Description

Technical Field

[0001] This application relates to the field of infant and toddler products technology, and in particular to a positioning component. Background Technology

[0002] A child safety seat, also known as a Child Restraint System (CRS), is a seat specifically designed for children and installed inside vehicles such as cars to effectively improve children's safety. Typically, a child safety seat consists of a base and a carrier body mounted on the base. The carrier body can rotate relative to the base to face different directions, and the positioning components can slide relative to the base to move in different directions. However, in currently common car child safety seats, the rotation and sliding of the carrier body relative to the base are achieved through different mechanical structures. This results in a relatively complex structure for the base and the overall child safety seat, making operation inconvenient. Utility Model Content

[0170] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0171] The first aspect of this utility model provides a vehicle A1000, which includes a vehicle body A200 and a positioning component A100 provided in some embodiments of this utility model. The vehicle body A200 can be fixedly mounted on the positioning component A100; alternatively, the vehicle body A200 can be detachably mounted on the positioning component A100. The vehicle body A200 can be mounted to a car seat (not shown in the figure) via the positioning component A100. The vehicle body A200 and the positioning component A100 will be described in conjunction with the following description of the vehicle A1000.

[0172] In one embodiment, the type of the vehicle body A200 may be, for example, a child safety seat (see...). Figure 14 Infant safety carrier (see) Figure 41 Users can choose the type of vehicle body A200 based on the child's age, height, or weight, such as a sleeping box or other suitable vehicle. Specifically, the bottom of the vehicle body A200 is equipped with a locking component A210 (see...). Figure 48 ).like Figure 1 and Figure 2As shown, the positioning component A100 may include a first positioning component A110 and a second positioning component A120. The first positioning component A110 is used to connect to the vehicle body A200, and the second positioning component A120 is used to connect to the vehicle seat. Specifically, the first positioning component A110 is provided with a first connecting mechanism A150, which is used for detachable connection with the engaging member A210 of the vehicle body A200. Specifically, the first connecting mechanism A150 includes an engaging hook A151, which is pivotally connected to the first positioning component A110 and has a locked position and an unlocked position. When the engaging hook A151 is in the locked position, it engages with the engaging member A210; when the engaging hook A151 is in the unlocked position, the engaging member A210 can disengage from the engaging hook A151, allowing the vehicle body A200 to disengage from the first positioning component A110. More specifically, the detailed structure of the first connecting mechanism A150 can be found in the following description. The second positioning component A120 is provided with a seat connecting mechanism A161 (e.g., an ISOFIX connector) and a support leg A162. The seat connecting mechanism A161 is mainly used to fix the second positioning component A120 to the car seat, and the support leg A162 is used to abut against the floor inside the vehicle to improve the reliability and stability of the installation of the positioning component A100.

[0173] In the positioning component A100 provided by the aforementioned vehicle A1000, one of the first positioning component A110 and the second positioning component A120 is provided with a first track A131 and a second track A132, and the other is provided with a first slider A141 and a second slider A142. Specifically, the first track A131 and the second track A132 are intersected to form an intersection center A133. The first track A131 is divided by the intersection center A133 to form a first track segment A1311 and a second track segment A1312, and the second track A132 is divided by the intersection center A133 to form a third track segment A1321 and a fourth track segment A1322. When the first slider A141 is located at the intersection center A133, the second slider A142 can be located at any one of the first track segment A1311, the second track segment A1312, the third track segment A1321, and the fourth track segment A1322. The first positioning component A110 rotates and slides relative to the second positioning component A120 by means of the first slider A141 sliding along one of the first track A131 or the second track A132 and the second slider A142 sliding along the other of the first track A131 or the second track A132.

[0174] To facilitate the following explanation of the working principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120, the intersection center A133 is regarded as point M or point N', the end of the first track segment A1311 away from the intersection center A133 is regarded as point N”, the end of the second track segment A1312 away from the intersection center A133 is regarded as point N, the end of the third track segment A1321 away from the intersection center A133 is regarded as point M', and the end of the fourth track segment A1322 away from the intersection center A133 is regarded as point M”.

[0175] See Figure 3 and Figure 4 In the positioning component A100 provided in the first embodiment, the second positioning component A120 is provided with a first track A131 and a second track A132 that are arranged in a cross configuration (see...). Figure 4 Specifically, the first track A131 extends along either the first direction F1 or the third direction F3, and the second track A132 extends along either the second direction F2 or the fourth direction F4. More specifically, the first track segment A1311 extends from the intersection center A133 towards the first direction F1, the second track segment A1312 extends from the intersection center A133 towards the third direction F3; the third track segment A1321 extends from the intersection center A133 towards the second direction F2, and the fourth track segment A1322 extends from the intersection center A133 towards the fourth direction F4. Wherein, the first direction F1 and the third direction F3 are parallel and opposite, the second direction F2 and the fourth direction F4 are parallel and opposite, and the first direction F1 and the second direction F2 intersect. More specifically, the first direction F1 and the second direction F2 are perpendicular. The first positioning component A110 is provided with a first sliding member A141 and a second sliding member A142 (see...). Figure 3 The first positioning component A110 has a rotation axis, the first sliding member A141 is coaxially arranged with the rotation axis, and the second sliding member A142 is offset from the rotation axis (see 3). Figure 15 , Figure 20 as well as Figure 23 Specifically, in this embodiment, when the first positioning component A110 is generally disk-shaped, the aforementioned rotation axis can be regarded as the center of the first positioning component A110. Of course, in other embodiments, the first positioning component A110 can be other symmetrical shapes (e.g., ellipse, rectangle, etc.), and the rotation axis can be the geometric center of the first positioning component A110 or a position off-center from the geometric center; or, the first positioning component A110 can also be asymmetrical, and the rotation axis can be set according to actual needs.

[0176] It should be noted that, taking the normal driving state of the car as a reference, the first direction F1 refers to the front of the car when the positioning component A100 is installed on the car seat, which is equivalent to the direction towards the front of the car. The third direction F3 can be regarded as the rear of the car when it is normally driving, which is the direction towards the rear of the car. The second direction F2 can be regarded as the left side of the car when it is normally driving, which is the direction towards the left side door of the car. The fourth direction F4 can be regarded as the right side of the car when it is normally driving, which is the direction towards the right side door of the car. In this embodiment, the first positioning component A110 has a front end, a rear end, a left end, and a right end. To clearly understand the various ends of the first positioning component A110, taking the vehicle body A200 installed on the first positioning component A110 as an example, the front-rear direction of the vehicle body A200 is parallel to the front-rear direction of the first positioning component A110, and the left-right direction of the vehicle body A200 is parallel to the left-right direction of the first positioning component A110. Specifically, when an infant or child is seated inside the vehicle body A200, the front end of the first positioning component A110 is closer to the infant's or child's feet than its rear end; conversely, the rear end of the first positioning component A110 is closer to the infant's or child's head than its front end; the left end of the first positioning component A110 is closer to the infant's or child's left hand than its right end; and the right end of the first positioning component A110 is closer to the infant's or child's right hand than its left end. When the first positioning component A110 faces a certain direction, it means that the vehicle body A200 is also facing that same direction; simultaneously, the child seated inside the vehicle body A200 is also facing that same direction. To visually understand the front-back and left-right directions of the vehicle body A200 and the first positioning component A110, arrows Q1 and Q3 are used to schematically indicate the "front" and "rear" directions, and arrows Q2 and Q4 are used to schematically indicate the "left" and "right" directions, respectively. In this context, direction Q1 is parallel to and opposite to direction Q3, direction Q2 is parallel to and opposite to direction Q4, and direction Q1 and direction Q2 intersect. Specifically, direction Q1 is perpendicular to direction Q2. These directional terms are used only to make the description of the embodiments of this utility model clearer and are not intended to unduly limit the scope of protection of this utility model. The following phrase, "the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120," means that the front end of the first positioning component A110 is oriented towards the first direction F1; "the first positioning component A110 is oriented towards the second direction F2 relative to the second positioning component A120," means that the front end of the first positioning component A110 is oriented towards the second direction F2; "the first positioning component A110 is oriented towards the third direction F3 relative to the second positioning component A120," means that the front end of the first positioning component A110 is oriented towards the third direction F3; "the first positioning component A110 is oriented towards the fourth direction F4 relative to the second positioning component A120," means that the front end of the first positioning component A110 is oriented towards the fourth direction F4.To clearly understand the setting position of the second slider A142 relative to the first slider A141 in the first embodiment, the setting position of the second slider A142 will be described below with reference to the first positioning component A110 being oriented toward the first direction F1 relative to the second positioning component A120, and the first positioning component A110 being approximately in a disk-shaped structure.

[0177] In the first embodiment, with respect to the first positioning component A110, when the first slider A141 is located at the rotation axis, the second slider A142 can be located behind the first slider A141 (see...). Figure 3 and Figure 8 This can be interpreted as follows: when the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120, the first slider A141 is located at the intersection center A133, and the second slider A142 is disposed on the side of the first slider A141 along the third direction F3, that is, the second slider A142 is located on the second track segment A1312. In this way, the first positioning component A110 can rotate and slide relative to the second positioning component A120 by means of the sliding action of the first slider A141 along the second track A132 and the sliding action of the second slider A142 along the first track A131.

[0178] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 under the action of the first sliding component A141 sliding along the second track A132 and the second sliding component A142 sliding along the first track A131.

[0179] Figure 1 A perspective view of positioning component A100 is shown when the first positioning component A110 is oriented in the first direction F1 relative to the second positioning component A120. Figure 2 A perspective view of positioning component A100 is shown when the first positioning component A110 is oriented toward a third direction F3 relative to the second positioning component A120. Figure 5 This can be viewed as a top view of positioning component A100 when the first positioning component A110 is oriented relative to the second positioning component A120 in the first direction F1 or the third direction F3 (the specific principle is explained later). In this view, the first positioning component A110 is rendered in perspective, and a virtual circular structure is used to replace it. Similarly, it can be... Figure 6 , Figure 7 , Figure 21 and Figure 22 The first positioning component A110 in the middle is made transparent.

[0180] like Figures 3 to 5 As shown, when the first slider A141 is located at the rotation axis and the second slider A142 is located behind the first slider A141 along the front-back direction of the first positioning component A110, when the first positioning component A110 is positioned relative to the second positioning component A120 and facing the first direction F1, the first slider A141 is located at the intersection center A133, i.e., point M or point N', and the second slider A142 is located at the end of the second track segment A1312 away from the intersection center A133, i.e., point N.

[0181] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2, it is equivalent to changing the vehicle body A200 from facing forward to facing left. For example... Figure 3 and Figure 4 As shown, the user can directly pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the first sliding member A141 to move from point M to point M' within the third track segment A1321, while simultaneously causing the second sliding member A142 to move synchronously from point N to point N' within the second track segment A1312. Figure 5 Switch to Figure 6 ,Depend on Figure 8 Switch to Figure 9 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves relative to the second positioning component A120 from the intersection center A133 in a lateral direction (specifically, along the left side, in the second direction F2), so as to protrude beyond the left edge of the second positioning component A120 (from...). Figure 1 Switch to Figure 12 When the first slider A141 moves to point M', the second slider A142 is located at point N', i.e., at the intersection center A133. At this time, the first positioning component A110 is oriented towards the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the second direction F2 relative to the second positioning component A120. It should be noted that the switching process of the first positioning component A110 relative to the second positioning component A120 towards the first direction F1 and the second direction F2 is reversible. That is, the orientation of the first positioning component A110 relative to the second positioning component A120 can be switched from towards the first direction F1 to towards the second direction F2, and also from towards the second direction F2 to towards the first direction F1.

[0182] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, it is equivalent to changing the vehicle body A200 from facing left to facing rear. Figure 3 and Figure 4 As shown, the user can pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the second sliding member A142 to move from point N' to point N” within the first track segment A1311, and simultaneously causes the first sliding member A141 to move synchronously from point M' to point M within the third track segment A1321. Figure 6 Switch to Figure 5 ,Depend on Figure 9 Switch to Figure 10 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while simultaneously moving relative to the second positioning component A120 from a lateral direction (specifically, the left side, i.e., the second direction F2) towards the intersection center A133. Figure 12 Switch to Figure 2 When the second slider A142 moves to point N", the first slider A141 is located at point M, i.e., the intersection center A133. At this time, the first positioning component A110 is oriented towards the third direction F3 relative to the second positioning component A120. Similarly, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the second direction F2 and the third direction F3 is reversible.

[0183] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing a third direction (F3) to facing a fourth direction (F4), it is equivalent to changing the orientation of the vehicle body A200 from facing rearward to facing rightward. Figure 3 and Figure 4 As shown, pulling the vehicle body A200 causes the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the first sliding member A141 to move from point M to point M” within the fourth track segment A1322, and simultaneously causes the second sliding member A142 to move from point N” to point N' within the first track segment A1311. Figure 5 Switch to Figure 7 ,Depend on Figure 10 Switch to Figure 11During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves relative to the second positioning component A120 from the intersection center A133 in a lateral direction (specifically, along the right side, i.e., the fourth direction F4), so as to protrude beyond the right edge of the second positioning component A120. Figure 2 Switch to Figure 13 When the first slider A141 moves to point M”, the second slider A142 is located at point N’, i.e., at the intersection center A133. At this time, the first positioning component A110 is oriented towards the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the fourth direction F4 relative to the second positioning component A120. Similarly, when the user needs to switch the setting of the first positioning component A110 relative to the second positioning component A120 from being oriented towards the fourth direction F4 to being oriented towards the first direction F4, the slider can be adjusted accordingly. During setup, it's equivalent to changing the orientation of the vehicle body A200 from right-facing to front-facing. Directly pulling the vehicle body A200 causes it to move the first positioning component A110, giving it a counter-clockwise rotation tendency. This allows the second sliding member A142 to move from point N' to point N within the second track segment A1312, simultaneously causing the first sliding member A141 to move from point M” to point M within the fourth track segment A1322 (from...). Figure 7 Switch to Figure 5 ,Depend on Figure 11 Switch to Figure 8 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while simultaneously moving relative to the second positioning component A120 from a lateral direction (specifically, the right-side direction, i.e., the fourth direction F4) towards the intersection center A133. Figure 13 Switch to Figure 1 Similarly, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the third direction F3 and the fourth direction F4 is reversible. The switching process of the first positioning component A110 relative to the second positioning component A120 towards the fourth direction F4 and the first direction F1 is also reversible.

[0184] It should be noted that the above description uses the example of the first positioning component A110 rotating one full circle counterclockwise relative to the second positioning component A120 to illustrate the principle of sliding while rotating. Of course, the principle of sliding while rotating can also be illustrated using the example of the first positioning component A110 rotating one full circle clockwise relative to the second positioning component A120, which will not be elaborated upon here.

[0185] In this embodiment, the distance R1 between the intersection center A133 and the end of the first track A131 is equal to the distance R3 between the first slider A141 and the second slider A142, i.e., R1 = R3. The distance R2 between the intersection center A133 and the end of the second track A132 is equal to the distance R3 between the first slider A141 and the second slider A142, i.e., R2 = R3. In other words, the length of each of the first track segment A1311, the second track segment A1312, the third track segment A1321, and the fourth track segment A1322 is equal to the distance R3 between the first slider A141 and the second slider A142. Of course, in other embodiments not shown, the distance R3 between the first slider A141 and the second slider A142 can be less than the distance R1 between the intersection center A133 and the end of the first track A131 and the distance R2 between the intersection center A133 and the end of the second track A132. In this way, when the first positioning component A110 rotates relative to the second positioning component A120 to face each direction, it can continue to slide in each direction. For example, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 to the second direction F2, the second slider A142 is located at the intersection center A133, i.e., point M, and the first slider A141 is located between the two ends of the third track segment A1321, i.e., between point M' and point M. At this time, the user can continue to pull the first positioning component A110 along the second direction F2 so that the first slider A141 and the second slider A142 move on the third track segment A1321 until the first slider A141 is located at the end of the third track segment A1321 away from the intersection center A133, i.e., point M'. Alternatively, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 to the second direction F2, the second slider A142 is located at the intersection center A133, i.e., point M, and the first slider A141 is located between the two ends of the third track segment A1321, i.e., between point M' and point M. At this time, the user can push the first positioning component A110 along the fourth direction F4 to move the first slider A141 and the second slider A142 from the third track segment A1321 to the fourth track segment A1322.

[0186] It should be noted that the first positioning component A110 can be a disk-shaped structure, with the rotation axis being the center of the disk. This makes the shape of the orthographic projection of the first positioning component A110 onto the second positioning component A120 symmetrical about the rotation axis of the first positioning component A110. Furthermore, when the lengths of the track segments are the same, the overlapping area and range between the first positioning component A110 and the second positioning component A120 when they are rotated relative to the first positioning component A110 and facing the first direction F1 are the same as the overlapping area and range when the first positioning component A110 is facing away from the first direction F1. In other words, when the first positioning component A110 is facing the second positioning component A120 relative to the first direction F1, the position of the orthographic projection of the first positioning component A110 onto the second positioning component A120 is the same as the position of the orthographic projection of the first positioning component A110 onto the second positioning component A120 when it is facing the third direction F3. Therefore... Figure 5 The vehicle body A200 shown can be viewed as either the first positioning component A110 rotating relative to the second positioning component A120 to face the first direction F1, or it can be viewed as rotating to face the third direction F3.

[0187] Based on the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 described above, it can be known that when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the direction of the second direction F2 or the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also be pulled outward relative to the second positioning component A120 to get closer to the car door (see the state). Figure 12 and Figure 13 Thus, when the vehicle body A200 connected to the first positioning component A110 rotates with the first positioning component A110 to face the second direction F2 or the fourth direction F4, it can move closer to the door (see state). Figure 14 In other words, when the first positioning component A110 is oriented in the second direction F2 or the fourth direction F4 relative to the second positioning component A120, the first positioning component A110 can simultaneously be pulled outward relative to the second positioning component A120 to get closer to the vehicle door (e.g., closer to the left or right door), thus facilitating the user to take the child out of or place the child into the vehicle body A200. That is, rotation (steering) and sliding (e.g., lateral pulling out) can be performed simultaneously. Furthermore, since there is no need to perform a steering operation followed by a lateral pulling out as in the traditional method, the ease of operation is improved.

[0188] In the positioning component A100 provided in the first embodiment, such as Figure 4As shown, the second positioning component A120 may include a second top cover A121 and a second bottom cover A122, which are connected vertically to form a second mounting cavity A123 (see...). Figure 8 See also Figure 3 , Figure 4 and Figure 8 Specifically, the first slider A141 may include a first sliding rod A1411 and a first slider A1412, and the second slider A142 may further include a second sliding rod A1421 and a second slider A1422. For example... Figures 8 to 10As shown, the first track A131 may include a first channel A1313 and a first groove A1314, and the second track A132 may include a second channel A1323 and a second groove A1324. Both the first channel A1313 and the second channel A1323 are located on the lower surface of the second top cover A121, facing the second mounting cavity A123. They intersect and communicate with each other, and both the first channel A1313 and the second channel A1323 are connected to the second mounting cavity A123. The first groove A1314 is located inside the first channel A1313, and the second groove A1324 is located inside the second channel A1323. Both the first groove A1314 and the second groove A1324 are through-slot structures. The first slider A141 is connected to the rotation axis of the first positioning assembly A110 via the first sliding rod A1411. The second slider A142 is connected to the first positioning assembly A110 via the second sliding rod A1421 and is offset from the rotation axis. The first sliding rod A1411 extends into the second slide groove A1324 and is connected to the first slider A1412. The second sliding rod A142 extends into the first slide groove A1314 and is connected to the second slider A1422. The first slider A141 slides along the second track A132 via the first slider A1412, and the second slider A142 slides along the first track A131 via the second slider A1422. Of course, in other embodiments, the first track A131 and the second track A132 can be groove structures provided on the upper surface of the second top cover A121. The first slider A141 can slide along the second track A132 via the first slider A1412, and the second slider A142 can slide along the first track A131 via the second slider A1422. It should be noted that the first slider A141 and the second slider A142 can both be integrally formed structures, that is, the first slider A1412 and the first sliding rod A1411 are integrally formed, and the second slider A1422 and the second sliding rod A1421 are integrally formed, and the second slider A1422 and the second sliding rod A1421 are integrally formed, and the second slider A1422 is integrally formed, and the second slider A1422 is integrally formed. Of course, in other embodiments, the first slider A1412 and the first sliding rod A1411 can be different components. The first slider A141 can be formed by connecting the first slider A1412 and the first sliding rod A1411 through welding, riveting, or other methods. The second slider A1422 and the second sliding rod A1421 can also be different components. The second slider A142 can be formed by connecting the second slider A1422 and the second sliding rod A1421 through welding, riveting, or other methods.

[0189] It should be noted that the above-mentioned "through groove structure" refers to a groove that is connected to the second mounting cavity A123, while the "groove structure" refers to a groove that is not connected to the second mounting cavity A123.

[0190] See Figure 4 and Figure 15The second embodiment of this utility model provides a positioning component A100, which can be regarded as a variation of the positioning component A100 in the first embodiment. The main difference lies in the different positions of the second sliding member A142. Unless otherwise specified, the following mainly describes the differences between this embodiment and the first embodiment described above.

[0191] Specifically, in the second embodiment, regarding the first positioning component A110, when the first slider A141 is located at the rotation axis, the second slider A142 can also be located in front of the first slider A141 along the front-back direction of the first positioning component A110 (see...). Figure 10 and Figure 15 When the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120, the first slider A141 is located at the intersection center A133, and the second slider A142 is located in front of the first slider A141, that is, on one side of the first slider A141 along the first direction F1. At this time, the second slider A142 is located on the first track segment A1311. In this way, the first positioning component A110 can also rotate and slide relative to the second positioning component A120 by means of the sliding action of the first slider A141 along the second track A132 and the sliding action of the second slider A142 along the first track A131.

[0192] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 under the action of the first sliding component A141 sliding along the second track A132 and the second sliding component A142 sliding along the first track A131.

[0193] It should be noted that when the illustrations related to the second slider A142 being located behind the first slider A141 are the same as those related to the second slider A142 being located in front of the first slider A141, the explanation of the relevant illustrations in the first embodiment can be referred to. Furthermore, the relationship between the distance between the first slider A141 and the second slider A142 and the length of each track segment can be referred to the description in the first embodiment. Specifically, when the first slider A141 is located at the rotation axis and the second slider A142 is located in front of the first slider A141, refer to... Figure 5 When the first positioning component A110 is positioned relative to the second positioning component A120 in the first direction F1, the first sliding member A141 is located at the intersection center A133, i.e., point M or point N', and the second sliding member A142 is located at the end of the first track segment A1311 away from the intersection center A133, i.e., point N”.

[0194] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2, it is equivalent to changing the vehicle body A200 from facing forward to facing left. For example... Figure 4 and Figure 15 The user can directly pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the first sliding member A141 to move from point M to point M” within the fourth track segment A1322, while simultaneously causing the second sliding member A142 to move synchronously from point N” to point N' within the first track segment A1311 (from M” to M”). Figure 5 Switch to Figure 7 ,Depend on Figure 10 Switch to Figure 11 It should be noted that the referenced in this embodiment is... Figure 7 , Figure 10 as well as Figure 11 The positioning component A100 shown is the same as the reference in the first embodiment. Figure 7 , Figure 10 as well as Figure 11 The positioning component A100 shown is slightly different in this embodiment, the difference being that: when the reference... Figure 7 and Figure 11 At that time, the first positioning components A110 are all oriented towards the second direction F2; while in the first embodiment, when the reference... Figure 7 and Figure 11 At that time, the first positioning component A110 is oriented towards the fourth direction F4. Additionally, in this embodiment, reference... Figure 10 At that time, the first positioning component A110 is oriented towards the first direction F1; while in the first embodiment, reference is... Figure 7 At this time, the first positioning component A110 is oriented towards the third direction F3. During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, it can move to the right relative to the second positioning component A120 from the intersection center A133, so as to be recessed relative to the left edge of the second positioning component A120 and protrude from the right edge (from the left edge of the second positioning component A120). Figure 1 Switch to Figure 16 That is, the first positioning component A110 rotates in the second direction F2 and moves in the fourth direction F4 at the same time. When the first slider A141 moves to point M”, the second slider A142 is located at point N’, that is, at the intersection center A133. At this time, the first positioning component A110 is facing the second direction F2 relative to the second positioning component A120, and the first positioning component A110 retracts inward along the second direction F2 relative to the second positioning component A120.

[0195] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, it is equivalent to changing the vehicle body A200 from facing left to facing rear. For example... Figure 4 and Figure 15 The user can pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the second sliding member A142 to move from point N' to point N within the second track segment A1312, while simultaneously causing the first sliding member A141 to move synchronously from point M” to point M within the fourth track segment A1322. Figure 7 Switch to Figure 5 ,Depend on Figure 11 Switch to Figure 8 Similarly, the referenced in this embodiment Figure 8 The positioning component A100 shown is the same as the reference in the first embodiment. Figure 8 The positioning component A100 shown in the previous embodiment is slightly different, the difference being: in this embodiment, the reference... Figure 8 At that time, the first positioning component A110 is oriented towards the third direction F3; while in the first embodiment, reference is... Figure 8 At this time, the first positioning component A110 is oriented in the first direction F1. During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, the first positioning component A110 moves relative to the second positioning component A120 from the right edge towards the intersection center A133 (from...). Figure 16 Switch to Figure 2 When the second slider A142 moves to N, the first slider A141 is located at point M, that is, at the intersection center A133. At this time, the first positioning component A110 is oriented towards the third direction F3 relative to the second positioning component A120.

[0196] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing a third direction (F3) to facing a fourth direction (F4), it is equivalent to changing the orientation of the vehicle body A200 from facing rearward to facing rightward. For example... Figure 4 and Figure 15 Pulling the vehicle body A200 causes the vehicle body A200 to move the first positioning component A110, giving the first positioning component A110 a tendency to rotate counterclockwise. This allows the first sliding member A141 to move from point M to point M' within the third track segment A1321, causing the second sliding member A142 to move synchronously from point N to point N' within the second track segment A1312. Figure 5 Switch to Figure 6 ,Depend on Figure 8 Switch to Figure 9 Similarly, the referenced in this embodiment Figure 6 and Figure 9 The positioning component A100 shown is the same as the reference in the first embodiment. Figure 6 and Figure 9 The positioning component A100 shown is slightly different in this embodiment, the difference being that: when the reference... Figure 6 and Figure 9 At that time, the first positioning component A110 is oriented towards the fourth direction F4; while in the first embodiment, the reference... Figure 6 and Figure 9 At this time, the first positioning component A110 faces the second direction F2. During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, it can move to the left relative to the second positioning component A120 from the intersection center A133, so as to be recessed relative to the right edge of the second positioning component A120 and protrude from the left edge (from...). Figure 2 Switch to Figure 18 That is, it turns towards the fourth direction F4 and moves towards the second direction F2. When the first slider A141 moves to point M', the second slider A142 is located at point N', that is, at the intersection center A133. At this time, the first positioning component A110 is facing the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is retracted inward along the fourth direction F4 relative to the second positioning component A120. Similarly, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the fourth direction F4 to facing the first direction F1, it is equivalent to changing the vehicle body A200 from facing to the right to facing forward. Directly pulling the vehicle body A200 causes it to move the first positioning component A110, giving it a counter-clockwise rotation tendency. This allows the second sliding member A142 to move from point N' to point N” within the first track segment A1311, and simultaneously causes the first sliding member A141 to move from point M' to point M within the second track segment A1312 (from...). Figure 6 Switch to Figure 5 ,Depend on Figure 9 Switch to Figure 10 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while simultaneously moving relative to the second positioning component A120 from the left edge towards the intersection center A133 (from...). Figure 18 Switch to Figure 1 ).

[0197] It should be noted that when the first slider A141 is located at the rotation axis and the second slider A142 is located in front of the first slider A141 along the front-back direction of the first positioning component A110, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the first direction F1 and the second direction F2 is reversible, as is the switching process towards the second direction F2 and the third direction F3. At the same time, the switching process towards the third direction F3 and the fourth direction F4 is reversible, and the switching process towards the fourth direction F4 and the first direction F1 is also reversible.

[0198] Based on the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 described above, it can be known that when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the direction of the second direction F2 or the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also retract inward relative to the second positioning component A120 to move away from the door on that side (see...). Figure 16 and Figure 18 Thus, the vehicle body A200 connected to the first positioning component A110 can move away from the side door when facing the second direction F2 or the fourth direction F4 (see...). Figure 17 and Figure 19 In other words, when the first positioning component A110 is oriented relative to the second positioning component A120 in either the second direction F2 or the fourth direction F4, the first positioning component A110 can retract inward relative to the second positioning component A120 to move away from the side door, preventing the vehicle body A200 from hitting the door or interfering with it when rotating to the side. Furthermore, the distance between the front end of the vehicle body A200 and the door is increased, providing more space for children to place their feet when riding in the side-positioned vehicle body A200. In addition, since there is no need to first turn and then retract laterally as in the traditional method, the ease of operation is improved.

[0199] It should be noted that in the above embodiments, the intersection center A133 can be the geometric center of the second positioning component A120. The second positioning component A120 is symmetrically arranged with respect to the axis of the first track A131. In this way, when the first positioning component A110 is oriented towards the second direction F2 or the fourth direction F4, the first positioning component A110 can protrude or retract relative to the second positioning component A120 to one side (e.g., the left or right side).

[0200] See Figure 4 and Figure 20The third embodiment of this utility model provides a positioning component A100, which can also be regarded as a variation of the positioning component A100 in the first embodiment. The main difference lies in the different positions of the second sliding member A142. Similarly, unless otherwise specified, the following mainly describes the differences between this embodiment and the first embodiment described above.

[0201] Specifically, in the third embodiment, regarding the first positioning component A110, when the first slider A141 is located at the rotation axis, the second slider A142 can also be located to the left of the first slider A141 along the front-back direction of the first positioning component A110 (see...). Figure 9 and Figure 20 This can be interpreted as follows: when the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120, and the first slider A141 is located at the intersection center A133, the second slider A142 is disposed on one side of the first slider A141 along the second direction F2, that is, the second slider A142 is located on the third track segment A1321. In this way, the first positioning component A110 can rotate and slide relative to the second positioning component A120 by means of the sliding action of the first slider A141 along the first track A131 and the sliding action of the second slider A142 along the second track A132.

[0202] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 under the action of the sliding of the first sliding component A141 along the first track A131 and the sliding of the second sliding component A142 along the second track A132.

[0203] Similarly, it should be noted that the relationship between the distance between the first slider A141 and the second slider A142 and the length of each track segment can be found in the first embodiment. Specifically, when the first slider A141 is located at the rotation axis and the second slider A142 is located to the left of the first slider A141, refer to... Figure 5 When the first positioning component A110 is positioned relative to the second positioning component A120 in the first direction F1, the first sliding member A141 is located at the intersection center A133, i.e., point M or point N', and the second sliding member A142 is located at the end of the third track segment A1321 away from the intersection center A133, i.e., point M'.

[0204] When the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2. For example... Figure 4 and Figure 20 The user can directly pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the first sliding member A141 to move from point M (i.e., point N') to point N” within the first track segment A1311, while simultaneously causing the second sliding member A142 to move synchronously from point M' to point M (i.e., point N') within the third track segment A1321. Figure 5 Switch to Figure 21 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves relative to the second positioning component A120 from the intersection center A133 along the longitudinal direction of the vehicle (specifically, forward movement, in the first direction F1), so that the first positioning component A110 can protrude from the front edge of the second positioning component A120 along the first direction F1 (see...). Figure 21 When the first slider A141 moves to point N”, the second slider A142 is located at point M (i.e. point N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented towards the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the first direction F1 relative to the second positioning component A120.

[0205] When the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, such as Figure 4 and Figure 20 The user can pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the second sliding member A142 to move from point M (i.e., point N') to point M” within the fourth track segment A1322. Simultaneously, the first sliding member A141 moves synchronously from point N” to point M (i.e., point N') within the first track segment A1311. Figure 21 Switch to Figure 5 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while simultaneously moving from the front edge towards the intersection center A133 relative to the second positioning component A120. When the second slider A142 moves to point M”, the first slider A141 is located at point M (i.e., point N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented towards the third direction F3 relative to the second positioning component A120.

[0206] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from a third-direction F3 setting to a fourth-direction F4 setting, such as... Figure 4 and Figure 20 Pulling the vehicle body A200 causes the vehicle body A200 to move the first positioning component A110, giving the first positioning component A110 a counterclockwise rotation tendency. This allows the first sliding member A141 to move from point M (i.e., point N') to point N within the second track segment A1312, and simultaneously causes the second sliding member A142 to move from point M” to point M (i.e., point N') within the fourth track segment A1322. Figure 5 Switch to Figure 22 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves relative to the second positioning component A120 from the intersection center A133 along the longitudinal direction of the vehicle (specifically, it moves rearward, third direction F3), so as to protrude beyond the rear end edge of the second positioning component A120 (see...). Figure 22 When the first slider A141 moves to point N, the second slider A142 is located at point M (i.e. N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented in the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the third direction F3 relative to the second positioning component A120. Similarly, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the fourth direction F4 to facing the first direction F1, the user directly pulls the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 has a counterclockwise rotation tendency. This allows the second sliding member A142 to move from point M (i.e., point N') to point M' within the third track segment A1321, causing the first sliding member A141 to simultaneously move from point N to point M (i.e., point N') within the second track segment A1312. Figure 22 Switch to Figure 5 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while the first positioning component A110 moves from the rear edge to the intersection center A133 relative to the second positioning component A120.

[0207] It should also be noted that when the first slider A141 is located at the rotation axis and the second slider A142 is located to the left of the first slider A141, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the first direction F1 and the second direction F2 is reversible, as is the switching process towards the second direction F2 and the third direction F3. At the same time, the switching process towards the third direction F3 and the fourth direction F4 is reversible, and the switching process towards the fourth direction F4 and the first direction F1 is also reversible.

[0208] Based on the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 described above, it can be seen that when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also move backward relative to the second positioning component A120 along the front-rear direction of the vehicle. Specifically, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the second direction F2, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also move forward relative to the second positioning component A120 along the driving direction of the vehicle (compared to...). Figure 5 and Figure 21 Taking a seven-seater vehicle as an example, the rear door of the car is usually installed on the second row of seats. Thus, for example, when the vehicle body A200 is installed on the third row of seats via the positioning component A100, when the vehicle body A200 rotates with the first positioning component A110 to face the left, i.e., the second direction F2, the distance between the vehicle body A200 and the rear left door can be reduced. This makes it convenient for the user to put a child into the vehicle body A200 or take a child out of the vehicle body A200 through the rear left door.

[0209] See Figure 4 and Figure 23 The fourth embodiment of this utility model provides a positioning component A100, which can be regarded as a variation of the positioning component A100 in the third embodiment. The main difference lies in the different positions of the second sliding member A142. Similarly, unless otherwise specified, the following mainly describes the differences between this embodiment and the third embodiment described above.

[0210] Specifically, in the fourth embodiment, regarding the first positioning component A110, when the first slider A141 is located at the rotation axis, the second slider A142 can also be located to the right of the first slider A141 along the front-back direction of the first positioning component A110 (see...). Figure 11and Figure 23 This can be interpreted as follows: when the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120, and the first slider A141 is located at the intersection center A133, the second slider A142 is located on one side of the first slider A141 along the fourth direction F4, that is, the second slider A142 is located on the fourth track segment A1322. In this way, the first positioning component A110 can also rotate and slide relative to the second positioning component A120 by means of the sliding action of the first slider A141 along the first track A131 and the sliding action of the second slider A142 along the second track A132.

[0211] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 under the action of the sliding of the first sliding component A141 along the first track A131 and the sliding of the second sliding component A142 along the second track A132.

[0212] Similarly, it should be noted that the relationship between the distance between the first slider A141 and the second slider A142 and the length of each track segment can be found in the first embodiment. Specifically, when the first slider A141 is located at the rotation axis and the second slider A142 is located to the right of the first slider A141, when the first positioning component A110 is positioned relative to the second positioning component A120 facing the first direction F1, the first slider A141 is located at the intersection center A133, i.e., point M or point N', and the second slider A142 is located at the end of the fourth track segment A1322 away from the intersection center A133, i.e., point M”.

[0213] When the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2. For example... Figure 4 and Figure 23 The user can pull the vehicle body A200, causing it to move the first positioning component A110, which then tends to rotate counterclockwise. This allows the first sliding member A141 to move from point M (i.e., point N') to point N within the second track segment A1312, while simultaneously causing the second sliding member A142 to move synchronously from point M” to point M (i.e., point N') within the fourth track segment A1322. Figure 5 Switch to Figure 22 It should be noted that the referenced in this embodiment is... Figure 22The positioning component A100 shown is the same as the reference in the third embodiment. Figure 22 The positioning component A100 shown in the previous embodiment is slightly different, the difference being: in this embodiment, the reference... Figure 22 At that time, the first positioning component A110 is oriented towards the second direction F2; while in the third embodiment, reference is made to... Figure 22 At this time, the first positioning component A110 is oriented in the fourth direction F4. During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, it can move relative to the second positioning component A120 from the intersection center A133 along the front-rear direction of the vehicle (specifically, it moves rearward, in the third direction F3), so as to protrude from the rear end edge of the second positioning component A120 (see...). Figure 22 When the first slider A141 moves to point N, the second slider A142 is located at point M (i.e. point N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented towards the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the third direction F3 relative to the second positioning component A120.

[0214] When the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, such as Figure 4 and Figure 23 The user can pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This allows the second sliding member A142 to move from point M (i.e., point N') to point M' within the third track segment A1321. Simultaneously, the first sliding member A141 moves synchronously from point N to point M (i.e., point N') within the second track segment A1312. Figure 22 Switch to Figure 5 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while simultaneously moving from the rear edge towards the intersection center A133 relative to the second positioning component A120. When the second slider A142 moves to point M', the first slider A141 is located at point M (i.e., point N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented towards the third direction F3 relative to the second positioning component A120.

[0215] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from a third-direction F3 setting to a fourth-direction F4 setting, such as... Figure 4 and Figure 23Pulling the vehicle body A200 causes the vehicle body A200 to move the first positioning component A110, giving the first positioning component A110 a tendency to rotate counterclockwise. This allows the first sliding member A141 to move from point M (i.e., point N') to point N” within the first track segment A1311, causing the second sliding member A142 to simultaneously move from point M' to point M (i.e., point N') within the fourth track segment A1322. Figure 5 Switch to Figure 21 Similarly, the referenced in this embodiment Figure 21 The positioning component A100 shown is the same as the reference in the third embodiment. Figure 21 The positioning component A100 shown in the previous embodiment is slightly different, the difference being: in this embodiment, the reference... Figure 21 At that time, the first positioning component A110 is oriented in the fourth direction F4; while in the third embodiment, reference is made to... Figure 21 At this time, the first positioning component A110 faces the second direction F2. During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, it can move forward and backward relative to the second positioning component A120 from the intersection center A133 along the longitudinal direction of the vehicle (specifically, forward, in the first direction F1), so that the first positioning component A110 can protrude from the front edge of the second positioning component A120 along the first direction F1 (see...). Figure 21 When the first slider A141 moves to point N”, the second slider A142 is located at point M (i.e., point N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented towards the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the first direction F1 relative to the second positioning component A120. Similarly, when the user needs to move the first positioning component A110 relative to the second positioning component A120 from the fourth direction F4... When the setting is switched to the orientation of the first direction F1, directly pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the second sliding member A142 can move from point M (i.e., point N') to point M” within the fourth track segment A1322, so that the first sliding member A141 moves synchronously from point N” to point M (i.e., point N') within the first track segment A1311. Figure 21 Switch to Figure 5 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while the first positioning component A110 moves from the front edge to the intersection center A133 relative to the second positioning component A120.

[0216] It should also be noted that when the first slider A141 is located at the rotation axis and the second slider A142 is located to the right of the first slider A141, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the first direction F1 and the second direction F2 is reversible, as is the switching process towards the second direction F2 and the third direction F3. At the same time, the switching process towards the third direction F3 and the fourth direction F4 is reversible, and the switching process towards the fourth direction F4 and the first direction F1 is also reversible.

[0217] Based on the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 described above, it can be seen that when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the second direction F2, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also move backward relative to the second positioning component A120 along the front-rear direction of the vehicle. Specifically, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also move forward relative to the second positioning component A120 along the driving direction of the vehicle (compared to...). Figure 5 and Figure 21 Similarly, taking a seven-seater vehicle as an example, when the vehicle body A200 is installed on the third-row seats via the positioning component A100, the distance between the vehicle body A200 and the rear right door can be reduced when the vehicle body A200 rotates with the first positioning component A110 to face the right, i.e., the fourth direction F4. This makes it convenient for users to put children into or take children out of the vehicle body A200 at the rear right door.

[0218] As described above, in the first to fourth embodiments, when the first slider A141 is positioned at the rotation axis, the second slider A142 can be positioned in front of, behind, to the left of, and to the right of the first positioning component A110 along the front-back direction. In each embodiment, the first positioning component A110 can slide while rotating relative to the second positioning component A120. This improves the convenience of user operation.

[0219] See Figure 24 and Figure 25The fifth embodiment of this utility model provides a positioning component A100, which can be considered a variation of the positioning component A100 in the first embodiment described above. The positioning component A100 in this embodiment also includes a first positioning component A110 and a second positioning component A120. The main difference from the positioning component A100 in the first embodiment is that the first positioning component A110 is provided with a first track A131 and a second track A132, and the second positioning component A120 is provided with a first sliding member A141 and a second sliding member A142. The first positioning component A110 also rotates and slides relative to the second positioning component A120 by means of the first sliding member A141 sliding along one of the first track A131 or the second track A132 and the second sliding member A142 sliding along the other of the first track A131 or the second track A132. Therefore, without conflict, the structure and connection relationship of the first positioning component A110 and the second positioning component A120 in this embodiment can be referred to the description in the first embodiment above. The following mainly describes the differences between this embodiment and the first embodiment above. It should be noted that in the positioning component A100 in this embodiment, the extension directions of the first track A131 and the second track A132 will change relative to each other during the rotation and sliding process with the first positioning component A110 (see the following description). In addition, it should be noted that in this embodiment, the first positioning component A110 can also be oriented relative to the second positioning component A120 in the first direction F1, the second direction F2, the third direction F3, and the fourth direction F4. The first direction F1, the second direction F2, the third direction F3, and the fourth direction F4 are the same as the first direction F1, the second direction F2, the third direction F3, and the fourth direction F4 referred to in the first embodiment above, that is, they can be regarded as the front of the car, the rear of the car, the left side of the car, and the right side of the car, respectively.

[0220] Specifically, in the positioning component A100 provided in the fifth embodiment, such as Figure 24 As shown, the first positioning component A110 has a first track A131 and a second track A132. The first track segment A1311 extends forward from the intersection center A133 along the front-rear direction of the first positioning component A110, i.e., along the Q1 direction; the second track segment A1312 extends backward from the intersection center A133 along the front-rear direction of the first positioning component A110, i.e., along the Q3 direction; the third track segment A1321 extends left from the intersection center A133 along the left-right direction of the first positioning component A110, i.e., along the Q2 direction; and the fourth track segment A1322 extends right from the intersection center A133 along the left-right direction of the first positioning component A110, i.e., along the Q4 direction. Figure 25As shown, the second positioning component A120 includes a first sliding member A141 and a second sliding member A142. The second positioning component A120 has a positioning axis. The first sliding member A141 is coaxially arranged with the positioning axis, and the second sliding member A142 is offset from the positioning axis. For example, the second sliding member A142 is located on the side of the first sliding member A141 along a third direction F3. Specifically, the positioning axis can be the geometric center of the second positioning component A120.

[0221] To better understand the setting position of the second slider A142 relative to the first slider A141 in the fifth embodiment, similarly to the first embodiment, the setting position of the second slider A142 will be described below with reference to the first positioning component A110 relative to the second positioning component A120 facing the first direction F1.

[0222] Specifically, in the fifth embodiment, regarding the second positioning component A120, when the first slider A141 is located at the positioning axis, the second slider A142 can be located behind the first slider A141 (see...). Figure 25 That is, the second slider A142 is disposed on the side of the first slider A141 along the third direction F3. When the first positioning component A110 is oriented relative to the second positioning component A120 in the first direction F1, as... Figure 26 As shown, the first track segment A1311 can be considered as extending from the intersection center A133 towards the first direction F1, the second track segment A1312 can be considered as extending from the intersection center A133 towards the third direction F3, the third track segment A1321 can be considered as extending from the intersection center A133 towards the second direction F2, and the fourth track segment A1322 can be considered as extending from the intersection center A133 towards the fourth direction F4. At this time, the first slider A141 is located at the intersection center A133, and the second slider A142 is located at the second track segment A1312. In this way, the first positioning component A110 rotates and slides relative to the second positioning component A120 by means of the sliding of the first slider A141 along the second track A132 and the sliding of the second slider A142 along the first track A131.

[0223] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 when the first sliding member A141 is located at the positioning axis of the second positioning component A120 and the second sliding member A142 is located behind the first sliding member A141, with the help of the sliding of the first sliding member A141 along the second track A132 and the sliding of the second sliding member A142 along the first track A131.

[0224] In the positioning component A100 provided in the fifth embodiment, such as Figure 24As shown, the first positioning component A110 may include a first top cover A111 and a first bottom cover A112. The first top cover A111 and the first bottom cover A112 are connected to form a first mounting cavity (not shown in the figure). Figures 26 to 29 A top view of positioning component A100 is shown when the first positioning component A110 is oriented in different directions relative to the second positioning component A120. This is done to clearly understand the principle of the simultaneous rotation and sliding of the first positioning component A110 relative to the second positioning component A120. Figures 26 to 29 The first positioning component A110 shown in the image only retains the first bottom cover A112.

[0225] like Figure 25 and Figure 26 As shown, when the first slider A141 is positioned at the positioning axis of the second positioning component A120, and the second slider A142 is positioned behind the first slider A141 along the first direction F1, when the first positioning component A110 is positioned relative to the second positioning component A120 and facing the first direction F1, the first slider A141 is located at the intersection center A133, i.e., point M or point N', and the second slider A142 is located at the end of the second track segment A1312 away from the intersection center A133, i.e., point N.

[0226] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2, it is equivalent to changing the vehicle body A200 from facing forward to facing left. For example... Figure 24 and Figure 25 As shown, the user can directly pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, allowing the first slider A141 to switch its position relative to the first positioning component A110 in the fourth track segment A1322 from point M to point M”. Simultaneously, the second slider A142 can switch its position relative to the first positioning component A110 in the second track segment A1312 from point N to point N' (from...). Figure 26 Switch to Figure 27 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can simultaneously move back and forth relative to the second positioning component A120 along the front-rear direction of the vehicle (specifically, move backward, along the third direction F3), so as to protrude beyond the rear end edge of the second positioning component A120 (see...). Figure 27When the first slider A141 moves to point M”, the second slider A142 is located at point N’, i.e., at the intersection center A133. At this time, the first positioning component A110 faces the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the third direction F3 relative to the second positioning component A120. It should be noted that when the first positioning component A110 rotates to face the second direction F2, at this time, as Figure 27 As shown, the first track segment A1311 can be considered as extending from the intersection center A133 to the second direction F2, the second track segment A1312 can be considered as extending from the intersection center A133 to the fourth direction F4, the third track segment A1321 can be considered as extending from the intersection center A133 to the third direction F3, and the fourth track segment A1322 can be considered as extending from the intersection center A133 to the first direction F1.

[0227] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, it is equivalent to changing the vehicle body A200 from facing left to facing rear. Figure 24 and Figure 25 As shown, the user can directly pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, allowing the second sliding member A142 to switch its position relative to the first positioning component A110 in the first track segment A1311 from point N' to point N”. Simultaneously, the position of the first sliding member A141 relative to the first positioning component A110 in the fourth track segment A1322 is synchronously switched from point M” to point M (from...). Figure 27 Switch to Figure 28 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves back and forth relative to the second positioning component A120 along the front-rear direction of the vehicle (specifically, it moves from the rear edge of the second positioning component A120 towards the position of the first sliding member A141, i.e., along the first direction F1). Thus, when the first positioning component A110 rotates relative to the second positioning component A120 to the third direction F3, its orthographic projection position on the second positioning component A120 is the same as the orthographic projection position on the second positioning component A120 when the first positioning component A110 rotates relative to the second positioning component A120 to the first direction F1 (see...). Figure 26 and Figure 28When the second slider A142 moves to point N", the first slider A141 is located at point M, i.e., the intersection center A133. At this time, the first positioning component A110 is oriented towards the third direction F3 relative to the second positioning component A120. It should be noted that when the first positioning component A110 rotates to face the third direction F3, at this time, as... Figure 28 As shown, the first track segment A1311 can be considered as extending from the intersection center A133 to the third direction F3, the second track segment A1312 can be considered as extending from the intersection center A133 to the first direction F1, the third track segment A1321 can be considered as extending from the intersection center A133 to the fourth direction F4, and the fourth track segment A1322 can be considered as extending from the intersection center A133 to the second direction F2.

[0228] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing a third direction (F3) to facing a fourth direction (F4), it is equivalent to changing the orientation of the vehicle body A200 from facing rearward to facing rightward. Figure 24 and Figure 25 As shown, pulling the vehicle body A200 causes the vehicle body A200 to move the first positioning component A110, giving the first positioning component A110 a tendency to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110. This allows the first sliding member A141 to switch its position relative to the first positioning component A110 in the third track segment A1321 from point M to point M'. Simultaneously, the second sliding member A142 can switch its position relative to the first positioning component A110 in the first track segment A1311 from point N” to point N' (from...). Figure 28 Switch to Figure 29 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can simultaneously move back and forth relative to the second positioning component A120 along the front-rear direction of the vehicle (specifically, backward, i.e., along the third direction F3), to protrude beyond the rear end edge of the second positioning component A120 (see...). Figure 29 When the first slider A141 moves to point M', the second slider A142 is located at point N', i.e., at the intersection center A133. At this time, the first positioning component A110 faces the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the third direction F3 relative to the second positioning component A120. It should be noted that when the first positioning component A110 rotates to face the fourth direction F4, at this time, as... Figure 29As shown, the first track segment A1311 can be considered as extending from the intersection center A133 to the fourth direction F4, the second track segment A1312 can be considered as extending from the intersection center A133 to the second direction F2, the third track segment A1321 can be considered as extending from the intersection center A133 to the first direction F1, and the fourth track segment A1322 can be considered as extending from the intersection center A133 to the third direction F3.

[0229] Similarly, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the fourth direction F4 to facing the first direction F1, it is equivalent to changing the vehicle body A200 from facing to the right to facing forward. Directly pulling the vehicle body A200 causes it to move the first positioning component A110, giving it a counter-clockwise rotation tendency. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, allowing the second slider A142 to switch its position relative to the first positioning component A110 in the second track segment A1312 from point N' to point N. Simultaneously, the first slider A141 can switch its position relative to the first positioning component A110 in the first track segment A1311 from point M' to point M. Figure 29 Switch to Figure 26 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, it can move back and forth relative to the second positioning component A120 along the front-rear direction of the car (specifically, it moves from the rear edge of the second positioning component A120 towards the position of the first sliding member A141, that is, it moves along the first direction F1) to reset.

[0230] Similarly, it should be noted that when the first slider A141 is located at the positioning axis of the second positioning component A120 and the second slider A142 is located behind the first slider A141, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the first direction F1 and the second direction F2 is reversible, as is the switching process towards the second direction F2 and the third direction F3, the switching process towards the third direction F3 and the fourth direction F4, and the switching process towards the fourth direction F4 and the first direction F1 is also reversible.

[0231] Similarly, it should be noted that the above description uses the example of the first positioning component A110 rotating one full circle counterclockwise relative to the second positioning component A120 to illustrate the principle of sliding while rotating. Of course, the principle of sliding while rotating can also be illustrated using the example of the first positioning component A110 rotating one full circle clockwise relative to the second positioning component A120, which will not be elaborated here.

[0232] See Figure 24 and Figure 30 The sixth embodiment of this utility model provides a positioning component A100, which can be considered a variation of the positioning component A100 in the fifth embodiment. The main difference lies in the position of the second sliding member A142. Therefore, unless otherwise specified, the following mainly describes the differences between this embodiment and the fifth embodiment described above.

[0233] Specifically, in the sixth embodiment, regarding the second positioning component A120, when the first slider A141 is disposed at the positioning axis, the second slider A142 can also be disposed in front of the first slider A141 (see...). Figure 30 The second slider A142 is disposed on one side of the first slider A141 along the first direction F1. When the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120, the first slider A141 is located at the intersection center A133, and the second slider A142 is located at the first track segment A1311. In this way, the first positioning component A110 can also rotate and slide relative to the second positioning component A120 by means of the sliding of the first slider A141 along the second track A132 and the sliding of the second slider A142 along the first track A131.

[0234] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 when the first sliding member A141 is located at the positioning axis of the second positioning component A120 and the second sliding member A142 is located in front of the first sliding member A141, with the help of the sliding of the first sliding member A141 along the second track A132 and the sliding of the second sliding member A142 along the first track A131.

[0235] Specifically, when the first slider A141 is located at the positioning axis of the second positioning component A120, and the second slider A142 is located in front of the first slider A141, when the first positioning component A110 is positioned relative to the second positioning component A120 facing the first direction F1, the first slider A141 is located at the intersection center A133, i.e., point M or point N', and the second slider A142 is located at the end of the first track segment A1311 away from the intersection center A133, i.e., point N” (see...). Figure 26 ).

[0236] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2, it is equivalent to changing the vehicle body A200 from facing forward to facing left. For example... Figure 24 and Figure 30 The user can pull the vehicle body A200, causing it to move the first positioning component A110, resulting in a counter-clockwise rotation of the first positioning component A110. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, allowing the first slider A141 to switch its position relative to the first positioning component A110 within the second track segment A1312 from point M to point M'. Simultaneously, the second slider A142 can synchronously switch its position relative to the first positioning component A110 within the first track segment A1311 from point N” to point N'. Figure 26 Switch to Figure 31 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves relative to the second positioning component A120 in the forward-backward direction of the vehicle (specifically, forward movement, in the first direction F1), so that the first positioning component A110 protrudes from the front edge of the second positioning component A120 in the first direction F1 (see...). Figure 31 When the first slider A141 moves to point M', the second slider A142 is located at point N', i.e., at the intersection center A133. At this time, the first positioning component A110 is oriented towards the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the first direction F1 relative to the second positioning component A120.

[0237] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, it is equivalent to changing the vehicle body A200 from facing left to facing rear. Figure 24 and Figure 30 The user can directly pull the vehicle body A200, causing it to move the first positioning component A110, which then tends to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, resulting in the second slider A142 changing its position from point N' to point N within the second track segment A1312. Simultaneously, the first slider A141's position within the third track segment A1321 changes synchronously from point M' to point M. Figure 31 Switch to Figure 28During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves relative to the second positioning component A120 along the longitudinal direction of the vehicle (specifically, it moves from the front edge of the second positioning component A120 towards the position of the first sliding member A141, in the third direction F3). Thus, when the first positioning component A110 rotates relative to the second positioning component A120 to the third direction F3, its orthographic projection position on the second positioning component A120 is the same as the orthographic projection position on the second positioning component A120 when the first positioning component A110 rotates relative to the second positioning component A120 to the first direction F1 (see...). Figure 26 and Figure 28 When the second slider A142 moves to point N, the first slider A141 is located at point M, i.e., at the intersection center A133. At this time, the first positioning component A110 is oriented towards the third direction F3 relative to the second positioning component A120.

[0238] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing a third direction (F3) to facing a fourth direction (F4), it is equivalent to changing the orientation of the vehicle body A200 from facing rearward to facing rightward. Figure 24 and Figure 30 Pulling the vehicle body A200 causes it to move the first positioning component A110, resulting in a counter-clockwise rotation of the first positioning component A110. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110. Consequently, the position of the first sliding member A141 within the fourth track segment A1322 changes from point M to point M', and the position of the second sliding member A142 within the second track segment A1312 changes synchronously from point N to point N'. Figure 28 Switch to Figure 32 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and simultaneously moves back and forth relative to the second positioning component A120 along the longitudinal direction of the vehicle (specifically, forward movement, in the first direction F1), so that the first positioning component A110 can protrude from the front edge of the second positioning component A120 along the first direction F1 (see...). Figure 32When the first slider A141 moves relative to M”, the second slider A142 is located at point N’, i.e., at the intersection center A133. At this time, the first positioning component A110 is oriented towards the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the first direction F1 relative to the second positioning component A120. Similarly, when the user needs to switch the setting of the first positioning component A110 relative to the second positioning component A120 from being oriented towards the fourth direction F4 to being oriented towards the first direction F1, it is equivalent to needing to move the vehicle body A200 from being oriented towards the fourth direction F4 to being oriented towards the first direction F1. Change the orientation from right to forward, directly pull the vehicle body A200, causing the vehicle body A200 to move the first positioning component A110, so that the first positioning component A110 tends to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, causing the position of the second slider A142 within the first track segment A1311 to switch from point N' to point N”, and simultaneously causing the position of the first slider A141 within the second track segment A1312 to switch from point M” to point M (from 32 to...). Figure 26 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, it can move back and forth relative to the second positioning component A120 in the front-rear direction of the car (specifically, it moves from the front edge of the second positioning component A120 towards the position of the first sliding member A141, and then in the third direction F3) to reset.

[0239] Similarly, when the first slider A141 is located at the positioning axis of the second positioning component A120 and the second slider A142 is located in front of the first slider A141, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the first direction F1 and the second direction F2 is reversible, the switching process towards the second direction F2 and the third direction F3 is reversible, the switching process towards the third direction F3 and the fourth direction F4 is reversible, and the switching process towards the fourth direction F4 and the first direction F1 is also reversible.

[0240] Based on the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 described above, it can be known that when the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2, the first positioning component A110 can move forward relative to the second positioning component A120 along the driving direction of the vehicle (see...). Figure 31 and Figure 32Taking a seven-seater vehicle as an example, the rear door of the car is usually installed on the second row of seats. Thus, when the vehicle body A200 is installed on the third row of seats via the positioning component A100, the distance between the vehicle body A200 and the rear door can be reduced when the vehicle body A200 is rotated with the first positioning component A110 to face the left or right, i.e., the second direction F2 or the fourth direction F4. This makes it convenient for users to put children into or take children out of the vehicle body A200 at the rear door.

[0241] See Figure 24 and Figure 33 The seventh embodiment of this utility model provides a positioning component A100, which can be considered a variation of the positioning component A100 in the fifth embodiment. The main difference lies in the position of the second sliding member A142. Therefore, unless otherwise specified, the following mainly describes the differences between this embodiment and the fifth embodiment described above.

[0242] Specifically, in the seventh embodiment, regarding the second positioning component A120, when the first slider A141 is located at the positioning axis, the second slider A142 can be located to the left of the first slider A141 (see...). Figure 33 That is, the second slider A142 is located on the side of the first slider A141 along the second direction F2. When the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120, the first slider A141 is located at the intersection center A133, and at this time, the second slider A142 is located at the third track segment A1321. In this way, the first positioning component A110 can rotate and slide relative to the second positioning component A120 by means of the sliding of the first slider A141 along the first track A131 and the sliding of the second slider A142 along the second track A132.

[0243] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 when the first sliding member A141 is located at the positioning axis of the second positioning component A120 and the second sliding member A142 is located to the left of the first sliding member A141 (i.e., the second sliding member A142 is located on the side of the first sliding member A141 along the second direction F2).

[0244] Specifically, when the first slider A141 is located at the positioning axis of the second positioning component A120, and the second slider A142 is located to the left of the first slider A141 along the first direction F1, when the first positioning component A110 is positioned relative to the second positioning component A120 and facing the first direction F1, the first slider A141 is located at the intersection center A133, i.e., point M or point N', and the second slider A142 is located at the end of the third track segment A1321 away from the intersection center A133, i.e., point M'.

[0245] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2, it is equivalent to changing the vehicle body A200 from facing forward to facing left. For example... Figure 24 and Figure 33 The user can directly pull the vehicle body A200, causing it to move the first positioning component A110, which then tends to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, switching the position of the first slider A141 within the third track segment A1321 from point M (i.e., point N') to point N. Simultaneously, the position of the second slider A142 within the second track segment A1312 also switches synchronously from point M' to point M (i.e., point N'). Figure 26 Switch to Figure 34 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can simultaneously move laterally relative to the second positioning component A120 in the longitudinal direction of the vehicle (specifically, it moves in the left-hand direction, the second direction F2), so as to protrude beyond the left edge of the second positioning component A120 (see...). Figure 34 When the first slider A141 moves to point N, the second slider A142 is located at point M (i.e., point N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented towards the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the second direction F2 relative to the second positioning component A120.

[0246] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, it is equivalent to changing the vehicle body A200 from facing left to facing rear. Figure 24 and Figure 33The user can pull the vehicle body A200, causing it to move the first positioning component A110, which then tends to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110. This causes the position of the second slider A142 within the fourth track segment A1322 to switch from point M (i.e., point N') to point M”. Simultaneously, the position of the first slider A141 within the second track segment A1312 also switches synchronously from point N to point M (i.e., point N'). Figure 34 Switch to 28). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while simultaneously moving from a lateral direction (specifically, the left side) towards the position of the first slider A141 (i.e., towards the positioning axis) relative to the second positioning component A120. When the second slider A142 moves to point M”, the first slider A141 is located at point M (i.e., point N'), which is the intersection center A133. At this time, the first positioning component A110 is facing the third direction F3 relative to the second positioning component A120.

[0247] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing a third direction (F3) to facing a fourth direction (F4), it is equivalent to changing the orientation of the vehicle body A200 from facing rearward to facing rightward. Figure 24 and Figure 33 Pulling the vehicle body A200 causes it to move the first positioning component A110, resulting in a counter-clockwise rotation of the first positioning component A110. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110. Consequently, the position of the first sliding member A141 within the first track segment A1311 changes from point M (i.e., point N') to point N”, and the position of the second sliding member A142 within the fourth track segment A1322 changes synchronously from point M” to point M (i.e., point N'). Figure 28 Switch to Figure 35 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can simultaneously move laterally relative to the second positioning component A120 in the longitudinal direction of the vehicle (specifically, in the left direction, the second direction F2), so as to retract relative to the right edge of the second positioning component A120 and protrude from the left edge (see...). Figure 35When the first slider A141 moves to point N”, the second slider A142 is located at point M (i.e., point N'), which is the intersection center A133. At this time, the first positioning component A110 is oriented towards the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is retracted inward along the fourth direction F4 relative to the second positioning component A120. Similarly, when the user needs to switch the setting of the first positioning component A110 relative to the second positioning component A120 from being oriented towards the fourth direction F4 to being oriented towards the first direction F1, it is equivalent to needing to change the orientation of the vehicle body A200 from being oriented towards the fourth direction F4 to being oriented towards the first direction F1. The right-side setting is changed to a forward-facing setting. Directly pulling the vehicle body A200 causes it to move the first positioning component A110, resulting in a counter-clockwise rotation of the first positioning component A110. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110. Consequently, the position of the second slider A142 within the third track segment A1321 changes from point M (i.e., point N') to point M'. Simultaneously, the position of the first slider A141 within the first track segment A1311 changes from point N” to point M (i.e., point N'). Figure 35 Switch to 26). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time, the first positioning component A110 moves relative to the second positioning component A120 from the lateral direction (specifically the left side direction) towards the position where the first slider A141 is located (which can be regarded as the positioning axis).

[0248] Similarly, when the first slider A141 is located at the rotation axis of the second positioning component A120 and the second slider A142 is located to the left of the first slider A141, the switching process of the first positioning component A110 relative to the second positioning component A120 towards the first direction F1 and the second direction F2 is reversible, the switching process towards the second direction F2 and the third direction F3 is reversible, the switching process towards the third direction F3 and the fourth direction F4 is reversible, and the switching process towards the fourth direction F4 and the first direction F1 is also reversible.

[0249] Based on the principle and process of the first positioning component A110 rotating and sliding relative to the second positioning component A120 as described above, it can be known that when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the direction of the second direction F2 or the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also be pulled outward along the second direction F2 or retracted inward along the fourth direction F4 relative to the second positioning component A120. In some embodiments, the first track segment A1311 can be selectively cancelled, that is, the first track A131 only includes the second track segment A1312. In this case, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the direction F2, the first positioning component A110 can be pulled outward relative to the second positioning component A120 along the second direction F2. In this way, the vehicle body A200 connected to the first positioning component A110 can be closer to the door when it rotates with the first positioning component A110 to the second direction F2, thereby making it convenient for the user to take the child out of the vehicle body A200 or put the child into the vehicle body A200. Similarly, in some other embodiments, the second track segment A1312 can be selectively omitted, that is, the first track A131 only includes the first track segment A1311. In this case, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also retract inward relative to the second positioning component A120 along the fourth direction F4 to move away from the door. When a child is riding in the vehicle body A200 which is set to the side (specifically facing the right door), this can prevent the child from hitting the door when turning to the side-facing use state, and also provide more space for placing feet in the side-facing use state. In addition, since it is not necessary to first turn and then perform the operation of pulling outward or pushing inward laterally as in the traditional way, the convenience of operation is improved.

[0250] See Figure 24 and Figure 36 The eighth embodiment of this utility model provides a positioning component A100, which can be considered a variation of the positioning component A100 in the fifth embodiment. The main difference lies in the position of the second sliding member A142. Therefore, unless otherwise specified, the following mainly describes the differences between this embodiment and the fifth embodiment described above.

[0251] Specifically, in the eighth embodiment, regarding the second positioning component A120, when the first slider A141 is located at the positioning axis, the second slider A142 can also be located to the right of the first slider A141 (see...). Figure 36 That is, the second slider A142 is located on one side of the first slider A141 along the fourth direction F4. When the first positioning component A110 is oriented towards the first direction F1 relative to the second positioning component A120, the first slider A141 is located at the intersection center A133, and the second slider A142 is located at the fourth track segment A1322. In this way, the first positioning component A110 can also rotate and slide relative to the second positioning component A120 by means of the sliding action of the first slider A141 along the first track A131 and the sliding action of the second slider A142 along the second track A132.

[0252] The following, with reference to relevant diagrams, briefly explains the principle and process by which the first positioning component A110 in the positioning component A100 rotates and slides relative to the second positioning component A120 when the first sliding member A141 is located at the positioning axis of the second positioning component A120 and the second sliding member A142 is located to the right of the first sliding member A141 (i.e., the second sliding member A142 is located on the side of the first sliding member A141 along the fourth direction F4).

[0253] Specifically, when the first slider A141 is located at the positioning axis of the second positioning component A120, and the second slider A142 is located to the right of the first slider A141, when the first positioning component A110 is positioned relative to the second positioning component A120 and facing the first direction F1, the first slider A141 is located at the intersection center A133, i.e., point M or point N', and the second slider A142 is located at the end of the fourth track segment A1322 away from the intersection center A133, i.e., point M” (see...). Figure 26 ).

[0254] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the first direction F1 to facing the second direction F2, it is equivalent to changing the vehicle body A200 from facing forward to facing left. For example... Figure 24 and Figure 36 The user can directly pull the vehicle body A200, causing it to move the first positioning component A110, resulting in a counter-clockwise rotation of the first positioning component A110. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, switching the position of the first slider A141 within the first track segment A1311 from point M or N' to point N”. Simultaneously, the position of the second slider A142 within the fourth track segment A1322 also switches synchronously from point M” to point M or N'. Figure 26 Switch to Figure 37During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can simultaneously move laterally relative to the second positioning component A120 in the longitudinal direction of the vehicle (specifically, in the right-hand direction, fourth direction F4), so as to retract relative to the left edge of the second positioning component A120 and protrude beyond the right edge (see...). Figure 37 ), that is, it retracts inward along the left side. When the first slider A141 moves to point N”, the second slider A142 is located at point M or point N', that is, at the intersection center A133. At this time, the first positioning component A110 is oriented towards the second direction F2 relative to the second positioning component A120, and the first positioning component A110 retracts inward along the second direction F2 relative to the second positioning component A120.

[0255] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the second direction F2 to facing the third direction F3, it is equivalent to changing the vehicle body A200 from facing left to facing rear. Figure 24 and Figure 36 The user can pull the vehicle body A200, causing it to move the first positioning component A110, which then tends to rotate counterclockwise. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, resulting in the second slider A142 changing its position within the third track segment A1321 from point M or N' to point M'. Simultaneously, the first slider A141's position within the first track segment A1311 changes synchronously from point N' to point M or N'. Figure 37 Switch to Figure 28 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, while simultaneously moving from a lateral direction (specifically, the right side) towards the position of the first sliding member A141 (i.e., towards the positioning axis) relative to the second positioning component A120. Thus, when the first positioning component A110 rotates relative to the second positioning component A120 to a third direction F3, its orthographic projection onto the second positioning component A120 is at the same position as its orthographic projection relative to the second positioning component A120 rotating to a first direction F1. When the second sliding member A142 moves relative to point M', the first sliding member A141 is located at point M or point N', i.e., at the intersection center A133, at which point the first positioning component A110 faces the third direction F3 relative to the second positioning component A120.

[0256] Furthermore, when the user needs to switch the orientation of the first positioning component A110 relative to the second positioning component A120 from facing a third direction (F3) to facing a fourth direction (F4), it is equivalent to changing the orientation of the vehicle body A200 from facing rearward to facing rightward. Figure 24 and Figure 36 Pulling the vehicle body A200 causes it to move the first positioning component A110, resulting in a counter-clockwise rotation of the first positioning component A110. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110. This causes the position of the first sliding member A141 within the second track segment A1312 to change from point M or N' to point N, and simultaneously causes the position of the second sliding member A142 within the third track segment A1321 to change from point M' to point M or N'. Figure 28 Switch to Figure 38 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can simultaneously move laterally relative to the second positioning component A120 in the longitudinal direction of the vehicle (specifically, in the right-hand direction, i.e., the fourth direction F4), so as to protrude relative to the right edge of the second positioning component A120 (see...). Figure 38 When the first slider A141 moves to point N, the second slider A142 is located at point M or point N', that is, at the intersection center A133. At this time, the first positioning component A110 is oriented towards the fourth direction F4 relative to the second positioning component A120, and the first positioning component A110 is pulled outward along the fourth direction F4 relative to the second positioning component A120. Similarly, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from facing the fourth direction F4 to facing the first direction F1, it is equivalent to changing the vehicle body A200 from facing to the right to facing forward. Directly pulling the vehicle body A200 causes it to move the first positioning component A110, resulting in a counter-clockwise rotation of the first positioning component A110. This causes the first track A131 and the second track A132 to rotate simultaneously with the first positioning component A110, causing the position of the second slider A142 within the fourth track segment A1322 to switch from point M or N' to point M”. This also causes the position of the first slider A141 within the second track segment A1312 to switch synchronously from point N to point M or N'. Figure 38 Switch to Figure 26 During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120. At the same time, the first positioning component A110 moves from the lateral direction (specifically the right side direction) relative to the second positioning component A120 towards the position of the first sliding member A141 (which can be regarded as the positioning axis) to reset.

[0257] It should be noted that when the first slider A141 is located at the positioning axis of the second positioning component A120 and the second slider A142 is located to the right of the first slider A141, the first positioning component A110 is reversible in the switching process relative to the second positioning component A120 towards the first direction F1 and the second direction F2, and is also reversible in the switching process towards the second direction F2 and the third direction F3, as well as in the switching process towards the third direction F3 and the fourth direction F4, and is also reversible in the switching process towards the fourth direction F4 and the first direction F1.

[0258] Based on the principle and process of the first positioning component A110 rotating and sliding relative to the second positioning component A120 as described above, it can be known that when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the direction of the second direction F2 or the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also be pulled outward along the fourth direction F4 or retracted inward along the second direction F2 relative to the second positioning component A120. In some embodiments, the second track segment A1312 can be selectively omitted, that is, the first track A131 only includes the first track segment A1311. In this case, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the direction F2, the first positioning component A110 can retract inward relative to the second positioning component A120 towards the second direction F2 to move away from the door. When a child sits on the vehicle body A200 which is set to the side (specifically facing the left door), this can prevent the child from hitting the door when turning to the side use state, and also provide a large space for placing feet in the side use state. Similarly, in some other embodiments, the first track segment A1311 can be selectively omitted, that is, the first track A131 only includes the second track segment A1312. In this case, when the first positioning component A110 rotates relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and at the same time, it can also be pulled outward relative to the second positioning component A120 along the fourth direction F4 to get closer to the door. In this way, the vehicle body A200 connected to the first positioning component A110 can be closer to the door, thereby making it easier for the user to take the child out of the vehicle body A200 or put the child into the vehicle body A200. In addition, since it is not necessary to turn first and then perform the operation of pulling outward or pushing inward laterally as in the traditional way, the convenience of operation is improved. Of course, in some other embodiments not shown, the first track segment A1311 and the second track segment A1312 may be retained, and the positioning component A100 also includes a blocking mechanism (see below). This blocking mechanism may be provided on the movement path of the first slider A141 along the first track segment A1311 to restrict the first positioning component A110 from rotating relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the direction F2. In this way, the vehicle body A200 can only rotate with the first positioning component A110 to the direction F4 to be pulled outward to the right, thereby improving the convenience of picking up and placing children laterally (specifically to the right).Alternatively, the blocking mechanism can be set on the movement path of the first slider A141 along the second track segment A1312 to restrict the first positioning component A110 from rotating relative to the second positioning component A120 from the first direction F1 or the third direction F3 to the fourth direction F4. In this way, the vehicle body A200 can only rotate with the first positioning component A110 to the second direction F2 to retract inward to the left, so as to avoid hitting the left door when using the vehicle body A200 laterally (specifically to the left), while increasing the foot placement space when using it laterally.

[0259] As described above, in the fifth to eighth embodiments, when the first slider A141 is positioned at the positioning axis of the second positioning component A120, the second slider A142 can be positioned in front of, behind, to the left of, and to the right of the first slider A141. In each embodiment, the first positioning component A110 can slide while rotating relative to the second positioning component A120. This improves the convenience of user operation.

[0260] It should be noted that the "first sliding member A141" and "second sliding member A142" in the embodiments of the first aspect can be collectively referred to as sliding components. Furthermore, it should be noted that in the embodiments of this aspect, when the first positioning component A110 protrudes relative to the second positioning component A120 towards one side (such as the left or right side), it means that the geometric center of the first positioning component A110 relative to the second positioning component A120 is displaced to one side. The vehicle body A200 can also be considered to have undergone lateral displacement relative to the second positioning component A120, so that the front end of the vehicle body A200 (the position where the child's feet are placed) is closer to that side door. When the first positioning component A110 retracts relative to the second positioning component A120 toward one side (such as the left or right side) of the second positioning component A120, the geometric center of the first positioning component A110 relative to the second positioning component A120 is displaced to the opposite side. The vehicle body A200 will also retract laterally relative to the second positioning component A120 so that the front end of the vehicle body A200 (the position where the child's feet are placed) moves away from the door on that side.

[0261] The second aspect of this utility model provides a carrier A1000, which includes a carrier body A200 and a positioning component A100 provided in some embodiments of this utility model. The carrier body A200 can be fixedly mounted on the positioning component A100; alternatively, the carrier body A200 can be detachably mounted on the positioning component A100. In the carrier A1000 provided in this embodiment, the carrier body A200 is the same as the carrier body A200 in the previously described embodiments. The positioning component A100 is similar to the positioning component A100 in the previously described embodiments, including components such as a first positioning component A110 and a second positioning component A120. Specifically, the positioning component A100 in this embodiment can be considered a variation of the previously described positioning component A100. Therefore, unless otherwise specified, the structure of the first positioning component A110, the second positioning component A120, and other components, as well as the connection relationships between the components, in this embodiment can be referred to the description in the above embodiment. The following mainly describes the differences between this embodiment and the above embodiment.

[0262] Specifically, in some embodiments, the positioning component A100 also includes a first positioning component A110 and a second positioning component A120. The first positioning component A110 is used to connect to the vehicle body A200; the second positioning component A120 is used to connect to the vehicle seat. One of the first positioning component A110 and the second positioning component A120 is provided with a first track A131 and a second track A132, and the other is provided with a sliding component A143. For example, the first positioning component A110 is provided with a first track A131 and a second track A132, and the second positioning component A120 is provided with a sliding component A143. Specifically, the first track A131 and the second track A132 intersect, and the sliding component A143 is capable of rotating within the first track A131 and sliding within the second track A132. The first positioning component A110 rotates within the first track A131 relative to the second positioning component A120 via the sliding component A143, and slides within the second track A132 relative to the second positioning component A120 via the sliding component A143. More specifically, in this embodiment, the first positioning component A110 is provided with the sliding component A143, and the second positioning component A120 is provided with the first track A131 and the second track A132. The first track A131 and the second track A132 are connected at their intersection, and the sliding component A143 can slide continuously between the first track A131 and the second track A132. It should be noted that "continuous sliding" means that the sliding component A143 moves continuously along the direction of the track between the first track A131 and the second track A132. This movement can be a back-and-forth movement between the two tracks, or a continuous unidirectional or reciprocating movement between the two tracks along a certain direction.

[0263] See Figure 39 and Figure 40 In the positioning component A100 provided in the first embodiment of the second aspect, the first positioning component A110 is provided with a sliding component A143, and the second positioning component A120 is provided with a first track A131 and a second track A132. The first track A131 includes a first channel A1313, which has a circular structure, and the center of the first channel A1313 may coincide with or be offset from the geometric center of the second positioning component A120. Specifically, the center of the first channel A1313 coincides with the geometric center of the second positioning component A120, and when the first positioning component A110 is mounted on the second positioning component A120 and the sliding component A143 is located within the first channel A1313, the center of the first channel A1313 is coaxially arranged with the center of the first positioning component A110. The second track A132 extends along a second direction F2 or a fourth direction F4 (i.e., opposite to the second direction F2). Specifically, the second track A132 includes a second channel A1323, which has a strip-shaped structure, and the first channel A1313 and the second channel A1323 are connected at their intersection. Specifically, the sliding component A143 includes a slider A1432, which is connected to the first positioning component A110 and is capable of rotating within the first channel A1313 and sliding within the second channel A1323. More specifically, in this embodiment, the first channel A1313 and the second channel A1323 can be considered as groove structures provided on the upper surface of the second top cover A121.

[0264] See also Figure 39 and Figure 40 In one embodiment, the length L1 and width W1 of slider A1432 are both less than or equal to the diameter D of the first channel A1313, allowing slider A1432 to rotate within the first channel A1313. The length L1 of slider A1432 is greater than the width W2 of the second channel A1323, and the width W1 of slider A1432 is less than or equal to the width W2 of the second channel A1323, allowing slider A1432 to slide within the second channel A1323 while restricting rotation within the second channel A1323. Thus, the orientation of the first positioning component A110 relative to the second positioning component A120 can be changed by the rotation of slider A1432 within the first channel A1313. When the first positioning component A110 is oriented toward the extension direction of the second channel A1323, the slider A1432 can be driven to move from the first channel A1313 into the second channel A1323, thereby changing the setting position of the first positioning component A110 relative to the second positioning component A120.

[0265] Specifically, in this embodiment, the second channel A1323 is divided into a third track segment A1321 and a fourth track segment A1322 by the first channel A1313, and the third track segment A1321 and the fourth track segment A1322 are respectively connected to the first channel A1313. The third track segment A1321 extends from the first channel A1313 towards the second direction F2, and the fourth track segment A1322 extends from the first channel A1313 towards the fourth direction F4. When the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2 or the fourth direction F4, the length direction of the slider A1432 is parallel to the second direction F2.

[0266] See Figure 39 and Figure 40 When slider A1432 is located within the first channel A1313, slider A1432 can rotate within the first channel A1313. This allows the first positioning component A110 to rotate freely relative to the second positioning component A120. For example, the first positioning component A110 can rotate relative to the second positioning component A120 to any one of the first direction F1, the second direction F2, the third direction F3, and the fourth direction F4. In this embodiment, since the third track segment A1321 extends from the first channel A1313 towards the second direction F2, and the fourth track segment A1322 extends from the first channel A1313 towards the fourth direction F4, when the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2 or the fourth direction F4, slider A1432 can be driven to move from the first channel A1313 towards the third track segment A1321 or the fourth track segment A1322 by pushing or pulling the first positioning component A110. Specifically, for example, when the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2, the first positioning component A110 can be moved inward away from the second direction F2 by directly pushing the vehicle body A200, so that the slider A1432 enters the fourth track segment A1322. In this way, when the vehicle body A200 is connected to the first positioning component A110, the distance between the front end of the vehicle body A200 and the left door can be increased (for comparison). Figure 41 and Figure 42When the vehicle body A200 rotates relative to the second positioning component A110 to face the second direction F2, it prevents the front end of the vehicle body A200 from hitting the left-side door. Furthermore, when a child is seated in the side-mounted vehicle body A200, there is ample space for their feet. Alternatively, when the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2, the vehicle body A200 can be moved along the second direction F2 and protrude to the left by directly pulling it. This reduces the distance between the front end of the vehicle body A200 and the left-side door when the vehicle body A200 is connected to the first positioning component A110, making it easier for the user to remove or place a child inside the vehicle body A200.

[0267] See Figure 39 , Figure 43 as well as Figure 44 A second embodiment of the second aspect of this utility model provides a positioning component A100, which can be considered a variation of the positioning component A100 in the second embodiment of the second aspect. The main difference lies in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following mainly describes the differences between this embodiment and the second embodiment of the second aspect described above.

[0268] In this embodiment, as Figure 43As shown, the first track A131 includes a first channel A1313 and a first groove A1314, and the second track A132 includes a second channel A1323 and a second groove A1324. The structures of the first channel A1313 and the second channel A1323 are similar to those in the ninth embodiment, except that both the first channel A1313 and the second channel A1323 are located on the lower surface of the second top cover A121, i.e., on the side of the second top cover A121 facing the second mounting cavity A123. The first groove A1314 is located on the second top cover A121 and inside the first channel A1313, and the second groove A1324 is located on the second top cover A121 and inside the second channel A1323. The second groove A1324 communicates with the first groove A1314 and extends along the extension direction of the second channel A1323, i.e., along the second direction F2 or the fourth direction F4. It should be noted that both the first slide groove A1314 and the second slide groove A1324 are through-slot structures. Specifically, the sliding assembly A143 includes a slider A1432 and a sliding rod A1431. The sliding assembly A143 is connected to the first positioning assembly A110 via the sliding rod A1431. The sliding rod A1431 passes through the first slide groove A1314 or the second slide groove A1324 to connect with the slider A1432, so that the sliding assembly A143 can rotate within the first track A131 and move within the second track A132 via the slider A1432. It should be noted that the width of the slider A1432 is greater than the width of the first slide groove A1314 and the diameter of the second slide groove A1324 (see...). Figure 43 and Figure 44 In this way, the slider A1432 can be confined within the second mounting cavity A123, preventing the first positioning component A110 from disengaging from the second positioning component A120 when it rotates or slides relative to the second positioning component A120.

[0269] See Figure 39 as well as Figure 45 The third embodiment of the second aspect of this utility model provides a positioning component A100, which can be regarded as a variation of the positioning component A100 in the ninth embodiment. The main difference lies in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following mainly describes the differences between this embodiment and the first embodiment of the second aspect described above.

[0270] In this embodiment, as Figure 45As shown, the first track A131 includes a first channel A1313, and the second track A132 includes a second channel A1323, with the second channel A1323 having a strip-shaped structure. Both the first channel A1313 and the second channel A1323 are located on the upper surface of the second top cover A121. The difference is that the first channel A1313 has a ring-shaped structure, and the second channel A1323 passes through the first channel A1313 and is connected at the intersection. The sliding component A143 includes two sliders A1432, both of which are connected to and opposite to the first positioning component A110. The two sliders A1432 can slide synchronously in the first channel A1313, that is, the two sliders A1432 can rotate synchronously along the first channel A1313, so that the first positioning component A110 rotates relative to the second positioning component A120. The two sliders A1432 can also slide synchronously in the second channel A1323, so that the first positioning component A110 slides relative to the second positioning component A120.

[0271] Specifically, in this embodiment, the distance H1 between the sidewalls of the two sliders A1432 toward the center of the first channel A1313 is greater than or equal to the inner diameter D1 of the first channel A1313, so as to allow the two sliders A1432 to move synchronously within the first channel A1313, thereby allowing the first positioning component A110 to rotate relative to the second positioning component A120. More specifically, the distance H1 (i.e., the inner spacing) between the sidewalls of the two sliders A1432 toward the center of the first channel A1313 is greater than the width W2 of the second channel A1323, so as to allow the sliders A1432 to slide within the second channel A1323 while restricting their rotation within the second channel A1323.

[0272] See also Figure 45 Specifically, in this embodiment, the second channel A1323 is divided by the first channel A1313 to form a third track segment A1321, a fifth track segment A1325, and a fourth track segment A1322 arranged sequentially. The first channel A1313 is divided by the second channel A1323 to form a first arc segment A1315 and a second arc segment A1316. The first end of the first arc segment A1315 and the first end of the second arc segment A1316 are both connected to the first end of the fifth track segment A1325 and the third track segment A1321, and the second end of the first arc segment A1315 and the second end of the second arc segment A1316 are both connected to the second end of the fifth track segment A1325 and the fourth track segment A1322. In this way, the two sliders A1432 can rotate simultaneously within the first channel A1313 to change the orientation of the first positioning component A110 relative to the second positioning component A120, and can also move simultaneously from the first channel A1313 into the second channel A1323 to change the position of the first positioning component A110 relative to the second positioning component A120.

[0273] See Figure 39 as well as Figure 46 The fourth embodiment of the second aspect of this utility model provides a positioning component A100, which can be regarded as a variation of the positioning component A100 in the third embodiment of the second aspect. The main difference lies in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following mainly describes the differences between this embodiment and the third embodiment of the second aspect described above.

[0274] In this embodiment, as Figure 46 As shown, the first track A131 includes a first channel A1313 and a first groove A1314, and the second track A132 includes a second channel A1323 and a second groove A1324. The structures of the first channel A1313 and the second channel A1323 are described in the eleventh embodiment, except that both the first channel A1313 and the second channel A1323 are located on the lower surface of the second top cover A121. Specifically, the first groove A1314 is located on the second top cover A121 and inside the first channel A1313, thus the first groove A1314 can be considered an annular structure. The second groove A1324 is located on the second top cover A121 and inside the second channel A1323. The second groove A1324 communicates with the first groove A1314 and extends along the extension direction of the second channel A1323, i.e., along the second direction F2 or the fourth direction F4. It should be noted that both the first slide groove A1314 and the second slide groove A1324 are through-slot structures. More specifically, the sliding assembly A143 also includes two sliding rods A1431 (see...). Figure 39 Both sliding rods A1431 are connected to the first positioning component A110 and pass through the first slide groove A1314 or the second slide groove A1324 before connecting to the two sliders A1432 respectively. It should be noted that the width of slider A1432 is greater than the width of the first slide groove A1314 and the second slide groove A1324 (see...). Figure 46 In this way, the slider A1432 can be confined within the second mounting cavity A123, preventing the first positioning component A110 from disengaging from the second positioning component A120 when it rotates or slides relative to the second positioning component A120.

[0275] See Figure 39 as well as Figure 47 The fifth embodiment of the second aspect of this utility model provides a positioning component A100, which can be regarded as a variation of the positioning component A100 in the fourth embodiment of the second aspect. The main difference lies in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following mainly describes the differences between this embodiment and the fourth embodiment of the second aspect described above.

[0276] In this embodiment, as Figure 47 As shown, the first track A131 includes only the first groove A1314, which has a ring-shaped structure. The second track A132 includes only the second groove A1324, which has a strip-shaped structure. The first groove A1314 and the second groove A1324 are connected at their intersection. Specifically, the second groove A1324 is divided by the first groove A1314 to form a third track segment A1321, a fifth track segment A1325, and a fourth track segment A1322 arranged in sequence. The first groove A1314 is divided by the second groove A1324 to form a first arc segment A1315 and a second arc segment A1316. The first end of the first arc segment A1315 and the first end of the second arc segment A1316 are both connected to the first end of the fifth rail segment A1325 and the third rail segment A1321, respectively. The second end of the first arc segment A1315 and the second end of the second arc segment A1316 are both connected to the second end of the fifth rail segment A1325 and the fourth rail segment A1322. More specifically, as... Figure 39 and Figure 47 As shown, the sliding component A143 includes two sliders A1432 and two sliding rods A1431. Both sliding rods A1431 are connected to and opposite to the first positioning component A110. The two sliding rods A1431 pass through a first groove A1314 or a second groove A1324 and are connected to the two sliders A1432 respectively. The two sliding rods A1431 can simultaneously slide within the first groove A1314, causing the first positioning component A110 to rotate relative to the second positioning component A120. The two sliders A1432 can also slide synchronously within the second groove A1324, causing the first positioning component A110 to slide relative to the second positioning component A120 along a second direction F2 or a fourth direction F4.

[0277] As described above, in the first to fifth embodiments of the second aspect, the first positioning component A110 shown in each embodiment is capable of rotating and sliding relative to the second positioning component A120. It should be noted that in each embodiment of this aspect, when the first positioning component A110 protrudes relative to the second positioning component A120 towards one side (e.g., the left or right side), it means that the first positioning component A110 is displaced to one side relative to the geometric center of the second positioning component A120. The vehicle body A200 can also be considered to have undergone lateral displacement relative to the second positioning component A120, so that the front end of the vehicle body A200 (the position where the child's feet are placed) is closer to that side door. When the first positioning component A110 retracts relative to the second positioning component A120 toward one side (such as the left or right side) of the second positioning component A120, the geometric center of the first positioning component A110 relative to the second positioning component A120 is displaced to the opposite side. The vehicle body A200 will also retract laterally relative to the second positioning component A120 so that the front end of the vehicle body A200 (the position where the child's feet are placed) moves away from the door on that side.

[0278] An embodiment of the third aspect of this utility model provides a carrier A1000, which includes a carrier body A200 and a positioning component A100 provided in some embodiments of this utility model. The carrier body A200 can be fixedly mounted on the positioning component A100; alternatively, the carrier body A200 can be detachably mounted on the positioning component A100. In the carrier A1000 provided in this embodiment, the carrier body A200 is the same as the carrier body A200 provided in the preceding embodiments. The positioning component A100 is similar to the positioning component A100 in the preceding embodiments, including components such as a first positioning component A110 and a second positioning component A120. The first positioning component A110 is rotatable relative to the second positioning component A120, allowing it to rotate in various directions relative to the second positioning component A120, such as a first direction F1, a second direction F2, a third direction F3, or a fourth direction F4. Specifically, the principle of rotation of the first positioning component A110 relative to the second positioning component A120 can be referred to any of the above embodiments. It should be noted that, in this embodiment, the first positioning component A110 can rotate and slide relative to the second positioning component A120; or, in this embodiment, the first positioning component A110 can only rotate relative to the second positioning component A120, and is limited to sliding relative to the second positioning component A120.

[0279] See Figure 1 and Figure 48In this embodiment, the first top cover A111 of the first positioning component A110 is provided with a slot A114. When the carrier body A200 is connected to the first positioning component A110, the slot A114 is used to accommodate the engaging member A210 on the positioning component A100. More specifically, the slot A114 has a through hole inside, which connects to the first mounting cavity (the cavity inside the first positioning component A110, i.e., the chamber formed by the first top cover A111 and the first bottom cover A112 being connected vertically). The engaging hook A151 is rotatably disposed in the first mounting cavity and can extend into the slot A114 through the through hole. When the engaging hook A151 is in the locked position, the engaging hook A151 extends at least partially into the slot A114 to block the opening of the slot A114, thereby confining the engaging member A210 within the slot A114. When the locking hook A151 is in the unlocked position, the locking hook A151 retracts from the locking groove A114, so that the opening of the groove A114 is opened, and the locking piece A210 can be disengaged from the groove A114.

[0280] In one embodiment, the first connecting mechanism A150 may include two sets of engaging hooks A151, and the carrier body A200 is provided with two engaging components A210 (see...). Figure 1 and Figure 48Two locking components A210 are spaced apart along the Q1 or Q3 direction of the carrier body A200. Correspondingly, two sets of locking hooks A151 are spaced apart along the Q1 (or Q3) direction on the first positioning component A110. Thus, the two sets of locking hooks A151 can be used to lock or unlock the corresponding locking component A210. When the first positioning component A110 rotates relative to the second positioning component A120 to face the first direction F1 or the third direction F3, both the Q1 and Q3 directions are parallel to the first direction F1 or the third direction F3. When the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2 or the fourth direction F4, both the Q1 and Q3 directions are parallel to the second direction F2 or the fourth direction F4. Specifically, when both locking components A210 are simultaneously locked by two sets of locking hooks A151, the stability and reliability of the vehicle body A200 mounted on the first positioning component A110 can be improved, preventing the vehicle body A200 from moving or rotating arbitrarily relative to the first positioning component A110. Of course, in other embodiments, the first connecting mechanism A150 may also include a set of locking hooks A151, and the vehicle body A200 may have one locking component A210. It should be noted that in this embodiment, a set of locking hooks A151 may include one, two, or more locking hooks A151. When a set of locking hooks A151 includes multiple locking hooks A151, the multiple locking hooks A151 are spaced apart along the Q2 direction (or Q4 direction). It should be noted that when the first positioning component A110 is oriented relative to the second positioning component A120 towards the first direction F1 or the third direction F3, both the Q2 and Q4 directions are parallel to the second direction F2 or the fourth direction F4 (see...). Figure 1 and Figure 2 When the first positioning component A110 is oriented relative to the second positioning component A120 in the second direction F2 or the fourth direction F4, both directions Q2 and Q4 are parallel to the first direction F1 or the third direction F3 (see...). Figure 49 It should be noted that direction Q1 refers to the forward direction within the front-rear direction of the first positioning component A110 or the vehicle body A200; direction Q2 refers to the backward direction within the front-rear direction of the first positioning component A110 or the vehicle body A200; direction Q3 refers to the left direction within the left-right direction of the first positioning component A110 or the vehicle body A200; and direction Q4 refers to the right direction within the left-right direction of the first positioning component A110 or the vehicle body A200. Directions Q1 and Q3 are parallel and opposite, directions Q2 and Q4 are parallel and opposite, and directions Q1 and Q2 intersect. Specifically, direction Q1 is perpendicular to direction Q2.

[0281] In other embodiments of the third aspect, the vehicle body A200 may be provided with at least two engaging members A210, which are spaced apart along the Q1 or Q3 direction of the vehicle body A200. The first connecting mechanism A150 may include at least three sets of engaging hooks A151, which are spaced apart along the Q1 or Q3 direction on the first positioning component A110 (see...). Figure 49 When all sets of engaging hooks A151 are in the locked position, each set of engaging hooks A151 is used to engage and lock with each engaging component A210 on the vehicle body A200. Specifically, at least two engaging components A210 can be selectively locked to any two adjacent sets of engaging hooks A151, so that the vehicle body A200 has a first use state and a second use state relative to the positioning assembly A100.

[0282] See Figure 48 and Figure 49 Specifically, in this embodiment, the principle that the two locking parts A210 can be selectively locked to any two adjacent sets of locking hooks A151 can be simply explained by taking the example that the vehicle body A200 is provided with two locking parts A210 and the first connecting mechanism A150 includes three sets of locking hooks A151, so that the vehicle body A200 has a first use state and a second use state relative to the positioning component A100.

[0283] To facilitate understanding of the engagement relationship between the two engaging components A210 and the three sets of engaging hooks A151, the engaging component A210 closer to the front end of the vehicle body A200 is defined as the first engaging component A2101, and the engaging component A210 closer to the rear end of the vehicle body A200 is defined as the second engaging component A2102. Taking the case where the first positioning component A110 rotates relative to the second positioning component A120 to face the first direction F1 as a reference, the three sets of engaging hooks A151 on the first positioning component A110 are sequentially referred to as the first set of engaging hooks A1511, the second set of engaging hooks A1512, and the third set of engaging hooks A1513 along the Q3 direction of the first positioning component A110 (see [reference]). Figure 49 In other words, when the first positioning component A110 faces the first direction F1, the first set of engaging hooks A1511 is located at the foremost position along the first direction F1 (or Q1 direction), that is, closer to the support leg A162, and the third set of engaging hooks A1513 is located at the rearmost position along the first direction F1 (or Q1 direction). When the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2, the first set of engaging hooks A1511 can be considered as being closest to the left door, and the third set of engaging hooks A1513 can be considered as being closest to the right door. See also Figures 48 to 50In one embodiment, when the vehicle body A200 is connected to the first positioning component A110 via the first connecting mechanism A150, the vehicle body A200 and the first positioning component A110 can engage in the same direction, meaning that the orientation of the vehicle body A200 relative to the positioning component A100 is the same as the orientation of the first positioning component A110 relative to the second positioning component A120. For example, the first positioning component A110 and the vehicle body A200 are oriented in the same direction as a first direction F1, a second direction F2, a third direction F3, or a fourth direction F4. Therefore, when the vehicle body A200 and the first positioning component A110 engage in the same direction, the first set of engaging hooks A1511 can be considered as being closer to the front end of the vehicle body A200, and the third set of engaging hooks A1513 can be considered as being closer to the rear end of the vehicle body A200.

[0284] Specifically, when the vehicle body A200 is in the first use state relative to the positioning component A100, the two locking members A210 (i.e., the first locking member A2101 and the second locking member A2102) are respectively locked to the first two sets of locking hooks A151 (i.e., the first set of locking hooks A1511 and the second set of locking hooks A1512) located near the front end of the first positioning component A110. For example, when the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2 (see... Figure 49 When the vehicle body A200 is oriented in the second direction F2 (see...), Figure 50 In one scenario, the first engaging component A2101 is locked to the first set of engaging hooks A1511, and the second engaging component A2102 is locked to the second set of engaging hooks A1512. At this time, the front end of the vehicle body A200 protrudes outward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the second direction F2) (not shown in the figure). Alternatively, if the first positioning component A110 rotates relative to the second positioning component A120 to face the fourth direction F4 (not shown), and the vehicle body A200 faces the fourth direction F4, the first engaging component A2101 is locked to the first set of engaging hooks A1511, and the second engaging component A2102 is locked to the second set of engaging hooks A1512. At this time, the front end of the vehicle body A200 protrudes outward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the fourth direction F4) (not shown in the figure). In this way, when the vehicle body A200 rotates with the first positioning component A110 relative to the second positioning component A120 to the second direction F2 or the fourth direction F4, the distance between the front end of the vehicle body A200 and the left or right door can be reduced, thereby making it convenient for the user to take the child out of the vehicle body A200 or put the child into the vehicle body A200.

[0285] When the vehicle body A200 is in the second use state relative to the positioning component A100, the two locking members A210 (i.e., the first locking member A2101 and the second locking member A2102) are respectively locked to the latter two sets of locking hooks A151 (i.e., the second set of locking hooks A1512 and the third set of locking hooks A1513) located near the rear end of the first positioning component A110. For example, when the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2 (see... Figure 49 When the front end of the vehicle body A200 is facing the second direction F2 (see...), Figure 50 The first locking component A2101 is locked to the second locking hook A1512, and the second locking component A2102 is locked to the third locking hook A1513 (see...). Figure 49 and Figure 51 At this time, the front end of the vehicle body A200 is recessed inward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the second direction F2) (see...). Figure 50 and Figure 51 For example, when the first positioning component A110 rotates relative to the second positioning component A120 to face the fourth direction F4 (not shown), and the vehicle body A200 faces the fourth direction F4, the first engaging component A2101 is locked to the second set of engaging hooks A1512, and the second engaging component A2102 is locked to the third set of engaging hooks A1513. At this time, the front end of the vehicle body A200 retracts inward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the fourth direction F4). For example, when the first positioning component A110 rotates relative to the second positioning component A120 to face a third direction F3, and the vehicle body A200 faces a third direction F3, the first engaging component A2101 is locked to the second set of engaging hooks A1512, and the second engaging component A2102 is locked to the third set of engaging hooks A1513. At this time, the front end of the vehicle body A200 retracts inward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the third direction F3) (see...). Figure 52 and Figure 53 Thus, when the vehicle body A200 rotates with the first positioning component A110 relative to the second positioning component A120 to the second direction F2 (see...), Figure 50 and Figure 51 When the vehicle body A200 is rotated to the third direction F3 with the first positioning component A110 relative to the second positioning component A120 (see...), the distance between the front end of the vehicle body A200 and the left or right door can be increased to prevent collision with the left or right door; in addition, it provides more space for children to place their feet when sitting sideways. Similarly, when the vehicle body A200 rotates to the third direction F3 with the first positioning component A110 relative to the second positioning component A120 (see...), the distance between the front end of the vehicle body A200 and the left or right door can be increased to prevent collision with the left or right door; in addition, it provides more space for children to place their feet when sitting sideways. Figure 52This increases the distance between the front of the vehicle body A200 and the back of the car seat, providing more space for children to place their feet when they are sitting rear-facing.

[0286] Optionally, in other embodiments, when the vehicle body A200 is connected to the first positioning component A110 via the first connecting mechanism A150, the vehicle body A200 and the first positioning component A110 can also engage in reverse, that is, the orientation of the vehicle body A200 relative to the positioning component A100 is opposite to the orientation of the first positioning component A110 relative to the second positioning component A120. For example, when the first positioning component A110 is oriented in the first direction F1, the vehicle body A200 is oriented in the third direction F3; or, when the first positioning component A110 is oriented in the second direction F2, the vehicle body A200 is oriented in the fourth direction F4. It should be noted that in this embodiment, when the vehicle body A200 is connected to the first positioning component A110, the vehicle body A200 also has a first usage state and a second usage state. The difference from the above embodiment is that when the vehicle body A200 and the first positioning component A110 are engaged in reverse, the first set of engaging hooks A1511 is closer to the rear end of the vehicle body A200, and the third set of engaging hooks A1513 is closer to the front end of the vehicle body A200. When the vehicle body A200 is in the first use state relative to the first positioning component A110, the two engaging pieces A210 are respectively locked to the latter two sets of engaging hooks A151 (i.e., the second set of engaging hooks A1512 and the third set of engaging hooks A1513) located near the rear end of the first positioning component A110; when the vehicle body A200 is in the second use state relative to the positioning component A100, the two engaging pieces A210 are respectively locked to the first two sets of engaging hooks A151 (i.e., the first set of engaging hooks A1511 and the third set of engaging hooks) located near the front end of the first positioning component A110. Other aspects are similar to the above embodiment and will not be described again.

[0287] Optionally, in another embodiment, the principle that two of the locking members A210 can be selectively locked to any two adjacent sets of locking hooks A151 can be simply explained by taking the vehicle body A200 having three locking members A210 and the first connecting mechanism A150 including three sets of locking hooks A151 as an example, so that the vehicle body A200 has a first use state and a second use state relative to the positioning component A100.

[0288] To better understand the engagement relationship between the three locking components A210 and the three sets of locking hooks A151, please refer to... Figure 53 and Figure 54The first locking component A2101 is defined as the locking component A210 closest to the front end of the vehicle body A200, the second locking component A210 is defined as the locking component A2102 closest to the rear end of the vehicle body A200, and the third locking component A210 is defined as the locking component A2103 located between the two locking components A210. Similarly, taking the case where the first positioning component A110 rotates relative to the second positioning component A120 to face the first direction F1 as a reference, the three sets of engaging hooks A151 on the first positioning component A110 are sequentially referred to as the first set of engaging hooks A1511, the second set of engaging hooks A1512, and the third set of engaging hooks A1513 along the Q3 direction; in other words, when the first positioning component A110 faces the first direction F1, the first set of engaging hooks A1511 is located at the foremost end along the first direction F1 (or Q1 direction), that is, closer to the support leg A162, and the third set of engaging hooks A1513 is located at the rearmost end along the first direction F1 (or Q1 direction). In this embodiment, the vehicle body A200 engages with the first positioning component A110 in the same direction. It should be noted that when the vehicle body A200 and the first positioning component A110 engage in the same direction, the first set of engaging hooks A1511 can be regarded as being closer to the front end of the vehicle body A200, and the third set of engaging hooks A1513 can be regarded as being closer to the rear end of the vehicle body A200.

[0289] When the vehicle body A200 is in the first use state relative to the positioning component A100, the two adjacent first locking parts A210 (i.e., the first locking part A2101 and the third locking part A2103) or the two adjacent last locking parts A210 (i.e., the second locking part A2102 and the third locking part A2103) are respectively locked to the two sets of locking hooks A151 (i.e., the first set of locking hooks A1511 and the second set of locking hooks A1512) provided near the front end of the first positioning component A110. For example, when the first positioning component A110 is oriented towards a third direction F3 relative to the second positioning component A120, and the front end of the vehicle body A200 is oriented towards a third direction F3, the first engaging component A2101 is locked to the first set of engaging hooks A1511, and the third engaging component A2103 is locked to the second set of engaging hooks A1512. The second engaging component A2102 can be locked to the third set of engaging hooks A1513 or is in a free state (i.e., not locked by any set of engaging hooks A151). At this time, the front end of the vehicle body A200 protrudes outward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., towards a third direction F3) (see...). Figure 54For example, when the first positioning component A110 is oriented towards a third direction F3 relative to the second positioning component A120, and the front end of the vehicle body A200 is oriented towards a third direction F3, the third locking component A2103 is locked to the first set of locking hooks A1511, and the second locking component A2102 is locked to the second set of locking hooks A1512. At this time, the front end of the vehicle body A200 also protrudes outward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the third direction F3). For example, when the first positioning component A110 is oriented towards the second direction F2 or the fourth direction F4 relative to the second positioning component A120, and the vehicle body A200 is installed in the same direction as the first positioning component A110, the two adjacent locking parts A210 (i.e., the first locking part A2101 and the third locking part A2103, or the third locking part A2103 and the second locking part A2102) are respectively locked to the first two sets of locking hooks A151 (i.e., the first set of locking hooks A1511 and the second set of locking hooks A1512) provided near the front end of the first positioning component A110, and the front end of the vehicle body A200 protrudes outward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the second direction F2 or the fourth direction F4) (not shown in the figure).

[0290] When the vehicle body A200 is in the second usage state relative to the positioning component A100, the two adjacent first engaging parts A210 (i.e., the first engaging part A2101 and the third engaging part A2103) are respectively locked to the two sets of engaging hooks A151 (i.e., the second set of engaging hooks A1512 and the third set of engaging hooks A1513) located near the rear end of the first positioning component A110. For example, when the first positioning component A110 is facing a third direction F3 relative to the second positioning component A120, and the vehicle body A200 is facing a third direction F3, the first engaging part A2101 is locked to the second set of engaging hooks A1512, and the third engaging part A2103 is locked to the third set of engaging hooks A1513. The second engaging part A2102 is in a free state, that is, it is not locked by any set of engaging hooks A151, and the first set of engaging hooks A1511 is not engaged with any engaging part A210. At this time, the front end of the vehicle body A200 is recessed inward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., third direction F3) (see...). Figure 53For example, when the first positioning component A110 is oriented relative to the second positioning component A120 in the second direction F2 or the fourth direction F4, and the front end of the vehicle body A200 is oriented in the second direction F2 or the fourth direction F4, the first engaging member A2101 is locked to the second set of engaging hooks A1512, and the third engaging member A210 is locked to the third set of engaging hooks A1513. The second engaging member A210 is in a free state, i.e., not locked by any set of engaging hooks A151. At this time, the front end of the vehicle body A200 retracts inward relative to the first positioning component A110 along the orientation of the vehicle body A200 (i.e., the second direction F2 or the fourth direction F4) (see...). Figure 50 and Figure 51 In this way, the user can adjust the distance between the front end of the vehicle body A200 and the interior wall of the car (such as the door, seat back, etc.) by changing the corresponding engagement relationship between each engagement piece A210 in the vehicle body A200 and each set of engagement hooks A151 on the first positioning component A110.

[0291] It should be noted that the first connecting mechanism A150 described above can be applied to any of the preceding embodiments.

[0292] Please see Figures 55 to 57 , Figures 55 to 57 A perspective view of a carrier B1000 according to a fourth aspect of the present invention is schematically shown. The carrier B1000 includes a carrier body B300 and a positioning component B100 according to another embodiment of the present invention. The carrier body B300 and the positioning component B100 will be described in conjunction with the following description of the carrier B1000.

[0293] Figures 58 to 60 The structure of a positioning component B100 in one embodiment of the fourth aspect of the present invention is generally shown. This positioning component B100 is used to position the carrier body B300 (see...) Figures 55 to 57 It is installed onto a car seat (not shown). In one embodiment, the positioning component B100 may include a first positioning component B110 and a second positioning component B120. Figure 61 and Figure 62 The structure of the second positioning component B120 in the positioning component B100 in one embodiment of the present invention is shown. Figure 63This illustrates the structure of the first positioning component B110 in the positioning component B100 according to an embodiment of the present invention. One of the first positioning component B110 and the second positioning component B120 is provided with a first track B131 and a second track B132 that are intersected. The other of the first positioning component B110 and the second positioning component B120 is provided with a sliding component that slides along the first track B131 and the second track B132. Specifically, the sliding component includes a first sliding member B141 and a second sliding member B142. For example, as... Figures 61 to 63 As shown, the first positioning component B110 is provided with a first sliding member B141 and a second sliding member B142, and the second positioning component B120 is provided with a first track B131 and a second track B132. Alternatively, in other embodiments not shown, the first positioning component B110 is provided with a first track B131 and a second track B132, and the second positioning component B120 is provided with a first sliding member B141 and a second sliding member B142. The first sliding member B141 slides along either the first track B131 or the second track B132, and the second sliding member B142 slides along the other of either the first track B131 or the second track B132. For example, as... Figure 62 and Figure 63 As shown, the first slider B141 slides along the second track B132, and the second slider B142 slides along the first track B131. Alternatively, in other embodiments not shown, the first slider B141 slides along the first track B131, and the second slider B142 slides along the second track B132. Thus, by sliding the first slider B141 along either the first track B131 or the second track B132, and the second slider B142 along the other of the first track B131 or the second track B132, the first positioning component B110 can be displaced simultaneously with the rotation of the second positioning component B120.

[0294] In one embodiment, such as Figure 55 and Figure 58 As shown, the first positioning component B110 is used to connect to the vehicle body B300, and the second positioning component B120 is used to connect to the car seat. Specifically, as... Figures 57 to 59As shown, the first positioning component B110 is provided with a first connecting mechanism B170 (e.g., a locking hook), which is mainly used to connect with a locking member (not shown) at the bottom of the vehicle body B300. The second positioning component B120 is provided with a seat connecting mechanism B180 (e.g., an ISOFIX connector) and a support leg B190. The seat connecting mechanism B180 is mainly used to fix the second positioning component B120 to the car seat, and the support leg B190 is mainly used to rest against the floor inside the vehicle. Thus, when the positioning component B100 is installed on the car seat and the vehicle body B300 is installed on the positioning component B100, the orientation of the vehicle body B300 can be changed by rotating the first positioning component B110, allowing the vehicle body B300 to have different usage modes. In some embodiments, the orientation of the vehicle body B300 depends on the extension direction of the first track B131 and the second track B132. For example, when the first track B131 extends along the first direction F1 or the third direction F3, and the second track B132 extends along the second direction F2 or the fourth direction F4, the vehicle body B300 has a usage mode oriented towards the first direction F1 or the third direction F3, and a usage mode oriented towards the second direction F2 or the fourth direction F4.

[0295] See Figure 61 and Figure 62In one embodiment, the intersection point of the first track B131 and the second track B132 is defined as the intersection center B133. Both the first track B131 and the second track B132 are divided by the intersection center B133 to form two track segments. For example, the first track B131 is divided by the intersection center B133 to form a first track segment B1311 and a second track segment B1312, and the second track B132 is divided by the intersection center B133 to form a third track segment B1321 and a fourth track segment B1322. Specifically, the first track segment B1311 extends from the intersection center B133 in a first direction F1, the second track segment B1312 extends from the intersection center B133 in a third direction F3, the third track segment B1321 extends from the intersection center B133 in a second direction F2, and the fourth track segment B1322 extends from the intersection center B133 in a fourth direction F4. In this configuration, the third direction F3 is parallel to the first direction F1 but faces the opposite direction, and the fourth direction F4 is parallel to the second direction F2 but faces the opposite direction. Both the first direction F1 and the third direction F3 intersect the second direction F2 and the fourth direction F4. Specifically, both the first direction F1 and the third direction F3 are perpendicular to the second direction F2 and the fourth direction F4. When the positioning component B100 is fixed to the car seat, the first direction F1 is the front of the car during normal driving, i.e., the direction of the front of the car; the second direction F2 is the left side of the car during normal driving, i.e., the direction of the left door; the third direction F3 is the rear of the car during normal driving, i.e., the direction facing the rear of the car; and the fourth direction F4 can be considered the right side of the car during normal driving, i.e., the direction of the right door. In this way, the vehicle body B300 can rotate with the first positioning component B110 relative to the second positioning component B120 to face the front, rear, left, or right of the car, giving the vehicle body B300 a forward mode, a rearward mode, and a side mode.

[0296] In this embodiment, the first positioning component B110 has a front end, a rear end, a left end, and a right end. To clearly understand the various ends of the first positioning component B110, taking the vehicle body B300 mounted on the first positioning component B110 as an example, the front-back direction of the vehicle body B300 is parallel to the front-back direction of the first positioning component B110, and the left-right direction of the vehicle body B300 is parallel to the left-right direction of the first positioning component B110. Specifically, when an infant or child is sitting inside the vehicle body B300, the front end of the first positioning component B110 is closer to the infant's or child's feet than the rear end; conversely, the rear end of the first positioning component B110 is closer to the infant's or child's head than the front end; the left end of the first positioning component B110 is closer to the infant's or child's left hand than the right end; and the right end of the first positioning component B110 is closer to the infant's or child's right hand than the left end. When the first positioning component A110 faces a certain direction, it means that the vehicle body A200 also faces the same direction; simultaneously, the child riding inside the vehicle body A200 also faces the same direction. To visually understand the front-back and left-right directions of the vehicle body B300 and the first positioning component B110, arrows Q1 and Q3 are used to schematically indicate the "front" and "back" directions, respectively, and arrows Q2 and Q4 are used to schematically indicate the "left" and "right" directions, respectively. Specifically, direction Q1 is parallel to and opposite to direction Q3, direction Q2 is parallel to and opposite to direction Q4, and direction Q1 and direction Q2 intersect. Specifically, direction Q1 is perpendicular to direction Q2. These directional terms are used only to make the description of the embodiments of this utility model clearer and are not intended to unduly limit the scope of protection of this utility model. Therefore, the statement mentioned above that "the vehicle body B300 can rotate with the first positioning component B110 relative to the second positioning component B120 to face the front, rear, left or right of the vehicle" means that the front ends of the vehicle body B300 and the first positioning component B110 can face the front, rear, left or right of the vehicle.

[0297] See Figures 61 to 63In one embodiment, the distance R1 between the intersection center B133 and the two ends of the first track B131 is greater than or equal to the distance R3 between the first slider B141 and the second slider B142, i.e., R1 ≥ R3; the distance R2 between the intersection center B133 and the two ends of the second track B132 is greater than or equal to the distance R3 between the first slider B141 and the second slider B142, i.e., R2 ≥ R3. Specifically, in this embodiment, R1 = R2 = R3; in other words, the lengths of the first track segment B1311, the second track segment B1312, the third track segment B1321, and the fourth track segment B1322 are all equal, and the length of each track segment is equal to the distance between the first slider B141 and the second slider B142. Of course, in some other embodiments not shown, some track segments may have equal lengths, while the remaining track segments may have unequal lengths. Alternatively, the lengths of all track segments may be unequal.

[0298] Please continue reading Figures 61 to 63 In this embodiment, taking the second positioning component B120 having a first track B131 and a second track B132 arranged in a cross configuration, and the first positioning component B110 having a first sliding member B141 and a second sliding member B142 spaced apart, with the first sliding member B141 sliding along the second track B132 and the second sliding member B142 sliding along the first track B131 as an example, the structure and position of the first track B131, the second track B132, the first sliding member B141, and the second sliding member B142 are briefly explained, and the principle of the first positioning component B110 rotating and moving relative to the second positioning component B120 is also briefly explained.

[0299] In one embodiment, the first positioning component B110 is generally disk-shaped, the first slider B141 is located at the center of the first positioning component B110, and the second slider B142 is located off-center. Of course, in other embodiments, the first positioning component B110 can be other symmetrical shapes (e.g., ellipse, rectangle, etc.), and the first slider B141 can be located at or off-center from the geometric center of the first positioning component B110; alternatively, the first positioning component B110 can also be asymmetrical, and the location of the first slider B141 can be determined according to...

[0300] Please combine Figure 55 , Figure 62 and Figure 63In some embodiments, when the vehicle body B300 on the first positioning component B110 is oriented towards the first direction F1, the second slider B142 is positioned on the first positioning component B110 behind the first slider B141 along the first direction F1. Specifically, during the process of the first positioning component B110 turning and moving relative to the second positioning component B120, when the first slider B141 is located at the intersection center B133 and the second slider B142 is located at the second track segment B1312, the first positioning component B110 is oriented towards the first direction F1 relative to the second positioning component B120. At this time, the vehicle body B300 mounted on the first positioning component B110 can be considered to be facing the front of the vehicle. When the first slider B141 is located at the intersection center B133 and the second slider B142 is located at the first track segment B1311, the first positioning component B110 faces a third direction F3 (i.e., away from the first direction F1) relative to the second positioning component B120. In this case, the vehicle body B300 mounted on the first positioning component B110 can be considered to face the rear of the vehicle. When the second slider B142 is located at the intersection center B133 and the first slider B141 is located at the third track segment B1321, the first positioning component B110 faces a second direction F2 relative to the second positioning component B120. In this case, the vehicle body B300 mounted on the first positioning component B110 can be considered to face the left side of the vehicle. When the second slider B142 is located at the intersection center B133 and the first slider B141 is located at the fourth track segment B1322, the first positioning component B110 faces the fourth direction F4 relative to the second positioning component B120. At this time, the vehicle body B300 mounted on the first positioning component B110 can be considered to face the right side of the vehicle (i.e., away from the second direction F2). It can be seen that by changing the position of the first slider B141 within the second track B132 and the position of the second slider B142 within the first track B131, the orientation of the vehicle body B300 on the first positioning component B110 can be changed, so that the vehicle body B300 has a forward mode, a rearward mode, and a side mode. In other words, "forward mode" refers to the state in which the front end of the first positioning component B110 or the front end of the vehicle body B300 faces the front of the car, "rearward mode" refers to the state in which the front end of the first positioning component B110 or the front end of the vehicle body B300 faces the rear of the car, and "side mode" refers to the state in which the front end of the first positioning component B110 or the front end of the vehicle body B300 faces the side of the car (i.e., the door).

[0301] The following is combined Figure 55 , Figure 56 , Figures 60 to 63 This paper briefly explains the principle and process of the first positioning component B110 rotating relative to the second positioning component B120 and simultaneously displacing.

[0302] Similarly, for the sake of clarity in the following explanation, the intersection center B133 is regarded as point M or point N', the end of the first track segment B1311 away from the intersection center B133 is regarded as point N”, the end of the second track segment B1312 away from the intersection center B133 is regarded as point N, the end of the third track segment B1321 away from the intersection center B133 is regarded as point M', and the end of the fourth track segment B1322 away from the intersection center B133 is regarded as point M”.

[0303] When the first positioning component B110 is positioned relative to the second positioning component B120 in the first direction F1, the first sliding member B141 is located at the intersection center B133, i.e., point M, and the second sliding member B142 is located at the end of the second track segment B1312 away from the intersection center B133, i.e., point N.

[0304] When the user needs to switch the orientation of the first positioning component B110 relative to the second positioning component B120 from facing the first direction F1 to facing the second direction F2, it is equivalent to changing the orientation of the first positioning component B110 relative to the second positioning component B120 from facing forward to facing left. The user can pull the first positioning component B110 or the vehicle body B300 to the left, and at the same time, the first positioning component B110 tends to rotate counterclockwise. In this way, the first slider B141 can move from point M to point M' within the second track B132, and at the same time, the second slider B142 can move synchronously from point N to point N' within the first track B131. During this process, the first positioning component B110 gradually begins to rotate relative to the second positioning component B120, and can also move laterally (specifically along the left direction) relative to the second positioning component B120. When the first slider B141 moves to M', the second slider B142 is located at point N', i.e., at the intersection center B133. At this time, the first positioning component B110 is oriented towards the second direction F2 relative to the second positioning component B120. It should be noted that the switching process of the first positioning component B110 relative to the second positioning component B120 towards the first direction F1 and the second direction F2 is reversible. That is, the orientation of the first positioning component B110 relative to the second positioning component B120 can switch from towards the first direction F1 to the second direction F2, or from towards the second direction F2 to the first direction F1.

[0305] When the user needs to switch the orientation of the first positioning component B110 relative to the second positioning component B120 from facing the first direction F1 to facing the fourth direction F4, the user can pull the first positioning component B110 or the vehicle body B300 to the right, causing the first positioning component B110 to rotate clockwise. This allows the first slider B141 to move from point M to point M” within the second track B132, while simultaneously causing the second slider B142 to move from point N to point N' within the first track B131. During this process, the first positioning component B110 gradually begins to rotate relative to the second positioning component B120, and can also move laterally (specifically along the right side) relative to the second positioning component B120. When the first slider B141 moves to point M”, the second slider B142 is located at point N', i.e., at the intersection center B133, at which point the first positioning component B110 faces the fourth direction F4 relative to the second positioning component B120. Similarly, the switching process of the first positioning component B110 relative to the second positioning component B120 in the direction of the first direction F1 and the fourth direction F4 is reversible.

[0306] In addition, the user can also switch the first positioning component B110 relative to the second positioning component B120 from facing the second direction F2 or the fourth direction F4 to facing the third direction F3. The following explanation will take the switching of the first positioning component B110 relative to the second positioning component B120 from facing the second direction F2 to facing the third direction F3 as an example. Specifically, the user can pull the first positioning component B110 or the vehicle body B300, causing the first positioning component B110 to rotate counterclockwise. This allows the second slider B142 to move from point N' to point N” within the first track B131, and simultaneously, from point M' to point M within the second track B132. During this process, the first positioning component B110 gradually begins to rotate relative to the second positioning component B120, and its rear end can move relative to the second positioning component B120 in the first direction F1. When the second slider B142 moves to point N”, the first slider B141 is located at point M, i.e., the intersection center B133, at which point the first positioning component B110 is facing the third direction F3 relative to the second positioning component B120. Similarly, the switching process of the first positioning component B110 relative to the second positioning component B120 towards the second direction F2 and the third direction F3 is reversible.

[0307] Furthermore, when the user needs to switch the first positioning component B110 relative to the second positioning component B120 from facing the third direction F3 to facing the fourth direction F4, the user can directly pull the first positioning component B110 or the vehicle body B300, causing the first positioning component B110 to rotate counterclockwise. This allows the first sliding member B141 to move from point M to point M” within the second track B132, and the second sliding member B142 to move synchronously from point N” to point N’ within the first track B131. Similarly, when the user needs to switch the first positioning component B110 relative to the second positioning component B120 from being oriented towards the fourth direction F4 to being oriented towards the first direction F1, the user can directly pull the first positioning component B110 or the carrier body B300, causing the first positioning component B110 to rotate counterclockwise. This allows the second sliding member B142 to move from point N' to point N within the first track B131, and the first sliding member B141 to move synchronously from point M” to point M within the second track B132.

[0308] In some other embodiments, when the carrier body B300 on the first positioning component B110 faces the first direction F1, the position of the second slider B142 on the first positioning component B110 can also be located in front of, to the left of, or to the right of the first slider B141 along the first direction F1. Specifically, when the second slider B142 is located in front of the first slider B141 along the first direction F1, the first positioning component B110 can still rotate and slide relative to the second positioning component B120 simultaneously by the sliding of the first slider B141 within the second track B132. When the second slider B142 is located to the left or right of the first slider B141 along the first direction F1, the first slider B141 will slide within the first slide rail B131, and the second slider B142 will slide within the second slide rail B132. In this way, the first positioning component B110 can rotate relative to the second positioning component B120 while sliding.

[0309] See Figures 61 to 64 In one embodiment, the second positioning component B120 includes a second housing with a second mounting cavity B121 (or may also be referred to as a mounting cavity). Specifically, the second housing includes a second top cover B122 (or may also be referred to as a top cover) and a second bottom cover B123 (or may also be referred to as a bottom cover), the second top cover B122 and the second bottom cover B123 being vertically connected and enclosing to form a second mounting cavity B121. The first sliding member B141 may include a first sliding rod B1411 and a first slider B1412 connected to each other, and the second sliding member B142 may include a second sliding rod B1421 and a second slider B1422 connected to each other. In one embodiment, please refer to... Figure 63 and Figure 64 As shown, the first track B131 may include a first channel B1313 and a first groove B1314, and the second track B132 may include a second channel B1323 and a second groove B1324. Both the first channel B1313 and the second channel B1323 are located on the lower surface of the second top cover B122, facing the second mounting cavity B121. They intersect and communicate with each other, and both the first channel B1313 and the second channel B1323 are connected to the second mounting cavity B121. The first groove B1314 is located inside the first channel B1313, and the second groove B1324 is located inside the second channel B1323. Both the first groove B1314 and the second groove B1324 are through-slot structures. Specifically, when the first slider B141 slides along the second track B132, it can be considered that the first sliding rod B1411 slides within the second groove B1324, while the first slider B1412 slides within the second channel B1323; when the second slider B142 slides along the first track B131, it can be considered that the second sliding rod B1412 slides within the first groove B1314, while the second slider B1413 slides within the first channel B1313. More specifically, as... Figure 64As shown, the width of the first slider B1412 along the first direction F1 or the third direction F3 is greater than the width L2 of the second groove B1324, and the width of the second slider B1422 along the second direction F2 or the fourth direction F4 is greater than the width L3 of the first groove B1314. This prevents the first slider B141 from disengaging from the second track B132 during sliding, and the second slider B142 from disengaging from the first track B131 during sliding. This also prevents the first positioning component B110 from disengaging from the second positioning component B120 during rotation and displacement. Furthermore, the length of the first slider B1412 along the extension direction of the second track B132 is greater than the width W3 of the first channel B1313, and the length of the second slider B1422 along the extension direction of the first track B131 is greater than the width W2 of the second channel B1323. In this way, the first slider B141 is confined to slide within the second track B132, and the second slider B142 is confined to slide within the first track B131, preventing the first slider B141 from entering the first track B131 and the second slider B142 from entering the second track B132. Of course, in other embodiments, the first track B131 and the second track B132 can be groove structures provided on the upper surface of the second top cover B122. The first slider B141 can slide within one of the first track B131 and the second track B132 via the first slider B1412, and the second slider B142 can slide within the other of the first track B131 and the second track B132 via the second slider B1422. In one embodiment, both the first slider B141 and the second slider B142 are integrally formed structures, that is, the first slider B1412 and the first sliding rod B1411 are integrally formed, and the second slider B1422 and the second sliding rod B1412 are integrally formed, and the second slider B1422 and the second sliding rod B1412 are integrally formed. Of course, in other embodiments, the first slider B1412 and the first sliding rod B1411 are different components. The first slider B141 can be formed by connecting the first slider B1412 and the first sliding rod B1411 through welding, riveting, or other methods; similarly, the second slider B1422 and the second sliding rod B1421 are also different components, and the second slider B1422 can be formed by connecting the second slider B1422 and the second sliding rod B1412 through welding, riveting, or other methods.

[0310] It should be noted that the above-mentioned "through groove structure" refers to a groove that is connected to the second mounting cavity B121, while the "groove structure" refers to a groove that is not connected to the second mounting cavity B121.

[0311] See Figures 55 to 57The vehicle body B300 can be, for example, a seat, a carrier, or a sleeping box. As described above, when the vehicle body B1000 is installed inside a vehicle, the vehicle body B300 can rotate to any one of the following directions under the action of the first positioning component B110: a first direction F1, a second direction F2, a third direction F3, or a fourth direction F4. This gives the vehicle body B300 four modes: forward mode, left-facing mode, rear-facing mode, and right-facing mode. Specifically, when it is necessary to place a child in or remove a child from the vehicle body B300, the vehicle body B300 can be in the left-facing or right-facing mode for easy retrieval. When the vehicle needs to move, the vehicle body B300 can be in the forward-facing or rear-facing mode, thus improving the safety of children during travel. Specifically, to further consider the safety of children traveling, especially for younger children (e.g., under 15 months), shorter children, or lighter children, the vehicle body B300 should not be in forward mode, that is, the vehicle body B300 should not face the front of the car (i.e., the first direction F1). However, in actual use, users may mistakenly adjust the orientation of the first positioning component B110 relative to the second positioning component B120, thereby misusing the forward or rearward mode of the vehicle body B300, posing a safety hazard to children traveling in the vehicle.

[0312] To prevent users from misusing different usage modes of the vehicle body B300, in one embodiment of the fourth aspect of this utility model, the positioning component B100 may further include an anti-misuse mechanism B150. This anti-misuse mechanism B150 may be movably disposed on the first positioning component B110 or the second positioning component B120, and is used to selectively allow or restrict the movement of the sliding components (first slider B141 or second slider B142), thereby selectively restricting the angle of rotation of the first positioning component B110 relative to the second positioning component B120. For example, the anti-misuse mechanism B150 may restrict the movement of the first slider B141, thus restricting the first positioning component B110 from rotating relative to the second positioning component B120 to the second direction F2 or the fourth direction F4. Alternatively, the anti-misuse mechanism B150 may restrict the movement of the second slider B142, thus restricting the first positioning component B110 from rotating relative to the second positioning component B120 to the first direction F1 or the third direction F3.

[0313] See Figures 65 to 67In one embodiment, the anti-misuse mechanism B150 includes a blocking member B151. The blocking member B151 is movably disposed on the first positioning component B110 or the second positioning component B120 to extend into or retract from the first track B131 or the second track B132, thereby selectively allowing or restricting the movement of the first slider B141 or the second slider B142. Specifically, the blocking member B151 is movably disposed and has a first position and a second position. In this embodiment, the specific structure and working principle of the anti-misuse mechanism B150 are illustrated by taking the example of the anti-misuse mechanism B150 being movably disposed on the second positioning component B120 and used to restrict the movement of the second slider B142.

[0314] Specifically, in one embodiment, the blocking member B151 is movably disposed in the second mounting cavity B121 of the second positioning assembly B120. When the blocking member B151 is in the first position (see...), Figure 66 The blocking member B151 extends at least partially into the first track B131 to block the movement of the second sliding member B142 within the first track B131, thereby restricting the rotation of the first positioning assembly B110 relative to the second positioning assembly B120 towards the forward or rearward direction of the vehicle. Specifically, viewed from the intersection center B133, the first track B131 has a first track segment B1311 extending along a first direction F1 and a second track segment B1312 extending along a third direction F3. Therefore, when the blocking member B151 is in the first position, it can be considered to restrict the rotation of the first positioning assembly B110 relative to the second positioning assembly B120 towards the first direction F1 or the third direction F3. When the blocking member B151 is in the second position (see...), Figure 65 When the blocking component B151 exits the first track B131, the first positioning component B110 can rotate freely relative to the second positioning component B120.

[0315] Please combine Figure 62 , Figure 63 , Figure 65 and Figure 66In one embodiment, the blocking member B151 is movably disposed on the movement path of the second sliding member B142 within the second track segment B1312, that is, the blocking member B151 is movably disposed in the area of ​​the second mounting cavity B121 corresponding to the second track segment B1312. Specifically, when the second sliding member B142 moves from the intersection center B133 to the second track segment B1312, and the blocking member B151 is in the first position, the blocking member B151 extends at least partially into the second track segment B1312 to restrict the movement of the second sliding member B142 within the second track segment B1312, thereby restricting the first positioning component B110 from rotating relative to the second positioning component B120 toward the first direction F1. In other words, when the first positioning component B110 switches from the second direction F2 or the fourth direction F4 to the first direction F1 relative to the second positioning component B120, if the blocking member B151 is in the first position, the blocking member B151 will prevent the second sliding member B142 from moving away from the intersection center B133 within the second track section B1312, thereby restricting the first positioning component B110 from rotating to the first direction F1. Consequently, the vehicle body B300 cannot be used facing the first direction F1. This can remind the user and avoid misusing the forward mode of the vehicle body B300.

[0316] Please see Figure 66 In one embodiment, the anti-misuse mechanism B150 further includes a first reset member B153. The first reset member B153 abuts against the blocking member B151 to provide an elastic restoring force to the blocking member B151, thereby driving the blocking member B151 to remain constantly in a first position. In this embodiment, the blocking member B151 is disposed at the end of the second track segment B1312 away from the intersection center B133. Specifically, please refer to... Figure 62 , Figure 63 , Figure 65 and Figure 66 When the first positioning component B110 is oriented in the first direction F1 relative to the second positioning component B120, the first slider B141 is located at the intersection center B133, and the second slider B142 is located at the end of the second track segment B1312 away from the intersection center B133. At this time, the blocking member B151 is located directly below the second slider B142. More specifically, the blocking member B151 is located directly below the second slider B1422, and the blocking member B151 is pressed against by the second slider B1422 and held in the second position (see...). Figure 65At this time, the first positioning component B110 can freely switch from the first direction F1 to other directions (such as the second direction F2) relative to the second positioning component B120. More specifically, when the first positioning component B110 switches from facing the first direction F1 to other directions relative to the second positioning component B120, the second slider B1422 will move with the second sliding rod B1421 and become misaligned with the blocking member B151. Specifically, when the second slider B1422 is misaligned with the blocking member B151, the blocking member B151 is no longer pressed by the second slider B1422. At this time, the blocking member B151 switches to the first position under the reset force of the first reset member B153 to extend into the second track section B1322, thereby preventing the second slider B1422 from moving to the end of the second track section B1322 away from the intersection center B133, thus restricting the first positioning component B110 from rotating from other directions to facing the first direction F1. It can be seen that the aforementioned blocking member B151 can allow the first positioning component B110 to switch from the first direction F1 to other directions, while restricting the first positioning component B110 from switching from other directions to the first direction F1.

[0317] In some other embodiments, when the first positioning component B110 rotates relative to the second positioning component B120 to face the first direction F1, the first slider B141 is located at the intersection center B133, and the second slider B142 is located at the end of the second track segment B1312 away from the intersection center B133. The blocking component B151 can be offset from the second slider B1422. Specifically, the blocking component B151 is located in front of the second slider B1422 along the first direction F1. At this time, the blocking component B151 does not abut against the second slider B1422. The blocking component B151 is held in the first position by the reset force of the first reset component B153. In this way, the blocking component B151 will prevent the second slider B142 from moving in the second track segment B1312 towards the intersection center B133, thereby restricting the rotation of the first positioning component B110 relative to the second positioning component B120, which in turn prevents the first positioning component B110 from directly switching to the second direction F2 or the fourth direction F4.

[0318] Of course, in some other embodiments, the blocking member B151 has a guide ramp (not shown) on the side facing away from the intersection center B133. Thus, when the first positioning component B110 is facing the first direction F1, even if the blocking member B151 is in the first position, under the action of the guide ramp, the second slider B1422 can push the blocking member B151 as it slides towards the intersection center B133, causing the blocking member B151 to exit the second track segment B1312. This ultimately allows the first positioning component B110 to rotate relative to the second positioning component B120 from facing the first direction F1 to the second direction F2 or the fourth direction F4, etc. Because the guide ramp is located on the side of the blocking member B151 facing away from the intersection center B133, the first positioning component B110 can switch from facing the first direction F1 to other directions while also restricting the first positioning component B110 from switching from facing other directions (such as the second direction F2 or the fourth direction F4) back to facing the first direction F1, thus preventing the misuse of the forward mode of the vehicle body B300. Of course, in other embodiments, when the first positioning component B110 is oriented relative to the second positioning component B120 in the first direction F1, the second slider B1422 may also have a guide slope on the side near the intersection center B133. This also achieves the aforementioned effect.

[0319] See Figures 66 to 69 In one embodiment, the anti-misuse mechanism B150 further includes a release component B152. This release component B152 is disposed on the first positioning component B110 or the second positioning component B120 and is drivenly connected to the blocking member B151, for driving the blocking member B151 out of the first track B131 or the second track B132, thereby allowing the movement of the first sliding member B141 or the second sliding member B142. Specifically, in this embodiment, the release mechanism B152 is disposed on the second positioning component B120 and is drivenly connected to the blocking member B151, for driving the blocking member B151 to switch from a first position to a second position. Thus, the first positioning component B110 can freely switch between various directions relative to the second positioning component B120.

[0320] See also Figures 66 to 69 In one embodiment, the release assembly B152 may include an operating member B1521 and a traction member B1522. The operating member B1521 is movably disposed on the second positioning assembly B120 and has a locked position and an released position. The traction member B1522 is connected between the operating member B1521 and the blocking member B151. Specifically, as... Figure 68 As shown, the second top cover B122 has a through hole B1222. The operating member B1521 is movably disposed within the second mounting cavity B121. The operating part of the operating member B1521 extends out of the second mounting cavity B121 through the through hole B1222 and protrudes from the surface of the second top cover B122, thus facilitating user operation. Figure 67 , Figure 69 as well as Figure 70 As shown, the traction member B1522 is, for example, a traction rope, which is disposed within the second mounting cavity B121 and connected to the operating member B1521 and the blocking member B151. When the operating member B1521 moves and switches from the locked position to the unlocked position, the operating member B1521 drives the blocking member B151 out of the first track B131 via the traction member B1522, which is equivalent to driving the blocking member B151 to switch from the first position to the second position (from the first position to the second position). Figure 66 Towards Figure 65 Switch).

[0321] Optionally, in some embodiments, the operating component B1521 is provided with a prompt mark, which can be used to directly remind the user whether the first positioning component B110 should be facing the first direction F1. The prompt mark can remind the user through a prompt message, pattern, symbol, signal, or alarm. For example, the prompt message on the sign can be ">15 months" and "<15 months". When the operating component B1521 is in the unlocked state, the prompt message "">15 months" is displayed to remind the user that the first positioning component B110 can be set to face the first direction F1, allowing children older than 15 months to ride in the vehicle body B300 in forward mode; when the operating component B1521 is in the locked state, the prompt message "<15 months" is displayed to remind the user that the first positioning component B110 cannot be set to face the first direction F1, and the vehicle body B300 cannot use forward mode.

[0322] See Figures 65 to 67 as well as Figure 70 In one embodiment, the anti-misuse mechanism B150 further includes a fixing base B154. The fixing base B154 is disposed within the second mounting cavity B121, and has a cavity B1541, a first opening B1542 communicating with the cavity B1541, and an operating hole B1543. The first opening B1542 and the operating hole B1543 are opposite to each other and face the first track B131. A first reset member B153 is disposed within the cavity B1541 and abuts against the blocking member B151; that is, the blocking member B151 is movably disposed within the cavity B1541, and the first reset member B153 is disposed within the cavity B1541 and abuts against the blocking member B151 and the fixing base B154. A traction member B1522 passes through the operating hole B1543 and is connected to the blocking member B151. When the blocking member B151 is in the first position, the blocking member B151 at least partially passes through the first opening B1542 and extends into the first track B131. Specifically, as Figure 67 and Figure 70As shown, the side wall of the fixed base B154 is provided with a strip-shaped guide groove B1544, and the extending direction of the guide groove B1544 is the same as the moving direction of the blocking member B151. A connecting shaft B156 is inserted through the blocking member B151. The connecting shaft B156 extends into the guide groove B1544 and slides in cooperation with the guide groove B1544, so that the blocking member B151 can slide along the guide groove B1544 of the fixed base B154 into or out of the first track B131, thereby restricting or allowing the first positioning assembly B110 to face the first direction F1.

[0323] See Figure 65 and Figure 66 In one embodiment, "the blocking member B151 at least partially passes through the first opening B1542 and extends into the first track B131" specifically means that the blocking member B151 extends into the first channel B1313 of the second track segment B1312, so that at least part of the blocking member B151 is located on the movement path of the second slider B1422, thereby preventing the first positioning assembly B110 from rotating toward the first direction F1.

[0324] In order to stably hold the blocking member B151 in the second position, in one embodiment, such as Figures 67 to 69 As shown, the anti-misuse mechanism B150 also includes a status locking component B155. This status locking component B155 is disposed on the second positioning component B120 and is used to lock the operating member B1521 in a locked or unlocked position. By locking the operating member B1521 in the unlocked position, the traction member B1522 is kept in a taut state, ultimately holding the blocking member B151 in the second position.

[0325] See Figures 68 to 72In one embodiment, the state locking component B155 may include a locking member B1551. The locking member B1551 is movably disposed on the second positioning component B120, specifically within the second mounting cavity B121, and has a third position and a fourth position. Specifically, the operating member B1521 has a limiting portion B15211. When the locking member B1551 is in the third position, it abuts against the limiting portion B15211, thereby restricting the operating member B1521 from switching between the unlocked and locked positions. This means the locking member B1551 can lock the operating member B1521 in either the unlocked or locked position, thus allowing the blocking member B151 to remain in the second or first position. When the locking member B1551 is in the fourth position, it separates from the limiting portion B15211. Thus, the operating member B1521 can freely switch between the locked and unlocked positions. It should be noted that the moving direction of the operating member B1521 intersects with the moving direction of the locking member B1551. Specifically, in this embodiment, the wall surface in contact with the limiting part B15211 is an arc-shaped structure, and the wall surface in contact with the limiting part B15211 and the locking member B1551 is also an arc-shaped structure. This allows the operating member B1521 to switch between the locked position and the unlocked position, and improves the smoothness of the switching.

[0326] Specifically, in this embodiment, such as Figures 68 to 72As shown, the state locking assembly B155 may further include a second reset member B1552, which abuts between the second positioning assembly B120 and the locking member B1551 to provide an elastic restoring force to the locking member B1551, thereby driving the locking member B1551 to be constantly held in the third position. When it is necessary to switch the blocking member B151 from the first position to the second position, the user can operate (e.g., push or pull) the operating member B1521 to move it from the locked position to the unlocked position. During this process, the operating member B1521 can overcome the elastic force of the second reset member B1552 to push the locking member B1551, so that the locking member B1551 can switch from the third position to the fourth position. In addition, during the pushing process, since the wall surface in contact with the locking member B1551 and the limiting part B15211 is an arc-shaped structure, and the wall surface in contact with the limiting part B15211 and the locking member B1551 is also an arc-shaped structure, the limiting part B15211 can overcome the obstruction of the locking member B1551, so that the operating member B1521 can switch to the unlocking position. When the limiting part B15211 passes the locking member B1551, the locking member B1551 automatically switches from the fourth position to the third position under the elastic restoring force of the second reset member B1552. That is, the locking member B1551 switches from one side of the limiting part B15211 to the other side of the limiting part B15211, so that it can again abut against the operating member B1521 (i.e., the other side of the limiting part B15211), locking the operating member B1521 in the unlocked position. Similarly, when it is necessary to switch the blocking member B151 from the second position to the first position, the user can operate the operating member B1521 again to move it from the unlocked position to the locked position. During this process, the operating member B1521 can also overcome the elastic force of the second reset member B1552 to push against the locking member B1551, so that the locking member B1551 switches from the third position to the fourth position again. Similarly, since both the wall surfaces where the locking member B1551 contacts the limiting member B15211 and the wall surfaces where the limiting member B15211 contacts the locking member B1551 are arc-shaped, the limiting member B15211 can overcome the obstruction of the locking member B1551, allowing the operating member B1521 to switch to the locked position. After the limiting member B15211 passes the locking member B1551, the locking member B1551 automatically switches from the fourth position to the third position under the elastic restoring force of the second reset member B1552, so that it can again abut against the operating member B1521 and lock the operating member B1521 in the locked position.

[0327] The following diagram illustrates the working principle and process of the anti-misuse mechanism B150 in preventing the movement of the second sliding member B142.

[0328] See Figures 65 to 69When the operating member B1521 is in the unlocked position, the traction member B1522 is tightened, thereby pulling the blocking member B151 away from the second track segment B1312 of the first track B131. Under the action of the second reset member B1552, the locking member B1551 can be held in the third position, so that the locking member B1551 can abut against the limiting part B15211 of the operating member B1521, so that the operating member B1521 is held in the unlocked position. In this way, the vehicle body B300 can rotate with the first positioning component B110 relative to the second positioning component B120 to face the first direction F1 (combined with...). Figure 55 and Figure 63 ).

[0329] When it is necessary to prevent the user from accidentally switching the first positioning component B110 from any of the directions facing the second direction F2, the third direction F3, or the fourth direction F4 back to the first direction F1, such as Figures 67 to 69 As shown, the operating member B1521 can be operated (e.g., pushed) to switch the operating member B1521 from the unlocked position to the locked position. Figure 59 Towards Figure 58 (Switching). During the switching process from the unlocking position to the locking position, the operating member B1521 pushes the locking member B1551 to move from the third position to the fourth position. After the operating member B1521 is in the locked position, under the action of the second reset member B1552, the locking member B1551 resets to the third position and abuts against the limiting part B15211 of the operating member B1521, thus keeping the operating member B1521 in the locked position. As the operating member B1521 gradually switches from the unlocking position to the locking position, the traction member B1522 gradually loosens, such as... Figure 65 and Figure 66 As shown, under the action of the first reset member B153, the blocking member B151 can be driven to switch from the second position to the first position, thereby extending into the second track segment 1312 of the first track 131 to block the second sliding member B142 from moving away from the intersection center B133, thus restricting the first positioning component B110 from rotating relative to the second positioning component B120 to face the first direction F1, so that the vehicle body 300 cannot switch to the forward mode (see...). Figure 55 and Figure 56 ).

[0330] Similarly, when a user needs to use the forward-facing mode of the vehicle body B300, such as Figures 67 to 69 As shown, the operating member B1521 can be operated (e.g., pushed) to switch the operating member B1521 from the locked position to the unlocked position. Figure 58 Towards Figure 59(Switching). During the switching process from the locked position to the unlocked position, the operating member B1521 pushes the locking member B1551 to move from the third position to the fourth position. After the operating member B1521 is in the unlocked position, under the action of the second reset member B1552, the locking member B1551 is reset to the third position and abuts against the limiting part B15211 of the operating member B1521, thus keeping the operating member B1521 in the unlocked position. As the operating member B1521 gradually switches from the locked position to the unlocked position, the traction member B1522 is gradually tightened, thereby pulling the blocking member B151 out of the second track segment B1312 of the first track B131, that is, switching from the first position to the second position (see...). Figure 66 and Figure 65 Thus, the first positioning component B110 rotates relative to the second positioning component B120 to face the first direction F1, allowing the vehicle body B300 to switch to forward mode (see...). Figure 55 and Figure 56 ).

[0331] As described above, when the anti-misuse mechanism B150 is disposed on the movement path of the second slider B142 on the first track B131, it can block the movement of the second slider B142, thereby restricting the first positioning component B110 from rotating relative to the second positioning component B120 in the direction of extension toward the first track B131. Of course, in other embodiments, the anti-misuse mechanism B150 can also be disposed on the movement path of the first slider B141 on the second track B132, thus blocking the movement of the first slider B141 and restricting the first positioning component B110 from rotating relative to the second positioning component B120 in the direction of extension toward the second track B132. Specifically, the working principle of the anti-misuse mechanism B150 in blocking the movement of the first slider B141 can be referred to the working principle of the anti-misuse mechanism B150 in blocking the movement of the second slider B142 described above, and will not be repeated here.

[0332] In this embodiment, as described above, when the vehicle body B300 on the first positioning component B110 is oriented towards the first direction F1 relative to the second positioning component B120, the position of the second slider B142 on the first positioning component B110 is located behind the first slider B141 along the first direction F1. Of course, in some other embodiments not shown, when the vehicle body B300 on the first positioning component B110 is oriented towards the first direction F1 relative to the second positioning component B120, the position of the second slider B142 on the first positioning component B110 can also be located in front of the first slider B141. In this case, when the first slider B141 is located at the intersection center B133 (i.e., point M), the second slider B142 is located at the first track segment B1311 and at point N” (see reference). Figure 62 When the first positioning component B110 needs to switch relative to the second positioning component B120 from the first direction F1 to the second direction F2, the user can similarly pull the first positioning component B110 or the vehicle body B300, and while pulling, the first positioning component B110 will tend to rotate counterclockwise. This allows the first sliding member B141 to move from point M to point M” within the second track B132, and simultaneously allows the second sliding member B142 to move synchronously from point N” to point N' within the first track B131. During this process, the first positioning component B110 gradually begins to rotate relative to the second positioning component B120, and can also move laterally (specifically along the right side) relative to the second positioning component B120. When the first slider B141 moves to M”, the second slider B142 is located at point N’, i.e., at the intersection center B133. At this time, the first positioning component 110 faces the second direction F2 relative to the second positioning component B120, and is recessed relative to the left edge of the second positioning component B120, while protruding from the right edge. It can be seen that regardless of whether the second slider B142 is located in front of or behind the first slider B141 along the first direction F1, the first positioning component B110 can rotate relative to the second positioning component B120 to change the orientation of the first positioning component B110.

[0333] Specifically, when the carrier body B300 on the first positioning component B110 is oriented towards the first direction F1 relative to the second positioning component B120, and the second slider B142 is located in front of the first slider B141 along the first direction F1, the blocking member B151 is movably disposed on the movement path of the second slider B142 on the first track B131. More specifically, the blocking member B151 is movably disposed within the first track segment B1311. In this way, the rotation of the first positioning component B110 relative to the second positioning component B120 towards the extension direction of the first track B131 (e.g., towards the first direction F1). Specifically, the working principle of the blocking member B151 in blocking the movement of the second slider B142 on the first track segment B1311 can be referred to the working principle of the blocking member B151 in blocking the movement of the second slider B142 on the second track segment B1312 described above, and will not be repeated here.

[0334] As stated above, when the vehicle is in motion, the vehicle body B300 needs to be oriented towards either the first direction F1 or the third direction F3. Specifically, as follows... Figure 61 and Figure 63 As shown, when the first positioning component B110 faces the first direction F1 or the third direction F3, the user can lock the first positioning component B100 in the direction of the first direction F1 or the third direction F3 using the locking mechanism B210 on the positioning component B100. This prevents the vehicle body B300 from rotating arbitrarily with the first positioning component B110 relative to the second positioning component B120 during vehicle operation, thus ensuring the child's safety. More specifically, the locking mechanism B210 can only be used to lock the first positioning component B110 when it is directly facing the first direction F1 or the third direction F3 relative to the second positioning component B120. To determine whether the first positioning component B110 is directly facing the first direction F1 or the third direction F3, in one embodiment, the positioning component B100 further includes an engagement indication mechanism B160 (see...). Figure 73 and Figure 74The engagement indication mechanism B160 can be disposed on the first positioning component B110 or the second positioning component B120, and is used to indicate whether the first positioning component B110 rotates relative to the second positioning component B120 to an extension direction toward the first track B131; in...
