[0170] To make the above-mentioned objects, features, and advantages of the present disclosure more clearly understood, specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present disclosure. However, the present disclosure can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present disclosure. Therefore, the present disclosure is not limited to the specific embodiments disclosed below.

[0171] In a first aspect, the present invention provides a vehicle A1000, comprising a vehicle body A200 and a positioning assembly A100 provided in some embodiments of the present invention. The vehicle body A200 can be fixedly mounted on the positioning assembly A100; however, the vehicle body A200 can also be detachably mounted on the positioning assembly A100. The vehicle body A200 can be mounted to a car seat (not shown) via the positioning assembly A100. The following description of the vehicle A1000 will also include an explanation of the vehicle body A200 and the positioning assembly A100.

[0172] In one embodiment, the type of the carrier body A200 can be, for example, a child safety seat (see Figure 14), an infant safety carrier (see Figure 41) or a sleeping box, and the user can select the type of the carrier body A200 according to the adaptability of the child's age, height or weight. Specifically, a snap-fitting part A210 (see Figure 48) is provided at the bottom of the carrier body A200. As shown in Figures 1 and 2, the positioning assembly A100 may include a first positioning assembly A110 and a second positioning assembly A120. Among them, the first positioning assembly A110 is used to connect the carrier body A200, and the second positioning assembly A120 is used to connect the car seat. Specifically, a first connecting mechanism A150 is provided on the first positioning assembly A110, and the first connecting mechanism A150 is used to be detachably connected to the snap-fitting part A210 of the carrier body A200. Specifically, the first connecting mechanism A150 includes a snap-fitting hook A151, which is pivotally connected to the first positioning assembly A110 and has a locking position and a release position. When the engaging hook A151 is in the locked position, the engaging hook A151 is used to engage and lock with the engaging member A210; when the engaging hook A151 is in the unlocked position, the engaging member A210 can be disengaged from the engaging hook A151, so that the carrier body A200 can be disengaged from the first positioning assembly A110. More specifically, the specific structure of the first connecting mechanism A150 can be found in the detailed description below. The second positioning assembly A120 is provided with a seat connecting mechanism A161 (such as an ISOFIX connector) and a support leg A162. The seat connecting mechanism A161 is mainly used to fix the second positioning assembly 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 assembly A100.

[0173] In the positioning assembly A100 provided by the aforementioned carrier A1000, one of the first positioning assembly A110 and the second positioning assembly 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 arranged to intersect and 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. 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 assembly A110 rotates and slides relative to the second positioning assembly 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.

[0174] In order 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 rail segment A1311 away from the intersection center A133 is regarded as point N", the end of the second rail segment A1312 away from the intersection center A133 is regarded as point N, the end of the third rail segment A1321 away from the intersection center A133 is regarded as point M', and the end of the fourth rail segment A1322 away from the intersection center A133 is regarded as point M".

[0175] Referring to Figures 3 and 4 , in the positioning assembly A100 provided in the first embodiment, the second positioning assembly A120 is provided with a first track A131 and a second track A132 arranged in a cross-direction (see Figure 4 ). Specifically, the first track A131 extends along the first direction F1 or the third direction F3, and the second track A132 extends along the second direction F2 or the fourth direction F4. More specifically, the first track segment A1311 extends from the intersection center A133 in the first direction F1, and the second track segment A1312 extends from the intersection center A133 in the third direction F3. The third track segment A1321 extends from the intersection center A133 in the second direction F2, and the fourth track segment A1322 extends from the intersection center A133 in the fourth direction F4. The first direction F1 is parallel to and opposite to the third direction F3, the second direction F2 is parallel to and opposite to the fourth direction F4, and the first direction F1 intersects the second direction F2. More specifically, the first direction F1 is perpendicular to the second direction F2. The first positioning component A110 is provided with a first sliding member A141 and a second sliding member A142 (see FIG3 ). 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 arranged offset from the rotation axis (see FIG3 , FIG15 , FIG20 and FIG23 ). Specifically, in the present embodiment, when the first positioning component A110 is roughly in the shape of a disk, the above-mentioned rotation axis can be regarded as the center of the circle of the first positioning component A110. Of course, in other embodiments, the first positioning component A110 can be other symmetrical shapes (such as an ellipse, a rectangle, etc.), and the rotation axis can be the geometric center position of the first positioning component A110 or offset from the geometric center position; or, the first positioning component A110 can also be an asymmetric shape, and the rotation axis can be set according to actual needs.

[0176] It should be noted that, with the normal driving of the car as a reference, the first direction F1 refers to the front of the normal driving of the car when the positioning component A100 is installed on the car seat, which is equivalent to the direction toward the front of the car. The third direction F3 can be regarded as the rear of the normal driving of the car, that is, the direction toward the rear of the car. The second direction F2 can be regarded as the left direction of the normal driving of the car, that is, the second direction F2 is the direction toward the left door of the car. The fourth direction F4 can be regarded as the right direction of the normal driving of the car, that is, the direction toward the right 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. In order to clearly understand the various ends of the first positioning component A110, taking the installation of the carrier body A200 on the first positioning component A110 as an example, the front-to-back direction of the carrier body A200 is parallel to the front-to-back direction of the first positioning component A110, and the left-to-right direction of the carrier body A200 is parallel to the left-to-right direction of the first positioning component A110. Specifically, when an infant or child is riding in the carrier body A200, the front end of the first positioning component A110 is closer to the infant or child's feet than the rear end. Conversely, the rear end of the first positioning component A110 is closer to the infant or child's head than the front end. The left end of the first positioning component A110 is closer to the infant or child's left hand than the right end, and the right end of the first positioning component A110 is closer to the infant or child's right hand than the left end. When the first positioning component A110 is facing a certain direction, it means that the carrier body A200 is also facing the same direction; at the same time, the child riding in the carrier body A200 is also facing the same direction. To intuitively understand the front-to-back and left-to-right directions of the carrier body A200 and the first positioning component A110, the "front" and "back" directions are schematically indicated by arrows Q1 and Q3 in the respective figures, and the "left" and "right" directions are schematically indicated by arrows Q2 and Q4, respectively. Among them, the Q1 direction is parallel and opposite to the Q3 direction, the Q2 direction is parallel and opposite to the Q4 direction, and the Q1 direction is staggered with the Q2 direction. Specifically, the Q1 direction is perpendicular to the Q2 direction. These directional terms are only used to make the description of the embodiments of the present invention clearer and are not used to improperly limit the scope of protection of the present invention. The first positioning component A110 mentioned below is facing the first direction F1 relative to the second positioning component A120, which means that the front end of the first positioning component A110 is facing the first direction F1; the first positioning component A110 is facing the second direction F2 relative to the second positioning component A120, which means that the front end of the first positioning component A110 is facing the second direction F2; the first positioning component A110 is facing the third direction F3 relative to the second positioning component A120, which means that the front end of the first positioning component A110 is facing the third direction F3; the first positioning component A110 is facing the fourth direction F4 relative to the second positioning component A120, which means that the front end of the first positioning component A110 is facing the fourth direction F4.In order to clearly understand the setting position of the second sliding member A142 relative to the first sliding member A141 in the first embodiment, the setting position of the second sliding member A142 is explained below with reference to the first positioning component A110 being oriented in the first direction F1 relative to the second positioning component A120 and the first positioning component A110 being roughly disc-shaped.

[0177] In the first embodiment, with respect to the first positioning assembly A110, when the first sliding member A141 is positioned at the rotation axis, the second sliding member A142 can be positioned behind the first sliding member A141 (see FIG3 and FIG8 ). This means that when the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120, the first sliding member A141 is positioned at the intersection center A133, and the second sliding member A142 is positioned to one side of the first sliding member A141 along the third direction F3, that is, the second sliding member A142 is positioned at the second track segment A1312. In this way, the first positioning assembly A110 can rotate and slide relative to the second positioning assembly A120 by virtue of the first sliding member A141 sliding along the second track A132 and the second sliding member A142 sliding along the first track A131.

[0178] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding 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, when the first sliding component A141 is set at the rotation axis and the second sliding component A142 is set behind the first sliding component A141.

[0179] FIG1 shows a stereoscopic view of the positioning assembly A100 when the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120. FIG2 shows a stereoscopic view of the positioning assembly A100 when the first positioning assembly A110 is oriented in the third direction F3 relative to the second positioning assembly A120. FIG5 can be regarded as a top view of the positioning assembly A100 when the first positioning assembly A110 is oriented in the first direction F1 or the third direction F3 relative to the second positioning assembly A120 (the specific principle can be found later), wherein the first positioning assembly A110 is perspective-processed and replaced by a virtual circular structure. Similarly, the first positioning assembly A110 in FIG6, FIG7, FIG21 and FIG22 can be perspective-processed.

[0180] As shown in Figures 3 to 5, when the first sliding member A141 is arranged at the rotation axis and the second sliding member A142 is arranged behind the first sliding member A141 along the front-to-back direction of the first positioning component A110, when the first positioning component A110 is set in the first direction F1 relative to the second positioning component A120, the first sliding member A141 is located at the intersection center A133, that is, point M or point N', and the second sliding member A142 is located at the end of the second rail segment A1312 away from the intersection center A133, that is, point N.

[0181] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the first direction F1 to being set in the second direction F2, it is equivalent to changing the carrier body A200 from being set in the front to being set in the left direction. As shown in Figures 3 and 4, the user can directly pull the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first sliding member A141 can move from point M to point M' in the third rail segment A1321, and at the same time, the second sliding member A142 can synchronously move from point N to point N' in the second rail segment A1312 (switch from Figure 5 to Figure 6, and from Figure 8 to Figure 9). During this process, the first positioning assembly A110 gradually begins to rotate relative to the second positioning assembly A120, while simultaneously moving laterally from the intersection center A133 relative to the second positioning assembly A120 (specifically, moving in the left direction, the second direction F2) to protrude beyond the left edge of the second positioning assembly A120 (switch from Figure 1 to Figure 12). When the first sliding member A141 moves to point M', the second sliding member A142 is located at point N', i.e., the intersection center A133. At this point, the first positioning assembly A110 is oriented in the second direction F2 relative to the second positioning assembly A120, and the first positioning assembly A110 is pulled outward relative to the second positioning assembly A120 along the second direction F2. It should be noted that the switching process of the first positioning component A110 relative to the second positioning component A120 between 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 facing the first direction F1 to facing the second direction F2, and can also be switched from facing the second direction F2 to facing the first direction F1.

[0182] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the second direction F2 to being set in the third direction F3, it is equivalent to changing the carrier body A200 from being set in the left direction to being set in the rear direction. As shown in Figures 3 and 4, the user can pull the carrier body A200 to make the carrier body A200 drive the first positioning component A110 to move, 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 N' to point N" in the first rail segment A1311, and at the same time, the first sliding member A141 can move in the third rail segment A1312. 321 synchronously moves from point M' to point M (switch from Figure 6 to Figure 5, and switch from Figure 9 to Figure 10). 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 from the lateral direction (specifically the left direction, i.e., the second direction F2) to the intersection center A133 relative to the second positioning component A120 (switch from Figure 12 to Figure 2). When the second sliding member A142 moves to point N", the first sliding member A141 is located at point M, i.e., the intersection center A133, and at this time, the first positioning component A110 is facing 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 between the second direction F2 and the third direction F3 is reversible.

[0183] Furthermore, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the third direction F3 to being set in the fourth direction F4, it is equivalent to changing the carrier body A200 from being set towards the rear to being set towards the right, as shown in Figures 3 and 4. Pull the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first sliding member A141 can move from point M to point M” in the fourth rail segment A1322, so that the second sliding member A142 can synchronously move from point N” to point N' in the first rail segment A1311 (switch from Figure 5 to Figure 7, and from Figure 10 to Figure 11). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time can move from the intersection center A133 to the lateral direction relative to the second positioning component A120 (specifically, move along the right direction, i.e., the fourth direction F4) to protrude from the right edge of the second positioning component A120 (switch from Figure 2 to Figure 13). When the first sliding member A141 moves to the M" point, the second sliding member A142 is located at the N' point, i.e., 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 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 It is necessary to change the carrier body A200 from being set toward the right to being set toward the front, and directly pull the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise, so that the second sliding member A142 can move from point N' to point N in the second rail segment A1312, so that the first sliding member A141 synchronously moves from point M" to point M in the fourth rail segment A1322 (switch from Figure 7 to Figure 5, and from Figure 11 to Figure 8). 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 from the lateral direction (specifically the right direction, that is, the fourth direction F4) to the intersection center A133 relative to the second positioning component A120 (switch from Figure 13 to Figure 1). Likewise, the switching process of the first positioning component A110 relative to the second positioning component A120 between 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 between the fourth direction F4 and the first direction F1 is also reversible.

[0184] It should be noted that the above description uses the process of the first positioning assembly A110 rotating one revolution counterclockwise relative to the second positioning assembly A120 as an example to illustrate the principle of simultaneous rotation and sliding. Of course, the process of the first positioning assembly A110 rotating one revolution clockwise relative to the second positioning assembly A120 can also be used as an example to illustrate the principle of simultaneous rotation and sliding, and this description will not be repeated 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, that is, 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, that is, 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 sliding member A141 and the second sliding member A142 can be smaller 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, after the first positioning component A110 is rotated relative to the second positioning component A120 to face various directions, it can continue to slide in various directions. For example, when the first positioning component A110 rotates from the first direction F1 to the second direction F2 relative to the second positioning component A120, the second sliding member A142 is located at the intersection center A133, i.e., point M, and the first sliding member A141 is located between the two ends of the third rail 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 to move the first sliding member A141 and the second sliding member A142 on the third rail segment A1321 until the first sliding member A141 is located at the end of the third rail segment A1321 away from the intersection center A133, i.e., point M'. Alternatively, when the first positioning component A110 rotates from the first direction F1 to the second direction F2 relative to the second positioning component A120, the second sliding member A142 is located at the intersection center A133, i.e., point M, and the first sliding member A141 is located between the two ends of the third rail 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 sliding member A141 and the second sliding member A142 from the third rail segment A1321 to the fourth rail segment A1322.

[0186] It should be noted that the first positioning component A110 can be a disc-shaped structure, and the rotation axis is the center of the circle, so that the shape of the positive projection of the first positioning component A110 on the second positioning component A120 is symmetrical about the rotation axis of the first positioning component A110. In addition, when the lengths of each track segment are the same, the overlapping area and range between the two when the first positioning component A110 is rotated relative to the second positioning component A120 and faces the first direction F1 are the same as the overlapping area and range between the two when the first positioning component A110 is facing away from the first direction F1 relative to the second positioning component A120. In other words, when the first positioning component A110 is facing the first direction F1 relative to the second positioning component A120, the position of the first positioning component A110's positive projection on the second positioning component A120 is the same as the position of the first positioning component A110's positive projection on the second positioning component A120 when the first positioning component A110 is facing the third direction F3 relative to the second positioning component A120. Therefore, the carrier body A200 shown in Figure 5 can be regarded as the first positioning component A110 rotated relative to the second positioning component A120 to face the first direction F1, and can also be regarded as rotated to face the third direction F3.

[0187] According to the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 in the above-described situation, 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 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 direction, and can also be pulled outward relative to the second positioning component A120 to get closer to the vehicle door (the state can be seen in Figures 12 and 13). In this way, the carrier body A200 connected to the first positioning component A110 can get closer to the vehicle door when it rotates with the first positioning component A110 to the second direction F2 or the fourth direction F4 (the state can be seen in Figure 14). In other words, when the first positioning assembly A110 is oriented in the second direction F2 or the fourth direction F4 relative to the second positioning assembly A120, the first positioning assembly A110 can be simultaneously pulled outward relative to the second positioning assembly A120 to be closer to the vehicle door (e.g., the left or right door), thereby facilitating the user's ability to remove a child from or place the child into the vehicle body A200. This allows for simultaneous rotation (steering) and sliding (e.g., lateral pulling). Furthermore, since there is no need to perform steering followed by lateral pulling as is conventionally done, operational convenience is enhanced.

[0188] In the positioning assembly A100 provided in the first embodiment, as shown in FIG4 , the second positioning assembly A120 may include a second top cover A121 and a second bottom cover A122, which are connected to each other from top to bottom to form a second mounting cavity A123 (see FIG8 ). Referring to FIG3 , FIG4 , and FIG8 , specifically, the first sliding member A141 may include a first sliding rod A1411 and a first slider A1412, and the second sliding member A142 may further include a second sliding rod A1421 and a second slider A1422. As shown in Figures 8 to 10, the first track A131 may include a first channel A1313 and a first chute A1314, and the second track A132 may include a second channel A1323 and a second chute A1324, wherein the first channel A1313 and the second channel A1323 are both arranged on the lower surface of the second top cover A121, that is, facing the side of the second installation cavity A123, and the two intersect and communicate with each other, and the first channel A1313 and the second channel A1323 are both connected to the second installation cavity A123. The first chute A1314 is arranged on the inner side of the first channel A1313, and the second chute A1324 is arranged on the inner side of the second channel A1323, and the first chute A1314 and the second chute A1324 are both through-groove structures. The first sliding member A141 is connected to the rotation axis of the first positioning assembly A110 via a first sliding rod A1411. The second sliding member A142 is connected to the first positioning assembly A110 and offset from the rotation axis via a second sliding rod A1421. The first sliding rod A1411 extends into the second sliding groove A1324 and connects to the first slider A1412. The second sliding rod A142 extends into the first sliding groove A1314 and connects to the second slider A1422. The first sliding member A141 slides along the second track A132 via the first slider A1412, while the second sliding member 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 sliding member A141 can slide along the second track A132 via the first slider A1412, and the second sliding member A142 can slide along the first track A131 via the second slider A1422. It should be noted that the first sliding member A141 and the second sliding member 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 two are integrally formed.Of course, in other embodiments, the first slider A1412 and the first sliding rod A1411 can be different components, and the first sliding member A141 can be formed by connecting the first slider A1412 and the first sliding rod A1411 through welding, riveting, etc.; the second slider A1422 and the second sliding rod A1421 can also be different components, and the second sliding member A142 can be formed by connecting the second slider A1422 and the second sliding rod A1421 through welding, riveting, etc.

[0189] It should be noted that the above-mentioned “through groove structure” refers to the groove body connected to the second installation cavity A123, and the “groove structure” refers to the groove body not connected to the second installation cavity A123.

[0190] Referring to Figures 4 and 15 , a second embodiment of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of the positioning assembly A100 of the first embodiment, differing primarily in the position of the second sliding member A142. Unless otherwise specified, the following primarily describes the differences between this embodiment and the first embodiment.

[0191] Specifically, in the second embodiment, with respect to the first positioning assembly A110, when the first sliding member A141 is arranged at the center of the rotation axis, the second sliding member A142 can also be arranged in front of the first sliding member A141 along the front-to-back direction of the first positioning assembly A110 (see Figures 10 and 15). When the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120, the first sliding member A141 is located at the intersection center A133, and the second sliding member A142 is arranged in front of the first sliding member A141, that is, located on one side of the first sliding member A141 along the first direction F1. At this time, the second sliding member A142 is located on the first track section A1311. In this way, the first positioning assembly A110 can also rotate and slide relative to the second positioning assembly A120 with the help of the first sliding member A141 sliding along the second track A132 and the second sliding member A142 sliding along the first track A131.

[0192] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding 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, when the first sliding component A141 is set at the rotation axis and the second sliding component A142 is set in front of the first sliding component A141.

[0193] It should be noted that when the illustrations involved when the second sliding member A142 is arranged behind the first sliding member A141 are the same as the illustrations involved when the second sliding member A142 is arranged in front of the first sliding member A141, reference can be made to the explanation of the relevant illustrations in the first embodiment. In addition, the relationship between the distance between the first sliding member A141 and the second sliding member A142 and the length of each rail segment can be referred to as described in the first embodiment. Specifically, when the first sliding member A141 is arranged at the rotation axis and the second sliding member A142 is arranged in front of the first sliding member A141, referring to Figure 5, when the first positioning component A110 is arranged relative to the second positioning component A120 in the first direction F1, the first sliding member A141 is located at the intersection center A133, that is, point M or point N', and the second sliding member A142 is located at the end of the first rail segment A1311 away from the intersection center A133, that is, point N".

[0194] When the user needs to switch the first positioning assembly A110 relative to the second positioning assembly A120 from being oriented in the first direction F1 to being oriented in the second direction F2, this is equivalent to changing the carrier body A200 from being oriented forward to being oriented to the left. As shown in Figures 4 and 15, the user can directly pull the carrier body A200, causing it to move the first positioning assembly A110, causing it to rotate counterclockwise. In this way, the first sliding member A141 can be moved from point M to point M” in the fourth rail segment A1322, and at the same time, the second sliding member A142 can be synchronously moved from point N” to point N’ in the first rail segment A1311 (switching from Figure 5 to Figure 7, and from Figure 10 to Figure 11). It should be noted that the positioning assembly A100 shown in Figures 7, 10 and 11 referred to in this embodiment is slightly different from the positioning assembly A100 shown in the first embodiment when referring to the same Figures 7, 10 and 11. The difference is that: in this embodiment, when referring to Figures 7 and 11, the first positioning assembly A110 is facing the second direction F2; while in the first embodiment, when referring to Figures 7 and 11, the first positioning assembly A110 is facing the fourth direction F4. In addition, in this embodiment, when referring to Figure 10, the first positioning assembly A110 is facing the first direction F1; while in the first embodiment, when referring to Figure 7, the first positioning assembly A110 is facing 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 can move rightward from the intersection center A133 relative to the second positioning component A120, so as to retract relative to the left edge of the second positioning component A120 and protrude from the right edge (switching from Figure 1 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 sliding member A141 moves to the M" point, the second sliding member A142 is located at the N' point, that is, the intersection center A133. At this time, the first positioning component A110 is oriented in the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is retracted 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 being set toward the second direction F2 to being set toward the third direction F3, it is equivalent to changing the carrier body A200 from being set toward the left to being set toward the rear. As shown in Figures 4 and 15, the user can pull the carrier body A200 to cause the carrier body A200 to drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the second sliding member A142 can be moved from point N' to point N in the second rail segment A1312, and at the same time, the first sliding member A141 can be synchronously moved from point M" to point M in the fourth rail segment A1322 (switch from Figure 7 to Figure 5, and from Figure 11 to Figure 8). Similarly, the positioning component A100 shown in Figure 8 referenced in this embodiment is slightly different from the positioning component A100 shown in Figure 8 referenced in the first embodiment. The difference is that: in this embodiment, When referring to FIG8 in the embodiment, the first positioning assembly A110 is oriented in the third direction F3; while when referring to FIG8 in the first embodiment, the first positioning assembly A110 is oriented in the first direction F1. During this process, the first positioning assembly A110 gradually begins to rotate relative to the second positioning assembly A120, while the first positioning assembly A110 moves relative to the second positioning assembly A120 from the right edge toward the intersection center A133 (switching from FIG16 to FIG2). When the second slider A142 moves to N, the first slider A141 is located at point M, i.e., the intersection center A133. At this point, the first positioning assembly A110 is oriented in the third direction F3 relative to the second positioning assembly A120.

[0196] Furthermore, when the user needs to switch the first positioning assembly A110 relative to the second positioning assembly A120 from being oriented in the third direction F3 to being oriented in the fourth direction F4, it is equivalent to changing the carrier body A200 from being oriented toward the rear to being oriented toward the right. As shown in Figures 4 and 15, the carrier body A200 is pulled to cause the carrier body A200 to move the first positioning assembly A110, so that the first positioning assembly A110 has a tendency to rotate counterclockwise. In this way, the first sliding member A141 can move from point M to point M' within the third rail segment A1321, causing the second sliding member A142 to synchronously move from point N to point N' within the second rail segment A1312 (switch from Figure 5 to Figure 6, and from Figure 8 to Figure 9). Similarly, the positioning assembly A100 shown in Figures 6 and 9 in this embodiment is slightly different from the positioning assembly A100 shown in the first embodiment with reference to the same Figures 6 and 9. The difference is that in this embodiment, when referring to Figures 6 and 9, the first positioning assembly A110 is oriented in the fourth direction F4; whereas, when referring to Figures 6 and 9 in the first embodiment, the first positioning assembly A110 is oriented in the second direction F2. During this process, the first positioning assembly A110 gradually begins to rotate relative to the second positioning assembly A120, and can simultaneously move leftward from the intersection center A133 relative to the second positioning assembly A120, thereby retracting relative to the right edge of the second positioning assembly A120 and protruding beyond the left edge (from Figure 2 to Figure 18), that is, turning toward the fourth direction F4 and moving toward the second direction F2. When the first sliding member A141 moves to point M', the second sliding member A142 is located at point N', that 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 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 being set in the fourth direction F4 to being set in the first direction F1, it is equivalent to changing the carrier body A200 from being set in the right direction to being set in the front direction. The carrier body A200 is directly pulled to cause the carrier body A200 to drive the first positioning component A110 to move, 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 N' to point N" in the first rail segment A1311, so that the first sliding member A141 synchronously moves from point M' to point M in the second rail segment A1312 (switch from Figure 6 to Figure 5, and from Figure 9 to Figure 10). 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 from the left edge to the intersection center A133 relative to the second positioning component A120 (switch from Figure 18 to Figure 1).

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

[0198] According to the principle and process of the rotation and sliding of the first positioning assembly A110 relative to the second positioning assembly A120 in the aforementioned situation, it can be seen that when the first positioning assembly A110 rotates relative to the second positioning assembly A120 from the first direction F1 or the third direction F3 to the second direction F2 or the fourth direction F4, the first positioning assembly A110 can rotate relative to the second positioning assembly A120 to change its direction while also retracting inward relative to the second positioning assembly A120 to move away from the side door (see Figures 16 and 18). In this way, the vehicle body A200 connected to the first positioning assembly A110 can move away from the side door when facing the second direction F2 or the fourth direction F4 (see Figures 17 and 19). In other words, when the first positioning assembly A110 is oriented in the second direction F2 or the fourth direction F4 relative to the second positioning assembly A120, the first positioning assembly A110 can be retracted inward relative to the second positioning assembly A120 to move away from the side door, thereby preventing the carrier body A200 from hitting or interfering with the door when it rotates sideways. Furthermore, the distance between the front end of the carrier body A200 and the door is increased, providing more space for children to place their feet when riding in the sideways-mounted carrier body A200. Furthermore, since there is no need to turn the vehicle first and then retract sideways as in the traditional method, the convenience of operation is improved.

[0199] It should be noted that, in the above embodiment, the intersection center A133 can be the geometric center of the second positioning component A120, and the second positioning component A120 is symmetrically arranged relative to the axis of the first track A131. In this way, when the first positioning component A110 is facing the second direction F2 or the fourth direction F4, the first positioning component A110 can protrude or retract toward one side (for example, the left or right side) of the second positioning component A120 relative to the second positioning component A120.

[0200] Referring to Figures 4 and 20 , a third embodiment of the present invention provides a positioning assembly A100. This positioning assembly A100 can also be considered a variation of the positioning assembly A100 of the first embodiment, differing primarily in the position of the second sliding member A142. Similarly, unless otherwise noted, the following primarily describes the differences between this embodiment and the first embodiment.

[0201] Specifically, in the third embodiment, with respect to the first positioning assembly A110, when the first sliding member A141 is disposed at the rotation axis, the second sliding member A142 can also be disposed to the left of the first sliding member A141 along the front-to-rear direction of the first positioning assembly A110 (see FIG9 and FIG20 ). This means that when the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120 and the first sliding member A141 is located at the intersection center A133, the second sliding member A142 is disposed to one side of the first sliding member A141 along the second direction F2, that is, the second sliding member A142 is located at the third rail segment A1321. In this way, the first positioning assembly A110 can rotate and slide relative to the second positioning assembly A120 by virtue of the first sliding member A141 sliding along the first rail A131 and the second sliding member A142 sliding along the second rail A132.

[0202] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding relative to the second positioning component A120 under the action of the first sliding component A141 sliding along the first track A131 and the second sliding component A142 sliding along the second track A132, when the first sliding component A141 is arranged at the rotation axis and the second sliding component A142 is arranged to the left of the first sliding component A141 (that is, the second sliding component A142 is arranged on the side of the first sliding component A141 along the direction Q2).

[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 rail segment can be referred to as described in the first embodiment. Specifically, when the first slider A141 is positioned at the rotation axis and the second slider A142 is positioned to the left of the first slider A141, with reference to FIG5 , when the first positioning assembly A110 is positioned relative to the second positioning assembly A120 in the first direction F1, the first slider A141 is positioned at the intersection center A133, i.e., point M or point N', and the second slider A142 is positioned at the end of the third rail segment A1321 away from the intersection center A133, i.e., point M'.

[0204] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the first direction F1 to being set in the second direction F2. As shown in Figures 4 and 20, the user can directly pull the carrier body A200 to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first sliding member A141 can be moved from point M (i.e., point N') to point N" in the first rail section A1311, and at the same time, the second sliding member A142 can be synchronously moved from point M' to point M (i.e., point N') in the third rail section A1321 (switching from Figure 5 to Figure 21). 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 along the front and rear directions of the car from the intersection center A133 relative to the second positioning component A120 (specifically forward). The first positioning assembly A110 moves in the first direction F1) so that the first positioning assembly A110 can protrude from the edge of the front end of the second positioning assembly A120 along the first direction F1 (see Figure 21). When the first sliding member A141 moves to point N", the second sliding member A142 is located at point M (i.e., point N'), i.e., the intersection center A133. At this time, the first positioning assembly A110 is oriented in the second direction F2 relative to the second positioning assembly A120, and the first positioning assembly A110 is pulled outward relative to the second positioning assembly A120 along the first direction F1.

[0205] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the second direction F2 to being set in the third direction F3, as shown in Figures 4 and 20, the user can pull the carrier body A200 to cause the carrier body A200 to drive the first positioning component A110 to move, 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" in the fourth rail segment A1322, and at the same time, the first sliding member A141 can synchronously move from point N" to point M (i.e., point N') in the first rail segment A1311 (switching from Figure 21 to Figure 5). 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 from the front edge to the intersection center A133 relative to the second positioning component A120. When the second sliding member A142 moves to point M", the first sliding member A141 is located at point M (ie point N'), ie the intersection center A133. At this time, the first positioning component A110 is oriented in the third direction F3 relative to the second positioning component A120.

[0206] Furthermore, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the third direction F3 to being set in the fourth direction F4, as shown in Figures 4 and 20, the carrier body A200 is pulled to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise, so that the first sliding member A141 can move from point M (i.e., point N') to point N in the second rail segment A1312, so that the second sliding member A142 can be synchronously moved in the fourth direction F4. The track segment A1322 moves from point M" to point M (i.e., point N') (switch from Figure 5 to Figure 22). 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 along the front and rear directions of the vehicle from the intersection center A133 (specifically, backward, the third direction F3) to protrude from the rear end edge of the second positioning component A120 (see Figure 22). When the first sliding member A141 moves to point N, the second sliding member A142 is located at point M (i.e., point N'). At the intersection center A133, the first positioning component A110 is oriented toward 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 being oriented toward the fourth direction F4 to being oriented toward the first direction F1, the user directly pulls the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 is pulled outward along the third direction F3. Component A110 tends to rotate counterclockwise, causing the second slider A142 to move from point M (i.e., point N') to point M' within the third track segment A1321, and thus causing the first slider A141 to synchronously move from point N to point M (i.e., point N') within the second track segment A1312 (switch from Figure 22 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 its rear edge toward the intersection center A133 relative to the second positioning component A120.

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

[0208] According to the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 in the situation 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 fourth direction F4, the first positioning component A110 can rotate relative to the second positioning component A120 to change its orientation, and can also move backward relative to the second positioning component A120 along the front-to-back direction of the automobile. 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 can also move forward relative to the second positioning component A120 along the driving direction of the automobile (compare Figure 5 and Figure 21). Taking a seven-seater car as an example, usually, the rear door of the car is installed on the second row of seats. In this way, for example, when the carrier body A200 is installed on the third row of seats through the positioning component A100, the carrier body A200 is rotated to the left side, that is, the second direction F2, along with the first positioning component A110. The distance between the carrier body A200 and the rear left door can be reduced. In this way, it is convenient for users to put children into the carrier body A200 or take children out of the carrier body A200 at the rear left door.

[0209] Referring to Figures 4 and 23 , a fourth embodiment of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of the positioning assembly A100 of the third embodiment, differing primarily in the position of the second sliding member A142. Similarly, unless otherwise noted, the following primarily describes the differences between this embodiment and the third embodiment.

[0210] Specifically, in the fourth embodiment, with respect to the first positioning assembly A110, when the first sliding member A141 is disposed at the rotation axis, the second sliding member A142 can also be disposed to the right of the first sliding member A141 along the front-to-back direction of the first positioning assembly A110 (see FIG. 11 and FIG. 23 ). This means that when the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120 and the first sliding member A141 is located at the intersection center A133, the second sliding member A142 is located to one side of the first sliding member A141 along the fourth direction F4, that is, the second sliding member A142 is located at the fourth track segment A1322. In this way, the first positioning assembly A110 can also rotate and slide relative to the second positioning assembly A120 by virtue of the first sliding member A141 sliding along the first track A131 and the second sliding member A142 sliding along the second track A132.

[0211] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding relative to the second positioning component A120 under the action of the first sliding component A141 sliding along the first track A131 and the second sliding component A142 sliding along the second track A132, when the first sliding component A141 is arranged at the rotation axis and the second sliding component A142 is arranged to the right of the first sliding component A141 (that is, the second sliding component A142 is located on the side of the first sliding component A141 along the direction Q4).

[0212] Likewise, it should be noted that the relationship between the distance between the first sliding member A141 and the second sliding member A142 and the length of each rail segment can be referred to as described in the first embodiment. Specifically, when the first sliding member A141 is arranged at the rotation axis and the second sliding member A142 is arranged to the right of the first sliding member A141, when the first positioning component A110 is arranged in the first direction F1 relative to the second positioning component A120, the first sliding member A141 is located at the intersection center A133, that is, point M or point N', and the second sliding member A142 is located at the end of the fourth rail segment A1322 away from the intersection center A133, that is, point M".

[0213] When the user needs to switch the first positioning assembly A110 relative to the second positioning assembly A120 from being oriented in the first direction F1 to being oriented in the second direction F2, as shown in Figures 4 and 23, the user can pull the carrier body A200, causing the carrier body A200 to move the first positioning assembly A110, so that the first positioning assembly A110 tends to rotate counterclockwise. In this way, the first sliding member A141 can be moved from point M (i.e., point N') to point N in the second rail segment A1312, and at the same time, the second sliding member A142 can be synchronously moved from point M" to point M (i.e., point N') in the fourth rail segment A1322 (switched from Figure 5 to Figure 22). It should be noted that the positioning assembly A100 shown in Figure 22 referenced in this embodiment is slightly different from the positioning assembly A100 shown in Figure 22 referenced in the third embodiment. The difference is that: in this embodiment, when referring to Figure 22, the first positioning assembly A110 is oriented in the second direction F2; while in the third embodiment, when referring to Figure 22, the first positioning assembly A110 is oriented in the fourth direction F4. In this process First positioning assembly A110 gradually begins to rotate relative to second positioning assembly A120, while simultaneously moving forward and backward relative to second positioning assembly A120 (specifically, backward, in the third direction F3) from intersection center A133 along the front-to-rear direction of the vehicle (see FIG22 ). When first slider A141 moves to point N, second slider A142 is located at point M (i.e., point N'), i.e., intersection center A133. At this point, first positioning assembly A110 is oriented in the second direction F2 relative to second positioning assembly A120, and first positioning assembly A110 is pulled outward relative to second positioning assembly A120 along the third direction F3.

[0214] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the second direction F2 to being set in the third direction F3, as shown in Figures 4 and 23, the user can pull the carrier body A200 to cause the carrier body A200 to drive the first positioning component A110 to move, 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' in the third rail segment A1321, and at the same time, the first sliding member A141 can synchronously move from point N to point M (i.e., point N') in the second rail segment A1312 (switch from Figure 22 to Figure 5). 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 from the rear end edge to the intersection center A133 relative to the second positioning component A120. When the second sliding member A142 moves to point M', the first sliding member A141 is located at point M (ie point N'), ie the intersection center A133. At this time, the first positioning component A110 is oriented in the third direction F3 relative to the second positioning component A120.

[0215] Furthermore, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the third direction F3 to being set in the fourth direction F4, as shown in Figures 4 and 23, the carrier body A200 is pulled to cause the carrier body A200 to drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise, so that the first sliding member A141 can be moved from point M (i.e., point N') to point N" in the first rail segment A1311, so that the second sliding member A142 can be synchronously moved from point M' to point M (i.e., point N') in the fourth rail segment A1322 (switching from Figure 5 to Figure 21). Similarly, the positioning component A100 shown in Figure 21 referenced in this embodiment is slightly different from the positioning component A100 shown in Figure 21 referenced in the third embodiment. The difference is that: in this embodiment, when referring to Figure 21, the first positioning component A1 10 is oriented in the fourth direction F4; and when referring to Figure 21 in the third embodiment, the first positioning component A110 is oriented in 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 can move forward and backward relative to the second positioning component A120 from the intersection center A133 along the front and rear directions of the car (specifically, move forward, the first direction F1), so that the first positioning component A110 can protrude from the partial edge of the front end of the second positioning component A120 along the first direction F1 (see Figure 21). When the first sliding member A141 moves to the N” point, the second sliding member A142 is located at the M point (i.e., the N' point), i.e., 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 relative to the second positioning component A120 along the first direction F1. Similarly, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the fourth direction F4 to being set in the first direction F1, the user directly pulls the carrier body A200 to cause the carrier body A200 to drive the first positioning component A110 to move, 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" in the fourth rail segment A1322, so that the first sliding member A141 synchronously moves from point N" to point M (i.e. point N') in the first rail segment A1311 (switch from Figure 21 to Figure 5). 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 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 sliding member A141 is arranged at the rotation axis and the second sliding member A142 is arranged to the right of the first sliding member A141, the switching process of the first positioning component A110 relative to the second positioning component A120 toward the first direction F1 and the second direction F2 is reversible, and the switching process toward the second direction F2 and the third direction F3 is reversible. At the same time, the switching process toward the third direction F3 and the fourth direction F4 is reversible, and the switching process toward the fourth direction F4 and the first direction F1 is also reversible.

[0217] According to the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 in the situation 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 second direction F2, the first positioning component A110 can rotate relative to the second positioning component A120 to change its direction, and can also move backward relative to the second positioning component A120 along the front-to-back direction of the automobile. 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 direction, and can also move forward relative to the second positioning component A120 along the driving direction of the automobile (compare Figure 5 and Figure 21). Similarly, taking a seven-seater car as an example, when the carrier body A200 is installed on the third row of seats through the positioning assembly A100, when the carrier body A200 is rotated to the right side, that is, the fourth direction F4, along with the first positioning assembly A110, the distance between the carrier body A200 and the rear right door can be reduced. In this way, it is convenient for users to place children into the carrier body A200 or take children out of the carrier body A200 at the rear right door.

[0218] As can be seen from the above description, in the first to fourth embodiments, when the first sliding member A141 is positioned at the rotation axis, the second sliding member A142 can be positioned in front of, behind, to the left of, or to the right of the first sliding member A141 along the front-to-back direction of the first positioning assembly A110. In each embodiment, the first positioning assembly A110 can slide while rotating relative to the second positioning assembly A120. This improves user convenience.

[0219] Referring to Figures 24 and 25, the fifth embodiment of the present invention provides a positioning assembly A100. The positioning assembly A100 in this embodiment can be regarded as a variation of the positioning assembly A100 in the first embodiment. The positioning assembly A100 in this embodiment also includes a first positioning assembly A110 and a second positioning assembly A120. The main difference from the positioning assembly A100 in the first embodiment is that in this embodiment, the first positioning assembly A110 is provided with a first track A131 and a second track A132, and the second positioning assembly A120 is provided with a first slide A141 and a second slide A142. The first positioning assembly A110 also rotates and slides relative to the second positioning assembly A120 by means of the first slide A141 sliding along one of the first track A131 or the second track A132 and the second slide A142 sliding along the other of the first track A131 or the second track A132. Therefore, in the absence of conflict, the structure and connection relationship of the first positioning component A110 and the second positioning component A120 in this embodiment can refer to the description in the first embodiment above. The following mainly describes the differences between this embodiment and the above-mentioned first embodiment. It should be noted that in the positioning component A100 in this embodiment, the first track A131 and the second track A132 will change their extension directions relative to each other during the process of rotating and sliding with the first positioning component A110 (see below). In addition, it should be noted that in this embodiment, the first positioning component A110 can also face the first direction F1, the second direction F2, the third direction F3 and the fourth direction F4 relative to the second positioning component A120, wherein the first direction F1, the second direction F2, the third direction F3 and the fourth direction F4 are respectively the same as the first direction F1, the second direction F2, the third direction F3 and the fourth direction F4 referred to in the above-mentioned first embodiment, that is, they can be regarded as the front of the car, the rear of the car, the left direction of the car and the right direction of the car, respectively.

[0220] Specifically, in the positioning assembly A100 provided in the fifth embodiment, as shown in FIG24 , the first positioning assembly A110 is provided with a first track A131 and a second track A132. The first track segment A1311 extends forward from the intersection center A133 along the front-to-back direction of the first positioning assembly A110, i.e., along the Q1 direction; the second track segment A1312 extends backward from the intersection center A133 along the front-to-back direction of the first positioning assembly A110, i.e., along the Q3 direction; the third track segment A1321 extends leftward from the intersection center A133 along the left-to-right direction of the first positioning assembly A110, i.e., along the Q2 direction; and the fourth track segment A1322 extends rightward from the intersection center A133 along the left-to-right direction of the first positioning assembly A110, i.e., along the Q4 direction. As shown in FIG25 , the second positioning assembly A120 is provided with a first sliding member A141 and a second sliding member A142. The second positioning assembly A120 has a positioning axis. The first sliding member A141 is coaxially disposed with the positioning axis. The second sliding member A142 is offset from the positioning axis. For example, the second sliding member A142 is located to one side of the first sliding member A141 along the third direction F3. Specifically, the positioning axis can be the geometric center of the second positioning assembly A120.

[0221] In order to more clearly understand the setting position of the second sliding member A142 relative to the first sliding member A141 in the fifth embodiment, similarly, as in the first embodiment, the setting position of the second sliding member A142 is explained 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, with respect to the second positioning assembly A120, when the first sliding member A141 is positioned at the positioning axis, the second sliding member A142 can be positioned behind the first sliding member A141 (see FIG. 25 ), that is, the second sliding member A142 is positioned on one side of the first sliding member A141 along the third direction F3. When the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120, as shown in FIG. 26 , the first track segment A1311 can be considered to extend from the intersection center A133 toward the first direction F1, the second track segment A1312 can be considered to extend from the intersection center A133 toward the third direction F3, the third track segment A1321 can be considered to extend from the intersection center A133 toward the second direction F2, and the fourth track segment A1322 can be considered to extend from the intersection center A133 toward the fourth direction F4. At this time, the first sliding member A141 is located at the intersection center A133, and the second sliding member A142 is located at the second track segment A1312. In this way, the first positioning assembly A110 rotates and slides relative to the second positioning assembly A120 with the help of the first sliding member A141 sliding along the second track A132 and the second sliding member A142 sliding along the first track A131.

[0223] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding 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, when the first sliding component A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding component A142 is arranged behind the first sliding component A141.

[0224] In the positioning assembly A100 provided in the fifth embodiment, as shown in FIG24 , the first positioning assembly A110 may include a first top cover A111 and a first bottom cover A112, and the first top cover A111 and the first bottom cover A112 are connected to each other up and down to form a first mounting cavity (not shown in the figure). FIG26 to FIG29 show top views of the positioning assembly A100 when the first positioning assembly A110 is oriented in different directions relative to the second positioning assembly A120. In order to clearly understand the principle of the first positioning assembly A110 rotating and sliding relative to the second positioning assembly A120, the first positioning assembly A110 shown in FIG26 to FIG29 only retains the first bottom cover A112.

[0225] As shown in Figures 25 and 26, when the first sliding member A141 is arranged at the positioning axis of the second positioning component A120, and the second sliding member A142 is arranged behind the first sliding member A141 along the first direction F1, when the first positioning component A110 is arranged relative to the second positioning component A120 toward the first direction F1, the first sliding member A141 is located at the intersection center A133, that is, point M or point N', and the second sliding member A142 is located at the end of the second track segment A1312 away from the intersection center A133, that is, point N.

[0226] When the user needs to switch the first positioning component A110 from being set in the first direction F1 to being set in the second direction F2 relative to the second positioning component A120, it is equivalent to changing the carrier body A200 from being set in the front to being set in the left. As shown in Figures 24 and 25, the user can directly pull the carrier body A200 to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the first sliding member A141 can switch from point M to point M” in the fourth track segment A1322 relative to the first positioning component A110, and at the same time, the second sliding member A142 can switch from point N to point N’ in the second track segment A1312 relative to the first positioning component A110 (switch from Figure 26 to Figure 27). This During the process, the first positioning assembly A110 gradually begins to rotate relative to the second positioning assembly A120, and at the same time can move forward and backward relative to the second positioning assembly A120 along the front-to-rear direction of the vehicle (specifically, move backward, move along the third direction F3) to protrude from the rear end edge of the second positioning assembly A120 (see Figure 27). When the first sliding member A141 moves relatively to point M", the second sliding member A142 is located at point N', that is, the intersection center A133. At this time, the first positioning assembly A110 is oriented in the second direction F2 relative to the second positioning assembly A120, and the first positioning assembly A110 is pulled outward relative to the second positioning assembly A120 along the third direction F3. It should be noted that when the first positioning assembly A110 is rotated to face the second direction F2, at this time, as shown in Figure 27, the first rail segment A1311 can be regarded as extending from the intersection center A133 to the second direction F2, the second rail segment A1312 can be regarded as extending from the intersection center A133 to the fourth direction F4, the third rail segment A1321 can be regarded as extending from the intersection center A133 to the third direction F3, and the fourth rail segment A1322 can be regarded 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 being set in the second direction F2 to being set in the third direction F3, it is equivalent to changing the carrier body A200 from being set in the left direction to being set in the rear direction. As shown in Figures 24 and 25, the user can directly pull the carrier body A200 to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the second sliding member A142 in the first track segment A1311 relative to the first positioning component A110 can be switched from point N' to point N". At the same time, the position of the first sliding member A141 in the fourth track segment A1322 relative to the first positioning component A110 is synchronously switched from point M" to point M (from Figure 27 to Figure 28). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time can move forward and backward relative to the second positioning component A120 along the front and rear directions of the automobile (specifically, it moves from the rear end edge of the second positioning component A120 to the position of the first sliding member A141, that is, moves along the first direction F1). In this way, when the first positioning component A110 is rotated to the third direction F3 relative to the second positioning component A120, its orthographic projection position on the second positioning component A120 is the same as the orthographic projection position of the first positioning component A110 on the second positioning component A120 when it is rotated to the first direction F1 relative to the second positioning component A120 (see Figures 26 and 28). When the second sliding member A142 moves relatively to point N", the first sliding member A141 is located at point M, that is, the intersection center A133. At this time, the first positioning component A110 is oriented in 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 shown in Figure 28, the first rail segment A1311 can be regarded as extending from the intersection center A133 to the third direction F3, the second rail segment A1312 can be regarded as extending from the intersection center A133 to the first direction F1, the third rail segment A1321 can be regarded as extending from the intersection center A133 to the fourth direction F4, and the fourth rail segment A1322 can be regarded as extending from the intersection center A133 to the second direction F2.

[0228] Furthermore, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the third direction F3 to being set in the fourth direction F4, it is equivalent to changing the carrier body A200 from being set in the rear direction to being set in the right direction. As shown in Figures 24 and 25, the carrier body A200 is pulled to cause the carrier body A200 to drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 The second track A132 will rotate simultaneously with the first positioning component A110, so that the first sliding member A141 can switch from point M to point M' relative to the first positioning component A110 in the third track segment A1321, so that the second sliding member A142 can synchronously switch from point N" to point N' relative to the first positioning component A110 in the first track segment A1311 (from Figure 28 to Figure 29). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can The second positioning assembly A120 is moved forward and backward along the front-to-back direction of the vehicle (specifically, moved backward, i.e., moved along the third direction F3) so as to protrude from the rear end edge of the second positioning assembly A120 (see FIG29 ). When the first sliding member A141 moves relatively to point M', the second sliding member A142 is located at point N', i.e., the intersection center A133. At this time, the first positioning assembly A110 is oriented relative to the second positioning assembly A120 in the fourth direction F4. The first positioning assembly A110 is oriented relative to the second positioning assembly A120 in the fourth direction F4. It should be noted that when the first positioning assembly A110 is rotated to face the fourth direction F4, as shown in FIG29 , the first rail segment A1311 can be considered to extend from the intersection center A133 toward the fourth direction F4, the second rail segment A1312 can be considered to extend from the intersection center A133 toward the second direction F2, the third rail segment A1321 can be considered to extend from the intersection center A133 toward the first direction F1, and the fourth rail segment A1322 can be considered to extend from the intersection center A133 toward 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 being set in the fourth direction F4 to being set in the first direction F1, it is equivalent to changing the carrier body A200 from being set in the right direction to being set in the front direction. The carrier body A200 is directly pulled to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the second sliding member A142 can switch from point N' to point N in the second track segment A1312 relative to the first positioning component A110, so that the first sliding member A141 can synchronously switch from point M' to point M in the first track segment A1311 relative to the first positioning component A110 (switch from Figure 29 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 can move forward and backward relative to the second positioning component A120 along the front and rear directions of the car (specifically, from the rear end edge of the second positioning component A120 to the position of the first sliding member A141, that is, moving along the first direction F1) to reset.

[0230] Similarly, it should be noted that when the first sliding member A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding member A142 is arranged behind the first sliding member A141, the switching process of the first positioning component A110 relative to the second positioning component A120 toward the first direction F1 and the second direction F2 is reversible, and the switching process toward the second direction F2 and the third direction F3 is reversible. At the same time, the switching process toward the third direction F3 and the fourth direction F4 is reversible, and the switching process toward the fourth direction F4 and the first direction F1 is also reversible.

[0231] Similarly, it should be noted that the above description uses the process of the first positioning assembly A110 rotating one revolution counterclockwise relative to the second positioning assembly A120 as an example to illustrate the principle of simultaneous rotation and sliding. Of course, the process of the first positioning assembly A110 rotating one revolution clockwise relative to the second positioning assembly A120 can also be used as an example to illustrate the principle of simultaneous rotation and sliding, and this description will not be repeated here.

[0232] Referring to Figures 24 and 30 , a sixth embodiment of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of the positioning assembly A100 of the fifth embodiment, differing primarily in the position of the second sliding member A142. Therefore, unless otherwise noted, the following primarily describes the differences between this embodiment and the fifth embodiment.

[0233] Specifically, in the sixth embodiment, with respect to the second positioning assembly A120, when the first sliding member A141 is disposed at the positioning axis, the second sliding member A142 can also be disposed in front of the first sliding member A141 (see FIG30 ), that is, the second sliding member A142 is disposed on one side of the first sliding member A141 along the first direction F1. When the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120, the first sliding member A141 is located at the intersection center A133, and the second sliding member A142 is located at the first track segment A1311. In this way, the first positioning assembly A110 can also rotate and slide relative to the second positioning assembly A120 with the help of the first sliding member A141 sliding along the second track A132 and the second sliding member A142 sliding along the first track A131.

[0234] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding 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, when the first sliding component A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding component A142 is arranged in front of the first sliding component A141.

[0235] Specifically, when the first sliding member A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding member A142 is arranged in front of the first sliding member A141, when the first positioning component A110 is set in the first direction F1 relative to the second positioning component A120, the first sliding member A141 is located at the intersection center A133, that is, 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, that is, point N" (see Figure 26).

[0236] When the user needs to switch the first positioning assembly A110 relative to the second positioning assembly A120 from being oriented in the first direction F1 to being oriented in the second direction F2, this is equivalent to changing the carrier body A200 from being oriented forward to being oriented to the left. As shown in Figures 24 and 30, the user can pull the carrier body A200, causing it to move the first positioning assembly A110, causing it to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the first sliding member A141 can switch from point M to point M' relative to the position of the first positioning component A110 in the second track segment A1312, and at the same time, the second sliding member A142 can switch from point N" to point N' relative to the position of the first positioning component A110 in the first track segment A1311 (from Figure 26 to Figure 31). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can also switch relative to the second positioning component A120. 120 moves forward and backward along the front-to-back direction of the vehicle (specifically, forward, in the first direction F1), allowing the first positioning assembly A110 to protrude beyond the front edge of the second positioning assembly A120 along the first direction F1 (see FIG31 ). When the first sliding member A141 moves relative to each other to point M', the second sliding member A142 is located at point N', i.e., the intersection center A133. At this point, the first positioning assembly A110 is oriented in the second direction F2 relative to the second positioning assembly A120, and the first positioning assembly A110 is pulled outward relative to the second positioning assembly A120 along the first direction F1.

[0237] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the second direction F2 to being set in the third direction F3, it is equivalent to changing the carrier body A200 from being set in the left direction to being set in the rear direction, as shown in Figures 24 and 30. The user can directly pull the carrier body A200 to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the second sliding member A142 in the second track segment A1312 is switched from point N' to point N. At the same time, the position of the first sliding member A141 in the third track segment A1321 is synchronously switched from point M' to point M (switch from Figure 31 to Figure 28). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and can simultaneously move relative to the second positioning component A120 along the front-to-back direction of the vehicle (specifically, from the front edge of the second positioning component A120 to the position of the first sliding member A141, 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 of the first positioning component A110 on the second positioning component A120 when it rotates relative to the second positioning component A120 to the first direction F1 (see Figures 26 and 28). When the second sliding member A142 moves to point N, the first sliding member A141 is located at point M, i.e., the intersection center A133. At this time, the first positioning component A110 is oriented relative to the second positioning component A120 in the third direction F3.

[0238] Furthermore, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the third direction F3 to being set in the fourth direction F4, it is equivalent to changing the carrier body A200 from being set in the rear direction to being set in the right direction, as shown in Figures 24 and 30. The carrier body A200 is pulled to cause the carrier body A200 to drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the first sliding member A141 in the fourth track segment A1322 is switched from point M to point M", so that the position of the second sliding member A142 in the second track segment A1312 is switched from point N to point M". Switch from point M to point N' (switch from Figure 28 to Figure 32). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time can move forward and backward relative to the second positioning component A120 along the front and rear directions of the automobile (specifically, move forward, the first direction F1), so that the first positioning component A110 can protrude from the partial edge of the front end of the second positioning component A120 along the first direction F1 (see Figure 32). When the first sliding member A141 moves relatively to M", the second sliding member A142 is located at point N', that is, 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 pulled outward relative to the second positioning component A120 along the first direction F1. Similarly, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the fourth direction F4 to being set in the first direction F1, it is equivalent to changing the carrier body A200 from being set in the right direction to being set in the front direction. The carrier body A200 is directly pulled to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the second sliding member A142 in the first track segment A1311 is switched from point N' to point N", so that the position of the first sliding member A141 in the second track segment A1312 is synchronously switched from point M" to point M (switched 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 can move forward and backward relative to the second positioning component A120 along the front and rear directions of the car (specifically, from the front end edge of the second positioning component A120 to the position of the first sliding member A141, the third direction F3) to reset.

[0239] Similarly, when the first sliding member A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding member A142 is arranged in front of the first sliding member A141, the switching process of the first positioning component A110 relative to the second positioning component A120 toward the first direction F1 and the second direction F2 is reversible, and the switching process toward the second direction F2 and the third direction F3 is reversible. At the same time, the switching process toward the third direction F3 and the fourth direction F4 is reversible, and the switching process toward the fourth direction F4 and the first direction F1 is also reversible.

[0240] According to the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 in the above-mentioned situation, 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 car (see Figures 31 and 32). Taking a seven-seater car as an example, the rear door of the car is usually installed on the second row of seats. In this way, for example, when the carrier body A200 is installed on the third row of seats through the positioning component A100, the carrier body A200 can reduce the distance between the carrier body A200 and the rear door when it rotates with the first positioning component A110 to face the left or right side, that is, the second direction F2 or the fourth direction F4. This makes it convenient for users to place children into the carrier body A200 or take children out of the carrier body A200 at the rear door.

[0241] Referring to Figures 24 and 33 , a seventh embodiment of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of the positioning assembly A100 of the fifth embodiment, differing primarily in the position of the second sliding member A142. Therefore, unless otherwise noted, the following primarily describes the differences between this embodiment and the fifth embodiment.

[0242] Specifically, in the seventh embodiment, with respect to the second positioning assembly A120, when the first sliding member A141 is positioned at the positioning axis, the second sliding member A142 can be positioned to the left of the first sliding member A141 (see FIG. 33 ), that is, the second sliding member A142 is positioned on one side of the first sliding member A141 along the second direction F2. When the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120, the first sliding member A141 is positioned at the intersection center A133, and at this time, the second sliding member A142 is positioned at the third track segment A1321. In this way, the first positioning assembly A110 can rotate and slide relative to the second positioning assembly A120 with the first sliding member A141 sliding along the first track A131 and the second sliding member A142 sliding along the second track A132.

[0243] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding relative to the second positioning component A120 under the action of the first sliding component A141 sliding along the first track A131 and the second sliding component A142 sliding along the second track A132, when the first sliding component A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding component A142 is arranged to the left of the first sliding component A141 (that is, the second sliding component A142 is located on the side of the first sliding component A141 along the second direction F2).

[0244] Specifically, when the first sliding member A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding member A142 is arranged on the left side of the first sliding member A141 along the first direction F1, when the first positioning component A110 is arranged relative to the second positioning component A120 toward the first direction F1, the first sliding member A141 is located at the intersection center A133, that is, point M or point N', and the second sliding member A142 is located at the end of the third rail segment A1321 away from the intersection center A133, that is, point M'.

[0245] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the first direction F1 to being set in the second direction F2, it is equivalent to changing the carrier body A200 from being set in the front to being set in the left direction. As shown in Figures 24 and 33, the user can directly pull the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the first sliding member A141 in the third track segment A1321 switches from point M (i.e., point N') to point N, and at the same time, the position of the second sliding member A142 in the second track segment A1312 is synchronously switched from point M' to point M (i.e., point N') (switching from Figure 26 to Figure 34). During this process, the first positioning assembly A110 gradually begins to rotate relative to the second positioning assembly A120, while simultaneously moving laterally relative to the second positioning assembly A120 in the fore-and-aft direction of the vehicle (specifically, in the left direction, the second direction F2), protruding beyond the left edge of the second positioning assembly A120 (see FIG. 34 ), thereby being pulled outward. When the first sliding member A141 moves relative to point N, the second sliding member A142 is located at point M (i.e., point N'), i.e., at the intersection center A133. At this point, the first positioning assembly A110 is oriented in the second direction F2 relative to the second positioning assembly A120, and the first positioning assembly A110 is pulled outward relative to the second positioning assembly A120 in the second direction F2.

[0246] When the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set toward the second direction F2 to being set toward the third direction F3, it is equivalent to changing the carrier body A200 from being set toward the left to being set toward the rear, as shown in Figures 24 and 33. The user can pull the carrier body A200 to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the second sliding member A142 in the fourth track segment A1322 is switched from point M (i.e., point N') to point M". , the position of the first sliding member A141 in the second rail segment A1312 is synchronously switched from point N to point M (i.e., point N') (switched from Figure 34 to 28). 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 left direction) relative to the second positioning component A120 toward the position where the first sliding member A141 is located (i.e., toward the positioning axis). When the second sliding member A142 moves relatively to point M", the first sliding member A141 is located at point M (i.e., point N'), i.e., 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 first positioning component A110 relative to the second positioning component A120 from being set in the third direction F3 to being set in the fourth direction F4, it is equivalent to changing the carrier body A200 from being set towards the rear to being set towards the right, as shown in Figures 24 and 33. Pull the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the first sliding member A141 in the first track segment A1311 is switched from point M (i.e., point N') to point N", so that the position of the second sliding member A142 in the fourth track segment A1322 is synchronously switched from point M" to point M (i.e., point N') (switch from Figure 28 to Figure 35). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time can move laterally relative to the second positioning component A120 along the front and rear direction of the car (specifically, move along 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 35), that is, retract inward along the right side. When the first sliding member A141 moves to point N", the second sliding member A142 is located at point M (i.e., 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 the right side to facing the first direction F1. It is changed to be set forward, and the carrier body A200 is directly pulled, so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the second sliding member A142 in the third track segment A1321 is switched from point M (i.e. point N') to point M', so that the position of the first sliding member A141 in the first track segment A1311 is synchronously switched from point N" to point M (i.e. point N') (switched from Figure 35 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 from the lateral direction (specifically the left direction) relative to the second positioning component A120 to the position where the first sliding member A141 is located (which can be regarded as the positioning axis).

[0248] Similarly, when the first sliding member A141 is arranged at the rotation axis of the second positioning component A120 and the second sliding member A142 is arranged to the left of the first sliding member A141, the switching process of the first positioning component A110 relative to the second positioning component A120 between the first direction F1 and the second direction F2 is reversible, and the switching process between the second direction F2 and the third direction F3 is reversible. At the same time, the switching process between the third direction F3 and the fourth direction F4 is reversible, and the switching process between the fourth direction F4 and the first direction F1 is also reversible.

[0249] According to the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 in the situation described above, it can be known that: when the first positioning component A110 rotates from the first direction F1 or the third direction F3 to the second direction F2 or the fourth direction F4 relative to the second positioning component A120, the first positioning component A110 can rotate relative to the second positioning component A120 to change its direction, and 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 eliminated, that is, the first track A131 only includes the second track segment A1312. At this time, when the first positioning component A110 rotates from the first direction F1 or the third direction F3 to the second direction F2 relative to the second positioning component A120, the first positioning component A110 can be pulled outward along the second direction F2 relative to the second positioning component A120. In this way, the carrier body A200 connected to the first positioning component A110 can be closer to the vehicle door when it rotates to the second direction F2 with the first positioning component A110, thereby making it convenient for the user to pick up the child from the carrier body A200 or put the child into the carrier body A200. Similarly, in other embodiments, the second rail segment A1312 can be selectively eliminated, that is, the first track A131 only includes the first rail segment A1311. In this case, when the first positioning assembly A110 rotates relative to the second positioning assembly A120 from the first direction F1 or the third direction F3 to the fourth direction F4, the first positioning assembly A110 can rotate relative to the second positioning assembly A120 to change its direction, and can also retract inward along the fourth direction F4 relative to the second positioning assembly A120 to move away from the vehicle door. When a child rides in the carrier body A200 that is set sideways (specifically, set toward the right vehicle door), this can prevent the child from hitting the vehicle door when the carrier body A200 is turned to the sideways position, and can also provide a larger space for the child's feet in the sideways position. In addition, since there is no need to turn the carrier body first and then pull it outward or push it inward laterally as in the traditional method, the convenience of operation is improved.

[0250] Referring to Figures 24 and 36 , the eighth embodiment of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of the positioning assembly A100 of the fifth embodiment, differing primarily in the position of the second sliding member A142. Therefore, unless otherwise specified, the following description will primarily focus on the differences between this embodiment and the fifth embodiment.

[0251] Specifically, in the eighth embodiment, with respect to the second positioning assembly A120, when the first sliding member A141 is disposed at the positioning axis, the second sliding member A142 can also be disposed to the right of the first sliding member A141 (see FIG. 36 ), that is, the second sliding member A142 is located on one side of the first sliding member A141 along the fourth direction F4. When the first positioning assembly A110 is oriented in the first direction F1 relative to the second positioning assembly A120, the first sliding member A141 is located at the intersection center A133, and the second sliding member A142 is located at the fourth track segment A1322. In this way, the first positioning assembly A110 can also rotate and slide relative to the second positioning assembly A120 with the help of the first sliding member A141 sliding along the first track A131 and the second sliding member A142 sliding along the second track A132.

[0252] The following, in conjunction with relevant illustrations, briefly explains the principle and process of the first positioning component A110 in the positioning component A100 rotating and sliding 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, when the first sliding component A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding component A142 is arranged to the right of the first sliding component A141 (that is, the second sliding component A142 is located on the side of the first sliding component A141 along the fourth direction F4).

[0253] Specifically, when the first sliding member A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding member A142 is arranged to the right of the first sliding member A141, when the first positioning component A110 is arranged in the first direction F1 relative to the second positioning component A120, the first sliding member A141 is located at the intersection center A133, that is, point M or point N', and the second sliding member A142 is located at the end of the fourth rail segment A1322 away from the intersection center A133, that is, 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 being set in the first direction F1 to being set in the second direction F2, it is equivalent to changing the carrier body A200 from being set in the front to being set in the left direction. As shown in Figures 24 and 36, the user can directly pull the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the first sliding member A141 in the first track segment A1311 switches from point M or point N' to point N", and at the same time, the position of the second sliding member A142 in the fourth track segment A1322 is synchronously switched from point M" to point M or N' (switch from Figure 26 to Figure 37). During this process, the first positioning component A110 gradually begins to rotate relative to the second positioning component A120, and at the same time can move laterally relative to the second positioning component A120 along the front-to-rear direction of the automobile (specifically, move along the right direction, the 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, retract inward along the left side. When the first sliding member A141 moves to point N", the second sliding member 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 in the second direction F2 relative to the second positioning component A120, and the first positioning component A110 is retracted 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 being set in the second direction F2 to being set in the third direction F3, it is equivalent to changing the carrier body A200 from being set in the left direction to being set in the rear direction, as shown in Figures 24 and 36. The user can pull the carrier body A200 to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the second sliding member A142 in the third track segment A1321 is switched from point M or point N' to point M', and at the same time, the position of the first sliding member A141 in the first track segment A1311 is synchronously switched from point N" to point M or point N' (switched from Figure 37). To Figure 28). 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 from the lateral direction (specifically the right direction) relative to the second positioning component A120 to the position where the first sliding member A141 is located (i.e., toward the positioning axis). In this way, when the first positioning component A110 rotates to the third direction F3 relative to the second positioning component A120, its orthographic projection on the second positioning component A120 is the same as the position of the orthographic projection of the first positioning component A110 rotated to the first direction F1 relative to the second positioning component A120. When the second sliding member A142 moves relatively to point M', the first sliding member A141 is located at point M or point N', i.e., 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.

[0256] Furthermore, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the third direction F3 to being set in the fourth direction F4, it is equivalent to changing the carrier body A200 from being set towards the rear to being set towards the right, as shown in Figures 24 and 36. Pull the carrier body A200 so that the carrier body A200 drives the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that the position of the first sliding member A141 in the second track segment A1312 is switched from point M or point N' to point N, so that the position of the second sliding member A142 in the third track segment A1321 is synchronously switched from point M' to point M or point N' (switch from Figure 28 to Figure 38). During this process, first positioning assembly A110 gradually begins to rotate relative to second positioning assembly A120, while simultaneously moving laterally relative to second positioning assembly A120 in the fore-and-aft direction of the vehicle (specifically, in the right direction, i.e., fourth direction F4), thereby protruding relative to the right edge of second positioning assembly A120 (see FIG. 38 ), i.e., being pulled to the right. When first slider A141 moves to point N, second slider A142 is located at point M or N', i.e., intersection center A133. At this point, first positioning assembly A110 is oriented in fourth direction F4 relative to second positioning assembly A120, and first positioning assembly A110 is pulled outward relative to second positioning assembly A120 in fourth direction F4. Similarly, when the user needs to switch the first positioning component A110 relative to the second positioning component A120 from being set in the fourth direction F4 to being set in the first direction F1, it is equivalent to changing the carrier body A200 from being set in the right direction to being set in the front direction. The carrier body A200 is directly pulled to make the carrier body A200 drive the first positioning component A110 to move, so that the first positioning component A110 has a tendency to rotate counterclockwise. In this way, the first track A131 and the second track A132 will rotate simultaneously with the first positioning component A110, so that The position of the second sliding member A142 in the fourth rail segment A1322 is switched from point M or point N' to point M", so that the position of the first sliding member A141 in the second rail segment A1312 is synchronously switched from point N to point M or point N' (switching from Figure 38 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, the first positioning component A110 moves from the lateral direction (specifically the right direction) relative to the second positioning component A120 to the position where the first sliding member A141 is located (which can be regarded as the positioning axis) for reset.

[0257] It should be noted that, when the first sliding member A141 is arranged at the positioning axis of the second positioning component A120 and the second sliding member A142 is arranged to the right of the first sliding member A141, the switching process of the first positioning component A110 relative to the second positioning component A120 toward the first direction F1 and the second direction F2 is reversible, and the switching process toward the second direction F2 and the third direction F3 is reversible. At the same time, the switching process toward the third direction F3 and the fourth direction F4 is reversible, and the switching process toward the fourth direction F4 and the first direction F1 is also reversible.

[0258] According to the principle and process of the rotation and sliding of the first positioning component A110 relative to the second positioning component A120 in the situation described above, it can be known that: when the first positioning component A110 rotates from the first direction F1 or the third direction F3 to the second direction F2 or the fourth direction F4 relative to the second positioning component A120, the first positioning component A110 can rotate relative to the second positioning component A120 to change its direction, and 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 eliminated, that is, the first track A131 only includes the first track segment A1311. At this time, when the first positioning component A110 is rotated from the first direction F1 or the third direction F3 to the second direction F2 relative to the second positioning component A120, the first positioning component A110 can be retracted inward relative to the second positioning component A120 toward the second direction F2 to stay away from the vehicle door. When a child sits on the carrier body A200 that is set laterally (specifically, set toward the left vehicle door), this can prevent the child from hitting the vehicle door when turning to the sideways use state, and can also provide a larger space for placing the feet in the sideways use state. Similarly, in other embodiments, the first track segment A1311 can be selectively eliminated, that is, the first track A131 only includes the second track segment A1312. In this case, when the first positioning assembly A110 rotates relative to the second positioning assembly A120 from the first direction F1 or the third direction F3 to the fourth direction F4, the first positioning assembly A110 can rotate relative to the second positioning assembly A120 to change its orientation. At the same time, it can also be pulled outward relative to the second positioning assembly A120 along the fourth direction F4 to approach the vehicle door. In this way, the carrier body A200 connected to the first positioning assembly A110 can be closer to the vehicle door, making it easier for the user to pick up a child from the carrier body A200 or place the child in the carrier body A200. In addition, since there is no need to first turn and then pull outward or push inward laterally as in the traditional method, the convenience of operation is improved. Of course, in some other embodiments not shown, the first rail segment A1311 and the second rail segment A1312 may be retained, and the positioning assembly A100 may further include a blocking mechanism (see below). The blocking mechanism may be provided on the movement path of the first sliding member A141 along the first rail segment A1311 to restrict the first positioning assembly A110 from rotating relative to the second positioning assembly A120 from the first direction F1 or the third direction F3 to the second direction F2. In this way, the carrier body A200 can only rotate with the first positioning assembly A110 to the fourth direction F4 to be pulled outward toward the right side, thereby improving the convenience of taking and placing the child sideways (specifically toward the right side).Alternatively, the blocking mechanism can also be arranged on the moving path of the first sliding member A141 along the second rail segment A1312 to limit the first positioning component A110 from rotating from the first direction F1 or the third direction F3 to the fourth direction F4 relative to the second positioning component A120. In this way, the carrier body A200 can only rotate with the first positioning component A110 to the second direction F2 to retract inward toward the left side, so as to avoid hitting the left door when the carrier body A200 is used sideways (specifically toward the left side), while increasing the space for placing the feet when used sideways.

[0259] As can be seen from the above description, in the fifth to eighth embodiments, when the first sliding member A141 is disposed at the positioning axis of the second positioning assembly A120, the second sliding member A142 can be disposed in front of, behind, to the left of, or to the right of the first sliding member A141. In each embodiment, the first positioning assembly A110 can simultaneously slide while rotating relative to the second positioning assembly A120. This improves user convenience.

[0260] It should be noted that the "first sliding member A141" and the "second sliding member A142" in each embodiment of the first aspect can be collectively referred to as a sliding assembly. In addition, it should be noted that in each embodiment of this aspect, when the first positioning assembly A110 protrudes toward one side (such as the left or right side) of the second positioning assembly A120 relative to the second positioning assembly A120, the first positioning assembly A110 is displaced toward one side relative to the geometric center of the second positioning assembly A120, and the vehicle body A200 can also be regarded as being displaced laterally relative to the second positioning assembly A120, so that the front end of the vehicle body A200 (the position where the child's feet are placed) is closer to the side door. When the first positioning component A110 is retracted relative to the second positioning component A120 toward one side of the second positioning component A120 (such as the left side or the right side), the geometric center of the first positioning component A110 is displaced relative to the second positioning component A120 toward the other side opposite to the one side, and the carrier body A200 will also be laterally retracted relative to the second positioning component A120 so that the front end of the carrier body A200 (the position where the child's feet are placed) is away from the side door.

[0261] The second aspect of the present invention provides a carrier A1000, which includes a carrier body A200 and a positioning assembly A100 provided in some embodiments of the present invention, wherein the carrier body A200 can be fixedly mounted on the positioning assembly A100; of course, the carrier body A200 can also be detachably mounted on the positioning assembly A100. In the carrier A1000 provided in this embodiment, the carrier body A200 is the same as the carrier body A200 in the carrier A1000 provided in the embodiment described above. The positioning assembly A100 is similar to the positioning assembly A100 in the embodiment described above, and includes components such as a first positioning assembly A110 and a second positioning assembly A120. Specifically, the positioning assembly A100 in this embodiment can be regarded as a deformation of the positioning assembly A100 described above. Therefore, in the absence of conflict, the structures of the first positioning assembly A110, the second positioning assembly A120 and other components in this embodiment and the connection relationship between the components 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 assembly A100 also includes a first positioning assembly A110 and a second positioning assembly A120. The first positioning assembly A110 is used to connect to the carrier body A200; the second positioning assembly A120 is used to connect to the car seat. One of the first positioning assembly A110 and the second positioning assembly A120 is provided with a first track A131 and a second track A132, and the other is provided with a sliding assembly A143. For example, the first positioning assembly A110 is provided with a first track A131 and a second track A132, and the second positioning assembly A120 is provided with a sliding assembly A143. Specifically, the first track A131 intersects with the second track A132, and the sliding assembly A143 can rotate within the first track A131 and slide within the second track A132. The first positioning assembly A110 rotates in the first track A131 with the aid of the sliding assembly A143 to rotate relative to the second positioning assembly A120, and slides in the second track A132 with the aid of the sliding assembly A143 to slide relative to the second positioning assembly A120. More specifically, in this embodiment, the first positioning assembly A110 is provided with a sliding assembly A143, and the second positioning assembly A120 is provided with a first track A131 and a second track A132. The first track A131 and the second track A132 are connected at the intersection, and the sliding assembly A143 is capable of sliding continuously between the first track A131 and the second track A132. It should be noted that "continuous sliding" means that the sliding assembly A143 moves between the first track A131 and the second track A132 in a continuous manner along the direction of the track. This movement can be a back-and-forth shuttle between the two tracks, or a continuous one-way or reciprocating motion between the two tracks along a certain direction.

[0263] Referring to Figures 39 and 40, in the positioning assembly A100 provided in the first embodiment of the second aspect, the first positioning assembly A110 is provided with a sliding assembly A143, and the second positioning assembly A120 is provided with a first track A131 and a second track A132. Among them, the first track A131 includes a first channel A1313, the first channel A1313 is a circular structure, and the center of the first channel A1313 can coincide with or be offset from the geometric center of the second positioning assembly A120. Specifically, the center of the first channel A1313 coincides with the geometric center of the second positioning assembly A120, and when the first positioning assembly A110 is installed on the second positioning assembly A120 and the sliding assembly A143 is located in the first channel A1313, the center of the first channel A1313 is coaxial with the center of the first positioning assembly A110. The second track A132 extends along the second direction F2 or the fourth direction F4 (i.e., away from the second direction F2). Specifically, the second track A132 includes a second channel A1323, which is a bar-shaped structure. The first channel A1313 and the second channel A1323 are connected at the intersection. Specifically, the sliding assembly A143 includes a slider A1432, which is connected to the first positioning assembly A110 and can rotate within the first channel A1313 and slide within the second channel A1323. More specifically, in this embodiment, the first channel A1313 and the second channel A1323 can be regarded as groove structures provided on the upper surface of the second top cover A121.

[0264] Continuing with Figures 39 and 40, in one embodiment, the length L1 and width W1 of slider A1432 are both less than or equal to the diameter D of first channel A1313, allowing slider A1432 to rotate within first channel A1313. The length L1 of slider A1432 is greater than the width W2 of second channel A1323, and the width W1 of slider A1432 is less than or equal to the width W2 of second channel A1323, allowing slider A1432 to slide within second channel A1323 while restricting rotation within second channel A1323. Thus, the orientation of first positioning assembly A110 relative to second positioning assembly A120 can be changed by the slider A1432 rotating within 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 to 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 by the first channel A1313 into a third track segment A1321 and a fourth track segment A1322, each of which is connected to the first channel A1313. The third track segment A1321 extends from the first channel A1313 in the second direction F2, and the fourth track segment A1322 extends from the first channel A1313 in the fourth direction F4. When the first positioning assembly A110 rotates relative to the second positioning assembly A120 to face the second direction F2 or the fourth direction F4, the length of the slider A1432 becomes parallel to the second direction F2.

[0266] Referring to Figures 39 and 40, when the slider A1432 is located in the first channel A1313, the slider A1432 can rotate in the first channel A1313, so that the first positioning component A110 can 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 rail segment A1321 extends from the first channel A1313 toward the second direction F2, and the fourth rail segment A1322 extends from the first channel A1313 toward the fourth direction F4, when the first positioning component A110 is rotated relative to the second positioning component A120 to face the second direction F2 or the fourth direction F4, the slider A1432 can be driven from the first channel A1313 to the third rail segment A1321 or the fourth rail segment A1322 by pushing or pulling the first positioning component A110. Specifically, for example, when the first positioning assembly A110 rotates relative to the second positioning assembly A120 to face the second direction F2, the first positioning assembly A110 can be moved inward in a direction opposite to the second direction F2 by directly pushing the carrier body A200, so that the slider A1432 enters the fourth track segment A1322. In this way, when the carrier body A200 is connected to the first positioning assembly A110, the distance between the front end of the carrier body A200 and the left door can be increased (compare Figures 41 and 42). When the carrier body A200 rotates relative to the second positioning assembly A110 to face the second direction F2, the front end of the carrier body A200 can be prevented from hitting the left door. In addition, when a child rides on the sideways-mounted carrier body A200, there is a larger space for placing their feet. Alternatively, when the first positioning component A110 is rotated relative to the second positioning component A120 to face the second direction F2, the carrier body A200 can be moved along the second direction F2 and protrude to the left by directly pulling the carrier body A200. In this way, when the carrier body A200 is connected to the first positioning component A110, the distance between the front end of the carrier body A200 and the left door can be shortened, thereby making it easier for the user to carry the child out of the carrier body A200 or place the child into the carrier body A200.

[0267] Referring to Figures 39, 43, and 44, a second embodiment of the second aspect of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of positioning assembly A100 in the first embodiment of the second aspect, differing primarily in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following primarily describes the differences between this embodiment and the first embodiment of the second aspect.

[0268] In this embodiment, as shown in FIG43 , the first track A131 includes a first channel A1313 and a first chute A1314, and the second track A132 includes a second channel A1323 and a second chute A1324. The structures of the first channel A1313 and the second channel A1323 can be found in the ninth embodiment, except that both the first channel A1313 and the second channel A1323 are disposed 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 chute A1314 is disposed on the second top cover A121 and located inside the first channel A1313, while the second chute A1324 is disposed on the second top cover A121 and located inside the second channel A1323. The second chute A1324 is connected to the first chute A1314 and extends along the direction in which the second channel A1323 extends, i.e., along the second direction F2 or the fourth direction F4. It should be noted that the first chute A1314 and the second chute A1324 are both through-groove 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 through the sliding rod A1431. The sliding rod A1431 passes through the first chute A1314 or the second chute A1324 to connect with the slider A1432, so that the sliding assembly A143 can rotate in the first track A131 and move in the second track A132 through the slider A1432. It should be noted that the width of the slider A1432 is respectively greater than the width of the first chute A1314 and the diameter of the second chute A1324 (see Figures 43 and 44). In this way, the slider A1432 can be confined in the second mounting cavity A123 to prevent the first positioning assembly A110 from disengaging from the second positioning assembly A120 when rotating or sliding relative to the second positioning assembly A120.

[0269] Referring to Figures 39 and 45 , the third embodiment of the second aspect of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of positioning assembly A100 of the ninth embodiment, differing primarily in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following primarily describes the differences between this embodiment and the first embodiment of the second aspect.

[0270] In this embodiment, as shown in FIG45 , the first track A131 includes a first channel A1313, the second track A132 includes a second channel A1323, and the second channel A1323 is a strip-shaped structure. The first channel A1313 and the second channel A1323 are both arranged on the upper surface of the second top cover A121. The difference is that the first channel A1313 is an annular structure, and the second channel A1323 passes through the first channel A1313 and is connected at the intersection. The sliding assembly A143 includes two sliders A144 32. The two sliders A1432 are both connected to the first positioning assembly A110 and are arranged opposite to each other. 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 to make the first positioning assembly A110 rotate relative to the second positioning assembly A120, and the two sliders A1432 can slide synchronously in the second channel A1323 to make the first positioning assembly A110 slide relative to the second positioning assembly A120.

[0271] Specifically, in this embodiment, the distance H1 between the sidewalls of the two sliders A1432 facing the center of the first channel A1313 is greater than or equal to the inner diameter D1 of the first channel A1313, allowing the two sliders A1432 to move synchronously within the first channel A1313, thereby allowing the first positioning assembly A110 to rotate relative to the second positioning assembly A120. More specifically, the distance H1 between the sidewalls of the two sliders A1432 facing the center of the first channel A1313 (i.e., the inner spacing) is greater than the width W2 of the second channel A1323, allowing the sliders A1432 to slide within the second channel A1323 while being restricted from rotating within the second channel A1323.

[0272] Continuing with FIG45 , specifically, in this embodiment, the second channel A1323 is divided by the first channel A1313 into a third track segment A1321, a fifth track segment A1325, and a fourth track segment A1322, which are arranged in sequence. The first channel A1313 is divided by the second channel A1323 into 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 in the first channel A1313 to change the orientation of the first positioning component A110 relative to the second positioning component A120, and can simultaneously move from the first channel A1313 to the second channel A1323 to change the position of the first positioning component A110 relative to the second positioning component A120.

[0273] Referring to Figures 39 and 46 , the fourth embodiment of the second aspect of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of the positioning assembly A100 of the third embodiment of the second aspect, differing primarily in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following primarily describes the differences between this embodiment and the third embodiment of the second aspect.

[0274] In this embodiment, as shown in FIG46 , the first track A131 includes a first channel A1313 and a first chute A1314, and the second track A132 includes a second channel A1323 and a second chute A1324. The structures of the first channel A1313 and the second channel A1323 can be referred to in the eleventh embodiment, except that both the first channel A1313 and the second channel A1323 are disposed on the lower surface of the second top cover A121. Specifically, the first chute A1314 is disposed on the second top cover A121 and is located inside the first channel A1313. Thus, the first chute A1314 can be considered an annular structure. The second chute A1324 is disposed on the second top cover A121 and is located inside the second channel A1323. The second chute A1324 is connected to the first chute 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 the first chute A1314 and the second chute A1324 are both through-groove structures. More specifically, the sliding assembly A143 also includes two sliding rods A1431 (see Figure 39). The two sliding rods A1431 are both connected to the first positioning assembly A110 and are connected to the two sliders A1432 after passing through the first chute A1314 or the second chute A1324. It should be noted that the width of the slider A1432 is respectively greater than the width of the first chute A1314 and the second chute A1324 (see Figure 46). In this way, the slider A1432 can be confined within the second mounting cavity A123 to prevent the first positioning assembly A110 from disengaging from the second positioning assembly A120 when rotating or sliding relative to the second positioning assembly A120.

[0275] Referring to Figures 39 and 47 , the fifth embodiment of the second aspect of the present invention provides a positioning assembly A100. This positioning assembly A100 can be considered a variation of the positioning assembly A100 of the fourth embodiment of the second aspect, differing primarily in the slightly different structures of the first track A131 and the second track A132. Similarly, unless otherwise specified, the following primarily describes the differences between this embodiment and the fourth embodiment of the second aspect.

[0276] In this embodiment, as shown in FIG47 , the first track A131 includes only a first chute A1314, which is an annular structure. The second track A132 includes only a second chute A1324, which is a strip-shaped structure. The first chute A1314 and the second chute A1324 are connected at the intersection. Specifically, the second chute A1324 is divided by the first chute A1314 to form a third track segment A1321, a fifth track segment A1325, and a fourth track segment A1322, which are arranged in sequence. The first chute A1314 is divided by the second chute 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. 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 shown in Figures 39 and 47, the sliding assembly A143 includes two sliders A1432 and two sliding rods A1431. The two sliding rods A1431 are both connected to the first positioning assembly A110 and are arranged opposite each other. The two sliding rods A1431 pass through the first sliding groove A1314 or the second sliding groove A1324 and are respectively connected to the two sliders A1432. The two sliding rods A1431 can slide simultaneously in the first sliding groove A1314 to rotate the first positioning component A110 relative to the second positioning component A120, and the two sliders A1432 can slide synchronously in the second sliding groove A1324 to slide the first positioning component A110 relative to the second positioning component A120 along the second direction F2 or the fourth direction F4.

[0277] From the above description, it can be seen that in the first to fifth embodiments of the second aspect, the first positioning component A110 shown in each embodiment can rotate and slide 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 toward one side (such as the left or right side) of the second positioning component A120 relative to the second positioning component A120, the first positioning component A110 is displaced toward one side relative to the geometric center of the second positioning component A120, and the vehicle body A200 can also be regarded as being displaced 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) is closer to the side door. When the first positioning component A110 is retracted relative to the second positioning component A120 toward one side of the second positioning component A120 (such as the left side or the right side), the geometric center of the first positioning component A110 is displaced relative to the second positioning component A120 toward the other side opposite to the one side, and the carrier body A200 will also be laterally retracted relative to the second positioning component A120 so that the front end of the carrier body A200 (the position where the child's feet are placed) is away from the side door.

[0278] An embodiment of the third aspect of the present invention provides a carrier A1000, which includes a carrier body A200 and a positioning assembly A100 provided in some embodiments of the present invention, wherein the carrier body A200 can be fixedly mounted on the positioning assembly A100; of course, the carrier body A200 can also be detachably mounted on the positioning assembly A100. In the carrier A1000 provided in this embodiment, the carrier body A200 is the same as the carrier body A200 provided in the embodiments described above. The positioning assembly A100 is similar to the positioning assembly A100 in the embodiments described above, and includes components such as a first positioning assembly A110 and a second positioning assembly A120. Among them, the first positioning assembly A110 can be rotated relative to the second positioning assembly A120, so that the first positioning assembly A110 can be rotated to various directions relative to the second positioning assembly A120, for example, the first direction F1, the second direction F2, the third direction F3 or the fourth direction F4. Specifically, the principle of the rotation of the first positioning assembly A110 relative to the second positioning assembly A120 can refer to any of the above embodiments. It should be noted that in this embodiment, the first positioning assembly A110 can rotate and slide relative to the second positioning assembly A120; alternatively, in this embodiment, the first positioning assembly A110 can only rotate relative to the second positioning assembly A120 and is limited to sliding relative to the second positioning assembly A120.

[0279] Referring to Figures 1 and 48, in this embodiment, the first top cover A111 of the first positioning assembly A110 is provided with a card slot A114. When the carrier body A200 is connected to the first positioning assembly A110, the card slot A114 is used to accommodate the engaging member A210 on the positioning assembly A100. More specifically, a through hole is provided inside the card slot A114, which is connected to the first mounting cavity (the cavity inside the first positioning assembly A110, that is, the cavity formed by the first top cover A111 and the first bottom cover A112). The engaging hook A151 is rotatably arranged in the first mounting cavity and can pass through the through hole to extend into the card slot A114. When the engaging hook A151 is in the locked position, the engaging hook A151 at least partially extends into the slot A114 to block the notch of the slot A114, so that the engaging member A210 can be confined within the slot A114. When the engaging hook A151 is in the unlocking position, the engaging hook A151 withdraws from the engaging slot A114 to open the notch of the engaging slot A114, so that the engaging member A210 can be disengaged from the engaging slot A114.

[0280] In one embodiment, the first connecting mechanism A150 may include two sets of latching hooks A151, and the carrier body A200 is provided with two latching members A210 (see Figures 1 and 48). The two latching members A210 are spaced apart along the Q1 direction or the Q3 direction of the carrier body A200. Correspondingly, the two sets of latching hooks A151 are spaced apart along the Q1 direction (or the Q3 direction) on the first positioning assembly A110. In this way, the two sets of latching hooks A151 can be used to lock or release the corresponding latching members A210. When the first positioning assembly A110 rotates relative to the second positioning assembly A120 toward the first direction F1 or the third direction F3, the Q1 direction and the Q3 direction are both parallel to the first direction F1 or the third direction F3. When the first positioning assembly A110 rotates relative to the second positioning assembly A120 toward the second direction F2 or the fourth direction F4, the Q1 direction and the Q3 direction are both parallel to the second direction F2 or the fourth direction F4. Specifically, when the two engaging parts A210 are locked by two groups of engaging hooks A151 at the same time, the stability and reliability of the carrier body A200 installed on the first positioning assembly A110 can be improved, and the carrier body A200 can be prevented from moving or rotating arbitrarily relative to the first positioning assembly A110. Of course, in other embodiments, the first connecting mechanism A150 may also include a group of engaging hooks A151, and an engaging part A210 is provided on the carrier body A200. It should be noted that, in this embodiment, a group of engaging hooks A151 may include one, two or more engaging hooks A151. When a group of engaging hooks A151 includes multiple engaging hooks A151, the multiple engaging 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 in the first direction F1 or the third direction F3 relative to the second positioning component A120, the Q2 direction and the Q4 direction are both parallel to the second direction F2 or the fourth direction F4 (see Figures 1 and 2); 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 Q2 direction and the Q4 direction are both parallel to the first direction F1 or the third direction F3 (see Figure 49). It should be noted that the Q1 direction refers to the forward direction along the front-to-back direction of the first positioning component A110 or the carrier body A200, the Q2 direction refers to the backward direction along the front-to-back direction of the first positioning component A110 or the carrier body A200, the Q3 direction refers to the left direction along the left-to-right direction of the first positioning component A110 or the carrier body A200, and the Q4 direction refers to the right direction along the left-to-right direction of the first positioning component A110 or the carrier body A200. The Q1 direction is parallel to and opposite to the Q3 direction, the Q2 direction is parallel to and opposite to the Q4 direction, and the Q1 direction and the Q2 direction are intertwined. Specifically, the Q1 direction and the Q2 direction are perpendicular.

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

[0282] Referring to Figures 48 and 49, specifically, in this embodiment, the principle that the two engaging parts A210 can be selectively locked to any two adjacent groups of engaging hooks A151 so that the carrier body A200 has a first usage state and a second usage state relative to the positioning component A100 can be simply explained by taking the carrier body A200 as an example where two engaging parts A210 are provided and the first connecting mechanism A150 includes three groups of engaging hooks A151.

[0283] In order to facilitate understanding of the engagement relationship between the two engaging parts A210 and the three sets of engaging hooks A151, the engaging part A210 close to the front end of the carrier body A200 is defined as the first engaging part A2101, and the engaging part A210 close to the rear end of the carrier body A200 is defined as the second engaging part A2102. Taking the situation where the first positioning assembly A110 is rotated relative to the second positioning assembly A120 to face the first direction F1 as a reference, the three groups of engaging hooks A151 on the first positioning assembly A110 are referred to as the first group of engaging hooks A1511, the second group of engaging hooks A1512, and the third group of engaging hooks A1513 along the Q3 direction of the first positioning assembly A110 (see FIG. 49 ). In other words, when the first positioning assembly A110 is facing the first direction F1, the first group of engaging hooks A1511 is located at the front end along the first direction F1 (or Q1 direction), that is, closer to the support leg A162, and the third group of engaging hooks A1513 is located at the rear end along the first direction F1 (or Q1 direction). When the first positioning assembly A110 is rotated relative to the second positioning assembly A120 to face the second direction F2, the first group of engaging hooks A1511 can be considered to be closest to the left door, and the third group of engaging hooks A1513 can be considered to be closest to the right door. Referring to Figures 48 to 50, in one embodiment, when the carrier body A200 is connected to the first positioning assembly A110 via the first connecting mechanism A150, the carrier body A200 and the first positioning assembly A110 can engage in the same direction, that is, the orientation of the carrier body A200 relative to the positioning assembly A100 is the same as the orientation of the first positioning assembly A110 relative to the second positioning assembly A120. For example, the first positioning assembly A110 and the carrier body A200 are oriented in the same direction F1, the second direction F2, the third direction F3, or the fourth direction F4. Therefore, when the carrier body A200 and the first positioning assembly A110 engage in the same direction, the first set of engaging hooks A1511 can be considered to be closer to the front end of the carrier body A200, and the third set of engaging hooks A1513 can be considered to be closer to the rear end of the carrier body A200.

[0284] Specifically, when the carrier body A200 is in the first usage state relative to the positioning assembly A100, the two engaging members A210 (i.e., the first engaging member A2101 and the second engaging member A2102) are respectively locked to the first two groups of engaging hooks A151 (i.e., the first group of engaging hooks A1511 and the second group of engaging hooks A1512) arranged near the front end of the first positioning assembly A110. For example, when the first positioning assembly A110 is rotated relative to the second positioning assembly A120 to face the second direction F2 (see Figure 49), and the carrier body A200 is facing the second direction F2 (see Figure 50), the first engaging member A2101 is locked to the first group of engaging hooks A1511, and the second engaging member A2102 is locked to the second group of engaging hooks A1512. At this time, the front end of the carrier body A200 protrudes outward relative to the first positioning assembly A110 along the direction of the carrier body A200 (i.e., the second direction F2) (not shown in the figure). For another example, when the first positioning assembly A110 rotates relative to the second positioning assembly A120 to face the fourth direction F4 (not shown), and the carrier body A200 faces the fourth direction F4, the first engaging member A2101 is locked to the first set of engaging hooks A1511, and the second engaging member A2102 is locked to the second set of engaging hooks A1512. At this time, the front end of the carrier body A200 protrudes outward relative to the first positioning assembly A110 along the direction of the carrier body A200 (i.e., the fourth direction F4) (not shown in the figure). In this way, when the carrier body A200 rotates relative to the second positioning assembly A110 to the second direction F2 or the fourth direction F4, the distance between the front end of the carrier body A200 and the left or right door can be shortened, thereby making it easier for the user to carry the child out of the carrier body A200 or put the child into the carrier body A200.

[0285] When the carrier body A200 is in the second usage state relative to the positioning component A100, the two engaging parts A210 (i.e. the first engaging part A2101 and the second engaging part A2102) are respectively locked to the rear two groups of engaging hooks A151 (i.e. the second group of engaging hooks A1512 and the third group of engaging hooks A1513) arranged near the rear end of the first positioning component A110. For example, when the first positioning component A110 is rotated relative to the second positioning component A120 to face the second direction F2 (see Figure 49), and the front end of the carrier body A200 faces the second direction F2 (see Figure 50), 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 (see Figures 49 and 51). At this time, the front end of the carrier body A200 retracts inward relative to the first positioning component A110 along the direction of the carrier body A200 (i.e., the second direction F2) (see Figures 50 and 51). For another example, when the first positioning component A110 is rotated relative to the second positioning component A120 to face the fourth direction F4 (not shown), and the carrier 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 carrier body A200 retracts inward relative to the first positioning component A110 along the direction of the carrier body A200 (i.e., the fourth direction F4). For another example, when the first positioning assembly A110 rotates relative to the second positioning assembly A120 to face the third direction F3, and the carrier body A200 faces the third direction F3, the first engaging member A2101 is locked to the second set of engaging hooks A1512, and the second engaging member A2102 is locked to the third set of engaging hooks A1513. At this time, the front end of the carrier body A200 retracts inward relative to the first positioning assembly A110 along the direction of the carrier body A200 (i.e., the third direction F3) (see Figures 52 and 53). In this way, when the carrier body A200 rotates relative to the second positioning assembly A110 to the second direction F2 (see Figures 50 and 51) or the fourth direction F4, the distance between the front end of the carrier body A200 and the left or right door can be increased to prevent the child from hitting the left or right door. In addition, when the child sits sideways, there is more space for the child's feet. Similarly, when the carrier body A200 rotates to the third direction F3 relative to the second positioning assembly A120 along with the first positioning assembly A110 (see Figure 52), the distance between the front end of the carrier body A200 and the backrest of the car seat can be increased, so that the child has more space for placing his feet when sitting rear-facing.

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

[0287] Optionally, in another embodiment, the carrier body A200 may have three engaging parts A210, and the first connecting mechanism A150 may include three groups of engaging hooks A151 as an example to briefly explain the principle that two engaging parts A210 can be selectively locked to any two adjacent groups of engaging hooks A151 so that the carrier body A200 has a first usage state and a second usage state relative to the positioning component A100.

[0288] In order to facilitate understanding of the engaging relationship between the three engaging parts A210 and the three sets of engaging hooks A151, refer to Figures 53 and 54. Among the three engaging parts A210, the engaging part A210 close to the front end of the carrier body A200 is defined as the first engaging part A2101, the engaging part A210 close to the rear end of the carrier body A200 is the second engaging part A2102, and the engaging part A210 located between the two engaging parts A210 is the third engaging part A2103. Similarly, with the first positioning assembly A110 rotated relative to the second positioning assembly A120 to face the first direction F1 as a reference, the three sets of engaging hooks A151 on the first positioning assembly A110 along the Q3 direction are 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. In other words, when the first positioning assembly A110 faces the first direction F1, the first set of engaging hooks A1511 is located at the front end along the first direction F1 (or Q1 direction), i.e., closer to the support leg A162, while the third set of engaging hooks A1513 is located at the rear end along the first direction F1 (or Q1 direction). In this embodiment, the carrier body A200 engages with the first positioning assembly A110 in the same direction. It should be noted that when the carrier body A200 and the first positioning assembly A110 are engaged in the same direction, the first group of engaging hooks A1511 can be considered as closer to the front end of the carrier body A200, and the third group of engaging hooks A1513 can be considered as closer to the rear end of the carrier body A200.

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

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

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

[0292] Please refer to Figures 55 to 57, which schematically illustrate perspective views of a carrier B1000 provided according to a fourth aspect of the present invention. The carrier B1000 includes a carrier body B300 and a positioning assembly B100 provided according to another embodiment of the present invention. The following description of the carrier B1000 will also include an explanation of the carrier body B300 and the positioning assembly B100.

[0293] Figures 58 to 60 schematically illustrate the structure of a positioning assembly B100 in an embodiment of the fourth aspect of the present invention. This positioning assembly B100 is used to mount a vehicle body B300 (see Figures 55 to 57) to a car seat (not shown). In one embodiment, the positioning assembly B100 may include a first positioning assembly B110 and a second positioning assembly B120. Figures 61 and 62 illustrate the structure of the second positioning assembly B120 in the positioning assembly B100 in one embodiment of the present invention, while Figure 63 illustrates the structure of the first positioning assembly B110 in the positioning assembly B100 in one embodiment of the present invention. One of the first positioning assembly B110 and the second positioning assembly B120 is provided with a first track B131 and a second track B132 arranged in a cross-connection manner. The other of the first positioning assembly B110 and the second positioning assembly B120 is provided with a sliding assembly that slides along the first track B131 and the second track B132. Specifically, the sliding assembly includes a first slider B141 and a second slider B142. For example, as shown in Figures 61 to 63, the first positioning assembly B110 is provided with a first sliding member B141 and a second sliding member B142, and the second positioning assembly B120 is provided with a first track B131 and a second track B132. Alternatively, in other embodiments not shown, the first positioning assembly B110 is provided with a first track B131 and a second track B132, and the second positioning assembly B120 is provided with a first sliding member B141 and a second sliding member B142. The first sliding member B141 slides along one of the first track B131 or the second track B132, and the second sliding member B142 slides along the other of the first track B131 or the second track B132. For example, as shown in Figures 62 and 63, the first sliding member B141 slides along the second track B132, and the second sliding member B142 slides along the first track B131. Alternatively, in other embodiments not shown, the first sliding member B141 slides along the first track B131, and the second sliding member B142 slides along the second track B132. In this way, by sliding the first sliding member B141 along one of the first track B131 or the second track B132, and sliding the second sliding member B142 along the other of the first track B131 or the second track B132, the first positioning assembly B110 can be simultaneously displaced relative to the rotation of the second positioning assembly B120.

[0294] In one embodiment, as shown in Figures 55 and 58, a first positioning assembly B110 is used to connect to the vehicle body B300, and a second positioning assembly B120 is used to connect to the car seat. Specifically, as shown in Figures 57 to 59, the first positioning assembly B110 is provided with a first connecting mechanism B170 (e.g., a snap hook), which is primarily used to connect to a snap member (not shown) at the bottom of the vehicle body B300. The second positioning assembly 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 primarily used to secure the second positioning assembly B120 to the car seat, and the support leg B190 is primarily used to abut against the floor inside the vehicle. In this way, when the positioning assembly B100 is installed on the car seat and the vehicle body B300 is installed on the positioning assembly B100, the orientation of the vehicle body B300 can be changed by rotating the first positioning assembly B110, allowing the vehicle body B300 to have different usage modes. In some embodiments, the orientation of the carrier body B300 depends on the extension direction of the first rail B131 and the second rail B132. For example, when the first rail B131 extends along the first direction F1 or the third direction F3, and the second rail B132 extends along the second direction F2 or the fourth direction F4, the carrier body B300 has a usage mode facing the first direction F1 or the third direction F3, and a usage mode facing the second direction F2 or the fourth direction F4.

[0295] 61 and 62 , in one embodiment, the intersection of the first track B131 and the second track B132 is defined as the intersection center B133. The first track B131 and the second track B132 are each divided into two track segments by the intersection center B133. For example, the first track B131 is divided by the intersection center B133 into a first track segment B1311 and a second track segment B1312. The second track B132 is divided by the intersection center B133 into a third track segment B1321 and a fourth track segment B1322. 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. The third direction F3 is parallel to but opposite to the first direction F1, and the fourth direction F4 is parallel to but opposite to the second direction F2. Both the first direction F1 and the third direction F3 intersect with 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 assembly B100 is secured to the vehicle seat, the first direction F1 is the front of the vehicle during normal travel, i.e., the direction of the front of the vehicle. The second direction F2 is the left side of the vehicle during normal travel, i.e., the direction of the left door of the vehicle. The third direction F3 is the rear of the vehicle during normal travel, i.e., the direction of the rear of the vehicle. The fourth direction F4 can be considered the right side of the vehicle during normal travel, i.e., the direction of the right door of the vehicle. This allows the vehicle body B300 to rotate relative to the second positioning assembly B120 to face the front, rear, left, or right of the vehicle, enabling the vehicle body B300 to have forward, rear, and sideways modes.

[0296] In this embodiment, the first positioning assembly 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 assembly B110, taking the carrier body B300 installed on the first positioning assembly B110 as an example, the front-to-back direction of the carrier body B300 is parallel to the front-to-back direction of the first positioning assembly B110, and the left-to-right direction of the carrier body B300 is parallel to the left-to-right direction of the first positioning assembly B110. Specifically, when an infant or child is riding in the carrier body B300, the front end of the first positioning assembly B110 is closer to the infant's or child's feet than the rear end. Conversely, the rear end of the first positioning assembly B110 is closer to the infant's or child's head than the front end. The left end of the first positioning assembly B110 is closer to the infant's or child's left hand than the right end. The right end of the first positioning assembly B110 is closer to the infant's or child's right hand than the left end. When the first positioning component A110 is facing in a certain direction, it means that the carrier body A200 is also facing in the same direction; at the same time, the children riding in the carrier body A200 are also facing in the same direction. In order to intuitively understand the front and rear directions and the left and right directions of the carrier body B300 and the first positioning component B110, the "front" and "rear" directions are schematically indicated by arrows Q1 and Q3 in the accompanying drawings, and the "left" and "right" directions are schematically indicated by arrows Q2 and Q4, respectively. Among them, the Q1 direction is parallel and opposite to the Q3 direction, the Q2 direction is parallel and opposite to the Q4 direction, and the Q1 direction is staggered with the Q2 direction. Specifically, the Q1 direction is perpendicular to the Q2 direction. These directional terms are only used to make the description of the embodiments of the present invention clearer, and are not used to improperly limit the scope of protection of the present invention. Therefore, the aforementioned “the carrier body B300 can rotate relative to the second positioning component B120 to face the front, rear, left or right side of the car along with the first positioning component B110” means that the front end of the carrier body B300 and the first positioning component B110 can face the front, rear, left or right side of the car.

[0297] Referring to Figures 61 to 63, in 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, where 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, where 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 other embodiments not shown, the lengths of some of the track segments may be equal, while the lengths of the remaining track segments may be unequal. Alternatively, the lengths of all track segments may be unequal.

[0298] Please continue to refer to Figures 61 to 63. In this embodiment, taking the example in which the second positioning component B120 is provided with a cross-arranged first track B131 and a second track B132, the first positioning component B110 is provided with a first sliding member B141 and a second sliding member B142 at intervals, and the first sliding member B141 slides along the second track B132, and the second sliding member B142 slides along the first track B131, the structures and positions of the first track B131, the second track B132, the first sliding member B141 and the second sliding member B142 are briefly described, and the principle of the first positioning component B110 rotating and moving relative to the second positioning component B120 is briefly described.

[0299] In one embodiment, the first positioning assembly B110 is generally disc-shaped, the first sliding member B141 is disposed at the center of the first positioning assembly B110, and the second sliding member B142 is disposed offset from the center. Of course, in other embodiments, the first positioning assembly B110 may be other symmetrical shapes (e.g., elliptical, rectangular, etc.), and the first sliding member B141 may be disposed at the geometric center of the first positioning assembly B110 or at a position offset from the geometric center; alternatively, the first positioning assembly B110 may be asymmetrical in shape, and the location of the first sliding member B141 may be determined based on the shape of the first positioning assembly B110.

[0300] Referring to Figures 55, 62, and 63, in some embodiments, when the carrier body B300 on the first positioning assembly B110 is oriented in the first direction F1, the second slider B142 is positioned on the first positioning assembly B110 behind the first slider B141 along the first direction F1. Specifically, during the process of the first positioning assembly B110 turning and moving relative to the second positioning assembly 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 assembly B110 is oriented in the first direction F1 relative to the second positioning assembly B120. At this time, the carrier body B300 mounted on the first positioning assembly 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 assembly B110 is oriented in the third direction F3 (i.e., away from the first direction F1) relative to the second positioning assembly B120. At this time, the carrier body B300 installed on the first positioning assembly B110 can be considered to be facing 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 assembly B110 is oriented in the second direction F2 relative to the second positioning assembly B120. At this time, the carrier body B300 installed on the first positioning assembly B110 can be considered to be facing 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 assembly B110 is oriented in the fourth direction F4 relative to the second positioning assembly B120. At this time, the carrier body B300 installed on the first positioning assembly B110 can be considered to be oriented in the right direction 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 in the second track B132 and the position of the second slider B142 in the first track B131, the orientation of the carrier body B300 on the first positioning assembly B110 can be changed, so that the carrier body B300 has a forward mode, a backward mode, and a sideways mode. In other words, "forward mode" refers to the state where the front end of the first positioning component B110 or the front end of the carrier body B300 is facing the front of the car, "backward mode" refers to the state where the front end of the first positioning component B110 or the front end of the carrier body B300 is facing the rear of the car, and "side mode" refers to the state where the front end of the first positioning component B110 or the front end of the carrier body B300 is facing the side of the car (i.e., the door).

[0301] 55 , 56 , and 60 to 63 , the principle and process of the rotation and displacement of the first positioning assembly B110 relative to the second positioning assembly B120 will be briefly described below.

[0302] Similarly, for the convenience of 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 set in the first direction F1 relative to the second positioning component B120, the first sliding member B141 is located at the intersection center B133, that is, 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, that is, point N.

[0304] When the user needs to switch the first positioning component B110 relative to the second positioning component B120 from being set in the first direction F1 to being set in the second direction F2, it is equivalent to changing the first positioning component B110 relative to the second positioning component B120 from being set in the front to being set in the left. The user can pull the first positioning component B110 or the carrier body B300 to the left, and at the same time, make the first positioning component B110 tend to rotate counterclockwise. In this way, the first sliding member B141 can be moved from point M to point M' in the second track B132, and at the same time, the second sliding member B142 can be synchronously moved from point N to point N' in 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 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., the intersection center B133. At this time, the first positioning component B110 is oriented in the second direction F2 relative to the second positioning component B120. It should be noted that the switching process between the first direction F1 and the second direction F2 of the first positioning component B110 relative to the second positioning component B120 is reversible, that is, the orientation of the first positioning component B110 relative to the second positioning component B120 can switch from the first direction F1 to the second direction F2, and can also switch from the second direction F2 to the first direction F1.

[0305] When the user needs to switch the first positioning component B110 relative to the second positioning component B120 from being oriented in the first direction F1 to being oriented in the fourth direction F4. The user can pull the first positioning component B110 or the carrier body B300 to the right, and at the same time, make the first positioning component B110 tend to rotate clockwise, so that the first sliding member B141 can move from point M to point M" in the second track B132, and at the same time, make the second sliding member B142 synchronously move from point N to point N' in 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 move laterally (specifically along the right direction) relative to the second positioning component B120. When the first sliding member B141 moves to point M", the second sliding member B142 is located at point N', that is, the intersection center B133. At this time, the first positioning component B110 is facing the fourth direction F4 relative to the second positioning component B120. Likewise, the switching process of the first positioning element B110 relative to the second positioning element B120 between the first direction F1 and the fourth direction F4 is reversible.

[0306] In addition, the user can also switch the first positioning component B110 from being oriented in the second direction F2 or the fourth direction F4 to being oriented in the third direction F3 relative to the second positioning component B120. The following description will take the switching of the first positioning component B110 from being oriented in the second direction F2 to being oriented in the third direction F3 relative to the second positioning component B120 as an example. Specifically, the user can pull the first positioning component B110 or the carrier body B300, and at the same time, the first positioning component B110 has a tendency to rotate counterclockwise, so that the second sliding component B142 can move from point N' to point N" in the first track B131, and at the same time, the first sliding component B141 can synchronously move from point M' to point M in the second track B132. During this process, the first positioning component B110 gradually begins to rotate relative to the second positioning component B120, and at the same time, the rear end of the first positioning component B110 can move relative to the second positioning component B120 in the first direction F1. When the second sliding component B142 moves to point N", the first sliding component B141 is located at point M, that is, the intersection center B133. At this time, 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 between 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 being set in the third direction F3 to being set in the fourth direction F4, the user directly pulls the first positioning component B110 or the carrier body B300, and makes the first positioning component B110 tend to rotate counterclockwise. In this way, the first sliding component B141 can move from point M to point M” in the second track B132, and the second sliding component B142 can synchronously move from point N” to point N' in 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 set in the fourth direction F4 to being set in the first direction F1, the user directly pulls the first positioning component B110 or the carrier body B300, and makes the first positioning component B110 tend to rotate counterclockwise. In this way, the second sliding component B142 can move from point N' to point N in the first track B131, and the first sliding component B141 can synchronously move from point M" to point M in the second track B132.

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

[0309] Referring to Figures 61 to 64, in one embodiment, the second positioning assembly B120 includes a second housing, which has 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 are connected up and down and enclose 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, as shown in Figures 63 and 64 , the first track B131 may include a first channel B1313 and a first chute B1314, and the second track B132 may include a second channel B1323 and a second chute B1324. The first channel B1313 and the second channel B1323 are both located on the lower surface of the second top cover B122, i.e., on a side facing the second mounting cavity B121. The first channel B1313 and the second channel B1323 are interconnected, and both are connected to the second mounting cavity B121. The first chute B1314 is located inside the first channel B1313, and the second chute B1324 is located inside the second channel B1323. Both the first chute B1314 and the second chute B1324 are through-channel structures. Specifically, when the first sliding member B141 slides along the second track B132, it can be regarded as the first sliding rod B1411 sliding in the second sliding groove B1324, and at the same time the first slider B1412 slides in the second channel B1323; when the second sliding member B142 slides along the first track B131, it can be regarded as the second sliding rod B1412 sliding in the first sliding groove B1314, and at the same time the second slider B1413 slides in the first channel B1313. More specifically, as shown in FIG64 , 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 chute 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 chute B1314. This prevents the first slider B141 from sliding off the second track B132 and the second slider B142 from sliding off the first track B131, thereby preventing the first positioning assembly B110 from detaching from the second positioning assembly B120 during rotation and displacement relative to the second positioning assembly B120. Furthermore, the length of the first slider B1412 along the extension direction of the second track 132 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 can be restricted from sliding within the second track B132, and the second slider B142 can be restricted from sliding within the first track B131, thus 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, and 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, the first sliding member B141 and the second sliding member B142 are both integrally formed structures, that is, the first sliding member B1412 is integrally formed with the first sliding rod B1411, and the two are integrally formed, and the second sliding member B1422 is integrally formed with the second sliding rod B1412, and the two are integrally formed. Of course, in other embodiments, the first sliding member B1412 and the first sliding rod B1411 are different components, and the first sliding member B141 can be formed by connecting the first sliding member B1412 and the first sliding rod B1411 through welding, riveting, etc.; the second sliding member B1422 and the second sliding rod B1421 are also different components, and the second sliding member B142 can be formed by connecting the second sliding member B1422 and the second sliding rod B1412 through welding, riveting, etc.

[0310] It should be noted that the above-mentioned “through groove structure” refers to the groove body connected to the second installation cavity B121, and the “groove structure” refers to the groove body not connected to the second installation cavity B121.

[0311] Referring to Figures 55 to 57, the carrier body B300 can be, for example, a seat, a basket or a sleeping box. As can be seen from the foregoing, when the carrier B1000 is installed in a car, the carrier body B300 can be rotated to any one of the first direction F1, the second direction F2, the third direction F3 or the fourth direction F4 under the action of the first positioning component B110, so that the carrier body B300 has four modes, namely forward mode, left mode, backward mode and right mode. Specifically, when a child needs to be placed in the carrier body B300 or taken out of the carrier body B300, the carrier body B300 can be placed in the left mode or the right mode, so as to facilitate the holding. When the car needs to be driven, the carrier body B300 can be placed in the forward mode or the backward mode, which improves the safety of the child's travel. Specifically, to further consider the safety of children traveling, especially for children who are younger (e.g., less than 15 months old), shorter in height, or lighter in weight, the vehicle body B300 should not be in forward mode, that is, the vehicle body B300 should not be facing the front of the car (i.e., the first direction F1). However, in actual use, the user may misadjust the orientation of the first positioning component B110 relative to the second positioning component B120, thereby misusing the forward mode or backward mode of the vehicle body B300, posing a safety hazard to children.

[0312] In order to avoid the problem of users misusing the various usage modes of the carrier body B300, the positioning assembly B100 in an embodiment of the fourth aspect of the present invention may further include an anti-misuse mechanism B150. The anti-misuse mechanism B150 can be movably arranged on the first positioning assembly B110 or the second positioning assembly B120, and is used to selectively allow or limit the movement of the sliding assembly (the first sliding member B141 or the second sliding member B142), thereby selectively limiting the angle of rotation of the first positioning assembly B110 relative to the second positioning assembly B120. For example, the anti-misuse mechanism B150 can limit the movement of the first sliding member B141, thereby limiting the first positioning assembly B110 from rotating to the second direction F2 or the fourth direction F4 relative to the second positioning assembly B120. Alternatively, the anti-misuse mechanism B150 can limit the movement of the second sliding member B142, thereby limiting the first positioning assembly B110 from rotating to the first direction F1 or the third direction F3 relative to the second positioning assembly B120.

[0313] Referring to Figures 65 to 67, in one embodiment, the anti-misuse mechanism B150 includes a blocking member B151. The blocking member B151 is movably disposed on the first positioning assembly B110 or the second positioning assembly B120 so as to be able to extend into or out of the first track B131 or the second track B132, thereby selectively allowing or restricting the movement of the first sliding member B141 or the second sliding member B142. Specifically, the blocking member B151 is movably disposed so as to have a first position and a second position. In this embodiment, the specific structure and operating principle of the anti-misuse mechanism B150 are explained by taking the example of the anti-misuse mechanism B150 being movably disposed on the second positioning assembly B120 and being used to restrict the movement of the second sliding member B142.

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

[0315] Referring to Figures 62, 63, 65, and 66, in one embodiment, the blocking member B151 is movably disposed along the movement path of the second sliding member B142 within the second track segment B1312. This is equivalent to the blocking member B151 being movably disposed within the region 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 toward the second track segment B1312 and the blocking member B151 is in the first position, the blocking member B151 at least partially extends 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 assembly B110 from rotating relative to the second positioning assembly 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 block the second sliding member B142 from moving in the direction away from the intersection center B133 within the second track segment B1312, thereby limiting the first positioning component B110 from rotating to the first direction F1, and thus the carrier body B300 cannot be used in the first direction F1. In this way, the user can be reminded to avoid misusing the forward mode of the carrier body B300.

[0316] Please refer to 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 and is used to provide an elastic restoring force for the blocking member B151 to drive the blocking member B151 to remain constantly in the first position. In this embodiment, the blocking member B151 is disposed at one end of the second rail segment B1312 away from the intersection center B133. Specifically, referring to Figures 62, 63, 65 and 66, when the first positioning assembly B110 is oriented in the first direction F1 relative to the second positioning assembly B120, the first sliding member B141 is located at the intersection center B133, and the second sliding member B142 is located at one end of the second rail segment B1312 away from the intersection center B133. At this time, the blocking member B151 is located directly below the second sliding member B142. More specifically, the blocking member B151 is located directly below the second slider B1422. The blocking member B151 is pressed against the second slider B1422 and held in the second position (see FIG65 ). At this point, the first positioning assembly B110 can freely switch from the first direction F1 to another direction (e.g., the second direction F2) relative to the second positioning assembly B120. More specifically, when the first positioning assembly B110 switches from the first direction F1 to another direction relative to the second positioning assembly B120, the second slider B1422 moves with the second sliding rod B1421, becoming 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 restoring force of the first restoring member B153, extending into the second rail segment B1322, thereby preventing the second slider B1422 from moving to the end of the second rail segment B1322 away from the intersection center B133, thereby limiting the first positioning assembly B110 from rotating from other directions to the first direction F1. It can be seen that the above-mentioned blocking member B151 can allow the first positioning assembly B110 to switch from the first direction F1 to other directions, while limiting the first positioning assembly B110 from switching from other directions to the first direction F1.

[0317] In some other embodiments, when the first positioning assembly B110 rotates relative to the second positioning assembly B120 toward the first direction F1, the first slider B141 is located at the intersection center B133, the second slider B142 is located at the end of the second track segment B1312 away from the intersection center B133, and the blocking member B151 can be offset from the second slider B1422. Specifically, the blocking member B151 is located in front of the second slider B1422 along the first direction F1. At this time, the blocking member B151 does not abut against the second slider B1422. The blocking member B151 remains in the first position under the reset force of the first reset member B153. In this way, the blocking member B151 blocks the second slider B142 from moving in the second track segment B1312 toward the intersection center B133, thereby limiting the rotation of the first positioning assembly B110 relative to the second positioning assembly B120, and thus preventing the first positioning assembly B110 from directly switching to the second direction F2 or the fourth direction F4.

[0318] Of course, in some other embodiments, a guide ramp (not shown) is provided on the side of the blocking member B151 facing away from the intersection center B133. Thus, when the first positioning assembly B110 is oriented in the first direction F1, even if the blocking member B151 is in the first position, the second slider B1422, under the action of the guide ramp, can push the blocking member B151 as it slides toward the intersection center B133, causing the blocking member B151 to exit the second track segment B1312, ultimately allowing the first positioning assembly B110 to rotate relative to the second positioning assembly B120 from the first direction F1 to the second direction F2 or the fourth direction F4. The guide ramp provided on the side of the blocking member B151 facing away from the intersection center B133 allows the first positioning assembly B110 to switch from the first direction F1 to other directions while also restricting the first positioning assembly B110 from switching from other directions (such as the second direction F2 or the fourth direction F4) to the first direction F1, thereby preventing the forward mode of the carrier body B300 from being misused. Of course, in other embodiments, when the first positioning assembly B110 is oriented in the first direction F1 relative to the second positioning assembly B120, a guiding slope may be provided on the side of the second slider B1422 close to the intersection center B133 to achieve the above-mentioned effect.

[0319] Referring to Figures 66 to 69, in one embodiment, the anti-misuse mechanism B150 further includes a release assembly B152. This release assembly B152 is disposed on the first positioning assembly B110 or the second positioning assembly B120 and is drivingly connected to the blocking member B151, driving the blocking member B151 out of the first track B131 or the second track B132, thereby allowing movement of the first slider B141 or the second slider B142. Specifically, in this embodiment, the release assembly B152 is disposed on the second positioning assembly B120 and is drivingly connected to the blocking member B151, driving the blocking member B151 from the first position to the second position. This allows the first positioning assembly B110 to freely switch between various positions relative to the second positioning assembly B120.

[0320] Continuing with Figures 66 to 69, in one embodiment, the release assembly B152 may include an operating member B1521 and a pulling member B1522. The operating member B1521 is movably disposed on the second positioning assembly B120 and has a locked position and a released position. The pulling member B1522 is connected between the operating member B1521 and the blocking member B151. Specifically, as shown in Figure 68, the second top cover B122 is provided with a through-hole B1222. The operating member B1521 is movably disposed within the second mounting cavity B121. The operating portion of the operating member B1521 extends through the through-hole B1222 into the second mounting cavity B121 and protrudes from the surface of the second top cover B122, thereby facilitating user operation. As shown in Figures 67, 69, and 70, the pulling member B1522 is, for example, a traction rope, 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 released position, the operating member B1521 drives the blocking member B151 to exit the first track B131 through the traction member B1522, which is equivalent to driving the blocking member B151 to switch from the first position to the second position (from Figure 66 to Figure 65).

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

[0322] Referring to Figures 65 to 67 and Figure 70, in one embodiment, the anti-misuse mechanism B150 further includes a fixing seat B154. The fixing seat 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 disposed opposite each other and face the first track B131. A first return member B153 is disposed within the cavity B1541 and abuts against the blocking member B151. Specifically, the blocking member B151 is movably disposed within the cavity B1541. The first return member B153 is disposed within the cavity B1541 and abuts between the blocking member B151 and the fixing seat B154. The traction member B1522 passes through the operating hole B1543 and connects 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 shown in Figures 67 and 70, the side wall of the fixed seat B154 is provided with a strip-shaped guide groove B1544, and the extension direction of the guide groove B1544 is the same as the movement direction of the blocking member B151. The blocking member B151 is penetrated by a connecting shaft B156, which extends into the guide groove B1544 and slidably cooperates with the guide groove B1544, allowing the blocking member B151 to slide along the guide groove B1544 of the fixed seat B154 to extend into or exit the first track B131, thereby restricting or allowing the first positioning assembly B110 to face the first direction F1.

[0323] Referring to Figures 65 and 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 a portion of the blocking member B151 is located on the moving path of the second slider B1422 to prevent the first positioning assembly B110 from rotating toward the first direction F1.

[0324] To ensure that the blocking member B151 remains stably in the second position, in one embodiment, as shown in Figures 67 to 69, the anti-misuse mechanism B150 further includes a state locking assembly B155. This state locking assembly B155 is disposed on the second positioning assembly B120 and is used to lock the operating member B1521 in a locked position or a released position. By locking the operating member B1521 in the released position, the pulling member B1522 remains in a taut state, ultimately maintaining the blocking member B151 in the second position.

[0325] Referring to Figures 68 to 72, in one embodiment, the state locking assembly B155 may include a locking member B1551. The locking member B1551 is movably disposed on the second positioning assembly B120, specifically, movably disposed within the second mounting cavity B121, and has a third position and a fourth position. Specifically, the operating member B1521 is provided with a limiting portion B15211. When the locking member B1551 is in the third position, the locking member B1551 abuts against the limiting portion B15211, thereby restricting the operating member B1521 from switching between the unlocked position and the locked position. This means that the locking member B1551 can lock the operating member B1521 in either the unlocked position or the locked position, thereby maintaining the blocking member B151 in either the second position or the first position. When the locking member B1551 is in the fourth position, the locking member B1551 is separated 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 movement direction of the operating member B1521 intersects the movement direction of the locking member B1551. Specifically, in this embodiment, the wall surface where the locking member B1551 contacts the limiting portion B15211 is an arc-shaped structure, and the wall surface where the limiting portion B15211 contacts 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 process.

[0326] Specifically, in this embodiment, as shown in Figures 68 to 72, the state locking assembly B155 may further include a second restoring member B1552, which abuts between the second positioning assembly B120 and the locking member B1551 and is used to provide an elastic restoring force for the locking member B1551 to drive the locking member B1551 to remain 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 part B1521 can overcome the elastic force of the second reset part B1552 to push the locking part B1551 so that the locking part B1551 switches from the third position to the fourth position. In addition, during the pushing process, since the wall surface where the locking part B1551 contacts the limiting part B15211 is an arc-shaped structure, and the wall surface where the limiting part B15211 contacts the locking part 1551 is also an arc-shaped structure, the limiting part B15211 can overcome the obstruction of the locking part B1551, so that the operating part B1521 can switch to the unlocking position. When the limiting portion B15211 passes over the locking member B1551, the locking member B1551 automatically switches from the fourth position to the third position under the elastic reset force of the second reset member B1552, that is, the locking member B1551 switches from one side of the limiting portion B15211 to the other side of the limiting portion B15211, so that it can once again abut against the operating member B1521 (that is, the other side of the limiting portion B1521), 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 once again operate the operating member B1521 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 the locking member B1551, so that the locking member B1551 switches from the third position to the fourth position again. Similarly, because the wall surface where the locking member B1551 contacts the limiting portion B15211 and the wall surface where the limiting portion B15211 contacts the locking member B1551 are both arc-shaped structures, the limiting portion B15211 can overcome the obstruction of the locking member B1551, allowing the operating member B1521 to switch to the locked position. After the limiting portion B15211 overcomes 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 restoring member B1552, so that it can once again contact the operating member B1521, locking the operating member B1521 in the locked position.

[0327] The following briefly describes the working principle and process of the anti-misuse mechanism B150 for blocking the movement of the second sliding member B142 with reference to the diagram.

[0328] Referring to Figures 65 to 69 , when the operating member B1521 is in the unlocked position, the pulling member B1522 is tightened, thereby pulling the blocking member B151 away from the second track segment B1312 of the first track B131. The second restoring member B1552 acts to maintain the locking member B1551 in the third position. This allows the locking member B1551 to abut against the stopper B15211 of the operating member B1521, maintaining the operating member B1521 in the unlocked position. In this manner, the carrier body B300 can rotate relative to the second positioning assembly B120 along with the first positioning assembly B110 to face the first direction F1 (see Figures 55 and 63 ).

[0329] When it is necessary to prevent the user from mistakenly switching the first positioning component B110 from any of the second direction F2, the third direction F3 or the fourth direction F4 to the first direction F1, as shown in Figures 67 to 69, the operating member B1521 can be operated (such as pushed) to switch the operating member B1521 from the unlocked position to the locked position (from Figure 59 to Figure 58). In the process of switching from the unlocked position to the locked position, the operating member B1521 will push 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 is reset to the third position and abuts against the limiting portion B15211 of the operating member B1521, so that the operating member B1521 can be maintained in the locked position. When the operating member B1521 gradually switches from the unlocking position to the locking position, the traction member B1522 gradually becomes loose, as shown in Figures 65 and 66. Under the action of the first restoring 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 section 1312 of the first track 131 to block the second sliding member B142 from moving in the direction away from the intersection center B133, thereby limiting the first positioning component B110 from rotating relative to the second positioning component B120 to the first direction F1, so that the carrier body 300 cannot switch to the forward mode (see Figures 55 and 56).

[0330] Similarly, when the user needs to use the forward mode of the carrier body B300, as shown in Figures 67 to 69, the operating member B1521 can be operated (e.g., pushed) to switch the operating member B1521 from the locked position to the unlocked position (from Figure 58 to Figure 59). During the process of switching from the locked position to the unlocked position, the operating member B1521 will push 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 portion B15211 of the operating member B1521, so that the operating member B1521 can be maintained in the unlocked position. When the operating member B1521 gradually switches from the locked position to the unlocked position, the traction member B1522 is gradually tightened and pulls the blocking member B151 out of the second track segment B1312 of the first track B131, that is, switches from the first position to the second position (see Figures 66 and 65). In this way, the first positioning component B110 rotates relative to the second positioning component B120 to face the first direction F1, so that the carrier body B300 can switch to the forward mode (see Figures 55 and 56).

[0331] As described above, when the anti-misuse mechanism B150 is provided on the moving path of the second sliding member B142 on the first track B131, it can block the movement of the second sliding member B142, thereby limiting the first positioning assembly B110 from rotating relative to the second positioning assembly B120 to the extension direction toward the first track B131. Of course, in other embodiments, the anti-misuse mechanism B150 can also be provided on the moving path of the first sliding member B141 on the second track B132, so that the movement of the first sliding member B141 can be blocked, thereby limiting the first positioning assembly B110 from rotating relative to the second positioning assembly B120 to the extension direction toward the second track B132. Specifically, the working principle of the anti-misuse mechanism B150 for blocking the movement of the first sli...
