[0002] A car child safety seat, also known as a Child Restraint System (CRS), is a seat specifically designed for children and installed inside a car to effectively improve their safety while traveling. This seat generally consists of a base and a carrier body mounted on the base. The carrier body can rotate relative to the base to face different directions. However, from a safety perspective, too many adjustable angles of the carrier body may lead to user misoperation, causing safety hazards.

Detailed Implementation

[0131] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0132] Figure 1 shows a perspective view of a vehicle A1000 provided according to an embodiment of the first aspect of the present invention. The vehicle A1000 may include a vehicle body A200 and a positioning component A100 provided according to some embodiments of the first aspect of the present invention. The vehicle body A200 is connected to the positioning component A100, which is used to connect to a car seat (not shown in the figure). In other words, the vehicle body A200 can be mounted to a car seat via the positioning component A100, thereby improving the safety of children or infants riding in a car. The vehicle body A200 and the positioning component A100 will be described below concurrently with the description of the vehicle A1000.

[0133] Referring to Figures 2 to 4, in a first embodiment of the first aspect, the positioning component A100 may include a first positioning component A110 and a second positioning component A120. The first positioning component A110 is used to connect to the vehicle body A200, and the second positioning component A120 is used to connect to the vehicle seat. One of the first positioning component A110 and the second positioning component A120 is provided with a first track A121 and a second track A122, and the other of the first positioning component A110 and the second positioning component A120 is provided with a first slider A111 and a second slider A112. Specifically, the first track A121 and the second track A122 are intersected to form a T-shape. The first slider A111 slides along the first track A121, and the second slider A112 slides along the second track A122. In this way, the first positioning component A110 can rotate and displace relative to the second positioning component A120 simultaneously. Furthermore, due to the T-shaped structure, the first positioning component A110 can have both a rearward usage mode (see Figure 2) and a lateral usage mode (see Figures 8 and 9) on the second positioning component A120. It should be noted that the first track A121 and the second track A122 are connected, and the first slider A111 and the second slider A112 are spaced apart.

[0134] It should also be noted that when the positioning component A100 is installed on the car seat, with the car as the reference, "rearward use mode" refers to the state in which the first positioning component A110 faces the rear of the car. "Side use mode" refers to the state in which the first positioning component A110 faces the car door, which includes both the state in which it faces the left door or the right door.

[0135] Referring to Figures 1 and 2, in one embodiment, the second positioning component A120 is provided with an ISOFIX connector A124A and a support leg A124B. The ISOFIX connector A124A is located approximately at the rear end of the second positioning component A120, and the support leg A124B is located approximately at the front end of the second positioning component A120. Specifically, when the second positioning component A120 is mounted on a car seat, the ISOFIX connector A124A securely connects the second positioning component A120 to the car seat, and the support leg A124B rests against the vehicle's interior floor. Through the connection and support provided by the ISOFIX connector A124A and the support leg A124B, the second positioning component A120 can be stably installed inside the vehicle.

[0136] In one embodiment, the carrier body A200 can be, for example, a baby carrier (see Figure 1), a seat (not shown), or a sleeping box (not shown) for carrying infants; or it can be a pet carrier (not shown) for carrying animals. It should be noted that the carrier body A200, such as a baby carrier or seat, typically includes a seat portion A210 and a backrest portion A220 connected and angled together. The seat portion A210 primarily supports the buttocks and legs of the infant, and its bottom typically has a locking mechanism (not shown). This locking mechanism is mainly used to connect with the connecting seat A115 of the first positioning component A110 (see Figure 2, specific structure described below), thereby achieving a quick connection between the carrier body A200 and the positioning component A100. Specifically, in this embodiment, the carrier body A200 is a baby carrier, primarily used to carry infants weighing no more than 35 pounds or with a height no more than 87 cm.

[0137] In this embodiment, as shown in Figures 3 and 4, the first positioning component A110 is provided with a first sliding member A111 and a second sliding member A112, and the second positioning component A120 is provided with a first track A121 and a second track A122. The structure and working principle of the positioning component A100 are briefly described below.

[0138] In one embodiment, referring to Figures 4 to 6, the first positioning component A110 includes a rotating seat A113, which comprises an upper rotating seat housing A1131 and a lower rotating seat housing A1132. The upper rotating seat housing A1131 and the lower rotating seat housing A1132 are vertically enclosed to form a receiving cavity A1133. Specifically, in this embodiment, the rotating seat A113 has a rotation axis, a first sliding member A111 is disposed on the rotating seat A113 and coaxially disposed with respect to the rotation axis, and a second sliding member A112 is disposed offset from the rotation axis. More specifically, a reinforcing member A114 is provided in the accommodating cavity A1133 of the rotating seat A113. The first sliding member A111 and the second sliding member A112 are respectively fixedly installed on the reinforcing member A114 and pass through the lower housing A1132 of the rotating seat, so that the first sliding member A111 can slide along the first track A121 and the second sliding member A112 can slide along the second track A122.

[0139] It should be noted that in this embodiment, the rotating seat A113 is approximately circular, and the aforementioned rotation axis can be considered as the center of the circle of the rotating seat A113. Of course, in other embodiments, the rotating seat A113 can also be other symmetrical shapes (such as ellipse, rectangle, etc.), and the rotation axis can be the geometric center of the rotating seat A113 or a position off from the geometric center; or, the rotating seat A113 can also be asymmetrical, and the rotation axis can be set according to actual needs.

[0140] Referring to Figures 4 and 6, in one embodiment, the first positioning component A110 further includes a connecting seat A115 for connecting and supporting the vehicle body A200. Specifically, the connecting seat A115 may include a connecting portion A1151 and a supporting portion A1152 connected to each other. The supporting portion A1152 extends upward at an angle relative to the connecting portion A1151, and an open mounting space A1153 is formed between the supporting portion A1152 and the connecting portion A1151. This mounting space A1153 is used to accommodate the seat portion A210 of the vehicle body A200 (see Figure 1). Specifically, the connecting portion A1151 is provided with a slot A1161 and a hook A1162. The slot A1161 is used to accommodate the engaging component of the vehicle body A200, and the hook A1162 is pivotally connected to the slot A1161 to close the opening of the slot A1161. This allows the engaging component at the bottom of the vehicle body A200 to be limited within the slot A1161, ultimately achieving a detachable connection between the vehicle body A200 and the first positioning component A110. Regarding the first positioning component A110, the connecting portion A1151 is generally a long strip structure that extends approximately along the radial direction of the rotating base A113, and the support portion A1152 is located at one end of the connecting portion A1151. Specifically, in this embodiment, the position of the support portion A1152 on the rotating seat A113 is referred to as the rear end of the first positioning component A110. Then, the position of the end of the connecting portion A1151 away from the support portion A1152 on the rotating seat A113 can be considered as the front end of the first positioning component A110, and the front and rear ends of the first positioning component A110 are arranged approximately along the same straight line. The support portion A1152 can be used to guide the carrier body A200 to be installed on the connecting seat A115. After the carrier body A200 is connected to the connecting portion A1151, the support portion A1152 can also be used to support the backrest portion A220 of the carrier body A200 (see Figure 1). This improves the stability of the carrier body A200 installed on the first positioning component A110. To better understand the front and rear ends of the first positioning component A110, referring to Figures 1 and 2, taking the vehicle body A200 installed on the first positioning component A110 as an example, the front end of the first positioning component A110 refers to the end away from the backrest A220 of the vehicle body A200, and the rear end of the first positioning component A110 refers to the end closer to the backrest A220 of the vehicle body A200. When an infant or toddler is seated inside the vehicle body A200, the front end of the first positioning component A110 is closer to the infant or toddler's feet than the rear end, and the rear end of the first positioning component A110 is closer to the infant or toddler's head than the front end.

[0141] Specifically, in this embodiment, as shown in FIG4, the first slider A111 and the second slider A112 are located on the lower surface of the first positioning component A110, that is, on the side of the rotating seat A113 opposite to the connecting seat A115. The first slider A111 is approximately coaxially arranged with the rotation axis of the rotating seat A113 (i.e., the first slider A111 can be considered to be located at the rotation axis), and the second slider A112 is approximately located below the support portion A1152, which can be considered to be located at the rear end of the rotating seat A113 (or the first positioning component A110). Therefore, from an overall perspective, the first slider A111 can be considered to be located in the middle of the first positioning component A110, and the second slider A112 can be considered to be located at the rear end of the first positioning component A110 and behind the first slider A111.

[0142] Therefore, it should be emphasized that the aforementioned "state in which the first positioning component A110 faces the rear of the vehicle" refers to the state in which the front end of the first positioning component A110 faces the rear of the vehicle and the rear end of the first positioning component A110 faces the front of the vehicle. In this case, when the infant is seated inside the vehicle body A200 mounted on the first positioning component A110, the infant's face is facing the rear of the vehicle. Similarly, "state in which the first positioning component A110 faces the vehicle door" refers to the state in which the front end of the first positioning component A110 faces the vehicle door. In this case, when the infant is seated inside the vehicle body A200 mounted on the first positioning component A110, the infant's face is facing the vehicle door.

[0143] In one embodiment, the positioning component A100 further includes a locking mechanism A130 (see Figures 8 and 12; the specific structure is described below). The locking mechanism A130 is disposed on one of the first positioning component A110 and the second positioning component A120, and is mainly used to lock the first positioning component A110 in the rearward use mode with the other of the two positioning components, thereby locking the first positioning component A110 in the rearward use mode. In other words, when the locking mechanism A130 is disposed on the first positioning component A110 and the first positioning component A110 is in the rearward use mode, the locking mechanism A130 locks with the second positioning component A120 to restrict the rotation of the first positioning component A110 relative to the second positioning component A120. Alternatively, when the locking mechanism A130 is disposed on the second positioning component A120 and the first positioning component A110 is in the rearward use mode, the locking mechanism A130 locks with the first positioning component A110 to restrict the first positioning component A110 from rotating relative to the second positioning component A120.

[0144] In the aforementioned positioning component A100, since the first track A121 and the second track A122 intersect in a T-shape, when the first slider A111 slides along the first track A121 and the second slider A112 slides along the second track A122, the first positioning component A110 can only switch between a rearward use mode and a lateral use mode. This design simplifies the usage modes of the first positioning component A110; for example, it does not have a forward use mode. This effectively prevents user error from causing the first positioning component A110 to switch to the forward use mode, thus preventing the basket from being used in a forward-facing position and improving the safety and reliability of the vehicle body A200. At the same time, users can also select a suitable usage mode from the rearward and lateral use modes according to different needs, thereby improving the applicability of the positioning component A100. Furthermore, when the first positioning component A110 is in the rearward use mode, the first positioning component A110 and the second positioning component A120 can be locked together by the locking mechanism A130 to restrict the rotation of the first positioning component A110 relative to the second positioning component A120, so that the first positioning component A110 can be stably maintained in the rearward use mode, thereby further improving the safety and reliability of the positioning component A100.

[0145] Referring to Figure 3, in one embodiment, the first track A121 on the second positioning component A120 extends along either the first direction F1 or the third direction F3, and the second track A122 extends along the second direction F2. The first direction F1 and the third direction F3 are parallel and opposite, and the second direction F2 intersects the first direction F1; specifically, the second direction F2 is perpendicular to the first direction F1. Considering the installation of the positioning component A100 on the car seat, the first direction F1 can be considered the left side of the car (i.e., the direction towards the left side door), the second direction F2 can be considered the front side of the car (i.e., the direction towards the front of the car), and the third direction F3 can be considered the right side of the car (i.e., the direction towards the right side door).

[0146] In this embodiment, regarding the first positioning component A110, when the positioning component A100 is installed on the car seat, as shown in FIG2, if the first positioning component A110 is in the rear-facing use mode, the first positioning component A110 can be considered to be rotated relative to the second positioning component A120 to face away from the second direction F2. At this time, the first slider A111 is located at the intersection center A123, and the second slider A112 is located on one side of the first slider A111 along the second direction F2, that is, the second slider A112 can be considered to be located in front of the first slider A111 along the second direction F2, and the second slider A112 is located on the second track A122 (see FIG7). As shown in FIG8 and FIG9, if the first positioning component A110 is in the side-facing use mode, the first positioning component A110 can be considered to be rotated relative to the second positioning component A120 to face towards the first direction F1 or the third direction F3. At this time, the second slider A112 is located at the intersection center A123, and the first slider A111 is located on the first track A121 (see Figures 10 and 11).

[0147] Referring to Figure 3, in this embodiment, the intersection of the first track A121 and the second track A122 is referred to as the intersection center A123. This intersection center A123 can be considered as dividing the first track A121 into a connected first track segment A121A and a third track segment A121B. The first track segment A121A extends from the intersection center A123 along a first direction F1, that is, it extends from the intersection center A123 towards the left side of the vehicle. The third track segment A121B extends from the intersection center A123 along a third direction F3, that is, it extends from the intersection center A123 towards the right side of the vehicle. Therefore, when the first positioning component A110 is in a left-facing lateral usage mode, the second slider A112 is located at the intersection center A123, the first slider A111 is located at the first track segment A121A, and the first positioning component A110 rotates relative to the second positioning component A120 to face the first direction F1 (see Figures 8 and 10). When the first positioning component A110 is in the rightward lateral use mode, the second slider A112 is located at the intersection center A123, the first slider A111 is located at the third track segment A121B, and the first positioning component A110 rotates relative to the second positioning component A120 to face the third direction F3 (see Figures 9 and 11).

[0148] It should be noted that the "left-facing lateral usage mode" mentioned above can be understood as the usage mode in which the first positioning component A110 faces the left side door of the car, that is, the front end of the first positioning component A110 faces the left side door of the car; the "right-facing usage mode" can be understood as the usage mode in which the first positioning component A110 faces the right side door of the car, that is, the front end of the first positioning component A110 faces the right side door of the car.

[0149] It should be noted that, in this embodiment, since the first slider A111 can slide along the first track A121 and the second slider A112 can slide along the second track A122, when the first positioning component A110 rotates relative to the second positioning component A120 to the first direction F1, the front end of the first positioning component A110 will be pulled outward relative to the second positioning component A120 along the first direction F1, that is, the front end of the first positioning component A110 will protrude beyond the left edge of the second positioning component A120 (see Figure 10). When the first positioning component A110 rotates relative to the second positioning component A120 to the third direction F3, the front end of the first positioning component A110 will be pulled outward relative to the second positioning component A120 along the third direction F3, that is, the front end of the first positioning component A110 will protrude beyond the right edge of the second positioning component A120 (see Figure 11). Thus, when the first positioning component A110 is in the side-facing mode, it will be closer to the car door, making it easier for the user to take a child out of or place a child into the vehicle body A200. Since the first slider A111 and the second slider A112 slide synchronously along their corresponding tracks, the first positioning component A110 can simultaneously turn and pull out laterally, eliminating the need for the traditional method of turning first and then pulling out laterally. This improves the convenience of user operation.

[0150] Please refer again to Figures 2 and 3. In one embodiment, the second positioning component A120 is provided with a seatbelt clamp A160. Specifically, the seatbelt clamp A160 is located approximately at the rear end of the second positioning component A120. When the first positioning component A110 is in rear-facing use mode, the user can clamp the seatbelt of the vehicle seat via the seatbelt clamp A160 to improve the safety of the vehicle body A200 after it is installed behind the positioning component A100.

[0151] Referring to Figure 3, in one embodiment, the second positioning component A120 is provided with a blocking member A140. This blocking member A140 can be disposed outside the first track A121 and / or the second track A122 to block the first track A121 and / or the second track A122. Specifically, in this embodiment, the first track segment A121A and the third track segment A121B of the first track A121, as well as the second track A122, are all provided with blocking members A140. The structure of the blocking member A140 outside the first track segment A121A will be briefly described below as an example.

[0152] In one embodiment, as shown in Figures 3 and 4, the blocking member A140 can be a flexible soft structure, which may include a first blocking plate A141 and a second blocking plate A142. The first blocking plate A141 and the second blocking plate A142 are respectively disposed on opposite sides of the first track segment A121A and extend in opposite directions. A sliding gap A143 is provided between the first blocking plate A141 and the second blocking plate A142, which is connected to the first track segment A121A to allow the first sliding member A111 to slide. Specifically, when the first sliding member A111 is located in the sliding gap A143 of the blocking member A140 on the first track segment A121A, under the compression of the first sliding rod A1111, the blocking member A140 undergoes elastic deformation, causing the first blocking plate A141 and the second blocking plate A142 to move away from each other. Optionally, under the pressure of the first sliding rod A1111, the blocking member A140 can deform towards the inside of the first track A121 so as not to affect the rotation of the first positioning component A110 relative to the second positioning component A120; this application is not limited thereto. When the first sliding member A111 moves out of the sliding gap A143 of the blocking member A140 in the first track segment A121A, the blocking member A140 resets, and the first blocking piece A141 and the second blocking piece A142 move closer to each other to re-cover the first track segment A121A. This prevents foreign objects from falling into the first track segment A121A when it is exposed.

[0153] More specifically, as shown in Figure 3, the blocking member A140 may further include a transition piece A144, which is disposed at the end of the first track segment A121A away from the intersection center A123 and connects the first blocking piece A141 and the second blocking piece A142. It should be noted that the first blocking piece A141, the transition piece A144, and the second blocking piece A142 can be integrally formed; of course, in other embodiments, the transition piece A144 can also be connected between the first blocking piece A141 and the second blocking piece A142 by means of bonding or other methods. Connecting the first blocking piece A141 and the second blocking piece A142 via the transition piece A144 improves the ease of placement of the blocking member A140 at each track.

[0154] Referring to Figure 3, in one embodiment, the second positioning component A120 includes a top cover A125A and a bottom cover A125B connected vertically, forming an inner cavity A126 (see Figure 7). A first track A121 and a second track A122 are disposed on the top cover A125A and communicate with the inner cavity A126. Specifically, a first blocking plate A141 and a second blocking plate A142 can be installed on the upper surface of the top cover A125A, i.e., the side facing the first positioning component A110; of course, in other embodiments, the first blocking plate A141 and the second blocking plate A142 can also be installed on the side of the top cover A125A facing the inner cavity A126, without specific limitations.

[0155] Referring again to Figure 3, in this embodiment, a limiting recess A1251 is provided on the side of the top cover A125A facing the first positioning component A110. This limiting recess A1251 is recessed relative to the upper surface of the top cover A125A and surrounds the first track segment A121A. A first blocking piece A141 is installed in the limiting recess A1251 on one side of the first track segment A121A, and a second blocking piece A142 is installed in the limiting recess A1251 on the other side of the first track segment A121A. The thickness of both the first blocking piece A141 and the second blocking piece A142 is less than or equal to the depth of the limiting recess A1251. This effectively prevents interference between the first positioning component A110 and the blocking piece A140 when the first positioning component A110 rotates relative to the second positioning component A120. It should be noted that the first shielding piece A141 and the second shielding piece A142 are installed into the limiting recess A1251 by means including but not limited to adhesive, snap-fit ​​or riveting.

[0156] Referring to Figures 4 and 7, in one embodiment, the first sliding member A111 may include a first sliding rod A1111 and a first slider A1112 connected together, and the second sliding member A112 may include a second sliding rod A1121 and a second slider A1122 connected together. In this embodiment, the first track A121 may include a first channel A1211 and a first groove A1212, and the second track A122 may include a second channel A1221 and a second groove A1222. The first channel A1211 and the second channel A1221 are both located on the lower surface of the top cover A125A, i.e., on the side facing the inner cavity A126. They intersect and communicate with each other, and both the first channel A1211 and the second channel A1221 are connected to the inner cavity A126. The first slide groove A1212 is disposed inside the first channel A1211, and the second slide groove A1222 is disposed inside the second channel A1221. Both the first slide groove A1212 and the second slide groove A1222 are through-slot structures. Therefore, when the first sliding member A111 slides within the first track A121, it can be considered that the first sliding rod A1111 slides within the first slide groove A1212, while the first slider A1112 slides within the first channel A1211. When the second sliding member A112 slides within the second track A122, it can be considered that the second sliding rod A1121 slides within the second slide groove A1222, while the second slider A1122 slides within the second channel A1221.

[0157] More specifically, in this embodiment, as shown in FIG7, the width W1 of the first slider A1112 along the second direction F2 is greater than the width L1 of the first groove A1212, and the width W2 of the second slider A1122 along the first direction F1 or the third direction F3 is greater than the width L2 of the second groove A1222. This prevents the first slider A111 from disengaging from the first track A121 during sliding, and the second slider A112 from disengaging from the second track A122 during sliding, thereby preventing the first positioning component A110 from disengaging from the second positioning component A120 when it rotates or shifts relative to the second positioning component A120.

[0158] Please refer to Figures 12 to 15. In this embodiment, the locking mechanism A130 is disposed on the second positioning component A120, and the locking mechanism A130 is approximately located at the rear end of the second positioning component A120. Specifically, when the first positioning component A110 is in the rearward use mode, the locking mechanism A130 can be considered as being located on the side of the first sliding member A111 away from the second sliding member A112 along the second direction F2. The first positioning component A110 is provided with a locking part A1134 (see Figure 4). The locking part A1134 can be a groove structure or a hole structure, which is mainly used for locking and engaging with the locking mechanism A130. Specifically, in this embodiment, the locking part A1134 is located at the front end of the first positioning component A110, that is, the first sliding member A111 can be considered as being located between the locking part A1134 and the second sliding member A112. Therefore, when the first positioning component A110 is in the rearward use mode and locked to the locking part A1134 by the locking mechanism A130, the front end of the first positioning component A110 is fixed to the second positioning component A120 by the locking mechanism A130. Simultaneously, the middle part of the first positioning component A110 is fixed to the second positioning component A120 by the first sliding member A111, and the rear end of the first positioning component A110 is fixed to the second positioning component A120 by the second sliding member A112. In other words, when the first positioning component A110 is in the rearward use mode, its front end, middle part, and rear end are all supported and fixed by the second positioning component A120, and the first positioning component A110 can be considered to have three fixed support points. These three fixed support points are approximately evenly distributed in the second direction F2, thus greatly improving the stability of the first positioning component A110 in the rearward use mode. It should be noted that, in this embodiment, when the first positioning component A110 is in the rearward use mode, it is locked with the locking part A1134 by the locking mechanism A130. The first sliding member A111 and the second sliding member A112 are respectively located at the ends of the intersection center A123 and the second track A122, thereby restricting the movement of the first positioning component A110 relative to the second positioning component A120 in the first direction F1 and / or the second direction F2. At the same time, it also restricts the first positioning component A110 from disengaging from the second positioning component A120 in a direction perpendicular to the plane containing the first direction F1 and the second direction F2.

[0159] In one embodiment, a protrusion A1291 (see FIG. 8) is formed on the upper surface of the second positioning component A120 (i.e., the upper surface of the top cover A125A), and the protrusion A1291 is located on the side of the intersection center A123 away from the second track A122 along the second direction F2. A protruding limiting protrusion A1292 is formed on the protrusion A1291, and the limiting protrusion A1292 and the upper surface of the top cover A125A form a slot-shaped structure A1293 with an opening. Thus, when the first positioning component A110 is in the rearward use mode, a portion of the circumferential edge of the first positioning component A110 (i.e., the rotating seat A113) can be inserted into this slot-shaped structure A1293 (compare FIG. 2 and FIG. 8). Thus, the groove structure A1293 can further restrict the swaying of the front end of the first positioning component A110 in the approximately vertical direction, while allowing the first positioning component A110 to rotate and slide in the horizontal direction (which can be regarded as the plane containing the first direction F1 and the second direction F2). When the car collides or brakes suddenly, the vehicle body A200 tends to tilt towards the front of the car under the action of inertial force, which causes the first positioning component A110 to tend to detach from the second positioning component A120. By inserting a portion of the circumferential edge of the first positioning component A110 into the groove structure A1293, the groove structure A1293 can press against the first positioning component A110, thereby preventing the vehicle body A200 and the first positioning component A110 from detaching from the second positioning component A120, thus improving the safety of the vehicle body A200. Specifically, in this embodiment, a portion of the locking mechanism A130 is movably disposed within the groove structure A1293 of the protrusion A1291.

[0160] Referring to Figures 12 to 15, in one embodiment, the locking mechanism A130 includes a locking member A131, which is rotatably mounted on the second positioning assembly A120 and has a locked position and an unlocked position. Specifically, when the locking member A131 is in the locked position, it can be inserted into the locking part A1134 to lock into the locking part A1134, thereby restricting the first positioning assembly A110 to a rearward use mode. When the locking member A131 is in the unlocked position, it retracts from the locking part A1134 to release the lock on the locking part A1134, thereby allowing the first positioning assembly A110 to rotate on the second positioning assembly A120 to switch from a rearward use mode to a lateral use mode.

[0161] It should be noted that the locking member A131 can be pivotally connected to the second positioning component A120 to switch between a locked position and an unlocked position. In some embodiments not shown, the locking member A131 can also be slidably disposed on the second positioning component A120 to switch between a locked position and an unlocked position; no specific limitation is made here.

[0162] Referring to Figures 12 and 13, in one embodiment, a support member A127A is provided in the inner cavity A126 of the second positioning component A120, and a locking member A131 is pivotally connected to the support member A127A to switch between a locked position and an unlocked position. Furthermore, a second through hole A1253 (see Figure 8) is provided on the top cover A125A, communicating with the inner cavity A126. Specifically, the second through hole A1253 is located within the groove structure A1292. The second through hole A1253 allows the locking member A131 to extend out of the inner cavity A126. Specifically, as shown in Figure 15, when the locking member A131 is in the locked position, at least a portion of the locking member A131 passes through the second through hole A1253 to insert into the locking portion A1134 of the first positioning component A110. As shown in Figure 14, when the locking member 131 is in the unlocked position, the locking member A131 retracts from the second through hole A1253 into the inner cavity A126 to release the lock on the first positioning assembly A110. More specifically, the locking member A131 may include a connected locking hook portion A1311 and a pivot portion A1312. The pivot portion A1312 can be pivotally connected to the support member A127A via a connector (such as a pin or rivet). The locking hook portion A1311 extends out of the second through hole A1253 to engage with the locking portion A1134 for locking or insertion.

[0163] Referring to Figures 12 and 13, in one embodiment, a support bracket A127B is further provided in the inner cavity A126 of the second positioning component A120. This support bracket A127B supports the aforementioned support member A127A. Specifically, the support bracket A127B includes two support base rods A1273 arranged side-by-side along a first direction F1 or a third direction F3, and a support crossbar A1274 fixed between the two support base rods A1273. The support member A127A is fixedly mounted on the support crossbar A1274. Of course, in other embodiments, the support bracket A127B can be omitted, and the support member A127A can be directly installed in the inner cavity A126. Specifically, in this embodiment, the support member A127A includes two support plates A1271, which are spaced apart along the length of the support crossbar A1274. Each support plate A1271 has a protruding connecting branch A12711 on its opposite side. The pivot portion A1312 of the locking member A131 is pivotally connected between the two connecting branches A12711 via a connector. More specifically, a reinforcing plate A1272 is also provided between the two support plates A1271. The reinforcing plate A1272 has a first through hole A12721 corresponding to the position of the second through hole A1253. As shown in FIG15, when the locking member A131 is in the locked position, the locking hook portion A1311 of the locking member A131 will pass through the first through hole A12721 and the second through hole A1253 in sequence and be inserted into the locking portion A1134 of the first positioning component A110. In this embodiment, by adding a reinforcing plate A1272 between the two support plates A1271, the strength of the groove wall of the groove structure A1293 can be improved, thereby increasing the fixing strength of the groove structure A1293 to the first positioning component A110 and the locking strength of the locking mechanism A130.

[0164] To facilitate user control of the position of the locking element A131, referring to Figures 3, 12, and 13, in one embodiment, the positioning component A100 further includes a release mechanism A150. This release mechanism A150 is correspondingly and movably disposed on the second positioning component A120. The release mechanism A150 is operably connected to the locking element A131 to allow the locking element A131 to switch from a locked position to an unlocked position. Specifically, as shown in Figures 12 and 13, the release mechanism A150 includes a release operation element A151 and a traction element A152. The release operation element A151 is movably disposed on the second positioning component A120; for example, the release operation element A151 is slidably disposed on the second positioning component A120. The traction element A152 is connected between the release operation element A151 and the locking element A131. Therefore, when the release mechanism A151 is operated (e.g., pushed or pulled), the release mechanism A151 can move relative to the second positioning component A120 to drive the traction component A152 to move, thereby driving the locking component A131 to switch from the locked position to the released position. More specifically, the locking component A131 also includes a driving part A1313, which is used to connect with the traction component A152. Specifically, the driving part A1313 and the locking hook part A1311 are located on both sides of the pivot part A1312, so when the release mechanism A151 pulls the driving part A1313 to rotate around the connector via the traction component A152, the locking hook part A1311 can rotate around the connector simultaneously with the driving part A1313 to switch from the locked position to the released position.

[0165] Referring to Figures 3, 12, and 13, in this embodiment, a fixing seat A128 is further provided in the inner cavity A126 of the second positioning component A120. This fixing seat A128 is used to support the release operation member A151. Specifically, the top cover A125A is provided with an operation hole A1252, which corresponds to the fixing seat A128. More specifically, the release operation member A151 is slidably disposed on the fixing seat A128. The release operation member A151 has a gripping part A1511, which passes through the operation hole A1252 and protrudes from the upper surface of the top cover A125A to facilitate user operation.

[0166] Specifically, referring to Figures 14 and 15, in this embodiment, the locking mechanism A130 further includes a first reset member A132. The first reset member A132 can be, for example, an elastic component such as a spring or a spring sheet, which mainly abuts against the locking member A131 to drive the locking member A131 to remain in the locked position. When the user does not apply a pushing or pulling force to the release operation member A151, the driving part A1313 of the locking member A131 is not under force, thus the first reset member A132 can drive the locking member A131 to pivot and reset to the locked position around the connecting member. Furthermore, in this embodiment, as shown in Figures 12 and 13, the release operation mechanism A150 also includes a second reset member A153. The second reset member A153 can also be, for example, an elastic component such as a spring or a spring sheet, which mainly abuts against the release operation member A151 to reset the release operation member A151. Specifically, the fixed base A128 is provided with a mounting groove A1281, and the second reset member A153 is accommodated within the mounting groove A1281. The release operation member A151 is provided with an abutment portion A1512, which is movably inserted into the mounting groove A1281 and abuts against the second reset member A153. It should be noted that, in this embodiment, the extending direction of the mounting groove A1281 is parallel to the moving direction of the release operation member A151. The mounting groove A1281, through the abutment portion A1512, can also be used to guide the movement of the release operation member A151, preventing the release operation member A151 from deviating during movement.

[0167] Figure 16 shows a perspective view of a first positioning component A110 in a positioning component A100 provided according to a second embodiment of the first aspect of the present invention, and Figure 17 shows a top view of a second positioning component A120 in a positioning component A100 provided according to a second embodiment of the first aspect of the present invention. This positioning component A100 is similar to the first embodiment of the first aspect described above, including components such as the first positioning component A110 and the second positioning component A120. The positioning component A100 of this embodiment is a variation of the positioning component A100 of the first embodiment of the first aspect described above. Unless otherwise specified, the structure of the components and the connection relationships between the components in this embodiment can be referred to the description in the first embodiment of the first aspect described above. The following mainly describes the differences between this embodiment and the first embodiment of the first aspect described above.

[0168] In the second embodiment of the first aspect, as shown in FIG16, for the first positioning component A110, when the first slider A111 is at the rotation axis, the second slider A112 can also be disposed at the front end of the first positioning component A110. At this time, the second slider A112 can be regarded as being located between the locking part A1134 and the first slider A111. As shown in FIG17, for the second positioning component A120, the first track A121 still extends along the first direction F1 or the third direction F3, while the second track A122 extends along the fourth direction F4. It should be noted that the fourth direction F4 can be regarded as the rear direction of the car (i.e., the direction towards the rear of the car), which is parallel to and opposite to the second direction F2. At this time, when the first slider A111 slides along the first track A121 and the second slider A112 slides along the second track A122, the first positioning component A110 can still switch between the rearward use mode and the side use mode on the second positioning component A120.

[0169] It should be noted that in some embodiments not shown, the locking mechanism A130 may also be located at the front end of the second positioning component A120 along the second direction F2, for example, near the position of the support leg A124B. Correspondingly, the rear end of the first positioning component A110 is provided with a locking part A1134, so that the locking member A131 can also lock and cooperate with the locking part A1134 to lock the first positioning component A110 in the rearward use mode. Of course, in other embodiments, multiple locking mechanisms A130 may be provided, such as two. Specifically, a locking mechanism A130 may be provided at the front end (i.e., near the position of the support leg A124B) and the rear end of the second positioning component A120 along the second direction F2. Correspondingly, the front end and the rear end of the first positioning component A110 are respectively provided with locking parts A1134. This application is not limited to this.

[0170] A third embodiment of the first aspect of the present invention also provides a positioning component A100. This positioning component A100 is similar to the first embodiment of the first aspect described above, and can be considered a variation of the positioning component A100 of the first embodiment of the first aspect. Therefore, unless otherwise specified, the structure of the components and the connection relationships between the components in this embodiment can be referred to the description in the first embodiment of the first aspect above. The following mainly describes the differences between this embodiment and the first embodiment of the first aspect described above.

[0171] In the third embodiment of the first aspect, for the second positioning component A120, the first track A121 extends along a first direction F1 or a third direction F3, while the second track A122 extends along a fourth direction F4 (see the second positioning component A120 in the second embodiment). For the first positioning component A110, the positions of the first slider A111 and the second slider A112 are the same as in the first embodiment, i.e., the first slider A111 is located at the rotation axis of the first positioning component A110, and the second slider A112 is located at the rear end of the first positioning component A110, which can be considered as the second slider A112 being located behind the first slider A111. The first slider A111 slides along the first track A121, and the second slider A112 slides along the second track A122. When the first slider A111 is located at the intersection center A123 and the second slider A112 is located on the second track A122, the first positioning component A110 is in a forward-facing mode, that is, the front end of the first positioning component A110 faces the front of the car. When the second slider A112 is located at the intersection center A123 and the first slider A111 is located on the first track A121, the first positioning component A110 is in a lateral mode.

[0172] In this embodiment, the first positioning component A110 has a forward-facing mode and a side-facing mode. Considering the safety of infants and young children riding in vehicles, the vehicle body A200 used in this embodiment is mostly a seat, which is suitable for older children.

[0173] Figure 18 shows a perspective view of a vehicle B1000 provided according to a second aspect of the present invention, and Figure 19 shows a perspective view of the vehicle B1000 provided according to another perspective of a second aspect of the present invention. The vehicle B1000 may include a vehicle body B200 and a positioning component B100 provided according to a second aspect of the present invention. The vehicle body B200 is connected to the positioning component B100, which is used to connect to a car seat (not shown). In other words, the vehicle body B200 can be mounted to a car seat via the positioning component B100, thereby improving the safety of children or infants riding in a car. The vehicle body B200 and the positioning component B100 will be described below concurrently with the description of the vehicle B1000.

[0174] In one embodiment, the carrier body B200 can be, for example, a baby carrier (see Figures 18 and 19), a seat (not shown), or a sleeping box (not shown) for carrying infants; or it can be a pet carrier (not shown) for carrying animals. It should be noted that the bottom of the carrier body B200, such as the baby carrier or seat, is usually provided with a locking member B230 (see Figure 20). These locking members B230 are mainly used to connect with the connecting mechanism B116 of the positioning component B100 (see Figure 29, the specific structure is described below), thereby realizing a quick connection between the carrier body B200 and the positioning component B100.

[0175] Specifically, in this embodiment, the carrier body B200 is a baby carrier, primarily used to carry infants weighing no more than 35 pounds or with a height no more than 87 cm. As shown in Figure 20, the carrier body B200 generally includes a seat portion B210 and a backrest portion B220 connected and angled together. The seat portion B210 primarily supports the infant's buttocks and legs, and a locking element B230 is provided at the bottom of the seat portion B210. The backrest portion B220 supports the infant's back and head, and a guide portion B221 is provided in the backrest portion B220. This guide portion B221 is generally a recessed structure and extends upwards in a direction away from the seat portion B210. More specifically, an abutting protrusion B222 is formed at the end of the guide portion B221 away from the seat portion B210.

[0176] Referring to Figures 21 and 22, in one embodiment, the positioning component B100 may include a first positioning component B110 and a second positioning component B120. The first positioning component B110 is used for locking connection with the vehicle body B200, and the second positioning component B120 is used for connecting to the vehicle seat. One of the first positioning component B110 and the second positioning component B120 is provided with a first track B121 and a second track B122, and the other of the first positioning component B110 and the second positioning component B120 is provided with a first slider B111 and a second slider B112. Specifically, the first track B121 and the second track B122 are intersecting to form a T-shape. The first slider B111 slides along the first track B121, and the second track B122 slides along the second track B122. In this way, the first positioning component B110 can rotate and displace relative to the second positioning component B120 simultaneously. Furthermore, due to the T-shaped structure, the first positioning component B110 can operate in a rearward mode (see Figures 18 and 19) and a lateral mode (see Figures 24 and 25) on the second positioning component B120. It should be noted that the first track B121 and the second track B122 are connected, and the first slider B111 and the second slider B112 are spaced apart.

[0177] It should also be noted that when the positioning component B100 is installed on the car seat, with the car as a reference, the "rearward use mode" refers to the state in which the first positioning component 110 faces the rear of the car. The "side use mode" refers to the state in which the first positioning component B110 faces the car door, which includes two states: facing the left door or the right door.

[0178] In this embodiment, the first positioning component B110 is provided with a first sliding member B111 and a second sliding member B112, and the second positioning component B120 is provided with a first track B121 and a second track B122. The structure and working principle of the positioning component B100 are briefly described below.

[0179] Referring to Figures 21 and 22, in one embodiment, the first positioning component B110 includes a connecting seat B114 for connecting to and supporting the vehicle body B200. Specifically, in this embodiment, the connecting seat B114 is detachably connected to the vehicle body B200. The connecting seat B114 may include, for example, a connecting portion B1141 and a support portion B1142 that are connected or integrally formed. The support portion B1142 extends upward at an angle relative to the connecting portion B1141, such that the support portion B1142 and the connecting portion B1141 are arranged at an angle. More specifically, an open mounting space B1143 is formed between the support portion B1142 and the connecting portion B1141, which is used to accommodate the seat portion B210 of the vehicle body B200 (see Figures 18 and 21). Specifically, the connecting part B1141 is provided with a connecting mechanism B116 (the specific structure and working principle can be found in the following text), and the first positioning component B110 is detachably connected to the vehicle body B200 through the connecting mechanism B116.

[0180] Referring to Figure 21, for the first positioning component B110, the connecting part B1141 is generally a long strip structure, and the supporting part B1142 is disposed at one end of the connecting part B1141. Specifically, in this embodiment, the position of the supporting part B1142 is referred to as the rear end of the first positioning component B110. Then, the position of the end of the connecting part B1141 away from the supporting part B1142 can be regarded as the front end of the first positioning component B110, and the front end and the rear end of the first positioning component B110 are arranged approximately along the same straight line opposite each other. In this embodiment, the supporting part B1142 can be used to guide the carrier body B200 to be installed on the connecting seat B114. Specifically, during the process of installing the carrier body B200 into the installation space B1143, the supporting part B1142 can cooperate with the guide part B221 on the carrier body B200 to guide the carrier body B200 to quickly and accurately dock with the connecting mechanism B116. After the carrier body B200 is connected to the connecting mechanism B116 on the connecting part B1141, the end of the support part B1142 away from the connecting part B1141 can abut against the abutting protrusion B222 of the carrier body B200 to support the back part B220 of the carrier body B200 (refer to Figures 18 to 20). In this way, the stability of the carrier body B200 installed on the first positioning assembly B110 can be improved.

[0181] To better understand the front and rear ends of the first positioning component B110, referring to Figures 18 and 19, taking the vehicle body B200 installed on the first positioning component B110 as an example, the front end of the first positioning component B110 refers to the end away from the backrest portion B220 of the vehicle body B200, and the rear end of the first positioning component B110 refers to the end closer to the backrest portion B220 of the vehicle body B200. When an infant or toddler is seated inside the vehicle body B200, the front end of the first positioning component B110 is closer to the infant or toddler's feet than the rear end, and the rear end of the first positioning component B110 is closer to the infant or toddler's head than the front end.

[0182] Referring again to Figures 21 and 22, in one embodiment, the first positioning component B110 further includes a rotating seat B113. Specifically, a connecting seat B114 is pivotally connected to the rotating seat B113. Therefore, the connecting seat B114 can pivot relative to the rotating seat B113, and during pivoting, the connecting seat B114 can be angularly adjusted relative to the rotating seat B113. Thus, when the carrier body B200 is mounted on the connecting seat B114, the tilt angle of the carrier body B200 relative to the second positioning component B120 can be adjusted by adjusting the tilt angle of the connecting seat B114 relative to the rotating seat B113, thereby improving the comfort of the infant riding in the carrier body B200. Of course, in other embodiments, the rotating seat B113 may be omitted; or, the connecting seat B114 may be integrally formed with the rotating seat B113, without specific limitations.

[0183] In this embodiment, the rotary seat B113 has a rotation axis. A first sliding member B111 is disposed on the rotary seat B113 and coaxially with the rotation axis, while a second sliding member B112 is offset from the rotation axis. Specifically, in this embodiment, the rotary seat B113 is approximately circular, and the rotation axis can be considered the center of the rotary seat B113. The connecting seat B114 extends approximately along the radial direction of the rotary seat B113. Of course, in other embodiments, the rotary seat B113 can also be other symmetrical shapes (such as ellipse, rectangle, etc.), and the rotation axis can be the geometric center of the rotary seat B113 or a position offset from the geometric center; alternatively, the rotary seat B113 can also be asymmetrical, and the rotation axis can be set according to actual needs.

[0184] Specifically, in this embodiment, as shown in FIG22, the first slider B111 and the second slider B112 are located on the lower surface of the first positioning component B110, that is, on the side of the rotating seat B113 opposite to the connecting seat B114. The first slider B111 is approximately coaxially arranged with the rotation axis of the rotating seat B113 (i.e., the first slider B111 can be considered to be located at the rotation axis), and the second slider B112 is approximately located below the support portion B1142, which can be considered to be located at the rear end of the first positioning component B110. Therefore, from an overall perspective, the first slider B111 can be considered to be located in the middle of the first positioning component B110, and the second slider B112 can be considered to be located at the rear end of the first positioning component B110 and behind the first slider B111.

[0185] Therefore, it should be emphasized that the "state in which the first positioning component B110 faces the rear of the vehicle" mentioned above refers to the state in which the front end of the first positioning component B110 faces the rear of the vehicle and the rear end of the first positioning component B110 faces the front of the vehicle. In this case, when the infant is seated inside the vehicle body B200 mounted on the first positioning component B110, the infant's face is facing the rear of the vehicle. Similarly, the "state in which the first positioning component B110 faces the vehicle door" refers to the state in which the front end of the first positioning component B110 faces the vehicle door. In this case, when the infant is seated inside the vehicle body B200 mounted on the first positioning component B110, the infant's face is facing the vehicle door.

[0186] Referring to Figure 22, in one embodiment, the first track B121 on the second positioning component B120 extends along either the first direction F1 or the third direction F3, and the second track B122 extends along the second direction F2. The first direction F1 and the third direction F3 are parallel and opposite, and the second direction F2 intersects the first direction F1; specifically, the second direction F2 is perpendicular to the first direction F1. Considering the installation of the positioning component B100 on the car seat, the first direction F1 can be considered the left side of the car (i.e., the direction towards the left side door), the second direction F2 can be considered the front side of the car (i.e., the direction towards the front of the car), and the third direction F3 can be considered the right side of the car (i.e., the direction towards the right side door).

[0187] Please refer to Figure 22. In this embodiment, the intersection of the first track B121 and the second track B122 is referred to as the intersection center B123. Regarding the first positioning component B110, when the positioning component B100 is installed on the car seat, as shown in Figure 21, if the first positioning component B110 is in a rear-facing mode, it can be considered to have rotated relative to the second positioning component B120 to face away from the second direction F2. At this time, the first slider B111 is located at the intersection center B123, and the second slider B112 is located on one side of the first slider B111 along the second direction F2, that is, the second slider B112 can be considered to be located in front of the first slider B111 along the second direction F2, and the second slider B112 is located on the second track B122 (see Figure 23). As shown in Figures 24 and 25, when the first positioning component B110 is in the lateral use mode, the first positioning component B110 can be considered to be rotated relative to the second positioning component B120 to face either the first direction F1 or the third direction F3. At this time, the second slider B112 is located at the intersection center B123, and the first slider B111 is located on the first track B121 (see Figures 26 and 27).

[0188] Specifically, in this embodiment, as shown in FIG22, the intersection center B123 can be regarded as dividing the first track B121 into a connected first track segment B121A and a third track segment B121B. The first track segment B121A extends from the intersection center B123 along a first direction F1, that is, it extends from the intersection center B123 towards the left side of the vehicle; the third track segment B121B extends from the intersection center B123 along a third direction F3, that is, it extends from the intersection center B123 towards the right side of the vehicle. Therefore, when the first positioning component B110 is in a left-facing lateral usage mode, the second slider B112 is located at the intersection center B123, the first slider B111 is located at the first track segment B121A, and the first positioning component B110 rotates relative to the second positioning component B120 to face the first direction F1 (referencing FIG24 and FIG26), with the front end of the first positioning component B110 extending to the left. When the first positioning component B110 is in the rightward lateral use mode, the second slider B112 is located at the intersection center B123, the first slider B111 is located at the third track segment B121B, the first positioning component B110 rotates relative to the second positioning component B120 to face the third direction F3 (refer to Figures 25 and 27), and the front end of the first positioning component B110 extends to the right.

[0189] It should be noted that the "left-facing lateral use mode" mentioned above can be understood as the use mode in which the first positioning component B110 faces the left side door of the car, that is, the front end of the first positioning component B110 faces the left side door of the car; the "right-facing lateral use mode" can be understood as the use mode in which the first positioning component B110 faces the right side door of the car, that is, the front end of the first positioning component B110 faces the right side door of the car.

[0190] Referring again to Figures 21 and 22, in one embodiment, the first positioning component B110 has a connecting mechanism B116, which is disposed on the connecting seat B114 and has a locked state and an unlocked state. Specifically, when the connecting mechanism B116 is in the locked state, it is adapted to engage with the engaging member B230 of the carrier body B200 to securely mount the carrier body B200 onto the first positioning component B110. When the connecting mechanism B116 is in the unlocked state, it releases the lock on the engaging member B230 of the carrier body B200, allowing the carrier body B200 to disengage from the first positioning component B110.

[0191] Referring to Figures 29 and 30, in one embodiment, the connecting mechanism B116 includes a locking member B1161. The locking member B1161 is pivotally connected to the connecting seat B114 and has a locked position and an unlocked position. Specifically, when the locking member B1161 is in the locked position, it engages with the engaging member B230 of the vehicle body B200. When the locking member B1161 is in the unlocked position, it releases the restriction on the engaging member B230 of the vehicle body B200, allowing the engaging member B230 to disengage from the locking member B1161. Specifically, in this embodiment, the locking member B1161 is pivotally connected to the connecting portion B1141 of the connecting seat B114, which has a slot B11411 for accommodating the engaging member B230 of the vehicle body B200. Locking member B1161 is pivotally connected to slot B11411 to close the opening of slot B11411, thereby limiting the engaging member B230 at the bottom of the vehicle body B200 within slot B11411, ultimately achieving a detachable connection between the vehicle body B200 and the first positioning assembly B110. More specifically, when locking member B1161 is in the locked position, locking member B1161 extends at least partially into slot B11411 to seal the opening of slot B11411 (as shown in Figure 29). This confines engaging member B230 within slot B11411, achieving a locking engagement between locking member B1161 and engaging member B230. When locking member B1161 is in the unlocked position, locking member B1161 retracts from slot B11411, opening the opening of slot B11411 (as shown in Figure 30). In this way, the engaging member B230 can disengage from the slot of the slot B11411. Specifically, in this embodiment, the locking member B1161 is generally a hook-shaped structure with a U-shaped hook groove B11612. The hook groove B11612 has a push wall B11613, which is adapted to be pushed by the engaging member B230 to drive the locking member B1161 to pivot from the unlocked position to the locked position.

[0192] Specifically, in this embodiment, the bottom of the vehicle body B200 is typically provided with at least two engaging members B230 along the front-rear direction. Correspondingly, the connecting portion B1141 has at least two rows of slots B11411, and the distance between two adjacent rows of slots B11411 is approximately equal to the distance between two adjacent engaging members B230 at the bottom of the vehicle body B200. When the vehicle body B200 is installed onto the first positioning component B110, the two adjacent rows of slots B11411 engage with the two adjacent engaging members B230 respectively. Specifically, referring to Figures 20 and 21, in this embodiment, the bottom of the vehicle body B200 is provided with two engaging members B230, and the connecting portion B1141 has two rows of slots B11411, with each row of slots B11411 including two slots B11411. Each engaging member B230 engages with the two slots B11411 of each row of slots B11411. Correspondingly, the connecting part B1141 is provided with four locking members B1161, and each slot B1132 corresponds to one locking member B1161 (see Figures 29 and 30). It should be noted that in other embodiments, the bottom of the vehicle body B200 may also be provided with three, four or more engaging members B230, and the connecting part B1141 may also have three, four or more rows of locking members B1161, which is not specifically limited here.

[0193] Referring to Figures 29 to 31, in one embodiment, the connecting mechanism B116 may further include a locking retainer B1162, which is movably disposed on the connecting seat B114 and has a locked position and an unlocked position. When the first positioning component B110 is in the lateral use mode, the movement direction of the locking retainer B1162 is parallel to the first direction F1 or the third direction F3; when the first positioning component B110 is in the rearward use mode, the movement direction of the locking retainer B1162 is parallel to the second direction F2. Specifically, when the locking retainer B1162 is in the locked position, it restricts the pivoting of the locking member B1161 to keep it in the locked position. When the locking retainer B1162 is in the unlocked position, it allows the locking member B1161 to pivot to switch to the unlocked position.

[0194] Referring to Figures 29 and 30, in one embodiment, one of the locking member B1161 and the locking retainer B1162 is provided with a locking groove B11611, and the other is provided with a blocking portion B11621. Specifically, in this embodiment, the locking member B1161 is provided with a locking groove B11611, and the locking retainer B1162 is provided with a blocking portion B11621. When the locking retainer B1162 is in the locked position, the blocking portion B11621 engages with the locking groove B11611 (see Figure 29) to lock the locking member B1161 in the locked position, thus making the connecting mechanism B116 appear to be in a locked state. When the locking retainer B1162 is in the unlocked position, the blocking portion B11621 disengages from the locking groove B11611 (see Figure 30) to allow the locking member B1161 to switch between the locked position and the unlocked position, thus making the connecting mechanism B116 appear to be in an unlocked state. It should be noted that, in this embodiment, the locking retainer B1162 is provided with four blocking parts B11621, each blocking part B11621 being used to lock into the locking groove B11611 of each locking member B1161 respectively.

[0195] In one embodiment, the connecting mechanism B116 further includes a first reset member B1163 (see FIG. 30) and a second reset member B1164 (see FIG. 31). The first reset member B1163 may be, for example, an elastic element such as a spring, torsion spring, or sheet spring, and is used to abut against the locking member B1161 to hold the locking member B1161 in the unlocked position. Similarly, the second reset member B1164 may be, for example, an elastic element such as a spring or sheet spring, and is used to abut against or connect with the locking retainer B1162 to give the locking retainer B1162 a constant tendency to move towards the locked position.

[0196] Referring to Figures 24 and 25, in one embodiment, the positioning component B100 may further include a release mechanism B130, which is disposed on the connecting seat B114 of the first positioning component B110, specifically on the connecting portion B1141 and / or the support portion B1142 of the connecting seat B114. The release mechanism B130 is drivenly connected to the connecting mechanism B116 (specifically, the locking retainer B1162), thus allowing the user to adjust the state of the connecting mechanism B116 by operating the release mechanism B130. Specifically, the release mechanism B130 includes a first release member B131 and a second release member B132 that are movably configured. The first release member B131 and the second release member B132 are respectively drivenly connected to the connecting mechanism B116 (specifically, the locking retainer B1162) (the specific driving principle is explained later). In this way, the user can control the state of the connecting mechanism B116 by operating the first release member B131 and the second release member B132, thereby realizing the detachable connection between the first positioning component B110 and the vehicle body B200.

[0197] In one embodiment, when the vehicle body B200 is not installed on the first positioning component B110, when the first positioning component B110 is in a rearward use mode (as shown in FIG. 21), either the first unlocking member B131 or the second unlocking member B132 can be operated, thereby changing the state of the connecting mechanism B116. When the first positioning component B110 is in a lateral use mode (as shown in FIG. 24 or FIG. 25), either the second unlocking member B132 or the first unlocking member B131 can be operated, thereby similarly releasing the lock of the first positioning component B110 on the vehicle body B200. When the vehicle body B200 is installed on the first positioning component B110, if it is necessary to remove the vehicle body B200 from the first positioning component B110, the user can selectively operate the more convenient one of the first unlocking member B131 and the second unlocking member B132 to perform the unlocking operation. In other words, when the first positioning component B110 is in the rearward use mode (as shown in Figure 18), the user can easily operate either the first release component B131 or the second release component B132 to release the connecting mechanism B116, thus switching the connecting mechanism B116 from the locked state to the unlocked state. When the first positioning component B110 is in the lateral use mode (as shown in Figure 24 or Figure 25), the user can easily operate the other of the first release component B131 and the second release component B132 to similarly release the connecting mechanism B116, thus switching the connecting mechanism B116 from the locked state to the unlocked state.

[0198] Specifically, in this embodiment, as shown in Figures 24 and 25, the first unlocking member B131 is movably disposed at the end of the connecting portion B1141 away from the support portion B1142 and located within the mounting space B1143. The second unlocking member B132 is movably disposed on the side of the support portion B1142 opposite to the mounting space B1143. The first unlocking member B131 and the second unlocking member B132 are distributed approximately along the same straight line relative to the first positioning component B110 as a whole. Optionally, the first unlocking member B131 and the second unlocking member B132 are distributed approximately along the length direction of the connecting seat B114, with the first unlocking member B131 located at the front end of the first positioning component B110 and the second unlocking member B132 located at the rear end of the first positioning component B110. When the vehicle body B200 is mounted on the first positioning component B110, and the first positioning component B110 is in the rearward use mode, the second release member B132 is exposed relative to the vehicle body B200 (as shown in Figure 18), making it easier to operate the second release member B132 to release the first positioning component B110 from locking the vehicle body B200. When the first positioning component B110 is in the lateral use mode, the first release member B131 extends laterally along with the front end of the first positioning component B110 (see Figure 28), facilitating user operation of the first release member B131 to release the connecting mechanism B116 from locking the vehicle body B200.

[0199] Referring to Figures 24 and 25, specifically, in this embodiment, the row of slots B11411 near the front end of the first positioning component B110 is referred to as the front row of slots B11411, and the row of slots B11411 near the rear end of the first positioning component B110 is referred to as the rear row of slots B11411. The first unlocking member B131 is located near the front row of slots B11411, and the support portion B1142 is located behind the rear row of slots B11411. Thus, the first unlocking member B131 can be considered as the front-end unlocking member on the first positioning component B110, and the second unlocking member B132 can be considered as the rear-end unlocking member on the first positioning component B110. Therefore, when the first positioning component B110 is in a side-use mode, such as a right-side side-use mode (see Figure 28), the first unlocking member B131 will rotate with the front end of the first positioning component B110 to face the third direction F3 and directly face the user standing on the right side door. At the same time, the front end of the first positioning component B110 will be pulled outward relative to the second positioning component B120 along the third direction F3, that is, the front end of the first positioning component B110 will protrude beyond the right edge of the second positioning component B120 (see Figure 28). The first unlocking member B131 located at the front end of the first positioning component B110 will also extend laterally relative to the second positioning component B120. At this time, the second unlocking member B132 will rotate to face the first direction F1 and face away from the user. In this mode, the first release element B131 is more convenient for the user to operate. The user can use one hand to select and operate the first release element B131 to complete the release action, while using the other hand to pick up the vehicle body B200 to remove the vehicle body B200 from the positioning component B100. Conversely, when the first positioning component B110 is in the rear-facing use mode (see Figure 18), the first release element B131 will rotate with the first positioning component B110 to face away from the second direction F2, that is, the first release element B131 is closer to the car seat back and is located between the vehicle body B200 and the car seat back; at the same time, the second release element B132 will rotate to face the second direction F2, so that the second release element B132 is further away from the car seat back relative to the first release element B131. In addition, since the second release element B132 is located on the side of the support part B1142 away from the mounting space B1143, it always remains exposed. At this point, it is more convenient for the user standing at the door to operate the second release component B132, which can be used to complete the unlocking action. It is evident that the positioning component B100 in this embodiment is highly convenient to use. When using it, the user can flexibly select either the first release component B131 or the second release component B132 to complete the unlocking action based on the usage mode or orientation of the first positioning component B110.

[0200] Referring to Figures 31 to 33, in one embodiment, the first unlocking member B131 and the locking retainer B1162 move in parallel directions. The first unlocking member B131 has a pushing protrusion B1312, and the locking retainer B1162 has a pushing protrusion B11622, with the pushing protrusion B1312 abutting against the pushing protrusion B11622. Therefore, when the first unlocking member B131 is operated, the pushing protrusion B1312 can drive the pushing protrusion B11622 to move, thereby causing the locking retainer B1162 to move from the locked position to the unlocked position (switching from Figure 29 to Figure 30). Of course, in other embodiments, as shown in Figure 34, one of the first unlocking member B131 and the locking retainer B1162 has a pushing protrusion B11622, and the other has a pushing recess B1313, with the pushing protrusion B11622 movably inserted into the pushing recess B1313. For example, the first unlocking member B131 has a pushing recess B1313, and the locking retainer B1162 has a pushing protrusion B11622. The pushing recess B1313 is generally a strip-shaped groove, and the length direction of the strip-shaped groove is parallel to the moving direction of the first unlocking member B131. When the first unlocking member B131 is operated, the first unlocking member B131 engages with the pushing protrusion B11622 through the side wall of the pushing recess B1313, thereby causing the locking retainer B1162 to switch from the locked position to the unlocked position.

[0201] Referring to Figures 25, 28 to 31, the following is a brief explanation of the unlocking principle of the first unlocking component B131, taking the first positioning component B110 in a rightward lateral usage mode as an example.

[0202] Specifically, when the first positioning component B110 is in the rightward lateral use mode, the first release member B131 faces the third direction F3, and the second release member B132 faces the first direction F1. The movement direction of the first release member B131 and the locking retainer B1162 is parallel to the first direction F1 or the third direction F3. At this time, the pushing protrusion B11622 is located in front of the pushing protrusion B1312 along the third direction F3 and abuts against the pushing protrusion B1312. Therefore, when the user pulls the first release member B131 along the third direction F3, the pushing protrusion B1312 moves accordingly. The pushing protrusion B1312 pushes the pushing protrusion B11622 to move along the third direction F3, thereby causing the locking retainer B1162 to switch from the locked position to the unlocked position, so that the blocking part B11621 of the locking retainer B1162 disengages from the locking groove B11611 of the locking member B1161. When the blocking part B11621 retracts from the locking groove B11611, under the action of the first reset part B1163, the locking part B1161 can automatically pivot from the locked position to the unlocked position, thereby completing the unlocking action.

[0203] Referring to Figures 31 and 32, in this embodiment, the locking retainer B1162 is generally a plate-like structure, and a notch B11623 is formed at one end of the locking retainer B1162 near the first locking member B1161. The first unlocking member B131 is slidably disposed within the notch B11623. Specifically, a pushing protrusion B1312 is provided on each of the left and right sides of the first unlocking member B131, and a pushing protrusion B11622 is provided on each of the opposite sides of the notch B11623. The two pushing protrusions B11622 correspond to and abut against the two pushing protrusions B1312, respectively. Therefore, when the first unlocking member B131 is operated (e.g., pulled), the first unlocking member B131 can simultaneously drive the two pushing protrusions B11622 to move. This design increases the stability of the locking retainer B1162 during movement, thereby significantly improving the reliability of the unlocking process.

[0204] Please refer to Figures 31 to 33. In one embodiment, the first unlocking member B131 is further provided with a guide groove B1311, which extends along the moving direction of the first unlocking member B131. A guide post B117 is provided within the connecting portion B1141, and the guide post B117 is inserted into the guide groove B1311. Through the guiding engagement of the guide post B117 and the guide groove B1311, deviation of the first unlocking member B131 during movement can be avoided. In this embodiment, there are two guide grooves B1311, distributed on the left and right sides of the first unlocking member B131. There are also two guide posts B117, each guiding and engaging with its corresponding guide groove B1311, but this is not a limitation. More specifically, each guide groove B1311 is provided with a third reset member B133, which may be, for example, a spring. It is mainly used to provide elastic restoring force to the first release member B131 so that it can be automatically reset after the user releases the first release member B131 for the next operation.

[0205] In one embodiment, the second release member B132 can be directly driven connected to the locking retainer B1162. Alternatively, the second release member B132 can be indirectly driven connected to the locking retainer B1162. Specifically, in this embodiment, as shown in Figures 31 and 32, the release mechanism 130 further includes a traction component B134, which is connected between the second release member B132 and the locking retainer B1162. When the second release member B132 is operated, it drives the locking retainer B1162 to switch from a locked position to an unlocked position via the traction component B134. Specifically, the traction component B134 is a flexible element, comprising a traction rope B1341 and a traction sleeve B1342 movably sleeved outside the traction rope B1341. The traction sleeve B1342 is a flexible cord sleeve with a first sleeve end B13421 and a second sleeve end B13422. The traction rope B1341 has a first rope end B13411 adjacent to the first sleeve end B13421 and a second rope end B13412 adjacent to the second sleeve end B13422. Specifically, the first rope end B13411 of the traction rope B1341 is connected to the support part B1142, the second rope end B13412 of the traction rope B1341 is connected to the locking retainer B1162, the first sleeve end B13421 of the traction sleeve B1342 is connected to the second release member B132, and the second sleeve end B13422 of the traction sleeve B1342 is connected to the connecting seat B114 (e.g., the connecting part B1141 or the support part B1142). Thus, when the second release member B132 is operated (e.g., pushed or pulled) to move in the S1 direction, the second release member 132B will drive the traction sleeve B1342 to deform, causing the traction rope B1341 to pull the locking retainer B1162 to move from the locked position to the unlocked position in the S2 direction. It should be noted that, in this embodiment, "moving in the S1 direction" means moving downward along the extension direction of the support portion B1142; "S2 direction" means moving along the extension direction of the connecting portion B1141.

[0206] It should also be noted that in this embodiment, the traction rope B1341 and traction sleeve B1342 shown in Figures 31 and 32 may be obscured by some components (such as the locking retainer B1162). To clearly show the location of the traction rope B1341 and traction sleeve B1342, the obscured parts are shown in the figures with dashed lines.

[0207] The following section, with reference to relevant diagrams, briefly explains the usage process and working principle of the positioning component B100 in this application.

[0208] When the vehicle body B200 is not installed on the first positioning component B110, the locking member B1161 is held in the unlocked position by the action of the first reset member B1163 (see Figure 30), and at the same time, the blocking part B11621 retracts from the locking groove B11611.

[0209] When it is necessary to install the vehicle body B200 onto the first positioning component B110, that is, when it is necessary to connect the engaging component B230 to the connecting mechanism B116, referring to Figures 29 and 30, the user can first place the engaging component B230 into the slot B11411 and make the engaging component B230 abut against the push wall B11613 of the hook slot B11612. Then, push the push wall B11613 of the hook slot B11612 downward to drive the locking component B1161 to pivot (switching from Figure 30 to Figure 29) until the locking component B1161 extends into the slot B11411 and seals the opening of the slot B11411. At the same time, after the locking member B1161 rotates, the locking groove B11611 is opposite to the blocking part B11621 of the locking retainer B1162. The second reset member B1164 drives the locking retainer B1162 to move to the locked position, so that the blocking part B11621 is locked in the locking groove B11611, and finally the locking member B1161 is kept in the locked position, realizing a stable connection with the engaging member B230.

[0210] When it is necessary to separate the vehicle body B200 from the first positioning component B110, that is, when it is necessary to disengage the locking component B230 from the connecting mechanism B116, the user can flexibly choose to operate the first unlocking component B131 or the second unlocking component B132 to release the lock according to the state of the first positioning component B110. For example, when the first positioning component B110 is in the side-facing mode, the first unlocking component B131 is easier to operate than the second unlocking component B132. Therefore, the user can pull the first unlocking component B131, which pushes the protrusion B1312 against the protrusion B11622, thereby causing the locking retainer B1162 to move from the locked position to the unlocked position (switching from Figure 29 to Figure 30). After the blocking part B11621 exits from the locking groove B11611, under the action of the first reset component B1163, the locking component B1161 can automatically pivot from the locked position to the unlocked position, so that the locking component B161 retracts from the slot B11411, the slot of the slot B11411 opens, thereby completing the unlocking action.

[0211] In one embodiment, the positioning component B100 further includes an angle adjustment mechanism (not shown in the figure). This angle adjustment mechanism is disposed in the first positioning component B110 and is used to adjust the tilt angle of the vehicle body B200 relative to the second positioning component B120. This improves the comfort of infants and toddlers riding in the vehicle body B200. Specifically, the angle adjustment mechanism is disposed between the rotating seat B113 and the connecting seat B114 to adjust the tilt angle of the connecting seat B114 relative to the rotating seat B113. Specifically, the angle adjustment mechanism includes an adjustment operating member B140 (see Figure 19), which is movably (e.g., movable) disposed in the first positioning component B110 to allow adjustment of the tilt angle between the connecting seat B114 and the rotating seat B113, thereby adjusting the angle of the vehicle body B200 mounted on the connecting seat B114 relative to the second positioning component B120. In other words, when a user needs to adjust the tilt angle of the vehicle body B200, the user can directly operate the adjustment operating member B140 to adjust the tilt angle of the vehicle body B200. Specifically, in this embodiment, the adjustment operation member B140 is disposed on the support portion B1142 and is on the same side as the second release member B132. Viewed along the extending direction of the support portion B1142, the adjustment operation member B140 can be located above or below the second release member B132, or the two can be arranged side-by-side, i.e., at the same height. It should be noted that the moving direction of the adjustment operation member B140 can be opposite to the moving direction of the second release member B132; of course, their moving directions can also be the same. Specifically, in this embodiment, the moving direction of the adjusting operation member B140 is opposite to the moving direction of the second releasing member B132. The operating direction of the second releasing member B132 is downward along the extension direction of the support portion B1142 (e.g., along the S1 direction, see Figure 19), and the operating direction of the adjusting operation member B140 is upward along the extension direction of the support portion B1142 (e.g., along the S3 direction, see Figures 18 and 19), wherein the S3 direction is parallel to and opposite to the S1 direction. In other words, in this embodiment, when the user needs to detach the vehicle body B200 from the first positioning component B110, the second releasing member B132 can be pushed downward (i.e., pressed down). In this way, the second releasing member B132 will move and drive the connecting mechanism B116 to release via the traction component B134. When the user needs to adjust the tilt angle of the vehicle body B200 on the first positioning component B110, the adjusting operation member B140 can be pushed upward (i.e., pulled up). In this way, the adjustment mechanism B140 moves to drive the related structure to adjust the tilt angle of the carrier body B200. In this embodiment, the adjustment mechanism B140 and the second release mechanism B132 operate in opposite directions. This design can effectively avoid user misoperation, thereby improving the safety and reliability of the positioning component 100 during use.

[0212] The aforementioned vehicle B1000 and positioning component B100 have at least the following technical effects:

[0213] The aforementioned vehicle B1000 includes a positioning component B100. In this positioning component B100, since the first track B121 and the second track B122 intersect in a T-shape, when the first slider B111 slides along the first track B121 and the second slider B112 slides along the second track B122, the first positioning component B100 can only switch between a rearward use mode and a lateral use mode. This design simplifies the usage modes of the first positioning component B110; for example, it does not have a forward use mode. This effectively prevents user error from causing the first positioning component B110 to switch to the forward use mode, improving the safety and reliability of the positioning component B100. Simultaneously, users can select a suitable usage mode from the rearward and lateral use modes according to different needs, thereby improving the applicability of the positioning component B100. Furthermore, since the first positioning component B110 is equipped with a release mechanism B130, the release mechanism B130 can be used to release the first positioning component B110 from locking the vehicle body B200. Specifically, the release mechanism B130 includes a first release element B131 and a second release element B132, both of which can release the first positioning component B110 from locking the vehicle body B200. Therefore, when the first positioning component B110 is in different usage modes, the user can flexibly select the appropriate and easy-to-operate first release element B131 or second release element B132 to complete the release action. This design enhances the ease of use of the positioning component B100, making it convenient for the user to release the lock and remove the vehicle body B200, thus improving the user experience.

[0214] Figure 35 shows a perspective view of a vehicle C1000 provided according to an embodiment of a third aspect of the present invention. The vehicle C1000 may include a vehicle body C200 and a positioning component C100 provided according to some embodiments of the third aspect of the present invention. The vehicle body C200 is connected to the positioning component C100, and the positioning component C100 is connected to a car seat (not shown in the figure). In other words, the vehicle body C200 can be mounted to a car seat via the positioning component C100, thereby improving the safety of children or infants riding in a car. The vehicle body C200 and the positioning component C100 will be described in conjunction with the vehicle C1000 described below.

[0215] In one embodiment, the carrier body C200 can be, for example, a baby carrier (see Figure 35), a seat (not shown), or a sleeping box (not shown) for carrying infants; or it can be a pet carrier (not shown) for carrying animals. It should be noted that the bottom of the carrier body C200, such as the baby carrier or seat, is usually provided with a locking member C230 (see Figure 52). These locking members C230 are mainly used to connect with the connection locking mechanism C160 of the positioning component C100 (see Figure 52, the specific structure is described below), thereby realizing a quick connection between the carrier body C200 and the positioning component C100.

[0216] Specifically, in this embodiment, the carrier body C200 is a baby carrier, mainly used to carry infants and toddlers weighing no more than 35 pounds or with a height no more than 87 cm. As shown in Figure 35, the carrier body C200 generally includes a seat part C210 and a backrest part C220 connected and arranged at an angle. The seat part C210 is mainly used to support the buttocks and legs of the infant and toddler, while the backrest part C220 is used to support the back and head of the infant and toddler.

[0217] Referring to Figures 35 to 37, in the first embodiment of the third aspect, the positioning component C100 may include a first positioning component C110, a second positioning component C120, and a first operating member C130. The first positioning component C110 is used for locking connection with the vehicle body C200, and the second positioning component C120 is used for connecting to the vehicle seat. Specifically, as shown in Figure 37, the first positioning component C110 has a first sliding member C111 and a second sliding member C112, and the second positioning component C120 has a first track C121 and a second track C122. The first sliding member C111 slides along the first track C121, and the second track C122 slides along the second track C122. The first operating member C130 is disposed on the first positioning component C110, and the first operating member C130 and the second sliding member C112 are disposed in opposite directions relative to the first sliding member C111.

[0218] In the aforementioned positioning component C100, since the first slider C111 slides along the first track C121 and the second slider C112 slides along the second track C122, when the first slider C111 and the second slider C112 move simultaneously, the first positioning component C110 can rotate and be displaced relative to the second positioning component C120. This allows the user to adjust the orientation of the first positioning component C110 relative to the second positioning component C120 as needed, improving the applicability of the positioning component C100. Furthermore, since the first operating member C130 and the second sliding member C112 are arranged in opposite directions relative to the first sliding member C111, i.e., the first operating member C130 and the second sliding member C112 are located on opposite sides of the first sliding member C111, the first operating member C130 is farther away from the second sliding member C112. When the user holds the first operating member C130 to rotate the first positioning component C110, due to the longer lever arm, a smaller force can generate a larger rotational torque, thus making the entire rotation operation process more effortless. This makes the rotation process of the first positioning component C110 relative to the second positioning component C120 smoother.

[0219] Referring to Figures 35 and 36, in one embodiment, the second positioning component C120 is provided with an ISOFIX connector C124A and a support leg C124B. The ISOFIX connector C124A is located approximately at the rear end of the second positioning component C120, and the support leg C124B is located approximately at the front end of the second positioning component C120. When the second positioning component C120 is mounted on a car seat, the ISOFIX connector C124A securely connects the second positioning component C120 to the car seat, and the support leg C124B rests against the vehicle's interior floor. Through the connection and support of the ISOFIX connector C124A and the support leg C124B, the second positioning component C120 can be stably installed inside the vehicle.

[0220] Referring to Figures 37 and 38, in one embodiment, the first positioning component C110 has a rotation axis. Specifically, in this embodiment, the first positioning component C110 includes a rotating seat C113, which has a receiving cavity C1131 and the aforementioned rotation axis. A first sliding member C111 is disposed on the rotating seat C113 and coaxially disposed with respect to the rotation axis, while a second sliding member C112 is disposed offset from the rotation axis. More specifically, a reinforcing member C115 is provided within the receiving cavity C1131 of the rotating seat C113. The first sliding member C111 and the second sliding member C112 are respectively fixedly mounted on the reinforcing member C115 and pass through the bottom of the rotating seat C113, so that the first sliding member C111 can slide along the first track C121 and the second sliding member C112 can slide along the second track C122.

[0221] It should be noted that in this embodiment, the rotating seat C113 is approximately circular, and the aforementioned rotation axis can be considered as the center of the circle of the rotating seat C113. Of course, in other embodiments, the rotating seat C113 can also be other symmetrical shapes (such as ellipse, rectangle, etc.), and the rotation axis can be the geometric center of the rotating seat C113 or a position off from the geometric center; or, the rotating seat C113 can also be asymmetrical, and the rotation axis can be set according to actual needs.

[0222] Referring to Figures 36 and 37, in one embodiment, the first positioning component C110 further includes a connecting seat C114 for connecting to and supporting the vehicle body C200. Specifically, the connecting seat C114 may include, for example, a connecting portion C1141 and a support portion C1142 that are connected or integrally formed. The connecting portion C1141 is connected to the rotating seat C113, and two rows of protrusions C1141A are provided on the connecting portion C1141, with a locking mechanism C160 disposed on the protrusions C1141A. The support portion C1142 extends upward at an angle relative to the connecting portion C1141, and an open mounting space C1143 is formed between the support portion C1142 and the connecting portion C1141. This mounting space C1143 is used to accommodate the seat portion C210 of the vehicle body C200 (see Figures 35 and 36). After the vehicle body C200 is connected to the connection locking mechanism C160 located on the connecting part C1141, the support part C1142 is used to support the back part C220 of the vehicle body C200 (see Figure 35). In this way, the stability of the vehicle body C200 installed on the first positioning component C110 can be improved.

[0223] It should be noted that in this embodiment, the connecting seat C114 is pivotally connected to the rotating seat C113 via the connecting part C1141. Therefore, the connecting seat C114 can pivot relative to the rotating seat C113, and during the pivoting process, the connecting seat C114 can be angularly adjusted relative to the rotating seat C113. Thus, when the carrier body C200 is installed on the connecting seat C114, the tilt angle of the carrier body C200 relative to the second positioning component C120 can be adjusted by adjusting the tilt angle of the connecting seat C114 relative to the rotating seat C113, thereby improving the comfort of infants and young children riding in the carrier body C200. Of course, in other embodiments, the connecting seat C114 can also be integrally formed with the rotating seat C113; no specific limitation is made here.

[0224] Referring again to Figures 36 and 37, in one embodiment, for the first positioning component C110, the connecting portion C1141 is generally an elongated structure that extends generally along the radial direction of the rotating seat C113, and the support portion C1142 is disposed at one end of the connecting portion C1141. Specifically, in this embodiment, the position of the support portion C1142 on the rotating seat C113 is referred to as the rear end of the first positioning component C110.

[0225] In one embodiment, the first track C121 and the second track C122 are intersected, and a cross center C123 is formed at the intersection. The intersection of the first track C121 and the second track C122 can form a T-shaped track (see Figure 37). Of course, in some other embodiments not shown, the intersection of the first track C121 and the second track C122 can also form a cross-shaped track, and this is not a limitation. It should be noted that the cross center C123 can be the geometric center of the second positioning component C120 or a position deviating from the geometric center. Specifically, in this embodiment, the cross center C123 can be the geometric center of the second positioning component C120.

[0226] The structure of the positioning component C100 is briefly explained below with reference to relevant diagrams and taking the intersection of the first track C121 and the second track C122 in a T-shape as an example.

[0227] Referring to Figure 37, in this embodiment, the first slider C111 and the second slider C112 are located on the lower surface of the first positioning component C110, that is, the first slider C111 and the second slider C112 are located on the side of the rotating seat C113 opposite to the connecting seat C114. The first slider C111 is approximately coaxially arranged with the rotation axis of the rotating seat C113 (i.e., the first slider C111 can be considered to be located at the rotation axis), and the second slider C112 is approximately located below the support portion C1142, that is, the second slider C112 can be considered to be located at the rear end of the rotating seat C113. Therefore, from an overall perspective, the first slider C111 can be considered to be located in the middle of the first positioning component C110, and the second slider C112 can be considered to be located at the rear end of the first positioning component C110 and behind the first slider C111. As described above, the first operating member C130 and the second sliding member C112 are located on opposite sides of the first sliding member C111. Therefore, in this embodiment, when the second sliding member C112 is located at the rear end of the first positioning component C110, the first operating member C130 can be considered as being located at the front end of the first positioning component C110. More specifically, the first operating member C130 is located between the two convex hulls C1141A.

[0228] Referring to Figures 37 and 39, in this embodiment, the first track C121 on the second positioning component C120 extends along either the first direction F1 or the third direction F3, and the second track C122 extends along the second direction F2. The first direction F1 and the third direction F3 are parallel and opposite, and the first direction F1 intersects the second direction F2. Specifically, the first track C121 is divided by a cross center C123 to form a connected first track segment C121A and a third track segment C121B. The first track segment C121A extends along the first direction F1, and the third track segment C121B extends along the third direction F3. Therefore, when the first positioning component C110 rotates relative to the second positioning component C120 to face away from the second direction F2, the first slider C111 is located at the cross center C123, and the second slider C112 is located on the second track C122 (see Figure 39). At this time, the second slider C112 can be considered to be located on the side of the first slider C111 along the second direction F2, and the first operating member C130 is located on the side of the first slider C111 along the second direction F2 away from the second slider C112. When the first positioning component C110 rotates relative to the second positioning component C120 to face the first direction F1, the second slider C112 is located at the intersection center C123, and the first slider C111 is located at the first track segment C121A (see Figures 40 and 41). When the first positioning component C110 rotates relative to the second positioning component C120 to face the third direction F3, the second slider C112 is located at the intersection center C123, and the first slider C111 is located at the third track segment C121B (see Figures 42 and 43).

[0229] It should be noted that the phrase "the first positioning component C110 rotates relative to the second positioning component C120 to face away from the second direction F2" means that the front end of the first positioning component C110 faces away from the second direction F2. Similarly, "the first positioning component C110 rotates relative to the second positioning component C120 to face the first direction F1" means that the front end of the first positioning component C110 faces the first direction F1. "The first positioning component C110 rotates relative to the second positioning component C120 to face the third direction F3" means that the front end of the first positioning component C110 faces the third direction F3. Considering the orientation of the positioning component C100 installed on the car seat, the first direction F1 is defined as the direction facing the left door of the car, the third direction F3 is the direction facing the right door of the car, and the second direction F2 is the direction facing the front of the car. Therefore, the aforementioned "rotation of the first positioning component C110 relative to the second positioning component C120 to face away from the second direction F2" can be considered as the front end of the first positioning component C110 facing away from the front of the car, that is, the front end of the first positioning component C110 facing the rear of the car. "Rotation of the first positioning component C110 relative to the second positioning component C120 to face the first direction F1" can be considered as the front end of the first positioning component C110 facing the right side door of the car. "Rotation of the first positioning component C110 relative to the second positioning component C120 to face the third direction F3" can be considered as the front end of the first positioning component C110 facing the left side door of the car. In this way, the user can orient the vehicle body C200 in various directions according to actual needs, aligning it with the first positioning component C110.

[0230] It should also be emphasized that, since the second track C122 extends along the second direction F2 (i.e., the direction opposite to the rear of the car), when the first slider C111 and the second slider C112 slide along the first track C121 and the second track C122 respectively, the first positioning component C110 can only rotate relative to the second positioning component C120 to face away from the second direction F2, towards the first direction F1, or towards the third direction F3. Thus, when the basket is installed on the first positioning component C110, the basket can be used facing the rear of the car and laterally. Specifically, in this embodiment, the state when the first positioning component C110 is rotated to face away from the second direction F2 is called the rearward use mode; the state when the first positioning component C110 is rotated to face the first direction F1 is called the leftward lateral use mode; the state when the first positioning component C110 is rotated to face the third direction F3 is called the rightward lateral use mode; the leftward lateral use mode and the rightward lateral use mode are collectively referred to as the lateral use mode.

[0231] As shown in Figure 37, in one embodiment, the second positioning component C120 further has a center line Y. The second positioning component C120 is symmetrical about the center line Y, which extends along the second direction F2 and is coaxially arranged with the second track C122. The first track C121 and the second track C122 form an intersection center C123, which is located on the center line Y. Thus, the first track C121 is equivalent to being divided by the center line Y to form a first track segment C121A extending along the first direction F1 and a third track segment C121B extending along the third direction F3. Specifically, in this embodiment, the center line Y can be regarded as the axis of symmetry of the second positioning component C120 along the first direction F1 or the third direction F3; in other words, the second positioning component C120 can be regarded as symmetrical about the center line Y in the left and right directions. When the first positioning component C110 is in the rearward use mode, the first slider C111 and the second slider C112 are both located on the center line Y. Therefore, when the first positioning component C110 is rotated to the lateral use mode relative to the second positioning component C120, the first positioning component C110 can extend laterally relative to the second positioning component C120 to get closer to the door.

[0232] In one embodiment, when the first positioning component C110 is in the rearward usage mode, the first operating member C130, the first sliding member C111, and the second sliding member C112 are all located on the center line Y. The first operating member C130 is located on the side of the first sliding member C111 away from the second sliding member C112, meaning the distance between the first operating member C130 and the second sliding member C112 is greater than the distance between the first operating member C130 and the first sliding member C111. This increases the rotational torque of the first positioning component C110. Furthermore, in this embodiment, the distance between the first operating member C130 and the first sliding member C111 is greater than the distance between the second sliding member C112 and the first sliding member C111. This results in a greater distance between the first operating member C130 and the second sliding member C112, meaning a longer lever arm. Applying a smaller force can generate a larger torque. Thus, when the user manipulates the first operating member C130 to rotate the first positioning component C110, the smoothness of the rotation and sliding of the first positioning component C110 can be improved, making the entire operation process more effortless.

[0233] Optionally, in some other embodiments not shown, the positions of the second slider C112 and the first operating member C130 can be interchanged. For example, when the first slider C111 is located in the middle of the first positioning component C110 and the second slider C112 is located at the front end of the first positioning component C110, the first operating member C130 can be located at the rear end of the first positioning component C110. In this case, with respect to the first track C121 on the second positioning component C120, the first track segment C121A extends along the first direction F1, the third track segment C121B extends along the third direction F3, and the second track C122 extends along the fourth direction F4. The fourth direction F4 is parallel to and opposite to the second direction F2 shown in the aforementioned embodiments. Therefore, when the first positioning component C110 rotates relative to the second positioning component C120 to face the fourth direction F4 (or away from the second direction F2), the first slider C111 is located at the intersection center C123, and the second slider C112 is located on the second track C122. At this time, the second slider C112 can be regarded as being located on one side of the first slider C111 along the fourth direction F4, and the first operating member C130 is located on the side of the first slider C111 along the fourth direction F4 away from the second slider C112.

[0234] Similarly, it should be noted that the aforementioned "first positioning component C110 rotates relative to the second positioning component C120 to face the fourth direction F4" refers to the front end of the first positioning component C110 facing the fourth direction F4. Considering the orientation of the positioning component C100 installed on the car seat, the fourth direction F4 should be towards the rear of the car. Therefore, the aforementioned "first positioning component C110 rotates relative to the second positioning component C120 to face the fourth direction F4" can be considered as the front end of the first positioning component C110 facing the rear of the car, that is, the front end of the first positioning component C110 facing away from the front of the car. Therefore, in conjunction with the aforementioned embodiments, the state of the first positioning component C110 rotating relative to the second positioning component C120 to face away from the second direction F2 shown in the aforementioned embodiments is equivalent to the state of the first positioning component C110 rotating relative to the second positioning component C120 to face the fourth direction F4 shown in this embodiment.

[0235] Referring to Figures 36, 37, 45, and 46, in one embodiment, the positioning component C100 may further include a rotation locking mechanism C140. This rotation locking mechanism C140 is disposed on one of the first positioning component C110 and the second positioning component C120, and is adapted to lock into the other of the first positioning component C110 and the second positioning component C120. Specifically, in this embodiment, the rotation locking mechanism C140 is disposed on the second positioning component C120 and is located approximately at the rear end of the second positioning component C120. When the first positioning component C110 is in a rearward use mode, the rotation locking mechanism C140 is located on the centerline Y, specifically, on the side of the first slider C111 opposite to the second slider C112 along the second direction F2. More specifically, when the first positioning component C110 is in the rearward use mode, the first operating member C130 is positioned close to the rotary locking mechanism C140. Optionally, the distance between the first operating member C130 and the first sliding member C111 is greater than the distance between the first operating member C130 and the rotary locking mechanism C140. Specifically, the first positioning component C110 is provided with a locking part C1132, which is located at the front end of the first positioning component C110 and can be a slot structure or a hole structure. Therefore, when the first positioning component C110 is in the rearward use mode, the rotary locking mechanism C140 can lock and engage with the locking part C1132 to restrict the rotation of the first positioning component C110 relative to the second positioning component C120. In other words, the rotary locking mechanism C140 can be used to lock and engage with the locking part C1132 to lock the first positioning component C110 in the rearward use mode (i.e., locked in the direction facing the rear of the vehicle). More specifically, in this embodiment, the reinforcing member C115 and the rotating seat C113 together form a locking part C1132 with a groove or hole structure. In other words, the locking part C1132 with a groove or hole structure is formed on the reinforcing member C115 and the rotating seat C113. Specifically, as shown in Figures 45 and 46, both the rotating seat C113 and the reinforcing member C115 are provided with a through hole C1152. The two through holes C1152 are arranged adjacent to each other, and the two through holes C1152 together constitute the locking part C1132, thus increasing the structural strength of the locking part C1132. Of course, in other embodiments, the through hole 1152 on the reinforcing member C115 can also be omitted, and the locking part C1132 can be formed by the through hole C1152 on the rotating seat C113. No specific limitation is made here.

[0236] Referring to Figures 45 and 46, in one embodiment, the rotary locking mechanism C140 includes a locking member C141, which is pivotally connected to the second positioning component C120 and has a locked position and an unlocked position. Of course, in other embodiments, the locking member C141 may also be slidably disposed on the second positioning component C120 to switch between the locked position and the unlocked position. Specifically, in this embodiment, the second positioning component C120 has an inner cavity C125, and a support member C142 is provided in the inner cavity C125. The locking member C141 is rotatably disposed on the support member C142 to switch between the locked position (as shown in Figure 45) and the unlocked position (as shown in Figure 46). More specifically, the second positioning component C120 has a through hole C126 communicating with the inner cavity C125. When the locking member C141 is in the locked position, at least a portion of the locking member C141 can pass through the through hole C126 and extend into the locking part C1132, thereby restricting the rotation of the first positioning component C110 relative to the second positioning component C120. When the locking member C141 is in the unlocked position, the locking member C141 can retract from the locking part C1132 and retract into the inner cavity C125 to release the locking of the locking part C1132, thereby allowing the first positioning component C110 to rotate relative to the second positioning component C120. More specifically, as shown in Figures 45 and 46, the locking member C141 may include a locking hook part C1411, a pivot part C1412, and a driving part C1413 connected in sequence, such that the locking hook part C1411 and the driving part C1413 can be regarded as being located on both sides of the pivot part C1412, respectively. The pivot part C1412 can be pivotally connected to the support part C142 through a connector (such as a pin or rivet), and the locking hook part C1411 is used to extend out of the through hole C126 to lock or plug into the locking part C1132.

[0237] It should be noted that in this embodiment, the rotary locking mechanism C140 further includes a third reset member (not shown in the figure). The third reset member can be, for example, an elastic element such as a spring, a sheet, or a torsion spring. The third reset member is used to drive the locking member C141 to automatically switch from the locked position to the unlocked position.

[0238] Referring to Figures 40, 45, and 46, in one embodiment, a protrusion C127 is formed on the upper surface of the second positioning component C120, and this protrusion C127 is located on the side of the intersection center C123 away from the second track C122 along the second direction F2. A protruding limiting protrusion C128 is formed on the protrusion C127, and this limiting protrusion C128 forms an open groove structure C129 with the upper surface of the second positioning component C120. When the first positioning component C110 is in the rearward use mode, a portion of the circumferential edge of the first positioning component C110 (i.e., the rotating seat C113) can be inserted into this groove structure C129 (compare Figures 36 and 40). Thus, the groove structure C129 can limit the approximately vertical wobbling of the front end of the first positioning component C110, while allowing the first positioning component C110 to rotate and slide in the horizontal direction (i.e., the plane containing the first direction F1 and the second direction F2). Specifically, in this embodiment, the through hole C126 on the second positioning component C120 is located within the groove structure C129. When the first positioning component C110 is in the rearward use mode, the first positioning component C110 can be restricted from disengaging from the second positioning component C120 in the vertical direction (i.e., the direction perpendicular to the plane containing the first direction F1 and the second direction F2) by having its front edge engaged within the groove structure C129. Furthermore, the locking member C141 can pass through the through hole C126 and extend into the locking part C1132 to lock the rotation and sliding of the first positioning component C110 relative to the second positioning component C120 in the horizontal direction, thereby improving the stability and security of the first positioning component C110 in the rearward use mode.

[0239] Referring to Figures 36 and 44 to 46, in this embodiment, the first operating element C130 can function as a release button. It is movably mounted on the first positioning component C110 (specifically mounted on the connecting seat C114) and can drive and cooperate with the locking element C141. Thus, by operating the first operating element C130, the locking element C141 can be switched from the locked position to the released position.

[0240] Referring to Figures 45 to 48, in one embodiment, the positioning component C100 further includes a pusher C150, which is movably disposed within the receiving cavity C1131 of the rotating seat C113. Specifically, the pusher C150 includes a first end C151 and a second end C152 connected together. The first end C151 is used to abut against the first operating member C130, and the second end C152 is used to push against the locking hook portion C1411 of the locking member C141, so that the locking hook portion C1411 of the locking member C141 can retract from the locking portion C1132. Specifically, in this embodiment, the locking portion C1132 has a through-hole structure, which communicates with the receiving cavity C1131 of the rotating seat C113. When the locking member C141 is in the locked position (see Figure 45), the locking hook portion C1411 of the locking member C141 passes through the through hole C126 and the locking part C1132 in sequence to extend into the receiving cavity C1131. At this time, the locking hook portion C1411 of the locking member C141 can contact or be spaced apart from the second end C152 of the pusher C150.

[0241] More specifically, in this embodiment, the first operating member C130 moves on the first positioning component C110 and has a first position and a second position. When the first operating member C130 moves from the first position to the second position (switching from FIG45 to FIG46), the first operating member C130 drives the pushing member C150 to move, thereby enabling the second end C152 of the pushing member C150 to push the locking hook portion C1411 of the locking member C141 to move, so that the locking hook portion C1411 of the locking member C141 retracts from the receiving cavity C1131 and the locking portion C1132.

[0242] It should be noted that in this embodiment, the first position is closer to the first sliding member C111 (or the middle of the first positioning component C110) than the second position. Therefore, when the locking mechanism C140 is released by the first operating member C130, the first operating member C130 is generally moved from the first position to the second position by pushing or pulling it outward.

[0243] Referring to Figures 44 to 46, in this embodiment, the pusher C150 is disposed below the first operating member C130. The first operating member C130 has a snap-fit ​​recess C131, and the first end C151 and the second end C152 of the pusher C150 are arranged at an angle. Specifically, the first end C151 and the second end C152 are approximately perpendicular, and the first end C151 of the pusher C150 extends into the snap-fit ​​recess C131 to abut against the first operating member C130. When the first operating member C130 moves, the first operating member C130 can drive the pusher C150 to move to release the locking member C141. It should be noted that in this embodiment, the pushing member C150 is movably disposed on the reinforcing member C115 within the rotating seat C113. When the connecting seat C114 pivots relative to the rotating seat C113 to adjust the tilt angle, the engaging recess C131 provides space for the first end C151 to move, allowing the first end C151 to be stably held within the engaging recess C131. This also prevents interference between the pushing member C150 and the connecting seat C114 when adjusting the tilt angle. Of course, in other embodiments, the first end C151 of the pushing member C150 can also be directly fixedly connected to the first operating member C130; no specific limitations are imposed here.

[0244] Referring to Figures 47 to 50, in one embodiment, the pushing member C150 is movably disposed on the reinforcing member C115 within the rotating seat C113. Thus, the reinforcing member C115 supports the movement of the pushing member C150, preventing it from vertically detaching from the first operating member C130 during movement, thus providing good support. In one embodiment, as shown in Figures 49 and 50, one of the pushing member C150 and the reinforcing member C115 is provided with a limiting groove C153, and the other is provided with a limiting rod C1151, which passes through the limiting groove C153. Specifically, in this embodiment, the pushing member C150 is provided with the limiting groove C153, and the reinforcing member C115 is provided with the limiting rod C1151. Through the guiding engagement between the limiting rod C1151 and the limiting groove C153, the pushing member C150 can be prevented from shifting during movement.

[0245] Referring to Figures 49 and 50, in one embodiment, the positioning component C100 further includes a first reset member C171. The first reset member C171 can be an elastic element such as a spring or a sheet spring. It is disposed within the accommodating cavity C1131 and acts between the pushing member C150 and the first positioning component C110 to drive the pushing member C150 to reset, allowing the locking member C141 to switch from the unlocked position to the locked position. Specifically, in this embodiment, the first reset member C171 is a tension spring, and a fixing member C1133 protrudes from the cavity wall (or reinforcing member C115) of the accommodating cavity C1131 (see Figures 45 and 46). One end of the tension spring is connected to the fixing member C1133, and the other end is connected to the pushing member C150. When the first operating member C130 moves from the first position to the second position to drive the pushing member C150 to move, the tension spring is stretched by a tension force (switching from Figure 49 to Figure 50). When the user releases the first operating element C130, i.e., when no force (such as pushing or pulling) is applied to the first operating element C130, the tension spring automatically retracts and resets, simultaneously driving the pusher element C150 to reset (switching from Figure 50 to Figure 49). During the reset process, the pusher element C150 pushes the first operating element C130 back to the first position. It should be noted that in this embodiment, the extension and retraction direction of the tension spring is parallel to the movement direction of the pusher element C150.

[0246] Referring to Figures 47 and 48, in one embodiment, the positioning component C100 may further include a second reset member C172. Similarly, the second reset member C172 may be an elastic element such as a compression spring or a spring sheet, which is disposed in the receiving cavity C1131 and acts between the first operating member C130 and the first positioning component C110, to provide an elastic restoring force to the first operating member C130, so as to drive the first operating member C130 to reset to the first position (switching from Figure 48 to Figure 47).

[0247] In this embodiment, the first operating member C130 is located approximately at the front end of the connecting portion C1141 and between the two rows of protrusions C1141A. When the first positioning component C110 is in the rearward use mode, the front end of the connecting portion C1141 is approximately opposite to the protrusion C127 and the limiting protrusion C128 (see FIG. 36). To avoid interference between the first operating member C130 and the limiting protrusion C128 during the movement of the first operating member C130 from the first position to the second position, in this embodiment, as shown in FIGS. 44 to 46, the first operating member C130 is provided with a clearance portion C132, which cooperates with the limiting protrusion C128 to allow the first operating member C130 to move to the second position.

[0248] Referring to Figures 51 and 52, in one embodiment, the aforementioned connection locking mechanism C160 may include a locking hook C161. The locking hook C161 is pivotally connected to the connecting portion C1141 and has a first locking position and a first unlocking position. When the locking hook C161 is in the first locking position, it engages with the locking member C230 of the vehicle body C200 to prevent the vehicle body C200 from disengaging from the first positioning component C110. When the locking hook C161 is in the first unlocking position, it releases its engagement with the locking member C230 of the vehicle body C200, allowing the locking member C230 of the vehicle body C200 to disengage from the first positioning component C110. Specifically, in this embodiment, the protrusion C1141A on the connecting portion C1141 is provided with a recessed groove C1141B, which communicates with the internal cavity of the protrusion C1141A. The groove C1141B is used to accommodate the engaging member C230 of the carrier body C200. More specifically, the engaging hook C161 is pivotally disposed in the internal cavity of the protrusion C1141A. When the engaging hook C161 is in the first locking position, the engaging hook C161 extends at least partially into the groove C1141B to seal the opening of the groove C1141B (compare Figures 51 and 52). In this way, the engaging member C230 can be confined within the groove C1141B to achieve a locking engagement between the engaging hook C161 and the engaging member C230. When the locking hook C161 is in the first unlocked position, the locking hook C161 retracts from the slot C1141B, and the opening of the slot C1141B is open (see Figure 51). In this way, the locking component C230 can disengage from the opening of the slot C1141B.

[0249] Referring again to Figures 51 and 52, in one embodiment, the locking mechanism C160 further includes a fourth reset member C163, which may be an elastic element such as a spring, torsion spring, or sheet, and is used to abut against the locking hook C161 to keep the locking hook C161 in the first unlocked position.

[0250] Referring to Figures 47, 48, 51, and 52, in one embodiment, the first operating element C130 can also be driven to cooperate with the locking hook C161. Specifically, when the first operating element C130 is in the first position, the locking hook C161 is in the first locked position. When the first operating element C130 is in the second position, the locking hook C161 is in the first unlocked position. Thus, when the user operates the first operating element C130 to move it from the first position to the second position, the locking hook C161 can be switched from the first locked position to the first unlocked position.

[0251] Referring to Figures 47, 48, 51, and 52, in one embodiment, the locking mechanism C160 may further include a locking retainer C162, which engages with the first operating member C130. Specifically, the locking retainer C162 is movably disposed in the receiving cavity C1131 of the rotating seat C113 and has a second locking position and a second unlocking position. When the locking retainer C162 is in the second locking position, it restricts the pivoting of the engaging hook C161, keeping the engaging hook C161 in the first locking position. When the locking retainer C162 is in the second unlocking position, it separates from the engaging hook C161. When the locking retainer C162 separates from the engaging hook C161, the engaging hook C161 automatically pivots to the first unlocking position under the reset force of the fourth reset member. Therefore, in this embodiment, the user can control the position of the locking retainer C162 by operating the first operating member C130, and thus control the position of the locking hook C161.

[0252] Referring to Figures 51 and 52, in one embodiment, one of the engaging hook C161 and the locking retainer C162 has a locking groove C1611, and the other has a blocking portion C1621. Specifically, in this embodiment, the engaging hook C161 has a locking groove C1611, and the locking retainer C162 has a blocking portion C1621. When the locking retainer C162 is in the second locked position, the blocking portion C1621 engages with the locking groove C1611 (see Figure 52) to lock the engaging hook C161 in the first locked position, thus making the connecting locking mechanism C160 appear to be in a locked state. When the locking retainer C162 is in the second unlocked position, the blocking portion C1621 separates from the locking groove C1611 (see Figure 51), thus allowing the engaging hook C161 to switch between the first locked position and the first unlocked position, at which time the connecting locking mechanism C160 can be considered to be in an unlocked state.

[0253] In this embodiment, the moving directions of the first operating member C130 and the locking retainer C162 are parallel. Specifically, the first operating member C130 has a pushing protrusion C133 (see FIG. 44), and the locking retainer C162 has a pushing protrusion C1622 (see FIG. 49 and FIG. 50), with the pushing protrusion C133 abutting against the pushing protrusion C1622. Therefore, when the first operating member C130 is operated and moves from the first position to the second position, the pushing protrusion C133 can drive the pushing protrusion C1622 to move, thereby causing the locking retainer C162 to move from the second locked position to the second unlocked position (switching from FIG. 47 to FIG. 48). Of course, in other embodiments, one of the first operating member C130 and the locking retainer C162 may also have a pushing protrusion C1622, and the other may have a pushing recess (not shown in the figures), with the pushing protrusion C1622 movably inserted into the pushing recess. When the first operating member C130 is operated, it engages with the pushing protrusion C1622 through the side wall of the pushing recess, thereby causing the locking retainer C162 to switch from the second locked position to the second unlocked position. The pushing recess can be approximately a waist-shaped hole structure, and the length direction of the waist-shaped hole is parallel to the moving direction of the first operating member C130.

[0254] Referring to Figures 47 and 48, in one embodiment, the positioning component C100 further includes a fifth reset member C173, which may be, for example, an elastic element such as a spring or sheet, for abutting or connecting with the locking retainer C162 to give the locking retainer C162 a constant tendency to move toward the second locking position.

[0255] As described above, in this embodiment, the first operating element C130 can simultaneously engage with both the rotary locking mechanism C140 and the connecting locking mechanism C160. Therefore, when the user operates the first operating element C130, both the rotary locking mechanism C140 and the connecting locking mechanism C160 can be unlocked simultaneously. The following section, with reference to relevant figures, briefly explains the usage of the positioning component C100.

[0256] Referring to Figures 36 and 45, in this embodiment, when the first positioning component C110 rotates to the rearward use mode relative to the second positioning component C120, the rotation locking mechanism C140 is in a locked state, and the locking hook portion C1411 of the locking member C141 passes through the through hole C126 and the locking portion C1132 in sequence to extend into the receiving cavity C1131 of the rotating seat C113.

[0257] Referring to Figures 36, 40, and 42, when a user needs to install the vehicle body C200 onto the first positioning component C110, the user can hold the vehicle body C200 with one hand and operate the first operating component C130 with the other hand. Specifically, the user can pull the first operating component C130 outward with their index and middle fingers. When the first operating component C130 moves to the second position, it pushes the member C150 to disengage the locking hook portion C1411 of the locking member C141 from the locking portion C1132. At this time, the first positioning component C110 can rotate relative to the second positioning component C120. Specifically, after the first operating component C130 moves to the second position, the user can directly pull the first operating component C130 and apply a force to the left (along the first direction F1) or the right (along the third direction F3), thereby causing the first positioning component C110 to rotate clockwise or counterclockwise relative to the second positioning component C120 to the first direction F1 (see Figure 40) or the third direction F3 (see Figure 42). Since the first operating component C130 is located at the front end of the first positioning component C110, and the first operating component C130 and the second sliding component C112 are positioned in opposite directions relative to the first sliding component C111, and the first operating component C130 is farther away from the second sliding component C112, resulting in a longer lever arm, the user can pull and hold the first operating component C130 to rotate the first positioning component C110 with less effort. In this process, the user can release the first operating component C130 by pulling it with one hand, simultaneously rotating and sliding the first positioning component C110, making the operation more convenient.

[0258] In this embodiment, during the rotation of the first positioning component C110, the first operating member C130 remains in the second position under the action of the operation. As described above, when the first operating member C130 is in the second position, under the transmission action of the locking retainer C162, the engaging hook C161 can be in the first unlocked position, and the slot of the slot C1141B is in an open state. Therefore, during the rotation of the first positioning component C110 towards the first direction F1 or the third direction F3, the slot of the slot C1141B remains in an open state. Therefore, when the first positioning component C110 rotates to the side (i.e., the first direction F1 or the third direction F3) (i.e., in the side use mode), the user can directly place the engaging member C230 of the carrier body 200 into the slot C1141B. After placement, the first operating member C130 is directly released to reset the first operating member C130 to the first position.

[0259] It should be noted that, in this embodiment, since the first track C121 and the second track C122 are arranged in a T-shape, and the first slider C111 slides along the first track C121 and the second slider C112 slides along the second track C122, when the first positioning component C110 is rotated to the side-facing mode relative to the second positioning component C120, the front end of the first positioning component C110 extends laterally relative to the second positioning component C120 to be closer to the vehicle door (see Figures 40 and 42). This makes it easier for the user to install the vehicle body C200. Furthermore, since the first operating component C130 extends along with the front end of the first positioning component C110, the first operating component C130 also moves closer to the vehicle door, making it more convenient to operate.

[0260] It should be noted that during the insertion of the engaging component C230 of the vehicle body C200 into the slot C1141B, the engaging component C230 pushes against the engaging hook C161, causing the engaging hook C161 to pivot to the first locking position. When the engaging hook C161 pivots to the first locking position, the locking retainer C162, under the elastic force of the fifth reset component C173, can automatically reset to the second locking position, thereby locking the engaging hook C161 in the first locking position. In this way, the engaging hook C161 can stably lock the engaging component C230 onto the first positioning component C110.

[0261] It should also be noted that, in this embodiment, since the rotating seat C113 is approximately circular, during the rotation of the first positioning component C110 relative to the second positioning component C120 from the direction of the first direction F1 or the third direction F3 to the direction away from the second direction F2, the outer edge of the rotating seat C113 can contact and gradually push against the locking hook portion C1411 of the locking member C141, so that the locking hook portion C1411 of the locking member C141 retracts into the through hole C126. When the first positioning component C110 rotates to the direction away from the second direction F2, the locking hook portion C1411 of the locking member C141 faces the locking part C1132, and the locking member C141 automatically resets to the locked position under the action of the third reset member so that the locking hook portion C1411 is inserted into the locking part C1132.

[0262] In this embodiment, when the vehicle body C200 is installed on the first positioning component C110 and the first positioning component C110 is in the rearward use mode, if the user needs to remove the vehicle body C200 from the first positioning component C110, he / she can operate the first operating component C130 with one hand to simultaneously release the locking component C141 and the locking hook C161, and then pull the first operating component C130 to drive the first positioning component C110 to rotate to the side, and finally the vehicle body C200 can be directly removed.

[0263] As described above, in this embodiment, operating the first operating component C130 can simultaneously control the locking and unlocking of the rotary locking mechanism C140 and the connecting locking mechanism C160. In other words, the unlocking components of the rotary locking mechanism C140 and the connecting locking mechanism C160 are integrated into one unit. Therefore, when the user needs to install the vehicle body C200 onto the first positioning component C110, the user only needs to operate the first operating component C130 and pull the first positioning component C110 to rotate. This greatly simplifies the installation process of the vehicle body C200 and makes the entire operation more convenient. This effectively improves the user experience. Furthermore, since the unlocking components of the rotary locking mechanism C140 and the connecting locking mechanism C160 are integrated, the operation buttons on the first positioning component C110 are simplified, allowing the user to operate directly and avoiding situations such as accidental button operation.

[0264] Furthermore, in this embodiment, the first operating component C130 makes the installation and removal of the vehicle body C200 more convenient, allowing rotation-to-unlock, rotation and sliding, and disassembly-to-unlock to be completed in one step. That is, the user can operate the first operating component C130 to simultaneously release the locking component C141 and the latching hook C161, while simultaneously rotating the first positioning component C110 to extend laterally and at least partially towards one side of the vehicle door, bringing it closer to the user and making it easier for the user to install or remove the vehicle body C200. This avoids the vehicle door and roof obstructing or colliding with the installation and removal of the vehicle body C200.

[0265] Referring to Figures 36, 37, 45, and 46, in one embodiment, the positioning component C100 may further include a rotary release member C191. This rotary release member C191 is movably disposed on the second positioning component C120 and drives a rotary locking mechanism C140 to release the rotary locking mechanism C140 from locking the first positioning component C110. Specifically, in this embodiment, the rotary release member C191 is movably disposed at the front end of the second positioning component C120 (i.e., near the support leg C124B) and drives a locking member C141. Specifically, the rotary unlocking member C191 can be connected to the drive portion C1413 of the locking member C141 via a traction member (not shown in the figure), for example. When the rotary unlocking member C191 is operated (e.g., pushed or pulled), the rotary unlocking member C191 can drive the drive portion C1413 to rotate around the pivot portion C1412 via the traction member, so that the locking hook portion C1411 rotates around the pivot portion C1412 at the same time, ultimately driving the locking member C141 to move from the locked position to the unlocked position. In this way, the user can flexibly unlock the locking member C141 by selecting to operate the first operating member C130 or the rotary unlocking member C191. For example, when the vehicle body C200 is mounted on the first positioning component C110 and the first positioning component C110 is in the rear-facing use mode, if the user needs to remove the vehicle body C200 from the first positioning component C110, the operating space of the first operating component C130 is relatively small because it is located between the vehicle body C200 and the car seat back (or the second positioning component C120). Meanwhile, the rotating release component C191 is facing away from the vehicle body C200 and is not obstructed by the vehicle body C200 and remains exposed. Therefore, the user can preferentially operate the rotating release component C191 with one hand to release the locking component C141. After the locking component C141 is in the unlocked position, the user can then rotate the first positioning component C110 to the side (first direction F1 or third direction F3) with the other hand, and then operate the first operating component C130 to put the locking hook C161 in the first unlocked position. This allows the vehicle body C200 to be easily removed.

[0266] Figure 53 shows a perspective view of a positioning component C100 provided according to a second embodiment of the third aspect of the present invention, and Figure 54 shows an exploded view of a portion of the structure of the positioning component C100 provided in the second embodiment of the third aspect. This positioning component C100 is similar to the first embodiment of the third aspect described above, including components such as a first positioning component C110 and a second positioning component C120. The positioning component C100 of this embodiment is a variation of the positioning component C100 of the first embodiment of the third aspect described above. Unless otherwise specified, the structure of the components and the connection relationships between the components in this embodiment can be referred to the description in the first embodiment of the third aspect described above. The following mainly describes the differences between this embodiment and the first embodiment of the third aspect described above.

[0267] As shown in Figures 53 and 54, in the second embodiment of the third aspect, the positioning component C100 includes a second operating member C181 and a third operating member C182. The second operating member C181 is movably disposed on the first positioning component C110 and is used to drive and cooperate with the connecting locking mechanism C160 to release the locking mechanism C160 from locking the carrier body C200. The third operating member C182 is movably disposed on the first positioning component C110 and can switch between a first position and a second position. The third operating member C182 is used to drive and cooperate with the rotary locking mechanism C140 to release the rotary locking mechanism C140 from locking the first positioning component C110. In other words, in this embodiment, the third operating element C182 is used to control the release of the rotary locking mechanism C140, and the second operating element C181 is used to control the release of the connecting locking mechanism C160. That is, the third operating element C182 controls the release of the rotary locking mechanism C140, but does not control the release of the connecting locking mechanism C160. Therefore, the user can change the position of the locking element C141 by operating the third operating element C182, and change the position of the engaging hook C161 by operating the second operating element C181. It should be noted that in this embodiment, the second operating element C181 drives and cooperates with the locking retaining element C162, and the driving and connection relationship between the second operating element C181 and the locking retaining element C162 can be roughly referred to the driving and connection relationship between the first operating element C130 and the locking retaining element C162 in the first embodiment of the third aspect. Similarly, the driving principle between the third operating element C182 and the pushing element C150 in this embodiment can also be roughly referred to the driving principle between the first operating element C130 and the pushing element C150 in the first embodiment of the third aspect.

[0268] Referring to Figures 54 to 56, in this embodiment, the third operating member C182 is provided with a pushing protrusion C1821, which is used to abut against the first end C151 of the pushing member C150. When the third operating member C182 moves from the first position to the second position, the third operating member C182 drives the pushing member C150 to move, so that the second end C152 of the pushing member C150 abuts against the locking hook portion C1411 of the locking member C141, thereby causing the locking hook portion C1411 of the locking member C141 to retract from the locking portion C1132. Of course, in other embodiments, the third operating member C182 may omit the pushing protrusion C1821 and, like the first embodiment of the third aspect, be provided with a locking recess C131 (see Figure 44), and the first end C151 of the pushing member C150 is inserted into the locking recess C131 to achieve abutment between the pushing member C150 and the third operating member C182.

[0269] Referring to Figure 54, in one embodiment, the first positioning component C110 is provided with a strip-shaped guide groove C116, and the third operating component C182 is provided with a guide protrusion C1822. The guide protrusion C1822 is movably inserted into the guide groove C116 so that the third operating component C182 can reciprocate along the extension direction of the guide groove C116. Specifically, when the guide protrusion C1822 moves to both ends of the guide groove C116, the third operating component C182 is respectively in the first position and the second position.

[0270] In one embodiment, both the third operating member C182 and the second operating member C181 can be located on the rotating base C113 or on the connecting base C114, without specific limitations. In one embodiment, the third operating member C182 can be arranged side by side with the second operating member C181 in the left-right direction; of course, they can also be spaced apart in the front-back direction. Specifically, in this embodiment, the third operating member C182 and the second operating member C181 are generally located at the front end of the first positioning component C110. The third operating member C182 is arranged opposite the second operating member C181 along the same straight line. For example, when the first positioning component C110 is in the rearward use mode, the third operating member C182 and the second operating member C181 are arranged opposite each other along the second direction F2 or the fourth direction F4. More specifically, the second operating member C181 is closer to the outer edge of the first positioning component C110 than the third operating member C182. In this way, even when the vehicle body C200 is mounted on the first positioning component C110, the second operating component C181 can still be exposed relative to the third operating component C182 and is not obstructed by the seat part C210 of the vehicle body C200.

[0271] In this embodiment, when the first positioning component C110 rotates from the rearward use mode to the side use mode, both the third operating component C182 and the second operating component C181 extend relative to the second positioning component C120 along with the front end of the first positioning component C110 to get closer to the vehicle door. Since the second operating component C181 is closer to the outer edge of the first positioning component C110 and remains exposed, when the first positioning component C110 is in the side use mode, the second operating component C181 extends outward along with the first positioning component C110 and gets closer to the user standing at the vehicle door. This makes it convenient for the user to operate the second operating component C181 to release the locking mechanism C160 and remove the vehicle body C200.

[0272] In this embodiment, the positioning component C100 may also include a rotary release component C191 (see Figure 37). The location and working principle of the rotary release component C191 can be found in the first embodiment of the third aspect. The user can flexibly release the rotary locking mechanism C140 by selecting to operate the third operating component C182 or the rotary release component C191 (see below for details).

[0273] In this embodiment, the positioning assembly C100 may further include a release member C192 (see Figures 55 and 56), which is movably disposed on the side of the support C1142 facing away from the mounting space C1143. This release member C192 is adapted to engage with the connecting locking mechanism C160 to release the locking mechanism C160 from the carrier body C200. Specifically, the release member C192 may be driven to connect with the locking retainer C162, for example, via a traction member (not shown). When the release member C192 is operated (e.g., pushed or pulled), it drives the locking retainer C162 to move from a second locked position to a second unlocked position, thereby moving the engaging hook C161 from a first locked position to a first unlocked position, allowing the carrier body C200 to be removed from the first positioning assembly C110. Thus, the user can flexibly release the locking retainer C162 (or the locking hook C161) by choosing to operate the second operating component C181 or remove the release component C192. In this embodiment, when the first positioning component C110 is in the rear-facing use mode, the second operating component C181 is located between the car seat back (or the second positioning component C110) of the vehicle body C200, resulting in a small operating space for the second operating component C181, making it difficult to operate. In this embodiment, the removal and release component C192 is located on the side of the support C1142 facing away from the mounting space C1143, and it is exposed relative to the vehicle body C200 (see Figure 35). Therefore, when the first positioning component C110 is in the rear-facing use mode, the removal and release component C192 is easier to operate than the second operating component C181 to release the first positioning component C110 from locking the vehicle body C200. When the first positioning component C110 is in the lateral use mode, the second operating component C181 extends laterally closer to the user as the front end of the first positioning component C110 extends laterally, while the release component C192 is moved away from and away from the user. In this situation, the second operating component C181 is easier to operate than the release component C192 to release the first positioning component C110 from the vehicle body C200. Therefore, in this application, the user can flexibly choose to operate the second operating component C181 or the release component C192 to release the locking mechanism C160, depending on the state of the first positioning component C110.

[0274] The operation process of the positioning component C100 is briefly described below.

[0275] When the vehicle body C200 is not installed on the first positioning component C110, and the user needs to install the vehicle body C200 onto the first positioning component C110, if the first positioning component C110 is in the rear-facing use mode, the user can operate the third operating component C182 with one hand to release the rotation locking mechanism C140 from locking the first positioning component C110. At the same time, pull the third operating component C182 to rotate and slide the first positioning component C110 to the side-facing use mode. At this time, the first positioning component C110 is closer to the user on the side of the door, making it convenient for the user to directly insert the engaging component C230 of the vehicle body C200 into the slot C1141B to lock and engage with the engaging hook C161. Finally, rotate the first positioning component C110 until it is in the rear-facing use mode.

[0276] It should be noted that since the carrier body C200 is not mounted on the first positioning component C110, the third operating component C182 is not obstructed and is exposed for operation. The user can release the rotating locking mechanism C140 by operating the third operating component C182, and simultaneously pull the third operating component C182 to rotate the first positioning component C110 to the side. This process can be completed with one hand, making operation more convenient. Furthermore, since the third operating component C182 and the second sliding component C112 are arranged in opposite directions relative to the first sliding component C111, the lever arm is longer when pulling the third operating component C182 to rotate the first positioning component C110. Therefore, pulling the third operating component C182 makes it easier to rotate and slide the first positioning component C110, requiring less effort.

[0277] Optionally, the user can also selectively use one hand to operate the rotating release component C191 to release the rotating locking mechanism C140. After the rotating locking mechanism C140 is released, the user needs to use the other hand to rotate the first positioning component C110 to the side. Then, the engaging component C230 of the vehicle body C200 is placed into the slot C1141B to lock and engage with the engaging hook C161. This application is not limited to this.

[0278] When the vehicle body C200 is mounted on the first positioning component C110, and the user needs to remove the vehicle body C200 from the first positioning component C110, if the first positioning component C110 is in the rear-facing use mode, the third operating member C182 is located between the vehicle body C200's seat back and is obstructed by the seat portion C210 of the vehicle body C200, making the operating space for the third operating member C182 small and difficult to operate. Therefore, the user can first flexibly use one hand to operate the rotating release member C191 to release the locking member C141. After the locking member C141 is in the released position, the user can use the other hand to rotate the first positioning component C110 to the side (first direction F1 or third direction F3). As described above, since the second operating member C181 is closer to the front end of the first positioning component C110 than the third operating member C182, and is not obstructed by the seat portion C210 of the vehicle body C200, when the first positioning component C110 rotates to the side, the second operating member C181 also rotates to the side and protrudes from the second positioning component C120 and remains exposed. Therefore, the user can easily operate the second operating member C181 to put the locking hook C161 in the first unlocked position. In this way, the vehicle body C200 can be easily removed. Of course, in other embodiments, the user can also release the locking member C141 by operating the third operating member C182, so that the first positioning component C110 can be allowed to rotate to the side.

[0279] Of course, in other embodiments, it is not necessary to rotate the first positioning component C110 to the lateral rearward release locking mechanism C160. In other words, the locking mechanism C160 can be released directly while the first positioning component C110 is in the rearward use mode. Specifically, as described above, when the first positioning component C110 is in the rearward use mode, the user can directly release the locking retainer C162 (or the locking hook C161) by operating the disassembly release component C192, thereby allowing the vehicle body C200 to be directly removed from the first positioning component C110 without rotating the first positioning component C110.

[0280] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0281] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
