Description

Positioning components, base, and carrier Technical Field

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

[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 the safety of children while traveling. This seat generally consists of a base and a carrier body, with the carrier body detachably mounted to the base. This allows users to remove the carrier body from the base for easy transport. However, currently common bases do not have a rotating function. This limitation not only makes the installation and removal of the carrier body difficult but also increases the risk of the user's or child's head hitting the door frame during this process, thus reducing safety and convenience during use.

[0003] In addition, to ensure that the child safety seat is stably installed on the car seat, it will be pushed back to allow it to press against the back of the car seat. However, this process may scratch or damage the surface of the car seat. This is especially true for some child safety seats with fastening devices, such as ISOFIX components, which require pulling the fastening device back to allow it to engage with the locking points on the car seat. This process may also scratch or damage the surface of the car seat. Summary of the Invention

[0097] Specifically, in this embodiment, the carrier body A200 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 Figures 1 and 2, the carrier body A200 generally includes a seat part A210 and a backrest part A220 connected and arranged at an angle. The seat part A210 is used to support the buttocks and legs of the infant and toddler, and the backrest part A220 is used to support the back and head of the infant and toddler.

[0098] Referring to Figures 1 to 4, in one embodiment, the positioning component A100 may include, for example, 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. The first positioning component A110 is mounted on the second positioning component A120 and is rotatable relative to the second positioning component A120. This allows the vehicle body A200 to rotate with the first positioning component A110 relative to the second positioning component A120 for use in different orientations.

[0099] Referring to Figures 1 to 3, in one embodiment, the positioning component A100 may further include a connecting mechanism A180, which is disposed on the first positioning component A110 for connecting the vehicle body A200 (the connection principle is explained below). In other words, the vehicle body A200 can be installed onto the first positioning component A110 via the connecting mechanism A180; or, the first positioning component A110 can be connected to the vehicle body A200 via the connecting mechanism A180. Referring to Figures 1 and 5, when the vehicle body A200 is installed onto the first positioning component A110, the end of the first positioning component A110 near the backrest portion A220 of the vehicle body A200 is considered its rear end, and the end of the first positioning component A110 away from the backrest portion A220 of the vehicle body A200 is considered its front end. Specifically, 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.

[0100] Referring to Figures 3 to 5, in one embodiment, the second positioning component A120 includes a base A121, wherein the base A121 includes a support portion A1211 and an abutment portion A1212 that are connected or integrally formed. The abutment portion A1212 extends upwardly at an angle relative to the support portion A1211, forming an open mounting space between the abutment portion A1212 and the support portion A1211, in which the first positioning component A110 is installed. When the second positioning component A120 is placed on a car seat, the abutment portion A1212 abuts against the backrest of the car seat. Specifically, in this embodiment, the position of the abutment portion A1212 on the support portion A1211 is considered as the rear end of the second positioning component A120.

[0101] Please refer to Figures 3 to 5. In one embodiment, the second positioning component A120 is provided with a clamping mechanism A123, an ISOFIX connector A124A, and a support leg A124B. The clamping mechanism A123 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. In this embodiment, the ISOFIX connector A124A is connected to the bottom of the second positioning component A120 and has an unfolded state (not shown in the figures) and a retracted state (see Figure 4). When the second positioning component A120 is placed on a car seat and the ISOFIX connector A124A is in the unfolded state, the ISOFIX connector A124A is used to securely connect the second positioning component A120 to the car seat, and the support leg A124B is used to abut against the floor inside the vehicle. When the ISOFIX connector A124A is in the retracted state, it is stored and concealed at the bottom of the second positioning assembly A120, approximately located in the middle or rear-middle part of the second positioning assembly A120. Through the connection and support of the ISOFIX connector A124A and the support leg A124B, the second positioning assembly A120 can be stably installed inside the vehicle. Furthermore, in this embodiment, an ISOFIX connector A124A is provided on both the left and right sides of the second positioning component A120. One of the ISOFIX connectors A124A is provided with a webbing (not shown in the figure). The second positioning component A120 is provided with two webbing through holes A1213 (see Figure 3). The two webbing through holes A1213 are located on the left and right sides of the second positioning component A120, respectively. The webbing extends out from one ISOFIX connector A124A and passes through the webbing through hole A1213 on the corresponding side. Then it passes through the clamping mechanism A123 (see the following for the specific principle) and extends into the webbing through hole A1213 on the other side, and connects to the ISOFIX connector A124A on the other side.

[0102] Referring again to Figures 3 to 5, in one embodiment, the support leg A124B includes a first support segment A1241 and a second support segment A1242. The first support segment A1241 and the second support segment A1242 are slidably connected. The end of the first support segment A1241 away from the second support segment A1242 is connected to the second positioning component A120, and the end of the second support segment A1242 away from the first support segment A1241 is used to abut against the floor inside the vehicle. By sliding between the first support segment A1241 and the second support segment A1242, the total length of the support leg A124B can be adjusted, thereby enabling the positioning component A100 to be adapted to various types of vehicles. Of course, in other embodiments, the first support segment A1241 may also be fixedly connected to the second support segment A1242; no specific limitation is made here.

[0103] In one embodiment, the support leg A124B is pivotally connected to the front end of the second positioning component A120 and has a first mode (see Figures 3 and 4) and a second mode (not shown in the figures). Specifically, the bottom of the second positioning component A120 is provided with a storage groove A1216 (see Figures 4 and 6). When the support leg A124B is in the first mode, the support leg A124B is unfolded relative to the second positioning component A120 and is set at an angle to the second positioning component A120, allowing the support leg A124B to rest against the floor inside the vehicle. When the support leg A124B is in the second mode, the support leg A124B is folded relative to the second positioning component A120 and stored in the storage groove A1216. This reduces the volume of the positioning component A100, making it convenient for the user to store or transport the positioning component A100 when it is not needed.

[0104] Referring to Figures 5 to 7, in this embodiment, the abutment portion A1212 of the second positioning component A120 is provided with a receiving groove A1214. The shape of the receiving groove A1214 is approximately adapted to the shape of the clamping mechanism A123 and is a strip-shaped structure, with its extension direction being the same as the extension direction of the abutment portion A1212. Specifically, the clamping mechanism A123 includes a clamping body A1231, which is a strip-shaped structure. Its bottom end is pivotally connected to the bottom end of the receiving groove A1214, thus allowing the clamping body A1231 to have an open state (see Figure 5) and a closed state (see Figure 3). When the clamp body A1231 pivots relative to the bottom end of the receiving groove A1214 to open, the clamp body A1231 retracts from the receiving groove A1214, exposing the receiving groove A1214. At this time, the webbing passing through the webbing perforation A1213 on one side can be threaded onto the side of the clamp body A1231 facing the receiving groove A1214. When the clamp body A1231 pivots relative to the bottom of the receiving groove A1214 to close, the clamp body A1231 re-enters the receiving groove A1214. During this process, the clamp body A1231 can press the webbing against the receiving groove A1214 to stably hold the webbing and prevent the webbing from being moved or pulled.

[0105] Referring to Figures 5 to 7, in this embodiment, the top end of the receiving groove A1214 is provided with a locking portion A12141, and the clamping mechanism A123 further includes a locking member A1232, which is movably disposed at the top end of the clamping body A1231 and adapted to engage with the locking portion A12141. When the locking member A1232 engages with the locking portion A12141, the clamping body A1231 remains in the retracted state; when the locking member A1232 disengages from the locking portion A12141, the clamping body A1231 can switch from the retracted state to the open state. Specifically, the locking member A1232 is pivotally connected to the clamping body A1231. The clamping mechanism A123 also includes a first pivot member A1233, and the locking member A1232 can pivot relative to the clamping body A1231 around the first pivot member A1233. More specifically, the locking member A1232 has a locking portion A12321 and a release operation portion A12322, wherein the locking portion A12321 is adapted to engage with the locking portion A12141, and the release operation portion A12322 is adapted to be operated to drive the locking portion A12321 to pivot about the first pivot member A1233, thereby releasing the engagement of the locking portion A12141 with the locking portion A12321. In some embodiments, the first pivot member A1233 passes through the pivot hole of the locking member A1232 and the pivot hole of the clamp body A1231, and the locking member A1232 is pivotable about the first pivot member A12323 relative to the clamp body A1231. In some embodiments, the locking member A1232 has the first pivot member A1233 and is pivotally connected to the clamp body A1231 through the first pivot member A1233.

[0106] Referring to Figure 8, in one embodiment, the second positioning component A120 further includes an adjustment seat A125, which is pivotally connected to the bottom of the base A121. Specifically, the adjustment seat A125 is pivotally connected to the bottom of the support portion A1211 of the base A121. When the second positioning component A120 is placed on a car seat, the adjustment seat A125 can be supported by the car seat. The positioning component A100 may also include an angle adjustment mechanism A130, which is disposed between the base A121 and the adjustment seat A125, for adjusting the tilt angle of the base A121 relative to the adjustment seat A125. Thus, when the vehicle body A200 is mounted on the first positioning component A110, the angle between the base A121 and the adjustment seat A125 can be adjusted by the angle adjustment mechanism A130, thereby adjusting the tilt angle of the vehicle body A200 relative to the second positioning component A120 to improve the comfort of infants and young children sitting in the vehicle body A200.

[0107] Referring to Figures 6 to 9, specifically, the angle adjustment mechanism A130 includes a locking portion A131 and a locking member A132. The locking portion A131 is disposed on the adjusting base A125, and the locking member A132 is pivotally connected to the base A121. The locking member A132 can engage with the locking portion A131 (see Figure 6) or disengage (see Figure 9). When the locking member A132 engages with the locking portion A131, the included angle between the base A121 and the adjusting base A125 remains fixed. When the locking member A132 disengages from the locking portion A131, the included angle between the base A121 and the adjusting base A125 becomes adjustable. Specifically, the locking portion A131 is a plurality of groove structures or a plurality of hole structures formed on the side wall of the adjusting base A125. More specifically, multiple slot structures or multiple hole structures are arranged in an arc shape roughly in the vertical direction around the pivot point of the base A121 and the adjusting seat A125. When the engaging member A132 engages with the top slot structure or hole structure, the included angle between the base A121 and the adjusting seat A125 is greater than the included angle between the base A121 and the adjusting seat A125 when the engaging member A132 engages with the bottom slot structure or hole structure.

[0108] Referring again to Figures 6 to 9, in one embodiment, the angle adjustment mechanism A130 further includes an angle adjustment operating member A133 and a second traction member A134. The angle adjustment operating member A133 is operably disposed on the base A121, and the second traction member A134 connects the angle adjustment operating member A133 and the engaging member A132. When the angle adjustment operating member A133 is operated, the angle adjustment operating member A133 drives the engaging member A132 to pivot via the second traction member A134 to disengage from the engaging portion A131. Specifically, the engaging member A132 includes a second connecting portion A1321, a second pivoting portion A1322, and an engaging portion A1323. The engaging member A132 is pivotally connected to the base A121 via the second pivoting portion A1322. The second connecting portion A1321 is used to engage with the second traction member A134, and the engaging portion A1323 is adapted to engage with the engaging portion A131. More specifically, the angle adjustment operation member A133 is movably disposed on the abutment portion A1212 of the base A121, and the abutment portion A1212 is provided with a guide portion A1215 inside, and the second traction member A134 passes through the guide portion A1215 and is connected to the second connecting portion A1321 of the angle adjustment operation member A133 and the engaging member A132.

[0109] Referring to Figure 8, in one embodiment, the angle adjustment mechanism A130 further includes a second reset member A135. The second reset member A135 can be, for example, an elastic element such as a spring or a sheet. The second reset member A135 abuts between the base A121 and the adjusting seat A125 and is used to drive the adjusting seat A125 to pivot in a direction away from the base A121. In this way, when the engaging member A132 disengages from the engaging part A131, the angle between the adjusting seat A125 and the base A121 can be automatically increased under the action of the second reset member A135, without the user having to manually pull out the adjusting seat A125. While operating the angle adjustment operating member A133, the user can lift or press down the base A121 to control the rotation range of the adjusting seat A125 relative to the base A121.

[0110] Referring to Figures 6 and 9, in one embodiment, the angle adjustment mechanism A130 further includes a fifth reset member A136, which may be an elastic element such as a spring or a sheet. Specifically, the fifth reset member A136 is a tension spring, which drives the engaging member A132 to automatically engage with the engaging part A131. When the user operates (e.g., pushes or pulls) the angle adjustment operating member A133, the angle adjustment operating member A133 moves to drive the second traction member A134 to move. The second traction member A134 drives the engaging member A132 to rotate around the second pivot part A1322 so that the engaging part A1323 is disengaged from the engaging part A131. At this time, the fifth reset member A136 is stretched (see Figure 9). When the user releases (or does not operate) the angle adjustment operation component A133, the fifth reset component A136 resets and drives the engaging component A132 to pivot (switching from Figure 9 to Figure 6), so that the engaging part A1323 automatically engages with the engaging part A131 to lock the tilt angle of the base A121 relative to the adjustment seat A125.

[0111] Please refer again to Figures 3 and 4. In one embodiment, the positioning component A100 may further include a rotating base A140. The rotating base A140 is rotatably mounted on the second positioning component A120 and connected to the first positioning component A110, so that the first positioning component A110 can be rotated relative to the second positioning component A120 by the rotating base A140 to face different directions, so that it has multiple usage modes (such as rearward mode, lateral mode, etc.).

[0112] Referring to Figure 3, in one embodiment, the second positioning component A120 has a mounting hole A126A and a mounting cavity A126B, and the mounting hole A126A communicates with the mounting cavity A126B. The rotating seat A140 is rotatably disposed within the mounting cavity A126B through the mounting hole A126A. Specifically, the rotating seat A140 has a rotation axis, which is coaxially arranged with the center of the mounting hole A126A. The rotating seat A140 rotates approximately around the rotation axis to drive the first positioning component A110 to rotate. In this embodiment, the rotating seat A140 is generally disk-shaped, and the aforementioned rotation axis can be regarded as the center of the rotating seat A140. Of course, in other embodiments, the rotating seat A140 can also be other symmetrical structures (such as ellipse, rectangle, etc.), and the rotation axis can be the geometric center of the rotating seat A140 or a position off from the geometric center; or, the rotating seat A140 can also be asymmetrical, and the rotation axis can be set according to the actual situation, without specific limitations here. Referring to Figures 3, 6, 7, and 10, in one embodiment, a mounting groove A116 is formed at the bottom of the first positioning component A110. The first end A140A of the rotating seat A140 is inserted into the mounting groove A116, and the rotating seat A140 is fastened to the first positioning component A110 by a connector A117 (such as a bolt or screw). In one embodiment, a limiting flange A141 is formed at the second end A140B of the rotating seat A140 (i.e., the end away from the first positioning component A110). A pressing part A126C protrudes from the peripheral wall of the mounting cavity A126B along the radial direction of the mounting hole A126A. The pressing part A126C abuts against the limiting flange A141 in a generally vertical direction. In this way, the rotating seat A140 can be prevented from disengaging from the second positioning component A120 during rotation, thereby improving the reliability and stability of the positioning component A100. Specifically, the limiting flange A141 is arranged around the circumferential direction of the rotating seat A140, and the pressing part A126C extends around the circumferential direction of the mounting hole A126A. In this way, the rotating seat A140 can be evenly pressed against the pressing part A126C along its circumference.

[0113] Referring to Figures 3 and 4, in one embodiment, the first positioning component A110 is provided with a first positioning member A111, and the second positioning component A120 is provided with a limiting groove A127. Specifically, the first positioning member A111 is disposed on the side of the first positioning component A110 facing the second positioning component A120 (i.e., the bottom of the first positioning component A110), and the first positioning member A111 is located at the front end of the first positioning component A110. The limiting groove A127 is disposed on the side of the second positioning component A120 facing the first positioning component A110 (i.e., the top of the second positioning component A120). The first positioning member A111 is inserted into the limiting groove A127 and can move along the limiting groove A127. The first positioning member A111 and the limiting groove A127 are mutually limiting to restrict the angular range of rotation of the first positioning component A110 relative to the second positioning component A120 by means of the rotating seat A140. Specifically, the limiting groove A127 is an arc-shaped groove and is set around the rotation axis (or mounting hole A126A) of the rotating seat A140. The end walls at both ends of the limiting groove A127 are called stop walls A1271. When the first positioning component A110 rotates with the rotating seat A140 around a certain direction (such as clockwise) until the first positioning component A111 abuts against a stop wall A1271, the first positioning component A110 and the rotating seat A140 will be unable to continue rotating in the same direction (such as clockwise). Specifically, the range of rotation angle of the rotating seat A140 is related to the arc length of the limiting groove A127. More specifically, in this embodiment, the arc-shaped opening of the limiting groove A127 faces the front end of the second positioning component A120. Thus, the rotating seat A140 can drive the first positioning component A110 to rotate relative to the second positioning component A120 to any direction other than forward. This allows the first positioning component A110 to have a lateral mode (see Figure 2) and a rearward mode (see Figure 1) relative to the second positioning component A120. In one embodiment, the limiting groove A127 can be, for example, a 3 / 4 circular groove, a semi-circular groove (i.e., a 1 / 2 circular groove), etc., without specific limitations. Taking the limiting groove A127 as approximately a semi-circular groove as an example, when the first positioning component A110 is in the lateral mode relative to the second positioning component A120, the first positioning member A111 is located at the end of the limiting groove A127 and abuts against the stop wall A1271.

[0114] It should be noted that when the positioning component A100 is installed on a car seat, with the car as a reference, the "rear-facing mode" means that the front end of the first positioning component A110 faces the rear of the car, and the rear end of the first positioning component A110 faces the front of the car. In this case, when the infant is seated inside the vehicle body A200, the infant's face is facing the rear of the car. The "side-facing mode" means that both the front end and the rear end of the first positioning component A110 face the car door. In this case, when the infant is seated inside the vehicle body A200, the infant's face is facing the car door. Specifically, the "side-facing mode" includes a left-facing mode where the front end of the first positioning component A110 faces the left door, and its rear end faces the right door; and a right-facing mode where the front end of the first positioning component A110 faces the right door, and its rear end faces the left door.

[0115] Referring to Figures 3, 4, and 7, in one embodiment, the second positioning component A120 is provided with a second positioning member A128, and the second positioning member A128 is located at the rear end of the second positioning component A120. Specifically, a portion of the structure of the second positioning member A128 extends into the limiting groove A127. When the first positioning component A110 is in the rearward mode, the first positioning member A111 and the second positioning member A128 abut against each other approximately vertically (see Figure 7), thus further restricting the first positioning component A110 from disengaging from the second positioning component A120 in the vertical direction. When a collision or emergency braking occurs, the vehicle body A200 tends to tilt towards the front of the vehicle under the action of inertial force, thereby causing the first positioning component A110 to tend to disengage from the second positioning component A120. When the first positioning member A111 on the first positioning component A110 is pressed against the second positioning member A128, the second positioning member A128 can press against the first positioning member A111, and in turn can press against the first positioning component A110, so as to prevent the vehicle body A200 and the first positioning component A110 from detaching from the second positioning component A120, thereby improving the safety of the vehicle body A200.

[0116] Referring to Figures 4 and 7, in one embodiment, the first positioning member A111 includes a first fixing segment A111A, a connecting segment A111B, and a second fixing segment A111C. The first fixing segment A111A is connected to the bottom of the first positioning assembly A110. The first fixing segment A111A and the second fixing segment A111C are connected via the connecting segment A111B. The first fixing segment A111A and the second fixing segment A111C are opposite to each other and spaced apart. The space between the first fixing segment A111A, the connecting segment A111B, and the second fixing segment A111C forms an open pressure groove A111D. When the first positioning member A111 is inserted into the limiting groove A127, a certain gap is maintained between the first positioning member A111 and both the inner and outer sidewalls of the limiting groove A127 in the width direction of the limiting groove A127.

[0117] Referring to Figures 3 and 7, in one embodiment, the second positioning member A128 includes a support section A128A and a pressing section A128B. The support section A128A and the pressing section A128B are connected and set at an angle, and the angled area between them forms a limiting portion A128C. One end of the support section A128A away from the pressing section A128B is connected to the second positioning component A128. The pressing section A128B extends toward the limiting groove A127 so that the limiting portion A128C faces the limiting groove A127. Specifically, as shown in Figure 7, when the first positioning component A110 is in the rearward mode, the pressing section A128B of the second positioning member A128 is inserted into the pressing groove A111D and can abut against the connecting section A111B of the first positioning member A111. At the same time, the second fixing section A111C of the first positioning member A111 is inserted into the limiting part A128C and can abut against the supporting section A128A. In this way, the first positioning member A111 can be restricted from disengaging from the second positioning member A128 in a roughly vertical direction, and ultimately the first positioning component A110 can be restricted from disengaging from the second positioning component A120 in a vertical direction.

[0118] In one embodiment, the first positioning component A110 may be provided with one or more first positioning elements A111, and the second positioning component A120 may correspondingly be provided with one or more second positioning elements A128, each second positioning element A128 corresponding to one first positioning element A111. In this embodiment, as shown in Figures 3 and 4, the first positioning component A110 is provided with two first positioning elements A111, and the second positioning component A120 is provided with two second positioning elements A128. The two second positioning elements A128 are located near the rear end of the second positioning component A120 and are circumferentially spaced around the limiting groove A127. In this embodiment, when the first positioning component A110 is in the rearward mode, the two second positioning elements A128 respectively abut against the two first positioning elements A111, thereby forming two first fixed support points.

[0119] In one embodiment, the positioning component A100 may further include a locking mechanism A150. The locking mechanism A150 may be disposed, for example, in one of the rotating base A140 and the second positioning component A120, and is mainly used to restrict or allow the rotating base A140 to rotate relative to the second positioning component A120, thereby restricting or allowing the first positioning component A110 to rotate relative to the second positioning component A120.

[0120] It should be noted that the above-mentioned "locking mechanism A150 is disposed in one of the rotating base A140 and the second positioning component A120" includes two implementations: the locking mechanism A150 is disposed in the rotating base A140; or the locking mechanism A150 is disposed in the second positioning component A120. The two implementations will be briefly described below with reference to the relevant figures.

[0121] Referring to Figures 6, 10, and 11, in the first embodiment of the first aspect, a locking mechanism A150 is disposed on a rotating base A140, and a second positioning component A120 is provided with a second locking portion A1281. The second locking portion A1281 may be, for example, a hole or groove structure located on the inner wall of the mounting cavity A126B. Specifically, the second locking portion A1281 is disposed on the pressing portion A126C (see Figure 6). The locking mechanism A150 is used to lock into the second locking portion A1281 to restrict the rotation of the rotating base A140 relative to the second positioning component A120. Specifically, when the first positioning component A110 is in the rearward mode, the locking mechanism A150 is adapted to lock into the second locking portion A1281. In other words, when the locking mechanism A150 engages with the second locking part A1281, the first positioning component A110 can be locked in the rearward mode, preventing the first positioning component A110 from arbitrarily switching to the lateral mode and ensuring the reliability of the first positioning component A110 when it is in the rearward mode.

[0122] Referring to Figures 6, 10, and 11, in one embodiment, the locking mechanism A150 includes a locking member A151, which is movably disposed on the rotating base A140 and has a first locked position and a first unlocked position. The locking member A151 is used to engage with the second locking part A1281 in a snap-fit ​​manner. Specifically, when the locking member A151 is in the first locked position, the locking member A151 is locked in engagement with the second locking part A1281 (see Figure 6) to restrict the rotation of the rotating base A140 relative to the second positioning component A120. At this time, the front end of the first positioning component A110 faces the rear end of the second positioning component A120, and the first positioning component A110 is locked in a rearward mode. When the locking member A151 is in the first unlocking position, the locking member A151 releases the lock on the second locking part A1281, so as to allow the rotating seat A140 to rotate relative to the second positioning component A120, thereby allowing the first positioning component A110 to switch from the rearward mode to the sideward mode.

[0123] Referring again to Figures 6, 10, and 11, specifically, in this embodiment, the rotating base A140 has an inner cavity A142 and a through hole A143, which communicates with the inner cavity A142. Furthermore, a first mounting bracket A144 is provided in the inner cavity A142, and a locking member A151 is movably disposed on the first mounting bracket A144 and can extend from the through hole A143. When the locking member A151 is in the first locked position, at least a portion of the locking member A151 passes through the through hole A143 to extend into the second positioning assembly A120 and locks into the second locking part A1281. When the locking member A151 is in the first unlocked position, the locking member A151 disengages from the second locking part A1281.

[0124] In this embodiment, the second locking part A1281 is approximately located at the front end of the second positioning component A120. When the first positioning component A110 is in the rearward mode, the locking member A151 locks into the second locking part A1281 to form a second fixed support point. Considering the first fixed support point mentioned earlier, when the first positioning component A110 is in the rearward mode, both the front and rear ends of the first positioning component A110 are supported and fixed by the second positioning component A120. The front and rear ends of the first positioning component A110 can be considered to have two types of fixed support points (i.e., the first fixed support point and the second fixed support point). These two types of fixed support points are arranged one after the other along the direction of the vehicle's movement, thus greatly improving the stability of the first positioning component A110 in the rearward mode.

[0125] In one embodiment, the locking mechanism A150 may further include a first reset member A152 (see Figures 6 and 10). The first reset member A152 may be, for example, an elastic element such as a spring or a sheet, which is used to drive the locking member A151 to reset so that the locking member A151 is held in the first locked position. Specifically, in this embodiment, the first reset member A152 is a compression spring, which abuts against the locking member A151 and the first mounting bracket A144.

[0126] Referring to Figures 10 and 11, in one embodiment, the positioning component A100 may further include a rotary release mechanism A160, which drives and cooperates with the locking mechanism A150 to unlock the locking mechanism A150, thereby allowing the rotating seat A140 to rotate relative to the second positioning component A120. Specifically, the rotary release mechanism A160 includes a rotary release operating member A161 and a first traction member A162. The rotary release operating member A161 is operably disposed on the first positioning component A110, and the first traction member A162 is connected between the rotary release operating member A161 and the locking member A151. When the rotary release operating member A161 is operated, the rotary release operating member A161 drives the locking member A151 to move from a first locked position to a first released position by means of the first traction member A162. Specifically, in this embodiment, the side wall of the rotating seat A140 is also provided with a connecting through hole A146, which communicates with the inner cavity A142. One end of the first traction member A162 is connected to the locking member A151, and the other end passes through the connecting hole A146 to extend out of the rotating seat A140 and is connected to the rotating release operation member A161.

[0127] In one embodiment, a rotary release operation member A161 is movably disposed on the first positioning component A110, and at least one rotary release operation member A161 may be provided. Specifically, in this embodiment, two rotary release operation members A161 are provided on the first positioning component A110, and the two rotary release operation members A161 are respectively located on the left and right sides of the first positioning component A110. In this way, regardless of whether the user is standing on the left side door or the rear door, he / she can release the locking mechanism A150 by operating the nearest rotary release operation member A161.

[0128] In one embodiment, the positioning component A100 may further include, for example, an indicating mechanism A170, which is disposed on the second positioning component A120 and drivesly engages with the rotary seat A140, and is used to detect whether the first positioning component A110 has rotated into position to be in the rearward mode. In other words, the user can determine whether the first positioning component A110 is in the rearward mode by using the indicating mechanism A170.

[0129] Referring to Figures 11 to 14, in one embodiment, the indicating mechanism A170 includes a display window A171 and an indicating element A172. Specifically, the display window A171 is disposed on the second positioning component A120. The indicating element A172 may include, for example, a first indicating area A1721 and a second indicating area A1722. The indicating element A172 is pivotally connected to the second positioning component A120 and abuts against the rotating seat A140, so that the indicating element A172 has a first indicating position and a second indicating position. When the first positioning component A110 is in the rearward mode, the indicating element A172 is in the first indicating position, and the first indicating area A1721 is directly opposite the display window A171 (i.e., the display window A171 exposes the first indicating area A1721). When the first positioning component A110 is in the lateral mode, the indicating element A172 is in the second indicating position, and the second indicating area A1722 is directly opposite the display window A171 (i.e., the display window A171 exposes the second indicating area A1722).

[0130] In one embodiment, the first indicator area A1721 has a first color block (such as one of red, green, or yellow), and the second indicator area A1722 has a second color block (such as one of yellow or purple). For example, in this embodiment, the first color block is green, and the second color block is red. When the indicator A172 pivots between the first and second indicator positions, the first and second color blocks selectively face the display window A171. Thus, the user can view the displayed colors through the display window A171 to determine whether the first positioning component A110 has rotated to the correct position for rearward mode. Specifically, when the display window A171 displays only red, it can be understood that the first positioning component A110 is in lateral mode. When the display window A171 displays both red and green, the first positioning component A110 is between the rearward and lateral usage modes; in this case, it can be understood that the first positioning component A110 has not rotated to the correct position for rearward mode. When the display window A171 shows all green colors, it can be understood that the first positioning component A110 has rotated into position and is in backward mode.

[0131] Referring to Figures 12 and 13, in one embodiment, the peripheral wall of the rotating base A140 has a recess A145, and the indicator A172 has a pushing portion A1723. When the first positioning component A110 is in the rearward mode, the pushing portion A1723 abuts against the recess A145 to pivot the indicator A172 to a first indicating position. When the first positioning component A110 is in the lateral mode, the pushing portion A1723 retracts from the recess A145 to pivot the indicator A172 to a second indicating position. Specifically, in this embodiment, the rotating seat A140 is generally disk-shaped, and the recess A145 is recessed relative to the peripheral wall of the rotating seat A140. When the indicator A172 abuts against the recess A145, the indicator A172 is in the first indicating position. When the rotating seat A140 rotates clockwise or counterclockwise, the rotating seat A140 pushes against the pushing part A1723 of the indicator A172, causing the indicator A172 to pivot. The pushing part A1723 gradually withdraws from the recess A145 and abuts against the peripheral wall of the rotating seat A140. During this process, the indicator A172 gradually pivots to the second indicating position. It should be noted that in this embodiment, the recess A145 is provided on the side wall of the limiting flange A141 of the rotating seat A140. In layman's terms, the recess A145 can be regarded as a structure formed by the recess of part of the side wall of the limiting flange A141.

[0132] Referring to Figures 12 to 14, in one embodiment, the indicating mechanism A170 may further include a fourth reset member A173. The fourth reset member A173 may be, for example, an elastic element such as a spring or sheet, which is used to drive the indicating member A172 to reset so that the indicating member A172 is held in the first indicating position. Specifically, when the rotating seat A140 rotates clockwise or counterclockwise to switch the first positioning component A110 from the rearward mode to the lateral mode, the rotating seat A140 will push the indicating member A172 to pivot, thereby driving the pushing part A1723 to gradually exit from the recess A145 and abut against the peripheral wall of the rotating seat A140. During this process, the indicating member A172 pivots to the second indicating position, the display window A171 is displayed in red, and the fourth reset member A173 is stretched. Based on this, when the rotating base A140 rotates to reset in a counterclockwise or clockwise direction, so that the first positioning component A110 switches from the lateral mode to the rearward mode, when the rotating base A140 pivots until the recess A145 is opposite to the pushing part A1723, the indicator A172 can automatically pivot from the second indicating position to the first indicating position under the reset force of the fourth reset member A173. At this time, the display window A171 is green. It should be noted that since the rotating base A140 is roughly disc-shaped, when the pushing part A1723 of the indicator A172 abuts against the peripheral wall of the rotating base A140 excluding the area of ​​the recess A145, the indicator A172 remains stationary and maintains the second indicating position.

[0133] Referring again to Figures 12 and 13, to improve the smoothness of the pivoting of the indicator A172, in one embodiment, the peripheral wall of the rotating seat A140 is further provided with a guide ramp A147. The guide ramp A147 is connected to the recess A145. When the first positioning component A110 switches from a rearward mode to a lateral mode, the pushing part A1723 is adapted to retract from the recess A145 through the guide ramp A147. In this embodiment, guide ramps A147 are provided on both the left and right sides of the recess A145 along the circumferential direction of the rotating seat A140. When the rotating seat A140 rotates in different directions, the pushing part A1723 selectively abuts against one of the two guide ramps A147 to guide the engagement. Specifically, for example, when the first positioning component A110 switches from a rearward mode to a leftward lateral mode, the rotating base A140 rotates counterclockwise around its central axis, so that one of the guide ramps A147 can guide the pushing part A1723 to retract from the recess A145. When the first positioning component A110 switches from a rearward mode to a rightward lateral mode, the rotating base A140 rotates clockwise around its central axis, so that the other guide ramp A147 can guide the pushing part A1723 to retract from the recess A145.

[0134] As described above, the first positioning component A110 is connected to the vehicle body A200 via a connecting mechanism A180. Specifically, the connecting mechanism A180 has a locked state and an unlocked state. When the connecting mechanism A180 is in the locked state, it is adapted to be connected to the vehicle body A200; when the connecting mechanism A180 is in the unlocked state, it is detached from the vehicle body A200. Therefore, in this embodiment, the first positioning component A110 is detachably connected to the vehicle body A200 via the connecting mechanism A180.

[0135] Referring to Figures 1, 15, and 16, in one embodiment, the connecting mechanism A180 may include a locking hook A181, which is pivotally connected to the first positioning component A110 and has a second locking position and a second unlocking position. When the locking hook A181 is in the second locking position, it engages with the vehicle body A200. When the locking hook A181 is in the second unlocking position, it releases the lock on the vehicle body A200. Specifically, the connecting mechanism A180 may further include a locking groove A182, which is disposed on the first positioning component A110 and is used to accommodate the locking rod of the vehicle body A200. The engaging hook A181 pivots relative to the first positioning component A110 and extends into the engaging groove A182 to close the opening of the groove A182. This confines the engaging rod at the bottom of the vehicle body A200 within the engaging groove A182, ultimately achieving a detachable connection between the vehicle body A200 and the first positioning component A110. More specifically, when the engaging hook A181 is in the second locked position, it extends at least partially into the engaging groove A182 to seal the opening of the groove (as shown in Figure 15). This confines the engaging rod within the engaging groove A182, achieving a locking engagement between the engaging hook A181 and the engaging rod. When the engaging hook A181 is in the second unlocked position, it retracts from the engaging groove A182, opening the groove. This allows the engaging rod to disengage from the opening of the engaging groove A182.

[0136] Specifically, in this embodiment, the bottom of the vehicle body A200 is typically provided with at least two engaging rods along the front-to-back direction. Correspondingly, the first positioning component A110 has at least two rows of engaging slots A182, and the distance between two adjacent rows of engaging slots A182 is approximately equal to the distance between two adjacent engaging rods at the bottom of the vehicle body A200. When the vehicle body A200 is installed onto the first positioning component A110, the two adjacent rows of engaging slots A182 engage with the two adjacent engaging rods respectively. Specifically, in this embodiment, the bottom of the vehicle body A200 is provided with two engaging rods, and the first positioning component A110 is provided with two rows of engaging slots A182 (see Figures 5 and 15). Of course, in other embodiments, the bottom of the vehicle body A200 may also be provided with three, four, or more engaging rods, and the first positioning component A110 may also have three, four, or more rows of engaging hooks A181, which are not specifically limited here. In one embodiment, each row of engaging slots A182 includes at least one engaging slot A182. Specifically, the row of engaging slots A182 near the front end of the first positioning component A110 is referred to as the first row of engaging slots A182A, and the row of engaging slots A182 near the rear end of the first positioning component A110 is referred to as the second row of engaging slots A182B. The first row of engaging slots A182A includes two engaging slots A182, and the second row of engaging slots A182B includes one engaging slot A182. Of course, in other embodiments, the first row of engaging slots A182A may include one engaging slot A182, and the second row of engaging slots A182B may include two engaging slots A182; no specific limitation is made here. It should be noted that in this embodiment, the number of engaging slots A182 is the same as the number of engaging hooks A181, and they correspond one-to-one. Specifically, each engaging slot A182 has a corresponding engaging hook A181 that can extend into one of its closed slots.

[0137] Referring to Figure 15, in one embodiment, the connecting mechanism A180 may further include a third reset member A183. The third reset member A183 may be an elastic element such as a spring, sheet, or torsion spring, which is used to drive the engaging hook A181 to reset so that the engaging hook A181 is held in the second locked position. In other words, in its natural state, the engaging hook A181 is normally held in the second locked position by the action of the third reset member A183 to lock the opening of the engaging groove A182.

[0138] Referring to Figures 15 and 16, to facilitate user control of the state of the connecting mechanism A180, in one embodiment, the positioning component A100 may further include a connecting release mechanism A190. This connecting release mechanism A190 is disposed on the first positioning component A110 and engages with the locking hook A181. When the connecting release mechanism A190 is operated, it can drive the locking hook A181 to switch from a second locked position to a second released position.

[0139] The engaging hook A181 located at the first row of engaging slots A182A is referred to as the first row engaging hook A181A, and the engaging hook A181 located at the second row of engaging slots A182 is referred to as the second row engaging hook A181. In this embodiment, the first row engaging hook A181 and the second row engaging hook A181 are arranged opposite to each other (which can be considered as the hook bodies of the two rows of engaging hooks A181 facing opposite directions). Specifically, taking the perspective of Figure 16 as an example, when the first row engaging hook A181 pivots from the second locking position to the second unlocking position, it rotates clockwise, and when it pivots from the second unlocking position to the second locking position, it rotates counterclockwise. Conversely, when the second row engaging hook A181 pivots from the second locking position to the second unlocking position, it rotates counterclockwise, and when it pivots from the second unlocking position to the second locking position, it rotates clockwise.

[0140] Referring to Figures 15 and 16, in one embodiment, the connection release mechanism A190 includes a linkage A191 and a connection release operation component A192. The linkage A191 is movably disposed on the first positioning component A110 and drives the engagement hook A181. The connection release operation component A192 is operably disposed on the first positioning component A110 and drives the linkage A191. When the connection release operation component A192 is operated, it drives the engagement hook A181 from a second locked position to a second released position via the linkage A191. Thus, the user can control the position of the engagement hook A181 (or the state of the connection mechanism A180) by operating the connection release operation component A192.

[0141] Referring again to Figures 15 and 16, in one embodiment, the connection / release operation assembly A192 includes a first operating element A1921 and a second operating element A1922. Both the first operating element A1921 and the second operating element A1922 are pivotally connected to the first positioning assembly A110 and are respectively drivenly connected to the linkage A191. The second operating element A1922 and the first operating element A1921 are spaced apart circumferentially along the first positioning assembly A110. Specifically, the first operating element A1921 and the second operating element A1922 are positioned opposite each other, with one located at the front end of the first positioning assembly A110 and the other at the rear end (see Figures 3 and 5). Therefore, when the first positioning assembly A110 is in the rearward mode, one of the first operating elements A1921 and the second operating element A1922 is suitable for operation. When the first positioning component A110 is in the lateral mode, the other of the first operating element A1921 and the second operating element A1922 is suitable for operation. In this embodiment, the first operating element A1921 is located at the front end of the first positioning component A110, and the second operating element A1922 is located at the rear end of the first positioning component A110. When the first positioning component A110 is in the rearward mode, since the first operating element A1921 is located between the vehicle body A200 and the car seat back (or the abutment portion A1212 of the second positioning component A120), the operating space of the first operating element A1921 is relatively small, while the second operating element A1922 faces away from the vehicle body A200 and is not obstructed by the vehicle body A200 and remains exposed (see Figure 1). Therefore, the user can preferentially and selectively operate the second operating element A1922 to release the locking hook A181. When the first positioning component A110 is in the side-facing mode, the first operating member A1921 rotates with the first positioning component A110 to face the user and remains exposed, while the second operating member A1922 rotates with the first positioning component A110 to face away from the user and move away from the user. Therefore, the user can selectively operate the first operating member A1921 to release the locking hook A181.

[0142] Referring to Figures 7 and 16, in one embodiment, the first operating member A1921 includes a first pivot portion A19211, a first driving portion A19212, and a first operating portion A19213. The first pivot portion A19211 is located between the first driving portion A19212 and the first operating portion A19213. The first operating member A1921 is pivotally connected to the first positioning component A110 through the first pivot portion A19211. The first operating portion A19213 is used for user operation (such as pressing). The first driving portion A19212 is driven and cooperates with the linkage A191. Specifically, one of the first driving part A19212 and the linkage A191 is provided with a first driving groove A1921A, and the other is provided with a first driving pin A193. The first driving pin A193 is movably inserted into the first driving groove A1921A and can move along the extension direction of the first driving groove A1921A. Specifically, the first driving groove A1921A is a strip groove or a waist-shaped hole, etc. Referring to the perspective of Figure 16, when the user presses down on the first operating part A19213, for example, the first operating part A1921 rotates counterclockwise around the first pivot part A19211. Under the guidance of the first driving groove A1921A and the first driving pin A193, the linkage A191 is moved.

[0143] Referring to Figures 9 and 16, similarly, the second operating member A1922 includes a second pivot portion A19221, a second drive portion A19222, and a second operating portion A19223. The second pivot portion A19221 is located between the second drive portion A19222 and the second operating portion A19223. The second operating member A1922 is pivotally connected to the first positioning component A110 via the second pivot portion A19221. The second operating portion A19223 is used for user operation (such as pushing). The second drive portion A19222 is driven and cooperates with the linkage A191. Specifically, one of the second drive unit A19222 and the linkage A191 is provided with a second drive groove A1922A, and the other is provided with a second drive pin A194. The second drive pin A194 is movably inserted into the second drive groove A1922A and can move along the extension direction of the second drive groove A1922A. Specifically, the second drive groove A1922A is a strip groove or a waist-shaped hole, etc. When the user pushes the second operating part A19223 upward, for example, the second operating part A1922 rotates counterclockwise around the second pivot part A19221. Under the guidance of the second drive groove A1922A and the second drive pin A194, the linkage A191 is moved, thereby driving the locking hook A181 to switch from the second locked position to the second unlocked position.

[0144] Referring to Figures 15 and 16, in one embodiment, the linkage A191 further includes a transmission portion A1911. The connection release mechanism A190 also includes a transmission portion A193, which is pivotally connected between the transmission portion A1911 and the engaging hook A181. When the connection release operation assembly A192 (such as the first operation member A1921 or the second operation member A1922) is operated, the connection release operation assembly A192 drives the transmission portion A1911 to move the transmission portion A193, causing the transmission portion A193 to drive the engaging hook A181 to switch from a second locked position to a second released position.

[0145] In one embodiment, the linkage A191 has a pushing portion A1912, which engages with the locking hook A181. When the connection release operation assembly A192 (such as the first operation member A1921 or the second operation member A1922) is operated, the connection release operation assembly A192 drives the locking hook A181 to switch from a second locked position to a second released position via the pushing portion A1912. Specifically, the pushing portion A1912 engages with the locking hook A181 pivotally connected to the second row of locking slots A182B, thereby enabling the locking hook A181 to switch from a second locked position to a second released position.

[0146] The working principle and process of the connecting mechanism A180 are briefly explained below with reference to relevant diagrams.

[0147] Referring to Figure 15, when the connecting mechanism A180 is in the locked state, each locking hook A181 is kept in the second locked position under the action of the corresponding third reset member A183. In this way, each locking hook A181 can restrict the locking rod in the locking groove A182.

[0148] Referring to Figures 15 and 16, when the user needs to remove the vehicle body A200 from the first positioning component A110, that is, when the connecting mechanism A180 needs to be switched from the locked state to the unlocked state, the user can preferentially select the first operating member A1921 or the second operating member A1922 to release the locking hook A181 according to the usage mode of the first positioning component A110. Specifically, when the first operating member A1921 or the second operating member A1922 is operated, the first operating member A1921 or the second operating member A1922 will drive the linkage member A191 to move from the front end to the rear end of the first positioning component A110. At this time, the transmission part A1911 of the linkage member A191 will pull the transmission member A193 to move towards the rear end of the first positioning component A110. The transmission member A193 will pull the locking hook A181 at the first row of locking grooves A182A to pivot clockwise to the second unlocking position. At the same time, the pushing part A1912 on the linkage member A191 will push the locking hook A181 located at the second row of locking grooves A182B to pivot counterclockwise to the second unlocking position.

[0149] In one embodiment, the connecting mechanism A180 may further include a sixth reset member A184 (refer to Figures 9 and 15). The sixth reset member A184 may be an elastic element such as a spring or sheet, which is used to drive the linkage A191 to automatically reset. When the user does not operate the first operating member A1921 or the second operating member A1922, the locking hook A181 automatically resets to the second locked position under the action of the third reset member A183, and the linkage A191 automatically resets under the action of the sixth reset member A184, thereby driving the first operating member A1921 and the second operating member A1922 to automatically reset, so that the user can perform the unlocking operation next time.

[0150] Figure 17 shows a perspective view of 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, including components such as a first positioning component A110 and a 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 above. The following mainly describes the differences between this embodiment and the first embodiment of the first aspect described above.

[0151] In a second embodiment of the first aspect, a locking mechanism A150 is disposed on a second positioning component A120. A first positioning component A110 has a first locking portion A1111, and a second positioning component A120 has a second locking portion A1281. When the first positioning component A110 is in a rearward mode, the locking mechanism A150 is adapted to lock into the first locking portion A1111 and the second locking portion A1281.

[0152] In this embodiment, as shown in FIG18, the first positioning member A111 can also cooperate with the limiting groove A127 to limit the rotation angle of the rotating seat A140. Optionally, the first positioning member A111 can also abut against the second positioning member A128 in a generally vertical direction to limit the first positioning component A110 from disengaging from the second positioning component A120. Specifically, in this embodiment, the first positioning member A111 can cooperate with and lock the second positioning member A128 to limit the first positioning component A110 from rotating relative to the second positioning component A120 by means of the rotating seat A140. Specifically, in this embodiment, as shown in FIG18 to FIG20, the first positioning member A111 is provided with a first locking part A1111, and the second positioning member A128 is provided with a second locking part A1281. The locking mechanism A150 includes a locking member A151, which is movably disposed on the second positioning component A120 and has a first locking position and a first unlocking position. When locking member A151 is in the first locked position, locking member A151 engages with the first locking part A1111 and the second locking part A1281 to restrict the rotation of the first positioning component A110 relative to the second positioning component A120. When locking member A151 is in the first unlocked position, locking member A151 releases the lock on the first locking part A1111 and the second locking part A1281 to allow the first positioning component A110 to rotate relative to the second positioning component A120. In this embodiment, both the first positioning part A111 and the second positioning part A128 are provided. The first positioning part A111 is located approximately at the front end of the first positioning component A110, and the second positioning part A128 is located approximately at the rear end of the second positioning component A120 and approximately at the midpoint of the limiting groove A127. Locking member A151 is substantially movably disposed at the rear end of the second positioning component A120.

[0153] Please refer to Figures 18 to 20. In one embodiment, the first locking part A1111 includes a first through hole A1112. Specifically, in this embodiment, the second positioning member A128 has a U-shaped structure, and the second locking part A1281 includes a second through hole A12811 and a third through hole A12812, which are respectively located on opposite side walls of the second positioning member A128. When the first positioning component A110 is in the rearward mode, the first positioning member A111 is inserted into the U-shaped groove of the second positioning member A128, and the locking member A151 passes through the second through hole A12811, the first through hole A1112, and the third through hole A12812 in sequence. In this way, the rotation of the first positioning component A110 relative to the second positioning component A120 can be restricted, so that the first positioning component A110 is stably maintained in the rearward mode.

[0154] Referring to Figures 18 to 21, in this embodiment, the structure of the locking mechanism A150 is slightly different from that of the locking mechanism A150 in the first embodiment of the first aspect. Specifically, the locking mechanism A150 in this embodiment further includes a driving member A153, which is movably disposed in the second positioning component A120 and configured to drive and cooperate with the locking member A151. In other words, the user can switch the locking member A151 between a first locked position and a first unlocked position by changing the position of the driving member A153.

[0155] In this embodiment, as shown in Figures 18 and 21, the second positioning component A120 is provided with a second mounting bracket A129, and the driving member A153 is movably mounted on the second mounting bracket A129. Specifically, the driving member A153 can move vertically relative to the second mounting bracket A129 and has a first position and a second position, with the first position located above the second position. Specifically, the driving member A153 is provided with a guide hole A1531, which extends obliquely relative to the moving direction of the driving member A153. The locking member A151 is horizontally disposed and passes through the second mounting bracket A129. The locking member A151 has a guide post A1511, which can extend into the guide hole A1531 and slide in cooperation with the guide hole A1531. When the first driving member A153 is in the first position, the locking member A151 is in the first locked position; when the first driving member A153 is in the second position, the locking member A151 is in the first unlocked position. In this way, the position of locking member A151 can be changed by pressing it against the locking member A151.

[0156] In this embodiment, as shown in Figures 19 and 20, the locking mechanism A150 may also include a first reset member A152, but the first reset member A152 is used to drive the driving member A153 to reset so that the driving member A153 is held in the first position. In this way, the locking member A151 can be driven to move from the first unlocking position to the first locking position (or it can be regarded as driving the locking member A151 to be held in the first locking position).

[0157] In this embodiment, the structure of the rotary release mechanism A160 differs from the structure of the rotary release mechanism A160 in the first embodiment of the first aspect. Specifically, the rotary release mechanism A160 is disposed on the first positioning component A110 and is adapted to be driven and cooperated with the driving member A153. The rotary release mechanism A160 drives the locking member A151 to move from the first locked position to the first released position by the driving member A153.

[0158] In one embodiment, as shown in Figures 17 and 19 to 21, the rotary release mechanism A160 includes a rotary release operation member A161, a first transmission assembly A163, and a first traction member A162. The rotary release operation member A161 is operably disposed on a first positioning assembly A110. The first transmission assembly A163 is disposed on the first positioning assembly A110 and configured to drive a driving member A153 to move. The first traction member A162 connects the rotary release operation member A161 and the first transmission assembly A163. Specifically, when the rotary release operation member A161 is operated, it drives the first transmission assembly A163 to move via the first traction member A162, causing the driving member A153 to drive the locking member A151 from a first locked position to a first released position.

[0159] In one embodiment, as shown in Figures 17 and 18, the first positioning component A110 includes a first upper housing A112 and a first lower housing A113. The first upper housing A112 and the first lower housing A113 are connected vertically to form a receiving cavity A114 (see Figure 19). Specifically, a rotary unlocking operation member A161 is operably disposed in the first upper housing A112, and a first transmission component A163 is disposed within the receiving cavity A114. Specifically, the first transmission component A163 includes a push seat A1631 and a push rod A1632. The push seat A1631 is movably disposed within the receiving cavity A114 and connected to the first traction member A162. The push rod A1632 is connected to the push seat A1631 and is adapted to pass through the receiving cavity A114 of the first positioning component A110 to push the driving member A153 to move. When the first traction member A162 drives the pusher seat A1631 to move downwards approximately vertically, the pusher seat A1631 drives the push rod A1632 to move downwards simultaneously to push the drive member A153 from the first position to the second position. In this embodiment, the first transmission assembly A163 may also include a seventh reset member A164. The seventh reset member A164 may be an elastic element such as a spring or sheet, which abuts between the pusher seat A1631 and the first lower housing A113 of the first positioning assembly A110, and is used to drive the pusher seat A1631 to reset so that the push rod A1632 disengages from the drive member A153.

[0160] In one embodiment, as shown in Figures 19 to 21, the first transmission assembly A163 may further include a guide wheel A165, which is rotatably disposed within the receiving cavity A114 of the first positioning assembly A110. The two ends of the first traction member A162 pass around the guide wheel A165 and are respectively connected to the push seat A1631 and the rotary release operation member A161. Thus, when the rotary release operation member A161 (see Figure 17) is operated (e.g., pulled, pushed, or rotated), under the guidance of the guide wheel A165, the first traction member A162 pulls the push seat A1631 to move. The push seat A1631 pushes the push rod A1632 downwards in a generally vertical direction, thereby causing the push rod A1632 to pass through the first positioning assembly A110 and press against the drive member A153.

[0161] Please continue to refer to Figures 19 to 21. In one embodiment, the first transmission assembly A163 may further include a fixing cover A166. The fixing cover A166 is installed in the receiving cavity A114 of the first positioning assembly A110 and covers the outside of components such as the push seat A1631, the push rod A1632, and the guide wheel A165, for the purpose of protecting components such as the push seat A1631, the push rod A1632, and the guide wheel A165.

[0162] In this embodiment, the rotary release operation member A161 is the same as in the first embodiment of the first aspect. Two rotary release operation members A161 are provided and movably disposed on the first upper housing A112 of the first positioning component A110. The two rotary release operation members A161 are located on the left and right sides of the first positioning component A110, respectively. The rotary release operation member A161 drives the pusher seat A1631 to move via the corresponding first traction member A162. Specifically, the surface of the first upper housing A112 is provided with a recessed operating groove A1121 (see Figure 17), and the rotary release operation member A161 is movably disposed in the operating groove A1121. In this embodiment, as shown in Figures 19 and 20, the first traction member A162 includes, for example, a traction rope A1621, which is directly connected between the rotary release operation member A161 and the pusher seat A1631. When the user's hand is inserted into the operating groove A1121 to pull or push the rotary release mechanism A161, the rotary release mechanism A161 directly drives the traction rope A1621 to move. Under the guidance of the guide wheel A165, the traction rope A1621 pulls the push seat A1631 to move downward in a roughly vertical direction.

[0163] Of course, in other embodiments, the rotary release operation member A161 can be pivotally connected to the operation groove A1121 of the first positioning component A110. Specifically, referring to Figures 22 to 24, the rotary release operation member A161 has a third pivot portion A1611 and a third connecting portion A1612. The third pivot portion A1611 and the third connecting portion A1612 are offset from each other and are roughly distributed at both ends of the rotary release operation member A161. The rotary release operation member A161 is rotatably disposed in the operation groove A1121 through the third pivot portion A1611. The third connecting portion A1612 is used to connect the first traction member A162. In this way, when the rotary release operation member A161 rotates around the third pivot portion A1611, it can drive the first traction member A162 to move through the third connecting portion A1612 to drive the push seat A1631 to move. More specifically, referring to Figures 20 and 25, the first traction member A162 is a flexible element, which includes, for example, a traction rope A1621 and a traction sleeve A1622 movably sleeved outside the traction rope A1621. The traction sleeve A1622 is a bendable sheath and has a first sleeve end A16221 and a second sleeve end (not shown in the figures). The traction rope A1621 has a first rope end A16211 adjacent to the first sleeve end A16221 and a second rope end A16212 adjacent to the second sleeve end. Specifically, the first end A16211 of the traction rope A1621 is connected to the third connecting part A1612 of the rotary release operating member A161, the second end A16212 of the traction rope A1621 is connected to the push seat A1631, and the first end A16221 and the second end of the traction sleeve A1622 are both connected to the first positioning component A110. The traction sleeve A1622 is used to protect the traction rope A1621. It should be noted that, in this embodiment, when the user needs to rotate the rotary release operating member A161, the applied pushing or pulling force is approximately along the tangential direction of the outer peripheral wall of the rotating seat A140.

[0164] Referring to Figures 26 and 27, in this embodiment, a recessed pressing recess A1131 is formed on the lower surface of the first lower housing A113. This pressing recess A1131 can be considered as protruding into the accommodating cavity A114 and forming a pressing plane A1132. Specifically, a clamping portion A1141 is formed between the pressing plane A1132 and the bottom of the operating groove A1121. The third connecting portion A1612 of the rotary release operating member A161 extends into the clamping portion A1141. In this way, the first rope end A16211 of the traction rope A1621 and the third connecting portion A1612 of the rotary release operating member A161 can be clamped in the clamping portion A1141 to prevent the first rope end A16211 from disengaging from the third connecting portion A1612, and also to prevent the rotary release operating member A161 from swaying up and down during rotation around the third pivot portion A1611.

[0165] In this embodiment, when the first positioning component A110 switches from a rearward mode to a lateral mode via the rotating base A140, the driving component A153 automatically resets to the first position under the action of the first reset component A152, simultaneously driving the locking component A151 to reset to the first locked position. At this time, the locking component A151 passes through the second through hole A12811 and the third through hole A12812 of the second positioning component A128 in sequence (see Figure 18). To prevent the locking component A151 from interfering with the first positioning component A111 when the first positioning component A110 switches from a lateral mode to a rearward mode, thus restricting the first positioning component A110 from switching to the rearward mode, in one embodiment, as shown in Figures 28 and 29, a pushing component A115 is provided on the side of the first positioning component A110 facing the second positioning component A120. At least one of the pushing component A115 and the driving component A153 is provided with a pushing inclined surface A1151 for driving the driving component A153 to move. Specifically, in this embodiment, the pusher A115 is provided with a pusher slope A1151. During the process of the first positioning component A110 rotating in a rearward mode by means of the rotating seat A140, the pusher slope A1151 will push the drive component A153 to move from the first position to the second position. In this way, the locking component A151 can be switched from the first locking position to the first unlocking position, and the first positioning component A111 can be allowed to be inserted into the U-shaped groove of the second positioning component A128. When the first positioning component A110 rotates to the rearward mode, the pushing inclined surface A1151 no longer pushes against the driving component A153. The second through hole A12811, the first through hole A1112, and the third through hole A12812 are aligned. Under the action of the first reset component A152, the driving component A153 can drive the locking component A151 to automatically pass through the second through hole A12811, the first through hole A1112, and the third through hole A12812 to lock the first positioning component A111 and the second positioning component A128.

[0166] The aforementioned vehicle A1000 and positioning component A100 have at least the following technical effects:

[0167] The aforementioned vehicle A1000 includes a positioning component A100. Within this positioning component A100, a first positioning component A110 is used to mount the vehicle body A200. This first component A110 can rotate relative to the second positioning component A120 via a rotating base A140, allowing the vehicle body A200 to rotate accordingly. After the positioning component A100 is connected to the car seat, when it is necessary to connect or disconnect the vehicle body A200 from the positioning component A100, the user can directly rotate the first positioning component A110 to a side-facing mode. This adapts to the user's operating position when standing near the car door, facilitating the user's reach to engage or disengage the vehicle body A200 from the positioning component A100. This allows the user to easily connect or disconnect the vehicle body A200 from the positioning component A100 while standing near the car door, reducing the need for the user to bend over and extend their upper body into the car to operate the vehicle body A200, thus reducing the risk of the user bumping into the door frame and improving safety. This will allow users to connect or detach the vehicle body A200 carrying infants and toddlers from the positioning component A100 without having to separate the vehicle body A200 and the infants and toddlers into two separate steps when putting them into or taking them out of the car.

[0168] If the vehicle body A200 remains connected to the positioning component A100, when a child needs to be placed on the vehicle body A200, the user can directly rotate the first positioning component A110 to the side-facing mode. This will cause the vehicle body A200 to face the car door, making it convenient for the user to place the infant / toddler into the vehicle body A200 while standing near the door, without having to bend over and reach into the car to place the infant / toddler. Similarly, when the infant / toddler needs to be removed, the first positioning component A110 can be rotated to the side-facing mode, causing the vehicle body A200 to also face the car door. The user can then stand at the car door and remove the infant / toddler without bending over and reaching into the car to retrieve the child. This design not only improves the ease of use of the positioning component A100 but also reduces the risk of the user and infant / toddler bumping into the door frame during placement or removal, thus improving safety. In addition, the positioning component A100 is also provided with a locking mechanism A150, which is used to restrict or allow the rotating seat A140 to rotate relative to the second positioning component A120. Therefore, the user can improve the stability of the first positioning component A110 by means of the locking mechanism A150 and prevent the first positioning component A110 from rotating arbitrarily relative to the second positioning component A120.

[0169] Figure 30 is a perspective view of a vehicle B1 according to a second aspect of the present disclosure. According to the present disclosure, the vehicle B1 is mounted on a vehicle seat (not shown) for carrying and protecting children or pets riding in the vehicle. When the vehicle B1 is a child vehicle, it can be in the form of a child seat, a child bassinet, or any other vehicle-mounted vehicle.

[0170] According to this disclosure, the vehicle B1 includes a base B10 (also referred to as the aforementioned positioning component A100) and a vehicle body B20 for carrying passengers. The base B10 and the vehicle body B20 can be detachably connected or fixedly connected, that is, the base B10 can be manufactured separately from the vehicle body B20 and detachably connected, or the base B10 can be manufactured integrally with the vehicle body B20.

[0171] The base B10 includes a base body B100, support legs B200, and two fastening devices B300. The base B10 is mounted on a vehicle seat using the support legs B200 and the fastening devices B300.

[0172] The bottom B110 of the base body B100 rests on the seat of the vehicle seat, and the rear B120 rests against the back of the vehicle seat. According to this embodiment, the rear B120 of the base body B100 is designed to be higher than the front B130, making the upper side of the base B10 sloped. The rear B120 and the bottom B110 form an angle greater than B90 degrees to match the angle formed between the seat and back of the vehicle seat. As can be seen, the bottom B110 is located at the lower end of the base body B100 in the vertical direction, the rear B120 is located at the rear end of the base body B100 in the front-rear direction, and the front B130 is located at the front end of the base body B100 in the front-rear direction. The vehicle body B20 is located above the base B10 in the vertical direction.

[0173] Two fastening devices B300 are provided at the corner between the bottom B110 and the rear B120, and the base B10 can be detachably connected to the vehicle seat at least via the fastening devices B300. The fastening devices B300 are, for example, ISOFIX components.

[0174] According to this embodiment, the support leg B200 is connected to the lower side of the front part B130 of the base body B100. After the base B10 is installed on the vehicle seat, the front part B130 extends forward F outward from the seat portion of the vehicle seat, allowing the support leg B200 to contact the vehicle floor, thereby effectively ensuring the stability of the vehicle B1. The support leg B200 is configured, for example, to be telescopic and / or pivotally folded to the bottom B110 of the base body B100 for storage when not in use.

[0175] As can be seen from the above, the support leg B200 and the fastening device B300 are located on both sides of the base body B100 in the front-back direction, while the two fastening device assemblies B300 are located on both sides of the base body B100 in the left-right direction. The length of the base body B100 in the left-right direction is less than the length of the base body B100 in the front-back direction. Therefore, the front-back direction is the length direction of the base body B100, and the left-right direction is the width direction of the base body B100. According to one embodiment, when installing the base B10 onto the vehicle seat, the user first pivots the support leg B200, which is against the bottom B110, forward and then places the base body B110 flat onto the seat of the vehicle seat. In order to securely connect the base B10 to the vehicle seat, the user generally needs to pull the base B10, which is placed on the seat of the vehicle seat, backward and towards the backrest a certain distance, so that the fastening device B300 can be inserted backward and fixed into the socket between the seat and the backrest of the vehicle seat. After that, the user also needs to push the base B10 so that the rear part B120 of the base body B100 is against the backrest of the vehicle seat. Finally, the user stretches the support leg B200 so that the bottom end of the support leg B200 can contact the vehicle floor, thereby installing the base B10 onto the vehicle seat.

[0176] During the aforementioned pulling and pushing of the base B10, there is mutual friction between the base body B100 and the seat of the vehicle seat. According to this disclosure, the base body B100 is provided with anti-friction parts B400a, B400b, B500a, B50b, and B700 according to Figures 31 to 36 to reduce the scratching of the seat by the base body B100.

[0177] In other embodiments, the base B10 does not have a support leg B200 and a fastening device B300. The base B10 can be installed to the vehicle seat simply by means of a seat belt. However, this type of base B10 also requires the user to push it backward so that the base B10 or the vehicle body B20 rests against the back of the vehicle seat. Therefore, there is mutual friction between the base B10 and the seat of the vehicle seat. Thus, this type of base B10 also needs to be provided with anti-scratch parts B400a, B400b, B500a, B50b, and B700 on its base body B100 to reduce the scratching of the base body B100 on the seat of the vehicle seat.

[0178] Figure 31 shows a bottom perspective view of the base B10 of a vehicle B1 according to an embodiment. The base B10 has a length L and a width W. Support legs B200 are located below the front portion B130, which can be manufactured separately and connected or integrally with the bottom portion B110. Optionally, the lower surfaces of the front portion B130 and the bottom portion B110 are substantially in the same plane. Along the rearward direction B, on the rear side of the bottom portion B110, in the width W direction, receiving portions B150 are provided on both sides of the bottom portion B110 for receiving fastening devices B300. When the base B10 is installed to a vehicle seat, the fastening device B300 extends horizontally rearward from the receiving portion B150 along the rearward direction B to insert into a corresponding socket in the vehicle seat.

[0179] The bottom B110 of the base body B100 is used to contact the seat of the vehicle seat, while the front B130 of the base body B100 is used to protrude forward from the seat of the vehicle seat.

[0180] The rear portion B120 of the base body B100 is used to abut against the backrest of the vehicle seat. Adapting to the angle between the seat and backrest of the vehicle seat, a transition portion B140 is formed between the rear portion B120 of the base body B100 and the bottom portion B110. Two fastening devices B300 are located on either side of this transition portion B140 along the width W direction.

[0181] When installing the base B10 onto the vehicle seat, the user needs to pull the fastening device B300 backwards to insert it into the socket in the vehicle seat, and the user also needs to push the base B10 so that the rear part B120 abuts against the back of the vehicle seat. Therefore, the base body B100 will come into contact with and rub against the vehicle seat, thus scratching the vehicle seat. To address this, according to this disclosure, the base body B100 is provided with anti-abrasion parts B400a, B400b, B500a, B500b, and B700. The anti-abrasion parts B400a, B400b, B500a, B500b, and B700 are provided on the surface of the base body B100 facing the vehicle seat and are exposed on the surface of the base body B100 facing the vehicle seat so as to contact the vehicle seat.

[0182] As shown in Figures 31 to 35, in the illustrated embodiment, the anti-abrasion parts B400a, B400b, B500a, and B500b are all pivotally connected to the base body B100. Specifically, the anti-abrasion parts B400a, B400b, B500a, and B500b can pivot relative to the base body B100 in the front-back direction, so that the user can push the base B10 in the front-back direction. Compared to a base body B100 without anti-friction portions B400a, B400b, B500a, and B500b that can pivot relative to the base body B100, the anti-friction portions B400a, B400b, B500a, and B500b in the illustrated embodiment can contact the vehicle seat through rolling friction, rather than simply through sliding friction. Since sliding friction has a greater frictional force than rolling friction, the anti-friction portions B400a, B400b, B500a, and B500b effectively reduce the friction between the base B10 and the vehicle seat, preventing scratches on the vehicle seat and facilitating the movement of the base B10. Preferably, the anti-friction portions B400a, B400b, B500a, and B500b at least partially protrude from the surface of the base body B100 facing the vehicle seat, allowing them to contact the surface of the vehicle seat first.

[0183] As shown in Figures 31 to 34, according to the illustrated embodiment, the anti-friction parts B400a and B400b include two rolling elements, namely a first roller B410a and a second roller B410b, which cause rolling contact between the base body B100 and the vehicle seat. Optionally, the first roller B410a and the second roller B410b are spaced apart in the front-rear direction. Optionally, both the first roller B410a and the second roller B410b extend in the left-right direction. Optionally, the first roller B410a and the second roller B410b are parallel. Optionally, both the first roller B410a and the second roller B410b are quasi-cylindrical in shape.

[0184] The first roller B410a is disposed along the width W of the base B10 and pivotally located in the transition portion B140. The length of the first roller B410a is at least half the width W of the base B10 corresponding to the position of the first roller B410a, thereby maximizing the contact area between the first roller B410a and the seat of the vehicle seat. Optionally, the first roller B410a can extend from the rear portion B120, the transition portion B140, and the bottom portion B110, that is, the first roller B410a protrudes from the surfaces of the rear portion B120, the transition portion B140, and the bottom portion B110, thereby advantageously preventing the rear portion B120 and the bottom portion B110 from scratching the backrest and seat of the vehicle seat. Since the first roller B410a is located in the transition portion B140, it can be inferred that the first roller B410a is also located between the two fastening devices B300 in the left-right direction. Furthermore, since the transition section B140 connects the rear section B120 and the bottom section B110, meaning the transition section B140 is the foremost point of the base body B100 as it moves rearward, placing the first roller B410a here can effectively reduce the friction between the base body B100 and the seat of the vehicle seat. Optionally, the first roller B410a can also be placed only on the bottom section B110 and close to the rear section B120. In this case, the first roller B410a does not extend from the rear section B120 or the transition section B140, but only protrudes from the surface of the bottom section B110.

[0185] Because the surface of the first roller B410a extends from the base body B100 and is rotatable, the sliding contact between the base body B100 and the vehicle seat is transformed into a rolling contact. This reduces the friction between the base body B100 and the vehicle seat, effectively preventing the base body B100 from scratching the vehicle seat. The first roller B410a can be made of a soft material, such as TPE, silicone, rubber, or TPU. Alternatively, the first roller B410a can be made of a hard material and covered with a replaceable soft material, such as TPE, silicone, rubber, or TPU, to improve the service life of the first roller B410a and effectively prevent excessive friction between the first roller B410a and the seat area of ​​the vehicle seat.

[0186] According to this embodiment, in the length L direction, a second roller B410b is provided in front of the first roller B410a, specifically in front of the bottom B110. The length of the second roller B410b is at least half the width W of the base B10 corresponding to the position of the second roller B410b, thereby maximizing the contact area between the second roller B410b and the seat of the vehicle seat. Optionally, the second roller B410b protrudes from the surface of the bottom B110. Optionally, the material of the second roller B410b can be similar to that of the first roller B410a, made of a soft material such as TPE, silicone, rubber, or TPU, or made of a hard material, and covered with, for example, a replaceable soft material such as TPE, silicone, rubber, or TPU. Optionally, the second roller B410b is located in front of the two fastening devices B300 in the front-rear direction. Optionally, the dimensions of the second roller B410b, such as its length and diameter, can also be substantially equal to those of the first roller B410a. Optionally, the length of the second roller B410b can also be greater than or less than that of the first roller B410a. Because the weight of the base body B100 at the transition portion B140 where the first roller B410a is located is greater than the weight of the bottom portion B110 where the second roller B410b is located, in order to make the contact area between the second roller B410b and the vehicle seat larger than that of the first roller B410a, preferably, the diameter of the second roller B410b is smaller than that of the first roller B410a, that is, the width of the second roller B410b in the front-rear direction is smaller than the width of the first roller B410a in the front-rear direction. Optionally, more additional second rollers B410b may be provided, spaced apart in the front-to-back direction. Some of the second rollers B410b may be aligned with the fastening device B300 in the left-to-right direction, and some of the second rollers B410b may be located in front of the fastening device B300 in the front-to-back direction. The length of the second roller B410b is at least half the width W of the base B10 corresponding to the position of the second roller B410b.

[0187] According to this disclosure, the first roller B410a can cooperate with the second roller B410b to provide better scratch protection for the bottom B110 and rear B120 of the base body B100. Since the frictional force of rolling friction is less than that of sliding friction, it can effectively prevent the base B10 from scratching the vehicle seat. At the same time, it is convenient to push the base B10 so that the base B10 abuts against the back of the vehicle seat, and it is also convenient to connect the fastening device B300 to the vehicle seat.

[0188] Figure 32 shows a bottom perspective view of the base B10 of the carrier B1 according to one embodiment. Unlike Figure 31, the first roller B410a and the second roller B410b are removed from the base body B100.

[0189] According to this embodiment, a mounting groove B160a is provided in the middle of the transition portion B140 for mounting the first roller B410a. A rotating hole B161a is provided at each end of the mounting groove B160a. Two pivot portions B420a located at both ends of the first roller B410a can be inserted into the two rotating holes B161a respectively for rotation, thereby achieving a pivotal connection between the first roller B410a and the base body B100. Similarly, a mounting groove B160b is provided in the bottom B110 for accommodating the second roller B410b. Two pivot portions B420b at both ends of the second roller B410b are inserted into the two rotating holes B161b at both ends of the mounting groove B160b respectively, thereby achieving a pivotal connection between the second roller B410b and the base body B100.

[0190] Figure 33 shows a rear sectional view of the base B10 of the carrier B1 according to section line II in Figure 31. As can be seen from Figure 33, the first roller B410a is received in the mounting groove B160a, and pivot portions B420a are provided on both ends of the first roller B410a, which are inserted into the rotation holes B161a at both ends of the mounting groove B160a.

[0191] Figure 34 shows a rear sectional view of the base B10 of the carrier B1 according to section line II-II in Figure 32. The first roller B410a is taken out from the mounting groove B160a. It can be seen that the first roller B410a is provided with two symmetrical pivot parts B420a. It can be seen that a rotating hole B161a is provided at each end of the mounting groove B160a.

[0192] Figure 35 shows a bottom perspective view of the base B10 of a vehicle B1 according to an embodiment. Anti-friction parts B500a and B500b are also provided in the transition section B140 and the bottom B110. Specifically, the anti-friction parts B500a and B500b include multiple rolling elements, each including multiple first rollers B510a and multiple second rollers B510b, causing rolling contact between the base body B100 and the vehicle seat. The first rollers B510a are pivotally connected to the transition section B140, while the second rollers B510b are pivotally connected to the bottom B110.

[0193] In other embodiments, the multiple rolling elements are arranged as rollers and can be pivotally connected only to the bottom B110, without pivotally connecting to the transition section B130.

[0194] According to this embodiment, along the width W direction of the seat B10, two first rollers B510a are provided at intervals in the left-right direction in the transition portion B140. The two first rollers B510a can be pivotally connected to the transition portion B140 of the base body B110. Optionally, the two first rollers B510a can extend from the rear portion B120, the transition portion B140, and the bottom portion B110; that is, the first rollers B510a protrude from the surfaces of the rear portion B120, the transition portion B140, and the bottom portion B110, thereby advantageously preventing the rear portion B120 and the bottom portion B110 from scratching the backrest and seat of the vehicle seat. Optionally, the two first rollers B510a are symmetrically arranged with respect to the centerline of the base body B110 in the left-right direction. As can be seen from the above, the two first rollers B510a are located between the two fastening devices B300 in the left-right direction. Optionally, the two first rollers B510a are also located adjacent to the two fastening devices B300. In other embodiments, the number of first rollers B510a may be more than two, and the more than two first rollers B510a are spaced apart in the left-right direction at the transition portion B140.

[0195] The first roller B510a can be made of a soft material, such as TPE, silicone, rubber, or TPU. Alternatively, the first roller B510a can be made of a hard material and covered with a replaceable soft material, such as TPE, silicone, rubber, or TPU, to improve the service life of the first roller B510a and effectively prevent excessive friction between the first roller B510a and the seat of the vehicle seat.

[0196] According to this embodiment, additionally, a plurality of second rollers B510b are provided on the front and / or middle side of the bottom B110. Optionally, the second rollers B510b protrude from the surface of the bottom B110. Optionally, the second rollers B510b are located in front of the fastening device B300 in the front-back direction. Optionally, two second rollers B510b are provided on the front side of the bottom B110. Optionally or additionally, one second roller B510b is provided on the middle side of the bottom B110. Optionally, a total of three second rollers B510b are provided on the front and middle sides of the bottom B110, which is greater than the number of first rollers B510a provided in the transition section B110. The three second rollers B510b are arranged in a triangular configuration, or alternatively, in an isosceles triangle configuration. Optionally, two of the second rollers B510b are spaced apart in the left-right direction, and the remaining second roller B510b is located between the two second rollers B510b in the left-right direction. Optionally, the remaining second roller B510b is located behind the two second rollers B510b. Optionally, the two second rollers B510b spaced apart in the left-right direction are symmetrically arranged with respect to the center line of the base body B100 in the left-right direction, and the remaining second roller B510b is located on the center line of the base body B100 in the left-right direction.

[0197] The second roller B510b can be made of a soft material, such as TPE, silicone, rubber, or TPU. Alternatively, the second roller B510b can be made of a hard material and covered with a replaceable soft material, such as TPE, silicone, rubber, or TPU, to improve the service life of the first roller B510a and effectively prevent excessive friction between the second roller B510b and the seat of the vehicle. Preferably, the material of the first roller B510a and the second roller B510b is the same.

[0198] When the anti-friction parts B500a and B500b are configured as first rollers B510a and second rollers B510b, multiple first rollers B510a and second rollers B510b can be provided, such as four, to be located around the bottom B110. For example, as described above, two first rollers B510a (partially protruding from the bottom B110) are spaced apart in the left-right direction at the transition part B140, and two second rollers B510b are spaced apart in the left-right direction at the bottom B110. Of course, the first rollers B510a and second rollers B510b can also be provided solely at the bottom B110, located around its perimeter. Alternatively, at least one second roller B510b can be provided at the center of the bottom surface of the bottom B110, as described above, to ensure an appropriate number of first rollers B510a and second rollers B510b. Because it is rolling friction, the frictional force is small, thus avoiding scratches on the vehicle seats. According to this disclosure, the first roller B510a and the second roller B510b can also be bearings, balls, needle rollers, etc.

[0199] The transition section B140 is provided with a mounting groove B160a for receiving the first roller B510a, and the bottom section B110 is provided with a mounting groove B160b for receiving the second roller B510b.

[0200] Optionally, the first roller B410a, second roller B410b, first roller B510a, and second roller B510b in Figures 31 to 35 can be arbitrarily combined. For example, the first roller B410a can be provided in the transition section B140 of Figure 31, while the second roller B410b can be replaced with the second roller B510b in Figure 35, or vice versa. Alternatively, the first roller B410a in Figure 31 can be replaced with the first roller B510a in Figure 35, while the second roller B410b in Figure 31 remains unchanged. Depending on the vehicle B1 and the vehicle seat, those skilled in the art can adaptably combine the first roller B410a, second roller B410b, first roller B510a, and second roller B510b in any combination to better achieve the anti-scratch effect.

[0201] Figure 36 shows a bottom perspective view of the base B10 of the carrier B1 according to an embodiment. According to this embodiment, the anti-friction portion B700 includes an anti-friction layer B710 covering the surface of the base body B100. The anti-friction layer B710 is made of a material with a low coefficient of friction; for example, the coefficient of friction of the material of the anti-friction layer B710 is lower than that of the material of the base body B100. The material can be, for example, a glass layer or a polished metal layer. Optionally, the anti-friction portion B700, or the anti-friction layer B710, completely covers the base body B100. Optionally, the anti-friction layer B710 can cover the entire surface of the bottom B110 and rise upwards at a position corresponding to the transition portion B140, thereby covering the transition portion B140 or even at least partially covering the rear portion B120. The anti-scratch part B700 and the base body B100 can be joined together by bonding, snapping, welding, etc., to prevent the base B10 from scratching the vehicle seat, and to facilitate pushing the base B10 so that the base B10 can abut against the vehicle seat, and to allow the fastening device B300 to be connected to the vehicle seat.

[0202] The anti-scratch part B700 in Figure 36 can also be combined with other embodiments in Figures 31 to 35. Those skilled in the art can make modifications according to actual needs without departing from the scope of this application.

[0203] This disclosure advantageously solves the problem of the vehicle B1 scratching the surface of the car seat when it is installed on the car seat, and at the same time, when the vehicle B1 is against the back of the car seat or connected to the car seat by means of a fastening device, the vehicle B1 can be easily pushed, thereby saving the user's effort.
