Description

Technical Field

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

[0002] A child safety seat, also known as a Child Restraint System (CRS), is a seat specifically designed for children and installed inside vehicles such as cars to effectively improve children's safety. Typically, a child safety seat consists of a base and a carrier body mounted on the base. The carrier body can rotate and slide relative to the base, allowing it to protrude laterally when in a side-facing position, making it easy for users to put in or take out infants. However, in most current designs, this lateral protrusion creates a recessed area in the base, which may pinch the user's hands or other body parts, causing unnecessary injury. It also makes it easy for foreign objects to fall into this area, causing the carrier body to become stuck and unusable. Summary of the Invention

[0100] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0101] Referring to Figure 1, a first aspect of this application provides a vehicle A1000, which may include a vehicle body A200 and a positioning component A100 (see Figure 2) according to an embodiment of the present invention. The positioning component A100 is used to mount the vehicle body A200 onto a car seat (not shown in the figure) to improve the safety of children or infants riding in a car. It should be noted that the vehicle body A200 may be, for example, a seat, a carrier, or a sleeping box. The positioning component A100 will be described concurrently with the following description of the vehicle A1000.

[0102] Referring to Figures 2 to 4, in one embodiment, the positioning component A100 includes a first positioning component A110 and a second positioning component A120, with the first positioning component A110 rotatably disposed on the second positioning component A120. One of the first positioning component A110 and the second positioning component A120 is provided with a first track A131 and a second track A132, and the other is provided with a first slider A141 and a second slider A142. For example, as shown in Figures 3 and 4, the first positioning component A110 is provided with a first slider A141 and a second slider A142, and the second positioning component A120 is provided with a first track A131 and a second track A132. The first slider A141 and the second slider A142 are spaced apart along the front-rear direction (i.e., directions Q1 and Q2) of the first positioning component. The first track A131 extends along a first direction F1, and the second track A132 extends along a second direction F2. The first direction F1 and the second direction F2 intersect. In one embodiment, the first slider A141 slides along either the first track A131 or the second track A132, and the second slider A142 slides along the other track A131 or the second track A132. In this way, the first positioning component A110 can be displaced simultaneously with the rotation of the second positioning component A120 (see Figures 8 and 10).

[0103] In one embodiment, as shown in Figures 1 to 4, the first positioning component A110 is used to connect the vehicle body A200, and the second positioning component A120 is used to connect the vehicle seat. Specifically, the first positioning component A110 is provided with a first connecting mechanism A150 (e.g., a latching hook), which is mainly used to connect with a latching member (not shown in the figure) at the bottom of the vehicle body A200. The second positioning component A120 is provided with a seat connecting mechanism A160 (e.g., an ISOFIX connector) and a support leg A170. The seat connecting mechanism A160 is mainly used to fix the second positioning component A120 to the vehicle seat, and the support leg A170 is mainly used to rest against the floor inside the vehicle. Thus, when the positioning component A100 is installed on the vehicle seat and the vehicle body A200 is installed on the positioning component A100, the orientation of the vehicle body A200 can be changed by rotating the first positioning component A110, allowing the vehicle body A200 to have different usage modes. In some embodiments, the orientation of the vehicle body A200 depends on the extension directions of the first track A131 and the second track A132. For example, when the first track A131 extends along the first direction F1 and the second track A132 extends along the second direction F2, the vehicle body A200 has a usage mode oriented towards the first direction F1 or the second direction F2 after rotating with the first positioning component A110 relative to the second positioning component A120.

[0104] It should be noted that in this embodiment, the first positioning component A110 has a front end and a rear end. To clearly understand the various ends of the first positioning component A110, taking the vehicle body A200 mounted on the first positioning component A110 as an example, the front-back direction of the vehicle body A200 is parallel to the front-back direction of the first positioning component A110. Specifically, when an infant or child is sitting inside the vehicle body A200, the front end of the first positioning component A110 is closer to the infant's or child's feet than the rear end; conversely, the rear end of the first positioning component A110 is closer to the infant's or child's head than the front end. When the first positioning component A110 faces a certain direction, it means that the vehicle body A200 also faces the same direction; at the same time, the child sitting inside the vehicle body A200 also faces the same direction. To intuitively understand the front-back directions of the vehicle body A200 and the first positioning component A110, arrows Q1 and Q2 are used to schematically indicate the front and rear directions in the various figures, with direction Q1 being parallel and opposite to direction Q2.

[0105] It should also be noted that, in this embodiment, when the positioning component A100 (second positioning component A120) is installed on the car seat, the first direction F1 refers to the front-to-back direction of the car, and the second direction F2 refers to the left-to-right direction of the car. Specifically, the first direction F1 and the second direction F2 are perpendicular. More specifically, in this embodiment, the first direction F1 includes two directions (i.e., the front direction and the rear direction), which are parallel and opposite. Similarly, the second direction F2 also includes two directions (i.e., the left direction and the right direction), which are parallel and opposite. To facilitate the distinction between the front, rear, left, and right directions of the car, arrows F and B are used to schematically represent the front and rear directions, and arrows L and R are used to schematically represent the left and right directions, respectively. Therefore, when the first positioning component A110 is directed towards the front of the car relative to the second positioning component A120 along the first direction F1, it means that the front end of the first positioning component A110 is directed towards the F direction; when the first positioning component A110 is directed towards the rear of the car relative to the second positioning component A120 along the first direction F1, it means that the front end of the first positioning component A110 is directed towards the B direction; when the first positioning component A110 is directed towards the right side of the car relative to the second positioning component A120 along the second direction F2, it means that the front end of the first positioning component A110 is directed towards the R direction; when the first positioning component A110 is directed towards the left side of the car relative to the second positioning component A120 along the second direction F2, it means that the front end of the first positioning component A110 is directed towards the L direction.

[0106] It should be noted that the directional terms used in this application only indicate relative positional relationships and are used to make the description of the embodiments of this application clearer, and are not intended to unduly limit the scope of protection of this application.

[0107] Referring to Figure 4, in this embodiment, the intersection point of the first track A131 and the second track A132 is defined as the intersection center A133. Both the first track A131 and the second track A132 are divided by the intersection center A133 to form two track segments. For example, the first track A131 is divided by the intersection center A133 to form the first track segment A1311 and the second track segment A1312, and the second track A132 is divided by the intersection center A133 to form the third track segment A1321 and the fourth track segment A1322. Specifically, the first track segment A1311 extends from the intersection center A133 along the first direction F1 towards the front of the car, that is, the first track segment A1311 extends from the intersection center A133 along the F direction; the second track segment A1312 extends from the intersection center A133 along the first direction F1 towards the rear of the car, that is, the second track segment A1312 extends from the intersection center A133 along the B direction; the third track segment A1321 extends from the intersection center A133 along the second direction F2 towards the left side of the car, that is, the third track segment A1321 extends from the intersection center A133 along the L direction; and the fourth track segment A1322 extends from the intersection center A133 along the second direction F2 towards the right side of the car, that is, the fourth track segment A1322 extends from the intersection center A133 along the R direction.

[0108] In one embodiment, as shown in FIG3, the first positioning component A110 is generally disk-shaped, the first slider A141 is disposed at the center of the first positioning component A110, and the second slider A142 is disposed off-center. It should be noted that when the first positioning component A110 is generally disk-shaped, the center of the first positioning component A110 is its geometric center. Of course, in other embodiments, the first positioning component A110 can be other symmetrical shapes (e.g., ellipse, rectangle, etc.), and the first slider A141 can be disposed at or off-center from the geometric center of the first positioning component A110; alternatively, the first positioning component A110 can also be an asymmetrical shape.

[0109] It should be noted that, in this embodiment, as shown in Figure 2, the length of the second positioning component A120 along both the first direction F1 and the second direction F2 is greater than the diameter of the first positioning component A110. When the first positioning component A110 rotates relative to the second positioning component A120 to face the first direction F1 (e.g., the front or rear of a car), the center of the first positioning component A110 (i.e., the geometric center of the first positioning component A110) is coaxially arranged with the geometric center of the second positioning component A120, and the orthographic projection of the first positioning component A110 onto the second positioning component A120 is within the range of the second positioning component A120. In other words, when the first positioning component A110 faces the first direction F1, the lower surface of the first positioning component A110 (i.e., the surface facing the second positioning component A120) is supported by the upper surface of the second positioning component A120, and there is no suspended portion relative to the second positioning component A120.

[0110] Referring to Figures 2 to 4, in this embodiment, the first slider A141 slides along the second track A132, and the second slider A142 slides along the first track A131. When the first positioning component A110 is oriented towards the front of the car (i.e., direction F) relative to the second positioning component A120 along the first direction F1 (see Figure 2), the first slider A141 is located at the intersection center A133, and the second slider A142 is located within the second track segment A1312. When the first positioning component A110 is oriented towards the rear of the car (i.e., direction B) relative to the second positioning component A120 along the first direction F1, the first slider A141 is located at the intersection center A133, and the second slider A142 is located within the first track segment A1311. When the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2 (see Figures 8 and 10), the first positioning component A110 as a whole is displaced relative to the second positioning component A120 along the second direction F2. Specifically, the first positioning component A110 is pulled outward relative to the second positioning component A120 along the second direction F2. It should be noted that "the first positioning component A110 is pulled outward relative to the second positioning component A120 along the second direction F2" means that the first positioning component A110 shifts along the second direction F2 relative to the second positioning component A120 to be closer to the door on that side, rather than detaching from the second positioning component A120. More specifically, it means that the first positioning component A110 will move towards the side of the car seat where the second positioning component is installed, closer to that side's door. For example, if the second positioning component A120 is installed on the left-hand seat, when the first positioning component A110 is rotated to face the left, the first positioning component A110 will be closer to the left-hand door. If the second positioning component A120 is installed on the right-hand seat, when the first positioning component A110 is rotated to face the right, the first positioning component A110 will be closer to the right-hand door. If the second positioning component A120 is installed in the middle seat, when the first positioning component A110 is rotated to face either of the two side doors, the first positioning component A110 will move closer to the corresponding side door. All of the above situations are considered as the first positioning component A110 displacing outward along the second direction F2 relative to the side of the second positioning component A120. At this time, the geometric center of the first positioning component A110 displaces relative to the geometric center of the second positioning component A120 along the second direction F2. Furthermore, it should be noted that "the first positioning component A110 is pulled outward along the second direction F2 relative to the second positioning component A120" is not limited to requiring a "pulling" action to cause the first positioning component A110 to displace relative to the second positioning component A120 along the second direction F2; any action that achieves this directional displacement of the first positioning component A110 relative to the second positioning component A120 is acceptable.Specifically, when the first positioning component A110 is oriented towards the right side of the vehicle (i.e., the R direction) relative to the second positioning component A120 along the second direction F2, the first positioning component A110 is pulled out to the right relative to the second positioning component A120 (see Figure 8) to get closer to the right-side door; at this time, the second sliding member A142 is located at the intersection center A133, and the first sliding member A141 is located within the fourth track segment A1322. When the first positioning component A110 is oriented towards the left side of the vehicle (i.e., the L direction) relative to the second positioning component A120 along the second direction F2, the first positioning component A110 is pulled out to the left relative to the second positioning component A120 (see Figure 10) to get closer to the left-side door; at this time, the second sliding member A142 is located at the intersection center A133, and the first sliding member A141 is located within the third track segment A1321. This facilitates the user in taking a child out of or into the vehicle body A200 (see Figure 1).

[0111] Referring to Figure 2, in one embodiment, the positioning component A100 further includes a protective mechanism A180. The protective mechanism A180 is disposed on the second positioning component A120 and is slidable relative to the second positioning component A120, while the first positioning component A110 is rotatable relative to the protective mechanism A180. Specifically, the protective mechanism A180 is sleeved on the first positioning component A110, but the first positioning component A110 is rotatable relative to the protective mechanism A180. Furthermore, when the first positioning component A110 switches between a first direction F1 and a second direction F2 relative to the second positioning component A120, the first positioning component A110 and the protective mechanism A180 are driven to cooperate, allowing the protective mechanism A180 to move left and right along the second direction F2 on the second positioning component A120.

[0112] Referring to Figures 2 to 5, in one embodiment, two protrusions A121 are formed at intervals along the first direction F1 on the second positioning component A120, and an installation space A122 is formed between the two protrusions A121. Specifically, the first track A131 and the second track A132 are both located within the installation space A122, and the first positioning component A110 is rotatably disposed within the installation space A122, which can be considered as the first positioning component A110 being rotatably disposed on the second positioning component A120 and located between the two protrusions A121. Each protrusion A121 has a groove-shaped structure A1212 formed on the side facing the first positioning component A110. Specifically, both protrusions A121 are disposed on the upper surface of the second positioning component A120, and both protrusions A1211 are formed on both protrusions A1211, both of which protrude towards the installation space A122. In this way, a groove-shaped structure A1212 with an opening is formed between each limiting protrusion A1211 and the upper surface of the second positioning component A120.

[0113] In one embodiment, referring to Figures 2, 6 to 11, the protective mechanism A180 includes a protective shell A181. The protective shell A181 has an annular structure and surrounds the outer periphery of the first positioning component A110. The outer edge of the protective shell A181 can be inserted into the two grooved structures A1212 and can slide within the two grooved structures A1212. When the first positioning component A110 is pulled outward relative to the second positioning component A120 along the second direction F2, it can be considered that the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2, and part of the edge of the protective shell A181 is still inserted in the two grooved structures A1212 (see Figures 8, 10 and 11). In this way, the protective shell A181 can effectively block the gap between the first positioning component A110 and the protrusion A121, ensuring that the user cannot put their hand into the gap during operation, thereby effectively preventing the risk of pinching. Furthermore, when the first positioning component A110 rotates to face the second direction F2, the protective shell A181 can still be engaged within the groove structure A1212. This increases the number of support points for the first positioning component 110, so that when the first positioning component A110 rotates to the side (e.g., to the left or right), it can not only be supported by the first sliding member A141 and the second sliding member A142, but also receive additional support by the protective shell A181 being engaged within the groove structure A1212, thereby improving the stability of the first positioning component A110 when rotating to the side.

[0114] The working principle of the protective mechanism A180 will be briefly explained below with reference to Figures 2 to 5 and Figures 8 to 10.

[0115] When the first positioning component A110 rotates relative to the second positioning component A120 from the direction facing the front of the car to the right side of the car (i.e., switching from Figure 2 to Figure 8), as shown in Figures 3 and 4, the first sliding member A141 moves from the intersection center A133 to the end of the fourth track segment A1322 away from the intersection center A133, and the second sliding member A142 moves from the end of the second track segment A1312 away from the intersection center A133 towards the intersection center A133. The first positioning component A110 will rotate to the right relative to the second positioning component A120 and slide to the right at the same time, so that the first positioning component A110 is closer to the right door. The front edge of the first positioning component A110 gradually protrudes outward relative to the right edge of the second positioning component A120 (see Figure 8). Of course, in other embodiments, if the size of the second positioning component A120 is large enough, even if the first positioning component A110 rotates relative to the second positioning component A120 to face the right side of the car (i.e., the R direction), making the first positioning component A110 closer to the right door, the front edge of the first positioning component A110 will not protrude outward relative to the right edge of the second positioning component A120. Specific details depend on the actual design and are not specifically limited here. Since the protective shell A181 is fitted around the outer periphery of the first positioning component A110, and the first positioning component A110 can rotate relative to the protective shell A181, the first positioning component A110, while rotating and sliding, will push the protective shell A181 to move along the second direction F2 towards the right side of the car, allowing the outer edge A181a of the protective shell A181 extending along the second direction F2 to slide relative to the protrusion A121 within the groove structure A1212 along the second direction F2 to the right.

[0116] When the first positioning component A110 rotates relative to the second positioning component A120 from the direction facing the right side of the car towards the rear of the car (i.e., switching from Figure 8 to Figure 9), the second sliding member A142 moves from the intersection center A133 towards the end of the first track segment A1311 away from the intersection center A133, and the first sliding member A141 moves from the end of the fourth track segment A1322 away from the intersection center A133 towards the intersection center A133. The first positioning component A110 rotates rearward relative to the second positioning component A120 while sliding towards the intersection center A133, causing the first positioning component A110 to gradually return to its original position on the second positioning component A120 (see Figure 9). During this process, the first positioning component A110 rotates relative to the protective shell A181 and pushes the protective shell A181 to move along the second direction F2 towards the left side of the car, allowing the outer edge of the protective shell A181 extending along the second direction F2 to slide relative to the protrusion A121 within the groove structure A1212 along the second direction F2 to the left.

[0117] When the first positioning component A110 rotates relative to the second positioning component A120 from the direction facing the rear of the car to the left side of the car (i.e., switching from Figure 9 to Figure 10), the first sliding member A141 moves from the intersection center A133 to the end of the third track segment A1321 away from the intersection center A133, and the second sliding member A142 moves from the end of the first track segment A1311 away from the intersection center A133 towards the intersection center A133. The first positioning component A110 will rotate relative to the second positioning component A120 to face the left and slide to the left side of the second positioning component A120, so that the first positioning component A110 is closer to the left door, and the front edge of the first positioning component A110 gradually protrudes outward relative to the left edge of the second positioning component A120 (see Figures 10 and 11). Of course, in other embodiments, if the size of the second positioning component A120 is large enough, even if the first positioning component A110 rotates relative to the second positioning component A120 to face the left side of the car (i.e., the L direction), making the first positioning component A110 closer to the left door, the front edge of the first positioning component A110 will not protrude outward relative to the left edge of the second positioning component A120. Specific details depend on the actual design and are not specifically limited here. During this process, the first positioning component A110 rotates relative to the protective shell A181 and pushes the protective shell A181 to continue moving towards the left side of the car along the second direction F2, so that the outer edge of the protective shell A181 extending along the second direction F2 can continue to slide to the left relative to the protrusion A121 within the groove structure A1212 along the second direction F2.

[0118] When the first positioning component A110 rotates relative to the second positioning component A120 from the direction facing the left side of the car towards the front of the car (i.e., switching from Figure 10 to Figure 2), the second sliding member A142 moves from the intersection center A133 to the end of the second track segment A1312 away from the intersection center A133, and the first sliding member A141 moves from the end of the third track segment A1321 away from the intersection center A133 towards the intersection center A133. The first positioning component A110 rotates relative to the second positioning component A120 while sliding towards the intersection center A133, causing the first positioning component A110 to gradually return to its original position on the second positioning component A120 (see Figure 2). During this process, the first positioning component A110 rotates relative to the protective shell A181 and pushes the protective shell A181 to move along the second direction F2 towards the right side of the car, allowing the outer edge of the protective shell A181 extending along the second direction F2 to slide relative to the protrusion A121 within the groove structure A1212 along the second direction F2 to the right.

[0119] Referring to Figures 7, 12, and 13, in one embodiment, the protective shell A181 has a retaining recess A1811, and the outer edge of the first positioning component A110 is inserted into the retaining recess A1811. Thus, when the first positioning component A110 rotates relative to the protective shell A181, the retaining recess A1811 can prevent the first positioning component A110 from disengaging from the protective shell A181, improving the stability of the protective mechanism A180 mounted on the first positioning component A110. Furthermore, when the vehicle body A200 is mounted on the first positioning component A110, the center of gravity of the vehicle body A200 is generally biased towards the rear side of the vehicle body A200, that is, the side of the vehicle body A200 closer to its backrest. Therefore, the front side of the vehicle body A200 tends to tilt upwards. Since the vehicle body A200 is connected to the first positioning component A110, the outer edge of the first positioning component A110 is limited to the holding recess A1811, and the outer edge of the protective shell A181 is inserted into the two groove structures A1212, the reliability of the first positioning component A110 rotating and moving on the second positioning component A120 is improved.

[0120] Referring to Figures 6, 7, and 12, in one embodiment, the protective shell A181 includes a cover A1812 and a first limiting piece A1813. The cover A1812 surrounds the outer periphery of the first positioning component A110, and its outer edge extending along the second direction F2 is slidably disposed within two groove-shaped structures A1212. The first limiting piece A1813 is disposed on one side of the cover A1812 (i.e., the side facing away from the second positioning component A120) and forms an angle with the inner ring wall A18121 of the cover A1812. The first limiting piece A1813 and the inner ring wall A18121 of the cover A1812 form a retaining recess A1811, the bottom wall of which is the inner ring wall A18121 of the cover A1812. When the first positioning component A110 pushes the protective shell A181 to move along the second direction F2, it can be regarded as the first positioning component A110 pushing against the inner ring wall A18121 of the cover A1812, so that the protective shell A181 moves to the left or right along the second direction F2.

[0121] In one embodiment, the shape of the inner ring wall A18121 of the cover A1812 matches the outer contour shape of the first positioning component A110. For example, when the first positioning component A110 has a disc-shaped structure, the inner ring wall A18121 can have a circular shape, and the diameter of the inner ring wall A18121 is greater than or equal to the diameter of the first positioning component A110. Specifically, as shown in Figures 2, 6, and 7, the outer contour of the cover A1812 matches the shape of the second positioning component A120. When the first positioning component A110 is oriented towards the front of the car relative to the second positioning component A120, the projection of the cover A1812 onto the second positioning component A120 is located within the second positioning component A120. For example, the cover A1812 is approximately square in shape, and a central hole is provided on the cover A1812. The central hole has a circular shape, and the wall of the central hole is the inner ring wall A18121 of the cover A1812. More specifically, the center of the central hole is coaxially aligned with the center point of the cover A1812. The side length W1 of the cover A1812 along the first direction F1 is greater than the distance L1 between the two protrusions A121 (see Figures 5 and 6), while the side length W1 of the cover A1812 along the first direction F1 is less than or equal to the distance L3 between the bottom walls of the two groove structures A1212. The side length W2 of the cover A1812 along the second direction F2 is less than or equal to the length L2 of the second positioning component A120 along the second direction F2 (see Figure 2). Thus, when the first positioning component A110 moves the cover A1812 along the second direction F2, it can be ensured that part of the edge of the cover A1812 can still be inserted into the groove structure A1212 of the protrusion A121. Specifically, in this embodiment, as shown in Figures 6 and 7, the diameter of the central hole on the cover A1812 is slightly smaller than the side length of the cover A1812. Thus, the inner ring wall A18121 and the outer ring wall A18122 of the cover A1812 are tangent to each other along the first direction F1, forming two first tangent portions A1812a; the inner ring wall A18121 and the outer ring wall A18122 of the cover A1812 are tangent to each other along the second direction F2, forming two second tangent portions A1812b; and four blocking portions A1812c are formed at the four corners of the cover A1812. When the first positioning component A110 rotates to face the first direction F1, the two first tangent portions A1812a are respectively engaged in the two groove structures A1212; when the first positioning component A110 rotates to face the second direction F2, the blocking portion A1812c is engaged in the groove structure A1212 and can block the gap between the first positioning component A110 and the protrusion A121.

[0122] It should be noted that when the cover A1812 has a square structure, W1 is equal to W2; of course, in other embodiments, when the cover A1812 has a rectangular structure, W1 can be greater than or less than W2.

[0123] Referring to Figures 6 and 7, in one embodiment, two first limiting pieces A1813 are provided, each of which has an arc-shaped structure. The two first limiting pieces A1813 are arranged circumferentially opposite each other around the inner annular wall A18121 of the cover body A1812. Of course, in other embodiments, there may be one first limiting piece A1813 in a ring shape; or, at least three first limiting pieces A1813 may be provided, with the three first limiting pieces A1813 spaced apart along the circumferential direction of the inner annular wall A18121 of the cover body A1812. Specifically, the number and shape of the first limiting pieces A1813 are not specifically limited here.

[0124] In one embodiment, as shown in Figures 12 and 13, the first limiting piece A1813 is integrally formed on the cover A1812; in other words, the cover A1812 and the first limiting piece A1813 are an integrally formed structure. Of course, in other embodiments, the first limiting piece A1813 can be connected to the cover A1812 by means of bonding, riveting, or other methods.

[0125] Referring to Figures 7 and 12, in one embodiment, the protective shell A181 further includes a second limiting piece A1814. The second limiting piece A1814 is disposed on the other side of the cover A1812 (i.e., the side facing the second positioning component A120) and is angled to the inner annular wall A18121 of the cover A1812. The first limiting piece A1813, the inner annular wall A18121 of the cover A1812, and the second limiting piece A1814 sequentially surround to form a retaining recess A1811.

[0126] In one embodiment, the second limiting piece A1814 can be integrally formed on the cover A1812. Alternatively, in other embodiments, the second limiting piece A1814 can be connected to the cover A1812 by means of bonding, riveting, or other methods. Specifically, as shown in FIG13, the protective mechanism A180 also includes a connector (not shown in the figure). The cover A1812 is provided with a first connecting portion A1812e, and the second limiting piece A1814 is provided with a second connecting portion A18141. The connector connects the first connecting portion A1812e and the second connecting portion A18141. Both the first connecting portion A1812e and the second connecting portion A18141 are provided with connecting holes. The connector can be a screw or bolt, etc., so that the connector can pass through the two connecting holes and be threaded together to prevent the second limiting piece A1814 from detaching from the cover A1812. In one embodiment, multiple second limiting pieces A1814 are provided, and the multiple second limiting pieces A1814 are spaced apart along the circumferential direction of the inner ring wall A18121. Specifically, in this embodiment, four second limiting pieces A1814 are provided, and the four second limiting pieces A1814 are respectively located at the four corners of the cover A1812, which has a square structure (see Figure 7). Of course, in other embodiments, the second limiting pieces A1814 can be annular structures, and the center of the second limiting piece A1814 is coaxially arranged with the center of the inner ring wall A18121 of the cover A1812.

[0127] Referring to Figures 5 to 7, in one embodiment, a locking tongue A190 is movably disposed within each groove-shaped structure A1212. The two first tangent portions A1812a of the protective shell A181 are respectively provided with first locking holes A1815, and the front and rear ends of the first positioning component A110 are respectively provided with second locking holes (not shown in the figures). When the first positioning component A110 rotates to face the first direction F1, at least one locking tongue A190 can pass through the corresponding first locking hole A1815 and the second locking hole, thereby achieving locking of the first positioning component A110 when facing the first direction F1.

[0128] In the aforementioned positioning component A100, the first positioning component A110 is rotatably mounted on the second positioning component A120. When the first positioning component A110 rotates relative to the second positioning component A120 to face the second direction F2, the first positioning component A110 can be pulled outward relative to the second positioning component A120 along the second direction F2. Therefore, when the carrier body A200 is mounted on the first positioning component A110 and the carrier body A200 faces the second direction F2 along with the first positioning component A110, the carrier body A200 will be pulled outward along the second direction F2, which makes it convenient for the user to carry the infant in or out. Furthermore, in the aforementioned positioning component A100, the first positioning component A110 is located between the two protrusions A121 on the second positioning component A120. When the first positioning component A110 is pulled outward relative to the second positioning component A120 along the second direction F2, part of the edge of the protective shell A181 is still inserted into the two groove structures A1212. In this way, the protective shell A181 can effectively cover the gap between the first positioning component A110 and the protrusions A121, ensuring that the user cannot put their hand into the gap during operation, thereby effectively preventing the risk of pinching. At the same time, the number of support points of the first positioning component A110 is increased, so that when the first positioning component A110 is rotated to the side (e.g., to the left or right), it can not only be supported by the first sliding member A141 and the second sliding member A142, but also receive additional support by the protective shell A181 being engaged in the groove structure A1212, thereby improving the stability of the first positioning component A110 when it is rotated to the side.

[0129] A second aspect of this application provides a vehicle, including a vehicle body B300 (see FIG26) and a positioning component B100 according to some embodiments of the present invention. The vehicle body B300 may be, for example, a seat, a basket, or a sleeping box, etc. The vehicle body B300 and the positioning component B100 will be described in conjunction with the following description of the vehicle.

[0130] Figures 14 and 15 show perspective views of a positioning component B100 according to an embodiment of a second aspect of this application. The positioning component B100 is used to mount a vehicle body B300 (see Figure 26) onto a car seat (not shown) to ensure safe travel for children or infants. Specifically, the positioning component B100 may include a first positioning component B110 and a second positioning component B120. The first positioning component B110 and the second positioning component B120 will be described in detail below.

[0131] In one embodiment, the second positioning component B120 is provided with a track, and the first positioning component B110 is provided with a slider. The slider slides along the track to allow the first positioning component B110 to rotate and slide relative to the second positioning component B120. Specifically, as shown in Figures 15 and 16, the track includes a first track B131 and a second track B132. The first track B131 extends along a first direction F1, and the second track B132 extends along a second direction F2, which intersects with the first direction F1. The slider includes a first slider B141 and a second slider B142 spaced apart along the front-back directions (i.e., Q1 and Q2 directions) of the first positioning component B110 (see Figures 23 and 24; the specific structure is described below). The first slider B141 slides along either the first track B131 or the second track B132, and the second slider B142 slides along the other of the first track B131 or the second track B132. For example, the first slider B141 slides along the first track B131, and the second slider B142 slides along the second track B132. Alternatively, the first slider B141 slides along the second track B132, and the second slider B142 slides along the first track B131. In this way, the first positioning component B110 can be displaced simultaneously with the rotation of the second positioning component B120.

[0132] Referring to Figures 14 and 15, in one embodiment, the first positioning component B110 is used to connect the vehicle body B300, and the second positioning component B120 is used to connect the vehicle seat. Specifically, the first positioning component B110 is provided with a first connecting mechanism B170 (details below), which is used to connect with the engaging member B310 (see Figure 26) at the bottom of the vehicle body B300. The second positioning component B120 is provided with a seat connecting mechanism B180 (such as an ISOFIX connector) and a support leg B190. The seat connecting mechanism B180 is mainly used to fix the second positioning component B120 to the vehicle seat, and the support leg B190 is mainly used to abut against the floor inside the vehicle. Thus, when the positioning component B100 is installed on the vehicle seat and the vehicle body B300 is installed on the positioning component B100, the orientation of the vehicle body B300 can be changed by rotating the first positioning component B110, allowing the vehicle body B300 to have different usage modes. It should be noted that the orientation of the vehicle body B300 depends on the extension directions of the first track B131 and the second track B132. When the first track B131 extends along the first direction F1 and the second track B132 extends along the second direction F2, the vehicle body B300 has a usage mode oriented towards the first direction F1 and the second direction F2. Specifically, when the first direction F1 and the second direction F2 are perpendicular, it can be considered that the first track B131 and the second track B132 are perpendicular. The intersection point of the first track B131 and the second track B132 is called the intersection center B133 (see Figure 16).

[0133] In one embodiment, the first positioning component B110 is generally disk-shaped, the first slider B141 is located at the center of the first positioning component B110, and the second slider B142 is located off-center. It should be noted that when the first positioning component B110 is generally disk-shaped, the center of the first positioning component B110 is its geometric center. Of course, in other embodiments, the first positioning component B110 can be other symmetrical shapes (e.g., ellipse, rectangle, etc.), and the first slider B141 can be located at or off-center from the geometric center of the first positioning component B110; alternatively, the first positioning component B110 can also be asymmetrical. In this embodiment, the first slider B141 slides along the second track B132, and the second slider B142 slides along the first track B131. When the first positioning component B110 rotates relative to the second positioning component B120 to face the first direction F1, the vehicle body B300 is in the usage mode facing the first direction F1. At this time, the first slider B141 is located at the intersection center B133, and the second slider B142 is located at the first track B131. This can be understood as the center of the first positioning component B110 (i.e., the geometric center of the first positioning component B110) being coaxial with the geometric center of the second positioning component B120. When the first positioning component B110 rotates relative to the second positioning component B120 to face the second direction F2, the vehicle body B300 is in the usage mode facing the second direction F2. At this time, the second slider B142 is located at the intersection center B133, the first slider B141 is located at the second track B132, and the first positioning component B110 as a whole is displaced relative to the second positioning component B120 along the second direction F2. Specifically, the first positioning component B110 is pulled outward relative to the second positioning component B120 along the second direction F2. It should be noted that "the first positioning component B110 is pulled outward relative to the second positioning component B120 along the second direction F2" means that the first positioning component B110 shifts along the second direction F2 relative to the second positioning component B120 to be closer to the door on that side, rather than detaching from the second positioning component B120. Specifically, it means that the first positioning component B110 will move towards the side of the car seat where the second positioning component is installed, closer to the door on that side. For example, if the second positioning component B120 is installed on the left seat, when the first positioning component B110 is rotated to face the left, the first positioning component B110 will be closer to the left door. If the second positioning component B120 is installed on the right seat, when the first positioning component B110 is rotated to face the right, the first positioning component B110 will be closer to the right door. If the second positioning component B120 is installed on the middle seat, when the first positioning component B110 is rotated to face either of the two doors, the first positioning component B110 will be closer to the corresponding door.All of the above situations are considered as the first positioning component B110 displacing outward along the second direction F2 relative to one side of the second positioning component B120. At this time, the geometric center of the first positioning component B110 displaces relative to the geometric center of the second positioning component B120 along the second direction F2. Furthermore, it should be noted that "the first positioning component B110 pulling outward relative to the second positioning component B120 along the second direction F2" is not limited to a "pulling" action to cause the first positioning component B110 to displace relative to the second positioning component B120 along the second direction F2; any action that achieves this directional displacement of the first positioning component B110 relative to the second positioning component B120 is acceptable. This facilitates the user in taking a child out of or into the vehicle body B300.

[0134] It should be noted that in this embodiment, the first positioning component B110 has a front end and a rear end. To clearly understand the various ends of the first positioning component B110, taking the vehicle body B300 mounted on the first positioning component B110 as an example, the front-back direction of the vehicle body B300 is parallel to the front-back direction of the first positioning component B110. Specifically, when an infant or child is sitting inside the vehicle body B300, the front end of the first positioning component B110 is closer to the infant's or child's feet than the rear end, and conversely, the rear end of the first positioning component B110 is closer to the infant's or child's head than the front end. When the first positioning component B110 faces a certain direction, it means that the vehicle body B300 also faces the same direction; at the same time, the child sitting inside the vehicle body B300 also faces the same direction. To intuitively understand the front-back direction of the vehicle body B300 and the first positioning component B110, arrows Q1 and Q2 are used to schematically indicate the front and rear directions in each figure, with direction Q1 being parallel and opposite to direction Q2.

[0135] It should also be noted that, in this embodiment, when the positioning component B100 (second positioning component B120) is installed on the car seat, the first direction F1 refers to the front-to-back direction of the car, and the second direction F2 refers to the left-to-right direction of the car. More specifically, in this embodiment, the first direction F1 includes two directions (i.e., the front direction and the rear direction), which are parallel and opposite. Similarly, the second direction F2 also includes two directions (i.e., the left direction and the right direction), which are parallel and opposite. To facilitate the distinction between the front, rear, left, and right directions of the car, arrows F and B are used to schematically represent the front and rear directions, and arrows L and R are used to schematically represent the left and right directions, respectively. Therefore, the rotation of the first positioning component B110 relative to the second positioning component B120 towards the first direction F1 mentioned above means that the front end of the first positioning component B110 is facing the first direction F1 (which can mean facing the F direction or the B direction); the rotation of the first positioning component B110 relative to the second positioning component B120 towards the second direction F2 means that the front end of the first positioning component B110 is facing the second direction F2 (which can mean facing the R direction or the L direction).

[0136] It should be noted that the directional terms used in this application only indicate relative positional relationships and are used to make the description of the embodiments of this application clearer, and are not intended to unduly limit the scope of protection of this application.

[0137] In one embodiment, both the first track B131 and the second track B132 are divided into two segments by the intersection center B133. For example, the first track B131 is divided by the intersection center B133 to form a first track segment B1311 and a second track segment B1312, and the second track B132 is divided by the intersection center B133 to form a third track segment B1321 and a fourth track segment B1322 (see Figure 16). Specifically, the first track segment B1311 extends from the intersection center B133 along the first direction F1 towards the front of the vehicle, i.e., the first track segment B1311 extends from the intersection center B133 along the first direction F1 towards the rear of the vehicle, i.e., the second track segment B1312 extends from the intersection center B133 along the first direction F1 towards the rear of the vehicle, i.e., the second track segment B1312 extends from the intersection center B133 along the intersection center B133 along the second direction F2 towards the left side of the vehicle, i.e., the third track segment B1321 extends from the intersection center B133 along the intersection center B133 along the intersection center B133 along the second direction F2 towards the right side of the vehicle, i.e., the fourth track segment B1322 extends from the intersection center B133 along the intersection center B133 along the intersection center B133 along the second direction F2 towards the right side of the vehicle, i.e., the fourth track segment B1322 extends from the intersection center B133 along the intersection center B133 along the intersection center B133. Thus, after the vehicle body B300 rotates relative to the second positioning component B120 with the first positioning component B110, it has four usage modes: forward, backward, left, and right.

[0138] Referring to Figures 16 and 17, in one embodiment, the second positioning component B120 includes a top cover B121 and a bottom cover B122, which are connected vertically to form a second mounting cavity B123. A first track B131 and a second track B132 are both disposed on the top cover B121 and communicate with the second mounting cavity B123. In one embodiment, the upper surface of the top cover B121 has two protrusions spaced apart along a first direction F1. These two protrusions can be referred to as a first protrusion B124 and a second protrusion B125, respectively. A mounting space B126 is formed between the first protrusion B124 and the second protrusion B125. The first track B131 and the second track B132 are both located within the mounting space B126, and the first positioning component B110 is rotatably disposed within the mounting space B126. Specifically, when the second positioning component B120 is installed on the car seat, the first protrusion B124 is closer to the front of the car than the second protrusion B125, which can be considered as the first protrusion B124 being located in front of the second protrusion B125 along the car's driving direction. More specifically, as shown in Figures 16 and 18, both the first protrusion B124 and the second protrusion B125 have limiting protrusions B127, and the limiting protrusions B127 protrude towards the mounting space B126. The limiting protrusions B127 on both the first protrusion B124 and the second protrusion B125 form an open groove structure B270 with the upper surface of the second positioning component B120 (i.e., the upper surface of the top cover B121). Thus, when the first positioning component B110 is housed within the mounting space B126 and oriented towards the first direction F1, a portion of the circumferential edge of the first positioning component B110 can be inserted into the two slotted structures B270 (compare Figures 14 and 15). In this way, the slotted structures B270 can restrict the swaying of the first positioning component B110 and the vehicle body B300 in the approximately vertical direction (i.e., the direction perpendicular to the plane containing the first direction F1 and the second direction F2), while allowing the first positioning component B110 to rotate and slide in the horizontal direction (i.e., the plane containing the first direction F1 and the second direction F2). When a collision or emergency braking occurs, the vehicle body B300, under the action of inertial force, tends to tilt forward (i.e., towards the front of the vehicle), thereby causing the first positioning component B110 to tend to detach from the second positioning component B120. By inserting a portion of the circumferential edge of the first positioning component B110 into the two slotted structures B270, the slotted structures B270 can press against the first positioning component B110, thereby preventing the vehicle body B300 and the first positioning component B110 from detaching from the second positioning component B120, thus improving the safety of the vehicle.

[0139] Referring to Figures 19 to 22, in one embodiment, a clearance recess B210 is formed on the first positioning component B110. The first positioning component B110 can avoid interference with the first protrusion B124 and the second protrusion B125 during rotation relative to the second positioning component B120 within the mounting space B126 by means of the clearance recess B210. Specifically, when the first positioning component B110 rotates relative to the second positioning component B120 to face the first direction F1, the bottom of the clearance recess B210 can be inserted into the groove structure B270, and a gap is left between the sidewall of the clearance recess B210 and the limiting protrusion B217 of the first protrusion B124. Specifically, the first positioning component B110 may include a support base B111 and a connecting seat B112. The support base B111 is generally disc-shaped, and the connecting seat B112 is roughly strip-shaped. The connecting seat B112 protrudes from the upper surface of the support base B111. When the first positioning component B110 rotates to face the first direction F1, the connecting seat B112 can be regarded as extending along the first direction F1. When the first positioning component B110 rotates to face the second direction F2, the connecting seat B112 can be regarded as extending along the second direction F2. The center of the support base B111 is approximately coaxial with the geometric center of the connector B112, and the diameter of the support base B111 is greater than the length of the connector B112. The protruding part of the support base B111 relative to the connector B112 along the length of the connector B112 can be regarded as the bottom of the aforementioned avoidance recess B210, and can also be regarded as the edge of the first positioning component B110 that can be inserted into the slot structure 270. The side wall of the connector B112 facing its extension direction can be regarded as the side wall of the avoidance recess B210. More specifically, when the first positioning component B110 is rotated relative to the second positioning component B120 to face the first direction F1, the distance M2 (see Figure 22) between the sidewall of the recess B210 and the limiting protrusion B127 of the first protrusion B124 is not less than 10mm, for example, M2 is 10mm, 11mm, 12mm, 13mm, etc.; or, the distance M2 between the sidewall of the recess B210 and the limiting protrusion B127 of the first protrusion B124 is not greater than 5mm, for example, M2 is 5mm, 4mm, 2mm, etc. In this way, when the user rotates the first positioning component B110 relative to the second positioning component B120 to face forward or backward, the space between the first positioning component B110 and the limiting protrusion B127 of the first protrusion B124 can be avoided from pinching and injuring the user's hands or other parts, thus improving the safety of using the positioning component B100.

[0140] Referring to Figures 23 to 26, in one embodiment, the first connecting mechanism B170 is disposed on the first positioning component B110 and has a locked state and an unlocked state. Specifically, the first connecting mechanism B170 is disposed on the connecting seat B112. When the first connecting mechanism B170 is in the locked state, the first connecting mechanism B170 is connected to the vehicle body B300. When the first connecting mechanism B170 is in the unlocked state, the first connecting mechanism B170 is disassembled from the vehicle body B300. Specifically, the bottom of the vehicle body B300 is provided with a locking member B310 (such as a locking rod, see Figure 26). The first connecting mechanism B170 includes a locking hook B171 and a locking groove B1121 disposed on the connecting seat B112. The locking groove B1121 is used to accommodate the locking member B310 at the bottom of the vehicle body B300. The locking hook B171 is pivotally connected to the connecting seat B112 and has a locked position and an unlocked position. When the engaging hook B171 is in the locked position, it at least partially extends into the slot B1121 to engage and lock with the engaging member B310 of the carrier body B300. More specifically, the first positioning assembly B110 has a first mounting cavity B113, and the slot wall of the slot B1121 has a through hole B1122 (see Figure 20), which connects the first mounting cavity B113 and the slot B1121. As shown in Figures 27 and 28, the first mounting cavity B113 has a support frame B114, and the engaging hook B171 is pivotally connected to the support frame B114 by a pivot shaft B115. When the engaging hook B171 is in the locked position, it at least partially passes through the through hole B1122 and extends into the slot B1121 (see Figures 23 and 24) to engage and lock with the engaging member B310. When the locking hook B171 is in the unlocked position, the locking hook B171 retracts from the slot B1121 through the through hole B1122 (see Figure 25).

[0141] In this embodiment, as shown in Figures 19, 20, and 26, the bottom of the vehicle body B300 typically has two engaging members B310 along the front-to-back direction, and the connecting seat B112 has two rows of slots B1121. Each row of slots B1121 includes at least one slot B1121. Specifically, as shown in Figures 19 and 20, each row of slots B1121 includes two slots B1121. In other words, the first positioning component B110 has four slots B1121 formed, arranged in a rectangular pattern, and the distance between the two rows of slots B1121 along the front-to-back direction is equal to the distance between the two engaging members B310 at the bottom of the vehicle body B300. Correspondingly, the first positioning component B110 is pivotally connected to four engaging hooks B171, with each slot B1121 corresponding to one engaging hook B171.

[0142] Referring to Figures 17 to 19, in one embodiment, the positioning component B100 further includes a locking and retaining mechanism B230. The locking and retaining mechanism B230 is movably disposed on the first positioning component B110 and is used to maintain the connection between the first connecting mechanism B170 and the carrier body B300. Specifically, the locking and retaining mechanism B230 is movably disposed within the first mounting cavity B113, and when the engaging hook B171 is driven to the locked position, the locking and retaining mechanism B230 is used to lock the engaging hook B171 in the locked position.

[0143] Referring again to Figures 17 to 19, in one embodiment, the locking and retaining mechanism B230 includes a first locking member B231. The first locking member B231 is movably disposed within the first mounting cavity B113 and has a first position and a second position. Specifically, when the first positioning component B110 faces the first direction F1, the movement direction of the first locking member B231 is parallel to the first direction F1; when the first positioning component B110 faces the second direction F2, the movement direction of the first locking member B231 is parallel to the second direction F2. The first locking member B231 moves approximately horizontally. When the first locking member B231 is in the first position, the first connecting mechanism B170 is in a locked state; when the first locking member B231 is in the second position, the first connecting mechanism B170 is in an unlocked state. In one embodiment, one of the first locking member B231 and the engaging hook B171 has a locking groove B2311, and the other has an engaging portion B1711. Specifically, as shown in Figure 23, in this embodiment, the engaging hook B171 has an engaging portion B1711, and the first locking member B231 has a locking groove B2311. More specifically, when the first locking member B231 is in the first position, the engaging portion B1711 engages with the locking groove B2311 to lock the engaging hook B171 in the locked position (see Figures 23 and 24), thus placing the first connecting mechanism B170 in a locked state. When the first locking member B231 is in the second position, the engaging portion B1711 separates from the locking groove B2311 to allow the engaging hook B171 to switch between the locked and unlocked positions, thus placing the first connecting mechanism B170 in an unlocked state. It should be noted that, in this embodiment, as shown in Figures 23 and 28, the first locking member B231 is provided with four locking grooves B2311, each locking groove B2311 being used to engage with the engaging part B1711 of each engaging hook B171 for locking.

[0144] Referring to Figures 27 and 28, in one embodiment, the locking and retaining mechanism B230 further includes a third reset member B232, which provides an elastic reset force to the first locking member B231 to hold the first locking member B231 in a first position. The third reset member B232 is, for example, a spring. Thus, as shown in Figures 23 to 25, when the engaging hook B171 pivots from the unlocked position to the locked position, the third reset member B232 causes the first locking member B231 to automatically switch to the first position, allowing the locking groove B2311 of the first locking member B231 to engage with the engaging portion B1711 of the engaging hook B171 to lock the engaging hook B171 and hold it in the locked position. This improves the stability and reliability of the carrier body B300 mounted on the first positioning assembly B110.

[0145] In one embodiment, the first connecting mechanism B170 further includes a second reset member (not shown in the figure), which is used to hold the engaging hook B171 in the unlocked position. The second reset member is, for example, a torsion spring, which is sleeved on the pivot B115 and abuts against the engaging hook B171. In this way, when the first locking member B231 moves to the second position, the engaging hook B171 can automatically rotate around the pivot B115 to be in the unlocked position, thereby facilitating smooth unlocking and reducing the risk of the engaging hook B171 locking up.

[0146] Referring to Figures 24, 25, and 30, in one embodiment, the positioning component B100 further includes a first unlocking member B240 movably disposed on the first positioning component B110 to facilitate user operation of the first locking member B231. The first unlocking member B240 is driven to engage with the first locking member B231. The first unlocking member B240 can be operated to drive the first locking member B231 to move from a first position to a second position. Thus, the user can switch the first locking member B231 from the first position to the second position by operating the first unlocking member B240. Specifically, the first unlocking member B240 is provided with a driving ramp B241, which extends obliquely along the moving direction of the first unlocking member B240. The first locking member B231 is also provided with a driving part B2312, which is adapted to be pushed against and slide along the driving ramp B241, so that the first locking member B231 can switch between the first position and the second position. More specifically, the first unlocking member B240 can move up and down in a generally vertical direction on the first positioning component B110, and the direction of movement of the first unlocking member B240 intersects with the first locking member B231. Optionally, the direction of movement of the first unlocking member B240 is perpendicular to the direction of movement of the first locking member B231.

[0147] Referring to Figures 24 and 25, the cooperation relationship between the first unlocking member B240 and the first locking member B231 is briefly explained. Specifically, when the first locking member B231 is in the first position, the driving part B2312 of the first locking member B231 abuts against the top end of the driving slope B241 of the first unlocking member B240. When the first unlocking member B240 is pushed upward in the vertical direction, under the guiding drive of the driving slope B241, the relative position of the driving part B2312 on the driving slope B241 gradually changes from the top end of the driving slope B241 to the bottom end of the driving slope B241, thereby causing the first locking member B231 to move from the first position to the second position, so that the engaging part B1711 can disengage from the locking groove B2311.

[0148] Referring to Figures 24, 25, 28, and 29, in one embodiment, the positioning component B100 further includes a second unlocking member B250, which is movably disposed on the first positioning component B110 and has an unlocked position and a locked position. The second unlocking member B250 also engages with the first locking member B231. When the second unlocking member B250 is in the locked position, the first locking member B231 is in a first position. When the second unlocking member B250 is in the unlocked position, the first locking member B231 is in a second position. Thus, the user can also control the position of the first locking member B231 by operating the second unlocking member B250. It should be noted that in this embodiment, the movement direction of the second unlocking member B250 is parallel to the movement direction of the first locking member B231. When the first positioning component B110 is oriented toward the first direction F1, the movement direction of the second release component B250 is parallel to the first direction F1; when the first positioning component B110 is oriented toward the second direction F2, the movement direction of the second release component B250 is parallel to the second direction F2.

[0149] Referring to Figures 28 to 32, in one embodiment, the second unlocking member B250 is provided with a pushing portion B251, and the first locking member B231 is also provided with a pushing portion B2313. The pushing portion B251 and the pushing portion B2313 are driven to cooperate, and the second operating member B250 can be operated to drive the first locking member B231 to switch from a first position to a second position. Specifically, one of the pushing portion B251 and the pushing portion B2313 can be a recess and the other can be a protrusion, and the two are inserted to drive to cooperate. For example, in this embodiment, the pushing portion B251 includes a pushing recess B2511, which extends toward the pushing portion B2313 and along the moving direction of the second unlocking member B250, and the pushing portion B2313 is movably inserted into the pushing recess B2511. When the second release member B250 is operated and moves from the locked position to the unlocked position, the second release member B250 drives the push part B2313 to move by pushing the rear side wall B2511a of the recess B2511, thereby causing the first locking member B231 to switch from the first position to the second position.

[0150] In one embodiment, as shown in Figures 29 and 32, the second release member B250 is further provided with a guide groove B252, which extends along the moving direction of the second release member B250. A guide post B116 is provided in the first mounting cavity B113, and the guide post B116 is inserted into the guide groove B252. Through the guiding engagement of the guide post B116 and the guide groove B252, deviation of the second release member B250 during movement can be avoided. In this embodiment, there are two guide grooves B252, distributed on the left and right sides of the second release member B250. There are also two guide posts B116, each guidingly engaging with its corresponding guide groove B252. Furthermore, each guide groove B252 is provided with an elastic member B254, which mainly provides elastic restoring force to the second release member B250, so that the second release member B250 remains in the locked position.

[0151] As shown in Figures 24, 25, and 29, in one embodiment, the second release member B250 is provided with a gripping recess B253. Thus, when a user needs to operate (e.g., pull) the second release member B250, they can place their fingers into the gripping recess B253 to quickly pull the second release member B250 to move it.

[0152] Referring to Figures 15, 23, 29, and 32, taking the first positioning component B110 facing the right side of the vehicle (i.e., the R direction) along the second direction F2 as an example, the cooperation relationship between the second unlocking component B250 and the first locking component B231 is briefly explained. Specifically, when the first locking component B231 is in the first position, the pushing portion B2313 of the first locking component B231 abuts against the rear side wall B2511a of the pushing recess B2511 of the second unlocking component B250 (see Figure 29). When the second release member B250 is pulled to the right along the second direction F2, the rear side wall B2511a of the pushing recess B2511 of the second release member B250 pushes the pushing part B2313 of the first locking member B231, thereby pushing the pushing part B2313 to the right along the second direction F2, and thus causing the first locking member B231 to move to the second position, so that the engaging part B1711 can disengage from the locking groove B2311.

[0153] In one embodiment, the first releasing member B240 and the second releasing member B250 are disposed opposite to each other along the circumferential direction of the first positioning component B110 (see Figures 19 and 20). Specifically, the first releasing member B240 and the second releasing member B250 are disposed opposite to each other along the moving direction of the first locking member B231 (see Figures 27 and 28). In this embodiment, the second releasing member B250 is located near the front row engaging hook B171 (or slot B1121), and the first releasing member B240 is located near the rear row engaging hook B171 (or slot B1121). Specifically, the first releasing member B240 is located at the rear end in the extending direction of the connecting seat B112, that is, the first releasing member B240 can be regarded as being located at the rear end of the first positioning component B110, and more specifically, the first releasing member B240 is located near the avoidance recess B210. The second release member B250 is located at the front end of the connecting seat B112 in the extending direction, that is, the second release member B250 can be regarded as being located at the front end of the first positioning component B110. Both the first release member B240 and the second release member B250 are driven to cooperate with the first locking member B231. Thus, as shown in Figure 15, when the vehicle body 300 (such as a basket, see Figure 26) rotates relative to the second positioning component B120 towards the second direction F2, that is, when the first positioning component B110 rotates to the side (left or right direction) relative to the second positioning component B120, the second releasing member B250 is pulled outward in the second direction F2 along with the first positioning component B110 relative to the second positioning component B120, so as to protrude to the side (i.e., left or right) to be closer to the side door and face the user, so as to facilitate user operation. The user can control the state of the first connecting mechanism B170 by the second releasing member B250 located at the front end of the first positioning component B110; in other words, the user can control the position of the locking hook B171 by the second releasing member B250 so as to remove the vehicle body B300 from the first positioning component B110. In one embodiment, when the first positioning component B110 rotates relative to the second positioning component B120 toward the second direction F2, that is, when the front end of the first positioning component B110 faces the second direction F2, since the second releasing member B250 is located at the front end of the first positioning component B110, the second releasing member B250 is pulled outward along with the first positioning component B110 relative to the second positioning component B120 in the second direction F2, so that the second releasing member B250 is in a position closer to the side door. In this way, during the process of disassembling the vehicle body B300 in a side position, the user does not need to operate the first releasing member B240 located at the rear and further away to release the lock, but can directly operate the second releasing member B250 located at the front. This makes it more convenient and faster for the user to disassemble the vehicle body B300.It should be noted that since the second unlocking component B250 is mounted on the first positioning component B110, when the first positioning component B110 rotates and slides relative to the second positioning component B120, the second unlocking component B250 will move accordingly relative to the second positioning component B120. Therefore, "the second unlocking component B250 is pulled outward in the second direction F2 along with the first positioning component B110 relative to the second positioning component B120" can be understood as: the second unlocking component B250 rotates together with the first positioning component B110, and eventually also faces the second direction F2 and moves closer to the door along with the first positioning component B110, making it easier for the user to operate. It should be noted that this does not mean that the second unlocking component B250 itself moves, but rather that its position changes synchronously under the influence of the first positioning component B110.

[0154] It should be noted that when the vehicle body B300 is a seat, the second release member B250 is obscured by the seat. In this case, the user can release the locking latch 171 using the first release member B240. When the vehicle body B300 is a basket, the second release member B250 is exposed. Therefore, when the basket is rotated to the second direction F2 with the first positioning component B110, the user can release the locking latch B171 by operating the second release member B250 with one hand (such as pulling), while the other hand can simultaneously remove the basket from the first positioning component B110, improving the convenience of operation.

[0155] Typically, when the first positioning component B110 is rotated relative to the second positioning component B120 to face the first direction F1, the user is usually located on the side of the positioning component B100 (such as the left or right side) when disassembling the vehicle body B300. At this time, the user can operate either the first release component B240 or the second release component B250. For example, when a user needs to control the state of the first connecting mechanism B170 using the first unlocking member B240, the user can push the first unlocking member B240 upward in the vertical direction. The driving slope B241 moves upward accordingly. Under the guidance of the driving slope B241, the relative position of the driving part B2312 on the driving slope B241 gradually changes from the top end of the driving slope B241 to the bottom end of the driving slope B241, thereby pushing the entire first locking member B231 forward to switch to the second position. At the same time, the engaging part B1711 retracts from the locking groove B2311, and the engaging hook B171 automatically switches to the unlocking position under the action of the second reset member. In this way, the engaging member B310 can disengage from the engaging hook B171. It should be noted that when the first locking member B231 is in the first position, the pushing part B2313 is located at the rear side wall B2511a of the pushing recess B2511 along the extension direction of the pushing recess B2511 (as shown in Figure 29). There is a movement gap between the pushing part B2313 and the front side wall B2511b of the pushing recess B2511. Therefore, when the driving inclined surface B241 pushes the first locking member B231 to the second position, the pushing part B2313 moves within the movement gap. Only when the movement stroke of the first locking member B231 (equivalent to the distance between the first and second positions) is greater than the length of the movement gap will the pushing part B2313 drive the second unlocking member B250 to move from the locked position to the unlocked position. When the movement stroke of the first locking member B231 is less than or equal to the length of the movement gap, the second unlocking member B250 remains relatively fixed during the process of pressing the first unlocking member B240 to disassemble the carrier body B300. Alternatively, for example, when the user needs to control the state of the first connecting mechanism B170 using the second release member B250, the user can pull the second release member B250 outward in the horizontal direction to move the second release member B250 from the locked position to the unlocked position. During the movement of the second release member B250, the pushing recess B2511 moves accordingly, and the pushing part B2313 abuts against the rear side wall B2511a of the pushing recess B2511, thereby driving the first locking member B231 to move from the first position to the second position. In this way, the engaging part B1711 can be disengaged from the locking groove B2311, and the engaging hook B171 automatically switches to the unlocked position under the action of the second reset member. It should be noted that during the process of the second unlocking member B250 driving the first locking member B231 to move, the driving part B2312 will move with the first locking member B231 to gradually move away from the driving inclined surface B241, while the first unlocking member B240 remains relatively fixed during this process.

[0156] Referring to Figures 27, 28, and 31, in one embodiment, the first positioning component B110 is provided with a release indicator mechanism B290. This release indicator mechanism B290 can directly reflect whether the locking hook B171 is in the locked or released position based on the position of the first locking member B231 within the first mounting cavity B113. Specifically, as shown in Figure 27, the release indicator mechanism B290 includes a swing member B291, a color block B292, and an observation hole B293. The swing member B291 is disposed within the first mounting cavity B113 and pivotally connected to the bottom wall of the support base B111, forming a first pivot point Q1. One end of the swing member B291 is pivotally connected to the first locking member B231. When the first locking member B231 switches between a first position and a second position, the first locking member B231 can drive the swing member B291 to swing around the first pivot point Q1. More specifically, the other end of the swing member B291 is provided with a color block B292 (e.g., green or red). An observation hole B293 is provided on the top wall of the support base B111. As mentioned above, when the first unlocking member B240 or the second unlocking member B250 is operated, the first locking member B231 will move from the first position to the second position. At this time, the end of the swing member B291 that is pivotally connected to the first locking member B231 moves with the first locking member B231, causing the entire swing member B291 to pivot. This allows the other end of the swing member B291 with the colored block B292 to move. Thus, the user can determine the position of the first locking member B231 by observing whether the colored block B292 is displayed at the observation hole B293, thereby inferring the position of the locking hook B171. Specifically, in this embodiment, when the first locking member B231 is in the first position, the colored block B292 is opposite to the observation hole B293, so the user can see the colored block B292 through the observation hole B293. When the first locking member B291 is in the second position, the color block B292 will be misaligned with the observation hole B293, and the user cannot see the color block B292 through the observation hole B293. Therefore, when the color block B292 is visible through the observation hole B293, it indicates that the locking hook B171 is in the locked position; when the color block B292 is not visible through the observation hole B293, it indicates that the locking hook B171 is in the unlocked position. Of course, in other embodiments, when the first locking member B291 is in the first position, the color block B292 is misaligned with the observation hole B293, and the user cannot see the color block B292 through the observation hole B293. However, when the first locking member B231 is in the second position, the color block B292 is opposite to the observation hole B293, and the user can see the color block B292 through the observation hole B293.Alternatively, each swing element B291 may have two different colored blocks B292 (e.g., green and red), with the two colored blocks B292 corresponding to the first locking element B231 in the first and second positions, respectively. In this way, the user can determine whether the locking hook B171 is in the locked or unlocked position by observing the color of the blocks B292 through the observation hole B293.

[0157] Referring to Figures 17 and 33, in one embodiment, a first support mechanism B128 may be provided within the second mounting cavity B123 of the second positioning component B120. On one hand, when the carrier body B300 is connected to the first positioning component B110, and the first positioning component B110 rotates relative to the second positioning component B120 toward the first direction F1, the first support mechanism B128 assists in supporting the carrier body B300 to improve the stability of the carrier body B300 mounted on the first positioning component B110. On the other hand, in this embodiment, the first support mechanism B128 is at least partially located within the groove structure B270 of both the first protrusion B124 and the second protrusion B125. The first support mechanism B128 in this embodiment can be used to strengthen the groove wall strength of the groove structure B270 used to engage the first positioning component B110. In this embodiment, there are two first support mechanisms B128, respectively located at the first protrusion B124 and the second protrusion B125.

[0158] The structure of the first support mechanism B128 located at the rear end of the second positioning component B120 is described in detail below. Referring to Figures 17, 33 to 35, the first support mechanism B128 may include a first support member B1281 and a second support member B1282. In this embodiment, as shown in Figures 34 and 35, the second positioning component B120 also includes a skeleton B129 disposed in the second mounting cavity B123. The skeleton B129 is generally U-shaped and includes a first straight rod B1291 and a second straight rod B1292 extending along the front-rear direction (i.e., the first direction F1) and spaced apart along the left-right direction (i.e., the second direction F2) of the second positioning component B120, and an arc-shaped rod B1293 whose two ends are respectively connected between the first straight rod B1291 and the second straight rod B1292. In this embodiment, the first support member B1281 located at the rear end of the second positioning component B120 is a U-shaped rod, and its two ends are respectively fixed to the first straight rod B1291 and the second straight rod B1292. There is one second support member B1282, disposed on the upper surface of the first support member B1281. Of course, in other embodiments, the number of second support members B1282 may be two or more.

[0159] Please refer to Figures 33 and 35 together. The second support member B1282 is generally a U-shaped frame structure and includes two connecting pieces B12821 arranged opposite each other, and a connecting piece B12822 connecting the two connecting pieces B12821. Each connecting piece B12821 includes a connecting body B12821a and a supporting protrusion B12821b protruding approximately in the middle of the connecting body B12821a. In this embodiment, the connecting pieces B12821 are all integrally formed, that is, the supporting protrusion B12821b and the connecting body B12821a are integrally formed. In other embodiments, the connecting piece B12821 may also be formed by connecting the connecting body B12821a and the supporting protrusion B12821b by welding, riveting, or other methods. The lower surfaces of the connecting body B12821a and the supporting protrusion B12821b form a fixing groove (not shown in the figure). The first support member B1281 is at least partially engaged in this fixing groove so that the second support member B1282 is supported on the first support member B1281. Further, to increase the connection stability between the first support member B1281 and the second support member B1282, the portion of the connecting body B12821a located below the supporting protrusion B12821b and the lower surface of the supporting protrusion B12821b are fixedly connected to the first support member B1281. The upper surface of the supporting protrusion B12821b, the connecting body B12821a, and the connecting piece B12822 form an engaging groove B12821c. Specifically, the connecting piece B12822 includes a connecting body B12822a and an abutting protrusion B12822b protruding around the lower surface of the connecting body B12822a. The connecting body B12822a has a roughly square sheet-like structure. The two abutting protrusions B12822b, which are arranged along the spacing direction of the two connecting pieces B12821, are respectively connected to the two connecting bodies B12821a. The lower surface of the supporting protrusion B12821b, the connecting body B12821a, and the abutting protrusions B12822b enclose and form a locking groove B12821c.

[0160] In this embodiment, please refer to Figures 16, 18, and 35. The first protrusion B124 and the second protrusion B125 have a communicating hole (not shown) on the side facing the mounting space B126, communicating with the second mounting cavity B123. Specifically, the communicating hole is located at the bottom of the groove in the groove structure B270. The first support member B1281 is located inside the second mounting cavity B123. The portion of the second support member B1282 located below the upper surface of the support protrusion B12821b is located inside the second mounting cavity B123. The portion of the second support member B1282 located above the upper surface of the support protrusion B12821b extends out of the second mounting cavity B123 through the communicating hole and protrudes from the upper surface of the top cover B121. The abutting protrusion B12822b of the connecting piece B12822 is located below the limiting protrusion B127. Understandably, the two second support members B1282 respectively form a portion of the first protrusion B124 and the second protrusion B125, so that the engaging groove B12821c corresponds to the position of the groove structure B270, thereby increasing the mechanical strength of the groove structure B270.

[0161] In this embodiment, the limiting protrusion B127 (or the first protrusion B124 and the second protrusion B125) is generally made of plastic, while the second support member B1282 is made of rigid material (e.g., metal sheet). Therefore, the second support member B1282 can strengthen the structural strength of the limiting protrusion B127 (or the first protrusion B124 and the second protrusion B125). When the first positioning component B110 is housed in the installation space B126, the bottom of the avoidance recess B210 of the first positioning component B110 (see Figures 21 and 22) can be inserted into the two slotted structures B270, that is, inserted into the two engaging slots B12821c located in the front-back direction (i.e., the first direction F1) of the second positioning component B120 (see Figure 18), which can further prevent the first positioning component B110 from arbitrarily disengaging from the second positioning component B120. Furthermore, the width of the second support member B1282 in the left-right direction (i.e., the distance between the two connecting pieces B12821) is slightly smaller than the width of the bottom of the U-shaped rod of the first support member B1281 in the left-right direction, and the width of the second support member B1282 in the left-right direction (i.e., the distance between the two connecting pieces B12821) is adapted to the width of the first protrusion B124 or the second protrusion B125 in the left-right direction. Thus, the larger width of the second support member B1282 increases the contact area between the bottom of the abutting protrusion B12822b and the avoidance recess B210 of the first positioning component B110, increasing the strength of the second support member B1282 during contact, and thereby improving the stability of the first positioning component B110 mounted on the second positioning component B120.

[0162] Further, as shown in Figures 22 and 33, the first support mechanism B128 may also include an auxiliary support member B1283, which is disposed inside the second support member B1282. The auxiliary support member B1283 includes interconnected support columns B12831 and a support body B12832 with a generally C-shaped structure. The support body B12832 includes a first auxiliary piece B12832a, a second auxiliary piece B12832b, and a third auxiliary piece B12832c, which are connected in sequence and arranged at an included angle. Specifically, when the auxiliary support B1283 is disposed inside the second support B1282, the auxiliary support B1283 is located between the two connecting pieces B12821. The upper surface of the first auxiliary piece B12832a is flush with the upper surface of the support protrusion B12821b, and the lower surface of the third auxiliary piece B12832c is flush with the end of the abutting protrusion B12822b away from the connecting body B12822a. The support column B12831 is used to abut between the first support B1281 and the support body B12832. In other words, the second support B1282 and the auxiliary support B1283 together form a part of the first protrusion B124 or the second protrusion B125, and the first auxiliary piece B12832a, the second auxiliary piece B12832b, and the third auxiliary piece B12832c together form the aforementioned groove structure B270. When the first positioning component B110 faces the first direction F1, the bottom of the avoidance recess B210 of the first positioning component B110 can be supported by the first auxiliary piece B12832a of the support body B12832 (refer to Figures 18 and 22), and can be abutted by the third auxiliary piece B12832c of the support body B12832. Since the support area and the abutment area are both increased, they can play a certain role in relieving pressure and reducing the pressure borne by the unit support area and the unit abutment area. This can further assist in supporting the first positioning component B110, that is, assist in supporting the carrier body B300, so as to improve the stability of the carrier body B300 installed on the first positioning component B110.

[0163] It should be noted that, along the front-rear direction, the structure of the first support mechanism B128 located at the front end of the second positioning component B120 is roughly similar to the structure of the first support mechanism B128 located at the rear end of the second positioning component B120. The only difference is that, since the second positioning component B120 has an overall structure that is lower in the front and higher in the back, the first support member B1281 of the first support mechanism B128 located at the front end of the second positioning component B120 is a straight rod rather than a U-shaped rod (see Figure 34). In addition, it should be noted that, in some embodiments, from the structure of the carrier body B300, the thickness of the part of the carrier body B300 used to support the child's buttocks is less than the thickness of the part used to support the child's legs, and the lower surface of the bottom of the carrier body B300 is inclined; in other words, the bottom of the carrier body B300 is thicker in the front and thinner in the back, and the lower surface of the bottom is inclined. To ensure that a child riding in the vehicle body B300 can sit in a roughly horizontal position when it is installed on the positioning component B100 and facing the front of the vehicle, the upper surface of the second positioning component B120 is designed with a lower front and higher rear. This allows it to roughly align with the lower surface of the vehicle body B300, making the vehicle body B300 more stable when mounted on the positioning component B100. Furthermore, the inclined surface fit facilitates the rotation and sliding of the vehicle body B300 relative to the second positioning component B120 as the first positioning component B110 moves. Alternatively, in other embodiments, the bottom of the vehicle body B300 can have a planar fit with the second positioning component B120, allowing both first support members B1281 in the second mounting cavity B123 to be either straight or curved rods (such as U-shaped rods).

[0164] In one embodiment, the positioning component B100 further includes an anti-misuse mechanism B220 (see FIG. 46). This mechanism is movably disposed on the first positioning component B110 or the second positioning component B120 to selectively allow or restrict the movement of the first slider B141 or the second slider B142, thereby selectively restricting the rotation angle of the first positioning component B110 relative to the second positioning component B120. Specifically, in this embodiment, the anti-misuse mechanism B220 includes a blocking member (not shown in the figure), which is movably disposed on the movement path of the second slider B142 within the second track segment B1312 to restrict the first positioning component B110 from rotating relative to the second positioning component B120 towards the front of the vehicle.

[0165] In one embodiment, the anti-misuse mechanism B220 further includes a release assembly disposed on the second positioning assembly B120 and connected to the blocking member, for driving the blocking member out of the second track segment B1312, thereby allowing the second sliding member B142 to move in the second track segment B1312. Specifically, as shown in Figures 36 and 37, the release assembly includes an operating member B221 and a traction member (not shown in the figures). The operating member B221 is movably disposed on the second positioning assembly B120 and has an unlocked position and a locked position. More specifically, the top cover B121 is provided with a through hole B1211 (see Figures 16 and 36). The operating member B221 is movably disposed in the second mounting cavity B123. The operating part of the operating member B221 extends out of the second mounting cavity B123 through the through hole B1211 and protrudes from the surface of the top cover B121, thus facilitating user operation. The traction member connects the operating member B221 and the blocking member. When the operating member B221 switches from the locked position to the unlocked position, the operating member B221 drives the blocking member to exit the second track section B1312 via the traction member. In this embodiment, a support plate B222 is provided in the second mounting cavity B123, and the operating member B221 is movably mounted on the support plate B222. Specifically, the support plate B222 and the operating member B221 can be straight plate structures. Of course, in other embodiments, the support plate B222 and the operating member B221 can be arc-shaped structures, which can improve the smoothness of the operation member B221 moving in the left and right directions on the support plate B222.

[0166] In one embodiment, as shown in FIG28, the positioning component B100 further includes a first limiting mechanism B260. The first limiting mechanism B260 is disposed between the first positioning component B110 and the second positioning component B120. When the vehicle body B300 is a seat, the first limiting mechanism B260 is used to selectively allow or restrict the seat from disengaging from the first positioning component B110, which can be regarded as the first limiting mechanism B260 selectively allowing or restricting the first connecting mechanism B170 to switch between a locked state and an unlocked state. Specifically, when the seat rotates with the first positioning component B110 to face the front of the vehicle along the first direction F1, the first limiting mechanism B260 is used to restrict the seat from disengaging from the first positioning component B110. When the first positioning component B110 rotates relative to the second positioning component B120 to face the rear of the vehicle along the first direction F1 and to face the second direction F2, the first limiting mechanism B260 can allow the seat to disengage from the first positioning component B110. More specifically, as shown in Figure 28, when the first positioning component B110 is facing the front of the car, the first limiting mechanism B260 enters the movement path of the locking and retaining mechanism B230 (i.e., the first locking member B231), restricting the movement of the locking and retaining mechanism B230, thereby keeping the locking hook B171 in the locked position.

[0167] Specifically, referring to Figures 16 and 21, the first limiting mechanism B260 includes a first limiting groove B261 and a first limiting member B262. The first limiting groove B261 is disposed on the top cover B121, and the bottom of the support base B111 is provided with a first limiting hole B1112, which communicates with the first mounting cavity B113. The first limiting member B262 is movably disposed within the first mounting cavity B113, and at least part of the first limiting member B262 can extend out of the first mounting cavity B113 through the first limiting hole B1112. When the first limiting member B262 extends out of the first mounting cavity B113 through the first limiting hole B1112 and is inserted into the first limiting groove B261, the first limiting member B262 retracts from the movement path of the first locking member B231, allowing the engaging hook B171 to be in the unlocked position, thereby allowing the seat to be disengaged from the first positioning assembly B110. When the first limiting member B262 retracts from the first limiting groove B261, it is positioned within the movement path of the first locking member B231, thus restricting the engagement hook B171 from switching to the release position, and preventing the seat from detaching from the first positioning assembly B110. Specifically, when the first positioning assembly B110 rotates relative to the second positioning assembly B120 to face the front of the vehicle, the first limiting member B262 retracts from the first limiting groove B261. This prevents the seat from being removed from the first positioning assembly B110 when facing the front of the vehicle.

[0168] Referring to Figures 16 and 21, in one embodiment, the first limiting hole B1112 is located between the first sliding member B141 and the second sliding member B142, thus placing the first limiting member B262 between the first sliding member B141 and the second sliding member B142. When the first positioning component B110 rotates relative to the second positioning component B120 along the first direction F1 from the direction towards the rear of the vehicle to the direction towards the second direction F2, the sliding path of the first limiting member B262 coincides with the first limiting groove B261. Specifically, the first limiting hole B1112 is located at the midpoint between the first sliding member B141 and the second sliding member B142, and the first limiting groove B261 is, for example, a semi-circular groove, the radius of which is the distance between the first limiting member B262 and the first sliding member B141. It should be noted that in this embodiment, the first sliding member B141 is located at the center of the first positioning component B110. Specifically, the opening of the semi-circular groove faces the rear of the vehicle along the first direction F1. When the first positioning component B110 rotates relative to the second positioning component B120 toward the rear of the vehicle, the first limiting member B262 is located at the midpoint of the first limiting groove B261. Specifically, the two ends of the first limiting groove B261 are connected to the third track segment B1321 and the fourth track segment B1322, respectively. The first track segment B1311, the third track segment B1321, and the fourth track segment B1322 are all divided into a first segment B1341 and a second segment B1342 by the first limiting groove B261. The first segment B1341 is closer to the intersection center B133 than the second segment B1342.

[0169] It should be noted that, in this embodiment, although the second track segment B1312 is not divided into the first segment B1341 and the second segment B1342 by the first limiting groove B261, it can be understood that the part of the second track segment B1312 away from the intersection center B133 can also be regarded as the second segment B1342, and the part of the second track segment B1312 close to the intersection center B133 can also be regarded as the first segment B1341.

[0170] In one embodiment, the first slider B141 may include a first sliding rod B1411 and a first slider B1412 connected together (see Figures 48 and 49), and the second slider B142 may include a second sliding rod B1421 and a second slider B1422 connected together (see Figures 21 and 22). The first slider B1412 is connected to the first positioning component B110 via the first sliding rod B1411, and the second slider B1422 is connected to the first positioning component B110 via the second sliding rod B1421. In one embodiment, the first track B131 may include a first channel and a first groove, and the second track B132 may include a second channel B1323 and a second groove B1324 (see Figures 46 and 47). Both the first channel and the second channel B1323 are located on the lower surface of the top cover B121, facing the second mounting cavity B123. They intersect and communicate with each other, and both the first channel and the second channel B1323 are connected to the second mounting cavity B123. The first groove is located inside the first channel, and the second groove B1324 is located inside the second channel B1323. Both the first groove and the second groove B1324 are through-grooves penetrating the upper and lower surfaces of the top cover B121. Specifically, when the first sliding member B141 slides along the second track B132, it can be considered that the first sliding rod B1411 slides within the second groove B1324, while the first slider B1412 slides within the second channel B1323. When the second slider B142 slides along the first track B131, it can be considered that the second sliding rod B1421 slides in the first groove, while the second slider B1422 slides in the first channel.

[0171] It should be noted that the first slider B141 and the second slider B142 can both be integrally formed structures, that is, the first slider B1412 and the first sliding rod B1411 are integrally formed, and the second slider B1422 and the second sliding rod B1421 are integrally formed, and the two are integral structures. Of course, in other embodiments, the first slider B1412 and the first sliding rod B1411 are different components. The first slider B141 can be formed by connecting the first slider B1412 and the first sliding rod B1411 by welding, riveting or other methods; the second slider B1422 and the second sliding rod B1421 are also different components. The second slider B1422 can be formed by connecting the second slider B1422 and the second sliding rod B1421 by welding, riveting or other methods.

[0172] In one embodiment, when the first positioning component B110 rotates relative to the second positioning component B120 to face the left side along the second direction F2, the first positioning component B110 is pulled outward relative to the second positioning component B120 in the left direction (see Figure 41); when the first positioning component B110 rotates relative to the second positioning component B120 to face the right side along the second direction F2, the first positioning component B110 is pulled outward relative to the second positioning component B120 in the right direction (refer to Figures 15 and 16). Referring to Figures 14 to 16, when the first positioning component B110 rotates relative to the second positioning component B120 to the second direction F2 to be pulled out, a portion of the first track B131 and a portion of the second track B132 on the second positioning component B120 are exposed. For example, as shown in Figure 15, when the first positioning component B110 is oriented towards the right side of the car along the second direction F2, the second section B1342 of the first track segment B1311, the second section B1342 of the second track segment B1312, the second section B1342 of the third track segment B1321, and a portion of the first section B1341 of the third track segment B1321 are exposed. Referring to Figures 16 and 41, when the first positioning component B110 is oriented towards the left side of the vehicle along the second direction F2, the second section B1342 of the first track segment B1311, the second section B1342 of the second track segment B1312, the second section B1342 of the fourth track segment B1322, and a portion of the first section B1341 of the fourth track segment B1322 are exposed. To prevent foreign objects from falling into the exposed first track B131 and second track B132 and affecting the normal use of the positioning component B100, and to prevent the user's hand or other parts from accidentally entering the exposed first track B131 and second track B132 during the rotation of the first positioning component B110 and causing injury, the positioning component B100 provided in the first embodiment of the third aspect of this application also includes a shielding mechanism B150 (see Figure 16). The blocking mechanism B150 is disposed on the second positioning component B120 and located on the tracks (first track B131 and second track B132), and the blocking mechanism B150 is capable of selectively blocking at least a portion of the tracks.

[0173] Referring to Figures 16, 38, and 39, in one embodiment, the blocking mechanism B150 includes a blocking member B151. Specifically, the blocking member B151 includes a main blocking member B151a, which is disposed on the side of the second positioning component B120 facing the first positioning component B110. In one embodiment, the blocking mechanism B150 includes at least one of the above-described main blocking member B151a, and at least one of the first track segment B1311, the second track segment B1312, the third track segment B1321, or the fourth track segment B1322 is provided with a main blocking member B151a. Specifically, in this embodiment, there are four main blocking components B151a. The first track segment B1311 and the second track segment B1312 of the first track B131 are each provided with a main blocking component B151a, and the third track segment B1321 and the fourth track segment B1322 of the second track B132 are also each provided with a main blocking component B151a.

[0174] The following description uses the main shielding component B151a located at the fourth track section B1322 as an example to illustrate the structure and location of the main shielding component B151a.

[0175] Referring to Figure 38, in one embodiment, the second positioning component B110 has a limiting recess B1212 on the side facing the first positioning component B110. This is equivalent to the top cover B121 having a limiting recess B1212 on the side away from the second mounting cavity B123. The limiting recess B1212 is recessed relative to the upper surface of the top cover B121 and surrounds the fourth track segment B1322. In this embodiment, the limiting recess B1212 surrounds a portion of the track segment area of ​​the fourth track segment B1322; specifically, the limiting recess B1212 surrounds the second section B1342 of the fourth track segment B1322. Therefore, when a main blocking member B151a is provided in the limiting recess B1212, the main blocking member B151a can block a portion of the track section area extending along the length direction of the fourth track section B1322, that is, the main blocking member B151a can block the second section B1342 of the fourth track section B1322.

[0176] Specifically, referring to Figure 39, the main blocking component B151a may include a first blocking piece B1511 and a second blocking piece B1512. The first blocking piece B1511 and the second blocking piece B1512 are respectively disposed on opposite sides of the track and extend in opposite directions. A sliding gap B1514 is left between the first blocking piece B1511 and the second blocking piece B1512. The sliding gap B1514 is connected to the fourth track segment B1322, and the orthographic projection of the sliding gap B1514 on the second positioning component B120 is located within the range of the fourth track segment B1322.

[0177] To prevent the main blocking member B151a from interfering with the rotation and sliding operations between the first positioning component B110 and the second positioning component B120 after it is installed on the upper surface of the top cover B121, in this embodiment, the thickness of the main blocking member B151a (the first blocking piece B1511 and the second blocking piece B1512) is less than or equal to the depth of the limiting recess B1212.

[0178] Referring to Figures 16, 38, and 39, in one embodiment, both the first blocking plate B1511 and the second blocking plate B1512 include a connecting portion B15111 and a blocking portion B15112. The connecting portion B15111 is connected within the limiting recess B1212, while the blocking portion B15112 extends obliquely towards the interior of the fourth track segment B1322 relative to the connecting portion B15111. In other words, the blocking portion B15112 tends to extend into the second groove B1324 of the fourth track segment B1322, and can be considered to have a tendency to extend obliquely downwards. This ensures that the second sliding member B142 can smoothly slide from the intersection center B133 along the fourth track segment B1322 towards the end away from the intersection center B133, avoiding interference between the first blocking plate B1511 and the second blocking plate B1512 and the second sliding member B142.

[0179] In one embodiment, the connecting portion B15111 can be connected to the limiting recess B1212 by means of adhesive bonding, snap-fitting, or riveting. Specifically, in this embodiment, the connecting portion B15111 is connected to the limiting recess B1212 by means of adhesive bonding.

[0180] In one embodiment, the main shielding member B151a is an elastic soft structure, thus allowing the main shielding member B151a to have an initial state and a deformed state. Specifically, the diameter D1 of the first sliding rod B1411 is greater than the width M1 of the sliding gap B1514 (see Figures 39 and 49). When the first sliding rod B1411 is located within the sliding gap B1514 of the main shielding member B151a on the third track segment B1321 or the fourth track segment B1322, under the compression of the first sliding rod B1411, the main shielding member B151a located on the third track segment B1321 or the fourth track segment B1322 undergoes elastic deformation to be in a deformed state. At this time, the shielding portion B15112 of the first shielding piece B1511 and the shielding portion B15112 of the second shielding piece B1512 move away from each other under the compression of the first sliding rod B1411. When the first sliding rod B1411 moves out of the sliding gap B1514 of the main blocking member B151a located on the third track section B1321 or the fourth track section B1322, the main blocking member B151a resets to its initial state. At this time, the blocking portion B15112 of the first blocking piece B1511 and the blocking portion B15112 of the second blocking piece B1512 approach each other, and the first blocking piece B1511 and the second blocking piece B1512 cooperate to cover the third track section B1321 or the fourth track section B1322. It should be noted that in this embodiment, the diameter D2 of the second sliding rod B1421 is also larger than the width M1 of the sliding gap B1514 (see Figures 22 and 39). Therefore, when the second sliding rod B1421 is located within the sliding gap B1514 of the main blocking member B151a on the first track segment B1311 or the second track segment B1312, the main blocking member B151a on the first track segment B1311 or the second track segment B1312 undergoes elastic deformation and is in a deformed state under the compression of the second sliding rod B1421. In summary, it can be understood that when the sliding member moves into the sliding gap B1514, the main blocking member B151a will be compressed and in a deformed state. When the sliding member moves out of the sliding gap B1514, the main blocking member B151a returns to its initial state to block the corresponding track.

[0181] In one embodiment, the main shielding member B151a can be made of materials such as rubber, silicone, TPV, TPR, TPO, TPU, TPEE, or TEP. In this way, the main shielding member B151a on the fourth track segment B1322 will not obstruct the sliding of the first sliding member B141 along the fourth track segment B1322. Simultaneously, when the first sliding member B141 does not enter the fourth track segment B1322, the main shielding member B151a can automatically return to its initial state to shield the fourth track segment B1322, thereby effectively reducing the risk of foreign objects falling into the fourth track segment B1322, and also effectively reducing the probability of the user's hand accidentally entering the fourth track segment B1322. It should be noted that the main shielding member B151a is not limited to being made of one of the eight materials mentioned above. Furthermore, the statement that "the main blocking member B151a can automatically reset to its initial state to block the fourth track segment B1322" does not mean that the main blocking member B151a achieves absolute and complete coverage along the width direction of the fourth track segment B1322 to block it. Rather, it means that except for the area occupied by the fourth track segment B1322 corresponding to the sliding gap B1514, the remaining portion is effectively blocked. In this embodiment, the width M1 of the sliding gap B1514 is small, even close to 0. This ensures that the main blocking member B151a effectively blocks the fourth track segment B1322 in its initial state.

[0182] Referring to Figures 16 and 39, in one embodiment, the main shielding member B151a may further include a first transition piece B1513. The first transition piece B1513 is disposed at the end of the fourth track segment B1322 away from the intersection center B133 and connects the first shielding piece B1511 and the second shielding piece B1512. Specifically, the first transition piece B1513 connects the connecting portion B15111 of the first shielding piece B1511 and the connecting portion B15111 of the second shielding piece B1512. It should be noted that the first shielding piece B1511, the first transition piece B1513, and the second shielding piece B1512 can be integrally formed; of course, in other embodiments, the first transition piece B1513 can also be connected between the first shielding piece B1511 and the second shielding piece B1512 by means of bonding or other methods. By connecting the first shielding piece B1511 and the second shielding piece B1512 with the first transition piece B1513, the convenience of setting the main shielding member B151a at each track section can be improved.

[0183] It should be noted that, in this embodiment, the main blocking member B151a located in the second segment B1342 may include a first transition piece B1513, that is, the main blocking member B151a includes a first blocking piece B1511, a first transition piece B1513, and a second blocking piece B1512 connected in sequence. Of course, the first transition piece B1513 may also be omitted from the main blocking member B151a located in the second segment B1342, that is, the main blocking member B151a may only include the relatively independent first blocking piece B1511 and second blocking piece B1512.

[0184] Of course, in other embodiments, the structure of the main shielding member B151a can also be considered as having a sliding gap B1514, with at least one end of the sliding gap B1514 penetrating through the main shielding member B151a, so that the main shielding member B151a forms a first shielding piece B1511 and a second shielding piece B1512. For example, one end of the sliding gap B1514 penetrates through the main shielding member B151a to divide the main shielding member B151a to form a connected first shielding piece B1511 and a second shielding piece B1512 (not shown in the figure). Alternatively, both ends of the sliding gap B1514 penetrate the main shielding member B151a, dividing the main shielding member B151a to form independent first shielding pieces B1511 and second shielding pieces B1512 (see Figures 39 and 47, but in Figure 39, the two independent first shielding pieces B1511 and second shielding pieces B1512 are connected by a first transition piece B1513). Specifically, in this embodiment, both ends of the main shielding member B151a are penetrated by the sliding gap B1514.

[0185] Referring to Figures 16 and 38, specifically, in this embodiment, the end of the second track segment B1312 away from the intersection center B133, the second section B1342 of the first track segment B1311, the second section B1342 of the third track segment B1321, and the second section B1342 of the fourth track segment B1321 are all provided with the aforementioned main shielding member 151a.

[0186] Referring to Figures 16 and 38, in one embodiment, the second positioning component B120 facing the first positioning component B110 is further provided with a protruding structure B280, which is arranged around the edge of each track. Specifically, the protruding structure B280 protrudes relative to the upper surface of the top cover B121, and is made of a hard, wear-resistant material, such as metal. Thus, when the first positioning component B110 rotates and slides relative to the second positioning component B120 along the track, the protruding structure B280 provides sliding support for the first positioning component B110, preventing the upper surface of the second positioning component B120 (i.e., the upper surface of the top cover B121) from being scratched by the first positioning component B110 during movement. It should be noted that in this embodiment, the height of the protruding structure B280 is greater than the thickness of the main blocking member B151a, and the edge of the first limiting groove B261 is also provided with a protruding structure B280.

[0187] Figure 40 shows a perspective view of a positioning component B100 according to a second embodiment of the third aspect of this application. The positioning component B100 may include a first positioning component B110, a second positioning component B120, and a blocking mechanism B150. The positioning component B100 in this embodiment is a variation of the positioning component B100 in the first embodiment described above. Therefore, unless otherwise specified, the structure of each component of the positioning component B100 in this embodiment, the connection relationships between the components, and the positional relationships can be found in the description of the first embodiment of the third aspect above. The following mainly describes the differences between this embodiment and the first embodiment of the third aspect described above.

[0188] In this embodiment, in addition to the main blocking member B151a described above, the blocking member B151 also includes an auxiliary blocking member B151b, which is also located on the side of the second positioning component B120 facing the first positioning component B110. At least one main blocking member B151a and one auxiliary blocking member B151b are provided. At least one of the following is provided: the end of the second track segment B1312 away from the intersection center B133; the second section B1342 of the first track segment B1311; the second section B1342 of the third track segment B1321; and the second section B1342 of the fourth track segment B1322. The main blocking member B151a is provided in at least one of the first section B1341 of the third track segment B1321 and the first section B1341 of the fourth track segment B1322. The auxiliary blocking member B151b is provided in at least one of these.

[0189] Specifically, in this embodiment, as shown in Figure 40, the end of the second track segment B1312 away from the intersection center B133, the second section B1342 of the first track segment B1311, the second section B1342 of the third track segment B1321, and the second section B1342 of the fourth track segment B1322 are respectively provided with main blocking members B151a, and the first section B1341 of the third track segment B1321 and the first section B1341 of the fourth track segment B1322 are respectively provided with auxiliary blocking members B151b. It should be noted that the structure of the auxiliary blocking member B151b is roughly the same as that of the main blocking member B151a. In addition, the material of the auxiliary blocking member B151b is also the same as that of the main blocking member B151a. Therefore, the auxiliary blocking member B151b also has an initial state and a deformed state, and when the auxiliary blocking member B151b is in the initial state, it can block the corresponding first section B1341. Of course, in some embodiments, the structure and material of the main blocking member B151a and the auxiliary blocking member B151b may also be different. It should be reiterated that "the structure of the auxiliary blocking member B151b is substantially the same as the structure of the main blocking member B151a" means that when the main blocking member B151a does not include the first transition piece B1513, the structure of the auxiliary blocking member B151b is the same as that of the main blocking member B151a. In other words, in this embodiment, the auxiliary blocking member B151b does not include the first transition piece B1513, allowing the first segment B1341 to communicate with the second segment B1342 and the intersection center B133 respectively, without interfering with the sliding of the first sliding member B141. Understandably, when the first positioning component B110 rotates relative to the second positioning component B120 to the right or left along the second direction F2, the auxiliary shielding component B151b can shield the exposed first section B1341 of the third track segment B1321 or the first section B1341 of the fourth track segment B1322 (refer to Figures 15 and 40). This further improves the reliability of the rotation and sliding of the first positioning component B110 relative to the second positioning component B120, and enhances the safety and reliability of the positioning component B100 in use.

[0190] Figures 41 and 42 show perspective views of a positioning component B100 according to a third embodiment of the third aspect of this application. The positioning component B100 may include a first positioning component B110, a second positioning component B120, and a blocking mechanism B150'. The positioning component B100 in this embodiment is a variation of the positioning component B100 of the first embodiment of the third aspect described above. Therefore, unless otherwise specified, the structure of each component of the positioning component B100 in this embodiment, the connection relationships between the components, and the positional relationships can be found in the description of the first embodiment of the third aspect above. The following mainly describes the differences between this embodiment and the first embodiment of the third aspect described above.

[0191] Referring to Figures 42, 44, and 45, the structure and location of the blocking mechanism B150' are modified in this embodiment. The blocking mechanism B150' includes a blocking member B151' and a mounting assembly B152. The blocking member B151' is located on the side of the second positioning assembly B120 facing away from the first positioning assembly B110. Specifically, the blocking member B151' is fixed to the side of the top cover B121 facing the second mounting cavity B123 by the mounting assembly B152.

[0192] In one embodiment, at least one blocking member B151' is provided, and the blocking member B151' is provided in at least one of the first track segment B1311, the second track segment B1312, the third track segment B1321, or the fourth track segment B1322. Specifically, in this embodiment, the blocking member B151' is provided in each of the above-mentioned track segments. The structure and setting position of the blocking member B151' are described in detail below, taking the blocking member B151' located on the fourth track segment B1322 as an example.

[0193] Referring to Figures 43 to 47, the shielding member B151' has a structure largely the same as the main shielding member B151a in the first embodiment of the third aspect described above. It may include a first shielding piece B1511' and a second shielding piece B1512'; or it may include a first shielding piece B1511', a first transition piece, and a second shielding piece B1512'. The lengths of the first shielding piece B1511' and the second shielding piece B1512' can be approximately the same as the length of the fourth track segment B1322, thus protecting the entire fourth track segment B1322. Of course, in other embodiments, the lengths of the first shielding piece B1511' and the second shielding piece B1512' can be less than the length of the fourth track segment B1322.

[0194] Referring to Figures 44 and 47, in this embodiment, the blocking member B151' includes only a first blocking piece B1511' and a second blocking piece B1512'. Both the first blocking piece B1511' and the second blocking piece B1512' are located within the second channel B1323 of the fourth track section B1322, and the first blocking piece B1511' and the second blocking piece B1512' are respectively located on both sides of the second groove B1324 along the first direction F1. As shown in Figures 45 and 49, both the first shielding plate B1511 and the second shielding plate B1512 include a connecting portion B15111' and a shielding portion B15112'. The shielding portion B15112' of the first shielding plate B1511' and the shielding portion B15112' of the second shielding plate B1512' extend obliquely towards the interior of the fourth track section B1322 relative to their corresponding connecting portion B15111'. In other words, the shielding portion B15112' has a tendency to extend into the interior of the second groove B1324 of the fourth track section B1322 (in a direction away from the second mounting cavity B123), that is, the shielding portion B15112' can be regarded as having a tendency to extend obliquely upward (see Figure 45). This ensures that the second slider B142 can smoothly slide from the intersection center B133 along the fourth track segment B1322 to the end away from the intersection center B133, avoiding interference between the first blocking plate B1511' and the second blocking plate B1512' and the second slider B142.

[0195] In one embodiment, the shielding member B151' is fixed to the top cover B121 by means of snap-fit, adhesive, or riveting. In this embodiment, as shown in Figures 45 and 47, the shielding member B151' is fixed to the top cover B121 by a mounting assembly B152. The mounting assembly B152 includes pressing members B1521, the number of which is the same as and corresponds to the number of shielding members B151'. The pressing members B1521 are located on the side of the top cover B121 facing the second mounting cavity B123, and the shielding member B151' is fixed to the top cover B121 by its corresponding pressing member B1521.

[0196] In this embodiment, the structure of the pressing member B1521 is described using the shielding member B151' and the pressing member B1521 located at the fourth track section B1322 as examples. Specifically, the pressing member B1521 is located within the second channel B1323 of the fourth track section B1322 and is arranged around the second slide groove B1324 of the fourth track section B1322. The pressing member B1521 can press and fix the connecting portion B15111' of the first shielding piece B1511' and the connecting portion B15111' of the second shielding piece B1512' to both sides of the second slide groove B1324 along the first direction F1. More specifically, the pressing member B1521 may include a first pressing piece B15211, a second transition piece B15212, and a second pressing piece B15213 connected in sequence, with the second transition piece B15212 forming an angle with both the first pressing piece B15211 and the second pressing piece B15213. The first pressing piece B15211 is used to press and fix the connecting portion B15111' of the first blocking piece B1511' against one side of the second slide groove B1324 along the first direction F1, and the second pressing piece B15213 is used to press and fix the connecting portion B15111' of the second blocking piece B1512' against the other side of the second slide groove B1324 along the first direction F1. Of course, in other embodiments, the second transition piece B15212 may be omitted. It should be noted that the material of the pressing member B1521 may include, but is not limited to, a hard material, such as a metal.

[0197] Referring to Figures 44, 45, and 47, in one embodiment, the mounting assembly B152 further includes a fastener B1522 (such as a screw or bolt), and at least one fastener B1522 is provided. Specifically, the top cover B121 has at least one first connecting hole B1212, and the pressing member B1521 has at least one second connecting hole B15214. Specifically, at least three second connecting holes B15214 may be provided, wherein the second transition piece B15212 has at least one second connecting hole B15214, the first pressing piece B15211 may also have at least one second connecting hole B15214, and the second pressing piece B15213 may also have at least one second connecting hole B15214, without specific limitations. In this way, the stability of the shielding member B151 fixed to the second positioning assembly B120 can be improved. Fastener B1522 is used to pass through the first connecting hole B1212 and the second connecting hole B15214 to connect the pressing member B1521 to the top cover B121. By means of the cooperation of fastener B1522 and pressing member B1521, each blocking member B151 can be stably fixed under the corresponding rail segment.

[0198] Similarly, when the first sliding rod B1411 is located within the sliding gap B1514' of the blocking member B151' on the third track section B1321 or the fourth track section B1322, under the compression of the first sliding rod B1411, the blocking member B151' located on the third track section B1321 or the fourth track section B1322 undergoes elastic deformation to be in a deformed state. At this time, the blocking portion B15112' of the first blocking piece B1511' and the blocking portion B15112' of the second blocking piece B1512' move away from each other under the compression of the first sliding rod B1411, and the blocking member B151' will not interfere with the movement of the first sliding rod B1411. When the first sliding rod B1411 moves out of the sliding gap B1514' of the blocking member B151' located on the third track section B1321 or the fourth track section B1322, the blocking member B151' resets to its initial state. At this time, the blocking portions B15112' of the first blocking plate B1511' and the second blocking plate B1512' approach each other, and the first blocking plate B1511' and the second blocking plate B1512' cooperate to cover the third track section B1321 or the fourth track section B1322, preventing foreign objects from falling into the second mounting cavity B123 from the slot of the second slide groove B1323 and affecting the normal use of the positioning assembly B100. In summary, it can be understood that when the sliding member moves into the sliding gap B1514', the blocking member B151' will be squeezed into a deformed state. When the slider moves out of the sliding gap B1514', the blocking component B151' returns to its initial state to block the corresponding track.

[0199] As described above, in the first embodiment and the second embodiment of the third aspect, each shielding member B151 (i.e., the main shielding member B151a and / or the auxiliary shielding member B151b) can be considered to be located above the first slide rail and the second slide rail B1324, and in the third embodiment of the third aspect, each shielding member B151' can be considered to be located below the first slide rail and the second slide rail B1324. When each shielding member B151 in the first embodiment and the second embodiment of the third aspect is in its initial state, each shielding member B151 in the first embodiment and the second embodiment of the third aspect can shield and protect the first track B131 and the second track B132. Similarly, when each shielding member B151' in the third embodiment of the third aspect is in its initial state, each shielding member B151' in the third embodiment of the third aspect can also shield and protect the first track B131 and the second track B132.
