Description

[Technical Field]

[0001] This application relates to the field of infant and toddler products technology, and in particular to an angle adjustment mechanism and a carrier containing the same. [Previous Technology]

[0002] Child safety seats are seats specifically designed for children and installed inside cars. Currently, child safety seats generally include a base, and some can be locked into an infant carrier. These child safety seats with a locked infant carrier are generally rear-facing. To ensure the child's comfort, an angle adjustment mechanism is installed at the bottom of the base. However, existing angle adjustment mechanisms generally require adjustment before installation onto the car seat, or adjustment before locking into the infant carrier, rather than allowing for easy adjustment of the infant carrier's reclining angle, causing inconvenience to the user.

[0032] Figures 3, 4, and 11 schematically illustrate a perspective view of a vehicle 1000 provided according to an embodiment of this application and an angle adjustment mechanism 200 provided according to an embodiment of this application. The vehicle 1000 includes a positioning component 100, an angle adjustment mechanism 200 provided according to an embodiment of this application, and a vehicle body 300. The positioning component 100, the angle adjustment mechanism 200, and the vehicle body 300 will be described below concurrently with the description of the vehicle 1000. The vehicle body 300 can be an infant carrier, a booster seat, or a child safety seat. The positioning component 100 can be fixed to a car seat, for example, by configuring ISOFIX connectors. The vehicle body 300 can be fixed to the car seat by a structure such as a pull strap, or by a car seat belt installed in the car.

[0033] Figures 1 to 4 schematically show perspective views of a vehicle 1000 provided according to an embodiment of the present application. The vehicle body 300 can be connected to the positioning assembly 100. Figures 4 to 5 and 16 schematically show the positioning assembly provided according to an embodiment of the present application. The positioning assembly 100 includes a first positioning assembly 110 and a second positioning assembly 120, the first positioning assembly 110 being rotatable and slidable relative to the second positioning assembly 120. The first positioning assembly 110 includes a connecting seat 113 and a rotating seat 114 pivotally connected to the connecting seat 113. An angle adjustment mechanism 200 is disposed on the positioning assembly 100 and connected to the connecting seat 113 for adjusting the tilt angle α of the connecting seat 113 relative to the rotating seat 114. By adjusting the tilt angle α of the connecting seat 113 relative to the rotating seat 114, the angle of the vehicle body 300 connected to the positioning assembly 100 relative to the positioning assembly 100 can be adjusted, thereby improving the comfort of the user riding on the vehicle body 300.

[0034] Referring to Figures 2, 5, and 6, the positioning component 100 can be secured to a vehicle seat, for example, by configuring an ISOFIX connector. The positioning component 100 includes a first positioning component 110 and a second positioning component 120. The first positioning component 110 can be connected to a vehicle body 300. As shown in Figure 1, the vehicle body 300 is mounted on a connector 113 of the first positioning component 110. The second positioning component 120 can be connected to the vehicle seat. In one embodiment, the second positioning component 120 is provided with an ISOFIX connector 124A and a support leg 124B. The ISOFIX connector 124A is generally located at the rear end of the second positioning component 120, and the support leg 124B is generally located at the front end of the second positioning component 120. Specifically, when the second positioning component 120 is disposed on the vehicle seat, the ISOFIX connector 124A is used to securely connect the second positioning component 120 to the vehicle seat, and the support leg 124B is used to abut against the floor of the vehicle interior. With the connection and support of ISOFIX connector 124A and support leg 124B, the second positioning component 120 can be stably installed inside the vehicle. For example, the vehicle 1000 shown in Figures 2 to 4 is in a "rear-facing use mode". The "rear-facing use mode" refers to a mode in which, when the positioning component 100 is installed in the vehicle seat, with the vehicle as a reference, the user's face is facing the rear of the vehicle when sitting on the vehicle body 300, and the front end of the first positioning component 110 faces the rear of the vehicle, while the rear end of the first positioning component 110 faces the front of the vehicle. The vehicle 1000 or the positioning component 100 can also be adjusted to a "side-facing use mode" (as shown in Figure 16). The "side-facing use mode" refers to a mode in which, when the positioning component 100 is installed in the vehicle seat, with the vehicle as a reference, the user's face is facing the vehicle door, including the left or right door, and the front end of the first positioning component 110 faces the left or right door. Furthermore, although not shown in the figures, the vehicle 1000 can also be used in a "forward-facing usage mode." A "forward-facing usage mode" refers to a mode in which, when the positioning component 100 is installed in a car seat, with the car as a reference, the user's face faces the front of the car when seated on the vehicle body 300. In this case, the rear end of the first positioning component 110 faces the rear of the car, and the front end of the first positioning component 110 faces the front of the car. The following description uses the vehicle 1000 in a "rear-facing usage mode" as an example. Those skilled in the art will understand that the vehicle 1000 and the positioning component 100 of this application can be used in either a "sideways usage mode" or a "forward-facing usage mode."

[0035] Referring to Figures 14 to 16, the first positioning component 110 can rotate and slide relative to the second positioning component 120. One of the first positioning component 110 and the second positioning component 120 (the second positioning component 120 shown in Figure 14) is provided with a track 120A, and the other (the first positioning component 110 shown in Figure 15) is provided with a slider 110A. The slider 110A can rotate and slide along the track 120A, so that the first positioning component 110 has a rearward use mode and a lateral use mode on the second positioning component 120.

[0036] Referring to Figures 14 and 16, the second positioning component 120 may include a base 123. The base 123 may have a relatively flat upper surface 123A. A track 120A may be provided on the base 123. The track 120A may include a first track 121 and a second track 122 that intersect. When the second positioning component 120 is installed in a car seat, the end of the base 123 facing the front of the car is the front end of the base 123, the other end of the base 123 facing the rear of the car is the rear end of the base 123, the side of the base 123 facing the left side door of the car is the left side of the base 123, and the other side of the base 123 facing the right side door of the car is the right side of the base 123. As shown in Figure 14, the first track 121 may be located in the upper surface 123A between the front end and the rear end of the base 123 and extends from the left side of the base 123 to the right side. As shown in Figure 14, the first track 121 may be located approximately in the middle between the front end and the rear end of the base 123. The second track 122 is a T-shaped groove formed in the upper surface 123A of the base and intersecting the first track 121. As shown in FIG. 14, the second track 122 extends from a midpoint between the left and right sides of the first track 121 to the front end of the base 123. The second track 122 may also be offset to the left or right of the base 123 relative to the midpoint between the left and right sides of the first track 121, and / or extend from a position near the front end of the base 123 to a position near the rear end of the base 123 (e.g., the first track 121 and the second track 122 intersect in a cross shape). The first track 121 and the second track 122 may also be configured as grooves intersecting at other angles. The first track 121 and the second track 122 shown in FIG. 14 are each configured to extend in a straight line. In other embodiments, the first track 121 and the second track 122 may also be configured to extend along a curve or be configured to other types. This application does not limit this, as long as the first positioning component 110 can rotate and / or slide relative to the second positioning component 120, it is within the protection scope of this application.

[0037] Referring to Figures 15 and 16, the first positioning assembly 110 includes a rotating seat 114. The rotating seat 114 may be generally circular. The rotating seat 114 is located on the upper surface 123A of the base and has a relatively flat outer surface to facilitate sliding on the upper surface 123A of the base. The first positioning assembly 110 also includes a connecting seat 113 connected to the rotating seat 114. The connecting seat 113 may include a support portion 1131 and a connecting portion 1132. The connecting portion 1132 is connected to the rotating seat 114, and the support portion 1131 may be connected to the connecting portion 1132 or may be integrally formed. The support portion 1131 extends upwardly at an angle relative to the rotating seat 114. An open mounting space is formed between the support portion 1131 and the connecting portion 1132 for accommodating the carrier body 300 (see Figure 1). Specifically, the support portion 1131 and the connecting portion 1132 are set at an angle, for example, at an obtuse angle, and an installation space is formed between the support portion 1131 and the connecting portion 1132. The first positioning assembly 110 also includes a first slider 111 and a second slider 112. The first slider 111 is positioned from approximately the axial center of the rotating base 114 in a direction away from the connecting base 113, for example, extending from the relatively flat outer surface of the rotating base 114 in a direction away from the connecting base 113. In the extension direction from the front end to the rear end of the first positioning assembly 110, the second slider 112 is closer to the support portion 1131 relative to the first slider 111. The second slider 112 is closer to the rear end of the first positioning assembly 110 relative to the first slider 111. The second slider 112 may be located below the connecting portion 1132 and extends from the rotating base 114 in a direction away from the connecting base 113, for example, extending from the relatively flat outer surface of the rotating base 114 in a direction away from the support portion 1131. The first slider 111 and the second slider 112 can be rods, balls, or any other structure suitable for rotating and sliding on the first track 121 or the second track 122. The first slider 111 can slide along the first track 121, and the second slider 112 can slide along the second track 122, thereby giving the first positioning assembly 110 a rearward use mode and a lateral use mode on the second positioning assembly 120 (as shown in FIG. 16). As shown in FIG. 14, the grooves forming the first track 121 and the second track 122 terminate within the upper surface of the base 123, without exposing notches at the edge of the base 123 to form facing the left and right side doors of the vehicle, thereby preventing the first slider 111 and the second slider 112 from sliding out or detaching from the base 123. Furthermore, although Figures 14 and 15 show that the second positioning component 120 is provided with a track 120A and the first positioning component 110 is provided with a slider 110A, this application is not limited to this. This application may provide the first positioning component 110 with a track 120A and the second positioning component 120 with a slider 110A that can slide on the track 120A.

[0038] Referring to Figures 1, 8, and 9, the angle adjustment mechanism 200 is disposed on the first positioning component 110 and connected to the connecting seat 113 to adjust the tilt angle α of the connecting seat 113 relative to the rotating seat 114 (as shown in Figure 5 or Figure 6). This allows the angle between the connecting seat 113 and the vehicle body 300 mounted on the connecting seat 113 relative to the rotating seat 114 to switch between a first tilt angle (as shown in Figure 5) and a second tilt angle (as shown in Figure 6), thereby improving the user's riding comfort. When the first positioning component 110 rotates and slides relative to the second positioning component 120, the angle adjustment mechanism 200 can move with the first positioning component 110 relative to the second positioning component 120 on a plane parallel to the upper surface 123A of the second positioning component 120. For example, the first positioning component 110 can be adjusted to a side-facing mode, thereby facilitating the user, for example, to adjust the vertical height of the connecting seat 113 relative to the rotating disc 114 via the angle adjustment mechanism 200 from outside the vehicle door. Alternatively, after adjusting the tilt angle α of the vehicle body 300 relative to the second positioning component 120 outside the vehicle door, the first positioning component 110 is rotated and slid relative to the second positioning component 120, thereby adjusting the vehicle body 300 to a rearward use mode.

[0039] Referring to Figures 7 to 9, the connecting seat 113 may include a connecting seat upper cover 1133 and a connecting seat lower cover 1134 that engage with each other. The connecting seat 113 includes a connecting seat pivot portion 1132A, a first end of a rotating seat 114 is pivotally connected to the connecting seat pivot portion 1132A, and a second end of the rotating seat 114 (on the opposite side of the first end relative to the axis of the rotating seat 114) is movably connected to the angle adjustment mechanism 200. In one embodiment, the connecting portion 1132 has a first end and a second end. The first end of the connecting portion 1132 is farther away from the support portion 1131 relative to the second end of the connecting portion 1132, and the second end of the connecting portion 1132 is closer to the support portion 1131 relative to the first end of the connecting portion 1132. A connecting seat pivot portion 1132A is provided at the first end of the connecting portion 1132 away from the support portion 1131. The connecting seat pivot portion 1132A is pivotally connected to the rotating seat 114. The second end of the connecting portion 1132 near the support portion 1131 can rotate around the connecting seat pivot portion 1132A. The second end of the connecting portion 1132 can move relative to the rotating seat 114 in the vertical direction (vertical direction as shown in Figure 5). The angle adjustment mechanism 200 can be located in the internal space formed by the upper cover 1133 of the connecting seat, the lower cover 1134 of the connecting seat, and the rotating seat 114. Specifically, the angle adjustment mechanism 200 is connected to the connecting seat 113, so that the angle adjustment mechanism 200 can move with the movement of the connecting seat 113. Optionally, the angle adjustment mechanism 200 is connected to the second end of the connecting portion 1132 near the support portion 1131. When the connecting seat 113 is operated to move vertically relative to the rotating seat 114, the angle adjustment mechanism 200 can move vertically relative to the rotating seat 114 along with the connecting seat 113, thereby locking the second end of the connecting portion 1132 near the support portion 1131 at different heights relative to the rotating seat 114, so as to adjust the tilt angle α of the connecting seat 113 relative to the rotating seat 114. Furthermore, although the carrier body 300 is a baby carrier as shown in FIG. 1, in other embodiments, the carrier body 300 can also be other carrier devices, that is, the positioning component 100 can also be connected to other carrier devices through the connecting seat 113. For example, the carrier body 300 can be a booster seat, with the second positioning component 120 mounted on the car seat, the booster seat mounted on the connecting seat 113, and the angle adjustment mechanism 200 used to adjust the angle of the booster seat relative to the car seat.

[0040] Referring to Figures 8, 11, and 13, the angle adjustment mechanism 200 includes a locking member 240, and the rotating seat 114 includes a locking member receiving portion 1145. Optionally, the locking member receiving portion 1145 is disposed at the second end of the rotating seat 114. The locking member 240 can engage or disengage with the locking member receiving portion 1145. Specifically, the locking member 240 can be a rod, and the rotating seat 114 can be pivotally connected at its first end to the connecting seat pivot portion 1132A, while the rotating seat 114 has a locking member receiving portion 1145 protruding toward the connecting seat 113 at its second end opposite to the first end of the rotating seat 114. The locking member receiving portion 1145 may include two or more locking holes 1145A disposed along the vertical movement direction of the angle adjustment mechanism 200 relative to the rotating seat 114. As shown in Figure 8, the locking member receiving portion 1145 includes four locking holes 1145A, but is not limited thereto. The engaging member receiving portion 1145 may also take other forms, such as a groove, but is not limited thereto. When the engaging member receiving portion 1145 is provided with two or more engaging holes 1145A, the engaging member 240 can be inserted into engaging holes 1145A at different heights relative to the rotating seat 114, thereby causing the connecting seat 113 and the carrier body 300 connected to the connecting seat 113 to be at different tilt angles α relative to the rotating seat 114.

[0041] Referring to Figures 3, 5, and 8, these figures illustrate the locking position of the angle adjustment mechanism 200 on the connecting seat 113 when the connecting seat 113 is at a first tilt angle relative to the rotating seat 114. As shown in Figure 8, in one embodiment, for example, the engaging member 240 is inserted into the lowest height engaging hole 1145A on the engaging member receiving portion 1145. At this time, if the carrier body 300 is mounted on the connecting seat 113, the carrier body 300 is in a flat state. The term "flat state" refers to the state of the connecting seat 113 and the carrier body 300 mounted thereon when the tilt angle α of the connecting seat 113 relative to the rotating seat 114 is at its minimum. Referring to Figures 4, 6, and 9, these figures illustrate the locking position of the angle adjustment mechanism 200 on the connecting seat 113 when the connecting seat 113 is at a second tilt angle relative to the rotating seat 114. As shown in Figure 9, in one embodiment, for example, the engaging member 240 is inserted into the highest engaging hole 1145A on the engaging member receiving portion 1145. At this time, if the carrier body 300 is mounted on the connecting seat 113, the carrier body 300 is in an upright state. The term "upright state" refers to the state of the connecting seat 113 and the carrier body 300 mounted thereon when the tilt angle α of the connecting seat 113 relative to the rotating seat 114 is at its maximum. Although Figures 8 and 9 show the engaging positions of the engaging member 240 on the engaging member receiving portion 1145 when the connecting seat 113 is in a lying and upright state, respectively, the engaging member 240 can also be inserted into other engaging holes 1145A, thereby adjusting the connecting seat 113 to other tilt angles relative to the rotating seat 114. In one embodiment, the tilt angle α can be adjusted from 25 degrees to 70 degrees, for example, from 40 degrees to 50 degrees, by the angle adjustment mechanism 200. It should be noted that the first tilt angle and the second tilt angle in this application refer to the tilt angles of the connecting seat 113 relative to the rotating seat 114 in any two different tilt states within the adjustable range, and are not limited to the "lying state" and "standing state" mentioned above. It can be understood that the first tilt angle is smaller than the second tilt angle.

[0042] Referring to Figures 9 and 11, the angle adjustment mechanism 200 includes a drive mechanism 210. The drive mechanism 210 is connected to the connecting seat 114. Specifically, the drive mechanism 210 is connected to the second end of the connecting portion 1132 near the support portion 1131, and can move up and down relative to the rotating seat 114 with the second end near the support portion 1131. The drive mechanism 210 is driven connected to the engaging member 240 and can switch between a locked position and a unlocked position. When the drive mechanism 210 is in the locked position (as shown in Figure 11), the engaging member 240 engages with the engaging member receiving portion 1145. When the drive mechanism 210 is in the unlocked position (when the engaging member 240 shown in Figure 11 slides to the bottom of the drive groove 213B), the engaging member 240 is released from the engaging member receiving portion 1145. The drive mechanism 210 can be located in the internal space formed by the upper cover 1133 of the connecting seat, the lower cover 1134 of the connecting seat, and the upper housing 1143 of the rotating seat.

[0043] Figures 11 to 13 illustrate specific details of the drive mechanism 210 in the angle adjustment mechanism 200 at different angles in one embodiment of this application. The drive mechanism 210 includes a drive member 213, which is connected to the engaging member 240 and is movable relative to the connecting seat 113, thereby switching the drive mechanism 210 between a locked position and an unlocked position. For example, the drive member 213 can move up and down relative to the connecting seat 113 between the connecting seat 113 and the rotating seat 114, thereby enabling the engaging member 240 to engage or disengage with the engaging member receiving portion 1145. The drive member 213 may be provided with a drive groove 213B, and the engaging member 240 can be connected to the drive groove 213B by, for example, a drive pin (not shown) and slide within the drive groove 213B, thereby engaging or disengaging with the engaging member receiving portion 1145, thereby switching the drive mechanism 210 between a locked position and an unlocked position. The drive groove 213B has an inclined structure. The drive mechanism 210 may include a fixing member 211, which is connected to the connecting seat 113, for example, by adhesive bonding, mechanical fixing, welding, or other means, and is movable with the connecting seat 113. The fixing member 211 may be disposed in the lower cover 1134 of the connecting seat. The fixing member 211 includes a receiving cavity 211C, in which the drive member 213 is received and can slide within the receiving cavity 211C. The fixing member 211 may also be provided with a limiting hole 211B, which communicates with the receiving cavity 211C and opens toward the engaging receiving portion 1145. For example, the limiting hole 211B may extend from the receiving cavity 211C toward the engaging receiving portion 1145. The engaging member 240, as the driving member 213 moves, passes through the limiting hole 211B and inserts into the engaging member receiving portion 1145, or disengages from the engaging member receiving portion 1145 and retracts into the limiting hole 211B. Thus, the limiting hole 211B limits the engaging member 240, and the wall of the limiting hole 211B provides support for the engaging member 240. The driving mechanism 210 may also include a first reset member 212 disposed between the driving member 213 and the fixing member 211. The first reset member 212 is configured to bias the driving member 213 toward the locked position. The first reset member 212 may be an elastic member connected to the fixing member 211, such as a compression spring, tension spring, or sheet spring. The first reset member 212 may be accommodated in the receiving cavity 211C and configured to bias the driving member 213 toward the locked position. In particular, as shown in Figures 11 to 13, the driving member 213 may have a protrusion 213C formed on its outer surface facing the first reset member. The first reset member 212 is located within the receiving cavity 211C, and its first end is connected to the fixing member 211, and the protrusion 213C can be inserted into the second end of the first reset member 212. In this embodiment, the first reset member 212 can be a compression spring, and in other embodiments not shown, it can also be a tension spring or a spring sheet, and this application is not limited thereto.

[0044] Referring to Figures 2, 9, and 11, the angle adjustment mechanism 200 may include a release operation member 220. The release operation member 220 is disposed on the connecting seat 113 and connected to the drive member 213. The release operation member 220 can be operated to move the drive member 213 relative to the connecting seat 113. In one embodiment, the release operation member 220 may be located in a support portion 1131 of the connecting seat 113 that extends outward relative to the rotating seat 114. When the vehicle 1000 is installed in a car seat, since the release operation member 220 is disposed in the support portion 1131, the user can easily operate the angle adjustment mechanism 200 by means of the release operation member 220 disposed in the support portion 1131, thereby adjusting the tilt angle α of the vehicle 1000 relative to the second positioning component 120 to improve riding comfort.

[0045] See Figures 9, 11, and 12. The drive mechanism 210 of the angle adjustment mechanism 200 is housed in the internal space formed by the upper cover 1133 of the connecting seat, the lower cover 1134 of the connecting seat, and the rotating seat 114. The release operation member 220 includes a slider 222 located on the connecting seat 113, which is connected to the drive member 213 and slidably connected to the connecting seat 113. As shown in Figure 13, the slider 222 can be a square structure (or other structures). A handle 222B can be formed on the slider 222, and an opening 1131A is formed on the support portion 1131. The handle 222B is exposed outward from the internal space through the opening 1131A, thereby facilitating the user to control the drive mechanism 210 by means of the handle 222B. One of the slider 222 or the connecting seat 113 may include an adjustment limiting groove 222A, and the other of the slider 222 or the connecting seat 113 may include a first limiting member 1136. The first limiting member 1136 can pass through and slide within the adjusting limiting groove 222A. As shown in Figures 11 and 12, the slider 222 is provided with the adjusting limiting groove 222A, and the extending direction of the adjusting limiting groove 222A is approximately parallel to the extending direction of the support portion 1131 toward the connecting portion 1132. The connecting seat 113 is provided with the first limiting member 1136, and the first limiting member 1136 is a limiting pin whose two ends are respectively fixed to the upper cover 1133 and the lower cover 1134 of the connecting seat.

[0046] Referring to Figures 9, 12, and 13. The release operation member 220 may further include a second reset member 223, which is located between the slider 222 and the connecting seat 113 and configured to bias the slider 222 so that the slider 222 can slide when not operated, thereby allowing the drive member 213 to move to the locked position. The first end of the second reset member 223 is connected to the connecting seat 113, and the second end is connected to the slider 222. The second reset member 223 may be a compression spring, a tension spring, or a spring sheet, etc.

[0047] Referring to Figures 11 to 13, the angle adjustment mechanism 200 includes a traction member 230. A first end of the traction member 230 is connected to a drive member 213, and the other end is connected to a release operation member 220. The traction member 230 may include a steel wire 231 and a steel wire sheath 232. The first end of the steel wire 231 is connected to the release operation member 220. In one embodiment, the first end of the steel wire 231 is connected to a slider 222. The second end of the steel wire 231 is connected to the drive member 213. The steel wire sheath 232 is sleeved over the steel wire 231. The first end of the steel wire sheath 232 is connected to a fixing member 211. The fixing member 211 may have a sheath receiving portion 211A communicating with a receiving cavity 211C, for example, the sheath receiving portion 211A extends from the receiving cavity 211C toward the release operation member 220. This sheath receiving portion 211A allows the steel wire sheath 232 to be inserted and fixed therein. For example, the sheath receiving portion 211A can be in the form of a slot or a hole. The drive member 213 is provided with a wire receiving portion 213A. The wire receiving portion 213A can be in the form of a hook or hole for easy fixing of the wire 231. As shown in FIG11, the wire 231 starts from one end connected to the release operation member 220, extends through the first end of the wire sheath 232, and then connects to the wire receiving portion 213A via the receiving cavity 211C. The connecting seat 113 may also include a fixing cover 1135, to which the second end of the wire sheath 232 is connected. As shown in FIG11 to 13, the fixing cover 1135 is provided on the lower cover 1134 of the connecting seat. By connecting the first end of the wire sheath 232 to the fixing member 211 and connecting the second end of the wire sheath 232 to the fixing cover 1135, the wire sheath 232 is limited and fixed. A steel wire sheath 232 is fitted over the steel wire 231. When the steel wire is pulled, the sheath 232 acts as a track, facilitating the movement of the steel wire 231 and preventing it from getting tangled in other components. Furthermore, the sheath 232 can be bent and twisted freely to facilitate the arrangement of the steel wire 231. In some embodiments not shown, the second end of the steel wire 231 (connected to the release mechanism 220) can be directly driven by the first end of the steel wire 231, i.e., the sheath 232 may not be required.

[0048] Referring to Figures 7, 10, and 12, the rotary seat 114 includes a reinforcing member 1141. The reinforcing member 1141 includes a reinforcing member body 1141A, with a reinforcing member pivot portion 1141C formed at its first end. The reinforcing member pivot portion 1141C is pivotally connected to the connecting seat 113, for example, to the connecting seat pivot portion 1132A. The second end of the reinforcing member body 1141A (i.e., the end opposite to the first end of the reinforcing member body 1141A) is movably connected to the angle adjustment mechanism 200. Specifically, the second end of the reinforcing member body 1141A is provided with a locking member receiving portion 1145. The rotary seat 114 may include an upper rotary seat housing 1143 and a lower rotary seat housing 1144, which engage with each other and form a receiving cavity 1146 opening toward the connecting seat 113. In one embodiment, the rotating seat 114 may be generally disc-shaped, and the receiving cavity 1146 extends from the front end to the rear end of the rotating seat 114 (as shown in FIG3, in the rear-facing mode, the front end and rear end of the rotating seat 114 face the rear and front of the vehicle, respectively) in a manner suitable for accommodating the reinforcing body 1141A, and is located approximately midway between the left and right ends of the rotating seat 114 (as shown in FIG3, in the rear-facing mode, the left and right ends of the rotating seat 114 face the right-side door and left-side door of the vehicle, respectively). The reinforcing body 1141A is received in the receiving cavity 1146 and fixed to the lower housing 1144 of the rotating seat, for example, by screws, welding, or other means. The reinforcing body 1141A may be a flat, elongated metal plate or plastic plate, or may be made of other materials and have other shapes, but is not limited thereto. In one embodiment, the first and second ends of the reinforcing member body 1141A extend from the upper housing 1143 of the rotating seat toward the connecting seat 113, respectively. For example, the upper cover 1143 of the rotating seat has an opening 1143A on the side facing the connecting seat 113, and the first and second ends of the reinforcing member body 1141A extend from the opening 1143A and toward the connecting seat 113, respectively. In one embodiment, the reinforcing member pivot portion 1141C protrudes from the first end of the reinforcing member body 1141A and extends toward the connecting seat 113. One of the reinforcing member pivot portion 1141C and the connecting seat pivot portion 1132A of the connecting seat 113 (for example, connecting seat pivot portion 1132A as shown in FIG. 7) may include a pivot shaft 1132A', and the other includes a pivot hole 1141C' (for example, reinforcing member pivot portion 1141C as shown in FIG. 7). The pivot shaft 1132A' can be inserted into the pivot hole 1141C' and rotated, thereby enabling the connecting seat 113 to pivot relative to the rotating seat 114. The angle adjustment mechanism 200 includes a locking member 240, and a locking member receiving portion 1145 may be provided at the second end of the reinforcing member body 1141A (i.e., the other end opposite to the reinforcing member pivot portion 1141C) in the direction extending toward the connecting seat 113.The engaging member 240 can engage or disengage with the engaging member receiving portion 1145. The engaging member 240 can be a rod, and the engaging member receiving portion 1145 can include two or more engaging holes 1145A arranged along the direction from the reinforcing member body 1141A toward the connecting seat 113, as shown in FIG12, where the engaging member receiving portion 1145 includes four engaging holes 1145A. The engaging member receiving portion 1145 can also be in other forms, such as a groove, but is not limited thereto. Although not shown in the figures, when the present application includes the reinforcing member 1141, the sliding member 110A can also be disposed on the reinforcing member 1141, and extend from the reinforcing member 1141 through the lower housing 1144 of the rotating seat and in a direction away from the connecting seat 113. Introducing the reinforcing member 1141 into the rotating seat 114 enhances the connection strength between the connecting seat 113 and the rotating seat 114, while also improving the connection strength between the sliding member 110A and the second positioning assembly 120, thereby enhancing the safety of the vehicle being installed onto the positioning assembly 100. Referring to Figures 7, 8, and 10, the reinforcing member 1141 includes a connecting seat limiting groove 1141B. The connecting seat limiting groove 1141B is located between the first and second ends of the reinforcing member body 1141A and extends from the reinforcing member body 1141A toward the connecting seat 113. The connecting seat 113 is connected to and can slide within the connecting seat limiting groove 1141B. Specifically, referring to Figure 7, the connecting seat limiting groove 1141B extends from the reinforcing member body 1141A toward the connecting seat 113 and is located between the reinforcing member pivot portion 1141C and the engaging member receiving portion 1145. Referring specifically to Figure 8, the connecting portion 1132 of the connecting seat 113 includes a second limiting member 1132B, which is connected to and slides within the connecting seat limiting groove 1141B. In one embodiment, the second limiting member 1132B is a limiting pin whose two ends are respectively connected to the upper cover 1133 or the lower cover 1134 of the connecting seat.

[0049] Referring to Figures 7, 10, and 11, the reinforcing body 1141A has a width direction (as shown by the W direction in Figure 7) and a length direction (as shown by the L direction in Figure 7). Two reinforcing pivot portions 1141C are formed at the first end of the reinforcing body 1141A in the length direction, and the two reinforcing pivot portions 1141C are spaced apart in the width direction of the reinforcing body 1141A. Two engaging receiving portions 1145 are formed at the second end of the reinforcing body 1141A opposite to the first end in the length direction, and the two engaging receiving portions 1145 are spaced apart in the width direction. Two connecting seat limiting grooves 1141B are formed between the first end and the second end of the reinforcing body 1141A in the length direction, and the two connecting seat limiting grooves 1141B are spaced apart in the width direction. Each of the two reinforcing pivot portions 1141C has a pivot hole 1141C'. The connecting seat pivot portion 1132A includes two pivot shafts 1132A', each pivot shaft 1132A' being inserted into a corresponding pivot hole 1141C'. The connecting portion 1132 includes two second limiting members 1132B, each second limiting member 1132B being connected to a corresponding connecting seat limiting groove 1141B and sliding within the corresponding connecting seat limiting groove 1141B. The drive mechanism 210 is disposed between the two engaging member receiving portions 1145 and includes two engaging members 240, each engaging member 240 engaging or disengaging from a corresponding engaging member receiving portion 1145. Although the above description indicates that there are two reinforcing pivot portions 1141C, two engaging receiving portions 1145, and two connecting seat limiting grooves 1141B, it should be noted that in some other embodiments, this application may include other numbers of reinforcing pivot portions 1141C, two engaging receiving portions 1145, and two connecting seat limiting grooves 1141B.

[0050] Furthermore, although the angle adjustment mechanism 200 of this application includes a reinforcing member 1141 in this embodiment, those skilled in the art will understand that the angle adjustment mechanism 200 of this application may not include the reinforcing member 1141. When the angle adjustment mechanism 200 of this application does not include the reinforcing member 1141, the engaging member receiving portion 1145, the reinforcing member pivot portion 1141C, and the connecting seat limiting groove 1141B can be formed on the upper housing 1143 of the rotating seat. For example, engaging member receiving portion 1145 and reinforcing member pivot portion 1141C extending toward the connecting seat 113 are respectively provided at both ends of the upper housing 1143 of the rotating seat, so that the reinforcing member pivot portion 1141C is pivotally connected to the connecting seat pivot portion 1132A, and the engaging member receiving portion 1145 engages or disengages from the engaging member 240. A connecting seat limiting groove 1141B extending toward the connecting seat 113 is provided between the engaging receiving part 1145 and the reinforcing pivot part 1141C. The second limiting member 1132B passes through the connecting seat limiting groove 1141B and is slidably connected with the rotating seat 114.

[0051] Referring to Figures 3, 9 to 10, the rotating seat 114 includes an assisting member 1142, which is located between the pivot joint of the rotating seat 114 and the connecting seat 113 and the connection joint of the rotating seat 114 and the angle adjustment mechanism 200. A first end of the assisting member 1142 presses against the rotating seat 114, and a second end pushes against the connecting seat 113. In one embodiment, the assisting member 1142 is located between the reinforcing member pivot joint 1141C and the engaging member receiving joint 1145. In one embodiment, the assisting member 1142 can be fixed to the lower housing 1144 of the rotating seat. Specifically, the assisting member 1142 is fixed to the reinforcing member 1141. The assisting member 1142 can be a compression spring, a tension spring, or a spring sheet, preferably a compression spring. In the embodiment shown in Figure 3, the pivot point between the rotating seat 114 and the connecting seat 113 is located at the end where the reinforcing member pivot portion 1141C is located, while the center of gravity of the connecting seat 113 and the vehicle body 300 connected thereto (see Figure 1) is closer to the other end where the angle adjustment mechanism 200 is located (the end where the engaging member receiving portion 1145 is located). Thus, it is more strenuous for the user to adjust the connecting seat 113 upwards. The presence of the assist member 1142 can assist in lifting the connecting seat 113, making it easier for the user to adjust the tilt angle of the connecting seat 113 and the vehicle body 300 connected thereto relative to the rotating seat 114. Furthermore, when the connecting seat 113 is adjusted downwards relative to the rotating seat 114, the assist member 1142 can also provide a shock absorption effect. The assist member 1142 can provide a certain damping force when the connecting seat 113 and the vehicle body 300 connected thereto move downwards, making the downward adjustment of the tilt angle of the connecting seat 113 relative to the rotating seat 114 more controllable and safe. Although the assistive element 1142 is shown in the figures, it is not necessary, and this application can be implemented without the assistive element 1142. Refer to Figures 2, 11, and 16. The angle adjustment mechanism 200 can adjust the vehicle body 300 relative to the rotating seat 114 from a first tilt angle to a second tilt angle different from the first tilt angle. The vehicle body 300 is mounted on the positioning assembly 100, at which time the vehicle body 300 is at the first tilt angle relative to the rotating seat 114 (as shown in Figure 5). When it is necessary to adjust the tilt angle of the vehicle body 300 relative to the rotating seat 114 to a larger second tilt angle (as shown in Figure 6, for example, adjusting the vehicle body 300 to an upright position), the rotating seat 114 is rotated relative to the second positioning assembly 120 to a side-facing use mode, thereby allowing the tilt angle of the connecting seat 113 relative to the rotating seat 114 to be adjusted from the side (e.g., outside the vehicle door). The user can also adjust the up-and-down movement of the connecting seat 113 relative to the rotating seat 114 directly without rotating the rotating seat 114, while the vehicle body 300 is in a rear-facing use mode.The user can grip the handle 222B and apply force to it to make the slider 222 slide upward relative to the connecting seat 113. This causes the driving member 213 to move upward via the traction member 230 connected to the slider 222. The driving member 213, pulled by the traction member 230, causes the engaging member 240 to slide along the driving groove 213B, thereby disengaging the engaging member 240 from one of the engaging holes 1145A of the engaging member receiving part 1145 and retracting it into the limiting hole 211B, thus switching the driving mechanism 210 to the unlocked position. At this time, the first reset member 212 is compressed. After the drive mechanism 210 is switched to the unlock position, the user can lift the second end (or support 1131) of the connecting seat 113 with the assistance of the assist member 1142. The second limiting member 1132B slides along the connecting seat limiting groove 1141B (see Figure 9). When the second end (or support 1131) of the connecting seat 113 is lifted to an appropriate height (e.g., from the lowest point to the highest point of the connecting seat limiting groove 1141B and some height in between), the engaging member 240 aligns with another engaging hole 1145A of the engaging member receiving part 1145. When the user releases their hand from the handle 222B, the restoring force of the first reset member 212 causes the drive member 213 to slide towards the locked position. The driving engaging member 240 slides along the drive groove 213B, extends out of the limiting hole 211B, and inserts into another engaging hole 1145A. At this time, the drive mechanism 210 is switched to the locked position, and the vehicle body 300 is at a second tilt angle relative to the rotating seat 114.

[0052] Referring again to Figures 2, 11, and 16. The vehicle body 300 is mounted on the positioning assembly 100, at which point the vehicle body 300 is at a second tilt angle relative to the rotating seat 114 (as shown in Figure 6). When it is necessary to adjust the tilt angle of the vehicle body 300 relative to the rotating seat 114 to a smaller first tilt angle (as shown in Figure 5, for example, adjusting the vehicle body 300 to a flat position), the rotating seat 114 is rotated relative to the second positioning assembly 120 to a side-facing use mode, thereby allowing the up-and-down movement of the connecting seat 113 relative to the rotating seat 114 to be adjusted from the side (e.g., outside the vehicle door). The user can also adjust the up-and-down movement of the connecting seat 113 relative to the rotating seat 114 directly without rotating the rotating seat 114, while the vehicle body 300 is in a rear-facing use mode. The user can grip the handle 222B and apply force to the handle 222B to make the slider 222 slide upward relative to the connecting seat 113, thereby driving the drive member 213 upward through the traction member 230 connected to the slider 222. As the traction member 230 moves, the driving member 213 drives the engaging member 240 to slide along the driving groove 213B, thereby causing the engaging member 240 to disengage from one of the engaging holes 1145A in the engaging member receiving part 1145 and retract into the limiting hole 211B, thus switching the driving mechanism 210 to the unlocking position. At this time, the first reset member 212 is compressed. After the driving mechanism 210 switches to the unlocking position, the user can lower the second end (or support part 1131) of the connecting seat 113 to a certain height (for example, from the highest point to the lowest point of the connecting seat limiting groove 1141B and a certain height in between), at which time the engaging member 240 is aligned with the other engaging hole 1145A on the engaging member receiving part 1145. When the user releases their hand from the handle 222B, the restoring force of the first reset member 212 causes the drive member 213 to slide towards the locked position, and drives the engaging member 240 to slide along the drive groove 213B, pass through the limiting hole 211B, and insert into another engaging hole 1145A of the engaging member receiving part 1145. At this time, the drive mechanism 210 switches to the locked position, and the vehicle body 300 is at a first tilt angle relative to the rotating base 114.

[0053] It should be noted that in this application, the vehicle body 300 includes any one of an infant carrier, seat, sleeping box, or pet carrier for carrying animals. The above embodiments and accompanying drawings of this application illustrate an infant carrier-type car seat as an example, which is generally used for smaller infants (e.g., weighing less than 18 kg). The infant carrier-type car seat can be rotated to a "rear-facing mode" and a "side-facing mode." In some embodiments, the vehicle body 300 may also be a non-carrier-type car seat, suitable for larger children, which can be rotated to a "forward-facing mode," a "rear-facing mode," and a "side-facing mode."

[0054] The above embodiments only illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims. [Simplified Explanation of the Diagram]
