[0054] Figure 3 , Figure 4 and Figure 11A perspective view of a carrier 1000 according to an embodiment of the present invention and an angle adjustment mechanism 200 according to an embodiment of the present invention are schematically shown. The carrier 1000 includes a positioning component 100, an angle adjustment mechanism 200 according to an embodiment of the present invention, and a carrier body 300. The positioning component 100, the angle adjustment mechanism 200, and the carrier body 300 will be described below concurrently with the description of the carrier 1000. The carrier 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 carrier 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.

[0055] Figures 1 to 4 A perspective view of a carrier 1000 according to an embodiment of the present invention is shown schematically. The carrier body 300 can be connected to the positioning assembly 100. Figures 4 to 5 Figures 1 and 16 schematically illustrate a positioning assembly according to an embodiment of the present invention. 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.

[0056] refer to Figure 2 , Figure 5 and Figure 6 The positioning assembly 100 can be secured to the vehicle seat, for example, using ISOFIX connectors. The positioning assembly 100 includes a first positioning assembly 110 and a second positioning assembly 120. The first positioning assembly 110 can be connected to the vehicle body 300. Figure 1As shown, the vehicle body 300 is mounted on the connector 113 of the first positioning assembly 110. The second positioning assembly 120 can be connected to a car seat. In one embodiment, the second positioning assembly 120 is provided with an ISOFIX connector 124A and a support leg 124B. The ISOFIX connector 124A is located approximately at the rear end of the second positioning assembly 120, and the support leg 124B is located approximately at the front end of the second positioning assembly 120. Specifically, when the second positioning assembly 120 is mounted on a car seat, the ISOFIX connector 124A is used to securely connect the second positioning assembly 120 to the car seat, and the support leg 124B is used to abut against the floor inside the vehicle. With the connection and support of the ISOFIX connector 124A and the support leg 124B, the second positioning assembly 120 can be stably installed inside the car. For example, Figures 2 to 4 The vehicle 1000 shown is in "rear-facing use mode". "Rear-facing use mode" refers to a mode where, when the positioning component 100 is installed in a car seat, with the car as a reference, the user's face faces the rear of the car when sitting on the vehicle body 300. In this mode, the front end of the first positioning component 110 faces the rear of the car, and the rear end of the first positioning component 110 faces the front of the car. The vehicle 1000 or the positioning component 100 can also be adjusted to a "side-facing use mode" (e.g., Figure 16 (As shown). The so-called "lateral use mode" is a mode in which, when the positioning component 100 is installed in a car seat, with the car as a reference, the user sits on the vehicle body 300 with their face facing the car 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 figure, the vehicle 1000 can also be in a "forward use mode". The so-called "forward use mode" is a mode in which, when the positioning component 100 is installed in a car seat, with the car as a reference, the user sits on the vehicle body 300 with their face facing the front of the car, and the rear end of the first positioning component 110 faces the rear of the car, while the front end of the first positioning component 110 faces the front of the car. The following description uses the vehicle 1000 in a "rearward use mode" as an example to illustrate this invention. Those skilled in the art will understand that the vehicle 1000 and the positioning component 100 of this invention can be used in either a "lateral use mode" or a "forward use mode".

[0057] refer 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 (e.g., Figure 14 The second positioning component 120 shown is provided with a track 120A, and the other (such as...) Figure 15The first positioning component 110 shown is provided with a slider 110A, which can rotate and slide along the track 120A, so that the first positioning component 110 has a rearward use mode and a side use mode on the second positioning component 120.

[0058] refer to Figure 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 side of the base 123 facing the right side door of the car is the right side of the base 123. Figure 14 As shown, the first track 121 can be located in the upper surface 123A of the base, between the front end and the rear end of the base 123, and extends from the left side to the right side of the base 123. For example... Figure 14 As shown, the first track 121 can be located approximately midway between the front and rear ends of the base 123. The second track 122 is a T-shaped groove formed in the upper surface 123A of the base, intersecting the first track 121. Figure 14 As shown, 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. Figure 14 The first track 121 and the second track 122 shown are each configured to extend along 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 in other types. This application does not limit this, as long as the rotation and / or sliding of the first positioning component 110 relative to the second positioning component 120 can be achieved, it is within the protection scope of this application.

[0059] refer to Figure 15 and 16The first positioning component 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 component 110 also includes a connecting seat 113, which is 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 allowing the first positioning assembly 110 to have a rearward use mode and a lateral use mode on the second positioning assembly 120 (e.g., ...). Figure 16 As shown). Figure 14 As shown, the grooves forming the first track 121 and the second track 122 terminate within the upper surface of the base 123, without exposing the edges of the base 123 to form notches 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... Figure 14 and Figure 15The diagram shows that the second positioning component 120 is provided with a track 120A, and the first positioning component 110 is provided with a slider 110A. However, the present invention is not limited to this. The present invention 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.

[0060] See Figure 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 (e.g., Figure 5 or Figure 6 ), such that the angle between the connecting seat 113 and the vehicle body 300 mounted on the connecting seat 113 and the rotating seat 114 is at a first tilt angle (e.g. Figure 5 ) and second tilt angle (e.g. Figure 6 The angle adjustment mechanism 200 can switch between the first positioning component 110 and the second positioning component 120, 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 along 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, making it easier for the user to adjust the vertical height of the connecting seat 113 relative to the rotating disk 114 via the angle adjustment mechanism 200, for example, 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 can be rotated and slid relative to the second positioning component 120 to adjust the vehicle body 300 to a rear-facing mode.

[0061] See Figures 7 to 9The 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. The 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, and 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 part 1132 can be positioned relative to the rotating seat 114 in the vertical direction (e.g.) Figure 5 The angle adjustment mechanism 200 can be located in the internal space formed by the upper cover 1133, the lower cover 1134, 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 part 1132 near the support part 1131. When the connecting seat 113 is operated to move in the vertical direction relative to the rotating seat 114, the angle adjustment mechanism 200 can move up and down relative to the rotating seat 114 with the connecting seat 113, thereby locking the second end of the connecting part 1132 near the support part 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. In addition, although as shown Figure 1 As shown, the carrier body 300 is an infant carrier. 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 via the connecting seat 113. For example, the carrier body 300 can be a booster seat, with the second positioning component 120 installed on the car seat, the booster seat installed 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.

[0062] See Figure 8 , 11In section 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, the rotating seat 114 can be pivotally connected at its first end to the connecting seat pivot portion 1132A, and 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 up-and-down movement direction of the angle adjustment mechanism 200 relative to the rotating seat 114. Figure 8 As shown, the engaging member receiving portion 1145 includes four engaging holes 1145A, but is not limited thereto. The engaging member receiving portion 1145 may also be in other forms, such as grooves, 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.

[0063] See Figure 3 , Figure 5 and Figure 8 These figures illustrate the locked 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. Figure 8 As shown, 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 lying-flat state. The term "lying-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. See also... Figure 4 , Figure 6 and Figure 9 These figures show the locked position of the angle adjustment mechanism 200 on the connecting seat 113 when the connecting seat 113 is at the second tilt angle relative to the rotating seat 114. Figure 9 As shown, in one embodiment, for example, the engaging member 240 is inserted into the engaging hole 1145A at its highest point 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... Figure 8 and Figure 9 The image shows the engagement positions of the engaging member 240 on the engaging member receiving portion 1145 when the connecting seat 113 is in a lying position and an upright position. The engaging member 240 can also be inserted into other engaging holes 1145A to adjust 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 using the angle adjustment mechanism 200, for example, from 40 degrees to 50 degrees. 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 aforementioned "lying position" and "upright position." It is understood that the first tilt angle is smaller than the second tilt angle.

[0064] refer to Figure 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 drivenly 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 (e.g., when...), Figure 11 As shown), the engaging member 240 engages with the engaging member receiving part 1145. When the drive mechanism 210 is in the unlocked position ( Figure 11 When the locking member 240 is slid to the bottom of the drive groove 213B, the locking member 240 is released from the locking member receiving part 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.

[0065] Figures 11 to 13Specific details of the drive mechanism 210 in the angle adjustment mechanism 200 at different angles are shown in one embodiment of the present invention. 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, and 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 can support 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 can be an elastic member connected to the fixing member 211, such as a compression spring, tension spring, or spring sheet. The first reset member 212 can be received in the receiving cavity 211C and configured to bias the driving member 213 toward the locked position. In particular, as... Figures 11 to 13 As shown, 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 may be a compression spring, and in other embodiments not shown, it may also be a tension spring or a spring sheet; this application is not limited thereto.

[0066] refer to Figure 2 , Figure 9 and Figure 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 outwardly relative to the rotating seat 114. When the vehicle 1000 is installed in a car seat, because 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.

[0067] See Figure 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, the slider 222 being connected to the drive member 213 and slidably connected to the connecting seat 113. Figure 13 As shown, the slider 222 can be square (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, thus facilitating user control of the drive mechanism 210 via 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 adjustment limiting groove 222A. Figure 11 and 12 As shown, the slider 222 is provided with an adjustment limiting groove 222A, and the extension direction of the adjustment limiting groove 222A is approximately parallel to the extension direction of the support part 1131 toward the connecting part 1132. The connecting seat 113 is provided with a 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.

[0068] refer to Figure 9 , 12And 13. The release mechanism 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.

[0069] refer 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 may be in the form of a slot or a hole. The driving component 213 is provided with a wire receiving part 213A. The wire receiving part 213A can be in the form of a hook or hole for easy fixing of the wire 231. Figure 11 As seen, the steel wire 231 starts from one end connected to the release operating member 220, extends through the first end of the steel wire sheath 232, and then connects to the steel wire receiving part 213A via the receiving cavity 211C. The connecting seat 113 may also include a fixing cover 1135, to which the second end of the steel wire sheath 232 is connected. Figures 11 to 13 As shown, a fixing cover 1135 is disposed on the lower cover 1134 of the connecting seat. The steel wire sheath 232 is limited and fixed by connecting the first end of the steel wire sheath 232 to the fixing member 211 and the second end of the steel wire sheath 232 to the fixing cover 1135. When the steel wire sheath 232 is fitted onto the steel wire 231, it acts as a track when the steel wire is pulled, facilitating the pulling of the steel wire 231 without it getting tangled in other components. Furthermore, the steel wire 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 operation member 220) can be directly driven by the first end of the steel wire 231 (the end connected to the release operation member 220), meaning the steel wire sheath 232 may not be required.

[0070] refer to Figure 7 , Figure 10 and Figure 12 The rotating base 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 base 113, for example, to the connecting base 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 rotating base 114 may include an upper rotating base housing 1143 and a lower rotating base housing 1144, which engage with each other and form a receiving cavity 1146 opening toward the connecting base 113. In one embodiment, the rotating base 114 may be generally disk-shaped, and the receiving cavity 1146 extends from the front end to the rear end of the rotating base 114 (e.g., ...). Figure 3 As shown in the rearward use mode, the front and rear ends of the rotating seat 114 extend in a manner suitable for accommodating the reinforcing body 1141A, respectively, and are located at the left and right ends of the rotating seat 114 (e.g., Figure 3 As shown in the rear-facing usage mode, the left and right ends of the rotating seat 114 are positioned approximately at the center of the vehicle (the right and left doors are respectively facing the vehicle's right and left doors). The reinforcing body 1141A is received in the accommodating 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 can be a flat, elongated metal plate or plastic plate, or it can 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 body 1141A extend from the upper housing 1143 of the rotating seat toward the connecting seat 113, respectively. For example, the upper housing 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 body 1141A extend from the opening 1143A and toward the connecting seat 113, respectively. In one embodiment, the reinforcing pivot portion 1141C protrudes from a first end of the reinforcing body 1141A and extends toward the connecting seat 113. The reinforcing pivot portion 1141C and one of the connecting seat pivot portions 1132A of the connecting seat 113 (e.g., as...) Figure 7 The connecting seat pivot portion 1132A shown may include a pivot shaft 1132A', and another may include a pivot hole 1141C' (e.g., as shown in the figure). Figure 7The diagram shows the reinforcing pivot portion 1141C). The pivot shaft 1132A' can be inserted into the pivot hole 1141C' and rotated, thereby allowing 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 can be provided at the second end of the reinforcing body 1141A (i.e., the other end opposite to the reinforcing pivot portion 1141C) extending toward the connecting seat 113. The locking member 240 can engage or disengage with the locking member receiving portion 1145. The locking member 240 can be a rod, and the locking member receiving portion 1145 can include two or more locking holes 1145A provided along the direction from the reinforcing body 1141A toward the connecting seat 113, such as... Figure 12 As shown, 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 grooves, but is not limited thereto. Although not shown in the figures, when the present invention includes a 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 can enhance 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 carrier being installed onto the positioning assembly 100. (Reference) Figure 7 , 8 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, which is connected to and can slide within the connecting seat limiting groove 1141B. See details. 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. See details. 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.

[0071] refer to Figure 7 , 10 And 11, the main body of the reinforcing member 1141A has a width direction (such as...) Figure 7 (as shown in the W direction) and the length direction ... Figure 7As shown in the L direction, two reinforcing member pivot portions 1141C are formed at the first end of the reinforcing member body 1141A in the length direction, and the two reinforcing member pivot portions 1141C are spaced apart in the width direction of the reinforcing member body 1141A. Two engaging member receiving portions 1145 are formed at the second end of the reinforcing member body 1141A opposite to the first end in the length direction, and the two engaging member 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 member 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 member pivot portions 1141C forms a pivot hole 1141C', and the connecting seat pivot portion 1132A includes two pivot shafts 1132A', each pivot shaft 1132A' being inserted into the corresponding pivot hole 1141C'. The connecting portion 1132 includes two second limiting members 1132B, each second limiting member 1132B being connected to and sliding within a corresponding connecting seat limiting groove 1141B. The driving mechanism 210 is disposed between two engaging member receiving portions 1145 and includes two engaging members 240, each engaging or disengaging from a corresponding engaging member receiving portion 1145. Although the above description indicates that the number of reinforcing pivot portions 1141C, engaging member receiving portions 1145, and connecting seat limiting grooves 1141B is two, it should be noted that in some other embodiments, this invention may include other numbers of reinforcing pivot portions 1141C, engaging member receiving portions 1145, and connecting seat limiting grooves 1141B.

[0072] Furthermore, although the angle adjustment mechanism 200 of the present invention includes a reinforcing member 1141 in this embodiment, those skilled in the art will understand that the angle adjustment mechanism 200 of the present invention may not include the reinforcing member 1141. When the angle adjustment mechanism 200 of the present invention 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 portions 1145 and reinforcing member pivot portions 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.

[0073] refer to Figure 3 , 9 to Figure 10The 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. Figure 3 In the illustrated embodiment, the pivot joint between the rotating seat 114 and the connecting seat 113 is located at the end where the reinforcing pivot portion 1141C is located, while the connecting seat 113 and the carrier body 300 connected thereto (see...) Figure 1 The center of gravity of the connecting seat 113 is closer to the other end where the angle adjustment mechanism 200 is located (the end where the engaging receiving part 1145 is located). Therefore, it is more difficult for the user to adjust the connecting seat 113 upwards. The presence of the assisting component 1142 helps to lift the connecting seat 113, making it easier for the user to adjust the tilt angle of the connecting seat 113 and the connected vehicle body 300 relative to the rotating seat 114. Furthermore, the assisting component 1142 also provides shock absorption when the connecting seat 113 is adjusted downwards relative to the rotating seat 114. The assisting component 1142 can provide a certain damping force to the connecting seat 113 and the connected vehicle body 300 when they 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 assisting component 1142 is shown in the figure, it is not necessary, and this invention can be implemented without the assisting component 1142. Reference Figure 2 , Figure 11 and Figure 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 point the vehicle body 300 is at the first tilt angle relative to the rotating seat 114 (e.g., ...). 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 (such as...) Figure 6For example, when the vehicle body 300 is adjusted to an upright position, the rotating seat 114 is rotated relative to the second positioning component 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 cause the slider 222 to slide upward relative to the connecting seat 113, thereby driving the drive member 213 upward via the traction member 230 connected to the slider 222. As the traction member 230 pulls the drive member 213, the engaging member 240 slides along the drive groove 213B, causing the engaging member 240 to disengage from one of the engaging holes 1145A of the engaging member receiving part 1145 and retract into the limiting hole 211B, thereby switching the drive mechanism 210 to the unlocking position. At this time, the first reset member 212 is compressed. After the drive mechanism 210 switches to the unlocking position, the user can lift the second end (or support part 1131) of the connecting seat 113 with the assistance of the assist member 1142, and the second limiting member 1132B moves along the limiting groove 1141B of the connecting seat (see...). Figure 9 When the second end (or support 1131) of the connecting seat 113 is raised 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's hand is released from the handle 222B, the restoring force of the first reset member 212 causes the drive member 213 to slide towards the locked position, driving the engaging member 240 to slide along the drive groove 213B, extending out of the limiting hole 211B and inserting into the other engaging hole 1145A. At this time, the drive mechanism 210 switches to the locked position, and the vehicle body 300 is at a second tilt angle relative to the rotating seat 114.

[0074] See also Figure 2 , Figure 11 and Figure 16 The vehicle body 300 is mounted on the positioning assembly 100. At this time, the vehicle body 300 is at a second tilt angle relative to the rotating seat 114 (e.g., 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 (such as...) Figure 5When the vehicle body 300 is in a flat position (e.g., when the vehicle body 300 is adjusted to a lying position), the rotating seat 114 is rotated relative to the second positioning component 120 to a side-facing use mode, thereby allowing the vertical movement of the connecting seat 113 relative to the rotating seat 114 to be adjusted from the side (e.g., outside the vehicle door). Alternatively, the user can adjust the vertical 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 cause the slider 222 to slide upward relative to the connecting seat 113, thereby driving the drive member 213 upward via the traction member 230 connected to the slider 222. As the traction member 230 moves, the drive member 213 drives the engaging member 240 to slide along the drive groove 213B, causing the engaging member 240 to disengage from one of the engaging holes 1145A of the engaging member receiving part 1145 and retract into the limiting hole 211B, thus switching the drive mechanism 210 to the unlocking position. At this time, the first reset member 212 is compressed. After the drive mechanism 210 switches to the unlock position, the user can lower the second end (or support 1131) of the connecting seat 113 to a certain height (e.g., 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 another engaging hole 1145A on the engaging member receiving part 1145. When the user's hand is released 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 the other 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 seat 114.

[0075] 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, which is generally used for smaller infants (e.g., weighing less than 18 kg). This 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 older children, which can be rotated to a "forward-facing mode," a "rear-facing mode," and a "side-facing mode."

[0076] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
