Description

Technical Field

[0001] This application relates to the field of child safety seat technology, and more particularly to an adjustment mechanism and a child safety seat. Background Technology

[0002] Child car seats are designed specifically for children of different ages, installed in cars, and effectively improve children's safety while traveling. In the event of a collision or sudden deceleration, they reduce the impact force on children and restrict their body movement, thus minimizing injury and ensuring their safety while traveling.

[0003] To provide a more comfortable riding environment for children, child safety seats are generally equipped with angle adjustment devices, but traditional seat angle adjustment devices are prone to displacement and have poor reliability. Summary of the Invention

[0004] This application provides an adjustment mechanism and a child safety seat, which solves the problems of easy displacement and poor reliability of the adjustment mechanism.

[0005] In a first aspect, embodiments of this application provide an adjustment mechanism for use in a child safety seat, connected between the seat and the base of the child safety seat, for adjusting the position of the seat relative to the base, wherein the base has a plurality of adjustment holes spaced apart along a first direction, and the adjustment mechanism includes:

[0006] Base plate, for mounting to the chair seat;

[0007] A locking component includes a locking part and a driving part. The driving part has a mounting hole extending in a second direction. One end of the locking part is disposed in the mounting hole. The second direction is parallel to the axis of the adjusting hole.

[0008] An adjusting plate is movably connected to the base plate along the first direction. The adjusting plate is connected to the driving unit and is used to drive the locking member to move along the second direction when moving relative to the base plate along the first direction, so that the locking part can be inserted into different adjusting holes.

[0009] The beneficial effects of this application embodiment are as follows: The locking member is designed to include a locking part and a driving part. The extension direction of the mounting hole of the driving part is consistent with the extension direction of the hole axis of the adjustment hole, so that the position of the locking part located in the mounting hole can also be parallel to the hole axis of the adjustment hole. In this way, when the adjustment plate drives the locking member to move, the locking part can be inserted into different adjustment holes more smoothly, improving the operational convenience of the adjustment mechanism and allowing users to adjust the angle of the child safety seat more conveniently and effortlessly. Since the adjustment plate moves along the first direction and the locking member moves along the second direction, and the first and second directions are set at an angle, the locking part and the adjustment plate are connected through the driving part. When the adjustment plate moves, it first drives the driving part to move, and the driving part then drives the locking part to move. There is a motion transmission process. Compared with the adjustment plate directly driving the locking part to move, it avoids the lock part from being easily damaged by directly pulling it. At the same time, the locking part passes through the mounting hole of the driving part, and the contact area with the driving part is larger, which strengthens the stability of the locking part and makes it less likely to shake when the locking part is inserted into the adjustment hole, greatly improving the reliability of the adjustment mechanism.

[0010] In some embodiments, the driving part includes a driving section and a mounting section. The mounting section has a mounting hole. The driving section is connected to the adjusting plate. The locking part includes a first locking section, a mating section, and a second locking section. The mating section is located in the mounting hole. The first locking section is connected to the end of the mating section near the driving section and abuts against the surface of the mounting section near the driving section. The second locking section is connected to the end of the mating section away from the driving section. The second locking section is used to be inserted into different adjusting holes under the drive of the adjusting plate.

[0011] Based on the above embodiments, the locking part is designed to include a first locking section, a mating section, and a second locking section. The first locking section abuts against the surface of the mounting section near the driving section, making the connection between the locking part and the driving part more secure, so that the locking part is not easy to fall off, thus improving the reliability of the adjustment mechanism.

[0012] In some embodiments, the mounting segment includes:

[0013] The mounting body is connected to the drive segment and has the mounting holes;

[0014] The elastic claw is located on the side of the mounting body near the drive section, with one end connected to the mounting body and the other end extending in a direction away from the mounting body and close to the axis of the mounting hole. The first locking section abuts against the surface of the elastic claw near the drive section.

[0015] Based on the above embodiments, by setting an elastic claw with the other end of the elastic claw in a contracted state, the first locking segment first passes through the mounting hole, and then the contracted end of the elastic claw is squeezed to deform so that the first locking segment can pass through. When the first locking segment is completely inserted outside the elastic claw, the elastic claw returns to the contracted state to clamp the mating end. At the same time, the surface of the elastic claw near the drive segment abuts against the first locking segment to fix the locking part to the drive part. This design ensures the reliability of the connection between the locking part and the drive part, and facilitates the assembly of the locking part and the drive part.

[0016] In some embodiments, the adjusting plate has a first guide groove whose extension direction is at an angle to both the first direction and the second direction, and the driving part is provided with a guide post located in the first guide groove, so that when the adjusting plate moves relative to the base plate in the first direction, the guide post moves in the second direction under the guidance of the first guide groove, so that the locking member can be inserted into different adjusting holes.

[0017] Based on the above embodiments, when the adjustment mechanism is in the locked state, the guide post is located in the first guide groove of the adjustment plate near the adjustment hole, and one end of the locking member is located in an adjustment hole. When the adjustment mechanism is released from the locked state, the adjustment plate moves along the first direction, and the guide post moves away from the adjustment hole under the guidance of the first guide groove. At the same time, the drive unit drives the locking member to move away from the adjustment hole, so that the locking member moves out of the adjustment hole. At this time, the seat can be slid to adjust the angle of the seat relative to the base. After adjusting to the required angle, the adjustment plate moves back to the original position along the first direction, the guide post returns to the first guide groove near the adjustment hole, and one end of the locking member is located in the adjustment hole corresponding to the required angle, thus completing the angle adjustment of the child safety seat. This design makes the overall structure of the adjustment mechanism simple, the working principle simple and easy to operate, and facilitates subsequent inspection and maintenance.

[0018] In some embodiments, the base plate is provided with a second guide groove extending along the second direction. The groove wall of the second guide groove includes a first wall and a second wall extending along the second direction and facing away from each other. The driving part abuts between the first wall and the second wall. The inner wall of the second guide groove also includes a third wall perpendicular to the second direction and facing the driving part. When the locking part is located in the adjustment hole, the driving part abuts against the third wall.

[0019] Based on the above embodiments, by providing a second guide groove extending along the second direction, the driving part located in the guide groove can only move along the second direction, that is, along the direction parallel to the axis of the adjustment hole. At the same time, the locking part connected to the driving part can also only move along the second direction, thus preventing the driving part from deviating from the second direction and causing the locking part to be unable to smoothly insert into or move out of the adjustment hole, thereby enhancing the operational reliability of the adjustment mechanism.

[0020] In some embodiments, the adjusting plate is provided with a third guide groove extending along the first direction, the base plate is provided with a mounting post located within the third guide groove, and the adjusting mechanism further includes:

[0021] An elastic element extends along the first direction, with one end of the elastic element connected to the mounting post on the base plate and the other end connected to the adjusting plate.

[0022] In some embodiments, the adjusting plate is provided with a hook, and the elastic element includes:

[0023] A spring extending along the first direction and having one end connected to the mounting post on the base plate;

[0024] A connecting ring is attached to the end of the spring furthest from the mounting post and is hung on the hook.

[0025] Based on the above embodiments, the elastic element is designed to include a spring and a connecting ring. The connecting ring can be directly hung on the hook of the adjusting plate, making the assembly of the elastic element and the adjusting plate simpler and more convenient. When the elastic element is damaged, it is also easy to disassemble and replace the elastic element.

[0026] Secondly, embodiments of this application provide a child safety seat, including the adjustment mechanism, the base, and the seat as described above.

[0027] The child safety seat of this application embodiment greatly improves the reliability of the adjustment mechanism by designing the locking part of the adjustment mechanism to include a locking part and a driving part, thereby improving the adjustment stability of the child safety seat, and at the same time enabling users to adjust the angle of the child safety seat more conveniently and effortlessly.

[0028] In some embodiments, the base includes:

[0029] Base body; and

[0030] The mounting bracket is connected to the base body and has multiple adjustment holes.

[0031] Based on the above embodiments, the base is designed to include a base body and a mounting bracket. The chair is installed on the base through the connection of the adjustment mechanism and the mounting bracket, so that the base and the chair can be completely separated, and the chair can be installed on the base in either the forward or reverse direction, giving users more choices in usage.

[0032] In some embodiments, the mounting bracket has a first sliding groove extending along the first direction, and the adjustment mechanism further includes:

[0033] A side plate, connected to the base plate and disposed opposite to the mounting bracket, the side plate having a second sliding groove extending along the first direction;

[0034] A first sliding rod extends along the second direction, with one end of the first sliding rod connected to the side plate and the other end passing through the first sliding groove;

[0035] A fixing rod extends along the second direction, connects to the mounting bracket, and passes through the second sliding groove.

[0036] Based on the above embodiments, by setting a first sliding rod and a fixed rod, one end of the first sliding rod is connected to the side plate, and the other end passes through the first sliding groove of the mounting bracket. The fixed rod is connected to the mounting bracket and passes through the second sliding groove of the side plate, making the connection between the adjustment mechanism and the base more secure. This allows the seat to be more stably fixed to the base, improving the safety and reliability of the child safety seat. Simultaneously, when the first sliding rod slides to abut against the groove wall of the first sliding groove near the fixed rod, it alerts the user that the maximum angle has been adjusted, preventing the user from blindly adjusting.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] Child car seats are designed specifically for children of different ages, installed in cars, and effectively improve children's safety while traveling. In the event of a collision or sudden deceleration, they reduce the impact force on children and restrict their body movement, thus minimizing injury and ensuring their safety while traveling.

[0056] To provide a more comfortable riding environment for children, child safety seats are generally equipped with angle adjustment devices. However, traditional seat angle adjustment devices are prone to displacement and have poor reliability. This application provides an adjustment mechanism and a child safety seat to solve the aforementioned technical problems.

[0057] Firstly, please see Figures 1 to 3 This application provides an adjustment mechanism 100 for use in a child safety seat 200, connected between the seat 210 and the base 220 of the child safety seat 200, for adjusting the position of the seat 210 relative to the base 220.

[0058] Please see Figure 3The base 220 has a plurality of adjustment holes 221 spaced apart along a first direction a. The adjustment mechanism 100 can be mounted on the seat 210, and the adjustment mechanism 100 can be connected to different adjustment holes 221 on the base 220, so that when the adjustment mechanism 100 is connected to different adjustment holes 221, the relative position of the adjustment mechanism 100 and the base 220 changes, thereby changing the relative position of the seat 210 and the base 220. The first direction a can be a straight line or an arc, and this embodiment does not limit this. When the first direction a is a straight line, the adjustment mechanism 100 can adjust the position of the seat 210 relative to the base 220 along the straight line, for example, adjusting the seat 210 to move forward and backward, or to move up and down. When the first direction a is an arc, the adjustment mechanism 100 can adjust the position of the seat 210 relative to the base 220 along the arc, for example, adjusting the seat 210 to move forward and backward, to move up and down, or to adjust the angle.

[0059] Please see Figures 3 to 4 The adjustment mechanism 100 includes a base plate 110, a locking member 120, and an adjustment plate 130. The base plate 110 is used to install on the seat 210. The locking member 120 and the adjustment plate 130 are both installed on the seat 210 via the base plate 110. The seat 210 is installed on the base 220 via the locking member 120 and the adjustment plate 130 and is detachably connected to the base 220.

[0060] Please see Figures 4 to 6 The locking member 120 includes a locking part 121 and a driving part 122. The driving part 122 has a mounting hole c extending along a second direction b. One end of the locking part 121 is located in the mounting hole c. The second direction b is parallel to the axis of the adjusting hole 221 and is a straight line. The adjusting plate 130 is movably connected to the base plate 110 along a first direction a. The adjusting plate 130 is connected to the driving part 122 and is used to drive the locking member 120 to move along the second direction b when moving relative to the base plate 110 along the first direction a, so that the locking part 121 can be inserted into different adjusting holes 221.

[0061] The locking member 120 is designed to include a locking part 121 and a driving part 122. The extension direction of the mounting hole c of the driving part 122 is consistent with the extension direction of the hole axis of the adjustment hole 221, so that the position of the locking part 121 located in the mounting hole c can also be parallel to the hole axis of the adjustment hole 221. That is, the locking part 121 and the adjustment hole 221 are completely parallel. In this way, when the adjusting plate 130 drives the locking member 120 to move, the locking part 121 can be inserted into different adjustment holes 221 more smoothly. This avoids the locking part 121 from hitting the inner wall of the adjustment hole 221 when it is set at an angle to the adjustment hole 221. This improves the ease of operation of the adjustment mechanism 100, allowing users to adjust the angle of the child safety seat 200 more conveniently and effortlessly. 130 moves along the first direction a, and the locking member 120 moves along the second direction b. The first direction a and the second direction b are set at an angle. Therefore, the locking part 121 and the adjusting plate 130 are connected through the driving part 122. When the adjusting plate 130 moves, it first drives the driving part 122 to move, and then the driving part 122 drives the locking part 121 to move. There is a motion transmission process. Compared with the adjusting plate 130 directly driving the locking part 121 to move, it avoids the direct pulling of the locking part 121, which is prone to damage. At the same time, the locking part 121 passes through the mounting hole c of the driving part 122, and the contact area with the driving part 122 is larger, which strengthens the stability of the locking part 121 and makes it less likely to shake when the locking part 121 is inserted into the adjusting hole 221, which greatly improves the reliability of the adjusting mechanism 100.

[0062] Wherein, when the first direction a is an arc direction, the angle between the first direction a and the second direction b can be such that the plane containing the second direction b intersects with the plane containing the first direction a.

[0063] Further, please see Figures 5 to 7 The driving unit 122 includes a driving section 1221 and a mounting section 1222. The mounting section 1222 has a mounting hole c. The driving section 1221 is connected to the adjusting plate 130. The locking unit 121 includes a first locking section 1211, a mating section 1212, and a second locking section 1213. The mating section 1212 is located inside the mounting hole c. The first locking section 1211 is connected to the end of the mating section 1212 near the driving section 1221 and abuts against the surface of the mounting section 1222 near the driving section 1221. The second locking section 1213 is connected to the end of the mating section 1212 away from the driving section 1221, and is used to be inserted into different adjusting holes 221 under the drive of the adjusting plate 130. By abutting the first locking section 1211 against the surface of the mounting section 1222 near the driving section 1221, the connection between the locking unit 121 and the driving unit 122 is made more secure, so that the locking unit 121 is not easy to fall off, thus improving the reliability of the adjusting mechanism 100.

[0064] Furthermore, please see Figures 5 to 7 The mounting section 1222 includes a mounting body 1222a and a resilient claw 1222b. The mounting body 1222a is connected to the drive section 1221 and is provided with a mounting hole c. The elastic claw 1222b is located on the side of the mounting body 1222a near the drive section 1221, with one end connected to the mounting body 1222a and the other end extending in the direction away from the mounting body 1222a and close to the axis of the mounting hole c, so that the other end of the elastic claw 1222b is in a contracted state. The first locking section 1211 first passes through the mounting hole c, and then the contracted end of the elastic claw 1222b is squeezed to deform so that the first locking section 1211 can pass through. When the first locking section 1211 is completely inserted outside the elastic claw 1222b, the elastic claw 1222b returns to the contracted state to clamp the mating section 1212. At the same time, the surface of the elastic claw 1222b near the drive section 1221 abuts against the first locking section 1211 to fix the locking part 121 to the drive part 122. This design ensures the reliability of the connection between the locking part 121 and the drive part 122, and facilitates the assembly of the locking part 121 and the drive part 122.

[0065] To ensure the first locking segment 1211 is more securely inserted into the adjustment hole 221, please refer to... Figures 5 to 7 The diameter of the first locking segment 1211 can be larger than that of the mating segment 1212. One end of the mating segment 1212 connecting to the second locking segment 1213 can contract towards the axis of the mounting hole c to form a necked position, allowing the necked position of the mating segment 1212 to fit against the inner surface of the elastic claw 1222b, and the contracted end of the elastic claw 1222b can contract even further, thus more firmly clamping the locking part 121. Preferably, the length of the mating segment 1212 is greater than or equal to 16 mm and less than or equal to 20 mm, so that the first locking segment 1211 can completely pass through the adjustment hole 221, preventing it from easily falling off and improving the reliability of the adjustment mechanism 100. The locking part 121 and the driving part 122 can be made of at least one of plastic or metal. Plastic is inexpensive and easy to process. Metal has a high strength coefficient. Preferably, the locking part 121 can be made of metal, and the driving part 122 can be made of plastic, ensuring the structural strength of the locking member 120 while reducing manufacturing costs.

[0066] Understandably, please see Figures 8 to 9 The adjusting plate 130 has a first guide groove 131 whose extension direction is at an angle to both the first direction a and the second direction b. The extension direction of the first guide groove 131 is a straight line. When the first direction a is an arc, the intersection of the extension direction of the first guide groove 131 with the first direction a can be the intersection of the extension direction of the first guide groove 131 with the plane containing the first direction a.

[0067] The drive unit 122 is provided with a guide post 1223 located in the first guide groove 131, so that when the adjustment plate 130 moves relative to the bottom plate 110 in the first direction a, the guide post 1223 moves in the second direction b under the guidance of the first guide groove 131, so that the locking member 120 can be inserted into different adjustment holes 221.

[0068] For details, please see Figure 3 and Figure 5 When the adjusting mechanism 100 is in the locked state, the guide post 1223 is located in the first guide groove 131 of the adjusting plate 130 near the adjusting hole 221, and one end of the locking member 120 is located in an adjusting hole 221; please refer to Figure 3 and Figure 9 When the adjusting mechanism 100 is released from the locking state, the guide post 1223 is located in the first guide groove 131 of the adjusting plate 130 on the side away from the adjusting hole 221, and one end of the locking member 120 moves out of the adjusting hole 221.

[0069] More specifically, when the adjusting plate 130 moves in the positive direction of the first direction a, the guide post 1223, guided by the first guide groove 131, can move away from the adjusting hole 221. Simultaneously, the driving unit 122 drives the locking member 120 to move away from the adjusting hole 221, causing the locking member 120 to move out of the adjusting hole 221. At this time, the seat 210 can be slid to adjust the angle of the seat 210 relative to the base 220. After adjusting to the desired angle, the adjusting plate 130 moves in the negative direction of the first direction a until the guide post 1223 returns to the side of the first guide groove 131 closest to the adjusting hole 221, and one end of the locking member 120 is located in the adjusting hole 221 corresponding to the desired angle, thus completing the angle adjustment of the child safety seat 200. This design makes the overall structure of the adjusting mechanism 100 simple, its working principle simple and easy to operate, and facilitates subsequent inspection and maintenance.

[0070] Please see Figure 9 The base plate 110 is provided with a second guide groove 111 extending along the second direction b. The groove wall of the second guide groove 111 includes a first wall 1111 and a second wall 1112 extending along the second direction b and facing away from each other. The driving part 122 abuts against the first wall 1111 and the second wall 1112. The inner wall of the second guide groove 111 also includes a third wall 1113 perpendicular to the second direction b and facing the driving part 122. Please refer to [link to relevant documentation]. Figure 3 and Figure 5When the locking part 121 is located inside the adjustment hole 221, the driving part 122 abuts against the third wall surface 1113. By providing a second guide groove 111 extending along the second direction b, the driving part 122 located in the guide groove can only move along the second direction b, that is, along the direction parallel to the hole axis of the adjustment hole 221. At the same time, the locking part 121 connected to the driving part 122 can also only move along the second direction b, thus preventing the driving part 122 from deviating from the second direction b and causing the locking part 121 to be unable to smoothly insert into or remove from the adjustment hole 221, thereby enhancing the operational reliability of the adjustment mechanism 100.

[0071] Understandably, please see Figure 9 The adjusting plate 130 is provided with a third guide groove 132 extending along the first direction a, and the base plate 110 is provided with a mounting post 112 located within the third guide groove 132. The inner wall surface of the third guide groove 132 includes a fourth wall surface 1321 and a fifth wall surface 1322 distributed opposite to each other along the first direction a. The adjusting mechanism 100 also includes an elastic member 140 extending along the first direction a, one end of which is connected to the mounting post 112 on the base plate 110, and the other end is connected to the adjusting plate 130.

[0072] The specific working principle of the adjusting mechanism 100 is as follows: First, please refer to... Figure 4 The adjusting plate 130 moves in the positive direction of the first direction a (e.g., from the fifth wall surface 1322 to the fourth wall surface 1321), and the third guide groove 132 switches from the fourth wall surface 1321 abutting against the mounting post 112 to (see [reference]). Figure 9 The fifth wall surface 1322 abuts against the mounting post 112, and the elastic element 140 switches from the restoring state to the tensile state (see [link]). Figure 8 The locking member 120 moves out of the adjustment hole 221 along the first direction a, releasing the connection between the adjustment mechanism 100 and the base 220. Then, the adjustment plate 130 continues to move in the positive direction of the first direction a, and the mounting post 112, driven by the fifth wall surface 1322, causes the base 220 to follow the adjustment plate 130 in the positive direction of the first direction a until the chair seat 210 moves to the appropriate position with the adjustment mechanism 100. Finally, the adjustment plate 130 is released, and the elastic member 140, under its own elastic restoring force, drives the adjustment plate 130 to move relative to the base plate 110 in the opposite direction of the first direction a. At the same time, during the process of the adjustment plate 130 moving relative to the base plate 110 in the opposite direction of the first direction a, the adjustment plate 130 will drive the locking member 120 to move along the second direction b to insert into another adjustment hole 221 of the base 220. At this time, the mounting post 112 returns to the fourth wall surface 1321 that abuts against the third guide groove 132, completing one adjustment process.

[0073] Further, please see Figure 8 and Figure 10The adjusting plate 130 is provided with a hook 133. The elastic element 140 includes a spring 141 and a connecting ring 142. The spring 141 extends along the first direction a and one end is connected to the mounting post 112 on the base plate 110. The connecting ring 142 is connected to the end of the spring 141 away from the mounting post 112 and is hung on the hook 133. This arrangement allows the connecting ring 142 to be directly hung on the hook 133 of the adjusting plate 130, making the assembly of the elastic element 140 and the adjusting plate 130 simpler and more convenient. It also facilitates the disassembly and replacement of the elastic element 140 if it is damaged.

[0074] Secondly, please see Figures 1 to 3 This application provides a child safety seat 200, including the adjustment mechanism 100, base 220, and seat 210 as described above. The child safety seat 200 of this application embodiment improves the reliability of the adjustment mechanism 100 by designing the locking member 120 of the adjustment mechanism 100 to include a locking part 121 and a driving part 122, thereby enhancing the adjustment stability of the child safety seat 200 and allowing users to adjust the angle of the child safety seat 200 more conveniently and effortlessly.

[0075] Understandably, please see Figure 11 The base 220 includes a base body 222 and a mounting bracket 223. The mounting bracket 223 is connected to the base body 222 and has multiple adjustment holes 221. The base 220 is designed to include the base body 222 and the mounting bracket 223. The chair seat 210 is mounted on the base 220 via an adjustment mechanism 100 and the mounting bracket 223, allowing the base 220 and chair seat 210 to be completely separated. This allows the chair seat 210 to be mounted on the base 220 in either a forward or reverse orientation, providing users with more usage options. Preferably, there are two mounting brackets 223, symmetrically connected to the base body 222 at intervals along the second direction b. The adjustment plate 130 has two first guide grooves 131 symmetrically arranged along the second direction b, and two locking members 120, each passing through one of the two first guide grooves 131. The two locking parts 121 are respectively inserted into the adjustment holes 221 of the two mounting brackets 223. Preferably, please refer to... Figure 12 One end of the adjustment plate 130 extends out of the base plate 110 and is located at the bottom of the seat 210, making it easy for the user to pull and adjust.

[0076] Further, please see Figure 3 and Figure 11The mounting bracket 223 has a first sliding groove d extending along a first direction a. The adjusting mechanism 100 further includes a side plate 150, a first sliding rod 160, and a fixing rod 170. The side plate 150 is connected to the base plate 110 and is disposed opposite to the mounting bracket 223. The side plate 150 has a second sliding groove 151 extending along the first direction a. The first sliding rod 160 extends along a second direction b, with one end connected to the side plate 150 and the other end passing through the first sliding groove d. The fixing rod 170 extends along the second direction b, connects to the mounting bracket 223, and passes through the second sliding groove 151. By setting a first sliding rod 160 and a fixed rod 170, one end of the first sliding rod 160 is connected to the side plate 150, and the other end passes through the first sliding groove d of the mounting bracket 223. The fixed rod 170 is connected to the mounting bracket 223 and passes through the second sliding groove 151 of the side plate 150, making the connection between the adjustment mechanism 100 and the base 220 more secure. This allows the seat to be more firmly fixed to the base 220, improving the safety and reliability of the child safety seat 200. At the same time, when the first sliding rod 160 slides to abut against the groove wall of the first sliding groove d near the fixed rod 170, it reminds the user that it has been adjusted to the maximum angle, making it more practical and thoughtful.

[0077] Understandably, please see Figure 13 The child safety seat 200 may also include a seat belt holder 230, which is attached to the side of the seat 210 for clamping the vehicle's seat belt, so that the child safety seat 200 can be more securely fixed in the vehicle.

[0078] Further, please see Figure 14 The seatbelt holder 230 includes a base 231 and a clamping arm 232. The base 231 is connected to the side of the seat 210, and the clamping arm 232 is rotatably connected to the base 231. Further details can be found in the following section. Figure 15 The base 231 includes a base plate and peripheral side plates connecting the base plate. The base plate 110 is connected to the side of the seat 210. The peripheral side plates have multiple spaced anti-slip protrusions 2311. By providing anti-slip protrusions 2311, the clamping and anti-slip effects of the seat belt holder 230 can be improved, further enhancing the stability of the child safety seat 200. Preferably, the number of anti-slip protrusions 2311 is four or more, and the height of the anti-slip protrusions 2311 extending toward the clamping arm 232 is greater than or equal to 3 mm and less than or equal to 4 mm.
