[0064] The realization, functional features and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0065] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0066] Referring to Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 11 , in some embodiments, the seat assembly includes a seat body 100 and a seat belt gripper 200. The seat body 100 includes a locking assembly 110. The seat belt gripper 200 includes a clamping block 210 and a locking rod 220 connected to the clamping block 210. The clamping block 210 is rotatably connected to the seat body 100 to realize the pressing and releasing of the seat belt. A locking groove 211 is provided on one side of the clamping block 210 facing the locking assembly 110. At least a part of the locking rod 220 is located in the locking groove 211. The seat belt gripper 200 is configured to be able to rotate to enable the locking assembly 110 to extend into the locking groove 211 and engage with the locking rod 220. The engagement between the locking assembly 110 and the locking rod 220 can keep the seat belt gripper 200 in the state of pressing the seat belt.

[0067] Among them, one side of the clamping block 210 along the direction parallel to its rotation axis is provided with an installation hole 212. The installation hole 212 communicates with the locking groove 211. The installation hole 212 is for the locking rod 220 to pass through, so that the locking rod 220 is installed in the locking groove 211. The locking rod 220 is inserted into the installation hole 212 along the direction parallel to the rotation axis of the clamping block 210 and then installed into the locking groove 211. With such a design, the components in the locking groove 211 only need to maintain a suitable structure to accommodate the locking rod 220, and there is no need to set up movable joints to cooperate with the dynamic process of the locking groove 211 from installation to maintaining fixation. Therefore, the present application can select rigid materials or rigid joints, and only needs to have the ability to accommodate the locking rod 220, without considering the installation of the locking rod 220. Therefore, the mechanical structure of the seat assembly of the present application has better stability and higher strength, and thus the seat assembly of the present application has better safety.

[0068] It can be understood that in some embodiments, the shape and size of the locking rod 220 can be adjusted according to actual needs. For example, the locking rod 220 can be designed in an L shape or a T shape to better adapt to the shape of the locking groove 211. In addition, the size of the locking groove 211 can also be adjusted according to the size of the locking rod 220 to ensure the matching degree between the two, thereby improving the locking effect. Through such a design, the seat assembly can better meet the needs of different usage scenarios and improve the user experience.

[0069] It can be understood that in some embodiments, in order to ensure that the locking rod 220 can be smoothly inserted into the locking groove 211 and prevent the locking rod 220 from coming out due to external impact during use, the shape of the locking groove 211 is designed as a long groove matching the locking rod 220. The diameter of the locking rod 220 is slightly smaller than the width of the locking groove 211, so that the locking rod 220 can slide freely in the locking groove 211 but will not easily come off. The depth of the locking groove 211 is also designed to ensure that the locking rod 220 can still be firmly stuck in the locking groove 211 when subjected to external forces. Due to the tight fit between the locking groove 211 and the locking rod 220, when the seat assembly bears a load, relative sliding between the locking rod 220 and the locking groove 211 is not likely to occur, thus ensuring the stability and safety of the seat assembly.

[0070] It should be noted that in some embodiments, with reference to Figure 1 and Figure 2, the seat assembly of the present application further includes a base 411, a seat, a backrest 413, a forward perforation 414, a rearward perforation 415, a headrest portion 416, a wing portion 417, a side impact protection block 418, a side buffer body 419, and a leg rest plate 420. The seat belt clip 200 includes a forward clip group 421 and a rearward clip group 422. Specifically, the base 411 is the basic part of the entire child safety seat, and it is usually fixed to the car seat by an ISOFIX interface or the vehicle's seat belt. The design of the base 411 needs to ensure that the seat is firmly installed in the car and can withstand the impact force generated during a collision. The seat directly contacts the child's body and provides basic support. It is connected to the base 411 and can be adjusted in angle to adapt to different usage modes (forward or rearward). The backrest 413 is part of the seat and is designed to support the child's back. In the forward usage mode, the forward clip group 421 on the backrest 413 will be used to fix the seat belt. The forward clip group 421 is provided on the backrest 413. When the seat is in the forward usage mode, this clip group is used to correctly fix the child's seat belt to ensure that the child can be properly protected in the event of a collision. The rearward clip group 422 is provided on the seat portion. When the seat is in the rearward usage mode, this clip group is used to fix the seat belt. The rearward usage mode is usually suitable for younger children because it can better protect their heads and necks. The forward perforation 414 and the rearward perforation 415 are used for the vehicle seat belt to pass through so as to fix the seat to the car seat. The forward perforation 414 is usually located on the backrest 413, and the rearward perforation 415 is located on the seat portion or the backrest 413, depending on the design of the seat. The headrest portion 416 is slidably connected to the backrest 413 of the seat and can be adjusted according to the child's height to ensure the best protection for the child's head in the event of a collision. The wing portion 417 is an extension of both sides of the seat, and they are designed to protect the sides of the child, especially in the case of a side collision. The side impact protection block 418 is fixed to the outer wall of the wing portion 417 and is intended to enhance the protection of the child by the seat during a side collision. The side buffer body 419 is located on both sides of the seat and is intended to absorb the impact force during a side collision and reduce the force transmitted to the child. The leg rest plate 420 is part of the seat and is located in front of the child's legs and can provide additional comfort and support, especially during a long journey.

[0071] Refer to Figure 12, in some embodiments, the seat assembly further includes a plug 230 detachably disposed in the mounting hole 212 for preventing the locking rod 220 from disengaging from the locking groove 211. Specifically, after the locking rod 220 extends into the locking groove 211, the plug 230 is installed in the mounting hole 212 to prevent the locking rod 220 from disengaging from the locking groove 211 due to external forces, ensuring the stability of the seat assembly. The user can install or remove the plug 230 manually or with the assistance of tools, facilitating maintenance and replacement. The design of the plug 230 enhances the safety performance of the seat assembly, such that even during severe shaking during use, the locking rod 220 is not easily disengaged, ensuring the safety of the seat.

[0072] It can be understood that, in some embodiments, the plug 230 can be made of various materials, such as plastic, metal, or rubber, etc., to adapt to different usage environments. The design of the plug 230 can consider the characteristics of easy installation and disassembly, such as using screw fixation or snap-fit design, further enhancing the user experience. Additionally, the plug 230 can also have certain elastic properties, allowing the locking rod 220 to deform slightly during installation, making it easier to insert into the locking groove 211, while also ensuring that the locking rod 220 will not easily disengage under normal usage conditions. Such a design not only enhances the functionality of the seat assembly but also improves user satisfaction.

[0073] Furthermore, in some embodiments, the plug 230 is designed as a plug made of an elastic material that enters the mounting hole 212 through extrusion deformation, thereby tightly closing the opening of the mounting hole 212. The elastic material of the plug 230 makes it easy to deform during installation, facilitating insertion into the mounting hole 212. After installation, the plug 230 returns to its original state and tightly clamps the edge of the mounting hole 212, effectively preventing the locking rod 220 from falling off.

[0074] Refer to Figure 11 and Figure 14 , in some embodiments, a plugging groove 240 is provided on the side of the clamping block 210 facing the locking assembly 110. The plugging groove 240 communicates with the mounting hole 212, and the plug 230 extends into or out of the mounting hole 212 from the plugging groove 240. Specifically, the plugging groove 240 is a groove specifically provided on the clamping block 210 for accommodating the plug 230. The plug 230 extends into the plugging groove 240 along a direction perpendicular to the axis of the locking rod 220, plugging the mounting hole 212 from the outside to prevent the locking rod 220 from disengaging from the locking groove 211 due to external forces. With such a design, the plug 230 will be completely hidden in the plugging groove 240, being aesthetically pleasing and neat. Moreover, the plugging groove 240 can be arbitrarily set on the clamping block 210, i.e., the distance to the end of the locking rod 220 can be adjusted at will to better fit the length of the locking rod 220, thereby further ensuring the plugging effect on the locking rod 220.

[0075] Of course, it can be understood that in some embodiments, the plugging member 230 can be designed in various forms, such as a shrapnel, a spring buckle, or a threaded locking member, etc. These designs not only ensure that the locking rod 220 will not accidentally fall off, but also facilitate the user to select a suitable type of plugging member 230 according to the actual situation to meet the requirements of different usage scenarios. The tight fit between the plugging member 230 and the clamping block 210 effectively prevents the locking rod 220 from loosening when subjected to impact or vibration, thus ensuring the overall stability of the seat assembly and improving the user experience.

[0076] Referring to Figure 6 、 Figure 8 and Figure 12 , in some embodiments, the seat belt clip 200 of the seat assembly further includes a cover plate 250. The cover plate 250 is detachably connected to the side of the clamping block 210 facing the locking assembly 110. An avoidance groove 251 communicating with the locking groove 211 is provided on the cover plate 250. The plugging member 230 is connected to the side of the cover plate 250 facing the clamping block 210. In this way, the cover plate 250 can not only play a protective role, but also facilitate maintenance personnel to check and adjust the position of the locking rod 220. The design of the avoidance groove 251 enables the movement of the locking rod 220 in the locking groove 211 to be unobstructed. At the same time, the plugging member 230 can be directly arranged on the cover plate 250 and fall into the plugging groove 240 of the clamping block 210 as the cover plate 250 is closed, so as to achieve the plugging effect on the mounting hole 212.

[0077] It can be understood that the plugging member 230 can be integrally provided with the cover plate 250, or the plugging member 230 can be separately provided from the cover plate 250. Regarding the case where the plugging member 230 and the cover plate 250 are separately provided, the plugging groove 240 can be used in advance to accommodate the plugging member 230 to prevent the loss of the plugging member 230.

[0078] It can be understood that the specific material of the cover plate 250 depends on the actual requirements. In some embodiments, the cover plate 250 can be made of plastic material, specifically pp material, and the cover plate 250 and the plugging member 230 are integrally injection-molded. When the plugging member 230 and the cover plate 250 are integrally formed, the plugging member 230 can withstand greater thrust, so that the blocking effect of the plugging member 230 on the locking rod 220 is better, and the functional role of the locking rod 220 can be ensured; in other embodiments, the cover plate 250 can also be made of metal sheet. The cover plate 250 and the clamping block 210 are provided with corresponding mating holes and are fixed to the clamping block 210 by screws. The shape of the avoidance groove 251 on the cover plate 250 is customized according to the size of the locking groove 211 to ensure sufficient space while not affecting the normal operation of the locking rod 220. Due to the presence of the cover plate 250, the overall appearance of the seat assembly is more tidy, and at the same time, it is convenient for later maintenance work. When the seat assembly is in the working state, the cover plate 250 and the plugging member 230 work together to ensure that the locking rod 220 is firmly fixed in the locking groove 211, further enhancing the stability and safety of the seat assembly.

[0079] It can be understood that in some embodiments, the connection method between the cover plate 250 and the clamping block 210 can be diversified, such as using snap-fasteners, magnetic attraction or quick-release mechanisms, etc., which are not only convenient for disassembly and assembly but also ensure the firmness of the connection. In this way, users can easily adjust the position of the locking rod 220 without damaging the structure of the seat assembly, making the seat assembly more flexible and adaptable to more usage occasions.

[0080] Refer to Figure 7 , in some embodiments, a first limiting rib 260 is provided in the locking groove 211 of the seat assembly. The first limiting rib 260 contacts the locking rod 220, and its two ends are respectively connected to the two side walls of the locking groove 211 along the direction perpendicular to the rotation axis. The design of the first limiting rib 260 fixes the position of the locking rod 220 in the locking groove 211, preventing the locking rod 220 from moving in the direction perpendicular to the rotation axis, thus ensuring the stability of the locking rod 220 in the locked state. The setting of the first limiting rib 260 restricts the random shaking movement of the locking rod 220 in the locking groove 211, and it can only move along the direction of the rotation axis, which improves the safety performance of the seat assembly. In addition, the first limiting rib 260 can be arc-shaped, and the locking rod 220 is trapped in the arc-shaped structure. The two ends of the first limiting rib 260 are connected to the two side walls of the locking groove 211, further strengthening the positioning of the locking rod 220 in the locking groove 211, making the locking rod 220 not easily deviate from the predetermined position, thus ensuring the mechanical structure stability of the seat assembly.

[0081] In some embodiments, a second limiting rib 270 may also be provided in the locking groove 211. The second limiting rib 270 also contacts the locking rod 220, but one end thereof is connected to a side wall of the locking groove 211, and the other end is arranged in a suspended manner. Such a design makes the second limiting rib 270 have a certain elasticity. It can be understood that if the recess of the arc-shaped structure of the first limiting rib 260 and the second limiting rib 270 are respectively arranged on opposite sides of the locking member along the length direction, the first limiting rib 260 can provide an elastic force to press the locking rod 220, so that the locking rod 220 fits more firmly against the arc-shaped structure of the second limiting rib 270. This arrangement of the second limiting rib 270 further restricts the position of the locking rod 220 in the locking groove 211.

[0082] In addition, the suspended end of the second limiting rib 270 can play a buffering role. When the locking rod 220 moves in this direction due to an external force, the suspended end of the second limiting rib 270 can absorb part of the energy and reduce the direct impact of the locking rod 220 on the wall of the locking groove 211. Through the combined action of the first limiting rib 260 and the second limiting rib 270, not only the position of the locking rod 220 in the locking groove 211 is limited, but also the impact resistance of the locking rod 220 is improved, thereby enhancing the safety and durability of the seat assembly.

[0083] Of course, it can be understood that glue can be added in the locking groove 211, and the thickness of the added glue is at least 2.8 mm to enhance the strength here, that is, the strength at the locking rod 220, so as to prevent the seat belt clip from cracking.

[0084] Referring to Figure 14 , in some embodiments, along the axial direction of the mounting hole 212, the length dimension of the locking rod 220 can be smaller than the length dimension of the locking groove 211, and the length dimension of the locking rod 220 is greater than the distance between the first limiting rib 260 and the second limiting rib 270, so that the first limiting rib 260 and the second limiting rib 270 can well support the locking rod 220, and at the same time, it is also convenient for the assembly of the locking rod 220. In other embodiments, the length dimension of the locking rod 220 along the axial direction of the mounting hole 212 is greater than the length dimension of the locking groove 211, and at the same time, a part of the locking rod 220 is located in the mounting hole 212. Specifically, the length dimension of the locking rod 220 being greater than the length dimension of the locking groove 211 makes the part of the locking rod 220 in the mounting hole 212 longer than the part in the locking groove 211, which helps the stable positioning of the locking rod 220 in the locking groove 211. The longer length dimension of the locking rod 220 in the mounting hole 212 enables the locking rod 220 to be firmly fixed in the mounting hole 212 and is not easily displaced or detached due to the action of external forces.

[0085] Furthermore, such a design allows the locking rod 220 to have a larger range of motion in the locking groove 211, which can adapt to different usage requirements. The length of the locking rod 220 in the locking groove 211 is greater than the length of the locking groove 211 itself, which means that the locking rod 220 can go deep into the locking groove 211, and even partially exceed the boundary of the locking groove 211, making the connection between the locking rod 220 and the locking assembly 110 more secure. The locking rod 220 is partially located in the mounting hole 212, which ensures the stability of the locking rod 220. Even when subjected to external force, the locking rod 220 is not easy to disengage from the locking groove 211, thereby improving the safety performance of the seat assembly.

[0086] It is understandable that the length of the locking rod 220 is designed to be longer than the locking slot 211, so that a portion of the locking rod 220 can extend out of the locking slot 211. This portion of the locking rod 220 is located in the mounting hole 212, which plays an additional supporting role. The longer the portion of the locking rod 220 in the mounting hole 212, the more stable the engagement between the locking rod 220 and the locking assembly 110, and the higher the safety of the seat assembly.

[0087] Reference Figure 6 In some embodiments, the locking assembly 110 in the seat assembly includes a first rotating shaft 111, a hook 112 and a driving part 113. The driving part 113 and the hook 112 are both connected to the first rotating shaft 111. The first rotating shaft 111 is rotatably connected to the cushion part 412 or the backrest part 413 of the seat body 100. The hook 112 is used to engage with the locking rod 220 to achieve the locking function. The safety belt clip 200 also includes an unlocking part 215, which is rotatably connected to the clamping block 210. The unlocking part 215 includes an unlocking end 2151 and a transmission end 2152. The unlocking end 2151 is located on the side of the clamping block 210 away from the locking assembly 110, and the transmission end 2152 is located on the side close to the locking assembly 110. When the unlocking end 2151 is driven, the transmission end 2152 will be driven to rotate relative to the clamping block 210. The rotation of the transmission end 2152 can drive the driving part 113 to rotate. The rotation of the driving part 113 can drive the hook 112 to rotate, thereby separating the hook 112 from the locking rod 220 and completing the unlocking action.

[0088] Specifically, when the user needs to unlock the seat assembly, the unlocking end 2151 is operated to rotate relative to the clamping block 210, and this action drives the transmission end 2152 to rotate, and the rotation of the transmission end 2152 drives the driving part 113 to rotate, and the rotation of the driving part 113 further drives the hook 112 to rotate, so that the hook 112 is separated from the locking rod 220. This structure realizes the rapid separation between the locking rod 220 and the hook 112 through a simple mechanical linkage, so that the seat assembly can be unlocked conveniently, and the user experience is improved.

[0089] Furthermore, a torsion spring 114 is arranged beside the buckle, and the torsion spring 114 is sleeved on the first rotating shaft 111. The driving part 113 and the hook 112 are both fixed to the first rotating shaft 111. The driving part 113 rotates to drive the first rotating shaft 111 to rotate, and the first rotating shaft 111 rotates to drive the hook 112 to rotate, and these movements are performed synchronously. The two ends of the torsion spring 114 extend outward, and one end extends to the hook 112, pressing on the hook 112 to provide the hook 112 with sufficient elastic force.

[0090] It is understood that, in some embodiments, the design of the unlocking portion 215 may consider adding components such as a handle or a button that are convenient for user operation to improve the comfort and convenience of unlocking. In addition, in order to ensure the engagement strength between the hook 112 and the locking rod 220, the shape and size of the hook 112 and the locking rod 220 may be optimized. For example, the hook 112 may be designed to have an inclined structure so that it can automatically align with the locking rod 220 during the engagement process, reducing the difficulty of user operation. Through such a design, the seat assembly improves the efficiency of unlocking and the satisfaction of users while ensuring safety.

[0091] Reference Figures 7 to 15 In some embodiments, the minimum thickness of the wall plate of the mounting hole 212 of the seat assembly is greater than or equal to 2.8 mm, for example, the minimum thickness of the wall plate of the mounting hole 212 of the seat assembly can be 2.8 mm, 3.0 mm, 3.2 mm, 3.4 mm, 3.6 mm, etc. The minimum thickness of the wall plate of the locking groove 211 is greater than or equal to 2.8 mm, for example, the minimum thickness of the wall plate of the locking groove 211 can be 2.8 mm, 3.0 mm, 3.2 mm, 3.4 mm, 3.6 mm, etc., to ensure the structural strength of the mounting hole 212 and the locking groove 211. The clamp block 210 is provided with a pivot hole 214 extending in a direction parallel to the rotation axis, and the safety belt clip 200 further includes a second rotating shaft 216 passing through the pivot hole 214, and both ends of the second rotating shaft 216 are connected to the seat body 100. The side of the clamp block 210 away from the seat body 100 is provided with a pivot groove 213 communicating with the pivot hole 214. The minimum thickness of the wall of the clamp block 210 defining the pivot slot 213 is greater than or equal to 2.8 mm. For example, the minimum thickness of the wall of the clamp block 210 defining the pivot slot 213 may be 2.8 mm, 3.0 mm, 3.2 mm, 3.4 mm, 3.6 mm, etc., to ensure the stability of the safety belt clip 200 during the rotation process. Figure 16 The seat assembly also includes a reinforcing tube 300 connected to the seat body 100. The reinforcing tube 300 is provided with a pin hole 310 connected to the seat body 100. The diameter of the pin hole 310 is between 8.8 mm and 9.2 mm. For example, the diameter of the pin hole 310 can be 8.8 mm, 9.0 mm, 9.2 mm, etc. to ensure the connection strength.

[0092] Specifically, the design of the clamp block 210 allows the safety belt clip 200 to rotate around the pivot hole 214, and the second shaft 216 ensures a stable connection between the safety belt clip 200 and the seat body 100. The thickness of the wall plate of the clamp block 210 defining the pivot slot 213 is greater than or equal to 2.8 mm, ensuring that the clamp block 210 will not be deformed or damaged when subjected to a large stress, thereby improving the structural strength of the seat assembly. The size of the pin hole 310 of the reinforcing tube 300 is designed to be between 8.8 mm and 9.2 mm, so that the seat assembly can be connected to other components through a pin, thereby enhancing the versatility and flexibility of the seat assembly.

[0093] It is understood that in some embodiments, in order to further enhance the stability of the seat assembly, the material of the clamp block 210 can be selected from high-strength alloys or composite materials to ensure that it can maintain good performance under long-term use. At the same time, the design of the reinforcement tube 300 can consider adding an anti-slip coating or surface texture treatment to increase friction and prevent the seat assembly from sliding during use. Through the above measures, the seat assembly is not only more structurally solid, but also has a better user experience and safety.

[0094] Reference Figures 1 to 6 In some embodiments, the seat assembly includes a seat body 100, and the seat body 100 includes a cushion portion 412 and a backrest portion 413 connected to the cushion portion 412. The locking assembly 110 can be connected to the cushion portion 412, and the clamping block 210 is rotatably connected to the cushion portion 412; or the locking assembly 110 is connected to the backrest portion 413, and the clamping block 210 is rotatably connected to the backrest portion 413. The seat assembly can also include two locking assemblies 110 and two safety belt clips 200, one of which is connected to the cushion portion 412 and the other is connected to the backrest portion 413. The safety belt clip 200 is configured to be rotatable so that the locking assembly 110 extends into the locking groove 211 and engages with the locking rod 220. Such a design makes the locking mechanism of the seat assembly more flexible, and different installation positions of the locking assembly 110 and the safety belt clip 200 can be selected according to actual needs, so that the seat assembly can be used in various situations.

[0095] Specifically, when the locking component 110 is connected to the seat cushion part 412, the seat belt clip 200 is rotatably connected to the seat cushion part 412 through the clamping block 210, so that the seat belt clip 200 can rotate around the rotation axis. When the locking rod 220 enters the locking groove 211 and engages with the locking component 110, the seat belt clip 200 is fixed. When the locking component 110 is connected to the backrest part 413, the seat belt clip 200 is rotatably connected to the backrest part 413 through the clamping block 210, also enabling the seat belt clip 200 to rotate around the rotation axis and be fixed. In the case where the seat assembly includes two locking components 110 and two seat belt clips 200, the two locking components 110 are respectively connected to the seat cushion part 412 and the backrest part 413, and the two seat belt clips 200 are respectively rotatably connected to the seat cushion part 412 and the backrest part 413 and cooperate with the corresponding locking components 110 for clamping connection to ensure that the seat assembly can achieve the locking function in different positions. Such a design enables the seat assembly to provide a stable locking effect in multiple directions, enhancing the practicality and safety of the seat assembly.

[0096] It can be understood that the seat assembly may include only one seat belt clip 200, or may include two or more seat belt clips 200 at the same time, or multiple seat belt clips 200 with the same structure can be arranged at different positions. The specific design depends on the actual use situation to ensure the stability of the seat belt under a reasonable layout.

[0097] It can be understood that in some embodiments, the cooperation between the locking component 110 and the seat belt clip 200 can be further optimized. For example, the hook 112 in the locking component 110 can be designed to be elastic to facilitate the locking rod 220 to more easily enter the locking groove 211; and the friction coefficient of the clamping block 210 in the seat belt clip 200 can be increased to prevent sliding in the locked state. In addition, the connection method between the locking component 110 and the seat body 100 can adopt various methods such as welding, riveting or bolt connection, etc., to ensure the firmness and reliability of the connection. Through these improvements, the seat assembly is more stable during use and the user operation is more convenient.

[0098] Of course, it can be understood that in some embodiments, the installation positions of the locking component 110 and the seat belt clip 200 can be adjusted according to the specific design of the seat. For example, the locking component 110 can be designed to be hidden inside the seat, and the locking and unlocking are achieved through the rotation of the seat belt clip 200.

[0099] Refer to Figures 1 to 16, an embodiment of the second aspect of the present application provides a child seat, which includes the seat assembly of any of the foregoing embodiments. The child seat further includes a headrest assembly and a base 411. The headrest assembly is movably connected to the upper end of the backrest 413 of the seat assembly, and the base 411 is movably connected to the seat cushion portion 412 of the seat assembly. Such a design enables the child seat to not only have the basic functions of a seat, but also adjust the height of the headrest according to the height of the child and adjust the tilt angle of the seat as needed. Through the locking mechanism in the seat assembly, the safety of the child on the seat can be ensured.

[0100] Further, the seat assembly of the child seat in this embodiment has higher stability and structural strength, and the principle has been described above and will not be elaborated here. Therefore, the child assembly of the present application has higher structural strength and better safety.
