Detailed Implementation

[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0032] This application proposes a car child seat 100 that allows for height adjustment of the headrest assembly 20 relative to the backrest assembly 10 to meet user needs.

[0033] Referring to Figures 1 to 8, a car child seat 100 according to an embodiment of this application includes a backrest assembly 10, a headrest assembly 20, a locking member 30, and a positioning member 40.

[0034] The back assembly 10 is provided with a plurality of positioning grooves 11 distributed in the vertical direction. The head assembly 20 is connected to the back assembly 10 and is movable in the vertical direction. The locking member 30 is connected to the head assembly 20 and includes a locking part 31 that is detachably disposed in the positioning groove 11. The positioning member 40 selectively abuts against the locking part 31 to prevent the locking part 31 from disengaging from the positioning groove 11. With this configuration, the height of the head assembly 20 relative to the back assembly 10 can be adjusted by the locking member 30 and the positioning member 40 to meet user needs.

[0035] Specifically, the head assembly 20 can move vertically relative to the back assembly 10. By locking and unlocking with the cooperation of the locking member 30 and the positioning member 40, the height of the head assembly 20 on the back assembly 10 can be adjusted. When the head assembly 20 is locked, the locking member 30 can be disposed in at least one of the multiple positioning slots 11, and the positioning member 40 selectively abuts to prevent the locking part 31 from disengaging from the selected positioning slot 11, thereby locking the head assembly 20 on the back assembly 10. When the head assembly 20 is unlocked, the positioning member 40 can release the abutment on the locking part 31. At this time, the locking member 30 can disengage from the positioning slot 11, which facilitates the vertical movement of the head assembly 20 relative to the back assembly 10, thereby realizing the height adjustment of the head assembly 20 relative to the back assembly 10.

[0036] In addition, depending on the actual situation, the locking member 30 can actively disengage from the positioning groove 11 by means of user drive or other means; it can also be passively disengaged from the positioning groove 11 by mutual pressure with the positioning groove 11. Both of the above can realize the disengagement of the locking member 30 in the positioning groove 11, which facilitates the height adjustment of the car child seat 100.

[0037] In addition, the car child seat 100 in this embodiment has a simple and reliable structure, which can improve the user's safety.

[0038] As described above, referring to Figures 1 to 5, in some embodiments of this application, the locking member 30 further includes a main body 32 and an elastic part 33. The main body 32 is disposed on the head assembly 20, the elastic part 33 is connected to the main body 32 and can be elastically deformed, and the locking part 31 is disposed on the elastic part 33. This arrangement can improve the height adjustment efficiency of the car child seat 100.

[0039] In detail, the backrest assembly 10 is provided with a plurality of positioning protrusions 12 distributed in the vertical direction, and the aforementioned positioning grooves 11 are formed between two adjacent positioning protrusions 12. When the headrest assembly 20 is unlocked, the positioning member 40 can release the stop on the locking part 31, and the elastic part 33 can still be located in the positioning groove 11. At this time, the headrest assembly 20 can be driven to move in the vertical direction relative to the backrest assembly 10. The positioning protrusions 12 can press against the elastic part 33 to make the elastic part 33 elastically deform, so that the locking part 31 passes over the positioning protrusions 12, that is, from one positioning groove 11 to another positioning groove 11, realizing the height adjustment of the car child seat 100. The structure is simple and the adjustment efficiency is high. When the headrest assembly 20 is locked, the locking part 31 can be provided in one of the plurality of positioning grooves 11, and the positioning member 40 selectively stops the locking part 31, so that the locking part 31 is restricted in the selected positioning groove 11, thereby locking the headrest assembly 20 on the backrest assembly 10, realizing the height adjustment of the car child seat 100.

[0040] Referring to Figures 1, 2, 6, and 7, in some embodiments of this application, the positioning groove 11 is configured as a flared structure. It can be understood that the positioning groove 11 gradually widens in the direction from the bottom of the groove to the opening of the groove. In this way, the side wall of the positioning groove 11 can form a guiding structure. When the height of the car child seat 100 is adjusted, the side wall of the positioning groove 11 can guide the locking part 31 to pass over and disengage, thereby improving the smoothness of the height adjustment of the car child seat 100.

[0041] In some specific examples, the positioning groove 11 includes an upper side wall 111 and a lower side wall 112. The upper side wall 111 and the lower side wall 112 are arranged in a top-to-bottom direction. The upper side wall 111 and the lower side wall 112 gradually expand from the bottom of the positioning groove 11 to the opening of the groove. That is, the upper side wall 111 is inclined away from the locking part 31 in a top-to-bottom direction, and the lower side wall 112 is inclined towards the locking part 31 in a top-to-bottom direction, so as to form guide structures for guiding the locking part 31 out of the positioning groove 11. When the locking part 31 comes out of the positioning groove 11 upward, the upper side wall 111 of the positioning groove 11 can guide the locking part 31 out. When the locking part 31 comes out of the positioning groove 11 downward, the lower side wall 112 of the positioning groove 11 can guide the locking part 31 out.

[0042] Referring to Figures 1 to 5, in some other embodiments of this application, the upper and lower sides of the locking part 31 gradually converge in the direction from the fixed end to the free end. In this way, the upper and lower sides of the locking part 31 can form a guide structure. When the height of the car child seat 100 is adjusted, the upper and lower sides of the locking part 31 can guide itself to pass over and disengage from the positioning groove 11, thereby improving the smoothness of the height adjustment of the car child seat 100.

[0043] In some specific examples, the upper side of the locking part 31 is inclined towards the positioning groove 11 in a downward direction, and the lower side of the locking part 31 is inclined away from the positioning groove 11 in a downward direction, so as to form a guide structure for guiding the indicated disengagement from the positioning groove 11; when the locking part 31 disengages upward from the positioning groove 11, the upper side of the locking part 31 can guide the locking part 31 to disengage from the positioning groove 11; when the locking part 31 disengages downward from the positioning groove 11, the lower side of the locking part 31 can guide the locking part 31 to disengage from the positioning groove 11.

[0044] Referring to Figures 1 to 5, in some embodiments of this application, the positioning member 40 is movably disposed on the main body 32 and has a positioning position and a release position. When in the positioning position, the positioning member 40 abuts against the locking part 31, and when in the release position, the positioning member 40 moves away from the locking part 31. This arrangement enables height adjustment of the car child seat 100.

[0045] Specifically, the positioning member 40 is connected to and movable to the main body 32 to move closer to and further away from the locking part 31. When it is necessary to lock the head assembly 20, the positioning member 40 can move relative to the main body 32 and closer to the locking part 31 to move to the positioning position. At this time, the positioning member 40 can stop the locking part 31 to prevent the locking part 31 from disengaging from the positioning groove 11, thereby locking the head assembly 20 onto the back assembly 10. When it is necessary to unlock the head assembly 20, the positioning member 40 can move relative to the main body 32 and further away from the locking part 31 to move to the release position. At this time, the positioning member 40 is away from the locking part 31, and the locking part 31 can disengage from the positioning groove 11 to facilitate the height adjustment of the car child seat 100.

[0046] Referring to Figures 1 to 5, in some specific examples, the main body 32 extends in the vertical direction, and the lower part of the main body 32 is connected to the elastic part 33. The positioning member 40 is movably disposed on the main body 32 in the vertical direction. When the positioning member 40 moves downward to the positioning position, the side of the positioning member 40 can stop the locking part 31 to prevent the locking part 31 from dislodging from the positioning groove 11. When the positioning member 40 moves upward to the release position, the side of the positioning member 40 moves away from the locking part 31, thereby releasing the restriction on the locking part 31.

[0047] In some embodiments of this application, the car child seat 100 further includes an elastic element, which is connected to the locking element 30 and the positioning element 40 respectively, and has an elastic force that drives the positioning element 40 to move toward the locking part 31; this configuration can improve the height adjustment efficiency of the car child seat 100.

[0048] Specifically, in conjunction with the foregoing, the upper end of the elastic member can be connected to the main body 32, and the lower end of the elastic member can be connected to the positioning member 40. The elastic member has an elastic force that drives the positioning member 40 to move towards the locking part 31 connected to the lower end of the main body 32. When unlocking the head assembly 20, the user can overcome the elastic force of the elastic member to drive the positioning member 40 upward to the release position, thereby releasing the restriction on the locking part 31 and facilitating the locking part 31 to disengage from the positioning groove 11, thus realizing the height adjustment of the car child seat 100. When locking the head assembly 20, the user can release the force applied to the positioning member 40, and the positioning member 40 moves downward to the positioning position under the elastic action of the elastic member, thereby preventing the locking part 31 from disengaging from the positioning groove 11 and realizing the locking of the head assembly 20. It can be understood that when locking, without user driving, the positioning member 40 can be reset to the positioning position under the action of the elastic member, improving the height adjustment efficiency of the car child seat 100.

[0049] Referring to Figures 3 to 5, in some embodiments of this application, the locking member 30 and the positioning member 40 surround and form an installation space 50, which is suitable for the elastic member to be disposed therein; in this way, the elastic member can be protected and prevented from being affected by the external environment.

[0050] Furthermore, the locking member 30 has a first mounting post 36 on the side facing the positioning member 40, and the positioning member 40 has a second mounting post 43 on the side facing the locking member 30. The first mounting post 36 and the second mounting post 43 are opposite each other in the vertical direction. The upper end of the elastic member can be sleeved and fixed to the first mounting post 36, and the lower end of the elastic member can be sleeved and fixed to the second mounting post 43. The installation of the mounting posts can greatly improve the working stability of the elastic member. Also, at least one of the locking member 30 and the positioning member 40 has a guide portion. The guide portion extends in the vertical direction and includes a first guide portion 44 and a second guide portion 45. The first guide portion 44 and the second guide portion 45 are vertically opposite each other in the vertical direction, forming a guide space between them. The elastic member can be placed within the guide space. The guiding effect of the first guide portion 44 and the second guide portion 45 can further improve the working stability of the elastic member.

[0051] Referring to Figures 1 to 5, in some embodiments of this application, the locking member 30 has a first limiting part 34, and the positioning member 40 has a second limiting part 41. When in the positioning position, the first limiting part 34 and the second limiting part 41 are limited, and when in the release position, the first limiting part 34 and the second limiting part 41 are misaligned. In this way, the locking member 30 and the positioning member 40 can be easily disassembled and assembled, and the assembly efficiency can be improved.

[0052] In detail, the locking member 30 and the positioning member 40 can be assembled in a horizontal direction. The locking member 30 has a first limiting portion 34, and the positioning member 40 has a second limiting portion 41. The positioning member 40 can move relative to the locking member 30 in a vertical direction to move between a positioning position and a release position. When the positioning member 40 is in the positioning position, the first limiting portion 34 of the locking member 30 limits the second limiting portion 41 of the positioning member 40 to prevent the positioning member 40 from disengaging from the locking member 30. When the positioning member 40 is in the release position, the locking member 30... The first limiting part 34 of the 0 is offset from the second limiting part 41 of the positioning member 40; thus, during installation, the positioning member 40 can be assembled on the locking member 30, and the positioning member 40 can be moved to the positioning position under the action of the elastic member. At this time, with the cooperation of the first limiting part 34 and the second limiting part 41, the positioning member 40 can be stably installed on the locking member 30, and during disassembly, the elastic force of the elastic member can be overcome to drive the positioning member 40 to move to the release position, at which time the positioning member 40 can be removed from the locking member 30.

[0053] Referring to Figures 1 to 8, in some embodiments of this application, the backrest assembly 10 has a first socket portion 13, and the headrest assembly 20 has a second socket portion 21. The first socket portion 13 and the second socket portion 21 extend in the vertical direction and are movably engaged. Specifically, in conjunction with the aforementioned embodiments, a plurality of positioning grooves 11 are distributed in the vertical direction. The height adjustment of the headrest assembly 20 relative to the backrest assembly 10 is achieved through the engagement of the locking member 30 with the positioning grooves 11. In order to further improve the stability of the adjustment, the backrest assembly 10 can have a first socket portion 13, and the headrest assembly 20 can have a second socket portion 21. Both the first socket portion 13 and the second socket portion 21 extend in the vertical direction and are movably engaged, so that the first socket portion 13 and the second socket portion 21 can move relative to each other in the vertical direction, thereby improving the adjustment stability of the car child seat 100.

[0054] Referring to Figures 1 to 8, in some embodiments of this application, the backrest assembly 10 has a first positioning part 14, and the headrest assembly 20 has a second positioning part 22. The first positioning part 14 and the second positioning part 22 extend in the vertical direction, and the first positioning part 14 and the second positioning part 22 are inserted and engaged, and can be disengaged; this arrangement can improve the height adjustment stability of the car child seat 100.

[0055] Specifically, one of the first positioning part 14 and the second positioning part 22 can be configured as a guide post and the other can be configured as a guide groove. The guide post can be detachably inserted into the guide groove, and both the guide post and the guide groove extend in the vertical direction. Through the cooperation of the guide post and the guide groove, the stability of the head assembly 20 moving in the vertical direction relative to the back assembly 10 can be improved.

[0056] In addition, in some specific examples, the head assembly 20 is connected to the locking member 30 by a fastener, which can be configured as the aforementioned first positioning part 14, and a clearance groove is constructed on the back assembly 10. The clearance groove can be configured as the aforementioned second positioning part 22. In this way, when the head assembly 20 moves up and down relative to the back assembly 10, the clearance groove can make way for the fastener, thus avoiding structural interference.

[0057] Referring to Figures 1 to 7, in some embodiments of this application, one of the locking member 30 and the backrest assembly 10 is provided with a limiting block 35, and the other is provided with a limiting groove 15. The limiting groove 15 extends in the vertical direction, and the limiting block 35 is slidably disposed in the limiting groove 15; thus, the height adjustment stability of the car child seat 100 can be improved.

[0058] Specifically, the limiting block 35 is slidably disposed in the limiting groove 15, which extends in the vertical direction. The limiting groove 15 can guide the limiting block 35 to move stably in the vertical direction, thereby enabling the head assembly 20 to move stably relative to the back assembly 10 in the vertical direction, thus improving the adjustment stability of the car child seat 100.

[0059] Referring to Figures 1 to 6, in some embodiments of this application, the positioning member 40 has a hand groove 42, which is suitable for the user to drive the positioning member 40 by hand; specifically, the user can place their fingers in the hand groove 42, and the hand groove 42 overcomes the elastic force of the elastic member, thereby driving the positioning member 40 to move to the release position, so as to facilitate the user to adjust the height of the car child seat 100.
