DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar meta-subjects or meta-subjects with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The utility model provides a child seat 100 for a car, which can adjust the relative position between a headrest body 20 and a backrest body 10 to meet user needs.

[0028] Reference Figures 1 to 6 According to the child seat 100 of the car of the embodiment of the utility model, the child seat 100 of the car includes a backrest body 10, a headrest body 20 and a locking mechanism 30. The headrest body 20 is arranged on the backrest body 10 and is movable. The locking mechanism 30 is rotatably connected to the headrest body 20 and is detachably connected to the backrest body 10, and is used to lock the headrest body 20 and unlock the headrest body 20; wherein, the locking mechanism 30 is connected to the backrest body 10 when locked, and is detached from the backrest body 10 when unlocked; in this way, the relative position between the backrest body 10 and the headrest body 20 can be adjusted by the locking mechanism 30 to meet the needs of users.

[0029] Specifically, the locking mechanism 30 is rotatably connected to the headrest body 20, and is used to connect and disengage the locking mechanism 30 from the backrest body 10; wherein, the locking mechanism 30 can be rotated relative to the headrest body 20 to move to a position connected to the backrest body 10, and achieve connection with the backrest body 10, thereby locking the headrest body 20 on the backrest body 10; the locking mechanism 30 can also be rotated relative to the headrest body 20 to disengage the locking mechanism 30 from the backrest body 10, thereby releasing the lock on the headrest body 20, at which time the headrest body 20 can move relative to the backrest body 10, thereby achieving adjustment of the relative position between the headrest body 20 and the backrest body 10.

[0030] In addition, the child car seat 100 in the embodiment of the utility model has a simple and reliable structure, which can improve the safety of the user.

[0031] In addition, the locking mechanism 30 and the backrest body 10 can be locked and unlocked through a variety of connection methods; in the first example, the locking mechanism 30 and the backrest body 10 can be locked and unlocked by plugging; in the second example, the locking mechanism 30 and the backrest body 10 can be locked and unlocked by magnetic cooperation.

[0032] According to the first example mentioned above, referring to Figure 2 , Figure 3 and Figure 5 The backrest body 10 has a plurality of positioning grooves 11, and the plurality of positioning grooves 11 are arranged in the up-down direction. When locked, at least a part of the locking mechanism 30 is selectively arranged in the positioning groove 11, and when unlocked, the locking mechanism 30 is disengaged from the positioning groove 11; it can be understood that when it is necessary to lock the headrest body 20, the locking mechanism 30 can be driven to rotate relative to the headrest body 20 so that the locking mechanism 30 moves to a position connected to the backrest body 10, and the backrest body 10 has a plurality of positioning grooves 11, and the locking mechanism 30 can be selectively arranged in the positioning groove 11, thereby cooperating with the positioning groove 11 to achieve locking of the headrest body 20.

[0033] In addition, a plurality of positioning grooves 11 are arranged in the up-down direction. In other words, the locking mechanism 30 can be selectively arranged in the positioning grooves 11 in the up-down direction to facilitate the height adjustment of the headrest body 20 relative to the backrest body 10 in the up-down direction. Of course, according to actual conditions, a plurality of positioning grooves 11 can be arranged in the left-right direction to achieve the adjustment of the headrest body 20 relative to the backrest body 10 in the left-right direction.

[0034] Reference Figure 1 , Figure 3 and Figure 6 In some embodiments of the utility model, the locking mechanism 30 includes a first locking component 30a and a second locking component 30b. The first locking component 30a and the second locking component are respectively rotatably connected to the headrest body 20, and are connected and disconnected from the backrest body 10 by clamping. In this way, the locking stability of the locking mechanism 30 on the headrest body 20 can be improved.

[0035] In detail, the first locking assembly 30a and the second locking assembly 30b can be rotatably connected to the headrest body 20 respectively, and the first locking assembly 30a is arranged on the left side of the backrest body 10, and the second locking assembly 30b is arranged on the right side of the backrest body 10; in the process of locking the headrest body 20, the first locking assembly 30a can be rotated counterclockwise relative to the headrest body 20 to a position connected to the backrest body 10, and the second locking assembly 30b can be rotated clockwise relative to the headrest body 20 to a position connected to the backrest body 10, so that the headrest body 20 is clamped in the form of a clamp. 0 is locked on the backrest body 10; in the process of unlocking the headrest body 20, the first locking component 30a can rotate clockwise relative to the headrest body 20 to disengage from the backrest body 10, and the second locking component 30b can rotate counterclockwise relative to the headrest body 20 to disengage from the backrest body 10, thereby releasing the headrest body 20 to achieve unlocking of the headrest body 20; therefore, the first locking component 30a and the second locking component 30b are connected and disengaged from the backrest body 10 in a clamping manner, which can improve the locking stability of the locking mechanism 30 on the headrest body 20.

[0036] In combination with the above, the first locking component 30a can be selectively disposed in the positioning groove 11, and the second locking component 30b can be selectively disposed in the positioning groove 11, so as to realize that the locking mechanism 30 locks the headrest body 20; the first locking component 30a can be separated from the positioning groove 11, and the second locking component 30b can be separated from the positioning groove 11, so as to release the locking mechanism 30 from the headrest body 20. Of course, in combination with the above, the first locking component 30a and the second locking component 30b can also realize the locking and unlocking of the headrest body 20 by magnetic cooperation.
