Detailed implementation manners

[0029] The following further elaborates on the present application with reference to the accompanying drawings.

[0030] The embodiment of the present application discloses a car seat headrest.

[0031] Refer to Figure 1 , the car seat headrest includes a fixing part 1 and a headrest part 2, and the headrest part 2 is installed on the fixing part 1; during use, the user leans their head on the headrest part 2.

[0032] The fixing part 1 is fixedly connected with a headrest rod 3, and a plurality of card slots 31 are arranged at intervals along the vertical direction on the headrest rod 3, and the card slots 31 can cooperate with the guide sleeve on the seat back; when the headrest rod 3 needs to be lifted or lowered, the headrest rod 3 is moved so that the card slots 31 at different heights cooperate with the guide sleeve on the seat back.

[0033] See Figure 2 , the headrest part 2 includes a headrest cover 21, an airbag group 22 and a support assembly 23, the airbag group 22 is located inside the headrest cover 21, and the airbag group 22 supports the headrest cover 21, so that it is more comfortable for the user to lean on the headrest cover 21; the support assembly 23 is used to squeeze the airbag group 22 so that the airbag group 22 can always be in contact with the inner wall of the headrest cover 21.

[0034] Specifically, the airbag group 22 includes a number of interconnected airbag units 24, and a number of airbag units 24 are all attached to the inner wall of the headrest cover 21, and the airbag units 24 at both ends are sewn and connected to the headrest cover 21 through a thread.

[0035] The support assembly 23 includes an elastic support sheet 231 and an ejector rod 232. The elastic support sheet 231 is made of plastic material and has a certain toughness and elasticity. The elastic support sheet 231 protrudes towards the airbag group 22 and squeezes the airbag group 22 so that the airbag group 22 is always in contact with the inner wall of the headrest cover 21.

[0036] The fixing part 1 has an accommodation cavity 11 inside, and a cover plate 12 covering the opening of the accommodation cavity 11 is provided. The cover plate 12 is fixedly connected to the fixing part 1 by screws.

[0037] See Figure 2 And Figure 3 , the fixing part 1 is provided with two clamping plates 4. The upper and lower ends of the elastic support piece 231 are respectively inserted into the two clamping plates 4 and then fixedly connected by screws, and the elastic support piece 231 is supported by the clamping plates 4. The cover plate 12 is provided with a relief groove 13 for the clamping plate 4 to pass through. The clamping plate 4 passes through the relief groove 13 and enters the accommodation cavity 11 of the fixing part 1 and is connected to the fixing part 1 by bolts.

[0038] One end of the ejector rod 232 is located inside the fixing part 1, and the other end passes through the cover plate 12 and abuts against the elastic support piece 231. By the action of the ejector rod 232 on the elastic support piece 231, the airbag group 22 can always be in close contact with the headrest cover 21.

[0039] To facilitate the force of the ejector rod 232 to act better on the elastic support piece 231, one end of the ejector rod 232 close to the elastic support piece 231 has an arc surface 233, and the side of the elastic support piece 231 away from the airbag group 22 has an arc leaning surface 234 that abuts against the arc surface 233; during use, the arc surface 233 of the ejector rod 232 abuts against the arc leaning surface 234 of the elastic support piece 231, making the contact between the ejector rod 232 and the elastic support piece 231 more stable.

[0040] See Figure 2 And Figure 4 , to facilitate adjusting the position where the ejector rod 232 acts on the elastic support piece 231, a rotating motor 5 is arranged in the accommodation cavity 11 of the fixing part 1. The rotating motor 5 is fixedly connected to the fixing part 1 by screws. The output shaft of the rotating motor 5 radially passes through the ejector rod 232, so that the rotating motor 5 can drive the end of the ejector rod 232 away from the fixing part 1 to swing up and down, so that the position where the ejector rod 232 acts on the elastic support piece 231 can be adjusted, and further the position where the elastic support piece 231 protrudes from the airbag group 22 can be changed to adapt to different people leaning on the headrest part 2. In this embodiment, the rotating motor 5 is a stepping motor with a self-locking function. When the rotating motor 5 is not in use, it cannot rotate conventionally, that is, the ejector rod 232 cannot swing when the rotating motor 5 is not started.

[0041] The cover plate 12 is provided with a rotating hole 14 for the ejector rod 232 to pass through, and the range of the rotating hole 14 is relatively large so that the ejector rod 232 can swing.

[0042] The implementation principle of a car seat headrest in an embodiment of the present application is as follows: Under normal conditions, the ejector rod 232 acts on the elastic support sheet 231, the elastic support sheet 231 acts on the airbag group 22, and the airbag group 22 provides support for the headrest cover 21, so as to support the neck of the passenger; When different passengers use the headrest, the rotation motor 5 is started, and the rotation motor 5 drives the ejector rod 232 to swing, so that the position where the ejector rod 232 acts on the elastic support sheet 231 is changed, so as to adapt to different people leaning on the headrest part 2.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
