[0032] like Figure 5 and Figure 6 As shown, the outer fabric layer 11 is sewn and installed with the surface of the headrest frame so that the inner surface of the outer fabric layer 11 contacts the surface of the support block 6, the adjustment block 4 penetrates the surface of the outer fabric layer 11, and the device is connected to the car seat using a fixing strap 10 with an elastic band structure. At this time, the user contacts the flexible adjustment block 4 on the surface of the outer fabric layer 11, and the flexible support block 6 contacts the user's head and neck through the outer fabric layer 11. The spherical structure of the adjustment block 4 and the support block 6 can increase the user's comfort.

[0033] The connecting block 1 is a spherical structure, and a frame structure is arranged on one side surface of the connecting block 1. The frame structure is provided with an adjusting rod 2 and a supporting rod 5 to constitute the basic frame of the automobile headrest and realize the adjustment function at the same time. The frame structure includes an adjusting rod 2, and the adjusting rod 2 is fixedly installed on the outer surface of the connecting block 1. The inner wall of the adjusting rod 2 is threadedly connected with an adjusting rod 2 3, and the other end of the adjusting rod 2 3 is fixedly installed with an adjusting block 4. The surface of the adjusting block 4 is a flexible material, and the adjusting block 4 is a spherical structure.

The outer surface of the connecting block 1 is fixedly installed with a supporting rod 5, and the supporting rod 5 is a telescopic structure. The end of the supporting rod 5 is fixedly installed with a supporting block 6, and the supporting block 6 is a compressible elastic material. The block 6 is spherical, the support rod 5 and the support block 6 constitute a support member of the headrest frame, the support member composed of the support rod 5 and the support block 6 is arranged in a fan shape with the connecting block 1 as the center, and the support member is symmetrically arranged on the upper and lower surfaces of the adjusting member, the outer surfaces of the adjusting rod 1 2 and the adjusting rod 2 3 are provided with a buffer spring 7, the two ends of the buffer spring 7 are respectively in contact with the surfaces of the connecting block 1 and the adjusting block 4, the outer surfaces of the adjusting rod 2 3 and the support rod 5 are slidably provided with a connecting rod 1 8, the connecting rod 1 8 is an arc structure, and the connecting rod 1 8 is a compressible elastic material, the connecting rod 1 8, the connecting block 1, the adjusting member and the supporting member together constitute a fan-shaped structure, the connecting block 1 is arranged through the surface of the connecting rod 2 9, and a plurality of fan-shaped structures are arranged in parallel on the surface of the connecting rod 2 9;

The fan-shaped structure can increase the supporting strength of the device. By rotating the adjusting block 4, the adjusting rod 2 3 is driven to rotate by the adjusting block 4. By using the threaded connection of the adjusting rod 2 3 in the adjusting rod 1 2, the length of the adjusting rod 2 3 extending out of the adjusting rod 2 can be achieved, thereby achieving height adjustment of the device. The surface of the adjusting block 4 is made of flexible material, and the flexible adjusting block 4 passes through the surface of the external fabric layer 11, so that the user can adjust the height of the headrest outside the device, thereby increasing the overall practicality.
