The adjusting mechanism 4 includes two groups of fixing components, a mounting frame 401, a lead screw 402, a threaded barrel 403, a moving component and two groups of guiding components. The fixing components are provided on the backrest frame 1, the mounting frame 401 is provided on the fixing components, the lead screw 402 is rotatably embedded in the top of the outer wall of the mounting frame 401, the threaded barrel 403 is embedded in the bottom of the outer wall of the headrest main body 2, and the threaded barrel 403 is threadedly connected to the outer wall of the lead screw 402. The moving component is provided in the mounting frame 401, and each group of guiding components is provided on the mounting frame 401.

[0027] In this implementation scheme: by cooperating the installation mechanism 3 with the fixing components on the adjusting mechanism 4, the headrest main body 2 can be installed on the backrest frame 1, which is convenient for disassembling and replacing the headrest main body 2 to prevent the installation and disassembly of the headrest main body 2 from being troublesome. By driving the lead screw 402 to rotate through the moving component in the mounting frame 401, the threaded barrel 403 can drive the headrest main body 2 to rise and fall, and the height of the automobile seat headrest can be adjusted to facilitate people of different heights to ride and improve the comfort of the automobile seat.

[0028] Specifically, the driving component includes a bidirectional threaded rod 302 and two mounting plates 303. Each mounting plate 303 is fixedly arranged on one side of the outer wall of the backrest frame 1, and the bidirectional threaded rod 302 is rotatably embedded between the two mounting plates 303.

[0029] In this embodiment: through the mounting plate 303, it is used for the installation and placement of the bidirectional threaded rod 302. By rotating the bidirectional threaded rod 302 between the two mounting plates 303, the two fixing rods 301 can be driven to approach or move away from each other.

[0030] Specifically, each fixing rod 301 is threadedly connected to the outer wall of the bidirectional threaded rod 302, and each fixing rod 301 is slidably embedded on one side of the outer wall of the backrest frame 1.

[0031] In this embodiment: as the fixing rod 301 moves, the fixing rod 301 can enter the fixing hole 405. A sliding groove is provided on one side of the outer wall of the backrest frame 1 to play a guiding role for one end of the fixing rod 301.
