[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0018] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0019] like Figures 1 to 3As shown, a car flip headrest includes a bottom box 2, a bottom cover 1 and a frame 3. The bottom cover 1 is provided with a plurality of evenly distributed through holes, and the bottom box 2 is provided with threaded holes at positions corresponding to the through holes, and the through holes are provided with bolts 12, which pass through the through holes and are screwed into the threaded holes. The detachable bottom cover 1 is convenient for inspecting or replacing various components inside the bottom box 2. The frame 3 includes a rotating shaft 31, an L-shaped rod 32 and a fan-shaped card 312, and the rotating shaft 31 is rotatably connected to the bottom box 2 through a lock 311. The rotating shaft 31 is provided with an L-shaped rod 32 and a fan-shaped card 312 that are fixedly connected. One end of the L-shaped rod 32 is assembled into the car seat, and the other end passes through the bottom cover 1 and is welded to the rotating shaft 31, and the fan-shaped card 312 is integrated with the rotating shaft 31. The bottom box 2 is provided with locks 311 at both ends corresponding to the rotating shaft 31, and the locks 311 are provided with screws for easy disassembly or installation. The rotating shaft 31 has a degree of freedom of rotation relative to the bottom box 2, and the L-shaped rod 32 and the fan-shaped card 312 rotate with the rotating shaft 31. The bottom box 2 is provided with a through hole 11 for matching the fan-shaped card 312, and the fan-shaped card 312 can pass through the through hole 11 when rotating to prevent the fan-shaped card 312 from interfering with the bottom box 2.

[0020] A torsion spring 33 is provided on the rotating shaft 31, one end of the torsion spring 33 is fixedly connected to the frame 3, and the other end is in contact with the bottom box 2. When the fan-shaped card 312 is stuck on the lock piece 22, the fan-shaped card 312 is completely fixed, and the torsion spring 33 is deformed and accumulates elastic potential energy. The lock piece 22 is provided with an opening 224 corresponding to the fan-shaped card 312. When the fan-shaped card 312 moves to the opening 224, the fan-shaped card 312 has the degree of freedom of circumferential rotation, the torsion spring 33 releases the elastic potential energy, and the fan-shaped card 312 rotates around the rotating shaft 31, and the fan-shaped card 312 passes through the opening 224.

[0021] The lock piece 22 is provided with a U-shaped inclined groove 223, and a column 222 is provided at a position of the bottom box 2 corresponding to the U-shaped inclined groove 223. The column 222 passes through the lock piece 22 and contacts the bottom cover 1. The lock piece 22 is located between the bottom cover 1 and the bottom box 2. The bottom box 2 is provided with a side guide block 221 on the side corresponding to the lock piece 22. The lock piece 22 moves along the fitting surface of the side guide block 221 and the lock piece 22 under the cooperation of the column 222 and the side guide block 221. The lock piece 22 is provided with a tension spring 23, one end of the tension spring 23 is fixedly connected to the lock piece 22, and the other end is fixedly connected to the bottom box 2. The extension direction of the tension spring 23 is parallel to the fitting surface of the side guide block 221 and the lock piece 22. Under the action of the tension spring 23, the lock piece 22 can automatically recover after the position is changed.

[0022] A button 21 is provided on the side of the lock piece 22, one end of which passes through the side of the bottom box 2 and contacts the side of the lock piece 22, and the button 21 is slidably connected with the bottom box 2. When the button 21 is moved into the bottom box 2, the button 21 drives the lock piece 22 to move, the tension spring 23 is stretched and deformed, and the fan-shaped card 312 on the skeleton 3 moves relative to the lock piece 22 to the opening 224. Under the action of the torsion spring 33, the skeleton 3 rotates around the rotating shaft 31. When restoring the initial position of the skeleton 3 and the bottom box 2, the bottom box 2 is directly rotated, so that the torsion spring 33 is deformed and accumulates elastic potential energy. When the end face of the fan-shaped card 312 is parallel to the side of the lock piece 22, the lock piece 22 is restored to the initial position under the action of the rebound of the tension spring 23, so that the lock piece 22 locks the position of the fan-shaped card 312, and the skeleton 3 no longer rotates.

[0023] The working principle of the specific embodiment of the utility model is as follows: under normal circumstances, the fan-shaped card 312 is stuck on the lock piece 22, and the torsion spring 33 is in a deformed state. When the angle between the frame 3 and the bottom box 2 needs to be changed, the button 21 is moved into the bottom box 2, and the lock piece 22 moves along the side guide block 221 under the drive of the button 21, and the tension spring 23 is stretched and deformed, and the fan-shaped card 312 moves relative to the lock piece 22 to the opening 224. At this time, the shaft 31 has the degree of freedom of circumferential rotation, and the torsion spring 33 releases elastic potential energy, and the fan-shaped card 312 rotates with the shaft 31 and passes through the opening 224, thereby changing the angle between the frame 3 and the bottom box 2.
