Side plates 204 are fixedly connected to the side of the headrest plate 201. Lead screws 205 are rotatably connected inside the sides of the two vertical plates 202. One end of the lead screw 205 passes through the side of one vertical plate 202 and is fixedly connected to the output shaft of the drive motor 203. Support rods 206 are fixedly connected inside the sides of the two vertical plates 202. The number of support rods 206 is two. Two support rods 206 are symmetrically distributed on both sides of the upright plate 202. The side of the lead screw 205 is threadedly connected to the moving block 207. The moving block 207 is slidably connected to the two support rods 206. The side of the side plate 204 is fixedly connected to the rotating shaft 208. The top surface of the moving block 207 is fixedly connected to the fixing groove 209. There are three fixing grooves 209. The side of one fixing groove 209 is rotatably connected to the rotating cylinder 210. The rotating cylinders 210 are in pairs. The side of the rotating cylinder 210 is fixedly connected to the protrusion 211. There are multiple protrusions 211 and they are evenly distributed on the side of the rotating cylinder 210. The surface of the side plate 204 is fixedly connected to the memory foam 212. The surface of the memory foam 212 is fixedly connected to the leather sleeve 213.

[0028] In this embodiment, the headrest plate 201 connects to two side plates 204 for support. The two side plates 204 are connected to memory foam 212 and a leather cover 213 to support the passenger's head. The memory foam 212 and leather cover 213 improve the comfort of the passenger's head. Two upright plates 202 connect to a lead screw 205 and a support rod 206 for support. The drive motor 203 is started to rotate the lead screw 205. When the lead screw 205 rotates, it drives the moving block 207 to move left and right along the two support rods 206. The two support rods 206 are connected to the moving block 207 to provide support for the moving block 207. The support rods 206 prevent the lead screw 205 from bending and deforming when the moving block 207 is subjected to large forces. At the same time, the connection between the two support rods 206 and the moving block 207 can improve the moving stability of the moving block 207. When the moving block 207 moves, it drives the three fixed grooves 209 to move. The rotating cylinder 210 is movably connected to the memory foam 212. When the moving block 207 moves, it drives the three sets of rotating cylinders 210 to rotate through the three fixed grooves 209. The surface of the rotating cylinder 210 is connected to the protrusion 211. When the rotating cylinder 210 and the protrusion 211 rotate, they drive the memory foam 212 and the leather cover 213 to deform, thereby achieving the effect of massaging the passenger's head and improving the passenger's comfort.

[0029] Example 2

[0030] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the support mechanism 1 includes a connecting frame 101, threaded holes 102 are provided on both sides of the bottom surface of the connecting frame 101, connecting rods 103 are threadedly connected to the inside of the two threaded holes 102, and a locking groove 104 is fixedly connected to the upper side of the connecting frame 101.

[0031] In this embodiment, by connecting two connecting rods 103 to threaded holes 102, the two connecting rods 103 are inserted into the car seat after the connection is completed. The connection between the connecting rods 103 and the car seat supports the connecting frame 101. The connecting frame 101 is connected to the rotating shaft 208 to support the massage headrest device. Rotating the massage headrest device can drive the rotating shaft 208 to rotate in the connecting frame 101, thereby adjusting the rotation angle of the massage headrest device for the convenience of different passengers.

[0032] Example 3

[0033] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a connecting shaft 105 is rotatably connected inside the locking groove 104, the connecting shaft 105 is fixedly connected to the rotating shaft 208, a slot 106 is provided on the side of the connecting shaft 105, a return spring 107 is fixedly connected inside the locking groove 104, a slider 108 is slidably connected inside the locking groove 104, the return spring 107 is fixedly connected to the slider 108, a fixing post 109 is fixedly connected to the side of the slider 108, and a locking block 110 is fixedly connected to the top surface of the slider 108, the locking block 110 cooperates with the slot 106.

[0034] In this embodiment, rotating the massage headrest device pulls the fixing post 109, causing the slider 108 to descend. As the slider 108 descends, it causes the locking block 110 to disengage from the slot 106 and causes the return spring 107 to contract. Rotating the massage headrest device causes the connecting shaft 105 to rotate in the locking groove 104 via the rotating shaft 208. The locking groove 104 is connected to the connecting shaft 105 to restrict the position of the connecting shaft 105. After the massage headrest device rotates to a suitable angle, the fixing post 109 is released, and the return spring 107 relaxes, causing the slider 108 to rise in the locking groove 104. As the slider 108 rises, it causes the locking block 110 to engage in the slot 106. The locking block 110 is connected to the slot 106 to restrict the rotation of the connecting shaft 105. The connecting shaft 105 is connected to the rotating shaft 208 to fix the rotation angle of the massage headrest device.

[0035] The working principle of this split-type car seat headrest structure will be explained in detail below.

[0036] like Figure 1-6As shown, by connecting two connecting rods 103 to threaded holes 102, after the connection is completed, the two connecting rods 103 are inserted into the car seat. The connecting rods 103 are connected to the car seat to support the connecting frame 101. The connecting frame 101 is connected to the rotating shaft 208 to support the massage headrest device. When the massage headrest device is rotated, the fixed column 109 is pulled, causing the slider 108 to descend. When the slider 108 descends, it causes the locking block 110 to disengage from the locking slot 106 and causes the return spring 107 to retract. Rotating the massage headrest device allows... The rotating shaft 208 drives the connecting shaft 105 to rotate in the locking groove 104. The locking groove 104 is connected to the connecting shaft 105 to restrict the position of the connecting shaft 105. After the massage headrest device rotates to a suitable angle, the fixing post 109 is released, the return spring 107 relaxes, and the slider 108 rises in the locking groove 104. The rise of the slider 108 causes the locking block 110 to engage in the locking groove 106. The locking block 110 is connected to the locking groove 106 to restrict the rotation of the connecting shaft 105. The connecting shaft 105 is connected to the rotating shaft 208 to regulate the position of the massage headrest. The rotation angle of the headrest device is fixed. The headrest plate 201 is connected to the memory foam 212 and the leather cover 213 through two side plates 204 to support the passenger's head. The drive motor 203 is started to drive the lead screw 205 to rotate. When the lead screw 205 rotates, it drives the moving block 207 to move left and right along the two support rods 206. The two support rods 206 are connected to the moving block 207 to provide support for the moving block 207 and prevent the lead screw 205 from bending and deforming when the moving block 207 is subjected to large forces. At the same time, the two support rods 206 The connection with the movable block 207 can improve the movement stability of the movable block 207. When the movable block 207 moves, it drives the three fixed grooves 209 to move. The rotating cylinder 210 is movably connected to the memory foam 212. When the movable block 207 moves, it drives the three sets of rotating cylinders 210 to rotate through the three fixed grooves 209. The surface of the rotating cylinder 210 is connected to the protrusion 211. When the rotating cylinder 210 and the protrusion 211 rotate, they drive the memory foam 212 and the leather cover 213 to deform, thereby achieving the effect of massaging the passenger's head and improving the passenger's comfort.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
