[0033] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used in the present invention are for illustrative purposes only.

[0034] like Figure 1-11 As shown, the present embodiment provides a headrest, comprising a headrest body 1, pillow wings 2 and an eye massage mechanism 3, the pillow wings 2 are respectively located on both sides of the headrest body 1, and the pillow wings 2 are rotatably connected to the headrest body 1, the eye massage mechanism 3 is connected to the pillow wings 2, and a receiving cavity (not shown) is further provided in the headrest body 1; further, when the eye massage mechanism 3 enters a use state, the eye massage mechanism 3 extends upward from the receiving cavity, and the pillow wings 2 rotate relative to the headrest body 1 and drive the eye massage mechanism 3 to flip to the position of the human eye, so that the headrest has the function of massaging the human eye; similarly, when the eye massage mechanism 3 exits the use state, the pillow wings 2 rotate relative to the headrest body 1 and drive the eye massage mechanism 3 to leave the human eye position, that is, the eye massage mechanism 3 flips upward, and finally, the eye massage mechanism 3 shrinks and is stored in the receiving cavity, thereby completing the hiding of the eye massage mechanism 3, thereby avoiding the massage device from affecting the driver and passengers or avoiding the massage device from being damaged by collision.

[0035] like Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, in a preferred embodiment, the headrest body 1 includes a supporting portion 11, a rear cover body 12 and a first driving mechanism. The supporting portion 11 is used to support the human head, the rear cover body 12 and the supporting portion 11 together form a accommodating cavity, and the rear cover body 12 is rotatably connected to the supporting portion 11; the first driving mechanism is located in the accommodating cavity and is fixedly connected to the supporting portion 11, and the first driving mechanism is transmission-connected to the rear cover body 12, and the first driving mechanism is used to drive the rear cover body 12 to open or close the accommodating cavity.

[0036] like Figure 4-6 As shown in , 8-9, in the preferred embodiment, it also includes a second driving mechanism, which is located in the accommodating cavity and fixed to the supporting portion 11 by bolts, and the pillow wing 2 is in transmission connection with the second driving mechanism, that is, the second driving mechanism is used to drive the pillow wing 2 to rotate relative to the headrest body 1 and finally drive the eye massage mechanism 3 to flip relative to the headrest body 1. Furthermore, a lifting mechanism is also provided in the pillow wing 2, which is fixed to the pillow wing 2 by bolts, the eye massage mechanism 3 is connected to the lifting mechanism, and the second driving mechanism is in transmission connection with the lifting mechanism, and the lifting mechanism is used to drive the eye massage mechanism 3 to extend or retract from the accommodating cavity of the headrest body 1.

[0037] like Figure 1-3 As shown, in a preferred embodiment, a protrusion 21 is further provided on the pillow wing 2, and the protrusion 21 is close to the supporting portion 11. Specifically, the protrusion 21 is located on both sides of the supporting portion and is inclined relative to the supporting portion 11, wherein a speaker 22 is also provided in the protrusion 21; when playing music, left and right channels can be formed, or it can be matched with other speakers installed in the car to form different sound field levels, thereby improving the music listening effect.

[0038] like Figure 7-8As shown, in a preferred embodiment, specifically, the first driving mechanism includes a frame (not shown), an A1 gear 102, an A2 gear 106, a driving wheel 107, and a lock 108, wherein the A1 gear 102, the A2 gear 106 and the driving wheel 107 are meshed in sequence, and the A2 gear 106, the driving wheel 107 and the lock 108 are all rotatably connected to the frame; it also includes a first driving motor 101, an A8 gear 103, a fan gear 104 and a transmission shaft 105, the first driving motor 101 is fixed to the frame by bolts, the driving shaft of the first driving motor 101 is connected to the A1 gear 102, and the A1 gear is meshed with the A8 gear 103, the A8 gear 103 is meshed with the fan gear 104, and the transmission shaft 105 is connected to the A8 gear 103, and the transmission shaft 105 is rotatably connected to the frame; wherein the lock 108 is used to lock or unlock the rear cover body 12. Furthermore, the rotation of the pillow wing 2 is driven by the first driving motor 101 to drive the A1 gear 102 to rotate, and then drive the A8 gear 103 connected to both ends of the transmission shaft 105 to rotate synchronously, and then drive the fan gear 104 meshing with it to rotate, and at the same time, the fan gear 104 drives the pillow wing 2 connected to it to rotate, that is, the pillow wing 2 reciprocates relative to the headrest body 1. Further, the opening of the rear cover body 12 is linked according to the difference in the rotation angle of the fan gear 104 and the working position. When the pillow wing 2 rotates backward about 18 degrees relative to the headrest body 1 and reaches the preset position where the eye massage mechanism 3 slides out of the accommodating cavity in the headrest body 1, the A1 gear 102 drives the driving wheel 107 to rotate about 58 degrees through the A2 gear 106, and the driving wheel 107 drives the rear cover body 12 to open relative to the supporting part 11. Further, when the push wheel 107 rotates about 3°, the cam structure on the edge of the push wheel 107 pushes the lock 108 open, and the rear cover 12 and the lock 108 are in an unlocked state. As the push wheel 107 continues to rotate, the rear cover 12 begins to rotate relative to the hinge point around the support portion 11. When the rear cover 12 rotates to 22°, the pillow wing 2 stops rotating backwards. At this time, the eye massage mechanism 3 begins to extend upward from the accommodating cavity. After running to a predetermined distance, the pillow wing 2 begins to rotate backwards (towards the human eye position). At this time, the push wheel starts to rotate in the opposite direction at the same time. The rear cover 12 is closed under the reaction force of the torsion spring on the rear cover shaft 202, and is locked with the lock 108. When the eye massage mechanism 3 needs to be retracted into the accommodating cavity, the opening and closing actions of the rear cover 12 are repeated once, and the unlocking and locking of the lock 108 are repeated once.

[0039] like Figure 4 , 5As shown in FIG. 9 , further, the lifting mechanism in the eye massage mechanism 3 is provided with a second drive motor 301 which provides a forward and reverse rotation motion and then converts it into a linear reciprocating motion, wherein a Hall component (not shown) is provided at the second drive motor 301 for counting the number of rotations of the motor, and obtaining the number of rotations of the motor, so as to accurately control the lifting mechanism and further control the distance and position of the linear motion of the eye massage mechanism 3. Specifically, an A3 gear 303 is connected to the driving shaft of the second driving motor 301, an A4 gear 304 is connected to the transmission shaft 305, the transmission shaft 305 is rotatably connected to the frame, the second driving motor 301 is fixed to the frame by bolts, and the A3 gear and the A4 gear 304 are meshed with each other, and both ends of the transmission shaft 305 are also connected to A5 gears 308, that is, the A3 gear 303 and the A4 gear 304 drive the A5 gears 308 at both ends of the transmission shaft 305 to rotate synchronously; the pillow wings 2 located on both sides of the headrest body 1 are also rotatably connected to the wire wheel gear 309, the A5 gear 308 is meshed with the wire wheel gear 309, the diameter of the A5 gear 308 is smaller than the wire wheel gear 309, thereby forming a reduction transmission, and the A5 gear 308 and the wire wheel gear 309 are subjected to a certain reduction ratio, so that the wire wheel 310 rotates by an angle of about 350° in the total working stroke of the eye mechanism 5. A wire wheel 310 is coaxially fixed on the wire wheel gear 309, and a pull wire 313 is transmission-connected to the wire wheel 310. A terminal is provided in the middle of the pull wire 313 and fixed to the eye connection block 501. Through the action of the tensioning wheel 312, the pull wire 313 is always kept at a certain pre-tightening force. When the wire wheel 310 rotates forwards and reversely, it drives the pull wire 313, thereby making the lifting mechanism move back and forth in a straight line, that is, driving the eye massage mechanism 3 to rise or retract from the accommodating cavity.

[0040] like Figure 9-12As shown, in a preferred embodiment, a neck massager is also included, which is connected to the headrest body 1 and is used to massage the neck. A telescopic mechanism is also included, which is located in the accommodating cavity and fixedly connected to the supporting portion 11. The neck massage mechanism is connected to the telescopic mechanism, and the telescopic mechanism is used to drive the neck massage mechanism to extend or retract from the supporting portion 11. Specifically, the telescopic mechanism includes a third drive motor 201, an A6 gear 202, an A7 gear 203, a screw rod 204, a slider 205, a massage head 206, a Hall sensor 207, a buffer spring 208, and a slide 210. The slider 205 is slidably connected to the slide 210, and the slide 210 is fixed to the headrest body 1 by bolts. The A6 gear 202 is transmission-connected to the drive shaft of the third drive motor 201, and the third drive motor 201 is fixed to the slide 210 by bolts. The A7 gear 203 is connected to the screw rod 204, and the screw rod 204 is screwed with the slider 205 by threads, and the A7 gear 203 is meshed with the A6 gear 202; The head 206 is slidably connected to the slider 205, and the buffer spring 208 is located between the massage head 206 and the slider 205. When the human neck squeezes the massage head 206, the buffer spring 208 can provide a certain elastic support force or form a flexible support, thereby improving the comfort of the neck massager. The Hall sensor 207 is fixed to the third drive motor 201 by bolts. The Hall sensor 207 is used to count the number of rotations of the third drive motor 201, that is, to obtain the number of rotations of the third drive motor 201, so as to control the distance of the slider 205 extending or retracting relative to the headrest body 1 by accurately controlling the number of rotations of the screw rod 204. The massage head 206 in this embodiment is an electrode sheet and at least two are set, and the massage heads 206 are arranged at intervals. The massage heads 206 use the pulse electric signal generated by the microcomputer control and form a loop between the two massage heads (electrode sheets). The pulse electricity of the human body causes the human muscles to contract, thereby simulating massage effects such as acupuncture, cupping, scraping, massage, hammering, and massage. The eye massage mechanism 3 inflates and deflates the airbags through an air pump, that is, the eyes of a person are squeezed by the inflation and deflation of the airbags, thereby simulating a massage effect.
