The structure is simple, reasonable and easy to operate.
[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 5 shown, it should be known that a seat mounting plate 3 is fixedly installed inside the car seat. A pair of headrest rods 31 are slidably arranged on the side of the seat mounting plate 3. The pair of headrest rods 31 extend into the headrest body 1 and are connected to the headrest body 1. By setting the pair of headrest rods 31, the headrest body 1 can be better supported and adjusted, improving the reliability and stability of the device.
[0028] In this embodiment, as Figure 2 and Figure 5 shown, it should be known that in order to better limit the sliding of the two headrest rods 31, headrest guide sleeves 32 are installed on both sides of the seat mounting plate 3. The pair of headrest rods 31 are sleeved inside the headrest guide sleeves 32, so as to stably support and limit the headrest rods 31.
[0029] In this embodiment, as Figures 1 to 3 and Figures 5 to 6 shown, it should be known that the headrest body 1 includes a headrest rear cover 11, a rear cover mounting plate 13 and a sleep headrest 12. The rear cover mounting plate 13 is installed inside the headrest rear cover 11. The bottom end of the headrest rear cover 11 is connected to the top ends of the two headrest rods 31. The sleep headrest 12 is slidably installed on the rear cover mounting plate 13, which is convenient for making the overall device have certain stability and safety.
[0030] In this embodiment, as Figure 1 , Figure 5 and Figure 6 shown, it can be understood that in order to make people more comfortably rest on the headrest body 1, comfort covers are arranged on the sides of the headrest rear cover 11 and the sleep headrest 12. By setting the comfort covers, the head of a person can be better protected and the comfort of a person can be improved at the same time. At the same time, setting the comfort covers can improve the overall aesthetics.
[0031] In this embodiment, asFigures 2 to 6 As shown, the adjustment mechanism 2 includes an up-and-down adjustment structure 21 and a front-and-back adjustment structure 22; the up-and-down adjustment structure 21 is installed on the side of the seat mounting plate 3 and cooperates with a pair of headrest rods 31. By providing the up-and-down adjustment structure 21, the up-and-down adjustment structure 21 can drive a pair of headrest rods 31 to slide up and down within the headrest guide sleeve 32, thereby driving the headrest body 1 to move up and down, improving the practicability and safety of the device; the front-and-back adjustment structure 22 is arranged within the rear cover mounting plate 13, and the front-and-back adjustment structure 22 cooperates with the sleep headrest 12. By providing the front-and-back adjustment structure 22, the front-and-back adjustment structure 22 can drive the sleep headrest 12 to move back and forth within the rear cover mounting plate 13, so that the sleep headrest 12 can adapt to the user's head, thereby improving the comfort and stability of the user's head.
[0032] In this embodiment, as Figure 2 、 Figure 3 and Figure 5 shown, the up-and-down adjustment structure 21 includes an up-and-down moving slider 211, an up-and-down moving motor 212, and an up-and-down screw rod guide 213; the up-and-down moving slider 211 is sleeved outside a pair of headrest rods 31 through a snap spring, the up-and-down moving motor 212 is installed on the seat mounting plate 3, and the up-and-down screw rod guide 213 is arranged within the up-and-down moving slider 211 and connected to the output end of the up-and-down moving motor 212; when adjusting the headrest body 1 up and down, the up-and-down moving motor 212 can be driven at this time. The up-and-down moving motor 212 rotates to drive the up-and-down screw rod guide 213 to rotate. The rotation of the up-and-down screw rod guide 213 can cause the up-and-down moving slider 211 to drive a pair of headrest rods 31 to move up and down within the headrest guide sleeve 32, thereby enabling the headrest body 1 to move up and down, facilitating better up-and-down adjustment of the headrest body 1, and improving the practicability and safety of the device.
[0033] In this embodiment, as Figures 2 to 4 and Figure 6 shown, the front-and-back adjustment structure 22 includes a front-and-back moving slider 221, a front-and-back moving motor 222, and a front-and-back screw rod guide 223; the front-and-back moving slider 221 is slidably installed on the rear cover mounting plate 13 and connected to the sleep headrest 12, the front-and-back moving motor 222 is installed within the headrest rear cover 11, and the front-and-back screw rod guide 223 is installed inside the front-and-back moving slider 221 and connected to the output end of the front-and-back moving motor 222; when adjusting the comfort of the headrest body 1, the front-and-back moving motor 222 can drive the front-and-back screw rod guide 223 to rotate at this time. The rotation of the front-and-back screw rod guide 223 can cause the front-and-back moving slider 221 to move back and forth under the limitation of the rear cover mounting plate 13. The movement of the front-and-back moving slider 221 can drive the sleep headrest 12 to move back and forth, thereby facilitating the improvement of the comfort and stability of the device.
[0034] It should be noted that the front-back adjustment of a general headrest is to adjust the headrest by moving the headrest rod 31 back and forth. At this time, an avoidance groove must be provided on the seat so that the headrest rod 31 can move back and forth to drive the headrest to be adjusted back and forth. This will cause an avoidance groove to be provided above the seat, and dust and other sundries in the vehicle can easily enter the seat through the avoidance groove, which can inevitably damage the seat and the devices inside the seat. Therefore, in order to prevent dust from entering and damaging the internal structure of the seat, a rear cover mounting plate 13 is installed on the headrest rear cover 11, and the sleep headrest 12 is slidably arranged in the rear cover mounting plate 13 and connected to the front-back moving slider 221. Therefore, when the adjustment mechanism 2 makes a front-back adjustment, the front-back moving slider 221 can move back and forth in the headrest rear cover 11, thereby driving the sleep headrest 12 to move back and forth, which can prevent the avoidance groove from being provided on the seat, effectively preventing dust and other sundries from entering the seat, and improving the service life of the seat and reducing the maintenance cost.
[0035] It should be noted that the up-down moving motor 212 and the front-back moving motor 222 are electrically connected to the vehicle's control system, so that the up-down adjustment structure 21 and / or the front-back adjustment structure 22 can be started through the vehicle's operating system to adjust the headrest body 1 up and down and / or front and back.
[0036] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application.
