[0021] A screen 6 is installed inside the headrest liner 3, a PCBA sub-board 11 is fixedly installed inside the upper shell 2, a power button 9 is fixedly installed on the outside of the PCBA sub-board 11, and one end of the power button 9 passes through the inside of the translucent cover 1 and the upper shell 2, a MIC 10 is fixedly installed on the outside of the PCBA sub-board 11, and one end of the MIC 10 passes through the inside of the translucent cover 1 and the upper shell 2, a curved mirror 5 is fixedly installed inside the headrest liner 3, and a transparent beam splitter 16 is fixedly installed inside the translucent cover 1.

[0022] Before using the headrest 12, the staff needs to assemble the headrest 12. First, use the adhesive to tightly fit the translucent cover 1 on the upper shell 2, fix the power button 9 and MIC10 on the outside of the PCBA sub-board 11, and pass the MIC10 and power button 9 through the translucent cover 1 and the inside of the upper shell 2 through the PCBA sub-board 11. Then, hold the curved mirror 5, screen 6 and main board 8 accurately on the headrest liner 3, install the shaft 4 on the surface of the upper shell 2, and fix the headrest internal skeleton 7 and the headrest 12 with the adhesive. After installing the screen 6, watch the screen 6 with your eyes, which is refracted into an image by the curved mirror 5. Drive the shaft 4 to rotate through the upper shell 2, so that the angle of the screen 6 can be easily adjusted, thereby completing the assembly of the headrest 12.

[0023] Before using the headrest 12, it is necessary to assemble the headrest 12. First, use the adhesive to tightly fit the translucent cover 1 on the upper shell 2. Then, fix the power button 9 and MIC10 on the outside of the PCBA sub-board 11. Pass the MIC10 and power button 9 through the translucent cover 1 and the inside of the upper shell 2 through the PCBA sub-board 11. Then, hold the curved mirror 5, screen 6 and main board 8 accurately on the headrest liner 3. Install the shaft 4 on the surface of the upper shell 2. Then, fix the headrest internal frame 7 and the headrest 12 with the adhesive. After installing the screen 6, compared with traditional devices, this device facilitates the assembly of the fixed headrest 12 through the adhesive. The assembly process demonstrates a high degree of craftsmanship and humanized design. The ingenious combination of the translucent cover 1 and the curved mirror not only ensures the precise transmission and clear imaging of the image light, but also gives the viewer an unprecedented immersive visual enjoyment. In addition, the power button 9 and MI The convenient layout of C10 and the free adjustment function of the screen at 6 angles greatly improve the convenience and comfort of use. The entire assembly process is meticulous, ensuring the stability and durability of the headrest 12, bringing users a more secure and enjoyable user experience.

[0024] The upper shell 2 , the headrest 12 and the headrest internal frame 7 are internally threaded with bolts 13 , and the bolts 13 are internally shaped like a cross.

[0025] Hold the bolt 13 by hand and place it inside the headrest 12. Now take the screw and place it inside the headrest 12. Slowly screw the bolt 13 into the headrest internal frame 7, the headrest 12 and the upper shell 2. Fix the headrest 12, the headrest internal frame 7 and the upper shell 2 with the bolt 13, ensuring the stability of the headrest internal frame 7, the headrest 12 and the upper shell 2 during use and improving the use efficiency of the upper shell 2.

[0026] A support rod 14 is fixedly mounted on the bottom of the headrest internal frame 7, and the support rods 14 are of two identical sizes.

[0027] Since the support rods 14 are in two shapes of the same size at the bottom of the internal frame 7 of the headrest, it is convenient to insert the internal frame 7 of the headrest into the vehicle backrest with the support rods 14, thereby ensuring the stability of the internal frame 7 and the headrest 12 during use and improving the utilization efficiency of the screen 6.

[0028] A Type-C interface 15 is fixedly installed on the outer side of the PCBA sub-board 11 , and the Type-C interface 15 runs through the interior of the translucent cover 1 and the upper shell 2 .

[0029] Since the Type-C interface 15 runs through the interior of the translucent cover 1 and the upper shell 2, the charging efficiency and compatibility are improved by adding the Type-C interface 15. It supports high-power transmission and realizes fast charging of mobile devices such as mobile phones and tablets. It is especially suitable for scenarios where it is frequently used during long-distance travel, and effectively avoids the impact of battery anxiety on the journey. At the same time, with the popularization of the Type-C interface 15, this design of the vehicle headrest can be widely adapted to various mobile devices, meet diverse charging needs, and provide passengers with a more convenient and efficient charging experience.

[0030] The working principle and use process of this utility model:

[0031] Before using the headrest 12, the staff needs to assemble the headrest 12. First, use the adhesive to tightly fit the translucent cover 1 on the upper shell 2. Then fix the power button 9 and MIC 10 on the outside of the PCBA sub-board 11. C10 and the power button 9 pass through the translucent cover 1 and the interior of the upper shell 2. Next, by grasping the curved mirror 5, the screen 6, and the mainboard 8 are precisely fixed to the headrest liner 3. The hinge 4 is installed on the surface of the upper shell 2. The headrest's internal frame 7 and the headrest 12 are fixedly connected using adhesive. After installing the screen 6, the power button 9 is pressed to turn on the screen 6. With the screen 6 serving as the source of the image, the generated image light is first projected onto a carefully designed translucent cover 1. This translucent cover 1 cleverly reflects this light onto a carefully crafted curved mirror 5. With its unique shape and angle, the curved mirror 5 precisely guides and transmits the image light to the area directly in front of the headrest 12 device. Ultimately, the viewer can easily and clearly see the vivid image that has undergone this series of optical processing, providing an immersive visual experience. The hinge 4 is driven by the upper shell 2 to rotate, allowing the angle of the screen 6 to be easily adjusted, thus completing the assembly of the headrest 12.

[0032] The imaging implementation principle is as follows: the light field engine screen 6 serves as the core display image source, and the light it emits is distributed through a precise transparent beam splitter 16. During this process, the transparent beam splitter 16 cleverly directs part of the light to the curved mirror 5, while the other part is allowed to pass through as stray light without interference. The focus is on the part of the light that is successfully transmitted to the curved mirror 5. After being precisely reflected by the curved mirror 5, it passes through the transparent beam splitter 16 again and finally converges at a position suitable for human viewing, presenting a clear and vivid image to the observer.
