For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] See also Figures 1 to 6 The utility model provides a technical solution: an entertainment-oriented car seat headrest structure using acoustic streaming technology, wherein the headrest body is composed of a headrest front cover 1, a headrest rear cover 2, a headrest rod guide column 5, a headrest rod guide sleeve 6, and a headrest foam 7, wherein the acoustic streaming mechanism 3 and the locking mechanism 4 are arranged inside the headrest.

[0032] See Figure 1 The sound flow mechanism 3 is arranged in the headrest back cover 2, and includes a sound guide port 31, a sound groove 32, a sound cover 33, a round head fixing screw 34, and a fastening hole 35; the sound groove 32 and the sound cover 33 are fixed by inserting the round head fixing screw 34 into the fastening hole 35 for placing the sound, wherein the fastening hole 35 is fixedly connected to the headrest back cover 2, and there are four sound grooves 32 inside the headrest for placing four groups of sound. The four sound grooves 32 are respectively distributed in the upper left, upper right, lower left and lower right directions of the headrest back cover 2, and are distributed in a matrix. The sound guide port 31 is connected to the inside of the sound groove 32, and the sound emitted by the sound is transmitted to the human ear through the sound guide port 31 to form a three-dimensional surround sound; in this way, the sound quality can be guaranteed to achieve lossless sound quality while realizing the function of supporting independent sound zones with directionality, which greatly enhances the comfort and personalized experience of the passengers.

[0033] See Figure 1The locking mechanism 4 includes a switch button 41, a connecting sheet metal 42, a locking groove 43, a spring piece 44, a limiting steel wire 45, a fastening long bolt 46, a cylindrical stop pin 47, and a return spring 48. The connecting sheet metal 42 connects the two headrest rod guide columns 5 to keep them parallel. When the headrest is adjusted in height, the switch button 41 is pressed, and the switch button 41 pushes the limiting steel wire 45 to push away the spring piece 44 to complete the unlocking of the locking groove 43. The headrest front cover mechanism 1 connected to the headrest rod guide column 5 moves up and down on the headrest rod guide column 5 through the headrest rod guide sleeve 6 to achieve the height adjustment of the headrest. The stroke of the headrest is 40 mm, which is determined by the slot length of the locking groove 43. When the height adjustment is completed, the spring piece 44 is pushed back, so that the limiting steel wire 45 is stuck in the slot of the locking groove 43, and the headrest is in a locked state. The return spring 48 can hook the limit wire 45. When the switch button 41 is pressed to unlock the locking mechanism 4, the switch button 41 pushes the limit wire 45 to complete the headrest height adjustment. At this time, the return spring 48 pulls the limit wire 45 back and the switch button 41 pops out so that the switch button 41 can be pressed next time.

[0034] See Figure 6 The headrest front cover 1 includes a guide post receiving groove 11 and a front cover connecting slot assembly 12; the guide post receiving groove 11 is located on one side of the headrest front cover 1, and the upper and lower sections of the headrest rod guide post 5 are fixed in the groove to prevent the headrest rod guide post 5 from shaking left and right. The guide post receiving groove 11 at the lower end is provided with a guide groove 1101. After the cylindrical stop pin 47 is inserted into the guide groove 1101, the headrest rod guide post 5 is completely positioned and fixed to the headrest front cover mechanism 1.

[0035] See Figure 1 The headrest rear cover 2 includes a switch inner shell 21 and a rear cover connecting slot assembly 22; the switch inner shell 21 is used to install the switch button 41, and the rear cover connecting slot assembly 22 and the front cover connecting slot assembly 12 are combined to form the headrest plastic shell, which is used to support the seat headrest and arrange internal mechanisms.

[0036] See Figure 6 The other side of the headrest front cover 1 is covered with foam 7, wherein one side of the headrest front cover 1 is fixed to the locking mechanism 4. After the headrest front cover 1 and the headrest rear cover 2 are assembled, the locking mechanism 4 fixed to one side of the headrest front cover 1 is fixed to the seat headrest frame 8 by fastening long bolts 46, thereby achieving the fixation of the headrest and the seat.

[0037] The working principle and usage process of this utility model are as follows: When the driver and passengers are seated, the headrest of this utility model can be activated through the vehicle system and electronic devices. Each headrest has four sound slots 32 inside, which can accommodate four sets of speakers. The four sound slots 32 are respectively located on the upper left, upper right, lower left, and lower right of the headrest back cover 2. Therefore, when the driver and passengers choose their favorite music to play, the sound flow mechanism 3 inside the headrest starts to work, and the sound guide port 31 is connected to the inside of the sound slot 32. The sound emitted by the speakers will be transmitted to the human ear through the sound guide port 31 to form a three-dimensional surround sound. Each passenger's headrest can play different music, which can not only ensure the quality of the sound and achieve lossless sound quality, but also realize the function of supporting independent sound zones with directionality, greatly enhancing the comfort and personalized experience of passengers. In the true sense, "movement" can increase driving pleasure, and "stillness" can deeply relax the body and mind!

[0038] When adjusting the headrest height, the switch button 41 is pressed, which pushes the limit wire 45, pushing it aside the spring plate 44 to unlock the locking slot 43. The headrest front cover 1, connected to the headrest rod guide post 5, moves up and down on the headrest rod guide post 5 via the headrest rod guide sleeve 6, thereby adjusting the headrest height. The headrest travel is 40 mm, determined by the length of the locking slot 43. When the height adjustment is completed, the spring plate 44 is pushed back, causing the limit wire 45 to engage in the locking slot 43, locking the headrest. The return spring 48 hooks onto the limit wire 45. When the switch button 41 is pressed to unlock the locking mechanism 4, the switch button 41 pushes the limit wire 45 to complete the headrest height adjustment. At this time, the return spring 48 pulls the limit wire 45 back, and the switch button 41 pops out, ready for the next press of the switch button 41.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
