[0032] The locking assembly 6 is installed in the car seat. When the device needs to be installed, it is only necessary to align the mounting column 404 with the hole on the seat and insert it to achieve preliminary installation. At this time, the user can take his hands off the device, and then press the pressing head 601 downward, so that the connecting rod 604 pulls the locking block 605, so that the locking block 605 loses its cover on the mounting column 404, and the device can fall by gravity. When disassembling the device, it only needs to be pulled upward to be directly disassembled.

[0033] like Figure 3 As shown, the headrest assembly 1 includes a headrest shell 101, a soft cover 102 and a head outer bag 103, and the soft cover 102 is arranged outside the headrest shell 101, and the head outer bag 103 is arranged outside the soft cover 102;

[0034] The space between the head outer capsule 103 and the soft sleeve 102 is filled with liquid, and the fluidity of the liquid makes it easier for the head to be reset when it leaves the head outer capsule 103 .

[0037] like Figure 1 and Figure 2 As shown, an audio installation structure for easily disassembling a car headrest includes an edge-sealing installation component 2 and the above-mentioned easily disassembling car headrest. The edge-sealing installation component 2 is installed on the left and right sides of the headrest component 1.

[0038] like Figure 2 As shown, the edge sealing installation assembly 2 includes a mounting plate 201 and a protective net 202 , and the protective net 202 is provided on a side of the mounting plate 201 away from the headrest assembly 1 .

[0039] like Figure 1 , Figure 2 , Figure 4 ,like Figure 6 , Figure 7 , Fig. 9 and Fig.10 The sealing assembly 3 is installed in the middle of one side of the mounting plate 201 close to the central axis of the headrest assembly 1, and the pneumatic linkage assembly 7 is installed at the front end of the side of the mounting plate 201 close to the central axis of the headrest assembly 1, the sound receiving assembly 8 is installed at the rear end of the pneumatic linkage assembly 7, and the connecting assembly 5 is installed at the upper end of the locking assembly 6.

[0040] like Figure 4 As shown, the sealing assembly 3 includes a lifting plate 301, a sealing plate 302, a first spring 303, a first telescopic rod 304 and a fixed plate 305, and the sealing plate 302 is connected to the side of the lifting plate 301 close to the edge sealing installation assembly 2, the first spring 303 is connected to the middle of the side of the lifting plate 301 away from the horizontal center line of the edge sealing installation assembly 2, and the first telescopic rod 304 is connected to the front and rear ends of the side of the lifting plate 301 away from the horizontal center line of the edge sealing installation assembly 2, and the fixed plate 305 is connected to the side of the first telescopic rod 304 away from the lifting plate 301;

[0041] After the playback speaker 401 is retracted, the sealing plate 302 blocks the mounting plate 201 by relying on the elastic structure formed between the lifting plate 301 through the first spring 303 and the first telescopic rod 304 and the fixing plate 305, so that it is easier to collect all the sounds emitted by the playback speaker 401 into the headrest shell 101 to reduce leakage.

[0042] like Figure 7 As shown, the connection assembly 5 includes an inner mounting frame 501, a guide groove 502, a push plate 503, a power supply electrode 504 and a second spring 505, and the guide groove 502 is installed at the lower end of the inner mounting frame 501, the push plate 503 is connected to the upper end of the inner mounting frame 501, and the front end of the push plate 503 is connected to the power supply electrode 504, and the rear end of the push plate 503 is connected to the second spring 505;

[0043] The conductive copper strip 403 contacts and forms a connection with the power supply electrode 504, thereby supplying power to the device and ensuring the operation of the device. This connection method can also facilitate the disassembly and assembly of the device. During the disassembly and assembly process, the staff does not need to be disturbed by the connecting wire, which makes it easier to carry out the disassembly and assembly work. The push plate 503 can be pushed by the second spring 505, so that the power supply electrode 504 is in close contact with the conductive copper strip 403, which is conducive to the stability of current transmission.

[0044] like Fig. 9As shown, the pneumatic linkage assembly 7 includes an air box 701, a piston plate 702, a push block 703, an air pipe 704, a sleeve rod 705, a movable piston 706 and a mounting rod 707, and the piston plate 702 is installed inside the air box 701, the front end of the piston plate 702 is connected to the push block 703, and the rear end of the air box 701 is connected to the air pipe 704, the end of the air pipe 704 away from the air box 701 is connected to the sleeve rod 705, and the movable piston 706 is installed inside the sleeve rod 705, and one side of the movable piston 706 is connected to the mounting rod 707;

[0045] When the user's head rests on the head outer bag 103, the push block 703 is pushed, thereby moving the piston plate 702, squeezing the gas inside the air box 701 from the air pipe 704 into the sleeve rod 705, thereby moving the movable piston 706 and driving the installation rod 707 to move.

[0046] like Fig.10 As shown, the sound receiving assembly 8 includes a sound transmission block 801, a sound transmission horizontal rod 802, a sound transmission vertical rod 803, a mounting head 804, an elastic block 805, a sound receiving ring 806 and a sound receiving membrane 807, and the rear end of the sound transmission block 801 is connected to the sound transmission horizontal rod 802, the lower part of the rear end of the sound transmission horizontal rod 802 is connected to the sound transmission vertical rod 803, and the lower end of the sound transmission vertical rod 803 is connected to the mounting head 804, the outer side of the mounting head 804 is connected to the elastic block 805, and the inner side of the mounting head 804 is connected to the sound receiving ring 806, and the inner side of the sound receiving ring 806 is connected to the sound receiving membrane 807;

[0047] When the playback speaker 401 is pulled into the headrest shell 101, relying on the elasticity of the elastic block 805, the rotating structure between the sound receiving ring 806 and the mounting head 804 is driven to rotate, so that the sound receiving ring 806 blocks the sound outlet of the playback speaker 401, and then the vibration emitted by the speaker is collected by the sound receiving membrane 807, and then transmitted to the headrest shell 101 through the sound transmission vertical rod 803, the sound transmission horizontal rod 802 and the sound transmission block 801.

[0048] Working principle: First, install the connecting component 5 and the locking component 6 into the seat, wherein the power supply electrode 504 will be connected to the circuit in the seat, and the pressing head 601 will leak out of the seat, and then align the mounting column 404 with the hole on the seat, so as to insert the mounting column 404 into the seat to install the device, and then press the pressing head 601 to make the pressing frame 602 drive the connecting block 603 to descend, so that the connecting rod 604 is tilted, and the locking block 605 is pulled toward the middle, so that the locking block 605 no longer blocks the mounting column 404, so that the device can fall by gravity, thereby adjusting the head outer bag 103 to the specified height, and then release the pressing head 601, relying on the locking block 605 and the second telescopic rod 606 and the third spring 607. The elastic structure formed by the locking block 605 pops out, so that the locking block 605 is stuck on the mounting column 404, thereby fixing the device. The guide groove 502 can limit the locking block 605, which is convenient for the movement of the locking block 605. During the operation of the device, the power supply electrode 504 is connected to the conductive copper strip 403 for power supply, and then the power is transmitted to the playback speaker 401 through the connecting wire 402, so that the playback speaker 401 can work normally. When the device is working, the mounting plate 201 can be embedded and fixed to the playback speaker 401, and the protective net 202 can shield and protect the playback speaker 401, thereby preventing dust and the like from damaging the playback speaker 401. The lifting plate 301 relies on the elastic structure formed between the first spring 303 and the first telescopic rod 304 and the fixing plate 305. The performance can pressurize the playback speaker 401 to form a limit installation, so that the device can work normally. When the device is finished working, if the user leans his head on the head outer bag 103, the pushing block 703 will be pushed, so that the piston plate 702 moves, and the gas inside the air box 701 is squeezed from the air pipe 704 into the sleeve rod 705, so that the movable piston 706 moves, and drives the installation rod 707 to move, so as to pull the playback speaker 401 into the headrest shell 101. When the playback speaker 401 is pulled into the headrest shell 101, relying on the elasticity of the elastic block 805, the rotating structure between the sound receiving ring 806 and the installation head 804 is driven to rotate, so that the sound receiving ring 806 blocks the sound outlet of the playback speaker 401, and then the sound is received through the sound receiving membrane 807. The vibration emitted is collected and then transmitted to the headrest shell 101 through the sound transmission vertical rod 803, the sound transmission horizontal rod 802 and the sound transmission block 801, so that bone conduction can be achieved for the user's head and the texture of the sound can be increased. After the playback speaker 401 shrinks, the elastic structure formed by the lifting plate 301 through the first spring 303 and the first telescopic rod 304 and the fixing plate 305 makes the sealing plate 302 block the mounting plate 201, so that it is easier to collect all the sounds emitted by the playback speaker 401 into the headrest shell 101 to reduce leakage, which is easier for the sound transmission block 801 to transmit the sound. The space between the head outer capsule 103 and the soft cover 102 is filled with liquid, and the fluidity of the liquid makes it easier for the head to reset when it leaves the head outer capsule 103.In this way, the opening of the mounting plate 201 that pushes out the playing speaker 401 can be re-operated, so that the user can hear the sound clearly even if the head is away from the head bag 103.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
