DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 5 As shown, it is the first embodiment of the present invention, which provides a low-frequency vibration vehicle audio system, the device comprises a housing assembly 1, an abutment assembly 2 arranged on the outer surface of the housing assembly 1, the housing assembly 1 is provided with a shell 101, a speaker 102 is installed on the inner wall of the shell 101, positioning blocks 103 are installed on both sides of the outer wall of the shell 101, and the positioning blocks 103 are used to locate the installation position of the housing assembly 1 to avoid position rotation during use and improve the stability of use;

[0035] The abutment assembly 2 is provided with four arc-shaped members 202 located on the outer side of the housing 101, an arc-shaped groove 201 is provided in the housing 101, the inner wall of the arc-shaped groove 201 is movably connected with the four arc-shaped members 202, a connecting column 203 is installed at the bottom of the arc-shaped member 202, the bottom of the connecting column 203 extends into the arc-shaped groove 201 and the housing 101 and is installed with a disc 204, a mounting block 205 is connected to the outer side of the disc 204, the outer surface of the mounting block 205 is sleeved with the inner wall of the housing 101, a limiting ring 206 is sleeved on the inner wall of the mounting block 205, the outer side of the limiting ring 206 is connected with the inner wall of the housing 101, a spring 207 is sleeved on the outer surface of the limiting ring 206, the mounting block 205 is elastically connected with the housing 101 through the spring 207, and an inclined groove 208 is provided inside the disc 204;

[0036] When the fixing of the disc 204 is released, since the spring 1 207 is in a stretched state, a backward pulling force will be applied to the mounting block 205, driving the mounting block 205 to move on the outer surface of the limiting ring 206 to a suitable position. At the same time, the mounting block 205 will drive the disc 204, the connecting column 203 and the arc-shaped member 202 to move, and as the arc-shaped member 202 moves, the arc-shaped member 202 is driven to present an arch shape, and then the outer walls of the four arc-shaped members 202 support the car audio mounting slot to prevent it from moving in position;

[0037] The stabilizing component 5 is arranged on the back of the abutting component 2. The stabilizing component 5 supports the housing component 1 through four groups of support frames 502 arranged at equal intervals. The stabilizing component 5 includes an inclined plate 501. The outer wall of the inclined plate 501 is sleeved with the inner wall of the housing 101. The outer surface of the inclined plate 501 is connected to the outer wall of the disc 204. The inner wall of the support frame 502 is sleeved with the outer surface of the inclined plate 501. The support frame 502 extends to the outside of the housing 101. The end of the support frame 502 is a rubber block. The support frame 502 is elastically connected to the housing 101 through a spring.

[0038] As the disc 204 rotates, the disc 204 drives the inclined plate 501 to move, so that the extrusion support frame 502 moves outward. As the housing assembly 1 is installed into the audio installation slot, the support frame 502 will be unfolded from the inside of the door frame, so that the rubber block at its end is tightly attached to the inner wall of the inner cavity of the frame, and the housing assembly 1 is clamped inside the door frame to prevent it from moving out of the frame. At the same time, the rubber block installed at the end has a buffering effect when the housing assembly 1 moves forward and backward, thereby increasing its service life.

[0039] Therefore, during installation, the operator can clamp and install the installation slots of different sizes through the deformation of the four arc-shaped members 202, thereby improving the installation stability of the housing assembly 1;

[0040] Example 2

[0041] like Figures 5 to 9 As shown, this embodiment includes all the features of the embodiment 1, and the distinguishing technical feature is that the trigger mechanism 3 is arranged on the inner side of the abutment assembly 2, and the trigger mechanism 3 is provided with a movable disk 301, the outer surface of the movable disk 301 is sleeved with the inner wall of the housing 101, and the inner cavity of the movable disk 301 is sleeved with a pressing block 302, the outer side of the pressing block 302 extends into the inner cavity of the mounting block 205, and the inner side of the pressing block 302 is connected to a pressing rod 303, and the inner side of the pressing rod 303 extends to the outside of the movable disk 301, and the pressing rod 303 is connected to the inner side of the movable disk 301. The outer surface of the rod 303 is sleeved with a second spring 304, and the second spring 304 is elastically connected to the movable disk 301 through the pressure block 302. The inner wall of the housing 101 is connected to a fixed column 305, and the outer surface of the fixed column 305 is sleeved with a connecting plate 306. The outer surface of the connecting plate 306 contacts the end of the pressure rod 303. The interior of the housing 101 is provided with a card slot 308 located on both sides of the movable disk 301, and both sides of the movable disk 301 are provided with a ratchet 307 located inside the card slot 308;

[0042] The elastic force of the spring 1 207 drives the disc 204 and the mounting block 205 to move, and then the mounting block 205 drives the pressing block 302 and the movable disc 301 to move, and the inclined slot 208 is moved to the outside of the positive inclined block 403;

[0043] By setting the housing assembly 1, the vibration generated by its own low frequency, the shaking of the car when driving and the violent collision when closing the door are continuously damped by the arc-shaped member 202 and the spring 1 207.

[0044] Since the spring 1 207 will become fatigued after long-term use, the connection between the arc-shaped member 202 and the speaker will be unstable. After a period of use, the spring 1 207 will become elastically fatigued, and the deformed arc-shaped member 202 will gradually return to its original position, thereby driving the mounting block 205 to move back, so as to squeeze the pressing block 302. Due to the design of the pawl 307 and the slot 308, the movable disk 301 cannot be driven to return to its original position, so that the pressing block 302 is squeezed into the movable disk 301, and then the pressing block 302 drives the pressure rod 303 to move downward, squeezing the connecting plate 306, thereby triggering the impact structure 4 through the connecting plate 306. The impact of the impact structure 4 strengthens the deformation amplitude and elastic strength of the arc-shaped member 202.

[0045] The impact structure 4 is provided with a slide groove 401, which is opened inside the housing 101 and located outside the trigger mechanism 3. The interior of the slide groove 401 is connected with a mounting rod 402, and the outer surface of the mounting rod 402 is sleeved with an inclined block 403, and the end of the inclined block 403 contacts the back of the disc 204. The ball 405 is arranged in the inner cavity of the slide groove 401. The interior of the slide groove 401 is movably connected with a mounting plate 406 located below the connecting plate 306, and the bottom of the mounting plate 406 is sleeved with the bottom of the connecting plate 306. An electromagnet 407 is installed on the top of the mounting plate 406, and the top of the electromagnet 407 extends to the bottom of the ball 405 for magnetic connection. The interior of the housing 101 is provided with an inclined opening 409 located outside the mounting block 205, and the interior of the inclined opening 409 is sleeved with a clamping block 408, and the outer side of the clamping block 408 is connected to the outer side of the mounting block 205.

[0046] When elastic fatigue occurs in spring 1 207, arc-shaped member 202 is driven to reset, and mounting block 205 is driven to squeeze pressing block 302, and mounting plate 406 and electromagnet 407 are driven to move downward through pressing rod 303 and connecting plate 306. As electromagnet 407 moves, the adsorption of ball 405 is released, causing it to be in an active state. As the car door is opened, ball 405 inside housing assembly 1 moves to the farthest point of inclined block 403 due to inertia. When the car door is closed, the inertia of ball 405 causes ball 405 to collide with inclined block 403, driving inclined block 403 to squeeze disc 204, and then inclined groove 208 drives disc 204 to move. At this time, the arch amplitude of arc-shaped member 202 increases, and then the arc-shaped member 202 is re-engaged. The inner wall of the audio installation groove is newly squeezed, and the pressing block 302 is driven to move back to the inner cavity of the installation block 205 by impacting the inclined block 403, so as to reset the trigger mechanism 3, and the movable disk 301 as a whole and the disk 204 are driven to move by the impact force, so that the clamping block 408 on the installation block 205 is moved to the next inclined opening 409, thereby strengthening the clamping effect of the arc-shaped member 202 and the audio installation groove, thereby preventing the elastic fatigue of the arc-shaped member 202 and the spring 207 caused by long-term use and affecting the shock-absorbing effect of the shell component 1 by strengthening the deformation degree of the arc-shaped member 202, and preventing the sound quality of the low-frequency vibration car audio from being affected by shaking. At the same time, the arc-shaped member 202 continuously reduces the shock of the shell component 1 to prevent the damage of the internal components caused by long-term vibration;

[0047] Example 3

[0048] like Fig.10 and Fig.11As shown, this embodiment includes all the technical features of the embodiment 1, and the distinguishing technical features are that a sealing structure 6 is provided on the front of the shell component 1, and the sealing structure 6 is fitted to the frame by installing the shell component 1, and the sealing structure 6 includes a movable block 601, the outer surface of the movable block 601 is sleeved with the inner wall of the shell 101, and a moving plate 602 located in the inner cavity of the shell component 1 is installed on the inner side of the movable block 601, and an air cushion 603 is connected to the bottom of the moving plate 602, and a sealing ring 604 located on the top of the movable block 601 is installed on the outer surface of the air cushion 603, and the inner side of the sealing ring 604 extends to the outside of the shell 101;

[0049] When the shell assembly 1 is installed in the door frame, the shell assembly 1 is buckled inside the audio installation groove on the frame, so that the movable block 601 is pressed against the outer wall of the frame, driving the movable block 601 to move to the inside of the shell 101, and then the movable block 601 drives the moving plate 602 to press the air cushion 603, pushing the sealing ring 604 on the air cushion 603 inward, so that the sealing ring 604 fits against the outer wall of the frame, so as to achieve a sealing effect, so as to prevent the inner cavity of the frame from leaking due to the audio. At the same time, because the sealing ring 604 has good elasticity, the shell assembly 1 has a good limiting effect, and also has a good buffering effect, thereby increasing the service life of the audio.

[0050] A positioning rod 605 is installed on the inner wall of the moving plate 602 . The inner side of the positioning rod 605 penetrates the outer shell 101 and extends to the hinge center of the arc-shaped member 202 and extends to the inside of the disc 204 .

[0051] When installing the housing assembly 1, insert the housing assembly 1 into the installation slot, the outer wall of the frame will squeeze the movable block 601, and then the movable plate 602 drives the positioning rod 605 to move backward, and the positioning rod 605 moves out from the inside of the disc 204, releasing the fixation of the disc 204, and the elastic force of the spring 1 207 drives the arc-shaped member 202 to install speakers of different sizes;

[0052] Therefore, it is convenient for the operator to squeeze the housing assembly 1 to drive the sealing ring 604 to seal it, and at the same time release the fixation of the disc 204 to facilitate its rapid installation. At the same time, the installation operation is simple and time-consuming.

[0053] The working principle and use process of the present invention:

[0054] First, when the operator is installing audio equipment of different specifications, the shell assembly 1 is inserted into the installation groove on the vehicle frame, and the position of the shell assembly 1 is located by the positioning block 103 and the installation groove, and then the shell assembly 1 is connected to the inner cavity of the door frame. The outer wall of the door frame abuts against the movable block 601, so that the moving plate 602 is driven to squeeze the air cushion 603. At the same time, the deformation of the air cushion 603 drives the sealing ring 604 to move inward, so that it fits tightly with the vehicle frame. As the moving plate 602 moves, the positioning rod 605 is driven to move out from the inside of the disc 204, so that it releases the fixation of the disc 204.

[0055] Under the elastic force of spring 1 207, mounting block 205 moves on the outer surface of limiting ring 206, so as to limit disc 204. At the same time, disc 204 drives connecting column 203 and one end of arc-shaped member 202 to move inside arc-shaped groove 201, so that arc-shaped member 202 is arched, and is squeezed on the inner wall of frame mounting groove, so as to clamp low-frequency vibration speakers of different sizes. Moreover, as mounting block 205 moves, it drives pressing block 302 in the inner cavity to move, so that pressing block 302 drives movable disc 301, and ratchet 307 does not block it. Because the movement of mounting block 205 drives clamping block 408 to move gradually to the inside of another inclined opening 409, it provides resistance for spring 1 207, so as to avoid excessive arch amplitude of arc-shaped member 202. At the same time, the rotation of disc 204 drives the inclined groove 208 moves to the outside of the inclined block 403, and then due to the elastic force of the spring three 404, the inclined block 403 is driven to fit with the inner wall of the inclined groove 208, and then the rotation of the disc 204 can also drive the inclined plate 501 to move, so that the support frame 502 installed inside the shell 101 is squeezed out from the inside, and the rubber block at the end of the support frame 502 is tightly fitted with the inner wall of the door frame, so that it supports the shell assembly 1 as a whole, so that it is convenient for operators to quickly install the shell assembly 1 through the clamping and support of the arc-shaped member 202 and the support frame 502, and the design of the arched arc-shaped member 202, the sealing ring 604 and the rubber block at the end of the support frame 502 can buffer the vibration generated by the driving of the car and the low frequency of the audio, so that it has a good buffering effect after installation, and the service life of the equipment is increased;

[0056] Subsequently, after the housing assembly 1 is installed, after long-term use, the spring 1 207 becomes elastically fatigued due to the driving of the car, the low-frequency vibration of the audio system, and the opening and closing of the door, which in turn causes the arc-shaped member 202 to have a reduced arch amplitude, making it impossible to fit with the inner wall of the frame mounting groove, which easily leads to unstable installation. Since the arc-shaped member 202 has a reduced arch amplitude due to elastic fatigue, it will drive the connecting column 203 to reset and move. In this solution, the connecting column 203 drives the disc 204 and the mounting block 205 to rotate, so that the installation The clamping block 408 on the mounting block 205 is moved out from the inside of the oblique opening 409 and resets backward. At the same time, the mounting block 205 is reset and rotated. Due to the design of the pawl 307 and the clamping groove 308, the movable disk 301 cannot be reset and moved. The mounting block 205 squeezes the pressing block 302, which drives the pressure rod 303 to squeeze the connecting plate 306. Then, the connecting plate 306 is pressed downward to drive the mounting plate 406 and the electromagnet 407. As the electromagnet 407 moves, the electromagnet 407 is driven to release the adsorption of the ball 405. The fixing of the ball 405 is released. Then, when the car door is opened, the ball 405 inside will move away from the inclined block 403 due to inertia. Then, when the car door is closed, the excessive inertia force will drive the ball 405 to hit the back of the inclined block 403. The extrusion force generated by the collision causes the driving disc 204 to move, thereby driving the block 408 on the mounting block 205 to move forward and be stuck in the inclined opening 409 of the front grid. Through the setting of the inclined opening 409, the block 408 is stuck inside to keep the arc The arc-shaped member 202 is limited, and the movement of the mounting block 205 will drive the clamping block 408 to move into the inner cavity, and drive the movable disk 301 forward a little, so as to strengthen the arch amplitude of the arc-shaped member 202, so that it can be clamped to the inner wall of the mounting groove again, and the electromagnet 407 can be moved by the resetting of the clamping block 408 to be adsorbed with the ball 405, so that when the spring 207 inside the shell assembly 1 appears elastic fatigue, the clamping effect of the arc-shaped member 202 is strengthened by the impact generated when the door is closed, thereby improving the stability.
