[0024] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-5As shown, the utility model provides a technical solution: a car switch button noise reduction device, comprising a base tube 1, a button 2 movably connected to the top of the base tube 1, a connecting rod 3 fixedly connected to the inner bottom of the button 2, a moving block 4 fixedly connected to the outer side of the connecting rod 3, a retarding mechanism 5 is provided on the inner side of the base tube 1, and the retarding mechanism 5 is movably connected to the moving block 4, a guide column 6 is fixedly connected to the inner side of the base tube 1, the guide column 6 is sleeved on the outer side of the connecting rod 3, a connecting mechanism 7 is provided on the inner side of the guide column 6, and the connecting mechanism 7 conflicts with the bottom of the connecting rod 3, a limiting mechanism 8 is provided on the inner side of the base tube 1, and the connecting mechanism 7 is connected to the limiting mechanism 8.

[0026] like Figure 1 and Figure 2 As shown, the deceleration mechanism 5 includes a return spring 501 and a deceleration bar 502, and the return spring 501 and the deceleration bar 502 are distributed in a circular array. The return spring 501 is arc-shaped, one end of the return spring 501 is fixedly connected to the back side of the deceleration bar 502, and the other end of the return spring 501 is fixedly connected to the inner side of the base tube 1. Several guide grooves 9 are provided on the outer side of the guide column 6, and the deceleration bar 502 is movably connected to the inner side of the guide groove 9 through a rotating shaft, and the outer side of the moving block 4 is in conflict with the front side of the deceleration bar 502.

[0027] When the connecting rod 3 moves upward, it drives the moving block 4 to move downward synchronously on the inner side of the guide column 6. At this time, the outer side of the moving block 4 conflicts with the inner side of the slow-moving bar 502. Under the action of the reset spring 501, the reset of the connecting block is not completed in a short time, reducing the impact sound of the button 2 and other components, thereby improving the noise reduction effect of the switch button 2.

[0028] like Figure 1 and Figure 3 As shown, the connecting mechanism 7 includes a connecting rod 701, a control block 702 and a compression spring 703. The control block 702 passes through the guide column 6 and is movably connected to the guide column 6 through the guide groove 9. The connecting rod 701 passes through the center of the control block 702 and is movably connected to the control block 702. The compression spring 703 is sleeved on the outside of the connecting rod 701. One end of the compression spring 703 is fixedly connected to the bottom end of the control block 702, and the bottom end of the compression spring 703 is fixedly connected to the bottom of the base cylinder 1. The connecting rod 701 passes through the bottom of the base cylinder 1 and is movably connected to the base cylinder 1. The top of the connecting rod 701 conflicts with the bottom end of the connecting rod 3.

[0029] The compression spring 703 helps to reset the control block 702, pushing the connecting rod 3 to move inside the guide column 6, and using the force of the compression spring 703 to restore the deformation, driving the moving block 4 to push the slow-moving bar 502 to the inside of the guide groove 9.

[0030] like Figure 1、 Figure 4 and Figure 5 As shown, the limiting mechanism 8 includes a sleeve 1 801, a fixed block 802 and a limiting block 803. The fixed block 802 and the limiting block 803 are symmetrically arranged with the axis center of the sleeve 1 801 as the origin. The limiting block 803 is fixedly connected to the outer side of the sleeve 1 801, the fixed block 802 is fixedly connected to the bottom end of the base tube 1, and the limiting blocks 803 are respectively in conflict with the fixed blocks 802. The bottom end of the sleeve 1 801 is movably connected to the bottom end of the base tube 1, and the bottom end of the control block 702 is fixedly connected to the sleeve 2 10. A group of symmetrical control pins 11 are fixedly connected to the outer side of the bottom end of the sleeve 2 10. A group of control grooves 12 are opened on the inner side of the sleeve 2 10. The control grooves 12 are all in a broken line shape, and the control pins 11 are respectively movably connected to the control grooves 12. The outer side of the sleeve 2 10 is movably connected to the inner side of the sleeve 1 801.

[0031] Through the broken line design of the control groove 12, when the control pin 11 is located at the middle inflection point of the control groove 12, the limit block 803 conflicts with the fixed block 802, reducing the rebound operation of the button 2 after being pressed, optimizing the noise caused by the rebound of the button 2, and further improving the degree of noise optimization, thereby optimizing the operating logic of the button 2, and the button 2 is arranged on the outside of the base tube 1 to form an enclosing structure, thereby reducing the transmission of sound inside the base tube 1.

[0032] Working principle: When in use, press the button 2 downward, driving the connecting rod 3 to move downward on the inner side of the guide column 6, so that the moving block 4 moves downward synchronously. At this time, the connecting rod 3 contacts the connecting rod 701 and moves downward synchronously, causing the compression spring 703 to shorten, driving the control block 702 to move downward synchronously along the guide column 6, so that the sleeve 1 801 moves toward the inner side of the sleeve 2 10, and gradually controls the pin 11 to move to the inside of the control groove 12. At this time, the control pin 11 is in the middle position of the control groove 12. At this time, the bottom end of the connecting rod 701 is connected to the internal electronic components of the car, and the connecting rod 701 is fixed. Since the control pin 11 can only move downward and cannot rotate, the sleeve 2 10 can rotate. Therefore, under the action of the control pin 11 and the control groove 12, the sleeve 2 10 drives the limit block 803 to rotate, and the fixed block 802 has a certain elasticity, and the limit block 803 contacts the fixed block 802 respectively. After the cam 703 is released, the control pin 11 moves downwards and moves upwards, and the control pin 11 moves upwards from the bottom of the control slot 12. At this time, the compression spring 703 cannot bounce the control block 702. Only when the button 2 is continued to be pressed downwards, the control pin 11 continues to move downwards until it moves to the bottom of the control slot 12. At this time, the connecting rod 701 moves downwards, and the car releases the position limit of the connecting rod 701. The control block 702 is pushed upwards by the compression spring 703, so that the control pin 11 moves upwards from the bottom of the control slot 12. Due to the large upward force of the compression spring 703, the limit block 803 cannot be squeezed by the fixed block 802, that is, the sleeve 10 is reset after one reciprocating rotation. After the connecting rod 701 pushes the connecting rod 3 upwards, the moving block 4 conflicts with the slow-moving bar 502, pushing the slow-moving bar 502 to flip outward. Under the action of the reset spring 501, the moving speed of the moving block 4 is limited, so that the button 2 slowly resets, and the slow-moving bar 502 is finally received into the inside of the guide slot 9.
