[0024] The embodiments of the present utility model are described in detail below.

[0025] Embodiment 1

[0026] Depend on Figure 1-5 Provided is an anti-shake automobile rearview mirror, comprising a rearview mirror 1 and a frame 2, a shock-absorbing component installed in the frame 2, and a connecting component arranged between the frame 2 and a vehicle body.

[0027] The shock-absorbing block 4 is fixedly connected to the back of the rearview mirror 1, an installation cavity 201 is opened in the frame 2, a rubber pad 401 is arranged in the installation cavity 201 to abut against the side of the shock-absorbing block 4, a spring 402 and a damper 403 are arranged between the rubber pad 401 and the installation cavity 201, and the two ends of the spring 402 and the damper 403 are respectively fixedly connected to the installation cavity 201 and the rubber pad 401, so that the outer structure of the rearview mirror 1 is not damaged. If the rearview mirror 1 shakes, its shaking will be transmitted to the spring 402 through the rubber pad 401, and the spring 402 will absorb and transform the vibration force to play a buffering role. The damper 403 will increase the loss of the vibration force in the process of the spring 402 absorbing and transforming the vibration force, thereby achieving a shock-absorbing effect on the rearview mirror 1, and then achieving anti-shake of the rearview mirror 1.

[0028] Furthermore, by setting the shock-absorbing block 4 to be a hexagon, the three longer sides of the shock-absorbing block 4 are respectively set horizontally, inclined and vertically, and the three rubber pads 401 are respectively adapted to and abutted against the three longer sides of the shock-absorbing block 4, so that the three rubber pads 401 can abut against the rearview mirror 1 from three different directions of the rearview mirror 1, thereby achieving shock absorption in three directions of the rearview mirror 1. While ensuring the all-round shock absorption effect, the setting of the rubber pads 401 is reduced as much as possible, saving the production cost.

[0029] Furthermore, a plurality of corresponding numbers of springs 402 and dampers 403 are arranged according to the length of the rubber pad 401, and one spring 402 and damper 403 are divided into a group, and multiple groups are arranged in a linear array with equal intervals between the rubber pad 401 and the installation cavity 201, so that when the spring 402 absorbs and transforms the vibration force transmitted from the rubber pad 401 through the rearview mirror 1, the vibration force is evenly absorbed and transformed from multiple positions on the rubber pad 401, so that the shock absorption process of the rubber pad 401 is more stable, and the springs 402 in each group are arranged around the outer wall of the damper 403, so that the occupied space of the rubber pad 401 and the spring 402 partially overlap, so that more groups of rubber pads 401 and springs 402 can be arranged between the rubber pad 401 and the installation cavity 201, thereby improving the shock absorption effect of the rubber pad 401.

[0030] Specifically, the connection assembly is divided into a connection component and a fixing component.

[0031] The connecting parts include a connecting rod 202 fixedly connected to the shortest side of the frame 2 and a connecting block 3 fixedly connected to the side of the vehicle body. A spherical docking block 203 is fixedly connected to the other end of the connecting rod 202, and a spherical docking groove 301 slightly larger than the docking block 203 is opened on the connecting block 3, so that the docking block 203 is connected in the docking groove 301 with damping rotation, so that the relative position of the frame 2 and the vehicle body can be adjusted by freely rotating by holding the frame 2, so as to adapt to the different rear-view requirements of different heights and vehicle lengths, thereby improving the versatility of the rearview mirror 1.

[0032] The fixing component includes a spherical iron block 204 which is slightly smaller than the docking block 203 and is installed in the docking block 203. An electromagnet 302 is installed in the docking groove 301. A wiring cavity 303 is opened on the connecting block 3, and its two ends are respectively connected to the back of the electromagnet 302 and the inside of the vehicle body, so that the electromagnet 302 can be connected to a power source through the wiring cavity 303. By starting the power source, the electromagnet 302 obtains magnetic force, and then the iron block 204 is adsorbed and fixed by magnetic force, so that when the car is driving at high speed and traveling on a bumpy road, the position of the frame 2 is more stable, thereby improving the stability of the device.

[0033] Optionally, as another embodiment of the present invention, the docking block 203 is made of a material with a rough surface and a hollow interior and high magnetic permeability, such as iron, and the electromagnet 302 is in direct contact with the docking block 203 .

[0034] By adopting the above design, the electromagnet 302 can directly contact the docking block 203 after being energized without any obstruction, and has a higher magnetic permeability and a stronger adsorption force.

[0035] Working principle:

[0036] When in use, first dock the connecting block 3 with the vehicle body by means of fastening methods such as screws or welding, then connect the power supply to the electromagnet 302 through the wiring cavity 303, hold the frame 2 to rotate the docking block 203 to adjust the position of the frame 2 until the rear of the vehicle is visible, then start the power supply to power the electromagnet 302, so that the electromagnet 302 obtains magnetic force to adsorb and fix the iron block 204, thereby completing the installation and fixation of the device.

[0037] If the vehicle is traveling at high speed or on a bumpy road, when the rearview mirror 1 is bumped and vibrates, the vibration will be transmitted to the spring 402 through the rubber pad 401. The spring 402 will absorb and transform the vibration force to play a buffering role. The damper 403 will increase the loss of vibration force in the process of the spring 402 absorbing and transforming the vibration force, thereby achieving a shock-absorbing effect on the rearview mirror 1 and further achieving anti-shake of the rearview mirror 1.

[0038] 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.
