As shown in fig. 1 to 4, in the first embodiment, the vehicle access panel 100 is covered on an access opening 201 formed on a vehicle body 200, and the vehicle access panel 100 includes a panel body 10 and a vibration damping member 20. The board body 10 includes a first sub-board 11 and a second sub-board 12, the first sub-board 11 is connected with the vehicle body 200, the first sub-board 11 is connected around the second sub-board 12, and the vibration damper 20 is disposed on the first sub-board 11 and around the second sub-board 12.

In this application, the vehicle access cover 100 includes the plate body 10 and the damping piece 20, the damping piece 20 sets up on the first subplate 11 and encircle the second subplate 12, therefore, when the inside device of access produces vibration and makes automobile body 200 vibrates, the existence of damping piece 20 can make the vibration of vehicle access cover 100 weakens, and then makes with automobile body 200 vibration that vehicle access cover 100 is connected weakens to promote the riding comfort of personnel in the car.

In the second embodiment, the vibration damping member 20 includes a vibration damping rubber 22. Since the rubber material has elasticity and damping characteristics, it can convert the vibration energy into minute deformation and heat dissipation for many round trips to absorb and eliminate the vibration energy, and thus the rubber can provide noise isolation and vibration reduction effects, and further, the vibration reduction member 20 can also be a vibration reduction spring 21.

In the third embodiment, the vibration damping member 20 includes a vibration damping spring 21 and a vibration damping rubber 22. Since the damping effect of the damping spring 21 is better than that of the damping rubber 22, but the damping rubber 22 also has the function of noise isolation, the damping member 20 includes the damping spring 21 and the damping rubber 22, and the damping effect can be improved while the vehicle access cover plate 100 has the function of noise isolation, compared with the damping member 20 including the damping spring 21 or the damping rubber 22.

Thus, the first rubber ring 221 is abutted between the vehicle bodies 200 inside the access opening 201 of the first sub-board 11, and when the vehicle bodies 200 inside the access opening 201 vibrate due to vibration generated by an engine or the like, the first rubber ring 221 can attenuate the vibration of the first sub-board 11.

Compared with the arrangement in the form of rubber blocks (with a space between the blocks, for example, rubber rings are arranged at four corner positions of the first sub-board 11, wherein the shape of the first sub-board 11 is rectangular or quasi-rectangular), the vibration damping rubber 22 is arranged in the form of rubber rings, so that vibration damping can be performed on each position of the first sub-board 11, and the vibration damping effect is better.

In some embodiments, the damping rubber 22 further includes a second rubber ring 222, and the second rubber ring 222 is disposed at an outer edge of the second sub-board 12 and on a side of the first sub-board 11 facing the inside of the access opening 201.

Wherein, the first rubber ring 221 and the second rubber ring 222 are disposed at intervals.

In other embodiments, the damping rubber 22 may also be disposed on a side of the first sub-board 11 facing away from the interior of the access opening 201.

As shown in fig. 1, 4, 6 and 7, in other embodiments, the vibration damping rubber 22 is disposed on a side of the first sub-board 11 facing away from the interior of the access opening 201.

The first sub-board 11 includes a first annular step portion 111 and a second annular step portion 112, the first annular step portion 111 is connected with the second annular step portion 112, the first annular step portion 111 surrounds the second annular step portion 112, a surface of the second annular step portion 112 facing the inside of the access hole 201 and a surface of the first annular step portion 111 facing the inside of the access hole 201 are in the same plane, the height of the first annular step portion 111 is greater than that of the second annular step portion 112, the second sub-board 12 is arranged on a surface of the second annular step portion 112 facing away from the inside of the access hole 201 and surrounded by the first annular step portion 111, and the thickness of the second sub-board 12 plus the height of the second annular step portion 112 is equal to the height of the first annular step portion 111.

Wherein the vibration damping rubber 22 is disposed on the second annular step portion 112, and the vibration damping rubber 22 is disposed on a surface of the second annular step portion 112 facing the inside of the access opening 201, and/or on a surface of the second annular step portion 112 facing away from the inside of the access opening 201. When the vibration damping rubber 22 is disposed on the surface of the second annular step portion 112 facing away from the inside of the access hole 201, a first groove 1120 is formed on the surface of the second annular step portion 112 facing away from the inside of the access hole 201, a second groove 1121 is correspondingly formed on the surface of the second sub-board 12, which is close to the second annular step portion 112, and the vibration damping rubber 22 is disposed in the first groove 1120 and the second groove 1121, so that the tightness between the first sub-board 11 and the second sub-board 12 can be ensured, and vibration isolation can be achieved.

In some embodiments, the damping springs 21 are plural, and the damping springs 21 are disposed on a side of the first sub-board 11 facing the inside of the access opening 201, and are located between the first rubber ring 221 and the second rubber ring 222.

The vibration damping spring 21 is abutted between the first sub-board 11 and the vehicle body inside the access opening 201, so that when vibration is generated by a vibration device inside the access opening 201, the vibration damping spring 21 is elastically deformed, thereby reducing the vibration of the first sub-board 11, and when the vibration of the first sub-board 11 is reduced, the vibration of the second sub-board 12 connected to the first sub-board 11 and the vehicle body 200 are correspondingly reduced.

In some embodiments, the first sub-board 11 is rectangular or rectangular-like (for example, rectangular with rounded corners), and the damper springs 21 are disposed at four corner positions of the first sub-board 11. Wherein, the vibration damping springs 21 are four, and the vibration damping springs 21 are respectively arranged at four corners of the first sub-board 11.

In some embodiments, the damping springs 21 and the damping rubber 22 protrude from a surface of the second sub-board 12 facing the inner side of the access opening 201. This can prevent the second sub-panel 12 from directly contacting other vibration-conducting or vibration-generating objects than the first sub-panel 11, thereby enhancing the vibration-damping effect of the vehicle access panel 100.

As shown in fig. 4, in some embodiments, the surface of the second daughter board 12 is provided with ribs 120. Thereby, the strength of the second sub-board 12 is enhanced. Since the second sub-board 12 is not directly connected to the vehicle body 200 nor is it directly in contact with an instrument that generates vibration, enhancing the strength of the second sub-board 12 can reduce the vibration amplitude of the second sub-board 12.

In some embodiments, the reinforcing ribs 120 are disposed in a crossing manner, and the reinforcing ribs 120 have a plurality of triangular shapes and/or triangle-like shapes on the surface of the second daughter board 12.

Specifically, some of the reinforcing ribs 120 are disposed in parallel and extend in a first diagonal direction of the first sub-board 11; some of the reinforcing ribs 120 are disposed in parallel and extend in a second diagonal direction of the first sub-board 11; some of the ribs 120 extend parallel to a first side of the first sub-board 11 and some of the ribs 120 extend parallel to a second side of the first sub-board 11, the first side being in a crossing relationship with the second side.

In other embodiments, the reinforcing ribs 120 are disposed in a crossing manner, and the reinforcing ribs 120 form a plurality of quadrilaterals on the surface of the second sub-board 12.

The reinforcing ribs 120 are in a plurality of triangles and/or triangle-like shapes on the surface of the second sub-board 12, and compared with the reinforcing ribs 120, the reinforcing ribs 120 are in a plurality of quadrilaterals on the surface of the second sub-board 12, and the second sub-board 12 is more stable due to the stability of the triangle.
