Example

[0036] See also Figure 1-6 , a multi-stable modular vibration and noise reduction board, comprising a module unit 1 and a vibration and noise reduction unit 2, wherein the module unit 1 is installed at both ends of the vibration and noise reduction unit 2;

[0037] The vibration and noise reduction unit 2 comprises a support block 201 , a bistable spring 202 and a structural support 203 . The structural support 203 surrounds the outside of the support block 201 and the bistable spring 202 .

[0038] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The multi-stable modular vibration reduction and noise reduction plate of the present application is mainly composed of a module unit 1 and a vibration reduction and noise reduction unit 2, which are assembled by an elastic unit 3, wherein the module unit 1 is designed to be composed of an upper support plate 101 and a lower support plate 102, and the vibration reduction and noise reduction unit 2 is composed of a support block 201, a bistable spring 202 and a structural support 203, wherein the upper support plate 101 and the lower support plate 102 are designed to be equal in size, and the support block 201, the bistable spring 202 and the structural support 203 are integrally formed through an integrated molding technology, and the bistable spring 202 surrounds the outer periphery of the bistable spring 202, so that the support block 201 is located therein To improve the stability of the application, after molding, the module unit 1 and the vibration reduction and noise reduction unit 2 are snap-connected for easy disassembly and assembly. The X-shaped structural bracket 203 is designed to be used with the vibration reduction and noise reduction unit 2. It has a simple structure, is stable and reliable, has high human-computer interaction safety, and has low production cost. During the installation and layout process, it can also be customized according to actual needs to achieve the "vibration reduction and noise reduction" function, improve the human-computer environment, and promote the development of my country's national defense science. In addition, the vibration reduction and noise reduction unit 2 through the one-piece molding technology has the advantages of corrosion resistance and easy maintenance, and can be reused, which is of great significance to reducing production and maintenance costs.

[0040] In a specific implementation, first, in an initial state, the module unit 1 and the vibration reduction and noise reduction unit 2 in the multi-stable modular vibration reduction and noise reduction plate are both in a natural stable state.

[0041] Then, when the module unit 1 is subjected to vibration or noise, the upper support plate 101 or the lower support plate 102 contained therein will be displaced, thereby acting on the bistable spring 202 in the vibration reduction and noise reduction unit 2, causing it to deform and absorb energy.

[0042] When the multi-module unit 1 is subjected to large vibration and noise, the bistable spring 202 in the vibration and noise reduction unit 2 will become "instable" and jump, thereby absorbing more energy to achieve the function of vibration and noise reduction.

[0043] When the vibration or noise is eliminated, the initial state of the multi-stable modular vibration and noise reduction board can be achieved through human intervention.

[0044] It should also be noted that the present application sets up a first groove 4 and a second groove 401, wherein the first groove 4 is opened around the upper support plate 101 and the second groove 401 is opened around the lower support plate 102. Through the elastic unit 3, multiple groups of module units 1 can be assembled on the same horizontal plane to achieve customized installation.

[0045] Among them, the elastic unit 3 is designed as a special-shaped elastic rubber, so that the elastic unit 3 and the first groove 4 and the second groove 401 form a complementary relationship. At the same time, the elastic unit 3 is designed to be larger than the first groove 4 and the second groove 401, and has elasticity. When multiple groups of module units 1 are assembled on the same horizontal line, the elastic unit 3 is driven to be inserted into the first groove 4 or the second groove 401 accordingly, so that the elastic unit 3 and the inner walls of the first groove 4 and the second groove 401 are squeezed, which can increase the friction between the contact surfaces of the two and make the assembled connection more stable. The insertion end of the elastic unit 3 is designed with an arc, and the first groove 4 and the second groove 401 are provided with an arc to facilitate assembly.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
