[0004] However, it does not have the elastic buffering ability for the vibration of the generator. Only by separating the vibration source from the vehicle, the influence of vibration on the vehicle cannot be completely isolated, and the vibration force will still be transmitted to the vehicle frame through the device, and there will still be noise problems, and the ability to elastically buffer and decompose vibration cannot be achieved. Therefore, we need to upgrade and transform on the basis of the existing technology to overcome the problems and deficiencies it has. Content of the Utility Model

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 -4 shows, this embodiment provides a designed vehicle-mounted vibration isolation device, including a device body 1. The device body 1 contains a fixing plate 2, a generator 4, a buffer assembly 5 and an installation assembly 6. A movable plate 3 is arranged at the upper end of the fixing plate 2. The generator 4 is fixed on the movable plate 3. The buffer assembly 5 is installed below the fixing plate 2. The installation assembly 6 is arranged on the side of the movable plate 3.

[0025] Preferably, the buffer assembly 5 includes a base 51. A spring 52 is connected to the upper end of the base 51 and the top of the spring 52 is connected to an upper cover 53. A lower card seat 55 is arranged on the base 51. An upper card seat 56 is arranged at the lower end of the upper cover 53. A steel wire rope 57 is arranged between the lower card seat 55 and the upper card seat 56. Four groups of buffer assemblies 5 are provided. Installation grooves 59 are arranged on both sides of the base 51. The installation grooves 59 are of a linear structure. A connecting bolt 54 is arranged at the upper end of the upper cover 53. The connecting bolt 54 is fixed to the lower end of the fixing plate 2. A number of groups of steel wire ropes 57 are arranged and are connected in parallel in the lower card seat 55 and the upper card seat 56. Limiting sleeves 58 are respectively arranged at the upper end of the base 51 and the lower end of the upper cover 53. Both ends of the spring 52 are located within the limiting sleeves 58;

[0026] The upper cover 53 squeezes the spring 52, and the spring 52 buffers the upper cover 53, thereby realizing the elastic buffering of the movable plate 3 and the generator 4, avoiding the transmission of its vibration to the vehicle frame and inside the vehicle. The lower card seat 55 and the upper card seat 56 are elastically connected and buffered by the wire ropes 57 on both sides. When the upper cover 53 vibrates, it provides buffering and support on both sides, further improving the buffering capacity of the buffer assembly 5 and reducing the impact of vibration on the base 51.

[0027] Preferably, the installation assembly 6 includes side blocks 61. A gear 62 is movably arranged inside the side blocks 61. Rack bars 63 are engaged with both sides of the gear 62. An external knob 64 is arranged at the upper end of the gear 62. The side blocks 61 are fixed to the four sides of the movable plate 3. Limit holes 21 are arranged on the side of the fixed plate 2. The outer ends of the rack bars 63 penetrate through the side blocks 61 and are correspondingly inserted into the limit holes 21.

[0028] The movable plate 3 is docked on the fixed plate 2 through the side blocks 61. By controlling the rotation of the gear 62 through the external knob 64, the gear 62 drives the rack bars 63 to be inserted into or disengaged from the limit holes 21, which can realize the quick installation and disassembly of the movable plate 3, and thus facilitate the disassembly operation of the generator 4 without disassembling the lower fixed plate 2 and the buffer assembly 5, and the operation is simple and convenient.

[0029] The working principle and working process of the present utility model: When in use, first fixedly connect the generator 4 with the movable plate 3. The movable plate 3 is inserted into the fixed plate 2 through the side blocks 61. By controlling the rotation of the gear 62 through the external knob 64, the gear 62 drives the rack bars 63 to move outward and be inserted into the limit holes 21. Conversely, the operation can be used for disassembly, which is convenient for the overhaul and maintenance of the generator 4 without disassembling the bottom fixed plate 2 and the buffer assembly 5. When the generator 4 works, the vibration and pressure generated are transmitted to the fixed plate 2. The fixed plate 2 drives the upper cover 53 to move synchronously. The upper cover 53 shakes on the base 51 through the spring 52, so that the base 51 is not affected by vibration, thereby maintaining its stability in the vehicle and reducing the impact of the vibration of the generator 4 on the vehicle frame and inside the vehicle. The wire ropes 57 can elastically support the upper card seat 56 and the upper cover 53, further improving the elastic buffering and vibration buffering capabilities of the upper cover 53, maintaining the working stability of the generator 4, and improving the vehicle-mounted vibration isolation effect.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
