[0002] A gasoline generator is a power generation device that uses gasoline as fuel. It converts chemical energy into electrical energy through the working principle of an internal combustion engine. It is usually used for temporary or emergency power supply, such as providing backup power for homes during power outages, for use in camping or outdoor activities, or when power tools are needed on construction sites.
[0003] However, the engine of the gasoline generator will produce strong vibrations during operation, and long-term operation will cause the internal components of the engine and the components on the equipment to become loose, making the engine unstable. In severe cases, it may cause damage to the equipment or the engine. In addition, the engine will produce relatively loud noise when working, and the existing gasoline generators have relatively poor shock absorption and noise reduction functions, which are not convenient to use, and to a certain extent affect the service life of the gasoline generator. For this reason, we propose a shock absorption and noise reduction gasoline generator to solve the above problems. Utility Model Content

[0021] In the embodiment of the present application, when in use, the gasoline generator body 11 is installed at the bottom of the inner cavity of the protection box 1, and then after the gasoline generator body 11 is installed, the upper end cover 2 is covered on the upper end of the protection box 1 for fixing. After fixing, the buffer pad 13 is in contact with the upper end surface of the gasoline generator body 11. When the gasoline generator body 11 is working, the vibration generated will squeeze the third spring 8 to deform it, and cooperate with the second damper 9 and the buffer pad 13 to buffer the vibration force, thereby facilitating the shock absorption of the top of the gasoline generator body 11. At the same time, the gasoline The vibration generated when the generator body 11 is working presses the shock absorbing assembly 53 downward, causing the shock absorbing assembly 53 to move downward to squeeze the first spring 532 and deform it.

[0023] Furthermore, an installation slot is opened in the middle of the top of the upper end cover 2, and a heat dissipation fan 3 is fixedly installed in the installation slot.

After fixing, the buffer pad 13 is in contact with the upper end surface of the gasoline generator body 11. When the gasoline generator body 11 is working, the vibration generated will squeeze the third spring 8 to make it deform, and cooperate with the second damper 9 and the buffer pad 13 to buffer the vibration force, thereby facilitating the shock absorption of the top of the gasoline generator body 11. At the same time, the vibration generated when the gasoline generator body 11 is working squeezes the shock absorbing assembly 53 downward, so that the shock absorbing assembly 53 moves downward to squeeze the first spring 532 , causing it to deform. During the downward movement of the support block 531, the pull rod 538 will be pulled, thereby driving the moving block 537 to slide along the inner cavity of the sleeve 535 to squeeze the second spring 536, causing it to deform, thereby facilitating the buffering of the vibration force. In conjunction with the function of the first damper 533, it is convenient to buffer and reduce shock to the vibration force, and the overall shock absorption effect is good, reducing the noise generated by vibration while increasing the service life of the gasoline generator body 11.
