[0002] Generators can drive the internal rotor to rotate through external force, and cooperate with corresponding windings to convert mechanical kinetic energy into electrical energy. Therefore, they are widely used in various industries. However, during the actual operation of the generator, due to the influence of mechanical energy, more or less vibration will be generated, thereby affecting the operation of the generator. At the same time, it will also have a certain impact on the mechanical structure of the device. Therefore, the mechanism of the generator often includes a corresponding shock-absorbing structure. However, this shock-absorbing structure can only reduce the negative impact of mechanical kinetic energy on the device, and cannot be fully utilized, affecting the overall power generation efficiency.

[0007] As an improvement, there are four groups of triangular teeth, which are arranged at equal intervals with the axis of the transmission rod as the center, and the tip corners of the top of the triangular teeth are chamfered with arcs.

[0008] As an improvement, the transmission rod is made of metal, and a gap of 0.2 mm is left at the connection between the rotating sleeve and the transmission rod.

[0009] The beneficial effects of the present invention are as follows: by arranging a rotating sleeve, the force generated by the vibration downward can be converted into axial rotational mechanical energy in cooperation with the fixed sleeve, and mechanical energy recovery can be achieved in cooperation with the corresponding power generation device.

[0014] like Figure 1 and Figure 2 As shown, a shock absorbing device for converting vibration energy into electrical energy comprises a rotating sleeve 2, a fixed sleeve 5 and a transmission rod 6, wherein the transmission rod 6 is cylindrical in shape and has a limiting end 1 at one end, the maximum width of the limiting end 1 is greater than the diameter of the transmission rod 6, the rotating sleeve 2 is slidably sleeved and connected to the transmission rod 6, a gasket is provided on the side of the rotating sleeve 2 close to the limiting end 1, the gasket is fixedly connected to the transmission rod 6, the inner side of the rotating sleeve 2 is provided with a groove, a spring 8 is fixedly provided on the inner side of the groove, one end of the spring 8 is fixedly connected to the gasket, the outer side of the rotating sleeve 2 is provided with a transmission tooth block 4, the lower end of the rotating sleeve 2 is fixed with a triangular tooth 3, the fixed sleeve 5 is located on the side of the rotating sleeve 2 away from the limiting end 1, the inner side of the fixed sleeve 5 is plugged with a limiting pin 7 and fixedly connected to the transmission rod 6, the upper end of the fixed sleeve 5 is provided with a triangular tooth 3 and is movably connected with the rotating sleeve 2. The rotating sleeve 2 and the fixed sleeve 5 can be replaced with different sizes and types according to usage requirements. A rotating sleeve seat is provided between the spring 8 and the rotating sleeve 2 to reduce the friction between the rotating sleeve 2 and the spring 8.

[0015] The maximum diameter of the rotating sleeve 2 is larger than the diameter of the fixed sleeve 5. The transmission gear block 4 is trapezoidal in shape. The short side of the transmission gear block 4 is arranged toward the limit end 1. The transmission gear block 4 is used to transmit power to the generator. There are four groups of triangular teeth 3, which are arranged at equal intervals with the axis of the transmission rod 6 as the center. The top corners of the triangular teeth 3 have arc chamfers.

[0016] When in use, the operator can install the device near the base or the generator drive shaft limit device, and make the transmission rod 6 resist the vibration position, and use the fixing block to install and fix the limit end 1, and then match and connect the rotating shaft of the secondary power generation device with the transmission tooth block 4 of the rotating sleeve 2; when the generator is running and vibrating, the transmission rod 6 will move downward, and the fixed sleeve 5 will press against the rotating sleeve 2. At this time, the triangular teeth 3 will obliquely push the rotating sleeve 2 to rotate, and at the same time drive the transmission tooth block 4 to rotate to assist power generation, and then the spring 8 will lift the rotating sleeve 2 again, so that the triangular teeth 3 are misaligned and separated, and are squeezed again to drive reciprocating rotation, thereby fully utilizing mechanical energy to assist power generation.
