[0002] Currently, battery-powered power tools are not only essential equipment for installation workers, but have also entered ordinary households on a large scale and are one of the loading and unloading equipment used for storage in ordinary households. Power tools are usually equipped with a DC battery pack. The use of existing battery packs is limited to providing power for power tools, and their uses have not been effectively expanded. The existing technology has developed power converters that can convert the DC power of the DC battery pack into power for other electronic products such as mobile phones, laptops, car refrigerators, and various travel, camping, and medical emergency appliances, which has brought convenience to people's lives.

[0003] The existing power converters generate a large amount of heat when in use, and the traditional power converter housing has a low cooling effect, which affects the long service life of the device. In addition, the power converter is easily affected by impact forces.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and an electric energy converter and its housing structure are proposed. Utility Model Content

[0011] Preferably, the power converter housing structure further includes a converter shell and a connection port, the converter shell is fixedly mounted on the bottom of the converter circuit board, and the front end of the converter circuit board is electrically connected to the connection port.

[0012] Compared with the prior art, the beneficial effect of the present invention is that the power converter and its housing structure can not only reduce the heat of the converter circuit board during operation, but also improve the buffering capacity of the converter circuit board when it is impacted.

[0013] 1. This utility model utilizes a heat dissipation assembly to allow an external pipe to inject coolant into the water flow channel inside the heat dissipation fins. The coolant flowing in the water flow channel then generates heat for the converter circuit board mounted at the bottom of the heat dissipation fins. Heat dissipation silicone grease is filled between the converter circuit boards to improve heat conductivity. The heated coolant is then discharged through the water pipe, forming a circulation system, thereby improving the heat dissipation capacity of the converter circuit board during operation.

[0014] 2. The utility model uses a buffer spring in conjunction with a damping rod so that when the converter circuit board is impacted and falls, the buffer spring and the damping rod are pulled simultaneously, and the buffer spring buffers the force of the converter circuit board falling. The damping rod then offsets the impact force when the buffer spring is reset, thereby greatly reducing the impact force on the converter circuit board, thereby achieving the purpose of improving the buffering capacity of the converter circuit board when it is impacted.

The connecting sleeve 504 is fixed to the left front end of the vertical plate 2, and threaded grooves 505 are provided at the four corners of the heat dissipation fin 501.

[0022] The external pipeline injects the coolant into the water flow channel 502 inside the heat sink 501, and then the coolant flowing inside the water flow channel 502 generates heat for the converter circuit board 10 installed at the bottom of the heat sink 501. The converter circuit boards 10 are filled with heat dissipation silicone grease to improve the heat conductivity. The heated coolant is discharged through the water pipe 503 to form a circulation, thereby improving the heat dissipation capacity of the converter circuit board 10 when working.

[0023] like Figure 4 As shown, the internal thread of the thread groove 505 is connected to the screw rod 6, and the top of the screw rod 6 is fixedly installed with a buffer tension spring 7.

[0025] Furthermore, a damping rod 8 is inserted into the interior of the buffer tension spring 7 , and the top of the damping rod 8 is rotatably connected to a connecting seat 9 .

[0026] The connecting seat 9 allows the damping rod 8 to have a certain range of movement when working.

[0027] Furthermore, the top of the connecting seat 9 is fixed to the outer shell frame 3 , and the heat dissipation fins 501 are elastically connected to the outer shell frame 3 via the damping rod 8 .

[0033] Working principle: When using the electric energy converter and its shell structure, the coolant is first injected into the water trough 502 inside the heat dissipation fin 501 through an external pipe, and then the coolant flowing in the water trough 502 generates heat for the converter circuit board 10 installed at the bottom of the heat dissipation fin 501, and the space between the converter circuit boards 10 and the converter circuit boards 10 is filled with heat dissipation silicone grease to improve the heat conductivity, and the heated coolant is discharged through the water pipe 503 to form a cold cycle, and when the converter circuit board 10 is impacted and falls, the buffer spring 7 and the damping rod 8 are pulled at the same time, and the buffer spring 7 buffers the force of the converter circuit board 10 falling, and the damping rod 8 offsets the impact force when the buffer spring 7 is reset, so that the impact force on the converter circuit board 10 is greatly reduced, so as to achieve the purpose of improving the buffering capacity of the converter circuit board 10 when it is impacted. This is the working principle of the electric energy converter and its shell structure.
