[0012] Advantages

[0013] 1、In the prior art, the installation process of the battery pack of the traditional power module is relatively complicated, which brings many inconveniences in actual use. First, due to the complex installation steps, professional personnel is often required to operate, which not only increases the initial setting cost, but also prolongs the equipment deployment time. For emergency or temporary application scenarios, such delay may adversely affect the project progress. To solve such problems, the utility model utilizes the bolt structure. When the staff needs to replace and install the module, the staff pushes the first sliding block to move left, and at the same time, pushes the elastic sliding bolt to move into the second sliding block with the help of the fixed column, until the fixed column moves to the rear end of the elastic sliding bolt. At this time, the elastic sliding bolt is ejected, and then the first sliding block is moved right until the fixed bolt is separated from the lock pin, so that the cover plate can be opened to replace the battery pack block inside the module shell. After replacement is completed, the user presses the cover plate, and at the same time, continues to push the first sliding block right with the other hand, until the elastic sliding bolt moves to the surface of the locking tooth, and then the elastic sliding bolt moves into the second sliding block, until the elastic sliding bolt is separated from the fixed column, and then the spring pushes the reset lock pin, so as to complete the sealing, thereby realizing quick disassembly and improving the maintainability and flexibility of the power module.

[0014] 2、In the prior art, the traditional power module is usually fixed by conventional bolts. Although this fixing method can ensure stable operation of the device at the initial stage, the bolts are prone to loosen or even fall off due to various reasons over time, thereby potentially threatening the normal operation of the device. After a long time of operation, the bolts may gradually loosen due to factors such as vibration and temperature change. In industrial sites or outdoor environments, the device is often affected by various mechanical vibrations and impacts. These forces will gradually be transmitted to the fixed bolts, causing the fastening force to decrease. To solve such problems, the utility model increases the elastic sheet in the bolt connection. The elastic sheet can provide a continuous pre-tightening force. When the bolt and the nut are tightened, the elastic sheet will generate a continuous compression force on the bolt due to its elastic properties. This force can be converted into a pre-tightening force on the bolt, preventing the bolt from loosening due to external forces. When subjected to vibration or impact, the elastic sheet can absorb part of the energy, reducing the influence of these external forces on the bolt connection. The continuous elastic force of the elastic sheet can make the nut and bolt thread connection pair continuously maintain a friction force, generating a resistance torque, thereby preventing the nut from loosening and avoiding the problem of device damage caused by bolt loosening.
