DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A battery box locking mechanism for a battery-swap heavy-duty truck includes a base assembly 1, an electric push rod 2 and a fixing bolt 3. The base assembly 1 includes a base body 101. The base body 101 has good structural strength and stability and can withstand the weight of the battery box and various forces and vibrations generated during the driving of the vehicle. An adjustment groove 102 is provided on one side of the base body 101. A row of adjustment holes 103 are provided on one side of the adjustment groove 102. A mounting hole is provided at the bottom end of the electric push rod 2. The electric push rod 2 is threadedly connected to the adjustment groove 102 through the fixing bolt 3. The fixing bolt 3 is fixedly threaded through the adjusting hole 103 and the mounting hole. The fixing bolt 3 passes through the adjusting hole 103 in sequence. 3 and the mounting hole, the electric push rod 2 is fixed on the base body 101, and by selecting different adjustment holes 103, the position of the electric push rod 2 in the adjustment slot 102 can be flexibly adjusted to adapt to battery boxes of different sizes. When working, the electric push rod 2 can accurately extend or retract the push rod according to the command of the control system to achieve the locking and unlocking operations of the battery box. When the battery box needs to be locked, the electric push rod 2 is extended, and the end of the push rod contacts and applies pressure with the corresponding part on the battery box to firmly fix the battery box on the base. When the battery box needs to be unlocked, the electric push rod 2 is retracted to release the pressure on the battery box, so that the battery box can be safely taken out or replaced.

[0022] Two extension ends are provided on one side of the first bracket 401, and a row of card slots 403 are respectively provided on the outer walls of the two extension ends. The function of the card slots 403 is to provide multiple fixed position options when locking the battery box to adapt to battery boxes of different sizes, thereby enhancing the versatility of the locking mechanism. A slide slot 402 is provided at the bottom of the two extension ends. The second adjustment component 5 includes a second bracket 501, and two extension ends are provided on one side of the second bracket 501. Adjustment rods 502 are respectively provided on the tops of the two extension parts. The adjustment rods 502 are slidably fitted in the slide slots 402, so that the relative position between the first adjustment component 4 and the second adjustment component 5 can be flexibly adjusted according to actual needs, thereby better adapting to battery boxes of different sizes. The first adjustment component 4 and the second adjustment component 5 are in a "C" shape, and the first adjustment component 4 and the second adjustment component 5 are combined into a "mouth" shape, ensuring that the battery box will not loosen or move during the driving of the vehicle, thereby improving the installation stability and safety of the battery box. The base component 1 is connected to the first adjustment component 4 and the second adjustment component 5 through the electric push rod 2;

[0023] Horizontal quick clamps 6 are respectively provided at the top corners of the first bracket 401 and the slide groove 402. There are four horizontal quick clamps 6. A clamp and a handle are provided on the horizontal quick clamp 6. The clamp is located above the base assembly 1 to ensure that the battery box will not move or shake in the locked state. The clamp can be clamped and released by simple operation of the handle, which greatly improves the installation and disassembly efficiency of the battery box. After the electric push rod 2 adjusts the first adjustment assembly 4 and the second adjustment assembly 5 to the appropriate position, the operator can operate the handle of the horizontal quick clamp 6 to make the clamp tightly clamp the battery box. Under the locking action of the electric push rod 2 and the clamping action of the horizontal quick clamp 6, the battery box can be firmly installed on the heavy truck, providing reliable power support for the normal operation of the vehicle.

[0024] The size of the adjusting rod 502 matches the size of the slide groove 402. The second bracket 501 is slidably connected to the first bracket 401 through the adjusting rod 502. A groove is provided at the top of the adjusting rod 502. The spring 503 is installed on one side of the groove. The block 504 is connected to the adjusting rod 502 through the spring 503. One side of the block 504 is overlapped on the top of the adjusting rod 502. The spring 503 can generate corresponding elastic force when compressed or stretched. When the adjusting rod 502 slides in the slide groove 402, the block 504 will be squeezed by the inner wall of the slide groove 402, compressing the spring 503, so that the block 504 is temporarily retracted into the groove. When the adjusting rod 502 slides to the position corresponding to the slot 403, the elastic force of the spring 503 will pop out the block 504. , so that it is stuck in the slot 403, the spring 503 runs through the slot 403 and extends to the outside of the first bracket 401, playing the role of fixing the position of the adjustment rod 502, thereby realizing the locking of the relative position between the first adjustment component 4 and the second adjustment component 5. When the size needs to be adjusted, the operator can press the block 504 to make the block 504 compress the spring 503 and enter the groove of the adjustment rod 502. At this time, the adjustment rod 502 can slide freely in the slide groove 402 to achieve the purpose of adjusting the size of the bracket. When it is adjusted to a suitable position, the pressure on the spring 503 is released, and the block 504 is re-extended under the elastic force of the spring 503 and stuck in the slot 403, thereby realizing the fixing of the position of the adjustment rod 502.

[0025] When using the device, first connect the power supply to the electrical equipment in the device, place the device at the designated working position, and cooperate with the base assembly 1, the electric push rod 2, the first adjustment assembly 4 and the second adjustment assembly 5 to be compatible with a variety of battery boxes of different sizes and models, without being restricted by the size and model of the battery box, so that electric heavy-duty trucks have greater flexibility when replacing battery boxes, and can easily replace and maintain battery boxes, thereby improving work efficiency, better adapting to the development of future battery technology and changes in battery box size, and making it easier to upgrade and improve vehicles.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
