Description

Technical Field

[0001] This invention relates to the field of battery swapping technology for new energy vehicles, and in particular to a side mounting and fixing device for a heavy-duty truck battery box. Background Technology

[0002] In recent years, battery swapping has become a trend in new energy electric heavy-duty trucks, effectively solving the shortcoming of long battery charging times that negatively impact the economic efficiency of heavy-duty trucks. To avoid occupying limited cargo space, installing batteries on the bottom sides of the cargo box has become a popular practice. However, current heavy-duty truck structural designs limit the space available for side-mounted battery boxes; therefore, how to quickly and reliably securely attach the battery boxes to the heavy-duty truck is a pressing practical problem that needs to be solved. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a side mounting and fixing device for heavy-duty truck battery boxes. The present invention adopts a simple and reliable structure to fix and install the battery box, making the battery box volume large enough to increase the driving range of heavy-duty trucks, while also meeting the design requirements of automatic battery swapping for heavy-duty trucks.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a side mounting and fixing device for a heavy-duty truck battery box, comprising: a battery box bracket, a battery box frame, a positioning pin, a limit block drive cylinder, and a limit block; the battery box frame is connected to the battery box bracket; the positioning pin is fixed to the battery box bracket by screws, the limit block drive cylinder is fixed to the battery box bracket by screws, and the limit block is connected to the battery box bracket by a sliding groove and is connected to the extension rod of the limit block drive cylinder.

[0005] Preferably, the battery box bracket has a guide opening, a support plate, and a limiting plate; the support plate is welded to the guide opening and the limiting plate respectively.

[0006] Preferably, the battery box frame is equipped with positioning blocks, and the positioning blocks are designed with positioning holes.

[0007] Preferably, there are two battery box brackets, which are respectively arranged on both sides of the battery box installation position. The battery box brackets are welded as a whole and connected to the heavy truck beam to form a stable whole.

[0008] Preferably, the battery box bracket has a simple structure and occupies little space, thus reserving more space for the battery box frame under the constraint of a fixed total space.

[0009] The beneficial effects of the present invention are as follows: (1) The present invention fixes the battery box bracket to the heavy truck chassis beam, so that the battery box bracket and the heavy truck form a stable whole, thereby improving the stability of the battery box; (2) The present invention adopts the method of supporting the battery box on both sides, which reduces the space occupied by the battery box bracket and reserves space for the overall disassembly and assembly of the battery box.

[0014] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto:

[0015] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a side mounting and fixing device for a heavy-duty truck battery box comprises a battery box bracket 1 and a battery box frame 2. The battery box bracket 1 includes a guide opening 3, a support plate 4, and a limiting plate 5, which are welded together. The battery box bracket 1 also includes a positioning pin 6, a limiting block drive cylinder 7, and a limiting block 8. The positioning pin 6 is fixed to the battery box bracket 1 with screws, and the limiting block drive cylinder 7 is also fixed to the battery box bracket 1 with screws. The limiting block 8 is mounted on the battery box bracket 1 via a sliding groove and is connected to the extension rod of the limiting block drive cylinder 7. Under the drive of the limiting block drive cylinder 7, it performs locking and unlocking actions within the sliding groove. The battery box frame 2 includes a positioning block 9 with positioning holes 10.

[0016] In use, the battery box frame 2 is inserted into the battery bracket 1 via bottom or side support by the positioning block 9 along the guide opening 3. After insertion, the positioning block 9 is restricted by the limiting plate 5 and cannot be inserted further. The external mechanism moves the battery box frame 2 downward, and the positioning hole 10 and positioning pin 6 guide and cooperate with each other to accurately position the battery box frame 2 and restrict its horizontal and rotational freedom. After the positioning block 9 contacts the support plate 4, the overall installation of the battery box frame 2 is completed. The limiting block drive cylinder 7 drives the limiting block 8 to move forward, locking the upward movement space of the battery box frame 2 and restricting its vertical downward movement. The locking action of the battery box frame 2 is completed.

[0017] This invention arranges the battery on the side of the heavy truck using a battery box bracket, avoiding the occupation of cargo box space; the brackets on the left and right sides provide operating space at the bottom and sides for battery replacement, facilitating the replacement of the battery body; the battery box frame is fixed in the battery box bracket through mechanisms such as support plates, limit plates, positioning pins, and limit blocks, ensuring the safety and stability of the battery body when the heavy truck is in motion.

[0018] The above description describes specific embodiments of the present invention and the technical principles employed. Any changes made in accordance with the concept of the present invention that do not exceed the spirit of the specification and drawings should still fall within the protection scope of the present invention.
