Description

Technical Field

[0001] The present invention relates to the technical field of truck battery packs, and in particular to a new energy semi-trailer truck battery pack with a safety protection function. Background Art

[0002] With the rapid development of the global economy and growing awareness of environmental protection, the high energy consumption, high pollution levels, and reliance on non-renewable energy sources of traditional fuel trucks have gradually become key bottlenecks hindering the sustainable development of the logistics and transportation industry. At the same time, the rapid development of new energy technologies has brought new transformational opportunities to the transportation sector. New energy semi-trailer trucks have emerged as a key development direction for the future of the logistics and transportation industry. To meet the long-distance haul requirements of semi-trailer trucks, new energy semi-trailer trucks require ultra-large battery packs. However, since new energy semi-trailer trucks often travel on rough roads, they are subject to significant bumps, vibrations, and bumps during operation. This can cause loosening and damage to the battery modules, which can easily lead to battery short-circuit damage, thus affecting the reliability and service life of the vehicles.

[0003] The existing new energy semi-trailer truck battery pack is composed of multiple components. When the battery pack is installed inside the new energy semi-trailer truck, a protective cover will be installed on the surface of the battery pack to wrap and protect the battery module to withstand the vibration, impact and collision of the new energy semi-trailer truck during driving. At the same time, the protective cover is generally fixed on the surface of the battery module by welding during installation, so that the battery module is in a relatively sealed environment, reducing the flow of moisture in the environment to the battery module and affecting the normal operation of the battery module. The welded and fixed protective cover is not easy to remove when the battery module is inspected and replaced. Relying on violent disassembly will cause damage to the protective cover. Therefore, improvement is needed.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a mounting base, a positioning slot, a protective cover, a movable block, a movable clamping block and a fixed clamping block. After the battery module is clamped and fixed on the top of the mounting base, the movable protective cover is suspended on the top of the mounting base so that the positioning plug on the inner wall of the protective cover corresponds to the position of the positioning slot on the top of the mounting base. The protective cover is moved down to cover the top of the mounting base so that the positioning plug is inserted into the positioning slot. The movable block is pressed down to slide on the surface of the mounting column to squeeze the surface of the top spring.

At the same time, the bottom end of the fixed plug rod is close to the mounting base, and the fixed plug rod is lifted and retracted into the inside of the mounting groove to limit the battery module. The positioning pressure plate moves upward inside the first installation slot, squeezing the fixing spring to deform, pushing the concave pressing frame to move on the top of the battery module, so that the clamping protrusion is clamped and fixed inside the clamping slot until the position of the fixing rod corresponds to the position of the fixing hole. Under the rebound action of the fixing spring, the limiting pressure plate is pressed downward to drive the fixing rod to move downward and extend out of the first installation slot and insert into the fixing hole, so that the concave pressing frame is clamped and fixed on the top of the battery module, pressing and fixing the battery module inside the placement slot, ensuring that the battery module inside the placement slot will not shake arbitrarily due to the movement of the installation base plate; 3.

The protective cover 5 is moved down to cover the top of the mounting base plate 1, and the battery module 3 is wrapped inside the protective cover 5 until the protective cover 5 is tightly attached to the top of the mounting base plate 1, driving the positioning block 501 to be inserted into the positioning slot 106, so that the position of the movable block 509 is opposite to that of the fixed slot 107. After the jacking spring 506 is released, the movable block 505 is lifted up and slid on the surface of the mounting post 504, pushing the connecting strip 508 to gradually become horizontal, so that the connecting strip 508 pushes the movable block 509 to slide on the surface of the T-shaped slide bar 507 and extend out of the mounting slot 2 502 and insert into the corresponding fixed slot 107. Then, the fixed block 510 is inserted into the sliding slot 503 so that the fixed block 510 is stuck at the bottom of the movable block 505. The fixing bolt 511 is tightened and passed through the fixed block 510 to connect with the protective cover 5, and the fixed block 510 is clamped and fixed inside the sliding slot 503. The movable block 505 is clamped and fixed, thereby fixing the protective cover 5 on the top of the mounting base plate 1 to shield and protect the battery module 3 placed on the top of the mounting base plate 1. When the battery module 3 needs to be disassembled and repaired, loosen the fixing bolt 511 to pull the fixed block 510 out of the sliding slot 503, press the movable block 505 downward to drive the connecting pull bar 508 to tilt and rotate, so that the connecting pull bar 508 pulls the movable block 509 to slide on the surface of the T-shaped slide bar 507 to disengage from the fixed slot 107 and retract into the inside of the second installation slot 502, then lift the protective cover 5 and pull the positioning block 501 out of the positioning slot 106, so that the protective cover 5 and the mounting base 1 are separated, and the protective cover 5 is removed from the mounting base 1. After moving away from the top of the battery module 3, push the lever 408 to slide up inside the movable slide groove 404, driving the fixed plug rod 405 to move up and disengage from the fixed socket 104 and retract into the installation slot 1 403. After the fixed plug rod 405 is completely pulled out from the fixed socket 104, push the concave pressing frame 4 to slide on the surface of the battery module 3, driving the snap-fitting protrusion 401 to slide and be pulled out inside the snap-fitting slide groove 105, and remove the concave pressing frame 4 from the surface of the battery module 3, thereby facilitating the removal of the battery module 3 from the inside of the placement slot 103 for inspection and replacement.
