Description

Technical Field

[0001] This utility model relates to the field of electric vehicle component technology, and in particular to an electric vehicle battery terminal protection component. Background Technology

[0002] With the rapid development of the new energy vehicle industry, electric vehicles are gradually becoming more popular as an important means of green transportation, with their core power source being the battery pack. Electric vehicle batteries typically consist of several individual cells, which are electrically connected to the vehicle's electronic control system via wires and connectors, thus providing stable power to the motor, controller, and other components. To ensure range and safety, electric vehicle batteries must be securely fixed inside the vehicle's battery compartment during installation and form a reliable circuit connection with the vehicle's electrical system through wiring.

[0003] In existing electric vehicle structures, after the battery pack is connected to components such as the controller and motor via cables, these cables typically need to be housed within the limited space of the battery compartment or footrest area to avoid exposure and ensure riding safety. However, because the battery compartment design requires a secure connection between the battery and the compartment body, the cables are often compressed or bent during installation. This can lead to insulation damage, breakage, or poor contact in the cables over long-term use. This not only affects the stable connection between the battery and the vehicle but can also cause safety hazards such as reduced power transmission efficiency, localized overheating, and even short circuits. Furthermore, the limited space for cable routing and the lack of reasonable guiding or buffering structures complicate battery replacement and maintenance, further increasing usage risks and maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing electric vehicle battery wiring methods generally suffer from limited layout space, easy damage to cables due to pressure, and significant safety hazards.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an electric vehicle battery terminal protection component, including a pair of side plates, the side plates are configured as C-shaped frame plate structures, and the two side plates are symmetrically arranged. A recess is opened in the center of the side plate, and a cable management plate is fastened in the recess. Multiple evenly spaced cable clips are fixedly arranged in the center of the cable management plate. Multiple semi-circular grooves are opened through one side of the cable clips. A rotating shaft seat is fixedly arranged on the top of the side plate. A buffer pressure plate is inserted into one side of the rotating shaft seat. Inserts and cylinders are fixedly connected to the bottom of the two side plates respectively. The inserts are provided with multiple combined screw holes, and the inserts and cylinders are fastened together by combined bolts.

[0006] As a further improvement of this utility model, the cable management plate is configured as a rectangular plate structure, and one side is fastened to the recessed chamber. Multiple limiting rings are fixedly provided at the two side edges of the cable management plate.

[0007] As a further improvement of this utility model, ear plates are fixedly connected to both sides of the recess, and a pair of fastening bolts are passed through the center of the ear plates, and the fastening bolts are fastened to the cable management plate.

[0008] As a further improvement of this utility model, the rotating shaft seat is fixedly connected to a strip plate for the buffer pressure plate to be inserted through a rotating shaft, and a damping sleeve is sleeved at the connection between the rotating shaft and the rotating shaft seat.

[0009] As a further improvement of this utility model, the buffer plate is configured as a double-layer clamping plate that is fixed to each other, with the top plate and the strip insert plate being tightly inserted together, and the bottom plate being tightly abutting against the edge of the battery module.

[0010] As a further improvement of this utility model, the top of the insert is fixedly connected with a toggle finger buckle, and the top of the insert tube is provided with a horizontal groove for the toggle finger buckle to pass through.

[0011] The beneficial effects of this utility model are as follows: By setting recesses and cable management plates in the side panels, the battery wiring cables can be oriented in an independent space, avoiding the problem of cables being directly squeezed and bent by the battery compartment in traditional structures. The tight fit between the limiting rings on both sides of the cable management plate and the ear plates further enhances the stability of the cable fixation, making the cables less prone to displacement during vibration or battery installation and removal. The buffer pressure plate, through the cooperation of the rotating shaft seat and the strip insert plate, can form a buffer pressure on the battery module during installation, avoiding rigid compression of the cables and protecting the cable insulation layer and connection stability. The combination structure of the bottom insert strip and the insert cylinder, as well as the setting of the toggle finger buckle, allows the side panel spacing to be quickly adjusted according to the width of the battery module, ensuring both installation flexibility and the protective effect of the battery compartment's internal space on the cables.

[0020] This utility model provides a battery terminal protection assembly for electric vehicles, including a pair of side plates 1;

[0021] As attached Figure 2 , 3 As shown in Figure 4, the side plate 1 is a C-shaped frame structure, and the two side plates 1 are symmetrically arranged. A recess 2 is provided in the center of the side plate 1, and a cable management plate 3 is fastened in the recess 2. Ear plates 9 are fixedly connected to both sides of the recess 2, and a pair of fastening bolts are inserted through the center of the ear plates 9. The fastening bolts are fastened to the cable management plate 3 to reinforce the connection of the cable management plate 3. Multiple evenly spaced cable clamping strips are fixedly provided in the center of the cable management plate 3. Multiple semi-circular grooves are provided through one side of the cable clamping strips for cable clamping. The cable management plate 3 is a rectangular plate structure, and one side is fastened to the recess 2. Multiple limiting rings 8 are fixedly provided at the two edges of the cable management plate 3. A rotating shaft seat 4 is fixedly provided at the top of the side plate 1, and a buffer pressure plate 5 is inserted into one side of the rotating shaft seat 4.

[0022] As attached Figure 2As shown, the rotating shaft seat 4 is fixedly connected to a strip-shaped insert plate 10 for the buffer pressure plate 5 to insert into via a rotating shaft, and a damping sleeve is fitted at the connection between the rotating shaft and the rotating shaft seat 4 to increase the friction during rotation. The buffer pressure plate 5 is configured as a fixed double-layer clamping plate, with the top plate tightly inserted into the strip-shaped insert plate 10, and the bottom plate tightly abutting against the edge of the battery module. The top plate is used to snap onto the top plate of the battery compartment.

[0023] As attached Figure 3 , 4 As shown, the bottom of the two side plates 1 are respectively fixedly connected with insert strips 6 and insert cylinders 7. Insert strips 6 are provided with multiple combined screw holes, and insert strips 6 and insert cylinders 7 are fastened together by combined bolts. A toggle finger buckle 11 is fixedly connected to the top of insert strips 6, and the top of insert cylinder 7 is provided with a transverse groove for the toggle finger buckle 11 to pass through; this facilitates the adjustment of the width by toggle.

[0024] Working Principle: In practical application, this invention involves placing the electric vehicle battery module into a frame composed of two symmetrically arranged side plates 1. Cables are first introduced into one side of the recess 2 in the center of side plate 1 and evenly clamped into the cable clamping strips on the cable management plate 3. The semi-circular grooves on the cable clamping strips provide directional restraint, ensuring the cables remain neatly arranged within the recess 2 and preventing arbitrary bending. Simultaneously, the limiting rings 8 on both sides of the cable management plate 3 further constrain and guide the cables, ensuring stable cable routing. The ear plates 9 on both sides of the recess 2 are securely fixed to the cable management plate 3 with fastening bolts, ensuring that the cable management plate 3 does not loosen during long-term use, thus maintaining the reliability of the cable layout. During battery module installation, the rotating shaft seat 4 drives the buffer pressure plate 5 to rotate around the rotating shaft. When the battery top plate abuts, the buffer pressure plate 5 achieves elastic clamping through the double-layer clamping structure formed by the strip-shaped insert 10. The damping sleeve provides frictional resistance during rotation, preventing the battery from being subjected to excessive force or hardness, thereby providing buffer protection for the cables. The bottom insert 6 and insert 7 are connected by a combination bolt to form an adjustable fixing structure. Users can pull or loosen the insert 7 by moving the finger buckle 11 through the transverse groove of the insert 7 to adjust the spacing of the side plate 1, thereby adapting to battery modules of different specifications and preventing excessive compression of cables inside the compartment. Through the above actions, the battery module can be secured while maintaining a reasonable distribution of cables and stress buffering, which improves wiring stability and reduces the risk of damage.
