Description

Technical Field

[0001] This utility model belongs to the field of battery pack housing technology, specifically relating to a sheet metal top cover for a battery pack housing. Background Technology

[0002] The sheet metal cover of a continuous enclosure is typically made by stamping sheet metal into the required shape and size using stamping equipment. Stamping process parameters such as blank holder force and stamping speed need to be optimized to prevent defects such as wrinkling and cracking. Surface treatments, such as spraying and electroplating, are then applied to the sheet metal cover to improve its corrosion resistance and wear resistance, extending its service life.

[0003] In existing sheet metal covers, the interface position of the battery pack is usually reserved. When the battery pack is assembled with the car, the wiring connectors on the car are directly connected to the battery pack interface. However, in this connection method, the connectors are generally exposed on the outside of the battery pack. During the vehicle's operation, sewage and dust can easily adhere to the connectors. Over time, this can easily cause corrosion to the connectors and accelerate their aging. Moreover, sewage can easily seep in through the connectors, causing problems such as short circuits in the battery pack, which is not conducive to practical application.

[0004] Therefore, a sheet metal cover for the battery pack housing was designed to overcome the aforementioned technical defects. Utility Model Content

[0015] This specific embodiment is a sheet metal top cover for a battery pack housing, and its structural schematic diagram is shown below. Figures 1-5As shown, the device includes a cover 1. The side wall of the cover 1 has multiple wiring holes 2. Multiple sets of mounting plates 4 are fixedly connected to the side wall of the cover 1. Each set of mounting plates 4 consists of two plates, and the two mounting plates 4 in each set are located on both sides of the wiring holes 2. The mounting plates 4 have an L-shaped cross-section and a closed bottom surface. A baffle 3 is provided between the two mounting plates 4 in each set. A clamping component is provided between the mounting plates 4 and the baffle 3. The side wall of the baffle 3 has a wire inlet hole and a dustproof component.

[0016] like Figure 5 As shown, the clamping assembly includes a pressure plate 5 disposed between the mounting plate 4 and the baffle 3. Two positioning rods 6 are fixedly connected to the side wall of the pressure plate 5. The other end of the positioning rod 6 passes through the mounting plate 4 and is movably connected to it. The positioning rod 6 has a T-shaped cross-section. A spring 7 is sleeved on the side wall of the positioning rod 6 between the mounting plate 4 and the baffle 3. The top end face of the pressure plate 5 is inclined on the side near the cover 1.

[0017] The clamping component can be used to press and fix the baffle 3, preventing it from detaching due to vehicle bumps. In addition, when the connector and cable are passed through the inlet hole on the baffle 3, the baffle 3 can be limited again to further enhance its stability.

[0018] like Figure 5 As shown, a rubber pad 8 is fitted on the side wall of the positioning rod 6, and the two ends of the rubber pad 8 are fixedly connected to the mounting plate 4 and the pressure plate 5, respectively. The rubber pad 8 has a ring-shaped folding structure, which can move in a telescopic motion, so as to protect the spring 7 and prevent the spring 7 from being corroded by external factors, affecting the strength and durability of the spring 7, thereby effectively improving its performance.

[0019] like Figure 2 and Figure 4 As shown, a sealing ring 9 is fixedly connected to the side wall of the baffle 3 near the cover 1. A sealing groove 10 is provided on the side wall of the cover 1 at the edge of the wiring hole 2, and the sealing ring 9 is adapted to the sealing groove 10. When the clamping assembly clamps and fixes the baffle 3, the sealing ring 9 is inserted into the sealing groove 10, which can play a sealing role on the one hand, and enhance the connection stability between the baffle 3 and the cover 1 on the other hand.

[0020] like Figure 3 As shown, the dustproof component includes a folded tube 11 fixedly connected to the side wall of the baffle 3. The folded tube 11 is connected to the inlet hole, and a flexible hose 12 is fixedly connected to the other end of the folded tube 11. A clamp 13 is fitted on the side wall of the flexible hose 12.

[0021] Specifically, the material of the folding tube 11 is preferably rubber, which has good elasticity and corrosion resistance. When the vehicle is traveling at high speed, the splashed sewage or stones hitting the folding tube 11 can also play a buffering role and effectively prevent the joint from being hit. In addition, if the corresponding wiring hole 2 does not need to be connected to the connector, the clamp 13 can be tightened directly to seal the hose 12.

[0022] Working principle: When connecting the car connector to the battery pack interface, first thread the baffle 3 and folding tube 11 onto the connector cable. Then, insert the connector into the interface inside the battery pack through the wiring hole 2. Next, insert the baffle 3 between the two mounting plates 4. While inserting, use the inclined surface of the pressure plate 5 to move it outward, and at the same time, the spring 7 is compressed. After the baffle 3 is inserted into place, use the force of the spring 7 to squeeze the baffle 3, so that the sealing ring 9 on the baffle 3 is inserted into the sealing groove 10 for further sealing. Then, adjust the length of the folding tube 11 and tighten the clamp 13. The clamp 13 securely attaches the hose 12 to the cable surface, which serves to prevent dust and water, and effectively extends the service life of the connector.

[0023] All technical features in this embodiment can be freely combined according to actual needs.

[0024] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
