Abstract
Description
Technical Field
[0001] This utility model application relates to the field of battery box technology, specifically a lightweight, impact-resistant battery box. Background Technology
[0002] A battery box is a group of batteries consisting of several individual batteries, a box body, a battery management system, and related installation structural components (equipment). It has a standard battery box structure, battery box monitoring equipment, battery box connectors, battery box environmental control equipment, etc. With the promotion and development of new energy vehicles, more and more battery boxes are being used.
[0003] When the battery box is in use, its own weight also affects the overall weight of the power supply equipment. If the power supply equipment is too heavy, it will increase the weight of the vehicle. Therefore, most batteries currently use lightweight batteries. However, during the vehicle's operation, such as starting, braking, and collisions, the battery box may move and be impacted, which can significantly reduce the safety of the battery box during use. Summary of the Invention
[0004] To address the problem of poor impact resistance in existing battery boxes, this invention provides a lightweight impact-resistant battery box to solve the aforementioned issues.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A lightweight, impact-resistant battery box includes a battery box body and a cover. The cover is detachably fixed to the top surface of the battery box body with bolts. Impact-resistant frames are symmetrically fitted around the outer side of the battery box body. Side frames one are fixed to the outer surfaces of the left and right sides of the battery box body corresponding to the impact-resistant frames, and side frames two are fixed to the outer surfaces of the front and rear sides of the battery box body corresponding to the impact-resistant frames. Each side frame one and side frame two has a movable groove inside, and each movable groove has a sliding slider symmetrically connected to it. One end of each sliding slider extending outside the movable groove is rotatably connected to a linkage rod, and the other end of the linkage rod is rotatably connected to the inner wall of the impact-resistant frame. Springs are fixed between the two sliding sliders inside side frame one and between the sliding sliders and the side wall of the movable groove. Another spring is fixed between the two sliding sliders inside side frame two.
[0007] Furthermore, both sides of the top surface of the box cover are symmetrically connected with ventilation holes, and each ventilation hole is threaded with a protective cover, and a dustproof net is fixed inside the top surface of each protective cover.
[0008] Furthermore, each of the aforementioned anti-collision frames is configured as a hollow rectangular frame that fits into the battery box body, and the inner and outer surfaces at the corners of each of the aforementioned anti-collision frames are configured as arcs.
[0009] Furthermore, each of the movable slots is configured as a horizontally placed "convex" shape that cooperates with the movable slider, and a positioning slide rod is fixed inside each of the movable slots.
[0010] Furthermore, each of the movable sliders has a sliding hole inside that mates with the positioning slide rod, and each of the movable sliders and the spring is slidably sleeved on the positioning slide rod.
[0011] Furthermore, a buffer and heat-dissipating silicone sheet is adhesively fixed to the top surface of the cover outside the vent, and a shock-absorbing pad is adhesively fixed to the bottom surface of the battery box. The thickness of the shock-absorbing pad is equal to the thickness of the buffer and heat-dissipating silicone sheet.
[0012] Furthermore, the outer surface of the vent hole and the inner surface of the protective cover are provided with mutually mating threads, and the interior of the battery box is connected to the outside through the vent hole and the protective cover.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, the outer anti-collision structure allows the moving slider to compress the spring by squeezing the anti-collision frame during use. The spring's restoring force then offsets some of the compression, achieving an anti-collision buffering effect. Combined with the upper and lower shock-absorbing pads, it further protects the battery box, solving the problem of poor anti-collision performance of existing battery boxes and greatly improving the practicality and safety of the battery box during use.
[0015] 2. In this utility model, the buffer heat dissipation silicone sheet on the top can further protect the internal battery pack, while increasing the heat dissipation effect of the top surface of the box cover, thereby accelerating the heat dissipation of the internal battery. In addition, the vent holes on the top can effectively ensure the heat dissipation circulation inside the battery box and prevent the gas generated by the battery from accumulating inside the battery box.

Detailed Implementation
[0022] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] Reference Figure 1 , Figure 2 and Figure 3 A lightweight anti-collision battery box includes a battery box body 1 and a box cover 2. The box cover 2 is detachably fixed to the top surface of the battery box body 1 by bolts. Anti-collision frames 3 are symmetrically fitted on the outside of the battery box body 1. Each anti-collision frame 3 is a hollow rectangular frame that cooperates with the battery box body 1. The inner and outer surfaces of the corners of each anti-collision frame 3 are arc-shaped. Side frames 4 are fixed to the outer surfaces of the left and right sides of the battery box body 1 corresponding to the anti-collision frames 3. Side frames 5 are fixed to the outer surfaces of the front and rear sides of the battery box body 1 corresponding to the anti-collision frames 3. Each side frame 4 and side frame 5 has a movable groove 6 inside. Each movable groove 6 is configured to cooperate with a movable slider 7. The horizontally placed "convex" shape has a positioning slide rod fixed inside each movable slot 6, and a movable slider 7 is symmetrically slidably connected inside each movable slot 6. Each movable slider 7 has a sliding hole that cooperates with the positioning slide rod. Each movable slider 7 and spring 8 are slidably sleeved on the positioning slide rod. One end of each movable slider 7 extending to the outside of the movable slot 6 is rotatably connected to a linkage rod 9, and the other end of the linkage rod 9 is rotatably connected to the inner wall of the anti-collision frame 3. Springs 8 are fixed between the two movable sliders 7 inside the first side frame 4 and between the movable slider 7 and the side wall of the movable slot 6. Another spring 8 is fixed between the two movable sliders 7 inside the second side frame 5.
[0024] Specifically, when the battery box 1 is impacted by an external force, the impact force first acts on the anti-collision frame 3 on the outside of the battery box 1. When the anti-collision frame 3 is impacted, the linkage rod 9 rotates under the action of the impact force. When the linkage rod 9 rotates, it pushes the movable slider 7. When the movable slider 7 slides inside the movable groove 6, it stretches or compresses the spring 8. The restoring force of the spring 8 can offset part of the squeezing force. Moreover, the sliding design of the movable slider 7 and the movable groove 6 ensures that when the anti-collision frame 3 moves back and forth on the battery box 1, the side frames 4 on both sides will not restrict the anti-collision frame 3. Similarly, the side frames 5 will not restrict the anti-collision frame 3, thus ensuring the protective effect of the anti-collision frame 3.
[0025] As an optimization solution, such as Figure 1 and Figure 4 As shown, vent holes 11 are symmetrically fixed on both sides of the top surface of the cover 2. A buffer heat dissipation silicone sheet 12 is glued to the top surface of the cover 2 outside the vent holes 11. A shock-absorbing pad 10 is glued to the bottom surface of the battery box body 1. The thickness of the shock-absorbing pad 10 is equal to the thickness of the buffer heat dissipation silicone sheet 12. The outer surface of the vent holes 11 and the inner surface of the protective cover 13 are provided with mating threads. The interior of the battery box body 1 is connected to the outside through the vent holes 11 and the protective cover 13. Each vent hole 11 is threaded with a protective cover 13, and a dustproof mesh 14 is fixed to the inside of the top surface of each protective cover 13.
[0026] Specifically, the damping pads 10 can reduce the impact of vehicle body vibration on the battery box 1, and the buffer heat dissipation silicone pads 12 can increase the heat dissipation and buffering effect of the battery box 1. At the same time, the vents 11 can maintain the air circulation inside and outside the battery box 1, and the dustproof net 14 can protect the vents 11 to prevent dust and debris from causing blockage.
