[0002] With the development and popularization of transportation, low-carbon travel has become the choice of more and more people, and new energy passenger vehicles are playing an increasingly important role in people's daily travel. The battery box is an essential part of new energy passenger vehicles, which is usually composed of battery packs, modules and cells. Its main functions include helping to dissipate heat from the battery, ensuring battery insulation and waterproofing, and protecting the battery from impacts.

[0003] However, existing battery boxes are usually installed by direct fixation and lack effective shock absorption design. This means that when the vehicle is driving on bumpy roads, the battery box is susceptible to huge vertical impacts and vibrations, and the shock absorption effect is very poor. In this case, the cells and connecting parts inside the battery box will wear out due to severe vibration. Long-term operation will lead to a reduction in battery life and pose serious safety hazards.

[0004] Therefore, there is an urgent need for a battery pack fixing structure for new energy passenger vehicles to solve the above problems. Utility Model Content

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 3As shown, this embodiment provides a battery box fixing structure for a new energy passenger vehicle. The battery box fixing structure for the new energy passenger vehicle includes multiple shock-absorbing components 100, which are disposed at the bottom of the battery box 200. Each shock-absorbing component 100 includes a support plate 1, multiple connectors 2, multiple support cylinders 3, and multiple elastic elements. The multiple support cylinders 3 are fixedly disposed on the support plate 1, and the multiple support cylinders 3 are correspondingly disposed with the multiple elastic elements. The elastic elements are housed inside the support cylinders 3, and the multiple elastic elements are correspondingly disposed with the multiple connectors 2. One end of the connector 2 slides through the top end of the support cylinder 3 and is connected to the bottom of the battery box 200. The other end of the connector 2 abuts against one end of the elastic element, and the other end of the elastic element is connected to the inner wall of the support cylinder 3 or the support plate 1. This configuration, by systematically arranging multiple shock-absorbing components 100 at the bottom of the battery box 200 and fixing them with connectors 2, constructs an active shock absorption system. Through elastic elements, it absorbs vibrations and impacts generated during driving or operation, further buffering and reducing the direct impact of external forces on the battery box 200, avoiding physical damage to the battery due to collisions or bumps, providing basic vibration protection for the precision components inside the battery box 200 (such as junction boxes, fuses, etc.), while ensuring the firmness of the shock-absorbing components 100 themselves, stabilizing the position of the battery box 200, preventing it from shaking or shifting during vehicle movement, reducing secondary impacts caused by inertia, and ensuring the safety and reliability of the battery box 200 during operation.

[0031] It should be noted that the battery box fixing structure for new energy passenger vehicles provided in this embodiment has wide versatility and good expandability, and can adapt to different models, different battery capacities and various complex working conditions, meet the protection needs of new energy vehicles in different application scenarios, and overcome the limitations of existing technologies that are difficult to meet diverse needs.

[0032] Optionally, in order to ensure the connection stability of the shock absorber 100, the shock absorber 100 also includes a connecting plate 4, one end of the connector 2 passes through the connecting plate 4 and is connected to the battery box 200.

[0033] Optionally, the damping component 100 includes a buffer pad disposed between the connecting plate 4 and the bottom surface of the battery box 200. Further, the buffer pad is made of rubber material. This arrangement allows the rubber-made buffer pad to suppress fine high-frequency vibrations and provide damping. Working in conjunction with the elastic element, it comprehensively absorbs and isolates high-frequency vibrations, significantly improving damping performance.

[0034] Optionally, the number of support cylinders 3 is four, and the four support cylinders 3 are respectively set at the four corners of the support plate 1.

[0035] Optionally, the shock absorption assembly 100 further includes a buffer cylinder 5, which is disposed at the center of the support plate 1 and forms a buffer gap with the connecting plate 4. The buffer cylinder 5 is capable of elastic deformation. This configuration allows the buffer gap between the buffer cylinder 5 and the connecting plate 4 to form the first-stage buffer stroke, enabling the connecting plate 4 to make a certain range of free displacement in the initial stage, effectively absorbing high-frequency, low-amplitude vibrations. Simultaneously, when the impact load increases and the displacement of the connecting plate 4 reaches the limit of the buffer gap, the buffer cylinder 5 contacts the connecting plate 4 and provides a second-stage buffer through its own elastic deformation. This achieves a multi-stage nonlinear buffering effect from soft to hard, avoiding rigid impacts and providing excellent limiting protection for the entire shock absorption system and the protected equipment.

[0036] Specifically, this embodiment provides the following technical solution by way of example: the bottom surface of the battery box 200 is square and has four corners, and the number of shock-absorbing components 100 is four, with each of the four shock-absorbing components 100 corresponding to one of the four corners.

[0037] Optionally, the elastic element is a compression spring.

[0038] Optionally, to achieve axial limiting of the connector 2, the connector 2 includes a head and a connecting part. The connecting part is vertically fixedly connected to the head, the outer diameter of the head is larger than the outer diameter of the connecting part, the connecting part slides through the top end of the support cylinder 3 and is connected to the battery box 200, and the head abuts against one end of the elastic member. Specifically, the connector 2 is inverted T-shaped.

[0039] In this embodiment, the connector 2 is a bolt, which is fixedly installed by a self-locking nut. The anti-loosening characteristic of the self-locking nut ensures that the connection between the shock-absorbing component 100 and the battery box 200 is always reliable, avoiding the risk of displacement of the shock-absorbing component 100, failure of the entire shock-absorbing system, or even secondary vibration (shaking) due to the failure of the fixing point, which greatly improves the safety and durability of the system.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
