Description

Technical Field

[0001] This utility model relates to the field of vehicle battery technology, specifically to a shock-resistant battery rack assembly. Background Technology

[0002] With the development of new energy vehicle technology, hybrid heavy-duty trucks have been widely used due to their advantages in power and economy. As the core component of hybrid heavy-duty trucks, the installation stability of the battery pack directly affects the vehicle's safety and battery lifespan. Heavy-duty trucks face complex operating conditions during long-distance transportation, such as bumpy roads, sharp turns, and emergency braking, generating multi-directional vibrations and impacts far greater than those in ordinary passenger cars. Currently, traditional battery racks are mostly rigid load-bearing plate structures, which not only make the connectors prone to loosening under long-term vibration, but also lack effective constraints to cope with large lateral forces, posing safety hazards. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model proposes an anti-vibration battery rack assembly, which can improve the anti-vibration performance of the battery rack.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a shock-resistant battery rack assembly, comprising a battery rack and shock-resistant connectors; The battery rack includes a support plate and connecting columns. There are two support plates, one at the top and one at the bottom. The upper support plate is fixedly connected to the vehicle chassis. The two support plates are connected by multiple connecting columns, forming an overall cage structure. The seismic connection includes bolts and elastic washers. The bearing plate and the connecting column have interconnected threaded holes. The bolts are threadedly connected to the threaded holes, and the elastic washers are sleeved on the bolts.

[0005] The upper support plate is used to fix it to the vehicle chassis. The upper and lower support plates are connected by connecting columns to form a cage structure, which houses the battery module. The connecting columns and support plates are connected by bolts. Elastic washers can absorb vibration energy, reduce the amplitude at the bolt connection, and the elastic force of the bolts under the action of the elastic washers increases the friction of the threaded connection, further improving the shock resistance.

[0006] The beneficial effects of the above-mentioned anti-vibration battery rack assembly are: the cage structure has good load-bearing strength and rigid support effect, and the elastic gasket can effectively prevent the loosening of bolt connections, thereby improving the anti-vibration performance of the battery rack.

[0007] Furthermore, the bearing plate is an aluminum alloy hollow plate with multiple longitudinal reinforcing ribs inside and a honeycomb cross-section.

[0008] Using aluminum alloy hollow honeycomb panels as the load-bearing plate, the honeycomb structure has a dense support structure, which can improve the bending and torsional stiffness of the plate, and while ensuring the strength of the battery rack, it also has the advantage of being lightweight.

[0009] Furthermore, the gasket is a polyurethane gasket.

[0010] Polyurethane not only has high elasticity, but also good wear resistance, pressure resistance and aging resistance.

[0011] Furthermore, shock-absorbing pads are provided on the inner sides of both the bearing plate and the connecting column.

[0012] The shock-absorbing pads can act as a buffer for the battery modules on the inside of the battery rack, preventing the battery modules from directly colliding rigidly with the battery rack and thus better protecting the battery modules.

[0013] Furthermore, it also includes a restraint mechanism, including pull rods, a plurality of which are arranged around the periphery of the battery rack, with one end fixedly mounted on the bottom of the vehicle and the other end connected to each connecting post.

[0014] By using multiple tie rods arranged circumferentially, lateral tension can be provided when the battery rack is subjected to lateral force, thus providing lateral constraint to the battery rack and greatly improving its stability.

[0015] Furthermore, the constraint mechanism also includes a second tie rod, and an ear plate is provided on the edge of the lower bearing plate. One end of the second tie rod is fixedly mounted on the vehicle chassis, and the other end is connected to the ear plate.

[0016] Since the lower support plate carries the battery module, it can be held in place by the second tie rod when subjected to lateral force, which further improves the overall integrity and stability of the battery rack. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 This utility model provides a shock-resistant battery rack assembly, including a battery rack 10 and a shock-resistant connector 20. The battery rack 10 includes a support plate 11 and connecting columns 12. There are two support plates 11, one above the other. The upper support plate 11 is fixedly connected to the vehicle chassis and connected to the lower support plate 11 through multiple connecting columns 12, forming an overall cage structure. The shock-resistant connector 20 includes bolts 21 and elastic washers 22. The support plate 11 and the connecting columns 12 have interconnected threaded holes and are threadedly connected by bolts 21. The elastic washers 22 are sleeved on the bolts 21.

[0021] The upper support plate 11 is used to fix the battery rack 10 to the vehicle chassis. The upper and lower support plates 11 are connected by the connecting column 12 to form a cage structure, which is used to house the battery module. It has good load-bearing strength and rigid support effect. The connecting column 12 and the support plate 11 are connected by bolts 21. The elastic washer 22 can absorb vibration energy during vibration to reduce the amplitude at the bolt connection and prevent the bolt 21 from slipping. Under the elastic force of the elastic washer 22, the bolt 21 can continuously increase the friction of the threaded connection, further improving the anti-vibration and anti-loosening effect, thereby improving the anti-vibration performance of the battery rack 10.

[0022] In this embodiment, the support plate 11 is a high-strength aluminum alloy hollow plate, and the gasket is a polyurethane gasket. The high-strength aluminum alloy hollow plate has multiple longitudinal reinforcing ribs inside, and its cross-section is honeycomb-shaped. Using a high-strength aluminum alloy hollow honeycomb plate as the support plate 11 provides a dense support structure, improving the bending and torsional stiffness of the plate and ensuring the strength of the battery rack 10 while also being lightweight. The gasket is made of polyurethane, which not only has high elasticity but also good wear resistance, pressure resistance, and aging resistance.

[0023] Both the inner sides of the support plate 11 and the connecting column 12 are provided with shock-absorbing pads. The shock-absorbing pads can act as a buffer for the battery module inside the battery rack 10, preventing the battery module from directly colliding rigidly with the battery rack 10, and thus better protecting the battery module.

[0024] Specifically, it also includes a restraint mechanism, including a tie rod 31 and a tie rod 32. Multiple tie rods 31 are arranged around the battery rack 10, with one end fixedly mounted on the bottom of the vehicle and the other end connected to each connecting post 12. The lower support plate 11 has an ear plate 111 on its edge. One end of the tie rod 32 is fixedly mounted on the vehicle chassis, and the other end is connected to the ear plate 111.

[0025] The multiple tie rods 31 arranged circumferentially can provide lateral tension when the battery rack 10 is subjected to lateral force, thus providing lateral constraint to the battery rack 10 and greatly improving its stability. Furthermore, since the lower support plate 11 carries the battery module, when subjected to lateral force, the tie rod 32 can hold the lower support plate 11 in place, further improving the overall integrity and stability of the battery rack 10.

[0026] The working principle of the aforementioned shock-resistant battery rack assembly is as follows: the upper support plate 11 is fixed to the vehicle chassis, and the support plate 11 is connected to the connection via bolts 21, forming a cage-like battery rack 10. The battery modules are located inside the battery rack 10. The elastic pad 22 can continuously increase the friction force of the threaded connection through its elasticity and can absorb vibration energy during vibration. The tie rods 31 and 32 can provide lateral tension when the battery rack 10 is subjected to lateral force.

[0027] Using the aforementioned anti-vibration battery rack assembly, its cage structure exhibits good load-bearing strength and rigid support. Furthermore, the elastic gaskets reduce vibration at bolted connections to prevent bolt slippage and continuously increase friction in threaded connections, further enhancing the anti-vibration effect. The tie rods provide lateral restraint, further improving the stability of the battery rack.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
