Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to a mounting bracket of a battery pack and a vehicle. Background Art

[0002] When a new energy vehicle is involved in a head-on collision, the subframe and the body will be squeezed, the bending of the front beam of the subframe will cause the entire vehicle to move backward, and the rear mounting point of the subframe will be squeezed with the kickdown component of the body, thus deforming the mounting point of the battery pack and causing the battery pack to be squeezed and deformed. As the materials of existing battery packs are mainly lithium iron phosphate and ternary lithium, both of which have different collision deformation requirements, if the deformation of the battery pack is too large, the probability of the battery pack catching fire will increase.

[0003] Existing battery packs are usually installed on the vehicle body through a bracket with an anti-collision function to improve the safety performance of the battery pack. However, the existing bracket is large in size and the installation space of the battery pack is relatively small, which can easily cause the bracket to interfere with other parts of the car.

[0004] Therefore, it is urgent to design a bracket with simple structure and small space to install the battery pack. Summary of the invention

[0005] Based on this, the utility model provides a mounting bracket for a battery pack and a vehicle.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a car, which includes a battery pack 10, and the battery pack 10 is assembled to a kickdown component 40 through a mounting bracket. The kickdown component 40 of this embodiment is specifically arranged between the front cabin and the floor of the car. Since the installation position of the kickdown component is the prior art, this embodiment will not repeat the connection structure of the kickdown component with the front cabin and the floor.

[0029] See Figure 3The mounting bracket of this embodiment includes an anti-collision bar 20, which is horizontally placed in front of the battery pack 10 and fixedly attached to the front side wall of the battery pack 10. When the front of the car is deformed by a collision, the collision load will be transmitted to the battery pack 10 through the anti-collision bar 20. The anti-collision bar 20 can disperse the collision load along the axial direction of the anti-collision bar 20 and then transmit it to the battery pack 10, avoiding local concentrated force on the battery pack 10, helping to prevent the battery pack 10 from being deformed, and thus improving the safety of the battery pack 10.

[0030] The anti-collision bar 20 of this embodiment is preferably made of steel. The anti-collision bar 20 made of steel has strong toughness, high structural reliability, is suitable for bearing impact and dynamic loads, can effectively absorb the collision load of the vehicle, and improves the protection performance of the battery pack 10. The anti-collision bar 20 is provided with an avoidance hole 21, which allows the wiring harness of the battery pack 10 to extend to the outside for easy wiring.

[0031] The mounting seats 30 are fixedly arranged at both ends of the anti-collision bar 20 of this embodiment, and the mounting seats 30 are attached to the front surface of the anti-collision bar 20. The bottom of the mounting seats 30 overlaps the kickdown component 40. The mounting seats 30 are vertically provided with mounting grooves 31, and the bottom of the mounting grooves 31 is provided with through holes 33, and bolts are passed through the through holes 33 to connect the kickdown component 40. The mounting bracket of this embodiment can effectively improve the safety of the battery pack 10, has a simple structure, and occupies a small space.

[0032] The front side wall of the mounting seat 30 of this embodiment preferably includes a slope 32 tilted backward, and the slope 32 extends to the top of the mounting seat 30, so that the distance from the top to the bottom of the mounting seat 30 protruding from the anti-collision bar 20 gradually increases, and the mounting seat 30 is in a shape with a small top and a large bottom. The slope 32 is designed on the front side wall of the mounting seat 30. The slope 32 not only leaves a large space above the mounting seat 30 to avoid interference between the mounting seat 30 and the wiring harness and / or pipeline above it, but also enables the bottom of the mounting seat 30 to have a large area to contact the kickdown component 40, thereby ensuring the stability of the connection between the mounting seat 30 and the kickdown component. In addition, the designed slope 32 can cut off the side wall facing forward of the mounting groove 31, so that the bottom of the mounting groove 31 is exposed to the outside, which is convenient for bolts to be inserted into the through hole 33. It should be noted that the inclination angle and area of ​​the slope 32 can be designed according to actual needs. The bottom of the slope 32 of this embodiment is flush with the bottom of the mounting groove 31, so that the bottom of the mounting groove 31 is fully displayed. In some embodiments, the entire front side wall of the mounting seat 30 may be designed to be a sloped surface 32 .

[0033] The mounting seat 30 of this embodiment is preferably a cast aluminum part, which has sufficient hardness and can produce a large collapse to fully absorb energy after being subjected to a collision load. The steel anti-collision bar 20 is used in conjunction with the aluminum mounting seat 30 to effectively improve the anti-collision ability of the anti-collision structure for the battery pack 10.

[0034] The kickdown member 40 of the present embodiment is preferably in an inverted triangular shape, with one of the tip portions of the kickdown member facing downward and the other two tip portions facing both sides, so that the top of the kickdown member has a supporting plane 41 to support the mounting seat 30, and a first mounting hole is provided on the supporting plane 41 corresponding to the through hole 33 on the mounting seat 30 for passing a bolt, and the bolt connecting the kickdown member 40 and the mounting seat 30 can pass through the first mounting hole to ensure that the mounting seat 30 and the kickdown member are firmly installed.

[0035] A second mounting hole 42 is provided on the front surface of the kickdown member 40 of this embodiment, and a bolt is passed through the second mounting hole 42 to connect the subframe. A third mounting hole 43 is also provided on the support plane 41 of the kickdown member 40. The third mounting hole 43 is closer to the outside of the battery pack 10 than the first mounting hole, so that the bolt is passed through the third mounting hole 43 to connect the front suspension. It should be noted that the subframe and the front suspension are conventional structures of the automobile body, and are not described in detail in this embodiment.

[0036] The kickdown component 40 of the present embodiment is preferably formed by bending a sheet metal. The bent sheet metal forms a cavity inside the kickdown component, so that the kickdown component has a better energy absorption effect.

[0037] It should be noted that the battery pack 10 and the anti-collision bar 20, and the anti-collision bar 20 and the mounting seat 30 of this embodiment can be fixed by welding. Some embodiments can also be connected by conventional means such as bolts and bonding according to needs.

[0038] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
