[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] Figure 1 and Figure 2 As shown, an integrated lithium battery housing bracket includes a housing 5 and an upper cover 2 and a lower housing 3 located at both ends of the housing 5. An anti-collision layer 1 is fixedly connected to the outside of the housing 5. The anti-collision layer 1 is made of hard steel and can prevent the housing 5 from being directly damaged by collision. This design plays a role in protecting the housing 5. There is a gap 11 between the anti-collision layer 1 and the housing 5 to avoid collision between the anti-collision layer 1 and the housing 5 during collision. The gap 11 can play a buffering role to prevent the force applied to the anti-collision layer 1 from being directly transmitted to the housing 5, which further plays a protective role.

[0026] Figure 2-Figure 5As shown, a plurality of support rods 9 are fixedly connected in the gap 11, both ends of the support rods 9 are bent downward and the center points of the support rods 9 are in contact with the inner wall of the anti-collision layer 1 to form a vertex 14, and the vertex 14 coincides with the midpoint of the plane where the point is located, and both ends of the support rods 9 are fixedly connected to the side walls of the outer shell 5, and two support rods 9 are arranged on one side wall of the same outer shell 5, and the support rods 9 on the same surface are cross-arranged. By arranging the support rods 9, the anti-collision layer 1 can be supported, so that the anti-collision layer 1 is prevented from sinking inward after being hit and causing the gap 11 to decrease, thereby improving the anti-collision effect, and a triangle is formed between each support rod 9 and the side wall of the outer shell 5. Since the triangle is stable, the supporting effect of the support rods 9 can be better.

[0027] Figure 2 and Figure 3 As shown, each support rod 9 is sleeved with a shock-absorbing spring 10, and each support rod 9 is fixedly connected to two limit blocks 12, and the shock-absorbing spring 10 is located between the two limit blocks 12. By arranging the shock-absorbing spring, when the anti-collision layer 1 is hit, the support rod 9 transmits part of the force, and in the process of the support rod 9 transmitting the force, the shock-absorbing spring 10 is deformed and shaken due to the force, thereby dispersing part of the force, thereby reducing the force and achieving a shock-absorbing effect, further protecting the shell 5, and the limit blocks 12 limit the range of movement of the shock-absorbing spring 10 to prevent the shock-absorbing spring 10 from sliding on the support rod 9.

[0028] Figure 2-Figure 5 As shown, a reinforcement rod 6 is fixedly connected below each vertex 14 in the gap 11 to support the support rod 9 .

[0029] Figure 2-Figure 5 As shown, the reinforcing rod 6 is provided with a shock absorbing spring 13, so when the reinforcing rod 6 transmits the force, the shock absorbing spring 13 shakes, thereby dispersing part of the force to prevent a larger force from damaging the outer shell 5, thereby playing a shock absorbing role and protecting the outer shell 5.

[0030] Figure 2-Figure 5 As shown, both ends of the gap 11 are connected to the outside world, so during assembly, the support rods 9 are assembled together in pairs, and the shock-absorbing spring 10 is sleeved on the support rods 9, and the limit blocks 12 are welded to the two ends of the shock-absorbing spring. Thereafter, the fixing rod is welded at the intersection of the two support rods 9, and the shock-absorbing spring 2 13 is sleeved on the reinforcement rod 6, and the assembled support rods 9 and the reinforcement rod 6 are further fixed to the side wall of the outer shell 5, and finally the anti-collision layer 1 is sleeved on the outside of the support rods 9 and fixed to complete the assembly. This design facilitates assembly.

[0031] Figure 2-Figure 5As shown, brackets 4 are integrally formed at both ends of the housing 5. The integrally formed brackets 4 can avoid additional installation of the brackets 4. This design simplifies the installation process.

[0032] Figure 2-Figure 5 As shown, a nickel sheet 8 is fixedly connected between the bracket 4 and the lower shell 3, and a fixing part 7 which can be inserted between the outer shell 5 and the lithium battery is provided on the nickel sheet 8. The fixing part 7 extends upward into the outer shell 5, and fixes the nickel sheet 8 between the bracket 4 and the lower shell 3 by friction, thereby avoiding the nickel sheet 8 from being fixed by welding, making the installation of the nickel sheet 8 more convenient and quick, and safer and easier to operate than the soldering fixation method. In addition, this design makes the nickel sheet 8 and the battery cell isolated by the outer shell 5, which can effectively avoid the occurrence of short circuits.

[0033] The above is an introduction to an integrated lithium battery housing bracket provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
