A design structure for a battery limiting pressure plate

Abstract

This application discloses a design structure for a battery limiting pressure plate, relating to the field of battery limiting pressure plate technology. It includes a fixing component comprising a fixing base, a protective shell, and a wire-passing hole. The fixing component provides protection. The fixing base is cuboid in shape, and its installation direction is parallel to the vehicle's central axis. The fixing base has a limiting hole, which is cylindrical in shape and its installation direction is perpendicular to the fixing base. This design achieves two main benefits: firstly, by changing the shape of the shock absorber, the contact area between the shock absorber and the pressure plate is increased, enhancing its shock absorption and buffering capacity, thus improving the battery pack's fixing effect; secondly, by changing the structure of the shock absorber, the deformation of the airbag can increase the contact area with the pressure plate, improving the shock absorption effect on the battery pack. Furthermore, the material near the pressure plate is a rigid material, further improving the stability of the battery pack.

Description

Technical Field

[0001] This invention relates to the field of battery limiting pressure plate technology, and in particular to a design structure for a battery limiting pressure plate. Background Technology

[0002] Electric vehicles refer to cars that use electricity as a power source and are driven by an electric motor. They belong to new energy vehicles and include pure electric vehicles, hybrid electric vehicles, and fuel cell electric vehicles. The power system of electric vehicles comes from batteries.

[0003] In existing technologies, the shock absorption effect is achieved through the spheres inside the first, second, third, and fourth shock-absorbing balls. However, when in use, the spheres are made of rubber, and when subjected to pressure for a long time, if the pressure is too high and the spheres reach their pressure limit, they are prone to damage. The contact area between the spheres and the upper and lower balance plates is small. During use, the smaller the contact area, the worse the shock absorption effect.

[0004] For example, Chinese patent CN112670644A provides a mechanical safety protection device for the power system of a new energy vehicle. The battery pack is placed between a support plate and a pressure plate. The bottom of the support plate is provided with multiple sets of first shock-absorbing balls, multiple sets of second shock-absorbing balls are provided between the support plate and the battery, multiple sets of fourth shock-absorbing balls are provided between the battery and the pressure plate, and multiple sets of third shock-absorbing balls are provided between the pressure plate and the cover. The battery pack is flexibly installed in the battery box to improve its shock resistance and enhance the safety protection of the battery.

[0005] It has significant drawbacks: during use, the ball is made of rubber, and when subjected to pressure for a long time, it is prone to damage when the pressure is too high and the ball reaches its limit. At the same time, the contact area between the ball and the upper and lower balance plates is small. The smaller the contact area, the worse the shock absorption effect. Summary of the Invention

[0006] This application provides a battery limiting pressure plate design structure, which solves the problem in the prior art where the ball alone provides shock absorption, resulting in poor shock resistance and potential damage to the ball after prolonged use. Furthermore, the small contact area between the ball and the upper and lower balance plates contributes to poor shock resistance. This solution allows for the modification of the shape and material of the shock-absorbing block to provide shock absorption and buffering for the battery pack, thereby improving the battery's shock resistance during operation.

[0106] The cavity of the damping block 510 protrudes towards the axis of the damping block 510, and the outer ring of the damping block 510 protrudes away from the axis of the damping block 510.

[0107] The pressure plate 520 is cylindrical, and the installation direction of the pressure plate 520 is parallel to the fixed base 120.

[0108] The pressure plate 520 is fixed on the upper and lower sides of the shock absorber 510, and the pressure plate 520 is fixed at both ends of the axis of the shock absorber 510;

[0109] The pressure plate 520 at one end of the shock absorber 510 is fixed to the side away from the shock absorber 510 and to the two sides of the shock absorber pressure plate 540 parallel to the fixed base 120.

[0110] There are 15-25 pressure plates 520, which are evenly spaced.

[0111] It also includes a limiting component 200 and a battery pack 400. The limiting component 200 further includes a fixing rod 210, a nut 220, a limiting piece 230, a nut 240, and a limiting rod 250.

[0112] The limiting component 200 serves a supporting function;

[0113] The fixing rod 210 is cylindrical, and the installation direction of the fixing rod 210 is perpendicular to the fixing base 120.

[0114] The limiting rod 250 is cylindrical, and the axis of the limiting rod 250 is parallel to the axis of the fixing rod 210.

[0115] The fixing rod 210 is fixed in the limiting groove 340 by the limiting rod 250.

[0116] The second nut 240 is threaded onto the first fixing rod 210;

[0117] The limiting piece 230 is cylindrical and has a coaxial cavity. The installation direction of the limiting piece 230 is parallel to the fixed base 120. The limiting piece 230 is fixed to the fixed rod 210 through the coaxial cavity.

[0118] The installation height of the limiting piece 230 is higher than the installation height of the nut 240;

[0120] The nut 220 is threaded onto the fixing rod 210;

[0122] The shock-absorbing pressure plate 540 is fixed between the limiting piece 230 and the nut 240;

[0123] The battery pack 400 is fixed between two shock-absorbing components 500, and the pressure plate 520 near the battery pack 400 is fixed on the battery pack 400.

[0124] The fixing assembly 100 also includes a top cover 110 and bolts 150;

[0125] The top cover 110 is rectangular in shape, and the installation direction of the top cover 110 is parallel to the fixed base 120. The top cover 110 is fixed on the protective shell 130.

[0126] The top cover 110 has a through hole 111, which is cylindrical and the installation direction of the through hole 111 is perpendicular to the top cover 110.

[0127] The through holes 111 are four to six in number and are evenly spaced apart.

[0128] The end of the fixing rod 210 away from the limiting rod 250 is fixed by passing through the through hole 111;

[0129] The nut 220 is fixed above the top cover 110.

[0130] During installation, firstly, thread the fixing rod 310 of the limiting component 2 300 into the limiting hole 121 for fixation. Simultaneously, place the pressure plate 520 onto the fixing rods 310 and thread the nut 330 onto the fixing rods 310. Place the battery pack 400 on the shock-absorbing component 500 below. Then, pass the fixing rod 210 of the limiting component 200 through the through hole 111, and thread the nut 220 onto the upper end of the fixing rod 210. Another shock-absorbing component 500 has a pressure plate 520 that passes through the lower side of the fixing rod 210 of the limiting component 200 for fixation. Nut 240 is threaded to the lower side of the fixing rod 210. After the component is completed, the top cover 110 is placed on the protective shell 130, so that the shock-absorbing component 500 fixed on the limiting component 200 is fixed above the battery pack 400 to fix the battery. The top cover 110 is fixed to the protective shell 130 by one end of the bolt 150.

[0131] The shock absorber 510 is made of rubber. When subjected to pressure, the shock absorber 510 uses its own elasticity to achieve a shock-absorbing effect, thereby improving the shock resistance of the battery pack 400. At the same time, compared with the existing technology, the contact area between the shock absorber 510 and the pressure plate 520 is increased, thus enhancing its shock-absorbing capacity.

[0132] Example 2

[0133] In Example 1, the shock absorption effect of the shock absorber 510 is poor. During vehicle operation, while the shock absorber 510 is providing shock absorption, it may also create a rigid connection between the battery pack 400 and the protective shell 130, resulting in poor battery protection and inadequate shock absorption. To address these issues, the solution in Example 1 is further improved, such as... Figure 6-9 As shown:

[0134] The damping block 510 is divided into two equal parts by its cross-section parallel to the maximum diameter of the damping plate 540. The damping block 510 near the damping plate 540 is made of phenolic resin.

[0135] The shock-absorbing block 510, which is far away from the shock-absorbing pressure plate 540, is a soft bladder made of latex material. When the soft bladder is compressed, it expands outward, increasing the contact area with the pressure plate 520.

[0136] During its use, the material of the shock absorber 510 near the pressure plate 520 is a rigid material, while the end away from the pressure plate 520 is an airbag. During its use, the airbag can improve the buffering force on the battery pack 400, while the rigid material near the pressure plate 520 can improve stability. During use, the pressure plate 520 near the airbag is subjected to pressure, which acts on the airbag, causing it to deform. At the same time as deformation, the contact area between the airbag and the pressure plate 520 increases, and the shock absorber 510 can provide better shock absorption.

[0137] When in use, the structure of the shock absorber 510 is changed, and the deformation of the airbag can increase the contact area with the pressure plate 520, which can improve the shock absorption effect on the battery pack 400. The material near the pressure plate 520 is a hard material, which can further improve the stability effect.

[0138] Example 3

[0139] In Example 2, the installed soft capsule must be constantly secured to the battery pack 400. After prolonged use, the soft capsule deforms more, reducing its elasticity and cushioning / shock absorption capacity. To address these issues, the solution in Example 2 is further improved, such as... Figure 10-13 As shown:

[0140] The shock absorption assembly 500 also includes a protective bladder 530;

[0141] The protective bladder 530 is annular, and one end of the protective bladder 530 is fixed to the outside of the soft bladder inside the shock absorber 510.

[0142] The protective bladder 530 is fixed at one end away from the soft bladder and is fixed on the pressure plate 520 near the shock-absorbing pressure plate 540. The diameter of the protective bladder 530 fixed on the pressure plate 520 near the shock-absorbing pressure plate 540 is larger than the diameter of the protective bladder 530 fixed on the soft bladder.

[0143] The protective bladder 530 is made of latex. When the soft bladder is compressed and expands, it squeezes the protective bladder 530 outward, thereby increasing the contact area between the protective bladder 530 and the pressure plate 520.

[0144] When in use, the protective bladder 530 added to the outside of the shock absorber 510 can be connected to the air bladder. The protective bladder 530 can distribute the pressure on the air bladder and fix the shape of the upper soft bladder to prevent it from deforming too much. When subjected to pressure, the protective bladder 530 deforms and its contact area with the pressure plate 520 increases, thus improving stability and shock absorption.

[0145] When in use, the installation of the protective bladder 530 can distribute the pressure on the soft bladder, fix the shape of the soft bladder, achieve a protective effect, and improve the service life of the airbag. At the same time, the protective bladder 530 generates greater deformation, increases the contact area with the pressure plate 520, and has a better shock absorption and cushioning effect.

For those skilled in the art, the present invention can have various modifications and variations.
