Description

Technical Field

[0001] This utility model belongs to the technical field of shock absorption mechanism, and specifically relates to a shock absorption mechanism for lithium battery packs. Background Technology

[0002] In practical applications, especially in electric vehicles, drones, or other environments that require frequent vibration, lithium battery packs may be affected by external impacts or vibrations. Vibration may cause electrode materials inside the lithium battery to fall off, separators to break, or electrolytes to leak, thereby affecting battery performance and even causing safety hazards. Therefore, shock absorption mechanisms are needed to dampen the lithium battery packs.

[0003] Most existing shock absorption mechanisms dampen the lithium battery by inserting a soft material between the lithium battery and the base plate, and then fastening the lithium battery to the base plate with bolts. However, in this method, the soft material usually has low thermal conductivity, which may hinder the heat dissipation of the battery pack. In the existing technology, it is usually necessary to add heat dissipation components to the shock absorption mechanism to dissipate heat from the lithium battery, which increases the production and maintenance costs of the equipment. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a lithium battery pack shock absorption mechanism, which not only absorbs the shock of the lithium battery pack during use, but also dissipates heat from the lithium battery pack through heat dissipation grooves on the bottom and side walls of the support frame during the shock absorption process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a lithium battery pack shock absorption mechanism, including a mounting box, a support frame slidably disposed inside the mounting box, a shock absorption mechanism disposed between the mounting box and the support frame, the shock absorption mechanism including a fixed block disposed in the middle of the bottom of the mounting box, both ends of the fixed block being rotatably and slidably connected to sliders, shock absorbers being disposed between the sliders and adjacent side walls of the mounting box, rotating plates being connected to the opposite side surfaces of the sliders via rotating seats one, symmetrically provided sliding grooves at the lower end of the support frame, rotating seats two being slidably disposed inside the sliding grooves via sliding members, the sliding members including sliding rods disposed inside the sliding grooves, the upper ends of rotating seats two being slidably connected to the sliding rods respectively, and the ends of the rotating plates away from rotating seats one being rotatably connected to adjacent rotating seats two respectively.

[0006] As a further improvement of this utility model, the shock absorber includes a spring disposed between the slider and the adjacent mounting box sidewall, one end of the spring being connected to the inner sidewall of the slider, and the other end being connected to the inner sidewall of the mounting box.

[0007] As a further improvement of this utility model, several telescopic columns are evenly arranged at the bottom of the mounting box, the telescopic ends of the telescopic columns are connected to the bottom of the support frame, and a mounting plate is fixedly welded to the bottom of the mounting box, with mounting holes evenly opened around the perimeter of the mounting plate.

[0008] As a further improvement of this utility model, the support frame is provided with a placement cavity, and a lithium battery pack is placed inside the placement cavity. Several anti-collision pads are evenly bonded on the side wall of the placement cavity, and heat dissipation grooves are provided on the side wall and bottom of the placement cavity.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by incorporating shock-absorbing components, when external vibrations occur, the support frame moves downwards under gravity, which in turn pushes the rotating plate to rotate. The rotating plate then pushes the sliding plate to move to both sides of the mounting box, compressing the spring. The spring generates a counter-force, stabilizing the sliding plate and thus the support frame, thereby stabilizing the lithium battery pack. This reduces the risk of poor contact or disconnection with external circuits due to vibration. Furthermore, during the shock absorption process, the heat dissipation grooves on the bottom and side walls of the support frame can effectively dissipate heat from the lithium battery pack.

[0011] Secondly, by setting up anti-collision pads, the impact force of the placement cavity sidewall on the lithium battery pack can be absorbed and dispersed, further reducing the impact of vibration on the battery pack and improving equipment safety.

[0012] Thirdly, by setting telescopic columns, which are located around the support frame and can move up and down with the support frame, they can provide auxiliary support for the support frame.

[0013] Fourth, the bottom of the mounting box is fixedly connected to a mounting plate, and mounting holes are evenly opened around the perimeter of the mounting plate. The mounting holes can be firmly connected to the external structure by bolts or other fasteners, which effectively prevents the mounting box from shifting due to vibration or impact during transportation or use, and ensures that the lithium battery pack is always kept in the predetermined position.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown in Figure 3, a shock-absorbing mechanism for a lithium battery pack includes a mounting box 101. A support frame 102 is slidably mounted inside the mounting box 101. A shock-absorbing mechanism is provided between the mounting box 101 and the support frame 102. The shock-absorbing mechanism includes a fixing block 201 located at the center of the bottom of the mounting box 101. Sliding blocks 202 are rotatably and slidably connected to both ends of the fixing block 201. Shock-absorbing components are provided between the sliding blocks 202 and adjacent side walls of the mounting box 101. The shock-absorbing components include those provided on the sliding blocks 202. A spring 204 is connected to the side wall of the adjacent mounting box 101. One end of the spring 204 is connected to the inner side wall of the slider 202, and the other end is connected to the inner side wall of the mounting box 101. A rotating plate 203 is connected to the opposite side of the slider 202 through a rotating seat 103. A sliding groove is symmetrically opened at the lower end of the support frame 102. A rotating seat 204 is slidably arranged inside the sliding groove through a sliding member. The end of the rotating plate 203 away from the rotating seat 103 is rotatably connected to the adjacent rotating seat 204.

[0022] like Figure 3 As shown, the sliding member includes a slide rod 105 disposed inside the slide groove, and the upper end of the rotary seat 104 is slidably connected to the slide rod 105.

[0023] like Figure 2 As shown, several telescopic columns 205 are evenly arranged at the bottom of the mounting box 101, and the telescopic ends of the telescopic columns 205 are connected to the bottom of the support frame 102.

[0024] like Figure 1 , 4As shown, the support frame 102 has a placement cavity inside, and the lithium battery pack 206 is placed inside the placement cavity. The side walls and bottom of the placement cavity are provided with heat dissipation grooves 303. The heat dissipation grooves 303 are in contact with the outside air, which can increase the air circulation path and help heat to be transferred from the battery pack to the external environment more quickly, thereby effectively reducing the operating temperature of the battery pack and preventing overheating, so as to improve the charging and discharging efficiency and cycle life of the battery.

[0025] like Figure 1 As shown, a mounting plate 301 is fixedly connected to the bottom of the mounting box 101. Mounting holes 302 are evenly provided around the mounting plate 301. The mounting holes 302 can be firmly connected to the external structure by bolts or other fasteners to ensure that the mounting box 101 will not be displaced during transportation or use.

[0026] In use, the mounting box 101 is fixedly connected to the external structure through the mounting hole 302 with bolts. Then, the lithium battery pack 206 is placed inside the placement cavity of the support frame 102. During the use of the lithium battery pack 206, external bumps and vibrations may occur. The shock absorption mechanism can reduce the vibration of the mounting box 101. When external bumps and vibrations occur, the support frame 102 will move downward under the action of gravity, which will push the rotating plate 203 to rotate. The rotating plate 203 pushes the sliding plate to move to both sides of the mounting box 101, which will compress the spring 204. The spring 204 will generate a counter-force, making the sliding plate tend to stabilize, thereby stabilizing the support frame 102. This reduces the shaking amplitude of the lithium battery pack 206 inside the support frame 102, helps maintain the stability of the connection between the battery and the external circuit, and prevents poor contact or open circuit problems caused by loosening.

[0027] According to another embodiment of the present invention, such as Figure 4 As shown, several anti-collision pads 207 are evenly arranged on the side wall of the placement cavity. The anti-collision pads 207 can absorb and disperse the impact force of the side wall of the placement cavity on the lithium battery pack 206, further reducing the impact of vibration on the battery pack.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
