Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to an integrated battery module. Background Art

[0002] With the continuous development of the economy and advancement of new energy technologies, electrochemical energy storage products are becoming increasingly mature in the market. Battery modules are one of the electrochemical energy storage products.

[0003] However, the traditional battery module design has some shortcomings in terms of protection performance, heat dissipation efficiency and stability, as described below:

[0004] The protective structure of traditional battery modules is simple and has limited resistance to external shocks and vibrations, which can easily cause damage to battery components and even cause safety hazards.

[0005] The heat dissipation design of traditional battery modules is often limited to simple heat sinks or fans, which cannot effectively dissipate internal heat to the external environment, leading to problems such as battery overheating and shortened life.

[0006] Traditional battery modules have deficiencies in terms of cell assembly fixation and vibration control, which can easily cause collisions and damage between cell assemblies, affecting overall stability.

[0007] Since overheating caused by poor heat dissipation may pose a risk of battery fire, traditional designs cannot effectively address this safety hazard.

[0008] To this end, those skilled in the art provide an integrated battery module to solve the problems raised in the above background technology. Summary of the invention

[0009] In view of the deficiencies of the prior art, the present invention provides an integrated battery module, which solves the problems of the prior art in terms of protection performance, heat dissipation efficiency and stability.

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions: an integrated battery module, comprising a shell, a top cover is provided on the top of the shell, side protection blocks are provided on the left and right sides of the shell, front protection blocks are provided on the front and rear sides of the shell, a plurality of positioning rods are fixedly connected to the inner wall of the shell, a plurality of sliding sleeves are slidably connected to the outer wall of the positioning rod, a docking plate is rotatably connected to one side of the sliding sleeve, a contact block is fixedly connected to one side of the docking plate, a plurality of first dampers are fixedly connected to the inner wall of the shell, a plurality of springs are provided on the outer wall of the positioning rod, a first circulation fan is provided on one side of the shell, a second circulation fan is provided on one side of the shell, a plurality of heat dissipation pipes are fixedly connected to the input end of the first circulation fan, a protection box is slidably connected to the adjacent side of the plurality of contact blocks, a plurality of battery cell groups are installed on the inner wall of the protection box, an extension block is installed on the top of the battery cell group, shock absorbing components are provided on the upper and lower sides of the protection box, and an external component is provided on the top of the shell.

[0011] Preferably, the shock absorbing assembly includes a locking plate, a plurality of the locking plates are fixedly connected to the four corners of the bottom of the shell, a plurality of rotating buckles are fixedly connected to the adjacent sides of two of the locking plates, one side of the rotating buckle is rotatably connected to a connecting rod, a telescopic rod is provided on the adjacent sides of the two locking plates, a wrapping ring is slidably connected to the outer wall of the telescopic rod, a travel plate is fixedly connected to both sides of the wrapping ring, a second damper is fixedly connected to the inner wall of the travel plate, a plurality of second buffer pads are provided at the bottom of the top cover, and a first buffer pad is provided at the bottom of the second buffer pad.

[0012] Preferably, a handle is rotatably connected to the top of the top cover, and a plurality of connectors are provided on the top of the top cover, and one end of the connector is fixedly connected to a connecting wire.

[0013] Preferably, a plurality of side protection blocks are fixedly connected to the bottom of the top cover, and a plurality of front protection blocks are fixedly connected to the bottom of the top cover.

[0014] Preferably, the heat dissipation pipe passes through the outer shell and the protection box in sequence, and the heat dissipation pipe is fixedly connected to the output end of the second circulation fan.

[0015] Preferably, the epitaxial block is electrically connected to a connector, and the connector is electrically connected to a connecting wire.

[0016] Preferably, the connecting rod is fixedly connected to the output end of the second damper.

[0017] Preferably, a plurality of the locking plates are arranged at the bottom of the top cover, and a plurality of the locking plates are fixedly connected to the four bottom corners of the shell.

[0018] Preferably, a plurality of springs are arranged on both sides of the sliding sleeve.

[0019] Preferably, the side protection blocks and the front protection blocks are made of rubber.

[0020] Working principle: Existing integrated battery modules are widely used. When used in electric bicycles or mobile vehicles, the battery installed at the bottom of the bicycle is susceptible to external damage due to the changing riding conditions.

[0021] The front protection block and the side protection block can effectively protect the internal battery pack, reduce damage or battery leakage caused by edge scratches, and reduce the service life. When the battery pack swings, the contact blocks set on both sides of the interior can buffer the stress generated by the shaking through the sliding sleeve on the outer wall of the positioning rod and the cooperation between multiple springs. In this process, the first damper is used to ensure the overall shock absorption stroke to prevent the battery from shaking too much and being unable to buffer.

[0022] The stress generated up and down is always kept stable by multiple second buffer pads and the first buffer pad. When the up and down shaking stress is too large, the locking plate will be pushed to squeeze the telescopic rod to slide inside the wrapping ring, and the connecting rod will be pushed to move during the sliding process, thereby cooperating with the setting of the second damper to achieve multi-level buffering.

[0023] In order to reduce the heat generated inside the battery cell during use, the first circulation fan and the second circulation fan will continuously remove the air inside the protective box through the heat dissipation pipe during use, effectively improving the heat dissipation efficiency through replacement.

[0024] The present invention provides an integrated battery module having the following beneficial effects:

[0025] 1. The present invention can effectively improve the anti-deformation effect of the integrated battery module by using the side protection block, the front protection block, the first damper, the contact block and other components in combination, and reduce the damage to the internal battery cell group caused by the deformation of the edge of the shell due to collision and extrusion.

[0026] 2. The present invention can effectively improve the internal heat dissipation effect and increase the service life of the battery module through the coordinated use of the first circulation fan, the second circulation fan, the heat dissipation pipe, the protection box and other components.

[0027] 3. The present invention can improve the anti-puncture and anti-vibration performance of the battery module, reduce the risk of fire, and ensure safety in use through the coordinated use of components such as the protection box, the wrapping ring, the second buffer pad, and the first buffer pad.
