Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a pressure-resistant battery. Background Technology

[0002] In the modern energy sector, batteries, as crucial energy storage devices, are widely used in numerous industries such as consumer electronics, electric vehicles, and aerospace. Traditional batteries typically use conventional casings to encapsulate electrodes and electrolytes, and their structural design is primarily geared towards conventional environments, capable of meeting the power supply needs of most devices under normal pressure conditions.

[0003] However, when batteries are used in special scenarios such as deep-sea exploration, underground exploration, and high-pressure industrial equipment, the casing of ordinary batteries is easily deformed or even cracked due to the enormous external pressure. Internal components can also be damaged by compression, leading to battery leakage, short circuits, and malfunction, severely limiting the application and development of related equipment in extreme environments. Therefore, there is an urgent need to design a pressure-resistant battery to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant battery to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pressure-resistant battery includes a protective component, the protective component including a housing, the housing having a groove layer inside, and the groove layer having a pressure-resistant layer inside;

[0007] The bottom of the protective component is slidably connected to a fixing component, which includes a battery cover. A reinforcing rib is provided on one side of the battery cover, and several buffer grooves are distributed around the reinforcing rib. The housing is connected to the battery cover by bolts.

[0008] Preferably, a liquid injection assembly is provided on one side of the battery cover, and mounting assemblies are provided on both sides of the liquid injection assembly. The mounting assembly includes a terminal post that is sleeved on the battery cover, and a sealing adhesive is provided at one end of the terminal post.

[0009] Preferably, buffer pads are provided on both sides of the housing, and the buffer pads are used at least for cushioning the housing.

[0010] Preferably, the compressive layer has a honeycomb structure, each cell of the honeycomb structure is a regular hexagon, and the side length of the regular hexagon is 3-5mm and the wall thickness is 0.5-1mm.

[0012] Preferably, a groove is provided on one side of the sealing adhesive, and the groove is at least used to prevent battery fluid from creeping into the alkali.

[0013] In the above technical solution, the pressure-resistant battery provided by this utility model has the following beneficial effects:

[0014] (1) The sliding groove layer inside the shell of the protective component, together with the honeycomb buffer groove around the reinforcing rib of the battery cover of the fixed component, forms a three-dimensional buffer structure. The unique hexagonal cell design of the honeycomb buffer groove can evenly distribute the pressure to each side wall when subjected to external pressure, effectively avoiding local stress concentration.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown in the figure, the present invention provides a pressure-resistant battery, including a protective component 1. The protective component 1 includes a housing 11, and a sliding groove layer 12 is provided inside the housing 11. A pressure-resistant layer 13 is provided inside the sliding groove layer 12. A fixing component 2 is slidably connected to the top of the protective component 1. The fixing component 2 includes a battery cover 21. A reinforcing rib 22 is provided on one side of the battery cover 21. A plurality of buffer grooves 23 are distributed around the reinforcing rib 22. The housing 11 is connected to the battery cover 21 by bolts.

[0024] In this embodiment, a protective component 1 is included. The protective component 1 includes a housing 11. A groove layer 12 is provided inside the housing 11. A pressure-resistant layer 13 is provided inside the groove layer 12. The housing 11 of the protective component 1 has a rectangular box-shaped structure and a three-layer structure inside: the outermost layer is the housing 11 made of aluminum alloy, the middle layer is the groove layer 12 arranged circumferentially along the inner wall of the housing 11, and the innermost layer is the pressure-resistant layer 13 embedded inside the groove layer 12.

[0025] The bottom of the protective component 1 is slidably connected to a fixing component 2, which includes a battery cover 21. A reinforcing rib 22 is provided on one side of the battery cover 21, and several buffer grooves 23 are distributed around the periphery of the reinforcing rib 22. The housing 11 is connected to the battery cover 21 by bolts. A cross-shaped arrangement of reinforcing ribs 22 is vertically welded to the upper surface of the battery cover 21. The height of the reinforcing ribs 22 is 1.2-1.5 times the thickness of the battery cover 21, forming a support frame for the battery module. The interior can be filled with polyurethane foam cushioning material.

[0026] Specifically, a liquid injection assembly 4 is provided on one side of the battery cover 21, and mounting assemblies 3 are provided on both sides of the liquid injection assembly 4. The mounting assemblies include terminal posts 31 that are sleeved on the battery cover, and a sealing adhesive 32 is provided at one end of the terminal posts 31.

[0027] Specifically, buffer pads 5 are provided on both sides of the casing 11. The buffer pads 5 are used to cushion the casing 11. The inner side of the buffer pads 5 is bonded to the surface of the casing 11 with strong structural adhesive, and the outer side is processed with irregularly distributed protrusions at intervals. The height of the protrusions is 2-3 mm and the diameter is 5-8 mm. When the battery is subjected to a lateral impact, the hemispherical protrusions first contact the obstacle and undergo elastic deformation, dissipating the impact energy through the viscoelasticity of the material.

[0028] Specifically, the compressive strength layer 13 has a honeycomb structure. Each cell of the honeycomb structure is a regular hexagon with a side length of 3-5 mm and a wall thickness of 0.5-1 mm. The honeycomb structure of the compressive strength layer 13 is made of 6061 aluminum alloy through stamping and welding processes. The regular hexagonal cells are arranged regularly, resulting in isotropic mechanical properties. When the battery is subjected to axial pressure, the thin-walled cells of the honeycomb structure undergo plastic buckling deformation, absorbing energy through the folding and stretching of the cell walls. According to finite element analysis, this structure can generate a compression stroke of 20-30 mm under a pressure of 100 MPa, with an energy absorption efficiency of 80-90 J / cm². 3 .

[0029] Specifically, the injection assembly 4 includes an injection port and a sealing plug, and the sealing plug and the injection port are connected by threads.

[0030] Specifically, a groove is provided on one side of the sealing adhesive 32, the groove being at least used to prevent battery fluid from creeping into the alkali.

[0031] Operating steps: 1. Insert the battery into the terminal 31 of the battery cover 21;

[0032] 2. Align the slide groove 12 with the groove on the battery cover 21 and use the sealing color glue 32 to seal and assemble.

[0033] 3. Connect the designated device via pole 31. When liquid needs to be added, simply unscrew the liquid injection assembly 4.

[0034] Fourth, when subjected to compression, the thin wall of the compression-resistant layer 13 can undergo elastic deformation to absorb energy. Its side length of 3-5mm and wall thickness of 0.5-1mm ensure that while providing sufficient buffer space, it also has reasonable structural strength, significantly improving the battery's compression resistance and reducing the risk of battery damage caused by external compression.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
