Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features can be combined with each other.

[0036] In existing technology, the battery box includes a box frame and a protective plate, with the protective plate located on the outside of the box frame to form a sealed space. When the battery box is cracked or damaged due to external impact, it is necessary to manually disassemble the battery box, locate the damaged area, and then perform operations such as welding or sealing glue filling.

[0037] However, manually repairing the battery casing is rather inconvenient.

[0038] To overcome the shortcomings of existing technologies, the battery box and battery pack provided in this application embodiment include a box frame, a protective plate assembly, and a repair assembly. The protective plate assembly is disposed on the outside of the box frame, and the repair assembly is disposed between the protective plate assembly and the box frame. When the repair assembly is subjected to external force, it can trigger and repair cracks on the protective plate assembly caused by external impact, effectively ensuring that the airtightness of the battery box is not affected. Compared with the prior art, which requires manual disassembly of the battery box and operation such as positioning and sealing repair, the battery box provided in this application embodiment can achieve automatic repair without manual operation, making the repair of the battery box more convenient and faster.

[0039] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0040] Reference Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a battery housing, including:

[0041] Box frame 100, box frame 100 is used to house the battery module;

[0042] The protective panel assembly 200 is disposed on the outside of the housing frame 100;

[0043] Repair component 300 is disposed between the protective plate assembly 200 and the housing frame 100. Repair component 300 is configured to be triggered when the external force is greater than or equal to a preset value to repair the crack in the protective plate assembly 200.

[0044] It is understood that the housing frame 100 provides a relatively independent and stable space for the battery modules, ensuring their normal operation and lifespan. The housing frame 100 has multiple accommodating spaces for the battery modules, allowing them to be arranged and placed in an orderly manner within the housing frame 100. The housing frame 100 has multiple mounting holes for easy installation of the battery housing onto other equipment. For example, the housing frame 100 can be a die-cast aluminum alloy frame, ensuring dimensional accuracy and structural strength, resulting in a high-strength and lightweight housing frame 100.

[0045] The protective plate assembly 200 is disposed on the outside of the housing frame 100, thereby forming physical protection on the outside of the housing frame 100, further protecting the housing frame 100 and the internal battery modules, reducing direct impact and scratches from external objects on the housing, and lowering the risk of damage to the battery housing. It should be noted that the protective plate assembly 200 needs to be sealed to the housing frame 100 to effectively prevent water and dust from entering the housing, avoiding problems such as short circuits that could affect battery performance and lifespan, and also preventing dust accumulation on the battery modules, reducing poor heat dissipation and electrical faults caused by dust.

[0046] The repair component 300 is disposed between the protective plate assembly 200 and the housing frame 100. When the protective plate assembly 200 is damaged and cracks appear under the action of external force, the repair component 300 is triggered under the action of external force to repair the cracks in the protective plate assembly 200, prevent the cracks from expanding further, thereby extending the service life of the protective plate assembly 200 and reducing the frequency and cost of replacing the protective plate.

[0047] Therefore, the battery housing provided in this application embodiment includes a housing frame 100, a protective plate assembly 200, and a repair assembly 300. The protective plate assembly 200 is disposed on the outside of the housing frame 100, and the repair assembly 300 is disposed between the protective plate assembly 200 and the housing frame 100. When the repair assembly 300 is subjected to external force, it can trigger and repair cracks on the protective plate assembly 200 caused by external impact, effectively ensuring that the airtightness of the battery housing is not affected. Compared with the prior art, which requires manual disassembly of the battery housing and operation such as positioning and sealing repair, the battery housing provided in this application embodiment can achieve automatic repair without manual operation, making the repair of the battery housing more convenient and faster.

[0048] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3 As shown, the repair component 300 includes:

[0049] The outer shell layer 310 is connected to the protective panel assembly 200 on the side facing the housing frame 100;

[0050] A filler layer 320 is disposed within the outer shell layer 310;

[0051] The outer shell layer 310 is configured to break when the external force is greater than or equal to a preset value, so that the filling layer 320 is released and repairs the crack.

[0052] The outer shell layer 310 is connected to the side of the protective panel assembly 200 facing the housing frame 100. Specifically, it can be snapped or glued to the flat surface of the protective panel assembly 200 facing the housing frame 100. Alternatively, a receiving groove can be provided on the protective panel assembly 200, and the protective panel assembly 200 can be placed in the receiving groove and snapped or glued. In this way, the repair component 300 can be securely placed inside the protective panel assembly 200, ensuring that the repair component 300 will not move or fall off under normal circumstances, so that the repair component 300 and the protective panel assembly 200 form a relatively integral structure.

[0053] The filler layer 320 is disposed within the outer shell layer 310, providing physical protection for the filler layer 320 and preventing it from being prematurely triggered or degraded due to external environmental factors (such as dust, moisture, mechanical friction, etc.) during normal use. When the protective plate assembly 200 breaks under external impact, air enters the inside of the protective plate assembly 200 through the gap. The outer shell layer 310 is also impacted, causing the filler layer 320 to break. Under gravity, the filler layer 320 automatically flows out of the outer shell layer 310 and into the crack through capillary action, where it interacts with the air to repair the damage. This timely treatment of the damage to the protective plate assembly 200 reduces manual intervention and maintenance costs.

[0054] By repairing cracks in a timely manner, the integrity and protective performance of the protective plate assembly 200 can be maintained, avoiding a decrease in the protective function of the battery box due to cracks, thereby improving the safety of the battery system and reducing safety hazards.

[0055] In specific implementation, refer to Figure 1 , Figure 2 and Figure 3 As shown, multiple outer shell layers 310 and multiple filling layers 320 are provided. The multiple outer shell layers 310 are distributed in a grid pattern on the protective plate assembly 200, and the multiple filling layers 320 are provided one-to-one within the multiple outer shell layers 310.

[0056] The multiple outer shell layers 310 arranged in a grid pattern allow the repair component 300 to be divided into multiple repair units. This enables the outer shell layers 310 to fully cover the protective plate component 200 and to precisely repair impact cracks at a specific location, improving the response speed and comprehensiveness of the repair. If a crack appears in a certain area of ​​the protective plate component 200, only the outer shell layer 310 at the corresponding location needs to be broken to release the filler layer 320 for repair, while the other outer shell layers 310 remain intact. This avoids excessive release of the filler layer 320, which would result in material waste, reducing repair costs, maintenance time, and workload.

[0057] For example, in this embodiment, each outer shell layer 310 is a rectangular shell with a rectangular grid distribution. In other embodiments, the outer shell layer 310 may also be a circular shell with a rectangular grid distribution, or a hexagonal shell, triangular shell, etc. with a honeycomb grid distribution. The spacing between adjacent outer shell layers 310 is consistent, and this application does not limit this.

[0058] The filler layer 320 includes a mixture of polymeric compounds and a diluent, the diluent being used to adjust the viscosity of the polymeric mixture;

[0059] The polymer compound is configured to undergo an oxidative polymerization reaction with the outside air to form a sealant layer that seals the crack.

[0060] The polymer compound undergoes an oxidative polymerization reaction with the surrounding air, causing the active groups in the polymer compound to react under the influence of oxygen in the gas, forming a sealing layer. This sealing layer, formed by the oxidative polymerization reaction, exhibits good stability and durability, maintaining a sealing effect for a considerable period and ensuring a tight seal against cracks. After the sealing layer forms, it can restore the structural strength of the protective panel assembly 200 to a certain extent, enhancing its resistance to external forces and allowing it to continue providing protection after repair. The diluent, by adjusting the viscosity of the polymer mixture, enables it to have high fluidity, allowing it to quickly spread across the protective panel assembly 200 after the outer shell layer 310 cracks.

[0061] The oxidative polymerization reaction requires no additional complex operations or external energy input. As long as the outer shell layer 310 is cracked and the filling layer 320 is exposed to the air, it can automatically start to react and gradually solidify, thereby achieving automatic repair of the crack and improving the timeliness and convenience of repair.

[0062] For example, the polymer compound can be liquid polybutadiene, liquid polyisoprene, oxidatively crosslinked chloroprene rubber, or epoxy ester resin, and the diluent includes butyl acetate or xylene. This significantly reduces the viscosity of the sealant system, allowing it to effectively penetrate into tiny gaps; at room temperature, it forms an elastic sealant layer through oxygen absorption and oxidative crosslinking, exhibiting excellent oil resistance, adhesion, and vibration resistance. After curing, the sealant layer is dense and pressure-resistant, making it particularly suitable for long-term sealing of gaps.

[0063] In addition, in some embodiments, the outer shell layer 310 is a rigid plastic shell.

[0064] The outer shell 310 is an injection-molded rigid plastic shell that provides reliable physical protection for the filler layer 320 under normal conditions, preventing it from being affected by external environmental factors during normal use. When subjected to external impact, the rigid plastic outer shell 310 easily breaks, allowing the filler layer 320 to flow out and repair the crack. Furthermore, rigid plastic is relatively inexpensive and easy to process and mold, and can be made into different shapes and specifications as needed, achieving a grid-like distribution to fully cover the protective plate assembly 200, improving the response speed to cracks and the comprehensiveness of repair, while reducing repair costs and workload.

[0065] For example, the thickness of the outer shell layer 310 is positively correlated with the magnitude of the external force required for rupture. This application does not limit the specific magnitude of the external force, but can set the thickness of the outer shell layer 310 according to the specific working conditions, and thus set the preset value of the external force.

[0066] In some embodiments, refer to Figure 1 As shown, the protective plate assembly 200 includes a base plate 210, which is connected to the bottom of the housing frame 100, and the repair assembly 300 is disposed on the base plate 210.

[0067] When the protective plate assembly 200 only includes the base plate 210 connected to the bottom of the housing frame 100, and the repair assembly 300 is installed on the base plate 210, it can focus on protecting and repairing the bottom of the battery housing. During vehicle operation, the bottom of the battery housing is susceptible to impact from road stones, water erosion, etc. The repair assembly 300 can promptly repair cracks in the base plate 210, preventing moisture, dust, etc. from entering the housing and affecting the performance and lifespan of the battery modules.

[0068] Or, refer to Figure 2 As shown, the protective plate assembly 200 includes a bottom plate 210 and multiple side plates 220. The multiple side plates 220 are connected to the periphery of the box frame 100. Multiple repair components 300 are provided, and the multiple repair components 300 are respectively provided on the bottom plate 210 and the side plates 220.

[0069] When the protective plate assembly 200 includes a base plate 210 and multiple side plates 220 connected to the periphery of the housing frame 100, and multiple repair components 300 are respectively installed on the base plate 210 and the side plates 220, the protection range is more comprehensive. The periphery of the battery housing may also be subjected to external impacts such as side collisions and scratches. The repair components 300 on the side plates 220 can repair cracks in the side plates 220 in a timely manner, ensuring the airtightness of the battery housing in all aspects, avoiding the decline in the protective function of the battery housing due to cracks, and improving the safety of the battery system.

[0070] In specific implementation, the base plate 210 and the side plate 220 can be bolted to the box frame 100 for easy disassembly and assembly, so as to facilitate the replacement of the used repair component 300. In some embodiments, the base plate 210 and the side plate 220 can also be welded to the box frame 100.

[0071] Furthermore, in some embodiments, reference is made to Figure 1 and Figure 2 As shown, the battery housing also includes a seal 500, and the protective plate assembly 200 and the housing frame 100 are sealed together by the seal 500.

[0072] The protective plate assembly 200 is sealed to the housing frame 100 by the sealing element 500, forming a more stable and sealed integrated structure between the protective plate assembly 200 and the housing frame 100, preventing liquid or gas leakage within the housing frame 100. Stable airtightness can maintain the relative stability of the internal environment of the battery housing, reduce the interference of external environmental factors on the battery module, and improve the reliability and safety of the battery system.

[0073] For example, the seal 500 may be a sealant applied to the connection between the guard plate assembly 200 and the housing frame 100, or a sealing strip embedded in the connection between the guard plate assembly 200 and the housing frame 100.

[0074] Furthermore, in some embodiments, reference is made to Figure 1 and Figure 2 As shown, the battery housing also includes a liquid cooling plate 400, which is disposed between the housing frame 100 and the protective plate assembly 200 and connected to the housing frame 100.

[0075] The liquid cooling plate 400 can make the temperature distribution inside the battery box more uniform, avoiding damage to the battery caused by excessive local temperature. A uniform temperature environment helps extend the battery's lifespan and reduce performance degradation caused by temperature differences. The liquid cooling plate 400 has internal coolant channels, where the coolant circulates and carries away the heat generated inside the battery box.

[0076] In actual production, for battery boxes of different sizes and specifications, the dimensions of the box frame 100, the size and shape of the liquid cooling plate 400, the number and distribution of the outer shell layer 310 in the repair component 300, and the thickness of the protective plate component 200 can be adjusted according to actual needs.

[0077] For example, for large battery boxes, the strength and thickness of the box frame 100 can be appropriately increased, a larger liquid cooling plate 400 can be selected to improve heat dissipation efficiency, and the number of repair components 300 can be increased to ensure effective automatic repair in a larger bottom area.

[0078] Taking a car battery pack as an example, during vehicle manufacturing, the battery pack is installed in the battery mounting position under the electric vehicle chassis. When the bottom of the battery pack is bumped by road obstacles during vehicle operation, the repair component 300 on the base plate 210 can quickly function to automatically repair the damaged area, ensuring the normal operation of the battery and preventing vehicle malfunctions or safety accidents caused by battery pack damage. In energy storage power stations, the battery pack can be mounted on a specific bracket. When it is bumped by external objects or due to ground vibrations, the repair component 300 on the base plate 210 or side plate 220 can also automatically repair itself, ensuring the stable operation of the energy storage power station.

[0079] This application also provides a battery pack, including a battery module and a battery housing, wherein the battery module is disposed in the battery housing.

[0080] The battery housing has been described in the above embodiments and will not be repeated here.

Compared with the prior art, which requires manual disassembly of the battery box and operation such as positioning and sealing repair, the battery box provided in this application embodiment can achieve automatic repair without manual operation, making the repair of the battery box more convenient and faster.
