Description

Technical Field

[0001] This utility model relates to the field of power battery technology, specifically to a power battery pack that can be assembled quickly. Background Technology

[0002] A power battery pack, or simply a battery pack, is an integral structure assembled from one or more battery modules via connectors, a cooling system, and other components. It is used to provide power for electric vehicles and other new energy vehicles. The power battery pack is the core component in new energy vehicles used to store electrical energy and output power. It typically consists of multiple battery modules, a thermal management system, a battery management system (BMS), an electrical system, and structural components.

[0003] Utility model patent CN202323404078.3 discloses a battery pack body, a battery pack, and a power supply system. The battery pack body, battery pack, and power supply system include a housing; a heat exchanger disposed on the housing, with a gap between the heat exchanger and the housing; and a filler disposed within the gap, with a first surface of the filler connected to the heat exchanger and a second surface connected to the housing. The thickness of the filler is 5mm to 10mm. By providing a filler within the gap between the heat exchanger and the housing, the filler can connect the heat exchanger and the housing into a single unit, thereby enhancing the structural strength, impact resistance, and structural stability of the battery pack body. Simultaneously, the filler thickness of 5mm to 10mm can reduce the cost of the battery pack body while maintaining its structural strength and impact resistance, and improve its lightweight performance and the volumetric energy density of the battery pack.

[0004] Although the battery pack, battery assembly, and power system offer advantages in cost reduction, the device still presents the following problems in practical use: In the design of the power battery pack, the upper and lower shells are connected and fixed using multiple bolts. While this design ensures the structural stability of the battery pack, it introduces inconvenience during assembly and disassembly. Assembly requires installing multiple bolts one by one, which is cumbersome; similarly, disassembly requires removing these bolts one by one, a time-consuming and labor-intensive process that significantly reduces the efficiency of assembling and disassembling the power battery pack. Therefore, we propose a power battery pack that allows for quick assembly. Utility Model Content

[0005] To address the aforementioned challenges, this invention provides a power battery pack that can be assembled quickly.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A power battery pack that can be assembled quickly includes a housing with a top opening. Multiple partitions are fixed to the top opening of the housing, and two sealing strips are fixed to the top of the outer wall of the housing.

[0008] The top of the shell is provided with a cover plate, which is open at the bottom and front end. A flange is fixed at the edge of the cover plate, and the inner wall of the flange fits against the top of the outer wall of the shell. Two sealing grooves are opened on the inner wall of the flange, and the sealing strip is inserted into the corresponding sealing groove. Multiple limiting holes are opened at the front edge of the cover plate.

[0009] A fixing component is installed at the front end of the housing. The fixing component includes a fixing seat that is fixedly connected to the housing. The top of the fixing seat has multiple sliding cavities, and a slider is slidably installed in each of the sliding cavities. A limit rod is fixed at the top of the slider and the limit rod is inserted into a corresponding limit hole. A connecting rod is fixed at the bottom of each slider. The connecting rod passes through the fixing seat and is slidably connected to the fixing seat. A spring is sleeved on the outside of the connecting rod to press against the slider.

[0010] Furthermore, a limiting block is coaxially fixed to the bottom end of the connecting rod, and the diameter of the limiting block is larger than the diameter of the connecting rod.

[0011] Furthermore, the front end face of the fixed base is provided with multiple connecting grooves that communicate with the sliding cavity, and a lever is slidably installed in each connecting groove, with the end of the lever being fixedly connected to the slider.

[0012] Furthermore, a groove is provided on the top of the housing, and a sealing ridge is embedded in the groove.

[0013] Furthermore, the cover plate and the flange are integrally bent and formed, and both the cover plate and the flange are made of aluminum alloy.

[0014] Furthermore, the limiting rod, slider, and connecting rod are located on the same vertical axis, and the limiting rod, slider, and connecting rod are integrally formed structures.

[0015] Furthermore, the partition is fixedly connected to the inner wall of the shell by bolts, and the shell is made of aluminum alloy.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The design incorporates a housing, cover plate, and fixing components. The cover plate and housing are slidably connected via an insertion between a sealing strip and a sealing groove. A limiting rod, engaged with a limiting hole, limits the cover plate, resulting in a more stable connection between them. To remove the cover plate, the limiting rod disengages from the limiting hole, and the cover plate is then pushed away from the housing. This design, through its quick-release mechanism between the cover plate and housing, improves the convenience and efficiency of battery pack assembly and disassembly. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment provides a technical solution:

[0030] Please see Figures 1-6As shown, a quick-assembly power battery pack includes a housing 1 with a top opening. Multiple partitions 10 are fixed to the top opening of the housing 1, and two sealing strips 11 are fixed to the top of the outer wall of the housing 1. A cover plate 2 is provided on the top of the housing 1, with openings at both the bottom and front end. A flange 20 is fixed to the edge of the cover plate 2, and the inner wall of the flange 20 fits against the top of the outer wall of the housing 1. Two sealing grooves 21 are formed on the inner wall of the flange 20, and the sealing strips 11 are inserted into the corresponding sealing grooves 21. A sealing groove is formed at the front edge of the cover plate 2. There are multiple limiting holes 22; a fixing component 3 is installed at the front end of the housing 1. The fixing component 3 includes a fixing seat 30 fixedly connected to the housing 1. Multiple sliding cavities 300 are opened on the top of the fixing seat 30. A slider 31 is slidably installed in each of the sliding cavities 300. A limiting rod 32 is fixed at the top of the slider 31. The limiting rod 32 is inserted into the corresponding limiting hole 22. A connecting rod 33 is fixed at the bottom of each slider 31. The connecting rod 33 passes through the fixing seat 30 and is slidably connected to the fixing seat 30. A spring 35 for pressing against the slider 31 is sleeved on the outside of the connecting rod 33.

[0031] In this embodiment, a limiting block 34 is coaxially fixed to the bottom end of the connecting rod 33, and the diameter of the limiting block 34 is larger than the diameter of the connecting rod 33. The limiting block 34 prevents the connecting rod 33 from detaching from the fixed seat 30, thereby ensuring the stable use of the slider 31.

[0032] In this embodiment, the front end face of the fixed base 30 is provided with multiple connecting grooves 301 that communicate with the sliding cavity 300. A lever 36 is slidably installed in each connecting groove 301, and the end of the lever 36 is fixedly connected to the slider 31. The position of the slider 31 can be easily adjusted by the lever 36, thereby facilitating the adjustment of the position of the limiting rod 32.

[0033] In this embodiment, a groove 12 is provided on the top of the housing 1, and a sealing ridge 13 is embedded in the groove 12. The sealing ridge 13 is made of rubber, which has good sealing performance. Therefore, the sealing ridge 13 can increase the tightness of the connection between the cover plate 2 and the housing 1.

[0034] In this embodiment, the cover plate 2 and the flange 20 are integrally bent and formed, and both the cover plate 2 and the flange 20 are made of aluminum alloy. The integral bending and forming process ensures the connection strength between the cover plate 2 and the flange 20, thereby ensuring the service life of the cover plate 2 and the flange 20; at the same time, aluminum alloy has good corrosion resistance and lightweight advantages.

[0035] In this embodiment, the limiting rod 32, the slider 31, and the connecting rod 33 are located on the same vertical axis, and the limiting rod 32, the slider 31, and the connecting rod 33 are integrally formed. This design enhances the rigidity and stability among the limiting rod 32, the slider 31, and the connecting rod 33, and improves the durability and reliability of the limiting rod 32, the slider 31, and the connecting rod 33.

[0036] In this embodiment, the partition 10 is fixedly connected to the inner wall of the housing 1 by bolts, and the housing 1 is made of aluminum alloy. The bolt fixing method ensures a tight fit and stable connection between the partition 10 and the housing 1, and the housing 1 is made of aluminum alloy, which has the advantages of being lightweight and strong.

[0037] It should be added that, in this embodiment, the fixing base 30 is fixedly connected to the front end of the housing 1 by bolts. This connection method ensures a tight fit and stable connection between the fixing base 30 and the housing 1, improving the rigidity and stability of the overall structure. At the same time, this connection method also has the advantage of being easy to assemble and disassemble.

[0038] In practical use, the user first aligns the front end of the sealing groove 21 with the sealing strip 11 and inserts it. The sealing groove 21 then slides along the sealing strip 11. At the same time, the user presses the lever 36 upwards. The lever 36 drives the slider 31 to slide along the slide cavity 300. The spring 35 is compressed by the slider 31. The slider 31 then drives the limiting rod 32 to retract into the slide cavity 300. When the rear end of the flange 20 presses against the rear end of the housing 1, the user releases the lever 36. Under the elastic action of the spring 35, the slider 31 moves upwards and drives the limiting rod 32 to move upwards. The limiting rod 32 then inserts into the limiting hole 22, and the cover plate 2 is fixedly connected to the housing 1.
