[0044] Example 1

[0045] Firstly, such as Figures 1 to 4 As shown, an embodiment of the present invention provides a housing assembly for a power battery, comprising:

[0046] Heat-insulating protective box 1, used to house the battery;

[0047] The heat insulation limiting unit 3, installed inside the heat insulation protective box 1, is used to limit and fix batteries of different sizes and provide heat insulation; the heat insulation limiting unit 3 includes a heat insulation partition for dividing the space and a limiting structure; and

[0048] The sealing and fixing unit 4 is installed on the heat insulation and protection box 1 to achieve the sealing and detachable fixing of the heat insulation and protection box 1.

[0049] Specifically, in the embodiments of the present invention, such as Figures 1 to 4 As shown, the heat insulation box 1 is a hollow rectangular shell structure. The heat insulation limiting unit 3 is located in the rectangular inner cavity of the heat insulation box 1. The heat insulation limiting unit 3 also includes a bottom heat insulation plate 31, which is fixedly connected to the lower inner side of the heat insulation box 1. The bottom heat insulation plate 31 has limiting holes 32 for limiting the limiting structure. Multiple limiting holes 32 are provided, and all limiting holes 32 are densely distributed on the bottom heat insulation plate 31. The battery is placed on the bottom heat insulation plate 31. The bottom heat insulation plate 31 insulates the heat below, and the limiting holes 32 limit the heat insulation partition and the limiting structure, thereby dividing the internal space of the heat insulation box 1. The heat insulation limiting unit 3 can divide the rectangular inner cavity of the heat insulation box 1 into multiple accommodating cavities of different sizes. The accommodating cavities are used to place batteries, thereby accommodating and fixing batteries of different sizes.

[0050] In embodiments of the present invention, such as Figures 1 to 4As shown, the heat insulation partition includes an insulating heat insulation plate 34, and a limiting structure includes a limiting post 33. The lower end of the limiting post 33 is slidably connected to a limiting hole 32. The insulating heat insulation plate 34 is connected to the limiting post 33, and the insulating heat insulation plate 34 and the limiting post 33 are vertically arranged. The insulating heat insulation plate 34 is located above the bottom heat insulation plate 31. The lower end of the limiting post 33 is inserted into the limiting hole 32, and the limiting hole 32 limits the limiting post 33, thereby limiting the insulating heat insulation plate 34. A first fixing bolt 35 is provided on the limiting post 33, and the first fixing bolt 35 is threadedly connected to the limiting post 33 and the limiting hole 32 respectively. The limiting post 33 is limited by the limiting hole 32, the insulating heat insulation plate 34 provides heat insulation and space division between the batteries, and the limiting post 33 is fixed by the first fixing bolt 35 to limit and insulate the battery, forming a double fixation of limiting and locking. It can withstand greater vibration load, avoid hard collisions caused by battery movement, and improve fixation stability.

[0051] In embodiments of the present invention, such as Figures 1 to 4 As shown, multiple insulating heat insulation plates 34 and limiting posts 33 are provided. Each insulating heat insulation plate 34 is connected to two oppositely arranged limiting posts 33, and each insulating heat insulation plate 34 is located between the two oppositely arranged limiting posts 33. The two ends of the insulating heat insulation plate 34 are snap-fitted to the two limiting posts 33, and each accommodating cavity is formed by surrounding multiple insulating heat insulation plates 34. The insulating heat insulation plates 34 are available in various models with different lengths and sizes, and the limiting posts 33 can be selectively inserted into one of the limiting holes 32. The spacing between the two limiting posts 33 and the corresponding size of the insulating heat insulation plate 34 can be adjusted according to the battery size to achieve zoned limiting of batteries of different sizes. This adjustable space division design breaks through the size limitations of traditional fixed structures and significantly improves the compatibility of the casing with diverse batteries.

[0052] In embodiments of the present invention, such as Figures 1 to 4 As shown, an air gel layer 36 is provided on the inner side of the heat insulation and protection box 1. The air gel layer 36 is attached to the insulating heat insulation plate 34 and the limiting post 33. The air gel layer 36 is located between the inner wall surface of the heat insulation and protection box 1 and the insulating heat insulation plate 34. The air gel layer 36 provides heat insulation for the battery and the outer protection device, maximizing the isolation of heat conduction and improving safety.

[0053] In embodiments of the present invention, such as Figures 1 to 4As shown, the sealing and fixing unit 4 includes a top cover 41 and a sealing ring 44. The lower end of the top cover 41 has a limiting groove 42 that mates with the upper end of the heat insulation box 1. The sealing ring 44 is embedded in the limiting groove 42 and is sandwiched between the top cover 41 and the heat insulation box 1. A heat-insulating sponge 43 for buffering and limiting is fixedly connected to the upper inner side of the top cover 41. The sealing ring 44 provides a sealing function when fixed to the heat insulation box 1, the limiting groove 42 provides both sealing and limiting functions, and the heat-insulating sponge 43 further ensures that the parts do not move arbitrarily when the device is moved, thus ensuring the stability of the battery position. The heat-insulating sponge 43 not only provides heat insulation but also absorbs vibration energy during vehicle operation through elastic deformation, reducing rigid collisions between the battery and the casing.

[0054] In embodiments of the present invention, such as Figures 1 to 4 As shown, the sealing and fixing unit 4 also includes a limiting seat 45 and a movable block 46. The two limiting seats 45 are fixedly connected to the left and right ends of the top cover 41, and the movable block 46 is rotatably connected between the two limiting seats 45. A second fixing bolt 47 is threadedly connected to the middle of the outer side of the movable block 46. Two threaded holes 48 that mate with the second fixing bolt 47 are opened in the middle of the left and right ends of the heat insulation box 1. The second fixing bolt 47 is threadedly connected to the threaded holes 48. The limiting seats 45 limit the movable block 46, and the second fixing bolt 47 is threadedly connected to the movable block 46 and the threaded holes 48, so that the top cover 41 is fixed on the heat insulation box 1, achieving the purpose of fixing the heat insulation box 1 and the top cover 41.

[0055] like Figures 1 to 4 As shown, the power battery housing assembly of this embodiment of the invention also includes a mounting plate 2, which has an L-shaped structure. The front and rear ends of the heat insulation and protection box 1 are fixedly connected to the mounting plate 2 by a third fixing bolt 7. The lower end of the mounting plate 2 has three threaded fixing holes 6 for external installation. The mounting plate 2 is fixed by the third fixing bolt 7, and the heat insulation housing assembly is easily fixed by the threaded fixing holes 6.

[0056] The working principle of the power battery housing assembly with the above structure is as follows:

[0057] The bottom heat insulation plate 31 isolates the heat below, and the limiting hole 32 limits the limiting structure, thereby dividing the space and forming multiple accommodating cavities to accommodate and fix batteries of different sizes. The limiting hole 32 limits the limiting post 33, and the insulating heat insulation plate 34 provides heat insulation and space division between the batteries. The first fixing bolt 35 fixes the limiting post 33, thereby limiting and insulating the battery. The air gel layer 36 insulates the battery and the outer protective device, maximizing the insulation against heat conduction. The sealing ring 44 provides a sealing function when fixed to the heat insulation and protection box 1, and the limiting groove 42 provides sealing and limiting functions. The heat insulation sponge 43 further ensures that the parts do not move arbitrarily when the device is moved, ensuring the stability of the battery position. The movable block 46 is limited by the limiting seat 45, and the second fixing bolt 47 is threadedly connected to the movable block 46 and the threaded hole 48, so that the top cover 41 is fixed on the heat insulation box 1, thereby achieving the purpose of fixing the heat insulation box 1 and the top cover 41. The mounting plate 2 is fixed by the third fixing bolt 7, and the heat insulation shell is easily fixed by the threaded fixing hole 6.
