[0050] In the embodiments of the present application, a housing is provided, and this housing can be used in a battery device 100 or other devices.

[0051] The housing includes a sealing cover 1 and a tray 2. The sealing cover 1 covers the tray 2, and an accommodation space is formed between the sealing cover 1 and the tray 2, where components such as a battery module, a connection row 61, and a cold plate are accommodated.

[0052] Furthermore, an installation hole 11 is formed in the sealing cover 1, and the installation hole 11 penetrates through the outer wall 12 and the inner wall 13 of the sealing cover 1; an installation bracket 21 is provided on the tray 2, and a part of the end of the installation bracket 21 facing the sealing cover 1 extends into the installation hole 11. The end face of the end of the installation bracket 21 facing the sealing cover 1 is flush with the outer wall 12 of the sealing cover 1. A threaded hole or a smooth hole is formed in the installation bracket 21. The connecting piece 3 partially passes through the installation hole 11 and is threadedly connected to the threaded hole or is in interference fit with the smooth hole. Since a part of the end of the installation bracket 21 facing the sealing cover 1 extends into the installation hole 11 and the end face of the end of the installation bracket 21 facing the sealing cover 1 is flush with the outer wall 12 of the sealing cover 1, the other part of the connecting piece 3 abuts against the end of the installation bracket 21 facing the sealing cover 1 to form a hard-to-hard contact, and the other part of the connecting piece 3 is also hermetically connected to the sealing cover 1 to seal the gap between the connecting piece 3 and the sealing cover 1, thereby avoiding the airtight problem caused by the torque decay of the soft connection.

[0053] In an optional embodiment, the housing further includes a first sealing member 4; the installation bracket 21 includes a first installation portion 211 and a second installation portion 212, and a step 213 is formed between the first installation portion 211 and the second installation portion 212.

And the end face of the first seal 4 away from the sealing cover 1 abuts against the step 213, and the end face of the first seal 4 close to the sealing cover 1 abuts against the inner wall 13 of the sealing cover 1. When the connecting member 3 is connected to the mounting bracket 21, the connecting member 3 will abut against the outer wall 12 of the sealing cover 1 and generate a pressing force on the sealing cover 1. The first seal 4 can absorb a certain pressing force to play a buffering and supporting role, avoiding damage to the sealing cover 1 when installing the connecting member 3. In addition, the first seal 4 can also play a role in sealing the gap between the mounting bracket 21 and the sealing cover 1.

[0056] In an optional embodiment, the thickness of the first seal 4 is 0.5 mm - 2.5 mm.

[0057] Among them, the thickness of the first seal 4 is within the numerical range of 0.5 mm - 2.5 mm. It can not only play a role in buffering the pressing force, but also reduce the occupied space. Preferably, the thickness of the first seal 4 is 1 mm.

The second seal 5 is embedded in the accommodation groove 33 and abuts against the outer wall 12 of the sealing cover 1.

[0059] As Figure 4 shown, an annular accommodation groove 33 is formed on the end face of the abutting portion 32 facing the outer wall 12 of the sealing cover 1. The depth direction of the accommodation groove 33 extends in a direction away from the sealing cover 1; the housing further includes a second seal 5. The second seal 5 is embedded in the accommodation groove 33, so as to be able to seal the gap between the connecting member 3 and the sealing cover 1, and also play a role in buffering the pressing force between the connecting member 3 and the sealing cover 1, so as to avoid damage to the sealing cover 1 caused by the connecting member 3.

[0060] In an optional embodiment, the connecting member 3 includes a connecting portion 31 and an abutting portion 32 arranged in a T shape. The connecting portion 31 is connected to the mounting bracket 21. The abutting portion 32 abuts against the outer wall 12 of the sealing cover 1 and the end of the mounting bracket 21.

[0061] As Figure 4 and Figure 5As shown, the connecting member 3 includes a connecting portion 31 and an abutting portion 32 that are connected in a T-shape. The connecting portion 31 is connected to the mounting bracket 21, and the abutting portion 32 is used to abut against the outer wall 12 of the sealing cover 1 and the end of the mounting bracket 21. Among them, the connecting portion 31 is columnar, with threads formed circumferentially. A threaded hole is provided in the mounting bracket 21, and the connecting portion 31 is screwed into the threaded hole, so as to form a firm connection relationship between the connecting member 3 and the mounting bracket 21, and thus a firm connection relationship is also formed between the sealing cover 1 and the tray 2. The abutting portion 32 is located outside the mounting bracket 21 and the sealing cover 1. The end surface of the abutting portion 32 close to the outer wall 12 of the sealing cover 1 abuts against the outer wall 12 of the sealing cover 1 and the end of the mounting bracket 21, and the abutting portion 32 also serves to facilitate the installation of the connecting portion 31.

[0062] In an optional embodiment, the receiving groove 33 is opened on the end surface where the abutting portion 32 abuts against the outer wall 12 of the sealing cover 1, and the second sealing member 5 is embedded in the receiving groove 33 and abuts against the outer wall 12 of the sealing cover 1.

[0063] As Figure 4 and Figure 7 shown, in an optional embodiment, the radial cross-section of the second sealing member 5 is in an H shape.

[0064] Among them, the second sealing member 5 of this shape can play a role in evenly distributing pressure, and its two sides can apply pressure evenly, so as to achieve an even sealing effect on the entire sealing surface; it can enhance its stability. When the second sealing member 5 is under the pressure between the connecting member 3 and the sealing cover 1, it is not easy to deform, which helps to maintain the long-term sealing performance.

[0065] In an optional embodiment, the first sealing member 4 has a projection surface on the outer wall 12 of the sealing cover 1, and the second sealing member 5 at least partially overlaps with the projection surface.

When installing the connecting member 3, since the second sealing member 5 is located between the connecting member 3 and the sealing cover 1, its sealing performance can be ensured when the second sealing member 5 is pressed, and the first sealing member 4 can also play a role in support and buffering.

[0067] In an optional embodiment, the first sealing member 4 is made of foam material; and / or the second sealing member 5 is made of foam material.

[0069] In another specific embodiment, the first seal 4 is made of foam material.

[0070] In another specific embodiment, the second seal 5 is made of foam material.

[0071] Among them, the foam has good sealing performance and can return to its original state even after compression, which helps to maintain long-term sealing performance; the foam material is light and will not add too much weight to the housing; the foam can absorb the pressing force to play a buffering role.

[0072] In an alternative embodiment, the tray 2 further includes a cross beam 22, and the mounting bracket 21 is arranged on the cross beam 22.

[0073] The tray 2 includes a cross beam 22. The cross beam 22 can enhance the structural strength of the tray 2.

The sealing cover 1 is connected to the cross beam 22 through the connecting member 3 and the mounting bracket 21, thereby improving the connection strength between the sealing cover 1 and the tray 2.

[0074] In an alternative embodiment, the number of the mounting brackets 21 is multiple, and the multiple mounting brackets 21 are arranged on the cross beam 22 at intervals. The multiple mounting brackets 21 can be arranged at intervals along the length direction of the cross beam 22; by providing multiple mounting brackets 21, when the sealing cover 1 is connected to the tray 2, there are multiple connection positions, further improving the connection strength between the sealing cover 1 and the tray 2.
