In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

As shown in fig. 1, according to an embodiment of the present application, there is provided an electrical equipment mounting box including: a housing and a seal 20.

Wherein, the box includes main body 10 and lid 30, is provided with installation space 12 and opening on the main body 10, and the opening communicates with installation space 12, and lid 30 detachably covers and establishes on main body 10 in order to cover the opening. The sealing member 20 is provided between the body 10 and the cover 30, and seals a gap at a junction of the body 10 and the cover 30, and a buffer portion 50 is provided in the sealing member 20.

Specifically, the installation space 12 in the main body 10 is available for installation of devices, and the cover 30 is detachably connected to the main body 10, so that maintenance of the electrical equipment installation box is facilitated. Since the case is provided separately and the body 10 is provided with the installation space 12 and the opening, it is necessary to use the sealing member 20 to improve the protection performance of the entire electric equipment installation case. In the prior art, when the sealing member 20 is assembled between the body 10 and the cover 30, the body 10 and the cover 30 exert an external force on the sealing member 20, so that the sealing member 20 is in a state of high pressure exhaustion. In the present embodiment, the buffer portion 50 is disposed in the sealing member 20, and the buffer portion 50 can weaken the external force applied to the sealing member 20 by the main body 10 and the cover 30, so that the problem that the sealing performance of the sealing member 20 is invalid due to long-term high-pressure fatigue state of the sealing member 20 is solved to a certain extent.

Further, the buffer 50 includes at least one channel disposed within the seal 20. When the seal 20 is subjected to an external pressure, the external force is transmitted to the passage by the force transmission, and the passage is in a hollow state, so that the passage does not generate a reaction force to the seal 20, thereby relieving the internal stress of the seal 20 to some extent. In one embodiment of the present application, the buffer portion 50 includes two passages, which are disposed side by side in the height direction of the sealing member 20 in the sealing member 20. Alternatively, the buffer 50 may also include a plurality of passages, and the plurality of passages are uniformly provided in the seal 20. Optionally, a buffer may also be filled in the channel of the buffer portion 50 to enable the buffer portion 50 to attenuate the stress of the seal 20.

Further, an annular groove 11 is provided on a side of the body 10 close to the cover 30 and/or a side of the cover 30 close to the body 10, the annular groove 11 is provided around the periphery of the opening, and the seal 20 is installed in the annular groove 11. It should be noted that "the side of the main body 10 close to the cover 30 and/or the side of the cover 30 close to the main body 10 is provided with the annular groove 11" means one of three cases that the side of the main body 10 close to the cover 30 is provided with the annular groove 11, the side of the cover 30 close to the main body 10 is provided with the annular groove 11, and the side of the main body 10 close to the cover 30 and the side of the cover 30 close to the main body 10 is provided with the annular groove 11. In this embodiment, the annular groove 11 is used for positioning the sealing member 20, and the annular groove 11 is arranged around the periphery of the opening, so that the sealing member 20 can seal the gap between the main body 10 and the cover body 30, and the overall protection performance of the electrical equipment mounting box is enhanced. In one embodiment, as shown in fig. 1 and 2, the electrical equipment mounting case is a rectangular case, and the annular groove 11 is provided on a side of the main body 10 near the cover 30 and corresponds to the rectangular case shape.

In addition, the seal 20 is in interference fit with the annular groove 11, so that abrasion between the seal 20 and the annular groove 11 can be reduced on the one hand. On the other hand, the installation can be completed without the cooperation of other components, and the production cost of the electric equipment installation box is reduced to a certain extent.

Further, the body 10 is provided with an annular groove 11, and the seal 20 includes: rectangular section 21 and semicircular section 22. Wherein the rectangular section 21 is mounted in an annular recess 11 in the body 10. The semicircular section 22 is connected with the rectangular section 21, a part of the semicircular section 22 is installed in the annular groove 11 on the main body 10, and the top end of the semicircular section 22 is propped against the cover body 30.

Specifically, as shown in fig. 4 to 6, the seal 20 is divided into a rectangular section 21 and a semicircular section 22 in the height direction of the seal 20. The rectangular section 21 is a rectangle-like shape having a chamfer at a rectangular right angle in the cross section of the lower portion of the seal 20, and the chamfer is provided to reduce the wear of the rectangular section 21 and the annular groove 11 to some extent. Likewise, the semicircular segment 22 means that, in the cross section of the seal 20, the cross section of the upper portion of the seal 20 is semicircular. When the seal 20 is assembled, the rectangular section 21 is fitted into the annular groove 11 on the main body 10 such that the rectangular section 21 is in sufficient contact with the bottom of the annular groove 11. Meanwhile, the top end of the semicircular section 22 is propped against the cover body 30, compared with the traditional mode that the rectangular section 21 and the cover body 30 are propped against, the semicircular section 22 has similar sealing effect with the rectangular section 21, and the semicircular section 22 can be better adapted to the cover body 30 and the box body with different shapes. At the same time, the semicircular segments 22 are more material efficient than the conventional rectangular segments 21. Next, in this embodiment, a part of the semicircular section 22 is installed in the annular groove 11, so that after the upper end of the semicircular section 22 is abutted, the semicircular section 22 installed in the annular groove 11 is fully contacted with the side wall of the annular groove 11, and the overall structural stability is improved.

Further, as shown in fig. 5, the buffer portion 50 includes: a first buffer channel 23 and a second buffer channel 24. Wherein the first buffer channel 23 is arranged in the semicircular section 22. The second buffer channel 24 is provided within the rectangular section 21, and the inner diameter of the second buffer channel 24 is larger than the inner diameter of the first buffer channel 23. Specifically, the external force applied to the semicircular segment 22 by the cover 30 can be reduced by the first buffer channel 23, and the rectangular segment 21 can reduce the external force applied to the rectangular segment 21 by the outside through the second buffer channel 24. Since the rectangular section 21 receives not only the external force applied by the annular groove 11 but also the external force transmitted by the main body 10 and the cover 30 through the semicircular section 22, the rectangular section 21 receives an external force greater than the semicircular section 22, so that the external force applied by the rectangular section 21 can be better weakened by increasing the volume of the second buffer passage 24.

Further, in this embodiment, the thickness H of the seal 20 is 2mm or more. Since the buffer 50 is provided in the sealing member 20, when the thickness H of the sealing member 20 is in a small range, such as the thickness H of the sealing member 20 is 2mm to 4mm, the performance of the electrical equipment mounting case can be still brought to the IP67 level. And when the thickness H of the sealing member 20 is less than 2mm, the sealing member 20 is too thin and is easily damaged by an external force. In general, the thickness of the seal 20 of this embodiment may be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.

Alternatively, in this embodiment, the wall thickness M of the tank is 3mm or more. In particular, in the electrical equipment installation box in the prior art, when the wall thickness of the box body is smaller than 5mm, it is difficult to ensure that the protection performance of the electrical equipment installation box can reach the IP67 level. In the present embodiment, however, since the sealing member 20 with the buffer portion 50 is provided, when the wall thickness of the case is 3mm or more, for example, the wall thickness of the case may be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or the like, the case can still secure the protection performance thereof to the IP67 level. Further, the electrical equipment mounting box of the present embodiment can reduce the production cost of the electrical equipment mounting box by reducing the thickness H of the seal 20 and reducing the wall thickness M of the box body while ensuring the protection thereof.

Further, the seal 20 includes one of a silicone rubber seal, a polytetrafluoroethylene seal, and a polyester seal. Specifically, the seal 20 in this embodiment is a silicone rubber seal, and the characteristics of excellent fatigue resistance, wear resistance and the like of the silicone rubber seal are benefited, so that the protective performance life of the electrical equipment installation box can be improved to a certain extent. Meanwhile, the silicon rubber sealing piece has good telescopic performance, and the sealing piece 20 is convenient to be in interference fit with the annular groove 11. Alternatively, the seal 20 may be a polytetrafluoroethylene seal or a polyester seal having good wear resistance and mechanical properties.

As shown in fig. 1 and 3, the seal member 20 is further provided with a relief portion 25, and the relief portion 25 is used to relieve the connection member 40 between the main body 10 and the cover 30. The cover 30 is connected with the main body 10 through the connecting piece 40, so as to prevent the connecting piece 40 from affecting the sealing piece 20, the embodiment is provided with the avoiding portion 25 on the sealing piece 20 for avoiding the connecting piece 40, so as to prevent the connecting piece 40 from damaging the sealing piece 20.

It should be noted that the seal 20 of the present embodiment has different sizes and sizes for adapting to different sizes and sizes of electrical equipment mounting boxes. In the manufacturing process of the sealing member 20 of this embodiment, firstly, injection molding and extrusion molding are performed in a grinding tool, then the sealing member 20 is cut according to the electrical equipment installation boxes with different sizes, and finally, two ends of the sealing member 20 are bonded, so that the sealing member 20 with the required size can be obtained.

The installation process of the electrical equipment installation box in the present embodiment is: first the rectangular section 21 of the seal 20 is embedded along the annular groove 11 at the bottom of the annular groove 11. After the rectangular section 21 of the sealing member 20 is completely embedded into the bottom of the annular groove 11, i.e., after the rectangular section 21 of the sealing member 20 abuts against the main body 10, the cover 30 is mounted on the main body 10 by means of screws. At this time, the semicircular section 22 of the sealing member 20 abuts against the cover 30, so that the sealing member 20 has a sealing effect on the case. The electrical equipment installation box of this embodiment is installed conveniently, waterproof and dustproof performance is excellent, and long service life.

On the other hand, the application also provides an energy storage device, which comprises the electric device mounting box in the embodiment, and therefore, the energy storage device comprises all the technical effects of the electric device mounting box in the embodiment. Since the technical effects of the electrical equipment installation case have been described in detail in the foregoing, a detailed description thereof will be omitted.
