[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0029] See also Figure 1 and Figure 2 The utility model provides an embodiment of an energy storage cabinet, including a cabinet body 1, a first bracket 21, a second bracket 22 and an energy storage unit 4; the cabinet body 1 is provided with an opening 11; along the second direction Y, the first bracket 21 and the second bracket 22 are relatively arranged inside the cabinet body 1, the first bracket 21 and the second bracket 22 are enclosed to form a receiving space 23, and the receiving space 23 is connected to the opening 11; the energy storage unit 4 is located between the first bracket 21 and the second bracket 22, and the energy storage unit 4 is configured to enter the receiving space 23 along the first direction X through the opening 11.

[0030] In some embodiments, the energy storage cabinet includes a filling piece 3, and the filling piece 3 at least partially contains the receiving space 23. The filling piece 3 is connected to the side of the first bracket 21 close to the energy storage unit 4. The filling piece 3 abuts against one side of the energy storage unit 4, provides a limiting effect and a pre-tightening effect on one side of the energy storage unit 4, so that one side of the energy storage unit 4 squeezes the first bracket 21 to fix the energy storage unit 4 in the receiving space 23 enclosed between the first bracket 21 and the second bracket 22, reducing the probability of the energy storage unit 4 loosening or moving, thereby improving the stability of the energy storage unit 4, thereby improving the safety of the energy storage cabinet, wherein the first direction X and the second direction Y are perpendicular.

[0031] See also Figure 3 and Figure 4 , and please also refer to Figure 8 The filling member 3 is provided with a first inclined portion 31 inclined relative to the first bracket 21, and the first inclined portion 31 and the first direction X form a first angle A, and the first angle A is an obtuse angle. The first inclined portion 31 is configured to guide the energy storage unit 4 into the receiving space 23. Through the above-mentioned structural arrangement, it is possible to guide the energy storage unit 4, so that the energy storage unit 4 enters the receiving space 23 according to the first direction X, thereby improving the accuracy of the process of the energy storage unit 4 entering the receiving space 23, and thus improving the installation efficiency of the energy storage unit 4. In addition, through the above-mentioned structural arrangement, it is also possible to reduce the probability of collision and friction between the energy storage unit 4 and the first bracket 21, reduce the risk of damage to the energy storage unit 4 due to incorrect entry into the receiving space 23, and extend the service life of the energy storage unit 4.

[0032] See also Figure 3 and Figure 4 The filling member 3 includes a first fixing portion 32 , a contact portion 33 and a second fixing portion 34 ; the first fixing portion 32 is fixed to the first bracket 21 , and the second fixing portion 34 is fixed to the first bracket 21 ; the contact portion 33 contacts the energy storage unit 4 .

[0033] In some embodiments, the first inclined portion 31 connects the first fixed portion 32 and the abutting portion 33. Along the second direction Y, the first fixed portion 32 and the abutting portion 33 are spaced apart by the first inclined portion 31. When the abutting portion 33 receives a force from the energy storage unit 4, the force can be transmitted to the first inclined portion 31. The first inclined portion 31 can be deformed, which is conducive to the abutting portion 33 abutting against the energy storage unit 4.

[0034] In some embodiments, see Figure 5 The surface of the abutment portion 33 facing the receiving space 23 is perpendicular to the second direction Y. When the filling piece 3 abuts against one side of the energy storage unit 4 along the second direction Y, the surface of the abutment portion 33 facing the receiving space 23 contacts and fits with the surface of one side of the energy storage unit 4, which can increase the contact area between the filling piece 3 and the energy storage unit 4, thereby enhancing the connection stability between the filling piece 3 and the energy storage unit 4, thereby reducing the probability of the energy storage unit 4 loosening or moving, thereby improving the stability of the energy storage unit 4 and improving the safety of the energy storage cabinet.

[0035] See also Figure 3 and Figure 4, the filling piece 3 is provided with a second inclined portion 32 inclined relative to the first bracket 21, and the second inclined portion 32 and the first direction X have a second angle B, and the second angle B is an obtuse angle. Along the second direction Y, the projection of the abutting portion 33 is located between the projection of the first fixing portion 32 and the projection of the second fixing portion 34. Through the above-mentioned structural arrangement, the filling piece 3 is trapezoidal, which can improve the structural stability of the filling piece 3. In the process of the filling piece 3 abutting and supporting one side of the energy storage unit 4, the pressure is balanced, and the phenomenon of excessive pressure on one side of the filling piece 3 is reduced, thereby reducing the probability of damage or deformation of the filling piece 3 due to uneven force. In addition, through the above-mentioned structural arrangement, the filling piece 3 is trapezoidal, which can also facilitate the deformation of the filling piece 3, which is conducive to the abutment of the abutment portion 33 against the energy storage unit 4.

[0036] It should be understood that the first fixing portion 32 and the second fixing portion 34 are fixed to the first bracket 21 including but not limited to one or more of threaded connection, clamping connection, snap connection or magnetic connection.

Through the above-mentioned structural setting, the length of the filling piece 3 along the first direction X can be indirectly increased, and then the abutting area of ​​the filling piece 3 and the same side of the energy storage unit 4 can be indirectly increased, thereby enhancing the abutting stability of the filling piece 3 and the energy storage unit 4.

Through the above height setting, one side of the energy storage unit 4 and the first fastener 5 can be spaced apart along the second direction Y, reducing the probability of the energy storage unit 4 contacting the first fastener 5 along the second direction Y, thereby reducing the probability of the first fastener 5 scratching the energy storage unit 4 during the process of the energy storage unit 4 entering the receiving space 23 along the first direction X. Optionally, H1mm-H2mm>5mm.

[0042] See also Figure 6 and Figure 8 In some embodiments, the first crossbar 212 includes a first portion 212a and a second portion 212b connected to each other, the first portion 212a carries the energy storage unit 4, and the second portion 212b and the energy storage unit 4 are spaced apart along the second direction Y to form a gap 6. The first portion 212a extends along the first direction X, and the second portion 212b extends along the third direction Z.

[0043] In some embodiments, along the second direction, the filling member 3 is located in the gap 6 , and a portion of the first fastener 5 is located in the gap 6 .

Both of the two filling pieces 3 at least partially extend into the receiving space 23, and the two filling pieces 3 are arranged opposite to each other along the second direction Y, and the two filling pieces 3 abut against the opposite sides of the energy storage unit 4 respectively. Through the above-mentioned structural arrangement, it is possible to reduce excessive pressure on one side of the energy storage unit 4, thereby making the pressure on both sides of the energy storage unit 4 uniform, thereby achieving the purpose of dispersing the pressure.

Through the above-mentioned structural arrangement, a spacing space can be formed between the energy storage unit 4 and the second fastener 7 along the second direction Y, thereby reducing the energy storage unit 4 from contacting the second fastener 7 along the second direction Y, thereby reducing the probability of the second fastener 7 scratching the energy storage unit 4 during the process of the energy storage unit 4 entering the receiving space 23 along the first direction X.
