After continuous research, design, and repeated sample making and improvement, a practical and valuable utility model has finally been created.

[0050] Please refer to Figures 1 to 6 , the embodiment of the present utility model provides a wall-mounted energy storage battery, which makes the explosion-proof effect and safety of the wall-mounted energy storage battery better.

[0051] The wall-mounted energy storage battery includes a wall-mounted bracket 1, a main housing 2, and a sealing cover plate 3.

[0052] The wall-mounted bracket 1 is in a U-shape, including a base plate portion 11 for hanging on the wall and two fixed plate portions 12 arranged in parallel at intervals, and the base plate portion 11 and the fixed plate portions 12 are fixedly connected; preferably, the two fixed plate portions 12 are respectively connected to both ends of the base plate portion 11, and the distance between the two fixed plate portions 12 is equal to the width of the main housing 2.

[0053] An opening for installing the battery module 6 is provided on the back of the main housing 2, the opening faces the base plate portion 11, and the two fixed plate portions 12 are respectively connected to two opposite side wall plates 21 of the main housing 2, thereby keeping the main housing 2 fixed in the air, that is, the side wall plates 21 play the role of fixing the main housing 2. When the sealing cover plate 3 is blown open and ejected, the wall-mounted bracket 1 is connected to the main housing 2 through the fixed plate portions 12, and can better withstand the recoil force of the high-temperature gas, avoiding the main housing 2 flying out and hurting people.

[0054] The sealing cover plate 3 is installed on the main housing 2 to close the opening, and the two opposite sides of the sealing cover plate 3 respectively abut against the back of the main housing 2 and the base plate portion 11. It should be particularly noted that, in this embodiment, the sealing cover plate 3 is not only fixedly connected to the main housing 2, but also the base plate portion 11 of the wall-mounted bracket 1 presses against the sealing cover plate 3, improving the fixing effect on the sealing cover plate 3, thereby effectively improving the explosion-proof effect of the wall-mounted battery and effectively reducing the possibility of the sealing cover plate 3 flying out and hurting people.

[0055] It should also be particularly noted that the wall-mounted bracket 1 is used to hang on the wall, which will make the sealing cover plate 3 face the wall, that is, when the sealing cover plate 3 flies out, it will probably hit the wall, which will effectively reduce the possibility of the sealing cover plate 3 flying out and hurting people.

[0056] Optionally, the thickness of the sealing cover plate 3 is less than that of the main housing 2. That is, when the battery module 6 explodes and catches fire, the sealing cover plate 3 will be broken through first instead of the main housing 2, reducing the possibility of high-temperature and high-pressure gas directly rushing towards the user. Generally, it is the top or bottom of the sealing cover plate 3 that deforms and is pushed open, thereby relieving the high-temperature gas inside the main housing 2.

[0057] Optionally, the height of the substrate part 11 is less than that of the sealing cover plate 3; in the height direction, the top of the sealing cover plate 3 protrudes from the top of the substrate part 11, and the bottom of the sealing cover plate 3 protrudes from the bottom of the substrate part 11; the part of the sealing cover plate 3 that protrudes from the substrate part 11 in the height direction is called the exposed part, and there is a gap between the exposed part and the wall. The gap between the exposed part and the wall provides space for the sealing cover plate 3 to be bent by impact. When the sealing cover plate 3 is impacted by high-temperature gas, the two ends of the top and bottom are relatively more likely to be broken through, and the sealing cover plate 3 is easily bent into a C-shaped structure and hooked on the substrate part 11, further reducing the possibility of the sealing cover plate 3 flying out, which also further improves the safety performance of the wall-mounted energy storage battery.

[0058] Optionally, a hanging hook 13 is provided on the back of the substrate part 11 away from the main housing 2; a guiding part 14 is provided at the tail of the hanging hook 13, and the guiding part 14 is inclined relative to the substrate part 11, so that an inverted V-shaped opening is formed between the guiding part 14 and the substrate part 11. The inverted V-shaped opening can make the hanging hook 13 easier to hang at a suitable position, reducing the hanging difficulty of the wall-mounted energy storage battery and making the hanging operation easier to achieve.

[0059] Optionally, the wall-mounted energy storage battery further includes a wall-mounted fixing bracket 4 installed on the wall; a protruding part 41 is provided on the wall-mounted fixing bracket 4, and a hanging groove 42 corresponding to the hanging hook 13 is provided on the protruding part 41, and the hanging groove 42 penetrates through the protruding part 41; the hanging hook 13 can pass through the hanging groove 42 and hang on the protruding part 41. The protruding part 41 has a certain thickness for the hanging hook 13 to hang. In addition, it should be noted that the wall-mounted fixing bracket 4 includes a support plate and an expansion bolt connecting the support plate, and the expansion bolt penetrates into the wall, thereby fixing the support plate on the wall. It should also be noted that the support plate includes a protruding part 41 and a support part that abuts against the wall, and the protruding part 41 protrudes outward relative to the support part, thereby forming a space for accommodating the hanging hook 13, so that the hanging hook 13 can hang on the protruding part 41. It should be further supplemented that a plurality of hanging hooks 13 are provided on the wall-mounted bracket 1, and a plurality of hanging grooves 42 corresponding to the plurality of hanging hooks 13 are provided on the wall-mounted fixing bracket 4. In this embodiment, four hanging hooks 13 are provided on the wall-mounted bracket 1.

[0060] Optionally, a plurality of waist-shaped holes 1201 are formed in the fixed plate portion 12, and the center lines of all the waist-shaped holes 1201 are parallel to the horizontal direction; the plurality of waist-shaped holes 1201 are arranged in an S shape. Specifically, the arrangement of the waist-shaped holes 1201 can better take into account the thickness error of the substrate portion 11 and the machining error of the main housing 2, enabling the substrate portion 11 to better fit and abut against the back of the sealing cover plate 3, thus forming a good explosion-proof effect. It should be further elaborated that when the fixed plate portion 12 is torn by an external force, if the distance between two adjacent waist-shaped holes 1201 is too close, the fixed plate portion 12 is likely to be torn and cause the two adjacent waist-shaped holes 1201 to communicate, reducing the fixing strength. The arrangement of the plurality of waist-shaped holes 1201 in an S shape can increase the distance between two adjacent waist-shaped holes 1201 and reduce the possibility of communication between two adjacent waist-shaped holes 1201.

[0061] Optionally, an annular sealing ring 31 is provided on the side surface of the sealing cover plate 3 away from the wall-mounted bracket 1; an annular elastic portion 201 corresponding to the annular sealing ring 31 is provided on the main housing 2, and the annular sealing ring 31 abuts against the annular elastic portion 201. As Figure 3 shown, the cross-section of the annular elastic portion 201 is in a "C" shape, and one side of the bottom extends and is connected to the body of the main housing 2, and the suspended end at the top presses against the annular sealing ring 31, thereby forming a sealed space in the main housing 2. In this embodiment, the annular elastic portion 201 elastically presses against the annular sealing ring 31, so that the sealing effect is better.

[0062] Optionally, as Figure 4 shown, the sealing cover plate 3 is connected to the main housing 2 by a threaded fastener 5, and the substrate portion 11 is provided with an avoidance hole 1101 for avoiding the threaded fastener 5, so that the fixing effect at each position of the outer ring of the sealing cover plate 3 is more uniform, thereby further enhancing the sealing effect of the annular sealing ring 31.

[0063] Optionally, the wall-mounted energy storage battery further includes a battery module 6 installed in the main housing 2; a first groove is formed in one side side wall plate 21 of the main housing 2, and a circuit breaker assembly 7 electrically connected to the battery module 6 is installed in the first groove; a second groove is formed in the other side side wall plate 21 of the main housing 2, and a connector assembly 8 electrically connected to the battery module 6 is installed in the second groove. It should be noted that the first groove and the second groove form handle grooves on both sides, which are convenient for carrying the wall-mounted energy storage battery, that is, it can make it easier for the user to lift the wall-mounted energy storage battery.

[0064] Optionally, the wall-mounted energy storage battery further includes a main control bracket 91 installed on one side of the top of the battery module 6, a main control board 92 is installed on the main control bracket 91, and the main control board 92 is respectively connected to the battery module 6, the circuit breaker assembly 7 and the connector assembly 8; both the main control bracket 91 and the main control board 92 are installed in the main housing 2.

[0065] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as the direct or indirect implementation of the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
