[0024] like Figures 1 to 3 As shown, the embodiment of the present application provides an energy storage battery that is easy to disassemble and assemble, including a bracket assembly 1, a battery pack 2 arranged in the bracket assembly 1, and a power supply port 3 arranged on the bracket assembly 1 and electrically connected to the battery pack 2, the bracket assembly 1 includes a positive pole bracket 11 and a negative pole bracket 12 detachably connected to the positive pole bracket 11, the surfaces of the positive pole bracket 11 and the negative pole bracket 12 are both attached with insulating plates 4, and the two insulating plates 4 are respectively provided with positive contact points 41 and negative contact points 42 corresponding to the two ends of each battery on one side facing the battery pack 2; wherein the positive contact points 41 are mutually conductive, and the negative pole insulations are mutually conductive.

[0025] In the embodiment of the present application, the above-mentioned bracket assembly 1 is composed of a positive bracket 11 and a negative bracket 12 spliced ​​together and detachable, and an internal cavity is formed between the positive bracket 11 and the negative bracket 12, and the battery pack 2 is arranged in the internal cavity, wherein the battery pack 2 includes a plurality of batteries, and the arrangement order of the two levels of the batteries is consistent, and an insulating plate 4 is attached to the side of the positive bracket 11 and the negative bracket 12 away from the battery, and the insulating plate 4 can be fixedly attached to the bracket assembly 1 or detachably attached, and the two insulating plates 4 are fixedly provided with a positive contact point 41 and a negative contact point 42 that are abutted against the two ends (two levels) of each battery on one side of the bracket assembly 1, wherein it should be noted that the above-mentioned positive contact point 41 and the negative contact The distribution positions of the points 42 correspond to the two ends of the battery, so that the positive contact point 41 and the negative contact point 42 can contact the battery to form an electrical connection. In addition, the positive contact points 41 are mutually conductive through the aluminum strips, and the negative contact points 42 are mutually conductive through the aluminum strips, so that the batteries can be connected in series. Since the positive bracket 11 and the negative bracket 12 are detachably connected, when a battery in the battery pack 2 needs to be replaced, only the positive bracket 11 and the negative bracket 12 need to be disassembled, and the positive contact point 41 and the negative contact point 42 are respectively arranged on the two insulating plates 4, so the battery can be replaced directly by disassembling the positive bracket 11 and the negative bracket 12, which facilitates the disassembly and assembly of the energy storage battery when replacing the battery.

[0026] Further, such as Figure 1 As shown, the bracket assembly 1 is also provided with a clamping member 5 for detachably connecting the positive electrode bracket 11 and the negative electrode bracket 12 .

[0027] In the embodiment of the present application, the above-mentioned clamping component 5 is arranged on the end face of the bracket assembly 1. Specifically, at the position where the two opposite end faces of the bracket are spliced, by arranging the clamping component 5, when the battery needs to be replaced, only the clamping component 5 needs to be disassembled so that the bracket assembly 1 can be disassembled, and by arranging the clamping component 5, the positive electrode bracket 11 and the negative electrode bracket 12 can be fixed to each other to prevent poor contact due to looseness between the positive electrode bracket 11 and the negative electrode bracket 12.

[0028] Further, such as Figure 3 As shown, the clamping member 5 includes a male plug 51 arranged on the end surface of the positive electrode support 11, and a female seat 52 arranged on the end surface of the negative electrode support 12, and the female seat 52 and the male plug 51 are detachably clamped to each other.

By splicing the positive pole support 11 and the negative pole support 12 together, the male plug 51 can be inserted into the female socket 52, so that the positive pole support 11 and the negative pole support 12 are spliced ​​together, and because the positive contact point 41 and the negative contact point 42 are arranged on the insulating plate 4, and the insulating plate 4 is fixedly fitted with the positive pole support 11 and the negative pole support 12, the positive contact point 41 and the negative contact point 42 can be tightly abutted against the two ends of the battery, thereby preventing poor contact.

[0030] Optional, such as Figure 2 and Figure 3 As shown, the surfaces of the positive electrode support 11 and the negative electrode support 12 are both provided with through holes 13 corresponding to the positions of the two ends of each battery, and each of the positive electrode contact points 41 and each of the negative electrode contact points 42 passes through each through hole 13 to abut against the two ends of each battery.

A plurality of through holes 13 are also provided on the surface of the negative electrode bracket 12, and the position of the through hole 13 also corresponds to the axial position of the negative terminal of the battery. By providing the through holes 13, the positive electrode contact point 41 and the negative electrode contact point 42 can pass through the through holes 13 to contact the positive and negative electrodes of the battery, so that the batteries can be connected in series, and the power supply port 3 can output the required voltage.

[0032] Optional, such as Figure 2 and Figure 3 As shown, a mounting position 14 is recessed on the side where the positive electrode support 11 and the negative electrode support 12 are in contact with the insulating plate 4 , and the insulating plate 4 can be detachably mounted in the mounting position 14 .

By installing the insulating plate 4 in the mounting position 14, the insulating plate 4 can be fixed during assembly to prevent the insulating plate 4 from being offset from the bracket assembly 1, thereby causing poor contact with the battery.

[0034] Optional, such as Figure 1 As shown, grooves 111 are provided at the four corners of the positive electrode support 11 near the insulating plate 4 , and bumps 112 matched with the grooves 111 are provided at the four corners of the negative electrode support 12 near the insulating plate 4 .
