Referring to fig. 1-5, the present utility model provides a wall-mounted energy storage device 100, which includes a housing 110 having a receiving cavity 110a, a hanging member 120 fixed on the housing 110 and configured to be hung at a designated position, and a battery assembly 130 received in the receiving cavity 110 a; the battery assembly 130 includes two oppositely disposed holders 131, a plurality of batteries 132 interposed between the two holders 131, and a binder 133 sleeved on the outer circumferences of the two holders 131, the binder 133 being used to bind the two holders 131 to bind the holders 131 and the batteries 132 together.

In the embodiment of the present utility model, the binder 133 is sleeved on the outer circumferences of the two clamps 131, and the two clamps 131 are restrained by the binder 133, so that the two clamps 131 are difficult to separate from each other after a certain distance. The plurality of batteries 132 are then placed between the clamping members 131 such that the batteries 132 are filled in the space between the two clamping members 131. At this time, the force applied to the clamping member 131 by the battery 132 and the force applied to the clamping member 131 by the binder 133 are balanced, so that the battery assembly 130 is integrally formed, and finally the battery assembly 130 is received in the receiving chamber 110a through the housing 110 to protect the battery assembly 130.

According to the technical scheme, the combination structure of the clamping piece 131 and the binder 133 is adopted, so that the integration of a plurality of batteries 132 is realized, the overall structure is relatively simple, the assembly is convenient and fast, the manufacturing cost is low, and the problems of complex structure and process and high manufacturing cost of the wall-mounted energy storage device 100 in the prior art are solved.

It is to be understood that this embodiment is not limited to the order in which the clip 131, binder 133, and battery 132 are assembled.

In addition, there may be a variety of materials for binder 133. When binder 133 is a rigid material, a certain limit is required on the number of batteries 132 and the width of grip 131. When binder 133 is a flexible material, such as a rope, it may be bound after clamp 131 and battery 132 are assembled.

In this embodiment, the binder 133 is a rigid material that is easier for personnel to assemble than a flexible material after appropriate dimensional parameters are set.

Specifically, the hanging member 120 is provided with a plurality of waist-shaped holes so as to be hung to a designated position by screws.

Referring to fig. 2-5, in one embodiment of the present utility model, a limiting groove 131a adapted to the binder 133 is formed at an end of the clamping member 131 away from the battery 132, and the binder 133 is embedded in the limiting groove 131 a.

In this embodiment, after the battery assembly 130 is installed, the limiting groove 131a can restrict the binder 133 to prevent the binder 133 from separating from the clamping member 131, so that the structural stability of the battery assembly 130 can be improved.

In a specific embodiment, as shown in fig. 5, the limiting groove 131a extends along the length direction VL of the clamping member 131 and penetrates the clamping member 131. Referring to fig. 1 and 2 in combination, the housing 110 includes a first shell 112 and a second shell 114, and the first shell 112 and the second shell 114 are buckled to form the accommodating cavity. When battery assembly 130 is placed within the receiving cavity, binder 133 encloses a plane parallel to the bottom surface of the receiving cavity. Thus, the upper and lower end surfaces of battery assembly 130 are restrained by first housing 112 and second housing 114, and the side surfaces are restrained by binder 133, so that battery 132 is less likely to separate from binder 133 after vibration.

Preferably, the batteries 132 are arranged in a widthwise direction, and both ends of the batteries 132 in a lengthwise direction are abutted against the binder 133.

It is understood that references to binder 133 being held against battery 132 in this embodiment refer to a macroscopic holding, and that it is within the scope of this embodiment that there are errors in the process that result in failure of battery 132 to contact binder 133. So designed, relative movement between battery 132 and binder 133 is avoided as much as possible.

In yet another embodiment, as shown in fig. 4, the battery assembly 130 further includes a plurality of separators 134, the separators 134 being interposed between two adjacent batteries 132.

It is noted that the separator 134 not only prevents the short circuit caused by the contact between the batteries 132, but also compensates for errors during assembly. For example, the thickness of the separator 134 is 0.5mm, and if a gap of 2mm exists between the battery 132 and the holder 131 after the battery 132 is placed, the gap can be filled by adding four separators 134.

With continued reference to fig. 4, in yet another embodiment, the battery assembly 130 further includes a support 135, and the plurality of batteries 132 are disposed on the support 135. In this embodiment, the support 135 mainly serves to protect the battery 132.

In addition, the battery assembly 130 includes a cover plate 136 that covers the plurality of batteries 132. The cover plate 136 is mainly used for electrically connecting the plurality of batteries 132 and protecting the batteries 132.

Referring to fig. 2, 3 and 5, in another embodiment of the present utility model, two positioning members 140 are disposed in the accommodating cavity, the battery assembly 130 is disposed between the two positioning members 140, and the positioning members 140 are abutted against the clamping members 131. In this embodiment, the positioning member 140 mainly positions the battery assembly 130 to prevent the battery assembly 130 from moving in the direction.

Preferably, the number of the battery packs 130 is two or more, and is disposed in a row along the extending direction of the positioning member 140.

In a specific embodiment, a positioning groove 131b is formed at the bottom of the clamping member 131, the positioning groove 131b extends to the external space in a direction away from the battery 132, and the positioning member 140 is received in the positioning groove 131b and abuts against the inner wall of the positioning groove 131 b.

Spatially, the positioning member 140 and the clamping member 131 are stacked. In this way, the internal space of the housing 110 can be saved, so that the wall-mounted energy storage device 100 is more compact.

In a more specific embodiment, the positioning member 140 is provided with a first connecting hole 140a, the clamping member 131 is provided with a second connecting hole 131c and a connecting member, the second connecting hole 131c is communicated with the first connecting hole 140a, and the connecting member is inserted into the first connecting hole 140a through the second connecting hole 131c to connect the positioning member 140 and the clamping member 131.

It should be noted that, in the present embodiment, on the basis of making the wall-mounted energy storage device 100 compact, the battery assembly 130 can be fixed on the positioning member 140 through the design of the first connecting hole 140a and the second connecting hole 131 c.

Further, the first connection hole 140a is a threaded hole, the second connection hole 131c is a through hole, preferably a waist hole, and the connection member is a screw.

Referring to fig. 1, in another embodiment of the present utility model, a handle 150 for being lifted by a user and a leg 160 for supporting the housing 110 are further provided on the housing 110, and the handle 150 and the leg 160 are respectively located on the upper and lower sides of the housing 110.

The design of the handles 150 and the legs 160 of the present embodiment can facilitate the placement and transportation of the wall-mounted energy storage device 100 in a non-hanging state.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
