[0021] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings used in the embodiments of the present application. The described embodiments are only some of the embodiments of the present application, but not all of the embodiments. The components in the embodiments of the present application shown in the drawings here can be arranged and designed in various arrangement ways.

[0022] Therefore, the following description of the embodiments of the present application shown in the drawings only illustrates selected embodiments of the present application, and does not limit the scope of the present application to be protected. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without using inventive ability also belong to the protection scope of the present application.

[0023] Like reference numerals refer to like elements in the drawings, so that a definition in one drawing does not require further definition or interpretation in the other drawings.

[0024] In the description of this application, the directions or positional relationships expressed by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the drawings or are normal arrangement directions or positional relationships of the products related to the invention, and are merely for the purpose of simply and concisely explaining this application, and do not necessarily express or imply that the relevant devices or elements have a specific direction, or are constructed or operated in a specific direction, and therefore do not limit this application. In addition, terms such as "first", "second", and "third" are merely for the purpose of distinction and explanation, and do not express or imply relative importance.

[0025] Additionally, terms such as "horizontal" and "vertical" do not mean that a component is placed absolutely horizontally or vertically, but may be slightly tilted. For example, "horizontal" means that the orientation of the component is merely more horizontal than "vertical," and does not require that the component be completely horizontal, but may be slightly tilted.

For example, they may be fixedly connected, detachably connected, or integrally connected. They may be mechanically connected or electrically connected. They may also be directly connected, indirectly connected via an intermediate object, or the insides of two elements may communicate with each other. Those skilled in the art can understand the specific meanings of the above terms in this application according to the specific circumstances.

[0027] As disclosed in the Background section, in the prior art, stacked batteries usually adopt a recessed pull tab and connect upper and lower batteries by directly tightening a screw in the recessed area, which causes the internal space of the battery to be compressed and makes it inconvenient to install the screw through the recessed structure.

[0028] In the prior art, there is a proposal to stack batteries one above the other, and then add a fixing sheet and corresponding tightening screws to the side to connect the upper and lower batteries, but this proposal requires the installation of a separate fixing sheet and is not very effective because it uses side fixing. There is also a proposal to form a male-female connection structure on the side after stacking the batteries one above the other, and then fix the batteries by tightening screws on the side, but this proposal also uses side fixing, so the fixing effect is not good, the structure is complicated, and installation is inconvenient.

[0029] In order to solve the above problems, the present application provides a new type of stacked battery pack that can achieve a thin stacked structure, has a small installation area after stacking, has a simple appearance, is easy to install, does not compress the internal space of the battery, and contributes to maximum utilization of the space.

[0030] First Example

[0031] 1 to 3, this embodiment provides a stacked battery pack 100. The stacked battery pack 100 can achieve a thin stacked structure, has a good fixing effect, requires a small installation area after stacking, has a simple appearance, is simple in structure, is easy to install during stacking, and does not compress the internal space of the battery, contributing to maximum utilization of the space.

[0032] The stacked battery pack 100 according to this embodiment includes a battery pack body 110, a fixing handle 130, and a fixing holder 150. The battery pack bodies 110 are installed in a stacked manner, the fixing holder 150 is installed on the bottom edge of the battery pack body 110, and the fixing handle 130 is installed on the top edge of the battery pack body 110, and is installed corresponding to the adjacent fixing holder 150 and removably connected thereto, thereby stacking and fixing two adjacent battery pack bodies 110.

[0033] In this embodiment, the battery pack body 110 has a rectangular block shape and several cells are installed inside. When stacking, a plurality of battery pack bodies 110 are stacked and installed, and the battery cabinet 10 is formed by covering the outside with a housing. Adjacent battery pack bodies 110 are connected to each other by a fixing handle 130 at the top of one battery pack body 110 and a fixing holder 150 at the bottom of the other battery pack body 110, thereby realizing the fixing of the two adjacent battery pack bodies 110.

[0034] The battery pack body 110 according to this embodiment employs a vertically stacked structure, and both the top and bottom surfaces of the battery pack body 110 are flat, which contributes to direct stacking, and after stacking, the fixed holder 150 and the fixed handle 130 are connected to realize positional restriction. The fixed handle 130 also serves as a grip, facilitating transportation of the battery pack body and allowing the stacking operation to proceed smoothly.

[0035] In this embodiment, the fixing handle 130 is installed on both edge portions of the top of the battery pack body 110 and protrudes to both sides of the top of the battery pack body 110, and the fixing holder 150 is installed on both edge portions of the bottom of the battery pack body 110 and protrudes to both sides of the bottom of the battery pack body 110. A first connection hole is provided in the fixing handle 130, a second connection hole is provided in the fixing holder 150, and a connection member 133 is removably attached to the second connection hole, and the connection member 133 is configured to connect the fixing holder 150 and the fixing handle 130 adjacent to each other. Specifically, each battery pack body 110 has fixed handles 130 installed on both sides of the top and fixed holders 150 installed on both sides of the bottom. When the battery pack body 110 is transported, it is transported using the fixed handles 130, and once stacked, the position is restricted by the fixed handles 130, so that the fixed handles 130 have the functions of gripping and restricting the position.

[0036] In this embodiment, the fixed handle 130 has a structure in which a through hole is formed in the middle, and a gripping opening 131 is formed on the inside. Specifically, the fixed handle 130 protrudes outward from both sides of the battery pack body 110, and a through hole is provided in the middle to form the gripping opening 131. When actually transporting the battery pack body 110, the fixed handle 130 is gripped by passing the hand through the gripping opening 131, which makes it easier to transport the battery pack body 110.

[0037] In this embodiment, a wiring structure 170 is further installed on the side of the battery pack body 110, and electrical wiring is connected to the wiring structure 170. The electrical wiring is installed to penetrate the gripping opening 131 so as to be accommodated inside the fixing handle 130. Specifically, the electrical wiring may be a power line and a communication line, and the electrical wiring is connected after stacking, and the electrical wiring is accommodated inside the gripping opening 131, so that positional restriction for the electrical wiring is realized and the wiring disorder can be avoided. Here, the fixing handle 130 has a function of passing the wire, so that the entire stacking structure is more simple.

[0038] In this embodiment, the fixed handle 130 has an arc shape and protrudes in a direction away from the battery pack body 110. Specifically, at least the grip portion of the fixed handle 130 has an arc structure, which contributes to improving the gripping feeling, and the opening range of the grip opening 131 can be made larger, which contributes to wire threading. Of course, in other preferred embodiments of the present application, the fixed handle 130 may have a rectangular, trapezoidal or other polygonal shape, and is not specifically limited here.

[0039] In order to further improve the gripping feeling, in this embodiment, the upper and lower edges of the fixed handle 130 are filleted to prevent the hand from being cut. Of course, a rubber anti-slip layer can be additionally installed, in which case the gripping friction force is increased and the gripping feeling is improved.

[0040] In this embodiment, a side cover 180 is further installed on a side of the battery pack body 110, the side cover 180 is installed to cover the wiring structure 170, and is detachably connected to an edge of the battery pack body 110, both ends of the side cover 180 extend to the fixed handle 130 and the fixed holder 150, respectively, and the electrical wiring is accommodated inside the side cover 180. Specifically, the side cover 180 according to this embodiment has a tile-like shape, is formed to match the shape of the fixed handle 130, and is flush with the fixed handle 130 in the vertical direction, ensuring a neat appearance and realizing shielding and protection of internal lines.

[0041] In this embodiment, a fixed block 135 is installed inside the fixed handle 130, and a first connection hole is provided in the fixed block 135. Specifically, the fixed block 135 is integrally provided inside the fixed handle 130, and the first connection hole is provided at the center, which allows the connection member 133 to be easily attached.

[0042] In this embodiment, the first connection hole is a threaded hole, the connection member 133 is a fixing screw, and the fixing screw penetrates the second connection hole and is screwed into the threaded hole to fix the fixed block 135 and the fixed holder 150 relatively. Specifically, the fixing screw is installed from top to bottom, penetrates the second connection hole first, and is then screwed into the first connection hole to achieve fixation. Of course, in other preferred embodiments of the present application, both the first connection hole and the second connection hole may be a general through-hole structure, the connection member 133 may be a bolt, and the fixed block 135 and the fixed holder 150 may be fixed relatively by screwing the bolt and the nut together.

[0043] As described above, this embodiment provides a stacked battery pack 100. The stacked battery pack 100 has a fixing holder 150 installed at the bottom edge of the battery pack body 110, a fixing handle 130 installed at the top edge of the battery pack body 110, and the fixing handle 130 protrudes outward and is installed corresponding to the adjacent fixing holder 150 and detachably connected thereto, thereby stacking and fixing two adjacent battery pack bodies 110. This embodiment uses a handle structure protruding outward, which prevents the internal space of the battery pack body 110 from being compressed, contributing to maximum utilization of the space of the battery pack. Furthermore, the detachable connection between the fixing handle 130 and the fixing holder 150 in the adjacent battery pack bodies 110 realizes mutual position restriction and fixing of the adjacent battery pack bodies 110, which realizes a thin stacked structure, which has a small installation area after stacking, a simple appearance, and an easy installation operation due to the handle structure protruding outward.

The basic structure, principle, and technical effects of the stacked battery pack 100 are the same as those of the first embodiment, so for convenience of explanation, the corresponding contents of the first embodiment can be referred to for parts not mentioned in this embodiment.

[0046] In this embodiment, a plurality of battery pack bodies 110 are stacked in order, and the fixing handles 130 and the fixing holder 150 of two adjacent battery pack bodies 110 are correspondingly installed and detachably connected to each other, so that the two adjacent battery pack bodies 110 are relatively fixed. The battery cabinet 10 further includes a cabinet body and a control module. The control module may be installed independently or may be installed in a pile in the battery pack bodies 110, and the bottom battery pack body 110 is attached to the ground or a base by the fixing holder 150.

[0047] In this embodiment, the battery cabinet 10 further includes a handle cover plate 190. The handle cover plate 190 is configured to cover the top of the uppermost battery pack body 110 and cover the uppermost fixed handle 130.

[0048] When actually assembling, first, the first battery pack body 110 is fixed directly to the ground or to a base, the second battery pack body 110 is stacked on top of the first battery pack body 110, and the fixing screws on both sides are tightened, and all the battery pack bodies 110 are stacked and fixed in this manner. Then, wiring is performed for the power lines and communication lines on both sides of the battery pack, and the wiring is passed through the fixing handle 130. After all operations are completed, the side covers 180 on both the left and right sides are attached, and the handle cover plate 190 on the top is attached to complete the assembly of the system.
