[0028] With the popularity of electric loaders, the design and layout requirements of power batteries used in conjunction with electric loaders are becoming more and more refined. At present, most battery brackets of electric loaders adopt a frame structure or a layered stacking structure, and each layer of battery bracket basically uses plates or profiles to form a fully enclosed space. The advantage of such a design is that the assembly process is relatively simple, and the fully enclosed structure can also better protect the built-in power battery; but it also brings the problem of difficult maintenance, especially during the operation of the power battery, its signal, cooling and connecting wires need to be inspected and repaired, and the battery bracket enclosure needs to be completely disassembled before maintenance, which causes a lot of inconvenience to users.

[0029] In order to solve the problem of inconvenience in maintenance caused by the fully enclosed battery bracket in the prior art, the present application provides a new type of power battery bracket, the exemplary structure of which can be referred to as Figures 1 to 4 The power battery bracket provided in this application is used to install power batteries and can be set as a multi-layer structure as needed. Each layer of the bracket is composed of three panels, a bottom plate and a top plate to form a box structure with one side open. The bottom plate is provided with bolt mounting holes. The power battery can be fixedly installed on the bottom plate of each layer by bolts. Usually, at least 2 power batteries can be installed on each layer of the battery bracket. It can be understood that, except for the topmost battery bracket, the top plates of the battery brackets at other levels are the bottom plates of the battery brackets on the previous layer.

[0030] Furthermore, the power battery bracket provided in the present application is also provided with a column and a movable door plate on the opening side, the column is fixedly connected to the upper and lower surfaces of the power battery bracket, specifically, the upper and lower support plates of the column are fixedly connected to the bottom plate and the top plate of the power battery bracket, and the extension plate of the column is detachably connected to the movable door plate, and the specific connection method can be set as needed, such as bolt connection, clamping fixation, etc. It should be noted that the function of the movable door plate is to protect the opening side of the power battery bracket to prevent the built-in power battery from being damaged from the opening side. The movable door plate has been fixed to the column, so the movable door plate can be connected or not connected to the enclosure. Preferably, the movable door plate can be further fixedly connected to the enclosure to enhance the force strength and stability of the opening side of the power battery bracket.

[0031] By setting a semi-enclosed structure with an opening on one side, and setting a column and a movable panel door at the opening, when encountering a problem that the battery needs to be repaired, it is only necessary to remove the movable door panel at the corresponding position. Compared with the fully enclosed closed structure of the prior art, the complete enclosure needs to be removed during maintenance. The semi-enclosed structure provided by the present application greatly improves the maintenance efficiency. On the other hand, the semi-enclosed battery bracket structure provided by the present application has a column set on the opening side, and the column fixes the bottom plate and the top plate, further improving the overall force strength of the power battery bracket.

[0032] In one embodiment, each layer of the power battery rack provided in the present application can install at least two power batteries, and the columns are provided at the dividing lines after the power batteries are installed, and the number of movable door panels on each layer of the battery rack is the same as the number of the power batteries.

[0033] The columns are arranged at the dividing line after the power batteries are installed, and the number of movable door panels on each layer is the same as the number of power batteries. This arrangement ensures that each power battery corresponds to a movable door panel. When maintenance is required, only the movable door panel corresponding to the battery to be maintained needs to be removed, which can improve the maintenance efficiency.

[0034] In one implementation, please refer to Figure 2 and Figure 3 Each layer of the power battery support is a semi-enclosed structure with an open side composed of a surrounding plate, a bottom plate and a top plate. The surrounding plate and the bottom plate are an integrated structure, and the top plate is fixedly connected to the surrounding plate.

[0035] The three panels are welded to the bottom plate as an integrated structure, which has higher strength and is beneficial to improving the overall stress-bearing strength of the power battery bracket; the top plate is fixedly connected to the panels, and the connection method can be set as needed.

[0036] Optionally, a plurality of plug-in parts are provided on the back side of the top plate near the battery bracket of the next layer, and a plurality of bolt holes are provided on the plug-in parts. A plurality of mounting holes are correspondingly provided on the enclosure plate. During installation, the bolt holes of the plug-in parts of the top plate are aligned with the mounting holes of the enclosure plate, and the bolts are inserted to fix them.

[0037] Optionally, the top plate is provided with multiple plug-in parts on the back side of the battery holder of the next layer, and the enclosure is provided with corresponding plug-in interfaces. When installing, the plug-in parts of the top plate are inserted into the plug-in interfaces on the enclosure to achieve the fixing effect; on the other hand, in order to prevent the plug-in parts from sliding in the plug-in interfaces and affecting the overall stability of the battery holder, the size of the plug-in interfaces is set to be slightly smaller than the plug-in parts, so as to achieve an interference fit between the plug-in parts and the plug-in interfaces, and improve the stability after plugging. It is understandable that the depth, length and width of the plug-in interfaces are all smaller than the length, width and height of the corresponding enclosure.

[0038] Optionally, the top plate is provided with a plurality of plug-in parts on the back side near the battery support of the next layer, and the plug-in parts are provided with openings, and the size of the openings is suitable for the enclosure to be inserted into the plug-in parts along the openings to achieve the fixing effect between the two. In order to improve the stability of the top plate and the enclosure after being plugged and fixed, the plug-in parts and the enclosure can be further provided with bolt holes, and after the top plate and the enclosure are plugged and fixed, bolts can be used to further fix them.

[0039] In one embodiment, please refer to Figure 1 The power battery bracket is also provided with four corner columns, and the corner columns are fixedly connected to each layer of the power battery bracket.

[0040] The corner columns are fixed to the outside of the power battery bracket, and each layer of the power battery bracket is fixedly connected, which can better improve the overall strength of the power battery bracket.

[0041] In one embodiment, a hoisting hole is further provided at the upper end of the corner column, and the hoisting hole can facilitate the hoisting and maintenance of the entire power battery bracket.

[0042] On the other hand, the present application also provides a power battery bracket assembly and an electric loader, both of which include the above-mentioned power battery bracket. Therefore, the power battery bracket assembly and electric loader provided by the present application also have the advantages of convenient lifting and maintenance brought by the above-mentioned power battery bracket.

[0043] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
