[0024] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1 to 5 As shown, this embodiment provides a narrow battery box that is easy to maintain from the side, including a box shell, the box shell has a first end 101 and a second end 102 opposite to each other along the length direction. Specifically, in this embodiment, the box shell is a rectangular shell formed by splicing an upper cover 11, a bottom cover 12, a left side plate 13, a right side plate 14, a battery end cover 15 located at the first end 101, and an electric control end cover 16 located at the second end 102. The length dimension of the box shell is large and the width dimension is small, so that a narrow battery box is formed. Of course, in other embodiments, the composition structure of the box shell is not limited to this.

[0026] The box housing is formed with a battery receiving chamber 1 near the first end 101 and an electric control receiving chamber 2 near the second end 102. The battery receiving chamber 1 is used to install the battery module, and the electric control receiving chamber 2 is used to install the electric control part. The electric control end cover 16 at the second end 102 of the box housing is detachable, so that an electric control receiving chamber 2 with a lateral opening can be obtained by removing the electric control end cover 16. Figure 2 shown.

[0027] This embodiment also provides a forklift battery, including a battery box, a battery module and an electronic control part, characterized in that: the battery box is the narrow battery box mentioned above that is easy to maintain from the side, the battery module is assembled in the battery accommodating cavity 1, and the electronic control part is assembled in the electronic control accommodating cavity 2.

[0028] Specifically, the battery module and the electronic control part all adopt the existing technology, and their components and connection methods have long been mastered by technicians in this field, so they will not be described in detail here.

[0029] This embodiment also provides a forklift, specifically a forward-moving electric forklift or a forklift with a forward-moving function. The forklift includes a forklift body and a battery, the battery is mounted behind the seat front door frame of the forklift body, and the battery is the forklift battery described above.

[0030] By adopting the solution provided in the present application, when the electronic control part needs to be maintained, it is only necessary to remove the electronic control end cover 16 from the side, and an opening directly to the electronic control part can be opened from the second end 102 of the battery box, so that the electronic control part can be maintained conveniently without moving the battery. The operation is simple, the maintenance time is shortened, and manpower and material resources are saved.

[0031] Specifically, the electric control end cover 16 is locked by bolts to form a detachable assembly. In this embodiment, the electric control end cover 16 is locked by seven bolts, namely, the top of the electric control end cover 16 is locked on the upper cover 11 by one bolt, and the left and right sides of the electric control end cover 16 are respectively locked on the left plate 13 and the right plate 14 by three bolts; when it is necessary to assemble or disassemble, just install or remove these seven bolts, and the operation is relatively simple. Of course, in other embodiments, the electric control end cover 16 can also be installed by other detachable fixing methods such as snap-on, plug-in, etc.

[0032] Meanwhile, for the convenience of operation, the outer side of the electric control end cover 16 is also equipped with a handle 161, and it is more convenient to take out the electric control end cover 16 by grabbing the handle 161, and the operation is more convenient. Of course, other structures that are conducive to grabbing can also be provided.

[0033] The electric control accommodating chamber 2 is also equipped with an electric control mounting bracket 20 for mounting the electric control part; specifically, the electric control mounting bracket 20 includes an electric control bracket 21, a BMU bracket 22 and a support bracket 23; wherein, the electric control bracket 21 includes a first side plate 211 and a second side plate 212 which are perpendicular to each other, the first side plate 211 is arranged directly opposite to the electric control end cover 16, the second side plate 212 is arranged perpendicular to the electric control end cover 16, the support bracket 23 is fixed on the first side plate 211, and the BMU bracket 22 is fixed on the second side plate 212. The first side plate 211 is also used to mount the contactor, fuse and DC-DC converter of the electric control part; the support bracket 23 is used to mount the relay and the shunt; in this way, the contactor, fuse, DC-DC converter, relay and shunt can all face the electric control end cover 16, and can face the opening after the electric control end cover 16 is removed, which is convenient for maintenance operations. However, the BMU (battery management unit) has large length and width dimensions, so it can only be placed sideways on the BMU bracket 22; in this way, the various components of the electronic control part can be reasonably laid out and installed, saving space and being more conducive to maintenance.

[0034] At the same time, the upper cover 11 includes a battery upper cover 111 enclosing a battery accommodating cavity 1 and an electric control upper cover 112 enclosing an electric control accommodating cavity 2. The battery upper cover 111 is detachable, which is conducive to assembling the battery module.

[0035] Further preferably, the left side plate 13 (or the right side plate 14) has an upper notch 131, so that when the battery cover 111 is removed, a battery receiving chamber 1 with an L-shaped opening is obtained, thereby increasing the opening of the battery receiving chamber 1, which is more conducive to the operation of taking and placing the battery module. The battery cover 111 has an L-shaped structure and can be detachably covered on the L-shaped opening of the battery receiving chamber 1, so that a complete covering assembly is achieved.

[0036] Specifically, a module bracket 30 is fixed in the battery accommodating chamber, and the module bracket 30 divides the battery accommodating chamber 1 into two upper and lower installation chambers. In this embodiment, each layer of the installation chamber can store two battery modules, and the upper and lower layers can store a total of four battery modules, and the spatial layout is reasonable. More specifically, the module bracket 30 is supported by a plurality of welding brackets 31 fixed on the inner wall of the battery accommodating chamber 1.

[0037] Through the above technical solution provided in this embodiment, the width dimension W of the battery can be reduced to 211 mm; the width dimension is greatly reduced without affecting the module assembly, thereby saving the working space of the reach forklift and improving the utilization rate of the warehouse space.

[0038] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
