[0031] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0032] In the prior art, in order to save the overall vehicle assembly space, usually the "battery + counterweight" is integrated at the rear of the vehicle, that is, the battery is installed inside the counterweight. However, such a setting also brings many problems, such as the problems of inconvenient charging and maintenance.

[0033] In view of this, the present application provides a new battery assembly method and a battery box. The exemplary assembly method can be referred to Figure 1 , the battery and the counterweight are separated and independently assembled. The rear frame is designed with a semi-enclosed battery assembly space. When assembling, the battery is first installed in the battery assembly space of the rear frame. However, due to the limited assembly space, only part of the battery can be installed inside the frame under normal assembly, and part will be exposed outside the frame. Therefore, a battery box needs to be designed to assemble and protect the battery exposed outside the frame.

[0034] Please refer to Figure 2 And Figure 3 , the present application provides a battery box for assembling the battery of the above battery assembly method, that is, for assembling and protecting the battery exposed outside the frame. Specifically, it includes:

[0035] A box body, on one side of the box body facing the battery, there is an opening, and the opening is suitable for the battery to pass through and be assembled inside the box body;

[0036] A charging door, the charging door is hinged and installed at a second opening, and the second opening is arranged on the side cover plate of the box body on the side far from the battery.

[0037] It can be understood that the box body is the main part of the battery box and is used to accommodate and assemble the battery. The above battery assembly method has been described. When assembling the battery, it is necessary to first assemble the battery onto the frame, and then assemble the battery box corresponding to the battery exposed outside the frame. After the battery box and the battery are assembled correspondingly, it is further fixed to the frame. One side of the battery box facing the battery is provided with a first opening, that is, when the battery box and the battery are assembled correspondingly, the side of the battery box that first contacts the battery is provided with a first opening so that the battery can be normally assembled into the battery box, and the design of the first opening must be suitable for the normal assembly of the battery.

[0038] On the other hand, the battery box provided by the present application is also designed with a charging door, which is installed on the battery box. When charging the battery is required, the charging door is opened and the power cord is connected. Preferably, the charging door is hingedly installed at the second opening of the side cover plate on the side of the battery box away from the battery. The hinged installation method makes the opening and closing of the charging door more convenient. Optionally, a sealing gasket can be provided between the charging door and the side cover plate to improve the sealing effect of the charging door.

[0039] In one embodiment, please refer to Figure 4 , the side cover plate is provided with a first magnetic attraction component and a second magnetic attraction component. The first magnetic attraction component is used to adsorb the charging door after it is closed. The gap between the charging door and the first magnetic attraction component after it is closed is less than 2 mm. The second magnetic attraction component is used to adsorb the charging door after it is opened. The gap between the charging door and the second magnetic attraction component after it is opened is less than 2 mm.

[0040] The magnetic attraction components are mainly used to adsorb the charging door. The first magnetic attraction component can adsorb the charging door after it is closed to prevent the charging door from accidentally opening due to vehicle body vibration. The second magnetic attraction component can adsorb the charging door after it is opened so that the charging door can maintain an open state, facilitating operations such as charging by the user. Regarding the specific selection of the magnetic attraction components, as long as the normal adsorption function can be achieved, common magnetic attraction components such as magnets, electromagnetic chucks, electro-permanent magnetic chucks, etc.

[0041] Preferably, the first magnetic attraction component is installed at the lower inner side of the side cover plate to ensure that the charging door can be normally closed and at the same time provide a certain adsorption force. There is a certain gap between the charging door and the first magnetic attraction component after it is closed. The setting of the gap mainly considers the protection of the magnetic attraction component and the charging door to prevent strong collisions and damage between the two due to the magnetic attraction effect. The size of the gap can be set according to the adsorption force of the specific magnetic attraction component and the difference in the specific installation position, such as set to 1 mm, 2 mm, 3 mm, etc.

[0042] It can be understood that the second magnetic attraction component is used to provide an adsorption force for the charging door after it is opened. Therefore, the second magnetic attraction component must be set at the position where the charging door and the side cover plate are close to being attached after the charging door is opened and flipped, so that the second magnetic attraction component can play a normal adsorption role for the charging door after it is opened. There is also a gap between the second magnetic attraction component and the charging door after it is opened. The specific setting of the gap can refer to the first magnetic attraction component and will not be repeated here.

[0043] In one embodiment, please refer to Figure 4 , the charging door is provided with an anti-collision rubber plug, which is used to prevent the charging door from directly colliding with the side cover plate after it is opened, and at the same time can also keep a certain gap between the charging door after it is opened and the second magnetic attraction component.

[0044] In one embodiment, please refer to Figure 4 , the charging door is further provided with a concave handle. The concave design can provide a certain degree of protection for the handle. Compared with the handle protruding from the outer surface of the charging door, the concave handle is not easily knocked and damaged during vehicle operation.

[0045] In one embodiment, please refer to Figure 2 , the box body further includes a footrest. The side cover plate is provided with a concave portion, and the footrest is arranged in the concave portion of the side cover plate.

[0046] Preferably, the footrest is foldable. The footrest is arranged in the concave portion of the side cover plate. When the footrest is not needed, it can be folded and hidden in the concave portion of the side cover plate to prevent the protruding footrest from colliding with other components unnecessarily.

[0047] For an exemplary structure of the footrest, reference can be made to Figure 5 , the footrest includes a mounting portion and a rotating portion. The mounting portion is fixed to the side cover plate, and the rotating portion is rotatably connected to the mounting portion. When the footrest is not needed, the rotating portion can be rotated for storage and folding. Further, the mounting portion and the rotating portion can be provided with mutually cooperating clamping components or magnetic components. For example, a clamping portion can be provided on the mounting portion, and a clamping groove can be provided on the rotating portion. The clamping portion and the clamping groove cooperate with each other so that the rotating portion can be relatively stably fixed in the concave portion of the side cover plate after being folded and is not easily detached. When the footrest is needed, the clamping component can be opened.

[0048] In one embodiment, reference can be made to Figure 1 and Figure 2 , a plurality of lifting rings are provided at the upper end of the box body, and the lifting rings are used for lifting the box body. Since the weight of the box body is relatively large, equipment is required for lifting during assembly. Therefore, lifting rings are provided at the upper end of the box body. The number of lifting rings is preferably 4, which are distributed at the four corners of the upper end of the box body to improve the stability during lifting.

[0049] In one embodiment, reference can be made to Figure 1 and Figure 2 , the box body further includes an upper surface cover plate, and both the upper surface cover plate and the side cover plate are detachably mounted on the box body. It should be noted that the above-mentioned lifting rings are not provided on the upper surface cover plate, that is, the disassembly of the upper surface cover plate does not affect the normal lifting of the box body. Both the upper surface cover plate and the side cover plate are detachably mounted on the box body so that when the battery needs to be repaired, the user can disassemble the upper surface cover plate or the side cover plate to repair the internally assembled battery.

[0050] On the other hand, the present application also provides a battery assembly structure and an electric wheel loader. The battery assembly structure and the electric wheel loader are equipped with any one of the above battery boxes, so they also have various advantages brought by the above battery boxes.

[0051] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
