[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] As an important type of engineering machinery, loaders are widely used in logistics, construction, mining and other fields. With the continuous development of new energy technologies, more and more manufacturers have begun to apply electric technology to loaders, and the electricity is converted into mechanical energy through the motor to drive the operation of various systems. At the same time, electric loaders can achieve zero emissions and low operating costs during operation, making the development of electric loaders even more rapid.

[0004] The battery life of an electric loader depends on the number of power batteries installed. In order to ensure that the electric loader has sufficient battery life, a corresponding counterweight structure is usually installed on the side of the frame, and a sufficient number of batteries are arranged on the counterweight structure to ensure the stability of the frame and the sufficient battery life of the electric loader.

[0005] However, the above method still limits the number of power batteries arranged on the counterweight structure. When the number of power batteries is large, the weight of the counterweight structure itself and the power batteries will also affect the stability of the frame, and there is a risk of the counterweight structure falling off the frame, affecting the use of the electric loader.

[0026] The following is combined with Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0027] Example 1

[0028] A power battery frame structure for an electric loader is used for being installed on a frame 1 of the electric loader.

[0029] Reference Figure 1-2 , a power battery frame structure of an electric loader, including a welded counterweight shell 2, a lower power battery frame assembly 4, an upper power battery frame 3 and a battery mounting plate 9.

[0030] Reference Figure 1 and Figure 3The welded counterweight housing 2 is a shell structure formed by welding the upper base plate, charging socket plate, and reinforcing ribs. This allows the welded counterweight housing 2 to not only serve as a counterweight but also facilitate other functions such as wiring. The welded counterweight housing 2 is also fixedly connected to the side of the vehicle frame 1 by welding.

[0031] Reference Figure 2 The lower power battery frame assembly 4 includes a lower power battery frame 5 and a welded bottom cover 6.

[0032] The lower power battery frame 5 is arranged inside the welded counterweight shell 2 , and the lower power battery frame 5 and the welded counterweight shell 2 are fixedly connected via a welded bottom cover 6 .

[0033] Reference Figure 4-6 The welded bottom cover 6 is also welded by different steel plates, and the bottom of the welded bottom cover 6 is a double-layer cover structure, and the wide side length of the upper cover is longer than the wide side length of the lower cover, thereby ensuring that the side of the welded bottom cover 6 is in an inclined state, thereby facilitating the fixation and support of the lower power battery frame 5, and at the same time facilitating the fixed connection between the welded bottom cover 6 and the frame 1 and the welded counterweight shell 2 to form a complete structure.

[0034] Reference Figure 1-2 The lower power battery frame 5 is fixedly mounted on the upper cover plate of the welded bottom cover 6 via a shock absorber 7. The side of the welded bottom cover 6 is fixedly connected to the upper bottom surface of the inner surface of the welded counterweight housing 2 via bolts. Simultaneously, the side of the welded bottom cover 6 opposite the tilted side is also fixedly connected to the vehicle frame 1 via bolts, ultimately firmly securing the welded bottom cover 6 within the welded counterweight housing 2. Based on the fixed connection between the lower power battery frame 5 and the welded bottom cover 6, the lower power battery frame 5 is also firmly mounted within the welded counterweight housing 2. In this embodiment, a battery mounting plate 9 is provided on the lower power battery frame 5 to provide space and position for the installation of the power battery.

[0035] Through the above arrangement, based on the weight of the welded counterweight shell 2, the lower power battery frame assembly 4 and the power battery installed on the lower power battery frame 5, the stability of the frame 1 can also be ensured, thereby replacing the original counterweight block; at the same time, additional space and position are provided for the installation of the power battery, ensuring that the electric loader has sufficient endurance.

[0036] In order to further ensure the stability of the welded bottom cover 6 inside the welded counterweight shell 2, a safety pin 8 is provided on the side where the welded bottom cover 6 contacts the welded counterweight shell 2, and is fixedly connected to the welded counterweight shell 2 through the safety pin 8; at the same time, the safety pin 8 also facilitates the installation and replacement of the welded bottom cover 6.

[0037] While installing the power batteries on the lower power battery frame 5 within the welded counterweight housing 2 can improve the electric loader's endurance, the number of power batteries that can be installed is still limited. This is because installing a large number of batteries on the lower power battery frame 5 results in a heavy load at that location, affecting the stability of the vehicle frame 1. Furthermore, over time, the connection between the welded counterweight housing 2 and the vehicle frame 1 may become loose or damaged, creating the risk of the welded counterweight housing 2 falling off.

[0038] In order to prevent the welded counterweight housing 2 from falling off and further increase the number of installed power batteries, this embodiment adopts the following solution:

[0039] An upper power battery frame 3 is arranged above the vehicle frame 1 and the welded counterweight shell 2, and the upper power battery frame 3 is fixedly connected to the upper surface of the vehicle frame 1 and the welded counterweight shell 2 through the shock absorber 7. At the same time, a corresponding number of battery mounting plates 9 are also arranged on the upper power battery frame 3 to provide corresponding space and position for the installation of the power battery.

[0040] By setting up the upper power battery frame 3, when the number of power batteries installed on the lower power battery frame 5 is large and the weight is large, the upper power battery frame 3 can play a tightening role on the welded counterweight shell 2 and the lower power battery frame 5, thereby reducing the force of the welded counterweight shell 2 and the lower power battery frame 5 on the frame 1, thereby avoiding the problem of falling off between the frame 1 and the welded counterweight shell 2.

[0041] At the same time, by installing the power battery in the upper power battery frame 3 above the frame 1, and combining the weight of the upper power battery frame 3 and the power battery, and utilizing the upper power battery frame 3 above the welded counterweight shell 2 to conduct force, the force exerted by the welded counterweight shell 2 and the lower power battery frame 5 on the frame 1 can be further reduced, further reducing the risk of the welded counterweight shell 2 falling off the frame 1.

[0042] Through the above arrangement, a ring connection is formed between the vehicle frame 1, the upper power battery frame 3, the welded counterweight shell 2, the lower power battery frame 5 and the welded bottom cover 6. Compared with the linear connection between the vehicle frame 1 and the welded counterweight shell 2 in the prior art, the technical solution described in this embodiment can further improve the stability between the vehicle frame 1 and the welded counterweight shell 2; at the same time, by installing power batteries at two positions of the upper power battery frame 3 and the lower power battery frame 5, the endurance of the electric loader is further improved.

[0043] In this embodiment, a certain number of weight-reducing holes are opened on the battery mounting plate 9 in order to further increase the number of power batteries while ensuring that the power batteries can be fixed and that the frame itself has sufficient bearing capacity.

[0044] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
