Description

Technical Field

[0001] This utility model relates to the field of loader technology, and in particular to a battery frame for a pure electric loader. Background Technology

[0002] Loaders, as earthmoving machinery, are widely used in construction, mining, road construction, and livestock farms. They are primarily used for loading and transporting bulk materials such as sand, gravel, coal, and hay. By changing different attachments, they can also perform bulldozing, dumping, lifting, and stacking operations. Due to their advantages such as fast response time, high efficiency, good maneuverability, and easy operation, they have become one of the main types of machinery used in earthmoving construction projects. With the rapid development of the electric vehicle industry, an electrification trend has emerged in the construction machinery sector. Currently, electric-drive and pure electric construction machinery products have appeared on the market. Electric loaders have emerged as a result, and their sales have been rising steadily in recent years. Due to their low maintenance costs and reliable technology, they have taken a leading position in the industry.

[0003] However, current battery packs are generally characterized by their large capacity and volume, making it crucial to extend the loader's range by arranging more battery packs within a limited space. Given the inherent limitations of the mounting space on the loader's rear frame, developers must carefully consider the battery pack structure and its compatibility with the loader's hood and other structural components during the design process. Under these developmental challenges, how to cleverly utilize the limited installation space to maximize the number of battery packs has become a core problem that urgently needs to be solved. As the mounting carrier for the battery packs, the rationality of the battery frame's structural design has a decisive impact on the number of battery packs the loader can accommodate. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a battery frame for a pure electric loader, used to carry a battery pack. It includes a front battery frame, a middle battery frame, and a rear battery frame installed on the upper part of the rear frame, as well as a lower battery frame installed at the rear counterweight on the lower part of the rear frame. The front battery frame, the middle battery frame, and the rear battery frame each include several detachably connected single-layer battery frames.

[0027] like Figure 1-2 As shown, this utility model discloses a battery frame for a pure electric loader, used to support a battery pack. It includes a front battery frame 2, a middle battery frame 3, and a rear battery frame 4 mounted on the upper part of the rear frame 1, and a lower battery frame 5 mounted on the rear counterweight at the lower part of the rear frame 1. The front battery frame 2, middle battery frame 3, rear battery frame 4, and lower battery frame 5 are structurally independent and do not affect each other. Specifically, the front battery frame 2, middle battery frame 3, and rear battery frame 4 each include several detachably connected single-layer battery frames. The single-layer battery frames are connected to each other via fasteners, and the battery pack is placed inside the single-layer battery frame and connected to it via fasteners.

[0028] In some embodiments, the single-layer battery frame is a box-shaped structure, including a battery mounting base plate. Mounting panels are connected to the four sides of the battery mounting base plate, and one end of each mounting panel away from the battery mounting base plate has an L-shaped bend structure for connection with other adjacent single-layer battery frames. A reinforcing rib structure is provided between the inner sides of two adjacent mounting panels, and lifting mounting holes are provided on two opposing mounting panels. Inspection notches are provided on the mounting panels.

[0029] like Figure 6 As shown, in some embodiments, the lower battery frame 5 is a tray-type structure, placed inside the counterweight compartment of the rear frame 1, and can be used as a counterweight to increase the overall weight, improve the tilting performance of the whole machine, and enhance the stability of the whole machine during operation. Specifically, the lower battery frame 5 includes a counterweight compartment base plate 51 and upright plates 54 spaced apart on the counterweight compartment base plate 51, which horizontally divide the lower battery frame 5 into at least two battery installation spaces. Each battery installation space is provided with a lower battery pack mounting plate 52 fixed to the counterweight compartment base plate 51, and the lower battery pack mounting plate 52 is provided with battery pack mounting holes for fixing the battery pack. Preferably, the upright plates 54 on both sides of the lower battery frame 5 are provided with maintenance ports. The side of the upright plate 54 away from the counterweight compartment base plate 51 is connected to a upper battery pack mounting plate 53 and a reinforcing rib plate 55 for vertically dividing the lower battery frame 5 into two battery installation areas. The upper battery pack mounting plate 53 is provided with battery pack mounting holes for fixing the battery pack.

[0030] Furthermore, the counterweight compartment bottom plate 51 extends obliquely upward at one end in the extension direction of the upright plate 54, with an L-shaped battery pack mounting plate 56 and a fixed mounting base 57 at its end, and a fastener mounting hole for connecting to the rear frame at the other end. The fixed mounting base 57 connects the lower battery frame 5 and the rear frame 1; the L-shaped battery pack mounting plate 56, together with the upper battery pack mounting plate 53 and the reinforcing rib plate 55, forms a battery pack accommodating space. This helps to fully utilize the installation space, maximize the number of battery packs, and enhance the overall range of the vehicle.

The front single-layer battery frame 3 23 is an integrated frame structure with a battery pack inlet at the bottom.

[0033] The specific implementation process of the front battery frame 2 is as follows: the front single-layer battery frame 1 21 is placed at the bottom, and the battery pack is placed inside the front single-layer battery frame 1 21 and fixed to the frame mounting base plate by fasteners. The front single-layer battery frame 2 22 is placed on the front single-layer battery frame 1 21 and connected to the mounting base plate of the front single-layer battery frame 2 22 through the L-shaped bending structure of the mounting panels on both sides of the front single-layer battery frame 1 21. When installing the third layer battery pack, the battery pack is first fixed to the mounting base plate 1 24, then the mounting base plate 1 24 is placed on the front single-layer battery frame 2 22, and finally the front single-layer battery frame 3 23 is inverted to cover the battery pack, and then connected to the mounting base plate 1 24 by fasteners 7. Throughout the installation process, the battery pack is fixedly connected to the battery frame by fasteners 7. The single-layer front battery frame 323, with its bottom-opening integrated frame structure, not only ensures the strength of the battery frame but also provides adjustment space around its top. In addition, the single-layer front battery frame 323 can also be used as a mounting carrier for other electrical components.
