[0029] Example 1

[0030] like Figure 1 As shown, this embodiment discloses a power battery frame for use in a welded counterweight of an electric loader. The frame utilizes a layered mounting structure and includes a base plate 1, a vertical plate, and a battery mounting plate. Both the base plate 1 and the battery mounting plate are provided with multiple battery mounting holes. During installation, the battery is secured to the base plate 1 and the battery mounting plate using bolts passing through the battery mounting holes. For example, bolts with model number GBT16674.1-M12X40-10.9-DC can be used to secure the battery to the base plate and the battery mounting plate.

[0031] The vertical plates include a first vertical plate 2 and a second vertical plate 3, welded to either side of the base plate 1. Both the first and second vertical plates are T-shaped plates with bends at both ends, which effectively reduce concentrated stress at the weld points between the base plate 1 and the vertical plates, thereby improving the reliability and safety of the power battery frame.

[0032] The battery mounting plate includes a first battery mounting plate 4, a second battery mounting plate 5, and a third battery mounting plate 6. The first battery mounting plate 4 is mounted atop the first and second vertical plates 2 and 3, and is used to mount the first power battery. The second and third battery mounting plates 5 and 6 are mounted between the first battery mounting plate 4 and the base plate 1. The second and third battery mounting plates 5 and 6 are mounted on the same mounting surface, and are respectively mounted with the second and third power batteries. A battery compartment is formed between the second and third battery mounting plates 5 and 6 and the base plate 1, accommodating the fourth and fifth power batteries mounted on the base plate 1. By configuring the power battery frame in a tiered mounting configuration, five power batteries can be accommodated within the power battery frame within the electric loader's welding counterweight, meeting the electric loader's 433 kWh power requirement. The power battery frame adopts a 2-2-1 arrangement from bottom to top, which optimizes the spatial arrangement of the five power batteries and improves space utilization within the welding counterweight.

[0033] In this embodiment, the battery mounting plate has connecting portions on both sides, which are perpendicular to the battery mounting plate and are fixedly connected to the first vertical plate 2 and the second vertical plate 3, respectively. Specifically, the connecting portion of the battery mounting plate is provided with a plurality of fixing holes. At the same time, the first vertical plate 2 and the second vertical plate 3 are provided with a plurality of fixing holes opposite to the connecting portion of the battery mounting plate. Bolts 12 are inserted through the corresponding fixing holes to secure the battery mounting plate.

[0034] In this embodiment, three groups of fixing holes are provided on each connecting portion of the battery mounting plate, with two fixing holes forming a group, which can ensure that the battery mounting plate is firmly mounted on the frame.

[0035] In this embodiment, a plurality of base plate mounting holes 11 are further provided on the base plate 1. After the power battery is assembled, the base plate 1 is fixed to the bottom cover (not shown in the figure) by bolts.

[0036] In this embodiment, a wiring harness fixing plate 8 is welded to one side of the second battery mounting plate 5 and the third battery mounting plate 6 for fixing the wiring harness of the power battery. During installation, the side with the wiring harness fixing plate 8 is located on the outside, that is, the sides of the second battery mounting plate 5 and the third battery mounting plate 6 without the wiring harness fixing plate 8 are close to each other, and the sides with the wiring harness fixing plate 8 are welded to each other. At the same time, a number of threaded seats 9 are provided on the first vertical plate 2 for fixing the wiring harness of the power battery, so that the wiring harness of the power battery is organized and easy to inspect and maintain. During installation, the threaded seats 9 can also distinguish between the first vertical plate 2 and the second vertical plate 3, ensuring that the second vertical plate 3 is installed towards the rear of the vehicle.

[0037] Multiple windows are featured on the base plate 1, vertical plates, and battery mounting plate. Without compromising strength, these windows can effectively reduce the weight of the power battery frame, achieving weight reduction. Furthermore, the windows simplify and streamline the routing of the power battery wiring harness.

[0038] In this embodiment, both ends of the top of the first vertical plate 2 and the second vertical plate 3 are further provided with hoisting holes. After the power battery is assembled, it is hoisted to the bottom cover of the welded counterweight through the hoisting holes for installation.

[0039] In this embodiment, the bottom plate 1 and the vertical plate are made of 12 mm thick steel plates, and the battery mounting plate is made of 10 mm thick steel plates, which can ensure the strength of the power battery frame and improve the reliability and safety of the power battery frame.

[0040] When assembling the power batteries, first install two power batteries on the base plate 1, one power battery on the first battery mounting plate 4, one power battery on the second battery mounting plate 5, and one power battery on the third battery mounting plate 6, then fix the second battery mounting plate 5 and the third battery mounting plate 6 on the vertical plate, and then install the first battery mounting plate 4 on the top of the vertical plate. At the same time, organize the wiring harness of the power battery and fix it on the wiring harness fixing plate 8 and the threaded seat 9 respectively; the lifting mechanism lifts the assembled power battery assembly to the top of the bottom cover of the electric loader's welded counterweight through the lifting hole 10, ensuring that the first vertical plate 2 is facing the rear of the vehicle, and then fixes it to the bottom cover through the bottom plate mounting hole 11 on the base plate 1.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
