Description

Technical Field

[0001] This utility model belongs to the field of battery installation technology for transport vehicles, and specifically relates to a battery assembly installation structure for an electric transport vehicle. Background Technology

[0002] Electric pallet trucks, powered by batteries, are widely used in industrial production, warehousing, and logistics. In existing technologies, some battery components are enclosed within the battery compartment of the pallet truck, and the battery compartment cover is locked using complex fastening mechanisms. This makes battery replacement or repair cumbersome, time-consuming, and labor-intensive. Furthermore, while pallet trucks often incorporate multiple battery components to increase range, the current design results in a less compact overall structure and poorer stability.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a small electric pallet truck [201220551277.X], which includes a frame, symmetrical forks located at the front of the frame, and a load-bearing wheel rocker arm frame mechanism mounted in front of the bottom of the forks. A drive wheel driven by a motor is located at the rear of the frame, and a slewing bearing is located above the drive wheel. An operating handle is located on the drive wheel housing. The slewing bearing is used to rotate the operating handle to achieve steering. A power supply box is located on the frame, and a battery is located inside the power supply box. Above the battery is a built-in charger connected to a controller and a hydraulic pump station system assembly. The hydraulic pump station system assembly controls the lifting and lowering of the forks. The battery supplies power to the controller, motor, and hydraulic pump station system assembly. An accelerator and an emergency reverse controller are located on the operating handle.

[0004] The above solution has solved to some extent the problem of cumbersome operation when replacing or repairing batteries due to the existing battery components being enclosed and installed in the battery box of the transport vehicle. However, the solution still has many shortcomings, such as the fact that installing multiple battery components will make the transport vehicle less compact overall. Summary of the Invention
