[0011] In some embodiments of the present application, the wheel frame is an inverted U-shaped structure, balance wheels are installed at both ends of the wheel frame, a driving wheel is installed between the two balance wheels, and the driving wheel is connected to the wheel frame.

[0012] In some embodiments of the present application, the front side of the wheel frame is covered by a fender, and the fender shields the front side of the driving wheel. Adding the fender effectively further protects the driving wheel.

[0013] In some embodiments of the present application, both ends of the wheel frame are connected to the reinforcing rod via a rocker arm. Thus, the present application realizes the integrated connection of the fuselage.

[0014] In some embodiments of the present application, the operating handle, the oil cylinder, and the hydraulic station are arranged in sequence from front to back, and the cover is arranged outside the hydraulic station and between the oil cylinder and the base plate.

[0015] In some embodiments of the present application, the bottom two sides of the cover shell extend forward to form side panels, and the two side panels are respectively located on the left and right sides of the oil cylinder. That is, the cover shell structure in the present application also plays a role in connecting and protecting the oil cylinder, making the product structure stable and high in structural strength.

[0016] In some embodiments of the present application, the top of the frame extends forward to form an extension portion, the extension portion is located above the oil cylinder and the hydraulic station, and the top of the oil cylinder is connected to the extension portion.

The frame 2 constitutes a vertically arranged battery compartment, which constitutes an independent battery installation space. A controller 3 is installed on the frame 2, and a shell is provided on the outer cover of the frame 2. The shell and the frame 2 constitute a relatively independent space for the controller 3. The front of the frame 2 is connected to a wheel frame 4, and a cylinder 5 and an operating handle 6 are installed on the wheel frame 4. A hydraulic station 7 is arranged between the cylinder 5 and the machine body, and a cover 8 is provided on the outer cover of the hydraulic station 7. The present application relatively independently installs the hydraulic station 7 on the outer periphery of the frame 2 and installs it close to the cylinder 5, thereby reducing some connection relationships, making the product structure simple and reliable. Correspondingly, a cover 8 is provided on the outer cover of the hydraulic station 7. The installation space of the cover 8 here is relatively abundant, and the structural requirements are relatively low.

[0026] The electrical system of the electric transport truck mainly involves the oil cylinder 5, the hydraulic station 7, the battery and the controller 3. Unlike the prior art, which concentrates a large number of electrical components in the frame 2, resulting in an excessively large volume of the frame 2, the present application separates and arranges the components of each electrical system and reasonably plans their positions, thereby simplifying the structure and volume of the frame 2, and making the structure more compact and small.

[0027] In this application, for the convenience of description, the Figure 1 The front and rear are defined as a reference, that is, the operating handle 6 is located at the front side of the entire electric transport vehicle.

[0031] The wheel frame 4 is an inverted U-shaped structure, with balance wheels 11 installed at both ends of the wheel frame 4, a driving wheel installed between the two balance wheels 11, and the driving wheel connected to the wheel frame 4. The front side of the wheel frame 4 is covered by a fender 12, and the fender 12 shields the front side of the driving wheel. The addition of the fender 12 effectively provides further protection for the driving wheel. The two ends of the wheel frame 4 are respectively connected to the reinforcing rod 23 through a rocker arm 13. At this point, the application realizes the integrated connection of the fuselage.

[0032] The operating handle 6 , the oil cylinder 5 , and the hydraulic station 7 are arranged in sequence from front to back, and the cover 8 is disposed outside the hydraulic station 7 and between the oil cylinder 5 and the base plate 21 .

[0033] The two sides of the bottom of the cover 8 extend forward to form side panels, and the two side panels are respectively located on the left and right sides of the oil cylinder 5. That is, the cover 8 structure in the present application also plays a role in connecting and protecting the oil cylinder 5, making the product structure stable and high in structural strength.
