[0003] 1) The integrated design of the oil cylinder and the operating handle may increase the weight of steering, affecting the mobility and energy efficiency of the forklift, and restricting the operating flexibility. Because the position of the operating handle and the movement of the oil cylinder are fixed and cannot be adjusted according to the needs of the operator, and the service life of the oil cylinder is short;

[0004] At the same time, the connecting part between the oil cylinder and the operating handle may be worn or damaged due to frequent use, affecting the overall durability. The integrated design increases the design complexity and requires more engineering design and testing to ensure its reliability;

[0005] 2) The integrated design will increase the manufacturing cost. It is necessary to design and manufacture a more complex connecting structure, making maintenance and repair more complicated, greatly increasing the cost and time, especially when the oil cylinder or the operating handle needs to be replaced separately; if the oil cylinder or the operating handle fails, it takes more time to diagnose the problem. Summary of the Invention

A convex portion is provided at the left end of the pedestal, and some of the screw holes are formed in the convex portion. The right end surface of the pedestal is an inclined surface.

[0010] Further, a ring body is provided on the inner wall of the mounting hole. A circular notch is provided on the lower end surface of the ring body, and the circular notch is formed along the inner wall edge of the ring body.

[0011] Further, extension portions extending outward are provided at both ends of the mounting hole.

[0012] Further, the width W of the pedestal is greater than the sum of the diameter D1 of the mounting seat at the extended end of the cylinder and the diameter D2 of the mounting hole of the connection assembly.

[0013] Further, the central axis of the cylinder and the central axis of the connecting shaft in the connection assembly are on the same straight line.

[0014] Further, pedestal lower arms are provided on both the front and rear sides of the pedestal, and the lower ends of the pedestal lower arms are connected to the lifting rods.

[0015] Advantages of the present utility model:

[0024] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0025] As Figures 1 to 4 shown, an electric forklift truck with a split power transmission structure includes a pedestal 1. Lower arms 12 of the pedestal 1 are provided on both the front and rear sides of the pedestal 1, and the lower ends of the lower arms 12 of the pedestal are connected to a lifting rod 13. An operating handle 2 and an oil cylinder 4 are respectively installed on the plate surface of the pedestal 1. There is a gap between the operating handle 2 and the oil cylinder 4, forming a split structure between the operating handle 2 and the oil cylinder 4. The upper end of the oil cylinder 4 is connected to the battery compartment 5 through an oil cylinder seat; a drive assembly 3 is installed below the pedestal 1, and the operating handle 2 and the drive assembly 3 are connected through a connection assembly.

[0026] At the same time, the extending end of the oil cylinder 4 is connected to the pedestal 1, and the fixed end of the oil cylinder 4 is connected to the battery compartment 5.

[0027] As Figures 3 to 4 shown, mounting holes 7 for installing the connection assembly and a number of screw holes 6 for installing the oil cylinder 4 are provided on the plate surface of the pedestal 1. The left end of the pedestal 1 has a protrusion 8, and some of the screw holes 6 are provided on the protrusion 8. The right end face of the pedestal 1 is an inclined plane.

[0028] A ring body 9 is provided on the inner wall of the mounting hole 7, and an annular notch 10 is provided on the lower end face of the ring body 9, and the annular notch 10 is provided along the inner wall edge of the ring body 9. Extension parts 11 extending outward are provided at both ends of the mounting hole 7.

[0029] As Figure 2 shown, the width W of the pedestal 1 is greater than the sum of the diameter D1 of the mounting seat at the extending end of the oil cylinder 4 and the diameter D2 of the mounting hole of the connection assembly, further increasing the width of the pedestal 1 and improving the strength of the pedestal 1. At the same time, as Figure 3 described, it can be seen that the pedestal 1 is a flat plate, which is convenient and simple to process, has a high processing efficiency, and can also ensure the working strength.

[0030] The central axis of the oil cylinder 4 and the central axis of the connecting shaft in the connection assembly are on the same straight line, so as to realize the split design between the oil cylinder 4 and the operating handle 2, and ensure that the oil cylinder 4 and the operating handle 2 are installed on the same axis without affecting the use of the oil cylinder 4 and the operating handle 2.

[0031] Specifically:

[0032] First, the oil cylinder 4 is installed in an inverted manner, with the fixed end of the oil cylinder 4 facing upward and the extending end facing downward. The extending end of the oil cylinder 4 is installed on the pedestal 1 through the mounting seat to complete the installation of the oil cylinder 4.

[0033] Then, install the connection assembly in the mounting hole 7. The lower end of the connection assembly is connected to the drive assembly 3, and the upper end of the connection assembly is connected to the operation handle 2. There is a certain gap between the oil cylinder 4 and the operation handle 2, thereby improving the heat dissipation performance of the oil cylinder 4.

[0034] Finally, during use, the operator starts the drive motor in the drive assembly 3 through the control handle 2 to make the vehicle start to move.

[0035] When steering, the operator controls the steering of the front wheels by controlling the steering rod or button on the operation handle 2, without connecting the oil cylinder 4, to achieve a left or right turn of the vehicle.

[0036] When lifting or lowering the forklift forks, the operator controls the oil cylinder 4 by controlling the lift control rod or button on the operation handle 2 to raise or lower the forklift forks so as to pick up or put down goods.

[0037] Inspired by the above ideal embodiments according to the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
