[0002] As an indispensable tool in the field of logistics, transportation and manufacturing, the transporter has been constantly developing and improving. With the advancement and application of electric technology, the all-electric transporter, as a new generation of transport tools, is gradually receiving widespread attention and application.

[0003] A transport truck is a means of transport used to transport goods or articles, and is widely used in factories, warehouses, logistics centers, etc. Traditional transport trucks are usually powered by manpower or partially powered by electricity, while fully electric transport trucks refer to transport vehicles that are completely powered by electricity.

Its use method includes charging, operation control and other steps, and the cargo handling work is completed through the electric drive system. The significance of the all-electric transporter is to improve the handling efficiency, reduce energy consumption, and reduce labor costs, which meets the high efficiency requirements of modern logistics, and also conforms to the development trend of environmental protection and energy saving.

[0005] Currently, all-electric transporters on the market mainly use lithium batteries or other high-performance batteries as energy sources, and are equipped with electric motors or electric hydraulic systems for handling operations. These vehicles have the characteristics of convenient charging, low cost of use, simple operation, environmental protection and energy saving, and are suitable for cargo handling work in various places.

[0006] Although the existing all-electric transport vehicles are technically quite mature, they still have problems such as poor adaptability to different ground surfaces and poor stability. Summary of the invention

[0007] In response to the above technical problems, the utility model provides a fully electric transport vehicle, which has the advantage of strong ground adaptability, especially on uneven ground or slopes, can ensure that the vehicle has good traction and stability during transportation, is not easy to slip or lose control, and improves the applicability and practicality of the vehicle.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] A fully electric transport vehicle comprises a frame and a fork frame. The fork frame is provided with a lifting frame, which is slidably mounted on the frame. A lifting mechanism is arranged inside the frame, and the lifting mechanism lifts the lifting frame to drive the fork frame to perform lifting movements. The fork frame comprises legs, and the legs are provided with a connecting rod mechanism. One end of the connecting rod mechanism is hinged to a load-bearing wheel. When the fork frame performs lifting movements, the connecting rod mechanism drives the load-bearing wheel to roll close to the ground.

[0010] By adopting the above technical solution, the load-bearing wheels are always close to the ground, so that the vehicle can maintain good traction and stability on uneven ground or slopes, and is not easy to slip or lose control. This significantly improves the stability of the transporter in various complex environments and helps to ensure the safety of the transport operation. The setting of the lifting mechanism allows the vehicle legs to flexibly adjust the height to adapt to goods or work scenes of different heights, solving the problem of difficult operation or low efficiency caused by height mismatch. The operating handle set on the frame allows the operator to easily control the movement and operation of the vehicle, reducing manpower consumption and improving operating efficiency. Especially when the height needs to be adjusted frequently or goods of different heights are transported, the enhancement of operational convenience is particularly significant. The compactness of the connecting rod mechanism and the lifting mechanism can also save space in the vehicle and improve the applicability of the vehicle in narrow environments.

[0011] It is further provided that the linkage mechanism includes a lever arm frame, a roller, a connecting rod, and a pull rod fork, the first end of the lever arm frame is hinged to the roller, the second end of the lever arm frame is hinged to the first end of the connecting rod, the second end of the connecting rod is connected to the pull rod fork, and the pull rod fork is hinged to the lever arm block. It is further provided that the lever arm frame is hinged to the vehicle leg, the load-bearing wheel is installed on the lever arm block, the lever arm block is hinged to the vehicle leg, and the lever arm frame is hinged to the vehicle leg.

[0012] By adopting the above technical solution, the connecting rod mechanism can effectively transfer the weight of the goods, and through reasonable articulation and connection methods, it reduces energy loss, improves the efficiency of force transmission, and enables the transport vehicle to operate more stably and efficiently when transporting heavy goods. The structure of the connecting rod mechanism can accurately control the lifting and movement trajectory of the vehicle legs. By adjusting the length or angle of components such as the connecting rod and the pull rod fork, the precise lifting and lowering of the vehicle legs can be achieved to meet the needs of cargo handling at different heights. The components such as the arm frame, roller, connecting rod, pull rod fork and arm block in the connecting rod mechanism form a stable support structure. These components are connected by articulation to form a solid support frame, which can effectively support the vehicle legs and load-bearing wheels, and improve the stability and safety of the entire vehicle. The use of rolling elements such as rollers in the connecting rod mechanism can reduce friction and wear, extend the service life of the mechanism, and improve the smoothness and efficiency of operation.

[0013] It is further arranged that a wear-resistant plate is installed at the bottom of the frame, and the rollers abut against the wear-resistant plate.

[0014] By adopting the above technical solution, the setting of the wear-resistant plate can effectively protect the bottom of the frame from the friction of the rollers and reduce wear. Especially when the vehicle is driving on uneven roads or encounters large friction, the wear degree of the frame can be reduced and the service life of the frame can be extended. The rollers close to the wear-resistant plate can reduce the friction noise and vibration generated when the vehicle is driving, making the transport vehicle run more smoothly and quietly, reducing interference with the surrounding environment and operators, and improving the comfort of the working environment. The rollers close to the wear-resistant plate can reduce the friction resistance of the vehicle when driving and reduce energy loss, thereby improving the driving efficiency and energy utilization of the vehicle, and reducing energy consumption and operating costs.

[0015] It is further provided that the lifting mechanism includes an oil cylinder, a pump station, and an oil pipe, and the oil cylinder is connected to the pump station through the oil pipe; the oil cylinder is located below the lifting frame.

[0016] By adopting the above technical solution, hydraulic lifting is achieved by using oil cylinders, pump stations and oil pipes. Through the operation of the hydraulic system, the lifting and lowering operation of the vehicle legs can be completed quickly and smoothly, thereby improving the operating efficiency of the transporter. The hydraulic system can achieve smooth and controllable operation. The operator can accurately control the operation of the oil cylinder through the operating handle to adjust the lifting height of the vehicle legs. The addition of the hydraulic system enhances the stability of the lifting mechanism. The oil cylinder is located below the lifting frame, which can effectively support the lifting frame and the vehicle legs, reduce shaking and instability during the lifting process, and improve the stability and safety of the entire transporter.

The setting of the limit plate can effectively prevent the lifting system from being damaged due to overload. When the vehicle legs reach the limit position, the limit plate will limit the continued movement of the lifting frame, protect the hydraulic system and mechanical components, and extend the service life of the equipment. The travel switch can also accurately control the end position of the lifting to avoid unnecessary energy waste. When the vehicle legs reach the preset position, the hydraulic system is stopped in time, which saves energy consumption, improves energy utilization, and reduces operating costs. The setting of the travel switch and the limit plate can reduce unnecessary lifting times and overload operations, reduce wear and damage to mechanical components, extend the service life of the equipment, and reduce maintenance costs.
