However, during the driving process of the transfer truck, due to the uneven road surface, the tabletop may become uneven. At this time, it is necessary to level the tabletop.

[0003] The leveling mechanisms on existing transfer trucks are often set between the driving wheels and the vehicle body, which is not convenient to use and will affect the driving or steering of the driving wheels. Summary of the Utility Model

[0004] To overcome the defects of the prior art, the utility model provides a self-leveling electric handling truck, which effectively solves the problem of uneven tabletop of the transfer truck.

[0005] The technical solution for solving the technical problem is: a self-leveling electric handling truck, including a frame. At one end of the bottom of the frame, a driving wheel is provided. At the other end of the bottom of the frame, a steering wheel is provided. Above the frame, a tabletop is provided. A plurality of hydraulic cylinders are fixed on the frame. The telescopic rods of the hydraulic cylinders are fixedly connected to the bottom of the tabletop. The hydraulic cylinders are used to level the tabletop.

[0006] Preferably, a control box is provided at the bottom of the frame. A battery and a controller are provided inside the control box. The controller is electrically connected to the hydraulic cylinders.

[0007] Preferably, the driving wheel includes a motor fixed at the bottom of the frame. The motor is connected to the driving wheel through a drive axle. The middle of the drive axle is rotatably connected to the bottom of the frame.

[0008] Preferably, the steering wheel includes a steering axle provided at the bottom of the frame. The steering wheels are rotatably provided at both ends of the steering axle. The middle of the steering axle is rotatably connected to the frame.

[0009] Preferably, a plurality of height sensors are provided on the tabletop. The height sensors are electrically connected to the controller.

[0010] The structure of the utility model is simple and ingenious, and it is convenient to use. By connecting the frame and the tabletop through the drive axle, the steering axle and a plurality of hydraulic cylinders, the tabletop can be continuously leveled during the driving process, so as to maintain a horizontal state and facilitate the transportation of items.

[0015] The following further elaborates on the specific embodiments of the present utility model in conjunction with the attached drawings.

[0016] As can be seen from Figures 1 to 4 , a self-leveling electric forklift includes a vehicle frame 1. At one end of the bottom of the vehicle frame 1, a driving wheel 2 is provided. The driving wheel 2 includes a motor 7 fixed to the bottom of the vehicle frame 1. The motor 7 is connected to the driving wheel 2 via a drive axle 8. The middle of the drive axle 8 is rotatably connected to the bottom of the vehicle frame 1. At the other end of the bottom of the vehicle frame 1, a steering wheel 3 is provided. The steering wheel 3 includes a steering axle 9 provided at the bottom of the vehicle frame 1. The steering wheel 3 is rotatably provided at both ends of the steering axle 9. The middle of the steering axle 9 is rotatably connected to the vehicle frame 1. Above the vehicle frame 1, a tabletop 4 is provided. A plurality of hydraulic cylinders 5 are fixed to the vehicle frame 1. The telescopic rod of the hydraulic cylinder 5 is fixedly connected to the bottom of the tabletop 4. The hydraulic cylinder 5 is used to level the tabletop 4.

[0017] When the present utility model is in specific use,

[0018] Place an object above the tabletop 4, start the device, the motor 7 drives the driving wheel 2 to rotate, driving the vehicle frame 1 to move forward. At this time, the two driving wheels 2 and the two steering wheels 3 always remain in contact with the ground. Through the structure in which the drive axle 8 and the steering axle 9 are rotatably connected to the vehicle frame 1, when driving on an uneven road surface, the driving wheels 2 or the steering wheels 3 on both sides can adaptively adjust the height to keep the vehicle frame 1 stable. When the deflection between the drive axle 8 / steering axle 9 and the vehicle frame 1 still cannot eliminate the inclination of the vehicle frame 1, the hydraulic cylinder 5 connecting the tabletop 4 and the vehicle frame 1 performs telescopic control, so that the tabletop 4 always remains horizontal, thus successfully completing the handling process.

[0019] A control box 6 is provided at the bottom of the vehicle frame 1. A battery and a controller are provided inside the control box 6. The controller is electrically connected to the hydraulic cylinder 5. A plurality of height sensors are provided on the tabletop 4. The height sensors are electrically connected to the controller.

[0020] The plurality of height sensors are electrically connected to the controller and always transmit height signals to the controller. When the height information received by the controller is inconsistent, it makes a feedback to make the hydraulic cylinder 5 expand and contract to adjust the height of the corresponding position of the tabletop 4, so that the tabletop 4 remains horizontal.

[0021] Compared with the prior art, the utility model has the following beneficial effects: it can always keep the tabletop horizontal during the handling process, realize the automatic leveling function of the tabletop, and has a large body strength, flexible operation and is convenient to use.
