[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] This embodiment provides a stand-up electric dump truck, such as Figures 1 to 21As shown, it includes a chassis 1, a dump bucket 2, a handlebar 3, a universal joint 4 and an articulation assembly 5. The chassis 1 is provided with a steering wheel mounting plate 11, a dump bucket supporting plate 12 and a standing pedal 13 in sequence at the front end, the middle part and the rear end along the length direction of the vehicle body. A steering wheel 14 is mounted on the steering wheel mounting plate 11, and a driving wheel 15 located below the standing pedal 13 is mounted on the chassis 1. The articulation assembly 5 includes a double-ended connecting rod 51, which includes a first articulation joint and a second articulation joint located at both ends respectively, the first articulation joint is articulated with the front end of the dump bucket 2, the second articulation joint is articulated with the chassis 1, and the second articulation joint is articulated with the chassis 1 at a position close to the front end of the dump bucket supporting plate 12, and the articulation axes of the first articulation joint and the second articulation joint are both arranged horizontally and perpendicular to the length direction of the vehicle body. The bucket 2 is usually placed on the bucket support plate 12, that is, the bottom of the bucket 2 is placed on the bearing surface (top surface) of the bucket support plate 12. When dumping the materials in the bucket 2, the bucket 2 is turned forward, and the first hinge joint of the double-headed connecting rod 51 will be lowered, and the bucket 2 will move forward and tilt as a whole until the front end of the bucket 2 is against the front end of the vehicle chassis 1, completing the dumping of the bucket 2. The handlebar 3 includes a grip 31 and a steering column 32. One end of the steering column 32 is connected to the steering wheel 14 through a universal joint 4, and the other end of the steering column 32 is fixedly connected to the grip 31. The bucket 2 is provided with a through hole for the steering column 32 to pass through, and a rotating bearing 33 is installed in the through hole. The outer ring of the rotating bearing 33 is fixedly connected to the through hole, and the inner ring of the rotating bearing 33 is fixedly connected to the steering column 32. Preferably, the steering wheel mounting plate 11 is tilted so that the steering column 32 is tilted toward the rear end of the vehicle chassis 1 so that the handle 31 is extended to a position where the driver standing on the standing pedal 13 can hold it.

[0049] Working principle:

[0050] ① Walking stage: The driver stands on the standing pedal 13, holds the two handles 31 on the steering column 32 with both hands, and starts the drive wheel 15 to drive the entire standing-riding electric dump truck forward. By rotating the handle 31 to drive the steering column 32, the steering wheel 14 can be driven to rotate through the universal joint 4 to achieve the steering of the standing-riding electric dump truck. Because the steering wheel 14 is located at the front end of the standing-riding electric dump truck and the drive wheel 15 is located at the rear end of the standing-riding electric dump truck, the steering method of this standing-riding electric dump truck is a positive steering method, which conforms to the driving habits of ordinary people and significantly reduces the learning cost of driving. Moreover, when the dump truck 2 is unloaded, the person stands behind the standing pedal 13, and the center of gravity of the entire vehicle body is concentrated on the drive wheel 15, so that the drive wheel 15 will not idle or "slip". In addition, the handlebar 3 is arranged at the front end, which will not take up extra space in the length of the vehicle body. That is, the main space occupied by the standing pedal 13 and the dump bucket 2 in the length of the vehicle body at present, compared with the existing layout of sit-down electric dump trucks (the main space occupied by the seat, handles and dump bucket in length), the space occupied by the handlebar 3 can be saved, thereby relatively reducing the length of the vehicle body, which is suitable for entering and exiting narrow and flat sites, especially elevators on construction sites.

[0051] ② Dumping stage: After driving the stand-on electric dump truck to the dumping site, lift the dump bucket 2 forward. Under the action of the articulated assembly 5, the dump bucket 2 will move forward and tilt as a whole. At the same time, under the action of the universal joint 4, the steering column 32 of the handlebar 3 will tilt forward together with the dump bucket 2 until the front end of the dump bucket 2 rests against the front end of the chassis 1, completing the dumping of the dump bucket 2.

[0052] In this embodiment, Figures 1 to 21 As shown, the universal joint 4 can be a cross-axis universal joint, a ball-fork universal joint or a ball-cage universal joint. Preferably, a cross-axis universal joint is adopted, and the cross-axis universal joint adopts the existing setting mode.

In this way, rotating the steering column 32 left and right will drive the first U-shaped shaft fork 41 to twist left and right, and then the first hinge shaft 43 will drive the second hinge shaft 44 to twist left and right, and the second hinge shaft 44 will drive the second U-shaped shaft fork 42 to twist left and right, thereby realizing the left and right twisting of the steering wheel 14. When the dump bucket 2 is pushed forward and backward, the steering column 32 of the handlebar 3 will move forward and backward together, which will drive the first U-shaped axle fork 41 to rotate forward and backward, and then the first articulated shaft 43 will drive the second articulated shaft 44 to rotate forward and backward. At this time, the second U-shaped axle fork 42 will not move accordingly, thus realizing the forward and backward rotation of the dump bucket 2. The first U-shaped axle fork 41 and the second U-shaped axle fork 42 are both composed of a bottom plate and two articulated ear plates, the two articulated ear plates are located on both sides of the bottom plate, and the two ends of the shaft body of the first articulated shaft 43 and the second articulated shaft 44 are respectively rotatably connected in the ear plate holes of the two articulated ear plates through bearings. The steering column 32 is fixedly connected to the side of the bottom plate of the first U-shaped axle fork 41 that is away from the first articulated shaft 43. The steering wheel 14 includes a mounting frame and a wheel body rotatably connected to the mounting frame, and a driving shaft is fixedly connected to the mounting frame, and the driving shaft is fixedly connected to the side of the bottom plate of the second U-shaped axle fork 42 that is away from the second articulated shaft 44.
