[0026] As shown in the accompanying Figure 1 to the accompanying Figure 4 :

[0027] The utility model provides a kind of power-assisted tool car, including chassis 1, positive and negative bicycle head 2, steering column 3, steering handle 4 and steering wheel group 5, the head chassis 26 of chassis 1 and positive and negative bicycle head 2 are mutually fixed and installed together, the lower end of the steering column 3 rotationally installed on head chassis 26 is mutually installed with steering wheel group 5, and the upper end of steering column 3 is provided with steering handle 4;Positive and negative bicycle head 2 includes bearing sleeve 21, connecting rod 22, seat plate 23, support rod 24 and sleeve seat 25, bearing sleeve 21 is rotationally installed on steering column 3, and bearing sleeve 21 is installed together with seat plate 23 by connecting rod 22, and support rod 24 fixedly installed on seat plate 23 is clamped in the inboard of sleeve seat 25 fixedly installed on head chassis 26.

[0028] Further, power driver 6 is installed below chassis 1, which significantly improves the driving force of the vehicle.The output end of power driver 6 is fixed with two power moving wheels 7, which are ingeniously located on the outer side of chassis 1.This layout not only enhances the stability of the vehicle, but also enables the vehicle to better cope with various complex road conditions during driving.

[0029] Further, a rectangular tool box 8 is fixedly installed above chassis 1.This tool box 8 provides sufficient storage space for the rider, making it convenient to store various tools and items.In order to maintain the cleanliness and safety of tool box 8, a cover plate 9 is hingedly installed on top, which can be easily opened or closed by the rider to access the items inside tool box 8.

[0030] Further, the space layout between tool box 8 and steering column 3 is carefully designed to ensure that seat plate 23 and support rod 24 can move freely in this area.This design avoids the interference of tool box 8 with the movement of seat plate 23 and support rod 24, allowing the rider to flexibly adjust the position of seat plate 23 as needed.

[0031] Further, a handle 27 is provided on the outer surface of seat plate 23, which greatly improves the riding experience of the rider.Handle 27 is located between the upper ends of the two support rods 24, and the rider can easily grasp handle 27 to maintain balance and stability of the body, and conveniently adjust seat plate 23.

[0032] Further, seat plate 23 is connected to bearing sleeve 21 through connecting rod 22, which allows seat plate 23 to move in an arc trajectory outside bearing sleeve 21.At the same time, bearing sleeve 21 can move in a circular trajectory around steering column 3.This composite motion trajectory design allows the rider to switch between "positive three-wheel" and "riding a donkey backwards", thereby adapting to different driving environments and individual needs.

[0033] Further, the sleeve seat 25 is an important component fixedly installed on the head chassis 26, which is arranged in a manner of two for a group. The two sleeve seats 25 of each group have a certain spacing, which not only ensures the stability of the seat plate 23 and the support rod 24, but also avoids interference therebetween. Meanwhile, the sleeve seat 25 is fixedly installed in an inclined manner, and the cross section thereof is in a "N" shape structure, which enables the sleeve seat 25 to better fix and support the seat plate 23 and the support rod 24.

[0034] Further, the steering handle 4 adopts an "X" type structure, which is not only beautiful and elegant, but also enhances the controllability of the rider. The intermediate region of the steering handle 4 extends to a certain extent outwardly to form branch ends. The extension directions of the branch ends are perpendicular to the extension direction of the intermediate region, thereby forming branch grip regions. Such a design enables the rider to be more flexible and stable when controlling the vehicle, thereby improving the safety of driving.

[0035] The working principle is as follows: firstly, the power-assisted tool vehicle provided by the utility model is characterized in that the core lies in the design of the reverse riding head 2, which enables the rider to flexibly switch between the "forward three-wheel" and "reverse riding" riding modes. In the initial state, the seat plate 23 is connected to the bearing sleeve 21 through the connecting rod 22, and is limited by the sleeve seat 25 on the support rod 24 and the head chassis 26, thereby maintaining a relatively stable position.

[0036] When the rider wants to switch from the "forward three-wheel" riding mode to the "reverse riding" riding mode, or wants to switch from the "reverse riding" riding mode to the "forward three-wheel" riding mode, firstly, the rider will hold the handle 27 outside the seat plate 23, and then move the seat plate 23 upward, so that the seat plate 23 moves in an arc trajectory outside the bearing sleeve 21 through the connecting rod 22, and the support rod 24 of the seat plate 23 is released from the limitation of the sleeve seat 25 on the head chassis 26. Then, the seat plate 23 is rotated, and the seat plate 23 rotates around the axis of the bearing sleeve 21.

[0037] With the rotation of the seat plate 23, the support rod 24 also moves, and reaches a new position adapted to the seat plate 23. Then, the seat plate 23 is moved downward, and the support rod 24 of the seat plate 23 is limited by the new sleeve seat 25, thereby realizing the switching between the "forward three-wheel" and "reverse riding" riding directions.

[0038] Any similar technical scheme that achieves the above technical effects falls within the protection scope of the utility model.
