[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] like Figure 1-5 As shown, an embodiment of this utility model discloses an electric handcart, including a base component 1 and reinforcing base rods 2 fixed on the left and right sides of the base component 1. The base component 1 serves as the basic load-bearing component of the handcart, providing mounting support for other components, while the reinforcing base rods 2 are used to mount components such as push wheels 3 and guide rods 6, and also include:

[0031] The push wheel 3 is rotatably connected to the inner side of the reinforcing base rod 2. The push wheel 3 provides the main power support for the movement of the handcart. Its rotatable connection can be achieved using bearings to ensure smooth rotation. Reinforcing rods 4 are symmetrically fixed on the left and right sides of the lower end face of the base component 1. Universal wheels 5 are fixed to the lower end face of the reinforcing rods 4, allowing for flexible rotation and facilitating changes in the handcart's direction of travel, thus improving the handcart's maneuverability. The guide rod 6 is fixed to the other end of the reinforcing base rod 2 and is arranged in a figure-eight shape. Through the set… The figure-eight structure is ergonomic, making it easy for operators to grip and push the trolley, improving operational comfort and convenience. The control panel 7 is fixed between two sets of guide rods 6, and the handle 8 is fixed to the end of one set of guide rods 6, with an electrical connection between the handle 8 and the control panel 7. The control panel 7 is used to control the operating status of the electric trolley, such as starting, stopping, and speed adjustment. The handle 8 facilitates operator control of the trolley, and control signals can be sent to the control panel 7 through the handle 8 to achieve convenient control of the trolley.

[0032] A connecting rod 9 is fixed to the left and right sides of the reinforcing base rod 2. A bearing frame 10 is rotatably connected to the outer side of the connecting rod 9, and a hopper component 16 is fixed to the upper end face of the bearing frame 10. The cross-section of the bearing frame 10 is stepped and is rotatably connected to the reinforcing base rod 2 via the connecting rod 9. The stepped structure can better adapt to the shape of the hopper component 16, increase the stability of the hopper component 16, and prevent materials from falling during transportation. A locking mechanism is set on the upper end face of the base component 1 to lock and limit the position of the bearing frame 10.

[0033] The locking mechanism includes a locking chamber 12, a locking rod 13, a connecting sleeve 14, and a return spring 15. The locking chamber 12 is fixed to the upper end face of the base component 1. The locking rod 13 is fixed to one side of the inner wall of the locking chamber 12. The connecting sleeve 14 is sleeved on the outer surface of the locking rod 13. The return spring 15 is sleeved on the outer surface of the locking rod 13, and the other end of the return spring 15 is connected to the connecting sleeve 14. A locking plate 11 is fixed to the lower end face of the support frame 10, and the other end of the locking plate 11 is slidably embedded in the locking chamber 12. The other end of the connecting sleeve 14 is slidably engaged inside the locking plate 11. When it is necessary to fix the support frame 10, the support frame 10 is rotated to a suitable position, and the lock at the lower end of the support frame 10... The clamping plate 11 slides into the locking chamber 12. At this time, the return spring 15 is in a natural or slightly compressed state. The connecting sleeve 14 slides along the locking rod 13 under the action of the return spring 15, so that the other end of the connecting sleeve 14 slides and engages inside the locking plate 11, thereby locking and limiting the position of the support frame 10. When it is necessary to adjust the position of the support frame 10, the operator can apply external force to push the connecting sleeve 14, compress the return spring 15, and make the connecting sleeve 14 disengage from the locking plate 11. At this time, the support frame 10 can be rotated to the desired position, the connecting sleeve 14 is released, and the connecting sleeve 14 is engaged again in the locking plate 11 under the action of the return spring 15, completing the locking after position adjustment.

[0034] A lithium battery assembly is fixed at the center of the lower end face of the base component 1; the lithium battery assembly provides power for the drive of the push wheel 3 and electrical components such as the control panel 7. The lithium battery assembly has the advantages of large capacity, light weight, convenient charging and long cycle life, which can ensure the stable operation of the handcart for a long time and make it easy for operators to replenish the power of the handcart in a timely manner, thus improving the convenience and endurance of the handcart.

[0035] In use, the lithium battery pack powers the entire electrical system of the handcart. The operator holds the handle 8 and starts the handcart via the control panel 7, which drives the wheels 3 to rotate under electric power, propelling the handcart forward. The casters 5 assist in changing direction.

[0036] Then, the material is placed into the hopper 16. The position of the support frame 10 can be adjusted according to the material placement requirements. During adjustment, the connecting sleeve 14 is pushed to compress the return spring 15, so that the connecting sleeve 14 is disengaged from the locking plate 11. After rotating the support frame 10 to the appropriate position, the connecting sleeve 14 is released. Under the action of the return spring 15, the connecting sleeve 14 is locked in the locking plate 11, thus completing the fixation of the support frame 10.

[0037] During transport, the locking mechanism ensures the stability of the support frame 10, preventing materials from easily falling off. Upon arrival at the destination, the trolley is stopped via the control panel 7. If materials need to be unloaded, the position of the support frame 10 can be readjusted for easy removal. When the lithium battery pack is low on power, it can be removed for charging or directly connected to a charger to ensure the trolley's continued normal operation.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
