[0013] Beneficial effects: 1. This utility model facilitates the loading and unloading of heavy objects through the installation of side plates, traction ropes, and a winding reel. The motor drives the winding reel to rotate, which in turn winds the traction rope. The hook pulls the object, facilitating its movement and allowing it to slide onto the side plate. The rotating wheels further facilitate this sliding. Adjusting the position of the support wheels allows their tops to move out of the groove. Once the object is on the trolley body, the support wheels provide support. The drive mechanism continues to move the object to a predetermined position, causing the support wheels to return to their original position and no longer support the object. This allows the bottom of the object to fit against the bottom of the trolley body, thus limiting its position and enabling rapid handling of heavy objects, improving work efficiency. After the object is moved to the predetermined position, the electric push rod moves the support wheels, lifting the object. Manual pushing of the object, aided by the support wheels, facilitates its sliding, making unloading easier and enhancing the practicality of the electric trolley.

[0017] 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.

[0018] Please see Figure 1-5 As shown, an electric trolley includes a trolley body 1, a handle 3 on the trolley body 1, and symmetrically mounted wheels 2 at the bottom of the trolley body 1. A frame 14 is symmetrically arranged inside the trolley body 1, with grooves 15 arranged in an array on the frame 14. Support wheels 16 are rotatably mounted inside the grooves 15. A support plate 18 is arranged inside the frame 14, and a bracket 17 corresponding to the support wheel 16 is fixedly mounted on the support plate 18, with the bracket 17 rotatably connected to the end of the support wheel 16. The frame 14 also has a fixed... An electric push rod 19 is provided, and the telescopic end of the electric push rod 19 is fixedly connected to the support plate 18. A support block 24 is fixedly provided on the side of the trolley body 1. A support shaft 25 is passed through the support block 24. A side plate 21 is provided on the side of the trolley body 1. A through hole 26 corresponding to the support shaft 25 is provided on the side plate 21, and the support shaft 25 passes through the through hole 26. An array of mounting grooves 22 is provided inside the side plate 21. A rotating wheel 23 is rotatably provided inside the mounting groove 22. A drive mechanism is provided on the top of the trolley body 1. A battery is installed below the trolley body 1, and the battery is electrically connected to the electronic equipment on the trolley body 1 for power supply. When using the electric trolley to transport items, after placing the items on the trolley body 1, pushing the handle 3, and cooperating with the walking wheels 2, allows the trolley body 1 to move, thereby transporting the objects. When transporting large objects, a foot brake (existing technology) is installed on the walking wheels 2 to fix the position of the walking wheels 2. The side plate 21 is moved so that the through hole 26 on the side plate 21 is aligned with the hole on the support block 24. After the support shaft 25 is moved through the through hole 26 and the support block 24, it can support one side of the side plate 21, and the other side of the side plate 21 contacts the ground, so that the traction rope 12 and the hook 13 are connected to the side of the object. The drive mechanism is controlled to move the traction rope 12 to rewind, thereby pulling the object to move, making the object slide onto the side plate 21. The rotating wheel 23 facilitates the movement of the object. The object slides smoothly, allowing personnel to assist in its movement and prevent accidental drops. Simultaneously, the electric push rod 19, in conjunction with the support plate 18 and bracket 17, adjusts the position of the support wheel 16. After the top of the support wheel 16 moves out of the groove 15, the object is supported by the support wheel 16 once it reaches the trolley body 1. The drive mechanism continues to move the object to a predetermined position. Then, the electric push rod 19 is activated, causing the support wheel 16 to reset and no longer support the object, allowing the bottom of the object to fit against the bottom of the trolley body 1. This limits the object's position, enabling rapid handling of heavier objects and improving work efficiency. After moving the object to the predetermined position, the electric push rod 19 is activated to move the support wheel 16, lifting the object. Manual pushing of the object, aided by the support wheel 16, facilitates its sliding and unloading.

[0019] Furthermore, the drive mechanism includes a frame 5, a power motor 6, a transmission rod 7, a reducer 8, a drive rod 9, and a winding assembly. The frame 5 is fixedly installed on the top of the trolley body 1, the power motor 6 is fixedly installed inside the frame 5, one end of the transmission rod 7 is fixedly connected to the output end of the power motor 6, the reducer 8 is fixedly installed inside the frame 5, and one end of the transmission rod 7 is connected to the input end of the reducer 8, the drive rod 9 is rotatably installed inside the frame 5, and one end of the drive rod 9 is fixedly connected to the output end of the reducer 8, and the winding assembly is installed on the drive rod 9. The operation of the control motor 6 will drive the transmission rod 7 to rotate. When the transmission rod 7 rotates, it will cause the reducer 8 to move. The movement of the reducer 8 increases the torque, causing the drive rod 9 to rotate. The drive rod 9 causes the winding assembly to move. Through the cooperation of the traction rope 12 and the hook 13, the object can be pulled to move.

[0020] Furthermore, the winding assembly includes a winding reel 10, a limiting tube 11, a traction rope 12, and a hook 13. The winding reels 10 are arrayed and mounted on the drive rod 9. The limiting tube 11 corresponding to the winding reel 10 is embedded inside the frame 5. The traction rope 12 passes through the limiting tube 11, and one end of the traction rope 12 is fixedly connected to the winding reel 10. The traction rope 12 is wrapped around the winding reel 10. The hook 13 is fixedly connected to the other end of the traction rope 12. When moving a heavy object, pull the hook 13 and the traction rope 12 to connect the hook 13 to the side of the object. Then, rotate the drive rod 9. When the drive rod 9 rotates, it will drive the winding reel 10 to rotate. When the winding reel 10 rotates, it will wind up the traction rope 12, and then pull the object through the hook 13 to move it, thus facilitating the movement of the object.

[0021] Furthermore, a controller 4 is fixedly installed on the handrail 3, and the power motor 6 and the electric push rod 19 are both electrically connected to the controller 4; The electronic equipment on the electric cart can be controlled via controller 4.

[0022] Furthermore, a storage slot 20 is fixedly provided at the bottom of the trolley body 1, and the storage slot 20 is used to store the side panel 21. By disassembling the side panel 21, the side panel 21 can be moved into the storage slot 20, and then the side panel 21 can be stored.

[0023] Furthermore, a drive gear 27 is fixedly installed on the transmission rod 7, and a fan 29 is fixedly installed inside the frame 5. The impeller inside the fan 29 is fixedly connected to a driven gear 28 through a shaft, and the drive gear 27 meshes with the driven gear 28. When the transmission rod 7 rotates, it will drive the drive gear 27 to rotate. The drive gear 27 and the driven gear 28 cooperate to make the fan 29 work and generate wind.

[0024] Furthermore, the front of the frame 5 is arrayed with air jet holes 30, and the output end of the fan 29 is connected to the input end of the air jet hole 30 through a pipe; the air generated by the fan 29 will flow into the air jet hole 30, and the air jet hole 30 will cause the air to flow to the trolley body 1, which can clean the surface of the trolley body 1 and ensure the cleanliness of the surface of the trolley body 1.

[0025] As a technical optimization of this utility model, after placing an item on the trolley body 1, pushing the handle 3, in conjunction with the traveling wheels 2, allows the trolley body 1 to move, thus enabling the transport of objects. When transporting large objects, the position of the traveling wheels 2 is fixed, and the side plate 21 is moved so that the through hole 26 on the side plate 21 is aligned with the hole on the support block 24. After moving the support shaft 25 through the through hole 26 and the support block 24, one side of the side plate 21 is supported, while the other side of the side plate 21 contacts the ground, allowing the traction rope 12 and hook 13 to contact the object side. When the surface is connected, the control motor 6 drives the transmission rod 7 to rotate. The rotation of the transmission rod 7 causes the reducer 8 to move, increasing the torque and causing the drive rod 9 to rotate. The rotation of the drive rod 9 drives the take-up reel 10 to rotate, which in turn winds the traction rope 12, pulling the object through the hook 13. This facilitates the movement of the object, allowing it to slide onto the side plate 21. The rotating wheel 23 further facilitates this sliding, allowing personnel to assist in sliding the object and prevent accidental drops. Simultaneously, the electric push rod 19 operates via the support... The plate 18 and the bracket 17 work together to adjust the position of the support wheel 16. After the top of the support wheel 16 moves out of the groove 15, when the object moves onto the trolley body 1, the support wheel 16 supports the object. The drive mechanism continues to move, pulling the object to the predetermined position. Then, the electric push rod 19 is controlled to work, causing the support wheel 16 to reset and no longer support the object. This allows the bottom of the object to fit against the bottom of the trolley body 1, thus limiting the position of the object. This achieves the purpose of quickly transporting heavier objects, improving work efficiency and moving the object to the predetermined position. Then, the electric push rod 19 is controlled to move the support wheel 16, which can lift the object and push it manually. With the support wheel 16, the object can slide, which facilitates the unloading of the object. When the transmission rod 7 rotates, it will drive the drive gear 27 to rotate. The drive gear 27 and the driven gear 28 cooperate to make the fan 29 work to generate wind. The wind generated by the fan 29 will flow into the air jet hole 30. Through the air jet hole 30, the wind will flow to the trolley body 1, which can clean the surface of the trolley body 1 and ensure the cleanliness of the surface of the trolley body 1.
