The loading platform 2 is also provided with an unlocking button 4 that engages with the end of the handrail 1. The handrail 1 includes a support rod 5, a telescopic rod 6 that is slidably connected in the support rod 5, a fixed rod 7 that is vertically installed on the top of the support rod 5, a crossbar 8 installed on the telescopic rod 6, and a button switch 9 located in the middle of the upper end of the fixed rod 7. The two ends of the fixed rod 7 are engaged with the telescopic rod 6. The telescopic rod 6 is unlocked or locked by the button switch 9. The end of the support rod 5 is also provided with a folding mechanism 10 that is rotatably connected to the loading platform 2.

[0021] The folding mechanism 10 includes a mounting base 11 connected to the loading platform 2. A deep groove 12 with the same cross-section as the support rod 5 is opened in the mounting base 11. Support plates 13 are installed opposite each other on both sides of the deep groove 12. Guide wheels 14 are installed on the inner side of the support plates 13. Slide grooves 15 are also opened on both sides of the end of the support rod 5. The guide wheels 14 are in rolling connection with the slide grooves 15, so that the support rod 5 can move up and down along the folding mechanism 10, and at the same time rotate and fold towards the loading platform 2 with the guide wheels 14 as the rotation center. The end of the support rod 5 is engaged with the mounting base 11. The engagement can be released by the unlocking button 4 so that the support rod 5 can slide upward and get away from the mounting base 11. During the sliding process, the guide wheels 14 are always in the slide grooves 15 to guide the sliding direction. After that, the end of the support rod 5 is limited by the guide wheels 14 and can only rotate and move to both sides, that is, rotate closer to or away from the loading platform 2, so that the handrail 1 can be stored on the top of the loading platform 2 for easy carrying and movement. When unfolded, the armrest 1 rotates to a vertical position with the guide wheel 14 as the center of rotation, and then moves downward to insert into the deep groove 12 of the mounting base 11 to fix it, and is locked by the structure at the unlock button 4.

[0022] The rear end of the cargo platform 2 is also equipped with a battery pack 16, a hub motor 17 connected to the rollers 3, a controller located within the cargo platform 2, and a control switch mounted on the handrail 1. The control switch consists of a speed switch 18 and a direction switch 19, which are electrically connected to the controller via wires. The cargo platform 2 also has a quick-release interface for installing the battery pack 16. The hub motor 17 connects to the rollers 3 to control their rotation. The battery pack 16 is electrically connected to the internal controller via the quick-release interface. Simultaneously, the wires connect to the inside of the handrail 1 via a folding mechanism 10, and finally connect to the control switch, allowing the controller to drive the battery pack 16, hub motor 17, and control switch. The quick-release interface allows for easy and quick replacement of the battery pack 16 for power supply during use.

[0023] The upper inner side of the telescopic rod 6 is provided with a slot 20, and both ends of the fixed rod 7 are provided with locking blocks 21 connected to the push-button switch 9. Pressing the push-button switch 9 causes the locking blocks 21 to retract or reset, and the locking blocks 21 connect with the slot 20 to fix the telescopic rod 6 and the fixed rod 7. The upper sides of the opposite surfaces of the telescopic rods 6 on the left and right sides are provided with slots 20. The fixed rod 7 is equipped with an elastic element and a moving element. When the push-button switch 9 is pressed, it drives the moving element to move downward, thereby causing the elastic element and the locking blocks 21 to extend and retract inward until they are completely disengaged from the slot 20, so that the telescopic rod 6 can slide freely up and down along the support rod 5. Similarly, after the push-button switch 9 is released, the elastic element resets and the locking blocks 21 extend, rubbing and pressing against the outer contour of the telescopic rod 6 until they are located in the slot 20, fixing the telescopic rod 6 and locking it up and down.

[0024] The loading platform 2 is also equipped with multiple sliding grooves 22 and locking buttons 23 for securing items. The locking buttons 23 can be used to block or reset the openings of the sliding grooves 22. Items with snap-fit ​​feet, such as the bottom of a toolbox, can be snapped onto the loading platform 2 via the sliding grooves 22. The toolbox is then fixed in place by the elastic latches within the sliding grooves 22. Pressing the locking button 23 causes the elastic latches to retract, releasing the snap-fit ​​feet and unlocking the toolbox. Locking prevents the toolbox from sliding and tipping over during transport, enhancing safety.

[0025] The rear end of the cargo platform 2 is also provided with a recessed foot pedal area 24, and a set of grooves 25 are provided on the foot pedal area 24 to increase friction. The foot pedal area 24 is used to position the foot when going uphill to prevent it from tipping over backward. When the foot is stepped on, the grooves 25 can provide greater friction, making the cargo platform 2 more stable.

[0026] The lower inner side of the support rod 5 is also provided with a slot 20. A locking block 21 connected to the unlock button is provided on the inner side of the deep groove 12. By pressing the unlock button 4, the locking block 21 is retracted or reset. The connection between the locking block 21 and the slot 20 fixes the support rod 5 to the deep groove 12 in the mounting base 11. Similar to the structure of the button switch 9, when pressed, the driving moving part moves downward, thereby causing the elastic element and the locking block 21 to extend and retract inward until they are completely disengaged from the slot 20, allowing the support rod 5 to be released and slide freely up and down along the mounting base 11. After releasing the unlock button, the elastic element resets, causing the locking block 21 to extend and rub against the outer contour of the support rod 5 until it is located in the slot 20, fixing the support rod 5 and locking it up and down.

[0027] In practical use: The cargo platform 2 uses a lithium battery and a controller to control two hub motors 17 to drive the rollers 3 as drive wheels. The electric power platform is turned on and off by the controller switch. The speed switch 18 is used to control the driving speed of the hub motors 17, and the direction switch 19 is used to control the forward and backward movement of the hub motors 17.

[0028] The electric power-assisted platform has rotation and retraction functions. When not in use, the first step is to press the button switch 9 to retract the telescopic rod 6 into the support rod 5. The second step is to step on the unlock button 4, hold the support rod 5 with both hands and lift it up to remove it from the limit of the loading platform 2, rotate it in the direction of the loading platform 2, and let the handrail 1 lie flat on the loading platform 2.

[0029] When using the electric power-assisted platform, the first step is to rotate the handle 1 so that it is perpendicular to the load platform, and press the handle 1 down so that the end of the support rod 5 is locked back to the load platform through the unlock button. The second step is to press the button switch 9 to lift the telescopic rod 6, which will switch the electric power-assisted platform to the usable state.

[0030] This invention powers the hub motor and controller with a lithium battery. The control switch controls the wheels to move forward or backward and the speed can be controlled without manual pushing or pulling, saving labor. Furthermore, the device uses a folding mechanism to store the armrest on the loading platform, allowing it to lie flat on top of the platform, saving space and making it easy to carry and move. The battery uses a quick-release interface connection, which can be carried and replaced at any time when the power is low, extending the usage time.
