[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a portable wheeled vehicle with a solar energy automatic tracking function, including a frame 1, a folding bin 2, a solar energy automatic tracking mechanism, a solar panel folding and unfolding mechanism and a folding and storing mechanism. The folding bin 2 is fixedly provided in the frame 1. The solar energy automatic tracking mechanism includes a bottom plate 3, an electric telescopic rod 4, a rotating frame 5, a column 6 and a photoelectric sensor 7. The bottom plate 3 is fixedly provided in the middle of the frame 1. The electric telescopic rod 4 is fixedly provided in the middle of the bottom plate 3 through the folding bin 2. The rotating frame 5 is fixedly provided at the telescopic end of the electric telescopic rod 4. A column 6 is rotatably provided above the rotating frame 5. The photoelectric sensor 7 is fixedly provided at the upper end of the column 6 The rotating frame 5 is electrically driven by a motor, and the photoelectric sensor 7 is electrically connected to the motor. There are multiple groups of photoelectric sensors 7. When it is necessary to receive solar energy, the electric telescopic rod 4 is extended to increase the height. The photoelectric sensor 7 detects the intensity of sunlight in different directions. When the intensity of light is strongest in a certain direction, the approximate direction of the sun can be determined, and the direction of the rotating frame 5 can be adjusted so that the fan-shaped solar panel 9 is always facing the sun after being unfolded, so as to improve the energy collection efficiency, realize real-time tracking according to the direction of the sun, and maximize the solar energy collection efficiency. A solar energy collection and expansion mechanism is provided on the column 6, and a folding and storage mechanism is provided between the frames 1.

[0022] The solar panel folding and unfolding mechanism includes a rotating sleeve 8, a fan-shaped solar panel 9 and a magnetic limit block 10. The rotating sleeve 8 is arranged on the column 6, and the rotating sleeve 8 is stacked in multiple groups. A fan-shaped solar panel 9 is fixedly provided on the other side of the rotating sleeve 8. A magnetic limit block 10 is fixedly provided on the end of the fan-shaped solar panel 9. The fan-shaped solar panels 9 are electrically connected. The magnetic limit block 10 is in contact and adsorbed with the previous group of fan-shaped solar panels 9. When it is necessary to absorb solar energy, the fan-shaped solar panel 9 is moved to rotate and unfold in turn, and the magnetic limit block 10 is adsorbed with the frame of the previous group of fan-shaped solar panels 9 to form a circular solar panel matrix. When it is necessary to store, the fan-shaped solar panel 9 is moved to fold and then the rotating frame 5 is rotated to store the fan-shaped solar panel 9 in the folding bin 2, which effectively prevents the solar panel from being damaged during storage and use.

[0023] A storage compartment 11 is fixedly provided at the front of one side of the frame 1, and a power bank 12 is placed in the storage compartment 11. A controller 13 is fixedly provided on one side of the frame 1, and the controller 13 is electrically connected to the electric telescopic rod 4. The power bank 12 is electrically connected to the fan-shaped solar panel 9 and the controller 13 for charging and power supply, so that the electric energy absorbed and converted by the fan-shaped solar panel 9 can be charged into the power bank 12, and at the same time, the power bank 12 provides power for the electric telescopic rod 4 to extend and move.

[0024] The folding and storing mechanism includes an articulated support frame 14, an articulated folding frame 15, a sliding rod 16 and a lifting sleeve 17. An articulated support frame 14 is connected between the frame 1 and the bottom plate 3. An articulated folding frame 15 is symmetrically connected between the frames 1. Sliding rods 16 are symmetrically fixed at the front and rear corners of the frame 1. A lifting sleeve 17 is fixed above the articulated folding frame 15. The sliding rod 16 passes through the lifting sleeve 17 for sliding cooperation. When folding is required, the frame 1 is squeezed and pushed toward each other to make the articulated support frame and the articulated folding frame 15 rotate and contract to store and fold the folding bin 2, which is convenient for reducing the size and making it easy to place the car in the trunk of the vehicle and carry it to different locations.

[0025] The four corners of the frame 1 are fixed with connecting frames 18 by bolts, the lower end of the connecting frame 18 is fixed with a spring 19, and a universal wheel 20 is fixed below the spring 19. When the trolley moves, the universal wheel 20 rotates to drive the frame 1 to move, and the spring 19 effectively eliminates vibration during the movement.

[0026] A fixing frame 21 is fixedly provided in the middle of one side of the frame 1, a hinge seat 22 is fixedly provided on the fixing frame 21, and a handle 23 is hingedly connected on the hinge seat 22. When moving, the handle 23 is pulled to drive the frame 1 to move under the rotation of the universal wheel 20.

[0027] When the portable wheeled trolley with the solar energy automatic tracking function is used, it is taken down from the trunk of the vehicle and then the frame is pulled out so that the articulated support frame and the articulated folding frame are articulated, rotated and unfolded, and the folding bin is driven to unfold for convenient placement of items. When it is necessary to use solar energy for power generation, the power bank is placed in the placement bin and connected with the controller and the fan-shaped solar panel wiring. The fan-shaped solar panel is moved to rotate and unfold along the column, and the magnetic limit block is adsorbed and limited by another group of fan-shaped solar panel frames. Then, the controller controls the electric telescopic rod to extend and drive the fan-shaped solar panel to rise. The photoelectric sensor drives the motor to rotate and adjust the angle of the rotating frame according to the intensity of sunlight to ensure the maximum solar energy collection efficiency. When it is necessary to move, the handle is pulled to rotate the universal wheel to drive the frame to move horizontally. During the movement, the spring elastic compression resolves the bumps. When it is necessary to fold and store, the fan-shaped solar panel is rotated and folded, and then the rotating frame is rotated to rotate the fan-shaped solar panel to fit the electric telescopic rod to reduce the occupied volume. The frame is pushed to move toward each other so that the articulated support frame and the articulated folding frame are retracted to drive the folding bin to fold and shrink for convenient storage and transportation.
