[0043] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] Embodiment 1:

[0045] Please refer to Figure 2-Figure 3A solar charging device for a vehicle that is convenient to carry with the vehicle comprises a roof rack 1 arranged on the roof of the vehicle, and also comprises a driving protection structure 2 arranged on the upper end of the roof rack 1, a photovoltaic power generation mechanism 3 is arranged inside the driving protection structure 2, and a photovoltaic panel retracting mechanism 4 is arranged inside the photovoltaic power generation mechanism 3;

[0046] The driving protection structure 2 includes a bottom protection frame 5 fixedly arranged on the top surface of the roof rack 1 , a top protection frame 6 is arranged at the upper end of the bottom protection frame 5 , and avoidance grooves 7 are provided on the surfaces of the bottom protection frame 5 and the top protection frame 6 .

[0047] Specifically, arc-shaped guide frames 8 are fixedly connected to both sides of the bottom protective frame 5, and an arc-shaped guide groove 9 is opened through the surface of the arc-shaped guide frame 8. A servo motor 10 is fixedly connected to the surface of the arc-shaped guide frame 8, and the output end of the servo motor 10 is transmission-connected to a transmission shaft 11, and the transmission shaft 11 is rotationally connected to the bottom protective frame 5. The top protective frame 6 is fixedly connected to the surface of the transmission shaft 11, and the rear end of the top protective frame 6 is symmetrically fixedly connected to a guide rod 12, and the guide rod 12 is slidably connected to the inner wall of the arc-shaped guide groove 9.

[0048] Specifically, the bottom protective frame 5 is fixedly connected to the inside with a main support frame 13, the side of the main support frame 13 away from the bottom protective frame 5 is fixedly connected to a first photovoltaic panel 14, the inner wall of the top protective frame 6 is fixedly connected to a secondary support frame 15, and the side of the secondary support frame 15 away from the top protective frame 6 is fixedly connected to a second photovoltaic panel 16.

[0049] Through the above structural design, when the vehicle is driving, the bottom protection frame 5 and the top protection frame 6 are in a closed state, which can reduce the driving wind resistance;

[0050] When the device is in use, the vehicle is stationary. After completion, the servo motor 10 is turned on. The servo motor 10 drives the transmission shaft 11 to rotate. While the transmission shaft 11 rotates, it drives the guide rod 12 to slide on the inner wall of the arc guide groove 9 until the top protective frame 6 flips 180 degrees, the top protective frame 6 and the bottom protective frame 5 are in a parallel state, and the second photovoltaic panel 16 and the surface of the first photovoltaic panel 14 are in a parallel state.

Through the conversion of the inverter, the electrical energy can be transmitted to the vehicle-mounted battery for storage and use.

[0051] Embodiment 2:

[0053] Specifically, a first guide seat 24 is symmetrically fixedly connected to one end of the main support frame 13 away from the first guide rail 20, and a first slide rod 25 is slidingly connected to the middle parts of the two first guide seats 24 respectively. The top surfaces of the two first slide rods 25 are respectively fixedly connected to the third photovoltaic panel 26, and one end of the third photovoltaic panel 26 away from the first slide rod 25 is respectively fixedly connected to the top surface of the first connecting seat 23.

[0054] Specifically, a dual-axis synchronous motor 28 is fixedly connected inside the bottom protection frame 5, and threaded rods 29 are respectively connected at both ends of the dual-axis synchronous motor 28 by transmission. The bottom surfaces of the two third photovoltaic panels 26 are respectively fixedly connected with transmission blocks 27, and the two transmission blocks 27 are respectively threadedly connected to the threaded rods 29 at the output ends of both sides of the dual-axis synchronous motor 28.

[0055] Specifically, the second guide rail 42 is fixedly connected to the inside of one end of the auxiliary support frame 15 away from the bottom protection frame 5, the inner wall of the second guide rail 42 is symmetrically rotationally connected to the second directional pulley 33, the middle parts of the two groups of second directional pulleys 33 are respectively rotationally connected to the second rotating rod 34, and the second rotating rod 34 is fixedly connected to the second connecting seat 35 at one end away from the second directional pulley 33.

[0056] Specifically, the secondary support frame 15 is symmetrically fixedly connected to the inside of one end near the bottom protective frame 5, the inner walls of the two second guide seats 31 are respectively slidably connected to the second slide bars 32, the top surfaces of the two second slide bars 32 are respectively fixedly connected to the fourth photovoltaic panels 36, and the ends of the two fourth photovoltaic panels 36 away from the second slide bars 32 are respectively fixedly connected to the two second connecting seats 35.

[0057] Specifically, the side of the second directional pulley 33 away from the first guide rail 20 is fixedly connected to the first linkage rod 30, the end of the first linkage rod 30 away from the second slide rod 32 is fixedly connected to the fixed connection seat 38, and the surface of the fixed connection seat 38 is longitudinally provided with a plug-in groove 39, the side of the second connection seat 35 away from the second guide rail 42 is fixedly connected to the second linkage rod 37, the end of the second linkage rod 37 away from the second guide rail 42 is fixedly connected to the movable connection seat 40, and the surface of the movable connection seat 40 is fixedly connected to the plug-in block 41, and the plug-in block 41 is plugged into the inner wall of the plug-in groove 39.

[0058] Through the above structural design, when the transmission shaft 11 drives the top protection frame 6 to flip, the second linkage rod 37 drives the movable connection seat 40 to flip together, and when the movable connection seat 40 flips, it drives the plug-in block 41 to be plugged into the middle of the plug-in slot 39;

[0059] After completion, the dual-axis synchronous motor 28 is turned on, and the dual-axis synchronous motor 28 drives the threaded rod 29 to rotate. Since the threaded rod 29 is threadedly connected to the transmission block 27, the threaded rod 29 rotates and drives the transmission block 27 to move. The transmission block 27 drives the third photovoltaic panel 26 to slide to both sides. At the same time, the third photovoltaic panel 26 drives the first connecting seat 23 to make the first directional pulley 21 slide on the inner wall of the first guide rail 20, and the first sliding rod 25 slides on the inner wall of the first guide seat 24. In this way, the two third photovoltaic panels 26 can be moved from the middle of the main support frame 13 to the outside and unfolded.

[0060] When the first connecting seat 23 moves, it drives the first linkage rod 30 and the fixed connecting seat 38 to move. Since the movable connecting seat 40 is clamped to the middle of the plug-in slot 39 through the plug-in block 41, the first linkage rod 30 can drive the second linkage rod 37 to move synchronously when it moves. The second linkage rod 37 drives the second connecting seat 35 to make the second directional pulley 33 slide to both sides on the inner wall of the second guide rail 42. In this way, the fourth photovoltaic panel 36 can be unfolded to further increase the area of ​​the photovoltaic panel, thereby improving the overall power generation efficiency of the device.

[0061] Embodiment 3:

[0063] Through the above-mentioned structural design, since cleaning rollers 19 are arranged on both sides of the main supporting frame 13, when the third photovoltaic panel 26 moves to both sides or contracts inward, the cleaning rollers 19 are in close contact with the surface of the third photovoltaic panel 26, and the cleaning rollers 19 can be driven to rotate by friction. While the cleaning rollers 19 rotate, the floating dust and debris on the surface of the third photovoltaic panel 26 can be removed, and then the incident light of the photovoltaic panel can be increased by cleaning the surface of the photovoltaic panel, thereby improving the detection efficiency to a certain extent.
