[0002] Solar photovoltaic panels are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).
[0003] In the prior art, solar photovoltaic panels, under the action of the lower bracket, generally have pitch angle adjustment and rotation adjustment functions, so that the solar panels can move with the sun to ensure optimal lighting, and solar photovoltaic panels have many application scenarios; for some self-driving vehicles, photovoltaic panels are generally laid on the upper end to supplement the power supply for the vehicle, and these photovoltaic panels lack an angle adjustment mechanism that is compatible with them; the solar panels on the upper end of these vehicles are generally laid flat, although the vehicle can turn around and move at will as needed to change the position of the solar panels, but the vehicle is generally not moving during camping, and if the solar panel cannot be adjusted in angle, its power generation efficiency is low, and if the ground solar panel angle adjustment bracket is simply installed on the upper end of the vehicle, since the height of the bracket in the prior art will take up a lot of space, it will seriously affect the vehicle's passability. Therefore, a structure that can be used for vehicle solar panel angle adjustment is needed to address this problem. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. When the pitch angle of the solar panel does not need to be adjusted, the entire solar panel can be completely flat on the upper end of the bottom plate. In this way, the solar panel occupies less height after being folded, and is suitable for installation on the top of a vehicle, without affecting the vehicle's passability.
[0014] 2.

[0023] An inflating mechanism for inflating the airbag 6 is arranged on one side of the airbag 6 inside the cavity 5, and the inflating mechanism includes an inflating chamber 9, a piston 10, and an electric push rod 11. An inflating chamber 9 is fixedly arranged on one side of the airbag 6 inside the cavity 5, and a piston 10 is arranged inside the inflating chamber 9. An electric push rod 11 is fixedly arranged on one side of the inflating chamber 9 inside the cavity 5. The inflating mechanism can be used to conveniently inflate the airbag 6; thereby, the folds of the airbag 6 can be propped up, so that the airbag 6 expands upward, thereby pushing the solar panel 4 to rotate around the first rotating shaft 2, so that the pitch angle of the solar panel 4 can be adjusted. Although the solar panel 4 moves along an arc when rotating around the first rotating shaft 2, since the airbag 6 is soft, it can be deformed to a certain extent, so that no motion interference will occur;
[0024] The movable end of the electric push rod 11 is fixedly connected to the piston 10; the piston 10 can be driven to move left and right inside the gas chamber 9 by the contraction of the electric push rod 11; it should be noted that the gas chamber 9 is a complete cavity. Figure 4 The middle air filling chamber 9 is a cross-sectional view;
[0025] The inflatable chamber 9 is fixedly connected to the inflatable tube 8, and the interior of the inflatable chamber 9 is connected to the interior of the airbag 6 through the inflatable tube 8; the air inside the inflatable chamber 9 can be guided into the interior of the airbag 6 through the inflatable tube 8;
[0026] The piston 10 is movably engaged and arranged inside the gas chamber 9; the gas chamber 9 can function as a syringe through the piston 10, and when the piston 10 moves, the air inside the gas chamber can be pushed into the airbag 6;
[0027] A second rotating shaft 12 is fixedly arranged at the middle of the lower end of the bottom plate 1, and the bottom plate 1 and the solar panel 4 at the upper end can be conveniently rotated through the second rotating shaft 12, so that the rotation angle of the solar panel 4 can be conveniently adjusted; it should be noted that the second rotating shaft 12 should pass through the roof of the vehicle during installation, and then the second rotating shaft 12 and the roof of the vehicle should be connected through a bearing and waterproofed; in this way, the second rotating shaft 12 will not occupy the height space of the entire device, which can ensure that the height of the device is small and will not affect the passability of the vehicle;
[0028] A sealing ring gasket 13 is fixedly arranged between the second rotating shaft 12 and the bottom plate 1, and the sealing ring gasket 13 can ensure the sealing of the installation position when the device is installed on the upper end of the vehicle;
[0029] Working principle: When using the device, first install the device, and install the second rotating shaft 12 on the upper end of the roof of the vehicle during installation, so that the rotation angle of the solar panel 4 can be easily adjusted; it should be noted that the second rotating shaft 12 should pass through the roof of the vehicle during installation, and then the second rotating shaft 12 and the roof of the vehicle are connected through a bearing and waterproofed; in this way, the second rotating shaft 12 will not occupy the height space of the entire device, which can ensure that the height of the device is small and will not affect the trafficability of the vehicle;
[0030] The pitch angle adjustment mechanism of the subsequent device can not only adjust the pitch angle of the solar panel 4, but also the entire solar panel 4 can be completely flat on the upper end of the bottom plate 1 when not in use, so that the height occupied by the solar panel 4 after folding is small, and it is suitable for installation on the top of the vehicle, and will not affect the vehicle's passability; compared with the traditional bracket-type solar panel 4 angle adjustment bracket; even if the traditional bracket drives the solar panel 4 to fold, the bracket itself still occupies a lot of space;
[0031] When the pitch angle of the solar panel 4 needs to be adjusted, the adjustment should be made when the camping vehicle does not need to be driven in the campsite to ensure safety. During the adjustment, the piston 10 is pushed by the electric push rod 11 to move inside the air chamber 9, so that the air inside the air chamber 9 can be squeezed into the air bag 6. Thus, the folds of the air bag 6 can be propped up, so that the air bag 6 can expand upward, so that the solar panel 4 can be pushed to rotate around the first rotation axis 2, so that the pitch angle of the solar panel 4 can be adjusted. Although the solar panel 4 moves along an arc when rotating around the first rotation axis 2, since the air bag 6 is soft, it can be deformed and bent to a certain extent, so that no motion interference will occur.
[0032] It should be noted that when the airbag 6 is installed in the device in the figure, it is installed at a position inside the cavity 5 away from the first rotating shaft 2. In this way, the airbag 6 can drive the solar panel 4 to rotate a smaller angle only when it is expanded to a greater extent. If it is necessary to expand the rotatable angle of the solar panel 4, the airbag 6 can be installed close to the first rotating shaft 2 when designing and producing the device. In this way, the airbag 6 only needs to be slightly expanded to drive the solar panel 4 to adjust to a larger angle.
