In addition, during daily use, if the vehicle is exposed to strong sunlight or high temperatures, a large amount of solar energy will be transmitted into the vehicle in the form of solar heat. Not only will it fail to be effectively collected and utilized, but it will also significantly reduce the comfort of driving and riding.

[0044] Example

[0045] In order to address the problems that existing photovoltaic sunshades generally have, such as non-extendable and non-foldable structures, insufficient space utilization, difficulty in efficiently adapting to vehicle roof space, and inability to fully realize the photovoltaic utilization potential and practical sunshade value of the vehicle roof area;

[0046] refer toFigures 1-3 As shown, this application discloses a vehicle-mounted multi-directional telescopic solar photovoltaic sunshade, including a base assembly 10, a multi-directional telescopic assembly 20, and a photovoltaic panel assembly 30;

[0048] The left and right unfolding drive mechanism 21 includes two left and right drive components 211 respectively located on the back of the base assembly 10 at the front and rear, and two left and right telescopic tubes 212 respectively located on the front and rear sides of the base assembly 10;

[0049] The front and rear deployment drive mechanism 22 includes two front and rear drive components 221 respectively located on the left and right sides of the base assembly 10, and two front and rear telescopic tubes 222 respectively located on the outside of the two front and rear drive components 221;

[0050] The left and right driving parts of each left and right drive assembly 211 are respectively connected to the non-telescopic sections of the two front and rear telescopic tubes 222; the front and rear driving parts of each front and rear drive assembly 221 are respectively connected to the non-telescopic sections of the two left and right telescopic tubes 212; the telescopic ends of the two front and rear telescopic tubes 222 are connected to the telescopic ends of the two left and right telescopic tubes 212 one by one.

[0051] Based on the above structural design of the multi-directional telescopic assembly 20, under the drive of the two left and right drive components 211, the two front and rear telescopic tubes 222 can move left and right synchronously with the two left and right telescopic tubes 212. Under the drive of the two front and rear drive components 221, the two left and right telescopic tubes 212 can move back and forth with the two front and rear telescopic tubes 222.

In addition, based on the above structural design of the photovoltaic panel assembly 30, the photovoltaic panel of this application has as many as nine panels.

[0053] For the convenience of those skilled in the art, please refer to...

[0054] When the sunshade is opened, first control the two left and right drive components 211 to drive the two front and rear telescopic tubes 222 to move left and right. During this process, the third, fourth, and seventh photovoltaic panels will move to the left synchronously, and the fifth, sixth, and eighth photovoltaic panels will move to the right. Then control the two front and rear drive components 221 to drive the two left and right telescopic tubes 212 to move forward and backward. During this process, the first, fourth, and sixth photovoltaic panels will move forward, and the second, third, and fifth photovoltaic panels will move backward. After all the photovoltaic panels have moved into position, they will form a rectangular structure (maximum light-receiving area) with the ninth photovoltaic panel.

[0055] Conversely, the working principle of closing the awning will not be elaborated here.

[0056] Regarding the dimensions of the photovoltaic panels set above, this application preferably sets them as follows:

One second motor 2211 drives a front and rear lead screw 2212 to rotate, causing the front and rear push tube 2213 connected to it to drive a left and right telescopic tube 212 to move forward. The other second motor 2211 drives a front and rear lead screw 2212 to rotate, causing the front and rear push tube 2213 connected to it to drive another left and right telescopic tube 212 to move backward. During this process, the first, fourth, and sixth photovoltaic panels will move forward, and the second, third, and fifth photovoltaic panels will move backward.

When the third, fourth, and seventh photovoltaic panels move to the left synchronously and when the fifth, sixth, and eighth photovoltaic panels move to the right, the two second push rods 221a of each front and rear drive assembly 221 are activated synchronously. One second push rod 221a drives one left and right telescopic pipe 212 to move forward, and the other second push rod 221a drives another left and right telescopic pipe 212 to move backward. During this process, the first, fourth, and sixth photovoltaic panels will move forward, and the second, third, and fifth photovoltaic panels will move backward.

Two left and right telescopic tubes 212 are installed with the two front and rear drive parts of the front and rear drive assembly 221. When the left and right telescopic tubes 212 are in the retracted state, the two telescopic ends of the left and right telescopic tubes 212 can be retracted into the left and right telescopic sleeves 2121. Similarly, through the above-mentioned front and rear telescopic sleeves 2221, it is possible to ensure that the two front and rear telescopic tubes 222 are installed with the two left and right drive parts of the left and right drive assembly 211 without affecting the front and rear telescopic tubes 222's front and rear telescopic extension and retraction.
