The two bases can be folded or unfolded for use. After folding, the two photovoltaic panels respectively fixed on the two photovoltaic panel brackets are facing each other, which can reduce the occupied space and facilitate transportation. A plurality of locking protrusions are provided on the back of the two photovoltaic panel brackets.

In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0068] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0069] See also Figures 1 to 7 A foldable photovoltaic panel support with adjustable illumination angle provided in one embodiment of the utility model includes a base 1, a first support plate 2, a second support plate 3, a first support assembly 4, a second support assembly 5, a first adjustment assembly 6 and a second adjustment assembly 7.

[0071] The first adjustment assembly 6 includes a first adjustment rod 61 and a first transmission wheel set 62, and the first adjustment rod 61 is connected to the first support plate 2 through the first transmission wheel set 62. The second adjustment assembly 7 includes a second adjustment rod 71 and a second transmission wheel set 72, and the second adjustment rod 71 is connected to the second support plate 3 through the second transmission wheel set 72.

[0072] When the first adjusting rod 61 drives the first transmission wheel set 62 to rotate, the first support plate 2 can rotate relative to the base 1 , and when the second adjusting rod 71 drives the second transmission wheel set 72 to rotate, the first support plate 2 can rotate relative to the second support plate 3 .

The first support assembly 4 supports the first support plate 2, and the second support assembly 5 supports the second support plate 3. When the elevation angle of the first photovoltaic panel and the second photovoltaic panel needs to be adjusted, the first adjustment rod 61 is operated to drive the first transmission wheel group 62 to rotate, so that the first support plate 2 can rotate relative to the base 1, and the second support plate 3 connected to the first support plate 2 rotates synchronously, so that the elevation angle of the first photovoltaic panel and the second photovoltaic panel can be conveniently adjusted, without the need to manually support the first support plate 2 and the second support plate 3 to promote the rotation. When the first photovoltaic panel and the second photovoltaic panel need to be folded, the second adjustment rod 71 is operated to drive the second transmission wheel group 72 to rotate, so that the second support plate 3 can rotate relative to the first support plate 2, so that the first photovoltaic panel and the second photovoltaic panel can be conveniently folded, without the need to manually support the second support plate 3 to promote the rotation.

Therefore, the elevation angle can be adjusted and folded by driving the first adjustment assembly 6 and the second adjustment assembly 7, which is more convenient and labor-saving.

[0074] It is understandable that since the angles of sunlight at different latitudes are different, the first photovoltaic panel and the second photovoltaic panel can be adjusted to match the angle of sunlight, thereby improving the efficiency of obtaining sunlight and greatly shortening the maximum working time of the solar panel for the load. Folding can reduce the occupied space and facilitate storage or transportation.

[0086] See also Figure 1 , Figure 3 , Figure 6 and Figure 7 The foldable photovoltaic panel support with adjustable illumination angle further includes a first locking mechanism 8 and a second locking mechanism 9. The first locking mechanism 8 is used to lock the first support plate 2 to prevent the first support plate 2 from rotating relative to the base 1, so that the first support plate 2 remains at the adjusted elevation angle position, or the first locking mechanism 8 is used to unlock the first support plate 2 to allow the first support plate 2 to rotate relative to the base 1, so that the elevation angle of the first support plate 2 can be adjusted.

And when the first support plate 2 is adjusted to different elevation angles, the limit rod 81 can be inserted into the limit holes 811 at different positions to ensure that the first support plate 2 can be locked. In this embodiment, the lock hole 411 and the limit hole 811 are both threaded holes, and the limit rod 81 is a bolt. In this embodiment, the first locking mechanism 8 is provided with two groups, which are respectively arranged on both sides of the first support plate 2.

[0088] The second locking mechanism 9 is used to lock the second support plate 3 to prevent the second support plate 3 from rotating relative to the first support plate 2, so that the second support plate 3 remains in the unfolded position. Alternatively, the second locking mechanism 9 is used to unlock the second support plate 3 to allow the second support plate 3 to rotate relative to the first support plate 2 for folding.

[0089] The second locking mechanism 9 includes an adjusting tube 91, a locking tube 92 and an adjusting latch 93. The adjusting tube 91 is fixedly connected to the first supporting plate 2, and an adjusting groove 911 and a locking groove are provided on the tube wall of the adjusting tube 91. The adjusting groove 911 extends along the axial direction of the adjusting tube 91, and the locking groove extends along the circumferential direction of the adjusting groove 911. The locking groove is connected to the adjusting groove 911, and two locking grooves are provided at intervals along the axial direction of the adjusting tube 91.

When the handle 932 drives the rod 931 to move and the handle 932 enters the first locking groove 912, the rod 931 is inserted into the locking tube 92 to prevent the second support plate 3 from rotating relative to the first support plate 2. When the handle 932 drives the rod 931 to move and the handle 932 exits the second locking groove 913, the rod 931 exits the locking tube 92 to allow the second support plate 3 to rotate relative to the first support plate 2. Thus, the second support plate 3 can be unlocked and locked by moving the adjustment pin 93. And because the locking tube 92 and the adjustment tube 91 are coaxially arranged, when the rod 931 is inserted into the locking tube 92 in the locked state, the first support plate 2 and the second support plate 3 can be adjusted to be flush, so that the maximum area can absorb sunlight after unfolding.
