The photovoltaic module 100 has a first bracket 110, a second bracket 112, a first photovoltaic panel 120, and two first return elastic members 130 (described later in FIG. 3). The second bracket 112 is disposed opposite to the first bracket 110. For example, the second bracket 112 and the first bracket 110 may be disposed on two sides of the first photovoltaic panel 120 in parallel, or may be disposed on both sides without being parallel. The first bracket 110 and the second bracket 112 may, for example, be elongated so that one or more photovoltaic panels may be disposed between the first bracket 110 and the second bracket 112.

The first end portion 1201 and the second end portion 1202 of the first photovoltaic panel 120 are pivotally fixed to the first bracket 110 and the second bracket 112 respectively, that is, as shown in FIG. 2, the first photovoltaic panel 120, which can be rotated relative to the first bracket 110 and the second bracket 112 as shown in FIG. 2, when the photovoltaic module 100 is subjected to a large wind force, or other external force, such as the weight of snow accumulated on the photovoltaic module 100. . Under appropriate conditions, the first photovoltaic panel 120 is rotated (see Figure 2). In turn, the force exerted on the photovoltaic module 100 can be eliminated, and the risk of damage to the system caused by the photovoltaic module 100 directly resisting external forces is reduced. Specifically, if the rotation of FIG. 2 is generated, the airflow of the strong wind can be relatively easily passed through the photovoltaic module 100, and the weight of the snow accumulated on the module can also be changed through the angle of the first photovoltaic panel 120. Slide down to the mounting base G.

In addition, in order to enable the reset effect of the first photovoltaic panel 120 in a normal situation, to return to the angle of the preferred power generation/absorption solar energy set when the photovoltaic module 100 is installed, the photovoltaic module 100 Also included are two first return elastic members 130.

Referring to FIG. 4A and FIG. 4B together, FIG. 4A and FIG. 4B are partial detailed structural views of the elastic member according to the embodiment of the present invention. Each of the first return elastic members 130 respectively abuts the first end portion 1201 and the second end portion 1202 of the first photovoltaic panel 120 to provide a resetting force of pivoting of the first photovoltaic panel 120. For example, the elastic means through which the first return elastic member 130 can pass can be designed and matched with elastic devices such as springs, elastic belts, etc. through various mechanical structures based on the technical contents disclosed in the present disclosure and the background knowledge of those skilled in the art. When the first photovoltaic panel 120 rotates as shown in FIG. 2, a deformation of the stretching or contraction occurs on the elastic device, thereby generating an opposite resetting force.

As described above, the structure disclosed in the figure can be applied to the specific implementation of each of the above-mentioned reset elastic members. The first return elastic member 130 and the second return elastic member 132 have a joint portion 133 and a joint portion 135. The joint portion 133 is fixed to the first bracket 110 or the second bracket 112, and the joint portion 135 is fixed to the photovoltaic panels 120 and 122. The portion 133 and the joint portion 135 are pivotally connected to each other.

For example, the first reset elastic member 130 is disposed on two sides of the first photovoltaic panel 120, and the second reset elastic member 132 is disposed on two sides of the second photovoltaic panel 122. The joint portion 133 of the first return elastic member 130 and the second return elastic member 132 on one side of the photovoltaic panel 122 is fixed to the first bracket 110, and the first return elastic member 130 and the second return elastic member on the other side. The joint portion 133 of the 132 is fixed to the second bracket 112.

Therefore, the first photovoltaic panel 120 and the second photovoltaic panel 122 can be pivotally fixed to the first bracket 110 and the second bracket 112 through the first return elastic member 130 and the second return elastic member 132.

Referring to FIG. 5 again, the joint portion 133 and the joint portion 135 can be pivotally connected to each other through the pivot rod 134. For example, one end of the pivot rod 134 can be locked on one of the joint portion 133 and the joint portion 135. That is, one end of the pivot lever 134 is inseparable from one of the joint portion 133 and the joint portion 135. The joint portion 133 and the joint portion 135 each have a groove for receiving the other end of the pivot rod 134.

Furthermore, please refer to FIG. 5 and FIG. 6 together. FIG. 6 is a spring structure diagram of an embodiment of the present invention. The first return elastic member 130 and the second return elastic member 132 may have a return spring 136 through which the pivot rod 134 passes, and one end of the return spring 136 abuts against the joint portion 133, and the other end of the return spring 136 abuts against the joint Part 135. Therefore, when the photovoltaic panels 130, 132 are subjected to external force application to generate rotation, the joint portion 133 and the joint portion 135 are individually fixed to the first photovoltaic panel 120, the second photovoltaic panel 122, and the first bracket 110 or the second bracket. 112, so the corresponding pivoting will also occur (please refer to FIG. 4B). At this time, the return spring 136 will generate a corresponding stretching or contraction, thereby generating the first photovoltaic panel 120 and the second photovoltaic panel. 122 The force required to reset.

In still another embodiment, the joint portion 133 and the joint portion 135 have abutting surfaces 1330 and 1350, and the abutting surfaces 1330 and 1350 abut against the return spring 136. For example, the return spring 136 has an interconnected epitaxial start end 1360, an annular curl 1362, and an epitaxial end 1364. The pivot rod 134 passes through the annular curl 1362, and the epitaxial start end 1360 and the epitaxial end 1364 respectively abut. The abutting surface of the portion 133 and the joint portion 135. Through the epitaxial starting end 1360 and the extension end 1364 respectively abutting the abutting surface of the joint portion 133 and the joint portion 135, a limit position can be generated for the return spring 136, and the return spring 136 can be prevented from being pivoted with the joint portion 133 and the joint portion 135. Turning in turn, the return spring 136 can be caused to compress or stretch when the joint portion 133 and the joint portion 135 are pivoted.

Please refer to FIG. 7A and FIG. 7B. FIG. 7A and FIG. 7B are schematic diagrams showing the installation and operation of a photovoltaic module according to an embodiment of the present invention. The photovoltaic module 100 further includes a third bracket 160. The third bracket 160 supports the photovoltaic module 100 such that one end thereof is farther away from the mounting base G and one end is closer to the mounting base G, so that the photovoltaic module 100 has an inclination angle with the vertical direction D. The first reset elastic member 130 and the second return elastic member 132 are fixed to the first photovoltaic panel 120 and the second photovoltaic panel 122 to provide a reset strength of the first photovoltaic panel 120 and the second photovoltaic panel 122 from the vertical direction D. . For example, as shown in FIG. 7B, if subjected to an external force, the first photovoltaic panel 120 and the second photovoltaic panel 122 are deflected toward the direction perpendicular to the vertical direction D, that is, become parallel with the vertical direction D, first. The resetting force provided by the reset elastic member 130 and the second return elastic member 132 increases as the first photovoltaic panel 120 and the second photovoltaic panel 122 approach the parallel vertical direction. When the external force is weakened or disappears, the restoring force provided by the first return elastic member 130 and the second return elastic member 132 converts the first photovoltaic panel 120 and the second photovoltaic panel 122 to be non-parallel to the vertical direction D. The state, that is, the deviation from the vertical direction D, causes the first photovoltaic panel 120 and the second photovoltaic panel 122 to return to a state closer to that shown in FIG. 7A.

It can also be said that the first photovoltaic panel 120 and the second photovoltaic panel 122 are substantially arranged in a plane by the resetting force of the first return elastic member 130 and the second return elastic member 132. Or substantially arranged in a plane defined by both the first bracket 110 and the second bracket 112.

The second bracket 112 is added. Of course, the parallelism described herein generally means that the light receiving surfaces of the first photovoltaic panel 120 and the second photovoltaic panel 122 are substantially parallel to the plane defined by the first bracket 110 and the second bracket 112.

Please refer to FIG. 8. FIG. 8 is a schematic cross-sectional view of a photovoltaic panel A-A' according to an embodiment of the present invention. The section of A-A' is shown in Figure 1.
