Description

Solar module frame

The invention relates to a structural improvement of a solar module frame, and in particular to a solar module frame with good drainage capability.

The solar module frame is generally composed of four frames and four L-shaped support structures (also known as L-Key). However, after actual use, it is found that when solar modules are placed in areas with large climate change, the solar modules continue to accumulate repeatedly condensed water and ice due to poor drainage of the frame, resulting in deformation and damage of the solar module frame. In addition, even if it is placed in a region with less climate change, the problem of poor drainage can cause dust to be carried away by rainwater and the like, and accumulate on the solar module, even if the module is overheated and burned due to shading.

Therefore, there is an urgent need to seek to improve the structure of the solar module frame to reduce the probability of occurrence of the above problems.

The invention provides a solar module frame which can help drainage and thereby prevent the occurrence of shading.

The solar module frame of the present invention comprises a plurality of frames and a plurality of L-shaped support structures, wherein the frame surrounds the solar modules and the frames are combined by an L-shaped support structure. The top of each frame has a bevel, and the L-shaped support structure is an integrally formed metal structure, and the top mask at the corner of the L-shaped support structure has a guide groove.

In an embodiment of the invention, the width of the guiding grooves may be the same.

In an embodiment of the invention, the guide groove is connected to a slope of each frame.

In an embodiment of the invention, the outer side edge of the L-shaped support structure may also be provided with a cut surface.

In an embodiment of the invention, the L-shaped support structure includes two engaging arms, and each of the engaging arms has a toothed structure.

In an embodiment of the invention, the tilt angle is, for example, between 10° and 60°.

In an embodiment of the invention, the L-shaped support structure is made of aluminum.

Based on the above, the solar module frame of the present invention can provide drainage when it is raining or snowing because the guide groove is provided at the top surface of the corner of the L-shaped support structure, and the dust on the frame can be taken away by drainage. To reduce the risk of shading.

The above described features and advantages of the invention will be apparent from the following description.

1 is a plan view of a solar module frame in accordance with an embodiment of the present invention.

Referring to FIG. 1, the solar module frame of the present embodiment includes a plurality of frames 100 and a plurality of L-shaped support structures 102, wherein the L-shaped support structures 102 are, for example, aluminum structures or other suitable materials. The bezel 100 can enclose the solar module 104 and combine the bezels 100 by the L-shaped support structure 102. The top 100a of each bezel 100 has a bevel 106. The top surface 102a at the corner of the L-shaped support structure 102 has a guide groove 108 to help drain water when it is raining or snowing, and the dust on the frame 100 can be taken away by drainage to reduce the risk of shading. In Fig. 1, the guide grooves 108 are connected to the inclined surface 106 of each of the bezels 100, so that the function of drainage can be further enhanced, and the width W of the guide grooves 108 is, for example, the same. Moreover, the L-shaped support structure 102 of the present embodiment is an integrally formed metal structure, so that not only excellent mechanical strength and weather resistance but also oxidation problems due to chemical potential difference when using different (metal) materials can be prevented. In addition, the outer side edge of the L-shaped support structure 102 may be provided with a cut surface 110 to avoid damage caused by scratching or impact during handling and assembly.

Figure 2 is an enlarged perspective view of the L-shaped support structure of Figure 1. An L-shaped support structure 102 is shown separately in FIG. 2 having two engagement arms 112 for engaging the bezel 100 on both sides. Thus, the engagement arms 112 can also be designed to have a toothed structure 114 as shown in FIG. 3 to aid in tight engagement with the bezel 100. In addition, an accommodating groove 200 is disposed inside the L-shaped support structure 102 for accommodating a solar panel (solar module).

Figure 4 shows an enlarged cross-sectional view of the bezel of Figure 1. It can be observed from FIG. 4 that in order to enhance the drainage effect, the inclined surface 106 of the top 100a of the bezel 100 and the top surface of the solar module (104 of FIG. 1) have an inclination angle θ, for example, between 10° and 60°. between. In addition, a receiving groove 400 is also disposed inside the frame 100 for accommodating the solar panel (solar module).

Figure 5 is an exploded perspective view of a bezel and an L-shaped support structure in accordance with an embodiment of the present invention. The manner in which the bezel 100 and the L-shaped support structure 102 are combined can be observed from FIG. 5, wherein the bezel 100 has an engagement space 116 so that the engagement arms 112 of the L-shaped support structure 102 can pass therethrough and can be coupled by the teeth of the arm 112. The structure 114 is tightly engaged with the joint space 116 of the bezel 100 to be assembled into the solar module frame of FIG.

In summary, the L-shaped support structure of the present invention is provided with a guide groove at the top surface of the corner, so that it can help drainage when it is raining or snowing, and thereby take away the dust on the frame to reduce the risk of shading. And to prevent deformation and damage of the frame caused by the continuous accumulation of repeatedly condensed water and ice by the solar module. Moreover, the top of the bezel of the present invention is also provided with a bevel, so that the drainage effect of the bezel can also be improved. Further, since the L-shaped support structure of the present invention is an integrally formed metal structure, it is excellent in both mechanical strength and weather resistance.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
