Description

Technical Field

[0001] This invention belongs to the field of photovoltaic modules, and particularly relates to a photovoltaic module frame fixing structure. Background Technology

[0002] Currently, to ensure that photovoltaic modules can be installed securely and are not affected by external forces causing them to shake or fall off, the main installation methods for photovoltaic modules are either using clamps or using screws and nuts to fix the modules to the bracket rails to achieve an overall connection with the bracket. This method requires auxiliary tools for tightening and a large number of clamps and screws and nuts. The stress generated during the operation may cause microcracks and damage to the modules, and the extensive use of clamps and fixing screws and nuts will also increase the installation cost. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the present invention provides a photovoltaic module frame fixing structure. To achieve the above objective, the present invention provides the following technical solution:

[0004] A photovoltaic module frame fixing structure includes: a frame, fixing feet, a base, and limiting members. The bottom of the frame is provided with multiple fixing feet, and the frame is mounted on the base through the fixing feet. The base is provided with multiple slots, and the multiple fixing feet are connected to the multiple slots in a one-to-one correspondence. Each slot is provided with a limiting member, and the limiting member includes at least one limiting surface and at least one interference fit surface. The limiting surface fits against the side of the fixing foot, and the interference fit surface is interference-fitted with the fixing foot.

[0005] Furthermore, the fixed support leg includes a connecting part and a limiting part, the limiting part being used for interference fit with the limiting member, and the connecting part connecting the limiting part and the frame.

[0006] Furthermore, the fixed support leg is in the shape of a "T" or "L".

[0007] Furthermore, the slot includes a guide groove and an insertion groove, the fixed support can be inserted into the insertion groove, and the fixed support can move along the guide groove after being inserted into the insertion groove.

[0008] Furthermore, the limiting component includes a baffle and two support platforms. The two support platforms are symmetrical about the central plane of the baffle. The two support platforms are integrally formed or fixedly connected to the baffle. The limiting surface is provided on the baffle, and the interference fit surface is provided on the support platforms.

[0009] Furthermore, one side of the interference fit surface is provided with a bevel.

[0010] Furthermore, an elastic gasket is provided on the interference fit surface.

[0011] Furthermore, one end of the elastic pad is provided with a protrusion.

[0012] Furthermore, the support platform is provided with multiple mounting holes.

[0013] The technical effects and advantages of this invention are as follows:

[0014] By introducing a snap-fit ​​structure into the photovoltaic module frame, the amount of aluminum profile used in the frame can be reduced without altering the frame's stress distribution. Furthermore, the modules can be directly connected and fixed via the snap-fit ​​structure during installation, replacing traditional clamping blocks or screws and nuts. This avoids microcracks and damage to the modules caused by external forces when tightening nuts with auxiliary tools during installation. This invention improves module installation efficiency and quality, thereby significantly reducing installation costs.

[0015] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Furthermore, in this invention, the terms "first," "second," and other similar words are not intended to imply any order, quantity, or importance, but are merely used to distinguish different elements, and the terms "upper," "lower," "left," "right," and other similar words are merely positional relationships in the accompanying drawings.

[0024] like Figure 1 As shown in the figure, an embodiment of the present invention discloses a photovoltaic module frame fixing structure, including: a frame 2, fixing feet 3, a base 4, and a limiting member 6. The bottom of the frame 2 is provided with multiple fixing feet 3, and the frame 2 is mounted on the base 4 through the fixing feet 3. The base 4 is provided with multiple slots 5, and the multiple fixing feet 3 are connected to the multiple slots 5 in a one-to-one correspondence. Each slot 5 is provided with a limiting member 6, and the limiting member 6 includes at least one limiting surface and at least one interference fit surface. The limiting surface fits against the side of the fixing foot 3, and the interference fit surface fits the fixing foot 3, thereby fixing the entire frame 2.

[0025] like Figure 2 As shown, the battery panel 1 is installed inside the frame 2, and the frame 2 is fixed by multiple fixed feet 3.

[0026] like Figure 4 As shown, the fixed support leg 3 includes a connecting part and a limiting part. The limiting part is used to have an interference fit with the limiting member 6, and the connecting part connects the limiting part and the frame 2.

[0027] Based on the above description of the fixed support leg 3, for example, the fixed support leg 3 can be "T" shaped or "L" shaped.

[0028] like Figure 3 As shown, the slot 5 includes a guide groove and an insertion groove. The fixed leg 3 can be inserted into the insertion groove, and after being inserted into the insertion groove, the fixed leg 3 can move along the guide groove. After the fixed leg 3 moves to the guide groove, the fixed leg can no longer be moved vertically out of the slot 5.

[0029] like Figure 5As shown, in one embodiment of the present invention, the limiting member 6 includes a baffle 61 and two support platforms 62. The baffle 61 serves to limit and support the movement, and the lower surface of the support platform 62 can be interference-fitted with the fixed leg 3. The two support platforms 62 are symmetrical about the central plane of the baffle 61. The two support platforms 62 are integrally formed or fixedly connected to the baffle 61. The limiting surface is provided on the baffle 61, and the interference-fit surface is provided on the support platform 62. One side of the interference-fit surface has an inclined surface, which facilitates the movement of the limiting part of the fixed leg 3 to the interference-fit surface. An elastic gasket 64 is provided on the interference-fit surface. The elastic gasket 64 can prevent damage to the support platform 62 and the fixed leg 3 during the interference fit. One end of the elastic gasket 64 has a protrusion, which can restrict the movement of the fixed leg 3 after installation. The support platform 62 has multiple mounting holes 63, through which the limiting member 6 is installed onto the base 4.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
