[0027] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this application. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0028] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures.

The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0030] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 This is a schematic diagram of a frame reinforcement structure provided in this embodiment; Figure 2 This is a schematic diagram illustrating a usage scenario of the frame reinforcement structure provided in this embodiment; Figure 3 This is a schematic diagram of the structure of a photovoltaic module frame provided in this embodiment; Figure 4 This is a schematic diagram of a frame mounting structure provided in this embodiment.

[0031] See Figure 1 This embodiment provides a frame reinforcement structure 10, including a cavity 1, which is surrounded by a top wall 2, an inner wall 3, a bottom wall 4 and an outer wall 5 connected in sequence. Figure 1 , Figure 2 In the diagram, the X direction represents the vertical direction upward along the top wall 2, and the Y direction represents the horizontal direction to the right along the top wall 2. In some embodiments, the cavity 11 is made of aluminum profile, or it may be made of other composite materials.

[0032] The outer surface of the top wall 2 has a recessed adhesive channel 21. This improves the sealing performance between the photovoltaic module and the frame reinforcement structure. For example, see... Figure 2 Sealant 23 is applied to the gap between the outer surface of the top wall 2 and the photovoltaic module 24. When the photovoltaic module 24 comes into contact with the sealant 23, part of the sealant 23 flows to the inner wall 3, while the other part accumulates in the guide groove 21 as it flows to the outer wall 5, so that the sealant 23 will not overflow to the outer wall 5. This ensures the aesthetics and sealing performance of the product.

[0033] Continue to refer to Figure 1The cavity 1 is provided with reinforcing ribs 22, which divide the cavity 1 to form at least one sub-cavity 11. In some embodiments, one end of the reinforcing rib 22 is connected to a first connection point a between the top wall 2 and the outer wall 5, and the other end of the reinforcing rib 22 is connected to a second connection point b between the bottom wall 4 and the inner wall 3. The reinforcing rib 22 may be made of solid aluminum profile or other materials.

[0034] The advantage of this is that the design of the reinforcing rib 22 enhances the stress stability of the frame reinforcement structure 10. Since the original shape of the cavity 1 is rectangular, by connecting the two ends of the reinforcing rib 22 to the first connection point a and the second connection point b respectively, the cavity 1 can be divided into two triangles along the diagonal of the rectangle. This makes the frame reinforcement structure 10 have stronger bending and torsional resistance.

[0035] In some embodiments, the distance between the projection position of the first connection point a in the horizontal direction along the top wall 2 and the adhesive guide groove 21 is less than the distance between the projection position of the second connection point b in the horizontal direction along the top wall 2 and the adhesive guide groove 21.

[0036] In some embodiments, such as Figure 1 The distance d1 between the edge of the adhesive guide groove 21 near the outer wall 5 and the outer wall 5 is 3mm-5mm. The cross-section of the adhesive guide groove 21 is arc-shaped, and the width of the adhesive guide groove 21 is not less than 5mm.

[0037] Furthermore, the depth h of the adhesive guide groove 21 is not less than one-third of the wall thickness H of the top wall 2, and the depth h of the adhesive guide groove 21 is not greater than one-half of the wall thickness H of the top wall 2. For example, in this embodiment, the wall thickness H of the top wall 2 is 3mm, then 1mm ≤ h ≤ 1.5mm.

[0038] The advantage of this is that by placing the adhesive guide groove 21 close to the outer wall 5, the sealant 23 will accumulate in the adhesive guide groove 21 only after filling the gap between the outer surface of the top wall 2 and the photovoltaic module 24, thus ensuring the sealing performance of the photovoltaic product.

[0039] See Figure 3 This embodiment also provides a photovoltaic module frame 1000. The photovoltaic module frame 1000 includes a long frame 200 and a short frame 100 abutting against one side of the long frame 200, with a corner bracket 300 installed between the long frame 200 and the short frame 100. For example... Figure 3 A rectangular border is formed by four corner brackets 300 between a pair of long borders 200 and a pair of short borders 100.

[0040] See also Figure 3 The short frame 100 includes a frame reinforcement structure 10 and two frame mounting structures 20 respectively connected to the two ends of the frame reinforcement structure 10. Figure 3In the diagram, the Y direction is used to indicate the horizontal direction to the right along the short border 100, and the X direction is used to indicate the vertical direction upward along the short border 100.

[0041] like Figure 1 As shown, the frame reinforcement structure 10 includes: a cavity 1, which is formed by a top wall 2, an inner wall 3, a bottom wall 4 and an outer wall 5 connected in sequence; the outer surface of the top wall 2 is provided with a recessed adhesive guide groove 21; the cavity 1 is provided with a reinforcing rib 22, which divides the cavity 1 to form at least one sub-cavity 11.

[0042] Continue to refer to Figure 1 In some embodiments, the distance between the projection of the first connection point a along the horizontal direction of the top wall 2 and the adhesive guide groove 21 is less than the distance between the projection of the second connection point b along the horizontal direction of the top wall 2 and the adhesive guide groove 21. In some embodiments, the cavity 1 and the two side frame mounting structures 20 are made of aluminum profiles. The advantage of this is that the cavity 1 can be divided into two triangles along the diagonal of the rectangle, which makes the side frame reinforcing structure 10 have stronger bending and torsional resistance.

[0043] Continue to refer to Figure 1 In some embodiments, one end of the reinforcing rib 22 is connected to a first connection point a between the top wall 2 and the outer wall 5, and the other end of the reinforcing rib 22 is connected to a second connection point b between the bottom wall 4 and the inner wall 3.

[0044] In some embodiments, such as Figure 1 The distance d1 between the edge of the adhesive guide groove 21 near the outer wall 5 and the outer wall 5 is 3mm-5mm. The cross-section of the adhesive guide groove 21 is arc-shaped, and the width w of the adhesive guide groove 21 is not less than 5mm. In addition, the depth h of the adhesive guide groove 21 is not less than one-third of the wall thickness H of the top wall 2, and the depth h of the adhesive guide groove 21 is not greater than one-half of the wall thickness H of the top wall 2. For example, in this embodiment, the wall thickness H of the top wall 2 is 3mm, then 1mm ≤ h ≤ 1.5mm.

[0045] Since deformation in the short frame 100 often occurs in the middle, the two frame mounting structures 20 connected to both ends of the frame reinforcement structure 10 do not need to use reinforcing ribs. For example, as Figure 4 As shown, the aforementioned frame mounting structure 20 may include a first sidewall 201, a second sidewall 202, a third sidewall 203, and a fourth sidewall 204. Figure 4In the diagram, the Y direction represents the horizontal direction to the right along the first sidewall 201, and the X direction represents the vertical direction upward along the first sidewall 201. In this embodiment, the first sidewall 201, second sidewall 202, third sidewall 203, and fourth sidewall 204 can be arranged into a rectangle corresponding to the frame reinforcement structure 10. This rectangle is hollow to save costs. Similarly, the material of the frame mounting structure 20 can be aluminum profile or other composite materials; there are no restrictions on this.

[0046] Continue to refer to Figure 4 In some embodiments, the minimum distance d2 between the edge of the border reinforcement structure 10 and the edge of the short border 100 is not greater than 100mm.

[0047] For example, in this embodiment, the length of the short frame 100 is 1100mm, and the length of the frame reinforcement structure 10 along the length direction of the short frame 100 is 900mm. The distance between the left edge of the frame reinforcement structure 10 and the left edge of the short frame 100 is 100mm, and the distance between the right edge of the frame reinforcement structure 10 and the right edge of the short frame 100 is 100mm.

[0048] The advantage of this is that the design of the reinforcing rib 22 enhances the stress stability of the frame reinforcement structure 10. The frame reinforcement structure 10 is located in the middle of the short frame 100, thereby reducing the probability that the short frame 100 will deform after being subjected to the squeezing force from the two corner brackets 300 and the long frame 200. This helps the sealant to better fill the gaps, thereby improving the sealing performance and appearance of the product.

[0049] The above embodiments can achieve the following beneficial effects:

[0050] The frame reinforcement structure and photovoltaic module frame provided by this utility model, through the design of adding reinforcing ribs inside the cavity, give the frame reinforcement structure stronger bending and torsional resistance, reducing the risk of deformation or damage during frame installation and transportation. At the same time, the design of adhesive guide grooves on the outer surface of the top wall prevents sealant from overflowing, improving the sealing performance and aesthetic appearance of the photovoltaic product after gap filling.
