[0051] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0052] Solar energy is the huge energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperatures. Most of the energy needed by humans comes directly or indirectly from the sun. Solar power generation has many unique advantages, such as: solar energy is an inexhaustible energy source, and solar power generation does not produce any waste, noise, greenhouse gas or toxic gases, and is an ideal clean energy; another example: except for the tracking type, the solar power generation system has no moving parts, so the construction period is short, it is not easy to damage, easy to install, simple to maintain, and has a long service life.

[0053] Solar modules are an important part of solar power generation systems, also known as solar panels and photovoltaic modules. Solar modules are made of tempered glass, encapsulation film, cells, encapsulation film and backplane placed in order and pressed into an overall laminated structure by a laminator at a certain temperature. The frame is installed around the solar module to provide support and sealing for the solar module.

[0054] However, the current frames are usually made of aluminum alloy materials, which are hard structures and cannot produce elastic deformation. There will be joints between the solar panels and the frames. If rainwater, dust or other impurities enter the joints, it will affect the use of the solar power generation system. If a large amount of adhesive is used to fill the joints, glue overflow is likely to occur, which will also cause waste of raw materials.

[0055] In order to solve the above-mentioned problems, the present application provides a solar module frame. By setting at least the first end of the guard away from the frame as an elastic material piece, the guard can undergo elastic deformation according to the shape of the solar module when the guard contacts the solar module, thereby avoiding the formation of a splicing seam between the two, preventing the entry of impurities such as rainwater and dust, and reducing the amount of adhesive used for bonding, saving costs while ensuring power generation efficiency.

[0056] The solar panel frame provided in accordance with the present application is described in detail below in conjunction with the accompanying drawings.

[0057] It should be noted that Figures 1 to 3 The x-axis direction is the horizontal direction, the y-axis direction is the vertical direction, and the z-axis direction is the extension direction of the solar module frame 10 .

[0058] An exemplary embodiment of the present application provides a solar module frame 10, such as Figure 1 As shown, the solar panel frame 10 includes a frame body 100 and a sidewall 200. The frame body 100 is surrounded by four sides. The sidewall 200 is arranged on the frame body 100. The sidewall 200 extends from one side of the frame body 100 in a direction away from the frame body 100. The free end of the sidewall 200 is a first end 210, and the end of the sidewall 200 connected to the frame body 100 is a second end 220. At least the first end 210 of the sidewall 200 is set as an elastic material piece, that is, the first end 210 of the sidewall 200 is an elastic material piece, and other parts of the sidewall 200, such as the second end 220, can be elastic material pieces or other non-elastic material pieces.

[0059] The solar panel is installed in a position approximately at a right angle formed by the retaining edge 200 and one side of the frame 100. In this embodiment, by setting at least the first end 210 of the retaining edge 200 away from the frame 100 as an elastic material piece, when the retaining edge 200 contacts the solar panel, the retaining edge 200 can be elastically deformed according to the shape of the solar panel, thereby avoiding the formation of a joint seam between the two, avoiding the entry of impurities such as rainwater and dust, and reducing the amount of adhesive used for bonding, saving costs while ensuring power generation efficiency.

[0060] It should be noted that the elastic material in the present application can be a thermoplastic material, such as PP (polypropylene), nylon, PPO (polyphenylene ether) or HDPE (high-density polyethylene) material, etc. The elastic material can also be a thermosetting resin material with good toughness, such as polyurethane, acrylic resin, epoxy resin, etc., which will not be repeated here.

[0061] In some embodiments, Figure 2 As shown, the entire retaining edge 200 is made of elastic material, and the second end 220 of the retaining edge 200 is connected to the frame 100. Such a design can produce greater deformation and achieve better fit with the solar module.

[0062] In some embodiments, Figure 3 As shown, the sidewall 200 includes a sidewall body 230 and an elastic body 240, the elastic body 240 is sleeved on the outside of the sidewall body 230, the elastic body 240 is an elastic material piece, and one end of the sidewall body 230 is connected to the frame 100. With such a design, the sidewall body 230 provides better support and limiting effects for the sidewall 200, and on this basis, the setting of the elastic body 240 avoids the generation of a splicing seam.

[0063] In this embodiment, the side guard body 230 and the frame body 100 are an integrally formed structure made of the same material. Of course, the side guard body 230 and the frame body 100 can also be made of different materials. Those skilled in the art can select the materials of the side guard body 230 and the frame body 100 according to actual needs, all of which are within the protection scope of this application.

[0064] In some embodiments, reference Figure 3 The thickness of the elastic body 240 at the first end 210 of the rib 200 is greater than the thickness at the second end 220 of the rib 200. With such a design, the rib 200 can have a larger elastic deformation at the first end 210 and can have sufficient supporting force at the second end 220, so that the solar module can fit better with the rib 200 and avoid the appearance of a splicing seam.

[0065] In some embodiments, continue to refer to Figure 3The elastic body 240 extends from the sidewall 200 to cover the outer peripheral surface of the entire frame 100, thereby protecting the entire frame 100. It should be noted that the thickness of the elastic body 240 at the frame 100 is smaller than the thickness of the elastic body 240 at the second end 220 of the sidewall 200, and the thickness of the elastic body 240 at the second end 220 of the sidewall 200 is smaller than the thickness of the elastic body 240 at the first end 210 of the sidewall 200. If the thickness of the elastic body 240 at the frame 100 is too large, the stability of the support of the solar module frame 10 will be affected.

[0066] In some embodiments, Figure 1 As shown, the frame 100 includes a bottom edge 110, a top edge 120, a first supporting edge 130 and a second supporting edge 140. The four edges enclose the frame 100 to form a rectangular structure. The bottom edge 110 and the top edge 120 extend in the horizontal direction, and the first supporting edge 130 and the second supporting edge 140 extend in the vertical direction. The rib 200 is arranged on the top edge 120, and the rib 200 is located on one side of the first supporting edge 130, that is, the rib 200 extends upward from the first supporting edge 130.

[0067] In this embodiment, the bottom edge 110 is equivalent to the base of the entire solar module frame 10, the first supporting edge 130 and the second supporting edge 140 provide more stable support for the top edge 120, the top edge 120 is used to place the solar module, and the retaining edge 200 provides the solar module with limitation and sealing in the x-axis direction.

[0068] In some embodiments, continue to refer to Figure 1 The top edge 120 is provided with a plurality of glue storage grooves 300 which are in the same extension direction as the solar module frame 10, i.e., the z-axis direction. In this embodiment, three glue storage grooves 300 are arranged at intervals on one end of the top edge 120 close to the retaining edge 200.

[0069] Since the solar panel and the solar panel frame 10 need to be bonded and fixed by glue, it is necessary to coat the top edge 120 and the retaining edge 200 with glue, such as silicone. The setting of the glue storage groove 300 is conducive to accommodating the glue, so that the glue fills the entire glue storage groove 300, ensuring a sufficient amount of glue and thus ensuring the stability and sealing effect of the solar panel fixation, and effectively preventing erosion by rainwater.

[0070] In addition, since the glue storage grooves 300 are arranged at intervals, the intervals between adjacent glue storage grooves 300 provide better support for the solar panels; multiple glue storage grooves 300 are arranged on the side of the top edge 120 close to the retaining edge 200, and the side of the top edge 120 away from the retaining edge 200 is a planar structure, which increases the contact area with the solar panels and improves the stability of the support.

[0071] In some embodiments, Figures 1 to 3 As shown, the bottom edge 110 includes an extension portion 1110, and the extension portion 1110 extends horizontally from one end of the bottom edge 110 close to the second supporting edge 140. The provision of the extension portion 1110 increases the contact area between the solar module frame 10 and the ground, and the extension portion 1110 is provided on one side of the second supporting edge 140, that is, the side where the solar module is installed, which improves the stability of the solar module frame 10.

[0072] In some embodiments, after the solar panel is installed on the solar panel frame 10, the length of the side guard 200 is less than the thickness of the solar panel in the vertical direction. It should be noted that the length of the side guard 200 in this embodiment is the total length of the side guard 200 along its edge, not the height of the side guard 200 in the vertical direction in the natural state. Since at least the first end 210 of the side guard 200 in the present application is an elastic material piece, in the natural state without the solar panel installed, the side guard 200 is not completely parallel to the vertical direction, that is, the y-axis direction.

[0073] The length of the rib 200 is set to be smaller than the thickness of the solar module. With this design, after the solar module is installed, the solar module is higher than the rib 200, and there is no step between the upper surface of the solar module and the rib 200, thereby avoiding dust accumulation on the upper surface of the solar module.

[0074] In some embodiments, the side 200 bends toward the frame 100 from the second end 220 to the first end 210 , that is, in the vertical direction, the side 200 bends toward the first supporting edge 130 , and in the horizontal direction, the side 200 bends toward the top edge 120 .

[0075] The design of the rib 200 when the solar module is not installed makes the direction of the elastic restoring force of the rib 200 after elastic deformation be opposite to the installation direction of the solar module after the solar module is installed, so that the rib 200 and the solar module are in close contact, avoiding the generation of a joint. The elastic restoring force here refers to the restoring force generated when an object returns to its original shape or state after deformation.

[0076] In some embodiments, the material of the frame 100 and the main body of the retaining edge 200 is a glass fiber reinforced polyurethane (GRPU) composite material, which has the advantages of high strength, light weight, excellent fire resistance, good dimensional stability, outstanding corrosion resistance, etc. It is easy to transport and improves the stability of the solar module frame 10.

[0077] In some embodiments, the frame 100 and the sidewall 200 are an integrally formed structure manufactured by die pultrusion, thereby ensuring a stable connection between the sidewall 200 and the frame 100.

[0078] In some embodiments, Figure 2 and Figure 3 As shown, the edge of the rib 200 is in an arc shape, and the width of the rib 200 in the x-axis direction gradually decreases from the second end 220 to the first end 210 of the rib 200, which is beneficial to improve the connection and sealing effect with the solar module.

[0079] In some embodiments, a second glue storage groove is provided on the inner wall of the retaining edge 200, that is, the side of the retaining edge 200 close to the second supporting edge 140, and the depth of the second glue storage groove is less than the depth of the glue storage groove 300 on the top edge 120. The second glue storage groove is used to accommodate the bonding glue on the retaining edge 200.

[0080] The method of using the solar panel frame 10 is as follows:

[0081] Adequate adhesive is applied on the top edge 120 of the solar module frame 10, i.e., on the side where the adhesive storage groove 300 is provided, so that the adhesive storage groove 300 is filled with adhesive. A thin layer of adhesive is applied on the inner wall of the rib 200, i.e., on the side of the rib 200 close to the second supporting edge 140. The solar module is placed on the top edge 120 on one side of the second supporting edge 140 and pushed toward the direction of the rib 200, so that the solar module is in sealing contact with the top edge 120 and the rib 200, thereby completing the installation of the solar module.

[0082] The solar module frame 10 provided in the present application avoids the generation of a joint seam between the solar module and the retaining edge 200 by configuring at least the first end portion 210 of the retaining edge 200 as an elastic material piece, and does not need to use a large amount of adhesive for sealing, thereby avoiding the entry of impurities such as rainwater and dust; in addition, the setting of the glue storage groove 300 ensures the sealing of the solar module and the top edge 120; the setting of the extension portion 1110 ensures that the solar module frame 10 will not shake, thereby ensuring power generation efficiency and saving costs.

[0083] In an exemplary embodiment, Figures 4 to 6 As shown, a coating device 400 for making a solar module frame 10 is provided, including a coating cavity 410, a die inlet 420, a die outlet 430, a first baffle 440 and a second baffle 450, wherein the coating cavity 410 is used to fill a coating material, and the semi-solid coating material has a certain viscosity and forms an elastic material piece after cooling to a solid state. The coating material in this embodiment can be selected from thermoplastic materials or thermosetting resin materials with good toughness.

[0084] The die inlet 420 and the die outlet 430 are arranged at both ends of the coating cavity 410 along the z-axis direction and are located in the middle position of the coating cavity 410 in the x-axis direction. The die inlet 420 is arranged at the first end of the coating cavity 410 and is connected with the coating cavity 410. The first substrate 11 enters the coating cavity 410 from the die inlet 420; the die outlet 430 is arranged at the second end of the coating cavity 410 and is connected with the coating cavity 410. The shape of the die outlet 430 is adapted to the shape of the cross section of the solar component frame 10. The die outlet 430 is used to scrape off excess coating material on the surface of the first substrate 11. The adaptation here indicates that the shape of the die outlet 430 is exactly the same as the shape of the cross section of the solar component frame 10, or the shape of the die outlet 430 is slightly larger than the shape of the cross section of the solar component frame 10.

[0085] The first baffle 440 and the second baffle 450 are arranged at both ends of the coating cavity 410 along the z-axis direction, and the planes where the first baffle 440 and the second baffle 450 are located are perpendicular to the z-axis direction. The first baffle 440 is arranged on one side of the die inlet 420, and the second baffle 450 is arranged on one side of the die outlet 430. The opening area of ​​the first baffle 440 is greater than or equal to the area of ​​the die inlet 420 and the opening of the first baffle 440 should completely include the die inlet 420, so that the first substrate 11 enters the coating cavity 410 through the die inlet 420; the opening area of ​​the second baffle 450 is equal to or slightly greater than the area of ​​the die inlet 420 and the opening of the second baffle 450 should completely include the die outlet 430, so that the first substrate 11 passes through the die outlet 430 and passes out of the coating cavity 410.

[0086] The working process of the coating device 400 is as follows:

[0087] When the first substrate 11 passes through the coating cavity 410, the coating material in the coating cavity 410 will adhere to the surface of the first substrate 11. When the first substrate 11 is pulled through the die exit 430, since the die exit 430 has the same cross-section as the solar module frame 10, the die exit 430 can scrape off excess coating material on the surface of the first substrate 11. The first substrate 11 covered with the coating material that leaves the die exit 430 is in the shape of the solar module frame 10.

[0088] Such a design has a simple structure, and the excess coating material scraped off by the die outlet 430 falls back into the coating cavity 410 for recycling, thus saving the cost of raw materials.

[0089] It should be noted that the shape of the die entry 420 can be exactly the same as or different from the shape of the die exit 430. The die entry 420 only needs to ensure that it can limit the first substrate 11 in the x-axis direction and the y-axis direction to prevent the first substrate 11 from shaking during the forward movement and affecting the molding of the solar module frame 10.

[0090] In an exemplary embodiment, the first substrate 11 is Figure 2 The frame 100 shown, or the first substrate 11 is as shown in Figure 3 The frame 100 and the retaining edge 200 shown in the figure constitute an integral structure. The first substrate 11 of both structures can be finally made into a solar module frame 10 comprising at least two materials by a coating device 400.

[0091] In an exemplary embodiment, a plurality of injection ports are provided on the coating cavity 410, and the coating material is injected into the coating cavity 410 through the injection ports. The injection ports are a structure that can be closed and sealed when no injection is required to prevent external impurities from entering the coating cavity 410 through the injection ports and contaminating the coating material.

[0092] In an exemplary embodiment, the coating chamber 410 further includes a heating structure, which is disposed on the inner wall of the coating chamber 410, and is used to heat the coating material. The heating structure is disposed on at least one inner wall of the coating chamber 410 parallel to the z-axis direction. In this embodiment, the heating structure is disposed on four inner walls of the coating chamber 410 parallel to the z-axis direction, thereby ensuring the heating effect, keeping the coating material in a liquid state, and preventing it from solidifying and affecting the coating effect.

[0093] In one embodiment, a temperature sensor is provided in the coating chamber 410, the temperature sensor is electrically connected to the controller, the controller is electrically connected to the heating structure, a target temperature range of the coating material is preset in the controller, the temperature sensor sends the measured temperature in the coating chamber 410 to the controller in real time, when the temperature is lower than the minimum value in the target temperature range, the controller controls the heating structure to start heating the coating material; when the temperature is higher than the maximum value in the target temperature range, the controller controls the heating structure to shut down. Such a design can better ensure the stability of the state of the coating material, and does not require the heating structure to be in the start-up state all the time, saving electric energy.

[0094] In an exemplary embodiment, when the material of the elastomer 240 of the solar module frame 10 is different from the material partially covering the frame body 100, two coating devices 400 are provided, and the coating cavities 410 of the two coating devices 400 are filled with two different coating materials. The two coating devices 400 are arranged successively in the direction in which the first substrate 11 is pulled, and the first substrate 11 is first coated with the first material. The first substrate 11 coated with the first material passes through the first coating device 400 and is cooled and formed, and then passes through the second coating device 400 to be coated with the second material, and finally a solar frame module with two different coating materials is produced.

[0095] In an exemplary embodiment, Figure 7 As shown, a manufacturing process of a solar module frame 10 is provided, comprising the following steps:

[0096] S100 , the first substrate 11 passes through the die inlet 420 into the coating chamber 410 , and then passes through the coating device 400 through the die outlet 430 .

[0097] S200 , inject coating material into the coating cavity 410 through the injection port, and start the heating structure.

[0098] In the above steps, the first substrate 11 is first passed through the coating device 400, and then the coating material is injected into the coating cavity 410 through the injection port. If the order is changed, the hollow part of the first substrate 11 will also be contaminated with the coating material, affecting the quality of the finished product.

[0099] S300 , starting the pulling device so that the pulling device pulls the first substrate 11 from one side of the die outlet 430 .

[0100] In this step, the pulling direction of the pulling device is from the die inlet 420 to the die outlet 430 , and the die outlet 430 is scraped off excess coating material by the pulling of the pulling device.

[0101] S400 , cooling and molding the first substrate 11 that passes through one side of the die outlet 430 and is coated with the coating material to obtain a second substrate.

[0102] In this step, the coating material solidifies at room temperature and becomes solid, and the first substrate 11 coated with the coating material is cooled and formed to obtain a second substrate. If the coating material has other non-normal freezing points, a cooling device can also be provided after the coating device 400 to cool the first substrate 11 coated with the coating material to obtain a second substrate.

[0103] S500 , cutting the second substrate to obtain a solar module frame 10 .

[0105] In one embodiment, the first substrate 11 is a glass fiber composite material, which is manufactured by a pultrusion process. The pultrusion process is a process for producing composite material profiles. It is a method in which continuous fibers or their fabrics are impregnated with resin under the traction of a traction device and the resin is cured by heating a molding die to obtain a finished product. It will not be described in detail here. The first substrate of the glass fiber reinforced polyurethane composite material has the advantages of high strength, light weight, excellent fire resistance, good dimensional stability, excellent corrosion resistance, etc. Of course, those skilled in the art can also select the material and manufacturing method of the first substrate 11 according to actual needs.
