Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and more specifically, to a battery frame and a photovoltaic module. Background Art

[0002] The battery frame is a structure for supporting the battery. Currently, for battery frames, for example, some documents usually use high-temperature resistant polymer materials or metal materials. Although the high-temperature resistant polymer materials have high temperature resistance, their supporting force is poor and they are easily damaged under the action of external forces. While the metal materials have good supporting force, but their insulation performance is poor and potential safety hazards are likely to occur. Summary of the Utility Model

[0003] The utility model aims to solve or improve the technical problem that the related battery frames cannot ensure both the supporting strength and the insulation performance at the same time.

[0004] The first aspect of the utility model is to provide a battery frame.

[0005] The second aspect of the utility model is to provide a photovoltaic module.

[0006] The battery frame provided by the utility model includes: a first plate; a second plate connected to the first plate, and both the first plate and the second plate are glass fiber-resin composite plates; a metal support structure disposed between the first plate and the second plate for supporting the first plate and the second plate.

[0007] For the battery frame provided by the utility model, the glass fiber-resin composite plate has good heat resistance and insulation performance. Then, by using the metal support structure to support the first plate and the second plate, it can make up for the deficiency of the supporting strength of the polymer material frame. Compared with the frame made of metal plates, it also has good insulation performance, ensuring both the supporting strength and the heat resistance and insulation performance.

[0008] In some technical solutions, optionally, the battery frame further includes a first groove provided on the surface of the first plate close to the second plate, and the metal support structure is disposed in the first groove.

[0009] In this technical solution, by providing a first groove on the surface of the first plate close to the second plate and then disposing the metal support structure in the first groove, the metal support structure can be well fixed, and at the same time, the metal support structure can be completely hidden inside the battery frame, improving the overall aesthetics.

[0010] In some technical solutions, optionally, the battery frame further includes a second groove provided on the surface of the second plate close to the first plate, the second groove corresponds to the first groove, and the metal support structure is disposed in the first groove and the second groove.

[0011] In this technical solution, a second groove is provided on the surface of the second plate close to the first plate. The metal support structure is accommodated jointly by the first groove and the second groove, which can increase the thickness of the metal support structure, thereby expanding the support strength of the battery frame.

[0012] In some technical solutions, optionally, the metal support structure is a metal plate, and the thickness of the metal plate is equal to twice the depth of the first groove and equal to twice the depth of the second groove.

[0013] In this technical solution, the first plate and the second plate have grooves with the same depth, that is, the first plate and the second plate are the same plate. This reduces the number of preparation molds during the preparation process and has higher preparation efficiency. The thickness of the metal plate is equal to twice the depth of the first groove, which can ensure that the metal plate is exactly placed in the first groove and the second groove, with good stability. Of course, considering errors, the thickness of the metal plate can also be slightly less than twice the depth of the first groove, for example, less than 1 mm.

[0014] In some technical solutions, optionally, the first plate and the second plate are integrally formed hollow plates, and the metal support structure is arranged in the hollow cavity of the hollow plates.

[0015] In this technical solution, the first plate and the second plate are integrally formed hollow plates, so there is no need to additionally weld and engage structures on the first plate and the second plate, etc., to achieve the assembly of the first plate and the second plate. In addition, compared with the clamping method, the connection strength between the first plate and the second plate is better.

[0016] In some technical solutions, optionally, the battery frame further includes a plugging member, which is arranged at both ends of the hollow plate along the extending direction of the hollow cavity for covering the hollow cavity.

[0017] In this technical solution, plugging members are arranged at both ends of the hollow plate, which can seal the hollow cavity, thereby sealing the metal support structure inside the hollow cavity, improving the overall aesthetics, and the metal support structure is not easily detached. Optionally, the plugging member is made of an insulating material.

[0018] In some technical solutions, optionally, connection lugs are provided on the first plate and the second plate, and the first plate and the second plate can be connected through the connection lugs.

[0019] In this technical solution, when the first plate and the second plate are not integrally formed, the first plate and the second plate can be connected through the connection lugs to achieve rapid disassembly.

[0020] In some technical solutions, optionally, the metal support structure includes one or a combination of the following: aluminum alloy strip, aluminum strip, and aluminum mesh.

[0021] In this technical solution, the aluminum alloy strip, the aluminum strip, and the aluminum mesh all have good support strength, so that the battery frame will not easily deform under the action of external forces.

[0022] In some technical solutions, optionally, the glass fiber-resin composite board includes one or a combination of the following: glass fiber-epoxy resin composite board, glass fiber-polyester resin composite board, and glass fiber-phenolic resin composite board.

[0023] In this technical solution, the glass fiber has the characteristics of good molding, small bulk density, low thermal conductivity, heat preservation and insulation, good sound absorption performance, corrosion resistance, stable chemical properties, etc., and the resin also has advantages such as heat resistance and insulation, thus improving the heat resistance and insulation of the battery frame. Among them, the contents of the glass fiber and the resin can be adjusted according to different requirements. For example, the proportion of the glass fiber is 25% to 40%, and the rest is resin. It is also possible that the resin proportion is between 25% and 35%, and the rest is glass fiber.

[0024] In some technical solutions, optionally, the metal support structure is a metal plate, and the thickness of the metal plate is greater than or equal to 0.1 mm and less than or equal to 5 mm.

[0025] In this technical solution, if the thickness of the metal plate is too thin, the support strength will be reduced, and if the thickness is too thick, the thickness of the frame will increase, and the improvement effect is not obvious. Therefore, it is most suitable to be set between 0.1 mm and 5 mm. Optionally, the thickness of the metal plate is 1 mm to 5 mm, such as 2 mm and 3 mm.

[0026] In some technical solutions, optionally, the sum of the thicknesses of the first plate and the second plate is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0027] In this technical solution, if the total thickness of the first plate and the second plate is too thick, the thickness of the product will increase, which is not conducive to small models. If it is too thin, the insulation and heat insulation effects will be reduced. Therefore, it is most suitable to be set between 0.5 mm and 5 mm. Optionally, the total thickness is 1 mm to 5 mm, such as 3 mm and 4 mm.

[0053] In order to be able to more clearly understand the above aspects, features and advantages of the embodiments according to the present invention, the embodiments according to the present invention will be further described in detail below with reference to the drawings and specific implementation modes. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to fully understand the embodiments according to the present invention. However, the embodiments according to the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the embodiments according to the present invention is not limited by the specific embodiments disclosed below.

[0055] The battery frame 1 provided in this embodiment includes a first plate 101, a second plate 102 and a metal support structure 12. The second plate 102 is connected to the first plate 101. Both the first plate 101 and the second plate 102 are glass fiber - resin composite plates. The metal support structure 12 is disposed between the first plate 101 and the second plate 102 and is used to support the first plate 101 and the second plate 102.

[0056] More specifically, as Figure 1 and Figure 4 shown, the battery frame 1 is enclosed by a frame plate 10 and a connection plate 11. The frame plate 10 includes a first plate 101, a second plate 102 and a metal support structure 12. The metal support structure 12 is disposed between the first plate 101 and the second plate 102. For the battery frame 1 provided by the present invention, the glass fiber - resin composite plate has good heat resistance and insulation performance. Then, the first plate 101 and the second plate 102 are supported by the metal support structure 12, which can make up for the insufficient frame support strength of the polymer material. Compared with the frame of the metal plate, it also has good insulation performance, ensuring both the support strength and the heat resistance and insulation performance.

[0057] In some technical solutions, optionally, as Figure 1 shown, the battery frame 1 further includes a first groove 1012, which is disposed on the surface of the first plate 101 close to the second plate 102, and the metal support structure 12 is disposed in the first groove 1012.

[0058] In this technical solution, by providing a first groove 1012 on the surface of the first plate 101 close to the second plate 102, and then disposing the metal support structure 12 in the first groove 1012, the metal support structure 12 can be well fixed, and at the same time, the metal support structure 12 can be completely hidden inside the battery frame 1, improving the overall aesthetic appearance.

[0059] In some technical solutions, optionally, as Figure 1 shown, the battery frame 1 further includes a second groove 1022 provided on the surface of the second plate 102 close to the first plate 101. The second groove 1022 is provided corresponding to the first groove 1012, and the metal support structure 12 is disposed in the first groove 1012 and the second groove 1022.

[0060] In this technical solution, a second groove 1022 is provided on the surface of the second plate 102 close to the first plate 101. By jointly accommodating the metal support structure 12 in the first groove 1012 and the second groove 1022, the thickness of the metal support structure 12 can be increased, thereby expanding the support strength of the battery frame 1.

[0061] In some technical solutions, optionally, the metal support structure 12 is a metal plate, and the thickness of the metal plate is equal to twice the depth of the first groove 1012 and equal to twice the depth of the second groove 1022.

[0062] In this technical solution, the first plate 101 and the second plate 102 have grooves with the same depth, that is, the first plate 101 and the second plate 102 are the same plate, so the number of preparation molds can be reduced during the preparation process, and the preparation efficiency is higher. The thickness of the metal plate is equal to twice the depth of the first groove 1012, which can ensure that the metal plate is exactly placed in the first groove 1012 and the second groove 1022, with good stability. Of course, considering errors, the thickness of the metal plate can also be slightly less than twice the depth of the first groove 1012, for example, less than 1 mm.

[0063] In some technical solutions, optionally, as Figure 6 shown, the first plate 101 and the second plate 102 are integrally formed hollow plates 13, and the metal support structure 12 is disposed in the hollow cavity 132 of the hollow plate 13.

[0064] In this technical solution, the first plate 101 and the second plate 102 are integrally formed hollow plates 13, so there is no need to additionally weld and engage structures on the first plate 101 and the second plate 102 to achieve the assembly of the first plate 101 and the second plate 102. In addition, compared with the clamping method, the connection strength between the first plate 101 and the second plate 102 is better.

[0065] In some technical solutions, optionally, as Figure 6As shown, the battery frame 1 further includes a plugging member 14, which is disposed at both ends of the hollow plate 13 along the extending direction of the hollow cavity 132 for covering the hollow cavity 132.

[0066] In this technical solution, the plugging member 14 is provided at both ends of the hollow plate 13, so that the hollow cavity 132 can be sealed, thereby sealing the metal support structure 12 inside the hollow cavity 132, improving the overall aesthetics, and the metal support structure 12 is not easily detached. Optionally, the plugging member 14 is made of an insulating material.

[0067] In some technical solutions, optionally, as Figure 1 and Figure 3 shown, connecting ears 15 are provided on the first plate 101 and the second plate 102, and the first plate 101 and the second plate 102 can be connected through the connecting ears 15.

[0068] In this technical solution, when the first plate 101 and the second plate 102 are not integrally formed, the first plate 101 and the second plate 102 can be connected through the connecting ears 15 to achieve rapid disassembly.

[0069] In some technical solutions, optionally, as Figure 2 shown, the metal support structure 12 includes one or a combination of the following: an aluminum alloy strip, an aluminum strip, and an aluminum mesh.

[0070] In this technical solution, the aluminum alloy strip, the aluminum strip, and the aluminum mesh all have good support strength, so that the battery frame 1 will not easily deform under the action of external forces.

[0071] In some technical solutions, optionally, the glass fiber - resin composite plate includes one or a combination of the following: a glass fiber - epoxy resin composite plate, a glass fiber - polyester resin composite plate, and a glass fiber - phenolic resin composite plate.

[0072] In this technical solution, the glass fiber has the characteristics of good molding, small volume density, low thermal conductivity, heat preservation and insulation, good sound absorption performance, corrosion resistance, stable chemical properties, etc., and the resin also has advantages such as heat resistance and insulation, thereby improving the heat resistance and insulation of the battery frame 1. Among them, the contents of the glass fiber and the resin can be adjusted according to different requirements. For example, the glass fiber accounts for 25% to 40%, and the rest is resin. It is also possible that the resin proportion is between 25% and 35%, and the rest is glass fiber.

[0073] In some technical solutions, optionally, the metal support structure 12 is a metal plate, and the thickness of the metal plate is greater than or equal to 0.1 mm and less than or equal to 5 mm.

[0074] In this technical solution, if the thickness of the metal plate is too thin, the support strength will be reduced. If the thickness is too thick, the thickness of the frame will increase, and the improvement effect will not be obvious. Therefore, it is most suitable to be set between 0.1 mm and 5 mm. Optionally, the thickness of the metal plate is 1 mm to 5 mm, such as 2 mm and 3 mm.

[0075] In some technical solutions, optionally, the sum of the thicknesses of the first plate 101 and the second plate 102 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0076] In this technical solution, if the total thickness of the first plate 101 and the second plate 102 is too thick, the thickness of the product will increase, which is not conducive to small models. If it is too thin, the insulation and heat insulation effects will be reduced. Therefore, it is most suitable to be set between 0.5 mm and 5 mm. Optionally, the total thickness is 1 mm to 5 mm, such as 3 mm and 4 mm.

[0077] As Figure 5 shown, in the second aspect of the present utility model, a photovoltaic module 2 is provided, including: the battery frame 1 provided in any one of the embodiments of the first aspect of the present utility model. Since the photovoltaic module 2 provided by the present utility model includes the battery frame 1 provided in any one of the embodiments of the first aspect of the present utility model, therefore, it has all the beneficial effects of the battery frame 1 provided in any one of the embodiments of the first aspect of the present utility model.

EPE can effectively protect the photovoltaic module 2 from impact and vibration, improving the reliability of the photovoltaic module 2. In addition, the heat insulation performance of EPE can effectively reduce the temperature of the photovoltaic module 2 and improve the power generation efficiency of the photovoltaic module 2.

[0091] In this embodiment, both the EVA layer and the POE layer have good connection performance, improving the overall stability of the photovoltaic module 2.

[0092] Another embodiment of the present utility model provides a battery frame 1.

[0093] First of all, it should be understood that related single-sided portable photovoltaic modules usually use a fiberglass board encapsulated inside the product as the support structure of the battery. However, this traditional process has some limitations, such as it is difficult to achieve double-sided power generation, and the use of glass materials makes the product too heavy, which is not conducive to folding and carrying. To solve these problems, some technologies attempt to change the fiberglass board design to a fiberglass frame design to achieve double-sided power generation of the module. However, this design change has changed the force support method, from surface support to line support, and the support area has decreased, resulting in the photovoltaic module being prone to thermal deformation when heated. Moreover, the mechanical strength of the fiberglass board used is generally low, which limits its use in application scenarios that require high mechanical strength and stability.

[0094] The present utility model provides a battery frame 1, and its technical solution is as follows:

[0095] As Figure 1 shown, the battery frame 1 includes a fiberglass board, which is composed of a first board 101 and a second board 102. The fiberglass board is a new type of composite board formed by compounding glass fibers and resin. Its main component is glass fiber, and this fiber is formed by fibrillating molten glass, having characteristics such as good forming, small volume density, low thermal conductivity, heat preservation and insulation, good sound absorption performance, corrosion resistance, and stable chemical properties. Among them, the content of glass fiber is 25% to 40%, and the rest is resin. Of course, it can also be that the content of resin is between 25% and 35%, and the rest is glass fiber.

[0096] In addition, a groove is opened inside the fiberglass board, and then a metal strip with a fixed size is pressed into the groove. In the present utility model, a groove is opened on the fiberglass board, and the metal strip or metal mesh is placed in the groove to form a tight contact area, improving the mechanical strength and stability of the photovoltaic module 2.

[0097] In addition, the first board 101 and the first groove 1012 correspond to the second board 102 and the second groove 1022, and the metal strip is placed in the groove.

[0098] In addition, the depth of the groove in the first board 101 and the second board 102 is 1 / 2 of the thickness of the metal strip.

[0099] In addition, the thickness range of the fiberglass board is 0.5 mm to 5 mm.

[0100] In addition, the thickness of the metal strip or metal mesh is adjusted according to the thickness of the fiberglass board, and the range is 0.1 mm to 5 mm.

[0101] In addition, the metal strip or metal mesh is placed in the middle layer of the groove of the fiberglass board and cannot be exposed outside, but is completely hidden inside the fiberglass board.

[0102] The beneficial effects of the battery frame 1 of the present utility model are as follows:

[0103] 1. By adding a metal strip inside the fiberglass board, the mechanical strength of the photovoltaic module 2 is effectively increased, and the problem of thermal deformation of the module is alleviated.

[0104] 2. The present utility model improves the long-term use performance of the portable photovoltaic module 2, making it more suitable for various application scenarios, especially in environments that require high mechanical strength and stability.

[0105] In an embodiment according to the present utility model, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; the term "plurality" means two or more, unless otherwise clearly defined. Terms such as "installed", "connected", "connected to", and "fixed" should all be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments according to the present utility model can be understood according to specific circumstances.

[0106] In addition, although the operations are depicted in a particular order, this should be understood as requiring such operations to be performed in the particular order shown or in a sequential order, or requiring all of the illustrated operations to be performed to achieve the desired result. In certain environments, multitasking and parallel processing may be advantageous.
