Description

Technical Field

[0001] This application relates to the technical field of solar photovoltaics, and more specifically, it relates to a flexible protective frame for a flexible solar panel. Background Art

[0002] The protective frame of a solar panel is used to protect the solar panel from damage by the external environment and provide support and fixation. The existing protective frames of solar panels are generally assembled from aluminum alloy profiles. The aluminum alloy profiles have a cavity structure, and the installation method is that the edge of the solar panel is inserted into the cavity structure to obtain support. However, for a flexible solar panel, using an aluminum alloy profile as the protective frame, the aluminum alloy profile is a hard material, which will cause the flexible solar panel to lose its flexible characteristics and cannot be adaptively bent and attached to a curved surface for installation. Therefore, it is necessary to propose a flexible protective frame to meet the protection requirements of flexible solar panels. Utility Model Content

[0003] In order to solve the problem that using an aluminum alloy profile as the protective frame will cause the flexible solar panel to lose its flexible characteristics and cannot be adaptively bent and attached to a curved surface for installation, this application provides a flexible protective frame for a flexible solar panel.

[0004] A flexible protective frame for a flexible solar panel includes an integrally formed frame body. The frame body is made of a flexible material and has sufficient flexibility. A groove is recessed on the inner peripheral side of the frame body for accommodating the edge of the solar panel and providing support. The frame body is provided with a slot, and the slot communicates with the groove for inserting the flexible solar panel into the frame body.

[0005] It also includes a sealing strip and two first snap buttons. On the outer peripheral side of the frame body, a receiving groove is recessed at the edge of the slot. First mounting grooves are recessed on the inner walls at both ends of the receiving groove. The bodies of the two first snap buttons are respectively fixed in the first mounting grooves, and the locks of the two first snap buttons are respectively fixed at both ends of the sealing strip. The sealing strip is detachably mounted in the receiving groove through the first snap buttons to close the slot, and the material of the sealing strip is the same flexible material as the frame body.

[0006] Preferably, it further includes a plurality of second snap buttons. A plurality of second mounting grooves are recessed on the lower inner wall of the groove, and the body of a second snap button is fixed in each second mounting groove. The locks of the plurality of second snap buttons are fixed on the upper inner wall of the groove.

[0007] Preferably, the material of the frame body is one of polyethylene, polypropylene, polyvinyl chloride, and rubber materials.

[0008] Preferably, the thickness of the frame body is 0.5 cm - 2 cm.

[0009] Preferably, a plurality of convex grains are convexly provided at intervals on the bottom surface of the frame body.

[0010] Preferably, the convex height of the convex grains is 0.1 - 0.2 cm.

[0011] In summary, the present application includes at least one of the following beneficial technical effects:

[0012] 1. The flexible solar panel is inserted into the groove of the frame body, and the frame body wraps the edge of the flexible solar panel, realizing the protection of the flexible solar panel by the frame body and reducing the damage of the solar panel caused by the external environment. The frame body is made of flexible material and has sufficient flexibility, which is conducive to bending the frame body and adaptively attaching it to the curved surface with the solar panel. The solar panel is conveniently installed in the frame body through the slot communicated with the groove, and the slot is closed by the sealing strip and detachably connected to the frame body through the first button buckle, realizing the limit of the solar panel from detaching from the slot and reducing the damage of the solar panel caused by the external environment acting on the solar panel through the slot.

[0013] 2. The edge of the flexible solar panel is provided with a communication hole that matches the lock of the second button buckle. When the flexible solar panel is installed in the groove, each communication hole is aligned with a second button buckle. By pressing the part of the frame body where the second button buckle is located, the lock of the second button buckle passes through the connection hole provided at the edge of the flexible solar panel and is snapped into the buckle body of the second button buckle, realizing the limit of the flexible solar panel and restricting the flexible solar panel from detaching from the groove when bending. Further, the upper and lower inner walls of the groove are closely attached to the flexible solar panel through the buckling of the lock and the buckle body of the second button buckle, and the waterproof effect is better.

[0014] 3. When the flexible solar panel is applied to an automobile, it is usually attached and fixed on the top of the automobile. The roof is the main area exposed to the sun, and the temperature on it is relatively high, which easily leads to a decline in the performance of the solar panel. When the flexible solar panel and the frame are installed, the convex grains are in contact with the top of the automobile for support, so that there is a gap for air flow between the flexible solar panel and the frame and the top of the automobile. Through the continuous flow of air through this gap, the heat on the top of the automobile is not easily accumulated at the solar panel, realizing better heat dissipation of the flexible solar panel.

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0020] Embodiment 1

[0021] A flexible protective frame for a flexible solar panel, comprising a housing 1, a sealing strip 2, and a first button buckle 3. The housing 1 is made of a flexible material and has sufficient flexibility. The flexible material can be one of polyethylene, polypropylene, polyvinyl chloride, and rubber materials. In this embodiment, rubber material is used. The housing 1 is rectangularly arranged with four side strips. A groove 11 is recessed on the inner peripheral side of the housing 1. A slot 12 communicating with the groove 11 is opened on one side strip of the housing 1. The flexible solar panel is inserted into the groove 11 through the slot 12. The flexible solar panel is supported and the housing 1 wraps the edge of the flexible solar panel to protect the flexible solar panel from being damaged by the external environment. The material of the sealing strip 2 is the same flexible material as that of the housing 1. A receiving groove 13 is recessed on the outer peripheral side of the housing 1 at the edge of the slot 12. First mounting grooves 14 are recessed on the inner walls at both ends of the receiving groove 13. The buckle bodies of the two first buttons are respectively fixed in the first mounting grooves 14, and the fixing method is by glue. The lock heads of the two first button buckles 3 are respectively fixed at both ends of the sealing strip 2, and the fixing method is also by glue. The sealing strip 2 is installed in the receiving groove 13 by pressing the lock head of the first button buckle 3 into the buckle body of the first button opening, so as to fix the housing 1 and the sealing strip 2. The size of the sealing strip 2 matches the size of the receiving groove 13. When the sealing strip 2 is inserted into the receiving groove 13, the outer wall fits with the inner wall of the receiving groove 13, so as to seal the slot 12, limit the flexible solar panel from detaching from the housing 1 through the slot 12, and has a good waterproof effect. The flexible housing 1 and the sealing strip 2 are easy to bend, so that the housing 1 can be bent and adaptively attached to the curved surface for installation with the solar panel.

[0022] The thickness of the frame body 1 is 0.5 cm - 2 cm. Within this thickness range, the frame body 1 has good support and flexibility. While protecting the flexible solar panel, it can be bent to a large extent to adapt to the installation environment. In this embodiment, the thickness of the frame body 1 is 1 cm. In this embodiment, the width of the groove 11 is slightly smaller than the thickness of the edge of the flexible solar panel, so as to press the flexible solar panel tightly and have a good wrapping effect on the edge.

[0023] The lock head of the first button fastener 3 is cylindrical. There are tiny protrusions on the outer wall of the top of the cylindrical fastener body. The fastener body of the first button fastener 3 has an inner hole with an inner diameter slightly larger than the diameter of the lock head. There is a card slot on the inner hole wall for engaging the protrusion. When the lock head is pressed into the inner hole of the fastener body, the protrusion is snapped into the card slot to fix the frame body 1 and the sealing strip 2. By pulling the sealing strip 2 forcefully, the lock head can be pulled out of the inner hole of the fastener body, which is convenient for disassembling the sealing strip 2. The sealing strip 2 and the frame body 1 are detachably installed, which is convenient for disassembling and repairing the flexible solar panel.

[0024] Embodiment 2

[0025] The difference between Embodiment 2 and Embodiment 1 is as follows: A flexible protective frame for a flexible solar panel further includes eight second button fasteners 4. There are eight second installation slots 15 recessed on the lower inner wall of the groove 11. There are two spaced second installation slots 15 on each side strip. The fastener body of each second button fastener 4 is fixed in each second installation slot 15 by glue. The lock heads of the eight second button fasteners 4 are fixed on the upper inner wall of the groove 11 by glue. The lock heads are aligned with the fastener bodies. The lock heads and fastener bodies of the second button fasteners 4 are of the same shape as those of the second button fasteners 4. In this embodiment, the width of the groove 11 is slightly larger than the thickness of the edge of the flexible solar panel to achieve the installation avoidance of the lock heads of the second button fasteners 4 and the flexible solar panel.

[0026] Communication holes matching the lock heads of the second button fasteners 4 are provided at the edges of the four sides of the flexible solar panel. When installing the flexible solar panel into the groove 11, each communication hole is aligned with a second button fastener 4. By pressing the part of the second button fastener 4 on the frame body 1, the lock head of the second button fastener 4 is passed through the connection hole provided at the edge of the flexible solar panel and then snapped into the fastener body of the second button to limit the flexible solar panel and prevent it from disengaging from the groove 11 when being bent. Further, by the snap fit of the lock head and fastener body of the second button fastener 4, the upper and lower inner walls of the groove 11 are closely attached to the flexible solar panel, and the waterproof effect is better.

[0027] Embodiment 3

[0028] The difference between Embodiment 3 and Embodiment 1 is that: several convex grains 16 are convexly provided at intervals on the bottom surface of the frame body 1, and the convex height of the convex grains 16 is 0.1 - 0.2 cm, which is 0.2 cm in this embodiment. When the flexible solar panel is applied to an automobile, it is usually attached and fixed to the top of the automobile. The roof is the main area exposed to the sun, and the temperature on it is relatively high, which easily causes the performance of the solar panel to decline. When the flexible solar panel and the frame are installed, they are supported by contacting the top of the automobile through the convex grains 16, so that there is a gap for air flow between the flexible solar panel and the frame and the top of the automobile. Through the continuous flow of air through this gap, the heat on the top of the automobile is not easily accumulated at the solar panel, realizing better heat dissipation of the flexible solar panel.

[0029] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
