Description

Technical Field

[0001] The utility model relates to the field of photovoltaic modules, in particular to an elastic protective member for a photovoltaic module frame. Background Art

[0002] The elastic protective members used in photovoltaic module frames are materials designed to enhance module durability and safety. Their primary functions include cushioning, shock absorption, scratch protection, and waterproofing. During transportation, installation, and daily use, these protective members effectively reduce damage to photovoltaic panels caused by external impacts, prevent moisture intrusion, and extend module life. Proper application of these protective members can enhance the stability and aesthetics of the entire solar system.

[0003] Chinese utility model patent CN209748480U discloses an elastic protective member for a photovoltaic module frame, a photovoltaic module frame, and a photovoltaic module. The elastic protective member in the patent is formed into a U-shaped body. The U-shaped body of the elastic protective member avoids hard contact between the laminate in the photovoltaic module including the elastic protective member and the photovoltaic module frame, thereby increasing the load capacity of the photovoltaic module. However, in actual applications, the elastic protective member still has some shortcomings. Due to long-term exposure to harsh conditions such as outdoor ultraviolet rays and extreme temperature changes, these elastic materials are prone to aging, resulting in a decrease in their buffering performance and even loss of their original waterproof sealing effect, so they need to be replaced regularly. However, in the design of this patent, the number and installation position of the elastic protective members are fixed, which brings inconvenience to disassembly and assembly. In particular, when maintaining or replacing photovoltaic panels, it is often necessary to replace the frame as a whole, and the operation process is cumbersome and time-consuming.

[0019] The present invention provides an elastic protective member for a photovoltaic module frame. Figure 1-Figure 5 As shown, it includes a frame 1 with a sliding cavity 11 opened inside, and a clamping pad 2 slidably set in the sliding cavity 11 of the frame 1. The clamping pad 2 is provided with anti-slip grooves, which can clamp and limit the photovoltaic module more stably, and the number of the clamping pads 2 can be increased or decreased according to specific needs, such as Figure 2 As shown, in the embodiment of the present invention, two clamping pads 2 are provided in each frame 1, and since the clamping pads 2 are slidingly provided, they can be easily disassembled and replaced after aging.

[0020] like Figure 1 、 Figure 2 and Figure 4 As shown, in the embodiment of the present utility model, the left side wall of the frame 1 (with Figure 1 Two guide rods 3 are symmetrically arranged on the upper side and slide through the upper side, and the right ends of the two guide rods 3 extend into the sliding cavity 11. Figure 2 As shown, a limit pad 31 is provided in the sliding cavity 11. Figure 4 As shown, the left side wall of the limiting pad 31 (with Figure 4 The right end of the two guide rods 3 is fixedly connected to each other, and the left side wall of the limit pad 31 is provided with a screw 32. Figure 1 As shown, the screw 32 rotates and penetrates the left side wall of the frame 1. The right side wall of the limiting pad 31 is provided with anti-slip grooves. After the clamping pad 2 clamps and fixes the photovoltaic module, when the screw 32 is turned clockwise, the right side wall of the limiting pad 31 can approach and abut the clamping pad 2, thereby limiting the position of the clamping pad 2 and preventing it from moving freely, thereby improving the stability of the clamping of the photovoltaic module.

[0021] like Figure 1As shown, in the embodiment of the present invention, a clamping cavity 12 is further provided at the lower part of the frame 1, and the clamping cavity 12 can be used to clamp the frame 1 to a bracket or other support, and a waist-shaped hole 121 is provided at the bottom of the frame 1. The screws are passed through the waist-shaped hole 121 and nailed to the support, which can further fix the position of the frame 1, thereby improving the installation stability of the photovoltaic module.

[0022] like Figure 1-Figure 3 As shown, in the embodiment of the present invention, two guide folding frames 4 are symmetrically fixed at the top of the frame 1. An N-shaped insertion rod 41 is slidably connected between the two guide folding frames 4. An elastic member 42 is provided between the insertion rod 41 and the guide folding frames 4. The elastic member 42 is a spring. Under the action of the elastic member 42, the bottom of the insertion rod 41 passes through the top of the frame 1 and extends into the frame 1. A wedge block 411 is provided on the portion of the insertion rod 41 that extends into the frame 1. Under the obstruction of the wedge block 411, the clamping pad 2 located in the frame 1 cannot slide out unless the insertion rod 41 is pulled upward, which further improves the stability of the photovoltaic module after installation. The wedge block 411 is provided with an inclined surface. When it is necessary to install the clamping pad 2 into the frame 1, the clamping pad 2 only needs to be pushed into the frame 1. The clamping pad 2 will then be pushed upward along the inclined surface of the wedge block 411, and the clamping pad 2 can be smoothly inserted into the frame 1 without manually pulling out the insertion rod 41, thereby improving the convenience of operation.

[0023] like Figure 5 As shown, both ends of the frame 1 are respectively provided with matching docking sleeves 5 and docking rotating rods 51. The two adjacent frames 1 can be connected in series through the snap-fit cooperation between the docking sleeves 5 and the docking rotating rods 51, and the number of frames 1 can be increased or decreased according to the specific size of the photovoltaic module.
