[0039] See Figure 1 and Figure 2 This utility model provides a reliability testing bracket for a photovoltaic module 300. The photovoltaic module 300 reliability testing bracket includes a frame 100 and a fixing component 200. The frame 100 is constructed as a hollow structure and has an accommodating cavity with at least one open end for accommodating the photovoltaic module 300. The fixing component 200 is fixedly connected to the frame 100 and has a clamping recess. The clamping opening size of the clamping recess is adjustable and is used to clamp the photovoltaic module 300.
[0040] This invention provides a reliability testing bracket for a photovoltaic module 300, with a frame 100 supporting the photovoltaic module 300. The frame 100 is constructed with a hollow structure to ensure stable impact circulation of air onto the photovoltaic module 300 during testing. A receiving cavity with at least one open end is provided on the frame 100 to allow the photovoltaic module 300 to be placed into the cavity through the opening. A fixing component 200 with a clamping notch is provided on the frame 100 to clamp the photovoltaic module 300, thus fixing it within the receiving cavity. This structure ensures the photovoltaic module 300 is securely fixed within the frame 100, preventing it from shaking when impacted by air from the external environment, thereby reducing wear on the photovoltaic module 300.
[0041] like Figure 1 and Figure 2 As shown, specifically, the fixing assembly 200 includes an outer frame 210, grippers 220, guide rods 230, and elastic members 240. The outer frame 210 has a mounting groove and is fixedly connected to the frame 100. Two grippers 220 are disposed in the mounting groove, and a clamping notch is defined between the two grippers 220. A plurality of guide rods 230 are spaced apart along the extending direction of the grippers 220. One end of each guide rod 230 is fixedly connected to the gripper 220, and the other end is movably connected to the outer frame 210. The elastic member 240 is sleeved on the guide rod 230 and is pressed between the outer frame 210 and the grippers 220.
[0042] like Figure 2 As shown, the mounting groove is used to install the grippers 220, guide rods 230, and springs, etc., and to fix the outer frame 210 to the frame 100 so that the grippers 220, guide rods 230, and springs are all connected to the frame 100. Two opposing grippers 220 are arranged in the mounting groove, so that the gap between the two grippers 220 forms a clamping recess. The two grippers 220 apply force to the photovoltaic module 300 to clamp it. Multiple spaced guide rods 230 are arranged in the extending direction of the grippers 220, with one end of each guide rod 230 fixed to the gripper 220 and the other end movably connected to the outer frame 210. This allows the grippers 220 to move relative to the outer frame 210, thereby adjusting the distance between the two grippers 220 and enabling the clamping and unclamping of the photovoltaic module 300. By fitting an elastic element 240 onto the guide rod 230 and pressing the elastic element 240 between the outer frame 210 and the gripper 220, the elastic force of the elastic element 240 is used to apply a pushing force to the gripper 220, thereby clamping the photovoltaic module 300.
[0043] like Figure 2 As shown, in this embodiment, the outer frame 210 is constructed as a U-shaped component, and the U-shaped groove of the U-shaped component is the mounting recess. The gripper 220 can be configured as a flat rectangular structure, with the larger flat surface of the gripper 220 used to clamp the photovoltaic module 300. The guide rod 230 can be configured as a square rod or a round rod. The elastic element 240 is a spring, which is sleeved on the outside of the guide rod 230, with its two ends abutting against the outer frame 210 and the gripper 220 respectively. When it is necessary to clamp the photovoltaic module 300, an external force is applied to the gripper 220, causing the gripper 220 to move towards the side wall of the outer frame 210. At this time, the spring is further compressed, and the distance between the two grippers 220 increases, so that the photovoltaic module 300 can be locked in the clamping recess. Once the photovoltaic module 300 is inserted into the clamping notch, the force applied to the clamp 220 can be released. Under the restoring force of the spring, the clamp 220 moves towards the photovoltaic module 300, and the two clamps 220 clamp the photovoltaic module 300 tightly.
[0044] Furthermore, the fixing component 200 is welded to the frame 100. Specifically, the outer frame 210 is fixed to the frame 100 by welding. Fixing the outer frame 210 to the frame 100 by welding reduces the number of parts and ensures stable and reliable fixation. Of course, in other embodiments, the outer frame 210 can also be fixed to the frame 100 by bolts.
[0045] In one embodiment, a guide hole is formed on the outer frame 210, and the end of the guide rod 230 facing away from the gripper 220 passes through the guide hole. A limiting member is connected to the end of the guide rod 230 facing away from the gripper 220 to limit the travel of the guide rod 230. By providing a guide hole on the outer frame 210, passing the end of the guide rod 230 facing away from the gripper 220 through the guide hole, and connecting a limiting member at the end, when the guide rod 230 moves along the guide hole with the gripper 220 under the spring's restoring force, when the guide rod 230 moves to abut against the limiting member and the outer frame 210, the outer frame 210 and the limiting member abut against each other, and the guide rod 230 stops moving.
[0046] The specific shape of the guide hole is adapted to the guide rod 230. When the guide rod 230 is set as a square rod, the guide hole is a square hole; when the guide rod 230 is set as a round rod, the guide hole is a round hole. In this embodiment, the limiting components are a nut and a washer. There is no limitation on the number of guide rods 230 corresponding to one gripper 220; there can be two or three. In this embodiment, three guide rods 230 are arranged at intervals along the length direction of the gripper 220, and correspondingly, three guide holes are provided on one side wall of the outer frame 210.
[0047] like Figure 2 As shown, in one embodiment, the gripper 220 includes a gripping portion 221 and a guiding portion 222. The surface of the gripping portion 221 used to grip the photovoltaic module 300 is configured as a plane; the side of the guiding portion 222 away from the outer frame 210 is configured as an arc surface. The distance between the opposite sides of the guiding portions 222 of the two grippers 220 gradually increases from the end closer to the gripping portion 221 to the end farther away from the gripping portion 221.
[0048] The clamping part 221 is used to clamp the photovoltaic module 300. The surface of the clamping part 221 used to clamp the photovoltaic module 300 is set as a plane to increase the contact area between the clamping part 221 and the photovoltaic module 300, thereby ensuring the reliability of clamping the photovoltaic module 300. The guide is used to guide the photovoltaic module 300 into the clamping recess before it is inserted into the clamping recess, thereby facilitating the entry of the photovoltaic module 300 into the clamping recess. The side of the guide part 222 facing away from the outer frame 210 is set as a curved surface to facilitate the guidance of the photovoltaic module 300.
[0049] like Figure 2 As shown, in one embodiment, the clamping part 221 is provided with a through receiving groove 224, and the fixing component 200 also includes a first rolling element 250. A plurality of first rolling elements 250 are rotatably disposed in the receiving groove 224, and the outer peripheral surface of the first rolling element 250 protrudes from the side of the clamping part 221 to abut against the photovoltaic module 300.
[0050] The first rolling element 250 is a cylindrical sleeve, which is rotatably connected and disposed within the receiving groove 224. At least a portion of the outer circumferential surface of the cylindrical sleeve protrudes from the side of the clamping portion 221, allowing the cylindrical sleeve to abut against the photovoltaic module 300. By providing the first rolling element 250 on the clamping portion 221, the clamping notch on the photovoltaic module 300 during use changes from static friction to sliding friction, reducing the frictional resistance between the photovoltaic module 300 and the clamping portion 221. This improves the convenience of manual operation, reduces time costs during operation, and also reduces wear on the photovoltaic module 300.
[0051] like Figure 2 As shown, further, a limiting protrusion 223 is provided at the end of the gripper 220 away from the guide portion 222 to limit the photovoltaic module 300. By providing the limiting protrusion 223 at the end of the gripper 220 away from the guide portion 222, the photovoltaic module 300 can be positioned by the limiting protrusion 223 when it is clamped onto the fixing component 200, thereby further ensuring the reliability of the fixing component 200 in clamping the photovoltaic module 300 and improving the stability of the photovoltaic module 300 during testing.
[0052] like Figure 1 As shown, in one embodiment, the frame 100 includes profiles 110 and reinforcing members 120. Multiple profiles 110 are connected end to end to define the frame body. The reinforcing members 120 are disposed in the plane formed by the multiple profiles 110 and are fixedly connected to the profiles 110 to enhance the strength of the frame body.
[0053] The frame body is formed by connecting multiple profiles 110 end to end, resulting in a hollow structure. Specifically, the profiles 110 can be fixedly connected by welding or by bolt locking. Reinforcing members 120 are provided on the sides of the frame body to strengthen its strength, thereby improving the reliability of the frame 100.
[0054] The frame body is constructed in a generally cuboid shape, with the top surface and one end face adjacent to the top surface of the frame 100 being open. The open end face along the length direction serves as an opening for accommodating the cavity. Multiple fixing components 200 are spaced apart on the side of the frame 100 opposite to the opening, and the fixing components 200 are spaced apart along the height direction of the frame 100. By spaced apart on the end face of the frame 100 opposite to the opening, the reliability of clamping the photovoltaic module 300 is improved.
[0055] like Figure 1As shown, in one embodiment, the frame 100 further includes a second rolling element 130. A plurality of rolling elements are spaced apart at the bottom of the frame 100 along a first direction. The second rolling element 130 is rotatably connected to the profile 110 and the reinforcing element 120. The first direction is the opening direction of the accommodating cavity.
[0056] Specifically, the first direction is the length direction of the frame 100. Second rolling elements 130 are provided at intervals along the length direction at the bottom of the frame 100 so that when the photovoltaic module 300 is installed on the frame 100, the rolling of the second rolling elements 130 can reduce the friction between the photovoltaic module 300 and the bottom of the frame 100, thereby making it easier for the operator to install the photovoltaic module 300 into the frame 100.
[0057] like Figure 1 and Figure 2 As shown in the figure, the method of using the photovoltaic module 300 reliability test bracket provided in this embodiment of the present invention is as follows:
[0058] The photovoltaic module 300 is upright and pushed into the opening of the frame 100. With the rolling of the second rolling element 130, the photovoltaic module 300 is pushed into the fixed component 200 with a little force. When the photovoltaic module 300 is aligned with the clamping notch of the fixed component 200, the photovoltaic module 300 moves towards the clamping part 221 under the guidance of the guide part 222 of the clamp 220. If the pushing force is continued to be applied to the photovoltaic module 300, the photovoltaic module 300 will exert pressure on the clamp 220, the spring will be compressed, and the photovoltaic module 300 will continue to be pushed until the photovoltaic module 300 abuts against the limiting protrusion 223.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
