Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and more specifically to a frame accessory assembly device and a photovoltaic bracket. Background Technology

[0002] In photovoltaic systems, many electronic devices need to be directly mounted onto the frame of solar modules. Conventional solar module frames have relatively wide borders (01). Figure 1A It can be conveniently assembled into electronic devices by using clips 02 with screws for fixing, or by using adapter plates 03 with screws for fixing. Figure 1B , Figure 1C The clip 02 is fixed to the electronic device with screws. The clip 02 is elastic, and the hooks on the clip 02 can engage with the corresponding slots on the frame. The adapter plate 03 is fixed to the electronic device with screws, and the adapter plate 03 is fixed to the frame with screws. All of the above assembly methods require a large overlap area between the adapter component and the frame, and one type of adapter component can only be assembled with a frame of a specific size.

[0003] Due to the development and cost optimization of solar modules, more and more narrow-bezel modules are appearing on the market. Figure 1D The assembly surface is significantly narrowed, making it impossible for conventional assembly structures to stably support the assembly.

[0004] For those skilled in the art, how to solve the adaptation problem of different specifications of border components is a technical problem that needs to be solved. Utility Model Content

[0005] The core of this utility model is to provide a frame accessory assembly device, which can be adapted to frame widths of different widths by using different hooks to fit the frame. The specific solution is as follows:

[0006] A frame accessory assembly device includes an assembly part, a locking part, and a locking component, wherein the assembly part and the locking part are fixed together.

[0007] The first side of the assembly part in the thickness direction is used to install frame accessory equipment, and the second side is provided with at least two hooks. The hooks have a height difference in the height direction and a thickness difference in the thickness direction. Each hook can be independently hooked to the edge of the frame, and the corresponding contact surface of the hook can be in contact with the side wall of the frame.

[0008] The locking component is installed on the locking part, and the locking component is used to press against the surface perpendicular to the frame along the height direction, thereby tightening the hook.

[0009] Optionally, the assembly part is provided with a locking hole for a fixing screw to pass through and be screwed onto the frame accessory device.

[0010] Optionally, the assembly part has a positioning block protruding from the back of the frame, and the positioning block is used to position the frame accessory equipment.

[0011] Optionally, the assembly part has a cut-out area facing away from the frame.

[0012] Optionally, the locking part includes vertical walls and horizontal walls that are perpendicular to each other, and the end of the vertical wall is fixed to the assembly part.

[0013] Optionally, a screw hole is provided on the transverse wall, and the locking component is a pointed screw. The locking component is threaded into the screw hole, and the tip of the pointed screw is used to press against the frame.

[0014] Optionally, at least two screw holes are arranged along the thickness direction of the vertical wall.

[0015] Optionally, a thinning deformation zone is provided on the vertical wall, and the thickness of the thinning deformation zone is less than the thickness at other locations.

[0016] Optionally, the width of the locking part is less than or equal to the width of the mounting part.

[0017] This utility model also provides a photovoltaic bracket, wherein at least one of the frame accessory assembly devices described in any one of the above claims is provided on its frame.

[0018] This utility model provides a frame accessory assembly device, in which the assembly part and the locking part are fixed as one piece. The first side of the assembly part in the thickness direction is used to install the frame accessory equipment, and the second side is provided with at least two hooks. Because the hooks have height differences in both the height and thickness directions, each hook can be independently hooked onto the edge of the frame, and the corresponding contact surface of the hook can be in contact with the side wall of the frame. When the locking component on the locking part presses against the surface perpendicular to the frame in the height direction, the hooks can be pressed tightly against the edge of the frame to form a hook-lock. The contact between the contact surface and the surface of the frame makes the fit more stable. Since two or more hooks are provided, when applied to frames of different widths, different hooks can be used to form a hook-lock fit, which can be applied to frames of different specifications and solves the adaptation problem of frame components of different specifications.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the frame accessory assembly device and photovoltaic bracket of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This utility model provides a frame accessory assembly device, combined with Figure 5 , Figure 6 As shown, it includes an assembly part 1, a locking part 2, and a locking component 3. The assembly part 1 and the locking part 2 are fixed as one unit, and are two different parts of an integral structure. The locking component 3 is an independently set structure, which is assembled with the assembly part 1 and the locking part 2 to form an integral assembly.

[0037] In the thickness direction, as Figure 2 In this text, the X-axis represents the width, the Y-axis represents the width, and the Z-axis represents the height. The references to height and width in this document are based on the assembly direction shown in the attached diagram and do not necessarily imply adherence to the direction shown in the diagram. The first side of the assembly section 1 in the thickness direction is used to install frame accessory equipment, including shut-off devices, optimizers, and micro-inverters. The second side of the assembly section 1 in the thickness direction is provided with at least two hooks 11 for engaging with the frame. Figure 4 As shown, the assembly part 1 is the lower part, the locking part 2 is the upper part, the left side is the first side, and the right side is the second side. The left side of the assembly part 1 is used to install the frame accessory equipment, and the right side is used to match the frame.

[0038] The number of hooks 11 is set to two or more. In the structure shown in the attached drawings of this application, three hooks 11 are used as an example. The hooks 11 have a height difference and a thickness difference, respectively. Figure 4 Taking the displayed structure as an example, the height difference between the upper hook 11 and the middle hook 11 is H12, and the height difference between the middle hook 11 and the lower hook 11 is also H12; the thickness difference between the left hook 11 and the middle hook 11 is D12, and the thickness difference between the middle hook 11 and the right hook 11 is D23. The width of each hook 11 can remain equal. Due to the stepped, staggered distribution of the hooks 11, each hook 11 can independently hook onto the edge of the frame. During use, one hook 11 can be selected to hook onto the frame.

[0039] In this invention, each hook 11 is provided with a corresponding contact surface 12. Each hook 11 can be independently hooked onto the edge of the frame, and the contact surface 12 corresponding to the hook 11 can be attached to the side wall of the frame. Figure 4 As shown, each hook 11 is a protruding block structure with a groove formed between the hook 11 and the mating surface 12. This groove is used for the edge of the frame to engage. The height of the mating surface 12 is higher than the height of the hook 11. When assembled with the frame, the mating surface 12 is in contact with the side wall of the frame, so that the two surfaces form a stable contact to prevent wobbling.

[0040] Locking component 3 is installed on locking part 2, such as Figure 5 , Figure 6 As shown, the locking component 3 is mounted on the top surface of the locking part 2, and the locking component 3 can move in the height direction to adjust its position. (Combined with...) Figure 9 , Figure 10 As shown, when the hook 11 is hooked onto the lower edge of the vertical sidewall of the frame A, the sidewall of the frame A contacts the mating surface 12. At this time, the top surface of the locking part 2 is located above the top surface of the frame A, and there is a gap between the top surface of the locking part 2 and the top surface of the frame A. The locking member 3 presses against the upper surface perpendicular to the frame along the height direction, and the bottom of the locking member 3 contacts the upper surface of the frame. When the locking member 3 moves relative to the locking part 2, it can lift the locking part 2 upward, thereby tightening the hook 11. The lower edge of the sidewall of the frame is tightly embedded in the hook 11, forming a tension fit, thereby achieving fixation.

[0041] Because the frame accessory assembly device of this utility model has two or more hooks, combined with Figure 9 As shown, border A is a narrow border with narrow sidewalls. The upper hook 11 is engaged with the lower edge of the sidewall of border A. Figure 10 As shown, frame A is a wide frame with wider sidewalls. The middle hook 11 is engaged with the lower edge of the sidewall of frame A. If a wider frame is available, the lower hook 11 can be used. Hooks 11 in different positions can accommodate various frame sizes. Each hook 11 can be locked in place by adjusting the height of the locking component 3. By adjusting the position of the locking component 3, each hook 11 can also accommodate different frame sizes within a certain range, further expanding the compatibility. This frame accessory assembly device solves the problem of adapting frame components of different specifications.

[0042] Assembly part 1 is provided with locking holes 13 for the fixing screws 4 to pass through and be screwed onto the frame accessory equipment. Figure 2 , Figure 3As shown, the locking hole 13 is provided through the X-axis direction, that is, it is opened along the thickness direction. The fixing screw 4 can be inserted into the locking hole 13. The stud end of the fixing screw 4 passes through the locking hole 13 and is threadedly connected to the frame accessory device, thereby realizing the fixing of the frame accessory device.

[0043] Combination Figure 2 , Figure 5 As shown, a positioning block 14 protrudes from the assembly part 1 away from the frame, that is, a positioning block 14 is provided on the first side of the assembly part 1. The positioning block 14 protrudes from the assembly part 1 to form a horizontal protrusion. The protruding direction of the positioning block 14 is away from the frame. The positioning block 14 is used to position the frame accessory equipment. Figure 7 , Figure 8 As shown, when the frame accessory device B is installed, the side wall of the frame accessory device B contacts the first side of the assembly part 1, and the top surface of the frame accessory device B contacts the positioning block 14, thereby restricting the position of the frame accessory device B in the X-axis and Z-axis directions, thus facilitating quick positioning and matching.

[0044] Combination Figure 4 , Figure 6 As shown, the assembly part 1 has a hollowed-out area 15 facing away from the frame, that is, a hollowed-out area 15 is provided on the first side of the assembly part 1. The hollowed-out area 15 has no solid structure, which can reduce weight. Since the locking hole 13 needs to be opened on the assembly part 1, a large thickness is required to ensure structural strength. The hollowed-out area 15 removes part of the solid structure, which can achieve weight reduction.

[0045] Based on any of the above technical solutions and their combinations, the locking part 2 of this utility model includes a vertical wall 201 and a horizontal wall 202 that are perpendicular to each other. The vertical wall 201 and the horizontal wall 202 are fixed relative to each other to form an "L"-shaped bent structure. The end of the vertical wall 201 is fixed to the assembly part 1, and then... Figure 4 As shown, the bottom end of the vertical wall 201 is fixedly connected to the assembly part 1.

[0046] Combination Figure 2 , Figure 3 As shown, in some embodiments, a screw hole 21 is provided on the transverse wall 202. The screw hole 21 has an internal thread and is vertically through. The locking component 3 is a pointed screw with an external thread on its outer wall, which can form a threaded engagement with the screw hole 21. Tightening the pointed screw allows it to move up and down. The locking component 3 is threaded into the screw hole 21. When the pointed screw is tightened downwards, the tip of the pointed screw presses against the upper surface of the frame, ensuring a more secure contact with the frame.

[0047] At least two screw holes 21 are arranged along the thickness direction of the vertical wall 201, and the number of screw holes 21 may be more than two. Figure 2 , Figure 3 As shown, two screw holes 21 are arranged in the X-axis direction. The two screw holes 21 are of the same specification, and either one can be used with the locking component 3. When different hooks 11 are used with the frame, the locking component 3 can be inserted into different screw holes 21. For example... Figure 9 As shown, the upper hook 11 engages with the frame, at which point the locking component 3 is inserted into the screw hole 21 closer to the vertical wall 201; as Figure 10 As shown, the middle hook 11 engages with the frame, at which point the locking component 3 is inserted into the screw hole 21 further away from the vertical wall 201. Depending on the choice of screw hole 21, the locking component 3 should be positioned as directly as possible opposite the hook 11 in use. Of course, if necessary, the locking component 3 can be installed in both screw holes 21, and the two locking components 3 can be locked to the frame, further improving the stability of the locking mechanism.

[0048] In some embodiments, a thinning deformation region 22 is provided on the vertical wall 201, and the thickness of the thinning deformation region 22 is less than the thickness at other locations. Figure 4 , Figure 5 As shown, the thinning deformation zone 22 is located on the side away from the frame, i.e., the first side; the thinning deformation zone 22 can also be located on the side of the vertical wall 201 closer to the frame, i.e., the second side. The thinning deformation zone 22 is a curved arc surface, and the thickness of the thinning deformation zone 22 is less than the thickness of other areas of the vertical wall 201, making the thinning deformation zone 22 more prone to bending deformation.

[0049] Since the vertical wall 201 and the horizontal wall 202 are L-shaped bent structures, when the locking component 3 is locked, the vertical wall 201 and the horizontal wall 202 will deform. In order to avoid deformation of the lower assembly part 1, a thinning deformation area 22 is provided on the vertical wall 201 so that the deformation is mainly concentrated in the thinning deformation area 22. The lower assembly part 1 is almost undeformed, and the frame accessory equipment will not be subjected to compressive force, thereby avoiding damage to the frame accessory equipment due to stress concentration after long-term use.

[0050] In this invention, the width of the locking part 2 is less than or equal to the width of the assembly part 1, allowing for equal widths at all positions. Since the assembly part 1 needs to contact the frame and frame accessory equipment, a larger width creates a larger contact surface, making the assembly more stable.

[0051] This utility model also provides a photovoltaic bracket, combined with Figure 9 , Figure 10As shown, at least one of the aforementioned frame accessory assembly devices is provided on its frame A for fixing the frame accessory device B. A frame accessory device with a smaller width can be fixed to the frame using only one frame accessory assembly device, while a frame accessory device with a larger width can be fixed to the frame using two or more frame accessory assembly devices. This photovoltaic bracket can achieve the aforementioned technical effects.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
