Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, in particular to a pressing mechanism for a solar panel. Background Art

[0002] A solar panel is a device that can convert solar energy into electrical energy, also known as a solar panel or photovoltaic panel. By installing solar panels on outdoor spaces such as house roofs and balconies, solar panels can receive sunlight and convert it into electrical energy for human use.

[0003] The related art discloses a solar panel fixing device, which includes a nut, a pressure block and a bolt. The nut is installed in a fixed position and is provided with a screw hole. A through hole is provided in the middle of the pressure block. The bolt passes through the through hole and is screwed into the screw hole of the nut, so that the solar panel is pressed under the pressure block, thereby achieving the fixation of the solar panel. However, one side of the pressure block acts on the solar panel and lacks other support points, which can easily cause damage to the pressure block due to local stress concentration. On the other hand, the device can only be used to fix solar panels of a certain fixed thickness. For solar panels of different thicknesses, solar panel fixing devices of different sizes need to be prepared, which increases the procurement cost. Utility Model Content

[0007] In some embodiments of the present application, in the first installation state, the second free end of the second clamping plate away from the second connecting plate is pressed against the support plate; in the second installation state, the first free end of the first clamping plate away from the second connecting plate is pressed against the support plate; the distance from the inner surface of the first clamping plate to the second free end is different from the distance from the inner surface of the second clamping plate to the first free end.

[0008] In some embodiments of the present application, in the first installation state, the inner surface of the second connecting plate is pressed against the support plate; in the second installation state, the inner surface of the first connecting plate is pressed against the support plate; the distance from the inner surface of the first clamping plate to the inner surface of the second connecting plate is different from the distance from the inner surface of the second clamping plate to the inner surface of the first connecting plate.

[0009] In some embodiments of the present application, the first through hole extends from one end of the first connecting plate connected to the second connecting plate to one end of the first connecting plate connected to the first clamping plate; the second through hole extends from one end of the second connecting plate connected to the first connecting plate to one end of the second connecting plate connected to the second clamping plate.

[0010] In some embodiments of the present application, the pressure plate has an axisymmetric structure.

[0011] In some embodiments of the present application, the clamping mechanism of the solar panel also includes a slider; the fastener includes a rod portion and a cap portion connected to each other; in the first installation state, the rod portion passes through the second through hole and is locked in the slider, and the cap portion is used to clamp the second connecting plate; in the second installation state, the rod portion passes through the first through hole and is locked in the slider, and the cap portion is used to clamp the first connecting plate.

[0012] In some embodiments of the present application, the clamping mechanism of the solar panel also includes an elastic washer and a flat washer; the elastic washer and the flat washer are both sleeved on the rod portion, and the elastic washer and the flat washer are sequentially arranged between the cap portion and the pressure plate.

[0013] In some embodiments of the present application, the inner surface of the first plywood and the inner surface of the second plywood are both provided with anti-slip grooves.

[0015] It can be seen from the above technical solutions that the embodiments of the utility model have at least the following advantages and positive effects:

[0016] In the clamping mechanism of the solar panel of the embodiment of the utility model, since the first perforation is connected with the second perforation, the fastener is unlocked, the pressing plate is rotated relative to the fastener, and the fastener is relatively movable between the first perforation and the second perforation in cooperation with the movement of the pressing plate, that is, the fastener can switch between the two states of being inserted in the first perforation and being inserted in the second perforation. Then the fastener is locked to the support plate, when the fastener passes through the second perforation, the first clamping plate can clamp the solar panel with a thickness of the first clamping interval, and when the fastener passes through the first perforation, the second clamping plate can clamp the solar panel with a thickness of the first clamping interval. Since the first clamping interval and the second clamping interval are different in size, the clamping mechanism of the solar panel can be applied to the fixing of two solar panels of different thicknesses, saving the use cost. On the other hand, since the pressing plate is a stepped structure, this structural design makes the pressure distribution of the pressing plate more uniform, and during actual installation, one of the clamping plates and one connecting plate contacts the solar panel, and the other connecting plate or another clamping plate can be supported on the support plate, thereby reducing the risk of damage to the pressing plate caused by stress concentration, so that the solar panel can be stably fixed. Furthermore, the state switching of the fastener between different through-holes can be achieved by only acting on the pressure plate to make it move, thus saving the disassembly and assembly steps of the fastener needing to first withdraw from a through-hole to detach from the pressure plate and then pass through another through-hole. The operation is relatively simple, the installation efficiency is improved, and the risk of parts falling or being lost during the disassembly and assembly process can be reduced.

DETAILED DESCRIPTION

[0024] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0025] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0026] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0027] See also Figures 1 to 5The clamping mechanism of the solar panel provided by one embodiment of the utility model is used to clamp the solar panel on the support plate, which mainly includes a clamping plate 1 and a fastener 2. The clamping plate 1 is a stepped structure. The clamping plate 1 includes four plate bodies connected in sequence. Each adjacent plate body is bent in an L shape. The four plate bodies are respectively a first clamping plate 11, a first connecting plate 12, a second connecting plate 13 and a second clamping plate 14. The first connecting plate 12 is provided with a first through hole 121, and the second connecting plate 13 is provided with a second through hole 131, and the first through hole 121 is connected to the second through hole 131. In the first installation state, the fastener 2 passes through the second through hole 131 and is locked to the support plate (the support plate is not shown in the drawings), and the inner surface of the first clamping plate 11 and the support plate have a first clamping interval. In the second installation state, the fastener 2 passes through the first through hole 121 and is locked to the support plate, and the inner surface of the second clamping plate 14 and the support plate have a second clamping interval. The first clamping interval and the second clamping interval are different in size, and the fastener 2 can move between the first through hole 121 and the second through hole 131 when unlocked, so that the pressure plate 1 can be switched to the first installation state or the second installation state.

[0028] In the clamping mechanism of the solar panel of the embodiment of the utility model, since the first through hole 121 is connected with the second through hole 131, the fastener 2 is unlocked, and the pressing plate 1 is rotated relative to the fastener 2, and the fastener 2 is relatively movable between the first through hole 121 and the second through hole 131 in coordination with the movement of the pressing plate 1, that is, the fastener 2 can switch between the two states of being inserted in the first through hole 121 and being inserted in the second through hole 131. Then the fastener 2 is locked to the support plate, and when the fastener 2 passes through the second through hole 131, the first clamping plate 11 can clamp the solar panel with a thickness of the first clamping interval, and when the fastener 2 passes through the first through hole 121, the second clamping plate 14 can clamp the solar panel with a thickness of the first clamping interval. Since the first clamping interval and the second clamping interval are different in size, the clamping mechanism of the solar panel can be applied to the fixation of two solar panels of different thicknesses, saving the use cost. On the other hand, since the pressing plate 1 is a stepped structure, this structural design makes the pressure distribution of the pressing plate 1 more uniform, and during actual installation, one of the clamping plates and one of the connecting plates contacts the solar panel, and the other connecting plate or another clamping plate can be supported on the supporting plate, thereby reducing the risk of damage to the pressing plate 1 due to stress concentration, so that the solar panel can be stably fixed. Furthermore, the state switching of the fastener 2 passing through different perforations can be achieved by only acting on the pressing plate 1 to make it move, saving the disassembly and assembly steps of the fastener 2 needing to first withdraw from a perforation to detach from the pressing plate 1, and then pass through another perforation. The operation is relatively simple, the installation efficiency is improved, and the risk of parts falling or being lost during the disassembly and assembly process can be reduced.

[0029] See also Figure 1 and Figure 2It can be imagined that the pressing plate 1 rotates relative to the fastener 2, which means that the pressing plate 1 can rotate around the fastener 2 in a plane parallel to the supporting plate, so that when the fastener 2 falls into different perforations, the clamping plate used for clamping can act on the solar panel in the same horizontal orientation, and the placement position of solar panels of different thicknesses does not need to be changed. In specific usage scenarios, the rotation of the pressing plate 1 can also adapt to the need to fix the solar panel in different horizontal orientations, thereby enhancing the flexibility and adaptability of the clamping mechanism of the solar panel.

[0030] It is conceivable that the rotation of the pressure plate 1 relative to the fastener 2 is achieved through the shape fit between the first perforation 121 and the second perforation 131 and the fastener 2, that is, the pressure plate 1 can rotate around the fastener 2 through the first perforation 121, and can also rotate around the fastener 2 through the second perforation 131.

[0031] In this embodiment, in the first installation state, the first clamping plate 11 and the second connecting plate 13 are parallel to the support plate, and the first connecting plate 12 and the second clamping plate 14 are perpendicular to the support plate. In the second installation state, the first clamping plate 11 and the second connecting plate 13 are perpendicular to the support plate, and the first connecting plate 12 and the second clamping plate 14 are parallel to the support plate.

[0032] It should be noted that the clamping mechanism of the solar panel can be applied to a variety of installation scenarios.

[0033] In a specific installation scenario, in the first installation state, the second free end 141 of the second clamping plate 14 away from the second connecting plate 13 is pressed against the support plate. In the second installation state, the first free end 111 of the first clamping plate 11 away from the second connecting plate 13 is pressed against the support plate. The distance from the inner surface of the first clamping plate 11 to the second free end 141 is different from the distance from the inner surface of the second clamping plate 14 to the first free end 111. In this embodiment, the distance from the inner surface of the first clamping plate 11 to the inner surface of the second connecting plate 13 is different from the distance from the inner surface of the second clamping plate 14 to the inner surface of the first connecting plate 12, and the distance from the inner surface of the second connecting plate 13 to the second free section is the same as the distance from the inner surface of the first connecting plate 12 to the first free section.

[0034] In another specific installation scenario, in the first installation state, the inner surface of the second connecting plate 13 is pressed against the support plate. In the second installation state, the inner surface of the first connecting plate 12 is pressed against the support plate. The distance from the inner surface of the first clamping plate 11 to the inner surface of the second connecting plate 13 is different from the distance from the inner surface of the second clamping plate 14 to the inner surface of the first connecting plate 12.

[0035] See also Figure 4The first through hole 121 extends from one end of the first connecting plate 12 connected to the second connecting plate 13 to one end of the first connecting plate 12 connected to the first clamping plate 11. The second through hole 131 extends from one end of the second connecting plate 13 connected to the first connecting plate 12 to one end of the second connecting plate 13 connected to the second clamping plate 14. The connected first through hole 121 and the second through hole 131 are in an L-shaped structure, which can conveniently and labor-savingly realize the process of switching the fastener 2 between the first through hole 121 and the second through hole 131.

[0036] The pressing plate 1 is of an axisymmetric structure. Specifically, the first through hole 121 is provided in the middle of the first connecting plate 12, and the second through hole 121 is provided in the middle of the second connecting plate 13. When the fastener 2 is locked on the supporting plate, the fastening force of the fastener 2 can act on the pressing plate 1 evenly and smoothly from both sides, with the midline of the first through hole 121 and the second through hole 131 as the boundary.

[0037] See also Figures 1 to 3 , the clamping mechanism of the solar panel also includes a slider 3. The fastener 2 includes a rod portion 21 and a cap portion 22 connected to each other. In the first installation state, the rod portion 21 passes through the second through hole 131 and is locked in the slider 3, and the cap portion 22 is used to clamp the second connecting plate 13. In the second installation state, the rod portion 21 passes through the first through hole 121 and is locked in the slider 3, and the cap portion 22 is used to clamp the first connecting plate 12. Correspondingly, a slide rail is provided on the support plate (the slide rail is not shown in the accompanying drawings), and the clamping mechanism of the solar panel is installed on the support plate through the cooperation between the slider 3 and the slide rail, and the clamping mechanism of the solar panel can be driven to adjust its position through the sliding of the slider 3 to adapt to the actual fixing requirements of the solar panel.

[0038] The pressing mechanism of the solar panel also includes an elastic washer 4 and a flat washer 5. The elastic washer 4 and the flat washer 5 are both sleeved on the rod 21, and the elastic washer 4 and the flat washer 5 are sequentially arranged between the cap 22 and the pressing plate 1. The arrangement of the elastic washer 4 and the flat washer 5 can provide a certain elasticity and buffering effect, so that the pressing mechanism can more stably press the solar panel.

[0039] See also Figures 1 to 5 The inner surface of the first clamping plate 11 and the inner surface of the second clamping plate 14 are both provided with anti-slip grooves, which can increase the friction of clamping to ensure that the solar panel will not slide or loosen during the installation process.

[0040] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
