Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0037] With the continuous progress of technology, photovoltaic panels have been widely used in power supply and lighting systems in the fields of home, business and industry. In the field of home application, photovoltaic panels can be used in outdoor lighting systems, solar stoves, solar water heaters, etc.; in the fields of business and industrial application, photovoltaic panels can be used in solar lighthouses, solar factories, solar agricultural greenhouses, etc. In addition, there are some areas that apply photovoltaic panels to solar power stations to generate a large amount of electricity to supply cities and rural areas.

[0038] In the related prior art, the photovoltaic panel is installed on the support by erecting the support on the installation site and then installing the photovoltaic panel on the support in a flat manner. This installation method is only applicable to installation on the top of a building or on the ground and cannot meet the installation requirements of a vertical installation surface such as a glass curtain wall and an installation close to a vertical angle.

[0039] To this end, the embodiment of the present application proposes a photovoltaic panel installation support capable of realizing vertical installation of a photovoltaic panel.

[0040] With reference to Figures 1 to 3 The photovoltaic panel installation support of the embodiment specifically comprises a bottom frame 100, a clamping assembly 200, and an adjusting assembly. The clamping assembly 200 is provided with a clamping portion 201 and a plurality of connecting portions 202. The plurality of connecting portions 202 are distributed in parallel. One end of the connecting portion 202 is rotationally connected to the bottom frame 100, and the other end is rotationally connected to the clamping portion 201, so that the clamping portion 201 can approach or move away from the bottom frame 100 along a first direction under the connection of the plurality of connecting portions 202. It can be understood that when the clamping portion 201 approaches or moves away from the bottom frame 100 along the first direction, the moving path is not along the first direction, but a translation movement formed based on the rotation of the connecting portion 202. The adjusting assembly is arranged between the bottom frame 100 and the clamping portion 201 and is used to control the clamping portion 201 to move along a second direction, and the second direction intersects the first direction. When the adjusting assembly controls the clamping portion 201 to move along the second direction, the clamping portion 201 will synchronously approach or move away from the bottom frame 100 along the first direction.

[0041] The photovoltaic panel installation support of the embodiment, since the clamping portion 201 approaches or moves away from the bottom frame 100 along the first direction, and the adjusting assembly controls the clamping portion 201 to move along the second direction, when the clamping portion 201 and the bottom frame 100 clamp the photovoltaic panel, the reaction force received by the clamping portion 201 forms a certain angle with the second direction instead of directly acting on the adjusting assembly along the second direction, which is beneficial to ensuring the stability of the adjusting assembly, i.e., the position of the clamping portion 201 is stable and is not prone to uncontrolled loosening.

[0042] The photovoltaic panel installation support of the embodiment, the clamping portion 201 and the bottom frame 100 form a parallelogram mechanism through the plurality of connecting portions 202, and the clamping assembly 200 approaches or moves away from the bottom frame 100 through the movement adjustment of the clamping portion 201, so that the clamping portion 201 and the bottom frame 100 can realize opening and closing adjustment. Only the bottom frame 100 needs to be installed on a glass curtain wall or other installation base body, and then the photovoltaic panel is placed between the bottom frame 100 and the clamping portion 201, and the clamping portion 201 can clamp the photovoltaic panel through the adjusting assembly, thereby completing the installation of the photovoltaic panel under a vertical angle condition such as a glass curtain wall and solving the problem that the traditional support cannot meet the installation requirements. It can be applied to installation of photovoltaic panels on glass curtain walls and installation of photovoltaic panels on floor windows of ordinary residential homes.

[0043] And because the photovoltaic panel is clamped by the bottom frame and the clamping part, it can be quickly installed and removed, and the photovoltaic panel can be installed for sunshade in summer and removed for lighting in winter, which can solve the application demand problem that the traditional support cannot realize, is suitable for the additional demand of shopping mall glass curtain wall, and can be installed and removed according to the seasonal sunlight demand, and is firm and does not damage the glass.

[0044] The photovoltaic panel mounting support of the embodiment can adapt to the installation of photovoltaic panels of different sizes between the clamping part and the bottom frame when the connecting part is perpendicular to the bottom frame, so the application range is wide. The actual installable thickness is preferably controlled to be 2mm-40mm to be compatible with the installation of most photovoltaic panels.

[0045] According to different installation requirements, the bottom frame 100 can be installed by punching and screwing, or pre-buried with bolts, or fixed by gluing, and the person skilled in the art can flexibly set according to the needs.

[0046] Referring to Figure 1 and Figure 3 In some embodiments of the present application, the adjusting assembly includes a support seat 1011, an adjusting seat 1014, an adjusting screw 1012 and an adjusting part 1013. The support seat 1011 and the adjusting seat 1014 are fixedly arranged on the bottom frame 100 and the clamping part 201 respectively, and are spaced apart along the second direction. The support seat 1011 is provided with an adjusting groove extending along the first direction. The adjusting seat 1014 is provided with a threaded hole. The adjusting screw 1012 is installed in the threaded hole and passes out of the adjusting groove along the second direction. The adjusting part 1013 is connected to one end of the adjusting screw 1012 passing through the adjusting groove, for limiting the movement of the adjusting screw 1012 to one side of the clamping part 201.

[0047] It can be understood that the size of the adjusting part 1013 is greater than the width of the adjusting groove, thereby limiting the movement of the adjusting screw 1012 to one side of the clamping part 201 along the second direction.

[0048] With the structure of the embodiment, only the rotation of the adjusting screw 1012 needs to be controlled by the adjusting part 1013, and the movement of the adjusting seat 1014 along the second direction can be controlled. Under the action of the connecting part 202, the clamping part 201 will move synchronously towards or away from the bottom frame 100 along the first direction. Because of the adjusting groove, the adjusting screw 1012 can move along the first direction, thereby keeping synchronous movement with the clamping part 201.

[0049] In application, first, the adjusting screw 1012 is controlled to rotate by the adjusting part 1013, so that the clamping part 201 is away from the bottom frame 100, then the photovoltaic panel is placed between the clamping part 201 and the bottom frame 100, and then the adjusting screw 1012 is controlled to rotate by the adjusting part 1013, so that the clamping part 201 moves along the second direction, at this time, the clamping part 201 is synchronized to move to the first direction and close to the bottom frame 100 under the action of the connecting part 202, until the photovoltaic panel is clamped.

[0050] In the process of clamping the photovoltaic panel, the clamping part 201 cannot drive the adjusting screw 1012 to rotate because the force acting on the clamping part 201 is away from the bottom frame 100 along the first direction. And because the photovoltaic panel is clamped, the clamping part 201 cannot move further along the second direction to the direction of the adjusting part 1013, and in the opposite direction, it cannot move along the second direction to the direction of the adjusting seat 1014 because it is limited by the clamping of the adjusting part 1013. Therefore, the structure of the embodiment is simple, and the stability of the clamping process can be effectively guaranteed, and the situation of uncontrolled loosening does not occur.

[0051] The adjusting seat 1014 and the supporting seat 1011 can be fixedly connected with the clamping part 201 and the bottom frame 100 respectively by an integrated setting mode, or by a welding or bolt connection mode.

[0052] In combination Figure 3 In some embodiments of the present application, the adjusting part 1013 is rotatably installed on the adjusting screw 1012 along the radial direction of the adjusting screw 1012, and the adjusting part 1013 has a first rotation position and a second rotation position. When the adjusting part 1013 rotates from the first rotation position to the second rotation position, the adjusting seat 1014 is pulled to the supporting seat 1011 along the second direction by the adjusting screw 1012, that is, when the adjusting part 1013 rotates to the second rotation position, the adjusting screw 1012 is pulled to move along the second direction, so that the clamping part 201 is close to the bottom frame 100. On the contrary, when the adjusting part 1013 rotates from the second rotation position to the first rotation position, the adjusting seat 1014 is pulled away from the supporting seat 1011 along the second direction by the adjusting screw 1012. That is, when the adjusting part 1013 rotates to the first rotation position, the adjusting screw 1012 is pulled to move along the second direction, so that the clamping part 201 is away from the bottom frame 100. It should be noted that the adjusting part 1013 moves the adjusting screw 1012 along the second direction when rotating from the first rotation position to the second rotation position, and when rotating from the second rotation position to the first rotation position, but the moving directions are opposite.

[0053] With the structural arrangement of the embodiment, the opening and closing adjustment of the clamping portion 201 can be realized by adjusting the rotation of the adjusting portion 1013. In actual application, the adjusting screw 1012 can be used to adjust the rotation of the adjusting portion 1013, so as to move the clamping portion 201 to a proper distance from the bottom frame 100. When the photovoltaic panel is installed, the adjusting portion 1013 is only needed to be rotated to the first rotation position, the photovoltaic panel is placed between the clamping portion 201 and the bottom frame 100, and then the adjusting portion 1013 is rotated to the second rotation position, so as to naturally complete the clamping of the photovoltaic panel. When the photovoltaic panel needs to be taken out, the adjusting portion 1013 is only needed to be rotated to the first rotation position.

[0054] With the structural arrangement of the embodiment, the distance between the clamping portion 201 and the bottom frame 100 can be adjusted by the adjusting portion 1013 and the adjusting screw 1012 during the rotation of the adjusting portion 1013 relative to the adjusting screw 1012, so as to realize the quick clamping and quick release of the photovoltaic panel by the rotation of the adjusting portion 1013, which is beneficial to improve the convenience of disassembly and assembly of the photovoltaic panel. Moreover, the initial distance adjustment of the clamping portion 201 to the bottom frame 100 by the adjusting portion 1013 and the adjusting screw 1012 can adapt to the installation of photovoltaic panels with different thicknesses, and can improve the versatility.

[0055] In some embodiments of the present application, the second rotation position is the motion dead point of the adjusting portion 1013. As described in the foregoing embodiments, when the photovoltaic panel is clamped, the adjusting portion 1013 is in the second rotation position. The embodiment can effectively ensure the stability of clamping by designing the motion dead point of the adjusting portion 1013 as the second rotation position, so as to avoid the non-controlled loosening.

[0056] In combination with the foregoing description of the embodiments, the adjusting portion 1013 is in the second rotation position when the photovoltaic panel is clamped. Figure 3In some embodiments of the present application, the adjusting portion 1013 is provided with a pin hole, and one end of the adjusting portion 1013 abutting against the support seat 1011 is provided with a first curved surface protruding outward, which is parallel to the axis of the pin hole. The adjusting screw 1012 is provided with a pin radially, which is inserted into the pin hole. The first curved surface abuts against the support seat 1011 during the rotation of the adjusting portion 1013 around the pin. The distance D between the axis of the pin hole and the support seat 1011 is the smallest when the middle position of the first curved surface abuts against the support portion, and the distance D increases when the adjusting portion 1013 rotates to either end of the first curved surface, and the distance D is larger when the adjusting portion 1013 is closer to the end of the first curved surface. The end of the adjusting portion 1013 away from the support seat 1011 is provided with an arc-shaped extension 1015, and when the adjusting portion 1013 rotates around the pin to abut against the end of the first curved surface, the end of the arc-shaped extension 1015 abuts against the support seat 1011, and a hollow area is formed between the arc-shaped extension 1015 and the support seat 1011 based on the curvature of the arc-shaped extension 1015. When the end of the arc-shaped extension 1015 abuts against the support seat 1011, the axis of the adjusting screw 1012, the axis of the pin and the abutting position of the first curved surface and the support seat 1011 are collinear in the second direction, or the axis of the adjusting screw 1012 is located on the side of the abutting position of the first curved surface and the support seat 1011 close to the end of the arc-shaped extension 1015.

[0057] With the structure of the present embodiment, the first rotation position is the angle position of the middle position of the first curved surface abutting against the support seat 1011, and the second rotation position is the angle position of the end of the arc-shaped extension 1015 abutting against the support seat 1011. In the first rotation position, the distance D is the smallest, and no matter which side the adjusting portion 1013 rotates to, the distance D will increase, which will exert a force on the adjusting screw 1012 and the clamping portion 201, so that the stability of the adjusting portion 1013 in the first rotation position can be effectively ensured when no external force is applied. In the second rotation position, the arc-shaped extension 1015 abuts against the support seat 1011, which is in a folded state, and the situation of being accidentally touched can be avoided as much as possible. In addition, the hollow area is formed between the arc-shaped extension 1015 and the support seat 1011, which facilitates the rotation operation of the staff holding the arc-shaped extension 1015.

[0058] It should be noted that the surface of the adjusting portion 1013 abutting against the support seat 1011 can also be a cylindrical surface, so that the opening and closing of the clamping portion 201 is controlled by only rotating the adjusting screw 1012, and the abutting against the support seat 1011 and the unfolding relative to the support seat 1011 are realized by the rotation of the adjusting portion 1013.

[0059] Reference Figure 2In some embodiments of the present application, the bottom frame 100 comprises a left side frame 101 and a right side frame 102, and both the left side frame 101 and the right side frame 102 are provided with a clamping assembly 200 and an adjusting assembly. In actual application, the photovoltaic panel is clamped by the left and right clamping assemblies 200, so as to ensure the installation stability of the photovoltaic panel.

[0060] In addition, the left side frame 101 and the right side frame 102 are used to support the photovoltaic panel, and space can be reserved in the middle to avoid excessive shielding of the installation base by the bottom frame 100.

[0061] It can be understood that the first direction in the present embodiment is the front-back direction of the angle shown in the figure, and the second direction is the vertical direction. Figure 1

[0062] Referring to Figure 1 In some embodiments of the present application, the bottom frame 100 further comprises a lower side frame 103, which is vertically arranged between the lower ends of the left side frame 101 and the right side frame 102, and the lower side frame 103 is provided with a limiting groove 1031 which is open at the upper end. The limiting groove 1031, the left side frame 101, the right side frame 102 and the clamping assembly 200 together define a slot for the photovoltaic panel to be inserted from the upper end. In application, the photovoltaic panel is inserted downward from between the left side frame 101, the right side frame 102 and the corresponding clamping assembly 200, and is clamped into the limiting groove 1031, which can effectively ensure the stability of the installation.

[0063] In installation, the photovoltaic panel can be directly inserted into the slot from the upper end, and the staff can loosen the photovoltaic panel to tighten the clamping assembly 200 by using the support of the limiting groove 1031, which is convenient to operate.

[0064] In some embodiments of the present application, the left side frame 101 and the right side frame 102 are slidingly connected to the lower side frame 103 to flexibly adjust the distance between the left side frame 101 and the right side frame 102, so as to adapt to the installation requirements of photovoltaic panels of different sizes. The left side frame 101, the right side frame 102 and the lower side frame 103 can be slidingly matched and locked by using a structure such as a marume nut, or other structures in the prior art can be used.

[0065] In some embodiments of the present application, the lower side frame 103 is fixedly connected to the left side frame 101, and the right side frame 102 can move up and down and / or left and right relative to the left side frame 101 as needed. In installation, the lower side frame 103 and the left side frame 101 are first installed on the installation base, then the position of the right side frame 102 is determined according to the size of the photovoltaic panel, and is then installed and fixed, and then the photovoltaic panel is inserted and fixed.

[0066] The structure of the present embodiment can adapt to the installation of photovoltaic panels of different sizes without changing the structure of the photovoltaic panel mounting bracket, and has a wide range of applications.​

[0067] In some embodiments of the present application, the photovoltaic panel mounting bracket further comprises a fall-preventing steel wire connected to the bottom frame 100. During installation, the fall-preventing steel wire is fixed to the installation base to ensure safety.

[0068] In combination with the structure of the foregoing embodiments, when the right frame 102 is independently arranged from the lower frame 103 and the left frame 101, the right frame 102 and the left frame 101 are both provided with a fall-preventing steel wire.

[0069] The present embodiment can provide safety protection during installation of the photovoltaic panel mounting bracket, avoid falling of the photovoltaic panel mounting bracket during installation, and provide a safety insurance after installation is completed, thereby effectively improving safety from installation to application.

[0070] In some embodiments of the present application, a glue layer is arranged on the side of the bottom frame 100 away from the clamping portion 201 in the first direction.

[0071] It can be understood that the side of the bottom frame 100 away from the clamping portion 201 is the installation side connected to the installation base. The present embodiment connects the installation base by arranging a glue layer, which has a wider range of application than the form of punching installation and does not need to damage the installation base. For example, when installing on a glass curtain wall, punching installation will damage the integrity of the glass curtain wall, and the safety of the entire glass curtain wall needs to be evaluated. However, the fixed form of gluing can effectively avoid such problems and can be installed on any position of the glass curtain wall as needed.

[0072] In some embodiments of the present application, the glue layer comprises structural glue and foam adhesive strips arranged on both sides of the structural glue. Taking the left frame 101 as an example, a strip of structural glue is vertically arranged at the middle position of the left frame 101 in the width direction of the left frame 101, and foam adhesive strips are arranged on both sides of the structural glue. During installation, the foam adhesive strips can provide sufficient temporary adhesion to ensure the stability of the left frame 101 and provide sufficient time for curing of the structural glue, which can avoid falling of the structural glue due to uncured. At the same time, the foam adhesive strips are solid structures and the structural glue is a fluid structure. By arranging foam adhesive strips on both sides of the structural glue, a regular space can be defined to accommodate the structural glue, and the structural glue can be prevented from overflowing, which can improve the firmness of gluing and the overall integrity and aesthetics of the appearance.

[0073] In actual application, the bottom frame 100 is first installed on the glass curtain wall, and the photovoltaic panel is installed on the bottom frame 100 when the bonding force is sufficient, or the photovoltaic panel is installed after waiting for a certain period of time when the bonding force is insufficient, and clamping is performed through the clamping assemblies on the left side frame 101 and the right side frame 102. The connecting line of the photovoltaic panel can be connected to the control cabinet or the corresponding electrical equipment through the hole on the glass curtain wall.

[0074] In some embodiments of the present application, the clamping part 201 is provided in an L-shaped structure, and the clamping part 201 includes a clamping wall 2012 opposite to the left side frame 101 and the right side frame 102 and a mounting wall 2011 located on the outer side, and the mounting walls 2011 on the two clamping parts 201 are connected perpendicularly to one ends of the two clamping walls 2012 away from each other. The connecting part 202 is rotationally arranged on the mounting wall 2011 and connected to the outer side walls of the left side frame 101 and the right side frame 102 in the front-rear direction. The left side frame 101 and the right side frame 102 are limited by the connecting part 202 on both sides between the left side frame 101 and the right side frame 102 and the clamping part 201. Among them, the clamping wall 2012 is arranged with multiple cut-off grooves in the vertical direction, so that the clamping wall 2012 is divided into multiple plates in the vertical direction. Each plate is provided with an elastic structure such as a rubber block on the side facing the opposite left side frame 101 or right side frame 102. By arranging the elastic structure on the clamping part 201, the structure of the present embodiment can improve the pressing effect when pressing the photovoltaic panel, and avoid damage caused by hard contact between the two.
