Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and particularly to a photovoltaic balcony bracket. Background Art

[0002] In the prior art, with the continuous growth of global energy demand and the increasingly serious environmental pollution problems, the development and utilization of clean energy have become the consensus of countries around the world. As a clean energy source, solar energy has received more and more attention in its development and utilization. Photovoltaic power generation technology uses solar cells to directly convert solar light energy into electrical energy, which has the advantages of being clean, safe, and reliable, and has become one of the important ways of solar energy utilization.

[0003] In recent years, the continuous development of photovoltaic power generation technology and the reduction of costs have made its application scope wider and wider, and it has been extended from large-scale ground power stations to distributed photovoltaic power generation systems, such as rooftop photovoltaics, BIPV (Building Integrated Photovoltaics), etc. As an important part of residential buildings, balconies usually have a certain amount of idle space and good lighting conditions, which are very suitable for installing photovoltaic power generation systems and have become an ideal place for household distributed photovoltaic power generation.

[0004] However, when the existing photovoltaic brackets are applied to balcony photovoltaics, there are problems in that it is difficult to balance performance and cost. Some brackets, in order to pursue high performance, such as using complex angle adjustment mechanisms or high-strength materials, result in higher costs; while some low-cost brackets often have deficiencies in performance, such as low strength, poor stability, and inconvenient installation.

[0005] Therefore, there is an urgent need for a photovoltaic bracket that is easy to install, has adjustable angles, high structural strength, beautiful appearance, and moderate cost to meet the growing demand for balcony photovoltaic applications and solve the problem that it is difficult to balance performance and cost in the existing brackets. Summary of the Invention

[0006] To solve the above problems, the present invention provides a photovoltaic balcony bracket with a simple structure, few components, and easy to process and assemble.

[0007] To achieve the above object, the photovoltaic balcony bracket designed by the present invention includes a photovoltaic back frame, a bracket body, and a connecting member. At least two bracket bodies are spaced apart on the photovoltaic back frame. Each bracket body includes a first strut, a second strut, and an adjusting rod.

One end of the second strut is pivotally connected to one end of the first strut, and the second strut is provided with mounting holes for fixing on a building and a plurality of adjusting holes spaced along the length direction of the second strut. One end of the adjusting rod is pivotally connected to the middle of the first strut, and the other end is selectively pivotally connected to any one of the adjusting holes on the second strut through a connecting member.

[0008] For easy disassembly and assembly, the connecting member is a bolt or a pin.

[0009] To adapt to different installation environments, the number of adjustment holes on the second support rod is 3 - 5.

[0010] Further, the number of adjustment holes on the second support rod is 4, and the positions of the adjustment holes are set such that the second support rod can form any one of the angles of 15 degrees, 25 degrees, 35 degrees, and 45 degrees with respect to the first support rod.

[0011] To reduce weight and improve its strength, the first support rod, the second support rod, and the adjustment rod are all made of aluminum alloy, and their cross - sections are all L - shaped.

[0012] To make the connection more firm, connection ears are provided at one end where the first support rod and the second support rod are pivotally connected and at both ends of the adjustment rod. Each connection ear is provided with a through - hole, and the connecting member passes through the through - hole to connect the first support rod, the second support rod, and the adjustment rod to each other.

[0013] To adapt to more installation scenarios, a hook is fixedly installed at one end of the second support rod pivotally connected to the first support rod, and the opening of the hook faces the position where the adjustment rod is pivotally connected to the second support rod.

[0023] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Embodiment 1.

[0025] As Figure 1 shown, the photovoltaic balcony support described in this embodiment includes a photovoltaic back frame 100, a support body 200, and a connecting member 300. Among them, the photovoltaic back frame 100 is a standard photovoltaic module back frame for fixing photovoltaic modules, and at least two support bodies 200 are arranged at intervals on the photovoltaic back frame 100 to provide stable support for the photovoltaic back frame 100.

[0026] Specifically, two support bodies 200 are provided, and each support body 200 includes:

[0027] A first support rod 10. In this embodiment, the first support rod 10 is made of aluminum alloy and is fixedly installed on the back of the photovoltaic back frame 100 by means of bolts or rivets to provide the main supporting force for the support. The second support rod 2 is also made of aluminum alloy. One end of it is pivotally connected to one end of the first support rod 10 to form an adjustable-angle connection. And an installation hole 21 for fixing on a building is provided on the second support rod 20. For example, an expansion bolt can be installed at the installation hole 21 to fix the second support rod 20 on the balcony wall to achieve a stable installation.

[0028] In addition, a plurality of adjustment holes 22 are also arranged at intervals along the length direction on the second support rod 20. The adjustment rod 30 is made of aluminum alloy and has an L-shaped cross section. One end of it is pivotally connected to the middle of the first support rod 10, and the other end is selectively pivotally connected to any one of the adjustment holes 22 on the second support rod 20 through the connecting member 300. That is, by selecting different adjustment holes 22, the included angle between the second support rod 20 and the first support rod 10 can be adjusted, so as to adjust the inclination angle of the photovoltaic module, so that it can obtain the best sunlight irradiation angle and improve the power generation efficiency. In this embodiment, as Figure 3 shown, the connecting member 300 can be a bolt or a pin. Preferably, a bolt is used in specific implementation to better fix and connect the adjustment rod 30 and the second support rod 20 after the inclination angle is selected.

[0029] In this embodiment, the cross-sections of the first crossbar 10 and the second crossbar 20 are both L-shaped. The L-shaped cross-section requires less material than cross-sections of other shapes (such as circular or square) under the same strength requirements, which can reduce the overall weight of the bracket, facilitate transportation and installation, and have low costs.

[0030] In another example, as Figure 4 shown, the pivotal connection between the second strut 20 and the first strut 10 can also be achieved through the connecting member 300, which helps to reduce the types of assembled parts, further simplifies the bracket structure, and reduces the manufacturing cost.

[0031] In some embodiments, the number of adjustment holes 22 on the second strut 20 is 3 - 5. By providing multiple adjustment holes 22, users can select different hole positions to connect the adjustment rod 30 according to the actual installation environment and lighting conditions, and the number of 3 - 5 adjustment holes 22 can meet the needs of most users.

[0032] Specifically, as Figure 2 shown, the number of adjustment holes 22 on the second strut 20 is 4, and the positions of the adjustment holes 22 are set such that the second strut 20 can form any one of the included angles of 15 degrees, 25 degrees, 35 degrees, and 45 degrees with respect to the first strut 10.

[0033] In this way, the positions of the 4 adjustment holes 22 are set such that the second strut 20 can form four common inclination angles of 15 degrees, 25 degrees, 35 degrees, and 45 degrees with respect to the first strut 10. Users can select the appropriate adjustment hole 22 according to the change of seasons to easily adjust the inclination angle of the photovoltaic module, so that it always maintains the best light-receiving state, thereby improving the power generation efficiency. In addition, if the balcony of the user does not face due south, or there are obstacles such as buildings or trees around, the problem of insufficient light can also be compensated by adjusting the inclination angle of the photovoltaic module, further improving the power generation efficiency.

[0034] In another example, during actual installation between the first strut 10 and the second strut 20, the assembly of the adjustment rod 30 can be cancelled to show an included angle of 0 degrees formed by the second strut 20 with respect to the first strut 10. Assuming that the height of the balcony railing of the user is relatively high and there is no obstruction, in this case, the user can vertically install the photovoltaic module on the balcony so that it can obtain the best sunlight irradiation angle without angle adjustment. Therefore, the user can selectively cancel the assembly of the adjustment rod 30, directly connect the first strut 10 and the second strut 20 to form an included angle of 0 degrees, and it will not affect the power generation efficiency of the photovoltaic module.

[0035] In some embodiments, as Figure 1 and Figure 4As shown, connection ears 400 are provided at one end where the first strut 10 and the second strut 20 are pivotally connected to each other and at both ends of the adjusting rod 30. Each connection ear 400 is provided with a through hole, and the connecting member 300 passes through the through hole to connect the first strut 10, the second strut 20 and the adjusting rod 30 to each other. Specifically, each connection ear 400 is provided with a through hole, and the connecting member 300 (such as a bolt) passes through the through hole on the connection ear 400 to connect the first strut 10, the second strut 20 and the adjusting rod 30 to form a stable triangular structure. Moreover, the connection ear 400 can also make the ends of the rods (10, 20, 30) more rounded, avoiding sharp edges and corners, improving the safety of the bracket, and preventing users from being accidentally injured during installation or use. For example, in some embodiments, the connection ear 400 can be designed as a circle or an ellipse, and the through hole can be provided at the center position of the connection ear 400, so that the ends of the rods can be smoother and potential safety hazards can be reduced.

[0036] In some embodiments, as Figure 1 shown, a hook 23 is fixedly installed at one end of the second strut 20 pivotally connected to the first strut 10, and the opening of the hook 23 faces the position where the adjusting rod 30 is pivotally connected to the second strut 20. With this structural design, users can choose a suitable installation method according to the actual situation and the type of balcony railing. For example, if the shape of the user's balcony railing is special, such as a circular railing, or if the user does not want to drill holes in the wall or railing, the user can choose to directly hang the hook 23 on the second strut 20 on the balcony railing to complete the installation, without using fixing parts such as installation holes 21 and expansion bolts, and without drilling holes in the wall or railing.

[0037] In some embodiments, black coatings are applied to the outer surfaces of the photovoltaic back frame 100, the bracket body 200 and the connecting member 300. Specifically, the black coating can effectively absorb light, reduce light reflection, especially reduce the reflection of sunlight, thereby reducing light pollution, and further improving the visual environment, making the photovoltaic bracket more coordinated with the surrounding environment.

[0038] In some embodiments, as Figure 1 shown, a cross bar 500 is further included, and both ends of the cross bar 500 are fixedly connected to the two second struts 20 respectively. The presence of the cross bar 500 does not affect the angle adjustment function of the bracket. Users can still adjust the tilt angle of the photovoltaic module through the adjusting rod 30 and the adjusting hole 22. Moreover, the cross bar 500 connects the two second struts 20 to form a stable frame structure, which can effectively enhance the overall strength and stability of the bracket, enabling it to withstand greater external forces such as wind force and snow load, and having higher reliability and safety.

[0039] In another example, between the two adjusting rods 30, they can also be connected by a cross bar 500 to form a more stable frame structure. Even when supporting a relatively large-sized photovoltaic module, the strength and stability of the bracket can be effectively ensured.

[0040] In some embodiments, the structure of the first support rod 10 is the same as that of the second support rod 20. In this way, on the one hand, only one set of molds and tooling is required for manufacturing the support rods, without the need to separately design and manufacture molds and tooling for two support rods with different structures, which can significantly reduce the manufacturing cost and maintenance cost of the molds and tooling, thereby reducing the overall manufacturing cost of the product. On the other hand, it can also reduce the types of inventory, lower the difficulty and cost of inventory management, such as reducing the demand for storage space, simplifying the inventory counting process, etc. And during actual assembly, the same support rods can be used interchangeably without distinguishing the installation positions of the first support rod 10 and the second support rod 20, improving the assembly efficiency.

[0041] The photovoltaic balcony bracket provided in this embodiment has the advantages of convenient installation, adjustable angle, high structural strength, beautiful appearance, moderate cost, environmental protection and energy saving, etc. It can effectively solve the deficiencies existing in the balcony photovoltaic bracket technology in the related art, meet the growing demand for balcony photovoltaic applications, and has good popularization and application value.
