Description

[Technical Field]

[0001] The present invention relates to a solar panel bracket, and more particularly to a movable solar panel bracket that can adjust the angle of a solar panel and achieve sun tracking functions. [Background technology]

[0002] Solar panels are a key component of photovoltaic power generation systems, converting solar radiation into electrical energy. Traditional solar panels are usually mounted at a fixed angle, meaning they cannot adjust their angle to follow the changing position of the sun. To improve energy conversion efficiency, solar tracking solar panels were developed. Solar tracking solar panels have the ability to adjust their angle based on the changing position of the sun, maximizing solar energy capture and increasing energy conversion efficiency. Summary of the Invention [Problem to be solved by the invention]

[0003] However, solar tracking solar panels face several challenges. First, their structure is complex, resulting in high design and manufacturing costs. To achieve the angle adjustment function, solar tracking solar panels require special mechanisms and control systems, which increase costs and technical requirements. Second, the robustness of solar tracking solar panels is an issue. Due to their movable structure, solar tracking solar panels often lack stability when faced with wind and other external forces. This can lead to damage and reduced efficiency, so more measures are needed to support and protect the structure.

[0004] To summarize the above, conventional solar panels cannot adjust their angle based on the position of the sun, which is why sun-tracking solar panels were developed. However, sun-tracking solar panels have to solve the problems of complex structure and robustness. Therefore, developing a sun-tracking solar panel with a simplified structure and high robustness has great research value and future application prospects.

[0005] Therefore, the present inventors believed that the above drawbacks could be improved, and as a result of extensive research, they came up with the proposal of the present invention, which effectively improves the above problems through rational design.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bracket for a solar panel. [Means for solving the problem]

[0007] In order to solve the above problems, one aspect of the present invention provides a solar panel bracket comprising: an upright ball base; a movable frame including a horizontal bar, the movable frame pivoted to the upright ball base around the horizontal bar; a reinforcing bracket set straddling the horizontal bar and having two fixed ends fixed to the rear side of the movable frame; a positioning base having a first end and a second end, the positioning base being fixed to the horizontal bar by the first end; and a linear actuator having one end pivoted to the upright ball base and the other end pivoted to the second end of the positioning base. When the linear actuator is activated, the movable frame pivots relative to the upright ball base.

[0008] In a preferred embodiment of the invention, the second end of the positioning table is fixed to the movable frame so that, when the linear actuator is actuated, the positioning table drives the movable frame to pivot relative to the upright ball base.

[0009] In a preferred embodiment of the present invention, the cross bar is a polygonal pillar, and the first end of the positioning base is shaped to fit the cross bar, thereby further solidly connecting the cross bar and the positioning base.

[0010] In a preferred embodiment of the present invention, the upright ball base, the positioning platform, and the linear actuator are coplanar, thereby allowing the solar panel bracket to achieve a stable sun tracking effect in a single axis.

[0011] In a preferred embodiment of the present invention, the two sides of the movable frame are defined as the back side and the front side, respectively. The horizontal bar, the upright ball base, the positioning table, and the linear actuator are all located on the back side, and the solar panel is attached to the front side of the movable frame. This prevents any influence on the power generation efficiency of the solar panel located on the front side.

[0012] In a preferred embodiment of the present invention, a reinforcing portion is provided between the two fixed ends of the reinforcing bracket set, the reinforcing portion is straddling the cross bar so as to be attached thereto, and the ends of the reinforcing portion are fixed to the movable frame, with portions of the two fixed ends being fixed to contact the movable frame, and the ends of the two fixed ends being bent away from the movable frame.

[0013] In a preferred embodiment of the present invention, the upright ball base is defined to have a first length, the positioning table is defined to have a second length, and the linear actuator is defined to have a third length, and the sum of any two of the first length, second length, and third length is greater than the remaining one.

[0014] In a preferred embodiment of the present invention, the upright ball base is provided with a bearing, and the cross bar extends through the bearing to allow the movable frame to pivot relative to the upright ball base.

[0015] In a preferred embodiment of the present invention, the linear actuator includes a motor and an extension member. When the linear actuator is operated, the motor drives the extension member to extend or retract along one direction, thereby extending or retracting the length of both ends of the linear actuator. [Effects of the Invention]

[0016] The present invention is configured as described above and therefore provides the following effects. According to one aspect of the present invention, the solar panel bracket pivots relative to the base to track the sun and increase power generation efficiency. According to another aspect of the present invention, the solar panel bracket has a simplified structure and is highly robust. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0018] The following describes embodiments of the solar panel bracket of the present invention with reference to the drawings, but the present invention is not limited to these embodiments, and the members, materials, etc. described below can be modified in various ways within the scope of the present invention. Note that the same or corresponding parts in the drawings are designated by the same reference numerals, and their description will not be repeated.

[0019] 1 is a perspective view showing an exterior of a solar panel bracket according to an embodiment of the present invention. The solar panel bracket includes a movable frame 200 and at least one support set 300.

[0020] The movable frame 200 includes an outer frame 210 and horizontal rods 220. The outer frame 210 is used to secure the solar panel 900. In this embodiment, the entire outer frame 210 has a rectangular frame structure, and two horizontal rods 211 and three vertical rods 212 are fixed to cross each other. The gaps between the two horizontal rods 211 and the three vertical rods 212 are equal. However, the present invention is not limited to this. It is within the scope of the outer frame 210 of this concept for a person skilled in the art to modify the arrangement of the horizontal rods 211 and the vertical rods 212 in the outer frame 210 according to actual needs to secure the solar panel 900. In this embodiment, the horizontal rods 211 and the vertical rods 212 are fixed by a locking method, but the present invention is not limited to this and they may also be fixed by a welding method.

[0021] The horizontal bar 220 is fixed between two horizontal rods 211, the gaps between the two horizontal rods 211 of the horizontal bar 220 are uniform, and the horizontal bar 220 is locked to the three vertical rods 212, but the present invention is not limited thereto, and the horizontal bar 220 may be fixed to the three vertical rods 212 by welding. In this embodiment, the solar panel 900 is locked to the vertical rods 212.

[0022] The solar panel bracket is installed by at least one support set 300. In this embodiment, the solar panel bracket has two support sets 300. However, the present invention is not limited to this, and the number of support sets 300 is at least one, and they are installed at the center position of the cross bar 220. The number of support sets 300 can be changed as needed, and the installation position can also be adjusted. It is only necessary to install them evenly on the cross bar 220. The entire outer frame 210 is rigid, and it is within the scope of this concept to allow the outer frame 210 to pivot relative to the support set 300 around the cross bar 220 as an axis.

[0023] The two sides of the movable frame 200 are defined as the back side and the front side, respectively. The solar panel 900 is attached to the front side of the movable frame 200 to receive sunlight and generate electricity. The support set 300 is installed on the back side of the movable frame 200 and can track the sun without being affected by the movement of the solar panel 900.

[0024] 2, each support set 300 includes an upright ball base 310, a positioning table 320, and a linear actuator 330. The upright ball base 310 has a first length L1, the positioning table 320 has a second length L2, and the linear actuator 330 has a third length L3. The sum of any two of the first length L1, the second length L2, and the third length L3 is greater than the remaining one.

[0025] One end of the upright ball base 310 is fixed to the ground as a base end, for example, by a screw stake, but the present invention is not limited to this. The other end of the upright ball base 310 is used to install the movable frame 200, and the movable frame 200 is pivotally mounted to the plurality of upright ball bases 310 around a cross bar 220. In this embodiment, a bearing 311 is fixed to the other end of the upright ball base 310, and the cross bar 220 of the movable frame 200 penetrates through the bearing 311 and is coaxial with the bearing 311, so that the movable frame 200 is pivotally mounted to the upright ball base 310 around the cross bar 220, but the present invention is not limited to this.

[0026] The positioning table 320 is fixed to the horizontal bar 220. More specifically, the positioning table 320 has a first end 321 and a second end 322, and the first end 321 of the positioning table 320 is fixed to the horizontal bar 220. Optionally, the second end 322 of the positioning table 320 is also fixed to the movable frame 200. In this embodiment, the first end 321 of the positioning table 320 is screwed to the horizontal bar 220 by a joint 323. However, the present invention is not limited to this, and it is within the scope of the present invention to drive the horizontal bar 220 to pivot relative to the upright ball base 310 when the positioning table 320 operates. For example, the first end 321 of the positioning table 320 is fixed to the horizontal bar 220 by welding. In another embodiment, the first end 321 of the positioning table 320 is integrally formed with the horizontal bar 220. In yet another embodiment, the first end of the positioning table 320 has a shape that fits to the cross bar 220, i.e., the cross bar 220 is a polygonal prism, for example a rectangular prism, and the first end 321 of the positioning table 320 has a shape that fits to the rectangular prism, so that when the positioning table 320 moves, the positioning table 320 fits to the cross bar 220, thereby driving the cross bar 220 to pivot relative to the upright ball base 310.

[0027] One end of the linear actuator 330 is pivotally mounted to the upright ball base 310, and the other end is pivotally mounted to the second end 322 of the positioning table 320. The linear actuator 330 includes a motor 331 and an extension member 332. When the linear actuator 330 is operated, the motor 331 drives the extension member 332 to extend or shorten in one direction, thereby extending or shortening the lengths of both ends of the linear actuator 330, thereby pivoting the movable frame 200 relative to the upright ball base 310.

[0028] 2 and 3, one end of linear actuator 330 is pivotally coupled to a fixed position on upright ball base 310, and the other end of linear actuator 330 is pivotally engaged to second end 322 of positioning table 320 by one end of motor 331. In this manner, when motor 331 is operated to extend extension member 332, the other end of linear actuator 330 pushes positioning table 320 so as to pivot relative to cross bar 220, since one end of linear actuator 330 is pivotally attached to a fixed position on upright ball base 310 (see FIG. 2). Conversely, when motor 331 is operated to shorten extension member 332, the other end of linear actuator 330 pivots to pull positioning table 320 in the other direction relative to cross bar 220, since one end of linear actuator 330 is pivotally attached to a fixed position on upright ball base 310 (see FIG. 3). In this way, the movable frame 200 is modified along with the angle of the solar panel 900 to achieve a sun tracking effect.

[0029] It should also be noted that in this embodiment, when the movable frame 200 pivots relative to the upright ball base 310 via the cross bar 220, it only pivots in one direction. Therefore, in the present disclosure, the upright ball base 310, the positioning platform 320, and the linear actuator 330 are designed to be coplanar, so that when the movable frame 200 pivots relative to the upright ball base 310 via the cross bar 220, it does not rotate or shift in other directions, making it more rigid and achieving the effect of a solar panel tracking the sun with a simple structure. That is, although the movable frame 200 of the present disclosure can only change its angle in a single direction and cannot change its angle in multiple axes, it still achieves the effect of a sun-tracking solar panel with such a simple and robust structure.

[0030] In addition, in this embodiment, the solar panel bracket further includes a plurality of reinforcing bracket sets 350 to further strengthen the movable frame 200 and the horizontal bar 220 as a whole and prevent damage due to strong winds. More specifically, each reinforcing bracket set 350 includes two fixed ends 351. The reinforcing bracket set 350 straddles the horizontal bar 220 and is installed along the vertical rod 212. The reinforcing bracket set 350 is fixed to the rear side of the movable frame 200 and is fixed to the vertical rod 212 by the two fixed ends 351. In this embodiment, there are three reinforcing bracket sets 350, each corresponding to one of the three vertical rods 212. However, this is not intended to limit the present invention, and the number of reinforcing bracket sets 350 can be increased or decreased according to actual needs. For example, the number of reinforcing bracket sets 350 may be less than the number of vertical rods 212, as long as structural stability is maintained and cost is taken into consideration.

[0031] Furthermore, in this embodiment, the reinforcing bracket set 350 is fixed to the vertical rod 212 by a screw method, but the present invention is not limited to this, and the reinforcing bracket set 350 may also be fixed to the vertical rod 212 by a welding method. Between the two fixed ends 351 of the reinforcing bracket set 350 is a reinforcing portion 352, which is straddled and attached to the horizontal bar 220, and portions of the two fixed ends 351 are fixed so as to contact the movable frame 200. In this embodiment, the two fixed ends 351 are fixed to the vertical rod 212 by a screw method, but the present invention is not limited to this, and the reinforcing portion 352 may also be fixed to the vertical rod 212 by a welding method. Furthermore, the ends of the two fixed ends 351 may be bent and separated from the movable frame 200, and then screwed to be fixed to the vertical rod 212, and the bent ends can be used as locks to assist positioning when installing the reinforcing bracket set 350. Incidentally, the reinforcing portion 352 strengthens the horizontal bar 220 and the vertical rod 212 of the movable frame 200, but the reinforcing portion 352 is not locked to the horizontal bar 220 but is fixed to the vertical rod 212, and the reinforcing portion 352 is simply straddled by the horizontal bar 220 so as to be attached thereto, which makes the structure strong and simple at the same time.

[0032] In another embodiment, the support set 300 and the reinforcing bracket set 350 are only one unit, and the installation of the reinforcing bracket set 350 increases the overall rigidity of the solar panel bracket. When the linear actuator 330 is actuated to pivot the movable frame 200 relative to the upright ball base 310, the installation of the reinforcing bracket set 350 allows the movable frame 200 to rotate smoothly and prevents bending of the solar panel 900. The installation of the reinforcing bracket set 350 not only reduces the number of linear actuators 330 and reduces costs, but also maintains the performance of the solar panel bracket and ensures the movable frame 200 to rotate smoothly.

[0033] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Explanation of symbols]
