Description

Technical Field

[0001] This application relates to the field of photovoltaic panel installation technology, and in particular to folding angle brackets. Background Technology

[0002] A photovoltaic (PV) system is a system that converts solar energy into electrical energy using solar cell modules and other auxiliary equipment. It is generally classified into stand-alone systems, grid-connected systems, and hybrid systems. Since the beginning of the 21st century, the global solar photovoltaic power generation industry has developed rapidly, with its market application scale continuously expanding, and its role in the development of future energy sources becoming increasingly important.

[0003] The power generation efficiency of photovoltaic (PV) panels depends on the effective area for collecting sunlight. Since the angle of sunlight varies, the angle of the PV panels needs to be adjusted to meet the required collection efficiency at different times. However, current angle adjustment devices suffer from poor stability and complex adjustment processes. Therefore, further improvements are needed. Summary of the Invention

[0004] In order to improve the problems of poor stability and complicated adjustment process of existing angle adjustment devices, the purpose of this application is to provide a foldable angle bracket.

[0005] The folding angle bracket provided in this application adopts the following technical solution: A folding angle bracket includes a first connector, a second connector, and a support member. The first connector and the second connector are hinged together. One end of the support member is hinged to the first connector and is located away from the hinge point between the second connector and the first connector. A fixing member is provided on the side of the second connector facing the support member. The fixing member has several limiting holes distributed on it. A reinforcing rod is provided on the other end of the support member. The reinforcing rod abuts against the limiting holes at different front and rear positions, corresponding to different tilt angles of the first connector. Fasteners are connected between the second connector, the support member, and the reinforcing rod.

[0006] By adopting the above technical solution, during use, the photovoltaic panel is installed on the first connector, and the second connector is placed stably on the ground or roof. The reinforcing rod on the support is matched with the limiting port according to the required tilt angle of the photovoltaic panel. The reinforcing rod abuts against the limiting port, and fasteners are inserted through the second connector, the support, and the reinforcing rod, which can comprehensively strengthen the support strength of the support for the photovoltaic panel and the first connector, resulting in high structural stability. At the same time, the process of adjusting the tilt angle of the photovoltaic panel controlled by the support is convenient and quick, and the operation efficiency is fast.

[0007] Optionally, the first connector is provided with two clamping members, which are respectively connected to the left and right ends of the first connector.

[0008] By adopting the above technical solution, the photovoltaic panels can be effectively fixed by using the clamping parts at both ends of the first connector, which facilitates disassembly and installation and makes maintenance convenient.

[0009] Optionally, the reinforcing rod is provided with bosses at both ends, and the support member is provided with through holes for the bosses to engage.

[0010] By adopting the above technical solution and utilizing the boss, the reinforcing rod can be fully engaged in the through hole, making it less likely to fall off and enhancing the stability of the local connection.

[0011] Optionally, numerical scale lines are provided on the side of the limiting port.

[0012] By adopting the above technical solution, numerical scale lines are set on the side of each limiting port to indicate the position distance of the limiting port on the fixing component. During adjustment, the support component can quickly select the limiting port at the corresponding scale line position to abut according to the tilt angle required by the photovoltaic panel, thus achieving rapid overall adjustment.

[0013] Optionally, the second connector is provided with a support member at a position on the same straight line as the limiting port. When the reinforcing rod abuts against the limiting port, the support member abuts against the support member at the same time.

[0014] By adopting the above technical solution and utilizing the support component, when the reinforcing rod abuts against the limiting port, the support component can also abut against the support component at the same time, which enhances the overall support stability and local connection strength of the support component and makes it less prone to shaking; at the same time, the support component can improve the positioning of the reinforcing rod, making it easier for fasteners to be quickly inserted and connected, and improving the installation time.

[0015] Optionally, the fastener includes a screw-lock structure and a latching structure. The screw-lock structure includes a connector and a locking member. The connector passes through the second connector, the support member, and the reinforcing rod. The locking member is threadedly connected to the connector.

[0016] By adopting the above technical solutions, both the screw-lock structure and the latching structure can effectively fix the connection position of the support member on the second connector. When the screw-lock structure is used, the connector passes through the second connector and the reinforcing rod together, so that the three parts are connected together by the connector and fixed by the threaded connection of the locking member. The connection structure is simple and has a good stabilizing effect.

[0017] Optionally, the locking structure includes a telescopic component, a fixed block, a limiting rod, and a limiting member. The second connecting member has a limiting cavity for mounting the fixed block and the telescopic component. The fixed block has a limiting hole for mounting the telescopic component. The limiting member is located on the upper part of the telescopic component and abuts against it. A baffle is provided on the side of the limiting member facing the telescopic component. The baffle is located on the outer periphery of the telescopic component. The limiting rod is rotatably connected to the fixed block.

[0018] By adopting the above technical solution, the limiting component is used to limit the telescopic component and the fixed block, preventing them from disengaging from the limiting cavity. One end of the telescopic component is limited within the limiting hole on the fixed block, and the other end is limited by the baffle on the limiting component to prevent it from coming off. The fixed block can extend and retract vertically under the action of the telescopic component. In the stationary state, the fixed block is located at the bottom end of the limiting cavity under the action of the telescopic component. When a locking structure is adopted, the fixed block slides up and down along the limiting cavity, while simultaneously driving the limiting rod to adjust its height accordingly. The limiting rod can rotate freely along the fixed block.

[0019] Optionally, the support member has a connecting groove near the limiting rod. The connecting groove includes an inlet section, a first limiting section, and a second limiting section. The inlet section, the first limiting section, and the second limiting section are interconnected. The limiting rod can be slidably connected to either the first limiting section or the second limiting section according to the degree of inclination of the support member.

[0020] By adopting the above technical solution, the connecting groove on the support allows the limiting rod to enter through the inlet section during rotation. Based on the angle of inclination formed by the support abutting against the second connecting member, when the inclination angle is small, the limiting rod can be slid to the first limiting section to exert tension on the support and prevent it from detaching. When the inclination angle is large, the limiting rod can be slid to the second limiting section to exert tension on the support. When the inclination angle is large, the structural design of the second limiting section can effectively prevent the limiting rod from detaching from the connecting groove.

[0021] Optionally, the fixing block is further provided with a pull rod for controlling the vertical lifting and sliding of the fixing block along the limiting cavity.

[0022] By adopting the above technical solution, the tie rod can provide powerful driving control for the fixed block, which facilitates indirect control of the free lifting and lowering of the limit rod, allowing the limit rod to slide better into the connecting groove.

[0023] Optionally, at least two brackets are provided.

[0024] By adopting the above technical solution, two brackets can be used to achieve stable support for the photovoltaic panel. When the overall weight of the photovoltaic panel is heavy or the length dimension is large, using multiple brackets to support the installation results in good overall load-bearing capacity.

[0025] In summary, this application includes at least one of the following beneficial effects: 1. The reinforcing rod abuts against the limiting port, and fasteners are inserted through the second connector, the support, and the reinforcing rod. This strengthens the support of the support to the photovoltaic panel and the first connector, resulting in high structural stability. At the same time, the support controls the tilt angle adjustment of the photovoltaic panel, making the process convenient and quick, with high operational efficiency and strong overall practicality. It has great market promotion value. 2. Numerical scale lines are set on the side of each limit port to indicate the position distance of the limit port on the fastener. During adjustment, the support can quickly select the limit port at the corresponding scale line position to abut according to the required tilt angle of the photovoltaic panel, so as to achieve rapid adjustment of the whole. 3. By using the support component, when the reinforcing rod abuts against the limiting port, the support component can also abut against the support component at the same time, which enhances the overall support stability and local connection strength of the support component and makes it less prone to shaking; at the same time, the support component can improve the positioning of the reinforcing rod, making it easier for fasteners to be quickly inserted and connected, and improving the installation time. 4. By utilizing the connecting groove on the support member, the limiting rod enters from the inlet section during rotation. Based on the angle of inclination formed by the support member abutting against the second connecting member, when the inclination angle is small, the limiting rod can be slid to the first limiting section to exert tension on the support member and prevent it from detaching. When the inclination angle is large, the limiting rod can be slid to the second limiting section to exert tension on the support. When the inclination angle is large, the structural design of the second limiting section can effectively prevent the limiting rod from detaching from the connecting groove.

[0028] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail below.

[0029] Example 1: Folding angle bracket, see reference Figure 1 and Figure 2 It includes a first connector 100, a second connector 200, and a support 300. The first connector 100, the second connector 200, and the support 300 are made of metal, preferably stainless steel or aluminum alloy, providing good weight-bearing capacity and resistance to deformation. One end of the first connector 100 is hinged to one end of the second connector 200, and the second connector 200 is located above the first connector 100. One end of the support 300 is hinged to the first connector 100 and is located away from the hinge point between the first connector 100 and the second connector 200. The support 300 can swing freely toward the second connector 200.

[0030] When the other end of the support member 300 abuts against the second connector 200, the first connector 100 is tilted at an angle, and the photovoltaic panel 700 can be installed on the tilted first connector 100. The first connector 100 is provided with two clamping members 110, which are respectively installed at the left and right ends of the first connector 100. The first connector 100 is provided with a round hole or a waist-shaped hole for fixing the clamping members 110. In order to adapt to the fixing of photovoltaic panels 700 of different sizes, in this embodiment, one end of the first connector 100 is provided with a round hole and the other end is provided with a waist-shaped hole. One clamping member 110 is installed in the round hole and fixed by a fastening bolt, and the other clamping member 110 is slidably installed in the waist-shaped hole and fixed by a fastening bolt. The outer periphery of the photovoltaic panel 700 is clamped and fixed by the clamping member 110, which facilitates disassembly and installation and makes maintenance convenient.

[0031] See Figure 3 and Figure 4A fixing member 500 is provided on the side of the second connector 200 facing the support member 300. The fixing member 500 and the second connector 200 are fixedly connected by rivets, resulting in a high structural connection strength. Several limiting holes 510 are distributed on the fixing member 500. The limiting holes 510 are arranged parallel to each other along the straight direction of the fixing member 500. The spacing between each limiting hole 510 is different. A numerical scale line 520 is provided on the side of each limiting hole 510 to indicate the position distance of the limiting hole 510 on the fixing member 500. During adjustment, the support member 300 can quickly select the limiting hole 510 at the corresponding scale line position to abut according to the required tilt angle of the photovoltaic panel 700, thus achieving rapid overall adjustment.

[0032] See Figure 4 A reinforcing rod 400 is provided at one end of the support member 300 that abuts against the second connector 200. The reinforcing rod 400 has outwardly protruding bosses 410 at both ends. The support member 300 has through holes 310 for the bosses 410 to engage with it. The bosses 410 ensure that the reinforcing rod 400 is fully engaged within the through holes 310, preventing it from falling off and enhancing the stability of the local connection. The reinforcing rod 400 abuts against the limiting port 510. During engagement, the appropriate limiting port 510 is selected based on the required tilt angle of the photovoltaic panel 700 for appropriate engagement. After the parts are properly aligned, a fastener 600 is installed between the second connector 200, the support 300, and the reinforcing rod 400. The fastener 600 has a screw-lock structure and includes a connector 610 and a locking member 620. In this embodiment, the connector 610 is a fastening bolt, and the locking member 620 is a fastening nut. The threaded end of the fastening bolt passes through the second connector 200, the support 300, and the reinforcing rod 400. The fastening nut is threadedly connected to the fastening bolt, which is used to strengthen the support strength of the support 300 for the photovoltaic panel 700 and the first connector 100, resulting in high structural stability.

[0033] In order to ensure that the bracket can stably support the photovoltaic panel 700, at least two brackets are provided in this embodiment. When the overall weight of the photovoltaic panel 700 is heavy or the length dimension is large, using two or more brackets to support the installation will improve the overall load-bearing capacity.

[0034] The implementation principle of this application embodiment is as follows: In use, the photovoltaic panel 700 is installed on the first connector 100, and the second connector 200 is placed stably on the ground or roof. The reinforcing rod 400 on the support 300 selects a suitable limiting port 510 for corresponding abutment according to the required tilt installation angle of the photovoltaic panel 700. The reinforcing rod 400 abuts against the limiting port 510, and at the same time, the fasteners 600 are inserted through the second connector 200, the support 300, and the reinforcing rod 400, which can comprehensively strengthen the support strength of the support 300 for the photovoltaic panel 700 and the first connector 100, resulting in high structural stability.

[0035] Example 2: See Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that the second connector 200 is provided with support members 210 on the left and right sides of the limiting port 510 along the same straight line. The support members 210 are welded and fixed to the second connector 200. The support members 210 are set at an angle by two clamping edges, which are adapted to the shape of the bottom end of the support member 300 facing the second connector 200. When the reinforcing rod 400 abuts in the limiting port 510, the end of the support member 300 facing the second connector 200 abuts on the support member 210 at the same time. As the reinforcing rod 400 abuts on the limiting port 510 at different front and rear distances, the included angle of the support member 300 relative to the second connector 200 changes at the same time. The included angle direction of the support member 210 on the side of the limiting port 510 also changes with the tilt angle of the support member 300. By using the support member 210, when the reinforcing rod 400 abuts against the limiting port 510, the support member 300 can also abut against the support member 210 at the same time, which enhances the overall support stability and local connection strength of the support member 300 and makes it less prone to shaking; at the same time, the support member 210 can improve the positioning of the reinforcing rod 400, making it easier for the fastener 600 to be quickly inserted and connected, and improving the installation time.

[0036] The implementation principle of this application embodiment is as follows: when the reinforcing rod 400 on the support member 300 abuts against the corresponding limiting port 510, the end of the support member 300 can also abut against the support member 210 on the side of the corresponding limiting port 510 at the same time, making the overall support member 300 more stable, and at the same time facilitating the quick insertion and connection of the fastener 600.

[0037] Example 2: See Figure 7The difference between this embodiment and Embodiment 1 is that the fastener 600 adopts a locking structure, which includes a telescopic member 630, a fixing block 640, a limiting rod 650, and a limiting member 660. In this embodiment, the telescopic member 630 adopts a telescopic spring. The second connecting member 200 has a limiting cavity 220 on the opposite side away from the support member 210 for installing the fixing block 640 and the telescopic member 630. The limiting cavity 220 is vertically arranged. The top of the fixing block 640 has a limiting hole 641 for installing one end of the telescopic member 630. The fixing block 640 is installed at the bottom of the telescopic member 630. The telescopic member 630 is vertically connected to the limiting hole 641 of the fixing block 640. The limiting member 660 is installed on the upper part of the telescopic member 630, and both ends of the limiting member 660 are connected to the second connecting member 200. The second connecting member 200 forms an overall support. The limiting member 660 is fixed to the second connecting member 200 by fastening screws. A baffle 661 is provided on the bottom side of the limiting member 660 facing the telescopic member 630. The baffle 661 is arc-shaped and located on the outer periphery of the telescopic member 630 to prevent the telescopic member 630 from dislodging from the limiting cavity 220 during compression deformation. The limiting rod 650 is L-shaped and integrally formed from the short side and the long side. The end of the long side is rotatably connected to the fixing block 640. The fixing block 640 can extend and retract vertically under the action of the telescopic member 630. In the stationary state, the fixing block 640 is located at the bottom end of the limiting cavity 220 under the action of the telescopic member 630. When the locking structure is adopted, the fixing block 640 slides up and down along the limiting cavity 220, while driving the limiting rod 650 to adjust its height accordingly. The limiting rod 650 can rotate freely along the fixing block 640.

[0038] The fixed block 640 is provided with a pull rod 642 for controlling the vertical lifting and sliding of the fixed block 640 along the limiting cavity 220. The pull rod 642 can provide a powerful driving control for the fixed block 640, which facilitates the indirect control of the free lifting and lowering of the limiting rod 650, so that the limiting rod 650 can slide better into the connecting groove 320.

[0039] A connecting groove 320 is provided at the end of the support member 300 and near the short side of the limiting rod 650. The connecting groove 320 includes an inlet section 321, a first limiting section 322 and a second limiting section 323. The inlet section 321, the first limiting section 322 and the second limiting section 323 are interconnected and have an overall Y-shaped structure. The short side of the limiting rod 650 can be slidably connected to the corresponding first limiting section 322 or second limiting section 323 according to the connection tilt of the support member 300. Specifically, during rotation, the limiting rod 650 enters through the inlet section 321. Based on the angle of inclination formed by the support member 300 abutting against the second connecting member 200, when the inclination angle is small, the limiting rod 650 can be slid to the first limiting section 322 to exert a pulling force on the support member 300 and prevent the support member 300 from detaching. When the inclination angle is large, the limiting rod 650 can be slid to the second limiting section 323 to exert a pulling force on the support. When the inclination angle is large, the structural design of the second limiting section 323 can effectively prevent the limiting rod 650 from detaching from the connecting groove 320.

[0040] It should be noted that the original screw-lock structure is prone to problems of being difficult to remove and disassemble due to gravity. The fastener 600 adopts a snap-lock structure, which makes it easy to connect and remove the reinforcing rod 400 on the support 300 when it abuts against the limiting port 510, without affecting the limiting effect, and the use effect is good.

[0041] The implementation principle of this application embodiment is as follows: Based on the angle of inclination formed by the support member 300 abutting against the second connector 200, when the inclination angle is small, the limiting rod 650 can be slid to the first limiting segment 322 to achieve a pulling force on the support member 300 and prevent the support member 300 from detaching; when the inclination angle is large, the limiting rod 650 can be slid to the second limiting segment 323 to achieve a pulling force on the support. When the inclination angle is large, the structural design of the second limiting segment 323 can effectively prevent the limiting rod 650 from detaching from the connecting groove 320. The fastener 600 with a locking structure can maintain the limiting effect while facilitating process connection and removal.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
