Description

Technical Field

[0001] This application relates to the field of photovoltaic system technology, and in particular to a connection structure, mounting bracket and photovoltaic system. Background Technology

[0002] In the existing installation brackets, welding is often used between the diagonal braces, columns and main beams during installation. However, the use of welding often leads to long on-site construction time, which is a major factor that seriously affects construction efficiency. Utility Model Content

[0003] The main objective of this application is to propose a connection structure, mounting bracket, and photovoltaic system, which aims to improve the installation efficiency of the mounting bracket.

[0004] To achieve the above objectives, this application proposes a connection structure for connecting a first support member and a second support member. The connection structure includes a base and two connectors. The base is used to connect the first support member, and at least one of the connectors is rotatably connected to the base, so that the connection structure has a first state and a second state. Compared with the first state, the opening between the two connectors is smaller in the second state. In the first state, the space between the two connectors allows the second support member to be inserted. In the second state, the two connectors can clamp the inserted second support member and connect to it.

[0005] In one embodiment, the connecting structure further includes a rotating shaft and a limiting member. The connecting member is rotatably connected to the base via the rotating shaft, and the limiting member is disposed on the base and limits the connection of the connecting member in the second state.

[0006] In one embodiment, the base is provided with a mounting hole, the limiting member is at least partially disposed in the mounting hole, the connector is provided with a limiting hole, and the limiting member is elastically expandable and contractible within the mounting hole, so that the limiting member elastically abuts against the edge of the limiting hole in the first state and is inserted into the limiting hole in the second state.

[0007] In one embodiment, the limiting member includes a limiting part and an elastic part. The limiting part is telescopically disposed in the mounting hole, and the elastic part is disposed in the mounting hole. Under the action of the elastic part, the limiting part can naturally maintain a state of extending out of the mounting hole. When the limiting part retracts into the mounting hole, under the action of the elastic part, the limiting part has a tendency to extend out of the mounting hole.

[0008] In one embodiment, the connection structure further includes an end cap, the mounting hole extending through the base along its axial direction, the end cap being disposed at the end of the elastic portion away from the limiting portion, and sealing the mounting hole.

[0009] In one embodiment, the inner wall of the mounting hole is provided with a first stepped surface facing the elastic part, and the limiting part is provided with a second stepped surface away from the elastic part. In the second state, the first stepped surface abuts against the second stepped surface.

[0010] In one embodiment, the connector is provided with a guide groove communicating with the limiting hole, and the limiting part elastically abuts against the guide groove in the first state. The guide groove is used to guide the limiting member to slide into the limiting hole.

[0011] In one embodiment, the axial direction of the limiting hole is consistent with the axial direction of the rotating shaft, and the guide groove is an arc segment with its center located on the axis of the rotating shaft, and one end of the arc segment is connected to the limiting hole.

[0012] In one embodiment, the connector includes a first connecting portion and a second connecting portion arranged at an angle. The first connecting portion is used to connect to the second support member. The two first connecting portions are arranged opposite to each other, and the two second connecting portions are arranged facing each other between the two first connecting portions. In the first state, the second connecting portion protrudes from the base. When the second support member is inserted into the space between the two connectors, the second support member can push the second connecting portion, so that the connection structure switches from the first state to the second state.

[0013] In one embodiment, the first connecting portion is provided with at least one first connecting hole, which is used to connect the second support member.

[0014] In one embodiment, an anti-slip structure is provided on the opposite side of the two first connecting portions.

[0015] In one embodiment, one of the base and the connector is provided with a clearance notch, and the other is provided at the clearance notch, so that the connector and the base can rotate relative to each other at the clearance notch.

[0016] In one embodiment, the base is provided with at least one second connection hole for connecting the first support member.

[0017] This application also proposes a mounting bracket, including a first support member, a second support member, and the aforementioned connecting structure.

[0018] This application also proposes a photovoltaic system including the aforementioned mounting bracket.

[0019] The technical solution of this application uses at least one connector to rotatably connect to the base, allowing the connection structure to have a first state and a second state. This enables the second support member to be inserted between the two connectors in the first state (with a larger opening) and connected to the connectors in the second state (with a smaller opening), thus achieving rapid installation between the connectors and the second support member. Simultaneously, the base can connect to the first support member, allowing for a secure connection between the first and second support members through the connection structure, eliminating the need for welding. This improves the installation efficiency of the mounting bracket and reduces the safety risks associated with welding. Attached Figure Description

[0035] This application proposes a connection structure 10.

[0036] Please see Figure 1 and Figure 2In one embodiment of this application, the connecting structure 10 is used to connect the first support member 20 and the second support member 30. The connecting structure 10 includes a base 100 and two connectors 200. The base 100 is used to connect the first support member 20. At least one connector 200 is rotatably connected to the base 100 so that the connecting structure 10 has a first state and a second state. Compared with the first state, the opening between the two connectors 200 is smaller in the second state. In the first state, the space between the two connectors 200 can accommodate the insertion of the second support member 30. In the second state, the two connectors 200 can clamp the inserted second support member 30 and connect to the second support member 30.

[0037] Specifically, the base 100 is used to connect the first support member 20, which can be one of a column, a main beam, or a diagonal brace; the connector 200 is used to connect the second support member 30, which can also be one of a column, a main beam, or a diagonal brace, so that the first support member 20 and the second support member 30 can be connected through the connecting structure 10. That is, the connection between the diagonal brace and the column or main beam can be achieved through the connecting structure 10.

[0038] At least one connector 200 is rotatable relative to the base 100, allowing different openings between the two connectors 200, resulting in a first state and a second state for the entire connection structure 10. In the first state, the opening between the two connectors 200 is larger, providing sufficient space for the second support member 30 to be inserted. The second support member 30 can be directly inserted between the two connectors 200, reducing the difficulty of insertion. In the second state, the opening between the two connectors 200 is smaller, clamping the already inserted second support member 30. Further secure connections between the connectors 200 and the second support member 30 can be achieved through fasteners, adhesives, or snap-fits, thus ensuring a strong connection between the first support member 20 and the second support member 30.

[0039] The first support member 20 and the second support member 30 are connected by a connecting structure 10. No welding is required between the two support members, thus reducing construction difficulty, shortening construction time, lowering the installation threshold, and improving installation efficiency. It also avoids the softening and strength reduction of steel caused by repeated welding, preventing fire hazards associated with welding and reducing safety risks. The connecting structure 10 can accommodate various angles between the first support member 20 and the second support member 30, allowing for adjustment of the connection angle or position according to different construction environments, achieving multi-angle fixation. Furthermore, changing the opening by rotating the connecting member 200 is not only simple to operate but also adaptable to second support members 30 of different sizes, improving the applicability of the connecting structure 10.

[0040] The technical solution of this application achieves rapid installation of the connector 200 and the second support 30 by rotatably connecting at least one connector 200 to the base 100, thus allowing the connecting structure 10 to have a first state and a second state. This enables the second support 30 to be inserted between the two connectors 200 in the first state (with a larger opening) and connected to the connectors 200 in the second state (with a smaller opening). Simultaneously, the base 100 can connect to the first support 20, allowing for a secure connection between the first support 20 and the second support 30 via the connecting structure 10, eliminating the need for welding. This improves the installation efficiency of the mounting bracket and reduces the safety risks associated with welding.

[0041] In one implementation, please refer to Figure 3 The connecting structure 10 also includes a rotating shaft 300 and a limiting member 400. The connecting member 200 is rotatably connected to the base 100 through the rotating shaft 300. The limiting member 400 is located on the base 100 and limits the connection of the connecting member 200 in the second state.

[0042] The rotating shaft 300 connects the base 100 and the connector 200 respectively, and the connector 200 can rotate around the axis of the rotating shaft 300, so that the two connectors 200 have different openings in the first state and the second state, and at the same time realize the switching of the connection structure 10 between the first state and the second state. The rotating shaft 300 includes a main body and end parts located at both ends of the main body. It can be that the two end parts are interference-fitted with the base 100, and the connector 200 is located in the main body and can rotate around the main body; or it can be that the two end parts are clearance-fitted with the connector 200, and the main body passes through the base 100 and is interference-fitted with the base 100.

[0043] The function of the limiting member 400 is to restrict the position of the connecting member 200 when the connecting structure 10 is in the second state, preventing it from rotating excessively or loosening. This ensures that the second support member 30 is clamped between the two connecting members 200, improving the stability of the initial connection between the second support member 30 and the two connecting members 200. This facilitates the convenience and stability of further tightening the connection between the second support member 30 and the two connecting members 200. The limiting connection between the limiting member 400 and the connecting member 200 can be a pin hole connection, a magnetic connection, or a snap-fit ​​connection, etc.

[0044] The design of the pivot 300 allows at least one connector 200 to rotate freely, enabling the connection structure 10 to have a first state and / or a second state with different opening degrees. This improves the ease of connection between the second support 30 and the connector 200, adapts to different installation angles and positions of the second support 30, and increases the flexibility of the connection structure 10. The setting of the limiting member 400 ensures that the connector 200 will not move accidentally in the second state, enhancing the stability and safety of the connection structure 10.

[0045] In other embodiments, the pivot 300 may also be a shaft protrusion disposed on the base 100; or the base 100 and the connector 200 may be rotatably connected by a hinge.

[0046] In one implementation, please refer to Figure 4 , Figure 6 and Figure 7 The base 100 is provided with a mounting hole 120, and the limiting member 400 is at least partially provided in the mounting hole 120. The connector 200 is provided with a limiting hole 221. The limiting member 400 can elastically extend and retract within the mounting hole 120 so that the limiting member 400 elastically abuts against the edge of the limiting hole 221 in the first state and is inserted into the limiting hole 221 in the second state.

[0047] The base 100 has a mounting hole 120 for accommodating the limiting member 400. The axis of the mounting hole 120 can be parallel to or intersect with the axis of the rotating shaft 300. The mounting hole 120 provides a guiding function to ensure the accurate movement direction of the limiting member 400, allowing the limiting member 400 to freely extend and retract within the mounting hole 120. The limiting member 400 can be a protrusion, pin, or ball bearing with a spring or other elastic element.

[0048] The connector 200 is provided with a limiting hole 221. In the second state, the position and shape of the limiting hole 221 match that of the limiting member 400, so that the limiting member 400 can be smoothly inserted into the limiting hole 221 when the connecting structure 10 is in the second state. In the first state, the limiting hole 221 is positioned at a certain distance from the limiting member 400, and the limiting member 400 elastically abuts against the edge of the limiting hole 221. The limiting member 400 can apply a certain preload to the connector 200 to prevent the connector 200 from rotating arbitrarily in the first state. When a certain force is applied to the connector 200 to make it rotate, the connecting structure 10 can switch from the first state to the second state. During this process, the limiting member 400 slides into the limiting hole 221 along the area outside the edge of the limiting hole 221 to lock the position of the connector 200 and prevent it from loosening. The elastic extension and retraction design of the limiting member 400 allows the connecting structure 10 to automatically lock in the second state without additional operation steps, improving the ease of use of the connecting structure 10.

[0049] In one implementation, please refer to Figure 4 , Figure 6 and Figure 7 The limiting member 400 includes a limiting part 410 and an elastic part 420. The limiting part 410 is telescopically disposed in the mounting hole 120, and the elastic part 420 is disposed inside the mounting hole 120. Under the action of the elastic part 420, the limiting part 410 can naturally maintain the state of extending out of the mounting hole 120. When the limiting part 410 retracts into the mounting hole 120, under the action of the elastic part 420, the limiting part 410 has a tendency to extend out of the mounting hole 120.

[0050] In the first state, part of the limiting part 410 retracts into the mounting hole 120, and part abuts against the edge of the limiting hole 221 of the connector 200, preventing the connector 200 from rotating freely. Under the action of the elastic part 420, the limiting part 410 tends to extend out of the mounting hole 120. When the connector 200 rotates to the appropriate position, the limiting hole 221 aligns with the limiting part 410, and the edge of the limiting hole 221 no longer restricts the limiting part 410. Under the action of the elastic part 420, the limiting part 410 naturally extends out of the mounting hole 120 and automatically inserts into the limiting hole 221. The limiting part 410 is locked by the limiting hole 221, and the connector 200 is locked and can no longer rotate freely, thereby completing the limiting and fixing of the second support member 30. The end of the limiting part 410 facing the connector 200 is approximately conical or hemispherical so that the limiting part 410 can be more easily inserted into the limiting hole 221.

[0051] In one implementation, please refer to Figure 3 and Figure 4 The connecting structure 10 also includes an end cap 500, and a mounting hole 120 passes through the base 100 along its axial direction. The end cap 500 is located at the end of the elastic part 420 away from the limiting part 410 and blocks the mounting hole 120.

[0052] The mounting hole 120 extends through the base 100 along its axial direction. The limiting member 400 can be inserted from one end of the mounting hole 120 and elastically extend and retract from the other end, thereby reducing the installation difficulty of the limiting member 400. The end cap 500 is located at the end of the elastic part 420 away from the limiting part 410. That is, the end cap 500 seals the end of the mounting hole 120 used for inserting the limiting member 400 to prevent the elastic part 420 and the limiting part 410 from falling out of the mounting hole 120, ensuring the stability and reliability of the limiting member 400. At the same time, it can also prevent the mounting hole 120 from being exposed, thereby improving the appearance of the connection structure 10. The end cap 500 can be a rubber plug, at least partially extending into the mounting hole 120; the end cap 500 can also be generally plate-shaped and directly cover the outside of the mounting hole 120.

[0053] In other embodiments, a groove can be provided on the upper surface of the base 100, the groove communicating with the mounting hole 120, the limiting member 400 being able to be inserted into the mounting hole 120 from the groove, and the end cap 500 covering the opening of the groove.

[0054] In one implementation, please refer to Figure 8 The inner wall of the mounting hole 120 is provided with a first stepped surface facing the elastic part, and the limiting part 410 is provided with a second stepped surface away from the elastic part. In the second state, the first stepped surface and the second stepped surface abut against each other.

[0055] In the first state, the limiting part 410 retracts into the mounting hole 120, the elastic part 420 is compressed, and a gap is formed between the first step surface and the second step surface. In the second state, under the action of the elastic part 420, the limiting part 410 can naturally extend out of the mounting hole 120, and the second step surface of the limiting part 410 abuts against the first step surface of the inner wall of the mounting hole 120, preventing the limiting part 410 from coming out of the mounting hole 120 due to excessive elastic force of the elastic part 420, thereby improving the stability and reliability of the connection between the limiting member 400 and the mounting hole 120.

[0056] In one implementation, please refer to Figure 5 and Figure 7 The connector 200 is provided with a guide groove 222 that communicates with the limiting hole 221. The limiting part 410 elastically abuts against the guide groove 222 in the first state. The guide groove 222 is used to guide the limiting part 400 to slide into the limiting hole 221.

[0057] The guide groove 222 provides a clear movement path for the limiting member 400, ensuring that the limiting member 400 moves accurately along the preset path and preventing the limiting member 400 from shifting or getting stuck during the rotation of the connecting member 200, so that the limiting member 400 can smoothly slide into the limiting hole 221. The guide groove 222 can be a groove with a movement path or a wedge-shaped structure.

[0058] In one implementation, please refer to Figure 5 and Figure 7 The axial direction of the limiting hole 221 is consistent with the axial direction of the rotating shaft 300. The guide groove 222 is an arc segment with its center located on the axis of the rotating shaft 300, and one end of the arc segment is connected to the limiting hole 221.

[0059] When the connector 200 rotates around the axis of the shaft 300, a point mass on the axis of the limiting hole 221 also rotates around the axis of the shaft 300, and its motion trajectory is circular. Correspondingly, the motion trajectory of the limiting member 400 relative to the limiting hole 221 is a part of this circle. The shape of the guide groove 222 coincides with the motion trajectory of the limiting hole 221, that is, it is adapted to the relative motion trajectory of the limiting member 400, so that the limiting member 400 can slide into the limiting hole 221 along the guide groove 222.

[0060] In one implementation, please refer to Figure 2 , Figure 3 and Figure 5 The connector 200 includes a first connecting portion 210 and a second connecting portion 220 arranged at an angle. The first connecting portion 210 is used to connect the second support member 30. The two first connecting portions 210 are arranged opposite to each other, and the two second connecting portions 220 are arranged facing each other between the two first connecting portions 210. In the first state, the second connecting portion 220 protrudes from the base 100. When the second support member 30 is inserted into the space between the two connectors 200, the second support member 30 can push the second connecting portion 220, so that the connection structure 10 switches from the first state to the second state.

[0061] The first connecting portion 210 and the second connecting portion 220 are set at an angle. In the first state, the first connecting portion 210 naturally tilts outward to form an open shape, and the second connecting portion 220 partially protrudes from the base 100. Depending on the required connection angle, the second support member 30 is pre-cut at a corresponding angle to form a cut surface that fits against the base 100. When the second support member 30 is inserted into the space between the two connecting members 200, the cut surface of the second support member 30 first contacts the portion of the second connecting portion 220 protruding from the base 100. As the second support member 30 continues to press down, the connecting member 200 automatically rotates, and the limiting member 400 slides relative to the guide groove 222 until the second connecting portion 220 is level with the base 100, at which point the first connecting member 200 clamps the second support member 30. After the connecting member 200 rotates into position, the limiting member 400 slides into the limiting hole 221 to limit the connecting member 200, thus completing the switch from the first state to the second state. During the process of inserting the second support member 30 into the space between the two connectors 200, the connector 200 is automatically rotated and the limiting member 400 is automatically locked to the limiting hole 221. There is no need to manually rotate the connector 200 or manually lock the limiting member 400 to the limiting hole 221, thereby further improving the installation efficiency of the first support member 20 and the second support member 30.

[0062] In one implementation, please refer to Figure 5 The first connecting part 210 is provided with at least one first connecting hole 211, which is used to connect the second support member 30.

[0063] In the second state, the two first connecting parts 210 clamp the second support member 30, and the fastener passes through the first connecting hole 211 to achieve a tight connection between the first connecting part 210 and the second support member 30. One, two, or more first connecting holes 211 can be provided. When multiple first connecting holes 211 are provided, they are spaced apart along the length of the first support member 20. When the second support member 30 is inclined, each first connecting hole 211 can connect to the second support member 30 at the corresponding angle.

[0064] In other embodiments, the first connecting part 210 and the second support member 30 can also be connected by snap-fit, adhesive, magnetic connection or other means.

[0065] In one implementation, please refer to Figure 5 An anti-slip structure 212 is provided on one side of the two first connecting parts 210 facing each other.

[0066] By providing an anti-slip structure 212 on one side of the two first connecting parts 210 opposite to each other, the friction between the first connecting parts 210 and the second support member 30 can be increased, thus providing initial fixation. The anti-slip structure 212 can be made by machining fine grooves or scratches on the surface of the first connecting parts 210 to increase surface roughness; or by pressing various patterns, such as dots, lines, grids, etc., onto the surface of the first connecting parts 210 to increase friction; or by using high-pressure airflow to spray sand particles to roughen the surface of the first connecting parts 210; or by coating the surface of the first connecting parts 210 with a coating containing anti-slip particles, such as epoxy resin, polyurethane, etc.; or by embedding or adhering fine anti-slip particles, such as quartz sand, ceramic particles, etc., into the surface of the first connecting parts 210; or by creating a series of raised dots on the surface of the first connecting parts 210, or by machining parallel or intersecting raised strips, or by forming wavy raised areas, to increase the contact area and friction between the first connecting parts 210 and the second support member 30.

[0067] In one implementation, please refer to Figure 4 The base 100 has clearance notches 130 on opposite sides. Two connectors 200 are respectively located in the two clearance notches 130. The two ends of the rotating shaft 300 are respectively connected to the opposite sides of the clearance notches 130. The main body of the rotating shaft 300 passes through the connectors 200, so that the connectors 200 can rotate around the rotating shaft 300 at the clearance notches 130.

[0068] In another embodiment, the connector 200 is provided with a clearance notch 130, and the two opposite sides of the base 100 are respectively provided in the two clearance notches 130. The two ends of the rotating shaft 300 are respectively connected to the connector 200, and the main body of the rotating shaft 300 passes through the base 100.

[0069] In one implementation, please refer to Figure 4 The base 100 is provided with at least one second connection hole 110, which is used to connect the first support member 20.

[0070] Fasteners pass through the second connecting hole 110 to securely connect the base 100 to the first support member 20. One, two, or more second connecting holes 110 can be provided. Providing multiple second connecting holes 110 can improve the stability of the connection between the base 100 and the first support member 20.

[0071] Furthermore, the second connecting hole 110 can be configured as a countersunk hole. Correspondingly, the fastener is configured as a countersunk self-tapping screw. The shape of the countersunk hole matches the head of the countersunk self-tapping screw to ensure that the head of the countersunk self-tapping screw can be recessed into the countersunk hole after tightening, so as to be flush with or slightly lower than the surface of the base 100, avoiding the situation where the screw head protrudes and interferes with the second support member 30.
