[0072] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0073] The principle of the mounting bracket 10 proposed in this application will be explained in detail below:

[0074] Among related technologies, photovoltaic systems are widely used. Residential photovoltaic systems are often installed in areas such as balconies or rooftops. Different families have different sunlight conditions, and the corresponding suitable angles are also different. Existing photovoltaic system mounting brackets are not easy to install in some scenarios, and the angle is not easy to adjust after installation, resulting in poor power generation efficiency.

[0075] To solve this technical problem, this application provides a mounting bracket 10, as described below. Figures 1-16 Description of mounting bracket 10 according to an embodiment of this application.

[0076] like Figures 1-3 and Figure 14 As shown, the mounting bracket 10 of this application embodiment is applied to a photovoltaic system 1 and includes: a mounting frame 100, an adjusting beam 200, a diagonal brace 400, and a clamp 500.

[0077] Mounting bracket 100 can be made of materials such as steel, aluminum alloy or composite materials.

[0078] In this embodiment, the mounting bracket 100 can be made of aluminum alloy. The mounting bracket 100 made of aluminum alloy is lightweight, easy to handle, and has good corrosion resistance.

[0079] like Figure 3 and Figure 4As shown, the mounting bracket 100 has a sliding portion 110.

[0080] like Figure 3 As shown, the sliding part 110 extends along the first direction z1.

[0081] In this embodiment, the first direction z1 is the height direction of the mounting bracket 100.

[0082] like Figures 2-4 and Figure 15 As shown, the adjusting beam 200 is movably assembled to the sliding part 110 along the first direction z1 via the first connecting piece 300.

[0083] The first connecting member 300 can be a screw, bolt, or pin.

[0084] In this embodiment, the first connector 300 can be a bolt, which has high connection strength and is easy to disassemble.

[0085] The adjusting beam 200 can be made of materials such as steel, aluminum alloy or composite materials.

[0086] In this embodiment, the adjusting beam 200 can be made of aluminum alloy, which is lightweight and has high strength.

[0087] In this embodiment, the first connector 300 is slidably mounted on the sliding part 110 of the mounting bracket 100, and the first connector 300 passes through the sliding part 110 and is connected to the adjusting beam 200. The adjusting beam 200 moves along the first direction z1, and the first connector 300 slides in the sliding part 110 along the first direction z1. After the photovoltaic module 20 is adjusted to a suitable angle, the first connector 300 and the adjusting beam 200 are locked.

[0088] like Figure 3 As shown, the diagonal brace 400 is connected to the first connector 300.

[0089] Understandably, the adjusting beam 200 and the diagonal brace 400 are hinged to the same position on the mounting bracket 100 via the first connector 300.

[0090] The 400 diagonal brace can be made of materials such as steel, aluminum alloy or composite materials.

[0091] In this embodiment, the diagonal brace 400 can be made of aluminum alloy. The diagonal brace 400 made of aluminum alloy is lightweight and easy to process, and it fits well with the mounting frame 100 and the first connector 300.

[0092] Mounting bracket 100 and diagonal brace 400 are used to connect to photovoltaic module 20 of photovoltaic system 1.

[0093] In this embodiment, a support rod may be provided at the upper end of the mounting bracket 100. The support rod may include, but is not limited to, the following forms:

[0094] Firstly, one end of the support rod is hinged to the mounting bracket 100, and the other end of the support rod is fixedly connected to the photovoltaic module 20.

[0095] In this embodiment, one end of the diagonal brace 400 is fixedly connected to the photovoltaic module 20, and the other end is fixedly connected or hinged to the first connecting member 300. First, the support rod is rotated around the rotation axis of the mounting frame 100, and then the adjusting beam 200 is adjusted along the first direction z1 to move the diagonal brace 400 connected to the first connecting member 300. After adjusting the positions of the support rod and the diagonal brace 400, the photovoltaic module 20 is installed, completing the angle adjustment. Alternatively, one end of the support rod is fixedly connected to the mounting frame 100, and the other end of the support rod is hinged to the photovoltaic module 20.

[0096] In this embodiment, one end of the diagonal brace 400 is hinged to the photovoltaic module 20, and the other end is hinged to the first connector 300. The photovoltaic module 20 is first installed on the support rod and the diagonal brace 400. By adjusting the adjusting beam 200 along the first direction z1, the diagonal brace 400 hinged to the first connector 300 is moved, and the photovoltaic module 20 rotates along the rotation axis of the support rod and the rotation axis of the diagonal brace 400 to complete the angle adjustment.

[0097] The connection methods between the mounting bracket 100 and the diagonal brace 400 and the photovoltaic module 20 of the photovoltaic system 1 include, but are not limited to, the above situations.

[0098] like Figures 2-4 As shown, the clamp 500 is mounted on the mounting frame 100, and the clamp 500 and the mounting frame 100 form a snap-fit ​​groove 600, which is used to snap-fit ​​with the installation scene.

[0099] In this embodiment, the installation scenario can be a balcony concrete wall. One end of the clamp 500 is connected to the mounting frame 100, and a snap-fit ​​groove 600 is formed between the clamp 500 and the mounting frame 100. The snap-fit ​​groove 600 is snapped into two opposite side walls of the concrete wall.

[0100] In related technologies, after selecting the angle between the diagonal brace and the mounting frame of the photovoltaic system's mounting bracket, they are connected by special connectors. These special connectors are mostly used to connect smaller components such as balcony railings, but are not suitable for larger components such as balcony concrete walls. Furthermore, the angle of the mounting bracket is fixed and difficult to adjust. During the initial assembly, it may not be adjusted properly, and with subsequent seasonal changes, the diagonal brace needs to be disassembled and the installation position of the diagonal brace and mounting frame needs to be adjusted. This inconvenience affects the power generation efficiency of the photovoltaic system and makes it difficult to store and use.

[0101] In this embodiment, the mounting bracket 10 has a sliding portion 110 extending along a first direction z1. A first connecting member 300 is slidably assembled with the sliding portion 110. One end of the first connecting member 300 passes through the mounting bracket 100 and is connected to the adjusting beam 200. One end of the diagonal brace 400 is hinged to the first connecting member 300, and the other end of the diagonal brace 400 is hinged to the photovoltaic module 20. A clamp 500 is also installed on the side of the mounting bracket 100 opposite to the photovoltaic module 20. A snap-fit ​​groove 600 is formed between the clamp 500 and the mounting bracket 100. The snap-fit ​​groove 600 snaps into the installation environment (such as a balcony cement wall), providing a stable connection. The mounting bracket 100 is not easily shaken and has good stability. No drilling or structural damage is required at the installation site, allowing for quick installation. When changes in lighting conditions necessitate adjusting the tilt angle of the photovoltaic module 20, pushing the adjusting beam 200 causes the first connector 300 to move within the sliding part 110. The diagonal brace 400, hinged to the first connector 300, rotates around the first connector 300, causing the photovoltaic module 20, hinged to the other end of the diagonal brace 400, to rotate simultaneously around the rotation axis. Locking the first connector 300 completes the angle adjustment of the photovoltaic module 20. Simply pushing the adjusting beam 200 is sufficient to adjust the angle of the photovoltaic module 20. Users can also adjust the angle themselves during seasonal changes. The operation is simple and convenient.

[0102] According to the mounting bracket 10 provided in the embodiments of this application, by setting a clamp 500 on the mounting bracket 100, the mounting bracket 100 can be installed in installation scenarios with large connected components, with a stable connection and good stability. The clamp 500 is snapped into the installation scenario, making operation simple and installation efficiency high. At the same time, by designing the assembly method of adjusting the crossbeam 200, the diagonal brace 400 and the mounting bracket 100, the angle adjustment process of the mounting bracket 10 can be greatly simplified, so as to help the photovoltaic system 1 adjust the solar tracking angle more accurately and improve the power generation efficiency of the photovoltaic system 1.

[0103] In some embodiments, such as Figures 4-8 As shown, the clamp 500 may include a bent portion 510 and a horizontal portion 520.

[0104] The bent portion 510 is connected to the mounting bracket 100 via the horizontal portion 520, and the bent portion 510 and the mounting bracket 100 form a snap-fit ​​groove 600.

[0105] like Figure 5 As shown, in this embodiment, the bending portion 510 includes a first portion 514 and a second portion 515 in a 90° vertical state. The first portion 514 is connected to the horizontal portion 520. The end of the horizontal portion 520 away from the bending portion 510 is connected to the mounting bracket 100. The second portion 515 forms a snap-fit ​​groove 600 with the mounting bracket 100.

[0106] The first part 514 and the second part 515 can be integrally formed, or they can be connected by riveting, bolting or other connection methods.

[0107] It should be noted that when the installation scenario only involves a cement wall, the snap-fit ​​groove 600 can be directly snapped into the cement wall. When the installation scenario involves a cement wall with metal railings, the horizontal part 520 connects to the bent part 510 through the gap between the metal railings and the cement wall, forming the snap-fit ​​groove 600 that snaps into the cement wall.

[0108] The mounting bracket 10 provided in the embodiments of this application has a structure of clamp 500 to adapt to different types of installation scenarios, and has good versatility.

[0109] In some embodiments, the mounting bracket 10 may also include a second connector 700.

[0110] like Figures 7-9 As shown, the bent portion 510 is provided with a first mounting hole 511, the horizontal portion 520 has a groove 521, and the second connector 700 passes through the first mounting hole 511 and is slidably assembled in the groove 521 along the second direction z2. The second direction z2 intersects with the first direction z1.

[0111] In this embodiment, the second connector 700 may include a bolt and a nut. The opening of the groove 521 is provided with a protrusion extending toward the opposite groove wall. The nut is pre-set in the groove 521, and both ends of the nut abut against the groove wall of the groove 521. The bent part 510 is fitted onto the horizontal part 520, and the first mounting hole 511 is aligned with the nut in the groove 521. After the bolt passes through the first mounting hole 511, it is connected to the nut. The nut rises along the thread and abuts against the lower surface of the protrusion in the groove 521. When the bent part 510 is pulled or pushed to move along the second direction z2, the nut slides along the protrusion in the groove 521 to adjust the width of the snap-fit ​​groove 600, thereby adapting to cement walls of different thicknesses and having good versatility.

[0112] It should be noted that in this embodiment, the first direction z1 is the height direction of the mounting bracket 100, and the second direction z2 is perpendicular to the first direction z1.

[0113] According to the mounting bracket 10 provided in the embodiments of this application, a second connector 700 is provided that slides through the first mounting hole 511 and is fitted into the groove 521 along the second direction z2. This allows for adjustment of the distance between the bent portion 510 and the mounting bracket 100 when the mounting bracket 100 is installed, thereby changing the width of the snap-fit ​​groove 600. This adapts to different installation scenarios, has good versatility, and is low in cost.

[0114] In some embodiments, such as Figure 7 As shown, the first mounting hole 511 and the second connector 700 may each have multiple holes.

[0115] like Figure 7 and Figure 8 As shown, at least one first mounting hole 511 is an elongated hole, and a second connector 700 corresponding to the first mounting hole 511 is slidably assembled in the first mounting hole 511.

[0116] In this embodiment, there are two first mounting holes 511, one is a round hole and the other is an elongated hole. Two second connectors 700 correspond to the two first mounting holes 511 respectively. The second connectors 700 may include bolts and nuts. The opening of the groove 521 is provided with a protrusion extending toward the opposite groove wall. The nut is pre-set in the groove 521, and both ends of the nut abut against the groove wall of the groove 521. The bent part 510 is fitted onto the horizontal part 520, and the first mounting hole 511 is aligned with the nut in the groove 521. After the bolt passes through the first mounting hole 511, it is connected to the nut. The nut rises along the thread and abuts against the lower surface of the protrusion in the groove 521. When the bent part 510 is pulled or pushed to move along the second direction z2, the nut slides along the protrusion in the groove 521 to adjust the width of the snap-fit ​​groove 600, thereby adapting to cement walls of different thicknesses and having good versatility.

[0117] When aligning the first mounting hole 511 with the nut in the groove 521, the round hole can be aligned with the nut first. The elongated hole has a larger range, and when the round hole is aligned with the nut, the other nut will correspond to the elongated hole. Alternatively, the elongated hole can be aligned with the nut first, and then the round hole can be aligned with the nut by making minor adjustments within the length range of the elongated hole. This adjustment is simple and easy to install.

[0118] In some embodiments, the mounting bracket 10 may also include a third connector 800.

[0119] like Figures 6-8 As shown, the side wall of the bent portion 510 away from the mounting bracket 100 is provided with a second mounting hole 512, and the third connector 800 passes through the second mounting hole 512 and is connected to the horizontal portion 520.

[0120] In this embodiment, the bending portion 510 includes a first part 514 and a second part 515 in a 90° vertical state. The first part 514 is connected to the horizontal part 520. The end of the horizontal part 520 away from the bending portion 510 is connected to the mounting bracket 100. The second part 515 forms a snap-fit ​​groove 600 with the mounting bracket 100. The first part 514 is provided with a second mounting hole 512. The third connector 800 can be a bolt. A connecting plate can be provided below the outer wall of the groove 521 of the horizontal part 520. The third connector 800 passes through the second mounting hole 512 and is connected to the connecting plate. The axis of the third connector 800 intersects with that of the second connector 700. It can withstand the forces applied to the mounting bracket 100 and the photovoltaic module 20 in different directions. The mounting bracket 10 has good stability, ensuring that the photovoltaic system 1 can work normally.

[0121] According to the mounting bracket 10 provided in the embodiments of this application, by providing first mounting holes 511 of different shapes in the bending portion 510, it is convenient to install the second connector 700, the adjustment is simple, and the installation efficiency is high. By providing second mounting holes 512 on the side wall of the bending portion 510 that are not adjacent to the first mounting holes 511, it is convenient to install connectors in different directions, improve the load-bearing capacity of the clamp 500, and the mounting bracket 10 has good stability, ensuring that the photovoltaic system 1 can work normally.

[0122] In some embodiments, the clamp 500 may also include a protective sleeve 530.

[0123] like Figure 4 and Figure 5 As shown, the protective sleeve 530 is fitted onto the bend of the bending portion 510.

[0124] In this embodiment, the bending portion 510 includes a first portion 514 and a second portion 515 in a 90° vertical state. The first portion 514 is connected to the horizontal portion 520. The end of the horizontal portion 520 away from the bending portion 510 is connected to the mounting bracket 100. The second portion 515 forms a snap-fit ​​groove 600 with the mounting bracket 100. The protective sleeve 530 is fitted onto the connection between the first portion 514 and the second portion 515 of the bending portion 510. Due to material and processing reasons, there may be hard sharp corners at the connection between the first portion 514 and the second portion 515. The protective sleeve 530 can prevent the sharp corners from causing injury to people in the room.

[0125] The protective cover 530 can be made of rubber, PVC (polyvinyl chloride), or other soft materials.

[0126] In this embodiment, the protective sleeve 530 can be made of rubber, which has good wear resistance and high temperature resistance.

[0127] In some embodiments, such as Figure 5 As shown, the fixture 500 may also include a baffle 540.

[0128] The baffle 540 is slidably mounted on the side of the bent part 510 near the installation scene along the second direction z2, and the second direction z2 intersects with the first direction z1.

[0129] In this embodiment, the bending portion 510 includes a first portion 514 and a second portion 515 in a 90° vertical state. The first portion 514 is connected to the horizontal portion 520. The end of the horizontal portion 520 away from the bending portion 510 is connected to the mounting bracket 100. The second portion 515 and the mounting bracket 100 form a snap-fit ​​groove 600. The bottom of the second portion 515 is provided with a sliding hole extending along the second direction z2. The baffle 540 is slidably fitted into the sliding hole. The side wall of the second portion 515 on the side opposite to the baffle 540 is provided with a pushing portion 550 (such as a push rod) that penetrates the side wall. When the snap-fit ​​groove 600 is snapped into the cement wall, the pushing portion 550 can push the baffle 540 to move along the second direction z2, so that the baffle 540 abuts against the cement wall surface, increasing the friction and improving the snap-fit ​​effect.

[0130] In some embodiments, such as Figure 5 and Figure 6 As shown, the bent portion 510 may be provided with a limiting member 513.

[0131] The end of the horizontal part 520 that is away from the mounting bracket 100 abuts against the limiting member 513.

[0132] In this embodiment, the bending portion 510 includes a first part 514 and a second part 515 in a 90° vertical state. The first part 514 is connected to the horizontal part 520. The end of the horizontal part 520 away from the bending portion 510 is connected to the mounting bracket 100. The second part 515 and the mounting bracket 100 form a snap-fit ​​groove 600. A limiting member 513 is provided near the connection point between the second part 515 and the first part 514. When the bending portion 510 is fitted onto the horizontal part 520, the end of the horizontal part 520 away from the mounting bracket 100 abuts against the limiting member 513 to complete the installation. The installation is simple and has a high accuracy.

[0133] According to the mounting bracket 10 provided in the embodiments of this application, by providing a protective sleeve 530 on the bending portion 510, the sharp corner can prevent injury to indoor personnel, thus ensuring high safety. By providing a baffle 540 that can slide along the second direction z2 on the bending portion 510, the friction between the clamp 500 and the installation scene is increased, resulting in a better locking effect. By providing a limiting member 513 on the bending portion 510, the bending portion 510 is easy to operate when fitted onto the horizontal portion 520, and the installation accuracy is high.

[0134] In some embodiments, such as Figure 10 As shown, the sliding part 110 may include a sliding groove 111 and a locking groove 112.

[0135] The slide groove 111 extends along the first direction z1, and the locking groove 112 is connected to the slide groove 111.

[0136] In this embodiment, the first direction z1 is the height direction of the mounting bracket 100.

[0137] The sliding groove 111 and the locking groove 112 are distributed along the second direction z2, which intersects with the first direction z1.

[0138] In this embodiment, the second direction z2 is perpendicular to the first direction z1, and the sliding groove 111 and the locking groove 112 are distributed on the mounting bracket 100 along the second direction z2.

[0139] The adjusting beam 200 is movably assembled in the slide groove 111 along the first direction z1 via the first connector 300, and the adjusting beam 200 is connected to the locking groove 112 via the first connector 300.

[0140] In this embodiment, the first connector 300 is slidably mounted on the slide groove 111 of the mounting bracket 100, and the first connector 300 passes through the slide groove 111 and is connected to the adjusting beam 200. The locking groove 112 is connected to the slide groove 111. When the adjusting beam 200 is moved along the first direction z1, the first connector 300 slides in the slide groove 111 along the first direction z1. After the photovoltaic module 20 is adjusted to a suitable angle, the connector is slid to the locking groove 112 and locked.

[0141] According to the mounting bracket 10 provided in the embodiments of this application, by setting the structure of the sliding part 110, the sliding and locking of the adjusting beam 200 can be realized, the angle adjustment process of the mounting bracket 10 is simplified, and the power generation efficiency of the photovoltaic system 1 is improved.

[0142] In some embodiments, such as Figure 10 As shown, the sliding part 110 may also include a connecting groove 113.

[0143] The slide groove 111 is connected to the locking groove 112 through the connecting groove 113.

[0144] In this embodiment, the connecting groove 113 is located between the sliding groove 111 and the locking groove 112. The sliding groove 111 is connected to the locking groove 112 through the connecting groove 113. When the adjusting beam 200 is pushed so that the first connecting member 300 moves in the sliding groove 111, the first connecting member 300 can slide into the locking groove 112 along the connecting groove 113. The guiding effect is good, and the process of the first connecting member 300 sliding into the locking groove 112 is relatively smooth.

[0145] In some embodiments, the connecting groove 113 may be an arc-shaped groove, and the locking groove 112 may extend upward along the first direction z1.

[0146] For example, both the locking groove 112 and the sliding groove 111 extend along the first direction z1, wherein the locking groove 112 extends upward along the first direction z1, and the connecting groove 113 is an upwardly extending arc-shaped groove. When the first connector 300 slides upward in the sliding groove 111, it slides into the upwardly extending locking groove 112 along the arc-shaped connecting groove 113, and the operation is smooth. The first connector 300 does not need to change its sliding direction. The upwardly extending arc-shaped connecting groove 113 makes the connection between the locking groove 112, the sliding groove 111, and the connecting groove 113 not on the same horizontal plane, thus preventing the first connector 300 from sliding out when the mounting bracket 10 is subjected to external forces such as vibration, and the locking effect is good.

[0147] It is understandable that the mounting bracket 100 may be provided with multiple locking grooves 112 at intervals along the first direction z1.

[0148] According to the mounting bracket 10 provided in the embodiments of this application, by providing a connecting groove 113 for connecting the sliding groove 111 and the locking groove 112, the first connecting member 300 can slide into the locking groove 112, which has good guiding properties and makes the angle adjustment operation of the photovoltaic module 20 simpler and more accurate.

[0149] In some embodiments, such as Figure 11 As shown, the mounting bracket 100 may have a receiving slot 130.

[0150] like Figure 3 and Figure 11 As shown, in this embodiment, the mounting bracket 100 may include a column body 140 disposed opposite to it, and the column body 140 has a receiving groove 130.

[0151] The receiving slot 130 opens towards the diagonal brace 400.

[0152] The receiving groove 130 can be located in the middle section of the column body 140, or it can extend from one end of the column body 140 to the other end.

[0153] In this embodiment, the receiving slot 130 can be configured to extend from one end of the column body 140 to the other end, thereby reducing the weight of the column body 140 and facilitating storage and transportation.

[0154] The end of the diagonal brace 400 extends into the receiving groove 130 and is hinged to the mounting bracket 100. The mounting bracket 10 has a retracted state in which at least a portion of the diagonal brace 400 is retracted into the receiving groove 130.

[0155] In this embodiment, the column body 140 of the mounting bracket 100 has a receiving groove 130 that opens toward the diagonal brace 400. The receiving groove 130 extends from one end of the column body 140 to the other end. One end of the diagonal brace 400 extends into the receiving groove 130 and is hinged to the first connecting member 300 that passes through the column body 140. When the adjusting beam 200 is pushed, the end of the diagonal brace 400 that extends into the receiving groove 130 rotates around the first connecting member 300. After rotating to a certain angle, the diagonal brace 400 can be stored in the receiving groove 130 or unfolded from the receiving groove 130.

[0156] According to the mounting bracket 10 provided in the embodiments of this application, by providing a receiving groove 130 in the mounting bracket 100, the diagonal brace 400 can be stored in or unfolded from the receiving groove 130, thereby realizing the folding or unfolding of the photovoltaic module 20, which is convenient for storage and transportation.

[0157] In some embodiments, such as Figure 3 and Figure 4 As shown, the adjusting beam 200 may have a threaded hole 222.

[0158] The first connector 300 is threadedly connected to the threaded hole 222.

[0159] In this embodiment, the first connector 300 can be a T-bolt. The mounting bracket 100 includes two column bodies 140 arranged opposite each other. The adjusting beam 200 is clamped between the two column bodies 140. The two ends of the adjusting beam 200 are provided with threaded connectors with threaded holes 222. The first connector 300 passes through the column body 140 and is threadedly connected to the threaded connector. The operation is simple. The tilt angle of the photovoltaic module 20 can be adjusted within a certain range by directly pushing it. Pushing the adjusting beam 200 causes the T-bolts at both ends to slide in the grooves 111 of the column body 140, which can adjust the tilt angle within a large range. When the preset angle is reached, the T-bolt is then locked. The tilt angle adjustment of the photovoltaic module 20 is simple.

[0160] In some embodiments, such as Figures 14-16 As shown, a threaded section 211 can also be directly opened on the adjusting beam 200. The threaded section 211 has a threaded hole 222, and the adjusting beam 200 is bolted to the first connecting piece 300.

[0161] According to the mounting bracket 10 provided in the embodiments of this application, a threaded hole 222 is provided in the adjusting beam 200 to facilitate the connection between the first connector 300 and the adjusting beam 200.

[0162] In some embodiments, such as Figure 3 and Figure 4 As shown, the adjusting beam 200 may include a beam body 210 and a knob 220.

[0163] like Figure 12 As shown, the knob 220 has a slot 221 and a threaded hole 222, the crossbeam body 210 is inserted into the slot 221, and the first connector 300 is threadedly connected to the threaded hole 222.

[0164] In this embodiment, the first connector 300 can be a T-bolt. The mounting bracket 100 includes two opposing column bodies 140. The adjusting beam 200 is clamped between the two column bodies 140. The two ends of the beam body 210 are inserted into the slots 221 of the knob 220. The first connector 300 passes through the column body 140 and is threadedly connected to the threaded hole 222 of the knob 220. Rotating the knob 220 can fix and unlock the adjusting beam 200, which is easy to operate. Directly pushing the photovoltaic module 20 can adjust the tilt angle within a certain range. Pushing the beam body 210 causes the T-bolts at both ends to slide in the grooves 111 of the column body 140, which can adjust the tilt angle within a larger range to reach the preset angle position. Then, by rotating the knob 220, the knob 220 is locked with the T-bolt. The tilt angle adjustment of the photovoltaic module 20 is simple.

[0165] In some embodiments, such as Figure 16 As shown, the adjusting beam 200 may include a beam body 210, and a threaded section 211 with a threaded hole 222 may be directly opened on the beam body 210. The beam body 210 is bolted to the first connecting member 300.

[0166] According to the mounting bracket 10 provided in the embodiments of this application, by setting the structure of the adjusting beam 200 and adjusting the assembly relationship between the adjusting beam 200 and the first connecting member 300, the tilt angle of the photovoltaic module 20 can be adjusted, and the operation is simple.

[0167] In some embodiments, such as Figure 3 As shown, the mounting bracket 100 may have a first hinge structure 120 for hinged to the photovoltaic module 20 of the photovoltaic system 1.

[0168] In this embodiment, the first hinge structure 120 is disposed on the upper part of the mounting frame 100 along the first direction z1. The end of the first hinge structure 120 away from the mounting frame 100 is provided with a pin. The first hinge structure 120 is hinged to the photovoltaic module 20 of the photovoltaic system 1 through the pin.

[0169] The diagonal brace 400 is hinged to the mounting frame 100 via the first connector 300. The diagonal brace 400 has a second hinge structure 410, which is hinged to the photovoltaic module 20.

[0170] For example, the second hinge structure 410 can be a pin.

[0171] like Figure 2 and Figure 3As shown, the first hinge structure 120 and the second hinge structure 410 are arranged at intervals.

[0172] In this embodiment, the first hinge structure 120 and the second hinge structure 410 are spaced apart along the first direction z1. One end of the diagonal brace 400 is hinged to the first connector 300, and the other end of the diagonal brace 400 is hinged to the photovoltaic module 20 through the second hinge structure 410.

[0173] In this embodiment, the mounting bracket 10 has a sliding groove 111 extending along a first direction z1 and a locking groove 112 communicating with the sliding groove 111. The sliding groove 111 and the locking groove 112 are distributed along a second direction z2. The upper part of the mounting bracket 100 along the first direction z1 has a first hinge structure 120 for hinged connection with the photovoltaic module 20. A first connector 300 is slidably assembled with the sliding groove 111. One end of the first connector 300 passes through the mounting bracket 100 and is connected to the adjusting beam 200. One end of the diagonal brace 400 is hinged to the first connector 300, and the other end of the diagonal brace 400 is hinged to the photovoltaic module 20 through a second hinge structure 410. The mounting bracket 100 adapts to changes in light conditions. When the tilt angle of the photovoltaic module 20 needs to be adjusted, the adjusting beam 200 is pushed to move the first connecting piece 300 within the slide groove 111. The diagonal brace 400, which is hinged to the first connecting piece 300, rotates around the first connecting piece 300. This causes the photovoltaic module 20, which is hinged to the other end of the diagonal brace 400, to rotate simultaneously around the rotation axes of the second hinge structure 410 and the first hinge structure 120. After the first connecting piece 300 is moved into the locking groove 112 and locked, the angle adjustment of the photovoltaic module 20 is completed. The angle adjustment of the photovoltaic module 20 can be completed simply by pushing the adjusting beam 200. When the seasons change, the user can adjust the angle himself. The operation is simple and convenient.

[0174] According to the mounting bracket 10 provided in the embodiments of this application, by setting a first hinge structure 120 and a second hinge structure 410 that are hinged to the photovoltaic module 20, the bracket ensures the support of the photovoltaic module 20 while facilitating the adjustment of the tilt angle of the photovoltaic module 20. The operation is simple and the adjustment efficiency is high. The embodiments of this application also provide a photovoltaic system 1.

[0175] like Figure 1 , Figure 2 and Figure 13 As shown, the photovoltaic system 1 includes: a mounting bracket 10 and a photovoltaic module 20.

[0176] Mounting bracket 10 is the mounting bracket 10 described in the above embodiment.

[0177] The photovoltaic module 20 is hinged to the mounting bracket 10.

[0178] The photovoltaic module 20 includes, but is not limited to, a laminate 21 and a frame 22. The laminate 21 is mounted on the frame 22 and includes a front panel, an encapsulant film, a cell, an encapsulant film, and a back panel stacked in sequence.

[0179] In this embodiment, the frame 22 of the photovoltaic module 20 is hinged to the diagonal brace 400 and the mounting frame 100. The mounting frame 100 has a sliding part 110 extending along the first direction z1 and a first hinge structure 120 for hinged with the photovoltaic module 20. The first connector 300 is slidably assembled with the sliding part 110. One end of the first connector 300 passes through the mounting frame 100 and is connected to the adjusting beam 200. One end of the diagonal brace 400 is hinged to the first connector 300, and the other end of the diagonal brace 400 is hinged to the photovoltaic module 20 through the second hinge structure 410. A clamp 500 is also installed on the side of the mounting frame 100 opposite to the photovoltaic module 20. A snap-fit ​​groove 600 is formed between the clamp 500 and the mounting frame 100. The snap-fit ​​groove 600 snaps into the installation scene (such as a balcony cement wall), and the snap-fit ​​is firm and secure. The mounting bracket 100 is not easily shaken and has good stability. It does not require drilling or damaging the structure at the installation site, and can be installed quickly. When the light conditions change and the tilt angle of the photovoltaic module 20 needs to be adjusted, the adjustment beam 200 is pushed to move the first connector 300 within the sliding part 110. The diagonal brace 400, which is hinged to the first connector 300, rotates around the first connector 300. This causes the photovoltaic module 20, which is hinged to the other end of the diagonal brace 400, to rotate simultaneously around the rotation axes of the second hinge structure 410 and the first hinge structure 120. After locking the first connector 300, the angle adjustment of the photovoltaic module 20 is completed. The angle adjustment of the photovoltaic module 20 can be completed simply by pushing the adjustment beam 200. When the seasons change, the user can adjust the angle himself. The operation is simple and convenient.

[0180] According to the photovoltaic system 1 provided in the embodiments of this application, by hinged photovoltaic module 20 to mounting bracket 10, it is convenient to install photovoltaic module 20 in the installation scene, and at the same time, it is convenient to help photovoltaic system 1 to more accurately adjust the solar tracking angle and improve the power generation efficiency of photovoltaic system 1.
