[0059] 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.

[0060] The principle of the photovoltaic bracket 1000 proposed in this application will be explained in detail below:

[0061] In related technologies, the drive mechanism of a photovoltaic system suffers from significant energy loss and low drive efficiency during operation, resulting in poor tracking performance of the photovoltaic bracket.

[0062] To address this technical problem, this application provides a photovoltaic bracket 1000, as described below. Figures 1-8 A photovoltaic bracket 1000 according to an embodiment of this application is described.

[0063] like Figures 1-3 As shown, the photovoltaic bracket 1000 of this application embodiment includes: a drive column 100, a support column 200, a main shaft 300, a drive mechanism 400, and a self-locking mechanism 500.

[0064] The drive column 100 and the support column 200 are arranged at intervals along the first direction.

[0065] It should be noted that in this embodiment, the first direction is the axial direction of the main shaft 300.

[0066] In some embodiments, the first direction may also be set to other directions.

[0067] The spindle 300 extends along the first direction.

[0068] The main shaft 300 is supported by the drive column 100 and the support column 200, and is used to support the photovoltaic module.

[0069] The spindle 300 can be made of materials such as stainless steel, cast iron, aluminum alloy, galvanized steel, and composite materials.

[0070] In this embodiment, the spindle 300 is made of aluminum alloy, which is lightweight, high-strength, and corrosion-resistant.

[0071] The cross-sectional shape of the spindle 300 can be circular, rectangular, polygonal or other special shapes, and no specific restrictions are imposed in this embodiment.

[0072] like Figure 2 and Figure 3As shown, the drive mechanism 400 is mounted on the drive column 100.

[0073] The output end of the drive mechanism 400 is connected to the spindle 300.

[0074] In this embodiment, the drive mechanism 400 is installed at the upper end of the drive column 100, which facilitates the connection of the output end of the drive mechanism 400 to the spindle 300 and prevents interference.

[0075] like Figure 2 and Figure 3 As shown, the self-locking mechanism 500 is installed on the drive column 100.

[0076] In this embodiment, the self-locking mechanism 500 is installed on the side wall of the drive column 100, and the self-locking mechanism 500 does not interfere with the drive mechanism 400 when it is working.

[0077] The self-locking mechanism 500 is configured to lock with the spindle 300 when the spindle 300 is in its initial position.

[0078] It should be noted that in this embodiment, the initial position of the main shaft 300 is when the photovoltaic module is in a horizontal state.

[0079] In some embodiments, the initial position can be set according to the specific use case.

[0080] In related technologies, the drive mechanism of a photovoltaic system requires multiple components to drive the main shaft to rotate, resulting in significant energy loss, low drive efficiency, and poor tracking performance of the photovoltaic bracket.

[0081] In this embodiment, the photovoltaic bracket 1000 has a drive column 100 and a support column 200 arranged sequentially along a first direction. The drive mechanism 400 is mounted on the drive column 100, and the output end of the drive mechanism 400 is directly connected to the main shaft 300, resulting in high transmission efficiency. The drive column 100 is also equipped with a self-locking mechanism 500, which locks the main shaft 300 when it is in the initial position, resulting in good stability.

[0082] According to the photovoltaic bracket 1000 provided in the embodiments of this application, the drive column 100 and the support column 200 are arranged at intervals along the first direction, and the drive mechanism 400 and the self-locking mechanism 500 are installed on the drive column 100 to realize direct drive and self-locking of the main shaft 300. While ensuring the driving capability, the transmission efficiency is high and the self-locking effect is good.

[0083] In some embodiments, such as Figure 2 and Figure 3 As shown, a locking element 600 may be provided on the spindle 300.

[0084] The locking pin 510 of the self-locking mechanism 500 is adapted to move in a first direction to lock or unlock with the locking member 600.

[0085] In this embodiment, the first direction is the axial direction of the main shaft 300.

[0086] When the locking pin 510 of the self-locking mechanism 500 moves away from the drive column 100 along the first direction, the locking pin 510 connects with the locking member 600 and locks the spindle 300; when the locking pin 510 of the self-locking mechanism 500 moves closer to the drive column 100 along the first direction, the locking pin 510 disconnects from the locking member 600 and unlocks the spindle 300.

[0087] According to the photovoltaic bracket 1000 provided in the embodiments of this application, by providing a locking member 600 on the main shaft 300, the locking pin 510 can better lock or unlock the main shaft 300 by cooperating with the locking member 600.

[0088] In some embodiments, such as Figure 3 and Figure 4 As shown, the self-locking mechanism 500 may include a drive element 520 and a locking pin 510.

[0089] like Figure 3 As shown, the drive component 520 is mounted on the drive column 100.

[0090] In this embodiment, the driving component 520 is installed on the side wall of the driving column 100, and the self-locking mechanism 500 does not interfere with the driving mechanism 400 when it is working.

[0091] In some embodiments, the drive unit 520 may also be installed at other locations on the drive column 100.

[0092] The drive component 520 can be installed on the drive column 100 through various connection methods. In this embodiment, the drive component 520 is installed on the drive column 100 by bolt connection, which has high connection strength and is easy to disassemble and assemble.

[0093] like Figure 4 As shown, the drive unit 520 has an output end adapted to move along a first direction.

[0094] Locking pin 510 is connected to the output end of drive component 520.

[0095] The output end of the drive unit 520 drives the locking pin 510 to move in the first direction away from or towards the drive column 100.

[0096] According to the photovoltaic bracket 1000 provided in the embodiments of this application, the locking pin 510 can be moved by the driving component 520, which can more conveniently lock or unlock the main shaft 300.

[0097] In some embodiments, such as Figure 3 and Figure 4 As shown, the self-locking mechanism 500 may further include: an adapter plate 530.

[0098] The adapter board 530 is installed at the output end of the driver 520.

[0099] The adapter plate 530 is located inside the self-locking mechanism 500.

[0100] The adapter plate 530 can be made of materials such as aluminum alloy, stainless steel, galvanized steel, and composite materials.

[0101] In this embodiment, the adapter plate 530 is made of aluminum alloy, which is lightweight, high-strength, and corrosion-resistant.

[0102] There are multiple locking pins 510.

[0103] Multiple locking pins 510 are installed on the adapter plate 530.

[0104] In this embodiment, there are three locking pins 510, which are evenly spaced on the adapter plate 530, resulting in a stable structure.

[0105] like Figure 3 and Figure 6 As shown, the locking member 600 is provided with multiple locking holes 610, and each locking hole 610 corresponds to a locking pin 510.

[0106] According to the photovoltaic bracket 1000 provided in the embodiments of this application, by setting an adapter plate 530 in the self-locking mechanism 500, the driving component 520 drives the adapter plate 530 to drive multiple locking pins 510 to move simultaneously, resulting in a good self-locking effect.

[0107] In some embodiments, such as Figures 3-5 As shown, the self-locking mechanism 500 may also include a guide member 540.

[0108] Guide component 540 is installed on drive column 100.

[0109] The guide component 540 can be installed on the drive column 100 by means of threaded connection, hinge, crimping and adhesive bonding, etc., and no specific limitation is made in this embodiment.

[0110] The guide component 540 can be of various structures, such as guide rails, guide plates, and cylinders, depending on the specific application.

[0111] The guide member 540 is provided with a guide hole 541, and the locking pin 510 passes through the guide hole 541.

[0112] The locking pin 510 can move along the guide hole 541 in the first direction away from or towards the drive column 100.

[0113] According to the photovoltaic bracket 1000 provided in the embodiments of this application, by setting the guide 540, it is convenient to support and position the locking pin 510, and the locking and unlocking of the main shaft 300 is more stable.

[0114] In some embodiments, such as Figure 4 and Figure 5 As shown, the guide member 540 may include multiple guide plates 542.

[0115] Multiple guide plates 542 are spaced apart along the first direction.

[0116] Each of the multiple guide plates 542 is provided with a corresponding guide hole 541.

[0117] In this embodiment, the guide component 540 consists of two guide plates 542, which has a simple structure.

[0118] Of the two guide plates 542, the one closer to the locking member 600 serves a guiding function, while the one farther away from the locking member 600 serves both a guiding function and a supporting function for the locking pin 510.

[0119] It should be noted that the number of guide plates 542 can be set according to the length of the locking pin 510 and the actual use. The guide plates 542 can be evenly spaced or the distance can be set freely.

[0120] In some embodiments, the drive member 520 may also be provided with a guide plate 542, on which a guide hole 541 is provided for the output end of the drive member 520, so that the output end of the drive member 520 can stably drive the locking pin 510.

[0121] According to the photovoltaic bracket 1000 provided in the embodiments of this application, multiple guide plates 542 are spaced apart along a first direction. Each guide plate 542 is provided with a corresponding guide hole 541. The guide plate 542 guides the locking pin 510 while also supporting the locking pin 510. It can be used for locking pins 510 of different lengths and has strong versatility.

[0122] In some embodiments, such as Figure 2 and Figure 3 As shown, a clamping element 700 may be provided on the spindle 300.

[0123] Locking element 600 is installed on clamping element 700.

[0124] In this embodiment, the clamping member 700 consists of an upper clamp and a lower clamp, and the locking member 600 is integrated with the lower clamp, resulting in a high degree of integration. When the locking pin 510 is connected to the locking member 600, the locking effect on the spindle 300 is better.

[0125] like Figure 6As shown, the locking member 600 has a plate-like structure, and a locking hole 610 is provided at the lower end of the locking member 600.

[0126] In this embodiment, there are three locking holes 610 and three locking pins 510, which correspond one-to-one with the locking holes 610, resulting in a good locking effect.

[0127] According to the photovoltaic bracket 1000 provided in the embodiments of this application, by setting a clamping member 700 on the main shaft 300 and connecting the locking member 600 to the clamp, the main shaft 300 can be stabilized and locked at the same time, with high integration and good locking effect.

[0128] In some embodiments, such as Figure 2 and Figure 3 As shown, the drive mechanism 400 may include: a motor 410, a first planetary reducer 420, and a second planetary reducer 430.

[0129] Motor 410 is mounted on drive column 100.

[0130] In this embodiment, the motor 410 is mounted on the upper surface of the drive column 100 to facilitate driving the spindle 300.

[0131] The motor 410, the first planetary reducer 420, and the second planetary reducer 430 are connected in sequence.

[0132] The output end of the motor 410 is connected to the input end of the first planetary reducer 420.

[0133] The output end of the first planetary reducer 420 is connected to the input end of the second planetary reducer 430, and the output end of the second planetary reducer 430 is connected to the spindle 300.

[0134] In this embodiment, a motor 410 is used in conjunction with a two-stage planetary reducer to drive the main shaft 300, which can achieve more efficient torque transmission. Under the same power, the maximum length of a single row of the photovoltaic bracket 1000 is longer, and the power loss of the photovoltaic bracket 1000 is smaller when the single row length is the same.

[0135] According to the photovoltaic bracket 1000 provided in the embodiments of this application, the main shaft 300 is driven by the motor 410 in conjunction with the first planetary reducer 420 and the second planetary reducer 430, so the photovoltaic bracket 1000 has a stronger load-bearing capacity and higher transmission efficiency.

[0136] In some embodiments, such as Figure 2 and Figure 3 As shown, a motor 410 seat 110 can be installed on the drive column 100.

[0137] The motor 410 is mounted on the motor 410 base 110, which provides stable support, is securely installed, and is easy to install and remove.

[0138] In some embodiments, the motor 410 may also be directly connected to the drive column 100.

[0139] The connection between the motor 410 and the motor 410 base 110 can be achieved by bolt connection, plug-in connection, clamp connection, or welding.

[0140] In this embodiment, the connection between the motor 410 and the motor 410 base 110 is a bolt connection, which has high connection strength and is easy to disassemble and assemble.

[0141] According to the photovoltaic bracket 1000 provided in the embodiments of this application, by setting a motor 410 seat 110 on the drive column 100 and installing the motor 410 on the motor 410 seat 110, a stable support can be provided for the motor 410, the installation is firm and easy to disassemble and assemble, and the driving effect of the motor 410 is better.

[0142] In some embodiments, such as Figure 1 As shown, drive columns 100 can be provided at both ends of the spindle 300.

[0143] The two ends of the main shaft 300 are respectively connected to the output ends of the corresponding second planetary reducer 430.

The output end of the second planetary reducer 430 is connected to the main shaft 300, and the support column 200 is spaced between the drive columns 100 at both ends.

[0145] According to the photovoltaic bracket 1000 provided in the embodiments of this application, by setting the drive column 100 at both ends of the main shaft 300 and the support column 200 spaced between the drive columns 100 at both ends, it has a better driving effect and better support.

[0146] In some embodiments, such as Figure 7 and Figure 8 As shown, the drive column 100 can be provided with support columns 200 on both sides along the first direction, and the second planetary reducer 430 is provided with output ends on both sides of the first direction. The output ends on both sides of the second planetary reducer 430 are each connected to a corresponding spindle 300.

[0148] According to the photovoltaic bracket 1000 provided in the embodiment of this application, the second planetary reducer 430 has output ends on both sides in the first direction. Each output end on both sides of the second planetary reducer 430 is connected to a corresponding main shaft 300, which can drive a photovoltaic bracket 1000 with a longer single row.

[0149] In some embodiments, drive columns 100 are located at both ends of spindle 300, motor 410, first planetary reducer 420 and second planetary reducer 430 are connected in sequence, the output end of second planetary reducer 430 is connected to spindle 300, motor 410 is mounted on drive column 100 through motor 410 seat 110, and support columns 200 are spaced apart between drive columns 100 at both ends along a first direction to support spindle 300.

The self-locking mechanism 500 is provided with a guide member 540. The drive member 520 of the self-locking mechanism 500 pushes the adapter plate 530, thereby causing the locking pins 510 to move along the axial direction of the spindle 300 in the guide hole 541 of the guide member 540. The locking pins 510 cooperate with the locking hole 610 on the locking member 600. The locking member 600 is integrated with the clamping member 700 on the spindle 300, realizing the locking and unlocking of the spindle 300 in the initial position.
