[0044] 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.

[0045] The following is for reference. Figures 1-10This application describes a speed reducer 1 for a photovoltaic bracket 100, a photovoltaic bracket 100, and a photovoltaic system according to embodiments thereof.

[0046] like Figure 4 and Figure 9 As shown, the reducer 1 for a photovoltaic bracket 100 according to an embodiment of this application includes: a support 10, a drive member 20, a transmission shaft connector 40, and a main shaft connector 30. The drive member 20 is disposed on the support 10 and has a drive shaft 201. The transmission shaft connector 40 and the main shaft connector 30 are rotatably disposed on the support 10 and are both connected to the drive shaft 201. The main shaft connector 30 is adapted to be connected to the main shaft 3, and the transmission shaft connector 40 is adapted to be connected to the transmission shaft 4. When the transmission shaft connector 40 and the main shaft connector 30 are configured to be mounted on the transmission shaft 4 and the main shaft 3, the axis of the transmission shaft 4 and the axis of the main shaft 3 are parallel to the axis of the drive shaft 201.

[0047] The driving component 20 is disposed on the support 10. For example, the driving component 20 can be disposed on the support 10 by means of bolt connection, snap-fit, etc. The driving component 20 has a driving shaft 201, which can serve as an input shaft to transmit power to the inside of the reducer 1. As some embodiments of this application, a bearing is provided between the driving shaft 201 and the support 10. The bearing is sleeved on the outside of the driving shaft 201. The bearing and the driving shaft 201 can be connected by means of, but not limited to, transition fit or clearance fit, so that the driving shaft 201 can rotate relative to the support 10. As some embodiments of this application, the driving component 20 can be constructed as a motor, and the driving shaft 201 can be a motor shaft.

[0048] The drive shaft connector 40 can pass through the support 10 and be rotatably connected to the support 10. That is, the support 10 is used to accommodate a portion of the drive shaft connector 40, and the drive shaft connector 40 can rotate relative to the support 10. As some embodiments of this application, a bearing is provided between the drive shaft connector 40 and the support 10. The bearing is sleeved on the outside of the drive shaft connector 40. The bearing and the drive shaft connector 40 can be connected by, but not limited to, an transition fit or a clearance fit, so that the drive shaft connector 40 can rotate relative to the support 10.

[0049] The spindle connector 30 can pass through the support 10 and be rotatably connected to the support 10. That is, the support 10 is used to accommodate the portion of the spindle connector 30, and the spindle connector 30 can rotate relative to the support 10. As some embodiments of this application, a bearing is provided between the spindle connector 30 and the support 10. The bearing is sleeved on the outside of the spindle connector 30. The bearing and the spindle connector 30 can be connected by, but not limited to, an transition fit or a clearance fit, so that the spindle connector 30 can rotate relative to the support 10.

[0050] As some embodiments of this application, along the axial direction of the spindle connector 30, both ends of the spindle connector 30 can be connected to two spindles 3 respectively, so that the spindle connector 30 can transmit power to the spindles 3 at both ends simultaneously, so that the reducer 1 can synchronously drive the spindles 3 at both ends. It is understood that the spindles 3 can drive the photovoltaic module 200 to rotate. As some embodiments of this application, the spindle connector 30 and the spindle 3 can be connected by means of, but not limited to, bolt connection, snap-fit ​​connection, etc.

[0051] As some embodiments of this application, along the axial direction of the drive shaft connector 40, both ends of the drive shaft connector 40 can be connected to two drive shafts 4 respectively, so that the drive shaft connector 40 can transmit power to the drive shafts 4 at both ends simultaneously. The drive shafts 4 at both ends can be connected to two driven reducers 2 respectively, so that the reducers 1 can synchronously drive the drive shafts 4 at both ends to drive the driven reducers 2 at both ends. It should be noted that the driven reducers 2 can also drive the main shaft 3 to rotate, so that the main shaft 3 has multiple positions for support, thereby reducing the risk of slight deformation in the middle part of the main shaft 3 and improving the stability of power transmission. As some embodiments of this application, the drive shaft connector 40 and the drive shaft 4 can be connected by means of, but not limited to, bolt connection, snap connection, key connection, pin connection, etc.

[0052] This configuration allows the reducer 1 proposed in this application to transmit power to opposite ends, resulting in higher transmission efficiency and better performance.

[0053] It should be noted that when the drive shaft connector 40 and the main shaft connector 30 are configured to mount the drive shaft 4 and the main shaft 3, the axes of the drive shaft 4 and the main shaft 3 are parallel to the axis of the drive shaft 201. For example, the axes of the drive shaft 4, the main shaft 3, and the drive shaft 201 are all parallel to each other. Figure 4 Extending in the X direction as shown, when the drive shaft connector 40 and the main shaft connector 30 are configured to be mounted on the drive shaft 4 and the main shaft 3, the axis of the drive shaft 4 and the axis of the main shaft 3 are parallel to the axis of the drive shaft 201. This eliminates the need to disconnect the photovoltaic module 200 to avoid the reducer 1, thereby improving the overall integrity of the photovoltaic system. Furthermore, this facilitates the passage of the cleaning robot, reduces the operational difficulty of the cleaning robot, and improves the cleaning quality. In addition, this reduces the risk of interference between the photovoltaic module 200 and the drive component 20 when the rotation angle is too large, allowing the photovoltaic module 200 to have a larger rotation angle to fully follow the rotation of the sun.

[0054] Therefore, by configuring the drive shaft connector 40 and the main shaft connector 30 such that when the drive shaft 4 and the main shaft 3 are installed, the axis of the drive shaft 4 and the axis of the main shaft 3 are parallel to the axis of the drive shaft 201, without having to disconnect the photovoltaic module 200, the photovoltaic system has better overall integrity and facilitates the passage of the cleaning robot, and can reduce the risk of interference between the drive component 20 and the photovoltaic module 200.

[0055] In some embodiments of this application, such as Figure 4 and Figure 9 As shown, the reducer 1 used for the photovoltaic bracket 100 further includes: a power splitting component 50, a first transmission component 60, and a second transmission component 70. The power splitting component 50 is connected to the drive shaft 201. The first transmission component 60 is connected between the power splitting component 50 and the main shaft connector 30. The second transmission component 70 is connected between the power splitting component 50 and the transmission shaft connector 40.

[0056] The reducer 1 used for the photovoltaic bracket 100 may further include: a power splitter assembly 50, a first transmission assembly 60, and a second transmission assembly 70. The power splitter assembly 50 is connected to the drive shaft 201. As some embodiments of this application, the power splitter assembly 50 is directly connected to the drive shaft 201, or the power splitter assembly 50 is connected to the drive shaft 201 through a gear pair, spline, or other transmission method.

[0057] The first transmission assembly 60 is connected between the power splitter assembly 50 and the main shaft connector 30. As some embodiments of this application, the first transmission assembly 60 can be constructed as a gear pair or a worm gear. When the first transmission assembly 60 is constructed as a gear pair, the number of gears in the gear pair can be multiple, for example, two, four, six, etc.; when the first transmission assembly 60 is constructed as a worm gear, the number of worm gear sets can be multiple, for example, one, two, three, etc.

[0058] The second transmission assembly 70 is connected between the power splitter assembly 50 and the drive shaft connector 40. As some embodiments of this application, the second transmission assembly 70 can be constructed as a gear pair or a worm gear. When the second transmission assembly 70 is constructed as a gear pair, the number of gears in the gear pair can be multiple, for example, two, four, six, etc.; when the first transmission assembly 60 is constructed as a worm gear, the number of worm gear sets can be multiple, for example, one, two, three, etc.

[0059] By setting up the power splitting component 50, the first transmission component 60, and the second transmission component 70, the power of the driving component 20 can be transmitted to the main shaft connector 30 and the transmission shaft connector 40 respectively. Thus, the main shaft connector 30 and the transmission shaft connector 40 can be driven simultaneously by one driving component 20, which can change the direction of power transmission, and has high transmission efficiency and high driving stability.

[0060] In some embodiments of this application, such as Figures 3-5 As shown, the main shaft connector 30, drive component 20, and transmission shaft connector 40 are arranged along the height direction of the reducer 1, and the height direction of the reducer 1 is perpendicular to the axial direction of the drive shaft 201.

Figure 4 As shown in the Z direction, in some embodiments of this application, along the height direction of the reducer 1, from top to bottom, the main shaft connector 30, the drive component 20, and the transmission shaft connector 40 are arranged in sequence.

[0062] This arrangement allows for a reasonable layout of the main shaft connector 30, drive component 20, and transmission shaft connector 40, eliminating the need to disconnect the photovoltaic module 200. This results in better overall integrity of the photovoltaic system and facilitates the passage of the cleaning robot. Furthermore, it allows for multiple layout options for the main shaft connector 30, drive component 20, and transmission shaft connector 40, enabling selection based on actual needs and providing greater flexibility.

In some embodiments of this application, the first transmission wheel 601 directly meshes with the main shaft connector 30 or is connected via a gear pair.

[0067] By setting up the power split transmission wheel 501 and the first transmission wheel 601, the power of the driving component 20 can be transmitted to the main shaft connector 30, so that the main shaft connector 30 can be driven simultaneously by the driving component 20. The structure is simple and reasonable, with good transmission stability and high transmission efficiency.

[0068] The second transmission assembly 70 includes a second transmission wheel 701 and a third transmission wheel 702. The third transmission wheel 702 is connected to the transmission shaft connector 40.

[0070] By setting up a power split transmission wheel 501, a second transmission wheel 701, and a third transmission wheel 702, the power of the driving component 20 can be transmitted to the transmission shaft connector 40. Thus, the driving component 20 can simultaneously drive the transmission shaft connector 40. The structure is simple and reasonable, with good transmission stability and high transmission efficiency.

[0071] This configuration allows the power of the drive component 20 to be transmitted to the main shaft connector 30 and the transmission shaft connector 40 respectively. Thus, the main shaft connector 30 and the transmission shaft connector 40 can be driven simultaneously by one drive component 20. Furthermore, the structure is simple and reasonable, with good transmission smoothness and high transmission efficiency. In addition, the power splitting component 50, the first transmission component 60 and the second transmission component 70 can all be set inside the support 10, improving the structural compactness of the reducer 1.

[0072] In some embodiments of this application, such as Figures 8-10 As shown, the drive component 20 and the transmission shaft connector 40 are arranged along the first direction, and the main shaft connector 30 and the drive component 20 are arranged along the height direction of the reducer 1.

As some embodiments of this application, the spindle connector 30 is located above the drive member 20 and the transmission shaft connector 40.

[0074] This configuration allows for a reasonable arrangement of the main shaft connector 30, drive component 20, and transmission shaft connector 40, eliminating the need to disconnect the photovoltaic module 200. This improves the overall integrity of the photovoltaic system and facilitates the movement of the cleaning robot. Furthermore, it allows for multiple arrangement options for the main shaft connector 30, drive component 20, and transmission shaft connector 40, providing greater flexibility to choose the appropriate configuration based on specific needs. Additionally, it reduces the overall height of the reducer 1, minimizing vertical space occupation and further reducing the risk of interference between the photovoltaic module 200 and drive component 20 during excessive rotation, thus improving the reliability of the reducer 1.

Both second connecting ends 401 have mating holes 4011, which can be fitted with the drive shaft 4 (e.g., by bolt fitting), and the drive shaft 4 can be driven to connect with the driven reducer 2. This arrangement facilitates the drive shaft 4 and the drive shaft connector 40, reducing assembly difficulty and improving assembly efficiency.

[0087] In some embodiments of this application, such as Figure 4As shown, the reducer 1 used for the photovoltaic bracket 100 includes at least one of the following:

[0088] Method 1: The support 10 defines a receiving space 103, in which at least a portion of the drive shaft 201 and at least a portion of the transmission shaft connector 40 are received;

[0089] Method 2: The support 10 has a sleeve part 101, and the main shaft connector 30 passes through the sleeve part 101 and is rotatably engaged with the sleeve part 101;

[0090] Method 3: The support 10 has a mounting part 102, which is suitable for assembly with the column 5.

[0091] In one embodiment, part or all of the drive shaft 201 is housed in the receiving space 103, and part or all of the transmission shaft connector 40 is housed in the receiving space 103. In some embodiments of this application, at least a portion of the power splitter assembly 50 is housed in the receiving space 103. In some embodiments of this application, at least a portion of the first transmission assembly 60 is housed in the receiving space 103. In some embodiments of this application, at least a portion of the second transmission assembly 70 is housed in the receiving space 103. This arrangement allows at least some of the transmission components of the reducer 1 to be integrated inside the support 10, making the overall structure of the reducer 1 compact. This reduces the risk of transmission failure caused by external foreign objects and helps extend the service life of the reducer 1.

[0092] Method 2: For example Figure 3 , Figure 5 , Figure 8 and Figure 10 As shown, the support 10 has a sleeve portion 101, through which the main shaft connector 30 passes and is rotatably engaged with the sleeve portion 101. In some embodiments of this application, along the height direction of the reducer 1, the top end of the support 10 has a sleeve portion 101, through which the main shaft connector 30 passes. In other words, the sleeve portion 101 is used to accommodate the portion of the main shaft connector 30, and the main shaft connector 30 is rotatable relative to the sleeve portion 101. This arrangement makes the structure of the support 10 reasonable, facilitates the installation of the main shaft connector 30, and facilitates the fixing of the main shaft connector 30 to the main shaft 3.

[0093] Method 3: The support 10 has a mounting portion 102, which is adapted to be assembled with the column 5. As some embodiments of this application, the bottom of the support 10 has a mounting portion 102 along the height direction of the reducer 1. The number of mounting portions 102 can be multiple, for example, two, four, six, etc. The mounting portion 102 can be assembled with the column 5 to securely fix the reducer 1 to the column 5.

[0094] The photovoltaic bracket 100 according to an embodiment of this application includes the aforementioned reducer 1 for the photovoltaic bracket 100. By configuring the drive shaft connector 40 and the main shaft connector 30 such that the axis of the drive shaft 4 and the axis of the main shaft 3 are parallel to the axis of the drive shaft 201 when the drive shaft 4 and the main shaft 3 are mounted, it is not necessary to disconnect the photovoltaic module 200. This improves the overall integrity of the photovoltaic system, facilitates the passage of the cleaning robot, and reduces the risk of interference between the drive component 20 and the photovoltaic module 200.

[0095] In some embodiments of this application, the photovoltaic support 100 further includes: a main shaft 3, a driven reducer 2, and a transmission shaft 4. Along the axial direction of the drive shaft 201, driven reducers 2 are arranged at both ends of the reducer 1. The main shaft connector 30 is driven to both ends of the main shaft 3, and the two main shafts 3 are driven to the two driven reducers 2 respectively. The transmission shaft connector 40 is driven to both ends of the transmission shaft 4, and the two transmission shafts 4 are driven to the two driven reducers 2 respectively. The reducer 1 can directly drive the main shaft 3 to rotate, and the reducer 1 can drive the driven reducer 2 through the transmission shaft 4, so as to drive the main shaft 3 to rotate through the driven reducer 2. This arrangement allows the main shaft 3 to be supported at multiple positions, thereby reducing the risk of minor deformation in the middle part of the main shaft 3, improving the stability of power transmission, and also allowing the main shaft 3 to be driven from multiple positions simultaneously, improving the smoothness of the rotation of the main shaft 3.

[0096] As some embodiments of this application, the two driven reducers 2 may have the same structure.

[0097] The photovoltaic system according to the embodiments of this application includes the photovoltaic bracket 100 described above. By configuring the drive shaft connector 40 and the main shaft connector 30 such that when the drive shaft 4 and the main shaft 3 are mounted, the axis of the drive shaft 4 and the axis of the main shaft 3 are parallel to the axis of the drive shaft 201, eliminating the need to disconnect the photovoltaic module 200. This improves the overall integrity of the photovoltaic system, facilitates the passage of the cleaning robot, and reduces the risk of interference between the drive component 20 and the photovoltaic module 200.
