[0009] A driving part for driving the rotating part to rotate. During the process that the rotating part rotates one week, it passes through opposite first and second positions. When the rotating part is at the first position, the moving part is at the first end of the reciprocating stroke, and the main shaft connecting part rotates to the first angle; when the rotating part is at the second position, the moving part is at the second end of the reciprocating stroke, and the main shaft connecting part rotates to the second angle.

[0026] The beneficial effects of the embodiments of the present application are as follows: The main shaft adjustment assembly provided by the present application includes a main shaft connection portion, a transmission portion, and a driving portion.

[0027] When the main shaft connection portion has a mounting hole, the mounting hole is located within the circumference surrounded by the first transmission teeth, and the connection positions between the main shaft connection portion and the main shaft are evenly distributed on the outer periphery of the mounting hole. After one end of the main shaft is inserted into the mounting hole, it is equivalent that the connection position between the main shaft connection portion and the main shaft is located on the outer periphery of the main shaft. Thus, when the main shaft connection portion drives the main shaft to rotate, the force application point of the main shaft is located on the outer periphery of the main shaft, ensuring the force arm of the main shaft rotation and reducing the output power of the driving portion.

[0046] References to "embodiments" in this specification mean that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase does not necessarily refer to the same embodiment at every occurrence in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0047] Please refer to Figures 1 to 2 , the embodiment of the present application provides a spindle adjustment assembly 100, which can be applied to a photovoltaic support to adjust the angle of a spindle 200. The spindle adjustment assembly 100 includes a spindle connection portion 10, a transmission portion, and a driving portion 30. Among them, the spindle connection portion 10 is used for fixedly connecting with the spindle 200, and the spindle connection portion 10 has a first transmission tooth 11. The transmission portion includes a moving member 21 and a rotating member 22. The moving member 21 has a second transmission tooth 211a, and the second transmission tooth 211a cooperates with the first transmission tooth 11. When the rotating member 22 is driven, it drives the moving member 21 to reciprocate. The driving portion 30 is used for driving the rotating member 22 to rotate. During one rotation of the rotating member 22, it passes through opposite first and second positions. When the rotating member 22 is in the first position, the moving member 21 is at the first end of the reciprocating stroke, and the spindle connection portion 10 rotates to a first angle; when the rotating member 22 is in the second position, the moving member 21 is at the second end of the reciprocating stroke, and the spindle connection portion 10 rotates to a second angle, so that the transmission portion drives the spindle connection portion 10 to rotate between the first angle and the second angle.

[0048] In the spindle adjustment assembly 100 provided by the embodiment of the present application, during the process that the driving part 30 drives the rotating part 22 in the transmission part to rotate one week, the rotating part 22 will pass through a first position once and a second position opposite to the first position once. It can be understood that during the process that the rotating part 22 rotates one week in one direction, it will experience moving from the first position to the second position and then returning from the second position to the first position again; since the rotating part 22 drives the moving part 21 to reciprocate, correspondingly, the rotating part 22 can drive the moving part 21 to move from the first end to the second end in its reciprocating movement stroke and then move from the second end to the first end; and since the second transmission tooth 211a on the moving part 21 cooperates with the first transmission tooth 11 on the spindle connection part 10, correspondingly, the moving part 21 can drive the spindle connection part 10 to rotate from a first angle to a second angle and then rotate from the second angle along the original rotation path to the first angle. Thus, by driving the rotating part 22 to rotate in a certain direction by the driving part 30, the reciprocating rotation of the spindle connection part 10 between the first angle and the second angle can be realized, and further the spindle connection part 10 can drive the spindle 200 thereon to rotate, realizing the angle adjustment of the photovoltaic module on the spindle 200. Among them, the direction in which the driving part 30 drives the rotating part 22 to rotate can be counterclockwise rotation or clockwise rotation. In addition, it should be noted that the first angle and the second angle of the spindle 200 connection part 10 refer to two circumferential angles in a plane perpendicular to the rotation axis of the spindle 200 connection part 10. For example, as Figure 8 shown, the circumferential angles are distributed clockwise. The first angle of the spindle connection part 10 can be 215 degrees, and the second circumferential angle can be 45 degrees. The reciprocating rotation of the spindle connection part 10 between the first angle and the second angle can be rotating from 215 degrees clockwise to 45 degrees and then rotating from 45 degrees counterclockwise to 215 degrees.

[0049] Since the driving part 30 outputs a rotational motion in a certain direction to realize the reciprocating rotation of the spindle 200 connection part 10 between the first angle and the second angle, there will be no situation of damaging the photovoltaic tracking bracket due to overtravel, which can effectively ensure the stability of the photovoltaic tracking bracket for adjusting the spindle 200. And during the process that the driving part 30 drives the rotating part 22 to rotate one week, the spindle connection part 10 can only reciprocate between the first angle and the second angle, that is, the first angle and the second angle are two limit positions for the rotation of the spindle connection part 10. Thus, when the spindle adjustment assembly 100 provided by the present application is applied to the photovoltaic tracking bracket to adjust the angle of the photovoltaic module on the spindle 200, there is no need to additionally set a limiting device, simplifying the structure of the photovoltaic tracking bracket.

[0050] It should be noted that the main shaft 200 in the photovoltaic tracking bracket is generally rotatably arranged on the photovoltaic tracking bracket. When the main shaft adjusting assembly 100 provided in the embodiment of the present application is applied to the photovoltaic tracking bracket, the main shaft connecting portion 10 of the main shaft adjusting assembly 100 is fixedly connected to the main shaft 200. It can be understood that when the main shaft connecting portion 10 drives the main shaft 200 to rotate, the rotation center of the main shaft connecting portion 10 is the rotation center of the main shaft 200.

[0051] The main shaft connecting portion 10 has a first transmission tooth 11. When the moving member 21 in the transmission portion moves, it drives the main shaft connecting portion 10 to rotate through the cooperation of the second transmission tooth 211a and the first transmission tooth 11. It can be understood that the main shaft connecting portion 10 can be a gear structure. Correspondingly, the moving member 21 can include a rack 211. Since the main shaft connecting portion 10 reciprocally rotates between a first angle and a second angle, the first transmission teeth 11 can be evenly distributed on the entire outer circumference of the main shaft connecting portion 10. Of course, the main shaft connecting portion 10 can also be an incomplete gear structure, that is, the first transmission teeth 11 are only distributed in a partial area of the outer circumference of the main shaft connecting portion 10.

[0052] As Figure 1 、 Figure 2 and Figure 4 shown, in some embodiments, the outer circumference of the main shaft connecting portion 10 is circular, and the first transmission teeth 11 are evenly distributed on the outer circumference of the main shaft connecting portion 10, that is, the main shaft connecting portion 10 is a gear structure. There are also several connecting positions 12 distributed within the circumference surrounded by the first transmission teeth 11 on the main shaft connecting portion 10. The connecting position 12 refers to the position on the main shaft connecting portion 10 where it is connected to the main shaft 200. In the embodiment of the present application, the specific connection method between the main shaft connecting portion 10 and the main shaft 200 is not limited. For example, it can be a snap connection, a threaded fastener connection, or a connection through the cooperation of a pin hole and a pin shaft. In the embodiment of the present application, taking the connection between the main shaft connecting portion 10 and the main shaft 200 by a threaded fastener as an example, through holes can be provided at the connecting position 12 of the main shaft connecting portion 10, and the threaded fastener passes through the through holes at the connecting position 12 and then connects to the main shaft 200. It can be understood that a connecting plate 13 is provided at the connecting position 12 of the main shaft connecting portion 10. Correspondingly, the through holes for the threaded fastener to pass through are opened on the connecting plate 13. To ensure the connection strength between the main shaft connecting portion 10 and the main shaft 200, the connecting plates 13 at several connecting positions 12 can be connected to each other integrally in the circumferential direction of the main shaft connecting portion 10.

[0053] In addition, it should be noted that the present application does not limit the specific number of connection positions 12 on the main shaft connection portion 10. For example, the number of connection positions 12 can be 2, 3, 4, 5, or 6. To ensure the stability of the connection between the main shaft connection portion 10 and the main shaft 200, several connection positions 12 can be evenly distributed along the circumferential direction of the main shaft connection portion 10. Of course, the specific number of connection positions 12 on the main shaft connection portion 10 can also be set according to the cross-sectional shape of the main shaft 200 connected by the main shaft connection portion 10. As Figure 4 shown, in the embodiment of the present application, taking the cross-sectional shape of the main shaft 200 as a rectangle as an example, correspondingly, the number of connection positions 12 can be 4, but it is not limited thereto.

[0054] As Figure 2 and Figure 4 shown, in some embodiments, the main shaft connection portion 10 further has a mounting hole 14. The mounting hole 14 is used for inserting one end of the main shaft 200. And the mounting hole 14 is located within the circumference surrounded by the first transmission teeth 11. At the same time, several connection positions 12 of the main shaft connection portion 10 are distributed on the outer periphery of the mounting hole 14. When the main shaft connection portion 10 is connected to the main shaft 200, one end of the main shaft 200 is inserted into the mounting hole 14. It can be understood that the shape of the mounting hole 14 corresponds to the cross-sectional shape of the main shaft 200. For example, when the cross-sectional shape of the main shaft 200 is a rectangle, correspondingly, the mounting hole 14 is a rectangular hole. The mounting hole 14 can be a through hole on the main shaft connection portion 10 or a counterbore. When the mounting hole 14 is a counterbore, the end portion of the main shaft 200 is inserted and embedded in the mounting hole 14; when the mounting hole 14 is a through hole, the main shaft 200 is arranged to penetrate through the mounting hole 14. In the embodiment of the present application, taking the mounting hole 14 as a through hole and the main shaft 200 penetrating through the mounting hole 14 as an example, by making the main shaft 200 penetrate through the main shaft connection portion 10, the size of the photovoltaic tracking bracket in the axial direction of the main shaft 200 is effectively reduced. In addition, by making several connection positions 12 of the main shaft connection portion 10 be distributed on the outer periphery of the mounting hole 14, after the main shaft 200 is matched with the mounting hole 14, it is equivalent that the connection positions 12 are also distributed on the outer periphery of the main shaft 200, that is, the connection positions 12 of the main shaft connection portion 10 and the main shaft 200 are located on the outer peripheral side of the main shaft 200. In this way, when the main shaft connection portion 10 drives the main shaft 200 to rotate, the force application point of the main shaft 200 is located on the outer periphery of the main shaft 200, ensuring the force arm for the rotation of the main shaft 200 and reducing the output power of the driving portion 30.

[0055] In the transmission portion, the rotating member 22 drives the moving member 21 to reciprocate through rotation. A crank-slider 23 mechanism can be formed between the rotating member 22 and the moving member 21. In the embodiment of the present application, the specific connection structure between the rotating member 22 and the moving member 21 is not limited. For example, in some embodiments, the rotating member 22 and the moving member 21 can be connected by a connecting rod. One end of the connecting rod is rotatably connected to the rotating member 22, and the other end of the connecting rod is rotatably connected to the moving member 21. As Figure 2 andFigure 3 As shown, in other embodiments, the rotating member 22 and the moving member 21 can also be connected with the slider 23 through the chute 212a, and correspondingly, the moving member 21 also has a chute 212a, one end of the rotating member 22 is rotatably connected with the slider 23 that cooperates with the chute 212a, and the other end of the rotating member 22 is connected with the driving unit 30. When the rotating member 22 rotates, the slider 23 is driven to move back and forth in the chute 212a, so that the slider 23 moves the moving member 21 back and forth through the chute 212a. Wherein the moving member 21 can also include a frame 212, and the frame 212 is surrounded by the chute 212a, and the frame 212 is fixedly connected with the rack 211. In the embodiment of the present application, the specific shape of the chute 212a is not limited, for example, the chute 212a can be a rectangular groove or an arc groove, and the embodiment of the present application takes the chute 212a as a rectangular groove as an example for explanation. The rotating member 22 is rotatably connected to the slider 23. The specific rotatable connection method is not limited in the embodiment of the present application. For example, the rotating member 22 may be fixedly provided with a connecting shaft 25, and the slider 23 may be rotatably sleeved on one end of the connecting shaft 25 away from the rotating member 22. To prevent the slider 23 from being separated from the connecting shaft 25, a stopper 24 is further provided at one end of the slider 23 away from the rotating member 22. The stopper 24 is fixedly provided on the end surface of the connecting shaft 25 by a threaded fastener to prevent the slider 23 from being separated from the connecting shaft 25.

[0056] like Figure 2 As shown, in some embodiments, the spindle adjustment assembly 100 also includes a mounting portion 40. The mounting portion 40 can be used to load the drive unit 30 and the transmission unit. The moving member 21 in the transmission unit can be movably arranged on the mounting portion 40. To ensure the stability of the movement of the moving member 21, one of the mounting portion 40 and the moving member 21 is provided with a guide groove, and the other is provided with a guide protrusion 41 that cooperates with the guide groove. In the embodiment of the present application, the guide groove is provided on the moving member 21, and the guide protrusion 41 is provided on the mounting portion 40 as an example for explanation, wherein the moving member 21 can also include a support block 213 fixedly arranged below the rack 211, and the guide groove is formed on the support block 213.

[0057] like Figure 1 and Figure 5As shown, in some embodiments, the driving part 30 has two opposite output shafts. Each output shaft is connected to a transmission part, and each transmission part is correspondingly provided with a main shaft connecting part 10. The driving part 30 can be a two-shaft motor. Since when the main shaft adjusting assembly 100 is connected to one end of the main shaft 200, the length of the main shaft 200 connected to the main shaft connecting part 10 is limited. By making the driving part 30 have two opposite output ends, and the two output ends are respectively connected to a main shaft 200 through the correspondingly arranged main shaft connecting parts 10, the number of photovoltaic modules that can be adjusted by adding a set of main shaft adjusting assemblies 100 is increased, and the utilization rate of the main shaft adjusting assembly 100 is improved. It should be noted that when the driving part 30 has two opposite output shafts, it can be understood that the rotation directions of the two output shafts are the same, or the rotation directions of the main shaft connecting parts 10 at both ends finally driven by them are the same.

[0058] As Figure 1 shown, in some embodiments, the present application further provides a photovoltaic tracking bracket. The photovoltaic tracking bracket includes a main shaft 200 and the main shaft adjusting assembly 100 in the above embodiments. The main shaft connecting part 10 of the main shaft adjusting assembly 100 is fixedly connected to the main shaft 200. The main shaft 200 is used for installing photovoltaic modules.

[0059] For the convenience of installing the photovoltaic module on the main shaft 200, purlins 201 can also be provided on the main shaft 200. The photovoltaic module is installed on the main shaft 200 by being fixed to the purlins 201. It can be understood that in the photovoltaic tracking bracket, the rotation of the main shaft connecting portion 10 between the first angle and the second angle can drive the main shaft 200 to rotate reciprocally, and thus the angle adjustment of the photovoltaic module on the main shaft 200 can be realized. And it should be noted that in some embodiments, when the main shaft connecting portion 10 further has a mounting hole 14, the mounting hole 14 is located within the circumference formed by the first transmission teeth 11, and a plurality of connecting positions 12 are evenly distributed on the outer periphery of the mounting hole 14, and mounting blocks 202 corresponding to the plurality of connecting positions 12 are provided on the outer periphery of the main shaft 200. It can be understood that the connection between the connecting position 12 of the main shaft connecting portion 10 and the main shaft 200, that is, the connecting position 12 is fixedly connected to the mounting block 202, and can also be snap connection, connection by threaded fasteners or connection by the cooperation of a pin hole and a pin shaft, but is not limited thereto. Among them, for snap connection, one of the connecting position 12 and the mounting block 202 can have a snap groove, and the other can have a snap protrusion.
