[0027] 1. In the present application, the first hoop can be locked to the main shaft by a U-shaped first hoop and a throat hoop, and there is no need to set another hoop to fix the first hoop on the main shaft, which effectively reduces the number of other structural parts, fasteners and other parts, and the structure is simpler, which is conducive to on-site installation.

When the main shaft and the synchronous shaft rotate synchronously, the main shaft rotates in the first hoop and the suspension frame, and the synchronous shaft rotates in the fixed frame.

At the same time, the fixed frame can also support the synchronous shaft, making the overall rotation of the synchronous shaft more stable.

[0028] 2. In the present application, rolling contact is adopted between the arc rail and the first connecting part, which effectively reduces the friction resistance between the arc rail and the first connecting part when the main shaft drives the arc rail to rotate, improves the smoothness of relative sliding between the arc rail and the first connecting part, and further reduces the possibility of the fixed frame following the movement of the arc rail, ensuring that the center rotation of the synchronous shaft will not change with the main shaft.

[0029] 3. In the present application, when assembling the suspension frame and the fixing frame, it is only necessary to insert the suspension frame between the two first docking parts of the fixing frame, without the need to set up an additional connection structure.

[0045] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0046] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0047] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0048] In this document, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integral connection; or it can be a mechanical connection, or it can be an electrical connection; or it can be a direct connection, or it can be indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] In the embodiments shown in the drawings, directional indications (such as up, down, left, right, front, and back, etc.) are not absolute but relative when describing the structure and movement of each component, and are not used to limit the direction of the product in actual use.

[0050] In addition, in the description of the present application, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe related objects, and cannot be understood as indicating or implying the relative importance or order between the related objects.

[0051] According to an example embodiment provided by this application, see Figures 1 to 5A synchronous shaft fixing suspension structure is used to suspend and fix the synchronous shaft 700 on the main shaft 600, and specifically may include a first clamp 100, a throat clamp 200, a suspension frame 300 and a fixing frame 400. The first clamp 100 is a U-shaped plate structure, having a relative concave surface and a convex surface, the concave surface is suitable for fitting the outer wall of the main shaft 600, and the convex surface is the side of the first clamp 100 away from the main shaft 600; and the first clamp 100 is formed with a first end 110 and a second end 120 at the U-shaped opening. The throat clamp 200 is sleeved outside the first clamp 100 and the main shaft 600 to lock the first clamp 100 to the main shaft 600. The suspension frame 300 includes an arc-shaped rail 310, and the two ends of the arc-shaped rail 310 in the arc length direction are respectively connected to the first end 110 and the second end 120 of the first clamp 100. The arc-shaped rail 310 and the first clamp 100 are combined to form an installation space for the main shaft 600 to pass through. The fixing frame 400 is connected to the synchronous shaft on one hand, and is installed on the arc-shaped rail 310 on the other hand and can move on the arc-shaped rail 310.

[0052] This embodiment utilizes the sliding setting between the arc rail 310 and the fixing frame 400, so that during the rotation of the main shaft 600, only the first clamp 100, the throat clamp 200 and the suspension frame 300 follow the main shaft 600 to rotate around the central axis of the main shaft 600, and the fixing frame 400 used to carry the synchronous shaft 700 will not be affected by the rotation of the main shaft 600. In this way, the central rotation of the synchronous shaft 700 installed in the fixing frame 400 will not change with the main shaft 600, which effectively solves the problem of excessive deflection of the synchronous shaft 700 due to the increase in the span of the column, and the appearance is more beautiful. Under the same structural and performance requirements, the gap between the columns can be set larger, effectively reducing the cost of the columns. Moreover, the fixing frame 400 in this embodiment can also play a role in supporting the synchronous shaft 700, so that the overall rotation of the synchronous shaft 700 is more stable, which is conducive to the long-term stable operation of the photovoltaic bracket.

[0053] Among them, the arc rail 310 is specifically an arc segment structure with the central axis of the main shaft 600 as the central axis, which can effectively avoid mutual interference between the main shaft 600 and the synchronous shaft 700 during rotation. At the same time, the relative sliding between the arc rail 310 and the fixed frame 400 is also smoother, and the structural setting is reasonable and practical.

[0054] In addition, the present embodiment uses a U-shaped first clamp 100 to connect the hanger 300 to the main shaft 600, and the first clamp 100 can be directly installed on the main shaft 600 through the throat clamp 200, which has a simple structure and is easy to install. The throat clamp 200 adopts an open inner and outer ring structure and is locked with bolts, which can be applied to first clamps 100 and main shafts 600 of various sizes, and the appearance after assembly is also more beautiful.

[0055] Specifically, the fixing frame 400 includes a bearing portion 410 and a first connecting portion 420 disposed on the bearing portion 410. The bearing portion 410 is used to bear the synchronous shaft 700. The first connecting portion 420 is hung on the arc rail 310, and the first connecting portion 420 can slide relative to the arc rail 310 along the extending direction of the arc rail 310.

[0056] For example, there are two first connecting parts 420, which are respectively arranged on both sides of the bearing part 410 in the extending direction of the synchronization shaft 700. A rod may be connected between the two first connecting parts 420, and the rod is preferably cylindrical. The arc rail 310 passes through the gap formed between the two first connecting parts 420 and the rod, so that the arc rail 310 and the fixing frame 400 can slide relative to each other.

[0057] Of course, in actual production, the two docking parts, the rod and the bearing 500 provided in this embodiment can be made by integral molding.

[0058] In a preferred embodiment, see Figures 3 to 5 A roller 430 may be further provided between the two first connecting parts 420. The roller 430 can roll in contact with the arc rail 310 when the arc rail 310 and the fixing frame 400 slide relative to each other, thereby reducing the friction resistance between the arc rail 310 and the fixing frame 400, so as to improve the smoothness of the relative sliding between the arc rail 310 and the fixing frame 400, reduce the possibility that the fixing frame 400 follows the movement of the arc rail 310, and make the central rotation of the synchronization shaft 700 not change with the main shaft 600, further reducing the mutual influence between the main shaft 600 and the synchronization shaft 700 when they rotate synchronously.

[0059] In all the above embodiments, a gap can be formed on the fixing frame 400 for the arc rail 310 to pass through. In this way, when assembling the hanging frame 300 and the fixing frame 400, it is only necessary to insert the hanging frame 300 between the two first connecting parts 420 of the fixing frame 400, and no additional connecting structure is required. That is, in the installation process of the entire synchronous shaft 700 fixing the hanging structure, only when the arc rail 310 is installed to the first clamp 100, fasteners may be required, and the number of parts is small and not easy to be lost, which is conducive to on-site installation.

[0060] Specifically, the arc rail 310 has a second connection portion 320 at both ends in the arc length direction, which is used to install the hanger 300 on the first clamp 100. The arc rail 310 and the second connection portion 320 preferably form a U-shaped structure together, which is more conducive to inserting the hanger 300 between the two first connection portions 420 of the fixing frame 400 during assembly, and is easy to install.

[0061] Specifically, see Figures 1 to 5The first end 110 and the second end 120 of the first clamp 100 are bent outward to form a first docking portion 130 and a second docking portion 140, respectively, and mounting holes are provided on the first docking portion 130 and the second docking portion 140. At the same time, the second connecting portion 320 in this embodiment is preferably a screw structure, and the second connecting portions 320 located at both ends of the arc rail 310 pass through the mounting holes on the first docking portion 130 and the mounting holes on the second docking portion 140, respectively, and are installed on the first docking portion 130 and the second docking portion 140 through the locking nut 330, so as to fix the arc rail 310 in the U-shaped opening direction of the first clamp 100, and the installation is convenient and fast.

[0062] The opening direction of the arc rail 310 is arranged opposite to the U-shaped opening direction of the first clamp 100 , so that the arc rail 310 and the first clamp 100 are combined to form an installation space for the main shaft 600 to pass through.

[0063] As a preference, see Figure 1 and Figure 2 Each second connection part 320 corresponds to two locking nuts 330, and the two locking nuts 330 are respectively located on both sides of the first docking part 130 or the second docking part 140 in the extension direction of the second connection part 320, so as to lock the second connection part 320 to the first docking part 130 or the second docking part 140, so that the connection between the second connection part 320 and the first docking part 130, the second docking part 140 is more stable and not easy to loosen due to shaking or vibration.

[0064] Further, see Figure 3 and Figure 4 The first end 110 and the second end 120 of the first clamp 100 are both provided with a stopper 150. There are gaps between the stopper 150 at the first end 110 and the first docking portion 130, and between the stopper 150 at the second end 120 and the second docking portion 140, which can form a limiting groove 160 suitable for placing the throat clamp 200 to limit the displacement of the throat clamp 200 along the extension direction of the main shaft 600, so that the throat clamp 200 is not easily separated from the first clamp 100 due to external factors such as vibration during the rotation of the main shaft 600, thereby ensuring a stable connection between the first clamp 100 and the main shaft 600. Among them, the first clamp 100 is preferably made of one-piece molding.

[0065] Further, see Figures 1 to 4 Ribs 170 are provided between the convex surface of the first clamp 100 and the first docking portion 130 and between the convex surface and the second docking portion 140, which can enhance the structural strength of the first clamp 100 so that the first clamp 100 can better support the fixing frame 400 and the synchronization shaft 700. The structural setting is reasonable and practical.

[0066] For example, see Figures 1 to 4The bearing portion 410 includes a bearing sleeve 411, in which a bearing assembly 500 is installed, and the bearing assembly 500 further includes a bearing 510, a first stop shoulder 520, and a second stop shoulder 530. The first stop shoulder 520 and the second stop shoulder 530 are respectively connected to both sides of the bearing 510 in the axial direction and extend in a direction away from the axial direction of the bearing 510, thereby abutting against both ends of the bearing sleeve 510 in the extending direction of the synchronous shaft 700, so that the bearing sleeve 411 is clamped between the first stop shoulder 520 and the second stop shoulder 530, and then the bearing 500 is clamped on the bearing portion 410 through the first stop shoulder 520 and the second stop shoulder 530.

[0067] In this embodiment, the bearing 510 can rotate around its own axis relative to the bearing sleeve 411, and the bearing 510 is provided with a bearing hole for the synchronous shaft 700 to penetrate. In this embodiment, by providing the bearing 500, the synchronous shaft 700 can rotate more smoothly and without jamming, which is conducive to the synchronous rotation of the main shaft 600 and the synchronous shaft 700.

[0068] Specifically, the first shoulder 520 is formed on one side of the bearing 510 in the axial direction, and the second shoulder 530 is detachably connected to the other side of the bearing 510 in the axial direction, which is beneficial to the assembly between the bearing assembly 500 and the bearing portion 410 .

[0069] In one example embodiment, see Figure 5 The bearing portion 410 may include a second clamp 412 and a third clamp 413 , and the second clamp 412 and the third clamp 413 together form a chamber capable of accommodating the synchronization shaft 700 , and the bearing assembly 500 is installed in the chamber 700 .

[0070] The bearing assembly 500 includes a first half bearing 540 and a second half bearing 550. The first half bearing 540 is provided with a first shoulder 520 and a second shoulder 530 on both axial sides thereof, which are away from the first half bearing 540 in the axial direction. Meanwhile, the second half bearing 550 is also provided with a first shoulder 520 and a second shoulder 530 on both axial sides thereof, which are away from the second half bearing 550 in the axial direction. The first shoulder 520 and the second shoulder 530 can respectively abut against two ends of the bearing part 410 in the extending direction of the synchronous shaft 700, so that the bearing part 410 is clamped between the first shoulder 520 and the second shoulder 530, and then the first half bearing 540 and the second half bearing 550 are clamped on the bearing part 410 through the corresponding first shoulder 520 and the second shoulder 530.

[0071] This embodiment adopts a split bearing. During assembly, the first half bearing 540 can be first clamped into one of the second clamp 412 and the third clamp 413, and the second half bearing 550 can be clamped into the other of the second clamp 412 and the third clamp 413. Subsequently, the second clamp 412 and the third clamp 413 are fixedly connected to achieve the assembly between the load-bearing part 410 and the bearing assembly 500, which is easy to install.

[0072] The split bearing structure provided in this embodiment can form a bearing hole between the first half bearing 540 and the second half bearing 550 for the synchronization shaft 700 to pass through. When the synchronization shaft 900 rotates, the first half bearing 540 and the second half bearing 550 can also rotate relative to the second clamp 412 and the third clamp 413, thereby improving the smoothness of the rotation of the synchronization shaft 700.

[0073] See also Figures 3 to 5 The present invention also provides a photovoltaic bracket, which may specifically include a column, a driving mechanism, a main shaft 600, a synchronous shaft 700 and a synchronous shaft fixing suspension structure provided in any of the above embodiments.

[0074] Specifically, the main shaft 600 is rotatably mounted on the top of the column to carry and drive the photovoltaic panel to rotate. The driving mechanism is mounted on the column, and the main shaft 600 and the synchronous shaft 700 are connected to the driving mechanism. The driving mechanism is used to drive the main shaft 600 and the synchronous shaft 700 to rotate synchronously, and the synchronous shaft 700 is located below the main shaft 600. The first clamp 100 is installed on the side of the main shaft 600 away from the synchronous shaft 700 through the throat clamp 200, and the fixing frame 400 is installed below the first clamp 100 through the suspension frame 300, and the synchronous shaft 700 is set through the fixing frame 400.

[0075] Because the suspension frame 300 and the fixing member in this embodiment can slide relative to each other, when the main shaft 600 and the synchronous shaft 700 rotate synchronously, the main shaft 600 rotates in the first hoop 100 and the suspension frame 300, and the synchronous shaft 700 rotates in the bearing portion 410. The two do not interfere with each other, and the central rotation of the synchronous shaft 700 will not change with the main shaft 600, which effectively solves the problem of excessive deflection of the synchronous shaft 700 due to the increase in the span of the column, and the appearance is more beautiful. At the same time, the bearing portion 410 can also play a role in supporting the synchronous shaft 700, making the overall rotation of the synchronous shaft 700 more stable, which is conducive to the long-term stable operation of the photovoltaic bracket and has strong practicality.

[0076] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0077] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
