[0029] Please see Figures 1 to 8 As shown, this embodiment discloses a control box mounting structure suitable for assembling the control box 10 onto the spindle 20. The control box mounting structure includes a clamp assembly 1 and a mounting base 2. The clamp assembly 1 surrounds the outer periphery of the spindle 20, and the mounting base 2 is fixedly connected to the clamp assembly 1 and the control box 10.

[0030] Please see Figures 4 to 6As shown, the control box mounting structure also includes a rotating pin 3 and a first connecting assembly 4. The clamp assembly 1 includes an upper connecting seat 11 and a lower connecting seat 12. One end of the upper connecting seat 11 is rotatably connected to one end of the lower connecting seat 12 via the rotating pin 3, and the other end of the upper connecting seat 11 is detachably fixedly connected to the other end of the lower connecting seat 12 via the first connecting assembly 4. With this configuration, one side of the clamp assembly 1 can be rotated open and closed, and the control box 10 can be quickly installed by locking it on one side, making installation and removal convenient.

[0031] Please see Figure 4 , Figure 6 and Figure 7 As shown, the upper connecting seat 11 includes an upper support portion 111 and a first adapter portion 112 and a first fixed portion 113 respectively disposed at both ends of the upper support portion 111. The lower connecting seat 12 includes a lower support portion 121 and a second adapter portion 122 and a second fixed portion 123 respectively disposed at both ends of the lower support portion 121. The upper support portion 111 and the lower support portion 121 at least partially abut against the main shaft 20 to achieve a limiting connection between the clamp assembly 1 and the main shaft 20. The first adapter portion 112 and the second adapter portion 122 are rotatably connected to allow one side of the clamp assembly 1 to be rotatably opened and closed. The first fixed portion 113 and the second fixed portion 123 are fixedly connected to allow the clamp assembly 1 to be locked and fixed to the main shaft 20 via the other side.

[0032] Please see Figures 3 to 8 As shown, the first connecting assembly 4 includes a first connecting portion 41, a second connecting portion 42, and a limiting member 43. The first connecting portion 41 passes through the other end of one of the upper connecting seat 11 and the lower connecting seat 12 and connects to the second connecting portion 42. The second connecting portion 42 extends to the other end of the other of the upper connecting seat 11 and the lower connecting seat 12 and is locked and fixed by the limiting member 43. In this embodiment, the first connecting portion 41 is a pin, the second connecting portion 42 is a hinge bolt, and the limiting member 43 is a nut. The pin passes through the hinge bolt, and the axial direction of the rotating pin 3 is parallel to the axial direction of the pin. The first adapter portion 112 and the second adapter portion 122 can rotate about the axial direction of the rotating pin 3, and the hinge bolt can rotate about the axial direction of the pin.

[0033] Please see Figures 4 to 6As shown, in one embodiment, the first adapter 112 includes two first convex shafts 114 spaced apart along the axial direction of the rotating pin 3. Each first convex shaft 114 has a first through hole 115. The second adapter 122 includes a hook portion 124. The rotating pin 3 passes through the first through holes 115 of the two first convex shafts 114. The hook portion 124 hooks onto the rotating pin 3 and is at least partially located between the two first convex shafts 114. Further, the diameter of the first through hole 115 is adapted to the diameter of the rotating pin 3, the portion of the hook portion 124 hooking onto the rotating pin 3 is adapted to the rotating pin 3, and the length of the hook portion 124 along the axial direction of the rotating pin 3 is equal to the distance between the two first convex shafts 114, meaning that both ends of the hook portion 124 along the axial direction of the rotating pin 3 abut against the two first convex shafts 114 respectively. This configuration enables a rotatable connection between the upper connecting seat 11 and the lower connecting seat 12. The convex shaft 114 and / or the hook 124 can rotate around the axial direction of the rotating pin 3, and the hook 124 will not undergo axial displacement.

[0034] Please see Figure 7 and Figure 8 As shown, in another embodiment, the first adapter 112 includes two first convex shafts 114 spaced apart along the axial direction of the rotating pin 3. Each first convex shaft 114 has a first through hole 115. The second adapter 122 includes a frustum 125 with a second through hole 126. The rotating pin 3 passes through the two first through holes 115 and the second through hole 126, and the frustum 125 is at least partially located between the two first convex shafts 114. Further, the diameters of the first through holes 115 and the second through holes 126 are adapted to the diameter of the rotating pin 3, and the length of the frustum 125 along the axial direction of the rotating pin 3 is equal to the distance between the two first convex shafts 114, meaning that the two ends of the frustum 125 along the axial direction of the rotating pin 3 respectively abut against the two first convex shafts 114. This configuration enables a rotatable connection between the upper connecting seat 11 and the lower connecting seat 12, allowing the convex shaft 114 and / or the frustum 125 to rotate axially around the rotating pin 3, without any axial displacement of the frustum 125.

[0035] Please see Figures 4 to 8As shown, the first fixed connection portion 113 includes two second convex shafts 116 spaced apart along the axial direction of the pin. Each second convex shaft 116 has a third through hole 117, and the second fixed connection portion 123 has a notch 127. The pin passes through the third through holes 117 of the two second convex shafts 116 and a hinge bolt. The hinge bolt corresponds vertically to the notch 127, extending into the notch 127. A nut locks the hinge bolt onto the side of the notch 127 opposite to the upper connecting seat 11. Furthermore, the diameter of the third through hole 117 and the diameter of the hinge bolt are both adapted to the diameter of the pin, and the hinge bolt is located between the two second convex shafts 116. The two ends of the hinge bolt along the axial direction of the pin respectively abut against the two second convex shafts 116. This configuration enables a fixed connection between the upper connecting seat 11 and the lower connecting seat 12. After the clamp assembly 1 is positioned around the outer periphery of the main shaft 20, the first fixed part 113 and the second fixed part 123 are locked and fixed by the first connecting assembly 4 to fix the entire clamp assembly 1 to the main shaft 20. The hinge bolt will not be displaced axially along the pin shaft and can smoothly cooperate with the notch 127.

[0036] Furthermore, the notch 127 extends to the side of the second fixed part 123 away from the second transition part 122, and the width of the notch 127 is not less than the diameter of the shank of the hinge bolt, so as to provide space for the hinge bolt to rotate with the upper connecting seat 11.

[0037] Please see Figures 1 to 3 , Figure 5 As shown, two mounting bases 2 are integrally disposed on both sides of the control box 10 to improve the installation stability of the control box 10 on the spindle 20. The control box mounting structure of this embodiment also includes a second connecting component 5. The lower connecting base 12 has a first mounting hole 13, and the mounting base 2 has a second mounting hole 21. The second connecting component 5 passes through the first mounting hole 13 and the second mounting hole 21 and is locked in place. With this configuration, the clamp assembly 1 is installed on the spindle 20, and the mounting base 2 and control box 10 are integrally disposed, reducing the number of on-site installation parts and simplifying the installation process. In this embodiment, the second connecting component 5 is a bolt assembly.

[0038] Please see Figures 3 to 8As shown, the lower connecting seat 12 has a protrusion 14, which is located on one side of the lower connecting seat 12, making the two ends of the control box mounting structure asymmetrical. One of the first mounting holes 13 of the lower connecting seat 12 is located in the protrusion 14. This arrangement makes the control box 10 eccentrically positioned relative to the lower connecting seat 12 to avoid interference between the control box 10 and the synchronous shaft. In the photovoltaic bracket, the control box 10 is installed near the rotary motor. When the active rotary motor is installed in the middle of the bracket, there are synchronous shafts on both sides of the rotary motor. If the control box 10 is symmetrically installed on the lower connecting seat 12, it will collide with the synchronous shaft when it rotates synchronously with the main shaft 20. In this embodiment, the control box 10 is eccentrically positioned, which increases the distance between the synchronous shaft and the control box 10, thus avoiding interference during rotation.

[0039] Please see Figures 4 to 8 As shown, the upper support portion 111 has a first perforated hole 118, and / or the lower support portion 121 has a second perforated hole 128. This arrangement reduces the weight of the upper connecting seat 11 and / or the lower connecting seat 12, thereby reducing the overall weight of the control box mounting structure and further facilitating installation and disassembly. Furthermore, the first perforated hole 118 is provided with reinforcing ribs, so that the first perforated hole 118 is not through, to ensure structural strength, so that the clamp assembly 1 has sufficient strength to bear the weight of the control box 10 and support the main shaft 20.

[0040] In this embodiment, both the upper connecting seat 11 and the lower connecting seat 12 are injection molded, which further reduces weight and lowers production costs while ensuring connection strength. Furthermore, to ensure the connection strength between the upper connecting seat 11 and the lower connecting seat 12, an iron plate is provided on the side of the notch 127 away from the upper connecting seat 11, i.e., where the nut is locked against the second fixed part 123. This arrangement makes the hinge bolt more secure after being locked with the nut.

[0041] The control box mounting structure of this embodiment can be pre-assembled as a whole. Specifically, the lower connecting seat 12 is assembled with the integrally set mounting seat 2 and control box 10. At the same time, the upper connecting seat 11 and the lower connecting seat 12 are rotatably connected by the rotating pin 3, and the first connecting component 4 is assembled on the upper connecting seat 11. At the project site, it is only necessary to rotate and open the upper connecting seat 11 and the lower connecting seat 12 to fit around the outer circumference of the main shaft 20. After slightly loosening the nut in the first connecting component 4, the hinge bolt can rotate with the upper connecting seat 11 and be inserted into the notch 127. Then, tighten the nut to complete the installation.

[0042] In other embodiments, the first connecting part 41 and the second connecting part 42 in the first connecting assembly 4 can be T-shaped connectors. The first connecting part 41 and the second connecting part 42 are integrally formed and have an overall T-shaped structure. The second connecting part 42 is provided with threads, and the limiting member 43 is a nut that engages with the thread on the second connecting part 42 to limit the first connecting assembly 4. In other embodiments, the limiting member 43 can also be an anti-loosening washer or a limiting pin that engages with the second connecting part 42, or the limiting member can be achieved by providing a mutually cooperating buckle structure on one of the first connecting assembly 4, the upper connecting seat 11, or the lower connecting seat 12 to prevent loosening.

[0043] In summary, compared with the prior art, the control box mounting structure of this utility model has the following advantages: The control box mounting structure includes a clamp assembly 1, a mounting base 2, a rotating pin 3, and a first connecting assembly 4. The clamp assembly 1 includes an upper connecting base 11 and a lower connecting base 12 surrounding the outer periphery of the main shaft 20. One end of the upper connecting base 11 is rotatably connected to one end of the lower connecting base 12 by the rotating pin 3, and the other end of the upper connecting base 11 is detachably fixedly connected to the other end of the lower connecting base 12 by the first connecting assembly 4. The mounting base 2 is fixedly connected to the lower connecting base 12 and the control box 10. By designing the clamp assembly 1 to rotate and open on one side and lock on the other side, the control box 10 can be quickly installed, making disassembly and assembly convenient and reducing maintenance costs. The first connecting assembly 4 includes a first connecting part 41, a second connecting part 42, and a limiting member 43. The first connecting part 41 is disposed on the upper connecting seat 11 or the lower connecting seat 12 and connects to the second connecting part 42. The second connecting part 42 and the limiting member 43 are locked and fixed to the lower connecting seat 12 or the upper connecting seat 11. All components can be pre-installed together, reducing the number of parts on site and improving installation efficiency. The overall structure of this control box is compact and occupies little space, allowing the control box 10 to be installed in any location without restriction.
