[0001] The present invention belongs to the technical field of photovoltaic supports, and in particular relates to a photovoltaic support structure. Background Art

[0002] Traditional photovoltaic mounting systems are often difficult to install and adjust. Adjusting the tilt angle of the photovoltaic panels, in particular, requires complex tools and takes a long time. This inconvenience not only increases installation and maintenance costs but also limits the flexibility and adaptability of photovoltaic systems, especially when dealing with varying terrain and lighting conditions.

[0003] To address these issues, various improved photovoltaic rack designs have emerged on the market. However, existing solutions still fail to fully meet the dual demands of convenience and stability.

The press-adjustment component can drive the support shaft 12 to rotate, thereby adjusting the inclination angle of the photovoltaic panel 3.

[0035] In an embodiment of the present invention, through the installation arrangement of the fixed frame 1, the support frame 6 and the main support frame 5, the position of the support frame 6 on the fixed frame 1 and the position of the main support frame 5 on the support frame 6 can be conveniently adjusted to meet the needs of flexible installation; the connection ear seat 11, the support shaft 12 and the load plate 2 are limited to provide stable support for the photovoltaic panel 3, and at the same time, the arrangement of the curved support frame 13 can improve the stability of the support for the load plate 2. The specially defined push-to-adjust component can fix the support shaft 12 and the curved support frame 13 when there is no external force, so that the load plate 2 remains in a stable state without shaking; when the push-to-adjust component is pressed, the push-to-adjust component releases the fixed state of the support shaft 12 and the curved support frame 13, and then the push-to-adjust component is rotated. The push-to-adjust component can drive the support shaft 12 to rotate, thereby adjusting the inclination angle of the photovoltaic panel 3, that is, the press + rotation method is used to unlock and adjust the angle, which significantly improves the convenience of adjustment. After the adjustment is completed, it can be restored to the locked state without additional operation. It has high reliability and wide application.

[0036] like Figure 1-3 As shown in FIG. 1 , as a preferred embodiment of the present invention, the support frame 6 is fixed with reverse U-shaped clips 7 on the lower sides of both ends. The reverse U-shaped clips 7 can be positioned on the fixed frame 1.

After adjusting the position of the main body support frame 5 on the support frame 6, it can be locked and fixed by the fastening bolts 10, which is stable and convenient.

[0038] like Figure 3-7 As shown, as a preferred embodiment of the present invention, the press adjustment assembly includes a bevel gear 12 installed and fixed on the support shaft 12, and the inner side of the adjustment seat body 4 is rotatably provided with a drive shaft 24, one end of the drive shaft 24 is fixed with a bevel gear 23 meshing with the bevel gear 12, and the other end of the drive shaft 24 is slidably provided with a polygonal drive rod 26, and the end of the polygonal drive rod 26 away from the drive shaft 24 is fixed with an adjustment shaft 15, and the adjustment shaft 15 is connected to the adjustment seat body 4 for sliding and rotation, and the end of the adjustment shaft 15 away from the polygonal drive rod 26 is fixed with a control knob 14, and the polygonal drive rod 26 is also provided with a spring 125; the inner lower part of the main support frame 5 The sliding part is provided with a positioning block 35 for abutting and fixing the curved support frame 13, and the upper end of the positioning block 35 is fixed with a contact plate 33, and the lower side of the contact plate 33 is provided with a spring 2 34 for elastic support thereof. A support shaft 2 31 is rotatably provided in the main support frame 5 between the support shaft 12 and the contact plate 33, and a cam 30 that abuts and cooperates with the contact plate 33 is fixed on the support shaft 2 31, and a gear 32 is also fixed on the support shaft 2 31; a sleeve ring body 27 is also rotatably provided on the adjustment shaft 15, and an L-shaped rod 28 is fixed to the lower side of the sleeve ring body 27, and the L-shaped rod 28 is also slidably connected to the adjustment seat body 4, and a rack 29 meshing with the gear 32 is also fixed on the L-shaped rod 28.

[0039] Preferably, the center of the curved support frame 13 is located on the axis of the support shaft 12, and a curved support frame 13 is provided on each of the front and rear sides of the main support frame 5. The adjustment seat body 4 is located between the two curved support frames 13 to ensure the reliability of supporting the load plate 2. The lower part of the main support frame 5 is provided with a sliding hole 2 18 for the curved support frame 13 to slide through.

[0040] Preferably, a cavity 16 is provided on the inner side of the main support frame 5, and a bevel gear 22, a bevel gear 23, a cam 30, a support shaft 21, a gear 32 and a contact plate 33 are all located in the cavity 16. A sliding hole 17 is provided between the cavity 16 and the sliding hole 218 for the positioning block 35 to slide up and down. The lower end of the positioning block 35 is an arc shape that matches the curved support frame 13, and the lower end of the positioning block 35 can simultaneously abut against the two curved support frames 13; the lower end of the spring 234 is fixed to the bottom of the cavity 16; a cavity 20 is provided on the inner side of the adjustment seat body 4, and a sliding hole 319 for the L-shaped rod 28 to slide is provided between the cavity 16 and the cavity 220. The adjustment seat body 4 is also provided with a sliding hole 4 21 for the sliding and rotation of the adjustment shaft 15.

[0041] Preferably, the elastic force of the spring 1 25 is greater than the elastic force of the spring 2 34; the cross section of the multi-faceted driving rod 26 is a regular polygon, and the sliding and transmission do not affect each other; when there is no external force, such as Figure 4 and 5 As shown, under the elastic force of the spring 1 25 and the spring 2 34, the sleeve ring body 27 abuts against one end of the cavity 20 near the slide hole 4 21, and at this time the lower end of the positioning block 35 abuts against the curved support frame 13. Since the curved support frame 13 cannot move, the support shaft 12 cannot rotate either, thereby achieving simultaneous fixation of the support shaft 12 and the curved support frame 13. When the control knob 14 is pressed, as shown in FIG. Figure 7 As shown, until the end of the L-shaped rod 28 abuts against the side wall of the cavity 16 away from the sliding hole 3 19, during which the rack 29 drives the gear 32, thereby causing the cam 30 to rotate. Under the elastic force of the spring 2 34, the positioning block 35 is released from the fixed state of the curved support frame 13, and the control knob 14 is then rotated. The transmission of the adjustment shaft 15, the multi-faceted drive rod 26 and the drive shaft 24 drives the bevel gear 2 23 to rotate, thereby driving the bevel gear 1 22 to rotate, thereby adjusting the tilt angle of the photovoltaic panel 3. It can be understood that after releasing the control knob 14, it can be restored to its original position by the spring 2 34 and the spring 1 25, ensuring that it is re-locked and fixed after adjustment, and is stable and reliable.

[0042] The above embodiment of the present invention provides a photovoltaic support structure, and its working principle is as follows:

[0043] Initial state (locked state): In the absence of external force, the pressing adjustment assembly, through the action of spring 1 25 and spring 2 34, makes the sleeve ring body 27 abut against the end of the cavity 20 of the adjustment seat body 4 close to the sliding hole 4 21, and at the same time, the lower end of the positioning block 35 is in close contact with the curved support frame 13, fixing the position of the support shaft 12 and the curved support frame 13, ensuring that the load plate 2 and the photovoltaic panel 3 are in a stable state.

[0044] Unlocking and angle adjustment: When the tilt angle of the photovoltaic panel 3 needs to be adjusted, first press the control knob 14. This step will compress the spring 1 25, causing the L-shaped rod 28 to move inward, and drive the gear 32 to rotate through the rack 29, thereby driving the cam 30 to rotate. The rotation of the cam 30 causes the positioning block 35 to move upward under the action of the spring 2 34, releasing the fixation of the curved support frame 13. At this time, since the curved support frame 13 is no longer fixed, the support shaft 12 can rotate freely. The user continues to rotate the control knob 14, and by adjusting the linkage of the shaft 15, the multi-faceted drive rod 26 and the drive shaft 24, the bevel gear 1 22 is finally driven to rotate, thereby changing the angle of the support shaft 12 and adjusting the tilt angle of the photovoltaic panel 3.

[0045] Relocking: After adjusting to the desired angle, release the control knob 14. Under the elastic force of spring 1 25 and spring 2 34, the system automatically returns to the initial locking state, that is, the positioning block 35 contacts and fixes the curved support frame 13 again, the support shaft 12 cannot rotate, and the photovoltaic panel 3 maintains the new tilt angle and remains stable.

[0046] This design not only improves the flexibility of the installation of the photovoltaic panel 3, but also significantly improves the convenience and reliability of angle adjustment, and adapts to the use requirements in different environments.

[0047] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
