[0002] Traditional photovoltaic support structures are usually inconvenient to install and adjust, especially when adjusting the tilt angle of photovoltaic panels, which often requires complex tools and long operation time. This inconvenience not only increases the cost of installation and maintenance, but also limits the flexibility and adaptability of photovoltaic systems, especially when facing different terrains and lighting conditions.

[0003] In order to solve these problems, various improved photovoltaic bracket designs have emerged in the market.

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

[0022] In the 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 stably support 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 + rotate 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.

[0023] like Figure 1-3 As shown, as a preferred embodiment of the present invention, the lower sides of both ends of the support frame 6 are fixed with reverse U-shaped card plates 7, which can be positioned on the fixed frame 1 in cooperation with the card plates, and the two sides of the reverse U-shaped card plates 7 are also installed with fastening bolts 8 for locking and fixing the reverse U-shaped card plates 7 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.

[0025] like Figure 3-7 As shown, as a preferred embodiment of the present invention, the press adjustment assembly includes a bevel gear 22 installed and fixed on the support shaft 12, a driving shaft 24 is rotatably provided on the inner side of the adjustment seat body 4, one end of the driving shaft 24 is fixed with a bevel gear 23 meshing with the bevel gear 22, and the other end of the driving shaft 24 is slidably provided with a polygonal driving rod 26, an adjustment shaft 15 is fixed to the end of the polygonal driving rod 26 away from the driving shaft 24, the adjustment shaft 15 is slidably and rotatably connected with the adjustment seat body 4, and a control knob 14 is fixed to the end of the adjustment shaft 15 away from the polygonal driving rod 26, and a spring 25 is also sleeved on the polygonal driving rod 26; the inner lower side of the main support frame 5 A positioning block 35 is slidably provided on the main support frame 5 for abutting and fixing the curved support frame 13, a contact plate 33 is fixed on the upper end of the positioning block 35, and a spring 2 34 is provided on the lower side of the contact plate 33 for elastically supporting it, a support shaft 2 31 is rotatably provided in the main support frame 5 between the support shaft 12 and the contact plate 33, a cam 30 abutting and cooperating 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 rod 15, an L-shaped rod 28 is fixed on the lower side of the sleeve ring body 27, the L-shaped rod 28 is also slidably connected to the adjustment seat body 4, and a rack 29 meshingly connected to the gear 32 is also fixed on the L-shaped rod 28.

[0026] Preferably, the center of the curved support frame 13 is located on the axis of the support shaft 12, a curved support frame 13 is provided on each of the front and rear sides of the main support frame 5, and the adjustment seat body 4 is located between the two curved support frames 13 to ensure the reliability of supporting the load plate 2, and a sliding hole 18 is provided at the lower part of the main support frame 5 for the curved support frame 13 to slide through.

[0027] 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, and 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, and 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 3 19 for the L-shaped rod 28 to slide is provided between the cavity 16 and the cavity 20, and a sliding hole 4 21 is also provided on the adjustment seat body 4 for adjusting the sliding and rotation of the shaft rod 15.

[0028] 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 close to the sliding hole 4 21, and at this time, the lower end of the positioning block 35 abuts against the curved support frame 13. Because 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 a side wall of the cavity 16 away from the sliding hole 3 19, during which the rack 29 drives the gear 32, so that the cam 30 rotates, and under the elastic force of the spring 2 34, the positioning block 35 releases the fixed state of the curved support frame 13, and then the control knob 14 is rotated, and the transmission of the adjustment shaft 15, the multi-faceted driving rod 26 and the driving shaft 24 drives the bevel gear 2 23 to rotate, thereby driving the bevel gear 1 22 to rotate, and adjusting the inclination angle of the photovoltaic panel 3. It can be understood that after releasing the control knob 14, the spring 2 34 and the spring 1 25 can be used to restore the original position, ensuring that the adjustment is re-locked and fixed, which is stable and reliable.

[0029] The above embodiment of the present invention provides a photovoltaic support structure, and the working principle is as follows: Initial state (locked state): In the absence of external force, the adjustment assembly is pressed through the action of spring 1 25 and spring 2 34, so that the sleeve ring body 27 abuts against one 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.

[0030] 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, thereby 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 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.

[0031] Re-locking: 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.

[0032] 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.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0034] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
