The disadvantage of this design is that they are large in size and inconvenient to carry and store. Since they cannot be folded, when these brackets need to be transported or stored, they will take up more space, causing inconvenience to users. Utility Model Content

[0006] Preferably, a raising mechanism is provided on the surface of the base frame, and the raising mechanism includes a rotating shaft, the rotating shaft is rotatably connected to the surface of the base frame, a pad rod is fixedly connected to the surface of the rotating shaft, a guide block is fixedly connected to the surface of the guide block, a spring is fixedly connected to the surface of the spring, a positioning rod is fixedly connected to the surface of the spring, and the positioning rod is slidably connected to the surface of the guide block.

[0007] Preferably, the base frame and the support frame are both in a "U" shape, and the photovoltaic panel body is rotated on the surface of the base frame through the support frame, and the inclination angle of the photovoltaic panel body changes during the rotation.

[0008] Preferably, the horizontal height of the rotation point of the support frame is greater than the horizontal height of the rotation point of the adjustment rod on the nut.

[0009] Preferably, the nut slides on the surface of the base frame through the rotation of the screw rod, and the nut drives the support frame to rotate on the base frame through the adjustment rod during the sliding process.

[0010] Preferably, the pad rods rotate on the base frame via a rotating shaft, and four groups of the pad rods are provided.

[0011] Preferably, two groups of positioning grooves are formed on the surface of the pad rod, and the positioning rod is snap-connected to one group of positioning grooves of the pad rod, and the positioning rod limits the rotation angle of the pad rod on the base frame.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A photovoltaic bracket that is easy to fold and store: comprises a base frame 1, a support frame 11 is rotatably connected to the surface of the base frame 1, a photovoltaic panel body 12 is fixedly installed on the surface of the support frame 11, a motor 2 is fixedly connected to the surface of the base frame 1, a screw rod 21 is fixedly connected to the output shaft of the motor 2, the motor 2 drives the screw rod 21 to rotate via the output shaft, a nut 22 is threadedly connected to the surface of the screw rod 21, an adjusting rod 23 is rotatably connected to the surface of the nut 22, an end of the adjusting rod 23 away from the nut 22 is rotatably connected to the support frame 11, the photovoltaic bracket is folded by a folding mechanism, thereby reducing the volume of the photovoltaic bracket, and facilitating carrying and storage of the photovoltaic bracket.

[0024] Furthermore, a raising mechanism is provided on the surface of the base frame 1, and the raising mechanism includes a rotating shaft 3, which is rotatably connected to the surface of the base frame 1, a pad rod 31 is fixedly connected to the surface of the rotating shaft 3, a guide block 32 is fixedly connected to the surface of the base frame 1, a spring 33 is fixedly connected to the surface of the guide block 32, a positioning rod 34 is fixedly connected to the surface of the spring 33, and the positioning rod 34 is slidably connected to the surface of the guide block 32. The raising mechanism can increase the height of the photovoltaic bracket, and then increase the height of the photovoltaic panel body 12, so that the photovoltaic panel body 12 can better absorb solar energy and avoid the photovoltaic panel body 12 being too low and blocked.

[0025] Furthermore, the base frame 1 and the support frame 11 are both in a "U" shape, and the photovoltaic panel body 12 is rotated on the surface of the base frame 1 through the support frame 11. The inclination angle of the photovoltaic panel body 12 changes during the rotation, and the angle of the photovoltaic panel body 12 can be adjusted, thereby improving the flexibility of the photovoltaic bracket. In addition, the support frame 11 can be rotated to make the photovoltaic bracket as a whole in a folded state.

[0026] Furthermore, the horizontal height of the rotation point of the support frame 11 is greater than the horizontal height of the rotation point of the adjusting rod 23 on the nut 22. After the support frame 11 and the adjusting rod 23 are rotated, they will be parallel to the base frame 1, and the horizontal height of the support frame 11 will be higher than the adjusting rod 23, avoiding conflict between the support frame 11 and the adjusting rod 23 after rotation.

[0027] Furthermore, the nut 22 slides on the surface of the base frame 1 through the rotation of the screw rod 21. During the sliding process, the nut 22 drives the support frame 11 to rotate on the base frame 1 through the adjusting rod 23, and the adjusting rod 23 is at one end of the nut 22. During the rotation process, the adjusting rod 23 will continuously move its position. The adjusting rod 23 always rotates on the support frame 11, and the bottom of the adjusting rod 23 adapts to the change in the rotation angle of the support frame 11 on the base frame 1 by moving.

[0028] Furthermore, the pad rods 31 rotate on the base frame 1 through the rotating shaft 3. Four groups of pad rods 31 are provided. The four groups of pad rods 31 are folded on the sides of the base frame 1. After the pad rods 31 rotate, they can support the base frame 1, thereby changing the overall height of the entire photovoltaic bracket.

[0029] Furthermore, two groups of positioning grooves are provided on the surface of the pad rod 31, and the positioning grooves on both sides of the pad rod 31 can make the pad rod 31 parallel to the base frame 1, or the pad rod 31 perpendicular to the base frame 1, and the positioning rod 34 is snap-fitted and connected to a group of positioning grooves of the pad rod 31. The positioning rod 34 limits the rotation angle of the pad rod 31 on the base frame 1, and the elastic force of the spring 33 operates on the positioning rod 34, so that the positioning rod 34 is firmly snapped on the positioning hole of the rotating shaft 3.

[0030] Working principle: the output shaft of the motor 2 drives the screw rod 21 to rotate, and the screw rod 21 drives the nut 22 to move on the base frame 1 during the rotation. The nut 22 drives the support frame 11 to rotate on the base frame 1 through the adjusting rod 23 during the movement, and the bottom of the adjusting rod 23 rotates on the nut 22, and the top rotates on the support frame 11 to adapt to the change of the rotation angle of the support frame 11. The support frame 11 and the adjusting rod 23 will rotate to fold on the surface of the base frame 1, thereby realizing the folding of the photovoltaic bracket, reducing the volume of the photovoltaic bracket, and making it convenient for the photovoltaic bracket to be carried in a storage box.

[0031] Pull the positioning rod 34 on the guide block 32 to make the positioning rod 34 disengage from the positioning groove of the pad rod 31. At this time, the spring 33 is pulled to deform, and the four groups of pad rods 31 are rotated ninety degrees on the base frame 1. Then the elastic force of the spring 33 is used to make the positioning rod 34 engage and connect to the positioning groove of the pad rod 31. At this time, the four groups of pad rods 31 are perpendicular to the base frame 1, and the pad rods 31 support the base frame 1, thereby raising the height of the photovoltaic bracket.
