The photovoltaic panel frame 1 is used to install photovoltaic solar panels.

[0040] Through the angle adjustment structure, the photovoltaic panel frame 1 can be flipped relative to the bottom frame. The photovoltaic panel frame 1 is accommodated in the bottom frame in a folded state, which reduces the space occupied after folding, and is convenient for stacking and transportation of multiple groups. The photovoltaic panel frame 1 can be unfolded to any angle under the support of the angle adjustment structure in the unfolded state. The angle adjustment is convenient, which can improve the layout efficiency when deployed over a large area. The foldable photovoltaic bracket can be retracted after installation, and different regions can adjust to the optimal power generation angle according to different irradiation angles throughout the year. In addition, the foldable photovoltaic bracket can be folded quickly, which is convenient for users to move and transport the entire photovoltaic system for outdoor life such as camping, hiking, self-driving, and emergency preparedness, outdoor rescue and other scenes; when encountering severe weather such as rain and snow, the entire photovoltaic system can be folded and placed in a safer space to avoid the photovoltaic system from being subjected to large wind loads or snow loads.

[0041] The bottom frame of the foldable photovoltaic bracket includes a first supporting cross bar 21, a second supporting cross bar 22 and a connecting piece 23.

[0042] Specifically, the connecting member 23 includes a first cross bar 231 and a second cross bar 232; the first cross bar 231 and the second cross bar 232 are parallel to each other; one end of the first cross bar 231 is detachably connected to the middle part of the first supporting cross bar 21, and the other end of the first cross bar 231 is detachably connected to the middle part of the second supporting cross bar 22; one end of the second cross bar 232 is detachably connected to the middle part of the first supporting cross bar 21, and the other end of the second cross bar 232 is detachably connected to the middle part of the second supporting cross bar 22.

[0043] In a specific embodiment of the present invention, the first support cross bar 21 and the second support cross bar 22 are connected by the first cross bar 231 and the second cross bar 232. The use of the first cross bar 231 and the second cross bar 232 to connect the first support cross bar 21 and the second support cross bar 22 can enhance the stability of the bottom frame and reduce the deformation of the bottom frame caused by the connecting member 23 being squeezed by external force.

[0049] The angle adjustment rod 3 is extended by the telescopic rod 32 to change the overall length of the angle adjustment rod 3, thereby achieving the effect of adjusting the photovoltaic panel frame 1 to a predetermined angle relative to the bottom frame.

[0050] The elastic plug 33 is a length adjustment mechanism for the angle adjustment rod 3; positioning holes 320 are opened on both sides of the telescopic rod 32, and the telescopic part of the elastic plug 33 is usually in a protruding state. When the telescopic rod 32 slides to the positioning hole 320, the telescopic part of the elastic plug 33 enters the positioning hole 320 under the elastic force of the spring, thereby realizing structural positioning. With the above structure, the method of adjusting the angle adjustment rod 3 is simple. It only needs to move the telescopic part of the elastic plug 33 away from the positioning hole 320 to make the telescopic rod 32 slide relative to the sleeve rod 31, which is convenient for folding or installing the foldable photovoltaic bracket.

[0051] The elastic pin 33 is connected to the fixing seat 311 by threads, which is convenient for replacement when there is a problem with the structure. It is suitable for outdoor products such as photovoltaics that are designed to have a long service life.

[0054] Specifically, the elastic latch 33 includes a reset spring latch, and the reset spring latch includes a reset bolt portion 331, a reset sliding portion 332, a reset latch portion 333 and a reset grip portion 334;

[0055] The reset bolt part 331 and the reset sliding part 332 are integrally formed, and a first sliding channel runs through the reset bolt part 331 and the reset sliding part 332; an external thread is provided on the outer side of the reset bolt part 331, and the reset bolt part 331 is threadedly connected to the connecting tube 312;

[0056] The reset latch portion 333 and the reset grip portion 334 are integrally formed, and the reset latch portion 333 is inserted into the first sliding channel. A first spring 335 is provided in the first sliding channel. The first spring 335 is sleeved on the outer side of the reset latch portion 333. One end of the first spring 335 is fixed to the inside of the first sliding channel. A first fixing ring 3331 protrudes outward from the middle of the reset latch portion 333, and the other end of the first spring 335 is tightly against the first fixing ring 3331.

[0057] In a specific embodiment of the present invention, the elastic latch 33 includes a reset spring latch, and the first spring 335 extends the reset latch portion 333 out of the first sliding channel through the first fixing ring 3331, so that the reset latch portion 333 is always kept in a state of protruding from the reset bolt portion 331. The reset latch portion 333 passes through the first through hole and the second through hole in sequence, and enters the positioning hole 320, so as to realize the structural positioning of the sleeve rod 31 and the telescopic rod 32.

[0058] The reset grip portion 334 serves as a limit to prevent the reset latch portion 333 from excessively extending out of the first sliding channel; at the same time, the reset grip portion 334 serves to provide a grip; during installation or folding, the staff can pull the reset latch portion 333 outward through the reset grip portion 334 to retract the reset latch portion 333 into the first sliding channel, thereby allowing the telescopic rod 32 to slide in the sleeve rod 31; when the corresponding positioning hole 320 is selected, the reset grip portion 334 is released, the first spring 335 is reset, and the first spring 335 causes the reset latch portion 333 to extend out of the first sliding channel again through the first fixing ring 3331, thereby being inserted into the positioning hole 320 again.

[0059] Specifically, the elastic latch 33 includes a self-locking spring latch, and the self-locking spring latch includes a self-locking bolt portion 336, a self-locking sliding portion 337, a self-locking latch portion 338 and a self-locking grip portion 339;

[0060] The self-locking bolt portion 336 and the self-locking sliding portion 337 are integrally formed, and a first sliding channel runs through the self-locking bolt portion 336 and the self-locking sliding portion 337; an external thread is provided on the outer side of the self-locking bolt portion 336, and the self-locking bolt portion 336 is threadedly connected to the connecting tube 312;

[0061] The self-locking latch portion 338 and the self-locking grip portion 339 are integrally formed, and the self-locking latch portion 338 is inserted into the first sliding channel.

One end of the second spring 330 is fixed inside the first sliding channel. A second fixing ring 3381 protrudes outward from the middle of the self-locking latch portion 338, and the other end of the second spring 330 is tightly against the second fixing ring 3381.

[0062] The self-locking gripping portion 339 is provided with a self-locking protrusion 3391 on the side facing the self-locking pin portion 338 , and the self-locking sliding portion 337 is provided with an avoidance cavity 301 that matches the shape of the self-locking protrusion 3391 on the side facing away from the sleeve rod 31 ; the self-locking protrusion 3391 is embedded in the avoidance cavity 301 .

[0063] In a specific embodiment of the utility model, the elastic latch 33 includes a self-locking spring latch, and the principle of the self-locking spring latch locking the telescopic rod 32 is the same as that of the reset spring latch. The second spring 330 extends the self-locking latch portion 338 out of the second sliding channel through the second fixing ring 3381, so that the self-locking latch portion 338 always remains in a state of protruding from the self-locking bolt portion 336. The self-locking latch portion 338 passes through the first through hole and the second through hole in sequence, and enters the positioning hole 320, so as to realize the structural positioning of the sleeve rod 31 and the telescopic rod 32. Similarly, when installing or folding, the staff can pull the self-locking pin portion 338 outward through the self-locking grip portion 339, so that the self-locking pin portion 338 retracts into the second sliding channel, thereby allowing the telescopic rod 32 to slide in the sleeve rod 31; when it is determined that the corresponding positioning hole 320 is selected, the self-locking grip portion 339 is released, the second spring 330 is reset, and the second spring 330 allows the self-locking pin portion 338 to extend out from the second sliding channel again through the second fixing ring 3381, so that it is inserted into the positioning hole 320 again.

[0064] In addition, since the self-locking grip 339 is provided with a self-locking protrusion 3391 on the side facing the self-locking latch 338, the self-locking grip 339 is rotated 90 degrees while being pulled out, so that the self-locking protrusion 3391 and the avoidance cavity 301 are misaligned, so that the self-locking latch 338 is kept in the second sliding channel, which is convenient for the staff to slide the telescopic rod 32 to adjust the angle. After selecting the corresponding positioning hole 320, the self-locking grip 339 is rotated 90 degrees in the opposite direction while being pulled out, and the self-locking protrusion 3391 can be embedded in the avoidance cavity 301, so that the second spring 330 is reset, and the second spring 330 makes the self-locking latch 338 extend out of the second sliding channel again through the second fixing ring 3381, so as to be inserted into the positioning hole 320 again.

[0065] In a specific embodiment of the present invention, first through holes are provided on both sides of the top proximal end of the sleeve rod 31; a self-locking spring latch is provided on one side of the sleeve rod 31, and a reset spring latch is provided on the other side.
