Referring to FIGS. 1 to 3, a solar power generation device, specifically, the solar power generation device includes a carrier 1, a solar rack 2 and solar panels 3. The solar rack 2 is disposed on the carrier 1 and is a support and mounting structure for the solar panels 3. The solar panel 3 is provided in the solar rack 2, specifically in the frame 22 hereinafter. The solar rack 2 includes a bracket 21, a frame assembly, and a first power mechanism 23. The bracket 21 is provided on the carrier 1, the frame assembly includes two frames 22, the first frame 22a and the second frame 22b respectively, the inner end of the first frame 22a is pivotally connected to the bracket 21, the second frame 22b is pivotally connected to the outer end of the first frame 22a, the first frame 22a and the second frame 22b are provided with the solar panel 3, the first power mechanism 23 is provided on the bracket 21, the output end of the first power mechanism 23 is connected to the first frame 22 to drive the first frame 22a to be folded or unfolded. In the embodiment of the present application, the carrier 1 is the carrying device of the solar rack 2 and the solar panels 3, the bracket 21 is the support structure of the frame assembly, and the frame assembly is the mounting structure for the solar panels 3. The first power mechanism 23 is mounted on the bracket 21, and the output end of the first power mechanism 23 is connected to the first frame 22a, and the first power mechanism 23 pushes the first frame 22a to swing upward to the vertical state or swing downward to the inclined downward state. In this way, when the first power mechanism 23 pushes the first frame 22a to swing upward, the first frame 22a drives the second frame 22b to be folded and stored, and when the first power mechanism 23 pushes the first frame 22a to swing downward, the first frame 22a drives the second frame 22b to be stretched outward; and when the first frame 22a and the second frame 22b are unfolded, the outer end of the second frame 22b abuts against the external support surface. The support surface is the structure of the power generation device, so it is named by the external support surface, specifically, the support surface can be the ground, of course, it can also be a structure carried or supported by the ground, and the ground is used as an example in the following. In the embodiment of the present application, the first frame 22a can easily and conveniently drive the second frame 22b to move when swinging upwards, so that the first frame 22a and the second frame 22b are folded and gathered on the bracket 21, the carrier 1 can completely carry the frame assembly in the stored state. In this embodiment, the power mechanism of the second frame 22b is omitted, and in the unfolded state, the second frame 22b is affected by gravity, and the outer end of the second frame 22b hangs freely, so that the outer end of the second frame 22b abuts against the support surface when it is unfolded, and the carrier

1 half carries the frame assembly in the unfolded state. Thus, in the unfolded state, the frame assembly is jointly carried by the carrier 1 and the support surface, so that the solar power generation device in the embodiment of the present disclosure may simplify the power mechanism for driving the second frame 22b to be folded and unfolded, and the attachment structure for mounting the power mechanism, thereby simplify the solar power generation device. In addition, when setting the power mechanism and attachment structure driving the second frame 22b, the first frame 22a acts as the mounting structure for the power mechanism of the second frame 22b, requires higher strength to carry the power mechanism output power and higher bearing force to carry the power mechanism and the attachment structure. Therefore, in the embodiment of the present application, the requirements of the strength and bearing force for the first frame 22a is low, which may reduce the strength and bearing force of the first frame 22a, and simplify the structure of the first frame 22a, make the first frame 22a and the bracket 21 more lightweight. For the aforementioned inner end, one end of the frame assembly is connected to the bracket 21 and the other extends outward, the inner end specifically refers to the end near the bracket 21 and the outer end refers to the end away from the bracket 21. In some embodiments of the bracket 21, referring to FIG. 2 and FIG. 3, the bracket 21 includes a chassis 211 and a pivoting frame 212. The chassis 211 is located on the lower part of the bracket 21 and is the base support structure. The pivoting frame 212 is pivotally connected to the chassis 211 and is a mounting structure for the frame assembly. In this embodiment of the present application, during the unfolding of the frame assembly, referring to Fig.5, the second frame 22b is affected by gravity and hangs freely, when the first frame 22a swings down to the position of the second frame 22b grounded or near the ground, the outer end of the second frame 22b can be manually moved so that the outer end of the second frame 22b swings outward, for example, referring to FIG. 7, the second frame 22b is swung outward until the angle between the second frame 22b and the first frame 22a is greater than 90 degrees, so that the outer end of the second frame 22b can automatically move outward when the first power mechanism 23 pushes the first frame 22a to swing downward. Of course, when the first power mechanism 23 pushes the first frame 22a to swing downward, referring to Fig.6, it can also push the pivoting frame 212 to swing downward with the first frame 22a. During the swing of the pivoting frame 212, the pivoting position of the inner end of the first frame 22a is changed, and the position of the second frame 22b is also changed, so as to adjust the position of the second frame 22b grounding or near the ground to avoid the uneven ground. In order to improve the stability of the bracket 21, referring to FIG. 9, at least two chassis 211 are disposed at the bottom of the bracket 21, and each chassis 211 is disposed side by side. For the chassis 211, specifically, referring to FIG. 4 and FIG. 9, the chassis 211 includes a crossbar 2111 and a pivoting lug 2112. The chassis 211 is disposed along a first direction, the first direction can be the length direction or the width direction of the carrier 1, the preferred first direction in the embodiment is the length direction of the carrier 1, then the crossbar 2111 is perpendicular to the first direction.

The inner end of the first frame 22a is pivotally connected to the longitudinal beam 2122. In the structure of driving the pivoting frame 212 to swing downward with the first frame 22a, the upright column 2121 can be used as a manual structure. The pivoting frame 212 further includes a pivoting member 2123. Referring to Fig.9, one end of the pivoting member 2123 is provided with a groove 21231 with a shape suitable for the longitudinal beam 2122, and the pivoting member 2123 is sleeved to the longitudinal beam 2122 via the groove 21231, and the pivoting member 2123 is fixedly connected to the longitudinal beam 2122. The other end of the pivoting member 2123 is provided with a through hole for pivoting, specifically, the pivoting member 2123 is pivotally connected to the first frame 22a. The pivoting member 2123 is adapted to the longitudinal beam 2122 in the form of a groove 21231 to improve the stability of the pivoting member 2123 when connected to the longitudinal beam 2122, for example, when the pivoting member 2123 is welded to the longitudinal beam 2122, the pivoting member 2123 and the longitudinal beam 2122 has a longer weld seam, which has a higher connection stability. In order to improve the convenience of pushing the pivoting frame 212 to swing downward with the first frame 22a, referring to FIG. 2 and FIG. 3, the solar rack 2 also includes a second power mechanism 24, disposed on the chassis 211, and the output end of the second power mechanism 24 is connected to the pivoting frame 212. In this way, the second power mechanism 24 can be used to push the pivoting frame 212 to swing down with the first frame 22a and push the hinge frame 212 to reset when it needs, so as to improve the automatic performance of the folding and extension of the frame assemblies. For the aforementioned first power mechanism 23, it can be specifically a hydraulic push rod or an electric push rod. The second power mechanism 24 is a hydraulic push rod or an electric push rod.

In some embodiments of the solar rack 2, referring to Figures 1 and 2, the solar rack 2 also includes at least two synchronizing shafts 25, one is connected to each first frame 22a on the same side, and another is connected to each second frame 22b on the same side. Specifically, when a plurality of frame assemblies are provided on one side of the pivoting frame 212, the solar rack 2 also includes two synchronizing shafts 25, which are connected to each first frame 22a and each second frame 22b, respectively; when a plurality of frame assemblies are provided on both sides of the pivoting frame 212, the solar rack 2 further includes four synchronizing shafts 25, which are arranged two by two on both sides of the solar rack 2. Further, the solar rack 2 also includes a locking mechanism disposed on the bracket 21. When the frame assembly is in a folded state, the locking mechanism is also connected to the frame assembly to lock the frame assembly. When the frame assembly is in the folded state, as the carrier 1 moves, the frame assembly is impacted by vibration or agitation, and it's possibly causing the frame assembly stretching, which is unfavorable for the carrier 1 to transport the solar rack 2 and the solar panels 3.

For the locking mechanism, in one of the embodiments, referring to Fig.4, the locking mechanism is a rotatable hook device 26, the hook device 26 includes a motor mounted at the upper end of the bracket 21, a reducer connected to the motor, and a hook connected to the motor, the hook includes a handle and a hook portion, the handle is connected to the reducer, and the hook portion is provided at the end of the handle. Usually, the hook portion is downward due to the influence of gravity or other mechanism, and rotating the handle by the motor makes the hook portion rotate upward or downward. Before the frame assembly completes folding, the hook portion rotates upward to avoid the frame assembly; upon full folding of the frame assembly, the hook portion is rotated downward, and the hook engages with the frame assembly, thus locking the frame assembly and preventing accidental extension of the frame assembly. When the frame assembly is unfolded, the hook portion is rotated upward to avoid the frame assembly, and when the first frame 22a swings downward and away from the hook device 26, the hook device 26 is reset.

The roller can also be disposed at other positions of the bracket 21, such as the lower end of the upright column 2121, when the upper end of the upright column 2121 is provided with a fixed pulley, the traction rope is led to the upright column 2121 by arranging a fixed pulley on the column 2121. For the specific locking position of the locking mechanism, specifically, the first frame 22a, the second frame 22b or the synchronizing shaft 25 can be locked. At least one side of the pivoting frame 212 is provided with a plurality of frame assemblies disposed in a straight line. In this way, the locking mechanism preferably locks the synchronizing shaft 25 set at the outer end connecting lug 222 of the first frame 22a.
