[0029] Please see Figures 1-5 The photovoltaic bracket shown is easy to unfold and includes a fixed frame 1 and side frames 2 arranged on both sides of the fixed frame 1. The side frames 2 are connected to the fixed frame 1 through connecting components 3.

[0030] The connecting assembly 3 includes a telescopic hydraulic rod 301, a fisheye connector 302, a first rotating shaft 303, a second rotating shaft 304, a connecting block 305, and a bearing seat with shaft 306.

[0031] One end of the telescopic hydraulic rod 301 is connected to the support leg 101 of the fixed frame 1 through a double-ear connecting lug, and its telescopic rod is connected to the rotating shaft 303 through a fisheye connector 302. This connection method can not only ensure the stable connection between the telescopic hydraulic rod 301 and the support leg 101, but also use the fisheye connector 302 to adapt to changes in a certain angle, making the telescopic action smoother.

[0032] The rotating shaft 303 is located at one end of the connecting block 305 and can rotate freely in the connecting block 305, which allows the connecting block 305 to flexibly change its angle relative to the telescopic hydraulic rod 301.

[0033] The second rotating shaft 304 is located at the end of the connecting block 305 away from the first rotating shaft 303, and the middle part of the second rotating shaft 304 is connected to the shaft bearing seat 306. The base of the shaft bearing seat 306 is connected to the fixed frame 1. The second rotating shaft 304 can rotate freely in the connecting block 305. The connecting block 305 is rotatably connected to the fixed frame 1 through the second rotating shaft 304. In conjunction with the first rotating shaft 303, it provides multi-degree-of-freedom movement conditions for the unfolding and retraction of the side frame 2.

[0034] The upper end face of the connecting block 305 is connected to the side frame 2, which tightly connects the side frame 2 and the connecting component 3, thereby realizing the transmission of force and the adjustment of angle.

[0035] The mounting bracket 1 includes a support leg 101, a horizontal support rod 102, and a first panel mounting frame 103.

[0036] One set of transverse support rods 102 and two sets of support legs 101 are provided. The two ends of each transverse support rod 102 are fixedly connected to the two ends of the two support legs 101. This structure forms a stable bottom support frame to ensure the load-bearing capacity of the entire bracket.

[0037] The first panel mounting frame 103 is fixedly mounted on the upper surface of the two horizontal support rods 102, providing a mounting base for the photovoltaic panel and ensuring the flatness and stability of the panel installation.

[0038] The side frame 2 includes two symmetrically arranged transverse support rods 201 and a second panel mounting frame 202. The lower end face of each transverse support rod 201 is fixedly connected to the upper end face of the corresponding connecting block 305, so that the side frame 2 can unfold or retract with the movement of the connecting assembly 3.

[0039] The second panel mounting frame 202 is fixedly installed on the upper end face of the second horizontal support rod 201 and is used to install photovoltaic panels, cooperating with the mounting frame on the fixing frame 1.

[0040] The two ends of the first transverse support rod 102 are provided with V-blocks 104, and the end of the second transverse support rod 201 near the V-blocks 104 is provided with a V-groove 203 that matches the V-blocks 104. When the side frame 2 is retracted, the V-blocks 104 and the V-groove 203 cooperate with each other to play the role of positioning and enhancing connection stability.

[0041] Each support leg 101 is also equipped with a lifting lug at its top, and the horizontal height of the top of the lifting lug is lower than the horizontal height of the upper surface of the first panel mounting frame 103. The lifting lug facilitates the hoisting operation of the entire photovoltaic bracket on the installation site, and its height design avoids interference with other components during hoisting.

[0042] The second transverse support rod 201 has a pin hole 4 on its side near the V-groove 203. The pin hole 4 passes through the second transverse support rod 201 and the V-block 104. When the side frame 2 is fully retracted and fits against the fixing frame 1, the pin can be inserted to further fix the position of the side frame 2 and improve the overall stability.

[0043] Working principle:

[0044] When deployment is required, the telescopic hydraulic rod 301 is activated. The telescopic hydraulic rod 301 serves as the main power source for the entire deployment action, its internal hydraulic system pushing the telescopic rod outwards. Since one end of the telescopic rod is connected to the rotating shaft 303 via a fisheye joint 302, which has multi-degree-of-freedom movement, it allows the telescopic rod to smoothly transmit thrust to the rotating shaft 303 even with a certain angular deviation from the connecting block 305 during extension.

[0045] A rotating shaft 303 is located at one end of the connecting block 305 and can rotate freely. Upon receiving thrust from the telescopic hydraulic rod 301, the rotating shaft 303 begins to rotate within the connecting block 305, causing a change in the angle between the connecting block 305 and the telescopic hydraulic rod 301. Simultaneously, the middle of a rotating shaft 304 at the other end of the connecting block 305 is connected to a bearing seat 306, and the rotating shaft 304 can also rotate freely within the connecting block 305. The bearing seat 306 is fixed to the mounting frame 1. This structural design allows the connecting block 305 to rotate and swing relative to the mounting frame 1 around the rotating shaft 304, driven by the rotation of the rotating shaft 303, thus converting the linear telescopic motion of the telescopic hydraulic rod 301 into multi-angle rotation of the connecting block 305.

[0046] The upper surface of the connecting block 305 is fixedly connected to the side frame 2, so when the connecting block 305 rotates and swings as described above, the side frame 2 also moves synchronously. The second transverse support rod 201 included in the side frame 2 is tightly fixed to the connecting block 305. Driven by the connecting block 305, the second transverse support rod 201 gradually moves away from the fixed frame 1, causing the side frame 2 to begin to unfold. As the telescopic hydraulic rod 301 continues to extend, the connecting assembly 3 continuously adjusts its angle, and the side frame 2 continues to unfold until it reaches the preset unfolding angle. This preset angle can be precisely controlled by manually setting the stroke of the telescopic hydraulic rod 301 or by using an angle sensor to monitor the angle between the side frame 2 and the fixed frame 1 in real time, ensuring that the photovoltaic panel can be adjusted to the optimal orientation according to the actual light requirements, maximizing the solar energy reception efficiency. When the side frame 2 is fully extended and the V-block 104 and V-groove 203 are tightly fitted together, the pin hole 4 on the side of the second horizontal support rod 201 is connected to the corresponding hole on the V-block 104. At this time, the pin is inserted to further fix the side frame 2 and the fixing frame 1 firmly, ensuring the integrity and safety of the entire photovoltaic support system.

[0047] When the side frame 2 does not need to be deployed, the retraction program of the telescopic hydraulic rod 301 is initiated. At this time, the internal structure of the hydraulic rod operates in reverse, causing the telescopic rod to retract. Similar to the deployment process, the force of the telescopic rod retraction acts on the rotating shaft 303 through the fisheye joint 302, only the direction of the force is opposite.

[0048] Under the action of the retraction force, the first rotating shaft 303 rotates in the opposite direction, causing the connecting block 305 to rotate and swing in the opposite direction. Due to the presence of the second rotating shaft 304 and the bearing seat 306, the connecting block 305 can smoothly rotate around the second rotating shaft 304 towards the fixed frame 1. During this process, the side frame 2 connected to the upper end face of the connecting block 305 also moves synchronously, and the second transverse support rod 201 gradually approaches the fixed frame 1.

[0049] As the side frame 2 approaches the fixed frame 1, the V-shaped blocks 104 at both ends of the first transverse support rod 102 gradually align and cooperate with the V-shaped groove 203 at one end of the second transverse support rod 201. The V-shaped structure design not only serves as a guide and positioning element, ensuring that the side frame 2 can accurately return to its retracted position relative to the fixed frame 1, but also resists lateral forces to a certain extent, enhancing the overall structural stability in the retracted state. The embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
