[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that, in the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] The main beam has no adjustment margin in the length direction. When there are installation errors in the components at both ends of the main beam, it will make the main beam difficult to install in place.

[0039] Example 1

[0040] In order to solve the above technical problems, Figure 1-4 As shown, this embodiment discloses a tracking bracket for solar cells, wherein the tracking bracket includes a beam assembly and a mounting frame, wherein the mounting frame is arranged at one end of the beam assembly, specifically at the end of the beam assembly close to the south, and the solar cell panel is mounted on the mounting frame.

[0041] The beam assembly serves as the main beam and provides support. It comprises at least two connecting beams 1, a telescopic mechanism 2, and a limiting mechanism. At least two connecting beams 1 are arranged longitudinally, with adjacent connecting beams 1 connected by a telescopic mechanism 2, allowing for adjustable length of the beam assembly. If there are installation errors in the tracking bracket components at either end of the beam assembly, the beam assembly can be quickly reinstalled by adjusting its length.

[0042] Specifically, the beam assembly in this embodiment includes two connecting beams 1, a telescopic mechanism 2, and a limiting mechanism. The two connecting beams 1 are connected by the telescopic mechanism 2. The limiting mechanism is provided at the connection between the two connecting beams 1. The limiting mechanism limits the connecting beams 1 to move only along the length direction, preventing the beam assembly from bending.

[0043] Regarding the number of connecting beams 1, telescopic mechanisms 2 and limiting mechanisms, it should be noted that although in the present embodiment, there are two connecting beams 1 and the corresponding telescopic mechanism 2 and limiting mechanism are both one, this is not a limitation of the present invention. Without departing from the principles of the present invention, in other embodiments, more connecting beams 1 can be selected according to the length of the beam assembly and the connecting beam 1, but as long as adjacent connecting beams 1 are connected by the telescopic mechanism 2 and the connection is covered with a limiting mechanism, this does not deviate from the basic principles of the present invention and will fall within the scope of protection of the present invention.

[0044] Reference Figure 3 and 4The telescopic mechanism 2 includes a scissor mechanism, which includes a first connecting rod assembly and a second connecting rod assembly. The two ends of the first connecting rod assembly are respectively hinged to the two connecting beams 1. The first connecting rod assembly includes a plurality of first connecting rods 211 hingedly connected in sequence; two adjacent first connecting rods 211 are hingedly connected by a connecting pin. The two ends of the second connecting rod assembly are respectively hinged and slidably connected to the two connecting beams 1, and can move radially along the connecting beam 1. The second connecting rod assembly includes a plurality of second connecting rods 212 hingedly connected in sequence, and two adjacent second connecting rods 212 are hingedly connected by a connecting pin. The first connecting rod 211 is hinged to the second connecting rod 212 that crosses it. Specifically, the first connecting rod 211 and the second connecting rod 212 have the same specific size and the same number, and the middle part of the first connecting rod 211 and the second connecting rod 212 that crosses it is hinged by a connecting pin.

[0045] When the scissor mechanism needs to be stretched and extended, the angle between the first connecting rod 211 and the second connecting rod 212 will decrease, and the end of the second connecting rod assembly will move toward the end of the first connecting rod assembly, so that the first connecting rod assembly and the second connecting rod assembly will be lengthened as a whole, thereby stretching and extending the scissor mechanism. When the scissor mechanism needs to be retracted and shortened, the angle between the first connecting rod 211 and the second connecting rod 212 will increase, and the end of the second connecting rod assembly will move away from the end of the first connecting rod assembly, so that the first connecting rod assembly and the second connecting rod assembly will be shortened as a whole, thereby retracting and shortening the scissor mechanism.

[0046] In this embodiment, there are two first connecting rods 211 and two second connecting rods 212 , wherein two ends of the second connecting rod assembly are located on the same side of two ends of the first connecting rod assembly.

[0047] Regarding the number of first connecting rods 211 and second connecting rods 212, it should be noted that while there are two of them in this embodiment, this is not a limitation of the present invention. In other embodiments, the number of first connecting rods 211 and second connecting rods 212 may be three, four, or more, without departing from the principles of the present invention. When there is an odd number of first connecting rods 211 and second connecting rods 212, the two ends of the second connecting rod assembly are located on either side of the first connecting rod assembly. When there is an even number of first connecting rods 211 and second connecting rods 212, the two ends of the second connecting rod assembly are located on the same side of the first connecting rod assembly. Such arrangements do not deviate from the basic principles of the present invention and fall within the scope of protection of the present invention.

[0048] The scissor mechanism further includes two connecting members 23, which are respectively connected to the two connecting beams 1, wherein the connecting members 23 are connected to the main beams by welding, and can also be fixedly connected by bolts or rivets.

[0049] The two ends of the first connecting rod assembly are respectively hinged to the two connecting members 23, and the two ends of the second connecting rod assembly are respectively hinged to the two connecting members 23 and are slidably connected. There are two groups of first connecting rod assemblies and second connecting rod assemblies, with the two groups of first connecting rod assemblies arranged side by side and the two groups of second connecting rod assemblies arranged side by side. Specifically, the connecting member 23 includes a fixed plate and connecting plates arranged on both sides of the fixed plate and integrally formed with the fixed plate; one end of the end connecting plate of the first connecting rod assembly is hinged. A strip hole 231 is provided on the connecting plate along its length, and the end of the second connecting rod assembly is hinged to a connecting pin, which is inserted into the strip hole 231 and can enable the end of the second connecting rod assembly to rotate relative to the connecting plate and slide along the length of the connecting plate. The ends of the two groups of first connecting rod assemblies are respectively hinged to the two connecting plates of the connecting member 23, and the ends of the two groups of second connecting rod assemblies are respectively rotatably and slidably connected to the two connecting plates.

[0050] Regarding the number of first and second connecting rod assemblies, it should be noted that although there are two sets in each embodiment, this is not a limitation of the present invention. Without departing from the principles of the present invention, in other embodiments, those skilled in the art may also choose to have more sets of first and second connecting rod assemblies, with multiple sets of first connecting rod assemblies arranged side by side and multiple sets of second connecting rod assemblies arranged side by side; a first connecting shaft may be provided that passes through the two connecting plates, with the end of the first connecting rod assembly hinged to the first connecting shaft; a second connecting shaft may pass through the strip-shaped holes 231 of the two connecting plates, with the end of the second connecting rod assembly hinged to the second connecting shaft. Such arrangements do not depart from the basic principles of the present invention and fall within the scope of protection of the present invention.

[0051] Preferably, a connecting shaft 24 is provided on the connecting member 23, and the connecting shafts 24 on the two connecting members 23 are staggered, and the two ends of the second telescopic rod 22 are respectively connected to the two connecting shafts 24. The first end of the first connecting rod assembly and the second connecting rod assembly is connected to one of the connecting members 23, and the second end is connected to the other connecting member 23. Specifically, the first end of the first connecting rod assembly is connected to one of the connecting shafts 24, and can be fixedly connected or rotatably connected; the second end is hinged to the connecting plate through a connecting pin. The first end of the second connecting rod assembly is connected to the connecting plate through a connecting pin, and the second end is rotatably or fixedly connected to the other connecting shaft 24. The ends of the first connecting rod and the second connecting rod are both provided with connecting holes, and the connecting shaft 24 and the connecting pin are both passed through the connecting hole.

[0052] The scissor mechanism also includes a second telescopic rod 22, each of which is connected to two connecting shafts 24. The connection can be fixed, but in other embodiments, a rotatable connection is also possible. Because the second telescopic rod 22 is connected to the connecting shafts 24, the second telescopic rod 22 can be arranged at an angle to the connecting beam 1, rather than parallel to the connecting beam 1. Two second telescopic rods 22 are provided, and the two second telescopic rods 22 are arranged side by side.

[0053] Regarding the number of second telescopic rods 22, it should be noted that although there are two in this embodiment, this is not a limitation of the present invention. Without departing from the principles of the present invention, in other embodiments, the number of second telescopic rods 22 may be greater, and multiple second telescopic rods 22 may be arranged side by side. This does not deviate from the basic principles of the present invention and falls within the scope of protection of the present invention.

[0054] The second telescopic rod 22 is provided with an elastic member 221. When the second telescopic rod 22 contracts, the elastic member 221 can drive the second telescopic rod 22 to extend. Specifically, the second telescopic rod 22 includes a sleeve and a piston rod, and the elastic member 221 is specifically a compression spring, which is sleeved on the piston rod. A baffle is provided at the end of the sleeve close to the piston rod, and a baffle is provided at the end of the piston rod away from the sleeve, with the compression spring located between the two baffles. When the second telescopic rod 22 is compressed, the compression spring is also compressed, so that the second telescopic rod 22 can act as a buffer. The second telescopic rod 22 is a hydraulic rod, and the hydraulic pressure of the hydraulic cylinder can also act as a shock absorber and buffer when compressed. Specifically, when the solar panel of the tracking bracket is exposed to wind or impacted by foreign objects, the second telescopic rod 22 can act as a shock absorber and buffer, preventing the tracking bracket from being rigidly displaced.

[0055] The limiting mechanism consists of two clamps 3, which snap onto the ends of the telescopic mechanism 2 and the connecting beam 1. The two clamps 3 are securely connected by bolts. The connecting beam 1 is a square beam, and the clamps 3 are channel-shaped. Connecting edges are provided on the outer edges of the clamps 3, each with a through-hole through which bolts are inserted, allowing the two clamps 3 to connect. The limiting mechanism, which covers the connection, prevents bending of the connecting beam 1 and ensures its support strength.

[0056] Regarding the number of hoops 3, it should be noted that although there are two in this embodiment, this is not a limitation of the present invention. Without deviating from the principles of the present invention, those skilled in the art can choose a larger number of hoops 3, and multiple hoops 3 are arranged around the connecting beam 1, and two adjacent hoops 3 are fixedly connected.

[0057] In order to prevent the limiting assembly from shifting during frequent sliding of the connecting beam 1 , one of the connecting beams 1 is fixedly connected to the limiting assembly, and the other connecting beam 1 can slide relative to the limiting assembly.

[0058] Two hoops 3 are set so that there is a gap between the two hoops 3. The length of the second telescopic rod 22 can be observed through the gap, and the telescopic length of the beam assembly can be determined, and then the error of the components at both ends of the beam assembly can be determined; the position of the components at both ends can be adjusted according to the telescopic length of the beam assembly so that they can be installed in place.

[0059] Example 2

[0060] This embodiment discloses a tracking bracket, the structure of which is substantially the same as that of the tracking bracket in the first embodiment, except for the specific structure of the telescopic mechanism 2 .

[0061] The telescopic mechanism 2 includes a plurality of first telescopic rods arranged side by side. Specifically, the telescopic mechanism 2 also includes a connecting plate fixed to the end of the connecting beam 1, with the ends of the first telescopic rods respectively fixed to the connecting plate. The connecting plate is fixed to the connecting beam 1 by welding, screwing, or riveting. The first telescopic rods are specifically connected to the connecting plate by bolts or welding.

[0062] The plurality of first telescopic rods are evenly arranged along the circumference of the connecting beam 1. Since the connecting beam 1 is a hollow tube structure, the even arrangement along the circumference of the connecting beam 1 can make the connecting beam 1 evenly stressed, and only the side walls of the connecting beam 1 are stressed.

[0063] The first telescopic rod is provided with an elastic member, which can drive the first telescopic rod to extend when the first telescopic rod is retracted. The structure of the first telescopic rod is the same as that of the second telescopic rod 22, and the details will not be repeated here.

[0064] By observing the length of the first telescopic rod through the gap, the telescopic length of the beam assembly can be determined, and then the error of the components at both ends of the beam assembly can be determined; the position of the components at both ends can be adjusted according to the telescopic length of the beam assembly so that they can be installed in place.

[0065] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
