[0040] As Figures 1 to 3As shown, this embodiment discloses a photovoltaic tracking device with a transmission component 5, comprising:

[0041] Bracket 1;

[0042] The powertrain 3 includes a fixed member 31 and a movable member 32. The fixed member 31 is connected to the bracket 1, and the movable member 32 is rotatable about its axis relative to the fixed member 31.

[0043] Photovoltaic panel 2 is connected to the movable component 32;

[0044] Energy storage structure 4 is connected to bracket 1. The energy storage structure 4 includes an energy storage element and an output shaft 41. The energy storage element is connected to the output shaft 41. The output shaft 41 and the movable element 32 form a transmission connection.

[0045] The transmission component 5 is disposed on the bracket 1, and at least one end of the output shaft 41 is connected to the movable component 32 through the transmission component 5.

[0046] It should be noted that in this embodiment, the energy storage component refers to a component that can undergo elastic deformation under external force and has a tendency to recover its original shape before being subjected to external force. When the energy storage component recovers its original shape, it can apply force to external components. That is, the energy storage component is used to overcome the force exerted by the photovoltaic panel 2 on the moving part 32 of the power assembly 3, and under the action of the output shaft 41, it assists the power assembly 3 in driving the photovoltaic panel 2 to rotate. Based on satisfying the function of the energy storage component, the energy storage component can be a planar spiral spring, coil spring, torsion spring, tension spring, etc., or a component of other shapes made of elastic rubber or other materials that can meet the requirements of the booster proposed in this application, or a combination of coil spring, torsion spring, tension spring, or other elastic components.

[0047] Furthermore, in this embodiment, the output shaft 41 adopts a dual-output shaft design, that is, both ends of the output shaft 41 can respectively form a transmission connection with both ends of the movable part 32.

[0048] like Figures 1 to 3 As shown, it should be noted that in this embodiment, the transmission component 5 is used to realize the transmission connection between the movable component 32 and the output shaft 41. The transmission component 5 includes a first transmission part 51 and a second transmission part 52. The first transmission part 51 is used to be transmitted to the movable component 32, and the second transmission part 52 is used to be transmitted to the output shaft 41.

[0049] Furthermore, in this embodiment, the first transmission part 51 and the second transmission part 52 can be directly connected, or be integrally molded, or they can be connected by a connecting rod 53.

[0050] Furthermore, in this embodiment, to achieve the transmission connection between the first transmission part 51 and the movable member 32, the following methods can be adopted, including but not limited to:

[0051] In the first embodiment, the first transmission part 51 is a first gear, and the movable part 32 is provided with a second gear 321 that cooperates with the first gear.

[0052] In the second embodiment, the first transmission part 51 is a first pulley, and the movable part 32 has a second pulley. The first pulley and the second pulley are connected by a belt.

[0053] In the third embodiment, the first transmission part 51 is a first sprocket, the movable part 32 is a second sprocket, and the first sprocket and the second sprocket are connected by a chain.

[0054] Similarly, in this embodiment, the second transmission unit 52 and the output shaft 41 are connected by transmission in several ways, including but not limited to the following:

[0055] In the first embodiment, the second transmission part 52 is a third gear, and the output shaft 41 is provided with a fourth gear 411 that cooperates with the third gear.

[0056] In the second embodiment, the first transmission part 51 is a third pulley, and the movable part 32 has a fourth pulley. The third pulley and the fourth pulley are connected by a belt.

[0057] In the third embodiment, the first transmission part 51 is a third sprocket, the movable part 32 is a fourth sprocket, and the third sprocket and the fourth sprocket are connected by a chain.

[0058] It should be noted that the connection method between the first transmission part 51 and the second transmission part 52 as described above can be arbitrarily combined with the connection method between the second transmission part 52 and the output shaft 41.

[0059] like Figures 1 to 3 As shown, it should be noted that in this embodiment, in order to use an energy storage component with a lower elastic coefficient without affecting the function of the energy storage structure 4, the transmission ratio between the output shaft 41 and the movable component 32 can be adjusted. The transmission ratio can be adjusted by changing the tooth tip circle diameter of the gear and the diameter of the pulley and sprocket.

[0060] For example, when the first transmission part 51 is the first gear and the second transmission part 52 is the third gear; that is, the first transmission part 51 is the first gear, and the movable part 32 is provided with a second gear 321 that cooperates with the first gear, and the first gear meshes with the second gear 321; the second transmission part 52 is the third gear, and the output shaft 41 is provided with a fourth gear 411 that cooperates with the third gear, and the third gear meshes with the fourth gear 411.

[0061] Adjusting the transmission ratio between the moving part 32 and the output shaft 41 can be achieved in at least one of the following ways:

[0062] In the first embodiment, the tip circle diameter of the first gear is greater than the tip circle diameter of the second gear 321.

[0063] In the second embodiment, the tip circle diameter of the third gear is greater than the tip circle diameter of the fourth gear 411.

[0064] In the third method, the tip circle diameter of the first gear is larger than the tip circle diameter of the fourth gear 411.

[0065] It should be noted that, such as Figures 1 to 3 As shown, in this embodiment, one end of the output shaft 41 can be connected to the movable part 32 via the transmission member 5 as described above, or the number of transmission members 5 can be set to two sets, with the two ends of the output shaft 41 respectively connected to the movable part 32 via two sets of transmission members 5.

[0066] It should be noted that in this embodiment, under the action of the two sets of transmission components 5, the two ends of the movable component 32 are respectively connected to the two ends of the output shaft 41, making the force on the two ends of the output shaft 41 more even and the transmission connection between the powertrain 3 and the energy storage structure 4 more stable. The advantages of this embodiment are: it improves the reliability and stability of the transmission connection between the powertrain 3 and the energy storage structure 4, allows the energy storage structure 4 to better assist the powertrain 3 in driving the photovoltaic panel 2 to rotate, and increases the service life of the photovoltaic tracking device.

[0067] First, in this embodiment, the use of transmission component 5 allows the points on the powertrain 3 that form a transmission connection with the two ends of the output shaft 41 in the energy storage structure 4 to be freely set. This makes it easier to set the position on the powertrain 3 for external transmission connection without changing the existing length of the energy storage structure 4 or the existing length of the powertrain 3. This reduces costs and also enables a two-point transmission between the energy storage structure 4 and the powertrain 3, avoiding the possibility of uneven force distribution during single-point transmission. This makes the transmission more stable and ensures the service life of the photovoltaic tracking device.

[0068] Secondly, the first transmission part 51 is a first gear, the movable part 32 is provided with a second gear 321 matched with the first gear, so that the first transmission part 51 and the movable part 32 form a gear transmission; the second transmission part 52 is a third gear, the output shaft 41 is provided with a fourth gear 411 matched with the third gear, so that the second transmission part 52 and the output shaft 41 form a gear transmission; the gear transmission has high reliability, improves the reliability of the transmission part 5, and prolongs the service life.

[0069] Thirdly, the transmission ratio between the movable part 32 and the output shaft 41 is further adjusted by adjusting the addendum circle diameter of the first gear, the second gear 321, the third gear or the fourth gear 411, and the elastic coefficient of the energy storage part is lower by adjusting the speed ratio, and the auxiliary effect of the energy storage structure 4 is not affected when the photovoltaic panel 2, that is, the load weight, is unchanged.
