DETAILED DESCRIPTION

[0030] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1 and 3 This embodiment provides a control box, including: a box body 3; multiple first conductive components 1 connected to the box body 3; a central processing controller 41, a power module 42, a battery 43, an input / output module 44, an angle sensor 45 and a wireless module 46, all of which are detachably connected to the multiple first conductive components 1; wherein the input / output module 44, the angle sensor 45 and the wireless module 46 are all communicatively connected to the central processing controller 41.

[0033] Specifically, the box body 3 is used to protect multiple first conductive components 1, a central processing controller 41, a power module 42, a battery 43, an input / output module 44, an angle sensor 45, and a wireless module 46; the number of the first conductive components 1 is not limited, and is preferably three, and the three first conductive components 1 serve as a positive line, a negative line, and a ground line, respectively, so that the battery 43 and the power module 42 can supply power to the central processing controller 41, the input / output module 44, the angle sensor 45, and the wireless module 46 through the three first conductive components 1. The number of the first conductive components 1 can also be six, of which three first conductive components 1 are used for power supply (i.e., as a positive line, a negative line, and a ground line, respectively), and the other three first conductive components 1 are used for signal communication between various components. The number of the first conductive components 1 can also be further expanded and is not limited; the central processing controller 41 is used as the control center of the control box; the power module 42 is used to prevent abnormal conditions such as overvoltage and overcurrent from causing damage to related components. The power module 42 can be powered by the battery 43 of this application, or it can be powered by an external power supply component through the AC / DC interface. Electricity; the battery 43 is used to power the central processing controller 41, power module 42, input / output module 44, angle sensor 45 and wireless module 46 of the present application. The battery 43 can be a lithium battery, a storage battery, etc., preferably a lithium battery; the input / output module 44 is used to connect the angle sensor 45, the wireless module 46 and the drive motor, etc.; the angle sensor 45 is used to detect the rotation angle of the corresponding drive motor, thereby detecting the rotation angle of the corresponding flat single-axis photovoltaic tracking bracket. The specific number of angle sensors 45 can be multiple, as long as the number of angle sensors 45 and the number of drive motors are equal; the wireless module 46 is used to realize wireless communication between different control boxes, or for realizing wireless communication between the control box and the upper control software. The wireless module 46 is preferably a Wi-Fi module; since the central processing controller 41, power module 42, battery 43, input / output module 44, angle sensor 45 and wireless module 46 are all detachably connected to multiple first conductive components 1, it is convenient to disassemble, replace or add relevant functional components as needed without replacing the entire control box, which makes the use cost of the control box low.

[0034] Further, such as Figure 3The central processing controller 41, the power module 42, the battery 43, the input / output module 44, the angle sensor 45, and the wireless module 46 are all connected to a plurality of second conductive components 2, and the plurality of second conductive components 2 are detachably connected to the plurality of first conductive components 1. Specifically, the plurality of second conductive components 2 and the plurality of first conductive components 1 are detachably connected to each other, so that the battery 43 and the power module 42 can supply power to the central processing controller 41, the input / output module 44, the angle sensor 45, and the wireless module 46 through the plurality of second conductive components 2 and the plurality of first conductive components 1. The specific method of the detachable connection is that under the action of gravity, the plurality of second conductive components 2 and the plurality of first conductive components 1 are correspondingly plugged in.

[0035] Further, such as Figure 3 The second conductive component 2 includes: a shell 21 that is detachably mechanically connected to the first conductive component 1; a second conductor 22, one end of the second conductor 22 is mechanically connected to the shell 21, and the other end of the second conductor 22 is electrically connected to the first conductive component 1; wherein, the shell 21 is mechanically connected to the central processing controller 41, the power module 42, the battery 43, the input and output module 44, the angle sensor 45 or the wireless module 46, and one end of the second conductor 22 is electrically connected to the central processing controller 41, the power module 42, the battery 43, the input and output module 44, the angle sensor 45 or the wireless module 46.

[0036] Specifically, the housing 21 serves as a part of the shell of the central processing controller 41, the power module 42, the battery 43, the input / output module 44, the angle sensor 45 or the wireless module 46, which is equivalent to the central processing controller 41, the power module 42, the battery 43, the input / output module 44, the angle sensor 45 or the wireless module 46 each having a separate shell; the second conductor 22 is used to realize the electrical connection between the first conductive component 1 and the central processing controller 41, the power module 42, the battery 43, the input / output module 44, the angle sensor 45 or the wireless module 46. The material of the second conductor 22 can be copper, aluminum, etc., preferably copper.

[0037] Further, such as Figure 3 The second conductive component 2 further includes an elastic member 23, one end of which is connected to the housing 21, and the other end of the elastic member 23 is connected to the other end of the second conductor 22. Specifically, when the other end of the second conductor 22 is electrically connected to the first conductive component 1, the elastic member 23 is compressed. The elastic member 23 is used to resist the compressive force and squeeze the other end of the second conductor 22, so that the other end of the second conductor 22 is in close contact with the first conductive component 1 to prevent poor contact. The elastic member 23 can be made of rubber, spring steel, etc. To ensure insulation performance, the elastic member 23 is preferably made of rubber.

[0038] Further, such as Figure 3 The second conductive component 2 further includes a receiving cavity 24 and a stepped cavity 25, both disposed within the housing 21. The receiving cavity 24 and the stepped cavity 25 are in communication, and the second conductor 22 and the elastic member 23 are both located within the receiving cavity 24. The first conductive component 1 and the receiving cavity 24 and the stepped cavity 25 are all detachably connected. Specifically, the receiving cavity 24 is used to accommodate the second conductor 22 and the elastic member 23; the stepped cavity 25 is configured to be detachably connected to the first conductive component 1, facilitating mutual restraint between the first and second conductive components 1, 2, thereby ensuring good relative stability between the first and second conductive components 1, 2.

[0039] Further, such as Figure 3-4 The first conductive component 1 includes a first conductor 11 and a base 12 that are connected to each other. The base 12 is connected to the housing 3. The base 12 is detachably mechanically connected to the second conductive component 2, and the first conductor 11 is electrically connected to the second conductive component 2. Specifically, the first conductor 11 is used to electrically connect to the second conductor 22 of the second conductive component 2, thereby facilitating the electrical connection between the first conductive component 1 and the central processing controller 41, the power module 42, the battery 43, the input / output module 44, the angle sensor 45, or the wireless module 46. The material of the first conductor 11 can be copper, aluminum, etc., preferably copper. The base 12 is used to connect the first conductor 11 to the housing 3. The base 12 is also used to cooperate with the accommodating cavity 24 of the second conductive component 2, thereby covering the accommodating cavity 24 and preventing external dust, water droplets, etc. from damaging the second conductor 22, the elastic member 23, etc. in the accommodating cavity 24. The material of the base 12 can be plastic, ceramic, or other materials with good insulation properties.

[0040] Further, such as Figure 3-4 The first conductive component 1 further includes a stepped portion 13 disposed on the base 12, which is detachably mechanically connected to the second conductive component 2. Specifically, the stepped portion 13 is configured to cooperate with the stepped cavity 25 of the second conductive component 2 to facilitate mutual positioning between the first conductive component 1 and the second conductive component 2, thereby ensuring good relative stability between the first conductive component 1 and the second conductive component 2.

[0041] Further, such as Figure 1 and 5 The input / output module 44, the angle sensor 45, and the wireless module 46 are all connected to the central processing controller 41 via a short-range wireless chip. Specifically, the short-range wireless chip facilitates wireless communication between the input / output module 44, the angle sensor 45, and the wireless module 46 and the central processing controller 41, thereby reducing the wiring harness within the control box of the present application. As a result, the control box of the present application only has a plurality of first conductive components 1 connected to the box body 3, thereby enabling rapid removal, replacement, or addition of related functional components, thereby improving maintenance efficiency.

[0042] Furthermore, the short-range wireless chip is a Bluetooth chip. Specifically, the Bluetooth chip is suitable for short-range wireless communication, which makes the short-range wireless chip of the present application have the advantages of low power consumption, small size and easy integration.

[0043] This embodiment also provides a flat single-axis photovoltaic tracking bracket, including a control box of this embodiment.
