An automatic sunlight-tracking device comprises a solar panel-mounting bracket (1), a supporting bracket (2), a pitch tracking member and a left-and-right tracking member. The solar panel-mounting bracket (1) is connected with the supporting bracket (2) through a three-dimensional subassembly (3). The pitch tracking member comprises a first transmission component and a first driving device (81) which is matched with the first transmission component. The left-and-right tracking member comprises a second transmission component and a second driving device (82) which is matched with the second transmission component. The three-dimensional subassembly (3) comprises two rotary supporting shafts (31, 32) in cross connection. The automatic sunlight-tracking device has high operating precision and a reasonable structure, and reduces operation energy consumption, and is easy to be controlled and convenient to be installed and maintained. |
