In this way, the flip drive device can drive the headlight to flip, so that the headlight can be used in complex road conditions and rich usage scenarios.

[0048] Please refer to Figure 1-Figure 6 , Figure 1 is a schematic diagram of the structure of the flip drive device provided in an embodiment of the present application, Figure 2 is a front view of the flip drive device provided in an embodiment of the present application, Figure 3 yes Figure 2 A cross-sectional view of the flip drive device at AA, Figure 4is an exploded schematic diagram of an embodiment of the flip drive device provided by the present application, Figure 5 is an exploded schematic diagram of another embodiment of the flip drive device provided by the present application, Figure 6 1 is an exploded schematic diagram of another embodiment of the flip drive device provided by the present application. The flip drive device 100 may include but is not limited to a first housing assembly 110, a power device 120, a worm 130, a worm wheel 140 and a drive shaft 150. The first housing assembly 110 has a first accommodating chamber 110a and a first outlet 1122 connected to the first accommodating chamber 110a. The first housing assembly 110 includes a first housing 111 and a second housing 112 covered with the first housing 111. The first housing 111 is provided with a first accommodating groove 1111. The second housing 112 is provided with a second accommodating groove 1121. The first accommodating groove 1111 and the second accommodating groove 1121 constitute the first accommodating chamber 110a. The first outlet 1122 is provided on the second housing 112. The power device 120 is provided in the first accommodating chamber 110a. The worm 130 is provided in the first accommodating chamber 110a and is drivingly connected to the power device 120. The worm wheel 140 is disposed in the first accommodating chamber 110a and is in transmission connection with the worm 130. The worm wheel 140 meshes with the worm 130. A portion of the drive shaft 150 is disposed in the first accommodating chamber 110a and is in transmission connection with the worm wheel 140. Another portion of the drive shaft 150 passes through the first outlet 1122. Driven by the power device 120, the drive shaft 150 can drive the object to flip.

[0049] Alternatively, the power device 120 may be an electric motor.

[0050] It is understandable that when the above-mentioned object is a motor vehicle headlight, the flip driving device 100 can drive the motor vehicle headlight to flip, so that the motor vehicle headlight can be applied to complex road conditions and rich usage scenarios. Specifically, under the road conditions of an uphill section at night, the motor vehicle headlight can be driven by the flip driving device 100 to flip around the first direction, so that the motor vehicle headlight can illuminate a longer uphill section. Under the road conditions of a downhill section at night, the motor vehicle headlight can be driven by the flip driving device 100 to flip around the second direction, so that the motor vehicle headlight can illuminate a longer downhill section. Among them, the first direction refers to one of the clockwise direction and the counterclockwise direction. The second direction refers to the other of the clockwise direction and the counterclockwise direction. Further, when the uphill section or downhill section where the motor vehicle is located is bumpy, the setting of the transmission connection between the worm wheel 140 and the worm 130 can keep the flip angle of the motor vehicle headlight unchanged, thereby maintaining good lighting conditions. Further, the user can also drive the motor vehicle headlight to flip up and down continuously through the flip driving device 100 to achieve the purpose of being cool.
