[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Example 1

[0034] Refer to the attached Figure 2-3 A lamp stand flipping device of this embodiment includes a flipping component 210 and a motor 210. The flipping components 210 are set to two, and the motor 230 is connected to any of the flipping components 210. The motor 230 is used to drive the flipping component 210.

[0035] The flip assembly 210 includes a fixed frame 211 and a spiral elevator 212, the bearing end of the spiral elevator 212 is rotatably connected to the fixed frame 211, the spiral rod end of the spiral elevator 212 is connected to the flip frame 213, one end of the flip frame 213 is connected to the spiral rod end of the spiral elevator 212, and the other end of the flip frame 213 is rotatably connected to the fixed frame 211.

[0036] The motor 230 is connected to the spiral elevator 212 to drive the spiral elevator 212 to flip, and the rotation of the motor 230 drives the spiral elevator 212 to flip; the motor 230 and the spiral elevator 212 are arranged in coordination so that when the motor 230 drives the spiral elevator 212 to rotate forward and reverse, the screw rod end of the spiral elevator 212 drives the flipping frame 213 to flip. Specifically, when the motor 230 drives the spiral elevator 212 to rotate forward, the screw rod end of the spiral elevator 212 drives the flipping frame 213 to rise, thereby driving the connected lamp to rise; when the motor 230 drives the spiral elevator 212 to rotate reversely, the screw rod end of the spiral elevator 212 drives the flipping frame 213 to descend, thereby driving the connected lamp to descend.

[0037] It also includes a long shaft 220 and a coupling 240, wherein two couplings 240 are provided, and both ends of the long shaft 220 are respectively connected to the couplings 240, and the couplings 240 are connected to the screw elevator 212. When the motor 230 is driven, the motor 230 drives the long shaft 220 to rotate through the coupling 240, thereby driving the screw elevator 212 and the flip frame 213 away from the side of the motor 230 to flip.

[0038] The fixed frame 211 includes a welding plate 211A and a rotating shaft 211B. The bearing end of the spiral elevator 212 is connected to a fixed bracket 212A. The fixed bracket 212A is connected to the welding plate 211A through the rotating shaft 211B. When the motor 230 is driven, the spiral elevator 212 is flipped through the rotating shaft 211B.

[0039] The spiral jack 212 is equipped with a self-locking device. When the motor 230 stops, the self-locking device locks the spiral jack 212 to prevent the spiral rod end of the spiral jack 212 from rotating. The spiral jack 212 is equipped with a speed reduction device. When the motor 230 stops, the speed reduction device slows down the spiral jack 212 to stabilize the spiral jack 212 after it stops rotating, thereby reducing the shaking of the lamp.

[0040] It also includes a second rotation axis 214, and the flip frame 213 is connected to the fixed frame 211 via the second rotation axis 214. It also includes a combined frame 250, and both ends of the combined frame 250 are connected to the fixed frame 211 respectively, and the flip assembly 210 is fixedly connected via the combined frame 250.

[0041] When the illumination angle of the lamp needs to be adjusted, the motor 230 is driven, and the motor 230 drives the drive assembly 210 connected to the motor 230, and at the same time drives the long shaft 220 to rotate by driving the coupling 240. The long shaft 220 rotates, driving the drive assembly 210 away from the motor 230 to rotate, and the spiral elevator 212 provided in the drive assembly 210 rotates, driving the flip frame 213 to flip, thereby driving the angle of the lamp to be adjusted, changing the illumination angle of the light, and realizing that the light is directly projected from the front windshield and rear windshield of the vehicle into the vehicle interior, thereby simulating sunlight radiation.

[0042] Example 2

[0043] Refer to the attached Figure 1 A combination lamp stand includes the flip device 200 described in Example 1, wherein two flip devices 200 are provided, and the flip device 200 is connected to a fixed-end combination lamp 100, and both ends of the fixed-end combination lamp 100 are respectively connected to the flip devices 200.

[0044] The flip device 200 is connected to the flip end combination lamp 300 in a direction away from the fixed end combination lamp 100. By adjusting the angle of the flip device 200, the flip end combination lamp 300 is driven to rotate and the light angle of the lamp is adjusted.

[0045] When a vehicle undergoes a whole-vehicle solar radiation test, it is used to understand the weather resistance and stability of the vehicle under long-term exposure to solar radiation, so as to improve the vehicle design and material selection. By adjusting the angle of the flip device 200 and then adjusting the angle of the combined lamp holder, the light is made to shine directly from the front windshield and rear windshield of the vehicle into the vehicle interior, thereby simulating sunlight radiation.

[0046] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
