[0002] The sunlight simulation system is a device that simulates sunlight indoors. During the simulation process, the lighting angle sometimes needs to be adjusted, which requires the system to have a tilting function. The current sunlight simulation system's tilting mechanism uses a wire rope pulley to complete the tilting through the bracket's own weight. The motor mainly controls the length of the wire rope.

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Please refer to Figures 1-4. The tilting mechanism of the sunlight simulation system provided by the present invention includes a first tilting component 1 and a second first tilting component 2. The first tilting component 1 is connected to the second tilting component 2 through a truss 3. The first tilting component 1 and the second tilting component 2 both include: a fixed shell 11; a tilting shell 12, which is movably connected to the fixed shell 11 through a tilting rotating shaft 13; a screw lift 14, which is fixed in the fixed shell 11 through a screw tilting seat 15, the input shaft of the screw lift 14 is fixedly connected to the output shaft of the motor 15, the screw nut 16 of the screw lift 14 is fixed on the tilting shell 12, and the screw 141 of the screw lift 14 is tilted, and its tilting angle matches the tilting angle of the tilting shell 12; a screw rotating shaft 17, and the screw tilting seat 15 is movably connected to the fixed shell 11 through the screw rotating shaft 17.

[0018] The fixed shell 11 is composed of a fixed shell top plate 111, a fixed shell rear plate 112, a fixed shell bottom plate 113 and a fixed shell side plate 114, and the tilting shell 12 is composed of a tilting shell bottom plate 121, a first tilting shell vertical plate 122 and a second tilting shell vertical plate 123, one end of the fixed shell 11 is fixedly connected to the second truss 23, and one end of the tilting shell 12 is fixedly connected to the third truss 24. The tilting rotation shaft 13 is provided with a rotating shaft fixing ring 25, which is used to fix the connection between the tilting rotation shaft 13 and the fixed shell 11.

[0019] If the tilt angle of the sunlight simulation system needs to be adjusted, the motor 15 is started, and the output shaft of the motor 15 is fixedly connected to the input shaft of the screw lift 14, driving the screw 141 of the screw lift 14 to rotate, thereby driving the screw nut 16 sleeved on the screw 141 to move linearly on the screw 141.

[0020] The screw nut 16 is fixed between the first tilting shell upright plate 122 and the second tilting shell upright plate 123 of the tilting shell 12, so that when the screw nut 16 makes linear motion, it drives the tilting shell 12 to rotate in a direction away from the fixed shell 11 with the tilting rotation axis 13 as the axis.

[0021] A limit switch mounting plate 19 is fixed at the connection between the fixed housing 11 and the tilting housing 12, and a position limit switch 191 and a safety limit switch 192 are fixed on the limit switch mounting plate 19. A limit block mounting seat 20 is fixed at the connection between the fixed housing 11 and the tilting housing 12, and a limit block 22 is fixed on the limit block mounting seat 20 via a limit block fixing member 21. The limit block 22 limits the angle range of the tilting to avoid exceeding the stroke. When rotating, the tilting housing 12 first triggers the position limit switch 191 during the movement, at which time the motor stops running and the tilting housing 12 moves to the specified position. If the tilting housing 12 triggers the safety limit switch 192 during the movement, it indicates that the tilting housing 12 moves beyond the specified position, and at this time the motor 15 will be powered off, thereby greatly protecting the tilting mechanism from overshoot and damage.

[0022] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
