[0008] The housing includes an upper housing with its opening facing downwards and a lower housing with its opening facing upwards, which is fitted inside the upper housing. The inner wall of the upper housing is provided with a mounting plate for fixing the rotating shaft. One end of the upper surface of the upper housing has a gear hole corresponding to the position of the gear and a power button electrically connected to the light-emitting device for controlling the light-emitting device to turn on or off. The upper housing has a light-transmitting hole on the side near the gear hole.

[0009] The component mounting liner is embedded in the lower housing. The upper surface of the component mounting liner has a groove, and a light-emitting device mounting slot is formed in the groove for mounting the light-emitting device. A gear mounting slot, which is adapted to the diameter of the gear and communicates with the light-emitting device mounting slot, is formed in the groove at the position corresponding to the mounting plate.

[0010] The outer edge of the gear extends to the outside of the upper housing through the gear hole, which is used to rotate the gear by external force; multiple light-transmitting embedded lenses are evenly distributed along the circumferential direction on the gear, so that when the gear rotates, it can drive each light-transmitting embedded lens to cut into or out of the light emission path of the light-emitting device.

[0011] The content to be displayed is set on the light-transmitting embedded lens.

[0012] Furthermore, the gear has six light-transmitting embedded lenses evenly distributed along its circumference.

[0014] Furthermore, a housing alignment mark is provided on the upper housing at the center of the gear hole, and the housing alignment mark is located in the radial plane of the gear in the vertical direction;

[0015] The gear is provided with a gear alignment mark, and the housing alignment mark and the gear alignment mark cooperate with each other to determine the projection position.

[0016] Furthermore, the inner wall of the upper housing is provided with a first mounting plate and a second mounting plate for fixing the two ends of the rotating shaft, respectively; the gear is located between the first mounting plate and the second mounting plate.

[0017] Furthermore, after the upper and lower shells are fitted together, the gap between them is 0.1±0.3mm.

[0018] Furthermore, the upper surface of the component mounting liner is a vacuum-formed surface.

[0019] Furthermore, a threaded mounting hole is provided at one end of the mounting groove of the light-emitting device near the light-transmitting hole of the inner lining, and the emitting end of the light-emitting device is installed in the threaded mounting hole to prevent the light-emitting device from shaking.

Detailed Implementation

[0035] like Figure 1 As shown, a display projection device based on a gear assembly includes a housing, a component mounting liner 12, a gear assembly, and a light-emitting device 6 disposed within the housing. The gear assembly includes a rotating shaft 5 and a gear 3 rotatably mounted on the rotating shaft 5.

[0036] like Figure 2 As shown, the housing includes an upper housing 1 with its opening facing downwards and a lower housing 2 with its opening facing upwards, which is fitted inside the upper housing 1. After the upper housing 1 and the lower housing 2 are fitted together, the gap between them is 0.1±0.3mm. This gap ensures that there is a certain amount of friction between the upper housing 1 and the lower housing 2, making them fit tightly together, while also ensuring that the upper housing 1 and the lower housing 2 can be easily opened. The inner wall of the upper housing 1 is provided with a mounting plate 11 for fixing the rotating shaft 5. One end of the upper surface of the upper housing 1 is provided with a gear hole 4 corresponding to the position of the gear 3 and a power button 9 electrically connected to the light-emitting device 6 for controlling the light-emitting device 6 to turn on or off. The upper housing 1 is provided with a housing alignment mark 18 that coincides with the central axis of the gear hole 4. The side of the upper housing 1 near the gear hole 4 is provided with an upper housing light-transmitting hole 8.

[0037] like Figure 3 As shown, the mounting plate 11 includes a first mounting plate 21 and a second mounting plate 22. The first mounting plate 21 and the second mounting plate 22 form a cavity. The rotating shaft 5 passes through the first mounting plate 21, the shaft hole 16 on the gear 3 and the second mounting plate 22 in sequence and is fixedly connected to the inner side of one end of the upper housing 1.

[0038] like Figure 4 As shown, a light-transmitting hole 10 is provided on one side of the lower shell 2 at a position corresponding to the light-transmitting hole 8 of the upper shell;

[0039] like Figure 5As shown, the component mounting liner 12 is embedded in the lower housing 2. A groove 13 is formed on the upper surface of the component mounting liner 12, and a light-emitting device mounting slot 22 for mounting the light-emitting device 6 is formed within the groove 13; as shown... Figure 7 As shown, a threaded mounting hole 7 is provided at one end of the light-emitting device mounting groove 22 near the light-transmitting hole 15 of the inner lining. The emitting end of the light-emitting device 6 is installed in the threaded mounting hole 7 to prevent the light-emitting device 6 from shaking. A gear mounting groove 14, which is adapted to the diameter of the gear 3 and communicates with the light-emitting device mounting groove 22, is opened in the groove 13 at the position corresponding to the mounting plate 11. An inner lining light-transmitting hole 15, which communicates with the gear mounting groove 14, is provided on the component mounting inner lining 12 at the position corresponding to the light-transmitting hole 10 of the lower shell. The inner lining light-transmitting hole 15, the lower shell light-transmitting hole 10, and the upper shell light-transmitting hole 8 are sequentially located on the light emission path of the light-emitting device 6. Figure 6 As shown, a shaft hole 16 is provided at the center of gear 3. One end of the rotating shaft 5 passes through the shaft hole 16 and is rotatably connected to gear 3. The outer edge of gear 3 extends to the outside of the upper housing 1 through gear hole 4, which is used to rotate the gear by external force. Six light-transmitting embedded lenses 17 are evenly distributed on gear 3 along the circumferential direction, so that when gear 3 rotates, it can drive each light-transmitting embedded lens 17 to cut into or out of the light emission path of light-emitting device 6. By rotating gear 3 exposed outside the upper housing 1, the angle of gear 3 can be adjusted to display the content to be displayed on the six light-transmitting embedded lenses 17 at different angles. Gear 3 is provided with gear alignment mark 19. Rotating gear 3 will align housing alignment mark 18 and gear alignment mark 19 to determine the position of projection device and ensure that the projected image of projection device will not be offset.

[0040] After the upper shell 1, lower shell 2 and component mounting liner 12 are installed, the light beam emitted by the light-emitting device 6 passes through the light-transmitting embedded lens 17 on the gear 3, the light-transmitting hole 15 in the liner, the light-transmitting hole 10 in the lower shell and the light-transmitting hole 8 in the upper shell in sequence and then shines out, projecting the content to be displayed on the light-transmitting embedded lens 17 onto the external screen or white wall.
