[0028] With the continuous development of laser projection technology, the demand of users for separated light source and multi-directional adjustment of projected picture is increasing. Optical fiber can be used to transfer laser to realize the separation of light engine and light source, and the light engine can be divided into multiple adjustable modules to realize multi-dimensional adjustment of the picture. Please refer to Figure 5 , the optical fiber 8 of the existing projection device is fixed on the light engine 9. When adjusting the rotation of the light engine 9 around the support rod 10, the optical fiber 8 will move with the movement of the light engine 9. Frequent movement of the optical fiber 8 can easily cause damage to the optical fiber 8, which poses a safety hazard.
[0029] Therefore, in the embodiments of the present application, a projection device and a carrier system are provided to solve or partially solve the above problems.
[0030] Please refer to Figures 1-2 , which shows a structural schematic diagram of a projection device provided by an embodiment of the present application. The device comprises:
[0031] The base 1, the support assembly 2, the shell 3, the mirror 4, the light machine compound eye 5, the rotating part 6 and the transmission assembly 7.
[0032] The support assembly 2 has oppositely arranged first and second parts 21 and 22, the first part 21 is fixedly connected with the base 1, and the light outlet of the optical fiber 8 is fixedly arranged on the second part 22, the support assembly 2 further comprises a third part 23 oppositely arranged with the first part 21, the third part 23 is hinged with the shell 3 through a connecting shaft 31, and the second part 22 and the third part 23 are located on the same side of the first part 21.
[0033] The light machine compound eye 5 and the rotating part 6 are fixedly arranged on the inner wall of the shell 3, and the rotating part 6 is coaxially arranged with the connecting shaft 31.
[0034] The transmission assembly 7 comprises a first driven part 71, a second driven part 72 and a positioning part 73, the first driven part 71 and the second driven part 72 are arranged on the positioning part 73, the positioning part 73 is fixedly arranged on the third part 23, the rotating part 6 is used in cooperation with the first driven part 71 to drive the first driven part 71 to rotate.
[0035] The first driven part 71 and the second driven part 72 are movably connected, for driving the second driven part 72 to rotate, the mirror 4 is arranged on the second driven part 72 and corresponds to the light outlet of the optical fiber 8, and the light beam emitted by the optical fiber 8 is irradiated to the light uniform part of the light machine compound eye 5 through the mirror 4.
[0036] The second driven part 72 is coaxially arranged with the connecting shaft 31, and the axis of the connecting shaft 31 is located on the mirror surface of the mirror 4, in the case that the shell 3 rotates, the rotating part 6 and the light machine compound eye 5 are driven to rotate, the first driven part 71 is driven to rotate by the rotating part 6, the second driven part 72 is driven to rotate by the first driven part 71, and the mirror 4 is driven to rotate, so that the light beam emitted by the optical fiber 8 is irradiated to the light uniform part of the light machine compound eye 5 through the mirror 4.
[0037] The base 1 is used for being mounted at a preset position of a support device, and the support device is used for fixing a projection device.
[0038] It should be known that the shell 3 can rotate around the connecting shaft 31, the shell 3 can move relative to the base 1, and the light outlet of the optical fiber 8 is fixed relative to the base 1, so that the optical fiber 8 is fixed when the shell 3 rotates, the frequent movement of the optical fiber 8 with the shell 3 can be avoided, and the damage of the optical fiber 8 can be avoided.
[0039] It should be noted that the light machine compound eye 5 is fixed on the inner wall of the shell 3, and has a light uniformizing part for uniformly distributing the received light beam to the designated area. The light beam emitted by the optical fiber 8 needs to be irradiated to the light uniformizing part of the light machine compound eye 5 after passing through the mirror 4, so as to ensure the normal projection of the projector.
[0040] When the shell 3 rotates, the light uniformizing part of the light machine compound eye 5 rotates synchronously with the shell 3, and the mirror 4 is fixed on the third part 23 and does not rotate with the shell 3. At this time, the light beam emitted by the optical fiber 8 cannot normally irradiate to the light uniformizing part of the light machine compound eye 5 after passing through the mirror 4, that is, it cannot normally project, so when the shell 3 rotates, the mirror 4 needs to be adjusted synchronously to rotate correspondingly, so that the light beam emitted by the optical fiber 8 can irradiate to the light uniformizing part of the light machine compound eye 5 after passing through the mirror 4, so as to ensure the correctness of the projection picture.
[0041] Therefore, the application sets a transmission assembly 7 for transmitting the rotation amount of the shell 3 to the mirror 4, so as to realize the rotation of the shell 3 driving the mirror 4. When the shell 3 rotates, the rotating part 6 also rotates with the shell 3, the rotating part 6 drives the first driven part 71 to rotate, and then drives the second driven part 72 to rotate, and then drives the mirror 4 to rotate, so as to realize the purpose of the rotation of the shell 3 driving the mirror 4, so that in the process of the rotation of the shell 3, the light beam emitted by the optical fiber 8 can irradiate to the light uniformizing part of the light machine compound eye 5 after passing through the mirror 4, and the projection device can dynamically adjust the position of the picture under the condition of ensuring the unchanged picture quality.
[0042] Further, the rotation speed of the shell 3 is twice the rotation speed of the mirror 4, and the rotation direction of the mirror 4 is the same as the rotation direction of the shell 3.
[0043] In an alternative embodiment, please refer to Figure 3 , wherein the arrowed straight line represents the propagation path of the light beam, the light outlet of the optical fiber is fixed on the second part of the support assembly 2, the light beam emitted by the optical fiber irradiates to the light uniformizing part of the light machine compound eye after passing through the mirror 4, and the projection is realized. Please refer to Figure 4 , when the shell 3 rotates counterclockwise by 45° on the basis of Figure 3 , the mirror 4 needs to rotate counterclockwise by 22.5°, so as to ensure that the light beam emitted by the optical fiber irradiates to the light uniformizing part of the light machine compound eye after passing through the mirror 4, and the normal projection is realized.
[0044] Specifically, the rotating part 6 is fixed on the inner wall of the shell 3, and the rotating part 6 is coaxially arranged with the connecting shaft 31.
[0045] An example is that when the shell is forced to rotate, the rotating part synchronously rotates around the connecting shaft.
[0046] Another example is that when the rotating part is forced to rotate around the connecting shaft, the shell synchronously rotates around the connecting shaft.
[0047] It should be noted that the rotating member can be a gear or a belt pulley.
[0048] In one example, the rotating member is a first gear, the first driven member is a second gear, the second driven member is a third gear, the second gear and the fourth gear are arranged on the same rotating shaft, and the fourth gear is used in cooperation with the third gear. When the first gear rotates, the first gear drives the second gear and the fourth gear to rotate, the fourth gear drives the third gear to rotate, and the third gear drives the mirror to rotate.
[0049] In another example, the rotating member is a first belt pulley, the first driven member is a second belt pulley, the second driven member is a third gear, the second belt pulley and the fourth gear are arranged on the same rotating shaft, and the fourth gear is used in cooperation with the third gear. When the first belt pulley rotates, the first belt pulley drives the second belt pulley and the fourth gear to rotate, the fourth gear drives the third gear to rotate, and the third gear drives the mirror to rotate.
[0050] In one example, the rotating member is a first gear, the first driven member is a second gear, the second driven member is a third gear, the second gear and the fourth gear are arranged on the same rotating shaft, and the fourth gear is used in cooperation with the third gear. When the first gear rotates, the first gear drives the second gear and the fourth gear to rotate, the fourth gear drives the third gear to rotate, and the third gear drives the mirror to rotate. Figures 1-2 In another example, the rotating member is a first belt pulley, the first driven member is a second belt pulley, the second driven member is a third gear, the second belt pulley and the fourth gear are arranged on the same rotating shaft, and the fourth gear is used in cooperation with the third gear. When the first belt pulley rotates, the first belt pulley drives the second belt pulley and the fourth gear to rotate, the fourth gear drives the third gear to rotate, and the third gear drives the mirror to rotate.
[0051] It should be noted that the housing 3 rotates synchronously with the rotating member 6, and in the case of rotating the rotating member 6, the rotating member 6 drives the first driven member 71 to rotate, the first driven member 71 drives the second driven member 72 to rotate, and when the second driven member 72 rotates, the mirror 4 rotates around the axis of the connecting shaft 31, that is, the distance between the mirror 4 and the outlet of the optical fiber 8 remains unchanged, only the angle of the mirror 4 changes, and the rotation of the housing 3 can drive the mirror 4 to rotate.
[0052] Therefore, during the rotation or static state of the housing 3, the light beam emitted by the optical fiber 8 can be irradiated to the light homogenizing part of the compound eye 5 through the mirror 4, thereby ensuring the normal work of the projection device. On the one hand, the optical fiber can be prevented from moving with the light machine, thereby reducing the safety hazard of the optical fiber. On the other hand, the working efficiency of the projector is greatly improved, and the user's viewing experience is also improved.
