[0002] At present, a light source mechanism such as a laser light source and an optical element such as a light-emitting lens that performs light processing on a light beam emitted from a light source mechanism are generally disposed in the projection device, so that the light beam is reduced as much as possible during the transmission process. Loss and accurate transmission through optical components to light-receiving components such as square bars, light valves, etc., and further projection onto the screen through the projection lens, requires that the optical components be accurately positioned.

technical problem

[0003] However, since the light source mechanism, the optical element, or the light-receiving member of the projection device inevitably have production errors in the production process, there are installation errors in the process of installing the light source mechanism and the optical element, which ultimately leads to The central axis of the light beam emitted by the light source mechanism and the central axis of the optical element into which the light beam is incident, during the transmission of the light beam through the plurality of optical elements, the central axis of the light beam and the central axis of each optical element into which the light beam is incident, There may be a misalignment between the central axis of the beam emitted by the optical element and the central axis of the light receiving member into which the outgoing beam is incident, resulting in a large loss of the beam emitted by the source mechanism during transmission, resulting in partial beam not being Projection to the screen reduces projection quality such as projection brightness.

Therefore, a misalignment occurs between the center axis of the light beam emitted from the light exit lens 02 to the light receiving member such as a square bar or a light valve and the central axis of the light receiving member, resulting in poor projection quality of the projection device.

[0082] In this embodiment, an optical component adjustment assembly includes a mounting bracket and a trimming assembly, wherein the mounting bracket has a mounting hole for mounting the optical component; the trimming component is disposed on the mounting bracket, and the trimming component is used to adjust the mounting bracket s position.

[0083] In this way, when assembling, the optical component is mounted on the mounting hole provided by the mounting bracket, and by adjusting the fine adjustment component, the position of the mounting bracket can be adjusted, thereby achieving the purpose of adjusting the position of the optical component, thereby ensuring the center of the optical component. The axis is accurately aligned with the central axis of the light receiving member located downstream of the optical element in the beam propagation direction.

[0084] It should be noted that the optical component may be a lens, a diffusion sheet, a reflective lens, or the like. In the embodiment, the optical component is preferably an exit lens, and the optical component adjustment component is exemplified by mounting the optical lens. Description. Of course, according to the actual use requirements, the corresponding optical components are selected for installation.

[0085] It should be noted that the mounting bracket can be installed in the corresponding projection device as a whole structure. Of course, it is not excluded to install the mounting bracket in the light-emitting housing 13 and then installed in the projection device, in this embodiment. Unless otherwise specified, the mounting bracket is mounted on the light-emitting housing 13 as a preferred mounting method, and the optical component is preferably a light-emitting lens to introduce the optical component adjusting component in detail. It is known that the component adjusting component can also be applied. For positional adjustment of other types of lenses or optical elements such as diffusers, mirrors, etc., these optical elements are mounted at corresponding locations in the projection device depending on their different effects on the beam in the projection device.

[0086] In the present embodiment, with reference to FIGS. 2 and 3, a preferred arrangement of the optical component adjustment assembly is as follows: The mounting bracket includes a first bracket 1 and a second bracket 2, wherein the first bracket 1 is provided with a light lens for mounting The mounting hole, the first bracket 1 is connected to the second bracket 2. The second bracket 2 is provided with a frame hole opposite to the mounting hole, and the hole diameter of the frame hole is preferably set to be slightly larger than the hole diameter of the mounting hole, so that the whole of the light-emitting lens mounted in the mounting hole faces the frame hole to receive the light beam without being subjected to the The effect of a change in the position of a stent. In addition, the frame hole can also be replaced by a shelf opening, that is, as long as the second bracket is provided with an open space for the light beam to pass through and is directed toward the mounting hole. In this embodiment, for the transmission direction of the light beam through the optical element adjustment component, the first bracket 1 is located on the further downstream side of the light beam than the second bracket 2, and therefore, the light beam is transmitted from the second bracket 2 during the transmission.

It is further known that, as described above, the rotation of the first adjusting member 3 in the forward and reverse directions by the hex driver can cause the second holder 2 to move in both Y+ and Y- directions as shown in FIG.

[0087] Further, in order to make the force applied by the first adjusting member 3 to the second bracket 2 more stable, the movement of the second bracket 2 is also made smoother, and the fine adjustment assembly further includes the first elastic member 5, the first elastic The member 5 is preferably selected as a spring and is in a compressed state in an initial state, and the first elastic member 5 can provide a certain preload to the second bracket 2. Specifically, one end of the first elastic member 5 abuts against the second bracket 2, and the other end of the first elastic member 5 can abut the light-emitting outer casing 13. In addition, the other end of the first elastic member can also be composed of a spring piece. One end is fixed, and the other end of the elastic piece is fixed on the first bracket, and a point is arranged between the two ends of the elastic piece, and the fulcrum is fixed with a light-emitting outer casing or a certain part of the projection device, so that one end of the elastic piece can support the first The elastic member cooperates with the first adjusting member to the first elastic member to increase or decrease the amount of compression thereof
