The lens adjusting device is simple in structure, the structure of the device is set in the process, the lens adjusting device is adopted to adjust the lens 17, operation is simple and convenient, and applicability is better.
In an embodiment of the present invention, at each of the fastening portions of the optical engine case 1 and the lens holder 2, a first sliding groove 19 penetrating through a corresponding wall (e.g. the top wall 4/the bottom wall 8/the side wall 6) of the optical engine case 1 and having an open end is formed on the corresponding wall, and the first sliding groove 19 may be configured in various shapes, for example: the shape of the joint can be rectangular, semicircular and rectangular, or semi-elliptical. The lens holder 2 has a cavity 20 inside a corresponding wall plate (e.g. top wall 5/bottom wall 9/side wall 7), and the wall plate has a second sliding groove 21 penetrating the wall plate and communicating with the cavity 20, the cavity 20 can be set to any shape, but it is necessary to ensure that the inner surface of the cavity 20 contacting with the corresponding sheet-like adjusting member 11 is closely attached to the outer surface of the sheet-like adjusting member 11, so as to ensure that the cavity 20 can be driven to integrally move along the direction perpendicular to the contact surface of the two after the sheet-like adjusting member 11 is inserted into the cavity 20, wherein a preferred setting mode is: the cavity 20 is designed to be completely matched with the corresponding sheet-shaped adjusting piece 11, for example, both the sheet-shaped adjusting piece 11 and the cavity 20 are designed to be rectangular, and the rectangular body matched with the cavity 20 is wrapped outside the rectangular body matched with the sheet-shaped adjusting piece 11, so that the sheet-shaped adjusting piece 11 is inserted into the cavity 20 and then forms a completely matched whole with the cavity 20, and can move integrally as a whole, thereby greatly improving the adjusting precision of the lens adjusting device. Corresponding slice regulating part 11 is pegged graft in cavity 20 inside back, and corresponding adjusting screw 10 runs through the screw through-hole 12 of second spout 21 and corresponding slice regulating part 11, its constant head tank 13 with 19 joints of first spout, specifically do: after the positioning groove 13 is clamped in the first sliding groove 19, the upper and lower groove walls of the positioning groove 13 are clamped with the corresponding wall plates on the two sides of the first sliding groove 19. The shape of second slide groove 21 may be various, for example, it may be a rectangle, it may be a semicircle at both ends, and it may be a rectangle in the middle, and second slide groove 21 may be an ellipse in order to reduce sliding friction. When the lens holder 2 moves up and down along the vertical direction relative to the optical engine under the driving of the sheet-shaped adjusting piece 11, the adjusting screw 10 at the buckling position of the side walls of the optical machine shell 1 and the lens holder 2 can slide up and down along the corresponding second sliding groove 21 without rotating, so that the sheet-shaped adjusting piece 11 is prevented from displacing relative to the adjusting screw 10, and the linkage effect that the lens holder 2 moves up and down and moves left and right relative to the optical engine is eliminated. Similarly, when the lens holder 2 is driven by the sheet-shaped adjusting member 11 to move left and right relative to the optical engine along the horizontal direction, the adjusting screws 10 at the buckling positions of the top wall and/or the bottom wall of the optical engine shell 1 and the lens holder 2 can slide left and right along the corresponding second sliding grooves 21 without rotating, so that the sheet-shaped adjusting member 11 is prevented from displacing relative to the adjusting screws 10, and the linkage effect of left and right movement and up and down movement of the lens holder 2 relative to the optical engine is eliminated. Thus, in a specific arrangement, the sliding direction of first slide groove 19 and the sliding direction of second slide groove 21 are perpendicular to each other, for example, if first slide groove 19 is a semi-elliptical shape and second slide groove 21 is an elliptical shape, the major axis direction of first slide groove 19 and the major axis direction of second slide groove 21 are perpendicular to each other.
In practical implementation, in order to simplify the structure of the lens adjusting device, a first sliding groove 19 is usually formed on the top wall 4/bottom wall 8 and the side wall 6 of the optical housing 1, and correspondingly, a second sliding groove 21 and a cavity 20 communicated with the second sliding groove 21 are also formed on the top wall 5/bottom wall 9 and the side wall 7 of the lens holder 2. If the structure of the lens adjusting device is desired to be simpler, when the lens adjusting device is specifically arranged and the lens is adjusted by the lens adjusting device, the operation is simpler and more convenient, only the top wall 4 or the bottom wall 8 and the side wall 6 of the optical machine shell 1 are respectively provided with the first sliding groove 19, and the second sliding groove 21 and the cavity 20 on the lens bracket 2 are correspondingly arranged with reference to the optical machine shell 1. For example, a first sliding groove 19 is formed on the top wall 4 and one side wall 6 of the optical machine housing 1, and correspondingly, a second sliding groove 21 and a cavity 20 communicated with the second sliding groove 21 are formed on the top wall 5 and one side wall 7 of the lens holder 2; or, a first sliding groove 19 is respectively formed on the bottom wall 8 and one side wall 6 of the optical machine housing 1, and correspondingly, a second sliding groove 21 and a cavity 20 communicated with the second sliding groove 21 are respectively formed on the top wall 5 and one side wall 7 of the lens holder 2.
The first sliding groove 19 may be disposed at any position of the corresponding wall plate of the optical engine housing 1, and in order to improve the adjustment accuracy of the lens adjusting apparatus, the first sliding groove 19 is typically disposed at an intermediate position of the corresponding wall plate of the optical engine housing 1, for example, the first sliding groove 19 on the top wall 4/bottom wall 8 of the optical engine housing 1 is disposed at an intermediate position with a distance equal to the distance between the two side walls 6 thereof, and the first sliding groove 19 on the side wall 6 of the optical engine housing 1 is disposed at an intermediate position with a distance equal to the distance between the top wall 4 and the bottom wall 8. Accordingly, the second sliding groove 21 is disposed at the middle position of the corresponding wall plate of the lens holder 2, and the specific arrangement can refer to the arrangement of the optical machine housing 1, which is not described in detail herein.
In the lens adjusting device 100 provided by the embodiment of the present invention, the optical engine housing 1 and the lens holder 2 are fastened together, and at each fastening position, the positioning groove 13 of the adjusting screw 10 is fastened to a corresponding wall plate of the optical engine housing 1, for example, the positioning groove 13 of the adjusting screw 10 is fastened to a first sliding groove 19 disposed on the corresponding wall plate of the optical engine housing 1, and other portions of the adjusting screw 10 penetrate through a corresponding wall plate of the lens holder 2 (for example, a second sliding groove 21 disposed on the corresponding wall plate of the lens holder 2) and a threaded through hole 12 of a corresponding sheet-shaped adjusting member 11, and the thread of the threaded through hole 12 is matched with the thread of the adjusting screw 10, so that when the adjusting screw 10 is screwed or loosened, the adjusting screw 10 is kept in a fastened state with the optical engine housing 1, and cannot generate relative displacement, so that the rotation of the adjusting screw 10 is transmitted to the threaded through the mutual matching, the sheet-shaped adjusting part 11 moves left and right relative to the corresponding adjusting screw 10 along the horizontal direction or moves up and down relative to the corresponding adjusting screw 10 along the vertical direction, so as to drive the lens holder 2 to move left and right relative to the optical machine housing 1 (optical engine) along the horizontal direction or move up and down relative to the optical machine housing 1 (optical engine) along the vertical direction, thereby realizing the adjustment of the deviation between the optical engine and the lens 17.
When the lens adjusting device 100 is used to adjust the deviation between the lens 17 of the projector and the dmd 15 of the optical engine, if the threads of the adjusting screw 10 or the threads of the threaded through hole 12 of the sheet-shaped adjusting member 11 are worn or there is a certain slight deviation between the threads, during the specific adjustment, the lens adjusting device itself may deflect, that is, when the lens holder 2 moves along with the sheet-shaped adjusting member 11, the lens adjusting device itself rotates along the central axis thereof, resulting in different moving distances of the left and right sides or the upper and lower ends of the lens holder 2, which results in an inaccurate adjustment precision.

When the lens holder 2 moves up and down along the vertical direction relative to the optical engine housing 1 (or the optical engine) under the driving of the corresponding sheet-like adjusting member 11, each vertical adjusting rod 24 slides axially along the respective vertical rail 26, and the lens adjusting device is ensured not to deflect due to the parallel arrangement of all the vertical rails 26. Similarly, when the lens holder 2 is driven by the corresponding sheet-shaped adjusting member 11 to move left and right relative to the optical engine housing 1 (optical engine) along the horizontal direction, each horizontal adjusting rod 23 slides axially along the respective horizontal rail 25, and since all the horizontal rails 25 are arranged in parallel, the lens adjusting device is ensured not to deflect.
