It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, the use of the directional words such as "up and down" refers to the up and down as defined in the normal use state of the projector, unless otherwise specified; use of directional words such as "inner and outer" refers to the inner and outer of a particular structural profile; terms such as "first, second, third and fourth" are used merely to distinguish one element from another and are not sequential or significant.
As shown in fig. 1 to 9, the present disclosure provides an optical module angle adjusting mechanism, which includes:
the optical-mechanical support 1 is used for installing an optical-mechanical module, and the optical-mechanical support 1 is rotatably arranged in the projector shell 10 around a first axis A parallel to a horizontal plane;
an adjusting component 2 for being installed in the projector shell 10, wherein the adjusting component 2 comprises an actuating piece 21 and a moving block 22;
an inclined sliding groove 221 is formed in one of the moving block 22 and the optical machine support 1, a sliding block 220 in sliding fit with the inclined sliding groove 221 is arranged on the other one, and the inclined sliding groove 221 is arranged at an angle with the vertical plane and the horizontal plane;
the actuating member 21 is connected to the moving block 22 and is used for driving the moving block 22 to move along a second axis B parallel to the horizontal plane, and the moving block 22 can rotate around a third axis D parallel to the first axis a, so that the slider 220 can slide relative to the inclined sliding groove 221 and drive the optical machine support 1 to rotate around the first axis a.
In the above technical solution, firstly, by disposing the optical-mechanical support 1 in the projector housing 10, and the optical-mechanical support 1 can rotate around the first axis a parallel to the horizontal plane, since the optical-mechanical module (not shown) is mounted on the optical-mechanical support 1, the optical-mechanical module can also rotate around the first axis a parallel to the horizontal plane; secondly, this ray apparatus module angle adjustment mechanism still includes adjusting part 2, and this adjusting part 2 can make ray apparatus support 1 rotate for foretell first axis A.
In particular, the adjustment assembly 2 comprises an actuating member 21 and a moving block 22 connected to each other, and the actuating member 21 is able to drive the moving block 22 in movement along a second axis B parallel to the horizontal plane. One of the moving block 22 and the optical machine support 1 is formed with an inclined sliding groove 221, and the other is provided with a sliding block 220 in sliding fit with the inclined sliding groove 221. When the actuator 21 drives the moving block 22 to move along the second axis B, the slider 220 can slide relative to the inclined sliding groove 221, and since the inclined sliding groove 221 is disposed at an angle to both the vertical plane and the horizontal plane, that is, the inclined sliding groove 221 is inclined in the vertical direction, when the slider 220 slides relative to the inclined sliding groove 221, the carriage 1 also moves in the vertical direction, that is, the carriage 1 rotates clockwise or counterclockwise around the first axis a parallel to the horizontal plane. In the process of rotation, in order to avoid interference caused by rotation of the moving block 22 to the optical engine bracket 1, the moving block 22 itself should also be capable of rotating around a third axis D parallel to the first axis a, so as to ensure normal rotation of the optical engine bracket 1, thereby adjusting the angle of the optical engine module arranged on the optical engine bracket 1 relative to the horizontal plane, so that the optical engine module is parallel to the horizontal plane, avoiding the condition that the optical engine module is not accurately positioned in the process of assembling the optical engine module into the projector housing 10, avoiding distortion of the projection picture of the optical engine module, and improving the resolution and the imaging quality of the projection picture.

The adjusting assembly 2 is simple in structure and convenient to operate by an operator.

In addition, the moving block 22 is located between the two mounting plates 232, and a gap is provided between the bottom surface of the moving block 22 and the bottom plate 231, so that the moving block 22 can rotate relative to the lead screw.

The size of the gap in the up-down direction can be set by itself according to the size of the rotation angle of the optical machine support 1 relative to the horizontal plane, and the size of the gap C in the up-down direction should also be increased adaptively due to the increase of the rotation angle.
