Abstract

Disclosed is a projector ( 1 ), comprising a projector body ( 10 ) with a lens ( 12 ), and a light reflection assembly ( 20 ) for adjusting a projecting direction of the lens ( 12 ). The light reflection assembly ( 20 ) comprises a reflective mirror ( 23 ), and the light reflection assembly ( 20 ) is provided to be rotatably connected with the projector body ( 10 ). During the rotation, a mirror face of the reflective mirror ( 23 ) always faces towards the lens ( 12 ), so that the reflective mirror ( 23 ) adjusts the angle of the projecting direction between the mirror face and the lens ( 12 ) with the rotation of the light reflection assembly ( 20 ), so as to adjust the projecting location of the lens ( 12 ) by means of the rotation of the reflective mirror ( 23 ), such that the projecting direction can be changed without moving the projector ( 1 ).

First claim

What is claimed is:

1. A projector comprising:
a projector body having a lens;
a light reflection assembly for adjusting a projection direction of the lens;
wherein the light reflection assembly includes a reflective mirror, wherein the reflective mirror is rotatably connected to the projector body, and wherein during rotation, a mirror surface of the reflective mirror always faces towards the lens; and
a second lens cover for protecting the lens, the second lens cover being connected to the projector body,
wherein the second lens cover includes a through hole for the projected image light from the lens to pass through; and
wherein the light reflecting assembly further includes a second support frame, the second support frame having a shape and size adapted to the thorough hole, the second support frame being pivotally connected to the second lens cover, wherein the second support frame has a closed state where it blocks the through hole, and an open state where it is separated from the through hole, and wherein the reflective mirror is fixedly connected to the second support frame.

2. The projector of claim 1 , wherein the second support frame includes a second mounting plate, wherein the second mounting plate is pivotally connected to the second lens cover; and
wherein the second mounting plate has a second mounting slot for mounting the reflective mirror, and wherein the reflective mirror is accommodated in the second mounting slot.

3. The projector of claim 1 , wherein the second lens cover is rotatably connected to the projector body, wherein when the second lens cover is rotated to a predetermined position relative to the projector body, the second lens cover supports the projector body.

4. A projector comprising:
a projector body having a lens; and
a light reflection assembly for adjusting a projection direction of the lens;
wherein the light reflection assembly includes a reflective mirror, wherein the reflective mirror is rotatably connected to the projector body, and wherein during rotation, a mirror surface of the reflective mirror always faces towards the lens, and
wherein the light reflecting assembly further includes a base and a third support frame pivotally connected to the base, wherein the reflective mirror is fixedly connected to the third support frame, and wherein the base is detachably attached to the projector body.

5. The projector of claim 4 , wherein the third support frame includes a third mounting plate, wherein the third mounting plate is pivotally connected to the base; and
wherein the third mounting plate has a third mounting slot for mounting the reflective mirror, and wherein the reflective mirror is accommodated in the third mounting slot.

6. The projector of claim 4 , wherein a housing of the projector body is magnetic, wherein the light reflecting assembly further includes a magnetic member having a magnetic property corresponding to that of the housing, and wherein the magnetic member and the housing cooperate to connect the base to the projector body.
