Description

Bidirectional projection device

Technical Field

The utility model belongs to the technical field of projection equipment, concretely relates to two-way projection arrangement.

Background

A projector, also called a projector, is a device that can project images or videos onto a curtain, and can be connected with a computer, a VCD, a DVD, a BD, a game machine, a DV, etc. through different interfaces to play corresponding video signals. An existing projector includes a light emitting module, a lens, and a case, the light emitting module is disposed inside the case, a light path of the light emitting module passes through the lens, light of the light emitting module is projected onto a wall or a screen through the lens, generally, one side of the lens becomes a front side, and a side of the lens opposite to the front side is called a rear side. The projector generally projects on one side of a television wall, the indoor layout of some existing families is a through structure of a living room and a dining room, the wall surface right opposite to the television wall of the living room is mostly a hollow wall, when people want to watch television at meals, the television wall is far away and is not beneficial to watching, the projector cannot project to the wall of the dining room, the general projector cannot rotate by 180 degrees, if the rotation mechanism is additionally arranged, the rotation can be realized by 180 degrees, but due to the limitation of focal length, the distances between the front wall and the rear wall are generally inconsistent or the difference value is large, and the same lens cannot meet the condition of back projection.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a two-way projection arrangement for provide the projection that provides positive and negative direction respectively.

The technical proposal of the utility model for solving the technical problem is that: the utility model provides a two-way projection arrangement, includes light emitting module, camera lens, box, light emitting module sets up inside the box, the camera lens is passed to light emitting module's light path, its characterized in that: the camera lens is the nearly burnt camera lens, still includes the far focus camera lens, the far focus camera lens sets up on the lateral wall behind the box, still includes the reflect meter who is used for reflecting the light path of optical emission module to the far focus camera lens, reflect meter sets up inside the box.

The reflecting device comprises a first reflecting plate used for reflecting light emitted by the light emitting module, a second reflecting plate used for reflecting the light reflected by the first reflecting plate to the telephoto lens again, and a rotary fixer used for rotating and fixing the first reflecting plate, wherein the first reflecting plate is rotatably connected with the inside of the box body through the rotary fixer.

in order to conveniently adjust the projection in the positive direction and the negative direction, the projection adjusting device further comprises a P L C and a control panel, wherein the output end of the control panel is connected with the input end of the P L C, and the output end of the P L C is connected with the input end of the rotating fixer.

in order to provide remote operation, the remote control further comprises a remote controller, and an output end of the remote controller is connected with an input end of the PLC.

the beneficial effects of the utility model are that through set up camera lens, reflect meter respectively in positive and negative two directions, reflect the light path, make the projecting apparatus can carry out the projection in positive and negative two directions, see through and set up nearly burnt camera lens in the front, set up far burnt camera lens at the back, satisfied because of the projecting apparatus can't be at the problem of wall formation of image at the single focus camera lens that the distance difference of two walls apart from, through setting up P L C, control panel, remote controller, convenience of customers operates the projecting apparatus.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, 2 and 3, the utility model discloses a light emitting module 1, camera lens, box 3, light emitting module 1 sets up inside box 3, the camera lens is passed to light emitting module 1's light path, its characterized in that: the camera lens is nearly burnt camera lens 2, still includes far focus camera lens 4, far focus camera lens 4 sets up on the lateral wall behind box 3, still includes the reflect meter that is used for reflecting far focus camera lens 4 with the light path of optical emission module 1, reflect meter sets up inside box 3, and the arrow direction in the picture is the direction of light path.

The reflecting device comprises a first reflecting plate 5 used for reflecting light emitted by the light emitting module 1, a second reflecting plate 6 used for reflecting the light reflected by the first reflecting plate 5 to the telephoto lens 4 again, and a rotating fixer 7 used for rotating and fixing the first reflecting plate 5, wherein the first reflecting plate 5 is rotatably connected with the inside of the box body 3 through the rotating fixer 7.

in order to conveniently adjust the projection in the positive direction and the negative direction, the projection adjusting device further comprises a P L C and a control panel, wherein the output end of the control panel is connected with the input end of the P L C, and the output end of the P L C is connected with the input end of the rotating fixer 7.

this device is when using, when needs frontal projection, the same with the projection principle of current projecting apparatus, first reflecting plate 5 is in the horizontality and can not shelter from the light path this moment, when needs back projection, use control panel or remote controller to give an instruction to the P L C, the rotatory fixer 7 of P L C control rotates, drive first reflecting plate 5 clockwise rotation 45 degrees, the light path after being reflected is vertical downwards, at the second reflecting plate 6 through 45 degrees settings to one side, reflect the light path to the horizontal direction backward, jet out through telephoto lens 4.

The front projection uses the near-focus lens 2, so the projector can be close to the television wall in the front projection, the wall distance of the back projection is far at the moment, but the far-focus lens 4 still can form images on the far wall due to the characteristic of the far-focus lens, and the distance between the back wall and the front wall (television wall) in the house is not controllable, so that the far-focus lens 4 can project on the back by using the far-focus lens 4 with proper focal length based on the front projection during the setting.

the projector can project in the front direction and the back direction by respectively arranging the lens and the reflecting device in the front direction and the back direction to reflect the light path, the problem that a single-focus lens cannot image on a wall due to different distances between the projector and two walls is solved by arranging the near-focus lens on the front side and the far-focus lens on the back side, and the projector is convenient for a user to operate by arranging the PLC, the control panel and the remote controller.
