The inputting module receives image data and sends the image data to the processor. The processor creates instructions according to the image data. The projector lens assembly projects an image which reflects the image data, according to the instructions.

Description

BACKGROUND

1. Technical Field

The present disclosure relates to a projector.

2. Description of Related Art

Projectors, such as digital projectors, have become more versatile and can project images onto almost any nearby flat surface. However, although a variety of surfaces may be suitably used as projection surface, configurations of those projectors still require that the projector be arranged to directly point at the projection surface and to be within a certain distance of the surface, which is inconvenient in many circumstances.

DETAILED DESCRIPTION

Referring to FIG. 1, an embodiment of a projector includes a projector body 10, a mount 20, and a projector lens assembly 30.

An annular positioning portion 11 is centrally fixed on a top of the projector body 10. A through hole 12 is defined in the top of the projector body 10 aligned in the center of the positioning portion 11.

The mount 20 includes a columnar supporting member 21 and a T-shaped connection member 23. The supporting member 21 includes opposite tabs 212 extending up from a top of the supporting member 21. Each of the tabs 212 defines a fixing hole 213. The supporting member 21 axially defines a receiving hole 214 extending through the top of the supporting member 21. The connection member 23 includes a first connection pole 231 and a second connection pole 233 perpendicularly extending down from a middle of the first connection pole 231. The connection member 23 defines a receiving hole 235 along an axis of the second connection pole 233 and extending through the first and second connection poles 231 and 233.

The projector lens assembly 30 includes a columnar main body 31 and a linking member 33. The linking member 33 includes a pivotal portion 332 defining a C-shaped cross section and a shaft 331 connected between a middle of the pivotal portion 332 opposite to an opening of the pivotal portion 332 and a side of the main body 31. An interference-avoiding notch 3321 is defined in a side of the pivotal portion 332, aligned with the shaft 331, and adjacent to the opening of the pivotal portion. The projector lens assembly 30 defines a receiving hole 335 extending along an axis of the shaft 331, the receiving hole 335 extending through the side of the main body 31, the shaft 331, and the pivotal portion 332.

Referring to FIG. 3, an inputting module 101 and a processor 102 are arranged in the projector body 10. A light source 103, a light engine 104, and a lens 105 are arranged in the projector lens assembly 30. In use, the inputting module 101 receives image data and transfers the image data to the processor 102. The processor 102 creates instructions according to the image data and transfers the instructions to the light engine 104. The light engine 104 executes the instructions to form an image, which reflects the image data, using light from the light source 103, and projects the image through the lens 105.

Referring to FIG. 2, in assembly, a lower portion of the supporting member 21 of the mount 20 is received in the positioning portion 11. The receiving hole 214 of the supporting member 21 is aligned with the through hole 12 of the projector body 10. The connection member 23 is secured to the top of the supporting member 21, with opposite ends of the first connection pole 231 respectively fixed in the fixing hole 213 of the two tabs 212, and the second connection pole 233 fixed in the receiving hole 214. The pivotable portion 332 of the projector lens assembly 30 is rotatably sleeved on the first connection pole 231 to rotatably connect the projector lens assembly 30 to the projector body 10 through the mount 20. The second connection pole 233 is adapted to be engaged in the interference-avoiding notch 3321 to prevent the second connection pole 233 from interfering with the pivotal portion 332 in rotation. The receiving hole 335 of the projector lens assembly 30 is aligned with the receiving hole 235 of the connection member 23 to enable a cable 40 connected between the projector body 10 and the projector lens assembly 30 to extend through the receiving holes 335, 235, and 214, and the through hole 12 of the projector body 10. The projector lens assembly 30 can be positioned at a desired projection angle due to a friction force between the pivotal portion 332 and the first connection pole 231.

It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
