Photographic lens

The present invention relates to a photographic lens, and more particularly to a photographic lens having a housing that can be quickly assembled and transformed.

The imaging system is already a common device and is applied to various devices, such as a monitoring device or a car using a camera to capture images for assisting driving. For example, a reversing image system and a lane offset warning system are all installed in the vehicle body. The camera outside the camera captures the image of the outside of the vehicle to assist the driving, but the general camera combination method is to assemble the lens unit first and the image sensing component such as CCD or CMOS and circuit board into semi-finished products, and then assemble the finished product. The semi-finished product is installed in a casing composed of a front cover and a rear cover respectively, and is locked to the casing by a base, so that a plurality of parts need to be assembled when assembling the camera, which not only increases the complexity of assembly but also increases the complexity of assembly. Increase the existence of assembly tolerances. In addition, when the photographic module fails and needs to be disassembled, it is often necessary to disassemble the entire camera from the automobile body, thereby increasing the difficulty of assembly and disassembly.

An image forming unit 30, the image forming unit 30 includes an image sensing component 31, a circuit board unit 32, and a transmission line 33. The transmission line 33 has a line block 331 having a plurality of bumps 332 on the surface thereof. The forming unit 30 is disposed in the accommodating space 12 of the housing 10 for converting the light transmitted through the lens unit 20 into a current output, and the circuit board unit 32 is electrically connected to the image sensing element 31 for the image sensing element. The current formed by 31 is output to an image processing unit (not shown) to form an image to be output via the transmission line 33.

An outer cover 40 has a receiving portion 41 and a plurality of clamping portions 42. The clamping portion 42 has a latch 43 on one side thereof and a hook portion 44 at the rear end of the clamping portion 42 .

A rear cover 50 has a through opening 51 having a plurality of grooves 511 and a plurality of ears 52 at the periphery of the opening 51.

When the photographic lens 1 is assembled, the lens unit 20 is mounted on the housing portion 11 of the housing 10 and protrudes from the housing 10; the image forming unit 30 is mounted in the accommodating space 12 of the housing 10, and the image forming unit 30 is mounted. The sensing element 31 faces the lens unit 20. When the light source passes through the lens unit 20 and enters the accommodating space 12 of the housing 10, the image sensing element 31 of the image forming unit 30 converts the light into a current through an image processing element (not Form) After the image is output, the image is output via the circuit board unit 32 and the transmission line 33; the outer cover 40 and the housing 10 are hooked to the opening 13 of the housing 10 by the hook portion 44 at the end of the clamping portion 42 of the outer cover 40, so that the outer cover 40 is The housing 10 is hooked, and the latch 43 of the clamping portion 42 of the outer cover 40 is engaged with the groove 14 of the housing to make the housing 10 and the outer cover 40 more closely coupled; the rear cover 50 and the housing The openings of the video forming unit 30 pass through the opening 51 of the rear cover 50, and the line 331 on the transmission line 33 is in the shape of a fitting opening 51.

When the transmission line 33 passes through the opening 51, the line 331 is rotated by an angle, and the protrusion 332 of the transmission line is interlaced with the groove 511 of the back cover 50 to achieve mutual integration; When it is required to additionally engage the external support, the ear portion 52 of the back cover 50 can be combined with the external object.

The outer cover 40 can also be assembled on other objects first. When the housing 10 is combined with the lens unit 20 and the rear cover 50, the outer cover 40 can be combined with the outer cover 40, thereby saving installation time and improving installation accuracy.
