Abstract
The utility model provides a shell of an anti-interference infrared sensor, which comprises an upper shell and a bottom shell, wherein the upper shell is provided with an upward protruding lens part, a light guide column is arranged in the lens part, a light guide channel is formed in the light guide column, and at least one layer of ladder structure for installing different lenses is arranged in the light guide column, wherein when an infrared light source is installed between the upper shell and the bottom shell, emergent light of the infrared light source is emitted to the outside from the light guide column. When the sensor formed by the shell is used outdoors, sunlight is refracted and diffusely reflected, and then enters the lens part and the inside of the light guide column, and various refraction and reflection and material absorption are carried out on the inner wall of the light guide column, so that the damage of sunlight to elements in the shell can be prevented, and the anti-interference effect is achieved.
Description
Technical Field
The utility model relates to the field of infrared sensors, in particular to a shell of an anti-interference infrared sensor.
Background
The infrared sensor is widely applied to the fields of intelligent manufacturing, robots, safety and the like. The principle of the infrared sensor is that the infrared sensor is split, an infrared light source of the transmitter emits infrared rays at one end, and a receiver is arranged at the other end to receive the infrared rays; the other type is integrated, the emitter and the receiver are integrated on the same circuit board, light rays are diffusely reflected or directly reflected after an infrared light emitting target of the emitter is arranged, the receiver receives the diffusely reflected light rays, and then corresponding calculation judgment is carried out.
The infrared sensor has the use scene including indoor and outdoor, when the infrared sensor is used outdoors, the emitting light source or the receiving light source of the infrared sensor is easy to be interfered by sunlight, and even if the infrared sensor is not under the direct irradiation of the sun, various refracting and diffuse reflection light rays of the sunlight easily enter the sensor to influence the optoelectronic element in the sensor.
Disclosure of Invention
The utility model aims to provide a shell of an anti-interference infrared sensor.
In order to achieve the above purpose, the following technical scheme is adopted:
the utility model provides an anti-interference infrared sensor's casing, includes epitheca and drain pan, the epitheca has upward convex camera lens portion, be provided with the leaded light post in the camera lens portion, lead to in the leaded light post is inside to be formed with the leaded light passageway and have at least one deck ladder structure that is used for installing different lenses, wherein when installing the infrared light source between epitheca and the drain pan, the emergent light of infrared light source is followed in the leaded light post is penetrated outside.
Further, the light guide post, the lens portion and the upper case are integrally formed. Can be formed through one-time injection molding, and is convenient to assemble with the bottom shell, the circuit board and other elements in the follow-up process.
Further, the top of the light guide column extends to be connected with the top of the lens portion, and a gap is formed between the outer wall of the light guide column and the inner wall of the lens portion. Saving the raw materials of the shell to reduce the cost.
By adopting the scheme, the utility model has the beneficial effects that:
based on the convex lens part and the light guide column in the lens part, when the sensor formed by the shell is used outdoors, after sunlight refracts and diffusely reflects light rays enter the lens part and the light guide column, the sunlight can be prevented from damaging elements in the shell through various refraction and reflection and material absorption of the inner wall of the light guide column, and the anti-interference effect is achieved.

Detailed Description
Exemplary embodiments that embody features and advantages of the present utility model will be described in detail in the following description. It will be understood that the utility model is capable of various modifications in various embodiments, all without departing from the scope of the utility model, and that the description and illustrations herein are intended to be by way of illustration only and not to be construed as limiting the utility model.
As shown in fig. 1-2, a housing of an anti-interference infrared sensor includes an upper housing 1 and a bottom housing 2, the upper housing 1 has a lens portion 11 protruding upward, a light guide column 12 is disposed in the lens portion 11, a light guide channel 13 is formed in the light guide column 12, and at least one layer of step structure 14 for mounting different lenses is formed, wherein when an infrared light source is mounted between the upper housing 1 and the bottom housing 2, the emitted light of the infrared light source is emitted to the outside from the light guide column 12. The light guide column 12, the lens portion 11 and the upper shell 1 are integrally formed, specifically may be formed by one-time injection molding, and are convenient to be assembled with the bottom shell 2, the circuit board and other elements in the following steps, the top of the light guide column 12 extends to be connected with the top of the lens portion 11, a gap is formed between the outer wall of the light guide column 12 and the inner wall of the lens portion 11, and raw materials of the shell are saved so as to reduce cost.
The lens part 11 can be provided with other ladder structures 14 at the top for matching with different lenses to play roles of light condensation, light transmission and the like.
The light source element may be mounted between the bottom shell 2 and the upper shell 1, in particular fixed to the bottom shell 2, with its emitting element corresponding to the outlet of the light guide channel 13.
Based on the convex lens part 11 and the light guide column 12 in the lens part 11, when the sensor formed by the shell is used outdoors, after sunlight refracts and diffusely reflects light rays enter the lens part 11 and the light guide column 12, the sunlight can be prevented from damaging elements in the shell through various refraction and reflection and material absorption of the inner wall of the light guide column 12, and the anti-interference effect is achieved.
While the present disclosure has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration rather than of limitation. As the present disclosure may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
