The utility model proposes a kind of cover assembly, it is applied in rpyroelectric infrared sensing device, is covered on the heat
Release outside the pyroelectric sensor of electric infrared sensing device, for the anaclasis on the cover assembly to pyroelectric sensor will to be mapped to
On.
Fig. 1 and Fig. 2 is referred to, in the utility model embodiment, the cover assembly 100 includes annular seating 110 and hood-like
Concentrator 120, the edge of the hood-like concentrator 120 is connected with the upper edge of the annular seating 110；The hood-like concentrator 120
Including lens region 121 and non-lens region 122, the lens region 121 is provided with several single-element lens 123 and (uses the reality with arrow
Line is marked, and is made a distinction with lens region 121), the single-element lens 123 is Fresnel Lenses.
Hood-like concentrator 120 is divided into lens region 121 and non-lens region 122 by technical solutions of the utility model, wherein, it is non-
Lens region 122 is not provided with any optical grains, and lens region 121 is provided with several single-element lens 123, and single-element lens 123 is phenanthrene
Nie Er lens；Because corresponding sensing region can be divided into several area pellucidas and dark space by Fresnel Lenses, make to enter corresponding
The mobile object of sensing region can produce change heat in the form of temperature change on pyroelectric sensor 310 (referring to Fig. 3)
Infrared signal is released, therefore, the only energy of the corresponding sensing region in lens region 121 in the hood-like concentrator 120 of this cover assembly 100
It is enough to be sensed by pyroelectric sensor 310, thus rpyroelectric infrared sensing device 900 using the cover assembly 100 can orient
The sensing corresponding sensing region in lens region 121, without carrying out unnecessary sense to the corresponding non-sensing region in non-lens region 122
Survey, such that it is able to more accurately be oriented sensing to subregion, obtain more accurate sensing result, adapt to hang wall or by wall
The sensing of the electrical equipment of setting needs.
Wherein, the edge of preferably described hood-like concentrator 120 is tightly connected with the upper edge of the annular seating 110, such energy
Enough prevent water, dust etc. from entering in rpyroelectric infrared sensing device 900, so as to extend the rpyroelectric infrared sensing device 900
Service life.In order to reach preferable sealing effectiveness, the hood-like concentrator 120 can be integrally formed with annular seating 110, Ran Hou
The inner side of lens region 121 of hood-like concentrator 120 forms pattern, you can it is saturating to form unit in the lens region 121 of hood-like concentrator 120
Mirror 123.
The effect of lens region 121 is to be focused light, increases the sensing range of pyroelectric sensor 310, while energy
It is enough that sensing region is divided into several area pellucidas and dark space, enable to enter the mobile object of sensing region in the form of temperature change
Change heat is produced to release infrared signal on pyroelectric sensor 310.When the rpyroelectric infrared sensing device using the cover assembly 100
900 when being provided with a pyroelectric sensor 310, and the focus of all of single-element lens 123 is identical, falls the pyroelectric sensor
On 310, so as to the light of all directions is all focused on pyroelectric sensor 310.In order to more accurately carry out subregion positioning,
Rpyroelectric infrared sensing device 900 can set multiple pyroelectric sensors 310 (referring to Fig. 3 to be understood), at this time, it may be necessary to
The lens region 121 is correspondingly arranged multiple lens group, and lens group described in each group includes single-element lens 123 described at least one,
The focus of the single-element lens 123 in lens group described in same group is identical；The focus of one group of single-element lens of lens group 123 falls
Onto a pyroelectric sensor 310, the light that will be mapped on single-element lens 123 is refracted to corresponding pyroelectric sensor 310
In, so sensing region can be carried out subregion, subregion positioning sensing is realized, reach more accurate sensing effect.
Wherein, the position of lens region 121 and non-lens region 122, shapes and sizes need to be chosen according to actual conditions, principle
It is that lens region 121 is according to the sensing region in the front of the electrical equipment hung wall or set by wall and is installed in place rear pyroelectricity and passes
The position of sensor 310 is configured.Further referring to Fig. 1 and Fig. 2, in the present embodiment, preferably described hood-like concentrator 120
Hemispherical setting, the arc that two centers from the hood-like concentrator 120 extend to the edge of hood-like concentrator 120
The hood-like concentrator 120 is divided and forms the lens region 121 and the non-lens region 122.Hood-like concentrator 120 is set
It is hemispherical, sensing angle can be increased；Wherein, each arc is all big by the sphere at the center of hood-like concentrator 120
Round arc so that set in fan-shaped when the lens region 121 and non-122 top view of lens region, so, it is possible to reach more
Uniform refraction effect, it is to avoid the asymmetric situation of sensing region, so as to be more beneficial for accurate sense, in order to adapt to hang wall or lean on
The sensing of the electrical equipment that wall is set is needed, and 180 ° or so of the scope in electrical equipment front is sensed, and is preferably provided with the lens region
121 area is more than the area of the non-lens region 122, and now the corresponding sensing range in lens region 121 can be completely covered electricity
Device front such that it is able to sensed comprehensively.
The light of lens region 121 is mapped to, it is necessary to each position of correspondence sets different lens lines in order to reflect different directions
Road, it is therefore desirable to which several single-element lens 123, the specific distribution situation of those single-element lens 123 are set in the lens region 121
It is configured according to sensing region and the position for being installed in place rear pyroelectric sensor 310, Fig. 2 is referred to, in the present embodiment
In, the lens region 121 is by multiple by the major circle of a sphere at the center of the hood-like concentrator 120 and multiple hood-like poly- with described

The shape of single-element lens 123 described in one is identical with the shape of the correspondence grid.Wherein, the major circle of a sphere is defined as the center of circle on sphere
The circle overlapped with the centre of sphere, the definition of sphere roundlet, can be with by the major circle of a sphere for sphere and by the intersection of the plane of the centre of sphere
Lens region 121 is divided into multiple regions arranged in left-right direction, it corresponds to each position in sensing region horizontal direction
Put, lens region 121 can be divided into by multiple regions arranged along the vertical direction by sphere roundlet, it corresponds to sensing region
Each position on vertical direction, is a defined location of correspondence sensing region at each grid after so dividing, because
, when single-element lens 123 is located in the grid and correspondingly the shape of grid is configured, the light that correspondence position is projected can for this
Accurately it is refracted on pyroelectric sensor 310 by single-element lens 123, it is thus possible to reach very accurate sensing effect.
Lens region 121 needs to allow light to pass through, therefore generally sets the material of the hood-like concentrator 120 for printing opacity is moulded
Material can be specifically the polyolefin plastics such as transparent PE (polyethylene), PP (polypropylene), or increase a little light color (in vain
Color etc.) filler printing opacity but opaque plastics.Certainly, in order to obtain more accurate sensing result, non-lens region can be set
122 is lighttight, so, it is possible further to shield the light that other directions are mapped on hood-like concentrator 120, corresponding pyroelectricity
Infrared sensing device 900 can more accurately be oriented sensing to subregion.
