Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
In order to make those skilled in the art more fully understand application scheme, below in conjunction in the embodiment of the present application
Attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is only
The embodiment of the application a part, instead of all the embodiments.Based on the embodiment in the application, ordinary skill people
Member's every other embodiment obtained without making creative work, all should belong to the model of the application protection
It encloses.
It should be noted that the description and claims of this application and term " first " in above-mentioned attached drawing, "
Two " etc. be to be used to distinguish similar objects, without being used to describe a particular order or precedence order.It should be understood that using in this way
Data be interchangeable under appropriate circumstances, so as to embodiments herein described herein.In addition, term " includes " and " tool
Have " and their any deformation, it is intended that cover it is non-exclusive include, for example, containing a series of steps or units
Process, method, device, product or equipment those of are not necessarily limited to be clearly listed step or unit, but may include without clear

The embodiment of the present application.
As shown in Figure 2, a kind of infrared distance measurement radar, including radar ontology 7, further include cleaning apparatus for self, and described is certainly clear
Clean device includes driving device 8, rocker arm 9, rain brush 10, and for driving rocker arm 9, rain brush 10 is arranged on rocker arm 9 driving device 8,
Rain brush 9 is contacted with the window 3 on radar ontology 1 and can be moved on window 3.
Driving device 8 passes through rocker arm 9It drives rain brush 10 round-trip in fixed angle, carries out the bristle of rain brush 10 and window 3
Friction can effectively brush the dust and dirty, easy to operate without manual cleaning, guarantee radar ontology 7 on 3 surface of window
Normal work.
The rocker arm connect or cooperates with driving device, and section is L-type, as needed may be I type.
Rocker arm 9 and driving device 8 are by driving axis connection, and using L-type section, wherein the mono- horizontal window direction L extends, rain
Over an elongate sections, 10 bristle lengths of rain brush are smaller in this case, and brush dust dirt effect is more careful for brush 10.If using I type,
10 length of rain brush is larger, and this rain brush is suitble to biggish window 3.
The rocker arm 9 it is parallel with 3 place face of radar window and driving device 8 driving under back and forth movement.
The angle of 9 back and forth movement of rocker arm, just to enable the scope of activities of rain brush 10 that window 3 is completely covered, and can also
Subject to clearing up to 7 surface of radar ontology.
The driving device 8 is arranged in radar ontology 7 or connect with radar ontology 7.
As shown in Figure 2 and Figure 3, when driving device 8 is arranged in radar ontology 7, entire driving device is included in radar
In body housing, reduce driving device 8 influenced by the external world, inside and outside entire shell dustproof and waterproof grade can reach ip65 and with
On.
As shown in figure 4, driving device 8 is arranged outside radar ontology 7 when driving device 8 is connect with radar ontology 7, this
Kind setting can dismantle, and facilitate maintenance, replace.
The driving device 8 is servo motor, stepper motor or steering engine.
The rain brush 10 is detachable.
Rain brush 10 needs replacing, because being prone to wear so using dismountable mode.
9 material of rocker arm is metal or plastics or ABS alloy, and 10 material of rain brush is silica gel or rubber or EVA foam
Or fiber, 3 shape of window are plane or curved surface, material is glass or plastics.
The selection of 10 material of rain brush is mainly used for that ratio using fiber primarily directed to different environment, such as rain brush
More sticking floating dust；Silica gel or the rubber main distinction are the difference of aging and resisting temperature and the difference of cost；EVA master
If very light floating dust can be used.
As shown in figure 3, the radar ontology 7 includes a control module 11, it to be used for control radar ontology 7, driving device 8
Work.
The control module 11 is used to set the running parameter of driving device 8, so control rain brush 10 times of exercise,
Movement angle, round-trip interval.
The times of exercise of the rain brush 10 is 1-20 times, and movement angle is 0-130 °, is divided into 1300ms- between round-trip
3200ms。
After radar 7 external power supply of ontology, 10 setting in motion of rain brush, back and forth movement is primary, and referred to as primary dedusting operates, fortune
Dynamic angle is that movement angle is 0-130 °, so that the entire motion range of rain brush 10 covers effective ranging window 3 of radar.When
After dust removal operation, radar ontology starts ranging work, and in dust removal operation, radar does not work, and does not export any data.
Describe the technical principle of the application in conjunction with specific embodiments above.These descriptions are intended merely to explain the application's
Principle, and it cannot be construed to the limitation to the application protection scope in any way.Based on the explanation herein, the technology of this field
Personnel do not need to pay for creative labor the other specific embodiments that can associate the application, these modes are fallen within
Within the protection scope of the application.
