Description
Technical field:
The utility model relates to sensing device, particularly a kind of angle level sensor of the vehicles.
Background technology:
The detection of position, angle can be finished with a lot of modes, can be as potentiometer, Hall element, variable condenser, rotary encoder or the like as the sensor that detects the position, angle, these devices have a common type of service: they are to be driven by a link gear, these devices and detected object are rotated synchronously, when rotating, sensor produces the numerical value change of magnetic, electricity, pulse etc.Problem is: 1, and link gear produces the error of precision unavoidably, and degree of accuracy is poor.As detect position, rudder for ship angle and be one and constitute link gear that realistic accuracy is difficult to reach 0.1 degree according to the parallel principle of parallelogram opposite side.2, these devices are not specially for the design of position, angle sensing, and numerical value change linear imperfect influences degree of accuracy.3, zero-bit is adjusted difficulty, and the detection of a class such as the rudder angle of steamer, the direction of automobile are arranged, substantially be not more than 180 degree, but need to determine zero-bit, the existing senser element that is used for the detection of position, angle, all can not 360 except rotary encoder the detections of degree, give the many troubles of definite increase of zero-bit.4, what these devices produced is not direct operable digital code information, is simulation or the pulse signal that needs conversion, the response time that influence is whole.
Summary of the invention:
The purpose of this utility model be invention a kind of indirect that rotate together in company with object to be detected, directly read the passive laser of the indirect type separation type angle level sensor of position, angle change information.
The utility model is achieved in that the passive laser of indirect type separation type angle level sensor is made of a fitting and main body, main body is by the laser recognizer, identification piece, circuit board, web member and shell are formed, the laser recognizer, identification piece, circuit board, the web member sealing in the enclosure, arranging on the identification piece and identifying, sign is the mark that the laser recognizer can be discerned, a mark is represented a numerical value, the laser recognizer can read the sign on the identification piece, the sign that circuit board can read the laser recognizer becomes the format digital code information that can directly use by encoding and decoding and calculating, between fitting constitute by driving link and Passive part, on driving link and the Passive part tooth bar is arranged.
It is characterized in that: identification piece is fixed on the web member, and web member is fixed on the Passive part, and driving link is fixed on the object to be detected, and the laser recognizer is fixed, the reading mouthful facing to the sign on the identification piece of laser recognizer.
Wherein, the length that identifies on the identification piece is greater than the length that reads mouth path of process on identification piece.
Wherein, sign comprises position, angle information and check information.
Wherein, sign has plane mark and three-dimensional sign.
Precision of the present utility model is considerably high, goes for position, various angle and detects the occasion use.
