Description
Technical field
The present invention relates to vehicle, particularly the obstacle detection device on the vehicle.
Background technology
As everyone knows, the quality of driving vision directly has influence on traffic safety.According to statistics, the information of the relevant traffic of driver obtains by vision more than 90%, comprise surface configuration, direction, traffic signals, the content of traffic sign, the residing transport information of vehicle of road, wagon flow of opposite direction etc., above information is easy to obtain by vision by day, but at the night that does not have light, particularly under rugged surroundings, under the situation as interference such as rainy day, greasy weather or flue dust, just difficult relatively.Show according to statistics: traffic hazard takes place be 3 times of daytime night, have the traffic hazard on the road of good lighting condition, just 30% on illumination or the underlit road not.
Though the lamp system of modern vehicle has greatly improved, product is also varied, but can not satisfy driver's requirement, mainly shows: 1, exist the car light irradiation scope little; 2, the penetration power of car light light is poor, under the situation that rainy day, greasy weather or flue dust etc. disturb, makes the driver can better not distinguish road conditions etc.; These also are the important factor in order that traffic hazard takes place.
Summary of the invention
Technical matters to be solved by this invention is: a kind of visible laser detector is provided, it can remedy the deficiency of modern vehicle vehicle light illumination, helps driver's discovery as far as possible early barrier (vehicle, pedestrian at a distance, and then improve traveling security buildings etc.).
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of visible laser detector, it comprises the shell that is fixed on the vehicle, the device that the laser beam that be provided with generating laser in the shell, generating laser is produced scans, shell is provided with the windowpane that penetrates for laser beam.
In the such scheme, the device that the laser beam that generating laser is produced scans comprises two catoptron oscillator unit;
Catoptron oscillator unit comprises catoptron (4), catoptron rotation axis (8), catoptron back-moving spring (7), is arranged on the solenoid (5) in the magnetic field; Fixedly connected with solenoid (5) in the back side of catoptron (4);
The catoptron rotation axis (8) of two catoptron oscillator unit is vertical mutually; The light beam that generating laser (3) penetrates by catoptron (4) reflection of two catoptron oscillator unit, is launched from windowpane (9) successively.
In the such scheme, two catoptron rotation axiss are respectively perpendicular to the magnetic line of force in the solenoid magnetic field of living in of this catoptron oscillator unit; Fixedly connected with the iron core of solenoid in the back side of catoptron.
In the such scheme, two solenoids are in same magnetic field, and two solenoids are respectively vertical solenoid and transverse-electromagnetic coil, fixedly connected with the iron core of transverse-electromagnetic coil, the coil sidewall of vertical solenoid respectively in the back side of two catoptrons.
In the such scheme, magnetic field is produced by the magnet that is provided with in the enclosure.
In the such scheme, the two ends of catoptron rotation axis are connected with outer casing inner wall.
In the such scheme, an end of back-moving spring is connected with solenoid, and the other end is connected with outer casing inner wall.
In the such scheme, the two ends of catoptron rotation axis are connected with outer casing inner wall by supporting.
In the such scheme, an end of back-moving spring is connected with outer casing inner wall by support.
In the such scheme, support is an adjustable support.
The principle of work of visible laser detector of the present invention is:
The laser beam that generating laser in the shell sends, the device that the laser beam that process produces generating laser scans, windowpane from shell is launched, the tiny laser beam of launching runs into distant objects and can reflex in driver's eye, and the driver just can make corresponding reaction according to the detection event of receiving.
The device that the laser beam that generating laser is produced scans comprises catoptron oscillator unit, its principle of work is: when the solenoid of catoptron oscillator unit feeds alternating current, can produce induced field (magnetic direction can be judged by the right-hand rule) with the frequency of electric current, the residing former magnetic field of solenoid is to the acting force (gravitation or repulsion) of induced field, can drive catoptron rotates around catoptron rotation axis moment according to the frequency of alternating current, under the effect of back-moving spring, catoptron can come the back rotation vibration around catoptron rotation axis high-frequency.Because the catoptron rotation axis of two catoptron oscillator unit is vertical mutually, make a catoptron around the vibration of catoptron rotation axis high-frequency lateral rotation, another catoptron vertically rotates vibration around catoptron rotation axis high-frequency.
The laser beam that generating laser in the shell sends, after mirror reflects horizontal, vertically rotation vibration, windowpane from shell is launched, realize the scanning of laser beam in a rectangular area, because catoptron oscillator unit frequency is high, the frequency of laser beam flying also high (selecting the numerical value the same with the frequency of eye-observation things for use) just can be finished the scanning of whole viewing area at 0.3-0.5 in the time of second.
Because the laser beam flying luminous point refreshing frequency that visible laser detector of the present invention is launched is very high, can not cause the sensation of dazzling the eyes to human or animal at a distance, when having guaranteed traveling security, also give " civilization driving " favourable assurance.
Because laser has that monochromaticity is good, good directionality, anti-interference is good, brightness is high characteristics, therefore, the distance (more than 500 meters) of visible laser detector scanning of the present invention, the brightness height, can help driver's discovery as far as possible early barrier (vehicle at a distance, the pedestrian, buildings etc.), and then improve traveling security.
Visible laser detector of the present invention also has the following advantages:
1, the driver can change two catoptron corner sizes by regulating the voltage that feeds electric current, and then regulate the size of the sweep limit of laser beam according to personal habits and needs; Change two catoptrons rotation oscillation frequency by regulating the frequency that feeds electric current, and then regulate the sweep frequency of laser beam.
2, the driver can also regulate the size of the sweep limit of laser beam according to personal habits and needs by the adjustable support of regulating back-moving spring.
Visible laser detector wave beam of the present invention is narrow, volume is little, simple in structure, cost is low, helps large-scale promotion.
