Abstract
The utility model discloses an undercarriage folding and unfolding device for an airplane. The undercarriage folding and unfolding device comprises a control circuit part and a mechanical driving mechanism, wherein the mechanical driving mechanism comprises a motor, a buffer, a piston rod and a connecting component; the control circuit part is provided with a motor control module; the buffer is provided with a laser rangefinder for calculating the height between the airplane and a runway; and the laser rangefinder is connected with the motor control module; and the motor control module controls the folding and unfolding heights of the piston rod by the laser rangefinder. The undercarriage folding and unfolding device disclosed by the utility model has the advantages that the height between the airplane and the runway when the airplane takes off and lands can be calculated by measurement of the laser rangefinder, and the piston rod is controlled by the actual height to adjust the height of wheels, so that the practicability is strong and the promotion value is large.
Description
Technical field
The utility model relates to the undercarriage control device that a kind of aircraft is used.
Background technology
At present, the alighting gear of aircraft is followed the take-off and landing state of different aircrafts and is changed, and wherein the folding structure of the alighting gear of aircraft need to regulate folding and unfolding height according to the distance of real aircraft and runway, and traditional undercarriage tends to because it is improper to regulate, and taking off while landing and the friction of the large resistance of runway, often emerge one blue or green cigarette or print at the runway one section of deep tire that rubs out of friction on runway, causes the serious wearing and tearing of tire.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed the undercarriage control device that a kind of aircraft is used.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: the undercarriage control device that a kind of aircraft is used, comprise control circuit part and mechanical driving mechanism, mechanical driving mechanism comprises motor, energy disperser, piston rod and coupling assembling; Described control circuit partly has motor control module; On described energy disperser, be provided with one for calculating the airborne laser range finder of aircraft and runway height, described airborne laser range finder is connected with motor control module, and described motor control module is by the folding and unfolding height of airborne laser range finder control plunger bar.
Compared with prior art, the airborne laser range finder that the utility model increase to arrange can meter calculate aircraft and runway between distance, and feed back to motor control module, motor control module judges, and by controlling the folding and unfolding height of motor adjusting piston bar, avoid the wearing and tearing of tire when take-off and landing, extended the service life of aircraft tyre.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the undercarriage control device that the aircraft the utility model proposes is used, comprises control circuit part and mechanical driving mechanism, and mechanical driving mechanism comprises motor, energy disperser 1, piston rod 2 and coupling assembling; Control circuit partly has motor control module; On energy disperser 1, be provided with one for calculating the airborne laser range finder 3 of aircraft and runway height, airborne laser range finder 3 is connected with motor control module, and described motor control module is by the folding and unfolding height of airborne laser range finder control plunger bar 2.
In the utility model, airborne laser range finder 3 can meter calculate aircraft and runway between distance, and feed back to motor control module, motor control module carries out discriminatory analysis according to observed reading, and by controlling the folding and unfolding height of motor adjusting piston bar 2, the wearing and tearing of tire when take-off and landing have been avoided.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
