Technical field
The utility model relates to many rotor wing unmanned aerial vehicles, particularly relates to a kind of vibration-proof structure being applicable to many rotor wing unmanned aerial vehicles motor.
Background technology
At present the motor of many rotor wing unmanned aerial vehicles on the market directly and motor fixed arm fix, motor is on-stream can produce dither, dither conducts to body by motor fixed arm, very large impact is caused on the balanced algorithm of the electronic gyroscope in body, electronic gyroscope can be caused time serious to crash, the flying quality of unmanned plane and fail safe are declined greatly.So researching and developing a kind of motor damping mechanism is the technical problem needing in the industry solution badly.
Utility model content
The utility model is the problems referred to above that will solve prior art, proposes a kind of vibration-proof structure being applicable to many rotor wing unmanned aerial vehicles motor.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of motor vibration absorption structure of design, comprise motor and motor fixed arm, and be fixed on the vibration damper plate of motor afterbody, this vibration damper plate periphery offers multiple fixing hole, clamping damping rubber pad in fixing hole, and damping rubber pad stretches out to vibration damper plate two sides through fixing hole, damping rubber pad adopt elastomeric material and in establish through hole, vibration damper plate is fixed on motor fixed arm through through hole by vibration damper plate fixed screw.
The lateral wall of described damping rubber pad is provided with one holddown groove, and holddown groove is stuck in the fixing hole of described vibration damper plate.
Described vibration damper plate is provided with multiple lightening hole in order to weight reduction.
Described motor fixed arm comprises discoidal upper mounted plate and bottom plate, connects the cantilever of upper and lower fixing plate side, and the column between upper and lower fixing plate; Upper and lower fixing plate is fixed with described vibration damper plate and motor respectively.
Fixed plate and bottom plate are provided with multiple lightening hole in order to weight reduction.
The surface of fixed plate and bottom plate is provided with boss on the position of the fixing hole of the described vibration damper plate of correspondence, and boss center is provided with internal thread hole.
Compared with prior art, the utility model utilizes damping rubber pad to carry out damping to the dither that motor produces, and considerably reduces the impact of dither on electronic gyroscope, makes the flying quality of unmanned plane better, also safer.
Accompanying drawing explanation
Fig. 1 is the three-dimensional view of the utility model preferred embodiment;
Fig. 2 is the explosive decomposition view of the utility model preferred embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
The utility model discloses a kind of motor vibration absorption structure, referring to Fig. 1 and Fig. 2, it comprises motor 1 and motor fixed arm, and be fixed on the vibration damper plate 4 of motor afterbody, this vibration damper plate periphery offers multiple fixing hole 7, clamping damping rubber pad 3 in fixing hole, and damping rubber pad stretches out to vibration damper plate two sides through fixing hole, damping rubber pad adopt elastomeric material and in establish through hole, vibration damper plate is fixed on motor fixed arm through through hole by vibration damper plate fixed screw 2.Its essence is and install one piece of vibration damper plate additional in the middle of original motor and motor fixed arm, motor and vibration damper plate through in the through hole precession motor screw hole on vibration damper plate, thus are fixed together by motor fixing screw 5, then are connected with motor fixed arm by vibration damper plate.Be provided with multiple damping rubber pad between vibration damper plate and motor fixed arm, damping rubber pad absorbs the high-frequency vibration having cushioned motor and produced, thus the electronic gyroscope protected in body and other electronic equipment.
Referring to Fig. 2, the lateral wall of described damping rubber pad 3 is provided with one holddown groove 3a, and holddown groove is stuck in the fixing hole 7 of described vibration damper plate, and damping rubber pad two passes fixing hole and stretches out to vibration damper plate two sides.Adopt this structure, vibration damper plate and motor fixed arm and vibration damper plate fixed screw 2 flexibly connect.
Referring to Fig. 2, described vibration damper plate 4 is provided with multiple lightening hole 4a in order to weight reduction.Adopt this structure namely to ensure that the mechanical strength of vibration damper plate, alleviate again the weight of this device.
In many rotor wing unmanned aerial vehicles of some model, lower two motors to be installed on same vertical axis.Referring to the preferred embodiment shown in Fig. 2 and Fig. 1, described motor fixed arm comprises discoidal upper mounted plate 11 and bottom plate 12, connects the cantilever 13 of upper and lower fixing plate side, and the column 14 between upper and lower fixing plate; Upper and lower fixing plate is fixed respectively a set of described vibration damper plate 4 and motor 1.
For weight reduction, fixed plate 11 and bottom plate 12 are provided with multiple lightening hole.
The surface of fixed plate 11 and bottom plate 12 is provided with boss 15 on the position of the fixing hole 7 of the described vibration damper plate of correspondence, and boss center is provided with internal thread hole.Vibration damper plate is fixed on upper mounted plate 11 and bottom plate 12 through the through hole of damping rubber pad 3 by vibration damper plate fixed screw 2.
Above embodiment is only and illustrates, non-ly provides constraints.Anyly do not depart from the application's spirit and category, and to its equivalent modifications of carrying out or change, among the right that all should be contained in the application.
