Abstract
Unmanned plane launches cabin door switch, is related to unmanned plane.A kind of simple in construction, reliable operation is provided, the unmanned plane for being adapted for carrying out load-carrying airdrop mission launches cabin door switch.Provided with hatch door pin, support, crank, chute, connecting rod and servomechanism；One end of the crank and the bottom of support are connected by rotating shaft, and the middle part of crank is connected by connecting rod with servomechanism, and the other end of crank is provided with chute, and tail end and the chute of hatch door pin are coupled.Servomechanism reception signal, the crank of switching mechanism is driven to rotate and lock, so as to control the opening and closing of hatch door.Servomechanism is only responsible for keeping and breaking poised state of the mechanism at dead point, thus servomechanism work torque is stable near minimum value.Mechanism on crank with hatch door pin contacts uses loading ability of bearing, thus does not produce sliding friction, so switch also can smooth work during heavy－duty.
Description
Technical field
Unmanned plane is the utility model is related to, cabin cabin is launched more particularly, to the unmanned plane for being adapted for carrying out load-carrying airdrop mission
Door switch.
Background technology
In recent years, with the fast development and popularization of unmanned air vehicle technique, the type and function of unmanned plane are increasingly abundanter, adopt
Goods transportation dispensing is carried out with unmanned plane and can be applied to various aspects in life, such as the dispensing of relief goods.In military affairs, it is also possible to
Unmanned plane loads the object with destructive power and target is hit.Therefore, to UAV system freight volume, toter reliability, throwing
Put job stability and smooth requirement also more and more higher.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, reliable operation, is adapted for carrying out load-carrying airdrop mission
Unmanned plane launches cabin door switch.
The utility model is provided with hatch door pin, support, crank, chute, connecting rod and servomechanism；One end of the crank and support
Bottom connected by rotating shaft, the middle part of crank is connected by connecting rod with servomechanism, and the other end of crank is provided with chute, hatch door
The tail end of pin is coupled with chute.
Servomechanism reception signal of the present utility model, the crank of switching mechanism is driven to rotate and lock, so as to control hatch door
Opening and closing.Servomechanism is only responsible for keeping and breaking poised state of the mechanism at dead point, thus servomechanism work torque
Stabilization is near minimum value.Mechanism on crank with hatch door pin contacts uses loading ability of bearing, thus does not produce sliding friction, institute
Also can smooth work with switch during heavy－duty.
The beneficial effects of the utility model are：
1) servomechanism load is small, working stability, corresponding rapid, long lifespan, thus cabin door open and close is smooth, quick, reliability
It is high.Self gravitation opened door is relied on when the gravity of loads is not directly placed on servomechanism and opened the cabin, is suitable for heavy－duty,
And the performance switched will not decline.
2) heavy－duty can be born, dispensing is smooth, and can work long hours.By servomechanism drivening rod control crank with
The relative position of hatch door pin, when crank is vertical with hatch door pin, crank is only by radial load, no rotation trend.Servomechanism is hardly
Stress, thus because of the output torque deficiency of servomechanism hatch door will not be caused surprisingly to open.When opening hatch door, servomechanism is only
Break balance, the driving force then to open a position is provided by tote gravity, and when the thing method of double differences is different big, servomechanism is maintained and broken flat
Power needed for weighing apparatus is all minimum, thus when will not occur general bolt mechanism heavy－duty can not opened door the problem of, servomechanism
Loss is also smaller than common mechanisms.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model embodiment is in closure state.
Fig. 2 is the structural representation that the utility model embodiment is in open stage.
Fig. 3 is the structural representation that the utility model embodiment is in opening stage.
Embodiment
Referring to Fig. 1~3, the utility model embodiment is provided with hatch door pin 1, support 2, crank 3, chute 4, connecting rod 5 and servo
Device 6；One end of the crank 3 is connected with the bottom of support 2 by rotating shaft, and the middle part of crank 3 is connected by connecting rod 5 and servomechanism 6
Connect, the other end of crank 3 is provided with chute 4, and tail end and the chute 4 of hatch door pin 1 are coupled.
Servomechanism reception signal of the present utility model, the crank of switching mechanism is driven to rotate and lock, so as to control hatch door
Opening and closing.Servomechanism is only responsible for keeping and breaking poised state of the mechanism at dead point, thus servomechanism work torque
Stabilization is near minimum value.Mechanism on crank with hatch door pin contacts uses loading ability of bearing, thus does not produce sliding friction, institute
Also can smooth work with switch during heavy－duty.
