Abstract
The invention discloses a curve antenna array plane pull-out mechanism. The curve antenna array plane pull-out mechanism comprises a shift rod, a hub and a stepping motor, wherein the shift rod is fixedly connected with the hub, the hub is connected with a rotation shaft end of the stepping motor by a speed reduction device and rotates at an uniform speed under the driving of the stepping motor, and baffle rods are arranged on a side edge of an antenna extension arm of a curve antenna array plane at the same distance and matched with the shift rod. The curve antenna array plane pull-out mechanism is simple in design configuration and has good processing technology and assembly process; by the shift rod used with the baffle rods on the antenna extension arm in a matching way, a torque of the motor during rotation is converted to a pull force pulled out of a receiving cylinder from the antenna array plane in a curve state, so that the expansion action of a large-size curve antenna array plane is achieved; and by the targeted design on the height and the number of motor supports, the antenna array plane is enabled to be continuously and stably expanded.
Description
Technical field
The present invention relates to spacecraft structure technical field, specifically a kind of curling antenna array drawing mechanism.
Background technology
To solve the contradiction of spacecraft large area antenna array and delivery envelope size limitation, spacecraft need to be in transmitting actively
Section draws antenna on celestial body in, and working condition is launched and lock onto by antenna after entering the orbit.Particularly, it is rollable for one kind
Antenna array, its emission process curling is drawn in inside admission extinguisher, and in-orbit rear stretching, extension is opened, and a kind of drawing mechanism is needed, to day
Linear array face provides an active force for flexing outward so as to steadily smoothly launch.
The content of the invention
It is an object of the invention to provide a kind of curling antenna array drawing mechanism, is capable of achieving large scale curling antenna array
Expansion action；It is few with parts, light weight, high reliability, and with extensive adaptability.
The purpose of the present invention is achieved through the following technical solutions：One kind curling antenna array drawing mechanism, including driving lever,
Wheel hub and stepper motor, the driving lever is connected with wheel hub, and the wheel hub is connected by decelerator with the rotating shaft end of stepper motor,
Uniform rotation under the drive of stepper motor, installs on the side of the antenna extension arm for crimping antenna array at interval of identical distance
There is a pin matched with the driving lever.
Preferably, also including an electric machine support, the stepper motor is arranged on electric machine support lower end.
Preferably, the design height of the electric machine support and the length of driving lever and quantity need to meet just often save extending arm exhibition
Having driving lever to stir when reaching outlet overcomes the resistance of motion to launch it, so as to ensure that antenna array continuous and stable launches.
Compared with prior art, the invention has the advantages that：
Design configuration is simple, with good processing technology and assembly process process；By on driving lever, with antenna extension arm
Pin be used in combination, what the antenna array that is transformed in rolled state of torque that motor is rotated was extracted out from admission extinguisher
Pulling force, it is achieved thereby that large scale crimps the expansion action of antenna array；Set by the specific aim of electric machine support height and quantity
Meter, so as to ensure that antenna array continuous and stable launches.
Description of the drawings
Fig. 1 is a kind of structural representation of curling antenna array drawing mechanism of the embodiment of the present invention.
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, some deformations and improvement can also be made.These belong to the present invention
Protection domain.
As shown in figure 1, a kind of curling antenna array drawing mechanism is embodiments provided, including driving lever 1, wheel hub 2
With stepper motor 3, the driving lever 1 and wheel hub 2 be connected, and the wheel hub 1 is connected by decelerator with the rotating shaft end of stepper motor 3,
The uniform rotation under the drive of stepper motor 3, at interval of identical distance on the side of the antenna extension arm 4 for crimping antenna array
One pin 5 matched with the driving lever is installed.
Also include an electric machine support 6, the stepper motor 3 is arranged on the lower end of electric machine support 6.
The design height of the electric machine support 6 and the length of driving lever and quantity need to meet just often save extending arm be deployed into out
Having driving lever to stir during mouth overcomes the resistance of motion to launch it, so as to ensure that antenna array continuous and stable launches.
Originally it is embodied as by driving driving lever uniform rotation, the antenna extension of collaboration curling antenna array by stepper motor
Using cooperatively for the pin installed at interval of identical distance on the side of arm, crimps effect of the antenna array in driving lever motive force
Under along slide rail outlet flex outward opening, until being fully deployed to working condition.
The specific embodiment of the present invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can within the scope of the claims make various modifications or modification, this not shadow
Ring the flesh and blood of the present invention.
