Description
Technical field
The invention belongs to space articulation technical field, specifically, relate to a kind of plane connecting equipment and the electromagnetic self-locking mechanism that are adapted to allosteric type model calling.
Background technology
Existing common connecting device, general existence two kinds of problems: first, if the load that connecting device bears is larger, then need to change the larger actuator of power, such one side improves the cost of connecting device, on the other hand, adopt the actuator that power is larger, also directly can increase the volume and weight that connecting device takies; The second, after most connecting device completes connection task, actuator needs the moment to keep open state to prevent dockingundocking, and energy consumption is very big.
Therefore, in connection task process, there is the problems such as cost is high, weight and volume is large, energy consumption is too many in existing connecting device.
Summary of the invention
The technical issues that need to address of the present invention are: in order to solve existing connecting device to connect in task process the cost existed high, weight and volume is large, the problems such as energy consumption is too many, the present invention proposes a kind of electromagnetic self-locking plane connecting equipment, it can adopt the electromagnetism of smaller power-spring thrust device to meet the demand of bearing compared with heavy load, and (load is born by the elastic force of thruster contained spring, therefore load is determined by the spring selected), can not only reduce costs, also effectively reduce the volume and weight of connecting device, in addition, because the connecting device in the present invention has auto-lock function, so after connecting device completes connection task, actuator can power-off with economize energy, do not worry the problem of dockingundocking after power-off.
Technical scheme of the present invention is: a kind of electromagnetic self-locking plane connecting equipment, is characterized in that, comprises two identical link blocks; Described link block comprises pedestal, handgrip 4, two electromagnetism-spring thrust devices 9, gear 10, sliding rack 6 and tooth bars 7; Pedestal have for the through hole of handgrip 4 motion and the through hole for coordinating with the handgrip 4 of another link block; Two electromagnetism-spring thrust devices 9 are positioned on pedestal and axis is parallel to each other, and its mouth push rod 8 connects tooth bar 7, and tooth bar 7 is positioned on sliding rack 6, and the energising of electromagnetism-spring thrust device 9 and power-off drive two push rods 8 to be with carry-over bar 7 to carry out counter motion respectively; Handgrip 4 one end is connected with gear 10; Tooth bar 7 and gear 10 engage each other, and make handgrip 4 along gear 10 institute in the axial direction, carry out circumferential movement in openings, and the through hole passing another linkage unit synchronously carries out promptly, opening movement.
Further technical scheme of the present invention is: one end that handgrip 4 is not connected with gear 10 is sickle shaped.
Further technical scheme of the present invention is: described through hole is rectangular opening.
Further technical scheme of the present invention is: described handgrip 4 coordinates with gear key.
Invention effect
Technique effect of the present invention is: the present invention is by the break-make of electromagnetism on control mechanism-spring thrust device, the axial motion connecting pawl can be realized, when Liang Ge mechanism is arranged on two carriers simultaneously, can by Liang Ge mechanism to each other arrest the connection realizing two carriers.The connection that implementation space allosteric type intermodule can be assisted autonomous and disconnection.Whole mechanism controls is simple, does not need complicated controller and actuating unit, and under powering-off state, the elastic force still by spring keeps the tension force connecting pawl, saves the energy.

Detailed description of the invention
Below in conjunction with concrete embodiment, technical solution of the present invention is further illustrated.
As accompanying drawing 1-4 shows, the present invention includes and connect plane disc 1, snatch interface 2, handgrip rotates fixing axle bed 3, handgrip 4, slide rail firm banking 5, slide rail 6, the tooth bar 7 that can slide on slide rail, electromagnetism-spring thrust device 9 and push rod 8, the gear 10 coordinated with tooth bar.
Wherein, four identical snatch interfaces 2 are uniformly distributed in and connect plane disc 1 circumference, and namely adjacent snatch interface is separated by angle and is 90 °.Four identical snatch interfaces 2, wherein two interfaces being in relative position (angle of being namely separated by 180 °) are as snatch interface, and two other interface, then for installing handgrip 4.Described handgrip 4 is rotated fixing axle bed 3 by handgrip and fixes, and handgrip only has rotational freedom.Handgrip 4 is coordinated by keyway and gear 10 to be installed.Gear 10 with to be arranged on slide rail 6 slidably tooth bar 7 and to engage; Tooth bar is fixed by slide rail firm banking 5.Slidably tooth bar 7 is fixedly connected with the push rod 8 of electromagnetism-spring thrust device 9.The physical construction that two covers are identical, symmetrical centered by the center of circle connecting plane disc 1.
When being energized to electromagnetism-spring thrust device 9, under the effect of inner electromagnetic attracting force, the push rod 8 of thruster 9 pushes away and stretches out certain length, and the tooth bar 7 promoting to be fixedly connected with it slides a distance on slide rail 6, now, thus rotate with tooth bar 7 gears in mesh 10.Because gear 10 and handgrip 4 coordinate installation by keyway, the moment of rotation is passed to handgrip 4 by gear 10, therefore gear 10 synchronous axial system followed by handgrip 4.Handgrip 4 synchronous axial system of both sides and opening, prepares to have started crawl task.
Connecting device in the present invention, when by electromagnetism-spring thrust device 9 power-off, electromagnetic force disappears because of power-off, but under the restoring force effect of thruster contained spring, push rod 8 automatically restores to the state of contraction, now both sides handgrip 4 synchronous axial system and close button.Therefore do not need to make actuator keep open state, the state of snatch can be kept; And adopt lower-powered actuator also can meet to bear the larger demand of load.
This device comprises two identical link blocks, for convenience connection procedure is described, the first link block and the second link block is called at this, the i.e. handgrip 4 of the first link block, be connected with snatch interface 2 snatch with the second link block, correspondingly, the handgrip 4 of the second link block, is connected with snatch interface 2 snatch of the first link block.
As shown in Figure 1, at initial time, two handgrips are in the state of closing button simultaneously.When the electromagnetism-spring thrust device 9 of the first link block is energized, under the effect of inner electromagnetic attracting force, the push rod 8 of thruster 9 pushes away and stretches out certain length, and the tooth bar 7 promoting to be fixedly connected with it slides a distance on slide rail 6, now, thus rotate with tooth bar 7 gears in mesh 10.Because gear 10 and handgrip 4 coordinate installation by keyway, the moment of rotation is passed to handgrip 4 by gear 10, therefore gear 10 synchronous axial system followed by handgrip 4.Handgrip 4 synchronous axial system of both sides and opening, prepares to have started crawl task.
Be connected with the snatch interface 2 of the second link block at the handgrip 4 of the first link block, after the handgrip 4 of the second link block is connected with the snatch interface 2 of the first link block, by all power-off of this device electromagnetism-spring thrust device 9, internal electrical magnetic force disappears because of power-off, but under the restoring force effect of thruster contained spring, push rod 8 shrinks automatically, now both sides handgrip 4 synchronous axial system and close button, finally return to the state of initial time.Therefore do not need to make actuator keep open state, the state of snatch can be kept; And adopt lower-powered actuator also can meet to bear the larger demand of load, and save the energy widely.
