Embodiment
1st, docking operation
Docking motor 17 is rotated, and the driving gear 18 that drive motor output shaft end is fixed is rotated, and drives driven tooth
Wheel 14 and the feed screw nut 13 fixed therewith by screw-nut are rotated, and trapezoidal screw 16 is extend out to predetermined docking length.Connect
, active mating modules A with it is passive close to each other to connection module B, be oriented to bulb 8 after receiving the conical surface of cone 2 to lead to be slid downwardly into
In portion's cylinder accommodation space until with the front side contact of incline plane of dead bolt 3.Now, due to active mating modules A and passively to connection module B
Still adjacent to each other, and contacted due to being oriented between bulb 8 and the inclined-plane of dead bolt 3 for higher pair, therefore dead bolt 3 contracts under force
Return, back-moving spring 7 is in compressive state, active mating modules A continues close with passive to connection module B.Moved when being oriented to bulb 8
To when receiving 2 cylinder accommodation space top of cone, it is oriented to bulb 8 and is disengaged with dead bolt 3, dead bolt 3 is made in the elastic force of back-moving spring 7
Resetted with lower.Then, docking motor 17 is rotated backward, and trapezoidal screw 16 is retracted to the guiding rear part edge of bulb 8 and dead bolt 3
Rearward plane is in close contact, and now receives cone 2 and the conical surface of guide cone 9 to overlap, and limits active mating modules A and passive docking mould
The one-movement-freedom-degree in tri- directions of block B and pitching and the deflection free degree, now docking operation terminate.
2nd, locking process
After docking operation terminates, locking motor 33 is rotated, 34 turns of the locking worm screw that drive motor output end is fixed
It is dynamic, drive the locking worm gear 35 being engaged with to rotate.Because locking worm gear 35 and active lock gear 39 pass through holding screw
The both sides of active lock gear shaft 30 are fixed on, therefore active lock gear 39 is rotated, and drive the driven locking being engaged with
Gear 38 is rotated.Again due to active lock gear 39 and the gear that driven lock gear 38 is number of teeth modulus all same, therefore two
Person is rotated backward as constant speed, namely driven lock gear axle 31 is rotated backward with active lock gear shaft 30 as constant speed, then is driven
The reverse constant velocity rotation of stay 32 on front side of two axles is individually fixed in predetermined angle, makes stay 32 relative to the outside of steering
Face is with receiving 2 inside grooves upper and lower sides of cone to contact, and the active mating modules A that limitation is only remained is with passive to the relative of connection module B
Rotational freedom, now locking process terminate.
3rd, unlocking process
The process unlocked is the inverse process of locking process, that is, locks motor 33 and rotate backward, drive stay
32 reversion predetermined angles, return to initial position, now unlocking process terminates.
4th, releasing process
After unlocking process terminates, unblock motor 20 is rotated, the unblock worm screw that drive motor output end is fixed
22 rotate, and drive the unblock worm gear 29 being engaged with to rotate.Because unblock worm gear 29 and unblock gear 23 pass through holding screw
The both sides of unblock gear shaft 25 are fixed on, therefore unblock gear 23 is rotated, and drive the unblock rack 24 being engaged with to make straight line
Motion, drives the solution lock collar 19 being fixed with one by screw thread, solution lock collar expansion link 26, unblock rack fixed support 28 sliding
Leading for line slideway 27 is extended downwardly from, until the anterior conical surface and the front side contact of incline plane of dead bolt 3 of solution lock collar 19.Now, due to solution
Lock collar 19 is still being stretched out, and due to being contacted between solution lock collar 19 and the inclined-plane of dead bolt 3 for higher pair, therefore dead bolt 3 under force
Retract, back-moving spring 7 is in compressive state, solution lock collar 19 continues to extend out to be overlapped with being oriented to the trailing flank of bulb 8.Due to solution lock collar
The cylinder changeover portion at 19 middle parts limits the ejection of dead bolt 3, now controls active mating modules A to leave passive to connection module B, then
After the solution cylinder changeover portion of lock collar 19, the preceding surface of dead bolt 3 is with being oriented to the sphere-contact of bulb 8, with modules A and module B
Gradually resetted under relative displacement and the reset response of back-moving spring 7, now, releasing process terminates.
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right
It is required that, in the case of the basic structure without prejudice to the present invention, the present invention can make any type of modification.
