Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figures 1 to 6: present embodiment discloses a kind of electric locking devices: including planetary reduction gear clutch component 2, Interior oscillating arm mechanisms 5, lock tongue 6, lock body 7 and lock 8, planetary reduction gear clutch component 2 include ratchet 21, planetary gear 22 and sun gear 24, planetary gear 22 is engaged with ratchet 21, sun gear 24, power device of the connection of sun gear 24 for driving sun gear to rotate, Planetary gear 22 connects interior oscillating arm mechanisms 5 by planetary wheel carrier 23, and ratchet 21 is also connected with ratchet braking, ratchet braking packet Ratchet 31 is included, lock tongue 6 is connected to lock body 7, is additionally provided between lock tongue 6 and lock body 7 for filling lock tongue 6 far from the elasticity of lock 8 It sets, is additionally provided between sun gear 24 and lock body 7 for making sun gear 24 be only capable of locking the unidirectional device of direction rotation to lock tongue 6.
Specifically, unidirectional device is the unilateral bearing 25 being set between sun gear 24 and lock body 7.
Elastic device is the lock tongue torsional spring 61 being set between lock tongue 6 and lock body 7.One end of lock tongue torsional spring 61 connects lock tongue 6, the other end connects lock body 7.
It is preferred that the ratchet braking of the present embodiment further includes electromagnet 3, and when ratchet 21 is in on-position, electromagnetism Iron 3, which stretches out, pushes ratchet 31 to move, and ratchet 31 is made to implement to brake to ratchet 21.When ratchet 21 is in non-brake state, ratchet 31 separate under the driving of ratchet return mechanism with ratchet 21.
Ratchet return mechanism is the ratchet torsional spring 32 for being set to lock body 7, and ratchet torsional spring 32 is for driving ratchet 31 far from spine Wheel 21 makes ratchet 31 be detached from ratchet 21 when 3 power loss of electromagnet (Fig. 5 state).
The power output end of the preferred decelerating motor 1 of power device of the invention, decelerating motor 1 connects sun gear 24.
The invention also includes travel switches 4, and when interior oscillating arm mechanisms 5 driving lock tongue 6 is connect with lock 8, oscillating arm mechanisms 5 are touched Travel switch 4 is sent out, the signal that locking is completed is fed back to control device by travel switch 4, and control device makes decelerating motor 1 stop turning It is dynamic.
5 connecting pin of interior oscillating arm mechanisms of lock tongue 6 is additionally provided with lock tongue idler wheel 62, lock tongue idler wheel 62 for reducing lock tongue 6 with it is interior Sliding friction is converted rolling friction by frictional force between oscillating arm mechanisms 5.
The present embodiment also discloses a kind of rail vehicle door: electric locking device above-mentioned is equipped with, specifically, lock body 7 connects Integrate with the door leaf of vehicle doorn, and lock 8 is connected to the doorframes of rail vehicle door.
The present embodiment also discloses the working method of above-mentioned electric locking device, makees to illustrate one by one now in conjunction with attached drawing:
When lock operation: electromagnet 3 must be electric, and driving ratchet 31 makes ratchet 21 be in on-position, and decelerating motor 1 drives the sun 24 rotation of wheel, by taking Fig. 2 to Fig. 5 view as an example, sun gear 24 is rotated clockwise according to the view of Fig. 4, due to ratchet 21 at this time In on-position, therefore planetary gear 22 is done clockwise while carrying out rotation counterclockwise around the center of sun gear 24 Revolution then drives planetary wheel carrier 23 and interior oscillating arm mechanisms 5 to rotate clockwise, and interior oscillating arm mechanisms 5 drive the lock tongue idler wheel of lock tongue 6 62 movements are driven 62 opposite end of lock tongue idler wheel of lock tongue 6 and are attached with lock 8, when interior oscillating arm mechanisms 5 contact to travel switch When 4, the signal that locking is completed is fed back to control device by travel switch 4, and control device makes decelerating motor 1 stop operating, at this time Due to being to be connected between sun gear 24 and lock body 7 by unilateral bearing 25, sun gear 24 can not be rotated counterclockwise, therefore even if be subtracted 1 power loss of speed motor will not influence the reliability connected between lock tongue 6 and lock 8.In actual installation process, it can pass through The size of attachment force between lock tongue 6 and lock 8 is realized in the position for adjusting travel switch 4, then realizes and presses between fan door and doorframe The size of power.
It, can since the driving force of decelerating motor 1 is to be transferred to interior oscillating arm mechanisms 5 by planetary reduction gear clutch component 2 To amplify the lesser torque of decelerating motor 1, the decelerating motor 1 of smaller power is made to generate biggish pressure.
When releasing lock operation: 3 power loss of electromagnet, ratchet 31 and ratchet 21 disengage, ratchet 21, planetary gear 22 and planet Wheel carrier 23 is rotatable under the action of external force (driving force of 8 pairs of lock tongues of torsion and lock including interior swing arm torsional spring 51), interior Oscillating arm mechanisms 5 rotate, and lock tongue 6 can be disengaged with lock 8, i.e., openable fan door.
It is total described: when electromagnet 3 has electricity, to be equivalent to 1 input shaft of speed reducer and be in output shaft (interior oscillating arm mechanisms 5) Connection status, in connected state, input shaft are identical as the direction of rotation of output shaft.Furthermore under " connection status ", due to list Effect to bearing 25, input shaft drive output shaft that can only rotate clockwise, that is to say, that decelerating motor 1 can only drive lock tongue 6 With the locking action of lock 8.
When electromagnet power loss, it is equivalent to input shaft and output shaft is in " off-state ", under " off-state ", output Axis can be freely rotated, unrelated with input shaft.
The present invention converts low-speed big power by deceleration device for the small torque power of the high speed of decelerating motor 1, drives Dynamic lock tongue 6 gives the lock 8 being installed on door leaf to pressurize, that is, completes the pressure process of fan door and doorframe.
When lock tongue pressurizes in place, the position of lock tongue 6 should be kept constant, i.e. pressure maintaining period.It should be with machinery under this state Pressure maintaining, decelerating motor 1 powers off, to protect motor.
Due to failure or train arrival, lock tongue 6 should be returned to the state before pressurization, i.e. stress-relief process, stress-relief process should be Automatically unloading, the emergency unlocking function being able to achieve under various failures.It avoids and is driven by electricity release.Because of any one electric appliance member Part is likely to become fault point.When whole power loss of the invention, ratchet 31 can be disengaged with ratchet 21 automatically, and passenger can pass through The occurrence of manually opened fan door avoids emergency power off, and fan door is fail to open.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations Also it should be regarded as protection scope of the present invention.
