Embodiment
Embodiment
Referring to Fig. 1 and Fig. 2, it is illustrated that in a kind of cam self-locking gate be a kind of preferred scheme of the present utility model, including
Motor 1, driving gear 2, driven gear 3, closed position sensor 4, gate 5 and open position sensor.Specifically, gate 5
Including gate sheet and swing arm, the swing arm of gate 5 is hingedly mounted on self-service device internal body by gate hinge 51, and gate 5 is whole
Body is freely swung with gate hinge 51 for hinge, realizes opening and closing of the gate sheet to self-service device inner space.
Driven gear 3 is used as a revolving part, by the rolling assembling of rotary gear shaft 32 inside self-service device, rotary gear shaft 32
With the 51 misaligned setting of gate hinge of gate, the swinging plane of the Plane of rotation and gate 5 of driven gear 3 be arranged in parallel,
The Plane of rotation of driven gear 3 is provided with cam path 31, in the control bearing pin of the non-position of articulating point fixed setting protrusion of gate 5
52, cam path of the bearing pin 52 with driven gear 3 will be controlled to slide and be embedded in, the groove width of cam path 31 should be guaranteed that the control energy of bearing pin 52
Enough opposing cam grooves are carried out slidably, drive gate 5 to swing by the cam surface of the two side of cam path 31.
As shown in Fig. 2 cam path 31 is the continuous slideway slided for control bearing pin 52, the slideway is divided into two sections, wherein one
Section is the self-locking section 311 of corresponding closing gate state, and the track of the self-locking section 311 is to be with the rotary gear shaft 32 of driven gear 3
The standard arc section in the center of circle, when gate 5 is closed, the control bearing pin on gate slides into self-locking section 311, and relatively
Cam path forms self-locking；Another section of cam path 31 is the cam segment 312 that corresponding gate realizes opening process and closing process, should
The track of cam segment 312 is the full curve section relative to the radial distance gradual change between the rotary gear shaft 32 of driven gear 3, convex
Section 312 and the continuous transition of self-locking section 311 are taken turns, by the control bearing pin on the change gate of cam segment 312 relative to fixed gear
The distance between rotating shaft, weave control of the gate between opening and closed mode is realized, due to gate opening state not
Need to consider to lock, therefore self-locking section need not be connected in the other end of cam segment 312.
Specifically, in the closed state, the control bearing pin 52 on gate 5 is slided into self-locking section 311, the He of bearing pin 52 is controlled
Line between gate hinge 51 is tangent with any point of self-locking section 311 under closing gate state, in the present embodiment, works as control
When cotter axle 52 moves to the end of self-locking section 311, gate 3 reaches closed mode, now controls bearing pin 52 and gate hinge 51
Line it is vertical with the radial direction of the end of self-locking section 311, now driven gear stall, if swinging lock by applied external force
Door, gate is vertical with the inwall of self-locking section 311 to the active force that opening direction is swung, and self-locking section 311 limits gate in external force
Act on lower swing to open, realize the self-locking of gate 5, while ensure that the driven gear at the place of self-locking section 311 controls in power source
Under can independently rotate.
The gate hinge 51 of the present embodiment is located at the left side of rotary gear shaft 32, and cam segment 312 is arranged to and rotary gear shaft
The distance between diminishing trend, control 3 starting gate 5 of driven gear when, control bearing pin 52 slipped into from self-locking section 311 it is convex
Section 312 is taken turns, the distance of the control opposed gear rotating shaft 32 of bearing pin 52 is gradually reduced, and drives gate 5 to lower swing.
The entire length of the present embodiment convexity race 31 takes 113 ° of the circumference of driven gear 3, the wherein angle of self-locking section 311
Spend for 18 °, the angle of cam segment 312 is 95 °.In practical application, the angle of self-locking section 311 and cam segment 312 is needed according to lock
The angle that door is opened carries out selection design, preferably ensures under closing gate and opening, and control bearing pin 52 is located at certainly respectively
The both side ends for locking section 311 and cam segment 312 are spacing.
Driven gear 3 engages with driving gear 2, forms the output axis connection of speed reducing gear pair, driving gear 2 and motor 1,
The cam path on driven gear is driven to move by motor and speed reducing gear pair.In actual applications, other machineries can be also adopted to pass
Conventional rotary motion transmission mechanism in dynamic is realized, such as chain-drive mechanism, belt gear or frictional wheel drive mechanism.
The closed position sensor 4 of detection gate sheet is set in the both ends extreme position that the gate sheet of gate 5 is swung and opened
Position sensor 6 is opened, when gate swings to the position turned off or on, the position sensor of correspondence position is triggered, transmits position
Confidence number realizes that motor stalls, realizes the closing of gate and open and detect in place to the control circuit of motor 1.On controlling lock
The positive rotaring signal or reverse signal that door is turned on and off then can be supplied to motor by the control system inside self-service device, on
The automatic control technology of self-service device is routine techniques, and the present embodiment will not be described here.
The working condition that the cam self-locking gate of the present embodiment is contrasted below in conjunction with Fig. 3 and Fig. 4 is specifically described.
As shown in figure 3, when gate 5 is closed, gate sheet contacts with closed position sensor 4, now motor 1
Control bearing pin 52 in halted state, gate 5 is located at the end of self-locking section 311, and now gate 5 has the interior of self-locking section 311
Side arc section forms self-locking, and gate 5 can not be opened by applied external force.When self-service device sends the signal of opening gate
When, motor 1 controls driven gear 3 to rotate counterclockwise, and now the self-locking section 311 of driven gear 3 is free relative to control bearing pin 52
Rotate, after controlling bearing pin 52 to slip into cam segment 312 from the abjection of self-locking section 311, turn because cam segment 312 has to gear
The trend that axle 32 moves closer to, now the outside curve of cam segment 312, which pulls, controls 52 downward clockwise oscillation of bearing pin, and then band
The dynamic clockwise oscillation of gate 5 is to opening, and after gate 5 triggers open position sensor 6, controlled motor 1 stalls, this time control
Axle 52 is made and sold as end with cam segment 312, as shown in figure 4, kept it turned on by motor stalling, due to cam can not be anti-
To the characteristic of transmission, gate can remain on.
As shown in figure 4, when gate 5 switches to closed mode by open mode, self-service device sends the letter of closed shutter
Number, motor 1 controls driven gear 3 to rotate clockwise, and now cam segment 312 is changed into the trend being gradually distance to rotary gear shaft 32,
Now the inner side cam surface of cam segment 312 promotes control 52 upward counter-clockwise swing of bearing pin, and then drives the counter-clockwise swing of gate 5
To closed mode, after gate 5 triggers closed position sensor 4, controlled motor 1 is rotated further certain angle, now control pin
Axle 52 enters self-locking section 311 from cam segment 312, and driven gear 3 can be rotated further one relative to gate in place
Determine angle, until stalled after the latching point of control bearing pin 52 end position that slides into self-locking section 311, now gate 5 by
Self-locking section 311 on driven gear keeps self-locking, as shown in Figure 3.
Embodiment above describes the advantages of general principle of the present utility model and principal character and the utility model, one's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate concrete operating principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, this reality
Various changes and modifications are also had with new, these changes and improvements are both fallen within claimed the scope of the utility model, this
Scope is claimed by appended claims and its equivalent thereof in utility model.
