Embodiment 1
Refering to Fig. 1, in the present embodiment, a kind of gear-box 10 is proposed.Gear-box includes babinet 11, is provided on babinet 11
Output shaft 421.
As shown in Fig. 2, gear-box 10 further includes the driving gear 100 being set in babinet 11 and driven gear 200.
Wherein, for driving gear 100 for receiving input power, driven gear 200 is used for drive output.
Gear-box 10 can be applied on electronic lock.In the present embodiment, by taking electronic lock as an example, gear-box 10 is done into one
Walk explanation.
Electronic lock can generally be completed to unlock or shut by sending out corresponding instruction using power plant control lock pin
Action.Wherein, lock pin is installed on output terminal.
Power plant can select to use motor 300 for providing input power.Wherein, motor 300 is also disposed on babinet
In 11.
Direct current generator may be used in motor 300.
Electronic lock in some cases, such as without power-off etc., then needs to go to unlock manually.At this point, key can directly be made
For output terminal, control lock pin performs relevant action.Since the power transmission between pitch wheel is reversible, this makes
It obtains in manual actuation output terminal, for output terminal meeting acting in opposition in driving gear 100, driving gear 100 can become load, split
The action locked or shut impacts so that when unlocking or shutting manually, it may appear that the situation of clamping stagnation etc..
To solve such case, rotate be provided with retainer 110 in the present embodiment, on the gear shaft of driving gear 100.
Rotation is provided with the first clutch gear 111 and the second clutch gear 112, the first clutch gear 111 on retainer 110
It is engaged with the second clutch gear 112 with driving gear 100.
When driving gear 100 receives input power, driving gear 100 rotates, due to the first clutch gear 111
It is engaged with the second clutch gear 112 with driving gear 100, the first clutch gear 111 and the second clutch gear 112 can be as planets
It is rotated around driving gear 100, the first clutch gear 111 and the second clutch gear 112 can drive retainer 110 also to turn therewith
It is dynamic.
Wherein, when driving gear 100 receives input power, in the first clutch gear 111 and the second clutch gear 112
One and only one can be in contact with driven gear 200 and engage.
With reference to Fig. 2, the axis parallel of 200 the two of driving gear 100 and driven gear, and it is co-located at a common plane
On.In the present embodiment, the first clutch gear 111 and the second clutch gear 112 are located at the both sides of common plane respectively.
Driving gear 100 and driven gear 200 can according to circumstances use duplicate gear or spur gear.
As shown in figure 3, in the present embodiment, driving gear 100 and driven gear 200 can use duplicate gear.Wherein,
First clutch gear 111 and the second clutch gear 112 are engaged with the small teeth portion of driving gear 100.
Motor 300 provides input power.In the present embodiment, worm screw 310, worm screw 310 are provided in the shaft of motor 300
Intermediate gear 320 is provided between driving gear 100.
Intermediate gear 320 is duplicate gear, including helical teeth portion and straight-tooth portion.Helical teeth portion is engaged with worm screw 310, straight-tooth portion with
The big gearing part engagement of driving gear 100.After motor 300 starts, worm screw 310 and intermediate gear 320 are passed sequentially through by input power
Pass to driving gear 100.
Driving gear 100 drives driven gear 200 to rotate by the first clutch gear 111 or the second clutch gear 112, then
By 200 drive output of driven gear.
In the present embodiment, output terminal includes idle gear 410 and is provided with the output gear 420 of output shaft 421.Idle gear
410 between driven gear 200 and output gear 420, and is meshed with driven gear 200 and output gear 420.Its
In, idle gear 410 can select to use duplicate gear or spur gear.
Output shaft 421 passes through babinet 11, and lock pin can be installed on output shaft 421.
With reference to Fig. 4, after motor 300 starts, when input power drives the driving gear 100 to rotate clockwise, the first clutch
111 and second clutch gear 112 of gear rotates counterclockwise, and retainer 110 rotates clockwise.This causes the first clutch gear
111 can move, while the second clutch gear 112 can be directed away from driven gear 200 towards close to the direction of driven gear 200
Direction is moved, and final first clutch gear 111 can be in contact and engage with the big gearing part of driven gear 200.First clutch gear
111 are always maintained at rotating counterclockwise under the action of driving gear 100, and the first clutch gear 111 is nibbled with the completion of driven gear 200
After conjunction, the first clutch gear 111 driving driven gear 200 rotates clockwise, and is then performed by 200 drive output of driven gear
Corresponding action.
Similarly, when input power driving driving gear 100 rotates counterclockwise, 112 meeting of the second clutch gear and driven tooth
The big gearing part of wheel 200 is in contact engagement so that driven gear 200 rotates counterclockwise.
In the present embodiment, driving gear 100 rotates clockwise corresponding unlocking, rotates counterclockwise correspondence and shuts.At it
It in his specific embodiment, can also be overturned, i.e. the correspondence that rotates clockwise of driving gear 100 is shut, and is rotated counterclockwise pair
It should unlock.
In some cases, it is also necessary to go to complete to unlock or shut manually, if at this point, the first clutch gear 111 or the
Two clutch gears 112 continue the relationship engaged to be kept to talk about with driven gear 200, can increase the load on driven gear 200 so that
The appearance clamping stagnation unlocking or shut is not smooth etc..
For this purpose, in the present embodiment, separation member 113 is additionally provided on retainer 110.Manually when unlocking or shutting, i.e. table
Showing can not be driven using input power, also just illustrate not receive input power on driving gear 100.Separation member 113
Effect is exactly that the retainer 110 is being acted on when driving gear 100 does not receive input power so that the first clutch gear
111 and second clutch gear 112 be not in contact with 200 gear of driven gear.
In this example, separation member 113 has elasticity.
Wherein, separation member 113 can select to use torsional spring.One end of torsional spring is fixedly connected with retainer 110, torsional spring it is another
One end is fixedly connected with babinet 11.Wherein, when driving gear 100 does not receive input power, torsional spring in the raw, this
When retainer 110 be located at initial position, the first clutch gear 111 and the second clutch gear 112 do not connect with driven gear 200
It touches.
After driving gear 100 receives input power, retainer 110 can turn to corresponding position so that the first clutch tooth
111 or second clutch gear 112 of wheel is meshed with driven gear 200, at this point, torsional spring can be because stretching or compressing and generate gesture
Energy.After input power is removed, torsional spring can be restored to nature under the action of potential energy, then drive retainer 110 reversed
Turn to initial position so that be in contact the first clutch gear 111 or the second clutch gear 112 engaged with driven gear 200
It is detached with driven gear 200, at this moment, the first clutch gear 111 and the second clutch gear 112 do not contact with driven gear 200.
In the present embodiment, it is also proposed that a kind of electronic lock, wherein, gear-box 10 is provided on electronic lock.
It will be appreciated by those skilled in the art that the accompanying drawings are only schematic diagrams of a preferred implementation scenario, module in attached drawing or
Flow is not necessarily implemented necessary to the utility model.
It will be appreciated by those skilled in the art that the module in device in implement scene can be described according to implement scene into
Row is distributed in the device of implement scene, can also be carried out respective change and is located at the one or more dresses for being different from this implement scene
In putting.The module of above-mentioned implement scene can be merged into a module, can also be further split into multiple submodule.
Above-described embodiment serial number is for illustration only, does not represent the quality of implement scene.
Disclosed above is only several specific implementation scenes of the utility model, and still, the utility model is not limited to
This, the changes that any person skilled in the art can think of should all fall into the scope of protection of the utility model.
