Abstract
The utility model discloses an electromechanically-operated driving device for lock, with functions of flexible drive and mechanical accumulation energy, and is suitable for the machinery control components in an intelligent lockset, such as a clutch, a locking pin and a latch bolt drove by motor. The utility model comprises a base, a motor fixed on the base, a flexible drive screw, a bracket, an underdriving gear set positioned between the motor and the flexible drive screw, a slidable slider installed on the base, etc. The hollow inner part of the slider is provided with two inward projecting locking pins which is fastened in the mechanical spring helix of the flexible drive screw and pushed fore-and-aft by the rotation of the flexible drive screw. Once the slider is overloaded because of an exterior drag increment, the helical spring on the flexible drive screw can be compressed; when the exterior additional drag disappears, the energy accumulated on the helical spring can be released out to push the slider to move to a precalculated position along straight direction. Simultaneously, the utility model has advantages of simple structure, high reliability, good manufacturability and easy installation.
Description
(1) technical field
The utility model relates to a kind of transmission gear for electric motor of lock, has the function of flexible transmission and mechanical energy storage, is applicable to multiple mechanical controling parts such as motor-driven clutch, bayonet lock and dead bolt in the intelligent lock.Making automatically controlled signal realize being become by rotation the mechanical action of axis direction top offset by this device, is the core controlling organization in the intelligent lock.It not only can control the duty of the functional units such as handle of lockset, can also directly control stretching of dead bolt and change the duty of lockset.
(2) background technology
Automatically controlled execution unit in the intelligent lock except that the scheme that adopts the electromagnet direct pull, adopts micro machine and flexible transmission part to constitute morely at present.The scheme of electromagnet direct pull is because power consumption is big, stroke is short, and reasons such as anti-vibration performance difference are restricted in many application scenarios.And the turning cylinder machining accuracy and the processing request of critical component in the scheme that in the past adopts micro machine and flexible transmission such as screw rod or band bayonet lock are higher, install consuming time more in subminiaturized equipment.
(3) summary of the invention
The utility model has adopted the technology of flexible drive screw, and the lock motor transmission scheme of a kind of processing novelty easy, easy for installation is provided.This scheme not only only can absorb and limit the slider displacement overload on the axis direction of sudden and continuation, and can with drive source the driving energy store in the mode of mechanical energy, in case the slider displacement overload disappears, can be pushed to original preposition by slide block.
The technical scheme that the utility model adopted is:
Whole lock with transmission gear for electric motor by forming with the lower part: base, be fixed on the motor on the base, flexible drive screw and support, the train of reduction gears between motor and flexible drive screw and be installed in slidably slide block on the base.Slide block inside is hollow, is provided with two inwardly outstanding bayonet locks, be stuck between the spring helical of flexible drive screw, and along with the rotation of flexible drive screw by front and back push-and-pull campaign.
Be provided with gathering sill (or guide ridges) and limiting and fixing device between slide block and the base.In order to reduce the sliding friction between slide block and base and the fixture effectively, on the rubbing surface between slide block and the base, slide block and base are provided with or are not provided with outstanding wire or point-like anti-attrition line (point) respectively.
Owing to be that helical by flexible drive screw promotes between power transmission shaft and slide block, there is not the contact of rigidity, therefore belong to a kind of driving of flexibility.In case the resistance accident increase owing to the outside on the slide block causes loading excessive, when surpassing helical spring elastic limit, helical spring on the flexible drive screw will be compressed, when the additional friction of outside disappears, the energy that is accumulated on the helical spring will be released, and promotes slide block and moves to the precalculated position along rectilinear direction.
The beneficial effects of the utility model are:
1. can in the process of transmission, absorb and limit slider displacement overload on the axis direction of sudden and continuation to the influence of drive source.
Can with drive source the driving energy store in the mode of mechanical energy, disappear in case hinder the overload of slider displacement, slide block can be pushed to original preposition.
3. actuating length is big, and moment of torsion and thrust are adjustable, can directly promote the open and close state that dead bolt changes lockset.
4. simple and compact for structure, help reducing the volume of whole transmission gear for electric motor.
5. reliability height, good manufacturability, simple installation is suitable for mass production.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
(5) specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Illustrated is this kind lock with the structure of transmission gear for electric motor, and it comprises flexible drive screw, train of reduction gears (3), slide block (4), the base (5) be made up of power transmission shaft (1) and coiled compression type spring (2), is fixed on the motor parts such as (6) on the base.Motor (6) transmits power on the flexible drive screw by train of reduction gears (3), and when flexible drive screw rotated, the helical on the coiled compression type spring (2) promoted slide block (4) generation and moves forward and backward the bayonet lock effect in the slide block (4).With the flexible drive screw front and back support (7) that base (5) is fixed together, this support plays slide block simultaneously and retreats position-limiting action, and the position-limiting action that the slide block forward direction moves is played in outstanding bayonet lock on the slide block (4) and slider bracket (8) effect.
Design feature:
1. adopt flexible driving screw to realize transmission.
With other patent in the remarkable difference of Flexible Transmission scheme be as Flexible Transmission and energy storage part The spring of part is in rotary state when work.
3. helical spring (2) applies effect by himself helical to the bayonet lock on the slide block (4) and realizes gentle The property transmission. When arriving at the volley front and back limit point (7) (8) or run into, slide block (4) stops volume During outer load, can automatically skid prevents that drive source overload damage and drive disk assembly are locked.
4. flexible driving screw doubles as the energy storage component into this transmission device, and the additional friction when the outside disappears The time, the energy that is accumulated on the helical spring will be released, and promotes slide block (4) along straight line Direction moves to the precalculated position.
5. the maximum driving torque of this transmission device and maximum axial thrust can be passed through adjustable screw spring (2) Rigidity change.
Claims (7)
