Abstract

The utility model relates to a motor driven clutch device with an electric control lock, the structure thereof comprises a motor, a gear drive device and a worm and gear drive device; the upper end and the lower end of a base frame of a motor gear are respectively provided with the motor which is connected with the two ends of a worm shaft core in the worm and gear drive device by the gear drive device; the worm and gear drive device also comprises a worm wheel and a worm, wherein, the worm which is sheathed on the worm shaft core is engaged with the worm wheel arranged on the worm shaft core; the worm can rotate with the worm shaft core and also move freely and radially on the worm shaft core; an upper pressure spring and a lower pressure spring are sheathed on the worm shaft core at the two sides of the worm. The motor driven clutch device with the electric control lock not only overcomes the shortages of insufficient drive power, large power consumption and bad working reliability existing in the traditional electromagnetic type electronic door lock, but also solves the problem that the motor is easily damaged as a lock tongue is locked by the motor-typed electronic door lock, thus greatly improving the stability and duration of lock.

Description

A kind of electric control lock motor-driven arrangement of clutch

Technical field

The utility model relates to a kind of electric control lock motor driver, specifically a kind of electric control lock motor-driven arrangement of clutch with cushioning effect.

Background technology

Existing electronic lock adopts Electromagnetic Drive and motor to drive two kinds mostly: there are shortcomings such as power consumption is big, power is low in Electromagnetic Drive; Often motor is stuck can not to rotate motor-driven owing to reasons such as mechanical outside make, and is directed at the easy scaling loss of motor, directly influences the application life of electric lockset.

The utility model content

Technical assignment of the present utility model is at above weak point, providing is a kind of electric control lock motor-driven arrangement of clutch, setting by compression spring and following stage clip, make worm screw can reliably be connected cushioning effect is arranged simultaneously with worm screw, be difficult for the kayser tongue, no matter motor rotates and reverse, and stability and reliability are all very good.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric control lock motor-driven arrangement of clutch, its structure comprises motor, gear drive, worm gearing, motor is equipped with at two ends up and down at the motor gear underframe respectively, motor then is connected with worm gearing by gear drive, wherein gear drive is made up of motor driving gear and motor driven gear, the motor driving gear is connected with the output shaft of motor, after two gears engaged, the motor driven gear is connected the worm shaft core two ends in the worm gearing, worm gearing also comprises worm gear and worm screw, the worm screw that wherein places the worm gear on the worm-wheel shaft core and be enclosed within on the worm shaft core is meshing with each other, worm screw can follow the worm shaft core to rotate, can on the worm shaft core, radially move freely again simultaneously, worm shaft core two ends place in the bearing, are with compression spring and following stage clip on the worm shaft core between worm screw and the bearing.

Described gear drive and motor output shaft end arranged outside have motor gear frame cover plate.

The electronic lock that a kind of electric control lock motor-driven of the utility model arrangement of clutch both can solve the powered magnetic-type exists shortcomings such as driving force deficiency, power consumption are big, functional reliability difference; The electronic lock that can solve electric motor type again is owing to blocking the problem that dead bolt is directed at the as easy as rolling off a log damage of motor, thereby increases substantially stability, the durability of lockset.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Accompanying drawing 1 is a kind of electric control lock motor-driven arrangement of clutch structural representation;

Accompanying drawing 2 for a kind of electric control lock motor-driven arrangement of clutch remove motor gear frame cover plate the time worm gear just changeing structural representation after stressed;

Accompanying drawing 3 for a kind of electric control lock motor-driven arrangement of clutch remove motor gear frame cover plate the time the structural representation of worm gear counter-rotating after stressed.

The specific embodiment

Explain below with reference to Figure of description a kind of electric control lock motor-driven arrangement of clutch of the present utility model being done.

A kind of electric control lock motor-driven arrangement of clutch of the present utility model, its structure comprises motor 3, gear drive, worm gearing, motor 3 is equipped with at two ends up and down at motor gear underframe 6 respectively, 3 in motor is connected with worm gearing by gear drive, wherein gear drive is made up of motor driving gear 12 and motor driven gear 4, motor driving gear 12 is connected with the output shaft of motor 3, after two gears engaged, motor driven gear 4 is connected worm shaft core 8 two ends in the worm gearing, worm gearing also comprises worm gear 1 and worm screw 9, wherein place worm gear 1 on the worm-wheel shaft core 11 and the worm screw 9 that is enclosed within on the worm shaft core 8 to be meshing with each other, worm screw 9 can follow worm shaft core 8 to rotate, can on worm shaft core 8, radially move freely again simultaneously, worm shaft core 8 two ends place in the bearing 5, are with compression spring 7 and following stage clip 10 on the worm shaft core 8 between worm screw 9 and the bearing 5; Described gear drive and motor output shaft end arranged outside have motor gear frame cover plate 2.
