Abstract

The invention relates to a motor-type electronic lock, the main structure comprises a driving motor pivoting a worm portion, a transmission gear set, a linkage gear, at least one elastic component and a bolt body, wherein the linkage gear train comprises a positioning The shaft hole, a sector-shaped rod portion, a connecting portion and at least one abutting portion, and the elastic member comprises a ring portion, a push rod portion and at least one force receiving portion. With the above structure, the worm portion and the transmission gear set are used to change the pushing direction of the driving motor. When the sector-shaped rod portion is driven by the transmission gear set, the interlocking gear shaft rotates with the positioning shaft hole as an axis, and drives the resisting portion to displace, thereby further Pushing the force receiving portion of the elastic member, and finally swinging the push rod portion to drive the bolt body to protrude and engage. Thereby, the overall volume is reduced, and the operating speed of the tongue body is increased.

Description

Motorized electronic lock

The invention provides a motor type electronic lock, in particular to a motor type electronic lock which can eliminate the excess volume of the motor stroke, reduce the overall structure volume, and simultaneously increase the operating speed of the lock.

Press, the lock is mounted on the door panel to lock the door panel, which is a necessary device for indoor security protection. The common lock form is a manual mode operator including a combination of an external lock, an internal lock and a lock bolt, which is often unable to be correctly inserted in a dimly lit place, and is inconvenient due to the time and place.

The automatically controlled motor-type electronic lock, because the stroke of the tongue is electronically controlled, and is a fixed trajectory, without the above-mentioned manual lock problem. When the motor type electronic lock is used for the door lock, it is usually embedded in the door panel, and an opening for the lock tongue is opened at the corresponding lock hole to fix the lock tongue and the lock hole.

However, when the above-mentioned motor-type electronic lock is used, the following problems and defects are indeed to be improved:

First, the power source of the locking tongue for telescopic movement is generally the screw driven by the motor. When the motor rotates, the screw gradually expands and protrudes, and slowly pushes the locking tongue outward. In this push action, it is necessary to provide the space required for the screw extension stroke, so that the space in which the lock specific product can be reduced is limited, but the space usually has no other effect and is very wasteful of space.

Second, the motor of the lock can only push the lock tongue, so it is generally a low-power motor, in other words, its rotation speed is slow, and the pitch of the motor screw used for the small-volume lock is also small, so that the motor needs to be rotated for at least several seconds to complete. The bolt is pushed out so that the unlocking action is very slow.

Therefore, how to solve the above-mentioned problems and deficiencies of the above-mentioned applications is the applicant who is interested in researching and improving the direction of the applicants and related manufacturers engaged in the industry.

Therefore, in view of the above-mentioned deficiencies, the applicant of the present invention collects relevant information, and through multi-party evaluation and consideration, and through years of experience accumulated in the industry, through continuous trial and modification, the design of such a motor-free travel is designed. The invention patented motor-type electronic lock with excess volume, reduced overall structural volume, and improved lock actuation speed.

The main object of the present invention is to change the direction of the force applied by the motor and greatly reduce the volume of space required for the electronic lock.

Another main object of the present invention is to convert the torque of the motor into the power of the bolt body by utilizing the special structure of the transmission gear and the elastic member.

In order to achieve the above object, the structure of the present invention comprises: a driving motor, the driving motor is pivotally provided with a worm portion, and the worm portion is engaged with a transmission gear set, and the transmission gear set is meshed with a linkage gear away from a side of the worm portion The interlocking gear shaft includes a positioning shaft hole, a sector-shaped rod portion formed on one side of the positioning shaft hole, a connecting portion formed on a side of the positioning shaft hole facing away from the sector-shaped rod portion, and at least one formed on the connecting portion a portion of the abutting portion, and a plurality of elastic members are disposed on the shaft of the positioning shaft hole, the elastic member includes a ring portion, a push rod portion formed on one side of the ring portion, and at least a force receiving portion formed on the end of the collar portion facing away from the push rod portion is selectively pushed by the resisting portion, and a locking tongue body is disposed on the side of the interlocking gear, and the push rod portion is Swing selective locking; when the user applies the invention to the electronic lock of the door cabinet, the driving motor is also used to drive the main body of the bolt to engage, but in the process, the worm portion drives the transmission gear set to rotate, thereby driving the fan-shaped rod unit Turning, the interlocking gear rotates with the positioning shaft hole as the axis, and the supporting portion pushes against the force receiving portion of the elastic member, and the elastic member is also pivoted on the shaft by the collar portion, thereby enabling the pushing portion Synchronously swinging to push the bolt body.

With the above technology, it is possible to break through the problems such as excessive volume of the structure of the conventional motor type electronic lock and excess space, and slow movement of the tongue, and the practical progress of the above advantages is achieved.
