Description

Transmission component of an electronic lock

【Technical field】

The utility model relates to a transmission assembly on an electronic lock.

【Background technique】

Existing electronic locks can generally be opened manually and electronically. The electronic opening process is driven by a motor. When the motor is used to drive, when there is an abnormal situation inside the door lock, such as the deadbolt being stuck, the motor will not be able to pass on the operation. , The motor will be stuck until the motor is damaged, which will not only make the motor make abnormal noise but also easily damage the motor, which reduces the quality of the electronic lock and reduces the service life of the electronic lock.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a transmission assembly of an electronic lock that has a simple structure and can prevent the motor from being stuck.

In order to solve the above problems, the utility model adopts the following technical solutions:

A transmission assembly of an electronic lock, characterized in that it comprises

case;

a motor, which is arranged in the housing;

a knob, one end of which is inserted into the housing;

Toggle the wheel, which is plugged into the knob, and the toggle wheel is provided with two elastic toggles and a wheel toggling part that can toggle the touch switch when the toggle wheel rotates ;

The transmission wheel is provided with two toggle protrusions that can respectively toggle the elastic toggle piece to drive the toggle wheel to rotate;

The transmission mechanism is driven by the motor to drive the transmission wheel to rotate.

The transmission assembly of an electronic lock as described above is characterized in that: the toggling wheel is provided with an accommodating groove for accommodating the elastic toggling piece, and the elastic toggling piece protrudes from the the storage tank described above.

The transmission assembly of an electronic lock as described above is characterized in that: the toggle wheel is provided with a slot communicating with the containing groove, the elastic toggle piece is a torsion spring, and the torsion The two ends of the spring are inserted into the slots.

The transmission assembly of an electronic lock as described above is characterized in that: the transmission wheel is provided with a mounting groove, the toggle protrusion is provided on the inner wall of the mounting groove, and the The toggle runner is provided with a mounting boss inserted into the mounting groove, the accommodating groove is arranged on the mounting boss, and the elastic toggle piece protrudes from the mounting boss for The toggle protrusion is squeezed and toggled.

A transmission assembly of an electronic lock as described above is characterized in that: the transmission mechanism includes a worm provided on the motor shaft of the motor and a worm gear meshed with the worm, and the worm gear is provided with There are main transmission teeth, and the transmission wheel is provided with slave transmission teeth meshing with the main transmission teeth.

The beneficial effects of the utility model are as follows: the motor drives the transmission wheel to rotate through the transmission mechanism, and the toggle protrusion on the transmission wheel toggles the elastic toggle piece to make the toggle wheel rotate. When an abnormal situation occurs, the toggle wheel is locked If it cannot be rotated, then when the toggle protrusion toggles the elastic toggle piece, the elastic toggle piece has elastic force and is squeezed down, so that the toggle protrusion rotates over, so that the motor still keeps rotating normally, and the motor shaft does not move. Will be stuck, effectively protect the motor.

【detailed description】

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figures 1 to 6, a transmission assembly of an electronic lock is characterized in that it includes

Housing 1, housing 1 is provided with a hollow cavity, a circuit is provided in the hollow cavity, and two touch switches, the touch switches can control the start and stop or reverse rotation of the motor;

A motor 2, which is arranged in the casing 1;

Knob 3, one end of which is inserted into the housing 1;

The toggle wheel 5 is plugged with the knob 3, and the toggle wheel 5 is provided with two elastic toggle parts 50 and a wheel toggle part 51 that can toggle the touch switch when the toggle wheel 5 rotates , the toggle runner 5 is provided with a housing groove 52 for accommodating the elastic toggle piece 50, the elastic toggle piece 50 stretches out of the accommodation groove 52, and the toggle runner 5 is provided with a plug in communication with the accommodation groove 52. Slot 53, the elastic toggle piece 50 is a torsion spring, the two ends of the torsion spring are inserted into the slot 53, the torsion spring stretches out of the accommodating groove 52, and the two ends of the torsion spring are horizontally inserted into the slot 53, when the torsion spring When the spring received a larger extrusion force, the torsion spring retracted into the containing groove 52;

The transmission wheel 4 is provided with two toggle projections 41 that can respectively toggle the elastic toggle member 50 to drive the toggle runner 5 to rotate. When the toggle runner 5 is not stuck, the transmission wheel 4 can move smoothly. Rotate, at this time, the toggling force of the toggling projection 41 is relatively small, and the torsion spring will not retract into the accommodation groove 52, but is driven to rotate;

The transmission mechanism 6 is driven by the motor 2 to drive the transmission wheel 4 to rotate. The transmission mechanism 6 includes a worm 61 arranged on the motor shaft of the motor 2 and a worm wheel 62 meshed with the worm 61. The worm wheel 62 is provided with a main transmission gear 63, and the transmission wheel 4 is provided with the slave transmission tooth 43 meshing with the main transmission tooth 63.

The transmission wheel 4 is provided with an installation groove 42, the toggle protrusion 41 is located on the inner wall of the installation groove 42, the toggle runner 5 is provided with an installation boss 54 inserted into the installation groove 42, and the accommodation groove 52 Located on the installation boss 54 , the elastic toggle member 50 protrudes from the installation boss 54 for the toggle projection 41 to squeeze and toggle. The inner diameter of the installation groove 42 is greater than the outer diameter of the installation boss 54, and the elastic toggle member 50 blocks the toggle protrusion 41 circumferentially. When the transmission wheel 4 rotates, the toggle protrusion 41 stirs the elastic toggle member 50, so that The moving runner 5 rotates, and when the dead bolt is abnormal, the toggle runner 5 is stuck, and at this moment, the motor 2 will generate a larger rotational force, so that the toggle protrusion 41 will press the elastic toggle member 50, Drive wheel 4 continues to rotate, effectively protects motor like this, prevents motor from being stuck.
