Abstract

An electric remote control door lock comprises a door lock mechanism module, a door lock control module and a power module is disclosed in the present invention. The door lock mechanism module comprises a first lock tongue, a second lock tongue, a worm wheel, a worm and a motor. The first lock tongue has a first inclined surface structure, and the second locking tongue has a second inclined surface structure. The worm is driven by the motor, and the worm wheel is driven by the worm. When the worm wheel pushes the first locking tongue, the second inclined surface structure is pushed by the first inclined surface structure, so that the second locking tongue is pushed out. The purpose of simultaneously locking of the first lock tongue and the second lock tongue is then achieved by mutually displaced movement of the first inclined structure and the second inclined surface structure.

Description

Electric remote control door lock

The present invention is a door lock, especially an electric remote control door lock, which can drive a worm and a worm wheel through a motor, and move through the mutual displacement of the inclined structure, so that the first bolt is pushed out while the second bolt is pushed out, reaching two The purpose of locking both bolts at the same time.

The common mechanical locks on the market have complex structures. Any rusty or damaged internal parts will cause unlocking or locking failures. The more complex the structure, the more accidental parts there will be, and the higher the overall failure rate will be, which is likely to cause failure during operation. , And the manufacturing cost and assembly time will also increase.

The existing mechanical lock design usually connects the handle to the tongue. Whether it is a key lock or an electronic lock, the handle is first unlocked and then the handle is turned to unlock the tongue to achieve the purpose of opening the door. The outer door handle becomes the target of thief damage.

Therefore, the inventor has developed a simple and practical electric remote control door lock through long-term thinking, prototype testing and continuous improvement based on relevant practical experience.

The invention provides an electric remote control door lock, which uses a simple inclined surface structure to achieve the purpose of locking the horizontal bolt while the vertical bolt can be simultaneously linked, reducing the internal structure complexity of the door lock and simplifying parts, reducing the overall cost and reducing failures Probability; In addition, because the electric remote control door lock of the present invention and the outer door handle are separated and unlinked, the user can solve the problem through remote control For locks, the outer door handle only provides the function of sliding the door, and the exposed electronic panel or the lock head of the key lock that is not commonly used in electronic locks is used as the target of cracking, so the security can be greatly improved.

In order to solve the aforementioned technical problems, the electric remote control door lock of the present invention includes a door lock mechanism module. The door lock mechanism module includes: a first lock tongue with a first inclined surface structure; a second lock tongue with a second inclined surface Structure, at least a part of the second inclined surface structure of the second tongue is attached to the first inclined surface structure of the first tongue; a worm gear has a gear structure and a first tongue control structure, the first lock tongue The tongue control structure is used to push the first bolt; a worm is used to drive the gear structure of the worm wheel to move the first bolt control structure of the worm wheel; and a motor is connected to the worm to follow a A lock actuation signal or an unlock actuation signal causes the worm to rotate; a door lock control module is used to receive a lock control signal or an unlock control signal, and provide the lock actuation signal or the unlock actuation signal required by the motor ; And a power module used to provide power to the door lock control module.

The worm is driven by the motor, and then the worm is driven by the worm. While the worm gear pushes out the first tongue, the second inclined surface structure is pushed by the first inclined surface structure to push the second tongue out through The mutual displacement of the first inclined surface structure and the second inclined surface structure achieves the purpose of pushing the first tongue and the second tongue to lock at the same time; in addition, it can be seen from the above that the motor drives the first tongue and The second lock tongue only needs to connect the two parts of the worm wheel and the worm, which greatly simplifies the parts and reduces the complexity of the structure; third, it has a double non-reverse structure, the first is the combination of the worm and the worm wheel, and the second The second is that the first bolt manipulation structure pushes against the first bolt.

As an improvement of the present invention, the door lock mechanism module further has a reset mechanism. One end of the reset mechanism is connected to the second bolt, and the other end is connected to the fixed part of the door lock mechanism module. Fixed position, the reset mechanism is spring, hydraulic rod or pneumatic rod. When this structure is adopted, since the return mechanism can strengthen the ability of the second tongue to return to its original position, when in the unlocked state, the kinetic energy of the return mechanism can make the second tongue more accurately return from the locked state Is unlocked.

As another improvement of the present invention, it also includes a touch module, the touch module can provide the lock control signal or the unlock control signal, when the door lock control module detects that the touch module is By touching the locking control signal or the unlocking control signal generated by the touch, the door lock control module makes the door lock mechanism module complete the locking or unlocking action according to the locking control signal or the unlocking control signal. With the above structure, the electric remote control door lock of the present invention can be installed on a door that requires security such as household door locks, vault door locks, etc., and can be unlocked with the touch module wirelessly or arranged inside the door. The door body can be installed with an outer door handle, which only provides the function of a sliding door. The outer door handle does not have any contact or connection with the electric remote control door lock of the present invention, and there is no exposed electronic panel used for electronic locks. The lock head of the keyless lock has no cracking target, which can greatly improve security.

As another improvement of the present invention, it also includes a closure sensing module. When the door lock control module senses a closure signal sent by the closure sensing module, the door lock control module automatically provides the motor The required lock actuation signal. In addition, it can also be set when the door lock control module receives the lock control signal and senses the closing signal sent by the closing sensing module, so that the door lock control module can provide the required motor This lock actuation signal. The closure sensing module can strengthen the control ability of the electric remote control door lock of the present invention to receive the locking actuation signal, and reduce the failure of the door body due to premature driving of the first bolt and the second bolt when the door is closed It is possible to lock; or after the door body is closed, drive the first bolt and the second bolt too slowly, so that others can take advantage of the opportunity to open the door.

In order to make the above and other objects, features and advantages of the present invention more obvious and understandable, Hereinafter, the preferred embodiments will be described in detail in conjunction with the accompanying drawings. However, those with ordinary knowledge in the field of the present invention should be able to understand that these detailed descriptions and specific examples for implementing the present invention are only used to illustrate the present invention, and are not intended to limit the scope of the patent application of the present invention.
