Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to an electronic lock. Background Art

[0002] The electric drive opening and closing method of the electronic locks currently on the market is: the transmission shaft is driven by the internal motor to rotate forward or reverse to drive the transmission member on the lock body mechanism to rotate, so that the lock tongue of the lock body mechanism can be driven by the transmission member to perform a telescopic action to switch between unlocking and locking. When the existing lock is installed on a left-opening door, the installation position of the lock is close to the right side of the door body when viewed from the outside of the door, and the telescopic direction of the lock tongue of the lock body mechanism is set toward the right side of the door body; when the lock is installed on a right-opening door, the installation position of the lock is close to the left side of the door body when viewed from the outside of the door, and the telescopic direction of the lock tongue of the lock body mechanism is set toward the left side of the door body; this results in the existing electronic locks needing to be installed in different ways depending on whether it is used for a left-opening door or a right-opening door. If the installer uses the wrong installation method during installation, the electric opening and closing function of the lock cannot be used normally, which is very inconvenient to install. In addition, in order to improve reliability, existing electronic locks retain the use of manual opening and closing. When the existing electronic locks are manually opened and closed, the transmission shaft needs to overcome the resistance of the motor before it can rotate, so that a large force needs to be applied when manually opening and closing the lock, which is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to provide an electronic lock. No matter whether the electronic lock is set on a left-opening door or a right-opening door, the control mechanism has only one assembly method. The uniqueness of the assembly method can effectively prevent the control mechanism from being operated incorrectly during installation and affecting the normal use of the electronic lock. The installation is more convenient, the resistance encountered when manually opening and closing the lock is small, and the use is more convenient.

[0004] The technical solution adopted by the utility model to solve the technical problem is: an electronic lock, including a lock body mechanism and a control mechanism; the lock body mechanism is provided with a lock tongue capable of retracting and a transmission member rotatably connected, the transmission member is rotatably connected to the lock tongue, the transmission member can drive the lock tongue to extend by forward rotation, and the transmission member can drive the lock tongue to retract by reverse rotation, so that the lock body mechanism can switch between a locked state in which the lock tongue is extended and an unlocked state in which the lock tongue is retracted by rotating the transmission member;

[0005] The control mechanism includes a transmission shaft, an outer door manual operation piece, an inner door manual operation piece, a driving shaft, a driven shaft, a driver, a left opening reset position sensor, a right opening reset position sensor and a control module;

[0006] One end of the transmission shaft is connected to the manual operating member outside the door, and the other end of the transmission shaft is connected to the manual operating member inside the door. The transmission shaft is in transmission connection with the transmission member on the lock body mechanism, and the transmission shaft can rotate around its own axis to drive the transmission member to rotate;

[0007] The driven shaft is formed with a driven shaft hole communicating with both ends thereof, the driven shaft is sleeved on the transmission shaft through the driven shaft hole and fixed coaxially with the transmission shaft, a movable slide is formed on the driven shaft, the travel path of the movable slide is arranged around the rotation axis of the transmission shaft, one end of the movable slide is a first transmission end, and the other end of the movable slide is a second transmission end;

[0008] The left opening and resetting in place sensor and the right opening and resetting in place sensor are arranged in sequence around the axis of the transmission shaft;

[0009] A driving shaft hole connecting the two ends is formed on the driving shaft, and the driving shaft is rotatably mounted on the transmission shaft through the driving shaft hole. A transmission convex portion and a trigger convex portion are formed on the driving shaft, and the transmission convex portion can be slidably embedded in the movable slideway of the driven shaft, so that when the transmission shaft is driven to rotate by the hand operating member outside the door or the hand operating member inside the door, the driving shaft and the driven shaft are separated from each other; the trigger convex portion can be driven by the driving shaft to move so that the left opening reset position sensor or the right opening reset position sensor is triggered; in the initial state: the transmission convex portion is arranged close to the first transmission end / the second transmission end, and the trigger convex portion is at a position to trigger the left opening reset position sensor / the right opening reset position sensor;

[0010] The driver is in driving connection with the driving shaft, so that the driving shaft can be driven to rotate by the driver;

[0011] The control module is electrically connected to the driver, the left-opening reset-in-place sensor, and the right-opening reset-in-place sensor. The control module is provided with a status self-detection program, a left-opening control program, and a right-opening control program. The status self-detection program is used to detect whether the electronic lock is set to a left-opening door or a right-opening door. When the electronic lock is set to a left-opening door, the control module starts the left-opening control program to control the operation of the driver. When the electronic lock is set to a right-opening door, the control module starts the right-opening control program to control the operation of the driver.

[0012] The working principle of this utility model:

[0013] The control mechanism of the electronic lock can be preset to the left-opening mode or the right-opening mode at the factory; when the control mechanism is in the initial state of the left-opening mode, the triggering protrusion of the active shaft is in the triggering position of the left-opening reset position sensor, and the transmission protrusion of the active shaft is close to the first transmission end of the movable slideway of the driven shaft; when the control mechanism is in the initial state of the right-opening mode, the triggering protrusion of the active shaft is in the triggering position of the right-opening reset position sensor, and the transmission protrusion of the active shaft is close to the second transmission end of the movable slideway of the driven shaft. When the lock body mechanism is installed, the extension direction of the lock tongue is adjusted by switching the installation mode of the left-opening door and the installation mode of the right-opening door by flipping 180° vertically. Therefore, when the mode state of the control mechanism matches the installation state of the lock body mechanism: when the electronic lock is set to the left-opening door, the forward rotation direction of the transmission member is the same as the forward rotation direction of the transmission shaft; when the electronic lock is set to the right-opening door, the forward rotation direction of the transmission member is opposite to the forward rotation direction of the transmission shaft.

[0014] During installation, the lock mechanism is in unlocked state. After the lock mechanism and the control mechanism are installed on the door body and the control mechanism is powered on, the control module starts the self-detection program. The control module determines whether the control mechanism is currently in left-open mode or right-open mode according to the trigger signals of the left-open reset position sensor and the right-open reset position sensor.

[0015] The following example takes the initial setting state of the control mechanism as the left-open mode as an example:

[0016] The driver applies a positive rotational motion tendency to the driving shaft, so that the transmission convex portion of the driving shaft abuts against the first transmission end of the movable slideway to give the driven shaft a positive rotational motion tendency;

[0017] If the driven shaft can be driven by the driving shaft to rotate forward, the transmission shaft coaxially fixed with the driven shaft drives the transmission member to rotate forward and drives the lock tongue to extend. During this period, the trigger convex part of the driving shaft is driven to move and stops triggering the left-open reset position sensor. The control module can thus know that the mode state of the control mechanism matches the installation state of the lock body mechanism, and then know that the electronic lock is installed on the left-open door. Then, the control module controls the driver to drive the control mechanism to reset to the initial state of the left-open mode, and resets the lock body mechanism to the unlocked state. The control module starts the left-open control program and enters standby.

[0018] If the driven shaft cannot be driven by the driving shaft to rotate in the forward direction, the trigger convex part of the driving shaft will continue to trigger the left-open reset position sensor, and the control module can know that the mode state of the control mechanism does not match the installation state of the lock body mechanism, and then know that the electronic lock is installed on the right-opening door. The control module controls the driver to drive the driving shaft to rotate in the opposite direction, so that the trigger convex part of the driving shaft moves to the trigger position of the right-open reset position sensor, and the transmission convex part of the driving shaft moves from the position close to the first transmission end along the movable slide to the position close to the second transmission end, so that the control mechanism switches to the right-opening mode. Optionally: the driver continues to drive the active shaft to rotate in the opposite direction, so that the transmission convex part of the active shaft abuts against the second transmission end and pushes the driven shaft to rotate in the opposite direction, and the transmission shaft fixed coaxially with the driven shaft drives the transmission member to rotate forward and drives the lock tongue to extend. During this period, the trigger convex part of the active shaft is driven to move and stops triggering the right opening reset position sensor. The control module can thus know that the mode state of the control mechanism matches the installation state of the lock body mechanism; the control module controls the driver to drive the control mechanism to reset to the initial state of the right opening mode, and resets the lock body mechanism to the unlocking state; through the above optional steps, whether the electronic lock is set to open the door on the left or the right, the lock tongue of the lock mechanism needs to complete an unlocking and locking action, so that the installer can easily confirm that the electronic lock can work normally after the electronic lock is installed. Finally, the control module starts the right opening control program and enters standby.

[0019] Through the above design, no matter the electronic lock is set on the left or right door, the control mechanism has only one assembly method. The uniqueness of the assembly method can effectively prevent the control mechanism from making incorrect operations during installation and affecting the normal use of the electronic lock, making the installation more convenient.

[0020] The unlocking and closing steps of the electronic lock when in use are shown in Table 1 below. By cooperating between the transmission convex portion of the active shaft and the movable slideway of the driven shaft, the active shaft and the driven shaft can be separated from each other when the transmission shaft is driven to rotate by the manual operating member outside the door or the manual operating member inside the door. This avoids the need to overcome the resistance of the driver to drive the transmission shaft to rotate when manually unlocking and closing the electronic lock, reduces the force required for manual unlocking and closing, and is more convenient to use.

By cooperating and installing the card-mounted slide groove 7012 and the card-mounted slider 43, the transmission shaft 2 can be coaxially rotatably connected to the driven shaft 4; by clamping the driven shaft 4 and the driving shaft 3 between the retaining spring 6 and the positioning boss 7014, the structure of the control mechanism can be made more compact and the space occupied by the control mechanism inside the door body can be reduced.

With such a structure, the driving shaft 3 and the transmission shaft 2 are not in direct contact with each other and are connected through the bearing 7, thereby reducing the friction between the driving shaft 3 and the transmission shaft 2, and ensuring that the driving shaft 3 can only drive the transmission shaft 2 to rotate by driving the driven shaft 4 to rotate. By setting the first groove 341 through the first step groove 34 and the second groove 7015 through the positioning boss 7014, on the one hand, the contact area between the first step groove 34 and the bearing 7, between the positioning boss 7014 and the bearing 7 can be reduced, and the friction between the first step groove 34 and the bearing 7, between the positioning boss 7014 and the bearing 7 can be reduced; on the other hand, the first groove 341 can provide a certain deformation accommodating space 801 for the inner wall of the first step groove 34, and the second groove 7015 can provide a certain deformation accommodating space 801 for the inner wall of the positioning boss 7014, which is conducive to the assembly of the bearing 7 in an interference fit manner and is more convenient to install.

By adding the unlock monitoring sensor 20, the left door lock monitoring sensor 30 and the right door lock monitoring sensor 40, the control module 50 can more accurately control the driver 5 to drive the lock body mechanism 1 to switch between the unlocked state and the locked state, thereby improving the operation accuracy of the electronic lock, so as to prevent the motor 51 from being in the working state after the lock body mechanism 1 performs the locking and locking actions, thereby protecting the motor 51.

[0067] like Figure 2 , Figure 4 , Figure 5 and Fig.15As shown, the control mechanism also includes a shell 80, one side of the shell 80 is an operating surface, and the other side of the shell 80 is a mounting surface. The mounting surface of the shell 80 is concave to form an accommodating space 801, and the active shaft 3, the driven shaft 4, the driver 5, the left-open reset position sensor 8, the right-open reset position sensor 9, the unlocking monitoring sensor 20, the left-open door locking monitoring sensor 30, the right-open door locking monitoring sensor 40, and the control module 50 are all in the accommodating space 801, and the left-open reset position sensor 8 and the right-open reset position sensor 9 are both arranged on the inner wall of the shell 80 through a mounting seat 10, and the unlocking monitoring sensor 20, the left-open door locking monitoring sensor 30, and the right-open door locking monitoring sensor 40 are arranged on the control module 50; the operating surface of the shell 80 is formed with a accommodating space 801.

By assembling the limiting protrusion 7022 and the limiting slide 804 together, on the one hand, the rotatable range of the manual operation piece 70 inside the door can be limited. The rotatable angle of the manual operation piece 70 inside the door in this embodiment is 180°. On the other hand, such a design can make there be only one installation method between the manual operation piece 70 inside the door and the outer shell 80, so as to determine the installation direction of the manual operation piece 70 inside the door, prevent errors in the installation of the manual operation piece 70 inside the door, and improve the error-proofing of the installation of the electronic lock.

[0068] The working principle of this embodiment:

[0069] The control mechanism of the electronic lock can be preset to a left-opening mode or a right-opening mode at the factory; when the control mechanism is in the initial state of the left-opening mode, the triggering protrusion 33 of the driving shaft 3 is in the triggering position of the left-opening reset position sensor 8, and the transmission protrusion 32 of the driving shaft 3 is close to the first transmission end 421 of the movable slide 42 of the driven shaft 4; when the control mechanism is in the initial state of the right-opening mode, the triggering protrusion 33 of the driving shaft 3 is in the triggering position of the right-opening reset position sensor 9, and the transmission protrusion 32 of the driving shaft 3 is close to the second transmission end 422 of the movable slide 42 of the driven shaft 4. When installing, the lock body mechanism 1 adjusts the extension and retraction direction of the lock tongue 11 by switching the installation mode of the left door opening and the installation mode of the right door opening by flipping 180° vertically. Therefore, when the mode state of the control mechanism matches the installation state of the lock body mechanism 1: when the electronic lock is set to open the door on the left, the forward rotation direction of the transmission member 12 is the same as the forward rotation direction of the transmission shaft 2; when the electronic lock is set to open the door on the right, the forward rotation direction of the transmission member 12 is opposite to the forward rotation direction of the transmission shaft 2.

[0070] During installation, the lock mechanism 1 is in an unlocked state. After the lock mechanism 1 and the control mechanism are installed on the door body and the control mechanism is powered on, the control module 50 starts a self-detection program. The control module 50 determines whether the control mechanism is currently in a left-opening mode or a right-opening mode according to the trigger signals of the left-opening reset position sensor 8 and the right-opening reset position sensor 9.

[0071] This embodiment is preset to the right-opening mode, and the following is an example of the initial setting state of the control mechanism being the right-opening mode:

[0072] The driver 5 applies a reverse rotational motion tendency to the driving shaft 3, so that the transmission protrusion 32 of the driving shaft 3 abuts against the first transmission end 421 of the movable slideway 42 to give the driven shaft 4 a reverse rotational motion tendency;

[0073] If the driven shaft 4 can be driven by the driving shaft 3 to rotate 90° in the opposite direction, the transmission shaft 2 coaxially fixed with the driven shaft 4 drives the transmission member 12 to rotate 90° in the forward direction and drives the lock tongue 11 to extend. During this period: the triggering protrusion 33 of the driving shaft 3 is driven to move and stops triggering the right door reset sensor 9, and at the same time, the magnet 45 on the driven shaft 4 moves from the triggering position of the unlocking monitoring sensor 20 to the triggering position of the right door lock monitoring sensor 40. According to the changes in the triggering signals of the right door reset sensor 9, the unlocking monitoring sensor 20, and the right door lock monitoring sensor 40, the control module 50 can know that the mode state of the control mechanism matches the installation state of the lock body mechanism 1, and then know that the electronic lock is installed on the right door. Then, the driver 5 drives the active shaft 3 to rotate 90° in the positive direction, so that the transmission protrusion 32 on the active shaft 3 moves from the position close to the second transmission end 422 along the movable slide 42 to the position close to the first transmission end 421. The driver 5 continues to drive the active shaft 3 to rotate 90° in the positive direction, so that the transmission protrusion 32 abuts against the first transmission end 421 to push the driven shaft 4 to rotate 90° in the positive direction, so that the transmission shaft 2 coaxially fixed with the driven shaft 4 drives the transmission member 12 to rotate 90° in the opposite direction and drives the lock tongue 11 to retract, thereby realizing the reset of the lock body mechanism 1 to the unlocked state. The driver 5 drives the driving shaft 3 to rotate 90° in the opposite direction, so that the transmission protrusion 32 on the driving shaft 3 moves from the position close to the first transmission end 421 to the position close to the second transmission end 422 along the movable slide 42, and the triggering protrusion 33 on the driving shaft 3 moves to the triggering position of the right opening reset position sensor 9, thereby realizing the reset of the control mechanism to the initial state of the right opening mode. Finally, the control module 50 starts the right opening control program and enters standby mode.

[0074] If the driven shaft 4 cannot be driven by the driving shaft 3 to rotate in the opposite direction, the triggering protrusion 33 of the driving shaft 3 will continue to trigger the right opening reset position sensor 9, and the magnet 45 on the driven shaft 4 will continue to trigger the unlocking monitoring sensor 20. According to the triggering signals of the right opening reset position sensor 9 and the unlocking monitoring sensor 20, the control module 50 can know that the mode state of the control mechanism does not match the installation state of the lock body mechanism 1. The control module 50 controls the driver 5 to drive the driving shaft 3 to rotate forward 90°, so that the transmission protrusion 32 of the driving shaft 3 moves from the position close to the second transmission end 422 along the movable slide 42 to the position close to the first transmission end 421. The driver 5 drives the driving shaft 3 to continue to rotate forward 90°, so that the triggering protrusion 33 of the driving shaft 3 moves to the triggering position of the left opening reset position sensor 8, thereby switching the control mechanism to the left opening mode. The driver 5 continues to drive the active shaft 3 to rotate 90° in the positive direction, so that the transmission protrusion 32 of the active shaft 3 abuts against the second transmission end 422 and pushes the driven shaft 4 to rotate 90° in the positive direction. The transmission shaft 2 coaxially fixed with the driven shaft 4 drives the transmission member 12 to rotate 90° in the positive direction and drives the lock tongue 11 to extend. During this period: the triggering protrusion 33 of the active shaft 3 is driven to move and stops triggering the left-open reset position sensor 8. At the same time, the magnet 45 on the driven shaft 4 moves from the triggering position of the unlocking monitoring sensor 20 to the triggering position of the left-open door locking monitoring sensor 30. According to the changes in the triggering signals of the left-open reset position sensor 8, the unlocking monitoring sensor 20, and the left-open door locking monitoring sensor 30, the control module 50 can thus know that the mode state of the control mechanism matches the installation state of the lock body mechanism 1, and then know that the electronic lock is installed on the left-open door; then, the driver 5 drives the active shaft 3 to rotate 90° in the opposite direction, so that the transmission protrusion 32 on the active shaft 3 moves from the position close to the first transmission end 421 to the position close to the left-open door locking monitoring sensor 30. The position moves along the movable slide 42 to a position close to the second transmission end 422, and the driver 5 continues to drive the active shaft 3 to rotate 90° in the opposite direction, so that the transmission protrusion 32 abuts on the second transmission end 422 to push the driven shaft 4 to rotate 90° in the opposite direction, so that the transmission shaft 2 coaxially fixed with the driven shaft 4 drives the transmission member 12 to rotate 90° in the opposite direction and drives the lock tongue 11 to retract, thereby realizing that the lock body mechanism 1 is reset to the unlocked state, and the magnet 45 on the driven shaft 4 moves from the trigger position of the unlocking monitoring sensor 20 and the left door locking monitoring sensor 30 to the trigger position of the unlocking monitoring sensor 20; the driver 5 drives the active shaft 3 to rotate 90° in the forward direction, so that the transmission protrusion 32 on the active shaft 3 moves from a position close to the second transmission end 422 along the movable slide 42 to a position close to the first transmission end 421, and the triggering protrusion 33 on the active shaft 3 moves to the trigger position of the left opening reset position sensor 8, thereby realizing that the control mechanism is reset to the initial state of the left opening mode. Finally, the control module 50 starts the left opening control program and enters standby mode.

[0075] Through the above steps, no matter the electronic lock is set on the left or right door, the lock tongue 11 of the locking mechanism needs to complete an unlocking and locking action, so that the installer can easily confirm that the electronic lock can work normally after the installation is completed.

[0076] Through the above design, no matter the electronic lock is set on a left-opening door or a right-opening door, the control mechanism and the lock body mechanism 1 have only one assembly method. The uniqueness of the assembly method can effectively prevent the electronic lock from being operated incorrectly during installation and affecting the normal use of the electronic lock, making the installation more convenient.

[0077] The unlocking and closing steps of the electronic lock when in use are shown in Table 2 below. By cooperating between the transmission protrusion 32 of the active shaft 3 and the movable slideway 42 of the driven shaft 4, the active shaft 3 and the driven shaft 4 can be separated from each other when the transmission shaft 2 is driven to rotate by the manual operating member 60 outside the door or the manual operating member 70 inside the door. This avoids the need to overcome the resistance of the driver 5 to drive the transmission shaft 2 to rotate when the electronic lock is manually unlocked and locked, reduces the force required for manual unlocking and locking, and is more convenient to use.
