Detailed Description
The invention will be further described in detail with reference to examples of embodiments shown in the drawings.
Referring to fig. 1-4, an unlocking mechanism of the present embodiment includes a trigger member 1 and an unlocking member 2, where the trigger member 1 is configured to cooperate with the unlocking member 2 to perform an unlocking action, and further includes a connecting member 3, where the connecting member 3 is rotatably disposed at a certain point, one end of the connecting member 3 is connected to the trigger member 1, the other end of the connecting member 3 is connected to the unlocking member 2, the trigger member 1 drives the connecting member 3 to rotate, and the connecting member 3 drives the unlocking member 2 to perform the unlocking action through rotation.
The trigger piece 1 can adopt structures such as a push button, a pull type pull rod and the like, and is connected with one end of the connecting piece 3 in a hinging way (such as pin shaft fit and key slot fit), so that the linear motion or rotation energy of the trigger piece 1 can be effectively transmitted to the connecting piece 3, a positioning point of the connecting piece 3 can be realized through a rotating shaft fixed on a mechanism shell or through the rotating shaft on the connecting piece 3 being connected with the mechanism shell, the connecting piece 3 forms a lever structure around the rotating shaft, the force transmission direction and distance can be changed in the rotating process, and the unlocking piece 2 can adopt structures such as a deflector rod and a cam, and is matched with or hinged with the other end of the connecting piece 3 through a clamping groove. When the trigger piece 1 is operated (for example, a button is pressed to move downwards, and a pull rod is pulled to move outwards), the trigger piece 1 drives the connecting piece 3 to rotate around a locating point, and the other end of the connecting piece 3 pushes or pulls the unlocking piece 2 to enable the unlocking piece 2 to execute unlocking actions (for example, a lock tongue is pushed to retract). Through the rotation transmission of the connecting piece 3, even if a longer distance exists between the trigger piece 1 and the unlocking piece 2 or the trigger piece is not in the same straight line direction, the trigger piece and the unlocking piece can still be linked stably, the limitation that the trigger piece and the unlocking piece can be linked only by direct contact in the prior art is solved, the installation position selection range of the trigger piece 1 is enlarged, and the layout flexibility of the mechanism is improved.
In an alternative embodiment, the unlocking member 2 performs the unlocking action by rotating, and the unlocking member 2 is rotated by the connecting member 3.
The unlocking piece 2 is rotatably arranged through a fixed rotating shaft (such as a pin shaft arranged on the shell or a pin shaft arranged on the unlocking piece 2), an eccentric matching position is arranged at the connecting end of the unlocking piece and the connecting piece 3, and the end part of the connecting piece 3 is inserted into the eccentric matching position to form eccentric connection. When the trigger piece 1 drives the connecting piece 3 to rotate around the self locating point, the end part of the connecting piece 3 pushes the unlocking piece 2 to rotate around the fixed rotating shaft of the unlocking piece through the eccentric matching position, and the rotation of the unlocking piece 2 directly drives the subsequent locking component (such as a lock tongue) to complete unlocking. Compared with the linear motion of the unlocking piece 2, the rotary motion is easier to adapt to complex space layout, and the power is transmitted through eccentric connection, so that the clamping stagnation phenomenon in the transmission process can be reduced, and the stability and reliability of the unlocking motion are improved.
Moreover, this rotational approach may be used to simultaneously bring multiple locking members to unlock, such as the two locking members shown in fig. 1, 2, and 4.
As an embodiment capable of increasing the unlocking mode, the unlocking device further comprises an electric actuator 4, wherein the electric actuator 4 is matched with the unlocking piece 2 and is used for driving the unlocking piece 2 to rotate.
The electric actuator 4 may be a direct current motor, and its output shaft is engaged with the unlocking member 2 through a gear (such as a motor shaft gear engaged with a sector gear on the unlocking member 2) or a link mechanism (such as a motor output shaft crank, the crank is hinged with the unlocking member 2 through a link). When the electric unlocking is needed, the electric actuator 4 is electrified to work, the output end of the electric actuator directly drives the unlocking piece 2 to rotate around the rotating shaft of the electric actuator to realize the unlocking action, and when the electric actuator is needed to be manually unlocked, the triggering piece 1 can still drive the unlocking piece 2 to rotate through the connecting piece 3, and the two driving modes are independent and do not interfere with each other. The structure realizes a manual and electric dual-drive mode, is applicable to different scenes (such as manual operation during power failure and electric operation during remote control), improves the applicability and emergency capability of the unlocking mechanism, and meanwhile, has a simple matching structure of the electric actuator 4 and the unlocking piece 2, and is easy to integrate.
Of course, the output shaft of the electric actuator 4 may push the unlocking member 2 to rotate in a telescopic manner.
In order to reduce the interference between the electric unlocking and the manual unlocking, in an alternative embodiment, the unlocking member 2 is provided with a avoidance position 5 corresponding to the position of the connecting member 3, and the connecting member 3 is kept at the avoidance position 5 when the electric actuator 4 drives the unlocking member 2 to rotate.
The avoidance position 5 is an arc-shaped groove or a through hole or a notch formed in the unlocking piece 2, the size of the avoidance position is larger than the connecting end part of the connecting piece 3 and the unlocking piece 2, and the track of the avoidance position 5 is matched with the rotating track of the unlocking piece 2. When the electric actuator 4 drives the unlocking piece 2 to rotate, the end part of the connecting piece 3 is positioned in the avoidance position 5, no contact and no acting force transmission exist between the end part and the unlocking piece, namely the connecting piece 3 is kept static (not rotating along with the unlocking piece 2), the blocking of the connecting piece 3 to the electric rotation of the unlocking piece 2 is avoided, and when the trigger piece 1 is manually operated, the connecting piece 3 rotates and pushes the unlocking piece 2 to rotate through the inner wall of the avoidance position 5, so that manual driving is realized. The arrangement of the avoidance bit 5 ensures the independence of electric driving and manual driving, solves the problem of motion interference possibly generated by two driving modes, improves the smoothness of mechanism operation, and simplifies the coordination control logic of double driving.
Optionally, the output end of the electric actuator 4 is provided with a rotating member 6, the rotating member 6 is driven to rotate by the electric actuator 4, and the rotating member 6 is connected with the connecting member 3 to drive the connecting member 3 to rotate.
The rotating member 6 may be a gear or a swing arm, the output shaft of the electric actuator 4 (such as a motor) is fixedly connected (such as a key connected) with the rotating member 6, the rotating member 6 is meshed with the connecting member 3 through a gear (such as the rotating member 6 is a driving gear, a rack section is arranged on the connecting member 3), or is in contact fit (refer to fig. 2, 3 and 4, the rotating member 6 is a swing arm, and the unlocking member 2 is provided with a component capable of contacting with the swing arm, and at this time, when the swing arm acts, the component capable of contacting with the swing arm drives the unlocking member 2 to rotate, for example, the contacted component is a protrusion). When the electric actuator 4 works, the rotating piece 6 is driven to rotate, the rotating piece 6 drives the connecting piece 3 to rotate around the locating point thereof through meshing or contact fit, and then the unlocking piece 2 is driven to rotate through the connecting piece 3. The structure enables electric driving power to be transmitted to the unlocking piece 2 through the connecting piece 3, shares the same transmission path with manual driving, simplifies the integral structure of the mechanism, reduces the number of parts, reduces assembly difficulty and cost, and improves the power transmission efficiency of two driving modes.
In still a further alternative arrangement, the horizontal plane in which the rotation direction of the unlocking member 2 is located and the horizontal plane in which the rotation direction of the connecting member 3 is located are arranged vertically or at an included angle. The space layout design enables the trigger piece 1 and the unlocking piece 2 to be respectively arranged on different horizontal planes, and solves the linkage difficulty caused by space positions of the trigger piece 1 and the unlocking piece.
The unlocking mechanism and various optional embodiments thereof are introduced and can be cited in an electric lockset, and the scheme is that the electric lockset comprises a locking mechanism, a locked part and the unlocking mechanism according to any embodiment, wherein the unlocking member 2 of the unlocking mechanism drives the locking mechanism to unlock or lock the locked part.
The locking mechanism can adopt a lock tongue assembly (comprising a lock tongue and a lock tongue seat), the locked part is a door body or a drawer or a lock beam 7, the lock tongue seat is fixed in a lock shell, the lock tongue is slidably arranged on the lock tongue seat, and the unlocking piece 2 is connected with the lock tongue through a cam structure (the cam edge is contacted with the end part of the lock tongue). When the unlocking mechanism executes unlocking action, the unlocking piece 2 rotates, the cam pushes the lock tongue to retract into the lock tongue seat (separate from the lock hole on the locked component) to unlock the locked component, when the unlocking piece 2 rotates reversely, the cam releases the lock tongue, the lock tongue stretches out and inserts into the lock hole under the action of the reset spring to realize locking, or when the unlocking piece 2 rotates reversely, the lock tongue is driven to move and insert into the lock hole to lock. This electric lock has inherited its trigger 1 and has set up nimble advantage through integrating above-mentioned release mechanism, has solved the problem that trigger 1 and lock body must closely arrange among the traditional electric lock, has promoted the installation convenience and the user experience of tool to lock.
Besides, the padlock can also comprise the following technical scheme that the padlock comprises a lock beam 7, a locking mechanism, the unlocking mechanism of any one embodiment and a coded wheel assembly 11, wherein when the code of the coded wheel assembly 11 is correct, the movement restriction of the trigger piece 1 is released, otherwise, the trigger piece 1 is restricted to move, and the unlocking piece 2 of the unlocking mechanism drives the locking mechanism to unlock or lock the lock beam 7. The password wheel assembly 11 can adopt the technical scheme in the prior art, and the trigger piece 1 (button) can be interacted or not interacted through locking and unlocking of the password assembly 11 wheels, and can be manually unlocked when being interacted. Especially under the condition that the electric unlocking scheme with the electric actuator is adopted to be matched with each other, the electric and manual double-driving effect can be achieved, and the manual emergency unlocking can be carried out under the condition that the electric unlocking power failure can be achieved by combining the password wheel assembly 11. The specific electric actuator can be identified and controlled through fingerprint identification, NFC, bluetooth, IRFD and other identity authentication schemes in the prior art.
The lock beam 7 is of a U-shaped structure, one end of the lock beam 7 is hinged to the padlock shell, the other end of the lock beam is telescopic, the locking mechanism is used for limiting the telescopic movement of the free end of the lock beam 7, and the unlocking piece 2 is connected with the locking mechanism through a connecting rod. When the padlock is in a locking state, the locking mechanism clamps the free end of the lock beam 7, when the unlocking mechanism acts, the unlocking piece 2 drives the locking mechanism to release the lock beam 7 through the connecting rod, the lock beam 7 pops up (unlocks) under the action of self elasticity or a spring, when the lock beam 7 is pressed to retract the free end into the shell, the unlocking piece 2 drives the locking mechanism to clamp the lock beam 7 again (locking) or the lock beam 7 props up the locking mechanism, and after the lock beam 7 is inserted in place, the locking mechanism locks the lock beam 7 again under the action of the elasticity of the spring. The unlocking mechanism is applied to the padlock, so that the trigger piece 1 (such as a password keyboard and a fingerprint module) of the padlock can be flexibly arranged at any position of the shell (without being directly aligned with the locking mechanism), the problem that the arrangement of the trigger piece 1 is limited due to the narrow internal space of the traditional padlock is solved, and the function expansibility (such as integration of various unlocking modes) of the padlock is improved.
In an alternative scheme, the locking mechanism comprises at least one lock pin 8 connected with the unlocking piece 2, a lock groove 9 is formed in the lock beam 7 at a position corresponding to the lock pin 8, when the lock pin 8 is inserted into the lock groove 9, the lock beam 7 is limited to be separated to lock the lock beam 7, and when the unlocking piece 2 rotates, the lock pin 8 is driven to be separated from the lock groove 9 to unlock or the lock pin 8 is driven to be inserted into the lock groove 9 to lock.
The lock pin 8 is slidably arranged in a guide structure of the padlock shell, one end of the lock pin 8 is connected with the unlocking piece 2, the other end of the lock pin is wedge-shaped (convenient to be inserted into the lock groove 9 and jacked up by the lock beam 7), and the side surface of the free end of the lock beam 7 is provided with the lock groove 9 which is matched with the lock pin 8. When the padlock is locked, the lock pin 8 is inserted into the lock groove 9 to limit the axial movement of the lock beam 7, and when the unlocking piece 2 rotates, the lock pin 8 is pulled to slide along the guide structure by the connecting rod to enable the lock pin 8 to be separated (unlocked) from the lock groove 9, and the lock beam 7 can be freely ejected under the action of a spring or pulled out under the action of a manual force. The locking pin 8 and the locking groove 9 are matched with a simple and reliable structure, the locking strength is high, the unlocking piece 2 can be used for driving the locking pin 8 to move linearly, the power transmission is direct, and the locking stability and unlocking efficiency of the padlock are improved.
Preferably, the lock pin 8 is connected with an elastic component 10, the lock pin 8 keeps the moving trend towards the lock groove 9 through the elastic component 10, and/or the lock pin 8 drives the unlocking piece 2 to rotate and reset during the moving process towards the lock groove 9. The elastic member 10 is a compression spring, one end of which abuts against the padlock housing, and the other end abuts against the lock pin 8, and the spring urges the lock pin 8 in a natural state to keep a tendency to move toward the lock groove 9 (to ensure that the lock pin 8 can be reliably inserted into the lock groove 9 when locking). When unlocking, the unlocking piece 2 drives the lock pin 8 to move to overcome the elasticity of the spring to pull the lock pin 8 to be separated from the lock groove 9, after the unlocking action is finished, the external force on the unlocking piece 2 is removed, and the spring pushes the lock pin 8 to move towards the lock groove 9. The arrangement of the elastic component 10 ensures the reliable locking of the lock pin 8, avoids the release of the lock pin 8 caused by vibration and other factors, and the lock pin 8 drives the unlocking piece 2 to reset, so that a reset device (such as a torsion spring) of the unlocking piece 2 is not required to be additionally arranged, the internal structure of the padlock is simplified, the assembly cost is reduced, and the automatic reset reliability of the mechanism is improved.
Of course, the trigger piece 1 can drive the unlocking piece 2 to reset through the connecting piece 3 by setting a resetting structure. The return structure may also employ a spring.
