The lock shown in fig. 3 is only one specific implementation of an embodiment of the present invention. It will be understood by those skilled in the art that the lock device shown in fig. 4 includes a second bluetooth unit, a second identification unit, a second storage unit and a second processing unit, wherein the second bluetooth unit, the second identification unit and the second storage unit are respectively connected to the second processing unit, and the second processing unit controls the second bluetooth unit, the second identification unit and the second storage unit to operate.
In addition, in order to further realize the functions of the lock, the lock further preferably comprises an unlocking unit, a display unit, a detection unit, a trigger unit and a power supply unit, wherein the unlocking unit, the display unit, the detection unit and the trigger unit are respectively connected with the second processing unit, as shown in fig. 5. Wherein:

In the lock according to the preferred embodiment of the present invention, the unlocking unit has a mechanical structure in which the deceleration motor drives the unlocking shaft, and the unlocking unit has a member, such as a torsion spring, therein which applies rotational resistance to the deceleration motor. As shown in fig. 6a and 6b, the unlocking unit includes a reduction motor, a driving gear 112, a driven gear 113, an unlocking shaft 114, and a torsion spring 115. The motor shaft 111 of the speed reduction motor is provided with the driving gear 112, the driven gear 113 is rotatably sleeved on the unlocking shaft 114, the driving gear 112 is meshed with the driven gear 113, and the motor shaft 111 drives the driving gear 112 to rotate, so that the driven gear 113 drives the unlocking shaft 114 to rotate, the unlocking shaft drives the unlocking part in the unlocking mechanism to rotate, and the unlocking operation of the lock is realized. Specifically, the unlocking shaft 114 includes a rotating shaft 1141, a circular truncated cone 1142, an unlocking portion 1143 and a first bump 1144, the rotating shaft 1141 is disposed at the center of the circular truncated cone 1142 and protrudes at least from a first side of the circular truncated cone 1142, the first bump 1144 is disposed at an edge of the first side of the circular truncated cone 1142, and the unlocking portion 1143 is disposed at a second side of the circular truncated cone 1142. The driven gear 113 is rotatably sleeved on the edge of the circular platform 1142 of the unlocking shaft, and a second bump 1131 is arranged on the driven gear 113 in the same direction as the first side of the circular platform 1142 of the unlocking shaft. The torsion spring 115 is rotatably sleeved and limited between the rotating shaft 1141 of the unlocking shaft and the first protrusion 1144, preferably, the limiting member 1145 is rotatably limited on the rotating shaft 1141 of the unlocking shaft, and the first arm 1151 and the second arm 1152 of the torsion spring 115 extend out of the rotating areas of the second protrusion 1131 of the driven gear 113 and the first protrusion 1144 of the unlocking shaft.
The unlocking shaft 114 rotates in a forward direction to unlock the lock, and the unlocking shaft 114 rotates in a reverse direction to lock the lock. The torsion spring 115 is arranged in a manner that in the lock unlocking position, the torsion spring 115 abutting against the second lug 1131 of the driven gear 113 and the first lug 1144 of the unlocking shaft applies positive rotation resistance opposite to the unlocking action to the driven gear 113, and the positive rotation resistance is transmitted to the speed reduction motor through the driving gear 112; in the latch locked position, the torsion spring 115, which is in reverse abutment against the second tab 1131 of the driven gear 113 and the first tab 1144 of the unlocking shaft, applies a reverse rotational resistance to the driven gear 113 opposite to the locking action. In the unlocking process of the lock from the locking position to the unlocking position, for example, in the locking position, the first arm 1151 of the torsion spring 115 abuts against the first protrusion 1144, the second arm 1152 of the torsion spring 115 abuts against the second protrusion 1131, the reduction motor rotates to drive the driving gear 112 to rotate, the driving gear 112 engages with the transmission driven gear 113 to drive the unlocking shaft 114 to rotate, and the reverse elastic potential energy of the torsion spring 115 starts to be gradually released, after the unlocking shaft 114 rotates to exceed the equilibrium position of the torsion spring 115, the rotating shaft continues to rotate, so that the first arm 1151 of the torsion spring 115 abuts against the second protrusion 1131, the second arm 1152 of the torsion spring 115 abuts against the first protrusion 1144, the forward elastic potential energy of the torsion spring 115 increases gradually, and the unlocking shaft 114 overcomes the forward rotation resistance of the torsion spring 115 to unlock the lock. The locking process of the lock from the unlocked position to the locked position is opposite to the unlocking process of the lock.
The display unit is used for displaying the wireless connection state, the locking and unlocking state of the lockset and displaying prompt information, wherein the prompt information can be displayed according to the operation of an operation ticket in the unlocking equipment.
The locking state detection unit is used for detecting the unlocking and locking states of the lockset. In a preferred embodiment, the locking state detection unit includes a magnetic steel and a hall element respectively and correspondingly arranged at corresponding positions of a lock hook and a lock body of the lock. When the lockset is in a locking state, the magnetic steel and the Hall element on the lock hook and the lock body are close to each other to generate an electromagnetic signal; when the lockset is in an unlocking state, the magnetic steel and the Hall element on the lock hook and the lock body are far away from each other, and no electromagnetic signal is generated. The locking state detection unit determines the unlocking and locking state of the lockset by detecting the electromagnetic signal.
The current detection unit is used for detecting the load current generated by the speed reduction motor due to the rotation resistance. As described above, the rotational resistance is provided by the torsion spring 115. When the lock is unlocked, the second processing unit starts the speed reducing motor, the speed reducing motor rotates, when the load current detected by the current detection unit is increased sharply and reaches the first current threshold, the second processing unit stops supplying power to the speed reducing motor, the speed reducing motor stops rotating, and at the moment, if the locking state detection unit detects that the lock is changed from the locking state to the unlocking state, the lock is unlocked. Specifically, during unlocking, as the unlocking shaft 114 rotates, the torsion spring 115 applies resistance to the unlocking shaft 114 after passing through its equilibrium position, so that the load current generated by the reduction motor driving the unlocking shaft 114 sharply increases. And when the load current reaches the first current threshold value, stopping supplying power to the speed reducing motor, and stopping rotating the speed reducing motor. At this time, if the unlocking mechanism of the lock is completely unlocked, the locking state detection unit can detect the change of the lock from the locking state to the unlocking state, and the unlocking process is indicated to be completed. When the lock is locked, in response to the detection of the change from the unlocked state to the locked state by the lock state detection unit, the second processing unit controls the deceleration motor to rotate reversely to drive the unlocking shaft 114 to rotate, the torsion spring 115 applies resistance to the unlocking shaft 114 after passing through the balance position of the torsion spring, and the load current generated by the deceleration motor is increased sharply. And when the load current detected by the current detection unit is increased sharply and reaches a second current threshold value, the power supply to the speed reduction motor is stopped, and the lock is locked. The first current threshold and the second current threshold are preset according to the position of the torsion spring 115 between the driving gear 112 and the driven gear 113 and the force of the torsion spring 115, and are smaller than the locked-rotor current value of the speed reduction motor.
The trigger switch can be a capacitive sensor or a button and is used for waking up the second Bluetooth unit of the lock from a low power consumption mode to a working mode. When an operator enters a certain area and wants to operate the lock in the area, the operator manually opens the trigger switch of each lock, the second Bluetooth unit of each lock is switched from a low power consumption mode to a working mode, and the second Bluetooth unit sends broadcast information comprising the identification code of the lock outwards.
