A lock and lid lock for an appliance are provided. The lock has a base supporting a driving mechanism, a sliding mechanism, a connecting mechanism and a locking mechanism. The driving mechanism includes a driving unit that drives rotation of a screw rod. A sliding block is connected to a gear that is engaged with the screw rod and drives the sliding block to move linearly back and forth with the rotation of the screw rod. One end of the connecting mechanism is connected to the sliding block and the other end is connected to the locking mechanism. This allows linear movement of the sliding block to be converted into rotational movement of the locking mechanism. The locking mechanism is rotatably connected to the base and may include a locking portion which is configured to unfold or retract relative to the base along with the rotation of the locking mechanism.

An electronic drive for a lock assembly includes a housing, a motor disposed within the housing, and at least one link bar coupled to the motor. The at least one link bar at least partially extends out of the housing. The electronic drive also includes a driven disk coupled to a first end of the at least one link bar and rotatable about a rotational axis. The driven disk is adapted to couple to the lock assembly, and upon rotation, extend and retract at least one locking element. In operation, the motor selectively drives substantially linear movement of the at least one link bar to rotate the driven disk about the rotational axis.

Apparatuses, methods, and systems for providing a locking apparatus for resisting movement of an openable element are described. The locking apparatus includes a body, an actuator, a lifting member, at least a portion of the lifting member being configured to be raised or lowered relative to the body according to an output of the actuator, the lifting member comprising a contact surface configured to restrict movement of the openable element, and a strap coupled to the body and to the lifting member, the strap configured to permit the lifting member to flex based at least in part upon contact between the lifting member and the openable element and to transfer energy received at the lifting member into the body of the locking apparatus into a surface to which the locking apparatus is mounted.

A retention assembly may comprise a motor assembly and a self-locking worm drive coupled thereto. A cam may be fixed to a worm gear of the worm drive. The retention assembly may further comprise an actuation shaft including a follower. The actuation shaft may be displaceable over a displacement range via rotation of the cam. The retention assembly may further comprise a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly may further comprise a housing cam included as part of the retention assembly housing and against which the securement member follower may be biased. The securement member may be in an open state when the actuation shaft is in a first position. The securement member may swing outward to a retaining position as the actuation shaft is moved to a second position.

A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.

A door lock comprises an electromagnet (410), a latch shaft (320), a crank device (430) and the like. The crank device (430) is connected with the latch shaft (320) and driven by the electromagnet (410) to transform the linear motion of the electromagnet (410) into the rotary motion of the latch shaft (320). When the electromagnet (410) pushes or pulls the crank device (430), a latch head (202) rotates around an axis so that it can move to a locked position or an unlocked position. The door lock (200) of the present invention can transform the linear motion of the electromagnet (410) into the rotary motion of the latch head (202), so that the latch head (202) can be conveniently installed on the lateral surface rather than at an end of the door lock (200). The door lock (200) can be advantageously installed in the middle gap of a front panel (102) along an edge of a control panel of the washing machine (100) to lock the upper cover (101) from the middle part.

An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. An actuator mechanism is included in the housing, the actuator mechanism is adapted to impart linear movement on a latch, such that the latch is retracted towards the housing. A holding mechanism is also included in the housing, the holding mechanism holds the latch in a fully retracted position.

Adoor latch includes a gripper adjustable between a gripping state and a release state, which gripper, in the gripping state, is able to grip a closing member for holding the door closed which moves relatively closer to the gripper in a closing direction as a door of the domestic appliance is closed, and, in the release state, frees the closing member for opening the door, wherein, when the door is closed, the gripping state of the gripper is released by a relative releasing movement of the closing member carried out in the closing direction; and an electrically controllable displacement mechanism for displacing the gripper, under electrical control, from a retracted position into an advanced position against a restoring spring force, which advanced position, when the closing member is gripped, corresponds to a state in which the door is closed to a lesser degree than in the retracted position.

An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.

A method of allowing access to a receptacle for securing a package includes: sensing an opening and closing of the lid; activating, in response to determining the lid is sufficiently closed, the lock mechanism to transition from the unlocked state to the locked state; scanning an email message in a user's email account to identify a reference or tracking number of a second package; parsing the email message to obtain a delivery code; receiving entry of the delivery code; activating the lock mechanism based on entry of the delivery code to transition from the locked state to the unlocked state; sensing a second opening and closing of the lid; activating the lock mechanism to transition from the unlocked state to the locked state; receiving information corresponding to entry of an access code; activating the lock mechanism to transition from the locked state to the unlocked state.
