A latch assembly for a vehicle, in applications such as an armrest console or a glove box, includes a shape memory alloy (SMA) actuator. The SMA actuator includes an actuator housing, an SMA wire, and an actuator lever arm. The actuator lever arm is configured to pivotably rotate or linearly translate with respect to the actuator housing upon activation of the SMA wire. A connecting link is coupled to the actuator lever arm. The connecting link is configured to translate linearly along a connecting link axis when the actuator lever arm pivotably rotates or linearly translates. A striker is coupled to the connecting link and configured to rotate about a striker axis to engage a closing surface.

A lock for locking a bike is provided. To lock the bike, a user inserts a rope head into a lock through a lock hole. The rope head drives a slider in the lock, and the slider drives a pin, causing an upper-rotation shaft of the lock become not linked to move with a lower-rotation shaft of the lock. Since the upper-rotation shaft and the lower-rotation shaft of the lock are respectively connected to a handlebar and a front wheel of the bike, the user is unable to control the front wheel through the handlebar. The rope head may also be connected to a rope, and when locking the lock, the user pulls the rope out from the lock, wraps the rope around a fixed object, and then inserts the rope head into the lock through the lock hole.

A preload mechanism for a memory alloy wire actuator is disclosed that includes a rotating element configured to rotate about a pivot. The rotating element has a first contact point that is configured to couple to the memory alloy wire actuator such that contraction of the memory alloy wire actuator displaces the first contact point such that the rotating element rotates from a first position to a second position. The preload mechanism also includes a bias element with a first end that is coupled to a second contact point of the rotating element and a second end configured to be pinned relative to the pivot. The bias element has a line of action extending from the second end through the first end. The line of action has an offset distance that is the minimum distance between the line of action and the pivot. The offset distance has a first value when the rotating element is in the first position and a second value when the rotating element is the second position, the second value being smaller than the first value.

An example electronic security tag attachable to an item includes a tag body member, a connecting member having a pin portion releasably engageable with the tag body member, the pin portion extending along a first axis. The electronic security tag further includes a locking member to lock the connecting member to the tag body member. The locking member includes a clutch mechanism movable parallel to the first axis between a first position in contact with the pin portion and corresponding to a locked state and a second position corresponding to an unlocked state. The locking member further including a rotational drive member configured to rotate and interact with a plunger member of the clutch mechanism to move the clutch mechanism from the locked state to the unlocked state.

The invention relates to an anti-theft device configured to be attached to merchandise to be protected, in particular textile products, comprising a housing and a locking mechanism, which is received in the housing at least in part and comprises a securing element, wherein the securing element is adjustable between a securing position, in which it engages with the merchandise to be protected, and a release position, in which detachment and removal of the anti-theft device from the merchandise to be protected are permitted.

A lock for locking a bike is provided. To lock the bike, a user inserts a rope head into a lock through a lock hole. The rope head drives a slider in the lock, and the slider drives a pin, causing an upper-rotation shaft of the lock become not linked to move with a lower-rotation shaft of the lock. Since the upper-rotation shaft and the lower-rotation shaft of the lock are respectively connected to a handlebar and a front wheel of the bike, the user is unable to control the front wheel through the handlebar. The rope head may also be connected to a rope, and when locking the lock, the user pulls the rope out from the lock, wraps the rope around a fixed object, and then inserts the rope head into the lock through the lock hole.

A merchandise security device configured for use with an electronic key for locking and/or unlocking a lock mechanism is provided. The merchandise security device may include a housing operably coupled with a cable, wherein the cable is configured to be extended and retracted relative to the housing and to at least partially surround an item of merchandise. The security device may also include a lock mechanism configured to releasably secure the cable relative to the housing for locking the cable about the item of merchandise. In addition, the lock mechanism is configured to receive electrical power for unlocking the lock mechanism so that the housing and the cable may be removed from the item of merchandise.

A latch assembly 1 for an access door 2 of a storage compartment 3 in a vehicle 4, comprises a locking bar 5 configured to be movable into an engaged configuration which enables the access door 2 to be placed and held into a closed position and into a disengaged configuration which permits the access door 2 to be placed into an opened position; and an automatic locking mechanism 8 including a shape memory alloy (SMA) actuator 9 configured to be coupled to the access door 2, the automatic locking mechanism 8 further including a locking feature 10 operably coupled to at least a portion of the locking bar 5, 5′, and configured to engage and disengage the SMA actuator which is electrically energized to move into a locked position to prohibit the locking feature 10 from moving.

Further, a latch assembly 1 for an access door 2 of a storage compartment 3 in a vehicle 4 comprises at least one shape memory alloy (SMA) actuator 9 configured to move the locking bar 5, 5′; 26, 27 into the disengaged configuration with the storage compartment 3.

The present application discloses a combination lock including a lock body and a lock hook controlled by the lock body so as to be locked into or separated from the lock body; the lock body includes a base, an upper cover connected to the base, and a latch mechanism and a control circuit board disposed in a cavity enclosed by the base and the upper cover, the control circuit board receives an external trigger signal and controls the latch mechanism to move, achieving locking into or separation from the lock hook. Compared with the prior art, a combination lock and a notebook using the same of the present application uses fingerprint or digital touch control to perform identification, and has the control circuit board to control the movement of the motor, which automatically drives the latch piece to unlock and lock the lock body and lock hook.

An electronic article surveillance tag including a tag body member and a connecting member having a pin portion releasably engageable with the tag body member, wherein the pin portion extends along a first axis. The tag further includes a locking member having a clutch mechanism including a plunger member formed from a non-ferromagnetic material and an unlocking member connected to the clutch mechanism. The unlocking member is moveable along a second axis perpendicular to the first axis between a locked position and an unlocked position, wherein during movement between the locked position and the unlocked position, the unlocking member moves the clutch mechanism between the first position corresponding to the locked state and the second position corresponding to the unlocked state.
