A hidden-lock door panel for use in a container includes a door panel body, a covering lid, a first lock, and a second lock. The door panel body includes a hidden space. The covering lid is disposed corresponding to the hidden space and slidably connected to the door panel body. The first lock and the second lock are both disposed in the hidden space. The first lock is an electronic lock and is used to control whether the covering lid can be released to slide. The second lock is used to control the door panel body to be unlocked or locked with respect to the container. Accordingly, unknowing persons are prevented from opening or breaking the door lock.

Provided is an outer handle device for a vehicle door includes an outer handle and a cover. The outer handle includes a handle body that is disposed outside an outer panel of the vehicle door and extends in a front-rear direction of a vehicle. The cover is configured to cover, from an outside of the vehicle door, a cylinder lock located in a position adjacent to a first end of the handle body. The cover is configured to be attached to the outer panel and has an extension part, and the outer handle is turnable between a non-operation position and an operation position. While the outer handle is in the non-operation position, the extension part is engaged with a first end of the handle body and overlaps the first end of the handle body in a side view. While the outer handle is in the operation position, the engagement between the extension part and the first end of the handle body is released, and the cover is attachable to and detachable from the outer panel.

A rotary locking mechanism and a lock applying the rotary locking mechanism and a locking control method are provided. A rotary output member is locked by a stable triangular supporting structure between the first locking member and the second locking member, the effective constraint of the second locking member on the first locking member applied by the first locking member in both a locked state and an unlocked state achieves locking and unlocking reliability of the product. The entire locking mechanism is controlled by the same switching member. The false locking operation when the rotary member is operating is effectively avoided through the mechanical structure and the automatic control method. The entire rotary locking mechanism is enclosed and fixed in a shell of the lock, and can be applied to transmission machinery of bicycles, electric vehicles, motorcycles and even lightweight automobiles.

Described herein are example fluid guards that can be used with locking devices. Various aspects may be particularly applicable to electrical locks, but they may also be applicable to mechanical locks. A locking device guard can include a guard cover, a fluid absorber, and a coupling element. The fluid absorber can be configured in a closed configuration to fit at least partially within a cup of a lock face. The coupling element can be configured to couple the guard cover to the lock and can define a second axis. The coupling element can be configured to allow the guard cover to rotate about the second axis.
