A self-locking mechanism and an electronic device with the same are provided. The self-locking mechanism includes: a housing having a through hole and a dodge hole; an elastic member in the dodge hole, the elastic member being connected to a wall of the dodge hole and having a free end capable of swinging in a thickness direction of the housing; a first engaging member on the elastic member; a knob on an outer side of the housing and having one end passing through the through hole; a plurality of second engaging members on a side of the knob adjacent to the housing; wherein the first engaging member may be engaged with or disengaged from one of the second engaging members under an action of an elastic deformation of the elastic member as the knob rotates; and a driven member on an inner side of the housing and fixedly connected with the knob so as to be rotated under driving of the knob.

A hood stay device for a vehicle includes a housing, support, and latch. A proximal end of the housing is pivotably coupled to the hood or vehicle body. An inner end of the support is within the housing. The support extends through a distal end of the housing to an outer end of the support that is pivotably coupled to the other one of the hood or vehicle body. The support is slidable relative to the housing along an axis and includes teeth arranged in a rack along the axis. The latch is coupled to the housing and movable between locked and unlocked positions relative thereto. When in the locked position, the latch engages the teeth to inhibit movement of the support member along the axis. When in the unlocked position, the latch is apart from the teeth to permit movement of the support along the axis.

The presently disclosed adjustable slide knob addresses the Backing-Off problem present with various conventional nuts. The adjustable slide knobs can be quickly positioned along a threaded rod by applying pressure to an exposed surface of a partially threaded nut. When the knob is placed against a work surface and the user releases pressure from the partially threaded nut, the thread pattern on the partially threaded nut meshes with the matching thread pattern on the threaded rod. The device can then be twisted, which will translate the device along the threaded rod, to apply a larger load to the work surface. The threaded rod may include one or more key-ways shaped to allow a locking tab housed within the knob to stop the device from freely disengaging the threaded rod to protect a user from potential injury caused by the fastener unexpectedly backing off and disengaging.

A lock structure is constituted of a gear and an engagement/disengagement switching section. The gear is disposed concentric with a turning center of an operating lever. The engagement/disengagement switching section is provided with an engagement pawl such that the engagement pawl can move toward and away from the gear. The engagement pawl is connected to a switching lever to form a substantially T-like shape, and the switching lever is pivotally supported by a body section of the engagement/disengagement switching section. A locking operation of the switching lever switches between the locked state and unlocked state of the operating lever. In an engaged state, a gap having an opening angle of in a direction in which the operating lever loosens is formed between a tooth groove of the gear and the engagement pawl.

A cup holder includes a coupling member that causes a locking pawl to be engaged with a locking recess when a cam plate is catching a beverage container, and causes the locking pawl to be disengaged from the locking pawl when the cam plate does not catch the beverage container.

The subject matter of this specification can be embodied in, among other things, a track lock assembly that includes a pawl assembly comprising a pawl arm extending from a pawl axis and configured to engage a slot in a slider assembly, a cam arm extending from the pawl axis and having a pawl cam, and a compliant member, and a position lock assembly comprising a first lock arm extending from a lock axis and an actuator configured to urge rotation of the first lock arm between a lock locked position and a lock unlocked position, the first lock arm configured to engage and retain the cam arm in a pawl locked position when the first lock arm is in the lock locked position and disengage the cam arm in the lock unlocked position such that the compliant member is able to urge the pawl assembly to a pawl unlocked position.
