A movement mechanism applied to an inner-folding flexible screen terminal, comprising an intermediate support structure, the intermediate support structure being provided with a flexible screen support surface, a left-side rotation connection structure and a right-side rotation connection structure, a left-side connecting member and a right-side connecting member; inner ends of the left-side rotation connection structure and the right-side rotation connection structure are both rotatably connected to the intermediate support structure, the left-side connecting member and the right-side connecting member are respectively rotatably connected to outer ends of the left-side rotation connection structure and the right-side rotation connection structure, and the left-side connecting member and the right-side connecting member are respectively slidably connected to a left-side support frame and a right-side support frame. By means of the pressing of a pressing structure to the rotation structure, when a flexible screen mobile terminal is unfolded, the left and right casings can be prevented from rotating and shaking, and the unfolded state is stably maintained; and it is suitable for adopting multiple segments of rotation structures to cooperate with the pressing structure, thereby reducing the risk of getting stuck during rotation.

A coupling element for a positioning device, which includes a first and second linear guides for guiding first and second carriages respectively along first and second linear directions, is configured to create a coupling between the first carriage and the second linear guide. The coupling element includes a central part and a surrounding part spaced at a distance therefrom. The surrounding part has a central portion surrounding the central part, and has two end portions adjoining the central portion in the first linear direction. Connecting flat springs are disposed to create the distance and connect together the central part and the central portion of the surrounding part. The connecting flat springs lie in planes which intersect at a center of the central part. A vertical flat spring is disposed parallel to the first linear direction at each of the two end portions of the surrounding part.

An auxiliary support and an external image capturing device. The auxiliary support includes a hooking member, a supporting member and a buffer member. The hooking member is configured to be hooked to a top of a first external structural member. One end of the supporting member is connected to the hooking member. The buffer member is connected to the end of the supporting member away from the hooking member and can deform plastically. The supporting member can be bent or curved such that the buffer member can abut against a second surface when the hooking member is hooked to the first external structural member. The buffer member can increase a supporting area, prevent the auxiliary support from shaking, reduce the pressure of the auxiliary support on the first external structural member, and prevent scratch or deformation of the first external structural member.

A hinge includes internal on-axis stopping mechanisms that cause the hinge to shear and break at an on-axis weakened region of the hinge when rotation of the hinge reaches a predetermined angle with a specified torsional load. The on-axis configuration is compact, has minimal impact on the outer mold line (OML) of the object to which it is mounted both pre and post detachment and allows for accurate tailoring of the torsional load that will detach the hinge.

A fastening apparatus includes: a base having a first sliding groove; a rotation member pivotally connected to the base and having at least two locking states, the rotation member has a second sliding groove; a locking member having a locked state and an unlocked state, in the locked state, the rotation member is located in both the first sliding groove and the second sliding groove; in the unlocked state, the locking member is withdrawn from the first sliding groove or the second sliding groove to allow the rotation member to rotate relative to the base; an elastic element configured to maintain the locking member in the locked state; and a releasing member configured to drive the locking member to move against an elastic force of the elastic element, such that the locking member is switched from the locked state to the unlocked state.

An electronic device includes a display, and a hinge assembly foldable together with the display and corresponding to a folding area of the display. The hinge assembly includes a hinge bracket defining first and second hinge axes, first and second rotators connected to the hinge bracket and respectively rotatable about the first and second hinge axes, first and second sliders connected to the hinge bracket, respectively slidable relative to the hinge bracket in a direction parallel with the hinge axes, and spaced apart from each other in the direction, and an elastic member between the first and second sliders and providing an elastic force in the direction. The first and second rotators respectively include first and second helical structures having a helical shape with the first and second hinge axes as a center, and are each connected to the first and second sliders through the first and second helical structures.

An aircraft assembly includes a first body connected to a second body via a flexible coupling that limits separation of the bearing faces while permitting relative rotational movement between the bodies. The flexible coupling includes one or more first flexible straps attached to the first side of the first body and attached to the second side of the second body, and one or more second flexible straps attached to the second side of the first body and attached to the first side of the second body.
