A system for controlling a motion of a door of a vehicle comprising: at least one user interface device comprising a control device, the control device being in operable communication with a door check mechanism configured for resisting the motion of the door relative to a vehicle body, wherein operation of the control device controls operation of the door check mechanism. The door check mechanism can comprise: a linkage coupled between a vehicle body and the door, the linkage configured to pivot about an axis; and a brake assembly coupled to the linkage for applying a resistive force to the linkage to resist rotation of the linkage about the axis.

A tailgate lifting apparatus is provided that includes: a first cog, a second cog, and a housing fixedly attached to a dump body. Preferably, the first cog is fixedly attached to a lower hinge pin of the tailgate, the second cog is rotatably coupled to the housing, and the second cog meshes with the first cog. The housing includes a ratcheting mechanism that selectively engages the second cog, the device therewith operable therewith to maintain the tailgate in a plurality of positions between a fully opened and fully closed positions.

A door swing control device comprises a bracket affixed to a door, a pivoting element pivotably affixed to the bracket, and a swinging catch mechanism mounted directly or indirectly to the structure. The pivoting element comprises a finger extending therefrom and is engaged with the bracket to limit a range of movement of the pivoting element relative to the bracket. The finger is engageable with the swinging catch mechanism to limit a range of movement of the pivoting element relative to the swinging catch mechanism and thereby selectively limiting a range of movement of the bracket relative to the swinging catch mechanism. When the finger of the pivoting element is engaged with the swinging catch mechanism, the door is held in the first open position. When the finger of the pivoting element is disengaged from the swinging catch mechanism, the door can swing between the first and second open positions.

A hinge structure includes: a supporting sheet having an unfolded, flattened state and a folded state; at least one first hinge connected to the supporting sheet, the at least one first hinge being configured to drive the supporting sheet to switch between the unfolded, flattened state and the folded state; at least one flattening support including a first support, a second support, and a flattening bracket, the flattening bracket being connected to the first support and the second support, the flattening bracket being connected to the supporting sheet. When the supporting sheet is in the unfolded, flattened state, the first support and the second support interact with each other and generate a force parallel to a plane where the supporting sheet is located, to maintain the supporting sheet in the unfolded, flattened state.

A hinged mobile computing device includes a first housing part with a first display and a second housing part with a second display. The first and second housing parts are coupled by a hinge assembly that includes a spring-loaded opening mechanism configured to bias with a biasing torque the first housing part and second housing part to rotate away from each other when the first and second displays are in a closed face-to-face orientation. An electro-magnetic closure system is configured to retain the first and second displays in the closed face-to-face orientation against the biasing torque of the spring-loaded opening mechanism, and release of the electro-magnetic closure system permits the first housing part to rotationally separate from the second housing part to a predetermined angular orientation due to the biasing force of the spring-loaded opening mechanism.

A vehicle door checker integrated with a power drive unit for an automobile door includes a direct current permanent magnet electric motor subject to cogging torque. The electric motor includes a central shaft. The vehicle door checker also includes a cogging torque increase device that is mounted to the central shaft externally of the motor. The cogging torque increase device includes pairs of oppositely magnetized permanent magnets that are mounted coaxially in a stator and rotor respectively about the motor shaft. The stator magnets and the rotor magnets shift into and out of alignment with each other as the shaft is rotated such that the motor is held in multiple discrete stable positions that correspond to check positions of an automobile door.

A side-open left-right-door arbitrary-opening structure of a refrigerator comprises four hinge shafts are fixedly connected at left and right sides of a refrigerator body in pairs respectively, left and right sides of upper and lower end faces of a refrigerator door are all provided with an opening neck, each hinge shaft is correspondingly placed in one opening neck, four hinge shaft stoppers are slidably arranged on the upper and lower end faces of the refrigerator door in pairs respectively, one spring is arranged between two hinge shaft stoppers in each pair, tail ends of the hinge shaft stoppers on the upper and lower end faces of the refrigerator door extend into the opening necks at the corresponding sides, and the hinge shafts at the corresponding sides are positioned in the opening necks.

A hinge device is adapted to be installed between two machine bodies that are mounted with a flexible display. The hinge device includes a base member, two rotating modules mounted respectively to opposite sides of the base member and adapted for the machine bodies to be mounted respectively thereto, and a central support plate disposed above the base member and connected between the rotating modules. The central support plate is drivable by the rotating modules to move relative to the base member from a supporting position, where the flexible display is flat and is supported thereby from below, to a receding position, where a display receiving space is provided for receiving a bent portion of the flexible display.

A door presenting device for a motor vehicle door element having an electric drive unit and an actuating means, wherein the actuating means can be adjusted by means of the drive unit and a gear mechanism arranged between the actuating means and the drive unit, with the result that a movement of the door element can be enabled, and further having a locking means. The door element can be maintained in position by means of the locking means and the locking means can be electrically actuated, namely indirectly, preferably manually, actuated.

A counterbalance mechanism for coupling with a closure panel to assist in opening and closing of the closure panel between a fully closed position and a fully open position of the closure panel, the counterbalance mechanism including: a housing coupled at one end to one of the closure panel and a body of a vehicle by a first connector and at another end by a second connector to the other of the body and the closure panel, the housing containing an extension member and a spring positioned along a longitudinal axis, the spring positioned adjacent to the first connector; the first connector having a body with a connection portion coupled by a connection to an end of the housing positioned at the one end; and a spring retention mechanism for inhibiting extension of the spring out of the one end of the housing, the spring retention mechanism including: a spring retainer positioned between the spring and the end; and a retainer pin positioned between the spring retainer and the end; wherein upon decoupling of the connection portion with the end, the retainer pin inhibits movement of the spring and the spring retainer towards the one end along the longitudinal axis.
