The second protruding member includes an outer peripheral part having higher stifffiess than that of the first protruding member. The second contact surface is disposed at an interval from the second protruding member. The second protruding member contacts the second contact surface when the torsion angle reaches a second angle greater than the first angle.

An energy-absorbing assembly includes an outer assembly with an outer hollow cylindrical member, and an inner assembly with an inner hollow cylindrical member having an end disposed in the outer member. The inner and outer assemblies are axially movably engaged with each other and define first and second cavities separated by a membrane: a first cavity inside the outer hollow cylindrical member and a second cavity inside the inner hollow cylindrical member. An adjustable-size orifice is disposed between the first and second cavities, and is configured to reduce diameter in response to a stroke motion of the energy-absorbing assembly.

A rotary device includes a first rotor, a centrifugal element, a first urging member, and a second urging member. The first rotor includes a guide surface and is disposed to be rotatable. The centrifugal element is attached to the first rotor. The centrifugal element is radially movable along the guide surface by a centrifugal force acting thereon in rotation of the first rotor. The first urging member is configured to urge the centrifugal element. The second urging member is configured to urge the centrifugal element in a direction opposite to a direction of urging by the first urging member. The first and second urging members are further configured to rotate the centrifugal element toward the guide surface.

A multi-mode air shock is disclosed herein. The air shock includes an air spring having a primary air chamber, and a damper having an insertion end to telescope within the primary air chamber and a coupler to couple with a portion of a vehicle. An adjuster housing is fixedly coupled to an end of the air spring opposite of the damper, the adjuster housing having a secondary air chamber in communication with the primary air chamber and a mounting structure to couple with a different portion of the vehicle. There is a bulkhead with a valve to open or close the fluid communication between the primary air chamber and the secondary air chamber. The air shock also includes a tertiary air chamber in fluid communication with the secondary air chamber but not in fluid communication with the primary air chamber except via the secondary air chamber.

A hinge device for supporting a display device is provided. The hinge device comprises a supporting seat, a shaft, a bearing plate, and an elastic module. The shaft rotatably passes through the supporting seat. The bearing plate is disposed on the shaft, and the display device is disposed on the bearing plate. The elastic module includes a cam and at least one elastic plate. The cam is configured on the shaft, and the cam and the shaft rotate synchronously. A fixed end of the elastic plate is fixed to the supporting seat. The elastic plate has a deformation amount to provide a balance torque to the cam when a free end of the elastic plate abuts against the cam. When an external force is applied on the display device, the bearing plate is actuated to drive the shaft and the cam to rotate to change the deformation amount and the balance torque of the elastic plate. When the external force is removed, the display device can be stopped at once.

The present invention relates to a hydraulic comprising a compression stop assembly located in a compression chamber and the compression stop assembly comprises a body; an axial member disposed slidably within said body; a covering member fixed on said axial member and provided with at least one compression flow channel and at least one rebound flow channel; a disengaging spring preloaded between said body and said covering member. The compression stop assembly further comprises a rotating member disposed pivotally with respect to said body and capable of covering at least partially said at least one compression flow channel depending on the angular position of said rotating member with respect to said at least one compression flow channel; and at least one cam configured to cooperate with said rotating member in order to change its angular position with respect to its axial displacement.

The vertical vibration isolation system of the present invention includes a bearing base, a guide rail assembly and a plurality of buckling elements. The bearing base has an upper platform that can move along a vertical direction. The guide rail assembly surrounds the bearing base and has a plurality of arc-shaped sliding channels. The top portion of each buckling element can move with the upper platform, while the bottom portion of each buckling element is slidably connected to the corresponding arc-shaped sliding channel. The vertical displacement of the upper platform would cause different degrees of buckling of the buckling elements and also induces sliding motion of the bottom portion of the buckling elements along the arc-shaped sliding channels. Accordingly, the vertical vibration isolation system can provide nonlinear restoring force by buckling and sliding mechanisms so as to exhibit vertical vibration isolation effect.

A torsional vibration damper comprises an axially movable locking piston including a piston plate, a torque input member including a cover plate, a support plate disposed axially opposite the cover plate and a supporting member mounted to both the cover and support plates, and a unitary radially elastic output member pivotable relative to and elastically coupled to the torque input member. The output member is disposed axially between the cover plate and the piston plate. The output member includes an output hub and a curved elastic blade configured to elastically and radially engage the supporting member and to elastically bend in the radial direction upon rotation of the cover plate with respect to the output member. The cover plate at least partially covers an axially first outer surface of the output member. The support plate partially covers an axially second outer surface of the output member.

An elevatable supporting device for bearing a display is provided. The elevatable supporting device comprises an upright, an energy storage element, and a bearing module. The upright includes a first sliding structure and a second sliding structure which is non-parallel to the first sliding structure. The energy storage element abuts against the first sliding structure and the second sliding structure and includes a first arm providing a first resistance and a second arm providing a second resistance. A first included angle is defined between the first arm and the second arm. When the energy storage element moves from the highest position to the lowest position, the first included angle decreases so that one of the first resistance and the second resistance may increase in order to maintain a total effective resistance along the first axis. Accordingly, the display may be able to stop at any position between the highest position and the lowest position.
