Abstract: A quick connection device includes: a sleeved connected with a first member and a moving assembly movably disposed in the sleeve. The moving assembly includes: a support base disposed in the sleeve; a mounting base, configured to be connected with a second member and movable along the axial direction relative to the support base; a locking member, fixed to the mounting base and configured to cooperate with the support base to achieve a locking state and an unlocking state and restrict movement of the mounting base towards a direction away from the support base when in the locking state and allow movement of the mounting base towards a direction away from the support base when in the unlocking state; and a limiting member, configured to restrict movement of the moving assembly in the sleeve when the mounting base is in an initial position corresponding to the locking state.

Abstract: A haptic feedback apparatus is described. The haptic feedback apparatus comprises a headpiece that conforms to a neurocranium of a user and a haptic processor. The headpiece comprises left and right haptic actuators. The haptic processor is configured to process an input signal and activate the left and right haptic actuators according to the input signal. The left and right haptic actuators are located on the headpiece to abut the neurocranium of the user when the headpiece is worn by the user. The left and right haptic actuators provide haptic feedback to the user via the neurocranium upon activation by the haptic processor.

Abstract: A vibration unit and a head-mounted display device are provided. The vibration unit includes a vibration motor, a vibration motor mount, a pressing guide, a main frame and an elastic member, the pressing guide including a pressing rod and a pressing plate, and a through hole being provided in either end of the main frame. The vibration motor is in the vibration motor mount fixedly connected to a first surface of the pressing plate; a second surface of the pressing plate abuts against a first end of the pressing rod, and a second end of the pressing rod passes through the through hole and is moveably connected to the main frame; the elastic member is around the pressing rod and is between the pressing plate and the main frame; and the main frame includes a connecting base configured to be connected to the head-mounted display device.
