Abstract

A damping device is applicable to a hinge. The damping device includes a housing, a damper, an abutting member and an adjusting member. The damper is arranged on the housing. The damper includes a first movable member and a second movable member movable relative to each other. The abutting member is configured to abut against the second movable member of the damper. The adjusting member is movable relative to the housing. When the adjusting member is moved to a first position relative to the housing, the adjusting member abuts against the first movable member of the damper. When the adjusting member is moved to a second position relative to the housing, the adjusting member does not abut against the first movable member of the damper.

Claims

1. A damping device comprising:

a housing;

a damper arranged on the housing, the damper comprising a first movable member and a second movable member longitudinally movable relative to each other;

an abutting member configured to abut against the second movable member of the damper; and

an adjusting member transversely movable relative to the housing, wherein the adjusting member has a first hole, a second hole, and at least one guiding section located between the first hole and the second hole, the adjusting member is connected to the housing by a mounting member passing through one of the first hole and the second hole, said mounting member is selectively positionable into one of said first hole and said second hole through the guiding section;

wherein when the mounting member passes through the first hole of the adjusting member, the adjusting member abuts against the first movable member of the damper;

wherein when the mounting member passes through the second hole of the adjusting member, the adjusting member does not abut against the first movable member of the damper.

2. The damping device of claim 1, wherein the housing has a longitudinal passage configured to accommodate the damper.

3. The damping device of claim 1, wherein the housing comprises an extension part, and the adjusting member is movably installed on the extension part.

4. The damping device of claim 3, wherein the adjusting member comprises a main body and a flexible part connected to the main body, and the main body of the adjusting member has a transverse guiding feature defined by the first hole, the second hole, and the guiding section for allowing the adjusting member to be transversely movable relative to housing.

5. The damping device of claim 1, wherein the first movable member of the damper is a cylinder and the second movable member of the damper is a piston rod.

6. A hinge comprising:

a first component;

a second component pivotally connected to the first component;

an elastic member configured to provide an elastic force when the second component is opened or closed relative to the first component;

a linkage member configured to move when the second component is rotated relative to the first component; and

a damping device installed on one of the first component and the second component, the damping device comprising;

a housing;

a damper arranged on the housing, the damper comprising a first movable member and a second movable member longitudinally movable relative to each other;

an abutting member configured to abut against the second movable member of the damper for allowing the first movable member to be moved between a first predetermined position and a second predetermined position relative to the second movable member; and

an adjusting member movable relative to the housing;

wherein the housing has a longitudinal passage configured to accommodate the damper, and an extension part, the adjusting member is movably installed on the extension part;

wherein the adjusting member comprises a main body and a flexible part connected to the main body, and the main body of the adjusting member has a transverse guiding feature for allowing the adjusting member to be transversely movable relative to the housing;

wherein, the transverse guiding feature comprises a first hole, a second hole, and at least one guiding section located between the first hole and the second hole, the hinge further comprises a mounting member connected to the extension part of the housing and passing through one of the first hole and the second hole, said mounting member is selectively positionable into one of said first hole and said second hole through the guiding section;

wherein when the mounting member passes through the first hole of the adjusting member, the adjusting member abuts against the first movable member of the damper, such that the first movable member is located at the first predetermined position;

wherein when the mounting member passes through the second hole of the adjusting member, the adjusting member does not abut against the first movable member of the damper, such that the first movable member is located at the second predetermined position, and when the second component is moved to switch from an open state to a close state relative to the first component, the linkage member pushes the first movable member of the damper from the second predetermined position to the first predetermined position for providing damping effect.

7. A hinge comprising:

a first component;

a second component pivotally connected to the first component;

an elastic member configured to provide an elastic force when the second component is opened or closed relative to the first component;

a linkage member configured to move when the second component is rotated relative to the first component;

a damping device installed on one of the first component and the second component, the damping device comprising;

a housing;

a damper arranged on the housing, the damper comprising a first movable member and a second movable member longitudinally movable relative to each other, the first movable member comprising an abutting part;

an abutting member configured to abut against the second movable member of the damper for allowing the first movable member to be moved between a first predetermined position and a second predetermined position relative to the second movable member; and

an adjusting member movable relative to the housing, the adjusting member comprising a main body and a flexible part connected to the main body, wherein the main body has a transverse guiding feature for allowing the adjusting member to be transversely movable relative to the housing, the transverse guiding feature comprises a first hole, a second hole, and at least one guiding section located between the first hole and the second hole; and

a mounting member connected to the housing and passing through one of the first hole and the second hole of the adjusting member said mounting member is selectively positionable into one of said first hole and said second hole through the guiding section;

wherein when the first movable member of the damper is located at the second predetermined position relative to the second movable member and the mounting member passes through the first hole of the adjusting member, the flexible part of the adjusting member abuts against the first movable member of the damper;

wherein when the second component is moved to switch from an open state to a close state relative to the first component, the linkage member pushes the first movable member of the damper from the second predetermined position to the first predetermined position for allowing the flexible part of the adjusting member to abut against the abutting part, in order to hold the first movable member at the first predetermined position relative to the second movable member.
