Abstract

The present disclosure provides a hinge assembly including a first hinge body, a second hinge body, a movable block, a pushing block, a cushion block, and a pivot. The pivot is fixedly mounted to the first hinge body and is provided with a planar recess on a shaft body surface thereof. The movable block and the second hinge body are detachably connected to each other. The movable block is pivotally connected with the first hinge body via the pivot. A top surface of the movable block abuts against the first hinge body. The pushing block includes a first inclined surface. The cushion block includes a second inclined surface. A top surface of the pushing block abuts against the movable block. The pushing block slidably abuts against the shaft body of the pivot. The hinge assembly according to the present disclosure realizes seamless lifting of the hinge.

First claim

The invention claimed is:

1. A hinge assembly, comprising:
a first hinge body;
a second hinge body;
a pivot fixedly mounted to a side of the first hinge body and provided with a planar recess on a shaft body surface thereof;
a movable block detachably connected with the second hinge body and pivotally connected with the first hinge body via the pivot, wherein a top surface of the movable block is configured to abut the first hinge body;
a pushing block comprising a first inclined surface and configured to slidably abut the shaft body of the pivot, wherein a top surface of the pushing block is configured to abut the movable block; and
a cushion block arranged on the second hinge body and comprising a second inclined surface,
wherein, the pushing block is configured to
in a case where the first hinge body brings the pivot to rotate from a first position to a second position, switch from a first status to a second status, slide upward along the second inclined surface of the cushion block, and bring the movable block and the first hinge body to move upward with respect to the second hinge body, the first status being a status where the pushing block is configured to abut the planar recess of the pivot, the second status being a status where the pushing block is configured to abut a rotary surface of the pivot on either side of the planar recess, and
in a case where the first hinge body brings the pivot to rotate from the second position to the first position, switch from the second status to the first status, slide downward along the second inclined surface, and bring the movable block and the first hinge body to move downward with respect to the second hinge body.

2. The hinge assembly according to claim 1 , wherein the movable block comprises a sleeve for pivotally connecting with the pivot and a first snap engagement portion formed integrally with the sleeve, and a second snap engagement portion is provided on a side of the second hinge body for snap engagement with the first snap engagement portion.

3. The hinge assembly according to claim 2 , wherein the first snap engagement portion is vertical ribs of a double-boss structure provided parallel with an axial direction of the sleeve, and the second snap engagement portion is a vertical slot adaptive for engagement with the vertical ribs.

4. The hinge assembly according to claim 3 , wherein a first housing groove is provided in the movable block and is configured to communicate with the planar recess of the pivot,
a second housing groove is provided in the second hinge body, and
the first and second housing grooves are provided opposite to each other and configured as a working cavity for cooperation of the cushion bock and the pushing block.

5. The hinge assembly according to claim 4 , wherein the pushing block and the cushion block are arranged vertically in the working cavity, the first inclined surface and the second inclined surface are configured to fit to each other, and the cushion block is fixed in the second housing groove.

6. The hinge assembly according to claim 4 , wherein the first housing groove is a through groove passing between the vertical ribs of the movable block and through a sleeve wall of the sleeve,
the pushing block is arranged in the through groove with the top surface thereof abutting against a top surface of the through groove, and
the second housing groove is a part of the vertical slot.

7. The hinge assembly according to claim 6 , wherein a positioning slot is provided depressing in a bottom surface of the vertical slot, and the cushion block is fixed in the positioning slot.

8. The hinge assembly according to claim 1 , wherein a contacting surface of the pushing block slidably abutting the shaft body of the pivot is a rounded surface.

9. The hinge assembly according to claim 1 , wherein a mounting groove for mounting the movable block is provided on a side of the first hinge body, the movable block is configured to abut against a bottom surface of the mounting groove, and an abutting surface of the movable block is a rounded surface.

10. The hinge assembly according to claim 9 , wherein a crash pad is provided between the movable block and the bottom surface of the mounting groove.

11. The hinge assembly according to claim 3 , wherein a blocking piece is provided at a top of the vertical slot.
