Abstract

A frame assembly and display device are provided. The frame assembly includes a mounting member, a sliding member, a top cover and a bottom cover. The sliding member is slidably disposed on the mounting member, in which the sliding member has at least one mounting hole and at least one engaging plate. The top cover has at least one protruding lug, in which the protruding lug is accommodated in the mounting hole, and at least one portion of the protruding lug is positioned by the engaging plate. The bottom cover has at least one engaging hook, in which the engaging hook is engaged in the mounting hole.

Claims

1. A frame assembly, comprising:

a mounting member;

a sliding member slidably disposed on the mounting member, wherein the sliding member has at least one mounting hole and at least one engaging plate;

a top cover having at least one protruding lug, wherein the protruding lug is accommodated in the mounting hole, and at least one portion of the protruding lug is positioned by the engaging plate; and

a bottom cover having at least one engaging hook, wherein the engaging hook is engaged in the mounting hole.

2. The frame assembly of claim 1, wherein the protruding lug of the top cover includes a first extending portion and a first positioning portion, and the first extending portion extends along a depth direction of the mounting hole, and the first positioning portion extends along an extending direction which is vertical to the depth direction, and the first positioning portion is restrained by the engaging plate.

3. The frame assembly of claim 2, wherein the engaging plate has an engaging passageway, and the first extending portion is engaged in the engaging passageway.

4. The frame assembly of claim 2, wherein

the engaging plate includes a first engaging unit and a second engaging unit opposite to the first engaging unit, wherein an engaging passageway is defined between the first engaging unit and the second engaging unit, and the first extending portion is engaged in the engaging passageway;

and

the top cover has a first main body, wherein the protruding lug extends from one side of the first main body, and the first main body covers the first engaging unit, and the first positioning portion of the protruding lug is restrained by the second engaging unit.

5. The frame assembly of claim 1, wherein the engaging hook of the bottom cover includes a second extending portion and a second positioning portion, and the second extending portion extends along a depth direction of the mounting hole, and the second positioning portion extends along an extending direction which is vertical to the depth direction, and the second positioning portion is engaged between the bottom surface of the mounting hole and the top cover.

6. The frame assembly of claim 5, wherein

the engaging plate includes a first engaging unit and a second engaging unit opposite to the first engaging unit;

and

the bottom cover has a second main body, the engaging hook extends from one side of the second main body, wherein the second main body covers the second engaging unit.

7. The frame assembly of claim 1, wherein

the mounting member has at least one convex post;

and

the sliding member has at least one elongated hole corresponding to the convex post, wherein the convex post is set in the elongated hole, and the sliding member is slidable along an axle line, and a long axis of the elongated hole is parallel to the axle line.

8. A display device, comprising:

a back plate;

a light guide plate disposed in the back plate, wherein the light guide plate has a light-incident surface;
