Abstract

A backlight rubber-iron structure and a method of manufacturing the same, a backlight and a display device are disclosed. The backlight rubber-iron structure includes a back plate and a rubber frame. The back plate has a bottom plate and a plurality of folded edges. A plurality of recesses is provided at joints of the bottom plate and the folded edges. Each recess is provided with a connecting hole and a blocking surface. The rubber frame includes a rubber frame body, a connector corresponding to the connecting hole in a one-to-one manner and a blocker corresponding to the recess in a one-to-one manner. The rubber frame body, the connector and the blocker have an integrated structure. The rubber frame body is in the backlight assembly receiving groove. Each blocker is in the corresponding recess and is clamped with the recess by abutting the blocking surface at the bottom of the recess.

First claim

What is claimed is:

1. A backlight rubber-iron structure, comprising: a back plate and a rubber frame;
wherein the back plate comprises:
a bottom plate;
a plurality of folded edges;
a backlight assembly receiving groove defined by the bottom plate and the folded edges;
a plurality of recesses defined at joints of the bottom plate and the plurality of folded edges, each of the plurality of recesses facing away from the backlight assembly receiving groove;
a connecting hole defined through each recess of the plurality of recesses and communicating the each recess with the backlight assembly receiving groove; and
a blocking surface defined by at least part of a bottom of each recess of the plurality of recesses located at a periphery of the connecting hole of the each recess, wherein the blocking surface is facing away from the backlight assembly receiving groove;
wherein the rubber frame comprises a rubber frame body, a connector corresponding to the connecting hole in a one-to-one manner, and a blocker corresponding to the recess in a one-to-one manner and connected with the connector; the rubber frame body, the connector and the blocker have an integrated structure;
wherein the rubber frame body is in the backlight assembly receiving groove; the connector extends through the corresponding connecting hole; and
the blocker is in the corresponding recess and is clamped with the corresponding recess by abutting against the blocking surface at the bottom of the corresponding recess.

2. The backlight rubber-iron structure according to claim 1 , wherein a quantity of the plurality of recesses at the joints of the bottom plate and the folded edges in the back plate is 13-15.

3. The backlight rubber-iron structure according to claim 1 , wherein each recess of the plurality of recesses has a rectangular structure, and a long side direction of the rectangular structure is parallel to an extending direction of the folded edge where the rectangular structure is located.

4. The backlight rubber-iron structure according to claim 1 , wherein a cross section of each recess of the plurality of recesses is arc-like or trapezoidal with a width increasing in a direction away from the bottom of the each recess.

5. The backlight rubber-iron structure according to claim 1 , wherein a distance, from a side of the bottom of a recess of the plurality of recesses facing away from the recess, to the rubber frame body, is 0.5 mm-1 mm.

6. The backlight rubber-iron structure according to claim 1 , wherein the blocker and the connector define a T-shaped.

7. The backlight rubber-iron structure according to claim 1 , wherein a surface of the blocker facing away from backlight assembly receiving groove is flush with the corresponding folded edge.

8. A backlight, comprising: the backlight rubber-iron structure according to claim 1 .

9. A display device, comprising: the backlight according to claim 8 .

10. A method of manufacturing the backlight rubber-iron structure according to claim 1 , comprising:
forming a back plate which comprises a bottom plate, a plurality of folded edges, a backlight assembly receiving groove defined by the bottom plate and the folded edges, a plurality of recesses defined at joints of the bottom plate and the plurality of folded edges with each of the plurality of recesses facing away from the backlight assembly receiving groove, a connecting hole defined through each recess of the plurality of recesses and communicating the each recess with the backlight assembly receiving groove, and a blocking surface defined by at least part of a bottom of each recess of the plurality of recesses located at a periphery of the connecting hole of the each recess, wherein the blocking surface is facing away from the backlight assembly receiving groove;
forming a rubber frame which comprises a rubber frame body and an extension portion formed on the rubber frame body and corresponding to the connecting hole in a one-to-one manner;
disposing the rubber frame body into the backlight assembly receiving groove and extending the extension portion through the corresponding connecting hole; and
forming a blocker and a connector by performing a heat-deforming process on a part of the extension portion extending through the connecting hole to outside of the backlight assembly receiving groove.

11. The method according to claim 10 , wherein the forming the blocker and the connector by performing the heat-deforming process on the part of the extension portion extending through the connecting hole to outside of the backlight assembly receiving groove comprises:
using a heating apparatus to heat and soften the part of the extension portion extending through the connecting hole to outside of the backlight assembly receiving groove;
forming the blocker by extending the softened part of the extension portion along a direction of the bottom surface of the recess until abutting against at least part of a periphery part of the connection hole; and
form the connector with an un-deformed part of the extension portion located in the connecting hole.

12. The method according to claim 11 , wherein a surface of the blocker facing away from backlight assembly receiving groove is flush with the folded edge.
