Abstract

A panel positioning assembly, is provided in embodiments of the disclosure, the panel positioning assembly which is used for a panel comprising: a side frame at least partially provided at a periphery of the panel; and a plurality of positioners detachably provided on the side frame and configured to position the panel; and a backlight module and a display device are provided in embodiments of the disclosure, too.

First claim

What is claimed is:

1. A panel positioning assembly which is used for a panel, comprising:
a side frame at least partially provided at a periphery of the panel; and
positioners detachably provided on the side frame and configured to position the panel;
wherein the positioners are provided respectively at corners of the side frame which function as junctions of adjacent sides of the side frame abutting against each other, respectively;
wherein each of the positioners is in a form of L shape, and is provided at a junction of two adjacent sides of the side frame corresponding thereto;
wherein clamping components for connecting with the positioners respectively are provided at the corners of the side frame, respectively;
wherein at least one corner of the corners of the side frame comprises a first side portion and a second side portion abutting against each other, with a first baffle plate being provided at an outer side of the first side portion, and a second baffle plate being provided at an outer side of the second side portion, the first baffle plate and the second baffle plate functioning as the clamping components respectively; and
wherein at least one of the first baffle plate and the second baffle plate extends perpendicular to a respective one of the first side portion and the second portion, at the outer side of the latter.

2. The panel positioning assembly according to claim 1 , wherein the side frame is provided with four sides, on each of which a corresponding one of the positioners is provided.

3. The panel positioning assembly according to claim 1 , wherein at least one positioner of the positioners comprises a first connection block and a second connection block.

4. The panel positioning assembly according to claim 3 , wherein the first connection block and the second connection block differs from each other in size.

5. The panel positioning assembly according to claim 3 , wherein the first connection block and the second connection block are provided separately and connected with each other.

6. The panel positioning assembly according to claim 5 , wherein a notch which is recessed inwards the side frame is formed at a junction of the first connection block and the second connection block of the at least one positioner of the positioners, on inside walls of the at least one positioner which interface with each other and both face towards an inner side of the side frame.

7. The panel positioning assembly according to claim 3 , wherein the first connection block and the second connection block are formed integrally into one piece.

8. The panel positioning assembly according to claim 1 , wherein a top portion of the first baffle plate extends away from the first side portion in a direction perpendicular to the first side portion and bends inwards the side frame to form a first shielding portion, and
a top portion of the second baffle plate extends away from the second side portion in a direction perpendicular to the second side portion and bends inwards the side frame to form a second shielding portion.

9. The panel positioning assembly according to claim 8 , wherein a first groove configured to accommodate the first baffle plate and a second groove configured to accommodate the second baffle plate are provided on each of the positioners respectively, the first groove extending from the outer side of the first side portion to a top side of the first side portion, and/or the second groove extending from the outer side of the second side portion to a top side of the second side portion; and
the first groove and the second groove are further configured to align an outer edge of the first baffle plate with an outer edge of the first side portion to be flush with each other, to align a top edge of the first baffle plate with a top edge of the first side portion to be flush with each other, respectively, and/or to align an outer edge of the second baffle plate with an outer edge of the second side portion to be flush with each other, to align a top edge of the second baffle plate with a top edge of the second side portion to be flush with each other, respectively, in response to the first groove accommodating the first baffle plate which has the first shielding portion and/or the second groove accommodating the second baffle plate which has the second shielding portion respectively.

10. The panel positioning assembly according to claim 1 , wherein a first groove configured to accommodate the first baffle plate and a second groove configured to accommodate the second baffle plate are provided on each of the positioners respectively; and
the first groove and the second groove are further configured to align an outer edge of the first baffle plate with an outer edge of the first side portion to be flush with each other, and to align an outer edge of the second baffle plate with an outer edge of the second side portion to be flush with each other, in response to the first groove accommodating the first baffle plate and the second groove accommodating the second baffle plate respectively.

11. A backlight module, comprising:
a backlight source; and
the panel positioning assembly according to claim 1 .

12. The backlight module according to claim 11 , wherein the backlight module further comprises a back plate, on which the side frame of the panel positioning assembly is fixed.

13. A display device, comprising:
the backlight module according to claim 12 ; and
the panel, on a back side of which the backlight source of the backlight module is provided.
