Lightbar device and display module thereof
A lightbar device includes a plastic frame, a back plate, a lightbar, and at least one fixing pad. At least one positioning hole is formed on the back plate. The lightbar is slidably disposed between the back plate and the plastic frame. The fixing pad includes a base, a side board, and a first clamping portion. A recession is formed at the base. The recession is used for engaging with the positioning hole so as to fix the fixing pad onto the back plate. The side board is formed at a side of the base. The first clamping portion is formed at a position of the base opposite to the side board. The first clamping portion is used for clamping a first side of the lightbar cooperatively with the side board.
1. A lightbar device comprising:
a plastic frame;
a back plate having at least one positioning hole;
a lightbar slidably disposed between the back plate and the plastic frame; and
at least one fixing pad comprising:
a base having a recession formed at a first side of the base, the recession being used for engaging with the positioning hole in a first direction so as to fix the fixing pad onto the back plate;
a side board formed at a second side of the base; and
a first clamping portion formed at a position of the base opposite to the side board, for clamping a first side of the lightbar cooperatively with the side board in a second direction different from the first direction.
2. The lightbar device of claim 1 , wherein at least one protruding portion is formed in the recession, a limiting opening is formed at a position of the positioning hole corresponding to the protruding portion, and the protruding portion is used for engaging with the limiting opening when the recession is engaged with the positioning hole.
3. The lightbar device of claim 1 , wherein a second clamping portion is formed at a position of the plastic frame corresponding to the first clamping portion, and the second clamping portion is used for clamping a second side of the lightbar cooperatively with the back plate.
4. The lightbar device of claim 3 , wherein the first clamping portion and the second clamping portion are an arc-shaped protruding structure.
5. The lightbar device of claim 1 , wherein a positioning rib is formed on the plastic frame, a positioning opening is correspondingly formed on the lightbar, and the positioning rib is used for engaging with the positioning opening so as to fix the lightbar between the back plate and the plastic frame.
6. The lightbar device of claim 1 , wherein the plastic frame has an extraction opening for replacing the lightbar.
7. The lightbar device of claim 1 , wherein a recessed portion is extensively formed at the positioning hole corresponding to a bottom of the recession.
8. The lightbar device of claim 1 , wherein the fixing pad is made of plastic, rubber, or metal material.
9. A display module comprising:
a lightbar device comprising:
a plastic frame;
a back plate having at least one positioning hole;
a lightbar slidably disposed between the back plate and the plastic frame; and
at least one fixing pad comprising:
a base having a recession formed at a first side of the base, the recession being used for engaging with the positioning hole in a first direction so as to fix the fixing pad onto the back plate;
a side board formed at a second side of the base; and
a first clamping portion formed at a position of the base opposite to the side board, for clamping a first side of the lightbar cooperatively with the side board in a second direction different from the first direction;
a panel device disposed on the lightbar device; and
an outer frame disposed on the panel device for fixing the panel device onto the lightbar device.
10. The display module of claim 9 , wherein at least one protruding portion is formed in the recession, a limiting opening is formed at a position of the positioning hole corresponding to the protruding portion, and the protruding portion is used for engaging with the limiting opening when the recession is engaged with the positioning hole.
11. The display module of claim 9 , wherein a second clamping portion is formed at a position of the plastic frame corresponding to the first clamping portion, and the second clamping portion is used for clamping a second side of the lightbar cooperatively with the back plate.
12. The display module of claim 11 , wherein the first clamping portion and the second clamping portion are an arc-shaped protruding structure.
13. The display module of claim 9 , wherein a positioning rib is formed on the plastic frame, a positioning opening is correspondingly formed on the lightbar, and the positioning rib is used for engaging with the positioning opening so as to fix the lightbar between the back plate and the plastic frame.
14. The display module of claim 9 , wherein the plastic frame has an extraction opening for replacing the lightbar.
15. The display module of claim 9 , wherein a recessed portion is extensively formed at the positioning hole corresponding to a bottom of the recession.
16. The display module of claim 9 , wherein the fixing pad is made of plastic, rubber, or metal material.
