Abstract

A display module holding frame and method of manufacturing same include the steps of: first, providing a support frame which includes an installation frame to hold a display module, two installation portions to hold two hinge structures, an installation space formed within the installation frame, a coupling space formed between the two installation portions and a wiring passage communicating with the installation space and the coupling space; next, threading a signal wire through the wiring passage; finally, forming a rubber protective layer on the surface of the support frame via an injection process. The rubber protective layer has a holding portion to fix the signal wire in the wiring passage. The display module holding frame thus formed provides a structure to securely hold the signal wire without moving freely.

Claims

1. A method for manufacturing a display module holding frame located in an electronic device which includes a base and two hinge structures to pivotally couple with the base and the display module holding frame, comprising the steps of:

providing a support frame which includes an installation frame to hold a display module, two installation portions to hold the two hinge structures, an installation space formed within the installation frame, a coupling space formed between the two installation portions and located outside the installation frame, and two wiring passages each running through the installation frame and one of the installation portions and communicating with the installation space and the coupling space;

threading two signal wires through the two wiring passages respectively to couple with the support frame; and

forming a rubber protective layer on the surface of the installation frame that includes a buffer portion bonded between the surface of the installation frame and the display module and two portions held in the two wiring passages to fix the two signal wires respectively so that the two signal wires and the installation frame form a positioning relationship.

2. The method of claim 1, wherein the step of forming the rubber protective layer on the surface of the installation frame further includes the steps of:

disposing the coupled support frame and the two signal wires into a mold for holding a rubber material respectively, the mold including a male mold and a female mold coupled together to hold the coupled support frame and the two signal wires; and

injecting the rubber material to the surface of the installation frame to form the buffer portion and fill the two wiring passages to encase the two signal wires to form the two holding portions.

3. The method of claim 1, wherein the two hinge structures respectively include a fastening portion fastened to the base and a pintle portion located in one of the two installation portions to rotate against the fastening portion.

4. The method of claim 3 further including a step of threading the two signal wires through the two pintle portions respectively that is performed after the step of providing the support frame, each of the pintle portions including an axial aperture communicating with one of the two wiring passages to allow one of the two signal wires to thread through.

5. The method of claim 1 further including a step of assembling the installation frame that is performed before the step of providing the support frame, the installation frame including a side frame to hold the display module and a bottom frame connecting to the installation portions to form the installation space.

6. The method of claim 1, wherein the signal wire includes a signal transmission section encased by the holding portion and two connection ports located at two ends of the signal transmission section.

7. A display module holding frame located in an electronic device which includes a base and two hinge structures to pivotally couple with the base and the display module holding frame such that the display module holding frame is rotatable against the base, comprising:

a support frame which includes an installation frame to hold a display module, two installation portions connected to the installation frame to hold the two hinge structures, an installation space formed within the installation frame to hold the display module, a coupling space formed between the two installation portions and located outside the installation frame, and two wiring passages each running through the installation frame and one of the two installation portions and communicating with the installation space and the coupling space and threaded through by two signal wires respectively; and

a rubber protective layer which is located on the support frame and includes a buffer portion bonded between the surface of the installation frame and the display module and two holding portions held in the two the wiring passages to fix the two signal wires respectively so that the two signal wires and the installation frame form a positioning relationship.

8. The display module holding frame of claim 7, wherein the two hinge structures respectively include a fastening portion fastened to the base and a pintle portion located in one of the two installation portions to rotate against the fastening portion.

9. The display module holding frame of claim 8, wherein each of the pintle portions includes an axial aperture communicating with one of the two wiring passages.

10. The display module holding frame of claim 7, wherein the installation frame includes a side frame to hold the display module and a bottom frame connecting to the installation portions and coupling with the side frame to form the installation space.

11. The display module holding frame of claim 7, wherein each of the signal wires includes a signal transmission section encased by one of the two holding portions and two connection ports located at two ends of the signal transmission section.
