Description

Middle frame integrated structure

Technical Field

The invention relates to the technical field of electronic equipment display devices, in particular to a structure of a screen middle frame of an electronic equipment display device.

Background

In the prior art, the conventional method for integrally arranging the centering frame is to arrange a through hole on the metal frame or arrange an arch head on the end of the through hole, and then fill the filling material into the through hole or the arch head of the metal frame during injection molding to form a glue pulling structure, so that the filling material is fixed on the metal frame. The method only enables the filling material to be in contact with the surface of the inner wall of the middle frame, and even if the arch head is arranged to form the rubber pulling structure, the rubber pulling structure is not firm and is easy to have the phenomena of degumming and the like. Meanwhile, the filling material generally plays a role in bearing the liquid crystal screen and the optical membrane on the display screen, and the filling material is easy to shrink in the processing process, so that the problems of deformation, wrinkling and the like of the liquid crystal screen and the optical membrane are easily caused, and the display effect of the screen is influenced.

In addition, patent reference with publication number CN 208675281U discloses a mobile phone middle frame capable of strengthening a pulling structure, which discloses that "the four corners of the middle frame body are respectively provided with at least one cylindrical through hole penetrating through the upper and lower surfaces of the middle frame body, and a rectangular notch portion communicating the inner space of the middle frame body and the cylindrical through hole is provided along the cylindrical through hole to the inner wall of the middle frame body, and the width of the rectangular notch portion is smaller than the diameter of the cylindrical through hole". This scheme design is complicated, and especially technical feature such as inside lugs, boss and arc breach is too meticulous, and is higher to production technology requirement, and the equipment process is comparatively numerous, is unfavorable for large-scale production, therefore the practicality is not enough, is difficult to large-scale production. And the appearance is not pleasing to the eye, is difficult to form the high filler material layer of density at the center surface more, is unfavorable for the further application of center, is difficult to popularize to other screen schemes and uses.

This scheme design is complicated, and especially technical feature such as inside lugs, boss and arc breach is too meticulous, and is higher to production technology requirement, and the equipment process is comparatively numerous, is unfavorable for large-scale production, therefore the practicality is not enough, is difficult to large-scale production. And the appearance is not pleasing to the eye, is difficult to form the high filler material layer of density at the center surface more, is unfavorable for the further application of center, is difficult to popularize to other screen schemes and uses.

Example 1

As shown in FIG. 2, the integrated structure of the middle frame comprises the middle frame, wherein a protruding part is arranged on the outer surface of the middle frame. The surface of the middle frame of the technical scheme is provided with a through hole corresponding to the protruding part. Wherein at least one group of through holes and corresponding protruding parts are provided.

The preferred material of the middle frame in the technical scheme is metal or alloy material in the prior art.

According to the technical scheme, the protruding portion and the through hole are formed by processing the middle frame through the stamping process, the stamping process is a mature and convenient processing method, the protruding portion is formed by stamping one part of the original middle frame, the through hole is formed in the original position, the design and installation of parts are not needed, and the production steps are greatly simplified.

The protruding part of the technical scheme is preferably in an arch structure or adopts a hollow-out process. Preferably, the height of the protrusion is set to be between 1/4 and 3/4 of the thickness of the filling material, so that the physical hardness of the protrusion can be effectively ensured.

Example 2

As shown in fig. 4, a middle frame integrated structure includes a filling material and the middle frame of embodiment 1, the filling material covers the middle frame and fills the hole of the protruding portion, so as to ensure that the filling material can completely cover and fill the protruding portion, and the hole of the protruding portion and the filling material form a hook structure, thereby forming a stable middle frame integration.

The filling material of the technical scheme is composed of high molecular synthetic resin, namely plastic commonly known in the technical field. Mainly adopts PE/PP/PVC/PS/ABS/PMMA/POM/PC/PA and other raw materials. Additives such as plasticizers, stabilizers, flame retardants, lubricants, colorants, etc., plastic (flexible) materials formed by processing, or rigid materials formed by curing and crosslinking, etc., may be appropriately added during the processing. The processing technology adopts a heating mode to melt, a pressurizing mode to flow and a cooling mode to solidify and form a required shape.

As shown in fig. 3-4, the filling material of the present invention covers the surface of the middle frame to form a filling material frame having the same shape as the middle frame. The filling material frame is used as a display intermediate material to play a role in bearing the liquid crystal screen and the optical film, and in order to ensure the display effect, the filling material frame is required to ensure not only certain hardness but also stability in shape. The filling material made of high molecular polymer usually deforms after being processed and cooled, which can cause abnormal sequencing of liquid crystals in the liquid crystal screen or wrinkles of the optical diaphragm close to the filling material, and thus the display effect of the screen is affected. Therefore, the filling material on the surface of the middle frame is arranged into a plurality of sections of Z-shaped fractures, and gaps reserved between the fractures can effectively avoid the problems and improve the quality of products. Moreover, the Z-shaped design of the fracture is beautiful and elegant, the longer fracture is also helpful to prevent external dust from entering and internal light from being exposed,
