Abstract

Provided is a flexible screen mechanism of a mobile terminal, the flexible screen mechanism comprising a flexible screen, wherein a bendable sheet capable of being restored to being straight, by means of depending on elasticity, is attached to the back of the flexible screen. The sheet is provided, corresponding to a bent part of the flexible screen mechanism when the mobile terminal is folded, with at least one of the following structures: (1) a plurality of arranged or dispersed holes; and (2) a plurality of arranged tongue pieces, wherein a length direction of roots of the tongue pieces is the same as a width direction of the flexible screen. The flexible screen mechanism can prevent a screen from being damaged under the stress of stretching, while the strength of the screen is improved, and under the conditions of improving the strength, the stress borne by the screen and an elastic force generated when the screen is folded are reduced, such that the strength and the flexibility of the screen are both taken into account.

Description

Flexible screen mechanism of mobile terminal

Technical field

The invention relates to a flexible screen mobile terminal, in particular to a flexible screen mechanism of the mobile terminal.

Background technique

In the current flexible screen mobile terminal, the flexible screen needs to have considerable strength to participate in the opening and closing state change movement of the mobile terminal and resist tensile force, but this will cause the flexible screen to be difficult to bend.

Summary of the invention

The technical problem to be solved by the present invention is to provide a flexible screen mechanism of a mobile terminal, which can give consideration to both strength and flexibility. To this end, the present invention adopts the following technical solutions:

A flexible screen mechanism of a mobile terminal, including a flexible screen, is characterized in that a sheet capable of bending and restoring upright by elasticity is pasted on the back of the flexible screen, and the sheet is corresponding to the bending part of the flexible screen mechanism when the mobile terminal is closed At least one of the following structures is provided:

(1) Multiple holes arranged or scattered;

(2) A plurality of tongues are arranged, and the length direction of the root of the tongue is consistent with the width direction of the flexible screen.

Further, the hole is a long hole whose length direction is consistent with the width direction of the flexible screen.

Further, the tongue piece is formed by cutting a sheet with arc-shaped slits or folded-line slits, or by punching holes at both ends of the long hole. Furthermore, holes are punched at both ends of the seam.

The tongue piece is one or more of rectangular tongue piece, trapezoidal tongue piece and arc tongue piece.

A tongue is provided near the position where the flexible screen mechanism starts to bend when the mobile terminal is closed.

At least part of the head of the tongue is close to the midline of the bending part of the flexible screen.

Further, the arranged multiple tongues are symmetrically arranged with the center line of the bending part of the flexible screen as the symmetry line.

Further, the sheet is a thin steel sheet.

Due to the technical solution of the present invention, the present invention can increase the strength of the screen to avoid damage caused by tensile force, and under the condition of increasing the strength, reduce the stress on the screen and the rebound force when closed, taking into account the strength and strength of the screen. Flexibility.

detailed description

Refer to the attached drawings. The flexible screen mechanism of the mobile terminal provided by the present invention includes a flexible screen 1, and a thin sheet 2 that can be bent and restored to be straight by elasticity is pasted on the back of the flexible screen 1, and the thin sheet 2 is made of thin steel.

The mobile terminal may be an outer flexible screen mobile terminal or an inner flexible screen mobile terminal, and the thin steel sheet 2 is provided with at least one of the following structures at the bending portion of the flexible screen mechanism when the mobile terminal is closed:

(1) Multiple holes arranged;

The plurality of holes can be arranged in rows to rows and columns, or staggered, or scattered irregularly. The shape of the holes can be round holes, square holes, long holes, etc., which can ensure that they can withstand a certain external force in the length direction. To ensure the strength, at the same time, it can improve the bending performance when bending.

The plurality of holes are preferably long holes whose length direction is consistent with the width direction of the flexible screen, and the preferred arrangement is row-to-row row arrangement or staggered arrangement. As shown in Figure 7, round holes 340 with a diameter larger than the width of the long hole 34 are also punched at both ends of the long hole (or called a slit) 34 (or in the middle). In this way, two circles The thin steel sheet between the holes 340 also forms a short tongue 341.

In addition to the above method of forming the tongue. The tongue piece is formed by cutting an arc-shaped slit or a folded line-shaped slit from a thin sheet. Preferably, round holes 6 may be punched at both ends of the slit (see Figures 4, 5, 6). As shown in Figure 4, the tongue can be a rectangular tongue 31; as shown in Figure 5, the tongue can be a trapezoidal tongue 32; as shown in Figure 6, the tongue can be an arc tongue. 33.

The round hole 340 and the round hole 6 can reduce the stress at the two ends of the long hole 340 and the slit, and prevent the sheet from being damaged.

The arrangement of the tongues can also be row to row column to column arrangement, or staggered arrangement. Preferably, a tongue is provided at a position close to the bending position of the flexible screen mechanism when the mobile terminal is closed (see Figures 4, 5 and 6), that is, the root 4 of the tongue is close to the bending starting position.

More preferably, at least part of the head 5 of the tongue is close to the midline of the bending part of the flexible screen (see Figures 4, 5, and 6).

More preferably, the arranged multiple tongues are symmetrically arranged with the midline of the bending part of the flexible screen as the symmetry line (see Figures 4, 5, 6).

In FIG. 1, the reference numeral 100 is the flexible screen mechanism of the present invention, the reference numeral 201 is the middle structure of the hinge, and the reference numeral 202 is the left side casing and the right side casing of the flexible screen mechanism. In FIG. 2, the reference numeral 203 is the flexible screen support plate on the casing, and the reference numeral 204 is the flexible screen elastic support sheet corresponding to the tongue.

The above are only specific embodiments of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art in the field of the present invention are all covered by the protection scope of the present invention. Among.
