Referring to <FIG>, <FIG>, <FIG> is schematic diagram showing a display device in a collapsed state of the first embodiment, <FIG> is schematic diagram showing the display device in an extended state of the first embodiment, and <FIG> is a cross-sectional view of the display device of the first embodiment.

A display device <NUM> includes a frame <NUM> and a flexible screen <NUM>. A width of the frame <NUM> is adjustable. The flexible screen <NUM> is installed on the frame <NUM>, and a width of the flexible screen <NUM> may change as the width of the frame changes.

As shown in <FIG>, which is a schematic diagram of the frame of the first embodiment.

The frame <NUM> includes a case <NUM>, a first bracket <NUM>, and a second bracket <NUM>.

The case <NUM> is provided with a plurality sliding chutes <NUM> parallel to each other. Two ends of each sliding chutes <NUM> include a first chute mouth <NUM> and a second chute mouth <NUM>. A direction of the openings of the first chute mouth <NUM> and the second chute mouth <NUM> is a width adjustment direction of the frame <NUM>.

The first bracket <NUM> includes a first sliding block <NUM> and a first box <NUM>. The first sliding block <NUM> is an elongated sliding block, one end of which is connected to one side of the first box <NUM>, and the other end of which is slidably inserted into the sliding chute <NUM> through the first chute mouth <NUM>. In order to make the first sliding block <NUM> sliding smoothly in the corresponding sliding chute <NUM>, distances between two adjacent first sliding blocks <NUM> are equal, and the two adjacent first sliding blocks <NUM> are separated by at least one sliding chute <NUM>.

The first sliding block <NUM> is connected to the side of the first box <NUM>. When the first box <NUM> moves away from the case <NUM>, the first sliding block <NUM> slides in a direction toward the first chute mouth <NUM> of the sliding chutes <NUM>. A brake locking mechanism is provided between the first sliding block <NUM> and the corresponding sliding chute <NUM> to limit a distance that the first sliding block <NUM> slides out of the sliding chute <NUM> and a position of the first sliding block <NUM> so that it is in a stable state.

Referring to <FIG> is a schematic view of a flexible lock in a braking position of the first embodiment, <FIG> is a schematic view of a flexible lock in a return position of the first embodiment, and <FIG> is a schematic view of a flexible lock in a retracted position of the first embodiment.

In this embodiment, the flexible lock <NUM> serves as a braking device of first sliding block <NUM> and sliding chute <NUM>. Specifically, the flexible lock <NUM> includes a lock tongue <NUM> and a latch <NUM>. The lock tongue <NUM> is a flexible lock tongue and is elastically arranged inside the first sliding block <NUM>. A shape of the lock tongue <NUM> is a fan-shaped protruding structure, including a plane <NUM> and a curved surface <NUM>. When the lock tongue <NUM> and the latch <NUM> are "misaligned", the lock tongue <NUM> overcomes an elastic force and is completely disposed on an inside of the first sliding block <NUM>. One side of the curved surface <NUM> of the lock tongue <NUM> faces the sliding chute <NUM> and is always tangent to an inner wall of the sliding chute <NUM>. When the lock tongue <NUM> and the latch <NUM> face each other, the lock tongue <NUM> pops out from the inside of the first sliding block <NUM>, and one side of the plane <NUM> of the lock tongue <NUM> pops out from the inside of the first sliding block <NUM> and abuts a side wall of the latch <NUM>, thereby achieving a purpose of braking the first sliding block <NUM>.

A relative position of the lock tongue <NUM> and the latch <NUM> changes as the first sliding block <NUM> slides on the sliding chute <NUM>. When the first sliding block <NUM> moves back from the braking position, a side wall of the latch <NUM> away from the plane <NUM> abuts the curved surface <NUM>. Due to a curvature of the curved surface <NUM>, the lock tongue <NUM> will be retracted into the first sliding block <NUM> under an external force of the latch <NUM> to overcome an elastic modulus.

The latch <NUM> is located at the sliding chute <NUM> near the first chute mouth <NUM>. In order to ensure that the first sliding block <NUM> can slide freely within the sliding chute <NUM>, there is a safe distance between the latch <NUM> and the first chute mouth <NUM>, thereby preventing the first sliding block <NUM> from completely separating from the sliding chute <NUM> during the sliding process.

The first box <NUM> includes a first opening <NUM> and a first chamber <NUM> corresponding to the first opening <NUM>. An outer wall of the first box <NUM> is fixedly connected to the first sliding block <NUM>, so that a position of the first box <NUM> relative to the first chute mouth <NUM> can change as the first sliding block <NUM> moves within the sliding chute <NUM>.

The first bracket <NUM> also includes a first scroll <NUM>. The first scroll <NUM> is rotatably connected to the first chamber <NUM>. Specifically, both ends of an axial of the first scroll <NUM> are rotatably connected to side walls of the first chamber <NUM> corresponding to the first chute mouth <NUM>. There is a gap between an outer wall of the first scroll <NUM> and an inner wall of the first chamber <NUM>.

The flexible screen <NUM> includes a central display area <NUM>, a first extension area <NUM>, and a second extension area <NUM>.

The central display area <NUM> is disposed directly above the case <NUM>. In an embodiment of the present disclosure, since the sliding chute <NUM> adopts a U-shaped sliding chute, that is, the sliding chute <NUM> has an opening <NUM> in addition to the first chute mouth <NUM> and the second chute mouth <NUM>. For ease of processing, a direction of the opening <NUM> is a direct direction when a user uses the display device <NUM>, that is, the case <NUM> is near the central display area <NUM>.

As shown in <FIG>, which is a side view of the display device of the first embodiment. The central display area <NUM> also includes a first side <NUM> and a second side <NUM>. The first side <NUM> is connected to one end of the first extension area <NUM>. The connection between the first extension area <NUM> and the first side <NUM> is always under tension. The second side <NUM> is connected to one end of the second extension area <NUM>. The connection between the second extension area <NUM> and the second side <NUM> is always under tension, and the central display area <NUM> is always under tension.

One end of the first extension area <NUM> away from the first side <NUM> passes through the first opening <NUM> and is spirally sleeved on an outer wall of the first scroll <NUM> and connected to the outer wall of the first scroll <NUM>. When a rotation direction of the scroll <NUM> faces away from the case <NUM>, the first extension area <NUM> spirals away from an inside of the first chamber <NUM> and gradually flattens on the first sliding block <NUM> exposed outside the sliding chute <NUM> until the first sliding block <NUM> reaches a braking distance. When the rotation direction of the scroll <NUM> is toward the case <NUM>, the first extension area <NUM> is spirally sleeved on the scroll <NUM> with the rotation direction of the scroll <NUM> and placed in the first chamber <NUM>.

The second bracket <NUM> includes a second sliding block <NUM> and a second box <NUM>. The second sliding block <NUM> is an elongated sliding block, one end of which is connected to one side of the second box <NUM> and the other end of which is slidably inserted into the sliding chute <NUM> through the second chute mouth <NUM>.

The same device as the flexible lock <NUM> is also arranged between the second sliding block <NUM> and the sliding chute <NUM>. The latch corresponding to the lock tongue set on the second sliding block <NUM> is disposed near the second chute mouth <NUM> of the sliding chute <NUM>.

A sliding direction of the first sliding block <NUM> is opposite to that of the second sliding block <NUM>. The first sliding block <NUM> and the second sliding block <NUM> are alternatively inserted into the sliding chutes <NUM>. It is beneficial for the first bracket <NUM> and the second bracket <NUM> to be evenly stressed, thereby improving a lifespan of the display device <NUM>.

In order to enable the first scroll <NUM> and the second scroll <NUM> to rotate autonomously, the display device <NUM> further includes a first motor and a second motor. The first motor has a first rotor. The first rotor is connected to the first scroll <NUM> to control a rotation of the first scroll <NUM>. Specifically, a rotation direction of the first rotor includes a first direction and a second direction.

The second motor has a second rotor. The second rotor is connected to the second scroll <NUM> to control a rotation of the second scroll <NUM>. Specifically, a rotation direction of the second rotor includes a third direction and a fourth direction. The first direction and the third direction are parallel to each other and opposite directions. The second direction and the fourth direction are parallel to each other and opposite directions.
