Description

Technical Field

[0001] The utility model relates to an ultra-thin narrow-edge display screen, in particular to a hinge mechanism of the ultra-thin narrow-edge display screen. Background Art

[0002] Ultra-thin narrow-edge display screens are limited by internal space, and the layout of their built-in screens, hinges and other mechanisms is very demanding. Once the layout is unreasonable, the thickness of the display screen will increase or the narrow-edge design cannot be achieved. The existing display hinge mechanism consists of two hinge parts, one of which is fixedly connected to the C shell or D shell of devices such as laptops, and the other hinge part is connected to the A shell. In actual applications, some hinge parts are set on the back of the LCD, which increases the thickness of the display A shell, or are directly arranged on the outside of the LCD, which will cause the display screen to lack a narrow-edge effect, and both cannot meet the design requirements. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an ultra-thin narrow-edge display screen hinge mechanism which does not increase the thickness of the display screen and reasonably utilizes the internal space of the A shell in view of the deficiencies of the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0005] A hinge mechanism for an ultra-thin narrow-edge display screen, the display screen includes an A shell, the hinge mechanism includes a first hinge part and a second hinge part, the first hinge part and the second hinge part are arranged front and back with a gap between them, the first hinge part and the second hinge part are connected by a rotating shaft and a sleeve that are rotatably matched, the first hinge part extends to the corner position of the A shell, and the first hinge part and the A shell are fixed by glue.

[0006] Preferably, the shaft sleeve and the second hinged portion are integrally formed, and a fixing rod is formed at one end of the rotating shaft outside the shaft sleeve, and the fixing rod is fixedly connected to the first hinged portion.

[0007] Preferably, a grid-shaped notch portion is formed on a side of the first hinge portion facing the A shell.

[0008] Preferably, a hinge cover plate is included, the hinge cover plate covers the outer side of the first hinged portion, and the hinge cover plate is snap-connected with the A shell.

[0009] Preferably, at least two first buckles are provided on the inner side of the A shell, and at least two second buckles are provided on the edge of the hinge cover plate, and the first buckles correspond to the second buckles one by one and engage with each other.

[0010] In the hinge mechanism of the ultra-thin narrow-edge display screen disclosed by the present invention, the first hinge part is used for fixed connection with the A shell, and the second hinge part is used for fixed connection with the C shell or the D shell, so as to realize the flipping function of the display screen. Specifically, the first hinge part and the second hinge part are hingedly matched by a rotating shaft and a shaft sleeve. Since the first hinge part extends to the corner position of the A shell, the first hinge part does not interfere with the position of the LCD unit. Compared with the prior art, the present invention adopts the method of arranging the first hinge part at the corner position of the A shell, which not only avoids the increase of the thickness of the A shell of the display screen, but also does not need to avoid each other with the LCD unit, so that the display screen meets the design requirements of ultra-thin narrow edges.

[0015] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0016] The utility model discloses an ultra-thin narrow-edge display screen hinge mechanism, combined with Figures 1 to 4 As shown, the display screen includes an A shell 1, and the hinge mechanism includes a first hinge part 2 and a second hinge part 3, the first hinge part 2 and the second hinge part 3 are arranged front and back with a gap 4 therebetween, the first hinge part 2 and the second hinge part 3 are connected by a rotating shaft 5 and a sleeve 6 that are rotatably matched, the first hinge part 2 extends to the corner position of the A shell 1, and the first hinge part 2 and the A shell 1 are fixed by glue.

[0017] In the above structure, the first hinge part 2 is used to be fixedly connected to the A shell 1, and the second hinge part 3 is used to be fixedly connected to the C shell or the D shell, so as to realize the flipping function of the display screen. Specifically, the first hinge part 2 and the second hinge part 3 are hinged by using a rotating shaft 5 and a sleeve 6. Since the first hinge part 2 extends to the corner position of the A shell 1, the first hinge part 2 does not interfere with the LCD unit 100. Compared with the prior art, the utility model adopts the method of arranging the first hinge part 2 at the corner position of the A shell, which not only avoids the increase of the thickness of the A shell of the display screen, but also does not need to avoid each other with the LCD unit, so that the display screen meets the design requirements of ultra-thin narrow edges.

[0018] Combination Figure 3 and Figure 4 As shown, regarding the specific structure of the hinge mechanism, in this embodiment, the shaft sleeve 6 and the second hinged portion 3 are integrally formed, and a fixing rod 50 is formed at one end of the rotating shaft 5 outside the shaft sleeve 6, and the fixing rod 50 is fixedly connected to the first hinged portion 2. Specifically, a fixing arm 21 may be provided at the edge of the first hinged portion 2, and the fixing arm 21 is fixedly connected to the fixing rod 50.

[0019] As a preferred embodiment, a grid-shaped notch portion 20 is formed on a side of the first hinge portion 2 facing the A shell 1. The grid-shaped notch portion 20 is used to fully contact with the glue to enhance the bonding force between the first hinge portion 2 and the A shell 1.

[0020] Combination Figure 2 and Figure 3 As shown, this embodiment includes a hinge cover plate 7, which covers the outer side of the first hinged portion 2, and the hinge cover plate 7 is engaged with the A shell 1. Specifically, at least two first buckles 10 are provided on the inner side of the A shell 1, and at least two second buckles 70 are provided on the edge of the hinge cover plate 7, and the first buckles 10 correspond to the second buckles 70 one by one and are engaged with each other.

[0021] In the above structure, based on the snap-fitting relationship between the first buckle 10 and the second buckle 70, the hinge cover 7 is detachable and does not need to be fixed with glue, so the assembly process is further simplified.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
