Description

Technical Field

[0001] This utility model relates to a flexible screen folding terminal, and more particularly to the central support structure therein. The flexible screen folding terminal can be a mobile terminal such as a mobile phone or a laptop. Background Technology

[0002] For inward-folding flexible screen folding terminals, when folded, the middle folded part of the flexible screen will sink below the height of the support and bulge out in an arc shape.

[0003] The support is located within the central housing and is fixedly connected to it, serving as a hinge or supporting structure for other components such as the flexible screen. Previously, the support within the central housing was fixed to it with screws. The screw head diameter is relatively large, thus placing certain requirements on the width of the support (i.e., the thickness of the flexible screen folding terminal when folded). If the support is designed to be narrower, the screw head will protrude into the clearance groove in the middle of the support for the bending section of the flexible screen, interfering with the folding section of the flexible screen when it is folded. Therefore, the thinning of the flexible screen folding terminal is greatly limited by this connection method. Using other methods such as welding would significantly increase costs. Utility Model Content

[0004] The purpose of this invention is to provide a central support structure for a flexible folding terminal, ensuring that the fixing structure of the central support does not interfere with the space available for avoiding the arc-shaped bulge in the center of the flexible screen folding mechanism. This facilitates the thinning of the flexible folding terminal while also reducing cost. To this end, this invention adopts the following technical solution:

[0005] The central support structure of a flexible screen folding terminal includes a central shell and a support. The support is installed inside the central shell. The support is characterized in that a first connecting part is provided on the outer sides of both sides, and a corresponding second connecting part is provided on the central shell. The first connecting part and the second connecting part are snapped together for installation.

[0006] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these technical solutions:

[0007] The support has a relief groove in the middle for the flexible screen when it is folded.

[0008] The support is provided with claws at both ends, and the two sides of the middle outer shell are provided with locking holes or slots that cooperate with the claws.

[0009] The second connecting part is positioned above the first connecting part and is also positioned axially above the first connecting part.

[0010] The support is provided with a hole for connection with the shaft.

[0011] The shaft includes the shaft of the rotating connecting arm in the hinge of the flexible screen folding terminal, the rotating connecting arm being connected to the left or right housing of the flexible screen folding terminal.

[0012] The support is installed from top to bottom into the middle shell, so that the first connecting part and the second connecting part are engaged. A flexible pad is provided between the bottom of the support and the middle shell. The flexible pad is pressed by the support to increase the friction force on the support and tighten the engagement.

[0013] The flexible pad is a silicone pad.

[0014] By adopting the technical solution of this utility model, the middle shell and the support of this utility model are snapped together on the outer sides of both sides of the support, and can be further installed through the flexible pad at the bottom of the support, so the installation is reliable and convenient, avoiding interference and avoiding the space of the arc-shaped bulge in the middle of the flexible screen folding, which is conducive to reducing the width of the support and is conducive to the thin design of the folding screen terminal. At the same time, the cost of this solution is much lower than that of welding and other methods. Attached Figure Description

[0024] See attached document Figures 1-8 The flexible screen folding terminal provided by this utility model has a central support structure, including a central shell 100 and a support 1. The support 1 is installed inside the central shell 100. The support 1 has a relief groove 10 in the middle to accommodate the arc-shaped bulge 300 when the flexible screen is folded. The support 1 has a first connecting part on the outer sides on both sides. The central shell 100 has a corresponding second connecting part. The first connecting part and the second connecting part are snapped together for installation. By setting a snap-fit ​​structure on the outer side, reliable connection and convenient installation are ensured. At the same time, interference with the space of the arc-shaped bulge in the middle of the flexible screen (relief groove 10) is avoided. Therefore, it is more feasible to reduce the width of the support 1, which is beneficial for the thin design of the folding screen terminal.

[0025] The support 1 has claws 11 at both ends as first connecting parts, and the middle outer shell 100 has locking holes 101 or slots on both sides that mate with the claws as second connecting parts. The claws 11 and the locking holes 101 are engaged and connected. The locking holes 101 or slots not only position the claws 11 from above, but also, in the axial direction, match the width of the locking holes 101 or slots with the claws 11, thus also positioning the claws 11.

[0026] In this embodiment, the support 1 is taken as the support 1 of the shaft 21 of the rotating connecting arm 20 in the hinge of the flexible screen folding terminal. The support 1 is provided with a hole connected to the shaft 21. The rotating connecting arm 20 is connected to the left shell 201 or the right shell 202 of the flexible screen folding terminal.

[0027] The support 1 is installed from top to bottom into the central housing 100, engaging with the claws and locking holes 101 or slots. A flexible pad 2 is provided between the bottom of the support 1 and the central housing 100, pressed by the support 1 to increase friction on the support 1 (preventing the support 1 from wobbling due to gaps between parts), and also tightening the engagement. The flexible pad 2 can be a silicone pad. The flexible pad 2 is not only thin, taking up almost no height space, but also serves to enhance friction and the engagement effect.

[0028] like Figure 9 As shown, when the support 1 is fixed with a conventional screw A (connecting the support 1 to the middle housing 100), if the width of the support 1 is reduced in order to make it thinner, the inner side of the screw head will protrude B into the relief groove 10, causing the arc-shaped bulge 300 in the middle of the folded interference flexible screen.
