Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are some, not all embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the present invention, belong to the protection scope of the present invention.

The embodiment of the utility model provides a metal support spare for collapsible flexible screen, as shown in fig. 1, this metal support spare includes first non-bending area 12, second non-bending area 13 and at least one bending area 11, first non-bending area 12 is located respectively with second non-bending area 13 the both sides in bending area, at least one be equipped with a plurality of fretwork regions 111 in the bending area 11, be equipped with half-etching area 121 in first non-bending area 12 and/or the second non-bending area 13, half-etching area 121 does first non-bending area 12 and/or the second non-bending area 13 deviate from the terminal surface of flexible screen one side.

The half etching is to etch a part of the area in the first non-bending region 12 and/or the second non-bending region 13 by a chemical etching process, for example, the thickness of the metal support is 0.2mm, the thickness of the half etching region 121 may be 0.1mm, wherein the thickness of 0.1mm is removed by the chemical etching.

The specific method for forming the half-etched region 121 is to mask the corresponding position of the half-etched region 121 on one side of the first non-bending region 12 and/or the second non-bending region 13 during the exposure and development process of the negative film, i.e. only one side of the half-etched region can be etched by using an etching solution. That is, the etching solution etches only a single side of the support member during the etching process to form the half-etched region 121, and the depth of the half-etched hole is adjusted based on various parameters during the etching process, such as: concentration of etching solution, etching time, etc.

The metal support includes a first side and a second side, the half-etched area 121 is located on the first side, and the flexible screen is mounted on the second side of the metal support. The installation of the flexible screen requires a metal support to provide it with a high degree of flatness, so that the half-etched area 121 is located on the first side of the first non-bending area 12 and/or the second non-bending area 13, which can provide mechanical strength and flatness for the installation of the flexible screen, and at the same time reduce the mass of the whole metal support.

The half-etched area 121 is the first non-bending area 12 and/or the second non-bending area 13, and can be set according to the structure of the specific circuit board on which the metal supporting member is mounted. On the premise that the metal supporting member can ensure the support of the flexible screen, a plurality of half-etched areas 121 are arranged on the first non-bending area 12 and the second non-bending area 13.

As shown in fig. 1, two half-etched areas 121 are disposed in the first non-bending area 12, the circular non-half-etched area 121 between the two half-etched areas 121 is used for being mounted in a wireless charging area of the foldable mobile phone, the wireless charging area on the circuit board needs to provide strong mechanical strength and flatness for the wireless charging area, and other areas do not need to be provided, so that only the wireless charging area needs to be set as the non-half-etched area 121, and other areas of the first non-bending area 12 are the half-etched areas 121, on the premise of ensuring that the mechanical strength and flatness are provided for the flexible screen and the circuit board, the quality of the metal support is reduced, the overall quality of the electronic device with the foldable flexible screen is further reduced, and user experience is improved.

The metal support is a metal piece made of any one of stainless steel, aluminum alloy and titanium alloy.

In one embodiment, as shown in fig. 1, the ratio of the depth of the half-etched region 121 to the thickness of the metal support is in the range of: 1.

The ratio of the depth of the half-etched area 121 to the thickness of the metal support in the above range can ensure the mechanical strength of the metal support while reducing the mass thereof.

When the ratio of the depth of the half-etched region 121 to the thickness of the metal support is less than 1.

When the ratio of the depth of the half-etched area 121 to the thickness of the metal support is greater than 2, the greater thickness of the half-etched area 121 ensures the mechanical strength of the metal support while also increasing the thickness of the metal support.

In one embodiment, the metal support has a thickness in the range of 0.05m to 0.45mm. The metal support member within the thickness range can not only ensure the mechanical strength of the metal support member, but also avoid the limitation of the bending movement of the flexible screen.

When the thickness of the metal support is less than 0.05mm, the excessively thin metal support is easily deformed and is weak in mechanical strength to hardly support the flexible screen. When the thickness of the supporting piece is larger than 0.45mm, the excessively thick metal supporting piece has strong mechanical strength, but the stress generated when the metal supporting piece is bent is large, so that the bending activity of the metal supporting piece is limited, and the user experience is reduced.

In an embodiment, as shown in fig. 2, the shape of the hollow-out region 111 is a strip, and the length direction of the hollow-out region 111 is parallel to the bending direction of the bending region 11.

The plurality of hollow-out areas 111 are arranged in the bending area 11, so that stress generated when the flexible screen is bent can be reduced, and the bending flexibility of the flexible screen is improved. The length direction of the hollow area 111 is set to be parallel to the bending direction of the bending area 11, so that the bending flexibility of the flexible screen is further improved.

Further, the hollow-out area 111 is rectangular, or oval, or arc-shaped, or irregular.

As shown in fig. 2, the bending region 11 is further provided with a plurality of protection regions 112, the protection regions 112 are communicated with the hollow regions 111, and the outer diameter of the protection regions 112 is greater than the outer diameter of the hollow regions 111.

Further, the protection regions 112 are located at two ends and a middle position of the hollow region 111.

The end region of the hollow-out region 111 is narrow, which increases the manufacturing difficulty of the metal supporting member, and the protection region 112 reduces the manufacturing difficulty of the metal supporting member. In addition, the protection region 112 disperses the stress generated when the metal support member is bent, and further improves the flexibility of the flexible screen during bending.

In an embodiment, as shown in fig. 2, the plurality of hollow-out areas 111 are disposed in a staggered manner along the bending direction of the bending area 11.

The stress that produces when metal support spare buckles can be dispersed to a plurality of fretwork areas 111 of crisscross setting, improves the flexibility when flexible screen buckles.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
