Description

Technical Field

[0001] The utility model belongs to the technical field of folding screens, and specifically relates to a folding screen device. Background Art

[0002] At present, foldable devices use flexible screens, and optical sensors are installed under the flexible screen for dimming, recognition and other functions. The existing technology usually installs the optical sensor in a light-proof cover, and then installs the light-proof cover on the flexible screen with interference fit, which has the effect of encapsulating the optical sensor to avoid interference from screen light or internal optical devices. In actual operation, the flexible screen is soft, and the optical sensor is easily squeezed by the interference fit between the light-proof cover and the flexible screen, causing bulges on the flexible screen and an uneven surface. In addition, due to the uneven surface of the flexible screen, a suspended gap appears between the optical sensor and the flexible screen. The optical sensor is affected by ambient light during the sensing process, causing light to penetrate the optical sensing hole of the optical sensor, and the sensing function of the optical sensor fails. If the light-proof cover and the flexible screen are not well matched, they cannot effectively contact the flexible screen, so that the optical sensor cannot be effectively encapsulated, resulting in light leakage and failure of the sensing function. Utility Model Content

[0003] The purpose of the present utility model is to overcome the shortcomings and deficiencies in the prior art and to provide a folding screen device, in which an optical sensor is installed on a flexible screen through foam, thereby avoiding unevenness caused by excessive squeezing of the flexible screen.

[0004] The utility model is realized by the following technical solutions:

[0005] A folding screen device comprises a mounting shell, a flexible screen, and an optical sensor, a light-proof sleeve and a foam component located in the mounting shell; the flexible screen is mounted on the mounting shell; the light-proof sleeve is arranged outside the optical sensor, and a first photosensitive hole corresponding to a photosensitive area of ​​the optical sensor is formed on a side of the light-proof sleeve facing the flexible screen; the foam component is arranged on a side of the light-proof sleeve facing the flexible screen, and a second photosensitive hole corresponding to the first photosensitive hole is formed through the foam component, and the first photosensitive hole is connected to the second photosensitive hole; a side of the foam component facing away from the light-proof sleeve abuts against the flexible screen.

[0006] In the folding screen device provided by the utility model, a light-proof sleeve is arranged outside the optical sensor to prevent external optical fiber from interfering with the optical sensor. The optical sensor is installed on the flexible screen through foam. Since the density and hardness of the foam are relatively low, excessive squeezing of the flexible screen to cause unevenness can be avoided during installation.

[0007] Further, the installation housing further includes a support layer and a fixing frame disposed around the support layer. The support layer and the flexible screen are respectively installed on two sides of the fixing frame, and the light-shielding cover is disposed on a side of the support layer facing the flexible screen. The support layer plays a role in stably supporting the light-shielding cover, so that the light-shielding cover can stably provide the light-shielding effect for the optical sensor.

[0008] Further, the foam member is attached to a side of the light-shielding cover facing the flexible screen. The foam member is located between the flexible screen and the light-shielding cover, and its two sides are respectively attached to the flexible screen and the light-shielding cover to form a light-shielding environment and prevent the optical sensor from being affected by ambient light.

[0009] Further, the foam member is fixed to a side of the light-shielding cover facing the flexible screen through an adhesive layer.

[0010] Further, an opening is provided on a side of the light-shielding cover facing the support layer. A part of the optical sensor is located outside the opening of the light-shielding cover and abuts against the support layer. The support layer provides support for the light-shielding cover and the optical sensor to prevent displacement.

[0011] Further, the foam member is in interference fit with the flexible screen. The interference fit avoids leaving a gap between the foam member and the flexible screen, which may cause light from the flexible screen to interfere with the sensing of the optical sensor.

[0012] Further, the optical sensor includes a sensor housing and a photosensitive part fixed on the sensor housing. A part of the sensor housing is located outside the opening of the light-shielding cover, and the light-shielding cover is sleeved on the photosensitive part.

[0013] Further, the thickness of the foam member is greater than the distance between the light-shielding cover and the flexible screen. By applying pressure to the sensor housing through the support layer, the foam member is squeezed until it can adapt to the distance between the light-shielding cover and the flexible screen, realizing the interference fit between the foam member and the flexible screen.

[0014] Further, the foam member is in a sheet shape.

[0015] For better understanding and implementation, the present invention will be described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 It is a schematic installation diagram of the optical sensor. Figure 3 It is a schematic structural diagram of the light-shielding cover. Figure 4 It is a schematic structural diagram of the foam part. Please refer to Figures 1-4, The folding screen device includes a mounting housing, a flexible screen 1, an optical sensor 2, a light-shielding sleeve 3, and a foam member 4 located inside the mounting housing; the flexible screen 1 is mounted on the mounting housing; the light-shielding sleeve 3 is sleeved outside the optical sensor 2, and a first photosensitive hole 31 corresponding to the photosensitive area of the optical sensor 2 is formed on the side of the light-shielding sleeve 3 facing the flexible screen 1; the foam member 4 is disposed on the side of the light-shielding sleeve 3 facing the flexible screen 1, and a second photosensitive hole 41 corresponding to the first photosensitive hole 31 is formed through the foam member 4, and the first photosensitive hole 31 communicates with the second photosensitive hole 41; the side of the foam member 4 facing away from the light-shielding sleeve 3 abuts against the flexible screen 1.

The optical sensor 2 is mounted on the flexible screen 1 through the foam. Since the density and hardness of the foam are relatively low, excessive squeezing of the flexible screen 1 resulting in unevenness can be avoided during installation.

[0029] Figure 5 is a cross-sectional view of the folding screen device, please refer to Figure 5 , Compared with the prior art, the design of directly connecting a silica gel sleeve with a relatively large hardness to the flexible screen 1 is cancelled in this embodiment.

While achieving close fitting between the foam member 4 and the flexible screen 1 to prevent light leakage, excessive squeezing of the flexible screen 1 causing unevenness of the flexible screen 1 is avoided.

[0032] In this embodiment, the foam member 4 is fixed to the side of the light-shielding cover 3 facing the flexible screen 1 through an adhesive layer. In one implementation, the foam member 4 is in the shape of a thin sheet.

[0034] In this embodiment, the foam member 4 is in interference fit with the flexible screen 1. Through the interference fit, gaps are avoided between the foam member 4 and the flexible screen 1, preventing the light of the flexible screen 1 from interfering with the sensing of the optical sensor 2.

Please refer to Figures 6-7 , in this embodiment, the optical sensor 2 includes a sensor housing 21 and a photosensitive part 22 fixed on the sensor housing 21. Part of the sensor housing 21 is located outside the opening of the light-shielding cover 3, and the light-shielding cover 3 is sleeved on the photosensitive part 22.

[0036] In this embodiment, the thickness of the foam member 4 is greater than the distance between the light-shielding cover 3 and the flexible screen 1.
