Description

Technical Field

[0001] This utility model relates to the field of smartwatch technology, specifically to a smartwatch glass cover and a smartwatch mounting structure. Background Technology

[0002] Currently, many smartwatches are equipped with blood oxygen sensors, which consist of a photodiode and an LED. Inside the watch case, the photodiode and LED are isolated to prevent the light emitted by the LED from being directly received by the photodiode, thus affecting the accuracy of the monitoring. Additionally, to prevent light leakage from the glass cover from affecting the accuracy of the monitoring, a layer of black ink is coated on the inside of the glass cover (the side facing inwards from the watch case). To ensure strength, the glass cover needs to maintain a certain thickness; however, the glass cover reflects some of the light emitted by the LED to the photodiode. Furthermore, the greater the thickness of the glass cover, the more light is reflected to the photodiode, thus reducing the detection accuracy. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a smart watch glass cover and a smart watch mounting structure, which can eliminate the influence of light reflection from the glass cover on the blood oxygen sensor detection.

[0004] To achieve the above objectives, this utility model discloses a smartwatch glass cover, which includes a glass body. A light-shielding layer is provided on one side of the glass body, and a light-masking film is provided on the other side of the glass body. Both the light-shielding layer and the light-masking film are provided with light-transmitting holes. The light-masking film includes alternating layers of silicon dioxide and titanium. At least two silicon dioxide layers are provided, and at least one titanium layer is provided. The sum of the number of silicon dioxide layers and the number of titanium layers is an odd number.

[0005] The thickness of the single-layer silicon dioxide layer is 10-1000 nm, and the thickness of the single-layer titanium layer is 10-1000 nm.

[0006] Along the direction away from the glass body, the thickness of the silicon dioxide layer decreases, and the thickness of the titanium layer also decreases. The decreasing thickness of the silicon and titanium layers in the first three layers primarily enhance the optical light absorption effect.

[0007] The thickness of the silicon dioxide layer is not less than the thickness of the titanium layer. The appearance and color effect of the product can be adjusted by superimposing the thicknesses of the silicon and titanium layers.

[0008] The silicon dioxide layer has five layers, and the titanium layer has four layers.

[0009] Along the direction away from the glass body, the thicknesses of the silicon dioxide layers are 300-600nm, 200-300nm, 50-200nm, 50-100nm and 10-50nm respectively, and the thicknesses of the titanium layers are 50-80nm, 30-50nm, 10-20nm and 2-10nm respectively.

[0010] The thickness of the matting film is 500-1000 nm.

[0011] The light-shielding layer is an ink layer.

[0012] This utility model also discloses a smartwatch mounting structure, which includes a blood oxygen sensor, a glass cover, and an opaque partition layer. The partition layer has mounting holes. The blood oxygen sensor includes a phototube and a light-emitting tube, which are respectively disposed in different mounting holes. The glass cover covers the opening of the mounting holes. The glass cover is the aforementioned smartwatch glass cover. The light-shielding layer is adjacent to the partition layer, and the mounting holes and light-transmitting holes are arranged in a one-to-one correspondence.

[0013] By adopting the above solution, a matte film is placed on the glass body. This film absorbs the light emitted by the pulse oximeter's light-emitting diode that does not escape through the light-transmitting hole, preventing this light from being directly reflected back to the pulse oximeter's phototube, thus ensuring the accuracy of the pulse oximeter's detection. Furthermore, the silica layer in the matte film ensures a tight bond between the film and the glass body, while the titanium layer in the film has low electrical resistance. By partially connecting it to the inside of the smartwatch, the matte film can also be used as a conductive medium on the outside of the smartwatch, such as as a charging port or electrodes for heart rate detection.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, this utility model discloses an installation structure for a smartwatch, which includes a blood oxygen sensor, a glass cover, and an opaque partition layer 20. The partition layer 20 is located inside the smartwatch and has two mounting holes 21. The blood oxygen sensor includes a phototube 11 and a light-emitting diode 12, which are respectively installed in different mounting holes 21. The glass cover covers the openings of the mounting holes 21.

[0023] In this case, the glass cover is a specially designed smartwatch glass cover to ensure the accuracy of the blood oxygen sensor. Specifically, it includes a glass body 31, with a light-shielding layer 32 on one side of the glass body 31 adjacent to the partition layer 20. The light-shielding layer 32 is preferably an ink layer. On the other side of the glass body 31, a matte film 33 is provided. Both the light-shielding layer 32 and the matte film 33 have light-transmitting holes 34 that correspond one-to-one with the mounting holes 21.

[0024] The matting film 33 is used to absorb light emitted by the light-emitting tube 12 that is not emitted through the light-transmitting hole 34. Specifically, the matting film 33 includes alternating layers of silicon dioxide 35 and titanium 36. At least two silicon dioxide layers 35 and at least one titanium layer 36 are provided, and the sum of the number of silicon dioxide layers 35 and the number of titanium layers 36 is odd, ensuring that the outermost layer of the matting film 33 is always a silicon dioxide layer. The thickness of a single silicon dioxide layer 35 is 10-1000 nm, and the thickness of a single titanium layer 36 is 10-1000 nm. Preferably, the thickness of the matting film 33 is 500-1000 nm to balance process simplicity, peel strength of the matting film 33, and light absorption.

[0025] As a further preferred embodiment, the thickness of the silicon dioxide layer 35 decreases along the direction away from the glass body 31, the thickness of the titanium layer 36 decreases, and the thickness of the silicon dioxide layer 35 is not less than the thickness of the titanium layer 36.

[0026] In a preferred embodiment, the silicon dioxide layer 35 is provided with five layers, and the titanium layer 36 is provided with four layers. Along the direction away from the glass body 31, the thicknesses of the silicon dioxide layers 35 are 300-600nm, 200-300nm, 50-200nm, 50-100nm and 10-50nm respectively, and the thicknesses of the titanium layers 36 are 50-80nm, 30-50nm, 10-20nm and 2-10nm respectively.

[0027] The key to this invention lies in the use of a matte film 33 on the glass body 31. This film absorbs light emitted by the pulse oximeter sensor's light-emitting tube 12 that does not exit through the light-transmitting hole 34, preventing this light from being directly reflected back to the photoelectric tube 11 of the pulse oximeter sensor, thus ensuring the accuracy of the pulse oximeter sensor's detection. Furthermore, the silicon dioxide layer 35 in the matte film 33 ensures a tight bond between the matte film 33 and the glass body 31. The titanium layer 36 in the matte film 33 has low electrical resistance; by partially connecting it to the interior of the smartwatch, the matte film 33 can also be used as a conductive medium on the exterior of the smartwatch, such as as a charging port or an electrode for heart rate detection.

[0028] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
