Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and more specifically, to a nose pad module. Background Technology

[0002] With economic and technological development, the application of smart wearable devices is becoming increasingly widespread. For example, smart glasses allow people to not only improve their vision but also perceive their environment through electronic devices, achieving a multi-functional effect.

[0003] In addition to correcting the wearer's vision, smart glasses typically have a variety of other detection functions. For example, they can detect the pressure between the nose pad module on the smart glasses and the skin on the wearer's nose. Another example is the detection of the wearer's heart rate changes by emitting optical signals to the skin on the bridge of the nose through optical sensors (such as photoplethysmography (PPG)) built into the nose pad module.

[0004] However, for existing nose pad modules with built-in optical sensors, after the wearer puts on smart glasses, the optical signals emitted by the optical sensors (such as photoplethysmography (PPG)) towards the skin on the bridge of the wearer's nose can easily leak out into the outside through the gap between the nose pad module and the wearer's nose skin. The leaked optical signals not only cause the overall optical detection signal to lose light energy, but also some of them shine into the wearer's eyes, causing irritation or even damage to the wearer's eyes.

[0005] Based on the aforementioned technical issues, there is an urgent need for a solution that can effectively prevent the leakage of optical signals emitted by the nose pad module. Summary of the Invention

[0006] In view of the above problems, the purpose of this invention is to provide a nose pad module to solve the problem that the optical signals emitted by the nose pad module in existing smart glasses are easily leaked.

[0007] The nose pad module provided by this invention is applied to smart glasses; it includes a main body and a nose pad disposed on the main body, wherein light-blocking suction cups are sleeved around the periphery of each nose pad; and,

[0008] When the wearer wears the smart glasses, the outer periphery of the light-blocking suction cup adheres to and attaches to the wearer's nose bridge skin.

[0009] Furthermore, a preferred embodiment is that the nose pad has light-emitting and light-receiving points located within the light-shielding suction cup; and,

[0010] When the outer periphery of the light-shielding suction cup adheres to the wearer's nose bridge skin, the light emitted by the light-emitting point is contained within the closed space formed by the light-shielding suction cup, the nose pad, and the wearer's nose bridge skin.

[0011] Furthermore, a preferred embodiment is that the light-shielding suction cup is made of memory silicone.

[0012] Furthermore, in a preferred embodiment, both the nose pad and the light-shielding suction cup are injection-molded parts; and,

[0013] The nose pad and the light-shielding suction cup are fixed together by injection molding.

[0014] Furthermore, a preferred embodiment is that the light-shielding suction cup is a flexible component; and,

[0015] The light-blocking suction cup can be detachably fitted around the nose pad.

[0016] In addition, a preferred embodiment is that a connecting part is fixed on the inner side of the nose pad, a connecting hole is provided on the connecting part, a through hole is provided on the inner side of the light-shielding suction cup, the connecting part extends to the outside of the light-shielding suction cup through the through hole and is connected to the end of the main body through the connecting hole.

[0017] Furthermore, a preferred embodiment is that a positioning protrusion corresponding to the shape of the perforation is formed on the inner side of the nose pad, and the positioning protrusion is adapted to and connected to the perforation.

[0018] Furthermore, a preferred embodiment is that the main body has a U-shaped structure; and,

[0019] The nose pads are provided at both ends of the main body, and the light-shielding suction cups are fitted onto both nose pads.

[0020] Furthermore, a preferred embodiment is that the light-shielding suction cup has a contoured structure corresponding to the shape of the nose pad.

[0021] Furthermore, a preferred embodiment is that a connecting end is connected to the main body, and the main body is connected to the frame of the smart glasses through the connecting end.

[0022] Compared with the prior art, the nose pad module according to the present invention has the following advantages:

[0023] The nose pad module provided by the present invention, by setting a light-shielding suction cup around the nose pad of the nose pad module, enables all positions of the outer periphery of the light-shielding suction cup to adhere to the wearer's nose bridge skin, thereby forming a completely sealed space among the nose pad, the light-shielding suction cup and the wearer's nose bridge skin. The optical signal used for detection is contained in this sealed space and will not be exposed and affect the wearer's eyes.

However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Figure 1 The three-dimensional structure of the nose pad module provided in the embodiment of the present invention without the light-shielding suction cup is shown. Figure 2 The three-dimensional structure of the nose pad module provided in the embodiment of the present invention when the light-shielding suction cup is set is shown. Figure 3 The cross-sectional structure of the integrated light-shielding suction cup used in the nose pad module provided in an embodiment of the present invention is shown. Figure 4 The three-dimensional structure of the split light-shielding suction cup used in the nose pad module provided in an embodiment of the present invention is shown. Figure 5 The three-dimensional structure of the nose pad module provided in an embodiment of the present invention when worn is shown.

[0036] Combination Figures 1 to 5 As shown, the nose pad module provided by this invention is applied to smart glasses; it includes a main body 1 for internally carrying electronic components and a connecting end 2 fixed (can be integrally molded) and connected to one side of the main body 1. The main body 1 is connected to the frame of the smart glasses through the connecting end 2; a nose pad 3 is provided on the main body 1 to contact and support the wearer's nose bridge skin, and a light-blocking suction cup 4 is sleeved around the periphery of the nose pad 3. When the wearer wears the smart glasses, the outer periphery of the light-blocking suction cup 4 adheres and adheres to the wearer's nose bridge skin.

[0037] It should be noted that for the nose pad module with internal optical sensor, two light-transmitting windows are usually required on the nose pad 3, one for emitting light setting point 31 (e.g., for emitting a green signal light source) and the other for receiving light setting point 32. For the nose pad module provided by the present invention, the emitting light setting point 31 and the receiving light setting point 32 need to be within the enclosure of the light-shielding suction cup 4. In actual use, when the wearer wears the smart glasses, the outer circumference of the light-shielding suction cup 4 is attached to the wearer's nose bridge skin. With this setting, the light emitted by the emitting light setting point 31 is contained in the closed space formed by the light-shielding suction cup 4, the nose pad 3 and the wearer's nose bridge skin, and some of the reflected light is received by the receiving light setting point 32. The light in the closed space will not be exposed and will not affect the wearer's eyes.

[0038] In the actual manufacturing process, the light-blocking suction cup 4 is preferably made of memory silicone. Memory silicone has the property of shape memory. For the wearer, when wearing it for the first time, the memory silicone will remember the shape of the contact surface with the wearer's nose bridge and maintain this shape. When the wearer wears the smart glasses in subsequent times, it can ensure the wearer's comfort and prevent the exposure of optical signals.

[0039] In a specific embodiment of the present invention, the light-shielding suction cup 4 can be configured as an integral light-shielding suction cup 4. Both the nose pad 3 and the light-shielding suction cup 4 can be configured as injection molded parts. In the actual manufacturing process, the nose pad 3 is first injection molded, and then the nose pad 3 is encapsulated by secondary injection molding to form the light-shielding suction cup 4, so that the two (light-shielding suction cup 4 and nose pad 3) become one piece, and the two are fixed in one piece.

[0040] In another specific embodiment of the present invention, the light-shielding suction cup 4 can be configured as a split light-shielding suction cup 4. For this configuration, the light-shielding suction cup 4 needs to be configured as a flexible part; the nose pad 3 and the light-shielding suction cup 4 need to be molded separately, and then the light-shielding suction cup 4 is detachably sleeved on the periphery of the nose pad 3.

[0041] To enable the detachable function of the light-shielding suction cup 4, a connecting part 34 can be fixed to the inside of the nose pad 3. A connecting hole 35 is provided on the connecting part 34, and a through hole 41 is provided on the inside of the light-shielding suction cup 4. The connecting part 34 extends to the outside of the light-shielding suction cup 4 through the through hole 41 and is connected to the end of the main body 1 through the connecting hole 35. In actual use, when it is necessary to remove the light-shielding suction cup 4, the nose pad 3 can be removed from the main body 1 first through the connecting hole 35, and then the light-shielding suction cup 4 can be removed from the nose pad 3.

[0042] In addition, to improve the connection between the light-shielding suction cup 4 and the nose pad 3, a positioning protrusion 33 corresponding to the shape of the perforation 41 can be formed on the inner side of the nose pad 3. When the light-shielding suction cup 4 is fitted on the nose pad 3, the positioning protrusion 33 is adapted to the perforation 41 (at this time, the perforation 41 is just fitted on the positioning protrusion 33).

[0043] It should be noted that the main body 1 of the nose pad module needs to be designed in a U-shape to fit the sides of the wearer's nose. Nose pads 3 are provided at both ends of the main body 1, and light-blocking suction cups 4 are fitted onto both nose pads 3. During actual wear, the two light-blocking suction cups 4 adhere to the sides of the wearer's nose. Furthermore, to improve wearer comfort, the nose pads 3 are generally designed with a contoured structure; in this case, the light-blocking suction cups 4 need to be designed with a contoured structure corresponding to the shape of the nose pads 3.

[0044] As can be seen from the above specific embodiments, the nose pad module provided by the present invention has at least the following advantages:

[0045] 1. By setting a light-shielding suction cup around the nose pad of the nose pad module, the outer periphery of the light-shielding suction cup can be attached to the wearer's nose bridge skin at all positions, so that the nose pad, the light-shielding suction cup and the wearer's nose bridge skin form a completely sealed space. The optical signal used for detection is contained in this sealed space and will not be exposed and affect the wearer's eyes.

[0046] 2. By designing the light-shielding suction cup as a split structure, it is easy to disassemble, replace, and clean the mechanical function of the light-shielding suction cup.

[0047] 3. By making the light-shielding suction cup an integrated structure, the connection stability between the light-shielding suction cup and the nose pad can be significantly improved.

[0048] As referred above Figures 1 to 5 The nose pad module according to the present invention has been described by way of example. However, those skilled in the art will understand that various modifications can be made to the nose pad module proposed in the present invention without departing from the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
