Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart glasses technology, and in particular to a foldable smart glasses. Background Technology
[0002] With the widespread adoption of smart wearable devices, smart glasses, which can directly display information within the user's field of vision and enable convenient interaction, are gradually being applied to scenarios such as daily commutes and outdoor work. Among these applications, the lenses, as the core display medium of smart glasses, directly impact the user experience due to their display performance under different lighting conditions. Currently, existing smart glasses mainly borrow the automatic dimming logic from mobile phones, adjusting lens brightness by placing ambient light sensors in the frame or temples and combining this with software algorithms to adapt to different lighting conditions. However, in actual use, especially in bright outdoor lighting scenarios, there are still significant shortcomings in the user experience.
[0003] In bright outdoor environments, when sunlight shines directly on the lenses of smart glasses, two types of interference occur: On the one hand, the ambient light sensor detects strong light signals and uses algorithms to adjust the lens display brightness to a high level to ensure the clarity of the information content itself; on the other hand, direct sunlight will form specular reflections on the lens surface, producing glaring spots or reflective layers. This reflected light does not originate from the display content inside the lens, but is the result of external light directly acting on the lens surface. Even if the lens display brightness is adjusted to the highest level, the reflected light will still cover the display content, causing text, icons, and other information to become blurry. Users need to frequently adjust their head angle to avoid the reflections, reducing the ease of use.
[0004] Based on the above situation, we propose a foldable smart glasses to solve the above problems. Utility Model Content
[0005] This invention provides a foldable smart glasses to solve the problems existing in the prior art.
[0006] The technical problem solved by this utility model is achieved by the following technical solution: A foldable smart glasses includes a frame and a display lens installed within the frame. The display lens is used to receive image information reflected from a screen. The glasses also include a light-blocking lens, a contact mechanism, and a dimming module. The light-blocking lens is connected to the frame via a rotating connector. The light-blocking lens can be folded around the rotating connector to adjust the area it blocks from the display lens. The contact mechanism is located at the relative position of the frame and the light-blocking lens. The dimming module is connected to both the contact mechanism and the display lens. When the light-blocking lens is folded to different preset positions, the contact mechanism is activated accordingly, triggering the dimming module to adjust the brightness of the display lens to adapt to the lighting conditions of the current usage scenario.
[0007] Preferably, the contact mechanism includes multiple sets of contact units disposed on the rotating connector and conductive elements disposed on the lens frame and adapted to the contact units. The multiple sets of contact units are distributed at intervals along the folding trajectory of the light-shielding lens. Each set of contact units is independently electrically connected to the dimming module. When the light-shielding lens is folded to different preset positions, the conductive elements make contact with the corresponding set of contact units and conduct electricity.
[0008] Preferably, the rotating connector is provided with an arc-shaped spring, and the contact unit is installed on the arc-shaped spring. The frame is provided with an arc-shaped groove corresponding to the arc-shaped spring. When the light-blocking lens is folded to a preset position, the arc-shaped spring is engaged in the corresponding arc-shaped groove to form a positioning and generate tactile feedback.
[0009] Preferably, the dimming module includes an adjustable resistor element and a backlight driving circuit. The adjustable resistor element is connected in series in the backlight driving circuit, and the adjustment terminal of the adjustable resistor element is electrically connected to the contact mechanism. When different groups of contact units are turned on, the resistance value of the adjustable resistor element changes accordingly to change the output current of the backlight driving circuit, thereby realizing the graded adjustment of the brightness of the display lens.
[0010] Preferably, the number of contact units is at least 3 sets, and the spacing between two adjacent sets of contact units is adapted to the angle increment when the light-shielding lens is folded. When the light-shielding lens is folded around the rotating connector, the conductive component can change with the folding angle and contact different sets of contact units in sequence.
[0011] Preferably, the outer surface of the light-shielding lens is provided with an anti-glare layer, and the inner surface is provided with an anti-reflection layer.
[0012] The beneficial effects of this utility model are: by using a contact mechanism that corresponds to the change in the folding angle of the light-shielding lens, the brightness of the display lens can be adjusted in stages under different light-shielding conditions, so that the brightness matches the light environment after light shielding in real time, reducing the problem of asynchronous display brightness caused by changes in light.

Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0017] Reference Figures 1-6 As shown, a foldable smart glasses diagram, representing the prior art structure provided by this utility model, includes a frame 1 and a display lens 2 installed within the frame 1. The display lens 2 is a waveguide lens, capable of stably receiving image information reflected from the screen 11 inside the smart glasses and clearly presenting it to the user. A screen 11 is located above the frame 1, and the image on the screen 11 shines downwards onto a reflective lens 12 located below. The reflective lens 12 then reflects the image back onto the display lens 2, allowing it to enter the user's field of vision. However, when used outdoors or in strong sunlight, the display effect on the display lens 2 is poor. Currently, to solve this problem, an automatic dimming logic similar to that of a mobile phone screen 11 is typically used, adjusting the brightness of the display lens 2 after detecting the light signal through an ambient light sensor. However, direct sunlight will form a specular reflection on the surface of the display lens 2, creating a reflective layer. Even when the brightness of the display lens 2 is adjusted to its maximum, the reflected light will still cover the displayed content, requiring the user to frequently adjust their head angle to avoid the reflection. Therefore, we have made the following improvements to address the above problems: A light-shielding lens 3 is connected to the frame 1 via a rotating connector 4. The light-shielding lens 3 can be folded around the rotating connector 4 to adjust the area of shading the display lens 2. A contact mechanism is provided at the relative position of the frame 1 and the light-shielding lens 3. A dimming module 5 is also included. The dimming module 5 is connected to the contact mechanism and the display lens 2 respectively. When the light-shielding lens 3 is folded to different preset positions, the contact mechanism is activated accordingly, triggering the dimming module 5 to adjust the brightness of the display lens 2 to adapt to the light conditions of the current usage scenario. Specifically, the contact mechanism includes multiple sets of contact units 6 mounted on the rotating connector 4 and conductive elements 61 mounted on the frame 1 and adapted to the contact units 6. The multiple sets of contact units 6 are spaced apart along the folding trajectory of the light-shielding lens 3. Each set of contact units 6 is independently electrically connected to the dimming module 5. When the light-shielding lens 3 is folded to different preset positions, the conductive element 61 contacts and conducts electricity with the corresponding set of contact units 6. One end of the rotating connector 4 is rotatably connected to the frame 1, and the other end is fixedly connected to the light-shielding lens 3. When the light-shielding lens is folded... At time 3, the rotating connecting piece 4 and the contact unit 6 rotate synchronously. The contact unit 6 can be made of gold-plated copper sheet with good conductivity and wear resistance. Different folding angles result in different contact units 6 being contacted. After each group of contact units 6 is turned on, it transmits an independent electrical signal to the dimming module 5. The dimming module 5 includes an adjustable resistor element 51 and a backlight driving circuit 52. The adjustable resistor element 51 is connected in series in the backlight driving circuit 52, and the adjustment end of the adjustable resistor element 51 is electrically connected to the contact mechanism. Component 51 can be a commonly available multi-position fixed resistor with multiple preset resistance value levels, each with a different resistance value. One end of the backlight driving circuit 52 can be connected to a built-in battery, such as a button battery, and the other end is connected to the backlight source connected to the display lens 2, responsible for supplying current to the backlight source. The greater the current, the brighter the display lens 2. The adjustable resistor 51 is connected in series between the battery and the display lens 2, and the adjustable resistor 51 is directly connected to each group of contact units 6 of the contact mechanism through wires. When different groups of contact units 6 are turned on, the resistance value of the adjustable resistor 51 changes accordingly to change the output current of the backlight driving circuit 52, thereby realizing the graded adjustment of the brightness of the display lens 2. The control circuit board integrates signal receiving terminals corresponding to the number of contact units 6. Each receiving terminal is electrically connected to a group of contact units 6. When a group of contact units 6 makes contact with the conductive component 61 and is turned on, the corresponding signal receiving terminal will receive an electrical signal. The control circuit board then sends a command to the backlight adjustment circuit to adjust the backlight current of the display lens 2 to adjust the brightness.
[0018] Reference Figure 4-5 As shown, furthermore, in order to make the contact more reliable, the rotating connector 4 is provided with an arc-shaped spring 7, and the contact unit 6 is installed on the arc-shaped spring 7. The frame 1 is provided with an arc-shaped groove 71 corresponding to the arc-shaped spring 7. When the light-blocking lens 3 is folded to the preset position, the arc-shaped spring 7 is inserted into the corresponding arc-shaped groove 71 to form a positioning and generate tactile feedback. At this time, the user can know that the light-blocking lens 3 has been folded to one of the folding angles. When the rotating connector 4 is rotated, the rotating connector 4 will cause the arc-shaped spring 7 to move out of the arc-shaped groove 71, which will squeeze the arc-shaped spring 7 to deform and move it out.
[0019] The number of contact units 6 is at least 3 sets, and the spacing between two adjacent sets of contact units 6 is adapted to the angle increment when the light-shielding lens 3 is folded. When the light-shielding lens 3 is folded around the rotating connector 4, the conductive element 61 can change with the folding angle and contact different sets of contact units 6 in sequence. Preferably, the number of contact units 6 is set to 3 sets, respectively set to the angle between the light-shielding lens 3 and the display lens 2 of 0°, 90° and 108°, corresponding to the full light-shielding, partial light-shielding and no light-shielding levels, which can cover various scenarios such as strong midday light, diffuse light on cloudy days and weak indoor light, without the need to replace parts; the arc-shaped spring 7 and groove structure of the rotating connector 4 provide clear tactile feedback for level switching, and the user can complete the operation without visual inspection.
[0020] Furthermore, the outer surface of the light-shielding lens 3 is provided with an anti-glare layer, and the inner surface is provided with an anti-reflection layer. The anti-glare layer can be made of some matte coating to diffuse the strong light coming directly in, avoiding the glare spots formed when the sunlight is directly shining, while ensuring that the display content in the area not completely blocked by the light-shielding lens 3 is clearly visible. The anti-reflection layer can be made of some high refractive index materials to counteract the light reflection between the light-shielding lens 3 and the display lens 2, thereby improving the clarity of the image seen by the user.
[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
