Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and more specifically, to a nose pad module with adjustable nose pad spacing. 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] Smart glasses typically consist of a frame, on which lenses, temples, and a nose pad module are mounted. The lenses are used to improve the wearer's vision, the temples are used to support the sides of the frame by resting on the wearer's ears, and the nose pad module is used to support the middle of the frame by resting on the bridge of the wearer's nose.

[0004] Traditional smart glasses have fixed nose pad positions and the distance between the two nose pads is fixed. However, different wearers have different nose bridge widths and heights. Therefore, for smart glasses with non-adjustable nose pad spacing, wearers can only make simple adjustments to the entire smart glasses by manual operation, which is not very effective and affects the wearer's comfort.

[0005] Based on the aforementioned technical issues, there is an urgent need for smart glasses that can adjust the distance between the nose pads. Summary of the Invention

[0035] Figure 1The three-dimensional structure of the nose pad module with adjustable nose pad spacing provided in an embodiment of the present invention is shown. Figure 2 The internal transmission principle of the nose pad module with adjustable nose pad spacing provided by an embodiment of the present invention is illustrated. Figure 3 The structure of the slide rail provided in an embodiment of the present invention is shown. Figure 4 The internal front cross-sectional structure of the main body provided in an embodiment of the present invention is shown. Figure 5 The rear view of the nose pad module with adjustable nose pad provided by an embodiment of the present invention is shown. Figure 6 A side cross-sectional view of the nose pad module with adjustable nose pads provided in an embodiment of the present invention is shown.

[0036] Combination Figures 1 to 6 As shown in the figure, the nose pad module with adjustable nose pad spacing provided in the embodiments of the present invention includes a main body 1 for internally carrying electronic components and a first nose pad 2 and a second nose pad 3 for fitting and supporting the sides of the wearer's nose. In order to adjust the position of the first nose pad 2 and the second nose pad 3 (especially the spacing between the two nose pads), both the first nose pad 2 and the second nose pad 3 need to be slidably connected to the main body 1. Furthermore, a first electromagnet 61 is provided in the first nose pad 2, and a second electromagnet 62 that interacts with the first electromagnet 61 is provided in the second nose pad 3.

[0037] In actual use, by controlling the magnetic force and magnetism of the first electromagnet 61 and the second electromagnet 62, a certain value (set according to actual needs) of magnetic force that attracts or repels each other can be configured for the first nose pad 2 and the second nose pad 3. Based on this force and the sliding connection between the nose pads (including the first nose pad 2 and the second nose pad 3) and the main body 1, the first nose pad 2 and the second nose pad 3 move towards each other or away from each other, thereby achieving the mutual approach or mutual distance, and thus completing the adjustment of the distance between them.

[0038] Specifically, in order to achieve a sliding connection between the first nose pad 2, the second nose pad 3 and the main body 1, a slide rail 65 can be provided in the main body 1, and the first slider 63 and the second slider 64 can be slidably connected on the slide rail 65. The first slider 63 is fixedly connected to the first nose pad 2, and the second slider 64 is fixedly connected to the second nose pad 3.

[0039] For the fabrication of the slide rail 65, the slide rail 65 may include a first sliding shaft 651. A first limiting boss 652 is fixed in the middle of the first sliding shaft 651. In order to realize the sliding connection between the first slider 63 and the second slider 64 and the first sliding shaft 651, a first guide sliding hole (not shown in the figure) can be opened on the first slider 63, and a second guide sliding hole (not shown in the figure) can be opened on the second slider 64. The first slider 63 is slidably connected to the first sliding shaft 651 through the first guide sliding hole, and the second slider 64 is slidably connected to the first sliding shaft 651 through the second guide sliding hole. The first slider 63 and the second slider 64 are located on both sides of the first limiting boss 652, thereby realizing the sliding connection between the first slider 63 and the second slider 64 and the first sliding shaft 651.

[0040] It should be noted that since both the first slider 63 and the second slider 64 are slidably connected to the slide rail 65, when the two sliders move away from each other, a corresponding balancing damping element is required to prevent them from moving too far during the process. When the two sliders move away from each other to a preset distance, the balancing damping element balances the magnetic repulsion between the two sliders (essentially the magnetic repulsion between the first electromagnet 61 and the second electromagnet 62), so that the forces on the first slider 63 and the second slider 64 reach equilibrium, thus fixing their positions. Of course, when the two sliders move closer to each other, the same balancing damping element is also required to prevent them from moving too close during the process. When the two sliders move closer to each other to a preset distance, the balancing damping element balances the magnetic attraction between the two sliders (essentially the magnetic attraction between the first electromagnet 61 and the second electromagnet 62), so that the forces on the first slider 63 and the second slider 64 reach equilibrium, thus fixing their positions.

[0041] For the fabrication of the balancing damping component, the balancing damping component may include a first spring 661, a second spring 662, a third spring 663, and a fourth spring 664, all of which are sleeved on the first sliding shaft 651; wherein, the first spring 661 is disposed on the side of the first slider 63 away from the first limiting boss 652, the second spring 662 is disposed between the first slider 63 and the first limiting boss 652, the third spring 663 is disposed between the second slider 64 and the first limiting boss 652, and the fourth spring 664 is disposed on the side of the second slider 64 away from the first limiting boss 652. In actual use, when the two nose pads approach each other through magnetic attraction, the second spring 662 and the third spring 663 are compressed (at this time, the first spring 661 and the fourth spring 664 are not compressed). The second spring 662 and the third spring 663 provide damping to balance the magnetic attraction between the two nose pads, thus fixing the position of the two nose pads. When the two nose pads move away from each other through magnetic attraction, the first spring 661 and the fourth spring 664 are compressed (at this time, the second spring 662 and the third spring 663 are not compressed). The first spring 661 and the fourth spring 664 provide damping to balance the magnetic repulsion between the two nose pads, thus fixing the position of the two nose pads.

[0042] It should be noted that the limiting bosses (including the first limiting boss and the second limiting boss) not only provide support for the springs (including the second spring, the third spring, the sixth spring and the seventh spring), but also limit the two nose pads to the limit, preventing the two nose pads from getting too close to each other.

[0043] For the sliders, simply setting a first sliding shaft 651 is insufficient to ensure that the two sliders slide axially along the first sliding shaft 651 without rotating. Therefore, the slide rail 65 may also include a second sliding shaft 653 parallel to the first sliding shaft 651, with a second limiting boss 654 fixed in the middle of the second sliding shaft 653. The first slider 63 and the second slider 64 are also slidably connected to the second sliding shaft 653 and are located on both sides of the second limiting boss 654. By setting two sliding shafts, the problem of the two sliders rotating circumferentially can be completely avoided.

[0044] Of course, a balancing damping component also needs to be provided for the second sliding shaft 653. That is, the balancing damping component may also include a fifth spring 665, a sixth spring 666, a seventh spring 667, and an eighth spring 668, all of which are sleeved on the second sliding shaft 653. Among them, the fifth spring 665 is located on the side of the first slider 63 away from the second limiting boss 654, the sixth spring 666 is located between the first slider 63 and the second limiting boss 654, the seventh spring 667 is located between the second slider 64 and the second limiting boss 654, and the eighth spring 668 is located on the side of the second slider 64 away from the second limiting boss 654. In actual use, when the two nose pads approach each other through magnetic attraction, the second spring 662, the third spring 663, the sixth spring 666, and the seventh spring 667 are compressed (at this time, the first spring 661, the fourth spring 664, the fifth spring 665, and the eighth spring 668 are not compressed). The second spring 662, the third spring 663, the sixth spring 666, and the seventh spring 667 provide damping to balance the magnetic attraction between the two nose pads, thus fixing the position of the two nose pads. When the two nose pads move away from each other through magnetic attraction, the first spring 661, the fourth spring 664, the fifth spring 665, and the eighth spring 668 are compressed (at this time, the second spring 662, the third spring 663, the sixth spring, and the seventh spring 667 are not compressed). The first spring 661, the fourth spring 664, the fifth spring 665, and the eighth spring 668 provide damping to balance the magnetic repulsion between the two nose pads, thus fixing the position of the two nose pads.

[0045] Both the first nose pad 2 and the second nose pad 3 are located outside the main body 1, while both the first slider 63 and the second slider 64 are located inside the main body 1. To achieve the connection between the nose pads (including the first nose pad 2 and the second nose pad 3) and the sliders (including the first slider 63 and the second slider 64), a first elongated hole (not shown in the figure) and a second elongated hole (not shown in the figure) can be opened on the side of the main body 1 near the nose pads (including the first nose pad 2 and the second nose pad 3). The end of the first slider 63 away from the slide rail 65 can extend to the outside of the main body 1 through the first elongated hole and be fixedly connected to the first nose pad 2. The end of the second slider 64 away from the slide rail 65 can extend to the outside of the main body 1 through the second elongated hole and be fixedly connected to the second nose pad 3, thereby achieving the connection between the nose pads and the sliders.

[0046] For the first electromagnet 61 and the second electromagnet 62, in order to control the magnetism and magnetic field of the first electromagnet 61 and the second electromagnet 62, the first electromagnet 61 can be equipped with a first coil, and the second electromagnet 62 can be equipped with a second coil. Both the first coil and the second coil are electrically connected to the main board; and...

[0047] The motherboard controls the direction and magnitude of the magnetic field generated by the first electromagnet 61 and the second electromagnet 62 by controlling the direction and magnitude of the current in the first coil and the second coil, thereby controlling the force (including magnetic attraction and magnetic repulsion) between the first electromagnet 61 and the second electromagnet 62.

[0048] Specifically, in another specific embodiment of the present invention, such as Figure 1 , Figure 5 as well as Figure 6 As shown, in order to connect the main body 1 and the frame 5, a connecting end 4 is provided on the side of the main body 1 away from the driving mechanism, and the main body 1 is connected to the frame 5 through the connecting end 4.

[0049] Furthermore, to adjust the angle between the frame and the nose pad module, a rotating drive component can be installed on the frame. A connecting block 41 adapted to the rotating drive component is fixed to the connecting end, allowing the connecting end to be rotatably connected to the frame via the rotating drive component and the connecting block. Specifically, the rotating drive component includes a rotating motor 51, with a transmission shaft 52 fixedly connected to the output shaft of the rotating motor 51. A positioning hole 42 adapted to the transmission shaft 52 is formed on the connecting block 41. The transmission shaft 52 extends into the positioning hole 42 and is fixed to the connecting block 41 with screws 43. At this time, the connecting end 4 is synchronously fixed with the transmission shaft 52, and the connecting end 4 is rotatably connected to the frame 5 via the rotating motor 51. In actual operation, the rotating motor 51 can control the entire nose pad module to rotate slightly on the frame 5, thereby adjusting the angle between the nose pad module and the frame 5, increasing the adjustability of the nose pad module, and further improving the wearer's comfort.

[0050] As can be seen from the above specific embodiments, the nose pad module with adjustable nose pad spacing provided by the present invention has at least the following advantages:

[0051] 1. By sliding the first nose pad and the second nose pad to the main body, and setting the first electromagnet in the first nose pad and the second electromagnet in the second nose pad, an interaction force can be generated between the first nose pad and the second nose pad, so that the first nose pad and the second nose pad slide closer to each other or slide further away from each other, thereby realizing the automatic adjustment of the distance between the first nose pad and the second nose pad and improving the comfort of the wearer.

[0052] 2. By configuring corresponding coils for the first and second electromagnets and electrically connecting the two coils to the main board, the main board can precisely control the magnitude and direction of the current in the coils to control the interaction force between the two electromagnets, thereby precisely controlling the distance between the two nose pads.

[0053] 3. By setting a rotary motor between the connecting end and the frame, the angle between the nose pad module and the frame can be adjusted, increasing the adjustability of the nose pad module and further improving the wearer's comfort.

[0054] As referred above Figures 1 to 6 An adjustable nose pad spacing 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 adjustable nose pad spacing 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.
