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 1 The 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 internal front cross-sectional structure of the main body provided in an embodiment of the present invention is shown. Figure 4 This diagram shows a partially enlarged structure of the lead screw provided in an embodiment of the present invention. 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 6As 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 bridge; 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), a driving mechanism is provided in the main body 1. The first nose pad 2 and the second nose pad 3 are both connected to the driving mechanism. The driving mechanism can drive the first nose pad 2 and the second nose pad 3 to adjust their positions, so as to adjust the spacing between the first nose pad 2 and the second nose pad 3.

[0037] In one specific embodiment of the present invention, such as Figures 2 to 4 As shown, to achieve the position adjustment of the first nose pad 2 and the second nose pad 3 by the drive mechanism, the drive mechanism may include a lead screw 61, a first slider 62, and a second slider 63. The lead screw 61 is rotatably connected inside the main body 1 and has an external thread. The first slider 62 and the second slider 63 each have an internal thread hole. The inner walls of the internal thread holes on the first slider 62 and the second slider 63 are provided with internal threads that are compatible with the external threads. The first slider 62 and the second slider 63 are respectively sleeved on the lead screw 61 through their respective internal thread holes and are screwed to the lead screw 61 through their respective internal threads engaging with the external threads on the lead screw 61. In addition, to achieve the connection between the drive mechanism and the two nose pads, the side of the first slider 62 away from the lead screw 61 needs to be fixedly connected to the first nose pad 2, and the side of the second slider 63 away from the lead screw 61 needs to be fixedly connected to the second nose pad 3, thereby realizing the drive mechanism to drive the first nose pad 2 and the second nose pad 3.

[0038] It should be noted that a limiting boss 67 needs to be provided in the middle of the lead screw 61, and the external threads on the parts of the lead screw 61 located on both sides of the limiting boss 67 need to be in opposite directions. This arrangement allows the two sliders to move towards or away from each other during the rotation of the lead screw 61. For example, when the lead screw rotates in the forward direction, the first slider 62 and the second slider 63 move towards each other, and the first nose support 2 and the second nose support 3 also move closer to each other accordingly. When the lead screw 61 rotates in the reverse direction, the first slider 62 and the second slider 63 move in the opposite direction, and the first nose support 2 and the second nose support 3 move away from each other accordingly, thereby adjusting the distance between the two nose supports. Of course, providing a limiting boss 67 in the middle of the lead screw 61 can also limit the movement of the first slider 62 and the second slider 63, preventing the two sliders from moving too far (especially when they are close to each other).

[0039] Furthermore, it should be further explained that in the actual design process, the direction of the external thread on the lead screw 61 can be set as needed. For example, by changing the direction of the external thread on the lead screw 61, when the lead screw 61 rotates in the forward direction, the first slider 62 and the second slider 63 move in opposite directions; when the lead screw 61 rotates in the reverse direction, the first slider 62 and the second slider 63 move towards each other.

[0040] Both the first nose pad 2 and the second nose pad 3 are located outside the main body 1, while both the first slider 62 and the second slider 63 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 62 and the second slider 63), 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 62 away from the lead screw 61 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 63 away from the lead screw 61 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.

[0041] For the lead screw 61, in order to achieve its rotatable connection within the main body 1, a mounting groove 68 for mounting various components can be opened in the main body 1. A first support plate 66 and a second support plate 65 are provided in the mounting groove 68. One end of the lead screw 61 is rotatably connected to the first support plate 66, and the other end of the lead screw 61 is rotatably connected to the second support plate 65.

[0042] To provide driving force for the rotation of the lead screw 61, the drive mechanism may further include a drive motor 64 disposed within the main body 1. The output shaft of the drive motor 64 is fixedly connected to one end of the lead screw 61, thereby enabling the drive motor 64 to drive the lead screw 61 to rotate forward or in reverse. It should be noted that, for the drive motor 64, to facilitate precise control of its rotation, a stepper motor can be selected. By selecting a stepper motor, the angular displacement of the lead screw 61 can be precisely controlled, thereby precisely controlling the movement distance of the two sliders.

[0043] In addition, to ensure that the two sliders can slide stably and prevent them from rotating with the lead screw 61, a guide rail parallel to the lead screw 61 can be provided in the main body 1. The first slider 62 and the second slider 63 are slidably connected to the guide rail, thereby guiding the first slider 62 and the second slider 63 and ensuring that the two sliders can slide stably.

[0044] Specifically, regarding the fabrication of the guide rail, it may include a guide rod 69 parallel to the lead screw 61. To achieve a sliding connection between the first slider 62 and the second slider 63 and the guide rod 69, a first guide hole may be provided on the first slider 62, and a second guide hole may be provided on the second slider 63. The guide rod 69 passes through the first guide hole and the second guide hole in sequence, thereby achieving a sliding connection between the first slider 62 and the second slider 63 and the guide rod 69. Furthermore, to further enhance the guiding effect of the guide rail on the sliders, the guide rail may also include a guide groove located below the lead screw 61. The guide groove is parallel to the lead screw 61, and the bottoms of the first slider 62 and the second slider 63 are both limited to the guide groove and can slide along it.

[0045] In another specific embodiment of the 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 drive mechanism, and the main body 1 is connected to the frame 5 through the connecting end 4.

[0046] In addition, a connecting block 41 can be fixed on the connecting end 4, and a rotary motor 51 (preferably a stepper motor) can be installed inside the outer frame 5. A drive shaft 52 is connected to the output shaft of the rotary motor 51, and a positioning hole 42 adapted to the drive shaft 52 is provided on the connecting block 41. The drive shaft 52 extends into the positioning hole 42 and is fixed to the connecting block 41 by screws 43. At this time, the connecting end 4 is synchronously fixed with the drive shaft 52, and the connecting end 4 is rotatably connected to the frame 5 through the rotary motor 51. In actual operation, the rotary motor 51 can control the entire nose pad module to rotate at a small angle on the frame 5, thereby realizing the adjustment of the angle between the nose pad module and the frame 5, increasing the adjustability of the nose pad module, and further improving the wearing comfort of the wearer.

[0047] 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:

[0048] 1. By setting a drive mechanism inside the main body of the nose pad module and connecting the first and second nose pads to the drive mechanism, the distance between the first and second nose pads can be adjusted in a timely manner through the drive mechanism, thereby improving the wearer's comfort.

[0049] 2. By setting up components such as drive motor, lead screw, slider, and guide rail, it is possible to move the first nose pad closer to the second nose pad or further away from the first nose pad, ensuring that the displacement of the first and second nose pads is always equal during the movement, thus achieving synchronous adjustment of the two nose pads.

[0050] 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.

[0051] 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.
