Description

Technical Field

[0001] This invention relates to the field of microelectronic device packaging technology, and more specifically, to an automatic control system and control method for nose pad adjustment. 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 a control system that can automatically adjust the distance between the nose pads. Summary of the Invention

[0006] In view of the above problems, the purpose of this invention is to provide an automatic control system and control method for nose pad adjustment, so as to solve the problem that the existing nose pad spacing cannot be automatically adjusted.

[0007] The automatic nose pad adjustment control system provided by this invention is applied to smart glasses, and includes a main control module and a drive mechanism, a first pressure sensor, and a second pressure sensor electrically connected to the main control module; wherein...

[0008] A nose pad module is connected to the frame of the smart glasses. A first nose pad and a second nose pad are movably connected to the nose pad module. A first pressure sensor is disposed on the first nose pad, and a second pressure sensor is disposed on the second nose pad.

[0009] Both the first pressure sensor and the second pressure sensor send the collected signals to the main control module, and the main control module adjusts the first nose pad and the second nose pad through the drive mechanism based on the received signals.

[0010] Furthermore, in a preferred embodiment, the driving mechanism is disposed within the nose pad module, and both the first and second nose pads are connected to the driving mechanism; wherein,

[0011] The driving mechanism includes a drive motor, a lead screw connected to the drive motor, a first slider, and a second slider. A dividing block is provided in the middle of the lead screw. The external threads on the lead screw located on both sides of the dividing block are in opposite directions. The first slider and the second slider are both screwed onto the lead screw and located on opposite sides of the dividing block.

[0012] The first slider is connected to the first nose pad, and the second slider is connected to the second nose pad.

[0013] In addition, a preferred embodiment is that a guide rail parallel to the lead screw is provided inside the nose pad module, and both the first slider and the second slider are slidably connected to the guide rail.

[0014] Furthermore, in a preferred embodiment, the driving mechanism includes a slide rail, a first electromagnet, and a second electromagnet, wherein the slide rail is disposed within the nose pad module, the first electromagnet is disposed within the first nose pad, the second electromagnet is disposed within the second nose pad, a third slider is fixedly connected to the first nose pad, and a fourth slider is fixedly connected to the second nose pad; both the third and fourth sliders are slidably connected to the slide rail.

[0015] The first electromagnet is equipped with a first coil, and the second electromagnet is equipped with a second coil. Both the first coil and the second coil are electrically connected to the main control module.

[0016] Furthermore, a preferred embodiment is to provide a balancing damping element on the slide rail for balancing the forces between the first electromagnet and the second electromagnet.

[0017] In addition, a preferred embodiment includes a BTB interface, wherein the drive mechanism, the first pressure sensor, the second pressure sensor, and the main control module are all electrically connected to the BTB interface.

[0018] On the other hand, the present invention also provides an automatic control method for nose pad adjustment, the automatic control method being implemented based on the aforementioned automatic control system for nose pad adjustment, the automatic control method comprising:

[0019] The first pressure signal of the first nose pad is acquired by the first pressure sensor, and the second pressure signal of the second nose pad is acquired by the second pressure sensor.

[0020] The first pressure signal is converted into a first voltage signal and sent to the main control module; the second pressure signal is converted into a second voltage signal and sent to the main control module.

[0021] The main control module sends a drive signal to the drive mechanism based on the first voltage signal and the second voltage signal;

[0022] The drive mechanism adjusts the first nose pad and the second nose pad based on the drive signal.

[0023] Furthermore, in a preferred embodiment, the main control module sends the drive signal to the drive mechanism based on the first voltage signal and the second voltage signal, including:

[0024] When both the first voltage signal and the second voltage signal are less than a preset first threshold, the main control module sends a contraction drive signal to the drive mechanism;

[0025] When both the first voltage signal and the second voltage signal are greater than a preset second threshold, the main control module sends an extended drive signal to the drive mechanism.

[0026] Furthermore, in a preferred embodiment, the driving mechanism adjusts the first nose pad and the second nose pad based on the driving signal, including:

[0027] When the main control module sends a contraction drive signal to the drive mechanism, the drive motor drives the lead screw to rotate in the forward direction.

[0028] The forward rotation of the lead screw causes the first slider and the second slider to move closer to each other;

[0029] The first slider moves the first nose pad, and the second slider moves the second nose pad, causing both the first and second nose pads to retract inward; and...

[0030] When the main control module sends an extended drive signal to the drive mechanism, the drive motor drives the lead screw to rotate in the opposite direction;

[0031] The screw rotates in the opposite direction, causing the first slider and the second slider to move away from each other;

[0032] The first slider drives the first nose pad to move, and the second slider drives the second nose pad to move, so that the first nose pad and the second nose pad expand outward.

[0033] Furthermore, in a preferred embodiment, the driving mechanism adjusts the first nose pad and the second nose pad based on the driving signal, including:

[0034] When the main control module sends a retraction drive signal to the drive mechanism, the first electromagnet generates a first magnetic field through the first coil, and the second electromagnet generates a second magnetic field through the second coil; at this time, the first electromagnet and the second electromagnet attract each other, so that the third slider and the fourth slider move closer to each other;

[0035] The third slider drives the second nose pad to move, and the fourth slider drives the second nose pad to move, so that the first nose pad and the second nose pad retract inward; and...

[0036] When the main control module sends an extended drive signal to the drive mechanism, the first electromagnet generates a third magnetic field through the first coil, and the second electromagnet generates a fourth magnetic field through the second coil; at this time, the first electromagnet and the second electromagnet repel each other, so that the third slider and the fourth slider move away from each other.

[0037] The third slider drives the first nose pad to move, and the fourth slider drives the second nose pad to move, so that the first nose pad and the second nose pad expand outward.

[0038] Compared with the prior art, the automatic nose pad adjustment control system according to the present invention has the following advantages:

[0039] The automatic nose pad adjustment control system provided by this invention, by setting up a drive mechanism, in conjunction with pressure sensors (including a first pressure sensor and a second pressure sensor) and a main control module, can automatically adjust the position of the nose pads on the nose pad module according to actual needs (especially the adjustment of the distance between the two nose pads), without the need for the wearer to operate, thereby improving the wearer's comfort and convenience.

Figure 3 The internal front cross-sectional structure of the main body provided in the first embodiment of the present invention is shown.

Figure 7 The internal front cross-sectional structure of the main body provided in the second embodiment of the present invention is shown. Figure 8 The diagram shows the electrical control principle of the automatic nose pad adjustment control system provided by the present invention.

[0055] Combination Figures 1 to 8As shown in the embodiments of the present invention, the automatic nose pad adjustment control system is applied to smart glasses, including a main control module as the smart control center, a drive mechanism electrically connected to the main control module, a first pressure sensor, and a second pressure sensor (all three are electrically connected to the main control module respectively); wherein, the setting position of the main control module is set according to the requirements, usually set inside the frame of the smart glasses to be controlled, but it can also be set inside the temple; a nose pad module is connected to the middle of the frame, the nose pad module is used to support the smart glasses by resting on the bridge of the wearer's nose, and a first nose pad and a second nose pad are movably connected to the nose pad module, the first pressure sensor is set on the first nose pad, and the second pressure sensor is set on the second nose pad (the first nose pad and the second nose pad are components that actually fit in contact with the sides of the bridge of the wearer's nose).

[0056] Furthermore, the nose pad module includes a main body 1 for internally carrying electronic components, and a first nose pad 2 and a second nose pad 3 are both movably connected to the main body 1 and are respectively used to fit and support the sides of the wearer's nose bridge.

[0057] To achieve automatic adjustment of the two nose pad positions, the first pressure sensor needs to be installed on the first nose pad, and the second pressure sensor needs to be installed on the second nose pad. Both the first and second nose pads are connected to the drive mechanism. In actual use, when the wearer puts on the smart glasses, both the first and second pressure sensors will collect the pressure signals received on the corresponding nose pads and send the collected signals to the main control module. At this time, the main control module will send a drive signal to the drive mechanism based on the received signals, and the drive mechanism will automatically adjust the positions of the first and second nose pads.

[0058] In the first specific embodiment of the present invention, such as Figures 2 to 4As shown, to enable the drive mechanism to drive the two nose pads, the drive mechanism needs to be installed inside the nose pad module. The drive mechanism includes a drive motor, a lead screw connected to the drive motor, a first slider, and a second slider. 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 internal threaded holes adapted to the external threads. The inner walls of the internal threaded holes on the first slider 62 and the second slider 63 each have internal threads adapted to the external threads. The first slider 62 and the second slider 63 are respectively fitted onto the lead screw 61 through their respective internal threaded holes and are screwed onto the lead screw 61 through their respective internal threads engaging with the external threads on the lead screw 61. Furthermore, to connect the drive mechanism to the two nose pads, the end of the first slider 62 away from the lead screw 61 is connected to the first nose pad 4, and the end of the second slider 63 away from the lead screw 61 is connected to the second nose pad 5, thereby enabling the drive mechanism to drive the first nose pad 4 and the second nose pad 5.

[0059] It should be noted that a dividing block 67 needs to be set 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 dividing block 67 need to be in opposite directions. This setting allows the two sliders (including the first slider 62 and the second slider 63) 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. At this time, the first nose pad 4 moves under the drive of the first transmission mechanism, and the second nose pad 5 moves under the drive of the second transmission mechanism, thereby realizing the inward contraction of the two nose pads on the nose pad module. When the lead screw 61 rotates in the reverse direction, the first slider 62 and the second slider 63 move in opposite directions. At this time, the first nose pad 4 moves under the drive of the first slider, and the second nose pad 5 moves under the drive of the second slider, thereby realizing the outward expansion of the two nose pads on the nose pad module. Of course, setting the second slider 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 during the process of getting closer to each other).

[0060] Furthermore, it should be noted 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.

[0061] 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.

[0062] To provide driving force for the rotation of the lead screw 61, 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 backward. It should be noted that, for the drive motor 64, to facilitate precise control of its rotation, a stepper motor can be selected. By using 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. Furthermore, to ensure stable sliding of the two sliders and prevent them from rotating with the lead screw, a guide rail parallel to the lead screw can be provided inside the main body. Both the first and second sliders are slidably connected to the guide rail, thereby guiding the first and second sliders and ensuring stable sliding of the two sliders.

[0063] In addition, to ensure that the two sliders can slide stably and to prevent the two sliders (including the first slider and the second slider) 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.

[0064] 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 (not shown in the figure) 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.

[0065] In a second specific embodiment of the present invention, such as Figures 5 to 7As shown, to enable the driving mechanism to drive the two nose pads, the driving mechanism needs to be set inside the nose pad module. The driving mechanism includes a slide rail, a first electromagnet, and a second electromagnet. The slide rail is set inside the nose pad module, the first electromagnet is set inside the first nose pad, and the second electromagnet is set inside the second nose pad. A third slider is fixedly connected to the first nose pad, and a fourth slider is fixedly connected to the second nose pad. Both the third and fourth sliders are slidably connected to the slide rail. Furthermore, the first electromagnet is equipped with a first coil, and the second electromagnet is equipped with a second coil. Both the first and second coils are electrically connected to the main control module.

[0066] For the fabrication of the slide rail 75, the slide rail 75 may include a first sliding shaft 751. A first limiting boss 752 is fixed in the middle of the first sliding shaft 751. In order to realize the sliding connection between the third slider 73 and the fourth slider 74 and the first sliding shaft 751, a first guide sliding hole (not shown in the figure) can be opened on the third slider 73, and a second guide sliding hole (not shown in the figure) can be opened on the fourth slider 74. The third slider 73 is slidably connected to the first sliding shaft 751 through the first guide sliding hole, and the fourth slider 74 is slidably connected to the first sliding shaft 751 through the second guide sliding hole. The third slider 73 and the fourth slider 74 are located on both sides of the first limiting boss 752, thereby realizing the sliding connection between the third slider 73 and the fourth slider 74 and the first sliding shaft 751.

[0067] It should be noted that since both the third slider 73 and the fourth slider 74 are slidably connected to the slide rail 75, 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 71 and the second electromagnet 72), so that the forces on the third slider 73 and the fourth slider 74 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 71 and the second electromagnet 72), so that the forces on the third slider 73 and the fourth slider 74 reach equilibrium, thus fixing their positions.

[0068] For the fabrication of the balancing damping component, the balancing damping component may include a first spring 761, a second spring 762, a third spring 763, and a fourth spring 764, all of which are sleeved on the first sliding shaft 751; wherein, the first spring 761 is disposed on the side of the third slider 73 away from the first limiting boss 752, the second spring 762 is disposed between the third slider 73 and the first limiting boss 752, the third spring 763 is disposed between the fourth slider 74 and the first limiting boss 752, and the fourth spring 764 is disposed on the side of the fourth slider 74 away from the first limiting boss 752. In actual use, when the two nose pads approach each other through magnetic attraction, the second spring 762 and the third spring 763 are compressed (at this time, the first spring 761 and the fourth spring 764 are not compressed). The second spring 762 and the third spring 763 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 761 and the fourth spring 764 are compressed (at this time, the second spring 762 and the third spring 763 are not compressed). The first spring 761 and the fourth spring 764 provide damping to balance the magnetic repulsion between the two nose pads, thus fixing the position of the two nose pads.

[0069] 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.

[0070] For the sliders, simply setting a first sliding shaft 751 is insufficient to ensure that the two sliders slide axially along the first sliding shaft 751 without rotating. Therefore, the slide rail 75 may also include a second sliding shaft 753 parallel to the first sliding shaft 751, with a second limiting boss 754 fixed in the middle of the second sliding shaft 753. The third slider 73 and the fourth slider 74 are also slidably connected to the second sliding shaft 753 and are located on both sides of the second limiting boss 754. By setting two sliding shafts, the problem of the two sliders rotating circumferentially can be completely avoided.

[0071] Of course, a balancing damping component also needs to be provided for the second sliding shaft 753. That is, the balancing damping component may also include a fifth spring 765, a sixth spring 767, a seventh spring 767, and an eighth spring 768, all of which are sleeved on the second sliding shaft 753. Among them, the fifth spring 765 is located on the side of the third slider 73 away from the second limiting boss 754, the sixth spring 767 is located between the third slider 73 and the second limiting boss 754, the seventh spring 767 is located between the fourth slider 74 and the second limiting boss 754, and the eighth spring 768 is located on the side of the fourth slider 74 away from the second limiting boss 754. In actual use, when the two nose pads approach each other through magnetic attraction, the second spring 762, the third spring 763, the sixth spring 767, and the seventh spring 767 are compressed (at this time, the first spring 761, the fourth spring 764, the fifth spring 765, and the eighth spring 768 are not compressed). The second spring 762, the third spring 763, the sixth spring 767, and the seventh spring 767 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 761, the fourth spring 764, the fifth spring 765, and the eighth spring 768 are compressed (at this time, the second spring 762, the third spring 763, the sixth spring, and the seventh spring 767 are not compressed). The first spring 761, the fourth spring 764, the fifth spring 765, and the eighth spring 768 provide damping to balance the magnetic repulsion between the two nose pads, thus fixing the position of the two nose pads.

[0072] Both the first nose pad 2 and the second nose pad 3 are located outside the main body 1, while the third slider 73 and the fourth slider 74 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 third slider 73 and the fourth slider 74), 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 third slider 73 away from the slide rail 75 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 fourth slider 74 away from the slide rail 75 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.

[0073] For the first electromagnet 71 and the second electromagnet 72, in order to control the magnetism and magnetic field of the first electromagnet 71 and the second electromagnet 72, the first electromagnet 71 can be equipped with a first coil, and the second electromagnet 72 can be equipped with a second coil. Both the first coil and the second coil are electrically connected to the main board; and...

[0074] The motherboard controls the direction and magnitude of the magnetic field generated by the first electromagnet 71 and the magnetic field generated by the second electromagnet 72 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 71 and the second electromagnet 72.

[0075] In another specific embodiment of the present invention, in order to connect the main body 1 with the frame, a connecting end 9 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 through the connecting end 9.

[0076] In another specific embodiment of the present invention, in order to provide power to the pressure sensor, the main control module, and the drive motor, the nose pad adjustment automatic control system provided in the embodiment of the present invention may include a power module. The location of the power module is set according to the requirements, usually inside the frame of the smart glasses to be controlled, but it may also be located inside the temple. Furthermore, the drive motor, the first pressure sensor, the second pressure sensor, and the main control module are all electrically connected to the power module, and the power module provides power to the pressure sensor, the main control module, and the drive motor.

[0077] To enable signal and electrical transmission between the main control module, power supply module, drive mechanism (mainly referring to the drive motor), and pressure sensor, the nose pad adjustment automatic control system provided in this embodiment of the invention may also include a BTB interface. The location of the BTB interface is set according to requirements, typically within the frame of the smart glasses to be controlled, but it can also be located inside the temple. Furthermore, the drive motor, the first pressure sensor, the second pressure sensor, the main control module, and the power supply module are all electrically connected to the BTB interface. The BTB interface is essentially a board-to-board connector used for electrical and signal transmission between multiple modules. It is a commonly used interface in the field; therefore, its specific structure and working principle will not be described in detail here.

[0078] On the other hand, to illustrate in detail the specific control process of the automatic nose pad adjustment control system provided by the present invention, the present invention also provides an automatic nose pad adjustment control method, which is implemented based on the aforementioned automatic nose pad adjustment control system, and includes:

[0079] First, the first pressure signal of the first nose pad is acquired by the first pressure sensor, and the second pressure signal of the second nose pad is acquired by the second pressure sensor.

[0080] Next, the first pressure signal is converted into a first voltage signal and sent to the main control module, and the second pressure signal is converted into a second voltage signal and sent to the main control module;

[0081] Then, the main control module sends a drive signal to the drive mechanism based on the first voltage signal and the second voltage signal;

[0082] Finally, the drive mechanism adjusts the first nose pad and the second nose pad based on the drive signal.

[0083] Specifically, the main control module sends the drive signal to the drive mechanism based on the first voltage signal and the second voltage signal, including:

[0084] When both the first voltage signal and the second voltage signal are less than a preset first threshold, the main control module sends a contraction drive signal to the drive mechanism;

[0085] When both the first voltage signal and the second voltage signal are greater than a preset second threshold, the main control module sends an extended drive signal to the drive mechanism.

[0086] For the automatic nose pad adjustment control system provided in the first embodiment of the present invention, the drive mechanism adjusts the first nose pad and the second nose pad based on the drive signal, including:

[0087] When the main control module sends a contraction drive signal to the drive mechanism, the drive motor drives the lead screw to rotate in the forward direction.

[0088] The forward rotation of the lead screw causes the first slider and the second slider to move closer to each other;

[0089] The first slider moves the first nose pad, and the second slider moves the second nose pad, causing both the first and second nose pads to retract inward; and...

[0090] When the main control module sends an extended drive signal to the drive mechanism, the drive motor drives the lead screw to rotate in the opposite direction;

[0091] The screw rotates in the opposite direction, causing the first slider and the second slider to move away from each other;

[0092] The first slider drives the first nose pad to move, and the second slider drives the second nose pad to move, so that the first nose pad and the second nose pad expand outward.

[0093] The automatic nose pad adjustment control system provided in the second embodiment of the present invention includes adjusting the first nose pad and the second nose pad based on the drive signal, comprising:

[0094] When the main control module sends a retraction drive signal to the drive mechanism, the first electromagnet generates a first magnetic field through the first coil, and the second electromagnet generates a second magnetic field through the second coil; at this time, the first electromagnet and the second electromagnet attract each other, so that the third slider and the fourth slider move closer to each other;

[0095] The third slider drives the second nose pad to move, and the fourth slider drives the second nose pad to move, so that the first nose pad and the second nose pad retract inward; and...

[0096] When the main control module sends an extended drive signal to the drive mechanism, the first electromagnet generates a third magnetic field through the first coil, and the second electromagnet generates a fourth magnetic field through the second coil; at this time, the first electromagnet and the second electromagnet repel each other, so that the third slider and the fourth slider move away from each other.

[0097] The third slider drives the first nose pad to move, and the fourth slider drives the second nose pad to move, so that the first nose pad and the second nose pad expand outward.

[0098] It should be noted that both the first threshold and the second threshold were obtained through a very high number of wearing tests. When the pressure signal is less than the first threshold, it indicates that the nose pad on that side does not fit the wearer's nose bridge well enough, and the smart glasses do not provide good support on that side. When the pressure signal is greater than the second threshold, it indicates that the nose pad on that side fits the wearer's nose bridge too tightly, and the wearer is uncomfortable wearing the glasses on that side.

[0099] It should be further explained that the shape of the two sides of the wearer's nose bridge is basically the same, and the first nose pad and the second nose pad are symmetrical structures. Therefore, the pressure signal received by the first pressure sensor is basically equal to the pressure signal received by the second sensor. Therefore, when the pressure signal on one side is less than the first threshold, the pressure signal on the other side is usually also less than the first threshold. When the pressure signal on one side is greater than the second threshold, the pressure signal on the other side is usually also greater than the second threshold.

[0100] As can be seen from the above specific embodiments, the adjustable nose pad module provided by the present invention has at least the following advantages:

[0101] 1. By setting a drive mechanism inside the main body, in conjunction with pressure sensors (including the first pressure sensor and the second pressure sensor) and the main control module, the position of the nose pads on the nose pad module can be automatically adjusted according to actual needs (especially the adjustment of the distance between the two nose pads), without the need for the wearer to operate, which can improve the wearer's comfort and convenience.

[0102] 2. By setting up components such as drive motor, lead screw, slider, and guide rail, it is possible to achieve inward contraction or outward expansion between the first and second nose pads, and to ensure 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.

[0103] 3. By setting components such as the first electromagnet and the second electromagnet, it is possible to achieve inward contraction or outward expansion between the first nose pad and the second nose pad, and to ensure that the displacement of the first nose pad and the second nose pad is always equal during the movement, so as to achieve synchronous adjustment of the two nose pads.

[0104] As referred above Figures 1 to 8 The automatic nose pad adjustment control system and control method according to the present invention have been described by way of example. However, those skilled in the art should understand that various modifications can be made to the automatic nose pad adjustment control system and control method 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.
