Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and more specifically, to an automatic control system and control method for 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] Smart glasses typically consist of a frame, with lenses, temples, and a nose pad module. The lenses improve the wearer's vision, the temples support the sides of the frame by resting on the wearer's ears, and the nose pad module has nose pads with nose cushions that contact the sides of the wearer's nose, thus supporting the center of the frame.

[0004] Traditional smart glasses have fixed nose pads and nose bridges in their nose pad module, and their positions are not adjustable (especially the distance between the two nose pads). However, different wearers have different widths and heights of their nose bridges. Therefore, for smart glasses with non-adjustable nose pads, 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 position of the nose pad or nose support. 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 pads, so as to solve the problem that the positions of nose pads and nose cushions in existing smart glasses cannot be automatically adjusted.

[0007] The automatic control system for the nose pad module provided by this invention 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. A nose pad module is connected to the frame of the smart glasses.

[0008] 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. Both the first and second nose pads are connected to the drive mechanism. Both the first and second pressure sensors send the collected signals to the main control module. The main control module adjusts the first and second nose pads via the drive mechanism based on the received signals; or...

A first nose pad is movably connected to the first nose pad, and a second nose pad is movably connected to the second nose pad. A first pressure sensor is disposed on the first nose pad, and a second pressure sensor is disposed on the second nose pad. Both the first and second nose pads are connected to the drive mechanism.

[0012] When the first nose pad and the second nose pad are fixedly connected to the nose pad module, a first transmission mechanism is provided in the first nose pad and a second transmission mechanism is provided in the second nose pad. The first slider is connected to the first nose pad through the first transmission mechanism, and the second slider is connected to the second nose pad through the second transmission mechanism.

[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, a preferred embodiment is that when the first nose pad and the second nose pad are fixedly connected to the nose pad module,

[0015] The first transmission mechanism includes a first connecting rod and a second connecting rod; wherein, one end of the first connecting rod is fixedly connected to the first slider, the other end of the first connecting rod is rotatably connected to one end of the second connecting rod, and the end of the second connecting rod away from the first connecting rod is rotatably connected to the first nose pad;

[0016] The second transmission mechanism includes a third link and a fourth link; wherein, one end of the third link is fixedly connected to the second slider, the other end of the third link is rotatably connected to one end of the fourth link, and the end of the fourth link away from the third link is rotatably connected to the second nose pad.

[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 a nose pad module, implemented based on the aforementioned automatic control system for a nose pad module, characterized in that...

[0019] When the first nose pad and the second nose pad are movably connected to the nose pad module, the automatic control method for the nose pad module includes:

[0020] 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.

[0021] 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.

[0022] The main control module sends a drive signal to the drive mechanism based on the first voltage signal and the second voltage signal;

[0023] The drive mechanism adjusts the first nose pad and the second nose pad based on the drive signal.

[0024] Furthermore, in a preferred embodiment, when the first nose pad and the second nose pad are fixedly connected to the nose pad module, the automatic control method for the nose pad module includes:

[0025] 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.

[0026] 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.

[0027] The main control module sends a drive signal to the drive mechanism based on the first voltage signal and the second voltage signal;

[0028] The drive mechanism adjusts the first nose pad and the second nose pad based on the drive signal through the first transmission mechanism and the second transmission mechanism.

[0029] 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:

[0030] 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;

[0031] 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.

[0032] Furthermore, in a preferred embodiment, the driving mechanism adjusts the first nose pad and the second nose pad based on the driving signal, including:

[0033] 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.

[0034] The forward rotation of the lead screw causes the first slider and the second slider to move closer to each other;

[0035] The first slider drives the first nose pad to move through the first transmission mechanism, and the second slider drives the second nose pad to move through the second transmission mechanism, so that the first nose pad and the second nose pad retract inward.

[0036] Furthermore, in a preferred embodiment, the driving mechanism adjusts the first nose pad and the second nose pad based on the driving signal, and further includes:

[0037] 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;

[0038] The screw rotates in the opposite direction, causing the first slider and the second slider to move away from each other;

[0039] The first slider drives the first nose pad to move through the first transmission mechanism, and the second slider drives the second nose pad to move through the second transmission mechanism, so that the first nose pad and the second nose pad expand outward.

[0041] The automatic control system and method for the nose pad module provided by this invention, when the first and second nose pads are movably connected to the nose pad module, can automatically adjust the position of the nose pads on the nose pad module (especially the adjustment of the distance between the two nose pads) according to actual needs by setting a drive mechanism in the nose pad module, cooperating with pressure sensors (including a first pressure sensor and a second pressure sensor) and a main control module, without requiring operation by the wearer, thus improving the wearer's comfort and convenience; when the first and second nose pads are fixedly connected to the nose pad module, can automatically adjust the position of the nose pads on the nose pad module (especially the adjustment of the distance between the two nose pads) according to actual needs by setting a drive mechanism in the nose pad module and a transmission mechanism (including a first transmission mechanism and a second transmission mechanism) in the nose pads (including a first pressure sensor and a second pressure sensor), cooperating with pressure sensors (including a first pressure sensor and a second pressure sensor) and a main control module, without requiring operation by the wearer, thus improving the wearer's comfort and convenience.

Figure 5 This diagram shows a partially enlarged structure of the lead screw provided in an embodiment of the present invention. Figure 6 The internal cross-sectional structure of the first nose bridge provided in an embodiment of the present invention is shown. Figure 7 The electrical control principle of the automatic control system for the nose pad module provided in an embodiment of the present invention is illustrated.

[0056] Combination Figures 1 to 7 As shown in the embodiments of the present invention, the automatic control system for the nose pad module includes a main control module as the intelligent control center, and a drive mechanism, a first pressure sensor, and a second pressure sensor (all three are electrically connected to the main control module) electrically connected to the main control module. The location of the main control module is set according to requirements, usually inside the frame of the smart glasses to be controlled, but it can also be located inside the temple. Furthermore, a nose pad module is connected to the middle of the frame, which is used to support the smart glasses by resting on the bridge of the wearer's nose.

[0057] 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 respectively connected to both sides of the main body 1; wherein a first nose pad 4 can be connected to the first nose pad 2. Figure 2 The first nose pad is not shown in the image. A second nose pad 5 can be connected to the second nose support 3. Figure 2 (The second nose pad is not shown in the image). The first nose pad 4 and the second nose pad 5 are used to fit and support the sides of the wearer's nose bridge, respectively.

[0058] In the first embodiment of the present invention, the first nose pad and the second nose pad are movably connected to both sides of the nose pad module. The first nose pad can be fixed on the first nose pad (or not), and the second nose pad can be fixed on the second nose pad (or not). When the first nose pad is fixed on the first nose pad, the first pressure sensor is located on the first nose pad on the first nose pad. When the first nose pad is not located, the first pressure sensor is located on the first nose pad. The second nose pad is similarly configured. To achieve automatic adjustment of the positions of the two nose pads, both the first nose pad and the second nose pad are connected to the driving mechanism. In actual use, when the wearer wears the smart glasses, both the first pressure sensor and the second pressure sensor 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 driving signal to the driving mechanism based on the received signals, and the driving mechanism will automatically adjust the positions of the first nose pad and the second nose pad.

[0059] 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. Both the first slider 62 and the second slider 63 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 also 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.

[0060] 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).

[0061] In the second embodiment of the present invention, the first nose pad and the second nose pad are respectively fixedly connected to both sides of the nose pad module. The first nose pad is movably connected to the first nose pad, and the second nose pad is movably connected to the second nose pad. In order to realize the automatic adjustment of the position of the two nose pads, the first pressure sensor needs to be set on the first nose pad 4, and the second pressure sensor needs to be set on the second nose pad 5. The first nose pad 4 and the second nose pad 5 are both connected to the driving mechanism. In actual use, when the wearer wears the smart glasses, the first pressure sensor and the second pressure sensor will collect the pressure signal received on the corresponding nose pad and send the collected signal to the main control module. At this time, the main control module will send a driving signal to the driving mechanism based on the received signal, and the driving mechanism will automatically adjust the position of the first nose pad and the second nose pad.

[0062] To enable the drive mechanism to drive the two nose pads, the drive mechanism needs to be located within 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 within the main body 1 and has an external thread. Both the first slider 62 and the second slider 63 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 also 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 through a first transmission mechanism, and the end of the second slider 63 away from the lead screw 61 is connected to the second nose pad 5 through a second transmission mechanism, thereby enabling the drive mechanism to drive the first nose pad 4 and the second nose pad 5.

[0063] 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 on both sides of the limiting boss 67 on the lead screw 61 should be in opposite directions. This arrangement allows the two sliders (including the first slider 62 and the second slider 63) to move towards or in opposite directions 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. The movement of the screw 61 causes the two nose pads to retract inward on the nose pad module. When the screw 61 rotates in the opposite 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 transmission mechanism, and the second nose pad 5 moves under the drive of the second transmission mechanism, thereby causing the two nose pads to expand outward on the nose pad module. Of course, the limiting boss 67 set in the middle of the 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).

[0064] 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.

[0065] For both the lead screw 61 in the first embodiment and the lead screw 61 in the second embodiment, in order to achieve their 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.

[0066] 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. 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 within 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.

[0067] 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.

[0068] 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.

[0069] In addition, in the second embodiment of the present invention, for the transmission mechanism (including a first transmission mechanism and a second transmission mechanism), in order to enable the two sliders to transmit the driving force received by the self-driving mechanism to the two nose pads, the first transmission mechanism may include a first connecting rod 71 and a second connecting rod 72; wherein, one end of the first connecting rod 71 is fixedly connected to the first slider 62, the other end of the first connecting rod 71 is rotatably connected to one end of the second connecting rod 72, and the end of the second connecting rod 72 away from the first connecting rod 71 is connected to the first nose pad 4; with this arrangement, when the first slider 62 moves laterally, the first connecting rod 71 moves laterally in the same direction. At this time, since the first connecting rod 71 and the second connecting rod 72 are rotatably connected, the second connecting rod 72 will perform a stretching action, thereby driving the first nose pad 4 to perform a telescopic action; and...

[0070] The second transmission mechanism includes a third link 81 and a fourth link 82. One end of the third link 81 is fixedly connected to the second slider 63, and the other end of the third link 81 is rotatably connected to one end of the fourth link 82. The end of the fourth link 82 away from the third link 81 is connected to the second nose pad 5. With this configuration, when the second slider 63 moves laterally, the third link 81 moves laterally in the same direction. Since the third link 81 and the fourth link 82 are rotatably connected, the fourth link 82 will stretch, thereby causing the second nose pad 5 to extend or retract. For the two nose pads, this results in either inward contraction or outward expansion.

[0071] It should be noted that, to ensure that the second link 72 and the fourth link 82 can extend and retract in the required direction, a first sliding guide groove can be provided in the first nose pad 2, and a second sliding guide groove can be provided in the second nose pad 3. The first transmission mechanism is located in the first sliding guide groove, and the second transmission mechanism is located in the second sliding guide groove. The first sliding guide groove may include a first inclined groove 21 and a first extension groove 22 that are connected. The first link 71 is located in the first inclined groove 21, and the second link 72 is located in the first extension groove 22. The second sliding guide groove may include a second inclined groove and a second extension groove that are connected. The third link 81 is located in the second inclined groove, and the fourth link 82 is located in the second extension groove. This design guides the movement of the second link 72 and the fourth link 82, allowing them to extend and retract as needed, thereby driving the two nose pads to retract inward or expand outward.

[0072] Furthermore, in actual operation, adjustments are made... Figure 2Taking the left nose pad (i.e., the first nose pad 4) as an example, the drive motor 64 drives the left slider (i.e., the first slider 62) to move to the left. The first connecting rod 71 then moves to the left within the first sliding guide groove. The first connecting rod 71 drives the upper end of the second connecting rod 72 to move to the left until the second connecting rod 72 touches the corner of the inner wall of the first sliding guide groove. Since the first connecting rod 71 and the second connecting rod 72 are rotatably connected by a pin, the second connecting rod 72 will rotate around its connecting shaft. Subsequently, due to the guiding and limiting effect of the first extension groove 22, the second connecting rod 72 moves downward within the first extension groove 22, thereby driving the left nose pad to move downward on the nose pad module. It should be noted that the working principle is the same for other actions of the nose pad, and will not be repeated here.

[0073] Both the first nose pad 4 and the second nose pad 5 are located outside the connecting part (including the first nose support 2 and the second nose support 3), while the second connecting rod 72 and the fourth connecting rod 82 are located inside the connecting part. To achieve the connection between the nose pads and the corresponding connecting rods, a first connecting block 41 can be connected to the first nose pad 4, and a first elongated hole 23 communicating with the first extension groove 22 can be opened on the first nose support 2. The first connecting block 41 extends into the first extension groove 22 through the first elongated hole 23 and is connected to the second connecting rod 72. A second connecting block 51 is connected to the second nose pad 5, and a second elongated hole communicating with the second extension groove can be opened on the second nose support 3. The second connecting block 51 extends into the second extension groove through the second elongated hole and is connected to the fourth connecting rod 82. Thus, the connection between the two nose pads and the corresponding connecting rods is achieved.

[0074] 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.

[0075] 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 automatic control system for the nose pad module provided in the embodiment of the present invention may further 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.

[0076] 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 automatic control system for the nose pad module provided in this embodiment of the invention may further 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, and it is a commonly used interface in the field. Therefore, the specific structure and working principle of the BTB interface will not be described in detail here.

[0077] On the other hand, to illustrate in detail the specific control process of the automatic control system for the nose pad module provided by the present invention, the present invention also provides an automatic control method for the nose pad module. This automatic control method is implemented based on the aforementioned automatic control system for the nose pad module. When the first nose pad and the second nose pad are movably connected to the nose pad module (corresponding to the first embodiment), the automatic control method includes:

[0078] 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.

[0079] 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;

[0080] Then, the main control module sends a drive signal to the drive mechanism based on the first voltage signal and the second voltage signal;

[0081] Finally, the drive mechanism adjusts the first nose pad and the second nose pad based on the drive signal.

[0082] On the other hand, when the first nose pad and the second nose pad are fixedly connected to the nose pad module (corresponding to the second embodiment), the automatic control method of the nose pad module includes:

[0083] 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.

[0084] Secondly, the first pressure signal from the first pressure sensor is converted into a first voltage signal and sent to the main control module, and the second pressure sensor is converted into a second voltage signal and sent to the main control module.

[0085] Then, the main control module sends a drive signal to the drive mechanism based on the first voltage signal and the second voltage signal;

[0086] Finally, the drive mechanism adjusts the first nose pad and the second nose pad based on the drive signal.

[0087] Specifically, for both the first and second embodiments, the process by which the main control module sends the drive signal to the drive mechanism based on the first voltage signal and the second voltage signal includes:

[0088] 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;

[0089] 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;

[0090] When both the first voltage signal and the second voltage signal are between the first threshold and the second threshold, the main control module does not send a drive signal to the drive mechanism.

[0091] 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.

[0092] 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.

[0093] Furthermore, in the second embodiment, the process by which the driving mechanism adjusts the first nose pad and the second nose pad based on the driving signal includes:

[0094] When the main control module sends a contraction drive signal to the drive mechanism, the drive motor drives the lead screw to rotate forward; the forward rotation of the lead screw causes the first slider and the second slider to move closer to each other; the first slider drives the first nose pad to move through the first transmission mechanism, and the second slider drives the second nose pad to move through the second transmission mechanism, so that the first nose pad and the second nose pad contract inward; and...

[0095] 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;

[0096] The screw rotates in the opposite direction, causing the first slider and the second slider to move away from each other;

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

[0098] As can be seen from the above specific embodiments, the automatic control system and control method for the nose pad module provided by the present invention have at least the following advantages:

[0099] 1. When the first and second nose pads are movably connected to the nose pad module, by setting a drive mechanism in the nose pad module, in conjunction with pressure sensors (including the first and second pressure sensors) 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.

[0100] 2. When the first and second nose pads are fixedly connected to the nose pad module, by setting a drive mechanism in the nose pad module and a transmission mechanism (including a first transmission mechanism and a second transmission mechanism) in the nose pads (including the first and second nose pads), in conjunction with pressure sensors (including a first pressure sensor and a second pressure sensor) and the main control module, the position of the nose pads on the nose pad module (especially the adjustment of the distance between the two nose pads) can be automatically adjusted according to actual needs without the wearer's operation, which can improve the wearer's comfort and convenience.

[0101] 3. By setting up components such as drive motor, lead screw, slider, and guide rail, it is possible to realize the inward contraction or outward expansion between the first nose pad and the second nose pad (or between the first nose support and the second nose support), and to ensure that the displacement of the first nose pad and the second nose pad (or between the first nose support and the second nose support) is always equal during the movement, so as to realize the synchronous adjustment of the two nose pads (or the two nose pads).

[0102] As per the above reference Figures 1 to 7An automatic control system and control method for a nose pad module 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 control system and control method for a 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.
