Description

Technical Field

[0001] This invention relates to the field of smart glasses, and in particular to a smart pair of glasses and its nose pad control method, as well as a computer-readable storage medium. Background Technology

[0002] Existing AR glasses primarily rely on plastic and elastic deformation to match the wearer's nose bridge, offering limited adjustment space and making it unsuitable for different wearers. This often results in a mismatch between the nose pads and the wearer's nose bridge. Because AR glasses are relatively heavy, a mismatch in the nose pads can cause significant pressure on the nose bridge, leading to discomfort and potentially leaving indentations, thus negatively impacting the wearer's experience. Summary of the Invention

[0003] The main objective of this invention is to propose a smart glasses system that allows the nose pads to be adjusted to fit the wearer's nose bridge, thereby improving the wearer's experience.

[0004] To achieve the above objectives, the present invention provides smart glasses comprising:

[0005] The main body of the glasses;

[0006] The nose pads are rotatably connected to the main body of the glasses.

[0007] The driving device is connected to the nose pad drive;

[0008] An elastic wave sensor is disposed on the nose pad; and

[0009] The controller is electrically connected to both the elastic wave sensor and the driving device. The controller is used to identify the actual contact position between the nose pad and the bridge of the nose based on the electrical signal detected by the elastic wave sensor, and to control the driving device to drive the nose pad to rotate based on the actual contact position and the target contact position, so as to adjust the contact position between the nose pad and the bridge of the nose to the target contact position.

[0010] Optionally, multiple elastic wave sensors are provided, and the multiple elastic wave sensors are spaced apart around the nose pad.

[0011] Optionally, a first pivot is provided between the nose pad and the main body of the glasses. The first pivot extends in a horizontal direction, and the driving device includes a first motor for driving the nose pad to rotate around the first pivot.

[0012] Optionally, a second pivot is provided between the nose pad and the main body of the glasses. The second pivot extends in a vertical direction. The driving device also includes a second motor, which drives the nose pad to rotate around the second pivot.

[0013] This invention also proposes a method for controlling the nose pads of smart glasses, comprising the following steps:

[0014] Electrical signals are acquired by an elastic wave sensor configured on the nose pad of the smart glasses;

[0015] The actual contact position between the nose pad and the bridge of the nose is identified based on the electrical signal.

[0016] Based on the actual contact position and the target contact position, the control drive device drives the nose pad to rotate, so as to adjust the contact position between the nose pad and the bridge of the nose to the target contact position.

[0017] Optionally, multiple elastic wave sensors are arranged at intervals around the nose pad, and the step of identifying the actual contact position between the nose pad and the bridge of the nose based on the electrical signal includes:

[0018] The actual contact position between the nose pad and the bridge of the nose is identified based on the time difference and / or intensity difference between the electrical signals of different elastic wave sensors.

[0019] Optionally, the step of controlling the driving device to rotate the nose pad according to the actual contact position and the target contact position includes:

[0020] Based on the actual contact position and the target contact position, the amount of rotation to be performed on the nose pad is obtained;

[0021] Based on the desired rotation amount, the drive device is controlled to drive the nose pad to rotate.

[0022] Optionally, a first pivot is provided between the nose pad and the main body of the glasses. The first pivot extends in a horizontal direction. The driving device includes a first motor, which drives the nose pad to rotate around the first pivot. The amount to be rotated includes the amount to be rotated around the first pivot.

[0023] The step of controlling the driving device to drive the nose pad to rotate according to the amount of rotation to be achieved includes:

[0024] Based on the amount to be flipped, the first motor is controlled to drive the nose pad to flip around the first rotating shaft by the amount to be flipped.

[0025] Optionally, a second rotating shaft is provided between the nose pad and the main body of the glasses. The second rotating shaft extends in a vertical direction. The driving device further includes a second motor, which is used to drive the nose pad to rotate around the second rotating shaft. The amount of rotation to be rotated also includes the amount of rotation to be rotated around the second rotating shaft.

[0026] The step of controlling the driving device to drive the nose pad to rotate according to the rotation amount further includes:

[0027] Based on the amount to be rotated, the second motor is controlled to drive the nose pad to rotate around the second axis by the amount to be rotated.

[0028] Optionally, after the step of identifying the actual contact position between the nose pad and the bridge of the nose based on the electrical signal, the nose pad control method further includes:

[0029] The contact position between the nose pad and the bridge of the nose after rotation is identified again by the electrical signal of the elastic wave sensor, and it is determined whether the contact position has been adjusted to the target contact position.

[0030] If so, the adjustment process ends;

[0031] If not, then the amount of rotation to be performed on the nose pad is obtained again based on the actual contact position and the target contact position, so as to control the driving device to drive the nose pad to rotate to the target contact position according to the amount of rotation to be performed.

[0032] The present invention also proposes a computer-readable storage medium storing a nose pad control program for smart glasses, wherein the nose pad control program for smart glasses, when executed by a controller, implements the steps of the aforementioned nose pad control method for smart glasses.

[0033] In this invention, the nose pad is rotatably connected to the main body of the glasses. Rotation of the nose pad relative to the main body of the glasses adjusts its contact position with the bridge of the nose to a target contact position. This means that when the nose pad contacts the bridge of the nose at this target contact position, the fit between the nose pad and the bridge is high, the contact area is large, and the pressure on the bridge of the nose is reduced. Specifically, when a user wears the smart glasses, after the nose pad contacts the bridge of the nose, the weight of the smart glasses creates pressure at the contact point, generating an elastic wave. An elastic wave sensor receives this elastic wave, thus detecting the actual contact position between the nose pad and the bridge of the nose. The controller compares the actual contact position with the target contact position to determine the direction of change or the required rotation amount for the nose pad to contact the bridge of the nose from the actual contact position to the target contact position. The driving device then drives the nose pad to rotate accordingly, allowing it to contact the bridge of the nose at the target contact position. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0046] This invention proposes a smart glasses, which includes Bluetooth glasses, VR glasses, AR glasses, and other glasses equipped with a control system.

[0047] In one embodiment of the present invention, such as Figures 1 to 3 As shown, the smart glasses include:

[0048] The main body of the glasses is 100.

[0049] The nose pad 200 is rotatably connected to the main body of the glasses 100;

[0050] The driving device is connected to the nose pad 200 in a driving manner;

[0051] An elastic wave sensor 300 is disposed on the nose pad 200; and

[0052] The controller is electrically connected to both the elastic wave sensor 300 and the driving device. The controller is used to identify the actual contact position between the nose pad 200 and the bridge of the nose 10 based on the electrical signal detected by the elastic wave sensor 300, and to control the driving device to drive the nose pad 200 to rotate based on the actual contact position and the target contact position 210, so as to adjust the contact position between the nose pad 200 and the bridge of the nose 10 to the target contact position 210.

[0053] In the technical solution of the present invention, the nose pad 200 is rotatably connected to the main body of the glasses 100. When the nose pad 200 rotates relative to the main body of the glasses 100, the position of the nose pad 200 in contact with the bridge of the nose 10 is adjusted to the target contact position 210. It can be understood that when the nose pad 200 contacts the bridge of the nose 10 through the target contact position 210, the fit between the nose pad 200 and the bridge of the nose 10 is high and the contact area is large, which can reduce the pressure on the bridge of the nose 10. Specifically, when a user wears smart glasses, after the nose pad 200 contacts the bridge of the nose 10, the weight of the smart glasses exerts pressure on the contact point, generating an elastic wave. The elastic wave sensor 300 can receive the elastic wave, thereby detecting the actual contact position between the nose pad 200 and the bridge of the nose 10. The controller compares the actual contact position with the target contact position 210 to determine the conversion direction or the required amount of rotation from the actual contact position to the target contact position 210. The drive device drives the nose pad 200 to rotate accordingly, so that the nose pad 200 contacts the bridge of the nose 10 through the target contact position 210.

[0054] Furthermore, the elastic wave sensor 300 has significant advantages over ordinary pressure sensors. First, the elastic wave generated by the contact between the nose pad 200 and the bridge of the nose 10 has an extremely low propagation speed and a very short wavelength, requiring a very short propagation path. Therefore, by detecting the elastic wave to determine the contact position between the nose pad 200 and the bridge of the nose 10, the elastic wave sensor 300 can be easily miniaturized, facilitating its installation on the nose pad 200. Second, the elastic wave propagates along the solid surface of the elastic wave sensor 300, and its extremely slow propagation speed allows the time-varying signal to be fully represented on the crystal substrate surface at a given instant. As the elastic wave signal travels between the input and output terminals of the elastic wave sensor 300, it is easy to sample and transform the signal, giving the elastic wave sensor 300 great flexibility and enabling more accurate detection of the contact position between the nose pad 200 and the bridge of the nose 10. Third, the elastic wave sensor 300 has extremely high temperature stability, strong radiation resistance, and a large dynamic range, which helps ensure the stability of the detection results.

[0055] Furthermore, in this embodiment, multiple elastic wave sensors 300 are provided, and these multiple elastic wave sensors 300 are spaced apart around the nose pad 200. When the nose pad 200 initially contacts the nose, the weight of the smart glasses itself will exert pressure on the contact point, thereby generating elastic waves. Since the multiple elastic wave sensors 300 are at different distances from the center of the wave source, the time or intensity of the received vibration waves will vary. Based on the time difference or intensity difference of the received waveforms, the position of the wave source can be accurately calculated, thereby determining the contact point between the nose and the nose pad 200, providing a control basis for the controller to control the driving process of the drive device. Preferably, the number of elastic wave sensors 300 is 3 to 5. Without loss of generality, the elastic wave sensors 300 can be arranged around the periphery of the nose pad 200, so that multiple elastic wave sensors 300 can surround the outer periphery of the target contact position 210.

[0056] Furthermore, in this embodiment, the elastic wave sensor 300 is adhered to the nose pad 200. That is, the elastic wave sensor 300 is fixedly connected to the nose pad 200 by adhesive bonding, which is convenient to manufacture and reliable in connection, ensuring the detection accuracy of the elastic wave sensor 300, thereby ensuring the reliability of adjusting the contact position between the nose pad 200 and the user's nose bridge 10. Of course, in other embodiments, the elastic wave sensor 300 may also be embedded in the nose pad 200 or screwed to the nose pad 200.

[0057] Furthermore, in this embodiment, a first rotating shaft 400 is provided between the nose pad 200 and the glasses body 100. The first rotating shaft 400 extends horizontally, and the driving device includes a first motor for driving the nose pad 200 to rotate around the first rotating shaft 400. It can be understood that the smart glasses include two nose pads 200, respectively used to contact the opposite sides of the wearer's nose bridge 10. Without loss of generality, two first rotating shafts 400 are provided, with the upper end of one nose pad 200 correspondingly rotatably connected to one first rotating shaft 400. The axial direction of the first rotating shaft 400 is parallel to the width direction of the nose pad 200 in the horizontal direction, to facilitate the connection between the nose pad 200 and the first rotating shaft 400, and to ensure the reliability of the nose pad 200's rotation. A single first motor can be provided, with its output end connected to two nose pads 200 via different transmission structures, allowing the first motor to simultaneously drive both nose pads 200 to rotate around their corresponding first rotating shafts 400. Alternatively, two first motors can be provided, each driving a nose pad 200 to rotate around its corresponding first rotating shaft 400. In this way, the two nose pads 200 rotate in opposite directions around their respective shafts, causing them to move closer together or further apart. When the two nose pads 200 move closer together, they can clamp tightly onto the wearer's nose bridge 10; when they move further apart, they can fit more loosely against the wearer's nose bridge 10. Furthermore, a single nose pad 200 can be driven to rotate, causing it to expand outwards or contract inwards on one side of the nose bridge 10, allowing it to better fit the corresponding side of the nose bridge 10. Of course, in other embodiments, the first rotating shaft 400 may be rotatably connected to the glasses body 100, the nose pad 200 may be fixedly connected to the first rotating shaft 400, and the first motor may be used to drive the first rotating shaft 400 to rotate around the axis, so as to drive the nose pad 200 to rotate.

[0058] Furthermore, in this embodiment, a second rotating shaft 500 is provided between the nose pad 200 and the glasses body 100. The second rotating shaft 500 extends vertically, and the driving device further includes a second motor for driving the nose pad 200 to rotate around the second rotating shaft 500. Similarly, two second rotating shafts 500 are provided, with one nose pad 200 rotatably connected to one corresponding second rotating shaft 500. Only one second motor can be provided, with its output end connected to two nose pads 200 via different transmission structures, so that the second motor can simultaneously drive two nose pads 200 to rotate around their corresponding second rotating shafts 500; alternatively, two second motors can be provided, with one second motor correspondingly driving and connected to one nose pad 200 to drive the corresponding nose pad 200 to rotate around its corresponding second rotating shaft 500. The first rotating shaft 400 and the second rotating shaft 500 connected to the same nose pad 200 are relatively fixed. When the second motor drives the nose pad 200 to rotate around the second rotating shaft 500, it simultaneously drives the first rotating shaft 400 to move with the nose pad 200. The nose pad 200 rotates around the second pivot 500, which changes the contact area between the nose pad 200 and the bridge of the nose 10. This increases the contact area, reducing the pressure on the bridge of the nose 10 and thus decreasing the wearer's pressure sensation, improving comfort. Simultaneously, the nose pad 200 fits more snugly against the bridge of the nose 10, increasing friction and preventing it from slipping off, thus improving the stability of the smart glasses. Alternatively, in other embodiments, the second pivot 500 can be rotatably connected to the glasses body 100, the nose pad 200 can be fixedly connected to the second pivot 500, and a second motor can drive the second pivot 500 to rotate around its axis, thereby rotating the nose pad 200.

[0059] This invention also proposes a method for controlling the nose pads of smart glasses, such as... Figure 1 , Figure 3 and Figure 4 As shown, the nose pad control method includes the following steps:

[0060] S10. An electrical signal is acquired by an elastic wave sensor 300 configured on the nose pad 200 of the smart glasses.

[0061] S20. Identify the actual contact position between the nose pad 200 and the bridge of the nose 10 based on the electrical signal;

[0062] S30. Based on the actual contact position and the target contact position 210, control the driving device to drive the nose pad 200 to rotate, so as to adjust the contact position between the nose pad 200 and the bridge of the nose 10 to the target contact position 210.

[0063] It is understood that the nose pad 200 is rotatably connected to the main body of the glasses 100. Rotation of the nose pad 200 relative to the main body of the glasses allows the position of the nose pad 200 contacting the bridge of the nose 10 to be adjusted to the target contact position 210. When the nose pad 200 contacts the bridge of the nose 10 through this target contact position 210, the fit between the nose pad 200 and the bridge of the nose 10 is high, the contact area is large, and the pressure on the bridge of the nose 10 is reduced. In this embodiment, when the user wears the smart glasses, after the nose pad 200 contacts the bridge of the nose 10, the weight of the smart glasses exerts pressure on the contact point, generating an elastic wave. The elastic wave sensor 300 can receive the elastic wave, thereby detecting the actual contact position between the nose pad 200 and the bridge of the nose 10. The controller compares the actual contact position with the target contact position 210 to obtain the corresponding control command, controlling the drive device to rotate, thereby adjusting the contact position between the nose pad 200 and the bridge of the nose 10 to the target contact position 210. This will improve the user's wearing comfort.

[0064] Furthermore, in this embodiment, multiple elastic wave sensors 300 are arranged at intervals around the nose pad 200, and step S20 includes:

[0065] S21. Based on the time difference and / or intensity difference between the electrical signals of the corresponding different elastic wave sensors 300, identify the actual contact position between the nose pad 200 and the bridge of the nose 10.

[0066] It is understandable that when the nose pad 200 initially contacts the nose, the weight of the smart glasses themselves will exert pressure on the contact point, generating elastic waves. Since the multiple elastic wave sensors 300 are at different distances from the wave source center, the time or intensity of the received vibration waves will vary. Based on the time difference or intensity difference of the received waveforms, the position of the wave source can be accurately calculated, thereby determining the contact point between the nose and the nose pad 200. This provides a control basis for the controller to control the driving process of the drive device, ensuring the reliability of the controller's control. Preferably, the number of elastic wave sensors 300 is 3 to 5. Without loss of generality, the elastic wave sensors 300 can be arranged around the periphery of the nose pad 200, so that multiple elastic wave sensors 300 can surround the outer periphery of the target contact position 210.

[0067] Further, in this embodiment, step S30 includes:

[0068] S31. Based on the actual contact position and the target contact position 210, obtain the rotation amount of the nose pad 200;

[0069] S32. Based on the amount of rotation to be achieved, control the driving device to drive the nose pad 200 to rotate.

[0070] In this embodiment, the controller compares the actual contact position and the target contact position 210 to analyze the amount of rotation required for the nose pad 200 to change from the actual contact position to the target contact position 210. The drive device drives the nose pad 200 to rotate accordingly, ultimately allowing the nose pad 200 to contact the nose bridge 10 through the target contact position 210. Alternatively, in other embodiments, the controller may obtain the rotation direction of the nose pad 200 based on the actual contact position and the target contact position 210, and control the drive device to drive the nose pad 200 to rotate in that direction. The elastic wave sensor 300 continuously monitors the actual contact position of the nose pad 200 until the actual contact position of the nose pad 200 changes to the target contact position 210, at which point the drive device stops operating.

[0071] Furthermore, in this embodiment, a first rotating shaft 400 is provided between the nose pad 200 and the glasses body 100. The first rotating shaft 400 extends in a horizontal direction. The driving device includes a first motor, which is used to drive the nose pad 200 to rotate around the first rotating shaft 400. The amount to be rotated includes the amount to be rotated around the first rotating shaft 400.

[0072] Step S32 includes:

[0073] S321. Based on the amount to be flipped, control the first motor to drive the nose pad 200 to flip around the first rotating shaft 400 by the amount to be flipped.

[0074] It is understood that the smart glasses include two nose pads 200, which are used to contact the opposite sides of the wearer's nose bridge 10. Without loss of generality, there are two first rotating shafts 400, with the upper end of one nose pad 200 rotatably connected to one of the first rotating shafts 400. The axis of the first rotating shaft 400 is parallel to the width direction of the nose pad 200 in the horizontal direction, so as to facilitate the connection between the nose pad 200 and the first rotating shaft 400 and ensure the reliability of the nose pad 200's rotation. A single first motor can be provided, with its output end connected to the two nose pads 200 through different transmission structures, so that the first motor can simultaneously drive the two nose pads 200 to rotate around their corresponding first rotating shafts 400. Alternatively, there can be two first motors, with one motor correspondingly driving and connected to one nose pad 200 to drive the corresponding nose pad 200 to rotate around its corresponding first rotating shaft 400. Thus, the controller controls the first motor to rotate, causing the two nose pads 200 to rotate in opposite directions around two axes. This allows the two nose pads 200 to move closer together or further apart. When the two nose pads 200 move closer together, they can clamp firmly onto the wearer's nose bridge 10. When they move further apart, the nose pads 200 can fit more loosely against the wearer's nose bridge 10. Alternatively, one nose pad 200 can be individually rotated, expanding outwards or contracting inwards on one side of the nose bridge 10 to better fit the corresponding side of the nose bridge 10. When the controller controls the first motor to rotate the nose pads 200 according to the desired rotation amount, the contact position between the nose pads 200 and the nose bridge 10 is adjusted to the target contact position 210, achieving comfortable wearing of the smart glasses. Of course, in other embodiments, the first rotating shaft 400 may be rotatably connected to the glasses body 100, the nose pad 200 may be fixedly connected to the first rotating shaft 400, and the controller may control the first motor to drive the first rotating shaft 400 to rotate around the axis, so as to drive the nose pad 200 to rotate.

[0075] Furthermore, in this embodiment, a second rotating shaft 500 is provided between the nose pad 200 and the glasses body 100. The second rotating shaft 500 extends in a vertical direction. The driving device also includes a second motor, which is used to drive the nose pad 200 to rotate around the second rotating shaft 500. The amount to be rotated also includes the amount to be rotated around the second rotating shaft 500.

[0076] Step S32 further includes:

[0077] S322. Based on the amount to be rotated, control the second motor to drive the nose pad 200 to rotate around the second rotating shaft 500 by the amount to be rotated.

[0078] Similarly, two second rotating shafts 500 are provided, with one nose pad 200 rotatably connected to one of the second rotating shafts 500. Only one second motor can be provided, with its output end connected to both nose pads 200 via different transmission structures, so that the second motor can simultaneously drive both nose pads 200 to rotate around their corresponding second rotating shafts 500; alternatively, two second motors can be provided, with one second motor correspondingly driving and connecting to one nose pad 200 to drive the corresponding nose pad 200 to rotate around its corresponding second rotating shaft 500. The first rotating shaft 400 and the second rotating shaft 500 connected to the same nose pad 200 are relatively fixed. When the second motor drives the nose pad 200 to rotate around the second rotating shaft 500, it simultaneously drives the first rotating shaft 400 to move with the nose pad 200. The controller controls the nose pad 200 to rotate around the second pivot 500, which changes the contact area between the nose pad 200 and the bridge of the nose 10. This increases the contact area, reducing the pressure on the bridge of the nose 10 and thus decreasing the wearer's pressure sensation, improving comfort. Simultaneously, the nose pad 200 fits more snugly against the bridge of the nose 10, increasing friction and preventing it from slipping off, thus improving the stability of the smart glasses. Alternatively, in other embodiments, the second pivot 500 can be rotatably connected to the glasses body 100, the nose pad 200 can be fixedly connected to the second pivot 500, and the controller can control a second motor to drive the second pivot 500 to rotate around its axis, thereby rotating the nose pad 200.

[0079] The controller can control the first motor and the second motor sequentially or simultaneously. By driving the nose pad 200 to flip through the first motor and the nose pad 200 to rotate through the second motor, the contact position between the nose pad 200 and the bridge of the nose 10 can be adjusted to the target contact position 210 more conveniently and accurately, making the smart glasses more comfortable to wear.

[0080] Furthermore, in this embodiment, after step S30, the method further includes:

[0081] S40. Again, the contact position between the nose pad 200 and the bridge of the nose 10 after rotation is identified by the electrical signal of the elastic wave sensor 300, and it is determined whether the contact position has been adjusted to the target contact position 210.

[0082] If so, proceed as follows:

[0083] S50, Adjustment complete;

[0084] If not, repeat steps S31 to S32.

[0085] In this embodiment, the adjustment ends only when the controller analyzes and determines that the contact position between the nose pad 200 and the bridge of the nose 10 is the target contact position 210 and confirms that the nose pad 200 is adjusted in place. At this time, both the first motor and the second motor stop operating. This ensures the reliability of the adjustment result, thereby helping to ensure the wearer's comfort.

[0086] Furthermore, in this embodiment, after step S50, the method further includes:

[0087] S60. Memory the current position of the nose pad 200 so that when the device is powered on next time, the drive device is controlled to rotate the nose pad 200 to the current position.
