[0045] Embodiment one

[0046] The present embodiment provides an automatic righting system applied to glasses, which can push the glasses to move when the glasses are tilted or sliding down, without the need for the user to manually push the glasses, and can realize automatic righting of the glasses. It should be noted that the glasses in the present embodiment are smart glasses such as VR glasses, AR glasses, XR glasses, etc.

[0047] As shown in Figures 1 to 3 The automatic righting system includes a discrimination calibration module, a righting module 2 and a controller.

[0048] The calibration module includes a distance sensing unit 11, which is located at the front end of the glasses, as shown in the figure. Figure 1 The distance sensing unit 11 is specifically located at the front surface of the glasses frame. The distance sensing unit 11 is used to obtain the distance between the distance sensing unit 11 and the first feature position. The first feature position can be a point on the user's face that is easy to obtain, such as the user's nose tip, nose bone, eyebrow, etc. Preferably, the first feature position is preferably a point on the user's face that does not change. In this embodiment, the distance sensing unit 11 can be a distance sensor or a camera.

[0049] The righting module 2 is used to push up the glasses that have slipped down, so that the glasses are in the appropriate position. Specifically, the righting module 2 includes a push-up air cushion 21, which automatically expands after being powered on. The push-up air cushion 21 is installed at the front end of the glasses, specifically between the glasses frame and the user's nose, so that when the push-up air cushion 21 expands, the user's nose can be used as a support point to push the glasses frame upwards. In this embodiment, the push-up air cushion 21 is powered by a battery in the glasses. In some embodiments, the push-up air cushion 21 is installed at the nose pad groove of the glasses frame. The lower surface of the glasses frame has a nose pad groove with a shape consistent with the nose, which is used to be clamped on the nose. The push-up air cushion 21 is installed at the nose pad groove to better push the glasses frame to move.

[0050] The controller is electrically connected to the distance sensing unit 11 and the push-up air cushion 21. The controller is used to control the opening and closing of the push-up air cushion 21 according to the distance signal of the distance sensing unit 11 to right the glasses. Specifically, when the controller determines that the distance between the distance sensing unit 11 and the first feature position obtained by the distance sensing unit 11 is not the initial distance and is greater than or equal to the distance to be righted, it indicates that the glasses need to be righted. At this time, the push-up air cushion 21 is controlled to start, so that the push-up air cushion 21 expands to push the glasses frame upwards. In the process of moving upwards, the controller obtains the distance between the distance sensing unit 11 and the first feature position in real time. When the distance is equal to the initial distance, it indicates that the glasses have been righted in place. At this time, the controller controls the push-up air cushion 21 to close, thereby achieving the automatic righting of the glasses. It should be noted that the initial distance is the distance between the distance sensing unit 11 and the first feature position when the glasses are in the appropriate position on the user's face. The distance to be righted is the distance between the distance sensing unit 11 and the first feature position when the glasses frame has slipped down to the position that needs to be righted. In this embodiment, the user can set the initial distance and the distance to be righted, that is, the user can set the comfortable position of the glasses and the position that needs to be righted. Different users can have different settings.

[0051] The automatic righting system provided in the embodiment acquires the distance between the automatic righting system and the first feature position through the distance sensing unit 11, and transmits the distance to the controller. The controller determines whether to control the upper pushing air cushion 21 to start according to the distance, and controls the upper pushing air cushion 21 to start when the glasses need to be righted. The upper pushing air cushion 21 expands to push the glasses frame upward, and the controller controls the upper pushing air cushion 21 to close after the glasses are moved to a suitable position, so that the glasses are automatically righted, and the user does not need to manually push the glasses, thereby improving the convenience of righting the glasses.

[0052] Optionally, as shown in Figure 1 , the discrimination calibration module further includes a touch sensing unit 12. The touch sensing unit 12 is located at the tail end of the glasses, and is specifically installed on the temple of the glasses and in contact with the face of the user. The touch sensing unit 12 is triggered by sliding, that is, when the touch sensing unit 12 senses that it moves relative to the face of the user, it can be automatically triggered, and the touch sensing unit 12 can monitor the sliding distance thereof relative to the second feature position, that is, the touch sensing unit 12 can monitor the sliding distance thereof when sliding on the face of the user. The controller is electrically connected to the touch sensing unit 12 and is used to acquire the sliding distance of the touch sensing unit 12, and realizes the control of the upper pushing air cushion 21 in combination with the sliding distance and the distance signal. In the embodiment, the touch sensing unit 12 can be a touch sensor.

[0053] It should be noted that the second feature position is the position of the face of the user, and in some embodiments, when the glasses are in a comfortable position, the position of the face of the user in contact with the touch sensing unit 12 is the second feature position. It should also be noted that the manner in which the touch sensing unit 12 acquires the sliding distance can refer to the manner in which the touch display panel acquires the sliding length of the user's finger. The touch sensing unit 12 is equivalent to the touch display panel, and the skin at the second feature position is equivalent to the finger. This embodiment will not be described here.

[0054] In some embodiments, the controller can control when to reduce the inflation rate of the upper pushing air cushion 21 according to the sliding distance. For example, during the upward movement of the glasses, when the distance of the reverse movement of the glasses is 60% of the sliding distance, the controller controls the inflation rate of the upper pushing air cushion 21 to decrease, so as to prevent the situation of over-righting due to too large inflation rate.

[0055] Optionally, as shown in Figure 1 , a plurality of distance sensing units 11 are provided to ensure the accuracy of the distance signal. The plurality of distance sensing units 11 are arranged at intervals on the outer surface of the glasses frame. The outer surface of the glasses frame is specifically the surface of the glasses frame that does not contact the face of the user. The controller can determine whether the glasses reach the righting position according to the plurality of distance signals of the plurality of distance sensing units 11, so as to prevent the situation of misjudgment. Figure 1In this embodiment, the distance sensing units 11 are provided in three, two of which are respectively arranged at the parts below the two lenses close to the nose, and one is arranged on the upper surface of the frame.

[0056] As shown in Figure 2 and Figure 3 , the righting module 2 further comprises a plurality of clamping air cushions 22. Part of the plurality of clamping air cushions 22 is installed on the inner side of one of the legs of the glasses, that is, between the leg and the face of the user; the other part is installed on the inner side of the other leg of the glasses. The controller controls the plurality of clamping air cushions 22 and is used to control the opening and closing of the clamping air cushions 22. When the clamping air cushions 22 are inflated, the distance between the leg and the face of the user increases, and the distance between the two legs increases. Under the action of the deformation force of the leg, the two legs clamp the face, so that the entire glasses can be firmly fixed on the face of the user. The clamping air cushions 22 can be used in cooperation with the upward air cushions 21. When the upward air cushions 21 right the glasses to a comfortable position, the clamping air cushions 22 are started to enable the glasses to be better fixed in the comfortable position. In this embodiment, as shown in Figure 2 and Figure 3 , two clamping air cushions 22 are arranged on each leg.

[0057] The automatic righting system provided in this embodiment can realize automatic righting of the glasses, has a simple structure and high reliability, and can improve the firmness of the user wearing the glasses by arranging the clamping air cushions 22.

[0058] Embodiment Two

[0059] This embodiment provides a pair of glasses. As shown in Figures 1 to 3 , the glasses comprise a frame 10, a leg 20, and the automatic righting system of embodiment one. The glasses in this embodiment can be AR glasses, VR glasses, or XR glasses, etc., and this embodiment does not limit the same.

[0060] In this embodiment, the distance sensing units 11 and the upward air cushions 21 are both installed on the frame 10, and the controller is arranged in the frame 10 or the leg 20. The glasses further comprise a battery and a control button. The battery is used to provide electric energy for the distance sensing units 11, the upward air cushions 21, and the controller. The control button can be used to input a setting instruction.

[0061] The glasses provided by the embodiment comprise an automatic righting system. The automatic righting system acquires a distance between the automatic righting system and a first feature position through a distance sensing unit 11, and transmits the distance to a controller. The controller determines whether to control a push-up air cushion 21 to start according to the distance, and controls the push-up air cushion 21 to start when the glasses need to be righted. The push-up air cushion 21 expands to push the frame of the glasses upwards, and the controller controls the push-up air cushion 21 to close after the glasses are moved to a suitable position, so that the automatic righting of the glasses is realized, the user does not need to manually push the glasses, and the convenience of righting the glasses is improved.

[0062] Embodiment three

[0063] The embodiment provides an automatic righting method applied to the automatic righting system in the embodiment one. As shown in the figure, Figure 4 the automatic righting method comprises the following steps:

[0064] S1, acquiring an initial distance, the initial distance being a distance recorded by the distance sensing unit 11 between the distance sensing unit 11 and the first feature position when the glasses are in a comfortable position.

[0065] The glasses in the comfortable position means that the glasses are worn on the face of the user, and the user feels comfortable at this position. The position can be set by the user. The first feature position can be a point on the face of the user which is easy to acquire, such as the tip of the nose, the nasal bone, the eyebrow, etc. Preferably, the first feature position is preferably a point on the face of the user which does not change. It should be noted that the initial distance is acquired or set by the controller.

[0066] Optionally, in the embodiment, after the initial distance is acquired, in order to improve the processing speed, the controller can convert the initial distance into an ADC value, and define the value as a threshold threshold alpha.

[0067] S2, acquiring a first distance, the first distance being a distance recorded by the distance sensing unit 11 between the distance sensing unit 11 and the first feature position at the current time.

[0068] In the embodiment, the first distance can be equal to the initial distance, that is, the distance recorded by the distance sensing unit 11 when the glasses do not slide down. It should be noted that the first distance is acquired by the controller.

[0069] S3, determining whether the first distance is greater than or equal to a to-be-righting distance. If yes, step S4 is performed, and if no, step S5 is performed.

[0070] The standby distance is the distance between the distance sensor unit 11 and the first feature position when the frame of the glasses is lowered to the standby position, which can be set by the user. When the first distance is greater than or equal to the standby distance, it indicates that the frame of the glasses has been lowered to the position that needs to be supported, and at this time, the controller can control the start of the upward air cushion 21. It should be noted that the standby distance is obtained or set by the controller.

[0071] In this embodiment, after obtaining the standby distance, the controller can convert the standby distance into an ADC value to improve processing speed, and define the value as a threshold value B. When the ADC value corresponding to the first distance triggers the threshold value B, the controller controls the start of the upward air cushion 21.

[0072] S4, controlling the opening and closing of the upward air cushion 21 according to the first distance and the initial distance, so that the upward air cushion 21 expands to support the glasses.

[0073] The above supporting module 2 is used to push the glasses upwards to make the glasses in a suitable position. Specifically, the supporting module 2 includes an upward air cushion 21, which automatically expands after being powered on, and is installed at the front end of the glasses, specifically between the frame and the user's nose, so that when the upward air cushion 21 expands, it can push the frame of the glasses upwards with the user's nose as the support point. In this embodiment, the upward air cushion 21 is powered by a battery in the glasses. In some embodiments, the upward air cushion 21 is installed at the nose groove of the glasses frame. The lower surface of the frame has a nose groove with the same shape as the nose, which is used to be clamped on the nose, and the upward air cushion 21 is installed at the nose groove to better push the frame to move.

[0074] S5, executing step S3 after a preset time length.

[0075] In step S5, the controller controls the cyclic execution of steps S3 and S4 to periodically detect whether the frame needs to be supported. The preset time length can be set according to actual needs, such as 0.1 seconds, 0.5 seconds, 1 second, etc., which is not limited in this embodiment.

[0076] The automatic supporting method of the automatic supporting system provided in this embodiment acquires the distance between the distance sensor unit 11 and the first feature position, and transmits the distance to the controller. The controller determines whether to control the start of the upward air cushion 21 according to the distance, and controls the start of the upward air cushion 21 when the glasses need to be supported. The expansion of the upward air cushion 21 can push the frame of the glasses upwards, and after moving to a suitable position, the controller controls the closing of the upward air cushion 21, realizing the automatic supporting of the glasses without the need for the user to manually push the glasses, improving the convenience of supporting the glasses.

[0077] Optionally, step S4 includes:

[0078] S41, control the upper push air cushion 21 to open, and record the real-time distance between the first characteristic position and the real-time distance through the distance sensing unit 11.

[0079] In the process of supporting, the distance sensing unit 11 needs to record the real-time distance between the first characteristic position and the real-time distance to determine whether the frame is right to the position. In this embodiment, the collection interval or recording interval of the distance sensing unit 11 can be set according to actual needs, such as 0.1 seconds, 0.5 seconds, 1 second, etc. This embodiment does not limit it. In order to prevent over-supporting, the collection interval or recording interval should not be too large.

[0080] S42, when the real-time distance is equal to or less than the initial distance, control the upper push air cushion 21 to close.

[0081] In step S42, when the real-time distance is less than or equal to the initial distance, it means that the frame is right to the position after supporting, and is located in a comfortable position. At this time, the controller can control the upper push air cushion 21 to close to complete the righting of the glasses.

[0082] Optionally, when the calibration module includes a touch sensing unit 12, the automatic righting method includes the following steps:

[0083] Obtain the sliding distance, which is the distance monitored by the touch sensing unit 12 when the glasses are slid from the comfortable position to the position to be supported relative to the second characteristic position.

[0084] It should be noted that when the glasses start to slide, the touch sensing unit 12 monitors the distance between the second characteristic position in real time until the controller controls the upper push air cushion 21 to start. The distance recorded before the upper push air cushion 21 starts is the sliding distance. In step S4, the controller immediately obtains the sliding distance. The second characteristic position is the position of the user's face. In some embodiments, when the glasses are in a comfortable position, the position of the user's face that contacts the touch sensing unit 12 is the second characteristic position.

[0085] In step S4, when the touch sensing unit 12 moves reversely by a distance of 60% of the sliding distance, the inflation rate of the upper push air cushion 21 is reduced.

[0086] Wherein, the reverse movement of the touch sensing unit 12 can be considered as the movement direction of the touch sensing unit 12 opposite to the sliding direction when the glasses are slid downward. In the process of righting, when the touch sensing unit 12 moves reversely by a distance of 60% of the sliding distance, it means that the glasses will reach the comfortable position. At this time, if the inflation rate of the upper push air cushion 21 is still large, it is more likely to over-support, therefore, the controller can control the inflation rate of the upper push air cushion 21 to reduce, so that the glasses slowly move to the comfortable position.

[0087] Optionally, when the righting module 2 comprises a plurality of clamping air cushions 22, after the glasses are righted, the automatic righting method further comprises:

[0088] Controlling the clamping air cushions 22 to start, the clamping air cushions 22 expand to increase the distance between the two legs, thereby being able to improve the firmness of the glasses on the user's face, so that the glasses will not slide down again in a short time.

[0089] The above embodiments only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above embodiments. Various changes and modifications can be made without departing from the spirit and scope of the present application, and these changes and modifications all fall within the scope of the present application.
