Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an intelligent glasses provided in an embodiment of the present application. The embodiment of the application provides an intelligent glasses 1, the intelligent glasses 1 can be divided into augmented Reality (Augmented Reality, AR), virtual Reality (VR), mixed Reality (MR), augmented Reality (XR) and the like according to different display types, wherein the XR comprises AR, VR and MR, the XR is through corresponding hardware equipment, and combines various software technical means to fuse Virtual contents with a real scene, a Virtual world like dreaminess is built in an XR Virtual studio, and cool visual effects can be brought to users.

Illustratively, the smart glasses 1 include a lens assembly 10 and a temple 20.

The lens assembly 10 is used to display a picture, for example, the lens assembly 10 may include an optical waveguide or lens, an optical engine, etc. (not shown). Temples 20 are rotatably connected to opposite sides of lens assembly 10, and temples 20 are adapted to provide support in conjunction with the lens support of lens assembly 10 when worn by a user. Each smart glasses 1 includes two temples 20, and the two temples 20 are symmetrically arranged with the central axis of the lens assembly 10 as a symmetry axis. In the unfolded state of the smart glasses 1, the temples 20 are rotatably connected to the end sides of the lens assembly 10, and the rotatable angle range of the temples 20 may be 0 ° to 90 °, so that the smart glasses 1 are worn by a user in the unfolded state and are convenient to store in the folded state.

The diffractive optical waveguide smart glasses require total reflection transmission of optical signals in the lens to ensure utilization of the optical signals, and therefore use of flat high refractive index glass is required. With the development of intelligent glasses and the demands of users, users with normal eyesight are not limited to use the intelligent glasses, and general solutions of intelligent glasses suitable for users with myopia and hyperopia are continuously sought.

In the related art, a myopia lens or a presbyopic lens is assisted in a glasses frame of the glasses, so that different users wear different glasses, and the universality is poor.

To reduce the occurrence of the above, embodiments of the present application provide improvements to the lens assembly 10, as will be described below with reference to the accompanying drawings.

For example, please refer to fig. 1 in combination with fig. 2 to fig. 4, fig. 2 is a first structural schematic diagram of the lens assembly according to the embodiment of the present application, fig. 3 is a first structural schematic diagram of the lens assembly shown in fig. 2, and fig. 4 is a second structural schematic diagram of the lens assembly shown in fig. 2. The lens assembly 10 includes a lens 11, a first piezoelectric portion 12, and a first filler portion 13. The mirror assembly 10 may also include an optical engine (not shown) for emitting an illumination beam in an emission path and also for modulating the illumination beam into image light and for transmitting the image light to a projection imaging system, such as mirror 11, for projection imaging the image light by the projection imaging system. The lens 11 may be referred to as an optical waveguide, and the lens 11 has a transmission region and an entrance region (not identified in the figures). In AR glasses, it is critical that the light be transmitted without loss or leakage, and that the light be reflected back and forth in the waveguide, as if it were a snake, without being transmitted. After the optical machine completes the imaging process, the waveguide couples light into its own glass substrate, and the light is transmitted to the front of the eye and released by the principle of total reflection. The above is also the imaging principle of the smart glasses 1.

The lens 11 has an inner side M facing the human eye and an outer side N opposite to the inner side M, which is for convenience of description and should not be construed as limiting the lens 11. The first piezoelectric portion 12 is attached to the inner side M of the lens 11, and the first piezoelectric portion 12 is configured to deform in an energized state to form different curvatures. The first filling portion 13 is disposed between the first piezoelectric portion 12 and the lens 11 to fill the deformed portion when the first piezoelectric portion 12 is deformed, or the first filling portion 13 is used to provide support when the first piezoelectric portion 12 is deformed to support the deformed shape of the first piezoelectric portion 12.

In the lens assembly 10 provided by the embodiment of the application, the first piezoelectric portion 12 is arranged on the inner side M of the lens 11, and the first piezoelectric portion 12 deforms to form different curvatures in the electrified state, so that diopter requirements of myopia and hyperopia users are met, and universality of the intelligent glasses 1 is improved. The first piezoelectric part 12 and the lens 11 are adhered into a whole, so that on one hand, the reflection times of light rays can be reduced, and on the other hand, materials are concentrated together, so that the thickness of the lens assembly 10 is reduced, and the installation procedure is reduced.

It will be appreciated that the first piezoelectric portion 12 and the first filler portion 13 are transparent so that a user can view the image presented on the lens 11 through the first piezoelectric portion 12 and the first filler portion 13. For example, the first piezoelectric portion 12 may be made of a transparent piezoelectric ceramic material, so that the first piezoelectric portion 12 can deform under the driving of an electrical signal without blocking the user from viewing the image presented on the lens 11. Similarly, the first filling portion 13 is made of a polymer transparent filler, and the polymer transparent filler mainly serves as a support, that is, when the first piezoelectric portion 12 is deformed, the deformed portion is filled to support the deformed first piezoelectric portion 12, so that the first piezoelectric portion 12 maintains the deformed shape, and further, requirements on diopters of different users are met. In addition, the refractive indexes of the first piezoelectric portion 12 and the first filling portion 13 are the same, so that the phenomenon that the lens 11 is dazzled due to multiple refraction and reflection of light in a module formed by the first piezoelectric portion 12, the first filling portion 13 and other components can be prevented.

Wherein the deformation of the first piezoelectric portion 12 is achieved by applying a voltage through the electrodes. For example, please refer to fig. 1 to 4 and fig. 5 and 6, fig. 5 is a first structural schematic diagram of the first piezoelectric portion and the first electrode in the lens assembly provided in the embodiment of the present application, and fig. 6 is a second structural schematic diagram of the first piezoelectric portion and the first electrode in the lens assembly provided in the embodiment of the present application. The lens assembly 10 further includes a first electrode 14 and a second electrode 15. The first electrode 14 is arranged at an edge of the first piezoelectric part 12 facing away from the lens 11, for example, around the periphery. The second electrode 15 is disposed at an edge of the first voltage portion 12 facing the lens 11, for example, may be disposed around the edge. The second electrode 15 cooperates with the first electrode 14 to drive the first voltage portion 12 to deform. It can be understood that the first electrode 14 and the second electrode 15 are respectively powered, and a voltage is applied between the first electrode 14 and the second electrode 15, so that the first piezoelectric portion 12 is deformed, and the deformation degree of the first piezoelectric portion 12 is greater as the voltage is greater; in addition, the directions of the voltages are different, so that the deformation directions of the first piezoelectric portions 12 are also different, and as long as the voltage directions and the voltage magnitudes are controlled, the first piezoelectric portions 12 can be controlled to form concave lenses or convex lenses, so that the requirements of different diopters of near-sighted users or far-sighted users are met, and the universality of the lens assembly 10 is improved.

It should be noted that the lens 11 may have an edge area and a center area, the edge area may be disposed around the center area, and the edge area and the center area together form the lens 11. Also, the edge area and the center area are areas artificially delimited for convenience of description, and should not be construed as limiting the lens 11. In application, the edge area may have a smaller dimension than the center area for the lens 11 viewed from the same direction, e.g., the width of the edge area may be smaller than the width of the center area as viewed from the width direction of the lens 11. The first piezoelectric portion 12 may cover the lens 11 before and after deformation, that is, the size of the first piezoelectric portion 12 may be greater than or equal to the size of the lens 11, so that a user may first perform diopter adjustment through the first piezoelectric portion 12 before viewing a picture presented by the lens 11, and the diopter adjustment area is complete, so that the picture that the user viewing angle can view may meet the requirements, that is, the viewing range is improved, and further the user experience is improved.

The first electrode 14 and the second electrode 15 may each have a ring shape, such as a ring shape of a circle, a square ring shape, or other shapes. Specifically, the shapes of the first electrode 14 and the second electrode 15 may be adapted to the shape of the lens 11, for example, when the lens 11 is square, the shapes of the first electrode 14 and the second electrode 15 may be square ring shapes. The annular first electrode 14 and the second electrode 15 may correspond to each other on two sides of the lens 11, for example, the first electrode 14 and the second electrode 15 are respectively disposed on two side edges of the lens 11, so as to drive the first piezoelectric portion 12 to squeeze or loosen the first filling portion 13 from the edges, so that a central area of the first piezoelectric portion 12 takes a convex or concave curved shape, and the first filling portion 13 performs filling support, and maintains the curved shape of the first piezoelectric portion 12 for use by a far-vision user or a near-vision user.

Illustratively, the size of the portion of the first piezoelectric portion 12 within the annular space of the first electrode 14 or within the annular space of the second electrode 15 is greater than the size of the first electrode 14 or the size of the second electrode 15 in the same direction; in other words, the size of the first piezoelectric portion 12 in the annular space of the first electrode 14 is larger than the size of the first electrode 14 in the same direction, or the size of the first piezoelectric portion 12 in the annular space of the second electrode 15 is larger than the size of the second electrode 15 in the same direction. So that the first piezoelectric portion 12 is in a curved surface with a sufficient size, on the one hand, the range of diopter adjustment for different users can be increased, and on the other hand, the viewable field of view for the users can be ensured.

Fig. 7 is a schematic diagram of a third structure of the first piezoelectric portion and the first electrode in the lens assembly according to the embodiment of the present application, and fig. 8 is a schematic diagram of a fourth structure of the first piezoelectric portion and the first electrode in the lens assembly according to the embodiment of the present application. The first electrode 14 and the second electrode 15 may be integrated electrodes, so as to facilitate manufacturing, and the first electrode 14 and the second electrode 15 may be separate electrodes, so that deformation driving of the first piezoelectric portion 12 may be ensured, and consumable materials may be saved. For example, the first electrode 14 includes a plurality of first sub-electrodes 140, and the plurality of first sub-electrodes 140 are arranged at intervals on one side edge of the first piezoelectric portion 12. The second electrode 15 includes a plurality of second sub-electrodes 150, and the plurality of second sub-electrodes 150 are arranged at intervals on the other side edge of the first piezoelectric portion 12, and each of the second sub-electrodes 150 corresponds to one of the first sub-electrodes 140, so that a voltage is applied between the first sub-electrode 140 and the second sub-electrode 150, so as to drive the first piezoelectric portion 12 to deform.

The first electrode 14 and the second electrode 15 are transparent electrodes to avoid shielding the lens 11, thereby improving the user's viewing experience.

In order to increase the adjustment range of diopter, a double-sided piezoelectric portion may be provided to adjust diopter.

For example, please refer to fig. 1 to 8 in combination with fig. 9 and 10, fig. 9 is a schematic structural diagram of a second structure of the lens assembly according to the embodiment of the present application, and fig. 10 is a schematic structural diagram of another deformed structure of the lens assembly shown in fig. 9. The lens assembly 10 further includes a glass substrate 16, a second piezoelectric portion 17, a second filling portion 18, and a third filling portion 19.

The glass substrate 16 is disposed between the first filling portion 13 and the lens 11 to carry the first filling portion 13. In some embodiments, a glass substrate 16 may be attached to the inner side of the lens 11, and then the first filling portion 13 and the first piezoelectric portion 12 may be sequentially disposed. The thickness of the glass substrate 16 is lower than 0.1mm, and the thickness of the glass substrate 16 is lower than 0.03mm, so that the glass substrate 16 can be attached to the lens 11, the module consisting of the glass substrate 16, the first filling part 13 and the first piezoelectric part 12 is integrated with the lens 11, and ghost images entering eyes can be reduced.

In some embodiments, glass substrate 16 may also serve as a support substrate for the two-sided self-adjusting diopter component. For example, the second piezoelectric portion 17 is disposed between the glass substrate 16 and the lens 11, and the second piezoelectric portion 17 is configured to deform in an energized state to form different curvatures so as to accommodate diopter requirements of different users. Also, the second piezoelectric portion 17 is deformed in the opposite direction to the first piezoelectric portion 12 so that both together provide the diopter required by the user. For example, when the first piezoelectric portion 12 is protruded away from the glass substrate 16, the second piezoelectric portion 17 is protruded away from the glass substrate; for another example, when the first piezoelectric portion 12 is recessed toward the glass substrate 16, the second piezoelectric portion 17 is recessed toward the glass substrate 16.

The second piezoelectric portion 17 and the first piezoelectric portion 12 are adopted to adjust diopter together, so that diopter adjustment range can be increased, user requirements of different myopia degrees or hyperopia degrees can be met, and universality of the intelligent glasses 1 is improved.

It is understood that, for the purpose of maintaining the deformed shape of the second piezoelectric portion 17 when the second piezoelectric portion 17 is deformed, a second filling portion 18 may be provided, the second filling portion 18 being provided between the glass substrate 16 and the second piezoelectric portion 17 to fill and support the deformed portion when the second piezoelectric portion 17 is deformed.

The second piezoelectric portion 17 and the second filling portion 18 are transparent, corresponding to the first piezoelectric portion 12 and the first filling portion 13, so that a user can view the screen presented on the lens 11 through the first piezoelectric portion 12, the first filling portion 13, the glass substrate 16, the second piezoelectric portion 17 and the second filling portion 18. For example, the second piezoelectric portion 17 may be made of a transparent piezoelectric ceramic material, so that the second piezoelectric portion 17 can deform under the driving of an electrical signal without blocking the user from viewing the image presented on the lens 11. Similarly, the second filling portion 18 is made of a polymer transparent filler, and the polymer transparent filler mainly serves as a support, that is, when the second piezoelectric portion 17 is deformed, the deformed portion is filled to support the deformed second piezoelectric portion 17, so that the second piezoelectric portion 17 maintains the deformed shape, and further, requirements of different user diopters are met. In addition, the refractive indexes of the second piezoelectric portion 17 and the second filling portion 18 are the same, and the refractive indexes of the second piezoelectric portion 17 and the first piezoelectric portion 12 are the same, so that the glare phenomenon of the lens 11 caused by multiple refraction and reflection of light in the modules of the second piezoelectric portion 17 and the second filling portion 18 and the first piezoelectric portion 12 and the first filling portion 13 can be prevented.

The third filling portion 19 is provided between the second piezoelectric portion 17 and the lens 11 to fill with the second filling portion 18 from opposite sides of the second piezoelectric portion 17, respectively, when the second piezoelectric portion 17 is deformed, to support the deformation of the second piezoelectric portion 17. It can be understood that if the third filling portion is not provided, when the second piezoelectric portion 17 is deformed, a gap exists between the second piezoelectric portion 17 and the lens 11, which on one hand causes the second piezoelectric portion 17 to be affected by the lens 11 and not reach the predetermined shape, and on the other hand causes a gap between the second piezoelectric portion 17 and the lens 11 to affect the refractive indexes of the second piezoelectric portion 17 and the lens 11.

The material of the third filling portion 19 may be the same as that of the second filling portion 18 and the first filling portion 13, and a polymer transparent filler may be selected. The first filling part 13, the second filling part 18 and the third filling part 19 are used for supporting, and meanwhile, the refractive indexes of the first filling part 13, the second filling part 18 and the third filling part 19 are the same as those of the first piezoelectric part 12 and the second piezoelectric part 17, so that excessive refraction and reflection of light in the whole module can be prevented, and the glare phenomenon caused by the excessive refraction and reflection can be reduced.

The deformation driving of the second piezoelectric portion 17 may be performed by applying a voltage to the electrodes. For example, the first electrode 14 and the second electrode 15 may be disposed at edges of opposite sides of the second piezoelectric portion 17, where the first electrode 14 and the second electrode 15 are opposite, and may each have a ring shape, so that a voltage is applied between the first electrode 14 and the second electrode 15 to drive the second piezoelectric portion 17 to deform. The relative positional relationship between the first electrode 14 and the second electrode 15 and the second piezoelectric portion 17 may refer to the above-mentioned relative positional relationship between the first electrode 14 and the second electrode 15 and the first piezoelectric portion 12, and will not be described here again.

In the related art, the diopter adjusting member and the lens are separately disposed, and when the diffracted light appears in the pupil area, the diopter adjusting member easily reflects light, which causes ghost images to appear in the eye. In the embodiment of the application, the glass substrate 16, the first filling portion 13, the first piezoelectric portion 12, the second piezoelectric portion 17, the second filling portion 18 and the third filling portion 19 are attached to the lens 11, and the first filling portion 13, the second filling portion 18, the third filling portion 19 and the first piezoelectric portion 12 and the second piezoelectric portion 17 have the same refractive index, so that the light does not have multiple reflection phenomena in a uniform substance or a substance with the same refractive index, and the occurrence of ghosts can be reduced. And, the materials are concentrated together, so that the thickness of the lens assembly 10 can be reduced, the weight of the lens assembly 10 is reduced, and the installation procedure is reduced.

In the use process of the user, under the drive of voltages in different directions, the first piezoelectric part 12 and the second piezoelectric part 17 generate diopter changes, such as both protruding away from the glass substrate 16 or both sinking close to the glass substrate 16, so as to form diopter suitable for myopia or hyperopia of the user, and improve the universality of the intelligent glasses 1. The diopter corresponding to the voltage can be corresponding in a quantitative test mode. The user directly adjusts to a proper diopter value through interface input under the condition of knowing the diopter of the user. Or a linear switch, such as a touch control bar (not shown) arranged on the glasses leg 20, adjusts the voltage change in the process of sliding the touch control bar to achieve the proper diopter of the user, and stores the diopter, so that the user can automatically adjust to the diopter requirement of each user when starting the intelligent glasses 1.

Illustratively, the smart glasses 1 include a lens assembly 10, a temple 20, a detection module (not shown), and a manipulation module (not shown). The detection module is used for detecting whether the number of degrees of glasses is set in the control system of the intelligent glasses 1, for example, by inquiring whether corresponding data of the number of degrees of glasses are available. The manipulation module may be a voice module or a touch module. The voice module is used for adjusting the diopter value of the lens assembly 10 according to the voice command of the user so as to adapt to diopter requirements of different users. The touch module is used for adjusting voltage change through touch operation of a user so as to meet diopter requirements of the user.

The process of the user using and controlling the smart glasses 1 may be: when the intelligent glasses 1 are started, the detection module detects whether the glasses degree is set in the control system of the intelligent glasses 1. If so, the user is required to confirm whether the current eyeglass power accords with the eyeglass power of the current user. If so, the intelligent glasses 1 are normally used, such as watching the shadow. And if the glasses degree does not accord with the current glasses degree of the user or the glasses degree is detected not to be set in the control system, diopter adjustment is performed. The diopter adjustment process is as follows: calling diopter setting by voice, and speaking the glasses degree; or invokes the touch module of the temple 20 to linearly adjust the current user's degree of eyeglasses. Then, the number of the diopters controlled by the voice module or the touch control module is matched with the diopters in the stored mapping table, and a control voltage corresponding to the diopters is output to control the lens assembly 10 to form a corresponding diopter requirement, and then normal use processes of the intelligent glasses 1, such as film watching, can be performed.

In the lens component 10 of the intelligent glasses and the intelligent glasses 1 provided by the embodiment of the application, the first piezoelectric part 12 is arranged on the inner side M of the lens 11, and the first piezoelectric part 12 deforms to form different curvatures in the electrified state, so that diopter requirements of myopia and hyperopia users are met, and universality of the intelligent glasses 1 is improved. The first piezoelectric part 12 and the lens 11 are adhered into a whole, so that on one hand, the reflection times of light rays can be reduced, and on the other hand, materials are concentrated together, so that the thickness of the lens assembly 10 is reduced, and the installation procedure is reduced.
