In order to better understand the aspects of the present utility model, the present utility model will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Fig. 1 to 2 show a schematic structural diagram of an AR swimming goggles including an AR display device according to an embodiment of the present utility model, and fig. 2 shows a schematic partial sectional structural diagram of the AR swimming goggles in fig. 1. A schematic structural view of a portion of an AR display device included in an AR swimming goggles is shown in the schematic view shown in fig. 2.

The AR display device may include:

a waveguide lens 5 and a light source module 4;

the light source module 4 is used for outputting projection light to the waveguide lens 5 so as to couple out the projection light after being conducted through total reflection of the waveguide lens 5 to form a projection picture;

the light source module 4 has a first projection mode and a second projection mode, and a projection screen formed by the light source module 4 according to the projection light outputted by the first projection mode is upside down with respect to a projection screen formed by the light outputted by the second projection mode;

the AR display device comprises a first wearing mode and a second wearing mode, and the AR display device rotates 180 degrees relative to the waveguide lens when worn according to the first wearing mode;

when the AR display device is worn according to a first wearing mode, the light source module outputs projection light according to a first projection mode; when the AR display device is worn in the second wearing mode, the light source module outputs projection light in the second projection mode.

It is understood that for the current conventional AR display device, no matter whether the AR display device is actually applied in a specific product like a helmet-structured head-mounted device or glasses, the AR display device has only one wearing mode. Whereas the AR display device of the present utility model has two different wearing modes, namely, a first wearing mode and a second wearing mode, as opposed to the conventional AR display device; also, there is a 180 degree rotation of the waveguide lens 5 when the AR display device is worn in the first wearing mode with respect to the waveguide lens 5 when worn in the second wearing mode, respectively.

Referring to fig. 1 and 2, with fig. 1 and 2 as an example of an AR swimming goggles incorporating the AR display device of the present utility model, assuming that the AR display device in the AR swimming goggles shown in fig. 1 is worn in a first wearing mode, it is apparent that the first waveguide lens 51 corresponds to the left eye of the wearer and the second waveguide lens 52 corresponds to the right eye of the wearer; however, when the AR display device is worn in the second wearing mode, that is, the AR display device is turned 180 degrees, it is obvious that in the AR display device worn in the second wearing mode, the first waveguide lens 51 corresponds to the right eye of the wearer, and the second waveguide lens 52 corresponds to the left eye of the wearer. And the first waveguide lens 51 and the second waveguide lens 52 corresponding to the second wearing mode are both upside down with respect to the state when the first wearing mode is in.

Of course, the above is described with respect to an example in which two waveguide lenses 5 corresponding to the left eye and the right eye of the human eye are included in the AR display device, respectively. But in practical applications there are other types of structures for the waveguide lens 5 of the AR display device.

For example, the waveguide lens 5 of the AR display device corresponding to the left and right eyes of the wearer may be a unitary one-piece lens structure. Then, the display area on the waveguide lens 5 corresponding to the left eye when the AR display device is worn in the first wearing mode, i.e. the display area corresponding to the right eye when the AR display device is worn in the second wearing mode; and a display area on the waveguide lens 5 corresponding to the right eye when the AR display device is worn in the first wearing mode and a display area corresponding to the left eye when the AR display device is worn in the second wearing mode; similarly, the first waveguide lens 51 and the second waveguide lens 52 are both inverted in the second wearing mode with respect to the first wearing mode.

Also for example, an implementation in which only the wearer-side glasses-setting waveguide lens 5 is provided in the AR display device may be also provided. That is, the AR display device performs AR display of the projection image only for the monocular of the wearer. Assume that when the AR display device is worn in the first wearing mode, the waveguide lens 5 of the AR display device is located at a position where projection display is performed on the left eye of the wearer; when the AR display device is worn in the second wearing mode, the waveguide lens may then be flipped to a position corresponding to the projection display of the right eye of the wearer, with the waveguide lens 5 likewise being flipped upside down.

Various structural types of the waveguide lens 5 of the AR display device and the corresponding first and second wearing modes are described above. The projection modes of the light source modules 4 corresponding to the different waveguide lenses 5 in the AR display device will be described in detail below.

As described above, for the first wearing mode and the second wearing mode of the AR display device, there is a 180-degree rotation of the state of the waveguide lens 5, that is, reverse setting occurs both up and down and left and right. For this reason, in order to accommodate this change in the state of the waveguide lens 5 in the present embodiment, the corresponding light source modes also have two different projection modes, respectively.

Take the example of the glasses apparatus including the AR display apparatus shown in fig. 1. If the waveguide lens 5 in the AR display device comprises a first waveguide lens 51 and a second waveguide lens 52. When the AR display device is worn in the first wearing mode, the light source module 4 projects output projection light to the waveguide lens 5 in the first projection mode. It is understood that the case where the light source module 4 outputs the projection light to the waveguide lenses 5 may be divided into the case where the projection light is simultaneously outputted to two waveguide lenses 5 and the case where the projection light is outputted to only one of the waveguide lenses 5.

Assuming that the light source modules 4 simultaneously project projection light to two waveguide lenses 5, the light source modules 4 may include two light source modules at this time, and each light source module 4 outputs the projection light to one of the waveguide lenses 5. When the AR display device is worn in the first wearing mode, the projection images formed by the projection light beams projected onto the first waveguide lens 51 and the second waveguide lens 52 by the light source module 4 are projection images displayed in the forward direction. When the AR display device is worn according to the second wearing mode, because the waveguide lens 5 and the light source module 4 are turned upside down and left and right by 180 degrees, if the light source module outputs projection light to the waveguide lens 5 according to the first projection mode at this time, a projection picture formed by the projection light received by human eyes is obviously an upside-down projection picture. As shown in fig. 3, fig. 3 is a schematic diagram showing the display contrast of the corresponding projection images when the projection modes are not switched in two different wearing modes on the AR display device. Obviously, when the wearing mode of the AR display device is changed and the projection mode is not changed correspondingly, the projected image is inverted and cannot be watched. For this reason, when the AR display device is worn according to the second wearing mode, the light source module 4 displays and outputs the projection light to the waveguide lens 5 according to the second projection mode, so that it is ensured that the AR display device can display a projection screen displayed in the forward direction for the wearer whether it is worn according to the first wearing mode or the second wearing mode.

In another alternative embodiment of the present utility model, even if two waveguide lenses 5 are included in the AR display device, the light source module 4 may output projection light to only one of the waveguide lenses 5 in practical applications. It is assumed that when the AR display device is worn in the first wearing mode, the light source module 4 projects and outputs projection light to only the first waveguide lens 51 in the first projection mode, the second waveguide lens 52 functions as a normal lens only at this time, and the light source module 4 can project and output a projection screen displayed forward to the left eye of the wearer through the first waveguide lens 51 at this time; when the AR display device is worn according to the second wearing mode, the light source module 4 still outputs the projection light to the first waveguide lens 51 according to the second projection mode, but the difference is that the light source module 4 rotates 180 degrees according to the projection light respectively projected and output by the first projection mode and the second projection mode, so that the projection image is inverted up and down, that is, the projection image formed by the projection light conducted and output to the human eye through the first waveguide lens 51 is still forward displayed, and the projection light at the moment is received and displayed by the right eye of the wearer.

It can be understood that, in the above embodiment, the light source module 4 in the AR display device outputs the projection light in the first projection mode and the second projection mode respectively, by changing the projection light output by the light source module 4 itself; in practical applications, the light source module 4 may be connected to a configuration processor, which is used to control the switching of the projection screen outputted by the image source upside down. For the conventional light source module 4, the brightness, color, etc. of the projection light outputted by each pixel point on the light emitting surface of the conventional light source module 4 can be obviously set and changed according to the projection picture actually required to be displayed, so that the projection display of the dynamic projection picture can be realized, and for the light source module 4, the implementation manner of switching between the first projection mode and the second projection mode can be regarded as equivalent to that of dynamically switching and displaying two different projection pictures by the image source. Therefore, in practical application, the processor can control the image source to display projection light according to the mode that the AR display device is actually worn, and display the image source in a switching mode according to two different projection modes. It is seen that the processor in this embodiment is not improved in terms of program, and is in accordance with the protection object of the utility model. For the image source, in this embodiment, the image source itself is utilized to realize the projection function of dynamic projection images, so as to realize the display of two mutually inverted projection images.

The image source in the light source module 4 may be specifically an organic light emitting diode or a micro-nano light emitting diode, which is not specifically limited in the present utility model.

Of course, in practical application, when the AR display device is in the first wearing mode and the second wearing mode, the corresponding projection images are inverted, which is not limited to the above implementation manner.

Taking the above-mentioned AR display device as an example, the AR display device includes two waveguide lenses 5, and each waveguide lens 5 is correspondingly provided with one light source module 4, and the projection images formed by the projection light beams output by the two light source modules 4 are inverted, but when in actual projection display, one of the light source modules 4 can be selected to output the projection light beam according to the mode in which the AR display device is worn. For example, when the AR display device is worn in the first wearing mode, the light source module 4 corresponding to the first waveguide lens 51 is turned on and outputs projection light to the first waveguide lens 51 at this time, so that the human eye can receive the projection screen displayed in the forward direction; and at this time the corresponding light source module 4 of the second waveguide lens 52 is turned off. When the AR display device is worn in the second wearing mode, the light source module 4 corresponding to the first waveguide lens 51 is turned off, and the light source module 4 corresponding to the second waveguide lens 52 is turned on, because the second waveguide lens 52 is turned upside down relative to the first wearing mode, the projection image formed by the projection light transmitted and output through the second waveguide lens 52 is the image displayed in the forward direction, so that the effect that the projection image is displayed in the forward direction in two different wearing modes of the AR display device can be achieved.

It will be appreciated that for the AR display device in which two different projection modes are switched by the two light source modules 4, the image source in each light source module 4 may be connected to a processor, and the image source of one of the light source modules 4 is controlled to be turned on or off by the processor.

In addition, it should be noted that, whether the AR display device performs only monocular projection display or binocular projection display, the light source module 4 performs two different projection modes, and in addition to the above-mentioned projection mode of switching the image sources in the light source module 4 or the projection mode of selectively turning on one of the image sources and turning off the other image source, the present utility model does not exclude two display modes of directly connecting the light source module 4 to the driving motor, and switching the projection screen formed by the projection light finally outputted by the light source module 4 by rotating the driving motor by 180 ° about the central symmetry axis perpendicular to the light emitting surface thereof. In addition, other ways of implementing two different projection displays of the light source module 4 are also possible in the present utility model, which is not meant to be limiting.

The above description is given taking the case where the AR display device has two waveguide lenses 5 as an example, as described above, the two waveguide lenses 5 of the AR display device may be one waveguide lens integrally formed. It can be understood that, for the waveguide lens 5 facing the left and right eyes of the wearer, the left half area and the right half area of the waveguide lens 5 can be respectively equivalent to the waveguide lens 5 of the left and right eyes in the AR display device with the two waveguide lenses 5, the difference is only that the two waveguide lenses 5 are integrally formed or independent, accordingly, when the light source module 4 outputs projection light to the waveguide lens 5 according to two different projection modes, the projection light can also be respectively projected to the left and right two areas of the waveguide lens 5 to output projection light to one area, and when the wearing mode of the AR display device changes, the processor triggers the image source to convert the output projection light, so as to realize the switching of the projection modes; the two light source modules 4 may also be configured to output the projection images upside down, so that the two projection modes may be switched, and the specific principle is similar to the projection of the two projection modes implemented by the light source modules 4 in the above-mentioned AR display device with two waveguide lenses, so that the description is not repeated in this embodiment.

In addition, it is also possible for the AR display device to have only one waveguide lens 5 for one side eye of the wearer. Assuming that when the AR display device is worn according to the first wearing mode, assuming that the waveguide lens 5 is just located at a position corresponding to the left eye of the wearer, then the light source module 4 outputs projection light to the waveguide lens 5 according to the first projection mode, so that the projection light forward displays a projection picture on the left eye of the wearer; when the AR display device is worn in the second wearing mode, the light source module 4 outputs the projection light according to the second projection mode, and the projection screen formed by the outputted projection light is inverted above and below with respect to the projection screen corresponding to the projection light outputted in the first projection mode, so that the AR display device is worn in the second wearing mode, and the wearer can also view the projection screen displayed in the forward direction. Obviously, the two projection modes of the light source module 4 in this embodiment may be realized by switching the light emitting surface of the image source by the processor to output projection light, or may be realized by driving the image source to rotate by the driving motor, which is not repeated in the present utility model.

Based on the above discussion, in practical application, three different display modes are available for the projection image formed by the projection light outputted by the AR display device according to the present utility model.

The first is that the light source module 4 in the AR display device synchronously outputs the projection pictures to the eyes on the left and right sides of the wearer at the same time, and when the wearing mode of the AR display device changes, the projection pictures output to the eyes by the light source module respectively also correspondingly generate inversion changes. Corresponding to an embodiment in which two waveguide lenses or the lenses corresponding to the left eye and the right eye are integrally formed in the AR display device, and the light source module 4 outputs the projection light through the waveguide lens 5 at the same time.

One of the most typical applications of AR display devices for this display mode is to be installed in AR goggles for use. As shown in fig. 1, the AR swimming goggles are generally worn by being fixed on the head of a wearer through an elastic strap; because there is no temple, etc. to clearly distinguish the sign structure of the swimming goggles, the user often wears the AR swimming goggles upside down easily, and once the AR swimming goggles are found to be worn reversely, the user needs to take off and wear again, and the whole process is complicated.

Likewise, for other devices that do not have a distinct distinction between top and bottom and that include an AR display device, the appropriate projection mode may be selected based on the manner in which the AR display device is worn by the wearer, in a similar manner as described above. Therefore, the limitation of wearing modes when the AR display device is worn can be broken through to a certain extent, and the convenience of the AR display device is improved to a certain extent.

In the second display mode of the AR display device, the light source module 4 in the AR display device outputs the projection light to only one waveguide lens 5 or one area of one waveguide lens 5 all the time, when the wearing mode of the AR display device is switched from one wearing mode to another wearing mode, the projection light output by the light source module 4 is changed from being received by one eye to being received by the other eye, that is, the eyes receiving the view projection picture are also switched. Corresponding to an embodiment in which the AR display device is provided with the waveguide lens 5 only for one eye of the wearer, or in which the AR display device is provided with two waveguide lenses 5, the light source module 4 is fixed only to output projection light to one of the waveguide lenses 5 for monocular display.

For many wearers, the vision of the left eye and the right eye is not necessarily identical, but the single-eye vision of some wearers is better because of different reasons such as amblyopia, myopia and even single-eye blindness; obviously, when the wearer uses the AR display device to perform monocular projection display, the wearer can watch the projection picture by adopting the eye at the side with better vision, and obviously can watch a clearer picture. Therefore, when the wearer actually uses the AR display device in this embodiment, a proper wearing mode may be selected based on the specific vision condition of the eyes on both sides of the wearer, when the wearer with better left side view uses the AR display device, the wearing mode of outputting the projection light on the left side may be adopted, and when the wearer with better right side view uses the AR display device, the wearing mode of outputting the projection light on the right side may be adopted.

Of course, for the wearer with the left and right vision not having too great difference, when receiving the projection picture displayed in a monocular way, the wearing mode of the AR display device can be switched at any time, so that the projection picture can be watched by using the left eye and the right eye alternately, and the aim of relaxing the single eye in turn can be achieved.

Of course, the AR display device performing projection display according to the second display manner described above may be applied to AR swimming goggles as well, that is, only one side of the waveguide lens 5 is output with projection light at a time, and the eyes of the wearer receiving the projection light also change correspondingly with the switching of the wearing mode, so that the wearer does not need to distinguish the problem of the AR swimming goggles when wearing the AR swimming goggles.

The third display mode of the AR display device, that is, the light source module 4 is fixed to project the output projection light to one eye of the wearer even as the wearing mode of the AR display device is switched. The display device comprises two waveguide lenses 5 or the waveguide lenses 5 which are integrally formed with the lenses corresponding to the left eye and the right eye, two light source modules 4 are arranged, a projection picture formed by the output projection light rays is inverted up and down, and only one light source module 4 is started to work at a time.

The AR display device of the third display mode may be used in the case where the wearer's left and right eyes have different vision. However, unlike the AR display device of the second display mode, the AR display device of the third display mode may be used as a device for fixing a wearer. For example, for the second display mode, it may be used for AR display devices similar to those used by floating customers in a mall, i.e. the wearer is not fixed, and thus the preference for monocular projection display is not fixed. For the third display mode, the AR display device can be used for purchasing the AR display device for customers who use the AR display device or use the AR display device by specific personnel, that is, the wearer fixes the vision condition of the eyes on the left and right sides of the AR display device, that is, the vision condition of the eyes on the left and right sides of the AR display device is fixed, so that the eyes on only one fixed side of the AR display device are more suitable for receiving the watching projection light. Therefore, the problem that the projection mode is not suitable for a wearer due to the switching of the wearing mode of the AR display device is avoided.

In summary, the AR display device of the present utility model may be worn according to two different wearing modes, and in order to ensure that in each wearing mode, a wearer may receive a normal forward-displayed projection image, the corresponding light source module outputs projection light according to different projection modes for the two wearing modes, and the projection light respectively projected and output by the two projection modes finally forms a projection image that is upside down; in practical application, the AR display device only needs to select a projection picture which can be displayed forward and is currently watched by a wearer when being worn according to two wearing modes of up-down forward and reverse switching; therefore, in the AR display device similar to the only monocular display, a wearer can select different wearing modes according to the use habit of the wearer and different definition of left and right eye objects, and the requirement of normally watching a projection picture can be met. Therefore, the AR display device provided by the utility model adopts the light source modules with two different projection modes, so that the requirements of more diversification and individuation of users can be met.

Based on the above discussion, switching of different projection modes of the light source module 4 in the AR display device may be accomplished by a processor connected to the light source module 4. It is obvious that the processor needs to determine whether the wearing mode of the AR display device is switched if the processor triggers the switching of the projection mode of the light source module 4. To this end, in another alternative embodiment of the present utility model, the processor may further be connected with a wearing mode sensor provided inside the AR display device, monitoring the wearing mode of the AR display device. The wearing mode sensor can specifically adopt a three-dimensional acceleration sensor or other similar structural devices, so long as the current wearing mode of the AR display device can be monitored and determined.

When the wearing mode sensor monitors that the AR display device is worn according to the first wearing mode, a signal corresponding to the first wearing mode can be sent out to the processor, and the processor can trigger the light source module to output projection light according to the corresponding first projection mode. When the wearing mode sensor detects that the AR display device is worn according to the second wearing mode, the processor may send a signal corresponding to the second wearing mode to the processor, and the processor may trigger the light source module 4 to output projection light according to the corresponding second projection mode.

In another optional embodiment of the present utility model, a wireless communication module may be further configured on the processor, so that the processor may be in wireless communication connection with a mobile terminal such as a mobile phone, a tablet, or the like. At this time, the wearer can selectively and directly manually operate on the mobile terminal to send a wearing mode selection signal to the processor according to whether the currently observed projection picture is inverted or not, and the processor triggers the light source module 4 to output projection light according to the corresponding projection mode according to the received wearing mode selection signal.

The wearing mode switching button can also be directly arranged on the AR display device, and when the wearer wears the AR display device, if the current projection picture is an inverted projection picture, the wearing mode switching button is directly operated to send a switching signal to the processor, so that the processor triggers the light source module 4 to switch the projection mode.

The utility model also provides AR glasses comprising the AR display device.

As described above, for AR glasses, in practical application, different projection modes correspond to different wearing modes. In practical applications, AR glasses may face different wearers, and there may be different projection display requirements. When different wearers use the same AR glasses or the same wearer wants to change the projection mode, the wearing mode of the AR glasses is correspondingly required to be changed. However, the temple of AR glasses needs to have a definite bending direction in order to better hook the ear of the wearer. Thus, in order to enable easy wearing of the AR glasses by a wearer in both different wearing modes, in a further alternative embodiment of the present utility model, the AR glasses may further comprise: and the glasses leg can rotate at least 180 degrees, wherein the rotation center axis of the glasses leg is the axis of the glasses leg along the length direction.

Furthermore, in another alternative embodiment of the present utility model, the AR glasses may further include an adjustable nose bridge to correspond to the first wearing mode and the second wearing mode of the AR glasses.

When the AR glasses are worn according to the first wearing mode and the second wearing mode, respectively, the optimal setting positions of the nose bridge on the AR glasses are obviously, i.e. correspondingly different, and for this reason, the nose bridge in the present embodiment may be set as a nose bridge that is movably adjustable, so as to adapt to different wearing modes.

Embodiments of AR goggles may also be included in the present utility model, which may include an AR display device as described in any of the above.

As shown in fig. 1, fig. 1 is an embodiment of a monocular AR swimming goggle. The AR swimming goggles may include an eyecup 1, a nose bridge 2, a strap 3, a light source module 4, and a waveguide lens 5. The light source module 4 is arranged in any one of the left eye cover and the right eye cover, the AR swimming goggles comprise a waterproof shell, and the waterproof shell is further provided with a processor. The projection light outputted by the light source module 4 is conducted to eyes of a user after passing through the waveguide lens 5, and external light enters eyes of the user after passing through the waveguide lens 5.

When the left eye display state and the right eye display state need to be switched, a left instruction or a right instruction of the left eye display and the right eye display is issued through a mobile terminal (such as a mobile phone), the instruction reaches a processor, instruction information is sent to the light source module 4 by the processor, the light source module 4 outputs a projection image after being adjusted upside down, and meanwhile, the AR swimming goggles are taken off from the head of a user and worn reversely, so that the left eye display and the right eye display can be completed.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements is inherent to.
