Description

TECHNICAL FIELD

[0001] The present application relates to the field of head-mounted devices, in particular to a smart glasses. BACKGROUND

[0002] With the development of science and technology, smart glasses, as a kind of wearable device integrating fashion and high technology, have gradually been favored by consumers. Smart glasses not only can provide rich visual experience such as augmented reality and virtual reality, but also can realize functions such as calling, navigation, and health monitoring.

[0003] In the design of smart glasses, the difference in the demand of the user's forward tilt angle is one of the key factors that must be considered. The forward tilt angle, that is, the tilt angle of the lens relative to the vertical line, has a significant impact on the user's visual effect and wearing comfort. Different users may need different forward tilt angles to obtain the best viewing experience due to their different facial structures, head postures, and use scenarios.

[0004] The optical-mechanical module and the waveguide sheet are the core optical components of smart glasses, which are used together to realize image display function. In the related technology, the optical-mechanical module is usually fixed on the optical-mechanical support, and the optical-mechanical support is fixed with the waveguide sheet by point gluing, which means that the entire optical-mechanical support needs to be replaced when adjusting the forward tilt angle of the waveguide sheet to adapt to different use scenarios in production. Based on the requirements of the function of the optical-mechanical module and the mold forming, the structure of the optical-mechanical support is complex, so the replacement of the optical-mechanical support will increase the production cost. When replacing the waveguide sheet or the optical-mechanical shell, due to the firmness of the point gluing, it is difficult to disassemble the waveguide sheet or the optical-mechanical shell, which often requires the use of large external force or special tools. This not only consumes a lot of time and labor cost, but also is easy to cause damage to the optical-mechanical shell or the waveguide sheet during disassembly, thereby causing high cost loss, increasing the maintenance cost and difficulty of the product, and reducing the overall reliability and maintainability of the product.

[0005] In view of this, it is necessary to propose a new technical scheme to overcome the deficiencies in the prior art. CONTENT OF THE UTILITY MODEL

When a component is referred to as being "disposed on" another component, it can be directly disposed on the other component or there can be intervening components.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0041] As shown in Figure 1 and Figure 6 The present application provides an intelligent glasses 100, comprising a frame 10, a waveguide sheet 40, a light machine shell 20 and an optical support 30; the waveguide sheet 40 is fixedly installed on the frame 10; the light machine shell 20 is arranged in the frame 10 and is used for fixing a light machine module 22; the light machine shell 20 is installed on the waveguide sheet 40 through the optical support 30. Wherein, the waveguide sheet 40 has a light in-coupling area and a light out-coupling area, the light machine module 22 comprises a display device and a lens group, the light beam emitted by the display device is shaped by the lens group and then is incident on the light in-coupling area of the waveguide sheet 40, the light beam coupled into the waveguide sheet 40 through the light in-coupling area is transmitted in the waveguide in the form of total reflection, and then is coupled out to the human eye through the light out-coupling area.

[0042] Through the detachable connection between the optical support 30 and the light machine shell 20, the quick disassembly effect between the waveguide sheet 40 and the light machine shell 20 is realized, so as to facilitate the replacement of the waveguide sheet 40 or the light machine shell 20, and reduce the maintenance cost and difficulty. Moreover, the optical support 30 is simple in structure, and in the production process, the optical support 30 with a corresponding inclination angle can be replaced according to the use scene requirement, so as to avoid the replacement of the expensive and complex light machine shell 20 and reduce the production cost. In addition, for the intelligent glasses product without design requirement on the front inclination angle, the light machine shell 20 together with the light machine module in it can be directly used, and only the optical support 30 needs to be disassembled, without the need to redesign the light machine module and the light machine shell 20.

[0043] In the embodiment, as Figures 1 to 6As shown, the specific functions of the smart glasses 100 are not strictly limited, and can refer to the prior art, which will not be further elaborated here; for example, the smart glasses 100 integrates multiple functions such as displaying information, navigation, taking pictures, etc.

[0044] In the embodiment, as shown in Figures 1 to 2 and Figure 5 As shown, the number of waveguide sheets 40 can be one or two; each waveguide sheet 40 is mounted to the frame 10; the waveguide sheet 40 is a key component in the smart glasses 100, responsible for guiding image light to the user's eyes.

[0045] In the embodiment, as shown in Figures 1 to 2 As shown, the frame 10 is the main part of the smart glasses 100, used to support and fix the optical machine shell 20 and the waveguide sheet 40 and other structures. The frame 10 has a mounting cavity 11, and the optical machine shell 20 is located in the mounting cavity 11; the optical machine shell 20 is directly embedded and mounted to the inside of the frame 10 without leaking, making the structure of the smart glasses 100 more compact and the appearance more beautiful. In other embodiments, to further ensure the mounting firmness of the optical machine shell 20, the optical machine shell 20 can be bonded in the mounting cavity 11.

[0046] In the embodiment, as shown in Figures 1 to 2 As shown, the smart glasses 100 also include the temples 50; the number of temples 50 is two, and both temples 50 are mounted to the frame 10. The temples 50 can be connected to the frame 10 by screws, buckles or shafts, etc. Among them, the temple 50 is in the form of a rod, and the temple 50 has a length direction in space.

[0047] In the embodiment, as shown in Figures 2 to 5 As shown, the optical support 30 is clamped with the optical machine shell 20, which makes the connection between the optical support 30 and the optical machine shell 20 more firm and reliable, and also facilitates the user to disassemble and replace. Specifically, one of the optical support 30 and the optical machine shell 20 is provided with a clamping protrusion 21, and the other is provided with a clamping groove 31 clamped with the clamping protrusion 21. For example, the optical support 30 is provided with a clamping groove 31, and the optical machine shell 20 is provided with a clamping protrusion 21.

[0048] In the embodiment, as shown in Figures 2 to 6As shown, the light machine shell 20 has a light outlet 23, the optical support 30 has a light passage 36 communicating with the light outlet 23, and at least part of the light machine shell 20 extends into the light passage 36, so that the optical support 30 and the light machine shell 20 are stably connected; in addition, it can also prevent unnecessary displacement or shaking of the optical support 30 and the light machine shell 20 during use, further ensuring the optical performance and stability of the overall structure of the smart glasses 100. When assembling, the light machine shell 20 is aligned with the light passage 36 of the optical support 30, and then the light machine shell 20 or the optical support 30 is pushed so that the light machine shell 20 moves along the light passage 36 until the clamping protrusion 21 is clamped with the clamping groove 31, thereby completing the connection of the two, which is simple and fast, and does not require complex tools and professional skills. The light beam emitted by the display device in the light machine module is shaped by the lens group, and then enters the light coupling-in area of the waveguide sheet 40 through the light outlet 23 and the light passage 36.

[0049] In this embodiment, as shown in the figure, Figures 2 to 3 The optical support 30 has an adhesive surface 33, and the adhesive surface 33 is fixed with the waveguide sheet 40 by glue dispensing. The adhesive surface 33 is attached to the waveguide sheet 40 to ensure the position stability of the waveguide sheet 40 during installation and prevent displacement during assembly or use. The optical support 30 is located between the waveguide sheet 40 and the light machine shell 20; the adhesive surface 33 and the connecting groove 32 are arranged on the two sides of the optical support 30, respectively. The optical support 30 is provided with a glue dispensing port 37, which facilitates the assembly of the waveguide sheet 40 on the adhesive surface 33 to achieve preliminary positioning, and then the adhesive surface 33 and the waveguide sheet 40 are glued to achieve further fixation.

[0050] In this embodiment, as shown in the figure, Figures 2 to 3 The optical support 30 also has a glue overflow surface 34, and the glue overflow surface 34 is arranged in a gap with the waveguide sheet 40, so as to accommodate the excess glue during the glue dispensing assembly of the waveguide sheet 40 and the adhesive surface 33, prevent the glue from overflowing to unwanted places, and affect the assembly and performance of the smart glasses 100. The glue overflow surface 34 is used to further fix the waveguide sheet 40 through the excess glue overflowed therebetween, which not only enhances the connection strength between the waveguide sheet 40 and the optical support 30, but also makes the fixing process more simple and efficient. Through the cooperation of the adhesive surface 33 and the glue overflow surface 34, the waveguide sheet 40 is stably installed, and good display effect and use experience are ensured.

[0051] In this embodiment, as shown in the figure, Figures 2 to 6 The adhesive surface 33 is arranged obliquely, so that the forward inclination angle of the smart glasses 100 is 2-10 degrees; by adjusting the forward inclination angle of the smart glasses 100, the user can wear the smart glasses 100 more comfortably, and the visual fatigue and discomfort caused by too large or too small forward inclination angle can be reduced.

[0052] In this embodiment, as Figures 2 to 6 As shown, the angle between the adhesive surface 33 and the vertical direction is 2 to 10 degrees, or the angle between the adhesive surface 33 and the length direction of the temple 50 is 80 to 88 degrees. This angle range allows the smart glasses 100 to have a forward tilt angle of 2 to 10 degrees, thus meeting the needs of different users for wearing comfort and visual experience. For example, Figure 2 As shown, the angle between the adhesive surface 33 and the vertical direction is a, and the angle between the adhesive surface 33 and the length direction of the temple 50 is b.

[0053] Preferably, the angle between the adhesive surface 33 and the vertical direction is 2 to 8 degrees, or the angle between the adhesive surface 33 and the extending direction of the temple root 51 is 82 to 88 degrees, so that the forward tilt angle of the smart glasses 100 is 2 to 8 degrees. This angle range has been proven to provide users with the best visual effect and wearing comfort in most usage scenarios. More preferably, the angle between the adhesive surface 33 and the vertical direction is 2 to 6 degrees, or the angle between the adhesive surface 33 and the extending direction of the temple root 51 is 84 to 88 degrees, so that the forward tilt angle of the smart glasses 100 is 2 to 6 degrees. Specifically, the angle between the adhesive surface 33 and the vertical direction can be 2°, 3°, 4°, 5°, 6°, or any range of two values.

[0054] In this embodiment, as Figures 2 to 6 As shown, the waveguide 40 has a connecting portion 41, which is fixed to the adhesive surface 33. The optical support 30 includes a positioning flange 35 located on the outer periphery of the connecting portion 41 to position the waveguide 40 relative to the optical support 30. The optical coupling entry area of ​​the waveguide 40 is located on the connecting portion 41, corresponding to the light-transmitting port 36 on the optical support 30. During assembly, the positioning flange 35 accurately positions the waveguide 40 and the optical support 30, ensuring the waveguide 40 is correctly installed in the predetermined position. Then, the connecting portion 41 is tightly fitted and fixed to the adhesive surface 33, and the connection is secured by dispensing adhesive to ensure a strong connection. The dispensing port 37 is located on the positioning flange 35. In some embodiments, the light outlet 23 of the optical engine housing 20 is generally disposed on one side of the waveguide 40. In order for the waveguide 40 to receive the light beam emitted by the display device in the optical engine module, the waveguide 40 may extend a connecting portion 41 to receive the light beam from the display device through the connecting portion 41.

[0055] In this embodiment, as Figures 2 to 5As shown, the connecting portion 41 is located at the outer edge of the waveguide sheet 40 and is outwardly protruding. The height of the positioning flange 35 is higher than that of the adhesive surface 33 and is substantially flush with the side of the waveguide sheet 40 opposite to the adhesive surface 33.

[0056] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they shall be considered within the scope of the present disclosure. When the technical features in different embodiments are embodied in the same figure, it can be considered that the figure also discloses the combination of the embodiments involved.

[0057] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent application scope. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application.
