Description

Technical Field

[0001] The present application relates to the field of consumer electronic products, and in particular to an optical machine and a wearable device. Background Art

[0002] At present, existing wearable devices, such as optical machines, can be attached to the user's glasses. In this case, the glasses serve as the carrier of the optical machine, and the optical machine projects the image in front of the user's eyes through an optical module. The user can watch the image of the optical module and can also take it off when the wearable device is not needed.

[0003] However, the existing optical machine, when installed on glasses, is usually only installed on one side of the glasses (for example, only on the right ear side). In this way, when the user wears the glasses for a long time, the right ear side of the glasses will be heavier, so the force borne by the right ear is greater than that of the left ear, and the left and right are unbalanced, which will make the user feel uncomfortable when wearing the glasses and is not conducive to long-term wear. Summary of the invention

[0004] The purpose of this application is to provide an optical machine and a wearable device to improve the above-mentioned technical problems and reduce the discomfort caused by left-right imbalance when the user uses it.

[0005] In a first aspect, an embodiment of the present application provides an optical machine suitable for being installed on glasses, wherein the glasses include a frame and a glasses frame, wherein the frame is connected to the glasses frame, and an end of the frame away from the glasses frame is bent to form an ear hook, and the optical machine includes a display part and a mounting part, wherein the display part has a display interface, and the mounting part is connected to the display part, and the mounting part has a bottom surface, and the bottom surface is suitable for being fitted and connected with the glasses frame, and when the mounting part is connected to the glasses frame, the mounting part is located on a side of the bottom surface away from the ear hook.

[0006] In a second aspect, an embodiment of the present application further provides a wearable device, comprising the above-mentioned optical machine and glasses, wherein the glasses comprise a frame and a glasses frame.

[0007] The optical machine and wearable device provided in the embodiments of the present application can be fitted and connected to the frame of the glasses through the mounting portion when the optical machine is installed, and during the installation process, the bottom surface of the mounting portion is connected to the frame so that the center of gravity line of the mounting portion passes through the bottom surface, that is, the center of gravity of the mounting portion is located above the frame, and the weight of the entire optical machine can be borne more evenly by the frame, so that for the frame, the pressure on the user's ears is more even, thereby reducing the user's discomfort during wearing.

[0008] The backlight module and display device using the backlight plate can reduce manufacturing costs, ensure the assembly effect of the optical module, and avoid light leakage.

[0009] These and other aspects of the present application will become more clearly understood in the description of the following embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] Virtual Reality (VR) is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment and immerse users in it. Virtual reality technology uses real-life data, electronic signals generated by computer technology, and combines them with various output devices to transform them into phenomena that people can feel. These phenomena can be real objects in reality or substances that are invisible to our naked eyes, which are expressed through three-dimensional models.

[0021] Augmented Reality (AR) technology is a technology that cleverly integrates virtual information with the real world, superimposing virtual display content on real scenes. It uses computer technology to generate virtual information, such as visual images, sounds, etc., and then applies the virtual information to the real world. Virtual reality technology not only displays real-world information, but also can display virtual information at the same time. The two types of information complement and overlap each other.

[0022] Mixed Reality (MR) introduces real-world scene information into a virtual environment, building an interactive feedback information loop between the virtual world, the real world, and the user to enhance the realism of the user experience.

[0023] Some existing wearable devices can realize VR, AR or MR display. Such wearable devices include an optical machine, which has a display interface for display. For people with myopia, existing optical machines are mostly worn by attaching them to glasses worn by users. Usually, the optical machine is installed on one of the temples of the glasses frame and is suspended on the outside of the temple, that is, on the side of the temple away from the user's face. Taking the installation of the optical machine on the right ear as an example, this installation method has the following disadvantages: Since the optical machine has a certain weight and is usually heavier than glasses, after the optical machine is installed, most of the weight is borne on the temples and then on the user's ears, which increases the load on the right ear. At the same time, since the optical engine is installed on the outside of the temple, the load-bearing outside of the temple is greater than that of the inside, and the temple generates an outward tilting moment. The tilting moment acts on the user's right ear, causing the entire glasses to tend to tilt toward the right ear. In this way, the load-bearing on the right ear will be further significantly greater than that on the left ear, aggravating the imbalance between the left and right ears. When the user wears the glasses for a long time, the right ear will feel uncomfortable, which is not conducive to the long-term use of the product and limits the application of optical engines and wearable devices.

[0024] Based on this, the inventor of the present application proposes an optical machine and a wearable device according to each embodiment of the present application, in order to improve the above-mentioned defects. The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0025] See also Figure 1 This embodiment provides a wearable device 10, including an optical machine 30 and glasses 20, wherein the optical machine 30 can be detachably assembled on the glasses 20 to achieve a display effect of virtual reality, augmented reality, or mixed reality.

[0026] Specifically, the glasses 20 include a frame 21 and a glasses frame 22, wherein the glasses frame 22 is used to install the lenses 23, and the glasses frame 21 is connected to the frames 22 and is used for the user to wear. It should be noted that the frames 22 and the frames 21 can be made of various materials such as metal, plastic, ceramic, etc., which are not limited here. The frame 22 can include two independent frame structures for installing two lenses 23 separated from each other, and corresponding to the left eye and the right eye of the user respectively. It should be noted that the lenses 23 can be myopic lenses 23, flat lenses 23, filter lenses 23, etc., which are not limited here. In some other embodiments, the lenses 23 may not be set in the frame 22, and the glasses 20 can only be used as a decorative tool for the user.

[0027] In some embodiments, the frame 21 may include two frame legs, which are respectively disposed on opposite sides of the frame 22 and connected to the frame 22. The two frame legs are arranged in a substantially symmetrical structure, and in some embodiments, the frame legs may be connected to the frame 22 in a hinged manner to facilitate storage of the frame legs. Of course, in some other embodiments, the frame legs may also be fixedly connected to the frame 22.

[0028] In this embodiment, the structures of the two frame legs are the same. Figure 1 and Figure 2 , taking one of the frame legs as an example, each frame leg includes a first connecting segment 211 and a second connecting segment 212, one end of the first connecting segment 211 is fixedly connected to the frame 22, and the other end is hinged to the second connecting segment 212, and the end of the second connecting segment 212 away from the first connecting segment 211 is bent to form an ear hook 26, that is, the end of the frame 21 away from the frame 22 forms an ear hook 26, and the ear hook 26 is used to hang on the ear of the user when in use. Among them, the connection between the first connecting segment 211 and the frame 22 can be smoothly transitioned toward the lens 23 to increase the aesthetics.

[0029] The first connecting section 211 includes a first surface 2111, a second surface 2112 and an outer side surface 2113 facing each other. The first surface 2111 is located at the top of the first connecting section 211, and the second surface 2112 is located at the bottom of the first connecting section 211, wherein the bottom refers to the side surface of the first connecting section 211 close to the ear hook, and the top refers to the side surface of the first connecting section 211 close to the ear hook. When the user wears the glasses 20, the first surface 2111 is located above the second surface 2112, that is, the second surface 2112 is closer to the ground than the first surface 2111. It should be noted that the first surface 2111 and the second surface 2112 can be a plane or a curved surface of any shape, which is not limited here. At the same time, the first connecting section 211 also has a first side 24 and a second side 25 opposite to the first side 24. The first side 24 is located on the side of the first connecting section 211 close to the user's face, that is, close to the other frame leg, and the second side 25 is located on the side of the first connecting section 211 away from the user's face. The outer side surface 2113 is connected between the first surface 2111 and the second surface 2112, and is connected to the first surface 2111 and the second surface 2112 at an angle of approximately 90°. The outer side surface 2113 is located on the outside of the frame leg. When the user wears the glasses 20, the outer side surface 2113 is exposed as a partial appearance surface of the frame leg.

[0030] In some embodiments, the first surface 2111 can be set as a plane to better fit the optical machine 30. In this embodiment, the portion of the first surface 2111 close to the frame 22 is set as an arc surface, and the portion of the first surface 2111 away from the frame 22 is set as a plane. This setting method can increase the design aesthetics of the frame 21.

[0031] Please also read Figure 1 and Figure 3 The optical machine 30 includes a display unit 50 and a mounting unit 40. The display unit 50 has a display interface 51, and the display interface 51 is used for display and / or human-computer interaction. The mounting unit 40 is used for assembly and connection with the glasses 20. During installation and use, the display interface 51 of the display unit 50 can be directly opposite to the lens 23 of the glasses 20 or directly opposite to the frame 22, so that the display interface 51 is located in front of the user's eyes for easy viewing by the user. Among them, the display unit 50 can include only one display interface 51. In some embodiments, the display unit 50 can also have two display interfaces 51, and the two display interfaces 51 are respectively arranged corresponding to the two lenses 23. And when there are two display interfaces 51, when displaying, the two display interfaces 51 can display the same content or different content.

[0032] It is understandable that the optical engine 30 may further include a driving module, which may be disposed inside the mounting portion 40 and used to drive the display portion 50 to display. Figure 4 A schematic diagram of the structure of a driving module is shown. The driving module may include an optical fiber driver 140 and an optical fiber scanning device 110. The optical fiber scanning device 110 includes a housing 111, an optical fiber 113, and a driving device 112. The housing 111 may be a shell of the mounting portion 40. The optical fiber 113 is disposed in the housing 111 and is disposed approximately along a straight line. The optical fiber 113 has a scanning end 1131 and a receiving end 1132. The scanning end 1131 is used to scan and face the display interface 51 of the display portion 50 to form an image on the display interface 51. The receiving end 1132 is used to receive optical signals. The scanning end 1131 is a cantilever structure that can swing freely in space. The receiving end 1132 can be configured as a fixed structure to stably receive optical signals.

[0033] The driving device 112 is disposed on the housing 111 and is used to drive the scanning end 1131 to scan. Specifically, in this embodiment, the driving device 112 is a piezoelectric element, which may be a piezoelectric ceramic, etc. The piezoelectric element may be one, two or more. As an embodiment, there may be two piezoelectric elements, and the two piezoelectric elements are arranged along a first direction and a second direction perpendicular to each other, and are used to provide a driving force along the first direction and a driving force along the second direction for the cantilever of the optical fiber 113, so that the scanning end 1131 of the optical fiber 113 can move along any trajectory in a plane and scan according to a predetermined trajectory. In some other embodiments, the driving device 112 may also be other structures, such as a micro motor, etc.

[0034] The optical fiber driver 140 is used to receive a signal source and transmit an optical signal to a receiving end 1132. As an example, the optical fiber driver 140 includes a processor 141, a light source modulation module 142, a scanning drive circuit 143, and a signal transmitting device 144, wherein the light source modulation module 142 is electrically connected to the signal transmitting device 144, the processor 141 is electrically connected to the light source modulation module 142 and the scanning drive circuit 143, the processor 141 controls the light source modulation module 142, the light source modulation module 142 receives the signal source, and modulates the optical signal according to the signal source, and controls the signal transmitting device 144 to transmit the corresponding optical signal. The signal transmitting device 144 can be an emitting mixed light or a monochromatic light, which is not limited here. The scanning drive circuit 143 is electrically connected to the driving device 112 and is used to control the driving device 112 to execute a predetermined driving strategy. The processor 141 may include one or more processing cores. The processor 141 uses various interfaces and lines to connect the various parts of the entire optical machine 30, and executes various functions and processes data of the optical machine 30 module 100 by running or executing stored instructions, programs, code sets or instruction sets, and calling stored data. Optionally, the processor 141 can be implemented in at least one hardware form of digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA). The processor 141 can integrate one or a combination of a central processing unit 141 (CPU), a graphics processing unit 141 (GPU), and a modem. Among them, the CPU mainly processes the operating system, user interface, and application programs; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications. It can be understood that the above-mentioned modem may not be integrated into the processor 141, but may be implemented separately through a communication chip.

[0035] As an example, the signal emitting device 144 includes a laser emitting device 1441 and a beam combining device 1442. The laser emitting device 1441 excites the emitted laser beam and can control the signal intensity, chromaticity and other parameters of the laser beam. The laser emitting device 1441 can be composed of multiple monochromatic laser emitters. For example, the laser emitting device 1441 can include a red light emitter, a green light emitter and a blue light emitter. Multiple monochromatic laser emitters are combined by the beam combining device 1442, so that the monochromatic light emitted by multiple monochromatic laser emitters is combined and emitted, that is, the light beam at the time of emission is mixed light and can be modulated into any color. In some other embodiments, the laser emitting device 1441 can also be a monochromatic laser emitter of other colors, such as a yellow light emitter, a magenta light emitter, etc., which are not limited here. In addition, the signal emitting device 144 can also be provided without the beam combining device 1442, and directly emits multiple monochromatic light beams to the optical fiber 113 through the connecting line 150, so that they are imaged on the display interface 51 after being scanned by the optical fiber 113. It is understandable that in some other implementations, other driving modes may be used to drive the display, which is not limited here.

[0036] like Figure 1 As shown, the mounting portion 40 is mounted on one of the frame legs of the frame 21, and the entire optical engine 30 is fixed on the glasses 20. It can be understood that in some embodiments, the mounting portion 40 can be detachably provided on the frame 21, so that when the optical engine 30 is not needed, the optical engine 30 can be removed more quickly to reduce the weight of the glasses 20.

[0037] For details, please continue to refer to Figure 1 and Figure 4 The mounting portion 40 is connected to the display portion 50 at an angle of approximately 90 degrees, and is approximately adapted to the connection angle between the frame 21 and the frame 22, so that when the mounting portion 40 is mounted on the frame leg, the display portion 50 is located just in front of the lens 23. The mounting portion 40 has a bottom surface 41, which is suitable for being fitted and connected to the frame 21. When assembled, the bottom surface 41 is fitted and arranged with the top of the frame 21. When the mounting portion 40 is connected to the frame 21, the mounting portion 40 is located on the side of the bottom surface 41 away from the ear hook 26, that is, the mounting portion 40 is located above the bottom surface 41 or the frame 21.

[0038] At the same time, when the mounting portion 40 is connected to the frame 21, the center of gravity of the mounting portion 40 passes through the bottom surface 41, that is, the mounting portion 40 is located above the frame 21 as a whole, and the overall weight of the optical machine 30 is located above the frame 21. The center of gravity refers to the line between the center of gravity of the mounting portion 40 and the center of the earth. It should be noted that the bottom surface 41 can be configured to match the top of the frame 21 to increase the connection stability between the mounting portion 40 and the frame 21.

[0039] The advantage of this arrangement is that, since the mounting portion 40 is located above the frame 21, that is, the weight of the entire optical engine 30 is placed above the frame 21, the pressure from the optical engine 30 on the first side 24 (the side close to the user's face) and the second side 25 (the side away from the user's face) of the frame leg is more balanced, so a large tipping moment is not generated, and the discomfort of the user's ears is reduced. Furthermore, the center of gravity of the mounting portion 40 can pass through the middle of the bottom surface 41, so that the pressure from the optical engine 30 on the first side 24 and the second side 25 of the frame leg is more balanced, further reducing the tipping moment generated by the optical engine 30.

[0040] In one embodiment, after the mounting portion 40 is connected to the display portion 50, the center of gravity of the entire optical machine 30 is located on the side of the mounting portion 40 close to the display portion 50. After the optical machine 30 is installed on the glasses 20, the center of gravity of the optical machine 30 will be close to the first side 24 of the frame leg. Therefore, the center of gravity line of the mounting portion 40 can be set close to the first side 24, which can further reduce the tipping moment and reduce discomfort.

[0041] In this embodiment, the bottom surface 41 includes a contact area 410 for contacting the frame 21. When the optical machine 30 is installed on the frame 21, the contact area 410 contacts the first surface 2111 of the frame 21. The contact area 410 is provided with a magnetic member 42, which is magnetically connected to the frame 21 through the magnetic member 42, thereby fixing the mounting portion 40 and the frame 21 relatively. It can be understood that the frame 21 can be a metal frame 21 at this time, so that the mounting portion 40 can be directly adsorbed to the frame 21 through the magnetic member 42. In one embodiment, see 2, a magnetic connector 62 can be provided in the frame 21, and the magnetic member 42 is connected by adsorption with the magnetic connector 62, wherein the magnetic connector 62 can be provided on the first surface 2111, and is provided corresponding to the contact area 410 of the bottom surface 41. It can be understood that at least one of the magnetic member 42 and the magnetic connector 62 is a magnet, and the other can be a magnet or a material that can be magnetically adsorbed to a magnet, such as metal iron. The above-mentioned magnetic attraction refers to the mutual attraction of the ends of the magnetic member 42 and the magnetic connecting member 62 with opposite magnetic poles.

[0042] Usually, when the frame 21 of the glasses 20 is set, the portion of the first connecting section 211 connected to the frame 22 is designed with a curved surface to increase the streamlined beauty of the glasses 20. In order to more firmly fix the optical engine 30 and prevent the optical engine 30 from falling off the glasses 20 during movement, shaking or even collision. Figure 3As shown, the contact area 410 includes a first contact surface 411 and a second contact surface 412, the magnetic member 42 is arranged on the first contact surface 411, and the first contact surface 411 is substantially a plane, the second contact surface 412 is a curved surface, the second contact surface 412 is connected to the first contact surface 411 and smoothly transitions, and the second contact surface 412 protrudes from the first contact surface 411. Correspondingly, the portion of the first surface 2111 close to the frame 22 is arranged as an arc-shaped curved surface, and the portion of the first surface 2111 away from the frame 22 is arranged as a plane, and this arrangement can increase the design aesthetics of the frame 21. During installation, the first contact surface 411 is in contact with the portion of the first surface 2111 away from the frame 22, and the second contact surface 412 is in contact with the portion of the first surface 2111 close to the frame 22.

[0043] For ease of explanation, Figure 3 In the coordinate system shown, the second contact surface 412 is located in the Y+ direction of the first contact surface 411. Since the second contact surface 412 protrudes relative to the first contact surface 411, the second contact surface 412 can play a role in fixing the mounting portion 40 along the Y-direction, preventing the mounting portion 40 from sliding along the Y-direction. In addition, this design can also increase the contact area between the first contact surface 411 and the second contact surface 412 and the first surface 2111, thereby improving stability. At the same time, since the second contact surface 412 protrudes from the first contact surface 411, it can play a role in positioning the mounting portion 40 during the installation process, so that the positions of the magnetic member 42 disposed on the first contact surface 411 and the magnetic connector 62 disposed on the first surface 2111 can just correspond, thereby achieving precise assembly. Wherein XYZ is a spatial coordinate system.

[0044] The above can only realize the Y-axis positioning of the mounting portion 40. In order to further improve the connection stability of the optical machine 30 during the installation process. Figure 3 The optical machine 30 may further include a fixing portion 43, which is disposed at the edges of the first contact surface 411 and the second contact surface 412 and protrudes from the bottom surface 41. When the first contact surface 411 and the second contact surface 412 are mounted on the first surface 2111, the fixing portion 43 will be fixed to the side of the frame leg, so that the degree of freedom of the mounting portion 40 along the X direction is limited. It can be understood that the fixing portion 43 can be only disposed on the first side 24 or the second side 25 of the frame leg, in which case the degree of freedom of movement in the X+ or X- direction can be limited. It can also be disposed on both the first side 24 and the second side 25 of the frame leg, in which case the degree of freedom of movement in both the X+ and X- directions can be limited.

[0045] Just as an example, in this embodiment, Figure 5As shown, the fixing portion 43 includes a first fixing portion 431 and a second fixing portion 432. The first fixing portion 431 is arranged at the edge of the first contact surface 411, and the second fixing portion 432 is arranged at the edge of the second contact surface 412 and is located on the same side of the contact area 410 as the first fixing portion 431. The first fixing portion 431 is connected to the second fixing portion 432. The first fixing portion 431 is configured to be adapted to the edge of the first contact surface 411, and the second fixing portion 432 is configured to be adapted to the edge of the second contact surface 412. Since the first contact surface 411 is approximately a plane and the second contact surface 412 is a curved surface, the first fixing portion 431 and the second fixing portion 432 are respectively configured to match the first contact surface 411 and the second contact surface 412, so that the length of the fixing portion 43 protruding from the bottom surface 41 can be kept approximately the same. During the installation process, the fixing portion 43 and the side surface of the frame leg can have a higher fitting area, thereby improving the limiting effect on the X direction.

[0046] It should be noted that, in the present embodiment, the fixing portion 43 is only arranged on one side of the contact area 410, and the fixing portion 43 is located on the first side 24 of the frame leg, that is, on the side of the frame leg close to the user's face. In this arrangement, when the user is installing the optical machine 30, he only needs to hold the optical machine 30 and install the mounting portion 40 of the optical machine 30 on the frame leg from above the frame leg. When the fixing portion 43 abuts against the frame leg, it indicates that the installation is in place. The user's head can clamp and fix the mounting portion 40 with the frame leg, thereby achieving the X-direction positioning and fixation of the mounting portion 40. Therefore, the above embodiment can be assembled more conveniently and at the same time can reduce the manufacturing cost of the fixing portion 43.

[0047] Please continue reading Figure 5 and Figure 6 The connection between the display part 50 and the mounting part 40 has a transition surface 70, which is arranged close to the display interface 51 and located on the inner side of the mounting part 40. The transition surface 70 may be an arc-shaped curved surface or other curved surfaces. This design method can improve the aesthetic appearance of the optical machine 30. At the same time, during assembly, the transition surface 70 can be fitted to the connection between the frame leg and the frame 22, and the transition surface 70 is fitted to the surface of the frame 22 away from the user's eyes, so that the freedom of movement of the mounting part 40 along the Y-direction is limited, and the mounting part 40 is further stabilized. Prevent the mounting part 40 from falling off during the user's movement, shaking, etc.

[0048] The wearable device 10 provided in this embodiment is installed with the optical engine 30 above the glasses 20 during assembly, so that the weight of the optical engine 30 can be more evenly loaded on the legs of the glasses frame without generating a large tipping moment. During wearing, the user will not experience a strong sense of discomfort in the ears, which is conducive to long-term use by the user.

[0049] For consumers, when the optical machine 30 is not in use, the glasses 20 are usually used as a daily necessity for myopic people. Currently, the glasses 20 are mostly made of lightweight materials such as plastics and resins, which do not have the ability to be adsorbed by the magnetic member 42. Therefore, there are inconveniences in the process of installing the optical machine 30, which is not conducive to the use and promotion of the optical machine 30. Based on this, the present embodiment also provides another structure of the optical machine 30. In addition to the above structure, the optical machine 30 has a Figure 7 As shown, it also includes a fastening piece 60, which is separately arranged from the mounting portion 40 and the display portion 50. The fastening piece 60 has a top surface 61 suitable for fitting with the frame 21. Specifically, the top surface 61 is used to fit with the second surface 2112 of the frame leg. The top surface 61 is provided with a magnetic connecting piece 62 that cooperates with the magnetic piece 42 provided on the bottom surface 41. When in use, the mounting portion 40 of the optical engine 30 is mounted on the first surface 2111 of the frame leg, and the buckle 60 is moved from the bottom of the frame leg close to the second surface 2112, and the top surface 61 is made to fit with the second surface 2112. At this time, the magnetic member 42 and the magnetic connecting member 62 generate a magnetic force of attraction to each other. Since the frame legs are usually small in size, generally less than 0.5 cm, the frame legs will not affect the magnetic force between the magnetic member 42 and the magnetic connecting member 62 too much, and the buckle 60 can still be stably connected to the mounting portion 40 by magnetic connection. At this time, the frame leg is clamped between the bottom surface 41 of the mounting portion 40 and the top surface 61 of the buckle 60, thereby fixing the mounting portion 40. When it is necessary to remove it, the buckle 60 is removed, and then the optical engine 30 is removed.

[0050] As a method, the top surface 61 can be configured as an arc-shaped surface suitable for cooperating with the frame leg to increase the contact area with the frame leg and the stability of the buckle 60 connecting the frame leg.

[0051] This setting has the following advantages:

[0052] (1) Wide applicability. The optical machine 30 can be installed and used in conjunction with any existing glasses 20. Users do not need to replace the existing glasses 20 or install magnetic parts 42 on the frames 21. This can greatly improve the applicability of the optical machine 30, especially for consumers who use glasses 20 with plastic frames 21.

[0053] (2) Improving installation stability. Since the bottom surface 41 of the mounting portion 40 and the top surface 61 of the fastener 60 are arranged relative to each other, the magnetic adsorption force generated by the two acts on the frame legs at the same time. Both the bottom surface 41 and the top surface 61 generate friction with the frame legs, so that the mounting portion 40 will not deflect toward the side, thereby further reducing the tipping moment and reducing the user's discomfort.

[0054] In another embodiment, the mounting portion 40 may also be connected to the frame leg without magnetic adsorption, such as Figure 8 As shown, the mounting portion 40 is provided with a first buckle 44 and a second buckle 45, which are respectively located on both sides of the bottom surface 41, and are respectively located on the first side 24 and the second side 25 of the frame leg. A slot 46 for embedding the frame 21 is formed between the first buckle 44 and the second buckle 45, and one end of the slot 46 is open. At this time, the bottom surface 41 is located inside the slot 46. When the optical machine 30 needs to be installed on the frame 21, the mounting portion 40 is pressed toward the frame 21, so that the frame leg is embedded in the slot 46, and the bottom surface 41 is in contact with the first surface 2111 of the frame leg, so that the installation can be achieved. The frame leg can be fixed with the first buckle 44 and the second buckle 45 by interference fit. The advantage of this arrangement is that there is no need to set up the magnetic member 42 and the magnetic connector 62, etc., which reduces the weight of the entire wearable device 10. At the same time, the first buckle 44 and the second buckle 45 can limit the mounting portion 40 in both the X- and X+ directions at the same time, and the stability is better.

[0055] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
