Detailed Embodiments

[0024] The following describes in detail the embodiments of the present application. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0025] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0026] Please refer to Figure 1 , an embodiment of the present application provides a head-mounted device 500. Through the cooperation of the computing system and the optical system, after the user wears the head-mounted device 500, the head-mounted device 500 can send optical signals to the user's eyes, so as to achieve different effects such as virtual reality (VR), augmented reality (AR), and mixed reality (MR).

[0027] Please refer to Figure 1 , the head-mounted device 500 of the embodiment of the present application includes a main body 200 and temple arms 100, and the temple arms 100 are connected to the main body 200.

[0028] The main body 200 can be used to be worn in front of the user's eyes, and the temple arms 100 can be used to be worn on the user's ears, so that the head-mounted device 500 can be stably worn on the user's head. The temple arms 100 can be rotatably connected to the main body 200. For example, the temple arms 100 and the main body 200 can be penetrated by a rotating shaft, so that the temple arms 100 are rotatably connected to the main body 200.

[0029] Since the head-mounted device 500 is suitable for being worn on the user's head, therefore, how to make the head-mounted device 500 more miniaturized becomes the key to the design of the head-mounted device 500.

[0030] Please refer to Figure 2 and Figure 3 , the temple arms 100 of the embodiment of the present application include a protective shell 10 and a flexible circuit board 20, and the flexible circuit board 20 is arranged in the protective shell 10. The flexible circuit board 20 spirally winds and extends along the length direction of the protective shell 10.

[0031] In the temple 100 of the embodiment of the present application, the flexible circuit board 20 spirally winds and extends along the length direction of the protective shell 10, so that the lateral dimension formed by the flexible circuit board 20 is relatively small. Thus, when the flexible circuit board 20 is normally powered or transmits signals, the overall lateral dimension of the temple 100 is relatively small, which is beneficial to the miniaturized design of the head-mounted device 500.

[0032] It should be noted that the lateral dimension of the temple 100 refers to the diameter of the circumscribed circle of the outer contour of the cross-section of the temple 100 intercepted by a plane perpendicular to the length direction of the temple 100. For example, Figure 3 the D1 marked in is the lateral dimension of the temple 100. Similarly, the lateral dimension formed by the flexible circuit board 20 refers to the diameter of the circumscribed circle of the outer contour of the cross-section of the flexible circuit board 20 intercepted by a plane perpendicular to the length direction of the temple 100. For example, Figure 3 the D2 marked in is the lateral dimension formed by the flexible circuit board 20.

[0033] Specifically, the protective shell 10 can be strip-shaped. The protective shell 10 being strip-shaped means that the dimension of the protective shell 10 in one direction is much larger than the dimensions in the other two directions. For example, the dimension of the protective shell 10 in the X direction is more than 3 times the dimensions in the Y direction and the Z direction. The outer contour of the protective shell 10 can be linear or curved.

[0034] The protective shell 10 is the exterior part of the temple 100 and often comes into contact with external objects. Therefore, in order to improve the wear resistance of the protective shell 10, the protective shell 10 can be made of a relatively wear-resistant material. For example, the material of the protective shell 10 is silicone. Additionally, since the protective shell 10 comes into contact with the user's head skin, in order to increase the user's comfort, the protective shell 10 can be made of a relatively soft material.

[0035] As Figure 1 and Figure 2 shown, a bending portion 11 can be formed at one end of the protective shell 10 in the length direction. When the user wears the head-mounted device 500, the bending portion 11 can be placed on the user's ear, so that the head-mounted device 500 is not likely to slip off.

[0036] The flexible circuit board 20 (Flexible Printed Circuit, FPC) is a highly reliable and extremely flexible printed circuit board made with polyimide or polyester film as the base material. The flexible circuit board 20 has characteristics such as high wiring density, light weight, thin thickness, and good bendability.

[0037] Therefore, in this application, the flexible circuit board 20 is used as a signal transmission component, which can form multiple independent channels to achieve the versatility of signal transmission. For example, one channel is used to transmit communication signals, and another channel is used to transmit electrical energy.

[0038] In addition, the flexible circuit board 20 can be bent and wound, so that the volume formed after the flexible circuit board 20 is wound is relatively small.

[0039] In the embodiment of this application, the flexible circuit board 20 and the protective shell 10 can be of a split structure, and the flexible circuit board 20 can be wound and inserted into the protective shell 10. The flexible circuit board 20 is disposed in the protective shell 10, which may mean that the flexible circuit board 20 is completely accommodated in the protective shell 10, or may mean that the flexible circuit board 20 is partially accommodated in the protective shell 10.

[0040] Please refer to Figure 4 , in some embodiments, along the length direction of the protective shell 10, the flexible circuit board 20 is formed with a plurality of winding segments 21 arranged in sequence, and two adjacent winding segments 21 are partially overlapped. When the degree of deformation of the flexible circuit board 20 during winding is greater, two adjacent winding segments 21 can overlap, so that the lateral dimension formed after the flexible circuit board 20 is wound is relatively small, which is beneficial to the miniaturization of the temple 100.

[0041] Of course, in other embodiments, according to the flexibility of the flexible circuit board 20, two adjacent winding segments 21 can also be arranged at intervals, as Figure 3 shown.

[0042] In some embodiments, the number of layers of the flexible circuit board 20 is less than or equal to 3 layers. The number of layers of the flexible circuit board 20 refers to the base layer for independently arranging circuits in the thickness direction of the flexible circuit board 20 when the flexible circuit board 20 is unfolded. The number of layers of the flexible circuit board 20 being less than or equal to 3 layers makes the flexible circuit board 20 more easily deformable, and the flexible circuit board 20 is not easily caused to break during the winding process. The flexible circuit board 20 can be set to 1 layer, 2 layers or 3 layers according to the number of circuits arranged in the flexible circuit board 20. For example, when the number of circuits in the flexible circuit board 20 exceeds 20, the flexible circuit board 20 can be set as a three-layer board.

[0043] Please refer to Figure 5 and Figure 6 , in some embodiments, the temple 100 may include a support member 30 sleeved in the protective shell 10, and the flexible circuit board 20 is spirally wound around the support member 30. In this way, the support member 30 provides support for the flexible circuit board 20, so that the flexible circuit board 20 can more stably maintain a wound state, and thus can be more easily placed into the protective shell 10.

[0044] Specifically, the support member 30 is a rigid member, or rather, the support member 30 is not easily deformed. The support member 30 can be made of a rigid material such as metal. For example, in order to reduce the weight of the head-mounted device 500, the support member 30 can be made of a metal material with a relatively low density such as titanium alloy.

[0045] The shape of the support member 30 can be substantially the same as the shape of the protective shell 10, so that the support member 30 with the flexible circuit board 20 can be inserted into the protective shell 10. In the embodiment of the present application, the support member 30 is also in a long strip shape. In one example, during the assembly of the temple 100, the flexible circuit board 20 can be wound around the support member 30 first, and then the support member 30 with the flexible circuit board 20 can be inserted into the protective shell 10, thereby obtaining the temple 100.

[0046] Furthermore, the flexible circuit board 20 can be fixedly connected to the support member 30 by means of adhesion. For example, an adhesive 31 can be coated on the support member 30, and then the flexible circuit board 20 can be wound around the support member 30 so that the adhesive 31 can paste and fix the flexible circuit board 20 on the flexible circuit board 20, as Figure 5 shown. In this way, the flexible circuit board 20 can maintain the wound state more stably, making it easier for the support member 30 with the flexible circuit board 20 to be placed into the protective shell 10.

[0047] In some embodiments, the flexible circuit board 20 is adhesively fixed to both ends in the length direction of the support member 30. It can be understood that when the flexible circuit board 20 is wound around the support member 30, the flexible circuit board 20 is likely to come loose at both ends of the support member 30. Therefore, adhesively fixing the flexible circuit board 20 to both ends in the length direction of the support member 30 can prevent the flexible circuit board 20 from coming loose from the support member 30, which is beneficial for the flexible circuit board 20 to maintain the spiral wound state on the support member 30.

[0048] Please refer to Figure 7 , in some embodiments, the temple 100 includes a functional device 40, and the functional device 40 is disposed in the protective shell 10. The functional device 40 is electrically connected to the flexible circuit board 20. In this way, the flexible circuit board 20 can communicate with the functional device 40 to enable the functional device 40 to work properly.

[0049] As Figure 8 shown, in one example, a control circuit board 202 can be disposed in the body 200, and the control circuit board 202 is electrically connected to the flexible circuit board 20. The control circuit board 202 is connected to the functional device 40 through the flexible circuit board 20. In this way, the control circuit board 202 can communicate with the functional device 40 through the flexible circuit board 20 to control the normal operation of the functional device 40.

[0050] The functional device 40 includes at least one of a speaker, an antenna, and a sensor. As Figure 9 shown, if the functional device 40 is a speaker, when the head-mounted device 500 is worn on the user's head, the speaker can emit sound. The speaker can, for example, play a song or indicate the usage status of the head-mounted device 500. If the functional device 40 is an antenna, the head-mounted device 500 can transmit and receive signals through the antenna.

[0051] The sensor is, for example, a light sensor, etc. If the functional device 40 is a light sensor, the head-mounted device 500 can detect the ambient light brightness through the light sensor to adjust the display brightness of the head-mounted device 500.

[0052] It should be noted that in the Figure 8 example, the flexible circuit board 20 is only shown in one temple 100. It can be understood that the other temple 100 can also have a flexible circuit board 20.

[0053] In some embodiments, the functional device 40 is located at the end of the temple 100 in the length direction. Specifically, the functional device 40 is located at one end of the temple 100 away from the body 200. Specifically, as discussed above, a bending portion 11 is formed at one end of the temple 100, and the bending portion 11 is used to rest on the user's ear. Therefore, in order to make the bending portion 11 rest on the ear more stably, the size of the bending portion 11 is generally larger. In other words, the size of one end of the temple 100 away from the body 200 is larger. Therefore, by disposing the functional device 40 at one end of the temple 100 away from the body 200, there is sufficient space for the arrangement of the functional device 40.

[0054] Please refer to Figure 10 , in some embodiments, the body 200 further includes a top wall 210, a bottom wall 212, and a side wall 214. A notch 216 is formed in the middle of the bottom wall 212 facing the top wall 210. Or rather, the body 200 is generally in a "B" shape. When the user wears the head-mounted device 500, the head-mounted device 500 can be rested on the user's nose bridge through the notch 216, which can not only ensure the stability of the head-mounted device 500 but also ensure the comfort of the user's wearing.

[0055] Please refer to Figure 10 and Figure 11 , in some embodiments, a display 300, a light guide component 400, and a light quantity adjustment component 450 can be disposed in the body 200. The light guide component 400 is separately disposed from the display 300. That is to say, the head-mounted device 500 can be a head-mounted display device, and the head-mounted device 500 can display a picture.

[0056] The light guide component 400 includes opposite first and second sides 410 and 420. The light guide component 400 is configured to introduce the light generated by the display 300 and emit it from the second side 420. The light quantity adjustment component 450 is disposed on the first side 410, and the light quantity adjustment component 450 is configured to adjust the ambient light quantity incident on the second side 420.

[0057] In related augmented reality devices, a user can view the content displayed by the augmented reality device in a real-world scene through the augmented reality device. It can be understood that the ambient light and the light formed by the augmented reality display device enter the human eye simultaneously. If the brightness of the ambient light is relatively high, the contrast between the display brightness of the augmented reality device and the ambient brightness is too low, making it difficult for the human eye to clearly see the content displayed by the augmented reality device. If the brightness of the ambient light is relatively low, the contrast between the display brightness of the augmented reality device and the ambient brightness is too high, and the display content of the virtual reality device is likely to stimulate the user, causing eye fatigue.

[0058] To address the problem of the contrast between the display brightness of the augmented reality device and the ambient brightness being too high or too low, related technologies generally adjust the display brightness of the augmented reality device. However, when the ambient brightness is high, in order to improve the clarity of the image observed by the human eye, if the display brightness of the augmented reality device is increased, the power consumption of the augmented reality device is relatively large, generating a large amount of heat and affecting the user experience.

[0059] In the head-mounted device 500 according to the embodiment of the present application, the light quantity adjustment component 450 can adjust the ambient light quantity incident from the first side 410 and emitted from the second side 420, thereby reducing the influence of the ambient light quantity on the light generated by the display 300 and emitted from the second side 420, which is beneficial for the user to view the content displayed by the display 300 and improves the user experience.

[0060] It can be understood that when the user wears the head-mounted device 500, the human eye is located outside the second side 420. Therefore, the light generated by the display 300 can enter the human eye after being emitted from the second side 420, enabling the user to observe the image displayed by the display 300.

[0061] The ambient light enters the human eye after passing through the light quantity adjustment component 450, the first side 410, and the second side 420 in sequence, enabling the user to see the ambient objects. Therefore, the light quantity adjustment component 450 of the present application can adjust the ambient light entering the human eye, thereby reducing the influence of the ambient light on the image observed by the human eye.

[0062] Specifically, in the present embodiment, the display 300 includes an OLED display screen. The OLED display screen does not require a backlight, which is beneficial for the thinning and lightening of the head-mounted device 500. Moreover, the OLED screen has a large viewing angle and low power consumption, which is beneficial for saving power.

[0063] Of course, the display 300 can also be an LED display or a Micro LED display. These displays 300 are only examples and the embodiments of the present application are not limited thereto.

[0064] The light quantity adjustment component 450 can be a liquid crystal component or an electrochromic component. It can be understood that the liquid crystal component can change its own light transmittance by changing the orientation of the liquid crystal. The electrochromic component can change its own color and thus its light transmittance after a voltage is applied.

[0065] In the description of this specification, the description with reference to terms such as "one embodiment", "certain embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0066] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the claims and their equivalents.
