Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

The following disclosure provides many different embodiments or examples for implementing different features of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

Referring to fig. 1, in the head-mounted device 500 provided in the embodiments of the present application, through cooperation of a computing system and an optical system, after a user wears the head-mounted device 500, an optical signal may be sent to eyes of the user, so as to achieve different effects of Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR).

Referring to fig. 1, a headset 500 according to an embodiment of the present disclosure includes a body 200 and temples 100, and the temples 100 are connected to the body 200.

The body 200 may be used to be worn on the front of the user's eyes, and the temples 100 may be used to be worn on the user's ears, so that the head-mounted device 500 may be stably worn on the user's head. The temples 100 may be rotatably connected with the body 200, for example, the temples 100 and the body 200 may be penetrated through by a rotation shaft, so that the temples 100 are rotatably connected to the body 200.

Since the head-mounted device 500 is adapted to be worn on the head of the user, how to make the head-mounted device 500 more compact is critical to the design of the head-mounted device 500.

Referring to fig. 2 and 3, the temple 100 according to the embodiment of the present application includes a protective case 10 and a flexible circuit board 20, and the flexible circuit board 20 is disposed in the protective case 10. The flexible circuit board 20 is spirally wound and extends along the length direction of the protective case 10.

In the temple 100 according to the embodiment of the present application, the flexible circuit board 20 is spirally wound and extended along the length direction of the protective housing 10, so that the transverse dimension formed by the flexible circuit board 20 is small, and thus the overall transverse dimension of the temple 100 is small under the condition that the flexible circuit board 20 normally supplies power or transmits signals, which is beneficial to the miniaturization design of the head-mounted device 500.

It should be noted that the lateral dimension of the temple arm 100 indicates that the temple arm 100 is taken in a plane perpendicular to the length direction of the temple arm 100, and the diameter of the circumscribed circle of the cross-sectional outer contour of the temple arm 100, as indicated by D1 in fig. 3, is the lateral dimension of the temple arm 100. Similarly, the lateral dimension of the flexible circuit board 20 refers to a diameter of a circumscribed circle of the sectional outer contour of the flexible circuit board 20, as indicated by D2 in fig. 3, when the flexible circuit board 20 is taken in a plane perpendicular to the length direction of the temple 100, the lateral dimension of the flexible circuit board 20 is formed.

Specifically, the protective case 10 may be elongated. The protective casing 10 is long, which means that the size of one direction of the protective casing 10 is much larger than the sizes of the two other directions. For example, the size of the protective case 10 in the X direction is 3 times or more the size in the Y direction and the Z direction. The outer contour of the protective case 10 may be linear or curved.

The protective case 10 is an appearance part of the temple 100, and the protective case 10 is often in contact with an external object, so that, in order to improve the wear resistance of the protective case 10, the protective case 10 may be made of a relatively wear-resistant material, for example, the material of the protective case 10 is silicon gel. In addition, since the protective case 10 is in contact with the skin of the head of the user, the protective case 10 may be made of a relatively soft material in order to increase the comfort of the user.

As shown in fig. 1 and 2, a bent portion 11 may be formed at one end of the protective shell 10 in the length direction, and the bent portion 11 may be configured to be erected on an ear of a user when the user wears the head-mounted device 500, so that the head-mounted device 500 is not easily slid.

The Flexible Printed Circuit board 20 (FPC) is a Flexible Printed Circuit board having high reliability and excellent flexibility, which is made of a polyimide or polyester film as a base material, and the Flexible Printed Circuit board 20 has the characteristics of high wiring density, light weight, thin thickness, good bendability, and the like.

Therefore, the present application uses the flexible circuit board 20 as a signal transmission element, and a plurality of independent channels can be formed to realize versatility of signal transmission. For example, one of the channels is used to carry communication signals and the other channel is used to carry power.

In addition, the flexible circuit board 20 can be bent and rolled, so that the volume formed after the flexible circuit board 20 is rolled is small.

In the embodiment of the present application, the flexible circuit board 20 may be a separate structure from the protective case 10, and the flexible circuit board 20 may be inserted into the protective case 10 after being wound. The flexible circuit board 20 is disposed in the protective case 10, and it may be referred that the flexible circuit board 20 is entirely accommodated in the protective case 10, or that the flexible circuit board 20 is partially accommodated in the protective case 10.

Referring to fig. 4, in some embodiments, the flexible circuit board 20 is formed with a plurality of winding segments 21 arranged in sequence along a length direction of the protective casing 10, and two adjacent winding segments 21 are partially overlapped. When the degree of deformation of the flexible circuit board 20 by winding is larger, the adjacent two winding sections 21 may overlap, so that the lateral dimension formed after the flexible circuit board 20 is wound is smaller, which is advantageous to miniaturizing the temple 100.

Of course, in other embodiments, two adjacent winding segments 21 may be spaced apart according to the flexibility of the flexible circuit board 20, as shown in fig. 3.

In some embodiments, the number of layers of the flexible circuit board 20 is less than or equal to 3. The number of layers of the flexible circuit board 20 refers to a base layer for independently arranging lines 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 is less than or equal to 3, so that the flexible circuit board 20 is easier to deform, and the flexible circuit board 20 is not easy to cause line breakage in the winding process. The flexible circuit board 20 may be provided in 1 layer, 2 layers or 3 layers according to the number of lines arranged in the flexible circuit board 20. For example, when the number of lines in the flexible circuit board 20 exceeds 20, the flexible circuit board 20 may be provided as a 3-layer board.

Referring to fig. 5 and 6, in some embodiments, the temple 100 may include a support 30 disposed inside the protective shell 10, and the flexible circuit board 20 is spirally wound on the support 30. In this manner, the support member 30 provides support to the flexible circuit board 20, so that the flexible circuit board 20 is more stably maintained in a wound state, thereby being more easily put into the protective case 10.

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

The support 30 may have substantially the same shape as the protective case 10 so that the support 30 with the flexible circuit board 20 may be inserted into the protective case 10. In the present embodiment, the supporting member 30 is also elongated. In one example, during the assembly of the temple 100, the temple 100 may be obtained by winding the flexible circuit board 20 on the support 30 and then inserting the support 30 with the flexible circuit board 20 into the protective case 10.

Further, the flexible circuit board 20 may be fixedly connected to the supporting member 30 by means of bonding. For example, an adhesive 31 may be coated on the support 30, and then the flexible circuit board 20 may be wound around the support 30 so that the adhesive 31 may adhesively fix the flexible circuit board 20 to the flexible circuit board 20, as shown in fig. 5. As such, the flexible circuit board 20 may be more stably maintained in a wound state, so that the support member 30 with the flexible circuit board 20 may be more easily put into the protective case 10.

In some embodiments, the flexible circuit board 20 is fixed to both ends of the support 30 in the longitudinal direction by bonding. It is understood that the flexible circuit board 20 is wound on the support member 30, and the flexible circuit board 20 is easily released at both ends of the support member 30. Therefore, the flexible circuit board 20 and the two ends of the supporting member 30 in the length direction are bonded and fixed, so that the flexible circuit board 20 is not easy to loosen from the supporting member 30, and the flexible circuit board 20 is favorable for keeping the spiral winding state on the supporting member 30.

Referring to fig. 7, in some embodiments, the temple 100 includes the functional device 40, and the functional device 40 is disposed within the protective shell 10. The functional device 40 is electrically connected to the flexible circuit board 20. In this manner, the flexible circuit board 20 can communicate with the functional device 40 to allow the functional device 40 to operate properly.

As shown in fig. 8, in one example, a control circuit board 202 may 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 functional device 40 to operate normally.

The functional device 40 includes at least one of a speaker, an antenna, and a sensor. As shown in fig. 9, if the functional device 40 is a speaker, the speaker may emit a sound when the head-mounted apparatus 500 is worn on the head of the user. The speaker may, for example, play a song or prompt the use status of the head-mounted device 500. If the functional device 40 is an antenna, the head-mounted apparatus 500 can transmit and receive signals through the antenna.

The sensor is, for example, an optical sensor or the like. If the functional device 40 is a light sensor, the head-mounted device 500 may detect the brightness of the ambient light through the light sensor to adjust the display brightness of the head-mounted device 500.

It is noted that in the example of fig. 8, the flexible circuit board 20 is shown in only one temple 100. It is understood that the other temple 100 may also have a flexible circuit board 20.

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 an end of the temple 100 remote from the body 200. Specifically, as discussed above, one end of the temple 100 is formed with the bent portion 11, and the bent portion 11 is intended to be mounted on the ear of the user, and therefore, in order to make the bent portion 11 more stably mounted on the ear, the size of the bent portion 11 is generally large. In other words, the size of the end of the temple 100 away from the body 200 is large, and therefore, the functional device 40 is provided at the end of the temple 100 away from the body 200, so that there is a sufficient space for the arrangement of the functional device 40.

Referring to fig. 10, in some embodiments, the body 200 further includes a top wall 210, a bottom wall 212, and a side wall 214. The middle of the bottom wall 212 forms a notch 216 toward the top wall 210. Alternatively, the body 200 is substantially "B" shaped. When the user wears the head-mounted device 500, the head-mounted device 500 can be erected on the bridge of the nose of the user through the notch 216, so that the stability of the head-mounted device 500 can be guaranteed, and the wearing comfort of the user can be guaranteed.

Referring to fig. 10 and 11, in some embodiments, the display 300, the light guide member 400, and the light amount adjustment member 500 may be disposed in the body 200. The light guide member 400 is disposed apart from the display 300. That is, the head mounted device 500 may be a head mounted display device, and the head mounted device 500 may display a screen.

The light guide member 400 includes first and second opposing

sides

410 and 420. The light guide member 400 serves to guide light generated from the display 300 and to emit the light from the second side 420. The light amount adjustment part 500 is disposed at the second side 420, and the light amount adjustment part 500 is used to adjust the amount of ambient light incident to the second side 420.

In a related augmented reality device, a user can see content displayed by the augmented reality device in a real scene through the augmented reality device. It can be understood that the light formed by the ambient light and the augmented reality device enters human eyes at the same time, if the light brightness of the environment is higher, the contrast between the display brightness of the augmented reality device and the ambient brightness is too low, and the display content of the augmented reality device is difficult to see by the human eyes. If the light brightness of the environment is low, the contrast between the display brightness of the augmented reality device and the environment brightness is too high, and the display content of the virtual reality device easily stimulates people to cause eye fatigue.

In order to solve the problem that the contrast between the display brightness of the augmented reality device and the ambient brightness is too high or too low, the related art generally adjusts the display brightness of the augmented reality device. However, when the ambient brightness is high, if the display brightness of the augmented reality device is increased in order to improve the image clarity observed by human eyes, the power consumption of the augmented reality device is increased, and a large amount of heat is generated to affect the user experience.

In the head-mounted device 500 according to the embodiment of the application, the light quantity adjusting part 500 can adjust the quantity of the ambient light entering from the first side 410 and exiting from the second side 420, so that the influence of the quantity of the ambient light on the light rays generated by the display 300 and exiting from the second side 420 can be reduced, the user can watch the content displayed by the display 300, and the user experience can be improved.

It is understood that when the user wears the head-mounted device 500, the human eye is positioned outside the second side 420, and thus, the light generated by the display 300 can enter the human eye after exiting from the second side 420, so that the user can observe the image displayed by the display 300.

The ambient light enters the human eye after passing through the light amount adjustment member 500, the first side 410, and the second side 420 in order, so that the user can see the environmental matters. Therefore, the light amount adjustment section 500 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.

Specifically, in this embodiment, the display 300 includes an O L ED display screen, the O L ED display screen does not need a backlight, which is beneficial to the light and thin of the headset 500, and the O L ED screen has a large viewing angle and low power consumption, which is beneficial to saving power consumption.

Of course, the display 300 may also be an L ED display or a Micro L ED display, such displays 300 are merely examples and embodiments of the present application are not limited thereto.

The light amount adjustment member 500 may be a liquid crystal member or an electrochromic member. It is understood that the liquid crystal member can change its own light transmittance by changing the deflection of the liquid crystal. The electrochromic member may change its color and thus its light transmittance after voltage is applied.
