Description

[0001] Case information

[0002] This application is a divisional case based on the Chinese patent application "filed on December 7, 2023, with application number 202311676895.6 and named "A temple assembly and a head-mounted display device", and all its contents are incorporated into this application by reference. Technical Field

[0003] The present invention relates to the technical field of intelligent wearable devices, and in particular to a temple assembly and a head-mounted display device. Background Art

[0004] The temples of AR glasses are different from those of traditional glasses. In addition to the human-machine experience of wearing comfort, they are also the carriers of the functional hardware of AR glasses. The main board, buttons, microphones, speakers, etc. are mostly assembled on the temples. The assembly method will directly affect the product's acoustic performance and other product functional experiences. In addition, the appearance of the temples also directly affects the appearance and market value of the glasses.

[0005] The temples of existing AR glasses are all made of plastic shells inside and outside, which have the advantages of being light, easy to shape and produce, and easy to assemble the internal hardware. However, plastic temples are not as good as metal temples in terms of product texture experience. At the same time, the inner and outer shells of the temples are generally assembled with screws, buckles and glue. The splicing lines on the surface make it difficult for the product to ensure an extremely simple appearance while having good structural strength.

[0006] In order to achieve the above goals and pursue the ultimate beauty of product appearance, AR glasses developers must break the original structure and develop one-piece temples. The one-piece temple assembly generally adopts the form of one-piece shell + one-piece plug-in internal functional skeleton, that is, various functional hardware are integrated on a skeleton, and then inserted into the one-piece shell together.

[0007] Since the integrated functional frame has an irregular shape and occupies a large space, it is difficult to ensure the simple appearance of the product by adopting an integrated plug-in assembly method. While ensuring the simple appearance of the product, it is difficult to assemble the internal hardware by an integrated plug-in assembly method due to the limitation of the shape of the temples. Summary of the invention

[0039] Please refer to Figures 1 to 4 The present invention proposes a temple assembly 10, which is applied to a head-mounted display device. The temple assembly 10 includes a temple 100 and a first functional module 200. The temple 100 includes a main body 110. The main body 110 is integrally formed with a mounting cavity. The mounting cavity runs through the opposite ends of the main body 110 along the length direction of the temple 100, and a first mounting port 111 and a second mounting port 112 are respectively formed on two end surfaces of the main body 110; the first functional module 200 includes at least two of a speaker module 210, a pickup module 220, a button module 230 and a main control board module 240, and at least two of the first functional modules 200 are independently arranged, and the first functional module 200 can be at least partially installed into the mounting cavity from the first mounting port 111.

[0040] Specifically, the temple assembly 10 includes a temple 100 and a first functional module 200. The temple 100 includes a main body 110, and the mounting cavity of the main body 110 is used to accommodate the first functional module 200. The main body 110 is integrally formed, so that the outer surface of the main body 110 has no splicing line, and compared with the prior art method of splicing the left and right shells, it has a simpler appearance design.

[0041] The first functional module 200 includes at least two of the speaker module 210, the pickup module 220, the button module 230 and the main control board module 240, and at least two of the first functional modules 200 are independently arranged and can be respectively installed in the installation cavity from the first installation port 111 of the main body 110. That is, the speaker module 210, the pickup module 220, the button module 230 and the main control board module 240 can all be separately arranged. It is also possible that two of the modules are arranged in an integrated manner, such as the pickup module 220 and the button module 230 are relatively small in size and can be arranged in an integrated manner; or at least one of the pickup module 220 and the button module 230 is integrated in the main control board module 240.

[0042] Therefore, on the basis of the more concise appearance design of the temple of the present invention, compared with the prior art in which the speaker module 210, the microphone module 220, the button module 230 and the main control board module 240 are configured as an integrated module (that is, multiple functional hardware are integrated on one skeleton), the present invention configures at least two of the speaker module 210, the microphone module 220, the button module 230 and the main control board module 240 in the first functional module 200 as independently arranged modules. Since the independent modules are not constrained by each other and can be assembled freely, it is beneficial to load them into the installation cavity from the first installation port 111, thereby realizing the assembly of the internal hardware of the temple assembly 10 under the simple appearance of the temple 100.

[0043] In one embodiment, the middle portion of the main body 110 has a wearing section 116, and the wearing section 116 can be placed on the ear. The installation cavity includes a first cavity section 113 and a second cavity section 114 which are arranged on the same side of the wearing section 116 and are connected to each other. The second cavity section 114 is away from the wearing section 116 and is provided with a first installation port 111. The cross-sectional area of ​​the first cavity section 113 gradually decreases towards the direction approaching the wearing section 116, and the first functional module 200 is at least partially embedded in the first cavity section 113.

[0044] Please refer to Figure 4 The wearing section 116 is roughly arc-shaped, and the cross-sectional area of ​​the first cavity section 113 gradually decreases toward the wearing section 116. The lower side wall of the first cavity section 113 is arc-shaped, which is aesthetically pleasing. On the one hand, it can adapt to the shape of the ear to improve the user's wearing comfort; on the other hand, it can reduce the weight of the first cavity section 113 to achieve lightweight temple 100. In addition, since the cross-sectional area of ​​the first cavity section 113 gradually decreases in the direction from the second cavity section 114 to the first cavity section 113, the first cavity section 113 is tapered and has a positioning function. After the first functional module 200 is installed into the installation cavity from the first installation port 111, it can stop at the first cavity section 113 to avoid interference with the second functional module 300.

[0045] In one embodiment, the first functional module 200 includes a speaker module 210 and a pickup module 220. The speaker module 210 is disposed in the first cavity section 113. The first cavity section 113 is provided with a sound outlet hole 1131. The sound outlet hole 1131 is connected to the sound cavity of the speaker module 210. The pickup module 220 is disposed in the second cavity section 114. The second cavity section 114 is provided with a sound pickup hole 1141. The sound pickup hole 1141 is connected to the sound cavity of the pickup module 220.

[0046] Please refer to Figures 2 to 4The first functional module 200 includes a speaker module 210 and a pickup module 220. The speaker module 210 is usually used to emit sound, and the pickup module 220 is used to receive sound or sound waves. The speaker module 210 is arranged in the first cavity section 113, and the first cavity section 113 is provided with a sound outlet hole 1131 connected to the sound cavity of the pickup module 220, so that the sound can be transmitted from the speaker module 210 through the sound outlet hole 1131. Moreover, the speaker module 210 is arranged in the first cavity section 113, and the speaker module 210 is closer to the wearing section 116 and the ear, so that the ear can receive audio better, and the privacy is also better, thereby improving the user's experience. The second cavity section 114 is provided with a pickup hole 1141, and the sound can be transmitted from the external environment to the pickup module 220 through the pickup hole 1141. The microphone module 220 is disposed in the second cavity section 114, which can prevent the sound from being directly transmitted from the speaker module 210 to the microphone module 220, thereby avoiding interference. Since the first mounting opening 111 is disposed in the second cavity section 114, when assembling the temple assembly 10, the speaker module 210 can be first installed into the first cavity section 113 from the first mounting opening 111, and then the microphone module 220 can be installed into the second cavity section 114 from the first mounting opening 111.

[0047] In one embodiment, the installation cavity also includes a third cavity section 115 having a second installation port 112. The third cavity section 115 is arranged on a side of the wearing section 116 away from the first cavity section 113. The third cavity section 115 is connected to the first cavity section 113 on the wearing section 116. The second functional module 300 can be at least partially loaded into the third cavity section 115 from the second installation port 112, and the second functional module 300 is electrically connected to the first functional module 200.

[0048] Please refer to Figure 4 Since a first mounting port 111 and a second mounting port 112 communicating with the mounting cavity are respectively formed at both ends of the main body 110, the first functional module 200 can be at least partially loaded into the mounting cavity from the first mounting port 111, and the second functional module 300 can be at least partially loaded into the mounting cavity from the second mounting port 112, so that the space between the first mounting port 111 and the second mounting port 112 in the mounting cavity can be used to install functional modules, so that the space at the rear end of the temple 100 can be fully utilized to install more functional modules, thereby enriching the functionality of the temple assembly 10.

[0049] In addition, under the premise of a simple appearance, since the functional modules can be installed from both the first installation port 111 and the second installation port 112, on the one hand, the restriction on the installation order of the first functional module 200 and the second functional module 300 is removed, and there is no need to install the second functional module 300 first and then install the first functional module 200; on the other hand, the difficulty of installing the second functional module 300 is reduced. When installing the second functional module 300, the second functional module 300 does not need to go deep from the open end of the temple 100 to the tail end of the temple 100, which greatly improves the convenience of installing the first functional module 200 and the second functional module 300.

[0050] The second functional module 300 may be an external connection module 310 for connecting to an external device, or may be a power supply module for supplying power to the first functional module 200.

[0051] Specifically and optionally, the second functional module 200 includes an external module 310, which is used to transmit power and / or communication. The temple assembly 10 also includes a first conductive circuit 400, which passes through the first cavity section 113 and the third cavity section 115 and is electrically connected to the speaker module 210 and the external module 310.

[0052] The conductive circuit is a circuit or electronic component related to electrical conductivity, and may specifically be an FPC (Flexible Printed Circuit) or a spiral conductive wire bundle, so that the first conductive circuit can be stretched, retracted and bent during the assembly process.

[0053] Please refer to Figures 2 to 4 The second cavity section 114, the first cavity section 113, and the third cavity section 115 are sequentially arranged and connected in the direction from the first installation opening 111 to the second installation opening 112 to form an installation cavity. The first conductive circuit 400 is a circuit or electronic component related to electrical conductivity, and can be specifically an FPC (Flexible Precision Circuit) or a spiral conductive wire bundle, so that the first conductive circuit 400 can be stretched, retracted, and bent during the assembly process. The external module 310 is arranged in the third cavity section 115, and the first conductive circuit 400 is passed through the first cavity section 113 and the third cavity section 115, and is used to be electrically connected to the speaker module 210 and the external module 310 to realize the transmission of power and / or communication between the speaker module 210 and the external module 310. Although the first functional module 200 and the second functional module 300 are separately arranged, communication and power transmission between the first functional module 200 and the second functional module 300 can still be achieved through the connection of the first conductive line 400 .

[0054] In one embodiment, the cross-sectional area of ​​the third cavity segment 115 gradually decreases toward the wearing segment 116 .

[0055] Please refer to Figure 4 The middle part of the main body 110 has a wearing section 116, and the shape of the wearing section 116 can be adapted to the ear, ensuring that the product can be firmly placed on the ear, maintaining stable wearing while improving the comfort and experience of the user. The third cavity section 115 has a second mounting port 112, which allows the connection of other components or the installation of other functional modules, and can make full use of the space at the end of the temple 100, providing the possibility for enriching the functional expansion of the temple assembly 10. The cross-sectional area of ​​the third cavity section 115 gradually decreases toward the direction close to the wearing section 116. The lower side wall of the third cavity section 115 is arc-shaped, which has an aesthetic feeling. On the one hand, it can adapt to the shape of the ear to improve the comfort of the user's wearing; on the other hand, it can reduce the weight of the third cavity section 115 to achieve lightweight temple 100. In addition, since the cross-sectional area of ​​the third cavity section 115 gradually decreases toward the direction close to the wearing section 116, the third cavity section 115 is tapered and has a positioning function. After the second functional module 300 is installed into the installation cavity from the second installation opening 112 , it can stop at the third cavity section 115 to avoid interference with the first functional module 200 .

[0056] In one embodiment, the speaker module 210 includes a first frame 211 and a speaker unit 212 disposed on the first frame 211 , and the pickup module 220 includes a second frame 221 and a pickup unit 222 disposed on the second frame 221 . The first frame 211 is adapted to be embedded in the first cavity section 113 .

[0057] Please refer to Figure 2 and Figure 5 The speaker module 210 includes a first frame 211 and a speaker unit 212 disposed on the first frame 211. The speaker unit 212 is a device for emitting sound, and the speaker unit 212 is mounted on the first frame 211. The size and shape of the first frame 211 are adapted to the first cavity section 113, and at least partially embedded in the first cavity section 113, ensuring that the speaker unit 212 is placed in a suitable position to effectively propagate sound. The pickup module 220 includes a second frame 221 and a pickup unit 222 disposed on the second frame 221. The pickup unit 222 is used to receive sound or sound waves and convert them into electrical signals. The pickup unit 222 is disposed on the second frame 221, and the second frame 221 is disposed in the second cavity section 114, ensuring that the pickup unit 222 is stably located on the sound propagation path to effectively capture sound from the external environment.

[0058] In one embodiment, the first skeleton 211 is provided with an abutment portion 2111 at one end away from the first mounting opening 111. When the first skeleton 211 is inserted into the first cavity section 113, one end of the tooling bracket 20 can pass through the second mounting opening 112 and the third cavity section 115 and abut against the abutment portion 2111 to align the sound cavity of the speaker unit 212 with the sound outlet hole 1131.

[0059] Please refer to Figure 2 and Figure 5 The first frame 211 has an abutment portion 2111 at one end away from the first mounting opening 111, and the abutment portion 2111 is used to connect with the tooling bracket 20. This abutment portion 2111 is usually located at the end of the first frame 211 and faces the second mounting opening 112, and can be abutted by the tooling bracket 20. The tooling bracket 20 can be inserted into the first cavity section 113 from the second mounting opening 112 to locate the correct position of the speaker module 210 in the first cavity section 113. One end of the tooling bracket 20 can pass through the second mounting opening 112 and the third cavity section 115, so as to abut against the abutment portion 2111 when the first frame 211 is inserted into the first cavity section 113. The abutment between the tooling bracket 20 and the abutment portion 2111 ensures that the sound cavity of the speaker unit 212 is aligned with the sound outlet hole 1131, thereby ensuring that the sound emitted from the speaker unit 212 can be effectively transmitted through the sound outlet hole 1131 without being affected by the misalignment of the sound cavity of the speaker unit 212 and the sound outlet hole 1131.

[0060] In one embodiment, the temple assembly 10 further includes a grille cover 600 , which is at least partially embedded in the sound outlet hole 1131 and connected to the first frame 211 and the wall of the sound outlet hole 1131 via an adhesive structure.

[0061] Please refer to Figure 1 and Figure 5The grille mesh cover 600 is a component with a grid-like or open-hole structure, which is generally used to cover or protect the sound outlet hole 1131. The presence of the grille mesh cover 600 helps to control the propagation and scattering of sound, and has decorative and protective functions. The grille mesh cover 600 is at least partially embedded in the sound outlet hole 1131, and a part or all of the grille mesh cover 600 is placed in the area of ​​the sound outlet hole 1131 to ensure that the grille mesh cover 600 is tightly connected to the hole wall of the sound outlet hole 1131, and to ensure that the grille mesh cover 600 is aligned with the sound outlet hole 1131, thereby helping to reduce unnecessary interference or obstruction to the sound during propagation. The grille mesh cover 600 is connected to the first frame 211 and the hole wall of the sound outlet hole 1131 through an adhesive structure. The adhesive structure is used to firmly connect the grille mesh cover 600 to the first frame 211 and the hole wall of the sound hole 1131, ensuring a firm connection between the grille mesh cover 600 and the first frame 211 and the hole wall of the sound hole 1131, while avoiding the connection between the sound cavity of the speaker module 210 and the gap between the first frame 211 and the inner wall of the installation cavity, so as to achieve the sealing of the speaker module 210.

[0062] In one embodiment, two sound outlet holes 1131 are provided, one sound outlet hole 1131 is provided on the upper surface of the main body 110 , and the other sound outlet hole 1131 is provided on the lower surface of the main body 110 .

[0063] Please refer to Figure 1 and Figure 4 The main body 110 is designed to have two sound outlets 1131 to achieve sound output. One sound outlet 1131 is located on the upper surface of the main body 110, and the sound can be output from the top of the main body 110; while the other sound outlet 1131 is located on the lower surface of the main body 110, and the sound can be output from the bottom of the main body 110, so that the sound can be output from two different positions and directions of the main body 110, which can achieve more flexible and diverse sound output methods, so as to adapt to different application scenarios, such as sound systems, communication equipment or audio equipment, and can also improve the coverage of the sound, improve the stereoscopic effect of the sound, or meet specific acoustic performance requirements.

[0064] In one embodiment, the first functional module 200 also includes a key module 230 disposed in the second cavity segment 114, the key module 230 includes a third frame and a key unit 231 disposed in the third frame, the second cavity segment 114 is provided with a key via 1142, and the key unit 231 is at least partially exposed in the key via 1142.

[0065] Please refer to Figure 4 and Figure 6The first functional module 200 further includes a key module 230 for user interaction with the product.
