Description
[0001] Divisional case information
[0002] This application is a divisional case based on the Chinese patent application filed on December 7, 2023, with the application number 202311676895.6 and the title "A temple assembly and a head-mounted display device", and all its content is incorporated herein by reference. Technical field
[0003] The present invention relates to the technical field of intelligent wearable devices, and particularly relates to a temple assembly and a head-mounted display device. Background technique
[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. Most of the main board, buttons, microphones, speakers, etc. are assembled relying on the temples, and their assembly methods will directly affect the product functional experiences such as the acoustic performance of the product. In addition, the aesthetic appearance of the temples also directly affects the appearance and market value of the glasses.
[0005] The existing temples of AR glasses are all internal and external plastic shell structures, and their advantages are light weight, easy to shape and produce, and easy to assemble internal hardware. However, plastic temples are inferior to metal temples in terms of the product texture experience. At the same time, the internal and external shells of the temples are generally assembled using screws, buckles and adhesives, and the appearance splicing lines make it difficult for the product to achieve an extremely simple appearance while having good structural strength.
[0006] In order to achieve the above goals and pursue the ultimate beauty of the product appearance, AR glasses developers must break the original structure and develop an integrated temple. The assembly of the integrated temple generally adopts the form of an integrated outer shell + an integrally inserted internal functional skeleton, that is, each functional hardware is integrated on a skeleton and then inserted into the integrated outer shell together.
[0007] Due to the irregular shape and large space occupation of the integrated functional skeleton, it is difficult to ensure the simple appearance of the product by adopting the integrally inserted assembly form. While ensuring the simple appearance of the product, due to the limitation of the temple shape, it is also difficult to realize the assembly of internal hardware through the integrally inserted assembly method. Summary of the invention
[0008] The main purpose of the present invention is to propose a temple assembly, aiming to realize the assembly of internal functional hardware of the temple assembly under the simple appearance of the temple.
[0009] The technical solution of the present invention proposes a temple assembly applied to a head-mounted display device, and the temple assembly includes:
[0010] The temple, including a main body portion, is integrally formed with an installation cavity. The installation cavity penetrates through opposite ends of the main body portion along the length direction of the temple, and a first installation opening and a second installation opening are respectively formed on two end faces of the main body portion;
[0011] The first functional module includes at least two of a speaker module, a pickup module, a button module, and a main control board module, and at least two of the first functional module are independently arranged. The first functional module can be at least partially inserted into the installation cavity from the first installation opening.
[0012] In one embodiment, a wearing section is provided in the middle of the main body portion. The wearing section can be abutted against the ear. The installation cavity includes a first cavity section and a second cavity section which are arranged on the same side of the wearing section and are communicated with each other. The second cavity section is far away from the wearing section and is provided with the first installation opening. The cross-sectional area of the first cavity section gradually decreases towards the direction close to the wearing section. The first functional module is at least partially embedded in the first cavity section.
[0013] In one embodiment, the first functional module includes the speaker module and the pickup module. The speaker module is arranged in the first cavity section. The first cavity section is provided with a sound outlet hole which is communicated with the sound cavity of the speaker module. The pickup module is arranged in the second cavity section. The second cavity section is provided with a pickup hole which is communicated with the sound cavity of the pickup module.
[0014] In one embodiment, the installation cavity further includes a third cavity section provided with the second installation opening. The third cavity section is arranged on the side of the wearing section far away from the first cavity section. The third cavity section is communicated with the first cavity section on the wearing section;
[0015] The temple assembly further includes an external module and a first conductive circuit. The external module is used for transmitting power and / or communication and can be at least partially inserted into the third cavity section from the second installation opening. The first conductive circuit is disposed through the first cavity section and the third cavity section and is electrically connected to the speaker module and the external module.
[0016] In one embodiment, the speaker module includes a first skeleton and a speaker unit disposed on the first skeleton. The pickup module includes a second skeleton and a pickup unit disposed on the second skeleton. The first skeleton is adaptively embedded in the first cavity section.
[0017] In one embodiment, the first skeleton is provided with an abutting portion at one end far away from the first installation opening. When the first skeleton is inserted into the first cavity section, one end of a tooling bracket can pass through the second installation opening and the third cavity section and abut against the abutting portion, so that the sound cavity of the speaker unit is aligned with the sound outlet hole.
[0018] In one embodiment, the first functional module further includes a key module disposed in the second cavity section. The key module includes a third skeleton and a key unit disposed on the third skeleton. The second cavity section is provided with a key through hole, and at least a part of the key unit is exposed in the key through hole.
[0019] In one embodiment, the first functional module further includes a main control board module disposed in the second cavity section. The main control board module includes a fourth skeleton and a main control board unit disposed on the fourth skeleton. The first conductive line is also electrically connected to the main control board unit.
[0020] In one embodiment, the temple assembly further includes a second conductive line, which is disposed in the first cavity section and on the second skeleton. The speaker module and the key module are electrically connected to the main control board module through the second conductive line.
[0021] In one embodiment, the first skeleton and the second skeleton are separately provided. The middle part of the first conductive line is disposed on the first skeleton. When the first skeleton is inserted into the first cavity section from the first installation opening, the first end of the first conductive line can sequentially pass through the second cavity section, the first cavity section, and the third cavity section, and extend to the second installation opening.
[0022] The present invention also provides a head-mounted display device, including the foregoing temple assembly.
[0023] The technical solution of the present invention integrally forms the main body part, so that there is no any splicing line on the outer surface of the main body part. Compared with the prior art that uses the method of splicing the left and right shells, it has a more concise appearance design. On this basis, compared with the prior art in which the speaker module, the pickup module, the key module, and the main control board module 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, the pickup module, the key module, and the main control board module in the first functional module as independent modules. Since the independent modules are not restricted by each other and can be freely assembled, it is beneficial to install them into the installation cavity from the first installation opening, so that the internal hardware of the temple assembly can be assembled under the simple appearance of the temple.

[0039] Please refer to Figures 1 to 4 , the present invention provides 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 portion 110. An installation cavity is integrally formed in the main body portion 110. The installation cavity penetrates through opposite ends of the main body portion 110 along the length direction of the temple 100, and a first installation opening 111 and a second installation opening 112 are respectively formed on two end faces of the main body portion 110; the first functional module 200 includes at least two of a speaker module 210, a microphone module 220, a button module 230, and a main control board module 240, and at least two of the first functional module 200 are independently arranged, and the first functional module 200 can be at least partially inserted into the installation cavity from the first installation opening 111.
[0040] Specifically, the temple assembly 10 includes a temple 100 and a first functional module 200. The temple 100 includes a main body portion 110. The installation cavity of the main body portion 110 is used to accommodate the first functional module 200. The main body portion 110 is integrally formed, so that there is no any splicing line on the outer surface of the main body portion 110, and compared with the prior art method of splicing left and right shells, it has a more concise appearance design.
[0041] The first functional module 200 includes at least two of a speaker module 210, a microphone module 220, a button module 230, and a main control board module 240, and at least two of the first functional module 200 are independently arranged and can be respectively inserted into the installation cavity from the first installation opening 111 of the main body portion 110. That is, the speaker module 210, the microphone 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 integrally arranged. For example, the microphone module 220 and the button module 230 are small in volume and can be arranged integrally; or at least one of the microphone module 220 and the button module 230 is integrated in the main control board module 240.
[0042] Therefore, on the basis that the temple of the present invention has a more concise appearance design, compared with the prior art in which the speaker module 210, the pickup module 220, the button module 230, and the main control board module 240 are configured as an integrated module (i.e., multiple functional hardware are integrated on one skeleton), in the present invention, at least two of the speaker module 210, the pickup module 220, the button module 230, and the main control board module 240 in the first functional module 200 are independently provided modules. Since the independent modules are not restricted by each other and can be freely assembled, it is beneficial to be inserted into the installation cavity from the first installation opening 111, so that the internal hardware of the temple assembly 10 can be assembled under the simple appearance of the temple 100.
[0043] In an embodiment, the middle part of the main body portion 110 has a wearing section 116 which can be abutted against 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 communicate with each other. The second cavity section 114 is away from the wearing section 116 and is provided with a first installation opening 111. The cross-sectional area of the first cavity section 113 gradually decreases in the direction close to the wearing section 116, and at least part of the first functional module 200 is embedded in the first cavity section 113.
[0044] Please refer to Figure 4 , the wearing section 116 is generally arc-shaped. The cross-sectional area of the first cavity section 113 gradually decreases in the direction close to the wearing section 116. The lower side wall of the first cavity section 113 is arc-shaped, which has aesthetic feeling. On the one hand, it can adapt to the shape of the ear to improve the comfort of the user wearing; on the other hand, it can reduce the weight of the first cavity section 113 to realize the light weight of the 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 in a tapered shape and has a positioning function. After the first functional module 200 is inserted into the installation cavity from the first installation opening 111, it can stop at the first cavity section 113 to avoid interference with the second functional module 300.
[0045] In an embodiment, the first functional module 200 includes a speaker module 210 and a pickup module 220. The speaker module 210 is arranged in the first cavity section 113. The first cavity section 113 is provided with a sound outlet hole 1131 which communicates with the sound cavity of the speaker module 210. The pickup module 220 is arranged in the second cavity section 114. The second cavity section 114 is provided with a pickup hole 1141 which communicates with the sound cavity of the pickup module 220.
[0046] Please refer to Figures 2 to 4, the first functional module 200 includes a speaker module 210 and a pickup module 220. The speaker module 210 is generally used to emit sound, and the pickup module 220 is used to receive sound or sound waves. The speaker module 210 is disposed in the first cavity section 113, and the first cavity section 113 is provided with a sound outlet hole 1131 communicating with the sound cavity of the pickup module 220, so that sound can be transmitted out of the speaker module 210 through the sound outlet hole 1131. Moreover, the speaker module 210 is disposed in the first cavity section 113. The speaker module 210 is closer to the wearing section 116 and closer to the ear, resulting in a better audio reception effect for the ear and better privacy, thereby improving the user experience. A sound pickup hole 1141 is provided in the second cavity section 114, and sound can be transmitted from the external environment to the pickup module 220 through the sound pickup hole 1141. The pickup module 220 is disposed in the second cavity section 114, which can prevent sound from directly transmitting from the speaker module 210 to the pickup module 220, thus avoiding interference. Since the first mounting opening 111 is provided in the second cavity section 114, when assembling the temple assembly 10, the speaker module 210 can be first inserted into the first cavity section 113 from the first mounting opening 111, and then the pickup module 220 can be inserted into the second cavity section 114 from the first mounting opening 111.
[0047] In an embodiment, the installation cavity further includes a third cavity section 115 provided with a second mounting opening 112. The third cavity section 115 is disposed on a side of the wearing section 116 away from the first cavity section 113. The third cavity section 115 communicates with the first cavity section 113 on the wearing section 116. The second functional module 300 can be at least partially inserted into the third cavity section 115 from the second mounting opening 112, and the second functional module 300 is electrically connected to the first functional module 200.
[0048] Please refer to Figure 4 , since the first mounting opening 111 and the second mounting opening 112 communicating with the installation cavity are respectively formed at both ends of the main body portion 110, the first functional module 200 can be at least partially inserted into the installation cavity from the first mounting opening 111, and the second functional module 300 can be at least partially inserted into the installation cavity from the second mounting opening 112. Thus, the space between the first mounting opening 111 and the second mounting opening 112 in the installation cavity can be used to install functional modules, so as to make full use of the space at the end of the temple 100 and install more functional modules, thereby enriching the functionality of the temple assembly 10.
[0049] In addition, on 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 limitation 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 the first functional module 200; on the other hand, the installation difficulty of the second functional module 300 is reduced. When installing the second functional module 300, the second functional module 300 does not need to extend 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 can be an external connection module 310 for connecting to an external device, or 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 connection module 310, and the external connection module 310 is used to transmit power and / or communication. The temple assembly 10 further includes a first conductive line 400, and the first conductive line 400 is disposed through the first cavity section 113 and the third cavity section 115 and is electrically connected to the speaker module 210 and the external connection module 310.
[0052] The conductive line is a line or electronic component related to conductivity, and specifically can be an FPC (Flexible Printed Circuit, flexible printed circuit board) or a spiral conductive wire bundle, so that the first conductive line 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 arranged in sequence and communicated in the direction from the first installation port 111 to the second installation port 112 to form an installation cavity. The first conductive line 400 is a line or electronic component related to conductivity, and specifically can be an FPC (Flexible Printed Circuit, flexible printed circuit board) or a spiral conductive wire bundle, so that the first conductive line 400 can be stretched, retracted and bent during the assembly process. The external connection module 310 is disposed in the third cavity section 115, and the first conductive line 400 is disposed 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 connection module 310 to realize the transmission of power and / or communication between the speaker module 210 and the external connection module 310. Although the first functional module 200 and the second functional module 300 are separately arranged, through the connection of the first conductive line 400, the communication and power transmission between the first functional module 200 and the second functional module 300 can still be realized.
[0054] In one embodiment, the cross-sectional area of the third cavity section 115 gradually decreases in the direction towards the wearing section 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 stably placed on the ear, improving the comfort and experience of the user while maintaining stable wearing. The third cavity section 115 has a second mounting opening 112, allowing connection to other components or installation of other functional modules, making full use of the space at the end of the temple 100 and providing the possibility for enriching the function expansion of the temple assembly 10. The cross-sectional area of the third cavity section 115 gradually decreases in the direction towards the wearing section 116, and the lower side wall of the third cavity section 115 is arc-shaped, having aesthetic feeling. On the one hand, it can be adapted to the shape of the ear to improve the comfort of the user wearing; on the other hand, it can reduce the weight of the third cavity section 115 to achieve the light weight of the temple 100. In addition, since the cross-sectional area of the third cavity section 115 gradually decreases in the direction towards the wearing section 116, the third cavity section 115 is in a tapered shape and has a positioning function. After the second functional module 300 is loaded into the installation cavity from the second mounting 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 skeleton 211 and a speaker unit 212 provided on the first skeleton 211, and the pickup module 220 includes a second skeleton 221 and a pickup unit 222 provided on the second skeleton 221. The first skeleton 211 is adaptively embedded in the first cavity section 113.
[0057] Please refer to Figure 2 and Figure 5 , the speaker module 210 includes a first skeleton 211 and a speaker unit 212 provided on the first skeleton 211. The speaker unit 212 is a device for emitting sound, and the speaker unit 212 is installed on the first skeleton 211. The size and shape of the first skeleton 211 are adapted to the first cavity section 113 and are at least partially embedded in the first cavity section 113 to ensure that the speaker unit 212 is placed in a suitable position to effectively transmit sound. The pickup module 220 includes a second skeleton 221 and a pickup unit 222 provided on the second skeleton 221. The pickup unit 222 is used to receive sound or sound waves and convert them into electrical signals. The pickup unit 222 is provided on the second skeleton 221, and the second skeleton 221 is provided in the second cavity section 114 to ensure 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 framework 211 is provided with an abutting portion 2111 at one end far from the first mounting opening 111. When the first framework 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 abutting portion 2111, so that the sound cavity of the speaker unit 212 is aligned with the sound outlet hole 1131.
[0059] Please refer to Figure 2 and Figure 5 , an abutting portion 2111 is provided at one end of the first framework 211 far from the first mounting opening 111, and the abutting portion 2111 is used for connecting with the tooling bracket 20. This abutting portion 2111 is usually located at the end of the first framework 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 that when the first framework 211 is inserted into the first cavity section 113, it abuts against the abutting portion 2111. Through the abutting of the tooling bracket 20 and the abutting portion 2111, it is ensured that the sound cavity of the speaker unit 212 is aligned with the sound outlet hole 1131, so 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, and at least a part of the grille cover 600 is embedded in the sound outlet hole 1131 and is connected to the first framework 211 and the hole wall surface of the sound outlet hole 1131 through an adhesive structure.
[0061] Please refer to Figure 1 and Figure 5, the grille cover 600 is a component with a grid-like or perforated structure, usually used to cover or protect the sound outlet holes 1131. The presence of the grille cover 600 helps control the propagation and scattering of sound and has the functions of decoration and protection. The grille cover 600 is at least partially embedded in the sound outlet holes 1131, and a part or all of the grille cover 600 is placed within the area of the sound outlet holes 1131 to ensure that the grille cover 600 is tightly connected to the hole walls of the sound outlet holes 1131 and that the grille cover 600 is aligned with the sound outlet holes 1131, thereby helping to reduce unnecessary interference or obstruction to the sound during propagation. The grille cover 600 is connected to the first skeleton 211 and the hole wall surface of the sound outlet holes 1131 through an adhesive structure. The adhesive structure is used to firmly connect the grille cover 600 to the first skeleton 211 and the hole wall surface of the sound outlet holes 1131, ensuring a stable connection between the grille cover 600 and the first skeleton 211 and the hole wall surface of the sound outlet holes 1131, while preventing the sound cavity of the speaker module 210 from communicating with the gap between the first skeleton 211 and the inner wall of the installation cavity to achieve the sealing of the speaker module 210.
[0062] In one embodiment, there are two sound outlet holes 1131. One sound outlet hole 1131 is provided on the upper surface of the main body portion 110, and the other sound outlet hole 1131 is provided on the lower surface of the main body portion 110.
[0063] Please refer to Figure 1 and Figure 4 , the main body portion 110 is designed to have two sound outlet holes 1131 to achieve sound output. One sound outlet hole 1131 is located on the upper surface of the main body portion 110, and sound can be output from the top of the main body portion 110; while the other sound outlet hole 1131 is located on the lower surface of the main body portion 110, and sound can be output from the bottom of the main body portion 110. Thus, sound can be output from two different positions and directions of the main body portion 110, enabling a more flexible and diverse sound output method, which can adapt to different application scenarios, such as audio systems, communication devices, or audio equipment. It can also increase the sound coverage range, improve the sound stereoscopic effect, or meet specific acoustic performance requirements.
