[0022] Head-mounted display devices require a wear status detection function for power consumption control, energy efficiency optimization, and user experience. Currently, this detection is primarily performed using proximity sensors. However, optical proximity sensors are susceptible to interference from ambient light and can mistakenly detect wear status in strong sunlight, for example. This results in inaccurate wear status detection, which in turn affects the device's performance.

[0023] The present invention provides a temple assembly.

[0024] See also Figure 1 and Figure 2 In one embodiment of the present invention, the temple assembly includes a shell 100 and a main control module 200, wherein the main control module 200 is installed in the shell 100, and the main control module 200 includes a flexible circuit board 210, and a capacitive wearing detection circuit board 220 and a touch circuit board 230 electrically connected to the flexible circuit board 210 respectively. The capacitive wearing detection circuit board 220 is used to monitor the wearing status of the temple assembly, and the touch circuit board 230 is used to receive touch instructions.

[0025] Specifically, the temple assembly is one of the main components of the head-mounted display device. It is connected to the frame of the head-mounted display device and is used to overlap the ears. The temple assembly includes a housing 100 and a main control module 200, and the main control module 200 is installed in the housing 100. In one embodiment, a receiving cavity is formed in the housing 100 for installing the main control module 200. The main control module 200 includes a flexible circuit board 210, a capacitive wear detection circuit board 220, and a touch circuit board 230, wherein the capacitive wear detection circuit board 220 and the touch circuit board 230 are respectively electrically connected to the flexible circuit board 210.

[0026] As will be understood, the basic principle of a capacitive sensor is that it emits a low-frequency alternating electric field through electrodes. When a human body (a conductive object) approaches, the electric field distribution is altered, causing the capacitance between the electrode and ground (or another electrode) to increase. When not worn, the electric field is freely distributed in the air, resulting in a small and stable capacitance. When worn, human tissue absorbs the electric field, significantly increasing the capacitance by several to dozens of times. Thus, when a head-mounted display device with temple assemblies is worn and the head-mounted display device begins operation, a capacitor is formed between the capacitive wear detection circuit board 220 and the human head or ear facing it. Utilizing the principle of capacitors, the wearing status of the temple assemblies is monitored in real time, and the capacitance value or the change in capacitance value within a counting time is detected, thereby achieving real-time monitoring of the wearing status of the temple assemblies and the wearing status of the head-mounted display device. In this way, monitoring the wearing status of the temple assemblies through the capacitive wear detection circuit board 220 improves the accuracy of detecting the wearing status of the temple assemblies compared to the prior art configuration of proximity sensors. The counting time can be set according to the specific situation and is not limited here.

[0027] In one embodiment, the main control module 200 further includes a controller electrically connected to the flexible circuit board 210. The controller is also electrically connected to the capacitive wear detection circuit board 220 and the touch circuit board 230 via the flexible circuit board 210. The controller is configured to perform calculations and judgments on the detection results of the capacitor formed between the capacitive wear detection circuit board 220 and the human head or ear. In one embodiment, a method for detecting the wearing state of the temple assembly includes the following steps: First, real-time acquisition of the original measurement value C0 of the capacitive wear detection circuit board 220. Second, calculation of the capacitance change ΔC, where ΔC = C0 - Cbase, where Cbase is a dynamically updated ambient capacitance baseline and can be calculated using a first-order low-pass filtered differential equation. Third, determination of the wearing state is performed. If ΔC continuously exceeds a first threshold value T1 for N sampling periods, the initial wearing state is determined. That is, if ΔC continuously exceeds the first threshold value T1 N times within the counting time, the initial wearing state is determined. After the initial wearing state, if ΔC continuously exceeds a second threshold value T2, the wear state is determined to be sustained. That is, if ΔC remains above the second threshold value T2 during the counting time, the wear state is determined to be continuous. If ΔC remains below the third threshold value T3 for M consecutive sampling periods, the wear state is determined to be canceled. That is, if ΔC remains below the third threshold value T3 M times during the counting time, the wear state is determined to be canceled. This allows for detection of the temple assembly's wear state.

[0028] As will be appreciated, the differential equation for the first-order low-pass filter is prior art and will not be described in detail here. The first threshold T1, second threshold T2, third threshold T3, N sampling periods, M sampling periods, counting time, etc. can all be set according to actual circumstances and are not limited here. As will be appreciated, the method for detecting the wearing status is prior art and will not be described here in detail.

[0029] At the same time, the main control module 200 also includes a touch circuit board 230, which is electrically connected to the controller. The controller is used to receive touch signals detected by the touch circuit board 230 and control the operation of different components based on the touch signals. It can be understood that the housing 100 is configured as a touch area at a position corresponding to the touch circuit board 230. When using the temple assembly, the user can operate the head-mounted display device by touching, sliding, clicking, etc. in the touch area, such as adjusting the volume, playing music, switching pictures, etc. In this way, the ease of operation of the temple assembly is improved, and the functionality of the temple assembly is improved.

[0030] In one embodiment, when assembling the temple assembly, the flexible circuit board 210, the capacitive wear detection circuit board 220, and the touch circuit board 230 are first integrated into the main control module 200, and then the entire main control module 200 is installed in the housing 100. In this way, modular installation of the temple assembly is achieved, the temple assembly installation process is simplified, and the assembly efficiency of the temple assembly is improved.

[0031] The technical solution of the present invention is to set a housing 100 and a main control module 200 in the temple assembly, the main control module 200 being installed in the housing 100, the main control module 200 including a flexible circuit board 210, and a capacitive wearing detection circuit board 220 and a touch circuit board 230 electrically connected to the flexible circuit board 210, the capacitive wearing detection circuit board 220 being used to monitor the wearing state of the temple assembly, and the touch circuit board 230 being used to receive touch commands. Thus, on the one hand, compared with the prior art arrangement of monitoring the wearing state of the temple assembly by setting a proximity sensor, the present invention achieves monitoring of the wearing state of the temple assembly by setting a capacitive wearing detection circuit board 220 in the temple assembly, thereby improving the monitoring accuracy of the wearing state of the head-mounted display device and ensuring the use effect of the head-mounted display device. On the other hand, the touch circuit board 230 is set in the temple assembly, so that the head-mounted display device can be operated by touching the temple assembly, thereby improving the convenience of use of the head-mounted display device.

[0032] See also Figures 1 to 5In an embodiment of the present invention, the housing 100 includes a main body 111 and a tail end 112 connected to each other. The main body 111 is used to connect to the frame, and the tail end 112 is used to overlap the ear. The housing 100 includes a first shell 121 and a second shell 122 arranged opposite to each other. When worn, the first shell 121 is located on the side of the second shell 122 facing the head. The capacitive wearing detection circuit board 220 includes a first circuit board 221 , which is attached to the first shell 121 and located in the main body 111 ; and / or The capacitive wearing detection circuit board 220 includes a second circuit board 222 , which is attached to the second shell 122 and located at one end of the main body 111 toward the tail end 112 ; and / or The capacitive wearing detection circuit board 220 includes a third circuit board 223 . The third circuit board 223 is sandwiched between the first shell 121 and the second shell 122 and is located at the tail end portion 112 .

[0033] See also Figure 1 As can be understood, the temple assembly includes a left temple and a right temple, and the left temple and the right temple overlap with the left ear and the right ear respectively. The shell 100 has a certain length and thickness, and the length direction is roughly consistent with the front-to-back direction of the line of sight after the head-mounted display device is worn, and the thickness direction is the left-to-right direction from the left temple to the right temple. Along the length direction of the shell 100, the shell 100 includes a main body 111 and a tail end 112 connected to each other, wherein the main body 111 is used to connect to the frame of the head-mounted display device, and the tail end 112 is used to overlap with the ear. As can be understood, the main body 111 is consistent with the front-to-back direction of the line of sight after the head-mounted display device is worn. In one embodiment, the tail end 112 of the left temple and the tail end 112 of the right temple are respectively arranged close to each other, so as to improve the overlap tightness of the temple assembly and the ear.

[0034] In one embodiment, the housing 100 is configured as an integrally molded structure, with the end of the main body 111 distal from the tail end 112 having a receiving opening that communicates with the receiving cavity. The housing 100 is directly molded into the overall shape of the temple using injection molding, die casting, or expansion molding processes. This provides advantages such as an aesthetically pleasing, continuous appearance, the absence of seams or adhesive seams, and a large area for efficient heat dissipation. Compared to prior art methods that employ the splicing of left and right housings 100, the housing 100 of the present invention has a more streamlined design.

[0035] See also Figure 1 Along the thickness direction of the housing 100, that is, along the left-right direction of the temple assembly, the housing 100 includes a first shell 121 and a second shell 122 that are arranged opposite each other. When the head-mounted display device is worn, the first shell 121 is located on the side of the second shell 122 facing the head. In other words, when the head-mounted display device is worn, at least a portion of the first shell 121 will contact the head or ear.

[0036] See also Figure 2 and Figure 3 In one embodiment, the capacitive wear detection circuit board 220 includes a first circuit board 221. Specifically, the first circuit board 221 is attached to the inner wall of the first shell 121, and the first circuit board 221 is located in the main body 111. In this way, when the head-mounted display device is worn, the main body 111 of the first shell 121 is positioned relative to the head. It can be understood that according to the calculation formula of capacitance C (C=ɛS / d, where ɛ is the dielectric constant of the medium between the plates, S is the area covered between the plates, and d is the distance between the plates), the size of the capacitance is proportional to the area covered between the plates and inversely proportional to the distance between the plates. In this way, the closer the distance between the first circuit board 221 and the head, the larger the area projected by the first circuit board 221 on the head, the greater the detected capacitance value or the change in capacitance value during the counting time, that is, the more accurate the detection of the wearing status.

[0037] It is understood that when the head-mounted display device is worn, the end of the main body 111 facing the tail end 112 can be closer to the head. Therefore, to improve the accuracy of detecting the wearing status of the head-mounted display device, the first circuit board 221 is located at a position on the main body 111 near the tail end 112. It is understood that in the inward and outward directions, when the device is worn by a user with a larger head circumference, the gap between the temples and the face is smaller, that is, the distance between the first circuit board 221 and the head is smaller. When the device is worn by a user with a smaller head circumference, the gap between the temples and the face is larger, that is, the distance between the first circuit board 221 and the head is larger. In this way, when the head-mounted display device is worn by a user with a larger head circumference, the first circuit board 221 can more accurately detect the wearing status of the head-mounted display device.

[0038] See also Figure 2 and Figure 4In one embodiment, the capacitive wearing detection circuit board 220 includes a second circuit board 222. Specifically, the second circuit board 222 is attached to the inner wall of the second shell 122. In this way, when the head-mounted display device is worn, the second circuit board 222 is arranged opposite the ear. It can be understood that the closer the distance between the second circuit board 222 and the ear, the larger the area of the second circuit board 222 projected onto the ear, the greater the capacitance value detected or the change in capacitance value within the counting time, that is, the more accurate the wearing status detection of the head-mounted display device. It can be understood that when users with different head circumferences wear the same head-mounted display device, the relative distance between the main body 111 and the ear is different. When worn by a user with a larger head circumference, the main body 111 as a whole may be located in front of the ear. When worn by a user with a smaller head circumference, the end of the main body 111 facing the tail end 112 may be located above or behind the ear. Thus, positioning the second circuit board 222 at the end of the main body 111 facing the tail end 112, that is, placing the second circuit board 222 as close to the ear as possible, helps improve the accuracy of detecting the wearing state of the head-mounted display device. This allows the second circuit board 222 to more accurately detect the wearing state of the head-mounted display device when worn by a user with a smaller head circumference.

[0039] See also Figure 2 and Figure 5 In one embodiment, the capacitive wear detection circuit board 220 includes a third circuit board 223. Specifically, the third circuit board 223 is sandwiched between the first shell 121 and the second shell 122 and is located at the tail end portion 112. In one embodiment, the tail end portion 112 is solid at least in the portion near the main body 111, that is, the accommodating cavity is formed in the main body 111, and the third circuit board 223 is sandwiched between the first shell 121 and the second shell 122 of the tail end portion 112. In one embodiment, the housing 100 is configured as a plastic material. When injection molding is used, the third circuit board 223 can be sandwiched between the first shell 121 and the second shell 122 by insert injection molding. It can be understood that whether the user has a large head circumference or a small head circumference, the tail end portion 112 of the housing 100 can be well in contact with the head when wearing the head-mounted display device. In this way, it can ensure that a stable and large capacitance value or a change in capacitance value within the counting time is obtained when the temple assembly is worn.

[0040] Understandably, the capacitance sensor's detection limit distance is typically less than 5mm. For head-mounted display devices, different head shapes will have different contact points with the product. Improper design of the capacitive sensor's electrode placement may result in the product being able to detect on some head shapes but having difficulty detecting on others.

[0041] In one embodiment, the capacitive wear detection circuit board 220 includes any two or three of the first circuit board 221, the second circuit board 222, and the third circuit board 223, which is conducive to further improving the detection accuracy of the capacitance value or the change value of the capacitance value during the counting time. It is understandable that when the capacitive wear detection circuit board 220 includes multiple circuit boards, the capacitance value detected or the change value of the capacitance value during the counting time is the sum of the detection values of multiple circuit boards. The specific algorithm is not limited here. Take the capacitive wear detection circuit board 220 as an example, including the first circuit board 221 and the second circuit board 222. It is understandable that the first circuit board 221 is provided in the first shell 121 and is located at the main body 111, and the second circuit board 222 is provided in the second shell 122 and is located at one end of the main body 111 facing the tail end 112. Among them, the first circuit board 221 has a more accurate detection result for users with a larger head circumference, and the second circuit board 222 has a more accurate detection result for users with a smaller head circumference. In this way, by combining the capacitance values detected by the first circuit board 221 and the second circuit board 222, or the capacitance value change during the counting time, the head-mounted display device can obtain a relatively stable capacitance value or capacitance value change during the counting time for users with different head shapes, thereby ensuring the accuracy of wearing status detection. Thus, by rationally arranging the position of the capacitive wear detection circuit board 220, it can be well adapted to different head shapes, thereby expanding the applicability of the head-mounted display device.

[0042] See also Figure 5 In an embodiment of the present invention, when the capacitive wear detection circuit board 220 includes a third circuit board 223, an end of the flexible circuit board 210 facing the tail end portion 112 is connected to an elastic electrical contact 211, and an end of the elastic electrical contact 211 away from the flexible circuit board 210 is used to be electrically connected to the third circuit board 223.

[0043] As will be appreciated, when a third circuit board 223 is provided in the temple assembly, to ensure electrical connection between the third circuit board 223 and the flexible circuit board 210, that is, to achieve electrical connection between the third circuit board 223 and the controller, in the embodiment shown in the figures of the present invention, the flexible circuit board 210 extends within the main body 111. A resilient electrical contact 211 is connected to the end of the flexible circuit board 210 proximate the tail end 112. The end of the resilient electrical contact 211 distal from the flexible circuit board 210 is used for electrical connection to the third circuit board 223. The provision of the resilient electrical contact 211 ensures electrical connection between the flexible circuit board 210 and the third circuit board 223. Furthermore, compared to a non-resilient arrangement, the resilient arrangement of the resilient electrical contact 211 ensures a reliable electrical connection between the flexible circuit board 210 and the third circuit board 223. In one embodiment, the resilient electrical connector is configured as a Pogo pin. Alternatively, the resilient electrical connector may be a spring clip, a plug pin, or other resilient electrical connection structures.

[0044] See also Figure 1 In an embodiment of the present invention, when the capacitive wear detection circuit board 220 includes a second circuit board 222 , a boss 131 is formed on the lower side of the main body 111 at one end facing the tail end 112 , and the second circuit board 222 is attached to the boss 131 .

[0045] It will be appreciated that when the capacitive wear detection circuit board 220 includes a second circuit board 222, the second circuit board 222 is disposed within the second shell 122. In the embodiment illustrated in the figures of the present invention, a boss 131 is formed on the underside of the main body 111, facing the tail end 112. The second circuit board 222 is attached to the boss 131, that is, the second circuit board 222 is disposed on the inner wall of the underside of the second shell 122. In one embodiment, to ensure the installation stability of the second circuit board 222, the second circuit board 222 is attached to the temple bracket 240, corresponding to the location of the boss 131. In other words, the second circuit board 222 is sandwiched between the temple bracket 240 and the inner wall of the underside of the second shell 122, with the temple bracket 240 providing support for the second circuit board 222. A description of the temple bracket 240 is provided below. This allows the second circuit board 222 to extend not only along the length of the temple assembly but also along its thickness. In this way, compared with attaching the second circuit board 222 to the inner wall of the outer side of the second shell 122, that is, the second circuit board 222 extends along the length direction of the temple assembly while also extending along the upper and lower directions of the temple assembly, the present invention enables the second circuit board 222 to be projected onto the ear with a larger area, which is beneficial to the accuracy of detecting the capacitance value or the change in capacitance value within the counting time, and is beneficial to the accuracy of detecting the wearing status.

[0046] See also Figure 2 In an embodiment of the present invention, when the capacitive wearing detection circuit board 220 includes a first circuit board 221 and a second circuit board 222, the first circuit board 221, the second circuit board 222 and the flexible circuit board 210 are integrated or separated.

[0047] In one embodiment, the capacitive wearing detection circuit board 220 includes a first circuit board 221 and a second circuit board 222. In one embodiment, the first circuit board 221 and the second circuit board 222 and the flexible circuit board 210 are integrated. This is conducive to the integration of the structure, facilitates the assembly of the main control module 200, and facilitates the assembly of the temple assembly.

[0048] Furthermore, in one embodiment, the first circuit board 221, the second circuit board 222, the flexible circuit board 210 and the touch circuit board 230 are integrated, which is further conducive to the integration of the structure, further facilitates the assembly of the main control module 200, and facilitates the assembly of the temple assembly.

[0049] Of course, in other embodiments, the first circuit board 221, the second circuit board 222, the flexible circuit board 210, and the touch circuit board 230 are provided separately. In this way, the electrical connection between the flexible circuit board 210 and other circuit boards can also be achieved.

[0050] See also Figure 1 、 Figure 2 and Figure 6 In an embodiment of the present invention, the housing 100 includes a first shell 121 and a second shell 122 that are arranged opposite to each other. When worn, the first shell 121 is located on the side of the second shell 122 facing the head. The touch circuit board 230 is attached to the second shell 122 . The main control module 200 further includes a temple bracket 240 . The touch circuit board 230 is installed on a side of the temple bracket 240 facing the second shell 122 .

[0051] As can be appreciated, attaching the touch circuit board 230 to the inner wall of the second shell 122 allows the user to directly perform touch operations on the outside of the temple assembly housing 100. This arrangement improves the ease of use of the temple assembly compared to attaching the touch circuit board 230 to the inner wall of the first shell 121. In one embodiment, to improve the ease of use of the touch area, the touch circuit board 230 is disposed on the main body 111.

[0052] See also Figure 7 and Figure 8 In the embodiment shown in the drawings of the present invention, the main control module 200 further includes a temple bracket 240. The touch circuit board 230 is mounted on the temple bracket 240 and is located on the side of the temple bracket 240 facing the second shell 122. In this way, the touch circuit board 230 is attached to the inner wall of the second shell 122. The temple bracket 240 provides support for the installation of the touch circuit board 230, so that the touch circuit board 230 abuts against the inner wall of the second shell 122.

[0053] See also Figure 2 In one embodiment, the main control module 200 also includes structures such as a speaker 272 and a hinge 271. During assembly, the speaker 272, the hinge 271 and other structures are pre-installed on the temple bracket 240 to form the main control module 200, and then the main control module 200 is installed in the shell 100. This makes the installation of the temple assembly modular, which is conducive to improving the assembly efficiency of the temple assembly.

[0054] See also Figure 2 In an embodiment of the present invention, the main control module 200 further includes a battery 250 mounted on the temple bracket 240 , and an elastic member 251 is provided between the battery 250 and the touch circuit board 230 .

[0055] As will be appreciated, in one embodiment, the main control module 200 further includes a battery 250, which is used to provide power to the various circuit boards, chips, and the like within the main control module 200. The battery 250 is mounted on the temple bracket 240. In one embodiment, the battery 250 is positioned between the temple bracket 240 and the touch circuit board 230. An elastic member 251 is positioned between the battery 250 and the touch circuit board 230. The elastic member 251 compresses the touch circuit board 230 against the inner wall of the second shell 122. The provision of the elastic member 251 ensures stable contact between the touch circuit board 230 and the second shell 122. In one embodiment, the elastic member 251 is configured as foam. Of course, in other embodiments, the elastic member 251 can also be other elastomers, such as silicone or thermal pads.

[0056] See also Figure 8 In an embodiment of the present invention, the main control module 200 also includes a main board 260 installed on the temple bracket 240 and a main chip 261 provided on the main board 260. The main board 260 is located on the side of the temple bracket 240 facing the first shell 121, and the main chip 261 is provided on the side facing the second shell 122.

[0057] As will be understood, the temple assembly includes a left temple and a right temple. Generally, the battery 250 is located in one of the left or right temples, and the mainboard 260 is located in the other. This allows for efficient use of the space within the housing 100 and facilitates the installation of components. In the embodiment shown in the figures of the present invention, in one embodiment, the main control module 200 includes a mainboard 260. The mainboard 260 is mounted on the temple support 240. In one embodiment, the mainboard 260 is located on the side of the temple support 240 facing the first housing 121, i.e., the mainboard 260 is located on the inner side of the temple support 240. In one embodiment, the mainboard 260 is secured to the temple support 240 using screws or snaps. The mainboard 260 also includes a main chip 261, which serves as one of the main heat sources of the main control module 200. The main chip 261 is located on one side of the second housing 122, i.e., it is located on the outer side of the temple assembly. This can prevent the inner side of the temple assembly, which is close to the head, from becoming too hot and causing discomfort when wearing it.

[0058] See also Figure 8 In an embodiment of the present invention, the temple bracket 240 is provided with a first temperature balancing member 263 at a position corresponding to the main board 260 on the side facing the main board 260 .

[0059] It is understandable that when the main control module 200 is working, the main board 260 generates heat, and the main chip 261 thereon generates a relatively high amount of heat. When the heat diffuses toward the second shell 122, in order to ensure the heat dissipation effect, the temple bracket 240 is provided with a first temperature-averaging member 263 on the side facing the main board 260, at a position corresponding to the main board 260. The first temperature-averaging member 263 can evenly distribute the heat transferred from the main board 260 and the main chip 261 along the length direction of the shell 100, and is also conducive to quickly dissipating the heat and avoiding heat accumulation. In one embodiment, the first temperature-averaging member 263 is configured as a graphite sheet. Of course, in other embodiments, the first temperature-averaging member 263 can also be a temperature-averaging material such as copper foil, aluminum foil, or graphene film.

[0060] See also Figure 8 In an embodiment of the present invention, a thermal interface material 262 is provided between the first temperature-balancing member 263 and the main chip 261 .

[0061] As you can understand, thermal interface material 262 is used to fill the tiny gap between two contacting surfaces to improve heat transfer efficiency. Its core function is to reduce interfacial thermal resistance and enhance heat dissipation performance. First temperature balancing member 263 is positioned opposite main chip 261. To reduce thermal resistance, thermal interface material 262 is positioned between first temperature balancing member 263 and main chip 261. Opposite sides of thermal interface material 262 contact first temperature balancing member 263 and main chip 261, respectively. Thermal interface material 262 can be thermal grease, thermal gel, thermal pads, etc.

[0062] In this embodiment of the present invention, a second temperature-balancing member (not shown) is positioned between the main chip 261 and the thermal interface material 262. This allows the main chip 261 to first be heated by the second temperature-balancing member, and then transfer the heat to the first temperature-balancing member 263 through the thermal interface material 262. This improves the heat dissipation of the temple assembly. The second temperature-balancing member can be a heat pipe, VC, graphite sheet, or other thermally conductive material.

[0063] See also Figure 8 In an embodiment of the present invention, an elastic heat conductive member 264 is provided between the temple bracket 240 and the touch circuit board 230 , and the elastic heat conductive member 264 is used to abut the touch circuit board 230 against the inner wall of the second shell 122 .

[0064] It is understood that in the direction from the first shell 121 to the second shell 122, that is, from the inside to the outside, the main board 260, the main chip 261, the thermal interface material 262, the first temperature-averaging member 263, the temple bracket 240, the touch circuit board 230, and the second shell 122 are arranged in this order. Heat from the main board 260 and the main chip 261 is transferred to the temple bracket 240 through the thermal interface material 262 and the first temperature-averaging member 263, and then transferred to the touch circuit board 230 through the temple bracket 240. To ensure effective heat transfer from the temple bracket 240 to the touch circuit board 230, an elastic thermal conductor 264 is provided between the temple bracket 240 and the touch circuit board 230. The provision of the elastic heat-conducting member 264, on the one hand, ensures that heat is effectively transferred from the temple support 240 to the touch circuit board 230, ensuring that most of the heat is transferred to the touch circuit board 230, and then to the second shell 122 for dissipation, thereby preventing a large amount of heat from accumulating in the accommodating cavity and thus preventing damage to the main control module 200 caused by high temperatures. On the other hand, the elastic heat-conducting member 264 itself has a certain degree of elasticity. During the assembly of the temple assembly, after the main control module 200 is interference-fitted into the housing 100, the elastic heat-conducting member 264 is subjected to a certain degree of compression. Under the action of its own elastic force, the elastic heat-conducting member 264 presses the touch circuit board 230 against the inner wall of the second shell 122, ensuring the contact stability between the touch circuit board 230 and the second shell 122.
