[0071] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0072] In the description of this application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the appendix.

[0073] It should be understood that "connection" and "connected" can both refer to a mechanical or physical connection. That is, A and B being connected or connected can mean that there are fastened components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0074] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0075] Augmented Reality (AR) technology is a technology that cleverly integrates virtual information with the real world. It widely uses various technologies such as multimedia, 3D modeling, real-time tracking and registration, intelligent interaction, and sensing to simulate and apply computer-generated virtual information such as text, images, 3D models, music, and videos to the real world. The two types of information complement each other, thereby achieving "enhancement" of the real world.

[0076] In related technologies, AR glasses typically require the configuration of electrical components such as circuit boards, optical engine modules, and cameras. During the AR glasses process, the circuit boards and optical engine modules generate a lot of heat, which can cause the local temperature of the AR glasses to rise. When users wear them, the corresponding skin will feel a noticeable burning sensation, resulting in significant discomfort.

[0077] Therefore, this application provides an AR glasses that utilizes the transaxial heat-conducting sheet to establish a heat transfer path between the temple module and the front frame module, enabling heat transfer between the temple module and the front frame module. This reduces local heat density and allows for heat dissipation from the surfaces of both the temple module and the front frame module, thereby improving the overall heat dissipation efficiency of the AR glasses.

[0078] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0079] Combination Figure 1 and Figure 2 As shown, this embodiment provides an AR glasses, which includes: a front frame module 1, a first temple module 2, and a second temple module 3.

[0080] The first temple module 2 and the second temple module 3 are rotatably connected to the front frame module 1, respectively; at least one of the first temple module 2 and the second temple module 3 is provided with a transaxial heat-conducting plate 4, one end of the transaxial heat-conducting plate 4 is located in the first temple module 2 or the second temple module 3, and the other end of the transaxial heat-conducting plate 4 is located in the front frame module 1.

[0081] In this embodiment of the AR glasses, one of the first temple module 2 and the second temple module 3 has a transaxial heat-conducting plate 4 between it and the front frame module 1. Using this transaxial heat-conducting plate 4, a heat transfer path can be established between the temple module and the front frame module 1, allowing heat transfer between them. When the heat generation of the temple module is large and the heat generation of the front frame module 1 is small, the transaxial heat-conducting plate 4 can transfer the heat from the temple module to the front frame module 1. When the heat generation of the temple module is small and the heat generation of the front frame module 1 is large, the transaxial heat-conducting plate 4 can transfer the heat from the front frame module 1 to the temple module. On the one hand, this reduces the heat density on the temple module and the front frame module 1, and on the other hand, it allows for heat dissipation using the surfaces of the temple module and the front frame module 1 simultaneously, improving the overall heat dissipation efficiency of the AR glasses.

[0082] In some possible implementations, the first temple module 2 is provided with a transaxial heat-conducting plate 4, one end of which is located inside the first temple module 2 and the other end is located inside the front frame module 1. A heat transfer path can be established between the first temple module 2 and the front frame module 1, so that heat can be transferred between the first temple module 2 and the front frame module 1.

[0083] In some possible implementations, the second temple module 3 is provided with a transaxial heat-conducting plate 4, one end of which is located inside the second temple module 3 and the other end is located inside the front frame module 1. A heat transfer path can be established between the second temple module 3 and the front frame module 1, so that heat can be transferred between the second temple module 3 and the front frame module 1.

[0084] In some other possible implementations, the first temple module 2 and the second temple module 3 are respectively provided with transaxial heat-conducting plates 4. One end of one transaxial heat-conducting plate 4 is located inside the first temple module 2 and the other end is located inside the front frame module 1, which can establish a heat transfer path between the first temple module 2 and the front frame module 1, so that the first temple module 2 and the front frame module 1 can transfer heat. The other transaxial heat-conducting plate 4 is located inside the second temple module 3 and the other end is located inside the front frame module 1, which can establish a heat transfer path between the second temple module 3 and the front frame module 1, so that the second temple module 3 and the front frame module 1 can transfer heat.

[0085] Optionally, the transaxial heat-conducting sheet 4 can be a unidirectional heat-conducting sheet, allowing heat to be transferred only from a specific end to the other end, or the heat conduction efficiency from a specific end to the other end is greater than the heat conduction efficiency in the reverse direction. For example, it can be a unidirectional heat-conducting sheet of the first temple module 2 or the second temple module 3 toward the front frame module 1, or a unidirectional heat-conducting sheet of the front frame module 1 toward the first temple module 2 or the second temple module 3.

[0086] Alternatively, the transaxial heat-conducting sheet 4 can also be a bidirectional heat-conducting sheet. The transaxial heat-conducting sheet 4 can transfer heat from the higher-temperature components to the lower-temperature components based on the temperature difference between the first temple module 2, the second temple module 3, and the front frame module 1.

[0087] Combination Figure 2 and Figure 3 As shown, in some embodiments, the transaxial heat-conducting sheet 4 includes a first portion 401, a wavy portion 402, and a second portion 403 connected in sequence; the first portion 401 is located in the first temple module 2 or the second temple module 3, the second portion 403 is located in the front frame module 1, and the wavy portion 402 is located in the first connection area 01 corresponding to the first temple module 2 and the front frame module 1, or the second connection area 02 corresponding to the second temple module 3 and the front frame module 1.

[0088] Based on the above arrangement, the transaxial heat-conducting sheet 4 is designed with a three-section structure according to the connection scenario between the first temple module 2 or the second temple module 3 and the front frame module 1. The first part 401 is arranged in the corresponding first temple module 2 or second temple module 3, which can absorb heat from the temple module or transfer heat to the temple module. The second part 403 is arranged in the front frame module 1, which can absorb heat from the front frame module 1 or transfer heat to the front frame module 1. The wavy part 402 is arranged in the first connection area 01 and / or the second connection area 02, which can realize the heat transfer between the first part 401 and the second part 403 in the special structure of the first connection area 01 or the second connection area 02.

[0089] For example, the first connecting region 01 and the second connecting region 02 can be used for the rotational connection of the first temple module 2 and the second temple module 3 with the front frame module 1, respectively, to realize the folding and storage of the first temple module 2 and the second temple module 3. When the first temple module 2 or the second temple module 3 is rotated and folded, the transaxial heat-conducting sheet 4 will be rotated and folded synchronously. Since the transaxial heat-conducting sheet 4 is usually not elastic, when the first part 401 and the second part 403 are fixedly connected at the same time, the transaxial heat-conducting sheet 4 will be stretched or compressed, resulting in stress damage. Therefore, in this embodiment, the part of the transaxial heat-conducting sheet 4 located in the first connecting region 01 and the second connecting region 02 is designed to be wavy. When the transaxial heat-conducting sheet 4 is subjected to tension or pressure, the wavelength of the wavy part 402 can be changed to change the total length of the wavy part 402, adapting to the connection length between the first part 401 and the second part 403, preventing stress damage to the transaxial heat-conducting sheet 4, and extending the service life of the transaxial heat-conducting sheet 4.

[0090] In some possible implementations, the wavy portion 402 is a polygonal wave, its waveform composed of straight line segments, resembling a broken line. A polygonal wave is characterized by its non-smooth waveform with abrupt changes at inflection points. It can be periodic or non-periodic. The wavy portion 402, designed with a polygonal wave, has fixed creases. When the wavy portion 402 is stretched or compressed, it can be stretched or folded relatively smoothly along these fixed creases.

[0091] For example, the angle of the crest or trough in the wavy section 402 in the initial state ranges from 120° to 140°. Optionally, the angle of the crest or trough in the initial state is 130°.

[0092] Combination Figure 3 As shown, in some embodiments, the number of transaxial heat-conducting plates 4 is at least two; the at least two transaxial heat-conducting plates 4 are located on the inner and outer sides of the first connection region 01, or on the inner and outer sides of the second connection region 02, respectively.

[0093] With the above arrangement, by arranging transaxial heat-conducting plates 4 on the inner and outer sides of the first connection area 01 and / or the second connection area 02 respectively, each temple module can be connected to the front frame module 1 through two transaxial heat-conducting plates 4 respectively, which can obtain a larger heat transfer path, improve the heat transfer efficiency of the temple module and the front frame module 1, and thus improve the heat dissipation efficiency of the AR glasses.

[0094] Combination Figure 3As shown, in some embodiments, the transaxial heat-conducting sheet 4 includes at least two graphite layers 404 and at least one connecting layer 405, with the at least two graphite layers 404 stacked together and a connecting layer 405 provided between two adjacent graphite layers 404.

[0095] In this embodiment, the transaxial heat-conducting sheet 4 has multiple stacked graphite layers 404, which can utilize the high thermal conductivity of graphite material to improve the thermal conductivity of the transaxial heat-conducting sheet 4. In order to prevent delamination between graphite layers 404, a connecting layer 405 is used to connect two adjacent graphite layers 404.

[0096] For example, the graphite layer 404 is made of graphite material. Compared with other materials, graphite is a novel thermally conductive and heat-dissipating material. Its main component is carbon, and it is an allotrope of carbon with unique grain orientation and lamellar structure, enabling it to conduct heat uniformly in two directions. In this embodiment, the graphite layer 404 has many advantages such as high thermal conductivity, low thermal resistance, light weight, good flexibility and processability, chemical stability, and high temperature resistance.

[0097] In some possible implementations, the number of graphite layers 404 can be two, three, four, etc., and this application does not limit this.

[0098] In this embodiment, the portion of the transaxial heat-conducting sheet 4 corresponding to the first connection region 01 or the second connection region 02 is a wavy portion 402. The wavy design can effectively prevent the graphite sheets in the corresponding connection region from cracking and delaminating due to interlayer stress differences, thereby improving the structural stability and operational reliability of the transaxial heat-conducting sheet 4.

[0099] Combination Figure 3 As shown, in some embodiments, the transaxial heat-conducting sheet 4 further includes two thermoplastic layers 406, which are located on two surfaces of the transaxial heat-conducting sheet 4 respectively.

[0100] With the above arrangement, the two surfaces of the transaxial heat-conducting sheet 4 can be protected by the thermoplastic layer 406 respectively.

[0101] For example, refer to Figure 3 As shown, the transaxial heat-conducting sheet 4 includes a thermoplastic layer 406, a graphite layer 404, a connecting layer 405, a graphite layer 404, and a thermoplastic layer 406 arranged in sequence.

[0102] Combination Figure 5 As shown, in some embodiments, at least one of the front frame module 1, the first temple module 2, and the second temple module 3 is provided with at least one heat sink 5, and at least one of the heat sinks 5 is thermally connected to the transaxial heat-conducting sheet 4.

[0103] To further improve the heat dissipation efficiency of the front frame module 1, the first temple module 2, and the second temple module 3, at least one heat sink 5 can be arranged in each of the front frame module 1, the first temple module 2, and the second temple module 3, and the heat sink 5 can be thermally connected to the transaxial heat-conducting plate 4. The heat sink 5 can quickly dissipate the heat in the transaxial heat-conducting plate 4 to the outside, thereby improving the heat dissipation efficiency of the front frame module 1, the first temple module 2, and the second temple module 3.

[0104] In some possible implementations, the front frame module 1 is provided with at least one heat sink 5, which is thermally connected to a transaxial heat-conducting sheet 4 extending into the front frame module 1. Optionally, the number of heat sinks 5 in the front frame module 1 may be, for example, one, two, three, etc., and multiple heat sinks 5 may be thermally connected to the transaxial heat-conducting sheet 4 individually, or one or a portion thereof may be thermally connected to the transaxial heat-conducting sheet 4.

[0105] In some possible implementations, the first temple module 2 is provided with at least one heat sink 5, which is thermally connected to a transaxial heat-conducting sheet 4 extending into the first temple module 2. Optionally, the number of heat sinks 5 in the first temple module 2 may be, for example, one, two, three, etc., and multiple heat sinks 5 may be thermally connected to the transaxial heat-conducting sheet 4 individually, or one or a portion thereof may be thermally connected to the transaxial heat-conducting sheet 4.

[0106] In some possible implementations, the second temple module 3 is provided with at least one heat sink 5, which is thermally connected to a transaxial heat-conducting sheet 4 extending into the second temple module 3. Optionally, the number of heat sinks 5 in the second temple module 3 may be, for example, one, two, three, etc., and multiple heat sinks 5 may be thermally connected to the transaxial heat-conducting sheet 4 individually, or one or a portion thereof may be thermally connected to the transaxial heat-conducting sheet 4.

[0107] Combination Figure 6 As shown, in some embodiments, at least one of the front frame module 1, the first temple module 2, and the second temple module 3 is provided with a receiving cavity 6. At least one heat sink 5 is attached to the inner wall of the receiving cavity 6, and the heat sink 5 is thermally connected to the transaxial heat-conducting plate 4.

[0108] In this embodiment, heat sinks 5 are provided on the inner wall of the receiving cavity 6 in the front frame module 1, the first temple module 2, and the second temple module 3. The receiving cavity 6 is usually surrounded by the shell of the front frame module 1, the first temple module 2, or the second temple module 3. The heat sinks 5 are attached to its inner wall, and the heat sinks 5 can be used to directly transfer the heat of the transaxial heat conduction plate 4 to the shell. The shell is in contact with the outside air, so the heat can be dissipated more quickly.

[0109] Combination Figure 7 and Figure 8As shown, in some embodiments, the transaxial heat-conducting sheet 4 includes a first transaxial heat-conducting sheet 41, which is located inside the first temple module 2. The first temple module 2 also includes a mainboard module 21.

[0110] The receiving cavity 6 includes a first receiving cavity 61 located within the first temple module 2. The first receiving cavity 61 includes a first outer inner wall 611 away from the human body. The heat sink 5 includes a first heat sink 51 attached to the first outer inner wall 611.

[0111] One end of the first transaxial heat-conducting plate 41 and the motherboard module 21 are respectively located in the first receiving cavity 61, and one end of the first transaxial heat-conducting plate 41 is located between the motherboard module 21 and the first heat sink 51, and makes thermal contact with the motherboard module 21 and the first heat sink 51 respectively.

[0112] With the above arrangement, the first temple module 2 has a main board module 21 that generates a large amount of heat. Part of the heat generated by the main board module 21 is transferred to the front frame module 1 through the first transaxial heat conduction plate 41 and dissipated outward through the outer surface of the front frame module 1. The other part is transferred to the first outer inner wall 611, which is away from the human body, through the first transaxial heat conduction plate 41 and the first heat sink 51. The first outer inner wall 611 corresponds to the shell of the first temple module 2 that is away from the human body, and can then dissipate outward through the shell that is away from the human body. Since it is far from the human body, the user will not feel uncomfortable and has better wearing comfort.

[0113] Among some possible implementations, refer to Figure 7 and Figure 8 As shown, the first temple module 2 includes a first outer shell 23 and a first inner shell 24 fastened together. The first receiving cavity 61 is located between the first outer shell 23 and the first inner shell 24. The first outer inner wall 611 is located on the side of the first outer shell 23 facing the first inner shell 24, and the first inner inner wall 612 is located on the side of the first inner shell 24 facing the first outer shell 23.

[0114] Combination Figure 7 and Figure 8 As shown, in some embodiments, the first receiving cavity 61 further includes a first inner wall 612 close to the human body, and the heat sink 5 includes a second heat sink 52; the second heat sink 52 is attached to the first inner wall 612, and the second heat sink 52 is located between the motherboard module 21 and the first inner wall 612.

[0115] To further improve user comfort, a second heat sink 52 is arranged between the motherboard module and the first inner wall 612 closest to the human body. The second heat sink 52 can quickly and evenly dissipate the heat that inevitably radiates towards the human body, preventing local heat accumulation on the first inner wall 612 and temperature rise, which could cause a burning sensation to the user.

[0116] Combination Figure 7 and Figure 8 As shown, in some embodiments, the first temple module 2 further includes a first heat insulation sheet 22, which is located between the main board module 21 and the first inner wall 612.

[0117] With the above arrangement, a first heat insulation sheet 22 is arranged between the motherboard module and the first inner wall 612 close to the human body. The first heat insulation sheet 22 can block the heat of the motherboard module 21 from being transferred to the first inner wall 612. Very little heat can be transferred to the shell that is close to the human body, which helps to further improve the user's wearing comfort.

[0118] Among some possible implementations, refer to Figure 7 and Figure 8 As shown, the first transaxial heat-conducting sheet 41 includes a first inner transaxial heat-conducting sheet 411 and a first outer transaxial heat-conducting sheet 412. The first inner transaxial heat-conducting sheet 411 is located inside the first connection area 01, and the first outer transaxial heat-conducting sheet 412 is located outside the first connection area 01.

[0119] Combination Figure 9 and Figure 10 As shown, in some embodiments, the transaxial heat-conducting sheet 4 includes a second transaxial heat-conducting sheet 42, which is located within the second temple module 3. The second temple module 3 also includes a battery module 31.

[0120] The receiving cavity 6 includes a second receiving cavity 62 located within the second temple module 3. The second receiving cavity 62 includes a second outer inner wall 621 away from the human body. The heat sink 5 includes a third heat sink 53 attached to the second outer inner wall 621.

[0121] One end of the second transaxial heat-conducting sheet 42 and the battery module 31 are respectively located in the second receiving cavity 62, and one end of the second transaxial heat-conducting sheet 42 is located between the battery module 31 and the third heat sink 53, and makes thermal contact with the battery module 31 and the third heat sink 53 respectively.

[0122] With the above arrangement, the second temple module 3 has a battery module 31 with less heat generation. Compared with the front frame module 1, the second temple module 3 generates less heat. Therefore, the heat in the front frame module 1 can be transferred to the second temple module 3 through the second transaxial heat-conducting plate 42. Moreover, this heat can be diffused and dissipated outward along the second outer inner wall 621 away from the human body through the third heat sink 53. Since it is far away from the human body, the user will not feel uncomfortable and has better wearing comfort.

[0123] Among some possible implementations, refer to Figure 9 and Figure 10As shown, the second receiving cavity 62 includes a second inner wall 622 close to the human body, and the battery module 31 is arranged close to the second inner wall 622.

[0124] Combination Figure 9 and Figure 10 As shown, in some embodiments, the second transaxial heat-conducting sheet 42 includes a second inner transaxial heat-conducting sheet 421 and a second outer transaxial heat-conducting sheet 422.

[0125] The second inner transaxial heat-conducting sheet 421 is disposed on the inner side of the second connection area 02 corresponding to the second temple module 3 and the front frame module 1, and the second outer transaxial heat-conducting sheet 422 is disposed on the outer side of the second connection area 02.

[0126] The second temple module 3 also includes a heat-conducting connecting piece 32; the heat-conducting connecting piece 32 is located in the second receiving cavity 62 and between the second inner transaxial heat-conducting piece 421 and the second outer transaxial heat-conducting piece 422, so as to make heat-conducting contact with the second inner transaxial heat-conducting piece 421 and the second outer transaxial heat-conducting piece 422 respectively.

[0127] In this embodiment, in order to improve the efficiency of heat transfer from the front frame module 1 to the second temple module 3, a second inner transaxial heat-conducting sheet 421 and a second outer transaxial heat-conducting sheet 422 are respectively arranged on the inner and outer sides of the second connection area 02. The two transaxial heat-conducting sheets 4 provide two heat dissipation paths for the front frame module 1, and the heat of the front frame module 1 can be quickly transferred to the second temple module 3, thereby preventing the temperature rise of the front frame module 1 from being too high.

[0128] Among some possible implementations, refer to Figure 9 and Figure 10 As shown, the second temple module 3 includes a second outer shell 33 and a second inner shell 34 fastened together. The second receiving cavity 62 is located between the second outer shell 33 and the second inner shell 34. The second outer inner wall 621 is located on the side of the second outer shell 33 facing the second inner shell 34, and the second inner inner wall 622 is located on the side of the second inner shell 34 facing the second outer shell 33.

[0129] Combination Figure 11 As shown, in some embodiments, the front frame module 1 includes a front shell 11, a rear shell 12, a frame heat-conducting sheet 13, a front shell heat-conducting sheet 14, and a rear shell heat-conducting sheet 15; the front shell 11 and the rear shell 12 are connected to each other.

[0130] The front shell 11 has a frame portion 111 corresponding to the connection of the first temple module 2 and the second temple module 3, and a lens portion 112 corresponding to the mounting of the lens 113; a frame heat-conducting sheet 13 is attached to the inner wall of the frame portion 111, and a front shell heat-conducting sheet 14 is attached to the inner wall of the lens portion 112; a rear shell heat-conducting sheet 15 is attached to the inner wall of the rear shell 12; one end of the transaxial heat-conducting sheet 4 extends between the front shell 11 and the rear shell 12, and makes thermal contact with at least one of the frame heat-conducting sheet 13, the front shell heat-conducting sheet 14 and the rear shell heat-conducting sheet 15.

[0131] With the above arrangement, the front frame module 1 is formed by the front shell 11 and the rear shell 12, which respectively have a frame heat-conducting sheet 13, a front shell heat-conducting sheet 14 and a rear shell heat-conducting sheet 15. The three heat-conducting sheets are respectively arranged on the inner wall of different parts of the front frame module 1. The transaxial heat-conducting sheet 4 can make thermal contact with at least one of the three heat-conducting sheets, so that the transaxial heat-conducting sheet 4 can absorb the heat in the front frame module 1 using the three heat-conducting sheets, and the latter transfers the heat to the front frame module 1 and dissipates it outward using the outer surface of the front frame module 1.

[0132] Combination Figure 12 As shown, in some embodiments, the front frame module 1 further includes an optical engine module 16, a camera module 17, an optical engine heat sink 18, and a camera heat sink 19.

[0133] The optical engine module 16 and the camera module 17 are located between the front shell 11 and the rear shell 12, respectively. The optical engine module 16 is in thermal contact with the transaxial heat-conducting plate 4 through the optical engine heat-conducting plate 18, and the camera module 17 is in thermal contact with the optical engine heat-conducting plate 18 through the camera heat-conducting plate 19.

[0134] In this embodiment, the optical engine module 16 and camera module 17 in the front frame module 1 can transfer heat to the transaxial heat conduction sheet 4 through the optical engine heat conduction sheet 18 and camera heat conduction sheet 19, respectively, and then transfer it to the first temple module 2 or the second temple module 3 through the transaxial heat conduction sheet 4, thereby preventing the heat from accumulating in the optical engine module 16 and camera module 17 and causing the temperature of the front frame module 1 to be too high.

[0135] Combination Figure 11 As shown, in some embodiments, the front frame module 1 further includes a second heat insulation sheet 110, which is located between the rear heat-conducting sheet 15 and the inner wall of the rear shell 12. Since the rear shell 12 is close to the user's eyes, this embodiment, by using the second heat insulation sheet 110 arranged between the rear heat-conducting sheet 15 and the rear shell 12, can prevent heat from the front frame module 1 from being transferred to the rear shell 12, causing an increase in the temperature of the rear shell 12 and causing eye discomfort to the user.

[0136] Combination Figure 11As shown, in some embodiments, when the transaxial heat-conducting sheet 4 includes a first transaxial heat-conducting sheet 41 and a second transaxial heat-conducting sheet 42; the first transaxial heat-conducting sheet 41 is in thermal contact with the frame heat-conducting sheet 13, the frame heat-conducting sheet 13 is in thermal contact with the front shell heat-conducting sheet 14, and the second transaxial heat-conducting sheet 42 is in thermal contact with the rear shell heat-conducting sheet 15.

[0137] In this embodiment, the frame heat-conducting sheet 13 and the back shell heat-conducting sheet 15 can respectively make thermal contact with the first transaxial heat-conducting sheet 41 and the second transaxial heat-conducting sheet 42, and the heat is transferred by the two transaxial heat-conducting sheets 4 arranged on the inner and outer sides of the connection area.

[0138] Combination Figure 12 As shown, in some embodiments, when the second transaxial heat-conducting sheet 42 includes a second inner transaxial heat-conducting sheet 421 and a second outer transaxial heat-conducting sheet 422, and the front frame module 1 includes a rear shell heat-conducting sheet 15 and an optomechanical heat-conducting sheet 18; the second inner transaxial heat-conducting sheet 421 is in thermal contact with the rear shell heat-conducting sheet 15, and the second outer transaxial heat-conducting sheet 422 is in thermal contact with the optomechanical heat-conducting sheet 18.

[0139] Considering that the rear shell heat-conducting sheet 15 and the rear shell 12 in the front frame module 1 are close to the user's eyes, the heat from the rear shell heat-conducting sheet 15 can be quickly transferred to the second temple module 3 by using the second inner transaxial heat-conducting sheet 421 to conduct heat with the rear shell heat-conducting sheet 15, thus preventing the rear shell 12 from overheating. The optical engine heat-conducting sheet 18 is used to absorb the large amount of heat released by the optical engine module 16. This heat can be quickly transferred to the second temple module 3 by using the second outer transaxial heat-conducting sheet 422, thus preventing the optical engine module 16 from overheating.

[0140] Among some possible implementations, refer to Figure 12 As shown, the camera module 17 and the optical engine module 16 are located close to each other. The camera heat-conducting plate 19 and the optical engine heat-conducting plate 18 are in thermal contact. The heat of the camera module 17 can be transferred to the optical engine heat-conducting plate 18 through the camera heat-conducting plate 19, and then transferred to the second outer transaxial heat-conducting plate 422 through the optical engine heat-conducting plate 18. Finally, the heat is transferred to the second temple module 3 through the second outer transaxial heat-conducting plate 422 and dissipated outward through the second temple module 3.
