[0029] As Figure 1 and Figure 2As shown, the embodiment of the present application provides an AR glasses 100, which comprises a frame 10, a first leg 20, a second leg 30 and a stack structure 40. The frame 10 comprises a front shell 11 and a rear shell 12, which are assembled to form a first accommodating space 13. The first leg 20 comprises a first shell 21 and a second shell 22, which are assembled to form a second accommodating space 23.

The third flexible circuit board 43 and the first adapter board 45 are arranged in the second accommodating space 23 of the first leg 20. The fourth flexible circuit board 44 and the second adapter board 46 are arranged in the third accommodating space 33 of the second leg 30. The first flexible circuit board 41 is electrically connected with the second flexible circuit board 42. The first flexible circuit board 41 is electrically connected with the third flexible circuit board 43 through the first adapter board 45. The first flexible circuit board 41 is electrically connected with the fourth flexible circuit board 44 through the second adapter board 46.
[0031] In the embodiment, the flexible circuit boards (the first flexible circuit board 41, the second flexible circuit board 42, the third flexible circuit board 43 and the fourth flexible circuit board 44) arranged in the AR glasses 100 are bendable and have strong adaptability, and can be freely bent, wound and folded. Therefore, the flexible circuit boards can be arranged arbitrarily according to the space layout requirements inside the legs (the first leg 20 and the second leg 30), and can be moved and stretched arbitrarily in three-dimensional space. Thus, the flexible circuit boards can better adapt to the shape and limited space of the legs, which helps to realize the miniaturization and lightweight design of the AR glasses 100.
[0032] Moreover, compared with the hard circuit board, the flexible circuit board is thin and light in itself, which can save space and weight, greatly reduce the volume and weight of the legs, and thus greatly reduce the volume and weight of the electronic product, which helps to realize the miniaturization and lightweight design of the AR glasses 100, and also meets the requirements of portability and wearing comfort of the AR glasses 100.
[0033] For example, Figure 1 And Figure 2In a specific embodiment, one end of the first flexible circuit board 41 extends from the first accommodating space 13 to the second accommodating space 23 along the length direction of the frame 10 to extend into the second accommodating space 23, so as to be electrically connected with the third flexible circuit board 43 through the first adapter board 45 arranged in the second accommodating space 23; the other end of the first flexible circuit board 41 extends from the first accommodating space 13 to the second accommodating space 23 along the length direction of the frame 10 to extend into the second accommodating space 23, so as to be electrically connected with the fourth flexible circuit board 44 through the second adapter board 46 arranged in the third accommodating space 33.

At the same time, the flexible FPC board has high integration, can realize multi-layer wiring and high-density integration, so as to integrate more electronic elements and lines in the limited temple space, such as integrated camera 14, sensor, LED lamp, chip, etc., to meet the complex functional requirements of the AR glasses.
[0036] Further, the first adapter board 45, the second adapter board 46 and the main control board 24 can all be hard circuit boards. Firstly, the hard circuit boards have high mechanical strength, specifically, the hard circuit boards have good rigidity and mechanical strength, and can provide stable support for components, for example, when the AR glasses 100 are subjected to external forces such as impact and extrusion, the components can be better protected from damage, and the reliability and stability of the AR glasses 100 can be improved. Secondly, the hard circuit boards are easy to repair and replace, specifically, when the components on the first adapter board 45, the second adapter board 46 and the main control board 24 fail, it is easier to detect, repair and replace them, for example, maintenance personnel can quickly locate and handle the problem through conventional tools and methods, reducing equipment maintenance time and cost. Thirdly, the electrical performance of the hard circuit boards is stable, especially in high-frequency and high-speed signal transmission, the performance of the hard circuit boards is relatively stable, which can better ensure the integrity and accuracy of the signals, reduce signal distortion and interference, and is suitable for AR glasses 100 with high signal quality requirements.
[0037] As shown in Figure 1 Overall, the stack structure 40 of the AR glasses 100 of the present embodiment combines the use of flexible FPC boards and PCB boards, which can reduce the volume and weight of the AR glasses 100 while ensuring the performance of the AR glasses 100, and is conducive to the miniaturization and lightweight design of the AR glasses 100.

Further, in one embodiment of the present application, the second adapter plate 46 is accommodated in the third flat portion 331, and the battery 34 is accommodated in the fourth flat portion 333, and in another embodiment of the present application, the second adapter plate 46 is accommodated in the fourth flat portion 333, and the battery 34 is accommodated in the third flat portion 331.

The third flexible circuit board 43 separates the first adapter board 45 and the main control board 24, so that the strong electromagnetic interference source (such as high-frequency radio frequency circuit or high-power power conversion circuit) existing on the main control board 24 does not affect the performance of the microphone chip arranged on the first adapter board 45. Moreover, when the wearer communicates with others by voice, such as emitting sound and receiving the sound of others, the sound comes from the front of the wearer, so the microphone chip is placed in the front of the wearer, rather than close to the ear, i.e. close to the audio input source, rather than directly on the main control board 24, which is beneficial to better capture the sound signal.

[0048] In this embodiment, the wearing detection assembly 90 is used to detect whether the AR glasses 100 are in a wearing state, specifically, the FPC circuit board on the inner side of the fourth flexible circuit board 44 detects whether the AR glasses 100 are in a wearing state or an unwearing state by detecting the change of capacitance.
[0049] More specifically, when the AR glasses 100 are worn on the face of the wearer, the FPC circuit board on the inner side of the fourth flexible circuit board 44 detects that the unwearing state changes to the wearing state, so that the AR glasses 100 in the wearing state can realize the functions of automatic starting, waking up or starting the electrical element; when the wearer takes off the AR glasses 100, the FPC circuit board on the inner side of the fourth flexible circuit board 44 detects that the wearing state changes to the unwearing state, so that the AR glasses 100 in the unwearing state can realize the functions of automatic shutdown, hibernation or closing the electrical element.
