[0072] Through the corresponding connection between the first connection post 4114 and the first connection hole 4121, the corresponding connection between the second connection post 4115 and the second connection hole 4122, the corresponding connection between the connection bent plate 4117 and the bent plate connection hole 4124, and the corresponding cooperation of the guide post 4116 being movably inserted into the guide hole 4123, firm fixation between the first main circuit board 412 and the first main board bracket 411, and between the second main circuit board 422 and the second main board bracket 421 is achieved, while providing accurate positioning and guidance; the design of the connection bent plate 4117 increases the stability of the connection and provides additional structural support to protect the circuit board assembly 4 from external impacts or stresses; the design of this multi-connection point and support structure can improve the overall reliability and durability of the AR glasses;

[0073] The design of the insertion slot 4212 formed by enclosing the connection bent plate 4117 and the bracket body 4111 can achieve the positioning and fixation of the side edge of the circuit board body 4131; by inserting the circuit board body 4131 into the insertion slot 4212 and making the side edge of the circuit board body 4131 press-fit with the inner side wall of the insertion slot 4212, the limiting and supporting of the first camera driving circuit board 413 and the second camera driving circuit board 423 can be realized, improving the stability and seismic resistance during the working process; the design of this insertion slot 4212 reduces the risk of damage to the first camera driving circuit board 413 and the second camera driving circuit board 423 during the insertion and removal processes, and at the same time ensures the compact layout of the internal components of the AR glasses, which is beneficial to reducing the volume of the device, improving the comfort and aesthetics of the user's wearing.

[0074] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
