[0014] In one embodiment, the flexible circuit board has a first side and a second side disposed opposite to each other;

[0015] The first mounting position is arranged on a first side of the flexible circuit board, and a reinforcing piece is arranged on a second side of the flexible circuit board at a position corresponding to the first mounting position.

[0016] In one embodiment, a first welding area is provided on the lighting module, and the second connecting member is a flexible circuit board; the first end of the second connecting member is connected to the optical engine driving board, and the second end of the second connecting member is welded to the first welding area, and the lighting module establishes an electrical connection path with the optical engine driving board via the flexible circuit board.

At the same time, it should be understood that the imaging module, the optical-mechanical driving board and the illumination module of the existing optical-mechanical assembly are connected by snapping, and the snapping connection often relies on the close fit between the mechanical parts to maintain the stability of the connection. However, since the mechanical parts may be affected by external factors such as vibration and impact during use, the snapping parts are prone to loosening or deformation, resulting in an unreliable connection. Since the flexible circuit board is connected to the optical-mechanical driving board by a combination of soft and hard, its connection strength is much higher than the snapping connection. Therefore, replacing the connector with a flexible circuit board can greatly reduce the risk of an unreliable connection and improve the overall stability and reliability of the optomechanical assembly.

[0025] In addition, since the imaging module, the optical drive board and the lighting module of the existing optical-mechanical assembly are connected by a connector, they cannot be patched together when connected by a connector, so that the imaging module, the optical drive board and the lighting module need to be patched separately, resulting in a large number of patching times for the optical-mechanical assembly; and when testing, it is also necessary to develop corresponding test machines for the imaging module, the optical drive board and the lighting module, respectively, which requires a lot of development costs and time costs. In the present application, since the imaging module, the optical drive board and the lighting module are interconnected by a flexible circuit board, the imaging module, the optical drive board and the lighting module can be patched as a PCB board, and there is no need to patch the imaging module, the optical drive board and the lighting module separately, thereby reducing the number of patching times of the optical-mechanical assembly and saving patching costs. And for R&D personnel, it is only necessary to design a test machine for the PCB board formed by connecting the imaging module, the optical drive board and the lighting module through a flexible circuit board, without the need to develop multiple test machines, thereby saving the cost of developing the test machine and reducing the time required for testing the optical-mechanical assembly. Moreover, the PCB board formed by connecting the imaging module, optomechanical driver board and lighting module through a flexible circuit board can be used as a separate material. Compared with the existing optomechanical components, the imaging module, optomechanical driver board and lighting module are three separate materials, which reduces the types and quantities in the bill of materials, thereby simplifying the complexity of material management and making material management more convenient.

[0040] The optical machine of AR glasses is an important component of AR glasses and is the component that generates images. However, the electrical connection between multiple modules in the existing optical machine is realized through connectors, and the interconnected modules need to be connected through two male and female connectors. In this way, the existing optical machine is equipped with multiple connectors, but multiple connectors will take up more space, which is not conducive to the lightweight and miniaturized design of AR glasses.

[0041] To this end, in one embodiment of the present application, refer to Figure 1 , the optical-mechanical assembly includes an imaging module 10, an optical-mechanical driving board 20 and an illumination module 30 which are electrically connected in sequence;

[0042] The optical-mechanical driving board 20 is electrically connected to the imaging module 10 via a first connecting member 40 , and the optical-mechanical driving board 20 is electrically connected to the lighting module 30 via a second connecting member 50 ;

[0043] Wherein, at least one of the first connecting member 40 and the second connecting member 50 is a flexible circuit board, and the flexible circuit board is connected to the optical engine driving board 20 .

[0044] In this embodiment, the imaging module 10 includes a display component and a plurality of optical devices for displaying images. Among them, the display component can be implemented by a silicon-based liquid crystal display module (Liquid Crystal on Silicon, LCOS). The LCOS panel belongs to a new type of reflective micro-LCD projection technology. It uses a CMOS integrated circuit chip coated with liquid crystal silicon as a substrate of a reflective LCD. After being polished, it is plated with aluminum as a reflector to form a CMOS substrate. The CMOS substrate is then bonded to a glass substrate containing a transparent electrode and liquid crystal is injected into the package. After receiving the light emitted by the lighting module 30, the reflection state of each pixel of the silicon-based display panel can be controlled, thereby realizing the reflection of light at different positions, and then forming the image to be presented. The lighting module 30 is implemented by an LED component to provide a backlight source for the imaging module 10. The optical drive board 20 is used to receive data (such as a video stream or a picture, etc.) from an external terminal (such as a smart phone, a computer or other device), and processes the received data through a built-in processor to adjust the direction, intensity and color of the light emitted by the lighting module 30 according to the received data to adjust the image displayed by the imaging module 10. The optical engine driving board 20 is also used to provide power to the imaging module 10 and the lighting module 30 .

[0045] Optionally, the first connector 40 and the second connector 50 can both be flexible circuit boards to save the space originally occupied by the connector to the greatest extent. Optionally, the R&D personnel can also set one of the first connector 40 and the second connector 50 as a flexible circuit board according to the needs of the structural layout in the actual device, and the other one is still implemented by a connector.

[0046] In this embodiment, the flexible circuit board can be implemented by using an FPC soft board, and the FPC soft board is connected to the optical-mechanical driving board 20 through a soft-hard combination process, that is, after the FPC soft board and the optical-mechanical driving board 20 are stacked, a pressing operation is performed by a specific pressing device under set conditions of temperature, pressure, time, etc., so that they are tightly combined into a whole. After the FPC soft board is connected to the optical-mechanical driving board 20, the FPC soft board is electrically connected to the imaging module 10 and / or the lighting module 30 by direct welding, that is, the pads, copper foil or gold-plated contacts on the FPC soft board are welded to the corresponding solder joints on the imaging module 10 and / or the lighting module 30.

[0047] In summary, the optical-mechanical assembly of the present application includes an imaging module 10, an optical-mechanical driving board 20 and an illumination module 30 which are electrically connected in sequence, the driving board is electrically connected to the imaging module 10 through a first connector 40, and the driving board is electrically connected to the illumination module 30 through a second connector 50; wherein, at least one of the first connector 40 and the second connector 50 is a flexible circuit board, and the flexible circuit board is connected to the optical-mechanical driving board 20. In this way, the present application replaces at least two connectors in the existing optical-mechanical assembly with flexible circuit boards, which saves the space occupied by the original connectors compared to the prior art, thereby reducing the space occupied by the optical-mechanical assembly of the present application in the device. At the same time, it should be understood that the imaging module, the optical-mechanical driving board and the illumination module of the existing optical-mechanical assembly are connected by snapping, and the snapping connection often relies on the close fit between the mechanical components to maintain the stability of the connection. However, since the mechanical components may be affected by external factors such as vibration and impact during use, the snapping parts are prone to loosening or deformation, resulting in an unreliable connection. Since the flexible circuit board is connected to the optical-mechanical driving board 20 by a combination of hard and soft, its connection strength is much higher than that of a snap-fit ​​connection. Therefore, replacing the connector with a flexible circuit board can greatly reduce the risk of an unreliable connection and improve the overall stability and reliability of the optical-mechanical assembly.

[0048] In addition, since the imaging module 10, the optical drive board 20 and the lighting module 30 of the existing optical-mechanical assembly are connected by a connector, they cannot be mounted together when connected by the connector, so that the imaging module 10, the optical drive board 20 and the lighting module 30 need to be mounted separately, resulting in a large number of mounting times for the optical-mechanical assembly; and when testing, it is also necessary to develop corresponding test machines for the imaging module 10, the optical drive board 20 and the lighting module 30, respectively, which requires a large amount of development cost and time cost. In the present application, since the flexible circuit board is connected to the optical drive board 20 by a combination of soft and hard, the imaging module 10, the optical drive board 20 and the lighting module 30 can be mounted as a PCB board, and there is no need to mount the imaging module 10, the optical drive board 20 and the lighting module 30 separately, thereby reducing the number of mounting times for the optical-mechanical assembly and saving mounting costs. Moreover, for the R&D personnel, they only need to design a test machine for the PCB board formed by the imaging module 10, the optical drive board 20 and the lighting module 30 connected by the flexible circuit board, without developing multiple test machines, thereby saving the cost of developing the test machine and reducing the time required for testing the optical machine components. Moreover, the PCB board formed by the imaging module 10, the optical drive board 20 and the lighting module 30 connected by the flexible circuit board can be used as a separate material, compared with the existing optical machine components where the imaging module 10, the optical drive board 20 and the lighting module 30 are three separate materials, reducing the types and quantities in the bill of materials, thereby simplifying the complexity of material management and making material management more convenient.
