[0086] The detailed features and advantages of this utility model are described below in the embodiments. The content is sufficient for any person skilled in the art to understand the technical content of this utility model and to implement it accordingly. Furthermore, based on the disclosure, claims, and drawings in this specification, any person skilled in the art can easily understand the related objectives and advantages of this utility model. The following embodiments further illustrate the viewpoints of this utility model in detail, but are not intended to limit the scope of this utility model in any way.

[0087] This utility model provides a camera module, which includes at least one lens unit, one top cover, one fixed part, one movable part, one drive module, and one ferromagnetic element group.

[0088] The at least one lens unit has a central axis. The top cover has at least one light-transmitting hole. The at least one light-transmitting hole corresponds to the at least one lens unit in the direction of the central axis. The number of the at least one lens unit can be at least two, and the number of the at least one light-transmitting hole can be at least two, with the at least two lens units and the at least two light-transmitting holes respectively correspondingly arranged. This allows the camera module to become a dual-lens module and provides design margin in terms of the number of lens units. For example, one lens unit can be designed as an infrared lens (IRlens), while the other lens unit can be designed as a visible light lens. However, this invention is not limited to this. In some embodiments, the number of both the at least one lens unit and the at least one light-transmitting hole can be one, making the camera module a single-lens module.

[0089] A fixed part is provided corresponding to the top cover. A movable part is movable relative to the fixed part. The movable part may have a main body and at least one light-shielding plate. The at least one light-shielding plate may be provided on the main body. The at least one light-shielding plate and the main body may be multi-piece components that can be assembled and disassembled, thereby reducing the difficulty of driving. However, this utility model is not limited thereto. The at least one light-shielding plate may also be integrally formed on the main body. This reduces assembly steps.

[0090] The at least one light-shielding plate may have a shading area and a light-transmitting area. The number of light-transmitting areas may be multiple, and the at least one light-shielding plate has these light-transmitting areas. This allows for a design margin in the number and size of the light-transmitting areas while meeting light-shielding requirements; furthermore, it can provide a function similar to a variable aperture. Please refer to... Figure 24 This is a schematic diagram illustrating a plurality of light-transmitting areas 6422 in the sixth embodiment of the present invention.

[0091] The driving module includes at least one magnet and at least one coil. The at least one magnet is disposed on a movable part. The at least one coil is disposed corresponding to the at least one magnet. When the driving module drives the movable part to an open end, the light-transmitting area corresponds to the at least one light-transmitting hole. This exposes the at least one lens unit. When the driving module drives the movable part to a closed end, the shielding area corresponds to the at least one light-transmitting hole. This shields the at least one lens unit.

[0092] The ferromagnetic element assembly is at least partially embedded in the fixing part. In some cases, it can also be interpreted as the ferromagnetic element assembly being at least partially inserted into or embedded in the fixing part, and this invention is not limited thereto. The ferromagnetic element assembly can be embedded in the fixing part through injection molding. This simplifies the product assembly process.

[0093] A ferromagnetic element assembly provides a first magnetic force to the at least one magnet along a first direction, fixing the movable part to the open or closed end. Furthermore, the ferromagnetic element assembly provides a second magnetic force to the at least one magnet along a second direction different from the first direction, causing the movable part and the fixed part to be attracted by a positive attractive force. This reduces energy consumption during operation. When the at least one magnet is located at the open or closed end, it can be attracted by both the first and second magnetic forces simultaneously. This reduces manufacturing costs. The first direction can be perpendicular to the central axis of the at least one lens unit. This provides a preferred direction of the first magnetic force. The second direction can be parallel to the central axis of the at least one lens unit. This provides a preferred direction of the second magnetic force. The ferromagnetic element assembly can partially overlap the at least one magnet in the first and second directions. This increases the strength of the magnetic attraction.

[0094] With the above configuration, the camera module can drive the movable part through the at least one magnet and the at least one coil. Combined with the ferromagnetic element group embedded in the fixed part, it provides a first magnetic force while providing a second magnetic force, thereby satisfying the driving stability and user privacy and security.

[0095] The ferromagnetic element assembly includes at least one ferromagnetic element. The number of said at least one ferromagnetic element may be one. This reduces process steps and manufacturing time. Please refer to... Figure 22This is a schematic diagram illustrating a single ferromagnetic element 561 according to the fifth embodiment of the present invention. The number of the at least one ferromagnetic element can be at least two, and the at least two ferromagnetic elements are arranged separately from each other. This ensures the functionality of the ferromagnetic element while providing design margin in terms of the number of ferromagnetic elements. One of the at least two ferromagnetic elements provides a first magnetic force to the at least one magnet, and the other of the at least two ferromagnetic elements provides a second magnetic force to the at least one magnet. This improves the design flexibility of the ferromagnetic element. The number of the at least one ferromagnetic element can be six. Please refer to... Figure 4 This is a schematic diagram illustrating six ferromagnetic elements 161 in the first embodiment of the present invention.

[0096] The camera module disclosed in this utility model may further include a flexible circuit board. When the number of the at least one ferromagnetic element is at least two, the flexible circuit board is electrically connected to the at least two ferromagnetic elements, and each of the at least two ferromagnetic elements has a terminal on the side away from the fixing part. This allows the motherboard of the electronic device to be connected via the terminal, and the flexible circuit board and coil to be powered via the ferromagnetic elements, enabling the ferromagnetic elements to be multifunctional. Please refer to... Figure 2 , Figure 4 and Figure 5 This is a schematic diagram illustrating the flexible circuit board 17, the terminals 1611 of the ferromagnetic element 161, and the energized portion EP of the ferromagnetic element 161 in the first embodiment of this utility model. However, this utility model is not limited thereto. In some embodiments, the flexible circuit board may also connect to the motherboard of the electronic device. Please refer to... Figure 20 This is a schematic diagram illustrating the flexible circuit board 57 in the fifth embodiment of the present invention.

[0097] According to the camera module disclosed in this utility model, the movable part may also have an elastic element to act as a buffer between the movable part and the fixed part. This reduces the impact force and noise between the movable part and the fixed part.

[0098] The camera module disclosed in this utility model may further include a guide portion. The guide portion is disposed between the movable portion and the fixed portion, and guides the movable portion to move relative to the fixed portion along a first direction. This reduces the power requirements of the camera module. The guide portion may be spherical and is rollably disposed between the movable portion and the fixed portion. The guide portion can guide the movable portion to move relative to the fixed portion along the first direction by rolling. This reduces friction during operation. Please refer to... Figures 2 to 3 This illustration shows a plurality of guide portions 18 that are rotatably disposed between the movable portion 14 and the fixed portion 13 in the first embodiment of this utility model. The guide portions may also be integrally formed within the movable portion. Please refer to... Figures 16 to 17The illustration shows a plurality of guide portions 38 integrally formed on the movable portion 34 in the third embodiment of the present invention. Please note that the shape of the guide portions is not limited to this invention. In some embodiments, the guide portions may also be cylindrical.
