[0084] 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.

[0085] This utility model discloses a camera module, which includes a lens unit, a first translation carrier, a focusing carrier and a base.

[0086] The lens unit may have a central axis and a fixed magnet. A first translation carrier is provided for the lens unit. The first translation carrier may be a single-layer carrier. This allows movement in both directions parallel and perpendicular to the central axis. A focusing carrier may be positioned along the central axis corresponding to the first translation carrier. A base may accommodate the first translation carrier and the focusing carrier.

[0087] The camera module disclosed in this utility model may further include a second translation carrier. The second translation carrier may be disposed along the central axis corresponding to the first translation carrier and the focusing carrier. The first translation carrier, the second translation carrier, and the focusing carrier may be sequentially arranged along the central axis. Alternatively, the second translation carrier may be disposed between the first translation carrier and the focusing carrier. The second translation carrier may be housed in a base. The arrangement of the second translation carrier improves the driving stability during shake correction. Furthermore, with the assistance of the second translation carrier, the first translation carrier can indirectly achieve movement in both directions parallel to and perpendicular to the central axis.

[0088] The camera module disclosed in this utility model may further include a translation drive module and a focus drive module.

[0089] The translation drive module can be used as a shake correction drive module. Specifically, the translation drive module includes a first translation drive unit and a second translation drive unit. The first translation drive unit and the second translation drive unit are respectively disposed in different corners of the camera module. The second translation drive unit may be disposed at least on the first translation carrier or at least on the second translation carrier, but this utility model is not limited thereto.

[0090] The first translation drive unit can move the first translation carrier along one of the axes, while the second translation drive unit can move at least one of the first and second translation carriers toward the other axis. Alternatively, the first translation drive unit can be used to move the first translation carrier relative to the second translation carrier or base along a first direction perpendicular to the central axis, while the second translation drive unit can be used to move at least one of the second and first translation carriers relative to the focusing carrier or base along a second direction perpendicular to the central axis and the first direction. However, this invention is not limited to these limitations.

[0091] The first translation drive unit includes a first translation magnet and a first translation coil. This allows relative displacement to be generated through electromagnetic force. The first translation magnet is disposed on a first translation carrier. The first translation coil is disposed relative to the first translation magnet. This improves the driving efficiency of the first translation drive unit.

[0092] The second translation drive unit includes a second translation magnet and a second translation coil. Relative displacement can be generated by electromagnetic force. The second translation magnet is disposed on either the first or second translation carrier. The second translation coil is positioned relative to the second translation magnet. Please refer to [reference needed]. Figure 6 This illustration shows a second translation magnet 152a disposed on a first translation carrier 12a according to the first embodiment of this utility model. Please refer to... Figure 8 The diagram illustrates a second translation magnet 252a disposed on a second translation carrier 22b according to a second embodiment of the present invention. When the second translation magnet is disposed on the first translation carrier, it can be used to drive the first translation carrier and simultaneously move the second translation carrier. This provides a margin in the placement design of the second translation drive unit while satisfying drive stability.

[0093] The focus drive module is positioned on the opposite side of the camera module, relative to the translational drive module. This reduces magnetic interference between the drive modules. The focus drive module can function as an autofocus drive module, enabling the focus carrier to move along a central axis. Specifically, the focus drive module includes a first focus drive unit. The first focus drive unit is positioned on one side of the camera module.

[0094] The first focusing drive unit can be used to move at least one of the focusing carrier, the second translation carrier and the first translation carrier relative to the base in a direction parallel to the central axis.

[0095] The first focusing drive unit includes a pair of focusing magnets and a pair of focusing coils. This allows relative displacement to be generated via electromagnetic force. The focusing magnets are positioned on the focusing carrier. The focusing coils are positioned relative to the focusing magnets. This improves the driving efficiency of the first focusing drive unit.

[0096] According to the camera module disclosed in this utility model, the focusing drive module may further include a second focusing drive unit. The second focusing drive unit and the first focusing drive unit are respectively disposed on different sides of the camera module. This allows for the fulfillment of higher driving force requirements. Please refer to...

Viewed along a direction parallel to the central axis, the aperture drive module is located between the focus drive module and the translation drive module. The aperture drive module includes at least one aperture drive unit. This at least one aperture drive unit controls the size of the variable aperture. The number of these at least one aperture drive units can be at least two. These at least two aperture drive units are respectively located on two other sides of the camera module, different from the first focus drive unit. Alternatively, the at least two aperture drive units can be respectively located on two other sides of the camera module where the first focus drive unit is not located.

[0100] The at least one aperture driving unit comprises an aperture magnet. A shortest distance from the aperture magnet to a central axis is D1, a shortest distance from a first translation magnet and a second translation magnet to the central axis is D2, and a shortest distance from a focusing magnet to the central axis is D3, which can satisfy the following condition: D1<D2<D3. Thereby, energy consumption requirements can be reduced. The following condition can also be satisfied: 0.33<D1 / D2<0.93. The following condition can also be satisfied: 0.48<D1 / D2<0.73. The following condition can also be satisfied: 0.27<D1 / D3<0.9. The following condition can also be satisfied: 0.45<D1 / D3<0.7. When viewed along a direction parallel to the central axis, D1, D2 and D3 are not parallel to each other. Thereby, the design margin of each driving module can be provided while reducing magnetic circuit interference. Please refer to Figure 16 , which illustrates the shortest distances D1, D2 and D3 in the fifth embodiment of the present utility model.

[0101] The camera module disclosed according to the present utility model may further comprise a flexible circuit board. The flexible circuit board is arranged around the base. The flexible circuit board can be simultaneously connected to the first translation driving unit, the second translation driving unit and the first focusing driving unit at an outer side of the base. Thereby, circuit arrangement can be simplified. The flexible circuit board has a movable part, and the movable part is electrically connected to the aperture driving module. The movable part of the flexible circuit board can have a reed function, and the movable part can elastically support the first translation carrier. Thereby, it can have both the elastic support capability while satisfying the conductive function.

[0102] The camera module disclosed according to the present utility model may further comprise a first rolling unit. The first rolling unit is arranged between the first translation carrier and the second translation carrier, and the first rolling unit guides the movement of the first translation carrier along a first direction by rolling. The first rolling unit can be at least one sphere or at least one cylinder, but the present utility model is not limited thereto. Thereby, driving friction can be reduced.

[0103] The camera module disclosed according to the present utility model may further comprise a second rolling unit. The second rolling unit is arranged between the second translation carrier and the focusing carrier, and the second rolling unit guides the movement of the second translation carrier along a second direction by rolling. The second rolling unit can be at least one sphere or at least one cylinder, but the present utility model is not limited thereto. Thereby, driving friction can be reduced.

[0104] The camera module disclosed according to the present utility model may further comprise a third rolling unit. The third rolling unit is arranged between the focusing carrier and the base, and the third rolling unit guides the movement of the focusing carrier along a direction parallel to the central axis by rolling. The third rolling unit can be at least one sphere or at least one cylinder, but the present utility model is not limited thereto. Thereby, driving friction can be reduced.

[0105] The camera module disclosed in this utility model may further include a ferromagnetic element. The ferromagnetic element is embedded in the focusing carrier. The ferromagnetic element is disposed corresponding to at least one of the first translational magnet and the second translational magnet. This provides a preload force during actuation, thereby improving actuation stability. The camera module may also include at least two ferromagnetic elements. The at least two ferromagnetic elements are respectively embedded in the first translational carrier and the focusing carrier. Both at least two ferromagnetic elements are disposed corresponding to the second translational magnet. Please refer to... Figure 8 This illustration depicts two ferromagnetic elements 294a and 294b, respectively embedded in the first translation carrier 22a and the focusing carrier 23, and each corresponding to the second translation magnet 252a, according to the second embodiment of this utility model. The ferromagnetic elements can be correspondingly arranged with the fixed magnet. Please refer to... Figure 11 The diagram illustrates a ferromagnetic element 394 arranged in accordance with the third embodiment of the present invention, corresponding to the fixed magnet 312.

[0106] According to the above configuration, the camera module disclosed in this utility model can reduce magnetic circuit interference while meeting the requirements of miniaturization design and have good driving stability by using a shake correction drive module set in the corner and at least one layer of shake correction carrier, combined with an autofocus drive module set on the side.
