IMAGING LENS DRIVING MODULE, CAMERA MODULE AND ELECTRONIC DEVICE

BACKGROUND
Technical Field

The present disclosure relates to an imaging lens driving module, a camera module and an electronic device, more particularly to an imaging lens driving module and a camera module applicable to an electronic device.

Description of Related Art

With the development of semiconductor manufacturing technology, the performance of image sensors has been improved, and the pixel size thereof has been scaled down. Therefore, featuring high image quality becomes one of the indispensable features of an optical system nowadays. Furthermore, due to the rapid changes in technology, electronic devices equipped with optical systems are trending towards multi-functionality for various applications, and therefore the functionality requirements for the optical systems have been increasing.

In recent years, there is an increasing demand for electronic devices featuring compact size, but conventional optical systems are difficult to meet both the requirements of high image quality and compactness. Conventional camera modules usually have functionalities such as auto focus, optical image stabilization and optical zoom. However, in order to achieve the above functionalities, the structure of the camera modules becomes more complex and the size thereof also increases, and thus, the size of electronic devices equipped with the camera modules also increases. In addition, in order to achieve auto focus and optical zoom functionalities, the camera modules are usually provided with lens driving units so as to drive the lens system to move along the optical axis. However, in conventional lens driving units, there are usually larger assembly errors between elastic elements and movable lens carriers, and there is usually a problem of assembly warpage so that the elastic elements may be installed unevenly and thus tilts, thereby increasing defective rate of the lens driving units.

DETAILED DESCRIPTION

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.

The present disclosure provides an imaging lens driving module. The imaging lens driving module includes a lens carrier, a frame element, a driving mechanism and a metal conductive element. The lens carrier is configured for holding an imaging lens system. The frame element forms an interior space for the lens carrier to be disposed therein. The driving mechanism is configured for driving the lens carrier to move in a direction parallel to an optical axis of the imaging lens system. The metal conductive element is coupled to the lens carrier.

The driving mechanism includes a metal elastic element, a coil and a magnet assembly. The metal elastic element includes an outer fixing part, an inner fixing part and an elastic part. The outer fixing part is coupled to the frame element. The inner fixing part is located closer to the lens carrier than the outer fixing part to the lens carrier, and the inner fixing part is coupled to the lens carrier. The elastic part is connected to the outer fixing part and inner fixing part. The coil is fixed to the lens carrier, and the magnet assembly is disposed corresponding to the coil.

The metal elastic element further includes an electrically connecting part and a compensating elastic part. The metal conductive element has a corresponsive surface disposed corresponding to and electrically connected to the electrically connecting part. The compensating elastic part is connected to the electrically connecting part and the inner fixing part. Therefore, the flatness of the metal elastic element can be compensated so as to prevent the metal elastic element from tilting, thereby increasing manufacturing yield rate of the imaging lens driving module. Said electrical connection can be achieved by a welding process or dispensing process, and the present disclosure is not limited thereto. Moreover, the compensating elastic part of the metal elastic element can correct extra assembly errors and reduce the possibility of assembly warpage of the metal elastic element. Furthermore, the compensating elastic part of the metal elastic element can at least ensure that the electrically connecting part and the corresponsive surface of the metal conductive element are at least partially in physical contact with each other. Please refer to FIG. 15, which is an enlarged schematic view of the electrically connecting part 1515 of the metal elastic element 151 and the corresponsive surface 161 of the metal conductive element 16 during an assembly process according to the 1st embodiment of the present disclosure. As seen, the electrically connecting part 1515 and the corresponsive surface 161 are at least partially in physical contact with each other. Moreover, the compensating elastic part is a relatively weak part in structural strength of the metal elastic element.

The electrically connecting part of the metal elastic element can overlap the corresponsive surface of the metal conductive element in the direction parallel to the optical axis. Therefore, the electrically connection position between the metal elastic element and the metal conductive element can be more easily positioned during an automated manufacturing process, thereby improving manufacturing efficiency.

When a sectional area of the elastic part of the metal elastic element is A0, and a minimum sectional area of the compensating elastic part of the metal elastic element is A1, the following condition can be satisfied: 0.05<A1/A0<2.0. Therefore, it can be ensured that the warpage of the metal elastic element occurs at the compensating elastic part thereof during the assembly process, thereby reducing assembly errors. Moreover, the following condition can also be satisfied: 0.1<A1/A0<1.3, which corresponds to different structural design of the compensating elastic part, and the condition defines a range for better reducing assembly warpage. Please refer to FIG. 20, FIG. 22, FIG. 24 and FIG. 26, which show schematic views of A0 and A1 according to the 1st embodiment of the present disclosure.

The metal conductive element can be disposed between the lens carrier and the electrically connecting part of the metal elastic element. Therefore, the metal conductive element can absorb collision forces during the assembly process so as to ensure good resolution quality of the imaging lens system. In one configuration, each metal conductive element can have at least two fastening holes, such that the metal conductive element is unable to rotate, thereby improving assembly efficiency.

The electrically connecting part of the metal elastic element can be in physical contact with the corresponsive surface of the metal conductive element. Therefore, if the metal elastic element warps, it is ensured that the electrically connecting part and the corresponsive surface are still at least partially in physical contact with each other, and optionally, an electrical conductive material can be filled in an air gap between the electrically connecting part and the corresponsive surface so as to ensure that the stability of electrical connection therebetween is not compromised by the assembly warpage.

There can be a tapered air gap between the electrically connecting part of the metal elastic element and the corresponsive surface of the metal conductive element. Therefore, the air gap being tapered towards the contact point of the electrically connecting part and the corresponsive surface ensures that the electrically connecting part and the corresponsive surface are at least partially in physical contact with each other, thereby ensuring the electrical connection therebetween.

The present disclosure provides another imaging lens driving module. The imaging lens driving module includes a lens carrier, a frame element, a driving mechanism and a metal conductive element. The lens carrier is configured for holding an imaging lens system. The frame element forms an interior space for the lens carrier to be disposed therein. The driving mechanism is configured for driving the lens carrier to move in a direction parallel to an optical axis of the imaging lens system. The metal conductive element is coupled to the lens carrier.

The metal conductive element includes an electrically connecting part and a compensating elastic part. The metal elastic element has a corresponsive surface disposed corresponding to and electrically connected to the electrically connecting part. The compensating elastic part is connected to the electrically connecting part. Therefore, the flatness of the metal conductive element can be compensated so as to prevent the metal conductive element from tilting, thereby reducing manufacturing cost. Said electrical connection can be achieved by a welding process or dispensing process, and the present disclosure is not limited thereto. Moreover, the metal conductive element can be a wire electrically connected to the coil and the metal elastic element. Furthermore, the corresponsive surface of the metal elastic element can be a compatible step surface having a structure of a recessed surface area. Please refer to FIG. 84 and FIG. 87, which show schematic views of the corresponsive surface 1516f of the metal elastic element 151f according to the 6th embodiment of the present disclosure.

The electrically connecting part of the metal conductive element can overlap the corresponsive surface of the metal elastic element in the direction parallel to the optical axis. Therefore, the electrically connection position between the metal conductive element and the metal elastic element can be more easily positioned during an automated manufacturing process, thereby improving manufacturing efficiency.

When a sectional area of the elastic part of the metal elastic element is A0, and a minimum sectional area of the compensating elastic part of the metal conductive element is A1, the following condition can be satisfied: 0.1<A1/A0<1.3. Therefore, it can be ensured that the warpage of the metal conductive element occurs at the compensating elastic part thereof during the assembly process, thereby reducing assembly errors. Please refer to FIG. 86, FIG. 88, FIG. 92 and FIG. 94, which show schematic views of A0 and A1 according to the 6th embodiment of the present disclosure.

The metal elastic element can be disposed between the lens carrier and the electrically connecting part of the metal conductive element. Therefore, the metal conductive element can absorb collision forces during the assembly process so as to ensure good resolution quality of the imaging lens system.

According to the present disclosure, the aforementioned features and conditions can be utilized in numerous combinations so as to achieve corresponding effects.
