Patent Application
20210055499
The subject matter of the application generally relates to a lens module.
Electronic devices, such as mobile phones, tablet computers or cameras, may have lens modules. Since magnetic interference will affect image quality of the lens module, a strong electromagnetic shielding capability is needed.

The electrical connection portion 116 is used to implement signal transmission between the lens module 100 and the electronic device 200. A reinforcing plate 118 is mounted on the second surface 114. The reinforcing plate 118 is for reinforcing the hardness of the first rigid portion 11. In at least one embodiment, the electrical connection portion 116 can be mounted on the second surface 114 and the electrical connection portion 116 can be mounted on the first surface 112.
The second rigid portion 12 includes a third surface 122 and a fourth surface 124 opposite to the third surface 122. The third surface 122 and the first surface 112 are on a same side of the printed circuit board 10. The fourth surface 124 and the second surface 114 are on a same side of the printed circuit board 10. A sensor (not shown) and a plurality of electronic components 128 are mounted on the fourth surface 124. The electronic components 128 can be components such as a resistor, a capacitor, a diode, a transistor, a relay, or an electrically erasable programmable read only memory (EEPROM).
In at least one embodiment, the bearing seat 20 is mounted on the fourth surface 124. In other embodiment, the bearing seat 20 can be mounted on the third surface 122.
The microscope base 30 is mounted on the bearing seat 20 and opposite to the printed circuit board 10. The microscope base 30 is roughly a rectangular structure.
In at least one embodiment, the microscope base 30 and the lens 40 are an integral structure. The lens 40 includes a first lens portion 42, a second lens portion 44, and a third lens portion 46. The second lens portion 42 connects to the first lens portion 41 and the third lens portion 43. Diameters of the first lens portion 41, the second lens portion 42, and the third lens portion 43 sequentially decrease. The first lens portion 41, the second lens portion 42, and the third lens portion 43 are assembled or integrally formed. In the embodiment, the first lens portion 41, the second lens portion 42, and the third lens portion 43 are integrally formed.
In
In at least one embodiment, the first steel sheet 54 includes a bottom plate 542, a first baffle portion 544, and a second baffle portion 546. The bottom plate 542 is substantially rectangular. The bottom plate 542 is slightly larger in size than the second rigid portion 12. The first baffle portion 544 and the second baffle portion 546 are vertically formed on the bottom plate 542. The first baffle portion 544 and the second baffle portion 546 are formed on two sides of the bottom plate 542. The first baffle portion 544 is connected to the second baffle portion 546.
The second steel sheet 56 includes a third baffle portion 561, a fourth baffle portion 562, a fifth baffle portion 563, a sixth baffle portion 564, a top plate 565, a first side wall 566, and a second side wall 567. The first opening 52 is defined in the fifth baffle portion 563. The top plate 565 is hollow and is rectangular. A through hole 5651 is defined in the top plate 565. The third baffle portion 561, the fourth baffle portion 562, the fifth baffle portion 563, and the sixth baffle portion 564 are sequentially connected to each other end to end and vertically formed on the same side of the top plate 565. In at least one embodiment, the third baffle portion 561, the fourth baffle portion 562, the fifth baffle portion 563, and the sixth baffle portion 564 are perpendicular to the top plate 565 and formed around the top plate 565. The third baffle portion 561, the fourth baffle portion 562, the fifth baffle portion 563, and the sixth baffle portion 564 extend outside from the top plate 565. The first side wall 566 is formed on the top plate 565 around the through hole 5651. The second side wall 567 is formed on the first side wall 566. The first side wall 566 and the third baffle portion 561 are on two opposite surfaces of the top plate 565. The first side wall 566 encloses a cylinder. The second side wall 567 encloses a cylinder and forms the second opening 53. The cylinder enclosed by the second side surface 567 has a diameter smaller than a diameter of the cylinder enclosed by the first side wall 566.

The first steel sheet 54 is electrically connected to the printed circuit board 10. In at least one embodiment, the first steel sheet 54 is electrically connected to the printed circuit board 10 by a conductive adhesive 60 formed on the bottom plate 542 in
Further, at least one adhesive 62 is formed between the first steel sheet 54 and the second rigid portion 12 to fix the first steel sheet 54 and the second rigid portion 12.
In other embodiments, the shield 50 includes a first steel sheet 54 and a second steel sheet 56. The first steel sheet 54 and the second steel sheet 56 are mutually symmetrical structures. The first steel sheet 54 and the second steel sheet 56 are combined with each other to form a shielding cover 50 including the first opening 52 and the second opening 53.
It can be understood that a shape and a size of the shielding cover 50 vary with an overall shape and a size of the printed circuit board 10, the bearing seat 20, the microscope base 30, and the lens 40 after assembly, and are not limited to the shape and size as described above.
With the embodiments described above, the shielding cover 50 can filter the magnetic interference of the external signal, facilitate heat generated by the lens module 100 dissipate outside, and support the lens module 100.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a lens module and an electronic device using the lens module. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present disclosure have been positioned forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes can be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above can be modified within the scope of the claims.
