no. 2 approach

[0054] see Figure 4 , the second embodiment of the present invention provides a lens module 200 . The lens module 200 is basically the same as the lens module 100 of the first embodiment, except that one end of the flexible circuit board 30a protrudes from the bottom of the lens barrel 10a, and the edge of the other end of the flexible circuit board 30a is in contact with the lens barrel. The inside of the lens barrel 10a abuts against and is accommodated in the second receiving cavity 13a, so that there is no need to open a through hole 15 on the lens barrel 10a for the flexible circuit board 30a to pass through.

no. 3 approach

[0056] see Figure 5 and Figure 6 , the third embodiment of the present invention provides a lens module 300 . The lens module 300 is basically the same as the lens module 200 of the second embodiment, except that a pivot shaft 17b and a locking hole 19b are provided at the bottom of the lens barrel 10b, and the pivot shaft 17b connects from the lens barrel 10b extends from the bottom. The electromagnetic shielding cover 50b includes a bottom portion 51b and a plurality of side portions 53b connected in succession, and the cross section of the side portion 53b along the direction of the optical axis L is trapezoidal. Two protrusions 55b are arranged on the top surface of the side part 53b, and pivot holes 550b are correspondingly opened on the two protrusions 55b. It is pivotally connected with the lens barrel 10b and can rotate relative to the lens barrel 10b. An elastic hook 19b is provided on the top surface of the side part 53b opposite to the pivot shaft 17b, and the...

Abstract

The invention relates to a lens module which comprises a lens barrel, a flexible circuit board, an image sensor and an electromagnetic shielding case, wherein the lens barrel is provided with a first accommodating cavity and a second accommodating cavity communicated with the first accommodating cavity; at least one optical lens is accommodated in the first accommodating cavity; a glass cover board is accommodated in the second accommodating cavity; the flexible circuit board is adhered to the surface of the glass cover board, which is far away from the first accommodating cavity; at least one end of the flexible circuit board extends out of the lens barrel from the inside of the lens barrel; a through opening is formed on the flexible circuit board; a plurality of bonding pads and a plurality of zero potential junctions are formed on the surface of the flexible circuit board, which is far away from the glass cover board; the image sensor comprises a photosensitive region and a signal region; the photosensitive region is over against the opening; the signal region is provided with second bonding pads corresponding to the first bonding pads; the second bonding pads are electrically connected with the first bonding pads; the electromagnetic shielding case is provided with an accommodating groove for accommodating the image sensor, is attached to the flexible circuit board and is grounded through the zero potential junctions. The invention also provides a portable electronic device using the lens module.

Description

technical field [0001] The invention relates to a lens module and a portable electronic device using the lens module. Background technique [0002] Portable electronic devices such as digital cameras, video cameras and mobile phones with cameras are more and more popular among consumers, and because the volume of the above-mentioned portable electronic devices is becoming smaller and smaller, it is necessary to continuously improve the performance of the internal camera devices. Encapsulation structure makes it smaller. [0003] Existing camera devices generally include a lens module, an image sensor, and a printed circuit board (PCB) electrically connected to the image sensor. The image sensor includes a sensor chip and a ceramic base, and the sensor chip is arranged on the ceramic base for fixing. The packaging method of the image sensor and the printed circuit board is generally as follows: the printed circuit board is arranged on the side of the ceramic substrate away ...
