Problems solved by technology

Due to the limitation of processing accuracy and material, during debugging, the torque between the lens barrel and the lens base will appear torsion jump, torque mutation and other torque unevenness
The phenomenon of uneven torque can easily lead to focus adjustment, and the inability to accurately fix the lens barrel to the optimal position of the desired image during dispensing, resulting in out-of-focus, affecting the analysis and performance of the camera module, resulting in reduced yield and increased production costs

[0057] see Figures 1 to 3 , is a camera module 100 provided by the present invention. The camera module 100 includes a circuit board 10 , an image sensor 20 electrically connected to the circuit board 10 , a lens mount 30 disposed on the circuit board 10 , and the mirror mount 30 Matching lens barrel 40. The camera module 100 can be used in vehicle cameras, security cameras and the like.

[0058] The circuit board 10 is a rigid board, a flexible board or a rigid-flex board. In this embodiment, the circuit board 10 is a ceramic board. The circuit board 10 is provided with the image sensor 20 and an electrical connector 15 for realizing signal transmission between the camera module 100 and the electronic device.

[0059] The image sensor 20 includes an integrated photosensitive element (Image Sensor) and an image signal processing chip (Image Signal Processing Chip, referred to as ISP Chip), and the photosensitive element can be a charge coupled device or a complementary me...

[0069] The structure of the camera module 200 provided by the second embodiment is basically the same as that of the camera module 100 provided by the first embodiment, the difference is that in the camera module 200 provided by the second embodiment, the lens mount 230 The outer surface 401 of the receiving cylinder 234 is insert molded with a metal layer 236 , and the metal layer 236 surrounds the outer surface 401 of the receiving cylinder 234 for a week. Preferably, the metal layer 236 is an outer surface 401 located below the glue container 101 and corresponding to the internal thread 344 . The metal layer 236 is used to strengthen the strength of the mirror base 230, and the metal layer 236 surrounds the outer surface of the mirror base 30 for a week, which can prevent the receiving tube 234 from cracking due to uneven force when the lens barrel and the mirror base 230 are screwed together. open or crack.

Abstract

A camera module comprises a lens base and a lens barrel. The lens base comprises a receiving barrel. The inner surface of the receiving barrel is provided with an internal thread. The lens barrel is provided with an external thread matched with the internal thread. The camera module is characterized in that the end, facing the lens base, of the lens barrel is provided with a ring groove; an elastic ring is arranged in the ring groove; the outer diameter of the elastic ring sleeved in the ring groove is larger than the outer diameter of the external thread of the lens barrel; the lens barrel isarranged in the receiving barrel; and the elastic ring is clamped between the ring groove and the internal thread.

Description

technical field [0001] The invention relates to a camera module. Background technique [0002] The camera module usually includes a lens barrel and a lens base, and the lens barrel and the lens base are screwed together. Due to the limitation of processing accuracy and material, during debugging, the torque between the lens barrel and the lens base will appear torsion jump, torque mutation and other torque unevenness. The phenomenon of uneven torque can easily lead to complete focus adjustment. When dispensing glue, the lens barrel cannot be accurately fixed to the optimal position of the desired image, resulting in out-of-focus, which affects the analysis and performance of the camera module, resulting in reduced yield and increased production costs. [0003] Therefore, it is necessary to provide a camera module capable of overcoming the above technical problems. Contents of the invention [0004] The purpose of the present invention is to provide a camera module that c...
