Referring to fig. 3, the image sensor 15 is disposed on the first board 111 of the circuit board 11, the image sensor 15 is accommodated in the first accommodating groove 1251, and the image sensor 15 corresponds to the optical filter 16 disposed on the bracket 12. That is, the image sensor 15 is opposite to the lens 14, and the filter 16 is located between the image sensor 15 and the lens 14, so that the light entering the lens 14 finally reaches the image sensor 15 through the filter 16.

Referring to fig. 2 and fig. 3, the filter 16 is disposed between the lens 14 and the image sensor 15, and the filter 16 is carried on the supporting portion 1252 of the bracket 12. The filter 16 may be an IR pass filter 16, an IR cut filter 16, or the like, and different types of filters 16 may be used according to the actual application. For example, when the camera module 10 uses the IR pass filter 16, only infrared rays are allowed to pass through the filter 16 to the image sensor 15, and the camera module 10 acquires an infrared image which can be used for iris recognition, or depth information as a structured light image for structured light distance measurement, or 3D modeling together with a visible light image, or binocular distance measurement, etc. When the camera module 10 uses the IR cut filter 16, the infrared light is not allowed to pass through the filter 16, but the visible light is allowed to pass through the filter 16 to the image sensor 15, and the image obtained by the camera module 10 is a visible light image, which can be used as a general shooting requirement.

Specifically, the fixed cylinder 131 includes a receiving cavity 1312, and a top wall 1311 and a bottom wall 1313 disposed opposite to each other. The receiving cavity 1312 extends through the top wall 1311 and the bottom wall 1313, and the bottom wall 1313 is carried on the second surface 122 of the bracket 12. The accommodating cavity 1312 is used for accommodating the movable cylinder 132, and the inner side surface of the accommodating cavity 1312 is provided with the second driving member 134.

The movable cylinder 132 is accommodated in the accommodating chamber 1312 of the fixed cylinder 131, and the shape of the movable cylinder 132 matches the shape of the accommodating chamber 1312. A first driving member 133 is provided on an outer side surface of the movable cylinder 132. The movable cylinder 132 is movable relative to the fixed cylinder 131 by interaction of the first and second drivers 133 and 134.

In some embodiments, the first driver 133 is a coil and the second driver 134 is a permanent magnet. Specifically, a plurality of permanent magnets (not shown) are disposed on an inner side surface of the accommodating cavity 1312 of the fixed cylinder 131 to generate a magnetic field in the accommodating cavity 1312, and a coil (not shown) is wound on an outer side surface of the movable cylinder 132. When the coil is powered on, the driving force generated by the permanent magnet and the coil can drive the coil to drive the movable cylinder 132 to move along the optical axis O, so as to drive the lens 14 to move along the optical axis O, thereby realizing automatic focusing or zooming.

It should be noted that the first driving member 133 may also be a permanent magnet, and in this case, the second driving member 134 is a coil. That is, the inner side surface of the fixed cylinder 131 is provided with a coil (not shown); a plurality of permanent magnets (not shown) are provided on an outer side surface of the movable cylinder 132 to generate a magnetic field outside the movable cylinder 132. When the coil is powered on, the driving force generated by the permanent magnet and the coil can drive the coil to drive the movable cylinder 132 to move along the optical axis O, so as to drive the lens 14 to move along the optical axis O, thereby realizing automatic focusing or zooming.

The through hole 1363 corresponds to the top of the movable cylinder 132 such that the top of the movable cylinder 132 is inserted into the through hole 1363. When the movable cylinder 132 abuts against the second resilient piece 136, the movable portion 1362 applies a force to the movable cylinder 132 along the top wall 1311 and in the direction from the bottom wall 1313, so that the movable cylinder 132 cannot be disengaged from the fixed cylinder 131. The structure of the first resilient tab 135 is the same as that of the second resilient tab 136, and the connection manner of the first resilient tab 135 to the bottom of the movable tube 132 is the same as that of the second resilient tab 136 to the top of the movable tube 132, which will not be described in detail herein.

Referring to fig. 4, the present application further provides an electronic device 100.

Since at least opposite sides of the bracket 12 of the camera module 10 protrude from corresponding sides of the circuit board 11, when the camera module 10 is mounted in the mounting hole 213 of the first housing 20, the mounting position of the camera module 10 can be determined by the first surface 121 of the portion of the bracket 12 protruding from the first plate 111 colliding with the stepped surface 2132 in the mounting hole 213. Moreover, since the side 123 of the portion of the bracket 12 protruding relative to the first plate 111 abuts against the inner side of the second cavity 2133, the camera module 10 cannot move in the direction perpendicular to the optical axis O of the camera module 10 in the mounting hole 213 while the mounting position of the camera module 10 is defined, so that the position of the camera module 10 is more stable.
