Thus, when the first driving mechanism 30 drives the sensing module 10 to move to different positions, different first lens groups 12 may form different imaging lens groups with the second lens group 21 of the lens 20 to realize different shooting functions, that is, the plurality of different sensors 11 and the first lens groups 12 may share one second lens group 21 to form different imaging lens groups to realize different shooting functions, and each image sensor 11 does not need to set up an individual lens 20 to realize the shooting function, and does not need to set up a plurality of holes to correspond to different cameras, thereby improving the aesthetic feeling of appearance.

It will be appreciated that, referring to fig. 4, the guide rail 40 includes two guide portions symmetrically disposed with the bracket 13 disposed therebetween, each of which is formed with the first guide groove 42 and the second guide groove 43 described above.

Referring to fig. 4-6 and fig. 9, when the bracket 13 is at the first position a, the first protrusion 1321 is located in the second position-limiting section 423 and abuts against one end of the second position-limiting section 423 close to the second guide slot 43, and the second protrusion 1331 is located in the fourth position-limiting section 433;

referring to fig. 4 and fig. 7-9, when the bracket 13 is at the second position B, the first protrusion 1321 is located in the first position-limiting section 422, and the second protrusion 1331 is located in the third position-limiting section 432 and abuts against an end of the third position-limiting section 432 close to the first guide slot 42.

In this way, during the process that the bracket 13 moves from the second position B to the first position a, the first protrusion 1321 may enter into the second position-limiting section 423 and abut against one end of the second position-limiting section 423, so that the bracket 13 is located at the first position a to ensure that the first lens group 12 on the first mounting portion 132 is aligned with the second lens group 21, and conversely, during the process that the bracket 13 moves from the first position a to the second position B, the second protrusion 1331 may enter into the third position-limiting section 432 and abut against one end of the third position-limiting section 432, so that the bracket 13 is located at the second position B to ensure that the first lens group 12 on the second mounting portion 133 is aligned with the second lens group 21.

Specifically, referring to fig. 9, in such an embodiment, the first position-limiting section 422 and the second position-limiting section 423 are both bent upward relative to the first guiding section 421 and are connected by an arc transition, and the third position-limiting section 432 and the fourth position-limiting section 433 are also both bent upward relative to the second guiding section 431 and are connected by an arc transition.

When the bracket 13 needs to be moved to the second position B, the first driving mechanism 30 drives the bracket 13 to move, so that the first protrusion 1321 gradually disengages from the second limiting section 423 and slides into the first guiding section 421, and meanwhile, the second protrusion 1331 also gradually disengages from the fourth limiting section 433 and slides into the second guiding section 431, in the process, the bracket 13 first descends by a height, so that the first lens group 12 on the first mounting portion 132 is gradually separated from the lens 20 to prevent the first lens group 12 from being damaged due to excessive friction between the first lens group 12 and the lens 20 in the moving process. Subsequently, the first protrusion 1321 gradually slides into the first limiting section 422, and the second protrusion 1331 slides into the third limiting section 432, in this process, the height of the bracket 13 gradually rises, so that the first lens group 12 on the second mounting portion 133 gradually fits to the lens 20, and when the second protrusion 1331 abuts against the limit position of the third limiting section 432, the first lens group 12 on the second mounting portion 133 aligns to the second lens group 21 of the lens 20, that is, the state shown in fig. 6 is moved to the state shown in fig. 8.

It is understood that when it is desired to move from the second position B to the first position a, the principle is substantially the same as the above-mentioned principle of moving from the first position a to the second position B, and the description is not repeated herein.

Specifically, it is understood that in some embodiments, in order to achieve different image capturing functions, such as telephoto capturing and wide-angle capturing, the number and thickness of the lenses of the first lens group 12 may have a certain difference, and when the sensing module 10 translates, there may be a difference in height of the first lens group 12 and a motion interference with the second lens group 21, so in this embodiment, the second driving mechanism 50 may drive the second lens group 21 to move along the optical axis direction of the lens 20 to prevent the first lens group 12 with different height from interfering with the second lens group 21 during the motion.

Further, referring to fig. 4, 6 and 8, in some embodiments, the lens barrel 20 further includes a lens barrel 22 and a sleeve 23, the second lens group 21 is mounted in the lens barrel 22, the lens barrel 22 is mounted in the sleeve 23 and is in threaded connection with the sleeve 23, and the second driving mechanism 50 is configured to drive the lens barrel 22 to rotate in the sleeve 23 so that the lens barrel 22 moves relative to the sleeve 23 along the optical axis direction of the lens barrel 20.
