the third lens group comprises at least one third lens and a third lens base for bearing the third lens, and the second lens base is connected with the third lens base in a sliding manner;
and the photosensitive assembly is arranged at the image side of the third lens group.
2. The camera module of claim 1, wherein the second driving member comprises two coil sets, one of the coil sets is connected to the second lens set, the other coil set is connected to the third lens set, and when a current is applied to the two coil sets, an attractive force or a repulsive force is generated between the two coil sets to drive the third lens holder to approach or depart from the second lens set along the optical axis.
3. The camera module of claim 2, wherein the first driving member comprises a piezoelectric rod disposed on the first lens holder and connected to the second lens holder, the piezoelectric rod being configured to drive the second lens holder to slide along the optical axis.
4. The camera module of claim 3, wherein the camera module further comprises:
the electromagnetic piece is arranged on the third lens base so as to generate a magnetic field after the coil assembly is electrified;
the position sensing piece is arranged on one side, close to the second mirror base, of the first mirror base so as to sense the position, relative to the first mirror base, of the second mirror base.
5. The camera module of claim 1, wherein the second driving member comprises a piezoelectric rod, the piezoelectric rod is disposed on the second lens holder and connected to the third lens holder, and the piezoelectric rod is configured to drive the third lens holder to slide along the optical axis.
6. The camera module according to claim 5, further comprising a guide rail disposed on the first lens holder and arranged along the optical axis, wherein the second lens holder is slidably connected to the guide rail;
the first driving piece comprises a magnetic piece and a coil group, the magnetic piece is arranged on one side opposite to the first mirror base, the coil group is arranged on one side opposite to the second mirror base, one coil group corresponds to one magnetic piece, a magnetic field is generated after current is introduced into the coil group, and the magnetic piece and the coil group generate attraction or repulsion force so as to drive the second mirror base to slide along the guide rail.
7. The camera module of claim 6, further comprising a position sensor disposed on the second lens holder for sensing a position of the second lens holder relative to the first lens group.
8. The camera module of any of claims 1-7, further comprising a light redirecting element disposed on an object side of the first lens group.
9. The camera module of claim 8, wherein the light redirecting element is a planar element or a prismatic element.
10. An electronic device comprising the camera module according to any one of claims 1 to 9.
