[0086] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0087] In the related art, the anti-shake of telephoto lens assemblies usually adopts the following two methods: 1+2 scheme, that is, the optical element controls one axis of anti-shake, and the lens controls AF (auto focus) and the other axis of anti-shake; and 2+1 scheme, that is, the optical element controls two axes of anti-shake, and the lens only controls AF (auto focus). In both methods, optical elements are involved in anti-shake, that is, the refraction direction of light is changed by twisting the optical element to achieve anti-shake. In a telephoto lens assembly, the optical path of light from the optical element to the imaging element is relatively long. Therefore, even if a small angle error occurs in the optical element at the front end during the twisting process, when the light is refracted and hits the imaging element at the rear end, a large offset will occur at the rear end. Therefore, the anti-shake effect of changing the refraction direction of light by twisting the optical element is poor.

[0088] In order to solve the above technical problems, the present disclosure provides a lens assembly and an electronic device.

[0089] According to a first aspect of an embodiment of the present disclosure, a lens assembly is provided, such as Figure 1 , Figure 2 and Figure 3 As shown, the lens assembly includes: a lens barrel 1, which is used to install the lens; a first mounting part 2, a second mounting part 3 and a third mounting part 4, and the lens barrel 1, the first mounting part 2, the second mounting part 3 and the third mounting part 4 are movably connected in sequence; a driving unit 5, which is used to drive the lens barrel 1, the first mounting part 2 and the second mounting part 3 to move along the first axis, the second axis and the third axis respectively; wherein the first axis, the second axis and the third axis are respectively arranged along different directions.

[0090] The lens barrel 1 is provided to provide a mounting base for the lens, and the third mounting portion 4 is used to mount the lens assembly of the embodiment of the present disclosure on an adapted electronic device or optical device; the lens barrel 1, the first mounting portion 2, the second mounting portion 3 and the third mounting portion 4 are connected in sequence, and when anti-shake control is performed, the lens barrel 1, the first mounting portion 2 and the second mounting portion 3 are controlled by the driving unit 5 to move along the first axis, the second axis and the third axis respectively, thereby driving the lens disposed on the lens barrel 1 to move along the first axis, the second axis and the third axis to achieve anti-shake, that is, during the displacement process, the lens will not change the angle between its optical axis and the imaging element 7, that is, the incident angle of the light on the imaging element 7 will not be changed. Compared with the anti-shake method of changing the refraction direction of the light by twisting the optical element 6, the present disclosure effectively improves the accuracy of light adjustment, thereby improving the anti-shake effect.
