It can be appreciated that the detachable connection of the housing 40 of the lens 10 and the lens mount 50 is achieved by rotating the housing 40, so that the detachment of the housing 40 of the lens 10, the optical assembly 20, and the driving assembly 30 is simple. Particularly, because the first side wall structure 422 of the housing 40 is also in a circular ring shape, the overall size is small, the user can conveniently rotate and detach the housing, and the user experience and the product competitiveness can be improved.

Specifically, in the housing 40, the base 44 includes a bottom plate 442 and an extending wall 444, the bottom plate 442 is used for carrying the coil 32 and/or the housing 24 and is connected and fixed with the first sidewall structure 422, the bottom plate 442 has a light-passing opening 442a corresponding to the lens assembly 22, the extending wall 444 is connected and annularly disposed on a side of the bottom plate 442 away from the coil 32 and/or the optical assembly 20, the detachable structure 48 may include a first snap-fit member 482 disposed on an outer side of the extending wall 444, the lens mount 50 includes an annularly disposed second sidewall structure 52, a second snap-fit member 54 disposed on an inner side of the second sidewall structure 52, and a base plate 56 connected to an inner side of an end of the second sidewall structure 52 away from the base 44, the base plate 56 has an opening 562, and the opening 562 may allow the object-side light provided by the optical assembly 20 to pass through and be provided to the image sensor.

Particularly, because the first side wall structure 422 of the housing 40 is also in a circular ring shape, the overall size is small, the user can conveniently rotate and detach the housing, and the user experience and the product competitiveness can be improved.

Specifically, the first locking member 482 may include one of a latch and a catch, the second locking member 54 may include the other of the latch and the catch, in this embodiment, the first locking member 482 may be a catch disposed outside the extension wall 444, the catch may include a guide portion and a locking portion communicating with the guide portion, and the second locking member 54 may include a latch.

In particular, the second resilient member 364 may include a third portion 364a and a fourth portion 364b, the third portion 364a connecting the coil 32 and/or the side of the housing 24 remote from the base 44, and the fourth portion 364b connecting between the third portion 364a and the first sidewall structure 422. In this embodiment, the third portion 364a may be annular, and may be disposed on a side surface of the housing 24 away from the base 44, for example, the third portion 364a may be fixed on a side surface of the housing 24 away from the base 44 by glue or other fixing members, the number of the fourth portions 364b may be set as required, for example, the number of the fourth portions 364b may be plural, and the plural fourth portions 364b may be connected to an outer edge of the third portion 364a at uniform intervals, and an end of each fourth portion 364b away from the third portion 364a may abut against the first sidewall structure 422, for example, the extending plate 424 of the first sidewall structure 422. The plurality of fourth portions 364b is the same number as the plurality of second portions 362b and is positioned opposite thereto. In the present embodiment, the number of the fourth portions 364b is mainly illustrated as four. Wherein, four fourth portions 364b may be respectively connected to four sides of the third portion 364 a. Each of the fourth portions 364b may include two second elastic sub-portions 364c connected in parallel to the third portion 364a and spaced apart from each other.

Specifically, the second elastic member 364 may also be a metal sheet structure, but is not limited to the above, and may also be a spring or other elastic structure. When the third portion 364a is moved by the coil 32 and the housing 24, at least a portion (e.g., the fourth portion 364b) of the second elastic member 364 can be deformed, and when the coil 32 is powered off, at least a portion (e.g., the fourth portion 364b) of the second elastic member 364 can be deformed again to release the elastic force, so that the coil 32 and the housing 24 are reset.

The electrical connector 46 may be embedded in the base 44, and both ends thereof are exposed from the surface of the base 44, for example, one end of the electrical connector 46 is exposed from the lower portion of the base 44 to receive an external electrical signal, and the other end 464 of the electrical connector 46 is exposed from the upper surface of the base 44 and connected to the second portion 362b of the first elastic member 362. Wherein the other end 464 of the electrical connector 46 and the second portion 362b of the first elastic member 362 can be connected by soldering or by conductive adhesive. It is understood that the electrical connector 46 may be a conductive trace, a conductive cable, a conductive metal strip, a conductive metal sheet, etc., and the electrical connector 46 may be formed on the housing 40 (e.g., the base 44) by integral molding, gluing, printing, etc. to provide power to the coil 32 through the housing 40 (e.g., the base 44), the spring 36, etc.

Further, the number of the electrical connectors 46 may be set according to actual needs, and specifically may be 2 to 4, in this embodiment, the number of the electrical connectors 46 is mainly illustrated as two, and one end of each of the two electrical connectors 46 may be exposed from the extension wall 444 of the base 44. The other ends 464 of the two electrical connectors 46 may be oppositely disposed and respectively connected to the two oppositely disposed second portions 362b, so as to respectively electrically connect both ends of the first elastic member 362 to supply power to the coil 32 via the first elastic member 362.

Specifically, one end 462 of the electrical connector 46 is a first contact portion, the lens mount 50 is further provided with a second contact portion 58, and when the housing 40 of the lens 10 is mounted on the lens mount 50, the first contact portion 462 can contact and conduct with the second contact portion 58, so that the lens mount 50 supplies power to the coil 32 via the electrical connector 46. It can be understood that when the housing 40 of the lens 10 is mounted on the lens mount 50, the first contact portion 462 is in contact conduction with the second contact portion 58, so that the lens mount 50 can supply power to the coil 32 through the electrical connector 462 on the base 44, thereby ensuring the normal operation of the coil 32, and in addition, the contact conduction mode has no cable constraint, thereby avoiding the cable from influencing the detachment of the lens 10, and the volume of the lens 10 is not increased, and the safety is higher. In addition, the first contact portion 462 of the electrical connection 46 may be a spring-loaded pin, which is capable of being pressed against the second contact portion 58 to ensure the stability of the electrical connection.
