Or the mounting groove 10 may be a non-closed loop annular structure, when the structure of the mounting groove 10 is the non-closed loop annular structure, the number of the mounting grooves 10 in a group of mounting grooves 10 may not need to be considered, as long as there are mounting grooves 10 corresponding to the blind holes 23 provided on the fixing frame 21. Therefore, the opening form of the mounting groove 10 is not limited in this embodiment as long as the adjusting member 3 can extend into the blind hole 23 through the mounting groove 10.
In this embodiment, the adjusting member 3 passes through the mounting groove 10 and can be fitted on the mounting groove 10, i.e., the adjusting member 3 functions to connect the lens barrel 1 and the lens group 2.

The fixing portion 32 is used to connect the fixing frame 21 and the adjusting portion 31, for example, the fixing frame 21 and the adjusting portion 31 may be connected by an elastic component (spring) or by a snap-fit connection, or the fixing portion 32 is embedded in the adjusting portion 31.
The fixing portion 32 is used for connecting the fixing frame 21 and the adjusting portion 31, and the adjusting portion 31 is only disposed in the blind hole 23 and is not connected to the blind hole 23, that is, the adjusting portion 31 is not connected to the fixing frame 21. When the fixing portion 32 connects the fixing frame 21 and the adjusting portion 31 together, the lens barrel 1 and the lens group 2 are connected together. When the fixing portion 32 does not connect the fixing frame 21 and the adjusting portion 31 together, and the lens barrel 1 and the lens group 2 are not connected together at this time, the lens group 2 is movable relative to the lens barrel 1, and the adjusting gap 4 between the adjusting portion 31 and the bottom surface 231 of the blind hole 23 can be adjusted, that is, the setting position of the lens group 2 can be adjusted, so as to adjust the eccentricity of the lens group 2.

In this embodiment, the adjusting member 3 drives the lens group 2 to slide in the curved groove, and due to the structural limitation of the curved groove, the lens group 2 can move spirally, that is, along the circumferential direction of the lens barrel 1, and simultaneously move along the axial direction of the lens barrel 1, so that the position of the lens group 2 in the axial direction of the lens barrel 1 can be adjusted. For example, when the eccentricity problem of the lens group 2 is solved, the eccentricity problem of the lens group 2 can be solved by the circumferential movement, the radial movement and the axial movement of the lens group 2 so as to change the setting position of the lens group 2 in the lens barrel 1.
In one embodiment, referring to fig. 3 and 5, the side wall of the curved groove is an inclined side wall 101, and the adjusting part 31 of the adjusting member 3 has an inclined side 311, and the inclined side 311 is attached to the inclined side wall 101.
In this embodiment, the sidewall configuration of the curved slot is defined, and the configuration of the adjustment portion 31 of the adjustment member 3 is defined so that the curved slot and the adjustment member 3 can mate, and in addition, facilitate the sliding of the adjustment member 3 within the curved slot.
In a specific embodiment, referring to fig. 5, the adjusting member 3 is a guide shaft including a first shaft, a second shaft and a third shaft, wherein the first shaft, the second shaft and the third shaft are integrally formed. The first shaft and the third shaft are cylindrical shafts, the second shaft is a circular truncated cone shaft, and the side portion of the circular truncated cone shaft is an inclined side portion 311. In use, the side of the shaft of the circular truncated cone engages the side wall of the curved slot, the third shaft extends into the blind hole 23, and the first shaft may be set up on the curved slot, for example, the diameter of the first shaft may be slightly larger than the inner diameter of the curved slot.
In one embodiment, referring to fig. 6, at least three blind holes 23 are uniformly distributed on the fixing frame 21.
In this embodiment, at least three blind holes 23 are disposed at equal intervals in the circumferential direction of the fixing frame 21, so that the connecting force of the adjusting member 3 to the lens group 2 acts on the lens group 2 uniformly, which can be fixed on the lens barrel 1 firmly on the basis of ensuring that the lens group 2 can adjust the position.
In a second aspect, an electronic device is provided. The electronic equipment comprises the lens module according to the first aspect.
In this embodiment, an electronic device is provided. The lens module is applied to electronic equipment, and the eccentricity of the lens module of the electronic equipment can be conveniently adjusted. The electronic device may be, for example, an image pickup device or a projection device.
In the above embodiments, the differences between the embodiments are described in emphasis, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in consideration of brevity of the text.
Although some specific embodiments of the present invention have been described in detail by way of illustration, it should be understood by those skilled in the art that the above illustration is only for the purpose of illustration and is not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
