[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] like Figures 1-3 As shown, this utility model provides a lens module, including: a main camera lens 1; an auxiliary camera lens group 2, the auxiliary camera lens group 2 including multiple auxiliary cameras; a rotating mechanism 3, the rotating mechanism 3 being able to selectively rotate one of the multiple auxiliary cameras to a position coinciding with the optical axis of the main camera lens 1 to cooperate with the main camera lens 1 to form a composite lens; and a camera chip 4, the camera chip 4 being used to process the light beam collected by the main camera lens 1 or the composite lens.

[0029] Specifically, in the initial state, the main camera lens 1, as a set of fixed lenses, has an initial focal length with the camera chip. It independently guides external light and projects the light onto the camera chip 4. The camera chip 4 converts the light signal into an electrical signal to generate a digital image, enabling the lens module to function as a main camera. Further, the operator uses the rotating mechanism 3 to rotate one of the auxiliary lenses in the auxiliary lens group 2 to a position aligning with the optical axis of the main camera lens 1. This auxiliary lens, as a set of movable lenses, together with the fixed lenses of the main camera lens 1, forms a composite lens. Therefore, the composite lens group includes a set of fixed lenses and a set of movable lenses, allowing the composite lens to have a combined focal length different from the initial focal length. By switching different auxiliary lenses to change the combined focal length of the composite lens, different shooting functions such as telephoto and wide-angle can be achieved. The camera chip 4 is a CMOS chip capable of matching multiple lenses, and the auxiliary lens group 2 can be categorized into telephoto lenses, wide-angle lenses, macro lenses, or zoom lenses, depending on the shooting function.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the rotating mechanism 3 includes a rotating motor 301 and a rotating shaft 302 connected to the rotating motor 301. The rotating shaft 302 is parallel to the optical axis of the main camera lens 1, and multiple auxiliary cameras are mounted on the rotating shaft 302.

[0031] Specifically, multiple auxiliary lenses in the auxiliary lens group 2 are installed at intervals around the axial direction of the rotation shaft 302. During the rotation of the rotation shaft 302 driven by the rotation motor 301, the multiple auxiliary lenses can sequentially pass through the optical axis of the main lens 1 to form a composite lens with different focal lengths. To facilitate the switching of the auxiliary lenses, in some embodiments, the multiple auxiliary lenses are evenly installed around the axial direction of the rotation shaft 302, and the rotation angle of the rotation shaft 302 is the same each time it is switched, to ensure that the optical axes of the auxiliary lenses and the main lens 1 can be precisely aligned, avoiding image blurring. The rotation motor 301 here can be a servo motor or a stepper motor.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the auxiliary camera lens is fixedly connected to the rotating shaft 302 via a connecting handle 203 perpendicular to the axis of the rotating shaft 302. One end of the connecting handle 203 is fixedly connected to the auxiliary camera lens, and the other end is provided with a connecting ring sleeved on the outer periphery of the rotating shaft 302. Multiple auxiliary cameras are installed at intervals along the axial direction of the rotating shaft 302 via the connecting handle 203. The multiple auxiliary cameras are independent of each other, which facilitates the replacement or addition of auxiliary cameras.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the rotating motor 301 is a two-speed stepper motor, and the auxiliary camera lens group 2 includes a first auxiliary camera lens 201 and a second auxiliary camera lens 202.

[0034] Specifically, the two-stage stepper motor refers to a stepper motor that can rotate to two designated positions after startup. When the two-stage stepper motor is not started, both the first auxiliary lens 201 and the second auxiliary lens 202 are in positions that do not obstruct light from entering the main lens 1, and the main lens 1 guides the light beam independently. When the two-stage stepper motor rotates to the first fixed position, the optical axis of the first auxiliary lens 201 coincides with that of the main lens 1, cooperating with the main lens 1 to guide the light beam. When the two-stage stepper motor rotates to the second fixed position, the optical axis of the second auxiliary lens 202 coincides with that of the main lens 1, cooperating with the main lens 1 to guide the light beam. By utilizing the designated rotation angles of the two-stage stepper motor, precise alignment of the optical axes of the auxiliary lens and the main lens 1 is achieved, effectively improving the imaging clarity of the lens module.

[0035] In other embodiments, the rotating motor 301 may also be a stepper motor with multiple rotation positions. The multiple positions include at least a gap that allows light to enter only the main camera lens 1 and multiple different positions that correspond to multiple auxiliary cameras aligning with the optical axis of the main camera lens 1. In addition, the auxiliary camera lens group may also include other numbers of auxiliary cameras to achieve more shooting effects as needed.

[0036] In some embodiments, the first auxiliary lens 201 is a telephoto lens, and the second auxiliary lens 202 is an ultra-wide-angle lens.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the lens module further includes a lens mount 5 for mounting the main camera lens 1, and the camera chip 4 is fixedly mounted inside the lens mount 5 with the center of the camera chip 4 coinciding with the optical axis of the main camera lens 1.

[0038] Specifically, the lens mount 5 is used to support the main camera lens 1 and can be connected to an electronic device. The camera chip 4 is installed inside the lens mount 5 perpendicular to the optical axis of the main camera lens 1 to receive the light beam guided by the main camera lens 1 or the composite lens and process it to generate image data.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the lens mount 5 is fixed with a motor mounting platform 303 for placing the rotating motor 301 on the radially outer side of the optical axis of the main camera lens 1.

[0040] Specifically, to improve the stability of the lens module connected to the electronic device, the bottom surface of the motor mounting platform 303 is coplanar with the bottom surface of the lens mount 5, increasing the connection area between the lens module and the electronic device. The rotating motor 301 is mounted on the top surface of the motor mounting platform 303. In other embodiments, the rotating motor 301 can also be directly fixed to the side of the lens mount 5.

[0041] like Figure 3 As shown, in some embodiments, a PCB board 6 is mounted on the bottom of the lens mount 5, and the camera chip 4 is soldered and fixed to the PCB board 6.

[0042] Specifically, the camera chip 4 is used to convert the light signal guided by the lens into an electrical signal and output the raw image data, while the PCB board 6 is used to provide power support and a signal transmission path for the camera chip 4. Since the camera chip 4 and the PCB board 6 have different coefficients of thermal expansion, the weld seam is prone to cracking at high temperatures. To ensure the stability of the welded connection between the two, in some embodiments, stress relief holes can be provided on the PCB board 6 surrounding the camera chip 4.

[0043] like Figure 3 As shown, in some embodiments, the PCB board 6 is provided with a connector 7 for connecting electronic devices.

[0044] Specifically, the end of connector 7 furthest from PCB board 6 is used to connect to the standard interface of electronic device. The raw image data generated by camera chip 4 can be transmitted to electronic device for display through the signal transmission path on PCB board and connector 7.

[0045] This invention also provides an electronic device equipped with the aforementioned lens module. The main camera lens 1, with its initial focal length, enables the electronic device to perform basic main camera functions. A rotating mechanism 3 rotates different auxiliary lenses in the auxiliary lens group 2 to positions coinciding with the optical axis of the main camera lens 1, forming composite lenses with different combined focal lengths. A camera chip 4 then processes the collected light beams to create images, enabling the electronic device to perform various shooting functions. This electronic device can be a drone, mobile phone, or surveillance camera, among other common electronic devices. This design effectively reduces the number of openings in the electronic device's casing and the number of internal chips, improving the overall aesthetics of the electronic device and significantly reducing hardware costs.
