[0030] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: since the camera lens includes a first lens group, a second lens group and a third lens group, and M lenses in the first lens group are aspherical lenses, N lenses in the second lens group are aspherical lenses, and L lenses in the third lens group are aspherical lenses, that is, all lenses in the camera lens are aspherical lenses, therefore, the thickness of the camera lens can be reduced.

In the second lens group, N lenses are fixed in the second inner barrel, the outer wall of the second inner barrel is closer to the optical axis than the inner wall of the first outer barrel, and the second lens group can move relative to the first outer barrel, that is, the second lens group can move along the optical axis toward the image side or beyond the object side. In the third lens group, L lenses are fixed in the third inner barrel, and the outer wall of the third inner barrel is closer to the optical axis than the inner wall of the first outer barrel. Close to the optical axis, the third lens group can be moved relative to the first outer barrel, that is, the third lens group can be moved along the optical axis toward the image side or beyond the object side, and the second outer barrel can be moved relative to the first outer barrel, that is, the second outer barrel can be moved along the optical axis toward the image side or beyond the object side relative to the first outer barrel. In this way, when the camera lens is in a non-imaging state, the first lens group can be moved along the optical axis toward the image side, the second lens group can be moved along the optical axis toward the image side, the third lens group can be moved along the optical axis toward the image side, and the second outer barrel can be moved along the optical axis toward the image side relative to the first outer barrel, thereby making the first lens group, the second lens group, the third lens group, the first outer barrel and the second outer barrel tightly gathered together, reducing the thickness of the camera lens when it is in a non-imaging state, and facilitating the integration of the camera lens into an electronic device. In summary, the technical solution provided by the present disclosure can improve the structure of the camera lens so as to facilitate the integration of the camera lens into an electronic device.

[0031] Moreover, the camera device is assembled in the mounting hole of the equipment body. When the camera device is in a non-imaging state, the surface of the camera device facing the object side is basically flush with the surface of the equipment body facing the object side. Since the camera device can be stored in the mounting hole when the camera device is in a non-imaging state, it is convenient to integrate the camera device into the electronic device.

[0051] In this embodiment, a first guide rail is provided on the outer wall of the first inner lens barrel 13, and a second guide rail is provided on the inner wall of the second outer lens barrel 6. The first end of the first slider 61 cooperates with the first guide rail, and the first driving mechanism is configured to drive the first slider to move along the first guide rail.

[0054] In this embodiment, the first slider 61 is driven by the first driving mechanism and the second driving mechanism to move the first lens group 1 relative to the second outer barrel 6, and the first driving mechanism and the second driving mechanism can control the relative positions of the first lens group 1 and the second outer barrel 6 by the first voltage value and the second voltage value.

[0055] In this embodiment, a third guide rail is provided on the outer wall of the second inner lens barrel 23, and a fourth guide rail is provided on the inner wall of the first outer lens barrel 5. The first end of the second slider 52 cooperates with the third guide rail, and the third driving mechanism is configured to drive the second slider to move along the third guide rail.

[0056] In this embodiment, the third and fourth guide rails can be grooved guide rails, and the second slider 52 can be a slider. Of course, the third and fourth guide rails can also be convex guide rails.

The third drive mechanism can control the third movement distance of the second slider 52 along the third guide rail by controlling a third voltage value, and the fourth drive mechanism can control the fourth movement distance of the second slider 52 along the fourth guide rail by controlling a fourth voltage value.

[0058] In this embodiment, the second slider 52 is driven by the third driving mechanism and the fourth driving mechanism to move the second lens group 2 relative to the first outer barrel 5, and the third driving mechanism and the fourth driving mechanism can control the relative position of the second lens group 2 and the first outer barrel 5 by the third voltage value and the fourth voltage value.

The second end of the third slider 53 cooperates with the fourth guide rail, and the sixth driving mechanism is configured to drive the third slider 53 to move along the fourth guide rail. For example, the sixth driving mechanism can drive the third slider 53 to move along the fourth guide rail toward the image side or toward the object side.

[0060] In this embodiment, the fifth guide rail can be a grooved guide rail, and the third slider 53 can be a slider. Of course, the fifth guide rail can also be a convex guide rail. The first end of the third slider 53 is provided with a fifth groove that mates with the fifth guide rail, and the raised portion of the fifth guide rail is located in the fifth groove. The second end of the third slider 53 is provided with a sixth groove that mates with the fourth guide rail, and the raised portion of the fourth guide rail is located in the sixth groove.

[0061] In this embodiment, the fifth and sixth drive mechanisms are piezoelectric ceramic motors. The fifth drive mechanism can control the fifth movement distance of the third slider 53 along the fifth guide rail by controlling a fifth voltage value, and the sixth drive mechanism can control the sixth movement distance of the third slider 53 along the fourth guide rail by controlling a sixth voltage value.

[0062] In this embodiment, the third slider 53 is driven by the fifth driving mechanism and the sixth driving mechanism to move the third lens group 3 relative to the first outer barrel 5, and the fifth driving mechanism and the sixth driving mechanism can control the relative position of the third lens group 3 and the first outer barrel 5 by the fifth voltage value and the sixth voltage value.

[0063] It should be noted that, in this embodiment, a guide rail, i.e., a fourth guide rail, is provided on the inner wall of the first outer lens barrel 5, and the second slider 52 and the third slider 53 can share the fourth guide rail. In other embodiments, two guide rails can be provided on the inner wall of the first outer lens barrel 5, and the second slider 52 and the third slider 53 can each use one guide rail.

[0064] In the present embodiment, the outer wall of the first outer lens barrel 5 is provided with a sixth guide rail, the first end of the fourth slider 56 cooperates with the sixth guide rail, and the seventh driving mechanism is configured to drive the fourth slider 56 to move along the sixth guide rail. For example, the seventh driving mechanism can drive the fourth slider 56 to move toward the image side or to the object side along the sixth guide rail. The second end of the fourth slider 56 cooperates with the second guide rail, and the eighth driving mechanism is configured to drive the fourth slider 56 to move along the second guide rail. For example, the eighth driving mechanism can drive the fourth slider 56 to move toward the image side or to the object side along the second guide rail.

[0065] In this embodiment, the sixth guide rail can be a grooved guide rail, and the fourth slider 56 can be a slider. Of course, the sixth guide rail can also be a convex guide rail. The first end of the fourth slider 56 is provided with a seventh groove that mates with the sixth guide rail, and the raised portion of the sixth guide rail is located in the seventh groove. The second end of the fourth slider 56 is provided with an eighth groove that mates with the second guide rail, and the raised portion of the second guide rail is located in the eighth groove.

[0066] In this embodiment, the seventh and eighth drive mechanisms are piezoelectric ceramic motors. The seventh drive mechanism can control the seventh movement distance of the fourth slider 56 along the sixth guide rail by controlling a seventh voltage value, and the eighth drive mechanism can control the eighth movement distance of the fourth slider 56 along the second guide rail by controlling an eighth voltage value.

[0067] In this embodiment, the fourth slider 56 is driven by the seventh driving mechanism and the eighth driving mechanism to move the first outer lens barrel 5 relative to the second outer lens barrel 6, and the seventh driving mechanism and the eighth driving mechanism can control the relative positions of the first outer lens barrel 5 and the second outer lens barrel 6 by the seventh voltage value and the eighth voltage value.

[0068] In this embodiment, the ninth driving mechanism 4 is movably connected to the third lens group 3 and is configured to drive the first lens group 1, the second lens group 2, and the third lens group 3 to move along the optical axis of the third lens group 3 toward the image side or toward the object side. For example, the ninth driving mechanism 4 can directly drive the third lens group 3 to move along the optical axis 9 toward the object side. Since the first lens group 1 is movably connected to the third lens group 3 via the first slider 61, the second outer barrel 6, the fourth slider 56, the first outer barrel 5, and the third slider 53, when the ninth driving mechanism 4 drives the third lens group 3 to move along the optical axis 9 toward the object side, it also indirectly drives the first lens group 1 to move along the optical axis 9 toward the object side. Since the second lens group 2 is movably connected to the third lens group 3 via the second slider 52, the first outer barrel 5, and the third slider 53, when the ninth driving mechanism 4 drives the third lens group 3 to move along the optical axis 9 toward the object side, it also indirectly drives the second lens group 2 to move along the optical axis 9 toward the object side.

[0069] In this embodiment, the ninth drive mechanism 4 is a voice coil motor that can fine-tune the positions of the first lens group 1, the second lens group 2, and the third lens group 3. The ninth drive mechanism 4 can control the ninth movement distance of the first lens group 1, the second lens group 2, and the third lens group 3 along the optical axis 9 by adjusting the current value.

[0070] It should be noted that during focusing or zooming, the movement of the third lens group 3 is smaller than that of the first lens group 1, and the movement of the third lens group 3 is also smaller than that of the second lens group 2. In other words, during focusing or zooming, the position of the third lens group 3 can be fine-tuned.

[0071] In this embodiment, if Figure 1 As shown, when the camera lens is in a non-imaging state, the first lens group 1 can be moved along the optical axis 9 toward the image side, the second lens group 2 can be moved along the optical axis 9 toward the image side, the third lens group 3 can be moved along the optical axis 9 toward the image side, and the second outer lens barrel 6 can be moved along the optical axis 9 relative to the first outer lens barrel 5 toward the image side, so that the first lens group 1, the second lens group 2, the third lens group 3, the first outer lens barrel 5 and the second outer lens barrel 6 are tightly gathered together, that is, the first lens group 1, the second lens group 2, and the third lens group 3 can be tightly gathered together by the first guide rail, the second guide rail, the third guide rail, the fourth guide rail, the fifth guide rail, and the sixth guide rail, thereby reducing the thickness of the camera lens in the non-imaging state and facilitating the integration of the camera lens into electronic equipment. Among them, there can be a gap between two adjacent lens groups in the first lens group 1, the second lens group 2, and the third lens group 3 along the optical axis 9.

[0072] In this embodiment, if Figures 2 and 3 As shown, when the camera lens is in the imaging state, or in other words, when focusing or zooming, the first lens group 1, the second lens group 2, and the third lens group 3 are driven by the corresponding driving mechanisms to move along the optical axis 9 toward the object side to a specified position. For example, Figure 2 The image shown is that the camera lens is in the imaging state of 3x optical zoom. Figure 3 The image sensor 8 is located at the image plane of the camera lens.

[0073] In this embodiment, the image sensor 8 is fixed to the end of the ninth driving mechanism 4 facing the image side.

[0074] In this embodiment, if Figure 1 As shown, when the camera device is in a non-imaging state, the thickness of the camera device along the optical axis 9 can be 9.318 mm, which is relatively small and can facilitate integration of the camera device into electronic equipment.

[0075] The embodiment of the present disclosure further provides a camera lens, which is the camera lens used by the camera device in any of the above embodiments.

[0076] The present disclosure also provides an electronic device. The electronic device may be, but is not limited to, a mobile terminal such as a smartphone, a camera, or a tablet computer. The electronic device includes a device body and a camera device according to any of the above embodiments.

[0077] In this embodiment, the device body includes a mounting hole, and the imaging device is assembled in the mounting hole. When the imaging device is in a non-imaging state, the surface of the imaging device facing the object side is substantially flush with the surface of the device body facing the object side. For example, the surface of the imaging device facing the object side may protrude from the surface of the device body facing the object side, the surface of the imaging device facing the object side may be flush with the surface of the device body facing the object side, the surface of the imaging device facing the object side may be recessed from the surface of the device body facing the object side, and the distance between the surface of the imaging device facing the object side and the surface of the device body facing the object side along the optical axis 9 is relatively small.

[0078] In this embodiment, the electronic device further includes a processor and a memory.

Of course, the imaging state of the camera device can also include the imaging state of 3.5x optical zoom, the imaging state of 4x optical zoom and other imaging states with different zoom ratios.

[0087] When the camera is in an imaging state and the electronic device receives a first control instruction for switching the camera to a non-imaging state, for example, switching from an imaging state with 5x optical zoom to a non-imaging state, this can be achieved by controlling the ninth driving mechanism 4, the first slider 61, the second slider 52, the third slider 53, and the fourth slider 56. The specific implementation process is as follows:

[0088] First, according to P04, the ninth driving mechanism 4 is controlled to return to the corresponding position.

[0089] Then, the relative positions of the third slider 53 and the third lens group 3 are controlled to return to the corresponding positions according to P053i, and the relative positions of the third slider 53 and the first outer barrel 5 are controlled to return to the corresponding positions according to P053o.

[0090] Then, the relative positions of the second slider 52 and the second lens group 2 are controlled to return to corresponding positions according to P052i, and the relative positions of the second slider 52 and the first outer barrel 5 are controlled to return to corresponding positions according to P052o.

[0091] Next, the relative positions of the fourth slider 56 and the first outer barrel 5 are controlled to return to corresponding positions according to P056i, and the relative positions of the fourth slider 56 and the second outer barrel 6 are controlled to return to corresponding positions according to P056o.

[0092] Finally, the relative positions of the first slider 61 and the first lens group 1 are restored to the corresponding positions according to P061i, and the relative positions of the first slider 61 and the second outer barrel 6 are restored to the corresponding positions according to P061o. At this point, the camera device is switched to the non-imaging state.
