Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic cross-sectional view of an image capturing apparatus according to a first embodiment of the present disclosure; fig. 2 is a schematic perspective view of a partial structure of the zoom structure of the image pickup apparatus shown in fig. 1.

The present application provides an image capturing apparatus 200, which includes an image sensor 201, a circuit board (not shown), and a zooming structure 100, wherein the image sensor 201 is electrically connected to the circuit board, the zooming structure 100 is configured to capture light from a subject, and the image sensor 201 is configured to receive the light passing through the zooming structure 100 and convert the received light into an electrical signal.

The camera device 200 provided in the present application may include, but is not limited to, a Mobile phone (e.g., an Android Mobile phone, an iOS Mobile phone, etc.) with the zoom structure 100, a tablet computer, a Mobile Internet Device (MID), a Personal Digital Assistant (PDA), a notebook computer, etc., which is not limited in this application.

The zoom structure 100 includes a first lens structure 10, a second lens structure 30, a movable guide 50 and a first driving device 70, wherein the first lens structure 10 and the second lens structure 30 are arranged in a first direction, the movable guide 50 includes a plate 51 and a first guide portion 53 and a second guide portion 54 spaced apart from the plate 51, at least a portion of the first guide portion 53 and at least a portion of the second guide portion 54 are both disposed in an inclined manner with respect to the first direction, the first lens structure 10 is slidably connected to the first guide portion 53, the second lens structure 30 is slidably connected to the second guide portion 54, the first driving device 70 is configured to drive the first lens structure 10 to move in the first direction, so as to drive the movable guide 50 to move in a second direction, and the second lens structure 30 moves in the first direction along the second guide portion 54, the first direction is different from the second direction.

The zoom structure 100 and the image capturing apparatus 200 provided in the present application can drive the movable guide 50 to move in the second direction and drive the second lens structure 30 to move in the first direction along the second guide 54 when the first driving device 70 drives the first lens structure 10 to move in the first direction. For example, in the present embodiment, as shown in fig. 3, the first slider 13 moves from a point a to a point B along the first guide portion 53 in the first direction, and drives the movable guide 50 to move from the position I to the position ii (as shown by the dotted line in fig. 3) along the second direction, and further drives the second slider 33 to move from the point C to the point D along the second guide portion 54 in the first direction. The process of the first driving device 70 driving the first lens structure 10 to move along the first direction is a zooming process, and the process of the movable guide 50 moving along the second direction and driving the second lens structure 30 to move along the first direction is a first focusing process. Thus, when the first lens structure 10 moves (i.e., in the zooming process), the second lens structure 30 can also move correspondingly to adjust the position (i.e., in the first focusing process), so that the image of the object light passing through the first lens structure 10 can be clearly formed on the image sensor 201, the stroke requirement of the second lens structure 30 is saved, i.e., the second lens structure 30 does not need to move alone in a large stroke, the dynamic Tilt (Tilt) in the moving stroke of the second lens structure 30 can be reduced, the power loss in the driving process is reduced, and the time consumed in the driving process is saved.

In this embodiment, the second direction is perpendicular to the first direction. It will be appreciated that the second direction is not limited to being perpendicular to the first direction, for example, the angle between the second direction and the first direction may also be an acute angle or an obtuse angle.

When the first lens structure 10 moves along the first direction, the movable guide 50 can be driven to move along the second direction, it can be understood that the first lens structure 10 moves relative to the movable guide 50, and the moving path of the first lens structure 10 relative to the movable guide 50 is the same as at least a part of the extending path of the first guide 53. Similarly, when the movable guide 50 moves in the second direction to move the second lens structure 30 in the first direction, it can be understood that the second lens structure 30 moves relative to the movable guide 50, and the moving path of the second lens structure 30 relative to the movable guide 50 is the same as the at least partial extending path of the second guide 54.

Referring to fig. 4, in the process of moving the first lens structure 10 relative to the movable guide 50, the positions of the first lens structures 10 in the first guide portions 53 and the positions of the second lens structures 30 in the second guide portions 54 are always in one-to-one correspondence. For example, during the movement of the first lens structure 10 relative to the moving guide 50 from the G1 position to the N1 position, the second lens structure 30 also moves relative to the moving guide 50 from the G2 position to the N2 position. When the first lens structure 10 is located at the position of G1 in the first guide 53, the second lens structure 30 is located at the position of G2 in the second guide 54, and the line connecting the position of G1 and the position of G2 is parallel to the first direction. When the first lens structure 10 is located at the position N1 of the first guide 53, the second lens structure 30 is located at the position N2 of the second guide 54, and a line connecting the position N1 and the position N2 is parallel to the first direction. The moving distance of the first lens structure 10 in the first direction is the length of the connection line between the G1 position and the N1 position in the first direction. In the process of moving the second lens structure 30 from the G2 position to the N2 position, the moving distance of the second lens structure 30 in the first direction is the length of the connection line between the G2 position and the N2 position in the first direction, and in this embodiment, the length of the connection line between the G1 position and the N1 position in the first direction is smaller than the length of the connection line between the G2 position and the N2 position in the first direction.

In the present embodiment, the first guide portion 53 extends linearly, and the second guide portion 54 extends linearly. The first guide portion 53 includes a first end 531 and a second end 533, the first end 531 and the second end 533 are respectively located at two ends of the extending path of the first guide portion 53, and the second end 533 is located at a side of the first end 531 close to the positive direction of the second direction. The second guiding portion 54 includes a third end 541 and a fourth end 543, the third end 541 and the fourth end 543 are respectively located at two ends of the extending path of the second guiding portion 54, and the fourth end 543 is located at a side of the third end 541 close to the positive direction of the second direction. In the present embodiment, the second end 533 of the first guide portion 53 is provided on the side of the first end 531 facing the positive direction of the first direction, and the fourth end 543 of the second guide portion 54 is provided on the side of the third end 541 facing the positive direction of the first direction. The extending path length of the first guiding portion 53 is smaller than that of the second guiding portion 54, and the length of the first guiding portion 53 along the first direction (i.e. the distance between the first end 531 and the second end 533 in the first direction) is smaller than that of the second guiding portion 54 along the first direction (i.e. the distance between the third end 541 and the fourth end 543 in the first direction). In this way, when the first lens structure 10 moves toward the image sensor 201 side (i.e., the negative direction of the first direction) in the first direction, the second lens structure 30 also moves toward the image sensor 201 side (i.e., the negative direction of the first direction) in the first direction; alternatively, when the first lens structure 10 moves in the first direction toward the positive direction of the first direction, the second lens structure 30 also moves in the first direction toward the positive direction of the first direction; and the second lens structure 30 moves a distance in the first direction greater than the distance in which the first lens structure 10 moves in the first direction.

The extending path of the first guiding portion 53 and the extending path of the second guiding portion 54 need to be set corresponding to the position relationship between the first lens structure 10 and the second lens structure 30 during the zooming process and the first focusing process, that is, the extending path of the first guiding portion 53 needs to satisfy the moving path of the first lens structure 10 relative to the moving guide 50, and the extending path of the second guiding portion 54 needs to satisfy the moving path of the second lens structure 30 relative to the moving guide 50, so that when the first slider 13 moves a certain distance along the first direction, the second slider 33 also moves a corresponding distance along the first direction.

It is understood that the first guide portion 53 is not limited to extending along a straight line, and the second guide portion 54 extends along a straight line, for example, in a modified embodiment, the first guide portion 53 extends along a straight line, and the second guide portion 54 extends along a curved line. In the modified embodiment, the first guide portion 53 extends along a curve, and the second guide portion 54 extends along a curve. In the modified embodiment, the first guide portion 53 extends along a curved line, and the second guide portion 54 extends along a straight line.

It can be understood that the length of the extending path of the first guiding portion 53 is not limited to be smaller than the length of the extending path of the second guiding portion 54, and the length of the first guiding portion 53 along the first direction (i.e. the distance between the first end 531 and the second end 533 in the first direction) is not limited to be smaller than the length of the second guiding portion 54 along the first direction (i.e. the distance between the third end 541 and the fourth end 543 in the first direction). For example, in the modified embodiment, the extended path length of the first guide portion 53 may be longer than the extended path length of the second guide portion 54. In a modified embodiment, the length of the first guiding portion 53 along the first direction (i.e. the distance between the first end 531 and the second end 533 in the first direction) may be greater than the length of the second guiding portion 54 along the first direction (i.e. the distance between the third end 541 and the fourth end 543 in the first direction).

It is to be understood that the second end 533 of the first guide portion 53 is not limited to being disposed on the side of the first end 531 facing the positive direction of the first direction, and the fourth end 543 of the second guide portion 54 is disposed on the side of the third end 541 facing the positive direction of the first direction. In the modified embodiment, the second end 533 of the first guide portion 53 may be disposed on the side of the first end 531 facing the negative direction of the first direction, and the fourth end 543 of the second guide portion 54 may be disposed on the side of the third end 541 facing the negative direction of the first direction. Thus, when the first lens structure 10 moves along the negative direction of the first direction, the second lens structure 30 also moves along the negative direction of the first direction; when the first lens structure 10 moves in the positive direction of the first direction, the second lens structure 30 also moves in the positive direction of the first direction.

It is understood that the movement of the first lens structure 10 in the negative direction of the first direction is not limited, and the second lens structure 30 also moves in the negative direction of the first direction. In the modified embodiment, when the first lens arrangement 10 is moved in the negative direction of the first direction, the second lens arrangement 30 may be moved in the positive direction of the first direction; when the first lens structure 10 is moved in the positive direction of the first direction, the second lens structure 30 may be moved in the negative direction of the first direction. Accordingly, the second end 533 of the first guide portion 53 is disposed on the side of the first end 531 facing the negative direction of the first direction, and the fourth end 543 of the second guide portion 54 is disposed on the side of the third end 541 facing the positive direction of the first direction; alternatively, the second end 533 of the first guide portion 53 is disposed on the side of the first end 531 facing the positive direction of the first direction, and the fourth end 543 of the second guide portion 54 is disposed on the side of the third end 541 facing the negative direction of the first direction.

As shown in fig. 1 and fig. 2, the first lens structure 10 includes a first lens group 11, a first slider 13 and a first lens holder 15, which are fixedly connected to each other. The first slider 13 is slidably connected to the first guide portion 53. Specifically, the first guiding portion 53 is a first slot disposed on the plate body 51, and the first sliding block 13 is movably received in the first slot.

The first lens support 15 is provided with a first groove 151 extending along a first direction and a second groove 153 extending along the first direction, the second groove 153 is disposed on a side of the first lens support 15 departing from the first groove 151, and the first lens group 11 is fixedly accommodated in the first groove 151. The second lens structure 30 is movably received in the second groove 153. Thus, the second groove 153 provides a guide for the movement of the second lens structure 30, so that the first lens structure 10 and the second lens structure 30 are always disposed on the same optical axis, and when the first lens structure 10 moves along the first direction, the second lens structure 30 can also move in the second groove 153 by a corresponding distance.

It is understood that the first lens support 15 is not limited to include the second groove 153, and the second lens structure 30 is movably received in the second groove 153, i.e. the second groove 153 may be omitted, and the second lens structure 30 is only required to be slidably connected with the first lens support 15.

In the present embodiment, the second lens structure 30 includes a second lens group 31, a second slider 33, a second lens housing 35, an elastic element (not shown), and a second driving device (not shown). The second slider 33 is fixedly connected to the second lens housing 35, the second slider 33 is slidably connected to the second guiding portion 54, and the second lens housing 35 is movably accommodated in the second groove 153. The second guiding portion 54 is a second slot disposed on the plate body 51, and the second slider 33 is movably received in the second slot. The second lens group 31 is slidably coupled to the second lens housing 35 in the first direction by an elastic member (not shown). The elastic member serves to provide support for the second lens group 31 and to make room for movement of the second lens group 31 relative to the second lens housing 35. The second lens group 31 is used to sharply image light rays of a subject on the image sensor 201. The second lens housing 35 is used to bring the second lens group 31 into motion while zooming is performed, thereby completing the first focusing process. Specifically, at the time of movement of the first lens structure 10 in the first direction (zooming process), the second lens group 31 can move in the first direction with the second lens housing 35 (first focusing process). The second driving device is configured to drive the second lens group 31 to move along the first direction relative to the second lens housing 35, that is, after the first focusing process is completed, the second driving device can drive the second lens group 31 to move along the first direction relative to the second lens housing 35, further adjust a distance between the second lens group 31 and the first lens structure 10, that is, adjust a distance between the second lens group 31 and the image sensor 201, complete the second focusing process, and further improve the imaging definition. Compared with the prior art, before the second focusing process, the second lens structure 30 moves a certain distance along with the first lens structure 10, so that the stroke requirement of the second lens group 31 arranged inside the second lens structure 30 is reduced, and the subsequent second lens group 31 only needs to be adjusted within a small range inside the second lens structure 30 to perform focusing and focus searching actions with a small stroke, so that higher definition can be realized.

In the present embodiment, the first lens group 11 and the second lens group 31 are disposed coaxially (L shown in fig. 1). It is understood that the arrangement of the first lens group 11 and the second lens group 31 on the same optical axis is not limited, and it suffices that the light passing through the first lens group 11 can be irradiated onto the image sensor 201 through the second lens group 31.

Similarly, the second guiding portion 54 is not limited to be the second slot disposed on the plate body 51, and the second slider 33 is movably received in the second slot, so that it is within the protection scope of the present application that the second slider 33 can slide along the second guiding portion 54, for example, in the modified embodiment, the second guiding portion 54 may be but is not limited to a guide rod, and the second slider 33 is movably sleeved on the guide rod, so that the second slider 33 can move along the second guiding portion 54.
