Description

Technical Field

[0001] The present invention relates to the field of camera technology, and in particular to a zoom structure and a camera device. Background Art

[0002] Cameras generally include a zoom lens group and a focus lens group. Optical zoom refers to the process of changing the optical zoom ratio by moving the lens positions in the zoom lens group. The greater the optical zoom ratio, the farther the scene can be photographed. Focusing refers to the process of changing the position of the focus lens group to compensate for the change in the zoom lens ratio so that the image of the scene being photographed is clear.

[0003] In the prior art, two driving devices are usually used to drive the zoom lens group and the focus lens group respectively. However, this method requires a larger travel of the focus lens group, resulting in more power loss and more time spent on driving. Summary of the invention

[0004] In order to solve the above-mentioned problems, the present invention provides a zoom structure and a camera device which can reduce power loss during driving and save time consumed during driving.

[0005] In a first aspect, the present application provides a zoom structure, comprising a first lens structure, a second lens structure, a movable guide plate and a first driving device, wherein the first lens structure and the second lens structure are arranged in an array along a first direction, the movable guide plate comprises a plate body and a first guide portion and a second guide portion spaced apart on the plate body, at least a portion of the first guide portion and at least a portion of the second guide portion are both inclined relative to the first direction, the first lens structure is slidably connected to the first guide portion, and the second lens structure is slidably connected to the second guide portion, and the first driving device is used to drive the first lens structure to move along the first direction, thereby driving the movable guide plate to move along the second direction, and the second lens structure to move along the second guide portion in the first direction, and the first direction is different from the second direction.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Please refer to Figure 1 and Figure 2 , Figure 1 is a cross-sectional schematic diagram of an imaging device provided by a first embodiment of the present invention; Figure 2 yes Figure 1 The figure is a three-dimensional schematic diagram of a partial structure of the zoom structure of the camera device shown.

[0033] The present application provides a camera device 200, which includes an image sensor 201, a circuit board (not shown) and a zoom structure 100. The image sensor 201 is electrically connected to the circuit board. The zoom structure 100 is used to capture light from a subject. The image sensor 201 is used to receive light passing through the zoom structure 100 and convert the received light into an electrical signal.

[0034] The camera device 200 provided in the present application may include but is not limited to a mobile phone with a zoom structure 100 (such as an Android phone, an iOS phone, etc.), a tablet computer, a mobile Internet device (Mobile Internet Devices, MID), a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, etc., and the present application does not limit this.

[0035] The zoom structure 100 comprises a first lens structure 10, a second lens structure 30, a movable guide plate 50 and a first driving device 70. The first lens structure 10 and the second lens structure 30 are arranged in a first direction. The movable guide plate 50 comprises a plate body 51 and a first guide portion 53 and a second guide portion 54 which are arranged on the plate body 51 at intervals. At least a portion of the first guide portion 53 and at least a portion of the second guide portion 54 are inclined relative to the first direction. The first lens structure 10 is slidably connected to the first guide portion 53, and the second lens structure 30 is slidably connected to the second guide portion 54. The first driving device 70 is used to drive the first lens structure 10 to move along the first direction, thereby driving the movable guide plate 50 to move along the second direction, and the second lens structure 30 to move along the second guide portion 54 in the first direction. The first direction is different from the second direction.

[0036] The zoom structure 100 and the camera device 200 provided by the present application can drive the movable guide plate 50 to move along the second direction and drive the second lens structure 30 to move along the second guide portion 54 in the first direction when the first driving device 70 drives the first lens structure 10 to move along the first direction. For example, in this embodiment, Figure 3 As shown, the first slider 13 moves from point A to point B along the first guide portion 53 in the first direction, driving the movable guide plate 50 to move from position I to position II along the second direction (as shown in FIG. Figure 3The area indicated by the dotted line of the lens 201 is driven by the second driving device 70 to move from point C to point D along the second guide portion 54 in the first direction. The process in which the first driving device 70 drives the first lens structure 10 to move along the first direction is the zoom process, and the process in which the moving guide plate 50 moves along the second direction and drives the second lens structure 30 to move along the first direction is the first focusing process. In this way, as the first lens structure 10 moves (i.e., the zoom process), the second lens structure 30 can also move accordingly to adjust the position (i.e., the first focusing process), so that the light of the object passing through the first lens structure 10 can form a clear image on the image sensor 201, saving the travel requirement of the second lens structure 30, that is, there is no need to move the second lens structure 30 for a long travel alone, which can reduce the dynamic tilt (Tilt) of the second lens structure 30 in the moving travel, reduce the power loss during driving, and save the time consumed during driving.

[0037] In this embodiment, the second direction is perpendicular to the first direction. It can be understood 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 can also be an acute angle or an obtuse angle.

[0038] When the first lens structure 10 moves along the first direction, it can drive the movable guide plate 50 to move along the second direction. It can be understood that the first lens structure 10 moves relative to the movable guide plate 50, and the moving path of the first lens structure 10 relative to the movable guide plate 50 is the same as at least a part of the extension path of the first guide portion 53. Similarly, when the movable guide plate 50 moves along the second direction and drives the second lens structure 30 to move along the first direction, it can be understood that the second lens structure 30 moves relative to the movable guide plate 50, and the moving path of the second lens structure 30 relative to the movable guide plate 50 is the same as at least a part of the extension path of the second guide portion 54.

[0039] See also Figure 4, during the movement of the first lens structure 10 relative to the movable guide plate 50, the position of the first lens structure 10 in the first guide portion 53 and the position of the second lens structure 30 in the second guide portion 54 always correspond one to one. For example, during the movement of the first lens structure 10 relative to the movable guide plate 50 from the G1 position to the N1 position, the second lens structure 30 also moves relative to the movable guide plate 50 from the G2 position to the N2 position. When the first lens structure 10 is located at the G1 position in the first guide portion 53, the second lens structure 30 is located at the G2 position of the second guide portion 54, and the line connecting the G1 position and the G2 position is parallel to the first direction. When the first lens structure 10 is located at the N1 position of the first guide portion 53, the second lens structure 30 is located at the N2 position of the second guide portion 54, and the line connecting the N1 position and the N2 position is parallel to the first direction. Among them, the moving distance of the first lens structure 10 in the first direction is the length of the line connecting the G1 position and the N1 position in the first direction. When the second lens structure 30 moves 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 line between the G2 position and the N2 position in the first direction. In this embodiment, the length of the line between the G1 position and the N1 position in the first direction is less than the length of the line between the G2 position and the N2 position in the first direction.

[0040] In the present embodiment, the first guide portion 53 extends in a straight line, and the second guide portion 54 extends in a straight line. 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 extension path of the first guide portion 53, and the second end 533 is located on the side of the first end 531 close to the positive direction of the second direction. The second guide 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 extension path of the second guide portion 54, and the fourth end 543 is located on the 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 arranged 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 arranged on the side of the third end 541 facing the positive direction of the first direction. The extension path length of the first guide portion 53 is smaller than the extension path length of the second guide portion 54, and the length of the first guide 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 the length of the second guide 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 along the first direction toward the side close to the image sensor 201 (i.e., the negative direction of the first direction), the second lens structure 30 also moves along the first direction toward the side close to the image sensor 201 (i.e., the negative direction of the first direction); or, when the first lens structure 10 moves along the first direction toward the positive direction of the first direction, the second lens structure 30 also moves along the first direction toward the positive direction of the first direction; and the distance moved by the second lens structure 30 along the first direction is greater than the distance moved by the first lens structure 10 along the first direction.

[0041] The extension path of the first guide portion 53 and the extension path of the second guide portion 54 need to be set corresponding to the positional 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 extension path of the first guide portion 53 needs to satisfy the path of the first lens structure 10 moving relative to the movable guide plate 50, and the extension path of the second guide portion 54 needs to satisfy the path of the second lens structure 30 moving relative to the movable guide plate 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.

[0042] It can be understood that the first guide portion 53 is not limited to extending along a straight line and the second guide portion 54 is not limited to extending 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 curve. In a modified embodiment, the first guide portion 53 extends along a curve and the second guide portion 54 extends along a curve. In a modified embodiment, the first guide portion 53 extends along a curve and the second guide portion 54 extends along a straight line.

[0043] It can be understood that the length of the extension path of the first guide portion 53 is not limited to be smaller than the length of the extension path of the second guide portion 54, and the length of the first guide 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 guide 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 a modified embodiment, the length of the extension path of the first guide portion 53 can be greater than the length of the extension path of the second guide portion 54. In a modified embodiment, the length of the first guide portion 53 along the first direction (i.e., the distance between the first end 531 and the second end 533 in the first direction) can be greater than the length of the second guide portion 54 along the first direction (i.e., the distance between the third end 541 and the fourth end 543 in the first direction).

[0044] It can 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 not limited to being disposed on the side of the third end 541 facing the positive direction of the first direction. In a modified embodiment, the second end 533 of the first guide portion 53 may be, but is not limited to, 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 negative direction of the first direction. In this way, 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 along the positive direction of the first direction, the second lens structure 30 also moves along the positive direction of the first direction.

[0045] It can be understood that 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. In the modified embodiment, when the first lens structure 10 moves along the negative direction of the first direction, the second lens structure 30 can move along the positive direction of the first direction; when the first lens structure 10 moves along the positive direction of the first direction, the second lens structure 30 can move along the negative direction of the first direction. Correspondingly, the second end 533 of the first guide portion 53 is arranged 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 arranged on the side of the third end 541 facing the positive direction of the first direction; or, the second end 533 of the first guide portion 53 is arranged 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 arranged on the side of the third end 541 facing the negative direction of the first direction.

[0046] like Figure 1 and Figure 2As shown, the first lens structure 10 includes a first lens group 11, a first slider 13 and a first lens bracket 15 which are fixedly connected. The first slider 13 is slidably connected to a first guide portion 53. Specifically, the first guide portion 53 is a first slot provided on the plate body 51, and the first slider 13 is movably accommodated in the first slot.

[0047] The first lens holder 15 is provided with a first groove 151 extending along the first direction and a second groove 153 extending along the first direction. The second groove 153 is arranged on a side of the first lens holder 15 away from the first groove 151. The first lens group 11 is fixedly accommodated in the first groove 151. The second lens structure 30 is movably accommodated in the second groove 153. In this way, 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 arranged on the same optical axis. When the first lens structure 10 moves along the first direction, the second lens structure 30 can also move a corresponding distance in the second groove 153.

[0048] It can be understood that the first lens holder 15 is not limited to include the second groove 153 , and the second lens structure 30 is movably accommodated in the second groove 153 , that is, the second groove 153 can also be omitted, and the second lens structure 30 only needs to be slidably connected to the first lens holder 15 .

[0049] In this 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 guide portion 54, and the second lens housing 35 is movably accommodated in the second groove 153. The second guide portion 54 is a second narrow groove arranged on the plate body 51, and the second slider 33 is movably accommodated in the second narrow groove. The second lens group 31 is slidably connected to the second lens housing 35 along the first direction through an elastic element (not shown). The elastic element is used to provide support for the second lens group 31 and reserve space for the movement of the second lens group 31 relative to the second lens housing 35. The second lens group 31 is used to make the light of the subject clearly imaged on the image sensor 201. The second lens housing 35 is used to drive the second lens group 31 to move while zooming, thereby completing the first focusing process. Specifically, when the first lens structure 10 moves along the first direction (zooming process), the second lens group 31 can move along the first direction with the second lens housing 35 (first focusing process). The second driving device is used to drive the second lens group 31 to move relative to the second lens housing 35 along the first direction, that is, after the first focusing process is completed, the second driving device can drive the second lens group 31 to move relative to the second lens housing 35 along the first direction, further adjust the distance between the second lens group 31 and the first lens structure 10, that is, adjust the distance from the second lens group 31 to the image sensor 201, complete the second focusing process, and further improve the clarity of the image. Compared with the prior art, before the second focusing process is performed, the present application allows the second lens structure 30 to move a certain distance with the first lens structure 10, thereby reducing the travel requirement of the second lens group 31 disposed inside the second lens structure 30. Subsequently, the second lens group 31 only needs to make a small range of adjustment inside the second lens structure 30 to perform a small travel focusing and focus-finding action, that is, it can achieve a higher clarity, thereby reducing the power loss during driving and saving the time consumed during driving.

[0050] In this embodiment, the first lens group 11 and the second lens group 31 have the same optical axis (eg Figure 1 It is understood that the first lens group 11 and the second lens group 31 are not limited to be arranged on the same optical axis, as long as the light passing through the first lens group 11 can be irradiated onto the image sensor 201 through the second lens group 31.

[0051] In this embodiment, the elastic element may be, but is not limited to, a spring sheet or the like.

[0052] It can be understood that the first guide portion 53 is not limited to being a first narrow groove provided on the plate body 51, and the first slider 13 is movably accommodated in the first narrow groove. All situations that the first slider 13 can slide along the first guide portion 53 are within the protection scope of the present application. For example, in a modified embodiment, the first guide portion 53 can be, but is not limited to, a guide rod, and the first slider 13 is movably sleeved on the guide rod, so that the first slider 13 can move along the first guide portion 53. Similarly, the second guide portion 54 is not limited to being a second narrow groove provided on the plate body 51, and the second slider 33 is movably accommodated in the second narrow groove. All situations that the second slider 33 can slide along the second guide portion 54 are within the protection scope of the present application. For example, in a modified embodiment, the second guide portion 54 can 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 guide portion 54.

[0053] The first driving device 70 is a piezoelectric driving device, that is, it utilizes the inverse piezoelectric effect of piezoelectric ceramic materials. When a certain voltage is input, the piezoelectric driving device will generate a deformation that gradually increases as the voltage increases, thereby converting electrical energy into mechanical motion, and has a series of advantages such as high strength, low power consumption, fast response speed, and high displacement control accuracy. It can be understood that the first driving device 70 is not limited to a piezoelectric driving device. The first driving device 70 can also be, but not limited to, a stepping motor, a DC servo motor, or an AC servo motor, that is, the first driving device 70 can drive the first lens structure 10 to move along the first direction. It can be understood that the type of the second driving device is not limited. The second driving device can be, but not limited to, a stepping motor, a DC servo motor, or an AC servo motor, that is, the second driving device can drive the second lens group 31 to move relative to the second lens housing 35 along the first direction.

[0054] Please refer to Figure 5 , Figure 6 and Figure 7 The zoom structure 100 further includes a housing assembly 80 and a third lens structure 90. The housing assembly 80 includes a cover plate 81 and a peripheral wall 83 that are fixedly connected. The cover plate 81 and the peripheral wall 83 are arranged to form a receiving space 85. The first lens structure 10 and the second lens structure 30 are both movably received in the receiving space 85 along a first direction. The movable guide plate 50 is slidably connected to the cover plate 81 along a second direction. A third groove 831 is provided on the peripheral wall 83. The third groove 831 is located on the side of the first lens structure 10 away from the second lens structure 30. The third lens structure 90 is fixedly received in the third groove 831.

[0055] In this embodiment, the third lens structure 90 includes a third lens (such as Figure 1 91) and a third lens holder 93, the third lens holder 93 is fixedly accommodated in the third groove 831, and is used for the third lens (as shown in FIG. Figure 181) to provide support. Figure 1 As shown, the third lens 81 is disposed on the same optical axis as the first lens group 11 . It can be understood that the third lens 81 is not limited to being disposed on the same optical axis as the first lens group 11 , as long as the light passing through the third lens 81 can irradiate the first lens group 11 .

[0056] The housing assembly 80 further includes a third guide portion 87 and a fourth guide portion 88.
