Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a zoom lens and an electronic device. Background Art

[0002] Multi-group zoom lenses are an important development in the field of optics in recent years. Different from traditional lenses, multi-group zoom lenses contain multiple lens groups, and the zoom and focus of the lens are achieved by the combination of lens groups.

[0003] In the related art, the zoom lens group and the focus lens group in the multi-group zoom lens move independently of each other. The focus of the lens is related to the relative distance between the two groups. If the lens needs to be zoomed after the focus has been completed, the zoom lens group will move, and in order to maintain the previous focus effect, the focus lens group also needs to move with the zoom lens group to keep the relative distance unchanged. This meaningless movement of the focus lens group brings a certain amount of power consumption loss and may affect the focus effect due to the change in relative position. Utility Model Content

[0004] In order to overcome the problems existing in the related art, the present disclosure provides a zoom lens and an electronic device, which can solve the above problems.

[0005] According to a first aspect of an embodiment of the present disclosure, a zoom lens is provided, comprising: a first driving module, a second driving module, and a zoom lens group and a focus lens group arranged in sequence along the direction from the object side to the image side of the optical axis, wherein the lens barrel of the zoom lens group comprises a dragging structure; the focus lens group is arranged on the dragging structure to move together with the zoom lens group along with the dragging structure; the first driving module can drive the zoom lens group to move along the optical axis; and the second driving module can drive the focus lens group to move along the optical axis relative to the zoom lens group.

[0006] In some embodiments, the first driving module includes: a magnet disposed on the base of the zoom lens, and a coil disposed on the lens barrel of the zoom lens group; the second driving module includes: a magnet disposed on the base of the zoom lens, and a coil disposed on the lens barrel of the focus lens group.

[0007] In some embodiments, it further includes: an electrical connection circuit, one end of which is connected to a coil on the barrel of the zoom lens group or the focus lens group, and the other end is connected to a power supply port on the base of the zoom lens.

[0008] In some embodiments, the electrical connection circuit includes a flexible circuit board.

[0009] In some embodiments, the lens barrel of the zoom lens group is recessed inward to form a first accommodating space, and the coil of the first driving module is arranged in the first accommodating space; and / or, the lens barrel of the focus lens group is recessed inward to form a second accommodating space, and the coil of the second driving module is arranged in the second accommodating space.

[0010] In some embodiments, the dragging structure includes: a receiving plate formed by extending the bottom of the lens barrel of the zoom lens group toward the image side.

[0011] In some embodiments, one side of the lens barrel of the zoom lens group extends toward the image side to form a first limiting structure for the focus lens group; the other side of the lens barrel of the focus lens group extends toward the object side to form a second limiting structure for the zoom lens group.

[0012] In some embodiments, it also includes: a fixed lens group, which is arranged on the object side direction of the zoom lens group.

[0013] In some embodiments, it also includes: a prism, which is arranged at the light entrance of the zoom lens and is used to refract the incident light from the incident direction to the optical axis direction of the lens group.

[0014] According to a second aspect of an embodiment of the present disclosure, an electronic device is provided, wherein the electronic device includes the zoom lens as described in the first aspect.

[0015] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0016] The lens barrel of the zoom lens group disclosed in the present invention includes a dragging structure, and the focus lens group is arranged on the dragging structure, so it can move together with the zoom lens group. After the zoom lens completes focusing, if a zoom operation is required, the first driving module can drive the zoom lens group to move along the optical axis direction to achieve zooming. Since the focus lens group is arranged on the dragging structure, the focus lens group will also move together with the zoom lens group under the drive of the first driving module, and the relative position with the zoom lens group does not change, which can reduce the movement stroke of the focus lens group and avoid the problem that the focus lens group still needs to move synchronously under the drive after the zoom lens group moves. After the zoom operation is achieved, if it is necessary to refocus, the focus lens group only needs to be driven by the second driving module to make a small movement relative to the zoom lens group on the dragging structure, which is more conducive to adjusting the focusing effect.

[0017] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a structural schematic diagram of a zoom lens in a related technology according to an embodiment of the present disclosure.

[0029] like Figure 1 As shown, the zoom lens in the related art includes, from the object side to the image side, a prism lens 110, a fixed lens group 120 (first group), a zoom lens group 130 (second group), a focus lens group 140 (third group) and a circuit board 150.

[0030] Figure 2 It is a structural schematic diagram of a zoom lens in a related technology according to an embodiment of the present disclosure. Figure 2 This is a simplified side view of the zoom lens before and after zooming.

[0031] like Figure 2 As shown, the zooming of the zoom lens is achieved by changing the first zoom distance between the fixed lens group 120 and the zoom lens group 130. Since the fixed lens group 120 is set to be fixed on the base of the zoom lens and cannot be moved, in actual operation, the zooming operation is achieved by moving the zoom lens group 130 to change the relative distance between the zoom lens group 130 and the fixed lens group 120, thereby achieving zooming.

[0032] The focus of the zoom lens is achieved by changing the first focus distance between the zoom lens group 130 and the focus lens group 140, wherein the zoom lens group 130 can move, and the focus lens group 140 can also move. If the focus effect is to be kept unchanged, the relative distance between the zoom lens group 130 and the focus lens group 140 needs to be kept unchanged.

[0033] like Figure 2As shown, when the zoom lens performs a zoom operation, the zoom lens group 130 needs to move forward (toward the object side) to change the first zoom distance to the second zoom distance; in this case, if you want to keep the original focus effect unchanged, you need to move the focus lens group 140 forward by the same distance to keep the first focus distance unchanged. In the related art, the zoom lens group 130 and the focus lens group 140 are managed by two independent drive modules, which means that in this zoom operation, both drive modules need to drive the corresponding lens groups forward, resulting in a certain power loss, and if the two drive modules drive the forward movement distances to be different, it will also affect the final zoom and focus effects.

[0034] In order to solve the above technical problems, the present disclosure proposes a zoom lens.

[0035] Figure 3 The present invention is a schematic diagram of a zoom lens structure according to an embodiment of the present invention. The zoom lens can be configured on a terminal. The zoom lens can be used to capture a target image. The terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device and other communication devices.

[0036] like Figure 3 As shown, the zoom lens comprises: a first driving module, a second driving module, and a zoom lens group 330 and a focus lens group 340 arranged in sequence along the direction from the object side to the image side of the optical axis, wherein:

[0037] The lens barrel of the zoom lens group 330 includes a drag structure 331;

[0038] The focus lens group 340 is disposed on the drag structure 331 to move together with the drag structure 331 and the zoom lens group 330;

[0039] The first driving module can drive the zoom lens group 330 to move along the optical axis direction;

[0040] The second driving module can drive the focus lens group 340 to move relative to the zoom lens group 330 along the optical axis direction.

[0041] It should be noted that Figure 3 The structure and connection form of the first driving module and the second driving module are not shown in the figure. Any driving module that can drive the lens group to move along the optical axis direction should be within the protection scope of the present disclosure.

[0042] In some embodiments, the zoom lens includes more than the first driving module, the second driving module, the zoom lens group 330 and the focus lens group 340 .

[0043] The improvement disclosed in the present invention is mainly aimed at the zoom lens group 330 and the focus lens group 340 in the zoom lens, so there are some omissions in other structural components.

[0044] In some embodiments, the lens group includes one or more lenses that are fixed by a lens barrel.

[0045] Mechanical linkage structures or electrical structures such as drive modules can also be arranged on the lens barrel.

[0046] In some embodiments, the focus lens group 340 is disposed on the dragging structure 331 to move together with the dragging structure 331 and the zoom lens group 330 .

[0047] The focus lens group 340 is placed on the drag structure 331. When the first driving module drives the zoom lens group 330 to move along the optical axis, the drag structure will pull the focus lens group 340 forward without sliding; under the drive of the second driving module, the focus lens group 340 can also move along the optical axis on the drag structure 331 to change the relative distance with the zoom lens group 330, thereby changing the focusing effect.

[0048] In some embodiments, the dragging structure 331 may be a receiving plate, a connecting rod with a telescopic structure, or a hook lock.

[0049] Figure 3 It is only a schematic diagram of a possible embodiment and should not constitute a limitation on the scheme of the present disclosure. The present disclosure does not limit the specific form of the towing structure 331.

[0050] In the present disclosure, the focus lens group 340 is arranged on the drag structure 331 of the zoom lens group 330, so that during the zooming process, the focus lens group 340 can move with the zoom lens group 330 without changing the relative position, thereby avoiding the need to drive the two lens groups to move separately through the driving module, reducing power consumption, and after the movement, the relative position of the focus lens group 340 and the zoom lens group 330 does not change, thereby improving reliability. If the focus needs to be adjusted after zooming, the focus lens group 340 can be moved separately through the second driving module, and the focus lens group 340 can be moved to the target position with only a small displacement based on the movement of the zoom lens group 330, rather than driving the focus lens group 340 to move from the original position to the target position through a large amplitude.

[0051] Figure 4 It is a schematic structural diagram of a zoom lens according to an embodiment of the present disclosure.

[0052] like Figure 4As shown, in some embodiments, the first driving module 410 includes: a coil 411 disposed on the base 400 of the zoom lens, and a magnet 412 disposed on the lens barrel of the zoom lens group 330; the second driving module 420 includes: a coil 421 disposed on the base 400 of the zoom lens, and a magnet 422 disposed on the lens barrel of the focus lens group 340.

[0053] The driving module is a combination of a coil and a magnet, and drives the lens module through the magnetic effect of electric current.

[0054] It should be noted that Figure 4 This is just a feasible example. In fact, the coil 411 of the first driving module 410 can be set on one side of the base 400 or on both sides of the base 400; the magnet 412 of the first driving module 410 can be set only on one side of the lens barrel of the zoom lens group 330, or magnets can be set on both sides of the lens barrel. Figure 4 It is a three-dimensional physical illustration, so the viewing angle on the other side is blocked and the arrangement of the coil 421 and the magnet 422 of the second driving module 420 may not be accurately observed. The arrangement of the coil 421 and the magnet 422 of the second driving module 420 may refer to the arrangement on the first driving module 410 side.

[0055] In some embodiments, the magnets 412 of the first driving module 410 are disposed on both sides of the lens barrel of the zoom lens group 330 , and the coils 411 of the first driving module 410 are also disposed on both sides of the base 400 .

[0056] In some embodiments, the magnets 422 of the second driving module 420 are disposed on both sides of the lens barrel of the diagonal lens group 340 , and the coils 421 of the second driving module 420 are also correspondingly disposed on both sides of the base 400 .

[0057] However, compared with the coil, the mass of the magnet is larger. If the magnet is arranged on the lens barrel of the lens group, some power consumption loss will be caused due to the mass of the magnet.

[0058] To solve this technical problem, the present disclosure proposes the following improvement plan.

[0059] Figure 5 It is a schematic structural diagram of a zoom lens according to an embodiment of the present disclosure.

[0060] like Figure 5As shown, in some embodiments, the first driving module includes: a magnet 412 disposed on the base 400 of the zoom lens, and a coil 411 disposed on the barrel of the zoom lens group 330; the second driving module includes: a magnet 422 disposed on the base of the zoom lens, and a coil 421 disposed on the barrel of the focus lens group 340.

[0061] It should be noted that in Figure 5 The base 400 of the zoom lens is omitted. Figure 5 The arrangement of the magnet 422 and the coil 421 of the second driving module on the other side may refer to the arrangement of the magnet 412 and the coil 411 on the first driving module side.

[0062] By setting the heavier magnet 412 on the base and the lighter coil 411 on the lens barrel of the lens group, the size of the lens group can be miniaturized, the mass of the lens group can be reduced, and the weight of the lens group can be reduced, thereby reducing the power consumption required by the driving module to drive the lens group and improving the overall battery life of the zoom lens.

[0063] However, after the coil is set on the lens barrel of the lens group, how to power the coil becomes a new technical problem.

[0064] Figure 6 A schematic structural diagram of a zoom lens is shown according to an embodiment of the present disclosure.

[0065] Figure 6 This is a top view of the zoom lens.

[0066] like Figure 5 and Figure 6 As shown, in some embodiments, the zoom lens further includes: an electrical connection line 510, one end of which is connected to a coil on the lens barrel of the zoom lens group 330 or the focus lens group 340, and the other end is connected to a power supply port on the base 400 of the zoom lens.

[0067] Based on the electrical connection line 510 , the coil on the lens group can obtain power from the power supply port on the base 400 , thereby supporting the driving module to drive the lens module.

[0068] In some embodiments, the power supply port on the base 400 of the zoom lens is powered by the circuit board 150 .

[0069] The circuit board 150 can provide power.

[0070] In some embodiments, the base 400 of the zoom lens is made of metal.

[0071] The entire base 400 can be conductive. In this case, the other end of the electrical connection line 510 only needs to be connected to the base 400 of the zoom lens.

[0072] In some embodiments, the electrical connection circuit 510 includes a flexible printed circuit (FPC).

[0073] In some embodiments, the electrical connection line 510 may be a bent soft board.

[0074] The bending soft board has a certain elasticity, which can ensure that during the movement of the lens group, one side of the bending soft board always maintains good contact with the power supply port on the base 400. On the other hand, the elasticity of the bending soft board also helps to limit the position of the lens group in the zoom lens, which can play a supporting role.

[0075] like Figure 5 As shown, in some embodiments, the lens barrel of the zoom lens group 330 is recessed inward to form a first accommodating space 520, and the coil 411 of the first driving module is arranged in the first accommodating space 520; and / or, the lens barrel of the focus lens group 340 is recessed inward to form a second accommodating space 530, and the coil 421 of the second driving module is arranged in the second accommodating space 530.

[0076] The lens barrel of the lens group is partially hollowed out inward to form an inwardly recessed accommodation space, which can save space occupied by placing the coil, reduce the width of the lens group, further reduce the mass of the lens group, and reduce the power consumption of the drive module when driving the lens module to move.

[0077] like Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments, the dragging structure 331 includes: a receiving plate 331 formed by extending the bottom of the lens barrel of the zoom lens group 330 toward the image side.

[0078] The focus lens group 340 is placed on the receiving plate 331 and can move along with the zoom lens group 330 .

[0079] like Figure 5 As shown, in some embodiments, one side of the lens barrel of the zoom lens group 330 extends toward the image side to form a first limiting structure 540 for the focus lens group 340; the other side of the lens barrel of the focus lens group 340 extends toward the object side to form a second limiting structure 550 for the zoom lens group 330.

[0080] The first limiting structure 540 and the second limiting structure 550 can be respectively disposed on one side of the zoom lens group 330 and the focus lens group 340. Figure 5 The first limiting structures 540 may be provided on both sides of the focus lens group 340 , and the second limiting structures 550 may be provided on both sides of the zoom lens group 330 .

[0081] by Figure 6 For example, facing the object side, the left side of the zoom lens group 330 is limited by the electrical connection circuit 510, and the right side is limited by the second limiting structure 550 formed by the lens barrel of the focus lens group 340, so that the position of the zoom lens group 330 in the zoom lens does not move horizontally to the left and right, and the same is true for the focus lens group 340.

[0082] In some embodiments, the bottom of the lens barrel of the zoom lens group 330 is grooved, and can be moved in the form of a ball or a slide bar in cooperation with the drive of the first driving module.

[0083] Based on the mechanical movement limiting structure such as ball bearings or sliding rods, the zoom lens group 330 can achieve stable movement, reduce friction resistance, save power consumption of the first driving module, and improve overall endurance.

[0084] Correspondingly, in some embodiments, the bottom of the lens barrel of the focusing lens group 340 is grooved, and can be moved in the form of a ball or a slide bar in cooperation with the drive of the first driving module.

[0085] The technical effect achieved is similar to that of the zoom lens group 330 , and will not be described in detail. It should be noted that the movement of the focus lens group 340 is performed on the drag structure 331 of the zoom lens group 330 .

[0086] like Figure 6 shown.

[0087] In some embodiments, the zoom lens further includes: a fixed lens group 120, which is arranged in the object side direction of the zoom lens group.

[0088] The fixed lens group 120 does not move, and cooperates with the zoom lens group 330 to achieve zooming.

[0089] In some embodiments, the zoom lens further includes: a prism 110, which is disposed at the light entrance of the zoom lens and is used to refract the incident light from the incident direction to the optical axis direction of the lens group.

[0090] The structure and function of the prism 110 may refer to similar structures in the related art, and will not be elaborated in this disclosure.

[0091] In some embodiments, the zoom lens further includes: a circuit board 150.

[0092] The circuit board 150 includes a power supply for supplying power, and also includes an image sensor for receiving light passing through the lens group and forming electrical data to finally form an image.

[0093] The zoom lens proposed in the present disclosure has multiple lens groups and a relatively compact overall structure. Compared with the use of multiple single-lens lenses, it can greatly reduce the occupied mainboard area on the terminal, is beneficial to the mainboard ornaments of the terminal, reduces the thickness of the terminal body, and improves the appearance and holding experience.

[0094] When the zoom lens of the present invention is working, for example, taking portrait photography, the focus lens group 340 needs to be moved by the second driving module to change the relative positions of the focus lens group 340 and the zoom lens group 330, thereby achieving focus and completing the photography work at the distance of the shooting target to provide a good image quality experience; and if it is necessary to further shoot distant scenes or shoot facial details, the zoom lens group 330 can be moved by the first driving module to change the distance between the zoom lens group 330 and the fixed lens group 120, thereby achieving zooming and completing the zoom shooting function of farther or more details.

[0095] During the zooming process, the focus lens group 340 will move together with the zoom lens group 330 on the dragging structure 331, keeping the relative position unchanged, so that a good focusing effect can be maintained; if refocusing is required after zooming, it can also ensure that the focus lens group 340 is fine-tuned based on the movement of the zoom lens group 330, effectively reducing the moving stroke of the focus lens group 340 and reducing the distribution of the corresponding magnets, coils and position sensors, thereby achieving weight reduction, power consumption reduction and reliability improvement.

[0096] Finally, the focus lens group 340 and the zoom lens group 330 can be associated to record the relative positions of the focus lens group 340 and the zoom lens group 330 during calibration, thereby improving the focus accuracy and ensuring the focus effect is correct. Compared with the technical solutions in the related art in which the focus lens group 340 and the zoom lens group 330 move independently, the related art needs to record the absolute positions of the two during calibration. In this case, if the zoom lens group 330 does not actually move to the correct position and the actual position is not accurate and does not reach its corresponding absolute position, even if the focus lens group 340 is in the correct absolute position, the zoom and focus effects will be affected at the same time due to the changes in the zoom distance and the focus distance.

[0097] An embodiment of the present disclosure further provides an electronic device, which includes the zoom lens as described in any one of the above embodiments.

[0098] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the disclosure disclosed herein.
