Description

Technical Field

[0001] This disclosure relates to camera modules. Background Technology

[0002] Camera modules can be installed in smartphones, laptops, vehicles, or other devices. For a camera module to operate effectively, external light needs to enter the module without interference. However, during use, foreign objects may adhere to the area where light enters the camera module, and these foreign objects may interfere with the light entering the module.

[0003] Therefore, a camera module capable of removing foreign objects attached to the area where light is incident is desired. Summary of the Invention

[0004] The summary portion of this invention is intended to provide a brief overview of the chosen concepts, which will be further described in the detailed description portion below. This summary portion is not intended to identify key or essential features of the claimed subject matter, nor is it intended to help determine the scope of the claimed subject matter.

For purposes of clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative dimensions, scale, and depiction of elements in the drawings may be exaggerated. Detailed Implementation

[0029] The following detailed embodiments are provided to help readers gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, except for operations that must occur in a specific order, as will become apparent upon understanding the disclosure of this application. Furthermore, for clarity and conciseness, descriptions of functions and structures well-known to those skilled in the art may be omitted.

[0030] The features described herein may be implemented in various forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will become apparent upon understanding the disclosure of this application.

[0031] The use of the word "may" relative to examples or implementations (e.g., regarding what an example or implementation may include or implement) means that there exists at least one example or implementation that includes or implements such features, but not all examples and implementations are necessarily limited to this.

[0032] Throughout this specification, when an element such as a layer, region, or substrate is described as being "on," "connected to," or "attached to" another element, the element may be directly "on," directly "connected to," or directly "attached to" the other element, or there may be one or more other elements between the element and the other element, or these elements may be physically connected and electrically connected, or these elements may be integral, although they may be referred to by different names depending on their location or function. Conversely, when an element is described as being "directly on," "directly connected to," or "directly attached to" another element, there are no other elements between the element and the other element.

[0033] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items.

[0034] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited by these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, first part, first region, first layer, or first section mentioned in these examples may also be referred to as a second component, second part, second region, second layer, or second section.

[0035] Spatial relative terms such as “above,” “above,” “below,” and “under” may be used herein for descriptive convenience to describe the relationship of one element relative to another, as illustrated in the accompanying drawings. In addition to covering the orientation depicted in the drawings, these spatial relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “above” another element would be located “below” or “under” that other element. Thus, depending on the spatial orientation of the device, the term “above” covers both orientations of “above” and “below”. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0036] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the terms “a,” “an,” and “the” are intended to include the plural form as well. The terms “comprising,” “including,” and “having” indicate the presence of the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0037] Furthermore, throughout this specification, "plan view" refers to the object component viewed from above, and "section view" refers to the vertically cut section of the object component viewed from the side.

[0038] Figure 1 A camera module 1 according to an embodiment is shown. Figure 2 yes Figure 1 Longitudinal cross-sectional view of the light incident component 30 and the wiper 40, and Figure 3 yes Figure 1 A longitudinal cross-sectional view of the central region of camera module 1 in the vertical direction.

[0039] Reference Figures 1 to 3According to the embodiment, the camera module 1 may include a lens barrel 10, a carrier 20, a light incident member 30, a wiper 40, a support member 50, a drive module 60, and a housing 70.

[0040] The lens barrel 10 can accommodate at least one lens. The lens barrel 10 may have a cylindrical hollow space to accommodate at least one lens for imaging an object. When multiple lenses are provided, the multiple lenses can be mounted to the lens barrel 10 along the optical axis OA. The optical axis OA can be oriented in the vertical direction. The multiple lenses are arranged in the required number according to the design of the lens barrel 10, and each lens can have optical properties such as the same or different refractive indices.

[0041] The lens barrel 10 can transmit downward light incident from above. The direction from the upper to the lower part of the lens barrel 10 is the direction in which light enters from the outside towards the lens barrel 10, and can be the direction in which an external object is located, as captured by the camera module 1. The lower part of the lens barrel 10 can be positioned within the camera module 1 in the direction in which the light passing through the lens barrel 10 forms an image. Figure 3 The image shows the upper part of the lens barrel 10 pointing towards the upper part of the image, and the lower part of the lens barrel 10 pointing towards the lower part of the image. Therefore, the upper part of the lens barrel 10 can be the upper part of the camera module 1, and the lower part of the lens barrel 10 can be the lower part of the camera module 1.

[0042] The carrier 20 can accommodate the lens barrel 10. The carrier 20 can accommodate the lens barrel 10 through a structure that contacts at least a portion of the outer surface of the lens barrel 10. For example, a hole corresponding to the outer surface of the lens barrel 10 is formed in the central region of the interior of the carrier 20, so that the lens barrel 10 can be inserted into the carrier 20.

[0043] The light incident member 30 may be at least partially disposed above the upper end of the lens barrel 10. The light incident member 30 is exposed to the outside. The light incident member 30 is provided with a light-transmitting material and may be disposed on the optical axis OA. For example, the light incident member 30 may be transparent. Therefore, external light can enter the lens barrel 10 via the light incident member 30. For example, the light incident member 30 may be the uppermost lens among at least one lens. Furthermore, the light incident member 30 may be disposed separately from the lens and may be a lens cap disposed above the uppermost lens. The light incident member 30 may be fixed to the lens barrel 10. The light incident member 30 may have an upwardly convex dome structure.

[0044] The wiper 40 can be positioned in the area where light is incident towards the lens barrel 10. The wiper 40 can be positioned above the lens barrel 10. The wiper 40 can be positioned above the light incident member 30. The wiper 40 can remove foreign matter from the outer surface 31 of the light incident member 30 while moving relative to the light incident member 30.

[0045] The inner side 41 of the wiper 40 facing the lens barrel 10 and the light incident member 30 can be curved to correspond to the outer surface 31 of the light incident member 30. In addition, the inner side 41 of the wiper 40 may not contact the outer surface 31 of the light incident member 30.

[0046] The inner side 41 of the wiper 40 may have protrusions and recesses. For example, at least one or more holes 400 are formed in the wiper 40, such that the inner side 41 of the wiper 40 may have protrusions and recesses. Therefore, the inner side 41 of the wiper 40 exhibits a capillary effect through the protrusions and recesses, thereby effectively removing foreign matter from the outer surface 31 of the light incident member 30.

[0047] Furthermore, the inner side 41 of the wiper 40 can be made of a hydrophilic material. For example, the inner side 41 of the wiper 40 can be made hydrophilic by plasma treatment. Alternatively, the inner side 41 of the wiper 40 can be made of a hydrophilic polymer (such as polyvinyl alcohol or other hydrophilic polymers), or can be coated with a hydrophilic polymer. When the inner side 41 of the wiper 40 is hydrophilic, foreign matter on the outer surface 31 of the light incident member 30 can be effectively removed.

[0048] Furthermore, the voltage application line 45 can be connected to the wiper 40. The voltage application line 45 can be connected to a power supply 46 for cleaning. The wiper 40 can be energized by the voltage applied by the cleaning power supply 46. When the wiper 40 is energized, foreign matter on the outer surface 31 of the light incident member 30 can be removed more effectively by the attraction generated by the electric charge.

[0049] The support member 50 can support the wiper 40. One end of the support member 50 in the longitudinal direction can be rotatably connected to the pivot pin 200. The pivot pin 200 can be connected to the carrier 20. The length direction of the pivot pin 200 can extend in the horizontal direction. The other end of the support member 50 in the longitudinal direction can be connected to the wiper 40.

[0050] The support member 50 may include a first support member 51 and a second support member 52. The first support member 51 and the second support member 52 may be disposed on opposite sides of the lens barrel 10. The other end of the first support member 51 in the longitudinal direction and the other end of the second support member 52 in the longitudinal direction may be respectively connected to the opposite ends of the wiper 40 in the longitudinal direction of the wiper 40.

[0051] Figure 4 This shows the view towards the lens barrel 10. Figure 3 The drive module 60 and the first support member 51, Figure 5 The outer surface of the carrier 20 in the region where the drive module 60 is located, as viewed towards the lens barrel 10, is shown. Figure 6 It shows the relationship with Figure 5 The outer surface of the carrier 20 shown faces the inner surface of the drive member 600.

[0052] Reference Figures 3 to 6 The drive module 60 can provide power to the wiper 40 to move relative to the light incident member 30. The wiper 40 can be driven in a sweeping motion by the power provided by the drive module 60. The drive module 60 can provide power to rotate the first support member 51 about the pivot pin 200. The drive module 60 may include a drive member 600, a coil 610, and a yoke 620. The drive member 600 may be positioned facing the first support member 51.

[0053] The driving member 600 may be configured such that at least some regions are magnetic, and thus it can move according to a magnetic force applied from the outside. The driving member 600 includes an N-pole region 601a and an S-pole region 601b, and the N-pole region 601a and S-pole region 601b may be arranged in a direction intersecting the vertical direction. For example, the N-pole region 601a and S-pole region 601b may be arranged in a horizontal direction. A portion of the driving member 600 is inserted into the first support member 51 for slidable movement.

[0054] The inner surface of the drive member 600 may face the outer surface of the carrier 20. The outer surface of the drive member 600 may be away from the lens barrel 10 and the carrier 20. The ball bearing member 640 may be disposed between the drive member 600 and the carrier 20.

[0055] The drive component 600 may include a magnetic component 601, a guide pin 602, and a support component 603.

[0056] The magnetic component 601 may be magnetic. The magnetic component 601 may include an N pole region 601a and an S pole region 601b.

[0057] The guide pin 602 can be configured to protrude outward from the outer surface of the drive member 600 by a predetermined length. For example, the inner end of the guide pin 602 facing the lens barrel 10 and the carrier 20 can be inserted into and fixed to the magnetic member 601. The inner end of the guide pin 602 can be connected to the magnetic member 601 in the region where the N pole region 601a and the S pole region 601b meet. A sliding hole 510 can be formed in the first support member 51. The sliding hole 510 can have a slit shape with a predetermined length in the longitudinal direction of the first support member 51. The guide pin 602 can be inserted into the sliding hole 510. During the operation of the drive module 60, the guide pin 602 can slide within the sliding hole 510.

[0058] The support member 603 may be disposed in at least some regions of the outer periphery of the magnetic member 601. For example, the support member 603 may be disposed above the top and below the bottom of the magnetic member 601. Furthermore, the support member 603 may be configured to surround the outer periphery of the magnetic member 601. That is, the support member 603 is configured as a ring structure corresponding to the outer periphery of the magnetic member 601, and thus the magnetic member 601 can be inserted into the inner side of the support member 603.

[0059] At least one of the inner guide grooves 606 and 607 may be formed in the inner surface of the drive member 600. The length direction of the inner guide grooves 606 and 607 may extend in the horizontal direction.

[0060] The inner guide grooves 606 and 607 may include a first inner guide groove 606 and a second inner guide groove 607.

[0061] A first inner guide groove 606 may be formed in the inner upper surface of the drive member 600. The first inner guide groove 606 may also be formed in the region on the inner surface of the support member 603 above the magnetic member 601. The first inner guide groove 606 may be formed across the region above the N-pole region 601a and the S-pole region 601b. In this case, the first inner guide groove 606 may have portions that are connected to each other above the N-pole region 601a and the S-pole region 601b. Alternatively, the first inner guide groove 606 may have portions that are disconnected from each other above the N-pole region 601a and the S-pole region 601b. Figure 6 An example is shown where the portion of the first inner guide groove 606 located above the N pole region 601a and the portion located above the S pole region 601b are disconnected from each other.

[0062] The second inner guide groove 607 can be formed in the inner lower surface of the drive member 600. The second inner guide groove 607 can also be formed in the region on the inner surface of the support member 603 located below the magnetic member 601. The second inner guide groove 607 can be formed to span the regions located below the N-pole region 601a and below the S-pole region 601b. In this case, the second inner guide groove 607 can have portions that are connected to each other located below the N-pole region 601a and below the S-pole region 601b. Alternatively, the second inner guide groove 607 can have portions that are disconnected from each other located below the N-pole region 601a and below the S-pole region 601b. Figure 6 An example is shown where the portion of the second inner guide groove 607 located below the N pole region 601a and the portion located below the S pole region 601b are disconnected from each other.

[0063] The coil 610 generates a magnetic field around itself by applying electrical energy, and the interaction between the magnetic field and the drive member 600 causes the drive member 600 to move. The coil 610 is spaced apart from the outer surface of the drive member 600, and therefore can be positioned to face the outer surface of the drive member 600. That is, the drive member 600 can be positioned between the carrier 20 and the coil 610. The coil 610 is arranged in a ring shape, and therefore the guide pin 602 can be positioned to be inserted into the internal space of the coil 610. The coil 610 can be fixed in place relative to the lens barrel 10 and the carrier 20 by means of a coil fixing member 615. For example, the coil 610 can be connected to the carrier 20 by means of the coil fixing member 615.

[0064] The yoke 620 is configured to face at least a portion of the inner surface of the drive member 600. The yoke 620 may also be configured to face the inner surface of the magnetic member 601. The position of the yoke 620 may be fixed. The yoke 620 may be connected to the carrier 20. For example, at least a portion of the yoke 620 may be fixed to the carrier 20 by inserting the yoke 620 into the carrier 20. The yoke 620 is made of a material that generates a magnetic attraction with the drive member 600, and thus a magnetic attraction is generated between the yoke 620 and the drive member 600. For example, the yoke 620 may be made of a metallic material that is a magnetic material.

[0065] The outer surface of the carrier 20 and the inner surface of the drive member 600 may be spaced apart from each other. Furthermore, the outer surface of the yoke 620 and the inner surface of the drive member 600 may be spaced apart from each other. At least one of the outer guide grooves 201 and 202 may be formed in the outer surface of the carrier 20. The length direction of the outer guide grooves 201 and 202 may extend in the horizontal direction.

[0066] The outer guide grooves 201 and 202 may include a first outer guide groove 201 and a second outer guide groove 202.

[0067] The first outer guide groove 201 can be disposed above the yoke 620. The first outer guide groove 201 can be positioned at a height corresponding to the height of the first inner guide groove 606. The distance between opposite ends of the first outer guide groove 201 in the horizontal direction can be equal to the distance between opposite ends of the first inner guide groove 606 in the horizontal direction. The areas of the first outer guide groove 201 disposed on opposite sides in the horizontal direction can be connected to each other. Alternatively, the areas of the first outer guide groove 201 disposed on opposite sides in the horizontal direction can be disconnected from each other. Figure 5 The image shows a first outer guide groove 201 positioned horizontally on opposite sides, with the regions disconnected from each other.

[0068] The second outer guide groove 202 can be disposed below the yoke 620. The second outer guide groove 202 can be positioned at a height corresponding to the height of the second inner guide groove 607. The distance between the opposite ends of the second outer guide groove 202 in the horizontal direction can be equal to the distance between the opposite ends of the second inner guide groove 607 in the horizontal direction. The areas of the second outer guide groove 202 disposed on opposite sides in the horizontal direction can be connected to each other. Alternatively, the areas of the second outer guide groove 202 disposed on opposite sides in the horizontal direction can be disconnected from each other. Figure 5 The image shows the second outer guide groove 202 being positioned horizontally on opposite sides, with the regions disconnected from each other.

[0069] Ball support members 640 may be disposed between inner guide grooves 606 and 607 and outer guide grooves 201 and 202. Some of the ball support members 640 may be disposed between the first inner guide groove 606 and the first outer guide groove 201. These ball support members 640 may be disposed in the regions of the first inner guide groove 606 on opposite sides in the horizontal direction and the first outer guide groove 201 on opposite sides in the horizontal direction.

[0070] Furthermore, some of the ball bearings 640 may be disposed between the second inner guide groove 607 and the second outer guide groove 202. These ball bearings 640 may be disposed in the regions on opposite sides of the second inner guide groove 607 in the horizontal direction and on opposite sides of the second outer guide groove 202 in the horizontal direction.

[0071] For better understanding and ease of description, Figure 5 The ball support 640 disposed in the outer guide grooves 201 and 202 is shown, and Figure 6 These same ball bearings 640 are shown, which are disposed in the inner guide slots 606 and 607.

[0072] The attraction between the yoke 620 and the drive member 600 prevents the drive member 600 from detaching from the yoke 620. Furthermore, the outer surface of the yoke 620 and the inner surface of the drive member 600 are prevented from sticking together by the ball bearing 640. Therefore, the drive member 600 can move effectively by the magnetic force generated by the coil 610. Moreover, the drive member 600 can move effectively in the horizontal direction relative to the carrier 20 and the coil 610 by means of the inner guide grooves 606 and 607, the outer guide grooves 201 and 202, and the ball bearing 640.

[0073] The housing 70 surrounds the lens barrel 10, the carrier 20, and the drive module 60. Furthermore, the support member 50 may be disposed inside the housing 70.

[0074] Figure 7 and Figure 8 The operating status of the drive module 60 is shown.

[0075] Reference Figure 7 and Figure 8 Power can be applied to the coil 610 of the drive module 60. The power applied to the coil 610 can be supplied from a vehicle, electronic device, or other device in which the camera module 1 is mounted. The power applied to the coil 610 is in alternating current (AC), and therefore AC current can flow through the coil 610. Consequently, the magnetic field generated around the coil 610 varies in magnitude and direction. Therefore, when a magnetic field is formed around the coil 610 in one direction, such as... Figure 7 As shown, the drive member 600 can move to the left relative to the coil 610 due to the force acting between the magnetic field and the magnetic member 601 of the drive member 600. During this process, the first support member 51 can rotate to the left due to the leftward movement of the guide pin 602.

[0076] Furthermore, when the direction of the magnetic field formed around coil 610 is... Figure 7 In the opposite case shown, the driving member 600 can move to the right relative to the coil 610 due to the force acting between the magnetic field and the magnetic member 601 of the driving member 600, as shown in the diagram. Figure 8 As shown in the diagram. During this process, the first support member 51 can rotate to the right as the guide pin 602 moves to the right.

[0077] Figure 9 This is a cross-sectional view of the wiper 40a of the camera module 1a according to another embodiment.

[0078] Reference Figure 9A cleaning fluid path 400a can be formed inside the wiper 40a. Multiple fluid discharge holes 401a can be formed in the inner surface 41a of the wiper 40a. The fluid discharge holes 401a can communicate with the cleaning fluid path 400a. The cleaning fluid path 400a can be connected to a cleaning fluid supply member 48 via a connecting line 47. The cleaning fluid supply member 48 can supply cleaning fluid. The cleaning fluid supply member 48 can be disposed in a vehicle, electronic device, or other device in which the camera module 1a is mounted. The cleaning fluid can be a cleaning gas such as air, or a cleaning liquid. Cleaning is performed by spraying the cleaning fluid from the wiper 40a towards the outer surface 31 of the light incident member 30.

[0079] Furthermore, the wiper 40a can be made of a transparent material. For example, the wiper 40a can be made of a transparent polymer or other transparent materials. Therefore, even when the wiper 40a is disposed outside the outer surface 31 of the light incident member 30, light can be effectively incident on the light incident member 30.

[0080] According to at least one embodiment of the present disclosure, a camera module capable of effectively removing foreign objects attached to the area where light is incident can be provided.

The examples described herein are to be understood in a descriptive sense only and not for limiting purposes. Descriptions of features or aspects in each example should be considered applicable to similar features or aspects in other examples. Suitable results may still be achieved if the described techniques are performed in a different order, and / or if components in the described system, architecture, device, or circuit are combined in different ways and / or replaced or supplemented by other components or their equivalents. Therefore, the scope of this disclosure is not limited by the specific embodiments but by the claims and their equivalents, and all variations within the scope of the claims and their equivalents should be understood to be included in this disclosure.
