Description

Technical Field

[0001] This application belongs to the field of camera module technology, and particularly relates to a lens and a camera module. Background Technology

[0002] In camera modules, a drive mechanism is typically included to enable focusing or optical image stabilization, and this mechanism is designed to move the lens. The driving performance of the drive mechanism is matched to the weight of the lens to ensure the reliability and accuracy of lens movement. Generally, the better the lens's performance, the larger and more numerous its components, and the heavier its overall weight. This places higher demands on the driving capability of the drive mechanism.

[0003] To meet the driving performance requirements of increasingly larger and heavier lenses, the size of the driving mechanism is also getting bigger and bigger, which greatly increases the overall size of the camera module, increases the difficulty of installation and use, and seriously affects the applicability of the camera module. Summary of the Invention

[0004] This application provides a lens and a camera module, aiming to at least partially solve the technical problems of large size and limited applicability of camera modules. Therefore,

[0005] One aspect of this application provides a lens, comprising:

[0006] The microscope tube has a first tube end and a second tube end;

[0007] The first lens is disposed inside the first barrel end;

[0008] The second lens includes a light-transmitting portion and an edge portion located around the light-transmitting portion. The edge portion is adjacent to the end face of the second barrel end and is located outside the lens barrel.

[0009] A first coil is disposed on the edge portion or the end face of the second cylinder end, and the first coil is wound with a wire and is provided with an electrical connection terminal.

[0010] In some embodiments, the lens includes a first limiting member disposed on the lens barrel, and in the optical axis direction of the second lens, the distance from the edge of the first limiting member away from the lens barrel to the end of the second barrel is a first distance H1, and the second distance from the light-transmitting part to the end of the second barrel is H2, wherein the first distance H1 is greater than the second distance H2.

[0011] In some embodiments, the first limiting member is provided with a support platform for supporting the edge portion.

[0012] In some embodiments, the first limiting member is a cylindrical member, and the cylindrical wall of the first limiting member is blocked on the outer peripheral side of the second lens.

[0013] In some embodiments, the first coil is connected to the end face of the second cylinder and / or the first limiting member.

[0014] In some embodiments, the lens includes a second limiting member disposed on the edge portion, and in the optical axis direction of the second lens, the distance from the edge of the second limiting member away from the lens barrel to the end of the second barrel is a third distance H3, the distance from the light-transmitting portion to the end of the second barrel is a second distance H2, and the third distance H3 is greater than the second distance H2.

[0015] In some embodiments, the second limiting member is a cylindrical member, and the cylindrical wall of the second limiting member is blocked on the outer periphery of the light-transmitting part.

[0016] In some embodiments, the first coil is connected to at least one of the end face of the second cylinder, the second lens, and the second limiting member.

[0017] In some embodiments, the lens further includes a second coil disposed between the first lens and the second lens, and the second coil is made of wire and is provided with a power connection terminal.

The edge of the second lens is located on one side of the end face of the lens barrel, rather than inside the lens barrel, thereby shortening the lens barrel size and reducing its volume. The first coil is wound with a conductive wire and is located on the end face or edge of the lens barrel, serving as a drive coil for a voice coil motor for image stabilization or focus. This allows the space left by the second lens being external to the lens barrel to increase the size of the first coil to obtain greater thrust and improve driving performance. In other words, it can achieve greater driving force while maintaining the overall size of the camera module, meeting the driving requirements of heavier lenses. This balances the high performance, heavy weight, and matching driving force of the camera module, expanding its applicability and promoting the widespread application of lenses.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:

[0041] The camera module configured in a camera module mainly includes a lens, as well as a focusing drive mechanism for focusing or an image stabilization drive mechanism for optical image stabilization. In some high-performance camera modules, in order to meet performance requirements, the overall size and weight of the lens and drive mechanism are usually large, which makes the overall structure of the camera module very large, thus limiting the applicability of high-performance, large-size camera modules.

[0042] Therefore, this application provides a lens and a camera module, which aims to maintain or even reduce the overall size and weight of the camera module while taking into account shooting performance, so as to expand the applicability of the camera module.

[0043] See Figure 1 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the camera module can be configured as a lens composite mechanism with a lens driving mechanism, and the overall size of the camera module can be reduced while maintaining high shooting performance by designing the lens 1 and its driving mechanism.

[0044] Specifically, the lens 1 may include a lens barrel 11, a first lens 12, a second lens 13, and a first coil 14.

[0045] The lens barrel 11 serves as the main support for the lens 1, and as the mounting base for components such as the first lens 12, the second lens 13, and the first coil 14. The lens barrel 11 is a cylindrical component of a certain length, with a first cylindrical end 111 and a second cylindrical end 112 at its two ends. Incident light enters the lens barrel 11 from one of the first cylindrical end 111 and the second cylindrical end 112, and exits from the other cylindrical end.

[0046] The first lens 12 is disposed at the first barrel end 111 of the lens barrel 11 and can serve as the first lens for incident light entering the lens barrel 11. Generally, the first lens 12 can be assembled entirely or partially within the first barrel end 111. It should be noted that the first lens 12 can be configured as a lens group, that is, referring to multiple lenses that are distinct from the second lens 13.

[0047] The second lens 13 is the last lens through which light passes through the lens 1, and includes a light-transmitting part 131 and an edge part 132. The light inside the lens barrel 11 is emitted from the light-transmitting part 131, and the edge part 132 can be disposed around the light-transmitting part 131 as a fixing part for the second lens 13.

[0048] The edge portion 132 is adjacent to the end face 112a of the second barrel end 112; that is, the edge portion 132 is connected to the end face 112a of the second barrel end 112 and does not need to be covered inside the lens barrel 11. Therefore, compared with the mode of covering the second lens 13 through the lens barrel, the embodiment of this application can shorten the lens barrel 11 to a certain extent and reduce the overall weight of the lens by directly fixing the second lens 13 to the end face 112a of the second barrel end 112. This reduces the performance requirements of the lens drive mechanism to a certain extent, allowing the drive mechanism to be made smaller, or the lens size can be increased to a certain extent, thereby obtaining better optical performance with comparable weight and volume.

[0049] The first coil 14 is a drive coil in a lens drive mechanism based on the voice coil motor principle. When energized, it works with a drive magnet to move the lens. Generally, the first coil 14 can be placed on the edge portion 132 or the second barrel end 112, making full use of the outer area of ​​the second lens 13 and the second barrel end 112.

[0050] Compared to the method of covering the second lens 13 with the lens barrel, in this embodiment, the second lens 13 is placed externally, which is equivalent to shortening the lens barrel 11. The first coil 14 has more space to be placed, which allows for a larger overall length and number of turns of the first coil 13. This expands the threshold range of the force between the energized first coil 14 and the driving magnet, giving the lens driving mechanism higher driving capability and improving the lens driving accuracy and reliability. Accordingly, with a similar overall size of the camera module, the driving mechanism has greater driving capability, which can drive larger, higher-performance lenses to a certain extent. This balances the high performance and small size requirements of the camera module and helps to expand the applicability of the camera module.

[0051] It is worth noting that the first coil 14 should be made of wire and equipped with an electrical connection terminal to facilitate connection with an external power source.

[0052] The lens and camera module provided in this application include a lens barrel and a first lens, a second lens, and a first coil mounted on the lens barrel. The edge of the second lens is located on one side of the end face of the lens barrel, rather than inside the lens barrel, thereby shortening the lens barrel size and reducing its volume. The first coil is wound with a conductive wire and is located on the end face or edge of the lens barrel, serving as a drive coil for a voice coil motor for image stabilization or focus. This allows the space left by the second lens being external to the lens barrel to increase the size of the first coil to obtain greater thrust and improve driving performance. In other words, it can achieve greater driving force while maintaining the overall size of the camera module, meeting the driving requirements of heavier lenses. This balances the high performance, heavy weight, and matching driving force of the camera module, expanding its applicability and promoting the widespread application of lenses.

[0053] In some embodiments, the first coil 14 may be wound with small-diameter enameled wire, such as enameled wire with a diameter of less than 0.01 mm, taking into account the electrical safety of the coil, more turns of winding, and structural strength.

[0054] In some embodiments, the edge portion 132 can be bonded to the end face of the second cylindrical end 112 to fix the second lens 13. Alternatively, the first coil 14 can be directly wound around the circumferential side of the edge portion 132 to fix the first coil 14.

[0055] Meanwhile, the first coil 14 can also block stray light from entering the second lens 13 through the circumferential side of the edge portion 132, which can reduce stray light interference to a certain extent.

[0056] See Figure 1 and Figure 2 In some embodiments, considering that at least a portion of the second lens 13 is located outside the lens barrel 11, the lens barrel 11 has insufficient protective capability for the second lens 13; therefore, a limiting structure may also be provided on the lens barrel 11 to protect the second lens 13 and reduce the risk of being scratched or damaged by external structures.

[0057] Specifically, the lens 1 may further include a first limiting member 15, which may be disposed on the lens barrel 11 and on the optical axis direction O of the second lens 13. The side edge of the first limiting member 15 away from the second barrel end 112 is a first edge 152, the distance from the first edge 152 to the second barrel end 112 is a first distance H1, and the distance from the light-transmitting part 131 to the second barrel end 112 is a second distance H2. The first distance H1 is greater than the second distance H2, so that when the lens is assembled and used, the first limiting member 15 can be pressed against the external environment interface, so that a certain gap is left between the light-transmitting part 131 and the external environment interface, thereby preventing the light-transmitting part 131 from being contacted and scratched.

[0058] It is worth noting that the first limiting member 15 is used to limit the distance between the lens barrel 11 and the external environment interface, such as other components, thereby protecting the second lens 13. Under certain specific working conditions, there is a risk that the sharp points or other structures of other components may extend into the lens barrel area and directly contact and damage the light-transmitting part 131. This can be mitigated by configuring the positioning of the lens 1 in conjunction with other components in the camera module.

[0059] In some embodiments, considering that the second lens 13 is located outside the second cylindrical end 112, in order to improve the fixing strength and stability of the second lens 13, a support 151 can be provided in the first limiting member 15, and the support 151 can be provided on the side of the edge portion 132 away from the second cylindrical end 112, that is, the end face 112a of the first cylindrical end 112 and the support 151 are respectively blocked on both axial sides of the edge portion 132, thereby ensuring the positional stability of the second lens 13 in the axial direction.

[0060] Generally, the second lens 13 is located in the central region of the second barrel end 112, and the first limiting member 15 is located radially outside the edge portion 132, thereby restricting the radial movement of the second lens 13 and maintaining the stability of the radial position of the second lens 13.

[0061] In other words, the first limiting member 15 can restrict the position of the second lens 13 from the axial and radial directions, thereby maintaining the stability of the structure and shooting performance of the lens 1.

[0062] In some embodiments, the first limiting member 15 may be configured as a cylindrical member, and the inner wall of the first limiting member 15 is blocked on the radially outer side of the edge portion 132, thereby limiting the radial displacement of the edge portion 132 as a whole. At the same time, the cylindrical member can limit the radial stray light from being projected onto the light-transmitting portion 131 to a certain extent, thereby obtaining better anti-interference ability and helping to maintain shooting performance.

[0063] It is worth noting that the cylinder of the first limiting member 15 can be configured as a thin-walled cylinder, that is, its wall thickness is less than that of the cylinder wall of the lens barrel 11, thereby providing installation space for the first coil 14. Generally speaking, while maintaining the structural strength of the first limiting member 15, the wall thickness of the first limiting member 15 can be set as small as possible to allow the first coil 14 to have a larger installation space.

[0064] In some embodiments, the support 151 may also be provided with an annular structure, which can cover the edge portion 132 as a whole, thereby also blocking the axial stray light of the second lens 13 from entering the second lens 13 and the lens barrel 11 through the edge portion, and maintaining the stability of the lens's shooting performance.

[0065] In some embodiments, the cylinder of the first limiting member 15 can be configured as two cylinders with different inner diameters, and the support 151 can be configured as the end face of the smaller inner diameter cylinder, thereby simplifying the processing operation of the first limiting member 15 to a certain extent.

[0066] In some embodiments, the first limiting member 15 can be fixed on the end face 112a of the second cylindrical end 112, thereby utilizing the flatness of the end face 112a of the second cylindrical end 112 to ensure the installation posture of the first limiting member 15 and reduce the risk of tilting.

[0067] In some embodiments, the edge portion 132, the first limiting member 15, and the cylinder end face 112a of the second cylinder end 112 can be bonded together with an adhesive material, thereby simplifying the assembly operation and improving the overall fixing strength of the edge portion 132 and the first limiting member 15.

[0068] Generally, adhesive material can be filled between the support 151, the inner wall of the first limiting member 15, the end face 112a of the second cylinder end 112 and the edge portion 15 to achieve multi-face bonding and higher fixing reliability.

[0069] In some embodiments, the first coil 14 may be wound around the circumferential side of the first limiting member 15, thereby making the first coil 14 stably mounted on the first limiting member 15.

[0070] Generally, the first coil 14 can be further solidified onto the second cylinder end 112 or the first limiting member 15 using an adhesive material.

[0071] In some embodiments, the first coil 14 can also be configured as an independent element, sleeved on the second limiting member 15, and can be further fixed to the first limiting member 15 or the second cylindrical end 112 by adhesive material.

[0072] Generally, the inner coil shape of the first coil 14 matches the second limiting member 15, thereby stably fixing the first coil 14. The outer coil shape of the first coil 14 can be approximately the same as the outer peripheral surface shape of the first tube end 112, thereby making full use of the tube end space and not increasing the risk of external scratches.

[0073] In some embodiments, the axial length of the first coil 14 may be equivalent to the length of the cylinder of the first limiting member 15, thereby helping to obtain greater driving force.

[0074] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, in order to reduce the size of the lens while also protecting the second lens element 13, the lens 1 may include a second limiting member 16. The second limiting member 16 is disposed on the edge portion 132 and on the optical axis direction O of the second lens element 13. The side edge of the second limiting member 16 away from the lens barrel 11 is a second edge 161. The distance from the second edge 161 to the second barrel end 112 is a third distance H3, and the third distance H3 is greater than the second distance H2. Thus, when the lens is assembled, the second limiting member 16 can press against the external environment interface, leaving a certain gap between the light-transmitting portion 131 and the external environment interface, thereby preventing the light-transmitting portion 131 from being scratched by contact.

[0075] It is worth noting that the second limiting member 16 is used to limit the distance between the lens barrel 11 and the interface with the external environment, thereby protecting the second lens 13. In certain specific working conditions, there is a risk that the sharp points or other structures of other components may extend into the lens barrel area and directly contact and damage the light-transmitting part 131. This can be mitigated by configuring the positioning of the lens 1 in conjunction with other components in the camera module.

[0076] In some embodiments, the second limiting member 16 may be configured as a cylindrical member, thereby limiting the radial stray light from being projected onto the light-transmitting portion 131 to a certain extent, thereby obtaining better anti-interference ability and helping to maintain stable shooting performance.

[0077] In some embodiments, the thickness of the portion of the barrel that contacts the edge portion 132 of the second limiting member 16 may be equivalent to the width of the edge portion 132, thereby completely covering the axial side of the edge portion 132, thereby blocking axial stray light from entering the second lens 13 and the lens barrel 11 through the edge portion 132, and maintaining the stability of the lens's shooting performance.

[0078] It is worth noting that the wall thickness of the second limiting member 16 does not need to match the width of the edge portion 132. The wall thickness of the area away from the edge portion 132 can be set to be smaller, which helps to reduce the total weight of the lens 1.

[0079] In some embodiments, the first coil 14 may be wound around the second limiting member 16 or the circumferential side of the edge portion 132, thereby making the first coil 14 stably mounted on the second limiting member 16 or the second lens 13.

[0080] Furthermore, adhesive material can be filled between the first coil 14 and the second limiting member 16 or the second lens 13 to enhance the fixation reliability.

[0081] In some embodiments, the axial length of the first coil 14 can be set to be equivalent to the thickness of the edge portion 132 or the cylindrical length of the second limiting member 15. Alternatively, the axial length of the first coil 14 can be set to be equivalent to the overall height of the edge portion 132 and the second limiting member 15, thereby obtaining a greater driving force.

[0082] See Figure 8 In some embodiments, multiple spaced-apart lenses are provided within lens 1. To ensure the spacing between the lenses, spacers 17 can be provided between adjacent lenses. To further reduce the weight of lens 1 and improve the driving capability of the lens drive structure based on the voice coil motor principle, the spacers 17 between adjacent lenses can be replaced with drive coils, thereby achieving structural composite.

[0083] Specifically, the lens 1 further includes a second coil 171, which is disposed inside the lens barrel 11 and positioned between the first lens 12 and the second lens 13, or between any two adjacent lenses inside the lens barrel 11, in order to maintain a stable distance between the lenses.

[0084] Meanwhile, the second coil 17 is provided with a power connection terminal for connecting an external driving power supply, thereby realizing the control of the lens driving mechanism. The second coil 17 should be made of wire and equipped with an electrical connection terminal to facilitate connection with an external power supply.

[0085] The second coil 17 is closely attached to the inner wall of the lens barrel 11 and can be further reinforced and fixed by adhesive material.

[0086] In some embodiments, the second coil 17 may be wound with small-diameter enameled wire, such as enameled wire with a diameter of less than 0.01 mm, taking into account the electrical safety of the coil, more turns of winding, and structural strength.

[0087] In some embodiments, a light-blocking layer may be coated on the surface of the edge portion 132 to enhance the ability to resist stray light.

[0088] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the first coil 14 and the second coil 17 may be respectively provided on the lens barrel 11, thereby having a larger coil structure. When the first coil 14 and the second coil 17 are placed in the magnetic field of the driving magnet of the voice coil motor, the energized first coil 14 and the second coil 17 will obtain a larger adjustable range of driving force.

[0089] See Figure 9 , Figure 10 and Figure 11 In some embodiments, a camera module is also provided, including the lens 1, bracket 2 and driving magnet 3. The lens 1 is movably disposed in the bracket 2, the driving magnet 3 is disposed on the bracket 2, and the driving magnet 3 is disposed opposite to the first coil 14 and / or the second coil 17 so that the lens 1 can be driven to move when the first coil 14 and / or the second coil 17 is energized.

[0090] It is worth noting that the first coil 14 and / or the second coil 17 can cooperate with the driving magnet 3 to enable the lens 1 to move along its axial and radial directions, thereby achieving focusing and optical image stabilization.

[0091] In other words, the driving directions of the first coil 14 and the second coil 17 can be flexibly set, meaning that one of the first coil 14 and the second coil 17 can be used for focusing drive, and the other for image stabilization drive. Alternatively, both the first coil 14 and the second coil 17 can be used for image stabilization drive or focusing drive.
