Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera technology, and in particular to a camera module. Background Technology
[0002] With the continuous development of electronic technology, portable mobile terminals such as mobile phones, laptops, and PDAs with camera modules have become the most common communication tools in people's daily lives.
[0003] Traditional camera modules with focusing and shake compensation functions are prone to failure due to fatigue or wear during long-term use, which affects the imaging quality and lifespan of the camera module. Utility Model Content
[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a camera module that exhibits good focusing stability and can significantly extend the lifespan of the camera module.
[0005] The camera module according to an embodiment of the present invention includes a focusing mechanism, which includes a carrier, a lens assembly, a bracket, a driving assembly, and a guiding assembly. The lens assembly is mounted on the carrier, and the bracket is an annular bracket sleeved on the outer periphery of the carrier. The driving assembly includes a coil and a magnet. The coil is disposed on the bracket, and the magnet is disposed on the carrier. When the coil is energized, it drives the magnet, thereby causing the magnet to move the carrier. The guiding assembly includes a guide rail and a guide groove. The guide rail is disposed on the bracket, and the guide groove is disposed on the carrier. The guide rail and the guide groove cooperate with each other to guide the movement direction of the carrier.
[0006] The camera module according to this utility model embodiment, by setting a guiding component in which the guide rail and guide groove cooperate with each other, can provide a relatively stable guiding effect for the movement of the carrier, making the focusing mechanism less susceptible to interference from changes in external temperature and humidity. Whether in high-temperature and hot environments or humid and rainy climates, it can ensure accurate focusing of the lens assembly, guaranteeing clear and stable image quality, and can significantly extend the service life of the camera module, reducing repair or replacement costs due to focusing mechanism failures. It boasts high reliability and good stability.
[0007] In addition, the camera module according to this utility model may also have the following additional technical features:
[0008] In some embodiments of this utility model, the guide rail includes a protrusion protruding from the inner circumferential surface of the bracket, and the guide groove includes a recessed portion on the outer circumferential surface of the carrier, with the protrusion and the recess fitting together. Through the mutual fitting of the protrusion and the recess, the carrier can be stably limited when moving along the optical axis, reducing or even eliminating carrier swaying, thereby providing a more stable guiding effect for the carrier.
[0009] In some embodiments of this utility model, the guide rail further includes a guide shaft disposed between the protrusion and the recess, the guide shaft being fixed to the bracket. This can effectively increase the allowable error during manufacturing of the protrusion and recess, thereby reducing the processing difficulty of the bracket and carrier. Furthermore, it can also effectively reduce the assembly difficulty when assembling the carrier and bracket, thus improving assembly efficiency.
[0010] In some embodiments of this invention, two guide rails and two guide grooves are provided, with the two guide rails corresponding to and cooperating with the two guide grooves respectively, wherein the two guide grooves are located on both sides of the carrier. This arrangement makes the carrier more stable when moving along the optical axis.
[0011] In some embodiments of this utility model, the camera module further includes: a first elastic connector, one end of which is connected to the end face of the bracket, and the other end is connected to the end face of the carrier via a first fixing piece. Two first elastic connectors are provided, and the two first fixing pieces and the two guide rails are arranged alternately along the circumference of the carrier. Therefore, when the driving assembly drives the carrier to move along the optical axis, the cooperation of the convex and concave portions, along with the first elastic connector, enables the carrier to move relatively stably and better balances the circumferential forces acting on the carrier. This makes the carrier less prone to shaking when moving along the optical axis, thereby improving the imaging quality of the camera module.
[0012] In some embodiments of this utility model, the bracket has a first end face and a second end face facing away from each other. One end of the first elastic connector is connected to the first end face. The camera module further includes a stabilization mechanism, which includes: a base disposed on the second end face of the bracket; and a second elastic connector connected between the base and the bracket to allow the bracket to move radially relative to the base. At least a portion of the second elastic connector is made of shape memory metal, allowing it to deform when energized. Thus, by utilizing shape memory metal to drive the carrier movement in response to shake compensation requirements, complex coil and magnet structures are eliminated, simplifying the camera module structure and reducing its size and weight, thus facilitating a thinner and lighter design. Furthermore, the fast response of shape memory metal improves the stabilization effect of the camera module, and since no magnetic field is required during stabilization, it does not cause magnetic interference to other electronic components in the device, thereby improving the imaging effect of the camera module.
[0013] In some embodiments of this utility model, the second elastic connector includes: a third fixing piece disposed on the second end face of the bracket; a fourth fixing piece disposed on the end face of the base opposite to the bracket, wherein the end face of the base opposite to the bracket is the third end face; and a first elastic member connected between the third fixing piece and the fourth fixing piece, wherein there are two third fixing pieces and two fourth fixing pieces, and four first elastic members are provided. Along the circumferential direction, two third fixing pieces and two fourth fixing pieces are arranged alternately, and the first elastic members are connected between adjacent third fixing pieces and fourth fixing pieces. Therefore, while meeting the carrier's image stabilization requirements, it can provide a relatively uniform force, thereby giving the carrier better stability during image stabilization, which is beneficial to improving the imaging quality of the camera module.
[0014] In some embodiments of this invention, a first fixing block is provided on the second end face. The side of the first fixing block facing away from the bracket is coplanar with the third end face. A portion of the third fixing piece extends to the third end face and overlaps it to restrict the relative position of the bracket and the base in the axial direction. Thus, the position of the third fixing piece in the optical axis direction can be adjusted by the first fixing block, allowing the third fixing piece to partially overlap the third end face. In this way, when the bracket vibrates relative to the base, the contact between the surfaces allows the bracket to move better in the direction perpendicular to the optical axis, resulting in good stability.
[0015] In some embodiments of this utility model, the end face of the base facing away from the third end face is a fourth end face. The anti-shake mechanism further includes a third elastic connector, which comprises: a fifth fixing plate disposed on the second fixing block on the fourth end face; and a second elastic member, one end of which is connected to the fifth fixing plate and the other end of which is connected to the bracket. Two second elastic members are provided, each extending along one of the two outer peripheral surfaces of the bracket and connected to the bracket. Therefore, when the bracket shakes relative to the base, the third elastic connector can effectively balance the force of the second elastic connector, making the relative movement of the bracket more stable.
[0016] In some embodiments of this invention, two second elastic members are provided, with two fifth fixing plates and two fourth fixing plates respectively arranged axially. Therefore, when the bracket vibrates relative to the base, each third elastic connector can balance the force of the second elastic connector in two different directions, making the relative movement of the bracket more stable.
[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] The following is for reference. Figures 1-3 A camera module 100 according to an embodiment of the present utility model is described.
[0036] The camera module 100 according to an embodiment of the present invention includes a focusing mechanism, such as... Figures 1-2 As shown, the focusing mechanism includes a carrier 1, a lens assembly, a support 2, a drive assembly 3, and a guide assembly 4. The lens assembly is mounted on the carrier 1. The support 2 is a ring-shaped support that is sleeved on the outer periphery of the carrier 1. The drive assembly 3 includes a coil 31 and a magnet 32. The coil 31 is mounted on the support 2, and the magnet 32 is mounted on the carrier 1. When the coil 31 is energized, it drives the magnet 32, causing the magnet 32 to move the carrier 1. The guide assembly 4 includes a guide rail 41 and a guide groove 42. The guide rail 41 is mounted on the support 2, and the guide groove 42 is mounted on the carrier 1. The guide rail 41 and the guide groove 42 cooperate with each other to guide the movement direction of the carrier 1.
[0037] In other words, the guide assembly 4 employs a design where the guide rail 41 and guide groove 42 work together to provide a relatively stable guiding effect for the movement of the carrier 1. This stability makes the focusing mechanism less susceptible to interference from changes in external temperature and humidity. Whether in hot and humid environments or in rainy and humid climates, it ensures precise focusing of the lens assembly and guarantees clear and stable image quality.
[0038] Meanwhile, due to its stable guiding effect, the focusing mechanism is not prone to failure due to fatigue or wear during long-term use. Even after a large number of focusing operations, the fit between the guide rail 41 and the guide groove 42 remains tight, and the movement direction of the carrier 1 can always be relatively precise and controllable. This can effectively extend the service life of the camera module 100, reduce the maintenance or replacement costs caused by focusing mechanism failure, and ensure high reliability and good stability.
[0039] For example, the lens assembly includes at least one lens, which may be a glass lens or a plastic lens, and this application does not limit the scope of the lens assembly.
[0040] For example, magnet 32 can be a magnet, and two magnets are provided, see reference. Figure 1 and Figure 2 As shown, two magnets can be respectively set on the left and right sides of the carrier 1. Similarly, two coils 31 are provided, with the two coils 31 respectively set on the left and right sides of the carrier 1, and the two coils 31 and the two magnets are respectively set in correspondence. Thus, after the coil 31 is energized, it can generate magnetic induction force, thereby driving the magnet to move along the optical axis and thus adjusting the focal length of the camera module 100.
[0041] According to the embodiment of this utility model, the camera module 100, by setting a guide component 4 in which the guide rail 41 and the guide groove 42 cooperate with each other, can provide a relatively stable guiding effect for the movement of the carrier 1, making the focusing mechanism less susceptible to interference from changes in external temperature and humidity. Whether in hot and humid environments or in rainy and humid climates, it can ensure accurate focusing of the lens assembly, guaranteeing clear and stable image quality, and can significantly extend the service life of the camera module 100, reducing repair or replacement costs due to focusing mechanism failures. It exhibits high reliability and good stability.
[0042] In some embodiments of this utility model, such as Figures 1-2 As shown, the guide rail 41 includes a protrusion protruding from the inner circumferential surface of the bracket 2, and the guide groove 42 includes a recessed portion on the outer circumferential surface of the carrier 1. The protrusion and the recess are interlocked.
[0043] For example, multiple protrusions may be provided, and the multiple protrusions are spaced apart along the inner peripheral surface of the support 2. Similarly, multiple recesses may be provided, and the multiple recesses are spaced apart along the outer peripheral surface of the carrier 1.
[0044] In the above example, the interlocking of the convex and concave parts allows the carrier 1 to be relatively stably positioned when it moves along the optical axis, reducing or even eliminating the shaking of the carrier 1 and providing a relatively stable guiding effect for the carrier 1. Furthermore, the interlocking of the convex and concave parts makes the connection between the carrier 1 and the bracket 2 relatively tight, so that the camera module 100 can still guide the carrier 1 relatively stably during long-term use, and further reduces the interference of external temperature and humidity changes, thereby ensuring accurate focusing of the lens assembly and ensuring clear and stable image quality.
[0045] In some embodiments of this utility model, such as Figures 1-2 As shown, the guide rail 41 also includes a guide shaft 43 disposed between the protrusion and the recess, and the guide shaft 43 is fixed on the bracket 2.
[0046] refer to Figure 1 and Figure 2 In one example, the convex portion has a groove on its side facing the concave portion, which extends through the convex portion along the optical axis. A guide shaft 43 is disposed within the groove. The guide shaft 43 can be a cylindrical shaft, and one end of the guide shaft 43 can be fixedly connected to the bracket 2. For example, the guide shaft 43 can be welded to the bracket 2. This application does not limit the connection method. By providing the guide shaft 43 within the groove, the guide shaft 43 can space the side of the convex portion with the groove from the corresponding side of the concave portion. This can effectively increase the allowable error during manufacturing of the convex and concave portions, thereby reducing the processing difficulty of the bracket 2 and the carrier 1. Furthermore, it can also reduce the assembly difficulty when assembling the carrier 1 and the bracket 2, thereby improving assembly efficiency.
[0047] In some embodiments of this utility model, such as Figures 1-2 As shown, there are two guide rails 41 and two guide grooves 42. The two guide rails 41 are respectively matched with the two guide grooves 42, and the two guide grooves 42 are respectively located on both sides of the carrier 1.
[0048] like Figures 1-2 As shown, each of the two guide rails 41 has a groove, and each groove has a guide shaft 43. The axis of the guide shaft 43 is parallel to the optical axis, and the axes of the two guide shafts 43 are coplanar with the optical axis. That is, the two guide shafts 43 are located on both sides of the carrier 1. This arrangement makes the carrier 1 more stable when it moves along the optical axis.
[0049] In some embodiments of this utility model, such as Figures 1-2 As shown, the camera module 100 also includes: a first elastic connector 51, one end of which is connected to the end face of the bracket 2, and the other end is connected to the end face of the carrier 1 through a first fixing piece 52. There are two first elastic connectors 51, and the two first fixing pieces 52 and the two guide rails 41 are arranged alternately along the circumference of the carrier 1.
[0050] like Figures 1-2 As shown, in the projection plane perpendicular to the optical axis, the projection shape of the carrier 1 is approximately octagonal, with two concave portions located on opposite sides of the octagon. Similarly, the two first fixing pieces 52 are also close to opposite sides of the octagon. In the circumferential direction, the two first fixing pieces 52 and the two guide rails 41 are arranged in a manner that is approximately evenly spaced apart.
[0051] Furthermore, the connection position of the first elastic connector 51 to the bracket 2 is close to the protrusion. Thus, when the driving component 3 drives the carrier 1 to move along the optical axis, the cooperation of the protrusion and the concave part, as well as the first elastic connector 51, enables the carrier 1 to move more stably and can better balance the force of the carrier 1 in the circumferential direction, making the carrier 1 less prone to shaking when moving along the optical axis, thereby improving the imaging quality of the camera module 100.
[0052] In some embodiments of this utility model, such as Figures 1-3 As shown, the bracket 2 has a first end face 21 and a second end face 22 facing away from each other. One end of the first elastic connector 51 is connected to the first end face 21. The camera module 100 also includes a stabilization mechanism, which includes a base 6 and a second elastic connector 7. The base 6 is disposed on the second end face 22 of the bracket 2. The second elastic connector 7 is connected between the base 6 and the bracket 2 so that the bracket 2 can move radially relative to the base 6. At least a portion of the second elastic connector 7 is made of shape memory metal so that the second elastic connector 7 can deform after being energized.
[0053] In other words, the two end faces of the bracket 2 along the optical axis are the first end face 21 and the second end face 22, respectively. By setting the first elastic connector 51 on the first end face 21 of the bracket 2 and setting the base 6 and the second elastic connector 7 on the second end face 22 of the bracket 2, the image stabilization mechanism and the focusing mechanism are less likely to interfere with each other.
[0054] Furthermore, since at least a portion of the second elastic connector 7 is composed of shape memory metal, enabling it to deform upon energization, it should be noted that shape memory metal possesses unique shape memory effect and superelastic properties. When at least a portion of the second elastic connector 7 is composed of shape memory metal, energization causes the current to pass through the shape memory metal, generating Joule heating and raising its temperature. Upon reaching a specific transition temperature range, the internal crystal structure of the shape memory metal changes, transforming from one crystal structure to another, resulting in macroscopic deformation. Under the influence of the shape memory effect, the shape memory metal recovers its pre-set shape, achieving the deformation of the second elastic connector 7. Controlling the deformation of the second elastic connector 7 by energization provides a more flexible and precisely controllable deformation effect compared to traditional elastic connectors.
[0055] Therefore, in this invention, by using shape memory metal to drive the carrier 1 to respond to shake compensation requirements, the complex coil 31 and magnet structure can be eliminated, which helps to simplify the structure of the camera module 100, thereby reducing the size and weight of the camera module 100 and facilitating its thinner and lighter design. Furthermore, the shape memory metal has a fast response speed, which can also improve the image stabilization effect of the camera module 100. Moreover, no magnetic field is required during the image stabilization process, so it will not cause magnetic interference to other electronic components (such as sensors) in the device, thus improving the imaging effect of the camera module 100.
[0056] In some embodiments of this utility model, such as Figures 1-3 As shown, the second elastic connector 7 includes a third fixing piece 71, a fourth fixing piece 72, and a first elastic member 73. The third fixing piece 71 is disposed on the second end face 22 of the bracket 2, and the fourth fixing piece 72 is disposed on the end face of the base 6 away from the bracket 2. The end face of the base 6 away from the bracket 2 is the third end face 61. The first elastic member 73 is connected between the third fixing piece 71 and the fourth fixing piece 72. There are two third fixing pieces 71 and two fourth fixing pieces 72, and four first elastic members 73. Along the circumferential direction, two third fixing pieces 71 and two fourth fixing pieces 72 are arranged alternately, and the first elastic member 73 is connected between adjacent third fixing pieces 71 and fourth fixing pieces 72.
[0057] like Figure 3In the example shown, the side of the base 6 away from the bracket 2 is rectangular. There are two third fixing pieces 71, which are close to the two ends of one diagonal. There are two fourth fixing pieces 72, which are close to the two ends of the other diagonal. The first elastic element 73 can be made of shape memory metal. The first elastic element 73 is ribbed and there are four of them. The four first elastic elements 73 are parallel to the four sides of the side of the base 6 away from the bracket 2. This not only improves the aesthetics of the camera module 100, but also provides a relatively uniform force while meeting the image stabilization requirements of the carrier 1. This makes the carrier 1 more stable during image stabilization, thereby improving the imaging quality of the camera module 100.
[0058] Exemplarily, the fourth fixing piece 72 includes two spaced-apart sub-fixing pieces. For ease of description, these four sub-fixing pieces are referred to as the first sub-fixing piece 721, the second sub-fixing piece 722, the third sub-fixing piece 723, and the fourth sub-fixing piece 724, respectively. The first sub-fixing piece 721 is connected to a third fixing piece 71 via a first elastic member 73. This third fixing piece 71 is connected to the fourth sub-fixing piece 724 via another first elastic member 73, thereby constructing one anti-shake driving unit. Similarly, the second sub-fixing piece 722 is connected to another third fixing piece 71 via a first elastic member 73. This third fixing piece 71 is connected to the third sub-fixing piece 723 via another first elastic member 73, thereby constructing another anti-shake driving unit. The two anti-shake driving units can better balance the force exerted on the carrier 1 during shaking, making the carrier 1 more stable. In this example, the connection method can be welding, and this application does not limit this.
[0059] In some embodiments of this utility model, such as Figures 1-3 As shown, the second end face 22 is provided with a first fixing block 23. The side of the first fixing block 23 away from the bracket 2 is coplanar with the third end face 61. A portion of the third fixing piece 71 extends to the third end face 61 and is stacked on the third end face 61 to limit the relative position of the bracket 2 and the base 6 in the axial direction.
[0060] In other words, the position of the third fixing piece 71 in the optical axis direction can be adjusted by the first fixing block 23, so that the third fixing piece 71 can be partially stacked on the third end face 61. In this way, when the bracket 2 shakes relative to the base 6, the contact between the surfaces allows the bracket 2 to move better in the direction perpendicular to the optical axis, resulting in good stability.
[0061] In some embodiments of this utility model, such as Figures 1-3As shown, the end face of the base 6 facing away from the third end face 61 is the fourth end face 62. The anti-shake mechanism also includes a third elastic connector 8, which includes a fifth fixing piece 81 and a second elastic piece 82. The fifth fixing piece 81 is disposed on the second fixing block 63 of the fourth end face 62. One end of the second elastic piece 82 is connected to the fifth fixing piece 81, and the other end is connected to the bracket 2. There are two second elastic pieces 82, which extend along the two outer peripheral surfaces of the bracket 2 and are connected to the bracket 2.
[0062] In other words, when the bracket 2 vibrates relative to the base 6, the force of the second elastic connector 7 can be better balanced by the third elastic connector 8, making the relative movement of the bracket 2 more stable.
[0063] In some embodiments of this utility model, such as Figures 1-3 As shown, there are two second elastic members 82, with two fifth fixing pieces 81 and two fourth fixing pieces 72 respectively arranged along the axial direction. Therefore, when the bracket 2 vibrates relative to the base 6, each third elastic connector 8 can balance the force of the second elastic connector 7 in two different directions, making the relative movement of the bracket 2 more stable.
