Description

Technical Field

Background

Photos shot by electronic equipment such as a mobile phone and the like in the shooting process sometimes become blurred, namely, the shot pictures are not clear enough, and the condition of double images or blurring occurs. These causes are largely due to slight shaking occurring when a photographic subject is exposed, in addition to occasional defocus (i.e., the imaging lens is not in normal focus). In general, such a very slight shaking phenomenon often occurs in a handheld condition, and thus, in recent years, there is a relatively large demand for developing an anti-shaking function. Under the background, proposals for the optical anti-shake function of OIS (optical image stabilization system) are increasing, and the micro optical anti-shake technology is gradually adopted by various high-end mobile phones, so that it is expected to effectively reduce the probability of taking blurred pictures in a low-light environment and effectively solve the trouble caused by hand shake in the shooting process. However, compared to a general auto-focus motor, the design of the OIS optical anti-shake apparatus is complicated, and the production efficiency and yield are low, so the development is difficult.

In the existing OIS, due to the complexity of the structure, the anti-shake thrust is not strong enough, and the service performance of the OIS is further influenced. Therefore, the problem that the anti-shake thrust performance of the anti-shake structure is poor exists in the prior art.

In order to solve the problem that anti-shake thrust performance of an anti-shake structure is poor in the prior art, the application provides an anti-shake structure, an anti-shake system and a camera device.

The camera device comprises an anti-shake system, and the anti-shake system comprises an anti-shake structure. Through using the anti-shake system in this application, can improve camera device's anti-shake performance effectively, avoid appearing using camera device to shoot out fuzzy, unclear image.

As shown in fig. 1 to 12, the anti-shake structure according to the present invention includes a housing 10, a lens support body 20, a driving coil 30, a flexible FPC board 40, a support frame 60, a plurality of driving magnets 70, and a base 80. The driving coil 30 is provided on the lens support body 20 around the circumferential direction of the lens support body 20; the flexible FPC board 40 is disposed around the circumferential inner side wall of the housing 10 and has a plurality of lateral coils 50; the supporting frame 60 is located between the lens supporting body 20 and the flexible FPC board 40, and a plurality of side walls of the supporting frame 60 corresponding to the lateral coils 50 are provided with mounting notches 61; the driving magnets 70 are arranged on the mounting notches 61 so that the plurality of lateral coils 50 are arranged corresponding to the plurality of driving magnets 70; a part of the electrical conduction structure 90 is embedded inside the base 80, and another part of the electrical conduction structure 90 protrudes from the base 80 to form a terminal portion or is electrically connected to the flexible FPC board 40.

When using the anti-shake structure of above-mentioned structure, because the electric conductance of establishing in the inside of base 80 and can realizing with flexible FPC board 40 is established to partly the inlay of electric conductance structure 90 to no longer need set up the FPC board and realize the electric conductance between end foot and flexible FPC board 40 between base 80 and lens support body 20 and lead to, and then not only simplified the inner structure of anti-shake structure but also can make the anti-shake structure more frivolous. And by disposing the flexible FPC board 40 around the circumferential inner side wall of the housing 10, and disposing the side coil 50 on the flexible FPC board 40, the side coil 50 is disposed in correspondence with the plurality of driver magnets 70. Thus, when the flexible FPC board 40 is electrically connected to the lateral coil 50, the lateral coil 50 can be disposed in the lateral direction of the driver magnet 70 instead of the bottom surface of the driver magnet 70, so that the effective acting area between the lateral coil 50 and the driver magnet 70 is greatly increased, and thus, not only can a larger lateral thrust be provided by the lateral coil 50, but also the height space occupied by the anti-shake structure can be reduced, which is more favorable for the product thinning structure. Due to the excellence of the driving effect, the basic requirement of the driving force of the product is met, and the possibility of more development is further provided for the miniaturization, light weight and thin modification of the whole volume of the product. Furthermore, since the mounting notch 61 is formed in the supporting frame 60, the inductive distance between the driving magnet 70 and the side coil 50 is effectively reduced, so that the driving magnet 70 and the side coil 50 can be closer to each other. Meanwhile, the thickness of the driving magnet 70 can be further increased, so that the magnetic field intensity is improved, and the anti-shake thrust is enhanced. Consequently, the anti-shake structure in this application has solved the poor problem of anti-shake structure anti-shake thrust performance among the prior art effectively.

Specifically, the drive magnet 70 has mounting slopes 71 at both ends thereof, and the support frame 60 has a catching slope 612 to be fitted with the mounting slopes 71. Through setting up like this, can guarantee effectively that drive magnetite 70 can install more stably on braced frame 60 to guarantee effectively that relative rocking can not appear between drive magnetite 70 and the braced frame 60.

Specifically, the mounting slope 71 is provided on the side of the drive magnet 70 away from the lens support body 20. With such a configuration, it is possible to ensure that the drive magnet 70 is smoother toward one side of the lens support body 20, so that it is possible to ensure that the drive magnet 70 does not affect the movement of the lens support body 20, and it is possible to effectively ensure that the internal structure of the anti-shake structure is more compact by such a configuration.

Preferably, both ends of the mounting notch 61 have mounting grooves 611, respectively, both ends of the driving magnet 70 extend into the mounting grooves 611, respectively, and a groove wall of the mounting groove 611 has an overlapping inclined surface 612. This can further enhance the stability of the connection between the drive magnet 70 and the support frame 60, and prevent looseness between the drive magnet 70 and the support frame 60.

In addition, in the present application, the connection effect between the support frame 60 and the drive magnet 70 can be enhanced by performing the dispensing process at the position of the support frame 60 corresponding to the drive magnet 70, so as to ensure the stability between the support frame 60 and the drive magnet 70.

Specifically, one end of the support frame 60 away from the base 80 has a stopper projection 62, and the drive magnet 70 abuts against the stopper projection 62. In an embodiment of the present application, the number of the driving magnets 70 is four, so when the four driving magnets 70 are installed, the driving magnets 70 can be respectively abutted against the corresponding stopping protrusions 62, so that it is ensured that the four driving magnets 70 can be located at the same height, and the usability of the anti-shake structure is effectively ensured.

Specifically, the corner of the supporting frame 60 on the side away from the base 80 has a limiting groove 63, and the side of the lens supporting body 20 away from the base 80 is correspondingly provided with a limiting protrusion 21 matched with the limiting groove 63.

Specifically, the stopper groove 63 extends upward and penetrates the top surface of the support frame 60.

Optionally, the stop protrusion 21 projects laterally away from the center of the lens support 20.

Set up like this, through spacing groove 63 and spacing protruding 21's cooperation, can prevent effectively that the collision from appearing between lens supporter 20 and the base 80 to can guarantee effectively the stability of anti-shake structure, and further guarantee the anti-shake effect of anti-shake structure.

With this arrangement, not only the coil lead group 92 can be electrically connected to the lateral coil 50 on the flexible FPC board 40 through the communication member 91, but also the entire structure of the anti-shake structure can be effectively reduced since a part of the communication member 91 is embedded inside the chassis 80. And also effectively prevents the communication member 91 from coming into contact with the lens support 20.

Specifically, the communicating member 91 is close to the lens support body 20 with respect to the coil lead group 92. That is, in the present application, the communicating member 91 and the coil pin group 92 are not in the same plane, and by such arrangement, the communicating member 91 can be more flexibly arranged, and the short circuit between the coil pin groups 92 can be effectively avoided.

Preferably, the coil pin group 92 includes a plurality of coil pins, at least one of the coil pins has a two-layer structure in the axial direction of the lens support body 20, and the coil pins having the two-layer structure are formed by bending in an integral structure.

Specifically, the coil pins in the two-layer structure are bent and then extended to the outside of the base 80 to form the terminal portions.

Specifically, the communicating assembly 91 includes a plurality of communicating bodies connected in one-to-one correspondence with the plurality of coil pins, and the communicating bodies are connected to the middle portions of the coil pins. Through setting up like this, can make things convenient for the connector to be connected with the coil pin more to guarantee effectively that the connection between connector and the coil pin is more stable.

Specifically, a plurality of welding grooves 41 are formed in a set of two opposite side walls of the flexible FPC board 40, the plurality of welding grooves 41 correspond to the plurality of lateral coils 50, the flexible FPC board 40 and the base 80 are welded by the welding grooves 41 and the communication component 91 to realize electrical connection between the lateral coils 50 and the coil pin set 92, and an avoidance opening is formed in a position of the housing 10 corresponding to the welding grooves 41.

Specifically, the electrical connection paths between the coil pin set 92, the communication assembly 91 and the lateral coil 50 are: the first coil pin 921 or the second coil pin 922 → the first via 911 or the second via 912 → the lateral coil 50 → the third via 913 or the fourth via 914 → the third coil pin 923 or the fourth coil pin 924. In the present application, the number of the lateral coils 50 is 4, and two sets of the lateral coils 50 are oppositely disposed, so that two sets of the lateral coils 50 exist together, and the first coil pin 921 and the third coil pin 923 are connected in series with one set of the lateral coils 50, and the second coil pin 922 and the fourth coil pin 924 are connected in series with the other set of the lateral coils 50.

By such an arrangement, the coil lead group 92 and the communication component 91 can be distributed more uniformly inside the base 80. And through setting up like this still can guarantee effectively that the density value of base 80 everywhere is more even to the in-process base 80 that can guarantee the anti-shake structure work is more balanced.
