Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to an optical image stabilization and collision prevention structure. Background Technology

[0002] In recent years, optical image stabilization (OIS) technology has become a core support for achieving high-quality imaging in smartphones, drones, and portable imaging devices. As consumers' demands for image clarity, low-light shooting, and dynamic video stability increase, the miniaturization, high-frequency response, and shock resistance of OIS motors face greater challenges. Especially in environments involving device drops, rapid zooming, or extreme temperatures, the structural reliability defects of traditional OIS motors are becoming increasingly apparent. Among these, the issue of impact-related foreign objects has become an industry pain point restricting product yield and user experience.

[0003] Most mainstream OIS motors currently employ a cantilever support structure, using electromagnetic drive via coils and magnets to compensate for lens displacement. To limit lens displacement overtravel, a plastic impact boss is typically placed between the substrate and the movable frame. However, traditional designs use injection molding to integrally mold the boss and substrate, typically using rigid engineering plastics (such as PBT or LCP). This rigid connection lacks a buffering mechanism between the boss and the movable frame when subjected to high-frequency impacts, causing stress concentration at the contact point. This makes the boss prone to wear and debris release during collisions, severely impacting camera shooting. Utility Model Content

[0004] To address the shortcomings of the existing technology, the technical problem to be solved by this utility model is: to propose an optical image stabilization and anti-collision structure and an OIS motor, which utilizes a detachable impact platform and an impact groove to allow the impact platform to be selected according to actual needs, thereby making the impact range adjustable and thus meeting different image stabilization and focusing stroke requirements.

[0005] One technical solution adopted by this utility model is: providing an optical image stabilization and anti-collision structure, including a base, and further comprising:

[0006] A flexible circuit board is fixed to the top surface of the base;

[0007] A carrier is disposed on the top of the flexible circuit board; at least two first impact components are uniformly arranged circumferentially on the bottom of the carrier for absorbing the impact between the carrier and the flexible circuit board; at least two second impact components are uniformly arranged circumferentially on the top of the carrier for absorbing the impact between the carrier and the carrier support.

[0008] A carrier support is sleeved on the outside of the carrier; each side of the carrier support is provided with at least one third impact component for absorbing the impact between the carrier support and the side of the outer frame; at least two fourth impact components are uniformly arranged circumferentially on the top of the carrier support for absorbing the impact between the carrier support and the top surface of the outer frame.

[0009] An outer frame is fitted onto the base and houses the flexible circuit board, carrier, and carrier support within the outer frame.

[0010] Furthermore, the first impact assembly includes a first impact groove evenly opened circumferentially at the bottom of the carrier, and a first impact platform detachably placed in the first impact groove.

[0011] Furthermore, the number of the first impact grooves is four; when the anti-shake and anti-collision structure is stationary, all the first impact platforms have the same height, and the distance between the first impact platform and the flexible circuit board is the first focusing stroke.

[0012] Furthermore, the second impact assembly includes a second impact groove evenly opened circumferentially on the top of the carrier, and a second impact platform detachably placed in the second impact groove.

[0013] Furthermore, the number of the second impact grooves is four; when the anti-shake and anti-collision structure is in a static state, the height of the second impact platform is lower than the top surface of the carrier support, and the distance between all the second impact platforms and the corresponding inner top wall on the outer frame is equal, and this distance is the first anti-shake stroke.

[0014] Furthermore, the third impact assembly includes a third impact groove formed on each side of the carrier support, and a third impact platform detachably placed in the third impact groove.

[0015] Furthermore, the number of the third impact grooves is eight, and two are provided on each outer side of the carrier bracket; when the anti-shake and anti-collision structure is in a static state, the distance between all the third impact platforms and the corresponding inner sidewalls on the outer frame is equal, and this distance is the second anti-shake stroke.

[0017] Furthermore, the number of the fourth impact grooves is eight; when the anti-shake and anti-collision structure is stationary, the distance between all the fourth impact platforms and the top of the inner wall of the outer frame is equal, and this distance is the second focusing stroke.

[0018] Another technical solution adopted by this utility model is: an OIS motor, which adopts the optical image stabilization and anti-collision structure as described in any one of the above-mentioned methods.

[0019] The optical image stabilization and anti-collision structure and OIS motor of this utility model have at least the following beneficial effects: 1.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] Please see Figures 1-6 This embodiment specifically describes an optical image stabilization and anti-collision structure, which may include a base 1, a flexible circuit board 2, a carrier 3, a carrier support 4, and an outer frame 5. The flexible circuit board 2 can be fixed to the top surface of the base 1. The carrier 3 can be disposed on the top of the flexible circuit board 2; at least two first impact components 31 are uniformly arranged circumferentially on the bottom of the carrier 3 to absorb the impact between the carrier 3 and the flexible circuit board 2; at least two second impact components 32 are uniformly arranged circumferentially on the top of the carrier 3 to absorb the impact between the carrier 3 and the carrier support 4. The carrier support 4 can be sleeved on the outside of the carrier 3; at least one third impact component 41 is arranged on each side of the carrier support 4 to absorb the impact between the carrier support 4 and the side of the outer frame 5; at least two fourth impact components 42 are uniformly arranged circumferentially on the top of the carrier support 4 to absorb the impact between the carrier support 4 and the top surface of the outer frame 5; the outer frame 5 is sleeved on the base 1 and houses the flexible circuit board 2, the carrier 3, and the carrier support 4 within the outer frame 5.

[0031] The optical image stabilization and collision avoidance structure of this embodiment differs from traditional optical image stabilization and collision avoidance structures by replacing the traditional impact platform integrally formed with the carrier 3 or carrier support 4 with an impact assembly. The structures of the base 1, flexible circuit board 2, carrier 3, carrier support 4, and outer frame 5 are similar to those of traditional optical image stabilization and collision avoidance structures, such as... Figure 1 and Figure 2As shown, the flexible circuit board 2 can be fixed on the base 1; the carrier 3 is used to support the lens and is placed on top of the flexible circuit board 2, and the two are subjected to impact by the first impact component 31; the carrier support 4 is sleeved on the outside of the carrier 3 (the connection between the two can be achieved by a guide mechanism, elastic structure support, or electromagnetic drive coupling. The above connection methods are commonly used in existing optical image stabilization and anti-collision structures, and will not be described in detail in this solution, nor shown in the attached figure). Similar to the first impact component 31, each side of the carrier support 4 is provided with at least one third impact component 41 to absorb the impact between the carrier support 4 and the side of the outer frame 5. At the same time, at least two fourth impact components 42 are evenly arranged on the top of the carrier support 4 along the circumference to absorb the impact between the carrier support 4 and the top surface of the outer frame 5. The outer frame 5 is equivalent to a shell that can be sleeved on the base 1 and accommodate the flexible circuit board 2, the carrier 3, and the carrier support 4 inside, thus providing protection.

[0032] Please see Figures 3-5 In the illustrated embodiment, the first impact component 31 includes a first impact groove 311 evenly opened circumferentially along the bottom of the carrier 3, and a first impact platform 312 detachably placed in the first impact groove 311. This solution replaces the traditional one-piece molded anti-collision boss with an impact component, and the first impact component 31 is set at the bottom of the carrier 3. It may include the first impact groove 311 evenly opened circumferentially along the bottom of the carrier 3, and the first impact platform 312 detachably placed in the first impact groove 311. It should be noted that the first impact platform 312 and the first impact groove 311 can be bonded together with adhesive, so that the size of the first impact platform 312 can be selected according to actual needs.

[0033] The number of the first impact grooves 311 is four; when the anti-shake and anti-collision structure is stationary, all the first impact platforms 312 have the same height, and the distance between the first impact platform 312 and the flexible circuit board 2 is the first focusing stroke. In order to further improve the impact resistance of the first impact assembly 31, the number of the first impact grooves 311 can be set to four, and they can be evenly distributed along the bottom edge of the carrier 3. Then, the distance between the first impact platform 312 placed in the first impact groove 311 and the flexible circuit board 2 can be used as the first focusing stroke, that is, the AF down stroke.

[0034] Similarly, the second impact assembly 32 may include a second impact groove 321 uniformly opened circumferentially on the top of the carrier 3, and a second impact platform 322 detachably placed in the second impact groove 321. The effects of the second impact groove 321 and the second impact platform 322 are similar to those of the first impact assembly 31.

[0035] The number of the second impact grooves 321 can also be set to four; when the anti-shake and anti-collision structure is stationary, the height of the second impact platform 322 is lower than the top surface of the carrier support 4. In addition, all the second impact platforms 322 are equidistant from the corresponding inner top wall on the outer frame 5, and this distance is the first anti-shake stroke, that is, the OIS anti-shake stroke in the optical path direction.

[0036] Please see Figure 6 In the embodiment shown, the third impact assembly 41 includes a third impact groove 411 formed on each side of the carrier support 4, and a third impact platform 412 detachably placed in the third impact groove 411.

[0037] The number of the third impact grooves 411 is eight, and two are opened on each outer side of the carrier bracket 4; when the anti-shake and anti-collision structure is in a static state, the distance between all the third impact platforms 412 and the corresponding inner sidewalls on the outer frame 5 is equal, and this distance is the second anti-shake stroke, that is, the anti-shake stroke perpendicular to the optical path direction.

[0038] The fourth impact assembly 42 includes at least two fourth impact grooves 421 evenly opened circumferentially on the top of the carrier support 4, and a fourth impact platform 422 detachably placed in the fourth impact grooves 421.

[0039] The number of the fourth impact grooves 421 is eight; when the anti-shake and anti-collision structure is stationary, all the fourth impact platforms 422 are equidistant from the top of the inner wall of the outer frame 5, and this distance is the second focusing stroke, that is, the AF upper stroke.

[0040] It should be noted that the connection method between the impact groove and the impact platform in the second impact assembly 32, the third impact assembly 41 and the fourth impact assembly 42 is the same as the connection method between the first impact platform 312 and the first impact groove 311. They can all be detached and installed using glue. Therefore, the size of each impact platform can be selected according to actual needs, so that it can be suitable for different image stabilization strokes and focusing strokes.

[0041] This utility model also provides an OIS motor, which adopts the optical image stabilization and anti-collision structure as described in any of the above.

[0042] This utility model provides an optical image stabilization and anti-collision structure that allows for the detachable installation of the impact platform and impact groove. This enables the impact platform to be made of silicone or soft plastic instead of conventional carrier materials, reducing the problem of debris generation under continuous impact. Furthermore, the impact platform's size can be selected according to actual needs, making the impact range adjustable to meet different image stabilization and focusing strokes. The use of silicone or soft plastic instead of conventional carrier materials eliminates the need for the impact platform to be recessed at the edge of the outer frame 5 or base 1, thus greatly improving the feasibility and design space of the structure.

[0043] The above description merely illustrates preferred embodiments of the present invention and is quite specific and detailed; however, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
