Description

Technical Field

[0002] In a camera module, the direction of the imaging light projected onto the image sensor chip is typically set perpendicular to the photosensitive surface of the image sensor chip. To achieve compensation and correction capabilities for shooting shake, a stabilization mechanism is usually configured to move the lens or image sensor chip to improve the quality of image-stabilized shooting.

[0003] In the process of moving the image sensor chip in the image stabilization mechanism, the image sensor chip is prone to random changes in spatial orientation, which causes the angle between the photosensitive surface of the image sensor and the imaging light rays projected onto the photosensitive surface to change. That is, the angle between the photosensitive surface and the imaging light rays will change dynamically instead of remaining in a 90-degree orthogonal state, resulting in unsatisfactory image quality. Summary of the Invention

[0004] This application provides an image stabilization mechanism and a camera module, aiming to at least partially solve the technical problem of dynamic tilt during chip movement in camera modules that use chip-based image stabilization, thereby improving the stability of chip-based image stabilization and image quality. Therefore,

[0016] In some embodiments, the opening of the rolling groove is configured as a spherical arc surface that matches the ball, and the ball rollably abuts against the spherical arc surface so that the ball rolls in place within the rolling groove.

[0017] In some embodiments, the number of the ball bearings, the attraction pad, and the attraction magnet are all three, and the line connecting the three ball bearings forms an isosceles triangle.

[0018] In some embodiments, the chip carrier is rectangular, and one of the two parallel rectangular sides of the chip carrier has a ball bearing abutted at the middle of one rectangular side and a ball bearing abutted at each end of the other rectangular side.

[0026] The image stabilization mechanism and camera module provided in this application include a magnet bracket, a driving magnet, a chip carrier, a driving coil, and a rolling support assembly.

[0035] 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.

[0036] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes 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; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0037] This application is described below with reference to the accompanying drawings and specific embodiments:

[0038] In some camera modules equipped with chip-driven image stabilization mechanisms, the image sensor chip is configured to be movable. To drive the image sensor chip's movement, a driving mechanism is often formed by a matching driving magnet and a driving coil. This mechanism utilizes the principle that an energized coil moves under the force of a magnetic field. However, during the movement of the image sensor chip, it is affected by various factors such as driving force and vibration, causing spatial attitude changes such as unilateral tilting or sinking, which affects image quality.

[0039] Therefore, this application provides a stabilization mechanism and a camera module, which aims to solve the problem of chip tilting on one side and other changes in movement posture during chip-based image stabilization to a certain extent, thereby achieving the technical effect of maintaining the posture of the image sensor chip during image stabilization operation and improving the image stabilization shooting quality.

[0040] See Figure 1 and Figure 2In some embodiments, the image stabilization mechanism may include a magnet support 1, a chip carrier 2, an image stabilization drive mechanism 3, and a rolling support assembly 4. The chip carrier 2 is movably placed inside the magnet support 1 via the rolling support assembly 4, and the distance between the chip carrier 2 and the magnet support 1 is maintained. The drive mechanism 3 is connected between the magnet support 1 and the chip carrier 2 to drive the chip carrier 2 to move relative to the magnet support 1.

[0041] The magnet bracket 1 serves as the foundation for the image stabilization mechanism to perform its stabilization operation, housing and supporting the chip carrier 2, the image stabilization drive mechanism 3, and the rolling support assembly 4. Furthermore, when the image stabilization mechanism is assembled into the camera module, the magnet bracket 1 can be installed and fixed within the camera module to facilitate the installation of the chip carrier 2, the image stabilization drive mechanism 3, and the rolling support assembly 4.

[0042] The chip carrier 2 can serve as a carrier for the image sensing chip and is movably disposed within the magnet bracket 1. Thus, when the image sensing chip is assembled on the chip carrier 1, the image sensing chip can move relative to the magnet bracket 1 along with the chip carrier 2, thereby achieving chip motion stabilization.

[0043] The driving mechanism 3 may include a driving magnet 31 and a driving coil 32, which are respectively mounted on the magnet support 1 and the chip carrier 2. The positions of the driving magnet 31 and the driving coil 32 are matched such that the driving coil 32 is located within the magnetic field range of the driving magnet 31. Therefore, when the driving coil 32 is energized, an interaction force is generated between the energized driving coil 32 and the driving magnet 31, which can serve as an anti-shake driving force and can be used to drive the chip carrier 2 to move relative to the magnet support 1.

[0044] Generally, the driving magnet 31 is fixedly mounted on the magnet bracket 1 and connected to the outer shell of the camera module, and is in a stationary state; the driving coil 32 is mounted on the chip carrier 2 and can move relative to the driving magnet 31 when energized.

[0045] The rolling support assembly 4 is connected between the magnet bracket 1 and the chip carrier 2. It is used to roll or slide the chip carrier 2 into contact with the magnet bracket 1 and support the chip carrier 2, so that the distance between the magnet bracket 1 and the chip carrier 2 is kept stable, thus maintaining the spatial orientation stability of the image sensor chip. That is, during the movement of the chip carrier 2, with the magnet bracket 1 as the reference, the distance from each area of ​​the chip carrier 2 to the magnet bracket 1 is kept stable, and it can only move in translation relative to the magnet bracket 1. This maintains the spatial orientation stability of the chip carrier 2 during the movement, reduces the risk of the chip carrier 2 and the image sensor chip on it tilting to one side, and ensures the quality of the image captured by the image stabilization system.

[0046] The image stabilization mechanism provided in this application uses a magnet bracket as the basis for image stabilization. The chip carrier is stably connected to the magnet bracket by the rolling support component 4 and a stable distance is maintained. Thus, when the image sensor chip is installed on the chip carrier, it can move within a plane at a set distance from the magnet bracket and strictly limit the posture changes of the image sensor chip, such as tilting or sinking on one side, to ensure shooting quality.

[0047] See Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the rolling support component 4 can pull the chip carrier 2 tightly onto the magnet bracket 1, thereby restricting the chip carrier 2 from approaching or moving away from the magnet bracket 1, maintaining only the distance between it and the magnet bracket 1, and rolling to support the chip carrier 2, thus achieving smooth translation of the chip carrier 2.

[0048] The rolling support assembly 4 may include an attractive magnet 41, an attractive carrier plate 42, and a plurality of balls 43; wherein the attractive magnet 41 and the attractive carrier plate 42 may be configured as functional components capable of attracting each other, and are respectively mounted on the magnet support 1 and the chip carrier 2, thereby maintaining a stable attractive force between the magnet support 1 and the chip carrier 2; the plurality of balls 43 can roll against the attractive carrier plate 42 of the magnet support 2, thereby clamping the plurality of balls 43 between the magnet support 1 and the chip carrier 2, maintaining the reliability of the rolling support.

[0049] It is worth noting that there are multiple balls 43, which can form multiple rolling support points between the magnet support 1 and the chip carrier 2, forming a stable surface support state, so as to ensure that the distance between the magnet support 1 and the chip carrier 2 remains consistent. Thus, when the chip carrier 2 moves, it can only move within a set plane, limiting the spatial posture changes of the chip carrier 2 such as tilting or sinking on one side.

[0050] Generally, the multiple balls 43 are arranged coplanarly and dispersedly to form multiple independent support points of equal height, and are avoided to be arranged along a straight line, thereby forming a stable support surface and holding the chip carrier 2 within the magnet bracket 1 at a set distance.

[0051] See Figure 4 and Figure 5 In some embodiments, in order to further improve the support stability of the plurality of balls 43, a rolling groove 431 can be formed on the magnet bracket 1 to accommodate and constrain the balls 43, prevent the balls 43 from moving out of position, and thus maintain the stability of the rolling support height of the chip carrier 2.

[0052] In some embodiments, the number of the rolling grooves 431 is the same as the number of the plurality of balls 43, and the balls 43 are arranged independently and dispersedly, so that each ball 43 can be independently and rotatably disposed in one of the rolling grooves 431, thereby keeping the distance between two adjacent balls 43 stable, thus maintaining the support stability of the chip carrier 2 and avoiding the risk of the chip carrier 2 tilting upwards due to the positions of the balls 43 being too close.

[0053] Generally, the multiple balls 43 can be distributed in the edge area of ​​the chip carrier 2 to enhance the ability to limit the chip carrier 2 from tilting up on one side.

[0054] In some embodiments, in order to further enhance the stability of the distance between the chip carrier 2 and the magnet support 1, a magnetic attraction element, such as a magnetic metal sheet, can be added to the chip carrier 2 corresponding to the driving magnet 31 to form a stable magnetic attraction force and further press the ball 43, thereby reducing the risk of local uplift of the chip carrier 2 caused by the chip carrier 2 and the magnet support 1 being relatively far apart.

[0055] In some embodiments, the opening of the rolling groove 431 can be configured as a spherical arc surface 431a that matches the ball 43. The ball 43 rolls against the spherical arc surface 431a so that the ball 43 rolls in place within the rolling groove 431, thereby maintaining the stability of the plurality of balls 43 on the magnet support 1 and maintaining the stability of the rolling support range of the chip carrier 2, thus avoiding the deterioration of the support stability and reliability of the plurality of balls 43 due to the reduction of the support range.

[0056] In some embodiments, the ball bearings 43 may be configured as three, which can form a stable three-point rolling support.

[0057] In some embodiments, in order to reduce interference with the surrounding structure, the number of the attracting magnets 41 and the attracting carriers 42 may be the same as the number of the balls 43, that is, each attracting magnet 41 and attracting carrier 42 corresponds to one ball 43.

[0058] Correspondingly, the ball 43 is always located within the relative range of the attracting magnet 41 and the attracting carrier 42. Therefore, the size and specifications of the attracting magnet 41 and the attracting carrier 42 can be set according to the moving stroke of the chip carrier 2.

[0059] In some embodiments, the positions of the three balls 43 can be planned so that the line connecting the three balls 43 forms an isosceles triangle, thereby optimizing the uniformity of the three-point support for the chip carrier 2 and maintaining a stable support state for the chip carrier 2 during its movement.

[0060] Generally, the line connecting the three balls 43 can be further set as an equilateral triangle, that is, the distance between any two adjacent balls 43 is equal, which further enhances the support stability.

[0061] join Figure 3 and Figure 4 In some embodiments, considering that image sensor chips are mostly rectangular, in order to balance the anti-shake drive structure and the space utilization of the image sensor chip, the chip carrier 2 can also be set as rectangular.

[0062] Therefore, the three balls 43 can be divided into two groups, respectively disposed on the parallel first rectangular side 21 and the second rectangular side 22 of the chip carrier 2; wherein, one ball 43 abuts against the middle of the first rectangular side 21, and the other two balls 43 abut against the two ends of the second rectangular side 22, thereby reducing the risk of interference to other structures to a certain extent.

[0063] In some embodiments, the driving magnet 31 and the driving coil 32 can be configured as four, corresponding to the four rectangular sides of the chip carrier 2. The force on the four driving coils 32 in the energized state can be configured to extend along the rectangular side where they are located. Thus, when the rectangular image sensing chip is mounted on the chip carrier 2, the anti-shake movement direction can be planned and configured with the rectangular side of the chip carrier 2 as a reference.

[0064] To accommodate the ball bearing 43 located in the middle of the first rectangular side 21, the drive coil 32 can be configured as two short coils, arranged on both sides of the ball bearing 43.

[0065] In some embodiments, in order to simplify the layout complexity on the magnet support 1, the attracting magnet 41 can be disposed on the side surface of the magnet support 1 away from the ball 43, and the driving magnet 31 and the rolling groove 431 can be disposed on the side surface of the magnet support 1 close to the ball 43.

[0066] In some embodiments, the rolling support assembly can be configured as a matching slide rail and a slider, which are slidably connected and respectively connected to the chip carrier 2 and the magnet support 1; that is, by utilizing the stable sliding of the slider on the slide rail, the distance between the chip carrier 2 and the magnet support 1 is kept stable.

[0067] See Figure 1 and Figure 2 In some embodiments, in order to reduce the installation height, a fixing groove 11 can be formed on the magnet bracket 1 to accommodate and fix the driving magnet 31.

[0068] In some embodiments, the magnet support 1 can be configured as a box-shaped housing, and the chip carrier 2 can be suspended from the lower inner side of the magnet support 1 by the rolling support assembly 4, thereby simplifying the support structure of the chip carrier 2, reducing the complexity of the overall spatial structure, and reducing the risk of interference.

[0069] In some embodiments, the magnet support 1 may also be configured as a base-shaped support, which is supported and tightened on the magnet support 1 by the rolling support assembly 4.

[0070] In some embodiments, a camera module including the above-described image stabilization mechanism is also provided. The camera module may further include an image sensor chip 5 and a module circuit board 6.

[0071] The image sensing chip 5 is disposed on the chip carrier 2, and the module circuit board 6 is electrically connected to the image sensing chip 5.

[0072] In some embodiments, the chip carrier 2 may be configured as a printed circuit board, and the module circuit board 6 and the image sensing chip 5 are respectively disposed on both sides of the chip carrier 2 and electrically connected through the pre-embedded circuit of the printed circuit board.

[0073] In some embodiments, the module circuit board 6 adopts a spring wire plate, which can adapt to the movement of the chip carrier 2 by the deformation of the spring wire, thereby reducing the impact on the posture of the movement of the chip carrier 2.

[0074] In some embodiments, in order to reduce the influence of interfering light, a filter 7 can be provided at the photosensitive surface of the image sensor chip 5 to filter the interfering light projected onto the image sensor chip 5.

[0075] Generally, the filter 7 can be fixed on the magnet bracket 1 by the filter bracket 71.

[0076] In some embodiments, the camera module is further configured with a base 8 for matching and connecting the magnet bracket 1 to form a stable and sealed protective housing structure that protects the functional components of the camera module.

[0077] The embodiments of this application have at least the following beneficial effects:

[0079] Furthermore, the rolling support assembly can be configured with a cooperating attracting magnet, a ball, and an attracting carrier. The attracting magnet and the attracting carrier are respectively disposed on the magnet support and the chip carrier, and the ball is clamped between the attracting magnet and the attracting carrier. The magnetic attraction between the attracting magnet and the attracting carrier can be used to stably clamp the ball, so as to ensure the stability of the distance between the magnet support and the chip carrier in the rolling support state, thereby limiting the upward tilting.

[0080] Furthermore, the attracting magnet, ball bearing, and attracting carrier are set up as three sets to achieve a three-point rolling support. This utilizes the principle of fixing a plane with three points to ensure the stability of the chip carrier's position and orientation relative to the magnet support.
