[0002] The periscope camera module changes the optical path through a reflector, and a lens assembly and an image sensor are arranged sequentially along the light-emitting side optical axis of the reflector. The lens assembly is used to converge light and form an image, and the image sensor converts the light signal into an electrical signal to record the image.

[0003] Periscope cameras compensate for the effects of camera shake on image quality by rotating a mirror relative to the lens assembly. However, when the camera module is shaken or jolted by external forces, the image stabilization module may cause the mirror to produce undesirable pitch movements, affecting image quality.

[0008] Optionally, the first support portion is hemispherical; or, the first support portion is cylindrical.

Detailed Implementation

[0019] 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 some embodiments of this application, and not all 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 utility model.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0021] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0022] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0023] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0024] Figure 1 This is a schematic diagram of a periscope camera module 200 in related technologies. Figure 2 for Figure 1 A cross-sectional view of the periscope camera module 200 along the AA direction. (See image.) Figure 1 and Figure 2As shown, in the related technology, a periscope camera module 200 has a base 4 with a reflective component 1 connected to a stabilization bracket 3, and along the light-emitting side of the reflective component 1, the base 4 is also provided with a lens assembly 2 and an image sensor 7 in sequence.

[0025] The base 4 and the image stabilization bracket 3 are each equipped with magnetic components on the portion perpendicular to the optical axis of the light-emitting side, and the base 4 and the image stabilization bracket 3 are magnetically connected through their respective magnetic components. Three ball bearings are installed between the base 4 and the image stabilization bracket 3. Figure 3 and Figure 4 These are schematic diagrams of the base 4 and the image stabilization bracket 3. Three grooves are provided on the surfaces of the base 4 and the image stabilization bracket 3, respectively, to accommodate ball bearings. Figure 3 and Figure 4 The upper groove is a positioning ball receiving groove 51 for accommodating the positioning ball 5. The size of the groove is similar to that of the positioning ball 5, so that the positioning ball 5 can only roll in the groove and its position cannot move relative to the groove. The two grooves below are support ball receiving grooves 52 for accommodating the support ball. The opening size of the groove is larger than the cross-section of the ball, so that the support ball can move in the groove.

[0026] When camera module shake is detected during shooting, the image stabilization bracket 3 can be driven to rotate relative to the base 4 around the diameter direction of the supporting positioning ball 5, which is parallel to the light-emitting side optical axis. This counteracts the shake on the plane perpendicular to the light-emitting side optical axis. During the rotation of the image stabilization bracket 3 relative to the base 4, the supporting ball rolls within the groove while maintaining a fixed distance between the two opposing planes of the image stabilization bracket 3 and the base 4, ensuring that the two opposing planes remain parallel.

[0027] However, due to the limited precision of camera module components, for example, the two opposing surfaces of the image stabilization bracket 3 or base 4 may have uneven surface flatness. The support ball, due to external force causing shaking or vibration, rolls within the groove, changing its position. Before and after the change in the support ball's position, the surface flatness at the contact point between the image stabilization bracket 3 or base 4 and the support ball may differ. This causes a change in the distance between the two opposing planes at the contact point, causing the image stabilization bracket 3 to tilt the reflector component 1 relative to the base 4 at a certain angle, affecting image quality. Because the position of the support ball within the groove is uncontrollable, even if the rotation angle of the image stabilization bracket 3 relative to the base 4 can be controlled and adjusted, it is difficult to ensure that the distance between the image stabilization bracket 3 and the base 4 remains constant, preventing the image stabilization bracket 3 from experiencing tilting motion.

[0028] In this application, by limiting the position of the support member between the image stabilization bracket and the base to be relatively fixed relative to one of the image stabilization bracket and the base, and relatively movable relative to the other, the support member cannot be moved arbitrarily and change the distance between the image stabilization bracket and the base. Thus, when the relative rotation angle between the image stabilization bracket and the base is controllably adjusted, it can be ensured that the distance between the image stabilization bracket and the base is always fixed at the position of the support member, and the image stabilization bracket will not produce pitch motion.

[0029] This application discloses a stabilization module 100. Figure 5 This is a schematic diagram of the image stabilization module 100 according to an embodiment of this application. Figure 6 For the image stabilization module 100 edge Figure 5 Cross-sectional view along the BB direction. Figure 7 For the image stabilization module 100 edge Figure 5 A cross-sectional view along the CC direction. (e.g.) Figures 5 to 7 As shown, the image stabilization module 100 may include a reflective component 1, an image stabilization bracket 3, a base 4, a positioning ball bearing 5, and a support component 6.

[0030] The reflecting component 1 is used to reflect light incident along the first optical axis OA1 to exit along the second optical axis OA2. The reflecting component 1 may include a mirror support 11 and a mirror 12. The mirror support 11 is used to support the mirror 12 and drive the mirror 12 to rotate or pitch.

[0031] The image stabilization bracket 3 can be connected to the reflector assembly 1, so that when the reflector assembly 1 is driven by an external force in the vertical direction, it can pitch relative to the image stabilization bracket 3. Furthermore, when the image stabilization bracket 3 is driven by an external force to rotate in a plane perpendicular to the second optical axis OA2, it can drive the reflector assembly 1 to rotate in the same plane, thereby realizing the rotation of the reflector 12 around the second optical axis OA2. The image stabilization bracket 3 has a mounting surface 31. A first mounting groove is formed on the mounting surface 31.

[0032] The reflector assembly 1 and the image stabilization bracket 3 can be disposed on the base 4. The base 4 can have a sidewall 40 facing the mounting surface 31. The image stabilization bracket 3 can be movably connected to the sidewall 40 of the base 4, for example, by magnetic connection via magnetic elements (not shown) respectively disposed on the sidewall 40 and the reflector assembly 1 and / or the image stabilization bracket 3. The reflector assembly 1 and the image stabilization bracket 3 are interconnected, and the reflector assembly 1 can also be movably connected to the sidewall 40 of the base 4 in a similar manner. The sidewall 40 has a second mounting groove corresponding to the position of the first mounting groove, and the first mounting groove and the second mounting groove together form a limiting cavity 50.

[0033] The positioning ball 5 can be configured to roll within the limiting cavity 50, allowing the image stabilization bracket 3 to rotate relative to the base 4 about the diameter of the positioning ball 5, which is parallel to the second optical axis OA2. The positioning ball 5 is confined within the limiting cavity 50 and its position remains unchanged.

[0034] The support member 6 is fixed to one of the mounting surface 31 and the side wall 40, and the support member 6 abuts against the other of the mounting surface 31 and the side wall 40 and can move relative to each other, so as to maintain the distance between the mounting surface 31 and the side wall 40 when the anti-shake bracket 3 rotates relative to the base 4.

[0035] like Figure 7 As shown, one end of the support member 6 is fixed to the side wall 40 of the base 4, and the other end abuts against the mounting surface 31 of the anti-shake bracket 3. When the anti-shake bracket 3 rotates relative to the base 4 around the rotation axis, the support member 6 will move relative to the anti-shake bracket 3 because the support member 6 is fixed to the base 4.

[0036] The support member 6, positioned between the mounting surface 31 and the side wall 40, ensures that the distance between the mounting surface 31 and the side wall 40 remains fixed when the anti-shake bracket 3 rotates relative to the base 4. This guarantees that when the anti-shake bracket 3 rotates around the rotation axis, the reflector component 1 does not experience pitch movement, and the direction of the second optical axis OA2 does not change. Specifically, the length of the support member 6 can be set to match the distance between the mounting surface 31 and the side wall 40, ensuring that the mounting surface 31 and the side wall 40 remain parallel under the combined support of the positioning ball 5 and the support member 6, and that both the mounting surface 31 and the side wall 40 are perpendicular to the direction of the second optical axis OA2.

[0037] In the embodiments of this application, the example is that the position of the support member 6 is fixed relative to the base 4 and moves relative to the anti-shake bracket 3 when the anti-shake bracket 3 rotates relative to the base 4. In other embodiments, the support member 6 may also maintain a fixed position relative to the anti-shake bracket 3 and move relative to the base 4 when the anti-shake bracket 3 rotates relative to the base 4.

[0038] According to the image stabilization module of this application embodiment, a support member is provided between the mounting surface of the image stabilization bracket and the side wall of the base, supporting the bracket between the mounting surface and the side wall. The position of the support member is fixed relative to either the image stabilization bracket or the side wall of the base, thereby maintaining a fixed distance between the mounting surface and the side wall. Therefore, when the image stabilization bracket rotates relative to the side wall of the base about a diameter parallel to the second optical axis OA2 of the supporting ball, with the rotation angle controllable, it can ensure that the reflective component connected to the image stabilization bracket does not experience pitch movement, and the direction of the second optical axis OA2 remains unchanged.

[0039] The technical solutions of this application will be described in detail below with reference to specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0040] To ensure that one end of the support member 6 is fixed relative to the base 4 or the anti-shake bracket 3, the mounting surface 31 or side wall 40 of the fixed support member 6 can be provided with a first groove 311. The first groove 311 can be various shapes such as a V-shaped groove, a polygonal groove, or an arc-shaped groove. The support member 6 is disposed in the first groove 311. The first groove 311 is configured to abut against the support member 6 in at least two different directions, so that the positions of the support member 6 and the first groove 311 are relatively fixed.

[0041] One end of the support abuts against the base or anti-shake bracket, and the other end abuts against the first groove in at least two different directions. By contacting and providing support in three non-parallel directions, the support can be fixed in a fixed position, ensuring that the support and the base or anti-shake bracket with the first groove remain in a fixed relative position. At the same time, the first groove provides positioning for assembly, facilitating quick and accurate installation of the support.

[0042] Optionally, the support member 6 can be spherical. The first groove 311 has multiple interconnected groove walls that form an angle with each other. The first groove 311 can be a pyramidal groove or have a bottom wall at the bottom of the groove that is parallel to the mounting surface 31 or the side wall 40. Each groove wall of the first groove 311 abuts against the spherical support member 6.

[0043] When the spherical support moves relative to the mounting surface and the sidewall, it can reduce friction with the mounting surface or sidewall facing the first groove through rolling. In addition, the spherical support makes point contact with each groove wall of the first groove, and because the spherical support can rotate, it can convert some of the sliding friction into rolling friction, resulting in low overall movement resistance and uniform wear of the spherical support.

[0044] In order to reduce the wear caused by the friction between the support member 6 and the groove wall of the first groove 311, the support member 6 can also be fixedly installed in the first groove 311, so as not to move relative to the base 4 or the anti-shake bracket 3 provided with the first groove 311.

[0045] Optionally, the support member 6 may include a mounting base 61 and a first support portion 62 connected to each other. The mounting base 61 may be of various shapes, such as cylindrical or square, and its shape matches the shape of the first groove 311, allowing the mounting base 61 to be fitted into the first groove 311, thereby ensuring a precise and stable connection between the mounting base 61 and the base 4 or anti-shake bracket 3 provided with the first groove 311. The junction of adjacent side walls of the square mounting base 61 may be rounded, and the junction of adjacent side walls of the first groove 311 may be correspondingly rounded, thereby increasing the contact surface between the mounting base 61 and the opposite side walls of the first groove 311 and dispersing stress. The first support portion 62 protrudes at least partially from the first groove 311, and the end of the first support portion 62 away from the mounting base 61 abuts against the other of the mounting surface 31 and side wall 40 that is not fixed to the support member 6. The first support portion 62 extends from the mounting base 61, and its end makes point contact or surface contact with the mounting surface 31 or side wall 40 facing the first groove 311, and provides support when there is relative movement with the side wall of the anti-shake bracket 3 or the base 4.

[0046] By setting the support component, which includes a mounting base and a first support part, and embedding the mounting base into the first groove, it is possible to ensure a precise and stable connection between the support component and the base or anti-shake bracket with the first groove, thus preventing relative movement between the support component and the first groove and avoiding wear on the support component. At the same time, it reduces the complexity of processing and assembly, and makes it easier to meet the precision requirements of each component compared to simultaneously ensuring the surface accuracy of the groove wall and the sphere surface.

[0047] To further ensure a stable connection between the support 6 and the base 4 or the anti-shake bracket 3 with the first groove 311, the first groove 311 and the mounting base 61 can be bonded together with glue or the like.

[0048] Because the distance between the mounting surface 31 and the side wall 40 is limited, only a smaller first support portion 62 can protrude from the mounting base 61, making the machining of the first support portion 62 more difficult. To facilitate the machining and manufacturing of the first support portion 62 or the support member 6, such as... Figure 7 As shown, the mounting surface 31 or sidewall 40 that abuts against the support member 6 may be provided with a second groove 411 at a position corresponding to the first groove 311, so that the end of the first support portion 62 away from the mounting base 61 abuts against the bottom wall of the second groove 411. This arrangement allows the first support portion 62 or the support member 6 to be designed with a larger size, facilitating the processing and manufacturing of the first support portion 62 or the support member 6.

[0049] Optionally, the first support portion 62 can be hemispherical. For example... Figure 8The diagram shows a support member 6 according to an embodiment of this application. The planar portion of the first support portion 62 is connected to the mounting base 61, and the spherical surface of the first support portion 62 abuts against either the mounting surface 31 or the side wall 40 where the support member 6 is not fixed. The radius of the hemispherical first support portion 62 can be set according to the depth of the first groove 311 and / or the second groove 411, the thickness of the mounting base 61, and the distance between the mounting surface 31 and the side wall 40. For example, the thickness of the mounting base 61 and the radius of the hemispherical first support portion 62 can be set to be the same as the radius of the positioning ball 5 to facilitate the processing and assembly of the various components.

[0050] The hemispherical first support can provide point contact with the mounting surface or sidewall facing the first groove, reducing friction between the support and the anti-shake bracket or base sidewall.

[0051] It is understood that the "hemispherical" shape described in this application is not limited to a standard hemisphere. Any part that is cut off from a sphere in accordance with the spirit of this utility model can be understood as falling within the scope of the "hemispherical" shape described in this application.

[0052] In other embodiments, the first support portion 62 can be cylindrical. For example... Figure 9 The diagram shown is a schematic representation of another support member 6 according to an embodiment of this application. The end face of the first support portion 62 abuts against one of the mounting surfaces 31 or side walls 40 where the support member 6 is not fixed. The junction between the side surface and the end face of the cylindrical first support portion 62 can be rounded to reduce the resistance to movement between the support portion 62 and the abutting mounting surface 31 or side wall 40 when they move relative to each other.

[0053] By setting the first support part in a cylindrical shape, it can provide relatively stable support to the mounting surface or sidewall facing the first groove. When the cylindrical first support part is subjected to pressure, the contact point with the mounting surface or sidewall is not prone to shaking or deformation; and when subjected to wear caused by friction, the wear on the end face of the first support part will not easily change the distance between the mounting surface and the sidewall, thereby preventing the reflective component from generating a pitch angle and changing the direction of the second optical axis OA2.

[0054] The first support part 62 or the support member 6 can be made of a self-lubricating material such as Teflon, thereby reducing the friction between the support member 6 and the mounting surface 31.

[0055] Optionally, to avoid creating grooves on the mounting surface 31 or sidewall 40, the support member 6 can also be fixedly connected to the surface of the mounting surface 31 or sidewall 40. Specifically, the support member 6 can be connected to the surface of the mounting surface 31 or sidewall 40 by means of adhesive bonding or other methods.

[0056] By fixing the support to the surface of the mounting surface or side wall, the grooves in the mounting surface or side wall are avoided, simplifying the processing and manufacturing process.

[0057] Optionally, the support member 6 may include a second support portion, which protrudes from either the mounting surface 31 or the side wall 40 that fixes the support member 6, and the second support portion may have a similar shape to the first support portion 62, being hemispherical or cylindrical.

[0058] The hemispherical second support provides point contact with the mounting surface and sidewall facing the first groove, reducing friction between the support and the anti-shake bracket or base sidewall. The cylindrical second support provides relatively stable support to the mounting surface or sidewall facing the first groove. When subjected to pressure, the cylindrical second support is less prone to shaking or deformation at the contact point with the mounting surface or sidewall; and when subjected to wear caused by friction, partial wear on the end face of the second support will not easily change the distance between the mounting surface and the sidewall, thereby preventing the reflective assembly 1 from generating a pitch angle and changing the direction of the second optical axis OA2.

[0059] Optionally, the support member 6 is integrally formed with the base 4 or the anti-shake bracket 3 that connects to the support member 6.

[0060] By integrally molding the support component with the base or anti-shake bracket connected to it, the connection between the support component and the base or anti-shake bracket is made more stable, preventing the support component from detaching from the base or anti-shake bracket. At the same time, it eliminates the need for assembling multiple parts, removing dimensional deviations caused by assembly and simplifying manufacturing costs.

[0061] Optionally, the image stabilization module includes at least two support members 6, with positioning balls 5 arranged in a triangle with the support members 6, and the triangle forming an obtuse angle at the positioning balls 5. Figure 10 The image shown is a front view of the anti-shake bracket 3, which is equipped with positioning ball 5 and support member 6. The line connecting the center of the positioning ball 5 and the center of the two support members 6 forms a triangle, and the angle A of the triangle located at the center of the positioning ball 5 is an obtuse angle.

[0062] Setting up at least two support members provides more stable support for the side walls of the image stabilization bracket and base. The positioning ball and the two support members are arranged in a triangle to support a stable plane. The obtuse angle at the positioning ball means that the distance between the two support members is relatively large, which can achieve a wider support base. This makes the support structure formed by the positioning ball and the support members stable and not easy to flip laterally. This ensures that the mounting surface or side wall that abuts the support members will not tilt, that is, the reflective component will not pitch, and the direction of the second optical axis OA2 will not change.

[0063] Optionally, the triangle can be an isosceles triangle. For example... Figure 10As shown, the positioning ball 5 is equidistant from the two support members 6. That is, the center of the positioning ball 5 is the vertex of an isosceles triangle, and the lines connecting the center of the positioning ball 5 and the centers of the two support members 6 respectively form two equal sides of the isosceles triangle.

[0064] The positioning balls and the support components are arranged in an isosceles triangle, meaning the support components are symmetrically set, which ensures balanced force distribution and a stable support structure formed by the positioning balls and the support components. At the same time, the symmetrical design makes the assembly of the support components easier.

[0065] This application also discloses a camera module. The camera module of this application can be applied to electronic devices such as mobile phones, cameras, or tablets, and is used to realize functions such as taking photos, videos, or recording videos. It includes: the image stabilization module, lens assembly, and image sensor described in the foregoing embodiments.

[0066] The lens assembly can be positioned on the light-emitting side of the reflective assembly to receive light from the reflective assembly and propagate the light along the second optical axis OA2. The lens assembly may include a set of lenses positioned along the direction of the second optical axis OA2. The lens assembly can be connected to the base via a lens bracket and moved relative to the base along the direction of the second optical axis OA2, thereby adjusting the distance between the lens assembly and the reflective assembly.

[0067] An image sensor is used to receive light from the lens assembly and form an image. The image sensor can be a charge-coupled device (CCD) sensor or a complementary metal-oxide-semiconductor (CMOS) sensor, etc., and converts the optical image captured by the lens assembly into electronic signals, enabling these signals to be processed, stored, and displayed. The image sensor is positioned along the second optical axis at the light exit point of the lens assembly 2 of the image stabilization module. Specifically, the image sensor can be fixedly positioned perpendicular to the second optical axis on the opposite side of the base relative to the side wall 40.

[0068] The camera module provided in the application embodiment has a support member between the mounting surface of the image stabilization bracket and the side wall of the base, which is fixed relative to either the image stabilization bracket or the side wall of the base, thereby maintaining a fixed distance between the mounting surface and the side wall. Therefore, when the image stabilization bracket rotates relative to the side wall of the base about a diameter parallel to the second optical axis OA2 of the supporting ball bearing, with a controllable rotation angle, it can ensure that the reflective component connected to the image stabilization bracket does not experience pitch movement, and the direction of the second optical axis OA2 remains unchanged.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
