Description

Technical Field

[0001] The present invention relates to the field of optical imaging, and particularly to a periscope camera module. Background Art

[0002] The periscope lens structure generally includes two parts, namely the lens part and the prism part. The prism part is arranged at the front end of the periscope part, and an imaging chip is arranged at the rear end of the lens part. Light is reflected by the prism part and enters the lens part.

[0003] The shooting function of the cameras of existing electronic devices is becoming more and more powerful. Conventional photographic lenses can only shoot images of close scenes (1 - 2 meters). If clear shooting is to be carried out for distant scenes (10 - 20 meters), the lens must have a telephoto or zoom function. However, such lenses often require a long stroke to achieve zoom, resulting in a relatively long total length of the lens, and the height of the lens exceeding the thickness of the electronic device, making it difficult to meet the requirements of the thin and light or thin design of mobile terminal devices. For this reason, a periscope design as shown in Figure 1 is usually adopted, that is, the optical path is designed to be horizontal, and a prism is added to rotate the optical path by 90 degrees. At this time, the prism bracket on the mechanism needs to make small-angle fine-tuning of θx and θy to perform OIS hand vibration compensation, so that the entire optical system lies flat to reduce the overall height, and cooperate with the focusing motor to complete focusing or zooming in the Z-axis direction.

[0004] Under the requirement of improving the image resolution, the size of the image sensor (CMOS Sensor) is increased, the size of the rotating prism is increased, and the weight also increases greatly, resulting in insufficient thrust of the rotating motor and the response speed being affected. In addition, both-axis rotation acts on the prism part, and the close distance between the driving devices of both-axis rotation will cause mutual interference of the sensors, reducing the sensing accuracy.

[0036] Embodiment:

[0037] As Figure 2 shown, the optical axis direction is parallel to the Z-axis direction. In one embodiment, the first axis A1 is parallel to the X-axis direction, and the second axis A2 is parallel to the Y-axis direction; in one embodiment, the first axis A1 can be parallel to the Y-axis direction, and the second axis A2 can be parallel to the X-axis direction;

[0038] In the following text, mainly the structure in which the first axis A1 is parallel to the X-axis direction and the second axis A2 is parallel to the Y-axis direction will be described. The optical axis direction can also be referred to as the Z direction, the first axis A1 direction can also be referred to as the X direction, and the second axis A2 direction can also be referred to as the Y direction;

[0039] A periscope camera module includes a housing 100, a reflection module 200, and a lens module; the housing 100 has an internal space that can protect and support the optical elements accommodated therein; usually, the housing 100 is similar to an uncovered box body, and there is a through hole at the tail. After the light passes through the lens module 500, it will pass through the through hole and then enter the imaging module (not shown in the figure) located at the tail of the through hole; usually, a top cover 110 is also provided on the top of the housing 100, and the top cover 110 partially closes the housing 100; a light inlet hole 111 is provided on the housing 100 for light to enter the reflection module 200. Therefore, the light inlet hole 111 is disposed opposite to the reflection module 200;

[0040] In one embodiment, the reflection module 200 is disposed in the internal space of the housing 100. The reflection module 200 can change the direction of light to the direction of the optical axis, and the direction of the optical axis is parallel to the Z-axis direction. The reflection module 200 is configured to be rotatable relative to the housing 100 about a first axis A1, that is, rotatable about the X-axis direction. By configuring the reflection module 200 to only rotate about the first axis A1, the structure of the reflection module 200 can be effectively simplified. It can be understood that in the prior art, the reflection module 200 usually needs to be configured to rotate in two mutually perpendicular directions, so at least two bracket structures are required, which places high requirements on the assembly accuracy and the thrust of the actuating component. In the present invention, only one rotation direction is provided, so that the reflection module 200 only needs one bracket to achieve the expected motion effect;

[0041] As Figure 3 shown, in one embodiment, the lens module 500 is disposed in the optical axis direction and includes at least two lens groups. One of the lens groups is configured to be rotatable relative to the housing 100 about a second axis A2. One of the lens groups is configured to be movable along the optical axis direction. In one embodiment, the lens module 500 includes a first lens group 300 and a second lens group 400. The first lens group 300 is configured to be rotatable about the second axis A2, and the second lens group 400 is configured to be movable along the optical axis direction. The first lens group 300 is disposed close to the reflection module 200. The rotation of the reflection module 200 about the first axis A1 and the rotation of the first lens group 300 about the second axis A2 together achieve the OIS optical anti-shake of the imaging module. In one embodiment, the lens module 500 can also be configured with more lens groups. One of the lens groups closest to the reflection module 200 is configured to be rotatable relative to the housing 100 about the second axis A2, and one of the lens groups farthest from the reflection module is configured to be movable along the optical axis direction. It can be understood that in the prior art, the lens module 500 usually includes multiple lenses. Therefore, the lens module 500 can be split into multiple lens groups. Taking a common lens module 500 with 6 lenses as an example, 6P can be split into combinations such as 1P + 5P, 2P + 4P, 3P + 3P, 4P + 2P, 5P + 1P, etc. Among them, 1P + 5P means that the first lens group 300 includes one lens, and the second lens group 400 includes 5 lenses. The same applies to the other combinations;

[0042] Although the first lens group 300 is disposed adjacent to the reflection module 200, since the reflection module 200 and the first lens group 300 itself have a certain volume, the distance between the first actuating component 230 for driving the movement of the reflection module 200 and the second actuating component 310 for driving the movement of the first lens group 300 can be made as large as possible, thereby effectively avoiding the problem of sensor interference between the first actuating component 230 and the second actuating component 310 and effectively improving the accuracy of movement; the rotational movements of the first lens group 300 and the reflection module 200 are relatively independent, and there will be no direct mutual interference in accuracy between the two, thus ensuring high-precision control of their respective rotations.

[0043] In an embodiment, the reflection module 200 includes a reflection component 210 for changing the propagation direction of light and a movable carrier 220 for carrying the reflection component 210; the reflection component 210 is usually a prism; a first actuating component 230 for driving the rotation of the reflection module 200 is provided in the housing 100; the first actuating component 230 includes a first magnet 231 and a first coil 232 which are oppositely arranged; the first magnet 231 is disposed in a first magnet receiving groove 223 on the movable carrier 220; the first coil 232 is disposed on the housing 100; as Figure 2 shown, the first coil 232 is disposed on the first side surface 108 of the housing 100, and a second side surface 109 is connected to each of the two sides of the first side surface 108, and the two second side surfaces 109 are oppositely arranged; in an embodiment, the first side surface 108 may be hollowed out to accommodate the first coil 232 to reduce the occupation of the internal space; the first magnet 231 is also embedded in the movable carrier 220 to reduce the occupation of space;

[0044] In one embodiment, the reflection module 200 is rotatably connected to the housing 100 through a first pivot member 240; the first pivot member 240 is disposed between the reflection module 200 and the housing 100 to provide the first axis A1; a first accommodation groove 224 cooperating with the first pivot member 240 is provided on the reflection module 200; a second accommodation groove 101, which is disposed opposite to the first accommodation groove 224 and is used for cooperating with the first pivot member 240, is provided on the housing 100; in one embodiment, the first pivot member 240 is a spherical member; in one embodiment, the first pivot member 240 is a cylindrical member; in one embodiment, the first pivot member 240 is disposed in the first accommodation groove 224 and forms an integral structure with the movable carrier 220. It can be understood that the first pivot member 240 is a spherical member or a cylindrical member protruding in the first accommodation groove 224; in one embodiment, the first pivot member 240 is disposed in the second accommodation groove 101 and forms an integral structure with the housing 100. It can be understood that the first pivot member 240 is a spherical member or a cylindrical member protruding in the second accommodation groove 101;

[0045] In one embodiment, when the first pivot member 240 is a spherical member, the first accommodation groove 224 and / or the second accommodation groove 101 can be one of a tapered groove, a multi-faceted groove, a V-shaped groove, and a square groove; as Figure 5 shown, in one embodiment, the first accommodation groove 224 is a multi-faceted groove, specifically a three-sided groove. Refer to Figure 5 . The shape of the three-sided groove formed by the first accommodation groove 224 can be the shape formed by three adjacent sides of a regular hexagon. When the first accommodation groove 224 cooperates with the spherical member, it is in contact with the spherical member at three points, which can effectively reduce the contact area and improve the smoothness of the movement of the reflection module 200; in one embodiment, when the first pivot member 240 is a cylindrical member, the structures of the multi-faceted groove and the V-shaped groove are also applicable; in one embodiment, the first pivot member 240 can also be a cylindrical shaft penetrating the reflection module 200;

[0046] As Figure 2 and Figure 5 shown, in one embodiment, the bottom of the reflection module 200 is limitedly connected to a bottom magnet 250 through a bottom magnet accommodation groove 221; a first magnetic conductive sheet 105, which is disposed opposite to the bottom magnet 250, is fixedly provided in the housing 100; the bottom magnet 250 and the first magnetic conductive sheet 105 are spaced apart; when the bottom magnet 250 cooperates with the first magnetic conductive sheet 105, a magnetic attraction force can be generated. Relying on the magnetic attraction force, the reflection module 200 can be effectively adsorbed on the housing 100. It can also be understood that relying on the magnetic attraction force, the reflection module 200 can effectively abut against the first pivot member 240, which can avoid the displacement of the reflection module 200 caused by some vibrations and effectively ensure the stability of the relative position of the reflection module 200;

[0047] The side of the reflection module 200 is limitedly connected to the side magnetic attraction magnet 260 through the side magnetic attraction magnet accommodation groove 222; a second magnetic conductive sheet 106 is fixedly arranged in the housing 100 opposite to the side magnetic attraction magnet 260; the side magnetic attraction magnet 260 and the second magnetic conductive sheet 106 are arranged at intervals; the side magnetic attraction magnet 260 can cooperate with the bottom magnetic attraction magnet 250 to further ensure the stability of the relative position of the reflection module 200 inside the housing 100;

[0048] In an embodiment, the first lens group 300 is rotatably connected to the housing 100 through a second fulcrum member 320; the second fulcrum member 320 includes a main member 321 providing the second axis A2 and a plurality of auxiliary members 322 arranged away from the main member 321; in an embodiment, two auxiliary members 322 are arranged; in an embodiment, both the main member 321 and the auxiliary members 322 are spherical members; the main member 321 is arranged between a third accommodation groove 301 formed in the first lens group 300 and a fourth accommodation groove 102 formed in the housing 100; the third accommodation groove 301 and the fourth accommodation groove 102 are arranged opposite to each other; the main member 321 rotates in place in a sandwiched state between the third accommodation groove 301 and the fourth accommodation groove 102; both the first lens group 300 and the housing 100 partially accommodate the auxiliary members 322; a first guiding groove 302 cooperating with the auxiliary members 322 is arranged on the first lens group 300 along the circumferential direction of the second axis A2; a second guiding groove 103 cooperating with the auxiliary members 322 is arranged on the housing 100 along the axial direction of the second axis A2. The auxiliary members 322 can support the first lens group 300 to prevent the rotation axis of the first lens group 300 from tilting;

[0049] As Figure 2 With Figure 6 shown, the third accommodation groove 301 and the fourth accommodation groove 102 are multi-faceted grooves, specifically octagonal grooves; in an embodiment, the third accommodation groove 301 and the fourth accommodation groove 102 are one of a conical groove, a V-shaped groove, and a square groove, so that the main member 321 can only rotate in place, and the in-place rotation can be understood as the spherical member rotating around its center; the main member 321 can perform a rotational movement rather than a translational movement. When the first lens group 300 rotates around the second axis A2, the main member 321 can remain in a relatively fixed position relative to the first lens group 300 and the housing 100, that is to say, the main member 321 can provide the rotation axis (i.e., the second axis A2) of the first lens group 300; in an embodiment, the multi-faceted groove can include three or more inclined surfaces, and the main member 321 can achieve a cooperation mode of one point contacting one inclined surface. For example, the third accommodation groove 301 and the fourth accommodation groove 102 can be in the shape of a triangular pyramid with its head cut off;

[0050] In one embodiment, the first guiding groove 302 and the second guiding groove 103 may extend in an arc shape around the second axis A2; for example, the center of curvature of the guiding groove is located on the second axis A2. When the guiding groove has a curved shape, the first lens group 300 can rotate more stably;

[0051] In one embodiment, the main member 321 is a spherical member, and the main member 321 is integrally formed with the first lens group 300 or integrally formed with the housing 100; in one embodiment, the auxiliary member 322 is a spherical member, and the auxiliary member 322 is integrally formed with the first lens group 300 or integrally formed with the housing 100; the spherical member may be a hemispherical member or a member similar to a hemispherical member;

[0052] In one embodiment, a plurality of second actuating components 310 for driving the first lens group 300 to rotate are provided between the first lens group 300 and the housing 100; the second actuating components 310 include a second magnet 311 and a second coil 312 which are oppositely arranged; the second magnet 311 is arranged in a second magnet accommodating groove 303 on the first lens group 300; the second coil 312 is arranged on the housing 100; in one embodiment, two second actuating components 310 which are oppositely arranged are included, and the second coil 312 is arranged on the second side surface 109; in one embodiment, one second actuating component 310 is provided to reduce magnetic leakage on the other side;

[0053] In one embodiment, the second lens group 400 is movably connected to the housing 100 through a third fulcrum member 420; the third fulcrum member 420 is arranged between a fifth accommodating groove 401 formed in the second lens group 400 and a sixth accommodating groove 104 formed in the housing 100; the fifth accommodating groove 401 and the sixth accommodating groove 104 are oppositely arranged; both the fifth accommodating groove 401 and the sixth accommodating groove 104 extend along the optical axis direction; the bottom of the second lens group 400 is limitedly connected to a reinforcement magnet 430 through a reinforcement magnet accommodating groove 403; a third magnetic conductive sheet 107 which is oppositely arranged with respect to the reinforcement magnet 430 is fixedly arranged in the housing 100; the reinforcement magnet 430 and the third magnetic conductive sheet 107 are arranged at intervals; in one embodiment, the third fulcrum member 420 may be a cylindrical shaft; in one embodiment, the third fulcrum member 420 may be a group of balls;

[0054] In one embodiment, a third actuation component 410 for driving the movement of the second lens group 400 is provided between the second lens group 400 and the housing 100; the third actuation component 410 includes a third magnet 411 and a third coil 412 which are oppositely arranged; the third magnet 411 is arranged in a third magnet accommodation groove 402 on the second lens group 400; the third coil 412 is arranged on the housing 100; in one embodiment, the third coil 412 is arranged on the second side surface 109, and the second coil 312 is arranged on another second side surface 109, so as to further increase the distance between the second actuation component 310 and the third actuation component 410, reduce crosstalk, and improve the movement precision of each.

[0055] In one embodiment, the housing 100 includes an FPC board 120 fixedly connected thereto; the FPC board 120 is electrically connected to the coil; it can be understood that the first coil 232, the second coil 312, and the third coil 412 are all electrically connected to the FPC board 120.

[0056] In one embodiment, the first axis A1 can be parallel to the Y-axis direction, and the second axis A2 can be parallel to the X-axis direction; no corresponding view is provided in this embodiment, but in combination with the foregoing description, it can be understood that by simply replacing the first fulcrum member 240 of the reflection module with the second fulcrum member 320, the reflection module 200 can be rotated around the Y-axis.
