Description

Technical Field

[0001] This disclosure relates to the field of optical imaging technology, and in particular to a camera module and electronic device. Background Technology

[0002] In mobile phones and other electronic devices, periscope lenses are mostly used to meet consumers' needs for long-distance shooting.

[0003] A periscope lens comprises a housing, a prism, a lens assembly, and an image sensor. The prism, lens assembly, and image sensor are all housed within the housing, which has a light-transmitting area. The object-side surface of the prism is positioned opposite the light-transmitting area, and the image sensor is positioned opposite the image-side surface of the prism. The lens assembly is positioned between the image-side surface and the image sensor. Light passes through the light-transmitting area, is refracted by the prism, and then transmitted through the lens assembly to reach the image sensor.

[0004] However, in the above structure, the lens group is positioned between the prism and the image sensor. The size of the lens group is limited by the thickness of the electronic device, which results in a smaller amount of light entering the camera module and a longer exposure time required for shooting, leading to poor image stabilization of the camera module. Utility Model Content

[0005] This disclosure provides a camera module and an electronic device that can solve the technical problems existing in related technologies. The technical solutions of the camera module and electronic device are as follows:

[0006] On one hand, this disclosure provides a camera module, which includes a housing assembly, a prism, a first lens group, a second lens group, an image sensor, and a first driving assembly;

[0007] The housing assembly has a light-transmitting area;

[0008] The prism has a first light-incident area and a first light-outcident area, and the first light-incident area is arranged opposite to the light-transmitting area.

[0009] The first lens group and the second lens group are distributed at intervals along the light incident direction of the prism and are respectively arranged opposite to the first light incident area;

[0010] The image sensor is arranged opposite to the first light-emitting area;

[0011] The first driving component is used to drive the first lens group and the second lens group to move in a direction perpendicular to the axis of the light-transmitting area.

[0012] Using the technical solution provided in this disclosure, the extension direction of the first light-incident area of ​​the prism is usually the length and width direction of the electronic device. The first lens group and the second lens group are respectively arranged opposite to the first light-incident area, so that both the first lens group and the second lens group extend in the length and width direction of the electronic device. They are not limited by the thickness of the electronic device. Therefore, the size of the first lens group and the second lens group can be set to be larger, thereby increasing the overall light intake of the camera module, and thus shortening the exposure time required when the camera module takes pictures, thereby improving the image stabilization capability of the camera module.

[0013] In some possible implementations, the first lens group is located within the light-transmitting area.

[0014] This avoids the edges of the light-transmitting area from blocking the first lens group, further increasing the amount of light entering the camera module and thus further improving the image stabilization performance of the camera module.

[0015] In some possible implementations, the first light-incident region and the first light-exit region face the same direction.

[0016] In this way, the first light-emitting area also extends in the length and width direction of the electronic device. Since the image sensor is arranged opposite to the first light-emitting area, the image sensor can extend in the length and width direction of the electronic device. The size of the image sensor is not limited by the thickness of the electronic device, and its size can be set to be larger, thereby improving the imaging quality of the camera module.

[0017] In some possible implementations, the prism has a light-transmitting surface, a first reflective surface, and a second reflective surface, the first reflective surface and the second reflective surface intersecting the light-transmitting surface respectively, the light-transmitting surface having a first light-incident area, a first light-exiting area, and a reflective area, the reflective area being located between the first light-incident area and the first light-exiting area;

[0018] The prism is used to reflect light rays incident from the first incident light region sequentially through the first reflecting surface, the reflecting region, and the second reflecting surface before exiting from the first exit light region.

[0019] In this way, the prism is trapezoidal, allowing light to undergo three total internal reflections within it. This means the optical path length of the light within the prism is relatively long, resulting in a larger focal length for a camera module of the same size. Alternatively, it allows the camera module to occupy less space while maintaining the same focal length.

[0020] In some possible implementations, the housing assembly includes a housing and a first frame, the first frame being located within the housing and slidably connected to the housing;

[0021] The first lens assembly and the second lens assembly are respectively connected to the first frame;

[0022] The first drive assembly is used to drive the first frame to slide along a first straight line and / or a second straight line, wherein the first straight line and the second straight line are coplanar and perpendicular to the axis.

[0023] In this way, the first drive component can drive the first frame to move in a plane perpendicular to the axis, thereby realizing the image stabilization function of the camera module.

[0024] In some possible implementations, the first driving component includes a first magnet, a second magnet, a first electromagnetic element, and a second electromagnetic element;

[0025] The first magnet and the second magnet are respectively connected to the first frame;

[0026] The first electromagnetic component is connected to the housing and is arranged opposite to the first magnet along the first straight line. The first electromagnetic component is used to attract or repel the first magnet.

[0027] The second electromagnetic component is connected to the housing and is arranged opposite to the second magnet along the second straight line. The second electromagnetic component is used to attract or repel the second magnet.

[0028] In this way, by switching the working states of the first electromagnetic component and the second electromagnetic component, the first drive assembly can drive the first frame to move in a plane perpendicular to the axis. The structure of the first drive assembly is simple.

[0029] In some possible implementations, the first frame has a hollow cubic structure, with the first mirror group and the second mirror group respectively located within the first frame.

[0030] It is understood that the first and second scope groups being located within the first frame means that at least a portion of the first and second scope groups are located within the first frame, while a portion of the first and second scope groups may be located outside the first frame.

[0031] This reduces the overall size of the camera module along the axial direction, i.e., reduces the thickness of the camera module, which is beneficial for miniaturizing the camera module design.

[0032] In some possible implementations, the camera module further includes a second drive component for driving the second lens group to move along the axis.

[0033] In this way, the position of the first lens group remains unchanged along the axis, and the second lens group is driven to move along the axis by the second drive component, so that the distance between the second lens group and the first lens group can be adjusted to achieve focusing of the camera module.

[0034] In some possible implementations, the second drive assembly includes a second frame, a third magnet, and a third electromagnetic component;

[0035] The second frame is located within the housing assembly and is slidable relative to the housing assembly along the axis; the second frame is connected to the second lens group.

[0036] The third magnet is connected to the second frame;

[0037] The third electromagnetic component is connected to the housing assembly. The third electromagnetic component is used to excite a first magnetic field or a second magnetic field. The first magnetic field has a third-direction magnetic force on the third magnet, and the second magnetic field has a fourth-direction magnetic force on the third magnet. The third-direction and the fourth-direction are opposite to each other and are parallel to the optical axis of the second mirror group.

[0038] In this way, by switching the working state of the third electromagnetic component, the first magnetic field or the second magnetic field can be excited, thereby driving the second frame to move along the axis and realizing the focusing of the camera module. The structure of the second drive component is simple.

[0039] On the other hand, this disclosure provides an electronic device that includes a camera module as described in the first aspect and its possible implementations.

[0040] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0041] This disclosure provides a camera module in which a first lens group and a second lens group are respectively arranged opposite to a first light-receiving area. This allows both the first and second lens groups to extend along the length and width of the electronic device, without being limited by the thickness of the electronic device. Therefore, the sizes of the first and second lens groups can be set larger, thereby increasing the overall light intake of the camera module and shortening the exposure time required for shooting, thus improving the image stabilization capability of the camera module.

[0042] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0068] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0069] With the continuous development of mobile imaging devices, such as smartphones, camera modules in electronic devices are becoming increasingly feature-rich. Most smartphones incorporate periscope lenses to meet consumers' needs for long-distance shooting. Currently, a periscope lens consists of a housing, a prism, a lens group, and an image sensor. The prism, lens group, and image sensor are all housed within the housing, which has a light-transmitting area. The object-side surface of the prism is positioned opposite the light-transmitting area, and the image sensor is positioned opposite the image-side surface of the prism. The lens group is positioned between the image-side surface and the image sensor. Light passes through the light-transmitting area, is refracted by the prism, and then transmitted through the lens group to reach the image sensor. However, in this structure, the lens group is positioned between the prism and the image sensor. The size of the lens group is limited by the thickness of the electronic device, resulting in a smaller amount of light entering the camera module. This leads to a longer exposure time required for shooting, resulting in poor image stabilization performance.

[0070] To address the aforementioned technical problems, this disclosure provides a camera module, such as... Figure 1 As shown, the camera module includes a housing assembly 1, a prism 2, a first lens group 3, a second lens group 4, an image sensor 5, and a first driving assembly 6 (the first driving assembly 6 is not shown in the image). Figure 1 (as shown in the image).

[0071] The housing assembly 1 has a light-transmitting region 10. The prism 2 has a first light-incident region 2a and a first light-exiting region 2b, with the first light-incident region 2a arranged opposite to the light-transmitting region 10. A first mirror group 3 and a second mirror group 4 are spaced apart in the light-incident direction of the prism 2 and are respectively arranged opposite to the first light-incident region 2a. An image sensor 5 is arranged opposite to the first light-exiting region 2b. A first driving assembly 6 is used to drive the first mirror group 3 and the second mirror group 4 to move in a direction perpendicular to the axis 101 of the light-transmitting region 10.

[0072] Using the technical solution provided in this embodiment, the extension direction of the first light-incident area 2a of the prism 2 can be set in the length and width direction of the electronic device. The first lens group 3 and the second lens group 4 are respectively arranged opposite to the first light-incident area 2a, so that both the first lens group 3 and the second lens group 4 extend in the length and width direction of the electronic device and are not limited by the thickness of the electronic device. Therefore, the size of the first lens group 3 and the second lens group 4 can be set to be larger, thereby increasing the overall light intake of the camera module and shortening the exposure time required for the camera module to shoot, thereby improving the image stabilization capability of the camera module.

[0073] The following is a description of each part of the camera module:

[0074] Housing assembly 1 is a component in the camera module used to house other parts.

[0075] In some possible embodiments, housing assembly 1 includes multiple parts, such as Figure 2 As shown, the housing assembly 1 includes a housing 11 and a first frame 12.

[0076] Specifically, see Figure 2 The housing 11 includes a top cover 111, a frame 112, and a base 113. The frame 112 has a hollow cubic structure, and both its top and bottom walls have openings. The top cover 111 has a cubic lid-like structure, and its top wall has a light-transmitting area 10, which can be a through-hole structure or a transparent area within the top cover 111. The top cover 111 can be fitted over the frame 112, and its top wall covers the opening in the top wall of the frame 112. The base 113 has a plate-like structure, and it covers the opening in the bottom wall of the frame 112. The side of the base 113 closest to the frame 112 has a prism mounting structure 113a, which accommodates and limits the prism 2. In practice, the top cover 111, frame 112, and base 113 are detachably connected. See [reference needed]. Figure 2 and Figure 3 The top cover 111, frame 112 and base 113 are assembled to form a receiving cavity, which is used to receive the prism 2, the first mirror group 3, the second mirror group 4 and the first drive assembly 6.

[0077] Further, see Figure 2 The first frame 12 has a hollow cubic structure. The first frame 12 is located inside the frame 112, and the first frame 12 and the frame 112 are slidably connected in a direction perpendicular to the axis 101, so that the first frame 12 can move relative to the shell 11 in a plane perpendicular to the axis 101.

[0078] In some examples, the inner side of the bottom wall of the frame 112 has a groove structure 112a, and the housing assembly 1 also includes a plurality of first balls 13 disposed in the groove structure 112a and in contact with the bottom wall of the frame 112 and the first frame 12, respectively. In this way, the first frame 12 can slide within the frame 112 via the first balls 13, which can reduce the friction between the first frame 12 and the frame 112.

[0079] For example, the number of the first ball 13 can be three or four. Figure 2 (Only one is shown in the figure) Multiple first balls 13 can be respectively set at the top corner of the bottom wall of the first frame 12. Correspondingly, the inner side of the bottom wall of the frame 112 has three or four sliding groove structures 112a, each sliding groove structure 112a is used to accommodate one first ball 13.

[0080] Prism 2 is a component in the camera module used to change the direction of light. In the periscope camera module, light enters the interior of prism 2 through the first light-incident area 2a, and then exits prism 2 through the first light-out area 2b after being reflected at least once inside prism 2.

[0081] In some possible embodiments, the first light-incident region 2a and the first light-outceasing region 2b face the same direction.

[0082] like Figure 1 As shown, both the first light-incident region 2a and the first light-exiting region 2b face upwards in the figure. Thus, the first light-exiting region 2b also extends along the length and width of the electronic device. Since the image sensor 5 is arranged opposite to the first light-exiting region 2b, the image sensor 5 can extend along the length and width of the electronic device. The size of the image sensor 5 is not limited by the thickness of the electronic device, and its size can be set larger, thereby improving the imaging quality of the camera module.

[0083] In some examples, prism 2 is a trapezoidal prism.

[0084] like Figure 1 and Figure 2 As shown, prism 2 has a trapezoidal prism structure with an isosceles trapezoidal cross-section. Prism 2 has a light-transmitting surface 21, a first reflecting surface 22, and a second reflecting surface 23. The light-transmitting surface 21, the first reflecting surface 22, and the second reflecting surface 23 are three adjacent sides of the trapezoidal prism structure. The first reflecting surface 22 and the second reflecting surface 23 intersect with the light-transmitting surface 21. The light-transmitting surface 21 has a first incident light region 2a, a first exit light region 2b, and a reflecting region 2c, with the reflecting region 2c located between the first incident light region 2a and the first exit light region 2b.

[0085] In implementation, see Figure 1Light enters the prism 2 through the first light-incident area 2a, and then passes through the first reflecting surface 22, the reflecting area 2c, and the second reflecting surface 23 in sequence to the first light-out area 2b. Finally, the light exits the prism 2 through the first light-out area 2b and is directed to the image sensor 5 for imaging.

[0086] In this way, light can undergo three total internal reflections within prism 2, meaning the optical path length of the light within prism 2 is relatively long. This allows the camera module to have a longer focal length for the same size. Alternatively, it allows the camera module to occupy less space while maintaining the same focal length.

[0087] In some possible embodiments, the prism 2 has a triangular prism structure, and the first light-incident region 2a and the first light-outcrystal region 2b correspond to the object side and image side that are perpendicular to each other in the prism 2, respectively.

[0088] The first lens group 3 and the second lens group 4 are components in the camera module used to achieve focusing and image stabilization functions.

[0089] like Figure 1 and Figure 2 As shown, the first lens group 3 and the second lens group 4 are arranged at intervals along the axis 101 of the light-transmitting area 10, and are respectively arranged opposite to the first light-receiving area 2a. The first lens group 3 and the second lens group 4 can move in a plane perpendicular to the axis 101 to achieve image stabilization. In addition, the second lens group 4 can also move towards or away from the first lens group 3 to achieve focusing. The principle of how the first lens group 3 and the second lens group 4 move will be described in detail below when introducing the first drive assembly 6 and the second drive assembly 7, and will not be described in detail here.

[0090] Using the technical solution provided in this disclosure, the camera module achieves focusing and image stabilization by moving the first lens group 3 and the second lens group 4. Compared with the camera module in the related art that achieves focusing and image stabilization by moving the prism 2, the control is simpler and the control accuracy is higher.

[0091] In some examples, the first mirror assembly 3 includes a first mirror assembly body 31 and a first connecting frame 32.

[0092] like Figure 2 As shown, the first lens assembly body 31 includes a first lens barrel portion and a first lens portion. The first lens portion is fixed inside the first lens barrel portion and includes at least one lens. A first connecting frame 32 is fitted outside the first lens barrel portion and is fixedly connected to the first lens barrel portion. The first connecting frame 32 is also fixedly connected to the first frame 12.

[0093] Furthermore, the second lens group 4 includes a second lens barrel portion and a second lens portion, the second lens portion being fixed inside the second lens barrel portion, and the second lens portion including at least one lens. The second lens barrel portion is tractively connected to the second drive assembly 7, and the second lens group 4 can move along axis 101 under the drive of the second drive assembly 7 to achieve focusing of the camera module.

[0094] The number of lenses in the first and second lens barrels can be set by technicians according to actual needs, and this disclosure does not limit this.

[0095] In some possible embodiments, see Figure 2 The first lens group 3 is located within the light-transmitting area 10.

[0096] like Figure 1 and Figure 2 As shown, the light-transmitting area 10 is a circular, unobstructed area, and its size is larger than the outer diameter of the first lens group 3. At least a portion of the first lens group 3 is located within the light-transmitting area 10. A portion of the first lens group 3 is located within the light-transmitting area 10, while another portion extends beyond the light-transmitting area 10 and beyond the housing assembly 1. This prevents the edge of the light-transmitting area 10 from obstructing the first lens group 3, further increasing the amount of light entering the camera module and thus further improving the image stabilization performance of the camera module.

[0097] In some possible embodiments, the first drive assembly 6 drives the first mirror group 3 and the second mirror group 4 to move via electromagnetic force.

[0098] like Figure 2 As shown, the first lens group 3 and the second lens group 4 are respectively housed within the first frame 12. (See also...) Figure 3 and Figure 4 The first driving assembly 6 includes a first magnet 61, a second magnet 62, a first electromagnetic component 63, and a second electromagnetic component 64. The first magnet 61 and the second magnet 62 are respectively connected to the first frame 12. The first electromagnetic component 63 is connected to the housing 11 and is arranged opposite to the first magnet 61 along a first straight line O1. The first electromagnetic component 63 is used to attract or repel the first magnet 61. The second electromagnetic component 64 is connected to the housing 11 and is arranged opposite to the second magnet 62 along a second straight line O2. The second electromagnetic component 64 is used to attract or repel the second magnet 62.

[0099] Among them, the first line 01 and the second line 02 are coplanar, and the first line 01 and the second line 02 are perpendicular to each other and perpendicular to the axis 101 respectively.

[0100] Specifically, see Figure 3The first frame 12 has a hollow cubic structure and four connected side walls. The first magnet 61 is arranged on the first side wall, and the second magnet 62 is arranged on the second side wall. The first side wall and the second side wall are two adjacent side walls of the first frame 12. The first electromagnetic component 63 is arranged on the inner wall of the frame 112 and is arranged opposite to the first magnet 61. The second electromagnetic component 64 is arranged on the inner wall of the frame 112 and is arranged opposite to the second magnet 62.

[0101] For example, the first magnet 61 and the second magnet 62 are both magnets, and the first electromagnetic component 63 and the second electromagnetic component 64 are both coils. The first magnet 61 and the second magnet 62 both have a plate-like structure, and the polarities of the side of the first magnet 61 that is in contact with the first frame 12 and the side that is away from the first frame 12 are different.

[0102] For example, the first magnet 61 and the second magnet 62 are respectively bonded to the first frame 12, and the first electromagnetic component 63 and the second electromagnetic component 64 are respectively bonded to the frame 112.

[0103] In implementation, see Figure 4 By controlling the direction of the current flowing through the first electromagnetic component 63, magnetic fields in different directions can be generated, thereby attracting or repelling the first magnet 61 along the first straight line 01. Similarly, by controlling the direction of the current flowing through the second electromagnetic component 64, magnetic fields in different directions can be generated, thereby attracting or repelling the second magnet 62 along the second straight line 02. It is easy to understand that during the process of the first electromagnetic component 63 attracting or repelling the first magnet 61 and the second electromagnetic component 64 attracting or repelling the second magnet 62, the first frame 12 moves within the frame 112. Since the first mirror group 3 and the second mirror group 4 are respectively arranged within the first frame 12, the first mirror group 3 and the second mirror group 4 will also move accordingly, thereby driving the first mirror group 3 and the second mirror group 4 to move in a plane perpendicular to the axis 101 through the first driving component 6.

[0104] In some possible embodiments, the camera module also includes a second driving component 7.

[0105] like Figure 2 As shown, the second drive assembly 7 is connected to the first frame 12 and the second lens group 4 respectively. The second drive assembly 7 is used to drive the second lens group 4 to move along the axis 101, thereby realizing the focusing of the camera module.

[0106] In some examples, the second drive component 7 includes a second frame 71, a third magnet 72, and a third electromagnetic element 73.

[0107] like Figure 5As shown, the second frame 71 is located inside the housing assembly 1, and the second frame 71 can move and slide relative to the housing assembly 1 along a third direction 03 or a fourth direction 04. The second frame 71 is connected to the second mirror group 4, the third magnet 72 is connected to the second frame 71, and the third electromagnetic component 73 is connected to the housing assembly 1.

[0108] Among them, the third direction 03 or the fourth direction 04 are opposite and are parallel to axis 101 respectively.

[0109] Specifically, see Figure 2 and Figure 5 The third side wall of the first frame 12 has a receiving cavity, and the third electromagnetic component 73 is disposed in the receiving cavity, wherein the third side wall and the second side wall are two opposite side walls of the first frame 12.

[0110] In one example, see Figure 2 The third magnet 72 is a magnet, and the two sides of the third magnet 72 located along the axis 101 have opposite polarities. The third electromagnetic component 73 is a coil.

[0111] In implementation, see Figure 5 By controlling the direction of the current within the third electromagnetic component 73, the third electromagnetic component 73 can generate a first magnetic field or a second magnetic field. The first magnetic field exerts a magnetic force in a third direction (O3) on the third magnet 72, and the second magnetic field exerts a magnetic force in a fourth direction (O4) on the third magnet 72. Specifically, when the direction of the current within the third electromagnetic component 73 is positive, the third electromagnetic component 73 can generate the first magnetic field, thereby causing the second frame 71 and the second mirror assembly 4 to move along the third direction (O3), so that the second mirror assembly 4 gradually approaches the first mirror assembly 3. Correspondingly, when the direction of the current within the third electromagnetic component 73 is negative, the third electromagnetic component 73 can generate the second magnetic field, thereby causing the second frame 71 and the second mirror assembly 4 to move along the fourth direction (O4), so that the second mirror assembly 4 gradually moves away from the first mirror assembly 3.

[0112] In one example, the second drive component 7 also includes a plurality of second balls 74, such as Figure 2 As shown, the outer wall of the second frame 71 is provided with two sliding groove structures, which are parallel to the axis 101. Multiple second balls 74 are respectively disposed in these two sliding groove structures, and the second balls 74 abut against the second frame 71 and the frame 112. Furthermore, the two sliding groove structures can be located on the same side wall of the second frame 71. In this way, the first frame 12 and the second frame 71 can slide against each other via the first balls 13, which can reduce the friction between the first frame 12 and the second frame 71.

[0113] In some possible embodiments, the camera module also includes a first Hall element 8, a second Hall element 9, and a control unit.

[0114] like Figure 2 and Figure 3 As shown, there are two first Hall elements 8, one of which is disposed in the first electromagnetic component 63, and the other is disposed in the second electromagnetic component 64.

[0115] In practice, the two first Hall elements 8 are electrically connected to the control unit. When the positions of the first magnet 61 and the second magnet 62 change, the first voltage generated by the magnetic field excited by the first magnet 61 and the second magnet 62 on the two first Hall elements 8 will change. The control unit can receive the first voltage signal corresponding to the first voltage, thereby determining the position of the frame 112, and thus realizing real-time detection of the position of the first mirror group 3 and the second mirror group 4 in the plane perpendicular to the axis 101.

[0116] Furthermore, such as Figure 2 As shown, the second Hall element 9 is disposed within the third electromagnetic element 73.

[0117] In practice, the second Hall element 9 is electrically connected to the control unit. When the position of the third magnet 72 changes, the second voltage generated by the magnetic field excited by the third magnet 72 on the second Hall element 9 will change. The control unit can receive the second voltage signal corresponding to the second voltage to determine the position of the second frame 71, thereby realizing real-time detection of the position of the second mirror group 4 on the axis 101.

[0118] The technical solutions provided in this disclosure have at least the following beneficial effects:

[0119] This disclosure provides a camera module in which a first lens group 3 and a second lens group 4 are respectively arranged opposite to a first light-receiving region 2a. This allows both the first lens group 3 and the second lens group 4 to extend along the length and width of the electronic device, without being limited by the thickness of the electronic device. Therefore, the sizes of the first lens group 3 and the second lens group 4 can be set larger, thereby increasing the overall light intake of the camera module and shortening the exposure time required for shooting, thus improving the image stabilization capability of the camera module.

[0120] This disclosure also provides an electronic device that includes the camera module described above.
