Description

Technical Field

[0001] The present application belongs to the field of electronic technology, and specifically relates to a camera module and electronic equipment. Background Art

[0002] With the widespread use of mobile devices in our lives, people's demands for their camera functions are increasing. To meet users' diverse shooting needs, some mobile devices are equipped with standard lenses, wide-angle lenses, and telephoto lenses. Telephoto lenses, due to their long focal length, narrow angle of view, and short depth of field, can capture larger images at the same distance than standard lenses and highlight the focused subject, making them ideal for capturing distant people or scenes.

[0003] Traditional telephoto lenses have a long optical path and large back focus, resulting in a large length, making them difficult to integrate into very thin mobile devices. To address this, current mobile phones primarily use periscope lenses to reduce the lens's size relative to the device's thickness. However, this approach actually sacrifices space in the X and Y directions to reduce space occupied in the Z direction, and does not reduce the actual space occupied by the lens. In mobile devices with very limited internal space, the lens still has a significant negative impact on the layout of other components. Summary of the Invention

[0004] The present application aims to provide a camera module and electronic equipment, which at least solves the problem that the lens of the periscope camera in the current mobile terminal device occupies a large space.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a camera module, comprising:

[0007] A housing, wherein a light hole is provided on the housing, and a periscope is provided inside the housing, and the periscope is used to reflect the light beam incident from the light hole to the periscope;

[0008] A reflector group and an image sensor are both disposed in the housing, the reflector group including a plurality of reflectors, the plurality of reflectors including at least a first reflector and a second reflector; the first reflector is disposed on a reflective light path of the periscope surface, and is configured to receive and reflect a light beam reflected from the periscope surface; the second reflector is disposed off-axis from the periscope surface, and is configured to emit the light beam in the reflector group to the image sensor;

[0009] A driving mechanism, wherein at least one of the plurality of reflecting mirrors is connected to the housing via the driving mechanism, and the driving mechanism is used to adjust at least one of a deflection angle of the reflecting mirror and a position of the reflecting mirror in the housing.

[0010] In a second aspect, an embodiment of the present application provides an electronic device, including:

[0011] case;

[0012] The camera module is any one of the above-mentioned camera modules, and the camera module is arranged in the shell.

[0013] In an embodiment of the present application, a periscope mirror and a reflector group having multiple reflectors are provided, and the periscope mirror is used to reflect the light beam incident on the camera module along the Z direction into the reflector group. Then, the multiple reflectors in the reflector group are used to reflect the reflected light beam from the periscope mirror multiple times and emit it from the reflector group. By folding the light path, the transmission path of the light beam in the camera module is extended, thereby improving the magnification. When a certain long focal length is met, the light path is compressed in the X and Y directions, and the utilization rate of the camera module in the X and Y directions is improved, which is conducive to the miniaturization design of the camera module and reduces the space occupied by the camera module in the mobile terminal device. At least one of the reflectors is connected to the housing through a driving mechanism. By adjusting the deflection angle of the reflector through the driving mechanism, the camera module can automatically calibrate the imaging position incident on the image sensor; by adjusting the position of the reflector in the housing through the driving mechanism, the camera module can automatically focus.

[0027] The following combination Figures 1-6 Describe the camera module and electronic device according to the embodiments of the present application.

[0028] The embodiment of the present application proposes a camera module, such as Figure 1 and Figure 2As shown, the camera module of some embodiments of the present application includes a housing 1, a reflector group 2, an image sensor 5 and a driving mechanism 3. The housing 1 is provided with a light hole 11, and a periscope surface 41 is provided inside the housing 1. The periscope surface 41 is used to reflect the light beam incident from the light hole 11 to the periscope surface 41. The reflector group 2 and the image sensor 5 are both arranged in the housing 1 and include multiple reflectors. The multiple reflectors include at least a first reflector 21 and a second reflector 22. The first reflector 21 is arranged on the reflection light path of the periscope surface 41, and is used to receive and reflect the reflected light beam from the periscope surface 41. The second reflector 22 is arranged off-axis with the periscope surface 41, and is used to emit the light beam in the reflector group 2 to the image sensor 5. At least one of the multiple reflectors is connected to the housing 1 via a driving mechanism 3, and the driving mechanism 3 is used to adjust at least one of the deflection angle of the reflector and the position of the reflector in the housing 1.

[0029] Specifically, the multiple reflectors of the reflector assembly 2 are generally mounted on an inner sidewall of the housing 1 corresponding to the XY plane. The periscope surface 41 is tilted relative to the XY plane. The axis of the light hole 11 is perpendicular to the XY plane, that is, arranged along the Z direction. A light-transmitting cover plate 7 is provided at the light hole 11.

[0030] When in use, the light beam of the object being photographed outside the camera module is incident on the periscope mirror 41 through the light hole 11 along the Z direction, is reflected by the periscope mirror 41, and is incident on the reflector group 2, and then is reflected in sequence by multiple reflectors of the reflector group 2 and is emitted to the photosensitive surface of the image sensor 5.

[0031] It can be understood that the reflector group 2 includes at least two reflectors. The light beam incident to the reflector group 2 is reflected for the first time by the first reflector 21 and for the last time by the second reflector 22, and finally the light beam incident to the reflector group 2 is reflected onto the corresponding image sensor 5.

[0032] The second reflector 22 is off-axis from the periscope surface 41, that is, the second reflector 22 is located on one side of the reflection light path of the periscope surface 41. In this way, the light beam incident into the reflector assembly 2 can be folded when reflected by the first reflector 21 and the second reflector 22.

[0033] The first reflector 21 folds and reflects the incident light beam from the reflector assembly 2, such that the reflected light path of the first reflector 21 forms an angle with the incident light path and partially overlaps. The second reflector 22 folds and reflects the incident light beam, such that the reflected light path of the second reflector 22 forms an angle with the incident light path and partially overlaps. Thus, the double folding and reflection by the first reflector 21 and the second reflector 22 lengthens the light beam's transmission path within the reflector assembly 2, thereby increasing the magnification.

[0034] In an optional embodiment, the drive mechanism 3 is used to drive the reflector connected thereto to rotate, thereby adjusting the deflection angle of the reflector. For example, the rotation axis of the reflector is parallel to the XY plane, that is, the drive mechanism 3 is used to drive the pitch angle of the reflector relative to the XY plane. For another example, the rotation axis of the reflector is parallel to the Z direction, that is, the drive mechanism 3 is used to drive the rotation angle of the reflector relative to the Z direction. When the imaging of the camera module is offset due to temperature rise, jitter or mechanical assembly deviation, the deflection angle of the reflector can be adjusted by the drive mechanism 3 to automatically calibrate the imaging position on the image sensor 5, thereby adjusting the imaging quality.

[0035] In an optional embodiment, the drive mechanism 3 is used to drive the reflector connected thereto to move within the housing 1, thereby changing the reflector's position within the housing 1 and thereby changing its relative distance from other reflectors. It will be understood that the drive mechanism 3 is used to adjust the reflector's position relative to the housing 1 in two or three dimensions. When the camera module's focal length needs to be adjusted, the drive mechanism 3 can be used to drive the reflector to increase or decrease the distance between it and the other reflectors, thereby achieving autofocus (AF) of the camera module.

[0036] For example, the drive mechanism 3 includes a universal joint, and the reflector is connected to the universal joint. For another example, the drive mechanism 3 includes a first drive member and a second drive member, wherein the driving end of the first drive member is connected to the reflector to drive the reflector to translate along the X direction, and the driving end of the second drive member is connected to the first drive member to drive the first drive member to move along the Y direction. Furthermore, the drive mechanism 3 also includes a third drive member, wherein the driving end of the third drive member is connected to the second drive member to drive the second drive member to move along the Z direction. Optionally, the drive mechanism adopts a micro-electromechanical system (MEMS) micromotor.

[0037] In an optional embodiment, the driving mechanism 3 is used to drive the reflector connected thereto to rotate and move, that is, the deflection angle of the reflector and its position in the housing 1 can be adjusted through the driving mechanism 3, so that the reflector has a higher degree of freedom, thereby realizing optical automatic focusing of the camera module and adjustment of the imaging quality.

[0038] In an optional embodiment, there are multiple driving mechanisms 3, and the multiple driving mechanisms 3 are arranged in a one-to-one correspondence with the multiple reflectors of the reflector group 2. Each driving mechanism 3 is used to adjust the deflection angle of the corresponding reflector and drive the reflector to move, making the automatic focusing and automatic calibration of the camera module more flexible.

[0039] The camera module proposed in the embodiment of the present application is provided with a periscope mirror 41 and a reflector assembly 2 having multiple reflectors. The periscope mirror 41 is used to reflect a light beam incident on the camera module along the Z direction into the reflector assembly 2. The multiple reflectors in the reflector assembly 2 then reflect the light beam reflected from the periscope mirror 41 multiple times and emit it from the reflector assembly 2. By folding the optical path, the transmission path of the light beam within the camera module is extended, thereby improving the magnification. While meeting a certain long focal length, the optical path is compressed in the X and Y directions, improving the utilization rate of the camera module in the X and Y directions, facilitating the miniaturization design of the camera module and reducing the space occupied by the camera module in the mobile terminal device. At least one of the reflectors is connected to the housing 1 via a drive mechanism 3. By adjusting the deflection angle of the reflector through the drive mechanism 3, the camera module can automatically calibrate the imaging position of the incident image on the image sensor 5; by adjusting the position of the reflector within the housing 1 through the drive mechanism 3, the camera module can automatically focus.

[0040] In some embodiments of the present application, Figure 2 and Figure 4 As shown, the reflector assembly 2 further includes at least one third reflector 23. The at least one third reflector 23 is configured to receive the reflected light beam from the first reflector 21 and reflect it to the second reflector 22. It will be appreciated that the reflector assembly 2 includes at least three reflectors. In the optical path within the reflector assembly 2, at least one third reflector 23 is positioned between the first reflector 21 and the second reflector 22. The third reflector 23 acts as an intermediate reflector, reflecting the reflected light beam from the first reflector 21 to the second reflector 22, thereby increasing the number of folds and reflections of the light beam reflected from the periscope surface 41 by the reflector assembly 2.

[0041] The second reflector 22 and the at least one third reflector 23 are located on both sides of the reflective light path of the periscope surface 41. It is understood that at least one third reflector 23 and the second reflector 22 are located on both sides of the reflective light path of the periscope surface 41, respectively, so that the reflected light beam of at least one third reflector 23 intersects with the reflected light beam of the periscope surface 41, thereby reusing part of the reflective light path space of the periscope surface 41 and improving the spatial compression rate.

[0042] See also Figure 2 If the number of the third reflector 23 is one, the second reflector 22 and the third reflector 23 are respectively arranged on both sides of the reflection light path of the periscope mirror surface 41.

[0043] If there are multiple third reflectors 23, at least one of the multiple third reflectors 23 and the second reflector 22 is located on one side of the reflection light path of the periscope surface 41, and the other third reflectors 23 are located on the other side of the reflection light path of the periscope surface 41. The reflected light beam from the first reflector 21 is reflected multiple times by the multiple third reflectors 23 in sequence and then emitted to the second reflector 22. Figure 4 There are two third reflectors 23 , one third reflector 23 and the second reflector 22 are located on one side of the reflected light path of the periscope mirror surface 41 , and the other third reflector 23 is located on the other side of the reflected light path of the periscope mirror surface 41 .

[0044] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the reflected light beam of at least the second reflector 22 among the multiple reflectors of the reflector group 2 intersects the reflected light beam of the periscope surface 41. It can be understood that the second reflector 22 and the image sensor 5 are respectively located on both sides of the reflected light path of the periscope surface 41.

[0045] In this embodiment, on the basis of the folded optical path of the first reflector 21 and the second reflector 22, there is at least partial overlap between the reflected optical path of the second reflector 22 and the reflected optical path of the periscope surface 41, that is, the reflected optical path of the second reflector 22 and the reflected optical path of the periscope surface 41 share a part of the optical path space, further compressing the optical path space of the camera module.

[0046] See also Figure 3 In the case where the reflector group 2 consists of only the first reflector 21 and the second reflector 22, the reflective light path of the second reflector 22 shares a portion of the optical path space with the reflective light path of the periscope surface 41. At the same time, the reflective light path of the first reflector 21 shares a portion of the optical path space with the reflective light paths of the periscope surface 41 and the second reflector 22.

[0047] See also Figure 2 , there is one third reflector 23, and the second reflector 22 and the third reflector 23 are respectively located on either side of the reflected light path of the periscope surface 41. In this case, the reflected light paths of the first reflector 21, the second reflector 22, and the third reflector 23 partially overlap with the reflected light path of the periscope surface 41, that is, the reflected light path of each reflector shares a portion of the optical path space with the reflected light path of the periscope surface 41.

[0048] If the first reflector 21 and the third reflector 23 are located on either side of the reflection light path of the second reflector 22, the reflection light path of the second reflector 22 and the reflection light path of the first reflector 21 also share a portion of the optical path space. If the first reflector 21 and the third reflector 23 are located on the same side of the reflection light path of the second reflector 22, only the first reflector 21 and the second reflector 22 share a portion of the optical path space with the reflection light path of the periscope surface 41.

[0049] like Figure 2-Figure 4 As shown, in some embodiments of the present application, the reflected light beam of the second reflector 22 among the multiple reflectors of the reflector group 2 intersects with the reflected light beam of at least one other reflector. The at least one other reflector includes at least one of the reflectors in the reflector group 2 other than the second reflector 22. Thus, in this embodiment, based on the folded light paths of the first reflector 21 and the second reflector 22, the reflected light path of the second reflector 22 partially overlaps with the reflected light path of the at least one other reflector, that is, the reflected light path of the second reflector 22 and the reflected light path of the at least one other reflector share a portion of the light path space, further compressing the light path space of the camera module.

[0050] See also Figure 3 In the case where the reflector assembly 2 consists of only the first reflector 21 and the second reflector 22, the reflected light beam from the second reflector 22 intersects with the reflected light beam from the first reflector 21 in an area near the second reflector 22. Furthermore, the periscope surface 41 and the first reflector 21 are located on either side of the reflected light beam from the second reflector 22, respectively. Thus, the three light paths, namely the light path reflected by the periscope surface 41, the light path reflected by the first reflector 21, and the light path reflected by the second reflector 22, overlap with each other, thus fully compressing the light path space.

[0051] See also Figure 2 There is one third reflector 23, and the second and third reflectors 22 and 23 are located on either side of the reflected light path of the periscope surface 41, respectively. The first and third reflectors 21 and 23 are located on either side of the reflected light path of the second reflector 22, respectively. In this case, the reflected light beam from the second reflector 22 partially overlaps with the reflected light beams from the first and third reflectors 21 and 23, meaning that the reflected light paths of the first and third reflectors 21 and 23 share a portion of the optical path space with the reflected light path of the second reflector 22. Furthermore, the reflected light paths of the first, second, and third reflectors 21, 22, and 23 partially overlap with the reflected light path of the periscope surface 41, meaning that the reflected light paths of each reflector share a portion of the optical path space with the reflected light path of the periscope surface 41. This embodiment, while further increasing the magnification by adding a third reflector 23, fully compresses the optical path space.

[0052] See also Figure 4 There are two third reflectors 23, one on each side of the reflection path of the periscope mirror 41 and the other on each side of the reflection path of the second reflector 22. The light beam reflected by the first reflector 21 is sequentially reflected by the two third reflectors 23 and then emitted to the second reflector 22.

[0053] Specifically, one of the third reflectors 23 and the second reflector 22 is located on one side of the reflected light path of the periscope surface 41, while the other third reflector 23 is located on the other side of the reflected light path of the periscope surface 41. Furthermore, one of the third reflectors 23 is located on one side of the reflected light path of the second reflector 22, while the other third reflector 23 and the first reflector 21 are located on the other side of the reflected light path of the second reflector 22. Thus, the reflected light path from one of the third reflectors 23 to the other third reflector 23 partially overlaps with the reflected light path from the periscope surface 41 and also partially overlaps with the reflected light path from the second reflector 22. This embodiment, while further increasing the magnification by adding two third reflectors 23, fully compresses the optical path space.

[0054] Among them, such as Figure 4 As shown, the reflected light beam of the second reflector 22 does not intersect with the reflected light beam of the periscope mirror 41. Figure 4 The positions of the periscope mirror surface 41 and the image sensor 5 are such that the reflected light beam of the second reflecting mirror 22 intersects with the reflected light beam of the periscope mirror surface 41 .

[0055] In some embodiments of the present application, the periscope mirror surface 41 is tilted relative to the XY plane, and the periscope mirror surface 41 and the photosensitive surface of the image sensor 5 are extended in the same direction in the XY plane direction (see Figure 4 ), or, the periscope mirror surface 41 and the photosensitive surface of the image sensor 5 are respectively extended along two mutually perpendicular directions in the XY plane direction (see Figure 2 and Figure 3 This can facilitate the setting of the relative position of the image sensor 5 and the periscope mirror 41, which is conducive to simplifying the design and assembly process.

[0056] It is understood that in some embodiments of the present application, the first reflector 21, the second reflector 22, and one or more third reflectors 23 are distributed in a polygonal shape. The reflective surfaces of the first reflector 21, the second reflector 22, and the third reflector 23 are all facing the inside of the polygon. The reflected light beam from the periscope surface 41 is incident on the interior of the polygon, and after being sequentially reflected by the multiple reflectors of the reflector assembly 2 inside the polygon, it is emitted from the interior of the polygon.

[0057] Furthermore, during the process of multiple reflections of the light beam in the reflector group 2, the incident light beam of the reflector group 2 (i.e., the reflected light beam of the periscope mirror 41) intersects with the reflected light beam of each reflector, and the outgoing light beam of the reflector group 2 (i.e., the reflected light beam of the second reflector 22) intersects with the reflected light beams of all other reflectors except the second reflector 22. In this way, the optical path space in the reflector group 2 can be compressed to a great extent, thereby reducing the overall volume of the camera module.

[0058] In a specific embodiment of the present application, the reflector group 2 includes a first reflector 21, a second reflector 22, and a third reflector 23. Taking a 1 / 2" inch complementary metal oxide semiconductor (CMOS) image sensor as an example, a telephoto system with an equivalent focal length of 10x (relative to a conventional 1x focal length of 25mm) is designed. The first reflector 21, the second reflector 22, and the third reflector 23 are arranged in a Figure 2 The arrangement shown in FIG. 2 shows that the light beam in the reflector group 2 is as follows: Figure 5 In the transmission state shown, the incident light path of the first reflector 21, the reflected light path of the first reflector 21, the reflected light path of the second reflector 22 and the reflected light path of the third reflector 23 are in Figure 5 There is optical path overlap in the circled area A. The first reflector 21 is a spherical surface, the second reflector 22 is a free-form surface, and the third reflector 23 is an even-order aspheric surface. The parameters of the three reflectors are shown in Tables 1 and 2:

[0063]

[0064]

[0065] The modulation transfer function (MTF) of all field rays in the telephoto system is as follows: Figure 6 As shown, the optical transfer function (OTF) reaches above 0.2 at 172 lp / mm, meeting the imaging quality requirements of the telephoto system.

[0066] In some embodiments of the present application, the camera module includes a periscope 4. The periscope 4 is disposed within the housing 1 and opposite the light aperture 11. A periscope surface 41 is formed on the periscope 4. The periscope 4 can be fixed within the housing 1 or positioned within the housing 1 via an intermediate support. The periscope 4 is either a periscope prism or a periscope reflector.

[0067] Furthermore, the camera module also includes a tilt adjustment mechanism 6, which is arranged in the outer shell 1, and the periscope 4 is connected to the tilt adjustment mechanism 6. The tilt adjustment mechanism 6 is used to drive the periscope surface 41 to rotate relative to the outer shell 1, thereby adjusting the direction of the reflected light beam of the periscope surface 41.

[0068] Specifically, taking the example of a periscope mirror surface 41 formed on a periscope reflector, the inclination adjustment mechanism 6 includes a carrier and an adjustment member, with the periscope reflector supported on the carrier's support surface. For example, the carrier is fixed to the housing 1, and the periscope reflector is connected to the support surface via the adjustment member, and the adjustment member is used to adjust the inclination of the periscope reflector relative to the support surface. Alternatively, the periscope reflector is fixed to the support surface, and the adjustment member is connected between the carrier and the housing 1, and the adjustment member is used to adjust the inclination of the support surface relative to the housing 1.

[0069] When the periscope mirror surface 41 is formed on the periscope reflector, the light transmission in the entire camera module is entirely composed of reflective lenses, and since a longer light beam transmission path is achieved through fewer lenses, the overall light transmittance of the camera module is high and the light utilization rate is strong, so that the light received by the image sensor 5 has no color difference, which is conducive to improving image quality.

[0070] The camera module provided in some embodiments of the present application further includes a circuit board 8, to which the image sensor 5 and the drive mechanism 3 are electrically connected. Specifically, the image sensor 5 is electrically connected to the circuit board 8 via gold wires. The camera module further includes an infrared filter 9, which is disposed on the light-entering side of the image sensor 5.

[0071] The image sensor 5 and the drive mechanism 3 are adapted to be communicatively connected via a controller of a terminal device. When the image received by the image sensor 5 is offset, for example due to a temperature rise, jitter, or mechanical assembly deviation of the camera module, the image sensor 5 self-detects the offset. The controller then controls the drive mechanism 3 to adjust the deflection angle of the corresponding reflector based on the offset, automatically calibrating the imaging position of the image sensor 5 and thereby adjusting the imaging quality. When the image sensor 5 self-detects that the magnification needs to be increased or decreased, the controller controls the drive mechanism 3 to drive the corresponding reflector to move, thereby increasing or decreasing the distance between the reflector and other reflectors, thereby achieving automatic optical focusing.

[0072] Furthermore, the image sensor 5 and the tilt adjustment mechanism 6 are adapted to be communicatively connected via a controller of the terminal device. When the camera module shakes, the image on the image sensor 5 shifts. The image sensor 5 self-diagnoses and determines the amount of shift. The controller then controls the tilt adjustment mechanism 6 based on this amount to adjust the tilt angle of the periscope mirror 41 relative to the housing 1, thereby achieving optical image stabilization of the camera module. This embodiment enables optical image stabilization of the camera module to be achieved simultaneously through the tilt adjustment mechanism 6 and the drive mechanism 3.

[0073] The present application also provides an electronic device, which may be a mobile phone, tablet computer, game console, laptop computer, etc. The electronic device includes a housing and a camera module, which is the camera module described in any of the above embodiments, and is disposed in the housing.

In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example.
