Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of electronics, and in particular, to a lens module, an image pickup device, and an electronic device. BACKGROUND

[0002] An image pickup device is an important part for an electronic device (such as a mobile phone, a tablet computer, a camera, a monitoring device, a drone, etc.) to obtain images. In order to be aesthetically pleasing and convenient to carry, the electronic device needs to be miniaturized, and the size of the image pickup device with the same focusing range also needs to be smaller and smaller.

[0003] In order to cover the shooting requirements of multiple focal lengths such as long distance, medium distance, and short distance at the same time, the image pickup device needs to have high zoom capability (for example, to achieve super telephoto shooting). In order to have high zoom capability, the conventional image pickup device usually needs to lengthen the optical path. However, this will occupy a lot of space, which is not conducive to realizing the small size of the image pickup device, and is also not conducive to realizing the miniaturization of the electronic device.

[0015] In one of the embodiments, the reflecting element is a pentagonal prism.

[0016] Alternatively, the first incident portion is adjacent to the second reflecting surface, and is arranged opposite to the first reflecting surface.

The light path is prolonged by forming a reflecting light path inside the reflecting element, so that the camera device has a more compact structure under the condition of having the same zooming capability, which is conducive to the miniaturization of the camera device. Furthermore, it is also conducive to reducing the volume of the electronic device using the camera device and realizing the miniaturization of the electronic device.

DETAILED DESCRIPTION

[0041] To make the objects, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the present disclosure herein is only for the purpose of describing specific embodiments and is not intended to limit the present disclosure.

[0043] For the convenience of understanding, the technical terms involved in the embodiments of the present disclosure will be explained and described below.

[0044] Optical axis, the direction of light conduction of the optical system, referring to the chief ray of the central field of view. For a symmetric transmission system, it generally coincides with the center line of rotation of the optical system.

[0045] Focal point, the convergence point of light rays parallel to the optical axis after refraction by the lens.

[0046] Focal length, also known as focal length, is a way to measure the convergence or divergence of light in an optical system, which refers to the distance from the optical center of the lens to the focal point when the infinite scene passes through the lens and forms a clear image on the focal plane. For a fixed-focus lens, the position of the optical center is fixed, so the focal length is fixed; for a zoom lens, the change of the optical center of the lens leads to the change of the focal length of the lens, so the focal length can be adjusted.

[0047] Object space, which is bounded by the lens, is the space where the object is located.

[0048] Image space, which is bounded by the lens, is the space where the image formed by the light emitted by the object passing through the lens is located.

[0049] The side of the lens where the object is located is called the object side, and the surface of the lens close to the object side can be called the object side surface. The side of the lens where the image of the object is located is called the image side, and the surface of the lens close to the image side can be called the image side surface.

[0050] Focusing, also known as focusing or focusing, is the process of changing the image distance to make the object image clear through the focusing component in the camera module. Specifically, the distance between the image sensor and the lens assembly is adjusted to make the image captured by the image sensor clear, thereby completing the focusing.

[0051] In addition, focusing includes automatic focusing and manual focusing, where automatic focusing (auto focus) is a method that uses the principle of light reflection from an object, and the reflected light is received by a photosensitive element on the camera module, and through computer processing, the driving device is driven to focus. For example, the camera module emits an infrared ray (or other ray), and according to the reflection of the object, the distance of the object is determined, and then the image distance is adjusted according to the measured result to achieve automatic focusing.

[0052] Optical image stabilization (OIS) refers to the setting of optical components in imaging instruments such as mobile phones or cameras to avoid or reduce the phenomenon of instrument shaking during the capture of optical signals, in order to improve the imaging quality. A common approach is to use a gyroscope to detect shaking, and then use an OIS motor to translate or rotate the entire lens in the opposite direction to compensate for the image blur caused by the shaking of the imaging instrument during exposure.

[0053] At present, electronic devices such as mobile phones, tablet computers, cameras, monitoring devices, and unmanned aerial vehicles occupy an increasingly important position in people's lives and bring many conveniences and pleasures to people's lives. The camera module is an important part of electronic devices to obtain images. There are many types and brands of electronic devices with image acquisition functions, which provides consumers with many choices. How to gain the favor of consumers and improve product competitiveness has become a problem that electronic device manufacturers pay more and more attention to.

[0054] In order to be aesthetically pleasing and convenient to carry, electronic devices also need to adapt to the demand for miniaturization development. In order to cover the requirements of long-distance, medium-distance and close-range shooting at the same time, the camera module needs to have a large focusing range, and the lens assembly needs to have a large stroke range. In a periscopic camera module, the movement of the lens assembly causes the distance between the lens assembly and the prism to change. In order to meet the requirements of light projection, the size of the prism assembly also needs to be increased, which in turn causes the volume of the periscopic camera module to become larger and larger, requiring a lot of internal space of the electronic device, seriously affecting the arrangement of other internal components of the electronic device and restricting the miniaturization development of the electronic device.

[0055] Based on this, the present disclosure provides a periscopic camera module. By optimizing the focusing adjustment structure, the periscopic camera module can meet the requirement of a large focusing range, and the structure of the periscopic camera module is more compact and the size is smaller, thereby being able to adapt to the miniaturization development of electronic devices.

[0056] In order to better understand the periscopic camera module of the present disclosure, the electronic device applying the periscopic camera module is described.

[0057] As shown in Figure 1 and Figure 2 In some embodiments, an electronic device 1 is provided, which includes a housing assembly 10 and a camera device 20. The camera device 20 is arranged on the housing assembly 10.

[0058] The camera device 20 includes an image sensor 100 and a lens module 200. The lens module 200 includes a main lens 210 and a reflective element 220. The main lens 210 is provided with a first optical axis 211, and the main lens 210 includes a light-in portion 212 and a light-out portion 213 arranged at intervals along the direction of the first optical axis 211. The reflective element 220 includes a first incident portion 221, a first exit portion 222, and at least two reflecting surfaces 223. The first incident portion 221 can receive light emitted from the light-out portion 213. The at least two reflecting surfaces 223 can reflect the light incident from the first incident portion 221 to the first exit portion 222, and a reflection light path 224 is formed between two of the at least two reflecting surfaces 223. The image sensor 100 is arranged at an interval from the first exit portion 222 and can receive light emitted from the first exit portion 222.

[0059] When the camera device 20 is in use, light enters through the light-inlet section 212 of the main lens 210, exits through the light-outlet section 213 to the incident section of the reflective element 220, and then exits through the exit section of the reflective element 220 to the image sensor 100. During this process, the light emitted from the main lens 210 is reflected at least twice by the at least two reflective surfaces 223 of the reflective element 220, thereby extending the optical path to the image sensor 100 and increasing the distance between the main lens 210 and the image sensor 100, effectively increasing the focal length of the camera device 20. Furthermore, by forming a reflected light path 224 inside the reflective element 220 to extend the optical path, the camera device 20 achieves a more compact structure while maintaining the same zoom capability, facilitating miniaturization. This, in turn, helps to reduce the size of the electronic device 1 using the camera device 20, achieving miniaturization of the electronic device 1.

[0060] It should be noted that the reflective element 220 can be implemented in various ways, including but not limited to a reflective prism or a reflector.

[0061] like Figure 2 As shown, in one example, at least two reflecting surfaces 223 include a first reflecting surface 2231 and a second reflecting surface 2232. The first reflecting surface 2231 can reflect light incident from the first incident portion 221 to the second reflecting surface 2232, forming a reflected light path 224. The second reflecting surface 2232 can reflect light reflected from the first reflecting surface 2231 to the first exiting portion 222. In this way, the reflective element 220 can use the first reflective surface 2231 to reflect the light incident from the first incident part 221 to the second reflective surface 2232, and then reflect the light reflected from the first reflective surface 2231 to the first exit part 222 through the second reflective surface 2232, so that the direction of the incident light and the exit light intersect. By extending the light path through the reflected light path 224, the light propagation direction is also changed, so that the image sensor 100 can be arranged non-axially along the first optical axis 211 of the main lens 210, avoiding the camera device 20 being stacked too long along the first optical axis 211, which would increase the difficulty of its arrangement in the electronic device 1.

[0062] like Figure 2As shown, in some embodiments, the first incident portion 221 is adjacent to and opposite to the second reflecting surface 2232, and the first exiting portion 222 is adjacent to and opposite to the first reflecting surface 2231. A fifth optical axis 225 is provided between the second reflecting surface 2232 and the first exiting portion 222, and this fifth optical axis 225 intersects with the first optical axis 211. Thus, the proximity of the first incident portion 221 to the second reflecting surface 2232 shortens the distance to the second reflecting surface 2232, making the structure of the reflecting element 220 more compact. Furthermore, the opposite arrangement of the first reflecting surface 2231 and the second reflecting surface 2232 effectively extends the reflected light path 224, thereby extending the light path from the main lens 210 to the image sensor 100 and improving the zoom performance of the imaging device 20.

[0063] Furthermore, by intersecting the fifth optical axis 225 with the first optical axis 211, the image sensor 100 is positioned on the axis of the fifth optical axis 225, achieving a non-axial arrangement along the first optical axis 211 of the main lens 210.

[0064] Optionally, such as Figure 2 As shown, in some embodiments, the reflective element 220 is a pentaprism. Thus, using a pentaprism to form the first reflective surface 2231 and the second reflective surface 2232 results in a compact structure, which helps to reduce the size of the lens module 200.

[0065] In combination with any of the above embodiments of the first reflecting surface 2231 and the second reflecting surface 2232, such as Figure 3 As shown, in some embodiments, the lens module 200 further includes a first optical element 230, which includes a second incident portion 231 capable of receiving external light from the lens module 200 and a second exiting portion 232 capable of receiving light incident from the second incident portion 231. The light-receiving portion 212 can receive light emitted from the second exiting portion 232. Thus, the first optical element 230 can guide external light from the electronic device 1 into the light-receiving portion 212.

[0066] It should be noted that the specific implementation of the first optical element 230 includes, but is not limited to, a planar lens (such as...). Figure 3 As shown), polygonal prism (such as...) Figure 4 (as shown) etc.

[0067] like Figure 4As shown, in some embodiments, the first optical element 230 includes a third reflective surface 233 disposed between the second incident portion 231 and the second exit portion 232. The third reflective surface 233 can reflect light incident from the second incident portion 231 to the second exit portion 232. Thus, by utilizing the third reflective surface 233, the second incident portion 231 and the second exit portion 232 are not spaced apart along the axial direction of the first optical axis 211. Light rays not aligned with the first optical axis 211 can pass through the second incident portion 231 to the third reflective surface 233, and then be reflected by the third reflective surface 233 to the light-receiving portion 212 of the main lens 210. This allows for more flexible arrangement of the main lens 210.

[0068] like Figure 4 As shown, in some embodiments, the first optical element 230 is disposed in front of the light-entry portion 212, so that a second optical axis 201 is formed between the second emitting portion 232 and the light-entry portion 212, which is aligned with the first optical axis 211. The reflective element 220 is disposed behind the light-exiting portion 213, so that a third optical axis 202 is formed between the first incident portion 221 and the light-exiting portion 213, which is aligned with the first optical axis 211. In this way, the second emitting portion 232, the light-entry portion 212, the light-exiting portion 213, and the first incident portion 221 are spaced apart along the axial direction of the first optical axis 211, which facilitates the propagation of light along the axial direction of the first optical axis 211 when adjusting the distance between the main lens 210 and the first optical element 230 and the reflective element 220, thus helping to ensure the imaging performance of the imaging device 20.

[0069] like Figure 4 As shown, in some embodiments, a fourth optical axis 234 is provided between the second incident portion 231 and the third reflecting surface 233. A fifth optical axis 225 is provided between the second reflecting surface 2232 and the first exit portion 222. The fourth optical axis 234 and the fifth optical axis 225 are arranged in the same direction and are perpendicular to the first optical axis 211. In this way, the first optical element 230 can guide the light in the radial direction of the first optical axis 211 to the main lens 210, and transmit the light to the image sensor 100 arranged in the radial direction of the first optical axis 211 through the reflecting element 220. That is, the second incident portion 231 and the image sensor 100 are spaced apart along the axial direction of the first optical axis 211 and also spaced apart along the radial direction of the first optical axis 211, avoiding the image sensor 100 and the second incident portion 231 from being stacked too long along the direction of the first optical axis 211, which would cause the imaging device 20 to occupy too much axial space of the first optical axis 211 and increase the difficulty of its arrangement in the electronic device 1.

[0070] When the electronic device 1 is a mobile phone or a tablet computer, the first optical axis 211 can be arranged along the length direction or the width direction of the electronic device 1, and the first optical member 230 can be used to guide the light in the thickness direction of the electronic device 1 into the main lens 210, and then the light is reflected by the reflecting element 220 to the image sensor 100 arranged along the thickness direction of the electronic device 1. In this way, the thinness of the electronic device 1 can be achieved.

[0071] Optionally, the lens module 200 is a periscopic lens module 200.

[0072] As shown in Figure 4 some embodiments, the housing assembly 10 includes a back cover 10a, and the first optical member 230 is arranged on the back cover 10a and forms a light transmission area on the back cover 10a. The incidence direction of the second incidence part 231 and the emission direction of the first emission part 222 are arranged in the same direction as the thickness direction of the back cover 10a. In this way, the image sensor 100 and the second incidence part 231 are arranged in the thickness direction of the back cover 10a, and the main lens 210 is arranged in the width direction or the length direction of the back cover 10a, which can effectively reduce the thickness space occupied by the camera 20 in the electronic device 1, and can easily meet the thin design of the electronic device 1 while improving the zoom performance of the camera 20.

[0073] Referring to Figure 4 the drawings, the thickness direction of the back cover 10a is the Z-axis direction, and the length direction or the width direction of the back cover 10a is the X-axis direction. The first optical axis 211 is arranged in the same direction as the X-axis, and the fourth optical axis 234 and the fifth optical axis 225 are arranged in the same direction as the X-axis.

[0074] Optionally, when the electronic device 1 is a mobile phone or a tablet computer, the first optical member 230 is arranged on the back cover 10a, and the camera 20 is a rear camera. At this time, the thickness direction of the electronic device is the Z-axis direction, and the length direction or the width direction of the electronic device is the X-axis direction.

[0075] As shown in Figure 4 some embodiments, the first optical member 230 is a triangular prism, and the reflecting element 220 is a pentagonal prism. The incidence direction of the second incidence part 231 and the emission direction of the first emission part 222 are arranged in the same direction and intersect the first optical axis 211, respectively. In this way, the structure of the lens module 200 is more compact, which is beneficial to reduce the volume of the camera 20 and achieve the miniaturization and thinness of the electronic device 1.

[0076] As shown in Figures 5 to 7As shown, in some embodiments, the lens module 200 further comprises a bearing assembly 240 and a driving assembly 250 disposed on the bearing assembly 240. The reflecting element 220 is fixedly connected with the bearing assembly 240. The main lens 210 is slidingly connected with the bearing assembly 240, and the driving assembly 250 is configured to drive the main lens 210 to reciprocate along the first optical axis 211. In this way, by driving the main lens 210 to reciprocate along the first optical axis 211 by the driving assembly 250, the optical path length between the image sensor 100 and the lens assembly is adjusted to make the image captured by the image sensor 100 clear, thereby completing the focusing.

[0077] It should be noted that the specific implementation of the optical anti-shake assembly 260 can be realized by various conventional technologies, which can meet the design requirements of the present application.

[0078] Optionally, as shown in Figure 6 and Figure 7 in an example, the driving assembly 250 comprises a first magnet 251 fixedly arranged on the main lens 210 and a driving coil 252 drivingly matched with the first magnet 251. The driving coil 252 is arranged on the bearing assembly 240 and matched with the first magnet 251 to drive the main lens 210 to reciprocate along the axial direction of the first optical axis 211, thereby realizing the focusing.

[0079] Further, as shown in Figure 6 and Figure 7 in some embodiments, the lens module 200 further comprises a first optical element 230 movably connected with the bearing assembly 240. In the direction of the first optical axis 211, the second incident part 231 is arranged in front of the light inlet part 212, and the first optical element 230 is movably connected with the bearing assembly 240. The lens module 200 further comprises an optical anti-shake assembly 260 arranged on the bearing assembly 240, and the first optical element 230 is drivingly matched with the optical anti-shake assembly 260. In this way, by drivingly matching the optical anti-shake assembly 260 with the first optical element 230, the anti-shake function of the camera 20 can be realized to avoid or reduce the instrument shaking phenomenon in the process of capturing the optical signal, thereby improving the imaging quality.

[0080] It should be noted that the specific implementation of the optical anti-shake assembly 260 can be realized by various conventional technologies, which can meet the design requirements of the present application.
