Description
Technical Field
The invention relates to the technical field of camera modules, in particular to a periscope type camera module solution and corresponding electronic equipment.
Background
Recently, as mobile communication technology has been developed and widespread such as smart phones, miniaturized and lightweight camera modules have appeared, at least one or more camera modules have been disposed on a portable terminal body. The design requirements of customers on camera modules are increasing, users not only require that camera modules configured on mobile terminals have high capacity and high performance, but also require that camera modules meeting digital cameras (DSLR) standards be developed, and the development of camera modules is required to meet the development trend of miniaturization and portability while maintaining high performance and high capacity.
The periscope type camera shooting module is used for reflecting light beams incident to the front end of the camera shooting module through a mode of arranging a reflecting prism at the front end, so that the direction of the light beams is changed, the light beams reach a photosensitive chip after passing through a lens assembly and a color filter, the camera shooting module is transversely arranged in electronic equipment, and the long-focus camera shooting module is further guaranteed to reduce the height of the long-focus camera shooting module when the long-focus camera shooting effect is met. Therefore, the periscope type camera shooting module can achieve the requirements of miniaturization and optical zooming of terminal equipment to a great extent, the longer lens structure is reasonably changed through changing the angle of incident light, and the height of the module is reduced.
The camera module realizes an optical automatic focusing function (hereinafter referred to as focusing or zooming function, auto Focus), a zooming function and an optical anti-shake function (hereinafter referred to as anti-shake function, optical Image Stabilization, optical image stabilization) in the shooting process through a motor. The focusing or zooming function refers to a function of linearly moving a lens system in an optical axis direction by a motor to adjust a focus, focusing an object to generate a clear image at an image sensor (CMOS, CCD, or the like) located at the rear of the lens. The anti-shake function is a technique of compensating for image blur by motor anti-shake control when shake occurs in photographing, and an image sensor picks up an image of light incident through a lens system and converts the image into an image signal.
The driving structure of the camera module becomes more complex due to the increase of focusing or zooming functions, zooming functions and anti-shake functions. In addition, the camera module needs to be equipped with a corresponding actuator, which on the one hand results in an increased size of the camera module and a limited installation space reserved for the camera module, and on the other hand, the increase of the driving structure increases the weight of the lens and other components, so that a larger driving force is required for implementation, which increases the energy consumption for driving the module.

The light diverting assembly 20 is disposed in front of the lens assembly 30 or on the light incident side of the lens assembly 30, and the light diverting assembly 20 is used to change the path of the incident light, and in some alternative embodiments, it is reflected by a prism or a reflecting mirror, so as to turn the light path. The lens assembly 30 is disposed on the photosensitive path of the photosensitive assembly 40, and the light turning assembly 20 is used to change the propagation direction of the incident light entering the light turning assembly 20, so that the turned light passes through the optical path of the lens assembly 30, and the light is received by the photosensitive assembly 40 for imaging after the light path of the lens assembly 20 is corrected.
The housing 10 has a hollow cavity for accommodating the light redirecting component 20, the lens component 30 and the photosensitive component 40. The housing 10 further includes a base 11 and a cover 12. In the housing 10, the light diverting assembly 20 is disposed on the light incident side of the lens assembly 30, and the photosensitive assembly 40 is disposed on the light emergent side of the lens assembly 30. In other words, the light diverting assembly 20, the lens assembly 30, and the photosensitive assembly 40 are disposed in this order from one side of the housing 10 to the other side of the housing along the optical axis direction of the lens assembly, i.e., the length direction of the housing. In some alternative embodiments, the housing 10 is an integrally formed structure including an integrally formed base 11 extending along a length to provide a better mounting reference for the light redirecting assembly 20, lens assembly 30, and photosensitive assembly 40.
Referring to fig. 1 and 6, the susceptor 11 includes an opening 111 at an upper side, a susceptor side wall 112 surrounding the periphery, and a susceptor bottom surface 113. The cover 12 is disposed in the opening 111 of the base 11, and the base sidewall 112, the base bottom 113 and the cover 12 of the base 11 together form an inner space of the housing 10.

Light steering assembly mounting area 114 lens assembly mounting area 115 photosensitive assembly mounting area 116
The base 11 may be integrally formed, i.e. the base bottom 113 is integrally formed, and the base sidewall 112 is integrally formed with the base bottom 113 in an upward extending manner, such that the light steering assembly 20, the lens assembly 30 and the photosensitive assembly 40 are disposed in the inner space of the housing 10. In some alternative embodiments, the base 11 may be formed by connecting separate base portions provided with one or more of the light redirecting element 20, the lens element 30, and the photosensitive element 40, respectively, to each other.
In some alternative embodiments, the base side wall 112 is provided with a first protruding wall 1121 and a second protruding wall 1122, the first protruding wall 1121 and the second protruding wall 1122 dividing the interior space of the housing into the light redirecting component mounting area 114, the lens component mounting area 115, and the photosensitive component mounting area 116. Wherein the first protruding wall 1121 separates the light redirecting member mounting region 114 from the lens member mounting region 115, i.e., the light redirecting member 20 is disposed on one side of the first protruding wall 1121 and the lens assembly 30 is disposed on the other side of the first protruding wall 1121. The second protruding wall 1122 separates the lens assembly mounting area 115 and the photosensitive assembly mounting area 116, i.e., the lens assembly 30 is disposed on one side of the second protruding wall 1122 and the photosensitive assembly 40 is disposed on the other side of the second protruding wall 1122. Wherein the first protruding wall 1121 and the second protruding wall 1122 may be formed extending inward from the base side wall 112.
Referring to fig. 1, the cover 12 includes a cover body 121 and an opening 122 through which incident light enters, the cover body 121 covers the opening 111 of the base 11, and the opening 122 is disposed above the light-turning assembly 20. Incident light enters through the opening 122, is redirected by the light redirecting assembly 20, passes through the lens assembly 30, and reaches the photosensitive assembly 40 for imaging. The cover plate 12 may be integrally formed to cover the opening 111 of the base 11, or may be formed of separate members respectively covering the light-redirecting member mounting area 114, the lens assembly mounting area 115, and the photosensitive member mounting area 116.
Referring to fig. 2, the housing 10 of the camera module 1 may further include a spacer 13, which is an elastic member, disposed between the base 11 and the cover 12, and fills a structural gap between the base 11 and the cover 12, so that the base 11 and the cover 12 are tightly fixed.
For ease of understanding, in this application, this is illustrated by establishing a spatial coordinate system. The direction of the optical axis of the lens is defined as a Z-axis direction, a first preset direction perpendicular to the plane of the optical axis is defined as an X-axis direction, and a second preset direction perpendicular to the plane of the optical axis is defined as a Y-axis direction. In this embodiment, the direction of the incident light is defined as an X-axis direction, the X-axis direction and the Y-axis direction are perpendicular to each other, and the Z-axis direction is perpendicular to a plane in which the X-axis direction and the Y-axis direction are located, in other words, the X-axis, the Y-axis, and the Z-axis form a three-dimensional rectangular coordinate system.
The camera module 1 may have at least one of a focusing or zooming function, a zooming function, and an optical anti-shake function. In order to realize functions such as focusing or zooming, and optical anti-shake, the camera module 1 needs to be equipped with corresponding actuators, which leads to an increase in the size of the camera module, and the installation space reserved for the camera module is limited.
For this purpose, a camera module 1 is provided, in which different functions are implemented by different functional components. The camera module 1 includes a first driving portion 24 and a second driving portion 33, wherein the first driving portion 24 is disposed on the light steering assembly 20 for driving the reflective member 23 to perform anti-shake, and the second driving portion 33 is disposed on the lens assembly 30 for driving the lens portion 31 to perform focusing or zooming. The light steering assembly 20 performs an optical anti-shake function, and the lens assembly 40 performs a focusing or zooming function to be installed in an inner space of a predetermined housing 10, thereby satisfying miniaturization requirements while performing anti-shake and focusing or zooming.
The light diverting assembly 20 changes the path of the light incident through the opening 111 by the first driving part 24 to implement an optical anti-shake function. When capturing an image or a moving image, the image may be blurred or the moving image may shake due to hand shake or other shake of the user. A relative displacement corresponding to the shake is supplied to the first driving section 24, and the first driving section 24 drives the reflecting member 23 to correct the shake of the hand or other shake of the user. .
The anti-shake function is achieved by the movement of the first driving part 24 having a relatively low weight since it does not include a lens or the like, and thus, power consumption can be significantly reduced. That is, in order to realize the anti-shake function, light on which anti-shake is performed is directed to be incident on the lens assembly 40 by changing the movement direction of the light by the movement of the first driving part 24 on which the reflection member 23 is disposed, without moving the lens assembly 30 or the photosensitive assembly 40.
The light is received by the photosensitive assembly 40 through the lens assembly 30 to form an image, and the lens assembly 30 realizes a focusing function. When capturing an image, the lens assembly 30 adjusts the distance between the lens portion 31 and the photosensitive assembly 40 by moving the second driving portion 33 provided with the lens portion 31, thereby realizing clear imaging. In some alternative embodiments, only the focusing or zooming function is realized by the lens assembly 30, the anti-shake function and the zooming function are not performed, and the structural components are reduced, so that the height dimension of the lens assembly 30 can be reduced. Of course, the lens assembly 30 may also perform anti-shake functions other than focusing or zooming functions and zooming functions to meet different shooting scene requirements. Referring to fig. 2-8, the light redirecting assembly 20 in accordance with an embodiment of the present application is illustrated. In this application, the light redirecting assembly 20 is disposed in the light redirecting assembly mounting area 114 of the base 11, the light redirecting assembly 20 comprising a first support mechanism 21 disposed in the base 11 and supported by the base bottom surface 113, a second support mechanism 22 mounted on the first support mechanism 21, a reflective member 23 mounted on the second support mechanism 22, and a first drive portion 24 that provides drive to the reflective member 23.

As shown in fig. 5C, the reflecting member 23 makes the light beam realize turning in 90 ° direction, the reflecting member 23 may be a prism, and includes two right angle surfaces 231 and 232 and a reflecting surface 233, wherein the reflecting surface 233 is an inclined surface, each right angle surface 231 and 232 forms a 45 ° angle with the reflecting surface 233, a first light path 201 and a second light path 202 perpendicular to each other are formed on the reflecting surface 233, wherein the first light path 201 is parallel to the incident light direction, the second light path 202 is parallel to the optical axis direction of the lens assembly 30, the lens assembly 30 and the photosensitive assembly 40 are sequentially disposed on the second light path 202, i.e. the first light path 201 is parallel to the X axis direction, the second light path 202 is parallel to the Z axis direction, the right angle surface 231 is an incident surface, the right angle surface 232 is an emergent surface, the incident light beam enters along the first light path 201 by the right angle surface 231, the incident light beam is reflected by the reflecting surface 233 to change the light path, passes through the right angle surface 232, exits the reflecting member 23, passes through the lens assembly 30, and reaches the photosensitive assembly 40.
The reflecting member 23 is fixedly provided on the second supporting mechanism 22. The second support mechanism 22 includes a mounting surface 221, and the mounting surface 221 may be an inclined surface, which is adapted to the reflecting surface 233 of the reflecting member 23, so that the reflecting member 23 is stably fixed to the second support mechanism 22.

By the structure in which the single-sided third holding member shares the groove, the structure of the lens carrier 32 is simplified, the weight of the lens carrier 32 is reduced, the power consumption is reduced, and at the same time, the focusing stroke distance of the lens carrier 32 and the lens portion 31 is increased.
In an embodiment of the present application, the third holding element 341 is a spherical member, the base 11 fixes the lower half of the third holding element 341 with a hemispherical recess matching the third holding element 341, the lens carrier 32 fixes the upper half of the third holding element 341 with a groove-shaped recess for guiding the lens carrier 32 and the lens part 31 supported thereby and the like to move in the optical axis direction (Z axis) under the driving action of the third driving assembly 331.

The lens carrier 32 is pressed toward the base bottom surface 113 so that the third holding member 341 maintains a contact state with the lens carrier 32 and the base bottom surface 113. In the YZ plane direction (horizontal direction), the focusing or zooming magnet assembly 36 is offset from the third driving magnet 3312 and offset from the third holding element 341.

Wherein the magnetic conductive sheet 35 may be molded in the lens carrier 32 by integral molding.
It should be noted that, in the present application, the focusing or zooming magnetic assembly 36 indirectly generates an attractive force with the third driving magnet 3312 to clamp the third holding element 341, by providing an additional magnetic sheet 35, and by magnetizing the third holding element 341 and the fifth groove 322 of the lens carrier 32 and the fifth groove 1153 of the base bottom 113, a sufficient space is avoided for the third holding element 341 and the sixth groove 322 of the lens carrier 32, and the fifth groove 1153 of the base bottom 113, instead of the original focusing or zooming magnetic assembly 36 being directly arranged on the base bottom 113 opposite to the third driving magnet 3312, such that the arrangement position of the third holding element 341 and the fifth groove 1153 of the base bottom 113 is limited by the arrangement of the focusing or zooming magnetic assembly 36, and in addition, the clamping force of the original focusing or zooming magnetic assembly 36 and the third driving magnet 3312 is limited by the height distance of the third holding element 341, and the distance between the magnetic sheet 35 and the focusing or zooming magnetic assembly 36 is close enough to provide a sufficient clamping force for the third holding element 341.
