Description

Camera module and electronic device

Technical Field

The application relates to the technical field of electronics, concretely relates to camera module and electronic device.

Background

In the related art, as the number of pixels increases, the target surface of the sensor of the camera becomes larger. When the target surface of the sensor is continuously enlarged, the focal length of the lens matched with the target surface is continuously enlarged under the condition that the angle of field is basically unchanged, and when the focal length of the lens is increased, the total length of the lens is correspondingly increased. This makes the body of an electronic device such as a cellular phone thicker and thicker. Secondly, as the aperture and resolution indexes are improved, the lens must use more lenses to achieve the indexes, however, the increase of the lenses increases the assembly complexity and reduces the product assembly yield.

The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

Referring to fig. 4 and 5, the fixed-focus lens 23 corresponding to the image sensor 22 includes a first lens barrel 231, a second lens barrel 232, a first lens group 233 and a second lens group 234.

Of course, in some embodiments, the second barrel 232 is also located outside the first barrel 231, and the second barrel 232 and the first barrel 231 are slidably connected to the housing 21 respectively.

It should be noted that in the description of the present application, for example, in the above description of the "first lens group" and the "second lens group", the terms "first" and "second" are used for descriptive purposes only and do not indicate that the fixed focus lens has only two lens groups, nor does it imply that the first lens group is more important than the second lens group, or that the terms "first" and "second" are not to be interpreted as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. Further, in the description of the present application, it is to be understood that the terms "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

In such embodiments, in addition to first lens group 233 and second lens group 234 being movable along optical axis L, other lens groups may be movable along optical axis L or partially movable along optical axis L or neither, and are not limited herein.

Referring to fig. 4 to 7, in the present embodiment, the first lens group 233 and the second lens group 234 can move along the optical axis L to a side away from the image sensor 22 to move the fixed focus lens 23 from the first position a to the second position B (from the positions shown in fig. 4 and 6 to the positions shown in fig. 5 and 7), the length of the fixed focus lens 23 in the second position B is greater than that of the fixed focus lens 23 in the first position a, the fixed focus lens 23 is housed in the housing 10 of the electronic device 100 when the fixed focus lens 23 is in the first position a, the fixed focus lens 23 at least partially extends out of the housing 10 when the fixed focus lens 23 is in the second position B, the first lens barrel 231 and the second lens barrel 232 can both be driven by the driving assembly 30, that is, in the embodiment of the present application, the driving assembly 30 connects the first lens group 233 and the second lens group 234, and the driving assembly 30 is used for driving the first lens group 233 and the second lens group 234 to move the fixed focus lens 23 between the first position a and the second position B.

Specifically, referring to fig. 4 and 6, when the fixed-focus lens 23 is in the first position a, the first lens group 233 of the fixed-focus lens 23 is close to the image sensor 22, the second lens group 234 is close to the first lens group 233, the space between the first lens group 233 and the image sensor 22 is smaller, and the space between the second lens group 234 and the first lens group 233 is also smaller. At this time, the first lens group 233, the first lens barrel 231, the second lens group 234 and the second lens barrel 232 are all located in the housing 21 of the image capturing assembly, or the first lens group 233, the first lens barrel 231, the second lens group 234 and the second lens barrel 232 are all located in the housing 10 of the electronic device 100 (as shown in fig. 2). In this case, since the distance between the first lens group 233 and the image sensor 22 is small, the distance between the second lens group 234 and the first lens group 233 is small, and the total length of the fixed focus lens 23 and the image pickup module 20 is short.

In this way, compared to the technical solution of increasing the total length of the lens to increase the pixels and the resolution, and making the body of the electronic device thicker, in the present application, the camera module 20 is installed in the housing 10 of the electronic device 100 in the state when the fixed-focus lens 23 is at the first position a, which can avoid increasing the thickness of the housing 10, and is beneficial to the light and thin of the electronic device 100. When shooting is needed, the first lens group 233 and the second lens group 234 only need to be driven to move, so that the fixed-focus lens 23 extends out of the housing 10 of the electronic device 100 to move to the second position B, so that the camera module 20 focuses on the image sensor 22, and a normal camera function can be achieved.

In addition, in the embodiment of the present application, the first lens group 233 and the second lens group 234 are packaged separately, so that compared with the technical solution of packaging more lenses together for increasing the pixels and the resolution, the multistage lens group of the present application can be packaged separately to reduce the number of lenses 235 that each lens group needs to be packaged, thereby reducing the assembly difficulty of the lens and improving the assembly yield of the lens.

It is understood that, in the embodiment of the present application, when the fixed-focus lens 23 is in the first position a, the camera module 20 is focused outside the image sensor 22. That is, when the fixed focus lens 23 is at the first position a, the image sensor 22 cannot normally form an image, and the image pickup module 20 cannot perform a normal image pickup function. The "camera module 20 is focused outside the image sensor 22" may be understood that the image captured by the image sensor 22 is not the clearest object image, and the plane of the clearest object image is located outside the plane of the image sensor 22.

When it is required to use the image capturing module 20 for normal shooting, the first lens group 233 and the second lens group 234 can be driven by the driving assembly 30 to move along the optical axis L to a side away from the image sensor 22 so as to move the fixed-focus lens 23 from the first position a to the second position B. when the fixed-focus lens 23 is in the second position B, the image capturing module 20 is focused on the image sensor 22 so as to enable the image sensor 22 to capture a sharp image, that is, in the present embodiment, the first position a can be understood as a position where the fixed-focus lens 23 is located when the first lens group 233 and the second lens group 234 move to a side where the image sensor 22 is located to an extreme position, at which the length of the fixed-focus lens 23 is shortest (as shown in fig. 4). it can be understood that, in this document, the "image capturing module 20 is focused on the image sensor 22" can be understood as a sharpest object image capture when the first lens group 20 is located at a side away from the optical axis L. when the second lens group 20 is located at a side away from the image sensor 22, the second lens group B can be understood as a lens group located at a position where the image sensor 22 is located when the first lens group 23 is located at a, or when the first lens group is located at a position B, the first lens group 23 is located at a, which is at a position B.

Referring to fig. 4 to 7, during the movement of the fixed-focus lens 23 from the first position a to the second position B, the distance between the first lens group 233 and the image sensor 22 gradually increases. The distance between the second lens group 234 and the first lens group 233 is gradually increased. That is, in such an embodiment, during the movement of the fixed focus lens 23 from the first position a to the second position B, the first lens group 233 gradually moves away from the image sensor 22, and the second lens group 234 gradually moves away from the first lens group 233.

In the embodiment shown in fig. 5, when fixed focus lens 23 is in second position B, first lens group 233 is accommodated in housing 10, and second lens group 234 extends at least partially out of housing 10. That is, when the electronic device 100 is assembled, the fixed-focus lens 23 of the camera module 20 is in the first position a, the camera module 20 is installed in the housing 10 of the electronic device 100, and the first lens group 233 and the second lens group 234 are completely accommodated in the housing 10. When the camera module 20 is required to shoot, the first lens group 233 and the second lens group 234 can be driven by the driving assembly 30 to move, so that the first lens group 233 at least partially extends out of the housing 10 of the electronic device 100. It is understood that in some embodiments, when fixed focus lens 23 is in second position B, both first lens group 233 and second lens group 234 may extend out of housing 10, that is, both first lens group 233 and second lens group 234 may extend out of housing 10 completely or second lens group 234 may extend out of housing 10 completely, and first lens group 233 partially extends out of housing 10, which is not limited herein.

Referring to fig. 8, in the present embodiment, the driving assembly 30 is connected to the first lens group 233 and the second lens group 234, the driving assembly 30 is configured to drive the first lens group 233 and the second lens group 234 to move so as to move the fixed focus lens 23 from the first position a to the second position b. specifically, the driving assembly 30 may include a first driving mechanism 31 and a second driving mechanism 32, the first driving mechanism 31 is connected to the first lens group 233, the first driving mechanism 31 is configured to drive the first lens group 233 to move along the optical axis L, the second driving mechanism 32 is connected to the second lens group 234, and the second driving mechanism 32 is configured to drive the second lens group 234 to move along the optical axis L.

In the embodiments of the present application, each of the first driving mechanism 31 and the second driving mechanism 32 may include a motor and a rack-and-pinion transmission structure, a rack may be fixedly connected to the first lens barrel 231 and the second lens barrel 232 along the direction of the optical axis L, a motor shaft of the motor is connected to a gear or a gear set, and the gear or the gear set is engaged with the rack.

In addition, in some embodiments, the first driving mechanism 31 and the second driving mechanism 32 may also be an electromagnetic driving mechanism, a piezoelectric driving mechanism, or a memory alloy driving mechanism.

Specifically, the electromagnetic driving mechanism includes a magnetic field and a conductor, if the magnetic field moves relative to the conductor, an induced current is generated in the conductor, the induced current causes the conductor to receive an ampere force, and the ampere force causes the conductor to move, where the conductor drives the first lens group 233 and the second lens group 234 to move in the electromagnetic driving mechanism. The piezoelectric driving mechanism is based on the inverse piezoelectric effect of the piezoelectric ceramic material: if voltage is applied to the piezoelectric material, mechanical stress is generated, namely, the electric energy and the mechanical energy are converted, and the rotation or linear motion is generated by controlling the mechanical deformation of the piezoelectric material, so that the piezoelectric material has the advantages of simple structure and low speed.

The driving of the memory alloy driving mechanism is based on the characteristics of the shape memory alloy: the shape memory alloy is a special alloy which, once it has memorized any shape, even if deformed, can recover to the shape before deformation when heated to a certain proper temperature, thereby achieving the purpose of driving, and has the characteristics of rapid displacement and free direction.

It is to be understood that, in the embodiment of the present application, the driving manners of the first driving mechanism 31 and the second driving mechanism 32 may be the same or different, and are not limited herein.

Next, the operation principle of the image pickup module 20 and the electronic apparatus 100 according to the present embodiment will be described.

As can be seen from fig. 2 to 5, in the electronic device 100 according to the embodiment of the present disclosure, when the fixed-focus lens 23 of the camera module 20 is located at the first position a, the total length of the fixed-focus lens 23 is the shortest, and the total length of the camera module 20 is also the shortest, so that when the camera module 20 is mounted on the housing 10, the thickness of the housing 10 is not increased due to the excessive number of the lenses 235 of the fixed-focus lens 23. In such a case, the camera module 20 is substantially completely accommodated in the housing 10 of the electronic device 100 (as shown in fig. 2), but the camera module 20 is focused on the outside of the image sensor 22, and the camera module 20 cannot normally perform a shooting operation.

When normal shooting is required, the first lens group 233 and the second lens group 234 of the fixed-focus lens 23 can be respectively driven by the driving assembly 30 to move along the optical axis L to the side away from the image sensor 22 so as to move the fixed-focus lens 23 from the first position a to the second position B (shown in fig. 5), that is, to make the second lens group 234 at least partially protrude out of the housing 10 of the electronic device 100 (shown in fig. 3), so that the camera module 20 can focus on the image sensor 22 to realize normal shooting.

In summary, the camera module 20 according to the embodiment of the present invention includes the image sensor 22 and the fixed focus lens 23, the fixed focus lens 23 is disposed corresponding to the image sensor 22, the fixed focus lens 23 includes the first lens group 233 and the second lens group 234 which are disposed at an interval along the optical axis L of the fixed focus lens 23 and can move relatively along the optical axis L, the first lens group 233 and the second lens group 234 can both move along the optical axis L to the side far away from the image sensor 22 so that the fixed focus lens 23 moves from the first position a to the second position B, when the fixed focus lens 23 is located at the first position a, the camera module 20 focuses outside the image sensor 22, and when the fixed focus lens 23 is located at the second position B, the camera module 20 focuses on the image sensor 22.

In addition, the electronic device 100 according to the embodiment of the present application includes a housing 10 and an image pickup module 20, the image pickup module 20 is mounted in the housing 10, the fixed focus lens 23 is accommodated in the housing 10 when the fixed focus lens 23 is in the first position a, and the fixed focus lens 23 is at least partially extended out of the housing 10 when the fixed focus lens 23 is in the second position B.

To sum up, in the camera module 20 and the electronic device 100 according to the embodiment of the present invention, when the fixed-focus lens 23 is located at the first position a, the interval between the image sensor 22 and the fixed-focus lens 23 is short, the total length of the whole camera module 20 is short, the camera module 20 focuses outside the image sensor 22, the camera module 20 is in a non-working state, and when it needs to work, the first lens group 233 and the second lens group 234 move relative to the image sensor 22 to move the fixed-focus lens 23 from the first position a to the second position B, so that the camera module 20 focuses on the image sensor 22, and the camera module 20 can shoot normally. Thus, the camera module 20 can be packaged into the electronic device 100 such as a mobile phone with a shorter overall length when being located at the first position a, without increasing the thickness of the electronic device 100 such as a mobile phone, which is beneficial to the light and thin of the electronic device 100. When shooting is needed, the normal shooting function can be realized only by driving the first lens group 233 and the second lens group 234 to move, so that the fixed-focus lens 23 extends out of the housing 10 of the electronic device 100 to move to the second position B. In addition, the fixed focus lens 23 is formed by combining a plurality of lens groups, so that each lens group is packaged independently, the number of lenses 235 required to be packaged by each lens group is reduced, the assembly difficulty of the lens is reduced, and the assembly yield of the lens is improved.
