Description

Technical Field

[0001] The present invention relates to the field of optical imaging, and in particular to a zoom lens unit and a manufacturing method thereof, and applications of the zoom lens unit. Background Art

[0002] The optical lens used for the light path is a component of the camera module, which is composed of a lens barrel and a lens arranged in the lens barrel. The lens of the existing optical lens (such as a glass lens or a resin lens) has a light-entering surface and a light-emitting surface, and the surface shape of the light-entering surface and the surface shape of the light-emitting surface of the lens are determined so that the light path of the optical lens is determined. Therefore, if the camera module is to be zoomed, it can only be achieved by changing the relative position of the optical lens and the photosensitive chip of the camera module. Therefore, the camera module with zoom capability also needs to provide a zoom motor, and the optical lens is drivably installed inside the zoom motor. In this way, the zoom motor adjusts the position of the optical lens relative to the photosensitive chip by driving the optical lens to move along the optical axis of the camera module to achieve the zoom of the camera module.

[0003] However, the structure of existing camera modules is increasingly not adapted to the needs of electronic devices that pursue thinness and lightness. The specific reasons are as follows: first, the camera module needs to reserve travel space for the optical lens to move along the optical axis, which makes it impossible to reduce the height of the camera module; second, the camera module needs to be equipped with zoom motors around the optical lens, which makes it impossible to reduce the length and width of the camera module corresponding to the optical lens.

[0004] Furthermore, because the camera module has to arrange zoom motors around the optical lens, resulting in a larger length and width at the position corresponding to the optical lens, the camera module with zoom capability is not suitable for being applied to the front side of a camera module that pursues a high screen-to-body ratio to form a front camera module. Summary of the invention

[0006] One object of the present invention is to provide a zoom lens unit, a manufacturing method thereof, and an application of the zoom lens unit, wherein the zoom lens unit allows zooming without changing the distance between the optical lens and the photosensitive chip of the camera module, so that the camera module does not need to be provided with a zoom motor for driving the optical lens and can effectively reduce the length and width of the camera module corresponding to the optical lens.

[0071] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0072] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0073] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0074] With reference to the accompanying drawings of the present invention Figures 1A to 1H A zoom lens unit 10 according to a preferred embodiment of the present invention and a method for manufacturing the zoom lens unit 10 will be disclosed and explained in the following description.

[0075] Reference Figure 1A The manufacturing method includes the steps of: (A) providing a flexible first driving medium 11a, wherein the first driving medium 11a has an intermediate outer side 111, an intermediate inner side 112 and an intermediate through hole 113, the intermediate outer side 111 and the intermediate inner side 112 correspond to each other, and the intermediate inner side 112 defines the intermediate through hole 113, so that the first driving medium 11a is ring-shaped.

[0076] The first driving medium 11a is bendable and deformable. Specifically, when force is applied to the first driving medium 11a, the outer side 111 and the inner side 112 of the first driving medium 11a may have a height difference, and the height difference between the outer side 111 and the inner side 112 is determined by the driving force applied to the first driving medium 11a. More specifically, the external force applied to the first driving medium 11a can ensure that the height position of the outer side 111 of the first driving medium 11a remains unchanged while only driving the inner side 112 of the first driving medium 11a to move upward or downward, so that the outer side 111 and the inner side 112 of the first driving medium 11a have a height difference and allow the first driving medium 11a to bend and deform.

[0077] For example, the initial state of the first driving medium 11a is that the outer side 111 and the inner side 112 are at the same height position. When a force is applied to the first driving medium 11a so that the height position of the outer side 111 remains unchanged and only the inner side 112 is pulled upward, the height position of the inner side 112 of the first driving medium 11a is higher than the height position of the outer side 111 of the first driving medium 11a, so that the outer side 111 and the inner side 112 have a height difference, and at this time, the first driving medium 11a is bent and deformed. Correspondingly, when a force is applied to the first driving medium 11a so that the height position of the outer side 111 remains unchanged and only the inner side 112 is pressed downward, the height position of the inner side 112 of the first driving medium 11a is lower than the height position of the outer side 111 of the first driving medium 11a, so that the outer side 111 and the inner side 112 have a height difference, and at this time, the first driving medium 11a is bent and deformed.

[0078] It is worth mentioning that the material of the first driving medium 11a is not limited in the manufacturing method of the present invention, as long as the material can allow the first driving medium 11a to bend and deform when the inner side 112 of the first driving medium 11a is subjected to force. For example, the first driving medium 11a can be made of but not limited to glass.

[0079] Reference Figure 1B The manufacturing method includes the steps of: (B) disposing a first driver 12a on the first driving medium 11a, so that the first driving medium 11a is allowed to bend and deform by applying force to the first driving medium 11a by the first driver 12a.

[0080] Preferably, in this preferred example of the manufacturing method of the present invention, the first driver 12a is a PZT driver (Piezoelectric Transducer), so that in the step (B), the first driver 12a is mounted on the first driving medium 11a to allow the first driver 12a to apply force to the first driving medium 11a to bend and deform the first driving medium 11a. By mounting the first driver 12a on the surface of the first driving medium 11a, on the one hand, the first driver 12a does not occupy the circumferential space of the first driving medium 11a, and on the other hand, the first driver 12a has a smaller thickness, which is conducive to reducing the thickness of the zoom lens unit 10.

[0081] Preferably, the first driver 12a is annular, and the first driver 12a extends outward to the medium outer side 111 of the first driving medium 11a, and extends inward to the medium inner side 112 of the first driving medium 11a.

[0082] Reference Figure 1C The manufacturing method further includes the steps of: (C) attaching a deformable first light-transmitting film 13a to the first driving medium 11a so that the first light-transmitting film 13a and the first driving medium 11a are combined into one, and the medium through hole 113 of the first driving medium 11a corresponds to the middle of the first light-transmitting film 13a, so that the first driver 12a drives the first light-transmitting film 13a through the first driving medium 11a to adjust the shape of the first light-transmitting film 13a.

[0083] In other words, the first driving medium 11a is located in the middle of the first driver 12a and the first light-transmitting film 13a, so that: on the one hand, the first driver 12a is prevented from directly contacting the first light-transmitting film 13a, so as to avoid the undesirable phenomenon that the first light-transmitting film 13a is directly subjected to force and is damaged, for example, it is possible to avoid the undesirable phenomenon that the first light-transmitting film 13a is directly pressurized by the first driver 12a and is damaged; on the other hand, the first driving medium 11a can evenly transmit the driving force to the first light-transmitting film 13a to cause the first light-transmitting film 13a to produce a consistent degree of deformation in the annular direction.

[0084] Continue to refer to the attached Figure 1CIn the manufacturing method of the present invention, after the first driver 12a is arranged on one side of the first driving medium 11a and the first light-transmitting film 13a is mounted on the other side of the first driving medium 11a, the first driver 12a, the first driving medium 11a and the first light-transmitting film 13a are combined into one body to manufacture a top-side driving module 1000a. In other words, the zoom lens unit 10 of the present invention includes the top-side driving module 1000a, wherein the top-side driving module 1000a includes the first driving medium 11a and the first driver 12a and the first light-transmitting film 13a respectively arranged on opposite sides of the first driving medium 11a.

[0085] Through the steps (A) to (C) of the manufacturing method of the present invention, the manufacturing method can further produce a bottom side driving module 1000b, that is, the zoom lens unit 10 of the present invention further includes a bottom side driving module 1000b, wherein the bottom side driving module 1000b includes a second driving medium 11b and a second driver 12b and a second light-transmitting film 13b respectively arranged on opposite sides of the second driving medium 11b.

[0086] It is worth mentioning that the structure of the bottom driving module 1000b is consistent with that of the top driving module 1000a, and the only difference between the two is that the bottom driving module 1000b and the top driving module 1000a are respectively arranged at different positions of the zoom lens unit 10.

[0087] Continue to refer to the attached Figure 1D and Figure 1E The manufacturing method further includes the steps of: (D) mounting the top driving module 1000a on the base top side 141 of the supporting base 14a by closing an opening of a ring-shaped supporting base 14 on a base top side 141 of the supporting base 14 with the first light-transmitting film 13a of the top driving module 1000a, and (E) mounting the bottom driving module 1000b on the base bottom side 142 of the supporting base 14 by closing an opening of a base bottom side 142 of the supporting base 14 with the second light-transmitting film 13b of the bottom driving module 1000b, so that the manufacturing method forms a holding space 15 between the supporting base 14, the first light-transmitting film 13a and the second light-transmitting film 13b, wherein an injection port 143 of the supporting base 14 is connected to the holding space 15.

[0088] Specifically, refer to the attached Figure 1DThe edge of the first light-transmitting film 13a is attached to the surface of the support base 14 on the top side 141 of the base, and the first light-transmitting film 13a closes the opening of the support base 14 on the top side 141 of the base. For example, the first light-transmitting film 13a and the support base 14 can be attached by but not limited to glue; refer to the attached Figure 1D The edge of the second light-transmitting film 13b is attached to the surface of the supporting base 14 on the bottom side 142 of the base, and the second light-transmitting film 13b closes the opening of the supporting base 14 on the bottom side 142 of the base. For example, the second light-transmitting film 13b and the supporting base 14 can be attached by but not limited to glue.

[0089] Reference Figure 1F and Figure 1G The manufacturing method further includes the steps of: (F) injecting fluid into the retaining space 15 through the injection port 143 of the support base 14, and (G) after the fluid fills the retaining space 15, closing the injection port 143 of the support base 14 to allow the fluid to form a refractive portion 16 in the retaining space 15, wherein the first light-transmitting film 13a defines a surface shape of a light incident surface 161 of the refractive portion 16, and the second light-transmitting film 13b defines a surface shape of a light emitting surface 162 of the refractive portion 16.

[0090] In the present invention, the refraction portion 16 is formed by a fluid that fills and is held in the holding space 15 of the zoom lens unit 10, so that: on the one hand, the refraction portion 16 is guaranteed to have no elastic modulus, and on the other hand, the curvature radius of the light entrance surface 161 and the curvature radius of the light exit surface 162 of the refraction portion 16 can be adjusted in a continuously variable manner. In this preferred example of the manufacturing method of the present invention, the fluid can be a liquid. Alternatively, in an optional example of the manufacturing method of the present invention, the refraction portion 16 is a low modulus jelly.

[0091] Preferably, the thickness of the refraction portion 16 is in the range of 0.15 mm to 0.3 mm (including 0.15 mm and 0.3 mm).

[0092] Reference Figure 1G, the intermediary outer side 111 of the first driving intermediary 11a corresponds to the supporting base 14 at the base top side 141 of the supporting base 14, the intermediary outer side 111 of the second driving intermediary 11b corresponds to the supporting base 14 at the base bottom side 142 of the supporting base 14, and the intermediary inner sides 112 of the first driving intermediary 11a and the second driving intermediary 11b extend to a suitable position in the central axis direction of the zoom lens unit 10 to define an effective edge position 163 of the refractive portion 16, wherein the effective edge position 163 of the refractive portion 16 sets the outermost position of the refractive portion 16 that allows light to pass through. In the present invention, the injection port 143 of the supporting base 14 is located outside the effective edge position 163 of the refractive portion 16, so as to avoid the setting of the injection port 143 of the supporting base 14 affecting the optical path of the zoom lens unit 10.

[0093] Continue to refer to the attached Figure 1G In the step (G) of the present invention, a sealing element 17 is allowed to be formed on the injection port 143 of the support base 14 to seal the injection port 143 of the support base 14, thereby allowing the holding space 15 of the zoom lens unit 10 to form a closed space and preventing the fluid used to form the refractive portion 16 from leaking through the injection port 143 of the support base 14, thereby ensuring the reliability of the zoom lens unit 10.

[0094] Reference Figure 1H The manufacturing method further includes the step of: (H) forming a conductive portion 18 on the outer side of the support base 14, and the two opposite sides of the conductive portion 18 extend respectively to conductively connect the first driver 12a and the second driver 12b, so that the conductive portion 18 can subsequently send electrical signals to the first driver 12a and the second driver 12b synchronously.

[0095] According to another aspect of the present invention, the manufacturing method of the zoom lens unit 10 of the present invention comprises the following steps:

[0096] (a) forming the holding space 15 between the support base 14 and the two deformable light-transmitting films 13;

[0097] (b) injecting fluid into the holding space 15 through the injection port 143 of the support base 14; and

[0098] (c) After the fluid fills the retaining space 15, the injection port 143 of the support base 14 is closed to allow the fluid to form the refractive portion 16 in the retaining space 15, wherein one of the two light-transmitting films 13 defines the surface shape of the light incident surface 161 of the refractive portion 16, and the other light-transmitting film 13 defines the surface shape of the light exit surface 162 of the refractive portion 16.

[0099] Specifically, in the step (a), the two light-transmitting films 13 are respectively implemented as the first light-transmitting film 13a and the second light-transmitting film 13b, wherein the first light-transmitting film 13a is attached to the supporting base 14 in a manner that the first light-transmitting film 13a closes the opening of the supporting base 14 on the top side 141 of the base, and the second light-transmitting film 13b is attached to the supporting base 14 in a manner that the second light-transmitting film 13b closes the opening of the supporting base 14 on the bottom side 142 of the base, so that the holding space 15 is formed between the first light-transmitting film 13a, the supporting base 14 and the second light-transmitting film 13b, and the injection port 143 of the supporting base 14 is connected to the holding space 15.

[0100] It is worth mentioning that the reference Figures 1D to 1H , the injection port 143 of the support base 14 is an injection groove, which extends from the outer wall to the inner wall of the support base 14, so that after the holding space 15 is formed between the first light-transmitting film 13a, the support base 14 and the second light-transmitting film 13b, the injection port of the support base 14 is connected to the holding space 15. Optionally, in other examples of the present invention, the injection port 143 of the support base 14 is an injection through hole, which extends from the outer wall to the inner wall of the support base 14, so that after the holding space 15 is formed between the first light-transmitting film 13a, the support base 14 and the second light-transmitting film 13b, the injection port of the support base 14 is connected to the holding space 15.

[0101] In the step (c), the sealing element 17 is formed at the injection port 143 of the support base 14 so that the injection port 143 of the support base 14 is sealed by the sealing element 17. In this way, the sealing element 17 enables the retaining space 15 to form a sealed space and prevents the fluid used to form the refractive portion 16 from leaking through the injection port 143 of the support base 14.

[0102] In the step (c), after the fluid fills the holding space 15 to form the refraction portion 16, the refraction portion 16 has the light incident surface 161 and the light emitting surface 162 corresponding to the light incident surface 161, wherein the first light-transmitting film 13a defines the surface shape of the light incident surface 161 of the refraction portion 16, and the second light-transmitting film 13b defines the surface shape of the light emitting surface 162 of the refraction portion 16. Preferably, the light incident surface 161 of the refraction portion 16 is attached to the first light-transmitting film 13a, and the light emitting surface 162 of the refraction portion 16 is attached to the second light-transmitting film 13b.

[0103] Furthermore, before the step (a), the manufacturing method further comprises the step of attaching the driving medium 11 to the side of each of the light-transmitting films 13 in such a manner that the middle of the light-transmitting film 13 corresponds to the medium through hole 113 of the driving medium 11, so as to allow the driving medium 11 and the light-transmitting film 13 to be combined into one, wherein the driving medium 11 can be bent and deformed to drive the light-transmitting film 13 to bend and deform synchronously and with the same amplitude. Optionally, after the step (c), the manufacturing method further comprises the step of attaching the driving medium 11 to the side of each of the light-transmitting films 13 in such a manner that the middle of the light-transmitting film 13 corresponds to the medium through hole 113 of the driving medium 11, so as to allow the driving medium 11 and the light-transmitting film 13 to be combined into one, wherein the driving medium 11 can be bent and deformed to drive the light-transmitting film 13 to bend and deform synchronously and with the same amplitude.

[0104] Specifically, the number of the driving agents 11 of the zoom lens unit 10 is two, namely the first driving agent 11a and the second driving agent 11b, wherein the first driving agent 11a and the first light-transmitting film 13a are combined into one, and correspondingly, the second driving agent 11b and the second light-transmitting film 13b are combined into one.

[0105] Further, the driving medium 11 is mounted with a driver 12, so that the driving medium 11 is subsequently driven by the driver 12 to bend and deform. For example, the first driving medium 11a is mounted with the first driver 12a, so that the first driving medium 11a is subsequently driven by the first driver 12a to bend and deform, and correspondingly, the second driving medium 11b is mounted with the second driver 12b, so that the second driving medium 11b is subsequently driven by the second driver 12b to bend and deform.

[0106] Specifically, the order of mounting the driving medium 11 on the light-transmitting film 13 and mounting the driver 12 on the driving medium 11 is not limited in the manufacturing method of the present invention. For example, in a specific example of the manufacturing method of the present invention, first, the driver 12 is mounted on the driving medium 11, and second, the driving medium 11 is mounted on the light-transmitting film 13; or in another specific example of the manufacturing method of the present invention, first, the driving medium 11 is mounted on the light-transmitting film 13, and second, the driver 12 is mounted on the driving medium 11.

[0107] Furthermore, the manufacturing method further comprises the step of allowing two opposite ends of the conductive portion 18 formed on the supporting base 14 to be conductively connected to the two drivers 12 .

[0108] Attached Figure 2 An optical lens 100' according to another preferred embodiment of the present invention is shown. Figures 3 to 4B A camera module 1000' according to another preferred embodiment of the present invention is shown, wherein the camera module 1000' includes a photosensitive component 200' and the optical lens 100' arranged in the photosensitive path of the photosensitive component 200', wherein the light reflected by the object can be received by the photosensitive component 200' after passing through the optical lens 100', so that the photosensitive component 200' can subsequently perform photoelectric conversion to form an image.

[0109] Reference Figures 3 to 4B The photosensitive component 200' includes a circuit board 201' and a photosensitive chip 202' conductively connected to the circuit board 201', wherein the optical lens 100' is maintained in the photosensitive path of the photosensitive chip 202', and the light reflected by the object can be converged by the optical lens 100' when passing through the optical lens 100', and can be received by the photosensitive chip 202' after passing through the optical lens 100', and then the photosensitive chip 202' performs photoelectric conversion to form an image.

[0110] More specifically, in the attached Figures 3 to 4BIn the specific example of the camera module 1000' shown, the photosensitive chip 202' is mounted on the circuit board 201', and the photosensitive component 200' includes at least one set of leads 203', and the two opposite ends of the leads 203' are respectively connected to the photosensitive chip 202' and the circuit board 201' to conductively connect the photosensitive chip 202' and the circuit board 201'. Optionally, in other examples of the camera module 1000' of the present invention, the photosensitive chip 202' is mounted on the circuit board 201', and the photosensitive chip 202' and the circuit board 201' are directly conductive, for example, the photosensitive chip 202' is mounted on the circuit board 201' in a flip-chip manner.

[0111] Continue to refer to the attached Figures 3 to 4B The photosensitive component 200' further includes a base 204', the base 204' has a light window 2041', wherein the photosensitive chip 202' is arranged on the circuit board 201', and the photosensitive area of ​​the photosensitive chip 202' corresponds to the light window 2041' of the base 204', wherein the optical lens 100' is arranged on the base 204' to maintain the optical lens 100' in the photosensitive path of the photosensitive chip 202'.

[0112] It is worth mentioning that the way the base 204' is arranged on the circuit board 201' is not limited in the camera module 1000' of the present invention. For example, the base 204' can be a prefabricated base, which is mounted on the circuit board 201', or the base 204' can be integrally combined with the circuit board 201' through a molding process, and the photosensitive area of ​​the photosensitive chip 202' corresponds to the light window 2041' of the base 204', so that there is no need to set glue between the base 204' and the circuit board 201', which is conducive to reducing the height size of the camera module 1000'. Preferably, the base 204' is further combined with the non-photosensitive area of ​​the photosensitive chip 202'. In other words, the base 204' is integrally combined with the circuit board 201' and the photosensitive chip 202', so that: first, there is no need to reserve a safety distance or mounting distance between the base 204' and the photosensitive chip 202', which is conducive to reducing the length and width of the camera module 1000'; second, the base 204' can ensure the flatness of the photosensitive chip 202', so that the circuit board 201' can choose a thinner plate, which is conducive to reducing the height of the camera module 1000'. ; On the third aspect, the base 204' is in direct contact with the photosensitive chip 202', so that the base 204' can directly conduct and radiate outward the heat generated by the photosensitive chip 202' during operation, so as to help reduce the operating temperature of the photosensitive chip 202'; on the fourth aspect, the base 204' can cover the lead 203', so as to help ensure the reliability of the welding position of the lead 203' and the circuit board 201' and ensure the reliability of the welding position of the lead 203' and the photosensitive chip 202'.

[0113] Continue to refer to the attached Figures 2 to 4B The optical lens 100' includes at least one zoom lens unit 10', wherein the zoom lens unit 10' includes a refractive portion 16', an annular supporting base 14' and two deformable light-transmitting films 13' and a retaining space 15', wherein the two light-transmitting films 13' are respectively arranged on opposite sides of the supporting base 14', and the retaining space 15' is formed between the two light-transmitting films 13' and the supporting base 14', wherein the refractive portion 16' fills and is retained in the retaining space 15', so that the shape of the refractive portion 16' is maintained by the supporting base 14' and the two light-transmitting films 13'.

[0114] Specifically, the support base 14' has a base top side 141' and a base bottom side 142' corresponding to the base top side 141', wherein one of the two light-transmitting films 13' is defined as a top-side light-transmitting film (first light-transmitting film) 13a', and the top-side light-transmitting film 13a' is disposed on the base top side 141' of the support base 14', and the other light-transmitting film 13' is defined as a bottom-side light-transmitting film (second light-transmitting film) 13b', and the bottom-side light-transmitting film 13b' is disposed on the base bottom side of the support base 14'. 142', so that the holding space 15' is formed between the top light-transmitting film 13a', the supporting base 14' and the bottom light-transmitting film 13b', wherein the refraction portion 16' has a light incident surface 161' and a light emitting surface 162' corresponding to the light incident surface 161', the refraction portion 16' fills and is retained in the holding space 15', and the top light-transmitting film 13a' defines and maintains the surface shape of the light incident surface 161' of the refraction portion 16', and the bottom light-transmitting film 13b' defines and maintains the surface shape of the light emitting surface 162' of the refraction portion 16'. The refraction portion 16' is configured to allow the surface shape of the light incident surface 161' of the refraction portion 16' to deform along with the deformation of the top light-transmitting film 13a', and to allow the surface shape of the light-emitting surface 162' of the refraction portion 16' to deform along with the deformation of the bottom light-transmitting film 13b', so that the surface shape of the light incident surface 161' and the surface shape of the light-emitting surface 162' of the refraction portion 16' of the zoom lens unit 10' can be adjusted, thereby realizing the zooming of the camera module 1000' without changing the relative positions of the photosensitive chip 202' and the optical lens 100'0 of the camera module 1000'.

[0115] More specifically, the edge of the top light-transmitting film 13a' is closely fitted to the surface of the top side 141' of the support base 14', so that the top light-transmitting film 13a' is arranged on the top side 141' of the support base 14', and the top light-transmitting film 13a' closes the opening of the support base 14' on the top side 141' of the base, and correspondingly, the edge of the bottom light-transmitting film 13b' is closely fitted to the surface of the bottom side 142' of the support base 14', so that the bottom light-transmitting film 13b' is arranged. The membrane 13b' is on the bottom side 142' of the supporting base 14', and the bottom side light-transmitting film 13b' closes the opening of the supporting base 14' at the bottom side 142' of the base, so that the zoom lens unit 10' of the optical lens 100' can form the holding space 15' between the top side light-transmitting film 13a', the supporting base 14' and the bottom side light-transmitting film 13b', and the zoom lens unit 10' can ensure that the refractive portion 16' is filled and held in the holding space 15'.

[0116] It is worth mentioning that the bonding method of the edge of the top side light-transmitting film 13a' and the surface of the top side 141' of the supporting base 14' and the bonding method of the edge of the bottom side light-transmitting film 13b' and the surface of the bottom side 142' of the supporting base 14' are not limited in the camera module 1000' of the present invention. For example, the edge of the top side light-transmitting film 13a' and the surface of the top side 141' of the supporting base 14' and the edge of the bottom side light-transmitting film 13b' and the surface of the bottom side 142' of the supporting base 14' can be bonded by glue to ensure that the top side light-transmitting film 13a' can close the side opening of the supporting base 14' on the top side 141' of the supporting base 14' and to ensure that the bottom side light-transmitting film 13b' can close the side opening of the supporting base 14' on the bottom side 142' of the supporting base.

[0117] Preferably, the light incident surface 161' of the refractive portion 16' is attached to the top side light transparent film 13a' to allow the top side light transparent film 13a' to define and maintain the surface shape of the light incident surface 161' of the refractive portion 16', so that the surface shape of the light incident surface 161' of the refractive portion 16' can be deformed synchronously and to the same extent as the deformation of the top side light transparent film 13a'. Correspondingly, the light emitting surface 162' of the refractive portion 16' is attached to the bottom side light transparent film 13b' to allow the bottom side light transparent film 13b' to define and maintain the surface shape of the light emitting surface 162' of the refractive portion 16', so that the surface shape of the light emitting surface 162' of the refractive portion 16' can be deformed synchronously and to the same extent as the deformation of the bottom side light transparent film 13b'. By allowing the surface shape of the light incident surface 161' of the refractive portion 16' to be deformed synchronously and to the same extent as the deformation of the top light-transmitting film 13a', and allowing the surface shape of the light-emitting surface 162' to be deformed synchronously and to the same extent as the deformation of the bottom light-transmitting film 13b', the camera module 1000' can easily achieve zooming by adjusting the shapes of the top light-transmitting film 13a' and the bottom light-transmitting film 13b', and can easily control the zoom accuracy.

[0118] Preferably, the refractive portion 16' is fluid, such as liquid, so that: on the one hand, the refractive portion 16' is ensured to have no elastic modulus to allow the zoom accuracy of the camera module 1000' to be further precisely controlled; on the other hand, the curvature radius of the light incident surface 161' and the curvature radius of the light exit surface 162' of the refractive portion 16' can be adjusted in a continuously variable manner to achieve continuous zoom of the camera module 1000'.

[0119] It is worth mentioning that the material type of the light-transmitting film 13' is not limited in the camera module 1000' of the present invention, as long as it can ensure that the opening of the support base 14' at the top side 141' of the base and the opening of the bottom side 142' of the base are closed and can be deformed when subjected to force. The material type of the support base 14' is not limited in the camera module 1000' of the present invention, as long as it can remain unchanged when the light-transmitting film 13' is subjected to force, for example, the support base 14' can be made of glass or metal.

[0120] Continue to refer to the attached Figures 3 to 4BThe camera module 1000' has a central axis 1001', wherein the central axis 1001' of the camera module 1000' coincides with the central axis of the refraction portion 16' of the zoom lens unit 10', and the deformation degree of the refraction portion 16' is consistent throughout the entire annular position of the refraction portion 16' from the central axis 1001' of the camera module 1000', thereby facilitating the precise control of the light path of the camera module 1000' after zooming, thereby ensuring the reliability of the camera module 1000'.

[0121] For ease of understanding, three annular positions are arbitrarily selected from the light incident surface 161' of the refractive portion 16', namely a first annular position 1611', a second annular position 1612' and a third annular position 1613', the distance between any point of the first annular position 1611' and the central axis 1001' of the camera module 1000' is equal, the distance between any point of the second annular position 1612' and the central axis 1001' of the camera module 1000' is equal, the distance between any point of the third annular position 1613' and the central axis 1001' of the camera module 1000' is equal, and the second annular position 1612' is located outside the first annular position 1611', and the third annular position 1613' is located outside the second annular position 1612'. Regardless of whether the light-transmitting film 13' of the zoom lens unit 10' is subjected to force to adjust the surface shapes of the light-entering surface 161' and the light-exiting surface 162' of the refractive portion 16' to achieve the zooming of the camera module 1000' or after the zooming, the deformation degree of each point of the refractive portion 16' at the first annular position 1611' is consistent, the deformation degree of each point of the refractive portion 16' at the second annular position 1612' is consistent, and the deformation degree of each point of the refractive portion 16' at the third annular position 1613' is consistent. Moreover, the deformation degree of the refractive portion 16' at the third annular position 1613' is greater than the deformation degree at the second annular position 1612', and accordingly, the deformation degree of the refractive portion 16' at the second annular position 1612' is greater than the deformation degree of the first annular position 1611'.

[0122] Preferably, no matter whether the light-transmitting film 13' of the zoom lens unit 10' is subjected to force to adjust the surface shapes of the light-entering surface 161' and the light-emitting surface 162' of the refractive portion 16' to realize the zooming of the camera module 1000' or after the zooming, the surface curvatures of the light-entering surface 161' and the light-emitting surface 162' of the refractive portion 16' from the central axis of the refractive portion 16' to the effective edge position 163' of the refractive portion 16' are monotonic, wherein the effective edge position 163' of the refractive portion 16' refers to the outermost position of the refractive portion 16' that allows light to pass through. In other words, the deformation degree of the surface shapes of the light-entering surface 161' and the light-emitting surface 162' of the refractive portion 16' near the effective edge position 163' is greater than the deformation degree near the central axis.

[0123] Continue to refer to the attached Figures 2 to 4B The zoom lens unit 10' further includes two annular driving agents 11' and two drivers 12', wherein the driving agent 11' has a medium through hole 113', the driving agent 11' is attached to the light-transmitting film 13', so that the driving agent 11' and the light-transmitting film 13' are combined into one, the middle part of the light-transmitting film 13' corresponds to the medium through hole 113' of the driving agent 11', and the driving agent 11' defines the effective edge position 163' of the refraction portion 16', wherein the driver 12' drives the refraction portion 16' through the driving agent 11'. The light-transmitting film 13' is moved to adjust the shape of the light-transmitting film 13'. In this way, on the one hand, the optical lens 100' can prevent the driver 12' from directly contacting the light-transmitting film 13', so as to avoid the undesirable phenomenon that the light-transmitting film 13' is directly subjected to force and is damaged. For example, it can avoid the undesirable phenomenon that the light-transmitting film 13' is directly pressed by the driver 12' and is damaged. On the other hand, the driving medium 11' can evenly transmit the driving force to the light-transmitting film 13' so that the light-transmitting film 13' produces a uniform degree of deformation in the annular direction.

[0124] For ease of description and understanding, one of the two driving agents 11' is defined as a top-side driving agent (first driving agent) 11a', and the top-side driving agent 11a' is adhered to the top-side light-transmitting film 13a' so that the top-side driving agent 11a' and the top-side light-transmitting film 13a' are combined into one body, and the other driving agent 11' is defined as a bottom-side driving agent (second driving agent) 11b', and the bottom-side driving agent 11b' is adhered to the bottom-side light-transmitting film 13b' so that the bottom-side driving agent 11b' and the bottom-side light-transmitting film 13b' are combined into one body. Correspondingly, one of the two drivers 12' is defined as a top side driver (first driver) 12a', which is used to drive the top side driving medium 11a' to cause the top side driving medium 11a' to bend and deform, and the other driver 12 is defined as a bottom side driver (second driver) 12b', which is used to drive the bottom side driving medium 11b' to cause the bottom side driving medium 11b' to bend and deform.

[0125] It is worth mentioning that the type of the driver 12' of the zoom lens unit 10' is not limited in the camera module 1000' of the present invention. Figures 3 to 4B In the specific example of the camera module 1000' shown, the driver 12' of the zoom lens unit 10' may be a PZT driver (Piezoelectric Transducer), which is mounted on the driving medium 11' and is used to drive the driving medium 11' to generate bending deformation, which is conducive to miniaturization of the optical lens 100' and further reducing the size of the camera module 1000'. Figures 3 to 4B In the specific example of the camera module 1000' shown, the zoom lens unit 10' further includes a conductive portion 18', wherein the conductive portion 18' is arranged on the outside of the support base 14', and the two ends of the conductive portion 18' are respectively extended to be conductively connected to the top side driver 12a' and the bottom side driver 12b', and the camera module 1000' can synchronously send electrical signals to the top side driver 12a' and the bottom side driver 12b' through the conductive portion 18', thereby allowing the top side driver 12a' and the bottom side driver 12b' to synchronously drive the top side transparent film 13a' and the bottom side transparent film 13b' to bend and deform through the top side driving medium 11a' and the bottom side driving medium 11b' on opposite sides of the zoom lens unit 10', thereby synchronously adjusting the surface shapes of the light incident surface 161' and the light exit surface 162' of the refractive portion 16'. Preferably, the conducting portion 18 ′ may be conductive silver paste.

[0126] Further, see Attachment Figures 2 to 4B The top-side driving medium 11a' and the bottom-side driving medium 11b' respectively have a medium outer side 111' and a medium inner side 112' corresponding to the medium outer side 111', and the medium inner side 112' defines the medium through hole 113'. The outer side 111' of the top-side driving medium 11a' corresponds to the supporting base 14' on the base top side 141' of the supporting base 14', and the inner side 112' of the top-side driving medium 11a' extends to a suitable distance in the direction of the central axis 1001' of the camera module 1000' to define the effective edge position 163' of the refractive portion 16', wherein the top-side driving medium 11a' can be driven by the top-side driver 12a' to bend and deform in such a manner that the relative positions of the outer side 111' of the top-side driving medium 11a' and the supporting base 14' remain unchanged and the inner side 112' of the top-side driving medium 11a' moves upward or downward, correspondingly The outer side 111' of the bottom side driving medium 11b' corresponds to the supporting base 14' on the bottom side 142' of the base of the supporting base 14', and the inner side 112' of the bottom side driving medium 11b' extends to a suitable distance in the direction of the central axis 1001' of the camera module 1000' to define the effective edge position 163' of the refractive portion 16', wherein the bottom side driving medium 11b' can be driven by the bottom side driver 12b' to bend and deform in such a way that the relative positions of the outer side 111' of the bottom side driving medium 11b' and the supporting base 14' remain unchanged and the inner side 112' of the bottom side driving medium 11b' moves downward or upward.

[0127] When the top-side driving medium 11a' is bent and deformed in a manner that the inner side 112' of the top-side driving medium 11a' moves downward, the top-side driving medium 11a' uniformly applies pressure to the top-side light-transmitting film 13a' in the entire annular direction, causing the top-side light-transmitting film 13a' to deform synchronously and with the same amplitude. At this time, the surface shape of the light-incident surface 161' of the refractive portion 16' is deformed synchronously and with the same amplitude as the deformation of the top-side light-transmitting film 13a' to present a convex surface shape. Accordingly, when the bottom-side When the driving medium 11b' is bent and deformed in such a manner that the inner side 112' of the bottom driving medium 11b' moves upward, the bottom driving medium 11b' uniformly applies pressure to the bottom light-transmitting film 13b' in the entire annular direction, causing the bottom light-transmitting film 13b' to deform synchronously and with the same amplitude. At this time, the surface shape of the light-emitting surface 162' of the refractive portion 16' is deformed synchronously with the deformation of the bottom light-transmitting film 13b' to present a convex surface shape, thereby realizing the zoom of the camera module 1000'. When the top-side driving medium 11a' is bent and deformed in a manner that the inner side 112' of the top-side driving medium 11a' moves upward, the top-side driving medium 11a' pulls the top-side light-transmitting film 13a' uniformly in the entire annular direction to cause the top-side light-transmitting film 13a' to deform synchronously and with the same amplitude. At this time, the surface shape of the light-incident surface 161' of the refractive portion 16' is deformed synchronously and with the same amplitude as the deformation of the top-side light-transmitting film 13a' to present a concave surface shape. Accordingly, when the bottom-side When the driving medium 11b' is bent and deformed in such a manner that the inner side 112' of the bottom driving medium 11b' moves downward, the bottom driving medium 11b' evenly pulls the bottom light-transmitting film 13b' in the entire annular direction so that the bottom light-transmitting film 13b' is deformed synchronously and with the same amplitude. At this time, the surface shape of the light-emitting surface 162' of the refractive portion 16' is deformed synchronously with the deformation of the bottom light-transmitting film 13b' to present a concave surface shape, thereby realizing the zoom of the camera module 1000'. In the above manner, the zoom of the camera module 1000' can be achieved without changing the relative positions of the photosensitive chip 202' and the optical lens 100' of the camera module 1000', thereby effectively reducing the height dimension of the zoom type camera module 1000', and the zoom type camera module 1000' can also be applied to the front side of the electronic device to form a front camera module.

[0128] Continue to refer to the attached Figures 2 to 4BThe optical lens 100' further includes a lens barrel 20', the zoom lens unit 10' is assembled to the lens barrel 20', and the lens barrel 20' is directly assembled to the base 204' of the photosensitive component 200' to maintain the light sensing path of the optical lens 100' and the photosensitive chip 202', wherein the camera module 1000' can adjust the light incident surface 161' and the light exit surface 162 of the refractive portion 16' of the zoom lens unit 10' of the optical lens 100' without changing the relative position of the optical lens 100' and the photosensitive chip 202'. ' surface-shaped manner can realize the zoom of the camera module 1000'. In this way, on the one hand, the camera module 1000' does not need to reserve a travel space for the movement of the optical lens 100' and the height of the camera module 1000' can be reduced. On the other hand, by omitting the zoom motor of the existing camera module, the length and width of the camera module 1000' of the present invention corresponding to the optical lens 100' can be reduced, so that the camera module 1000' with zoom capability of the present invention is suitable for electronic devices that pursue lightness and thinness or is applied to the front side of electronic devices to form a front camera module.

[0129] Continue to refer to the attached Figures 2 to 4B The optical lens 100' further includes at least one lens 30', wherein the lenses 30' are assembled to the lens barrel 20' to allow the lenses 30' and the zoom lens unit 10' to form a complete optical system.

[0132] Preferably, the refractive portion 16' has a relatively high refractive index, and its lowest refractive index is 1.2, so that when the surface angle of the refractive portion 16' is relatively small, the camera module 1000' can also have a relatively large zoom range. That is, for the camera module 1000', the higher the refractive index of the refractive portion 16', the smaller the surface angle of the refractive portion 16' when the focal length is changed to the same value.

[0133] Reference Figures 3 to 4B , let the two relative points of the light incident surface 161' of the refraction portion 16' corresponding to the inner edge of the top driving medium 11a' be A and A', wherein the line between A and A' intersects with the central axis 1001' of the camera module 1000', let the two relative points of the light emitting surface 162' of the refraction portion 16' corresponding to the inner edge of the bottom driving medium 11b' be B and B', wherein the line between B and B' intersects with the central axis 1001' of the camera module 1000'. 01' intersects, wherein the two points on the central axis 1001' of the camera module 1000' are C and D respectively, wherein the line between point A and C is L1, the line between point A' and C is L2, and the angle formed between L1 and L2 is θ1, correspondingly, the line between point B and D is L3, the line between point B' and D is L4, and the angle formed between L3 and L4 is θ2, taking the refractive index of the refractive portion 16' as 1.55 as an example, the minimum value of θ1+θ2 is 7.5°. It can be understood that the lower the refractive index of the refractive portion 16', the greater the minimum value of the sum of the angle θ1 between L1 and L2 and the angle θ2 between L3 and L4.

[0134] Preferably, the transmittance of the optical lens 100' is greater than or equal to 90%, and the transmittance of the refraction portion 16' is greater than or equal to 95%. More preferably, the transmittances of the top side transparent film 13a' and the bottom side transparent film 13b' of the transparent film 13' are both greater than the transmittance of the refraction portion 211 to ensure the transmittance of the optical lens 100'.

[0135] In a specific example of the camera module 1000' of the present invention, the aperture diameter of the optical lens 100' can be 4 mm, wherein the diameter of the effective light-transmitting area of ​​the refractive portion 16' is at least 4.5 mm, that is, the diameter of the effective light-transmitting area of ​​the refractive portion 16' is at least 0.5 mm larger than the diameter of the aperture, and in order to ensure a smooth optical path, no light-blocking coating or structure may be provided within the aperture of the aperture.

[0136] Continue to refer to the attached Figures 2 to 4B The support base 14' of the zoom lens unit 10' has an injection port 143', and the injection port 143' of the support base 14' is connected to the holding space 15', wherein a fluid is arranged to be injected through the injection port 143' of the support base 14' and fill the holding space 15' to form the refractive portion 16'. At this time, the fluid filling the holding space 15' presses against the top side transparent film 13a' and the light incident surface 161' of the refractive portion 16' is defined by the top side transparent film 13a'. Correspondingly, the fluid filling the holding space 15' presses against the bottom side transparent film 13b' and the light exit surface 162' of the refractive portion 16' is defined by the bottom side transparent film 13b'. The zoom lens unit 10' further includes a sealing element 17', wherein the sealing element 17' is formed at the injection port 143' of the support base 14' to seal the injection port 143' of the support base 14', so that the holding space 15' of the zoom lens unit 10' forms a closed space to prevent the fluid used to form the refractive portion 16' from leaking out through the injection port 143' of the support base 14'. Preferably, the conducting portion 18' is hidden by the sealing element 17 and is not visible.

[0137] Reference Figure 5 The present invention further provides an electronic device, which includes an electronic device body 2000' and the camera module 1000' arranged on the rear side of the electronic device body 2000', wherein the electronic device body 2000' can receive and process the electronic device body 2000' after the camera module 1000' receives the light reflected by the object and performs photoelectric conversion to obtain an electrical signal about the object, so as to be subsequently stored in the memory of the electronic device body 2000' and / or displayed on the display screen of the electronic device body 2000'.
