Description

Zoom lens unit, method of manufacturing the same, and application of the zoom lens unit

Technical Field

The present invention relates to the field of optical imaging, and more particularly, to a zoom lens unit, a method of manufacturing the same, and an application of the zoom lens unit.

Background

The optical lens for an optical path is a component of a camera module, which is composed of a lens barrel and a lens disposed on the lens barrel. The lens (e.g., a glass lens or a resin lens) of an existing optical lens has an incident surface and an exit surface, and the surface type of the incident surface and the surface type of the exit surface of the lens are determined, so that the optical path of the optical lens is determined, and therefore, to implement zooming of a camera module, zooming can be implemented only by changing the relative positions of the optical lens and a photo sensor chip of the camera module.

However, the conventional camera module is not suitable for the electronic device with a thin structure, for the following reasons: firstly, the camera module needs to reserve a stroke space for the optical lens to move along the optical axis, so that the height size of the camera module cannot be reduced; secondly, the camera module needs to have a zoom motor around the optical lens, so that the length and width of the camera module at the position corresponding to the optical lens cannot be reduced.

Further, since the camera module has a large length and width at a portion corresponding to the optical lens due to the zoom motor being disposed around the optical lens, the camera module having the zoom capability is not suitable for forming a front camera module by being applied to a front side of the camera module which seeks a high screen ratio.

Referring to fig. 1A to 1H of the drawings accompanying the present specification, a zoom lens unit 10 and a method of manufacturing the zoom lens unit 10 according to a preferred embodiment of the present invention will be disclosed and explained in the following description.

Referring to fig. 1A, the manufacturing method includes the steps of: (A) Providing a flexible first driving medium 11a, wherein the first driving medium 11a has a medium outer side 111, a medium inner side 112 and a medium through hole 113, the medium outer side 111 and the medium inner side 112 correspond to each other, and the medium inner side 112 defines the medium through hole 113, so that the first driving medium 11a is ring-shaped.

The first drive medium 11a is bendable. Specifically, the intermediate outer side 111 and the intermediate inner side 112 of the first drive intermediate 11a may have a height difference when applying a force to the first drive intermediate 11a, and the height difference of the intermediate outer side 111 and the intermediate inner side 112 is determined by the driving force applied to the first drive intermediate 11 a. More specifically, the external force applied to the first driving medium 11a can ensure that the height position of the medium outer side 111 of the first driving medium 11a remains unchanged and only the medium inner side 112 of the first driving medium 11a is driven to move upward or downward, such that the medium outer side 111 and the medium inner side 112 of the first driving medium 11a have a height difference to allow the first driving medium 11a to be bent and deformed.

For example, when the first drive medium 11a is in an initial state in which the medium outer side 111 and the medium inner side 112 are at the same height position, and a force is applied to the first drive medium 11a to keep the height position of the medium outer side 111 unchanged and pull up only the medium inner side 112, the height position of the medium inner side 112 of the first drive medium 11a is higher than the height position of the medium outer side 111 of the first drive medium 11a to cause a difference in height between the medium outer side 111 and the medium inner side 112, and the first drive medium 11a is bent and deformed. Accordingly, when the first driving medium 11a is applied with a force to maintain the height position of the medium outer side 111 and to press down only the medium inner side 112, the height position of the medium inner side 112 of the first driving medium 11a is lower than the height position of the medium outer side 111 of the first driving medium 11a to have a difference in height between the medium outer side 111 and the medium inner side 112, and at this time, the first driving medium 11a is bent and deformed.

It should be noted 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 medium inner side 112 of the first driving medium 11a is stressed, and for example, the first driving medium 11a may be, but not limited to, a glass material.

Referring to fig. 1B, the manufacturing method includes the steps of: (B) A first driver 12a is disposed on the first driving medium 11a, so that the first driver 12a applies force to the first driving medium 11a to allow the first driving medium 11a to bend and deform.

Preferably, in this preferred example of the manufacturing method of the present invention, the first actuator 12a is a PZT actuator (Piezoelectric Transducer), so that in the step (B), the first actuator 12a is attached to the first actuating medium 11a to allow the first actuator 12a to apply a force to the first actuating medium 11a to cause the first actuating medium 11a to be bent and deformed. By mounting the first driver 12a on the surface of the first driving medium 11a, on one hand, the first driver 12a may 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 beneficial to reducing the thickness dimension of the zoom lens unit 10.

Preferably, the first driver 12a is ring-shaped, and the first driver 12a extends outwardly to the intermediate outer side 111 of the first drive intermediate 11a and inwardly to the intermediate inner side 112 of the first drive intermediate 11 a.

Referring to fig. 1C, the manufacturing method further includes the steps of: (C) Attaching a deformable first transparent film 13a to the first driving medium 11a, so that the first transparent film 13a and the first driving medium 11a are integrated, and the medium through hole 113 of the first driving medium 11a corresponds to the middle of the first transparent film 13a, so that the first driver 12a drives the first transparent film 13a through the first driving medium 11a to adjust the shape of the first transparent film 13a.

In other words, the first driving medium 11a is located in the middle of the first driver 12a and the first transparent film 13a, such that: on one hand, the first driver 12a is prevented from directly contacting the first transparent film 13a, so as to avoid a bad phenomenon that the first transparent film 13a is damaged due to direct force, for example, the first transparent film 13a is damaged due to direct pressure applied by the first driver 12a, and on the other hand, the first driving medium 11a can uniformly transmit driving force to the first transparent film 13a, so that the first transparent film 13a deforms in a uniform degree in a circular direction.

With continued reference to fig. 1C, after disposing the first driver 12a on one side of the first driving medium 11a and attaching the first transparent film 13a on the other side of the first driving medium 11a, the first driver 12a, the first driving medium 11a and the first transparent film 13a are combined into a single body to form 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 agent 11a and the first driver 12a and the first light-transmissive film 13a respectively disposed on opposite sides of the first driving agent 11 a.

Through the steps (a) to (C) of the manufacturing method of the present invention, the manufacturing method can further manufacture 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-transmissive film 13b respectively disposed on opposite sides of the second driving medium 11 b.

It is worth mentioning that the structure of the bottom side driving module 1000b and the structure of the top side driving module 1000a are identical, and the difference therebetween is only that the bottom side driving module 1000b and the top side driving module 1000a are respectively disposed at different positions of the zoom lens unit 10.

With continued reference to fig. 1D and 1E, the method of manufacturing further includes the steps of: (D) Mounting the top side driving module 1000a on a base top side 141 of a ring-shaped supporting base 14 in such a manner that the first transparent film 13a of the top side driving module 1000a closes an opening of the supporting base 14 on the base top side 141 of the supporting base 14, and (E) mounting the bottom side driving module 1000b on the base bottom side 142 of the supporting base 14 in such a manner that the second transparent film 13b of the bottom side driving module 1000b closes an opening of the supporting base 14 on a base bottom side 142 of the supporting base 14, such that the manufacturing method forms a holding space 15 among the supporting base 14, the first transparent film 13a and the second transparent film 13b, wherein an inlet 143 of the supporting base 14 is communicated with the holding space 15.

Specifically, referring to fig. 1D, an edge of the first transparent film 13a is attached to the surface of the support base 14 on the base top side 141, and the first transparent film 13a closes the opening of the support base 14 on the base top side 141, for example, but not limited to, the first transparent film 13a and the support base 14 may be attached by glue; referring to fig. 1D, an edge of the second transparent film 13b is attached to the surface of the support base 14 on the base bottom side 142, and the second transparent film 13b closes the opening of the support base 14 on the base bottom side 142, for example, but not limited to, the second transparent film 13b and the support base 14 can be attached by glue.

Referring to fig. 1F and 1G, the manufacturing method further includes the steps of: (F) Injecting a fluid into the holding space 15 through the injection port 143 of the supporting base 14, and (G) after the fluid fills the holding space 15, closing the injection port 143 of the supporting base 14 to allow the fluid to form a light refracting part 16 in the holding space 15, wherein the first light-transmitting film 13a defines a surface shape of a light incident surface 161 of the light refracting part 16, and the second light-transmitting film 13b defines a surface shape of a light exiting surface 162 of the light refracting part 16.

In the present invention, the refractive portion 16 is formed of a fluid filled and held in the holding space 15 of the zoom lens unit 10, such that: on the one hand, the refractive portion 16 is guaranteed to have no elastic modulus, and on the other hand, the curvature radius of the light incident surface 161 and the curvature radius of the light emitting surface 162 of the refractive portion 16 can be adjusted in a continuously variable manner. In this preferred example of the manufacturing method of the invention, the fluid may be a liquid. Alternatively, in an alternative example of the manufacturing method of the present invention, the refraction portion 16 is a low modulus jelly.

Preferably, the thickness of the refractive portion 16 ranges from 0.15mm to 0.3mm (including 0.15mm and 0.3 mm)

Referring to fig. 1G, the intermediate outer side 111 of the first driving intermediate 11a corresponds to the support base 14 at the base top side 141 of the support base 14, the intermediate outer side 111 of the second driving intermediate 11b corresponds to the support base 14 at the base bottom side 142 of the support base 14, and the intermediate inner sides 112 of the first driving intermediate 11a and the second driving intermediate 11b extend to positions 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 where the refractive portion 16 allows light to pass through. In the present invention, the injection port 143 of the support base 14 is located outside the effective edge position 163 of the refractive portion 16, so as to avoid the arrangement of the injection port 143 of the support base 14 from affecting the optical path of the zoom lens unit 10.

With continued reference to fig. 1G, in step (G) of the present invention, a sealing member 17 is allowed to be formed at the injection port 143 of the support base 14 for sealing the injection port 143 of the support base 14, thus allowing the holding space 15 of the zoom lens unit 10 to form a sealed space while preventing the fluid for forming the refractive portion 16 from leaking out through the injection port 143 of the support base 14, thereby ensuring reliability of the zoom lens unit 10.

Referring to fig. 1H, the manufacturing method further includes the steps of: (H) A conduction part 18 is formed at the outer side of the supporting base 14, and opposite sides of the conduction part 18 extend to conductively connect the first driver 12a and the second driver 12b, respectively, so that an electrical signal can be synchronously transmitted to the first driver 12a and the second driver 12b through the conduction part 18 at a later time.

In accordance with another aspect of the present invention, the method of manufacturing the zoom lens unit 10 of the present invention includes the steps of:

(a) Forming said holding space 15 between said support base 14 and two deformable light-transmissive films 13;
