Description

Lens Module

This invention relates to an optical module, and more particularly to a lens module.

Most common lens modules use motors or other driving components to move the lens to adjust the focal length. However, these driving components need to be connected to the lens via structures such as fixing elements, which increases the overall height and weight of the lens module. How to reduce the overall height and weight of the lens module to meet the trend of thinness and miniaturization is one of the topics that engineers in this field are working hard to research.

This invention provides a lens module that does not require additional fixing components, thereby reducing the height and weight of the lens module.

According to one embodiment of the present invention, a lens module is provided, including a housing, a carrier, a first driving component, a second driving component, a transmission component, and an image sensor. The carrier is located within the housing and includes a vertically connected upright portion and a supporting portion. The first driving component is disposed on the upright portion. The second driving component is disposed within the housing and corresponds to the first driving component, and the first driving component is adapted to drive the carrier to move relative to the second driving component and the housing along an incident light direction. The transmission component is located within the housing and above the supporting portion, and includes a movable portion, two curved portions, and a fixed portion connected in sequence. The movable part is connected to the support part, and the two ends of the curved part are respectively connected to the movable part and the fixed part. The two curved parts are symmetrically positioned on opposite sides of the movable part, and the vertical projection of the two curved parts on one bottom surface of the housing does not overlap with the vertical projection of the support part on the bottom surface. The image sensor is located inside the housing and on the transmission component, and the image sensor is electrically connected to the transmission component.

In one embodiment of this invention, the movable part has a horizontal segment and a vertical segment connected vertically. The vertical segment is adjacent to the upright part, and the horizontal segment extends away from the upright part. There are two spaces between the horizontal segment, the vertical segment, and the fixed part to accommodate the two curved parts. The vertical projection of the horizontal segment onto the image sensor passes through the center of the image sensor, and there is a gap between the fixed part and the movable part, which is away from the upright part.

In one embodiment of this invention, the two curved portions extend from the transverse segment in a direction parallel to the transverse segment, and the two curved portions bend back and forth between the straight segment and the fixed portion in a direction away from the transverse segment.

In one embodiment of this invention, the two curved sections each have at least one curved line, and the at least one curved line extends from the end of the transverse section away from the fixed part and bends back four times before connecting to the fixed part.

In one embodiment of this invention, the two curved portions extend from the transverse segment in a direction parallel to the vertical segment, and the two curved portions bend back and forth between the vertical segment and the fixed portion in a direction away from the vertical segment.

In one embodiment of this invention, the two curved sections each have at least one curved line, and the at least one curved line extends from the end of the transverse section away from the fixed part and bends back nine times before connecting to the fixed part.

In one embodiment of this invention, the two curved portions extend from the straight section in a direction parallel to the transverse section, and the two curved portions bend toward the center of each of the two spaces and then bend away from the center to connect to the fixing portion.

In one embodiment of this invention, the two curved portions each have at least one curved line, and the at least one curved line extends from one end of the straight segment away from the transverse segment and bends vertically toward the center nine times and then bends vertically away from the center ten times to connect to the fixed portion.

In one embodiment of this invention, the aforementioned fixing part has a connecting section and an extension section that are interconnected. The connecting section is located inside the shell and connects to the two curved sections, the extension section is located outside the shell, and the area of the two curved sections is greater than 70% of the total area of the two curved sections, the movable part, and the connecting section.

In one embodiment of this invention, the stiffness of the aforementioned transmission element is less than 90 mN/mm.

In one embodiment of this invention, one of the first driving component and the second driving component is at least one magnetic element, and the other of the first driving component and the second driving component includes a magnetically conductive element and a coil. The magnetically conductive element corresponds to the at least one magnetic element. The coil corresponds to the at least one magnetic element and is electrically connected to the transmission element. The coil is adapted to generate a magnetic field and interact with the magnetic force of the at least one magnetic element, thereby driving the carrier to move along the incident light direction.

In one embodiment of this invention, the housing includes an upper housing and a base. The upper housing covers the base. The base accommodates a second drive assembly, a support portion, a movable portion, two curved portions, and an image sensor. An upright portion is located between the upper housing and the base.

In one embodiment of this invention, the lens module further includes multiple sliding members located between the upright portion and the housing, so that the upright portion moves relative to the second drive assembly and the housing in the direction of incident light by the multiple sliding members resting against the housing.

In one embodiment of this invention, the camera module further includes a circuit board, a solder, and a primer.

In one embodiment of this invention, the aforementioned camera module further includes a metal plate disposed between the support and the housing.

In one embodiment of this invention, the lens module further includes a lens disposed within the housing and above the image sensor, with a first driving component, a second driving component, and an upright portion on one side of the lens.

Based on the above, the lens module of this invention utilizes the interaction of magnetic forces between the coil and the magnetic component, enabling the first driving component to move the carrier relative to the second driving component relative to the housing along the light-incident direction. Through this design, the lens module of this invention eliminates the need for additional fixing components, thus reducing the overall height and weight of the lens module.

Reference will now be made to exemplary embodiments of this invention, examples of which are illustrated in the accompanying drawings. Wherever possible, identical element symbols are used in the drawings and description to denote identical or similar parts.

Figure 1 is a perspective view of a lens module according to an embodiment of the present utility model. Figure 2 is an exploded view of the lens module of Figure 1. Figure 3 is an exploded view of the support member, the first drive component, the second drive component, and the sliding member of Figure 1. Figure 4A is a cross-sectional view of the lens module along section line A-A' of Figure 1.

Referring to Figures 1 to 4A, the lens module 100 of this embodiment includes a housing 110 and a lens 190. The housing 110 includes an upper housing 111 and a base 112. The base 112 includes a detachable bracket 1121 and a bottom housing 1122. The upper housing 111 covers the bracket 1121 of the base 112 and is located on the bottom housing 1122 of the base 112. The lens 190 is disposed in the housing 110 and is exposed to the outside through an opening 1111 in the upper housing 111 and an opening 1125 in the bracket 1121, allowing external light to enter the interior of the housing 110 through the lens 190.

Furthermore, the lens module 100 of this embodiment includes a support member 120, a first drive assembly 130, and a second drive assembly 140. The support member 120 is located within the housing 110 and includes a vertically connected upright portion 121 and a support portion 122. The upright portion 121 is located between the upper housing 111 and the base 112 and is situated on one side 191 of the lens 190. The support portion 122 is accommodated within the base 112 and is positioned above the bottom housing 1122 and below the lens 190. The first drive assembly 130 is disposed on the upright portion 121 and is situated on the side 191 of the lens 190. The second drive assembly 140 is disposed and housed within the base 112 and located on the side 191 of the lens 190, and the second drive assembly 140 corresponds to the first drive assembly 130. The first drive assembly 130 is adapted to drive the carrier 120 to move relative to the second drive assembly 140 and the housing 110 along an incident light direction LD.

Figure 4B is an enlarged schematic diagram of the lens module in Figure 4A. Figure 5 is a side view of the lens module in Figure 1. It should be noted that the upper housing 111 is omitted in Figure 5, and the support 120 is shown in perspective.

Referring to Figures 3 to 5, specifically, the first driving component 130 of this embodiment includes a magnetic conductor 131, a coil 132, and a magnetic sensing element 133. The second driving component 140 is a magnetic element 141. The magnetic conductor 131 is disposed within the upright portion 121 and corresponds to the magnetic element 141. The magnetic conductor 131 is magnetically attracted by the magnetic element 141, causing the carrier 120 to move closer to the magnetic element 141. The coil 132 corresponds to the magnetic element 141 and is adapted to generate a magnetic field, interacting with the magnetic force of the magnetic element 141, thereby causing the carrier 120 to move along the incident light direction LD. The magnetic sensing element 133 can be a Hall sensor, disposed corresponding to the coil 132 to sense changes in the magnetic field of the magnetic element 141, thereby calculating the relative position of the carrier 120.

Specifically, when the magnitude and direction of the current in coil 132 change, the magnetic force generated by coil 132 will also change accordingly. The magnetic force generated by coil 132 interacts with the magnetic force of magnetic component 141, thereby causing the carrier 120 to move up and down relative to magnetic component 141 and housing 110 along the incident light direction LD.

Furthermore, as shown in Figures 3, 4B, and 5, the lens module 100 of this embodiment also includes a plurality of sliders 170 located between the upright portion 121 and the bracket 1121. The upright portion 121 includes a plurality of receiving slots 123 for accommodating the sliders 170. The bracket 1121 includes a plurality of guide rails 1124 corresponding to the sliders 170. The sliders 170 are located in the plurality of receiving slots 123 and the plurality of guide rails 1124. In this embodiment, the sliders 170 are, for example, ball bearings. However, in other embodiments, the sliders 170 may also be guide rods.

The magnetic conductor 131 is attracted by the magnetic component 141, which causes the carrier 120 to move closer to the magnetic component 141, so that the upright part 121 is supported by the bracket 1121 through multiple sliding members 170. When the magnetic force of the coil 132 changes, the upright part 121 slides on the guide rail 1124 of the bracket 1121 through multiple sliding members 170, thereby allowing the upright part 121 to move smoothly relative to the second drive assembly 140 and the housing 110 in the light incident direction LD.

It should be noted that although only one magnetic element 141 is shown in Figures 2 to 4B, multiple magnetic elements 141 can be provided according to actual needs. This invention does not limit the number of magnetic elements 141. Furthermore, in other embodiments, the first driving component 130 can be the magnetic element 141, and the second driving component 140 can include a magnetic conductor 131, a coil 132, and a magnetic sensing element 133. That is, the positions of the magnetic element 141, the magnetic conductor 131, the coil 132, and the magnetic sensing element 133 can be interchanged.

Similarly, although Figures 3 and 5 show four sliders 170 and four corresponding guide rails 1124, this invention does not limit the number of sliders 170 and guide rails 1124. It is only necessary to ensure that the number of sliders 170 corresponds to the number of guide rails 1124.

Figure 6 is a three-dimensional schematic diagram of the carrier, first drive assembly, transmission component, and image sensor of Figure 1. Figure 7 is a three-dimensional schematic diagram of the carrier and transmission component of Figure 1. Figure 8 is an external schematic diagram of the transmission component of Figure 1.

Referring to Figures 4A, 6 to 8, the camera module 100 of this embodiment further includes a transmission element 150 and an image sensor 160. The transmission element 150 is, for example, a flexible circuit board. The transmission element 150 extends from inside the housing 110 to outside the housing 110 and is located above the support portion 122. The transmission element 150 is electrically connected to the coil 132 of the first drive assembly 130, for example, through solder 182 and the circuit 134 inside the upright portion 121, so that the transmission element 150 can provide the current required by the coil 132.

An image sensor 160 is housed within a base 112 and positioned above a transmission element 150, with a lens 190 positioned above the image sensor 160. The image sensor 160 is electrically connected to the transmission element 150. The image sensor 160 is used to detect the intensity and color temperature of ambient light to automatically adjust the brightness and color performance of the incoming light. When ambient light passes through the lens 190 to the image sensor 160, the information detected by the image sensor 160 can be transmitted through the transmission element 150.

The transmission component 150 includes a movable part 151, two curved parts 152, and a fixed part 153 connected in sequence. The movable part 151 is housed within a base 112. The movable part 151 and the image sensor 160 are connected to and supported by a support part 122. The curved parts 152 are housed within the base 112. Each of the two curved parts 152 has its two ends connected to the movable part 151 and the fixed part 153, respectively, and the two curved parts 152 are symmetrically positioned on opposite sides of the movable part 151. Furthermore, the fixed part 153 has a gap d between it and the movable part 151 and is located away from the upright part 121. In other words, the movable part 151 and the fixed part 153 are not directly connected; they are connected through two curved parts 152.

Furthermore, the movable part 151 has a horizontal segment 1511 and a vertical segment 1512 that are vertically connected to the support part 122. The vertical segment 1512 is adjacent to the upright part 121, and the horizontal segment 1511 extends from the vertical segment 1512 in a direction away from the upright part 121. There are two spaces S between the horizontal segment 1511, the vertical segment 1512 and the fixed part 153 to accommodate the two curved parts 152. The two curved parts 152 extend curvedly within the two spaces S.

As shown in Figure 8, each of the two curved sections 152 has two curved lines 1521. The two curved lines 1521 first extend from one end of the horizontal section 1511 away from the fixed part 153 in a direction parallel to the horizontal section 1511, then approach the fixed part 153, then bend back 180 degrees and extend towards the vertical section 1512, then bend back 180 degrees and extend away from the vertical section 1512 towards the fixed part 153. This process of extension and bending back and forth is repeated in space S. The two curved sections 152 bend back and forth four times between the horizontal section 1511 and the vertical section 1512 and the fixed part 153, and extend away from the horizontal section 1511, finally connecting to the fixed part 153.

By designing the two curved sections 152 to bend back and forth between the straight section 1512 and the fixed section 153, the total length of the two curved sections 152 can be increased, thereby ensuring that the current during the movement of the movable section 151 is less than the current that the coil 132 can handle, so that the movable section 151 and the image sensor 160 can be smoothly moved by the support section 122 of the carrier 120 relative to the housing 110 along the light-incident direction LD.

In other embodiments, the two curved portions 152 may each have only one curve 1521 or more than two curves 1521. This invention does not limit the number of curves 1521. Furthermore, the bending manner of the two curves 1521 is not limited in the manner described above. As long as the length of the two curved portions 152 is sufficiently long to allow current to pass smoothly through the curved portions 152 and be successfully electrically connected to the first drive assembly 130, it is acceptable.

Furthermore, the fixing part 153 of this embodiment has a connecting section 1531 and an extension section 1532 that are interconnected. The connecting section 1531 is located inside the housing 110 and is directly connected to the two curved parts 152. The extension section 1532 is located outside the housing 110 and is connected to a connecting part 154. External components (such as the circuit board of a mobile phone) can be electrically connected to the transmission component 150 and the coil 132 through the connecting part 154 to provide the current required by the coil 132, and the information sensed by the image sensor 160 can also be transmitted to the external components through the transmission component 150 and the connecting part 154.

In this embodiment, the vertical projection of the lateral segment 1511 onto the image sensor 160 passes through the center 161 of the image sensor 160. When the carrier 120 moves along the incident light direction LD, the movable part 151 is moved up and down by the support part 122, and the lateral segment 1511 moves the image sensor 160 up and down, thereby adjusting the imaging focal length. That is, this invention achieves the focusing effect by displacing the image sensor 160. Through the above design, the process of the lateral segment 1511 moving the image sensor 160 up and down will not cause the image sensor 160 to tilt due to the weight shift of the image sensor 160, thus not affecting the imaging quality.

Furthermore, as shown in Figure 6, the vertical projections of the two curved portions 152 onto the bottom surface 1123 of the housing 110 do not overlap with the vertical projections of the support portion 122 onto the bottom surface 1123. When the carrier 120 moves along the incident light direction LD, the movable portion 151 is moved up and down by the support portion 122. One end of the two curved portions 152 connected to the movable portion 151 is moved up and down by the movable portion 151, while the other end of the two curved portions 152 connected to the fixed portion 153 does not move relative to the base 112. In other words, the two curved portions 152 can provide vertical deformation extension, so that the fixed portion 153 and the connecting portion 154 will not move up and down with it, and the stability of the electrical connection between the connecting portion 154 and the external components will not be affected.

Furthermore, the area of the two curved portions 152 is greater than 70% of the total area of the two curved portions 152, the movable portion 151, and the connecting section 1531, and the stiffness (elasticity coefficient) of the transmission element 150 is less than 90 mN/mm. Through this design, it can be ensured that when the carrier 120 drives the movable portion 151 to move along the incident light direction LD, the two curved portions 152 provide sufficient deformation extension, so that the carrier 120 and the movable portion 151 are not restrained by the two curved portions 152, causing the image sensor 160 to produce unexpected distortion and affecting the imaging quality of the lens module 100. In addition, this design also ensures that the current during the movement of the movable part 151 is less than the current that the coil 132 can handle, so that the carrier 120, the movable part 151 and the image sensor 160 can move smoothly relative to the housing 110.

Figure 9 is an exploded view of the transmission component, circuit board, solder, and primer of Figure 1. Referring to Figures 2 and 9, the camera module 100 of this embodiment further includes a circuit board 181, two passive components 186, a solder 182, and a primer 183. The two passive components 186 are disposed on the circuit board 181. The circuit board 181 is disposed between the image sensor 160 and the transmission component 150 and electrically connects the image sensor 160 and the transmission component 150. In detail, the solder 182 and the primer 183 connect the circuit board 181 and the movable part 151 of the transmission component 150, so that the image sensor 160 is electrically connected to the transmission component 150 through the circuit board 181.

The lens module 100 of this embodiment also includes a metal plate 184 disposed between the support portion 122 and the back cover 1122. The metal plate 184 can strengthen the material strength of the support portion 122 to prevent deformation caused by insufficient material strength of the support portion 122 when the support portion 122 drives the movable portion 151, circuit board 181 and image sensor 160 above it, thereby affecting the image quality.

Furthermore, the lens module 100 of this embodiment also includes a filter 185 located between the lens 190 and the image sensor 160. The filter 185 can filter the infrared light passing through the lens 190 to restore the true color of the object and improve the image quality. The filter 185 can be, for example, blue glass (BG), but this invention is not limited thereto.

Based on the above, the lens module 100 of this embodiment, through the mutual influence of the magnetic forces of the coil 132 and the magnetic component 141, enables the first driving component 130 to drive the carrier 120 to move relative to the second driving component 140 and relative to the housing 110 along the light-incident direction LD. With this design, the lens module 100 of this embodiment does not require additional fixing components, thus reducing the overall height and weight of the lens module 100.

Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component designations and some content of the aforementioned embodiments, employing the same designations to represent the same or similar components, and omitting descriptions of identical technical content. The different features of each embodiment can, in principle, be applied to other embodiments. For explanations of the omitted parts, please refer to the aforementioned embodiments; they will not be repeated in the following embodiments.

Figure 10 is a schematic view of the appearance of a transmission member according to another embodiment of the present utility model. Referring to Figure 10, the transmission member 150a of the present embodiment is similar to the transmission member 150, the difference being that the bending method of the bent portion 152a of the present embodiment is different from the bending method of the bent portion 152.

Specifically, the curved portion 152a of this embodiment has two curved lines 1521a. The two curved lines 1521a first extend from the end of the transverse segment 1511 away from the fixed portion 153 along a direction parallel to the straight segment 1512 to the end near the straight segment 1512, then bend back 180 degrees and extend towards the transverse segment 1511, then bend back 180 degrees and extend away from the transverse segment 1511 to the end near the straight segment 1512. In this way, they extend and bend back repeatedly in space S’. The two curved sections 152a bend back and forth nine times between the horizontal section 1511 and the vertical section 1512 and the fixed section 153, and extend away from the vertical section 1512, and finally connect to the fixed section 153.

Figure 11 is a schematic view of the appearance of a transmission member according to another embodiment of the present utility model. Referring to Figure 11, the transmission member 150b of the present embodiment is similar to the transmission member 150, except that the bending method of the bent portion 152b of the present embodiment is different from the bending method of the bent portion 152, and the two bent portions 152b of the present embodiment each have only one curve 1521b.

Specifically, the curve 1521b first extends from the end of the straight section 1512 away from the horizontal section 1511 along a direction parallel to the horizontal section 1511, then near the fixing part 153, then bends vertically towards the horizontal section 1511, then bends vertically towards the straight section 1512, then bends vertically away from the horizontal section 1511, and so on, repeatedly extending in space S’’ and bending vertically towards the center A of each of the two spaces S’’. The two curved parts 152b bend vertically nine times from the straight section 1512 towards the center A of each of the two spaces S’’, and then bends vertically ten times away from the center A, finally connecting to the fixing part 153.

Similarly, the number of bends 1521a and 1521b is not limited in this invention. Furthermore, the bending manner of the bends 1521a and 1521b is not limited in the manner described above. As long as the length of the two bends 152a and 152b is sufficiently long to allow current to flow smoothly through the bends 152a and 152b and be successfully electrically connected to the first drive assembly 130, it is acceptable.

In summary, the lens module 100 of this invention, through the mutual influence of the magnetic forces of the coil 132 and the magnetic component 141, enables the first driving component 130 to drive the carrier component 120 to move relative to the second driving component 140 and relative to the housing 110 along the incident light direction LD. Through this design, the lens module 100 of this invention does not require additional fixing components, thus reducing the overall height and weight of the lens module 100.

Furthermore, the area of the two curved portions 152, 152a, and 152b in this novel invention is greater than 70% of the total area of the two curved portions 152, 152a, and 152b, the movable portion 151, and the connecting section 1531, and the stiffness of the transmission components 150, 150a, and 150b is less than 90 mN/mm. Through this design, it can be ensured that when the carrier 120 drives the movable portion 151 to move along the incident light direction LD, the carrier 120 and the movable portion 151 will not be restrained by the two curved portions 152, 152a, and 152b, thus affecting the imaging quality of the lens module 100, and the carrier 120, the movable portion 151, and the image sensor 160 can move smoothly relative to the housing 110.
