Description
Technical Field
[0001] The invention provides an image capturing device, in particular to an image capturing module with dustproof function. Background Art
[0002] With the development of camera technology, cameras are increasingly used in various environments, and the requirements for photographic performance are becoming higher and higher. When using a camera, it is often difficult to avoid the intrusion of dust or water, especially when the camera lens is a zoom lens. During the zooming process, dust can easily be sucked into the lens with the movement of the lens structure and the flow of air, which will not only affect the image quality of the camera, but also cause wear and damage to the internal mechanism of the camera lens.
[0003] If the camera lens used is replaceable or disassembled, the user can clean and maintain the lens when dust or water invades the camera lens. However, if the camera lens used is not replaceable and is a fixed lens built into the electronic device, the user cannot directly clean the dust or water inside the lens, thus affecting the normal service life and performance stability of the camera.

[0098] refer to Figures 1 to 3 , Figure 1 is a cross-sectional view of an image capture device according to an embodiment, Figure 2 yes Figure 1 A cross-sectional view from another perspective of the embodiment, Figure 3 FIG. 1 is a cross-sectional view of an image capture device according to another embodiment. The image capture device comprises a bracket 10, a housing 12, an actuator module 14, an elastic member 16, a focus module 18, a focus module 20, a sensor module 22 and an anti-shake module 24. The bracket 10 has a bracket surface 101 and an opening 103. The opening 103 has a plurality of axially extending portions (e.g., Figure 1The housing 12 is disposed on the support surface 101, and a side of the housing 12 away from the support surface 101 has a window 121 and a waterproof ring 123, wherein the window 121 has a second ring wall 122 extending in the axial direction, and the waterproof ring 123 is disposed on the second ring wall 122.
[0099] The actuator module 14 is disposed on the bracket 10 and is located in the housing 12. The elastic member 16 has a first end 161 and a second end 163 opposite to each other, and the first end 161 abuts against the bracket 10. The focus module 18 is located in the housing 12, and includes a first surface 181, a second surface 183 and a third annular wall 185 parallel to the axial direction. The third annular wall 185 is perpendicular to the first annular wall 105 in a radial direction (such as Figure 1 The focusing module 18 at least partially overlaps on the X-axis shown in the figure, and the second surface 183 of the focusing module 18 abuts against the second end 163 of the elastic member 16, and the focusing module 18 can be elastically displaced along the axial direction.
[0100] The focus module 20 is located in the housing 12, and includes an upper surface 201, a lower surface 203 and a fourth ring wall 205 parallel to the axial direction. The waterproof ring 123 located on the second ring wall 122 abuts against the fourth ring wall 205. The focus module 20 faces the first surface 181 of the focus module 18 with the lower surface 203, and the focus module 20 is connected to the actuating module 14 so that the actuating module 14 can actuate the focus module 20 to move.
[0101] refer to Figure 4 and Figure 5 , Figure 4 is a side view of an image capture device according to an embodiment, showing that the focus module is located at a first position. Figure 5 It is a side view of an image capture device according to another embodiment, showing that the focus module is located at the second position. The actuator module 14 drives the focus module 20 to move axially between the first position P1 and the second position P2. When the focus module 20 is located at the second position P2, the lower surface 203 of the focus module 20 is in contact with the first surface 181 of the focus module 18 and the focus module 18 compresses the elastic member 16. When the focus module 20 is located at the first position P1, the lower surface 203 of the focus module 20 is separated from the first surface 181 of the focus module 18.
[0102] In some embodiments, the fixed focus module 18 and the focusing module 20 respectively have an optical axis, and the optical axis of the fixed focus module 18 and the optical axis of the focusing module 20 are aligned with each other to form an optical axis of the image capture device. The direction of the optical axis of the image capture device is the axial direction, and the perpendicular optical axis is the radial direction.
[0103] Refer to Figure 2 , Figure 3The sensing module 22 is disposed on a side of the bracket 10 different from the bracket surface 101. The optical axis of the sensing module 22 can be aligned with the optical axes of the focusing module 18 and the focusing module 20, and is used to capture the light passing through the focusing module 20 and the focusing module 20 to achieve the effect of the image capture device photography. The anti-shake module 24 is connected to the sensing module 22. When the user has hand tremors or other similar conditions when using the image capture device, the anti-shake module 24 can actuate the movement of the sensing module 22 on a plane perpendicular to the axis, thereby offsetting the hand tremors.
[0104] In some embodiments, the housing 12 has an upper shell surface 125, and the window 121 is located on the upper shell surface 125 and can penetrate the upper shell surface 125. The shape and radial size of the window 121 can correspond to the position of the focusing module 20 near the upper shell surface 125 (for example, Figure 2 The focus module 20 shown is exposed outside the housing 12 and has a radial size, so that a portion of the focus module 20 can pass through the window 121.
[0105] In some embodiments, the opening 103 passes through the bracket 10, and the shape and radial size of the opening 103 may correspond to the shape and radial size of the fourth ring wall 205 of the focusing module 18, so as to allow a portion of the focusing module 18 to pass through. At the same time, the opening 103 of the bracket 10 provides a space for accommodating the focusing module 18.
[0106] Refer to Figure 4 In some embodiments, when the focus module 20 is at the first position P1, it is the position farthest from the bracket 10. In this state, a portion of the focus module 20 is exposed to the housing 12 through the window 121, the lower surface 203 of the focus module 20 and the first surface 181 of the focus module 18 are separated from each other, and the third annular wall 185 and the first annular wall 105 have a small overlap in the radial direction.
[0107] refer to Figure 5 In other embodiments, when the focus module 20 is at the second position P2, it is the position where the focus module 20 is closest to the bracket 10. In this state, the lower surface 203 of the focus module 20 is in contact with the first surface 181 of the focus module 18, so that the focus module 18 compresses the elastic member 16 and passes through the opening 103, and the third annular wall 185 and the first annular wall 105 overlap more in the radial direction. At the same time, the focus module 20 is located in the housing 12 and is not exposed to the housing 12.
[0108] refer to Figure 6 , Figure 61 is a side view of an image capture device according to another embodiment, showing that the focus module is located at a third position. In some embodiments, there is a third position P3 between the first position P1 and the second position P2. During the process of the actuation module 14 actuating the focus module 20 to move axially from the first position P1 to the second position P2, when the lower surface 203 of the focus module 20 abuts against the first surface 181 of the focus module 18 and the elastic member 16 has not been compressed, the position of the focus module 20 is the third position P3.
[0109] Refer to Figures 2 to 6 When the actuating module 14 actuates the focusing module 20 to move between the first position P1 and the third position P3, since the lower surface 203 of the focusing module 20 is separated from the first surface 181 of the focusing module 18 or happens to be in contact with the first surface 181 and does not press against the focusing module 18 to move axially, the axial position of the focusing module 18 is maintained at the fourth position P4, wherein the fourth position P4 is between the second position P2 and the bracket 10, and at this time, the radially overlapping portion of the third annular wall 185 and the first annular wall 105 is small.
[0110] refer to Figure 7 and Figure 8 , Figure 7 yes Figure 2 A three-dimensional schematic diagram of an image capture device according to an embodiment of the present invention, Figure 8 yes Figure 3 A three-dimensional schematic diagram of an image capture device of an embodiment. As shown in the embodiment in the figure, when the focus module 20 is displaced, a portion of it will pass through the window 121 and be located outside the housing 12, or will be displaced from the window 121 and enter the housing 12. In some embodiments, when the focus module 20 is completely located inside the housing 12, the risk of scratching or other damage to the focus module 20 can be reduced, and the possibility of dust accumulation on the focus module 20 can be reduced. When the focus module 20 is located at different positions in the axial direction, the image capture device will have different focal lengths and can be used for photography at multiple focal lengths. Furthermore, when the focus module 20 is located at the second position P2, the size of the image capture device can be reduced.
[0111] However, in some embodiments, there is a gap between the second ring wall 122 of the window 121 and the fourth ring wall 205 of the focusing module 20 to prevent the focusing module 20 from generating friction with the fourth ring wall 205 during the displacement process, thereby affecting the displacement of the focusing module 20. When the focusing module 20 moves from the outside of the window 121 into the housing 12, the gap may allow dust or water outside the image capture device to enter the interior of the image capture device along with the displacement of the focusing module 20. Therefore, during the period when the focusing module 20 moves between the first position P1 and the third position P3, the waterproof ring 123 located on the second ring wall 122 of the window 121 abuts against the fourth ring wall 205 of the focusing module 20, and along with the displacement of the focusing module 20, the waterproof ring 123 abuts against different positions in the fourth ring wall 205, so as to prevent external dust or water from having the opportunity to enter the image capture device from between the second ring wall 122 and the fourth ring wall 205, thereby avoiding causing dirt inside the image capture device.
[0112] In some embodiments, the waterproof ring 123 may be formed of a high molecular material with elasticity, such as silicone, rubber or foam, etc. However, when the focus module 20 is displaced along the axial direction, the position of the waterproof ring 123 against the fourth ring wall 205 changes accordingly, and the waterproof ring 123 will not be excessively deformed and damaged due to the friction between the waterproof ring 123 and the fourth ring wall 205, or cause difficulty in the displacement of the focus module 20.
[0113] Refer to Figures 2 to 6 In some embodiments, the elastic member 16 is a compression spring. When the elastic member 16 is subjected to force, the elastic member 16 can be compressed and accumulate elastic force, and release the elastic force to restore the initial state when the force disappears. When the actuating module 14 actuates the focus module 20 to move from the third position P3 to the second position P2, the focus module 20 begins to press against the fixed focus module 18 to move toward the bracket 10. The focus module 20 applies force to the elastic member 16 through the fixed focus module 18, and the elastic member 16 is compressed by the force. The first end 161 of the elastic member 16 is fixed to the bracket 10 and remains stationary, and the second end 163 approaches the first end 161. At this time, the axial position of the fixed focus module 18 will gradually change from the fourth position P4 to the fifth position P5 as the focus module 20 presses against it. The fifth position P5 is between the fourth position P4 and the bracket 10. At the fifth position P5, the fixed focus module 18 can no longer move to a position closer to the bracket 10.
[0114] During the displacement of the focus module 18 from the fourth position P4 to the fifth position P5, the focus module 18 gradually passes through the opening 103, so that the radially overlapping portion of the third annular wall 185 and the first annular wall 105 gradually increases with the displacement. In some cases, dust or water may still enter the image capture device and contaminate the focus module 18, the sensor module 22, etc. in the image capture device. The more radially overlapping portions of the first annular wall 105 and the third annular wall 185 are, the more dust from the outside can be prevented from falling on the focus module 18 or the sensor module 22, thereby effectively reducing the influence of dust on the imaging of the image capture device, and making it difficult for water to enter the focus module 18 or the sensor module 22, so as to better maintain the photographic performance of the image capture device.
[0115] In some embodiments, a distance is allowed between the first annular wall 105 and the third annular wall 185 to prevent the friction between the first annular wall 105 and the third annular wall 185 from causing wear on the opening 103 of the focusing module 18 or the bracket 10 when the focusing module 18 is displaced. However, the smaller the distance, the more effective it is to prevent dust from falling on the sensing module 22.
[0116] In some embodiments, when the actuating module 14 actuates the focusing module 20 to move from the second position P2 to the third position P3, the force generated by the focusing module 20 on the elastic member 16 gradually decreases. In this state, the elastic member 16 releases its elastic force, so that the second end 163 of the elastic member 16 gradually moves away from the first end 161, and the focusing module 18 is displaced between the fifth position P5 and the fourth position P4 as the elastic force of the elastic member 16 is released. When the focusing module 20 moves to the second position P2, the elastic member 16 returns to the state before being compressed, and the axial position of the focusing module 18 returns to the fourth position P4. At this time, the radially overlapping portion of the third annular wall 185 and the first annular wall 105 gradually decreases with the displacement.
[0117] refer to Fig. 9 and Fig.10 , Fig. 9 and Fig.10 In some embodiments, the bracket 10 includes a groove 107, the groove 107 surrounds the opening 103, and the elastic member 16 can be disposed in the groove 107. Specifically, the first end 161 of the elastic member 16 is disposed on the inner side of the bracket 10 and the second end 163 of the elastic member 16 abuts against the second surface 183 of the focus module 18 when the focus module 18 is located at the fourth position P4 (refer to Figure 4 When the lower surface 203 of the focusing module 20 is pressed against the first surface 181 of the focusing module 18, the elastic member 16 is compressed to make the second end 163 close to the groove 107. The elastic member 16 can be implemented by a spring (such as Figure 2 As shown), a solid structure may also be formed by elastic polymer materials such as silicone, rubber or foam.
[0118] In an embodiment in which the elastic member 16 is a solid structure, a local cross-sectional shape of the elastic member 16 is the same as a shape of the groove 107 so as to fill the groove 107. When the elastic member 16 is in a state before being compressed, the solid structure between the first end 161 and the second end 163 can form a closed space through the space between the first end 161 and the second end 163 and the inner side of the focusing module 18 and the sensing module 22, and can also prevent external dust from falling into the focusing module 18 or on the sensing module 22.
[0119] In some embodiments, by radially overlapping the first annular wall 105 and the third annular wall 185, partially filling the groove 107 with the solid elastic member 16, and forming a closed space between the focusing module 18 and the sensing module 22, better waterproof and dustproof effects can be achieved. When external dust falls onto the sensing module 22, it must first pass through the solid elastic member 16 and the path formed by the radial overlap between the first annular wall 105 and the third annular wall 185, which greatly increases the difficulty.
[0120] refer to Fig.11 , 12 and Fig.13 , Fig.11 and Fig.12 are cross-sectional views of an image capture device according to yet another embodiment, Fig.13 yes Fig.11 In some embodiments, the image capture device further includes a dustproof structure 26, and the dustproof structure 26 is used to prevent dust or water from entering the focusing module 20 or the sensing module 22.
[0121] The dustproof structure 26 may be located between the first annular wall 105 of the bracket 10 and the third annular wall 185 of the focusing module 18 , and forms a closed space between the focusing module 18 and the sensing module 22 to achieve a waterproof and dustproof effect.
[0122] The dustproof structure 26 includes a first cover 261 and a second cover 265. The first cover 261 has a first cover body 262 and a first cover edge 263 connected to each other. The first cover body 262 extends axially and penetrates the first annular wall 105. The first cover edge 263 extends radially toward the center of the opening 103.
[0123] The second cover body 265 has a second cover body 266, a second cover edge 267 and a third cover edge 268 connected to each other, the second cover body 266 extends axially and is sleeved outside the focus module 18, the second cover edge 267 extends radially in a direction away from the first annular wall 105 and is located between the second surface 183 of the focus module 18 and the second end 163 of the elastic member 16. The third cover edge 268 extends radially in a direction close to the first annular wall 105.
[0124] Among them, the first cover body 262 can be fitted with the first annular wall 105, and the second cover edge 267 can be fitted with the second surface 183. When the focusing module 20 is located at the first position P1, the fixed focus module 18 is located at the fourth position P4, and the first cover edge 263 is against the third cover edge 268. When the focusing module 20 moves from the third position P3 to the second position P2, the second cover body 265 moves toward the sensing module 22 as the fixed focus module 18 moves from the fourth position P4 to the fifth position P5. During the displacement process, the first cover edge 263 contacts different positions of the second cover body 266 as it moves, and the third cover edge 268 also contacts different positions of the first cover body 262 as it moves. In this way, the dust-proof structure 26 can effectively prevent dust or water from entering the fixed focus module 18 and the sensing module 22 during the displacement process of the fixed focus module 18.
[0125] In some embodiments, when the focusing module 18 is located at the fifth position P5, the first cover edge 263 of the first cover body 261 abuts against the second surface 183 of the focusing module 18, and the third cover edge 268 of the second cover body 265 abuts against the bracket 10, and the first cover body 262 and the second cover body 266 overlap radially.
[0126] In addition to the radial overlap between the waterproof ring 123, the first ring wall 105 and the third ring wall 185 and the solid elastic member 16 located in the groove 107, in some embodiments, waterproof glue 28 is used to connect the components in the image capture device to increase the waterproof and dustproof effect. Fig.12 The waterproof glue 28 can be applied but not limited to between the bracket 10 and the housing 12, and between the bracket 10 and the sensor module 22. In addition to achieving the effect of bonding these components to each other, the waterproof glue 28 can also prevent dust or water on the outside of the image capture device from entering the image capture device through the gaps between the components.
[0127] In some embodiments, the fixed-focus module 18 includes a fixed-focus frame 187 and a fixed-focus lens 189. The fixed-focus lens 189 is fixed on the fixed-focus frame 187. The fixed-focus lens 189 and the fixed-focus frame 187 can also be joined with a waterproof glue 28. For example, the adhesive for fixing can be arranged in the contact area between the fixed-focus frame 187 and the fixed-focus lens 189 by a dispensing method, and the fixed-focus lens 189 and the fixed-focus frame 187 are fixed by the adhesive.
[0128] Refer to Figure 2 , Fig. 9 or Fig.11 As mentioned above, the sensing module 22 is disposed on a side of the bracket 10 different from the bracket surface 101, and is used to capture light passing through the focusing module 20 and the focusing module 20 to achieve the effect of image capture device photography. In some embodiments, the sensing module 22 includes a circuit board 221, a sensing element 223 and a sensing frame 225, the sensing element 223 is connected to the circuit board 221, and the sensing frame 225 is disposed on the circuit board 221 and covers the sensing element 223. The sensing element 223 has a sensing optical axis, and the sensing optical axis is aligned with the optical axis of the focusing module 18 and the optical axis of the focusing module 20 to form the optical axis of the image capture device.
[0129] The bracket 10 can be set on the sensing frame 225, and the bracket 10 and the sensing frame 225 can also be joined by the aforementioned waterproof glue 28, so as to achieve the effect of integrating the sensing module 22 and the bracket 10 into an image capture device and preventing dust or water from entering the image capture device from there and the image sensing element 223 capturing light to form an image.
[0130] In some embodiments, the sensing element 223 may be a photosensitive device that converts photons into electronic signals, such as a CMOS photoreceptor (Complementary Metal-Oxide-Semiconductor), a CCD photoreceptor (Charge-Coupled Device), or a BSI photoreceptor (Back Side Illuminated).
[0131] refer to Fig.14 and Fig.15 , Fig.14 FIG. 1 is a top view of a sensing module and an anti-shake module according to an embodiment. Fig.15 for Fig.14 3D exploded view of the sensing module and the anti-shake module of the embodiment. In some embodiments, when the user experiences hand shaking or other similar conditions while using the image capture device, the anti-shake module 24 can actuate the sensing module 22 to move in a plane perpendicular to the axis, thereby counteracting the hand shaking.
[0132] Specifically, the anti-shake module 24 may include a first connecting member 241 and a driver 243. The driver 243 is arranged on the circuit board 221 of the sensing module 22. The sensing element 223 may be arranged on the driver 243 through the first connecting member 241, wherein the sensing element 223 is fixed to the first side 242a of the first connecting member 241 and fixed to the driver 243 with the second side 242b of the first connecting member 241.
[0133] In some embodiments, the driver 243 includes a fixed portion 244, a driving portion 245 and a movable portion 246. The driver 243 is attached to the circuit board 221 with the fixed portion 244, the movable portion 246 is located between the fixed portions 244 and connected to the fixed portions 244, and the driving portion 245 is located in the movable portion 246 and can drive the movable portion 246 to produce a displacement corresponding to hand shaking. The second side 242b of the first connecting member 241 is fixed to the driver 243 and is fixed to the movable portion 246. When the driving portion 245 drives the movable portion 246 to move, the sensing element 223 disposed above the driving portion 245 is displaced by the driven portion 245, thereby achieving the effect of anti-hand shaking.
[0134] In some embodiments, the movable part 246 can be divided into an inner side 246a and an outer side 246b by the driving part 245. When the driving part 245 drives the movable part 246 to move, the inner side 246a and the outer side 246b will be driven to move at the same time. However, when the second side 242b of the first connecting member 241 is fixed to the movable part 246, the first connecting member 241 can be fixed to the inner side 246a of the movable part 246 avoiding the position of the driving part 245. In this way, it can be avoided that when the first connecting member 241 is glued to the movable part 246, the glue or other gluing materials used are coated on the driving part 245, thereby affecting the displacement of the driving part 245. At the same time, by connecting the sensing element 223 and the movable part 246 through the first connecting member 241, it can also be avoided that when the sensing element 223 is directly glued to the movable part 246, the glue used is coated on the driving part 245, thereby affecting the displacement of the driving part 245.
[0135] In some embodiments, the driver 243 may be a micro electro mechanical system (MEMS) actuator, and the driving portion 245 is a comb drive (or armature) therein. The comb drive can generate linear displacement through the voltage applied by the circuit board 221, and this linear displacement can drive the movable portion 246 to move.
[0136] Since the fixed part 244 is fixed to the circuit board 221, the movable part 246 and the fixed part 244 can be connected by the cantilever 247. When the driving part 245 drives the movable part 246 to move, the cantilever 247 can generate corresponding extension or contraction to allow the movable part 246 to be connected to the fixed part 244 while still being able to move.
[0137] In some embodiments, a second connecting member 248 may be provided between the fixed portion 244 of the driver 243 and the circuit board 221. The fixed portion 244 and the circuit board 221 are connected via the second connecting member 248. The second connecting member 248 allows a distance to be provided between the driver 243 and the circuit board 221, so that when the driving portion 245 drives the movable portion 246 to displace, the movable portion 246 will not be affected by the fit with the circuit board 221.
[0138] In some embodiments, the driver 243 and the circuit board 221 and the sensing element 223 and the driver 243 can be electrically connected to each other by wire bonding (Wire Bonding) using wiring 249, so that the circuit board 221, the driver 243, and the sensing element 223 can both obtain power supply from the circuit board 221.
[0139] In some embodiments, the anti-shake module 24 may be implemented by a voice coil motor (VCM), a piezo electric motor or a shape memory alloy motor (SMA) in addition to being a micro piezoelectric system actuator.
[0140] In summary, the image capture device can be provided with different methods such as a waterproof ring 123, radial overlap between the first ring wall 105 and the third ring wall 185, and a solid elastic member 16 located in the groove 107 to achieve waterproof and dustproof effects, and the image capture device can have focal length adjustment through the displacement of the focus module 20, and the anti-shake module 24 can generate a displacement corresponding to the hand shake to achieve the anti-shake effect.
