[0051] In order to better understand the technical content of the present invention, preferred specific embodiments are described below.

[0052] Figure 1 This is a schematic diagram of an image acquisition device according to a first embodiment of the present invention. Figure 2 for Figure 1 Please refer to the exploded diagram of the lens module shown in the figure. Figure 1 and Figure 2 In this embodiment, the image acquisition device 1 includes a housing 10 and a lens module 20. The housing 10 is the outer shell of the image acquisition device 1, and the lens module 20 is disposed in the housing 10. Figure 1 As shown. The image acquisition device 1 of this embodiment takes a camera that can be placed on a flat surface (such as a desktop) as an example. The housing 10 also has a base 11 and a head 12 for accommodating the housing 10, and the lens module 20 is located in the head 12 of the housing 10. The lens module 20 includes a lens body 21, a clamping assembly 22 and a buffer 23. The lens body 21 is the main structure of the lens module 20. The lens body 21 is disposed in the clamping assembly 22 and is connected to the housing 10 by the clamping assembly 22, so that the lens body 21 does not contact the housing 10. In other words, the lens module 20 is connected to the housing 10 through the clamping assembly 22, and the lens body 21 is located in the clamping assembly 22 and does not contact the housing 10.

[0053] like Figure 2 As shown, the lens body 21 includes at least one first connecting portion 211. The first connecting portion 211 is provided on the outer surface 210 of the lens body 21. In this embodiment, the lens body 21 includes a plurality of first connecting portions 211. Figure 2 For example, the first connecting portion 211 is located on the outer surface 210 of the upper side and the lower side of the lens body 21. Figure 2 The first connecting portion 211 shown on the lower side of the lens body 21 is obscured and not depicted. Correspondingly, the clamping assembly 22 includes at least one second connecting portion 221, and the position of the second connecting portion 221 corresponds to the position of the first connecting portion 211. Therefore, the clamping assembly 22 also includes multiple second connecting portions 221, which correspond to the first connecting portions 211 on the upper and lower sides of the lens body 21, respectively.

[0054] Preferably, the clamping assembly 22 of this embodiment includes a first clamping member 222 and a second clamping member 223. The clamping assembly 22 includes a plurality of second connecting portions 221, which are respectively disposed on the first clamping member 222 and the second clamping member 223. Figure 2For example, the first clamping member 222 of this embodiment is an L-shaped member having a flat portion 2221 facing the upper side of the lens body 21 and an upright portion 2222 facing the right sidewall of the lens body 21. The second clamping member 223 has a flat portion 2231 facing the lower side of the lens body 21 and a bent portion 2232 facing the right sidewall of the lens body 21. The second connecting portions 221 are located on the flat portion 2221 of the first clamping member 222 and the flat portion 2231 of the second clamping member 223, respectively, to correspond to the first connecting portions 211 located on the upper and lower sides of the lens body 21.

[0055] Furthermore, the first clamping member 222 and the second clamping member 223 are fixed to each other to form the clamping assembly 22. Figure 1 As shown, the first clamping member 222 of this embodiment further includes a hook 2223 located on a side of the upright portion 2222. Correspondingly, the second clamping member 223 includes a slot 2233 extending from the edge of the bent portion 2232 toward the first clamping member 222 (i.e., upward). After the first clamping member 222 and the second clamping member 223 are disposed on the outer surface 210 of the lens body 21, the hook 2223 engages with the slot 2233, thereby connecting and securing the first clamping member 222 and the second clamping member 223 to form the clamping assembly 22, with the lens body 21 positioned within the clamping assembly 22. In other embodiments, the first clamping member 222 may include a slot, while the second clamping member 223 may include a corresponding hook. The first clamping member 222 and the second clamping member 223 may still be secured by the engagement of the hook and slot, but this is not a limitation of the present invention.

[0056] Figure 3 for Figure 1 The image acquisition device is shown as a cross-sectional diagram along line AA. Figure 4 for Figure 2 For an enlarged schematic diagram of the buffer shown, please refer to Figure 2 、 Figure 3 and Figure 4 As shown. The buffer member 23 of this embodiment is arranged between the first connecting portion 211 and the second connecting portion 221, so that the buffer member 23 covers at least a portion of the first connecting portion 211 and at least a portion of the second connecting portion 221. In addition, the first connecting portion 211 can be fixed to each other through the buffer member 23 and the second connecting portion 221. Specifically, the first connecting portion 211 of this embodiment is a column, and is preferably a cylindrical body. The second connecting portion 221 is a groove body or a perforation, and is preferably a circular groove body or a circular perforation. In addition, the buffer member 23 of this embodiment is a cap structure, which has an accommodating space 231, as shown Figure 3Preferably, the buffer member 23 includes a circular top 232, a sidewall portion 233, and an annular bottom 234. The opposite ends of the sidewall portion 233 are connected to the circular top 232 and the annular bottom 234, respectively. Furthermore, the sidewall portion 233 is located around the outer periphery of the circular top 232 and on the inner edge of the annular bottom 234, forming a circular cap structure for the buffer member 23.

[0057] The buffer member 23 can be sleeved on the outside of the first connection portion 211, and the first connection portion 211 and the buffer member 23 can be accommodated in the second connection portion 221. Figure 4 When assembling the lens module 20, the accommodating space 231 of the buffer 23 can be aligned with the first connecting portion 211, so that the buffer 23 is sleeved on the outside of the first connecting portion 211 (i.e., the cylinder). In this embodiment, the first connecting portion 211 includes a top 2111 and a side wall 2112. Figure 3 The buffer member 23 covers the top portion 2111 and the side wall portion 2112 near the top portion 2111. When the buffer member 23 is sleeved on the first connection portion 211, the circular top portion 232 and the side wall portion 233 are sleeved on the outside of the first connection portion 211.

[0058] Next, the flat portion 2221 of the first clamping member 222 and the flat portion 2231 of the second clamping member 223 are aligned with the upper and lower sides of the lens body 21, respectively. The buffer member 23 is inserted into the second connecting portion 221 (i.e., the circular groove or circular perforation), so that the buffer member 23 is accommodated within the second connecting portion 221. At this point, the circular top portion 232 and a portion of the sidewall portion 233 of the buffer member 23 are accommodated within the second connecting portion 221, and the outer surface 235 of the buffer member 23 interferes with the inner wall 2211 of the second connecting portion 221. Therefore, the first connecting portion 211 is secured by the interlocking engagement between the buffer member 23 and the second connecting portion 221. In other embodiments, the first connecting portion 211, the second connecting portion 221, and the buffer member 23 may be secured by bonding or locking. Preferably, the first connecting portion 211, the second connecting portion 221, and the buffer member 23 of this embodiment are coaxially arranged. In other words, the centers of the first connection portion 211 , the second connection portion 221 and the circular top portion 232 of the buffer 23 are located on the same straight line, so that the first connection portion 211 , the second connection portion 221 and the buffer 23 are coaxially arranged.

[0059] Preferably, the buffer member 23 of this embodiment includes at least one protrusion 236, which is provided on the outer surface 235 of the buffer member 23. The buffer member 23 of this embodiment includes a plurality of protrusions 236, which are provided at intervals on the side wall portion 233. In addition, the protrusion 236 and the axial direction of the circular top 232 are parallel to each other. Specifically, the axial direction of the circular top 232 is a direction passing through the center of the circular top 232 and perpendicular to the circular top 232. Correspondingly, the protrusion 236 is also perpendicular to the circular top 232, so that the axial directions of the protrusion 236 and the axial direction of the circular top 232 are parallel to each other. In other words, the protrusions 236 are radially arranged on the side wall portion 233. When the buffer member 23 is located in the second connecting portion 221, the protrusion 236 interferes with the inner wall 2211 of the second connecting portion 221, as shown in FIG. Figure 3 Preferably, the convex portion 236 of this embodiment is not only provided on the outer side of the side wall portion 233, but also extends from the side wall portion 233 to the annular bottom portion 234, as shown. Figure 4 shown.

[0060] Finally, the first clamping member 222 and the second clamping member 223 are fixed to each other, for example, they are buckled together, so that the lens body 21 is located between the first clamping member 222 and the second clamping member 223. The housing 10 is connected to the clamping assembly 22 and does not contact the lens body 21. In addition, the lens body 21 and the clamping assembly 22 are fixed to each other by the buffer 23. In addition, the buffer 23 is a soft material, which can be, for example, but not limited to rubber or silicone. When the lens module 20 adjusts the focal length, the motor inside the lens body 21 runs and causes vibration. When the vibration is transmitted to the buffer 23, the buffer 23 can be compressed or elastically deformed by the pressure without affecting the clamping assembly 22 and the housing 10, thereby absorbing shock and reducing noise through the buffer 23. Specifically, since the buffer member 23 is located between the first connecting portion 211 of the lens body 21 and the second connecting portion 221 of the clamping assembly 22, it can absorb the vibration of the first connecting portion 211 caused by the operation of the motor and prevent the first connecting portion 211 and the second connecting portion 221 from colliding with each other and generating noise. In this embodiment, the top 2111 of the first connecting portion 211 and the bottom outer edge 2212 of the second connecting portion 221 are located on the same horizontal plane. Figure 3 That is, the top portion 2111 of the first connection portion 211 extends into the second connection portion 221 without the buffer 23, thereby enhancing the noise reduction effect. In other embodiments, the top portion 2111 of the first connection portion 211 may also extend into the second connection portion 221 together with the buffer 23, and the present invention is not limited thereto.

[0061] Figure 5 This is a schematic diagram of a buffer member according to the second embodiment of the present invention. Figure 5As shown. The buffer 23a of this embodiment also includes an accommodating space (not shown), a circular top 232a, a side wall portion 233a, an annular bottom 234a and a plurality of protrusions 236a. The difference from the buffer 23 of the aforementioned embodiment lies in the structure of the protrusion 236a. The protrusion 236a of this embodiment is arranged on the side wall portion 233a and is parallel to the circumference of the circular top 232a. Specifically, the circumference of the circular top 232a is the circumferential direction of the circular top 232a. The protrusion 236a surrounds the side wall portion 233a, so that the protrusion 236a and the circumference of the circular top 232a are parallel to each other to form an annular protrusion 236a. In addition, the buffer 23 in the first embodiment can also replace the buffer 23a of this embodiment to be sleeved on the first connecting portion 211 (please refer to Figure 3 As shown), and is provided on the second connecting portion 221 (please refer to Figure 3 At this time, the protrusion 236a can also interfere with the inner wall 2211 of the second connection part 221, thereby achieving the effects of fixing the first connection part 211 and the second connection part 221, reducing vibration and noise.

[0062] Figure 6 is a schematic diagram of an image acquisition device according to a third embodiment of the present invention. Figure 7 for Figure 6 The schematic diagram of the lens module shown is Figure 8 for Figure 7 Please refer to the exploded diagram of the lens module shown in Figure 6 、 Figure 7 and Figure 8 As shown. The image acquisition device 1b of this embodiment takes a handheld camera as an example, which also includes a housing 10b and a lens module 20b, but the appearance of the housing 10b is different from the appearance of the housing 10 of the first embodiment. The lens module 20b of this embodiment is also arranged in the housing 10b. The lens module 20b also includes a lens body 21b, a clamping assembly 22b and a buffer 23. Among them, the structure of the buffer 23 is the same as that of the first embodiment, so its element number is used. In addition, the buffer 23a of the second embodiment can also be applied to the lens module 20b of this embodiment. In other words, the buffer 23 can also be replaced with the buffer 23a of the second embodiment.

[0063] like Figure 8As shown, the lens body 21b also includes a first connecting portion 211b, and the first connecting portion 211b of this embodiment is also a circular cylinder and is arranged on the outer surface 210b of the upper and lower sides of the lens body 21b. The clamping assembly 22b is connected to the housing 10b. The clamping assembly 22b of this embodiment also includes a first clamping member 222b and a second clamping member 223b. The first clamping member 222b and the second clamping member 223b are fixed to each other to jointly form the clamping assembly 22b. Among them, the clamping assembly 22b also includes a plurality of second connecting portions 221b, and the second connecting portions 221b of this embodiment are also circular grooves or perforations. The second connecting portions 221b are respectively arranged on the first clamping member 222b and the second clamping member 223b.

[0064] by Figure 8 For example, the first clamping member 222b of this embodiment is an L-shaped member having a planar portion 2221b facing the upper side of the lens body 21b and an upright portion 2222b facing the side wall of the lens body 21b. The second clamping member 223b is an elongated strip-shaped structure. The second connecting portion 221b is located on the planar portion 2221b of the first clamping member 222b and the second clamping member 223b, respectively, so that the position of the second connecting portion 221b corresponds to the position of the first connecting portion 211b. Similarly, the buffer member 23 is mounted on the outside of the first connecting portion 211b, and the second connecting portion 221b is aligned with the buffer member 23 and accommodated within the second connecting portion 221b. In this case, the buffer member 23 covers at least a portion of the first connecting portion 211b and at least a portion of the second connecting portion 221b. Furthermore, since the buffer member 23 and the second connection portion 221 b interfere with each other, the first connection portion 211 b and the second connection portion 221 b are fixed to each other through the buffer member 23 .

[0065] Similarly, the first clamping member 222b also includes a hook 2223b, which is located on the surface of the upright portion 2222b. The second clamping member 223b has a corresponding slot 2233b. The slot 2233b is located on the side edge of the second clamping member 223b and extends toward the first clamping member 222b. After the first clamping member 222b and the second clamping member 223b are placed on the outer surface 210b of the lens body 21b, the hook 2223b and the slot 2233b are interlocked to form a clamping assembly 22b. At this time, the lens body 21b is located between the first clamping member 222b and the second clamping member 223b. In addition, the housing 10b is connected to the clamping assembly 22b so that the housing 10b and the lens body 21b are not in direct contact. When the lens module 20b adjusts the focal length, the motor inside the lens body 21b runs and causes vibration. At this time, the buffer member 23 can be compressed or elastically deformed by the pressure, thereby absorbing shock and reducing noise through the buffer member 23. Preferably, the lens module 20b of this embodiment further includes a noise reduction structure 24b, such as Figure 8As shown. The noise reduction structure 24b is provided on the upright portion 2222b of the first clamping member 222b and is located on the surface of the upright portion 2222b facing the lens body 21b. For example, the noise reduction structure 24b of this embodiment can be fixed to the upright portion 2222b by bonding or spot welding. In addition, the noise reduction structure 24b is also made of a soft material with elasticity, which can be, for example, but not limited to, rubber, silicone or foam. When the first clamping member 222b is placed on the outer surface 210b of the lens body 21b, the noise reduction structure 24b fits the outer surface 210b of the lens body 21b, thereby achieving the effect of absorbing shock and reducing noise during motor operation.

[0066] Figure 9 is a schematic diagram of a lens module according to a fourth embodiment of the present invention. Figure 10 for Figure 9 The exploded diagram of the lens module shown is Figure 11 for Figure 9 Please refer to the cross-sectional diagram of the lens module shown at line BB. Figure 9 、 Figure 10 and Figure 11 As shown. The lens module 20c of this embodiment also includes a lens body 21c, a clamping assembly 22b, and a buffer member 23c. The structure of the clamping assembly 22b is the same as that of the third embodiment, and therefore its component numbers are retained. The clamping assembly 22b also includes a first clamping member 222b and a second clamping member 223b that can be fixed to each other, and the lens body 21c is disposed between the first clamping member 222b and the second clamping member 223b. It should be noted that the connection method between the clamping assembly 22b and the lens body 21c can refer to the third embodiment. The difference from the aforementioned embodiment lies in the structure of the first connecting portion 211c of the lens body 21c, which is the same as the second connecting portion 221b of the clamping assembly 22b, and can both be circular grooves or circular through-holes. In this embodiment, the first connecting portion 211c is a circular groove, while the second connecting portion 221b is a circular through-hole. Similarly, the second connecting portion 221b is located on the first clamping member 222b and the second clamping member 223b, respectively. In other embodiments, the first connection portion 211 c may be a circular through-hole, and the second connection portion 221 b may be a circular groove, but the present invention is not limited thereto.

[0067] Furthermore, the buffer member 23c of this embodiment is a circular cylinder, preferably a circular solid cylinder. Specifically, the buffer member 23c of this embodiment includes a side wall portion 233c and a plurality of protrusions 236c. The protrusions 236c are arranged at intervals on the side wall portion 233c, and the protrusions 236c and the circumferential direction of the buffer member 23c are parallel to each other. In other words, the protrusions 236c surround the side wall portion 233c of the buffer member 23c, so that the protrusions 236c are arranged in a ring shape on the side wall portion 233c, as shown in FIG. Figure 10In other embodiments, the protrusions 236c may also be parallel to the axial direction of the buffer member 23c, so that the protrusions 236c are radially arranged on the sidewall portion 233c, and the present invention is not limited thereto.

[0068] When assembling the lens module 20c, one end of the buffer member 23c can be first placed on the first connecting portion 211c of the lens body 21c. The first and second clamping members 222b, 223b can then be positioned on the outer surface 210c of the lens body 21c, with the other end of the buffer member 23c positioned within the second connecting portion 221b. In other embodiments, the assembly can be reversed, for example, by first placing one end of the buffer member 23c on the second connecting portion 221b of the clamping assembly 22b. The first and second clamping members 222b, 223b can then be positioned on the outer surface 210c of the lens body 21c, with the other end of the buffer member 23c positioned within the first connecting portion 211c of the lens body 21c. In this case, the buffer member 23c is positioned within the first and second connecting portions 211c, 221b, and covers both the first and second connecting portions 211c, 221b. Furthermore, the protrusion 236c interferes with the inner walls of the first and second connecting portions 211c, 221b, securing the first and second connecting portions 211c, 221b, via the buffer 23c. Furthermore, when the lens module 20b adjusts its focus, the motor inside the lens body 21b operates, causing vibrations. This vibration is absorbed by the buffer 23c, reducing noise.

[0069] In summary, according to the image acquisition device and lens module thereof of the present invention, the lens module includes a lens body, a clamping assembly and a buffer. The clamping assembly is connected to the housing of the image acquisition device, and the lens body is disposed within the clamping assembly. The buffer covers at least a portion of the first connecting portion and at least a portion of the second connecting portion, so that the first connecting portion can be fixed to the second connecting portion through the buffer. Since the housing is connected to the clamping assembly, and the lens body and the clamping assembly are fixed to each other through the buffer. When the lens module adjusts the focal length, the buffer can prevent the first connecting portion and the second connecting portion from colliding with each other and generating noise, thereby achieving the effect of shock absorption and noise reduction.
