[0002] The lens mount is used for fixing the lens and driving the lens to move. The lens mount can cooperate with the limiting structure inside the lens module to limit the moving range of the lens. During the contact between the lens mount and the limiting structure, the limiting structure will generate an impact force on the lens mount, causing the lens mount to deform or be damaged. However, directly increasing the overall thickness of the lens mount to improve the structural strength of the lens mount will cause excessive occupation of the internal space of the lens module, and the movement of the lens mount will also interfere with the internal components.

In the following detailed description of the present invention, certain specific details are described in detail. Those skilled in the art will fully understand the present invention even without these details. To avoid obscuring the essence of the present invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0083] Figure 1 and Figure 2 This is a schematic diagram of the lens assembly in this embodiment.

[0084] In some implementations, such as Figures 1-2 As shown, the lens assembly in this embodiment includes a lens mounting base 1, an elastic part 2 disposed on the lens mounting base 1, a lens 3, and a drive coil 6. The lens assembly in this embodiment can be disposed within a lens module, and the drive coil 6 drives the lens mounting base 1 to move along the axial direction of the lens 3.

[0085] Figure 3 This is an exploded view of the lens assembly in this embodiment. Figure 4 and Figure 5 This is a schematic diagram of the lens mounting bracket 1 in this embodiment.

[0086] In some implementations, such as Figures 3-5 As shown, the lens mount 1 in this embodiment includes a body 11, a stop 12, and a reinforcing part 13. The body 11 is used to mount the lens 3, and under the drive of the body 11, the lens 3 can move along the optical axis, thereby adjusting the focal length. The body 11 is provided with a mounting surface 111 perpendicular to the axis of the lens 3, and the reinforcing part 13 includes a first reinforcing layer 41.

[0087] Specifically, in this embodiment, the body 11 has a mounting hole 113, and the lens 3 is fixed in the mounting hole 113. The orientation of the mounting surface 111 is consistent with that of the lens 3.

[0088] Figure 6 and Figure 7 This is a schematic diagram of the elastic part 2 in this embodiment. The area where the elastic part 2 is located is shown with cross-sectional lines (no cross-sectional lines are provided for the hollow area 5).

[0089] In some implementations, such as Figure 6 and Figure 7 As shown, the elastic part 2 includes a first connecting area 21 and a second connecting area 22. The elastic part 2 has a hollow area 5. This hollow area 5 can reduce the weight of the elastic part 2 and increase the deformation of the elastic part 2.

[0090] Specifically, the elastic part 2 is configured as a sheet-like structure. The elastic part 2 also includes an elastic connector 23. The elastic connector 23 is connected between the first connecting area 21 and the second connecting area 22, or the elastic connector 23 is connected between the two second connecting areas 22. The first connecting area 21 is used to connect with the lens mounting base 1, and the second connecting area 22 is used to connect with the inner area of ​​the lens module, so that the lens assembly can be suspended on the inner side of the lens module.

[0091] Further reference Figure 1 andFigure 4 As shown, the stop portion 12 and the first reinforcing layer 41 protrude from the fabric surface 111, and a portion of the stop portion 12 extends from the hollow area 5. The first connecting area 21 is fixedly connected to the body 11. Thus, the lens mount 1 can be suspended inside the lens module via the elastic portion 2. When the drive coil 6 drives the lens mount 1 to move, the elastic portion 2 generates a restoring force to drive the lens mount 1 to return to its original position. The reinforcing portion 13 is used to improve the structural strength between the body 11 and the stop portion 12, preventing deformation of the body 11 during repeated collisions between the stop portion 12 and the limiting surface 72 inside the housing 7. The first reinforcing layer 41 is configured to extend on the fabric surface 111. The thickness of the first reinforcing layer 41 can be configured to be 0.01mm to 0.05mm. Those skilled in the art can select the thickness based on the material of the lens mount 1 and the impact force provided by the drive coil 6 (e.g., 0.02mm).

[0092] Figure 8 This is a schematic diagram showing the positional relationship between the lens mount 1 and the elastic part 2 in this embodiment. The outline of the elastic part 2 and the leader line corresponding to the reference numerals of the elastic part 2 are shown in the figure with dashed lines.

[0093] Further reference Figures 6-8 As shown, the first reinforcing layer 41 extends from the stop portion 12 towards the edge of the fabric surface 111. Simultaneously, in a direction perpendicular to the fabric surface 111, the first reinforcing layer 41 is located inside the hollow area 5, meaning the first reinforcing layer 41 is positioned opposite to the hollow area 5. In this embodiment, the first reinforcing layer 41 improves the structural strength of the lens mount 1 and limits its area, preventing it from contacting the elastic portion 2 during the upward movement of the lens mount 1. When the stop portion 12 abuts against the limiting surface 72, a gap still exists between the fabric surface 111 and the elastic portion 2.

[0094] In summary, in this embodiment, the lens assembly has the elastic part 2 and the lens 3 mounted on the lens mounting base 1. The first connecting area 21 of the elastic part 2 is fixedly connected to the lens mounting base 1, and the second connecting area 22 is fixedly connected to the inner area of ​​the lens module, so that the lens mounting base 1 is hung inside the lens module. Simultaneously, the stop part 12 can limit the movement distance of the lens 3 within the lens module. Therefore, the stop part 12 is configured to extend from the hollow area 5, allowing it to avoid the elastic part 2. Furthermore, the first reinforcing layer 41 is disposed between the stop part 12 and the edge of the fabric surface 111, which can specifically improve the mechanical strength of the edge of the body 11. This prevents damage to the lens mounting base 1 and the edge of the body 11 from tilting upwards towards the fabric surface 111 during prolonged use. On the other hand, the elastic part 2 will bend and deform during the upward movement of the lens mounting base 1. Therefore, the first reinforcing layer 41 is configured to be opposite to the hollow area 5, so that the first reinforcing layer 41 can avoid the elastic part 2 and prevent the first reinforcing layer 41 from colliding with the elastic part 2.

[0095] Figure 9 This is a partial schematic diagram of the body 11 provided in the first embodiment of this utility model. The area where the second reinforcing layer 42 is located is shown by cross-sectional lines in the figure.

[0096] In some implementations, such as Figure 4 and Figure 9 As shown, the stop portion 12 includes a fixed boss 121 and a stop body 122. The fixed boss 121 protrudes from the fabric surface 111, and the first connecting area 21 is fixedly connected to the platform of the fixed boss 121, that is, the first connecting area 21 is installed on the top of the fixed boss 121. Further referencing... Figure 8 As shown, the stop body 122 protrudes from the platform of the fixed boss 121 and is offset from the first connecting area 21. The stop body 122 is configured to pass through the hollow area 5, the protrusion height of the reinforcing part 13 is less than or equal to the protrusion height of the fixed boss 121, and the first reinforcing layer 41 is connected to the side wall of the fixed boss 121. Specifically, the top surface of the first reinforcing layer 41 is configured as a plane and parallel to the laying surface 111.

[0097] In this embodiment, the fixed boss 121 increases the distance between the elastic part 2 and the fabric surface 111, allowing the elastic connector 23 sufficient deformation space when the lens mount 1 moves. However, stress concentration can occur at the connection point between the fixed boss 121 and the fabric surface 111. Therefore, a first reinforcing layer 41 is disposed between the fixed boss 121 and the fabric surface 111 to improve the structural strength of the fixed boss 121 and the fabric surface 111.

[0098] Figure 10 This is a partial schematic diagram of the body 11 provided in the second embodiment of this utility model.

[0099] In some implementations, such as Figures 6-7 As shown, the elastic part 2 in this embodiment also includes an elastic connector 23. The elastic connector 23 includes a plurality of first elastic arms 231, and a plurality of second connecting areas 22 extending laterally toward the lens mount 1. Two adjacent second connecting areas 22 are connected by the first elastic arms 231, and at least part of the hollow area 5 is formed between the first elastic arms 231 and the first connecting areas 21. A portion of the first elastic arm 231 is positioned opposite to the edge of the body 11.

[0100] Further reference Figure 8 and Figure 10 As shown, the stop body 122 includes a first stop body 1221, and there are multiple first stop bodies 1221, which are correspondingly arranged with at least a portion of the first elastic arms 231. The first reinforcing layer 41 has a first side 411, which is located on the side of the first reinforcing layer 41 away from the fixed boss 121, and at least a portion of the first side 411 is parallel to and spaced apart from the corresponding first elastic arms 231.

[0101] In this embodiment, when the lens mounting base 1 approaches the first elastic arm 231, the first side 411 and the first elastic arm 231 are at a predetermined distance in the extending direction of the laying surface 111. This prevents the first reinforcing layer 41 from contacting the first elastic arm 231.

[0102] In some implementations, such as Figure 5 As shown, the surface 111 is a polygonal plane with multiple first sides 1111. The fixing boss 121 includes multiple first fixing blocks 1211, which are correspondingly arranged with the multiple first sides 1111. Further referencing... Figure 9 As shown, the first fixing block 1211 has a first connecting surface 1213 and two second connecting surfaces 1214 facing both sides of the first connecting surface 1213. The first connecting surface 1213 is parallel to the corresponding first edge 1111. Further referencing... Figure 10 As shown, the first reinforcing layer 41 also has two second sides 412 corresponding to the two second connecting surfaces 1214. The second sides 412 extend in a straight line from the second connecting surfaces 1214 to the edge of the polygonal plane. The ends of the two second sides 412 that are away from the first fixing block 1211 are far away from each other and connected to the two ends of the first side 411.

[0103] In this embodiment, the ends of the two second sides 412 that connect to the first side 411 are open, and the two ends of the two second sides 412 are symmetrical with respect to the first fixing block 1211. This maximizes the mechanical strength between the first fixing block 1211 and the body 11, given the limited surface area 111 of the first reinforcing layer 41. Specifically, the length of the first reinforcing layer 41 can be configured to be 1.35 mm.

[0104] In some implementations, such as Figures 1-4 As shown, the lens assembly also includes a drive coil 6. The body 11 has a coil groove 112 facing the lens mount 1, and the inner wall of the coil groove 112 has a second side surface 1121, which faces the opposite direction to the mounting surface 111 and corresponds to at least part of the reinforcement 13.

[0105] Figure 11 This is a partial schematic diagram of the body 11 provided in the third embodiment of this utility model. The positional relationship between the first elastic arm 231 and the second reinforcing layer 42, shown by the dotted line in the figure, is the position when the stop part 12 abuts against the limiting structure in the lens module.

[0106] In some implementations, such as Figures 9-10 As shown, the reinforcing part 13 also includes a second reinforcing layer 42 protruding from the laying surface 111. The second reinforcing layer 42 includes a first extension 421. One side of the first extension 421 is connected to the second side 412, and the other side is inclined toward and connected to the laying surface 111.

[0107] In this embodiment, the first extension 421 can increase the volume of the reinforcing part 13, and the first extension 421 can be configured to be opposite to a portion of the second elastic arm 232 (e.g., Figure 7 (As shown in region I). Therefore, the inclined first extension 421 can avoid contact with the second elastic arm 232, preventing the second elastic arm 232 from coming into contact with the first extension 421.

[0108] Furthermore, such as Figures 6-7 As shown, the elastic connector 23 also includes a plurality of second elastic arms 232 corresponding to a plurality of second connection areas 22. One end of the second elastic arm 232 is connected to the corresponding second connection area 22, and the other end is connected to the first connection area 21. The second elastic arms 232 are disposed in the hollow area 5, and a portion of the second elastic arms 232 is opposite to a portion of the first extension segment 421.

[0109] In some implementations, such as Figure 9As shown, the second reinforcing layer 42 includes a second extension 422, which corresponds to the first elastic arm 231. One side of the second extension 422 is connected to the first side edge 411, and the other side is inclined towards and connected to the laying surface 111 to avoid the first elastic arm 231. Optionally, the inclination angle of the second reinforcing layer 42 is 10° (e.g., ...). Figure 11 (As shown at angle a2). Therefore, by using the inclined second extension 422, the first elastic arm 231 can be avoided, preventing the first elastic arm 231 from contacting the first extension 421 when the elastic part 2 deforms (as shown in angle a2). Figure 11 (As shown).

[0110] In some implementations, such as Figure 4 and Figure 6 As shown, the body 11 has a mounting hole 113, and the lens 3 is disposed in the mounting hole 113. The first connecting area 21 includes an annular body 25, and the inner edge of the annular body 25 forms a clearance hole 24 corresponding to the mounting hole 113, through which the lens 3 extends. In this embodiment, the annular body 25 can increase the contact area between the elastic part 2 and the lens mounting seat 1, so that when the elastic part 2 drives the lens mounting seat 1 to reset, the lens mounting seat 1 can move along the axial direction of the lens 3.

[0111] In some implementations, such as Figure 6 As shown, the second elastic arm 232 is bent and extended, and its end is connected to the outer edge of the annular body 25.

[0112] Preferably, the ends of the plurality of second elastic arms 232 that connect to the annular body 25 are evenly distributed along the circumference of the annular body 25. This simplifies the shape of the first connection area 21 while ensuring the consistency of the reset driving force acting on the lens mount 1 in all directions.

[0113] In some implementations, such as Figure 7 As shown, the first connecting area 21 also includes a connecting piece 26. The connecting piece 26 extends from the outer edge of the annular body 25, and a plurality of second elastic arms 232 extend and bend, with their ends connected to the connecting piece 26. Thus, the connecting piece 26 can further increase the contact area between the first connecting area 21 and the lens mount 1. Furthermore, the same connecting piece 26 can simultaneously connect multiple second elastic arms 232.

[0114] Specifically, there are two connecting pieces 26, which are symmetrically arranged with respect to the center of the annular body 25. There are four first elastic arms 231, four second elastic arms 232, and four second connecting areas 22. The same connecting piece 26 is connected to two second elastic arms 232 simultaneously.

[0115] Furthermore, such as Figure 4As shown, the body 11 includes a central body 114 and two flanges 115, which extend laterally from the central body 114 toward the mounting hole 113. The two flanges 115 and the side of the central body 114 form the aforementioned coil groove 112. The two sides of one flange 115 are respectively used to form a second side surface 1121 and at least a partial mounting surface 111. In this embodiment, the drive coil 6 is wound around the body 11 through the coil groove 112. The lens module is also provided with a magnetic body. When the drive coil 6 is energized, it generates an induced magnetic field, which interacts with the magnetic force generated by the magnetic body, thereby driving the body 11 to move upward. During this process, the driving force of the drive coil 6 acts on the upper flange 115, causing the flange 115 to tilt upward. For this reason, in this embodiment, the two second side surfaces 412 can increase the mounting surface 111 of the first reinforcing layer 41 on the flange 115, thereby improving the mechanical strength of the flange 115. At the same time, as Figure 8 As shown, the second side 412 can also provide more deformation space for the second elastic arm 232.

[0116] In some implementations, such as Figure 12 As shown, the reinforcing part 13 also includes a third reinforcing layer 43. At least a portion of the third reinforcing layer 43 is disposed on the top of the first reinforcing layer 41 and extends along the side wall of the fixing boss 121. In this embodiment, the third reinforcing layer 43 can increase the thickness of the reinforcing part 13, thereby further improving the mechanical strength of the body 11 and the fixing boss 121. Furthermore, the third reinforcing layer 43 corresponds to the hollow area 5, thereby avoiding interference with the elastic part 2.

[0117] Figure 13 yes Figure 12 A cross-sectional view of the reinforcing portion 13 at the middle BB in some embodiments. Figure 14 yes Figure 12 Cross-sectional view of the reinforcement portion 13 at BB in some other embodiments.

[0118] In some implementations, such as Figure 13 and Figure 14 As shown, the third reinforcing layer 43 has a first side surface 431. One side of the first side surface 431 is connected to the fixed boss 121, and the other side is connected to the top of the first reinforcing layer 41. The first side surface 431 is either curved or flat.

[0119] Further reference Figure 13 As shown, the cross-sectional shape of the arc surface in the extension direction is a circular arc with a radius of 0.06mm to 0.12mm.

[0120] Optionally, the radius of the arc can be 0.06mm, 0.08mm, 0.10mm, or 0.12mm. By configuring the first side 431 as a rounded corner, the manufacturing process of the lens mount 1 can be optimized, improving product quality.

[0121] Further reference Figure 14 As shown, the side of the plane that connects to the first reinforcing layer 41 is inclined towards the laying surface 111, and the inclination angle is 10° to 25° (e.g., Figure 14 (as shown by angle a1 in the diagram).

[0122] Optionally, the tilt angle of the plane can be 10°, 15°, 20°, and 25°. The tilt amplitude of the first side 431 can be selected according to the magnitude of the impact force and the height of the fixed boss 121.

[0123] Figure 15 This is a partial schematic diagram of the body 11 provided in the fourth embodiment of this utility model.

[0124] In some implementations, such as Figure 15 As shown, the lengths of the first reinforcing layer 41 and the second reinforcing layer 42 used to reinforce the first fixing block 1211 and the body 11 can be selected according to the magnitude of the impact force generated by the drive coil 6. For example, the first reinforcing layer 41 can be positioned between the two second stops 1222, with a length of 0.45 mm. Alternatively, the length of the first reinforcing layer 41 can be the same as the length of the first fixing block 1211, which can be 0.9 mm. Yet another example is that the two ends of the first reinforcing layer 41 can be positioned on both sides of the second fixing block 1212 and extend along the edge of the fabric surface 111, with a length of 2.7 mm.

[0125] Figure 16 This is a partial schematic diagram of the body 11 provided in the fifth embodiment of this utility model. Figure 17 This is a partial schematic diagram of the body 11 provided in the sixth embodiment of this utility model. Figure 18 This is a partial schematic diagram of the body 11 provided in the ninth embodiment of this utility model.

[0126] In some implementations, such as Figure 5 As shown, the surface 111 is a hexagonal plane, with two parallel first sides 1111. The hexagonal plane also includes two parallel second sides 1112, which are perpendicular to the first sides 1111 and have a length greater than the first sides 1111. Further reference... Figures 16-18 As shown, the fixed boss 121 also includes two second fixing blocks 1212, which correspond to the two second sides 1112 respectively. The stop body 122 also includes two pairs of second stop bodies 1222, each pair of second stop bodies 1222 being disposed on the two second fixing blocks 1212. The two second stop bodies 1222 of the same second fixing block 1212 are spaced apart. One side of the first reinforcing layer 41 is connected to the second fixing block 1212, and the other side extends toward the second side 1112.

[0127] Specifically, the first stop 1221 and the second stop 1222 are at the same height. This allows the first stop 1221 and the second stop 1222 to simultaneously abut against the limiting structure, thereby ensuring that the axis of the lens 3 always coincides with the optical axis. In this embodiment, the body 11 and the stop 12 are reinforced by the reinforcing part 13 in both the length direction of the first side 1111 and the length direction of the second side 1112, thereby improving the overall strength of the lens mounting base 1.

[0128] Furthermore, such as Figure 16 As shown, the second reinforcing layer 42 in the above embodiment can be disposed along the edge of the first reinforcing layer 41 to increase the strength between the second fixing block 1212 and the body 11.

[0129] Furthermore, such as Figure 17 As shown, the third reinforcing layer 43 in the above embodiment can be disposed between the first reinforcing layer 41 and the second fixing block 1212 to further increase the strength between the second fixing block 1212 and the body 11.

[0130] Figure 19 This is a partial schematic diagram of the body 11 provided in the tenth embodiment of this utility model.

[0131] In some implementations, such as Figure 19 As shown, the length of the first reinforcing layer 41 used to reinforce the second fixing block 1212 and the body 11 can be selected according to the magnitude of the impact force generated by the drive coil 6. For example, the first reinforcing layer 41 can be positioned between the two second stops 1222, and its length can be configured to be 0.9 mm or 1.8 mm. Alternatively, the two ends of the first reinforcing layer 41 can be positioned on both sides of the second fixing block 1212 and extend along the edge of the fabric surface 111. Its length can be configured to be 2.7 mm, 3.6 mm, 4.5 mm, or longer.

[0132] Figure 20 This is a schematic diagram of the shell structure in this embodiment.

[0133] In one alternative implementation, such as Figures 1-20 As shown, the lens assembly in the above embodiment can be applied to a lens module. The lens module also includes a housing 7. The housing 7 has a mounting cavity 71, and the mounting cavity 71 has a limiting surface 72. The lens assembly moves towards the limiting surface 72 under the drive of the drive coil 6. When the stop part 12 abuts against the limiting surface 72, the elastic part 2 elastically deforms and generates a reset force. Thus, when the power supply to the drive coil 6 is stopped, the elastic part 2 can promptly drive the lens mounting base 1 to reset.

[0134] In summary, in this embodiment, the lens module has the elastic part 2 and the lens 3 mounted on the lens mounting base 1. The first connecting area 21 of the elastic part 2 is fixedly connected to the lens mounting base 1, and the second connecting area 22 is fixedly connected to the inner area of ​​the lens module, so that the lens mounting base 1 is hung inside the lens module. Simultaneously, the stop part 12 can limit the movement distance of the lens 3 within the lens module. Therefore, the stop part 12 is configured to extend from the hollow area 5, allowing it to avoid the elastic part 2. Furthermore, the first reinforcing layer 41 is disposed between the stop part 12 and the edge of the mounting surface 111, which can specifically improve the mechanical strength of the edge of the body 11. This prevents damage to the lens mounting base 1 and the edge of the body 11 from tilting upwards towards the mounting surface 111 during prolonged use. On the other hand, the elastic part 2 will bend and deform during the upward movement of the lens mounting base 1. Therefore, the first reinforcing layer 41 is configured to be opposite to the hollow area 5, so that the first reinforcing layer 41 can avoid the elastic part 2 and prevent the first reinforcing layer 41 from colliding with the elastic part 2.

[0135] Figure 21 This is a stress simulation diagram of the lens mount 1 in this embodiment. The simulation result shows the stress distribution of the stop portion 12 when subjected to an impact force of 25KG and 0.08 milliseconds, with the first side surface 431 configured as a plane. Simulation results A, B, C, and D in the figure are the simulation results when the first side surface 431 is tilted at 25°, 20°, 15°, and 10°, respectively. As can be seen from the figure, the maximum pressures of simulation results A, B, C, and D are 87.68Mpa, 82.97Mpa, 79.50Mpa, and 89.58Mpa, respectively.

[0136] Therefore, the first side 431 can be configured as a plane with an inclination angle of 15°. In this configuration, the third reinforcing layer 43 can improve its impact resistance and prevent impact stress from concentrating at the bottom of the fixed boss 121.

Various modifications and variations can be made to this utility model by those skilled in the art.
