Description

Technical Field

[0002] The lens mount is used to fix the lens and drive the lens to move. The lens mount can cooperate with the limiting structure inside the lens module to limit the movement range of the lens. During the contact between the lens mount and the limiting structure, the limiting structure will generate impact force on the lens mount, causing deformation or damage to the lens mount. 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 internal components.

[0083] Figure 1 and Figure 2 Schematic diagram of the structure of the lens assembly of this embodiment.

[0084] In some embodiments, Figure 1-Figure 2 As shown, the lens assembly in this embodiment includes a lens mounting seat 1, an elastic portion 2, a lens 3 and a driving coil 6 arranged on the lens mounting seat 1. The lens assembly in this embodiment can be arranged in a lens module, and the driving coil 6 is used to drive the lens mounting seat 1 to move along the axial direction of the lens 3.

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

[0086] In some embodiments, Figure 3-Figure 5 As shown, the lens mounting seat 1 in this embodiment includes a body 11, a stopper 12 and a reinforcement part 13. The body 11 is used to set the lens 3. Driven by the body 11, the lens 3 can move along the optical axis to adjust the focal length. The body 11 is provided with a layout surface 111 perpendicular to the axial direction of the lens 3, and the reinforcement part 13 includes a first reinforcement layer 41.

[0087] Specifically, the body 11 in this embodiment defines 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 2 is a schematic diagram of the structure of the elastic part 2 of this embodiment. In the figure, the area where the elastic part 2 is located is shown with a hatching line (the hollow area 5 is not provided with a hatching line).

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

[0090] Specifically, the elastic part 2 is configured as a sheet 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 two second connecting areas 22. The first connecting area 21 is used to connect with the lens mounting seat 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 and Figure 4As shown, the stopper 12 and the first reinforcement layer 41 are convexly arranged on the layout surface 111, and part of the stopper 12 extends from the hollow area 5, and the first connection area 21 is fixedly connected to the body 11. As a result, the lens mount 1 can be suspended on the inner side of the lens module through the elastic part 2. When the drive coil 6 drives the lens mount 1 to move, the elastic part 2 can generate a reset elastic force to drive the lens mount 1 to reset in time. The reinforcement part 13 is used to improve the structural strength between the body 11 and the stopper 12. Avoid the deformation of the body 11 during multiple collisions between the stopper 12 and the limiting surface 72 in the shell 7. The first reinforcement layer 41 is configured to extend on the layout surface 111. The thickness of the first reinforcement layer 41 can be configured to be 0.01mm to 0.05mm. Those skilled in the art can select (for example, 0.02mm) according to the material of the lens mount 1 and the impact force provided by the drive coil 6.

[0092] Figure 8 1 is a schematic diagram of the positional relationship between the lens mounting seat 1 and the elastic part 2 of this embodiment. In the figure, the outline of the elastic part 2 and the lead wires of the elastic part 2 corresponding to the reference numerals are shown with dotted lines.

[0093] Further reference Figure 6-Figure 8 As shown, the first reinforcing layer 41 extends from the stopper 12 to the edge of the layout surface 111. At the same time, in the direction perpendicular to the layout surface 111, the first reinforcing layer 41 is located inside the hollow area 5, that is, the first reinforcing layer 41 is arranged opposite to the hollow area 5. The first reinforcing layer 41 in this embodiment can improve the structural strength of the lens mounting seat 1, and limit the area of ​​the first reinforcing layer 41, so as to avoid the first reinforcing layer 41 from contacting with the elastic part 2 during the upward movement of the lens mounting seat 1. When the stopper 12 abuts against the limiting surface 72, there is still a gap between the layout surface 111 and the elastic part 2.

[0094] In summary, in the lens assembly of the present embodiment, the elastic part 2 and the lens 3 are arranged on the lens mounting seat 1, the first connection area 21 of the elastic part 2 is used to be fixedly connected to the lens mounting seat 1, and the second connection area 22 is used to be fixedly connected to the inner area of ​​the lens module, so that the lens mounting seat 1 is hung in the lens module. At the same time, the stopper 12 can also limit the moving distance of the lens 3 in the lens module. Therefore, the stopper 12 is configured to extend from the hollow area 5, so that the stopper 12 can avoid the elastic part 2. At the same time, the first reinforcement layer 41 is arranged between the stopper 12 and the edge of the layout surface 111, which can improve the mechanical strength of the edge position of the body 11 in a targeted manner. It is avoided that the lens mounting seat 1 is damaged during long-term use of the lens assembly, and the edge position of the body 11 is tilted above the layout surface 111. On the other hand, during the upward movement of the lens mounting seat 1, the elastic part 2 will bend and deform. To this end, the first reinforcing layer 41 is configured to be arranged opposite to the hollow area 5 so that the first reinforcing layer 41 can avoid the elastic part 2 to avoid collision between the first reinforcing layer 41 and the elastic part 2 .

[0095] Fig. 9 1 is a partial schematic diagram of the main body 11 provided in the first embodiment of the present invention. In the figure, the area where the second reinforcement layer 42 is located is shown by the section line.

[0096] In some embodiments, Figure 4 and Fig. 9 As shown, the stopper 12 includes a fixed boss 121 and a stopper body 122. The fixed boss 121 is convexly arranged on the layout surface 111, and the first connection area 21 is fixedly connected to the table surface of the fixed boss 121, that is, the first connection area 21 is installed on the top of the fixed boss 121. Figure 8 As shown, the stopper 122 is protruded from the table surface of the fixed boss 121 and is staggered with the first connection area 21. The stopper 122 is configured to pass through the hollow area 5, the protrusion height of the reinforcement portion 13 is less than or equal to the protrusion height of the fixed boss 121, and the first reinforcement layer 41 is connected to the side wall of the fixed boss 121. Specifically, the top surface of the first reinforcement layer 41 is configured as a plane and parallel to the layout surface 111.

[0097] The fixed boss 121 in this embodiment increases the distance between the elastic part 2 and the layout surface 111, so that the elastic connector 23 has sufficient deformation space when the lens mounting seat 1 moves. At the same time, the connection position between the fixed boss 121 and the layout surface 111 will produce stress concentration. For this reason, the first reinforcement layer 41 is arranged between the fixed boss 121 and the layout surface 111, which can improve the structural strength of the fixed boss 121 and the layout surface 111.

[0098] Fig.10 It is a partial schematic diagram of the main body 11 provided in the second embodiment of the present invention.

[0099] In some embodiments, Figure 6-Figure 7 As shown, the elastic part 2 in this embodiment further includes an elastic connector 23, which includes a plurality of first elastic arms 231. The number of second connection areas 22 is multiple and extends to the side of the lens mounting seat 1. Two adjacent second connection 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 connection areas 21. Part of the first elastic arm 231 is arranged opposite to the edge of the body 11.

[0100] Further reference Figure 8 and Fig.10 As shown, the stopper 122 includes a first stopper 1221, and the number of the first stopper 1221 is multiple and is arranged corresponding to at least part of the first elastic arm 231. The first reinforcement layer 41 has a first side 411, and the first side 411 is located on a side of the first reinforcement layer 41 away from the fixing boss 121, and at least part of the first side 411 is parallel to the corresponding first elastic arm 231 and is arranged at intervals.

[0101] In this embodiment, when the lens mounting seat 1 is close to the first elastic arm 231 , the first side edge 411 is at a predetermined distance from the first elastic arm 231 in the extending direction of the layout surface 111 , thereby avoiding contact between the first reinforcement layer 41 and the first elastic arm 231 .

[0102] In some embodiments, Figure 5 As shown, the layout surface 111 is a polygonal plane having a plurality of first sides 1111. The fixing boss 121 includes a plurality of first fixing blocks 1211, and the plurality of first fixing blocks 1211 are arranged correspondingly to the plurality of first sides 1111. Fig. 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, and the first connecting surface 1213 is parallel to the corresponding first edge 1111. Fig.10 As shown, the first reinforcement layer 41 also has two second side edges 412 corresponding to the two second connecting surfaces 1214. The second side edges 412 extend straight from the second connecting surfaces 1214 to the edge of the polygonal plane. The two second side edges 412 are away from one end of the first fixing block 1211 and are away from each other and connected to the two ends of the first side edges 411.

[0103] In this embodiment, the ends of the two second sides 412 connected 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. Therefore, under the premise that the layout surface 111 of the first reinforcement layer 41 is limited, the mechanical strength between the first fixing block 1211 and the body 11 is increased as much as possible. Specifically, the length of the first reinforcement layer 41 can be configured to be 1.35 mm.

[0104] In some embodiments, Figure 1-Figure 4 As shown, the lens assembly further includes a driving coil 6. The body 11 has a coil groove 112, the coil groove 112 faces the side of the lens mounting seat 1, and the inner wall of the coil groove 112 has a second side surface 1121, the second side surface 1121 faces the opposite direction of the layout surface 111 and corresponds to at least part of the reinforcement portion 13.

[0105] Fig.11 1 is a partial schematic diagram of the main body 11 provided by the third embodiment of the present invention. 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 stopper 12 abuts against the limiting structure in the lens module.

[0106] In some embodiments, Figure 9-10 As shown, the reinforcement portion 13 also includes a second reinforcement layer 42 protruding from the layout surface 111 , and the second reinforcement layer 42 includes a first extension section 421 , one side of the first extension section 421 is connected to the second side 412 , and the other side is inclined to and connected to the layout surface 111 .

[0107] In this embodiment, the first extension section 421 can increase the volume of the reinforcement portion 13, and the first extension section 421 can be configured to be opposite to a portion of the second elastic arm 232 (eg, Figure 7 Thus, the first extension section 421 arranged obliquely can avoid the second elastic arm 232 and prevent the second elastic arm 232 from contacting the first extension section 421.

[0108] Furthermore, if Figure 6-Figure 7 As shown, the elastic connector 23 further includes a plurality of second elastic arms 232 arranged corresponding to the 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 arm 232 is arranged in the hollow area 5, and part of the second elastic arm 232 is opposite to part of the first extension section 421.

[0109] In some embodiments, Fig. 9As shown, the second reinforcement layer 42 includes a second extension section 422, the second extension section 422 corresponds to the first elastic arm 231, one side of the second extension section 422 is connected to the first side edge 411, and the other side is inclined and connected to the layout surface 111 to avoid the first elastic arm 231. Optionally, the inclination angle of the second reinforcement layer 42 is 10° (such as Fig.11 Thus, the second extension section 422 arranged obliquely can avoid the first elastic arm 231, so as to prevent the first elastic arm 231 from contacting the first extension section 421 when the elastic part 2 is deformed (as shown in FIG. Fig.11 shown).

[0110] In some embodiments, Figure 4 and Figure 6 As shown, the body 11 has a mounting hole 113, and the lens 3 is arranged in the mounting hole 113. The first connection area 21 includes an annular body 25, and the inner edge of the annular body 25 forms an escape hole 24 corresponding to the mounting hole 113, and the lens 3 extends out from the escape hole 24. The annular body 25 in this embodiment 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 embodiments, Figure 6 As shown, the second elastic arm 232 extends in a bent manner and an end portion is connected to the outer edge of the annular body 25 .

[0112] Preferably, the ends of the plurality of second elastic arms 232 connected to the annular body 25 are evenly distributed along the circumference of the annular body 25. Thus, the shape of the first connecting area 21 is simplified, while ensuring the consistency of the reset driving force acting on the lens mounting seat 1 in all directions.

[0113] In some embodiments, Figure 7 As shown, the first connection area 21 further includes a connection piece 26. The connection piece 26 extends from the outer edge of the annular body 25, and a plurality of second elastic arms 232 are bent and extended, and the ends are connected to the connection piece 26. Thus, the connection piece 26 can further increase the contact area between the first connection area 21 and the lens mounting seat 1. In addition, the same connection piece 26 can be connected to a plurality of second elastic arms 232 at the same time.

[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. One connecting piece 26 is connected to two second elastic arms 232 at the same time.

[0115] Furthermore, if Figure 4As shown, the main body 11 includes a central body 114 and two flanges 115, and the two flanges 115 extend from the central body 114 to the side of the mounting hole 113. The two flanges 115 and the side of the central body 114 form the above-mentioned coil groove 112. The two sides of a flange 115 are respectively used to form a second side surface 1121 and at least a portion of the layout surface 111. The drive coil 6 in this embodiment is wound on the main body 11 through the coil groove 112. The lens module is also provided with a magnetic body. When the drive coil 6 is energized, an induced magnetic field is generated, which interacts with the magnetic force generated by the magnetic body, thereby driving the main body 11 to move upward. In this process, the driving force of the drive coil 6 will act on the flange 115 on the upper side, causing the flange 115 to tilt. To this end, the two second side edges 412 in this embodiment can increase the layout surface 111 of the first reinforcement 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 edge 412 can also leave more deformation space for the second elastic arm 232 .

[0116] In some embodiments, Fig.12 As shown, the reinforcing portion 13 further includes a third reinforcing layer 43. At least part 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. The third reinforcing layer 43 in this embodiment can increase the thickness of the reinforcing portion 13, so that the mechanical strength of the body 11 and the fixing boss 121 is further improved, and the third reinforcing layer 43 corresponds to the hollow area 5, so as to avoid mutual interference with the elastic portion 2.

[0118] In some embodiments, Fig.13 and Fig.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 fixing boss 121 , and the other side is connected to the top of the first reinforcing layer 41 . The first side surface 431 is a curved surface or a flat surface.

[0119] Further reference Fig.13 As shown, the cross-sectional shape of the arc surface in the extension direction is an arc, and the radius of the arc is 0.06 mm to 0.12 mm.

[0120] Optionally, the radius of the arc may be 0.06 mm, 0.08 mm, 0.10 mm or 0.12 mm. By configuring the first side surface 431 to be rounded, the manufacturing process of the lens mounting seat 1 can be optimized and the quality of the product can be improved.

[0121] Further reference Fig.14 As shown, the side of the plane connected to the first reinforcement layer 41 is inclined toward the layout surface 111, and the inclination angle is 10° to 25° (such as Fig.14 , as shown by angle a1 in FIG.

[0122] Optionally, the inclination angle of the plane may be 10°, 15°, 20°, or 25°. The inclination amplitude of the first side surface 431 may be selected according to the magnitude of the impact force and the height of the fixing boss 121 .

[0124] In some embodiments, Fig.15 As shown, the lengths of the first reinforcement layer 41 and the second reinforcement layer 42 used to reinforce the first fixed 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 reinforcement layer 41 is set between the two second stoppers 1222, and the length is configured to be 0.45mm. For another example, the length of the first reinforcement layer 41 is configured to be consistent with the length of the first fixed block 1211, and the length can be 0.9mm. For another example, the two ends of the first reinforcement layer 41 are set on both sides of the second fixed block 1212 and extend along the edge position of the layout surface 111, and the length can be 2.7mm.

Fig.17 It is a partial schematic diagram of the main body 11 provided in the sixth embodiment of the present invention. Fig.18 It is a partial schematic diagram of the main body 11 provided in the ninth embodiment of the present invention.

[0126] In some embodiments, Figure 5 As shown, the layout surface 111 is a hexagonal plane, and the number of first sides 1111 is two and they are parallel to each other. The hexagonal plane also includes two second sides 1112 that are parallel to each other, the second sides 1112 are perpendicular to the first sides 1111, and the length of the second sides 1112 is greater than the first sides 1111. Figure 16-18 As shown, the fixed boss 121 also includes two second fixed blocks 1212, and the two second fixed blocks 1212 correspond to the two second sides 1112 respectively. The stopper 122 also includes two pairs of second stoppers 1222, and each pair of second stoppers 1222 is respectively arranged on the two second fixed blocks 1212, and the two second stoppers 1222 of the same second fixed block 1212 are arranged at intervals, and one side of the first reinforcement layer 41 is connected to the second fixed block 1212, and the other side extends to the second side 1112.

[0127] Specifically, the first stopper 1221 and the second stopper 1222 have the same height, so that the first stopper 1221 and the second stopper 1222 can abut against the limit structure at the same time, thereby ensuring that the axis of the lens 3 always coincides with the optical axis. In this embodiment, the reinforcing part 13 is used to reinforce the body 11 and the stopper 12 in the length direction of the first side 1111 and the length direction of the second side 1112, so that the overall strength of the lens mounting seat 1 is improved.

[0128] Furthermore, if Fig.16 As shown, the second reinforcement layer 42 in the above embodiment can be arranged along the edge of the first reinforcement layer 41 to increase the strength between the second fixing block 1212 and the body 11 .

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

[0130] Fig.19 It is a partial schematic diagram of the main body 11 provided in the tenth embodiment of the present invention.

[0131] In some embodiments, Fig.19 As shown, the length of the first reinforcement 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 driving coil 6. For example, the first reinforcement layer 41 is set between the two second stoppers 1222, and the length configuration can be configured to be 0.9mm or 1.8mm. For another example, the two ends of the first reinforcement layer 41 are set on both sides of the second fixing block 1212 and extend along the edge position of the layout surface 111. Its length is configured to be 2.7mm, 3.6mm, 4.5mm or a longer distance.

[0132] Fig. 20 Schematic diagram of the structure of the shell of this embodiment.

[0133] In an optional implementation, if Figure 1-Figure 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 toward the limiting surface 72 under the drive of the drive coil 6, and when the stopper 12 abuts against the limiting surface 72, the elastic part 2 elastically deforms and generates a restoring elastic force. Therefore, when the power supply to the drive coil 6 stops, the elastic part 2 can promptly drive the lens mounting seat 1 to reset.

[0134] In summary, in the lens module of the present embodiment, the elastic part 2 and the lens 3 are arranged on the lens mounting seat 1, the first connection area 21 of the elastic part 2 is used to be fixedly connected with the lens mounting seat 1, and the second connection area 22 is used to be fixedly connected with the inner area of ​​the lens module, so that the lens mounting seat 1 is hung in the lens module. At the same time, the stopper 12 can also limit the moving distance of the lens 3 in the lens module. Therefore, the stopper 12 is configured to extend from the hollow area 5, so that the stopper 12 can avoid the elastic part 2. At the same time, the first reinforcement layer 41 is arranged between the stopper 12 and the edge of the layout surface 111, which can improve the mechanical strength of the edge position of the body 11 in a targeted manner. It is avoided that the lens mounting seat 1 is damaged during long-term use of the lens assembly, and the edge position of the body 11 is tilted above the layout surface 111. On the other hand, during the upward movement of the lens mounting seat 1, the elastic part 2 will bend and deform. To this end, the first reinforcing layer 41 is configured to be arranged opposite to the hollow area 5 so that the first reinforcing layer 41 can avoid the elastic part 2 to avoid collision between the first reinforcing layer 41 and the elastic part 2 .

[0135] Fig.21 : is a schematic diagram of stress simulation of the lens mounting seat 1 of this embodiment. The simulation result is the stress distribution of the stopper 12 when the first side surface 431 is configured as a plane when it is subjected to an impact force of 25KG and 0.08 milliseconds. The simulation results A, B, C and D in the figure are the simulation results when the first side surface 431 is inclined at 25°, 20°, 15° and 10° respectively. It can be seen from the figure that the maximum pressures of the simulation results A, B, C and D are 87.68Mpa, 82.97Mpa, 79.50Mpa and 89.58Mpa respectively.

[0136] Thus, the first side surface 431 can be configured as a plane, and the inclination angle is set to 15°. In this form, the third reinforcement layer 43 can improve the impact resistance and avoid the impact stress from being concentrated on the bottom of the fixing boss 121.
