Description

Technical Field

[0001] The present application relates to a camera module, and specifically to a periscope camera module. Background Art

[0002] In recent years, as electronic devices continue to rapidly develop and iterate towards miniaturization and high performance, under this trend, camera modules, as one of the standard configurations of electronic devices, users have become more and more stringent in terms of the size and imaging capabilities of camera modules. In order to further enhance the user experience, the industry is actively pursuing compact design and functional integration in the development of camera modules. Through technological innovation and functional integration, the industry is constantly promoting the development of camera modules towards a more compact and intelligent direction, and further realizing functions such as autofocus, zoom, anti-shake, and telephoto.

[0003] The periscope camera module is a special camera module that changes the light path through an optical path steering element so that it can be placed horizontally in electronic devices such as mobile phones, solving the problem of the telephoto camera module being too high due to the long optical length of the telephoto lens. This design allows the camera to provide a longer focal length and higher zoom capability without increasing the thickness of the module.

[0004] Taking the periscope camera module as an example, the lens is usually bonded to a fixed base or a movable carrier with adhesive. However, shrinkage occurs during the curing process of the adhesive, which may cause deformation of the adhesive on the outer wall of the lens, thereby affecting the shape of the internal lens mounting hole. This deformation will compress the edge of the lens installed in the lens mounting hole, causing deformation, and ultimately affecting the imaging quality of the optical system. When there is more adhesive attached to the outer wall of the lens, the shrinkage caused by the curing process will have a more significant impact on the deformation of the lens mounting hole, thereby reducing the imaging performance of the optical system.

[0035] Please refer to the attached Figure 1-Figure 9 A specific embodiment of a periscope camera module is further described.

[0036] In order to increase the connection strength between the optical lens 10 and the lens holder 20 and prevent the optical lens 10 from falling off due to impacts such as collisions, an adhesive such as glue is provided between the optical lens 10 and the lens holder 20. However, the adhesive may have a risk of variation due to shrinkage during curing, so that the adhesive attached to the outer peripheral wall of the lens barrel 11 may easily cause deformation of the lens mounting hole inside the lens barrel 11 during curing, thereby causing the peripheral edge of the lens installed in the lens mounting hole to deform due to extrusion, ultimately affecting the optical imaging performance of the optical system. In addition, the more adhesive is attached to the outer peripheral wall of the lens barrel 11, the more obvious the deformation of the lens mounting hole in the lens barrel 11 caused by the variation of adhesive curing, that is, the more obvious the impact on the optical performance of the optical system. Furthermore, due to the different coefficients of thermal expansion (CTE) of the adhesive and the lens barrel 11, the expansion and contraction deformations of the adhesive and the lens barrel 11 will be different under high and low temperature impacts, thereby generating stress between the lens barrel 11 and the adhesive. The stress acts on the lens barrel 11 to deform the lens barrel 11, and also causes deformation of the lens mounting hole inside the optical lens 10, thereby causing the peripheral edge of the lens installed in the lens mounting hole to deform due to extrusion, ultimately affecting the optical imaging performance of the optical system.

[0037] According to one aspect of the present application, a periscope camera module is provided, including at least one optical lens 10, at least one lens holder 20 and a plastic material 30, wherein the at least one optical lens 10 includes a lens barrel 11 and at least one lens accommodated in the lens barrel 11, the optical lens 10 defines an optical axis, the lens barrel 11 includes a lens barrel body 111 and a support portion 12, the support portion 12 protrudes from the lens barrel body 111 along a first direction, the support portion 12 includes a first surface 101 and a second surface 102 opposite to each other along the second direction, and a first surface 101 and a second surface 102 connected along the second direction. The opening 121 of the surface 101 and the second surface 102, the second direction is perpendicular to the first direction, at least one optical lens 10 is arranged in at least one lens holder 20, at least one lens holder 20 includes a receiving groove 200 facing the support portion 12, a gap 201 is provided between the support portion 12 and the receiving groove 200, at least a portion of the support portion 12 is spaced between the gap 201 and the opening 121; the adhesive material 30 is at least partially filled in the gap 201 and the opening 121 to fix the at least one optical lens 10 to the at least one lens holder 20. On the one hand, by providing the opening 121 in the support portion 12 of the lens barrel 11, the thickness of the support portion 12 can be reduced, and the deformation of the lens barrel body 111 of the lens barrel 11 due to the more obvious shrinkage of the thick support portion 12 during the curing and molding process of the lens barrel 11 is avoided, thereby reducing the risk of deformation of at least one lens accommodated in the lens barrel 11. Among them, the thickness of the support part 12 includes its dimensions along the first direction and the second direction; on the other hand, the gap 201 and the opening 121 are spaced by the support part 12 to avoid the glue 30 at least partially filled in the gap 201 and the opening 121 from being connected in a horizontal direction perpendicular to the second direction, thereby reducing the contact area between the glue 30 and the support part 12, thereby reducing the impact of the glue 30 on the support part 12 during curing and shrinkage, effectively avoiding deformation of the lens barrel 11, and improving the imaging stability of the periscope camera module.

[0038] Among them, Figure 1 As shown, the optical axis is perpendicular to the first direction and the second direction, wherein the first direction is defined as the width direction of the periscope camera module arranged along the X axis, the second direction is defined as the height direction of the periscope camera module arranged along the Z axis, and the optical axis direction is defined as the length direction of the periscope camera module arranged along the Y axis. It can be understood that the setting of the coordinate system can be flexibly set according to actual needs and is not limited here.

[0039] In some embodiments, Figure 2As shown, the support portion 12 extends from the outer peripheral wall of the lens barrel 11 along the first direction to the accommodating groove 200, and the opening 121 is opened in the middle area of ​​the support portion 12 along the second direction. The opening 121 is provided with an accommodating cavity 124, a first opening 122, and a second opening 123. The first opening 122 and the second opening 123 are connected to the accommodating cavity 124 and the outside respectively along the second direction, so that the opening 121 penetrates the support portion 12 along the second direction. Therefore, by providing the opening 121 structure penetrating the support portion 12 along the second direction on the lens barrel 11, at least a part of the adhesive 30 is arranged in the opening 121 and the gap 201 arranged at intervals, so as to disperse the stress generated by the adhesive 30 on the structure of the lens barrel 11 when curing, and reduce the deformation problem of the support portion 12 caused by the curing shrinkage of the adhesive 30. By providing the opening 121 that can only penetrate up and down in the middle area of ​​the support portion 12, and by separating the gap 201 and the opening 121 by at least a part of the support portion 12, the support portion 12 is made The hollow structure of the support portion 12 reduces the thickness of the support portion 12, effectively avoiding the shrinkage and deformation of the support portion 12 during curing. At the same time, the opening 121 is prevented from being connected with the gap 201, which causes the width of the adhesive material 30 in the horizontal direction perpendicular to the second direction to be too large, thereby reducing the contact area between the adhesive material 30 and the support portion 12, thereby reducing the impact of the adhesive material 30 on the support portion 12 during curing and shrinkage, and can also reduce the deformation of the lens mounting hole in the lens barrel 11 during the curing process of the adhesive material 30, which is beneficial to improving the optical imaging performance of the optical system.

[0040] It is understandable that the lens barrel 11 is flexibly installed and supported in the lens holder 20 by the support portion 12, and the position and angle of the lens barrel 11 can be finely adjusted under normal circumstances to meet different installation requirements or to more conveniently perform the optical alignment step. However, due to the different thermal expansion coefficients of the adhesive material 30 and the lens barrel 11, the expansion and contraction deformations of the adhesive material 30 and the lens barrel 11 are different under the impact of high or low temperature environments, and the stress generated between the adhesive material 30 and the lens barrel 11 causes deformation of the lens barrel 11 and the lens mounting hole inside the lens barrel 11, and further causes deformation of the peripheral edge of the lens installed in the lens mounting hole due to extrusion. Since the lens barrel 11 is made of resin material, volume shrinkage will occur during the curing process. Therefore, when the thickness of the support portion 12 along the first direction and along the second direction is large, this shrinkage will become more obvious in the local area, which may cause the support portion 12 to shrink and deform, thereby causing the lens mounting holes in the lens barrel 11 and the lens barrel body 111 to deform, thereby causing the peripheral edge of the lens installed in the lens mounting hole to deform due to extrusion, and finally affecting the optical imaging performance of the optical system. Therefore, in the present invention, the support portion 12 with a hollow opening 121 structure reduces the impact of the adhesive 30 on the lens barrel 11 when it is cured, reduces the deformation of the lens barrel 11 when it is stressed, reduces the phenomenon of imaging defects caused by the deformation of the lens barrel 11, and can also reduce the situation of the optical lens 10 falling off under stress, thereby improving the stability of the optical lens 10, thereby improving the imaging quality of the periscope camera module.

[0041] In other words, reference Figure 3As shown, two support parts 12 extend outward symmetrically from the lens barrel body 111 in opposite directions along the first direction, and each support part 12 is provided with an opening 121 penetrating along the second direction, wherein the opening 121 penetrates the support part 12 along the second direction, which can reduce the bubbles generated by the adhesive material 30 in the opening 121, thereby avoiding the problem of reduced bonding strength between the support part 12 and the lens holder 20 due to the generation of bubbles. Further, the opening 121 and the gap 201 are laterally separated by the outer side wall of the support part 12, and the adhesive material 30 is at least partially filled between the opening 121 and the gap 201. Therefore, by using the support portion 12 with the opening 121, the thickness of the support portion 12 can be reduced, thereby preventing the deformation of the lens barrel body 111 of the lens barrel 11 due to more obvious shrinkage caused by the thick support portion 12 during the curing and molding process of the lens barrel 11, thereby reducing the risk of deformation of at least one lens accommodated in the lens barrel 11; the glue material 30 can also be separated by the outer wall of the support portion 12, thereby reducing the width of the glue material 30 in the horizontal direction perpendicular to the second direction, thereby reducing the influence of the curing shrinkage of the glue material 30 on the lens barrel 11, thereby avoiding the reduction in imaging quality of the periscope camera module caused by the deformation of the lens barrel 11, and effectively preventing the support portion 12 from being too thick along the first direction, which will increase the stress on the inner diameter due to its own shrinkage when the lens barrel 11 is molded.

[0042] refer to Figure 4 and Figure 5 As shown, in some embodiments, the support portion 12 includes a first side wall 125, a second side wall 126, and a third side wall 127. The first side wall 125 and the second side wall 126 are located on both sides of the third side wall 127 along the optical axis direction, and integrally connect the third side wall 127 and the outer peripheral wall of the lens barrel body 111, defining the opening 121 in the space surrounded by the first side wall 125, the second side wall 126, and the third side wall 127. The opening 121 and the gap 201 are separated from each other by the outer side wall of the support portion 12, so that the glue 30 is separated by the outer side wall of the support portion 12, the thickness of the glue 30 is reduced, and the stress concentration effect of the glue 30 curing shrinkage on the shape of the lens barrel 11 is reduced.

[0043] In other words, if the opening 121 and the gap 201 are connected, at least a portion of the third side wall 127 is eliminated to form a slotted structure. At this time, the adhesive material 30 in the opening 121 is connected to the adhesive material 30 in the gap 201, resulting in a larger lateral width of the adhesive material 30 along the first direction, so that the contact area between the adhesive material 30 and the support portion 12 is increased, and when the adhesive material 30 solidifies and shrinks, the support portion 12 is subjected to a greater stress, causing the support portion 12 to be more easily deformed under the action of stress. During the curing process of the adhesive material 30, the curing and shrinkage of the adhesive material 30 will cause the support portion 12 to deform. For example, the support portion 12 will deform in the direction of the opening 121, thereby causing the lens barrel body 111 to deform, resulting in the deformation of the lens mounting hole in the lens barrel 11, and then causing the peripheral edge of the lens mounted in the lens mounting hole to deform due to extrusion, ultimately affecting the optical imaging performance of the optical system. In the present invention, the opening 121 and the gap 201 are not connected, and the opening 121 is a ring-shaped hollow structure. The adhesive material 30 flows in through the opening 121 structure. Thanks to the structure in which the adhesive material 30 between the opening 121 and the gap 201 is intermittently arranged, the bonding area between the adhesive material 30 and the lens barrel body 111 is reduced, and the stress generated on the lens barrel 11 when the adhesive material 30 is cured is further dispersed, reducing the deformation effect on the lens barrel 11, thereby increasing the structural stability of the support portion 12 and the lens barrel 11.

[0044] In some embodiments, reference Figure 6 As shown, the adhesive material 30 includes a first adhesive material 31 and a second adhesive material 32. The first adhesive material 31 in the accommodating cavity 124 and the second adhesive material 32 in the gap 201 are separated by at least a portion of the support portion 12. The materials of the first adhesive material 31 and the second adhesive material 32 are the same or different. By separating the first adhesive material 31 and the second adhesive material 32, the first adhesive material 31 is distributed in the opening 121 and solidified to form a columnar structure. The solidified first adhesive material 31 passes through and is inserted into the opening 121 to further enhance the support connectivity of the adhesive material 30 to the optical lens 10, thereby enhancing the stability of the optical lens 10.

[0045] In some embodiments, the adhesive material 30 is formed by curing only a single adhesive, and the adhesive material 30 includes a first adhesive material 31 and a second adhesive material 32. The first adhesive material 31 located in the opening 121 and the second adhesive material 32 located in the gap 201 are separated by at least a portion of the support portion 12. The bonding and molding process of the adhesive material 30 is to first apply the adhesive inside the gap 201, then place the lens barrel 11 in the lens holder 20 along the second direction, and match the support portion 12 provided on the lens barrel 11 with the receiving groove 200. During the installation process, due to squeezing the adhesive in the gap 201, at least a portion of the adhesive overflows into the opening 121. After the adhesive is cured, the support portion 12 separates the first adhesive material 31 in the receiving cavity 124 and the second adhesive material 32 in the gap 201, thereby reducing the bonding area between the adhesive material 30 and the outer wall of the lens barrel body 111, thereby reducing the stress generated on the support portion 12 when the adhesive is cured. Furthermore, thanks to the fact that the first adhesive material 31 is distributed in the opening 121 and forms a columnar structure after solidification, the solidified first adhesive material 31 penetrates and is inserted into the opening 121 to further enhance the supporting connectivity of the adhesive material 30 to the optical lens 10, and increases the connection strength between the lens barrel 11 and the lens holder 20, thereby increasing the reliability and stability of the periscope camera module.

[0046] In some embodiments, the adhesive material 30 can only be one or more of UV curing adhesive, epoxy structural adhesive, curing adhesive and hot melt adhesive to bond the lens barrel 11 and the lens holder 20 and provide good bonding performance, further improving the reliability of the optical lens 10, thereby enhancing the imaging quality of the periscope camera module.

[0047] In some embodiments, the adhesive material 30 is formed by curing only a single adhesive, and the adhesive material 30 includes a first adhesive material 31 and a second adhesive material 32, and the first adhesive material 31 located in the opening 121 and the second adhesive material 32 located in the gap 201 are separated by at least a portion of the support portion 12. The bonding and molding process of the adhesive material 30 is to first place the lens barrel 11 in the lens holder 20 along the second direction, then relatively match the support portion 12 provided on the lens barrel 11 with the receiving groove 200, and then apply the adhesive in the gap 201 and the opening 121 structure. Thanks to the inclined smooth inner wall structure of the gap 201 and the opening 121, the adhesive conveniently flows into the opening 121 structure and forms a discontinuous adhesive material 30 structure after curing, thereby increasing the bonding area between the adhesive and the inner wall of the opening 121, reducing the stress on the support portion 12 when the adhesive is cured, and thus reducing the deformation phenomenon caused by the lens barrel 11 when subjected to external force.

[0048] In some embodiments, the adhesive material 30 is formed by curing two adhesives, and the adhesive material 30 includes a first adhesive material 31 and a second adhesive material 32 having different materials, and the first adhesive material 31 located in the opening 121 and the second adhesive material 32 located in the gap 201 are separated by at least a portion of the support portion 12. And the adhesive force provided by the first adhesive material 31 is greater than the adhesive force provided by the cured second adhesive material 32. The bonding and molding process of the adhesive material 30 is to first arrange the lens barrel 11 in the lens holder 20 along the second direction, then relatively match the support portion 12 provided on the lens barrel 11 with the receiving groove 200, and arrange the second adhesive material 32 in the gap 201, and cure the second adhesive material 32 to achieve pre-fixation between the support portion 12 and the receiving groove 200. Before or after the pre-fixation, the relative position of the support portion 12 and the receiving groove 200 can be adjusted to achieve fine adjustment of the position and angle of the lens barrel 11. Then, the first adhesive material 31 is arranged in the opening 121 structure and cured to completely cure and bond the support portion 12 to the receiving groove 200 of the lens holder 20, so as to increase the strength between the support portion 12 and the lens holder 20. In other words, during the assembly process of the lens barrel 11 and the lens holder 20, the shrinkage of the first adhesive material 31 and the second adhesive material 32 during curing can be avoided, thereby avoiding stress on the support portion 12, thereby changing the position and shape of the lens barrel 11. It is also possible to fine-tune the position and angle of the lens barrel 11, so as to adapt to different installation requirements and more conveniently perform the optical alignment step, further enhancing the imaging quality of the periscope camera module.

[0049] In some embodiments, the adhesive used to cure to form the first adhesive material 31 is selected from one or more of UV curing adhesive or UV thermosetting adhesive. Thanks to the rapid curing performance of the UV curing adhesive and / or UV thermosetting adhesive, the production efficiency is improved, and the first adhesive material 31 formed after curing has a high bonding strength, so that the lens barrel 11 and the lens holder 20 are firmly bonded, the stress generated by shrinkage during curing is small, and the external force generated on the lens barrel 11 is small, which further improves the stability of the optical lens 10.

[0050] In some embodiments, the adhesive that cures to form the second adhesive material 32 is selected from one or more of thermosetting adhesive or UV thermosetting adhesive. Since thermosetting adhesive or UV thermosetting adhesive can be used in combination with a variety of materials, flexibility is provided for the diversified design of the periscope camera module. Thanks to the excellent high temperature resistance and moisture resistance of low-temperature thermosetting adhesive, the reliability of the periscope camera module in high temperature or humid environments is enhanced. The rapid curing rate of UV thermosetting adhesive can improve production efficiency. Furthermore, since both UV thermosetting adhesive and low-temperature thermosetting adhesive have high bonding strength, the stability of the optical lens 10 is improved after curing.

[0051] In some embodiments, the first adhesive material 31 and the second adhesive material 32 are formed by curing using different liquid adhesives. The bonding and molding process of the adhesive material 30 is to first apply the adhesive to form the second adhesive material 32 in the gap 201, then place the lens barrel 11 in the lens holder 20 along the second direction, and then relatively match the support portion 12 provided on the lens barrel 11 with the receiving groove 200 provided on the lens holder 20. When squeezing the adhesive provided between the support portion 12 and the gap 201, at least a portion of the adhesive overflows into the opening 121 structure. In other words, this may result in at least a portion of the top of the support portion 12 and the receiving groove 200 close to the first surface 101 of the support portion 12 not being covered by the second adhesive material 32. In order to further enhance the bonding strength, the first adhesive material 31 may be disposed in the empty space to further enhance the bonding strength between the support portion 12 and the lens holder 20, thereby improving the stability of the optical lens 10.

[0052] In some embodiments, reference Figure 4 and Figure 6 As shown, the second adhesive material 32 is provided with a side adhesive portion 321 and a bottom adhesive portion 322, the side adhesive portion 321 surrounds the outer peripheral wall of the support portion 12, the bottom adhesive portion 322 and the side adhesive portion 321 are filled in the gap 201 between the support portion 12 and the receiving groove 200, and the first adhesive material 31 is filled from the bottom adhesive portion 322 into the opening 121, the first adhesive material 31 and the bottom adhesive portion 322 are connected, and the first adhesive material 31 and the side adhesive portion 321 are arranged opposite to each other at intervals. Further, the bottom of the first adhesive material 31 is connected to the second adhesive material 32 to increase the bonding stability of the adhesive material 30, thereby improving the reliability of the optical lens 10. Since the adhesive is filled in the opening 121 and the gap 201, the opening 121 and the gap 201 are separated by the outer side wall of the support portion 12, that is, the opening 121 on the support portion 12 and the gap 201 are not connected to each other. Therefore, without increasing the width of the adhesive 30 , the stress on the support portion 12 during the curing of the adhesive is further reduced, thereby improving the imaging quality of the periscope camera module.

[0053] refer to Figure 6As shown, in some embodiments of the present application, the first adhesive material 31 is provided with an end portion 311 and a middle portion 312, the size of the end portion 311 of the first adhesive material 31 is larger than the size of the middle portion 312, the shape of the first adhesive material 31 corresponds to the opening 121 in the support portion 12, and the size of the first adhesive material 31 is adapted to the size of the opening 121 provided on the support portion 12. It should be understood that in the manufacturing process of the support portion 12, since the opening 121 of the support portion 12 has a certain height along the second direction, it is difficult to use only one injection molding. Therefore, in the present application, a two-end split mold method is used, that is, an upper mold and a lower mold with a symmetrical structure are used, and an injection molding material is injected between the upper mold and the lower mold to form the support portion 12 with the opening 121. In this way, the contact portion between the upper mold and the lower mold is the dividing line, and the support portion 12 and the opening 121 in the support portion 12 have a symmetrical structure relative to the dividing line. It should be understood that the two-end mold separation is conducive to the molding of the support part 12 and the opening 121 in the support part 12, thereby ensuring the quality of the molded support part 12. Furthermore, the inner side wall of the opening 121 of the support part 12 is inclined from the outer end to the middle to facilitate the demolding process.

[0054] refer to Figure 4 and Figure 5 As shown, in some embodiments, the inner diameter of the first opening 122 of the opening 121 is larger than the inner diameter of the accommodating cavity 124, the inner diameter of the second opening 123 of the opening 121 is larger than the inner diameter of the accommodating cavity 124, the inner peripheral wall of the support portion 12 gradually extends from the first opening 122 and the second opening 123 to the accommodating cavity 124, the side of the first adhesive 31 is inclined along the inner peripheral wall forming the accommodating cavity 124, and the width of the end 311 of the first adhesive 31 is larger than the width of the middle part 312. Further, especially when the plastic part is cooled and contracted, the vertical inner side wall of the opening 121 is prone to burrs or cracks during demoulding, while the inclined inner side wall helps to reduce defects during part production and is also conducive to reducing the friction generated when the adhesive penetrates into the inner side wall of the opening 121. Since the size of the end 311 of the opening 121 is larger than the size of the middle part 312, the adhesive can more conveniently enter the opening 121 through the inner side wall of the opening 121 at an inclined angle. It is worth mentioning that during the molding process of the support portion 12, thanks to the inner side wall of the inclined opening 121, the friction between the mold and the molded component is reduced, the convenience of the demolding process is improved, the mold is smoothly separated from the molded component, and the quality of the lens barrel 11 formed after the demolding process is further improved.

[0055] In other words, during the molding process of the support portion 12, the mold needs to be separated smoothly from the molded part. The inclined inner wall can reduce the friction between the mold and the part, making demolding easier and smoother. Furthermore, the support portion 12 with a vertical inner wall is prone to burrs or cracks during demolding, especially when the plastic part cools and shrinks. The inclined inner wall helps to reduce the quality problems of the part surface. Therefore, the size of the end 311 of the first adhesive 31 is larger than the size of the middle part 312, and the inner wall of the opening 121 gradually tilts inward from the outer end to the middle, which is convenient for the subsequent demolding process.

[0056] refer to Figure 4 and Figure 5 As shown, in some embodiments, the inner diameter of the first opening 122 of the opening 121 is larger than the inner diameter of the accommodating cavity 124, the inner diameter of the second opening 123 of the opening 121 is larger than the inner diameter of the accommodating cavity 124, the inner peripheral wall of the support portion 12 gradually extends from the first opening 122 and the second opening 123 to the accommodating cavity 124, the side of the first adhesive 31 is inclined along the inner peripheral wall forming the accommodating cavity 124, and the width of the end 311 of the first adhesive 31 is larger than the width of the middle part 312. Further, especially when the plastic part is cooled and contracted, the vertical inner side wall of the opening 121 is prone to burrs or cracks during demoulding, and the inclined inner side wall helps to reduce defects during part production. Since the size of the end 311 of the opening 121 is larger than the size of the middle part 312, the adhesive can more conveniently enter the opening 121 through the inner side wall of the opening 121 at an inclined angle. It is worth mentioning that during the molding process of the support portion 12, thanks to the inner side wall of the inclined opening 121, the friction between the mold and the molded component is reduced, the convenience of the demolding process is improved, the mold is smoothly separated from the molded component, and the quality of the lens barrel 11 formed after the demolding process is further improved.

[0057] In some embodiments, the lens barrel 11 and the support portion 12 are integrally formed by using a two-end split mold method during the mold opening stage, so that the support portion 12 has a symmetrical structure. Furthermore, the two-end split mold method is conducive to the demolding operation of the lens barrel 11 during molding, thereby ensuring the quality of the lens barrel 11 components after molding.

[0058] In some embodiments, the number of supporting parts 12 provided on the lens barrel 11 is at least two, and the supporting parts 12 are symmetrically arranged on both sides of the lens barrel body 111 relative to the optical axis, so as to enhance the support stability of the optical lens 10. The symmetrically arranged supporting parts 12 are each provided with an opening 121, further increasing the symmetry of the lens barrel 11 structure.

[0059] In some embodiments, the length of the lens barrel 11 along the optical axis direction ranges from 3.0mm to 5.0mm, specifically, 3.0mm, 3.4mm, 3.6mm, 3.8mm, 4.0mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, and 5.0mm. The single side wall of the lens barrel 11 within this length range is only provided with a support portion 12, and only one opening 121 is provided in the support portion 12. Therefore, not only enough space is reserved for the support portion 12 provided on the side wall of the lens barrel 11, but also the strength and manufacturability of the support portion 12 are guaranteed. Further, it is also possible to ensure that the opening 121 has a certain size, not only to allow the adhesive to enter the opening 121 to increase the bonding strength, but also to provide the support portion 12 with a suitable stress relaxation ability while improving the connection stability, so as to reduce the phenomenon of the lens barrel 11 falling off caused by external impact. It is also possible to reduce the width of the adhesive material 30 formed after the adhesive is cured, and further reduce the stress effect of the adhesive curing on the lens barrel 11.

[0060] In some embodiments, the ratio of the length of the support portion 12 to the lens barrel 11 along the optical axis is 0.30-0.50, specifically 0.30, 0.33, 0.36, 0.39, 0.42, 0.45, 0.48, 0.49, 0.50. It is worth mentioning that the support portion 12 has a certain length to provide sufficient support area for the lens barrel 11, further improving the stability and manufacturability of the lens barrel 11.

[0061] In some embodiments, the length ratio of the opening 121 to the support portion 12 along the optical axis is in the range of 0.50-0.80, specifically 0.50, 0.53, 0.56, 0.59, 0.62, 0.65, 0.68, 0.71, 0.74, 0.77, 0.80. The opening 121 of a certain size ensures that the support portion 12 has good structural strength and manufacturability.

[0062] In some embodiments, the ratio of the width of the opening 121 to the support portion 12 along the first direction is in the range of 0.40-0.60, specifically 0.40, 0.42, 0.44, 0.46, 0.48, 0.50, 0.52, 0.54, 0.56, 0.58, 0.60. It is worth mentioning that the opening 121 having a certain size is not only conducive to the smooth entry of the adhesive into the inside of the opening 121, but also further enhances the bonding strength between the lens barrel 11 and the lens holder 20, thereby increasing the stability of the optical lens 10.

[0063] In some embodiments, the support portion 12 satisfies at least one of the following conditions:

[0064] The length ratio of the support portion 12 and the lens barrel 11 along the optical axis direction is in the range of 0.35-0.45;

[0065] The length ratio of the opening 121 and the support portion 12 along the optical axis is in the range of 0.60-0.70;

[0066] The ratio of the width of the opening 121 to the width of the support portion 12 along the first direction is in the range of 0.45-0.55.

[0067] Furthermore, the size of the opening 121 should not be too large, which helps to reduce the bonding area between the support portion 12 and the adhesive material 30 and reduce the stress on the lens barrel 11 when the adhesive is cured.

[0068] In some embodiments, the length of the support portion 12 along the optical axis is 1.85 mm; the length of the lens barrel 11 along the optical axis is 4.2 mm; and the ratio of the length of the support portion 12 along the optical axis to the length of the lens barrel 11 along the optical axis is 0.44.

[0069] In some embodiments, the length of the opening 121 along the optical axis is 1.02 mm, the length of the support portion 12 along the optical axis is 1.69 mm, and the ratio of the length of the opening 121 along the optical axis to the length of the support portion 12 along the optical axis is 0.60.

[0070] In some embodiments, the length of the opening 121 along the first direction is 0.6 mm, the length of the support portion 12 along the first direction is 1.16 mm, and the ratio of the width of the opening 121 along the first direction to the width of the support portion 12 along the first direction is 0.52.

[0071] In some embodiments, the two support portions 12 extend outwardly symmetrically from both sides of the lens barrel 11 along the first direction, the opening 121 penetrates the first surface 101 and the second surface 102 of the support portion 12, the first side wall 125, the second side wall 126 and the third side wall 127 are an annular integrated structure, the first side wall 125 and the second side wall 126 separate the opening 121 and the gap 201 along the optical axis direction, and the third side wall 127 separates the opening 121 and the gap 201 along the first direction. It is worth mentioning that in some embodiments, the length of the support portion 12 along the optical axis direction is less than the length of the lens barrel 11 along the optical axis direction.

[0072] Furthermore, when the adhesive material 30 in the opening 121 is connected to the adhesive material 30 in the gap 201, the lateral width of the adhesive material 30 along the first direction is increased, resulting in an increase in the contact area between the adhesive material 30 and the support portion 12, so that the support portion 12 is subjected to greater stress. Further, when the adhesive material 30 solidifies and shrinks, the support portion 12 is deformed. For example, the support portion 12 will deform in the direction of the opening 121, thereby causing the lens barrel body 111 to deform, further causing the lens mounting hole inside the lens barrel 11 to deform, and further causing the peripheral edge of the lens installed in the lens mounting hole to deform due to extrusion, ultimately affecting the optical imaging performance of the periscope camera module. It is worth mentioning that in some embodiments of the present application, the adhesive material 30 can be only provided on the support portion 12, so as to facilitate fixing the lens barrel 11 in the lens holder 20, and further reduce the stress generated on the lens barrel 11 when the adhesive material 30 solidifies.

[0073] As the requirements for imaging quality of periscope camera modules increase, the optical performance of the optical lens 10 can be enhanced by increasing the number of lens pieces inside the lens barrel 11. Figure 8 As shown, in some embodiments, the periscope camera module further includes a first support portion 128 and a second support portion 129 arranged at intervals along the optical axis direction on the outer side wall of the lens barrel body 111, the first support portion 128 and the second support portion 129 protrude from the lens barrel body 111 along the first direction at intervals, the first support portion 128 is provided with a first opening 1211, the second support portion 129 is provided with a second opening 1212, the first opening 1211 penetrates the first surface 101 and the second surface 102 of the first support portion 128 along the second direction, and the second opening 1212 penetrates the first surface 101 and the second surface 102 of the second support portion 129 along the second direction. By arranging the first support portion 128 and the second support portion 129 at intervals, the adhesive material 30 in the first opening 1211 and the second opening 1212 provided on the first support portion 128 and the second support portion 129 are not connected to each other, thereby reducing the stress effect on the lens barrel 11 caused by the adhesive material 30 when it is cured and shrunk. Since the adhesive material 30 has a certain length along the optical axis direction, the amount of adhesive material 30 used for bonding the lens barrel 11 and the lens holder 20 is increased, the bonding strength is further improved, and the reliability of the optical lens 10 is improved.

[0074] As the performance requirements for the optical lens 10 are gradually increasing, in order to further improve the imaging quality, the number of lens pieces is usually increased to improve the resolution of the optical lens 10. However, increasing the number of lens pieces will also increase the length of the lens barrel 11 along the optical axis. In other words, in order to increase the connection stability between the lens barrel 11 and the lens holder 20, the length of the support portion 12 along the optical axis needs to be increased at the same time. Fig. 9As shown, in some embodiments, the support portion 12 with an increased length along the optical axis direction includes a first opening 1211 and a second opening 1212, the first opening 1211 and the second opening 1212 are arranged at intervals along the optical axis direction on the support portion 12, and the first opening 1211 and the second opening 1212 are spaced through the first surface 101 and the second surface 102 of the support portion 12 along the second direction. Thanks to the unconnected structure of the first opening 1211 and the second opening 1212, the adhesive material 30 inside the opening 121 and the adhesive material 30 arranged inside the gap 201 are separated from each other to avoid being connected to each other. Not only can the length of the adhesive material 30 along the optical axis direction and the first direction be avoided from being further increased, thereby reducing the stress effect on the support portion 12 when the adhesive material 30 is cured, but also the bonding strength between the lens barrel 11 and the lens holder 20 is further improved after the amount of the adhesive material 30 used is increased, thereby enhancing the reliability of the optical lens 10.

[0075] In other words, in order to reduce the impact of the curing of the adhesive material 30 on the structure of the lens barrel 11, Figure 4 and Figure 7 As shown, in some embodiments, an overflow glue groove 23 is provided in the concave portion of the accommodating groove 200. Therefore, when there is too much glue 30 in the accommodating groove 200 and it overflows, the glue 30 overflows from the bottom of the supporting portion 12 away from the light incident end and preferentially flows into the overflow glue groove 23, thereby avoiding adhesion to the outer peripheral wall of the lens barrel 11, further reducing the external force generated by the curing of the glue 30 on the lens barrel body 111 and the supporting portion 12, reducing the deformation of the lens barrel 11, and thereby improving the imaging quality of the periscope camera module.

[0076] In some embodiments, the periscope camera module is provided with a single lens barrel 11 structure and / or a dual lens barrel 11 structure. The single lens barrel 11 structure is conducive to reducing the volume occupied by the periscope camera module, thereby increasing the portability of the periscope camera module and reducing the manufacturing cost. The dual lens barrel 11 structure is conducive to improving the image clarity and quality and increasing the optical zoom range of the periscope camera module.

[0077] In some embodiments, reference Figure 4 , Figure 7 As shown, a receiving groove 200 is provided on the lens holder 20, and the receiving groove 200 faces the supporting portion 12 arranged oppositely on the lens barrel 11 and is adapted to accommodate the supporting portion 12. Since a gap 201 is provided between the receiving groove 200 and the supporting portion 12, it is convenient to set the adhesive material 30, and it is convenient to control the amount of the adhesive material 30, further enhancing the bonding strength between the lens barrel 11 and the lens holder 20, facilitating the subsequent assembly process, thereby enhancing the reliability of the optical lens 10.

[0078] Continue to refer Figure 8As shown, in some embodiments, the support portion 12 includes a first support portion 128 and a second support portion 129, and the first support portion 128 and the second support portion 129 are symmetrical along the optical axis direction and are spaced apart on the same side of the outer peripheral wall of the lens barrel 11. A first opening 1211 is provided in the middle area of ​​the first support portion 128, and a second opening 1212 is provided in the middle area of ​​the second support portion 129. The first opening 1211 and the second opening 1212 are both provided with a receiving cavity 124, a first opening 122 and a second opening 123, and the first opening 1211 and the second opening 1212 are spaced apart along the second direction and penetrate the first surface 101 and the second surface 102 of the first support portion 128 and the second support portion 129, and the inner area surrounded by the first opening 122 and the second opening 123 of the first opening 1211 and the second opening 1212 respectively forms a receiving cavity 124. The length of the first opening 1211 along the optical axis direction is less than the length of the first support portion 128 along the optical axis direction, and the length of the first opening 1211 along the first direction is less than the length of the first support portion 128 along the first direction. The length of the second opening 1212 along the optical axis direction is less than the length of the second support portion 129 along the optical axis direction, and the length of the second opening 1212 along the first direction is less than the length of the second support portion 129 along the first direction. The adhesive material 30 and the gap 201 in the first opening 1211 and the second opening 1212 are both separated by the outer wall of the support portion 12, that is, the first opening 1211 and the second opening 1212 on the support portion 12 are not connected to the gap 201. Therefore, while avoiding increasing the thickness of the adhesive material 30 along the first direction, the stress effect of the adhesive material 30 on the support portion 12 when solidifying is further reduced, thereby improving the imaging quality of the periscope camera module.

[0079] Furthermore, the lens holder 20 is provided with a single receiving groove 200, the support portion 12 includes a first supporting portion 128 and a second supporting portion 129, a gap 201 is provided between the receiving groove 200 and the support portion 12, and the shape of the receiving groove 200 is respectively adapted to the shapes of the first supporting portion 128 and the second supporting portion 129. The provided receiving groove 200 facilitates the coating process of the adhesive material 30, thereby improving production efficiency.

[0080] Furthermore, the lens holder 20 is provided with two receiving grooves 200, two support portions 12 are provided on the lens barrel 11, a gap 201 is provided between the receiving grooves 200 and the support portions 12, the shape of the receiving grooves 200 is adapted to the shape of the support portions 12, and a single receiving groove 200 accommodates a single support portion 12. The provided receiving grooves 200 facilitate the coating process of the adhesive material 30, thereby improving production efficiency.

[0081] refer to Fig. 9As shown, in some embodiments, the lens holder 20 is provided with a receiving groove 200, and a gap 201 is provided between the receiving groove 200 and the supporting portion 12, and the shape of the receiving groove 200 is adapted to the shape of the supporting portion 12. In order to maintain the stability of the optical lens 10, the supporting portion 12 is symmetrically arranged on the outer peripheral wall of the lens barrel 11 along the optical axis direction, and a first opening 1211 and a second opening 1212 are provided in the middle area of ​​the supporting portion 12. The first opening 1211 and the second opening 1212 are arranged in the supporting portion 12 at intervals along the optical axis direction, and the first opening 1211 and the second opening 1212 penetrate the first surface 101 and the second surface 102 of the supporting portion 12 at intervals along the second direction. Thanks to the structure of the first opening 1211 and the second opening 1212 arranged at intervals, the adhesive material 30 arranged inside the first opening 1211 and the second opening 1212 is not connected to each other, thereby reducing the stress generated when the adhesive material 30 is cured. It can be understood that the setting of the opening 121 structure not only reduces the external force load on the lens barrel 11 when the adhesive 30 is cured, thereby causing deformation, but also enhances the bonding strength between the lens holder 20 and the lens barrel 11 without increasing the thickness of the adhesive 30 along the first direction, thereby increasing the reliability of the optical lens 10.

[0082] Furthermore, by providing two openings 121 in a single support portion 12, it is avoided that when a single opening 121 structure that is longer in the optical axis direction is provided in a lens barrel 11 that is longer in the optical axis direction, the adhesive material 30 is cured and contracted to produce a greater stress on the lens barrel 11, thereby affecting the imaging quality of the periscope camera module. Therefore, in one embodiment of the present application, for a lens barrel 11 that is 5.0mm-8.0mm long in the optical axis direction, a support portion 12 extending in the first direction and the optical axis direction can be provided on a single-side outer peripheral wall of the lens barrel body 111, wherein the length of the support portion 12 extending in the optical axis direction is greater than the length of the support portion 12 extending in the first direction, and the first opening 1211 and the second opening 1212 are provided in the support portion 12 at intervals in the optical axis direction. In this way, the plurality of first adhesive materials 31 can provide a more stable support for the lens barrel 11, and by reducing the width of the adhesive materials 30 connected to each other, the stress on the lens barrel 11 generated by the adhesive material 30 when solidifying is dispersed to a greater extent, further reducing the stress on the lens barrel 11 generated by the adhesive material 30 when solidifying, avoiding the deformation effect of the structure of the lens barrel 11 caused by stress concentration, and further enhancing the imaging quality of the optical lens 10.

[0083] In some embodiments, the steering element 40 is mounted on the lens holder 20 to control the direction of the light. The present application does not limit the angle between the incident surface and the exit surface of the steering element 40. The steering element 40 with an angle of 30°, 45°, 60° or 90° between the incident surface and the exit surface can be selected according to the actual installation environment requirements. The present application does not limit the type of the steering element 40. Generally, in order to better control the optical path, the steering element 40 can be a prism, a reflector or a beam splitter.

[0084] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present application, the periscope camera module includes a lens holder 20 and an optical system, the lens holder 20 is a frame, and the optical system is assembled inside the lens holder 20. The optical system includes a steering element 40, an aperture stop (not shown in the figure), a lens barrel 11 and a photosensitive component (not shown in the figure) distributed in sequence along the Y-axis direction, specifically, the light emitting direction of the steering element 40, the axial direction of the lens barrel 11 and the normal direction of the photosensitive component (not shown in the figure) are all arranged along the Y-axis direction. Among them, the optical system is located on the side of the lens holder 20 close to the incident light, the aperture stop (not shown in the figure) and the lens barrel 11 are both located in the central area of ​​the lens holder 20, and the photosensitive component (not shown in the figure) is located on the side of the lens holder 20 away from the incident light.

[0085] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present application, the steering element 40 has an incident surface and an exit surface, the incident surface and the exit surface intersect, and the propagation direction of the light is changed by the steering element 40 to fold the optical path. The aperture stop (not shown in the figure) is used to adjust the aperture of the light, so that the amount of light incident on the lens barrel 11 can be adjusted. The lens barrel 11 is through along the optical axis and has a lens mounting hole, and at least one optical lens is distributed in the lens mounting hole along the optical axis, so as to realize the convergence of the light by the lens barrel 11. After receiving the converged light, the photosensitive component (not shown in the figure) converts the received light signal into an electrical signal for imaging processing.

[0086] In some embodiments, the lens holder 20 is fixedly installed in the periscope camera module or is driven by a motor to be movably installed in the periscope camera module along the optical axis direction, so as to realize optical focus and / or optical zoom function, further improve the imaging quality of the periscope camera module, and enhance market competitiveness.

[0087] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
