[0002] The increasing demands for higher resolution in existing lenses have led to even higher requirements for the coaxiality of internal optical groups.

[0003] However, given the limited existing processing capabilities, it is impossible to guarantee the coaxiality of the internal components of the lens, often preventing it from meeting optical design requirements. Utility Model Content

[0004] The main purpose of this invention is to propose a zoom lens alignment system and a zoom lens, which aims to solve the problem that, under the limited existing processing capabilities, it is impossible to guarantee the coaxiality of the internal groups of the lens, which often makes it unable to meet the optical design requirements.

[0005] To achieve the above objectives, the zoom lens alignment system proposed in this utility model includes:

[0006] The housing extends laterally; and,

[0007] The alignment structure includes an alignment part and an alignment group. The alignment group is located inside the housing and is movably disposed laterally on the alignment part. The alignment part is disposed on the housing and can drive the alignment group to move longitudinally and vertically. The alignment group is used to mount a movable lens.

[0008] In one embodiment, the housing has a first through hole extending through at least one end in the transverse direction;

[0009] The core-aligning part includes:

[0010] A drive guide rod, disposed within the housing and movably connected to the self-aligning assembly; and,

[0011] The first eccentric wheel is rotatably disposed in the first through hole along the horizontally extending axis. The first eccentric wheel is fixedly connected to the drive guide rod and is eccentrically disposed with the drive guide rod to drive the drive guide rod to move in the longitudinal and vertical directions.

[0012] In one embodiment, the end of the first eccentric wheel facing the drive guide rod is recessed with a groove, and a limiting part is provided in the groove;

[0013] The drive guide rod is provided with a mating part corresponding to the limiting part. The mating part can extend into the groove and cooperate with the limiting part.

[0014] In one embodiment, the end of the first eccentric wheel away from the drive guide rod is further provided with a rotating part, which is used to drive the first eccentric wheel to rotate along a laterally extending axis.

[0015] In one embodiment, the core-aligning structure further includes a guide rod extending laterally within the housing and movably connected to the core-aligning group, the guide rod being used to guide the movement of the core-aligning group in the lateral direction.

[0016] In one embodiment, the core-adjusting group is provided with an elongated hole in the transverse direction;

[0017] The guide rod passes through the elongated hole and can slide along the extension direction of the elongated hole.

[0018] In one embodiment, the housing has a second through hole extending through at least one end in the transverse direction;

[0019] The self-aligning structure also includes a second eccentric wheel, which is rotatably disposed in the second through hole. The second eccentric wheel is fixedly connected to the guide rod and is eccentrically disposed with respect to the guide rod, so as to drive the guide rod to move longitudinally and vertically.

[0020] In one embodiment, the housing includes an inner shell and an outer shell spaced apart. The outer shell is fitted over the outer side of the inner shell, and the inner sidewall of the outer shell is provided with a plurality of telescopic members spaced apart along the circumference. The plurality of telescopic members are used to abut against the inner shell together, and each telescopic member can extend or retract radially along the outer shell. The inner shell is provided with the adjusting part and the adjusting group.

[0021] In one embodiment, the lens adjustment structure further includes a locking structure disposed in the housing and connected to the adjusting part, the locking structure being used to lock the adjusting part after the adjusting part has adjusted the position of the adjusting group.

[0023] In this invention, the zoom lens alignment system includes a housing and an alignment structure. The housing extends laterally, and the alignment structure includes an alignment section and an alignment group. The alignment group is located within the housing and is laterally movable within the alignment section. The alignment section is mounted on the housing and can drive the alignment group to move longitudinally and vertically. The alignment group is used to mount a movable lens. During assembly, the operator manipulates the alignment section to move the alignment group longitudinally and vertically, thereby adjusting the position of the movable lens in the longitudinal and vertical directions. This adjusts the coaxiality of multiple groups within the lens, ensuring that the coaxiality of the multiple groups meets optical design requirements during assembly. Furthermore, because the alignment group is laterally movable within the alignment section, after alignment, the alignment group can move laterally to move the movable lens laterally, changing only the position of the movable lens. This achieves the zoom function of the lens while ensuring the coaxiality of multiple groups. Attached Figure Description

[0036] This invention proposes a zoom lens alignment system. It aims to solve the problem that, given limited current manufacturing capabilities, the coaxiality of the internal components of a lens cannot be guaranteed, often preventing it from meeting optical design requirements.

[0037] Please see Figure 1-5In one embodiment of the present invention, the zoom lens adjustment system 100 includes a housing 1 and an adjustment structure 2. The housing 1 extends laterally, and the adjustment structure 2 includes an adjustment part 21 and an adjustment group 22. The adjustment group 22 is located inside the housing 1 and is movably disposed laterally on the adjustment part 21. The adjustment part 21 is disposed on the housing 1 and can drive the adjustment group 22 to move longitudinally and vertically. The adjustment group 22 is used to mount a movable lens.

[0038] In the technical solution of this utility model, the zoom lens adjustment system 100 includes a housing 1 and an adjustment structure 2. The housing 1 extends laterally, and the adjustment structure 2 includes an adjustment part 21 and an adjustment group 22. The adjustment group 22 is located inside the housing 1 and is movably disposed laterally on the adjustment part 21. The adjustment part 21 is disposed on the housing 1 and can drive the adjustment group 22 to move longitudinally and vertically. The adjustment group 22 is used to mount a movable lens. During assembly, the operator manipulates the adjusting unit 21 to move the adjusting group 22 in the longitudinal and vertical directions, thereby adjusting the position of the movable lens in the longitudinal and vertical directions to adjust the coaxiality of multiple groups inside the lens. The coaxiality of the multiple groups meets the optical design requirements during assembly. At the same time, since the adjusting group 22 is movably located in the adjusting unit 21 in the lateral direction, after the adjustment is completed, the adjusting group 22 can move laterally to move the movable lens in the lateral direction. By only changing the position of the movable lens in the lateral direction, the zoom function of the lens is achieved while ensuring the coaxiality of multiple groups.

[0039] It is understood that the adjusting part 21 only drives the adjusting group 22 to move longitudinally and vertically during the lens assembly process, thereby driving the movable lens to move longitudinally and vertically to adjust the coaxiality of multiple groups. After the adjustment is completed, the adjusting part 21 is fixed and no longer moves, thereby preventing the adjusting part 21 from moving during subsequent use of the lens, which would cause the position of the adjusting group 22 to deviate and result in the coaxiality of multiple groups not meeting the optical design requirements.

[0040] Specifically, to ensure the fixation of the adjusting part 21 after adjustment, in one embodiment of this utility model, the lens adjustment structure further includes a locking structure. The locking structure is disposed in the housing 1 and connected to the adjusting part 21. The locking structure is used to lock the adjusting part 21 after it has adjusted the position of the adjusting group 22. With this configuration, during assembly, the adjusting part 21 drives the adjusting group 22 to move longitudinally and vertically. At this time, the locking structure will not lock the adjusting part 21, ensuring its normal operation. After the adjusting part 21 has finished adjusting, the locking structure locks it to restrict its movement, ensuring its fixation after adjustment and preventing movement that could affect the coaxiality of multiple groups.

[0041] It is understood that this utility model does not limit the specific structural form of the locking structure. For example, in one embodiment of this utility model, the locking structure can be set as a fastening bolt. The fastening bolt is threadedly connected to the housing 1, and one end is set towards the adjusting part 21. In this way, during the assembly process, when the adjusting part 21 drives the adjusting group 22 to move longitudinally and vertically, the fastening bolt is set away from the adjusting part 21 to ensure the normal operation of the adjusting part 21. After the adjusting part 21 is adjusted, the fastening bolt moves towards the adjusting part 21 until it presses against the adjusting part 21. Under the effect of thread self-locking, the fastening bolt can always maintain the clamping force on the adjusting part 21, so as to restrict the movement of the adjusting part 21 at all times, ensure the fixation of the adjusting part 21 after adjustment, and avoid the adjusting part 21 from moving after adjustment, thereby affecting the coaxiality of multiple groups.

[0042] Of course, in another embodiment of this utility model, the locking structure can also be set as an adhesive structure such as glue. In this embodiment, when the adjusting part 21 drives the adjusting group 22 to move in the longitudinal and vertical directions, the glue is not applied between the adjusting part 21 and the housing 1. After the adjusting part 21 is adjusted, the glue is applied between the adjusting part 21 and the housing 1 to bond the adjusting part 21 and the housing 1, ensuring the stability of the connection between the adjusting part 21 and the housing 1, thereby preventing the adjusting part 21 from moving after adjustment, which would affect the coaxiality of multiple groups.

[0043] Of course, in other embodiments of this utility model, the locking structure can also be set to other structures that can lock the adjusting part 21 after the adjusting part 21 has finished adjusting. In actual setting, it can be selected according to the requirements, and this utility model does not limit it.

[0044] Furthermore, this utility model does not limit the specific structural form of the adjusting part 21. In one embodiment of this utility model, the housing 1 has a first through hole 11 extending through at least one end in the transverse direction. The adjusting part 21 includes a drive guide rod 211 and a first eccentric wheel 212. The drive guide rod 211 is disposed in the housing 1 and is movably connected to the adjusting group 22. The first eccentric wheel 212 is rotatably disposed in the first through hole 11 along the transversely extending axis. The first eccentric wheel 212 is fixedly connected to the drive guide rod 211 and is eccentrically disposed with the drive guide rod 211 to drive the drive guide rod 211 to move in the longitudinal and vertical directions. With this configuration, when it is necessary to adjust the coaxiality of multiple groups, the first eccentric wheel 212 rotates along the laterally extending axis. Since the first eccentric wheel 212 and the drive guide rod 211 are eccentrically positioned, the first eccentric wheel 212 can drive the drive guide rod 211 to rotate along the laterally extending axis while simultaneously driving the drive guide rod 211 to move longitudinally and vertically. This causes the drive guide rod 211 to drive the alignment group 22 to move longitudinally and vertically, thereby adjusting the position of the alignment group 22 and thus adjusting the coaxiality of multiple groups inside the lens. The coaxiality of the multiple groups meets the optical design requirements during the assembly process.

[0045] Of course, in another embodiment of this utility model, the drive guide rod 211 can also be rotatably connected to the first eccentric wheel 212 along the horizontally extending axis, and is eccentrically set with the first eccentric wheel 212. In this way, when it is necessary to adjust the coaxiality of multiple groups, the first eccentric wheel 212 rotates along the horizontally extending axis. At this time, the first eccentric wheel 212 will not drive the drive guide rod 211 to rotate along the horizontally extending axis, but will directly drive the drive guide rod 211 to move in the longitudinal and vertical directions, thereby causing the drive guide rod 211 to drive the alignment group 22 to move in the longitudinal and vertical directions, so as to adjust the position of the alignment group 22, thereby adjusting the coaxiality of multiple groups inside the lens. The coaxiality of multiple groups meets the optical design requirements during the assembly process.

[0046] In another embodiment of this utility model, the adjusting part 21 can also be configured as other structures capable of driving the adjusting group 22 to move longitudinally and vertically. For example, in this embodiment, the adjusting part 21 includes a transmission rod and adjusting groups disposed in the longitudinal and vertical directions of the transmission rod. Each adjusting group includes two opposing elastic adjusting members. The transmission rod is connected to the adjusting group 22. With this configuration, when it is necessary to adjust the coaxiality of multiple groups, the multiple elastic adjusting members in the two adjusting groups extend or retract respectively to drive the transmission rod to move longitudinally and vertically. At this time, the transmission rod can drive the adjusting group 22 to move longitudinally and vertically, thereby adjusting the coaxiality of multiple groups.

[0047] Of course, in other embodiments of this utility model, the adjusting part 21 can also be configured as other structures that can drive the adjusting group 22 to move vertically and vertically. In actual configuration, it can be selected according to the requirements, and this utility model does not limit it.

[0048] It should be noted that when the drive guide rod 211 and the first eccentric wheel 212 are fixedly connected, it is also necessary to ensure the connection stability between the drive guide rod 211 and the first eccentric wheel 212. Therefore, in one embodiment of the present invention, the first eccentric wheel 212 is recessed at one end facing the drive guide rod 211 with a groove 213. A limiting part 215 is provided in the groove 213. The drive guide rod 211 is provided with a mating part 214 corresponding to the limiting part 215. The mating part 214 can extend into the groove 213 and cooperate with the limiting part 215. With this configuration, the mating part 214 extends into the groove 213 to engage with the limiting part 215, thereby fixing the relative position of the mating part 214 and the groove 213. This further fixes the relative position of the drive guide rod 211 and the first eccentric wheel 212, so that when the first eccentric wheel 212 rotates along the laterally extending axis, the drive guide rod 211 can rotate together with the first eccentric wheel 212.

[0049] Specifically, this utility model does not limit the specific structural form of the limiting part 215 and the mating part 214. In one embodiment of this utility model, the limiting part 215 can be set as a limiting surface, and the limiting surface and the groove 213 together form a D-shaped groove 213. The mating part 214 can be set as a D-shaped protrusion. With this configuration, the D-shaped protrusion can extend into the D-shaped groove 213 and cooperate with the D-shaped groove 213 and lock with each other, thereby ensuring that when the first eccentric wheel 212 rotates along the laterally extending axis, the drive guide rod 211 can rotate together with the first eccentric wheel 212.

[0050] In another embodiment of this utility model, the limiting part 215 can also be configured as a snap-fit ​​member, and the mating part 214 can also be configured as a snap-fit ​​block that can snap-fit ​​with the snap-fit ​​member. In this way, when the snap-fit ​​block extends into the groove 213, the snap-fit ​​block can snap-fit ​​with the snap-fit ​​member, thereby locking the two together to ensure that when the first eccentric wheel 212 rotates along the laterally extending axis, the drive guide rod 211 can rotate together with the first eccentric wheel 212.

[0051] Of course, this utility model does not limit the specific number of the first eccentric wheel 212. In one embodiment of this utility model, only one first eccentric wheel 212 is provided. The first eccentric wheel 212 is fixedly connected to one end of the drive guide rod 211 in the lateral direction and is eccentrically arranged with the drive guide rod 211. The other end of the drive guide rod 211 in the lateral direction is rotatably disposed on the housing 1 along the laterally extending axis.

[0052] In another embodiment of this utility model, the housing 1 has first through holes 11 at both ends along the lateral direction. Two first eccentric wheels 212 are provided, which are respectively disposed at both ends of the drive guide rod 211 along the lateral direction and extend laterally and are fixedly connected to the drive guide rod 211. Each eccentric wheel and the drive guide rod 211 are eccentrically arranged. With this arrangement, the two eccentric wheels can rotate simultaneously along a very long axis, thereby jointly driving the drive guide rod 211 to rotate together along the lateral axis. This can further ensure the stability of the first eccentric wheel 212 driving the drive guide rod 211 and improve the accuracy of the zoom lens adjustment system 100 in adjusting the coaxiality of multiple groups.

[0053] Furthermore, to ensure the accuracy of the extension angle of the core-aligning group 22 during its lateral movement, in one embodiment of this invention, the core-aligning structure 2 further includes a guide rod 23. The guide rod 23 extends laterally within the housing 1 and is movably connected to the core-aligning group 22. The guide rod 23 guides the lateral movement of the core-aligning group 22. With this configuration, when the core-aligning group 22 moves laterally, the guide rod 23 can limit the specific angle of movement of the core-aligning group 22, thereby preventing angular deviations from occurring during its lateral movement, which could affect the coaxiality between multiple groups.

[0054] Of course, other structural forms can also be used to guide the lateral movement of the core-aligning group 22. For example, in another embodiment of this utility model, the core-aligning structure 2 further includes a guide groove, which extends laterally within the housing 1 and is movably connected to the core-aligning group 22. The guide groove is used to guide the lateral movement of the core-aligning group 22. With this configuration, the guide groove can also limit the specific movement angle of the core-aligning group 22, thereby preventing angular deviations from occurring during lateral movement of the core-aligning group 22, which would affect the coaxiality between multiple groups.

[0055] It should be noted that when the adjusting part 21 drives the adjusting group 22 to move longitudinally and vertically, the position of the adjusting group 22 in the longitudinal and vertical directions will change. To indicate that interference occurs between the adjusting group 22 and the guide rod 23, in one embodiment of this utility model, the adjusting group 22 is provided with an elongated hole 221 extending laterally, and the guide rod 23 passes through the elongated hole 221 and can slide along the extension direction of the elongated hole 221. With this configuration, when the position of the adjusting group 22 changes in the longitudinal and vertical directions, the guide rod 23 will slide along the extension direction of the elongated hole 221, thereby adjusting its relative position with the adjusting group 22, so as to avoid mutual interference between the guide rod 23 and the adjusting group 22, which would affect the adjustment of the position of the adjusting group 22.

[0056] Of course, when the adjusting part 21 drives the adjusting group 22 to move longitudinally and vertically, in order to further ensure the stability of the movement of the adjusting group 22, a second driving source can be provided to drive the adjusting group together with the adjusting part 21. In this embodiment of the present invention, the housing 1 has a second through hole at least one end in the transverse direction, and the adjusting structure 2 also includes a second eccentric wheel. The second eccentric wheel is rotatably disposed in the second through hole in the transverse direction. The second eccentric wheel is fixedly connected to the guide rod 23 and is eccentrically disposed with respect to the guide rod 23, so as to drive the guide rod 23 to move longitudinally and vertically. With this configuration, when it is necessary to adjust the coaxiality of multiple groups, the second eccentric wheel can rotate along the transversely extending axis to drive the guide rod 23 to move longitudinally and vertically, thereby driving the adjusting group 22 to move longitudinally and vertically together with the adjusting part 21, so as to adjust the position of the adjusting group 22, thereby adjusting the coaxiality of multiple groups inside the lens. The coaxiality of multiple groups meets the optical design requirements during the assembly process.

[0057] Of course, this utility model does not limit the specific connection form of the guide rod 23 and the second eccentric wheel. The guide rod 23 and the second eccentric wheel can be rotatably connected or fixedly connected. In actual setting, the choice can be made according to the requirements. This utility model does not limit this.

[0058] Furthermore, since the first eccentric wheel 212 is rotatably disposed within the first through hole 11 along a laterally extending axis, to ensure that the first eccentric wheel 212 can rotate smoothly along the laterally extending axis during assembly, in one embodiment of this utility model, a rotating part is also provided at the end of the first eccentric wheel 212 away from the drive guide rod 211. The rotating part is used to drive the first eccentric wheel 212 to rotate along the laterally extending axis. With this configuration, when the first eccentric wheel 212 needs to rotate along the laterally extending axis, the operator can hold the rotating part to drive the first eccentric wheel 212 to rotate along the laterally extending axis through the rotating part, thereby ensuring the smoothness of the rotation of the first eccentric wheel 212.

[0059] Furthermore, after assembly, to prevent accidental contact with the rotating part, which could cause a change in the angle of the first eccentric wheel 212 and affect the coaxiality of multiple groups, in this invention, the first eccentric wheel 212 and the rotating part are detachably connected. When the first eccentric wheel 212 needs to rotate along a laterally extending axis, the rotating part connects to the first eccentric wheel 212 to drive it to rotate along the laterally extending axis. After the first eccentric wheel 212 has rotated, the connecting part disconnects from the first eccentric wheel 212 to disassemble the rotating part, preventing it from driving the first eccentric wheel 212 to rotate again after it has rotated. Then, the locking structure locks the first eccentric wheel 212 to determine its current rotation angle.

[0060] Of course, this utility model does not limit the specific structural form of the rotating part. In one embodiment of this utility model, the rotating part can be set as a rotating knob. The rotating knob is connected to the end of the first eccentric wheel 212 away from the drive guide rod 211. The operator rotates the rotating knob along the horizontally extending axis, thereby driving the first eccentric wheel 212 to rotate along the horizontally extending axis.

[0061] In another embodiment of this utility model, the first eccentric wheel 212 has an elongated groove recessed at one end away from the drive guide rod 211, and the two opposite ends of the elongated groove are connected. The rotating part includes a rotating plate. Thus, part of the rotating part can extend into the elongated groove and cooperate with the elongated groove to lock each other. By operating the elongated groove along the horizontally extending axis, the operator can drive the first eccentric wheel 212 to rotate synchronously along the horizontally extending axis.

[0062] In another embodiment of the present invention, the end of the first eccentric wheel 212 away from the drive guide rod 211 may also be recessed with a rectangular groove. The rotating part includes a screwing tool, part of which can extend into the rectangular groove and cooperate with the rectangular groove to limit the relative angle between the two. In this way, when the operator operates the screwing tool together, the first eccentric wheel 212 can be driven to rotate along the laterally extending axis.

[0063] Furthermore, to further ensure the coaxiality adjustment capability of the zoom lens adjustment system for multiple groups, in one embodiment of this invention, the housing 1 includes an inner shell and an outer shell spaced apart. The outer shell is fitted over the outer side of the inner shell, and the inner sidewall of the outer shell is provided with multiple telescopic members spaced apart circumferentially. These telescopic members collectively abut against the inner shell, and each telescopic member can extend or retract radially along the outer shell. The inner shell is provided with the adjusting part 21 and the adjusting group 22. With this configuration, during the adjustment of the adjusting group 22 by the adjusting part 21, the multiple telescopic members can further adjust the longitudinal and vertical positions of the adjusting group 22, thereby further improving the adjustment capability of the zoom lens adjusting system 100.

[0064] This utility model also proposes a zoom lens, which includes a zoom lens adjustment system 100. The specific structure of the zoom lens is as described in the above embodiments. Since this zoom lens adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
