When the focusing barrel rotates, it can drive the lens group to perform axial linear motion in the main barrel to achieve focusing or zooming action.
[0003] However, due to the gap between the lens group and the main tube, when the lens group moves axially in the main tube, the lens group will swing slightly around the axis of the screw, thereby causing the imaging picture of the lens to shake. Utility Model Content

[0005] The utility model also provides a lens and a camera device having the focusing assembly.
[0006] According to the first aspect of the present invention, the focusing assembly comprises: a lens group; a main barrel, which is sleeved outside the lens group, and the side wall of the main barrel is provided with a first axial guide groove and a second axial guide groove which are arranged at intervals along the circumference of the main barrel; a focusing barrel, which is sleeved outside the main barrel, and the side wall of the focusing barrel is provided with a first focusing groove corresponding to the first axial guide groove, and a second focusing groove corresponding to the second axial guide groove; a first guide member and a second guide member, the first guide member is passed through the first focusing groove and the first axial guide groove and is fixedly connected to the lens group, the second guide member is passed through the second focusing groove and the second axial guide groove and is fixedly connected to the lens group, the first axial guide groove limits the first guide member from moving along the circumference of the main barrel relative to the main barrel, and the second axial guide groove limits the second guide member from moving along the circumference of the main barrel relative to the main barrel, and a plane perpendicular to the axis of the lens group is defined as a reference plane, and the projection of the axis of the first guide member on the reference plane intersects with the projection of the axis of the second guide member on the reference plane;
[0007] The focusing barrel can be operably rotated around the axis of the focusing barrel to drive the lens group to perform axial linear motion through the first guide member and the second guide member.
[0008] The focusing assembly according to the embodiment of the utility model has at least the following beneficial effects:
[0009] In the focusing assembly of the utility model, when the focusing tube is operated to rotate around the axis of the focusing tube, the focusing tube drives the first guide member and the second guide member to move along the first focusing groove and the second focusing groove respectively, and the first guide member and the second guide member also move in the first axial guide groove and the second axial guide groove respectively. In this way, driven by the first guide member and the second guide member, the lens group can perform axial linear motion. Among them, the first axial guide groove limits the circumferential movement of the first guide relative to the main cylinder along the main cylinder, and the second axial guide groove limits the circumferential movement of the second guide relative to the main cylinder along the main cylinder 200. In this way, the first guide and the second guide are both restricted from moving relative to the main cylinder along the circumferential movement of the main cylinder. In addition, since the first guide and the second guide are both fixedly connected to the lens group, and since the axis of the first guide is not parallel to or coincides with the axis of the second guide, even if there is a gap between the outer wall of the lens group and the inner wall of the main cylinder, under the joint action of the first guide and the second guide, the lens group will not deflect around the axis of the first guide or the second guide, which can reduce the risk of tilting, swinging, etc. of the lens group, thereby improving the stability of imaging and improving the problem of imaging picture jitter during focusing or zooming.
[0010] According to some embodiments of the present invention, the first guide member and the second guide member are arranged opposite to each other, and an angle between a projection of an axis of the first guide member on the reference plane and a projection of an axis of the second guide member on the reference plane is greater than 0° and less than 10°.

[0012] According to some embodiments of the present invention, the angle between the first axial guide groove and the second axial guide groove is greater than 170°.
[0013] According to some embodiments of the present invention, the first guide member is in contact with and fits with two side walls of the first axial guide groove.
[0014] According to some embodiments of the present invention, the second guide member is in contact with and fits with two side walls of the second axial guide groove.
[0015] According to some embodiments of the utility model, the first guide member includes a first screw and a first guide member sleeved outside the first screw, the first guide member is inserted into the first focusing groove and the first axial guide groove, and the first screw is fixedly connected to the lens group.

[0017] The lens according to the embodiment of the second aspect of the utility model includes the focusing assembly as described above.
[0018] The lens according to the embodiment of the utility model has at least the following beneficial effects:
[0019] The lens of the present invention has the above-mentioned focusing assembly. In the focusing assembly, when the focusing barrel is operated to rotate around the axis of the focusing barrel, the focusing barrel drives the first guide member and the second guide member to move along the first focusing groove and the second focusing groove respectively, and the first guide member and the second guide member also move in the first axial guide groove and the second axial guide groove respectively. In this way, driven by the first guide member and the second guide member, the lens group can perform axial linear motion. Among them, the first axial guide groove limits the circumferential movement of the first guide relative to the main cylinder along the main cylinder, and the second axial guide groove limits the circumferential movement of the second guide relative to the main cylinder along the main cylinder 200. In this way, the first guide and the second guide are both restricted from moving relative to the main cylinder along the circumferential movement of the main cylinder. In addition, since the first guide and the second guide are both fixedly connected to the lens group, and since the axis of the first guide is not parallel to or coincides with the axis of the second guide, even if there is a gap between the outer wall of the lens group and the inner wall of the main cylinder, under the joint action of the first guide and the second guide, the lens group will not deflect around the axis of the first guide or the second guide, which can reduce the risk of tilting, swinging, etc. of the lens group, thereby improving the stability of imaging and improving the problem of imaging picture jitter during focusing or zooming.
[0020] The camera device according to the third aspect of the embodiment of the utility model includes the lens as described above.
[0021] The camera device according to the embodiment of the utility model has at least the following beneficial effects:
[0022] The video camera device of the utility model has the above-mentioned lens. In the focusing assembly of the lens, when the focusing barrel is operated to rotate around the axis of the focusing barrel, the focusing barrel drives the first guide member and the second guide member to move along the first focusing groove and the second focusing groove respectively, and the first guide member and the second guide member also move in the first axial guide groove and the second axial guide groove respectively. In this way, driven by the first guide member and the second guide member, the lens group can perform axial linear motion. Among them, the first axial guide groove limits the circumferential movement of the first guide relative to the main cylinder along the main cylinder, and the second axial guide groove limits the circumferential movement of the second guide relative to the main cylinder along the main cylinder 200. In this way, the first guide and the second guide are both restricted from moving relative to the main cylinder along the circumferential movement of the main cylinder. In addition, since the first guide and the second guide are both fixedly connected to the lens group, and since the axis of the first guide is not parallel to or coincides with the axis of the second guide, even if there is a gap between the outer wall of the lens group and the inner wall of the main cylinder, under the joint action of the first guide and the second guide, the lens group will not deflect around the axis of the first guide or the second guide, which can reduce the risk of tilting, swinging, etc. of the lens group, thereby improving the stability of imaging and improving the problem of imaging picture jitter during focusing or zooming.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a focusing assembly, which includes a lens group 100 , a main barrel 200 , a focusing barrel 300 , a first guide member 400 and a second guide member 500 .
[0040] The lens assembly 100 includes a plurality of lenses, which are coaxially arranged and assembled together through a bracket.
[0041] The main tube 200 is sleeved outside the lens assembly 100 .
[0042] Specifically, to facilitate assembly of the lens assembly 100 , the inner diameter of the main tube 200 is slightly larger than the outer diameter of the lens assembly 100 , that is, the main tube 200 is sleeved outside the lens assembly 100 , and a gap is left between the inner wall of the main tube 200 and the outer wall of the lens assembly 100 .
[0043] Furthermore, the side wall of the main cylinder 200 is provided with a first axial guide groove 210 and a second axial guide groove 220 which are arranged at intervals along the circumferential direction of the main cylinder 200 .
[0044] Specifically, the first axial guide groove 210 and the second axial guide groove 220 both extend along the axial direction of the main cylinder 200 , and the first axial guide groove 210 and the second axial guide groove 220 are spaced apart from each other along the circumferential direction of the main cylinder 200 .
[0045] The focusing tube 300 is sleeved outside the main tube 200 , and a first focusing groove 310 corresponding to the first axial guide groove 210 and a second focusing groove 320 corresponding to the second axial guide groove 220 are formed on a side wall of the focusing tube 300 .
[0046] Specifically, the first focusing groove 310 and the second focusing groove 320 both extend spirally, and the first focusing groove 310 and the second focusing groove 320 are symmetrically arranged, wherein the axis of the focusing barrel 300 is located in the symmetric plane of the first focusing groove 310 and the second focusing groove 320 .
[0047] The first guide member 400 is disposed through the first focusing groove 310 and the first axial guide groove 210 and is fixedly connected to the lens assembly 100 . The second guide member 500 is disposed through the second focusing groove 320 and the second axial guide groove 220 and is fixedly connected to the lens assembly 100 .
[0048] It can be understood that when the focusing barrel 300 is operated to rotate around the axis of the focusing barrel 300, the focusing barrel 300 drives the first guide member 400 and the second guide member 500 to move along the first focusing groove 310 and the second focusing groove 320 respectively, and the first guide member 400 and the second guide member 500 also move in the first axial guide groove 210 and the second axial guide groove 220 respectively. In this way, driven by the first guide member 400 and the second guide member 500, the lens group 100 can perform axial linear motion.
[0049] It should be noted that the axial position of the focusing barrel 300 is limited, that is, the focusing barrel 300 can rotate around the axis of the focusing barrel 300 relative to the main barrel 200, but is restricted from moving along the axial direction of the main barrel 200 relative to the main barrel 200. When the focusing barrel 300 rotates around the axis of the focusing barrel 300 relative to the main barrel 200, the focusing barrel 300 drives the first guide member 400 and the second guide member 500 to move along the first focusing groove 310 and the second focusing groove 320 respectively, so that the first guide member 400 and the second guide member 500 also move in the first axial guide groove 210 and the second axial guide groove 220 respectively, thereby driving the lens group 100 to perform axial linear motion.
[0050] It can be understood that the axial linear motion of the lens assembly 100 means that the lens assembly 100 only moves axially relative to the main tube 200 without rotating.
[0051] It can be understood that the top of the focusing barrel 300 can be limited at the top edge of the main barrel 200, and the bottom of the focusing barrel 300 can be supported by an elastic member, so that the focusing barrel 300 can rotate around the axis of the focusing barrel 300 relative to the main barrel 200, but is restricted from moving along the axial direction of the main barrel 200 relative to the main barrel 200.
[0052] Furthermore, the first axial guide groove 210 limits the circumferential movement of the first guide member 400 relative to the main cylinder 200 along the main cylinder 200, and the second axial guide groove 220 limits the circumferential movement of the second guide member 500 relative to the main cylinder 200 along the main cylinder 200; a plane perpendicular to the axis of the lens group 100 is defined as a reference plane, and the projection of the axis of the first guide member 400 on the reference plane intersects with the projection of the axis of the second guide member 500 on the reference plane, that is, the axis of the first guide member 400 and the axis of the second guide member 500 are neither parallel nor coincident.
[0053] Specifically, the first guide member 400 and the second guide member 500 are arranged opposite to each other, and the angle between the projection of the axis of the first guide member 400 on the reference plane and the projection of the axis of the second guide member 500 on the reference plane is greater than 0° and less than 10°.
[0054] It can be understood that the first guide member 400 and the second guide member 500 are respectively distributed on both sides of the main tube 200, and the angle between the projection of the axis of the first guide member 400 on the reference plane and the projection of the axis of the second guide member 500 on the reference plane is limited to between 0° and 10°, so that the force on both sides of the lens group 100 can be as uniform as possible, thereby improving the stability of the lens group 100 during axial linear motion.
[0055] In addition, it should be noted that, in order to coordinately arrange the first guide member 400 and the second guide member 500 at corresponding positions, the angle between the first axial guide groove 210 and the second axial guide groove 220 is less than 180°.
[0056] Furthermore, in order to satisfy that the angle between the projection of the axis of the first guide member 400 on the reference plane and the projection of the axis of the second guide member 500 on the reference plane is greater than 0° and less than 10°, the angle between the first axial guide groove 210 and the second axial guide groove 220 is greater than 170° and less than 180°.
[0057] Furthermore, the first guide member 400 contacts and cooperates with both side walls of the first axial guide groove 210 , so that the first axial guide groove 210 can limit the first guide member 400 and restrict the first guide member 400 from moving relative to the main cylinder 200 along the circumferential direction of the main cylinder 200 .
[0058] Furthermore, the second guide member 500 contacts and cooperates with the two side walls of the second axial guide groove 220 , so that the second axial guide groove 220 can limit the second guide member 500 and restrict the second guide member 500 from moving relative to the main cylinder 200 along the circumferential direction of the main cylinder 200 .
[0059] It can be understood that the first axial guide groove 210 restricts the first guide member 400 from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200, and the second axial guide groove 220 restricts the second guide member 500 from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200. In this way, the first guide member 400 and the second guide member 500 are both restricted from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200. In addition, since the first guide member 400 and the second guide member 500 are both fixedly connected to the lens assembly 100, and since the first The axis of the guide member 400 is neither parallel to nor coincident with the axis of the second guide member 500. Therefore, even if there is a gap between the outer wall of the lens group 100 and the inner wall of the main barrel 200, under the joint action of the first guide member 400 and the second guide member 500, the lens group 100 will not deflect around the axis of the first guide member 400 or the second guide member 500, which can reduce the risk of tilting, swinging, etc. of the lens group 100, thereby improving the stability of imaging and improving the problem of image jitter during focusing or zooming.
[0060] Combination Figure 3 and Figure 4 In some embodiments, the first guide member 400 includes a first screw 410 and a first guide member 420 sleeved outside the first screw 410, the first guide member 420 is penetrated through the first focusing groove 310 and the first axial guide groove 210, and the first screw 410 is fixedly connected to the lens group 100.
[0061] Specifically, the first guide member 420 is cylindrical, the first screw 410 is fixedly inserted into the first guide member 420, and the threaded section of the first screw 410 extends out of the first guide member 420; the side wall of the lens assembly 100 is provided with a first screw hole; the first guide member 420 is inserted into the first focusing groove 310 and the first axial guide groove 210, and the threaded section of the first screw 410 is inserted into the first screw hole. The first guide member 420 contacts the groove walls of the first focusing groove 310 and the first axial guide groove 210. When the first guide member 400 moves along the first focusing groove 310 and the first axial guide groove 210, the first guide member 420 plays a role in guiding and transmitting the action force, so that the first screw 410 is subjected to the action force and drives the lens assembly 100 to move axially in a straight line. At the same time, since the threaded column of the first screw 410 has external threads, the accuracy can be improved by sleeved the first guide member 420 outside the first screw 410 and making the first guide member 420 contact the groove walls of the first focusing groove 310 and the first axial guide groove 210.
[0062] Combination Figure 3 and Figure 5 Further, the second guide member 500 includes a second screw 510 and a second guide member 520 sleeved outside the second screw 510, the second guide member 520 is penetrated through the second focusing groove 320 and the second axial guide groove 220, and the second screw 510 is fixedly connected to the lens group 100.
[0063] Specifically, the second guide 520 is cylindrical, the second screw 510 is fixedly inserted into the second guide 520, and the threaded section of the second screw 510 extends out of the second guide 520; the side wall of the lens assembly 100 is provided with a second screw hole, the second guide 520 is inserted into the second focusing groove 320 and the second axial guide groove 220, and the threaded section of the second screw 510 is inserted into the second screw hole. The second guide 520 contacts the groove wall of the second focusing groove 320 and the second axial guide groove 220. When the second guide 500 moves along the second focusing groove 320 and the second axial guide groove 220, the second guide 520 plays a role in guiding and transmitting the action force, so that the second screw 510 receives the action force and drives the lens assembly 100 to move axially in a straight line. At the same time, since the threaded column of the second screw 510 has external threads, the accuracy can be improved by sleeved the second guide member 520 outside the second screw 510 and making the second guide member 520 contact the groove walls of the second focusing groove 320 and the second axial guide groove 220.
[0064] The utility model also provides a lens, comprising the above-mentioned focusing assembly.
[0065] The lens of the present invention has the above-mentioned adjustment component. In the focusing component, when the focusing barrel 300 is operated to rotate around the axis of the focusing barrel 300, the focusing barrel 300 drives the first guide member 400 and the second guide member 500 to move along the first focusing groove 310 and the second focusing groove 320 respectively, and the first guide member 400 and the second guide member 500 also move along the first axial guide groove 210 and the second axial guide groove 220 respectively. In this way, driven by the first guide member 400 and the second guide member 500, the lens group 100 can perform axial linear motion. The first axial guide groove 210 restricts the first guide member 400 from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200, and the second axial guide groove 220 restricts the second guide member 500 from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200. In this way, the first guide member 400 and the second guide member 500 are both restricted from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200. In addition, since the first guide member 400 and the second guide member 500 are both fixedly connected to the lens group 100, and since the first guide member The axis of the first guide member 400 and the axis of the second guide member 500 are neither parallel nor coincident. Therefore, even if there is a gap between the outer wall of the lens group 100 and the inner wall of the main barrel 200, under the joint action of the first guide member 400 and the second guide member 500, the lens group 100 will not deflect around the axis of the first guide member 400 or the second guide member 500, which can reduce the risk of tilting, swinging, etc. of the lens group 100, thereby improving the stability of imaging and improving the problem of image jitter during focusing or zooming.
[0066] The utility model also provides a camera device, comprising the above-mentioned lens.
[0067] The camera device of the present invention has the above-mentioned lens. In the focusing assembly of the lens, when the focusing barrel 300 is operated to rotate around the axis of the focusing barrel 300, the focusing barrel 300 drives the first guide member 400 and the second guide member 500 to move along the first focusing groove 310 and the second focusing groove 320 respectively, and the first guide member 400 and the second guide member 500 also move along the first axial guide groove 210 and the second axial guide groove 220 respectively. In this way, driven by the first guide member 400 and the second guide member 500, the lens group 100 can perform axial linear motion. The first axial guide groove 210 restricts the first guide member 400 from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200, and the second axial guide groove 220 restricts the second guide member 500 from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200. In this way, the first guide member 400 and the second guide member 500 are both restricted from moving relative to the main barrel 200 along the circumferential direction of the main barrel 200. In addition, since the first guide member 400 and the second guide member 500 are both fixedly connected to the lens group 100, and since the first guide member The axis of the first guide member 400 and the axis of the second guide member 500 are neither parallel nor coincident. Therefore, even if there is a gap between the outer wall of the lens group 100 and the inner wall of the main barrel 200, under the joint action of the first guide member 400 and the second guide member 500, the lens group 100 will not deflect around the axis of the first guide member 400 or the second guide member 500, which can reduce the risk of tilting, swinging, etc. of the lens group 100, thereby improving the stability of imaging and improving the problem of image jitter during focusing or zooming.
