As shown in fig. 1 and 2, according to an aspect of the present application, there is provided a lens assembly 100, the lens assembly 100 includes a lens barrel 10 and a clip structure 20 for mounting a filter 60, the clip structure 20 includes a first arc member 21 and a second arc member 22, the first arc member 21 is fixed to or integrally formed with one end of the lens barrel 10, one end of the second arc member 22 is hinged to one end of the first arc member 21, for example, by a hinge shaft 90 shown in fig. 1, and the other end of the second arc member 22 is detachably connected to the other end of the first arc member 21.

In the lens assembly 100 provided in the present application, a conventional lens 70 is mounted in the lens barrel 10 for normal photographing. When the filter 60 is not needed, the filter 60 may not be disposed within the yoke structure 20.

When the filter 60 is required to be installed, the filter 60 can be clamped between the first arc-shaped member 21 and the second arc-shaped member 22. Compared with the scheme that the filter is clamped on the lens barrel by the clamping piece adopted in the prior art, the clamping structure 20 and the lens barrel 10 are reliably connected because the first arc-shaped piece 21 is fixed (for example, welded and screwed) or integrally formed on the lens barrel 10 and the second arc-shaped piece 22 is hinged to the first arc-shaped piece 21. Therefore, after the first arc-shaped member 21 and the second arc-shaped member 22 are fastened, the reliability of mounting the filter 60 on the clip structure 20, and thus the reliability of mounting the filter 60 on the lens barrel 10, can be ensured. Like this, when being applied to unmanned aerial vehicle with this lens subassembly 100, even if unmanned aerial vehicle takes place high-frequency vibration in the motion process, also do benefit to the reliability of guaranteeing filter 60 installation.

In addition, the filter 60 is mounted on the lens barrel 10 by the clip structure 20, so that the filter 60 is convenient to mount and dismount, and the filter 60 can be replaced quickly.

In order to further improve the reliability of the mounting of the clamping band structure 20 to the filter 60, as shown in fig. 1 and 2, in an embodiment of the present application, the inner wall of the first arc-shaped part 21 is provided with a first groove 211 extending along the circumferential direction thereof, the inner wall of the second arc-shaped part 22 is provided with a second groove 221 extending along the circumferential direction thereof, and the first groove 211 and the second groove 221 are used for accommodating the outer circumference of the filter 60. When installed, the outer periphery of the filter 60 is received within the first and

second recesses

211, 221. Here, the first and

second grooves

211 and 221 ensure the reliability of the installation of the filter 60, and also play a role in positioning, facilitating the quick installation of the filter 60 on the band structure 20.

It is understood that the first groove 211 may or may not extend through the first arc-shaped part 21 in the circumferential direction, and the present application is not limited thereto. When the first recess 211 does not penetrate in the circumferential direction of the first arc 21, it can be used in the case where the filter 60 is irregular. For example, the filter 60 includes a circular portion and two protrusions formed on the outer periphery of the circular portion, and when mounted, the two protrusions of the filter 60 may be mounted in the first and

second grooves

211 and 221, respectively, and the outer periphery of the other portion of the circular portion may contact the portion of the inner wall of the band structure 20 where the first and

second grooves

211 and 221 are not formed, respectively.

In one embodiment of the present application, as shown in fig. 1, the first recess 211 extends through the first arc-shaped member 21 in the circumferential direction, and the second recess 221 extends through the second arc-shaped member 22 in the circumferential direction, and when the second arc-shaped member 22 is located at a position to be engaged with the first arc-shaped member 21, the first recess 211 and the second recess 221 are configured as a continuous annular groove. The first and

second grooves

211 and 221 are configured as annular grooves capable of receiving the entire outer peripheral edge of the filter 60, and therefore, the mounting reliability of the band structure 20 to the filter 60 can be further improved.

The existing clamping mode of the clamping piece also has the problem of poor sealing performance between the filter lens and the lens cone, and when the lens is in moist and rainy days, moisture enters the inside of the lens cone to damage the lens and influence the service life of the lens in the lens cone.

In view of this, as shown in fig. 1 and 2, in an embodiment of the present application, the lens assembly 100 further includes a first sealing strip 30 and a second sealing strip 40, the first sealing strip 30 is embedded in the first groove 211, and the second sealing strip 40 is embedded in the second groove 221. The first sealing strip 30 and the second sealing strip 40 are arranged to hermetically connect the filter 60 and the clamp structure 20, so that the sealing performance between the filter 60 and the lens barrel 10 is ensured. The water vapor can be prevented from entering the lens barrel 10, the fogging of the lens 70 caused by temperature change can be avoided, and the damage of the water vapor to the lens 70 can be avoided. Meanwhile, dust can be prevented from entering the inside of the lens barrel 10. Moreover, the sealing strip allows to close the installation manufacturing tolerances, avoiding rigid contact of the filter 60 with the first arc 21 and the second arc 22.

Further, as shown in fig. 1 and 2, the first sealing tape 30 and the second sealing tape 40 are each provided with a slot 50 for receiving the outer periphery of the filter 60. That is, the first sealing tape 30 and the second sealing tape 40 are each U-shaped in cross section. The arrangement of the slot 50 facilitates the installation of the filter 60, and also facilitates the improvement of the sealing effect between the filter 60 and the two sealing strips.

As shown in fig. 1, in one embodiment of the present application, first recess 211 extends through in the circumferential direction of first arcuate member 21, and second recess 221 extends through in the circumferential direction of second arcuate member 22. Both ends of the first sealing strip 30 protrude out of both ends of the first groove 211 or both ends of the second sealing strip 40 protrude out of both ends of the second groove 221, so that both ends of the first sealing strip 30 and both ends of the second sealing strip 40 are pressed against each other when the first arc-shaped member 21 and the second arc-shaped member 22 are buckled. Thus, after the filter 70 is mounted in place, the two ends of the first sealing strip 30 and the two ends of the second sealing strip 40 are mutually extruded, so that the sealing performance of the connecting positions of the first arc-shaped part 21 and the second arc-shaped part 22 is ensured, and the sealing performance between the filter 60 and the lens barrel 10 is ensured.

Optionally, in an embodiment of the present application, the first sealing tape 30 is bonded to the first groove 211, and the second sealing tape 40 is bonded to the second groove 221, so as to ensure the reliability of the installation of the first sealing tape 30 in the first groove 211 and the reliability of the installation of the second sealing tape 40 in the second groove 221.

In other embodiments of the present application, the first sealing strip 30 can be embedded in the first groove 211 with a tight fit therebetween. Similarly, the second sealing strip 40 may be embedded in the second groove 221 with a tight fit therebetween.

In the embodiment of the present application, the separable connection between the other end of the first arc-shaped part 21 and the other end of the second arc-shaped part 22 can be realized in any suitable manner.

As shown in fig. 1 and 2, in one embodiment of the present application, one of the first arc-shaped part 21 and the second arc-shaped part 22 is provided with a latch 212, and the other is provided with a catch 222 for cooperating with the latch 212. For example, as shown in fig. 1, the first arc-shaped part 21 is provided with a latch 212, and the second arc-shaped part 22 is provided with a catch 222. Of course, in other embodiments, a latch may be provided on the second arc-shaped part 22 and a catch may be provided on the first arc-shaped part 21. The latch 212 and the latch 222 are matched, so that locking and unlocking operations are convenient, and quick mounting and dismounting of the filter 60 are facilitated.

In other embodiments of the present application, the other end of the first arc member 21 and the other end of the second arc member 22 can be screwed. For example, through holes are formed in the first arc-shaped part 21 and the second arc-shaped part 22, one end of a bolt sequentially penetrates through the through holes in the two arc-shaped parts, and the two arc-shaped parts are fixed by nuts.

In order to avoid the clip structure 20 from affecting the shooting of the lens 70, in an embodiment of the present application, the aperture of the annular hole defined by the first arc-shaped member 21 and the second arc-shaped member 22 may be made not smaller than the aperture of the lens barrel 10, so as to avoid the clip structure 20 from limiting the size of the shooting window of the lens 70 as much as possible.

As shown in fig. 1 and 2, the lens assembly 100 further includes a connection sleeve 80 connected to or integrally formed at the other end of the lens barrel, the connection sleeve 80 being used to mount the lens assembly 100 to a corresponding device.
