[0033] As Figures 1-4 shown, an embodiment of the present utility model provides a lens vibration detection device, which includes a base 1, side plates 2 and a rotating plate 3. Among them, the base 1 is fixedly arranged on a vibration machine table 100, and the vibration machine table 100 is used to provide the vibration force required for detection. There are two side plates 2, and the two side plates 2 are arranged at intervals and perpendicular to the base 1. Both of the two side plates 2 are provided with a rotation mounting area, and the rotation mounting area is provided with a plurality of first mounting holes 21. The plurality of first mounting holes 21 are circumferentially distributed around the center of the rotation mounting area and are divided into two in each group. The number of the first mounting holes 21 is an even number greater than or equal to four. Two second mounting holes 31 are respectively arranged on the side surfaces of the rotating plate 3 corresponding to the two side plates 2. The rotating plate 3 is clamped between the two side plates 2, and the two second mounting holes 31 on each side surface of the rotating plate 3 can be aligned with any group of the first mounting holes 21 in the corresponding rotation mounting area. A fastener can pass through the aligned first mounting hole 21 and second mounting hole 31 to connect the rotating plate 3 and the side plate 2. The rotating plate 3 is used to mount a lens.

[0034] By arranging a plurality of first mounting holes 21 circumferentially distributed around the center of the rotation mounting area in the rotation mounting area of the lens vibration detection device, the second mounting holes 31 on each side surface of the rotating plate 3 can be selected to be aligned with any group of the first mounting holes 21, and the connection between the rotating plate 3 and the side plate 2 is realized through a fastener; and when the rotating plate 3 is selected to be aligned with any group of the first mounting holes 21, the rotation of the rotating plate 3 around the center of the rotation mounting area is realized, so that the lens can be vibration tested at different rotation angles at the same height, meeting the requirements of users for the test scenario.

[0035] In this embodiment, the first mounting hole 21 is a second through hole, an internal thread is arranged in the second mounting hole 31, the fastener is a screw, and the screw passes through the second through hole and is screwed with the internal thread to realize the connection between the rotating plate 3 and the side plate 2.

[0036] Optionally, the number of the first mounting holes 21 is set to eight. The eight first mounting holes 21 are evenly distributed circumferentially around the center of the rotation mounting area and are divided into four groups. Each group of the first mounting holes 21 includes two first mounting holes 21, and the connecting line of the centers of the two first mounting holes 21 in each group passes through the center of the rotation mounting area. By circumferentially and evenly distributing the eight first mounting holes 21, the rotating plate 3 can perform vibration tests on the lens in the horizontal direction, with a 45° forward tilt, a 45° backward tilt, and the vertical direction, meeting the user's requirements.

[0037] As Figures 2-3 shown, in order to further facilitate the operation of rotating the rotating plate 3, rotating shafts 32 are provided on both sides of the rotating plate 3, and a rotating hole 22 is provided at the center position of the rotation mounting area. The rotating shafts 32 are arranged in the rotating holes 22.

The operation is simple and convenient.

[0038] Furthermore, a rotating shaft hole is provided on the side face of the rotating plate 3, and the rotating shafts 32 are elastically mounted in the rotating shaft holes through elastic members. When installing the rotating plate 3, the rotating shafts 32 can be pushed to overcome the elastic force of the elastic members so that the rotating shafts 32 are retracted into the rotating shaft holes to prevent interference between the rotating shafts 32 and the side plate 2 and affect the assembly. After the rotating shafts 32 of the rotating plate 3 are aligned with the rotating holes 22, a part of the rotating shafts 32 automatically extends out of the rotating shaft holes and extends into the rotating holes 22 under the elastic force of the elastic members to realize the connection between the rotating shafts 32 and the rotating holes 22.

[0039] In this embodiment, the rotating hole 22 includes a counterbore with coincident axes and a first through hole opened at the bottom of the counterbore. The rotating shafts 32 are arranged in the counterbore and elastically abut against the bottom of the counterbore. When disassembling the rotating plate 3, the rotating shafts 32 can be pushed out of the counterbore through the first through hole without disassembling the side plate 2 to realize the disassembly of the rotating plate 3.

[0040] Optionally, the elastic member is a compression spring. The compression spring is arranged in the rotating shaft hole and elastically abuts between the bottom of the rotating shaft hole and the rotating shafts 32 so that the rotating shafts 32 can partially extend out of the rotating shaft hole under the elastic force of the compression spring.

[0041] Optionally, multiple rotation mounting areas are provided on both side plates 2 at intervals along the length direction of the side plates 2. The rotating plate 3 can be selectively installed in the rotation mounting areas of the side plates 2 to realize vibration detection at different angles at different heights.

[0042] As Figure 4As shown, optionally, the base 1 includes two base plates 11 which are spaced apart and arranged on the vibrating table 100, and two side plates 2 are respectively arranged on the two base plates 11.

[0044] Furthermore, when the side plate 2 is inserted into the groove 111, the side plate 2 and the base plate 11 can be connected by screws.

[0045] In this embodiment, referring again to Figures 1-2 , the rotating plate 3 is provided with a middle opening 33. The lens includes a lens body and a chip 200. The lens body is arranged on one end face of the rotating plate 3, and the chip 200 is arranged on the other end face of the rotating plate 3, and the lens body, the middle opening 33 and the chip 200 are coaxially arranged, so that the rotating plate 3 can install the lens body and the chip 200 at the same time, and the installation structure is reasonable.

[0046] Furthermore, three inner side walls of the middle opening 33 are all provided with protruding columns 331, and the protruding columns 331 are provided with first threaded holes 3311. The lens body is installed on the rotating plate 3 by screwing with the first threaded holes 3311; the end face of the rotating plate 3 facing the chip 200 is provided with second threaded holes 34, and the chip 200 is connected to the rotating plate 3 by screwing with the second threaded holes 34.
