That is, the first connection portion 1211 and the second connection portion 1212 are coaxially and fixedly connected, the first connection portion 1211 may have a first sub-screw hole, the second connection portion 1212 may have a second sub-screw hole thereon, and inner diameters of the first sub-screw hole and the second sub-screw hole may be the same, which may constitute the first screw hole k1.

The first end a1 of the connecting element 121 may be an end of the first connecting portion 1211 facing away from the second connecting portion 1212, the second end a2 of the connecting element 121 may be an end of the second connecting portion 1212 facing away from the first connecting portion 1211, and the first connecting portion 1211 may be thinner than the second connecting portion 1212.

The housing 21 of the optical device may have a first mounting hole k3 thereon, and the first mounting hole k3 may have a hole diameter larger than the outer diameter of the first connection portion 1211 and smaller than the outer diameter of the second connection portion 1212.

When the second end a2 of the connection member 121 is connected with the housing 21 of the optical device, the second connection portion 1212 may be located outside the first mounting hole k 3. In this case, there may be an effect in that, in the first aspect, the second connection portion 1212 may be located outside the first mounting hole k3 as compared to when the second end a2 of the connection member 121 is connected with the housing 21 of the optical device, and when the first end a1 of the connection member 121 is connected with the housing 21 of the optical device, the first connection portion 1211 may be located in the first mounting hole k3, the height of the connection member 121 on the housing 21 of the optical device may be reduced, that is, the distance between the connection member 121 and the lens mounting bracket 11 may be increased, so that the adjustment member 123 adjusts the distance between the connection member 121 and the lens mounting bracket 11. On the other hand, the first mounting hole k3 may play a role of positioning and mounting the first connection portion 1211, so that the connection of the connection member 121 and the housing 21 of the optical device is stable.

In other words, the two mounting manners of the adjusting member 123 enable the adjusting member 123 to have two different heights with respect to the housing 21 of the optical device, when the first end a1 of the connecting member 121 is connected with the housing 21 of the optical device, the first connecting portion 1211 is located in the first mounting hole k3 so that the height of the adjusting member 123 is lower, an adjusting space can be reserved for the lens mounting bracket 11, and when the second end a2 of the connecting member 121 is connected with the housing 21 of the optical device, the second connecting portion 1212 is located outside the first mounting hole k3 so that the height of the adjusting member 123 is higher, and at this time, the adjusting member 123 can directly abut against the lens mounting bracket 11 so that the connection of the lens mounting bracket 11 is more stable.

Referring to fig. 12, in an alternative embodiment, the housing 21 of the optical device may further have a first mounting groove k4 thereon, and the first mounting hole k3 may be located at a groove bottom of the first mounting groove k4, and a diameter of the first mounting groove k4 is greater than an outer diameter of the second connection portion 1212. The front projection of the first mounting groove k4 on the housing 21 of the optical device may be circular, and the first mounting hole k3 may be concentric with the first mounting groove k 4.

When the first end a1 of the connection member 121 is connected with the housing 21 of the optical device, the first connection portion 1211 may be positioned in the first mounting hole k3, and at least part of the second connection portion 1212 is positioned in the first mounting groove k 4. When the second end a2 of the connection member 121 is connected with the housing 21 of the optical device, at least part of the second connection portion 1212 may be located in the first mounting groove k4, and the first connection portion 1211 is located outside the first mounting groove k 4. The first mounting groove k4 can play a role in positioning and mounting the second connecting portion 1212 to further stabilize the connection of the connecting member 121 and the housing 21 of the optical device, and can improve the assembly accuracy of the connecting member 121 and the housing 21 of the optical device.

Referring to fig. 3 and 4, in an alternative embodiment, a side of the lens mounting bracket 11 adjacent to the connection member 121 may have an annular protrusion t1, the annular protrusion t1 may be located outside the first through hole k2, and an inner diameter of the annular protrusion t1 may be greater than an inner diameter of the first connection portion 1211. When the second end a2 of the connection member 121 is connected with the housing 21 of the optical device, the first connection portion 1211 of the connection member 121 may be located inside the annular protrusion t 1. In this way, after the connecting piece 121 abuts against the lens mounting bracket 11, the connecting piece 121 can be prevented from moving relative to the lens mounting bracket 11 in the axial direction perpendicular to the first screw hole k1 of the connecting piece 121, and the connection stability between the connecting piece 121 and the lens mounting bracket 11 can be improved.

Referring to fig. 7 and 8, in an alternative embodiment, the connection structure 12 may further include a second screw 124, and the housing 21 of the optical device has a second through hole k5 corresponding to the first screw hole k1. The second through hole k5 may be coaxial with the first mounting hole k3, and in this case, the first mounting hole k3 may be a through hole. The second screw 124 may pass through the second through hole k5 and be screw-coupled with the second end of the first screw hole k1 of the connection member 121 or screw-coupled with the first end of the first screw hole k1 of the connection member 121. The second screw 124 may be used to fixedly connect the housing 21 of the optical device and the connection member 121. Wherein, the second through hole k5 can be located at the bottom of the housing 21 of the optical device, so that the connecting piece 121 can be fixed at the bottom of the housing 21 of the optical device, so that the first screw 1231 can be adjusted from the upper opening of the housing 21 of the optical device, thereby reducing the adjustment difficulty of the lens mounting assembly 10.

Referring to fig. 2, the lens mounting bracket 11 may include an adjusting piece 111 and a mounting frame 112, the mounting frame 112 has a lens mounting surface m1, the adjusting piece 111 is connected to a side surface of the mounting frame 112, and a plane of the adjusting piece 111 intersects the lens mounting surface m 1. The first through hole k2 may be located in the adjustment sheet 111 to avoid the connection structure 12 from affecting the light entering and exiting the lens.

It should be noted that, the connection between one end of the elastic member 122 and the lens mounting bracket 11 may be in various connection manners, for example, may be a fixed connection, or may be an abutting connection, and similarly, the connection between the other end of the elastic member 122 and the connecting member 121 or the housing 21 of the optical device may be in various connection manners, for example, may be a fixed connection, or may be an abutting connection. The connection of the two ends of the elastic member 122 serves to limit the movement of the two ends of the elastic member 122, and illustratively, the connection of the two ends of the elastic member 122 serves to limit the extension of the elastic member 122 when the elastic member 122 is in a compressed state and the connection of the two ends of the elastic member 122 serves to limit the contraction of the elastic member 122 when the elastic member 122 is in a stretched state.

For example, when the elastic member 122 is in a compressed state, one end of the elastic member 122 may abut against the lens mounting bracket 11, and the other end may abut against the connection member 121 or the housing 21 of the optical device.

Referring to fig. 3 and 7, in an alternative embodiment, the elastic member 122 may include a first spring 1221, where the first spring 1221 is sleeved outside the second connection portion 1212. When the first end a1 of the connection member 121 is connected with the housing 21 of the optical device, one end of the first spring 1221 may abut the lens mounting bracket 11, and the other end of the first spring 1221 may abut the housing 21 of the optical device.

In making the adjustment by the lens mounting assembly 10, the first screw 1231 can be rotated to make the up and down adjustment of the lens in the lens mounting bracket 11. Specifically, the first spring 1221 may be in a compressed state, and when the first screw 1231 is rotated, the first screw 1231 may be screwed into the first screw hole k1 in the connection member 121 or unscrewed from the first screw hole k1 in the connection member 121. When the first screw 1231 is screwed into the first screw hole k1 in the connection member 121, a pressure may be applied to the adjustment sheet 111, and the adjustment sheet 111 transmits the pressure to the first spring 1221 and compresses the first spring 1221; when the first screw 1231 is screwed out of the first screw hole k1 in the connecting member 121, the first spring 1221 is elongated under its own elastic force, and the adjustment piece 111 can be moved away from the connecting member 121 by the urging force applied when the first spring 1221 is elongated.

Referring to fig. 3, for example, when the first end a1 of the connecting member 121 is connected to the housing 21 of the optical device, an end of the first spring 1221 near the lens mounting bracket 11 may be sleeved on the outer side of the annular protrusion t1 of the lens mounting bracket 11 to improve the stability of the first spring 1221.

Referring to fig. 2, in an exemplary embodiment, the lens mounting bracket 11 may have a plurality of first through holes k2 thereon, and the lens mounting assembly 10 may include a plurality of connection structures 12, through which the lens mounting bracket 11 may be connected with the housing 21 of the optical device. In this way, the position, and/or attitude, of the lens mounting bracket 11 inside the housing 21 of the optical device can be adjusted by the plurality of connection structures 12.

For example, the lens mounting bracket 11 may have three first through holes k2 thereon, and the lens mounting assembly 10 may include three connection structures 12, wherein the lens mounting bracket 11 may have a first adjustment plate 111, a second adjustment plate 111, and one mounting frame 112, the first adjustment plate 111 and the second adjustment plate 111 may be located at both sides of the mounting frame 112, respectively, two of the three through holes may be located at the first adjustment plate 111, and another of the three through holes may be located at the second adjustment plate 111. In the assembly process of the lens mounting bracket 11, the mounting manner of the two first through holes k2 on the first adjusting piece 111 and the first screws 1231 and the connecting piece 121 is a fixed mounting manner, that is, two ends of the connecting piece 121 can respectively abut against the housing 21 of the optical device and the first adjusting piece 111, and the two first screws 1231 connected with the first adjusting piece 111 are in a fixed state. The mounting manner of the first through hole k2 on the second adjusting plate 111 and the first screw 1231 and the connecting piece 121 is an adjustable mounting manner, that is, the first end a1 of the connecting piece 121 is connected with the housing 21 of the optical device, the second end a2 of the connecting piece 121 may have a space with the lens mounting bracket 11, the first screw 1231 may be connected with the second end a2 of the connecting piece 121 and the lens mounting bracket 11, respectively, and the first screw 1231 connected with the second adjusting plate 111 is in an adjustable state, so that the distance between the connecting piece 121 and the lens mounting bracket 11 is adjusted by the first screw 1231.
