In summary, in the lens supporting device provided by the embodiment of the invention, the lens supporting device comprises the first bracket and the second bracket, the two brackets are rotationally connected, the first adjusting component comprises the first rotating piece, the first rotating piece is rotationally connected with the second bracket, and the first rotating piece is clamped on the first bracket, so that when the first rotating piece rotates, the relative position of the first rotating piece and the first bracket is unchanged due to the clamping of the first bracket, and the second bracket is driven to rotate around the rotating shaft rotationally connected with the two brackets, thereby realizing the rotation displacement change of the second bracket and finally realizing the rotation displacement change of a lens arranged on the lens supporting device.
Example 2:
further, please refer to fig. 2-1, which illustrates a schematic structural diagram of another lens supporting device according to an embodiment of the present invention, wherein more preferable components are added to the lens supporting device shown in fig. 1, so that the lens supporting device according to the embodiment of the present invention has better performance.
The lens support device further comprises: a base 15 and a second adjustment assembly 16.
The second adjusting assembly 16 includes a second rotating member 161 and a rotating hole 162 disposed on the first bracket 11, where one end of the second rotating member 161 is clamped to the base 15, and the other end extends into the rotating hole 162 of the first bracket 11 and rotates relatively, and a direction of a rotation axis D2 (coinciding with m1-m 2) of the second rotating member 161 is parallel to a direction of the rotation axis D1 of the first rotating member 11. Thus, an operator can rotate the two rotating parts from the same direction, and the adjustment of the lens position is facilitated.
The second rotating member 161 can rotate on the base 15 around the axis D2 of the second rotating member 161 and is limited by the clamping connection of the base 15 during rotation, and the relative position of the second rotating member 161 and the base 15 is unchanged, so that the first bracket 11 rotationally connected with the second rotating member 161 is driven to move along the axis D2 of the second rotating member 161, and then the lens 20 in the lens frame is driven to move along the axis D2 of the second rotating member 161.
Alternatively, the first rotating member 141 or the second rotating member 161 is a screw, and the second bracket 12 or the first bracket 11 is provided with a screw thread in a rotating hole. When the first rotating member 141 is a screw, the threads on the screw are matched with the threads in the rotating hole of the second bracket 12, so that the second bracket 12 can be driven to rotate when the first rotating member 141 rotates. When the second rotating member 161 is a screw, the screw thread on the screw is matched with the screw thread in the rotating hole of the first bracket 11, so that the first bracket 11 can be driven to move when the second rotating member 161 rotates.
In addition, the base 15 may further be provided with an adjusting opening C1 and an adjusting opening C2, where the adjusting opening C1 and the adjusting opening C2 are communicated with the outside of the base 15, so that an operator can conveniently adjust the first rotating member 141 and the second rotating member 161 from the outside of the base 15 to adjust the position of the lens 20.
The lens 20 may be a single lens or a lens group including a plurality of lenses.
The second adjusting component in the lens supporting device provided by the embodiment of the invention has the advantages of simple structure, easiness in operation, high repairability, capability of finishing the position adjustment of the lens by rotating the second rotating piece in situ, small space required by the second adjusting component, easiness in arrangement in the lens supporting device and high adjusting precision.
When the lens supporting device is applied to a projection product light path, the lens supporting device and the lens are assembled in the structure body, and when the position of the lens is required to be debugged, the position of the inner lens can be adjusted only by rotating the first rotating piece or the second rotating piece exposed out of the adjusting opening without disassembling the structure body.
Meanwhile, the first rotating piece or the second rotating piece does not generate relative displacement change relative to the position where the first rotating piece or the second rotating piece is adjusted, namely, the rotation in and rotation out change does not occur, so that the thickness of the shell where the first rotating piece or the second rotating piece is positioned does not need to be thickened to meet the length of the inlet and outlet path of the first rotating piece or the second rotating piece, and the appearance is always kept smooth.
As shown in fig. 2-2, the first bracket 11 is provided with a clamping groove 111, one end of the first rotating member 141 is provided with an annular limiting rib 1411, the first rotating member 141 is clamped in the clamping groove 111 through the annular limiting rib 1411, the clamping of the first rotating member 141 and the first bracket 11 is realized, the structure is simple, the implementation is easy, and the stability is higher. The annular stopper 1411 may be provided with an annular groove whose opening direction is a direction away from the axis D1 of the first rotary member 141.
The first rotating member 141 is limited to be clamped with the first bracket 11 when rotating around the axis D1, and the relative position of the first bracket 11 is unchanged, but the second bracket 12 rotationally connected with the first rotating member 141 is driven by the first rotating member 141 to rotate around the rotating shaft rotationally connected with the first rotating member 11 and the second rotating member 12, and the position of the lens frame on the second bracket 12 is changed, which can mainly be represented as a change in the left-right direction of fig. 2-1. Wherein the first rotating member 141 may be a screw, and the rotating hole 142 may be provided therein with threads.
The first adjusting component in the lens supporting device provided by the embodiment of the invention has the advantages of simple structure, easiness in operation, high repairability, capability of finishing the position adjustment of the lens by rotating the first rotating piece in situ, small space required by the first adjusting component, easiness in arrangement in the lens supporting device and high adjusting precision.
When the first rotating member 141 is rotated, the position of the first rotating member 141 in the clamping groove 111 can be adjusted (the first rotating member 141 is moved in the clamping groove 111 along the direction perpendicular to the axis D1) so as to cooperatively adjust the position of the lens frame. In addition, when the first rotating member 141 is rotated to rotate the second bracket 12, the first bracket 11, the second bracket 12 and the first rotating member 141 may be elastically deformed, which may not damage the entire lens supporting device since the adjustment of the lens position is generally small.
As shown in fig. 2-3, which is a top view of the card slot 111 in fig. 2-2, 11 is a first bracket.
As shown in fig. 2-4, which is a schematic cross-sectional view of the lens supporting device shown in fig. 2-1 at m1-m2, a clamping groove 151 is provided on the base 15, an annular limiting rib 1611 is provided at one end of the second rotating member 161, and the second rotating member 161 is clamped in the clamping groove 151 through the annular limiting rib 1611, so that the clamping between the second rotating member 161 and the base 15 is realized, the structure is simple, the implementation is easy, and the stability is high. The annular stopper rib 1611 may be provided with an annular groove, and an opening direction of the annular groove is a direction away from the axis D2 of the second rotating member 161. C2 is the adjustment opening. The second rotating member 161 has a specific structure similar to that of the first rotating member 141.
In fig. 2-4, z is the rotational axis of the rotational connection of the first bracket 11 and the second bracket 12, and the rotational axis z is parallel to the axis y of the lens 20 in the lens frame 121. This facilitates adjustment of the position of the lens 20 by relative rotation of the first bracket 11 and the second bracket 12. The rotational axis z is perpendicular to the axis of the first rotational member (not shown in fig. 2-4). This facilitates the relative rotation of the first and second brackets 11, 12 by rotating the first rotating member.
Further, the rotation axes z of the first and second brackets 11 and 12 do not coincide with the optical axis y of the lens 20. Thus, when the first bracket 11 and the second bracket 12 rotate relatively, the lens 20 rotates asymmetrically, so that the position of the lens 20 is adjusted, and the adjustment can be reflected in the adjustment in the left-right direction in fig. 2-1.
It should be noted that, when the second rotating member 161 is rotated, the position of the second rotating member 161 in the clamping groove 151 may be adjusted (the second rotating member 161 is moved in the clamping groove 151 along a direction perpendicular to the axis D2 and parallel to the optical axis y) so as to drive the second bracket 12 to move in the direction of the axis y of the lens 20, thereby increasing the adjustable direction of one lens 20.
