Description

Technical Field

[0001] This invention relates to the field of piezoelectric fast-reflecting mirrors, and more specifically to a novel hinged closed-loop high-reliability piezoelectric fast-reflecting mirror. Background Technology

[0002] A piezoelectric fast-reflecting mirror is a rapid micro / nano angle positioning mechanism that uses piezoelectric ceramics as a driving source to control the direction of a light beam. It combines high-precision angle measurement technology, micro-displacement driving technology, and advanced control theory, significantly improving pointing control accuracy, control bandwidth, and angular resolution compared to traditional frame structures. Also commonly called a deflector or precision aiming mirror, it is an important component in optical positioning and scanning systems. Its moving surface has a clamping mechanism for mounting and fixing the load, allowing for micro-angle adjustment of the load. It can be integrated into various high-precision equipment, providing micro-radius-level motion control and optical path control. Existing technologies, such as the high-reliability piezoelectric deflector for aerospace applications (application number 202110486560.2), provide a piezoelectric deflector with enhanced mechanical properties, but are not suitable for providing a hinged closed-loop structure. The piezoelectric fast-reflecting mirror adopts a hinged closed-loop structure, forming a unified whole, which is less prone to damage and improves stability and reliability during use.

Detailed Implementation

[0034] A novel hinged closed-loop high-reliability piezoelectric fast-reflecting mirror includes a hinged closed-loop piezoelectric fast-reflecting mirror 101, a base 105, and a housing 201. Multiple screws I 102 are evenly distributed circumferentially on the outer side of the hinged closed-loop piezoelectric fast-reflecting mirror 101. A display plate 202 is fixedly connected to the top of the housing 201. Multiple upwardly protruding connecting seats 203 are evenly distributed circumferentially on the display plate 202. The screws I 102 pass through the outer edge of the hinged closed-loop piezoelectric fast-reflecting mirror 101 and are installed onto the corresponding connecting seats 203, thus simultaneously fixing the hinged closed-loop piezoelectric fast-reflecting mirror 101 onto the display plate 201. 2. The bottom of the outer shell 201 is fixedly connected to the base 105. A support rod 104 is fixedly connected to the middle of the base 105. The top of the support rod 104 extends into the hinged closed-loop piezoelectric fast-reflecting mirror 101. A screw II 103 is installed on the top of the support rod 104. A disc spring 106 is sleeved in the middle of the screw II 103. The lower side of the disc spring 106 contacts the inner side of the middle of the hinged closed-loop piezoelectric fast-reflecting mirror 101. Four piezoelectric ceramic components 401 are evenly arranged along the circumferential direction on the upper surface of the middle of the base 105. The four piezoelectric ceramic components 401 are evenly placed in the outer shell 201 along the circumferential direction.

[0035] This section is based on Figure 1-16The working process described is as follows: To facilitate the provision of a novel hinged closed-loop piezoelectric fast reflector with high reliability, during the use of the piezoelectric fast reflector, when a light beam irradiates the upper surface of the hinged closed-loop piezoelectric fast reflector 101, the two piezoelectric ceramic components 401 on either side (front, back, left, or right) at any desired position can be energized. This causes the piezoelectric ceramic components 401 on both sides to push the bottom surface of the hinged closed-loop piezoelectric fast reflector 101, causing the surface of the hinged closed-loop piezoelectric fast reflector 101 to tilt at an angle, thereby adjusting the angle at which the light beam is refracted. The light beam is then refracted within the hinged closed-loop piezoelectric fast reflector 101. During angle adjustment, the disc spring 106, which is sleeved in the middle of the screw II 103, will simultaneously undergo directional compression. Therefore, through the elasticity of the disc spring 106, the hinge closed-loop piezoelectric quick-reflecting mirror 101 is adjusted to the original position by providing a restoring force. Furthermore, under the overall enclosure of the housing 201 and the base 105, the hinge closed-loop piezoelectric quick-reflecting mirror 101 located above the housing 201 is more stable and reliable. The hinge closed-loop piezoelectric quick-reflecting mirror 101 adopts a hinge closed-loop structure and forms a whole, which is not easy to be damaged and improves the stability and reliability when using the quick-reflecting mirror.

[0036] The upper side of the display board 202 is provided with a protective cover 301. Multiple screws Ⅲ 302 are evenly arranged in the circumferential direction inside the protective cover 301. The bottom of the multiple screws Ⅲ 302 is fixedly installed on the corresponding connecting seat 203, thereby fixing the protective cover 301 on the upper side of the display board 202.

[0037] This section is based on Figure 1-16 The working process described is as follows: In order to ensure the integrity and stability of the overall mechanism, the protective cover 301 is fastened to the multiple connecting seats 203 on the display plate 202 by multiple screws Ⅲ 302, so that the protective cover 301 covers the outer circumference of the hinge closed-loop piezoelectric fast reflector 101, and the position of the refracted beam in the middle of the hinge closed-loop piezoelectric fast reflector 101 is located at the opening in the middle of the protective cover 301.

[0038] The outer shell 201 has a plurality of glue injection holes 204 evenly provided in the circumferential direction in the middle part.

[0039] This section is based on Figure 1-16The working process described is as follows: To maximize the buffering of lateral forces on the four piezoelectric ceramic components 401 inside the housing 201, thereby extending the service life of the piezoelectric ceramic components 401 while ensuring the normal usability of the overall structure, multiple injection holes 204 are uniformly machined along the circumference in the middle of the housing 201. A certain amount of aerospace adhesive is then injected into the housing 201 through these holes by production personnel. This aerospace adhesive encapsulates the multiple piezoelectric ceramic components 401 inside the housing 201. After a period of time, the adhesive elastically solidifies. When the four piezoelectric ceramic components 401 inside the housing 201 are subjected to lateral forces, the lateral force is transferred to the solidified adhesive encapsulating the piezoelectric ceramic components 401, thus maximizing the buffering of the forces on the piezoelectric ceramic components 401. This ensures the structural stability of the piezoelectric ceramic components 401 and improves their service life. The overall structure is stable, further enhancing reliability.

[0040] A fitting ring 501 is fixedly connected to the middle of the outer side of the outer shell 201. The fitting ring 501 has a plurality of corresponding holes that are evenly arranged along the circumferential direction and correspond one-to-one with the plurality of glue injection holes 204. A sliding ring 601 is fitted and slidably attached to the outer side of the fitting ring 501. A limiting rod 604 is fixedly connected to the left and right sides of the bottom of the sliding ring 601, and the two limiting rods 604 are slidably connected to the two sides of the fitting ring 501.

[0041] Multiple injection tubes 602 are uniformly fixed and connected along the circumferential direction on the sliding ring 601. The multiple injection tubes 602 are arranged in a one-to-one correspondence with the multiple corresponding holes on the fitting ring 501. The bottom of the multiple injection tubes 602 is uniformly fixed and connected along the circumferential direction to the upper side of the storage frame 603. A compression ring 701 is slidably connected inside the storage frame 603.

[0042] Each of the injection tubes 602 is a plastic telescopic tube.

[0043] A cover 605 is installed on the upper right side of the storage frame 603.

[0044] The bottom of the extrusion ring 701 is fixedly connected to a pusher plate 702.

[0045] This section is based on Figure 1-16The working process described is as follows: Multiple piezoelectric ceramic components 401 located inside the outer shell 201 are subjected to lateral forces for an extended period. After being squeezed and pushed by the solidified aerospace adhesive encapsulating them, deformation inevitably occurs at the contact points between the internal adhesive and the piezoelectric ceramic components 401. To facilitate timely replenishment of aerospace adhesive inside the outer shell 201 and ensure the piezoelectric ceramic components 401 maintain their stress-bearing function, during use, the cover 605 inserted into the heat-insulating storage frame 603 is first removed. Adhesive is then injected into the space formed by the cover 605 and the compression ring 701 for storage. In the initial state, the sliding ring 601 slides to the lower side of the bonding ring 501 by the two limiting rods 604. At this time, the corresponding holes on the bonding ring 501 do not affect the initial operation of passing through the corresponding holes. The corresponding injection hole 204 is used for injection. When additional glue is needed, the upward sliding ring 601 moves synchronously and the multiple injection tubes 602 expand and contract accordingly, so that the upper openings of the multiple injection tubes 602 correspond to the multiple corresponding holes on the bonding ring 501. Then, the user grasps the push plate 702 and pushes the extrusion ring 701 toward the storage frame 603. The extrusion ring 701 then squeezes the glue in the storage frame 603 and flows it into the corresponding injection tube 602. Then, the glue flows through the injection tube 602 and through the corresponding hole and injection hole 204 to inject the glue into the shell 201. This facilitates the timely replenishment of aerospace glue into the shell 201, so that the piezoelectric ceramic component 401 can continuously maintain its stress buffering function. The overall structure is simple and practical.

This causes the piezoelectric ceramic components 401 on both sides to push the bottom surface of the hinged closed-loop piezoelectric fast reflector 101, causing the surface of the hinged closed-loop piezoelectric fast reflector 101 to tilt at an angle, thereby adjusting the angle at which the light beam is refracted. The light beam is then refracted within the hinged closed-loop piezoelectric fast reflector 101.
