Description

Technical Field

[0001] This utility model relates to the field of active actuator technology, and in particular to a novel active actuator. Background Technology

[0002] As a key actuator in active vibration control systems, actuators convert external energy into control force by receiving controller commands to suppress or eliminate structural vibration. Their applications cover multiple engineering fields, including building seismic resistance, shipboard vibration isolation, and automotive suspension adjustment, with active actuators being one such example. However, existing active actuators, when used with piezoelectric stacked structures connected in series with voice coil motors, typically employ threaded installation for limiting the connection and cannot quickly connect the two in series. This makes disassembly cumbersome during maintenance, reducing the effectiveness of the equipment. Furthermore, the need for a threaded installation process hinders quick installation and reduces the overall installation efficiency. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] See Figures 1-2 A novel active actuator includes an active actuator body 1, a series assembly 2, and a limiting assembly 3. The series assembly 2 is installed inside the active actuator body 1, and the limiting assembly 3 is installed on the active actuator body 1. A piezoelectric series connector 4 is installed on the series connector 2013, and a silent motor 5 is installed on one side of the piezoelectric series connector 4. The piezoelectric series connector 4 and the moving part of the silent motor 5 form a dynamic vibration absorption unit, which uses the anti-resonance frequency to suppress the specific frequency band vibration generated by the inertial force inside the system. Handles 6 are symmetrically fixed to the outside of the active actuator body 1. The active actuator body 1 is first placed in the designated position through the handles 6, which improves the transportation effect of the equipment.

[0020] The series assembly 2 includes a wedge-shaped extrusion plate 201, a servo motor 202, a lead screw 203, a first guide rod 204, a lifting plate 205, a threaded hole 206, a lifting hole 207, a second guide rod 208, a connecting plate 209, a first spring 2010, a series contact 2011, a guide hole 2012, and a series connector 2013. The servo motor 202 is embedded in the inner wall of the bottom end of the main actuator body 1. The lead screw 203 is fixedly connected to the top of the output shaft of the servo motor 202. A lifting plate 205 is installed at the top of the main body 1. A threaded hole 206 is opened in the middle of the lifting plate 205 corresponding to the position of the lead screw 203. A first guide rod 204 is symmetrically fixed to the inner wall of the bottom end of the main actuator body 1. A lifting hole 207 is symmetrically opened on the lifting plate 205 corresponding to the position of the first guide rod 204. Series contacts 2011 are distributed and installed on the outer side of the lifting plate 205. Second guide rods 208 are distributed and fixed on the outer walls of both sides of the lifting plate 205. The series contacts 2011 are corresponding to the second guide rods. A guide hole 2012 is provided at position 208. A connecting plate 209 is fixed to the outer wall of one end of the second guide rod 208. A first spring 2010 is fixed to the outer wall of one side of the connecting plate 209, and the other end of the first spring 2010 is fixed to the outer wall of the series contact 2011. A series connector 2013 is installed inside the series contact 2011. Wedge-shaped extrusion plates 201 are fixed to the bottom end of the active actuator body 1, and one side of the wedge-shaped extrusion plate 201 is attached to the outer wall of the series contact 2011. On the wall, the wedge-shaped pressing plate 201 presses the series contact 2011, causing the guide hole 2012 on the series contact 2011 to move along the second guide rod 208; the first spring 2010 is sleeved on the outer wall of the second guide rod 208, and there are four first springs 2010. When the series contact 2011 moves upward along the wedge-shaped pressing plate 201, the series contact 2011 is separated from the series connector 2013 under the action of the first springs 2010.

[0021] Working principle: First, the main actuator body 1 is placed in the designated position using the handle 6. Then, the series connector 2013 on the piezoelectric series connector 4 and the silent motor 5 is placed between the series contacts 2011. At this time, the servo motor 202 is started to rotate the lead screw 203. Then, under the action of the threaded hole 206, the lifting hole 207 on the lifting plate 205 is lowered along the first guide rod 204. Then, the wedge-shaped pressing plate 201 presses the series contacts 2011, causing the guide hole 2012 on the series contacts 2011 to move along the second guide rod 208. The series contacts 2011 are used to connect the piezoelectric series connector 4 and the series connector 2013 on the silent motor 5. When the main actuator body 1 is needed, the piezoelectric series connector 4 and the moving part of the silent motor 5 form a dynamic vibration absorption unit. The anti-resonance frequency is used to suppress specific frequency band vibrations generated by the inertial force inside the system. At the same time, it can also act as an active controller. When the main body 1 of the active actuator has a problem, the servo motor 202 is started to reverse the lead screw 203. Then, under the action of the threaded hole 206, the lifting hole 207 on the lifting plate 205 rises along the first guide rod 204, and the series contact 2011 moves upward along the wedge-shaped extrusion plate 201. Then, under the action of the first spring 2010, the series contact 2011 is separated from the series connector 2013, thereby disassembling the piezoelectric series device 4 and the silent motor 5. When the voice coil motor is connected in series in the piezoelectric stack structure, the structure can be limited and installed, and the two can be quickly connected in series. When maintenance is required, the disassembly process can be simplified and the use effect of the equipment can be improved.

[0022] Example 2

[0023] See Figures 1-2 The limiting component 3 includes a slide groove 301, a guide opening 302, a limiting insert plate 303, a vertical plate 304, a second spring 305, a rotating shaft 306, and an adjusting plate 307. The bottom end of the main actuator body 1 is provided with a slide groove 301. The limiting insert plate 303 is slidably connected in the slide groove 301. A guide opening 302 is provided on one side of the inner wall of the slide groove 301 corresponding to the position of the limiting insert plate 303. The top outer wall of the limiting insert plate 303 is fixedly connected to the vertical plate 304. The second spring 305 is fixedly connected to one side of the outer wall of the vertical plate 304, and the other end of the second spring 305 is fixedly connected to the inner wall of the main actuator body 1. The rotating shafts 306 are distributed and fixedly connected on the vertical plate 304 and the lifting plate 205. The adjusting plate 307 is rotatably connected on the outer wall between the rotating shafts 306.

[0024] When the main actuator body 1 needs to be installed, the servo motor 202 is started to rotate the lead screw 203. Then, under the action of the threaded hole 206, the lifting hole 207 on the lifting plate 205 descends along the first guide rod 204. The rotating shaft 306 drives the adjusting plate 307 to deflect downward, thereby sliding the limiting insert 303 on the vertical plate 304 along the guide opening 302 on the slide groove 301. The limiting insert 303 is then inserted into the designated position, thereby fixing the position of the main actuator body 1. When the main actuator body 1... When disassembly is required, the servo motor 202 is started to reverse the lead screw 203. Then, under the action of the threaded hole 206, the lifting hole 207 on the lifting plate 205 rises along the first guide rod 204. Then, the adjusting plate 307 is driven to deflect upward through the rotating shaft 306. Then, with the assistance of the second spring 305, the limiting insert plate 303 on the vertical plate 304 is reset along the guide port 302 on the slide groove 301. This allows for quick installation of the equipment itself without the need for a threaded structure, thus simplifying the installation process and improving the installation effect.
