Description

Technical Field

[0001] This utility model relates to the field of SIPM oscillating plate technology, specifically an improved SIPM oscillating plate. Background Technology

[0002] In existing SIPM (Smart Piezoelectric Array) technology, the array plate typically uses a uniformly distributed array of piezoelectric oscillators and a linear waveguide channel. However, in practical applications, the following problems exist:

[0003] 1. Uneven distribution of vibration energy: Due to the fixed spacing of the piezoelectric oscillators, the vibration attenuation in the edge area is severe, resulting in a decrease in the overall excitation efficiency and uneven distribution of vibration energy. Furthermore, under the interference of standing waves, the straight groove structure is prone to forming standing waves, and the vibration energy in some frequency bands cannot be effectively transmitted.

[0004] 2. The existing waveguide channel design with a single-depth trench cannot adapt to vibration waves of different frequencies. High-frequency signals are severely reflected at the edges, and due to the lack of branching structure, energy is only transmitted along the main trench, resulting in delay in the excitation of the secondary oscillator and phase distortion.

[0005] 3. Existing interface modules, due to their use of fixed matching circuits, cannot adapt to multi-band drive signals, resulting in limited bandwidth. Furthermore, traditional star wiring causes a drop in the excitation voltage of the far-end oscillator, leading to uneven signal distribution.

[0006] 4. Defects in protection and heat dissipation: The use of a closed enclosure affects heat dissipation and has a shielding effect on high-frequency vibration waves. Residual vibrations are reflected inside the enclosure, increasing noise. Utility Model Content

[0007] In view of the above, this utility model provides an improved SIPM resonator plate to solve the problems mentioned in the background art.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: an improved SIPM resonant plate is provided, including a substrate unit, a vibration transmission layer, and an interface module. The substrate unit is composed of a rigid support frame and an elastic matrix layer. The rigid support frame is provided with staggered reinforcing ribs, and the elastic matrix layer is filled in the grid cavity formed by the reinforcing ribs. The vibration transmission layer includes piezoelectric vibrators arranged in a matrix and waveguide channels. Each piezoelectric vibrator is fixed to the node position of the rigid support frame by an embedded mounting base. The waveguide channel is composed of radial grooves and connects adjacent piezoelectric vibrators. The interface module integrates a signal distributor and an impedance matching circuit. The signal distributor connects each piezoelectric vibrator through layered wiring, and the impedance matching circuit is provided with an adjustable inductor component and coupled to an external driving device. The reinforcing ribs of the rigid support frame form a dense mesh structure in the four corner areas, and the groove depth of the waveguide channel changes in a stepped manner from the center to the edge.

[0009] Preferably, the embedded mounting base includes a tapered groove and a buffer flange. The inner wall of the tapered groove is provided with anti-dislodgement teeth, and the buffer flange adopts a wavy profile and forms surface contact with the rigid load-bearing frame.

[0010] Preferably, the radial grooves of the waveguide channel include a main groove and a secondary groove. The main groove extends along the direction of the piezoelectric vibrator connection and has a trapezoidal cross-section. The secondary grooves branch and connect to the main groove at an angle of 30-60 degrees.

[0011] Preferably, the adjustable inductor assembly includes a rotating magnetic core and multi-stage windings. The rotating magnetic core is connected to an adjustment knob via an axial positioning pin, and the multi-stage windings are wound in a layered, interleaved manner.

[0012] Preferably, it also includes a protective cover, which is composed of a wave-transparent top plate and a metal frame. The inner surface of the wave-transparent top plate is provided with a wave-absorbing coating, and the metal frame is detachably connected to the substrate unit by elastic buckles.

[0013] This improved SIPM vibration plate solves the edge vibration attenuation problem caused by traditional uniform distribution by setting a reinforcing rib grid structure. The designed stepped groove depth overcomes the uneven energy distribution caused by the standing wave effect. At the same time, the adjustable inductor component improves the bandwidth limitation caused by traditional fixed impedance, and the combination structure of tapered slot and buffer flange eliminates the risk of oscillator falling off. Therefore, through the composite substrate structure, graded waveguide channels and dynamic impedance matching, it solves the three core problems of traditional vibration plates: large energy loss, narrow bandwidth and low reliability. It is especially suitable for high-frequency precision vibration control scenarios. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0019] exist Figure 1-3 The present invention provides an improved SIPM resonant plate, comprising a substrate unit 1, a vibration transmission layer 2, and an interface module 3. The substrate unit 1 is composed of a rigid bearing frame 4 and an elastic matrix layer 5. The rigid bearing frame 4 is provided with staggered reinforcing ribs 6, and the elastic matrix layer 5 is filled in the grid cavity formed by the reinforcing ribs 6. The problem of edge vibration attenuation caused by the traditional uniform distribution is solved by setting the grid structure of the reinforcing ribs 6.

[0020] In this embodiment, the vibration transmission layer 2 includes piezoelectric vibrators 7 arranged in a matrix and waveguide channels 8. Each piezoelectric vibrator 7 is fixed to the node position of the rigid bearing frame 4 by an embedded mounting base 9. The waveguide channel 8 is composed of radial grooves and connects adjacent piezoelectric vibrators 7. The radial grooves of the waveguide channel 8 include a main groove 15 and a secondary groove 16. The main groove 15 extends along the direction of the connection of the piezoelectric vibrators 7 and has a trapezoidal cross section. The secondary groove 16 branches and connects to the main groove 15 at an angle of 30-60 degrees. The designed stepped groove depth overcomes the uneven energy distribution caused by the standing wave effect. At the same time, the adjustable inductor component improves the bandwidth limitation defect caused by the traditional fixed impedance.

[0021] In this embodiment, the interface module 3 integrates a signal distributor 10 and an impedance matching circuit 11. The signal distributor 10 connects each piezoelectric vibrator 7 through layered wiring 12. The impedance matching circuit 11 is equipped with an adjustable inductor assembly 17 and is coupled to an external driving device. The adjustable inductor assembly 17 includes a rotating magnetic core 18 and multi-stage windings 19. The rotating magnetic core 18 is connected to an adjustment knob through an axial positioning pin 20. The multi-stage windings 19 are wound in a layered, interleaved manner. After the driving signal is tuned by the impedance matching circuit 11 of the interface module 3, it is distributed to each piezoelectric vibrator 7 by the signal distributor 10. The generated vibration is propagated directionally through the groove network of the waveguide channel 8. The reinforcing ribs 6 of the rigid bearing frame 4 provide support and limit the lateral vibration diffusion. The elastic matrix layer 5 absorbs residual vibration.

[0023] In this embodiment, a protective cover 21 is also included, which is composed of a wave-transparent top plate 22 and a metal frame 23. The inner surface of the wave-transparent top plate 22 is provided with a wave-absorbing coating. The metal frame 23 is detachably connected to the substrate unit 1 by an elastic buckle 24. The wave-absorbing coating can absorb vibration waves, reduce the reflection frequency of residual vibration in the cover, reduce noise, and is easy to install and disassemble by the elastic buckle 24.

[0024] In specific implementation, the driving signal is tuned by the impedance matching circuit 11 of the interface module 3 and then distributed to each piezoelectric vibrator 7 by the signal distributor 10. The generated vibration is propagated directionally through the groove network of the waveguide channel 8. The reinforcing ribs 6 of the rigid bearing frame 4 provide support and limit the lateral vibration diffusion. The elastic matrix layer 5 absorbs residual vibration. Through the composite substrate structure, the hierarchical waveguide channel 8 and dynamic impedance matching, the three core problems of high energy loss, narrow bandwidth and low reliability of traditional vibration plates are solved. It is especially suitable for high-frequency precision vibration control scenarios.
