Description of the invention: [Technical field to which the invention belongs] At present, the method of providing power specification conversion is through an electromagnetic transformer. However, such a conventional wound-type transformer has long been prone to overheating due to easy overheating. As a result of the safety problems in the use of various electrical products, this question has become a very difficult problem in the current situation that the technology products are required to be light, thin, short and small, and the electromagnetic transformer must be wound. The smallest size that can be reached has reached its limit, forcing industry and academics to actively look for alternative new power conversion components in recent years. Piezoelectric transformer (US Patent No. 2830274) proposed by C. A. Rosen in 1956. Figure 1 shows the basic design structure of a piezoelectric transformer. Due to its simple structure, it is easy to manufacture a thin size. The industry and the academic community have jointly identified the next generation of power supply modules. Piezoelectric transformers are the only important components that can replace the electromagnetic transformers. In addition to the great advantages in size, the efficiency can be higher than that of Na, far exceeding The conversion efficiency of the electromagnetic transformer _, the 纟 also has a very high energy density (causage density), can handle higher power conversion in the same size, and its extremely high reliability (reliability) When the cylinder is beyond the gg boundary, the health is only a fracture of the mechanical structure, and there is no danger of Weilu mosquito. The basic principle of the electric pressure and the electric energy conversion is the force rotation characteristic of the piezoelectric material, and the specification of the electric energy. Transforming, so it is not natural to generate electromagnetic waves, which is unmatched by traditional electromagnetic piezoelectric transformers, so piezoelectric transformer technology - a high conversion efficiency, High-energy unit, 1288588 South reliability, and low electromagnetic wave thin-shaped lightning six clocks to convert 70 power. At present, the industry of thin display is taking off. Among them, the liquid crystal display (the cold cathode lamp used in liquid crystai needs high voltage driving, and the thin structure, high efficiency, low electromagnetic wave piezoelectric surface is the best power specification. Conversion component.- Since the piezoelectric transformer utilizes the resonance characteristics of its own mechanical structure, the only place where the pressure can be erected is that the structure of the pressure is only a secret, and it cannot be placed in the high temperature after the completion of the manufacture. Loss, this feature makes the piezoelectric mass spectrometer's automatic mass production feasibility greatly reduced, and relatively increases its production cost. This case is aimed at this - mechanical structural characteristics, eliminating the traditional design concept of the knowing technology, and proposing a high hardness knife type The continuation mechanism directly erects the innovative erecting device and method on the circuit board, and proposes a knives-type clamping mechanism made of metal to reduce the noise of the pressure-relieving pressure and improve the life of the negative ship or component. Import and export of electrical energy, and achieve the role of heat dissipation' is an innovative piezoelectric transformer with system integration capability and green The clamping mechanism and method of the private riding revealing Lin can also be considered in the mechanical resonance of any piezoelectric element (4), which should also be the scope disclosed in the present disclosure. [Prior Art] Due to the piezoelectric transducer (Piez〇electric) The basic operating principle of the transducer is to apply the mechanical resonance characteristics of the piezoelectric ' _ its light-weight material properties to achieve the effect of power conversion. In other words, the piezoelectric transducer itself is a mechanical structure, so its erection can not be changed BQundary 1288588 conditions 'Off-hook mode will give the piezoelectric transducer an unnecessary boundary condition'. The resonance characteristics of the original design make the overall system efficiency of the pressure damper And the life is reduced, and even lead to complete failure, so the correct loss: the structure will be an important product index of whether the piezoelectric transducer can achieve its best working efficiency. Because the working point of the piezoelectric transducer is set in a certain a selected mechanical resonance frequency (resonance freq job cy), so the only node that does not change with the resonance waveform is the node of the selected mechanical resonance frequency (nGdal pQint), due to the node Positive and small, its clamping mechanism _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ , so the only place that can be wired is the node and its free-end, g is only the two places are not affected by the structural resonance', and the loose drag is dropped. In contrast, if the wiring is fixed to other Place, it will be easy to make the piezoelectric hard H turn to produce high heat, and the electric effect of the ecstasy will disappear. Piez〇electric transf〇rmer is the most representative product of the piezoelectric transducer, A number of erection techniques have been developed. Traditionally known techniques have been installed on the circuit board. The first type can be divided into two types. The first one is to use a - external box to convert the piezoelectric (4) Set in the external box, and then install the external box on the circuit board. [There is a mass-produced component as a whole, but the relative materials and "costs are relatively improved." Traditionally, the ray-receiving type can be divided into two types. The first type uses a structure of elastic 1288588 to hold the piezoelectric transformer (US Patent No. 6〇54798, 〇57633, 5747916), using the elastic structure itself. Elasticity, as shown in Figure 2 (&), the elastic piece 2 clamps the piezoelectric transformer 22 (four) point to the piezoelectric transformer (four) erection, the structure can be a conductor or a non-conductor, the towel has a conventional technology Lifting the elastic structure with conductive characteristics to introduce or extract electric power into the piezoelectric transformer to reduce the cost of the artificial tan wire. The biggest disadvantage of erecting the piezoelectric transformer with an elastic structure is that a complicated functional external box 23 must be designed. The elastic structure is fixed on the upper part, and then the piezoelectric transformer is installed in the external box. Moreover, since the elastic clamping mechanism cannot ensure that the clamped position is maintained at the node of the structure, it must be fixed to the node by means of glue. Upper, but this will make the contact area must be larger, and the adhesive of the glue is easy to limit = the piezoelectric dragon is moving, the high heat is also generated, and the maximum wattage that can be operated with the sacrificial pressure device is eliminated. outer, This method can successfully push the piezoelectric transformer into the mass production process's. However, due to the extra design of the external box mechanism, the elastic clamping mechanism, and the fixing agent, the material cost is greatly increased, but the market is reduced. Competitiveness. In addition, a conventional technique is a soft adhesive, and the electrostatic device is fixed on an external casing (US Patent No. 795, 62働13), and the electrostatic ink-changer 22 of FIG. 2(6) is composed of two soft ones. Adhesively, it is fixed on the external box 25, the basic design concept is to use the soft adhesive to directly bond the electric device to the external box, the effect of the electric ray, the secret adhesive, wish The electric transducer is less susceptible to the damping effect caused by the vibration during the vibration, so the position of the adhesive 1288588 does not need to be quite accurate, and can cover a large area, thereby improving the feasibility of mass production. The need to reduce the external box mechanism does not require the design of a precise flexible money mechanism, which greatly reduces the production cost, but the reliability of the product is relatively reduced. 'This is because the soft erection method is not really complete:' After the piezoelectric transformer is long, the high temperature generated by the vibrating county will accumulate. Here, the soft adhesion _ 'prone to high temperature will also cause the piezoelectric material to drift or disappear due to _, and then make the pressure Electric surface The drive circuit fails, causing the overall power supply (4) to fail. The same as the soft adhesive itself will soften due to heat, which makes the pressure of the pressure and the financial doubts. Therefore, the tile that can be operated by the piezoelectric transformer 11 of this erection mode can be operated. The number is usually quite low to ensure that its temperature rise is not too high, and this limit reduces the range in which the M variator can be applied. • Although the second transmission, 'the first provincial technology successfully used the piezoelectric transformer installed in the external box to convert into a mass-produced component, and the external box provides a protective function of the piezoelectric transformer, so that the vibration handle is interfered by the outside, However, due to the design of its complex recording mechanism, its entire area is increased, but it is impossible to observe the advantages of _ _ _, and the size and geometry of the pure circuit due to piezoelectric transformers are different. It is necessary to design different external boxes for different piezoelectric transformers, and the elastic clamping mechanism 'or change the soft material coating health, which becomes an inevitable production cost, and also reduces the market of the electric transformer. SUMMARY OF THE INVENTION Since the piezoelectric transducer operates on a coplanar surface of a selected structure, only the node of the selected structural resonance is not _ place, so the node is the clamping pressure 11 1288588 electric transducer only - The position of the screen of the present invention is to add a method of adding an electric transducer to the elastic or soft interface material, and proposes a high-hardness knife-type clamping mechanism to directly clamp the piezoelectric device at a mechanical force. On, and the knife holding mechanism can be directly fixed on the circuit board, is - interface (four) Wei device becomes mass production - a basic reading, its main design concept is shown in Figure 3, high hardness knife type clamping mechanism% folder Holding the work on the 33_ electric conversion of the vibration state, due to this innovative direct clamping method, the piezoelectric transducer is directly clamped by mechanical force, so no need to use extra _ It is fixed, so it will not accumulate high temperature when it is used, but there are factors such as falling and (4) unreliable factors such as drifting and disappearing of characteristics, because the invention of the knife-type Zhao mechanism is mechanical Force to hold on the working mode node, will not The rubbing causes high temperature build-up and a clamping mechanism that does not consume the mechanical energy and efficiency of the piezoelectric transducer. Since the piezoelectric transducer is inherently a mechanical structure, it has a plurality of wireless resonant modes, % 'so if the input power signal of the piezoelectric transducer is not a single frequency signal, the resonance of other frequencies will be due to itself. The piezoelectric effect produces resonance, in addition to the energy loss caused by the Xin, it will also shorten the load and life of the load circuit. For example, the cold cathode tube driven by the piezoelectric transformer is the most representative load circuit for its towel, so Traditionally, the driving circuit of the piezoelectric transducer has to eliminate this harmonic effect. It is necessary to increase the design and components of many circuits to reduce this effect, and cannot reduce the cost and overall power system. size. Because the innovative knife-type clamping mechanism in this case is mechanically clamped on the call point of the selected work 12 1288588 resonance frequency, 'naturally provides a mechanical binding force, and mechanically suppresses the vibration of other structural resonance modes. The use of mechanical forces to create new boundary conditions, such as a band-pass (1) shirt, reduces the resonance characteristics of other modes, and does not affect the structural characteristics of the original working resonant mode. 4 is - experimental data actually implemented, the second resonant frequency 41 is the selected working resonant mode 'The frequency response of the piezoelectric transducer is gray curve 43 without clamping. When the knife-type clamping mechanism of the present invention is clamped, the frequency response function becomes a black curve 44, and the actual data shows that the gain of the adjacent non-working mode is reduced by 15. 5 cents. The selected working resonance frequency is completely unaffected, so the knife-type holding surface invented in the present invention has a mechanism for reducing the harmonic characteristics of the structural system, and can greatly reduce the driving circuit thereof. Complexity and amount of components, and reduce the size and cost of the overall system. The invention also proposes to manufacture the material of the conductive ship, and the knife-type disaster-retaining mechanism invented by the present invention directly sends the piezoelectric transducer to the piezoelectric transducer by the clamping mechanism, because the knife-shaped jig designed in the present case is The high-hardness material can be directly mounted on the circuit board, completely eliminating the cost of materials that need to be electrically conductive by an additional mechanism, or the labor cost of artificially welding the wire, and reflecting the innovative knife-shaped coolness of the case. Mass production capacity. 'In addition to not consuming the mechanical energy of structural resonance, the knife-type jig of the present invention can also adopt a material having thermal conductivity, such as a metal material, to derive the thermal energy generated by the piezoelectric transducer due to high-speed vibration from the piezoelectric body. The function of achieving heat dissipation provides an unreliable function of preventing the piezoelectric transducer 13 1288588 from drifting due to temperature rise. - 2 The contact surface of the tongs and the Wei (4) in this case is approximately 丨..., when the surface of the galvanic transducer electrode of the read contact is extremely high, the instrument with a power reading tool will When the power is led or the thief is removed, the value of the thief will be reduced, that is, the resistance will become larger. 'To ensure the power transmission of the knife-type fixture and the _ transducer electrode, the case is also mentioned (4) - the secret conduction town or the welding center The electro-transducer electrode is indeed engaged, and the _ electric transducer has been clamped by the knife-type jig, so the conductive viscous crucible does not need a considerable area as in the conventional technology to ensure its Unaffected by structural vibrations, and tightly bonded to the electrodes of the (4) transducers - so - the method of bonding the knives and electrodes with the hybrid conductive scaly tin proposed by the ride will not be as large as the traditional The way the area is joined can be plagued by falling due to softening or falling due to rising. Therefore, the knife-type jig that is innovatively invented in this case is that it has the function of reducing noise and improving the life of the load circuit, reducing the number of system components, conducting and dissipating heat, and having mass-produced components directly mounted on the printed circuit board. Providing innovative devices and methods for piezoelectric transducer crying to mass production and automated production, any of the fine-grained clamping methods of the proposed method is set up in the case of - selected structural resonance mechanical structure, which should be applied for in this case. The scope of the patent. [Embodiment] The piezoelectric transformer transformer used in the piezoelectric transducer is one of the most representative ones. The following is the best example of the R-fiber piezoelectric transformer, to uncover the innovation proposed by the present invention. Knife type clamping mechanism. μ 1288588 Checking the electric transformer n is a structural electric resonance device with a structural resonance. The wattage that can be transmitted and the best work efficiency that can be achieved are the most important demands, so it is positive for the piezoelectric transformer. The clamping device is very important. Even if the design of the piezoelectric transducer power supply system is more precise and accurate, the wrong way of setting up will not be able to reach the original design, and the scale of the electrical and mechanical properties caused by the drift of the electrical characteristics. Parameter changes, /, vibration frequency movement, boost ratio and low efficiency, that is, temperature rise problems that cannot be ignored, may even cause the possibility of overall system failure or damage. The boundary condition of the piezoelectric transformer belongs to the free end, so there is no practical place to use the actual temple. Therefore, the node generated by the resonance of the piezoelectric transformer is the clamping zone. The position of the node does not follow the structure. Resonance changes and moves, that is, in the form of waves, it is easy to say that the piezoelectric transformer converts the mechanical energy of its electrical energy into standing waves between nodes and nodes. At present, there are a large number of patents that aim to design a new clamping method, and try to mount the piezoelectric transformer on the circuit board without causing the structural resonance to be affected.

It can be seen from the figure that it is a three-node device, 11 is the input terminal, 12 is the output terminal, and the grounding is %13. The modality is a full-wave resonant mode modality as shown in Fig. 3. 15 1288588 It is known from the figure that the resonant mode has two nodes 34, and Fig. 5 is a piezoelectric clamp clamped by the present invention. A schematic diagram of the transformer, which allows the knife-type clamp 54 designed in the present case to be directly fixed on the printed circuit board 51. The piezoelectric transformer 55 can be directly clamped by a single-sided knife-shaped button 54 on the circuit board, and can be used. The fixture with conductive characteristics is directly soldered to the printed circuit 53 on the circuit board 51, and the voltage regulator drive circuit 52. Therefore, the entire system is compatible with the printed circuit technology, and is an innovative design for mass production capability. In addition, it is straightforward to note that since the knife-type jig proposed in this case is made of a high-hardness material, it has the ability to mount an electric transformer in its own life, so the circuit board 51 can be dug-like. The groove, the electric charge is held in the groove to reduce the overall size, successfully breaks through the traditional conventional technology needs - after the extra external box wire is fixed, it is turned on the circuit board Hey, can't bother with the overall size. Figure 6 is a schematic view of a second preferred embodiment of the present invention, the circuit rhyme having a rectangular recess 62' concavely mounted with two bilateral Yao knife-shaped jigs 63 disclosed in the present case. The recess is shown and supported by the grip. The fixture 63 is designed to touch the nodes of the singularity of the singularity of the singularity. Therefore, in addition to the swelling pressure, the swell can suppress other non-working modal vibrations. It is also possible to directly solder the printed circuit 64 on the circuit board 61 with a conductive member having a conductive property to achieve the function of transmitting power. 7 is a schematic view of a second preferred embodiment of the present invention. A circuit board 7 has a 16 1288588-rectangular recess 72 thereon. The rectangular recess 72 has two vertical knife-type clamps 73. The piezoelectric transformer 55 can be illustrated. The towel is shown in the groove, and is supported by the secret 73. Since this has always been a vertical knife, it is easy to install with the pressure of H, which reflects the innovative erection of the job in this case. Similarly, a fixture having conductive characteristics can be used to directly align the printed circuit 64 on the circuit board 61. The power of the power transfer b 0 is shown by the piezoelectric change shown in FIG. 1 (4). A variety of different functional electrodes, so the fixture with conductive characteristics must be designed according to the needs, Figure 8 (a) is an example of the input end and ground of the R0Sen type piezoelectric transformer of Figure 1, The piezoelectric transformer is not actually drawn in the figure. The knife-type clamp with conductive properties is divided into upper and lower parts. The upper clamp 81 and the lower clamp 82 are respectively welded or directly mounted on the circuit board, because of their own conductive properties. The electrodes on the printed circuit board can be directly soldered, and the upper and lower electrodes of the piezoelectric transformer to be contacted are individually connected to the drive circuit via the upper and lower clamps via the printed circuit 83, 84, and FIG. 8(b) is a cross-sectional view thereof. FIG. 9 is a view of another preferred embodiment. The upper and lower clamps having no conductive property and 92 are plated with a conductive layer 93, and the upper and lower electrodes of the contacted piezoelectric transformer are individually passed through the upper and lower conductive layers 93 via the printed circuit. 83 is 84 connected to its drive circuit. Figure 10 is a side elevational view of a preferred embodiment of a Rosen-type piezoelectric transformer in which the conductive upper and lower clamps 81 and 82 sandwich the node of the piezoelectric transformer driver, and the conductive upper clamp 81 drives the circuit The outputted electrical energy is fed into the input terminal of the piezoelectric transformer 17 1288588, and the conductive lower clamp 82 connects the grounding end of the piezoelectric transformer with the ground of the driving circuit, and further has a knife having no conductive characteristics. The type clamp clamps the node of the piezoelectric transformer H output end, and completes the erection of the pressure and pressure, and the output power and the 12-very short wire are soldered on the circuit board 92. In the load circuit. Figure 11 is a soft conductive adhesive or solder ill proposed in the present case, and the blade clamps 81 and 82 and the piezoelectrically-transferred electrode 丨丨 are connected to each other. 55 is indeed clamped, so the soft conductive adhesive or fresh tin 111 does not require a large area, only (4) can be connected, it is worth mentioning that the soft conductive or solder 111 can be coated on the side-point, or The township point is applied to the edge of the contact line. The material of the knives invented in this case can be designed according to the nature of the piezoelectric embossing node of the scale. If the node to be clamped is the electrode, the material with the ability to conduct heat conduction immediately can be used to give the signal. Or take it out, and the heat generated by the vibration is poured out. In addition, if there is no electrode in the clamped_node, the heat-conducting wire is not clamped, and the heat generated by the vibration is guided to $ Optimized design of the system. Since the innovative knife-type jig proposed in this case is designed for the node of any structure, it is not limited to the narrow structure disclosed in the present case, as long as it is clamped at any node of the structure resonance in a knife-type manner. The scope disclosed in this case. [Simple description of the diagram] 18 1288588 Figure 1. Schematic diagram of a Rosen-type piezoelectric transformer.
