Among them, the air cushion material is selected from rubber rubber or plastic. The piezoelectric power generation module of the present invention may include a plurality of air cushions, which are spherical air cushions. And the lower cover of the piezoelectric power module has a recess for receiving the spherical air cushion and the electromechanical conversion unit. Further, the shape of the protrusion may be a cone, a column or a semi-circular sphere, wherein the protrusion is preferably a rigid material having a rigidity coefficient of about 0.7 or more. The piezoelectric power generation module of the present invention can also be a flat type, and the material of the upper cover and the lower cover is elastic and the rubber or plastic material of the peak can be flexed. Wind, bar pressure, 201220670 pressure or tap to output current. The flat type piezoelectric power generation unit of the present invention is selected to be connected to each other in series, _ fruit, and 'more including a plurality of electromechanical conversion types. One of the flat-type piezoelectric power generation modules, which is connected to the output end, is a rectifier, a rectifier motor. The flat piezoelectric output to the rectifying rectifier of the present invention is electrically connected to the charging device, and further includes a charging device to the charging device. '" Set, so that the rectified DC storage output can also be electrically connected. The replacement unit is subjected to external force to generate a load circuit to make the electromechanical supply current to the load circuit. After the electric circuit b is taken out to the rectifier, the advantages and disadvantages of the present invention can be obtained by the following invention. [Embodiment] It is understood that the following rhyme and advantages can be more obvious and compatible. For the __ module, the county record embodiment, the components will be the same with the same component = ',, and the following is the same as the following. The piezoelectric generating mold of the present invention compresses or stretches the electric power meter, 1 does not use the piezoelectric structure in the cantilever structure call generation module 3 = sends another new structure, so that the pressure =, right = see = = face Hair, example piezoelectric power generation molds - including the upper cover 10, a 1; cover = not intended. Piezoelectric power generation module cover 11, electric and mechanical conversion unit 12, - $ t 7 201220670 pad 13, and a plurality of protrusions 14. The piezoelectric power generation module 1 of the embodiment of the present invention is a flat piezoelectric power generation module, and the upper cover 10 and the lower cover 11 are made of an elastic material, and a rubber or plastic material that can be flexibly arbitrarily selected, such as silicone rubber, Polymers such as latex and polyurethane (PU) enable the flat-plate piezoelectric power module to output current by any deflection, bar pressure, rolling or tapping. The structure and principle will be detailed later. Said. Please refer to FIG. 2, which is a schematic diagram of the electromechanical conversion unit 12 of the present invention. The electromechanical conversion unit 12 includes a metal piece 120 to which a plurality of piezoelectric sheets 122 are attached on at least one side. The electromechanical conversion unit 12 is electrically coupled to an output end 123 for outputting electrical energy generated after the piezoelectric sheet 122 is deformed. In the embodiment of the present invention, in order to increase the output electric energy, a plurality of piezoelectric sheets 122 are attached to the lower surface of the metal piece 120. In addition, the electromechanical conversion unit 12 of the present invention utilizes a circuit board 124, as shown in FIG. 2, to connect the piezoelectric sheets 122 in series or in parallel, and output currents generated by the deformation of the piezoelectric sheets to Lose φ at the end 123. Another preferred embodiment of the present invention, as shown in Figures 3A through 3C, selectively uses a plurality of electronic components 125 to electrically connect the piezoelectric sheets 122, as shown in Figure 3A. The advantage of using the electronic component 125 is that the piezoelectric sheet has a large deformation space' and provides sensitivity to the piezoelectric conversion of the piezoelectric power generation module 1. In addition, since the piezoelectric sheet 122 is generally made of a ceramic material, if the area of the piezoelectric sheet 122 is too large, it is easily broken when subjected to a flexing force, particularly in the present case, in order to make a flat piezoelectric layer. The power module 1 can be as thin and light as possible, and at the same time, the piezoelectric sheet 122 can be protected from [S] 8 201220670, which may be broken due to excessive external stress. In the embodiment of the invention, the piezoelectric sheet 122 has an area of about 11 to 13 mm 2 . And between each other, a predetermined distance apart. Also, each of the piezoelectric sheets 122 has an aspect ratio of about 1 to 10 to facilitate bending of the piezoelectric sheets 122 to cause deformation. Since the piezoelectric power generation module 1 of the embodiment of the present invention is of a flat type, in order to force the electromechanical conversion unit 12, the piezoelectric sheet 122 can generate sufficient deformation in a limited space, and the present invention is in the piezoelectric state. An air cushion 13 is disposed under the sheet 122 to provide a space for the piezoelectric sheet 122 to be deformed. In addition to this, it is also possible to protect the piezoelectric sheet 122 made of a ceramic material so that it is not easily cracked due to excessive stress. In the present embodiment, a plurality of air cushions 13 are used, and the air cushion 13 is an air cushion ball. Of course, in order to adjust the spring constant, the bubble ratio inside the sphere can be controlled, or a hollow spherical shell can also be used. The shape of the air cushion 13 referred to herein is merely an embodiment for convenience of explanation, and it is not limited to the illustrated shape, and other shapes are also possible. A plurality of air cushions 13 are intended to generate a restoring force, and therefore, a resilient small spring luer is naturally one of the alternatives that can be selected. The lower cover 11 has a recess 110 in which a plurality of spherical air cushions 13 are laid, and the electromechanical conversion unit 12 is stacked on the air cushion 13. The material of the air cushion 13 is selected from the group consisting of rubber, silicone, foam, styrofoam or foamed plastic pellets. A plurality of protrusions 14 are provided on the inner surface 101 of the upper cover 10, and when the upper cover 10 is coupled to the lower cover 11, the electromechanical conversion unit 12 is located between the protrusions 14 and the air cushion 13. When the piezoelectric power generation module 1 receives an external force, the protrusions 14 can simultaneously make a plurality of piezoelectric [s] 9 201220670 pieces 122 on the electromechanical conversion unit 12, and increase the unit area of each force point. Force' enables these power-transfers 122 to simultaneously output electrical energy, effectively improving the piezoelectric conversion efficiency. The protrusion 14 of the embodiment of the present invention is a cone with a vertex facing downwards, that is, a lower tip, and of course, the tip is not too sharp. In the embodiment of the present invention, the tip of the cone has rounded corners or is set with small beads. Most preferably, the projections 14 are preferably made of a rigid material having a stiffness coefficient of greater than about 0.7. As shown in Fig. 1B and Fig. ,, the protrusion Μ is characterized by an upper surface area close to the upper end of the upper cover egg squeezing end) which is larger than the lower surface area of the contact point of the electromechanical conversion unit 12 to exert a pressure amplification effect. The larger the upper surface area/lower surface area ratio, the better the amplification effect. The projections 14 may be fixed to the inner surface 101 of the upper cover 10 in any conventionally fixed manner, or may be integrally formed with the upper cover 10. & In a preferred embodiment, the aforementioned protrusion 14 may also be a three-quarter sphere or a semi-spherical sphere in one embodiment of the invention, however, as long as the upper surface area is greater than the lower surface area of the force contact point, and It is not limited to the shape described in the embodiment of the present invention, and of course, when the projection 14 is a semi-spherical sphere, it has an optimum effect as shown in Fig. 4A. There is only one point of contact between each protrusion 14 and the piezoelectric piece 122. In addition to the effect of pressure amplification, since the shape is relatively round, the damage to the piezoelectric piece 122 is small when the upper cover is impacted by an external force. The service life of the piezoelectric power generation module of the present invention can be extended.

Other shapes and variations that can be easily inferred by those of ordinary skill are also included in the scope of the present invention [U 10 201220670, It is not described here one by one. On the other hand, the protrusions 14 are semi-spherical spheres, and the multi-layer electric power generation modules can be vertically stacked to improve the efficiency of piezoelectric conversion per unit area, as shown in Fig. 4B. As long as a pad 19 is added between the upper and lower sets of electromechanical conversion units 12a and 12b, the material is like the upper cover 10 or the lower cover 11, and the rubber or plastic material can be arbitrarily flexed, for example, silicone, latex, PU, etc. Molecular polymer. The lower surface of the backing plate 19 also has a plurality of semi-spherical spherical protrusions 14, in addition to providing a deformation space for the upper piezoelectric sheet 122a, and also applying pressure to the lower piezoelectric sheet 122b to provide a pressure amplification effect. The present invention has the advantage of using a plurality of protrusions 14 compared to a design using only a single protrusion, that is, for each stressed piezoelectric piece, the force-electric coupling relationship is still in the linearly varying region, so that the stress energy More efficient conversion to electrical energy output. Although the design of a single protrusion can increase the force per unit area, since the stress is concentrated on the same piezoelectric piece, the current output by the piezoelectric piece does not increase indefinitely as the amount of deformation increases. In the end, saturation will still be reached. At this time, even if the piezoelectric piece is continuously forced to deform, no more current can be supplied. Of course, according to the actual application requirements and the size of the input mechanical energy, the number of the electromechanical conversion unit 12 and the piezoelectric sheet 122 and the arrangement of the electromechanical conversion unit 11 can be arbitrarily changed, and one of series, parallel, and any combination thereof can be selected. The ways are connected to each other to increase the power generated by the conversion. In the embodiment of the present invention, in order to make the piezoelectric power generation module 1 can be applied to the outdoor environment or in some environments with heavy humidity, the pressure [s] 11 201220670 electric power generation module] is packaged with an electric module 鈒1 In order to prevent the water vapor film layer 15 from covering the dust power loss. A, causing the electromechanical conversion unit 12 to be subjected to the block diagram of FIG. 5 'the function of the piezoelectric module 1 is electrically connected to the device 16, and the electric energy generated by the second house ^ Reconnected to a charging device =: 16 whole ... 6 DC. The charging device 17 can 16 output a pool.疋电谷 or a charging electric wheel outlet 123 can also be an electric-light-emitting element, so that the electromechanical conversion /, the load circuit 18, such as after the wheel to the rectifier 16, 艮, _ ^ where the 12 fork external force generated by the power The invention (4) _ secretly the load circuit 18. The x-ray 1 module has the following advantages: (1) Using the air cushion to provide the deformation space of the piezoelectric piece of the anaerobic structure, compared with the conventional electric meter in the limited space = the invention of the piezoelectric power module can The body of the piezoelectric piezoelectric module is deformed and the current is outputted. The shell and the material are even prepared into a flat-shaped knot. (2) By using the multi-Hungarian protrusion force and amplifying the piezoelectric sheet 4, the effect of the plurality of piezoelectric sheets at the same time efficiency can be obtained. The pressure of the force is increased to improve the piezoelectric transformation. (3) The structural design has the vertical lamination force of the conversion unit, /, and the efficiency of the piezoelectric generating module can be increased by a plurality of units per unit area. 201220670 (4) It is widely used, regardless of the application method such as dust or enemy attack, it deflects _ and the key group outputs electric energy. When the piezoelectric generating mold of the present invention is used, for example, at both ends = when the structure is removed, the panel is enlarged after the panel is set to ^, and the flat piezoelectric cracker and the panel are bent by the wind to make the panel pressed. = electric hair package module sand, to be able to send electricity (four) group can also use the period 'also read Xiao Chunjin vehicle Lai Wei can change the large face' as the power used by pedestrians or vehicles to use = mechanical energy.卩 仃 车辆 车辆 车辆 对 对 对 对 对 对 对 对 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于Send the god and the sacred face to the above.
