In addition, the battery of consumer products, No: Pay attention to the size and service life of the battery, and at the same time, as the environmental awareness is raised, the battery is required to be green and environmentally friendly. Therefore, the battery has improved power storage and charging capacity, or a nitrogen-nitrogen battery that can be reused many times. Various designs, such as clock-ion batteries and solar cells, focus on the concept of green environmental protection. In particular, 'the company has developed a self-generating technology with a green concept, which can be used in various products to extend the power of the battery. In recent years, technology has gradually entered the mass market, such as hand-operated flashlights that do not require batteries. At the same time, the development of electronic products such as wireless networks and mobile communications has accelerated the development of such self-generating technologies. Whether the power generation capacity can meet the energy consumption requirements of electronic equipment is the biggest key point of this technology. Therefore, how to achieve the maximum power generation under the existing size structure is the biggest goal of this technology. Today's common self-generating technology can be mainly divided into two types, one is electromagnetic induction power generation technology 110494 5 1345845 l * • surgery, For example, U.S. Patent Nos. 4,7,9,9,176, 6,798, the entire disclosure of which is incorporated herein by reference in its entirety, the disclosure of which is incorporated herein by reference. No. 6, 768, No. 6, 768, 214, No. 7, 005, 779, etc. As shown in Fig. 3, U.S. Patent No. 6,812,583 discloses an electromagnetic induction type power generating device 3, which is electromagnetically induced. The power generating device 3 includes a hollow cavity 30, a movable magnetic body 32 disposed in the hollow cavity 3〇 and freely movable, and a magnetic body 3 fixed at opposite ends of the hollow cavity 3〇. a magnetic body 33 and an induction coil 34' wound around the hollow body 3〇, wherein the magnetic body 3 at both ends and the magnetic body 33 are disposed at the same polarity as the movable magnetic body 32 disposed at the center. Therefore, when the electro-magnetic induction power generating device 3 receives an external force When the movable magnet 32 is vibrated, the magnetic body 31 and the magnetic body 33 at both ends of the hollow body 30 are repelled by the same polarity, so that the movable magnet is reciprocated in the hollow body 30 while moving. In the process, the magnetic luer force line of the induction coil is cut to generate electric energy by changing the magnetic flux of the induction coil. However, in the design of the electromagnetic induction power generation device 3, the reciprocating motion of the movable magnetic body 32 is subjected to an external force and a magnetic body 31. In the design of the electromagnetic induction type power generation device 3, the volume of the magnetic body 31 and the magnetic body 33 must be increased in accordance with the predetermined power demand, thereby causing the electromagnetic induction type power generation. The overall volume of device 3 is difficult to scale down to actual product applications. As shown in FIG. 4, U.S. Patent No. 7,5,779 discloses a piezoelectric power generating device 4 comprising: a stack of 6 110494 I · 1345845 piezoelectric layers 40, a A pulley driving member 42' composed of a pulley 420 and a pulley follower 422 and an elastic member 44 disposed between the stacked piezoelectric layer 4A and the pulley driving member 42 when the pulley driving member 42 is actuated The elastic piezoelectric element 44 is applied to the stacked piezoelectric layer 4 〇 to compress and deform the stacked piezoelectric layer 40 to convert mechanical energy into electrical energy. In the above-mentioned piezoelectric material power generating device 4, since the stacked piezoelectric layer 4 is twisted and twisted to generate electric energy, the deformation is greater as the force is applied, and the electric energy generated by the month b is correspondingly increased. However, the electric energy generated by the stacked piezoelectric layer 4 is a small amount, and is driven by the driving member of the pulley 42 and receives an external force via the elastic member 44_, and is squeezed or impacted by an external force. Drive member 42 Once, the stacked piezoelectric layer 4〇 can only produce human-shaped edges, and only a small amount of electric energy can be generated in a single time, so the power generation frequency is = low frequency ', and the power generation efficiency is low' compared with the electromagnetic induction power generation technology. Words, the inability to operate at high frequencies is the most difficult reason for its implementation in actual product applications. Therefore, it has been a problem to solve the problem of how to develop a power generating device that solves various disadvantages of the above-described conventional techniques, thereby simplifying the structure, reducing the volume, and improving the power generation efficiency. SUMMARY OF THE INVENTION 4α is a disadvantage of the prior art described above, and an object of the present invention is to provide a power generating device capable of improving power generation efficiency. Another purpose of the moon is to provide a power generation device that can simplify the structure and reduce the volume. 110494 7

In this embodiment, the cantilever is a resilient piece and has a fixed end 11〇 and a free end 112 opposite the fixed end. The free end 112 is swingable relative to the base 1 by a certain amplitude. In addition, in this embodiment, the piezoelectric layer 13 is a piezoelectric film attached to the cantilever 11 , which may be one of one or more stacked layers, but not limited thereto, the piezoelectric layer 13 may also be, for example, a piezoelectric sheet fixed to the surface of the free end 112 of the cantilever 11 or the piezoelectric layer 13 may be a plurality of piezoelectric sheets including a plurality of piezoelectric sheets fixed to the surface of the free end 112 of the cantilever u and stacked on each other. The piezoelectric sheet is selected from one of a circular structure, a square structure, and a ring structure. In addition, the piezoelectric layer 13 can be externally connected to a unit such as a rectifier, a capacitor, etc. (not shown) for power storage. Since this is a power storage application at the back end of the power generation, it is a general technology in the field, and is not a technology of the present invention. Features are not described here. The locking member 12 is, for example, a block body, and has a plurality of positioning holes 12, and the cantilever 11 can be locked to the base 10 through the positioning holes 120 by screws or rivets, for example. ~ 11 surface, but not limited to this. For example, for assembly or processing convenience, the piezoelectric layer 13 can be clamped and fixed to the surface of the arm 11 by the clamping member 14, and the clamping member 14 is attached to the free sea 110494 of the two cantilever arms. 11 1345845 112 ' for holding the cantilever 11 and the piezoelectric layer 13. In this embodiment, the clamping member 14 includes: a symmetric clamping piece 14G, and a contact groove of each of the clamping pieces 140 corresponding to the cantilever u and the piezoelectric layer 13 and a groove 142 a plurality of positioning holes 144 for receiving and clamping the cantilever 11 and the piezoelectric layer 13 and passing through the positioning holes 144 to close and fix the two clamping pieces 140 to the two cantilever arms u End 112. The hollow carrier 15 is fixed to one side of the base 1 and is interposed between the suspensions 11. In this embodiment, the side of the base 10 is slid through the fixing bracket 16 as an example. And located in the middle region formed by the second cantilever u and corresponding to the free end 112 of the two cantilever u, while the center has a through passage 50. In the embodiment, the fixing bracket 16 includes two corresponding fixing clips 16〇, and the fixing clip 16 has one end clamping the hollow carrier 15 and the other end is inserted into the slot of the seat body 1〇. 1〇1, one end for clamping the hollow carrier 15 has a plurality of positioning holes for the locking screws to be clamped. The elastic reciprocating mechanism 17 is disposed in the channel 丄5〇 of the hollow carrier ,5, and has a mass 170 and two elastic members 172 respectively disposed at two ends of the mass 17〇, and the elastic member 172 The other end is abutted against the free end 112 of the cantilever 11. In this embodiment, the elastic member 172 is a compression spring, and the elastic member 172 holds the mass in a normal position in the center of the passage 150, and the external vibration is applied to the base. The mass 170 reciprocates in the channel 15〇. In the present embodiment, the hollow carrier 15 is 110494 12 1345845 round & The diameter of the channel 15〇 is slightly larger than the mass 17^\ to provide a gap between the mass 17〇 and the channel 150, reducing the friction between the bei block and the hollow carrier 15, and the quality is The block 170 smoothly reciprocates in the hollow carrier 15. Moreover, the section of the channel 150 of the hollow carrier 15 is, for example, circular, and the section of the mass may be circular 'but not limited thereto, as long as the mass 170 can be reciprocated. For example, a polygon with a regular hexagon. Applying the power generating device 1 of the present embodiment, since the mass 17 is only elastically positioned by the / and the two elastic members 172, the mass 170 is damaged once the power generating device is subjected to external vibration (for example, tapping or shaking). That is, a corresponding amplitude of vibration is generated, and reciprocating relative to the hollow carrier 丨 5 under the symmetry of the elastic member 172 of the two ends of the mass 17 correspondingly, the mass 17 is at both ends The elastic member 172 also generates a telescopic deformation and a pre-force due to the reciprocating motion of the mass 170, and thereby acts against the two cantilever arms u of the elastic member 172, so that the two cantilever arms u and the hooks are attached to the cantilever 11 The piezoelectric layer 13 (for example, a piezoelectric film) is warped to cause deformation, or the piezoelectric layer 13 (for example, a piezoelectric piece) corresponding to the elastic member 172 of the cantilever u is subjected to compression to cause deformation. The positive and negative charge centers of the piezoelectric layer 13 are relatively displaced to generate polarization, and the mechanical energy applied to the piezoelectric layer 13 is converted into electrical energy. In addition, the greater the vibration amplitude of the mass 170, the greater the force acting on the piezoelectric layer 13, the greater the degree of deformation of the piezoelectric layer 13, and the higher the frequency of action, the more energy can be generated by the crucible. Compared with the conventional piezoelectric power generation technology, the piezoelectric layer needs to be subjected to a large force of 13 110494 U45845 and a single external force extrusion or impact to generate a single deformation, resulting in a low deformation frequency and low power generation efficiency, and the like. The power generating device can reciprocate by using the elastic reciprocating mechanism and can act on the piezoelectric layer f to generate deformations to generate electric energy, which has better power generation performance and higher power generation efficiency. 2 is a schematic view of another embodiment of the power generating device of the present invention, wherein the same or similar components as those of the previous embodiment are denoted by the same or similar reference numerals, and the detailed description is omitted. In order to make the description of this case clearer and easier to understand. The greatest difference between this embodiment and the pre-embodiment is that the mass of the hollow carrier and the reciprocating mechanism of the bomb It has an electromagnetic induction effect. In this embodiment, the outer wall surface of the hollow carrier 15 is overlaid with a feeling, the coil 18' and the mass 17 is, for example, a magnetic body for the quality of the ghost 170 in the hollow carrier π channel The magnetic lines of force of the induction coil 18 are cut during relative reciprocation in 15 turns. The induction coil 18 is etched on the surface of the hollow carrier 15 but is not limited thereto. For example, the induction coil 18 may also be wound around the surface of the hollow carrier 15. The induction coil 18 can be externally connected to a unit such as a bridge rectifier, a capacitor (not shown) for power storage, and is a general-purpose technology in the field and is not a technical feature of the present invention. Therefore, it is not described here. When the power generating device 本 of the embodiment is applied, the mass 17 〇 is subjected to external action to generate a corresponding amplitude of vibration, and the elastic member 172 at both ends of the mass 170 ′ is opposite to the The hollow carrier 15 reciprocates. Similar to the previous embodiment, the mass 丨7〇, the elastic TL 172' of the two 110494 14 ends will act nu, causing the two cantilever u and the piezoelectric layer 13 of the cantilever 11 to be deformed, so that The piezoelectric layer 13 has a positive and negative charge t center relative displacement 'generating polarization, and the mechanical enthalpy applied to the dust raft 13 is converted into electric energy; meanwhile, at the mass HQ, reciprocating relative to the middle two carrier 15 During the movement, the magnetic lines of force of the induction coil 18 can be cut, resulting in a change in the magnetic flux of the induction coil 18, thereby generating electrical energy.发电 The power generation device 1 of the present embodiment can integrate the electromagnetic induction power generation technology and the C electric power generation technology, and greatly improve the power generation performance and efficiency compared to the single type of power generation method in the prior art. In summary, the power generating device of the present invention is characterized in that an elastic reciprocating mechanism having a mass and a two elastic members disposed at two ends of the mass is provided, and the two ends of the elastic reciprocating mechanism are provided. The cantilever of the piezoelectric layer, when the mass is reciprocated, can be applied to the C electric layer multiple times in a reciprocating manner to generate an opening and to generate electricity, and the greater the vibration amplitude, the effect on the dust layer The greater the force, and the higher the frequency of action of the piezoelectric layer, the more electrical energy can be generated. In order to avoid the need for the piezoelectric layer in the piezoelectric material power generation technology, the piezoelectric layer needs to be subjected to a large force, and the single force can only produce a single deformation, resulting in a low deformation frequency and low power generation efficiency. In addition, in the power generating device of the present invention, the surface of the hollow carrier accommodating the elastic reciprocating mechanism is provided with a plurality of induction coils for cutting the magnetic lines of the induction coil when the mass of the magnetic body is reciprocated, for example. The greater the vibration amplitude of the power generation, the greater the number of cutting magnetic lines and their frequencies, which can generate more electrical energy. Therefore, the power generating device of the present invention can integrate the electromagnetic induction power generation technology and the piezoelectric power generation 110494 15 1345845 • technology, and is added to a single type of power generation method in the prior art, which can greatly improve power generation performance and efficiency.
