Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a power module, and in particular to a power module including a DC voltage source and a super capacitor, which can drive various types of power modules. Multifunctional tool with replaceable accessories. [Previous Technology] In today's life, many components need to be driven by short-wave power sources that are powered by electricity. For example, when driving a nail into wood, drilling a hole in a stone object, or driving a weeder or a vehicle's engine, high-torque operation is required. At this time, the peak power can be used to perform the above operation. Actions. In U.S. Patent Publication No. 5, 6 9.9, 7 800, B iss ο η ne 11 e discloses that by extending an elastic capsule and a fluid such as seawater, potential energy can be quickly converted into kinetic energy, thereby A pulse is generated, and the harpoon can be ejected by the generated pulse to pierce the fish in the water. In addition, pulses generated by DC power or AC power can also cause objects such as nails or staples to be ejected. For example, an electric nailing machine driven by a battery is disclosed in U.S. Patent Publication No. 6,1 3,87,7; in U.S. Patent Publication Nos. 4,5 5 8, 3,91 and 5, A battery-driven electric stapler is disclosed in Nos. 1, 5, 3, and 9; one is disclosed in U.S. Patent Publications Nos. 4,986,713, 5,818,186, and 6,086,304 Binding device. In general, tools driven by a DC power supply are convenient in operation because they do not require wires and are not limited by space, that is, they can be used away from the socket. In addition, tools driven by a DC power source do not need to endure voltage changes, while tools driven by an AC power source need not tolerate voltage changes. Furthermore, since straight

Description of the invention (2) The impact provided by the flow motor is directly driven rather than gear driven, so the impact provided by the DC motor will be greater than that provided by the AC motor Impact, so for a tool driven by a DC power source, the torque applied by the motor to the impact piston will be more accurate. In addition to being able to shoot objects, the pulse energy generated by the DC power source can also be converted into an impact force to perform engraving, Drilling, chopping, bending, clamping, pressing, crimping, crushing, embossing, perforating, punching, joining and impacting, etc. Many patents and commercial products can achieve the aforementioned actions, such as U.S. Patent Publication No. 4, 0 1 5, 6 7 1, 4, 4 6 8, 8, 2 6, 4, 579, 029, 4, 991, 472, 6, 427, 559, and 6, 4 6 0, 6 2 7 and so on are all related to battery-powered hand tools. In operation φ, the required force can be directly transmitted through the interaction between the piston and the elastic member (such as a spring). In another application, by direct current The pulse provided by the source can directly transmit a large current to perform welding operations, such as disclosed in US Patent Publication Nos. 4,801,780 and 6,225,596. In addition to using local electricity, it can also use The battery is used as a power source for a welder, a light source, or an emergency repair. In the conventional art, a portable power tool driven by a pulse widely uses a battery as a power source, and the battery is, for example, lead-sulfuric acid (Pb-H2S04). ) Heavy batteries, nickel-cadmium (N i-C d) batteries that are highly polluting to the environment, or nickel-metal hydride (N i-Μ Η) batteries with memory effects, etc. In order to provide sufficient It is necessary to install a large size and a large number of pulses, which will make the tool cumbersome. In addition, the circuit to generate the required pulses is very complicated, resulting in the success of the tool.

Although the aforementioned battery is a rechargeable battery, after a period of use, the battery's storage capacity will decrease and it will not be able to operate in a critical situation. At this time, the user must wait for several hours to perform the operation of the rechargeable battery, but may only have to complete a few minutes of work. [Summary of the Invention] Therefore, one of the objectives of the present invention is to provide a power module that can use a battery with a small capacity and a supercapacitor to output a desired pulse value, and the power module of the present invention can also be installed. Primary batteries (primaryce 1 1), such as alkaline batteries. In addition, when the power module of the present invention is installed on a power tool, the power tool will have the advantages of lightness, thinness, shortness, smallness, and easy portability. Therefore, using the battery module of the present invention, combined with the design of replaceable accessories, it is possible to develop a multi-functional portable tool using pulse driving to perform various tasks. According to the form of energy conversion, pulse-driven portable tools can be roughly divided into three categories: 1. The first type of tools can use pulses and mechanical components to shoot objects such as nails, staples or pin bolts. Perform the joining operation. 2 · The second type of tool is the use of pulses and mechanism components to provide impact force for scraping, striking, stamping, stamping, chopping, drilling, punching, joining or clamping. 3.

Another object of the present invention is to provide a method for generating a desired pulse.

l〇649twf.ptd Page 9 200421701 V. Description of the invention (4) The method can efficiently perform the above operations. Although the above work requires a large amount of energy, the super capacitor and the battery are connected in parallel through the control circuit. The power module can meet the requirements of the required power. Supercapacitors can also be referred to as ultracapacitors or electric double layer capacitors. Supercapacitors can accumulate a large amount of electrostatic charge ^ that is, up to several thousand can be accumulated in a small early capacitor. Farah. The electric charge stored in the super capacitor can be released instantaneously, thereby providing a huge current to drive the power tool. Because supercapacitors are lightweight, compact, tools driven by supercapacitors have excellent portability. Furthermore, because the cost of making various types of supercapacitors is very low, compared with the conventional method of increasing the output voltage of the battery through a boost converter, inductor or flywheel, using a supercapacitor to increase the output voltage of the battery will Has a better choice. Because the super capacitor has a particularly high power density, the output voltage of the DC voltage source can be increased by the super capacitor, even if the DC voltage source is a low power output device, such as a primary battery. In the power module of the present invention, the battery can charge the super capacitor, and the voltage output type of the super capacitor can be adjusted by a pulse width adjuster (PWM). In order to increase the service life of the battery, the battery will be discharged at a lower power, so the battery can meet the low power demand, and the super capacitor can meet the high power demand that the battery cannot provide. This can prevent the battery from outputting high power, so it can reduce the voltage drop of the battery and extend the battery life. In theory, after the super capacitor is fully charged, the voltage value provided by the super capacitor will be equal to the voltage value provided by the battery. So many

However, as the number of batteries increases, the power module of the tool can become even more cumbersome. Therefore, in the present invention, a plurality of individual super capacitors or super capacitor modules can be connected in parallel to perform the step of charging the super capacitor. When a pulse is required, all supercapacitors are temporarily switched to the series state and the supercapacitors are discharged. As mentioned above, the size and number of batteries can be reduced by charging supercapacitors in parallel. When the supercapacitor is switched to the series state for discharging, it can provide twice the voltage that the supercapacitor can provide to the portable tool in the parallel state. Only when the trigger and the electromagnetic relay are activated, the super capacitor will temporarily switch from the parallel state to the series state. In this way, it is not only simple and economical in the structure of electronic control, but also there will be no energy loss during battery power amplification. In the three embodiments in which the electronic pulse is applied in the present invention, the tool main body and the power supply module with replaceable parts can be integrally configured, and the replaceable parts can be easily engaged with the tool main body. In addition, replaceable parts and tool bodies can also be placed in the tool box, and the tool body can also be engaged with any replaceable parts for different tasks. In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is given below in conjunction with the accompanying drawings to make a detailed description as follows: [Embodiment] In today's daily life In China, electronic and non-electronic handheld devices are becoming more and more common and important. These handheld devices must not only meet the requirements of lightness, thinness, shortness, and smallness, but also provide multifunctional applications. For example, today ’s actions

10649t wf.pt d p.11 200421701 V. Description of the invention (6) The weight of the phone is less than 100 grams. However, in addition to the function of transmitting sound through the network, it can also have a digital camera (digita 1 sti 1 1 ca in era (DSC), and can transfer photos in real time through the network. As mentioned above, the size of portable devices is getting smaller and smaller, but more and more functions are added, so that the weight of the battery used to provide power to the portable device is even greater than the total of other components of the portable device. weight. In order to meet the current trend of portable devices, the power density and power generation of batteries must be continuously improved. However, the research and development of batteries can not always meet the current situation. Therefore, many energy-saving technologies have been developed to compensate for battery defects, such as low-power processors, automatic sensors, and standby mode systems. From a manufacturing and assembly point of view, supercapacitors are excellent electronic components that control the operation of battery energy. When supercapacitors are in a charged state, they can be used as energy registers or energy equalizers; when supercapacitors are in a discharged state Can be used as a power amplifier. Therefore, the present invention does not need to use a converter, a converter, a function generator, or an oscillating RCL circuit, and the super capacitor can amplify the power output of the battery to drive various tools. FIG. 1A shows a schematic diagram of an electric nailer 100 according to a first preferred embodiment of the present invention. The electric nailer 100 is driven by pulses provided by the power supply module, which can shoot various types of nails or pin bolts to perform the fixed work. The power supply module includes a battery and a super capacitor. By pressing the trigger 1 1 3, an object such as a nail or a pin can be ejected from the ejection outlet 1 1 0 of the nailer 1 0.

Using the pulse provided by the power module, the spring can be driven or compressed to its maximum position. When the spring bounces back to its original length, the electric nailer 100 can instantly provide an impulse to the nail or tip bolt, so that the nail or The tip bolt is removed from the storage box, and then the nail or tip bolt can be ejected from the electric outlet 1 100 of the electric nailer 100 to perform a fixed action. In addition, the accessory 1 1 6 and the adjustment screw 1 1 5 mounted on the top of the tool body 1 1 4 also have functions other than fixing. As shown in Figure 1B, by loosening the screws 1 1 5 and then reinstalling the screws 1 1 5, when the accessories 1 1 6 are locked, the bending anvil 1 2 2 is aligned with the injection port 1 1 0 , So it becomes electric stapler 1 02. By pressing the trigger 113, the U-shaped stapler can be ejected from the electric stapler 102 and pass through the paper stacked between the ejection opening 1 1 0 and the bending anvil 1 2 2 Used for binding (not shown in Figure 1B). After the staple passes through the stacked paper, the staple is bent into the groove of the bending anvil 1 2 2 and both ends of the staple are bent to the last page of the stacked paper This completes the binding work. In FIG. 1B, a plurality of notches 1 2 4 are also shown, which are located on the accessory 1 1 6 so that the ejection opening 1 1 0 and the bending anvil 1 2 2 can be adjusted according to the thickness of the paper stack. Pitch. As described above, the electric stapler 100 and the electric stapler 102 can not only use the same tool body 1 1 4 and the power module assembled in the detachable container 1 1 1, but also the nails, pins and staples. The staples can also go through a common path. As described above, the use mode f of the electric stapler 100 and the electric stapler 102 can be switched by the accessory 1 16, so the present invention can achieve the design objective that a tool can have two functions.

l〇649twf.ptd Page 13 200421701 Five dry sounds Figure 2 shows a diagram of a power module 200 according to a preferred embodiment of the present invention. Using the power module 200 can provide pulses to drive Electric ^ ^, for shooting objects, providing impulse, and transmitting peak current. The circuit in block 240 can instantly drive the aforementioned electric stapler 100 or electric stapler 1 q 2 and borrow The circuit in block 2 6 q can provide a large current to drive a larger load, of which block 2 4 0 and block 2 6 0 can be used together to use super capacitors 2 07, 2 08, and electricity. Station S1—S4. Super capacitor

2 0 ^, 2 0 8 can also be called extreme capacitors or electric double-layer capacitors. Super capacitor I can accumulate a large amount of electrostatic charge, that is, up to thousands of farads can be accumulated in a small single capacitor. The circuits in blocks 240 and 260 also include a power regulator 230, which can control the power output of the power supply to meet the workload. When the switch 2 0 2 is switched to the states of a 1 and a Γ, the circuit in block 2 40 will be driven, and the DC voltage source 2 0 1 can be connected to the super capacitor through the electrical connection of the contacts S 1 a and S 1. 2 0γ is charged, and the super capacitor 208 is charged through the electrical connection of the contacts S3a, S3. The diode 203 can prevent the current output by the supercapacitors 2007 and 2008 from flowing back to the DC voltage source 201. The contacts SI, Sla, S3, and S3a are four of the 12 contacts of the electromagnetic relay station with four ports, and the contacts s 1 to S 4 are common contacts. The port system is a single-pole double-throw switch (SPDT). Four of the 12 contacts (S1-Sla, S2-S2a, S3-S3a, S4-S4a) are normally closed, while the other four are normally closed. Groups (SI-Sib, S2-S2b, S3-S3b, S4-S4b) are normally open. When the super capacitors 207 and 208 are charged, the super capacitors 207 and 208 can be connected in parallel. The working voltage provided by the DC voltage source 2 01 will be slightly

10649lwf.ptd Page 14 200421701 V. Description of the invention (9) It is greater than the working voltage provided by the supercapacitors 207 and 208, and it is far less than the driving voltage required by the pulse drive tool motor 209, so DC The size or number of the voltage sources 2 0 1 can be reduced. When the trigger of the tool is depressed, the relay will switch from the normally closed state to the normally open state. Therefore, the super capacitors 2 0 7 and 2 8 will be connected in series to discharge to the motor, and the pulse received by the motor It will be twice the discharge voltage of any of the super capacitors 207 and 208. After discharging, the supercapacitors 207 and 208 will return to the parallel state and perform the work of charging the supercapacitors 207 and 208. If the tool has to meet the requirements of different powers, Beij can meet this demand with the power selector 2 1 0. For example, the power selector 2 1 0 has three power levels A, B, and C, which can select low, medium, and high power output respectively. The power level of the power selector 2 1 0 is determined by the resistance 2 2 2, φ 2 2 The resistance value of 3, 2 2 4 is determined, where the lower the resistance value of the resistor, the higher the output power level. When the switch 2 0 is switched to a 1 and a Γ, the DC voltage source will provide the voltage to the selector 2 10 through the contact a 1. When the voltage provided by the DC voltage source is divided by one of the resistors 222, 223, and 224 and the resistor 211, it is provided to the non-inverting input differential amplifier 214. After comparing the input divided voltage with the internal reference voltage in the amplifier 214, a differential voltage will be generated as the output terminal of the differential amplifier 214, where the differential voltage will be according to the resistance values of the resistors 2 1 3 and 2 1 2 Zoom in. The output voltage of the differential amplifier 214 will be equal to the input voltage of the pulse width adjuster 2 1 5 (P WM). According to the selected power level A, B, C, the input voltage of the pulse width adjuster 215 will Jumping to three levels of low, medium, and high, so that the pulse widths produced by the pulse width adjuster 2 15 will form narrow, medium, and wide forms, respectively. N-channel field effect transistor

106491 w fp td Page 15 200421701 V. Description of the Invention (217) (N-channel FET) will determine the turn-on time according to the trigger pulse width transmitted from the pulse width adjuster 215, among which the field effect transistor 2 The gate of 1 7 is electrically connected to the pulse width adjuster 2 1 5. In other words, according to the narrow, medium, and wide pulse widths output by the pulse width adjuster 2 1 5, the short, medium, and long opening times of the field effect transistor 2 1 7 are controlled, respectively. By controlling the opening time of the field effect transistor 2 1 7, the short, medium and high level pulses received by the motor 2 09 can be determined. With the power regulator 2 3 0 described above, it is possible to protect, for example, the material of the paper from being damaged by excessive force. When the switch 2 0 is switched to a 2 and a 2 ′, the power module is switched to use the circuit in block 260. When switching to the circuit in block 260 for operation, the charging and discharging process of the supercapacitors 207 and 208 is the same as switching to the circuit in block ψ 2 40 for operation, as described above. However, when switching to the circuit operation in block 260, the relays S4 and S4 are driven by the switch 204, not by the trigger 205. In addition, the booster circuit 2 1 9 is also electrically connected to the DC voltage source 2 01. When the super capacitors 2 0 7 and 2 8 are switched to a series connection through the relays S 1 to S 3, the booster circuit 2 19 will be electrically connected in parallel with the super capacitors 207 and 208 connected in series. The booster circuit 2 1 9 can increase the voltage provided by the DC voltage source 2 01, and the boosted voltage can drive a load electrically connected to the connector 2 2 1. The power of the DC voltage source 201 can be amplified by the booster circuit 2 1 9 as a backup power source for the super capacitors 207 and 208, so as to compensate for the rapid voltage drop when the super capacitors 2 07 and 2 8 are discharged. Although the power output of the backup power supply is insignificant compared to the power output of the super capacitors 207 and 208, especially when driving a large load, such as when starting a car with a dead battery, the backup power supply The power provided will be sent

In addition, in addition to the electromagnetic relays, the types of relays S 1 to S 4 can be solid state relays (SSR) or solenoids (s ο 1 e η 〇id), etc., and the super capacitor 2 can be switched. 0 7, 2 0 8 status. The power supply module 200 of the present invention can meet the aforementioned application requirements. In the power module 200, the DC voltage source 201 and the super capacitors 207 and 208 can reach a balanced state during discharge, so the power module 200 can provide a specific power density in a compact size, for example, more than 1KW / Kg. Another advantage of the present invention is that the DC voltage source 2 01 can be discharged at a low voltage, such as φ. This can reduce the voltage drop of the DC voltage source 2 01, and can extend the use time of the DC voltage source 201. The ultracapacitors 207 and 208 can provide high power output that cannot be achieved by the DC voltage source 021.

In addition, by controlling the energy storage value of the DC voltage source and the super capacitor, the output power and usage time of the portable power supply can be adjusted. Next, an embodiment of the power module is described. The power module 2 0 in FIG. 2 may be composed of a lithium battery and a super capacitor, for example, a lithium battery having eight types 1 8 6 50 (The radius is 18mni and the length is 65 mm), it is a 2 S 4 P structure, that is, two batteries are connected in series as a group, and then the four battery groups are connected in parallel, and each The battery, for example, can provide a voltage of 3.7 volts, and has a capacity of 20,000 in Ah and a comparable internal resistance.
