Description

Power modules to generate various types of pulses

technical field

The present invention relates to a power supply module in a power supply or power distribution circuit device in the electrical field, in particular to a power supply module including a DC voltage source and a supercapacitor, which can drive a variety of replaceable accessories Power module for generating various types of pulses (POWER MODULE FOR GENERATING IMPULSES OF VARIOUS LEVELS).

Background technique

In today's life, many components need to be driven by over-power and short-pulse power. For example, when driving a nail into wood, drilling a hole in a stone object, or trying to drive the engine of a lawnmower or a vehicle, high torque is required and must be done with peak power. Actions. In U.S. Patent Publication No. 5,699,780, bissonnette disclosed that by means of an extended elastic bladder and a fluid such as sea water, potential energy can be quickly converted into kinetic energy to generate a pulse, and the generated pulse can be ejected A harpoon, used to stab fish in the water. In addition, objects such as nails or staples can also be ejected by pulses generated by DC power or AC power. For example, US Patent No. 6,173,877 discloses a battery-driven electric stapler; US Patent Nos. 4,558,391 and 5,105,329 disclose a battery-driven electric stapler; A binding device is disclosed in US Patent Publication Nos. 4,986,713, 5,818,186 and 6,086,304. Generally speaking, tools driven by a DC power source do not require wires and are not limited by space, that is, they can be used at a location far away from the socket, so they are more convenient to operate. Moreover, tools driven by a DC power source do not need to endure voltage fluctuations, but tools driven by an AC power source need to endure voltage fluctuations. Furthermore, since the impact provided by the DC motor is directly driven rather than gear driven, the impact provided by the DC motor will be greater than that provided by the AC motor. The torque on the impact piston will be more positive.

In addition to shooting objects, the pulse energy generated by the DC power supply can also be converted into impact force to perform engraving, drilling, chopping, bending, clamping, pressing, crimping, crushing, embossing, perforating, Actions such as stamping, joining and impacting. Many patents and commercial products can achieve the aforementioned actions. For example, US Patent No. 4,015,671, No. 4,468,826, No. 4,579,029, No. 4,991,472, No. 6,427,559 and No. 6,460,627 are all related to battery-driven hand tools. In operation, the required force can be directly transmitted through the interaction between the piston and the elastic member (such as a spring). In another application, the pulses provided by the DC power supply can directly transmit high current to perform the welding action, such as disclosed in US Patent Nos. 4,801,780 and 6,225,596. In addition to being able to use city power, the battery can also be used as a power source for welders, lights or emergency repairs.

In the prior art, portable electric tools driven by pulses widely use batteries as power sources, where batteries are, for example, heavy batteries (heavy batteries) composed of lead-sulfuric acid (Pb-H ₂ SO ₄ ), Nickel-cadmium (Ni-Cd) batteries with high environmental pollution, or nickel-metal hydride (Ni-MH) batteries with memory effects, etc. In order to provide enough pulses, a large number of batteries must be installed, which makes the tool bulky. In addition, the circuitry by which the required pulses are generated is complex, leading to increased tool costs. Although the aforementioned battery is a rechargeable battery, after a period of use, the storage capacity of the battery will decrease, making it impossible to operate in an emergency. At this time, the user has to wait several hours for the action of charging the battery, but may only complete the work for several minutes.

It can be seen that the above existing power supply module for generating pulses still has many defects, and further improvement is urgently needed.

In order to solve the problems of the power modules that generate pulses, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above problems. This is obviously a problem that relevant industry players are eager to solve.

In the aforementioned power module, the structures of the capacitors are one of supercapacitors, extreme capacitors and electric double layer capacitors.

Compared with the prior art, the present invention has obvious advantages and beneficial effects. As can be seen from the above technical solutions, the content of the present invention

One of the technical solutions of the present invention is to provide a power module that can use a battery with a smaller capacity and a supercapacitor (supercapacitor) to output the desired pulse value, and the power module of the present invention can also be installed with a primary cell, such as It is an alkaline battery. In addition, when the power module of the present invention is installed on the electric tool, the electric tool will have the advantages of being light, thin, short, small and easy to carry. Therefore, by using the battery module of the present invention, combined with the design of replaceable accessories, a multifunctional portable tool driven by pulses can be developed to perform various tasks.

According to the form of energy conversion, portable tools driven by pulses can be roughly divided into the following three categories:

1. The first type of tool uses pulse and mechanism components to shoot objects such as nails, staples or pins, so as to perform joint actions.

2. The second type of tool uses pulse and mechanism components to provide impact force to perform actions such as scraping, tapping, stamping, embossing, chopping, drilling, perforating, joining or clamping.

3. The third type of tool is to use the pulse to directly transmit the surge or peak current, so as to activate the engine, weld metal or start various machines.

Another technical solution of the present invention is to provide a power module, which can provide a method for generating the required pulses, and can efficiently perform the above-mentioned operations. Although the above-mentioned operations require relatively large energy, by having a super capacitor And the power supply module connected in parallel with the battery through the control circuit can meet the demand of the required power supply.

The supercapacitor can also be called an extreme capacitance (ultracapacitor) or an electric double layer capacitor (electric double layer capacitor), and a large amount of electrostatic charge can be accumulated by a supercapacitor, that is, it can accumulate up to thousands of static charges in a single capacitor with a small volume. Farah. The charge stored in the supercapacitor can be released instantly to provide a huge current to drive the electric tool. Since supercapacitors are light, small and compact, tools driven by supercapacitors will have excellent portability. Furthermore, since the cost of making various types of supercapacitors is very low, compared to the conventional method of increasing the output voltage of the battery by boost converters, inductors or flywheels, the use of supercapacitors to increase the output voltage of the battery The output voltage would have a better choice. Since the supercapacitor has a particularly high power density, the output voltage of the DC voltage source can be increased by the supercapacitor, 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 supercapacitor, and the voltage output type of the supercapacitor can be adjusted by a pulse width regulator (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. In this way, the battery can be prevented from outputting high power, so the voltage drop of the battery can be reduced and the service time of the battery can be prolonged.

Theoretically, after the supercapacitor is fully charged, the voltage value provided by the supercapacitor will be equal to the voltage value provided by the battery. Therefore, many batteries are arranged in series to achieve the desired charging voltage. However, while increasing the number of batteries, the power module of the tool will also become very bulky. Therefore, in the present invention, multiple individual supercapacitors or supercapacitor modules can be connected in parallel to perform the step of charging the supercapacitors. When it is necessary to provide a pulse, all supercapacitors are temporarily switched into a series state, and the supercapacitors are discharged. As mentioned above, by charging supercapacitors in parallel, the size and number of batteries can be reduced. When the supercapacitor is switched into a 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 act, the supercapacitor will temporarily switch from the parallel state to the series state. In this way, not only is the electronic control structure very simple and economical, but also there will be no energy loss when the battery power is amplified.

In the three implementations of the application of electronic pulses in the present invention, the tool body with replaceable accessories and the power module can be integrally configured, and the replaceable accessories can be easily engaged with the tool body. In addition, the replaceable accessories and the tool body can also be placed in the tool box, and the tool body can also be combined with any replaceable accessory to perform different tasks.

In summary, the present invention is used to generate various types of pulse power supply module, which mainly provides pulses through the combination of batteries and supercapacitors, so as to drive various multi-function tools. There are three applications through the driving of pulses Ways, such as ejecting objects, providing impact force, or providing a peak current greater than 100A. The power output of the power module can be increased by the supercapacitor. When the supercapacitor is connected in parallel, the DC voltage source can charge the supercapacitor. When the trigger of the tool is pressed, the supercapacitor will be switched to series connection and discharged. Therefore, the number of batteries used to drive the portable tool can be reduced, and the design of the switch for controlling the parallel connection and the series connection is very simple, which can reduce the cost. With a tool main body plus replaceable accessories and the power supply module of the present invention, work and maintenance at home or in the field can be performed.

The present invention has the advantages and practical value mentioned above, and no similar structural design has been published or used in similar products, and it has great improvements in both structure and function, and has a great technical advantage. The progress of the invention has produced easy-to-use and practical effects, and indeed has enhanced efficacy, so that it is more suitable for practical use. It is a novel, progressive and practical new design.

Detailed ways

The specific implementation, structure, features and functions of the power module for generating various types of pulses according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

In today's daily life, electronic and non-electronic handheld devices are becoming more and more common and important. These handheld devices must not only meet the requirements of being light, thin, short, and small, but also provide multi-functional applications. For example, the weight of today's mobile phones is less than 100 grams. However, in addition to the sound transmission through the network, it can also have the function of a digital camera (digital still camera, DSC), and can take pictures through the network. Real-time transmission. As mentioned above, the size of portable devices is getting smaller and smaller, but more and more functions have been added, so that the weight of the battery used to provide power for the portable device is even greater than the sum of other components of the portable device the weight of. In order to meet the current trend of portable devices, it is necessary to continuously improve the power density and power generation capacity of batteries. However, the research and development of batteries cannot always meet the current situation, so many energy-saving technologies have been developed to compensate for the shortcomings of batteries, such as low-power processors, automatic sensors, and standby mode systems. From the point of view of manufacturing and assembly, supercapacitor is an excellent electronic component to control the energy operation of the battery. When the supercapacitor is in the charging state, it can be used as an energy buffer or energy equalizer; when the supercapacitor is in the discharging 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, but uses a supercapacitor to amplify the power output of the battery to drive various tools.

Please refer to FIG. 1A , which is a schematic structural diagram of an electric nail driver 100 according to a first preferred embodiment of a power module for generating various types of pulses according to the present invention. The electric nail driver 100 is driven by the pulse provided by the power module, so as to eject various forms of nails or pins for fixing work, wherein the power module includes a battery and a super capacitor. By pressing the trigger 113 , an object such as a nail or a pin can be ejected from the ejection port 110 of the nailer 100 , and the power module placed in the detachable container 111 will discharge at this moment. The user can easily hold the tool 100 and move the electric nailer 100 through the handle 112, and the tool body 114 also includes a plurality of mechanical devices, such as a motor, a gear set and a spring (not shown in FIG. 1A ). . Using the pulse provided by the power module, the spring can be driven or compressed to the maximum position. When the spring bounces back to the original length, the electric nailer 100 can instantly provide an impact force to the nail or pin, thereby driving the nail or pin The bolt is removed from the storage box, and then the nails or pins can be ejected from the injection port 110 of the electric nailer 100 to carry out the fixing action.

In addition, the attachment 116 and the adjustment screw 115 attached to the tip of the tool main body 114 have other functions than fixing. Please refer to FIG. 1B , by loosening the screw 115 and reinstalling the screw 115, when the accessory 116 is locked, the bending anvil 122 can be aligned with the injection port 110, so that it can become an electric stapler. Machine 102. By pressing the trigger 113, the U-shaped staples can be ejected from the electric stapler 102, and pass through the paper stacked between the ejection port 110 and the bending anvil 122, so as to carry out the work of binding (not shown). is shown in Figure 1B). After the staple has passed through the stack of sheets, the staple will be bent in the groove of the anvil 122 and both ends of the staple will be bent onto the last page of the stack of sheets , so that the binding work is completed.

In FIG. 1B , a plurality of notches 124 are also shown, which are arranged on the accessory 116 , so that the distance between the injection port 110 and the bending anvil 122 can be adjusted according to the thickness of the stacked paper.

As described above, the electric stapler 100 and the electric stapler 102 can not only share the same tool body 114 and the power module assembled in the detachable container 111, but also nails, pins and staples can also be used together. through a common path. As mentioned above, the use mode of the electric stapler 100 and the electric stapler 102 can be switched through the accessory 116, so the present invention can achieve the design purpose that one tool can have two functions.

Please refer to FIG. 2 , which is a schematic diagram of a power module 200 according to a preferred embodiment of the present invention. The power module 200 can provide pulses to drive the electric tool to perform operations such as ejecting objects, providing impact force, and transmitting peak current. The aforementioned electric stapler 100 or electric stapler 102 can be driven instantaneously by the circuit in block 240, and a larger current can be provided by the circuit in block 260 to drive a larger load, wherein, block 240 And block 260 can use supercapacitors 207, 208 and relays S1-S4 together. The supercapacitors 207 and 208 can also be called extreme capacitors or electric double layer capacitors, and a large amount of electrostatic charges can be accumulated by supercapacitors, that is, thousands of farads can be accumulated in a single capacitor with a small volume. The circuit in the block 240 and the block 260 also includes a power regulator 230, which can control the power output of the power supply to match the working load. When the switch 202 is switched to the state of a1, a1', the circuit in the block 240 will be driven, and the DC voltage source 201 can charge the supercapacitor 207 through the electrical connection of the contacts S1a and S1, and the electrical connection through the contacts S3a and S3 The connection charges the supercapacitor 208. The current output by the supercapacitors 207 and 208 can be prevented from flowing back to the DC voltage source 201 by the diode 203 . The contacts S1, S1a, S3, and S3a are four of the 12 contacts of the electromagnetic relay with four ports, wherein the contacts S1-S4 are common contacts, and each port is a single-pole double-throw switch (SPDT), four of the 12 contacts (S1-S1a, S2-S2a, S3-S3a, S4-S4a) are normally closed, while the other four (S1-S1b, S2- S2b, S3-S3b, S4-S4b) are normally open. When charging the supercapacitors 207 and 208, the supercapacitors 207 and 208 can be connected in parallel, and the working voltage provided by the DC voltage source 201 will be slightly greater than the working voltage provided by the supercapacitors 207 and 208, but far less than that of the pulse-driven tool. The driving voltage required by the motor 209, so the size or number of the DC voltage source 201 can be reduced. When the trigger 205 of the tool is pressed, the relay will switch from the normally closed state to the normally open state, so the supercapacitors 207, 208 will be connected in series to discharge to the motor, and the pulse received by the motor will be twice that of either The discharge voltage of the supercapacitors 207, 208. After being discharged, the supercapacitors 207 and 208 will return to the state of being connected in parallel to charge the supercapacitors 207 and 208 .

If the tool needs to meet different power requirements, the power selector 210 can satisfy this requirement. The power selector 210, for example, has three power levels A, B, and C, which can select low, medium, and high power outputs respectively, and the power level of the power selector 210 is determined by the resistance values of the resistors 222, 223, and 224 Determined, wherein when the resistance value of the resistor is lower, the output power level will be higher. When the switch 202 is switched to a1 and a1', the DC voltage source will provide voltage to the selector 210 through the contact a1. After the voltage provided by the DC voltage source is divided by one of the resistors 222 , 223 , 224 and the resistor 211 , it will be 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 is generated as the output of the differential amplifier 214 , wherein the differential voltage is amplified according to the resistance ratio of the resistors 213 and 212 . The voltage at the output of the differential amplifier 214 will be equal to the voltage at the input of the pulse width modulator 215 (PWM). According to the selected power level A, B, C, the voltage at the input of the pulse width modulator 215 will jump to low , middle and high levels, so that the pulse width generated by the pulse width adjuster 215 will form narrow, medium and wide forms respectively. The N-channel field effect transistor 217 (N-channel FET) will determine the turn-on time according to the trigger pulse width transmitted from the pulse width regulator 215, wherein the gate of the field effect transistor 217 is connected with the pulse width regulator 215 is electrically connected. In other words, according to the narrow, medium and wide pulse widths output by the pulse width regulator 215, the short, medium and long turn-on times of the field effect transistor 217 are respectively controlled. By controlling the turn-on time of the field effect transistor 217, the short, medium and high level pulses received by the motor 209 can be determined. The aforementioned power regulator 230 can protect materials such as paper from being damaged by excessive force.

When the switch 202 is switched to a2 and a2', the power module will switch to use the circuit in the block 260. When switching to the circuit operation in block 260, the charging and discharging process of the supercapacitors 207, 208 is the same as switching to the circuit operation in block 240, as described above. However, when switching to the operation of the circuit in block 260 , the relays S1 - S4 are driven by the switch 204 instead of the flip-flop 205 . In addition, the boost circuit 219 is also electrically connected to the DC voltage source 201.
