Description

Technical Field

[0001] The invention relates to the technical field of lithium battery wrench energy replenishment, in particular to an emergency energy replenishment lithium battery wrench. Background Art

[0002] In the prior art, the power supply of electric wrenches mainly relies on built-in lithium batteries. Although lithium batteries have high energy density and long service life, in actual use, lithium batteries take a long time to charge, and once the battery is exhausted, the device will no longer be usable. In some outdoor operations or emergency environments, due to the lack of a fixed power source, users often have to carry spare lithium batteries to extend the use time of the device.

[0003] However, backup lithium batteries not only increase the burden on users to carry, but also cause problems such as inconvenient battery management and high cost of use. In addition, the traditional lithium battery charging method takes a long time, and it is difficult to restore power in time after the battery is exhausted, which affects the emergency application of the equipment. If you want to use it quickly, you need to prepare multiple lithium batteries, but the battery cost of lithium-powered wrenches is very expensive, and not every scenario requires the use of multiple batteries.

[0031] Alternatively, the energy storage module can be replaced by installing an auxiliary module that can charge the supercapacitor 220. The auxiliary module includes a generator 214 that can generate electrical energy and supply power to the supercapacitor 220. The input shaft of the generator 214 is connected to the rotating hand wheel 207 in a transmission manner, and the angle between the rotating hand wheel 207 and the input shaft of the generator 214 can be freely adjusted. The auxiliary component includes a generator housing 201 for fixing the generator 214. A sealed rotating disk 202 is fixed on the generator housing 201. A gear ring 216 is rotatably provided on the inner wall of the sealed rotating disk 202. A central gear 218 is rotatably provided at the center position of the inner wall of the sealed rotating disk 202. The central gear 218 and the gear ring 216 are meshed and transmitted through three planetary gears 217. The three planetary gears 217 are all rotatably provided on the sealed rotating disk 202. The central gear 218 is fixedly matched with the input shaft of the generator 214. An output rotating disk 215 is also rotatably provided on the sealed rotating disk 202. A sealing cover plate 213 is fixedly provided on the sealed rotating disk 202. The sealing cover plate 213 seals the output rotating disk 215 in the sealed rotating disk 202. An input gear 210 is rotatably provided at the center of the circle on the sealing cover plate 213. The input gear 210 and the output rotating disk 215 are fixedly transmitted via a rotating shaft. The output rotating disk 215 is fixedly matched with the gear ring 216. Two symmetrically arranged side gear brackets 211 are fixedly mounted on the sealing cover plate 213, a three-axis support frame 212 is rotatably mounted between the two side gear brackets 211, a rotating hand wheel 207 is rotatably mounted on the three-axis support frame 212 and the rotation axis of the side gear bracket 211, a floating gear 208 is fixedly arranged on the rotating hand wheel 207, an intermediate transmission side gear 209 is rotatably mounted on one of the side gear brackets 211, and the intermediate transmission side gear 209 is meshed with the input gear 210 and the floating gear 208 for transmission. A semicircular housing 204 is fixedly mounted on the sealing cover plate 213, a sliding hole 205 is opened in the middle of the semicircular housing 204, wherein the rotating hand wheel 207 is arranged in the sliding hole 205, a stable sliding sheet 206 is also slidably mounted on the sliding hole 205, and the stable sliding sheet 206 is rotatably matched with the rotating hand wheel 207.

[0032] The working principle of an emergency energy-replenishing lithium-powered wrench disclosed in the present invention is as follows: when the lithium battery 108 is out of power (if the lithium battery 108 is not fully charged, the use time will be shortened, for example, if the lithium battery 108 is forgotten to be fully charged before use), the two straps 102 are pulled apart, and then the base 103 and the buffer pad 109 are separated from the energy storage shell 101, and the lithium battery 108 is taken out. At this time, the dry battery top plate 113 is unfolded from the top plate placement groove 112, and dry batteries 110 are purchased in the surrounding supermarkets, and then placed in the energy storage shell 101, and the wrench 301 is powered (and then the base 103 is installed on the energy storage shell 101 through the straps 102). This situation is suitable for emergency situations. The lithium battery 108 can be charged during the use of the dry battery 110.

[0033] A supercapacitor 220 can also be installed in the handle of the wrench 301. When the lithium battery 108 is out of power, the supercapacitor 220 can be charged. Due to the characteristics of capacitance, the charging speed of the supercapacitor 220 will be much faster than the charging speed of the lithium battery 108. Then the insulating gasket 219 is pulled out from the strip jack 303 so that the pole ear of the supercapacitor 220 contacts the power supply contact of the wrench 301 (the supercapacitor 220 charges quickly and discharges quickly, so it needs to be charged frequently and is only suitable for emergency situations).

[0034] If there is no power supply outdoors, the user can carry an auxiliary module, install the generator housing 201 on the mounting threaded groove 223, and then rotate the rotating hand wheel 207. The rotating hand wheel 207 drives the floating gear 208 to rotate, and the floating gear 208 drives the intermediate transmission side gear 209 to rotate. The rotation of the intermediate transmission side gear 209 drives the input gear 210 to rotate. Since the intermediate transmission side gear 209 is arranged perpendicular to the input gear 210 and the floating gear 208, when the rotating hand wheel 207 swings, the rotation of the rotating hand wheel 207 can still drive the input gear 210 to rotate through the floating gear 208 and the intermediate transmission side gear 209, so that the rotating hand wheel 207 can drive the input gear 210 to rotate at different angles, so as to adapt to the user's habits, rather than letting the user adapt to the equipment. The rotation of the input gear 210 will drive the output rotating disk 215 to rotate, and the rotation of the output rotating disk 215 will drive the gear ring 216 to rotate. The rotation of the gear ring 216 will drive the central gear 218 to rotate through the planetary gear 217, and the rotation of the central gear 218 will drive the input shaft of the generator 214 to rotate, so that the generator 214 generates electrical energy, and then supplies power to the supercapacitor 220 through the charging device, and the supercapacitor 220 supplies power to the motor inside the wrench 301 through the discharge device. The generator 214 generates three-phase alternating current, and the three-phase alternating current is converted into direct current through a rectifier bridge. The rectifier bridge circuit is composed of 6 diodes, and each phase current passes through two groups of diodes (positive and negative half cycles) to achieve full-wave rectification. It also includes a matching system with an automatic voltage regulation function composed of a regulating IC (voltage regulator IC) and a sensor (voltage, speed and temperature sensor). By detecting the speed at which the user rotates the hand wheel 207, the voltage output by the generator is adjusted to ensure that the output voltage is always within a suitable range for charging at different operating speeds. The voltage regulator IC mainly adjusts and stabilizes the voltage according to the output voltage of the generator 214 to meet the charging requirements of the supercapacitor 220. The speed sensor (Hall effect sensor) monitors the speed of the generator 214 when the user rotates the hand wheel 207. The Hall effect sensor detects the speed by inducing changes in the magnetic field and is suitable for installation near the rotor of the generator 214. The voltage sensor (resistor voltage divider or voltage detection IC) detects the voltage output by the generator in real time and feeds the data back to the regulation IC. The voltage sensor can be a simple resistor voltage divider circuit or an integrated voltage detection IC (such as LTC2990). The temperature sensor (NTC thermistor) is used to detect the temperature of the supercapacitor 220 and the charging module to prevent overheating during charging. The higher the temperature of the NTC thermistor, the lower its resistance value, thereby providing temperature change information. The system temperature is monitored in real time through the temperature sensor, and the charging speed is automatically reduced or charging is stopped when the temperature exceeds the safe range to ensure system safety. When the user turns the hand wheel 207, the mechanical energy is transmitted to the generator 214 through the gear transmission system, so that it generates three-phase AC power.This AC power is converted into DC power through a rectifier bridge and provided to the supercapacitor 220. The output of the generator 214 is full-wave rectified through a diode rectifier bridge, converting the positive and negative waveforms of the AC power into pure DC output. This can avoid the problem of voltage instability caused by different rotation speeds of users and ensure that the supercapacitor can receive electrical energy continuously and stably. The integrated voltage matching module detects the rotation speed of the hand wheel 207 and then adjusts the output voltage of the generator 214. When the user rotates the hand wheel 207 at a low speed, the voltage matching module will reduce the load of the generator 214, making the voltage output more stable and avoiding energy waste at low speed; when the user rotates quickly, the system will appropriately increase the load to maximize the use of power generation capacity.

[0035] The discharge control of the supercapacitor 220 to the wrench 301 uses a MOSFET switch to control the discharge rate of the supercapacitor 220. Since the supercapacitor 220 discharges very quickly, a step-down conversion module needs to be added to smoothly convert the high voltage of the supercapacitor 220 into a voltage range available to the motor of the wrench 301. Among them, MOSFET (metal oxide semiconductor field effect transistor) is a component that controls the discharge of the supercapacitor 220. As an electronic switch, MOSFET can play a role of fast switching and current control in the circuit. During the discharge process of the supercapacitor 220, MOSFET can adjust the current passing through the motor of the wrench 301 to prevent the motor from being damaged due to sudden acquisition of a large amount of energy. By adjusting the gate voltage of the MOSFET, the discharge rate can be accurately controlled. The switching function of the MOSFET is that when the supercapacitor 220 does not reach the preset voltage, the MOSFET remains in the closed state to prevent current from flowing to the load. When the voltage reaches the preset value, the MOSFET is triggered and turned on, allowing current to flow to the motor of the wrench 301 and start discharging. By inputting a PWM signal (pulse width modulation) to the gate of the MOSFET through an intelligent controller (such as a PWM regulator), the on-time of the MOSFET can be adjusted, and then the output current intensity can be adjusted so that the current is adjusted according to the actual load demand of the motor in the wrench 301. At the same time, a current sensor can be connected in parallel with the MOSFET to monitor the output current of the supercapacitor 220 in real time. The current sensor feeds back the current information to the controller, and the controller adjusts the on-state of the MOSFET according to the actual situation.
