[0002] In existing technology, electric wrenches primarily rely on built-in lithium batteries for power. While lithium batteries offer high energy density and a long service life, they take a long time to charge in practice, and once depleted, the device becomes unusable. In some outdoor operations or emergency situations, where there's no fixed power source, users often carry backup lithium batteries to extend the device's operating time.

Furthermore, traditional lithium battery charging takes a long time, and after depletion, it's difficult to restore power in a timely manner, hindering emergency applications. For quick use, multiple lithium batteries are necessary, but lithium-powered wrench batteries are very expensive, and not every scenario requires multiple batteries. Summary of the Invention

[0031] Alternatively, the energy storage module can be replaced with an auxiliary module that can charge the supercapacitor 220. The auxiliary module includes a generator 214 that can generate electricity and power the supercapacitor 220. The input shaft of the generator 214 is connected to the rotating handwheel 207, and the angle between the rotating handwheel 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 turntable 202 is fixed to the generator housing 201. The inner wall of the sealed turntable 202 is rotatably provided with a gear ring 216. The center position of the inner wall of the sealed turntable 202 is rotatably provided with a central gear 218. The central gear 218 and the gear ring 216 are meshed and driven by three planetary gears 217. The three planetary gears 217 are all rotatably provided on the sealed turntable 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 turntable 202. A sealing cover plate 213 is fixedly provided on the sealed turntable 202. The sealing cover plate 213 encloses the output rotating disk 215 in the sealed turntable 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 driven by 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 bracket 212 is rotatably mounted between the two side gear brackets 211. A rotating handwheel 207 is rotatably mounted on the three-axis support bracket 212 and perpendicular to the rotation axis of the side gear brackets 211. A loose gear 208 is fixedly mounted on the rotating handwheel 207. An intermediate transmission side gear 209 is rotatably mounted on one of the side gear brackets 211. The intermediate transmission side gear 209 meshes with the input gear 210 and the loose gear 208. A semicircular housing 204 is fixedly mounted on the sealing cover plate 213. A sliding slot 205 is defined in the center of the semicircular housing 204. The rotating handwheel 207 is mounted in the sliding slot 205. A stabilizing sliding plate 206 is also slidably mounted on the sliding slot 205. The stabilizing sliding plate 206 rotatably engages with the rotating handwheel 207.

[0032] The working principle of an emergency energy-replenishing lithium-ion 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 you forget to fully charge the lithium battery 108 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 slot 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 to charge the supercapacitor 220 when the lithium battery 108 is out of power. Due to the characteristics of capacitance, the supercapacitor 220 charges much faster than the lithium battery 108. Then, the insulating gasket 219 is pulled out from the strip jack 303 so that the tabs of the supercapacitor 220 contact the power supply contacts of the wrench 301 (the supercapacitor 220 charges 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 handwheel 207. The rotating handwheel 207 drives the loose gear 208 to rotate, and the loose 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 loose gear 208, when the rotating handwheel 207 swings, the rotation of the rotating handwheel 207 can still drive the input gear 210 to rotate through the loose gear 208 and the intermediate transmission side gear 209, so that the rotating handwheel 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 input gear 210 drives the output rotating disk 215, which in turn drives the ring gear 216. The rotation of ring gear 216 drives the sun gear 218 via planetary gears 217, which in turn drives the input shaft of generator 214. This generates electricity, which is then used to power supercapacitor 220 via a charging device. Supercapacitor 220 then powers the motor inside wrench 301 via a discharging device. Generator 214 generates three-phase AC power, which is converted to DC power via a rectifier bridge. The rectifier bridge circuit consists of six diodes, with each phase of current passing through two sets of diodes (positive and negative half-cycles) to achieve full-wave rectification. It also includes a matching system with automatic voltage regulation, consisting of a regulator IC (voltage regulator IC) and sensors (voltage, speed, and temperature sensors). By detecting the speed at which the user rotates handwheel 207, it adjusts the generator output voltage, ensuring that the output voltage remains within a suitable charging range at different operating speeds. The voltage regulator IC primarily adjusts and stabilizes the output voltage of generator 214 to meet the charging requirements of supercapacitor 220. A speed sensor (Hall-effect sensor) monitors the speed of generator 214 when the user rotates handwheel 207. This sensor detects speed by sensing changes in the magnetic field and is ideally mounted near the rotor of generator 214. A voltage sensor (resistor divider or voltage detection IC) monitors the generator's output voltage in real time and feeds this data back to the regulator IC. This voltage sensor can be a simple resistor divider circuit or an integrated voltage detection IC (such as the LTC2990). A temperature sensor (NTC thermistor) monitors the temperature of supercapacitor 220 and the charging module to prevent overheating during charging. The higher the temperature of the NTC thermistor, the lower its resistance, providing temperature information. The temperature sensor monitors system temperature in real time and automatically reduces or stops charging when the temperature exceeds a safe range, ensuring system safety. When the user rotates handwheel 207, mechanical energy is transferred to generator 214 through a gear transmission system, generating three-phase AC power.This AC power is converted into DC power through a rectifier bridge and supplied to the supercapacitor 220. The output of the generator 214 is full-wave rectified by a diode rectifier bridge, converting the positive and negative waveforms of the AC power into a pure DC output. This can avoid voltage instability caused by different rotation speeds of the user and ensure that the supercapacitor can continuously and stably receive electrical energy. The integrated voltage matching module detects the rotation speed of the handwheel 207 and then adjusts the output voltage of the generator 214. When the user rotates the handwheel 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 speeds; 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. Because the supercapacitor 220 discharges extremely quickly, a step-down converter module is required to smoothly convert the high voltage of the supercapacitor 220 into a voltage range suitable for the wrench 301 motor. The MOSFET (metal oxide semiconductor field effect transistor) is the component that controls the discharge of the supercapacitor 220. As an electronic switch, the MOSFET can perform fast switching and current control functions in the circuit. During the discharge process of the supercapacitor 220, the MOSFET can regulate the current passing through the wrench 301 motor to prevent the motor from being damaged by a sudden increase in energy. By adjusting the gate voltage of the MOSFET, the discharge rate can be precisely controlled. The switching function of the MOSFET is that when the supercapacitor 220 does not reach the preset voltage, the MOSFET remains in the off state, preventing current from flowing to the load. When the voltage reaches the preset value, the MOSFET is triggered and turns on, allowing current to flow to the wrench 301 motor and starting the discharge. By inputting a PWM signal (pulse width modulation) to the gate of the MOSFET through an intelligent controller (such as a PWM regulator), the MOSFET's on-time can be adjusted, thereby regulating the output current intensity, so that the current is adjusted according to the actual load requirements of the motor in the wrench 301. A current sensor can also be connected in parallel with the MOSFET to monitor the output current of the supercapacitor 220 in real time. The current sensor feeds current information back to the controller, which adjusts the MOSFET's conduction state based on the actual situation.
