[0051] Referring to Figure 1 , Figure 1 It is a structural schematic view of the first embodiment of the utility model self-powered battery.

[0052] The utility model proposes the first embodiment of self-powered battery.

[0053] In the embodiment, the battery with self-power generation function comprises a battery shell 2 provided with a knob 1 at the tail, a power generation element 10 and an energy storage element 20; the power generation element 10 is arranged at one end of the battery shell 2 close to the knob 1, the energy storage element 20 is arranged at one end of the battery shell 2 away from the knob 1, the input end of the power generation element 10 is connected with the knob 1, the output end of the power generation element 10 is electrically connected with the input end of the energy storage element 20, and the output end of the energy storage element 20 is connected with the positive electrode of the battery.

[0054] It should be noted that the power generation element 10 can be used to generate power supply electric energy when the knob 1 rotates, and transmit the power supply electric energy to the energy storage element 20; the energy storage element 20 can be used to store the received power supply electric energy, and output the stored electric energy to supply power to the outside during the discharge process of the battery.

[0055] It should be noted that the knob 1 can be a flat knob or a cam knob, and the power generation element 10 is driven to work by rotating the knob 1. The power generation element 10 can be a device capable of converting mechanical energy into direct current electric energy, such as a manual direct current generator. The rotor of the generator is driven to rotate by hand, and then electric energy is generated. The core principle of the manual direct current generator is electromagnetic induction, and the basic components include a stator and a rotor. The stator is usually a permanent magnet, and the rotor is a coil. Under the action of external force (such as turning the knob by hand), the rotor coil cuts the magnetic induction lines in the magnetic field, thereby generating an induced electromotive force. If the internal coil forms a closed loop with the external circuit through the brush, an electric current will be formed in the circuit.

[0056] Further, the battery shell 2 can be a cylindrical battery, such as a common battery which can include a No. 5 battery (a battery shell conforming to the No. 5 battery standard, with a diameter of about 14 mm and a height of about 50 mm) and a No. 7 battery (a battery shell conforming to the No. 7 battery standard, with a diameter of about 10 mm and a height of about 45 mm), etc., which is not specifically limited in the embodiment. Corresponding to the battery shell, the diameters of the power generation element 10 and the energy storage element 20 need to be slightly smaller than the diameter of the battery shell 2. Taking the No. 5 battery standard as an example, the diameters of the power generation element 10 and the energy storage element 20 can be 12 mm, so as to be easily put into the inside of the battery shell 2, and the overall length of the power generation element 10 and the energy storage element 20 should be slightly smaller than the height of the battery shell 2, for example, it can be 47-48 mm.

[0057] It should be understood that the head of the battery shell 2 can be the end close to the positive electrode of the battery, and the tail of the battery shell 2 can be the end close to the negative electrode of the battery, that is, when the battery is used to supply power to an electronic device, the current starts from the positive electrode (the head) of the battery, passes through the external circuit to the negative electrode (the tail) to form a closed loop.

[0058] Further, the energy storage element 20 can be an electronic element with an electric energy storage function, such as a capacitor, etc., capable of storing the electric energy generated by the power generation element 10 and supplying the external with power when the battery needs to discharge to the outside.

[0059] The self-power-generating battery comprises a battery shell provided with a knob at a tail portion, a power generation element and an energy storage element; the power generation element is arranged at one end of the battery shell close to the knob, the energy storage element is arranged at one end of the battery shell away from the knob, an input end of the power generation element is mechanically connected with the knob, an output end of the power generation element is electrically connected with an input end of the energy storage element, and an output end of the energy storage element is connected with a positive electrode of the battery; the power generation element is used for generating power supply electric energy when the knob rotates and transmitting the power supply electric energy to the energy storage element; and the energy storage element is used for storing the received power supply electric energy and outputting the stored electric energy to supply power to the outside in a battery discharging process. The power generation element is driven to generate power by rotating the knob, and the energy storage element is used to store the electric energy, so that the battery can independently supply power after being connected to an external circuit, and the battery can be timely supplemented after the battery power is used up in an outdoor or extreme situation where it is inconvenient to obtain battery supplement.

[0060] Reference Figure 2 and Figure 3 , Figure 2 it is a structural schematic view of the second embodiment of the self-power-generating battery of the utility model; Figure 3 it is a circuit connection diagram in the second embodiment of the self-power-generating battery of the utility model.

[0064] It should be understood that, due to the mechanical energy input by rotation, the mechanical energy converted by the power generation element 10 is not stable and has a large fluctuation within a certain range. By setting the π-type filter circuit comprising the first capacitor C1, the second capacitor C2 and the first inductor L1, the capacitor presents low impedance to high-frequency signals and thus can filter out high-frequency noise; and the inductor presents high impedance to low-frequency signals and thus can filter out low-frequency ripples, so as to ensure that the output DC voltage is more stable. The ground can be connected to the negative electrode of the battery, i.e. the connection mode of forming a complete electrical loop, and the specific grounding mode is not limited.

[0065] Further, the self-powered battery further comprises a discharging voltage stabilization circuit 302; an input end of the discharging voltage stabilization circuit 302 is electrically connected to an output end of the energy storage element 20; and a second end of the discharging voltage stabilization circuit 302 is connected to the positive electrode of the battery.

[0067] Taking a No. 5 battery as an example, the output voltage of the No. 5 battery is stabilized at 1.1-1.5V, and therefore the output voltage of the discharging voltage stabilization circuit 302 after voltage stabilization and filtering processing should be stabilized at 1.1-1.5V.

[0068] Further, the discharging voltage stabilization circuit 302 comprises a third capacitor C3, a fourth capacitor C4 and an LDO chip; a first end of the third capacitor C3 is connected to an output end of the energy storage element 20 and a first end of the LDO chip; a first end of the fourth capacitor C4 is connected to a second end of the LDO chip and the positive electrode of the battery; and second ends of the third capacitor C3 and the fourth capacitor C4 are grounded.

[0069] It should be noted that the LDO chip can be a low dropout linear regulator chip, and the LDO chip receives the output power of the energy storage element 20 and forms a stable voltage output power source with the third capacitor C3 and the fourth capacitor C4, for example, the power supply rejection ratio of the LDO chip can be adjusted to improve the ripple in the output voltage.

[0070] It should be understood that the charging voltage stabilizing circuit 301 and the discharging voltage stabilizing circuit 302 can be arranged on the same circuit board 30, and the circuit board 30 is arranged between the power generation element 10 and the energy storage element 20.

[0071] Further, referring to Figure 4 , Figure 4 It is a chip PCB design diagram in the second embodiment of the battery with power generation function. The ZCC5600 chip can also be used to replace the charging voltage stabilizing circuit and the discharging voltage stabilizing circuit to achieve similar charging and discharging output control functions, achieve higher integration and lower power consumption, and facilitate the setting of the chip PCB board to adapt to the structure of the cylindrical battery.

[0072] It should be noted that the ZCC5600 chip can be a lithium battery charging and discharging management special chip integrating a step-down converter, lithium battery charging management and battery charging state indication, and the charging current and charging voltage are adjustable. Integrated input overvoltage protection, input short circuit protection, output short circuit protection and over-temperature protection and other protection functions. Among them, the No. 3 pin of the ZCC5600 chip can be a discharging output pin connected with the energy storage element to ensure that the output voltage of the battery with power generation function is constant. The No. 5 pin of the ZCC5600 chip can be a charging output pin to ensure that the power generated by the power generation element in the battery with power generation function is transmitted to the energy storage element after stable voltage filtering.

[0073] The charging voltage stabilizing circuit including the first capacitor, the second capacitor and the first inductor is arranged, and the charging voltage stabilizing circuit is used for performing stable voltage filtering processing on the power generated by the power generation element, and transmitting the power after stable voltage filtering processing to the energy storage element, so that the power signal generated by the power generation element 10 is more stable when the knob is twisted. At the same time, the discharging voltage stabilizing circuit composed of the third capacitor, the fourth capacitor and the LDO chip is also arranged; the discharging voltage stabilizing circuit is used for performing stable voltage filtering processing on the power transmitted by the energy storage element, and transmitting the power after stable voltage filtering processing to the outside for power supply. The battery can continuously and stably output the voltage designed by the standard, ensure the stability of the battery use, and prolong the service life of the battery and the equipment,

[0076] It should be noted that the DC speed reducer motor can be composed of a DC motor and a gear reducer, and the output speed can be increased at a lower rotating speed by setting the gear ratio. The negative electrode can be connected to the motor shaft, and the motor shaft and the shell are completely not electrified, avoiding additional power loss.

Wherein, the diameter of the farad capacitor can be set to 12mm.

[0078] It should be noted that the farad capacitor can store energy through polarized electrolyte, but without chemical reaction, and the energy storage process is reversible, so it can be repeatedly charged and discharged hundreds of thousands of times. The nominal voltage is generally 2.7V, and the peak voltage is 3V, so the output voltage of the charging voltage stabilizing circuit 301 should be about 2.7V.

[0079] It should be understood that in addition to the farad capacitor, other chargeable devices can also be used instead, such as chargeable lithium batteries and other devices with energy storage and discharge functions.
