Technical Field

The invention relates to the field of renewable energy sources, in particular to an amplitude-adjustable backpack load power generation device for collecting mechanical energy of human body load movement and converting the mechanical energy into usable electric energy.

Background

In modern life, although traffic technology has been developed to a great extent, carrying a backpack to carry a load and walking is still a necessary activity, such as carrying survivors to carry the survivors far enough in the field, carrying weapons and electronic equipment to march by soldiers. The function of the backpack is also changed from being single to multiple, and many electronic devices are added to provide functions of positioning, lighting and the like. Meanwhile, a plurality of human body kinetic energy capturers are proposed, and the human body kinetic energy is collected and converted into electric energy for electronic equipment. However, the use of the human body kinetic energy capturing device requires additional expenditure of biological energy by the human body, which may amplify the biological energy consumption when the range of limb movement is large or the movement conditions are limited, and the power generation efficiency is also affected. Under different road conditions and different walking speeds and load bearing qualities, the requirements on electric energy and the bearing degree of the additional expenditure on the biological energy are different. Therefore, a new method is needed to be found, which can collect kinetic energy from the backpack for human weight walking to generate power and can adjust the vibration amplitude according to different environmental conditions and human body states to meet different requirements. According to the search result, the method similar to the present application or the power generation device in the backpack is not used for capturing the kinetic energy of walking with human load and adjusting the amplitude as the power supply of the electronic device at present.

Disclosure of Invention

In order to solve the problems, the application provides the backpack load-bearing power generation device with the adjustable amplitude, the device can be easily loaded on a backpack or unloaded from the backpack, the minimum damage to the common original backpack is ensured, and effective electric energy is effectively provided for electronic equipment. The resistance value of the adjustable resistor in the amplitude adjusting box which is conducted with the output end of the generating set through a wire is adjusted, so that the electric damping generated by the generator is changed, the vibration amplitude of the backpack is manually adjusted, and the comfort of the human body in movement under different working conditions is guaranteed.

An amplitude-adjustable backpack load-bearing power generation device comprises a tubular power generation prototype device and an amplitude adjusting box; the tubular power generation prototype device is directly connected to the U-shaped support frame of the original backpack through the buckle. Two rows of steel wire ropes extending out of the tubular power generation prototype device penetrate through the woven cloth on the back of the backpack and are connected with the original straps of the backpack. When the human body walks or runs, the mass center of the human body regularly swings up and down relative to the ground in the vertical direction to form a certain amplitude. When the steel wire rope of the tubular power generation prototype device in the backpack is connected to the shoulders of a human body through the straps, the steel wire rope can be dragged along with the up-and-down swinging of the mass center of the human body, so that the kinetic energy of the human body is utilized, and the kinetic energy is converted into electric energy through the rotation of the generator in the tubular power generation prototype device. The input port of the amplitude adjusting box is connected with the output port of the power generation device through a lead, and the adjustable resistor inside the amplitude adjusting box can be manually adjusted through a knob. When the adjustable resistance is increased, the electric damping is reduced, the electric damping force of the tubular power generation prototype device for resisting the movement of the steel wire rope is reduced, and therefore the amplitude of the backpack is increased. In this case, the instantaneous power generation power rises, and the additional consumption of bioenergy by the human body rises; when the adjustable resistance is reduced, the electric damping is increased, the electric damping force of the tubular power generation prototype device for resisting the movement of the steel wire rope is increased, and therefore the amplitude of the backpack is reduced. In this case, the instantaneous generated power decreases, and the additional biological energy consumed by the human body also decreases. When the backpack is used for straight running on a normal flat road, the influence of the backpack vibration on human limbs is relatively small due to the walking rule of the human body, so that the electric power output can be increased, and a small amount of extra biological energy consumption is paid; on rugged mountain roads, due to the complex environment, the human body can consume more bioenergy than usual, and the vibration of the backpack can also cause negative effects on the limbs of the human body, so that the electric power output can be reduced at the moment, and the stable and minimum bioenergy output of the human body is ensured.

The U-shaped support frame is provided with two rows of hole sites for positioning the tubular power generation prototype device, the tubular power generation prototype device is fixed at different height positions inside the backpack according to the individual height and the requirement of a wearer, the comfort of wearing the backpack is guaranteed, and the capacity of adapting the shape and the size of a load weight is realized.

The tubular power generation prototype device comprises two groups of power generation devices which are symmetrically arranged, wherein each power generation device comprises a power generator for generating power, a reduction gearbox, a transmission shaft and a volute spiral spring; one end of the reduction gearbox is connected with an input shaft of the generator, and the other end of the gearbox is connected with an output end of the transmission shaft, so that the rotating speed of the generator is increased, and the generating power is effectively increased. The transmission shaft is wound by one end of the steel wire rope and is used for transmitting power generated by pulling the strap and converting the linear motion of the steel wire rope into the rotary motion available for the generator. The inner wall of the spiral spring is connected with the transmission shaft, and the outer wall of the spiral spring is connected with the shell of the power generation prototype device and used for keeping the steel wire rope tight and keeping the generator to rotate reversely. When the steel wire rope drives the transmission shaft to rotate in the positive direction, the inner wall of the volute spiral spring rotates to generate elastic potential energy; after the steel wire rope is stretched, the spiral spring releases elastic potential energy to drive the transmission shaft to rotate reversely, so that the power generation device returns to the initial position, and the periodic work of the whole device relative to a human body is maintained.

The shell of the power generation prototype device is made of an aluminum alloy material and is treated by sand blasting and anodic oxidation processes. The surface of the workpiece shell subjected to the sand blasting process obtains certain cleanliness and different roughness, the mechanical property is improved, and the fatigue resistance is improved; the workpiece shell after the anodic oxidation process can be colored, so that the corrosion resistance is improved, the wear resistance and the hardness are enhanced, and the metal surface is protected.

The amplitude adjusting box consists of an internal adjustable resistor, an external adjusting knob and a rectifying voltage-adjusting circuit. The external adjusting knob is provided with a resistance reading which corresponds to the output electric power and can be manually rotated and adjusted. The alternating current passing through the adjustable resistor becomes direct current with stable output voltage after passing through the rectification voltage-regulating circuit, and can be directly stored in a storage battery to supply power for portable electronic equipment.

When the backpack is used for straight running on a normal flat road, the influence of the backpack vibration on human limbs is relatively small due to the walking rule of the human body, the resistance value of the adjustable resistor is increased, the electric power output is increased, and a small amount of extra biological energy consumption is paid; on rugged mountain roads, due to the complex environment, the human body can consume more bioenergy than usual, the vibration of the backpack can also cause negative effects on the limbs of the human body, the resistance value of the adjustable resistor is reduced at the moment, the electric power output is reduced, and the stable and minimum bioenergy output of the human body is ensured.

Detailed Description

The present invention will be further described with reference to the following examples, but is not limited thereto.

Fig. 1 shows an amplitude-adjustable backpack load-bearing power generation device according to the present invention. The tubular power generation prototype device is fixedly connected to a U-shaped support frame 4 of the backpack through a buckle 1. Two rows of hole sites for positioning the power generation device are arranged on the U-shaped support frame 4, and the U-shaped support frame can be fixed at different height positions in the backpack according to the individual height and requirements of a wearer. One end of the steel wire rope 2 is wound and connected on the transmission shaft 7 shown in figure 2, and the other end is connected on the backpack strap 9 shown in figure 3, and is used for transmitting effective displacement and force generated by pulling the strap by swinging the mass center of the human body up and down. The transmission shaft 7 converts the linear displacement into the rotational displacement, and further rotates the generator 8 to generate electric energy. The inner wall of the volute spiral spring 6 is connected with the transmission shaft 7, and the outer wall of the volute spiral spring is connected with the shell 3 of the power generation prototype device and used for keeping the steel wire rope tight and keeping the generator to rotate reversely. When the transmission shaft 7 is positively rotated by the tensile force of the steel wire rope 2, the inner wall of the spiral spring 6 is correspondingly rotated, and the outer wall is not rotated, so that elastic potential energy is stored. When the steel wire rope 2 is stretched, the spiral spring 6 releases elastic potential energy to drive the transmission shaft 7 to rotate reversely, so that the power generation device returns to the initial position, and the periodic work of the whole device relative to a human body is maintained.

The human body bears the power generation device under different conditions, so that the power generation requirement and the vibration bearing degree are different, and the power generation power needs to be increased by increasing the vibration amplitude when the human body runs straight on a flat road; in rough mountain roads, the amplitude needs to be reduced to save the consumption of biological energy and improve the stability of limbs. The input port of the amplitude adjusting box 5 is connected with the output port of the generator 8 through a lead, and the adjustable resistor inside the amplitude adjusting box 5 can be manually adjusted through a knob. When the adjustable resistance is increased, the electric damping is reduced, the electric damping force of the power generation device for blocking the movement of the steel wire rope is reduced, and therefore the amplitude of the backpack is increased. In this case, the instantaneous power generation power rises, and the additional consumption of bioenergy by the human body rises; when the adjustable resistance is reduced, the electric damping is increased, the electric damping force of the power generation device for blocking the movement of the steel wire rope is increased, and therefore the amplitude of the backpack is reduced. In this case, the instantaneous generated power decreases, and the additional biological energy consumed by the human body also decreases. The amplitude adjusting box 5 is arranged on the lateral side of the fabric 10 on the outer surface of the backpack after being installed, and a carrier can conveniently adjust in real time. The steel cable 2 extends through a hole in the back of the fabric 10 on the outer surface of the backpack, and the structure of the backpack is damaged to the minimum extent. The device can be easily loaded on or unloaded from the backpack, ensures the minimum modification damage to the common original backpack, and effectively provides effective electric energy for electronic equipment.
