Abstract
The utility model discloses a portable power generator device which utilizes the vibration generated during the walking process of people to generate electricity; the power generator comprises a support body; a vibrative swing body, a transmission mechanism and a generator are arranged on the support body; the input end and the output end of the transmission mechanism are respectively in transmission connection with the swing body and a generator. The support body is arranged in the backpack; when the user walks, the swing body swings; the mechanical movements of the swing body are transferred to the generator through the transmission mechanism, enabling the rotary shaft to rotate to generate electricity. The portable power generator device generates electricity through the natural walking of people and has the advantages of safety, environmental protection, convenient portability, uneasy in limiting the generation process by the external conditions and being applicable to the fieldwork and the travelers.
Description
Technical field
The utility model relates to a kind of energy conversion, is specifically related to a kind of portable power generation device.
Background technique
Work in the open air, whilst on tour need carry small-power electrical equipment such as mobile phone, MP3, GPS usually, in order to guarantee this electric appliances sufficient electric power arranged, the way of normal employing is to carry a large amount of batteries.Number of batteries too much neither is easy to carry, and also is not easy to reclaim, as arbitrarily abandoning then serious environment pollution.Go back the portability solar power plant in addition, but this kind equipment is confined to the quality of weather conditions, when sunlight is inadequate, is difficult to produce electric energy.For these reasons, make urgent need develop a kind of environmental protection, be convenient for carrying and be not subject to the portable power generation device that ambient conditions restricts, use for the people who works in the open air, travels.
Knapsack is to be in the open-air requisite equipment of people.Once reported on " science " magazine: the back of the body has the people of knapsack can consume part energy to be used for the dipping and heaving shake of knapsack when walking: when knapsack was upwards shaken, the biological energy source of human body was converted into the potential energy of knapsack; When knapsack was shaken downwards, the potential energy of knapsack was absorbed by the body.According to above-mentioned principle, if the potential energy that knapsack falls partly can be transformed electric energy, just can directly utilize people's walking to generate electricity, so just can not influence generating because of the quality of natural condition.
The model utility content
The technical problem that the utility model solved is: the portable power generation device that the vibrations that provide a kind of people of utilization to walk to be produced are generated electricity.
The technological scheme that solves the problems of the technologies described above is: the portable power generation device, comprise support, and pendulum mass, driving mechanism and the generator that can shake are installed on the support, the input end of driving mechanism and output terminal are in transmission connection with pendulum mass and generator respectively
Further be, pendulum mass adopts sleeve, vertically is provided with guide rail on the support, and sleeve set also can slide up and down along guide rail on guide rail.
Further be that the two ends of sleeve are connected with support by spring respectively.
Further be, driving mechanism adopts rack-and-pinion, and the tooth bar in the rack-and-pinion is parallel with guide rail and be connected with sleeve, and gear and generator in the rack-and-pinion are in transmission connection.
The beneficial effects of the utility model are: support is installed in the knapsack, when people's pendulum mass swing when walking, makes the rotating shaft rotation of generator produce electric energy thereby the mechanical motion of pendulum mass reaches generator by driving mechanism.Portable power generation device of the present utility model produces electric energy by people's walking naturally, safety and environmental protection and easy to carry, and power generation process is not subject to the restriction of ambient conditions, people's use of especially suitable field work, travelling.
Description of drawings
Fig. 1 is the structural representation of the utility model portable power generation device.
Fig. 2 be among Fig. 1 A-A to sectional view.
The schematic representation of knapsack dipping and heaving shake when Fig. 3 behaves walking.
Be labeled as among the figure: support 1, spring 2, pendulum mass 3, sleeve 3a, tooth bar 4, spring 5, guide rail 6, gear 7, generator 8, knapsack 9.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Fig. 1, Fig. 2 and portable power generation device shown in Figure 3, comprise support 1, pendulum mass 3, driving mechanism and the generator 8 that can shake are installed on the support 1, the input end of driving mechanism and output terminal are in transmission connection with pendulum mass 3 and generator 8 respectively.This portable power generation device is installed in the knapsack 9, can produce vibrations when knapsack 9 moves with the person, and vibrations reach pendulum mass 3 and make pendulum mass 3 swings, makes the rotating shaft rotation of generator produce electric energy thereby the swing of pendulum mass 3 reaches generator by driving mechanism.
The swing mode of the structure of driving mechanism and pendulum mass 3 adapts, and pendulum mass 3 can adopt multiple swing mode, but since the people in the process of walking knapsack 9 mainly be to shake up and down, therefore in order to reach best electricity generation efficiency, pendulum mass 3 preferably adopts the mode that swings up and down.As a kind of concrete structure that pendulum mass 3 is swung up and down, pendulum mass 3 adopts sleeve 3a, vertically is provided with guide rail 6 on the support 1, and sleeve 3a is sleeved on the guide rail 6 and can slides up and down along guide rail 6.Like this, when knapsack 9 was shaken up and down, sleeve 3a can slide up and down in guide rail 6 by relative support 1, and drove the rotating shaft rotation that the driving mechanism motion finally makes generator 8.3a resets for the ease of sleeve, and the two ends of sleeve 3a are connected with support 1 by spring 2,5 respectively.
As Fig. 1 and Fig. 2, for being moved up and down, sleeve 3a is converted into the rotation of generator 8 rotating shafts,
Driving mechanism can adopt rack-and-pinion, and the tooth bar 4 in the rack-and-pinion and guide rail 6 are parallel and be connected with sleeve 3a, and the gear 7 in the rack-and-pinion is in transmission connection with generator 8.Fig. 2 middle gear 7 is by the rotating shaft transmitting torque of secondary driving gear to generator 8.In addition, driving mechanism also can adopt crankrocker mechanism, in order to pumping of sleeve 3a being converted into the rotation of bent axle, and then drives the rotation of generator 8 rotating shafts.
As Fig. 3, utilize this portable power generation device, suppose height be 175cm, when standing hip apart from ground about 80cm, stride 60cm, the frequency f of taking a step be the people of 1.5 step/s when heavy burden 10kg normally walks, then the upper and lower displacement Δ L of knapsack 9 centers of gravity is about 5.8cm.If loss in the middle of ignoring, generated output is P=m*g* Δ L*f=10*9.8*0.058*1.5=8.526W.Suppose conversion ratio η=50%, the output power of then generating electricity P1=P* η=8.526*0.5=4.263W.And under the charging voltage of regular handset battery, (be generally 4.2V), and the electric current of about 1A can be provided, can be two battery charge simultaneously, perhaps be the common No. 5 Ni-MH batteries chargings of 10 joints simultaneously, charging ability is no less than common charger.
