Background

Since the industrial revolution, various modern vehicles are gradually integrated into the lives of people, so that the lives of people are more convenient and quicker. In the transportation, automobiles are mainly used, and with the progress and vigorous development of science and technology, the functions of automobiles are not limited to simple transportation, and even have auxiliary functions such as air conditioning, audio, television equipment, satellite navigation, and the like, so that the power of automobiles must be converted into electric energy for various in-vehicle facilities in addition to driving wheels.

Referring to fig. 1, a simple structure diagram of a "four-wheel drive" vehicle is shown, in which a driving module 11 (such as a motor and an engine), an electric module 12 (such as a generator, a storage battery and a control circuit thereof) and a transmission module 13 (such as a transmission case, a transmission shaft 131 and a differential 132) are disposed inside the vehicle 1, wherein the driving module 11 is respectively connected to the electric module 12 and the transmission module 13, when the driving module 11 is in operation, the driving module 11 can generate kinetic energy, and rotate a wheel axle 15 of a wheel 14 through the transmission module 13, so that the wheel 14 can drive the vehicle 1 to move forward, and in addition, the kinetic energy generated by the driving module 11 can further drive the electric module 12 to generate and store electric energy, and the generated electric energy can be used for starting the vehicle 1, providing in-vehicle equipment, lighting lamps and the like.

The device for storing electric energy in the electric power module 12 is a "battery", when a user starts an automobile, the battery must instantly provide a large current to the starting motor in the driving module 11 to start the engine, after the engine is started smoothly, the generator in the electric power module 12 can be driven to supply the electric quantity required by other devices in the automobile, and when the electric power provided by the generator is higher than the electric quantity required by the devices in the automobile, the redundant electric energy can be stored in the battery. However, as the functions of the in-vehicle devices are more and more diversified, the required electric power is higher, and 20 years ago, the power of the generator of a general medium-sized vehicle is about 500 w, and nowadays, the power is increased to about 1000 w, and the power consumption of the vehicle is seen to have a trend of increasing. Since the increase of power consumption also means that the vehicle must consume more fuel (to drive the generator) and emit more greenhouse gases, which is very serious for environmental ecology, nowadays, large enterprises and governments all over the world put great efforts on using alternative energy as the power source of the vehicle.

Although the hybrid vehicle and the electric vehicle have been designed by the manufacturers, they are still difficult to be popularized due to the production cost and the arrangement of the charging equipment. Considering that no matter traditional automobiles, hybrid electric vehicles and electric vehicles, all the equipment of the automobiles need to be started by 'electric energy', the inventor thinks and researches whether the traditional automobiles, hybrid electric vehicles and electric vehicles can be used for generating electric energy actively or not in the direction of 'actively generating electric energy', and actively utilizes the kinetic energy of the automobiles during running to generate electric energy so as to improve the efficiency of utilizing the energy of the automobiles and actively generate energy which is consumed by the automobiles during running so as to achieve two effects of 'generating electricity' and 'saving energy'. Therefore, how to design a device that can be conveniently installed on the existing car structure and generate electric energy by using the kinetic energy of the car during operation is an important issue to be solved in the present invention.

Detailed Description

The invention relates to a clutch type power generation device applied to wheel axles, please refer to fig. 2 and fig. 3, which show a first preferred embodiment of the invention, the clutch type power generation device 3 is installed on an automobile, the automobile is provided with a driving module, an electric module and a transmission module (the automobile is configured as shown in fig. 1, but not limited to the automobile with four-wheel drive, the invention can be applied to the automobile with relative motion mechanism between the wheel axles), the driving module is respectively connected with the electric module and the transmission module, and the transmission module can be respectively connected to the wheels 22 of the automobile through a plurality of wheel axles 21, under the condition that the driving module is started to operate, the kinetic energy generated by the driving module can sequentially drive the wheel axles 21 and the wheels 22 to rotate through the transmission module.

The clutch type power generation device 3 comprises a shell 31, a stator base 32, a rotor base 33 and a clutch mechanism 4; the outer edge of the housing 31 is locked to a suspension device 23 of the vehicle (which may also be fixed to a vehicle chassis, or fixed between a half shaft and a chassis of a "four-wheel drive" vehicle), and an accommodating space is provided therein, and a through hole is respectively formed at front and rear ends of the accommodating space (for convenience of description, it is assumed that the right side of fig. 2 is a "front end" and the left side of fig. 2 is a "rear end"), so that the wheel axle 21 can penetrate through the housing 31 through the through hole and rotate relative to the housing 31; the accommodating space is used for accommodating the stator seat 32, the rotor seat 33 and the clutch mechanism 4, wherein the stator seat 32 is fixed to the inner edge of the housing 31, the stator seat 32 includes a plurality of stators 321 (e.g., coils), and the stators 321 are arranged along the circumferential direction of the wheel axle 21 and electrically connected to an electric power module in the vehicle.

Referring to fig. 2-3, the rotor base 33 is movably sleeved on the outer edge of the axle 21 through the bearing 24 to be positioned between the stator base 32 and the axle 21, the rotor base 33 includes a plurality of rotors 331 (e.g., field magnets), the rotors 331 are also arranged along the circumferential direction of the axle 21, respectively correspond to the stators 321, and maintain a predetermined gap with the stators 321 (as shown in fig. 3, the arrangement of the stators 321 and the rotors 331 is schematically illustrated, and for highlighting the structural emphasis, only the housing 31, the stators 321, the rotors 331 and the like are drawn in fig. 3).

Referring to fig. 2-5, the clutch mechanism 4 is disposed in the housing 31 adjacent to the wheel 22 (in the embodiment, the clutch mechanism 4 is embedded in a through hole at one end of the housing 31), and includes a driven ring 41, a rotating disc 42, a plurality of connecting rods 43, a plurality of driving blocks 44, and a plurality of elastic elements 45; wherein, one side of the passive ring 41 is coaxially fixed to one side of the rotor seat 33, so that the passive ring 41 and the rotor seat 33 can both rotate relative to the wheel axle 21 with the wheel axle 21 as the axis, and the inner edge of the passive ring is circumferentially provided with a plurality of first embedding parts 411.

Referring to fig. 2 and 5, the rotating disc 42 is positioned in a hollow portion of the driven ring 41, a through hole 421 is formed in the center thereof, and an engaging groove 422 is formed in the through hole 421, so that the axle 21 can pass through the through hole 421 and engage with the engaging groove 422 (e.g., a protrusion is formed on the axle 21 corresponding to the engaging groove 422) to drive the rotating disc 42 to rotate synchronously; one end of each link 43 is pivotally connected to the rotating disc 42; the middle section of each driving block 44 is pivotally connected to the other end of the corresponding connecting rod 43 so as to be capable of moving between the outer edge of the rotating disc 42 and the inner edge of the passive ring 41, and a second engaging portion 441 is disposed on each driving block 44 corresponding to the first engaging portion 411.

One end of each elastic element 45 is connected to the rotating disc 42, and the other end thereof is connected to each corresponding driving block 44, so as to apply an elastic force to each driving block 44, wherein the elastic force makes one side of each driving block 44, which is opposite to the second clamping portion 441, abut against the outer edge of the rotating disc 42, so that a predetermined distance is kept between each first clamping portion 411 and each second clamping portion 441, that is, the rotating disc 42, the driving blocks 44 and the driven ring 41 are not connected with each other.

Thus, when the rotating disc 42 is driven by the axle 21 to rotate synchronously but the rotation speed (i.e. the rotation speed of the axle 21 or the tire) is not enough to generate a sufficient centrifugal force on each driving block 44 to overcome the elastic force, the driven ring 41 and the rotor base 33 cannot rotate along with the axle 21 (as shown in fig. 5) because each first engaging portion 411 does not engage with the corresponding second engaging portion 441, i.e. the driving kinetic energy generated by the vehicle does not need to push the rotor base 33 at the same time.

On the contrary, referring to fig. 2, 4 and 6, when the rotation speed of the rotating disc 42 (i.e. the rotation speed of the wheel axle 21 or the tire) is sufficient to generate a centrifugal force on each driving block 44 to overcome the elastic force, the outer edge of each driving block 44 is abutted to the inner edge of the driven ring 41 outwards due to the centrifugal force, so that each second engaging portion 441 is engaged with each corresponding first engaging portion 411, respectively, so that the driven ring 41 and the rotor base 33 can rotate along with the wheel axle 21 (as shown in fig. 6), and at this time, each rotor 331 on the rotor base 33 rotates around the wheel axle 21 and generates a time-varying magnetic field, thereby generating an induced electrical energy on the stator 321 and storing the induced electrical energy in the power module.

Since the rotation speed of the rotating disc 42 must be greater than a predetermined value, a centrifugal force of sufficient magnitude is generated to engage the first and second engaging portions 411, 441 with each other, and further to drive the rotor 331 to generate induced electric energy, so that, when the vehicle is just started and the vehicle speed does not reach a predetermined vehicle speed, the driving block 44 will be limited at the outer edge of the rotating disc 42 by the elastic force of the elastic element 45, so that the second engaging portion 441 on the driving block 44 will not engage with the corresponding first engaging portion 411, so as to ensure that the weak kinetic energy generated when the vehicle is just started will not be consumed to drive the clutch type power generation apparatus 3, thereby avoiding the problem of excessive load and energy consumption.

When the rotation speed of the rotating disc 42 is greater than the predetermined value, since the vehicle is already in a state of low speed stepping into middle speed forward, and has inertia and momentum with a certain value, the wheel axle 21 can drive the passive ring 41 and the rotor seat 33 smoothly, so that the problem that the torque force and torque force generated by the static friction force of the clutch mechanism 4 are required when the vehicle is just started can be effectively avoided, and the problem that the electric power module of the vehicle must output a larger current to start the engine in the driving module can be solved (under the condition that the torque force and torque force are too large).

It should be noted that, in the foregoing embodiment, the clutch type power generating device 3 is installed on a "four-wheel drive" vehicle, that is, the wheel axle 21 belongs to a "driving wheel axle" in the vehicle, and can receive the kinetic energy transmitted from the driving module directly through the transmission module, however, the invention can also be applied to other types of vehicles, for example: the clutch type power generation device 3 can be arranged on a driven wheel shaft of a two-wheel drive automobile, and when the automobile moves forward, kinetic energy is transmitted to the wheel shaft by wheels, so that power generation can be still carried out by the same principle, and power required by equipment in the automobile is provided, and further, the consumption of fuel is reduced. Similarly, the invention can also be used on various automobiles driven by alternative energy sources, such as electric vehicles, oil-electric hybrid vehicles and the like, so as to improve the energy utilization efficiency of the vehicles of the type, reduce the configuration quantity and cost of batteries, improve the mileage of the vehicles during single charging, greatly reduce the charging frequency and prolong the service life of the batteries.

Because the clutch type generating device 3 of the invention utilizes the kinetic energy generated when the wheel shaft 21 rotates at high speed to generate electricity, the clutch type generating device can be easily installed on various existing automobiles without greatly changing the existing structure of the automobile, and in addition, the clutch type generating device 3 can be respectively installed on a plurality of wheel shafts 21 (no matter driving wheel shafts or driven wheel shafts) of the automobile, so as to generate electricity through a plurality of clutch type generating devices 3, thereby effectively improving the generating speed and the generating capacity.

Referring to fig. 2 and 3 again, in the foregoing embodiment, the clutch type power generating device 3 is packaged as a single component to be directly locked to the suspension device 23 and to be passed by the axle 21, so that the stator seat 32, the rotor seat 33, etc. are configured as a hollow circular body (as shown in fig. 3). In order to improve the assembling convenience of the clutch type power generator 3, the manufacturer can also change the configurations of the housing 31, the stator seat 32, and the rotor seat 33, for example: the manufacturer can disassemble the housing 31 into an upper housing and a lower housing, and design the stator seat 32 into two semicircular components respectively disposed in the upper housing and the lower housing, so that the stator seat can be mounted on the axle 21 in a manner of upper and lower embedding and locking, and upper and lower assembling.

As shown in fig. 5, in order to make the driving blocks 44 stably driven by the rotating disc 42, the configuration of the rotating disc 42 can be designed to be polygonal (triangular in the present embodiment), and each driving block 44 respectively abuts against one edge of the rotating disc 42, so that when the rotating disc 42 rotates, the outer edge thereof can reliably abut against and push the driving block 44, so as to improve the operation stability of the clutch type power generation apparatus 3.

The above description is only a few preferred embodiments of the present invention, and the technical features of the present invention are not limited thereto, and those skilled in the art can easily conceive equivalent changes without departing from the protection scope of the present invention after considering the technical content of the present invention.
