At present, a photoelectric device installed at the position of an automobile hub basically needs to provide a battery or utilize a coil to cut magnetic induction line movement to provide electric energy for the photoelectric device. Because the hub is provided with the battery, the battery has explosion risk, and the battery needs to be replaced, which is very inconvenient. And utilize the coil cutting magnetic induction line electricity generation, need change the original part of automobile wheel hub and just can realize, some repacking probably still are illegal, can produce the noise moreover, are unfavorable for falling of car and fall the noise. A new power supply path is needed to supply power to the photovoltaic device.
The invention provides a power generation device aiming at solving the technical problem and providing a new way for supplying electric energy to a photoelectric device on an automobile hub.
The specific structure of the power generating apparatus of the present invention will be described below in specific embodiments:
as shown in fig. 1 and 2, in an embodiment of the present invention, the power generation device 100 includes a mount 10 and a piezoelectric module 30, the mount 10 being configured to be mounted to a hub 200 of a wheel. The piezoelectric module 30 is mounted on the mount 10, and the piezoelectric module 30 is used to output electric power. When the wheel drives the piezoelectric module 30 to make circular motion on a vertical plane, the pressure applied to the piezoelectric module 30 changes to generate electric energy.
Referring to fig. 2, fig. 2 is a force analysis diagram of the piezoelectric module 30, F-direction-centripetal force, G-gravity of the piezoelectric module 30, m-mass of the piezoelectric module 30, G-G is gravitational acceleration, V-linear velocity.
It can be understood that, according to the technical solution of the present embodiment, under the action of gravity and centripetal force, the piezoelectric module 30 is subjected to a pressure change applied by the mounting member 10, that is, a supporting force applied by the mounting member 10 to support the piezoelectric module 30 is changed to generate electric energy, so as to provide the electric energy. Specifically, when the piezoelectric module 30 is located above the center of the hub 200, the gravity and the centripetal force of the piezoelectric module 30 are opposite, and when the piezoelectric module 30 is located below the center of the hub 200, the gravity and the centripetal force of the piezoelectric module 30 are in the same direction, so that when the wheel drives the piezoelectric module 30 to perform circular motion, the piezoelectric module 30 is subjected to a resultant force, i.e., a pressure, which is changed by the mounting member 10, so that the piezoelectric module 30 generates electric energy to be supplied to the photoelectric device on the hub 200. This mode is because there is not relative motion between installed part 10, piezoelectric module 30 and the wheel hub 200, can avoid producing the noise for the wheel hub 200 motion to can reduce the noise of wheel, and then can reduce the noise of car, promote and drive experience. Utilize piezoelectric module 30 to produce the electric energy under the effect of gravity and/or centripetal force, piezoelectric module 30 directly installs on wheel hub 200 through installed part 10, need not repack wheel hub 200, safe and reliable, and effective for a long time, convenient to use, the energy saving.
In the actual process of automobile movement, when the wheel moves at a constant speed, the piezoelectric module 30 moves along the circumference on the vertical plane, the piezoelectric module 30 is located at any position on the circumference, the centripetal force applied to the piezoelectric module 30 is equal, the direction of gravity is always vertical downward, and when the piezoelectric module 30 moves circumferentially, the position changes and the piezoelectric module is overturned, so that as for the pressure receiving surface of the piezoelectric module 30, the pressure receiving surface is converted into the pressure applied to the pressure receiving surface by the gravity of the piezoelectric module 30 or the external gravity, the pressure changes in the direction, and the pressure is changed, so that conditions are provided for generating electric energy. When the wheel does non-uniform motion, the piezoelectric module 30 is subjected to a varying centripetal force, and thus is subjected to a varying pressure of the mounting member 10 against the piezoelectric module 30, thereby providing conditions for generating electric energy. Or, when the wheel does non-uniform motion, the piezoelectric module 30 is subject to a varying centripetal force and a varying gravity with respect to the direction of the piezoelectric module 30, so that the piezoelectric module 30 is subject to a varying resultant force, thereby providing a condition for generating electric energy.
Specifically, the piezoelectric module 30 may be free-standing, generating only electric power, connected to other electrical devices through wires; the piezoelectric module 30 may also be an integrated type, and includes a capacitor, a circuit, a piezoelectric ceramic plate 31, etc., where the piezoelectric ceramic plate 31 generates electric energy when subjected to a varying pressure, the piezoelectric ceramic plate 31 is connected to the capacitor through the circuit, the capacitor may store electric charges generated by the piezoelectric module 30, and the capacitor is connected to an electric appliance, such as a hub light, etc., through another circuit. Since the principle of generating electric energy by the piezoelectric module 30 under a varying pressure is the prior art, it is not described herein again.
It should be noted that, in addition to the embodiments described below, the hub 200 for mounting the mounting member 10 to the wheel may also adopt other effective and reasonable manners, for example, the mounting member 10 is provided with a fixing fastener, and is fixed on a spoke of the hub 200 through the fixing fastener, so that the wheel drives the piezoelectric module 30 mounted on the mounting member 10 to make a circular motion; for another example, the mounting member 10 is formed as a hub cover, and is fixedly mounted to a side surface of the hub 200 by bolts.
The number of the piezoelectric modules 30 may be 1, 2, 3, 4, 5, 6, etc., and the number of the piezoelectric modules 30 is not limited herein and may be set according to the power supply requirement. When a plurality of piezoelectric modules 30 are provided, the piezoelectric modules 30 may be connected in parallel or in series, and the plurality of piezoelectric modules 30 may be arranged at intervals, stacked to enhance the pressure effect, or arranged in other manners.
The piezoelectric module 30 and the mounting member 10 may be installed at an outer side of the hub 200 for easy installation and maintenance; or may be installed at the inner side of the boss 200 to protect the piezoelectric module 30 and the mount 10; or between the tyre and the hub 200; other possible locations are also possible.

It can be understood that the counterweight 33 is pressed against the piezoelectric ceramic plate 31, and the counterweight 33 is located on a side surface of the piezoelectric ceramic facing the middle of the hub 200, that is, the counterweight 33 is located on a side surface of the piezoelectric ceramic facing the rotation central axis of the hub 200, so that during the circular motion of the counterweight 33 and the piezoelectric ceramic plate 31, the pressure of the counterweight 33 pressing the piezoelectric ceramic plate 31 is changed under the action of the gravity force changing in the opposite direction and/or the changing centripetal force, so as to enable the piezoelectric ceramic plate to generate electric energy.
Specifically, the piezoelectric module 30 is fixedly connected to the mounting member 10 by screws, adhesives, welding, or the like. The counterweight 33 is fixedly connected with the piezoelectric ceramic piece 31 in a manner of screw connection, gluing, welding and the like.
