Description
More particularly, the present invention relates to a tire including a contact electrification power generation module having a plurality of external electrodes, more particularly, to a method of generating electricity by charging static electricity generated in a sound absorbing material of a tire and a tire, The present invention relates to a tire including a contact charging self-generating module having a plurality of external electrodes that can be operated.
BACKGROUND ART [0002] In recent years, researches have been actively conducted on devices for generating electricity in tires.
For example, recently, research and development of a piezoelectric power generation system using the force that a tire is pressed by a ground when a tire moves has been performed.
However, when a piezoelectric power generation system is applied to a tire, a piezoelectric power generation system is very expensive, and the lifetime of the piezoelectric material is short, which makes it difficult to use it permanently.
More specifically, the method of generating electricity by using the pressure or the force applied to the sensor is referred to as a piezo generation method. Such a piezoelectric power generation method has a lower efficiency than a static power generation method and requires a circuit for amplification using an OP-AMP, which complicates the structure and makes it impossible to permanently use the piezoelectric element.
In recent years, a technique has been developed for performing power generation using heat generated due to friction between a tire and a ground during vehicle operation.
However, the technique of performing power generation using the heat generated by the friction between the tire and the ground has a problem in that it is not effective in an environment in which the frictional heat of the tire is not sufficiently generated due to the influence of weather or the like.
Accordingly, there is a need for a tire that includes a self-generating module that can perform power generation more efficiently and economically.
An object of the present invention to solve the above problems is to provide a contact charger having a plurality of external electrodes capable of generating electricity by charging static electricity generated inside a tire and a sound absorbing material of a tire, And a tire including the power generation module.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise form disclosed. There will be.
According to an aspect of the present invention, there is provided a sound absorbing device comprising: a sound absorbing material provided on an inner side of an inner liner of a tire; An internal electrode part provided inside the sound absorbing material and extending in the longitudinal direction of the sound absorbing material; And an outer electrode portion spaced apart from the sound-absorbing material and provided between the sound-absorbing material and the inner liner, the outer electrode portion having a plurality of second outer electrodes bonded to an inner surface of the inner liner, wherein the sound- Wherein the inner electrode portion and the outer electrode portion are charged to generate electricity. The present invention also provides a contactless electric power generating module including a plurality of external electrodes.
According to an embodiment of the present invention, a receiving hole corresponding to the shape of the second external electrode may be formed at a lower portion of the sound absorbing member.
In the embodiment of the present invention, the receiving hole may be formed such that when the sound absorbing material is bonded to the inner surface of the inner liner, the second external electrode is inserted.
In an embodiment of the present invention, it may further comprise a case for housing the sound absorbing material, the internal electrode portion, and the external electrode portion therein.
In an exemplary embodiment of the present invention, the power supply unit may further include a power supply unit connected to the internal electrode unit and the external electrode unit to generate electricity.
In the embodiment of the present invention, the power supply unit may include an air pressure sensor for measuring the air pressure of the tire; And a power source element converting the non-sinusoidal or sinusoidal electric power generated in the internal electrode unit and the external electrode unit into a DC current and providing the same to the air pressure sensor, And the like.
According to an aspect of the present invention, there is provided a vehicle equipped with a tire including a contactless electric power generating module having a plurality of external electrodes.
The effect of the present invention with the above-described structure is that the self-power generation module using static electricity is provided inside the tire, so that electricity can be efficiently generated. In addition, since the present invention can use the generated electricity to operate the air pressure sensor, a separate external power source for operating the air pressure sensor is unnecessary, which is economical.
The sound absorbing material of the tire is made of a material such as polyurethane which generates a lot of static electricity. Therefore, as in the present invention, when the internal electrode portion is provided in the sound absorbing material, electricity can be generated more efficiently.
In addition, since the present invention performs power generation by using static electricity generated in a tire, static electricity generated in the tire and in the vehicle can be effectively removed.
In addition, since the present invention generates electricity by using a sound absorbing material, it has a larger generating area, higher generating capacity, and uniform power generation than the conventional piezo generating method.
Further, since the self-power generating module of the present invention is formed as a one-piece structure connected to the sound absorbing material, the noise absorbing function of the conventional sound absorbing material tire can be maintained.
It should be understood that the effects of the present invention are not limited to the above effects and include all effects that can be deduced from the detailed description of the present invention or the configuration of the invention described in the claims.
