Example 1
According to a preferred embodiment of the present invention, referring to fig. 1 to 4, there is provided a noise reduction type emergency safety device for a flat tire of an automobile, characterized by comprising:
the belt body 1 is circumferentially arranged along the circumferential direction of the wheel rim 4; and
a connecting unit 2 for connecting the end of the band 1 and fixing the band 1 to a rim 4;
the belt body 1 comprises a thermoplastic elastomer and a steel plate arranged in the thermoplastic elastomer, a plurality of concave holes 11 are formed in the upper surface of the belt body 1, a silencing cavity 12 is formed in the lower surface of the belt body, the silencing cavity is provided with an opening facing a rim, and the opening is covered by the rim when the belt body is fixed on the rim.
Advantageously, the sound attenuation chamber 12 allows for efficient control of structural vibrations and noise. Preferably, the belt body 1 is provided with a tire pressure monitoring unit 3.
According to a further preferred embodiment of the present invention, the plurality of wells are a plurality of irregular wells.
According to a further preferred embodiment of the invention, the sound attenuation chamber is a concave chamber.
According to a further preferred embodiment of the invention, the sound attenuation chamber forms a labyrinth 14.
According to a further preferred embodiment of the present invention, the band body 1 is formed with upper and lower through holes 13 penetrating the steel plate. Preferably, the through holes are formed in the center of the belt body and are arranged at intervals in the longitudinal direction.
According to another preferred embodiment of the present invention, the upper and lower through holes 13 communicate with the concave holes 11 on the upper surface of the belt body 1 and the sound deadening chamber 12 on the lower surface.
According to a further preferred embodiment of the present invention, the plurality of concave holes form a pattern structure on the upper surface of the belt body 1.
According to a further preferred embodiment of the invention, the band body 1 is integrally cast.
According to a further preferred embodiment of the invention, the depth of the sound attenuation chamber is greater than the depth of the recess.
According to another preferred embodiment of the present invention, the depth of the sound deadening chamber is twice or more the depth of the concave hole. Preferably, the noise of the predetermined frequency band is eliminated by adjusting the shape and/or volume of the sound deadening chamber.
Preferably, the surface of the belt body is provided with a plurality of irregular concave holes, and a thermoplastic elastomer is adopted to be combined with the rim in a sealing way to form a plurality of cavities. And the labyrinth structure cavity communicated with the holes is formed through the through holes in an optimized mode.
Advantageously, according to the noise frequency bands formed by different wheels, the noise attenuation cavities with different shapes and volumes can be designed to eliminate the noise in the preset frequency bands.
More specifically, based on the tire cavity modal frequency problem, the overall vehicle noise, e.g., around 220Hz, can be optimized. This noise is typically due to the coupling of the tire acoustic cavity modal frequencies to the modal frequencies of surrounding structures, causing the noise to amplify on the transmission path, causing increased road noise in the cab. In order to solve the problem, the traditional optimization scheme is to adjust the modal frequency of the tire structural member, such as adding a vibration absorber to a rear axle, but the cost of the whole vehicle or the cost of a sample tool is increased.
Correspondingly, the principle of the invention is based on the noise optimization theory of the acoustic super structure, and a local resonance unit is periodically added on the traditional rim structure to construct a local resonance type acoustic metamaterial structure, so that low-frequency band gap characteristics can be generated, and the band gap characteristics can be utilized to realize effective control of structural vibration and noise.
Preferably, frequency fine tuning is optimized by changing the shape and length of the labyrinth for noise characteristics of different tires, improving the performance of the tire cavity mode problem. The problem of tire cavity mode is solved at the source of road noise problem, has great promotion to whole car cost of manufacture and development cycle.
The invention is based on a microporous structure sound absorption theoretical model, and can adjust the aperture and the spacing of the structural holes, and adjust the sound absorption frequency and the sound absorption numerical value. Meanwhile, the length and the space size of the maze can be adjusted according to the numerical value of the cavity modal frequency of the tire. The resonant cavity frequency formed by the cavities is coupled with the cavity frequency of the tire to form a local resonance unit, so that the purpose of resonance noise elimination is achieved, and road noise is reduced.
The invention can obtain one or more of the following technical effects:
the belt body consists of a thermoplastic elastomer and a steel plate arranged in the thermoplastic elastomer, and has a simple structure;
the belt body can be integrally cast and formed, so that the processing cost can be reduced;
the noise reduction cavity is attached to the outer peripheral surface of the rim, and can achieve the noise reduction function.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
