Description

Technical Field

[0001] The utility model relates to the technical field of automobile wheel cover sound insulation cotton, in particular to an automobile wheel cover sound insulation cotton. Background Art

[0002] A car wheel cover is a decorative or functional accessory installed on the wheel, also known as a rim cover or wheel cover, which can improve the appearance of the vehicle and make it look neater, more stylish and attractive. There is usually sound insulation cotton inside the wheel cover to isolate or eliminate the noise generated by the wheel. The sound insulation mechanism of the sound insulation cotton is that there are a large number of tiny interconnected pores inside the material. Sound waves can enter the material along these pores and rub against the material to convert sound energy into heat energy. Unlike sound-absorbing materials, sound insulation cotton weakens the projected sound energy and blocks the propagation of sound.

[0003] In the wheel cover, the sound insulation cotton can only block the noise during use, but cannot absorb and process the noise. Secondly, since the wheel rotates at high speed during operation, there is a large centrifugal effect on the sound insulation cotton installed inside, and the sound insulation cotton is prone to deformation or falling off. Finally, when the sound insulation cotton is fixed, there is a lack of clamping plates, and the sound insulation cotton cannot be well clamped between the plates. Therefore, a car wheel cover sound insulation cotton is proposed to address the above problems. Summary of the invention

[0004] The utility model aims to provide a car wheel cover sound insulation cotton to solve the problems raised in the above background technology.

[0026] A positioning hole 4 penetrating the PET cotton 2 is provided on one side of the PET cotton 2, and a positioning hole 4 penetrating the Thinsulate sound-absorbing cotton 3 is provided on one side of the Thinsulate sound-absorbing cotton 3; there are five positioning columns 8, which are arranged in an "I" shape on one side of the fixing frame 6; the diameter of the damping ring 14 is smaller than the diameter of the fixing groove 11, and the damping ring 14 and the fixing groove 11 are slidably connected; the end of the push rod 15 away from the sliding plate 13 is hemispherical, and its diameter is smaller than the diameter of the hemispherical positioning groove 7.

[0027] Working process: This device is used in the wheel cover of the car. Through its own function, it blocks or isolates the noise on the outside of the car wheel hub to prevent the noise from being transmitted to the cab and affecting driving. The main sound insulation is polyester fiber cotton 1. There are many small holes inside the polyester fiber cotton 1. When the noise enters the polyester fiber cotton 1, it collides and rubs with the fibers inside. The sound energy is converted into heat energy, forming a treatment for the noise. On one side of the polyester fiber cotton 1, there are PET cotton 2 and Thinsulate sound-absorbing cotton 3 with an attractive effect. The positioning hole 4 runs through the noise treatment material. The fixed frame 5 is a "mouth"-shaped frame. The fixing frame 6 is fixed inside the fixing frame 5, and the positioning column 8 is fixed on one side of the fixing frame 6, and is arranged in a "one" shape. The distance between two adjacent positioning columns 8 is equal. A sleeve 9 is fixed on the fixing frame 6 of another fixing frame 5. The sleeve 9 is a hollow cylindrical shape, and the diameter of the sleeve 9 is larger than the diameter of the positioning column 8. A hemispherical positioning groove 7 is provided on the other side of the fixing frame 5. The clamp 10 is C-shaped, and a fixing groove 11 is provided on the clamp 10. A spring 12 is provided in the fixing groove 11. A sliding plate 13 is provided at the bottom of the spring 12. A damping ring 14 is fixed to the outside of the sliding plate 13, and a push rod 15 is fixed at the bottom end of the sliding plate 13. When the device is needed, the polyester fiber cotton 1, the PET cotton 2 and the Thinsulate sound-absorbing cotton 3 are stacked together. The positioning hole 4 passes through the three layers of noise treatment material. The positioning column 8 on one side of the fixing frame 6 on the fixing frame 5 will pass through the positioning hole 4. The other fixing frame 5 will be clamped on the other side of the noise treatment material. The sleeve 9 also enters the positioning hole 4. The positioning column 8 will be inserted into the sleeve 9 to form a positioning between the fixing frames 5 on both sides to prevent the position error between the fixing devices on both sides of the noise treatment material from causing the noise treatment materials to be misaligned with each other. There is a fixing on the clamp 10 The push rod 15 slides in the fixed groove 11 through the sliding plate 13. The damping ring 14 is arranged on the outer side of the sliding plate 13 to damp the sliding of the sliding plate 13. The spring 12 provides a directional elastic force to the sliding plate 13, so that the push rod 15 can be kept at a certain length outside the clamp 10. When the fixed frame 5 is clamped, the clamp 10 is clamped on the outer sides of the two fixed frames 5. The push rod 15 will be pressed in the positioning groove 7 under the elastic force of the spring 12, forming a mutual locking of the fixed frame 5 and the clamp 10, so as to prevent the noise treatment material from scattering or deformation caused by the clamp 10 falling off from the fixed frame 5.
