The setting of the sound insulation components is beneficial to the damping absorption of noise, vibration reduction and noise reduction, thereby preventing excessive noise from affecting the surrounding residents. The setting of the ventilation and exhaust ports does not affect the ventilation and heat dissipation of the charging pile, thereby ensuring the ventilation and heat dissipation effect while providing sound insulation and noise reduction. The vibration-damping cotton can absorb vibration and reduce the generation of noise.
[0008] Furthermore, the outer shell of the sound insulation cover is a rectangular parallelepiped structure.

[0022] Example:
[0023] like Figure 1-Figure 3 As shown, the present embodiment provides a sound insulation and noise reduction processing device for the ventilation and exhaust port 4 of a new energy vehicle charging pile, comprising a sound insulation cover shell 1, the sound insulation cover shell 1 is formed with a groove 2, the side wall edge of the groove 2 is extended outward with a rib 3, the rib 3 is formed around the side wall edge of the groove 2, and the rib 3 is vertically arranged to the side wall of the groove 2; a ventilation and exhaust port 4 is arranged on the side surface of one end in the length direction of the sound insulation cover, a sound insulation component 5 is arranged on the bottom surface of the groove 2, a circle of vibration-damping cotton 6 is arranged on the inner side surface of the groove 2, an adhesive strip 7 is attached to the inner side surface of the rib 3, and a plurality of mounting holes are opened on the rib 3.
[0024] The specific working process and principle are as follows:
[0025] When in use, the sound insulation cover shell 1 is fixed to the ventilation and heat dissipation of the charging pile by means of bolts passing through the mounting holes and the retaining edges 3, and the sound insulation cover shell 1 is fitted to the surface of the charging pile by means of adhesive strips 7, which plays a role in auxiliary installation. The setting of the sound insulation component 5 is beneficial to the damping absorption of noise, vibration reduction and noise reduction, and prevents excessive noise from affecting the surrounding residents. The setting of the ventilation and exhaust port 4 does not affect the ventilation and heat dissipation of the charging pile, and ensures its ventilation and heat dissipation effect while soundproofing and reducing noise. The vibration-damping cotton 6 can absorb vibration and reduce noise generation.
[0026] In another embodiment of the present invention, Figure 1 and Figure 2 As shown, the soundproof cover shell 1 is a rectangular parallelepiped structure.
[0027] The sound insulation cover shell 1 with a rectangular structure is more conducive to cooperation with the charging pile.
[0028] In another embodiment of the present invention, Figure 2 As shown, the ventilation outlet 4 completely penetrates the side where it is located, and the groove 2 is a structure surrounded by three sides.
[0029] The provision of the completely through ventilation and exhaust port 4 is conducive to achieving the ventilation and heat dissipation effect of the sound insulation cover shell 1 to the greatest extent, and prevents the ventilation and heat dissipation of the charging pile from being affected.
[0030] In another embodiment of the present invention, Figure 3 As shown, the sound insulation component 5 includes a first sound absorbing panel 51, sound insulation cotton 52 and a second sound absorbing panel 53 which are arranged from the inside to the outside at the bottom of the groove 2. The shapes and areas of the first sound absorbing panel 51, sound insulation cotton 52 and the second sound absorbing panel 53 match the bottom surface shape of the groove 2.
[0031] The first sound absorbing panel 51 , together with the sound insulation cotton 52 and the second sound absorbing panel 53 , can more fully absorb the sound volume and ensure the noise reduction effect.
[0032] In another embodiment of the present invention, Figure 2 As shown, the vibration-proof cotton 6 has a U-shaped structure.
[0033] The provision of the vibration-damping cotton 6 reduces the resonance state of the low-frequency noise.
[0034] Noise reduction effect: sound insulation 25~40dB

[0037] The technical solution of this application is sound absorption, damping, shock absorption, and noise reduction. It is a solution to the low-frequency resonance noise reduction in the operation of the charging pile module. At the same time, the heat dissipation problem of the charging pile is taken into consideration, and a sufficiently large exhaust port is set to ensure that the wind speed and air volume of the charging pile are not affected, thereby not affecting ventilation and heat dissipation, but not completely isolating the noise.
