[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 6 The utility model provides an embodiment: an ultra-quiet charging pile, including a box body 1, which is composed of a solid box body 1. The box body 1 is in the shape of a cube, and its appearance is simple and generous. The material of the box body 1 adopts high-strength industrial-grade metal, which has good pressure resistance and wear resistance, ensuring the long-term stable operation of the charging pile. The front end of the box body 1 is rotatably connected with a cabinet door 2. The design of the cabinet door 2 allows the user to open and close it conveniently, which is convenient for maintaining and inspecting the internal structure of the charging pile. The front end of the cabinet door 2 is provided with an observation window 3. The observation window 3 adopts transparent explosion-proof glass. The user can intuitively view the working status of the charging pile through the observation window 3. At the same time, the design of the observation window 3 can also prevent the user from contacting the internal electrical components during the charging process, ensuring the safety of use. The right end of the box body 1 is fixedly connected to An exhaust silencer assembly is connected, and the exhaust silencer assembly includes an exhaust silencer cover 5 to effectively reduce exhaust noise. The left end of the exhaust silencer cover 5 is fixedly connected to the right end of the box body 1, and the outside of the exhaust silencer cover 5 is fixedly connected with an air outlet pipe 15. The air outlet pipe 15 can quickly discharge hot air to maintain a suitable temperature inside the charging pile. The left and right sides of the box body 1 are fixedly connected with a charging cable 7, and the other end of the charging cable 7 is fixedly connected with a plug 8. The other end of the plug 8 is plugged into the outside of the box body 1. When not in use, the plug 8 can be stored inside the box body 1 to prevent the plug 8 from swinging in the air, thereby improving safety of use.

[0027] The left end of the box body 1 is detachably connected with an air inlet muffler cover 6, which is an important design for reducing the noise generated when the air is inlet. The air inlet muffler cover 6 is made of high-strength plastic material, and a multi-layer muffler structure is designed inside, which can effectively reduce the noise generated when the air is inlet and improve the user experience. Since the air inlet muffler cover 6 adopts a detachable connection method, it can be easily removed when cleaning or maintenance is required. The left side of the front end of the cabinet door 2 is fixedly connected with a handle 4, and the design of the handle 4 allows the user to easily open and close the cabinet door 2.

[0028] The handle 4 is ergonomically designed, and its shape conforms to people's handshake habits, making it very comfortable to use. The handle 4 is made of metal, which has good wear resistance and pressure resistance. Even if it is used for a long time, it will not be deformed or damaged. The top of the box 1 is fixedly connected with a protective plate 9, which is designed to protect the internal components of the charging pile from external damage. The protective plate 9 is made of hard plastic material, which has good impact resistance and wear resistance, and can effectively prevent external impact or wear. The shape of the protective plate 9 is designed to completely match the top of the box 1, which can not only provide effective protection, but also will not affect the appearance of the charging pile. The outside of the air inlet silencer 6 is fixedly connected with an air inlet pipe 10, which is designed to guide the outside air into the charging pile for heat dissipation. The air inlet pipe 10 is made of elastic plastic material, which has good wear resistance and aging resistance. The left end of the box 1 is fixedly connected with an exhaust muffler 11, which is designed to reduce the noise generated during exhaust.

[0029] The exhaust muffler 11 is designed with a multi-layered sound-absorbing structure inside, which can effectively reduce the exhaust noise and improve the user experience. The bottom of the exhaust muffler 11 is fixedly connected with a sound insulation cotton 12, and the bottom of the sound insulation cotton 12 is fixedly connected with a damping plate 13. The design of the damping plate 13 is to reduce the vibration of the air flow and further reduce the noise. The bottom of the damping plate 13 is fixedly connected with a connecting pipe 14. The sound insulation cotton 12 is a porous structure. The sound insulation cotton 12 adopts a high-density polyester fiber material and has a good sound insulation effect. The sound insulation cotton 12 is a porous structure, which can effectively absorb noise and does not affect the circulation of air. The front end of the connecting pipe 14 fits with the rear end bottom of the air inlet pipe 10. The connecting pipe 14 is designed to connect the air inlet pipe 10 and the exhaust muffler 11 to form a complete ventilation system. The four corners of the bottom of the box 1 are fixedly connected with support legs. The support legs are designed to provide stable support to prevent the charging pile from tipping over. The support legs are made of high-strength metal materials and can withstand large weights to ensure the stability of the charging pile. The bottom of the support legs are designed with anti-skid pads to prevent sliding on wet floors.

[0030] Working principle: During the operation of the charging pile, air first enters the charging pile through the air inlet pipe 10 and the air inlet silencer 6 to help the internal power conversion and control equipment to dissipate heat. Then, the hot air is discharged through the exhaust silencer 5 and the air outlet pipe 15. In this process, due to the presence of the air inlet silencer 6 and the exhaust silencer assembly, the noise generated during air intake and exhaust is effectively controlled. The noise is initially controlled by the air inlet silencer 6 and the exhaust silencer assembly, and then the noise is further reduced by the sound insulation cotton 12 and the damping plate 13. Finally, the vibration of the charging pile is reduced by the supporting legs to achieve a silent effect. When exhausting, because the exhaust silencer 5 is also designed with a multi-layer silencer structure, the noise generated during exhaust can be effectively reduced, and the bottom of the exhaust silencer 11 is also fixedly connected with the sound insulation cotton 12 and the damping plate 13, these two parts can further absorb and reduce noise. The design of this charging pile fully considers the user experience, whether at home or in public places, it can be used quietly and comfortably.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
