[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please also read Figure 1 , Figure 2 and Figure 3 , Figure 1 1 is a schematic diagram of the three-dimensional structure of a charging pile 1000 provided in an embodiment of the present invention; Figure 2 yes Figure 1 The three-dimensional structural schematic diagram of the charging pile 1000 shown in another viewing angle;

[0031] Figure 3 yes Figure 1 A schematic diagram of the internal structure of the charging pile 1000 is shown in FIG.

[0032] The embodiment of the present application provides a charging pile 1000, which includes a pile body 100 and a charging component 200. The charging component 200 is arranged in the pile body 100 to realize the corresponding charging function, and the pile body 100 plays a role of encapsulation and protection for the charging component 200. Among them, the pile body 100 includes an air cavity 101, an air inlet 102 and an air outlet 103. The charging component 200 is accommodated in the air cavity 101. The air inlet 102 and the air outlet 103 connect the air cavity 101 with the outside world. The air can enter the air cavity 101 from the air inlet 102, and pass through the charging component 200 and then be discharged from the air outlet 103, thereby taking the heat generated by the charging component 200 out to the outside world to reduce the temperature of the charging component 200.

[0033] It can be understood that, in this embodiment, the bottom ends of the air inlet 102, the air cavity 101 and the air outlet 103 are flush, and the dimensions of the above three are the same along the height direction of the pile body 100. Under the above structure, the air inlet 102, the air cavity 101 and the air outlet 103 are at the same horizontal height, and the height dimensions are the same. When the air passes through the air inlet 102, the air cavity 101 and the air outlet 103 in sequence, the cross-section of the air flow channel remains consistent in height dimension, and only has certain changes in the lateral dimension, so that the air will not produce a large local pressure loss due to the frequent changes in the height dimension of the air duct when flowing, and the internal airflow resistance of the charging pile 1000 is effectively reduced.

[0034] In one embodiment, the charging pile 1000 further includes an electrical component 500, which is disposed in the pile body 100. The electrical component 500 cooperates with the charging component 200 to charge the vehicle to be charged. The structure of the electrical component 500 is not specifically limited herein.

[0035] The charging pile 1000 provided in the embodiment of the present application is configured such that the bottom ends of the air inlet 102, the air cavity 101 and the air outlet 103 are flush, and in the height direction of the pile body 100, the air inlet 102, the air cavity 101 and the air outlet 103 are the same size, so that when the air flows in the charging pile 1000, the cross-section of the passage through which the air flows remains consistent in height dimension, and the air will not generate large local pressure loss due to frequent changes in the height dimension of the air duct when flowing, thereby effectively reducing the internal airflow resistance of the charging pile 1000, increasing the airflow volume of the charging pile 1000, and thereby reducing the temperature of the charging component 200, thereby improving the charging efficiency of the charging pile 1000.

[0036] Please also read Figures 3 to 6 , Figure 4 yes Figure 1 The three-dimensional structural schematic diagram of the charging pile 1000 shown in another viewing angle; Figure 5 yes Figure 4 A schematic diagram of the three-dimensional structure of the charging component 200 in the charging pile 1000 is shown;

[0037] Figure 6 yes Figure 5 The three-dimensional structural schematic diagram of the charging assembly 200 is shown in another viewing angle.

[0038] In one embodiment, the charging assembly 200 includes a first opening 201 and a second opening 202 that are arranged opposite to each other. The first opening 201 and the second opening 202 connect the interior of the charging assembly 200 with the air cavity 101. The air entering from the air inlet 102 enters the charging assembly 200 through the first opening 201 and is discharged from the second opening 202. In the height direction along the pile body 100, the size of the air cavity 101 is greater than or equal to the size of the first opening 201. It can be understood that when the charging assembly 200 performs the corresponding charging function, the internal heat is serious and is the main source of heat. In this embodiment, the charging assembly 200 is a through structure. Air can enter the interior of the charging assembly 200 through the first opening 201 and then be discharged from the second opening 202 to effectively remove the internal heat of the charging assembly 200, thereby achieving a better heat dissipation effect.

[0039] It can also be understood that when air flows inside the charging component 200 to take away the heat inside it, if the air flow rate at each position inside it is uneven, it will cause the heat dissipation effect at each position inside the charging component 200 to be inconsistent, and it is difficult to meet the corresponding heat dissipation requirements at the same time. In this embodiment, along the height direction of the pile body 100, the size of the wind cavity 101 is greater than or equal to the size of the first opening 201, so that the air in the wind cavity 101 can evenly cover the first opening 201, so that the flow rate of the air entering each position inside the charging component 200 from the first opening 201 is the same and uniform, and the heat dissipation effect at each position inside the charging component 200 can meet the corresponding heat dissipation requirements at the same time, further improving the heat dissipation effect of the charging pile 1000, so that the charging efficiency of the charging pile 1000 is effectively improved.

[0040] Please refer again Figure 3 In one embodiment, a partition 10 is further provided in the pile body 100. The partition 10 and the charging assembly 200 jointly divide the air cavity 101 into an air inlet duct 1011 and an air outlet duct 1012. The air inlet duct 1011 is connected to the air inlet 102 and the first opening 201, and the air outlet duct 1012 is connected to the air outlet 103 and the second opening 202. It can be understood that the partition 10 and the charging assembly 200 jointly divide the air cavity 101 in the pile body 100 into a plurality of interconnected spaces, such as the air inlet duct 1011 and the air outlet duct 1012, thereby increasing the surface area of ​​the internal space of the pile body 100 while keeping the volume of the pile body 100 unchanged, so that the noise generated inside the charging pile 1000 can be reflected multiple times in the internal space of the pile body 100. After each reflection and absorption, the sound energy gradually decays to achieve a better noise reduction effect, and the charging pile 1000 can still maintain a small volume to reduce costs.

[0041] Among them, a first sound absorbing member 20 is provided on the partition 10 and the inner wall of the pile body 100, and the first sound absorbing member 20 is used to absorb the noise generated by the charging pile 1000. It can be understood that in the charging pile 1000, the charging component 200 is the main noise source, and in the embodiment of the present application, the interior of the charging component 200 is connected to the outside only through the first opening 201 and the second opening 202. Therefore, the noise generated inside the charging component 200 can only be transmitted to the outside through the first opening 201 through the air inlet duct 1011, or transmitted to the outside through the second opening 202 through the air outlet duct 1012. Under the above structure, by setting the first sound absorbing member 20 on the inner wall of the partition 10 and the pile body 100, the air inlet duct 1011 and the air outlet duct 1012 are covered with the first sound absorbing member 20, and the noise generated inside the charging assembly 200 will be absorbed by the first sound absorbing member 20 when passing through the air inlet duct 1011 and the air outlet duct 1012, and most of the noise cannot be transmitted to the outside, thereby effectively improving the noise reduction effect of the charging pile 1000. It should be noted that the first sound absorbing member 20 includes but is not limited to sound absorbing cotton, and can also be any other structure with sound absorbing function, and the structure of the first sound absorbing member 20 is not specifically limited here.

[0042] In one embodiment, the total sound absorption area of ​​the first sound absorbing member 20 located in the air inlet duct 1011 is greater than or equal to 4 times the area of ​​the air inlet 102. It can be understood that when the total sound absorption area of ​​the first sound absorbing member 20 in the air inlet duct 1011 is large, and the area ratio of the first sound absorbing member 20 to the air inlet 102 is greater than or equal to 4, the first sound absorbing member 20 can effectively absorb the noise transmitted through the air inlet duct 1011. According to the sound intensity theory, the above structure can reduce the noise by at least 7db, so that the charging pile 1000 can effectively achieve the corresponding noise reduction requirements.

[0043] In one embodiment, the air inlet duct 1011 is of a zigzag structure, so that the noise will be reflected multiple times when passing through the air inlet duct 1011. It is understandable that the air inlet duct 1011 connects the air inlet 102 and the first opening 201. When the air inlet duct 1011 separated by the partition 10 and the charging assembly 200 is of a zigzag structure, the noise will be reflected multiple times during the propagation in the zigzag air inlet duct 1011, and each reflection will attenuate the sound energy of the noise, thereby achieving a better noise reduction effect.

[0044] Please also read Figure 7 and Figure 8 , Figure 7 yes Figure 2 A schematic diagram of the three-dimensional structure of the air inlet assembly 300 in the charging assembly 200 is shown; Figure 8 yes Figure 7 A cross-sectional schematic diagram of the air inlet assembly 300 is shown.

[0045] In one embodiment, an air inlet assembly 300 is further provided at the air inlet 102. The air inlet assembly 300 includes a fixing member 31 and a filter member 32. The fixing member 31 is used to fix the filter member 32. The filter member 32 covers the air inlet 102 to filter impurities in the air. It is understandable that the presence of the air inlet assembly 300 can effectively filter the air that will enter the charging pile 1000. Among them, the fixing member 31 is used to fix the filter member 32. The fixing member 31 includes but is not limited to a fixed frame and a pressure strip, and can also be any other structure with a corresponding fixing function. The type of the fixing member 31 is not specifically limited herein. Similarly, the filter member 32 includes but is not limited to a wire mesh and dustproof cotton, and can also be any other structure with a corresponding filtering function. The type of the filter member 32 is not specifically limited herein.

[0046] Please also read Figures 9 to 12 , Fig. 9 yes Figure 1 The three-dimensional structural schematic diagram of the charging pile 1000 shown in another viewing angle; Fig.10 yes Fig. 9 A schematic diagram of the three-dimensional structure of the air outlet assembly 400 in the charging pile 1000 is shown; Fig.11 yes Fig.10 The three-dimensional structural schematic diagram of the air outlet assembly 400 in another viewing angle is shown; Fig.12 yes Fig.11 A cross-sectional schematic diagram of an air outlet assembly 400 is shown.

[0047] In one embodiment, an air outlet assembly 400 is also provided at the air outlet 103, and the air outlet assembly 400 includes a first fixed plate 41, a second sound absorbing member 42 and a plurality of fans 43. In the height direction of the pile body 100, a plurality of fans 43 are arranged side by side and at intervals on the first fixed plate 41 to extract the air in the air cavity 101, and a second sound absorbing member 42 is provided between at least two adjacent fans 43. It can be understood that the presence of a plurality of fans 43 can extract the air in the air cavity 101, so that the air can flow quickly inside the charging pile 1000 to achieve a corresponding cooling effect. The first fixed plate 41 is used to fix a plurality of fans 43, and in the height direction of the pile body 100, a plurality of fans 43 are arranged side by side and at intervals on the first fixed plate 41 to achieve a uniform distribution of the plurality of fans 43, so that the air flow rate at each position in the air cavity 101 is the same, so as to achieve the purpose of uniform heat dissipation. It can also be understood that the fan 43 is also one of the main noise sources inside the charging pile 1000. When multiple fans 43 are working, noise will be generated. Therefore, a second sound absorbing member 42 is provided between at least two adjacent fans 43 to effectively absorb the noise generated by the multiple fans 43 to achieve the corresponding noise reduction function.

[0048] In one embodiment, the air outlet assembly 400 further includes a second fixed plate 44, the second fixed plate 44 is opposite to the first fixed plate 41 and is arranged at intervals, and a plurality of sub-air outlets 401 are provided on the second fixed plate 44, and in the height direction along the pile body 100, the plurality of sub-air outlets 401 are arranged side by side and at intervals, and the plurality of sub-air outlets 401 and the plurality of fans 43 are staggered with each other. It can be understood that under the above structure, the air in the air cavity 101 is extracted by the plurality of fans 43 and then discharged to the outside by the plurality of sub-air outlets 401. Moreover, in the height direction along the pile body 100, the plurality of sub-air outlets 401 are arranged side by side and at intervals on the second fixed plate 44 to achieve uniform arrangement of the plurality of sub-air outlets 401, so that the air in the air cavity 101 can be uniformly discharged to the outside by the plurality of sub-air outlets 401 to achieve the purpose of uniform heat dissipation. It can also be understood that, in the present embodiment, the multiple sub-air outlets 401 and the multiple fans 43 are staggered with each other, so that the noise generated by the operation of the fans 43 will not be transmitted directly from the sub-air outlets 401, but will be reflected multiple times in the space where the two are staggered before being transmitted from the sub-air outlets 401, which consumes the energy of the noise to a certain extent and achieves the corresponding noise reduction effect.

[0049] In one embodiment, the air outlet assembly 400 further includes a plurality of third sound absorbing members 45, a third sound absorbing member 45 is provided between each two adjacent sub-air outlets 401, and the plurality of third sound absorbing members 45 and the plurality of fans 43 are arranged opposite to each other. It is understandable that, since the plurality of sub-air outlets 401 and the plurality of fans 43 are staggered with each other, a third sound absorbing member 45 can be provided between each two adjacent sub-air outlets 401, and the plurality of third sound absorbing members 45 and the plurality of fans 43 are arranged opposite to each other, so that the third sound absorbing member 45 can further absorb the noise generated by the plurality of fans 43, further improving the noise reduction effect of the charging pile 1000, and effectively improving the charging efficiency of the charging pile 1000.

[0050] In one embodiment, the total sound absorption area of ​​the second sound absorbing member 42 and the third sound absorbing member 45 is greater than or equal to 3.5 times the total area of ​​the multiple sub-air outlets 401. It can be understood that when the total sound absorption area of ​​the second sound absorbing member 42 and the third sound absorbing member 45 in the air outlet assembly 400 is large, and the area ratio of the two to the multiple sub-air outlets 401 is greater than or equal to 3.5, the second sound absorbing member 42 and the third sound absorbing member 45 can effectively absorb the noise transmitted by the fan 43. According to the sound intensity theory, the above structure can reduce the noise by at least 6.2db, so that the charging pile 1000 can effectively achieve the corresponding noise reduction requirements. It should be noted that the second sound absorbing member 42 and the third sound absorbing member 45 include but are not limited to sound absorbing cotton, and can also be any other structure with sound absorption function. The structure of the second sound absorbing member 42 and the third sound absorbing member 45 is not specifically limited here.

[0051] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
