[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0034] At present, new energy vehicle charging sockets are all equipped with a drainage structure to ensure that the accumulated water in the charging seat is discharged in time to prevent the accumulation of water from affecting charging. The drainage design of existing products does not take into account the backflow problem when there is a lot of water accumulation or the accumulated water is not discharged in time. If the accumulated water flows back into the cavity of the charging seat, the charging may fail due to the failure of the insulation withstand voltage between the terminals. In addition, when the existing products are manufactured and formed, in order to facilitate demolding, a slider to form a drainage port needs to be set on the mold, resulting in high production costs.

[0035] To this end, the present application provides a charging stand that can prevent rainwater from flowing back into the cavity of the charging stand as much as possible, ensuring the insulation effect between the terminals. It can also omit the design of the slider on the mold and reduce production costs. The structure of the charging stand provided by the present application is described below.

[0036] See also Figure 1 and Figure 2 The charging seat includes a charging panel 10 and a charging base 20. The charging panel 10 is mounted on the vehicle body, and the charging base 20 is mounted on the charging panel 10. It can be understood that two charging bases 20 are provided on each charging panel 10, one is a fast charging base, and the other is a slow charging base. The embodiment of the present application takes one of the charging bases 20 as an example for explanation. After the charging panel 10 and the charging base 20 are assembled, a plug-in cavity 30 is formed between the charging panel 10 and the charging base 20, and the charging gun can be inserted into the plug-in cavity 30. The insertion direction of the charging gun is the first direction X. The charging panel 10 also has a first direction Y and a first direction Z. The first direction X, the first direction Y and the first direction Z are perpendicular to each other, and the first direction Y is Figure 1 The width direction of the charging panel 10, the first direction Z is Figure 1 The length direction of the charging panel 10 is shown in FIG.

[0037] See also Figure 2 and Figure 3The charging panel 10 is provided with a drainage groove 110, which is connected to the plug-in cavity 30. The drainage groove 110 is provided at the bottom of the plug-in cavity 30, and is connected to the external space. The drainage groove 110 is used to supply water to drain out of the plug-in cavity 30. A drainage cavity 120 is provided on the charging panel 10 between the plug-in cavity 30 and the drainage groove 110. A flow blocking member 130 is provided in the drainage cavity 120. The flow blocking member 130 divides the drainage cavity 120 into a first drainage channel 121 and a second drainage channel 122. The first drainage channel 121 is provided between the plug-in cavity 30 and the second drainage channel 122. A drainage port 140 is provided on the charging panel 10. The first drainage channel 121 is connected to the plug-in cavity 30 through the drainage port 140, the second drainage channel 122 is connected to the first drainage channel 121, and the drainage groove 110 is connected to the second drainage channel 122.

[0038] When there is a lot of accumulated water or the accumulated water is not discharged in time, backflow is likely to occur, that is, the accumulated water enters the plug-in cavity 30 from the drainage groove 110. The present application divides the drainage cavity 120 into a first drainage channel 121 and a second drainage channel 122 by setting a flow blocking member 130. The accumulated water first enters the second drainage channel 122 from the drainage groove 110. After the accumulated water in the second drainage channel 122 reaches a certain height, the accumulated water will enter the first drainage channel 121. After the accumulated water in the first drainage channel 121 reaches a certain height, the accumulated water will enter the plug-in cavity 30. Therefore, by setting the first drainage channel 121 and the second drainage channel 122, when there is too much accumulated water or it is not discharged in time, the flow path of the accumulated water can be extended, thereby avoiding backflow as much as possible.

[0039] It is understandable that, in other embodiments, a plurality of baffles 130 may be provided, and the drainage cavity 120 may also be divided into a plurality of channels by the baffles 130 to further extend the flow path of the accumulated water, which is not limited here.

[0040] For details, see Figure 3 , the first drainage channel 121 and the second drainage channel 122 both extend along the first direction X, the length of the second drainage channel 122 in the first direction X is greater than the length of the first drainage channel 121 in the first direction Y; the volume of the second drainage channel 122 is greater than the volume of the first drainage channel 121. Therefore, when there is a lot of accumulated water or the accumulated water is not discharged in time, the amount of accumulated water in the second drainage cavity 120 can be increased, further preventing the accumulated water from entering the first drainage channel 121, which helps to achieve a better anti-backflow effect.

[0041] For further information, see Figure 3 and Figure 4 , Figure 4 yes Figure 3Enlarged view of point A in the middle. The baffle 130 includes a connecting portion 132 and a baffle 133, and the connecting portion 132 and the baffle 133 cooperate to divide the drainage chamber 120 into a first drainage channel 121 and a second drainage channel 122. Two connecting portions 132 are provided in the present application, and the connecting portions 132 are respectively provided on both sides of the baffle 133 in the second direction Y, and the side of the connecting portion 132 away from the baffle 133 is fixedly connected to the charging panel 10. In this embodiment, the connecting portion 132 and the baffle 133 are integrally formed, and the cross-section of the baffle 130 is U-shaped. A first drainage hole 131 is provided on the connecting portion 132, and the second drainage channel 122 is connected to the first drainage channel 121 through the first drainage hole 131. The first drainage hole 131 penetrates the connecting portion 132 along the second direction Y, and the drainage groove 110 and the drainage port 140 are both penetrated along the third direction Z.

[0042] Since the first drainage hole 131 is arranged along the second direction, and the drainage groove 110 and the drainage port 140 are arranged along the third direction Z, when there is a lot of accumulated water or the accumulated water is not discharged in time, if the accumulated water enters the second drainage channel 122 from the drainage port 140, the accumulated water needs to change its flow direction once before entering the second drainage channel 122, and then change its flow direction again before entering the plug-in cavity. Therefore, by setting the first drainage hole 131, the drainage groove 110 and the drainage port 140 in different directions, the technology can change the flow direction multiple times in the drainage cavity 120 to lengthen the flow path of the accumulated water, thereby avoiding the problem of backflow of the accumulated water as much as possible.

[0043] Specifically, a plurality of first drainage holes 131 are provided, specifically two in this embodiment, and the two first drainage holes 131 are respectively provided on the two connecting portions 132. By providing a plurality of first drainage holes 131, a good drainage effect can be achieved while avoiding the backflow of accumulated water as much as possible, so that the accumulated water in the plug cavity 30 can be discharged smoothly.

[0044] In addition, the drainage groove 110 extends along the first direction X to the edge of the charging panel 10, and an opening is formed on one side of the charging panel 10. When producing the charging panel 10, the drainage groove 110 structure can be directly formed by injection molding, and there is no need to set a slider on the mold, which is convenient for direct demolding. Therefore, the charging seat structure provided in this application can simplify the design of the mold, reduce the production of products, and improve production efficiency. The first drainage hole 131 extends along the first direction X to the edge of the connecting part 132, and an opening is formed on the side of the connecting part 132 close to the drainage groove 110. The drainage cavity 120 is divided into a first drainage channel 121 and a second drainage channel 122 by the baffle 130, and the first drainage hole 131 is set at the edge of the connecting part 132. When producing the charging panel 10, the first drainage hole 131 structure can be directly formed by injection molding, and there is no need to set a slider on the mold, which is convenient for direct demolding. Therefore, the charging seat structure provided in this application can simplify the design of the mold, reduce the production of products, and improve production efficiency.

[0045] In some embodiments, see Figure 5 , the charging panel 10 has a reference plane m extending along the first direction X, the drain port 140 has a first orthographic projection on the reference plane m, the first drain hole 131 has a second orthographic projection on the reference plane m, and the second orthographic projection is located on the side of the first orthographic projection away from the plug-in cavity 30 in the first direction X. That is to say, in this embodiment, the drain port 140 and the first drain hole 131 are staggered in the third direction Z. Therefore, if the accumulated water enters the second drainage channel 122, the flow path of the accumulated water can be extended, achieving a good anti-backflow effect.

[0046] In some embodiments, the drain groove 110 has a third orthographic projection on the reference plane m, and the third orthographic projection is located on the side of the second orthographic projection away from the plug-in cavity 30 in the first direction X. That is, in this embodiment, the drain groove 110 and the first drain hole 131 are staggered in the third direction Z. Thus, it is possible to avoid as much as possible that the accumulated water does not accumulate in the second drainage channel 122 but directly enters the first drainage channel 121 from the drain port 140 and the first drainage hole 131, thereby ensuring that the flow path of the accumulated water is extended and as much as possible, the accumulated water is avoided from flowing back.

[0047] For details, see Figure 3 A guide surface 123 is provided in the second drainage channel 122. The guide surface 123 is an inclined surface. The side of the guide surface 123 away from the flow blocking member 130 is inclined toward the side close to the drainage groove 110. When draining water, water enters the second drainage channel 122 from the first drainage hole 131. Under the action of the guide surface 123, the water can flow out of the drainage groove 110 along the inclined direction of the guide surface 123, which helps to achieve a better drainage effect and avoid rainwater accumulation in the second drainage channel 122 as much as possible.

[0048] In some embodiments, see Figure 6 and Figure 7 The charging base 20 is provided with a plurality of terminal holes 210 for inserting terminals, and a guide channel 220 is provided between the terminal holes 210. A guide groove 230 is provided on the charging base 20. The guide channel 220 and the plug-in cavity 30 are connected by the ventilation pipe guide groove 230, and the guide groove 230 is provided on a side close to the drainage cavity 120. When the charging gun is inserted into the plug-in cavity 30, the guide channel 220 guides the water of the charging gun into the guide groove 230, and the water flows from the guide groove 230 into the plug-in cavity 30, and then enters the drainage cavity 120 from the drainage port 140, and finally is discharged from the drainage groove 110 together, which helps to achieve a better drainage effect.

[0049] The principle of the embodiment of the present application is as follows: when the charging gun is inserted into the plug-in cavity 30, part of the rainwater on the charging gun enters the first drainage channel 121 from the drainage port 140, then enters the second drainage channel 122 through the first drainage hole 131, and finally is discharged from the drainage groove 110. Part of the rainwater is discharged from the diversion groove 230 through the diversion channel 220, and is discharged from the drainage groove 110 together with the rainwater in the plug-in cavity 30. If there is a lot of accumulated water or the accumulated water is not discharged in time, the accumulated water enters the second drainage channel 122 from the drainage groove 110. After the accumulated water in the second drainage channel 122 reaches a certain height, the accumulated water will enter the first drainage channel 121 from the first drainage hole 131. After the accumulated water in the first drainage channel 121 reaches a certain height, the accumulated water will enter the plug-in cavity 30 from the first drainage channel 121, thereby greatly reducing the possibility of rainwater backflowing into the plug-in cavity 30, ensuring good insulation and charging effects.

[0050] In addition, the present application also provides a vehicle, including the above-mentioned charging seat. The vehicle provided by the present application can ensure good drainage effect during charging, and can also try to avoid the backflow of accumulated water into the plug cavity 30, causing insulation withstand voltage failure between terminals and resulting in charging failure.

[0051] The above description is only a partial implementation method of the embodiments of the present application and does not constitute any form of limitation on the application. The protection scope of the embodiments of the present application is not limited thereto. Any simple modifications, equivalent changes and modifications that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the embodiments of the present application should be covered within the protection scope of the embodiments of the present application.
