[0029] Refer to Figures 1 to 6, embodiments of the present application provide an air outlet sealing structure, which may include a lower housing 1, an upper housing 2, a deflector 4 and a spoiler 5. The lower housing 1 has a bottom wall and a plurality of side walls, and the bottom wall and the plurality of side walls enclose a receiving groove. An air inlet 11 is provided on one side wall, and an air outlet 12 is provided on the side wall adjacent to the side wall where the air inlet 11 is provided; the upper housing 2 is disposed on the side of the side wall away from the bottom wall to seal the notch of the receiving groove; the spoiler 5 is fixed to the bottom wall and is located at the air outlet 12. One end of the spoiler 5 is connected to the side wall where the air outlet 12 is provided, and the connection area is located at one end of the air outlet 12 close to the air inlet 11. The other end of the spoiler 5 is located at the end of the air outlet 12 away from the air inlet 11. The side of the spoiler 5 facing away from the bottom wall is hermetically connected to the upper housing 2.

[0030] For an air outlet sealing structure proposed in an embodiment of the present application, there may be four side walls, and the bottom wall and the plurality of side walls enclose a rectangular receiving groove. Taking the ground as a reference, when the air inlet 11 faces the ground during the use of the air outlet sealing structure, the air outlet 12 is located on both sides of the lower housing 1 in the horizontal direction at this time; one end of the spoiler 5 is connected to the side wall, and at the same time, the spoiler 5 is fixed to the bottom wall and the side of the spoiler 5 facing away from the bottom wall is hermetically connected to the upper housing 2. The air flow enters the receiving groove from the air inlet 11 and is discharged from the air outlet 12 after passing through the spoiler 5; further, one end of the spoiler 5 is connected to the side wall where the air outlet 12 is provided, and the connection area is located at one end of the air outlet 12 close to the air inlet 11. The other end of the spoiler 5 is located at the end of the air outlet 12 away from the air inlet 11. In this way, when external impurities enter the lower housing 1 from the air outlet 12, they will be blocked by the spoiler 5, and due to the influence of their own gravity, the impurities will gradually move along the spoiler 5 and finally be discharged from the air outlet 12. The spoiler 5 is fixed to the bottom wall and the side wall of the lower housing 1, and is hermetically connected to the upper housing 2, so that the impurities cannot further enter the interior of the lower housing 1 when moving on the spoiler 5, making the protection effect of the air outlet sealing structure better.

[0031] It should be understood that external impurities may include sundries, rainwater, etc. It is difficult for impurities or mosquitoes to resist the air flow at the air outlet 12 from entering the air outlet 12. Even in windy or rainy weather, when impurities enter the air outlet 12, they will slide out of the air outlet 12 along the spoiler 5. At the same time, the air flow blown out at the air outlet 12 will further push the impurities on the spoiler 5 to slide out of the air outlet 12, making the protection effect of the air outlet sealing structure better; at the same time, the air inlet 11 is below, and it is also difficult for impurities to enter the lower housing 1 from the lower air inlet 11. In this way, the heat dissipation form of lower air inlet and upper air outlet can effectively reduce the entry of rainwater, dust and mosquitoes, protect the internal electrical components and extend the service life of the whole machine.

[0032] Among them, traditional charger casings mostly use sheet metal casings, and it is impossible to make a structure with a high protection level at the air outlet. If welding is used at the air outlet to achieve high-level protection, the cost of sheet metal parts will be greatly increased. In this application, the lower shell 1, the upper shell 2, the flow guide plate 4, and the spoiler 5 are all made of plastic materials. The lower shell 1 and the upper shell 2 are fixed by screws, and finally the protective effect of air outlet sealing is achieved. Compared with using a sheet metal shell to achieve the protective effect, the cost is greatly reduced.

[0033] It should be noted that, as Figure 6 shown, the arrow represents the air flow direction.

[0034] Referring to Figure 3 and Figure 6 , in the exemplary embodiment, there are two air outlets 12, and the two air outlets 12 are opened on two opposite side walls; there are two spoiler plates 5, and the two spoiler plates 5 correspond to the two air outlets 12 one by one.

[0035] Specifically, the two air outlets 12 discharge air on both sides of the lower shell 1, and the heat dissipation effect is better. Correspondingly, there are also two spoiler plates 5, and the two spoiler plates 5 are arranged at the corresponding air outlets 12.

[0036] Referring to Figure 3 , in the exemplary embodiment, the air outlet sealing structure further includes a flow guide plate 4. The flow guide plate 4 is fixed on the side wall opposite to the air inlet 11, and the flow guide plate 4 is configured to guide the air flow to the side wall provided with the air outlet 12; the multiple side walls include a first side wall and a second side wall arranged opposite to each other, and the flow guide plate 4 is arranged on the first side wall of the lower shell 1; the flow guide plate 4 has a raised portion protruding towards the air inlet 11, and the raised surfaces on both sides of the raised portion are arc-shaped surfaces recessed towards the first side wall.

[0037] Specifically, the flow guide plate 4 is arranged in a V shape, and the opening of the V shape faces the first side wall. The flow guide plate 4 divides the air flow entering from the air inlet 11 and guides it to the two side walls of the lower shell 1 provided with the air outlets 12 respectively. In this way, it is possible to prevent the air flow from impacting the side of the lower shell 1 and causing the air flow to be scattered, and ensure the air flow effect.

[0038] Furthermore, as Figure 3 shown, the raised surfaces on both sides of the raised portion are arc-shaped surfaces recessed towards the first side wall, so that the flow guide plate 4 has a better air flow guiding effect.

[0039] Referring to Figure 4 and Figure 5 , in the exemplary embodiment, the upper shell 2 has multiple protruding portions, and each protruding portion is provided with a groove; among them, each side wall and each spoiler plate 5 correspond to a protruding portion and are inserted into the groove on the corresponding protruding portion.

[0040] Specifically, as Figure 5As shown, the side wall of the lower shell 1 is inserted into the corresponding groove to form a seal, and the spoiler 5 is also inserted into the corresponding groove to form a seal.

[0041] Furthermore, the air outlet sealing structure may further include a plurality of sealing strips 6. The plurality of sealing strips 6 correspond to the plurality of grooves one by one and are disposed in the corresponding grooves. In this way, the side wall of the lower shell 1 abuts against the corresponding sealing strip 6, and the spoiler 5 also abuts against the corresponding sealing strip 6, resulting in a better sealing effect.

[0042] It should be noted that the side walls of the lower shell 1 are connected end to end. Then, the protruding portion corresponding to the side wall of the lower shell 1 can be an annular protruding portion. Similarly, the sealing strip 6 corresponding to the side wall of the lower shell 1 can also be annular; the spoiler 5 is connected to the side wall, so the protruding portion corresponding to the spoiler 5 is connected to the protruding portion corresponding to the lower shell 1, and the corresponding grooves should also be connected. A sealing strip 6 can be disposed in each groove corresponding to each spoiler 5; of course, this is only an example and not a limitation. Specifically, how to set the grooves and how to arrange the sealing strips 6 in the grooves can be changed according to the actual situation.

[0043] Reference Figure 3 With Figure 6 , in an exemplary embodiment, the plurality of side walls include a first side wall and a second side wall disposed opposite to each other, and the air inlet 11 is disposed on the second side wall; the spoiler 5 may include a first plate 51 and a second plate 52. The first plate 51 is parallel to the side wall where the air outlet 12 is located. Among them, the maximum distance between the first plate 51 and the plane of the second side wall is a, and the maximum distance between the air outlet 12 and the plane of the second side wall is b, and a > b; the second plate 52 is perpendicular to the bottom wall and one end thereof is connected to the side wall, and the other end of the second plate 52 is connected to the first plate 51. Among them, the maximum distance between the connection area of the second plate 52 and the side wall and the plane of the second side wall is c, and the minimum distance between the air outlet 12 and the plane of the second side wall is d, and c = d. The included angle between the second plate 52 and the first plate 51 is e, and 90° < e < 180°.

[0044] Specifically, the included angle between the first plate 51 and the second plate 52 is e, and 90° < e < 180°. In this way, after impurities enter the air outlet 12, they will be blocked by the first plate 51 or the second plate 52 and fall to the second plate 52. Then, the impurities will be discharged from the air outlet 12 along the second plate 52; among them, 90° < e < 180° ensures that after the impurities fall on the second plate 52, the impurities can move along the second plate 52 under the influence of their own gravity.

[0045] Further, taking the plane where the second side wall is located as the reference plane, a is the maximum distance between all points on the first plate 51 and the reference plane, and b is the maximum distance between all points at the air outlet 12 and the reference plane. When a > b, that is, when the reference plane is a horizontal plane, the height of the first plate 51 is greater than the height of the air outlet 12. In this way, it can be ensured that impurities entering the air outlet 12 from any angle can be blocked by the first plate 51.

[0046] It should be understood that the higher the height of the first plate 51, the better the effect of blocking impurities. Specifically, the height of the first plate 51 can be selected according to the actual situation.

[0047] Further, c is the maximum distance between all points on the connection area between the second plate 52 and the side wall and the reference plane, and d is the minimum distance between all points at the air outlet 12 and the reference plane. When c = d, the connection area between the second plate 52 and the side wall is exactly at the lowest position of the air outlet 12, ensuring that impurities can all move along the second plate 52 and be discharged from the air outlet 12, and the protection effect is better.

[0048] Reference Figure 1 , in an exemplary embodiment, through holes 13 are provided on the side wall of the lower shell 1; the air outlet sealing structure may further include a maintenance plate 7 and a filter cotton 8. The maintenance plate 7 is detachably connected to the lower shell 1 and is located at the through holes 13. An air inlet 11 is provided on the maintenance plate 7. A plurality of limiting strips are provided on the side of the maintenance plate 7 facing the receiving groove, and the plurality of limiting strips enclose a clamping space; the filter cotton 8 is clamped in the clamping space.

[0049] Specifically, there may be four limiting strips, and they are arranged in pairs opposite to each other, so that the four limiting strips can enclose a rectangular clamping space, and the filter cotton 8 is clamped in the clamping space. In this way, the filter cotton 8 can further prevent impurities or mosquitoes from entering the lower shell 1 from the air inlet 11. When the filter cotton 8 is used for a long time, the maintenance plate 7 can be detached from the lower shell 1, and then a new filter cotton 8 can be replaced, and then the maintenance plate 7 is connected to the lower shell 1 to ensure the filtering effect and ventilation effect of the filter cotton 8.

[0050] Reference Figure 1 and Figure 2 , in an exemplary embodiment, the air outlet sealing structure may further include two protective nets 9. The two protective nets 9 correspond to the two air outlets 12 one by one and are slidably connected to the side of the corresponding side wall facing the first plate 51. The protective net 9 covers the corresponding air outlet 12 and has a degree of freedom to slide along the thickness direction of the bottom wall; wherein, a plurality of diversion grooves are provided at one end of the protective net 9 close to the second plate 52 and are in contact with the second plate 52, and the diversion grooves penetrate through both sides of the protective net 9.

[0051] Specifically, the outer periphery of the protection net 9 has a frame. One end of the protection net 9 away from the second plate 52 can be slidably connected to the side wall of the lower case 1. For example, a protruding structure can be provided on the side wall of the lower case 1, and a sliding groove can be provided on the protruding structure. The frame of the protection net 9 can be slidably engaged with the sliding groove to achieve the sliding of the protection net 9 along the thickness direction of the bottom wall, facilitating the replacement of the protection net 9.

[0052] Among them, as Figure 2 shown, a plurality of diversion grooves are provided at one end of the protection net 9 close to the second plate 52. The diversion grooves communicate with both sides of the protection net 9. In this way, when impurities move along the second plate 52, they can pass through the diversion grooves and be discharged from the air outlet 12, preventing the frame of the protection net 9 from affecting the discharge of impurities from the air outlet 12.

[0053] It should be noted that after the upper case 2 is connected to the lower case 1, one side of the protection net 9 close to the bottom wall abuts against the bottom wall, and one side of the protection net 9 close to the upper case 2 abuts against the upper case 2, that is, the protection net 9 cannot slide along the thickness direction of the bottom wall, ensuring that the protection net 9 covers the air outlet 12.

[0054] Based on the above embodiments, the embodiment of the present application further provides a charging device, which may include the above air outlet sealing structure and module 3. The module 3 is disposed in the receiving groove and connected to the bottom wall. A fan is provided on one side of the module 3 facing the air inlet 11, and an air outlet is provided on the side of the module 3 away from the air inlet 11.

[0055] Specifically, when the fan operates, it draws air from the air inlet 11, passes through the inside of the module 3, and blows out from the air outlet side of the module 3 to dissipate heat from the module 3; at the same time, when the fan operates, an air flow is always blown out from the air outlet 12, and it is more difficult for external impurities to enter the lower case 1 through the air outlet 12, and the protection effect is better. Among them, the charging device can be a DC charger, a charging pile, etc. Specifically, the sizes and arrangement positions of the air inlet 11 and the air outlet 12 can be adjusted according to the specific requirements of the charging device.

[0056] It should be understood that one end of the spoiler 5 away from the corresponding side wall can abut against the module 3. In this way, the spoiler 5 can seal between the module 3 and the corresponding side wall, preventing the air flow from flowing back through the gap between the module 3 and the side wall where the air outlet 12 is located.

[0057] Referring to Figure 4 , in the exemplary embodiment, the air outlet sealing structure further includes a partition 21. The partition 21 is fixed to the side of the upper case 2 facing the lower case 1 and abuts against the module 3.

[0058] Specifically, as Figure 4As shown, the spoiler 5 and the side walls of the lower case 1 are both fitted with the grooves on the corresponding raised parts. A partition 21 is fixed on the side of the upper case 2 facing the lower case 1. The partition 21 abuts against the module 3. In this way, the partition 21 can seal the gap between the module 3 and the upper case 2, so that the air flow blown out from the side of the module 3 facing away from the air inlet 11 cannot flow back to the air inlet 11 through the gap between the module 3 and the upper case 2.

[0059] Furthermore, both ends of the partition 21 can be fixed to the corresponding raised parts of the two spoilers 5. Among them, the end part of the partition 21 is located in the area corresponding to the first plate 51 and the raised part. In this way, the sealing effect of the partition 21 on the gap between the module 3 and the upper case 2 is better, so that the air flow can stably blow out from the air outlet 12, ensuring the heat dissipation effect of the whole machine and the protection effect at the air outlet 12.

[0060] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
