For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0026] The terms "first," "second," etc., used in the specification, claims, and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0027] As used in this article, the terms “inner” and “outer” refer to the interior and exterior of the shell. As used in this article, “tilt” means that the object is tilted to one side in the vertical or horizontal direction relative to a reference object, that is, the object is neither parallel nor perpendicular to the reference object.

[0028] The term “multiple” as used in this article includes two or more.

[0029] To clearly illustrate the technical solution of this utility model, the following are also defined: Figure 1 The front, rear, left, right, top, and bottom sides are shown. It is understood that in this embodiment, the front-rear direction refers to the length direction of the motorcycle, the left-right direction refers to the width direction, and the top-bottom direction refers to the height direction.

[0030] like Figure 1As shown, the electric vehicle 100 includes a frame 11, a body cover 12, a walking system 13, a power system (not shown), a power battery (not shown), a portable charger 14 and a seat cushion 15. The electric vehicle 100 can be an electric bicycle, an electric two-wheeled motorcycle, an electric three-wheeled motorcycle and an electric four-wheeled motorcycle, such as an electric all-terrain vehicle, including an electric ATV, an electric UTV, etc. The body cover 12 at least partially covers the frame 11; the walking system 13 is at least partially disposed below the frame 11, and the walking system 13 includes at least one front wheel and at least one rear wheel. The power system is supported by the frame 11 and includes an electric motor (not shown); the electric motor drives the walking system 13 to move the vehicle. The portable charger 14 charges the power battery. The electric vehicle 100 further includes a containing space, such as a car pocket, and the portable charger is at least installed in the containing space.

[0031] Figure 2 The composition of the portable charger is shown, and the air guide plate of the present application is omitted. As shown, Figure 2 The portable charger 14 includes a housing 141, a circuit board module (not shown) and a heat dissipation fan 142, both of which are installed in the housing 141, the heat dissipation fan 142 is installed on the inner side wall of the housing 141, the heat dissipation fan 142 is used to dissipate heat for the housing 14 and the circuit board module, and the heat dissipation fan 142 is driven to form an air flow in the housing 141 to cool the housing 141 and the circuit board module, so that the charger can operate stably and safely.

[0032] The side wall of the housing 141 on which the heat dissipation fan 142 is installed is defined as the first side wall 1411 of the portable charger 14, and the side wall of the housing 141 opposite to the first side wall 1411 is defined as the second side wall 1412 of the portable charger 14. The housing 141 is provided with a plurality of air outlet channels 1411a on the first side wall 1411, and air outlet ribs 1411b are arranged between adjacent air outlet channels 1411a. A plurality of air inlet channels 1412a are arranged on the second side wall 1412, and air inlet ribs 1412b are arranged between adjacent air inlet channels 1412a. As shown, Figure 2 The air flow enters the inside of the housing 141 through the air inlet channel 1412a, and leaves the housing 141 through the air outlet channel 1411a and takes away the heat inside the housing 141. The installation position of the heat dissipation fan 142 on the first side wall 1411 is not limited, and can be adjusted according to the overall arrangement inside the portable charger. It can be installed on one side of the first side wall, or in the middle of the first side wall. Therefore, it should be noted that the part of the first side wall 1411 on which the air outlet channels 1411a and the air outlet ribs 1412b are arranged at least partially coincides with the part on which the heat dissipation fan 142 is installed, i.e. the part corresponding to the installation of the heat dissipation fan 142 should be provided with air outlet channels 1411a and air outlet ribs 1412b.

[0033] As Figure 2 shown, the portable charger can achieve good heat dissipation effect, but the shell is provided with the circuit board module and other circuit board elements. Due to the existence of the air inlet channel and the air outlet channel, during outdoor charging, splashed water is also easy to enter the shell, which exists a safety hazard.

[0034] As Figure 3 and Figure 4 shown, as an implementation manner, the portable charger further comprises an air guide plate 143 for guiding the flow direction of the airflow. The air guide plate 143 can be installed on the first side wall 1411, or installed on the second side wall 1412, or installed on both the first side wall 1411 and the second side wall 1412. The air guide plate 143 can be installed on the inner side of the first side wall 1411 or the second side wall 1412, or installed on the outer side of the first side wall 1411 or the second side wall 1412. The air guide plate 143 and the first side wall 1411 or the second side wall 1412 can be clamped or connected through fasteners such as rivets or bolts. Optionally, the air guide plate 143 and the first side wall 1411 or the second side wall 1412 can be integrally formed. The air guide plate 143 is provided with a plurality of air guide channels 143a corresponding to the plurality of air outlet channels 1411a or the plurality of air inlet channels 1412a, and an air guide rib 143b is arranged between adjacent air guide channels 143a. The edge of the air guide rib 143b close to the air outlet rib 1411b or the air inlet rib 1412b at least partially matches the edge of the air outlet rib 1411b or the edge of the air inlet rib 1412b to jointly form a plurality of air flow channels that are independent and not connected to each other. Thus, near the first side wall 1411 and the second side wall 1412, the airflow can flow along the respective air flow channels, avoiding flowing into other air flow channels, effectively avoiding airflow disturbance. The air guide rib 143b and the air outlet rib 1411b or the air inlet rib 1412b form a predetermined angle, and the predetermined angle is not equal to 180 degrees. Thus, each of the air flow channels is bent at the first side wall or the second side wall. When a water droplet splashes into the first side wall 1411 or the second side wall 1412, the water droplet will be blocked by the rib and will not enter the shell, improving the waterproof performance of the portable charger.

[0035] As an implementation manner, the air guide plate 143 comprises a first air guide plate 1431 and a second air guide plate 1432. The first air guide plate 1431 is installed on the inner side or the outer side of the first side wall 1411 (the air outlet side wall), and the second air guide plate 1432 is installed on the inner side or the outer side of the second side wall 1412. The first air guide plate 1431 is used to guide the flow direction of the airflow on the air outlet side of the shell, and the second air guide plate 1432 is used to guide the flow direction of the airflow on the air inlet side of the shell.

[0036] Specifically, the first air guide plate 1431 is arranged with a plurality of first air guide channels 1431a corresponding to the plurality of air outlet channels 1411a, and a first air guide rib 1431b is arranged between adjacent first air guide channels 1431a. The edge of the first air guide rib 1431b close to the air outlet rib 1411b at least partially fits the edge of the air outlet rib 1411b to form a plurality of mutually independent and unconnected airflow channels. Thus, near the first side wall 1411, the airflow can flow out of the shell along the respective air outlet airflow channel, avoiding flowing into other airflow channels, effectively avoiding airflow disturbance. The first air guide rib 1431b is inclined relative to the first side wall 1411, and the first air guide rib 1431b forms a predetermined angle with the air outlet rib 1412b or the air inlet rib 1412b, and the predetermined angle is not equal to 180 degrees. When the first air guide plate 1431 is installed on the inner side of the first side wall 1411, each air outlet channel 1411a and each first air guide channel 1431a together form an airflow outlet channel. When viewed from the outside to the inside of the shell 141, each air outlet channel on the first side wall 1411 is at least partially blocked by the first air guide rib 1431b. Therefore, when the splashed water droplets enter through the air outlet channel 1141a on the first side wall 1411, the water droplets will be blocked by the first air guide rib 1431b and will not enter the inside of the shell 141, thus improving the waterproof performance of the air outlet side wall of the portable charger 14. As shown in Figure 5 and Figure 6 When the first air guide plate 1431 is installed on the outer side of the first side wall 1411, each air outlet channel 1411a and each first air guide channel 1431a together form an airflow outlet channel with a turning portion. When viewed from the inside to the outside of the shell 141, each air outlet channel on the first side wall 1411 is at least partially blocked by the first air guide rib 1431b. Because the first air guide rib 1431b is inclined relative to the first side wall 1411, the splashed water droplets will be blocked by the first air guide rib 1431b and will not enter the inside of the shell 141, thus improving the waterproof performance of the air outlet side wall of the portable charger 14.

[0037] The second air guide plate 1432 is provided with a plurality of second air guide channels 1432a corresponding to the plurality of air inlet channels 1412a, and a second air guide rib 1432b is arranged between adjacent second air guide channels 1432a. The edge of the second air guide rib 1432b close to the air inlet rib 1412b at least partially fits the edge of the air inlet rib 1412b to jointly form a plurality of independent air inlet flow channels. Thus, near the second side wall 1412, the air flow can flow into the shell along the respective air inlet flow channel, avoiding flowing into other air flow channels, effectively avoiding air flow disturbance. The second air guide rib 1432b is inclined relative to the second side wall 1412, and the second air guide rib forms a predetermined angle with the air inlet rib 1412b. The predetermined angle is not equal to 180 degrees. When the second air guide plate 1432 is installed on the inner side of the second side wall 1412, each air inlet channel 1412a and each second air guide channel 1432a jointly form an air inlet flow channel, which is bent at the second side wall 1412. When viewed from the inside to the outside of the shell 141, each air inlet channel on the second side wall 1412 is at least partially blocked by the second air guide rib 1432b. Therefore, when the splashed water droplets enter through the air inlet channel 1142a on the second side wall 1412, the water droplets are blocked by the second air guide rib 1432b and cannot enter the inside of the shell 141, thereby improving the waterproof performance of the air inlet side wall of the portable charger 14. Figure 5 and Figure 6 As shown in FIGS. 11 and 12, when the second air guide plate 1432 is installed on the outer side of the second side wall 1412, each air inlet channel 1412a and each second air guide channel 1432a jointly form an air inlet flow channel with a turning portion. When viewed from the inside to the outside of the shell 141, each air inlet channel on the second side wall 1412 is at least partially blocked by the second air guide rib 1432b. Because the second air guide rib 1431b is inclined relative to the second side wall 1412, the splashed water droplets are blocked by the second air guide rib 1431b and cannot enter the inside of the shell 141, thereby improving the waterproof performance of the air inlet side wall of the portable charger 14.

[0038] The predetermined angle is in the range of 110 degrees to 160 degrees, preferably 120 degrees to 150 degrees, and more preferably 130 degrees to 140 degrees. The presence of the predetermined angle allows the splashed water droplets to be blocked outside the shell, thereby improving the waterproof performance of the portable charger.

[0039] As an implementation manner, in the cross-sectional view of the first side wall 1411 or the cross-sectional view of the second side wall 1412, the air outlet channel or the air inlet channel has a substantially trapezoidal shape and the width of the air outlet channel or the air inlet channel gradually decreases when viewed from the outside to the inside. Thus, a part of the splashed water droplets can also be blocked.

[0040] As an implementation, the minimum width of the air-out rib or the minimum width of the air-in rib 1412b is greater than or equal to the width of the air-drawing rib 143b in the cross-sectional view of the first side wall 1411 or the cross-sectional view of the second side wall 1412.

[0041] As an implementation, the edge of the air-drawing rib 143b close to the air-out rib or the air-in rib 1412b is completely fitted to the edge of the air-out rib or the edge of the air-in rib 1412b.

[0042] In the present application, by installing the air-drawing plate on both sides of the shell 141, setting the air-drawing channel and the air-drawing rib on the air-drawing plate, forming a plurality of mutually independent and non-communicating airflow channels, the airflow guiding of the ventilation is simple and smooth, and each of the airflow channels is bent at the first side wall or the second side wall, which can improve the waterproofness of the shell 141.

[0043] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
