As an alternative embodiment, the light strip 192 may be disposed on a side close to the meter, and the light strip 192 may be disposed on the longitudinal plane S2, extending substantially in the front-rear direction of the electric motorcycle 100, and being substantially bilaterally symmetrical with respect to the longitudinal plane S2, in such a manner that a better view of the light strip 192 is obtained. Still further, the light strip 192 may be formed of two parts, defining the two parts of the light strip 192 as a front light strip 1922 and a rear light strip 1923, respectively, the front light strip 1922 being disposed substantially on the front side of the display screen 191 and the rear light strip 1923 being disposed substantially on the rear side of the display screen 191. The front light strip 1922, the display screen 191, and the rear light strip 1923 extend in the front-rear direction on the upper end surface 1213, and substantially penetrate the upper end surface 1213, that is, one end of the rear light strip 1923 is connected to the display screen 191, and the other end of the rear light strip 1923 abuts against the seat cushion 123. The arrangement mode can visually show the visual effect that the lamp strip 192 penetrates through the display screen 191, and the front lamp strip 1922, the display screen 191 and the rear lamp strip 1923 visually form a continuous signal area which is respectively used for displaying different signals, so that key information of vehicle conditions can be quickly obtained, and the display screen is more attractive in vision. Of course, the light strip 192 may be provided in two parts, or may be provided as a single piece or in multiple parts.

Specifically, the light bands 192 may be preset to present corresponding information content in different scenes in different colors and in a blinking state. As an alternative embodiment, different levels of state of charge reserve may be represented by different preset colors. For example, when the battery pack 14 is sufficiently charged, the light strip 192 displays a green light signal, when the battery pack 14 is not sufficiently charged for a preset mileage, the light strip 192 displays a yellow light signal, and when the battery pack 14 is severely insufficiently charged for charging, the light strip 192 displays a red light. The state of charge may also be indicated by different flashing signals, for example, the light strip 192 does not flash, indicating that the battery assembly 14 is sufficiently charged, the light strip 192 flashes at a predetermined rate when the battery assembly 14 is not sufficiently charged for a predetermined range, and the light strip 192 flashes rapidly when the battery assembly 14 is severely insufficiently charged for charging. It will be appreciated that other information such as vehicle status, vehicle gear, etc. may also be displayed by color and flashing. Alternatively, one type of vehicle information is displayed by color, and another different type of vehicle information is displayed by blinking, for example, the amount of electricity of the battery assembly 14 is displayed by color, and the blinking signal displays the vehicle state. The vehicle information displayed on the light strip 192 may be content displayed on the display screen 191 already provided with the display module, or may be content displayed on the display screen 191 not provided with the display module. This arrangement can amplify the vehicle information signal of the electric motorcycle 100, and can make the visualization stronger. The electric motorcycle 100 is mainly applied to off-road scenes and mainly tends to the teenager market, and the vehicle information is amplified, so that a driver in the off-road scenes can quickly acquire vehicle information without needing to observe a display screen 191 with a smaller area, and meanwhile, a non-driver can quickly acquire relevant information of the vehicle from a visual lamp strip 192 to timely adjust driving states or the vehicle. For example, a guardian of a non-driver, particularly an underage driver, can timely acquire vehicle fault information and timely stop driving behaviors to perform corresponding maintenance and adjustment; and the vehicle electric quantity information can be acquired, and the vehicle electric quantity information can be returned to the charging area in time, so that the situation that the vehicle is thoroughly deficient in power and needs to be pushed to the charging area is avoided.

As an alternative embodiment, the seat cushion 123 is further provided with a shape substantially consistent with the shape of the light strip 192, and forms a smooth and integral outline of the light strip 192 with the appearance of the light strip 192, so that the light strip 192 can be visually prolonged, especially when the light strip 192 is in a non-working state, and the overall appearance of the electric motorcycle 100 can be greatly improved.

As shown in fig. 1, 11 and 12, the electric motorcycle 100 further includes a front baffle 126, and the front baffle 126 is at least partially disposed on the front side of the electric motorcycle 100. Specifically, the front baffle 126 is at least partially disposed in front of the battery assembly 14, and the front baffle 126 is also at least partially disposed at the front end of the upper plate 121 and forms a fixed connection with the upper plate 121.

The front baffle plates 126 are distributed on both left and right sides of the electric motorcycle 100 as viewed from the front-rear direction of the electric motorcycle 100, and further, the front baffle plates 126 are distributed on both ends of the head pipe 114, specifically, the front baffle plates 126 are disposed substantially bilaterally symmetrically with respect to the axis of the head pipe 114. The arrangement mode can effectively ensure that wind resistances born by two sides of the electric motorcycle 100 are basically the same, and avoid unstable running state of the vehicle caused by the wind resistances.

As shown in fig. 3 and 11 to 12, in order to preserve the heat dissipation performance of the front-end head-on intake air while protecting the components, a vent hole 1261 is provided in the front baffle 126, and it is understood that the vent hole 1261 is provided substantially symmetrically left and right along the axis of the head pipe 114. A lateral plane S3 is defined perpendicular to the lateral plane S3 of the front-rear direction of the electric motorcycle 100, and the distance of the lateral plane S3 to the rotation center of the front road wheel 161 is set to be substantially equal to the distance of the lateral plane S3 to the rotation center of the rear road wheel 162. As an alternative embodiment, the vent hole 1261 includes an air inlet hole 1261a and an air outlet hole 1261b, and as an alternative embodiment, the flow direction of the air in the air inlet hole 1261a is basically along the extending direction of the first straight line L1, the flow direction of the air in the air outlet hole 1261b is basically along the extending direction of the second straight line L2, and the projection of the first straight line on the reference plane along the up-down direction intersects with the projection of the second straight line on the reference plane along the up-down direction. Specifically, the inlet aperture 1261a extends substantially along the transverse plane S3 and the outlet aperture 1261b extends substantially along the longitudinal plane S2, i.e., an angle is formed between the plane in which the outlet aperture 1261b extends and the plane in which the outlet aperture 1261b extends. The air inlet hole 1261a and the air outlet hole 1261b are provided so as not to overlap when viewed in the front-rear direction of the electric motorcycle 100. This kind of setting mode can ensure from the front direction back view of electric motorcycle 100, can not see through ventilation hole 1261 direct observation inside electrical components and wire harness structure, not only can effectually make the outward appearance more superior, can also avoid simultaneously that mud and the sewage that splashes under the cross country scene get into electric motorcycle 100 inside through ventilation hole 1261, pollute inside components and parts. The air outlet hole 1261b is substantially disposed at one side of the air inlet hole 1261a near the longitudinal plane S2, that is, the air outlet holes 1261b of the air vents 1261 at the left and right sides are substantially disposed toward the inside of the electric motorcycle 100, that is, a cooling channel is formed between the air inlet hole 1261a and the air outlet hole 1261b, and the extending path of the cooling channel is disposed to at least partially penetrate the battery assembly 14. More specifically, the outlet aperture 1261b of the vent 1261 is disposed generally toward the battery assembly 14 and/or the harness connector, and the arrows in fig. 12 represent the air-cooled flow path. The sum of the areas of the inlet holes 1261a of the vent holes 1261 is defined as an inlet area S4, and the sum of the areas of the outlet holes 1261b is defined as an outlet area S5.
