During use, electric vehicle tire leakage is one of the common problems of electric vehicles. However, existing electric vehicles do not have tire pressure detection and warning dashboards, and cannot provide accurate feedback on the status of tire pressure, which can easily cause traffic hazards and tire blowouts.

[0003] In view of the above problems, regarding the technical problem that the existing electric vehicles do not have a tire pressure detection and warning instrument panel, after a lot of searches, the patent announcement number CN215851648U is found to be an electric vehicle instrument panel with tire pressure detection, including a cover, a dashboard panel is arranged inside, including a red display light, a red display light is arranged on one side of the dashboard panel, a green display light is arranged directly below the red display light, a yellow display light is arranged directly below the green display light, a pressure display meter is arranged above the red display light, and a buzzer is arranged above the pressure display meter. The red display light can remind that the tire pressure is insufficient, the green display light can remind that the tire pressure is within the normal range, and the yellow display light can remind that the tire pressure is too high when it is on. The side-by-side setting can fully display the tire pressure status of the front and rear wheels, and the pressure display meter can display the high and low pressure values ​​of the front and rear wheels for data display, so that the rider can understand the pressure value more intuitively. The buzzer can give a voice alarm when the red display light and the yellow display light are on, and remind the rider to understand the tire pressure status.
