[0002] Electric vehicles are electric-driven vehicles, also known as electric-driven vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as energy sources, and use controllers, motors and other components to convert electrical energy into mechanical energy to move, and control the current size to change the speed of the vehicle. In people's daily lives, the main electric vehicles include electric vehicles and battery vehicles. Battery vehicles have good convenience. In order to facilitate drivers to observe the status of battery vehicles, they are equipped with special dashboards on the vehicle body to display the power and speed.
[0003] However, when the existing electric vehicle instrument panel is in use, the sealing method of the electric vehicle instrument panel is relatively simple, and a single layer of rubber strip or sealant is mostly provided on the periphery of the instrument panel. As a result, in actual use, the vehicle is inevitably bumpy during driving, and the instrument panel is easily loosened and gaps are generated over a long period of time, thereby causing gaps in the rubber strip or sealant. Then, rainy days will cause rainwater to penetrate into the electric vehicle instrument panel, and the rainwater will cause damage to the electrical components inside the electric vehicle instrument panel, affecting the use of the electric vehicle instrument panel. Therefore, an electric vehicle instrument panel with multiple sealing and waterproofing is proposed to solve the above problems. Summary of the invention

[0007] Preferably, an annular sealing ring is provided at the bottom of the annular airbag, and an annular sealing groove 2 is formed on the bottom surface of the annular sealing groove 1 in cooperation with the annular sealing ring.
[0008] Preferably, the annular sealing ring and the annular airbag are both made of flexible rubber material.
[0009] Preferably, a plurality of water outlet holes are evenly opened on an outer wall of the annular sealing groove, and the bottom of the water outlet holes coincides with a bottom surface of the annular sealing groove.
[0010] Preferably, the waterproof strip is ring-shaped and is made of elastic rubber material.
[0011] Preferably, an observation window is provided on the top surface of the shell cover, and matching glass or transparent plastic is inlaid in the observation window.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0013] The utility model uses a waterproof strip to seal the connection between the shell and the shell cover, thereby realizing the first sealing and waterproofing of the electric vehicle instrument panel; by squeezing the annular airbag and overlapping and approaching the annular sealing groove, the sealing between the shell and the shell cover is improved, thereby realizing the second sealing and waterproofing of the electric vehicle instrument panel; by performing the first and second sealing and waterproofing of the shell and the shell cover, the sealing of the electric vehicle instrument panel is improved, external water is prevented from entering the electric vehicle instrument panel, the internal electrical components are protected, and the service life of the electric vehicle instrument panel is increased.
