New energy automobile electronic throttle valve structure

Abstract

The invention provides a new energy automobile electronic throttle valve structure applied to the technical field of new energy automobile parts. The new energy automobile electronic throttle valve structure is characterized in that a throttle valve air channel (2) is arranged on a shell body (1), wherein a rotating shaft (3) is mounted in the shell body (1), a valve plate (4) is mounted on the rotating shaft (3), and a motor (5) is further mounted in the shell body(1); and a rotating shaft gear (6) of the motor (5) meshes with an intermediate gear (7), wherein the intermediate gear (7) mesheswith a rotating shaft gear (8) on the rotating shaft (3), and a sealing ring (9) is arranged in the throttle valve air channel (2). According to the new energy automobile electronic throttle valve structure, gas flow can be accurately adjusted, and it is ensured that a new energy fuel automobile engine works under optimal working condition all the time, energy consumption is effectively reduced,and meanwhile gas flowing can be completely cut off after power failure, so that good sealing of a valve plate is achieved, and unnecessary power generation of a fuel cell stack is prevented; and in addition, a valve has the ice breaking capacity and can adapt to the severe environment.

Description

technical field [0001] The invention belongs to the technical field of new energy automobile parts, and more specifically relates to an electronic throttle structure of a new energy automobile. Background technique [0002] With the increasingly serious problem of energy shortage and environmental pollution, the automobile industry is developing towards low-emission and high-efficiency battery-driven or non-fuel-driven new energy sources. This type of new energy fuel technology has particularly high requirements on gas flow control and sealing performance. At present, the sealing performance and position accuracy of throttle valves on the market are generally not very high, which cannot guarantee the driving safety of new energy fuel vehicles and meet the requirements of low energy consumption. In the structure of the prior art, the design of the valve plate belongs to a single eccentric butterfly valve. When working, the valve plate will repeatedly squeeze the specific par...

Problems solved by technology

At present, the sealing performance and position accuracy of throttle valves in the market are generally not very high, which cannot guarantee the driving safety of new energy fuel vehicles and meet the requirements of low energy consumption.

In the structure of the prior art, the design of the valve plate belongs to a single eccentric butterfly valve. When it is working, the valve plate will repeatedly squeeze the specific part of the sealing ring, causing the sealing ring to wear and cause poor sealing.
