Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a hydraulic control device for a heat dissipation electric vehicle. Background technique [0002] With the continuous development of science, technology and economy, automobiles have become an irreplaceable means of transportation in production and life. The popularity of automobiles also makes people have higher and higher requirements for the comfort of vehicles. [0003] In recent years, electric vehicles, as an important part of the practice of the concept of green environmental protection, have been vigorously promoted, and the number of electric vehicles has also increased year by year. There is a large room for improvement, and the technology of electric vehicles is also valued and actively developed by researchers. [0004] In the electric vehicle braking system of the prior art, a solenoid valve is used to control the on-off of the fluid to the braking system. [0005]...

AI Technical Summary

Problems solved by technology

[0008] 1. The solenoid valve refrigeration of the prior art needs to set up a refrigeration cavity, and process a refrigeration channel on the shell, but this belongs to micromachining, and the processing and manufacturing cost is relatively high

[0009] 1. In the electric vehicle braking system of the prior art, there will be a solenoid valve to control the on-off of the hydraulic chamber. However, this on-off cannot realize multi-mode adjustment, for example, the linear adjustment of the flow rate cannot be realized.

[0010] , Solenoid valves in the prior art have the requirement of fast opening, but the common way is to increase the power, and the solution is relatively simple

[0011] 1. The solenoid valve in the prior art will maintain power consumption when it is turned on. The common solution is to use a magnet, but there is no other solution.
