Description

technical field [0001] The invention relates to the field of cable related equipment, the international classification number is H01, in particular to a vehicle equipment with a junction box. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of technological level, the proportion of vehicles in people's life is getting higher and higher. The vehicle integrates various technologies such as electromechanical hydraulics, including fluid control, power transmission, exhaust gas treatment and other technologies; among them, the fluid control equipment controls the fluid system inside the vehicle, and cables are collectively referred to as optical cables, cables and other items. There are many uses for cables, mainly used for multiple functions such as control installation, connection equipment, and power transmission. The urea pump is an important part of the urea solution injection metering system. Its main function i...

AI Technical Summary

Problems solved by technology

[0004] 1. In the vehicle-mounted system of the prior art, the urea pump system is included to process the exhaust gas, and the fluid output from the urea pump is controlled by a solenoid valve to open and close. At the same time, there are various sensors for sensing. At this time, there are many wiring harnesses correspondingly. Harnesses can easily become tangled if left unchecked

[0005] 2. The medium in the urea tank for vehicles in the prior art is prone to freezing in winter, resulting in failure to work normally in time. The solution includes heating and thawing

However, there are some working conditions, such as semi-fluid and semi-frozen conditions when partly frozen, and for example, the case where there is no time to thaw after heating. At this time, if the solenoid valve is opened and a small amount of fluid flows through, the small amount of fluid at this time cannot satisfy normal work. , the greater possibility is that a small amount of fluid is too rare or dispersed during the flow process, resulting in the formation of an ice film, so a certain amount of fluid needs to flow after converging in order to work normally

[0006] 3. The flow control mechanisms in the prior art are all active devices to control the flow, but lack of means of automatic control

[0007] 4. The temperature-sensitive materials in the prior art only have the basic function of expansion and contraction, but due to their material limitations, more complex functions cannot be realized

[0008] 5. In the existing technology, if there are too many designs in the valve body, it is often difficult to process due to internal processing.
