Automobile high-end sealing connection structure

Abstract

The invention discloses an automobile high-end sealing connection structure which comprises a sensing end, a contact sealing sleeve seat and a thermal expansion kick mechanism, the outer side of the sensing end is fixedly sleeved with a joint sleeve seat, and the contact sealing sleeve seat is fixed to the top end of the sensing end by being in threaded connection with the joint sleeve seat. A thermal expansion kick mechanism is fixedly installed in the contact sealing sleeve seat, a sealing wire rod is fixed to the inner cavity of the contact sealing sleeve seat and the top end of the sensing end in a press fit mode, and a contact end row is arranged on one side of the contact sealing sleeve seat. According to the invention, the split type sealing structure is arranged, and the sensing end and the contact sealing sleeve seat are connected and sealed by using the quick-release threaded pieces of the sensing end and the contact sealing sleeve seat, so that the sensor is more efficient and convenient to install, replace and maintain, and the sensor and the control panel group do not need to be integrally exposed in a monitoring environment; and the water vapor erosion of all the sensors is avoided, and the service life of the sensing assembly is prolonged.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automotive high-end sealing connection structure. Background technique [0002] In the car, there are various types of sensors to monitor various indicators of the car's operation. Therefore, it is of great significance for the safety, lifespan, energy saving and environmental protection of the car to maintain the stable operation performance of the sensor all the time. In order to ensure that the sensor can work safely and stably, the sensor generally needs to have the performance to avoid being affected by the environment, such as having a certain level of waterproof and sealing performance. When the sensor is working, it will be accompanied by the continuous change of the gas pressure. If the seal is not good, the problem of siphon water intake will easily occur. [0003] Existing sensors for monitoring automobile operation include sensors for measuring various fluid t...

Problems solved by technology

When the sensor is working, it will be accompanied by constant changes in gas pressure. If the seal is not good, the problem of siphon water ingress will easily occur

[0003] Existing sensors for monitoring automobile operation include sensors for measuring various fluid temperatures and pressures (such as intake air temperature, airway pressure, cooling water temperature and fuel injection pressure, etc.); sensors for determining the speed and position of various parts (such as vehicle speed , throttle opening, camshaft, crankshaft, transmission angle and speed, exhaust gas recirculation valve (EGR) position, etc.); there are also sensors for measuring engine load, knock, misfire and oxygen content in exhaust gas ; sensors to determine seat position; sensors to measure wheel speed, road height difference and tire pressure in anti-lock braking systems and suspension controls; Sensors and various sensor components are directly fixed in the monitoring environment in the form of electrode welding. Due to the harsh environment during operation, water vapor or oil stains are very easy to corrode the connection terminals of the sensor, which may cause poor contact or breakage of the connection terminals during long-term use. problems, and the way of direct welding and fixing, the installation and maintenance workload is heavy, and the maintenance cost of the car is increased, which has certain limitations
