Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive piping assembly with a multifunctional quick-connect connector. Background Technology

[0002] The multi-functional quick-connect automotive piping assembly is an automotive piping assembly that includes rubber hoses and plastic hose connectors. Its main purpose is to connect the engine and radiator, circulating coolant to the engine and transmitting real-time fluid temperature information to the vehicle's computer system via sensors. Existing automotive piping assemblies assemble quick-connect connectors and sensors separately, with sensors inserted in the middle of sections of the hose. This requires additional plastic molds, two clamps, and additional assembly steps, increasing the risk of leakage and raising production costs and quality risks. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multifunctional quick-connect connector for automotive piping assemblies that integrates the quick-connect connector and the sensor into a single structure, wherein the quick-connect connector body is derived from the sensor base and the sensor body is directly inserted into the quick-connect connector base, thereby reducing plastic molds, eliminating the need for segmentation of the hose, and reducing the risk of leakage.

[0004] The technical solution of this utility model is to provide a multifunctional quick-connect automotive piping assembly with the following structure: a first pipe and a second pipe; the first pipe has a first connector and a second connector at both ends; the second pipe has a third connector and a fourth connector at both ends; the second pipe is longer than the first pipe, and the section of the first pipe on which the second connector is installed is parallel to the section of the second pipe on which the fourth connector is installed, and the second connector and the fourth connector are integrally formed; both the first pipe and the second pipe are curved structures, and a first buckle is provided at their closest proximity; a temperature sensor is provided on the first connector, the housing of the temperature sensor is detachably connected to the first connector, the sensing end of the temperature sensor is located inside the first connector, and it is used to sense the temperature of the engine coolant inside the first connector; the temperature sensor transmits the sensed temperature signal to the vehicle controller.

[0005] The first connector is a bent pipe structure, including a first connecting pipe and a second connecting pipe. The first connecting pipe is perpendicular to the second connecting pipe and is the medium inlet. The second connecting pipe is provided with a third connecting pipe, which is perpendicular to the second connecting pipe. The temperature sensor is detachably connected to the end of the third connecting pipe and the two are connected by a sealing structure. The sensing end of the temperature sensor passes through the third connecting pipe and is inserted into the second connecting pipe.

[0006] The detachable connection between the temperature sensor and the end of the third connecting pipe means that the end of the third connecting pipe is provided with an annular protrusion, the annular protrusion is provided with an arc-shaped hole arranged radially, and a U-shaped retaining spring is connected in the arc-shaped hole. The two elastic rods of the U-shaped retaining spring pass through the arc-shaped hole and abut against the groove of the outer shell of the temperature sensor to lock and position it.

[0007] The third connector has a first positioning plate on its side, and the first positioning plate has a positioning notch.

[0008] The fourth connector has a second positioning plate on its side, and the second positioning plate has positioning holes.

[0009] The first connector, the second connector, the third connector, and the fourth connector are all clamped to the pipe fittings using pipe clamps.

[0010] With the above structure, this utility model has the following advantages: 1. Due to the structure of providing a temperature sensor on the first connector, that is, integrating the first connector and the temperature sensor into one piece, the main body of the first connector derives into the temperature sensor base, and the sensor body is directly inserted into the quick-connect connector base and fixed with a stainless steel retaining ring. Compared with the original product, it reduces plastic molds, eliminates the need for segmentation of the hose, reduces the risk of leakage, and eliminates the need for sensor base and clamp fasteners, reducing processing steps and lowering production costs and quality risks. 2. Since the housing of the temperature sensor is detachably connected to the first connector, and the sensing end of the temperature sensor is located inside the first connector, it is used to sense the temperature of the engine coolant inside the first connector. The temperature sensor transmits the sensed temperature signal to the vehicle controller, facilitating subsequent replacement of the temperature sensor. At the same time, the sensing end of the sensor is located inside the first connector, enabling instantaneous sensing of the coolant temperature inside the first connector and the first pipe.
