Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to an automobile intelligent detection and diagnosis system. Background Art

[0002] The three-way catalytic converter is the most important off-board purification device installed in a vehicle's exhaust system. It converts harmful exhaust gases such as CO, HC, and NOx into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. When hot exhaust passes through the purification device, the purifier in the three-way catalytic converter enhances the activity of CO, HC, and NOx, prompting them to undergo a specific oxidation-reduction chemical reaction. At high temperatures, CO is oxidized to colorless, non-toxic carbon dioxide; HC compounds are oxidized to water (H2O) and carbon dioxide; and NOx is reduced to nitrogen and oxygen. These three harmful gases are converted into harmless gases, effectively purifying the exhaust.

[0003] During the driving process of smart cars, the three-way catalytic converter plays an important filtering role in the exhaust emissions of smart cars. However, the existing three-way catalytic converter will become clogged after long-term use, causing the car's power to decline and increased fuel consumption. Most users will only check and repair it when they feel obvious power shortage while driving. Failure to discover the problem in time will not only affect the performance of the engine, but also increase fuel consumption and increase the cost of use.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] Example 1:

[0039] This application discloses an intelligent automobile detection and diagnosis system. Figure 1, including revolution data, a controller, an electric push rod 12, a detection component, a data integration module, a big data comparison, and a screen warning. The revolution data is connected to the controller, the controller is connected to the electric push rod 12, the electric push rod 12 is connected to the detection component, the detection component and the revolution data are connected to the data integration module, the data integration module is connected to the big data comparison telecommunication, and the big data comparison is connected to the screen warning;

[0040] See also Figure 2-6 The detection component includes an exhaust pipe 1, an anti-wind tube 11 installed on the exhaust pipe 1, an electric push rod 12 installed on the upper end of the anti-wind tube 11, an anemometer 2 installed on the lower end of the electric push rod 12, and a sealing piece 4 installed on the lower end of the anemometer 2.

[0041] During use, when the engine speed reaches the set speed, the controller can control the electric push rod 12 to push the detection component, so that the detection component moves downward and the gas displacement discharged from the exhaust pipe 1 is detected. After the detection result is obtained, the data integration module is used to compare the data with the displacement at the same speed when the three-way catalytic converter of other cars is blocked. When the displacement is lower than the displacement at the same speed when the three-way catalytic converter of other cars is blocked, an early warning is issued through the screen to inform the user to replace and clean the three-way catalytic converter in time.

[0042] The anemometer 2 includes a housing 21, the lower end of the housing 21 is rotatably connected to the main rotating block 22, the lower side of the main rotating block 22 is provided with an auxiliary rotating block 23, a plurality of elastic rods 24 are provided on the auxiliary rotating block 23, a plurality of elastic rods 24 are provided with a wind pot 25 at one end away from the auxiliary rotating block 23, an annular air cavity 231 is excavated inside the auxiliary rotating block 23, an air pump 26 connected to the air cavity 231 is installed between the elastic rod 24 and the auxiliary rotating block 23, a piston 261 is slidably connected to the interior of the air pump 26, a pull rope 262 is fixedly connected to the interior of the elastic rod 24, and the pull rope 262 is connected to the piston 261 is fixedly connected, and two negative pressure cylinders 27 connected to the air cavity 231 are provided on the inner wall of the auxiliary rotating block 23. A movable plug 271 is slidably connected inside the negative pressure cylinder 27, and a plug rod 272 inserted into the main rotating block 22 is fixedly connected to the movable plug 271. Two elastic ropes 273 are fixedly connected between the movable plug 271 and the negative pressure cylinder 27. A detection shaft 3 is provided inside the outer shell 21, and a magnetic moving block 31 is slidably connected inside the detection shaft 3. The lower end of the magnetic moving block 31 is fixedly connected to a connecting rod 32, and the connecting rod 32 passes through the main rotating block 22 and is fixedly connected to the auxiliary rotating block 23.

[0043] See also Figure 7 , when there is carbon deposit on the detection component, such as Figure 7As shown, the main rotating block 22 cannot rotate or the rotation resistance increases. At this time, under the action of exhaust gas discharge, the wind pot 25 will be blown until the elastic rod 24 bends. The bending of the elastic rod 24 drives the pull rope 262 to deform and pull the piston 261 to move. The piston 261 sucks the gas inside the air cavity 231, and under the action of negative pressure, the moving plug 271 inside the negative pressure cylinder 27 moves, prompting the insertion rod 272 to separate from the main rotating block 22. At this time, the main rotating block 22 and the auxiliary rotating block 23 are released from the limit, so the auxiliary rotating block 23 falls downward, and then under the action of exhaust gas discharge, the auxiliary rotating block 23 rotates, and drives the detection shaft 3 to perform detection through the magnetic shift block 31, so as to avoid inaccurate detection due to carbon deposits attached to the detection component.

[0044] See also Figure 8-9 A plurality of liquid discharge cylinders 5 are provided on the side wall of the outer shell 21. The liquid discharge cylinder 5 includes a cylinder shell 51. A magnetic plug 52 is slidably connected to the inside of the cylinder shell 51 and is magnetically connected to the magnetic shift block 31. The inside of the cylinder shell 51 is filled with a cleaning agent 54. A one-way pipe 53 is connected between the cylinder shell 51 and the outer shell 21. The cleaning agent 54 is made of a volatile liquid with an odor and a detergent mixed in a ratio of 1:5.

[0045] At the same time, when the magnetic moving block 31 moves downward, it will attract the magnetic plug 52 to move, and then the cleaning agent 54 will be discharged from the one-way exhaust pipe 53 to the inside of the shell 21, dissolving the carbon deposits and achieving a certain auxiliary cleaning effect. In addition, when the exhaust gas is discharged, the cleaning agent 54 can also cause a certain degree of volatilization and produce an odor, thereby reminding the user to disassemble and clean the detection component in time, thereby improving the detection accuracy of the detection component.

[0046] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
