[0038] The present invention provides a schematic diagram of the overall structure of an implementation manner of an automobile exhaust gas sensor, including:

[0039] Please refer to Figures 1-8, An automotive exhaust gas sensor according to this embodiment includes a plug fixing block 1. An external protective sleeve 14 is provided outside the plug fixing block 1. A first fixing block 20 is fixedly connected to the surface of the external protective sleeve 14. A bundling ring 21 penetrates through the inside of the first fixing block 20. The penetration of the bundling ring 21 is inside a locking block 24. A misalignment block 22 is movably connected to the surface of the locking block 24. A lock catch 23 is fixedly connected to the side of the misalignment block 22. A second fixing block 25 is fixedly connected to the surface of the external protective sleeve 14. A connecting rod 26 is connected to the top of the second fixing block 25 through a rotating shaft. A magnetic attraction block 27 is fixedly connected to the side of the connecting rod 26. A magnetic attraction buckle 28 is magnetically connected to the bottom of the magnetic attraction block 27. By means of the bundling ring 21 penetrating through the inside of the first fixing block 20 and the second fixing block 25 fixedly connected to the external protective sleeve 14, the sensor line can be distinguished from other lines, preventing the detection of any misprocessed lines during inspection and achieving a bundling effect.

[0040] It should be noted that, in order to prevent dust from entering the inside of the plug fixing block 1 and the sensing module 6 when the automotive exhaust gas sensor is idle for a long time and causing it to malfunction when put into use. Specifically, the surface of the plug fixing block 1 can be installed inside an embedding groove 10. The embedding groove 10 is opened on the front surface of the front fixing block 9. A first installation ring 16 is opened on the front surface of the front fixing block 9. A front protective plate 17 can be installed inside the first installation ring 16. A rear fixing block 8 is provided behind the front fixing block 9. A second installation ring 18 is opened on the back surface of the rear fixing block 8. A rear protective plate 19 can be installed inside the second installation ring 18.

[0041] Subsequently, in order to conveniently connect the automotive exhaust gas sensor to the corresponding part of the vehicle. Specifically, a plug board 2 is fixedly connected to the front surface of the plug fixing block 1. A plug rod 3 is fixedly connected inside the plug board 2.

[0042] At the same time, in order to prevent the connecting wire 4 from being exposed outside and generating static electricity to damage the sensor. Specifically, one end of the connecting wire 4 is fixedly connected to the back surface of the front fixing block 9. The other end of the connecting wire 4 is fixedly connected to the front surface of the sensing module 6. An insulating outer skin 5 is provided on the surface of the connecting wire 4.

[0043] Furthermore, in order to facilitate the automotive exhaust gas sensor to conveniently detect the automotive exhaust gas part. Specifically, a rear fixing block 8 is fixedly connected to the surface of the sensing module 6. A sensing head 7 is fixedly connected to the back surface of the sensing module 6.

[0044] It should be noted that, in order to protect the normal use of the entire automotive exhaust gas sensor. Specifically, an internal protective sleeve 12 is fixedly connected to the surfaces of the internal fixing block and the rear fixing block 8. Internal heat dissipation holes 13 are opened on the surface of the internal protective sleeve 12.

[0045] It should be noted that in order to prevent the automotive exhaust gas sensor from malfunctioning due to excessive temperature in a high-load working environment, specifically, an external protective sleeve 14 is fixedly connected to the surface of the internal protective sleeve 12, and external heat dissipation holes 15 are formed on the surface of the external protective sleeve 14.

[0046] Finally, in order to facilitate understanding of the temperature fluctuations of the exhaust gas sensor during operation, specifically, a thermometer 11 is fixedly connected to the front surface of the front fixing block 9, and the front protective plate 17 and the rear protective plate 19 are made of transparent plastic material.

[0047] In addition, the circuits, electronic components, and modules involved in the present invention are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present invention does not involve improvements to the internal structure and method.

[0048] Combined Figures 1-8 , the specific usage process of an automotive exhaust gas sensor according to this embodiment is as follows:

[0049] 1: When using this type of automotive exhaust gas sensor, first, the front protective plate 17 and the rear protective plate 19 installed on the surfaces of the front fixing block 9 and the rear fixing block 8 through the first mounting ring 16 and the second mounting ring 18 need to be removed. The front protective plate 17 and the rear protective plate 19 can play a role in dust prevention, facilitating its normal use after the vehicle is turned on and reducing the risk of malfunction.

[0050] 2: Subsequently, the plug fixing block 1 can be fixed to the corresponding position of the vehicle. Through the internal plug rod 3 and the bow plate, the device can be connected to the corresponding position. Since it is a plug connection, it is also relatively convenient to disassemble or replace. At the same time, when the sensor needs to be stored for a long time, the front protective plate 17 and the rear protective plate 19 can be reinstalled through the first mounting ring 16 and the second mounting ring 18 for idle storage, with good preservation effect. At the same time, when the vehicle is running at high load, the efficiency of this automotive exhaust gas sensor will also be improved accordingly. When running at high load, the sensing module 6 may generate heat, and there may be a risk of malfunction of the sensing module 6 under long-term high-load operation. Heat can be dissipated to the outside through the internal heat dissipation holes 13 and the external heat dissipation holes 15 formed on the surfaces of the internal protective sleeve 12 and the external protective sleeve 14, so that the automotive exhaust gas sensor is not easily malfunctioned due to the increase of internal temperature during use, and the heat dissipation effect is good.

[0051] 3: When installing the automotive exhaust gas sensor, first insert the plug fixing block 1 into the corresponding position of the vehicle. Subsequently, the connecting wire 4 of other circuits can be pulled onto the surface of the outer protective sleeve 14 and tied up with the binding ring 21. Then, tighten the binding ring 21. Since the binding ring 21 passes through the locking block 24 and the dislocation block 22, at this time, by moving the dislocation block 22, the lock catch 23 on the side of the dislocation block 22 can be buckled inside another dislocation block 22. There are holes in the dislocation block 22 and the locking block 24 through which the binding ring 21 passes. When the dislocation block 22 moves towards the lock catch 23, the holes inside will gradually shrink due to the dislocation. Thus, the binding ring is clamped inside to play a role in fixing the binding ring 21. At the same time, a second fixing block 25 is fixedly connected to the surface of the outer protective sleeve 14. By the mutual magnetic attraction of the magnetic attraction block 27 and the magnetic attraction buckle 28, the connecting wire 4 of other circuits can be placed in the gap formed between the two second fixing blocks 25 and the connecting rod 26, which is convenient for collecting other wire harness structures outside the device. When maintenance personnel need to inspect and repair the sensor, it is not easy to misidentify the wrong wire due to the overly messy internal wires, which improves the inspection efficiency.

[0052] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
