Description

Technical Field

[0001] This application relates to the technical field of sensors, and in particular, to a vehicle multi-performance detection sensor. Background Art

[0002] In the overall control system of an automobile, the electrical part and the non-electrical part play equally important roles. If the electrical part cannot be well controlled during the driving of the automobile, problems are likely to occur in the vehicle. If there are problems with the non-electrical part (engine) during the driving of the automobile, it will also affect the driving safety. Generally speaking, the power detection sensor is used to detect the situation feedback of the electrical part during the driving of the automobile. The oxygen sensor is a key component for controlling vehicle exhaust emissions, reducing environmental pollution caused by the vehicle, and improving the fuel combustion quality of the vehicle engine. The oxygen sensor is used to detect the situation feedback of the non-electrical part during the driving of the automobile. Specifically, the oxygen sensor detects the oxygen content in the engine exhaust emissions. According to the different percentage contents of oxygen on both sides of the sensor, a voltage change is generated at both ends of the sensor, and a corresponding voltage signal is sent to the electronic control unit to reflect the high or low percentage content of oxygen in the air-fuel mixture. The ECU will correspondingly control the fuel injection volume and the intake air volume to make the engine operate in the state of the best air-fuel mixture ratio, thereby creating ideal conditions for the exhaust gas treatment of the subsequent three-way catalytic converter.

[0003] The existing oxygen sensor only has the functions of detecting exhaust gas data and engine intake end data. However, in special environments, such as in sandy weather, it cannot adaptively adjust the oxygen feed amount, resulting in an unknown working efficiency of the engine. At this time, only the power detection sensor can feedback the situation of the electrical part, and it is not easy to know the working condition of the non-electrical part (engine).

[0004] In summary, the applicant believes that the existing technology can only perform single detection and cannot perform in-depth detection in special weather conditions. Summary of the Invention

[0005] In order to solve the above technical problems, this application provides a vehicle multi-performance detection sensor.

[0006] A vehicle multi-performance detection sensor provided by this application adopts the following technical solutions: A multi-performance detection sensor for a vehicle includes an oxygen content detection sensor and a power detection sensor arranged in an engine intake pipe, the oxygen content detection sensor includes a sleeve assembly, an airflow adjustment assembly located at the front end of the sleeve assembly, and a first sensor detection end located at the end of the sleeve assembly; the airflow adjustment assembly can adaptively adjust the air feed amount in the middle of the engine intake pipe based on the content of grit in the incoming air of the engine intake pipe; a second sensor detection end is arranged at the exhaust end, the oxygen content detection sensor also includes a processor, and the first sensor detection end and the second sensor detection end are both connected to the processor to transmit numerical values ​​to the processor.

[0007] By adopting the above technical scheme, during the driving process of the vehicle, if it passes through an area with a lot of dust, the oxygen supply in the dusty weather will be weakened. At this time, the air supply needs to be increased so that the engine can fully burn and work. The airflow adjustment component set by this scheme can adaptively adjust the air supply according to the gravel situation in the dust, so that the first sensor detection end can detect the oxygen content in the air supply of the engine, and then detect the oxygen content of the exhaust gas through the second sensor detection end, and finally calculate the working efficiency of the engine in a specific time period through the processor. This method is less affected by air quality. When the calculation results are far apart, it is easy to derive the engine's fault condition, so that in-depth detection can be performed under special weather conditions.

[0008] Preferably, the airflow adjustment component includes a ventilation module and an adjustment module arranged in the sleeve assembly, the adjustment module includes an air volume adjustment chamber and an air volume adjustment plate arranged in the air volume adjustment chamber, the air volume adjustment plate includes a first adjustment plate fixedly connected to the air volume adjustment chamber and a second adjustment plate slidably connected to the first adjustment plate, and the first adjustment plate and the second adjustment plate are provided with staggered air ducts.

[0009] By adopting the above technical solution, the air supply amount is adjusted according to the size of the gap formed by the misalignment between the first adjustment plate and the second adjustment plate by setting the first adjustment plate and the second adjustment plate. When it is in dusty weather, the air supply needs to be strengthened. At this time, the gap between the two can be increased. This setting makes it convenient to adjust.

[0010] Preferably, the ventilation module includes an auxiliary pipeline sleeved outside the casing assembly. A diversion channel is formed between the auxiliary pipeline and the casing assembly. A partition plate is arranged at the end of the diversion channel, and the partition plate is located between the first adjusting plate and the second adjusting plate. The bottom of the second adjusting plate can slide downward into the auxiliary pipeline. An elastic resetting member for driving the second adjusting plate to move upward is arranged in the auxiliary pipeline. An external discharge pipeline is arranged on the lower side of the auxiliary pipeline. A flow collecting plate is arranged on the lower side of the second adjusting plate. The flow collecting plate is located in the external discharge pipeline, and a gap is left between the flow collecting plate and the external discharge pipeline.

[0011] By adopting the above technical solution, when a sandstorm occurs, firstly, the first adjusting plate and the second adjusting plate can block part of the gravel from passing through, but the corresponding air supply amount will also be weakened. At this time, part of the air flow will blow to the flow collecting plate through the diversion channel. The flow collecting plate will drive the second adjusting plate to move downward. At this time, the channel formed between the first adjusting plate and the second adjusting plate will expand, thereby increasing the air feed amount and realizing adaptive adjustment.

[0012] Preferably, a vibration adjusting plate is fixedly arranged on the auxiliary pipeline at a position corresponding to the flow collecting plate, and the vibration adjusting plate can swing periodically.

[0013] By adopting the above technical solution, by arranging the vibration adjusting plate which swings periodically, the air flow can blow to the flow collecting plate or not blow to the flow collecting plate, so that the second adjusting plate can move upward or downward continuously, thereby generating a vibration effect, and the gravel on the first adjusting plate and the second adjusting plate can be vibrated off, improving the ventilation effect.

[0014] Preferably, an arc angle structure is arranged at the connection between the second adjusting plate and the casing assembly.

[0015] Preferably, an opening is arranged at the air inlet of the casing assembly, and a flow disturbing assembly is hinged at the opening. The tip of the flow disturbing assembly faces the air inlet of the casing assembly and can rotate freely.

[0016] By adopting the above technical solution, the flow disturbing assembly can swing freely. When the gap between the first adjusting plate and the second adjusting plate blocks the gravel from passing through, the air flow will pass through the diversion channel. At this time, the air flow in the diversion channel will drive the pressure towards the middle, so that the flow disturbing assembly moves inwards to form a conical air blowing port. Through this setting scheme, the gravel on the first adjusting plate and the second adjusting plate can be blown off to a certain extent, providing the air supply effect for the engine.

[0017] Preferably, the flow disturbing assembly is of a hollow structure, and an air inlet is arranged on the flow disturbing assembly.

[0018] By adopting the above technical solution, the spoiler component is lighter and easier to rotate driven by the airflow.

[0019] Preferably, a limiting plate is provided on the inner side of the sleeve assembly at a position corresponding to the spoiler assembly, and the limiting plate can contact the spoiler assembly to limit its rotation.

[0020] Preferably, the auxiliary pipeline is divided into an upper pipeline and a lower pipeline, the upper pipeline is provided with an upper feed regulating plate for regulating the ventilation volume of the upper pipeline, and the lower pipeline is provided with a lower feed regulating plate for regulating the ventilation volume of the lower pipeline.

[0021] By adopting the above technical solution, by setting the upper feed adjustment plate and the lower feed adjustment plate, the air volume of the upper diversion channel and the lower diversion channel can be adjusted, so that the formed blowing port is biased upward or downward, thereby improving the technical effect of blowing off the sand on the first adjustment plate and the second adjustment plate.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the driving process of the vehicle, if it passes through an area with a lot of dust, the oxygen supply in the dusty weather will be weakened. At this time, the air supply needs to be increased so that the engine can fully burn and work. The airflow adjustment component set by this scheme can adaptively adjust the air supply according to the gravel situation in the dust, so that the first sensor detection end can detect the oxygen content in the air supply of the engine, and then detect the oxygen content of the exhaust gas through the second sensor detection end. Finally, the processor calculates the working efficiency of the engine in a specific time period. This method is less affected by air quality, and when the calculation results are far apart, it is easy to derive the engine failure situation.

[0023] 2. By setting the upper feed adjustment plate and the lower feed adjustment plate, the air volume of the upper diversion channel and the lower diversion channel can be adjusted, so that the formed blowing port is biased upward or downward, thereby improving the technical effect of blowing off the sand on the first adjustment plate and the second adjustment plate.

[0028] The following further describes the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0029] An embodiment of the present application discloses a multi-performance detection sensor for a vehicle. Referring to Figure 1 and Figure 2 , it includes an oxygen content detection sensor and an electric quantity detection sensor arranged in the engine intake pipe. The oxygen content detection sensor includes a sleeve assembly 1, an airflow regulating assembly 2 at the front end of the sleeve assembly 1, a first sensor detection end 3 at the end of the sleeve assembly 1, and a second sensor detection end at the vehicle exhaust end; the first sensor detection end 3 is used to detect the oxygen content at the engine intake pipe, and the second sensor detection end is used to detect the oxygen content of the exhaust gas. A processor 4 is connected to the first sensor detection end 3 and the second sensor detection end. The difference between the oxygen content detected by the first sensor detection end 3 and the oxygen content detected by the second sensor detection end can be calculated through the processor 4, and then the working efficiency of the engine can be judged.

[0030] Referring to Figure 2 and Figure 3 , the airflow regulating assembly 2 includes a ventilation module 21 and a regulation module 22 arranged in the sleeve assembly 1; the regulation module 22 includes an air volume regulating chamber 221 and an air volume regulating plate arranged in the air volume regulating chamber 221. The air volume regulating plate can adjust the amount of air entering the engine. The air volume regulating plate includes a first regulating plate 222 fixedly connected to the air volume regulating chamber 221 and a second regulating plate 223 slidably connected to the first regulating plate 222. Air ducts 224 are arranged on the first regulating plate 222 and the second regulating plate 223 in a staggered manner; when the first regulating plate 222 and the second regulating plate 223 are staggered, the ventilation volume can be increased or decreased.

[0031] The ventilation module 21 includes an auxiliary pipeline 211 sleeved outside the sleeve assembly 1. A diversion channel 212 is formed between the auxiliary pipeline 211 and the sleeve assembly 1. A partition plate 213 is provided at the end of the diversion channel 212, and the partition plate 213 is located between the first adjustment plate 222 and the second adjustment plate 223. The bottom of the second adjustment plate 223 can slide downward into the auxiliary pipeline 211. An elastic reset member 214 for driving the second adjustment plate 223 to move upward is provided in the auxiliary pipeline 211. The elastic reset member 214 is a spring or an elastic rubber block. An outer discharge pipeline 216 is provided on the lower side of the auxiliary pipeline 211, and the opening of the outer discharge pipeline 216 is located outside the vehicle body and faces the rear side. A flow collecting plate 215 is provided on the lower side of the second adjustment plate 223. The flow collecting plate 215 is located in the outer discharge pipeline 216, and a gap is left between the flow collecting plate 215 and the outer discharge pipeline 216. A vibration adjustment plate 217 is fixedly provided on the auxiliary pipeline 211 at the position corresponding to the flow collecting plate 215, and the vibration adjustment plate 217 can swing periodically. An arc angle structure 11 is provided at the connection between the second adjustment plate 223 and the sleeve assembly 1.

[0032] When there is a sandstorm, first, the first adjustment plate 222 and the second adjustment plate 223 can block part of the sand and gravel from passing through, but the corresponding air supply volume will also decrease. At this time, part of the air flow will blow to the flow collecting plate 215 through the diversion channel 212. The flow collecting plate 215 will drive the second adjustment plate 223 to move downward. At this time, the channel formed between the first adjustment plate 222 and the second adjustment plate 223 will expand, and thus the air feed volume can be increased. When there is more sand and gravel on the first adjustment plate 222 and the second adjustment plate 223, the vibration adjustment plate 217 swings periodically, so that the air flow can blow to the flow collecting plate 215 or not blow to the flow collecting plate 215. When it does not blow to the flow collecting plate 215, the second adjustment plate 223 will move upward under the action of the elastic reset member 214. When it blows to the flow collecting plate 215, the second adjustment plate 223 will move downward under the drive of the flow collecting plate 215. The periodic movement of the vibration adjustment plate 217 can control the second adjustment plate 223 to move up and down continuously, and thus produce a vibration effect, which can vibrate the sand and gravel on the first adjustment plate 222 and the second adjustment plate 223 off.

[0033] An air inlet of the sleeve assembly 1 is provided with an opening, and a flow disturbing assembly 12 is hinged at the opening; the flow disturbing assembly 12 is two triangular prisms respectively arranged on the upper and lower sides of the sleeve assembly 1. Two of the inclined surfaces of the triangular prism are longer and the bottom end is shorter. The tip of the triangular prism faces the air inlet of the sleeve assembly 1 and can rotate freely. The rotation axis of the triangular prism is located at the tip position. At this time, the tail end of the triangular prism can swing upward or downward. When the upper triangular prism moves downward and the lower triangular prism moves upward, it will control the concentration of the air passing through the inside of the sleeve assembly 1, thereby facilitating the blowing off of the grit on the first adjusting plate 222 and the second adjusting plate 223. The flow disturbing assembly 12 is a hollow structure, making the flow disturbing assembly 12 lighter and facilitating the control of the swing under the action of the air volume. An air inlet is provided on the flow disturbing assembly 12; a limiting piece 13 is arranged on the inner side of the sleeve assembly 1 corresponding to the position of the flow disturbing assembly 12, and the limiting piece 13 can abut against the flow disturbing assembly 12 to limit its rotation; the auxiliary pipeline 211 is divided into an upper pipeline and a lower pipeline. An upper feed adjusting plate 2111 for adjusting the air volume of the upper pipeline is arranged on the upper pipeline, and a lower feed adjusting plate 2112 for adjusting the air volume of the lower pipeline is arranged on the lower pipeline; the upper feed adjusting plate 2111 can slide relative to the upper pipeline, and the lower feed adjusting plate 2112 can slide relative to the lower pipeline. The driving method can be a cylinder.

[0034] The working principle of a vehicle multi-performance detection sensor in this application is as follows: When there is a sandy dust weather, first, the first adjusting plate 222 and the second adjusting plate 223 can block part of the sand and gravel from passing through, but the corresponding air supply volume will also be weakened. At this time, part of the air flow will be blown onto the current collecting plate 215 through the shunt channel 212. The current collecting plate 215 will drive the second adjusting plate 223 to move downward. At this time, the channel formed between the first adjusting plate 222 and the second adjusting plate 223 will expand, thereby increasing the air feed volume. When there is a lot of sand and gravel on the first adjusting plate 222 and the second adjusting plate 223, a driving motor is provided on the vibration adjusting plate 217. The driving motor can drive the vibration adjusting plate 217 to swing, so that the air flow can blow onto the current collecting plate 215 or not blow onto the current collecting plate 215. When it does not blow onto the current collecting plate 215, the second adjusting plate 223 will move upward under the action of the elastic reset member 214. When it blows onto the current collecting plate 215, the second adjusting plate 223 will move downward under the drive of the current collecting plate 215. The periodic movement of the vibration adjusting plate 217 can control the second adjusting plate 223 to continuously move upward or downward, thereby generating a vibration effect, which can vibrate the sand and gravel on the first adjusting plate 222 and the second adjusting plate 223; the tail end of the triangular prism can swing upward or downward. When the upper triangular prism moves downward and the lower triangular prism moves upward, it will control the air inside the sleeve assembly 1 to concentrate, thereby facilitating the blowing off of the sand and gravel on the first adjusting plate 222 and the second adjusting plate 223. The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
