Abstract
Description
Technical Field
[0001] This application relates to the field of sensor technology, and in particular to a multi-performance detection sensor for vehicles. Background Technology
[0002] In the overall control system of a car, both electrical and non-electrical components play equally important roles. If the electrical components cannot be well controlled during vehicle operation, problems can easily occur. Similarly, problems with the non-electrical components (engine) can also affect driving safety. Generally speaking, the battery level sensor is used to detect the status of the electrical components during vehicle operation, while the oxygen sensor is a key component for controlling vehicle exhaust emissions, reducing environmental pollution, and improving the quality of fuel combustion in the engine. Specifically, the oxygen sensor detects the oxygen content in the engine exhaust. Based on the different percentages of oxygen on both sides of the sensor, a voltage change is generated across the sensor, and a corresponding voltage signal is sent to the electronic control unit (ECU). This reflects the oxygen percentage in the air-fuel mixture, and the ECU will accordingly control the fuel injection and air intake to ensure the engine operates at the optimal air-fuel mixture ratio, thus creating ideal conditions for the exhaust gas treatment of the three-way catalytic converter.
[0003] Existing oxygen sensors only have the function of detecting exhaust gas data and engine intake data. However, in special environments, such as sandstorm weather, they cannot adaptively adjust the oxygen supply, resulting in unknown engine efficiency. In this case, the electrical sensor can only detect the electrical components and cannot easily know the working status of the non-electrical components (engine).
[0004] In summary, the applicant believes that the existing technology has the limitation of only being able to perform single-function detection and being unable to perform in-depth detection under special weather conditions. Summary of the Invention
[0005] To address the aforementioned technical problems, this application provides a multi-performance detection sensor for vehicles.
[0006] This application provides a multi-performance detection sensor for vehicles, which adopts the following technical solution:
[0007] A multi-performance sensor for vehicles includes an oxygen content detection sensor and a battery level detection sensor disposed in the engine intake manifold. The oxygen content detection sensor includes a sleeve assembly, an airflow regulation 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 regulation assembly can adaptively adjust the air intake in the middle of the engine intake manifold based on the content of gravel in the incoming air. A second sensor detection end is disposed at the exhaust end. The oxygen content detection sensor also includes a processor. Both the first and second sensor detection ends are connected to the processor to transmit values to the processor.
[0008] By adopting the above technical solution, when a vehicle passes through an area with a lot of sand and dust during operation, the oxygen supply will be reduced in sandy weather. At this time, it is necessary to increase the air supply so that the engine can burn completely. The airflow adjustment component set in this solution can adaptively adjust the air supply according to the sand and gravel in the sand and dust. The first sensor can detect the oxygen content in the air supply of the engine, and the second sensor can detect the oxygen content in the exhaust gas. Finally, the processor calculates the working efficiency of the engine in a specific time period. This method is less affected by air quality. When the calculation results differ greatly, it is easier to find the engine fault, enabling in-depth detection in special weather conditions.
[0009] Preferably, the airflow regulating component includes a ventilation module and a regulating module disposed within the sleeve assembly. The regulating module includes an airflow regulating chamber and an airflow regulating plate disposed within the airflow regulating chamber. The airflow regulating plate includes a first regulating plate fixedly connected to the airflow regulating chamber and a second regulating plate slidably connected to the first regulating plate. The first regulating plate and the second regulating plate are provided with staggered air ducts.
[0010] By adopting the above technical solution, the air supply can be adjusted according to the size of the gap formed by the misalignment between the first and second adjustment plates. When there is sandstorm weather, it is necessary to strengthen the air supply. At this time, the gap between the two plates can be increased. This setting makes it easy to adjust.
[0011] Preferably, the ventilation module includes an auxiliary pipe sleeved on the outside of the sleeve assembly, forming a diversion channel between the auxiliary pipe and the sleeve assembly. A partition plate is provided 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 pipe. An elastic reset member is provided in the auxiliary pipe to drive the second adjusting plate to move upward. An external discharge pipe is provided on the lower side of the auxiliary pipe. A flow collector is provided on the lower side of the second adjusting plate. The flow collector is located in the external discharge pipe, and a gap is left between the flow collector and the external discharge pipe.
[0012] By adopting the above technical solution, when sandstorms occur, the first and second regulating plates can block some sand and gravel from passing through, but the corresponding air supply will also be reduced. At this time, some airflow will be blown to the collector plate through the diversion channel, and the collector plate will drive the second regulating plate to move downward. At this time, the channel formed between the first and second regulating plates will expand, thereby increasing the air feed and achieving adaptive adjustment.
[0013] Preferably, a vibration adjustment plate is fixed on the auxiliary pipeline at the position corresponding to the manifold, and the vibration adjustment plate can oscillate periodically.
[0014] By adopting the above technical solution, and by setting up a vibration adjustment plate, the vibration adjustment plate oscillates periodically, allowing the airflow to either blow onto the collector plate or not, so that the second adjustment plate can continuously move upward or downward, thereby producing a vibration effect. This can vibrate the sand and gravel on the first and second adjustment plates down, improving the ventilation effect.
[0015] Preferably, the connection between the second adjusting plate and the sleeve assembly is provided with an arc-shaped structure.
[0016] Preferably, the air inlet of the sleeve assembly is provided with an opening, and a baffle assembly is hinged at the opening; the tip of the baffle assembly faces the air inlet of the sleeve assembly and can rotate freely.
[0017] By adopting the above technical solution, the turbulence component can swing freely. When the gap between the first and second adjustment plates blocks the passage of gravel, the airflow will pass through the diversion channel. At this time, the airflow in the diversion channel will be driven to apply pressure towards the center, causing the turbulence component to move inward to form a conical nozzle. This setting can blow away the gravel on the first and second adjustment plates to a certain extent, providing air supply to the engine.
[0018] Preferably, the turbulence component has a hollow structure and an air inlet is provided on the turbulence component.
[0019] By adopting the above technical solution, the turbulence component is lighter and easier to rotate under the influence of airflow.
[0020] Preferably, a limiting piece is provided on the inner side of the sleeve assembly corresponding to the position of the turbulence component, and the limiting piece can abut against the turbulence component to restrict its rotation.
[0021] Preferably, the auxiliary pipeline is divided into an upper pipeline and a lower pipeline. The upper pipeline is equipped with an upper feed regulating plate to adjust the ventilation volume of the upper pipeline, and the lower pipeline is equipped with a lower feed regulating plate to adjust the ventilation volume of the lower pipeline.
[0022] By adopting the above technical solution, and by setting up an upper feed adjustment plate and a lower feed adjustment plate, the air volume of the upper flow channel and the lower flow channel can be adjusted, thereby making the formed blowhole higher or lower, improving the technical effect of blowing away the sand and gravel on the first adjustment plate and the second adjustment plate.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When a vehicle is traveling through an area with a lot of sand and dust, the oxygen supply will be reduced in sandy weather. At this time, it is necessary to increase the air supply so that the engine can burn more completely. The airflow adjustment component set in this solution can adaptively adjust the air supply according to the sand and gravel in the sand and dust. The first sensor can detect the oxygen content in the air supply of the engine, and the second sensor can detect the oxygen content in the exhaust gas. Finally, the processor calculates the working efficiency of the engine in a specific time period. This method is less affected by air quality. When the calculation results are significantly different, it is easy to find out the engine fault.
[0025] 2. By setting up an upper feed adjustment plate and a lower feed adjustment plate, the air volume of the upper and lower flow channels can be adjusted, thereby making the formed blowhole higher or lower, improving the technical effect of blowing away the sand and gravel on the first and second adjustment plates.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a multi-performance detection sensor for vehicles, referring to... Figure 1 and Figure 2 The system includes an oxygen content detection sensor and a power detection sensor installed in the engine intake manifold. The oxygen content detection sensor includes a sleeve assembly 1, an airflow regulating assembly 2 located at the front end of the sleeve assembly 1, a first sensor detection end 3 located at the end of the sleeve assembly 1, and a second sensor detection end located at the exhaust end of the vehicle. The first sensor detection end 3 is used to detect the oxygen content in the engine intake manifold, and the second sensor detection end is used to detect the oxygen content in the exhaust gas. A processor 4 is connected to the first sensor detection end 3 and the second sensor detection end. The processor 4 can calculate 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, thereby determining the engine's operating efficiency.
[0032] Reference Figure 2 and Figure 3 The airflow regulating component 2 includes a ventilation module 21 and an regulating module 22 disposed within the sleeve assembly 1. The regulating module 22 includes an airflow regulating chamber 221 and an airflow regulating plate disposed within the airflow regulating chamber 221. The airflow regulating plate can regulate the amount of air entering the engine. The airflow regulating plate includes a first regulating plate 222 fixedly connected to the airflow regulating chamber 221 and a second regulating plate 223 slidably connected to the first regulating plate 222. The first regulating plate 222 and the second regulating plate 223 are provided with staggered air ducts 224. When the first regulating plate 222 and the second regulating plate 223 are staggered, the ventilation volume can be increased or decreased.
[0033] The ventilation module 21 includes an auxiliary pipe 211 sleeved on the outside of the sleeve assembly 1. A diversion channel 212 is formed between the auxiliary pipe 211 and the sleeve assembly 1. A partition plate 213 is provided at the end of the diversion channel 212. The partition plate 213 is located between the first adjusting plate 222 and the second adjusting plate 223. The bottom of the second adjusting plate 223 can slide downward into the auxiliary pipe 211. An elastic reset member 214 is provided in the auxiliary pipe 211 to drive the second adjusting plate 223 upward. The elastic reset member 214 is a spring or elastic rubber. The auxiliary pipe 211 is provided with an external discharge pipe 216 on its lower side, the opening of which is located outside the vehicle body and faces the rear. The second adjusting plate 223 is provided with a collector plate 215 on its lower side, which is located inside the external discharge pipe 216 and has a gap between it and the external discharge pipe 216. A vibration adjusting plate 217 is fixed on the auxiliary pipe 211 at the position corresponding to the collector plate 215, and the vibration adjusting plate 217 can swing periodically. An arc-angle structure 11 is provided at the connection between the second adjusting plate 223 and the sleeve assembly 1.
[0034] When sandstorms occur, the first regulating plate 222 and the second regulating plate 223 can initially block some sand and gravel from passing through, but the corresponding air supply will also decrease. At this time, some airflow will be blown onto the collector plate 215 through the diverting channel 212. The collector plate 215 will then drive the second regulating plate 223 to move downwards. At this time, the channel formed between the first regulating plate 222 and the second regulating plate 223 will expand, thereby increasing the air feed. When there is a lot of sand and gravel on the first regulating plate 222 and the second regulating plate 223, the vibrating regulating plate 217 will... The periodic oscillation allows the airflow to either reach the collector plate 215 or not. When the airflow does not reach the collector plate 215, the second adjusting plate 223 will move upward under the action of the elastic reset member 214. When the airflow reaches the collector plate 215, the second adjusting plate 223 will move downward under the influence of the collector plate 215. The periodic movement of the vibration adjusting plate 217 can control the second adjusting plate 223 to move continuously upward or downward, thereby producing a vibration effect, which can vibrate the gravel on the first adjusting plate 222 and the second adjusting plate 223.
[0035] The air inlet of the sleeve assembly 1 has an opening, and a baffle assembly 12 is hinged at the opening. The baffle assembly 12 consists of two triangular prisms respectively located on the upper and lower sides of the sleeve assembly 1. Two of the inclined surfaces of the triangular prisms are longer, and the bottom end is shorter. The tips of the triangular prisms face the air inlet of the sleeve assembly 1 and can rotate freely. The rotation axis of the triangular prisms is located at the tip position. At this time, the tail end of the triangular prism can swing up or down. When the upper triangular prism moves downward and the lower triangular prism moves upward, it controls the concentration of air passing through the inside of the sleeve assembly 1, thereby facilitating the blowing off of gravel on the first adjusting plate 222 and the second adjusting plate 223. The baffle assembly 12 has a hollow structure. The turbulence-disrupting component 12 is relatively lightweight, making it easy to control its oscillation under the influence of airflow. An air inlet is provided on the turbulence-disrupting component 12. A limiting piece 13 is provided on the inner side of the sleeve assembly 1 corresponding to the position of the turbulence-disrupting component 12. The limiting piece 13 can abut against the turbulence-disrupting component 12 to limit its rotation. The auxiliary pipeline 211 is divided into an upper pipeline and a lower pipeline. An upper feed regulating plate 2111 is provided on the upper pipeline to adjust the ventilation volume of the upper pipeline, and a lower feed regulating plate 2112 is provided on the lower pipeline to adjust the ventilation volume of the lower pipeline. The upper feed regulating plate 2111 can slide relative to the upper pipeline, and the lower feed regulating plate 2112 can slide relative to the lower pipeline. The driving method can be a cylinder.
[0036] The working principle of a multi-performance vehicle sensor in this application is as follows: When sandstorms occur, the first adjusting plate 222 and the second adjusting plate 223 can block some sand and gravel from passing through, but the corresponding air supply will also be reduced. At this time, some airflow will be blown onto the collector plate 215 through the diverting channel 212. The collector 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 be expanded, thereby increasing the air supply. When there is a lot of sand and gravel on the first adjusting plate 222 and the second adjusting plate 223, a drive motor is provided on the vibration adjusting plate 217. The drive motor can drive the vibration adjusting plate 217 to swing, so that the airflow can be blown onto the collector plate 215 or... When the airflow is not directed towards the collector plate 215, the second adjusting plate 223 will move upward under the action of the elastic reset member 214. When the airflow is directed towards the collector plate 215, the second adjusting plate 223 will move downward under the influence of the collector plate 215. The periodic movement of the vibration adjusting plate 217 can control the second adjusting plate 223 to move continuously upward or downward, thereby producing a vibration effect, which can vibrate the 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 airflow through the sleeve assembly 1 to concentrate, thereby facilitating the blowing off of the gravel on the first adjusting plate 222 and the second adjusting plate 223. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
