Description

Technical Field

[0001] The utility model relates to the technical field of refueling metering, in particular to a refueling metering device for an automobile. Background Art

[0002] Currently, most vehicle fuel tanks lack fuel metering capabilities. Fuel gauges on vehicle dashboards only provide a rough estimate of the remaining fuel level, but cannot display the actual amount of fuel filled in real time. After each refueling session, only an approximate estimate of the fuel volume is available, making it impossible to verify the accuracy of the fuel volume displayed by the gas station's metering device. The dishonest behavior of some unscrupulous gas station operators can lead to discrepancies between actual fuel levels and displayed fuel levels, deceiving consumers. Consumers, however, have no other means of determining whether the fuel level meets the required standards, resulting in losses.

[0003] The development of automotive refueling metering technology is primarily reflected in the following aspects: Early mechanical metering systems used pulleys, float-type tanks, and other devices. While simple and easy to maintain, they were relatively inaccurate. Advances in electronics have led to the widespread use of electronic metering devices such as electromagnetic flowmeters, mass flowmeters, and positive displacement flowmeters, significantly improving accuracy and providing self-diagnosis and fault diagnosis capabilities. In recent years, the application of the Internet of Things, big data, and artificial intelligence technologies has enabled the emergence of intelligent refueling metering systems. These systems monitor fuel flow in real time, automatically record data, and connect to back-end management systems via wireless communication to provide data analysis and early warning services. Furthermore, increasingly stringent environmental regulations have driven the development of fuel evaporation control systems to reduce fuel and vapor emissions during refueling. To enhance safety, anti-tampering technologies, encrypted payment systems, and video surveillance systems are also being increasingly implemented at gas stations. Overall, automotive refueling metering technology is evolving towards high precision, intelligence, environmental friendliness, and safety to meet stricter industry standards and diverse consumer demands.

[0004] A Chinese patent application with publication number "CN208653559U" discloses a vehicle refueling recorder. The specification states that the recorder is installed at the fuel tank filler port of a vehicle. An ultrasonic flow sensor is installed inside the filler port, and an electronic control unit and a display are installed outside the filler port. The ultrasonic flow sensor and the electronic control unit are connected via a signal cable, and the electronic control unit is also connected to the display via a signal cable. The recorder, installed at the fuel tank filler port, can display and record each fuel refill in real time.

[0005] The existing patent with publication number "CN207317880U" discloses an automobile refueling metering device. According to the content recorded in the specification, the device includes a cylindrical body that can be fixed in the connection pipe between the refueling hole and the oil tank. The top of the cylinder is covered with an upper cover body with a central oil gun hole. The bottom of the cylinder is covered with a lower cover body with a flow metering mechanism. A flow signal transmission mechanism is provided between the flow metering mechanism and the display mechanism. The automobile refueling metering device can effectively detect the flow of gasoline added to the automobile oil tank.

[0006] The existing Chinese patent document application file with publication number "CN219810500U" discloses a refueling metering and detection equipment. According to the content recorded in the specification, the fixed pipe bottom of the device is provided with a metering assembly for refueling metering. The fixed pipe bottom is fixedly connected with a metering pipe for installing the metering assembly. The surface of the fixed pipe and the cover plate is provided with a rubber ring for improving the sealing performance. The fixed pipe is fixedly connected with a fixing assembly inside the pipe. The metering assembly is provided with multiple vortex fans for detecting flow rate. The data is connected with the automobile single-chip microcomputer for processing through the rotation speed sensor cooperating with the vortex fan. The cross-sectional area of the metering pipe is known to calculate the refueling amount. The vehicle owner can know the refueling amount. The fixed pipe is fixedly connected with a fixing assembly inside the pipe for stabilizing the oil gun head, so that the oil gun can be more stable during refueling, and the overall sealing performance is improved.

[0007] Based on different models and brands of automobiles, the design and size of the oil tank filler may vary, which may cause the automobile refueling recorder to be difficult to install or require a special adapter on some automobiles. The accuracy of ultrasonic flow sensors may be affected under different temperature, pressure and flow rate conditions, and needs to be calibrated regularly to ensure the accuracy of the readings. Since the recorder is located at the oil tank filler, it is easily affected by dust, moisture and oil stains, which may shorten the durability and life of the equipment, and requires regular maintenance and cleaning.

[0008] The automobile refueling metering device needs to be fixed in the connection pipe between the refueling hole and the oil tank. The design of the refueling hole and the oil tank may vary for different vehicle models, making the installation of the device complex and not necessarily suitable for all vehicle models. The delay and accuracy of real-time data display may also be a problem.

[0009] The vortex fans of the refueling metering and detection equipment may be affected by oil stains, fouling and other factors during long-term use, causing a decrease in sensitivity and accuracy. The cooperation accuracy of the vortex fan and the rotation speed sensor is relatively high, and once there is wear or failure, the accuracy of the metering result may also be affected. The rubber material may age at high or low temperatures or after long-term use, causing a decrease in sealing performance. The metering structure is relatively complex and may require frequent maintenance and calibration, increasing the use cost. The utility model discloses
