Description

Technical Field

[0001] This invention relates to the field of vehicle fuel level measurement technology, and in particular to a vehicle fuel level measurement device and measurement method. Background Technology

[0002] Vehicle fuel level measurement refers to the real-time or periodic monitoring and recording of the fuel level in a vehicle's fuel tank using specific technologies and equipment. Accurate fuel level measurement not only helps drivers understand the remaining fuel level and prevent unexpected breakdowns due to insufficient fuel, but also plays a significant role in vehicle fuel consumption management and maintenance.

[0003] Common methods and techniques for measuring vehicle fuel level mainly include the following: 1. Mechanical float-type oil meter Principle: The mechanical float-type fuel gauge is a traditional method of measuring fuel level. It typically uses a combination of a float and a mechanical lever to sense the fuel level in the tank. The float moves up and down with changes in fuel level, and the lever transmits the positional changes of the float, driving the pointer to display the fuel level.

[0004] 2. Capacitive fuel level sensor Principle: Capacitive fuel level sensors measure fuel level by detecting changes in capacitance within the fuel tank. As the fuel level changes, the capacitance value changes, and the sensor calculates the fuel level by monitoring these changes.

[0005] 3. Float-type resistance sensor Principle: The float rises or sinks within the tank as the oil level changes. This process is achieved through a combination of the float and a resistor. The float's movement alters the resistance value, which is then detected by an electronic module and converted into oil level information.

[0006] Existing vehicle fuel level measurement devices, which use a float, are prone to contamination by fuel impurities such as oil residue over prolonged use. This residue adheres to the float's surface, causing it to become dirty. Because cleaning the float is difficult, this buildup of dirt increases friction, potentially hindering its movement and preventing accurate fuel level readings. Consequently, measurement accuracy and real-time feedback are compromised.

[0007] In summary, the existing technology lacks a technique for periodically cleaning the float when measuring vehicle oil levels via a float. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of the prior art by providing a vehicle fuel level measuring device and method.

[0010] Preferably, the cleaning seat has a hollow structure, and a cleaning tank is provided inside the cleaning seat. The bottom end of the cleaning tank is connected to one end of the drain valve, and a groove frame is fixedly connected inside the cleaning tank.

[0012] Preferably, the oil quantity measuring mechanism includes a receiving tube, a motor B is fixedly connected to the outer wall of the top end of the receiving tube, the output end of the motor B extends into the receiving tube and is fixedly connected to a threaded rod, an adjusting seat is threadedly connected to the outer wall of the threaded rod, a movable seat is slidably fitted on the adjusting seat, an electric push rod is fixedly connected to the lower surface of the movable seat, and the other end of the electric push rod extends into the oil tank and is fixedly connected to a float.

[0013] Preferably, the float is slidably fitted with a rotating seat on its lower side, the bottom end of the rotating seat is rotatably connected to the inner wall of the cleaning tank, a motor C is fixedly connected to the outer end of the rotating seat, and an arc-shaped rack C is fixedly connected to the upper side of the float.

[0014] Preferably, the transmission mechanism includes a transmission rod, which is rotatably connected to a rotating seat. A transmission wheel is fixedly connected to one end of the transmission rod, and the transmission wheel meshes with an arc-shaped rack C for transmission. A spiral groove is formed on the outer wall of the other end of the transmission rod. A push-pull ring is slidably fitted on the outer wall of the transmission rod, and the push-pull ring is slidably fitted to the rotating seat. A protrusion on the inner wall of the push-pull ring is slidably fitted to the inner wall of the spiral groove. A guide rod is fixedly connected to the bottom end of the push-pull ring, and the outer wall of the bottom end of the guide rod is slidably fitted to the inner wall of the groove frame.

[0015] Preferably, the input end of the liquid extraction seat is connected to the inner wall of the cleaning seat, the output end of the liquid extraction seat is connected to the inner wall of the cleaning tank, a piston is slidably fitted inside the liquid extraction seat, a spring is fixedly connected between the bottom end of the piston and the inner wall of the liquid extraction seat, a contact rod is fixedly connected to the piston, and the contact rod is slidably fitted through the liquid extraction seat and the inner wall of the cleaning seat.

[0016] Preferably, the pressing mechanism includes a pressing rod, which is rotatably connected to the inner wall of the cleaning seat. The outer wall of the pressing rod is slidably in contact with the outer wall of the contact rod. The inner wall of the outer circle of the pressing rod is rotatably connected with a plurality of meshing teeth in an annular structure. A tension spring is fixedly connected between the meshing teeth and the inner wall of the outer circle of the pressing rod. The meshing teeth are engaged with an arc-shaped rack A for transmission.

[0017] A method for measuring vehicle fuel level using a vehicle fuel level measuring device includes the following steps: S1. During vehicle use, the fuel level measurement mechanism can measure the fuel level in the fuel tank in real time. S2. When the oil level measuring mechanism needs to be cleaned, after the oil level measuring mechanism is retracted, rotating the cover will move the oil level measuring mechanism to the cleaning seat side. S3. When the rotating cover rotates, an appropriate amount of cleaning fluid will be injected into the cleaning position of the cleaning seat through the liquid extraction seat. Then, the transmission mechanism will drive the float to wipe and clean the oil level measuring mechanism. S4. After cleaning, the rotating cover will open the drain valve as it rotates, allowing the cleaning wastewater to be discharged.

[0018] Compared with the prior art, the present invention has the following beneficial effects: During the process of measuring the fuel level in a vehicle's fuel tank using a float ball, a float ball wiper is installed. Driven by a transmission mechanism, the rotating float ball wiper reciprocates, cleaning the surface of the float ball and preventing oil stains from adhering to it. The reciprocating motion effectively wipes the surface of the float ball, removing attached dirt and preventing the float ball from becoming obstructed or unbalanced due to oil sludge. This ensures the float ball moves freely within the fuel tank, thereby improving the accuracy and reliability of fuel level measurement and extending the service life of the float ball and related components. By setting up a liquid extraction seat, when the rotating cover drives the oil level measuring mechanism to clean, the pressing mechanism works in conjunction with the liquid extraction seat to automatically draw the cleaning fluid into the cleaning tank, thereby immersing and cleaning the float. The automated cleaning design reduces the need for manual cleaning, and vehicle maintenance personnel do not need to frequently disassemble and clean the float, reducing maintenance costs and workload. By setting a rotating cover, the oil volume measuring mechanism can be easily rotated to the top of the cleaning tank to achieve automatic cleaning. At the same time, by setting an arc-shaped rack B on the rotating cover, the opening and closing of the drain valve can be automatically driven, facilitating the automatic discharge of cleaning waste liquid. This greatly improves the cleaning efficiency and automation level of the oil volume measuring device, maintains the good operation of the system and the cleanliness of the environment, and provides a guarantee for the long-term reliability of the equipment.

[0023] like Figure 5 As shown, the cleaning seat 2 has a hollow structure and a cleaning tank 201 is provided inside the cleaning seat 2. The bottom end of the cleaning tank 201 is connected to one end of the drain valve 9. A grooved frame 202 is fixedly connected inside the cleaning tank 201.

An opening and closing wheel 901 is fixedly connected to the valve stem of the drain valve 9. The opening and closing wheel 901 is engaged with the arc-shaped rack B303 for transmission.

[0025] like Figure 6 As shown, the oil quantity measuring mechanism 4 includes a receiving tube 401. A motor B402 is fixedly connected to the outer wall of the top end of the receiving tube 401.

Under the action of the groove bracket 202, the push-pull ring 604 connected to the guide rod 605 will reciprocate, causing the protrusion in the push-pull ring 604 to slide in the spiral groove 603, thereby driving the transmission rod 601 to rotate in both directions. Then, the transmission rod 601 will drive the connected transmission wheel 602 to rotate, causing the transmission wheel 602 to drive the float ball 5 connected to the arc rack C503 to reciprocate.

[0030] A method for measuring vehicle fuel level using a vehicle fuel level measuring device includes the following steps: S1. During the use of the vehicle, the fuel level in the fuel tank 1 can be measured in real time through the fuel level measuring mechanism 4. S2. When it is necessary to clean the oil level measuring mechanism 4, after the oil level measuring mechanism 4 is retracted, the rotating cover 3 will drive the oil level measuring mechanism 4 to move to the side of the cleaning seat 2. S3. When the rotating cover 3 rotates, an appropriate amount of cleaning fluid will be injected into the cleaning position of the cleaning seat 2 through the liquid extraction seat 7. Then, the transmission mechanism 6 will drive the float 5 to wipe and clean the oil measurement mechanism 4. S4. After cleaning, when the rotating cover 3 is rotated, it will drive the drain valve 9 to open, so that the cleaning wastewater can be discharged.

[0031] Working principle: When it is necessary to clean the float 407, the motor B402 first drives the threaded rod 403 to rotate, so that the threaded rod 403 drives the adjusting seat 404 to move upward, so that the adjusting seat 404 can drive the moving seat 405 to move upward. Then, the electric push rod 406 drives the float 407, so that the float 407 is retracted into the collection tube 401. Then, the motor A301 drives the rotating cover 3 to rotate, so that the rotating cover 3 drives the oil quantity measuring mechanism 4 to rotate above the cleaning tank 201. When the rotating cover 3 rotates, it will drive the connected arc rack B303 to rotate, so that the arc rack B303 drives the opening and closing wheel 901 to rotate, so that the valve stem connected to the opening and closing wheel 901 drives the drain valve 9 to close. Then, when the rotating cover 3 rotates, it will drive the connected arc-shaped rack A302 to rotate, so that the arc-shaped rack A302 meshes with the meshing tooth 802. At this time, it will drive the pressing rod 801 to rotate, so that the pressing rod 801 contacts and squeezes the contact rod 703, so that the contact rod 703 drives the connected piston 701 to move down. In conjunction with the spring 702, the cleaning liquid in the cleaning seat 2 is sucked into the cleaning tank 201. Then, the electric push rod 406 drives the float 407 to be inserted into the cleaning tank 201. Then, the motor C502 drives the connected rotating seat 501 to rotate, so that the rotating seat 501 drives the float 507 to rotate and wipe the outer wall of the float 407. At the same time, under the action of the groove frame 202, the push-pull ring 604 connected to the guide rod 605 will move back and forth, causing the protrusion in the push-pull ring 604 to slide in the spiral groove 603, thereby driving the transmission rod 601 to rotate in both directions. Then the transmission rod 601 will drive the connected transmission wheel 602 to rotate, causing the transmission wheel 602 to drive the float wiping 5 connected to the arc rack C503 to move back and forth, wiping the outer wall of the float 407. After cleaning, the float 407 is retracted into the collection tube 401, and then the rotating cover 3 is reversed. At this time, under the action of the arc rack B303, the opening and closing wheel 901 can be rotated, thereby opening the drain valve 9 to discharge the waste liquid. After the float 407 is drained, it is placed in the oil tank 1. The float 407 floats on the oil surface. As the oil level increases or decreases, the float 407 rises or sinks in the oil tank 1. This process is achieved by combining the float 407 with a resistor. The floating of the float 407 changes the resistance value, which is detected by the electronic module and converted into oil level information.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
