[0002] With the rapid promotion of electronic technology in automobiles, intelligent control of various parts of automobiles has been realized. The oil level sensor is used to detect the amount of fuel, and the detected signal is displayed on the car dashboard. Nowadays, the oil level sensor has become one of the indispensable sensors for automobiles. The sensing part of the oil level sensor is a coaxial container. When the oil enters the container, it causes a change in the capacitance between the sensor housing and the sensing electrode. The accuracy of the oil level sensor has a great impact on the driver, and may even cause the car to break down. Therefore, in the production of the oil level sensor, it is necessary to calibrate the oil level sensor product. At present, the calibration of the oil level sensor is usually carried out by immersing the handheld sensor in an oil barrel for detection. The detection result is affected by human operation and has low accuracy. In addition, only one oil level sensor can be detected at a time, and the detection efficiency is low.

[0003] Traditional oil level detection devices may be prone to oil leakage due to imperfect sealing design after long-term use or in harsh environments. This not only causes waste of resources, but may also cause environmental pollution and safety hazards. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-3 , the utility model provides the following technical solutions:

[0027] An oil level detection tool for an oil level sensor, comprising:

[0028] Oil pipe 1;

[0029] A connecting frame 2, the connecting frame 2 is arranged at the upper end of the oil pipe 1, the upper end of the oil pipe 1 is fixedly connected with a first flange 3, the lower end of the connecting frame 2 is fixedly connected with a second flange 4, and the second flange 4 and the first flange 3 are threadedly connected by bolts;

[0030] A detection device 5, the detection device 5 is fixedly connected to the upper end of the connecting frame 2, and a detection tube 6 is fixedly connected to the lower end of the detection device 5, and the detection tube 6 matches the oil pipe 1;

[0031] The first connecting pipe 7 is fixedly connected to the circumferential surface of the oil pipe 1 , and the side end of the first connecting pipe 7 is fixedly connected to the oil level box 8 .

[0032] In a specific embodiment of the utility model, the oil pipe 1 is made of corrosion-resistant material to ensure that no chemical reaction or corrosion occurs when it is in long-term contact with various oil products, thereby improving the service life of the tooling and the measurement accuracy. The inner wall of the oil pipe may also be specially treated, such as polishing, to reduce oil residue and ensure that the starting conditions of each test are consistent. The connecting frame 2 is designed as an adjustable structure, which can adapt to oil pipes 1 of different diameters, thereby improving the versatility of the tooling. The connecting frame is light and has high strength, which is convenient for installation and operation while ensuring the stability of the overall structure. The design of the first flange 3 and the second flange 4 takes into account the sealing and easy assembly. The flange surface is processed with high precision to ensure a close fit with the corresponding components and reduce the risk of oil leakage. The flanges are fastened by high-performance bolts 12 and sealing rings 11, which not only ensures the firmness of the connection, but also ensures the sealing effect of the oil circuit. The detection device 5 integrates high-precision sensor technology, which can monitor and transmit oil level data in real time. Some designs may also include a temperature compensation function to correct the measurement error caused by oil temperature changes. The interior of the detection tube 6 is clean and unobstructed, ensuring that the sensor signal is transmitted without interference, and its length is designed to match the oil pipe 1, so that it can penetrate deep into the fuel tank to accurately measure the oil level. As an auxiliary structural member, the first connecting pipe 7 is not only used to enhance the structural stability of the oil pipe 1, but also may serve as an installation interface for other accessories. The scale lines 13 on the side end of the oil level box 8 provide convenience for intuitive observation, while the setting of the tempered glass cover 14 protects the internal structure from external environmental influences, such as dust, water vapor, etc., and also facilitates the observation of oil level changes. In summary, the oil level detection tooling of the oil sensor realizes efficient and accurate monitoring of the oil level through the coordinated work of carefully designed components. It is suitable for a variety of industrial and vehicle maintenance scenarios, and improves the automation and intelligence level of oil level management.

[0033] For details, please refer to Figure 1-3 A scale line 13 is provided at the side end of the oil level box 8, and a tempered glass cover 14 is provided at the side end of the oil level box 8.

[0034] In this embodiment: the detailed design of the oil level box 8 pays special attention to practicality and convenience of observation. The side end of the oil level box 8 is not only provided with clearly visible scale lines 13, but these scale lines are also helpful for quickly judging the oil level on site, and even in the absence of electronic display equipment, basic oil volume estimation can be performed, providing an intuitive visual reference for operators. The distribution of the scale lines is scientific and reasonable, ensuring that each small section of oil level change within the measurement range can be accurately marked. In addition, in order to protect the internal structure and maintain good visual transparency, a durable tempered glass cover 14 is also added to the side end of the oil level box 8. The tempered glass cover can not only effectively prevent external impact from damaging internal precision components, such as scale lines or potential electronic display screens, but also its high transparency ensures that even under the protection of the tempered glass cover, the observer can still clearly read the scale line indication or check the oil level, and the clarity of observation will not be sacrificed due to the additional protective layer. Such a design not only enhances the overall durability of the tooling, but also optimizes the user experience and ensures the safety and efficiency of the detection process.

[0035] For details, please refer to Figure 1-3 A second connecting pipe 9 is fixedly connected to the circumferential surface of the oil pipe 1 , and a third flange 10 is fixedly connected to the side end of the second connecting pipe 9 .

[0036] In this embodiment: the structure of the oil pipe 1 has been further expanded and strengthened, which is specifically reflected in that a second connecting pipe 9 is fixedly connected to the circumferential surface of the oil pipe. This design not only adds an additional interface or channel to the oil pipe system, which is convenient for connecting other auxiliary equipment or multi-functional expansion, such as installing a cleaning device, a pressure test interface, etc., but also enhances the modularity and flexibility of the entire system through such a layout. The side end of the second connecting pipe 9 is specially fixedly connected to the third flange 10. The introduction of this flange element is intended to provide a standardized connection interface. The third flange 10 can be adapted to accessories or pipelines of various specifications, so that the oil level detection tooling of the oil level sensor can be more easily integrated into different working systems. Whether it is direct oil circuit expansion, access to the monitoring system or regular maintenance inspection, the third flange can be used to achieve fast and reliable connection, which greatly improves the versatility and scope of application of the tooling.

[0037] For details, please refer to Figure 1-3 A sealing ring 11 is arranged between the first flange 3 and the second flange 4 .

[0038] In this embodiment, the sealing measure between the first flange 3 and the second flange 4 is particularly emphasized, that is, a sealing ring 11 is provided. This design is crucial because it is directly related to the sealing and reliability of the oil circuit system. As an elastic element, the sealing ring 11 is usually made of oil-resistant, high-temperature-resistant, and wear-resistant rubber or synthetic materials. Its function is that when the first flange 3 and the second flange 4 are connected by bolts, although it is not directly mentioned, it should be understood from the context that the sealing ring will be compressed to form a tight sealing interface to prevent oil from leaking from the gap between the two flanges. The application of the sealing ring 11 in this embodiment not only ensures the closure of the oil circuit during the oil level detection process of the oil level sensor, avoids environmental pollution and safety hazards, but also protects the detection equipment from oil erosion and extends the service life of the entire system. The selection and installation of the sealing ring must accurately match the flange size to ensure that a good sealing effect can be maintained when subjected to working pressure and temperature changes. This is one of the basic guarantees for achieving stable and efficient operation of the oil level detection tooling.

[0039] For details, please refer to Figure 1-3 , the diameters of the first flange 3 and the second flange 4 are equal.

[0040] In this embodiment: the diameters of the first flange 3 and the second flange 4 are designed to be equal, which is a detail of great engineering significance. Equal diameters mean that the two flanges can be directly aligned and fastened with the same bolt specifications, which simplifies the installation process, reduces the possibility of mismatching, and improves assembly efficiency and connection reliability. The design of equal diameters also facilitates standardized production and inventory management, and accessories such as sealing rings 11 and bolts of the same specifications can be used universally, reducing manufacturing costs and maintenance complexity. In practical applications, this helps users quickly replace or adjust flange components, especially when regular maintenance or emergency repairs are required, and can quickly restore the normal operation of the oil level detection tooling of the oil sensor.

[0041] For details, please refer to Figure 1-3 , the length of the detection tube 6 is equal to the length of the oil pipe 1.

[0042] In this embodiment: the length of the detection tube 6 is designed to be exactly equal to the length of the oil pipe 1. This design decision is based on several key considerations. First, the equal length design ensures that the detection tube can be completely embedded in the oil pipe, thereby achieving the best detection coverage. This means that no matter where the oil level is in the oil tank, the detection device 5 can accurately sense and record the oil level information, thereby improving the comprehensiveness and accuracy of the measurement. Secondly, the equal length makes the entire detection system more unified and harmonious in structure, which is conducive to maintaining the balance and stability of the system, especially when there is oil fluctuation inside the oil tank or vibration outside. It can effectively reduce the shaking or offset problems that may be caused by length mismatch, thereby improving the stability of the measurement.

[0043] Working principle and use process of the utility model: Confirm that all parts of the oil level detection tooling of the oil level sensor are intact, especially the sealing ring 11, the tempered glass cover 14 and the flanges 3, 4 and 10 are damaged or loose. Check whether the detection device 5 is properly connected to the power supply if necessary, and ensure that all electronic components function normally. Install the tooling: Fix the first flange 3 to the upper end of the oil pipe 1 through a threaded connection to ensure that the connection is well sealed. Fix the second flange 4 to the lower end of the connecting frame 2 by bolts and align it with the first flange 3. After installing the sealing ring 11, tighten it with bolts to ensure that there is no leakage between the flanges. Connect the detection tube 6 to the connecting frame 2 through the detection device 5, and ensure that the detection tube extends into the interior of the oil pipe 1 to meet the detection depth requirements. Install the second connecting pipe 9 and the third flange 10, and connect other auxiliary equipment or perform specific function expansion as needed. Calibration and testing: After the first use or replacement of important components, perform system calibration to ensure the accuracy of the test results. This may include zero point calibration and range calibration of the electronic detection device. Perform a no-load test to confirm that the scale line 13 in the oil level box 8 is consistent with the value displayed by the detection device, or verify that it is correct through an electronic display. Actual test: slowly insert the assembled detection tool into the oil tank to be tested until the bottom of the oil pipe 1 touches the oil surface, and be careful to avoid violent collisions. Observe the rise of the oil level in the oil level box 8, read the oil level directly through the scale line 13, or check the digital oil level reading through the display screen of the detection device 5.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
