Description

Technical Field

[0001] This utility model relates to the field of mileage testing technology, and in particular to a mileage testing device. Background Technology

[0002] Mileage wheels are widely used in pipeline inspection, robot navigation, and vehicle operation to record mileage. The specific component that detects and records this mileage is the mileage wheel's probe. However, mileage wheels are prone to inaccurate mileage readings after prolonged use. Traditional technologies either lack products that calibrate the mileage wheel probe before use, or while such products exist, the calibration process is often complex. Utility Model Content

[0003] Therefore, it is necessary to provide a mileage testing device to address the problem that traditional technologies do not have products that calibrate the mileage wheel probe before use, or that although there are products that can calibrate the mileage wheel probe, the calibration of the mileage wheel is quite complicated.

[0004] A mileage testing device includes: a support assembly having mounting holes; a power source assembly disposed on the support assembly and located at the mounting holes, a portion of the power source assembly being rotatable relative to the support assembly; a magnetic assembly disposed on the power source assembly; a probe assembly disposed on the support assembly, located at an end of the support assembly and adjacent to the magnetic assembly, the probe assembly being used to sense the magnetic assembly; and a counter assembly disposed on the support assembly, located on the side of the power source assembly, the counter assembly being used to detect the number of rotations of the power source assembly.

[0005] This application discloses a mileage testing device that simulates the continuous rotation of a mileage wheel by rotating a power source component relative to a support component. By detaching the probe component under test from the mileage wheel and directly installing it at the corresponding position on this product, the working state of the probe component on a real mileage wheel can be simulated, allowing for specialized testing and calibration of its performance. Specifically, one or more magnetic components are installed inside the rotating block of the power source component. During one revolution of the power source component, it generates pulse signals equal to the number of magnetic components. The test mileage value is calculated using the formula: actual mileage = total number of pulses × (circumference of the rotating block of the power source component / number of pulses per revolution). A counter component senses the magnetic components and records the number of revolutions of the power source component, calculating a standard mileage value. By comparing the test mileage value with the known standard mileage value of the power source component, the accuracy and consistency of the probe component's response can be objectively and quantitatively evaluated, determining whether calibration or replacement is necessary. If they match, the calibration of the probe component ends; otherwise, calibration continues until they match. This design allows for the calibration of the mileage wheel's mileage testing function before use, ensuring accurate mileage recording. Furthermore, the counter component can automatically provide standard mileage values, simplifying the calibration process and significantly reducing the difficulty and time cost of calibration. This makes regular and frequent accuracy checks possible, ensuring the long-term reliability of the mileage measurement system from the source. The mileage testing device disclosed in this application provides an independent, efficient, and accurate testing and calibration platform for the probe assembly removed from the mileage wheel.

[0006] In one embodiment, there are multiple power source components, all of which are mounted on the support component and arranged sequentially along the length of the support component. The number of probe components is the same as the number of power source components, and each probe component is located at one end of the power source component. The number of counter components is the same as the number of power source components, and each counter component is located on one side of the power source component. By setting multiple power source components, probe components, and counter components and arranging them sequentially along the length of the support component, this product can simultaneously test multiple probe components. Specifically, this product can complete batch testing and data acquisition of multiple probe performance within the same time period, avoiding the cumbersome process of testing probes one by one in a sequential manner as in traditional methods. This is particularly suitable for scenarios requiring periodic batch calibration or final inspection on the production line, thereby significantly reducing the total testing time and improving product utilization and overall calibration efficiency.

[0007] In one embodiment, the support assembly includes a support base, a first support block, and a second support block. The support base has the mounting hole. Both the first and second support blocks are disposed on the support base. The first support block is located at the end of the power source assembly, and the probe assembly is disposed on the first support block. The second support block is located at the side of the power source assembly, and the counter assembly is disposed on the second support block. The support base, the first support block, and the second support block provide stable mounting foundations for the power source assembly, the probe assembly, and the counter assembly, respectively. This design ensures that each core functional component can be independently, firmly supported, and accurately installed, effectively improving the measurement stability of the entire testing device during operation and laying the foundation for obtaining accurate test results.

[0008] In one embodiment, a connector is further included, which passes through the first support block and engages with the probe assembly after passing through the first support block. By having the connector pass through the first support block and engage with the probe assembly, the installation stability of the probe assembly during testing is ensured, thereby guaranteeing the accuracy of the test results.

[0009] In one embodiment, the second support block is provided with a mating hole, and the counter assembly is disposed on the second support block and located at the mating hole. By positioning the counter assembly at the mating hole, stable installation of the counter assembly is ensured, thereby guaranteeing the stability of the testing process, enabling the stable acquisition of the standard mileage value of the power source assembly, and ensuring the accuracy of the final calibration result.

[0010] In one embodiment, the first support block includes a first support portion and a first mounting portion. The first support portion is disposed on the support assembly, and the first mounting portion is disposed on the first support portion. The probe assembly is disposed on the first mounting portion. The second support block includes a second support portion and a second mounting portion. The second support portion is disposed on the support assembly, and the second mounting portion is disposed on the second support portion. The counter assembly is disposed on the second mounting portion. The arrangement of the first and second support portions allows the first and second support blocks to stably cooperate with the support assembly. The arrangement of the first and second mounting portions provides the probe assembly and the counter assembly with their respective independent and stable mounting references, thereby ensuring the stability of the overall test. This design provides a guarantee for the accurate testing and calibration of the probe assembly.

[0011] In one embodiment, the support base includes a first support plate and a second support plate. Both the first and second support blocks are disposed on the first support plate and located on the same side of the first support plate. The second support plate is disposed on the first support plate and has the mounting holes. The mounting holes on the second support plate provide stable mounting for the power source components and a stable and reliable core rotation reference for the entire mileage testing device, ensuring the accuracy of the test from a mechanical perspective.

[0012] In one embodiment, the power source assembly has a receiving groove, and the magnetic component is disposed on the power source assembly and located within the receiving groove. By positioning the magnetic component within the receiving groove, the groove provides a pre-defined, size-matched mounting space for the magnetic component. This design ensures that the magnetic component can be precisely fixed in a predetermined position on the power source assembly, thereby guaranteeing the accuracy of its relative sensing relationship with the probe assembly during rotation.

[0013] In one embodiment, the power source assembly includes a drive motor, a drive shaft, and a rotating block. The drive motor is mounted on the support assembly and located at the mounting hole. The drive shaft is mounted on the drive motor. The rotating block is drively connected to the drive shaft. The drive shaft and the rotating block can rotate together relative to the support assembly under the control of the drive motor. The rotating block is provided with the receiving groove. The drive motor, as the power source, is securely mounted on the support assembly, providing standardized rotational motion. The drive shaft, as the output end of the motor, transmits power to the rotating block. The rotating block serves as a functional carrier, and its receiving groove is used for precise mounting of the magnetic component. This design ensures that the rotating block can rotate relative to the support assembly at a stable and repeatable speed under the precise control of the drive motor, thereby highly replicating the working state of the probe assembly on a real odometer wheel. This controllable and stable rotation simulation provides a foundation for generating accurate and reliable standard odometer test signals and ensures the accuracy of the entire calibration process.

[0014] In one embodiment, the receiving groove is located at the end of the rotating block facing the probe assembly, and the receiving groove is disposed opposite to the probe assembly. By positioning the receiving groove at the end of the rotating block facing the probe assembly and distributing it opposite to the probe assembly, the sensing path between the magnetic component and the probe assembly is optimized, ensuring the strength and reliability of the detection signal.

[0015] In one embodiment, the probe assembly is positioned opposite the magnetic assembly. This relative positioning ensures the probe assembly is within the optimal magnetic induction region, enabling the output of stable and reliable pulse signals, thus laying the foundation for accurate counting and calibration.

[0016] In one embodiment, the magnetic component is a magnet. By using a magnet as the magnetic component, the magnet can generate a constant static magnetic field without an external power supply, enabling the probe assembly to sense stably. Furthermore, the magnet meets the basic requirements of mileage detection and also has the advantages of long lifespan and maintenance-free operation. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein.

By removing the probe assembly 3 from the mileage wheel and directly installing it at the corresponding position on this product, the working state of the probe assembly 3 on a real mileage wheel can be simulated, thereby enabling specialized testing and calibration of its performance. Specifically, one or more magnetic components are installed inside the rotating block 23 of the power source assembly 2. During one revolution of the power source assembly 2, it generates pulse signals equal to the number of magnetic components. The test mileage value is calculated using the formula: actual mileage = total number of pulses × (circumference of the rotating block of the power source assembly / number of pulses per revolution). A counter assembly 4 senses the magnetic components and records the number of revolutions of the power source assembly 2, calculating a standard mileage value. By comparing the test mileage value with the known standard mileage value of the power source assembly 2, the response accuracy and consistency of the probe assembly 3 can be objectively and quantitatively evaluated, determining whether calibration or replacement is necessary.
