Description

Technical Field

[0001] This application relates to the field of magnetic sensor detection technology, specifically to a gear sensor testing device. Background Technology

[0002] When testing the reliability of gear-type sensor chips, high and low temperature testing is a key step in verifying their reliability and performance stability. Due to the fixed distance detection of sensors, traditional testing equipment is bulky and cannot be placed in a standard high and low temperature chamber. The high temperature resistance of the testing equipment is insufficient and cannot withstand long-term high and low temperature cycle testing. There are many types of sensors and a large number of each type need to be tested. Traditional testing equipment can only support single sensor testing. When verifying the temperature drift characteristics of multiple sensors at the same time, the test cycle is long and the test efficiency is low. Utility Model Content

[0004] A gear sensor testing device includes a mirror platform, on which:

[0005] The test structure includes a test gear and a sensor fixing platform. The sensor fixing platform is located on the outside of the test gear and includes several sensing structures tangent to the test gear. The inner side of the sensing structure is a sensing surface, and the outer side is a sensor placement structure area. Each sensor placement structure area is equidistant from the center of the gear. The center of the test gear is connected to a motor through an optical axis.

[0006] The horizontal support plate is a bent structure located on the lower side of the optical axis. One end is connected to the mirror platform, and the other end is connected to the lower part of the motor.

[0007] Preferably, on the mirror platform, vertical support plates are provided on both sides of the test gear, and bearings are provided on the vertical support plates. The optical axis passes through the center of the gear and is connected to the output end of the motor through the bearings.

[0008] Preferably, the sensor mounting platform is a prism structure made of stainless steel.

[0009] Preferably, a detection gap is provided between the sensor fixing platform and the test gear.

Simply place the sensor in a fixed position and adjust the gear to the appropriate position to start the test.

[0015] This application allows for the simultaneous testing of more sensors at both high and low temperatures by increasing the number of gears and sensor mounting platforms when the high-temperature detection sensor is in operation. Attached Figure Description

[0020] The present application will be further described below with reference to the accompanying drawings. The structure and principle of the present application are very clear to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

[0021] Based on the format of the specific embodiments in the patent specification, and according to the provided reference numerals, the above text is annotated as follows:

[0022] Figure 1 This is a front view of one embodiment of a gear sensor testing device according to this application. Figure 2 for Figure 1 Left view of the embodiment shown, Figure 3 for Figure 1 Top view of the embodiment shown.

[0023] Combination Figures 1 to 3It is understood that the gear sensor testing device of this application includes a mirror platform 1 and a motor 7. The mirror platform 1 is equipped with a testing structure and a horizontal support plate 5. The testing structure includes a test gear 3 and a sensor fixing platform 2. The sensor fixing platform 2 is located outside the test gear 3 and includes several sensing structures tangent to the test gear 3. The inner side of the sensing structure is the sensing surface, and the outer side is provided with a sensor placement structure area 9. Each sensor placement structure area 9 is equidistant from the center of the gear. The center of the test gear 3 is connected to the motor 7 via an optical axis 6. The horizontal support plate 5 is a bent structure located below the optical axis 6, with one end connected to the mirror platform 1 and the other end connected to the lower part of the motor 7. Here, "inner" refers to the side closer to the gear center, and "outer" refers to the side farther from the gear center.

[0024] The mirror platform 1 provides a stable and planar testing environment, ensuring precise alignment of the sensor and gear, thereby improving testing accuracy. The sensor mounting platform 2 is positioned outside the test gear 3, with each sensor placement area 9 equidistant from the gear center. This layout facilitates uniform and accurate sensor detection of the gear. The horizontal support plate 5 has a bent structure, with one end connected to the mirror platform 1 and the other end connected to the lower part of the motor 7. This structure helps support the motor 7 and maintain its stability. Without the horizontal support plate 5, the optical axis 6 connected to the motor 7 would need to directly contact the test chamber, affecting the test results. The horizontal support plate 5 reduces the impact of vibration on the test results.

[0025] On the mirror platform 1, vertical support plates 4 are provided on both sides of the test gear 3. Bearings 8 are installed on the vertical support plates 4. The optical shaft 6 passes through the center of the gear and is connected to the output end of the motor 7 via the bearings 8. The vertical support plates 4 enhance the structural stability of the device and ensure the smoothness of the test gear 3 during rotation. The support of the bearings 8 reduces friction during the rotation of the optical shaft 6, improves transmission efficiency, and ensures the accuracy and stability of the gear rotation.

[0026] The sensor mounting platform 2 has a prismatic structure and is made of stainless steel. Stainless steel has good corrosion resistance and mechanical strength, ensuring the stability and durability of the sensor mounting platform 2 during long-term use.

[0027] A detection gap is provided between the sensor mounting platform 2 and the test gear 3. The detection gap ensures an appropriate distance between the sensor and the gear, avoiding direct contact between the sensor and the gear while ensuring that the sensor can accurately detect the rotation signal of the gear.

[0028] A coupling 10 is installed on the side of motor 7 near the mirror platform 1, and the output shaft of motor 7 is connected to optical shaft 6 through coupling 10. The use of coupling 10 improves the reliability and transmission efficiency of the connection between motor 7 and optical shaft 6, and reduces energy loss during transmission.

[0029] The gear sensor testing device is housed inside a test chamber, while the motor 7 is located outside the chamber. A horizontal support plate 5 is fixedly connected to the motor 7 through the test chamber's operating hole. Placing the device inside the test chamber allows for the simulation of different testing environments (such as high and low temperatures), improving the device's adaptability and testing range. The motor 7's location outside the test chamber avoids potential environmental influences (such as high temperature, low temperature, and humidity) that might occur inside the chamber, ensuring its normal operation and stability. The horizontal support plate 5, fixedly connected to the motor 7 through the test chamber's operating hole, connects the motor 7 to the internal components of the device while maintaining the test chamber's airtightness.

[0030] Sensors are placed within sensor placement area 9, and these sensors are connected to testing instruments. In use, the mirror platform 1 is placed inside the high and low temperature chamber. The horizontal support plate 5 passes through the operating hole of the high and low temperature test chamber and is fixedly connected to the DC motor 7 outside the chamber. The positions of the sensor fixing platform 2 and the testing gear 3 are adjusted so that they are on the same vertical plane. The sensor is placed in sensor placement area 9 via the sensor fixing platform 2, with the gear 3 tangent to the sensor. The fixing platform connects to the power supply and testing instruments to power the sensor and detect its output status. When the high-temperature sensor is operating, more sensors can be tested simultaneously at high and low temperatures by increasing the number of gears and sensor fixing platforms 2.
