Description

Technical Field

[0001] This utility model relates to the field of oxygen sensor technology, specifically to an oxygen sensor performance testing device. Background Technology

[0002] The oxygen sensor performance testing device is a specialized instrument used to detect and evaluate the key performance parameters of oxygen sensors. By simulating the operating conditions of oxygen sensors in real-world environments, this device can comprehensively and accurately measure important indicators such as signal response time, sensitivity, linearity, repeatability, and stability. During testing, the device can precisely control the composition, temperature, and flow rate of the test gas, record the sensor's output signal in real time, and process and analyze the measurement data using professional algorithms to generate a detailed test report. This provides reliable data support for the research, development, improvement, and quality control of oxygen sensors. Based on actual usage, the existing oxygen sensor performance testing devices have some shortcomings. For example, they cannot test the compressive strength, which limits the comprehensive evaluation of their mechanical properties and may lead to inaccurate assessment of their durability in practical applications. Moreover, oxygen sensors usually need to operate in high-temperature environments, but existing testing devices cannot simulate such high-temperature environments, thus failing to truly reflect their performance under harsh working conditions and affecting the reliability and practicality of the test results. Therefore, based on actual usage, we have improved the aforementioned existing technologies. Utility Model Content

[0021] Example 1: Please see Figure 1-3 This utility model provides a technical solution: an oxygen sensor performance testing device, including a test platform 1 and a sealing cover 12; A right limiting rod 3 is longitudinally arranged on the top right side of the test bench 1, and a left limiting rod 4 is longitudinally arranged on the top left side of the test bench 1. A fixed seat 5 is arranged at the center of the top right side of the test bench 1, and the fixed seat 5 is located to the left of the right limiting rod 3. An electric telescopic rod 6 is installed on the top of the fixed seat 5. A moving plate 7 is arranged on the left side of the electric telescopic rod 6. Fixed rods 10 are arranged on the front and rear ends of the right middle part of the left limiting rod 4. A clamping plate 11 that cooperates with the moving plate 7 is connected to the right side of the fixed rods 10. The oxygen sensor to be tested is placed on the top of the test bench 1, and its left side is pressed against the right side of the clamping plate 11. At this time, the electric telescopic rod 6 can drive the moving plate 7 to move to the left by telescopic movement, and cooperate with the clamping plate 11 to clamp and fix the oxygen sensor. Then the electric telescopic rod 6 continues to work and applies pressure to the oxygen sensor through the moving plate 7 to achieve the test of compressive strength. The test bench 1 has a top cover and a sealing cover 12. The top left and right sides of the sealing cover 12 are provided with handles 13. The center of the top left and right sides of the inner cavity of the sealing cover 12 is provided with connecting rods 16. The bottom of the connecting rods 16 is provided with fixing plates 17. The bottom of the fixing plates 17 is provided with electric heating plates 18. After the sealing cover 12 is placed on the top of the test bench 1, the electric heating plates 18 heat up from the top sides of the inner cavity of the sealing cover 12, so that the top of the test bench 1 and the sealing cover 12 reach a high temperature. This allows the oxygen sensor to be tested in a high-temperature environment.

When the movable plate 7 moves left and right by extending and retracting the electric telescopic rod 6, the cooperation between the guide rings 9 and the guide rods 8 can increase the stability of its left and right movement and avoid loosening and shaking.

[0023] Preferably, an observation window 14 is provided at the center of both the front and rear ends of the sealing cover 12. The observation window 14 allows the staff to observe the testing process during the test. A thermometer 15 is provided at the center of the right side of the sealing cover 12.

[0024] Preferably, a counterweight 19 is provided at the center of both the left and right sides of the inner cavity of the sealing cover 12, and a sealing plate 20 is provided around the bottom of the inner cavity of the sealing cover 12. The weight of the counterweight 19 can make the sealing cover 12 stably placed on the top of the test platform 1, and can apply pressure to make the bottom of the sealing plate 20 tightly fit against the top of the test platform 1.

[0025] Preferably, the bottom of the sealing plate 20 and the bottom of the sealing cover 12 are set on the same horizontal plane, and the bottom of the sealing plate 20 is provided with a flexible rubber layer. This arrangement can increase the sealing effect and reduce the influence of the external environment.

A groove is provided in the middle of the left side of the moving plate 7, and a pressure sensor is provided in the center of the right side of the groove cavity. The pressure sensor can be used to know the pressure applied in real time, so as to make accurate test records.

This arrangement makes the entire device more stable when placed and prevents it from moving.

[0027] It should be noted that the electrical components of this utility model have already combed the wire harness during operation, so there will be no problem of wire harness tangling.

[0028] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
