Description

Technical Field

[0001] This utility model belongs to the field of pressure sensor testing technology and relates to a pressure sensor testing system. Background Technology

[0002] In the field of electronic component testing, vibration, shock, and high / low temperature testing are crucial for ensuring the stable and reliable operation of electronic components in complex environments. As an important component of electronic components, the accurate evaluation of pressure sensors is of paramount importance to many industries, such as aerospace, automotive manufacturing, and industrial automation.

[0003] With the continuous advancement of technology and the increasing complexity of application scenarios, the performance requirements for pressure sensors are becoming increasingly stringent. To comprehensively and accurately detect the performance of pressure sensors under various extreme conditions, a complete and efficient testing system needs to be constructed. However, in actual testing processes, existing testing methods and systems face numerous challenges.

[0004] First, the diversity of test benches presents a significant challenge to the compatibility of pressure sensor testing systems. In practical applications, pressure sensors need to be tested on various types and specifications of test benches, including vibration benches, impact benches, and high- and low-temperature environment test benches. Different test benches have their own unique structures, dimensions, and installation requirements. This necessitates that pressure sensor testing systems possess good versatility and adaptability, enabling them to be installed reasonably and stably on these benches and to achieve precise matching with various testing equipment. However, current market testing systems often lack this broad adaptability, typically only capable of testing on one or a few specific test benches. Furthermore, traditional pressure sensor testing systems usually only allow for a small number of samples to be loaded for testing at a time, resulting in lengthy testing processes that cannot meet the demands of large-scale production and mass testing.

[0033] See Figure 1 This utility model discloses a pressure sensor testing system, including a test platform 3 for mounting a pressure sensor 1; the test platform 3 is mounted on a test bench 7 via a bench connecting plate 9; the test platform 3 is provided with an air inlet 2 and an air outlet 5, and the pressure sensor 1 is mounted on the air outlet 5; the pressure sensor 1 is electrically connected to an oscilloscope 6. The test platform 3 is mounted on the test bench 7 via the bench connecting plate 9, a design that allows the test platform 3 to be easily connected and adapted to various test benches. Whether it is a vibration test bench, an impact test bench, or a high-temperature or low-temperature environment test bench, the test platform 3 can be stably installed by adjusting the connection method between the bench connecting plate 9 and the test bench 7, greatly improving the versatility and adaptability of the testing system and reducing the system modification and debugging costs caused by replacing the test bench 7.

[0034] In one feasible embodiment of this utility model, see [link to relevant documentation]. Figure 2 and Figure 3 The test platform 3 has a hexahedral structure, including a first face 31, a second face 32, a third face 33, a fourth face 34, a fifth face 35, and a sixth face 36.

The fourth face 34 and the fifth face 35 are arranged opposite each other; the second face 32 and the third face 33 are arranged opposite each other; the first face 31 and the sixth face 36 are arranged opposite each other. Each face of the test platform 3 is provided with a set of air vents 5. In this embodiment, each face of the test platform 3 is provided with air vents 5, which can simultaneously install multiple pressure sensors 1 for testing. This design, which can install multiple samples for testing at one time, greatly improves testing efficiency, meets the needs of large-scale production and mass testing, and shortens the product research and development and production cycle.

[0035] In one feasible embodiment of this utility model, see [link to relevant documentation]. Figure 5 The test platform 3 has two sets of air inlets 2 on its first surface 31, which are connected to the air outlets 5 on the second surface 32 and the fourth surface 34, respectively. The test platform 3 also has one set of air inlets 2 on its third surface 33, which are connected to the air outlets 5 on its fifth surface 35. The test platform 3 has two sets of air inlets 2 on its fifth surface 35, which are connected to the air outlets 5 on the first surface 31 and the sixth surface 36, respectively.

In this embodiment, several pressure sensors 1 to be tested can be mounted simultaneously on one plane of the test platform 3, and even more can be mounted on all six surfaces simultaneously; this improves testing efficiency and shortens testing time.

The plurality of second bolt holes 8 are evenly spaced on the test bench 7.
