Description

Technical Field

[0001] The utility model relates to the technical field of impact resistance testing devices, in particular to an acceleration sensor impact resistance testing device. Background Art

[0002] An accelerometer is a sensor that can measure acceleration. It is widely used in various fields, including the automotive industry, aerospace industry, industrial production, and healthcare. The working principle of an accelerometer is mainly based on the relationship between mass and force. It is usually composed of a mass block, a damper, an elastic element, a sensitive element, and an adaptive circuit.

[0003] The impact resistance test can evaluate the stability and reliability of the accelerometer when it is subjected to external impact. In a real working environment, the accelerometer may be subjected to various impacts and vibrations, such as car collisions, vibrations of industrial equipment, etc. Through the impact resistance test, these scenarios can be simulated to detect whether the sensor can work normally when subjected to impact and output accurate data.

[0004] Patent document CN219284626U of prior art provides an acceleration sensor impact resistance test device, which adjusts the connecting rod to a suitable position according to the required impact force. When the acceleration sensor needs to be tested, the plug block needs to be directly pulled outward. At this time, the impact hammer will fall downward due to its own gravity and impact the acceleration sensor below. At the same time, when multiple tests are required, it is only necessary to repeat the pre-adjustment steps, so that the impact force of the device is approximately equal when performing tests.

[0005] The above-mentioned prior art, although the impact resistance testing device completes the impact test of the acceleration sensor by directly pulling out the plug block to the outside so that the impact hammer falls downward and impacts the acceleration sensor below, the impact resistance testing device in the patented technology requires the staff to manually control the falling of the impact hammer. When multiple tests are required, the pre-adjustment steps need to be repeated, and the impact hammer needs to be installed multiple times. The operation is cumbersome, and it is impossible to replace the impact hammer of different gravity according to different needs, which reduces the practicality. Therefore, we need an acceleration sensor impact resistance testing device. Utility Model Content
