Description

Technical Field

[0001] The utility model relates to the technical field of impact detection equipment, in particular to an impact detection device. Background Art

[0002] A common impact force detection device is the impact sensor, a device used to measure the force and duration of an impact on an object. It typically consists of a sensitive element and a signal processing unit. The sensitive element, which can be a piezoelectric element, strain gauge, or accelerometer, converts the impact into a corresponding electrical signal. The signal processing unit receives the electrical signal generated by the sensitive element and amplifies, filters, and converts it, ultimately outputting the impact force and duration as a digital or analog signal. Impact sensors are commonly used in automotive crash testing, sports equipment testing, product packaging testing, and other fields to evaluate the performance and safety of objects subjected to impact.

[0003] When performing existing impact tests, most of them can only generate impact force on the object being impacted in a certain direction, and it is difficult to impact multiple locations on the surface of the impacted object. Therefore, a new technical solution is needed to solve this problem. Utility Model Content

[0009] In order to enable the connecting column to rotate stably inside the chamber, as a preferred impact detection device of the present invention, a ring is fixed to the outside of the connecting column by bolts, and the ring contacts the bottom of the first mounting plate and the second mounting plate.

[0010] In order to reduce the resistance encountered by the connecting column when it moves inside the chamber, as a preferred impact detection device of the present invention, the connecting column is covered with a sleeve on the outside, and the sleeve is in rolling contact with the inner wall of the chamber.
