AI Technical Summary
Technical Problem
In electronic product testing, when there are many buttons concentrated in a small area, existing technologies cannot effectively protect the buttons, which makes the pressing mechanism prone to damaging the buttons and is also costly.
Method used
The design employs a combination of guide components, floating plates, shock-absorbing components, and pressing components. Through the cooperation of the floating plate, guide rod, and compression spring, the buttons are buffered and protected, reducing the number of parts used and simplifying the button pressing mechanism.
Benefits of technology
Effectively avoids button damage, reduces shock absorption and protection costs, and ensures smooth button testing.

Abstract
The utility model discloses a key pressing mechanism for testing an electronic product. The key pressing mechanism comprises a bottom plate, a guide assembly, a floating plate, a damping assembly and a pressing assembly, the bottom plate is erected above a product to be tested; the guide assembly comprises a plurality of guide rods which penetrate through the bottom plate and are fixedly connected with the bottom plate, the guide rods at least form sliding mounting parts above the bottom plate, and limiting pieces are fixed to the top ends of the guide rods; the floating plate is located above the bottom plate and slidably connected to the sliding installation parts of the guide rods in a sleeving mode. The damping assembly comprises a plurality of compression springs which sleeve the sliding mounting parts of the guide rods in a one-to-one correspondence mode, the top ends of the compression springs elastically abut against the bottom ends of the limiting pieces, and the bottom ends of the compression springs elastically abut against the upper surface of the floating plate; the pressing assembly comprises a plurality of miniature air cylinders fixed to the upper surface of the floating plate and a plurality of pressing rods which sequentially penetrate through the floating plate and the bottom plate and are fixedly connected with the telescopic ends of the miniature air cylinders in a one-to-one correspondence mode. The utility model further discloses a product key testing device comprising the key pressing mechanism.
