[0048] A protection plate 430 for protecting the mounting substrate 410 is disposed on the support frame 100 .

[0049] Specifically, the sensor 420 adopts a Hall sensor 420, and the Hall sensor 420 is triggered by the magnetic part 310 at the bottom of the tray 300, so as to detect the voltage change of the Hall sensor 420 to know the distance between the tray 300 and the Hall sensor 420, and according to the encoding of multiple Hall sensors 420, the exact position of the tray 300 can be accurately known, and according to the signal change speed of a single Hall sensor 420 or the signal change of multiple Hall sensors 420, the speed and acceleration of the tray 300 can be calculated.

[0050] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in an optional solution of this embodiment, a guide member 110 is provided on the top of the support frame 100 , and the tray 300 is slidably disposed on the guide member 110 .
