When the tablet is folded, pull the driving dial 406 to disengage the driving gear 406 from the driven gear 403, and align the sheave 401 with the driving dial 405. The sheave 401 rotates with the rotation of the driving dial 4051, and then Driven by the driven shaft 402 to rotate the right plate, the driving dial 405 rotates once, folds 90°, rotates twice, and the plates are folded and overlapped;

When the sunshade assembly is folded, the driving gear 406 is meshed with the driven gear 403. With the rotation of the driving dial 4051, the driving shaft 407 drives the shaft sleeve 404 of the driven gear 403 to rotate through the gear transmission, and the shaft sleeve 404 passes through the L-shaped connecting rod. Drive the corresponding sunshade frame to rotate, so as to realize the folding of the sunshade.

The device realizes two functions with the same active dial 405 member, has a simple and compact structure, and has high application value. The opening principles of the above-mentioned components are similar and will not be repeated here.

It should be noted that the above-mentioned electronic control devices are equipped with a power supply and are waterproofed.
