For example, the first sliding portion 41 may be two U-shaped grooves formed at two ends of the sealing member 4, and the two U-shaped grooves may be snapped on the second sliding portion 13 for sliding.
In this embodiment, the sealing member 4 is provided with a first sliding portion 41, the groove 12 is provided with a second sliding portion 13, and the first sliding portion 41 is engaged with the second sliding portion 13, so that the sealing member 4 moves relative to the second housing 1, and thus the electromagnetic member 6 has less resistance to driving the sealing member 4 to move relative to the second housing 1.
As a specific implementation manner, taking an electronic device as a mobile phone with a scroll screen as an example, a magnetic field generated by the electromagnetic element 6 attracts or repels the sealing element 4, and the sealing element 4 interacts with the first magnetic element 7 and the third magnetic element 8 to control the sealing preload between the sealing element 4 and the flexible screen 2, which can be used to solve the problem that in the prior art, because the sealing element 4 is arranged between the housing of the mobile phone and the flexible screen 2, the sealing element 4 scrapes the flexible screen 2 during the repeated movement of expansion or contraction of the scroll screen, the service life of the mobile phone is reduced. When the flexible screen 2 and the shell move relatively, namely the reel screen is unfolded or contracted, the electromagnetic part 6 is used for generating a magnetic field to attract the sealing part 4, the second magnetic part 7 and the third magnetic part 8 are not located at the positions corresponding to the grooves 12, the sealing part 4 moves upwards, the sealing prepressing amount is reduced, and the sealing part 4 is prevented from scraping the flexible screen 2; when the reel screen stops unfolding or contracting, the electromagnetic part 6 is used for generating a magnetic field to repel the sealing part 4, the second magnetic part 7 or the third magnetic part 8 is located at the position corresponding to the groove 12, the sealing part 4 moves downwards, the sealing prepressing amount is increased, and the sealing effect is achieved.
