Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure generally relates to screen
protection and, particularly, to a screen protecting assembly for
an electronic device with a liquid crystal display screen.
[0003] 2. Description of Related Art
[0004] Liquid crystal display (LCD) screens are widely used in
various electronic devices, such as computer monitors and

exposing the screen 15 of the liquid crystal television 100.
[0025] It should be pointed out that the screen protecting assembly
30 may only include one connecting base 31 with the rotating button
33. In this case, the other connecting base 31 is replaced by a
base defining a blind hole in which one positioning portion 351 is
engaged. Alternatively, the sleeve 39 may define a blind hole
instead of the receiving hole 391, and one positioning portion 351
is engaged in the blind hole of the sleeve 39. In addition, the
first latching device 111 and the second latching device 371 can be
other fixing structures, such as a first hook and a second hook
engaging with the first hook. The sleeve 39 can be integrally
formed with the display body 10, and a sound device may be
positioned in the sleeve 39. Thus, the electronic device 100 can
emit sound, and have a small size.
[0026] Referring to FIG. 5, a second embodiment of a television
electronic device 200 includes a display body 50 and a screen
protecting assembly 70 assembled to an end of the display body 50.

free end 731 of the curtain 73 is pulled to cover the screen 55 of
the display body 50, and the free end 731 is fixed to an end of the
display body 50 away from the connecting base 71. The torsion
springs 74 are then deformed to store elastic energy. When the
electronic device 200 needs to be used, the free end 731 disengages
from the display body 50, so that the curtain 10 automatically
rolls up on the pivot shaft 35, driven by the torsion springs 74,
thereby exposing the screen 55 of the liquid crystal television
200.
[0033] It should be appreciated that the torsion springs 74 may be
replaced by other driving members, such as an electronic motor to
drive the pivot shaft 72.
[0034] It is believed that the present embodiments and their
advantages will be understood from the foregoing description, and
it will be apparent that various changes may be made thereto
without departing from the spirit and scope of the disclosure or
sacrificing all of its material advantages.
