In other embodiments, referring to fig. 4, the second housing 310 is provided with a see-through portion 314 at a side facing away from the first housing 100, at least the see-through portion 314 being capable of passing light, for example, made of transparent plastic, so that a user can view an image through the see-through portion 314. In the illustrated embodiment, the see-through portion 314 is connected to the main structure of the second housing 310 as a separate member, for example to the second back plate 311 and/or the second side plate 312 of the second housing 310. In other embodiments, the perspective portion 314 may be integrally connected with the main structure of the second housing 310, and in this case, the second housing 310 may be integrally transparent. By providing the see-through portion 314, electronic devices such as the electronic ink 320 can be protected without obstructing the user's view of the image.
In some embodiments, the second housing 310 can be detachably connected to the first housing 100 through the connection component of the foregoing embodiments, and meanwhile, the electronic ink screen 320, the NFC module, and the like may also be detachably connected to the second housing 310, for example, the electronic ink screen 320 and the NFC module are integrated into a display module through a third housing, and the display module is detachably connected to the second housing 310, so that, when the electronic ink screen is not needed, the display module may be separated from the second housing 310, and the second housing 310 may be used for placing other objects.
As one way of detachably connecting the display module to the second housing 310, the second housing 310 may specifically include a front housing and a rear housing, where the front housing and the rear housing define the aforementioned mounting cavity 313 therebetween, and the front housing and the rear housing can slide relatively to open the mounting cavity 313 or close the mounting cavity 313, when the mounting cavity 313 is in an open state, the display module may be mounted in the mounting cavity 313, and when the mounting cavity 313 is in a closed state, the display module may be held in the mounting cavity 313. For example, the portion including the second back plate 311 and the second side plate 312 in fig. 4 may be regarded as a front housing, the perspective portion 314 may be regarded as a second housing, the edge of the perspective portion 314 along the length direction is provided with a protrusion, the edge of the second side plate 312 along the length direction is provided with a sliding rail, and the protrusion is located in the sliding rail and can slide along the sliding rail, so that the front housing and the rear housing can slide relatively along the length direction. In use, the display module is first mounted in the mounting cavity 313, and then the front housing is detachably connected to the first housing 100 through the various connecting components, so that the connection between the display device 300 and the first housing 100 can be achieved; when the display device 300 is detached from the first housing 100, the display module is detached from the second housing 310, or the display module is directly detached from the second housing 310 on the basis that the second housing 310 is kept connected with the first housing 100, so that the display module can be detached. That is, the present embodiment provides a more flexible use manner, and a user may separate the entire display device 300 from the first housing 100, or may leave the second housing 310 to place other objects.
In other embodiments, the front housing and the rear housing may be connected by means of a buckle or a threaded fastener, and when the display module needs to be disassembled, the front housing and the rear housing may be separated from each other by means of driving the buckle to deform or unscrewing the threaded fastener.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model. Furthermore, embodiments of the utility model and features of the embodiments may be combined with each other without conflict.
