Detailed Description

The structural and operational principles of the present invention are described in detail below with reference to the accompanying drawings:

in the following description, the terms "first," "second," and "third" are used merely to distinguish one element, component, region, or section from another element, component, region, layer, or section, and do not necessarily indicate a sequential order. Furthermore, relative terms such as "lower" and "upper" may be used herein to describe one element's relationship to another element, it being understood that the relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one figure is turned over, elements described as being on the "lower" side of other elements would then be oriented on the "upper" side of the other elements. This represents only a relative, not an absolute, positional relationship.

Fig. 1A and 1B are schematic side views of an embodiment of an electronic device. As shown in fig. 1A and 1B, the electronic device 1 includes a lower housing 10, a keyboard module 20, an upper housing 30, and a second magnet assembly 40. The lower housing 10 includes a keyboard arrangement area 10A. The keyboard module 20 is disposed in the keyboard setting area 10A and includes a first magnet assembly 15. The keyboard arrangement area 10A may be a recess of the lower casing 10 to receive the keyboard module 20. The upper casing 30 is connected to the lower casing 10 through a rotation shaft seat 35. The upper housing 30 defines a magnetic setting area 30A, and the magnetic setting area 30A corresponds to the keyboard setting area 10A. The second magnet assembly 40 is disposed in the magnetic disposition area 30A, and the magnetic pole direction of the second magnet assembly 40 is opposite to that of the first magnet assembly 15, so that the first magnet assembly 15 is magnetically repulsive when approaching the second magnet assembly 40.

In more detail, the term "magnetic pole direction" as used herein refers to a direction from the south pole (S) to the north pole (N) of the magnetic element or a direction from the north pole (N) to the south pole (S). The magnetic pole direction of the second magnet assembly 40 is opposite to that of the first magnet assembly 15 such that when the lower and

upper housings

10 and 30 are closed, the second magnet assembly 40 and the south (S) or north (N) poles of the first magnet assembly 15 face each other, and the second magnet assembly 40 and the first magnet assembly 15 are vertically projected, at least a portion of which overlap each other.

The electronic device 1 further includes a display screen 50, wherein the display screen 50 is disposed in the upper housing 30, and a vertical projection of the second magnet assembly 40 overlaps at least a portion of the display screen 50. In more detail, when the magnetic pole direction of the second magnet assembly 40 and the south pole (S) or the north pole (N) of the first magnet assembly 15 face each other, the keyboard module 20 is pushed down by repulsive force. In this way, the display screen 50 is prevented from contacting the keyboard module 20, so that the gap between the upper casing 10 and the lower casing 30 can be reduced in design, and the electronic device 1 can be thinned.

Fig. 2 is a schematic cross-sectional view of a first embodiment of a keyboard module. As shown in fig. 2, the keyboard module 20 includes a plurality of key caps 21, the first magnet assembly 15 includes a plurality of first magnet blocks 17, and the first magnet blocks 17 are respectively installed in the key caps 21.

Fig. 3 is a schematic cross-sectional view of a first embodiment of a keyboard module. Referring to fig. 3 together with fig. 2, the first magnet assembly 15 of the second embodiment includes a plurality of magnet powders 19, and the magnet powders 19 may be formed by mixing the plastic slurry for forming the key cap 21 with the magnet powders 19, and then magnetizing the molded plastic slurry with a specific magnetic field to make the key cap 21 have a specific magnetic pole direction. Thus, since the key cap 21 has a specific magnetic property, no additional magnet is required, and the weight is further reduced.

Figure 4 is a schematic cross-sectional view of a first embodiment of a second magnet assembly. As shown in fig. 4, the second magnet assembly 40 is a magnet sheet, more specifically, a magnet sheet covering the magnetic arrangement region 30A entirely, and when the lower housing 10 and the upper housing 30 are closed, the vertical projection of the second magnet assembly 40 substantially coincides with the vertical projection of the keyboard module 20.

Figure 5 is a schematic cross-sectional view of a second embodiment of a second magnet assembly. As shown in fig. 5, the second magnet assembly 40 includes a bottom plate 41 and a plurality of second magnet pieces 43, and the second magnet pieces 43 are disposed on the bottom plate 41 and respectively correspond to the keycaps 21. Here, "corresponds to" means that the vertical projection of the second magnet piece 43 substantially coincides with at least a part of the vertical projection of the key cap 21 when the lower casing 10 and the upper casing 30 are closed. In this way, the key cap 21 can be pushed to sink by the repulsive force between the second magnet pieces 43 and the first magnet pieces 17. Here, by precise alignment, the effect of pushing the key cap 21 to sink can be achieved by using a smaller magnetic force.

The above embodiments of the second magnet assembly 40 of fig. 4 and 5 can be used in combination with the embodiment of the keyboard module 20 shown in fig. 2 and 3.

Fig. 6 is a schematic cross-sectional view of a third embodiment of a keyboard module. As shown in fig. 6, the keyboard setting area 10A is further provided with an elastic member 60, the keyboard module 20 is mounted on the elastic member 60, and the first magnet assembly 15 is a first magnet sheet and is mounted at the bottom of the keyboard module 20. Unlike the first and second embodiments, the repulsive force pushes the entire keyboard module 20 to sink, not the individual key caps 21. To achieve this, the second magnet assembly 40 is generally the manner of fig. 4. When the upper housing 30 is opened and separated from the lower housing 10, the entire keyboard module 20 can be reset by the elastic member 60 due to the attenuation of the repulsive force.

In summary, by simply passing the repulsive force between the magnets, when the upper housing 30 and the lower housing 10 are closed, the keyboard module 20 is pushed to move downward, so as to avoid the display screen 50 contacting the keyboard module 20, so that the gap between the upper housing 30 and the lower housing 10 can be reduced in design, the electronic device 1 can be further thinned, and the complex mechanism is simplified.

Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
