The key assembly provided by the embodiment includes: base plate 10, key cap 70 and elevating assembly 50, the elevating assembly 50 includes: a slide plate 30, a lifting bracket and a drive and lock assembly.
In a specific arrangement, the driving and locking assembly and the lifting bracket are arranged side by side between the key cap 70 and the substrate 10. Therefore, the driving and locking assembly and the lifting bracket share the thickness space, and the thickness of the assembly is favorably reduced.
The lifting support is used for limiting the movement direction and the movement distance of the key cap 70, and the movement distance of the key cap 70 in the vertical direction can be limited in different ways, and in a specific embodiment, the lifting support comprises: the first bracket 51 and the second bracket 52 are hinged, and the first bracket 51 and the second bracket 52 are hinged to form an X shape; one end of the first support 51 is hinged to the substrate 10, the other end of the first support is connected to the key cap 70 in a sliding mode, one end of the second support 52 is connected to the substrate 10 in a sliding mode, the other end of the second support is hinged to the key cap 70, and the hinged end of the first support 51 and the substrate 10 and the hinged end of the second support 52 and the key cap 70 are located on the same side of the hinged point. When the key cap 70 is pressed, the first support 51 and the second support 52 can rotate relative to the key cap 70 and the substrate 10 respectively, the first support 51 and the second support 52 also rotate relative to each other, so that the height of the lifting support is changed, the height of the key cap 70 is changed when the key cap 70 is pressed, and one end of the first support 51 and one end of the second support 52 are hinged with the key cap 70 and the substrate 10 respectively, so that the key cap 70 can be changed in height along a set direction when the key cap 70 is pressed.
The driving and locking assembly in this embodiment includes two parts, which are a first magnetic member 62 and a first magnetic attraction member 61, respectively, and the first magnetic attraction member 61 can be attracted by the first magnetic member 62. The first magnetic member 62 is a magnet, the first magnetic adsorbing member 61 can be made of materials which are common in the prior art and can be adsorbed by the magnet, such as iron, cobalt, nickel, and the like, and the first magnetic adsorbing member 61 can be set into different shapes such as a frame shape as required, that is, the structure shown in fig. 1, at this time, the first magnetic adsorbing member 61 is a bent frame shape, the top end of the frame shape has an opening, and two sides of the opening are connected with the keycap 70 as rotating shafts. When the magnetic slide plate is specifically arranged, the first magnetic part 62 is fixedly connected with the slide plate 30; the first end of the first magnetic adsorption piece 61 is hinged with the keycap 70, and the second end is pressed against the substrate 10 and can slide relative to the substrate 10; when the circuit board 20 is disposed on the substrate 10, the first magnetic attraction member 61 is pressed against the circuit board 20, and it should be noted that when the first magnetic attraction member 61 is disposed between the substrate 10 and the key cap 70, the first magnetic attraction member 61 is disposed in an inclined manner no matter the key cap 70 is in a free state or a pressed state, specifically, as shown in fig. 2 and 3, the first magnetic attraction member 61 is inclined with respect to a vertical direction with a placement direction of the key assembly in fig. 2 and 3 as a reference direction. The first magnetic material 62 is positioned on the side toward which the first magnetic attraction material 61 is inclined when installed. In addition, the magnetic force applied to the end of the first magnetic adsorbing member 61 connected to the key cap 70 provided in this embodiment should be smaller than the magnetic force applied to the end of the first magnetic adsorbing member 61 abutting against the substrate 10, and since the size of the magnetic field generated by the first magnetic member 62 is not changed, when the first magnetic member is specifically disposed, the metal content at the two ends of the first magnetic member 62 should be different, specifically, the metal content at the first end hinged to the key cap 70 is smaller than the metal content at the second end abutting against the substrate 10. In a specific embodiment, the first magnetic attraction member 61 may include a plastic frame 40, but an iron block is disposed at one end of the plastic frame 40 abutting against the substrate 10.
The sliding plate 30 provided in this embodiment can slide relative to the base plate 10, as shown in fig. 1, the middle of the sliding plate 30 has a hollow structure, through which the lifting bracket can pass, and when the lifting bracket moves, the lifting bracket is not limited by the sliding plate 30. In order to ensure the sliding stability of the sliding plate 30, the present embodiment provides a frame 40, and with continued reference to fig. 1, the frame 40 is provided with a through hole for the passing of the lifting bracket; when the lifting support passes through the through hole and is connected with the key cap 70, the frame 40 is fixedly connected with the base plate 10, and the sliding plate 30 is slidably assembled on the frame 40.
In order to facilitate understanding of the lifting assembly 50 provided in the present embodiment, the operation principle of the key assembly will be described in detail with reference to the structures shown in fig. 2 to 4.
Referring first to FIG. 2, FIG. 2 shows a schematic structural view of the key cap 70 in a free state. As can be seen from fig. 2, the first magnetic attraction piece 61 is in an inclined state, and the slide plate 30 slides to a first setting position, which is that the first magnetic attraction piece 62 is located vertically below the hinge point of the first magnetic attraction piece 61 and the keycap 70; the first magnetic part 62 is located on one inclined side of the first magnetic adsorption part 61, and under the adsorption of the first magnetic part 62, the first magnetic adsorption part 61 rotates (rotates counterclockwise), that is, the inclination angle of the first magnetic adsorption part 61 is reduced, and drives the first magnetic adsorption part 61 to rotate to provide a supporting force for the keycap 70, at this time, the first magnetic part 62 is attracted to the second end of the first magnetic adsorption part 61, so that the keycap 70 is lifted; as shown in fig. 3, when the key cap 70 is pressed by an external force, the external force overcomes the magnetic force between the first magnetic absorption member 61 and the first magnetic absorption member 62, the first magnetic absorption member 61 rotates (rotates clockwise), as shown in fig. 3, the distance between the first magnetic absorption member 62 and the first magnetic absorption member 61 increases to Δ, the key cap 70 is pressed, and when the external force disappears, the first magnetic absorption member 62 absorbs the first magnetic absorption member 61, so that the first magnetic absorption member 61 rotates (rotates counterclockwise), and the key cap 70 is pushed to return to the position shown in fig. 2.
When the key cap 70 needs to be locked, as shown in fig. 4, the slide plate 30 is slid, so that the slide plate 30 slides from the first setting position to the second setting position, thereby changing the position of the first magnetic part 62, the first magnetic part 62 drives the first magnetic adsorption part 61 to rotate toward the direction close to the key cap 70, the first magnetic part 62 pushes the first magnetic adsorption part 61 to rotate (rotate clockwise), the included angle between the first magnetic adsorption part 61 and the substrate 10 becomes smaller, at this time, the first magnetic adsorption part 61 drives the key cap 70 to sink, and when the slide plate 30 is locked, the position of the first magnetic part 62 is locked, that is, the key cap 70 is locked.
It should be understood that the clockwise rotation and the counterclockwise rotation described above are determined by the inclination direction of the first magnetic attraction member 61 shown in fig. 2, and when the inclination direction of the first magnetic attraction member 61 is changed, the direction of the rotation is correspondingly changed.
In addition, in the above embodiments, the sliding plate 30 can be implemented by adopting different structures when sliding and locking, taking a notebook computer as an example, the driving member for sliding the sliding plate 30 can be a rotating shaft of the screen, when the screen rotates to the open position, the sliding plate 30 slides to the first set position and locks, when the screen rotates to the closed position, the sliding plate 30 slides to the second set position and locks; or a pulling switch is arranged on the keyboard, when the keyboard is pulled to the first position, the sliding plate 30 slides and locks to the first setting position, and when the keyboard is pulled to the second position, the sliding plate 30 slides and locks to the second setting position.
As can be seen from the above description, in the present embodiment, the driving and locking component is used to control the position of the key cap 70, when the driving and locking component is located at the driving working position, the driving and locking component can provide a lifting force to the key cap 70, so that the key cap 70 can be used normally, and after being pressed down, the key cap returns to the initial position by the lifting force; when the driving and locking assembly is in the locking position, the key cap 70 can be pulled to sink to the position where the key cap 70 is pressed down, and the key cap 70 is locked, at this time, the height of the whole keyboard can be reduced, so that the keyboard is convenient to thin, and the whole mobile terminal is convenient to thin.
It should be understood that the setting position of the magnetic attraction member is not limited to the setting position of fig. 2, but other setting positions may be adopted. As a variation of this embodiment. The driving and locking assembly includes: the fourth magnetic part is fixed on the sliding plate 30, and the third magnetic adsorption part is fixed on one end of the first bracket 51 hinged with the substrate 10, when the fourth magnetic part is specifically arranged, a groove is formed in the first bracket 51, and the third magnetic adsorption part is fixed in the groove; the fourth magnetic member is arranged in the same manner and has the same structure as the first magnetic member 62; the third magnetic adsorption part is the same as the first magnetic adsorption part 61, and the only difference is that the fourth magnetic adsorption part is fixed on the first support 51, and when the slide plate 30 slides to the first set position during specific use, the fourth magnetic part is located on the first side of the first support 51 and adsorbs the third magnetic adsorption part to drive the first support 51 to rotate to provide a supporting force for the keycap 70; when the slide plate 30 slides to the second setting position, the fourth magnetic member is located on the other side of the first bracket 51 and attracts the third magnetic attracting member, locking the key cap 70 at the position when pressed.

By using two oppositely arranged inclined surfaces, the polarities of the opposite inclined surfaces are the same, so that the larger repulsive force can be provided.
As shown in fig. 7, when the key cap 70 is pressed down by a hand, the key cap 70 is pressed down against the repulsive force between the third magnetic member 63 and the second magnetic member 64, and when the hand is removed, the key cap 70 is lifted up by the repulsive force between the second magnetic member 64 and the third magnetic member 63.
As shown in fig. 8, when the slide plate 30 slides to the second setting position, the third magnetic member 63 approaches the second magnetic attraction member and moves away from the second magnetic member 64, and at this time, the repulsive force between the third magnetic member 63 and the second magnetic member 64 is smaller than the attraction force of the third magnetic member 63 to the second magnetic attraction member, and the key cap 70 is locked at the pressed position by the attraction force between the third magnetic member 63 and the second magnetic attraction member.
In order to simplify the structure of the whole device, in a specific embodiment, the sliding plate 30 is a plate-shaped structure made of a magnetic adsorbing material, and the second magnetic adsorbing member is integrated with the sliding plate 30. That is, in this case, the slide plate 30 is the second magnetic attraction member, thereby simplifying the structure of the entire apparatus.
As can be seen from the above description, in the present embodiment, by adjusting the position of the second magnetic member 64, when the second magnetic member 64 repels the third magnetic member 63, a force for lifting the key cap 70 is provided, and when the second magnetic member 64 attracts the second magnetic member, the key cap 70 is locked at the pressed position.
