The disclosed embodiments provide a key assembly. The key assembly may be used in a display device. As shown in fig. 1, 3 to 5, the display device may include a housing 2. The housing 2 may be provided with a key hole 203. The key assembly may include a key support 3 and keys 1, wherein:

the key holder 3 can be supported in the housing 2. The key holder 3 is provided with a strip-shaped hole 301. The length direction of the strip-shaped hole 301 is perpendicular to the axis of the key hole 203. The strip-shaped hole 301 can be sleeved on a positioning member 7 fixed in the housing 2, and is in sliding fit with the positioning member 7 in the length direction of the strip-shaped hole 301. The key 1 can be arranged on the key support 3 and can be matched with the key hole 203.

In the assembly process of the key assembly of the embodiment of the present disclosure, a positioning member 7 is fixed in the casing 2 of the display device, and the strip-shaped hole 301 and the positioning member 7 are in sliding fit in the length direction of the strip-shaped hole 301, and the length direction of the strip-shaped hole 301 is perpendicular to the axis of the key hole 203, so that the key support 3 can move in the direction perpendicular to the axis of the key hole 203, and thus the position of the key support 3 can be adjusted to avoid the key 1 from having bad interference with the key hole 203, prevent the key 1 from being locked, and avoid affecting the use of the key 1; meanwhile, the position of the key support 3 is adjusted, so that the key 1 can be aligned with the key hole 203, and the key 1 can be conveniently installed in the key hole 203.

The following describes each part of the key assembly according to the embodiment of the present disclosure in detail:

as shown in fig. 3 to 5, the key holder 3 may be provided with a strip-shaped hole 301. Wherein, the key holder 3 may comprise a base 302. The bar-shaped hole 301 may be formed in the base 302. The length direction of the strip-shaped hole 301 is perpendicular to the axis of the key hole 203. The cross section of the bar hole 301 perpendicular to the axis of the bar hole 301 is taken as the bar hole 301 cross section. Wherein, the length direction of the cross section of the strip-shaped hole 301 is the length direction of the strip-shaped hole 301; the width direction of the cross section of the bar hole 301 is the width direction of the bar hole 301. Since the pressing direction of the key 1 is parallel to the axis of the key hole 203, the extending direction of the strip-shaped hole 301 is perpendicular to the pressing direction of the key 1. In addition, the axis of the bar-shaped hole 301 may be parallel to the axis of the key hole 203. Of course, the axis of the bar-shaped hole 301 may be perpendicular to the axis of the key hole 203, and the bar-shaped hole 301 and the positioning member 7 are slidably engaged in the axis direction of the bar-shaped hole 301 to improve the degree of freedom of the key 1 in the direction perpendicular to the axis of the key hole 203, so as to improve the degree of freedom of the key 1 connected to the key holder 3 in the direction perpendicular to the axis of the key hole 203, and further, to more conveniently align the key 1 with the key hole 203. The positioning member 7 may be a cylindrical member, but the embodiment of the present disclosure is not limited thereto. One end of the positioning member 7 is fixed to the housing 2, and the other end thereof has a stopper. The size of the limiting part in any direction perpendicular to the axis of the strip-shaped hole 301 is larger than the opening of the strip-shaped hole 301, so that the positioning piece 7 is prevented from being released from the strip-shaped hole 301. For example, the post may be a stop screw or the like. The number of the bar-shaped holes 301 may be multiple, and at least two bar-shaped holes 301 are distributed at two ends of the key holder 3 along a direction perpendicular to the axis of the key hole 203, for example, may be distributed at two ends of the base 302. In addition, the base 302 may include a bottom plate. The bar-shaped hole 301 may be formed at an edge of the bottom plate, and one end of the bar-shaped hole 301 along a length direction thereof may be an open end.

As shown in fig. 5 to 8, the key holder 3 of the present disclosure may include an arch 303 and a support plate 304. The arch 303 is provided in the base 302 of the key-holder 3. The axis of the dome 303 extends in the axial direction of the key hole 203. The arch 303 includes a first end and a second end along the axial direction of the arch 303. The support plate 304 may be provided at the second end of the arch 303. The key 1 may be inserted through the support plate 304 and located inside the arch 303. The supporting plate 304 may be perpendicular to the axis of the key hole 203, that is, the supporting plate 304 is perpendicular to the pressing direction of the key 1. The base 302, the arch 303, and the support plate 304 may be integrally formed, but the disclosure is not limited thereto. The key assembly of the disclosed embodiment may further include a key circuit board 4. The key circuit board 4 may be provided at a first end of the arch 303 and disposed opposite the support plate 304. The keys 1 can pass through the arch 303 to mate with the key circuit board 4. Specifically, the key 1 can be brought into contact with the key circuit board 4 when pressed. The key circuit board 4 may be parallel to the supporting board 304, so that the key circuit board 4 is perpendicular to the pressing direction of the key 1. The key circuit board 4 may be removably attached to the first end of the arch 303. For example, the first end of the arch 303 is provided with a buckle 306, and the key circuit board 4 is provided with a card slot 401. The latch 306 cooperates with the latch slot 401 to latch the key circuit board 4 to the first end of the arch 303. Further, the key circuit board 4 may include opposite first and second surfaces. The first surface may have key contacts thereon. The second surface may be provided with a connector 5 for connection to an external circuit. The key 1 can be arranged on one side of the first surface of the key circuit board 4 far away from the second surface, and the orthographic projection of the key 1 on the first surface is superposed with the key contact.

As shown in fig. 5-8, the key assembly of the present disclosure may further include a resilient arm 6. The elastic arm 6 may be disposed between the key circuit board 4 and the supporting plate 304 and parallel to the supporting plate 304. One end of the elastic arm 6 can be fixed on the key support 3, and the other end can be connected to the key 1. When the key 1 is pressed, the elastic arm 6 is deformed by the pressing force, so that the key 1 moves towards the key circuit board 4, and the key 1 is contacted with the key contact; after the key 1 is released, the elastic arm 6 is elastically reset, so that the key 1 is separated from the key contact. The elastic arm 6 may extend along a wavy line, but the embodiment of the present disclosure is not limited thereto. The number of resilient arms 6 may be one, two, four or more. The key holder 3 of the present disclosure may further include a mounting plate 307. The mounting plate 307 may be perpendicular to the axis of the key hole 203 and connected between the second end of the arch 303 and the support plate 304. The key 1 passes through the mounting plate 307. The side of the mounting plate 307 facing the key circuit board 4 may be provided with a protrusion. The elastic arm 6 is located between the mounting plate 307 and the key circuit board 4, and one end of the elastic arm 6 may be connected to the protruding portion of the mounting plate 307 and the other end is connected to the outer circumferential surface of the key 1. The base 302, the arch 303, the mounting plate 307, and the supporting plate 304 of the key holder 3 may be integrally formed, but the disclosure is not limited thereto.
