Detailed Description

For a further understanding of the objects, construction, features and functions of the utility model, reference should be made to the following detailed description of the preferred embodiments.

Referring to fig. 1A and 1B, fig. 1A is a top view of a keyboard structure 10 according to an embodiment of the utility model. Fig. 1B is a schematic bottom view of the keyboard structure 10 shown in fig. 1A and an enlarged schematic partial structure thereof. Wherein the keyboard structure 10 comprises a keyboard body 100 and at least one support foot 110. In the present embodiment, the keyboard structure 10 includes two support legs 110, and the two support legs 110 are movably mounted at the bottom of the keyboard body 100.

Specifically, the keyboard body 100 has an upper case 101, a bottom case 102, and a plurality of keys 103. The plurality of keys 103 are disposed inside the bottom case 102, the upper case 101 is covered above the bottom case 102, the plurality of keys 103 are fixed between the upper case 101 and the bottom case 102, and the key cap 103a of each key 103 extends from one of the plurality of key openings 101a of the upper case 101 to above the surface 101S of the upper case 101, so that a user can generate a trigger signal corresponding to the character symbol 103b of each key 103 by pressing different key caps 103a, and further output a text, a symbol, or a special action corresponding to the character symbol 103b of the key 103 to a controller (not shown) of the electronic device.

The bottom case 102 of the keyboard body 100 has a back surface 102b and at least one (e.g., two) receiving grooves 102a concavely disposed on the bottom surface 102b, and each supporting leg 110 is movably disposed in the corresponding receiving groove 102 a. For example, in the present embodiment (as shown in fig. 1B), each supporting leg 110 may be rotatably pivoted in the corresponding accommodating groove 102a by the pivot 114.

When the supporting leg 110 is in the storage state, the supporting leg 110 is stored in the storage groove 102 a. When the keyboard is to be switched to the supporting state, the user can pull the supporting leg 110 to rotate relative to the bottom surface 102b, so that the supporting leg 110 moves to the outside of the accommodating groove 102a and contacts with the bearing surface (e.g., a desktop (not shown)) to adjust the inclination degree of the keyboard body 100 and the bearing surface (not shown).

Referring to fig. 1A, fig. 1B, fig. 2A to fig. 2C, fig. 2A is an exploded structure diagram of the supporting leg 110 according to an embodiment of the utility model. Fig. 2B is a top view illustrating an assembled state of the assembly structure of the supporting leg 110 according to fig. 2A. Fig. 2C is a bottom schematic view of the assembly structure of the supporting leg 110 shown in fig. 2B.

In the present embodiment, the support leg 110 includes a main body and an outer cover 113, and the outer cover 113 is coupled to the main body. The main body portion further includes a foot body 111 and two elastic arms (an elastic arm 112a and an elastic arm 112 b). The foot body 111 has an upper surface 111t, a rear surface 111b, and two side surfaces (side surface 111S1 and side surface 111S 2). The back surface 111b is located on the opposite side of the upper surface 111 t. The two side surfaces 111S1 and 111S2 are opposed in parallel to each other and are connected to the upper surface 111t and the rear surface 111b, respectively.

The two elastic arms 112a and 112b are disposed in parallel on two sides of the foot body 111, for example, symmetrically disposed with respect to the foot body 111, and the two elastic arms 112a and 112b are respectively adjacent to two sides 111S1 and 111S2 of the script body 111, for example, the elastic arm 112a is adjacent to the side 111S1 of the script body 111, and the elastic arm 112b is adjacent to the side 111S2 of the script body 111. An opening 116 is provided between the two elastic arms 112a and 112b and the sides 111S1 and 111S2 of the script body 111, respectively. And one end of each of the elastic arms 112a and 112b is connected to the foot body 111 through a connection portion 115; the other end of each elastic arm (elastic arms 112a and 112 b) is provided with a pivot 114.

Wherein each pivot 114 extends outwardly from a corresponding spring arm (spring arms 112a and 112 b), respectively, in a direction away from the foot body 111. The directions of extension of the two pivots 114 are parallel so that the central axes of the two pivots 114 are parallel. In some embodiments, the central axes of the two pivots 114 coincide. And the extending direction of each pivot 114 (for example, the direction parallel to the X axis) is perpendicular to the extending direction of the elastic arms 112a and 112b (for example, the direction parallel to the Y axis) and perpendicular to the normal V of the back surface 111b of the script body 111.

As shown in fig. 1B, each pivot 114 is pivoted in a pivot hole 102p in the corresponding accommodating groove 102a of the bottom shell 102. When the supporting leg 110 is in the storage state, the back 111b of the script body 111 faces the bottom surface 102r of the accommodating groove 102a, even the back 111b of the leg body 111 is adhered to the bottom surface 102r of the accommodating groove 102a of Ji Rong, and the surface of the supporting leg 110 exposed from the accommodating groove 102a is parallel and coplanar with the bottom surface 102b of the bottom shell 102, thereby storing the entire supporting leg 110 in the accommodating groove 102 a. When the supporting leg 110 is switched to the supporting state, the supporting leg 110 may be rotated to protrude from the bottom surface 102b of the bottom case 102. And with the movement (e.g., rotation) of the supporting leg 110, a variable angle Ɵ other than 180 ° can be formed between the back surface 111b of the script body 111 and the bottom surface 102b of the bottom case 102 (or the bottom surface 102r of the accommodating groove 102 a).

The cover 113 may be a half-shell structure that covers the upper surface 111t of the script body 111 and the elastic arms 112a and 112b (i.e., covers the main body portion) in the accommodated state, thereby shielding the two openings 116 between the two elastic arms 112a and 112b and the sides 111S1 and 111S2 of the script body 111. In the accommodated state, the outer cover 113 also covers the upper surfaces 112S and the outer side surfaces 112O of the elastic arms 112a and 112b, respectively, simultaneously, that is, the outer cover 113 covers three continuous surfaces simultaneously; in other words, the outer cover 113 covers both the openings 116, and two gaps 119 formed between the two elastic arms (the elastic arms 112a and 112 b) and the two side walls 102v of the accommodating groove 102a of the bottom case 102, respectively. Thus, dust and foreign matters can be prevented from invading and accumulating in the two openings 116, so that the movement (such as rotation) of the supporting leg 110 is not hindered by the dust and foreign matters, and the normal rotation and opening and closing of the supporting leg 110 are ensured.

In an embodiment of the utility model, at least one card hole 111O is disposed on the upper surface 111t of the script body 111, as shown in fig. 2A to 2C, in this embodiment, the card hole 111O is a through hole, but not limited thereto, and the card hole 111O may also be a blind hole. Correspondingly, the outer cover 113 is provided with a hook 113a, and the outer cover 113 can be clamped in one of the clamping holes 111O on the script body 111 by the hook 113a, so that the outer cover 113 and the script body 111 are tightly combined. The user can select the engaging hole 111O engaged with the hook 113a according to the actual requirement (e.g. the requirement of supporting height, etc.). The arrangement of the hook 113a and the hole 111O is not limited thereto. In another embodiment of the present disclosure, the hooks may be disposed on the leg body 111, and the fastening holes may be disposed on the outer cover 113 correspondingly.

In addition, in an embodiment of the present utility model, the outer cover 113 may be movably (e.g., slidably) provided on the main body portion; meanwhile, the hook 113a and the hole 111O are used as a limiting member to limit the sliding range of the outer cover 113 on the main body, so as to meet the actual use requirement of the user.

For example, referring to fig. 3, fig. 3 is a schematic diagram illustrating another assembled state of the outer cover 113 and the main body in the supporting leg 110 of fig. 2A.

In the present embodiment, the foot body 111 has a plurality of card holes 111O thereon, and the plurality of card holes 111O are aligned along an extending direction (e.g., a direction parallel to the Y axis) parallel to the side surfaces 111S1 and 111S2. The user can select one of the plurality of engaging holes 111O to engage the engaging hook 113a of the outer cover 113 therein, thereby determining the overlapping area of the outer cover 113 and the main body, and adjusting the overall length of the supporting leg 110.

In an embodiment of the present utility model, the user can drag the outer cover 113 outwards in parallel, so that the hook 113a of the outer cover 113 is engaged in the engaging hole 111O far from the pivot 114, thereby reducing the overlapping area of the outer cover 113 and the main body. At this time, the portion of the cover 113 not overlapping the main body portion may be extended outward, increasing the overall length of the support leg 110. Particularly, when the supporting legs 110 are switched to the supporting state, the inclination degree of the keyboard body 100 and the bearing surface (not shown) can be adjusted.

In order to ensure the stability of the outer cap 113 when it is pulled outward, in an embodiment of the present utility model, a guide groove 117 may be provided on one of the body portion and the outer cap 113; a guide rail 118, which is matched with the guide groove 117, is provided on the other of the main body and the outer cover 113, and serves to guide the outer cover 113 to slide on the main body. In the embodiment shown in fig. 2A, the guide groove 117 is disposed on the side of the outer side surface 112O of the elastic arm of the main body, and the guide rail 118 is disposed on the outer cover 113, but not limited thereto.

In practice, in one embodiment, one of the main body and the outer cover 113 may have a limiting member thereon, where the limiting member may be used to limit the range in which the outer cover 113 can slide on the main body. In another embodiment, one of the main body and the outer cover 113 may have a first limiting member, and the other of the main body and the outer cover 113 may have a second limiting member, where the first limiting member and the second limiting member cooperate to limit the sliding range of the outer cover 113 on the main body. The sliding range can be limited by a user according to actual requirements.

In the foregoing embodiments and the foregoing drawings, the outer cover 113 covers the three continuous surfaces of the elastic arms 112a/b and the script body 111 at the same time in the storage state, but the utility model is not limited thereto. For example, one U-shaped cover 113 may cover the gap 119 between the elastic arms 112a/b and the side wall 102v of the receiving groove 102a alone. Alternatively, when the outer side surface 112O of the elastic arm 112a/b extends outward to eliminate the gap 119 with the side wall 102v of the accommodating groove 102a, the outer cover 113 may no longer need to cover the outer side surface 112O of the elastic arm 112a/b, and the area of the outer cover 113 may cover only the two openings 116; at this time, the guide groove 117 and the guide rail 118 may be provided on the upper surface 111t of the script body 111 and/or the upper surface 112S of the elastic arm 112 a/b.

In actual operation, in another embodiment, the keyboard structure 10 includes at least two supporting legs movably mounted at the bottom of the keyboard body, which is different from the above embodiment in that the bottom shell of the keyboard body has a back surface, and the back surface may not be provided with a receiving groove, but the supporting legs 110 are directly disposed on the back surface. At this time, the pair of elastic arms on the main body part can be directly pivoted to the keyboard body (such as the bottom shell), so that the supporting legs can rotate reciprocally to support the keyboard body or be accommodated in the bottom surface of the keyboard body. Because the supporting legs are directly arranged on the back surface, no gap exists between the supporting legs and the back surface and between the elastic arms and the side wall of the accommodating groove, and the outer cover is fixed on the upper surface of the main body part and can only cover the opening between the script body and the two elastic arms, so that dust is prevented from invading and accumulating at the opening, the supporting instep side or the pivoting position.

According to the above embodiments, a keyboard structure is provided, which includes a keyboard body and a movable supporting leg. By arranging the outer cover on the body part of the supporting leg, the supporting leg can cover at least one gap between the body part exposed by the body part and the accommodating groove or at least one opening on the body part in a storage state, so that dust invasion and accumulation are prevented, and the supporting leg can be further ensured to normally rotate and open and close. Furthermore, the outer cover can selectively slide relative to the body part to change the supporting height in the supporting state. Furthermore, when the keyboard body is not provided with the accommodating groove, the supporting legs can be directly arranged on the bottom surface of the keyboard body; at this time, the outer cover can still cover at least one opening on the supporting leg, so that dust is prevented from invading and accumulating on the back side or the pivoting position of the supporting leg.

Of course, the present utility model is capable of other various embodiments and its several details are capable of modification and variation in light of the present utility model by one skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
