The bottom shell of some existing keyboards is provided with a pivotable support leg, which can reach the supporting position after the leg is turned outward, and the inclination angle of the keyboard is increased; The whole is stored in the concave position of the bottom case, and the inclination angle of the keyboard is small.

The tilting feet meet the needs of different use angles, but the setting of the tilting feet increases the height of the bottom shell of the keyboard. When designing a thin keyboard, the thickness of the keyboard is limited and the inclination angle of the keyboard is desired to be adjustable. Swing feet.

SUMMARY OF THE INVENTION

The first object of the present invention is to provide a plug-in support foot component for a keyboard that occupies less space and meets the thickness requirement and can realize adjustable keyboard inclination.

The second object of the present invention is to provide a keyboard which can meet the thickness requirement and can realize adjustable keyboard inclination.

The plug-in foot component of the keyboard provided by the first object of the present invention includes a main body, a first support body and a second support body; in the extension direction, the main body includes opposite first sides and second sides, and the first support body is along the extension direction. Protruding from the first side, the second support body protrudes from the second side along the extending direction; in the extending direction, the first support body has a first size, the second support body has a second size, and the second size is smaller than the first size Dimensions; the plug-in leg part can be changed between the first support state or the first support state; when the plug-in leg part is in the first support state, the first support body is used as the support end; when the plug-in leg part is in the second support state , the second support body is used as the support end.

It can be seen from the above solution that the plug-in leg part, as a detachable part, can be inserted into the socket of the bottom case in two opposite directions, so that the first support body or the second support body of the plug-in leg part protrudes from the bottom. The shell is also used as the support end; because the heights of the first support body and the second support body are different, the state of the first support body and the second support body as the support end makes the keyboard present different inclination angles. In addition, the second support body can be set to a relatively small height, and in the use state of the second support body as the support end, the degree of outward convexity of the plug-in leg parts is small, which is beneficial for accommodating the keyboard. The area and thickness occupied by the plug-in foot parts and the sockets of the bottom case are small, which is beneficial to meet the thickness design requirements and the inclination angle adjustment requirements of the thin keyboard.

A further solution is that, on the projection of the extending direction, the second support body is located on the outer periphery of the first support body.

A further solution is that, on the projection of the extending direction, the second support body surrounds the outer circumference of the first support body.

As can be seen from the above, since a first accommodating space and a second accommodating space that are respectively matched with the first support body and the second support body need to be formed in the socket of the bottom case, there is a space between the second support body and the first support body. When spaced apart, the first accommodating space and the second accommodating space can form an annular baffle wall, which can not only limit and cooperate with the first support body or the second support body, but also abut with the main body in the extending direction, increasing the Great support strength.

A further solution is that the surface of the first support body is spherical.

It can be seen from the above that in addition to meeting the appearance requirements, the spherical crown or hemispherical support body is more conducive to bear the horizontal force and the gravitational force at the same time. It can make the foot parts have a more stable mechanical state and prolong the service life.

A further solution is that a matching protrusion is formed on the outer peripheral surface of the main body.

It can be seen from the above that when the plug-in leg part is made of soft material, the matching protrusion can enhance the insertion stability of the plug-in leg part, and at the same time, it will not increase the difficulty of disassembly and assembly too much.

The keyboard provided by the second object of the present invention includes a bottom case and a plug-in support foot part, a socket is formed on the bottom case, and the plug-in support foot part is inserted into the socket; the plug-in support foot part adopts the above-mentioned plug-in support foot part; The support leg is inserted into the jack in a first support state, the second support body is located in the jack, and the first support body protrudes out of the bottom shell; Among them, the first support body is located in the socket, and the second support body protrudes from the bottom case.

It can be seen from the above solution that since the heights of the first support body and the second support body are different, the state of the first support body and the second support body as support ends causes the keyboard to present different inclination angles. The structure of the socket for inserting the supporting leg part and the bottom case is simple, and the occupied area and thickness are both small, and the thickness design requirements and the inclination angle adjustment requirements of the thin keyboard are satisfied.

A further solution is that the jack includes a main body accommodating space, a first accommodating space and a second accommodating space, the main body accommodating space is communicated with the first accommodating space along the extension direction, and the main body accommodating space and the second accommodating space are communicated along the extension direction; The support foot component is inserted into the jack in the first support state, and the second support body is located in the second accommodating space; when the support foot component is inserted into the jack in the second support state, the first support body is located in the first support body. within the accommodation space.

A further solution is that the second accommodating space surrounds the outer circumference of the first accommodating space.

A further solution is that an annular baffle wall is formed between the first accommodating space and the second accommodating space; the annular baffle wall restricts the main body in the extending direction.

It can be seen from the above that the main body accommodating space, the first accommodating space and the second accommodating space respectively accommodate the main body, the first supporting body and the second supporting body. Cartridge foot components are all tighter fit between each other.
