The input equipment mainly comprises a key 1, a printed circuit board film 2, a bottom plate 3 and a connecting piece 4, wherein the key 1 is a part which can be lifted up and down and is pressed by a user, the printed circuit board film 2 is positioned at the bottom of the key 1 and is arranged on the bottom plate 3, when a keycap 101 of the key 1 is pressed by the user and descends, the key 1 can be contacted with the printed circuit board film 2, and different keys 1 are contacted with different parts of the printed circuit board film 2, the printed circuit board film 2 can generate different information signals to be transmitted to electronic equipment, the bottom plate 3 is a bearing part of the key 1 and the printed circuit board film 2, namely the key 1 is supported on the bottom plate 3, the printed circuit board film 2 is laid on the bottom plate 3, the additionally arranged connecting piece 4 is also connected with the bottom plate 3, the connecting piece 4 is used for realizing the connection of the bottom plate 3 and an auxiliary part, and the connection mode is bonding.
In the structure, the connecting piece 4 is additionally arranged, and the connecting piece 4 is bonded with an auxiliary component of a notebook computer, so that the installation of the bottom plate 3, the printed circuit board film 2 and the keys 1 on the auxiliary component can be realized, because the component and the auxiliary component are bonded in a connecting mode, a threaded hole for connecting a bolt does not need to be formed in the auxiliary component, the threaded hole does not need to have enough depth for ensuring the connection reliability with the bolt, the auxiliary component does not need to have larger thickness, the unreliability caused by no bolt fixing is avoided, the thickness of the auxiliary component can be reduced to realize the thinning, in the assembling process, the existing auxiliary component can be adapted by a keyboard module, for example, the auxiliary component is a C-face shell of the notebook computer, the service life is prolonged while the thinness and the thinness are increased as much as possible, meanwhile, the thickness of the auxiliary component is reduced, the material consumption is reduced, the cost is reduced while the reliable assembly of the components of the input equipment is realized, and the miniaturization of the input equipment is also realized.
Wherein, because the thickness of the auxiliary member is reduced, the increase in the overall thickness of the input device due to the addition of the connecting member 4 is offset by the reduction in the thickness of the auxiliary member, i.e., the increase in the overall thickness due to the addition of the connecting member 4 is smaller than the reduction in the thickness of the auxiliary member, so that the overall thickness of the input device is reduced, i.e., the input device can be made thinner and lighter as a whole.
In the present embodiment, it is preferable that the connecting member 4 and the chassis 3 are respectively located on both sides of the printed circuit board film 2, and the printed circuit board film 2 is pressed by fitting to fix the printed circuit board film 2, as shown in fig. 1. With such an arrangement, not only can the connection with the auxiliary component as the housing 5 be facilitated (detailed description in the following contents), but also the fixation of the printed circuit board film 2 on the bottom plate 3 can be realized, so that the connecting member 4 has multiple functions, and it is not necessary to specially arrange a component for fixing the printed circuit board film 2, so that the structure of the input device is simpler, the difficulty required for assembly is reduced, and the thinned design is facilitated.
As shown in fig. 3, the auxiliary component is preferably a housing 5 covering the key 1, the printed circuit board film 2, the bottom plate 3 and the connecting piece 4, and the key 1, the printed circuit board film 2 and the bottom plate 3 are mounted in the housing 5 and the key cap 101 of the key 1 protrudes relative to the housing 5 by the adhesion of the connecting piece 4 to the inner wall of the housing 5. The auxiliary component in this embodiment may be a component of the input device, such as the housing 5, which can affect the overall thickness, and when the input device is a keyboard integrated with a notebook computer, the housing 5 is a part of the housing of the notebook computer for mounting the keyboard. In this case, since the keyboard, the printed circuit board film 2 and the bottom plate 3 are mounted on the housing 5 from bottom to top, that is, the housing 5 is located at the top of the keyboard, the printed circuit board film 2 and the bottom plate 3, in order to facilitate the connection between the bottom plate 3 and the housing 5 and to minimize the thickness of the connecting member 4, it is preferable that the connecting member 4 is disposed at the top of the bottom plate 3 and above the printed circuit board film 2 to be as close as possible to the housing 5, thereby enhancing the structural compactness of the input device.
Preferably, the link 4 comprises a grid portion, and the key cap 101 of the key 1 passes through the through hole 6 of the grid portion, as shown in fig. 1, 2 and 5. In the present embodiment, the connector 4 is preferably a plate-like member and forms a laminated structure with the printed circuit board film 2 and the chassis 3. Moreover, since the link 4 is disposed on the printed circuit board film 2, in order to ensure that the key cap 101 can normally extend out of the housing 5 to enable a user to operate the same, the portion of the link 4 aligned with the key 1 is configured to be a grid structure, the key cap 101 of the key 1 passes through the through hole 6 of the grid, and the edge portion of the link 4 surrounding the grid portion is still preferably a plate-like structure, so as to increase the connection area of the link 4 with the bottom plate 3 and the housing 5, and improve the connection firmness.
More preferably, as shown in fig. 4-6, the number of the through holes 6 is the same as that of the keycaps 101, and the shapes of the through holes 6 are matched with those of the keycaps 101 one by one, so that the plurality of through holes 6 passing through the grid part of the keycaps 101 one by one can make the connecting piece 4 fit with the key 1 more closely. In addition, the number of the through holes 6 can be less than that of the keys 1, and a plurality of keys 1 which are arranged close to each other can penetrate through the same through hole 6 with a larger area, so that the matching of the connecting piece 4 and the keys 1 can be realized.
Further, the connecting portion of the connecting member 4 and the auxiliary member is plural, and the connecting portion is located around each key cap 101 and/or an edge of the connecting plate. That is, in addition to the link 4 having the mesh portion, since the through holes provided in the case 5 for extending the key caps 101 are also matched with the number and shape of the key caps 101, as shown in fig. 5 and 6, in order to further increase the bonding area and enhance the bonding firmness, it is preferable to coat the glue 7 not only on the peripheral edge portion of the link 4 but also on the portion between any two adjacent through holes 6 (i.e., the surface of the strip portion forming the mesh, as shown in fig. 4 and 5), thereby maximizing the bonding area and enhancing the bonding firmness of the link 4, the base plate 3, the printed circuit board film 2, and the key 1 on the case 5. Further, the adhesive 7 may be applied to the inner wall of the case 5 at a portion contacting the connector 4.
Specifically, the connecting member 4 is preferably made of metal or plastic, and the housing 5 is preferably made of metal. The selection of the above-mentioned material not only can improve the structural strength or save the cost, but also can enhance the fastness of bonding, so it is preferable.

Specifically, as shown in fig. 2 and 3, the key 1 includes a scissors structure 102, and the key cap 101 is supported on the base plate 3 by the scissors structure 102. In the present embodiment, the key cap 101 is supported on the base plate 3 by using the scissors structure 102, so that the key cap 101 can be lowered when pressed by a user and can be raised to the home position after the pressing force is removed, thereby ensuring the normal operation of the input device. The scissors structure 102 is adopted because the scissors structure 102 has a simple structure, a small volume, a large deformation amount, and a strong fatigue resistance, and is therefore a preferred structure of the present embodiment. In addition, the keyboard may be supported by other elastic members, such as springs, and may be lifted relative to the bottom plate 3.
In addition, the input device can further comprise a backlight module 8 arranged at the bottom of the bottom plate 3, and after the backlight module 8 is arranged, the input device can have colorful backlight after being electrified, so that the aesthetic feeling of the appearance of the input device is improved.
