Abstract
The utility model relates to computer keys, particularly a key balancing device which enables a user to press the keys forsooth. The key balancing device comprises keys, key caps and a base plate. The utility model is characterized in that a balance bar is respectively and transversely arranged at the inner front and the inner back sides of each of the key caps of the keys, pin joint parts which correspond to one another are respectively arranged on the base plate of a keyboard and in the key caps, and the two balance bars are in pin joint with the interior of each of the pin joint parts in the base plate and the key caps in a scissor crossover type. Force can always be transferred to the keys which are pressed at any angle, and the effect of forsooth pressing the keys is realized. The utility model is used for the keyboard.
Description
The utility model relates to the button on the keyboard.
Button on the existing keyboard, especially blank key, it mostly is strip, therefore must in this blank key, be provided with balance device, as shown in Figure 4: a side articulates a balance stem 71 in the blank key 7, balance stem 71 1 sides are articulated on the front side of blank key 7, and opposite side is oblique to be articulated on the base plate 72 of keyboard, so that be pressed onto a side of pivot joint when pushing blank key 7, pushing strength can transmit fully, really reach and push, but if not by to the side that is articulated the time, can cause transmission fully of strength, pushing can't be certain, the notebook computer of especially frivolous shape, because of the thickness of its keycap is all very thin, easier can't pushing really.
The purpose of this utility model provide a kind of button is reached push really by strong balance device.
The purpose of this utility model is achieved in that the button balance device, it comprises button, keycap and base plate, it is characterized in that: each laterally is provided with a balance stem front and back both sides of this balance device in the keycap of button, and respectively be provided with corresponding articulated section on the base plate of keyboard and in the keycap, and two balance stems are the scissors cross modal and are articulated in the articulated section set in base plate and the keycap.
Above-mentioned design, because the setting of balance stem makes button, no matter especially blank key from which kind of angle is pushed, strength can both be sent to and pass on the key, thereby reaches the effect of pushing really.
Below by drawings and Examples the utility model is described further again:
Fig. 1 is the utility model three-dimensional exploded view;
Fig. 2 is the utility model combination cross-sectional schematic;
Fig. 3 is another embodiment synoptic diagram of the utility model;
Fig. 4 is good for cross-sectional schematic for existing pressing;
As shown in Figure 1: the utility model comprises button, keycap 1 and base plate 3, it is characterized in that: each laterally is provided with a balance stem 2,2 ' the front and back both sides of this balance device 10 in the keycap 1 of button, and respectively be provided with corresponding articulated section 31 on the base plate 3 of keyboard and in the keycap 1, and two balance stems 2,2 ' are the scissors cross modal and are articulated in the articulated section 31 set in base plate 3 and the keycap 1.Wherein, button is the blank key of strip.Wherein, this balance stem 2 has one first pivoted pole, 21, the first pivoted poles, 21 both sides vertically to be bent with support bar 22, holds in addition in supported on both sides bar 22 inwardly to be bent to form second pivoted pole 23 that is parallel to each other with first pivoted pole 21 respectively again.Wherein, set articulated section 31 is a sliding tray on this base plate 3.Wherein, set articulated section 11 is a pickup groove in the keycap 1.
During assembling, two balance stems 2,2 ' first pivoted pole 21 are articulated in the sliding tray of base plate 3 respectively, balance stem 2,2 ' second pivoted pole 23 are articulated in respectively in this pickup groove, simultaneously, the bridge formation 4 on the keyboard also can be articulated together with keycap 1.When pushing blank key, the pivot 41 of building bridge on 4 can be to a side shifting, and second pivoted pole 23 also can be to a side shifting, the keycap of blank key is whole to be pushed downwards, and the extrusion flexible member, the circuit on the interior circuit board of flexible member and keyboard is contacted, and form conducting state.
As shown in Figure 3: wherein, this balance stem 2,2 ' the left and right sides are articulated movably mutually, promptly form scissorly to be articulated.The utility model, when no matter when any angle was pushed blank key, strength can both be communicated on the blank key, thereby reaches certain pushing, and has guaranteed keyboard operation, uses reliable, safe.
Claims (5)
1, button balance device, it comprises button, keycap and base plate, it is characterized in that: each laterally is provided with a balance stem front and back both sides of this balance device in the keycap of button, and respectively be provided with corresponding articulated section on the base plate of keyboard and in the keycap, and two balance stems are the scissors cross modal and are articulated in the articulated section set in base plate and the keycap.
2, button balance device as claimed in claim 1 is characterized in that: wherein, button is the blank key of strip.
3, button balance device as claimed in claim 1, it is characterized in that: wherein, this balance stem has one first pivoted pole, and the first pivoted pole both sides vertically are bent with support bar, holds in addition in the supported on both sides bar inwardly to be bent to form second pivoted pole that is parallel to each other with first pivoted pole respectively again.
4, button balance device as claimed in claim 1 is characterized in that: wherein, set articulated section is a sliding tray on this base plate.
5, button balance device as claimed in claim 1 is characterized in that: wherein, the left and right sides of this balance stem is articulated movably mutually, promptly forms scissorly to be articulated.
