Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.Below in conjunction with the accompanying drawings this utility model is described further.
As shown in Figures 1 to 5, a kind of keycap bascule, including the gimbal lever 40, pair of brackets 10, keycap 30, for substrate 20 and the switch 50 of fixed support 10.
As shown in Figure 4 and Figure 5, the inner side of substrate 20 is provided with holding tank 202 along its length, in pair of brackets 10 is fixed on holding tank 202 and be positioned at holding tank 202 both sides.As it is shown in figure 1, the first stopper section 101 that support 10 extends by initial end to the left, upwardly extending second stopper section 102, the 3rd stopper section 103 extended to the right and the 4th stopper section 104 downwardly extended form；First stopper section 101, the second stopper section 102, the 3rd stopper section 103 and the 4th stopper section 104 surround a chute 106, and the 3rd stopper section 103 upper surface is extended with the cross axle 107 being connected with keycap 30.As shown in Figure 3 and Figure 4, the gimbal lever 40 includes mobile jib portion 401, by a pair side lever portion 402 of mobile jib portion 401 end bending and formed and the secondary bar portion 403 parallel with mobile jib portion 401 by the bending of side lever portion 402 end respectively, in secondary bar portion 403 is respectively arranged in the chute 106 of support 10 and in chute 106 slidably, substrate 20 is provided with the buckling groove 201 being flexibly connected with mobile jib portion 401, in mobile jib portion 401 is connected in buckling groove 201 and it is rotatably connected with buckling groove 201, in switch 50 is installed on holding tank 202 and between pair of brackets 10, keycap 30 is located at the top of switch 50 and abuts switch 50；The surface of substrate 20 is provided with the limiting plate 60 being positioned at immediately below keycap 30, and during pressing keycap 30, keycap 30 medial surface abuts the surface of limiting plate 60.
Specifically, as shown in Figure 4 and Figure 5, buckling groove 201 may be disposed at the front or back of basic 20.Substrate 20 upper surface is provided with the fixed mount 205 for fixed support 10.Fixed mount 205 is fixing with the inwall of holding tank 202 to be connected, and fixed mount 205 and holding tank 202 can be integral structures.Substrate 20 is provided with limited block 203 away from the one side of keycap 30, and mobile jib portion 401 is when buckling groove 201 rotates, and limited block 203 is used for limiting side lever 402 and screws out in holding tank 202.When keycap 30 medial surface abuts switch 50, the height of limiting plate 60 to substrate 20 is less than the height of keycap 30 medial surface to substrate 20.Limiting plate 60 is connected for removable with substrate 20, and substrate 20 upper surface can arrange a draw-in groove, and limiting plate 60 inserts draw-in groove and forms removable connection with substrate 20.
As shown in Figure 4 and Figure 5, during pressing keycap 30, keycap 30 act on the pair of brackets 10 of both sides in holding tank 202 simultaneously, and keycap 30 is played and supports and balanced action by pair of brackets 10.After keycap 30 is pressed and abutted with switch 50, the surface of limiting plate 60 abuts the inwall top of button cap 30, it is therefore prevented that keycap 30 presses the overweight impact to the circuit board in keyboard, decreases the damage of circuit board, extends the service life of circuit board.Limiting plate 60 is connected for removable with substrate 20, when installing the gimbal lever 40 with support 10, the opening 105 of secondary bar portion 403 alignment bracket 10 also slips into chute, after the gimbal lever 40 and support 10 install, limiting plate 60 fixedly mounts with substrate 20 again, and limiting plate 60 is possible to prevent secondary bar portion 403 to depart from chute 106.
As shown in Figure 1 and Figure 4, there is a breach 105 between the first stopper section 101 and the 4th stopper section 104, secondary bar portion 403 is slipped in chute 106 by breach 105.The end face of the first stopper section 101 is a face tilted to left down, the end face of the 4th stopper section 104 is the face of a lower inclination to the right, first stopper section 101 is additionally provided with boss at breach 105, and the secondary bar portion 403 that boss slides in can preventing chute 106 skids off from breach 105.Owing to the first stopper section 101 exists elasticity, when the gimbal lever 40 and support 10 are installed, the secondary bar portion 403 of the gimbal lever 40 side be pressed on support 10 the first stopper section 101 lateral surface and from breach 105 snap in opening chute 106, after the secondary bar portion 403 of the gimbal lever 40 both sides snaps in the opening chute 106 of pair of brackets 10, the first stopper section 101 returns to the original form.When pressing keycap 30, pair of brackets 10 is down pressed by keycap 30 simultaneously, and now slide in opening chute 106 in the secondary bar portion 403 of the gimbal lever 40 both sides, produces when being therefore possible to prevent keycap 30 to press.
Another embodiment, a kind of keyboard, including at least one keycap bascule.
It is above detailed description of the invention of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
