The end of the contact 13 facing the containing groove 1110 of the feedback portion 111 is provided with a second groove 137, and the second elastic member 133 is provided in the second groove 137. Thus, the first groove 135 defines the position of the first elastic member 131, and the second groove 137 defines the position of the second elastic member 133. The key cap 15 has a first positioning pillar 141 opposite to the first groove 135, and the first positioning pillar 141 penetrates through the first elastic member 131. The bottom of the accommodating groove 1110 has a second positioning column 143 corresponding to the second groove 137, and the second positioning column 143 penetrates through the second elastic member 133. The first elastic member 131 is fixed to the first positioning post 141, and the second elastic member 133 is fixed to the second positioning post 143.
Furthermore, at least one notch 1111 is formed around the notch of the receiving groove 1110 of the feedback portion 111 and facing one end of the key cap 15, and the side wall of the contact 13 facing one end of the key cap 15 further has a protrusion 132 capable of being placed in the at least one notch 1111. The number of the notches 1111 is not limited in this embodiment, the number of the projections 132 corresponds to the number of the notches 1111, and the projections 132 are configured to strike the notches 1111 to generate a striking sound.
In the present embodiment, the side wall of the pressing shaft 151 of the key cap 15 has a guiding through hole 150, the groove wall of the receiving groove 1110 of the feedback portion 111 has a groove wall notch 1112 corresponding to the guiding through hole 150, the guiding through hole 150 communicates with the groove wall notch 1112, the side wall of the contact 13 has a guide pillar 134, and the guide pillar 134 penetrates through the groove wall notch 1112 and the guiding through hole 150. The guiding through hole 150 has a first guiding through hole 1501 and a second guiding through hole 1503 connected to the first guiding through hole 1501, the first guiding through hole 1501 is close to the keycap 15 and extends in a direction parallel to the moving direction of the keycap 15 relative to the base structure 11, the second guiding through hole 1503 is far from the keycap 15, and an included angle is formed between the extending direction of the second guiding through hole 1503 and the extending direction of the first guiding through hole 1501 (see fig. 4).
Fig. 6 to 7 are schematic views showing a first usage state and a second usage state of the key device of the present application. As shown in the drawings, in the present embodiment, when the key device 1 is not in use (see fig. 2 to 4), the key cap 15 is supported by the first elastic member 131 and the second elastic member 133. The protrusion 132 of the contact 13 is opposite to the notch 1111 of the slot 1110, and the protrusion 132 is located above the notch 1111 and staggered with respect to the notch 1111, that is, the protrusion 132 corresponds to the edge of the slot 1110 beside the notch 1111. In addition, the guide post 134 of the contact 13 is inserted through the groove wall notch 1112 and the guide through hole 150, and the guide post 134 is located at the second guide through hole 1503 of the guide through hole 150.
When the user presses the key device 1 (see fig. 6 and 7), the key cap 15 moves downward relative to the base structure 11, the key cap 15 compresses the first elastic member 131, the first elastic member 131 presses the contact element 13, and the contact element 13 presses the second elastic member 133 (see fig. 2). In addition, the pressing shaft 151 of the key cap 15 presses against the elastic unit 117, and the elastic unit 117 deforms to press against the corresponding signal transmission point on the circuit unit 115, thereby completing one signal transmission.
Meanwhile, the upper edge of the second guiding through hole 1503 of the pressing shaft 151 presses against the guiding post 134 of the contact 13, which is used to press the guiding post 134 to move along the upper edge of the guiding through hole 150, wherein the penetrating edge of the second guiding through hole 1503 of the guiding through hole 150 is an oblique edge from the bottom right to the top left, and the guiding post 134 can easily move from the bottom right to the top left when the pressing shaft 151 presses downward. The guide post 134 thus moves along the second guide through hole 1503 to the first guide through hole 1501.
Moreover, after the guide pillar 134 drives the contact 13 to rotate in the horizontal direction, the protrusion 132 of the contact 13 is driven to correspond to the upper portion of the notch 1111, and the protrusion 132 of the contact 13 enters the notch 1111 directly due to the pressing height of the key cap 15. Thus, the bump 132 hits the notch 1111, which generates a feedback sound on the one hand and a feedback tapping feeling on the other hand.
When the key device 1 is no longer pressed, the first elastic member 131 and the second elastic member 133 release the compression elastic force, so that the first elastic member 131 supports the key cap 15, the second elastic member 133 supports the contact member 13, and the contact member 13 supports the first elastic member 131 and the key cap 15, so that the first elastic member 131 and the second elastic member 133 support the height of the key cap 15 together, and the key cap 15 and the contact member 13 return to the original positions. Meanwhile, the elastic unit 117 in the housing 119 returns to the original state, and the elastic unit 117 supports the pressing shaft 151, thereby driving the key cap 15 upward.
The first elastic element 131 drives the key cap 15 to move upward, and simultaneously drives the lower side edge of the through hole of the guiding through hole 150 of the pressing shaft 151 to press against the guide post 134 of the contact 13, so as to press the guide post 134 to move along the lower side edge of the guiding through hole 150, and under the condition that the pressing shaft 151 is lifted, the guide post 134 can easily move from the upper left to the lower right. The guide post 134 thus moves along the first guide through hole 1501 to the second guide through hole 1503. Meanwhile, the contact 13 is also driven to rotate, and the protrusion 132 of the contact 13 is driven to move away from the notch 1111 to return to the original state (i.e. the key is not used). So that the keys can be used again. In this embodiment, the keys with feedback can also be applied to a keyboard, and the keyboard with feedback can also be applied to an electronic device, wherein the electronic device can be a computer, a notebook, or any electronic related device that can use a keyboard.
In summary, the technical solution according to the present application is improved according to the shortcomings of the prior art, most of the key feedback methods in the prior art rely on the design of the axis, which is too high in cost, and most of the feedback force of the key with the axis design is slightly insufficient. Therefore, the present application provides a key device, a keyboard and an electronic apparatus, which includes a base structure, a contact member and a key cap. The base structure is provided with a shell, the shell is provided with a positioning part and a feedback part, and the contact piece is movably arranged in the accommodating groove of the feedback part. The key cap is provided with a pressing shaft which is arranged on the positioning part and is linked with the contact piece; when the keycap moves relative to the shell of the base structure, the keycap drives the contact piece to impact the feedback part. When the contact piece and the feedback part collide with each other, a feedback sound is generated on one hand, and a feedback knocking hand feeling is generated on the other hand. Therefore, when a user presses the key, the feedback of the key can be beneficial to the user to have better use hand feeling, and meanwhile, the cost of the key with the feedback is lower compared with that of the key with the axis.
The above description is only an embodiment of the present application, and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement or the like made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
