Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4 of the specification, an embodiment of the present invention provides a key unit for a switch panel, where the key unit for the switch panel includes a key panel 100 disposed on a front cover 400 of the switch panel, a key main board 500 is disposed on an inner side surface of the front cover 400, and a first square hole for exposing a key 510 on the key main board 500 is disposed on the front cover 400. The side walls of the two sides of the key panel 100 are provided with the inverted buckle pieces 100a extending towards the front cover plate 400 and symmetrically arranged, the front cover plate 400 is provided with inverted buckle holes 400a corresponding to the inverted buckle pieces 100a, and the key main board 500 is provided with avoidance holes 500a avoiding the inverted buckle pieces 400 a.
A dome support 200 is disposed between the front cover 400 and the key panel 100, elastic support legs 200a extending outward from the center of the dome support 200 are disposed on the upper and lower sides of the dome support 200, and the elastic support legs 200a and the main body of the dome support 200 form an obtuse angle.
During assembly, the key panel 100 can be directly buckled on the front cover plate 400 through the inverted buckle sheet 100a, and the elastic sheet support 200 is pressed on the front cover plate 400 through the key panel 100; while the key panel 100 is buckled on the switch panel, the spring support 200 springs the key panel 100 outwards, so that the protrusion 100b on the key panel 100 is not contacted with the key 510; and the elastic supporting legs 200a can give the key panel 100 multi-point elastic support, so that when each region of the key panel 100 is pressed by the outside, a consistent reaction force can be applied to the outside, consistent pressing hand feeling of each position of the key panel 100 is ensured, and user experience is improved.
Compared with the prior art, the key unit provided by the utility model has a simple structure and is convenient to implement and popularize. Moreover, the consistent pressing feeling of each point of the key panel 100 can be ensured, and the user experience is improved.
In this embodiment, the fixing posts 400b are respectively protruded from two diagonal corners of the first square hole, the main body of the spring plate bracket 200 is provided with a second square hole corresponding to the first square hole, and the periphery of the second square hole is concavely provided with the fixing holes 200b corresponding to the fixing posts 400 b. Therefore, the positioning of the dome sheet support 200 can be realized through the matching of the fixing posts 400b and the fixing holes 200b, and the dome sheet support 200 is prevented from deviating from the center of the key panel 100.
In the present embodiment, a protrusion 100b corresponding to the key 510 is disposed at the center of the key panel 100, and the protrusion 100b passes through the first square hole and the second square hole and extends toward the key 510 on the key main board 500. When the key panel 100 is pressed toward the front cover 400 by an external force, the obtuse angle between the elastic support leg 200a and the deformable spring support 200 is increased, so that the protrusion 100b contacts the key 510 and triggers the key 510 to operate, and after the external force is removed, the key panel 100 returns to the original position under the elastic restoring force of the elastic support leg.
In the embodiment, an outer decoration plate 300 is disposed on the outer side of the key panel 100 to protect the key panel 100, and the switch panel is conveniently decorated by replacing the outer decoration plate 300 with different materials and colors according to application requirements.
