Description

Spring arm structure of switch panel Technical Field The present utility model relates to a switch panel, and more particularly, to a spring arm structure of a switch panel. Background The electronic switch panel has better aesthetic property, the design is more diversified, the electronic switch panel can be well adapted to the design style of various places, and along with the popularization of intelligent equipment, the electronic switch panel is also more popular and valued. The electronic switch panel mainly comprises a bottom box, a circuit board, a touch switch arranged on the circuit board and a key board for pressing the touch switch, and in order to enable the key board to be far away from the touch switch when the touch switch is not needed to be pressed, an elastic arm is arranged on the bottom box, so that the key board can be pushed away by the elastic arm while the requirement of a key can be met through deformation. The elastic arm on the existing electronic switch panel is long and is arranged at the position opposite to the edge angle of the key board, but when a user presses the key board, the applied acting force is not necessarily vertical to the key board, when the lateral acting force is large, the key board is likely to slide a small distance relative to the bottom box, so that the false impression of looseness of the key board is caused, and bad use experience is brought to the user. Disclosure of utility model The utility model aims to provide a switch panel spring arm structure capable of improving the installation strength of a key board so as to improve the working stability and the use feeling. The utility model discloses an elastic structure of a switch panel, which comprises a bottom box, a circuit board provided with touch switches and a key board used for pressing the touch switches, wherein the bottom box is provided with a plurality of key boards which are arranged on the bottom box, the touch switches are arranged at the positions opposite to the middle parts of the key boards on the circuit board, the positions, opposite to the touch switches, of the bottom frame are respectively provided with a yielding hole, two opposite sides of the chassis, which are positioned in the yielding holes, are respectively provided with elastic arms, each elastic arm comprises an elastic rod, one end of each elastic rod is fixedly arranged on the bottom frame, the other end of each elastic rod extends towards two sides and is provided with a supporting rod, a positioning hole is formed in each supporting rod, a pressing column is arranged at the position, opposite to each supporting rod, of the key board, and the tail end of each pressing column is provided with a positioning block clamped into the positioning hole. The utility model discloses an elastic structure of a switch panel, which is characterized in that a circuit board and a bottom frame are sequentially arranged on the front surface of a bottom box, namely, one side facing a user, a key board is arranged on the front surface of the bottom frame, one key board can be arranged according to the requirement, a plurality of key boards can be arranged along the transverse direction or the vertical direction, the switch panel is divided into a plurality of areas by the key boards, the bottom frame and the circuit board are correspondingly divided into a plurality of areas, a touch switch is respectively arranged in the center of each area of the circuit board, T-shaped spring arms are arranged in the middle of the upper side and the lower side of each area or in the middle of the left side and the right side of each area, positioning holes are formed at the two ends of the T-shaped top of each spring arm, namely, each support rod is provided with a structure of two spring arms and four positioning holes, and a pressing column for respectively pressing each support rod is correspondingly arranged on the inner side of the key board, and a positioning block is clamped in the positioning hole. According to the switch panel structure, on one hand, the spring arm and the key board are relatively positioned through the positioning holes and the positioning blocks, a user cannot loosen when pressing the key board, so that the use experience is effectively improved, and on the other hand, the T-shaped spring arm is arranged in the middle of two sides of each area instead of at the corners, and can provide higher reset acting force for the key board, so that the working stability of the switch panel is improved. Preferably, the elastic arms are provided with elastic arm holes with the same shape as the elastic arms at the positions opposite to the elastic arms on the underframe, the elastic rods of the elastic arms extend out along the directions parallel to the outer side surfaces of the underframe, and the supporting rods are arranged on the outer side surfaces of the end parts of the elastic rods and protrude out of the elastic arm holes.
