Example Embodiment

[0041] Implementation mode one

[0042] Such as Figure 3 to Figure 7 As shown, a multi-cantilever key includes a pressing portion 110 and a fixing portion 120, wherein the pressing portion 110 is fixed on the fixing portion 120 by two symmetrically distributed elastic cantilevers 130.

[0043] It should be noted that the symmetrical distribution of the two elastic cantilevers 130 is the most preferred solution. Of course, the two elastic cantilevers 130 can also be arranged in a similar symmetrical distribution according to actual needs. At the same time, the number of elastic cantilevers 130 is not limited to two. In order to enhance the structural strength of the key, the number of elastic cantilevers 130 can also be more than two. However, regardless of the number of elastic cantilevers 130, the elastic cantilevers 130 need to be symmetrical. The symmetrical distribution is now axisymmetrical distribution or center-symmetrical distribution with respect to the pressing portion ...

Example Embodiment

[0058] Implementation mode two

[0059] In this embodiment, such as 9, Picture 10 As shown, the present invention provides another structure of a multi-cantilever key. The pressing part 210 of the multi-cantilever key is elliptical, and the key post 212 of the pressing part 210 is arranged at the center of the pressing part 210. The two axisymmetrically distributed elastic cantilevers 230 are of linear structure, the fixing part 220 is a plate-shaped structure, and a plurality of pressing parts 210 are provided on the outside of the plate-shaped structure through the elastic cantilever 230, and one end of the elastic cantilever 230 is elliptical. The center of the waist of the pressing part 210 is connected, and the other end is connected to the fixing part 220.

[0060] It should be noted that, in this embodiment, except that the specific structure of the double cantilever is different from the first embodiment, the other structures and cooperation relationships are the same as t...

[0061] Implementation mode three

[0062] In this embodiment, such as Picture 11 As shown, the present invention provides yet another structural form of a multi-cantilever key. The pressing portion 310 of the multi-cantilever key has a rectangular structure, and the key column of the pressing portion 310 is arranged at the center of the pressing portion 310. Two symmetrically distributed elastic The cantilevers 330 are all linear structures, the fixing portion 320 is a plate-shaped structure, and the pressing portion 310 is arranged in the middle of the plate-shaped structure through an elastic cantilever 330. One end of one of the two elastic cantilevers 330 is fixed to the first end of one side of the pressing portion 310, the other end of the elastic cantilever 330 is fixed to the fixing portion 320, and one end of the other elastic cantilever 330 is fixed to the other of the pressing portion 310. On one side of the second end, the other end of the elastic cantilever 330 is f...

Abstract

The invention relates to the technical field of operation buttons, and in particular relates to a multi-cantilever button and a controller. The multi-cantilever button comprises a pressing part and a fixing part, wherein the pressing part is fixed to the fixing part through a plurality of symmetrically-distributed elastic cantilevers. The invention also provides a controller employing the multi-cantilever button. The multi-cantilever button and the controller have the advantages that two symmetrically-distributed elastic cantilevers are used for fixing the pressing part, the pressing part is in parallel contact with a contact surface of touch switches during being pressed, and the button can uniformly bear the force during pressing, thus greatly avoiding wearing and breaking, and as a result, the service life of the button can be prolonged, and the reliability in use can be improved.

Description

technical field [0001] The invention relates to the technical field of operation keys, in particular to a multi-cantilever key and a controller. Background technique [0002] Cabinet air conditioners, mobile air conditioners, window air conditioners, split air conditioners, and the body controller boxes of various household appliances generally have button structures. control. The materials used in the key structure include plastic, rubber, glass and other materials, and the realization principles of the key are also mechanical, capacitive, and resistive, each with its own advantages. However, plastic (ABS, etc.) mechanical buttons are still widely used in various household electrical appliances to realize the control of the whole machine through the contact between the button structure and the tact switch. [0003] The traditional plastic mechanical keys commonly used at present generally adopt a single cantilever structure, such as figure 1 , figure 2 As shown, a comm...
