Problems solved by technology

The above structure has the following problems: the top surface of the key post is not parallel to the surface of the tact switch, and the axis line is not aligned after repeated use of the key; the diameter of the key post is too small to avoid jamming due to assembly deviation; Ensure that the key is in contact with the switch plane, and the force is uneven for a long time, and it is prone to breakage; the key failure rate is high, the reliability is poor, and there are quality risks

Embodiment approach 1

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

[0043] It should be noted that the above-mentioned 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 button, the number of elastic cantilevers 130 can also be more than two, but regardless of the number of elastic cantilevers 130, the elastic cantilevers 130 need to be symmetrical. The symmetrical distribution refers to the axis-symmetrical distribution or the center-symmetrical distribution with respect to the pressing part 110 .

Embodiment approach 2

[0059] In this embodiment, as 9, Figure 10 As shown, the present invention provides another structural form of the multi-cantilever key, the pressing part 210 of the multi-cantilever key is elliptical, and the key column 212 of the pressing part 210 is arranged at the center of the pressing part 210 . The elastic cantilevers 230 distributed symmetrically on both axes are all linear structures, the fixed part 220 is a plate-shaped structure, and a plurality of pressing parts 210 are arranged on the outside of the plate-shaped structure through the elastic cantilever 230, and one end of the elastic cantilever 230 is in an oval shape. The center of the waist of the pressing part 210 is connected, and the other end is connected with the fixing part 220 .

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

Embodiment approach 3

[0062] In this embodiment, if Figure 11 As shown, the present invention provides yet another structural form of the multi-cantilever button. The pressing part 310 of the multi-cantilever button is a rectangular structure, and the button column of the pressing part 310 is arranged at the center of the pressing part 310. Two symmetrically distributed elastic The cantilevers 330 are all linear structures, the fixing part 320 is a plate-shaped structure, and the pressing part 310 is arranged in the middle of the plate-shaped structure through the elastic cantilevers 330 . One end of one of the two elastic cantilever arms 330 is fixed on the first end of one side of the pressing part 310, the other end of the elastic cantilever arm 330 is fixed on the fixing part 320, and one end of the other elastic cantilever arm 330 is fixed on the other side of the pressing part 310. The second end on one side and the other end of the elastic cantilever 330 are fixed on the fixing part 320 , a...

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...
