Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, and the most same or similar label represents same or similar element or has the element of same or like function.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.
Below with reference to Fig. 1-Fig. 8, the rotary encoder 100 according to this utility model embodiment is described.This rotary encoder 100 can be widely applied in various household electrical appliance, rotary encoder 100 rotary motion makes the loop signal that its internal generation is different, the controlling of household electrical appliance sends different action commands according to the different circuit signal that receives, thus the temperature of Effective Regulation household electrical appliance, pressure or rotating speed etc..
Rotary encoder 100 according to this utility model embodiment substantially may include that body 10, fluctuation dish 20 and brush 30.As depicted in figs. 1 and 2, body 10, fluctuation dish 20 and brush 30 can be the circular configuration that shape and structure cooperates.It is understood that body 10, fluctuation dish 20 and brush 30 can also be square or polygonized structure, do not describing in detail.
Specifically, body 10 is provided with installation portion 11, and the periphery of installation portion 11 is provided with along its circumferentially extending inner chamber conducting strip 12.Fluctuation dish 20 is located on installation portion 11 and rotatable around the axis of body 10, and brush 30 is located between body 10 and fluctuation dish 20 and with fluctuation dish 20 synchronous axial system, and brush 30 has at least two brush pawl 31, and brush pawl 31 only supports inner chamber conducting strip 12.It is to say, inner chamber conducting strip 12 is fixed on installation portion 11, brush 30 is located at the bottom of fluctuation dish 20 and can form loop by brush pawl 31 with inner chamber conducting strip 12 and be connected.The rotarily driving brush 30 synchronous rotary thus change brush pawl 31 and inner chamber conducting strip 12 link position of fluctuation dish 20.The change of brush pawl 31 and inner chamber conducting strip 12 link position makes to be formed between brush 30 and inner chamber conducting strip 12 different circuit signal.
Can be spaced in the circumference of inner chamber conducting strip 12 and at least two Jie electricity district and at least one Fei Jie electricity district are set, the rotation of fluctuation dish 20 brush 30 can be driven to rotate thus change brush pawl 31 and Jie electricity district and Fei Jie electricity district contact situation.When two brush pawls 31 coordinate with Jie electricity district simultaneously, constitute loop between brush 30 with inner chamber conducting strip 12 to be connected and form loop signal, and the controller of household electrical appliance is exported produced loop signal, controller sends corresponding action command signal after judging the loop signal received, thus realizes the switching to household electrical appliance difference in functionality.
Such as, when being controlled the switch on and off of household electrical appliance by rotary encoder, when inner chamber conducting strip 12 can be provided with Liang Gejie electricity district and a non-electrical district, one of them brush pawl 31 of brush 30 can coordinate with Jie electricity district all the time, is made another brush pawl 31 of brush 30 alternately contact with Jie electricity district and Fei Jie electricity district by rotation wave Moving plate 20.When another brush pawl 31 of brush 30 contacts with Jie electricity district, it is collectively forming loop signal between two brush pawl 31 and Liang Gejie electricity districts, now the controller of household electrical appliance will send the command signal of conducting switch, when another brush pawl 31 of brush 30 contacts with Fei Jie electricity district, not producing loop signal between brush 30 and inner chamber conducting strip 12, now the controller of household electrical appliance will send the command signal disconnecting switch.
It is understood that above-described embodiment is only illustrative, it is not to restriction of the present utility model.Inner chamber conducting strip 12 can set plural Jie electricity district and Fei Jie electricity district, correspondingly, plural brush pawl 31 can be provided with on brush 30, thus different loop signals can be produced at inner chamber conducting strip 12 from brush 30, the controller of household electrical appliance to sending different work orders, and then realizes switching to household electrical appliance difference in functionality according to different loop signals.
Brush 30 and inner chamber conducting strip 12 can be that the preferable metal material of electric conductivity is made, such as, copper sheet or silver strip, body 10 and fluctuation dish 20 can be that plastic ejection moulding forms, wherein, inner chamber conducting strip 12 can dissolve joining technique by ejection formation and is embedded in body 10 by inner chamber conducting strip 12.As depicted in figs. 1 and 2, body 10 and fluctuation dish 20 can be formed generally as cylinder, and inner chamber conducting strip 12 is partially exposed at the upper surface of body 10, so that the brush pawl 31 of brush 30 can contact with inner chamber conducting strip 12.Inner chamber conducting strip 12 is extended with terminal supportor 15 to body 10 bottom direction, and terminal supportor 15 is connected with the controller of household electrical appliance.
Rotary encoder 100 according to this utility model embodiment, changes the brush pawl 31 position relative to inner chamber conducting strip 12 of brush 30 by rotation wave Moving plate 20, such that it is able to form different loop signals between brush 30 from inner chamber conducting strip 12.This rotary encoder 100 simple in construction, processing and manufacturing low cost and easy to operate.
In embodiments more of the present utility model, rotary encoder 100 also includes: at least one Location resilient piece 40.Location resilient piece 40 is located on body 10 and is positioned at the periphery of inner chamber conducting strip 12, at least some of periphery wall only supporting fluctuation dish 20 of Location resilient piece 40.As shown in Figure 8, fluctuation dish 20 is located at the end face of body 10 and coordinates with installation portion 11, and the inner of Location resilient piece 40 is only against the periphery wall of fluctuation dish 20.So, when fluctuation dish 20 rotates.Location resilient piece 40 will play interference effect for the rotation of fluctuation dish 20.During additionally, fluctuation dish 20 and Location resilient piece 40 are touched, fluctuation dish 20 slips over Location resilient piece 40 can send the slight sound, and user can substantially experience fluctuation dish 20 turned position, thus increase user and position sense.
In a specific embodiment of the present utility model, as shown in Figure 1, Figure 2, shown in Fig. 5 and Fig. 8, the periphery wall of fluctuation dish 20 is provided with multiple positioning tooths 21 of circumferentially spaced layout, limits locating slot 22, stretching at least partially in locating slot 22 of Location resilient piece 40 between adjacent two positioning tooths 21.Body 10 is provided with the installation buckle 13 being suitable to install Location resilient piece 40, and the two ends of Location resilient piece 40 are separately mounted to install on buckle 13, and Location resilient piece 40 is provided with the positioning convex 41 being adapted to extend in locating slot 22.
