Abstract
The present utility model provides a rotary coding structure for a navigation switch. The structure comprises a turn button, a rotary shell body, a pedestal and a bottom plate, the rotary shell body is arranged on the pedestal, a certain gap is formed between the bottom part of the rotary shell body and the bottom plate; a plurality of gaps are uniformly arranged on the side wall of the bottom part of the rotary shell body, and a photoelectric encoder is arranged on the bottom plate; a transmitting end and a receiving end of the photoelectric encoder are respectively arranged inside and outside the rotary shell body, and the horizontal position of the transmitting end and the receiving end is higher than a bottom edge of the rotary shell body and lower than the bottom edge of the gap. In the rotary coding structure for the navigation switch, the turn button is rotated to drive the rotary shell body to rotate, the rotation angle of the turn button can be obtained by the photoelectric encoder through counting frequency of input or non-input of the receiving end, and through corresponding the rotary angle to multilevel menus, the navigation switch is provided with a plurality of rotary shifts, thus operation complexity of the navigation switch can be greatly simplified.
Description
Technical field
The utility model belongs to the auto parts and components field, is specifically related to a kind of rotary coding structure that is used for Navigational button.
Background technology
Built-in gps antenna can receive from 3 data messages that transmitted in earth-circling 24 gps satellites at least in the auto-navigation system; In conjunction with the electronic chart that is stored in the automatic navigator; The position coordinates of confirming through gps satellite signal is complementary therewith, confirms the accurate position of automobile in electronic chart.On the basis of location, auto-navigation system can also pass through multi-functional display device, and best traffic route is provided, information such as the place ahead road conditions and nearest gas station, restaurant, hotel.If unfortunate gps signal interrupts, therefore you get lost, and do not worry that also GPS has write down your traffic route, and you can also return by former road; Certainly, these functions all be unable to do without Navigational button.But present existing Navigational button generally all can only carry out the selection of four direction, and promptly map is being searched and selected to four direction up and down, when perhaps getting into multilevel menu, and the operation more complicated.
Summary of the invention
The utility model provides a kind of rotary coding structure that is used for Navigational button to the deficiency of above-mentioned prior art; This rotary coding structure is used for Navigational button, can makes Navigational button have a plurality of rotation gears, simplify the complicated operation degree of Navigational button.
The utility model is realized through following technical scheme: a kind of rotary coding structure that is used for Navigational button, it is characterized in that comprise knob, rotary shell, pedestal and base plate, said knob and rotary shell are connected together, and link with rotary shell; Said pedestal is fixedly connected with base plate, and rotary shell is arranged on the pedestal, between the bottom of rotary shell and the base plate certain interval is arranged; Evenly be provided with a plurality of breach on the side walls of said rotary shell, base plate is provided with a photoelectric encoder; The transmitting terminal of said photoelectric encoder and receiving terminal lay respectively at the inside and outside both sides of rotary shell, and the horizontal level of said transmitting terminal and receiving terminal is higher than the bottom sides edge of rotary shell, are lower than the bottom sides edge of said breach.
The further setting of the utility model is, is connected with the mode of buckling between said rotary shell and the pedestal.
The further setting of the utility model is that said photoelectric encoder is a penetration optical sensor.
The further setting of the utility model is that said breach is 6.
The described rotary coding structure that is used for Navigational button of the utility model, through turning knob, driven rotary housing rotation, when the transmitting terminal of photoelectric encoder and receiving terminal were rotated housing and block, the light that photoelectric encoder sends was interrupted, and receiving terminal does not have input; When the transmitting terminal of photoelectric encoder and receiving terminal were positioned at gap position just, the light that photoelectric encoder sends was not blocked, and receiving terminal has input; Photoelectric encoder has or does not have the number of times of input through the statistics receiving terminal; Can know the angle of knob; Through the anglec of rotation is corresponding with multilevel menu, then can make Navigational button have a plurality of rotation gears, thereby simplify the complicated operation degree of Navigational button greatly.

The implication of each label is following among the figure:
Pedestal-1, base plate-2, knob-10, rotary shell-11, breach-12, photoelectric encoder-13, transmitting terminal-14, receiving terminal-15.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Like Fig. 1, shown in 2, the utility model provides a kind of rotary coding structure that is used for Navigational button, comprises knob 10, rotary shell 11, pedestal 1 and base plate 2, and said knob 10 is connected together with rotary shell 11, with rotary shell 11 interlocks; Be connected through screw between said pedestal 1 and the base plate 2, rotary shell 11 is arranged on the pedestal 1, can freely rotate in order to make rotary shell 11, is connected with the mode of buckling between said rotary shell 11 and the pedestal 1.
Evenly be provided with a plurality of breach 12 on the side walls of said rotary shell 11, base plate 2 is provided with a photoelectric encoder 13; Between the bottom of rotary shell 11 and the base plate 2 certain interval is arranged, this gap mainly is to be used to allow photoelectric encoder 13 processes.Preferably, said breach is six, and so this rotary coding structure then has 6 (360/6) individual gears.Photoelectric encoder 13 described in the present embodiment is a TCPT1300X01 type penetration optical sensor, and it has two apertures (two detectors) of 0.3mm and the gap of 3.0mm.
The transmitting terminal 14 and the receiving terminal 15 of said photoelectric encoder 13 lays respectively at the inside and outside both sides of rotary shell 11; The horizontal level of said transmitting terminal 14 and receiving terminal 15 is higher than the bottom sides edge of rotary shell 11; Be lower than the bottom sides edge of said breach 12, so just can periodically transmitting terminal 14 and receiving terminal 15 be blocked.
The utility model not only is confined to above-mentioned embodiment; Persons skilled in the art are according to the disclosed content of the utility model; Can adopt other multiple embodiment to implement the utility model, therefore, project organization of every employing the utility model and thinking; Do some simple designs that change or change, all fall into the scope of the utility model protection.
