The magnetic ring with the function of a magnetic field is arranged in the groove of the rotary wheel, and the magnetic ring and the depressed key are fixed on the printed circuit board in a combination way by the connecting piece on which the socket connectors for protecting the surface of the printed circuit board and positioning the height of the printed circuit board are arranged; two hall elements are correspondingly arranged on the printed circuit board; the magnetic ring produces a rotary magnetic field along with the rotation of the rotary wheel, and produces electromotive force with the hall elements arranged on the printed circuit board; the surface of the magnetic ring is attached with N different-polar magnetic field spaces; and with the continuous changes of the magnetic field spaces, the hall elements produce alternating electromotive force, and continuous output signals are produced by the printed circuit board. The control electric motor has simple structure and reliable performance, can rapidly output television navigation signals, is time-saving and labor-saving in operation, improves the search efficiency of the television, and reduces the time cost.
Description
Technical field
The utility model relates to a kind of television set Navigation Control motor, particularly a kind of television set Navigation Control motor of rotary-type structure.
Background technology
At present, the television set Navigation Control adopts the fixedly navigation keys of 4 arrows mostly, need rely on the location of button on the housing of TV set to choose the content at television set internal control interface during use, produce single movable signal by button with contacting of DOME (film key), this method wastes time and energy, and efficient is lower.Present a large amount of photo and the written historical materials of storage usually in the television set, if run into more content search could be very loaded down with trivial details; Therefore, in order to improve the search efficiency of television set, make it simple and efficient to handle, existing television set Navigation Control structure is improved, thereby the raising search capability reduces the operating time, makes its performance more reliable, to adapt to the demand in market, be one of new problem of the continuous research and development of this field scientific research technical staff.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and the television set Navigation Control motor of a kind of simple in structure, dependable performance, simple and efficient rotary-type structure is provided.
The technical scheme that the utility model adopted is for achieving the above object: a kind of television set Navigation Control motor of rotary-type structure is characterized in that comprising that the runner, magnet ring, button, printed substrate, Hall element, connector, the connector that have groove connect to form; Magnet ring with the action of a magnetic field places in the runner groove, and is fixed on the printed substrate by the connector combination with button, and connector is provided with the protection print circuit board surface and locatees the connector of its height; Described printed substrate is provided with Hall element, magnet ring in the runner produces the magnetic field of rotation along with the rotation of runner, the Hall element that is provided with printed circuit board (PCB) produces electromotive force, the magnetic field space of the surface attachment N of a magnet ring opposed polarity, continuous variation along with magnetic field space, Hall element produces the electromotive force of alternation, produces continuous output signal by printed substrate.
The beneficial effects of the utility model are: the utility model has added rotary-type rapid navigation mechanism on original control structure, this mechanism can produce continuous output signal by the changes of magnetic field of opposed polarity, on the basis of the single signal of original manual output, added the continuous signal output of quick search locomotivity.Its its specific structure design can be exported the television set navigation signal rapidly, thereby omits the loaded down with trivial details property of conventional television button navigation.The utility model assembling convenient fixing is quick, pattern novelty, simple to operate, dependable performance; Time saving and energy saving in the operation, as to improve television set search efficiency reduces time cost.

Among the figure: 1 runner, 2 magnet rings, 3 buttons, 4 printed substrates, 5 Hall elements, 6 connectors, 7 connectors.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
Shown in Fig. 1～3, a kind of television set Navigation Control motor of rotary-type structure is characterized in that comprising that the runner 1, magnet ring 2, button 3, printed substrate 4, Hall element 5, connector 6, the connector 7 that have groove connect to form; Magnet ring 2 with the action of a magnetic field places in runner 1 groove, and is fixed on the printed substrate 4 by connector 7 combinations with button 3, and connector 7 is provided with protection printed substrate 4 surfaces and locatees the connector 6 of its height; Correspondence is provided with two Hall elements 5 on the described printed substrate 4, Hall element 5 produces two signals under the rotation of the magnet ring after the magnetic state 2 be respectively hall signal A and hall signal B, phase difference between the back takes place in signal, and state output as shown in Figure 3 forms continuous output signal.
Distance between described printed substrate 4 and the magnet ring 2 is consistent, and for guaranteeing the accuracy of fixed position, requires the making precision higher; Magnet ring 2 number of magnetic poles be the even number of symmetry, the magnetic pole purpose is to export magnetic flux uniformly, guarantees the hall signal A of Hall element 5 outputs and the consistency of hall signal B.
During assembling; using straight cutting melting mode connects runner 1 button 3 usefulness connectors 7; directly melting and navigating in the printed substrate 4; be located at surface and its height of location of the connector 6 protection printed substrates 4 on the connector 7, the phase difference of highly determining output signal that melting that is melting groove in the printed substrate 4.
During application, with hand rotating wheel 1, the Hall element 5 that is provided with above by printed substrate 4, under rotating, magnet ring after the magnetic state 2 produces hall signal A and two signals of hall signal B, T1, T2, T3, T4... chronologically, phase difference between the back takes place in signal, forms continuous output signal television set is carried out Navigation Control.
Above-mentioned detailed description of the television set Navigation Control motor of rotary-type structure being carried out with reference to embodiment; be illustrative rather than determinate; therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection range of the present utility model.
