Technical field
The utility model relates to a kind of handheld device or mobile terminal, particularly relates to a kind of mobile phone rotation detecting.
Background technology
Along with the development of science and technology, intelligent terminal, particularly mobile phone more and more become the indispensable articles for daily use of people, and the part mobile phone is provided with rotating camera, and how rotating camera being rotated to detect becomes the engineer and develop the key of mobile phone.
at present, rotation detects in the automotive electronics application more, few in the portable terminal device application, and permissible accuracy is not high when general application, so, implementation is generally fairly simple, cost and conforming consideration in addition, the general spacing mode of structure that adopts, such as, when rotating part rotates to a fixing angle, structure is stretched out a reference column and is done location, with the mode conducted signal of location contact etc., the benefit of this mode is, saved input IC, reduced cost, the detection and location precision is higher, but form is dumb, and can only limit corresponding position, another kind of implementation, it is exactly mode more common in automotive electronics, adopt the HALL components and parts to add corresponding magnet structure, this mode, although with respect to front a kind of mode, detection method and restriction position all increase, but can not accurately detect, and due to the problems such as consistency of magnet, for the requirement of accurate detection, can not meet, can only accomplish the detection of certain limit.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of mobile phone rotation detecting is provided, and simple in structure, accuracy of detection is accurate.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of mobile phone rotation detecting, comprise the rotating shaft of housing, rotating camera parts and connection housing and rotating camera parts, be provided with the magnetic induction measurement module on described housing, be provided with magnet on described rotating camera parts, described magnetic induction measurement module is electrically connected to signal processing circuit.
Described magnetic induction measurement module and magnet setting are at grade.

Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, in order to technical characterictic of the present utility model and advantage are carried out more deep annotation.
As shown in Figure 1, 2, a kind of mobile phone rotation detecting, comprise the rotating shaft 3 of housing 1, rotating camera parts 2 and connection housing 1 and rotating camera parts 2, be provided with magnetic induction measurement module 4 on described housing 1, be provided with magnet 5 on described rotating camera parts 2, described magnetic induction measurement module 4 is electrically connected to signal processing circuit.
Described magnetic induction measurement module 4 arranges at grade with magnet 5.For example, as shown in Figure 1, magnetic induction measurement module 4 is oppositely arranged with magnet 5, and location positioning, be arranged on same level, and within the specific limits.With respect to Hall HALL switch, the detection mode of HALL switch is that the magnetic line of force must vertically pass the HALL chip and just can detect, and exports corresponding signal; And reluctance switch is the magnetic line of force of horizontal direction, and is for take horizontal direction as the rotary body that detects axis, high more a lot of than HALL transducer accuracy of detection and detection range.But magnetic induction measurement module 4 and magnet 5 with must be arranged on same level, and within the specific limits.Described magnetic induction measurement module 4 is comprised of reluctance switch.For example, in Fig. 1,2, magnetic induction measurement module 4 changes with magnet 5 relative positions, namely by rotation, changes position, but the magnetic field that produces is strong and weak different, and magnetic induction measurement module 4 is by detecting the current rotating camera parts of the strong and weak judgement in the magnetic field 2 residing positions of rotation.
Described magnet 5 is comprised of magnet.Described signal processing circuit is arranged on the mobile phone master chip.Be provided with camera 6 and receiver 7 on described rotating camera parts 2.
Operation principle of the present utility model is as follows, mainly is divided into several aspects: magnet 5 forms magnetic field between this magnet 5 and magnetic induction measurement module 4; Magnetic induction measurement module 4, be positioned at magnet near, decide distance by the power in magnetic field and the size of magnet, detect the changes of magnetic field that the rotation due to rotating camera parts 2 produces; And signal processing circuit, for the treatment of the signal from magnetic induction measurement module 4, described signal processing circuit is arranged on the mobile phone master chip.
The utility model is arranging magnetic induction measurement module 4(reluctance switch) with magnet 5(magnet) relative position the time, first magnet is arranged on rotational structure, according to the corresponding topology layout of power adjustment of distance and the magnet magnetic of magnet and magnetic induction measurement module 4 positions; Then rotate corresponding rotational structure, and, according to the output situation adjustment distance between the two of detection signal, perhaps change the package size of corresponding magnet, perhaps model, debug the effect that reaches final repeatedly.
By the technical scheme in above embodiment, the utility model is carried out clear, complete description, obvious described embodiment is the embodiment of the utility model part, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment that obtains, and all belong to the scope of the utility model protection.
