Description
Technical field
The present invention relates to idler wheel technical fields, more particularly, to a kind of idler wheel detection structure.
Background technique
Idler wheel is because its moulding is changeable, and the characteristics of multi-gear adjustable, it is consumer to become automobile electronics and toy, mouse etc.
The common adjusting control module of product.
There are two types of the common detection modes of idler wheel: photoelectric detection switch detection and the detection of patch Hall switch, above two
In detection mode, photoelectric detection switch detection between by detected member distance limited, beyond cannot then be detected after certain range
Or detection accuracy reduces；Distance could must also trigger in a certain range between Hall switch and magnet.When idler wheel periphery have by
When the structures such as key, knob, roller axis is restricted at a distance from PCB, photoelectric detection switch detection and the inspection of patch Hall switch
Survey is not able to satisfy testing requirements or detection accuracy and reduces.
Therefore there are idler wheel detection mode and detection accuracy by the shadow of idler wheel periphery other structures for the existing detection mode of idler wheel
Ring larger technical problem.
Summary of the invention
Goal of the invention of the invention is to provide a kind of idler wheel detection structure, be solved using technical solution provided by the invention
Adjust what the idler wheel of control module was affected by idler wheel periphery other structures there are detection accuracy in existing electronic device
Technical problem.
In order to solve the above technical problem, the present invention provides a kind of idler wheel detection structure, including pcb board, be fixed on it is described
Bracket on pcb board and the idler wheel being arranged on the bracket；It further include contact pin Hall switch and magnet；The magnet is in circle
Ring-type, and be placed in the shaft of the idler wheel；The positive camber of the contact pin Hall switch and the magnet is solid in clearance fit
Due on the bracket, contact pin and the PCB plate are electrically connected.
Preferably, the distance between the contact pin Hall switch and magnet are not more than 3mm.
From the foregoing, it will be observed that using provided by the invention available following the utility model has the advantages that the present invention is opened Hall by contact pin
It closes and is electrically connected with pcb board, Hall switch and magnet are ensured by control Hall switch contact pin length and plastic rubber bracket height
The distance between, idler wheel drives magnet rotors when rotating, to trigger.The detection accuracy of this detection mode is higher, spatial adaptation
Property is strong；Idler wheel suitable for different height detects；Magnet size and weight can be reduced, reduce cost.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, the present invention will be implemented below
Attached drawing needed in the description of example or the prior art is briefly described.It should be evident that the accompanying drawings in the following description
Only a part of the embodiments of the present invention, for those of ordinary skill in the art, in not making the creative labor property
Under the premise of, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is idler wheel of embodiment of the present invention detection structure schematic diagram.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to solve the above-mentioned technical problem, the present embodiment provides a kind of idler wheel detection structures.Illustrating the embodiment of the present invention
Before, detection technique present in existing idler wheel is introduced, first to help to understand the relevant programme in the embodiment of the present invention.
There are two types of the common detection modes of idler wheel: photoelectric detection switch detection and the detection of patch Hall switch.Photoelectric Detection
Switch in detection mode, by with the limitation of the distance between detected member, after certain range, then cannot detect or detect essence
Degree reduces；In patch Hall switch detection mode, distance could must also trigger in a certain range between Hall switch and magnet.
When there are the structures such as key, knob on idler wheel periphery, roller axis is restricted at a distance from PCB, photoelectric detection switch detection and
The detection of patch Hall switch is not able to satisfy testing requirements or detection accuracy and reduces.
Referring to Figure 1, for this purpose, the present embodiment provides a kind of idler wheel detection structure, including pcb board 10, it is fixed on pcb board 10
On bracket 20 and the idler wheel 30 that is set on bracket 20, wherein idler wheel 30 can be rotated relative to bracket 20.
In order to solve in existing electronic device adjust control module idler wheel there are detection accuracy by idler wheel periphery other knot
The technical issues of being affected of structure, idler wheel detection structure provided in an embodiment of the present invention further include contact pin Hall switch 40 and magnetic
Iron 50.
Wherein magnet 50 is annular in shape, and is placed in the shaft of idler wheel 30；Contact pin Hall switch 40 is outer with magnet 50
Curved surface is fixed on bracket 20 in clearance fit, and contact pin and pcb board 10 are electrically connected.Contact pin Hall switch 40 and magnet 50 it
Between distance be not more than 3mm.
Hall switch and pcb board are electrically connected by the present invention by contact pin, pass through control Hall switch contact pin length and modeling
Glue support height ensures the distance between Hall switch and magnet no more than 3mm, and idler wheel drives magnet rotors when rotating, thus
Triggering.The detection accuracy of this detection mode is higher, and space adaptability is strong；Idler wheel suitable for different height detects；Magnetic can be reduced
Iron size and weight, reduce cost.
Embodiments described above does not constitute the restriction to the technical solution protection scope.It is any in above-mentioned implementation
Made modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution within the spirit and principle of mode
Within enclosing.
