Vibration switch
(1) technical field
The present invention relates to a kind of vibration switch, relate in particular to a kind of multidirectional many controlling signal vibration switch.
(2) background technology
See also shown in Figure 1ly, Fig. 1 is the cutaway view of existing vibration switch, comprises metal shell 1, bearing 2, spring 4, terminal 5 and bumps hammer 6.Describedly bump the end that hammer 6 is fixed on spring 4, when vibration switch is influenced by external force, bump hammer 6 and form a conducting loop with housing 1 touching.This vibration switch can only be done " conducting/disconnection " single signal output.When vibration switch was subjected to the external impacts of different sizes, direction, the strain of its spring may more also may be less, but the spring flexible also may bending rock, existing vibration switch can't produce corresponding signal and be distinguished to different external force.
(3) summary of the invention
The object of the present invention is to provide and a kind ofly produce multiple signal and distinguish the vibration switch of external force.Further purpose of the present invention is to provide the vibration switch that can distinguish external force size or direction.
For achieving the above object, the present invention is by the following technical solutions:
A kind of vibration switch, comprise a housing, one flexible member and a bearing, housing be conduction and be provided with leg and form the first terminal, housing comprises the room with opening, the bearing of insulation is located at the opening part of room, the flexible member of conduction is installed in the room, flexible member have one with the fixing stiff end and of bearing near the innermost movable end of room, be equipped with second terminal on the bearing, second terminal and flexible member stiff end are conductings, influenced by an external force and during strain at flexible member, the movable end of flexible member and housing are touched and are made the first terminal and second terminal form a conducting loop, it is characterized in that: the inner barrel that is provided with a conduction in the room, inner barrel have one with the fixing installation end and of bearing near the innermost guiding access of room, the installation end of inner barrel is provided with and passes the outwardly directed leg of bearing and form the 3rd terminal, the inner barrel sky is enclosed within outside the flexible member, be provided with the space between housing and the inner barrel, influenced by an external force and when crooked, the guiding access of flexible member and inner barrel is touched and made second terminal and the 3rd terminal form a conducting loop at flexible member.
Because inner barrel can form new conducting loop with flexible member, can send new control signal, thereby can distinguish external force.
Technique scheme can also be further improved by following technical measures.
For distinguishing the size of external force, can do following improvement:
The axial location of the guiding access of inner barrel is corresponding with the flexible member stage casing;
Flexible member influenced by an external force and bending and degree of crook hour, the guiding access of only have elastic component stage casing and inner barrel is touched and is made second terminal and the 3rd terminal form a conducting loop, and disconnects between the first terminal and second terminal;
Influenced by an external force and bending and degree of crook when big at flexible member, flexible member makes second terminal and the 3rd terminal form a conducting loop with the guiding access touching of flexible member stage casing and inner barrel earlier, touches and make the first terminal, second terminal, the 3rd terminal to form the while conducting with the movable end and the housing of flexible member again.
For distinguishing the direction of external force, can do following improvement:
The axial location of the guiding access of inner barrel is corresponding with the movable end of flexible member;
Influenced by an external force and when extending at flexible member, the movable end of flexible member is vertically with the housing touching and make the first terminal and second terminal form a conducting loop;
Influenced by an external force and when crooked, the movable end of flexible member is touched with the guiding access of inner barrel and made second terminal and the 3rd terminal form a conducting loop at flexible member.
The improvement of relevant flexible member is: flexible member is a spring, the movable end of spring than the diameter of other parts big and spring apart from little.Perhaps, flexible member comprises that a spring and bumps hammer, bumps hammer and comprises head and shank, and the shank that bumps hammer is filled in an end of spring and will be bumped hammer and be fixed on the spring, and the head that bumps hammer is touched housing or inner barrel as the movable end of flexible member.
Improvement partly has about bearing: bearing comprises annular wall and newel, newel is located at the bearing center, annular wall is around newel, annular wall is filled in the opening of housing, the installation end of inner barrel inserts the annular wall inner chamber and reclines or close annular wall, and the stiff end of flexible member is enclosed within on the newel and the newel that reclines.Perhaps, bearing comprises annular wall and center, and center is located at the bearing center, annular wall is around center, annular wall is filled in the opening of housing, and in the installation end insertion annular wall and the gap between the center of inner barrel, the stiff end of flexible member inserts in the center.
The present invention is simple and reasonable, and is easy to use, easy to manufacture, has simple recognition function, and when suffered external force difference, its controlling signal of sending is also different.The present invention has the size and the weight of external power that can discern the swing dynamics or gets excited power forward and send different signal output, can judge the preferable switch of light, Beijing South Maxpower Technology Co. Ltd's power of swing dynamics, thereby be widely used in the industries such as electronic product, electronic digital product, anti-theft product, electronic toy, electronic game machine.
