Abstract
The utility model is related to spring mechanical field more particularly to a kind of three-in-one fingertip spring structures.Comprising foundation structure, touch spring is installed thereon, groove is included below the material section for touching spring, can be agreed with comprising protrusion, groove and protrusion above material section, it in itself will not be curved so that touching spring.Advantageous effect：Since groove and protrusion can agree with, when pressure from top to bottom, just there is certain guiding role at raised edge, and spring will not be bent.
Description
Technical field
The utility model is related to spring mechanical field more particularly to a kind of three-in-one fingertip spring structures.
Background technology
It touches spring and refers to that being exclusively used in condenser type and microcontroller touches the special purpose spring button of electric appliance.Spring is touched to be also known as
Touch sensible spring, by key spring, contact spring.
Utilizing spring structure capacitance inductor electricity -- the sensing of appearance formula is a kind of steady for conventional mechanical switch
Alternative solution.But, some applications cannot directly dispose printed circuit board under the cover, can not connect printed circuit board
It is connected on device housings.This kind of application includes household electrical appliance and radio, the TVs such as cooking stove, washing machine, refrigerator, micro-wave oven
The various vehicle electronics such as tuner, control panel, occupant detecting system on seat.
Metal spring inductor-can be substituted for solid-state conductance type inductor, in this way, the position of PCB separate can be covered
Cap rock, and reliable inductor connection can be provided under or temperature operating condition jumpy strong in vibrations.In addition, spring is also
It can provide backlighting for, merge and mechanically and electrically hold other functions such as button.
Existing touch spring has two be susceptible to after pressing is more the problem of：1. spring failure, fatigue or fracture；
2. spring is twisted, trigger action is not realized.《GW4 switch touching thrums spring replaces the design of tool》；Guo Yan;Jia Lin;
Zhang Wei is published in《Electrician is electrical》；The document of 2017-04-15 illustrates that fingertip spring belongs to the prior art.
Utility model content
The purpose of utility model：In order to provide a kind of effect, preferably three-in-one fingertip spring structure, specific purposes are shown in tool
Multiple substantial technological effects of body implementation section.
In order to reach as above purpose, the utility model adopts the following technical scheme that：
A kind of three-in-one fingertip spring structure, which is characterized in that comprising foundation structure, be equipped with touch spring, institute thereon
It states and includes protrusion comprising groove, material section top below the material section for touching spring, groove and protrusion can agree with, and then
It in itself will not be curved so that touching spring.
The further technical solution of the utility model is that the touch spring avris welds an avris plate, and avris plate connects
It is connected on the material edge of spring, also includes the lower switch being located on infrastructure, avris plate moves can trigger down downward
Fang Kaiguan.
The further technical solution of the utility model is that the avris plate is isolation material, which is plastics, should
Plastic heat sealing is on the edge of spring materials.
The further technical solution of the utility model is that the lower switch is travel switch.
Using the utility model of as above technical solution, had the advantages that relative to the prior art：Due to groove and
Protrusion can agree with, and when pressure from top to bottom, just there is certain guiding role at raised edge, and spring will not be bent.
Description of the drawings
In order to further illustrate the utility model, it is further illustrated below in conjunction with the accompanying drawings：
Fig. 1 is this patent utility model structure diagram；
Fig. 2 is the material section partial schematic diagram of spring body；
Wherein：1. foundation structure；2. touch spring；3. avris plate；4. lower switch.
This attached drawing is the schematic diagram of present apparatus critical piece composition, does not represent the appearance and size, connection side of the utility model
Formula, assembling form, position relationship etc., it is illustrated that section components are omitted.
Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.It should be noted that make in being described below
Word "front", "rear", "left", "right", "up" and "down" refer to the direction in attached drawing, and word " interior " and " outer " respectively refer to
Be directed towards or the direction far from particular elements geometric centers.
A kind of three-in-one fingertip spring structure, which is characterized in that comprising foundation structure, be equipped with touch spring, institute thereon
It states and includes protrusion comprising groove, material section top below the material section for touching spring, groove and protrusion can agree with, and then
It in itself will not be curved so that touching spring.The technique effect and its realization process for the essence that the technical solution at this place is played is such as
Under：Since groove and protrusion can agree with, when pressure from top to bottom, just there is certain guiding role at raised edge, allows bullet
Spring will not be bent.
The touch spring avris welds an avris plate, and avris plate is connected on the material edge of spring, also comprising position
In the lower switch on infrastructure, avris plate moves downward can trigger lower switch.What the technical solution at this place was played
The technique effect and its realization process of essence are as follows：It is triggered using the principle of dual trigger, it can than original touch spring
By property higher.
The avris plate is isolation material, which is plastics, and the plastic heat sealing is on the edge of spring materials.Institute
Lower switch is stated as travel switch.
In a creative way, each effect is individually present more than, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technique effect that more than structure is realized is realized, discounting for additional technical solution, this patent title is also
It can be a kind of spring.It is not shown in figure part details.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.Ability
The technical staff in domain should be recognized that the present utility model is not limited to the above embodiments, described in the above embodiment and specification
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen in claimed range.
