It is only used to explain the present invention, be not intended to limit the present invention.
Referring to Fig. 1, a kind of present invention preferably fingerprint press-key structure with balancing pole, including key upper housing 10, press
Key lower case 20 and balancing pole 30, the both ends of the balancing pole are connected to the upper housing, referring to fig. 2, the balancing pole
Middle part is provided with outer offset portion 40, and the balancing pole is connected by the outer offset portion with the key lower case, the key
Elastic mechanism 50 is provided between upper housing and key lower case.
Existing strip fingerprint key, the inside of fingerprint press-key structure is only provided with elastic mechanism, due to elastic mechanism
The center of fingerprint key is only occupied, the two sides of key are not stressed directly, and when pressing two sides, fingerprint key, which is easy to happen, to incline
Tiltedly lead to unbalance stress, one feel is bad pressing, and reduces the success rate of pressing, secondly push button longevity will shorten.
The present invention is in " several " font by joined balance bar structure, balancing pole in the structure of existing fingerprint key, is put down
The middle part of weighing apparatus bar deviates outward extends to form outer offset portion, in fingerprint key, two end structures of outer offset portion and balancing pole
At the motion structure of crank block, outer offset portion can be under force around the end rotational slide of balancing pole, outer offset portion
Presence make key upper housing that there is longer stress surface, the left and right sides is connected to one, when pressing fingerprint key two sides
When, key can be realized uniform stressed, greatly improve the feel of key, extend the service life of key.
Referring to Fig. 3, in preferred embodiment, the elastic mechanism in the present invention includes the metal elastic that the key upper housing is arranged in
Piece 60 and the column 70 for being used cooperatively with the metal clips that the key lower case is set.
Existing metal clips is mainly used on switch, and metal clips is applied to fingerprint press-key structure and worked as by the present invention
In, it is because structure has a recessed arc center, which has certain elasticity, when depressed, arc
Shape center is squeezed and deformed by external force, and key moves down and has upward elastic force, and after loosing one's grip, arc center restores to the original state, key
Bounce, existing metal clips can be realized by the arc center it is ultra-thin, also, the preferred metal clips select it is stainless
The round metal dome of steel material improves the uniformity of key feedback stress, stainless steel material is not oxidizable, cost using circle
Low, easy processing, thickness selects 0.05mm-0.1mm, the significant thickness for reducing whole fingerprint key.
In preferred technical solution, fingerprint recognition mould group, the metal clips setting are provided on the key upper housing

And the installation window of fingerprint recognition mould group is offered in the middle part of key upper housing, by fingerprint recognition equally by way of bonding
Mould group is adhered on key upper housing.
Further, referring to fig. 2, in the present embodiment, the front end of the key lower case is provided with for depressing described
The briquetting 80 of outer offset portion, the rear end of the key lower case, which extends internally, substrate 90, and the column 70 is mounted on the base
On plate, for fixing the outer offset portion with briquetting cooperation.Balancing pole is installed using specific mounting structure in the present invention
In key lower case, it is preferred that there are two briquetting settings therein, and column is provided with one, wherein the outer offset of balancing pole
Portion is folded in by the space of two briquettings and a column, two briquettings and a column form triangle, so that outer offset
Portion more has stability.
Referring to fig. 4, in preferred embodiments of the present invention, the left and right ends of the key upper housing are provided with for institute
State the mounting hole 100 of balancing pole connection, the opening 110 that the mounting hole is outward extended with convenient for balancing pole disassembly.Installation
Hole uses and the consistent circle in balancing pole section, and big compared with the diameter of balancing pole, preferred big 3mm, at this point, can to put down
Weighing apparatus bar can preferably slide, and will not because of mounting hole diameter it is excessive cause pressing when generate shaking, for convenience balance
The taking-up of bar, mounting hole are preferably outward extended with the opening compared with the balance small 3mm of shank diameter.
In preferred scheme, the left and right ends of the key lower case are provided with the ditch up and down for the balancing pole
Slot 120.The depth of the groove and the diameter of balancing pole are identical, guarantee that balancing pole has sufficient up and down space.
Further, the key upper housing in the present embodiment and key lower case are locked by bolt mechanism and snap device
Tightly, i.e., the left and right ends of the key upper housing are provided with bolt 130 and buckle 140, the corresponding position of the key lower case
It installs and is equipped with pin hole 150 and block tongue 160.Preferably, latch structure, In is arranged in the left and right sides in key upper-lower casing front end
Middle part at left and right sides of key upper-lower casing is provided with grapple structure, wherein latch structure can be realized between upper-lower casing
Precise positioning, grapple structure can guarantee to fasten between upper-lower casing close.
Preferably, the elastic mechanism is provided with 3 groups.3 groups of elastic mechanisms are set and respectively correspond the position of key left, center, right three
It sets, pressing feedback effects are more preferable, meanwhile, 3 groups of elastic mechanisms are mutually backups, and further verify the service life of fingerprint key.By
It needs to be connected by winding displacement with terminal mainboard in fingerprint recognition mould group, it is more compact for the ease of winding displacement and structure, referring to figure
2, the rear end of the key lower case is provided with the crossed beam trunking 170 for fingerprint mould group winding displacement.
In conclusion a kind of fingerprint press-key structure with balancing pole provided by the invention, including key upper housing, key
Lower case and balancing pole, the both ends of the balancing pole are connected to the upper housing, are provided in the middle part of the balancing pole outer inclined
Shifting portion, the balancing pole are connected by the outer offset portion with the key lower case, the key upper housing and key lower casing
Elastic mechanism is provided between body.The present invention has outer offset portion due to using between fingerprint key upper housing and lower case
