Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

Embodiment:

As shown in Fig. 1 to Figure 18, key switch, key switch includes press section, contact portion, fixed part；Press section can be slided Dynamic is nested in fixed part；Contact portion includes deformation unit and base unit；Contact portion is mounted on contact portion, base unit It is mounted on fixed part；With the pushing of press section, variant part deformation is moved down to be contacted with base unit；

Deformation unit includes dynamic touch panel, spring 212 and attachment base 213；

Dynamic touch panel includes two pieces of deformed plates 2111, and two pieces of deformed plates 2111 are symmetrically fixed on attachment base 213, spring 212 one end is mounted on attachment base 213, and it is direct to be located at two pieces of deformed plates 2111；Attachment base 213 is mounted on press section；When When dynamic touch panel and base unit contact, the other end and base contacts of spring 212.

By the way that the power size one that two pieces of deformed plates 2111 can be made to be subject between two pieces of dynamic touch panels is arranged in spring 212 It causes, touch panel dynamic in this way will be more stable when contact with base unit, while the stress also one when the reset of dynamic touch panel It causes, it, will be more smoothly when top on press section in this way when dynamic touch panel resets.

Specifically, base unit includes two pieces of contact plates 221 corresponding with deformed plate 2111 respectively；Contact plate 221 is installed On fixed part.

By the way that the contact plate 221 that two pieces contact with deformed plate 2111 can be electrically connected by the attachment base 213 that two pieces connect.

Specifically, the outer profile that two pieces of deformed plates 2111 are formed is diamond shape；The inside of the free end of two pieces of deformed plates 2111 Surface is equipped with ball convex 21111；The lateral surface of two pieces of contact plates 221 is equipped with crowning 2211；When press section pushes, deformed plate 2111 ball convex 21111 is contacted with the crowning 2211 of contact plate 221.

The steady of deformation direction of the deformed plate 2111 during deformation can be guaranteed by setting diamond shape for deformed plate 2111 It is qualitative, so that the deforming degree that can be stable of deformed plate 2111 improves, the further service life for improving product.Pass through Ball convex 21111 can allow deformed plate 2111 smoothly with release plate outer side contacts.

Specifically, fixed part is equipped with the pilot hole 311 being oriented to spring 212 and struts two pieces of deformed plates 2111 are distracted Protrusion 312 after press section pushes, struts the interior side contacts with 213 fixed connecting end of attachment base of protrusion 312 with deformed plate 2111.

The deformation direction of spring 212 can be made solid by the way that the pilot hole 311 being oriented to spring 212 is arranged in fixed part It is fixed, so that the direction for the power that spring 212 generates is fixed, it can thus make the attachment base 213 connecting with spring 212 Impact direction is fixed, so that the resetting movement of press section is rectangular just fixed, when reset and pressing of last press section will be very It is smooth.

It can guarantee that deformed plate 2111 is integrally located at the two sides of contact chip after pressing by strutting protrusion 312, thus The steady contact position of deformed plate 2111 Yu contact chip may be implemented, to realize reliable connection effect.

Specifically, press section includes inner ring 11, centre circle 12 and outer ring 13；

The edge of inner ring 11 is equipped with stepped recesses 111；The lower surface of 12 inside of centre circle is equipped with and 11 stepped recesses 111 of inner ring Matched step protrusion 121；The upper surface of 12 inside of centre circle is equipped with and mounting groove 122；The inside edge of outer ring 13 is equipped with in Enclose the matched pressing groove 131 of 12 mounting groove 122；Outer ring 13 and fixed part are affixed.

By the design of inner ring 11, centre circle 12 and outer ring 13, product can be according to the demand pair of actual color and texture The production of 11 being customized of inner ring 11, centre circle 12 and inner ring.

Specifically, 11 lower surface of inner ring is equipped with guide post 112 and the elastic button hook 113 with guiding role；

Fixed part is equipped with the guide groove 313 of the surface matching of guide post 112, and fixed part is equipped with and matches with elastic button hook 113 Hook slot 314；The bottom for hooking slot 314 is equipped with and can keep off with the matched hook of the hook of elastic hook.

It is fixed by the direction that guide post 112 can make press section move when pressing, passes through elastic button hook 113 Can make can only do slide displacement between press section and fixed part is still not completely separated.

Specifically, fixed part includes set casing 31 and bottom plate 32；Bottom plate 32 is mounted on the bottom of bottom case, base unit It is mounted on bottom plate 32；Bottom case is equipped with the interface channel 315 of base unit and external connection.

Deformed plate 2111 can be protected and be settled out with the course of work contacted by set casing 31, pass through bottom Cover board 32 is separated with set casing 31, be can be convenient replacement and installation contact chip, is reduced assembly time, while can be by contact chip It is hidden, plays crimping and prevents the effect released by contact chip.

Specifically, bottom plate 32 and set casing 31 are connected by a snap.

It is connected by a snap the connection that can be convenient bottom plate 32, while the secure stability of connection.

Specifically, fixed part is equipped with positioning and prevents the convex closure 316 of itself rotation.

The convex closure 316 that setting prevents itself from rotating on fixed part can guarantee the stability after this product installation, also side Just it installs.

Specifically, fixed part is equipped with the flexible fastening buckle 317 that fixed part is fixedly mounted；Flexible fastening buckle 317 1 Hold, the top of other end direction fixed part affixed with fixed plate；The longitudinal section of the free end of flexible fastening buckle 317 is step Shape.

It can be convenient for this product to be installed in other equipment by flexible fastening buckle 317 and be fixed.

The utility model uses in this way, the both ends for the circuit being connected to will be needed to connect respectively with contact chip, then will connect Contact is mounted on bottom plate 32, then by 32 spiral-lock of bottom plate on set casing 31.

Attachment base 213 is mounted on inner ring 11, then inner ring 11 is withheld on set casing 31 downwards, the bullet on inner ring 11 Property button hook 113 is caught in the hook slot 314 on set casing 31.

It is thus installed this product, when press section presses down on, spring 212 is compressed, deformed plate 2111 separate under the action of strutting protrusion 312, by two pieces of deformed plates 2111 are opposite, last deformed plate 2111 on contact chip Crowning 2211 contact.

After unclamping press section, deformed plate 2111 is separated with contact plate 221.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, should all without departing from the objective and range of the technical program Cover in the scope of the claims of the utility model.
