Referring to Fig. 1, the utility model provides a kind of Waterproof key structure 100 on electronic equipment, mainly solve The key water-proof structure design of electronic equipment is complicated and is unfavorable for the problem of installing.

In the embodiments of the present invention, Waterproof key structure 100 includes shell 10, the key with accommodating chamber 101 Ontology 20 and the elastic seal ring 30 being connected between shell 10 and keying body 20.It is offered on shell 10 and accommodating chamber 101 The key hole 102 of connection, keying body 20 include that both ends are pierced by the key column 201 of key hole 102 and from one end of key column 201 Button cap 202 that is extending to form and being located in accommodating chamber 101, the cross-sectional area of button cap 202 are greater than the cross of key column 201 Area of section and the side that will be far from key column 201 are resisted against on key trigger 40, and elastic seal ring 30 is set in key column On 201, and the both ends of elastic seal ring 30 are respectively arranged with the first adhesive layer 301 and the second adhesive layer 302, wherein the first bonding Layer 301 is non-dismountable bonding with button cap 202, and the second adhesive layer 302 and the inner wall of shell 10 are detachably be bonded, so that elasticity is close Seal 30 can follow the movement of key column 201 and be compressed or be stretched, i.e., by elastic seal ring 30 by shell 10 with press Key ontology 20 is tightly connected, to achieve the purpose that waterproof, structure is simple and facilitates manufacture and assembling, can be reduced and is produced into This.In the present embodiment, elastic seal ring 30 uses closed pore formula waterproof foam to be made to reduce cost, and key trigger 40 is Metal clips as switch to use, and the stroke of key column 201 is between 0.2-0.4mm, also that is, key column 201 can press To close to the mobile 0.2-0.4mm in the direction of accommodating chamber 101 under effect, then resetted under the elastic reaction of elastic seal ring 30, To realize the closure and disconnection of triggering key trigger 40.

Further, in one embodiment, the first adhesive layer 301 and the second adhesive layer 302 are double-sided adhesive, and first The viscosity of adhesive layer 301 is greater than the viscosity of the second adhesive layer 302, so that elastic seal ring 30 is equipped with the first adhesive layer 301 One end can be non-dismountable bonding with button cap 202, and elastic seal ring 30 be equipped with the second adhesive layer 302 one end then with shell 10 Inner wall be detachably bonded, on the one hand can reduce volume using double-sided adhesive, while double-sided adhesive price is lower and easy to use, can To reduce the set-up time, production efficiency is improved, on the other hand using the double-sided adhesive of two kinds of different viscosity, is facilitated keying body 20 Loaded and unloaded from shell 10 together with elastic seal ring 30, reduce replacement key time, reduction reprocess or safeguard at This.

Further, in one embodiment, clearance fit between elastic seal ring 30 and key column 201, facilitates key Column 201 is walked in elastic seal ring 30, be can reduce the resistance of Waterproof key structure 100 when in use, is also convenient for key sheet Body 20 resets under the elastic reaction of elastic seal ring 30.

Further, in one embodiment, key hole 102 is stepped close to one end of button cap 202 and is formed close Sealing groove 1021 and avoiding hollow groove 1022, and be interconnected between seal groove 1021, avoiding hollow groove 1022 and key hole 102, wherein sealing Slot 1021 is used to accommodate elastic seal ring 30 and shell 10 detachably be bonded one end, i.e. the bottom of seal groove 1021 and elasticity is close Detachably bonding, avoiding hollow groove 1022 can not for accommodating button cap 202 and elastic seal ring 30 for second adhesive layer 302 of seal 30 Dismantle one end of bonding.Herein it is noted that one end that elastic seal ring 30 is connected with button cap 202 need to be higher by avoiding hollow groove 1022 bottom is conducive to so that the bottom of avoiding hollow groove 1022 and button cap 202 are arranged close to the side interval of elastic seal ring 30 Button cap 202 follows key column 201 to move back and forth.In the present embodiment, seal groove 1021 and avoiding hollow groove 1022 can be with Shorten the length of keying body 20, to reduce the volume of Waterproof key structure 100, and then reduces the weight of electronic equipment.

In conclusion the utility model will by using the first adhesive layer 301 made of double-sided adhesive and the second adhesive layer 302 The both ends of elastic seal ring 30 are tightly connected with keying body 20 and shell 10 respectively, and structure is simple and facilitates manufacture and assembling, It can not only achieve the purpose that waterproof, while production cost is also effectively reduced.

The utility model is not only in the description and the implementation described, therefore for the personnel of familiar field For other advantage and modification is easily implemented, therefore without departing substantially from universal defined by claim and equivalency range Spirit and scope in the case where, the utility model is not limited to specific details, representative equipment and shown here as with retouch The diagram example stated.
