Description

Waterproof key mechanism for electronic product

Technical Field

The utility model relates to a technical field of electronic product, in particular to waterproof button mechanism for electronic product.

Background

Many electronic products (especially low-cost products) on the market have waterproof and dustproof requirements, the waterproof design at the key position is relatively complex, and the requirements on process and assembly are relatively high. The existing machine waterproof and dustproof keys on the market are complex in design, difficult to assemble and manufacture and high in cost.

SUMMERY OF THE UTILITY MODEL

To the weak point that exists among the prior art, the utility model aims at providing a waterproof button mechanism for electronic product reaches waterproof dirt-proof requirement, increases machine life. In order to realize the above objects and other advantages in accordance with the present invention, there is provided a waterproof button mechanism for an electronic product, comprising:

the main board fixing support is clamped with a shell, a main board fixed on the shell is fixedly connected with a key piece and a supporting and pressing piece which is abutted against the key piece;

the shell is provided with a pressing area, the shell in the pressing area is provided with a pressing component, and one surface of the pressing component, which is close to the key piece, is integrally connected with a supporting pressing piece;

the pressing component is used for generating deformation so that the pressing component generates acting force to the key piece to enable the key piece to generate a pressing stroke.

Preferably, the thickness of the pressing member at a is 0.55 to 0.6MM, and the average thickness of the pressing member at B is 1 to 1.1 MM.

Preferably, the material of the housing is ABS.

Preferably, the area of the pressing region is not less than 20MM by 20 MM.

Preferably, the distance of the stroke of the key element is 0.3-0.5 MM.

Compared with the prior art, the utility model, its beneficial effect is: the invention achieves the purpose of plastic deformation for the keys which are not frequently used under the condition of sufficient structural space by reducing the thickness of the shell, and has no key hole on the appearance, thereby meeting the requirements of water resistance and dust resistance and prolonging the service life of the machine.

fig. 2 is a schematic diagram of a half-section structure of a pressing state of a waterproof key mechanism for an electronic product according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a waterproof key mechanism for an electronic product includes: a shell 2, a mainboard 3 fixed on the shell 2, and a key piece 4 and a supporting and pressing piece 5 which is abutted against the key piece 4 are fixedly connected to the mainboard 3; a pressing area is arranged on the shell 2, a pressing component is arranged on the shell 2 in the pressing area, and a supporting pressing piece 5 is integrally connected to one surface, close to the key piece 4, in the pressing component; the pressing component is used for generating deformation so that the pressing component generates acting force to the key piece 4 to enable the key piece 4 to generate a pressing stroke, the switch of the key piece 4 is triggered through plastic deformation when the pressing component is pressed, the purpose of pressing a key is achieved, and the appearance of the pressing component can be marked without a protrusion.

Further, the thickness of the pressing member at the position A is 0.55-0.6 MM, and the average thickness of the pressing member at the position B is 1-1.1 MM.

Further, the material of the housing 2 is ABS.

Further, the area of the pressing area is greater than or equal to 20MM by 20 MM.

Furthermore, the distance of the stroke of the key element 4 is 0.3-0.5 MM.

The number of devices and the scale of the processes described herein are intended to simplify the description of the present invention, and applications, modifications and variations of the present invention will be apparent to those skilled in the art.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application suitable for this invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and illustrations shown and described herein, without departing from the general concept defined by the claims and their equivalents.
