Description

One-piece notebook keyboard

Technical field

The present invention relates to the field of notebook keyboard technology, and in particular to a connected notebook keyboard.

Background technique

With the development of the information industry, notebook computers have been widely used. Especially in today's market, the demand for lightweight, ultra-thin, compact, low-cost notebooks is increasing, which puts higher requirements on the structural design and production assembly process of notebook keyboards and notebooks. However, the keyboard structure of the existing notebook computer is mostly composed of a combination of a button cap, a scissor foot, a printed circuit film and a metal base plate from top to bottom. The metal base plate is a plurality of metal base plates with a hook structure formed by punching a metal foil through a punch press. The cost and precision of the mold for manufacturing and processing such a metal base plate are extremely high, especially when the mold is stamped with a metal plate, the wear is easy to cause the accuracy of the product to be insufficient and the amount of waste is large, which causes serious loss of control and cost. More importantly, in order to achieve ultra-thin, the thickness of the metal plate is only 0.2mm, which is close to the edge of the blade. This makes it easy for the claw of the scissor foot to break during operation. In view of this, how to improve the structure of the notebook keyboard, Reducing production costs and meeting market demand are issues that need to be resolved.

technical problem

The object of the present invention is to develop a metal-free bottom plate according to the deficiencies of the prior art, and combine the hook on the metal base plate with the notebook base as a whole, simplifying the product structure, the production assembly process, and reducing the production cost. A notebook keyboard that meets the market's need for ultra-thin, lightweight, and precision notebooks.

Technical solution

In order to achieve the above object, the technical solution of the present invention is: a connected notebook keyboard, comprising: a plurality of spaced-apart button caps, a plurality of scissor legs corresponding to the button caps, and a plurality of elastic silicone bodies, a plurality of lower pin fixing seats corresponding to the lower pins of the plurality of scissor feet, a printed circuit film, the bottom surface of the button cap is provided with an upper pin fixing seat of the scissor foot, and the upper pin of the scissor foot is fixedly fixed on the assembled The lower pin of the scissor foot is inserted and fixed on the fixing seat of the lower pin, and the lower pin fixing seat and the notebook base are the same plastic integrally molded by the same plastic material in the same mold. The unitary piece, or the respective lower pin holders and the notebook base, are the same metal monolith that is die-cast from the same metal material in the same mold. The printed circuit film is flatly bonded to the notebook base through the lower pin holder, and the bottom of the elastic silicone body is fixed on the switch of the printed circuit film.

The fixing seat connecting the scissor feet may be a concave card slot type, or a hook type or a chute type.

The fixing seat connecting the scissors feet has at least two different fixing seats distributed on the base of the notebook and the bottom surface of the button cap to form a symmetry, which can make the scissors feet move up and down.

The printed circuit film may be directly bonded to the notebook base or may be fixed to the notebook base by grid pressing.

The scissor foot structure may be a symmetrical scissor foot and an asymmetrical scissor foot.

The notebook base is provided with a plurality of concave cylinders corresponding to the switch points of the printed circuit film.

Beneficial effect

After adopting the above structure, the invention cancels the traditional metal base plate on one hand, and integrally forms the hook structure and the notebook base on the metal base plate on the notebook base through the mold, and becomes the same material as the notebook base. The product structure and production assembly process are greatly simplified, the production cost is reduced, and the product is ultra-thin and ultra-light. At the same time, the lower pins of the scissor feet are more rigid and durable. On the other hand, the printed circuit film is bonded to the notebook base through the fixing base. Since the notebook base is more sturdy, the membrane switch is more flat, ensuring the accuracy of the circuit when it is closed.

Embodiments of the invention

As shown in FIG. 1-2, a connected notebook keyboard of the present invention includes a plurality of spaced-apart button caps 10, a plurality of scissor legs 20 corresponding to the button caps 10, and a plurality of elastic silicone bodies 40. a plurality of lower pin fixing bases 51 corresponding to the lower pins 21 of the plurality of scissor feet, a printed circuit film 30, the upper surface of the button cap 10 is provided with an upper pin fixing seat 11 of the scissor foot, and the upper part of the scissor foot is assembled The pin 22 is fixedly fastened to the upper pin fixing base 11, and the lower pin 21 of the scissor foot is fixedly fixed to the lower pin fixing base 51. The lower pin fixing base 51 and the notebook base 50 are made of the same plastic material. The same plastic integral piece integrally molded in the same mold, or the respective lower pin fixing base 51 and the base 50 of the notebook are the same metal integral piece integrally molded by the same metal material in the same mold. The printed circuit film 30 is flatly bonded to the notebook base 50 through the lower pin holder 51, and the bottom of the elastic silicone body 40 is fixed to the switch of the printed circuit film 30.

The fixing bases 11 and 51 connecting the scissor feet may be a concave card slot type or a hook type or a chute type.

The fixing bases 11 and 51 connected to the scissor feet have at least two different fixing seats 51 or 11 respectively distributed on the base 50 of the notebook and the bottom surface of the button cap 10, forming symmetry and allowing the scissors feet to move up and down. Structure.

The printed circuit film 30 may be directly bonded to the notebook base 50 or may be press-fitted to the notebook base 50 by a grid frame.

The scissor foot structure may be a symmetrical structural scissor foot 20 or an asymmetric structural scissor foot 20.

The notebook base 50 is provided with a plurality of concave cylinders 52 corresponding to the switching points of the printed circuit film 30.
