New Description: [New Technology Field] This creation is about a button structure, especially a thin button structure. [Prior Art] Since the push-button panel input method is simple in operation and high in accuracy for thin electronic devices, and its volume design is more in line with the demand for thinning of portable electronic products, it becomes a control operation for various electronic products. At present, in the development of the push-button panel, in addition to the trend toward thinner, the pursuit of the visual and tactile refinement to meet the needs of users. For the design of the thin button panel, the conventional structure adopts a hard button to press the metal shrapnel at the bottom, but the structural design is not only easy to cause the bottom of the panel button and the metal shrapnel to wear, but also the metal shrapnel is hard. The material will make the user feel uncomfortable with repeated touches and pursue the delicate needs.佼 刼 刼 面板 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构 结构_ degrees, and the creation of a larger force (four) must be programmed to touch the bottom circuit when the = button: =:: Asia makes the Qingcai relative also derived the lack of operational sensitivity M311078 poor. Although another conventional technique provides a method of molding the thin button by molding, the method is to form a film layer by hot pressing or injection molding, and the same is disposed under the button module printed with characters or images. The design of the thin-type button structure film layer can make up for the lack of the above-mentioned sensitivity, and the same, and it is more suitable for the thinning guide and needs. However, the structure of the film layer is too thin, so during the assembly process or the user is pressing. , § Xuanzang film stretch deformation deformation is insufficient, easy to break, making the thin button structure yield is low, which becomes the design flaw. [New content] Flying for the above-mentioned lack, the main purpose of this creation is to provide a thin key panel structure composed of a composite material, which can be used not only by a button layer but also with a brother-five flat layer. To achieve the requirement of thinning, the integrity of the structure of the button panel can be maintained when the user applies the external force to press the button panel structure. ► In order to achieve the above objectives, the present invention provides a thin key panel structure, the main structure of which comprises a button layer and a first elastic layer, wherein the button layer is injection molded with a plastic material having hardness, and the end face is Forming a plurality of recessed spaces, and partitioning them by a support portion at a central position, and further providing a button module on the upper end surface of the button layer, and the plurality of images are provided in the button module, and the plurality of recesses are provided The slotted area is separated by a plurality of pressing keys; and the Hierarch elastic layer is disposed under the button layer, and is integrally molded into the recessed space by a soft plastic material and attached to the button layer f and extends downwardly to the plurality of contact ends. At the same time, corresponding to the pressing button on the button layer, the 6 M311078 thin panel button structure is formed. [Embodiment j

Ester (PC), propylene bromide _ butyl styrene _ styrene (abs) 'ethylene (PE) and the like, and in this embodiment is a rigid thermoplastic polyacetate elastomer (TPE), and the button layer After the injection molding, a recessed space 1丨 is formed under A and two adjacent recessed spaces are separated and separated by a support portion 12. Please refer to the third figure, which is a partial enlarged view of the part (A) in the second figure, wherein the first elastic layer 2 is made of a flexible plastic material having a light transmissive property: a body is formed and formed in the recessed space of the button layer 1. _, the soft plastic material may be a soft thermoplastic polyester elastomer (TPE), silicone or rubber, and in this embodiment, a soft thermoplastic polyester elastomer (T?EJ is used, and along the recessed space 11 The button layers are attached to each other, and the first elastic layer 2 is further extended downwardly to form a contact end 21; finally, a light-emitting layer 3 is disposed under the contact end 21, and the light-emitting layer 3 can emit two poles. And in the embodiment, if the luminescent layer 3 is a luminescent plate, the contact end Η and the luminescent layer 3 abut each other; finally, under the luminescent layer 3, a second elastic layer 4 ′ is further disposed in this embodiment. It is a kind of metal shrapnel. In addition, a button module 13 M311078 is formed on the upper end surface of the button layer 1, and the key module 13 is provided with a plurality of images 5, as shown in the first figure. In the case of a shell, it is a numeric keypad. The image is 5 through printing technology, spraying or laser. The engraving or the like is formed in any manner; and the plurality of grooves 14a and 14b' are respectively disposed on the periphery of each image 5 on the button module 13 in the vertical direction and the parallel direction, and one of the grooves 14b is disposed on the support portion 12 The upper and lower parallel grooves 14a and 14b are connected to each other (or not connected to each other), and the positions of the images 5 are divided into a plurality of pressing keys 131, and each pressing button _ is corresponding to one The contact end 21 is a schematic diagram of the operation of the present invention. It can be seen that when the user presses the button 131 on the button 131, the user presses the button 131. The recessed grooves 14a and 14b and the recessed space 11 below the button layer 1 cooperate with each other, so that the button layer 1^ to which the pressing button 131 belongs has an elastic function, and is deformed downward while the user applies a force, The first elastic layer 2 that is in contact with the yoke is also deformed downward, so that the contact end 21 on the first elastic layer 2 and the second luminescent layer 3 on the luminescent layer 3 and the luminescent layer 3 are And causing the second elastic layer 4 to produce an acoustic sound, so that the user can feel the deer's massage effect, and when the user When the amount of pressure disappears, the elastic effect generated by the button layer ^ restores the button layer i and the first elastic layer 2 together.
