手机按键 技术领域  Mobile phone button
本实用新型涉及一种手机按键， 尤其涉及薄型手机的手机按键， 属于手机 按键的结构设计技术。  The utility model relates to a mobile phone key, in particular to a mobile phone key of a thin mobile phone, belonging to a structural design technology of a mobile phone key.
背景技术 Background technique
薄型手机是一种整体厚度非常薄的手机机型。 这种机型的手机在设计时 要求手机上的各个零部件的高度都达到最小化， 以达到减小手机整体厚度的 目的。 其中， 手机按键的厚度是影响手机的整体厚度的主要因素之一， 为了 满足手机薄型化的要求， 现技术中出现了一些超薄按键， 主要有两类： 。 金 属薄片型按键和聚酯薄片型按键。  The thin phone is a very thin mobile phone model. This type of mobile phone is designed to minimize the height of each component on the phone to reduce the overall thickness of the phone. Among them, the thickness of the mobile phone button is one of the main factors affecting the overall thickness of the mobile phone. In order to meet the requirements of thinning the mobile phone, some ultra-thin buttons have appeared in the prior art, and there are mainly two types: Metal sheet type buttons and polyester sheet type buttons.
金属薄片型按键是釆用金属薄片材料， 在金属片表面镂空并附着软性材 料以支持较好的手感。 缺陷在于： 原材料成本高， 工艺复杂， 生产难度大， 价格高； 而且字符键没有凸出， 外观效果单一， 金属弹性范围有限， 触摸手 感差。  The foil-type button is made of a metal foil material, which is hollowed out on the surface of the metal sheet and adheres to a soft material to support a good hand. The defects are: high raw material cost, complicated process, difficult production and high price; and the character keys are not convex, the appearance effect is single, the metal elasticity range is limited, and the touch feeling is poor.
聚酯薄片型按键与金属薄片按键结构相似 , 只是由聚酯薄片材料代替了 金属薄片材料。 缺陷在于： 聚酯薄片的厚度要求在 0. 4匪以上， 从而使整体按 键厚度超过了 1匪， 不利于进一步减小手机整体厚度； 并且字符键没有凸出， 触摸手感差， 外观造型简单。 实用新型内容 本实用新型要解决的问题是： 提供一种厚度很薄且制造工艺简单、 成本低 的薄型手机按键。 The polyester foil type button is similar in structure to the foil button, except that the foil material is replaced by a polyester foil material. The defect is: the thickness of the polyester sheet is required to be above 0.4 匪, so that the thickness of the overall button exceeds 1 匪, which is not conducive to further reducing the overall thickness of the mobile phone; and the character keys are not convex, the touch feeling is poor, and the appearance is simple. Utility model content The problem to be solved by the utility model is to provide a thin mobile phone button with a thin thickness, a simple manufacturing process and a low cost.
为了解决上述问题， 本实用新型的一个实施例是提供了一种手机按键， 其 中包括： 一层聚碳酸脂薄膜， 在所述聚碳酸脂薄膜表面具有通过二次注塑而 形成的字符键； 所述聚碳酸脂薄膜的背面与手机导电膜弹性接触。  In order to solve the above problems, an embodiment of the present invention provides a mobile phone button, comprising: a layer of polycarbonate film having a character key formed by overmolding on the surface of the polycarbonate film; The back side of the polycarbonate film is in elastic contact with the conductive film of the mobile phone.
通过本实用新型， 由于手机按键上的字符键是通过二次注塑而形成的， 因 此大大降低了手机按键的厚度； 并且制造工艺简单、 成本低； 另外， 二次注 塑的字符键还具有凹凸的立体效果， 使其更加美观。  Through the utility model, since the character key on the button of the mobile phone is formed by double injection molding, the thickness of the button of the mobile phone is greatly reduced; and the manufacturing process is simple and the cost is low; in addition, the character key of the overmolding also has concave and convex The three-dimensional effect makes it more beautiful.
下面通过附图和实施例， 对本实用新型的技术方案做进一步的详细描述。 附图说明  The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments. DRAWINGS

实施例 1 Example 1
本实施例提供了一种薄型手机的手机按键， 如图 1、 2所示， 包括： 一层 聚脂薄膜，具体地，该聚脂薄膜可以为聚碳酸脂（Po lyca rbona te , 简称： PC) 薄膜 1 , 在 PC薄膜 1表面具有通过二次注塑而形成的字符键 11，该字符键 包括 0-9的数字键及 "*" "#" 等控制键。 其中， PC薄膜 1的厚度为 0. 25mm; 字符键的厚度为 0. 15mm。 具体地， 字符键可以通过二次注塑 PC透明料而形成。 PC薄膜 1的背面与手机导电 膜（简称： DOME膜） 3弹性接触， 通过手机导电膜传导到手机内部的控制电 路中， 以实现手机按键的功能。 The embodiment provides a mobile phone button of a thin mobile phone, as shown in FIG. 1 and FIG. 2, comprising: a layer of polyester film. Specifically, the polyester film may be polycarbonate (Po lyca rbona te , referred to as PC). The film 1 has a character key 11 formed by overmolding on the surface of the PC film 1, and the character key includes a numeric key of 0-9 and a control key such as "*""#". 5毫米。 The thickness of the character key is 0. 15mm. Specifically, the character key can be formed by overmolding a PC transparent material. The back surface of the PC film 1 is elastically contacted with the conductive film of the mobile phone (abbreviation: DOME film) 3, and is transmitted to the control circuit inside the mobile phone through the conductive film of the mobile phone to realize the function of the button of the mobile phone.
本实施例所述手机按键上的字符键是通过二次注塑而形成的， 因此大 大降低了手机按键的厚度， 比常规的 PC薄膜 +橡胶（简称： Rubber)式按键 减少了 1mm 左右； 并且制造工艺简单、 成本低； 另外， 二次注塑的字符键 还具有凹凸的立体效果， 使其更加美观。  The character key on the button of the mobile phone in the embodiment is formed by double injection molding, thereby greatly reducing the thickness of the button of the mobile phone, and is reduced by about 1 mm than the conventional PC film + rubber (referred to as: Rubber) type button; The process is simple and the cost is low; in addition, the character keys of the overmolding also have a three-dimensional effect of unevenness, which makes it more beautiful.
实施例 2 Example 2
本实施例在实施例 1的基础上对手机按键进行了改进， 如图 3所示 ， 在 PC薄膜 1背面还进一步粘贴有软薄膜 2 , 位于 PC薄膜 1与手机导电膜 3之间。  In this embodiment, the button of the mobile phone is improved on the basis of the embodiment 1. As shown in FIG. 3, a soft film 2 is further adhered on the back surface of the PC film 1, and is located between the PC film 1 and the conductive film 3 of the mobile phone.
其中， 软薄膜 2 可以为软硅胶薄膜或软橡胶薄膜， 其厚度可以为 0. 25mm0 并且软薄膜 2的背面还设置有导电基 22。 该导电基 22的厚度可 以为 0. 3mm。具体地，导电基 22在软薄膜 2上的分布位置可以如图 4所示， 与字符键的位置相对应。 The soft film 2 may be a soft silicone film or a soft rubber film, and the thickness thereof may be 0.25 mm 0 and the back surface of the soft film 2 is further provided with a conductive substrate 22. 3毫米。 The thickness of the conductive layer may be 0. 3mm. Specifically, the distribution position of the conductive substrate 22 on the soft film 2 can be as shown in FIG. 4, corresponding to the position of the character key.
通过本实施例所述的手机按键， 由于增加了软薄膜 2及导电基 22 , 因此增 加了按键时的良好手感。 并且， 本实施例所述的手机按键的整体厚度为： 0. 25匪 （ PC 薄膜 1的厚度） + 0. 15匪（字符键 11的厚度） + 0. 25匪（软薄膜 2 的厚度） + 0. 3匪（导电基 22的厚度） =0. 95匪。 该厚度仍然能够满足薄型手 机的厚度要求。 With the mobile phone button of the embodiment, since the soft film 2 and the conductive substrate 22 are added, a good hand feeling when the button is pressed is increased. Moreover, the overall thickness of the mobile phone button of the embodiment is: 0. 25 匪 (thickness of the PC film 1) + 0. 15 匪 (thickness of the character key 11) + 0. 25 匪 (thickness of the soft film 2) + 0. 3匪 (thickness of the conductive group 22 ) =0. 95匪. This thickness can still meet the thickness requirements of thin mobile phones.
最后应说明的是： 以上实施例仅用以说明本实用新型的技术方案， 而 非对其限制； 尽管参照前述实施例对本实用新型进行了详细的说明， 本领 域的普通技术人员应当理解： 其依然可以对前述各实施例所记载的技术方 案进行修改， 或者对其中部分技术特征进行等同替换； 而这些修改或者替 换， 并不使相应技术方案的本质脱离本实用新型各实施例技术方案的精神 和范围。 Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, and The invention is not limited thereto; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions described in the foregoing embodiments may be modified, or some of the technical features may be modified.
