(一) 技术领域: (A) technical field:

本发明属于键盘、计算机、手持电话机等具有信息输入功能设备的技术。 The present invention pertains to a keyboard, a computer, a portable telephone having the information input and other technical features of the device.

(二) 背景技术- (B) Background -

现有的键盘(包括微型计算机、手机等设备上的键盘)不是体积过大(按键较多,输入速度较快),不便于携带,就是体积虽小(按键较少)但操作方式复杂,输入速度慢。 Conventional keyboard (keypad on the device including a microcomputer, a mobile phone, etc.) is not too large (more keys, the input speed faster), not easy to carry, that is, the volume is small (less button) but the complex operation, input slow.

为了解决这个矛盾,人们提出多种方案,都不能令人满意。 To resolve this conflict, people put forward a variety of programs are not satisfactory. example

如,在CN 2192910Y给出的键盘方案里,设计了一种可以前后拨动的按钮,可以将键盘按键占用的面积减少一些,但增加了手指操作的难度,效果并不好。 For example, the keyboard scheme CN 2192910Y given, the design of a button you can toggle back and forth, the keyboard keys can reduce some of the area occupied, but increases the difficulty of finger operation, the effect is not good. 其他使用较少按键的方案,如CN 1264982A、 CN 1365041A 、 CN 1348127A 、 CN 1288318A里的方案, 一个字符或文字往往需要更多次或更复杂的操作才能输入。 Other programs use fewer keys, such as CN 1264982A, CN 1365041A, CN 1348127A, CN 1288318A in the program, a character or word often need more time or more complex operations can be entered.

有人建议利用能提供点击力大小信号的开关作为按键或按键叠加的一部分来提高按键的输入能力(USPat 5,995, 026),但这种开 It was suggested that the use of force can provide the click switch as part of the magnitude of the signal input to improve the ability of the key or key buttons superimposed (USPat 5,995, 026), but this open

关或设计构造复杂,成本高,可靠性稳定性差,若用于键盘,需要使用与按键数量同样多的能测应力的传感器,造价会增加数倍,且其信号难于布线传输和处理,在技术和经济上很不合理,也难于微型化,多年来这些问题一直未能解决,无法实用化。 Off construction or design complexity, high cost, poor reliability, stability, if the keyboard is used, the required number of keys as many sensors can measure stress, the cost will be increased several times, and it is difficult to wire the signal transmission and processing, technical and it is economically unreasonable, but also difficult to miniaturization, for many years been unable to solve these problems, not practical.

(三) 发明内容: (C) SUMMARY OF THE INVENTION:

本发明的目的在于提出一种全新的技术方案,可以用十分简捷而廉价的措施使相关装置的键盘能更方便地输入更多种类的信息, 或使键盘的键数目减少,縮小其体积,周时不增加输入时的击键次数,并减少使用功能键带来的的麻烦,大大提高带微型键盘的装置的使用效率。 Object of the present invention is to propose a novel technical solution can be used very simple and inexpensive measures to make the keyboard device can be more easily related to a wider variety of input information, or to reduce the number of keys of the keyboard, size reduction, the peripheral without increasing the number of keystrokes are entered, and function keys to reduce the trouble caused by the greatly improved efficiency in the use of the apparatus with a miniature keyboard. 下面进行具体说明。 It is specifically described below.

本发明包括一种具有键盘输入功能的装置,至少包括结构体以及多个键,所述结构体为构架或壳体或两者的结合,承载所述的键, 所述的键为依靠按压改变开关状态或电平状况从而提供开关信号的按键,或者为依靠触摸改变开关状态或电平状况从而提供开关信号的触摸键; The present invention includes an apparatus having a keyboard input, comprising at least a plurality of keys, and the key structure, the binding structure is a framework or housing, or both, of the carrier, the pressed key is changed depend on condition or level switch state to provide a key switch signal, or to rely on a touch switch changes state or condition level to provide a touch key switch signal;

其特征在于: Wherein:

所述结构体包含至少一个承载多个所述键的承载体,其承载 The structure comprises a carrier member carrying a plurality of said at least one bond, which carries

体整体具有一定的刚性或具有一定的弹性,可平衡和传递在输入 Whole body has a certain stiffness or with a certain degree of flexibility, balance, and can transfer input

时所承载的不同的键所受触压或点击全部或部分的力或作用,承载体自身受到所述结构体部分或结构体部件的支撑; Different keys carried by an imposed contact pressure or force or click action of all or part of the carrier body itself is supported by the structure or portion of the structural member;

所述承载体的一个或多个部位或部件,或者所述结构体支撑承载体的一个或多个部位或部件,含有或附带有可以反映其所承载的键受到触压或点击时该承载体所受应力变化的应力或应变传感器或敏感元件,该应力或应变传感器或敏感元件可以与相应的信号 When one or more sites of the carrier or components thereof, or one or more portions or components of the support structure of the carrier, there may be included with or reflect it hosts by key press or click on the contact carrier changing the stress or stress or strain sensitive sensor element, the stress or strain sensitive sensor element or may be a signal corresponding

传输线路相连接,可给出相应的应力或应变测量信号或状态信号; 所述的装置可以带有内置的或外接的信号处理线路或元件或处理器或接口,可以将所述应力或应变传感器或敏感元件的应力信号放大或整理或汇总或转换或计算或编码,得到每次键受到触压时相关的测量部位或部件所受应力汇总值或其对应信号汇总值与未按键时的差值,可以根据这些数值或信号值的变化或不同,并同时根据所述不同键给出的开关信号,按照预先安排得到所对应的输入信息。 Is connected to the transmission line, gives the corresponding stress or strain measurement signal or status signal; said apparatus may be provided with internal or signal processing circuitry or a processor or interface elements or external, may be a stress or strain sensor or when stress difference signal amplification or refresh or calculated or aggregated or conversion or encoding, or to give the measurement site associated with the stress values ​​at each key member summarized by contact pressure or a signal corresponding to an aggregated value of the key is not sensitive element , may vary according to these values ​​or signal values ​​or different, and also different in accordance with the switching signal of the given key, according to pre-arranged to give the corresponding input information.

所述应力或应变传感器或敏感元件的所在位置或数目不仅不需要与所述各个键一一对应或相同,其数目还可以大大少于键的数目, 在某些情况下,甚至可以仅仅使用一个应力或应变传感器。 The location or number of stress or strain sensitive sensor element or only do not need to correspond to the respective keys or the same, that number may also be considerably less than the number of keys, in some cases, you can even use only one stress or strain sensor.

实际上,按压按键或触摸键的力会完全或部分传递给承载各个键的承载体整体,承载体整体所受应力会向承载体受到支撑的部位以及结构体支撑承载体的某些部位或部件传递,因此,这些部位或部件上的应力传感器或敏感元件都可以给出与承载体整体所受应力相关因而也与按压按键或触摸键的力相关的的应力测量信号。 Indeed, the force pressing a key or a touch key will be fully or partially transmitted to the carrier member carrier integrally respective keys, the stress bearing parts of the whole body will be supported by the carrier, and some parts of the support structure or carrier member transfer, therefore, these areas or stress on the sensor element or sensitive member may be given the stress associated with the carrier body thus integrally associated with the pressing force of the key or touch key stress measurement signals.

有时键盘(如某些手机键盘)的各个按键或触摸键的底部可以是一个共同的底板或印刷电路板。 Sometimes the keyboard (e.g. some mobile phone keypad) of the individual keys or a touch key may be a common bottom plate or printed circuit board. 需要时,所述承载体可以仅仅承载各个键的底部或与各个键的底板为一体,承受各个键受触压时传递到底部或底板的力。 If desired, the carrier may simply carry the bottom or floor of each key and each key as one, in the end force transmitting portion or the receiving plate when the contact pressure by the respective keys. 有时键帽或键的其他部分也可以通过橡胶或其他弹性材料或配件与结构体的其他部位相连接,并分散部分所受压力,此时,承载体承受的以及相关的传感器反映的可能只是按压该键的力的一部分,在信号处理时应该加以考虑。 Or sometimes other parts of the keycap bond may also be connected via a rubber or other resilient materials or parts and other parts of the structure, and the pressure on the dispersion part, this time, the carrier receiving and associated sensors may reflect only the pressing the bond portion of the force, when the signal processing should be considered.

所述装置的承载体可以设置为自身就是或在内部含有或其下面附带有或铺衬有板状或薄板状应力传感器或敏感器件。 The carrier means is provided or may be accompanied by or containing or laid beneath a plate or sheet-lined or sensitive stress sensor device is itself internally. 此类应力传感器或敏感器件可以由带有压敏电阻材料夹层的两层导电材料构成,也可以由带有弹性绝缘材料夹层的两层导电材料构成,也可以由对压力敏感的微开关矩阵触摸膜或触摸屏材料构成,可以设计为具有一定弹性的甚至带有一定柔性,便于设置在键组的下面,测量键受到的点击力。 Such stress sensor or sensing device may be composed of two layers of conductive material with piezoresistive material interlayer may be formed of two layers of conductive material with an elastic interlayer insulating material may be a pressure-sensitive touch micro switch matrix a touch screen or a film material, may be designed in the following key group, the key measurement by clicking force having a certain elasticity even with a certain flexibility, easy to set up. 一组键的承载体一般使用一个板状或薄板状应力传感器或敏感器件即可。 A set of keys of the carrier body generally use a plate-like or sheet-like device or sensitive to stress sensor.

所述装置可以及映承载体所承载的镀受到鮏压或点击时该承载体所受应力变化的应力或应变敏感元件,也可以是可以提供开关信号的应力或应变敏感开关元件。 The apparatus may be carried by the carrier and the enantiomers by plating stress of the carrier change when the stress or pressure Zheng clicks or strain sensitive elements, may be possible to provide a stress or strain sensitive switching signal of the switching element. 这样,当承载体所承载的键所受到的点击力超过规定范围时,所述应力或应变敏感开关元件会给出额外的开关信号,加上原来键受到的点击开关信号,可以按照预先安排代表输入另外一种信息。 Thus, when the key bearing member carried by the clicking force exceeds a predetermined range, the stress or strain sensitive switching element will give an additional switching signal, the original signal plus the click button switch subjected, in accordance with a prearranged representatives another input information.

实际上,输入的信息是什么不仅取决于按的是哪个键,还可以取决于触压该键的力量,因此,使用者可以在任一个键上用一次点击或触摸输入更多种类的信息。 In fact, the information entered is determined not only by what is which key, you can also touch and pressure depends on the strength of the bond, so the user can click or touch input more kinds of information on any of the key.

需要时,所述的承载体可以在有一定相互距离的接受支撑的2 个或3个或4个部位分别带有应力传感器或敏感元件。 If desired, the carrier body may be a certain distance from each other to accept the support of two or three or four positions, each with a stress sensitive element or sensor. 这样安排有利于应力測量和简化点击力计算。 This arrangement is conducive to stress measurement and simplify click force calculation.

有时候,由于承载体的结构、支撑承载体韵结构或相关.的应力或应变传感器或敏感元件结构、数目、位置的缘故,用同样的力点击同一承载体上不同位置的键,会得到不同的点击力相关测量信号或数据。 Sometimes, due to the structure, the support structure carrier rhyme or related carrier. Because of stress or strain sensitive sensor element or structure, the number, position, click on the button with the same force at different positions on the same carrier, will be different click-force-related measurement signals or data. 此时,要想反映某一位置的键的受力大小,可以根据该键的位置或开关信号对满量信号或数据作进一步的处理或运算或不同的修正或补偿,也可以预先安排在判断输入信息时,根据不同的键的开关信号,参照应力相关测量信号时依照适当的不同标准。 At this time, in order to reflect the size of the force of a position of the key, or may be further processed or operation correcting or compensating for different full-amount signal or data according to the position or the key switch signal, the determination may be prearranged when the input information, in accordance with different criteria in accordance with appropriate switch signals of different keys, with reference to the relevant stress measuring signal.

显然,按照本装置的安排,所述的很少量的应力传感器就可以反映所述各个键中任何一个所受的点击力或作用的大小,不仅仅结构简单,成本低,其信号也更容易汇总和处理。 Obviously, the device according to the present arrangement, the small amount of stress sensor can reflect the size of a force or action suffered click the respective keys any, only simple structure, low cost, its signal is also easier aggregation and processing.

所述的结构体上可以有对所述的应力或应变传感器或敏感元件给出的应力測量信号或其误差进行直接或间接调节或校正或补偿操作或发出其指令的旋钮或键。 Can have the structure of the stress or strain or stress measurement error sensor signal analysis or sensitive element directly or indirectly regulate or correct or compensate for the instruction issued by the operator or knob or key. 这样,如果所述应力传感器的输出特性或其他部件发生变化,可以方便地消除不利影响。 Thus, if the output characteristics of the sensor or other component of stress change can easily eliminate the adverse effects.

在特别简单的设计线路中,使用的应力传感器可以是廉价的应力敏感电阻,其电阻值随着应力的增加而减小。 In a particularly simple circuit design, the stress sensor used can be inexpensive stress-sensitive resistor, its resistance value decreases with increasing stress. 可以将分散分布的几个应力敏感电阻以并联或串联方式联结,以其总电阻值的变化反映各应力之和的变化,更便于处理或计算。 Several stress sensitive resistors may be dispersed and distributed in parallel or in series coupling, the total change in its resistance value and each reflects the change in stress, easier processing or computing.

使用的应力传感器还可以是廉价的压力敏感电容,其电容值随着压力的增加而增加或减少。 Stress sensor may also be used a pressure-sensitive inexpensive capacitors, the capacitance value increases as the pressure is increased or decreased. 可以将分散分布的几个压力敏感电容以并联或串联方式联结,以其总电容值的变化反映各应力之和的变化,更便于处理或计算。 Some may be distributed along the pressure sensitive capacitance coupled in parallel or in series, the total capacitance value of its change reflects the change in stress and respective easier processing or computing.

所述的装置可以带有内置的或外接的信号处,路或处理器或其他线路或计算装置,可将每次某一键受到触压时所述传感器或敏感元件的应力信号或其汇总值或其放大值或其计算数据或处理值与此前没有任何键受到触压时的相应信号或数值或数据进行比较,得到其差值或增量或它们的最大值,可以据此并同时根据所述不同的键给出的开关信号,得到所对应的输入信息。 When the signal at the device may be provided with internal or external, lines or other circuit or processor or computing device, may each be a key or a contact pressure of the aggregated value of the sensor stress signal or sensitive element calculated amplification value thereof or a processed value with the previous data or not any key or by a signal corresponding to the data value or contact pressure compared to obtain the difference or increment or a maximum value thereof, and accordingly may be simultaneously in accordance with the different switching signals of said given key, to give the corresponding input information.

用差值或增量或它们的最大值作参考输入信息,有利于减少传感器或其他元件特性漂移以及某些机械作用变化可能带来的对测量或输入准确率的不利影响。 Reference input information with the maximum difference or increment thereof, or help to reduce the adverse effects of sensor drift or other elements and certain mechanical properties may bring to effect changes or the measurement accuracy of input.

需要时,可以将上述传感器输出的模拟信号经A / D变换元件转换成数字信号,再输入处理器按程序进行求和、存储、修正、比较、 判断、编码及其他运算和处理。 If desired, the sensor may output an analog signal after A / D conversion element is converted into a digital signal, then the input processor programmed to sum the stored, modified, comparison, judgment, and arithmetic coding and other processing. 所述的装置可以带有内置或外接的音响信号或光学信号发生部分,可以利用音响的力度或音调或音色等特征或者发光的亮度或颜色或图形或发光位置的变化,来提示或反映或表达或响应各个键或承载体所受触压力大小或变化或不同,或者所触压的键位置的不同, 或者提示所输入的为何种信息。 An optical or acoustic signal portion of the signal generating means may be provided with internal or external, may be utilized, or the intensity of sound or tone, or timbre characteristics or changes in brightness or color graphics or luminescence emission position, or to reflect or to prompt the expression each key or in response to a touch pressure or size of the carrier or suffered variations or different, or a different key positions of the contact pressure, or suggesting what information is input.

令所述承载体的一个或多个部位或部件,或者所述结构体支撑承载体的一个或多个部位或部件,含有或附带有可以反映其所承载的键受到触压或点击时该承载体所受应力变化的应力或应变传感器或敏感元件,该应力或应变传感器或敏感元件可以与相应的信号传输 When the carrier so that a plurality of body portions or members or, or the structure of support or a carrier member or a plurality of locations, with or may reflect key comes with its contact pressure being carried by the carrier or click stress body or the stress or strain sensitive sensor element, the stress or strain sensitive sensor element or respective signals may be transmitted and
