琴键承托式支撑架
技术领域
本发明涉及支撑架结构， 具体涉及用于 7 托钢琴辅助指导装置的支撑架。
背景技术
随着社会的进步， 精神生活越来越受到人们的重视。 例如， 越来越多的人 学习弹钢琴、 电子琴等。 在学习弹奏的时候， 要能读懂琴谱， 找到正确琴键， 以及在弹奏现有节拍的同时还需要考虑一下节拍， 要弹得流畅， 这三种处理必 须同时进行， 而没经过长时间训练的人是不可能做到的。 初学者往往不熟悉琴 谱、 琴键， 不会控制节奏， 出错的时候也得不到及时纠正， 导致弹奏的过程枯 燥乏味， 缺乏效率， 也难以体会到自己弹出动听音乐的乐趣。
有鉴于此， 本申请人发明出了一种乐器弹奏指导装置 （详见申请号为
201120249007.9的实用新型专利）。 使用时， 其放置在琴键上， 初学者只需跟随 着发光二极管显示板上的指示按下相应的琴键， 就能弹奏出流畅的音乐。
但是， 上述的乐器弹奏指导装置的摆放位置容易出现偏差， 从而误导初学 者的弹奏。
发明内容
本发明的目的在于提出一种琴键承托式支撑架， 其能解决现有的弹奏指导 装置摆放在琴键上时， 容易出现偏差的问题。
为了达到上述目的， 本发明所采用的技术方案如下：
琴键承托式支撑架， 其包括一用于承托弹奏指导装置的壳体的承托平板； 承托平板的顶面向上延伸有二个用于支撑弹奏指导装置的壳体背面的支撑杆， 以及一个可与弹奏指导装置的壳体底部的定位凹槽相匹配的定位凸块； 二支撑 杆分别位于承托平板的左右两侧， 定位凸块位于二支撑杆之间； 承托平板的底 面向下延伸有定位卡块， 定位卡块的宽度与一琴键的三黑键与二黑键之间的间 隙相匹配； 承托平板的底面与琴键的黑键接触。
为了使支撑更稳定， 支撑杆的截面为三角形， 且支撑杆的斜边与承托平板 的夹角为钝角。 承托平板的厚度沿承托平板的前侧至支撑杆的斜边逐渐减小。
为了增强承托平板的强度， 承托平板的顶面还向上延伸有加强筋， 二个支 撑杆通过加强筋连接。
为了消除琴键反弹时与承托平板碰撞而产生的噪音， 承托平板的底面还覆 盖有一消音层， 消音层采用消音材料或放音材料制作而成， 例如软质材料。
具体的， 琴键承托式支撑架与弹奏指导装置结合的一种实现方法为： 所述 弹奏指导装置的壳体内安装有单片机， 与单片机相连的存储卡、 选择控制单元 以及发光二极管显示板； 壳体为一长方体形状； 发光二极管显示板上的若干发 光二极管组与琴键对应。
具体的， 琴键承托式支撑架与弹奏指导装置结合的另一种实现方法为： 所 述弹奏指导装置的壳体内安装有发光二极管显示板； 壳体为一长方体形状； 发 光二极管显示板上的若干发光二极管组与琴键对应； 所述弹奏指导装置的单片 机、 存储卡安装在承托平板上， 弹奏指导装置的选择控制单元、 存储卡、 发光 二极管显示板分别与单片机电性连接， 选择控制单元位于承托平板及弹奏指导 装置的壳体外侧。 为了方便安装， 承托平板的顶面还向上延伸有一芯片安装盒， 弹奏指导装置的单片机、 存储卡均位于芯片安装盒内； 芯片安装盒上设置有接 触弹片， 接触弹片与单片机电性连接， 弹奏指导装置的壳体背面设置有接触触 点， 所述接触触点与发光二极管显示板电性连接； 当弹奏指导装置的壳体的定 位凹槽与定位凸块插接时， 接触触点与接触弹片连接。 为了扩展弹奏指导装置 的功能， 承托平板的顶面还向上延伸有至少一个功能组件插槽口， 所述功能组 件插槽口内安装有电路触点， 电路触点与单片机电性连接； 一个功能组件插口 与一个功能组件插体插接， 功能组件插体的电性触片与电路触点连接。 所述功 能组件插体为记忆卡或电源模块或放音器。
本发明具有如下有益效果：
定位凸块与定位卡块的相互配合， 可以实现弹奏指导装置的发光二极管显 示板与琴键精确对位， 消除了现有技术的偏差问题， 定位卡块还具有防止承托 平板滑动的效果， 定位凸块防止弹奏指导装置的壳体滑动的效果。 而且承托平 板压在所有琴键的黑键上， 分散了重力， 避免了黑键被压低； 承托平板底面上 的消音层可有效防止弹奏者按下黑键后黑键弹起敲击承托平板而发出的不必要 响声。 附图说明

承托平板 2的顶面还向上延伸有加强筋 23 , 二个支撑杆 22通过加强筋 23 连接。
承托平板 2的底面还覆盖有一消音层（图未示 ), 消音层采用消音材料或放 音材料制作而成， 例如软质材料。
弹奏指导装置的壳体 300内安装有发光二极管显示板 301 ;壳体 300为一长 方体形状； 发光二极管显示板 301上的若干发光二极管组与琴键 200对应， 发 光二极管显示板 301可在壳体 300的正面显示出来； 所述弹奏指导装置的单片 机 303、 存储卡 304安装在承托平板 2上， 弹奏指导装置的选择控制单元 302、 存储卡 303、发光二极管显示板 301分别与单片机 303电性连接， 选择控制单元 302位于承托平板 2及弹奏指导装置的壳体 300的外侧，即单片机 303向外引出 一导线 800, 选择控制单元 302通过导线 800与单片机 303连接（实际上， 根据 设计要求， 选择控制单元 302还可以安装在壳体 300上或者安装在支撑架 22的 侧面上）。 具体的， 承托平板 2的顶面向上延伸有一芯片安装盒 25 , 弹奏指导装 置的单片机 303、存储卡 304均位于芯片安装盒 25内； 芯片安装盒 25上设置有 接触弹片 251 , 接触弹片 251与单片机 303电性连接， 弹奏指导装置的壳体 300 背面设置有接触触点（图未示）， 所述接触触点与发光二极管显示板 301电性连 接； 当弹奏指导装置的壳体 300的定位凹槽（图未示）与定位凸块 21插接时， 接触触点与接触弹片 251连接。 当然， 为了解决供电问题， 芯片安装盒 25上还 可以有一电源插口 305 , 电源插口 305 与单片机电性连接（实际上， 电源插口 305还可以设置在 7 托平板 2的其他地方， 详见实施例三）。
本实施例的安装过程与实施例一相同。
实施例三
