Description

振动马达的振动器件改进结构 技术领域
本发明振动马达的振动器件改进结构涉及振动马达，尤其是振动马达的振动块的改进结构。
背景技术
现有技术的振动马达的振动器件一般包括振动块和弹簧片，振动块和弹簧片的连接采用焊接工艺，也就是将弹簧片直接焊接在振动块上。为了保证马达振动的力度，振动块必须使用密度较大的材质，现有技术的振动块几乎所有的都是使用金属钨质材料或钨合金材料。而弹簧片则要求弹性好、质轻、密度低的材料，一般采用的是不锈钢材质。然而，钨合金材质和不锈钢材质两者的熔点属性差异很大，若两者直接用激光焊接很难保证其固定力，尤其是在频密的振动情况下。因此，因为振动块和弹簧片的开焊问题而使现有技术的振动马达经常损坏，不能使用，或者大大地降低了振动马达的使用寿命。
发明内容
本发明的目的是克服现有技术的缺陷，解决钨合金材质的振动块和不锈钢材质的弹簧片焊接的问题，以保证两者的连接牢固和稳定，大大地延长振动马达的使用寿命。
本发明的技术方案：振动马达的振动器件改进结构，包括振动块1以及与之固定连接簧片2，其特征在于：在所述振动块1有沟槽3，在所述沟槽3内有嵌块4，该嵌块4与所述沟槽3固定连接，该嵌块4材质与所述簧片2材质相近并与所述簧片2焊接。
上述的振动马达的振动器件改进结构，所述沟槽3设置在所述振动块1的边缘上。
上述的振动马达的振动器件改进结构，所述振动块1的相对的两个边缘上均设有沟槽3。
上述的振动马达的振动器件改进结构，所述嵌块4与所述沟槽3过盈配合。
上述的振动马达的振动器件改进结构，所述嵌块4与所述沟槽3浇铸连接。
上述的振动马达的振动器件改进结构，所述嵌块4与所述沟槽3压铸连接。
上述的振动马达的振动器件改进结构，在所述沟槽3的端部设有径向的台阶31。
上述的振动马达的振动器件改进结构，在所述沟槽3的端部设有径向的浅槽。
采用上述结构，在钨质的振动块中嵌入一种与不锈钢熔接点接近的金属嵌块，再将弹簧片与嵌块进行激光焊接可以很好的保证其固定强度，连接牢固和稳定，马达在做跌落试验时不会由于固定力小而脱落，从而延长马达的使用寿命。
附图说明
图1所示为本发明振动马达的振动器件改进结构的立体图。
图2所示为本发明振动马达的振动器件改进结构的主视图。
图3为图1所示各组件分解图。
具体实施方式
下面结合附图对本发明内容作进一步详述：
图1、图2、图3分别为本发明振动马达的振动器件改进结构的一实施例不同图示，包括振动块1以及与之固定连接簧片2和第二簧片7，在所述振动块1的边缘上设有沟槽3、第二沟槽5，在所述沟槽3内有嵌块4，在第二沟槽5内有第二嵌块6，该嵌块4与所述沟槽3固定连接，该第二嵌块6与第二沟槽5固定连接，所述嵌块4与第二嵌块6的材质与所述簧片2材质相近，最好是同样的材质，所述嵌块4与所述簧片2焊接，所述第二嵌块6与所述第二簧片7焊接。为保证嵌块与沟槽的固定连接，不因马达的震动而松懈，所述嵌块4与所述沟槽3、所述第二嵌块6与第二沟槽5均可采用过盈配合或者压铸连接或者浇铸连接。如此，在钨质的振动块中嵌入一种与不锈钢熔接点接近的金属嵌块，再将弹簧片与嵌块进行激光焊接可以很好的保证其固定强度，连接牢固和稳定，马达在做跌落试验时不会由于固定力小而脱落，从而延长马达的使用寿命。
为进一步保证嵌块与沟槽的连接牢度，在沟槽3的底部或端部可以设置浅槽或台阶31。该台阶31沿沟槽3的径向设置。如此可以保证嵌块4在沟槽3内压铸成型后在轴向和径向均不能移动，使嵌块与沟槽连接更牢固，可以大大地延长马达使用寿命。
本实施例中所述沟槽3为梯形槽，当然也可以是其他形状的沟槽，亦可以是容腔或盲孔等。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
