Description

具有盖体的装置
本申请要求于2021年6月9日提交至中国国家知识产权局、申请号为202110645310.9、申请名称为“具有盖体的装置”的专利申请的优先权。
技术领域
本申请涉及生活电器技术领域，具体涉及一种具有盖体的装置。
背景技术
现有技术中的电饭煲，煲盖和煲身之间通常通过铰接轴相连，煲盖可以打开和关闭。为满足多个零件之间的装配误差，以满足开合盖要求，煲盖和煲身之间会留有1mm左右间隙。

实施例1
现有技术中的电饭煲，煲盖和煲身之间通常通过铰接轴相连，煲盖可以打开和关闭。为满足多个零件之间的装配误差，以满足开合盖要求，煲盖和煲身之间会留有1mm左右间隙。
由于电饭煲是由多个零件装配形成的，实际生产过程中零件误差会影响煲盖与煲身之间的间隙大小。当间隙较大会影响外观，间隙较小会导致不能正常开合盖。因此，对零件精度要求非常高，增加了零件的制造难度，零件报废率高，给生产带来了很大的困扰。
为此，本实施例提供一种具有盖体的装置，可减少对零件的精度要求，具有盖体的装置可以为电饭煲、电压力锅、高压锅、电热饭盒、电压力煲等。在一个实施方式中，如图1所示，具有盖体的装置包括主体结构、与主体结构通过铰接轴4铰接的盖体、驱动组件。当具有盖体的装置为电饭煲时，主体结构为煲身1，盖体为煲盖3。
其中，驱动组件能够在盖体盖合在主体结构上时，驱动盖体朝向主体结构移动。
在本实施方式中，通过设置驱动组件，在盖体盖合在主体结构上时，驱动组件驱动盖体朝向主体结构移动，从而可减少盖体和主体结构之间的间隙，使其整体外观更美观。在加工时，即使构成具有盖体的装置的零部件的精度较低，也能够使盖体和主体结构之间的间隙较小，因此，可减少对零件的精度要求。
在上述实施方式的基础上，在一个优选的实施方式中，如图2和图3所示，主体结构上设有第一条形孔7，第一条形孔7的长轴直径的延伸方向的夹角为A，0°≤A＜90°，铰接轴4设在盖体上，且铰接轴4穿设在第一条形孔7中，驱动组件能够使铰接轴4在第一条形孔7中朝靠近主体结构的方向移动。在本实施方式中，铰接轴4在驱动组件的驱使下朝靠近主体结构的方向移动会带动盖体朝靠近主体结构的方向移动，从而减少盖体和主体结构之间的间隙，第一条形孔7的设置可对铰接轴4的移动起导向作用，对盖体上下浮动起避让作用，同时在主体结构上加工第一条形孔7与现有技术中加工圆形的轴孔相比，可大大减少对零件的精度要求。
具体的，当A为0°时，第一条形孔的长轴直径沿竖直方向延伸，当0°＜A＜90°时，第一条形孔倾斜设置。
铰接轴4可固定设置在盖体上，也可在盖体上设置轴孔，轴孔与铰接轴4的形状相适配，铰接轴穿设在轴孔及第一条形孔7中。

在上述实施方式的基础上，在一个优选的实施方式中，如图2所示，驱动组件还包括第一顶杆6，第一顶杆6的第一端与第一弹性件5的第二端连接，第一顶杆6的第二端适于与铰接轴4抵接。在本实施方式中，安装时，使第一弹性件5发生弹性形变，第一弹性件5的弹 性力可驱动第一顶杆6朝靠近主体结构的方向移动，第一顶杆6朝靠近主体结构的方向移动的过程中带动盖体朝靠近主体结构的方向移动，从而减少盖体和主体结构之间的间隙。
在上述实施方式的基础上，在一个优选的实施方式中，进一步参考图2，第一顶杆6的第二端设有U型槽，U型槽与铰接轴4抵接。在本实施方式中，U型槽的设置便于第一顶杆6与铰接轴4抵接，对铰接轴4施加压力。在其他可替换的实施方式中，可不设置U型槽，第一顶杆6的第二端与铰接轴4相抵。
