具体实施方式
本公开内容本实施例提供一种电器设备、开关门装置及其离合器的控制方法,旨在一定程度上提升开关门操作的效率和便捷性,并同时一定程度上解决人工开启冰箱门初始阶段阻力较大,后续阶段转动过快,开关门过程不流畅的问题。
本公开内容涉及的开关门装置用于装配到配置有可偏转开启和闭合的门体的电器设备上,通过开关门装置的动作驱动门体的开启和闭合。该设备可以为冰箱,消毒柜,洗碗机等电器设备。
参见图1,该电器设备包括箱体910和转动地设置在箱体910上的门体920,箱体910上设置有取物口,操作门体920在箱体910上转动,以关闭或打开箱体910的取物口。
参见图1,在一些实施例中,开关门装置可包括:驱动机构100、转门机构200和顶门机构300。其中,驱动机构100输出驱动力,可驱动转门机构200和顶门机构300实施门体920的全程转动操作和初始顶门操作;也就是说,本实施例的转门机构200和顶门机构300均是由驱动机构100驱动的,均由驱动机构100提供驱动力。且驱动机构100包括提供动力的驱动器110以及分别与顶门机构300和转门机构200相连的联动齿轮120,从而驱动器110通过联动齿轮120驱动顶门机构300和转门机构200相对于底座600偏转;驱动机构100还设置有离合装置400,用于连接在联动齿轮120和驱动器110之间,实现可分离的连接,建立或者切断联动齿轮120和驱动器110的连接,从而能够灵活控制驱动器110与顶门机构300以及转门机构200之间的传动路径的通断。从而避免在手动开关门时,顶门机构300和转动机构200与驱动机构100相互干涉,以及在装置故障或者环境干扰时都能够切断驱动机构100的连接,保证装置结构的安全性,避免机械损伤。
参见图10和图12,在一些实施例中,可将转门机构200或顶门机构300分别与驱动机构100配合设置,用于单独实施开关门结构方案或者顶门结构方案。本实施例的顶门机构300与驱动机构100相配合,以突破门体920与箱体910的吸附阻力,负压力等开门阻力,以将门体920顶开的预设角度,以便于后续自动或者手动开门操作。顶门机构300包括联动件310和转动连接在其上的顶门件,且联动件310转动地设置在底座600上;转 门机构200包括:转动连接在底座600上的带动件210以及与带动件210转动连接的转门件220,且转门件220还与门体920铰接;联动齿轮120分别与带动件210和联动件310相连。
参见图1,在一些实施例中,为了满足装配精度需求,或者实现高效装配,可以在箱体910上设置一单独的底座600,用于承载上述驱动机构100、转门机构200和顶门机构300,从而可以将驱动机构100、转门机构200和顶门机构300装配在底座600上,再将底座600整体装配在箱体910上,在电器设备上实现基于底座600的标准化安装,保证其安置稳定性的同时还能够保证配合精度和可靠性;另一方面,在底座600整体装配到冰箱等电器设备上时,由于可以整体安装,高效且可靠。
在本实施方式中,底座600为设置在箱体910内的一单独部件;在其他实施方式中,底座600也可以为箱体910的一部分,成型在箱体910上,而非单独部件。
值得说明的是,输出功率不变的情况下,输出力道与速度成反比;因此,在保持驱动功率不变的情况下,能够在顶门阶段以较低的门体偏转速度获得较大的顶推力道,从而能够顶门机构300迅速可靠的顶推开门体920,当转门机构200投入后,由于转动阻力很小,从而能够保持较小转门力道的情况下获得较高的转门速度,从而快速完成转门操作,实现开门到位。
参见图1、图15、图22和图25,离合装置400控制驱动机构100与顶门机构300和转门机构200之间的传动连接关系,有效适应手动开关门和自动开关门的不同需求,以及各类机械故障,提升装置结构的可靠性和使用安全性。还可设置角度采集单元500,用于实时监测联动齿轮120转动角度,并可将转动角度信息作为反馈控制开关门装置动作的依据,进一步提升自动控制可靠性。
在一些实施例中,离合装置400设置有可分离第一传动组件410和第二传动组件420,分别连接联动齿轮120和驱动器110,从而通过第一传动组件410和第二传动组件420的连接和分离实现驱动器110与联动齿轮120的传动关系的连接和中断;为了可靠实现离合状态的切换,离合顶推组件430推动第一传动组件410和第二传动组件420的连接和分离。
在一些实施例中能够,还可以将联动齿轮120的转动角度值控制驱动器110的启停及正反转等。从而能够整体直接控制驱动器110,保证控制效率。
在一些实施例中,还可将联动齿轮120的转动角度值控制离合顶推组件430动作,实现第一传动组件410和第二传动组件420的连接和分离操作的反馈控制。
在一些实施例中,角度采集单元500可作为开关门装置的组件,装配在底座600上,可设置为各种类型的角度传感器,检测联动齿轮120相对于底座600的转动角度;可采用磁电式角度传感器,磁敏角度传感器,或者光电式角度传感器亦或者角度编码器等。
在一些实施例中,角度采集单元500可设置成连接在箱体910和门体920之间的行程开关,角度传感器,用于直接检测门体920相对于箱体910的角度位置,并反馈给开关门装置实施驱动机构100的控制。
在一些实施例中,在执行开关门操作时,可通过角度采集单元500跟踪检测联动 齿轮120的偏转角度,且偏转角度可设置成矢量角度,即可以区分联动齿轮120的偏转方向,正转和反转,并实时回传检测值给开关门装置的控制元件,实施驱动器110和离合顶推组件430的控制。
在一些实施例中,联动齿轮120作为直接驱动转门机构300和顶门机构300的元件,其驱动方式应当同时满足可偏转的顶门机构300和顶门机构300的动作模式。下面具体介绍联动齿轮120的详细结构。
参见图14、图15、图16、图17和图18,在一些实施例中,可将联动齿轮120的本体设置成在底座600上的转动件,设置有与上游驱动器110啮合衔接的第三齿部121,通过转动输出扭矩的方式驱动顶门机构300和带动件210。为满足带动件210的驱动需求,可在本体上相对设置第一顶推部1231和第二顶推部1232,且两者间留有足够容纳带动件210的空间,从而实际装配状态下,能够分别通过第一顶推部1231和第二顶推部1232从带动件210的两侧顶推带动件210转动,从而在联动齿轮120的本体正向和反向转动时,分别顶推带动件210沿两个相反方向转动,从而带动转门件220顶推或者拉动门体920,实现开门和关门操作。
在一些实施例中,可将第二顶推部1232设置成开门顶推部,第一顶推部1231设置成关门顶推部;即,在联动齿轮120正向转动时,通过第二顶推部1232将带动件210推向门体920以推动转门件220顶推门体920实现开门;在联动齿轮120反向转动时,通过第一顶推部1231将带动件210推离门体920以推动转门件220拉动门体920实现关门。
在一些实施例中,在开门过程中,为了满足先实施顶门操作而后实施转门操作的时序控制,可将第一顶推部1231和第二顶推部1232的间距进行匹配设计,留出一定的偏转空间,使得带动件210相对于本体偏转时,从第一顶推部1231转动到第二顶推部1232需要转动第一角度,从而可通过设置带动件210的初始位置,使得联动齿轮120偏转与带动件210受推偏转之间存在时间差,从而在开门过程中,当联动齿轮120转动并带动顶门机构300实施顶推操作时,转门机构200并不同时实施主动转门操作,而是延迟一段时间,才由转门机构200在联动齿轮120的带动下实施主动转门操作。
在一些实施例中,可将带动件210的初始位置设置为抵靠在第一顶推部1231上,从而在开门过程中,联动齿轮120开始转动后,带动件210自第一顶推部1231逐步趋近第二顶推部1232,从而能够精确控制第二顶推部1232顶推带动件210的时间,使得转门机构200和顶门机构300无缝衔接,流畅开门,避免卡顿,震动等不良配合缺陷。
可根据门体920的设计开度,匹配设置带动件210的偏转角度以满足转门需求,对应控制在第一角度。第一角度的取值还与带动件210的初始位置和长度等相关,可根据实际的装配工况调配设置。
参见图1、图10和图19,在一些实施例中,为了提升带动件210的位置控制精度,避免带动件210失位,可在底座600上设置第二止挡件620,避免其过度偏转。可将第二止挡件620设置在第二顶推部1232与第一顶推部1231之间,可将带动件210的初始位置设置在抵靠在第一顶推部1231用于将带动件210限制在第二止挡件620与第一顶推部1231之间,保证其初始位置的可靠性。可根据带动件210的宽度及其预设的初始位置,参照第 一顶推部1231的初始位置,以第二止挡件620和第一顶推部1231之间的距离略大于带动件210的宽度为标准,设置第二止挡件620的位置。
在一些实施例中,还可在第二止挡件620上设置匹配带动件210的侧壁型面的止挡型面621,保证止挡状态下,带动件210的受力均匀性,避免局部受力集中,造成结构损伤。
在一些实施例中,为了提升带动件210的转动控制精度和可靠性,可将本体和带动件210的第一端同轴且可转动地设置在底座600上,从而能够通过控制本体的转动角度实现对带动件210的角度控制,极大地提升了便捷性。在其他实施例中,带动件210的第一端也可不与本体同轴设置,仅将带动件210枢转连接在联动齿轮120的本体上,形成类似曲轴驱动的结构;还可以将带动件210转动设置在底座上,同时伸出两个推臂并将两个推臂上分别设置第一顶推部1231和第二顶推部1232并将带动件210布置在梁推臂之间,实现顶推操作,具体可根据实验确定配合布置的位置和结构规格。
在一些实施例中,为驱动顶门机构300,联动齿轮120的本体上设置有第三顶推部122,用于连接并驱动顶门机构300。开门操作时,联动齿轮120的本体正向转动,并驱动顶门机构300推动门体920。相对的,关门操作时,联动齿轮120的本体反向转动,带动顶门机构300复位。
在一些实施例中,顶门操作仅需要突破门体920和箱体910之间的吸附力为主的开门阻力,将门体920顶开较小角度,为此顶门机构100的顶推行程也较小;相应的,联动齿轮120连接以及顶推顶门机构100的行程和时间也可以仅设置为相对较短的顶门过程中,即在转门机构200主动转门后,顶门机构100可断开与联动齿轮120的连接或者仅仅继续保持较小时间段后分离,简化工作状态下的结构联动状态,避免相互干涉。
参见图15,为了提升连接和断开的时间控制精度和可靠性,顶门机构100上可设置第一齿部313,第三顶推部122上设置有与第一齿部313啮合传动的第二齿部1221,从而通过啮合传动的方式稳定驱动,同时还能够通过控制啮合齿部的长度,齿数以调整顶推行程。在开门过程中,联动齿轮120正向转动,即通过啮合传动方式驱动顶门机构100顶推门体920,直至解啮合,顶门机构100将不再受力;在关门过程中,联动齿轮120反向转动,转动设定角度时,重新建立第一齿部313和第二齿部1221的啮合连接,而后顶门机构100在联动齿轮120的带动下沿反顶门方向移动,直至复位。
在一些实施例中,可基于带动件210的偏转控制实现顶门机构100的顶门行程控制。具体可将第一齿部313与第二齿部1221开始啮合到分离的时间段内联动齿轮120所转动的角度设置为第二角度。考虑到第一角度为联动齿轮120的本体开始转动时,本体相对于带动件210所转动的角度,即相对于本体开始正转时,转门机构200实施转门所延迟的时间段,为此可将第一角度按照小于等于第二角度控制,即基于此控制啮合时间段,从而控制啮合齿部的长度。
在一些实施例中,为了保证顶门和转门过程的衔接顺畅性,可将第一角度与第二角度之间的差值控制在1度以内。即带动件210抵触到第二顶推部1232时,第一齿部313与第二齿部1221仍然保持一小段啮合的啮合状态,或者保持最后一个啮合齿对。
参见图14和图16,在一些实施例中,为了平稳控制带动件210的偏转姿态,可在联动齿轮120的本体上开设转动限位槽123,并保持联动齿轮120的本体与带动件210同轴转动地设置在底座600上,且可将同轴转轴211可设置在转动限位槽123内,并将带动件210转动地设置在转动限位槽123内,且将第一顶推部1231和第二顶推部1232设置成转动限位槽123在联动齿轮120的径向方向上的槽壁,即设置成类扇形槽。通过转动限位槽123容纳带动件210,降低整体装配高度,同时沉槽结构也能够有效保护带动件210顶推区域的抗冲击,震动的性能,保证结构的可靠性。
在一些实施例中,为了保证带动件210抵靠在第一顶推部1231为初始位置,并抵抗震动影响其位置和姿态,可设置一复位弹簧240,并将其两端分别连接在联动齿轮120的本体与带动件210上,在带动件210与第一顶推部1231之间保持拉紧力,形成相互靠近的趋势;同时,在门体920开启后引导带动件210抵靠在第二顶推部1231上。在其他实施例中,复位弹簧240也可替换成簧片,或者其他弹性减材料,通过弹性顶推,拉紧等方式实现限位。
在一些实施例中,为了便于固定,可在带动件210上设置第一固定座212用于固定复位弹簧240的第一端部;还可在联动齿轮120的本体上设置第二固定座125,固定复位弹簧240的第二端部。
参见图16,考虑到复位弹簧240的形变特性,在联动齿轮120的本体上开设复位弹簧容置槽124,并将复位弹簧240设置在其内,不仅可实现复位弹簧240在联动齿轮120上的装配,还可避免外界对复位弹簧240冲击刮蹭,保证其形变状态的稳定性。在本实施例中,还可将复位弹簧容置槽124设置成类扇形槽型,靠近转动限位槽123的一侧宽度相对更大,从而适应带动件210的偏转过程,避免复位弹簧240抵触弯折形变。
在一些实施例中,为了提升联动齿轮120功能的稳定性和到位可靠性,可在底座600上设置第三止挡件641和第四止挡件642,分别布置在联动齿轮120的转动轨迹两端,阻止其过度转动,保证正向转动和反向转动的到位精度。在门体920关闭时,第三止挡件641止挡联动齿轮120转动,在门体642打开到极限位置时,第四止挡件642止挡联动齿轮120转动。
在一些实施例中,可根据门体920的设计开度确定联动齿轮120的转动极限角度,可将联动齿轮120在第三止挡件641和第四止挡件642之间的转动角度设置成130度90度以上;可设置成120度或者其他具体度数。
参见图14,在一些实施例中,为了保证带动件210的平衡姿态,可在带动件210的端部设置延伸限位部213,通过延伸限位部213顶抵在底座600上,避免单侧翘起。在其他实施例中,还可在延伸限位部213上设置自润滑材料层,降低接触摩擦系数。
下面具体描述离合装置400的结构。
参见图2、图3、图4和图5,本申请实施例提供的离合装置400具体设置有可连接且可分离的第一传动组件410和第二传动组件420,用于分别对应连接上游结构和下游结构,实现上游结构和下游结构的稳定可靠的连接和分离;本实施例中,实现开关门装置中上游的驱动机构100同下游的转门机构200和顶门机构300之间的连接和断开。
为了实现第一传动组件410和第二传动组件420的连接和分离状态的切换,离合装置400还设置有离合顶推组件430,用于推动第一传动组件410和第二传动组件420相互靠近连接或者相互远离分离。可在第一传动组件410和第二传动组件420上分别设置相配合的衔接结构,实现第一传动组件410和第二传动组件420的稳定连接和便捷分离。
在一些实施例中,离合顶推组件430设置有可套设在第二传动组件420上的顶推套431。在装配时,将第二传动组件420嵌设在顶推套431内,用于稳定固定第二传动组件420的同时,可通过推动顶推套431间接推动第二传动组件420移动,从而避免直接接触第二传动组件420,从而避免影响第二传动组件420的运行状态;还可以通过整体推动第二传动组件420实现保证第二传动组件420的结构稳定性。
离合顶推组件430还设置有用于配合推动顶推套431的推杆432,通过推杆432沿第一方向移动顶推套431,整体推动第二传动组件420靠近第一传动组件410,建立连接;或者通过操作推杆432,促使顶推套431沿第一方向的反向移动,使得第二传动组件420远离第一传动组件410,断开连接。
参见图2和图5,在一些实施例中,第二传动组件420设置有第一传动件421,可与第一传动组件410传动相连。并可在第一传动件421上设置连接端4211,用于连接第一传动组件410;还可在第一传动件421上设置顶推端4212,用于配合嵌设在顶推套431内,从而形成稳定的固定结构。相应地,连接端4211可凸出于顶推套431,保证连接端4211顺畅连接第一传动组件410。
参见图6、图7、图8和图9,在一些实施例中,为了提升第一传动组件410与连接端4211的连接和分离的顺畅性和便捷性,可在第一传动组件410上开设可配合容纳连接端4211的卡槽411,且卡槽411的形态可设置成配合卡合连接端4211的结构形态,从而能够通过单向顶推的操作,便捷的卡嵌过程建立连接稳定的连接传动配合状态,保证传动状态的可靠性;同时,在断开连接时,也能够通过便捷的单向推离实现迅速顺畅地分离,还可降低对第一传动件421和第一传动组件410的状态和结构稳定性的影响。
在一些实施例中,基于单向靠近和远离的卡合和分离操作,可在卡槽411的槽壁面上设置内齿413,相配合的,可在连接端4211的外周面上设置外齿4215,随着第一传动件421的移动,实现内齿413和外齿4215的啮合和解啮合。
在一些实施例中,为了适应某些工况下第一传动件421的转动状态下的啮合需求,可将卡槽411内的相邻两个内齿413之间的间隙设置成大于外齿4215的宽度,从而具备足够大的适应空间,便于外齿4215的嵌合到位,以高效建立啮合连接状态。
在一些实施例中,可将相邻两个内齿413之间的间隙设置成外齿4215的宽度两倍以上。
在一些实施例中,连接端4211的外周面上相邻两个外齿4215之间的间隙也可设置成大于内齿413宽度,从而具备足够大的适应空间,便于内齿413的嵌合到位,以高效建立啮合连接状态。
在一些实施例中,可将相邻两个外齿4215之间的间隙设置成内齿413的宽度两倍以上。
在一些实施例中,第一传动组件410可采用啮合传动的方式建立与其他结构的传动关系,可将第一传动组件410设置成第一传动齿轮,相应地,可将卡槽411开设于所述第一传动齿轮的轴向端部。第一传动件421沿第一传动齿轮的轴向移动,实现连接和分离。
在一些实施例中,为了适应第一传动齿轮的转动的工作状态,可将卡槽411设置成圆形槽,内齿413可等间距布置在圆形槽壁面上,且数量至少两个;可将齿413的数量设置成六个,八个,具体数量可根据卡槽411规格设置。相配合的,连接端4211的外型面也可设置成圆形,外齿4215可等间距布置在圆形槽壁面上,且数量至少两个;可将齿413的数量也可设置成六个,八个;具体数量可与内齿413的数量相同。
第一传动齿轮的中心轴孔412与圆形的卡槽411同轴设置,保证内齿413的啮合效率和稳定性。可在中心轴孔412的孔口同轴设置延伸筒414,便于配合内嵌的转轴稳定固定到底座600上。
在一些实施例中,由于顶推端4212内嵌于顶推套431内,当第一传动件421转动时,由于接触面过大,极易造成转动姿态不稳定,磨损量过大的情况,可在外周面上设置有多个间隔设置的限位凸台4216,将顶推套431的内型面和顶推端4212的外周面间隔开,留下一定均匀的间隙,极大地缩小接触面积,降低磨损程度,保证第一传动件421的转动姿态的稳定性。
在一些实施例中,限位凸台4216滑动地抵触在顶推套431的内表面上,从而能够进一步降低磨损程度。可在限位凸台4216上设置自润滑材料层,降低摩擦系数,提升耐磨性,延长使用寿命。
在一些实施例中,还可进一步在限位凸台4216的外周面上设置间隔布置的凸起,进一步降低接触面。
在一些实施例中,为了实现稳定推动第一传动件421,还可在第一传动件421上设置支撑凸缘4213,用于搁置在所述顶推套431的端面上。可将支撑凸缘4213设置在连接端4211和顶推端4212之间。一般可将传动件421一体成型,也不排除分别开模成型后装配到一起。
在一些实施例中,为了保证结构强度,第一传动件421、顶推套431等往往需要一定的厚度;在装配之后,整体高度往往较高,所需要的装配空间也相应较大。为此,可在顶推套431的端面上设置有沉台4313,用于容纳支撑凸缘4213,缩减整体高度。一定程度上,也能够维持第一传动件421的转动轴线的稳定。
在一些实施例中,为了满足第一传动件421与上游结构的传动连接需求,需要设置成在第一传动件421上设置连接结构。因此,第二传动组件420还设置有第二传动件422,用于驱动第一传动件421并与上游结构相连,实现传动力矩的传递。
在一些实施例中,考虑到第一传动件421需要沿第一方向移动,且还需要满足力矩传递,第一传动件421可套设于第二传动件422上并可随着第二传动件422转动,实现力矩传递;同时,可沿着第一方向相对于第二传动件422移动。
在一些实施例中,为了实现第一传动件421与第二传动件422相对滑动且满足跟随转动,第一传动件内表面4214上开设有轴向通槽4217,第二传动件外表面4221上设置 有可嵌设在轴向通槽4217内的卡块4222,从而能够实现第一传动件421跟随第二传动件422转动。同时,卡块4222还可沿着轴向通槽4217滑动,从而满足第一传动件421相对于第二传动件422沿第一方向滑动。
为了满足扭矩传递需求,可在第二传动件422内同轴固定传动轴423,用于连接上游驱动器110,驱动第二传动件422。
在一些实施例中,为了满足传动轴423固定到第二传动件422内,可在第二传动件422上开设传动轴孔4223,并在传动轴孔4223设置第一限位面4224,在传动轴423的外周面上设置第二限位面4231,当传动轴423嵌于传动轴孔4223内时,第二限位面4231与第一限位面4224抵触,从而限制传动轴423相对于第二传动件422转动。
在一些实施例中,为了满足工艺性需求和简化成型工艺,传动轴423可设置成圆柱形件,圆柱形件的外圆周面上设置切向平面,形成第二限位面4231。相配合的,传动轴孔4223设置成相配合的形态。
在一些实施例中,第一传动组件410与第二传动件422同轴套设在传动轴423上,从而使得第二传动组件420能够稳定沿着传动轴423的轴向朝向或者背离第一传动组件410移动,保证第一传动组件410和第二传动组件420连接和分离的稳定性。
在一些实施例中,顶推套431的移动方向沿着第一方向,推杆432的顶推方向可沿着第一方向。
在一些实施例中,由于整体厚度空间较小,厚度方向的形成也相对较小,沿第一方向的直接顶推需要顶推结构的规格设置得很小,这无疑极大地加大了成型和装配难度。因此,可设置变向顶推的结构;可在顶推套431上设置与第一方向呈非平行状态的第一顶推面4311,从而能够通过顶推第一顶推面4311实现沿顶推方向的顶推操作,通过推杆432顶推第一顶推面4311将顶推套431推向第一传动组件410。
在一些实施例中,为了优化顶推操作的效率,可将第一顶推面4311与第一方向的夹角设置在30度~60度范围内,例如30度、45度或者60度等。
在一些实施例中,可将推杆432的顶推方向与第一方向的夹角按照90度控制,尽量缩小推杆432与第二传动组件420的配合布置所需要的布置空间,降低装置整体体积规模。
在一些实施例中,为了提升变向顶推的稳定性,可在推杆432上设置与第一顶推面4311相接触的第二顶推面4321,通过面面接触顶推错动的方式提升第一顶推面4311的受力均匀性,保证顶推套431的移动姿态的稳定性。
在一些实施例中,为了平衡顶推套431的受力,可将第一顶推面4311的数量设置成两个,相应的推杆432也设置有两个推臂4323,对应顶推两个第一顶推面4311;从而通过两点施力的方式保证顶推套431的受力均匀性。并可将两个推臂4323连接在同一个连接部4324上,实现同步动作且保证施力的大小一致,保证顶推套431受力均匀。相应地,两个推臂4323上分别设置有第二顶推面4321。
在一些实施例中,可将两个第一顶推面4311设置于顶推套431的相背两侧,两个推臂4323并列设置,第二顶推面4321设置在推臂4323上的远离连接部4324的端部,从 而通过顶推连接部4324即可实现顶推操作。
在一些实施例中,可根据顶推套431的规格情况,将第一顶推面4311、第二顶推面4321以及推臂4323的数量设置成两个以上。
在一些实施例中,为了限制顶推套431的转动,可在顶推套431上开设第一顶推槽4312,通过将推杆432嵌设到顶推槽4312内,将推杆432与顶推套432连接为一体,限制周向相对转动,保证顶推操作的可靠性。
在一些实施例中,可将第一顶推槽4312设置成两个,将推杆432设置成两个并列设置的推臂4323,并由连接部4324连接两个推臂4323。两个第一顶推槽4312设置于顶推套431的相背两侧,从而稳定的两点限位,保证顶推套431的受力稳定性。相适应的,在两个第一顶推槽4312的槽壁上分别设置第一顶推面4311。
在一些实施例中,可在两个推臂4323上远离连接部4324的端部分别设置有第二顶推面4321,两个第二顶推面4321分别与两个第一顶推面4311接触。
为了限制顶推套431的径向偏移,可在两个推臂4323上分别设置限位挡板4322,并具体将限位挡板4322设置在推臂4323的远离另一个推臂的一侧上,从而使得两个限位挡板4322挡设于顶推套的相背两侧。
为了实施推杆432的顶推操作,可在推杆432上连接直线驱动器433,沿第二方向顶推推杆432或者复位,从而通过直线驱动器433推动所述的顶推套431沿第二方向移动,实现第一传动组件410和第二传动组件420连接,建立开关门装置的力矩传递结构。在直线驱动器433复位时,推杆432释放顶推套431,断开第一传动组件410和第二传动组件420的连接,断开开关门装置的力矩传递结构。
在一些实施例中,直线驱动器433可采用电磁推杆,滚珠丝杆等直线移动组件。
在一些实施例中,驱动器110设置成减速电机,或者配置有减速齿轮箱的电机,从而能够合理控制输出扭矩和转速。
在执行离合控制时,通过直线驱动器433动作,推动推杆432朝向顶推套431移动,推杆432头端开设的第二顶推面4321顶推第一顶推面4311,实现顶推套431向上错动,使得顶推套431朝向第一传动组件410移动,同时带动第二传动组件420的第一传动件421朝第一传动组件410移动,直至第一传动件421的连接端4211嵌入第一传动件410的卡槽411内,建立周向传动连接关系,此时,直线驱动器433停留在当前位置,通过推杆432于底部支撑顶推套431,从而保持传动连接状态;驱动器110转动带动第二传动件422转动,继而带动第一传动件421、第一传动组件410以及联动齿轮120转动,实现开关门驱动。当需要断开连接时,直线驱动器433复位,顶推套431在自重作用下自然下落,连接端4211逐步脱离卡槽411,直至断开第一传动件421与第一传动组件410的连接,从而断开联动齿轮120与驱动器110之间的连接。在此过程中,在第一传动件421可相对于第二传动件422轴向滑动,实现上下位置的变化,通过二者内部的卡块4222和轴向通槽4217的卡嵌作用实现周向传动。值得说明的是,直线驱动器433的动作时机并不必然早于驱动器110的动作时间,也就是说二者不存在必然的延后顺序。
下面将分别介绍转门机构200和顶门机构300。
参见图10,在一些实施例中,可在门体920上设置铰接座230,与转门件220的第一端221铰接。为了保证铰接可靠性和受力均匀性,可将铰接座230设置成U型双臂铰接座,将转门件第一端221嵌入其内并通过铰轴固定。
在一些实施例中,带动件210和转门件220可设置成板状,从而再叠加状态下,能够极大地缩小安装高度。
参见图14,在一些实施例中,还可在带动件210和转门件220的枢接部分别设置成厚度缩减的形态,从而在枢转叠加状态下的整体厚度,缩小装配高度。还可将带动件210和转门件220的中的,布置在下方板状件上可转动地设置枢转轴214,承载居上的板状件,形成稳定可靠的枢接结构。在其他实施例中,可将带动件210和转门件220中的一个的端部设置成U形枢接座,另一个的端部嵌于其内并通过枢转轴214固定。
在一些实施例中,带动件210和转门件220可设置成杆状,兼顾小规格和高强度的转门结构。
在一些实施例中,联动齿轮120作为直接驱动带动件210和顶门机构300的元件,其驱动方式应当同时满足可偏转的带动件210和顶门机构300的动作模式。
在一些实施例中,顶门机构300作为初步顶开门体920到预设角度的执行机构,其可在驱动机构100的带动下,通过逐步蓄力的方式实现开门操作。下面将具体说明顶门机构300的结构。
参见图1和图12,在一些实施例中,顶门机构300包括联动件310以及顶门件320,联动件310一端连接驱动机构100,用于获取驱动力,联动件310可在驱动机构100的带动下动作,顶门件320另一端用于顶推门体920转动,顶门件320与联动件310相连,从而在联动件310的带动下实施顶门操作以及复位。
在一些实施例中,联动件310的一端转动地设置在底座600上,从而可在驱动机构100的驱动下绕一转轴偏转;顶门件320连接到联动件310上,从而可跟随联动件310在一弧形轨迹上移动,在抵触门体920后持续顶推门体920。通过联动件310的偏转结构能够在保证顶推效果的同时,一定程度上降低对顶门机构300正面压力,从而保证结构稳定性和使用寿命,提升顶门操作的可靠性。
在一些实施例中,为了进一步提升顶门操作的效率,可将顶门件320转动地连接在联动件310上,从而顶门件320能够相对于联动件310偏转,调整顶门件320的姿态,能够根据安装工况,适应性调整顶门件320的指向,从而能够正对门体920,保证高效率顶推。另一方面,顶门机构300能够适应不同安装工况的需求,灵活调整联动件310和顶门件320的配合状态,保证高效率的顶推性能。
在一些实施例中,顶门件320可转动地连接在联动件310的中部,为顶门件320留出足够的偏转空间,避免干涉其他结构。
为了保证高顶门效率,可将顶门件320的顶推方向大致设置成垂直于闭合的门体920的方向。由于顶门件320跟随联动件310转动,导致顶推方向也会出现一定幅度的偏转,为了实现顶门件320尽可能垂直于门体920稳定施加顶推力,可在顶门件320上开设腰型孔322,在联动件310上设置销轴360,通过将销轴360活动嵌设在腰型孔322内实 现顶门件320相对于联动件310偏转;同时还能够通过腰型孔322的长度方向空间给销轴360留出滑动空间,从而使得顶门件320能够沿腰型孔322的长度方向产生相对滑动,而不必跟随联动件310移动,从而维持顶门件320顶推方向的稳定。腰型孔322的长度可根据顶门行程的大小匹配设计,例如顶门行程越长腰型孔322的长度也相应越长。
在一些实施例中,为了以较小的开孔规格,满足较大顶推力以及顶推行程的需求,腰型孔322的长度方向可沿垂直于顶门件320的顶推方向设置。在其他实施例中,腰型孔322的长度方向也可不必严格按照垂直于顶门件320的顶推方向设置,也可存在一定的夹角,满足销轴360的移动行程在垂直于顶门杆320的顶推方向有分量即可,从而保证顶推杆320的轴向顶推姿态稳定;例如,夹角可设置成30度、45度,60度。
在一些实施例中,为了保证顶门件320的受力平衡,可将联动件310设置在顶门件320的下方,一定程度上支撑顶门件320,使得销轴360在其轴向上稳定嵌于腰型孔322内,而不会产生脱离的风险,从而保证腰型孔322和销轴360的枢转功能和相对滑动功能的稳定性。
在一些实施例中,可将腰型孔322设置在联动件310上,将销轴360设置在顶门件320上。为了保证枢转功能和相对滑动功能的稳定性,还可将联动件310设置在顶门件320上方,在此不作限制。
在一些实施例中,为了降低整体安装高度,缩小设备规模和降低安装空间需求以及材料成本,可在保证联动件310的结构强度的情况下,在联动件310上开设减厚沉槽312,从而降低联动件310和顶门件320的叠加厚度。减厚沉槽312的宽度规格可设置成略大于顶门件320在腰型孔322内偏转的区域宽度,避免减厚沉槽312的侧壁阻挡联动件310和顶门件320的相对偏转。
参见图12和图19,在一些实施例中,受到销轴360与腰型孔322之间的摩擦力影响,在联动件310偏转过程中,顶门件320仍然会有沿垂直于顶推方向的移动趋势;为此,可在底座600上开设导向槽632,顶门件320可沿设定的顶门方向滑动地设置在导向槽632内,限制顶门件320沿垂直于顶推方向的位移,保证顶门操作的稳定性。为了强化导向限位效果,可将导向槽632沿垂直于顶推方向的宽度设置成略大于顶门件320的宽度,仅保留一定的滑动间隙即可。
在一些实施例中,为了保证顶门件320的顺畅滑动,可在导向槽632的槽面上设置自润滑材料层,也可将顶门件320的对应导向槽632的部分设置自润滑材料层,或者,导向槽632的槽面以及顶门件320的对应导向槽632的部分均设置自润滑材料层,或者直接由自润滑材料成型,进一步降低摩擦影响。
参见图12,在一些实施例中,考虑到装配精度和配合间隙的影响,可在顶门件320背离联动件310的一端上铰接顶推座330,从而在顶门件320抵触到门体920时,顶推座330会先和门体920抵触,并能够自适应偏转,使得顶推座330与门体920实现面面接触,保证接触面的大小和姿态的稳定,保证顶门施力方向和大小的稳定,并降低局部接触顶推造成的具备接触压强过大损伤门体或者顶门件320的风险。
在一些实施例中,为了提升各个方向的适应能力,顶推座330与顶门件320可采 用万向铰接结构实现铰接连接。
在一些实施例中,为了降低顶推座330和门体920之间的接触震动,以及顶推座330的磨损,可在顶推座330上设置减震垫340。减震垫340可采用具备低摩擦系数的材料。
在一些实施例中,联动件310的第二端设置有与驱动机构100啮合的第一齿部313,从而通过齿轮啮合传动的方式驱动联动件310转动,从而实现联动件310的转动幅度精确控制,进而提升顶门机构300的顶推行程的控制精度。
在一些实施例中,考虑到顶门操作中,顶门开度多基于突破门体920与箱体910的吸附力和转门阻力的所需要的角度进行设置,门体920相对于箱体910的偏转角度可设置为3度左右,相应的顶推行程也相应较小,联动件310的偏转角度也可设置在较小水平。通常可根据配合状态将偏转的预设角度对应标定联动件310在底座600上的布置位置,形成联动件310对应在底座600上预设角度或者预设位置。
参见图12,在一些实施例中,为保证联动件310转角度的控制精度,可在底座600与联动件310之间连接弹性限位件370,始终将联动件310向预设位置牵引。能够保证控制精度的同时,还能够保证其与驱动机构100的啮合连接的对位精度和稳定性。
在一些实施例中,弹性限位件370可采用拉紧弹簧,其两端分别与联动件310和底座600相连,通过弹性伸长形变施加稳定弹性拉紧力。能够基于拉紧弹簧的自适应形变适应联动件310的偏转过程,并保证弹性拉紧效果的稳定性。在其他实施例中,弹性限位件370也可采用簧片等其他形式的弹性件。
参见图12、图14和图19,在一些实施例中,可在联动件310上设置第三固定座314,在底座600上设置第四固定座635,分别对应固定拉紧弹簧的两端,提升拉紧弹簧在偏转和形变作用下的稳定性。
在一些实施例中,还可在底座600上设置第一止挡件630,并将其布置在联动件310的预设偏转行程的端点处,当顶门机构300相对于底座600偏转到预设角度时与第一止挡件630抵触,从而限制联动件310的过度偏转,限制顶门机构300的整体进一步偏转;同时,还能够保证第一齿部313与驱动机构100稳定建立啮合连接。
参见图19,在一些实施例中,联动件310在驱动机构100的带动下,会进行顶门偏转和复位偏转,因此会相对于底座600产生两个相反方向的偏转,也就有两个偏转极限位,为了保证联动件310的位置控制精度,可在第一止挡件630上分别设置第一止挡面633和第二止挡面634,且分别对应布置在联动件310的预设偏转行程的两端点处,实现双向限位。其中,第一止挡面633和第二止挡面634可设置成与联动件310的外型面匹配的型面,提升接触限位的可靠性。
在一些实施例中,第一止挡件630可以是安装在底座600上的独立结构件,其高度略高于联动件310的布置高度,从而实现止挡功能。在其他实施例中,第一止挡件630还可以直接成型在底座600上,在底座600上成型具备止挡型面或者止挡部的集成结构。
在一些实施例中,可将第一止挡件630与弹性限位件370配合设置,即可通过布置弹性限位件370的安装位置,将联动件310向第一止挡件630弹性拉紧或者弹性压紧。
参见图12和图19,在一些实施例中,可在第一止挡件630上开设弹性件容置槽631,将弹性限位件370的第一端连接在弹性容置槽631内,不仅可实现弹性限位件370在底座600上的装配,还通过槽体结构保护弹性限位件370,避免剐蹭碰撞影响其形变状态,从而保证联动件310的到位控制可靠性和精度。
参见图12、图14和图19,在一些实施例中,第四固定座314可设置在第一齿部313和销轴360之间的联动件310上,即位于联动件310的受力点和施力点之间,一定程度上提升弹性限位作用效果,提升联动件310抵抗震动和外部干涉的性能。
在一些实施例中,为了适应联动件310的偏转动作,弹性限位件370的第二端也会产生一定程度的偏转,使得弹性限位件370整体会以其第一端为圆心产生偏转,为了避免弹性容置槽631剐蹭顶抵影响其形变状态,可将弹性容置槽631的槽体形态设置成类扇形,留出足够的偏转空间。
在一些实施例中,可将联动件310设置成板件,其板厚方向垂直于偏转方向设置,从而能够保证顶门操作工况下的结构强度,还可降低联动件310的整体装配厚度,降低安装高度需求。还可将顶门件320也设置成板件,其板厚方向垂直于偏转和顶推方向设置,可整体降低装配高度。在其他实施例中,联动件310和顶门件320也可以设置成杆件。
参见图14和图15,在一些实施例中,可将第一齿部313设置在联动件310的板件主体的第一端,联动件310的板件主体的第二端开设联动件枢转孔311,在底座600上设置联动件枢转轴350,联动件枢转轴350转动地嵌设在联动件枢转孔311内,从而使得联动件310可相对于底座600转动,在满足其联动功能的情况下,降低其整体体积。在其他实施例中,腰型孔322也可设置在顶门件320的板件主体的第一端,在满足顶门功能需求的同时,降低其长度和宽度,降低其整体体积。
在一些实施例中,为了提升联动件310和顶门件320的结构强度,可在其板件主体上设置加强筋。
在装配到具备箱体910和铰接在其上的门体920的电器设备上时,可将底座600固定在箱体910上,并将顶门件320的顶门方向正对门体920。在执行开门操作时,通过驱动机构100驱动联动件310相对于底座600正向偏转,带动顶门件320沿导向槽632滑动,直至接触到门体920且顶推力逐步增加,直至突破门体920与箱体910之间的吸附力和其他转动阻力,即可顶开门体920;在执行关门操作时,驱动机构100驱动联动件310相对于底座600反向偏转,带动顶门件320沿导向槽632反向滑动,直至复位。
参见图13,在一些实施例中,顶门机构300还可设置成一体的顶门型件380,且顶门型件380可通过类似联动件枢转轴350的转轴转动地设置在底座600上。可将顶门型件380进行功能区域划分,可设置用于啮合连接驱动机构100的第四齿部381,在驱动机构100启动时,驱动顶门型件380转动;并可在顶门型件380上设置顶门部382,在驱动机构100的驱动下转动时,顶推门体920,直至将门体920顶开设定开度。
在一些实施例中,顶门型件380为类扇形结构件,顶门部382为类扇形结构件的一侧端角,当顶门型件380转动时,沿弧形轨迹顶推门体920。在其他实施例中,可将顶门型件380设置成凸轮结构,并将第一齿部381和顶门部382设置到凸轮的轮缘上。凸轮 相对底座600转动,并在驱动机构100的带动下转动,沿弧形轨迹平滑顶推门体920,降低冲击震动剧烈程度。
在一些实施例中,为了提升结构强度,可在类扇形结构件上设置加强筋383。
参见图20、图21和图22,在一些实施例中,底座600设置成由两块相配合的独立壳体扣合拼装而成,相应可配置紧固螺钉等紧固件锁紧。可在对应顶门件320或顶门型件380、转门件220以及带动件210动作的区域开设窗口,便于实施顶门件320或顶门型件380、转门件220以及带动件210伸出,保证开关门操作的顺畅执行,同时也能够兼顾有序收纳,保护其内部功能结构。
在一些实施例中,可对应于同轴转轴211和联动件枢转轴350的位置,设置转轴强化固定结构,保证枢转结构的可靠性。
在一些实施例中,在底座600上设置同轴转轴座650,用于转动固定同轴转轴211,提升结构稳定性,充分提升抗冲击性能,保证转门机构200和联动齿轮20的稳定可靠的同轴枢接在底座600上。在底座600上设置有用于固定驱动器110的驱动电机固定槽610。
参见图26和图27,本实施还提供一种冰箱,包括箱体910和门体920,且门体910为转动设置在箱体910上。并在箱体910和门体920之间连接开关门装置,用于顶推或者门体920实现门体920相对于箱体910偏转,实现开关门操作。
在一些实施例中,开关门装置设置有底座600固定在箱体910上,并将顶门件320或者顶门型件380指向或者顶抵在门体920上,转门件220通过铰接座230铰接在门体920上。在其他实施例中,底座可以是成型在箱体910顶部的集成型面结构,承担底座的功能。再另一些实施例中,底座600也可以设置在门体920上,顶门件320或者顶门型件380指向或者顶抵在箱体910上,转门件220通过铰接座230铰接在箱体910上。在一些实施例中,冰箱设置有多个门体920,可对应每个门体920设置独立的开关门装置,实现多门体冰箱的自动开关门功能化实现。
参见图28和图29,在执行开门操作时,联动齿轮120正向转动,带动顶门机构300直接顶推门体920,当联动齿轮120转动一定角度后,继续的顶推力达到突破开门阻力的临界值,顶开门体并维持在一定的角度,并随着联动齿轮120继续正转时,第一齿部313与第二齿部1221断开啮合状态,联动杆310在弹性限位件370作用下拉紧在第一止挡件630上;过程中,转门机构200的带动件210自第一顶推部1231向第二顶推部1232靠近,直至带动件210顶抵在第二顶推部1232时即可跟随联动齿轮继续正转,顶推门体920直至达到设定的极限位置,实现开门转门操作。
参见图23、图24、图25和图30,在执行关门操作时,联动齿轮120反转,当第一顶推部1231顶抵到带动件210后继续反转,并顶推带动件210反转,拉动转门件320和门体920向箱体910转动,直至闭合箱体,实现关门操作;过程中,联动齿轮120转动到一定角度位置,通过第二齿部1221与第一齿部313啮合连接,顶推联动件310反转,直至到达初始位置。
本实施例提供一种开关门控制方法,用于对配置有开关门装置的电器设备的开关门操作的控制。电器设备为具备箱体910和门体920,且门体910为转动设置在箱体910 上,通过将开关门装置设置在箱体910上,顶推以及转动门体920实现开门或者转动门体920实现关门。开关门装置为设置在底座600上且可相对于底座600转动的顶门机构300和转门机构200,通过驱动机构100的联动齿轮120驱动顶门机构300和转门机构200实现机械顶门和转门操作,执行开关门操作。
参见图11,在一些实施例中,为了保证转门机构200的转门效率和结构的稳定性,降低带动件210和转门件220的相对偏转状态和伸展长度对门体开度和转门速度的,可结合电器设备的门体920的转动中心点B以及底座600的布置位置对转门机构200及其与门体920的铰接点C进行规划布置。将转门件220一端与门体920的铰接点C,带动件210与转门件220的一端的铰接点A,带动件210的另一端转动地设置于底座600的铰接点D进行分布状态设计,即,铰接点A与转动中心B分别位于铰接点C与铰接点D的连线两侧,形成一个凸四边形,避免转动过程中带动件210和转门件220形成超过180度的偏转量,而导致的转门件220不受力的极端状态,以及无法转动门体920的问题,同时也限缩了门体920的开度范围。
在一些实施例中,为了最大限度的发挥门体920和箱体910结构本身的可开启角度,而不会过度受限于转门机构200,可按照铰接点A、铰接点C、转动中心B和铰接点D依次连接围成的四边行为平行四边形的原则,设置转门件220一端与门体920的铰接点C的位置,带动件210的另一端与底座600的铰接点D的位置,以及带动件210和转门件220的两铰接点的长度;在此状态下,排除结构宽度厚度以及转轴合页等结构件的原因,门体920的开度能够趋近于180度。当然,冰箱门体的920的并非越大越好,而是根据其安装工况,使用需求,便捷性等多重因素确定的。在其他实施例中,通过上述布置方式,能够稳定可靠的实现门体开度在130度。
参见图2、图3、图4和图5,在一些实施例中,在驱动器110和联动齿轮120之间设置离合装置功能结构,从而控制联动齿轮120与驱动器110之间的驱动力传递,实现开关门操作的中断和启停控制。离合功能结构设置有具备分离状态和连接状态的相配合的第一传动组件410和第二传动组件420,还设置有用于建立第一传动组件410和第二传动组件420的连接关系和中断连接关系的离合顶推组件430。其中,第二传动组件420与驱动器110相连,以获取驱动力;第一传动组件410连接联动齿轮120,以向驱动联动120传递驱动力。通过离合顶推组件430推动第二传动组件420与第一传动组件410相互靠近,建立配合连接状态,从而将驱动器110的驱动力依次通过第二传动组件420和第一传动组件410传递给林动齿轮120,驱动联动齿轮120转动;还可通过离合顶推组件430推动第二传动组件420与第一传动组件410相互远离,解除配合连接状态,从而切断联动齿轮120获得驱动力的路径,停止联动齿轮的转动。因此,可通过停止转动指令控制离合顶推组件430的动作,实现联动齿轮120的控制,从而满足一些紧急工况或者偶然性停转门体920的使用需求。
在一些实施例中,冰箱门体920的到位信息可通过配置用于检测联动齿轮120的转动角度值的角度采集单元500,并通过预先建立的联动齿轮120的转动角度值与门体920的到位信息的关联,从而可通过检测联动齿轮120的实时的角度信息,即转动角度值,间 接确定门体920的位置,并基于此实施驱动机构100的开关门控制,即驱动器110的启停控制,以及控制离合顶推组件430的动作,继而控制第二传动组件420与第一传动组件410的连接和分离。在其他实施例中,可具体通过离合顶推组件430控制第二传动组件420的移动,实现离合功能,而将第一传动组件410设置成相对底座600位置不变的结构。
在一些实施例中,还可通过实时监测联动齿轮120的转动角度信息,从而反馈控制离合装置400的动作,即控制离合顶推组件430推动第一传动组件410和第二传动组件420之间的分离和连接,从而实现转门过程的控制。
在一些实施例中,通过采集单元500实时监测联动齿轮120的转动的角度信息,并以此确定是否执行离合顶推组件430的顶推动作,以控制第一传动组件410和第二顶推组件420的分离和连接。
在一些实施例中,角度信息设置成表征联动齿轮120所转动的角度值,并比较其与预设角度值的大小。若联动齿轮120所转动的角度值小于预设角度值,则顶推离合组件430不动作,保持第一传动组件和第二传动组件420的连接状态;若联动齿轮120所转动的角度值大于等于预设角度值,则顶推离合组件430动作,推动第一传动组件410和第二传动组件420分离,切断连接状态。
在一些实施例中,预设角度值的大小根据开关门过程中的预设位置对应的转动角度值设置。预设角度值可以是对应最大开度的转动角度值,也可以是中间任意开度位置对应的转动角度值。从而在可在开门到位或者关门到位时,切断第一传动组件410和第二传动组件420的连接。
在一些实施例中,可将角度信息设置成矢量角度值,即能够对应联动齿轮120的正反转,输出正向转动角度值和反向转动角度值,相应的,预设角度值也设置成矢量阈值。当联动齿轮120的正向转动角度或者反向转动角度达到其对应方向的预设角度值,离合顶推组件430分离第一传动组件410和第二传动组件420。在其他实施例中,还可一并停止驱动器110的动作。
在一些实施例中,角度信息还可设置成表征联动齿轮120的转动角加速度值,并基于角加速度值控制顶推组件430的动作与否,以分离还是保持第一传动组件410和第二传动组件420的连接状态。
在一些实施例中,通过比较角速度值与预设加速度值的大小控制离合顶推组件430的动作。
在一些实施例中,为了避免转门过快导致过度冲击偏转区域内的人或物,造成内储物资震动跌落以及碰撞安全风险,可在角加速度大于等于预设角加速度时,驱动离合顶推组件430动作,分离第一传动组件410和第二传动组件420。此时对应的角加速度值为上角加速度限值。
在一些实施例中,考虑到出现门体顶抵在人或物上,自身转动结构卡死,或者开关门机构故障等情况下,出现角加速度过小时,即小于角加速度下限值,也可以实施保护性操作,即通过驱动离合顶推组件430动作,分离第一传动组件410和第二传动组件420避免损伤开关门装置,自身转动结构等。
在一些实施例中,驱动器110为电机。在其他实施例中,还可配置控制器,接收控制指令并控制电机和离合顶推组件430的动作。
在一些实施例中,开门指令、关门指令以及停止转动指令可通过主动输入设备输入,通过操作主动输入设备施加设定的触发信号,控制开关门装置的驱动机构100执行相对应的动作,进而驱动顶门机构300和转门机构200动作,实施开门操作。在其他实施例中,主动输入设备可设置成语音输入终端,红外感应终端,触控终端等。在其他实施例中,还可以是设置在门体920或者箱体910上的压力传感器等感应操作压力的传感器元件。
本公开内容还提供一种采用上述控制方法的冰箱,该冰箱设置有控制器,并将上述开关门装置与控制器相连,并通过控制器实施开关门控制。当然,还可将开关门装置集成统一在冰箱的控制器***中。
本公开内容所提供的一种电器设备、开关门装置及其离合器的控制方法,通过驱动机构驱动的顶门机构和转门机构分别实现自动顶门操作和转门操作,提升开门操作的便捷性和安全性。可通过顶门机构顶推门体,蓄力突破开门阻力将门体顶开到设定角度,从而大幅降低后续转门机构转门的阻力,提升自动开门速度。并进一步,设置可分离连接的第一传动组件和第二传动组件,并在离合顶推组件的作用下实现主动离合,且第二传动组件连接驱动器,第一传动组件连接顶门机构与转门机构,从而能够实现驱动机构与执行机构之间的离合,有效避免自动开关门和手动开关门操作的干涉;并能够通过灵活可控制离合功能,实现驱动器与顶门机构和转门机构的保护。并通过设置角度监测单元实时监测联动齿轮的转动角度,从而作为判断工况的依据以及反馈控制离合顶推组件和驱动机构的动作的依据,从而极大地提升了开关门的可靠性。
尽管已描述了本申请的优选实施例,但本领域内的普通技术人员一旦得知了基本创造性概念,则可对这些实施例作出另外的变更和修改。所以,所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然,本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样,倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内,则本申请也意图包含这些改动和变型在内。
