Description

缓冲结构和制冷设备
本申请要求于2020年06月18日提交中国国家知识产权局、申请号为“202010558634.4”、申请名称为“缓冲结构和制冷设备”和申请号为“202021136132.4”、申请名称为“缓冲结构和制冷设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及缓冲件技术领域，具体而言，涉及一种缓冲结构和一种制冷设备。
背景技术
目前，大部分用户在日常存储食材时都通过冰箱实现，而冰箱在使用过程中，通常由于需要保证内部的恒温而控制压缩机运行实现制冷，然而在压缩机运行过程中，会发生振动，由于压缩机固定在冰箱的壳体上，在发生振动时会传递至冰箱上，从而使得冰箱也随之发生振动产生噪音，现有技术中采用脚垫实现缓冲，然而虽然脚垫材质较为柔软可吸收一部分振动，但压缩机的振动仍能通过脚垫传至冰箱的壳体上，减震效果并不尽如人意。
发明内容
本申请旨在至少解决现有技术或相关技术中存在的技术问题之一。
有鉴于此，本申请的一个目的在于提供一种缓冲结构。
本申请的另一个目的在于提供一种制冷设备。
为了实现上述至少一个目的，根据本申请第一方面的技术方案，提出了一种缓冲结构，包括：减振本体，减振本体的一端形成有卡接部，且减振本体内设有贯穿两个端面的缓冲孔；至少一个横向减振孔，设于减振本体上，且每个横向减振孔沿缓冲孔的径向设于缓冲孔的一侧。
根据本申请提出的缓冲结构，包括减振本体和横向减振孔，减振本体 上设有卡接部，其形成于减振本体的一端，卡接部可用于与待缓冲对象相连，使得待缓冲对象在连接至卡接部时，待缓冲对象内部的振动可传递至减振本体，此外，由于在减振本体上还设有一个或多个横向减振孔，在待缓冲对象发生振动时，通过横向减振孔可将垂直于横向减振孔的轴线方向的振动进行削弱，从而降低待缓冲对象对连接件所连设备的横向振动传递，提高横向减振性能。
需要说明的，由于横向减振孔设于缓冲孔的径向一侧，一般地，缓冲孔内侧需要与连接件相配合，故而一个或多个横向减振孔均设于缓冲孔的径向外侧。
其中，减振本体的材料可以为具有一定弹性的材质，例如橡胶，更进一步地，可选用具有耐磨耐油耐腐蚀的橡胶材料制成减振本体。
其中，横向减振孔的数量可以为一个，也可以为多个，可根据减振本体的径向尺寸或是缓冲孔的具体缓冲需求灵活设置。
当然，横向减振孔的设置密度也可以根据具体的缓冲结构所设置的位置调整，例如，缓冲结构设于压缩机底部的前侧，则可将缓冲结构后侧的区域设置较多数量的横向减振孔，缓冲结构前侧的区域设置较少数量，甚至不设置横向减振孔。
在上述技术方案中，连接筋，设于横向减振孔内，连接筋将横向减振孔内分隔形成至少一个减振腔。
在该技术方案中，通过在横向减振孔内设置用于分隔空间的连接筋，可将横向减振孔的内部空间分隔形成一个或多个减振腔，一方面通过设置连接筋可增强横向减振孔的轴向抗压强度，另一方面，由于分隔形成一个或多个减振腔，可根据实际不同的减振需求灵活调整，以提高减振效果的针对性。
其中，连接筋可沿横向减振孔的轴向设置，也可以沿横向减振孔的径向设置。
在上述技术方案中，减振本体的轴线与缓冲孔的轴线相重合。
在该技术方案中，通过限定减振本体和缓冲孔的轴线相重合，即缓冲孔中心设置，从而使得卡接部也设于中心处，在连接时可增加与待减振对 象的支撑效果，提高稳定性，同时，由于缓冲孔居中设置，也便于连接件的连接。
在上述技术方案中，横向减振孔的数量为多个，多个横向减振孔绕缓冲孔的轴线均匀设置。
在该技术方案中，在设置多个横向减振孔时，可将多个横向减振孔均匀绕设于缓冲孔的四周，从而提高缓冲结构整体的稳定性。
在上述技术方案中，卡接部的一端设有导向倒角，另一端设有沿缓冲孔的径向内凹的凹槽。
在该技术方案中，通过在卡接部的两端分别设置导向倒角和凹槽，便于待减振对象与缓冲结构的连接，具体地，待减振对象通过导向倒角向缓冲结构移动，导向倒角在移动过程中对待减振对象起到导向的作用，可使得待减振对象在安装过程中发生偏移时，通过导向倒角引导待减振对象移动至配合位置后，沿轴向继续移动直至移动至凹槽内，以实现卡接部与待减振对象的卡接配合。
在上述技术方案中，横向减振孔为通孔或盲孔。
在该技术方案中，横向减振孔可以为两端均贯穿的通孔，或仅一端贯穿的盲孔，可根据实际使用需求灵活设置，在设置为通孔形式时，横向减振孔将减振本体的两端贯通，使得横向振幅在经过横向减振孔时产生削弱，以实现减振的效果。
进一步地，横向减振孔可以为直孔，即横向减振孔的轴线与缓冲孔的轴线相互平行。
在上述技术方案中，缓冲孔内形成呈阶梯状的第一孔和第二孔，第一孔设于减振本体靠近卡接部的一侧，其中，第一孔的内径大于第二孔的内径。
在该技术方案中，缓冲孔具体包括呈阶梯状的第一孔和第二孔，通过限定内径较大的第一控设于卡接部的一侧，从而在连接件由第二孔伸入缓冲孔时，若连接件发生一定的弯折，或者在连接件在连接时与缓冲孔的轴线发生偏移时，可通过第一孔宽于第二孔的部分实现一定程度的避让，以减少连接孔直接与第一孔的内壁相接触，同样也缩短卡接部与连接件之间 的传递路径，增强减振效果。
在上述技术方案中，至少部分缓冲孔的内径沿由减振本体远离卡接部的一端至卡接部的方向逐渐增大。
在该技术方案中，通过限定沿远离卡接部的一端至卡接部的方向，缓冲孔设于卡接部的部分的内径逐渐增大，从而使得卡接部内的缓冲孔呈扩孔状，在连接件伸入缓冲孔时，如果发生一定的弯折，或者在连接件在连接时与缓冲孔的轴线发生偏移时，在卡接部的一侧的缓冲孔由于呈扩孔状，会尽量增大与轴线之间的距离，从而为连接件发生弯折或偏移时提供空间，以减少连接件直接与卡接部的内壁面相接触，降低减振效果。
需要说明的是，缓冲孔的内径沿轴向逐渐增大，可以呈线性均匀增大，当然，其变化率可以随距缓冲孔端面的距离逐渐变化，即呈曲线增大。
本申请第二方面技术方案提出了一种制冷设备，包括壳体，壳体内设有压缩机；以及上述第一方面技术方案中的缓冲结构，设于壳体内，其中，壳体的底板设有连接件，缓冲结构的缓冲孔套设于连接件外，且压缩机的底部配合件与缓冲结构的卡接部相配合。
通过本申请第二方面的制冷设备，包括内设有压缩机的壳体以及设于壳体内的缓冲结构，具体地，壳体的底板上设有连接件，在安装时，先将连接件穿过缓冲结构的缓冲孔，再将压缩机的底部配合件通过卡接部与缓冲结构的另一端相配合，直至卡入后实现连接。
需要说明的是，由于制冷设备包括上述第一方面技术方案中的任一缓冲结构，故而具有上述第一方面技术方案中的任一技术效果，在此不再赘述。
在上述技术方案中，连接件与缓冲孔的内壁存在间隙。
在该技术方案中，通过限制连接件和缓冲孔之间存在间隙，以减少压缩机在振动时通过缓冲结构将振动传递至连接件，从而使得连接件带动壳体发生振动，以降低由于振动而带来的噪音。
当然，可以理解，由于连接件和缓冲孔之间存在间隙，制冷设备运动过程中，可能随运行时间的累积，二者之间的间隙会越来越小，直至发生相抵。
在上述技术方案中，连接件的最大外径小于缓冲孔的最小内径。
在该技术方案中，通过限定连接件的最大外径小于缓冲孔的最小内径，可使得连接件沿轴向设于缓冲孔内时，可减少与缓冲孔内壁相接触的可能性，以降低壳体的振动。
本申请的附加方面和优点将在下面的描述部分中变得明显，或通过本申请的实践了解到。

具体实施方式
为了可以更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。

其中，缓冲孔124和横向减振孔14的孔内可以部分为直孔，也可以全部为直孔。
进一步地，在减振本体12竖直放置时，即缓冲孔124沿上下方向设置，连接件26由缓冲孔124下侧伸入，并向上延伸，而待缓冲对象则与缓冲孔124上侧的卡接部122相配合，从而尽可能地延长二者所接触的位置之间的距离。
在此基础上，可限定部分缓冲孔124的内径由下至上逐渐增大，呈扩孔状，会尽量增大缓冲孔124的内壁与轴线之间的距离，从而为连接件26发生弯折或偏移时提供空间，以减少连接件26直接与卡接部122的内壁面相接触，降低减振效果。
其中，扩孔状的缓冲孔124可以呈喇叭状，或倒锥状，即上大下小的趋势。
其中，减振本体12的材料为具有耐磨耐油耐腐蚀的橡胶。
更进一步地，在减振本体12上，横向减振孔14均设于缓冲孔124的外侧。
在一个具体的实施例中，横向减振孔14相对于缓冲孔124的具体设置位置，与缓冲结构1整体相对于待缓冲对象的位置相关，在将缓冲结构1设于待缓冲对象底部的前侧时，可将横向减振孔14设于待缓冲对象的后侧。
在另一个具体的实施例中，横向减振孔14设于待缓冲对象底部的左前方的角落上，此时则可将横向减振孔14设于待缓冲对象的右后方。
当然，还可以的，如图5所示，横向减振孔14在缓冲孔124上侧的密度大于缓冲孔124下侧的密度。

在实施例1的基础上，如图3所示，在一个或多个横向减振孔14内设有连接筋142。
在一个实施例中，连接筋142沿横向减振孔14的径向设置。
在另一个实施例中，一个横向减振孔14内设有两个连接筋，且两个连接筋呈交叉状设置，每个连接筋均与横向减振孔14的轴向呈锐角的角度。
实施例3
如图2所示，根据本申请的一个实施例提出了一种缓冲结构1，包括：包括一端设有卡接部122的减振本体12，卡接部122可用于与待缓冲对象相连，此外，在减振本体12内居中设有缓冲孔124，即减振本体12的轴线与缓冲孔124的轴线相重合，此外，在减振本体12内设有缓冲孔124以及一个或多个横向减振孔14，连接件26可通过缓冲孔124的一端伸入，并向卡接部122的方向延伸。
更进一步地，在卡接部122的轴向两端分别设置导向倒角1222和凹槽1224，在将待减振对象安装至缓冲结构1上时，待减振对象的底部开设有配合孔，将配合孔套在导向倒角1222外，并向下不断移动，由于缓冲结构1具有一定的弹性，卡接部122会不断的穿过配合孔，直至配合孔移动至凹槽1224处，以实现卡接。
在上述任一实施例的基础上，如图4所示，横向减振孔14的数量为多个，多个横向减振孔14绕缓冲孔124的轴线均匀设置。
进一步地，每个横向减振孔14可以为通孔，也可以为盲孔。
实施例4
如图2所示，根据本申请的一个实施例提出了一种缓冲结构1，包括：包括一端设有卡接部122的减振本体12，卡接部122可用于与待缓冲对象相连，此外，在减振本体12内居中设有缓冲孔124，即减振本体12的轴线与缓冲孔124的轴线相重合，此外，在减振本体12内设有缓冲孔124以及一个或多个横向减振孔14，缓冲孔124内形成有相连通的第一孔1242和第二孔1244，二者同轴设置，且第一孔1242设于第二孔1244的上方，连接件26可通过第二孔1244伸入缓冲孔124，并向第一孔1242的方向延 伸。
在使用过程中，若连接件26发生一定的弯折，或者在连接件26在连接时与缓冲孔124的轴线发生偏移时，可通过第一孔1242宽于第二孔1244的部分实现一定程度的避让，以减少连接孔直接与第一孔1242的内壁相接触，同样也缩短卡接部122与连接件26之间的传递路径，增强减振效果。
实施例5
如图6和图7所示，根据本申请的一个实施例提出了一种制冷设备2，包括壳体22，以及设于壳体22内的压缩机24，壳体22的底板221上设有连接件26，压缩机24底部设有底部配合件242，在将压缩机24固定在壳体22上时，可先将缓冲结构1套在连接件26上，此时，再将底部配合件242卡接至缓冲结构1的卡接部122上，以实现压缩机24的固定。
当然，为保证压缩机24的稳定，可在壳体22的底板221上设置多个连接件26，多个连接件26和多个缓冲结构1一同实现压缩机24的固定。
其中，连接件26可以呈柱状，在连接件26伸入缓冲孔124时，如果发生一定的弯折，或者在连接件26在连接时与缓冲孔124的轴线发生偏移时，可将缓冲孔124的上端设置呈扩孔状，会尽量增大与轴线之间的距离，从而为连接件26发生弯折或偏移时提供空间，以减少连接件26直接与卡接部122的内壁面相接触，降低减振效果。
在一个具体的实施例中，制冷设备2可以为冰箱或制冰机。
在另一个具体地实施例中，制冷设备2可以为移动空调、或分体式空调的室外机。
实施例6
根据本申请的一个具体实施例提出了一种可提高横向减振性能的压缩机24用脚垫(即缓冲结构1)，脚垫内部为台阶通孔结构(即缓冲孔124内形成第一孔1242和第二孔1244)，脚垫外部主体部分开设有若干镂空凹槽1224(即横向减振孔14)。压缩机24实际安装过程中，脚垫内孔(即缓冲孔124)与安装螺栓约束，脚垫外缘与冰箱底板221约束，主体部分开设的镂空凹槽1224结构可有效降低脚垫横向的刚度，从而提高脚垫横向减振性能。
进一步地，脚垫的材质选为橡胶。
进一步地，橡胶材料具有耐磨耐油耐腐蚀特性。
进一步地，脚垫内部为台阶通孔结构。
此外，脚垫内孔下端为限位凸台结构，即缓冲孔124的下端可设有沿径向向轴线方向凸出的凸筋。
其中，减振脚垫外部主体部分开设有多个镂空凹槽1224。
此外，还提供了一种压缩机24，使用上述脚垫，可使压缩机24在运行过程中的振动小且噪音低，大大提高往复式压缩机24的运行稳定性。
通过本申请提出的缓冲结构和制冷设备，可将垂直于横向减振孔的轴线方向的振动进行削弱，从而降低待缓冲对象对连接件所连设备的横向振动传递，提高横向减振性能。
