具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1所示，本发明的实施例中提供了一种洗衣机轴套，包括环形外壳1、可装配轴承的轴承安装室2、以及设置在环形外壳1和轴承安装室2之间的若干支撑体；支撑体沿轴承安装室2的径向延伸、两端分别与环形外壳1的内壁以及轴承安装室2的外壁连接。
本发明的实施例中，在洗衣机工作时，内筒轴的转动对轴承安装室2产生周向压力，由 于在环形外壳1与轴承安装室2之间设有若干支撑体，支撑体支撑在环形外壳1与轴承安装室2之间，支撑体能够将上述压力分散，使得环形外壳1受力比较分散，从而使得外筒底受力比较分散，使得外筒不易变形损坏，并且，由于轮辐式轴套本体嵌入洗衣机外筒底设置，环形外壳1以及支撑体与外筒底均接触连接，使得该轴套与外筒底的连接除了环形外壳1的周向连接，还有支撑体与外筒底的斜向连接，增多了该轴套与外筒底之间连接维度，使得轴套被固定的好，从而在外筒底上不易松动，稳定性好。
优选地，若干支撑体均匀设置，能够将压力分散的比较均匀，使得环形外壳1受力比较分散，且均匀，使得外筒更加不易变形损坏；
该轴套镶嵌在外筒底上，轴套镶嵌在外筒底上的方式如下：洗衣机轴套采用铸铁或者铝合金材质，外筒底采用塑料材质，洗衣机轴套与外筒底本体10采用注塑的方式一体成型，注塑采用的高分子热塑材料将轴套包裹固定在外筒底上，以提高实现外筒底与轴套之间的紧固性，有效降低内筒高速旋转震动产生的噪音。
支撑体分别与环形外壳1的内壁以及轴承安装室2的外壁连接的方式包括：支撑体分别与环形外壳1的内壁以及轴承安装室2的外壁圆滑过渡，避免应力集中，减少洗衣机轴套损坏的频率。
如图1所示，本发明的实施例中，支撑体上设有与电机定子安装孔62适配的安装部。
在现有技术中，电机固定的方式包括以下方式：方式一：采用螺丝钉等紧固部件将电机定子固定连接在外筒底，外筒采用塑料材质，固定在外筒上的螺丝钉等一般为金属件，两种材料的部件之间的紧固作用有限，当长时间使用后，外筒后板材料易发生脆化，从而易导致电机固定不牢、甚至脱松，从而引起内筒旋转时的机械故障；方式二：在外筒底上增设固定电机的加强板，其中，多采用螺丝钉等紧固部件将加强板固定连接在外筒底，螺丝钉长时间使用后易松动，那么则会导致加强板的作用失效；
本发明的实施例中，针对方式一而言，通过电机定子安装孔62与安装部6的配合将电机定子连接固定在支撑体上，由于支撑体采用铸铁或者铝合金材质，能够使得螺丝钉等金属件与支撑体之间的紧固作用比较强，从而将电机12固定的比较牢固，不易脱松；针对方式二而言，将电机定子直接固定在支撑体上，能够省去加强板，降低制造成本。
如图1所示，本发明的实施例中提供了一种洗衣机外筒底，包括外筒底本体10以及镶嵌在外筒底本体10内部的轴套；轴套包括可装配轴承的轴承安装室2，自轴承安装室的外壁向外径向延伸有支撑体。
在现有技术中，现有外筒底的轴套多为具有轴承安装室的圆柱形设计，轴承装配在轴承 安装室内，内筒轴贯穿轴承安装室与电机的转子连接，现有的轴套多采用铸铁或者铝合金材质，轴套嵌入外筒底，且通过注塑工艺与外筒底一体成型，在注塑工艺中，注塑采用的高分子热塑材料将轴套包裹固定在外筒底上，由于轴套多为圆柱形设计，使得外筒底受到的内筒轴应力比较集中，从而使得外筒底易变形损坏，导致外筒底强度较差。
在本发明的实施例中，在洗衣机工作时，内筒轴的转动对轴承安装室以及外筒底产生轴向应力，洗衣机外筒底的轴套包括轴承安装室2以及至少一个支撑体，支撑体设于轴承安装室2的外壁，通过在轴承安装室2的外壁设支撑体，支撑体能够将内筒轴应力分散于外筒底，减小外筒底的变形，从而提升外筒底强度。
需要说明的是，支撑体与轴承安装室2的外壁连接的方式包括：支撑体与轴承安装室2的外壁圆滑过渡，避免应力集中，减少洗衣机轴套损坏的频率。
以洗衣机轴套为中心，外筒底本体10为向外发射的弧形板，且弧形板背向外筒的内部凸出以增大外筒的体积。
在本发明的实施例中，轴套包括若干个支撑体；
各支撑体沿轴承安装室2的周向间隔排布于轴承安装室2的外壁，且沿轴承安装室2的径向延伸；
优选的，轴承安装室2与外筒底本体10同轴设置。
本发明的实施例中，在洗衣机工作时，内筒轴的转动对轴承安装室2以及外筒底产生轴向应力，由于沿轴承安装室2的周向，轴承安装室2外壁设有若干支撑体，支撑体能够将上述轴向应力分散于外筒底各处，使得外筒底受力比较均匀，使得外筒底不易变形损坏，能够提升外筒底的强度；
此外，由于轴套镶嵌入洗衣机外筒底设置，轴承安装室2以及支撑体与外筒底均接触连接，使得该轴套与外筒底的连接除了轴承安装室2的周向连接，还有支撑体与外筒底的斜向连接，增加了轴套与外筒底之间连接维度，使得轴套被固定的好，从而在外筒底上不易松动，稳定性好。
优选地，若干支撑体均匀设置，增加了轴向应力分散的均匀性，进一步提升外筒底强度。
本发明的实施例中，轴套还包括环形外壳；
支撑体沿轴承安装室2的径向延伸至与环形外壳1的内壁连接；
优选的，环形外壳沿外筒底外周延伸一圈。
本发明的实施例中，支撑体的两端分别与轴承安装室2以及环形外壳1连接，环形外壳1相对若干个支撑体而言增大了支撑面积，能够进一步增加轴向应力分散的均匀性，进一步 提升外筒底的强度。
如图1所示，本发明的实施例中，辅助支撑体1的外壁设有环形加强筋。
环形加强筋9设于轮辋式外壳1的外壁，能够增加轮辋式外壳1的强度，使得该轴套的强度增加，增强抵抗外力的能力。
如图1以及图2所示，本发明的实施例中，安装部6包括安装部本体61，安装部本体61上开设有与电机定子安装孔适配的安装孔62，其中，安装孔62的轴心线与轴承安装室2的轴心线平行。
本发明的实施例中，通过电机定子安装孔62与安装部本体61上的安装孔62的配合将电机定子固定连接在支撑体上，其中，电机定子安装孔62与安装部本体61上的安装孔62配合的方式包括：
方式一：安装部本体61上开设有螺钉孔，安装时，紧固件采用螺钉，螺钉穿过电机定子安装孔62与安装部上的螺钉孔螺接，其中，螺钉孔为盲孔或通孔，优选地，螺钉孔为盲孔，减小螺钉对外筒底的损坏；
方式二：安装部本体61上开设有非螺钉孔，安装时，紧固件采用螺栓以及螺母，螺栓穿过电机定子安装孔62穿紧非螺钉孔，通过螺栓与螺母螺接将电机定子固定在外筒底上；其中，非螺钉孔为盲孔或通孔，优选地，非螺钉孔为盲孔，减小螺钉对外筒底的损坏。
需要说明的是，由于不同规格电机定子上安装孔62的个数不同，因此可在多条支撑体上设安装孔62以适配不同规格的电机定子，增加该轴套的适用范围，例如，电机定子的安装孔62的个数为八个或四个，那么针对电机定子的安装孔62的个数为四个时，可在八条支撑体上设安装孔62，其中的四个安装孔62能够适配电机定子的四个安装孔62即可；
当电机定子的安装孔的个数为四个时，优选地，四个支撑体上的安装孔处在同一平面上，避免电机在安装时出现倾斜而导致安装不牢固的问题。
此外，安装孔62的轴心线与轴承安装室2的轴心线平行是为了使得安装孔62能够正对电机定子的安装孔62，使得螺钉能够沿直线固定，而不会产生偏移，增加电机定子在外筒底上的牢固性。
本发明的实施例中，安装部本体61上设有类似螺栓的凸起，紧固件采用螺母，安装时，凸起穿过电机定子的安装孔62与螺母螺接以将电机定子固定在外筒底上。
如图2所示，本发明的实施例中，支撑体沿轴承安装室2的径向分为与轴承安装室2的外壁连接的第一子支撑体31，安装部本体61以及与环形外壳1连接的第二子支撑体32三部分；第一子支撑体31以及安装部本体61面向电机定子一侧相对第二子支撑体32凸出设置。
优选的，第一子支撑体31以及安装部本体61面向电机定子一侧凸出的尺寸相等。
本发明的实施例中，沿着轴承安装室2的径向，支撑体规划为了三个部分，三个部分分别为第一子支撑体31、安装部本体61以及第二子支撑体32，第一子支撑体31与轴承安装室2圆滑过渡，第二子支撑体32与环形外壳1圆滑过渡，在上述三个部分中，第一子支撑体31以及安装部本体61均相对第二子支撑体32面向电机定子凸出，第二子支撑体32相对安装部本体61凹陷，对于电机定子而言，在电机定子安装孔62的附近设有凸起，该凸起与第二子支撑体32适配，且凸起上设有卡槽，当安装电机定子时，卡槽能够卡在第二子支撑体32上，能够进一步增加电机定子与外筒后板之间的牢固性。
如图2所示，本发明的实施例中，在轴承安装室2的轴线方向上，安装部本体61的厚度尺寸大于第一子支撑体31以及第二子支撑体32的厚度尺寸。
本发明的实施例中，在轴承安装室2的轴线方向上，安装部本体61相对于第一子支撑体31以及第二子支撑体32向外凸出，由于安装部本体61用于固定连接电机定子，因此，为了避免应力集中，避免安装部6受到变形损坏，于是，将安装部6在垂直于轴承安装室2径向方向上的厚度尺寸设计的比较大。
其中，安装部本体61可为圆柱体，那么，为了避免安装部6受到变形损坏，安装部本体61在垂直于轴承安装室2径向方向的直径大于第一子支撑体31的厚度尺寸以及第二子支撑体32的厚度尺寸。
如图1以及图2所示，本发明的实施例中，支撑体上还设有定位部7，定位部7开设有安装时用于对电机定子定位的定位孔71；
优选的，定位孔71与安装孔62位于一条支撑体上，且定位孔71的轴心线与安装孔62的轴心线平行。
本发明的实施例中，洗衣机轴套包括四条第一支撑体3，四条第一支撑体均匀设置能够使得压力均匀分散，减小对外筒的损坏程度；第一支撑体3除了设有安装孔62，还设有定位孔71，该定位孔71的作用在于在安装电机定子时，对电机定子进行定位，加快电机定子安装孔62与安装孔62的对准速度，从而加快电机定子固定的效率。
在安装电机定子时，手持辅助工具，辅助工具将电机12支撑，使得电机定子安装孔62与安装孔62对准，例如，辅助工具可为带有定位爪的支撑件，安装时，定位爪插入定位孔71内。
举例说明，当支撑体被划分为第一子支撑体31、安装部本体61以及第二子支撑体32时，定位部7设于第一子支撑体31上，且定位部7贯穿第一子支撑体31，沿垂直于轴承安装室2 的径向，定位部7的厚度尺寸大于第一子支撑体31的厚度，避免安装时定位部7应力集中，避免定位部7受到变形损坏。
如图1以及图2所示，本发明的实施例中，支撑体上还设有接地线座8，接地线座8上开设有接地线孔81；
优选的，接地线孔81与安装孔62各自位于一条支撑体上。
本发明的实施例中，洗衣机轴套还包括两条第二支撑体4以及两条第三支撑体5，优选地，四条第一支撑体3、两条第二支撑体4以及两条第三支撑体5均匀布置，两条第二支撑体4位于相邻两条第一支撑体3之间，且两条第二支撑体4对称设置，以及两条第三支撑体5位于相邻两条第一支撑体3之间，且两条第三支撑体5对称设置；在两个第二支撑体4中，第二支撑体4上设有接地线座8，接地线座8上的接地线孔81用于安装接地线，将接地线孔81设在第二辐条条式支撑体上，减轻第一支撑体3的负荷压力。
如图2所示，本发明的实施例中，接地线座8贯穿支撑体以将支撑体规划为与轴承安装室2连接的接地线座8，以及与环形外壳1连接的第三子支撑体41；接地线座8相对第三子支撑体41面向电机定子凸出；且沿垂直于轴承安装室2的径向，接地线座的厚度尺寸大于第三子支撑体41的厚度尺寸。本发明的实施例中，由于接地线座8用于安装接地线，因此，为了避免应力集中，避免接地线座受到变形损坏，于是，将接地线的厚度尺寸设计的比较大；接地线座8相对第三支撑体面向电机定子凸出，便于与电机定子更好地适配，提高电机定子固定的牢固性。
如图1所示，本发明的实施例中，环形外壳1的外壁设有沿环形外壳1周向设置的环形加强筋。
本发明的实施例中，环形加强筋9设于环形外壳1的外壁，能够增加环形外壳1的强度，使得该轴套的强度增加，增强抵抗外力的能力。
对于该洗衣机轴套而言，该洗衣机轴套嵌入外筒底设置，外筒底包括外筒底本体10，洗衣机轴套能够将内筒轴应力均分于外筒底本体各处，提升外筒底的强度，这里所说的嵌入外筒底本体设置不是贯穿外筒底本体设置，其中，洗衣机轴套采用铸铁或者铝合金材质，外筒底采用塑料材质，优选地，洗衣机轴套与外筒底本体10采用注塑的方式一体成型，注塑采用的高分子热塑材料将轴套包裹固定在外筒底上，以提高实现外筒与轴套之间的紧固性，有效降低内筒高速旋转震动产生的噪音；
洗衣机轴套与外筒底本体采用注塑的方式一体成型形成外筒底，洗衣机轴套与外筒底本体之间具有的注塑层上需要保留轴承安装室的通孔，使外筒底上形成供内筒轴穿过的通孔， 洗衣机轴套与外筒底本体之间具有的注塑层上需要保留辐条式支撑体上的安装孔62，使外筒底上形成与电机定子安装孔配合安装的安装孔62，以及洗衣机轴套与外筒底本体之间具有的注塑层上还需要保留辐条式支撑体上的定位孔71，使外筒底上形成配合电机安装的定位孔71。
如图3以及图4所示，本发明的实施例中，外筒底本体10向外延伸有包设在电机12外侧的挡水加强筋11。
本发明的实施例中，外筒底本体10上设有挡水加强筋11，挡水加强筋11包设在洗衣机电机外侧，一方面对洗衣机电机具有稳固的作用，缓冲电机震动幅度，有效降低震动产生的噪音，另一方面能够防止进水泄漏，以及防止冷凝水流入电机，引起短路。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
