Description

电动床垫 技术领域
本实用新型涉及床垫，尤其涉及一种可调节角度的电动床垫。
背景技术
随着人们生活水平及生活品质的不断提高，家居使用的床需要有可以活动调节的功能，使人们能够根据个人喜好选择最舒服的躺卧姿势。具备这种功能的床被称为活动床。
而目前的活动床大多采用固定的床架和可活动的床面的结构。具体来讲，这种活动床是由床架上设置的驱动装置推动床面的前部、中部及后部以作适当角度的调整，从而满足不同用户对床的不同使用需求。如果驱动装置为电机，则活动床称为电动床。
在现有技术的活动床中，床面包括由多节板面或板架活动枢接在一起构成的床面架及床垫，床垫由多块配合板面或板架大小的垫体拼构而成，要么是各块垫体被独立设置，要么是依靠床罩将各块垫体连接在一起形成整体床垫。
由此可见，现有技术的活动床的各部分较为独立，且床架的驱动装置多是裸露在外，整个活动床采用较为繁琐的结构，使用不方便。此外，由于床架一般较重，在使用中造成了诸多不便，例如，仅仅适用于室内，且一旦位置选择好，就很难改变，而且时间久了容易造成审美疲劳。
实用新型内容
鉴于上述问题，本实用新型提供一种可灵活方便地调节角度的电动床垫。
根据本实用新型的第一方面，一种电动床垫包括床垫框架和包裹在床垫框架周围的床垫外包层，其中，该床垫框架包括靠背部、座位部、大腿部和小腿部，其中，座位部与靠背部之间、座位部与大腿部之间、 大腿部与小腿部之间为转动连接，并且座位部与靠背部之间的角度和座位部与大腿部之间的角度可被调节至规定角度。
根据本实用新型的第二方面，所述座位部配备有第一电驱动装置和第二电驱动装置，第一电驱动装置驱动所述靠背部相对于所述座位部进行转动，第二电驱动装置驱动所述大腿部相对于所述座位部进行转动。
根据本实用新型的第三方面，所述第一电驱动装置驱动所述靠背部相对于所述座位部向上转动；所述第二电驱动装置驱动所述大腿部相对于所述座位部向上转动，在此状态下，所述小腿部在重力作用下相对于所述大腿部向下转动。
根据本实用新型的第四方面，所述第一电驱动装置包括第一电机和与之相连的第一电机推杆，第一电机固定在所述座位部的第一电机定位座上，第一电机推杆固定连接至第一电机推杆定位座，第一电机推杆定位座固定在与所述靠背部一起转动的第一转轴上；所述第二电驱动装置包括第二电机和与之相连的第二电机推杆，第二电机固定在所述座位部的第二电机定位座上，第二电机推杆固定连接至第二电机推杆定位座，第二电机推杆定位座固定在与所述大腿部一起转动的第二转轴上。
根据本实用新型的第五方面，所述靠背部与所述座位部之间的角度范围是104度至180度，所述大腿部与所述座位部之间的角度范围是138度至180度。
根据本实用新型的第六方面，所述床垫框架还包括底座部，所述底座部固定连接至所述座位部的底部。
根据本实用新型的第七方面，所述床垫外包层由作为内层的高回弹海绵和作为外层的黄麻板组成。
根据本实用新型的第八方面，所述电动床垫还包括：控制器，其对所述第一电驱动装置和所述第二电驱动装置进行独立控制。
根据本实用新型的第九方面，所述控制器是有线控制器。
根据本实用新型的第十方面，所述控制器是无线控制器。
本实用新型提供的电动床垫中由于内置了电机，可以达到电动床同样的效果，既可以放置在室内的地板上，也可以在室外使用，只要附近有电源即可。而且，本实用新型提供的电动床垫实现了床垫和床架的分 离，满足消费者多种场合使用的需求。

具体实施方式
为使本领域技术人员更好地理解本实用新型的技术方案，下面结合附图和具体实施方式对本实用新型提供的电动床垫进行详细描述。在这些附图中，对于相同或者相当的构成要素，标注相同标号。以下仅为本实用新型的电动床垫的最佳实施方式，本实用新型并不仅限于下述结构。
图1是本实用新型的一个实施方式的电动床垫1的立体图。如图1所示，电动床垫1并不像现有技术的床垫那样必须与床架一起使用。由于内置有电驱动装置(图中未示出)，电动床垫1可以由用户根据需要调节到舒适的角度，例如图1所示，背部抬高后，方便躺在上面阅读，也方便腿脚不便的老人独立起居；腿部抬高后，可以加速腿部血液回流，降低心脏压力，具有一定的心脏保健功能。
本实施方式的电动床垫1需要外接电源，因此可以将电动床垫1 放置在有电源接口的任意场所，例如客厅、阳台等，或者庭院中。另外，在另一个实施方式中，电动床垫也可以内置可充电电源，在这种情况下，电动床垫的应用场所就更广，只要保证足够的电量即可。
图1中并未示出，电动床垫1还配有控制器，控制器对电动床垫1内的电驱动装置进行控制，从而调节电动床垫的角度。控制器可以是有线控制器，也可以是无线控制器。
另外，为了方便拆洗和清洁，电动床垫1的外部还采用了“可脱洗外罩”。
下面参照图2-图4详细说明电动床垫1的结构。
图2是电动床垫1的局部剖视图。
如图2所示，电动床垫1包括床垫框架10和包裹在床垫框架10周围的床垫外包层11。
在图2中，床垫框架10主要由起骨架作用的钢架框20和起表面支撑作用的铁皮21组成。在其他实施方式中，床垫框架也可以由铁架和钢丝网组成。
床垫外包层11可以由海绵22和黄麻板23组成。在图2中，床垫框架10的侧面可以选用高回弹海绵，底面可以选用普通海绵，而在顶面上，为了考虑用户的舒适性，采用高回弹海绵和黄麻板的双层结构。在其他实施方式中，可以根据用户的不同需求，可以用椰棕代替黄麻。
图3是电动床垫1的床垫框架10的未调节状态的立体图。
如图3所示，床垫框架10包括靠背部101、座位部102、大腿部103和小腿部104，其中，座位部102与靠背部101之间、座位部102与大腿部103之间均为角度可调的转动连接，大腿部103与小腿部104之间为转动连接。
另外，床垫框架10还可以包括起平衡支撑作用的底座部105。
在图3的平放状态下，电动床垫1从外观上与普通的床垫没有任何差异。
图4是电动床垫1的床垫框架10的调节后状态的立体图。
如图4所示，电动床垫1的靠背部101相对于座位部102向上转 动，大腿部103相对于座位部102也向上转动，小腿部104在重力作用下相对于大腿部103向下转动。
在图4的调节状态下，电动床垫1的外观如图1所示。
如上所述，电动床垫1的角度调节功能使通过使靠背部101和大腿部103相对于座位部102发生转动而实现的。
下面参照图5和图6详细说明电动床垫1的角度调节原理。
图5是床垫框架10的座位部102的工作原理的立体图。
图6是床垫框架10的座位部102的工作原理的侧面图。
座位部102设置有第一电驱动装置和第二电驱动装置。
如图5所示，第一电驱动装置包括第一电机106和与之相连的第一电机推杆107。第一电机106固定在座位部102的第一电机定位座110上，第一电机推杆107固定连接至靠背部101。
此处，第一电机推杆107通过第一电机推杆定位座112固定连接至转轴113，转轴113两端的旋转固定片114与靠背部101(图中未示出)固定连接。
如图5所示，第二电驱动装置包括第二电机108和与之相连的第二电机推杆109。第二电机108固定在座位部102的第二电机定位座111上，第二电机推杆109固定连接至大腿部103。
此处，第二电机推杆109通过第二电机推杆定位座115固定连接至转轴116，转轴116两端的旋转固定片117与靠背部101(图中未示出)固定连接。
图5的(A)示出了第一电机106和第二电机107对靠背部101和小腿部13进行了角度调节后的状态；图5的(B)示出了第一电机106和第二电机107未对靠背部101和小腿部13进行角度调节的状态。
再来参照图6的侧面图，同样，图6的(A)示出了第一电机106和第二电机107对靠背部101和小腿部13进行了角度调节后的状态；图6的(B)示出了第一电机106和第二电机107未对靠背部101和小腿部13进行角度调节的状态。
从图6的(A)中可以看出，靠背部101(旋转固定片114)与座位部102之间的角度范围是104度至180度，大腿部103(旋转固定 片117)与座位部102之间的角度范围是138度至180度。
应该理解，上述角度范围仅仅是示例性的，通过选择第一电机106和第二电机107的行程长度，可以对调节角度范围进行改变。
下面参照图7至图11说明床垫框架10的各个组成部分之间的连接关系。
图7是床垫框架10的靠背部101的立体图。如图7所示，靠背部101固定连接至旋转固定片114。第一电机推杆定位座112与第一电机推杆107相连。第一电机推杆定位座112和旋转固定片117固定连接至转轴113并随之一起转动。旋转固定片112与靠背部101固定连接，当转轴113转动时，带动靠背部101一起转动。
图8是床垫框架10的座位部102的立体图。图8中并未示出两个电机106和108，而仅仅示出了第一电机定位座110和第二电机定位座111。图8中还示出了与大腿部103固定连接的旋转固定片117。因为座位部102与靠背部101和大腿部103之间的连接已经在图5中详细给出，所以这里省略相应的说明。另外，座位部102上设置有螺孔121′和122′，用于通过螺栓将座位部102固定到底座部105。
图9是床垫框架10的大腿部103的立体图。第二电机推杆109连接至图9中的第二电机推杆定位座115。第二电机推杆定位座115和旋转固定片117固定连接至转轴116并随之一起转动。旋转固定片118与大腿部103固定连接，当转轴116转动时，带动大腿部103一起转动。另外，如图9所示，大腿部103一侧还设置有用于和小腿部14连接的一对安装座119。
图10是床垫框架10的小腿部104的立体图。小腿部104的一侧设置有一对U字架120，大腿部103的安装座119与小腿部104的U字架装配在一起，使得大腿部103和小腿部104可以进行相对转动。
图11是床垫框架10的底座部105的立体图。如图11所示，底座部105是矩形的框架，其对应的长侧分别设置有一对安装件121和122，用于通过例如螺栓等安装到座位部102的螺孔121′和122′，参见图8。底座部15的作用是平衡并支撑整个床垫框架10。
本实用新型的电动窗垫可以根据用户的意愿在一定范围内连续调 节角度，容易找到一个舒适的角度，对于用户的背部、臀部、大腿和小腿都能进行支撑。并且在用户使用了一段时间之后，随时调节角度避免身体长时间处于某个角度而疲劳。
以上实施方式仅仅是为了说明本实用新型的原理而采用的示例性实施方式，然而本实用新型并不局限于此。对于本领域内的普通技术人员而言，在不脱离本实用新型的精神和实质的情况下，可以做出各种变型和改进。这些变型和改进也视为本实用新型的保护范围。
