Description

一种多功能电动折叠轮椅
本申请要求于2019年11月27日在中国专利局提交的、申请号为201911180553.9、发明名称为“一种多功能电动折叠轮椅”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
本申请涉及折叠车的技术领域，具体涉及一种多功能电动折叠轮椅。
 背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然构成现有技术。
折叠轮椅，即一种可以进行折叠调节的轮椅，轮椅包括座位部、靠背部与扶手部，靠背部与扶手部均设置在座位部上，在人们坐在轮椅上时，屁股坐在座位部上，后背则可以靠在靠背部上，而手则可以扶在扶手上。
相关技术方案存在以下缺陷：靠背的倾斜角度不能调节，使得坐在靠背上的人在倚靠靠背时很难处于一个比较舒服的状态，因为靠背安装好之后倾斜角度已经被固定，此时靠背的倾斜角度一般只能适合少部分人，大部分人倚靠时还是处于一个不太舒服的状态中，不利于坐在轮椅上的人休息，故而有待改进。
 技术问题
本申请实施例的目的在于：提供一种多功能电动折叠轮椅，包括但不限于解决轮椅的靠背无法调节而导致舒适度较差的问题。

通过采用上述技术方案，靠背与座位部转动连接，使得靠背的倾斜角度就可以根据使用者的需要进行调节，增加了倚靠的舒适度，便于实际使用；第一伸缩杆的设置，在一定程度上对靠背起到了支撑的作用，使得靠背在向下转动时不至于在重力的作用下快速下降，便于调节靠背到目标倾斜角度上；限位组件的设置，使得靠背调节倾斜角度后可以保持住调节后的状态不发生改变，此时靠背才可以被倚靠，而不会发生在倚靠时向下转动的情况，大大提升了倚靠的安全性。
在一个实施例中，所述座位部包括：车架、前移动件与后移动件，所述车架设置在所述前移动件与所述后移动件上；所述前移动件设置有相互平行的两个，所述后移动件设置有一个，并且两个所述前移动件与一个所述后移动件组成三角形对所述车架进行支撑。
通过采用上述技术方案，车架的设置，将前移动件与后移动件连接起来，使得前移动件与后移动件可以一起带动车架运动；前移动件与后移动件组成三角形对车架进行支撑，使得车架可以稳定的处于前移动件与后移动件上，不易发生侧翻，便于车架上坐人。

通过采用上述技术方案，支撑框架的设置，使得处于轮椅上的人的重量可以大部分作用在两个前移动件上，相比于后移动件只有一个，两个前移动件的支撑效果无疑会更好，使得整个轮椅不易被损坏也不易发生侧翻；第二伸缩杆与第三伸缩杆的设置，一方面对支撑框架上所受到的力进行分散，使得后移动件也可以承担部分支撑框架所受到的力，另一方面在支撑框架受力时，第二伸缩杆与第三伸缩杆通过伸缩可以将支撑框架作用到后移动件上的力抵消一部分，起到了一定的减震作用，提升了轮椅使用的舒适度。
在一个实施例中，所述支撑框架上固定设置有连接件，所述靠背靠近所述座位部一端固定设置有转动杆，所述转动杆与所述连接件转动连接以使所述靠背与所述支撑框架转动连接。

通过采用上述技术方案，齿轮与限位件的设置，使得转动杆的转动可以被控制，在需要调节靠背的倾斜角度时，可以放开限位件对齿轮转动的限制，使得齿轮能够跟随转动杆一起转动，进而达到调节靠背倾斜角度的目的；固定件的设置，使得限位件可以通过向靠近齿轮的方向滑动来限制齿轮转动，通过向远离齿轮的方向滑动来解除对齿轮转动的限制。
在一个实施例中，所述限位件包括盖体与限位齿，所述盖体与所述固定件滑动连接；所述限位齿固定设置在所述盖体上，在所述盖体盖住所述齿轮时，所述限位齿与所述齿轮上的卡齿啮合。
通过采用上述技术方案，盖体的设置，为限位齿的安装提供了位置，而且还为限位齿限制齿轮转动提供了施力的支点，使得限位齿能够稳定的限制齿轮转动。
在一个实施例中，所述盖体一侧表面一体成型有圆形凹槽，所述限位齿一体成型在所述盖体中所述圆形凹槽的侧壁上。
在一个实施例中，所述盖体轴侧外表面上熔接有一个连接块，所述固定件穿过所述连接块且与所述连接块滑动连接。
在一个实施例中，所述支撑框架上固定设置有加强板，所述加强板上固定设置有坐垫。
通过采用上述技术方案，加强板的设置，提升了支撑框架的结构强度以及支撑面积，使得支撑框架不易变形，而且也方便坐垫的安装；坐垫的设置，使得轮椅坐起来更加舒服，不易被硌伤。
在一个实施例中，所述支撑框架边缘处还固定设置有扶手，所述扶手上还固定设置有用于控制轮椅移动方向的转向控制器。
通过采用上述技术方案，扶手的设置，一方面使得坐在轮椅上的人可以有一个抓手的地方，使得坐在轮椅上的人更加容易掌握平衡，另一方面还为转向控制器提供了安装的位置，使得转向控制器可以很方便的被触摸到；转向控制器的设置，使得轮椅在运动时可以通过转向控制器来控制方向，便于对轮椅运动方向的掌控。
在一个实施例中，所述支撑框架远离所述靠背一端设置有用于放脚的踏脚件，所述踏脚件与所述支撑框架铰接。
通过采用上述技术方案，踏脚件的设置，使得坐在轮椅上的人的脚可以被垫起，在轮椅运动时不易发生与地面抵接的情况，一方面减少了脚对轮椅运动的阻力，另一方面还使得地面不易损伤鞋子，而且坐在轮椅上的人的脚也不易悬空，提升了舒适度。
在一个实施例中，所述支撑框架设有前轴和后轴，两所述前移动件均可转动地连接于所述前轴上，所述后移动件可转动地连接于所述后轴上，所述第二伸缩杆远离所述支撑框架的一端可转动地连接于所述后轴，所述第三伸缩杆的一端可转动地连接于所述后轴且另一端可转动地连接于所述前轴。

通过采用上述技术方案，处于同一侧的一根连接杆、一根第二伸缩杆与一根第三伸缩杆组成一个三角形，三角形的顶角处于放置框处，三角形的两个底角分别处于前移动件与后移动件处，在轮椅行驶产生颠簸时，支撑框架上所受到的力可以通过第二伸缩杆传递一部分到后移动件上，减少前移动件的负担，而且在后移动件受力时，后移动件会向后移动，使得第二伸缩杆与第三伸缩杆会被拉长，就会将传递到后移动件上的力抵消一部分，起到缓冲减震的作用，提升了轮椅的舒适性。
在一个实施例中，所述靠背远离所述座位部一端设置有用于对头部进行支撑的头垫，所述头垫与所述靠背可拆式连接。
通过采用上述技术方案，头垫的设置，起到了对头部进行支撑的作用，提升了轮椅使用的舒适度；而且因为头垫与靠背可拆式连接，使得头垫可以进行更换，也可以根据需要选择是否安装。
 有益效果
本申请实施例提供的多功能电动折叠轮椅的有益效果在于：因靠背与座位部转动连接，使得靠背的倾斜角度就可以调节，使用者可以根据自身需要调节靠背到适合自己的位置上，提升了座靠的舒适度，而且此种设计方式的轮椅还可以当做座椅、靠椅或躺椅使用，增加了使用的方式以及使用的范围；而通过限位组件，可以将调节后的靠背限制住，使得靠背不易再发生转动，此时倚靠才不会有危险，提升了轮椅的安全性；
第二伸缩杆与第三伸缩杆的设置，一方面对支撑框架上所受到的力进行分散，使得后移动件也可以承担部分支撑框架所受到的力，另一方面在支撑框架受力时，第二伸缩杆与第三伸缩杆通过伸缩可以将支撑框架作用到后移动件上的力抵消一部分，起到了一定的缓冲减震作用，提升了轮椅使用的舒适度。

为了说明本申请所提供的技术方案，以下结合具体附图及实施例进行详细说明。
参照图1与图3，本申请的一些实施例提供一种多功能电动折叠轮椅，包括座位部1与靠背2，靠背2一端与座位部1一侧铰接；靠背2远离被倚靠面（被倚靠面：人坐在轮椅上靠背2与后背抵接的一侧表面）一侧的表面上设置有对靠背2进行支撑的第一伸缩杆3，第一伸缩杆3一端与靠背2远离被倚靠面一侧表面铰接，另一端与座位部1铰接；座位部1上还设置有固定靠背2倾斜角度的限位组件4。
参照图1与图2，座位部1包括：车架11、前移动件12与后移动件13，车架11设置在前移动件12与后移动件13上；前移动件12与后移动件13均为轮椅车轮，前移动件12设置有相互平行的两个，后移动件13设置有一个，并且两个前移动件12与一个后移动件13在水平面上组成一个等腰三角形对车架11进行支撑，两个前移动件12处于等腰三角形的底角位置，一个后移动件13处于等腰三角形的顶角位置。
参照图1与图2，后移动件13的轴线处穿设有一根后轴131，后轴131通过轴承与后移动件13转动连接，第一伸缩杆3的下端被后轴131穿过，使得后轴131与第一伸缩杆3的下端转动连接，第一伸缩杆3为气弹簧，第一伸缩杆3设置有两根，两根第一伸缩杆3分别设置在后移动件13的两侧，并且两根第一伸缩杆3下端分别与后轴131两端转动连接。
参照图1与图2，车架11包括：支撑框架111、第二伸缩杆112与第三伸缩杆113，支撑框架111为不锈钢材质，支撑框架111设置在两个前移动件12上且用于支撑坐在轮椅上的人，支撑框架111包括放置框1111与四根连接杆1112，放置框1111呈长方形框形，放置框1111设置在四根连接杆1112上，并且在放置框1111上还放置有一个坐垫5，坐垫5呈长方体形状且为软质橡胶材质；四根连接杆1112为两根一组，两组连接杆1112分别设置在坐垫5下方靠近两个前移动件12的两侧，每组中的两根连接杆1112上端分别对应与放置框1111同侧的两个角处焊接，两个前移动件12之间固定设置有一根前轴121，前轴121两端分别穿过两个前移动件12轴线处且分别与两个前移动件12键连接，每组中的两根连接杆1112下端均被前轴121穿过且通过轴承与前轴121转动连接，并且每组中的两根连接杆1112与支撑框架111上对应的一侧组成一个等腰三角形，连接杆1112与前轴121的转动连接处处于两个前移动件12之间。
参照图1与图2，为了驱动轮椅运动，在前轴121上还安装有一个驱动电机1211，驱动电机1211为普通的轮椅电机，驱动电机1211通过驱动前轴121转动，使得前轴121带动前移动件12运动，前移动件12再带动整个轮椅运动。
参照图1与图2，第二伸缩杆112为气弹簧，第二伸缩杆112一端与放置框1111铰接，另一端被后轴131穿过且与后轴131转动连接，第二伸缩杆112设置有两根，两根第二伸缩杆112分别处于后移动件13的两侧，两根第二伸缩杆112靠近放置框1111一端与放置框1111靠近后移动件13一侧的两个角处分别铰接，两根第二伸缩杆112靠近后移动件13一端分别与后轴131两端转动连接，使得支撑框架111受力能够更加平衡；第三伸缩件也为气弹簧，第三伸缩杆113设置有两根，两根第三伸缩杆113一端分别与前轴121靠近两根前移动件12的两端通过轴承转动连接，两根第三伸缩杆113另一端分别与后轴131两端转动连接，此时处于同一侧的一根连接杆1112、一根第二伸缩杆112与一根第三伸缩杆113组成一个三角形，三角形的顶角处于放置框1111处，三角形的两个底角分别处于前移动件12与后移动件13处。
参照图1与图2，为了保持前轴121与后轴131的稳定工作状态，在前轴121分别穿过两个前移动件12的两端、后轴131穿过后移动件13的两端分别套设有螺母，螺母与前轴121以及后轴131均是螺纹连接，使得安装在前轴121上的前移动件12不易与前轴121分离、后轴131不易与后移动件13分离。
参照图1与图2，在轮椅行驶产生颠簸时，支撑框架111上所受到的力可以通过第二伸缩杆112传递一部分到后移动件13上，减少前移动件12的负担，而且在后移动件13受力时，后移动件13会向后移动，使得第二伸缩杆112与第三伸缩杆113会被拉长，因第二伸缩杆112与第三伸缩杆113为弹性伸缩，就会将传递到后移动件13上的力抵消一部分，起到缓冲减震的作用，提升了轮椅的舒适性。
参照图1与图2，为了加强支撑框架111的结构强度，在支撑框架111中的放置框1111上焊接有一块加强板11111，加强板11111为不锈钢材质，坐垫5通过螺栓固定在加强板11111上。
参照图1与图2，为了实现靠背2与座位部1的转动连接，在放置框1111靠近后移动件13一侧焊接有一个连接件11112，连接件11112包括两块相互平行的连接板，连接板呈长方体形状且为不锈钢材质；靠背2靠近座位部1一端焊接有一根转动杆21，转动杆21呈圆柱形且为不锈钢材质，转动杆21穿过两块连接板且分别与两块连接板转动连接，使得靠背2与支撑框架111达到转动连接的目的，进而达到靠背2与座位部1转动连接的目的，连接板上开设有供转动杆21穿过的圆孔。
参照图2与图3，限位组件4包括：齿轮41、固定件42与限位件43，齿轮41套设在转动杆21穿过连接板的一端处且与转动杆21键连接；固定件42呈圆柱形且为不锈钢材质，固定件42焊接在放置框1111上且向远离放置框1111的方向延伸，固定件42与转动杆21平行；限位件43滑动设置在固定件42上用以限制齿轮41转动，使得限位件43通过滑动就可以达到限制齿轮41转动的目的与解除对齿轮41转动的限制的目的。
参照图2与图4，限位件43包括盖体431与限位齿432，盖体431呈圆盘形且为硬质塑料材质，盖体431一侧表面一体成型有圆形凹槽，盖体431轴侧外表面上熔接有一个连接块，连接块呈长方体形状且为硬质塑料材质，固定件42穿过连接块且与连接块滑动连接，固定件42远离放置框1111一端端部位置焊接有一个圆盘，圆盘为不锈钢材质，圆盘的直径大于固定件42的直径且圆盘与连接块形成隔挡，使得连接块滑动时不会完全脱离固定件42；限位齿432一体成型在盖体431中圆形凹槽的侧壁上，限位齿432绕圆形凹槽的侧壁设置有若干个，在盖体431向靠近齿轮41的方向滑动并盖住齿轮41时，限位齿432与齿轮41上的卡齿啮合，此时因盖体431被固定件42限制住不能转动，使得齿轮41也就被限位齿432限制住不能再进行转动，进而达到限制转动杆21与靠背2转动的目的。
参照图3与图4，而在需要转动靠背2（参照图5）时，可以将盖体431向远离齿轮41的方向滑动，使得限位齿432脱离与齿轮41卡齿的啮合，此时齿轮41没有了卡齿的限制就可以转动，进而使得转动杆21与靠背2（参照图5）也就可以转动，达到调节靠背2（参照图5）倾斜角度的目的，此种设计方式，使得该种轮椅可以当做座椅、靠椅或躺椅使用，用途广泛。
参照图2与图5，在支撑框架111靠近两前移动件12的两侧边缘处还各焊接有一个扶手6，使得坐在轮椅上的人可以把两手放在两个扶手6上，在轮椅运动时，坐在轮椅上的人也就坐的更加稳当；扶手6表面还粘连有一层软质橡胶，使得握扶手6时不易出现打滑的情况，而且握着也更舒服；一扶手6上端表面处还通过螺栓固定设置有一个用于控制轮椅移动方向的转向控制器61，有助于在轮椅运动时对轮椅的运动方向进行控制，转向控制技术在一篇专利公开号为CN107714330A的中国专利中已经被公开，在本实施例中就不再做详细的描述。
参照图2与图5，在转向控制器61上还设置有控制驱动电机1211转速的速度按钮；扶手6上还通过螺栓安装有控制驱动电机1211开启与关闭的控制开关62，控制开关62通过导线与驱动电机1211电连接，控制开关62为拨动开关；为驱动电机1211通过导线供电的电池安装在坐垫5的下方，并且处于一个电池盒7中，电池盒7通过螺栓与放置框1111固定连接。
参照图2与图6，为了减少脚对轮椅运动的阻碍，在支撑框架111远离靠背2的一端设置有用于放脚的踏脚件8，踏脚件8一端与支撑框架111中放置框1111远离靠背2一侧铰接，踏脚件8设置有两个，两个踏脚件8平行设置，每个踏脚件8侧表面上均一体成型有一个踏脚槽81，使得坐在轮椅上的人可以将两只脚分别放置在两个踏脚槽81中，此时脚就不会与地面接触，也就不会对轮椅的运动产生阻碍，而且脚还不易出现悬空的情况，提升了舒适性。
参照图6，为了能够对坐在轮椅上的人的头部进行支撑，在靠背2远离座位部1一端设置有一个用于对头部进行支撑的头垫9，头垫9为办公椅头枕，头垫9与靠背2通过螺栓连接，使得坐在轮椅上的人头部可以被支撑，进一步提升了轮椅的舒适度。
本实施例的实施原理为：在人们坐在轮椅上时，首先可以将脚放置在踏脚槽81中，然后开始对靠背2的倾斜角度进行调节，在对靠背2的倾斜角度进行调节时，首先将盖体431向远离齿轮41的方向滑动，使得限位齿432脱离与齿轮41卡齿的啮合，此时再将靠背2向后压动，使得靠背2转动至合适自身的倾斜角度，然后再将盖体431向靠近齿轮41的方向滑动，使得限位齿432与齿轮41的卡齿啮合，此时因盖体431被固定件42限制住不能转动，使得齿轮41不能转动，进而使得转动杆21与靠背2也不能转动，此时人就可以倚靠在靠背2上，而不会出现靠背2再向下转动的情况；在需要驱动轮椅运动时，需要拨动控制开关62，将驱动电机1211打开，然后通过速度按钮控制轮椅的运动速度，同时通过转向控制器61上的方向手柄控制运动的方向。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
