Description

一种儿童提篮、儿童推车及儿童汽车安全座椅
本公开要求2022年6月21日提交的申请号为CN2022107052853、CN 2022215604470、CN2022107062253、CN 2022215604466的中国专利申请的优先权。
技术领域
本公开属于儿童用品技术领域，具体涉及一种儿童提篮、儿童推车及儿童汽车安全座椅。
背景技术
为了满足家长和儿童的需求，一些儿童提篮会设计为具有多种使用方式，例如，儿童提篮可安装在儿童推车或儿童汽车安全座椅上，当安装在儿童推车上时儿童提篮的手把杆可作为推车的推把，供使用者推行。除此之外，儿童提篮还可以单独提拎使用，此时手把杆用作供使用者提拎的把手。目前，一些儿童提篮的手把杆同时具备收缩和换向功能，这就需要手把杆上具有至少两套锁定机构，即用于手把杆长度调节的锁定机构以及控制手把杆转动(用于切换手把杆角度使其便于推行或便于提拎)的锁定机构，两套锁定机构大多配置为各自独立工作。然而当儿童提篮需要切换为提拎使用或切换为装在儿童推车或儿童汽车座椅上使用时，既需要控制第一锁定机构以调整手把杆的长度，又需要控制第二锁定机构控制手把杆的转动，操作十分不便。

具体实施方式
在本公开的描述中，涉及到的“前”、“后”、“左”、“右”、“上”、“下”等方向，均是以儿童乘坐时所观察到的方向进行参考定义的，如图1中，图中的左侧方向为“前”，图中的右侧方向为“后”，图中的上侧方向为“上”，图中的下侧方向为“下”，垂直于图中视角的方向为“左”和“右”，对于上述方向的定义仅仅是为了便于描述本公开和简化描述，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公开的限制。
实施例一
如图1至图20所示，本实施例的一种儿童提篮11包括座椅本体12和可伸缩的手把杆13，手把杆13 能够转动地设置在座椅本体12上。
手把杆13包括上手把杆14、下手把杆15和第一锁定机构16。如图3、图6、图11、图14所示，上手把杆14能够沿下手把杆15的长度延伸方向滑动地设置在下手把杆15上，手把杆13与座椅本体12通过转动关节17转动连接。
本实施例中，如图2所示，下手把杆15具有沿其长度方向延伸的管腔，上手把杆14部分插设在管腔中，且能够沿管腔的长度延伸方向滑动地设置。
手把杆13与座椅本体12通过转动关节17转动而至少具有推行挡位和提篮挡位，通过手把杆13相对于座椅本体12转动至不同的角度后对应切换至手把杆13的相应挡位。
当手把杆13处于推行挡位位置时，手把杆13倾斜延伸，如图1、图17和图18所示，手把杆13可以处于伸长状态。如图4所示，手把杆13也可以处于收缩状态，且能够在伸长工作位置或收缩工作位置之间转换。此时，儿童提篮11安装在儿童推车的车架本体128上，作为儿童推车的座兜使用，手把杆13可用于推行儿童推车(即作为儿童推车的推把)，手把杆13的长度可根据推行者的要求进行调节。
推行挡位包括正向推行挡位和反向推行挡位，当手把杆13处于正向推行挡位位置时，手把杆13从后向前向上倾斜延伸，如图1、图4和图17所示；当手把杆13处于反向推行挡位位置时，手把杆13从前向后向上倾斜延伸，如图18所示。
当手把杆13处于提篮挡位位置时，手把杆13沿竖直方向延伸或者倾斜延伸，手把杆13处于收缩工作位置，且不能向伸长工作位置转换。此时，手把杆13主要用于提拎儿童提篮11，该儿童提篮11可以单独提拎使用，如图9所示。
手把杆13还具有防倾斜挡位，防倾斜挡位位于提篮挡位和推行挡位之间。如图15所示，当手把杆13处于防倾斜挡位时，手把杆13与座椅本体12相对固定，以防止提拎儿童提篮时倾倒。
手把杆13还具有安全座椅挡位，如图16所示，当手把杆13处于安全座椅挡位位置时，手把杆13处于收缩工作位置，且不能向伸长工作位置转换。
儿童提篮11还包括第一锁定机构16，第一锁定机构16包括锁定销以及与锁定销121相配合的锁定孔123，锁定销121和锁定孔123中的一者位于上手把杆14上，另一者设于下手把杆15上。第一锁定机构16具有锁定工作状态及解锁工作状态，当第一锁定机构16处于锁定工作状态时，手把杆13被锁定在伸长工作位置或收缩工作位置；当第一锁定机构16处于解锁工作状态时，手把杆13在伸长工作位置或收缩工作位置之间转换，上手把杆14相对于下手把杆15滑动以使得手把杆13伸长或收缩。上手把杆14伸长的过程中，上手把杆14伸出下手把杆15的管腔的长度增加，手把杆13的长度增加。当上手把杆14伸出下手把杆15的长度达到最大时，手把杆13的长度最长。
具体的，如图6所示，第一锁定机构16包括设置于下手把杆15上的锁定销121、复位弹簧122和开设在上把手杆14下部的锁定孔123，当第一锁定机构16处于锁定工作状态时，锁定销121插在锁定孔123内；当第一锁定机构处于解锁工作状态时，锁定销121脱离锁定孔123；当第一锁定机构16在锁定工作状态及解锁工作状态之间转换时，锁定销121相对于下手把杆15滑动，锁定销121的滑动方向垂直于上手把杆14相对于下手把杆15的滑动方向；复位弹簧122设置于锁定销121与下手把杆15之间，复位弹簧122对锁定销121施加有趋于远离锁定孔123方向的力。
儿童提篮11还包括锁定配合机构，锁定配合机构与锁定销121的一端相接触，在手把杆13绕手把杆转轴18相对于座椅本体12转动的过程中，锁定配合机构驱动第一锁定机构16从解锁工作状态转换到锁定工作状态，手把杆13也从推行挡位转换至提篮挡位。锁定配合机构包括设置在座椅本体12的侧面上的导向斜面124，如图8所示，导向斜面124与一手把杆转轴18的轴心线111(手把杆13绕该手把杆转轴18的轴心线相对座椅本体12转动)相交，具体地，导向斜面124自下至上逐渐向远离的手把杆13的方向倾斜。在手把杆13从推行挡位向提篮挡位转换的过程中，导向斜面124推动锁定销121朝着靠近锁定孔123的方向滑动。
继续参照图8，锁定销121具有锁定端部125和驱动端部126，锁定端部125用于插入锁定孔123；在手把杆13从推行挡位向提篮挡位转换的过程中，驱动端部126抵在导向斜面124上并沿着导向斜面124 滑动，导向斜面124距离锁定孔123的距离逐渐变近。
在邻近转动关节17侧的座椅本体12上设置有锁定平面127，手把杆转轴18的轴心线111垂直于锁定平面127，且导向斜面124与锁定平面127相交；手把杆13在提篮挡位与防倾斜挡位或安全座椅挡位之间转换时，驱动端部126抵压在锁定平面127上并相滑动连接，使得第一锁定机构16持续处于锁定工作状态。
转动关节17包括上述的手把杆转轴18、第二锁定机构19和保险机构110，手把杆转轴18的轴心线111沿着座椅本体12的左右方向延伸，第二锁定机构19及保险机构110都具有锁定工作状态及解锁工作状态；当保险机构110处于解锁工作状态时，允许第二锁定机构19从锁定工作状态进入解锁工作状态，此时下手把杆15的下端部与座椅本体12之间可绕手把杆转轴18转动；当保险机构110处于锁定工作状态时，不允许第二锁定机构19从锁定工作状态进入解锁工作状态，此时下手把杆15的下端部与座椅本体12之间的相对位置被锁定。
第二锁定机构19包括第一结合件112、第二结合件113、锁定件114和弹性件115，第一结合件112固定设置于座椅本体12上，第二结合件113固定设置于下手把杆15的下端部，锁定件114设置在第一结合件112和第二结合件113之间，弹性件115抵在锁定件114上，弹性件115用于驱动锁定件114沿着手把杆转轴18的轴心线111方向滑动，使得锁定件114具有同时与第一结合件112和第二结合件113相对位置锁定的趋势。
当第二锁定机构19处于锁定工作状态时，锁定件114分别与第一结合件112和第二结合件113相对位置锁定，当第二锁定机构19处于解锁工作状态时，锁定件114只与第一结合件112和第二结合件113中的一个结合件相对位置锁定，而与另一个结合件相脱离；当锁定件114移动时，第二锁定机构19在锁定工作状态与解锁工作状态之间转换。
第一结合件112上开有径向凹陷的第一凹槽116，第一凹槽116沿手把杆转轴18的轴心线111方向延伸；第二结合件113上开有径向凹陷的第二凹槽117，第二凹槽117沿手把杆转轴18的轴心线111方向延伸。
锁定件114上连接有露出于转动关节17的操作按钮118，锁定件114沿着手把杆转轴18的轴心线111方向轴向滑动地设置，锁定件114上设有径向凸起的齿条119，该齿条119沿着手把杆转轴18的轴心线111方向延伸。
当第二锁定机构19处于锁定工作状态时，齿条119分别插入第一凹槽116内和第二凹槽117内，使得锁定件114同时与第一结合件112和第二结合件113相啮合；当第二锁定机构19处于解锁工作状态时，齿条119脱离其中一个部件上的凹槽，而只插入另一个部件上的凹槽内，使得锁定件114只与第一结合件112和第二结合件113中的一个件相啮合；当按压操作按钮118带动锁定件114轴向滑动时，第二锁定机构19在锁定工作状态与解锁工作状态之间转换。
保险机构110在锁定工作状态下用于锁定锁定件114的移动，在解锁工作状态下允许锁定件114的移动，保险机构110为挡片，当保险机构110处于锁定工作状态且第二锁定机构19也处于锁定工作状态时，挡片120挡在锁定件114的移动路径上；当保险机构110处于解锁工作状态时，挡片120离开锁定件114的移动路径；锁定件114的移动路径指的是第二锁定机构19从锁定工作状态向解锁工作状态转换时，锁定件114的滑动路径，当上手把杆14相对于下手把杆15向下滑动到收缩工作位置时，上手把杆14推动挡片120离开锁定件114的移动路径。
以下对本实施例中儿童提篮11的手把杆13在不同挡位之间切换的过程进行具体介绍：
当手把杆13从推行挡位转换至提篮挡位时，解锁第一锁定机构16，上手把杆14可相对于下手把杆15向下滑动到收缩工作位置。上手把杆14向下滑动的过程中推动挡片120离开锁定件114的移动路径，使得第二锁定机构19能够从锁定工作状态向解锁工作状态转换，手把杆13可以相对于座椅本体12转动至不同的角度。在手把杆13绕手把杆转轴18转动的过程中，第一锁定机构16从解锁工作状态转换到锁定工作状态，即上手把杆14和下手把杆15不能发生相对滑动，手把杆13处于提篮挡位。
当手把杆13从提篮挡位向防倾斜挡位或安全座椅挡位之间转换时，第一锁定机构16始终处于锁定工 作状态，即上手把杆14和下手把杆15不能发生相对滑动。使用者通过按压操作按钮118带动锁定件114轴向滑动，从而解锁第二锁定机构19，以实现手把杆13的转动。
本实施例中的儿童提篮11可以设置在儿童推车的车架本体128上，车架本体128的下方设置有车轮129，如图17至19所示。
本实施例中的儿童提篮11还可以设置在儿童汽车安全座椅的车架本体128上，车架本体128下方设置有车轮129和底座130，如图20所示，车架本体128具有展开使用状态和折叠使用状态，在车架本体128处于折叠使用状态下，车架本体128安装在底座130上。
实施例二
本实施例二与实施例一基本相同，不同之处在于第一锁定机构26的具体结构和运动过程以及锁定配合机构。如图21至图37所示，本实施例的儿童提篮21包括座椅本体22和可伸缩的手把杆23，手把杆23能够转动地设置在座椅本体22上。
手把杆23包括上手把杆24、下手把杆25和第一锁定机构26，如图25、图29、图31和图33所示，上手把杆24能够沿下手把杆25的长度延伸方向滑动地设置在下手把杆25上，手把杆23与座椅本体22通过转动关节27转动连接。
如图21、图34和图35所示，手把杆23处于推行挡位位置且处于伸长状态。如图24所示，手把杆23也可以处于收缩状态，此时，儿童提篮21安装在儿童推车的车架本体231上，作为儿童推车的座兜使用。
如图21、图24和图34所示，手把杆23处于正向推行挡位位置。如图35所示，手把杆23处于反向推行挡位位置。如图28所示，手把杆23处于提篮挡位位置，儿童提篮21可以单独提拎使用。如图30所示，当手把杆23处于防倾斜挡位位置时，手把杆23与座椅本体22相对固定，以防止提拎儿童提篮时倾倒。
手把杆23还具有安全座椅挡位，如图32所示，当手把杆23处于安全座椅挡位位置时，手把杆23处于收缩工作位置，且不能向伸长工作位置转换。
