Description

具有安全防护的调节装置 【技术领域】
本发明涉及儿童安全座椅，特别涉及一种具有安全防护的调节装置。
【背景技术】
儿童安全座椅是一种专为不同年龄(或体重)的儿童设计、可安装在汽车内、能有效提高儿童乘车安全性的座椅。为将儿童束缚在安全座椅上，如图11所示，儿童安全座椅通常设有肩带81、胯带82和调节带83(调节带也俗称拉带)。肩带81作用于儿童的胸部和肩部，其部分位于座椅前方(从座椅正面可见，即图11中黑实线所示意的肩带81)，其部分位于座椅背侧(从座椅正面不可见，即图11中黑虚线所示意的肩带81)。跨带82位于儿童的胯部位置处，其一端固定于座椅上，其一端连接有安全扣母扣。肩带81和跨带82通常通过安全扣9进行连接，其可分离和扣合。同时，为适应不同体型的儿童，肩带81和胯带82的松紧度一般可调整，其松紧度的调节，主要是通过调节带83实现。调节带83，又称拉带，其一端与肩带81连接，其另一端为自由端831。调节带83与肩带81即可为固定连接，也可为可拆卸连接。调节带83的自由端831一般露出在儿童安全座椅外，其余部分通常隐藏设置在儿童安全座椅内。在调节带上设有调节器(俗称A-LOCK，按扣、前拉扣，图11中未示出)，调节器固定于儿童安全座椅上，通常是固定在儿童安全座椅前端，位于儿童胯部下方。调节带83穿过调节器，而使得调节带83的中部被调节器固定住。当按压调节器时，调节带83便可沿其长度方向活动。此时若拉住调节带83的自由端831向外拉，调节带83的另一端则拉动肩带81，使肩带81向后收紧，从而使可作用于儿童肩部的肩带部分变短变紧。当按压调节器时，若向外拉动肩带81，肩带81则拉动调节带83向内活动，从而使得作用于儿童肩部的肩带部分变长变松， 以适应儿童的体型。因此，通过调节器和调节带83便可调整肩带81的长度，使肩带81和跨带82的松紧度适应儿童的体型。
众所周知，对于儿童而言，儿童喜欢乱摸乱碰，而调节器一般位于儿童的胯部位置处，极容易被儿童触摸到。如果调节器没有防护装置，乘坐安全座椅的儿童很有可能在不知情的情况下触碰到调节件，从而使得肩带无意中被调松，使安全带失去安全束缚的作用，进而导致安全问题的产生。因此，现有的调节器的结构设计，具有较大的安全隐患，需进一步改善其结构，提高其安全性。

【具体实施方式】
下列实施例是对本发明的进一步解释和补充，对本发明不构成任何限制。
如图1～图9所示，本发明的具有安全防护的调节装置包括连接本体1、防护件2和调节件3。所述连接本体1用于将调节装置固定于儿童安全座椅上，所述调节件3用于调节调节带83，从而调整肩带81与跨带82的松紧程度。所述防护件2与所述调节件3联动设置，其用于保护所述调节件3使得调节件3不易被误操作启动。本发明的主要要点在于，通过防护件2的设置，使得调节装置在默认状态下时，防护件2遮罩住所述调节件3而 使得用户无法直接对调节件3进行操作，从而避免儿童通过直接按压防护件2和/或调节件3而误启调节装置，进而提高调节装置的使用安全性。
实施例1
本实施例的所述防护件2与所述调节件3联动设置，所述防护件2可设置成多种形式，其与所述调节件3联动设置，其部分或全部遮罩住所述调节件3，所述防护件2在默认状态下时与所述连接本体1相抵接而使得防护件2无法被直接按压，避免儿童通过按压而误启调节件3。当推动所述防护件2时，所述防护件2与所述连接本体1脱离而可向下进行按压，此时向下按压便可联动所述调节件3进行转动，从而可对调节带83进行调节，进而可调整肩带81和跨带82的松紧度。
具体地，本实施例中，本发明的防护件2包括呈板状的主体部21、连接部22、搭接部23、连接轴部24。所述主体部21用于手指推动和按压，并用于遮罩所述调节件3。所述主体部21的大小及形状可根据需要而设置。为方便推动和按压所述防护件2，可在所述防护件2的主体部21的上表面设置与手指头相匹配的凹部211，并在凹部211上设置利于增强摩擦的凸条212，从而利于手指作用于所述主体部21而推动和/或按压所述防护件2。本实施例中，所述防护件2被构造成朝座椅内侧方向进行推动以解锁其按压限制，其他实施例中，所述防护件2也可被构造成朝座椅外侧方向进行推动以解锁其按压限制。所述防护件2的表面可根据其推动方向的不同而进行相应的设置，以方便手指推动所述防护件2。例如，当防护件2被构造成朝座椅内侧方向推动时，其推动方向顺应使用习惯，因而在防护件2的主体部21的上表面设置增强摩擦的凸条212即可，或者干脆不设置凸条212也可以。而当防护件2被构造成朝座椅外侧方向推动时，为方便向外拉动所述防护件2，可在所述主体部21的上表面设置相应的作用部，以便于手指作用于其上而向外拉动所述防护件2。
如图9所示，在所述主体部21相对的两侧边缘分别设有竖直的连接部 22。本实施例中，所述连接部22形成于所述主体部21的一端，其他实施例中，所述连接部22可由主体部21边缘的一端延伸至相对的另一端。本实施例中，所述连接部22与所述主体部21相垂直。在所述连接部22的外侧表面分别设有所述连接轴部24，其用于搭接于所述连接本体1上。本实施例中，所述连接轴部24呈圆柱形状，其突出形成于所述连接部22的外侧表面中央。在所述连接部22的端部分别设有竖直的搭接部23，所述搭接部23相向延伸，并与所述主体部21相间隔。所述搭接部23与主体部21相间隔而形成搭接所述调节件3的空间，并使得防护件2可沿调节件3的延伸方向进行推动而不与调节件3脱离。在所述主体部21的内侧表面设有突出于其表面的凸部25，其用于抵接所述第二复位弹簧4。所述凸部25可被构造成多种形状，其可提供作用面用于抵接所述第二复位弹簧4。为更利于抵接所述第二复位弹簧4，本实施例中，在所述凸部25上设有第二定位柱26，该第二定位柱26与所述主体部21平行间隔。本实施例中，所述主体部21、连接部22、搭接部23、连接轴部24、凸部25及第二定位柱26一体成型，其可由多种材料制成，本实施例优选塑料材质。
如图2所示，所述调节件3用于调节调节带83。所述调节件3包括转动部31和作用部32。所述转动部31用于与所述连接本体1转动连接，所述作用部32用于与所述防护件2形成联动设置，使防护件2的运动可作用于所述作用部32上而带动所述转动部31转动。在一些实施例中，所述转动部31可与所述作用部32一体成型，本实施例中，所述转动部31与所述作用部32固定连接，其由不同的材质制成，转动部31由铝材料制成，作用部32由塑胶材料制成，从而不仅可降低加工成本，而且可提升手感和美观性。
如图2所示，本实施例中，所述转动部31被构造成具有第一转轴孔311的不规则体，在所述转动部31的部分表面上设有齿轮形状的齿轮部312，其用于卡持所述调节带83。所述齿轮部312与连接本体1之间具有一定间 隙，其使得调节带83可穿过并夹在齿轮部312与连接本体1之间。所述第一转轴孔311和所述齿轮部312的结构位置关系，使得转动部31形成类似偏心轮的结构，当转动部31转动时，齿轮部312与连接本体1之间的间隙便产生变化。在默认状态时，所述齿轮部312与所述连接本体1之间的间隙最小，其夹紧调节带83而使得调节带83无法活动。当转动部31转动而偏离默认状态位置时，齿轮部312与连接本体1之间的间隙增大，此时调节带83可沿其长度方向活动，从而可通过调节带83的自由端向外拉动调节带83或通过肩带81向内拉动调节带83，进而调整肩带81和跨带82的松紧度。
在所述转动部31的表面上还设有第一定位部313，其用于与所述作用部32定位连接，所述第一定位部313可以是内凹的凹槽，也可以是外凸的凸沿，与之相应的，在所述作用部32上设置相应的凸沿或凹槽，便可使两者卡和在一起，由作用部32的运动而带动转动部31进行转动。本实施例中，所述第一定位部313为内凹的凹槽。
如图2所示，本实施例中，所述作用部32被构造成一端局部包覆于转动部31外而与转动部31形成固定连接，其另一端延伸至转动部31外而利于防护件2作用于其上而与防护件2形成联动连接。本实施例中，所述作用部32的一端半包覆于转动部31外，其形状及大小与所述转动部31相匹配。其他实施例中，所述作用部32的一端也可构造成全包覆于所述转动部31外，以联动所述转动部31转动。在所述作用部32该端的内侧表面设有第二定位部321，所述第二定位部321与转动部31的第一定位部313相匹配，其用于使作用部32与转动部31定位固接，从而可由作用部32带动转动部31动作。本实施例中，所述第二定位部321为突出于其内侧表面的凸沿，其卡入第一定位部313的凹槽内而使转动部31和作用部32定位固接。所述作用部32的用于与防护件2进行联动的连接端的形状与所述防护件2相匹配，本实施例中，其呈平板状，其宽度使得其可搭接于防护件2的主 体部21与搭接部23之间，并搭接于防护件2的搭接部23上，从而使得防护件2可沿着作用部32的侧壁延伸方向进行限位移动而不与作用部32脱离。当作用部32的与防护件2进行联动的连接端搭接于防护件2的搭接部23上时，所述防护件2的主体部21遮罩住作用部32该端的连接端，从而使得用户无法直接操作作用部32而带动转动部31进行转动。在所述作用部32上设有行程孔322，所述行程孔322与所述防护件2的主体部21相对应，主体部21内侧表面的凸部25位于所述行程孔322内。在所述行程孔322的内壁上设有与所述第二定位柱26相对应的第一定位柱323，在所述第一定位柱323和第二定位柱26之间套设有第二复位弹簧4。所述第二复位弹簧4的一端套设于第一定位柱323外，并抵接于行程孔322的内壁上，所述第二复位弹簧4的另一端套设于第二定位柱26上，并抵接于所述凸部25表面上。所述第二复位弹簧4用于使防护件2在无外力作用下时自动复位。在默认状态下时，所述第二复位弹簧4的弹力使得所述防护件2与所述作用部32相对抵接，使防护件2的凸部25限位抵接于行程孔322的与第一定位柱323相对的另一侧侧壁上，从而使得用户可朝第一定位柱323方向推动所述防护件2，使防护件2的凸部25在行程孔322内移动。
如图2所示，所述连接本体1可通过公知的结构与儿童安全座椅固定连接，其设有相对间隔的支撑部11，其用于承载所述调节件3。所述支撑部11间隔的距离与所述转动部31的宽度相一致。在所述支撑部11上分别设有转轴安装孔12，其用于横向连接第一转轴51。所述第一转轴51横向连接于支撑部11之间，所述第一转轴51的两端分别搭接于所述转轴安装孔12内。所述转动部31套设于所述第一转轴51上，从而使得所述转动部31可绕所述第一转轴51转动。为使调节件3自动复位，在所述转动部31与所述第一转轴51之间设有第一复位弹簧6。所述第一复位弹簧6的两端分布设有第一挡臂61，在所述支撑部11上分别设有挡臂孔13，所述第一复位弹簧6的第一挡臂61分别卡接于所述挡臂孔13内，从而使得可通过 第一复位弹簧6的第一挡臂61向所述转动部31施加扭力，在转动部31转动后并失去外力作用时，第一复位弹簧6的扭力可使转动部31转动复位。为使所述第一复位弹簧6作用更顺畅，在所述第一复位弹簧6与所述第一转轴51之间设有胶管7，所述胶管7套设于第一转轴51之外，所述第一复位弹簧6套设于所述胶管7外。
为搭接所述防护件2，使得防护件2被限制而无法直接按压，如图2所示，在所述支撑部11的端部设有阶梯状的阶梯部14。所述阶梯部14包括依次连接的第一作用面141、第二作用面142和第三作用面143。所述第一作用面141与第二作用面142之间形成阶梯状，其用于搭接所述防护件2的连接轴部24。所述第二作用面142与所述第三作用面143之间圆滑过度，其用于使防护件2的连接轴部24脱出所述第二作用面142后沿第三作用面143向下移动。为限制防护件2向下按压的程度，所述阶梯部14还包括与第三作用面143相连的第四作用面144，所述第四作用面144与第三作用面143之间形成阶梯状，其用于限位所述防护件2向下按压的行程。
藉此，便形成了本实施例的具有安全防护的调节装置。所述调节件3的转动部31通过第一转轴51搭接于连接本体1的支撑部11之间，并可绕第一转轴51转动。所述调节件3的作用部32一端与转动部31固定连接，另一端与防护件2联动连接。所述防护件2位于所述调节件3作用部32的上方，并局部遮罩住所述作用部32而使得用户无法直接操作调节件3。所述防护件2的连接轴部24抵接于阶梯部14的第二作用面142上，由于第二作用面142的限位作用而使得防护件2无法被直接按压下去，其状态如图3、图4所示。使用时，如图5、图6所示，朝安全座椅内侧方向推动所述防护件2，使得防护件2的连接轴部24脱出第二作用面142而解除防护件2的按压限制，然后向下按压所述防护件2(如图7所示)，使得防护件2的连接轴部24沿第三作用面143向下移动。如图8所示，防护件2向下移动过程中，其作用于调节件3的作用部32上，从而带动所述转动部31 转动。所述转动部31一转动，夹持在转动部31的齿轮部312与连接本体1之间的调节带83便可沿调节带83的长度方向活动，从而可调节肩带81和跨带82的松紧度。当操作完成而松开按压时，所述第一复位弹簧6的扭力使得转动部31转动复位，第二复位弹簧4的弹力使得防护件2移动复位，从而恢复默认状态(如图3、图4所示)，由防护件2遮罩住调节件3而使得调节件3无法被直接操作，且防护件2被第二作用面142限制住而无法直接按压，进而使得在默认状态下时，调节件3不易被误操作而开启，防止儿童误操作造成安全隐患，提高调节装置的使用安全性。
实施例2
本实施例的防护件2在默认状态下遮罩住所述调节件3而使得所述调节件3无法被误启，当需要启动调节件3时，所述防护件2可活动至其他位置而不影响对所述调节件3的操作。
具体的，如图12、13所示，所述防护件2与所述连接本体1转动连接，其可在外力作用下进行转动，在默认状态时，其可遮罩住所述调节件3；当需要操作调节件3时，所述防护件2可在外力作用下转动一定角度而使所述调节件3显露出来；当不需操作调节件3时，防护件2失去外力作用可自动复位，转回至原位置而遮盖住所述调节件3。
所述连接本体1与调节件3的结构设计可参看现有技术，本实施例的防护件2架构在现有的调节装置的基础上，因此，所述调节件3与所述连接本体1之间可通过多种方式进行连接，其具体结构本实施例不具体介绍，其可参看实施例1的结构，也可参考现有其他公知技术。
所述防护件2包括遮罩盖27和连接于遮罩盖27相对两端的连接臂28。所述遮罩盖27的尺寸以可完全遮盖住所述调节件3为佳，其用于遮盖所述调节件3，使调节件3不容易被直接操作到。所述遮盖罩的形状可根据美观需要而设置，其材质可根据使用需求而设置。所述连接臂28连接于所述遮罩盖27的两端，其与所述遮罩盖27弯折呈一定角度。本实施例中，所述 遮罩盖27与所述连接臂28近似垂直。其他实施例中，其也可不垂直。所述连接臂28与所述遮罩盖27一体成型或一体连接。在所述连接臂28的自由端附近分别设有一个第二转轴孔29，其用于装设第二转轴52而与所述连接本体1转动连接。
在所述连接本体1设有相对间隔的支撑部11，在所述支撑部11上分别设有转轴安装孔12，该转轴安装孔12的位置使得所述防护件2装设于此处后可遮罩住所述调节件3。所述防护件2的连接臂28分别设于所述连接本体1相对的两侧侧壁的外侧，且第二转轴孔29与转轴安装孔12的位置一一对应。在所述第二转轴孔29与转轴安装孔12内共同装设有一第二转轴52，该第二转轴52的两端端部分别搭接于所述连接臂28的第二转轴孔29内，从而使得所述防护件2与所述连接本体1形成转动连接，使得防护件2可绕所述第二转轴52转动。
在所述第二转轴52的两端分别设有端盖，其用于防止第二转轴52移位而脱出所述第二转轴孔29。
为使所述防护件2自动复位，在所述连接臂28与所述连接本体1之间分别设有第三复位弹簧10。所述第三复位弹簧10套设于所述第二转轴52上。在所述第三复位弹簧10的两端分别设有延长的第四挡臂102和第三挡臂101。所述第四挡臂102作用于所述连接臂28上，所述第三挡臂101作用于所述连接本体1上，当防护件2转动一定角度后，在失去外力作用时，所述第三复位弹簧10便通过其第四挡臂102作用于连接臂28上而使防护件2复位，回归至原位置处。本实施例中，所述第四挡臂102的末端呈弯折状态卡在所述连接臂28的边缘，从而可带动所述连接臂28复位转动。其他实施例中，所述第四挡臂102也可设置成其他形式。所述第三挡臂101作用于所述连接本体1上，本实施例中，在所述连接本体1的侧壁上分别设有挡臂孔13，所述第三挡臂101的末端卡接于所述挡臂孔13内。
籍此，便形成了本实施例的具有安全防护的调节装置。在第三复位弹 簧10的作用下，所述防护件2处在遮罩住所述调节件3的位置处，从而避免所述调节件3被误启。当需要操作所述调节件3时，对所述防护件2施加作用力，防护件2便转动一定角度而显露出所述调节件3，从而不影响对调节件3的操作。当操作完，防护件2失去外力作用时，其在第三复位弹簧10的作用下自动复位，继续遮罩住所述调节件3，从而可大大提高连接装置的安全性，避免误操作而带来的安全隐患问题。为便于指示所述防护件2的活动方向，可在所述遮罩盖27的外表面设置操作方向指示符号。在不同的实施例中，所述防护件2的活动方向可根据需要而设置，其既可以是向内转动，也可以是向外转动。
实施例3
本实施例的基本原理同实施例2，所不同的是，实施例2中的防护件2与连接本体1转动连接，本实施例中，所述防护件2可设置成与所述连接本体1滑动连接，其可在外力作用下进行移动。在默认状态时，其可遮罩住所述调节件3；当需要操作调节件3时，所述防护件2在外力作用下移动至其他位置而使所述调节件3显露出来。当不需操作调节件3时，防护件2失去外力作用可自动复位，移动至原位置而遮盖住所述调节件3。
尽管通过以上实施例对本发明进行了揭示，但是本发明的范围并不局限于此，在不偏离本发明构思的条件下，以上各构件可用所属技术领域人员了解的相似或等同元件来替换，例如，如图10所示，当将本实施例的防护件构造成朝座椅外侧方向推动时，所述阶梯部14可设置在连接本体支撑部11的中部以替换设置在端部，与此同时，所述调节件3和防护件2的结构做适应性调整，使得防护件2在推动和向下按压过程时不与连接本体1干涉，使得其可顺利按压下即可。
