Description

扶手组件及其制造方法、支撑架结构和儿童载具 技术领域
本申请涉及婴儿用品领域，具体涉及一种扶手组件及其制造方法、具有该扶手组件的支撑架结构和儿童载具。
背景技术
儿童载具设计时，为考量乘坐儿童的安全性，通常在其扶手处设计有一向前延伸而能防止儿童向前倾落的前扶手。前扶手一般会包覆有具备缓冲功能的保护套，由于儿童具有强烈的好奇心，在儿童乘坐儿童载具时，常常会撕咬拉扯前扶手的保护套，由于该保护套具有缓冲功能，因此均是采用柔性材质制得，极易被儿童撕咬或者拉扯坏，从而导致扶手本体裸露在外而失去缓冲功能及被儿童吞食，严重危害儿童的生命安全。
再者，目前市售婴儿车传统保护套多采用皮革背面涂覆胶层后粘贴EVA(Ethylene Vinyl Acetate Copolymer——乙烯-乙酸乙烯共聚物)，然后再在扶手管表面均匀涂抹一层胶水，将保护套组装至婴儿车的扶手管，需较长时间等待胶水凝固后，保护套才能固定粘贴在扶手管上，该工艺流程复杂，单人一次只能针对一个扶手组件进行加工，耗费人工及工时，且组装后的保护套与扶手管之间的贴合效果不佳，保护套与扶手管没有紧密贴合，出现凹凸不平的褶皱，大大影响了扶手组件及儿童载具的整体美观性。
因此，亟需提供一种可防止填充物暴露于外界，避免儿童误吞填充物从而保障儿童生命安全，且加工操作简单的扶手组件及其制造方法。
申请内容
本申请的目的之一在于，提供一种扶手组件，可防止填充物暴露于外界， 避免儿童误吞填充物从而保障儿童生命安全。
本申请的目的之二在于，提供一种扶手组件的制造方法，一次可加工多个扶手组件，使得组装后的保护套与扶手本体紧密贴合，保护效果好，且加工操作简单。
本申请的目的之三在于，提供一种支撑架结构，具有可防止填充物暴露于外界的扶手组件，避免儿童误吞填充物从而保障儿童生命安全。
本申请的目的之四在于，提供一种儿童载具，具有可防止填充物暴露于外界的扶手组件的支撑架结构，避免儿童误吞填充物从而保障儿童生命安全。
为实现上述目的，本申请提供了一种扶手组件，包括扶手本体，其中，扶手本体外包覆一层柔性结构的第一保护层，第一保护层外包覆有第二保护层，第二保护层遮挡第一保护层避免第一保护层暴露于外界。
与现有技术相比，由于本申请的扶手组件，扶手本体外包覆一层柔性结构的第一保护层作为填充物，该柔性结构具备缓冲功能，防止儿童因前倾时撞到坚硬的扶手组件而对儿童造成伤害，扶手组件的第一保护层外包覆一层防撕咬的第二保护层，第二保护层具备耐磨、韧性强、密封性好和抗拉扯的性能，且第二保护层遮挡第一保护层暴露于外界，第二保护层将第一保护层完全封闭在内，可防止填充物第一保护层暴露于外界，避免儿童误吞填充物第一保护层从而保障儿童的生命安全；同时，两层保护层结构不仅对儿童的保护效果好，且强度好，耐用，使用寿命长，尤其是第二保护层采用皮革结构，能大大提升扶手组件的质感，即提升儿童载具整体的档次和外观性。
较佳地，本申请的第二保护层的两端分别弯折延伸形成包覆第一保护层两端的弯折段。由于第一保护层的端部比较容易外露，通过设置弯折段，可很好的防止第一保护层的端部外露，避免儿童撕咬而误吞，以保障儿童的生命安全。
较佳地，本申请的弯折段的末端伸至所述扶手本体的端部并与扶手本体的端部至少部分贴合。如此增加了弯折段的长度和包覆面积，使得第一保护层的端部更加不易外露，能更好的保障儿童的生命安全。
较佳地，本申请的弯折段形成贯穿的中空结构，扶手本体的端部的中央区域借由中空结构的贯穿口暴露于外。如此方便扶手本体穿过由第一保护层和第 二保护层组合形成的保护套，从而大大提升扶手组件的生产加工效率。
较佳地，本申请的第二保护层的弯折段绕过第一保护层的端部并嵌入至第一保护层与扶手本体的接触面之间，弯折段与扶手本体连接。如此增加了第一保护层端部被包覆的长度，即第一保护层端部的外侧和内侧均被包覆，且弯折段被扶手本体与第一保护层夹紧，使得弯折段不会外翻出来，从而能更好的防止第一保护层的端部露出，以防止儿童撕咬外露的第一保护层而误吞从而更好的保障儿童的生命安全。
较佳地，本申请的弯折段形成中空的筒状结构，筒状结构套设于扶手本体外。这样在扶手本体穿过第一保护层和第二保护层时，不会使得弯折段外翻，以保证弯折部包覆第一保护层的端部的效果，很好的防止第一保护层的端部外露。
较佳地，本申请的扶手本体为呈中空结构的刚性管件。中空结构的扶手本体，不仅可减轻扶手组件的重量，以减轻儿童载具整体的重量，方便使用及收纳搬运，且加工用料少，成本低。

较佳地，本申请的步骤(23)位于步骤(22)之前，所述弯折段可与所述第二保护层一同与第一保护层固定。如此可将弯折段的固定与保护套与扶手本体的固定同时进行，生产效率更高。
较佳地，本申请的步骤(23)中弯折段通过烘烤第二粘合层以与第一保护层固定连接；或者，所述步骤(23)中弯折段通过胶水以与第一保护层固定连接。通过此两种方式均可将弯折段与第一保护层固定连接，其固定方式简单且可靠，使得弯折段不易松脱。
较佳地，本申请的步骤(3)进一步包括如下，将所述基材层卷曲并车缝或手工缝为与扶手本体相匹配的保护套的步骤。通过车缝或手工缝，以形成保护套，不仅方式简单，方便生产加工，还使得保护套的接合处形成一道缝纫线，可很好的提升保护套的质感。
较佳地，本申请的第一粘合层和所述第二粘合层呈膜结构。采用膜结构的粘合层，其平整性、延展性好，方便粘合层的放置、铺展以及在后续烘烤热熔时能很好的保证位置固定，不会错位或移位，从而方便后续的烘烤热熔，以保证粘合后的强度，使得两个保护层之间以及保护套与扶手本体之间不易松脱，进而保证保护套的保护效果。

(6)冷却经过烘烤后的扶手组件毛坯形成所需的扶手组件10。
具体的，预留段为在将第一保护层12粘合固定于第二保护层13上时第二保护层13的边缘未被第一保护层12覆盖的部分形成，从而将预留段向下弯折以形成弯折段131。
本方法中，通过设置弯折段及其加工方法，并将弯折段绕过第一保护层的端部并嵌入至第一保护层与扶手本体的接触面之间，弯折段与扶手本体连接。如此增加了第一保护层端部被包覆的长度，即第一保护层端部的外侧和内侧均被包覆，且弯折段被扶手本体与第一保护层夹紧，使得弯折段不会外翻出来，从而能更好的防止第一保护层的端部露出，以防止儿童撕咬外露的第一保护层而误吞从而更好的保障儿童的生命安全。
具体的，预留段为在将第一保护层12粘合固定于第二保护层13上时第二保护层13的边缘未被第一保护层12覆盖的部分形成，从而将预留段向下弯折以形成弯折段131。
具体的，第一保护层12呈柔性且具有弹性的结构，弹性结构具备缓冲功能，防止儿童因前倾时撞到坚硬的扶手组件而对儿童造成伤害。
更具体的，第一保护层12为EVA泡棉，第二保护层13为PU，如此以保 证形成的保护套的保护效果好，且有质感，档次高，且便于两种保护层之间的粘合固定，其牢固性好，不易松脱或分层或褶皱，一体结构感强，质感好，外观性好，同时此两种材料易获取，采购成本相对较低，可很好的降低生产加工成本。
具体的，第一粘合层14和第二粘合层15均为呈膜结构，其平整性、延展性好，方便粘合层的放置、铺展以及在后续烘烤热熔时能很好的保证位置固定，不会错位或移位，从而方便后续的烘烤热熔，以保证粘合后的强度，使得两个保护层之间以及保护套与扶手本体之间不易松脱，进而保证保护套的保护效果。
更具体的，扶手本体11为中空结构的金属管件，第一粘合层14选用TPU热熔胶膜，TPU热熔胶膜表面光滑，方便扶手本体11穿过保护套，以方便生产加工，提升生产加工效率，由于扶手本体为金属材质，采用TPU热熔胶膜粘合效果更佳，粘合更牢靠，但不限于此，第一粘合层113还可以为PU热熔胶膜、PP热熔胶膜、PS热熔胶膜和PA热熔胶膜中的一种。
第一粘合层14可采用热压或真空吸附的方式粘合固定于第一保护层12与扶手本体11接触的表面上，如此方便第一粘合层14的固定，且固定可靠，不会脱落或移位或错位，保证保护套与扶手本体之间固定的可靠性和稳定性，其余可实现将第一粘合层14粘合固定于第一保护层12上的粘合固定方式均属于本申请所涵盖的范围。
第二粘合层15可采用热压或真空吸附的方式粘合固定于第二保护层13与第一保护层12接触的表面上，这样预先将第二粘合层15固定于第二保护层13上，可避免第一保护层12与第二保护层13在粘合固定时，第二粘合层15移位或错位，以保证第一保护层12与第二保护层13粘合固定的可靠性，其余可实现将第二粘合层15粘合固定于第二保护层13上的粘合固定方式均属于本申请所涵盖的范围。
当然，能理解的，上述的烘烤温度为恒温温度，即不随烘烤时间的长短而升高或降低。
可以理解的，步骤(23)也可以位于步骤(22)后面，即在第一保护层与第二保护层粘合固定后，再对弯折段进行粘合固定，如此也可以很好的将弯折 段粘合固定，以保证对第一保护层端部的包覆效果。
可以理解的，第一保护层12也可以为软胶结构或其他泡棉。
可以理解的，第二保护层13也可以为PVC或真皮或其他皮革材质。
可以理解的，第一保护层12与第二保护层13之间也可通过胶水粘合固定，胶水粘合的方式简单，且固定可靠，成本较低。
可以理解的，弯折段131也可以通过胶水与第一保护层粘合固定。
可以理解的，第二粘合层15也可以采用热压或真空吸附的方式粘合固定于第一保护层12与第二保护层13接触的表面上，其余可实现将第二粘合层15粘合固定于第一保护层12上的粘合固定方式均属于本申请所涵盖的范围。
可以理解的，步骤(3)中可以将基材层卷曲并车缝或手工缝为与扶手本体11相匹配的保护套，不仅方式简单，方便生产加工，还使得保护套的接合处形成一道缝纫线，可很好的提升保护套、扶手组件以及儿童载具整体的质感和档次。
可以理解的，烘烤温度也可以为80℃、85℃、90℃、95℃、100℃、105℃、110℃、115℃、120℃、125℃、135℃、140℃、145℃、150℃等，具体根据扶手本体的材质以及热熔胶膜的类型而定。
可以理解的，烘烤时间也可以为2分钟、2.5分钟、3分钟、3.5分钟、4.5分钟、5分钟、5.5分钟、6分钟等，具体根据扶手本体的材质以及热熔胶膜的类型而定。
可以理解的，扶手本体11可以为中空结构的塑料管件或实心的塑料管件，较佳的，第一粘合层14可选用PP热熔胶膜，其粘合效果更佳，粘合更牢靠。
当然，还能理解的，上述各实施例中所称的扶手组件，是一种上位概念，即用于乘坐者或推车者手握的部分均可认为是扶手组件，不仅仅是指婴儿推车面向乘坐者的前侧扶手，也可指代车架上的车手或车把或握手等。
以上所揭露的仅为本申请的较佳实例而已，不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，均属于本申请所涵盖的范围。
