Description

一体式自开自闭爬楼梯拉杆箱 技术领域
本发明涉及箱包领域，尤其是涉及一体式自开自闭爬楼梯拉杆箱。
背景技术
行李箱是人们外出远行必不可少的工具，传统的拉杆箱大多只能在比较平整的路上拖动，而上、下楼梯时，只能提在手里或扛在肩上，不仅费劲，而且费时，尤其是拉杆箱特别重时，更加吃力，磕磕绊绊甚至搬不动。
目前市场上的可以方便上下楼梯的行李箱多为六转轮或单一大转轮式，对不同坡度的阶梯普适性差，高一点的台阶且需要很大的力气拉动，十分费力，而且由于没有减震装置和缓冲装置，爬楼过程跳动和噪音都很大，易对行李箱本身或内部易碎品造成较大伤害，尤其是六转轮和大转轮式都是定向轮，不能推着走，只能拉着走不省力，而且体积大影响外观，也不方便放置。
发明内容
本发明的目的在于提供一体式自开自闭爬楼梯拉杆箱。
为实现上述目的，本发明采用以下内容：
一体式自开自闭爬楼梯拉杆箱，包括箱体、万向轮、伸缩拉杆、 滑板、单向轮、弹性装置、减震装置、限位连杆、扭簧连杆、内托、第一连接杆、第二连接杆、第三连接杆和第四连接杆，所述箱体的底部设置有万向轮，所述滑板的底部设置有单向轮，所述伸缩拉杆设置于箱体的一侧，所述内托分别与箱体和伸缩拉杆连接，左右两侧的所述限位连杆通过第一连接杆与内托活动连接，通过第二连接杆与滑板活动连接，左右两侧的所述扭簧连杆通过第三连接杆与内托活动连接，通过第四连接杆与滑板活动连接，所述限位连杆、内托、扭簧连杆和滑板之间形成双摇杆机构，所述弹性装置的一端与内托连接，另一端与第四连接杆连接，所述减震装置设置于滑板与内托之间，所述滑板通过弹性装置以及减震装置的弹力，带动单向轮向上位移，直至所述限位连杆的顶部抵接内托为止，使滑板相对于箱体处于常闭状态，此时所述单向轮的底部水平线高于万向轮的底部水平线；当所述滑板受到外力作用下，所述滑板带动单向轮向下位移，直至所述扭簧连杆的底部抵接内托为止，使滑板相对于箱体处于打开状态，此时所述单向轮的底部水平线低于万向轮的底部水平线。
优选地，所述弹性装置为拉簧或橡皮筋。
优选地，所述减震装置为扭簧，所述扭簧套设于第三连接杆的两端。
优选地，所述滑板的横截面呈“凵”字型，所述箱体上开设有与滑板的两侧相适配的槽口，所述滑板的两侧卡设于槽口上且与箱体之间形成容纳腔，所述弹性装置、减震装置、限位连杆、扭簧连杆、内托、第一连接杆、第二连接杆、第三连接杆和第四连接杆均设置于容 纳腔内。
优选地，还包括肩跨带，所述肩跨带的一端穿过日字扣后形成用于肩部跨背的大闭合圆环，另一端与伸缩拉杆的顶部连接。
优选地，所述箱体或伸缩拉杆上设置有空腔，所述空腔内设置有移动充电宝。
优选地，所述滑板采用瓦楞结构。
优选地，所述滑板的左右两侧均设置有拱形凸块。
优选地，所述拱形凸块上设置有可拆卸耐磨条，或所述拱形凸块上设置有滑槽，所述滑槽内设置有滑条。
优选地，所述滑板的顶部和内托的底部均设置有缓冲海绵或弹簧。
本发明具有以下优点：
1)、本发明在光滑路面可通过箱体底部的四个万向轮自由推拉，相当省力。通过砂石、土路、山路等复杂的路况时，切换成单向轮拖着走。单向轮轴承较大，而且是定向比较稳定，不像万向轮那样在坑坑洼洼的地面会来回跳动。如遇到台阶或楼梯可直接利用滑板以及滑板下的单向轮相互配合下快速穿越通过。本发明操作简单使用方便，且适应各种复杂路况，便于人们出行使用；
2)、本发明在上或下楼梯时，通过拉簧、扭簧以及缓冲海绵起到减震和缓冲功能，不会对行李箱本身或内部易碎品造成较大伤害，也不会产生很大噪音和震动；
3)、本发明采用滑板爬楼梯，由于滑板的跨度更大，可以通过 提高或放低伸缩拉杆改变切入角度，即可满足各种坡度的阶梯；
4)、本发明中滑板等装置均可隐藏在箱体的后幅下部，处于常闭状态下时，滑板与箱体浑然一体，从外观上很难看出和普通拉杆箱的区别，更加美观；
5)、本发明中设置有搭配伸缩拉杆使用的肩跨带，当行李超重时将肩跨带索在拉杆的把手上，然后像包一样跨在肩上，用肩辅助拖着拉杆箱上、下楼梯。平路也可以跨在肩上拖着拉杆箱滑行，这种独特设计既省力又解放了我们双手，大大方便了人们出行。

实施例一
如图1至10所示，本实施例的一体式自开自闭爬楼梯拉杆箱，包括箱体1、伸缩拉杆2、万向轮3、滑板4、单向轮5、弹性装置6、减震装置7、限位连杆8、扭簧连杆9、第一连接杆10、第二连接杆11、第三连接杆12、第四连接杆13和内托18。箱体1的底部设置有万向轮3，滑板4的底部设置有单向轮5，所述伸缩拉杆2设置于箱体1的一侧。由于箱体1采用吸塑工艺，不能局部加厚，因此在箱体与伸缩拉杆之间安装内托，内托18的一侧与伸缩拉杆2的底托通过螺丝或铆钉连接固定连接，另一侧与箱体1的底部连接。左右两侧的限位连杆8通过第一连接杆10与内托18活动连接，通过第二连接杆11与滑板4活动连接，左右两侧的扭簧连杆9通过第三连接杆12与内托18活动连接，通过第四连接杆13与滑板4活动连接，第一连接 杆10、第二连接杆11、第三连接杆12和第四连接杆13均采用长滚花销钉，4个长滚花销钉作连接零件，把滑板4、限位连杆8、扭簧连杆9和内托18连接起来，使限位连杆8、内托18、扭簧连杆9和滑板4之间形成双摇杆结构，保证限位连杆8、扭簧连杆9能传递运动和转矩，减震装置7采用扭簧，也可以采用弹簧，扭簧套设于第三连接杆12的两端，所述弹性装置6采用拉簧，内托的中间位置设置挂钩，拉簧的一端与内托上的挂钩连接，另一端连接在第四连接杆13的中间，滑板4通过拉簧以及扭簧的弹力，带动单向轮5向上位移，直至限位连杆8的顶部抵接内托为止，使滑板4相对于箱体1处于闭合状态，此时所述单向轮5的底部水平线高于万向轮3的底部水平线；当所述滑板4受到外力作用下，所述滑板4带动单向轮5向下位移，直至扭簧连杆9的底部抵接内托为止，使滑板4相对于箱体1处于打开状态，此时单向轮5的底部水平线低于万向轮3的底部水平线，为了防止爬楼梯过程中挂到万向轮，而额外增加摩擦力，靠近单向轮的万向轮3底座可采用加宽偏轴方式或者万向轮整体前移方式，使万向轮的轮子远离单向轮，也就是说，爬楼梯时候只有单向轮参与活动，万向轮不参与，这样滑行起来就会更加顺畅平稳。
本实施例的一体式自开自闭爬楼梯拉杆箱中，所述滑板4的横截面呈“凵”字型，所述箱体1上开设有与滑板4的两侧相适配的槽口20，滑板4相对于箱体1处于常闭状态时，所述滑板4的两侧卡设于槽口20内且与箱体1之间形成容纳腔21，所述弹性装置6、减震装置7、限位连杆8、扭簧连杆9、内托18、第一连接杆10、第 二连接杆11、第三连接杆12和第四连接杆13均设置于容纳腔21内，处于常闭状态下时，滑板与箱体浑然一体，从外观上很难看出和普通拉杆箱的区别，更加美观。
本实施例的一体式自开自闭爬楼梯拉杆箱中，还包括肩跨带14，肩跨带14的一端依次穿过柔性材料制成的防护垫和日字扣15后形成用于肩部跨背的大闭合圆环，并通过双面铆钉固定，肩跨带14的另一端折叠并通过双面铆钉固定形成小闭合圆环，使用时，根据不同使用者的身高通过日字扣15调整肩跨带14的长度，将肩跨带14的大闭合圆环部分缠绕在伸缩拉杆2的顶部把手上并从小闭合圆环穿出，使得肩挎带14与伸缩连杆2临时活动连接，通过肩挎带14拖着拉杆箱进行上下爬楼，平路也可以像包一样跨在肩上拖着拉杆箱滑行，既省力又解放了双手。不用时，肩跨带14还可以从伸缩拉杆2上取下来，肩跨带14折叠后只有打火机般大，便于携带。但不仅限于此，肩挎带14的另一端可以直接绑在伸缩拉杆2的顶部上，或通过按扣、挂钩等方式与伸缩拉杆2活动连接。
本实施例的一体式自开自闭爬楼梯拉杆箱中，伸缩拉杆的顶盖上设置有能插入移动充电宝的空腔，移动充电宝用来给手机冲电。
本实施例的一体式自开自闭爬楼梯拉杆箱中，滑板4采用瓦楞结构。瓦楞结构是由许许多多的小拱形组成，小拱形能把受到的力向下、向左右方向分解传递，由于采用了瓦楞结构，提高了滑板4的抗弯曲和冲击能力，本实施中的滑板4厚度为2毫米左右，大大的减轻了滑板重量和成本，但不限于此，实际厚度可以根据客户需求进行调节。
本实施例的一体式自开自闭爬楼梯拉杆箱中，所述滑板4的左右两侧均设置有拱形凸块401。两个拱形凸块401比中间的小拱形略高，减少阻力，滑行起来更顺畅，还可以防止滑板4中间接触障碍物，避免刮花滑板4后，要整体更换滑板4，还可在滑板4两边的拱形凸块401上安装可拆卸耐磨条402，而无需更换整块滑板4，仅需更换可拆卸耐磨条402即可。滑板4设计成直通型或弧形。滑板4的材质可用四氟乙烯、upe、尼龙等耐磨又摩擦系数低的材质。
本实施例的一体式自开自闭爬楼梯拉杆箱中，所述滑板4的顶部设置有缓冲海绵17，爬楼梯的过程中，滑板4顶部会和箱体1相碰，缓冲海绵17隔在滑板与箱体之间起到缓冲减震的作用；内托18的底部也设置有缓冲海绵17，也是为了缓冲扭簧连杆9对内托18的冲击力，吸收动能、减少噪音。
使用方法：
爬楼梯时，利用重心和受力点的转移自动控制滑板4的开、合。拖着拉杆箱上楼梯时，拉杆箱受力点从单向轮5上，瞬间转移到了滑板4前端，在拉杆箱的重力冲击下，滑板4朝里朝下运动卸力(图4)，这时滑板4的两侧边进入槽口20，只有滑板4的顶部缓冲海绵17和箱体1的后幅接触，缓冲海绵17压缩缓解冲击。爬完一个台阶，拉杆箱受力点又从滑板4前端，转移到单向轮5上，在拉杆箱的重力和向前的拉力下，滑板4自动打开，滑板4顶端开始接触第二级台阶(图5)，往复循环。每爬一级台阶，滑板4就自动开合一次，类似玩跷 跷板，这种独特的减震方式，大大的缓解了台阶对拉杆箱的冲击力。下楼梯时，拉杆箱在前、人在后推着下楼，减震方式一样。
平地行走时，把拉杆箱直立起来，拉杆箱的受力点从单向轮5转移到四个万向轮3上，在拉簧和扭簧的作用力下，滑板4向上运动，回到常闭状态。这时拉杆箱就可以水平方向推着走(图7)，也可以拉着走(图6)。在平路拉着走，滑板4是不会打开的，因为这时拉杆箱的受力点在单向轮5的底部，滑板4受到的是一个朝上的作用力，2个限位连杆8的顶部抵接内托18的顶部，滑板4也不会继续朝上运动，使滑板4相对于箱体1处于关闭状态。只有受力点在单向轮5的顶部以上，滑板4受到外力作用下，滑板4才会打开，也就是说地面必须要有高低差。比如遇到台阶、坑洞等复杂路况，滑板4就会自动打开，帮助人们快速越过障碍。
实施例二
如图11所示，本实施例与实施例一不同点在于，本发明中拱形凸块401上设计一个可插入滑条404的滑槽403，这样就可以定期抽出滑条404并进行更换，操作更加简便、效率。
显然，上述为本发明一体式自开自闭爬楼梯拉杆箱的实施例，上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本发明的技术方案所引伸出的显而易见 的变化或变动仍处于本发明的保护范围之列。
