请参阅图1至图3，本发明较佳实施方式的具有缓冲效果的铰链10包括第一组件12、第二组件14、主弹簧16、连接片18、阻尼器组件20及连接组件22。第一组件12及第二组件14分别用于固定本体及下拉门且通过第一转轴142转动连接从而使得下拉门可相对于本体转动下拉，第一组件12呈矩形壳体并包括与第二组件14转动连接的第一端120及相对的第二端122，第一组件12开设有导槽124，第二组件14形成有凸轮部140。主弹簧16设置于第一组件12内，主弹簧16的一端与第二端122固定连接。连接片18设置于第一组件12内，连接片18的一端通过第二转轴24与第二组件14转动连接，连接片18的另一端通过第三转轴26与主弹簧16的另一端连接，第三转轴26可转动且可滑动设置在导槽124内，连接片18形成有第一上盖180以与第一组件12配合形成有腔室182。阻尼器组件20包括阻尼器主体200、伸缩杆202、限位片204及固定组件206。阻尼器主体200位于腔室182内。伸缩杆202从阻尼器主体200向第二组件14延伸。限位片204设于伸缩杆202的顶端。固定组件206可将阻尼器主体200固定于第一组件12上。连接组件22设置于第二组件14与伸缩杆202之间，连接组件22包括从动轮220及锁紧弹簧222，从动轮220可与凸轮部140接触。连接组件22与限位片204之间连接片18设有连接轴28，连接轴28可在连接片18的带动下与限位片204接触以推动限位片204向主弹簧16方向运动。第二组件14自与第一组件12成最大张角处向第一组件12转动过程中依次包括平衡段、临界段及缓关段。在平衡段中，主弹簧16处于拉伸状态，主弹簧16产生的拉紧力与铰链10的负载重量相平衡。在临界段中，锁紧弹簧222处于压缩状态，连接轴28接触限位片204以向主弹簧16方向推 动阻尼器主体200，主弹簧16处于拉伸状态，主弹簧16产生的拉紧力大于铰链10的负载重量。在缓关段中，锁紧弹簧222处于压缩状态，伸缩杆202向阻尼器主体200内压缩，阻尼器主体200产生反向缓冲作用力，主弹簧16处于拉伸状态，主弹簧16产生的拉紧力大于铰链10的负载重量。
本发明较佳实施方式的铰链，由于采用主弹簧16，在下拉下拉门时能平衡下拉门的重量，达到稳开稳合的效果。另外，由于采用阻尼器组件20，能达到使下拉门自动缓慢关闭的效果，能提高用户的使用体验。
具体地，第一组件12内收容有主弹簧16、连接片18、阻尼器组件20及连接组件22。第一组件12在靠近第一端120的底板126开设有平行于第一组件12的轴向的凹槽128。在第一端120处第一组件12与第二组件14通过第一转轴142连接，第一组件12可绕第一转轴142相对于第二组件14转动且同步带动连接片18运动，第二组件14可相对于第一组件12在凹槽128内摆动。在第二端122处，第一组件12连接有与第一转轴142平行的第四转轴30，远离第一端120的连接片18的末端连接有与第四转轴30平行的第三转轴26，主弹簧16与第三转轴26及第四转轴30连接。其中，连接片18为一体成型。
在本实施方式中，第一组件12基本呈矩形，第一组件12包括第一端120及与第一端120相对的第二端122，第一组件12包括底板126及自底板126两侧向上延伸的侧壁128a，导槽124开设于两侧壁128a上。导槽124包括第一端点1240及与第一端点1240相对的第二端点1242。第二组件14与第一组件12通过第一转轴142转动连接，第二组件与连接片18通过第二转轴24转动连接，第二转轴24与第一转轴142平行。第一组件12收容有连接片18，连接片18紧贴第一组件12的两侧壁128a，连接片18形成有第一上盖180以与第一组件12配合形成有腔室182，阻尼器主体200位于腔室182内。连接片18还形成第二上盖184，连接组件22位于第二上盖184的下方。第二组件14呈片状且插入凹槽128。连接片18连接主弹簧16与第二组件14，连接片18与第二组件14的连接点偏离第二组件14的第一转轴142以使第二组件14相对于第一组件12转动时带动连接片18移动从而拉伸主弹簧16。
在本实施方式中，固定组件206包括自底板126向上凸起的矩形凸块2060及连接阻尼器主体200与第一组件12的定位销2062，凸块2060可卡住阻尼器主体200以阻挡阻尼器主体200向第二组件14方向滑动。
如此，采用固定组件206能对阻尼器主体200进行定位，且结构简单，安装、拆卸 方便。
在本实施方式中，腔室182呈矩形，阻尼器主体200呈圆柱形，阻尼器主体200与腔室182的形状配合。其中，阻尼器主体200内有复位弹簧。
在本实施方式中，连接组件22包括连接体224、套设在连接体224上的锁紧弹簧222及设置在连接体224上的从动轮220，连接体224上形成有固定轴2240，从动轮220呈圆环状且套设在固定轴2240中，从动轮220可与凸轮部140转动接触。其中，凸轮部140具有与从动轮220做多种接触的凹进和凸出的部分。
如此，由于第一组件12与第二组件14之间夹角越小，主弹簧16的拉紧力越弱，通过连接组件22上的锁紧弹簧222进行拉力补充，连接组件22上的从动轮220与第二组件14的凸轮部140接触，从而得到一个动力源。
在本实施方式中，连接组件22与连接轴28之间设有固定于第一组件12的卡件32，卡件32可卡住锁紧弹簧222以压缩锁紧弹簧222。
第一组件12设置在下拉门上，第二组件14设置在本体上，铰链10工作时，第二组件14的位置恒定不变，第一组件12能以第一转轴142为轴进行一定角度的旋转，同步带动连接在第二组件14上的连接片18运动，从而能拉伸连接在连接片18上主弹簧16，在主弹簧16和阻尼器组件20的作用下，下拉门可以实现自动缓慢关门的效果。
具体地，铰链10从n1到n2为平衡段，从n2到n3为临界段，从n3到n4为缓关段。当第二组件14相对于第一组件12处于n1位置时，铰链10的张角达到最大，下拉门打开的角度达到最大。当第二组件14相对于第一组件12处于n4位置时，铰链10的张角达到最小，门体处于闭合状态。
当第二组件14相对于第一组件12处于n1位置时，连接片18带动第三转轴26到达第一端点1240，连接片18拉伸主弹簧16使得主弹簧16处于拉伸状态，主弹簧16的拉紧力与铰链10的负载重量相平衡。当铰链10处于a角度内，即铰链10从n1到n2的平衡段内，由于主弹簧16的拉紧力与铰链10的负载重量相平衡，下拉门可在该范围内任意位置静止不动，此时关闭下拉门需要人为外力。
当第二组件14相对于第一组件12处于n2位置时，主弹簧16的拉紧力大于铰链10的负载重量，连接轴28与限位片204接触，连接组件22的从动轮220与凸轮部140接触。当铰链10处于b角度时，即铰链10从n2到n3的临界段内，与主弹簧16连接的连接片18向主弹簧16的方向滑动，连接轴28将阻尼器主体200向主弹簧16的方向推动，即铰链10能自动带动下拉门朝关闭方向快速转动，此时下拉门可自动关闭，无 须外力。
当第二组件14相对于第一组件12处于n3位置时，主弹簧16的拉紧力大于铰链10的负载重量，第三转轴26位于第二端点1242。当铰链10处于c角度时，即铰链10从n3到n4的缓关段，主弹簧16的拉紧力使得第二组件14继续向n4位置旋转，伸缩杆202开始向阻尼器主体200内压缩，阻尼器主体200产生反向缓冲作用力，减缓铰链10带动门体转动的速度，下拉门以缓慢且均匀的速度旋转，此时能实现下拉门自动关闭同时不快速弹回，而是平缓关闭。
当第二组件14相对于第一组件12处于n4位置时，铰链10的张角达到最小，门体处于闭合状态。此时，主弹簧16、锁紧弹簧222及复位弹簧均处于自然状态。
当铰链10因外力作用(通常为人为施加的力)由n4位置打开到c角度的范围内的任意位置，阻尼器主体200向第二组件14方向滑动，复位弹簧会给阻尼器主体200一个阻力使阻尼器主体200内的液压油复位，撤销外力后，由于主弹簧16的拉紧力大于铰链10的负载重量，下拉门会向主弹簧16的方向旋转，即下拉门仍会以缓慢且均匀的速度关闭，即铰链10仍会回到n4位置。
下拉门在打开的过程中，即铰链10从n4位置转动到n1位置的过程中，主弹簧16由初始状态拉伸，锁紧弹簧222压缩，由于伸缩杆202带动阻尼器主体200向第二组件14的方向滑动，复位弹簧使得阻尼器主体200复位，复位弹簧也恢复到自然状态。
在本实施方式中，对应平衡段，铰链10处于n1-n2的位置，此时主弹簧16产生的拉紧力与铰链10的负载重量相平衡，下拉门可在a角度范围内的任意位置停顿。其中，对应平衡段下拉门可转动的范围为50°-70°，即a角度的范围可为50°-70°。
在本实施方式中，对应临界段，铰链10处于n2-n3的位置，此时主弹簧16产生的拉紧力大于铰链10的负载重量，铰链可在b角度范围内由n2位置快速转动到n3位置。其中，对应临界段下拉门可转动的范围为10°-15°，即b角度的范围可为10°-15°。
在本实施方式中，对应缓关段，铰链10处于n3-n4的位置，此时主弹簧16产生的拉紧力大于铰链10的负载重量，铰链可在c角度范围内由n3位置缓慢转动到n4位置。其中，对应缓关段下拉门可转动的范围为10°-25°，即c角度的范围可为10°-25°。
如此，能达到使所述下拉门在设计角度范围内自动缓慢关闭的效果，能提高用户的使用体验。
当然，以上数值仅作为例子给出帮助说明铰链10如何实现下拉门在一定开合角度内实现自动缓慢关门的方式，并不用于限制本发明。
本发明较佳实施方式的装置包括本体及下拉门，装置包括上述铰链10，其中，第一组件12固定设置在下拉门上，第二组件14固定设置在本体上。可选地，装置为烤箱。当然，烤箱仅作为一个例子，并不用于限制本发明。如此，可以实现装置的下拉门自动缓慢关闭的效果，能避免装置的下拉门由于用力过度快速闭合从而造成的损坏。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施方式，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
