Description

一种冰箱门体助吸器
技术领域
本发明涉及 冰箱门体技术 领域，更具体地，涉及一种冰箱门体助吸器。
背景技术
冰箱在开关门时往往会存在用力较小会关不紧门，或者用力较大门体回弹以致关不紧门的现象，一旦冰箱门关不紧不仅会造成用电的浪费更会造成箱体内冷气外漏，箱体内部温度升高从而导致内部食物的腐坏、变质。
冰箱的开关门运动一般为设于门体的助吸器完成，该助吸器设置于冰箱铰链处，传统的助吸器为尼龙材料，关门时的回弹力来自尼龙的变形，该回弹力小，从而产生的关门力小；从设计角度出发，这种助吸器的回弹力往往需要经过多次计算和验证，所需时间和成本较高，同时传统助吸器设计与门体的下方，影响外形的美观。
实用新型内容
本发明为克服上述现有技术所述的至少一种缺陷，提供一种 冰箱门体助吸器，助吸器的旋转锁紧结构具有关门时锁紧门体的自锁功能，且关门可靠。
为解决上述技术问题，本发明采用的技术方案是：
提供 一种冰箱门体助吸器，包括门端盖、盖板和铰链，铰链分别连接冰箱的箱体和门体，所述门端盖与门体固定连接，所述助吸器还包括转轴和弹片，所述转轴与铰链连接，所述弹片通过固定连接结构与门端盖连接，弹片上设有第一止挡结构，转轴上设有凸起结构；
当门体与箱体为一定夹角时，所述转轴顶压弹片使其产生变形，夹角继续减小，弹片回弹，转轴的凸起结构落入第一止挡结构，迫使转轴与弹片锁紧，实现门体的锁紧。
关门时铰链轴的旋转带动转轴旋转，弹片通过固定连接结构与门端盖连接，从而相对门体固定，转轴旋转至门体与箱体为一定夹角时，转轴的凸起结构压迫弹簧使其产生变形，当夹角继续减小到时，弹片的回弹作用使得凸起落入第一止挡机构中达到转轴与弹片的锁紧即门体与箱体的锁紧。
作为优选的，所述转轴上设有的凸起结构为圆滑的长条形凸起，该凸起结构截面为 U 型，弹片上设有的第一止挡槽为 U 型止挡槽， U 型凸起置于 U 型止挡槽内起到了自锁的作用；施力旋转铰链轴时可带动转轴旋转，门体与箱体夹角增大到一定角度，弹片受力变形，该 U 型凸起旋转至 U 型挡槽的外侧即完成开启冰箱门体的运动，反之，施力旋转铰链轴带动转轴旋转，门体与箱体夹角减小到一定角度，弹片受力变形， U 型凸起滑入 U 型当槽中，门体与箱体关闭，完成 U 型槽的自锁。
作为优选的，所述铰链上设有铰链轴，所述转轴上设有第一通孔，所述铰链轴置于第一通孔内；
进一步的，所述铰链轴的截面为 D 型，所述第一通孔为 D 型孔，所述铰链轴置于第一通孔内， D 型轴插入 D 型孔达到孔与轴的相对固定连接，从而达到铰链与转轴的相对固定，转动铰链即可由该固定连接结构带动转轴的旋转。
作为优选的，所述固定连接结构包括设于弹片上的第二止挡槽和设于门端盖上的卡槽，该卡槽上设有挡筋和加强筋，所述弹片的一侧置于卡槽内，所述挡筋置于第二止挡槽内，加强筋置于第二止挡槽外侧；所述第二止挡槽为 U 型止挡槽，所述挡筋为球形挡筋，所述加强筋为中空的加强筋；该卡槽结构连同挡筋和加强筋结构将弹片处于夹紧状态，使弹片与门端盖相对固定，第二止挡槽起到了限位卡紧的作用。
作为优选的，所述门端盖与冰箱门体是一体的结构，所述门端盖内部设有第二通孔，所述第二通孔外侧设有第一盖沿，所述盖板内部设有的盲孔，所述盲孔外部设有第二盖沿，所述转轴的一端置于第二通孔内，另一端置于盲孔内，且第二盖沿的外侧卡合于第一凸盖沿的内侧；由于弹片是与转轴上凸起结构相连接的，弹片置于门端盖内，同时铰链结构连接门体与箱体，且铰链轴与转轴相固定连接，从而铰链轴是通过门端盖的第二通孔达到与转轴相固定连接，继而延伸至盖板处与盖板内部盲孔相配合，即整个助吸器的外部结构为闭合的盖板和门端盖组成，铰链轴穿过门端盖与助吸器内部结构相连接，达到冰箱门体助吸器整体外观上简洁、美观的目的。
与现有技术相比，本发明的有益效果是：
本发明冰箱门体助吸器的第一固定连接结构、第二固定连接结构和旋转锁紧结构通过铰链轴的旋转在开启冰箱门时对弹片施力产生变形，使转轴上的 U 型凸起转出 U 型挡槽，实现冰箱的开启操作；在关闭冰箱门时对弹片施力，使转轴上的 U 型凸起转入 U 型当槽中实现自动锁紧，消除了因回弹力较小造成冰箱门体关闭不紧带来的弊端，自锁能力好；同时冰箱门体助吸器的外部结构由门端盖和盖板相互卡合而起到了遮挡内部结构的作用，助吸器的整体置于门体内部，整体结构的简洁和美观。

如图 3 所示，所述铰链 5 的铰链轴 51 插入转轴 2 的第一通孔 21 中，由于铰链轴 51 的横截面为 D 型，第一通孔 21 为 D 型，此结构可以使两者相对固定连接；所述固定连接结构为弹片 3 的一端置于门端盖 1 的卡槽 11 内，并由所述挡筋 111 和加强筋 112 相对卡紧，且加强筋 111 置于弹片 3 的第二止挡槽 32 内侧，所述加强筋 112 置于第二止挡槽 32 外侧，所述挡筋 111 为球形，所述加强筋 112 为中空的加强筋，所述第二止挡槽 32 为 U 型止挡槽，所述挡槽内部挡筋 111 和外部加强筋 112 的夹紧和卡槽 11 的夹紧作用使得弹片 3 与门端盖固定连接；转轴 2 上的凸起结构 21 置于弹片 3 上的第一止挡槽中，所述凸起结构 21 为 U 型结构，所述第一止挡槽为 U 型止挡槽，两者旋转锁紧。
如图 4 所示，施力关闭冰箱门体时，门体和箱体相对旋转，即铰链轴 51 旋转，带动转轴 2 旋转，当门体与箱体夹角小于 55 度时，转轴 2 上的凸起结构 21 顶压弹片 3 使其产生变形，当夹角小于 22 度时，弹片 3 回弹，回弹力迫使转轴 2 上的凸起结构 21 落入弹片 3 上的第一止挡槽 31 内，达到自动锁紧，弹片 3 通过固定连接结构与门端盖 1 固定连接，从而使得冰箱门体与箱体达到锁紧状态。
