一种铰链结构、卧式冷柜和工作方法 技术领域
本发明涉及制冷设备技术领域，特别涉及一种铰链结构、卧式冷柜和工作方法。
 背景技术
制冷器具门体开启过程中，都需要与箱体进行连接，尤其对于卧式制冷器具而言，箱盖与箱体之间用铰链部件进行活动连接，进而使箱盖部件进行旋转开门。传统铰链利用弹簧提供弹力，利用铰链头旋转来运动，导致铰链的整体厚度较大，不利于安装和空间利用。

附图标记包括：1-弹簧、2-弹簧杆、3-支撑座、4-长条孔、5-滚轴、6-铰链头、7-铰链头上轴、8-铰链头下轴、9-凸轮件、10-滚轴架、11-铰链座、12-凸缘。
 本发明的实施方式
下面结合具体实施例对本发明的具体实施方式做进一步说明：
一种铰链结构，包括铰链座11、铰链头6和凸轮件9，铰链头6铰连接在所述铰链座11的顶部，铰链头6的两侧和铰链座11的两侧均向各自的背面延伸形成侧板，所述凸轮件9设在铰链头6的两个侧板之间，铰链座11的两个侧板之间设有可上下滑动的滚轴5，所述滚轴5与凸轮件9底部的凸缘12触碰，滚轴5底部通过滚轴架10连接弹簧杆2的顶部，弹簧杆2的底部固定在铰链座11底部的支撑座3上；
所述凸缘12由凸轮件9的底部向下延伸，凸轮件9竖直时，所述凸缘12处在滚轴5的后侧，铰链头6的顶部向后侧旋转时，凸缘12由滚轴5的后侧转至滚轴5的顶部，然后到达滚轴5的前侧。
所述凸轮件9通过铰链头上轴7和铰链头下轴8固定在铰链头6的两个侧板之间。
所述铰链头6通过铰链头上轴7铰连接铰链座11，所述铰链头上轴7穿过铰链座11顶部的轴孔。
所述轴孔底部设有沿铰链座11长度延伸的长条孔4，所述滚轴5设在所述长条孔4中。
所述滚轴架10通过其顶部的滚轴5孔连接所述滚轴5。
沿弹簧杆2的长度方向设有弹簧1，所述弹簧1盘绕在弹簧杆2上。
所述凸轮件9竖直时，所述弹簧1处在压缩状态。
一种卧式冷柜，使用所述的一种铰链结构，包括门体和箱体，所述铰链头6的正面固定在门体的后侧，铰链座11的正面固定在箱体的后侧。
一种卧式冷柜的工作方法，使用所述的一种卧式冷柜，包括：开门时，使用者抬起门体，此时门体前端向上运动，门体的后侧的顶部也向上向后旋转，带动铰链头6一起转动，此时铰链头6顶部向后旋转，底部向前旋转，带动固定在铰链头6上的凸轮件9也旋转，使凸缘12向前运动，越过滚轴5的顶部，此时弹簧1解除压缩状态，门体不会自动关闭；
关门时，使用者关闭门体，此时门体前端向下运动，门体的后侧的顶部也向下向前旋转，带动铰链头6一起转动，此时铰链头6顶部向前旋转，底部向后旋转，带动固定在铰链头6上的凸轮件9也旋转，使凸缘12向后运动，此时凸缘12会将滚轴5向下挤，将弹簧1由不压缩状态挤压为压缩状态，同时凸缘12会越过滚轴5的顶部，即凸轮结构的平衡点，到达滚轴5的后侧，此时门体已经完全关闭，由于弹簧1为压缩状态，会将滚轴5向上挤，滚轴5顶在所述凸缘12上，使门体紧紧关闭。
具体设置时，凸缘12应向后侧倾斜，确保凸轮件9竖直时，凸缘12处在滚轴5后侧，但凸缘12的顶点向凸轮件9前侧延伸的面应设为曲面，使凸缘12向前移动，挤压滚轴5时，其相对摩擦的面均为曲面，防止损坏设备。关门时弹簧力的大小，可由弹簧1的选材决定。当凸缘12向前移动，越过滚轴5顶部时，继续向前就会解除弹簧1的压缩状态，如果再配合具备阻尼能力的铰链，则可以实现门体的悬停能力，但当门体即将关闭时，弹簧1的弹力会使门体紧紧闭合。
当然，上述说明并非是对本发明的限制，本发明也并不仅限于上述举例，本技术领域的技术人员在本发明的实质范围内所做出的变化、改型、添加或替换，也应属于本发明的保护范围。
