以下将结合附图所示的具体实施例对本发明进行详细描述。
在本发明的各个图示中，为了便于图示，结构或部分的某些尺寸会相对于其它 结构或部分扩大，因此，仅用于图示本发明的主题的基本结构。

参看图1至图3，本发明一实施例提供的制冷设备100，包括铰链1、柜体2和门体3，柜体2具有用于储存和冷藏物品的制冷间室，门体3组装于柜体2并可通过铰链1相对柜体2转动以打开或关闭所述制冷间室。制冷设备100具体可设为冰箱、冷柜、酒柜等。
结合图3至图8，铰链1包括定铰链座11以及与定铰链座11转动连接的动铰链座12，定铰链座11包括枢转轴113，动铰链座12与枢转轴113转动连接从而使动铰链座12相对于定铰链座11转动，其中，定铰链座11装配于柜体2，动铰链座12装配于门体3，通过动铰链座12相对定铰链座11转动从而带动门体3相对柜体2转动以打开或关闭所述制冷间室。
定铰链座11包括贴靠柜体2外壁的底板111以及相对设置的一对侧板112，底板111具有第一端1111以及与第一端1111沿第一方向相对设置的第二端1112，一对侧板112分别连接于底板111沿垂直于所述第一方向的第二方向的相对两端，一对侧板112设置于底板111的同一侧，一对侧板112与底板111之间形成装配空间。优选地，一对侧板112沿背离底板111的方向垂直基板121延伸。
枢转轴113的两端分别连接一对侧板112，且枢转轴113的轴线沿所述第二方向延伸。
动铰链座12包括贴靠门体3的基板121以及沿所述第二方向相对设置的一对侧边122，一对侧边122分别连接于基板121沿所述第二方向的相对两端，一对侧边122相对设置于基板121的同一侧，一对侧边122设于一对侧板112之间并与一对侧板112一一对应，一对侧边122分别枢转连接于枢转轴113并可使动铰链座12绕枢转轴113相对底板111转动。
进一步地，侧边122平行于侧板112。优选地，侧边122沿远离门体3的方向垂直基板121延伸，侧板112沿背离柜体2侧壁的方向垂直底板111延伸。
为便于描述，在本实施例中，以制冷设备100水平放置于地面上为例展开描述，在门体3关闭的状态下，定义自门体3向柜体2的方向为自上至下的方向，对应地，动铰链座12位于定铰链座11的上方，定义铰链1朝向所述制冷设备100的一侧为内，定义铰链1背离制冷设备100的一侧为外，以使用者自外侧面对铰链1时，铰 链1的两侧分别定义为左和右。
则在本实施例中，所述第一方向为上下方向，所述第二方向为左右方向，定铰链座11包括上下延伸的底板111以及左右相对设置的一对侧板112，一对侧板112分别连接于底板111的左右两端且垂直于底板111向外延伸；枢转轴113沿左右方向延伸；动铰链座12包括贴靠门体3的基板121以及左右相对设置的一对侧边122，基板121可绕左右方向相对底板111转动，一对侧边122分别连接于基板121的左右两端且垂直于基板121向外延伸。
动铰链座12具有打开门体3的开门位置和关闭门体3的初始位置，图4示出了动铰链座12于初始位置的状态，图9示出了动铰链座12于开门位置的状态。此处的开门位置定义为门体3打开至设定的最大角度时动铰链座12相对定铰链座11的位置，所述最大角度通常设置为门体3翻转打开81°～88°。
参看图4，进一步地，铰链1还包括设于定铰链座11的止动件13，止动件13位于动铰链座12朝向所述装配空间转动的路径上，止动件13可抵持动铰链座12以限制动铰链座12相对定铰链座11转动的角度，从而限制门体3相对柜体2打开的最大角度。
于所述初始位置时，基板121也沿上下方向延伸，也即基板121与底板111平行或者共面，动铰链座12相对定铰链座11自所述初始位置打开至所述开门位置的过程中，动铰链座12绕枢转轴113朝向所述装配空间转动，也即向外转动，至止动件13抵持动铰链座12时，动铰链座12于所述开门位置，止动件13限制动铰链座12继续朝向所述装配空间转动，从而使门体3悬停。通过设置止动件13来限制动铰链座12相对定铰链座11转动的角度，从而限制门体3的开门角度并使门体3在打开所述开门角度后悬停。
参看图4，具体地，止动件13设于侧板112并自侧板112朝向所述装配空间内凸伸，止动件13位于与其所在的侧板112相对应的侧边122朝向所述装配空间转动的路径上，动铰链座12绕枢转轴113向外转动至止动件13抵持侧板112时，侧板112可限制动铰链座12继续向外转动。
优选地，止动件13设于侧板112远离底板111的一端，这样，可以防止止动件13对动铰链座12带动门体3打开造成影响。
具体地，在本实施例中，止动件13为平行于底板111的板状件，一方面可以进一步避免止动件13对动铰链座12带动门体3打开造成影响，另一方面，可以保证止动件13的强度，由于制冷设备100的门体3重力较大，因此需要止动件13具有 足够的承压能力以免失效损坏，影响铰链1和制冷设备100的寿命。
优选地，止动件13与侧板112一体设置，可以进一步提高止动件13与侧板112的连接强度。
优选地，止动件13设置有两个，两个止动件13分别设于一对侧板112并朝向彼此凸伸，每个止动件13位于与其所在的侧板112相对应的侧边122朝向装配空间转动的路径上，从而可以分担来自门体3的压力，进一步提高止动件13的承压能力。
进一步地，铰链1还包括连接件14和滑动机构15，动铰链座12还包括摆动轴123，摆动轴123平行于枢转轴113，连接件14与摆动轴123枢转连接从而实现连接件14与动铰链座12的枢转连接，定铰链座11开设有上下延伸的限位槽124，滑动机构15包括活动轴151以及配接于限位槽124中的配接部152，活动轴151平行于枢转轴113，配接部152可沿限位槽124的延伸方向做直线运动，从而使滑动机构15沿限位槽124的延伸方向做直线运动，连接件14的上端转动连接摆动轴123，连接件14的下端枢转连接活动轴151，从而使连接件14转动连接动铰链座12和所述滑动机构15并带动配接部152沿限位槽124的延伸方向做直线运动。
参看图4，在本实施例中，限位槽124设置于侧板112，优选地，限位槽124设置有一对，且一对限位槽124左右相对分别设置于一对侧板112，而配接部152为活动轴151的轴向两端，也即活动轴151的轴向两端分别配接于一对限位槽124中。
参看图5至图6，在其它实施例中，限位槽124也可以设置于底板111，配接部152与活动轴151连接并朝向底板111凸伸。
参看图7至图8，进一步地，铰链1还包括限位块16，限位块16可拆卸组装于限位槽124中，限位块16具有装配于限位槽124中的组装状态、以及与限位槽124分离的自由状态。限位块16于所述组装状态时，限位块16抵持活动轴151以限制活动轴151沿限位槽124运动。限位块16于所述自由状态时，连接件14可带动活动轴151沿所述限位槽124做直线运动。
这样，在铰链1的运输过程中，或者将铰链1装配于制冷设备100时，可以将限位块16装配于限位槽124中，从而防止定铰链座11相对动铰链座12来回翻转而对铰链1造成损坏；另外，现场工人在安装时，通过将限位块16装配于限位槽124中即可防止动铰链座12来回翻转，而不需要用手扶住动铰链座12便可使动铰链座12固定贴合于门体3以便于安装，大大提高了安装效率，降低了人工成本。当安装完成后，即可将限位块16自限位槽124中取下，使限位块16与限位槽124分离，从而可使动铰链座12相对定铰链座11转动。
具体地，限位槽124具有极限近端1241以及沿所述第一方向与极限近端1241相对设置的极限远端1242。限位块16于所述组装状态时，动铰链座12于所述初始位置，限位块16的一端抵持极限近端1241，限位块16的另一端抵持活动轴151并使活动轴151抵持极限远端1242。
优选地，限位块16于所述组装状态时，限位块16抵持活动轴151的一端具有弧形凹槽，活动轴151卡接于所述弧形凹槽中，从而使限位块16与活动轴151的配合更紧密，防止动铰链座12相对定铰链座11翻转。
优选地，限位槽124于所述极限近端1241的槽壁呈圆弧状，限位块16于所述组装状态时，限位块16抵持所述极限近端1241的一端也呈圆弧状并贴合限位槽124于所述极限近端1241的槽壁，从而使限位块16与限位槽124的配合更紧密，以进一步防止动铰链座12相对定铰链座11翻转。
进一步地，限位块16也设置有两个，且两个限位块16与一对限位槽124一一对应，以使两个限位槽124均匀受力，从而使铰链1的左右两端受力平衡。
优选地，每个限位槽124沿左右方向贯通其所在的侧板112，以便于活动轴151的装配，还可以提高活动轴151与限位槽124的槽壁的接触面积，提高活动轴151沿限位槽124运动的稳定性。
进一步地，限位块16沿左右方向的厚度大于限位槽124沿左右方向的深度，从而提高限位块16装配于限位槽124时的稳定性，避免其在使用过程中脱落。
进一步地，限位块16于所述组装状态时，限位块16沿第三方向的两端分别贴合限位槽124沿所述第三方向的两端的槽壁，其中，所述第三方向垂直于所述第一方向和所述第二方向，也就是说，在本实施例中，所述第三方向为自内向外的方向。
参看图3至图4以及图7至图8，进一步地，铰链1还包括弹性件17，弹性件17位于所述装配空间中，弹性件17的一端与活动轴151连接，且弹性件17与活动轴151同步运动，弹性件17的另一端抵持定铰链座11，动铰链座12于所述开门位置和所述初始位置之间运动时，弹性件17始终处于压缩状态。这样，动铰链座12绕枢转轴113相对定铰链座11转动时，摆动轴123随之摆动并牵引连接件14带动活动轴151一并运动，而且运动过程中在各个部件的相互限制下，摆动轴123、活动轴151与枢转轴113三者始终处于平行状态，而动铰链座12、枢转轴113、摆动轴123、连接件14、活动轴151、弹性件17和定铰链座11共同构成了曲柄滑块机构，将动铰链座12的枢转运动转化为活动轴151和弹性件17的直线运动，相较于活动轴151和弹性件17做弧线运动，大大减少了弹性件17运动所需要的活动空间，尤 其是在内外方向上，因此可将铰链1的厚度做薄。
在本实施例中，弹性件17设置有一个；在其它实施例中，弹性件17也可以设置多个以分担受力，多个弹性件17间隔排布，例如图12至图13所示，弹性件17设置有两个，且两个弹性件17间隔设置于连接件14的两侧，从而可分担压力，进而使每个弹性件尺寸做小，进一步减小铰链1的厚度。
实际应用中，在外力的作用下将门体3打开至侧边122抵持止动件13时，门体3打开至设定的最大开门角度，当撤去外力后，在门体3自身重力的作用下，由于枢转轴113、摆动轴123和与其转动配接的各个部件之间不可避免地存在配合间隙，门体3会有一定角度的回弹，使侧边122远离止动件13一段距离，门体3难以在设定的最大开门角度悬停。
为解决上述技术问题，动铰链座12相对定铰链座11向外转动至所述开门位置时，使活动轴151与限位槽124的极限近端1241之间具有间隙，且弹性件17具有压缩形变量。这样，施加外力使动铰链座12随门体3转动至所述开门位置时，由于所述间隙的存在，弹性件17在其弹性回复力的作用下，对连接件14施加向上的推力，传导至摆动轴123形成连接件14对摆动轴123向上的推力，从而使动铰链座12具有绕枢转轴113向外转动的趋势，即使撤去外力后该推力也可与门体3重力形成平衡，从而使门体3悬停于设定的最大开门角度处，解决了外力撤去后门体3回弹的问题。
在本实施例中，弹性件17设置有一个；在其它实施例中，弹性件17也可以根据实际需要设置多个。例如，弹性件17间隔设置有一对，一对弹性件17分别设于连接件14的左右两侧，多个弹性件17可以分担受力，这样弹性件17可以把尺寸做小，如果弹性件17包括弹簧172，则弹簧172的外径和线径都可以减小，从而可以进一步减薄铰链1的厚度。
参看图8，进一步地，弹性件17包括与滑动机构15连接的支撑杆171以及套设于支撑杆171外周的弹簧172，支撑杆171远离滑动机构15的一端插置于定铰链座11中并与定铰链座11松配连接，也就是说支撑杆171可相对定铰链座11上下运动，支撑杆171靠近滑动机构15的一端设置有凸缘1711，弹簧172的一端抵持凸缘1711，弹簧172的另一端抵持定铰链座11。
进一步地，定铰链座11包括设于其远离动铰链座12的一端的端挡114，端挡114的两端分别与一对侧板112连接，端挡114具有插槽，支撑杆171远离滑动机构15的一端插置于所述插槽中从而限定弹性件17只能平行底板111运动，也就是上下 运动，而避免增加铰链1的厚度；在本实施例中，弹簧172的下端抵持端挡114，支撑杆171与端挡114松配连接，且弹性件17随活动轴151同步上下运动时，支撑杆171的下端始终凸伸出端挡114，这样可防止弹性件17脱出端挡114而使铰链1失效。
参看图4和图8，进一步地，铰链1还包括轴套18，轴套18套设于摆动轴123和活动轴151二者至少其一的外周，轴套18包括套筒181以及设于套筒181内壁的储油筋182，这样，可以在储油筋182之间加润滑油，润滑油可以自轴套18中慢慢渗出至摆动轴123、活动轴151，从而起到对摆动轴123、活动轴151的润滑保护作用，使铰链1转动顺畅，减少使用过程中的磨损和噪音，延长铰链1和制冷设备100的使用寿命，改善用户的使用体验。
其中，套筒181可以设置呈圆筒状。参看图10至图11，优选地，设置套筒181的横截面呈圆弧状，且其圆心角为270～280°。这样，通过将套筒181设置呈半封闭式的开口结构，可以沿径向直接将轴套18卡接到摆动轴123、活动轴151上，不仅提高了装配效率，而且不受装配顺序的限制，避免了装配顺序错误时将各部件全部拆掉重装的麻烦。
进一步地，储油筋182沿套筒181的轴向延伸，储油筋182设置有至少两根，且至少两根储油筋182沿套筒181的周向均匀排布，均可延缓润滑油自轴套18渗出的速率，避免润滑油溢出过多造成铰链1脏污以及需要频繁添加润滑油的问题。
进一步地，连接件14包括与活动轴151连接的一对第一连接端141，活动轴151的外周套设有轴套18，轴套18位于一对第一连接端141之间，且轴套18的轴向两端分别抵持一对第一连接端141，从而限制连接件14沿活动轴151的轴向运动。
参看图8，弹性件17包括与活动轴151连接的配接端173，这里，可将套设于活动轴151外周的轴套18分成两个子轴套，配接端173位于两个子轴套之间并分别抵持两个子轴套，从而限制弹性件17沿活动轴151的轴向运动。
进一步地，也可以在活动轴151位于连接件14和侧板112之间的部分套设轴套18，同样可使每个轴套18的轴向两端分别抵持连接件14以及与该轴套18相邻的侧板112。
同样地，摆动轴123的外周也可以套设轴套18。连接件14包括与摆动轴123连接的一对第二连接端142，具体地，可将轴套18设于一对第二连接端142之间，且轴套18的轴向两端分别抵持一对第二连接端142，以限制连接件14沿摆动轴123的轴向运动；或者，将轴套18设置于第二连接端142和与该第二连接端142对应的侧 边122之间并使二者分别抵持轴套18的轴向两端，以限制连接件14沿摆动轴123的轴向运动。
进一步地，摆动轴123的两端分别连接一对侧边122，且摆动轴123位于一对侧板112之间，也即摆动轴123与定铰链座11无连接，这样的设置取消了现有技术中设于定铰链座11的弧形槽，避免了铰链1受弧形槽的尺寸和承压强度的限制，可以减薄铰链1的厚度，增加储运时制冷设备100的装箱量，减少使用时的占用空间。
在本实施例中，摆动轴123设置有一个；参看图12至图13，在其它实施例中，摆动轴123也可以设置为两个，两个摆动轴123分别与一对第二连接端142连接，且两个摆动轴123同轴设置。
参看图9，进一步地，动铰链座12于所述开门位置时，摆动轴123的轴线位于底板111所在的平面上，或者，摆动轴123的轴线位于底板111所在的平面朝向柜体2的一侧，也即，摆动轴123与活动轴151分别位于底板111的两侧。
结合图6和图8，定铰链座11的一对侧板112的上端凸伸出底板111，而动铰链座12的下端通过枢转轴113连接于一对侧板112的上端，也即，底板111和基板121之间具有一定的距离，从而为摆动轴123和连接件14的摆动提供了空间；门体33于关闭状态时，也即动铰链座12于所述初始位置时，摆动轴123位于枢转轴113的下方。
参看图3，柜体2和门体3之间具有空腔4，且该空腔4位于底板111所在的平面朝向柜体2的一侧，动铰链座12由所述初始位置向所述开门位置转动的过程中，摆动轴123自底板111所在的平面背离柜体2的一侧朝向柜体2摆动至空腔4，也即摆动轴123自外向内摆动至空腔4，而且在此过程中，摆动轴123与制冷设备100的其它结构之间不互相干涉，这样，摆动轴123的摆动不受定铰链座11的限制，其摆动可以借用柜体2和门体3之间的空腔4，使摆动轴123摆动至其轴线位于底板111所在的平面上，或者使摆动轴123摆动至其轴线位于底板111所在的平面背离所述装配空间的一侧，也即朝向柜体2的一侧，从而可以进一步减薄铰链1的厚度，而且不会影响铰链1的强度。
进一步地，动铰链座12由所述初始位置运动至所述开门位置的过程中，也即动铰链座12相对定铰链座11朝向所述装配空间转动的过程中，连接件14与底板111互不干涉。优选地，连接件14与定铰链座11互不干涉。具体地，可以通过设置底板111和基板121之间的距离实现，从而可以使摆动轴123顺利由底板111所在的平面背离柜体2的一侧摆动至空腔4，使得铰链1的厚度可以进一步地做得更薄。
进一步地，连接件14还包括连接第一连接端141和第二连接端142的主体143，第一连接端141通过摆动轴123与动铰链座12转动连接，第二连接端142和滑动机构15连接，主体143朝向远离底板111的方向凹陷。优选地，主体143朝向柜体2的一端远离底板111凹陷，也即朝向远离柜体2的方向凹陷，可以避免连接件14和底板111之间发生干涉，从而可以使摆动轴123顺利向空腔4中摆动，甚至使摆动轴123向空腔4中摆动的幅度更大。
进一步地，枢转轴113与活动轴151的轴线所形成的平面与底板111平行，也可以减小铰链1的厚度。
参看图3，进一步地，动铰链座12于所述初始位置时，摆动轴123的轴线位于活动轴151与枢转轴113的轴线所形成的平面上，这样设置不仅可以将铰链1的厚度做薄，进一步增大制冷设备100运输时的装箱量，而且将弹性件17对连接件14的支撑作用发挥到最大，起到开门省力的效果。
与现有技术相比，本发明提供的铰链1及具有其的制冷设备100，其有益效果在于：通过设置止动件13来限制动铰链座12相对定铰链座11转动的角度，从而限制门体3的开门角度并使门体3在打开所述开门角度后悬停；通过限位块16可拆卸组装于限位槽124中，在铰链1的运输过程中，或者将铰链1装配于制冷设备100时，可以将限位块16装配于限位槽124中，从而防止定铰链座11相对动铰链座12来回翻转而对铰链1造成损坏，现场工人在安装时不需要用手扶住动铰链座12便可使动铰链座12固定贴合于门体3以便于安装，大大提高了安装效率，降低了人工成本；动铰链座12绕摆动轴123相对定铰链座11转动时，摆动轴123随之摆动并牵引连接件14带动活动轴151一并运动，而且运动过程中在各个部件的相互限制下，摆动轴123、活动轴151与枢转轴113三者始终处于平行状态，而动铰链座12、枢转轴113、摆动轴123、连接件14、活动轴151、弹性件17和定铰链座11共同构成了曲柄滑块机构，将动铰链座12的枢转运动转化为弹性件17的直线运动，相较于弹性件17做弧线运动，大大减少了弹性件17运动所需要的活动空间，尤其是在内外方向上，因此可将铰链1的厚度做薄；通过轴套18套设于摆动轴123和活动轴151二者至少其一的外周、以及设于套筒181内壁的储油筋182，可以在储油筋182之间加润滑油，润滑油可以自轴套18中慢慢渗出至摆动轴123、活动轴151，从而起到对摆动轴123、活动轴151的润滑保护作用，使铰链1转动顺畅，减少使用过程中的磨损和噪音，延长铰链1和制冷设备100的使用寿命。
