Description

铰链及具有其的制冷设备 技术领域
本发明涉及一种铰链，尤其涉及一种铰链及具有该铰链的制冷设备。
背景技术
制冷设备如冰箱、冷柜、酒柜等通常采用铰链连接门体和柜体以实现门体的打开或关闭，但是门体打开到一定角度后需要使门体悬停，以便用户存取物品。现有制冷设备的铰链通常在柜体铰链座的侧壁上设置弧形槽，门体翻转打开的过程中，门体铰链座的摆动轴在弧形槽内往复转动而实现门体的打开或关闭，通过弧形槽的端部实现门体在打开后悬停。
但是弧形槽本身需要占据一定的侧壁厚度，进一步地在侧壁的厚度方向上弧形槽的两端与侧壁的边界之间还需要留设一定的厚度余量，以保证侧壁的强度，而且由于制冷设备的门体一般重力较大，故需要保证留设的厚度余量足够大以承担门体重力，导致铰链的厚度无法做薄；此外，铰链中用于支撑门体的弹性支撑件在上下运动的过程中，会随着弧形槽内的轴前后摆动，也需要占据铰链在厚度方向的空间，进一步限制了铰链的厚度无法做薄；再者，铰链一般都凸出设置于制冷设备的外侧，使得制冷设备整体的厚度较大，储运时装箱量减少，使用时的空间占用较大。

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
本发明一实施例提供一种铰链及具有该铰链的制冷设备，通过将铰链的结构重新设计使其在保持正常工作的状态下铰链的尺寸做得更薄，从而缩小制冷装置的尺寸。
如图1或图2所示，本申请一实施例提供的制冷设备包括铰链1、柜体2和门体3，柜体2内部围出制冷空间，门体3组装于柜体2并可相对柜体2转动以打开或关闭所述制冷空间，所述制冷设备具体可设为冰箱、冷柜、酒柜等。门体3与柜体2之间通过铰链1连接，铰链1支撑门体3的打开和关闭，铰链1厚度做薄可使制冷设备运输的过程中装箱量增大。
如图3至图7所示，本实施例的铰链1，包括柜体铰链座11及与其转动连接的门体铰链座12，门体铰链座12与门体3固定连接，柜体铰链座11与柜体2固定连接。本实施例的门体3从柜体2的侧面翻开，对应的，铰链1设置在柜体2和门体3的侧面。为清楚地说明连接位置关系，本实施例中，以铰链1朝向柜体2的方向定义为前，反方向定义为后，门体3相对于柜体2的方向定义为上，反方向定义为下，从前方正对铰链1的两侧分别定义为左和右。
本实施例中的铰链1还包括滑动连接于柜体铰链座11的滑动部、以及同时枢转连接于门体铰链座12和滑动部的连接件13、限制滑动部沿直线运动的限位部，所述限位部可以设置在柜体铰链座11上，也可以设置在铰链1的封装盖板上，也可以同时设置于多个地方，作用是限制所述滑动部的运动方式，使其在连接件13的牵引下只能做直线运动，柜体铰链座11、门体铰链座12、连接件13、所述滑动部和所述限位部共同构成了曲柄滑块机构，将门体铰链座12的转动运动转化为所述滑动部的直线运动。在门体3绕着铰链1翻转打开的过程中，带动固定在门体3上的门体铰链座12绕着柜体铰链座11转动，门体铰链座12牵引着连接件13带动所述滑动部一 并运动，所述滑动部在所述限位部的限制下做直线运动。
铰链1还包括多个弹性支撑件16，多个弹性支撑件16间隔并排设置，每个弹性支撑件16的一端与所述滑动部连接，另一端抵持柜体铰链座11。通过所述滑动部带动弹性支撑件16沿直线运动，使本实施例的铰链1区别于传统铰链中弹性支撑件的摆动运动，一方面，所述滑动部使弹性支撑件16在铰链1内部所需的活动空间大大减少，避免了弹性支撑件16做前后摆动而占用大量空间的问题，而且取消了传统铰链中设于柜体铰链座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，从而可以将铰链1做得很薄且不影响铰链1结构的强度，增加了储运时的装箱量，减少了使用时的占用空间；另一方面，多个弹性支撑件共同分担对门体铰链座12以及门体3的支撑作用，可降低对每个弹性支撑件的强度的要求，从而可使每个弹性支撑件的外径做小，进一步减薄铰链1的厚度；此外，通过所述限位部于所述滑动部中运动，可以利用所述滑动部来限制门体3相对柜体2打开的角度，当所述限位部运动至所述滑动部靠近门体铰链座11的一端时，门体3打开至最大开门角度并且在所述滑动部的限制下悬停。
柜体铰链座11还包括支撑座114，多个弹性支撑件16均抵持于支撑座114及所述滑动部，多个弹性支撑件16结构相同，间隔均匀设置后对支撑座114和所述滑动部施加的力大小相同、方向相同，所述滑动部被多个弹性支撑件16以大小和方向均相同的力抵持，弹性支撑件16在支撑座114的支撑下，与所述滑动部连接的一端随着所述滑动部的运动而同步运动，由于所述滑动部做直线运动，所以多个弹性支撑件16也做直线运动，使铰链1内部需要的活动空间减少，铰链1的厚度可以做薄。
如图4或图5所示，具体地，在本实施例中，弹性支撑件16设置有两个，两个弹性支撑件16设置于连接件13的两侧，优选地，两个弹性支撑件16对称设置于连接件13的两侧，从而可使两个弹性支撑件16均匀地分担对门体铰链座12以及门体3的支撑作用，使连接件13均匀受力。在其它实施例中，弹性支撑件16的数量也可以根据实际需要设置多个。
参看图4至图5，柜体铰链座11包括柜体连接板113和转轴111，门体铰链座12转动连接于转轴111，转轴111平行于柜体连接板113。
优选地，所述滑动部在所述限位部的限制下运动方向平行于柜体连接板113并垂直于转轴111，进一步牵引弹性支撑件16随所述滑动部做平行于柜体连接板113的运动，将弹性支撑件16的运动限制在平行于柜体连接板113的平面上，所述滑动部沿上下方向直线运动，弹性支撑件16也沿着上下方向压缩或伸展，避免了所述滑 动部和弹性支撑件16在垂直于柜体连接板113的方向上的运动，减小了铰链1空间尺寸的占用，使铰链1可以做得更薄。
其中，所述滑动部包括滑动轴14，所述限位部包括滑动槽15，滑动轴14配接于滑动槽15中并沿滑动槽15运动，滑动槽151沿垂直于转轴111的轴线方向直线延伸，滑动槽15包括相互平行的一对限位面，滑动轴14设置于所述一对限位面之间，滑动轴14沿着滑动槽15滑动，滑动槽15可以是通孔或盲孔，滑动槽15纵切面可以是腰型，所述一对限位面之间的宽度等于或略大于滑动轴14的直径，滑动轴14在所述一对限位面之间滑动。
此外，滑动轴14也可以设置为块状，滑动槽15设置为与块状相匹配的形状，限制块状的所述滑动部运动。
柜体铰链座11还包括相对设置的一对侧壁112，一对侧壁112分别设置有滑动槽15，也即滑动槽15也设置有一对，且一对滑动槽15与一对侧壁112一一对应，侧壁112分别设置于柜体连接板113的相对两端，一对侧壁112相对平行的设置，对应的，每个侧壁112上的滑动槽15也对应的相互平行，滑动轴14的轴向两端分别配接于一对滑动槽15中，从而使滑动轴14在相互平行的侧壁112的滑动槽15上运动，保障了运动过程中滑动轴14始终平行于柜体连接板113和转轴111。
进一步地，弹性支撑件16包括支撑杆161，支撑杆161与滑动轴14连接的一端设有开口的凹槽1611，滑动轴14抵持于凹槽1611内，所述开口朝向滑动轴14，在滑动轴14运动过程中，若产生突变如多个弹性支撑件16之间的力产生不同的变化，或大小或方向的不等的情况时，受力更大一侧的滑动部可从支撑杆161端部的所述开口中产生远离支撑杆161的趋势，这样避免了多个弹性支撑件16存在干涉，使自由度小于1的情况，而且便于装配。
弹性支撑件16还包括套设于支撑杆161外侧的弹性件162，支撑杆161靠近连接件13的一端还设置有限位凸起，弹性件162抵持于柜体铰链座111和所述限位凸起之间。
在本实施例中，弹性件162设置为弹簧，所述弹簧始终处于压缩状态，由于所述滑动部的运动的位移量相对于铰链1的尺寸并不大，通过调整所述弹簧的弹性系数及尺寸，使所述弹簧在滑动部沿所述限位部滑动的过程中始终处于压缩状态，当多个支撑杆161中的任一个产生远离所述滑动部的趋势时，所述弹簧恢复形变，弹力驱使支撑杆161继续与所述滑动部相抵，支撑杆161不会与所述滑动部完全脱离，从而保障该铰链1运动过程中不会发生失效损坏的情况。另外在门体3打开的过程 中，压缩的所述弹簧逐渐恢复形变，对门体3的打开提供了支持力，形成了辅助门体3打开的作用，可以使开门省力。
参看图4至图5，本实施例的支撑座114横设于一对侧壁112之间，在支撑座114上设置有与弹性支撑件16数量对应的多个开孔，每个支撑杆161各自穿过与其对应的所述开孔并可相对支撑座114上下运动，但始终不脱出所述开孔，在所述弹簧的弹性作用下，支撑杆161可以随着所述弹簧的伸张和收缩而运动，由于支撑杆161一端随所述滑动部直线运动，另一端插置在所述开孔内，使得支撑杆161只能沿直线运动，结合上文的描述，本实施例优选的方案使得滑动轴14的运动方式限定在平行于柜体连接板113的平面上做上下直线运动。
进一步地，门体铰链座12绕转轴111转动，门体铰链座12包括门体连接板122、相对设置的一对侧板123、以及与转轴111平行的摆动轴121，门体连接板122与门体3连接，一对侧板123连接于门体连接板122的左右两端且位于门体连接板122的同一侧，一对侧板123位于一对侧壁112之间且与一对侧壁112一一对应，连接件13同时枢转连接于滑动轴14和摆动轴121，滑动轴14也平行于摆动轴121，即三个轴相互平行，当门体铰链座12绕转轴111翻转运动时，带动滑动轴14运动时在各部件的限制下始终平行于转轴111。
摆动轴121连接一对侧板123，摆动轴121位于一对侧壁112之间，也即摆动轴121与柜体铰链座11无连接，取消了现有技术中设于柜体铰链座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，增加了储运时制冷设备的装箱量，减少了使用时的占用空间。
连接件13的上下两端分别设置有通孔，摆动轴121和滑动轴14分别穿过所述通孔，从而使连接件13与摆动轴121和滑动轴14之间始终枢转连接，当摆动轴121、连接件13和滑动轴14运动时，三者之间可发生相对的转动。
进一步地，门体铰链座12具有打开门体3的开门位置以及关闭门体3的关门位置，门体铰链座12于所述开门位置时，摆动轴121的轴线位于柜体连接板113所在的平面上，或者摆动轴121位于柜体连接板113朝向柜体2的一侧。
如图2和图3所示，门体3和柜体2之间形成空腔100，门体3包括关闭状态和打开状态，在门体3由关闭状态切换至打开状态时，摆动轴121移至空腔100，摆动轴121与门体3和柜体2之间始终存在间距，门体3和柜体2之间，一般均需要设置门封4，在门体3和柜体2和门封4之间存在空腔100，摆动轴121摆动时，由铰链1内部运动至空腔100的位置，通过根据空腔100的位置调节铰链1的高度，可 以使摆动轴121不与冷柜的其他结构之间发生干涉，这样摆动轴121的摆动由于已经在滑动槽15对滑动轴14的限位，摆动轴121不会摆动过度，不需要设置传统铰链中的弧形槽，且摆动轴121的摆动不占用铰链1内部的空间，而是利用了冷柜本身具备的空腔100，使得铰链1的厚度可以进一步地做得更薄。
参看图7，进一步地，门体铰链座12由所述关门位置运动至所述开门位置的过程中，连接件14与柜体连接板113互不干涉，门体铰链座12包括贴靠门体3的底板，具体地，可以通过设置所述底板和门体连接板113之间的距离实现，从而可以使摆动轴121顺利由铰链1内部摆动至空腔100的位置，使得铰链1的厚度可以进一步地做得更薄。
参看图3，连接件13位于摆动轴121和滑动轴14之间的部分向远离柜体2的方向凹陷，以进一步避免门体铰链座12由所述关门位置运动至所述开门位置的过程中，连接件13与柜体连接板113发生干涉。
进一步地，参看图3以及图5至图7，转轴111与滑动轴14的轴线所形成的平面与柜体连接板113平行。
铰链1包括收紧状态和释放状态，铰链1于收紧状态时，弹簧处于弹力最大的状态，对应制冷设备的门体3关闭；铰链1于释放状态时，弹簧恢复了一些形变，处于弹力最小的状态，对应的制冷设备的门体3打开。在铰链1由收紧状态切换至释放状态的过程中，转轴111和滑动轴14始终位于同一平面，摆动轴121摆动至远离所述平面，滑动轴14沿滑动槽15朝向转轴111方向滑动。
进一步地，参看图3和图6，铰链1于收紧状态下，门体铰链座12于所述关门位置时，摆动轴121的轴线位于转轴111和滑动轴14的轴线所形成的平面上，这样设置铰链1的厚度可以做到最薄，进一步增大制冷设备运输时的装箱量。
进一步地，在本实施例中，铰链1还包括套设于滑动轴14外侧的轴套17，轴套17设置于支撑杆161和滑动槽15之间，支撑杆161设置在轴套17和连接件13之间，轴套17限制支撑杆161的左右移动，如图4所示，连接件13可以伸出两个支脚，分别设置在支撑杆161的两侧，滑动轴14的左右两侧各设置一个轴套17，该铰链1为左右对称结构。
进一步地，铰链1还包括盖板，所述盖板封装铰链1，形成铰链1的外表面，可以提高所述制冷设备的美观性。
在其它实施例中，所述限位部也可以设置于盖板，并使所述滑动部与所述限位部配合并沿所述限位部做直线运动，从而限制弹性支撑件16的运动方向只能平行于 柜体连接板113且运动方向固定的作用。
参看图8，在变化的实施方式中，柜体铰链座11还具有相对设置的一对弧形槽115，一对弧形槽115分别设置于一对侧壁112，摆动轴121配接于一对弧形槽115中并沿弧形槽115前后摆动，通过弧形槽115可以限制门体铰链座12相对柜体铰链座11转动的角度，从而限制门体3相对柜体2打开的角度并使门体3悬停。
同样地，弹性支撑件16可以设置多个。
弧形槽115具有靠近滑动槽14的近端以及远离滑动槽14的远端，滑动槽14具有靠近弧形槽115的极限近端以及远离弧形槽的极限远端；摆动轴121摆动至所述近端时，门体3处于关闭状态，摆动轴121摆动至所述远端时，门体3处于打开状态并悬停。
进一步地，摆动轴121摆动至所述远端时，滑动轴14与所述极限近端之间具有间隙，弹性支撑件16具有压缩形变量。这样，施加外力使门体铰链座12随门体3转动至开门位置时，由于滑动轴14与所述极限近端之间的间隙的存在，弹性支撑件16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121形成连接件14驱使摆动轴121向所述远端运动的力，从而使门体铰链座12具有绕转轴111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。
与现有技术相比，本实施例具有以下有益效果：通过所述滑动部带动弹性支撑件16沿直线运动，使本实施例的铰链1区别于传统铰链中弹性支撑件的摆动运动，一方面，所述滑动部使弹性支撑件16在铰链1内部所需的活动空间大大减少，避免了弹性支撑件16做前后摆动而占用大量空间的问题，而且取消了传统铰链中设于柜体铰链座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，从而可以将铰链1做得很薄且不影响铰链1结构的强度，增加了储运时的装箱量，减少了使用时的占用空间；另一方面，多个弹性支撑件共同分担对门体铰链座12以及门体3的支撑作用，可降低对每个弹性支撑件的强度的要求，从而可使每个弹性支撑件的外径做小，进一步减薄铰链1的厚度；此外，通过所述限位部于所述滑动部中运动，可以利用所述滑动部来限制门体3相对柜体2打开的角度，当所述限位部运动至所述滑动部靠近门体铰链座11的一端时，门体3打开至最大开门角度并且在所述滑动部的限制下悬停。
上文所列出的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或 变更均应包含在本发明的保护范围之内。
