Description

可控制锁门噪音的自动门锁噪音抑制机构
本申请为2014年07月04日向中华人民共和国国家知识产权局递交的申请号为201410316995.2的发明申请、以及申请号为201420368443.1的实用新型申请的在后申请。
技术领域
本发明实施例涉及自动门锁，特别是涉及一种可人为控制锁门时锁舌以缓慢速度伸出，因而可避免噪音扰民的可控锁门噪音的自动门锁噪音抑制机构。
背景技术
现有技术中的自动门锁主要包括主锁体、副锁体、锁舌及机械传动机构等部件。传统的自动门锁在其门扇与门框闭合锁门时，无需使用钥匙，在具有弹力的滚轮或斜舌碰撞门框等机械传动机构的作用下瞬间即可将锁舌弹出，在锁舌弹出过程中，由于速度较快且无法人为控制，因此门锁的机械传动部件之间及锁舌与门扣板之间都会因摩擦和碰撞而产生明显噪音，且这种噪音在夜间更加更易于扩散，并因此影响到邻居和周围住户。为此，有人在锁中设置了减震装置，如在锁舌与扣板接触的一端包覆有柔性的非金属材料，以便在锁舌接触柔性的非金属材料的时候降低噪音。然而，锁舌在机械传动机构的作用下，在快速穿出主锁体后还未接触柔性的非金属材料时已经产生了机械传动噪音，且由于非金属柔性材料容易变质失去原有特性或在锁舌频繁碰撞下，容易移位或脱落而降低使用寿命。
发明内容
本发明旨在解决上述问题，而提供一种在锁门时可人为控制锁舌以慢速伸出，因而可减少或消除噪音，且使用安全可靠的可控制锁门噪音的自动门锁噪音抑制机构。
为实现目的，本发明提供一种可控制锁门噪音的自动门锁噪音抑制机 构，该机构包括锁壳、锁芯及锁舌组件，其特征在于，在所述锁壳内设有与所述锁舌组件活动连接的控制锁门噪音的手控组件，使得在锁门时，所述锁舌组件可在手控组件控制下缓慢伸出锁壳外而上锁，在所述锁壳上设有自动锁门用的离合组件，该离合组件与所述锁舌组件活动连接，使得装设门锁的门体与门框接触时触发离合组件并释放锁舌组件而自动锁门。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1
参阅图1，本发明的可控制锁门噪音的自动门锁噪音抑制机构包括锁壳10、锁芯20、锁舌组件30、手控组件40、离合组件50及止逆装置60。
如图1、图2所示，所述锁壳10包括不锈钢制成的锁壳主体11及上盖12，在上盖12上设有锁芯孔111，在锁壳主体11的正面，即锁壳的靠门体外侧的一面分别设有锁芯孔111和手控组件连接孔112，分别用于装设锁芯20和手控组件40的转轴401。在锁壳主体的前侧面设有一个供锁 舌伸出或缩回的锁舌孔113，与所述侧面相垂直的锁壳主体的另一个侧面设有离合槽114，用于离合组件的第二翘板52的限位。在锁壳主体内侧表面设有块状止逆凸起115，其用于和止逆装置的止逆勾64和防滑勾65相配合。
如图1、图2，在锁壳10内装有锁芯20，其可以是公知的弹子锁芯，其外端部置于锁壳的锁芯孔111处。在锁芯20外近外端部固定有主动齿轮321，其可随锁芯20同步转动，并与第一齿条322相啮合。
图1、图2中，在锁壳内设有锁舌组件30，本实施例中，该锁舌组件30包括一个锁舌31、锁舌驱动机构32及锁舌推板33。所述锁舌31可以是公知的锁舌，在锁舌31的末端固接有锁舌推板33，该锁舌推板33呈条状，其上间隔地设有纵向的第一条形滑孔331和第二条形滑孔332，用于锁舌驱动机构32的第一齿条上的第一推杆3221和第二推杆3222在其中滑动，推动锁舌推板33带动锁舌31往复移动。在本发明的其它实施例中，锁舌31也可以是两个，两个锁舌间隔设置，并可通过一连杆相连接，使得两个锁舌可同步移动。所述锁舌推板33与所述锁舌驱动机构32活动连接，锁舌驱动机构32则与所述锁芯20活动连接，使得通过转动钥匙可带动锁舌驱动机构32前后移动，实现锁舌31的伸出或缩回。如图1、图2，所述锁舌驱动机构32包括主动齿轮321及第一齿条322，所述主动齿轮321固定于锁芯20上，在锁芯20随钥匙转动时，主动齿轮321可随锁芯20同步转动。所述第一齿条322活动设置于锁壳10内侧表面，并与所述主动齿轮321相啮合。在第一齿条322上间隔地设有第一推杆3221及第二推杆3222，该第一推杆3221及第二推杆3222分别活动地穿置于锁舌推板33上的第一条形滑孔331和第二条形滑孔332内，并可在第一条形滑孔331和第二条形滑孔332内移动，使得当主动齿轮321随锁芯20转动时，由主动齿轮321带动第一齿条322作直线移动，并通过其第一推杆3221和第二推杆3222推动锁舌推板33前后移动，从而实现锁舌31的伸出或缩回。
为了抑制自动门锁在锁门时的噪音，本发明设置了手控组件40，如图1、图2所示，本实施例中，所述手控组件40包括转轴401、第二齿条402、单向离合齿轮403、单向离合器404及手控部件405。所述转轴401为传 动部件，其设置方向与锁舌31的方向相垂直，并经锁壳10上的手控组件连接孔112贯穿锁壳内外。该转轴401的一端活动地穿过锁壳10并延伸至门体外部，其端部固接有手控部件405。在该转轴401上装设有单向离合齿轮403和单向离合器404，该单向离合齿轮403和单向离合器404可以是公知的单向离合齿轮和单向离合器，它们可以是滚子式单向离合器和单向离合齿轮，也可以是楔块式单向离合器和单向离合齿轮。本实施例中，单向离合齿轮403和单向离合器404为棘齿式单向离合器和单向离合齿轮。如图2，该单向离合齿轮403和单向离合器404包括外座圈和与之转动连接的内座圈，单向离合齿轮403和单向离合器404同轴地装设于所述转轴401上，其中，所述单向离合器404的内座圈与所述转轴401固接，单向离合器的外座圈与锁壳10固接。所述单向离合齿轮403的内座圈固接于转轴401上，其外座圈则与第二齿条402相啮合。所述转轴401活动地穿过锁壳10并延伸至门体外部，其端部固接有手控部件405，该手控部件405可以是公知的L形门把手，通过该手控部件405可控制锁门时锁舌31伸出的速度，并通过控制锁舌31伸出的速度抑制自动门锁锁门噪音。
如图1、图2，当打开门锁时，通过钥匙带动锁舌驱动机构32推动锁舌31及第二齿条402向锁壳10内移动，第二齿条402推动单向离合齿轮403同向转动，此时，单向离合齿轮403的外座圈与内座圈分离，而单向离合齿轮403和单向离合器404的内座圈则与转轴401固定不动。当第二齿条402移动到位且锁舌31完全缩回到锁壳内时，门锁处于开启状态。
当锁门时，由锁舌驱动机构32推动锁舌31及第二齿条402或由于离合组件50释放而带动锁舌31向锁壳10外移动，单向离合齿轮403的外座圈由第二齿条402推动向锁壳10外方向同向转动，此时，单向离合齿轮403的外座圈与内座圈相互啮合，并带动转轴401同步转动，单向离合器404的内座圈也与转轴401同步转动。当第二齿条402移动到位且锁舌31完全伸出到锁壳10外时，门锁处于锁定状态。此时，转轴401不能反向转动，即通过转动手控部件405不能打开门锁。为了抑制锁门噪音，在第二齿条402及锁舌31向锁壳10外移动过程中，可向单向离合齿轮403旋转方向慢速地同向旋转手控部件405，以便通过人为控制转轴的转速而控制第二齿条402及锁舌31向外移动的速度，使得在锁门过程中门锁周 围环境中听不到碰撞和摩擦声，因而有效抑制了自动门锁的锁门噪音。
为了加强自动门锁的使用安全性，本发明的机构还设置了止逆装置60。如图1、图2所示，该止逆装置60包括弹簧连接柱61、复位弹簧62、止逆勾连接柱63、止逆勾64、防滑勾65、防滑勾连接柱66、防滑勾扭簧67、定位销68及连动片69。所述止逆勾64为片状体，其端部呈勾状，其勾体角度最好应在90～92度之间，使得止逆勾64易于与止逆凸起115相勾合和相脱离。该止逆勾64可转动地装在止逆勾连接柱63上，并与所述锁壳10的止逆凸起115相离合。在止逆勾64上设有防滑勾连接柱66，防滑勾65为片状体，其端部呈勾状，该防滑勾65活动套设于防滑勾连接柱66上，防滑勾体角度最好应在90～92度之间，使得止逆勾64易于与止逆凸起115相勾合和相脱离。所述连动片69用定位销68活动连接于防滑勾65上，连动片69的另一端可转动连接于锁舌驱动机构32的第二推杆3222上。在防滑勾65上装有复位用的防滑勾扭簧67。当锁舌31向锁壳10外移动到位时，所述止逆勾64和防滑勾65同时勾住所述止逆凸起115，使得当有人从门外转动手控组件40时，止逆勾64和防滑勾65可阻止所述转轴401反向转动。当锁舌31向锁壳10内移动时，第一齿条322上的第二推杆3222先通过连动片69将防滑勾65脱开，并继续向锁壳10内方向移动，再进一步推开止逆勾64，解除止逆而后继续向锁壳10内移动的方向移动，最终推动锁舌推板33及锁舌31直到锁舌31完全缩回到锁壳10内。
图1、图2中，所述锁壳10上设有自动锁门用的离合组件50，该离合组件50包括第一翘板51、第二翘板52、翘板支架53、弹簧套54、弹簧套支架55及偏压力弹簧56。所述第一翘板51为条形板状体，在其靠锁舌31的一端端部设有L形折弯511，该端为触发端511，该触发端511延伸至锁壳10的靠锁舌31一侧外部。第一翘板51的另一端为自由端512。第一翘板51在所述L形折弯处用销钉57可转动连接于锁壳10外侧。所述第二翘板52可转动连接在固定于锁壳10内侧的翘板支架53上，在第二翘板52上装有扭簧58。所述弹簧套54一端固定在所述锁舌31上，另一端活动穿设于弹簧套支架55上，在弹簧套54内装有偏压力弹簧56，该偏压力弹簧56的一端连接到锁舌31上，另一端连接到锁壳10侧壁上， 当离合组件50释放时，偏压力弹簧56通过弹力将锁舌31弹出。在所述弹簧套54上靠近弹簧套54与锁舌31连接部设有供所述第二翘板52卡入的缺口541。当锁舌31向锁壳10内移动并完全缩回到锁壳10内时，第二翘板52在扭簧58作用下卡入所述缺口541，而将锁舌31锁定。该离合组件50与所述锁舌组件30活动连接，使得装设门锁的门体与门框接触时触发离合组件50并释放锁舌组件30而自动锁门。如图1，自动锁门时，第一翘板的触发端511端部碰触到门框时，第一翘板的自由端512在受到所述触发端511作用时绕所述销钉57摆动而翘起，翘起的自由端将第一翘板51抬起而释放锁舌组件30，实现了自动锁门。
