在介绍本申请的技术方案之前，再详细介绍下相关技术中的技术问题。
门锁是门上的重要结构件之一，门锁可以控制门进而打开与关闭房间、空间等等。现有技术通常采用纯机械式的门锁结构，即利用钥匙带动门锁内的结构运动从而实现开关门。随着科技的进步以及用户的需求不断发生改变，现在电子锁已经出现了在了人们的视野中，并备受用户注意。电子锁在常规情况下不需要使用钥匙，只需要通过人脸识别，密码输入，指纹输入，声音识别等方法便可通过内置电路自动带动门锁内的结构运动从而实现开关门。这带来了极大的便利与用户体验感。但是，一旦电机锁内的电机、电路结构、或者其他结构件发生了故障，导致电机锁内的某个环节出现了问题，就会导致电机锁无法正常工作，门外的用户便无法通过电子锁开门的方法打开门进入房间，只能通过钥匙开门的方法进入房间。并且门内的用户也无法打开门走出房间，此时只能对门或门锁采用暴力拆除的方法，从而对门造成不可逆的损失，极大地增加了开锁的难度与风险性。
请一并参考图1-图3，图1为本申请一实施方式中驱动机构的结构示意图。图2为本申请一实施方式中驱动机构的原理示意图。图3为图1中沿A-A方向的截面示意图。本实施方式提供了一种用于门锁的驱动机构1，所述驱动机构1包括电机10。行星齿轮组件20，所述行星齿轮组件20包括齿圈21、行星轮22、以及太阳轮23，所述电机10旋转连接所述太阳轮23，所述齿圈21具有收容空间211，所述行星轮22与部分所述太阳轮23均设于所述收容空间211内，且所述行星轮22旋转连接于所述太阳轮23与所述齿圈21之间。保持架30，所述保持架30设于所述行星齿轮组件20一侧，所述齿圈21与所述太阳轮23均抵接所述保持架30，所述行星轮22连接所述保持架30；当所述齿圈21处于固定状态时，所述太阳轮23在所述电机10的带动下进行旋转，以使所述行星轮22相对所述齿圈21旋转；或者，当所述太阳轮23处于固定状态时，可通过控制所述齿圈21进行旋转，以使所述行星轮22相对所述太阳轮23旋转。
本实施方式提供的驱动机构1是门锁的重要结构件之一。门锁主要包括驱动机构1、锁芯、锁体。其中，锁体装设于门内，锁芯装设于锁体中，锁芯的拔轮可驱动锁体的锁舌伸出或收回从而实现开关门。驱动机构1设于门外，且同时连接门与门内的锁芯，驱动结构的运动可带动锁芯进行运动，从而实现锁舌伸出与收回。
本实施方式提供的驱动机构1包括电机10与电源。其中，电机10电连接电源，电源可为电机10提供所需的能量，电机10在接收电能后便可进行工作与旋转。可选地，电源可以包括不可充电电池或可充电电池。
本实施方式提供的驱动机构1还包括行星齿轮组件20。其中，行星齿轮组件20由多个结构件组成。例如行星齿轮组件20包括齿圈21、行星轮22、以及太阳轮23。三个结构件的名称均为本领域技术人员行业内对齿轮的专业的技术术语。齿圈21为一圆环形齿轮，齿圈21内设有收容空间211，且齿圈21具有一圈内齿与一圈外齿。另外，行星轮22与太阳轮23均具有一圈外齿，且行星轮22与部分太阳轮23均设于收容空间211内。也可以理 解为部分太阳轮23设于收容空间211内，而其余的太阳轮23则设于收容空间211外。至于电机10旋转连接太阳轮23。可以理解的是，电机10旋转连接设收容空间211外的太阳轮23，并带动收容空间211内的太阳轮23旋转。其次，电机10旋转连接太阳轮23可以为电机10直接连接太阳轮23。或者，电机10与太阳轮23之间还设有其他传动机构40，传动机构40的一端旋转连接电机10，传动机构40的另一端旋转连接太阳轮23。电机10旋转带动传动机构40旋转，传动机构40旋转进而带动太阳轮23旋转。此时可以看成电机10间接旋转连接太阳轮23。至于传动机构40的具体结构，本申请将在后文进行介绍。
其次，行星轮22旋转连接于太阳轮23与齿圈21之间。也可以理解为行星轮22的一端旋转连接齿圈21的内齿，行星轮22相对的另一端旋转连接太阳轮23的外齿。齿圈21、行星轮22、以及太阳轮23三种齿轮通过行星轮22将整个行星轮22组件联动在了一起。可选地，行星轮22的数量可以为多个，且每个行星轮22均匀间隔设置。例如行星轮22的数量为3个，且每个行星轮22相隔120°设置。这样可提高行星轮22组件与保持架30转动的稳定性。
本实施方式提供的驱动机构1还包括保持架30，其中，保持架30为安装行星齿轮组件20、以及其他结构件的支架。行星齿轮组件20设于安装件的一侧，锁芯设于安装件的另一侧。行星齿轮组件20中的齿圈21与所述太阳轮23均抵接所述保持架30，所述行星轮22连接所述保持架30。这样齿圈21与太阳轮23在旋转时，便不会影响到保持架30的运动状态。而行星轮22连接保持架30，因此行星轮22的旋转可带动保持架30共同进行旋转。保持架30的旋转可进一步带动锁芯进行运动。
上述内容即为本实施方式中提供的驱动机构1的机械结构。至于具体如何实现驱动机构1的运动。本实施方式可通过齿圈21、行星轮22、以及太阳轮23的相互配合最终使行星轮22进行旋转，进而带动保持架30旋转，最终带动连接保持架30的锁芯运动从而实现开关门。齿圈21、行星轮22、以及太阳轮23三者具体的配合方法可以理解为，通过使齿圈21或太阳轮23中的一个结构固定，使齿圈21或太阳轮23中的另一个与行星轮22进行旋转，从而使行星轮22可绕太阳轮23进行公转，进而带动保持架30旋转。例如，当所述齿圈21处于固定状态时，所述太阳轮23在所述电机10的带动下进行旋转，以使所述行星轮22相对所述齿圈21旋转，进而带动保持架30旋转，便可通过电机10来实现开关门。当电机10出现故障无法正常工作时，太阳轮23便无法进行转动，此时太阳轮23处于固定状态，因此便可通过直接控制所述齿圈21进行旋转，以使所述行星轮22相对所述太阳轮23旋转，进而带动保持架30旋转。这样即使当电机10发生故障时，依然可以通过控制齿圈21进行旋转来实现开关门。可选地，使齿圈21固定与旋转的结构与方法本申请将在后文进行详细介绍。
综上，本申请提供的驱动机构1，通过采用电机10控制太阳轮23旋转，或者通过直接控制齿圈21旋转两种方式来实现开关门，增加了控制门锁的方法，避免了单一的电机10锁中因电机10损坏而无法开关门的问题，降低了开门的难度与风险性。
可选地，请再次参考图1，传动机构40包括第一齿轮41、第二齿轮42、以及第三齿轮43，第一齿轮41旋转连接电机10，第二齿轮42旋转连接第一齿轮41，第三齿轮43旋转连接第二齿轮42。通过多个齿轮可将电机10的转动传输至太阳轮23上。
请一并参考图4，图4为本申请另一实施方式中驱动机构的结构示意图。本实施方式中，所述驱动机构1还包括保护壳44，所述保护壳44罩设齿轮齿轮组件，本实施方式可通过保护壳44将传动机构40更好地保护起来。
请再次参考图3与图5，图5为本申请一实施方式中驱动机构的部分分解示意图。本实施方式中，所述太阳轮23包括同轴设置的第一子太阳轮231与第二子太阳轮232，所述 电机10旋转连接所述第一子太阳轮231；所述第二子太阳轮232设于所述收容空间211内，且所述第二子太阳轮232旋转连接所述行星轮22。
上述内容介绍了部分太阳轮23设于收容空间211内，具体地，在本实施方式中，太阳轮23可包括同轴设置的第一子太阳轮231与第二子太阳轮232。其中第一子太阳轮231设于收容空间211外，并旋转连接电极。第二子太阳轮232设于所述收容空间211内，且所述第二子太阳轮232旋转连接所述行星轮22。这样便可实现太阳轮23即旋转连接收容空间211外的电机10，又旋转连接收容空间211内的行星轮22。
请一并参考图6，图6为本申请又一实施方式中驱动机构的结构示意图。本实施方式中，所述驱动机构1还包括齿轮支架50，所述齿轮支架50旋转连接于所述齿圈21的一侧，所述齿轮支架50具有固定状态或旋转状态。
上述内容介绍了齿圈21具有固定状态和旋转状态，本实施方式将介绍如何使太阳轮23进行固定和旋转。具体地，本实施方式可通过增设齿轮支架50，使齿轮支架50旋转连接于所述齿圈21的一侧，这样变将齿轮支架50与齿圈21进行了联动。另外，齿轮支架50具有固定状态或旋转状态。因此，本实施方式可通过齿轮支架50来控制齿圈21的运动。当齿轮支架50为固定状态时，齿圈21也为固定状态。当齿轮支架50为旋转状态时，齿圈21也为旋转状态。
请一并参考图7-图10，图7为本申请又一实施方式中驱动机构去除壳体后的结构示意图。图8为本申请另一实施方式中驱动机构沿A-A方向的截面示意图。图9为本申请一实施方式中齿轮支架具有旋转状态时的示意图。图10为本申请一实施方式中驱动机构的俯视图。本实施方式中，所述驱动机构1还包括手柄支架51、及壳体60，所述手柄支架51滑动连接所述齿轮支架50，且所述手柄支架51的滑动方向垂直于所述齿圈21的旋转方向。所述壳体60内具有容置空间61，所述电机10、以及所述行星齿轮组件20均设于所述容置空间61内，所述壳体60上开设有连通所述容置空间61的通孔62，部分所述手柄支架51贯穿所述通孔62，且所述通孔62的至少部分侧壁上开设有限位槽63，所述限位槽63与所述手柄支架51相互配合以限制所述手柄支架51的旋转。
本实施方式将详细介绍如何使齿轮支架50具有固定状态或旋转状态。具体地，可增设手柄支架51及壳体60，并使手柄支架51滑动连接所述齿轮支架50，且所述手柄支架51的滑动方向(如图7中D1所示的方向)垂直于所述齿圈21的旋转方向(如图7中D2所示的方向)。也可以理解为手柄支架51不仅连接齿轮支架50，还可相对齿轮支架50进行滑动。
另外，壳体60为驱动机构1的外壳，部分结构件可设于壳体60内的容置空间61内，从而为驱动机构1的结构件提供安装基础与保护基础。壳体60上开设有通孔62，部分手柄支架51贯穿所述通孔62，而其余的手柄支架51则设于壳体60的容置空间61外，设于容置空间61外的手柄支架51用于安装其他结构件，或者直接供用户进行操作。本实施方式可在通孔62的至少部分侧壁开设限位槽63，所述限位槽63与所述手柄支架51相互配合以限制所述手柄支架51的旋转。
如图8与图10所示，手柄支架51上凸设有限位部52，当手柄支架51位于限位槽63内时，限位槽63可限制限位部52的旋转，即壳体60上的限位槽63限制手柄支架51的旋转，此时即为通过壳体60来限制手柄支架51的旋转，从而使齿轮支架50具有固定状态。如图9所示，在手柄支架51朝向齿轮支架50移动的过程中，当限位部52脱离限位槽63或者限位部52脱离通孔62的侧壁范围后，限位槽63便无法再对手柄支架51的限位部52进行限位，这样手柄支架51便可进行旋转，从而带动齿轮支架50进行旋转，从而使齿轮支架50具有旋转状态。
可选地，当要重新使齿圈21固定时，可再将手柄支架51沿远离齿轮支架50的方向移动，并使限位部52重新设于限位槽63内，从而限定手柄支架51的旋转，进而依次限定齿轮支架50与齿圈21的旋转。
请一并参考图11，图11为本申请又一实施方式中驱动机构沿A-A方向的截面示意图。本实施方式中，所述驱动机构1还包括弹性件53，所述弹性件53的一端抵接所述手柄支架51，所述弹性件53的另一端抵接所述齿轮支架50，当所述手柄支架51朝向靠近所述齿轮支架50的方向移动时，所述弹性件53处于压缩状态。
在本实施方式中，还可增设弹性件53，通过弹性件53来连接手柄支架51与齿轮支架50。当所述手柄支架51朝向靠近所述齿轮支架50的方向移动时，所述弹性件53处于压缩状态。此时弹性件53内会具有反弹力，当撤去手柄支架51上的外力后，手柄支架51可在弹性件的反弹力的作用下，使手柄支架51自动沿远离齿轮支架50的方向移动，并使限位部52重新设于限位槽63内，从而限定手柄支架51的旋转，进而依次限定齿轮支架50与齿圈21的旋转。
可选地，所述手柄支架51靠近所述齿轮支架50的一侧开设有第一收容槽54，部分所述弹性件53设于所述第一收容槽54内。本实施方式还可在手柄支架51上靠近所述齿轮支架50的一侧开设有第一收容槽54，并使部分所述弹性件53设于所述第一收容槽54内，这样不仅可提高对弹性件53的限位能力，还可减少驱动机构1的尺寸，简化机构。
请再次参考图7，本实施方式中，所述电机10设于所述行星轮22组件的第一侧24，所述齿轮支架50设于所述行星轮22组件的第二侧25，所述第一侧24与所述第二侧25相对设置。
从上述内容可知，本实施方式提供的驱动机构1可包括电机10、行星轮22组件、以及支架组件。对于这三者的排列关系。所述电机10设于所述行星轮22组件的第一侧24，所述支架组件设于所述行星轮22组件的第二侧25，且所述第一侧24与所述第二侧25相对设置。也可以理解为电机10与支架组件设于行星轮22组件的相对两侧，这样可增加驱动机构1在长度方向的尺寸，降低在厚度方向的尺寸，从而使驱动机构1近似于长而窄的形状。
请一并参考图12-图13，图12为本申请又一实施方式中驱动机构沿A-A方向的截面示意图。图13为本申请另一实施方式中驱动机构的俯视图。本实施方式中，所述驱动机构1还包括万向节70，所述万向节70旋转连接于所述保持架30的另一侧；所述保持架30具有第一旋转方向，所述万向节70具有第二旋转方向，所述第一旋转方向相交于所述第二旋转方向；所述万向节70上开设有第二收容槽71，所述第二收容槽71用于连接锁芯。
从上述内容可知，门锁中的另外一个结构件锁芯连接于保持架30的另一侧，其锁芯与行星轮22组件分别设于保持架30的相对两侧。其锁芯最好垂直连接于保持架30，从而使驱动机构1与锁芯在对接及联动过程中同心，进而使保持架30上的力更好地传导给锁芯，从而降低开锁的难度。因此本实施方式可在驱动机构1中增设万向节70，使万向节70旋转连接于所述保持架30的另一侧，并在万向节70上开设第二收容槽71，利用第二收容槽71来连接锁芯。
另外，保持架30具有第一旋转方向(如图13中D3方向所示)，所述万向节70具有第二旋转方向(如图12中D4方向所示)，所述第一旋转方向相交于所述第二旋转方向。也可以理解为第一旋转方向不平行于第二旋转方向。这样当将锁芯安装于第二收容槽71内时，可利用万向节70的旋转来抵消锁芯与保持架30偏转的角度，从而使保持架30上的力更好地传输给锁芯，修正和解决驱动机构1与锁芯在对接及联动过程中的不同心问题。
请一并参考图14-图15，图14为本申请一实施方式中万向节沿第一子旋转方向旋转时 的示意图。图15为本申请一实施方式中万向节沿第二子旋转方向旋转时的示意图。本实施方式中，所述保持架30的另一侧表面凸设有凸起部72，所述凸起部72围设形成第一旋转空间73，所述万向节70包括第一旋转部74、及第二旋转部75，所述第一旋转部74设于所述第一旋转空间73，且所述第一旋转部74旋转连接所述凸起部72。所述第一旋转部74内具有第二旋转空间76，所述第二旋转部75设于所述第二旋转空间76内，且所述第二旋转部75旋转连接所述第一旋转部74，所述第二旋转部75内具有所述第二收容槽71。所述第一旋转部74具有第一子旋转方向，所述第二旋转部75具有第二子旋转方向，所述第一子旋转方向相交于所述第二子旋转方向，且所述第一子旋转方向与所述第二子旋转方向均相交于所述第二旋转方向。
在本实施方式中，保持架30上可凸设凸起部72，并使万向节70的第一旋转部74、及第二旋转部75设于凸起部72内的第一旋转空间73，并使所述第一旋转部74旋转连接所述凸起部72，进而使第一旋转部74与凸起部72通过旋转轴78平行过度配合连接。这样便可使第一旋转部74具有第一子旋转方向(如图14中D5方向所示)。其次还可使第二旋转部75设于第一旋转部74内的第二旋转空间76，并使所述第二旋转部75旋转连接所述第一旋转部74，以使第二旋转部75与第一旋转部74通过旋转轴78垂直过渡配合连接。这样第二旋转部75便具有了第二子旋转方向(如图15中D6方向所示)。在第二旋转部75内设置用于连接锁芯的第二收容槽71。
上述实施方式提及的第二旋转方向可由第一子旋转方向与第二子旋转方向复合而成。并且本实施方式还可使所述第一子旋转方向相交于所述第二子旋转方向，且所述第一子旋转方向与所述第二子旋转方向均相交于所述第二旋转方向。这样可使万向节70具有更多的旋转方向，从而进一步修正和解决驱动机构1与锁芯在对接及联动过程中的不同心问题。
可选地，请再次参考图13，本实施方式中，所述凸起部72上开设有过孔77，所述万向节70还包括旋转轴78与保护部79，所述旋转轴78贯穿所述过孔77并连接所述第一旋转部74，所述保护部79套设所述凸起部72以使所述旋转轴78抵接所述保护部79
上文提及第一旋转部74可旋转连接于凸起部72上，此时凸起部72上开设有过孔77，旋转轴78贯穿所述过孔77并连接所述第一旋转部74，从而使第一旋转部74旋转连接凸起部72。本实施方式还可在凸起部72外设置保护部79，并使所述保护部79套设所述凸起部72以使所述旋转轴78抵接所述保护部79，从而防止旋转轴78从过孔77中掉落。
本申请实施方式还提供了一种门锁，所述门锁包括锁芯、及如本申请上述实施方式提供的驱动机构1，所述锁芯连接于所述保持架30的另一侧，所述锁芯在所述保持架30的旋转下运动，从而实现开关门。
本申请实施方式提供的门锁，通过采用本申请上述实施方式提供的驱动机构1，可实现通过采用电机10控制齿圈21旋转，或者通过控制太阳轮23旋转两种方式来实现开关门，增加了控制门锁的方法，避免了单一的电机10锁中因电机10损坏而无法开关门的问题，降低了开门的难度与风险性。
以上对本申请实施方式所提供的内容进行了详细介绍，本文对本申请的原理及实施方式进行了阐述与说明，以上说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
