Description

折叠锁定机构 技术领域
本申请涉及一种折叠车，尤其涉及一种折叠车的折叠锁定机构。
背景技术
现有的折叠式电动车的收折方式一般为两种，一种手动折叠，另一种自动折叠；手动折叠的电动车是通过将各个杆件及机构联动设计，使用者只需要简单操作即可实现收折，使用简单。而自动折叠的电动车通常是通过在车上设置驱动装置，利用驱动装置驱动车架收折，使用也十分简单，但是，由于现有的折叠车大多数都没有设置安全机构，折叠车收折后容易发生意外打开的情况，从而会导致意外的事故，因此，现有的折叠车安全性略显不足。另外，现有的折叠车要么只能手动折叠，要么只能自动折叠，折叠方式单一，而一种折叠方式难以适用于全部人群，功能不足。

再请参阅图3及图4，所述折叠锁定机构104包括锁定件1、卡合件2、释锁件3、第一弹性件4、牵引件5、第二弹性件6及松脱开关7，所述锁定件1固定于所述前车架101，所述锁定件1设有锁定部11，所述锁定部11为一通孔，所述卡合件2枢接于所述后车架102，所述卡合件2呈弯折形状，弯折处为枢接点，所述卡合件2的前段设有扣合部21，所述扣合部21为一凸起块，所述第一弹性件4设置于所述后车架102与所述卡合件2的后端之间，并提供一弹性力以使所述扣合部21扣合于所述锁定部11；所述锁定件1的中部两侧向上延伸出枢接部，所述释锁件3的中部枢接于所述枢接部，所述释锁件3的一端抵顶所述卡合件2的端部，以使所述扣合部21脱离所述锁定部11。所述牵引件5的一端连接于所述释锁件3的另一端，以驱动所述释锁件3。设置于所述牵引件5可以实现长距离操作所述释锁件3，增强操作的便利性。所述第二弹性件6设置于所述锁定件1及所述释锁件3之间，所述第二弹性件6提供一使所述释锁件3脱离与所述卡合件2抵触的弹性力。通过设置所述第二弹性件6，可以使所述释锁件3自动复位，从而保证所述卡合件2能再次与所述锁定件1扣合。所述松脱开关7与所述牵引件5的另一端连接，且所述松脱开关7设置于折叠车100的方向杆上，所述松脱开关7可以驱动所述牵引件5，从而使操作更加便利。
再如图4及图5所示，所述电动推杆103与所述后车架102之间设有对所 述电动推杆103限位的定位机构8。所述定位机构8包括枢接件81、第一扣件82、第二扣件83及第三弹性件84，所述枢接件81的一端枢接于所述后车架102，所述枢接件81的另一端与所述电动推杆103的缸体端部枢接，所述第一扣件82的中部枢接于所述后车架102，且所述第一扣件82开设有限位开口82a，所述枢接件81延伸出轴销81a，所述限位开口82a与所述轴销81a扣合，所述第二扣件83的一端枢接于所述后车架102，所述第二扣件83的另一端延伸到所述释锁件3的上方，并在所述释锁件3顶开所述卡合件2后与所述释锁件3抵顶；所述第三弹性件84连接于所述第一扣件82及第二扣件83之间，以使所述第一扣件82及第二扣件83相互扣合，从而限制所述电动推杆103的缸体移动。通过设置所述枢接件81，使所述枢接件81延伸出轴销81a，并使其与所述电动推杆103枢接，又在第一扣件82上开设限位开口82a，使限位开口82a与所述轴销81a扣合，从而通过枢接于后车架102上的第一扣件82及第二扣件83相互扣合或松开而使所述枢接件81锁定或释锁，达到对所述电动推杆103进行限位或者释放的目的，使所述电动推杆103在限位时只能沿枢接中心转动而不能摆动，在释放后则可进行摆动，从而无论所述电动推杆103的伸缩杆处于伸长或缩短的任一状态下，均可对所述前车架101及后车架102进行收折，提高收折的灵活性及可靠性，使操作更方便。具体地，所述第一扣件82设有第一齿部82b，所述第二扣件83设有第二齿部83a，所述第一扣件82及第二扣件83相互扣合时，所述第一齿部82b与所述第二齿部83a相互抵顶。通过设置所述第一齿部82b及第二齿部83a，从而可以使所述第一扣件82及第二扣件83实现自锁，达到对所述枢接件81限位的目的。
再如图4及图5所示，所述折叠锁定机构104还包括遥控发射器(图中未示)、遥控接收器及控制器，所述遥控接收器与所述控制器电连接，所述控制器与所述电动推杆103电连接，所述遥控发射器通过遥控接收器及控制器控制所述电动推杆103的启停；设置所述遥控发射器及遥控接收器可以使所述折叠车100遥控自动收折，使用方便。另外，所述枢接件81设有顶推杆81b，所述顶推杆81b与所述卡合件2的下边缘抵顶。
综合上述并结合图6及图7，下面对本申请的折叠车100的展开及折叠原理 进行详细描述，如下：
当所述折叠车100处于折叠且所述电动推杆103处于收缩状态时，手动或自动切换机构对活塞杆不限位，此状态可手动打开车架，之后手动折叠车100架；折叠车100打开时，手动操作所述松脱开关7，使所述松脱开关7带动所述牵引件5拉紧所述释锁件3的一端，所述释锁件3沿枢接中心转动，所述释锁件3的另一端向上抬起，抬起时顶推所述卡合件2的端部，这时，所述卡合件2向上转动，所述扣合部21即离开所述锁定部11，所述卡合件2与所述锁定件1解锁，所述前车架101及所述后车架102即处于释锁状态，此时即可将所述前车架101及后车架102展开。收折时，直接将所述前车架101及所述后车架102靠拢，当所述锁定件1与所述卡合件2靠近时，通过所述锁定件1端部的导向斜面及所述第一弹性件4的弹性力作用使所述扣合部21扣合于所述锁定部11内，从而再次将所述前车架101及后车架102锁定于收折状态。
当所述折叠车100处于折叠且所述电动推杆103处于伸长状态时，手动或自动切换机构对活塞杆限位，此状态可手动打开车架，之后手动折叠车100架；折叠车100打开时，手动操作所述松脱开关7，使所述松脱开关7带动所述牵引件5拉紧所述释锁件3的一端，所述释锁件3沿枢接中心转动，所述释锁件3的另一端向上抬起，抬起时顶推所述卡合件2的端部，这时，所述卡合件2向上转动，所述扣合部21即离开所述锁定部11，所述卡合件2与所述锁定件1解锁；当将所述松脱开关7按压到底时，所述锁定件1的另一端继续向上抬起并顶推所述第二扣件83，所述第二扣件83向上转动，这时，所述第二齿部83a脱离所述第一齿部82b，从而使所述第二扣件83与所述第一扣件82解锁，并且，在所述第二弹性件6的拉力作用下，所述第一扣件82向上转动而使所述限位开口82a与所述轴销81a脱离，从而使所述第一扣件82与所述枢接件81解锁；此时，所述电动推杆103的缸体即处于放松状态，这时，即可将所述前车架101及后车架102展开。收折时，直接将所述前车架101及所述后车架102靠拢，当所述锁定件1与所述卡合件2靠近时，通过所述锁定件1端部的导向斜面及所述第一弹性件4的弹性力作用使所述扣合部21扣合于所述锁定部11内，从而再次将所述前车架101及后车架102锁定于收折状态。另外，当所述折叠车 100处于折叠且所述电动推杆103处于伸长状态时，手动或自动切换机构对活塞杆限位，此状态也可以先手动解锁所述前车架101及后车架102，而所述定位机构8不对所述电动推杆103解锁，这时便可启动所述电动推杆103，使所述电动推杆103收缩，从而通过所述电动推杆103自动打开所述折叠车100。
当所述折叠车100处于折叠且所述电动推杆103处于伸长状态时，手动或自动切换机构对活塞杆限位，此状态可自动打开车架，之后自动折叠车100架；所述折叠车100打开时，通过遥控发射器对所述遥控接收器发送打开指令，所述遥控接收器即通过所述控制器控制所述电动推杆103启动，使所述电动推杆103收缩，这时，所述电动推杆103的缸体带动所述枢接件81向上转动，从而带动所述顶推杆81b向上移动，所述顶推杆81b顶推所述卡合件2，所述卡合件2的扣合部21脱离所述锁定部11，以使所述前车架101及所述后车架102解锁，解锁后，所述电动推杆103继续收缩，从而驱动所述前车架101及所述后车架102打平实现展开整个折叠车100。当收折时，通过遥控发射器对所述遥控接收器发送收折指令，所述遥控接收器即通过所述控制器控制所述电动推杆103启动，使所述电动推杆103伸出，从而带动所述前车架101及后车架102靠拢，从而达到对所述折叠车100收折的目的。
由于本申请通过在所述前车架101设置锁定件1、在所述后车架102设置卡合件2，并在所述第一弹性件4设置于所述后车架102与所述卡合件2之间，通过所述第一弹性件4弹性力使所述锁定件1上的锁定部11与所述卡合件2上的扣合部21相互扣合，从而使所述前车架101及所述后车架102在相互靠拢时处于锁定状态，防止折叠车100收折后意外展开；并且通过设置所述释锁件3，通过操作所述释锁件3与所述卡合件2抵顶，进而使扣合部21脱离所述锁定部11，实现对所述前车架101及所述后车架102解锁，使两者能相互展开；因此本实新型结构简单，操作方便，安全性高。并且，又通过设置所述定位机构8，利用所述定位机构8对所述电动推杆103的限位或释放，从而使得所述电动推杆103无论处于何种状态均可通过手动或自动任一者的收折方式收折车架；另外，又通过设置所述遥控发射器及所述遥控接收器对所述电动推杆103进行自动控制，从而可以使使用者遥控折叠车实现自动收折；通过上述多种收折方式的结合从 而有效增强了折叠车收折的功能性，适合全部人群使用。
以上所揭露的仅为本申请的较佳实例而已，当然不能以此来限定本申请之权利范围，因此依本申请申请专利范围所作的等同变化，仍属于本申请所涵盖的范围。
