Description

一种带有自动锁定功能的折叠电动健身车 技术领域
本实用新型属于交通工具领域，具体涉及一种带有自动锁定功能的折叠电动健身车。
背景技术
技术
随着社会发展与科技进步，人们对于出行交通工具快速、便捷、环保等各方面的要求也越来越高，现有的折叠交通工具，通常体积较大，重量过重，对停放场地有一定的要求，且携带不方便、容易被盗，使用、停放、携带、存储、安全等方面存在诸多不便。
现有的折叠式交通工具其折叠方式多是手动折叠，折叠过程中通常需要先手动解锁折叠关节处的锁扣，然后将车架折叠，为避免携带运输过程中车架散开，车架折叠到位之后需要再将相应关节锁定，整车折叠过程较为复杂，操作步骤多，程序繁琐，另外还存在折叠后体积缩减效果不明显、重量过重、携带不方便、外观陈旧单一等诸多问题。
如何研发一种自动化程度高的折叠式交通工具，成为本领域技术人员亟需解决的技术难题。
技术问题
为克服上述缺陷，本实用新型所要解决的技术问题是：设计一种带有自动锁定功能的折叠电动健身车，实现整车折叠、展开的自动化解锁、锁定。
问题的解决方案
技术解决方案
要解决其技术问题，所采用的技术方案是：设计一种带有自动锁定功能的折叠电动健身车，包括前把架、折叠底盘和折叠轮架，其特征在于，所述前把架的内部空间设置电池电源，用于整车的动力驱动，折叠底盘设置折叠轴，折叠轮架相应的设置与之适配的轴套，轴与轴套之间设置棘轮，所述棘轮的顶珠通过 连杆连接用以锁定底盘和前把架的弹性锁销，前把架固定连接轴座，底盘与轴座转动连接，所述锁销设置于底盘底部，与之对应的销孔分别设置于轴座底端和顶端，所述连杆有一支臂设置防止锁销回弹的卡锁，所述卡锁替换为限位挡装置，所述限位挡装置包括设置于轴套的两个卡槽，还包括连杆一支臂设置的与卡槽适配的弧形钩，所述支臂与弧形钩相背的一侧设置侧翅，所述支臂设置侧翅一端穿入一约束环，该约束环设置于底盘后端的下卷沿，所述棘轮包括带有上下齿牙的扳动柄，所述扳动柄设有尖角与顶珠相抵，所述连杆通过一圆柱形通道与顶珠相顶，所述连杆通过活动轴设置于折叠底盘，所述连杆有一支臂设置卡扣，折叠轮架设置相应的卡孔，所述卡扣与卡孔相适配，所述锁销包括弹簧。
发明的有益效果
有益效果
本实用新型所具有的有益效果包括：
1、该车折叠、展开的自动化解锁、锁定，无需过多的手动操作，展开状态打开棘轮扳动柄，后轮架与底盘解锁，同时通过连杆的联动作用控制锁销使得前把架与底盘也解锁；折叠到位时，后轮架与底盘锁定，同时前把架与底盘也自动锁定，锁定后车架不会散开，携带运输方便安全，体积小，占用空间少，携带方便。
2、所述棘轮的顶珠通过连杆连接用以锁定底盘和前把架的弹性锁销，连杆可以把顶珠的活动行程传导到弹性锁销，每次操作扳动柄顶珠都会发生一定的位移，该位移行程通过连杆的传导造成锁销从销孔内拔出。
3、折叠轮架与折叠底盘通过棘轮轴连接，既实现了打开扳动柄时二者可以折叠，又实现了折叠时运动方向的单向性；折叠过程随时可暂停不会自动回转，保证了折叠到位时自动锁定。
4、所述连杆通过一圆柱形通道与顶珠相顶，棘轮结构中安放顶珠的孔洞被延伸为一圆柱形通道，从弹性锁销方向而来的连杆绕过棘轮结构穿入该圆柱形通道与顶珠相顶，这样每次顶珠发生向后的位移，都会顶的锁销发生向后的位移。而且该设计使得顶珠的缓冲性和弹性大为增强。
5、所述连杆有一支臂设置防止锁销回弹的卡锁，当锁销被从锁孔内拉出解锁的时候到开始折叠之间有一很短的时间差，该时间差虽然短但如果没有卡锁足够锁销自动回弹入销孔内，使用极为不便。该卡锁专为解决折叠前锁销自动回弹而设。
所述连杆有一支臂设置卡扣，折叠轮架设置相应的卡孔，所述卡扣与卡孔相适配，当锁销向后运动时，相应的该连杆支臂也向后运动，当支臂上的卡扣运动到折叠轮架的卡孔时，卡扣卡孔锁定在一起，锁销也相应的无法自动回弹了。
当折叠开始时，折叠轮架跟着运动，则卡孔脱离卡扣的位置，虽然锁销在弹簧作用下可以自动回弹，但此时锁销也因为底盘的折叠脱离了原来锁孔的位置，无法插入锁销，自然也就无妨了。
并且，这种锁销的自动回弹力，在折叠到位时又会起到重要的作用：当折叠到位时，锁销恰好转到轴座顶端锁孔的位置，锁销自动弹入锁孔内，折叠底盘和前把架在折叠状态下又被锁定在一起。
6、所述锁销设置于底盘底部，与之对应的销孔设置于轴座，锁销插入销孔可以实现底盘和前把架的锁定；解锁时，底盘和前把架可以折叠，锁销可以在轴座上沿弧形滑动。
7、该设计充分利用车体或配件的内部空间，保证整车外观流畅，结构简单，稳定性安全性高，功率损失少，能量利用率高，使用顶珠连接连杆、连杆连接锁销的方式，功能稳定，联动效果好，配件更换容易且成本低。

实施该发明的最佳实施例
本发明的最佳实施方式
如图所示，本实用新型一种带有自动锁定功能的折叠电动健身车，包括前把架1、折叠底盘2和折叠轮架3，所述前把架1的内部空间设置电池电源，用于整车的动力驱动，折叠底盘2设置折叠轴，折叠轮架3相应的设置与之适配的轴套，轴与轴套之间设置棘轮4，折叠轮架3与折叠底盘2通过棘轮4轴连接，所述棘轮4的顶珠5通过连杆7连接用以锁定底盘和前把架的弹性锁销6，前把架1固定连接轴座19，底盘与轴座19转动连接，所述锁销设置于底盘底部，与之对应的销孔18分别设置于轴座19底端和顶端，所述连杆7有一支臂8设置防止锁销回弹的卡锁9，所述卡锁9替换为限位挡装置，所述限位挡装置包括设置于轴套的两个卡槽25，还包括连杆一支臂设置的与卡槽25适配的弧形钩24，所述支臂与弧形钩24相背的一侧设置侧翅22，所述支臂设置侧翅一端穿入一约束环23，该约束环23设置于底盘后端的下卷沿，所述棘轮4包括带有上下齿牙的扳动柄10，所述扳动柄10设有尖角11与顶珠12相抵，所述连杆7通过一圆柱形通道13与顶珠5相顶，所述连杆7通过活动轴14设置于折叠底盘2，所述连杆7有一支臂8设置卡扣15，折叠轮架3设置相应的卡孔16，所述卡扣15与卡孔16相适配，所述锁销包括弹簧17，所述锁销设置于底盘底部，与之对应的销孔18设置于轴座19，所述轴座19顶端还设有一销孔18。
整车展开状态，锁销插入销孔18，折叠底盘2和前把架1锁定在一起；扳动柄10的上齿牙20插入棘轮4的棘齿12内，顶珠5从后面顶住尖角11，折叠轮架3与折叠 底盘2也锁定在一起。
需要折叠时，操纵扳动柄10，上齿牙20脱出棘齿12，同时下齿牙21插入棘齿12，此时折叠轮架3被解锁，可以进行折叠轮架2向着折叠底盘2的底面单方向的折叠。在操纵扳动柄10时，尖角11从顶珠5以上运动到顶珠5以下，在这个过程中，顶珠5被迫发生一段位移，相应的连杆7也发生向后的位移，拉动弹性锁销6从销孔18内脱出，连杆7向后运动导致连杆支臂8上的卡扣15运动到折叠轮架的卡孔16时二者锁定在一起，锁销无法自动回弹，此时折叠底盘2和前把架1解锁，可以将折叠底盘2向着车把架1折叠。在折叠过程中，折叠轮架3随着转动离开了原来的位置，相应的卡孔16离开了卡扣15的位置，则弹性锁销6就一直保持着回弹的弹性势能。
在折叠到位时，弹性锁销6运动到轴座19顶端的销孔18，自动弹入销孔18内，在折叠状态下折叠底盘2和前把架1锁定在一起；折叠轮架3向着折叠底盘2底面折叠到位时，因为棘轮4单向运动性，在操纵扳动柄10之前不可能发生回转，二者也自动的锁定在一起。
连杆一支臂设置狐形钩24，从展开状态要折叠时，当锁销从轴座19下端销孔内拨出时，该支臂向后运动，侧翅22沿约束环23向后运动，连杆支臂被侧翅22挤得向设有弧形钩24的一侧偏移，该偏移恰好使得弧形钩24勾住设置于轴套的一卡槽25，锁销无法回弹；当转动折叠轮架3时，卡槽25与弧形钩24分离，解除钩挂。当需要从折叠状态展开时，支臂向后运动，弧形钩24又钩住另一卡槽25，当继续伸展时，弧形钩24再次脱离该卡槽25。
当需要从折叠状态展开时，再次操纵扳动柄10，其下齿牙21脱出棘齿12，同时上齿牙20插入棘齿12，此时折叠轮架3被解锁，同时在连杆7作用下弹性锁销6从轴座19上端的销孔18内脱出，连杆支臂8上的卡扣15与折叠轮架3上的卡孔16锁定在一起，前把架1与折叠底盘2也被解锁，可以进行整车的展开，在展开到位时，恢复到原来的展开状态，整车被锁定。
该折叠式交通工具实现整车折叠、展开的自动化解锁、锁定，无需过多的手动操作，展开状态打开棘轮扳动柄10，折叠轮架3与底盘解锁，同时通过连杆7的联动作用控制锁销使得前把架1与底盘也解锁；折叠到位时，折叠轮架3与底盘 锁定，同时前把架1与底盘也自动锁定，锁定后车架不会散开，携带运输方便安全，体积小，占用空间少，携带方便。
所述棘轮4的顶珠5通过连杆7连接用以锁定底盘和前把架的弹性锁销6，连杆7可以把顶珠5的活动行程传导到弹性锁销6，每次操作扳动柄10顶珠都会发生一定的位移，该位移行程通过连杆7的传导造成锁销从销孔18内拔出。
折叠轮架3与折叠底盘2通过棘轮4轴连接，既实现了打开扳动柄10时二者可以折叠，又实现了折叠时运动方向的单向性；折叠过程随时可暂停不会自动回转，保证了折叠到位时自动锁定。
所述连杆7通过一圆柱形通道13与顶珠5相顶，棘轮结构中安放顶珠5的孔洞被延伸为一圆柱形通道，从弹性锁销6方向而来的连杆7绕过棘轮结构穿入该圆柱形通道13与顶珠5相顶，这样每次顶珠5发生向后的位移，都会顶的锁销发生向后的位移。而且该设计使得顶珠5的缓冲性和弹性大为增强。
所述连杆7有一支臂8设置防止锁销回弹的卡锁9，当锁销被从销孔18内拉出解锁的时候到开始折叠之间有一很短的时间差，该时间差虽然短但如果没有卡锁9足够锁销自动回弹入销孔18内，使用极为不便。该卡锁9专为解决折叠前锁销自动回弹而设。
所述连杆7有一支臂8设置卡扣15，折叠轮架3设置相应的卡孔16，所述卡扣15与卡孔16相适配，当锁销向后运动时，相应的该连杆支臂8也向后运动，当支臂上的卡扣15运动到折叠轮架3的卡孔16时，卡扣15卡孔16锁定在一起，锁销也相应的无法自动回弹了。
当折叠开始时，折叠轮架3跟着运动，则卡孔16脱离卡扣15的位置，虽然锁销在弹簧作用下可以自动回弹，但此时锁销也因为底盘的折叠脱离了原来销孔18的位置，无法插入锁销，自然也就无妨了。
并且，这种锁销的自动回弹力，在折叠到位时又会起到重要的作用：当折叠到位时，锁销恰好转到轴座19顶端销孔的位置，锁销自动弹入销孔18内，折叠底盘2和前把架1在折叠状态下又被锁定在一起。
所述锁销设置于底盘底部，与之对应的销孔18设置于轴座19，锁销插入销孔18 可以实现底盘和前把架1的锁定；解锁时，底盘和前把架1可以折叠，锁销可以在轴座19上沿弧形滑动。
该设计充分利用车体或配件的内部空间，保证整车外观流畅，结构简单，稳定性安全性高，功率损失少，能量利用率高，使用顶珠5连接连杆7、连杆7连接锁销的方式，功能稳定，联动效果好，配件更换容易且成本低。
需要指出的，上述实施方式仅是本实用新型优选的实施例，对于本技术领域的普通技术人员来说，在符合本实用新型工作原理的前提下，任何等同或相似的替换均落入本实用新型的保护范围。
