Description

动平衡车用操控机构 技术领域
本发明涉及动平衡车技术领域，特别涉及一种动平衡车用操控机构。
背景技术
动平衡车目前成为了流行的短途代步工具，包括单轮动平衡车和双轮动平衡车。目前市场上出现的双轮动平衡车主要包括手控型和腿控型两种车型。
手控型的双轮动平衡车通过手动操纵设置在车体上的转向杆上的把手而控制动平衡车的行驶。这种手操控型的动平衡车由于容易保持平衡度，骑行者能够迅速掌握骑行技巧，因此得到了广泛的流行。然而，这种手控型的动平衡车对手的约束较大，束缚了双手，使得骑行者很难在骑行过程中，用手去做别的事情。而且由于转向杆相对较长，在不骑行的状态下，不方便拖行。
腿控型的双轮动平衡车通过两腿夹住设置在腿控杆上腿控垫来控制腿控杆，进而控制动平衡车的行驶。腿控型的双轮动平衡车的一大特点就是能够解放双手，在车辆骑行过程中，骑行者的双手可以有足够的自由空间，去做别的事情。然而，这种腿控型的动平衡车的腿控长度都是唯一固定的，一定长度的腿控杆只能适用具有一定高度的人群。另外的一大部分人群，由于身高、体型等原因，就无法正常骑行车辆，或是骑行过程中，由于腿控位置的高度不合适，大大影响骑行的舒适度。而且，在不骑行状态下，由于腿控杆的高度相对较低，这种适合腿部控制的长度并不太适合手进行推拉，骑行者在正常行走的情况下，无法舒适的拖动车辆的行走，这样，就给户外的骑行带来很大的不便。
目前的双轮动平衡车，只能是手控和脚控二者选一，但是在户外骑行过程中，由于户外环境较为复杂，有些地方使用把手操作比较方便，可是有些地方，通过腿部控制更会方便，这种情况下，会给户外的骑行带来很大的不便。骑行者需要同时带着手控杆和腿控杆，才能适应需要手控和腿控的情况，拆下手控杆，装上腿控杆，或是拆下腿控杆，更换为手控杆，这样将会给出行带来非常的不方便，而且会增加经济成本。
因此，非常期待出现一种能够同时适合手部操作、腿部操作和非骑行状态下拖行，也能适合不同人群操作的双轮动平衡车的出现。

本发明的实施例的操控机构用于安装在动平衡车车体上，尤其是双轮动平衡车上，与车体上的转向机构连接，用于控制车体的行驶，包括骑行状态下的转向和非骑行状态下的拖行，如图6和7所示。操控机构的一端头直接固定在车架或者车体的其他位置处，车架的上固定有轮胎，在车架的两侧设置有轮罩，轮毂或轮罩中设置有控制组件和电源组件，如图8所示。本发明的实施例对安装的车体并没有特别限制，可为现有技术中所公开的车体结构。例如，可为中国专利申请号为201210421265.X、公开日为2013年1月16日；申请号201410385053.X、公开日为2014年10月29日；以及申请号201320666169.1、公告日2014年5月21日所公开的车体结构，在此不再赘述。
本发明的实施例的操控机构能够根据骑行状况选择不同的操作模式。骑行者可选择通过腿部操作来控制车体转向，也可选择通过手部操作来控制车体转向，也可以在非骑行状态下，通过调节操控机构的高度来舒适的拖行车体，以下参考附图对发明的实施例的操控机构进行介绍。
实施例1
图1为本实施例的操控机构的结构示意图。如图1所示，本发明的实施例的操控机构可包括杆体1、连接座2、腿控垫3、拉杆4和把手5。
杆体1可为中空结构，内部形成有供拉杆4滑动的滑动空间(未图示)，滑动空间具有第一位置和第二位置(未图示)，杆体1的上端部与连接座2连接，杆体1的下端部与车体20的转向机构连接(参考图6和7)，杆体1转动时带动转向机构转动，以控制车体20的转向。第一位置可为拉杆4处于非伸缩状态时，拉杆4最底端与滑动空间接触的位置，第二位置可为拉杆4处于完全伸缩状态时，即拉杆4拉伸到极限位置时，拉杆4最底端与滑动空间接触的位置，即，第一位置和第二位置分别是向下推拉杆4和向上拉拉杆4所能达到的极限位置。为增强美观和可操纵性，杆体1的下端可形成为稍微弯曲的形状，上端可为直筒结构。
连接座2可通过螺钉与拉杆1的上端连接，在连接座2的两侧固定连接有两个腿控垫3。腿控垫3可形成为适合两腿内侧夹持的形状，通过腿部夹持腿控垫3，可带动杆体1转动，进而可控制车体20的转向。在连接座2上形成有开口，拉杆4通过该开口进入滑动空间。
拉杆4容纳在该滑动空间中，沿滑动空间可伸缩地滑动并限位于滑动空间，以在第一位置和第二位置之间的滑动空间滑动。拉杆4可通过限位结构限位于滑动空间中，以使得拉杆4不会没入或脱离滑动空间。在本发明的实施例的一示例结构中，可在拉杆4的下端套设限位件，在滑动空间上的第一位置和第二位置之间间隔设置有若干个限位孔。限位件可包括限位套、弹簧和限位珠(可参考图3的附图标记13、18和19所示结构)，限位套上形成凹孔，凹孔内埋设有弹簧，弹簧上放置限位珠。当拉杆4位于第一位置时，限位珠嵌入位于第一位置处的限位孔中，与该限位孔卡合，当拉杆4位于第二位置时，限位珠嵌入位于第二位置处的限位孔，与该限位孔卡合，以将拉杆4固定在滑动空间中。当拉杆4在第一位置和第二位置之间滑动时，由于受到拉力的作用，限位珠会挤压弹簧，缩回凹孔处，当拉杆4拉到期望的高度时，拉力解除，限位珠在弹簧的作用下，与滑动空间内壁接触，实现拉杆4的固定。即，限位珠一方面起到限位的作用，另一方面也起到引导拉杆4在滑动空间滑动的作用。由于设置有多个限位孔，因此，可将拉杆4拉至不同的高度，以满足不同高度的人群对拉杆高度的需求。此外，为使得拉杆4能够足够长，拉杆4可采用套结结构，即拉杆4可包括第一拉杆和嵌套在第一拉杆中的第二拉杆。拉杆4的拉出长度与杆体1的高度以及车体本身的高度之和，适合具有正常身高的人群。
由于限位珠与弹簧是活动连接，当施加较大的拉力时，限位珠与限位孔的卡合会脱离，这样拉杆4容易从滑动空间中脱离，因此，为避免拉杆4脱离滑动 空间，可设置防脱离机构。可采用任何能够防止拉杆4从滑动空间脱离的结构，本发明的实施例示出了一简单的防脱离结构，但并不限于此。根据本发明的实施例的一示例结构，可在拉杆4的长度方向上形成具有限位端的长凹槽，在滑动空间中比第二位置高的位置处设置一通孔，即在杆体1上形成通孔，然后通过该通孔插入限位柱(限位销)，限位柱位于凹槽中，这种通过限位柱和凹槽配合的结构，结构简单，且不会占用很大空间。由于杆体1的上端固定连接连接座2，即连接座2会盖住限位柱，这样当向上拉出拉杆4时，限位柱在凹槽中经过，待拉杆4处于第二位置时，限位柱与凹槽的下限位端卡合，即卡在凹槽的最下端，对拉杆4形成约束力，防止拉杆4从滑动空间中拉出。当拉杆4处于第一位置时，限位柱卡在凹槽的最上端，对拉杆4形成约束力，防止拉杆4没入滑动空间中。
把手5套接在拉杆4的顶端，通过操作把手5，可引导拉杆4在滑动空间中滑动。操作把手5可带动杆体1的转动，把手5可为适合手握或推拉的形状，图1示出的把手5的形状为适合推拉的形状。当不使用把手5时，可将把手5放置在两个腿控垫3之间的位置。当把手5采用适合双手把握的形状时，例如一字型形状，当使用把手5时，在将拉杆4拉出后，可顺时针或逆时针转动把手5，以使得把手5适合骑行者把握。
本发明的实施例对杆体1和拉杆4的形状并没有限制，例如杆体1和拉杆4的截面形状可为三角形、圆形、棱形、四边形等等。
根据本实施例的操控机构，可同时实现腿控操作和手控操作的功能。在使用本实施例的操控机构时，将组装好的操控机构通过锁紧机构安装在车体20上。例如可通过锁紧螺母或者卡合结构21将操控机构安装在车体20上。在户外骑行时，当需要腿部操作时，可将拉杆4拉至最低处，将把手5放置在腿控垫3形成的空间中，当需要变更为把手5操作时，可拉动把手5将拉杆4拉出至适合把握或拖拉的高度即可。
实施例2
本实施例的操控机构与实施例1的操控机构具有大致相同的结构，不同的是，本实施例的操控机构的杆体的高度可调节。图2是本实施例的操控机构的结构示意图。如图2所示，本发明的实施例的操控机构可包括杆体、连接座2、腿控垫3、拉杆4和把手5。连接座2、腿控垫3和把手5的结构与实施例1所描述的结构相同，在此避免赘述，省略相关描述。
在本实施例中，杆体包括分离设置的上杆体9和下杆体6，上杆体9和下杆体6之间的高度可调节。上杆体9和下杆体6之间嵌套有支撑杆7，支撑杆7的一端嵌套并固定在下杆体9的内部，另一端嵌套并滑动设置于上杆体6的内部，上 杆体9沿支撑杆7滑动以调节上杆体9和下杆体6之间的高度，并限位于支撑杆8。为增强美观和可操纵性，下杆体6可形成为稍微弯曲的形状，上杆体9可为直筒结构。
具体地，如图3所示的分解图所示，在下杆体6的上端套设有固定套10，支撑杆7的下端套入固定套10中与下杆体6连接，可通过螺钉将支撑杆7固定在下杆体6上。在上杆体9的下端套设有固定套16，在支撑杆7的上端套设有固定套12，当支撑杆7从上杆体9上端套入后，固定套12的下端面与固定套16的上端面相卡合，固定套16的上端面限制支撑杆7穿过上杆体9，防止上杆体9与支撑杆7脱离。可通过锁定部件8将上杆体9定位在支撑杆7上，锁紧组件8处于松脱状态时，上杆体9可沿支撑杆7滑动以调节上杆体9和下杆体6之间的高度，锁紧组件8处于锁紧状态时，上杆体9固定于支撑杆7。在本实施例的一示例结构中，如图3所示，锁定部件8可包括锁定座14、垫片和锁定螺母15。锁定座14上形成有安装螺母15的通孔，在锁定座14朝向上杆体9内部的一端设置有放置垫片的凹孔，凹孔形成在该通孔的端部，在上杆体9的下端设置有安装锁定座14的安装孔，该垫片与固定套16的侧面接触。当上杆体9滑动到支撑杆7的所需高度时，拧紧锁定螺母15，螺母15通过垫片与固定套16的侧面抵接，实现上杆体9与支撑杆7之间的固定。固定套10、12、16可为塑料材质。通过固定套来实现上杆体9和支撑杆7之间的限位，这种限位方式操作方便，且容易制作。
在本实施例中，拉杆4通过延伸杆，如拉杆支撑套12在滑动空间中滑动。拉杆支撑套12的宽度比支撑杆7的宽度小，比拉杆4的宽度大。拉杆支撑套12的至少一部分套入支撑杆7的内部，拉杆支撑套12和支撑杆7的内部空间共同形成供拉杆4滑动的滑动空间。拉杆4可通过限位机构限位在滑动空间中，以使得拉杆4不会没入或脱离滑动空间。例如，可在拉杆4的一端设置有与上述实施例1所描述的限位件，即限位件可包括限位套13、弹簧19和限位珠18，限位套13上形成凹孔，凹孔内埋设有弹簧19，弹簧19上放置限位珠(滚珠)18。在拉杆支撑套12上形成若干个限位孔，本实施例中示出为3个，以地面为基准，按照拉杆支撑套的长度方向排序，依次称为第一、第二和第三限位孔。当拉杆4位于第一位置时，限位珠18嵌入第一限位孔中，与该限位孔卡合，当拉杆4位于第二位置时，限位珠嵌入第二限位孔中，与该限位孔卡合，以将拉杆4固定在滑动空间中。
本实施例中，第三限位孔用于通过限位柱17。与实施例1相同，可通过限位柱17来防止拉杆4与滑动空间的脱离，可在拉杆4上形成与实施例1相同的凹槽结构。为形成滑动空间，拉杆支撑套12可随着上杆体9一起运动，它们之间可通过限位柱17进行连接。为此，在上杆体9上形成有与第三限位孔相对应的 通孔，限位柱17穿过通孔、第三限位孔，进入凹槽中，以将拉杆支撑套12与上杆体9连接起来，当上杆体9沿支撑杆7滑动时，拉杆支撑套12随着上杆体9一起运动，即拉杆支撑套12相对于上杆体9处于静止状态。这样，限位柱17一方面起到将拉杆支撑套12固定在上杆体9上以形成滑动空间，另一方面起到防止拉杆4从滑动空间脱离的作用。
根据本实施例的操控机构，可同时实现腿控操作和手控操作的功能。在使用本实施例的操控机构时，将组装好的操控机构通过锁紧机构安装在车体20上。例如可通过锁紧螺母或者卡合结构21将操控机构安装在车体20上。在户外骑行时，当需要腿部操作时，可将拉杆4拉至最低处，将把手5放置在腿控垫3形成的空间中，如图4所示。当需要变更为把手5操作时，可拉动把手5将拉杆4拉出至适合把握或拖拉的高度即可，也可同时调节杆体的高度，以满足不同的高度需求。此外，当需要不同的腿控高度时，可调节杆体的高度，可将上杆体9沿支撑杆7滑动至适当的高度，如图5所示，这样可满足具有不同身高的人群的需求。
图6和图7是安装有本实施例的操控机构的双轮动平衡车示意图。图6是同时调节杆体高度和拉杆长度的示意图，图7是没有调节杆体高度和拉杆长度的示意图。
上述说明示出并描述了本发明的若干优选实施例，但如前所述，应当理解本发明并非局限于本文所披露的形式，不应看作是对其他实施例的排除，而可用于各种其他组合、修改和环境，并能够在本文所述发明构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围，则都应在本发明所附权利要求的保护范围内。
