Description

具有电池盒结构的电动自行车车架管 技术领域
本发明涉及一种电动自行车的部件，具体涉及一种电动自行车的车架管，尤其是具有电池盒结构的车架管。
 背景技术
电动自行车采用可充式电池供电，当电池盒被近竖向设置在座管或前管处时，会占用车体长度方向的位置，导致轮距、踏脚布局方面的问题，因此，越来越多地将电池盒设置在横向车架管中。然而，考虑到车架管的强度问题，现有技术中通常对车架管采用双腔或多腔结构设置，在顶部腔体处开口，形成电池盒的安装结构。此外，也有如中国发明专利申请CN103523133A中所公开的结构：一种电动自行车的车架管，包括：呈中空管状结构的主体管，其中空内腔用以安放电池，在所述主体管的管壁上开设有将电池放入所述内腔中的开口，所述管壁的非开口位置还设置有补强管，所述补强管的长度方向与所述主体管的长度方向一致。
 技术问题
不管是采用在同一车架管中设置隔板构成的双腔或多腔结构，还是采用另设补强管的结构，均需要占用车架管在高度方向的空间，使得安装电池盒结构后的车架管整体高度增加，导致踏板位置相应升高，影响用户骑乘体验。
因此，需要对电动自行车车架管的结构进行改进。
 技术解决方案
本发明的发明目的是提供一种具有电池盒结构的电动自行车车架管，在不占用车架管高度方向空间的前提下，保证车架管的强度。
为达到上述发明目的，本发明采用的技术方案是：一种具有电池盒结构的电动自行车车架管，包括具有中空管状结构的车架管本体，在所述车架管本体上部开设有开口，与所述开口配合设置有电池盒体；所述车架管本体为单管结构，在管体的两个侧壁上分布有肋板，两个侧壁上的肋板边缘之间的距离自上向下缩减，肋板边缘之间的空腔构成电池盒容纳位；所述电池盒体的侧壁形状与所述电池盒容纳位的形状配合。
上述技术方案中，每一所述肋板至少包括沿车架管长度方向延展的水平板，在每一侧壁上设有间隔布置的5～10个所述肋板，上方的肋板的宽度小于下方的肋板，在车架管的横剖面上，自上向下各肋板的边缘的连线构成直线或光滑曲线，两侧板间的上述各连线之间构成上宽下窄的电池盒容纳位。
进一步的技术方案，两侧壁上至少一对所述肋板具有从水平板边缘沿所述连线的方向向侧下方延展构成的侧板。
优选的技术方案，位于最下方的一对肋板具有所述水平板和所述侧板；其它肋板仅由水平板构成。
上述技术方案中，所述电池盒体与所述车架管本体上的电池盒容纳位一端构成旋转连接配合，与另一端的车架管本体之间设有锁定结构。
优选地，所述电池盒体与车架管本体的锁定结构一端之间设有弹片结构，在锁定结构解锁时，所述弹片结构将电池盒体一端弹出。
 有益效果
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
本发明中，通过设置一组肋板，且电池盒体与肋板外缘间形状配合，使得电池盒体的重量被多个肋板分摊后传递到侧板上，整个车架管本体受力均匀，因而不需要在底部设置双管结构，不会占用车架管的高度空间；由此，本发明在保证车架管整体受力安全的前提下，降低了车架管的占据高度，便于脚踏布局。

 本发明的实施方式
下面结合附图及实施例对本发明作进一步描述：
实施例一：参见图1至图6所示，一种具有电池盒结构的电动自行车车架管，包括具有中空管状结构的车架管本体1，在所述车架管本体上部开设有开口2，与所述开口2配合设置有电池盒体3；所述车架管本体为单管结构，在管体的两个侧壁上分布有肋板4，两个侧壁上的肋板4边缘之间的距离自上向下缩减；肋板边缘之间的空腔构成电池盒容纳位5；所述电池盒体3的侧壁形状与所述电池盒容纳位5的形状配合。
如图2所示，在每一侧壁上设有间隔布置的7个肋板4，各肋板均包括沿车架管长度方向延展的水平板，上方的肋板的宽度小于下方的肋板，位于最下方的一对肋板具有从水平板边缘向侧下方延展构成的侧板6，在车架管的横剖面上，自上向下各肋板的边缘的连线构成直线，侧板的延展方向与该连线的方向一致，参见图5所示，两侧板间的上述各连线之间构成上宽下窄的电池盒容纳位，电池盒体的侧壁形成与该电池盒容纳位的形状配合，从而，在电池合体装入后，各肋板对电池盒体起到支撑作用。
本实施例中，所述电池盒体与所述车架管本体上的电池盒容纳位一端构成旋转连接配合，与另一端的车架管本体之间设有锁定结构；所述电池盒体与车架管本体的锁定结构一端之间设有弹片结构，在锁定结构解锁时，所述弹片结构将电池盒体一端弹出。
