需要说明的是，当组件被称为“固定于”另一个组件，它可以直接在另一个组件上或者也可以存在居中的组件。当一个组件被认为是“连接”另一个组件，它可以是直接连接到另一个组件或者可能同时存在居中组件。当一个组件被认为是“设置于”另一个组件，它可以是直接设置在另一个组件上或者可能同时存在居中组件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1，本发明的一实施方式的车轮结构100，其应用于赛车、格斗车量等遥控移动装置（图未示出）中。具体地，所述遥控移动装置包括车体以及设置于所述车体上的所述车轮结构100，通过驱动所述车轮结构100转动，可以带动所述车体移动，并完成相应的竞技动作。
所述车轮结构100包括安装机构10、设置于所述安装机构10上的驱动组件30以及连接于所述驱动组件30上的车轮组件50。
请同时参阅图2及图3，所述安装机构10包括安装座12以及设置于所述安装座12上的盖体14。所述安装座12用于装设所述驱动组件30，所述盖体14用于收容所述驱动组件30的部分结构。
所述安装座12包括第一安装件121及第二安装件123，所述第一安装件121及所述第二安装件123均大致呈板状，其相互组合呈“L”形固定连接于一起。所述第一安装件121的一侧设置有固定部1211，所述固定部1211用于固定所述驱动组件30的部分结构。所述第二安装件123设置于所述第一安装件121上设置有所述固定部1211的一侧，并位于所述第一安装件121的边缘处。所述第二安装件123大致垂直于所述第一安装件121设置。
所述盖体14装设在所述第一安装件121上设置有所述固定部1211的一侧，并盖设于所述第一安装件121及所述第二安装件123上。所述盖体14与所述第一安装件121及所述第二安装件123共同围成一收容空间，所述收容空间用于收容所述驱动组件30的部分结构。
请同时参阅图4，在本实施方式中，所述驱动组件30为无刷电机及用于驱动所述无刷电机的电子调速器。具体地，所述驱动组件30包括基座32、固定地设置于基座32上的定子34、可转动地连接于所述基座32上的转子36、设置于所述转子36上的转轴组件38以及设置于所述安装机构10内的电子调速器39。
所述基座32固定地设置在所述第一安装件121背离所述盖体14的一侧。
所述定子34设置于所述基座32上，所述定子34上绕设有线圈（图未示出）。
所述转子36罩设于所述定子34外周，其包括所述磁轭361及设置于所述磁轭361上的所述磁体363。
所述磁轭361大致呈具有底壁的圆柱筒状，其可转动地罩设于所述定子34的外周。所述磁轭361包括周壁3611及设置于所述周壁3611一端的底壁3613。所述周壁3611大致呈圆柱筒状，其用于装设所述磁体363。所述底壁3613盖设于所述周壁3611远离所述基座32的一端。
所述磁体363的数量为多个，多个所述磁体363固定地设置于所述磁轭361的所述周壁3611的内侧，并沿所述周壁3611的周向间隔排列设置。每个所述磁体363对应于一个所述线圈（图未示出）。
所述转轴组件38包括转轴381、设置于所述转轴381上的安装件383以及设置于所述安装件383上的磁性件385。
所述转轴381大致呈圆柱杆状，其一端固定地插设于所述底壁3613上，另一端可转动地穿过所述基座32及所述第一安装件121，并收容于所述收容空间中。当所述无刷电机通电作业时，所述转子36带动所述转轴组件38相对所述定子34、所述基座32及所述安装机构10转动。
所述安装件383固定地设置于所述转轴381收容于所述收容空间的一端，所述磁性件385设置于所述安装件383上。所述电子调速器39设有用于与所述磁性件385相配合的传感器，以感测所述转子36的转动角度及转动速度。
所述电子调速器39设置在所述第一安装件121的所述固定部1211上，并邻近所述磁性件385设置。电子调速器39用于控制转子36的转动速度及转动方向。
所述车轮组件50设置在所述转子36远离所述安装机构10的一端，并与所述磁轭361固定连接，且能够在所述转子36的驱动下转动。
所述车轮组件50包括保持架52以及设置于所述保持架52上的滚动体56。
在本实施方式中，所述保持架52的数量为两个。两个所述保持架52大致平行相对地固定连接于一起。每个所述保持架52均包括轮毂部521以及设置于所述轮毂部521上的保持部523。
所述轮毂部521大致呈具有开口的圆盆状，两个所述保持架52的所述轮毂部521的开口相对地扣合于一起，并相互固接。两个所述轮毂部521中的一个固定地连接在所述底壁3613上。
所述保持部523大致呈波浪形的环状，其形成于所述轮毂部521的外周。两个所述保持架52的所述保持部523的最外端彼此相间隔设置。具体地，两个所述保持部523远离对应的所述轮毂部521的一端彼此相间隔，两个所述保持部523用于共同装设所述滚动体56。
在本实施方式中，所述滚动体56的数量为多个，多个所述滚动体56设置在两个所述保持部523之间，并能够相对所述保持架52转动。每个所述滚动体56大致呈圆柱状，其通过一连接轴（图标出）可转动地连接在所述保持架52上。具体地，每个所述滚动体56的两端分别与两个所述保持架52的保持部523相连接，多个所述滚动体56沿所述保持架52的周向排列设置。所述滚动体56的轴线与所述保持架52的轴线不相平行。在本实施方式中，所述滚动体56的轴线与所述保持架52的轴线相异面设置。
进一步地，所述滚动体56的外径自两端向中间中部位置逐渐变大，使所述滚动体56的外周壁大致呈略微外凸的曲面。
当所述车轮组件50在地面上滚动时，多个所述滚动体56的外周壁依次与地面相接触，由于所述滚动体56的轴线与所述保持架52的轴线相异面设置，使得所述滚动体56在所述保持架52的外周呈倾斜状布置，增加了所述车轮组件50的抓地力，有利于所述车轮结构100在地面上高速行进或急停。
进一步地，所述滚动体56的外周壁大致呈略微外凸的曲面，适当地减小了所述车轮结构100与地面的接触面积，使所述车轮结构100能够在高速输入时进行更快的反应，保持高速行进的状态，并尽可能地减小了摩擦，减小了输出功耗。且由于所述滚动体56为可转动地设置在所述保持架52上，其外周壁可以依次、均匀地与地面接触并承受磨损，整体上使得所述车轮结构100在一定时间内的磨损量减小，延长了所述车轮结构100的使用寿命。
组装本实施方式的车轮结构100时，首先，将将所述线圈（图未示出）绕设于所述定子34上，将所述定子34装设于所述基座32上。然后，将所述磁体363装设于所述磁轭361上，再将所述转轴组件38的转轴381的一端插设于所述转子36的所述底壁3613上。最后，将所述转轴组件38的转轴381的另一端穿过所述定子34、所述基座32及所述第一安装件121，再将所述电子调速器39邻近所述磁性件385装设于所述固定部1211上，并将所述盖体14盖设于所述第一安装件121与第二安装件123上。
上述遥控移动装置的车轮结构100，通过所述无刷电机直接驱动所述车轮组件50转动，利用了无刷电机低损耗、低噪音、运转顺畅及寿命长的优势，使所述遥控移动装置运行时噪声相对较小，且损耗较低。由于所述无刷电机可以直接通过所述电子调速器39控制转速及方向，在低转速的同时能够输出较大扭矩，不需要额外设置减速机构，进一步降低了所述遥控移动装置的运行噪声，并使所述遥控移动装置的结构更为精简，易于组装，且降低了生产成本。
可以理解，所述保持架52的结构可以不局限于上文所述的结构，其可以设计为其他结构，例如，所述保持架52可以包括一轮毂以及设置于所述轮毂外的保持件，所述轮毂固定地连接在所述转子36上，所述保持件设置在所述轮毂上并用于装设所述滚动体56。
以上实施方式仅用以说明本发明的技术方案而非限制，尽管参照以上较佳实施方式对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或等同替换都不应脱离本发明技术方案的精神和范围。
