如图1所示，本发明提供了一种方向盘100，该方向盘100包括方向盘轮缘110和方向盘中心部120，并且，方向盘轮缘110能够相对于方向盘中心部120运动，需要说明的是，方向盘轮缘110相对于方向盘中心部120的运动包括，方向盘轮缘110能够相对于方向盘中心部120在图1的箭头所指方向上转动，以及，方向盘轮缘110能够相对于方向盘中心部120在方向盘中心部120的纵向平移。此外，方向盘轮缘110安装为能够围绕第一旋转轴线A1旋转，使得驾驶员控制车辆的行驶方向。
以下参照图2继续描述根据本发明第一实施例的方向盘。
如图2所示，方向盘轮缘110包括与其一体成型的两个幅条1103，这两个幅条1103以相隔180度的方式设置在同一条直线上，并且，该幅条1103位于方向盘轮缘110和方向盘中心部120之间以用于连接方向盘轮缘110和方向盘中心部120。此外，方向盘轮缘110包括第一突伸部1101和 第二突伸部1102，该第一突伸部1101和第二突伸部1102分别能够在方向盘中心部120的第一轨道和第二轨道中移动，这将在下文进行详细描述。而且具体地，在本实施例中，第一突伸部1101和第二突伸部1102设置在连接方向盘轮缘110和方向盘中心部120的幅条1103上，并且这两个突伸部位于幅条110面向方向盘中心部120的端面上。本领域技术人员能够理解，尽管在以上实施例中，将方向盘轮缘描述为设置有与其一体成型的两个幅条，并且将两个突伸部设置在该幅条上，但是这仅仅是示例，本发明的方向盘不限于此，可以根据实际情况(例如，考虑到用户对空间利用的个性化需求)进行不同的设置，例如，可以仅设置一个幅条，又例如，可以将突伸部设置在幅条的除面向方向盘中心部的端面之外的其他位置处，甚至直接设置在方向盘轮缘上。
以下参照图3继续描述根据本发明第一实施例的方向盘。
如图3所示，方向盘中心部120上设置有第一轨道1201和第二轨道1202，正如上文提到的，方向盘轮缘110的第一突伸部1101和第二突伸部1102分别能够在方向盘中心部120的第一轨道1201和第二轨道中1202移动。具体地，第一轨道1201和第二轨道1202均仅在方向盘中心部120上延伸、未延伸到转向柱壳体130，在第一轨道1201和第二轨道1202中，第二轨道1202被设置为直线型轨道，该第二轨道1202的延伸方向平行于第一旋转轴线A1。并且，第一轨道1201被设置为具有在右端处的直线型轨道部段和左端处的变化部段1201A。在本实施例中，变化部段1201A被设置为圆弧形，并且，该圆弧以第二轨道1202的左端点为圆心，因此，第一轨道1201的延伸方向在该变化部段1201A处发生变化，与此同时，第一轨道1201和第二轨道1202之间的距离在变化部段1201A处也发生变化，具体地，两者之间的距离在变化部段1201A处减小。
因此，当方向盘轮缘110的第一突伸部1101在方向盘中心部120的第一轨道1201的变化部段1201A处移动时，第一突伸部1101的移动轨迹(与变化部段1201A重合)为以第二轨道1202的左端点为圆心的一段圆弧。与此相应地，方向盘轮缘110围绕第二旋转轴线进行转动，该第二旋转轴线垂直于第一旋转轴线A1并且经过第二轨道1202的左端点。在这种 情况下，第一突伸部1101沿着第一轨道1201移动时，在第一轨道1201的变化部段1201A处，第一突伸部1101沿着第一轨道1201的移动转变为方向盘轮缘围绕第二旋转轴线的转动，并且，第二旋转轴线垂直于第一旋转轴线A1。
在需要对方向盘进行收纳的情形下，使第一突伸部1101从变化部段1201A的左端点移动到右端点，此时，方向盘轮缘110围绕第二旋转轴线进行转动，之后，第一突伸部1101和第二突伸部1102分别沿着第一轨道1201和第二轨道1202移动使得方向盘轮缘110在方向盘中心部120的纵向上移动，直到第一突伸部1101和第二突伸部1102分别沿着第一轨道1201和第二轨道1202移动到两个轨道各自的右端点，此时，方向盘轮缘110进入收纳状态，如图4所示。由此，方向盘轮缘110由图1所示的第一状态进入由图4所示的第二状态，其中，在第一状态下，驾驶员通过操作方向盘轮缘110使其围绕第一旋转轴线A1转动而实现对车辆行驶方向的控制，在第二状态下，方向盘轮缘110处于收纳状态并且不用于控制车辆的行驶方向，此时不需要驾驶员时刻参与车辆的驾驶，由此驾驶员可以将其注意力转移到其感兴趣的事项或者进行休息，在这种情况下方向盘轮缘被收纳能够为驾驶员提供更大的空间和更高的舒适度。
需要说明的是，在本发明的方向盘中，方向盘轮缘110不限于能够相对于方向盘中心部120在图1的箭头所指方向上转动，例如，可以将该实施例中的第一轨道和第二轨道互换以使得方向盘轮缘能够相对于方向盘中心部在图1的箭头所指方向的反向上转动；以及，本发明的方向盘不限于以上实施例中具体描述的第一轨道1201和第二轨道1202，第一轨道和第二轨道之间的距离不限于在变化部段处发生变化，例如，可以将上述实施例中的第二轨道1202的左端的一段设置为圆弧，并且该圆弧和第一轨道1201的变化部段1201A布置为同心的两段圆弧；又例如，以上实施例中的变化部段可以设置在第一轨道的右端。
因此，在本发明的方向盘中，通过在方向盘中心部上设置变化部段，第一轨道和第二轨道中的至少一者的延伸方向在变化部段处发生变化，使得在变化部段处，仅第一突伸部沿着第一轨道的移动、或仅第二突伸部沿 着第二轨道的移动、或第一突伸部沿着第一轨道的移动且第二突伸部沿着第二轨道的移动转变为方向盘轮缘的转动，使得方向盘轮缘被收纳。因此，在本发明的方向盘中，仅需要通过驱动两个突伸部分别沿着两个轨道移动，即可实现方向盘轮缘的转动，并且，通过设置轨道的延伸方向可以控制方向盘轮缘相对于方向盘中心部的位置，换言之，控制方向盘轮缘的收纳程度，方便为用户提供个性化的设计。因此，本发明提供了一种能够以简单的结构和低廉的成本实现被收纳的方向盘。
以下描述本发明方向盘的其他实施例。
图5-图7示意性地示出根据本发明第二实施例的方向盘。以下参照图5-图7描述根据本发明第二实施例的方向盘。需要说明的是，以下主要针对第二实施例与第一实施例之间的不同之处进行描述，相同之处不再描述以避免冗余。
如图5所示，方向盘轮缘110’包括缺失部110’A，并且，该缺失部110’A在方向盘轮缘110围绕第二旋转轴线旋转时抵靠转向柱壳体130(如图7所示)。
如图6所示，方向盘中心部120’上设置有第一轨道1201’和第二轨道1202，具体地，在第一轨道1201’和第二轨道1202中，第二轨道1202被设置为直线型轨道，并且，第一轨道1201’被设置为具有在左端处和右端处的两个变化部段1201’A、1201’B以及位于两个变化部段之间的直线型轨道部段。在本实施例中，两个变化部段1201’A、1201’B被设置为圆弧形，并且，这两段圆弧分别以第二轨道的左端点和右端点为圆心，因此，第一轨道1201’的延伸方向在两个变化部段1201’A、1201’B处发生变化，并且，第一轨道1201’和第二轨道1202之间的距离在变化部段1201’A、1201’B处也发生变化，具体地，两者之间的距离在变化部段1201’A处减小，而在变化部段1201’B处，第一轨道1201’的端点与第二轨道1202位于同一条直线但是与第二轨道1202的右端点间隔开一段距离。需要说明的是，本文中提到的第一轨道和第二轨道之间的距离在变化部段处发生变化可以理解为，设置于一个轨道上的变化部段中的不同两个点相对于另一个轨道的距离不同，使得两个轨道在变化部段处表现为以彼此靠近或彼此 远离的方式延伸。因此，在本实施例中，在变化部段1201’B处，第一轨道1201’与第二轨道1202可以理解为彼此之间的距离减小，使得两个轨道在该变化部段处表现为以彼此靠近的方式向图1中的右侧方向延伸。
因此，当方向盘轮缘110’的第一突伸部1101在方向盘中心部120’的第一轨道1201’的变化部段1201’A处移动时，第一突伸部1101的移动轨迹为以第二轨道1202的左端点为圆心的一段圆弧。与此相应地，方向盘轮缘110’围绕第二旋转轴线进行第一次转动，该第二旋转轴线垂直于第一旋转轴线A1并且经过第二轨道1202的左端点。当方向盘轮缘110’的第一突伸部1101在方向盘中心部120’的第一轨道1201’的变化部段1201’B处移动时，第一突伸部1101的移动轨迹为以第二轨道1202的右端点为圆心的一段圆弧。与此相应地，方向盘轮缘110’围绕第二旋转轴线进行第二次转动，该第二旋转轴线垂直于第一旋转轴线A1并且经过第二轨道的右端点。在这种情况下，第一突伸部1101沿着第一轨道1201’移动时，在第一轨道1201’的变化部段1201’A和1201’B处，第一突伸部1101’沿着第一轨道1201’的移动转变为方向盘轮缘110’围绕不同的两个第二旋转轴线的两次转动，并且，不同的两个第二旋转轴线均垂直于第一旋转轴线A1。
在需要对方向盘进行收纳的情形下，使第一突伸部1101从变化部段1201’A的左端点移动到右端点，此时方向盘轮缘110’围绕第二旋转轴线进行第一次转动，之后，第一突伸部1101和第二突伸部1102分别沿着第一轨道1201’和第二轨道1202移动使得方向盘轮缘110’在方向盘中心部120的纵向上移动，之后，第一突伸部1101从变化部段1201’B的左端点移动到右端点时，方向盘轮缘110’围绕第二旋转轴线进行第二次转动，第二次转动完成之后方向盘轮缘110’进入收纳状态，如图7所示。由此，方向盘轮缘110’由类似于图1所示的第一状态进入由图7所示的第二状态。与第一实施例相比，由于第一轨道1201’的右端点与第二轨道1202设置在同一条直线上，因此，收纳后的方向盘轮缘110’相对于方向盘中心部120’在图1的箭头方向上进一步转动，使得收纳后的方向盘轮缘占用的空间更小。
图8-图9示意性地示出根据本发明第三实施例的方向盘。以下参照图8-图9描述根据本发明第三实施例的方向盘。需要说明的是，以下主要针 对第三实施例与第二实施例之间的不同之处进行描述，相同之处不再描述以避免冗余。
如图8所示，方向盘轮缘110”包括缺失部110”A、110”B，并且，该缺失部110”A、110”B在方向盘轮缘110”围绕第二旋转轴线旋转时分别抵靠转向柱壳体130和方向盘中心部120”(如图9所示)。具体地，两个辐条1103确定的直线和缺失部110”A、110”B确定的直线垂直。
能够理解，在第二实施例中，第一突伸部1101从变化部段1201’B的左端点移动到右端点时，方向盘轮缘110’围绕第二旋转轴线进行第二次转动，使得方向盘轮缘110进入收纳状态，作为对比，在第三实施例中，两个突伸部可以分别沿着两个轨道进一步移动，以使方向盘轮缘110”的左端不超出方向盘中心部120”的左端面。由此，方向盘轮缘110”由类似于图1所示的第一状态进入由图9所示的第二状态。与第二实施例相比，由于方向盘轮缘110”的左端不超出方向盘中心部120”的左端面，因此，使得收纳后的方向盘轮缘占用的空间更小。
图10示意性地示出根据本发明第四实施例的方向盘。以下参照图10描述根据本发明第四实施例的方向盘。需要说明的是，以下主要针对四实施例与第一实施例之间的不同之处进行描述，相同之处不再描述以避免冗余。
如图10所示，不同于第一实施例，本实施例中的第一轨道和第二轨道两者均从方向盘中心部120开始延伸、直到延伸至与方向盘中心部120的轴向一端(图10中的右端)连接的转向柱壳体130上。在这种情形下，车辆可以在自动驾驶模式下行驶，通过线控转向系统、而非方向盘控制车辆的行驶方向。而且，在方向盘进行收纳的同时，转向柱壳体130可以被收缩。
作为本发明的可选实施例，方向盘中心部120的轴线、转向柱壳体130的轴线可以设置为均与第一旋转轴线A1重合。
需要说明的是，尽管以上实施例均以一段圆弧形式的变化部段进行描述，但是本发明的方向盘不限于此，本领域技术人员可以根据实际情况将变化部段设计为其他形式，例如，多段圆弧组成的变化部段或者其他曲线 形状。
如前所述，尽管说明中已经参考附图对本发明的示例性实施例进行了说明，但是本发明不限于上述具体实施方式，本发明的保护范围应当由权利要求书及其等同含义来限定。
