如图5所示，第一滑动端511和第二滑动端521为圆柱状，第一滑动端511的外周面和第二滑动端521的外周面分别与凹槽状的第一凸轮轨道501和凹槽状的第二凸轮轨道502的内壁滑动配合。
参考图3、4，驱动组件5还包括模式风门连杆54。模式风门连杆54具有第四滑动端541、第四连杆轴线54a和第四驱动端542；模式风门连杆54被设置成围绕第四连杆轴线54a转动；第二驱动端522具有第二连杆轨道52b；第四滑动端541被设置成沿第二连杆轨道52b滑动；第四滑动端541与第二连杆轴线52a之间的距离为第四距离D4；第二凸轮连杆52通过第四距离D4的变化而致动模式风门连杆54；第四驱动端542用于驱动模式风门4。第二连杆轨道52b由设置在第二驱动端522的长条形孔的内壁限定。该长条形孔优选为通孔。第二连杆轨道52b通过与第四滑动端541的配合实现动力的传动过程，使得模式风门连杆54在第二凸轮连杆52的驱动下具有较大的转动范围。第四连杆轴线54a优选为平行于第二连杆轴线52a，且与第二连杆轴线52a保持相对静止。
如图5、6、7所示，第一凸轮轨道501具有至少一个第一空闲段501a和至少一个第一驱动段501b，其中，第一距离D1在第一空闲段501a内不变，且在第一驱动段501b内变化；第二凸轮轨道502具有至少一个第二空闲段502a和至少一个第二驱动段502b，其中，第二距离D2在第二空闲段502a内不变，且在第二驱动段502b内变化。
第一空闲段501a在以凸轮轴线50a为中心的圆上延伸，使得第一距离D1可以保持不变。第一驱动段501b从以凸轮轴线50a为中心的一个圆延伸至以凸轮轴线50a为中心的另一个圆上，使得第一距离D1能够变化。
第二空闲段502a在以凸轮轴线50a为中心的圆上延伸，使得第二距离D2可以保持不变。第二驱动段502b从以凸轮轴线50a为中心的一个圆延伸至以凸轮轴线50a为中心的另一个圆上，使得第二距离D2能够变化。
由于第一空闲段501a、第一驱动段501b、第二空闲段502a和第二驱动段502b的存在，空气混合风门3和模式风门4可以被驱动至不同的开度，从而形成图6、7、8、9、10、11、12、13、 14所示的多种不同的空调模式M1、M2、M3、M4、M5、M6、M7。不同的空调模式通过不同的驱动模式来进行切换。
参考图7，凸轮50的转动路径包括角度位置A1、A2、A3、A4、A5、A6、A7、A8、A9、A10、A11、A12、A13、A14。凸轮50可以在角度位置A1和角度位置A14之间往复运动。凸轮50可以被设置成从第一角度位置A1转动340°至第十四角度位置A14。
结合图6、7、8，在第一空调模式M1中，凸轮50从第一角度位置A1转动至第二角度位置A2，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-1滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-1滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3在最大开度W1保持不变，使得空气全部通过空气处理单元2；吹脚风门4-1在第一最小开度X1保持不变，吹面风门4-2在最小开度Y1保持不变，除霜风门4-3在最大开度Z1保持不变，因此，第一空调模式M1为除霜模式。
结合图6、7，在第一驱动模式S1中，凸轮50从第二角度位置A2转动至第三角度位置A3，第一滑动端511沿第一凸轮轨道501的第一驱动段501b-1滑动，第一距离D1发生变化，使得第一凸轮连杆51被凸轮50致动，从而使得空气混合风门3的开度发生变化；并且至少一部分第二滑动端521沿第二凸轮轨道502的第二驱动段502b-1滑动，至少一部分第二距离D2发生变化，使得至少一部分第二凸轮连杆52被凸轮50致动，从而使得至少一部分模式风门4的开度发生变化；其中，空气混合风门3从第一最大开度W1减小至第一中间开度W2，吹脚风门4-1从第一最小开度X1增加至第一中间开度X2，吹面风门4-2在最小开度Y1保持不变，除霜风门4-3从最大开度Z1减小至第一中间开度Z2。
结合图6、7、9，在第二空调模式M2中，凸轮50从第三角度位置A3转动至第四角度位置A4，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-2滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-2滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3在第一中间开度W2保持不变，使得空气一部分通过空气处理单元2，另一部分绕过空气处理单元2；吹脚风门4-1在第一中间开度X2保持不变，吹面风门4-2在最小开度Y1保持不变，除霜风门4-3在第一中间开度Z2保持不变，因此，第一空调模式M2为吹脚除霜模式。
结合图6、7，在第二驱动模式S2中，凸轮50从第四角度位置A4转动至第五角度位置A5，第一滑动端511沿第一凸轮轨道501的第一驱动段501b-2滑动，第一距离D1发生变化，使得第一凸轮连杆51被凸轮50致动，从而使得空气混合风门3的开度发生变化；并且至少一部分第二滑动端521沿第二凸轮轨道502的第二驱动段502b-2滑动，至少一部分第二距离D2发生变化，使得至少一部分第二凸轮连杆52被凸轮50致动，从而使得至少一部分模式风门4的开度发生变化；其中，空气混合风门3从第一中间开度W2增加至第二最大开度W3，吹脚风门4-1从第一中间开度X2增加至最大开度X3，吹面风门4-2在最小开度Y1保持不变，除霜风门4-3从第一中间开度Z2减小至第二中间开度Z3。
结合图6、7、10，在第三空调模式M3中，凸轮50从第五角度位置A5转动至第六角度位置A6，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-3滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-3滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3在第二最大开度W3保持不变，使得空气全部通过空气处理单元2，在这个实施例中，第二最大开度W3等于第一最大开度W1；吹脚风门4-1在最大开度X3保持不变，吹面风门4-2在最小开度Y1保持不变，除霜风门4-3在第二中间开度Z3保持不变，因此，第三空调模式M3为吹脚模式。
结合图6、7，在第三驱动模式S3中，凸轮50从第六角度位置A6转动至第七角度位置A7，第一滑动端511沿第一凸轮轨道501的第一驱动段501b-3滑动，第一距离D1发生变化，使得第一凸轮连杆51被凸轮50致动，从而使得空气混合风门3的开度发生变化；并且第二滑动端521沿第二凸轮轨道502的第二驱动段502b-3滑动，第二距离D2发生变化，使得第二凸轮连杆52被凸轮50致动，从而使得模式风门4的开度发生变化；其中，空气混合风门3从第二最大开度W3减小至第二中间开度W4，吹脚风门4-1从最大开度X3减小至第二中间开度X4，吹面风门4-2从最小开度Y1增加至中间开度Y2，除霜风门4-3从第二中间开度Z3减小至最小开度Z4。
结合图6、7、11，在第四空调模式M4中，凸轮50从第七角度位置A7转动至第八角度位置A8，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-4滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-4滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3在第二中间开度W4保持不变，使得空气一部分通过空气处理单元2，另一部分绕过空气处理单元2， 在这个实施例中，第二中间开度W4等于第一中间开度W2；吹脚风门4-1在第二中间开度X4保持不变，在这个实施例中，第二中间开度X4等于第一中间开度X2；吹面风门4-2在中间开度Y2保持不变，除霜风门4-3在最小开度Z4保持不变，因此，第四空调模式M4为吹面吹脚模式。
结合图6、7，在第四驱动模式S4中，凸轮50从第八角度位置A8转动至第九角度位置A9，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-4滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且至少一部分第二滑动端521沿第二凸轮轨道502的第二驱动段502b-4滑动，至少一部分第二距离D2发生变化，使得至少一部分第二凸轮连杆52被凸轮50致动，从而使得至少一部分模式风门4的开度发生变化；其中，空气混合风门3在第二中间开度W4保持不变，吹脚风门4-1从第二中间开度X4减小至最小开度X5，吹面风门4-2从中间开度Y2增加至最大开度Y3，除霜风门4-3在最小开度Z4保持不变。
结合图6、7、12，在第五空调模式M5中，凸轮50从第九角度位置A9转动至第十角度位置A10，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-4滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-5滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3在第二中间开度W4保持不变，使得空气一部分通过空气处理单元2，另一部分绕过空气处理单元2，在这个实施例中，第二中间开度W4等于第一中间开度W2；吹脚风门4-1在最小开度X5保持不变；吹面风门4-2在最大开度Y3保持不变，除霜风门4-3在最小开度Z4保持不变，因此，第五空调模式M5为第一吹面模式，在这一模式中，由于空气混合风门3的开度相对较大，通过空气处理单元2的空气的量相对较多，所以吹面的温度相对较高。
结合图6、7，在第五驱动模式S5中，凸轮50从第十角度位置A10转动至第十一角度位置A11，第一滑动端511沿第一凸轮轨道501的第一驱动段501b-4滑动，第一距离D1发生变化，使得第一凸轮连杆51被凸轮50致动，从而使得空气混合风门3的开度发生变化；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-5滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3从第二中间开度W4减小至第三中间开度W5，吹脚风门4-1在最小开度X5保持不变，吹面风门4-2在最大开度Y3保持不变，除霜风门4-3在最小开度Z4保持不变。
结合图6、7、13，在第六空调模式M6中，凸轮50从第十一角度位置A11转动至第十二角度位置A12，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-5滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-5滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3在第三中间开度W5保持不变，使得空气一部分通过空气处理单元2，另一部分绕过空气处理单元2；吹脚风门4-1在最小开度X5保持不变；吹面风门4-2在最大开度Y3保持不变，除霜风门4-3在最小开度Z4保持不变，因此，第六空调模式M6为第二吹面模式，在这一模式中，由于空气混合风门3的开度相对较小，通过空气处理单元2的空气的量相对较少，所以吹面的温度相对较低。
结合图6、7，在第六驱动模式S6中，凸轮50从第十二角度位置A12转动至第十三角度位置A13，第一滑动端511沿第一凸轮轨道501的第一驱动段501b-5滑动，第一距离D1发生变化，使得第一凸轮连杆51被凸轮50致动，从而使得空气混合风门3的开度发生变化；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-5滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3从第三中间开度W5减小至最小开度W6，吹脚风门4-1在最小开度X5保持不变，吹面风门4-2在最大开度Y3保持不变，除霜风门4-3在最小开度Z4保持不变。
结合图6、7、14，在第七空调模式M7中，凸轮50从第十三角度位置A13转动至第十四角度位置A14，第一滑动端511沿第一凸轮轨道501的第一空闲段501a-6滑动，第一距离D1保持不变，使得第一凸轮连杆51不会被凸轮50致动，从而使得空气混合风门3的开度保持不变；并且第二滑动端521沿第二凸轮轨道502的第二空闲段502a-5滑动，第二距离D2保持不变，使得第二凸轮连杆52不会被凸轮50致动，从而使得模式风门4的开度保持不变；其中，空气混合风门3在最小开度W6保持不变，使得空气全部绕过空气处理单元2；吹脚风门4-1在最小开度X5保持不变；吹面风门4-2在最大开度Y3保持不变，除霜风门4-3在最小开度Z4保持不变，因此，第七空调模式M7为第三吹面模式，在这一模式中，由于空气混合风门3的开度最小，通过空气处理单元2的空气的量相对最少，所以吹面的温度相对最低。
在本发明实施例的多种不同的空调模式M1、M2、M3、M4、M5、M6、M7中，第一滑动端511与第二滑动端521分别沿第一空闲段501a和第二空闲段502a滑动。在第一滑动端511从第一空闲段501a的起点滑动至终点的过程中，第二滑动端521从第二空闲段502a的起点同步地滑动 至终点。这样的设计使得空气处理装置90处于空调模式中时，空气混合风门3和模式风门4均不会被凸轮50的转动而驱动，从而使得空气处理装置90内的气流组织能够保持稳定，进而使得通过空气处理单元2调节出风温度的过程能够变得简单。
参考图6，第一空闲段501a的终点与第一驱动段501b的起点相连接；第二空闲段502a的终点与第二驱动段502b的起点相连接；和/或第一驱动段501b的终点与第一空闲段501a的起点相连接；第二驱动段502b的终点与第二空闲段502a的起点相连接。第一空闲段501a与第一驱动段501b相互间隔设置；第二空闲段502a与第二驱动段502b相互间隔设置。
参考图6、7，在第二滑动端521从第二空闲段502a的起点滑动至终点的过程中，例如沿图6中的第二空闲段502a-5滑动的过程中，第一滑动端511从第一空闲段501a-4的起点经由至少一个第一驱动段501b-4、501b-5同步地滑动至另一个具有不同的第一距离D1的第一空闲段502a-5、501a-6的终点。这样的设计使得空气混合风门3被驱动而模式风门4保持不动，使得在不改变出风口12的开闭状况的前提下，出风温度能够通过改变驱动而模式风门4的开度而被调节，进而使得通过空气处理单元2调节出风温度的过程能够变得简单。
继续参考图6，从一个第一空闲段501a-4滑动至另一个第一空闲段501a-6的过程中，第一距离D1单调地减小。在未图示的实施例中，第一距离D1也可以单调地增加。第一距离D1单调地变化使得空气混合风门3的开度可以单调地变化。
本发明虽然以较佳实施例公开如上，但其并不是用来限定本发明，任何本领域技术人员在不脱离本发明的精神和范围内，都可以做出可能的变动和修改，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何修改、等同变化及修饰，均落入本发明权利要求所界定的保护范围之内。
