技术领域
本发明涉及汽车领域，特别涉及一种可实现多方向振动的触摸开关、车窗触控开关及汽车。
背景技术
当前汽车内饰设计的趋势，触摸振动开关逐步代替传统的物理按钮。触摸的振动反馈可以给到用户最直观的操作感知，减少用户看着按键按压确认触摸是否成功的时间。随着汽车智能座舱的发展，用户对座舱内操控的便捷、安全和美观的要求也越来越高。目前振动开关的悬浮方式大多通过金属弹片连接，通过金属弹片自身的变形产生位移而引发振动。但是，在现有技术中，触摸振动开关基本仅局限于按压开关的法向(即金属弹片的法向)时有振动反馈，使得触摸振动开关的适用范围较窄。
车窗升降开关是控制汽车的车窗玻璃位置的必要装置，汽车玻璃升降开关在汽车中应用十分的普遍；通过拨动塑胶按钮的压下和弹起来控制车窗玻璃关闭或者开启。传统的车窗玻璃升降开关，开关按钮总会有一侧凸出于腔体的外表部，容易造成误触发。而且传统的车窗玻璃升降开关，不能进行按压行程的检测，因此按钮的行程靠机械配合来实现，进而使得按钮的行程较大，向下按压时按钮有一部分向下凹陷，向上抬起时按钮有一部分向上凸起，不但影响操作手感，而且在视觉上也不美观，同时还容易产生噪音。而能进行位移监测的车窗升降开关，往往结构件较多，而且装配复杂。
综上，现有技术中的触摸振动开关的适用范围较窄的缺陷；传统的车窗升降开关，存在着机械结构复杂，机械行程大，玻璃升降动作反应迟缓，容易造成误触发，操作手感较差，噪声大等缺点。

优选地，所述振动反馈模块还包括振动器，所述振动器为扬声器、线形谐振器、电磁线圈马达、偏心马达或者压电促进器中的任意一种。
一种汽车，其特点在于，其包括如上所述的车窗触控开关，其中，主驾位置采用设置有电容膜的车窗触控开关，副驾和后排采用不设置电容膜的车窗触控开关。
在本方案中，采用上述结构形式，在主驾位置的车窗升降开关同时设置电容膜和红外感应传感器，电容膜检测手指是否在位、红外感应传感器用于检测按钮支架产生位移变化量，当电容膜的检测值和红外感应传感器的检测值同时达到预设值之后，触摸开关被触发，控制模块会给振动模块发出振动指令，振动器作出振动反馈。采用这种设置，有利于驾驶员区分车窗的位置，进而防止驾驶员分散注意力以提高驾驶安全性。而在副驾和后排的车窗升降开关上设置无电容膜的开关，只通过红外感应传感器来检测按钮支架的位移变化，当位移变化达到预设值之后，触摸开关被触发，控制模块会给振动模块发出振动指令，振动器作出振动反馈。采用这种设置，以便于允许手、假肢等各种材质对开关的触发。
在符合本领域常识的基础上，上述各优选条件，可任意组合，即得本发明各较佳实例。
本发明的积极进步效果在于：在该实现多方向振动的触摸开关中，当力作用到按钮上的与电容片对应的至少两个表面中的一个时，按钮支架通过转轴相对于前盖转动，产生位移，使得中间弹性件发生形变，转轴起到支点的作用，使得作用到按钮上的力能够分解成金属弹片法线方向的作用力，金属弹片也会发生形变。当电容量变化和主电路板上的传感器感受到的位移变化量均达到预设值时，主电路板会发出信号，使得振动器模块振动，因此使得按钮支架和按钮振动，实现振动反馈。该触摸开关使得其受力面可以不仅仅局限于金属弹片的法线方向，提高了触摸开关的适用范围。本发明的车窗触控开关及包含其的汽车，通过红外感应传感器检测按钮支架的位移变化并反馈至控制模块，以使控制模块作出升窗或者降窗的动作指令以控制车窗玻璃的升降。由于红外感应传感器相对于机械接触反馈来说，具有精度高、感应灵敏、响应快的优点，还具有缩短按钮的按压行程以实现视觉上无行程、一体化的效果，并且可减小按钮的按压噪音，且使得车窗升降开关具有相应快的优点。而按钮支架与前盖可转动连接，以使得按钮支架和前盖形成一杠杆结构，使得升窗和降窗在一个开关上即可实现，进而简化开关的结构。按钮 的顶部低于盒体的顶面，使得在有物体不小心放置在盒体上面时，可避免物体触碰到按钮以触发车窗玻璃升降开关。

具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
实施例1
本实施例揭示一种可实现多方向振动的触摸开关，如图1-13所示，该触媒开关包括按钮10、按钮支架20、振动器模块30、金属弹片40、主电路板50和前盖60，按钮10和振动器模块30安装于按钮支架20，按钮10朝向按钮支架20的一侧设有至少两个位于不同表面的电容片70，至少两个电容片70与主电路板50上的至少两个插座80电连接。主电路板50和按钮支架20安装于前盖60，金属弹片40连接于前盖60和按钮支架20，按钮支架20通过一转轴可转动连接于前盖60，主电路板50上还设有用于感应位移变化量的传感器100。
在本实施方式中，在该实现多方向振动的触摸开关中，当力作用到按钮10上的与电容片70对应的至少两个表面中的一个时，按钮支架20通过转轴相对于前盖60转动，产生位移，使得中间弹性件90发生形变，转轴起到支点的作用，使得作用到按钮10上的力能够分解成金属弹片40法线方向的作用力，金属弹片40也会发生形变。当电容量变化和主电路板50上的传感器100感受到的位移变化量均达到预设值时，主电路板50会发出信号，使得振动器模块30振动，因此使得按钮支架20和按钮10振动，实现振动反馈。该触摸开关使得其受力面可以不仅仅局限于金属弹片40的法线方向，提高了触摸开 关的适用范围。
需要说明的，电容片70的数量与插座80的数量是一一对应的，当力作用到按钮10上时，通过电容片70与插座80的电连接，主电路板50能够读取到电容量的变化。在本实施例中，如图1和图3所示，电容片70的数量为两个。在其他可替代的实施方式中，可以设置三个或三个以上的电容片70。
如图1和图2所示，该触摸开关还包括后盖110，后盖110和前盖60相对设置并围成一容置腔体，主电路板50等相应元件位于上述容置腔体中。
如图1、图4-5所示，前盖60中朝向按钮支架20的一侧具有用于容置按钮支架20的第一容置腔601，按钮支架20的两外侧壁上设有第一转动部201，前盖60的两外侧壁上设有第二转动部602，第一转动部201和第二转动部602相适配以使按钮支架20相对于前盖60可转动。具体地，在本实施方式中，第一转动部201为转轴、第二转动部602为转动连接孔。
在其他可替代的实施方式中，也可将第一转动部201设置为转动连接孔、将第二转动部602设置为转轴。
其中，在第一转动部201和第二转动部602的作用下，按钮支架20相对于前盖60悬浮设计，当有力作用到按钮10上时，按钮支架20会相对于前盖60绕转轴转动，进而产生位移。
参照图12和13予以理解，第二转动部602靠近前盖60中远离按钮支架20的一侧，且第二转动部602靠近前盖60的底部。其中，采用上述设置，第二转动部602相当于位于前盖60的左下方，一方面，能够使按钮支架20具有较大的转动空间，以相对于前盖60自由转动；另一方面，作用力到转轴这一支点的距离较长，力臂较大，在所需力矩一定的情况下，有利于减少作用力。
参照图1、图4-10予以理解，触摸开关还包括中间弹性件90，按钮支架20中朝向前盖60的一侧设有凸出部202，中间弹性件90的一端套设于凸出部202，中间弹性件90的另一端用于作用于传感器100并压设于主电路板50。
其中，中间弹性件90装设在按钮支架20上，当按钮支架20转动以产生位移时，中间弹性件90会发生形变，传感器100能够感应到按钮支架20的位移变化量。
在本实施方式中，中间弹性件90为橡胶套，传感器100为红外传感器100，红外传感器100位于橡胶套的另一端的内部，凸出部202中朝向传感器100的一侧为反光面207(如图5、图12-13所示)。
其中，一方面，橡胶套有迫使发生形变的金属弹片40复位的缓冲作用，以吸收按压 带来的形变力量；另一方面，橡胶套有挡光的作用，以防止周围的光对红外传感器100的作用，有利于提高红外传感器100工作的可靠性，进而有利于提高触摸开关的可靠性。
具体地，在本实施方中，如图4-10所示，中间弹性件90和传感器100的数量为两个，两个中间弹性件90位于同一水平面，且两个中间弹性件90对称设置。如此设置，两个中间弹性件90和传感器100共同作用，有利于提高感应位移变化量的可靠性，进而有利于提高触摸开关的可靠性。
如图1、图4、图6-11所示，按钮支架20中朝向前盖60的一侧设有第一连接柱203，金属弹片40上设有与第一连接柱203相适配的第一连接孔401，金属弹片40通过第一连接柱203和第一连接孔401连接于按钮支架20；
前盖60中朝向按钮支架20的一侧设有第二连接柱603，第二连接柱603位于容置腔中，金属弹片40上设有与第二连接柱603相适配的第二连接孔402，金属弹片40通过第二连接柱603和第二连接孔402连接于前盖60。
另外，按钮支架20中朝向前盖60的一侧还设有用于容置第二连接柱603的容置孔204。容置孔204的设置有利于减少按钮支架20和前盖60占用的空间，进而有利于减少触摸开关整体占用的空间。
按钮支架20中朝向前盖60的一侧还设有定位柱206，金属弹片40上还设有用于与定位柱相适配的定位孔403。其中，定位柱206和定位孔403能够对金属弹片40进行预定位，有利于提高金属弹片40和按钮支架20连接的可靠性，进而也有利于提高金属弹片40和前盖60连接的可靠性。
另外，按钮支架20中朝向前盖60的一侧设有第二容置腔205，振动器模块30位于第二容置腔205内。采用上述设置，一方面，能够减少按钮支架20和振动器模块30占用的空间，进而能够减少触摸开关整体占用的空间；另一方面，有利于保护振动器模块30，进而有利于提高触摸开关整体的可靠性。
如图12所示，当F1的力分方向垂直作于按钮10的第一表面(上表面)时，会分解成力F11，根据杠杆原理，转轴处即为支点，在金属弹片40处产生力F12，力F12再分解成金属弹片40的法线方向的力F13，从而使得金属弹片40在法线方向上发生位移。
如图13所示，当F2的力分方向垂直作于按钮10的第二表面(上前表面)时，会分解成力F21，根据杠杆原理，转轴处即为支点，在金属弹片40处产生力F22，力F22再分解成金属弹片40的法线方向的力F23，从而使得金属弹片40在法线方向上发生位移。
本发明还提供一种包括上述可实现多方向振动的触摸开关。
本实施例中的触摸开关能够防止以下情形：如手指接触到了触摸按键，虽然有电容 量的变化但是没有发生位移，也不会引起触发功能的开启，即不能实现触摸振动；或者是汽车自振虽然也有位移量，但是没有电容的变化量，单条件下也不会实现开关的触摸振动反馈，一定需要电容量变化和主板上的红外传感器100感受到反光面位移的变化量两者条件都具备时，才能够实现开关的触摸振动反馈。
实施例2
如图14至图21所示，本实施例提供一种车窗触控开关，其包括盒体10和开关组件20，盒体10具有一顶部开口的容置腔，开关组件20置于容置腔内，开关组件20包括按钮支架201、按钮202、前盖203、红外感应传感器206和控制模块205，其中，按钮连接于按钮支架；前盖与按钮支架转动连接；红外感应传感器用于检测按钮支架的位移变化；控制模块与红外感应传感器电连接，控制模块用于接收红外感应传感器传输的位移变化信号；按钮位于盒体的开口处，按钮的顶部低于盒体的顶面。
其中，参照图14、图15和图19予以理解，通过红外感应传感器206检测按钮支架201的位移变化并反馈至控制模块205，以使控制模块205作出升窗或者降窗的动作指令以控制车窗玻璃的升降。由于红外感应传感器206相对于机械接触反馈来说，具有精度高、感应灵敏、响应快的优点，进而可缩短按钮202的按压行程以实现视觉上无行程、一体化的效果，并且可减小按钮202的按压噪音，且使得车窗升降开关具有响应快的优点。而按钮支架201与前盖203可转动连接，以使得按钮支架201和前盖203形成一杠杆结构，使得升窗和降窗在一个开关上即可实现，进而简化开关的结构。按钮202的顶部低于盒体的顶面，使得在有物体不小心放置在盒体10上面时，可避免物体触碰到按钮202以触发车窗玻璃升降开关。
而且，参照图15予以理解，本实施例提供的车窗触控开关还包括后盖208，后盖208和前盖203相对设置并围成一腔体，控制模块205等相应元件位于该腔体内。
在本实施例中，在前盖203中朝向按钮支架201的一侧设置有一容纳按钮支架201的凹槽。在前盖203的两个外侧壁上设置有转动连接孔2031，在按钮支架201上设置有转轴2014，前盖203上的转动连接孔2031与转轴2014可转动连接，使得按钮支架201能相对于前盖203转动。通过以上结构使得按钮支架201相对于前盖203悬浮设计，当有力作用到按钮202上时，按钮支架201会相对于前盖203绕转轴2014转动，进而产生位移。其中，将连接孔2031设置在前盖203中远离按钮支架201的一侧，且转轴2014靠近前盖203的底部。采用上述设置，一方面，能够使按钮支架201具有较大的转动空间，以相对于前盖203转动；另一方面，作用力到转轴2014这一支点的距离较长，力臂 较大，在所需力矩一定的情况下，有利于减少作用力。
在本实施例中，参照图14和图21予以理解，按钮包括第一按压部2021和第二按压部，第一按压部2021自盒体10的顶部向下倾斜，第二按压部2022的顶端与第一按压部2021的底端相连接，第二按压部2022的底端在竖直方向上向朝向第一按压部2021的方向倾斜。将第一按压部2021和第二按压部2022设置成向下倾斜的形式，可进一步防止对车窗开关误触发，进而提高车窗开关的可靠性。其中，第一按压部2021与盒体顶面之间的夹角在30°至45°为宜，优选的角度是30°；第二按压部2022与竖直方向的夹角在30°至45°为宜，优选的地角度是30°。
参照图14予以理解，容置腔包括安装部和避让部，安装部的顶部被盒体10的顶壁遮盖，避让部露出于开口，开关组件20安装于安装部内，按钮位于避让部，第一按压部2021的顶端与盒体顶壁101朝向避让部的一端的端部间隔设置。第一按压部2021的顶端与盒体顶壁101的端部间隔设置，以使得对按钮202进行操作时盒体10的顶部不会干涉按钮202的行程，以提高按钮202操作的舒适性。
参照图21予以理解，本车窗触控开关还包括弹片，弹片位于前盖和按钮支架之间。当按压力作用在按钮202的第一按压部2021上时，按钮支架201在按压力的作用下会沿转轴2014逆时针转动，从而对固接于其上的弹片204施加力，该力会使得弹片204一侧发生弹性变形。当力释放时，弹片回复正常状况。当按压力作用在按钮202的第二按压部2022上时，按钮支架201在按压力的作用下会沿转轴2014顺时针转动，从而对固接于其上的弹片204施加力，该力会使得弹片204一侧发生弹性变形。当力释放时，弹片回复正常。
由于按钮支架201下侧设置有红外感应传感器探测面2012，当按钮支架201转动时，其红外探测面2012相对于主板上红外感应传感器的位移会发生变化，当按压力作用在第一按压部2021时，相对位移是增大的，当按压力作用在第二按压部2022时，相对位移是减少的。本方案利用了红外感应传感器可以探测位移变化的这个特性，实现了利用一个传感器实现两个方向位移探测的目的。使得升窗和降窗的按压操作在一个按钮202上实现，简化了结构也节省了成本。
按钮支架201朝向前盖203的一侧设置有凸出部，前盖203的底板上与凸出部2011对应的位置开设有通孔，凸出部2011穿过通孔与控制模块205上的红外感应传感器206相对，凸出部2011上与红外感应传感器206相对的面为探测面2012。通过在按钮支架201上设置探测面2012，以实现红外感应传感器206对按钮支架201的位移变化的探测，进而缩短按钮202的按压行程以实现视觉上无行程、一体化的效果，并且可减小按钮202 的按压噪音。
凸出部2011的外部套设有橡胶套2013，探测面2012为镜面，按钮支架201朝向控制模块205的一侧的侧面除探测面2012外都做黑化处理。探测面2012的镜面，可通过提高探测面2012的光洁度实现探测面2012对光的反射效果，或者，也可以将探测面2012设置成白色的面以实现对光的反射。将按钮支架201的其他的面设置成黑色的，以使得其他的面可以吸收光线，不会反光，这样设置可提高红外感应传感器206的检测精度。橡胶套2013有迫使发生形变的弹片204复位的缓冲作用，以吸收按压带来的形变力量；另一方面，橡胶套2013有挡光的作用，以防止周围的光对红外感应传感器的作用，有利于提高红外感应传感器工作的可靠性，进而有利于提高触摸开关的可靠性。
其中，凸出部2011和红外感应传感器的数量为两个，两个凸出部2011对称设置。采用两个红外感应传感器206，有利于提高感应位移变化量的可靠性，进而有利于提高车窗升降开关的可靠性。
红外感应传感器的探测精度范围可以是2mm-0.01mm，优选0.1mm-0.02mm。在以下实施方案中，以红外感应传感器206的探测精度为0.02mm为例进行说明，按钮202的按压行程在0.1mm以内。采用上述结构形式，可实现按钮202在视觉上的无行程、一体化，同时可以实现按压行程0.1mm的有效探测。
如图18所示，弹片204包括连接部2042和两个变形部2041，两个变形部2041分别连接于连接部2042的长度方向的两端，变形部2041垂直于连接部2042的两端分别连接于按钮支架201和前盖203。变形部2041的形状为S形，两个变形部2041相对于连接部2042的中垂线对称设置。变形部2041的形状采用S形，一方面可增大变形部2041的弹性变形量，另一方面可减小变形部2041的应力，进而提高变形部2041的回弹性能。变形部2041相对于连接部2042的中垂线对称设置，使得变形部2041的变形均匀，进而提高弹片204的寿命。其中，在变形部2041上设置有通孔，变形部2041和按钮支架201及前盖203通过螺栓固定。
当按压按钮202时，由于按钮202卡接于按钮支架201，按压会带动按钮支架201沿转轴转动，前盖203和按钮支架201的相对位置发生变化时，弹片204会产生弹性变形，当按压力释放后，弹性形变恢复。弹片204的形变量和按压力存在一定的物理关系，这是由弹片204的结构构造和材料特性决定的。为了达到一定按压力下较小的按压行程，和力释放后恢复正常，需要弹性结构满足一定的刚度和弹性要求，在本实施例中，弹片204采用的是SUS304不锈钢，弹性模量在193Gpa，另外，弹片204也可采用其他的材料，例如：碳钢，铸铁，合金钢等。
在本实施例中，按压力3N的情况下，按压行程0.1mm，红外感应传感器探测区域位移量0.02mm，按压行程，弹片204形变量和探测区域位移量的传递关系是由系统结构设计实现的。红外感应传感器206的位移分辨率必须满足能够识别最小有效按压力带来的探测区域的位移变化量，同时为了识别有效按压，区分车辆在行驶过程中相对路面的振动带来的探测区域的位移变化和按压力带来的位移变化。系统以按压力最少0.1N/s的速度增加识别为有效按压，对应的接触力在2N～4.5N标定的位移变化为有效按压状态。
开关组件20还包括振动反馈模块，振动反馈模块连接于按钮支架201并抵靠于按钮202，振动反馈模块电连接于控制模块205。设置振动反馈模块，当系统探测量达到预设值时，控制模块205会发出信号，使得振动器模块产生一定的振幅、频率的振动，由于振动器模块固接于按钮支架201和按钮202，因此使得按钮支架201和按钮202振动，从而使人体手指感受到振动反馈。
按钮202朝向按钮支架201的一侧设置有电容膜207，电容膜207与控制模块205电连接。在按钮202上设置电容膜207，使得系统监测到的预设值可以是通过位移量，也可以是通过电容阀值来进行反馈。
振动反馈模块还包括振动器，振动器为扬声器、线形谐振器、电磁线圈马达、偏心马达或者压电促进器中的任意一种。当然，这种振动反馈模块也可以由光学反馈模块或者是声学反馈模块来替代，不限于利用振动这种方式发出反馈信号。
一种汽车，其包括如上的车窗触控开关，其中，主驾位置采用设置有电容膜207的车窗触控开关，副驾和后排采用不设置电容膜207的车窗触控开关。在主驾位置的车窗升降开关同时设置电容膜和红外感应传感器，电容膜检测手指是否在位、红外感应传感器用于检测按钮支架产生位移变化量，当电容膜的检测值和红外感应传感器的检测值同时达到预设值之后，触摸开关被触发，控制模块会给振动模块发出振动指令，振动器作出振动反馈。采用这种设置，有利于驾驶员区分车窗的位置，进而防止驾驶员分散注意力以提高驾驶安全性。而在副驾和后排的车窗升降开关上设置无电容膜的开关，只通过红外感应传感器来检测按钮支架的位移变化，当位移变化达到预设值之后，触摸开关被触发，控制模块会给振动模块发出振动指令，振动器作出振动反馈。采用这种设置，以便于允许手、假肢等各种材质对开关的触发。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这些仅是举例说明，在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改。因此，本发明的保护范围由所附权利要求书限定。
