请参考图1，本申请的实施例提供了一种触控反馈模组100，包括悬翼板110、传递结构120、触摸板130以及至少一个压电马达140，其中：
悬翼板110包括承载部111以及悬翼部112，悬翼部112围绕承载部111设置，并且悬翼部112连接于承载部111，具体设置时，承载部111可以为圆板，悬翼部112为环绕四周延伸设置的多条均匀设置支撑板，承载部111还可以为关于悬翼板110的中心线XY对称结构的长方体结构，在承载部111为圆板状结构或是长方体结构时，承载部111中的全部表面均能够用于承载其他部件，使得承载面积面积较大，能够用于集成较多的功能部件，使得触控反馈模组100的尺寸更为紧凑，当然悬翼板110的具体结构并不局限于上述圆板状结构或是长方体结构，还可以为其他具有较大承载面积的结构形式，如正方体结构；悬翼部112可以通过环氧树脂AB胶、UV胶等弹性胶连接于承载部111，当然连接方式并不局限于上述弹性胶，并且，如图2所示，承载部111和悬翼部112可以为一体式结构，悬翼部112凸出于承载部111的侧面沿垂直于悬翼板110的中心线XY的方向延伸；
传递结构120设置于悬翼部112，在具体设置时，传递结构120可以采用泡棉、橡胶、塑料等具有弹性的材料，硬度小于80A，以消除悬翼板 110变形带来的影响。传递结构120也可以采用刚性材料，然后在传递结构120与触摸板130之间设置环氧树脂AB胶、UV胶等弹性胶以实现连接，这样既可以保证传递结构120具有良好的传递效果，而且传递结构120与触摸板130之间的弹性胶具有一定的弹性可以消除悬翼板110变形带来的影响，传递结构120的形状可以呈长方体状，正方体状、圆柱状等，当然并不局限于此，还可以为其它形状；
至少一个压电马达140，每一压电马达140设置于承载部111，在具体设置时，压电马达140的数目可以为一个、两个、三个或是三个以上，压电马达140可以设置在承载部111朝向触摸板130的表面，也可以设置在承载部111背离触摸板130的表面，还可以一部分设置在承载部111朝向触摸板130的表面，另一部分设置在承载部111背离触摸板130的表面；压电马达140连接于悬翼板110的方式可以是机械式，例如卡扣连接、凹凸配合连接或者螺纹连接等，也可以是粘接，例如采用OCA光学胶、OCR光学胶、双面胶等；
触摸板130架设于传递结构120远离悬翼板110的一侧，在具体设置时，触摸板130可以通过环氧树脂AB胶、UV胶等弹性胶连接于传递结构120，当然连接方式并不局限于上述弹性胶，触摸板130与传递结构120以及悬翼板110形成容纳部121，该容纳部121为该触摸板130向下振动的空间，在压电马达140位于承载部111靠近触摸板130的一侧时，触摸板130与压电马达140之间具有一定的间距，该间距用于限制触摸板130的振动，并且大于触摸板130向下振动的振幅，以防止压伤压电马达140。
在上述触控反馈模组100中，触摸板130通过传递结构120架设于悬翼板110，悬翼部112围绕承载部111设置，并且悬翼部112连接于承载部111，承载部111上设置有压电马达140，悬翼部112上设置有传递结构120，以将压电马达140设置在传递结构120的内部空间内，使得在传递结构120围成的有限空间内集成较多的功能，进而提高触控反馈模组100的 小型化程度；按压触摸板130的外力通过传递结构120将力传递给悬翼部112，导致悬翼部112发生弯曲变形，进而带动压电马达140通过正压电效应产生电压输出，由于压电马达140设置在传递结构120的内部空间，以避免悬翼板110形变经过较长传递过程不易被压电马达140感知的情况发生，在按压触摸板130力度较小时，悬翼部112的较为微弱地变形能够压电马达140感知，以使得压力感知灵敏度较高，此时，压电马达140接收电压信号，通过逆压电效应产生力的作用，进而带动悬翼板110发生弯曲变形，从而通过传递结构120将振动传递给触摸板130，由于压电马达140设置在传递结构120的内部空间，使得触摸板130能够产生较小的沿层叠方向的位移，提高触控反馈的灵敏度。
在上述触控反馈模组100的基础上，为了进一步提高小型化程度，在一个或多个实施例中，如图3所示，在压电马达140的数目为多个时，多个压电马达140在承载部上环绕设置，并且排布成环状结构，此时环状结构的中心线与悬翼板110的中心线重合，承载部上对应于环状结构内部形成中空区域122，同样中空区域122的中心线与悬翼板110的中心线XY重合，压电马达140的数目可以为两个、三个、四个或四个以上；如图4所示，在压电马达140的数目为一个时，压电马达140为环状结构，该压电马达140的内部具有中空区域122，此时环状结构的中心线与悬翼板110的中心线XY重合。
上述触控反馈模组100中，通过将多个压电马达140排布成环状结构，或是在仅具有一个压电马达140时，选用环状结构的压电马达140，以在压电马达的内部形成中空区域122，从而为其它部件的设置提供位置，以便于在环状结构的中空区域122内集成功能部件，能够使得传递结构120围成的有限空间内集成更多的功能，进一步提高触控反馈模组100的小型化程度。
为了限制触摸板130相对于悬翼板110的振动幅度，具体地，如图5 以及图6，悬翼板110朝向触摸板130的一侧设有至少一个限位结构150，限位结构150与触摸板130间隔设置，在压电马达140设置在承载部111朝向触摸板130的一侧时，至少一个限位结构150设置在环状结构的中空区域122内，并且该限位结构150的高度高于压电马达140。
上述触控反馈模组100中，通过在悬翼板110朝向触摸板130的一侧设置有限位结构150，使得触摸板130的振动幅度受到限位结构150的限制。而限位结构150与触摸板130之间具有一定的间距，能够使得触摸板130在向下振动的过程中避免触碰限位结构150而产生机械损伤，也增加了触摸板130向下振动的幅度。将压电马达140设置在承载部111朝向触摸板130的一侧，以使得在触摸板130、传递结构120、悬翼板110围成的容纳部121内集成压电马达140，此时将限位结构150设置在中空区域122内，以在环状结构的中空区域122集成限位功能，并且限位结构150的高度高于压电马达140，避免触摸板130直接碰撞到压电马达140而产生机械损伤。
在实现相同的触摸板130的振幅，相对于将限位结构150设置在压电马达140背离承载部111的表面，上述触控反馈模组100中的限位结构150以及传递结构120在平行于悬翼板110中心线XY方向上的厚度较小，也即是通过较小的限位结构150就能够实现对触摸板130相对于悬翼板110的振动幅度的限位作用。而在具体设置时，限位结构150采用泡棉、橡胶、塑料等具有弹性的材料，硬度小于80A。如此设置，能够增加限位结构150的缓冲性能，避免触摸板130接触到限位结构150时发生机械损伤。例如，可以采用硬度为30A-50A的EVA多孔板(ethylene-vinyl acetate copolymer，乙烯-醋酸乙烯共聚物)，该EVA多孔板的长宽高尺寸为6mm*60mm*0.5mm。
值得注意的是，在压电马达140设置在承载部111朝向触摸板130的一侧时，至少一个限位结构150的设置方式并不局限于上述设置在环状结 构的中空区域122内的形式，该限位结构150还可以设置在压电马达140朝向触摸板130的表面上，此时压电马达140的数目和结构形式可以有多种形式，如压电马达140可以为环状结构，也可以为其他结构形式，多个压电马达140可以形成环状结构，也可以构成其他结构形式。
为了限位并支撑悬翼板110，如图7、图8、图9以及图10所示，具体地，承载部111背离触摸板130的一侧设有支撑结构，在压电马达140设置在承载部111朝向触摸板130的一侧时，支撑结构设置于环状结构的中空区域122内，值得注意的是，此时的触控反馈模组100中也可以设置上述限位结构150，并且该限位结构150的中心线与悬翼板110的中心线相重合。
上述触控反馈模组100中，在实现相同的悬翼板110的振幅，相对于压电马达140为中没有中空区域122、并将支撑结构设置在该没有中空区域122的压电马达140外侧的情况，上述触控反馈模组100中的支撑结构在平行于悬翼板110中心线XY方向上的厚度较小，也即是通过较小的支撑结构就能够实现对悬翼板110的支撑和限位作用。
支撑结构的结构形式具有多种，如图7以及图8，更具体地，支撑结构为设置承载部111背离触摸板130的一侧的至少一个支撑柱160,每一支撑柱160与承载部111背离触摸板130的表面相抵接，并且每一支撑柱160锁紧于承载部111。
上述触控反馈模组100中，支撑柱160用于支撑悬翼板110，为悬翼板110提供振动的支点，通过支撑柱160的设置能够为整体构造提供支撑，同时，悬翼板110的悬翼部112与支撑柱160之间存在夹角，由于两悬翼部112向下振动时，受到该夹角的限制，因此，支撑柱160限制了悬翼板110两侧边缘的振动幅度。在具体设置时，支撑柱160可以采用胶水粘接、螺纹锁紧、凹凸卡扣的方式锁紧于悬翼部112。当支撑柱160的数量为1时，支撑柱160的中心线与悬翼部112的中心线XY重合。当支撑柱160 的数量为多个时，多个支撑柱160均匀排布，并且每一支撑柱160的中心线均与悬翼板110的中心线XY平行，或者，多个支撑柱160关于悬翼板110的中心线XY构成对称结构。
支撑结构的结构形式具有多种，如图9以及图10，更具体地，支撑结构为承载部111背离触摸板130的表面具有的至少一个凸出部113。
上述触控反馈模组100中，通过凸出部113能够将悬翼板110安装至其他构件，用于支撑悬翼板110，为悬翼板110提供振动的支点，通过凸出部113的设置能够为整体构造提供支撑，同时，悬翼板110的悬翼部112与凸出部113之间存在夹角，由于两悬翼部112向下振动时，受到该夹角的限制，因此，凸出部113限制了悬翼板110两侧边缘的振动幅度。在具体设置时，当凸出部113的数量为1时，凸出部113的中心线与悬翼部112的中心线XY重合。当凸出部113的数量为多个时，多个凸出部113均匀排布，并且每一凸出部113的中心线均与悬翼板110的中心线XY平行，或者，多个凸出部113关于悬翼板110的中心线XY构成对称结构。
具体的工作场景如下：
压力感知：如图11所示，当有手指按压到触摸板130时，按压力F会通过触摸板130传递到传递结构120上，传递结构120将力均匀地传递给悬翼板110，导致悬翼板110发生弯曲变形，带动压电马达140通过正压电效应产生电压信号并输出。通过理论计算和有限元仿真证明，在按压触摸板130力度F较小时，悬翼部112的较为微弱地变形能够压电马达140感知，使得压力感知灵敏度较高。需要说明的是，压力感知用于感知不同的压力等级，进而实现不同的触控控制，例如压力大则表示右键，压力小则表示左键。在压力感知之前，还包括确定是否有手指发生触摸的触摸感知。
触控反馈：如图11所示，施加电压信号给压电马达140，压电马达140在电压的激励下发生逆压电效应，带动悬翼板110发生弯曲变形，通过传 递结构120将振动传递给触摸板130，使得触摸板130产生整体的上下振动，由于压电马达140设置在传递结构120的内部空间，使得触摸板130能够产生较小的沿层叠方向的位移Δs，提高触控反馈的灵敏度。
在一个或多个实施例中，在悬翼板110和传递结构120的层叠方向上，悬翼板110的边缘与传递结构120的边缘相平齐，如图1-11所示，定义左右两侧的连线为第一方向Z，悬翼板110在平行于第一方向Z的延伸长度与传递结构120在平行于第一方向Z的延伸长度相等。进一步地，悬翼板110与传递结构120为一体式结构。
上述触控反馈模组100中，由于悬翼板110超出传递结构120的边缘的部分在触摸板130按压时并不能够产生有效的变形，因此，通过将悬翼板110的边缘与传递结构120的边缘相平齐能够减少按压时不能产生有效变形的悬翼板110面积，在保证同样触控反馈效果的基础上，有效地提高触控反馈模组100的小型化程度。
如图12所示，悬翼板110与传递结构120可以设置为一体式结构，以进一步提高触控反馈模组100的小型化程度，并且减少了制备工序和组装工序。在具体设置时，为了在保证传递结构120具有良好的传递效果的情况下消除悬翼板110变形带来的影响，传递结构120可以采用泡棉、橡胶、塑料等具有弹性的材料，硬度小于80A，以消除悬翼板110变形带来的影响。
在一个或多个实施例中，在悬翼板110和传递结构120的层叠方向上，触摸板130的边缘与传递结构120的边缘相平齐，如图1-11所示，定义左右两侧的连线为第一方向Z，触摸板130在平行于第一方向Z的延伸长度与传递结构120在平行于第一方向Z的延伸长度相等。进一步地，触摸板130与传递结构120为一体式结构。
上述触控反馈模组100中，由于触摸板130超出传递结构120的部分不能使传递结构120产生有效作用力，因此，触摸板130的边缘与传递结 构120的边缘相平齐，能够减少按压时不能使传递结构120产生有效作用力的触摸板130面积，进而有效地提高触控反馈模组100的小型化程度。
如图13所示，传递结构120可以与触摸板130一体形成，以进一步提高触控反馈模组100的小型化程度，并且能够减少制备工序和组装工序。在具体设置时，传递结构120和悬翼板110之间弹性连接，以在保证传递结构120具有良好的传递效果的情况下消除悬翼板110变形带来的影响，传递结构120可以采用泡棉、橡胶、塑料等具有弹性的材料，硬度小于80A，以消除悬翼板110变形带来的影响。传递结构120也可以采用刚性材料，然后在传递结构120与悬翼板110之间设置弹性胶以实现连接，其中，弹性胶可以为OCA光学胶、OCR光学胶、双面胶等，这样既可以保证传递结构120具有良好的传递效果，而且传递结构120与触摸板130之间的弹性胶具有一定的弹性可以消除悬翼板110变形带来的影响。
在一个或多个实施例中，触控反馈模组100还包括驱动电路板170，驱动电路板170设置在悬翼板110，且与压电马达140电连接，用于为压电马达140提供电压信号和传递电压信号，以实现逆压电效应和正压电效应的正常运作。
上述触控反馈模组100中，驱动电路板170与压电马达140通过电极线相连接，触控反馈通过驱动电路板170经由电极线施加电压信号给压电马达140进而实现悬翼板110及触摸板130的振动，压力感知通过触摸板130及悬翼板110将力信号传递给压电马达140产生电压信号经由电极线传递给驱动电路板。
具体地，悬翼板110具有多个通孔，驱动电路板170设置在悬翼板110背离压电马达140的表面上，并且驱动电路板170通过位于通孔内的导电件180与压电马达140电连接，以将压电马达140、悬翼板110和驱动电路板170集成在一起。进一步地，悬翼板110和驱动电路板170为一体式结构，以进一步提高触控反馈模组100的小型化程度。
上述触控反馈模组100中，驱动电路板170可以为柔性电路板，将柔性电路板设置于悬翼板110远离压电马达140的一侧，在悬翼板110上设置多个通孔，并在通孔内设置导电件180使得柔性电路板与压电马达140实现电连接，具体地，导电件180可以是注入在通孔内的导电材料，例如银浆、碳浆等导电浆料，也可以通过涂布在通孔内壁上的导电线。并且此时还悬翼板110起到增加柔性电路板强度的作用，当然，驱动电路板170并不局限于柔性电路板，还可以为其它能够满足要求的结构件，如驱动电路板170可以放置在整个结构的外围，与主板整合在一起。
为了进一步提高触控反馈模组的小型化程度，在一个或多个实施例中，悬翼板110可以采用金属合金或工程塑料制备。
上述触控反馈模组100，由于金属合金具有轻质和高强度特点，而由于工程塑料具有刚性强、机械性能好等优点，采用金属合金或工程塑料制备的悬翼板110整体构造的质量较轻，机械强度较强，在较薄的厚度就能够较好地支撑设置于其上的传递结构、压电马达等结构件，提高了支撑的可靠性，增加了触控反馈模组100的使用寿命，以便于实现提高触控反馈模组100的轻薄化和小型化程度，在具体设置时，金属合金可以选择钛合金，铝合金，镁合金，工程塑料可以为高分子聚丙烯、PE(聚乙烯)、PVC(聚氯乙烯)、ABS(丙烯腈-丁二烯-苯乙烯)等；当然制备悬翼板110的材料并不局限于金属合金和工程塑料，还可以为电木、玻璃、不锈钢等满足需要的材料。
本申请的实施例还提供了一种触控装置，包括如上任一实施例的触控反馈模组100。触控装置包括但不限于笔记本电脑、手机、车载设备等需要触控反馈和压力感知的装置。例如，如果触控装置为笔记本电脑，则触控反馈模组100为笔记本电脑的输入触控反馈模组，也称为PC触控反馈模组。
上述触控装置中，由于触控反馈模组100能够在传递结构120围成的 有限空间内集成较多的功能，进而提高触控反馈模组100的小型化程度；并且悬翼部112的较为微弱地变形能够被压电马达140感知，触摸板130能够产生较小的沿层叠方向的位移，提高压力感知和触控反馈的灵敏度，因此具有该触控反馈模组100的触控装置的小型化程度以及灵敏度较高。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请的保护范围应以所附权利要求为准。
