技术领域
本发明涉及电控执行器技术领域，特别涉及一种角行程电控执行器。还涉及一种包含该角行程电控执行器的车辆。
背景技术
电控执行器是指在控制系统中以电为能源的一种执行器，角行程电控执行器属于电控执行器中的一种。角行程电控执行器又分为带角度传感器和不带角度传感器两大类。
对于带角度传感器的角行程电控执行器，当应用到车辆中时，通常采用非接触式角度传感器，如图1所示，角行程电控执行器主要包括壳体2、转轴1、齿轮3、角度传感器4和电路。其中，转轴1转动连接于壳体2的转轴孔中；齿轮3固定于转轴1上；角度传感器4主要包括信号发射单元41和信号接收单元42，信号发射单元41通常固定在转轴1的末端，随转轴1一起转动，用于持续发射信号，辨别角度；信号接收单元42固定在壳体2上，且靠近信号发射单元41所在转轴1轴端设置，位置固定不动，信号接收单元42与电路相连，工作时，信号发射单元41相对信号接收单元42发生角位移，信号接收单元42用于接收、处理 并输出角度信号。
在此情况下，当转轴1的输出端受到如图1所示的径向力F时，支撑转轴1的主要受力部分为壳体2的转轴孔。这种角行程电控执行器就要求壳体2采用强度较高的材质，成本较高，且固定转轴1的转轴孔必须足够深，才能保证转轴1运行的稳定性。
综上所述，如何解决现有角行程电控执行器的成本高，壳体受力不合理导致的结构设计受限的问题，成为了本领域技术人员亟待解决的问题。
发明内容
有鉴于此，本发明的目的在于提供一种角行程电控执行器，以降低其成本，同时优化壳体受力情况，使结构设计不受限制。
为达到上述目的，本发明提供以下技术方案：
一种角行程电控执行器，包括转轴组件、壳体2和角度传感器，所述角度传感器包括信息发射单元和信息接收单元；所述转轴组件的两端转动支撑于所述壳体上，所述信息发射单元设置于所述转轴组件的非轴端上，所述信息接收单元固定于所述壳体上且靠近所述信息发射单元所在的位置，所述信息发射单元和所述信息接收单元均位于所述壳体的两个转动支撑点之间。
优选的，在上述的角行程电控执行器中，所述转轴组件包括转轴和齿轮，所述转轴的两端转动支撑于所述壳体上，所述齿轮固定于所述转轴上，且所述齿轮位于所述壳体的两个转动支撑点之间，所述信息发射单元设置于所述转轴的非轴端上或齿轮上。
优选的，在上述的角行程电控执行器中，所述信息发射单元为相对所述转轴的轴线对称结构。
优选的，在上述的角行程电控执行器中，所述信息发射单元的磁铁上设置有保持连接部，所述磁铁通过所述保持连接部嵌装固定于所述齿轮上。
优选的，在上述的角行程电控执行器中，所述保持连接部为锯齿状结构。
优选的，在上述的角行程电控执行器中，所述转轴组件通过滑动轴承或滚 动轴承转动支撑于所述壳体上。
优选的，在上述的角行程电控执行器中，所述壳体与所述转轴组件转动配合的转轴孔处为塑料结构。
本发明还提供了一种车辆，包括角行程电控执行器，所述角行程电控执行器为如以上任一项所述的角行程电控执行器。
与现有技术相比，本发明的有益效果是：
本发明提供的角行程电控执行器中，转轴组件的两端转动支撑于壳体上，相应地，信息发射单元设置于转轴组件的非轴端上，信息接收单元固定于壳体上且靠近信息发射单元所在的位置，且信息发射单元和信息接收单元均位于壳体的两个转动支撑点之间。可见，转轴组件通过壳体进行两点转动支撑，因此，转轴组件的转动更加平稳，且不需要在壳体上设置较深的转轴孔，从而壳体的结构设计不受局限，且采用转轴组件的两端转动支撑于壳体上，优化了壳体的受力情况，壳体不需要采用成本较高的金属，增加了转轴组件的径向受力强度，在此基础上，由于空间的限制，信息发射单元和信息接收单元不能设置在转轴组件的轴端，只能设置在非轴端。
本发明提供的车辆中，采用了该申请中的角行程电控执行器，因此，更加方便角行程电控执行器的布置，车辆运行更加可靠。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。

图2为本发明实施例提供的一种角行程电控执行器的结构示意图；
图3为本发明实施例提供的一种角行程电控执行器的信号发射单元的安装结构示意图；
图4为本发明实施例提供的一种角行程电控执行器的磁路模拟示意图；
图5为本发明实施例提供的一种角行程电控执行器的转轴受力分析示意图。
其中，1为转轴、2为壳体、3为齿轮、4为角度传感器、41为信息发射单元、411为提磁铁、412为锯齿状连接部、42为信息接收单元。
具体实施方式
本发明的核心是提供了一种角行程电控执行器，降低了其成本，同时优化了壳体受力情况，使结构设计不受限制。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图2，本发明实施例提供了一种角行程电控执行器，包括转轴组件、壳体2和角度传感器4。其中，转轴组件的两端转动支撑于壳体2上，壳体2上开设有两个转轴孔，分别用于与转轴组件的两端转动配合连接；角度传感器4包括信息发射单元41和信息接收单元42，信息发射单元41设置于转轴组件的非轴端上，对应地，信息接收单元42固定于壳体2上且靠近信息发射单元41所在的位置，信息发射单元41和信息接收单元42均位于壳体2的两个转动支撑点A和B之间，即位于两个转轴孔之间。
工作时，转轴组件相对壳体2做旋转运动，信息发射单元41随转轴组件旋转，而信息接收单元42相对壳体2保持相对静止，则在此过程中，信息发射单元41和信息接收单元42发生相对角位移，从而可以测量并输出角度值。
由于本申请中的角行程电控执行器的转轴组件的端部通过壳体2进行两点转动支撑，因此，转轴组件的转动更加平稳，且不需要在壳体2上设置较深的转轴孔，从而壳体2的结构设计不受局限，且采用转轴组件的两端转动支撑于壳体2上，优化了壳体2的受力情况，壳体2不需要采用强度高但成本较高的材质，增加了转轴组件的径向受力强度。在此基础上，由于空间的限制，信 息发射单元41和信息接收单元42不能设置在转轴组件的轴端，只能设置在非轴端。
具体地，转动组件的受力分析如图5所示，在转轴1的一端施加作用力F，两个转动支撑点A和B分别需要支撑力F A和F B，作用力F的施加点与转动支撑点A之间的距离为L1，转动支撑点A和B之间的距离为L2。则存在以下等式：
F A＝F+F B；
F*L1＝F B*L2；
求解的F A＝F(L1/L2+1)。
其中，L1的长度由产品应用环境限制，一般为定值，则根据公式判断得出，如果L2越大，那么F A越小，即转动支撑点A所需要的支撑力越小，F B也具有同样的结果。采用两点支撑，能够优化壳体2的受力情况。
与现有的角度传感器相比，本发明的角度传感器4的信息发射单元41和信息接收单元42并不是布置在轴端，则角度传感器4的信息发射单元41的磁路相应发生变化，以达到执行器信号线性输出的要求。
具体地，磁场的X方向的磁感应强度为Bx，Y方向的磁感应的强度为By，Z方向的磁感应强度为Bz。角度传感器4对磁场不同方向的磁感应强度Bx、By强度求正切，可获得信息发射单元41相对于信息接收单元42转过的相对角度。
从图4的磁路模拟上来看，Bx基本满足正弦曲线，By基本满足余弦曲线，可得信号输出和角度关系的线性度较好，能满足正常使用要求。
在本实施例中，转轴组件包括转轴1和齿轮3，转轴1的两端转动支撑于壳体2上，齿轮3固定于转轴1上，且齿轮3位于壳体2的两个转动支撑点之间，齿轮3带动转轴1相对壳体2做旋转运动；信息发射单元41设置于转轴1的非轴端上或齿轮3上，即信息发射单元41设置于转轴1的轴壁上，或者设置在齿轮3的任意一端侧面上。相应地，信息接收单元42设置在壳体2的平行于转轴1轴线的侧壁上。只要能够使信息发射单元41和信息接收单元42发生相对角位移并接受、输出角度信息即可。
进一步地，在本实施例中，信息发射单元41为相对转轴1的轴线对称结构，信息发射单元41对称设置于转轴1上能够使转轴1运行更加平稳。当然，信息发射单元41也可以为非对称结构。
如图3所示，为了实现信息发射单元41的磁铁同轴布置于转轴1的圆周上，在本实施例中，信息发射单元41的磁铁411采用嵌件注塑的方式，即在磁铁411上加工特定的保持连接部412，如图3中所示的锯齿状结构，或者保持连接部412为具有多个轴向凸起的结构，磁铁411的保持连接部412在齿轮3注塑的时候与齿轮3一体成型，磁铁411通过保持连接部412嵌装固定于齿轮3上，这种结构具有精度高，鲁棒性好，成本低等优势。
在本实施例中，转轴组件通过滑动轴承或滚动轴承转动支撑于壳体2上，从而使转轴组件转动平顺，当然，转轴组件还可以通过其它转动连接方式转动支撑于壳体2上，如轴套转动配合等。
在本实施例中，壳体2与转轴组件转动配合的转轴孔处为塑料结构，由于转轴组件的两端转动支撑于壳体2上，因此，壳体2的受力情况得到优化，因此，在相同径向力条件下，壳体2部分采用塑料结构，完全能够承受受力强度，从而可以不需要采用成本较高的金属，降低了成本。
基于以上任一实施例所描述的角行程电控执行器，本发明实施例还提供了一种车辆，包括角行程电控执行器，且该角行程电控执行器为以上任一实施例所描述的角行程电控执行器。由于角行程电控执行器的结构不受限制，从而可以更加方便角行程电控执行器的布置，且该角行程电控执行器的壳体受力情况得到优化，转轴1运行平稳，从而使车辆运行更加可靠。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
