Description

一种制动装置及制动系统 技术领域
本申请涉及车辆制动的技术领域,尤其涉及一种制动装置及制动系统。
背景技术
现有技术中的行程传感器一般采用磁感应原理。当磁铁随着踏板行程的变化发生移动,感应元件(如霍尔)将检测到的磁场变化转换成电信号,然后驱动液压装置输出,磁铁信号易受到制动装置内外部环境干扰,影响霍尔传感器的信号精度。现有技术中为了降低外界环境对行程传感器内的电子器件的影响,将行程传感器组件全部封装一起,对行程传感器进行密封,密封件过于复杂。
申请内容

具体实施方式
为了更好的理解本申请的技术方案,下面结合附图对本申请实施例进行详细描述。
应当明确,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例,都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。
应当理解,本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
需要注意的是,本申请实施例所描述的“上”、“下”、“左”、“右”等方位词是以附图所示的角度来进行描述的,不应理解为对本申请实施例的限定。此外,在上下文中,还需要理解的是,当提到一个元件连接在另一个元件“上”或者“下”时,其不仅能够直接连接在另一个元件“上”或者“下”,也可以通过中间元件间接连接在另一个元件“上”或者“下”。
现有技术中制动装置的行程传感器采用磁感应原理,制动装置设置有永磁体与制动踏板连接,能够随踏板运动。在液压块的一侧设置有感应元件(如霍尔传感器),能够检测永磁体的位置,然后转换成电信号控制制动系统使车辆减速,由于制动装置周围具有杂散电磁场电磁阀、电机定转子和驱动电路等)和导磁部件,会影响感应元件的精度。同时,制动装置采用的永磁体,通常为含稀土元素的钕铁硼材料,成本较高。在制动装置对传感器等电子元件进行密封时,通常在永磁体和制动踏板的连接杆处设置密封件9,由于连接杆会随制动踏板运动,密封件9的结构比较复杂,进而使制动装置的加工成本增加。
基于此,本申请提供了一种制动装置,采用电感应原理,用于解决磁感应原理容易被外界环境影响、制作成本较高,密封件9的结构较复杂的问题。
如图1和图2所示,本申请实施例提供了一种制动装置,包括主体部8、活塞2、目标件3、感应装置4和密封件9,主体部8包括内部设置有活塞缸11的液压块1,活塞2的至少部分位于活塞缸11内且能够沿制动装置的长度方向运动,目标件3与活塞2连接,并能够随活塞2运动,感应装置4能够检测目标件3的位置,密封件9设置于感应装置4外表面。其中,目标件3能够相对于感应装置4运动,感应装置4内设置有激励线圈和感应线圈,激励线圈能够发出交变电磁场,使目标件3内产生涡电流,进而目标件3能够发出交变电磁场,感应线圈能够接收涡电流发出的交变电磁场,从而检测出目标件3的位置。 感应装置4位于主体部8的一侧,密封件9的至少部分位于感应装置4远离主体部8的一侧,且密封件9能够与主体部8连接,以密封感应装置4。
感应线圈接收的涡电流的电磁场频段特殊,通常在1MHz至6MHz之间,由于制动装置周围的杂散磁场在0至400MHz,且频段不稳定,所以影响感应装置4检测目标件3位置的可能较小,提高了制动装置的精确性。在感应装置4外表面设置密封件9使感应装置4与外界隔绝,能够降低感应装置4内进入灰尘或其他杂质而对其电子元件产生影响的风险。本申请的感应装置4不随活塞2运动,所以可以将感应装置4设置于主体部8与密封件9之间,相较于将感应装置4、目标件3和活塞2用同一个密封件9密封的方式,降低了密封的难度。
如图1和图2所示,在一种可能的实施例中,制动装置包括推动部件5,主体部8包括套筒6,推动部件5的一端与活塞2连接,另一端与制动踏板连接,能够驱动活塞2在活塞缸11内运动。套筒6与推动部件5连接,套筒6内设置有腔体61,推动部件5的至少部分能够穿过所述腔体61,腔体61与活塞缸11连通,并且能够在腔体61内运动。
推动部件5一端与活塞2连接,另一端与制动踏板连接,能够使活塞2与制动踏板的运动幅度一致,进而使制动装置能够更加精确地感应制动踏板的运动幅度。推动部件5的至少部分穿过套筒6的腔体61与活塞2连接,能够减少由于外界环境的变化而影响推动部件5的运动轨迹的可能。
如图3和图4所示,在一种可能的实施例中,推动部件5包括安装支架51,安装支架51的至少部分能够伸入液压块1。安装支架51的一端与活塞2连接,能够随活塞2运动,另一端与目标件3连接,能够驱动目标件3在运动。感应装置4安装于液压块1的一侧,感应装置4远离液压块1的一侧设置有密封件9,密封件9的侧壁均能够与液压块1连接,以密封感应装置4,目标件3也能够随活塞2在液压块1内相对于感应装置4运动。
感应装置4安装于液压块1,在沿制动装置高度方向的投影中,目标件3的投影在感应装置4的投影范围内,通过安装支架51,目标件3能够随活塞2运动,并且能够相对液压块1运动,可以使感应装置4能够检测目标件3的位置,进而检测出制动踏板的运动幅度。密封件9将感应装置4密封能够降低外界环境对感应装置4造成损坏的风险,有助于延长感应装置4的使用寿命。
如图3和图4所示,在一种可能的实施例中液压块1设置有第一安装槽12,感应装置4和密封件9均位于第一安装槽12内。
将感应装置4和密封件9均安装于第一安装槽12内,能够降低感应装置4相对于液压块1运动的可能。感应装置4的安装方式可以为螺丝固定、卡扣固定、过盈固定或压铆固定,可以使感应装置4与第一安装槽12固定的更加稳定。
如图3和图4所示,在一种可能的实施例中,安装支架51的至少部分能够穿过腔体61,且能够在腔体61内运动。套筒6内设置有与腔体61连通的第一定位凹槽62,安装支架51设置有第一定位块511,第一定位块511的至少部分能够伸入第一定位凹槽62,且能够在第一定位凹槽62内运动。
通过第一定位凹槽62与第一定位块511的配合,可以降低安装支架51在套筒6内转动的可能,从而限制目标件3与感应装置4之间的相对运动,降低目标件3相对感应装置4转动的可能,提高了感应装置4对目标件3位置检测的精确性。
如图5、图6和图7所示,在一种可能的实施例中,目标件3沿活塞2的周向设置,且能够随活塞2运动。
将目标件3沿活塞2周向设置,能够省去安装支架51的结构,使目标件3与活塞2连接的方式更加简单,降低了制动装置的生产工序和生产成本,同时,能够使目标件3与活塞2之间连接的更加稳定。
如图5、图6和图7所示,在一种可能的实施例中,感应装置4包括壳体41和感应电路板42,壳体41安装于套筒6外表面。感应电路板42的外表面设置有密封件9,感应电路板42和密封件9均位于壳体41内,且均与壳体41的底壁连接。
由于目标件3在腔体61内运动,所以感应装置4安装于套筒6外表面,能够更加精确地检测目标件3的位置,同时,能够取消液压块1上的第一安装槽12,节省了液压块1内的空间。同时,壳体41还能够对感应电路板42起到一定的密封作用,降低外界环境对感应电路板42造成破坏的风险。
如图8和图9所示,在一种可能的实施例中,套筒6内设置有第二安装槽63,感应装置4的感应电路板42位于第二安装槽63内,腔体61靠近第二安装槽63的一侧设置有第一感应平面611,电路板与第一感应平面611平行。目标件3沿活塞2周向设置,并与活塞2连接。目标件3靠近第一感应平面611的一侧设置有第二感应平面,第一感应平面611与第二感应平面平行。密封件9沿感应电路板42周向设置于感应电路板42的表面,且与第二安装槽63的底壁连接,对感应电路板42起到密封的作用。
将感应装置4的感应电路板42位于第二安装槽63内能够省去感应电路板42的外壳,降低了制动装置的零件数量,进而降低了生产成本。在腔体61内壁和目标件3分别设置第一感应平面611和第二感应平面,能够提高感应装置4对目标件3位置的感应精度。同时,设置密封件9能够分隔感应电路板42和外界环境,对感应电路板42起到保护的作用。
如图9所示,在一种可能的实施例中,目标件3设置有第二定位凹槽32,套筒6设置有第二定位块64,第二定位块64凸出于腔体61内壁。第二定位块64的至少部分能够伸入第二定位凹槽32。
通过第二定位块64和第二定位凹槽32配合能够降低目标件3在腔体61内转动的可能。
如图10所示,在一种可能的实施例中,目标件3设置有感应凸台33,第二感应平面设置于感应凸台33,套筒6设置有与腔体61连通的避让槽65,感应凸台33的至少部分能够伸入避让槽65。
感应凸台33与避让槽65配合能够降低目标件3转动的可能,同时减少了定位槽和定位块的结构,减少了制动装置的加工工序。
如图11所示,在一种可能的实施例中,目标件3设置有感应支架34,第二感应平面位于感应支架34。
感应支架34与目标件3的主体可以通过注塑或压铆的形式连接。
在一种可能的实施例中,密封件9可以为树脂或密封板。
