本申请涉及设备标定技术领域，尤其涉及一种位移装置以及包括所述位移装置的汽车标定设备。
背景技术
当前，车辆的辅助驾驶系统可以用于对车辆的行驶进行辅助，实现车辆行驶的智能化。车辆的辅助驾驶系统可以包括雷达、照相机等多种传感器，用于感应车辆周围环境。其中，雷达、照相机等传感器在车辆上的位置，决定了其感应周围环境的精准度。因此，需要对车辆的辅助驾驶系统在车辆上的位置进行标定或校准。在此，可以利用标定装置对上述传感器进行标定，标定装置包括标定支架，用于支撑对各传感器进行标定的标定件，例如，在标定雷达时，需要支撑雷达标定件，如三角反射器、图案反射板等标定件。目前市面上出现通用的标定装置，该通用的标定装置可以适用于多种车辆，由于传感器在车辆上的安装位置不尽相同，因此，标定支架上设置有导轨，可以实现标定件挂载在导轨的不同位置上，进而实现对不同车辆上的传感器进行标定，通常，标定支架上安装有位移装置，位移装置用于承载标定件，以实现标定件处于导轨上的不同位置。
而现有技术中，位移装置多采用导轨滑块方式以及T型槽方式进行位移。而在实现本申请的过程中，发明人发现：导轨滑块方式安装比较麻烦，对安装面要求较高，成本较高，并且重量偏重；T型槽方式只能承受轻负载，若负载过重会导致摩擦力太大，位移不顺。

在本实施例中，所述连接部23分别与所述第一滚动机构21、所述第二滚动机构22可拆装连接，以所述导轨10凹设的第一导槽11、第二导槽12为基础，移动所述第一滚动机构21、所述第二滚动机构22，将所述第一滚轮212、所述第二滚轮222分别对应装配进入所述第一导槽11、所述第二导槽12，以能够方便地进行装配，装配简单，使用方便。同时地，所述连接部23上设置有所述挂载孔洞231或所述挂载部，从而增强所述位移组件20的挂载能力，以增强所述位移装置100的使用性能。
