请参考图1和图2，图1是本发明扫描成像***一实施例的结构示意图，图2是本发明扫描成像***的驱动装置200一实施例的结构示意图。如图1所示，本实施例的扫描成像***包括扫描装置100和驱动装置200，扫描装置100用于对待扫描物体进行扫描；驱动装置200包括驱动电机201和运动组件，其中，运动组件与驱动电机201连接，扫描装置100与运动组件连接，运动组件作为驱动电机201和扫描装置100之间的驱动枢纽，在驱动电机201的驱动下带动扫描装置100运动。进一步参阅图2，如图2所示，本实施例的运动组件上设置有顺序排列的若干个制动件204，制动件204在扫描装置100运动时按预设顺序逐一开启，当制动件204开启时会触发扫描装置100在当前的位置上暂停运动，并在该位置上对待扫描物体进行扫描。
进一步参考图1，本实施例的扫描成像***还包括旋转组件300，旋转组件300分别与扫描装置100和驱动装置200连接，进而在驱动装置200的驱动下带动扫描装置100旋转，以对待扫描物体进行扫描。在其他实施方式中，扫描装置100也可以直接连接驱动装置200的运动组件，直接通过运动组件带动运动。
进一步的，本实施例的扫描装置100包括支撑框架101和扫描天线阵列102，扫描天线阵列102安装在支撑框架101的内侧，支撑框架101的内部空间可容纳待扫描物体，扫描天线阵列102的信号发射方向朝向支撑框架101中容置待扫描物体的空间位置；进一步，扫描天线阵列102包括相邻设置的发射天线阵列和接收天线阵列，两者并排设置，以方便收发信号，保障信号收发质量。本实施例中，扫描天线阵列102向待扫描物体反射的扫描信号可以为毫米波扫描信号和/或太赫兹扫描信号。如图1所示，旋转组件300与扫描装置100的支撑 框架101固定连接，驱动装置200的运动组件在驱动电机201的驱动下驱动旋转组件300旋转，旋转组件300带动支撑框架101旋转，以使支撑框架101内侧设置的扫描天线阵列102能够进行往返的圆周运动，进而对位于支撑框架101内部的待扫描物体进行0～360°的固定角度范围或全方位的扫描。
进一步参阅图2和图3，图3是图2所示的驱动装置200的俯视结构示意图。如图2和图3所示，本实施例的运动组件包括安装座202、设置于安装座202上的安装槽217、设置于安装槽217内并与驱动电机201连接的丝杆215、与丝杆215连接的滑动块(位于滑动板213下方，图3中未画出)以及与滑动块连接的滑动板213，滑动板213与安装座202滑动连接。驱动装置200工作时，驱动电机201驱动丝杆215旋转，丝杆215带动滑动板213沿安装座202的延伸方向直线滑动，驱动电机201能够正转或反转以驱动滑动板213在安装座202上进行往返运动。若干个制动件204设置在安装座202的外壁，其延伸方向与安装座202的延伸方向相同(即制动件204的设置方向与滑动板213的滑动路径一致)，滑动板213的侧面设置有限位块205。当滑动板213沿安装座202的延伸方向直线滑动时，若干个制动件204按预设顺序逐一开启，开启的制动件204会与限位块205接触，进而触发驱动电机201暂停工作，运动组件也随之暂停运动，扫描装置100则失去了驱动力进而也暂停运动，此时扫描控制其则控制扫描天线阵列102对待扫描物体进行扫描。
本实施例中，预设顺序为从安装座202的靠近驱动电机201的一端到远离驱动电机201的一端，或从安装座202的远离近驱动电机201的一端到靠近驱动电机201的一端，具体需要根据运动组件的滑动板213在开始运动时的位置，以及其滑动方向，若滑动板213的初始位置靠近驱动电机201，则预设顺序为从安装座202的靠近驱动电机201的一端到远离驱动电机201的一端，否则预设顺序相反。
进一步的，本实施例中若干个制动件204逐一开启的时间间隔可以根据需要扫描的次数、驱动电机201驱动滑动板213运动的速度以及支撑框架101在驱动电机201的作用下的角速度等进行设置。本实施例中令滑动板213从一个制动件204运动到响铃的另一个制动件204所需的时间与支撑框架101运动预设扫描角度所需的时间相同。假设扫描装置100的预设扫描角度为30°(即，每旋转30°则对待扫描物体进行一次扫描)，而扫描装置100的角速度和滑动板213运动的速度均为已知数据，则可以计算得到相邻两个制动件204开启的间隔时 间。由此，当滑动板213从一个制动件204运动到相邻的另一个制动件204时，扫描装置100相应的旋转预设扫描角度，此时该另一个制动件204开启，即可使滑动板213暂停运动，进而令扫描装置100在当前位置上暂停运动，进而实现扫描装置100每旋转预设扫描角度即在当前位置上对待扫描物体进行扫描的目的，实现对待扫描物体的的0～360°的固定角度范围或全方位的扫描。
在一实施方式中，可以通过令若干个制动件204连接一控制器(图中未画出)，通过该控制器对滑动板213的运动时间进行计时，当计时的时长达到设置的间隔时间时，则开启制动件204。进一步的，控制器在开启制动件204的同时，可以向驱动电机201发送暂停驱动的指令，以使驱动电机201暂停工作，避免当制动件204与滑动板213上的限位块205接触后滑动板213继续运动，导致运动组件的损害。进一步的，控制器还可以对扫描天线阵列102进行控制，即当其开启制动件204时向扫描天线阵列102发送扫描指令，以使扫描天线阵列102对待扫描物体进行扫描；本实施例中，当扫描天线阵列102接收到待扫描物体反射回的回波信号时，向控制器进行反馈，控制器则将当前开启的制动件204关闭，并向驱动电机201发送工作指令，以使驱动电机201继续工作，重复上述的过程直至完成对待扫描物体的0～360°的固定角度范围或全方位的扫描，得到待扫描物体的立体扫描数据。其中，控制器可以单独设置，也可以与驱动电机进行集成。
进一步的，本实施例还可以通过在安装座202上设置感应部件(图中未示出)，感应部件的位置与制动件204的位置一致，当滑动板213运动到感应部件的位置处时，即触发开启与感应部件的位置一致的制动件204，进而令扫描装置100暂停运动；实现原理与上述相同，此处不再赘述。本发明中感应部件可以为传感器件或机械制动部件。
本实施例中，制动件204可以为弹射制动件204或旋转制动件204，即制动件204可以通过旋转或弹射的方式开启，并与滑动板213侧面上的限位块205接触。
进一步参阅图2和图3，如图2和图3所示，本实施例中的安装槽217的两侧顶部设置有沿安装槽217同向延伸的滑动轨道212，滑动轨道212上设置有滑动块203，滑动块203相对于滑动轨道212滑动，滑动块203与滑动板213固定连接。
本发明的另一实施方式中，若干个制动件204可以沿滑动轨道212设置， 且位于滑动轨道212上，同样，若干个制动件204在扫描装置100运动的过程中逐一开启，并与设置在滑动轨道212上的滑动块203接触，触发运动组件暂停运动，进而令扫描装置100随之暂停运动，并在暂停的位置上对待扫描物体进行扫描，之后继续工作，重复上述的过程直至完成对待扫描物体的0～360°的固定角度范围或全方位的扫描。本实施方式中的制动原理与上述的制动原理相同，此处不再赘述。本实施方式中，若干个制动件204设置在滑动轨道212上沿其延伸方向分布的凹槽内，当制动件204被开启时，制动件204从凹槽中弹起，此时制动件204顶部高于滑动轨道212的顶部，进而与滑动到此处的滑动块203接触。
进一步参阅图3，如图3所示，安装槽217内设置有用于连接丝杆215与驱动电机201的联轴器216及用于支撑丝杆215的支架214，支架214设置于丝杆215的端部并与丝杆215转动连接，联轴器216设置于丝杆215与驱动电机201之间。联轴器216可增加驱电机与丝杆215连接的稳定性，提高传动的可靠性和同步性，并且在后期维护时，可提高拆卸的便捷性。
进一步参阅图4和图5，图4是本发明扫描成像***的旋转组件300一实施例的结构示意图，图5是图4所示的旋转组件300的侧视图。如图4所示，旋转组件300包括连接板301、齿轮303、齿轮安装座302及转动安装于齿轮安装座302并与齿轮303固定连接的连接轴304。连接板301与齿轮303固定连接，且连接于扫描装置100的支撑框架101，进而在齿轮303转动时带动支撑框架101旋转运动。
进一步参阅图1，如图1所示，驱动装置200还包括用于与旋转组件300的齿轮303啮合并带动齿轮303旋转的齿条组件，齿条组件与滑动板213固定连接。通过齿条组件与齿轮的配合，可提高传动机构的传动准确性。
具体的，滑动板213上设置有用于安装齿条组件的安装板206，安装板206的两端分别向背离滑动板213的一侧弯折，并从此两弯折部211，两弯折部211上均螺纹连接有多个用于抵接齿条组件的定位螺栓207，齿条组件包括设置于两弯折部211之间并相互堆叠设置的第一齿条209和第二齿条210，第一齿条209与第二齿条210平行设置，第一齿条209两端部分别对应于两弯折部211间隙安装，多个定位螺栓207分别与第一齿条209的两端抵接，第二齿条210的两端部分别对应与两弯折部211间隙安装，多个定位螺栓207分别与第二齿条210的两端抵接。
在实际应用中，第一齿条209和/或第二齿条210与齿轮303啮合时会存在齿侧间隙，且当扫描成像***使用一段时间后，由于机械磨损原因，会令第一齿轮209和/或第二齿轮210与齿轮303啮合时产生齿侧间隙，当第一齿轮209和/或第二齿轮210改变转动方向时，齿轮303由正转变换为反转时或由反转变换为正转时，齿侧间隙会产生冲击和机械振动，并带来噪音。本发明实施例的扫描成像***，可通过调节定位螺栓207并移动第一齿条209和/或第二齿条210，使齿轮303与齿条组件完全啮合并消除齿侧间隙，减小冲击和机械振动，降低噪音，并提高扫描成像***的使用寿命。
进一步参阅图1，如图1所示，本实施例的扫描成像***还包括用于安装驱动电机201和齿轮安装座302的承载板208。
在另一实施方式中，第一齿条209和第二齿条210还可以分别设置在齿轮303的两侧，驱动装置以及旋转组件的其他结构均相同并且数量为上述实施例的两倍，第一齿条209安装于其中一安装板206上，第二齿条210安装于另一安装板206上，位于齿轮303两侧的第一齿条209和第二齿条210均相互平行设置。
以上仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围。
