为了能够在小型化和整体化的基础上能够保证整个GPS定位机构的散热效果，在本申请中提出了一种GPS定位机构，其涉及一种新的GPS定位机构的布置方式，图1为本发明实施例中GPS定位机构的结构示意图，如图1所示，该GPS定位机构可以包括：金属框架1，金属框架1具有底壁11和侧壁12，金属框架1形成有一开口13和腔室14；设置在腔室14中并与金属框架1的底壁11相接触的控制模块2；安装在金属框架1的侧壁12形成的开口13处的GPS天线3；安装在GPS天线3上与GPS相接触的GPS模块4。
本申请中的GPS定位机构将GPS天线3、GPS模块4以及控制模块2同时安装在金属框架1上，从而使得四者形成一整体，从而便于将整个GPS定位机构直接安装在其它机器上。其次，本GPS定位机构无需设置额外的散热片或散热件等进行散热，控制模块2通过金属框架1进行散热，GPS模块4则通过GPS天线3进行散热，金属框架1又与GPS天线3连接在一起，因此，GPS天线3、GPS模块4、控制模块2和金属框架1形成一热量传递系统，GPS模块4控制模块2产生的热量能够高效快速的通过金属框架1以及GPS天线3的上表面进行散热，从而能够保证整个GPS定位机构的散热效果。
为了能够更好的理解本申请中的GPS定位机构，下面将对其做进一步解释 和说明。如图1所示，金属框架1用于形成GPS定位机构的外部框架，其具有一定的强度，从而保证整个GPS定位机构中的其它部件不易受到损坏。整个金属框架1大致可以呈筒状，其具有底壁11和侧壁12。金属框架1的底壁11和侧壁12上等均具有镂空结构，从而大幅减少金属框架1的重量。金属框架1的底壁11和侧壁12形成一腔室14，在腔室14可以用于容纳或安装控制模块2以及GPS模块4等。金属框架1的侧壁12在底壁11的另外一端形成有一开口13，该开口13用于安装GPS天线3。
如图1所示，控制模块2设置在金属框架1形成的腔室14中，控制模块2安装在金属框架1的底壁11上。控制模块2与金属框架1的底壁11相接触紧贴，如此，控制模块2在运行时发出的热量能够尽可能的传递至金属框架1的底壁11上，通过金属框架1可以对控制模块2进行散热，进而可以降低控制模块2的温度。控制模块2可以固定连接在金属框架1的底壁11上，从而使得控制模块2与金属框架1之间保持足够的强度，例如，可以通过螺丝6等固定件将控制模块2安装在金属框架1的底壁11上。为了使得控制模块2与金属框架1的底壁11之间具有更好的热传导，在一种可行的实施方式中，控制模块2与金属框架1的底壁11之间填充有导热硅脂。为了提高金属框架1的散热效率以及降低金属框架1的重量，在一种优选的实施方式中，金属框架1优先选择铝或铝合金材料制成。
如图1所示，GPS天线3安装在金属框架1的侧壁12形成的开口13处。具体而言，GPS天线3可以呈片状，GPS天线3的形状可以与金属框架1的侧壁12形成的开口13的形状相对应，从而可以使得两者相匹配。例如，在一种可行的实施方式中，GPS天线3的边缘与金属框架1的侧壁12的端部相接触并固定连接，可以通过螺丝6等固定件将GPS天线3的边缘与金属框架1的侧壁12的端部相固定，同时使得GPS天线3与金属框架1的侧壁12的端部相接触紧贴。通过上述方式可以使得GPS天线3与金属框架1的侧壁12之间可以充分的进行热传导，从而便于两者之间的热量传递。
如图1所示，GPS模块4安装在GPS天线3上，并且与GPS相接触。GPS模块4可以通过螺丝6等固定件固定连接在GPS天线3的两个面的其中一个面上。或者GPS模块4也可以焊接在GPS天线3的两个面的其中一个面上，从而使得GPS模块4与GPS天线3一体化构造，如此，可以免去GPS模块4与GPS天线3之间的连接线。
一般而言，GPS模块4位于金属框架1形成的腔室14中，如此，一方面可以避免GPS模块4出现损坏，另外一方面，当GPS模块4运行发热以后，其热量可以传递给GPS天线3，由于GPS天线3呈片状，其具有较大的面积，因此，GPS天线3背向底壁11的一面能够充分的与外界进行热交换，从而有助于提高散热效率。
为了使得GPS模块4与GPS天线3之间具有更好的热传导，在一种可行的实施方式中，GPS模块4与GPS天线3之间可以填充有导热硅脂等一类能够提高导热性的导热介质。
GPS天线3具有传输信号和散热两重功能，GPS天线3本身具有较大的散热面积，且GPS天线3本身能够与外界接触从而释放热量，当GPS模块4发热温度上升后，其能够立马通过GPS天线3进行散热。而控制模块2则与金属框架1接触贴紧设置，控制模块2能够通过金属框架1进行散热。与此同时，由于金属框架1又与GPS天线3连接在一起，GPS天线3、GPS模块4、控制模块2和金属框架1形成一热量传递系统，即金属框架1、GPS天线3均能够对GPS模块4、控制模块2进行散热，当控制模块2温度过高，金属框架1散热量有限时，其能够将热量及时传递给GPS天线3，通过GPS天线3进行辅助散热。当GPS模块4温度过高，GPS天线3热量有限时，其又能够将热量及时传递给金属框架1，通过金属框架1进行辅助散热。金属框架1、GPS天线3两者能够进行耦合相互弥补，从而实现对GPS模块4、控制模块2的均衡散热。
在一种可行的实施方式中，如图1所示，金属框架1外可以设置有外壳5，该外壳5可以包覆在金属框架1上，从而对金属框架1的内部进行密封，保护 GPS模块4和控制模块2。外壳5与金属框架1之间可以通过螺丝6相固定。外壳5可以由塑料或金属制成。当外壳5选用塑料时，其可以大幅降低整个GPS定位机构的重量，满足用户的轻便性要求，也有利于GPS天线3传输信号。当外壳5选用金属时，外壳5与金属框架1相接触在一起，外壳5同样能够起到较好的散热作用，有处于提高整个GPS定位机构的散热性能。
另外，壳体上可以设置有接口51，该接口51用于与外部其它设备相连接，用于对GPS定位机构进行供电、数据交换等。接口51与控制模块2相电性连接，同时，控制模块2与GPS模块4相电性连接，GPS模块4与GPS天线3相电性连接。
在本申请中还提出了一种割草机，该割草机包括：如上述任一的GPS定位机构。GPS定位机构用于对割草机进行定位，从而实现割草机对某一区域内的全自动智能割草。GPS定位机构中的GPS天线3用于接收卫星系统的定位数据，卫星系统可以是北斗、GPS、伽利略、格洛纳斯等等。定位数据经过GPS模块4解析，预处理后得到高精度定位数据，高精度定位数据连接线等传输到控制模块2，控制模块2通过这些数据可以进行建图、导航和/或规划路经等等。控制模块2再传输给割草机，割草机根据控制模块2的指令数据运动行走，从而自行完成区域内的智能割草。
割草机中具有芯片等发热元件，这些发热元件上会安装有散热片，该散热片用于对割草机的发热元件进行散热。在一种可行的实施方式中，GPS定位机构可以与散热片相接触设置，从而再利用割草机的散热片再对GPS定位机构进行散热。例如，散热片可以与GPS天线3相接触。散热片可以与金属框架1相接触。当金属框架1外设置有外壳5，外壳5由金属制成时，散热片可以与外壳5相接触。通过上述方式，可以对割草机的散热片进行综合利用，从而加强对GPS定位机构的散热，保证其运行正常，避免温度升高过多。
