一种具有报警功能的吸盘 技术领域
本发明涉及吸盘领域，特别是涉及一种具有报警功能的吸盘。

吸盘本体1的上方固定有筒形的外壳2，外壳2的内部滑动密封装配有活塞杆3。外壳2的轴向一端为开口、另一端具有壳底，活塞杆3包括杆体31，杆体31靠近壳底的一端固定有密封皮碗32，活塞杆3通过密封皮碗32与外壳2的内壁滑动密封配合。密封皮碗32与外壳2的底壁之间形成负压腔22，外壳2的底壁上开设有连通吸盘本体1的内腔与负压腔22的连通通道21，使负压腔22与吸盘本体1的内腔的气压保持一致。
活塞杆3还包括设置在杆体31上的杆帽33，杆帽33与杆体31一体成型且布置在杆体31远离外壳2的底壁一端，杆帽33与外壳2的内壁导向配合。杆帽33与杆体31之间具有环形间隙，外壳2的内壁上设置有沿其周向布置的环形挡台34，环形间隙内设置有顶压装配在环形挡台34与杆帽33之间的弹簧35，弹簧35形成顶压装配在活塞杆3与外壳2之间的弹性件；在其他实施例中，弹性件也可以为橡胶筒。在吸盘本体1漏气时，负压腔22以及吸盘本体1的内腔的气压增大，在弹簧35的弹力的作用下，活塞杆3会被推出外壳2；当吸盘本体1内的气体被抽出时，负压腔22与吸盘本体1的内腔的压力小于大气压力，弹簧35被压缩，活塞杆3收回至外壳2内。
行程开关4包括套设在杆帽33上的导电环41和顶压装配在杆帽33与外壳2之间的弹性触指42，弹性触指42共有两个且分别与报警系统的正负极连通。导电环41固定在杆帽33靠近挡台一端的端部，导电环41形成行程开关4的导电件。弹性触指42呈“几”字形，外壳2的内壁带上开设有条形的安装槽，弹性触指42布置在安装槽内，弹性触指42形成行程开关4的触发电极；在其他的实施例中，弹性触指42也可以为圆弧形或者“八”字形。弹性触指42具有弹性，在导电环41与弹性触指42接触时，弹性触指42可增大与导电环41之间的压力，保证电连接可靠。
报警系统包括控制模块和与控制模块信号连接的报警设备。控制模块包括无线发射端和与无线发射端配合的无线接收端，采用无线技术传输信号，结构集成，减少线路，便于车内安装。无线发射端包括布置在吸盘本体1的顶部的电路板5，电路板5为圆形，当然也可以为矩形等其他形状。
电路板5包括主板51和布置在主板51上的电池52、控制芯片53和与控制芯片53信号连接的天线54，两个弹性触指42均布置在电路板5上且分别与电池52的正负极导电连通。控制芯片53负责控制发射端各元器件的逻辑关系，电池52为无线发射端的各个元件提供电源，天线54用于发射信号。天线54为PCB天线54，天线54采用2.4G射频无线传输，工作频率为2.4-2.5GHz；当然，在其他实施例中天线54也可以为外置天线54。
当吸盘从安全状态漏气时，活塞杆3上的弹簧35推动活塞杆3弹出。活塞杆3的滑动行程中，当导电环41和弹性触指42接触时，无线发射端的电池52的正负极导电连通，无线发射端通电工作，控制芯片53驱动天线54向外发射漏气信号，此时活塞杆3位于导电位；当导电环41和弹性触指42分离时，无线发射端的电路断开，不发出漏气信号，此时活塞杆3位于断电位。
在使用时，无线接收端可布置在车内。无线接收端包括接收盒6，接收盒6上设置有复位键63和充电口64，复位键63用于关闭以及开启无线接收端，同时在报警后按压复位键63可实现报警复位。充电口64用于与外界电源来通，对无线接收端充电。
报警设备为声光设备，声光设备包括指示灯61以及蜂鸣器，接收盒6的盒体上与蜂鸣器对应的位置处开设有蜂鸣孔62。在接收盒6通过内置的天线检测到无线发射端发出的无线信号时，无线接收端向报警设备发出报警信息，指示灯61亮起，蜂鸣器发出报警声音，一旦无线接收端开始报警，就一直保持报警状态(即使发射端不发出信 号，接收端依然保持报警状态)，直至人工按动接收端上的复位键63。
吸盘本体1的顶部设置有用于放置电路板5的放置腔11，放置腔11呈圆形，吸盘本体1上还通过螺钉固定有用于覆盖在放置腔11上的顶盖7，吸盘本体1上绕放置腔11一体成型有环形的凸起12，凸起12的横截面呈半圆形。电路板5上设置有外翻沿，外翻沿翻折在凸起12上，在顶盖7与吸盘本体1连接时，顶盖7通过电路板5的外翻沿挤压凸起12，增强了放置腔11的密封性，实现防水功能；在其他实施例中，也可以省略凸起12。
顶盖7上开设有成对布置的安装孔71，成对的安装孔71沿顶盖7的径向对称布置，安装孔71用于将吸盘安装在行李架上。安装孔71有多对，多对安装孔71绕顶盖7的中心线均匀分布，在本实施例中，安装孔71有四对，在其他实施例中，安装孔71也可以有两对、三对等，也可以仅有一对。根据车辆的车顶形式的不同，吸盘可以选择不同的安装孔71与行李架连接，增加了吸盘安装的角度。
上述的具有报警功能的吸盘在使用时，将吸盘固定在车顶上，当吸盘本体1的内腔出现漏气时，外壳2与密封皮碗32之间的负压腔22的压力减小，在弹簧35的弹力的作用下，活塞杆3弹出外壳2，杆帽33上的导电环41随活塞杆3移动，当导电环41与弹性触指42接触时，无线发射端的电池52的正负极导电连通，无线发射端通电，控制芯片53控制天线54向外发射漏气信号；无线接收端接收到天线54发射的信号时，指示灯61亮起，同时蜂鸣器发生蜂鸣声进行报警，直至人为按动无线接收端上的复位键63。
本发明的具有报警功能的吸盘的实施例2，如图12至图13所示，与实施例1的区别在于，触发电极包括布置在安装槽内的导电球44和顶压装配在导电球44与安装槽的槽底之间的压簧43，压簧43向外推动导电球44以增加触发电极与导电环41之间的接触力。
本发明的具有报警功能的吸盘的实施例3，与实施例1的区别在 于，行程开关为可径向活动的装配在外壳上的挤压块，挤压块上设置有导电连通的两个触点，活塞杆上布置有弧形环台，弧形环台随活塞杆移动时顶推挤压块以使挤压块径向活动，挤压块径向活动时其上的两个触点与电路板上的电极连通，活塞杆处于导电位，报警系统进行报警；弧形环台脱离挤压块时挤压块的触点与电路板上的电极断开，活塞杆处于断电位。
本发明的具有报警功能的吸盘的实施例4，与实施例1的区别在于，导电件也可以为径向嵌设在活塞杆内的导电杆，导电杆的轴向两端可分别与弹性触指接触以实现导电。
本发明的具有报警功能的吸盘的实施例5，与实施例1的区别在于，报警系统也可以为有线系统，有线系统包括电池和与电池通过线路连接的蜂鸣器，线路在弹性触指处形成断口。
本发明的具有报警功能的吸盘的其他实施例中，无线发射端与无线接收端也可以均设置蓝牙模块，无线发射端与无线接收端通过蓝牙模块传输信号；声光设备仅设置信号灯或者蜂鸣器中的一种以进行报警；报警设备也可以为语音设备，语音设备包括喇叭，喇叭内置有“吸盘漏气”等报警语句；报警设备也可以为震动设备，震动设备包括与无线接收端信号连接的震动器，通过震动器的震动引起操作人员的注意进行报警。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
