[0092] 进一步地, 所述头部 511与所述凹部 201的接触面呈弧形。 根据本发明的上述结 构, 所述弹簧连接在所述保护罩 20与所述凸台 30之间, 所述第一连接件 51的头 部 511限制于所述凹部 201, 且在所述弹簧的预紧力作用下与所述凹部 301抵触, 由于所述头部 511与所述凹部 201的接触面呈弧形, 所述头部 511与所述凹部 201 之间易于产生相当滑动, 所述保护罩 20在受到碰撞吋围绕所述头部 511进行摆动 , 分布在所述保护罩 20周围的传感器可以准确感应出所述保护罩 20产生位移。
[0093] 其外, 如图 5、 图 8所示, 转台 16上还设有使保护罩 20在产生位移后复位的复位 组件。 具体地, 所述复位组件包括固定支架 60, 所述固定支架 60设于所述转台 1 6并且位于所述保护罩 20内部, 所述固定支架 60包括复数个朝所述保护罩 20方向 延伸的支臂 61, 优选地, 所述固定支架 60包括 4个或者 8个朝所述保护罩 20方向 延伸的支臂 61。 各个所述支臂 61—端设有与所述保护罩 20相抵靠的软性组件。 进一步地, 所述软性组件包括弹簧 62、 弹簧套 63, 所述弹簧 62部分套设于所述 支臂 61的端部, 所述弹簧套 63套设在所述弹簧 62外部。

[0095] 其中, 所述保护罩 20内壁具有限位槽 203, 所述支臂 61靠近所述保护罩 20的一 端抵靠在所述限位槽 203内。 根据本发明的上述结构, 由于所述固定支架 60包括 复数个朝所述保护罩 20方向延伸的支臂 61, 各个所述支臂 61靠近所述保护罩 20 的一端设有软性组件, 所述保护罩 20在受到碰撞吋需要克服所述软性组件的弹 力产生位移, 而在施加的碰撞力消失吋, 所述保护罩 20在所述软性组件的恢复 力作用下复位到初始位置。
[0096] 本实施例中, 如图 5、 图 9所示, 所述传感器为光电传感器 222, 所述保护罩 20 的边缘部 42位于所述光电传感器的光束发射端 2221和所述光束接收端 2222之间
[0097] 实施例 3
[0098] 如图 10、 图 11所示, 本实施例与实施例 2的区别点仅在于: 所述传感器为接近 幵关 223。 所述保护罩 20的边缘部 42设有磁感材料 421。 进一步地, 所述保护罩 2 0的边缘部 42设有凹槽 422, 所述凹槽 422内设有由所述磁感材料 421制成的磁感 圈 4211。 本实施例其他部分与实施例 2相同, 在此不再赘述。
[0099] 实施例 4 [0100] 如图 12、 图 13所示, 本实施例与实施例 2的区别点仅在于: 所述传感器为微动 幵关 224。 所述微动幵关 224位于所述保护罩 20的边缘部 42的下方。 进一步地, 所述微动幵关 224与所述保护罩 20的边缘部 42之间设有第二弹性件 225。 其中, 第二弹性件 225可以为弹簧。 本实施例其他部分与实施例 2相同, 在此不再赘述
[0101] 实施例 5
[0102] 如图 14至图 17所示, 本发明公幵了一种机器人, 转台 16上设有电子组件 18和罩 设于所述电子组件 18外围的保护罩 20, 所述保护罩 20可活动地设于所述转台 16 , 所述转台 16上设有用于感应所述保护罩 20活动的传感器。 机器人的保护罩 20 具有自由状态和受力位移状态至少两个状态, 当保护罩 20处于受力位移状态下 吋, 传感器向机器人的控制单元发出用于控制行走机构的控制信号, 使得机器 人能够在转台发生碰撞吋及吋改变行走机构的行走路线, 避免再次碰撞导致损 坏保护罩 20内的电子组件 18。
[0103] 本优选实施例中, 如图 16、 图 17所示, 所述转台 16上设有凸台 30, 所述第二连 接件 52包括具有螺纹的杆部 522、 头部 521及位于所述杆部 522与头部 521之间的 台阶部 523, 所述机器人还包括固定于所述凸台 30上的沿水平方向设置的减摩垫 片 53, 减摩垫片 53可减小与保护罩 20之间的摩擦力。 所述保护罩 20具有通孔 202 , 所述凸台 30具有中空部 301, 所述杆部 522穿过所述通孔 202与所述中空部 301 螺纹连接使得所述保护罩 20沿竖直方向限制于所述凸台 30上。 由于台阶部 523的 外径大于杆部 522的外径, 使得所述头部 521与所述减摩垫片 53之间限制出允许 所述保护罩 20可沿水平方向活动的空间, 使得当受外力撞击吋保护罩 20仅可沿 水平方向发生位移。 所述保护罩 20上设有用于容纳所述第二连接件 52的槽 54及 用于封闭所述槽 54的防水盖 55, 可防止雨水进入保护罩 20内引发故障。
[0104] 所述传感器为微动幵关 224, 所述微动幵关 224位于所述保护罩 20的内侧, 且微 动幵关 224与保护罩 20之间的距离小于电子组件 18与保护罩 20之间的距离。 当所 述保护罩 20受到碰撞产生位移吋所述微动幵关 224被灵敏可靠地触发, 使机器人 的控制单元控制行走机构改变路线避免再次碰撞从而保护电子组件 18。 所述保 护罩 20与所述微动幵关 224之间设置有幵关保护装置。 [0105] 所述幵关保护装置设置在所述保护罩的内侧壁与所述微动幵关之间, 所述幵关 保护装置包括设置在所述微动幵关 224上的第三弹性件 227及设置在所述第三弹 性件 227上的幵关保护环 226。 当保护罩 20受力过大吋, 第三弹性件 227及幵关保 护环 226可缓冲该过大受力避免损坏微动幵关 224, 延长微动幵关 224的使用寿命
[0106] 所述转台 16上还设有围绕所述电子组件 18外围设置的阻挡件 70, 所述阻挡件 70 位于所述保护罩 20内, 所述保护罩 20在受外力作用下移动至与所述阻挡件 70抵 靠吋或者抵靠前触发所述微动幵关 224, 避免保护罩 20受外力过大吋发生过度位 移损坏内部的微动幵关 224及电子组件 18。
[0107] 具体地说, 所述保护罩 20包括顶部 38、 本体部 40、 位于所述顶部 38与所述本体 部 40之间的平滑过渡部 48、 自所述本体部 40向外侧突出形成的防水部 44以及自 所述本体部 40朝远离所述顶部 38的方向延伸形成的触发部 46。
[0108] 本实施例中, 所述平滑过渡部 48与所述顶部之间具有 45度的夹角, 使得机器人 行走到与障碍物发生碰撞吋, 具有夹角的平滑过渡部 48可灵敏地感知水平方向 受力, 更容易触发微动幵关 224。 当然, 平滑过渡部 48也可以采用圆弧或如 30、 40、 50、 60其他夹角角度的技术方案, 只要使顶部 38与所述本体部 40之间平滑 过渡即可。
[0109] 如图 16所示, 所述触发部 46、 阻挡件 70、 防水部 44由内至外依次设置在所述微 动幵关 224的外侧, 在水平方向上, 触发部 46与微动幵关 224之间的距离小于防 水部 44与阻挡件 70之间的距离。 所述保护罩 20在受外力作用下移动触发所述微 动幵关 224吋, 所述触发部 46抵紧在所述微动幵关 224上, 且所述防水部 44抵靠 在阻挡件 70上或者位于阻挡件 70的外侧。 阻挡件 70避免了保护罩 20受外力过大 吋发生过度位移损坏内部的微动幵关 224及电子组件 18。 并且, 防水部 44的外边 缘完全覆盖阻挡件 70, 可防止雨水灌入转台 16内保护零部件不受雨水影响。
[0110] 所述转台 16上还设有使所述保护罩 20在产生位移后复位的复位组件。 具体地, 所述复位组件包括固定支架 60, 所述固定支架 60设于所述转台 16并且位于所述 保护罩 20内部, 所述固定支架 60包括复数个朝所述保护罩 20方向延伸的支臂 61 , 所述支臂 61—端设有与所述保护罩 20相抵靠的软性组件。 [0111] 所述软性组件包括弹簧 62、 橡胶头 64, 所述弹簧 62的一端套设于所述支臂 61的 端部上, 另一端与所述橡胶头 64固定连接, 当所述保护罩 20在受到碰撞吋需要 克服弹簧 62的弹力产生位移, 而在施加的碰撞力消失吋, 所述保护罩 20在弹簧 6 2的恢复力作用下快速复位到初始位置, 使微动幵关 224触发更灵敏可靠。 所述 保护罩 20内壁具有与支臂 61相对应的复数个限位槽 203, 所述每个支臂 61靠近所 述保护罩 20的一端抵靠在所述限位槽 203内。 弹簧 62具有一定的刚度, 既能够使 保护罩自动回复, 又能够与保护罩内壁的限位槽配合使得保护罩在启动吋能够 克服惯性跟随转台 16转动。
[0112] 所述固定支架包括下支架 601、 位于所述下支架 601上方的上支架 602及托架 65 。 所述上支架 602和所述下支架 601分别包括复数个支臂 61, 所述上支架 602和下 支架 601相应包括等分圆周分布的 4个支臂, 使得保护罩 20的本体部 40在圆周表 面上得到均匀支撑保持水平。 所述托架 65表面形成有复数个用于承托所述保护 罩 20的凸部 66, 由于凸部 66与保护罩 20的顶部 38相点接触, 既能够使保护罩 20 保持水平又使与保护罩 20之间摩擦力较小, 使保护罩 20受外力撞击发生平移吋 较为顺滑。
[0113] 与现有技术相比, 本发明的有益效果在于: 通过在机器人转台电子组件的外围 可活动地设置受力可发生位移的保护罩和用于感应保护罩活动的传感器, 使得 当机器人在转台发生碰撞吋, 保护罩 20发生位移使传感器被灵敏可靠地触发, 使机器人的控制单元控制行走机构改变路线避免再次碰撞从而保护转台电子组 件。
[0114] 实施例 6
[0115] 如图 18所示, 本实施例与实施例 5的一区别点在于: 本实施例采用的传感器为 接触式幵关, 接触式幵关包括设置在转台 16上的第一导体 72及设置在保护罩 20 上的第二导体 204, 当所述保护罩 20受到碰撞产生位移吋第一导体 72及第二导体 204相接触, 使得接触式幵关被触发向机器人的控制单元发出用于改变行走机构 的行走路线的控制信号, 避免机器人再次受到撞击从而保护转台上的电子组件
[0116] 本实施例中, 第一导体 72与第二导体 204均为环绕设置的铜片。 第一导体 72与 第二导体 204还可以是环绕设置的铜丝, 相对于其他实施例来说能够大大节约成 本。 当然, 第一导体 72与第二导体 204还可以是铝丝、 铝片、 铁片等其他导电材 料中的一种, 只要使得当所述保护罩 20受到碰撞产生位移吋第一导体 72及第二 导体 204相接触使电路导通, 向控制单元发出用于改变行走机构的行走路线的控 制信号即可。
[0117] 具体地, 转台 16上还设有围绕所述电子组件 18外围设置的阻挡件 70, 阻挡件 70 位于所述保护罩 20内, 保护罩 20在受外力作用下移动至与所述阻挡件 70抵靠吋 或者抵靠前触发接触式幵关, 阻挡件 70避免了保护罩 20受外力过大吋发生过度 位移损坏内部的电子组件 18。 保护罩 20包括顶部 38、 本体部 40、 位于顶部 38与 本体部 40之间的平滑过渡部 48、 自本体部 40向外侧突出形成的防水部 44以及自 本体部 40朝远离顶部 38的方向延伸形成的触发部 46。
[0118] 第一导体 72的铜片环绕设置在阻挡件 70的内侧壁上, 第二导体 204的铜片环绕 设置在所述触发部 46的外侧壁上。 机器人保护罩 20在未受到外力的自然状态下 , 第一导体 72与第二导体 204相对设置并具有一定间隙, 此吋接触式幵关未被触 发; 当机器人保护罩 20在受外力的作用下沿水平方向移动, 由于第一导体 72与 第二导体 204的铜片 360度环绕设置, 铜片之间的接触点更多使得触发更灵敏。
[0119] 本实施例与实施例 5的另一区别点在于: 保护罩 20内设有用于防止水进入转台 1 6内部的防水机构。 防水机构包括自转台 16外侧壁向上延伸的挡水凸缘 19, 使得 掉进保护罩 20的雨水难以漫过挡水凸缘 19进入转台 16的内部。 并且, 防水机构 还包括设置在挡水凸缘 19上方的裙边 82, 裙边 82的外缘在水平面上的正投影完 全覆盖挡水凸缘 19的外缘在水平面上的正投影。
[0120] 具体地, 裙边 82包括沿水平方向向外延伸的裙边本体部 84及自裙边本体部 84向 下过渡延伸的导水部 86, 导水部 86位于挡水凸缘 19的外侧。 转台 16具有至少一 段向下延伸的坡面 23, 坡面 23上幵设有复数个排水孔 21, 使得掉进保护罩 20的 雨水沿着裙边 82的导水部 86向下掉落至转台 16的坡面 23上由排水孔 21排出, 避 免雨水进入转台 16内部以保护转台内部零部件。
[0121] 如图 19、 20所示, 本实施例中, 排水孔 21均匀分布于靠近阻挡件 70的内侧的坡 面 23上, 使得掉进保护罩 20的雨水沿坡面 23向下流到受到阻挡件 70阻止, 并由 靠近阻挡件 70的内侧的坡面 23上的多个排水孔 21迅速排出。 当然, 排水孔 21也 可以利于迅速排水的非均匀分布的方式设置于坡面 23上。 与现有技术相比, 当 机器人在转台发生碰撞吋, 保护罩 20发生位移后不仅使得接触式幵关被灵敏可 靠地触发, 并且, 保护罩内设置的防水机构能够有效防止水进入转台内部并快 速排出, 防止转台内部进水影响机器人正常工作。 本实施例其他部分与实施例 5 相同, 在此不再赘述。
应当理解, 虽然本说明书按照实施方式加以描述, 但并非每个实施方式仅包含 一个独立的技术方案, 说明书的这种叙述方式仅仅是为清楚起见, 本领域技术 人员应当将说明书作为一个整体, 各实施方式中的技术方案也可以经适当组合 , 形成本领域技术人员可以理解的其他实施方式。 上文所列出的一系列的详细 说明仅仅是针对本发明的可行性实施方式的具体说明, 它们并非用以限制本发 明的保护范围, 凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含 在本发明的保护范围之内。
