The utility model relates to a road-finding tool for blind people to travel, i.e. a push-rod guide vehicle. It consists of a push rod with a horizontal roller rack at the touching end of the push rod, and two rollers arranged side by side between the roller racks. It is characterized by a cantilever at the front end of the roller rack, a blind guide roller connected by a wheel rack at the bottom of the front end of the cantilever, and a blind guide roller connected by a vertical shaft on the wheel rack and a cantilever. Set up the guide roller of blind path. If the deviation is carried out, the vertical arm of the contact point is connected with the upper contact point of the cantilever, and the alarm circuit is connected to warn the deviation from the blind path, it can be corrected and corrected in time. The outer end of the wing arm has a horizontal roller, which can roll in contact with the obstacles encountered, reduce resistance, and walk along with them, and send out warning sounds; the wing arm is connected with the roller frame, and there is room for maneuver when encountering obstacles. There is an ultrasonic induction probe on the roller rack, which can detect and alarm obstacles about two meters ahead in time so as to avoid them in time.
【技术实现步骤摘要】
推杆式导盲车
本技术涉及一种盲人出行使用的探路工具,即推杆式导盲车。
技术介绍
在现有技术中,盲人出行使用的探路工具通常为一个细木杆,行走中指指点点,其缺点是不安全,容易碰到其他行人,特别是小孩,造成双方都不安全。再就是费力劳累、行走慢。三是不能携带物品,功能单一,使用不便。
技术实现思路
本技术的目的是针对上述不足而提供一种推行警示功能多、结构更加合理,行动安全、使用方便的推杆式导盲车。本技术的技术解决方案是:推杆式导盲车,包括推杆,推杆触地端带有横向滚轮架,滚轮架上并排间隔有两个滚轮,其特征在于:滚轮架前端有悬臂,悬臂前端下面有通过轮架连接的盲道导向滚轮,盲道导向滚轮通过轮架上立轴与悬臂转动连接。上述方案中:滚轮架上有报警装置,报警装置触点设在悬臂上,盲道导向滚轮轮架侧面上有与悬臂上触点碰接的触点立臂。盲道导向滚轮前端有辅助滚轮,辅助滚轮通过辅助滚轮轮架与盲道导向滚轮轮架活动连接。悬臂与滚轮架活动铰接,悬臂与滚轮架上探出的固定臂之间连接有弹簧。盲道导向滚轮轮架与立轴下端通过转轴连接,盲道导向滚轮轮架与转轴有限转动,并通过弹簧对盲道导向滚轮轮架有向前推力作用连接。滚轮架至少一侧带探出的翼臂,翼臂外端有卧式滚轮。翼臂与滚轮架通过翼臂立轴活动连接,并通过翼臂弹簧对翼臂有向前推力作用连接。卧式滚轮上边缘有立凸柱,对应翼臂上有与立凸柱拨动的弹簧丝,弹簧丝一面有挡体。滚轮架上有超声波感应探头。推杆中下部可以固定有储物筐,出行、购物、携带东西更方便。本技术的优点是:1、设置盲道导向滚轮,如果推行偏移,触点立臂与与悬臂上触点碰接,接通报警电路,警示偏离盲道,可及时修正改回。2 ...
