Description

What have detecting obstacle function walks dust catcher certainly

Technical field

The utility model relevant for a kind of from walking dust catcher, be meant especially a kind of have a detecting obstacle function walk dust catcher certainly.

Background technology

Existing from walking dust catcher, include a body, one is located at the directive wheel of this body first half, be located at this body respectively and be positioned at the left lateral travelling wheel and the right lateral travelling wheel of this directive wheel rear and arranged on left and right sides, and several is located at the detecting system of this body leading edge.Existing when walking the dust catcher running, be to see through this directive wheel to control its direct of travel, and see through this left and right road wheel and advance or retreat, when aforementioned when walking dust catcher and advance, can in traveling process, detect its surface that is about to process through the obstacle detection sensor of these detecting systems and whether have obstacle, Gao Du drop for example, when detecting the place ahead when obstacle is arranged, one of them of this left and right road wheel can maintain static, and another road wheel can be drawn back, so as to changing from walking the direct of travel of dust catcher to avoid obstacle.Yet, existingly be not provided with detecting system, so that when when walking dust catcher and retreat for avoiding the place ahead obstacle from the rear of walking dust catcher, often whether there is obstacle and makes oneself walk dust catcher to fall down stair or sink into and cheat in the hole because of detecting the rear.

Summary of the invention

In view of this, it is a kind of when walking dust catcher certainly and retreat that main purpose of the present utility model is to provide, can detect the rear whether have obstacle have a detecting obstacle function walk dust catcher certainly.

For reaching above-mentioned purpose, provided by the utility model a kind of have a detecting obstacle function walk dust catcher certainly, mainly include a body; One first and second road wheel is located at this body accordingly, and the wheel axle extension line of this first and second road wheel is distinguished a first half and latter half of with this body; At least one obstacle detection sensor that is positioned at this body first half.Of the present utility modelly be characterised in that and also include at least one latter half of obstacle detection sensor of this body that is positioned at from walking dust catcher.Be provided with detecting system owing to the utlity model has the rear of walking dust catcher certainly of detecting obstacle function, therefore when walking dust catcher certainly and retreat, can detect its rear and whether have obstacle, avoid falling down stair or sinking into and cheat in the hole from walking dust catcher.

Have the walking certainly in the dust catcher of detecting obstacle function provided by the utility model, this at least one latter half of obstacle detection sensor of this body that is positioned at can be positioned at the latter half of edge of this body, to position that should the first road wheel rear side; Or be positioned at the latter half of edge of this body, to position that should the second road wheel rear side.Or the utility model can include two and is positioned at this latter half of obstacle detection sensor of this body from walking dust catcher, lays respectively at the latter half of edge of this body, to position that should first and second road wheel rear side.

The relevant detailed construction of walking dust catcher certainly and feature thereof with detecting obstacle function provided by the utility model below will be enumerated embodiment and conjunction with figs. illustrates it.

Description of drawings

Fig. 1 is a top perspective view, show according to the utility model one preferred embodiment do have a detecting obstacle function walk dust catcher certainly;

Fig. 2 is a stereogram of bottom view, show according to this preferred embodiment of the utility model do have a detecting obstacle function walk dust catcher certainly; And

Fig. 3 looks schematic diagram for the end of Fig. 1, shows that the obstacle detection sensor is positioned at the aspect at the latter half of edge of body.

The specific embodiment

In order to describe structure of the present utility model and characteristics place in detail, lift explanation of following preferred embodiment and conjunction with figs. as back now:

Please refer to Fig. 1 to Fig. 3, the utility model one preferred embodiment is provided have a detecting obstacle function walk dust catcher 10 certainly, mainly include a body 20, one first road wheel 30, one second road wheel 40 and two sensors 50.

This body 20 generally is oblate column, has the function of moving on a surface, for example at ground motion.This body 20 is by a plastic casing and be arranged at its inner power set and control circuit is constituted, because aforementioned power set belong to prior art and non-this case emphasis with control circuit, so holds the applicant and does not give unnecessary details at this.

This first road wheel 30 and second road wheel 40 are arranged at this body 20 accordingly, and the wheel axle extension line (L) of this first and

second road wheel

30,40 is divided into a first half 21 and one latter half of 23 with this body 20.The first half 21 of this body 20 is provided with a directive wheel 211, can rotate by 360 degree, in order to control the direct of travel of this body 20.In addition, an edge of this body first half 21 equidistantly is laid with three obstacle detection sensors 213 in order to detecting the place ahead obstacle, because this directive wheel 211 and this obstacle detection sensor 213 also belong to known technology, does not therefore give unnecessary details.

Of the present utility model focusing on: this two obstacles detection sensor 50, identical with the action principle of aforementioned obstacles detection sensor 213 in the present embodiment, also for seeing through optical transmitting set, have or not with optical receiver again to receive reverberation and judge whether running-surface is smooth towards the running-surface irradiates light.About the detailed action principle of obstacle detection sensor 50, please refer to applicant application the novel patent of TaiWan, China application M294508 number.One of them of this two obstacles detection sensor 50, as shown in Figure 2, be arranged at an edge of this body latter half of 23, to position that should second road wheel, 40 oblique rears, and contiguous this second road wheel 40, another of this two obstacles detection sensor 50 then is arranged at the edge of this body latter half of 23, to position that should first road wheel, 30 oblique rears, and contiguous this first road wheel 30.Whereby, when when walking dust catcher 10 and retreat, can see through obstacle detection sensor 50 its rears of detecting that are arranged at this body latter half of 23 and whether have obstacle for avoiding the place ahead obstacle.

What deserves to be mentioned is, the quantity of this obstacle detection sensor 50 is not limited to two, visual actual demand and changing, for example only has this obstacle detection sensor 50, and can be arranged at an edge of this body latter half of 23 on demand, to position that should first or second road wheel, 30,40 oblique rears, and contiguous this first or

second road wheel

30,40.

During actual operation, when walking dust catcher 10 certainly when mobile forward, whether these obstacle detection sensors 213 that are arranged in these body first half 21 edges can have obstacle on its surface that is about to process of traveling process detecting, Gao Du drop for example, when detecting the place ahead when obstacle is arranged, this first and second road wheel 30, one of them of 40 can maintain static, and another road wheel can be drawn back, and change from walking the direct of travel of dust catcher 10 to avoid obstacle by this directive wheel 211, when walking dust catcher 10 certainly when mobile backwards, the obstacle detection sensor 50 that is arranged at this body latter half of 23 can be detected its rear and whether have obstacle, and dust catcher 10 continues to retreat or carry out go to action again from walking in control according to this.

To sum up institute is old and since the utlity model has detecting obstacle function walk dust catcher certainly, the latter half of obstacle detection sensor that can detect obstacle that also is provided with of its body, thereby can avoid from walking to fall down stair when dust catcher retreats or sinking into to cheat in the hole.
