Fig. 1 shows the automatic driving vehicle or robot that anticollision device, collision-prevention device is equipped with according to the application one embodiment
Fragmentary perspective view.As shown in Figure 1, automatic driving vehicle or robot 100 may include shell 110 and chassis (not shown in figure 1),
Anticollision device, collision-prevention device 200 can be assemblied on chassis, to play anticollision work in the traveling process of automatic driving vehicle or robot 100
With.
Fig. 2 shows according to the application one embodiment for chassis anticollision device, collision-prevention device when not collided internal structure
Perspective view.As shown in Fig. 2, the anticollision device, collision-prevention device 200 for chassis 120 may include bottom plate 210, tension spring 220 and anticollision frame
230。
Bottom plate 210 is located at the end on chassis 120, so that fixation member of the bottom plate 210 as anticollision device, collision-prevention device 200.Example
Such as, can by welding, the end that bottom plate 210 is fixedly connected on chassis 120 by any mode appropriate such as rivet, be spirally connected, even
The end on bottom plate 210 and chassis 120 can also be integrally formed.
One end of tension spring 220 is connect with bottom plate 210, and the other end is connect with anticollision frame 230.For example, can be such as institute in Fig. 2
Show, one end of tension spring 220 can be connect and being articulated with tension spring bracket 211 with bottom plate 210, and the other end can be by being articulated with connection
Part 231 and be connected to anticollision frame 230, wherein tension spring bracket 211 and connector 231 are connected to bottom plate 210 and anticollision frame
Frame 230.Anticollision frame 230 is connected to bottom plate 210 by tension spring 220 as a result, so as to the movable part as anticollision device, collision-prevention device 200
Part.
Anticollision frame 230 can have collision prevention girders 232, and collision prevention girders 232 are located at the outside of 120 end of chassis.It is illustrated in fig. 2
It is state of the anticollision device, collision-prevention device 200 when not collided, the pulling force in tension spring 220 is 0 at this time.When encountering barrier, barrier
The power towards 120 direction of chassis can be applied to collision prevention girders 232, so that anticollision frame 230 be made to move towards the direction on chassis 120.
Since tension spring 220 is elongated with the movement of the one end being connected on anticollision frame 230, wherein being applied generating with barrier
The contrary pulling force of the impact force added, with Collision-free.
As a result, when barrier starts to contact so that collision prevention girders are subjected to displacement with collision prevention girders, it can be generated immediately in tension spring
Pulling force in contrast, with the increase of displacement, pulling force can also be increased with it, that is to say, that if the dynamics of collision is bigger, that
Generated opposite pulling force is also bigger in tension spring, to play preferable anti-collision effect.

Upward trigger board 240 is spaced scheduled distance with microswitch 250, and trigger board 240 is located at collision prevention girders 232 and microswitch
Between 250.That is, trigger board 240 does not connect with the driving piece of microswitch 250 when collision prevention girders 232 are not affected by collision
Touching.And when barrier collides collision prevention girders 232 so that anticollision frame 230 is whole mobile to 120 direction of chassis, trigger board 240 will
It is moved together with anticollision frame 230, and contacts the driving piece of microswitch 250, so that the movable contact of driving on piece is opened with fine motion
The fixed contact of pass is in contact, so that triggering microswitch issues electric signal, stops providing power with notification controller (not shown).
When certain displacement occurs after anticollision frame is collided as a result, microswitch can be triggered plate triggering, with hair
Electric signal out, to stop power supply, to avoid stronger collision or bigger damage occurs.
It is appreciated that trigger board may be provided at any position appropriate on anticollision frame, as long as can be with anticollision
Frame moves together, and is suitably set the position of microswitch, so that trigger board after being subjected to displacement, can trigger micro-
Dynamic switch issues electric signal.
According to one embodiment of the application, anticollision device, collision-prevention device 200 may include more tension springs 220, and first end can connect respectively
It is connected to the tension spring bracket 211 being arranged on bottom plate 210, second end can be connect by connector 231 with anticollision frame 230 respectively.Fig. 2
There are two tension springs 220 with embodiment shown in Fig. 3, it will be understood by those skilled in the art that can select according to actual needs
Number and the position of tension spring are selected, to obtain better anti-collision effect.Such as the setting of tension spring in Fig. 2 and Fig. 3, when barrier only collides
When the left side of collision prevention girders, pulling force mainly will be generated by the tension spring in left side；And when barrier only collides the right side of collision prevention girders, it will lead
Pulling force is generated by the tension spring on right side.
According to one embodiment of the application, anticollision frame 230 further includes C-shaped beam 233, C-shaped beam 233 in the horizontal plane with
Collision prevention girders 232 are fixedly connected.It is appreciated that C-shaped beam 233 and collision prevention girders 232 can be by the side appropriate such as welding, riveting, are spirally connected
Formula is fixedly connected, and is also possible to the two and is integrally formed.The second end of tension spring 220 is connected on C-shaped beam 233.Those skilled in the art
Member is it is appreciated that trigger board 240 may be disposed at the appropriate location of C-shaped beam 233, as long as enabling trigger board 240 with anticollision frame
Frame 230 moves together, and is suitably set the position of microswitch 250, so that trigger board 240 is after being subjected to displacement, energy
Enough triggering microswitches 250 issue electric signal.
According to one embodiment of the application, anticollision device, collision-prevention device 200 further includes more limited posts 260.Limited post 260 is fixed on
On bottom plate 210, and it is arranged adjacent to the inner or outer side of C-shaped beam 233.As shown in Figures 2 and 3, four of 233 outside of C-shaped beam
Limited post 260 is located at its two sides, can limit the movement in the horizontal direction of C-shaped beam so that C-shaped beam on perpendicular to Impact direction not
Over-large displacement can be generated.Two limited posts 260 of 233 inside of C-shaped beam can limit anticollision frame 230 to the fortune on the outside of the end of chassis
Dynamic, this also contributes to tension spring 220 in a relaxed state in correct posture.It will be understood by those skilled in the art that can be appropriate
Ground selects the position of limited post, to carry out limit appropriate to anticollision frame.
Further, at least part limited post in more limited posts 260 can have elastic sidewall.For example, can lead to
It crosses and resilient sleeve 261 is set and makes it have elastic sidewall (as shown in Figures 2 and 3) on the outer wall of limited post 260.Limited post
