It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.
Referring to fig. 1-2, an embodiment of the present utility model provides a vehicle anti-collision device configured on a vehicle body of a vehicle to prevent the vehicle from colliding with a person standing on a vehicle track and other vehicles adjacent to the person. The driving anti-collision device comprises a mounting part 100 and a touch assembly 200, wherein the driving anti-collision device is mounted on a driving body through the mounting part 100, and the driving anti-collision device is touched with personnel and other adjacent driving through the touch assembly. The touch assembly 200 includes a connection rod 210, a touch plate 220, and an elastic protection member 230, wherein one end of the connection rod 210 is disposed on the mounting portion 100, and the other end is fixedly connected with the touch plate 220. In the axial direction along the connecting rod 210, the projected area of the touch plate 220 is larger than the projected area of the connecting rod 210, and the projection of the touch plate 220 covers the projection of the connecting rod 210, and the elastic protection member 230 is disposed on the side of the touch plate 220 away from the connecting rod 210.
In this embodiment, the anti-collision protection range of the anti-collision device of the vehicle is positively correlated with the projection area of the touch plate 220 in the axial direction along the connecting rod 210, and since the projection area of the touch plate 220 is larger than the projection area of the connecting rod 210 and the projection thereof covers the projection of the connecting rod 210, compared with the feeler lever of the prior art, the touch plate 220 increases the anti-collision protection range of the anti-collision device of the vehicle, and the vehicle has better anti-collision protection effect on the person standing on the track of the vehicle and the adjacent vehicle. Meanwhile, the elastic protection piece 230 is arranged on the touch plate 220, so that the elastic protection piece 230 forms buffer protection for collision of people in collision contact with the touch plate or adjacent travelling crane, and pain caused by collision contact between the anti-collision device and the people is remarkably reduced. It should be appreciated that the resilient guard 230 deforms when squeezed by a person or an adjacent row of vehicles and urges the touch assembly 200 toward the mounting portion 100.

The mounting portion 100 has a mounting groove 110 extending along a traveling direction of the vehicle, and one end of the connecting rod 210 is movably inserted into the mounting groove 110 and slides back and forth along the traveling direction of the vehicle. The outer surface of the connecting rod 210 is provided with a guide protrusion 211, the groove wall of the mounting groove 110 is provided with a guide groove 120, and the guide protrusion 211 extends into the guide groove 120 and is in sliding fit with the guide groove 120. The guide groove 120 and the notch of the mounting groove 110 have a distance therebetween to prevent the connection rod 210 from exiting the mounting groove 110. A first spring 230 is installed in the installation groove 110, and the first spring 230 is located at a side of the connection bar 210 away from the touch panel 220 and is in abutting engagement with the connection bar 210 to provide an elastic force for a restoring movement to the connection bar 210. The touch preventing device further comprises a limit switch 300, the limit switch 300 is arranged on the mounting portion 100, a contact of the limit switch 300 is located on one side, close to the mounting portion 100, of the touch plate 220, and the limit switch 300 is connected with a controller of the driving body. The touch module 200 has an initial position in which the guide protrusion 211 and the guide groove 120 are in stop engagement near the groove wall of the touch panel 220, and the contact point of the touch module 200 is disposed proximate to the touch panel 220. When the touch module 200 is touched, the touch module 200 is moved toward the mounting portion 100 to trigger the limit switch 300. After the limit switch 300 is triggered, the controller of the driving body controls the driving to stop, and after the touch assembly 200 is separated from the person or the driving touched by the driving body, the touch assembly 200 is reset under the driving of the first spring 230.
Wherein, the peripheral side wall of the connecting rod 210 is provided with a receiving groove, the receiving groove is provided with a second spring 240, and the guiding protrusion 211 is movably inserted into the receiving groove and is supported by the second spring 240.
In some embodiments of the present utility model, the elastic protection member 230 includes an annular first connection portion 231 and a buffer portion 232, the first connection portion 231 is connected to the touch panel 220 in a sealing manner, the first connection portion 231 is located at an outer Zhou Judi of the buffer portion 232, an inner diameter end of the connection portion 231 is connected to the buffer portion 232 in a sealing manner, the buffer portion 232 protrudes in a direction away from the touch panel 220, and a sealed air storage cavity 233 is formed between the buffer portion 232 and the touch panel 220.
In the present embodiment, the elastic protection member 230 is mainly protected by the buffer portion 232. Because the buffer portion 232 protrudes out of the first connecting portion 231 and forms the air storage cavity 233 with the touch panel 220, the buffer portion 232 has a relatively large elastic buffer distance, so that pain injury to personnel when the touch panel 220 touches the personnel can be further reduced, and the protection effect of the anti-collision device on the personnel and the travelling crane is further improved.
The first connection portion 231 and the touch plate 220 may be bonded by using a sealant, so as to realize a sealing connection between the first connection portion 231 and the touch plate 220. The first connection portion 231 and the buffer portion 232 are integrally formed, so that the elastic protection member 230 has better overall sealability and structural strength.

By providing the annular airbag 400, when the touch module 200 touches a person or a car, not only the touch module 200 moves toward the mounting portion 100 and the annular airbag 400 expands toward the contact of the limit switch 300, the time for triggering the touch module 200 is reduced, the triggering speed of the limit switch 300 is increased, and the sensitivity of the anti-collision device is improved.
The annular airbag 400 includes an annular second connecting portion 410, an airbag main body portion 420, and an annular third connecting portion 430, which are sequentially connected, and the second connecting portion 410 and the third connecting portion 430 are hermetically connected to the touch panel 220.

The elastic protection member 230 and the annular airbag 400 may be made of rubber or silica gel. The elastic protection member 230 has an elastic coefficient lower than that of the annular air bag 400. In other embodiments, the elastic protection member 230 and the annular air bag 400 may be made of the same material, and the thickness of the elastic protection member 230 is greater than that of the annular air bag 400.
In some embodiments of the present utility model, the touch plate 220 is provided with an air injection hole, one end of which extends to the air storage cavity 233 and the other end extends to the outer circumferential surface of the touch plate 220, and an air inlet of the air injection hole is provided with a sealing plug 221.
