Description

Automatic driving tractor

Technical Field

The utility model belongs to the technical field of car intelligent driving, concretely relates to automatic drive tractor.

Background

The automatic driving prospect is wide, and related research is in the spotlight. At present, the automatic driving technology has been widely applied in the freight transportation direction, and various automatic driving trucks, automatic driving tractors and the like emerge. In order to improve the safety of the autonomous vehicle, many detection sensors, cameras, etc. are usually designed to avoid collision and accident. However, in areas with many high shelves in the warehouse, the vision is obstructed, the walking situation of personnel is complicated, the turn light of the tractor is blocked by the trailer, and the situations that the rear personnel and the vehicle cannot judge are caused, so how to further improve the safety is a technical problem to be solved urgently at present.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a warn through sound, characters, light etc. to improve the autopilot tractor of security.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an automatic drive tractor, includes the automobile body, set up one on the automobile body and be used for outwards carrying out the sound warning device of sound warning to tractor driving state, tractor driving state includes: starting, braking, steering, parking and backing; the sound warning device comprises at least one loudspeaker arranged outside the vehicle body.

Preferably, an LED screen for displaying the running state of the tractor through characters is arranged at the position on the rear upper side of the tractor body.

Preferably, the sound warning device is two loudspeakers arranged at two ends of the LED screen.

Preferably, the tractor driving state further includes: butt-jointing with the trailer and unhooking the trailer.

Preferably, the vehicle further comprises a warning lamp arranged on the vehicle body.

Preferably, the vehicle body further comprises a sensor for detecting whether an obstacle exists in front of the vehicle body, and the sensor is electrically connected with the sound warning device.

Preferably, the rear part of the vehicle body is provided with a traction base connected with a trailer.

The utility model has the advantages that: the running state of the automatic driving tractor is broadcasted through sound, an LED screen, a warning lamp and the like, pedestrians around the warning are warned to avoid, and the automatic driving tractor can also be used for reminding workers to timely carry out loading, unloading and other operations, so that the safety and the convenience are greatly improved.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the automatic driving tractor of the present invention comprises a tractor body 2, wherein an LED screen 4 for displaying the running state of the tractor through characters is arranged at the upper position behind the tractor body 2; two ends of the LED screen 4 are respectively provided with a loudspeaker 6 as a sound warning device.

The automobile warning device further comprises a warning lamp 8 arranged on the automobile body 2 and a sensor 10 used for detecting whether an obstacle exists in front of the automobile body 2, wherein the sensor 10 is electrically connected with the sound warning device.

The tractor driving state comprises the following steps: starting, braking, steering, parking, backing and trailer butt joint, trailer unhooking and the like. The parking includes the path point which reaches a certain middle path point and needs to load and unload goods. Once the driving state of the tractor is about to change, nearby workers are warned through the loudspeaker 6 and the LED screen 4 to carry out avoiding or loading and unloading operations. It sets up at the top, also conveniently reminds the rear vehicle, avoids being blockked the indicator by the trailer.

The condition that a voice warning device is arranged on a vehicle driven by a person is common and is usually used for reminding backing; similar structures are not found in unmanned vehicles at present; most sound warning devices only prompt reversing, and rarely prompt steering instead of the driving states of the tractor such as starting, braking, steering, parking, reversing, trailer butt joint, trailer unhooking and the like prompted by the invention; particularly, the prompt is used for butting with the trailer and unhooking with the trailer, so that nearby workers can be reminded of loading and unloading the trailer in time.

Further, a traction base 12 connected with the trailer is arranged at the rear part of the vehicle body 2. The traction base 12 comprises a V-shaped guide groove 14, and a through pin hole 16 is vertically arranged at the bottom of the guide groove 14. A motor 18 drives a vertically arranged pin shaft 20 to move up and down along the pin hole 16 in a worm and gear mode, and the motor can be matched with a proximity sensor 22 arranged at the bottom of the guide groove to judge whether a traction rod 24 of a trailer 28 enters the guide groove 14 or not, and then the motor is automatically inserted into the pin hole 16 and a through hole 26 on the traction rod 24 through the pin shaft 20, so that the trailer can be automatically connected in a reverse mode of the towing vehicle. In the same way, the automatic unloading of the trailer can be realized.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
