The follow-up contact device 1 serves as a collision structure with a vehicle when the tram is in operation. The vehicle detection device 2 is mounted on the head of the tramcar and is used for detecting the position of the surrounding vehicle, and the vehicle detection device 2 can be a plurality of distance sensors, radars and the like which are uniformly distributed at the front end of the tramcar. The driving device 3 is used for driving the follower contact device 1 to rotate, and for realizing precise control, a rotating oil cylinder is usually adopted, but other driving devices 3 playing the same role are also feasible, such as: a servo motor.
The follow-up contact device 1 comprises a collision frame arranged at the lower part of the front end of the tramcar, a covering layer covering the collision frame and a buffer mechanism arranged at the rear side of the collision frame. The covering is not shown in the figures because of its relatively simple construction and as a component of the trim panel. As shown in fig. 2 and 3, the buffer mechanism comprises a mounting seat 4 fixedly connected with the tramcar frame, a rotatable connecting block 5 arranged on the mounting seat 4 and a central buffer assembly. The central buffer assembly comprises a crumple type energy absorption tube 6 and a collision contact head 7, the collision contact head 7 is arranged right in front of the collision frame and is connected with one end of the crumple type energy absorption tube 6, the other end of the crumple type energy absorption tube 6 is fixedly connected with a connecting block 5, and the central buffer assembly is driven to adjust the direction through rotation of the connecting block 5. When collision happens, the collision contact head 7 and the collision frame are directly contacted with a vehicle, then the crumple type energy absorption tube 6 is extruded, the crumple type energy absorption tube 6 is crumpled and deformed, energy generated by collision can be effectively absorbed, the energy absorption effect is good, and personal safety of drivers and passengers is guaranteed.
The mounting seat 4 of the invention is used as a mounting base of the connecting block 5 and the central buffer component, and has more forms, such as: the mounting seat 4 comprises a vertical plate 13, two lug plates 14 arranged on one surface of the vertical plate 13 and parallel to each other, and a rear wing plate 15 arranged on the upper portion of the other surface of the vertical plate 13, and the connecting block 5 is positioned between the two lug plates 14 and hinged to the lug plates 14, so that the connecting block 5 can rotate. In order to improve the structural strength of the mounting seat 4, a triangular reinforcing plate 16 may be provided between the rear wing plate 15 and the upright plate 13. Of course, besides the above form, the mounting seat 4 can also be directly a cylinder, and the connecting block 5 is a sleeve body sleeved outside the mounting seat 4, so that the connecting block 5 is directly hinged by taking the cylinder as a hinge shaft, and the upper end and the lower end of the mounting seat 4 are fixedly connected with the frame. The outer surface of the sleeve body is provided with an external spline and is meshed with a gear through the external spline, and the gear is driven by a servo motor, a rotary oil cylinder and the like.
When the trolley bus is used, the vehicle detection device 2 detects the positions of other vehicles around the trolley bus in real time and feeds back the position information of the vehicles, the control system of the trolley bus judges collision directions in advance according to the position information and controls the driving device 3 to work, the driving device 3 drives the follow-up contact device 1 to adjust to the optimal contact position in real time, and even if collision occurs, accident loss can be greatly reduced. As shown in fig. 2 and 3, specifically, when the distance sensor detects that the distance between the vehicle in a certain direction is short, the distance is fed back to the control system of the tramcar, the control system sends a control signal to the rotary cylinder, the rotary cylinder acts to drive the connecting block 5 to rotate, and further the crumple type energy absorption tube 6 and the collision frame are driven to rotate to the corresponding direction. Therefore, when collision occurs, energy is effectively buffered, and the vehicle is protected.
In practice, the contact during collision is not usually a simple point contact, but a more complex surface contact, so in order to further improve the protection performance of the invention for the vehicle, it is better that the collision frame comprises a central collision frame 8 and corner collision frames 9 positioned at two sides of the central collision frame 8, and the edges of the central collision frame 8 and the corner collision frames 9 near the rear side are vertically hinged with each other. The buffer mechanism further comprises two groups of angle buffer assemblies positioned on two sides of the central buffer assembly, the central buffer assembly is opposite to the central collision frame 8, and the two angle buffer assemblies are respectively opposite to the two angle collision frames 9. The angle buffering component comprises a telescopic buffering rod 10, the two ends of the telescopic buffering rod 10 are hinged to the angle collision frame 9 and the connecting block 5 respectively, and generally, the two ends of the telescopic buffering rod 10 are hinged to the side faces of the angle collision frame 9 and the connecting block 5 through universal joints. When collision happens, the central collision frame 8 and the central buffer assembly are taken as main parts, and the angle collision frame 9 and the angle buffer assembly are taken as auxiliary parts to buffer energy together.
In order to further improve the energy absorption effect of the crumple type energy absorption tube 6 and maximize the effect of the crumple type energy absorption tube 6, the better way is that the middle section of the crumple type energy absorption tube 6 is also sleeved with a support ring 11, the support ring 11 is connected with the top of the central collision frame 8 through a pull rod 12, and the two ends of the pull rod 12 are respectively hinged with the side faces of the collision frame and the support ring 11. The support ring 11 is used for conducting collapse guiding on the collapse type energy absorption tube 6, so that the collapse direction is along the axial direction of the support ring, and the energy absorption effect of the collapse type energy absorption tube 6 is maximized.
In addition, when a collision occurs, the damage of the vehicle is directly related to the larger friction force between the vehicle and the ground besides the impact force directly influenced by the damage. For this purpose, it is better to form that the central collision frame 8 and the angle collision frame 9 are connected by a hollow rod, a plurality of electromagnets 20 connected in parallel are uniformly arranged inside the hollow rod, a pressure sensor 21 is arranged on the collision contact 7, and the electromagnets 20 are triggered by the pressure sensor 21. When the collision contact head 7 is in contact with the vehicle, the pressure sensor 21 detects a pressure signal and feeds the pressure signal back to the control system, and the control system controls the electromagnet 20 to be switched on, so that the vehicle is tightly adsorbed on the central collision frame 8 and the corner collision frame 9, the vehicle is directly separated from the ground or the friction force between the vehicle and the ground is reduced, and the damage to the vehicle is reduced. The electromagnet 20 is connected with the power supply in a parallel or independent wiring mode, so that the phenomenon of failure of the electromagnet 20 caused by circuit damage in the collision process can be prevented, and the working stability is improved.
