Specific embodiment
A kind of tramcar and vehicle anticollision active protective device in conjunction with shown in Fig. 1-3, including setting is in rail electricity
For buffering servo-actuated contact device 1, the motor vehicle detector 2 for detecting other vehicle headings, basis of collision energy on vehicle
The servo-actuated contact device 1 of vehicle location driving detected adjusts the driving device 3 in orientation.The servo-actuated contact device 1 is in rail
When electric car is run, as the crash feature with vehicle.The motor vehicle detector 2 is mounted on tramcar head, for detecting
Around vehicle location, the motor vehicle detector 2 can for multiple range sensors for being evenly distributed on tramcar front end,
Radar etc..The driving device 3, to realize accurate control, generallys use rotation oil for driving servo-actuated contact device 1 to rotate
Cylinder is also certainly feasible using other driving devices 3 for playing phase same-action, such as: servo motor.
The servo-actuated contact device 1 includes the collision frame that tramcar front lower portion is arranged in, covers to be located at and collide outside frame
Overlay and the buffer gear being arranged on rear side of collision frame.Since the structure of overlay is relatively simple, and as decoration panel portion
Part is not shown in figure.As shown in Figures 2 and 3, the buffer gear includes the mounting base 4 affixed with tramcar vehicle frame, sets
Set rotatable link block 5 and central buffer component in mounting base 4.The central buffer component includes collapse type energy absorbing tube
6 and making contact head 7, the making contact head 7 is arranged in the front of collision frame and connects with one end of collapse type energy absorbing tube 6
It connects, the other end and link block 5 of the collapse type energy absorbing tube 6 are affixed, are rotated by link block 5 and drive the adjustment of central buffer component
Direction.Collide occur when, making contact head 7 and collision frame directly and vehicle contact, then squeeze collapse type energy absorbing tube 6, routed
Crumple deformation occurs for contracting formula energy absorbing tube 6, can effectively absorb the energy that collision generates, and energy-absorbing effect is good, guarantees driver and passenger
Personal safety.
Installation foundation of the mounting base 4 of the present invention as link block 5 and central buffer component, form is more, such as:
The mounting base 4 includes that vertical plate 13, two to be parallel to each other the otic placode 14 that 13 one side of vertical plate is arranged in and setting are another in vertical plate 13
The rear fender 15 on top on one side, the link block 5 are located between two otic placodes 14 and constitute with otic placode 14 hingedly, thus the company of realization
Connecing block 5 can be rotated.In order to improve the structural strength of mounting base 4, three can also be arranged between the rear fender 15 and vertical plate 13
Angular stiffening plate 16.Certainly, in addition to above-mentioned form, mounting base 4 can also directly be exactly a cylindrical body, and link block 5 is exactly
One body being set in outside mounting base 4, thus directly using cylindrical body as articulated shaft that link block 5 is hinged, mounting base 4 it is upper
End and lower end and vehicle frame are affixed.External splines is arranged in the outer surface of body, and is engaged by external splines with gear, and gear is by servo electricity
The driving such as machine, rotary oil cylinder.
When in use, around 2 real-time detection tramcar of motor vehicle detector other vehicles position, and feed back vehicle
The control system of location information, tramcar prejudges collision bearing according to location information, and controls the work of driving device 3, driving
The servo-actuated contact device 1 of the driving of device 3 is adjusted to optimum contact position in real time, even if colliding, accident can also can be greatly reduced
Loss.As shown in Figures 2 and 3, specifically, that is, when range sensor detects that certain orientation vehicle distances is closer, feedback
To the control system of tramcar, control system sends control signal to rotary oil cylinder, and rotary oil cylinder movement drives link block 5
Rotation, and then collapse type energy absorbing tube 6 and collision frame is driven to rotate to corresponding orientation.To effectively delay when colliding
Energy is rushed, realizes the protection to vehicle.
In practice, contact when collision is not usually simple point contact, but increasingly complex face contact, because
, in order to further increase the present invention to the protective value of vehicle, better way is that the collision frame includes Central Collisions frame 8 for this
With the corner impact frame 9 for being located at 8 two sides of Central Collisions frame, the Central Collisions frame 8 and corner impact frame 9 are perpendicular close to the edge of rear side edge

Buffer Unit includes flexible buffer bar 10, and the both ends of the flexible buffer bar 10 are hinged with corner impact frame 9 and link block 5 respectively,
The both ends of the usual flexible buffer bar 10 are hinged at by universal joint and corner impact frame 9 and link block 5.Occur in collision
When, based on Central Collisions frame 8 and central buffer component, supplemented by corner impact frame 9 and angle Buffer Unit, energy is carried out jointly
Buffering.
In order to further increase the energy-absorbing effect of collapse type energy absorbing tube 6, maximize the effect of collapse type energy absorbing tube 6, more
Good way is that the middle section of the collapse type energy absorbing tube 6 is also arranged with support ring 11, and the support ring 11 is by pull rod 12 in
The heart collides the top connection of frame 8, and the both ends of the pull rod 12 are hinged at collision frame and support ring 11 respectively.Pass through support
Ring 11 makes crumple direction along the axial direction of itself the carry out crumple guiding of collapse type energy absorbing tube 6, thus by collapse type energy absorbing tube
6 energy-absorbing effect maximizes.
In addition, due to collide occur when, the damage of vehicle except directly by impact force size influenced in addition to, also and its
Between ground there is biggish frictional force to have direct correlation.For this purpose, preferably way is that the Central Collisions frame 8 and angle are touched
It hits frame 9 to be connected and composed by hollow rod, several electromagnet 20 parallel with one another is uniformly arranged inside the hollow rod, it is described
Pressure sensor 21 is set on making contact head 7, and the electromagnet 20 is triggered by pressure sensor 21.Making contact head 7 with
When vehicle contact, pressure sensor 21 detects pressure signal and feeds back to control system, and control system control electromagnet 20 is opened
Open, thus being adsorbed on Central Collisions frame 8 and corner impact frame 9 tightly by vehicle, keep vehicle directly liftoff or reduce vehicle with
Frictional force between ground, to reduce the damage that vehicle is subject to.Electromagnet 20 of the present invention is using side in parallel or independent wiring
Formula and power supply are connected, and can be prevented 20 failure of electromagnet caused by line impairment during collision, be improved work
Stability.
