Problems solved by technology
[0005] 1. The existing anti-climbing energy-absorbing device is an independent device, and its volume is large, occupying most of the space at the front of the driver's cab, which directly affects the overall head shape design of the driver's cab and the installation of other components;
[0006] 2. The existing anti-climbing energy-absorbing device increases the manufacturing cost of the whole vehicle;
[0007] 3. The existing anti-climbing energy-absorbing device is connected to the rigid structure of the car body through fasteners. During operation, the fastness of the bolts needs to be checked regularly to reduce the efficiency of vehicle maintenance

The invention provides a train collision-resistant energy-absorbing structure. The structure comprises an anti-collision wall which is arranged at the front end of the cab of a train, a mounting basewhich is arranged at the front end of the anti-collision wall and is connected with the anti-collision wall through an energy absorption beam and a column A, a front end part which is positioned belowthe mounting base and is connected with the mounting base at an obtuse angle, and a coupler joist mounted to the front end part. By means of the train collision-resistant energy-absorbing structure,integration of the energy absorption structure and existing components of the train head can be achieved, independent installation is not needed any more, the collision anti-creeping and energy absorption effects can be achieved, the manufacturing and using cost is greatly reduced, and meanwhile the maintenance efficiency of the train is improved.
Description
technical field [0001] The present invention generally relates to the technical field of rail vehicles, and more specifically, relates to a train collision-resistant energy-absorbing structure. Background technique [0002] In the design of trains—especially high-speed trains—the safety of vehicles is one of the most important design directions, especially when vehicles collide, how to minimize damage to vehicles and vehicle occupants is a key issue in vehicle design. content that needs to be considered. [0003] The existing EMU anti-climbing energy-absorbing design is based on the actual collision performance of the vehicle, and 2-4 independent anti-climbing energy-absorbing devices are installed around the coupler at the front end of the driver's cab. The main components of the anti-climbing energy-absorbing device are composed of anti-climbing teeth, deformation energy-absorbing units, mounting seats and other components. The energy-absorbing performance of the deformat...
