[0025] The lengthened beam body 1 comprises an inner side plate 10, an outer side plate 11 and an intermediate plate 12, the middle position of the inner side plate 10 is a hollow frame and the both ends are expanded sheet bodies, and the outer side plate 11 and the intermediate plate 12 are both arc-shaped plate bodies; the connecting mechanism 3 comprises a flange plate 6 and a connecting disc 5, the connecting disc 5 is connected with the lengthened beam body 1, the flange plate 6 located at the front side is used for connecting an automobile bumper beam, and the flange plate 6 located at the rear side is used for connecting with the connecting frame 2.

[0026] The rear end of the connecting frame 2 is directly connected with the automobile longitudinal beam.

[0027] The upper and lower ends of the lengthened beam body 1 are both provided with a cover plate 4, the cover plate 4 covers the upper and lower ends of the whole composed of the inner side plate 10, the outer side plate 11 and the intermediate plate 12, and the front and rear ends of the cover plate 4 are both connected with the connecting disc 5, so that the component structures (i.e. the inner side plate 10, the outer side plate 11 and the intermediate plate 12) in the lengthened beam body 1 are tightly connected, thereby more truly simulating the component structure of the automobile front longitudinal beam, which is beneficial to the later automobile collision experiment result, and further beneficial to the teaching of cutting, sheet metal repairing and the like by teaching personnel and the learning of students.

[0028] The edges of the upper and lower ends of the inner side plate 10, the outer side plate 11 and the intermediate plate 12 are both provided with uniformly distributed mounting holes 7 for connecting with cross beams, and the uniformly distributed mounting holes 7 facilitate the connection of the cross beams arranged at different positions, thereby improving the convenience degree during installation.

[0029] A plurality of connecting holes 9 are formed at the edge of the flange plate 6 and the connecting plate 5, for the insertion of bolts, and the connection of the flange plate 6 and the connecting plate 5 is achieved by bolts, which facilitates the disassembly and replacement of the front end module of the longitudinal beam in the later stage, and further facilitates the learning and operation of students.

[0030] A plurality of stamping holes 8 are formed at the edge of the connecting frame 2 away from the lengthened beam body 1, which are uniformly distributed and used for stamping connection with the automobile longitudinal beam. The stamping connection between the front end module of the longitudinal beam and the front longitudinal beam of the automobile is firm.

[0031] The materials of the inner side plate 10, the outer side plate 11 and the middle plate 12 are the same as those of the automobile longitudinal beam, and the thicknesses of the inner side plate 10, the outer side plate 11 and the middle plate 12 are the same as that of the automobile longitudinal beam.

[0033] Specifically, the special-shaped end of the connecting frame 2 is aligned with the front longitudinal beam of the automobile, and the connection is completed by stamping, and then the flange plate 6 and the connecting plate 5 on the connecting mechanism 3 are connected in sequence, and then the lengthened beam body 1 is installed, and finally the automobile anti-collision beam is installed. When the automobile collision experiment is performed, the anti-collision beam at the front end of the automobile receives the impact force and releases it in sequence through the anti-collision beam, and then the vibration is transmitted to the front end module, so as to achieve the crash or damage of the front end module. When the teaching staff teaches, the structure and composition of the front end module simulating the front longitudinal beam of the automobile are achieved, that is, the cutting and sheet metal teaching of the automobile longitudinal beam are completed through the front end module, thereby reducing the replacement cost of the front longitudinal beam of the automobile after the collision experiment, and reducing the operation difficulty of students and the guidance complexity of the teaching staff.

[0034] In summary: in the collision teaching experiment of the front longitudinal beam of the automobile, the front end module of the longitudinal beam simulates the front longitudinal beam of the automobile, which facilitates the teaching of students and reduces the replacement cost of the front longitudinal beam of the automobile and the teaching difficulty.
