Abstract
The invention discloses an automobile and an engine cabin longitudinal beam structure thereof. The engine cabin longitudinal beam structure comprises a longitudinal beam body which comprises an inner plate and an outer plate in fixed connection, sectional area of the longitudinal beam body is gradually increased from front to rear, and a crumpling groove concaving towards the inner plate is formed in the outer plate. In this way, in the process when an engine cabin longitudinal beam is collided, the crumpling groove has energy absorbing effect, and when collision force is transmitted to the crumpling groove, the crumpling groove can play a role in reducing and weakening the collision force so as to prevent the same from being directly transmitted to a driving cab, so that passengers are avoided being injured. In addition, the sectional area of the longitudinal beam body is gradually increased from front to rear, stress at the root of the longitudinal beam body is enhanced, and concentration of stress received by the engine cabin longitudinal beam is reduced, so that stress stability of the engine cabin longitudinal beam in the process of vehicle colliding is improved greatly, and safety of the passengers in the driving cab is guaranteed.

Plate 4, and rear reinforcing plate 4 is located at the side of close the rear end of longeron body 1 of crumple groove 2, i.e., after reinforcement
Plate 4 is located at the rear side of crumple groove 2, and after assembling, rear reinforcing plate 4 is located at the close car tail of crumple groove 2
The side in portion.As hereafter reinforcing plate 4 also forms anti-stress protection, the crashworthiness of longeron body 1 is substantially increased
Performance is hit, the intensity of the longitudinal beams of engine cabin structure is improve, engine is further avoid and is entered driving
Room, further ensures the safety of passenger.
For the ease of connection, rear reinforcing plate 4 can be fixedly connected with longeron body 1 by way of welding.
Certainly, rear reinforcing plate 4 can also be fixedly connected otherwise with longeron body 1, such as clamping or
Bolt connection, is not limited thereto.
In addition, the rear reinforcing plate 4 can be fixed on front wall middle cross beam position, in so substantially increasing front wall
The force stability and intensity at crossbeam position.
Preferably, inner panel 1b can also be fixedly connected with outside plate 1a by way of welding, so that interior
Connection between plate 1b and outside plate 1a is more firm.Certainly, can also be by spiral shell between inner panel 1b and outside plate 1a
Tether and connect, be not limited thereto.
It should be noted that the bottom land of crumple groove 2 along the length direction of the longeron body 1 extension away from
From more than zero, i.e., the bottom land of crumple groove 2 is more than zero along the length of the length direction of the longeron body 1,
The energy absorption performance of the crumple groove 2 is so improve, force value wink after impact force is transferred to the crumple groove 2
Between reduce, and ensure that the intensity of crumple groove 2, be unlikely to deform after its stress.
