[0021] Reference Figures 1 to 4 The utility model embodiment of the aluminum profile automobile anti-collision beam includes a main beam body 1, and the left and right sides of the main beam body 1 are connected with the side beam body 2 by bolts. The top of the main beam body 1 is provided with a mounting groove 9, and the mounting groove 9 is slidably connected with a lower protective plate 3. The left and right sides of the lower protective plate 3 are connected with sliders by bolts near the bottom, and the left and right inner walls of the mounting groove 9 are provided with sliding grooves matching the sliders. The top of the lower protective plate 3 passes through the mounting groove 9 and extends to the top of the main beam body 1 and is movably connected with an upper protective plate 4. The bottom of the inner cavity of the mounting groove 9 is connected with an electric cylinder 10 by bolts, and the top of the push rod of the electric cylinder 10 is connected to the bottom of the lower protective plate 3 by bolts. The bottom of the lower protective plate 3 is provided with grooves 12 near the left and right sides, and the top of the inner cavity of the groove 12 is connected with a first buffer spring 11 by bolts, and the bottom end of the first buffer spring 11 passes through the groove 12 and is connected to the bottom of the inner cavity of the mounting groove 9.

[0022] At both sides near the bottom of the upper protection plate 4, lifting plates 13 are connected by bolts. At both sides near the top of the lower protection plate 3, vertical grooves 14 matching the lifting plates 13 are provided. At the bottom of the lifting plate 13, a second buffer spring 18 is connected by bolts, and the bottom end of the second buffer spring 18 is connected by bolts to the bottom of the inner cavity of the vertical groove 14. An activity groove 8 communicating with the vertical groove 14 is provided on the front wall of the lower protection plate 3, and a resisting plate 7 is slidably connected in the activity groove 8. At both sides near the rear wall of the resisting plate 7, extrusion blocks 20 are connected by bolts. On the lifting plate 13, right-angled trapezoidal grooves 19 matching the extrusion blocks 20 are provided. At the rear wall of the extrusion block 20, a moving rod 15 is connected by bolts, and a perforation matching the moving rod 15 is provided on the rear inner wall of the vertical groove 14. A flexible plate 16 is attached to the rear wall of the lower protection plate 3, and the rear ends of the two moving rods 15 pass through the perforation and are connected to the front wall of the flexible plate 16. At the bottom near the rear wall of the extrusion block 20, an arc-shaped spring piece 17 is connected by bolts, and the rear side of the arc-shaped spring piece 17 passes through the right-angled trapezoidal groove 19 and is connected to the rear inner wall of the vertical groove 14. Through this structure, it can be effectively extended, so that it can effectively prevent collisions and provide protection, increasing its protection area and improving its anti-collision and protection efficiency.

[0023] At the left and right sides of the lower protection plate 3, limit blocks 6 are connected by bolts, and on the side of the side beam body 2 opposite to the lower protection plate 3, limit grooves 5 matching the limit blocks 6 are provided. Through this structure, the position of the lower protection plate 3 can be effectively limited, and it can effectively ensure that the lower protection plate 3 can move smoothly.

[0024] Working principle: When this technical solution is used, first, the main beam body 1 and the side beam body 2 are installed at the required positions. The electric cylinder 10 can be connected to the vehicle power supply through a power cord, and the control switch can be installed in the vehicle cab. At this time, the push rod on the electric cylinder 10 extending upward or contracting downward can drive the lower protection plate 3 to slide upward or downward in the installation groove 9. The lower protection plate 3 drives the upper protection plate 4 to move upward or downward. At the same time, the lower protection plate 3 drives the limit blocks 6 to slide upward or downward in the limit grooves 5, which can effectively adjust the positions of the lower protection plate 3 and the upper protection plate 4, so that it can be effectively extended, so that it can effectively prevent collisions and provide protection, increasing its protection area and improving its anti-collision and protection efficiency. If a collision occurs, the resisting plate 7 contacts the collision object first. At this time, the resisting plate 7 drives the extrusion block 20 to move backward in the right-angled trapezoidal groove 19. Since the hypotenuse of the right-angled trapezoidal groove 19 is set with the front higher than the rear, the extrusion block 20 presses against the inclined surface at the top of the inner cavity of the right-angled trapezoidal groove 19, causing the lifting plate 13 to move upward, and the lifting plate 13 drives the upper protection plate 4 to move upward, which can achieve secondary extension, improving its protection efficiency and increasing its protection area.

However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
