[0024] Example 1:

[0025] See also Figures 1 to 5 The utility model discloses an anti-collision beam structure for automobiles, comprising an anti-collision beam 1.

[0026] A buffer device 2 is provided on the rear end face of the anti-collision beam 1, and a quick-install device 3 is provided on the right side of the buffer device 2. The buffer device 2 includes a T-shaped connecting rod 21 bolted to the rear end face of the anti-collision beam 1, the T-shaped connecting rod 21 is slidably connected to the inner side face of the sleeve 22, the sleeve 22 is slidably connected to the opening of the front end face of the square box 23, a damping spring 24 is fixed to the rear end face of the sleeve 22, and the front end face of the damping spring 24 is elastically connected to the T-shaped connecting rod 21, and the anti-collision beam 1 drives the T-shaped connecting rod 21 to squeeze the damping spring 24;

[0027] A connecting plate 25 is welded and fixed to the rear end of the outer side surface of the sleeve 22, and the connecting plate 25 is slidably connected to the inner side surface of the square box 23. An energy-absorbing ball 26 is provided on the rear end surface of the inner side of the square box 23, and the energy-absorbing ball 26 is in contact with the rear end of the sleeve 22. The energy-absorbing ball 26 is made of rubber and will deform when under pressure, thereby performing secondary buffering and offsetting the collision energy. The outer sides of the T-shaped connecting rod 21 and the sleeve 22 are coated with a wear-resistant coating to reduce the wear generated by the T-shaped connecting rod 21 and the sleeve 22 during operation, so as to prevent affecting the collision buffering effect of the device.

[0028] The working principle of an anti-collision beam structure for automobiles based on Example 1 is as follows:

[0029] When a collision occurs, the anti-collision beam 1 drives the T-shaped link 21 to squeeze the damping spring 24, and the compression of the damping spring 24 buffers and absorbs the collision energy. Then the anti-collision beam 1 continues to drive the sleeve 22 and the connecting plate 25 to move and apply pressure to the energy-absorbing ball 26. Since the energy-absorbing ball 26 is made of rubber, it will deform when under pressure, and then perform secondary buffering and offsetting of the collision energy, thereby reducing the damage to the car caused by the collision. In this way, when a collision occurs, the compression of the damping spring 24 and the deformation of the energy-absorbing ball 26 can buffer, absorb and offset the energy of the collision, thereby effectively reducing the intensity of the collision and reducing the damage to the car. The device can effectively extend the service life of the anti-collision beam 1.

[0030] Example 2:

[0031] See also Figures 1 to 5 Compared with the first embodiment, the present invention is a kind of anti-collision beam structure for automobiles. The present embodiment further includes: a quick-installing device 3 includes a square box 23 and a mounting sleeve 31 with bolts on the left and right sides. A fixing bracket 32 ​​is slidably mounted on the inner side of the mounting sleeve 31. A pull rod 33 is slidably mounted on the middle through hole at the top of the fixing bracket 32. The fixing bracket 32 ​​provides a platform for mounting other components. The lower ends of the left and right sides of the fixing bracket 32 ​​are provided with a pulling groove 34. The pulling groove 34 on the left side of the fixing bracket 32 ​​is slidably connected to a positioning rod 35. The right side of the positioning rod 35 is elastically connected to a positioning spring 36 installed in the pulling groove 34 on the left side of the fixing bracket 32. The pull rod 33 drives the positioning rod 35 through the pull rope 37 to squeeze and compress the positioning spring 36.

[0032] A pull rope 37 is provided on the right side of the positioning rod 35, and the bottom of the pull rod 33 is fixedly connected to the pull rope 37. The outer side of the pull rod 33 is glued with a ring, and the outer side of the ring is evenly provided with textures to increase the friction between the finger and the pull rod 33. The inner groove of the installation sleeve 31 and the outer side of the fixing frame 32 are coated with a corrosion-resistant coating to prevent the installation sleeve 31 and the fixing frame 32 from being corroded by other substances and affecting the installation effect of the device.

[0033] In this embodiment:

[0034] When the anti-collision beam needs to be maintained or replaced, the pull rod 33 is pulled upward by hand. The pull rod 33 drives the positioning rod 35 through the pull rope 37 to squeeze and compress the positioning spring 36. Then the anti-collision beam 1 and the mounting sleeve 31 are lifted upward to disengage them, and then the pull rod 33 is released. During installation, the anti-collision beam 1 and the mounting sleeve 31 are first connected to the fixing frame 32, and then the pull rod 33 is pulled upward by hand. At this time, the mounting sleeve 31 falls to the bottom of the fixing frame 32 and the pull rod 33 is released. When the positioning spring 36 is reset, the positioning rod 35 is extended, and then the anti-collision beam is quickly fixed. This facilitates the rapid disassembly and assembly of the anti-collision beam 1, effectively improves the disassembly and assembly efficiency of the anti-collision beam 1, and the device can effectively improve the maintenance efficiency of the anti-collision beam 1, and is convenient for use in different environments.
