[0002] The anti-collision beam is a device used to reduce the impact energy when the vehicle is hit. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car.

[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0022] Example:
[0023] like Figure 1-Figure 3 As shown, a novel high-safety buffering energy-absorbing curved automobile anti-collision beam comprises a mounting plate 1, the ends of the mounting plate 1 are symmetrically provided with mounting holes 2, both ends of the front surface of the mounting plate 1 are symmetrically provided with fixed guide blocks 3, the inner side of the fixed guide blocks 3 is movably connected with an auxiliary deflection buffer beam 4, the front surface of the mounting plate 1 is symmetrically provided with a buffer spring 8, one end of the buffer spring 8 is fixedly connected with a first fixed connecting block 7, the surface of the first fixed connecting block 7 is fixedly connected with an anti-collision beam body 6, both ends of the anti-collision beam body 6 and one end of the auxiliary deflection buffer beam 4 are fixedly connected with fixed positioning rods 9, and the outer side of the surface of the fixed positioning rod 9 is movably sleeved with a movable connecting arm 5.
[0024] The working principle of the above technical solution is as follows:
[0025] During use, the buffering and energy absorption can be mainly carried out through the contraction of the buffer spring 8. When encountering a more serious collision, the anti-collision beam body 6 and the auxiliary deflection buffer beam 4 can be fixed by forming a fulcrum through the contact between the anti-collision beam body 6 and the mounting plate 1, and the anti-collision beam body 6 itself can be deformed to absorb buffering energy, which is easy to use.
[0026] In another embodiment, if Figure 3 As shown, the auxiliary deflection buffer beam 4 includes a beam body 13, a fixed positioning rod 9 is located at one inner end of the beam body 13, the other end of the beam body 13 is fixedly connected to a second fixed connecting block 14, the surface of the second fixed connecting block 14 is fixedly connected to a connecting end block 15, and a connecting guide limit rod 16 is fixedly connected between the upper and lower surfaces of the connecting end block 15.
[0027] When the anti-collision beam body 6 moves, it can drive the movable connecting arm 5 to move, so that the beam body 13 drives the second fixed connecting block 14, the connecting end block 15 and the connecting guide limit rod 16 to deflect, and at the same time, the connecting end block 15 and the connecting guide limit rod 16 move on the inner side of the fixed guide block 3. During this process, they will be pushed by the buffer spring 8, so that they can be used stably, and at the same time, the anti-collision beam body 6 can be restricted to prevent the anti-collision beam body 6 from tilting downward.
[0028] In another embodiment, if Figure 2 As shown, a reinforcing plate 10 is provided inside the beam body 13 and the anti-collision beam body 6 , and the upper and lower surfaces of the reinforcing plate 10 are in contact with the end of the fixed positioning rod 9 .
[0029] The reinforcing plate 10 can improve the overall use strength of the beam body 13 and the anti-collision beam body 6, and is easy to operate.
[0030] In another embodiment, if Figure 2 As shown, the outer surface of the movable connecting arm 5 is slidably fitted with the inner side of the beam body 13 and the anti-collision beam body 6 , and the outer surfaces of the fixed positioning rod 9 and the reinforcing plate 10 .
[0031] This facilitates the movable connecting arm 5 to be stably located between the beam body 13 and the anti-collision beam body 6 and on the outside of the surface of the fixed positioning rod 9 and the reinforcing plate 10 for stable use.
[0032] In another embodiment, if Figure 1 As shown, the cross-sectional shape of the fixed guide block 3 is L-shaped.
[0033] It is convenient to fix the guide block 3 so as to stably limit the connection end block 15 and the connection guide limit rod 16 .
[0034] In another embodiment, if Figure 3 As shown, the upper and lower surfaces of the connecting end block 15 are slidably fitted with the inner side of the end of the fixed guide block 3 , and the outer side of the surface of the connecting guide limit rod 16 is slidably fitted with the inner side of the fixed guide block 3 .
[0035] The connecting end block 15 and the connecting guide limit rod 16 can stably move inside the fixed guide block 3, and the operation is convenient.
[0036] In another embodiment, if Figure 1 As shown, the surface of the mounting plate 1 is symmetrically provided with a fixing sleeve 11 , and the surface of the first fixing connection block 7 is symmetrically provided with a guide rod 12 , and the outer surface of the guide rod 12 and the inner surface of the fixing sleeve 11 are slidably fitted to each other.
[0037] When the anti-collision beam body 6 moves laterally, the guide rod 12 can move inside the fixed sleeve 11 , which is easy to operate.
[0038] The working principle of the utility model is as follows: during use, the mounting plate 1 is connected to the chassis of the automobile. When impacted, the anti-collision beam body 6 will move, causing the buffer spring 8 to contract, thereby buffering and absorbing energy. At the same time, the anti-collision beam body 6 will drive the movable connecting arm 5 to deflect the beam body 13 and the second fixed connecting block 14, so that the connecting end block 15 and the connecting guide limit rod 16 can deflect on the inner side of the fixed guide block 3. When the impact force is large, the end of the beam body 13 and the end of the anti-collision beam body 6 will contact each other with the surface of the mounting plate 1 to form a fulcrum to resist the collision. When the impact force is too large, the anti-collision beam body 6 itself is deformed to buffer and absorb energy. The structure is simple and the operation is convenient and quick.
[0039] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
