[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figures 1 to 4 The utility model provides a car bumper with significant anti-collision effect, including a crossbeam 2 and a buffer shell 1 connected to the front end of the crossbeam 2. A connecting mechanism and a shock absorbing mechanism are connected between the crossbeam 2 and the buffer shell 1. Two connecting mechanisms and shock absorbing mechanisms can be provided, and they are specifically selected according to the size of the bumper. A large number of connecting mechanisms and shock absorbing mechanisms can be selected for a large-sized bumper. The shock absorbing mechanism includes a buffer seat 7, two side seats 8, two moving blocks 10, two springs 12, a sliding block 14, and a spring 2 15. The end of the buffer seat 7 is fixed in the crossbeam 2, and the buffer seat 7 is used to guide the sliding block 14 to improve the stability of the movement of the sliding block 14. The spring 2 15 is used to drive the sliding block 14 to move in a direction close to the moving block 10, the side seat 8 is used to guide the moving block 10, and the spring 1 12 is used to drive the moving block 10 to move in a direction away from the side seat 8. The buffer shell 1 is connected to an extrusion block 9, and the extrusion block 9 matches the two moving blocks 10.
[0020] When slightly impacted, the extrusion block 9 moves toward the buffer seat 7, pushing the two moving blocks 10 away from each other, the spring 12 is compressed, and the buffer rod 4 pushes the guide block 16 backward, and the spring 3 17 is compressed, achieving a better buffering effect. At this time, the extrusion block 9 has not been completely inserted into the buffer seat 7. The end face of the extrusion block 9 is Figure 3 In a, the straight surface of the moving block 10 is b, and a and b are not connected.
[0021] When subjected to a large impact, spring 12 is further compressed, the extrusion block 9 hits the sliding block 14, spring 2 15 is compressed, the extrusion block 9 is fully inserted into the buffer seat 7, and spring 3 17 is further compressed, which can absorb a large impact force and achieve a good buffering effect. At the same time, the compressed spring 12 drives the moving block 10 to return to its position, limits the extrusion block 9, and prevents the buffer shell 1 from rebounding, avoiding hitting the pedestrian and causing secondary damage to him. At this time, a is connected to b.
[0022] The connection mechanism includes a buffer rod 4, a connection tube 5, a guide block 16, and a spring 3 17. Both ends of the buffer rod 4 are connected to the guide block 16 and the buffer shell 1. The guide block 16 is slidably connected in the connection tube 5. The end of the connection tube 5 is fixed in the cross beam 2. The spring 3 17 is used to drive the guide block 16 to move toward the buffer shell 1. The connection mechanism connects the buffer shell 1 and the cross beam 2 on the one hand, and absorbs impact force on the other hand. When the buffer shell 1 is hit, the buffer rod 4 pushes the guide block 16 to move backward, and the spring 3 17 is compressed, thereby absorbing the impact force.
[0023] The spring three 17 is located in the connecting tube 5 , and both ends of the spring three 17 are connected to the guide block 16 and the connecting tube 5 .
[0024] The shock absorbing mechanism also includes two guide columns 11 and two connectors 13. The two ends of the guide columns 11 are connected to the moving block 10 and the connectors 13. The connectors 13 are located at the ends of the side seats 8. The guide columns 11 pass through the ends of the side seats 8 to further guide the moving block 10. Secondly, when the extrusion block 9 is fully inserted into the buffer seat 7, the connectors 13 on both sides can be pulled to allow the guide columns 11 to drive the moving block 10 to move until a and b are separated, thereby loosening the extrusion block 9. The compressed spring 2 15 pushes the sliding block 14 to move, driving the extrusion block 9 to move out of the buffer seat 7. The operation is simple and convenient. At this time, the moving block 10 has not completely moved into the side seat 8, and b faces the sliding block 14 to limit the position. Then the connector 13 is released, and the two moving blocks 10 automatically return to their positions.
[0025] The spring 12 is sleeved on the guide column 11 , and the two ends of the spring 12 are connected to the moving block 10 and the side seat 8 , and the side seat 8 is fixed on both sides of the buffer seat 7 .
[0026] The second spring 15 is located in the buffer seat 7 , and both ends of the second spring 15 are connected to the sliding block 14 and the buffer seat 7 .
[0027] A plurality of connecting plates 3 are connected to the inner side of the buffer shell 1, and a connecting rod 6 is connected to the end of the extrusion block 9. The ends of the connecting rod 6 and the buffer rod 4 are connected to the corresponding connecting plates 3. Compared with the direct connection between the connecting rod 6, the buffer rod 4 and the buffer shell 1, the set connecting plates 3 can increase the contact area with the buffer shell 1, and can reduce the degree of damage to the buffer shell 1 when impacted.
[0028] The elastic coefficient of spring two 15 is greater than that of spring one 12 and spring three 17, and can absorb greater impact force.
[0029] Working principle: When subjected to a slight impact, the buffer shell 1 moves toward the direction of the crossbeam 2, the connecting rod 6 drives the extrusion block 9 to move forward, and squeezes the two moving blocks 10. The two moving blocks 10 move away from each other, and the spring 12 is compressed, while the buffer rod 4 drives the guide block 16 to move, and the spring 3 17 is compressed, which can absorb the impact force well. At this time, a and b are not connected. When subjected to a larger impact, the extrusion block 9 is fully inserted into the buffer seat 7, and the extrusion block 9 hits the sliding block 14. The spring 2 15 is compressed, and the spring 3 17 is further compressed, which can absorb a larger impact force, achieving a good buffering effect and a significant anti-collision effect. At the same time, the compressed spring 12 drives the moving block 10 to return to its position, limits the extrusion block 9, and prevents the buffer shell 1 from rebounding, avoiding hitting the pedestrian and causing secondary damage to him. At this time, a is connected to b.
