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.
[0022] See also Figures 1 to 5 The utility model provides a lightweight and high-strength automobile bumper, including a mounting plate 3, a main bar body 1 is arranged at the front end of the mounting plate 3, and the two end axes of the main bar body 1 are connected to the side bar body 2, and the side bar body 2 can rotate around the axis. The mounting plate 3 is connected to a buffer mechanism for absorbing the impact force of the side bar body 2, and the buffer mechanism includes a buffer seat 4, a spring 13, two buffer plugs 12, two sliding blocks 6, and two connecting plates 7. The buffer plug 12 is movably connected to the buffer seat 4, the two ends of the spring 13 are connected to the buffer plug 12, the sliding block 6 is used to drive the buffer plug 12, the mounting plate 3 is used to guide the sliding block 6, the two ends of the connecting plate 7 are connected to the side bar body 2 and the sliding block 6, and the buffer seat 4 is connected to a pressure relief mechanism.
[0023] When the side bar body 2 is hit, the impact direction is Figure 1When the middle X points to the direction, the side bar body 2 rotates immediately, and the rotation direction is the y direction. The sliding block 6 is pushed forward through the connecting plate 7, driving the buffer plug 12 to move toward the middle direction of the buffer seat 4. The space between the two buffer plugs 12 is compressed, which plays a certain buffering role. Secondly, the spring 13 is compressed synchronously, which further plays a buffering energy absorption effect, reduces the impact on the front of the car bumper, and improves the impact resistance of the car bumper. The compressed gas can lift the pressure relief cover 17, and the gas is immediately discharged from the end of the pressure relief pipe 20 for pressure relief treatment. When the buffer plug 12 moves to a suitable position, the stretched spring 3 22 drives the pressure relief cover 17 to return to its position, realizes the blocking of the pressure relief pipe 20, and then limits the buffer plug 12 to prevent the buffer plug 12 from returning to its position, thereby preventing the side bar body 2 from rebounding and causing secondary injuries to pedestrians.
[0024] The buffer mechanism also includes two guide rails 11, a buffer cavity 14, and two push rods 5. The guide rail 11 is fixed to the inner side of the mounting plate 3. The sliding block 6 is slidably connected to the guide rail 11 to improve the stability of the movement of the sliding block 6. The buffer cavity 14 is arranged in the buffer seat 4. The buffer plug 12 is sealingly slidably connected to the buffer cavity 14 to improve the sealing of the connection between the two. The two ends of the push rod 5 are connected to the sliding block 6 and the buffer plug 12.
[0025] The end of the guide rail 11 is connected to the buffer seat 4 , and the buffer seat 4 is fixed to the inner side of the mounting plate 3 . The guide rail 11 limits the buffer plug 12 to prevent it from being separated from the buffer seat 4 .
[0026] The pressure relief mechanism includes a pressure relief cover 17, a pull ring 18, a mounting frame 19, a pressure relief pipe 20, a pressure relief channel 21, and a spring three 22. The pressure relief pipe 20 is connected to the buffer seat 4, the pressure relief channel 21 is arranged in the buffer seat 4, and the pressure relief channel 21 is connected to the buffer seat 4. The mounting frame 19 is fixed in the pressure relief pipe 20. The spring three 22 is used to drive the pressure relief cover 17 to move in the direction close to the mounting frame 19, and the pull ring 18 is connected to the pressure relief cover 17. When the buffer plug 12 moves toward the middle direction of the buffer seat 4, the space between the two buffer plugs 12 is compressed, and the gas pressure gradually increases, so that the pressure relief cover 17 can be lifted up, and the high-pressure gas is discharged from the end of the pressure relief pipe 20 to achieve the purpose of pressure relief. At this time, the spring three 22 is in an elongated state. When the buffer plug 12 moves to a suitable position, the stretched spring three 22 drives the pressure relief cover 17 to return to its original position, so that the pressure relief cover 17 is connected to the end of the pressure relief pipe 20 again, thereby blocking the pressure relief pipe 20 and effectively preventing the buffer plug 12 from returning to its original position, thereby preventing the side bar body 2 from rebounding and causing secondary injuries to pedestrians. When the side bar body 2 needs to return to its original position, a pulling force is applied to the pull ring 18 to separate the pressure relief cover 17 from the pressure relief pipe 20, that is, the pressure relief pipe 20 is connected to the outside world, and the compressed spring one 13 drives the corresponding buffer plug 12 to return to its original position. The buffer plug 12 applies a thrust to the push rod 5 to return the sliding block 6, and simultaneously drives the side bar body 2 to return to its original position, which is simple and convenient to operate.
[0027] The spring three 22 is located in the pressure relief pipe 20 , and both ends of the spring three 22 are connected to the mounting frame 19 and the pressure relief cover 17 .
[0028] The mounting plate 3 is connected with a connecting mechanism, and the end of the connecting mechanism is connected to the main bar body 1. The connecting mechanism includes a fixed seat 8, a cylinder 9, a buffer rod 10, a guide block 15, and a second spring 16. The fixed seat 8 is fixed to the mounting plate 3, the cylinder 9 is connected to the fixed seat 8, the cylinder 9 is used for guiding the guide block 15, the second spring 16 is used to drive the guide block 15 to move in the direction close to the main bar body 1, and the two ends of the buffer rod 10 are connected to the main bar body 1 and the guide block 15. When the main bar body 1 is hit, the main bar body 1 moves in the direction close to the mounting plate 3, pushing the buffer rod 10 to move, so that the guide block 15 slides in the cylinder 9, and the second spring 16 is compressed, which can absorb a large impact force and achieve a good buffering effect.
[0029] The second spring 16 is located in the cylinder 9 , and both ends of the second spring 16 are connected to the guide block 15 and the cylinder 9 .
[0030] The guide block 15 is slidably connected in the cylinder 9, so that the guide block 15 moves stably.
[0031] The main bar body 1 and the side bar body 2 are made of a plastic called polycarbonate, infiltrated with alloy components, and processed by alloy injection molding. The processed bumper has high-strength rigidity, light overall weight, and good painting performance.
[0032] Working principle: When the side bar body 2 is hit, the side bar body 2 rotates along the direction of y, and then the connecting plate 7 pushes the sliding block 6 to move toward the direction of the buffer seat 4. The sliding block 6 applies a thrust to the push rod 5, so that the buffer plug 12 moves toward the middle direction of the buffer seat 4. The space between the two buffer plugs 12 is compressed, which plays a certain buffering role. Secondly, the spring 13 is compressed synchronously, which further plays a buffering energy absorption effect, reduces the impact on the front of the car bumper, and improves the impact resistance of the car bumper. The compressed gas can lift the pressure relief cover 17, and the gas is discharged from the end of the pressure relief pipe 20 to perform the pressure relief operation. The spring three 22 is in an elongated state. When the buffer plug 12 moves to a suitable position, the elongated spring three 22 drives the pressure relief cover 17 to return, so that the pressure relief cover 17 is connected to the end of the pressure relief pipe 20 again, and the pressure relief pipe 20 is blocked, which effectively prevents the buffer plug 12 from returning, thereby preventing the side bar body 2 from rebounding and causing secondary injuries to pedestrians. When the side bar body 2 needs to return to its original position, the pull ring 18 can be pulled to separate the pressure relief cover 17 from the pressure relief pipe 20, and the buffer chamber 14 is connected to the outside world. The compressed spring 13 drives the corresponding buffer plug 12 to return. The buffer plug 12 applies a thrust to the push rod 5 to return the sliding block 6, and simultaneously drives the side bar body 2 to return automatically. The operation is simple and convenient, and the practicability is strong.
