Technical Field

[0001] This utility model belongs to the field of bumper technology, specifically an impact-resistant bumper protection device. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts and protect the front and rear of the vehicle. With the continuous improvement of the national economic level and the increasing number of cars, traffic conditions are becoming more and more complex. As the front and rear mounting devices of a vehicle, bumpers play an important role in protecting the lives of drivers and passengers in traffic accidents. Therefore, designing a bumper protection device with good impact resistance and excellent protective performance is one of the urgent problems to be solved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an impact-resistant bumper protection device to address the above-mentioned defects.

[0005] Furthermore, the auxiliary buffer cylinder has an accommodating groove inside that matches the stop member.

[0006] Furthermore, the anti-compression component includes an annular anti-compression body and two horizontal supports symmetrically arranged on both sides of the annular anti-compression body. The two ends of the outer surface of the annular anti-compression body respectively abut against the third buffer slider and the stop member. One end of the horizontal support is connected to the annular anti-compression body, and the other end abuts against the inner wall of the auxiliary buffer cylinder. The stop members on the same side are arranged at intervals.

[0007] Furthermore, the connector has a hollow hourglass-shaped cross-section. The two side walls of the connector include a first horizontal segment, a first inclined segment, a middle horizontal segment, a second inclined segment, and a second horizontal segment. The first inclined segment is located at the rear end of the first horizontal segment, the middle horizontal segment is located at the rear end of the first inclined segment, the second inclined segment is located at the rear end of the middle horizontal segment, and the second horizontal segment is located at the rear end of the second inclined segment.

[0008] The beneficial effects of this utility model are:

[0009] This utility model utilizes a combination of a reinforcing plate, a fixing block, a mounting cylinder, a first connecting rod, a first buffer slider, a first buffer spring, a second buffer slider, a second buffer spring, an auxiliary buffer cylinder, a second connecting rod, a third buffer slider, a stopper, a pressure-resistant component, and a connecting component. The reinforcing plate increases the structural strength and rigidity of the bumper body, improving its protective and deformation resistance. When the bumper body collapses towards the anti-collision beam assembly due to impact, the connecting component supports and resists the external impact. After deformation, the fixing block moves along with it, driving the first connecting rod to slide inward into the mounting cylinder, causing the first buffer slider to slide and compress the first buffer spring. The first buffer spring pushes the second buffer slider, and the second buffer slider compresses the second buffer spring to mitigate the external impact. Simultaneously, the second connecting rod and the third buffer slider compress the pressure-resistant component, causing it to deform and resist the impact. Their combined action improves the bumper's impact resistance, effectively protecting the safety of drivers and passengers. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Reference Figure 1-3 As shown, the impact-resistant bumper protection device includes a bumper body 1 and a crash beam assembly 2. The bumper body 1 has a mounting part for connecting to the vehicle, and mounting holes are evenly distributed on its upper part. A reinforcing plate 3 is provided on the rear end face of the bumper body 1. The reinforcing plate 3 is fixed to the rear end face of the bumper body 1, increasing the wall thickness of the bumper body 1, increasing its structural strength and rigidity, increasing its impact resistance and deformation resistance, and improving the protection of the bumper body. A fixing block 4 is provided on the rear end face of the reinforcing plate 3. The fixing block 4 can be welded or fixed to the reinforcing plate 3 by bolts. A mounting cylinder 5 is provided on the front end face of the crash beam assembly 2. The mounting cylinder 5 can also be fixedly connected to the crash beam assembly 2 by welding or bolts. The crash beam assembly 2 consists of a crash beam and an energy-absorbing box. A first connecting rod 6 extending horizontally into the interior of the mounting cylinder 5 is provided at the end of the fixing block 4 near the mounting cylinder 5. The first connecting rod 6 can slide inside the mounting cylinder 5. Inside the mounting cylinder 5, a first buffer slider 7 is provided on the first connecting rod 6, which is slidably connected to the inner wall of the mounting cylinder 5. A first buffer spring 8 is provided at the rear end of the first buffer slider 7. A second buffer slider 9, which is slidably connected to the inner wall of the mounting cylinder 5, is provided at the rear end of the first buffer spring 8. A second buffer spring 10 is provided at the rear end of the second buffer slider 9. When the bumper body 1 collapses due to impact towards the anti-collision beam assembly 2, the fixing block 4 moves together, driving the first connecting rod 6 to slide into the mounting cylinder 5, driving the first buffer slider 7 to slide, compressing the first buffer spring 8, pushing the second buffer slider 9, and compressing the second buffer spring 10. After multiple releases of the external impact, it is then transmitted to the anti-collision beam assembly 2, making it effectively resist the external impact and effectively protect the personal safety of the driver and passengers in an accident, thus improving its protective performance.

[0017] Auxiliary buffer cylinders 11 are symmetrically arranged on both sides of the mounting cylinder 5. Second connecting rods 12, which extend horizontally into the auxiliary buffer cylinders 11, are symmetrically arranged on both sides of the first connecting rod 6. The second connecting rods 12 move together with the fixing block 4. When the first connecting rod 6 moves into the mounting cylinder 5, they also move into the auxiliary buffer cylinder 11. A third buffer slider 13 is provided on the second connecting rod 12 and is slidably connected to the inner wall of the auxiliary buffer cylinder 11. The third buffer slider 13 moves together with the second connecting rod 12. A stop member 14 is provided inside the auxiliary buffer cylinder 11. The stop member 14 has a T-shaped cross-section. A receiving groove 1101 matching the stop member 14 is opened inside the auxiliary buffer cylinder 11. The vertical rod of the stop member 14 is fixed inside the receiving groove 1101. An anti-compression component 15 is provided between the stop member 14 and the third buffer slider 13. The stop member 14 cooperates with the third buffer slider 13 to restrict the anti-compression component 15 between them, so that the anti-compression component 15, the third buffer slider 13, and the stop member 14 are on the same central axis.

[0018] A connector 16 is provided between the reinforcing plate 3 and the anti-collision beam assembly 2, which is staggered with the mounting cylinder 5. One end of the connector 16 is fixedly connected to the reinforcing plate 4, and the other end is fixedly connected to the anti-collision beam assembly 2. The connector 16 makes the connection between the bumper body and the anti-collision beam assembly 2 more secure, and provides support for the bumper body under external impact to resist external impact. In addition, its hollow structure makes it lighter and facilitates its deformation to release impact force under stress, making it less likely to intrude into the engine compartment.

[0019] The anti-compression component 15 includes an annular anti-compression body 1501 and two horizontal support bodies 1502 symmetrically arranged on both sides of the annular anti-compression body 1501. The two ends of the outer surface of the annular anti-compression body 1501 abut against the third buffer slider 13 and the stop member 14, respectively. One end of the horizontal support body 1502 is connected to the annular anti-compression body 1501, and the other end abuts against the inner wall of the auxiliary buffer cylinder 11. The stop members 14 on the same side are arranged at intervals. The horizontal support body 1502 makes the anti-compression component 15 stably form a limit within the auxiliary buffer cylinder 11. When the third buffer slider 13 applies pressure to the annular anti-compression body 1501, it produces a concave deformation to mitigate the external force and drive the front horizontal support body to move closer to the rear horizontal support body to absorb energy through deformation and mitigate the external impact.

[0020] The connector 16 has a hollow hourglass-shaped cross-section. The two side walls of the connector 16 include a first horizontal segment 1601, a first inclined segment 1602, a middle horizontal segment 1603, a second inclined segment 1604, and a second horizontal segment 1605. The first inclined segment 1602 is located at the rear end of the first horizontal segment 1601, the middle horizontal segment 1603 is located at the rear end of the first inclined segment 1602, the second inclined segment 1604 is located at the rear end of the middle horizontal segment 1603, and the second horizontal segment 1605 is located at the rear end of the second inclined segment 1604. Between the two first inclined sections 1602, there is a tapered structure that gradually narrows from front to back, and between the two second inclined sections 1604, there is a tapered structure that gradually widens from front to back. The first inclined sections 1602 and the second inclined sections 1604 are symmetrically arranged with the middle horizontal section as the center. When the connector 16 is subjected to force deformation, the first inclined section moves closer to the second inclined section, and the included angle formed gradually narrows, which limits the direction of deformation. The deformation resists and absorbs external force, preventing the connector 16 from directly intruding into the engine compartment.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
