Description

Technical Field

[0001] This utility model relates to the field of automotive bumper technology, specifically a multi-buffered automotive bumper. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts and protect the front and rear of the vehicle. They are usually composed of an outer panel, buffer material, and crossbeams. The outer panel is generally made of plastic, which has a certain degree of toughness and aesthetics. Cars are usually equipped with car bumpers, but some problems still occur in the actual use of existing car bumpers.

[0003] For example, patent application number CN202222803904.0 discloses an automobile bumper assembly, including a bumper body. The bumper body is U-shaped and has a first square groove on its convex end. A first laser scanner is installed at the bottom of the first square groove, and a first warning flashing light is installed at the top of the first square groove. The bumper body has second square grooves on both sides. This design reduces the probability of the bumper body being scratched or bumped. Existing automobile bumper anti-collision structures are generally relatively simple and cannot effectively protect the car when subjected to severe collisions, thus affecting the effectiveness of the automobile bumper.

[0004] To address the aforementioned issues, a multi-buffered car bumper is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-buffered car bumper. By using this device, the problem that the existing car bumper's anti-collision structure is generally too simple and cannot effectively protect the car when subjected to severe collisions, thus affecting the bumper's performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-buffered car bumper, including a mounting bracket and a crash plate disposed at the bottom of the mounting bracket. A connecting plate is fixedly connected to the bottom of the mounting bracket, and a mounting block is fixedly connected to one end of the crash plate. Two sets of mounting blocks and connecting plates are provided. A crash layer is fixedly connected to the outer side of the crash plate. The crash plate is provided with a fixing mechanism, which serves to disassemble the crash plate. The fixing mechanism includes a placement block fixedly connected to the top of the crash plate.

[0007] Preferably, the connecting plate has a mounting groove, which slides with the mounting block, and a reflective strip is fixedly connected to one side of the mounting frame.

[0008] The core of the above-mentioned structural design lies in achieving the initial positioning and assembly guidance of the anti-collision plate and the mounting frame through the "sliding fit between the mounting groove and the mounting block". The size of the mounting groove is precisely matched with the mounting block, which can guide the mounting block to quickly embed into the connecting plate during assembly, avoiding the anti-collision plate from shifting during installation, ensuring the accurate relative position of the anti-collision plate and the mounting frame, and laying the foundation for the precise installation of the subsequent fixing mechanism.

[0009] Preferably, the reflective strips are provided in multiple sets, and the bottom of the mounting frame is provided with a placement groove, which is provided in multiple sets.

[0010] With the above-mentioned structural design, multiple sets of reflective strips are evenly distributed along the side of the mounting bracket, which can expand the light reflection range. No matter which angle the light shines from in front of the vehicle, it can form a clear reflective warning effect, further enhancing the safety warning function in low visibility environments.

[0011] Preferably, the placement groove and the placement block are slidably engaged, the reflective strip is provided with a fixing screw, and a threaded groove is provided on one side of the placement block.

[0012] The above-mentioned structural design is the key to achieving "quick assembly and disassembly" of the crash barrier; the sliding fit between the placement slot and the placement block provides lateral restraint for the crash barrier, while the fixing screw that passes through the reflective strip and the threaded groove on the placement block achieves longitudinal fixation.

[0013] Preferably, the threaded groove matches the fixing screw, an inner support plate is fixedly connected to the inner side of the mounting bracket, and an airbag is also fixedly connected to the inner side of the inner support plate.

[0014] The design of the above structure, with the precise matching of the threaded groove and the fixing screw, ensures a firm connection after the screw is screwed in, preventing the screw from loosening due to vibration during vehicle operation and ensuring the reliability of the anti-collision plate.

[0015] Preferably, an airbag is provided on one side of the anti-collision plate, a connecting plate is fixedly connected to one side of the airbag, and a buffer plate is fixedly connected to the inner side of the anti-collision plate.

[0016] The above-mentioned structural design forms the core of the "multi-buffer system". When the outer side of the anti-collision plate is hit, the impact force is first evenly transferred to the airbag through the connecting plate 2. The airbag 1 absorbs part of the impact force quickly through gas compression, thus achieving "first-level buffering".

[0017] Preferably, a support plate one is fixedly connected inside the anti-collision plate, and a support plate two is also fixedly connected inside the anti-collision plate, with the support plate one located inside the support plate two.

[0018] The design of the above structure aims to balance the "buffering performance" and "structural stability" of the crash barrier. Support plate one and support plate two can be made of high-strength alloy materials, forming a "double-layer support frame" that can prevent the crash barrier from excessively deforming or breaking when it is hit, and also provide installation support for the buffer components inside the crash barrier.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application, through the setting of support plate one, support plate two, airbag one, and anti-collision plate, achieves a multi-layered buffering effect for the anti-collision plate, improves the overall structural performance, and solves the problem that the existing anti-collision structure of automobile bumpers is generally too simple and cannot effectively protect the car when subjected to severe collisions during use, thus affecting the performance of the automobile bumper.

[0021] 2. This application, through the setting of fixing screws, placement slots, placement blocks and reflective strips, enables workers to easily replace the anti-collision plate, which facilitates the subsequent use of the device. It solves the problem that the existing anti-collision structure of automobile bumpers is generally integrated and installed, which makes it inconvenient for workers to replace the anti-collision plate when it is damaged, thus increasing the overall cost of the structure.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Combination Figures 1-3 A multi-buffered car bumper includes a mounting bracket 1 and a crash plate 2 disposed at the bottom of the mounting bracket 1. A connecting plate 11 is fixedly connected to the bottom of the mounting bracket 1. A mounting block 21 is fixedly connected to one end of the crash plate 2. Two sets of mounting blocks 21 and connecting plates 11 are provided. A crash layer 22 is fixedly connected to the outer side of the crash plate 2. The crash plate 2 is provided with a fixing mechanism, which serves to disassemble the crash plate 2. The fixing mechanism includes a placement block 221 fixedly connected to the top of the crash plate 2.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that existing car bumper structures are generally too simple and fail to provide effective protection against severe collisions, thus affecting their performance, this embodiment discloses the following technical solution, specifically as follows: Figures 1-5As shown, an inner support plate 13 is fixedly connected to the inner side of the mounting bracket 1, and an airbag 21 is also fixedly connected to the inner side of the inner support plate 13. An airbag 123 is also provided on one side of the anti-collision plate 2, and a connecting plate 231 is fixedly connected to one side of the airbag 123. A buffer plate 232 is fixedly connected to the inner side of the anti-collision plate 2, and a support plate 1233 is fixedly connected to the inside of the anti-collision plate 2. A support plate 234 is also fixedly connected to the inside of the anti-collision plate 2. The support plate 1233 is located inside the support plate 234. During use, when the anti-collision layer 22 is impacted, the impact force will act on the surface of the connecting plate 231. The connecting plate 231 moves, thereby compressing the airbag 123. The airbag 123 then acts as a buffer plate on the anti-collision plate 2. To achieve a buffering effect, the buffer plate 232 on the inner side of the anti-collision plate 2 can provide further buffering. The support plate 1 233 and the support plate 234 can support the anti-collision plate 2 and prevent it from deforming during a collision. The reflective strip 12 on the outer side of the mounting frame 1 allows the car to reflect light to alert people at night. The inner support plate 13 on the inner side of the mounting frame 1 improves the overall structural strength of the mounting frame 1. The airbag 2 131 improves the effectiveness of the device. When the anti-collision plate 2 is hit by a collision, the mounting frame 1 can also receive a buffering effect, realizing a multi-layered buffering effect for the anti-collision plate 2 and improving the overall structural effectiveness.

[0034] Example 2:

[0035] To address the issue that existing car bumper anti-collision structures are generally integrated, making replacement inconvenient for workers when the anti-collision plate 2 is damaged, thus increasing the overall structure's usage cost, this embodiment discloses the following technical solution, specifically as follows: Figure 2 and Figure 3As shown, the connecting plate 11 has a mounting groove 111, which slides with the mounting block 21. A reflective strip 12 is fixedly connected to one side of the mounting bracket 1, and multiple sets of reflective strips 12 are provided. A placement groove 121 is provided at the bottom of the mounting bracket 1, and multiple sets of placement grooves 121 slide with the placement block 221. A fixing screw 122 passes through the reflective strip 12. A threaded groove 222 is provided on one side of the placement block 221, and the threaded groove 222 matches the fixing screw 122. If the anti-collision plate 2 is damaged during use, it can be repaired by loosening the screw located on the mounting bracket 11. The fixing screw 122 on one side rotates, causing one end of the fixing screw 122 to come out from the inside of the placement block 221, thereby allowing the anti-collision plate 2 to be removed from the bottom of the mounting bracket 1. When installation is required, the mounting block 21 at one end of the anti-collision plate 2 is aligned with the connecting plate 11 and inserted. At this time, the placement block 221 moves into the placement groove 121, thereby fixing the anti-collision plate 2. Then, the fixing screw 122 on one side of the mounting bracket 1 is turned in the opposite direction to complete the installation of the anti-collision plate 2. This allows the staff to easily replace the anti-collision plate 2, facilitating the subsequent use of the device.
