[0001] This utility model belongs to the technical field of anti-collision beam brackets. Specifically, this utility model relates to an anti-collision beam bracket structure. Background Technology

[0002] Existing automotive anti-collision beams not only significantly increase manufacturing and development costs, but also greatly increase the number of manufacturing and assembly steps, which not only prolongs assembly time but also increases the probability of assembly errors. At the same time, the excessive number of sub-parts directly increases the weight of the assembly, which has an adverse effect on the vehicle's fuel economy and handling performance. In terms of later maintenance, the large number of sub-parts makes repair or replacement work more time-consuming and costly, causing inconvenience to users.

[0003] Chinese Patent (Publication No.: 217145896U) discloses a crash beam mounting bracket and a vehicle crash beam with the bracket, relating to the field of vehicle technology. The crash beam mounting bracket includes a base plate, an energy-absorbing box, and a mounting part. The mounting part includes a mounting plate one, a mounting plate two, and a limiting shaft. The mounting plate one includes a support plate one and a fixing shaft fixedly connected to the support plate one, the fixing shaft having a limiting hole. The mounting plate two includes a support plate two and a sleeve fixedly connected to the support plate two. The bottom of the support plate two has a pin hole one for the fixing shaft to pass through, and the sleeve has a pin hole two. The energy-absorbing box has a pin hole three. The sleeve is fitted onto the energy-absorbing box, and the limiting shaft passes through the pin hole three, the pin hole two, and the limiting hole to connect the mounting part and the energy-absorbing box as a single unit. This crash beam has many parts, resulting in high cost and inconvenient maintenance. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a simple and low-cost anti-collision beam support structure. To achieve the above objective, the technical solution adopted by this utility model is as follows: an anti-collision beam support structure, including an anti-collision beam and a fixed support, wherein a limiting structure is provided on the fixed support, and the anti-collision beam is connected to the limiting structure.

[0005] The limiting structure includes a limiting arc surface, and the anti-collision beam is disposed on the limiting arc surface.

[0008] The limiting arc surface is located at the corner of the fixed plate, and the fixed plate has a protrusion that abuts against the anti-collision beam.

The limiting arc surface is directly formed at the corner of the fixed plate, and the protrusion is on the fixed plate.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] like Figures 1-2As shown, a crash beam support structure includes a crash beam 3 and a fixed support 1. A limiting structure 2 is provided on the fixed support 1, and the crash beam 3 is connected to the limiting structure 2. The crash beam 3 is the core load-bearing component of the entire structure. When a vehicle collision occurs, the crash beam 3 absorbs and transmits collision energy through its own deformation, reducing the impact on the vehicle body and occupants. The limiting structure 2 ensures that the collision force is evenly distributed on the fixed support 1, preventing excessive local stress that could lead to structural damage.

[0020] The limiting structure 2 includes a limiting arc surface 201, to which the anti-collision beam 3 is connected. The anti-collision beam 3 is welded to the limiting arc surface 201, which is a quarter-circle arc. The limiting arc surface 201 positions and limits the anti-collision beam 3, ensuring that it maintains the correct position during installation and operation. The limiting arc surface 201 is welded to the outer surface of the anti-collision beam 3 in close contact. This close-fitting connection increases the contact area between the two, allowing the force on the anti-collision beam to be evenly transmitted to the fixed bracket 1 through the arc surface during a collision, preventing premature damage to the anti-collision beam 3 or the fixed bracket 1 due to excessive local stress. In addition, the limiting arc surface 201 has a certain elastic buffering capacity, absorbing some energy through slight deformation when subjected to impact, further improving the structure's impact resistance.

[0021] The fixed bracket 1 includes a fixed plate 101, with lower brackets 4 connected to both ends of the fixed plate 101. The lower brackets 4 are connected to the vehicle body. A limiting arc surface 201 is provided on the fixed plate 101. The fixed bracket 1 is used to connect the anti-collision beam 3. The lower brackets 4 are provided at both ends of the fixed plate 101 and connected to the vehicle body. The lower brackets 4 stably transmit the force from the fixed bracket 1 to the vehicle body, while providing stable support for the entire anti-collision beam 3.

[0022] The lower support 4 includes a support plate 401, which is disposed at both ends of the fixed plate 101. One end of the support plate 401 is connected to the base plate 402. The support plate 401 is disposed at both ends of the fixed plate 101 and extends perpendicularly to the fixed plate 101. One end of the support plate 401 is connected to the base plate 402, forming an L-shaped structure. This structural design can effectively disperse the vertical and horizontal forces transmitted from the fixed plate 101, thereby enhancing the load-bearing capacity of the lower support 4.

[0023] A limiting arc surface 201 is located at the corner of the fixed plate 101. A protrusion 5 is provided on the fixed plate 101, which abuts against the anti-collision beam 3. One corner of the fixed plate 101 is the limiting arc surface 201, and the other corner is the protrusion 5. The protrusion 5 is located on the fixed plate 101 and abuts against the anti-collision beam 3. The protrusion 5 provides additional support and limitation to the anti-collision beam 3 from the inside, working in conjunction with the limiting arc surface 201 to constrain the position of the anti-collision beam 3 and prevent it from swaying or shifting under impact. During operation, when the anti-collision beam 3 tends to shift inward under impact, the protrusion 5 provides a reverse supporting force, preventing the shift.

[0024] An arc-shaped transition section 6 is provided at the connection between the base plate 402 and the support plate 401. The arc-shaped transition section 6, located at the connection between the base plate 402 and the support plate 401, eliminates stress concentration at the connection point, improving the structural strength and fatigue resistance of the lower support 4. In traditional right-angle connection structures, the connection is prone to significant stress concentration due to force transmission, making it susceptible to breakage under long-term use or impact. The arc-shaped transition section 6, with its smooth curve transition, allows force to be evenly transmitted at the connection point, reducing stress accumulation.

[0025] The fixed bracket 1 is a one-piece molded structure. The one-piece molded structure of the fixed bracket 1 greatly improves the overall strength and rigidity of the structure, avoids weak points that may occur when splicing multiple parts, and reduces assembly steps and assembly errors.

[0026] A threaded hole 7 is provided on the base plate 402, which is bolted to the vehicle body. The threaded hole 7 is provided on the base plate 402 to realize the bolted connection between the base plate 402 and the vehicle body, providing a reliable interface for the connection between the lower bracket 4 and the vehicle body, and ensuring that the entire anti-collision beam 3 assembly can be firmly installed on the vehicle body. The bolted connection has the characteristics of high connection strength and good disassembly, which facilitates the installation, maintenance and replacement of the anti-collision beam 3.

[0027] The role and effect of the embodiments

[0028] The fixed bracket 1 is a one-piece molded structure, eliminating the need for multiple sub-components and directly reducing the number of parts, thus avoiding the assembly complexity problems caused by numerous parts in traditional structures. The limiting arc surface 201 is directly molded into the corner of the fixed plate 101, and the protrusion 5 is on the fixed plate 101. In the event of a collision, the force on the anti-collision beam 3 can be evenly transmitted to the fixed bracket 1 through the arc surface, preventing premature damage to the anti-collision beam 3 or the fixed bracket 1 due to excessive local stress. In addition, the limiting arc surface 201 has a certain elastic buffering capacity, which can absorb some energy through slight deformation when subjected to impact force, further improving the impact resistance of the structure. The protrusion 5 forms additional support and limitation for the anti-collision beam 3 from the inside, working together with the limiting arc surface 201 to constrain the position of the anti-collision beam 3 and prevent the anti-collision beam 3 from shaking or shifting when subjected to impact force.

[0029] The base plate 402 of the lower bracket 4 is bolted to the vehicle body via threaded holes 7, allowing for quick disassembly and assembly without special tools, thus reducing the difficulty of maintenance. It also reduces assembly difficulty. The overall structure is simple, easy to install and maintain, has low design cost, fewer parts, reduces heat buildup, and occupies less interior space.

[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
