Description

Technical Field

[0001] This utility model relates to the field of automotive bumper technology, specifically to a bumper side support structure and a vehicle. Background Technology

[0002] During vehicle operation, the front bumper serves as a crucial aesthetic and protective component, and its stability impacts the vehicle's normal use and safety. Defects in the front bumper's support structure can lead to its complete failure, affecting the vehicle's appearance integrity, collision protection capabilities, and even posing safety hazards.

[0003] Currently, the design of the front bumper side bracket usually adopts the method of connecting to the outside of the front anti-collision beam of the vehicle frame. That is, the side bracket is fixed only through the mounting point on the outside of the anti-collision beam, and all mounting points are on the same plane, forming a cantilever structure.

[0004] Because the side bracket is a cantilever structure, connecting only to the outer side of the crash beam with its mounting points on the same plane, the overall stiffness of the side bracket is poor, especially the structural strength at the root of the cantilever. Limited by this stiffness, the natural frequency of the side bracket is low, making it prone to resonating with or matching the excitation frequency from the road surface during vehicle operation. When the natural frequency of the side bracket resonates with the road excitation frequency, it increases the vibration amplitude of the side bracket, leading to fatigue or stress concentration and ultimately causing the side bracket to fail, resulting in the failure of the entire front bumper. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a bumper side support structure and a vehicle. To achieve the above objectives, in a first aspect, this application provides a bumper side support structure, comprising: Side support body; The connecting bracket assembly includes: A first connecting bracket is connected to one side of the anti-collision beam in the width direction, and the first connecting bracket is connected to the side bracket body; The second connecting bracket is connected to the side of the anti-collision beam away from the first connecting bracket in the width direction, and the second connecting bracket is connected to the side bracket body.

[0007] In this technical solution, the bumper side bracket, through the cooperation of the side bracket body and the connecting bracket assembly, achieves simultaneous connection with both the inner and outer sides of the vehicle's anti-collision beam. Compared to existing technologies where the side bracket is only connected to the outer side of the anti-collision beam to form a single planar cantilever structure, this solution connects the side bracket body to both the inner and outer sides of the anti-collision beam simultaneously through the connecting bracket assembly. This is equivalent to forming a wrap-around connection with the anti-collision beam, which can utilize the rigidity of the anti-collision beam itself to improve the rigidity of the cantilever structure's root mounting point and mitigate the structural rigidity difference caused by the outer connection.

[0008] In some embodiments of this application, the first connecting bracket and the second connecting bracket are both connected to the same side of the side bracket body.

[0009] In the technical solution, same-side connection ensures that the force direction of the two connecting brackets is concentrated on the same plane of the side bracket body, so that the stress is transmitted in a single direction, avoiding the generation of torque and reducing the risk of structural failure. If the first and second connecting brackets are connected to the two sides of the side bracket body respectively, the side bracket body will form a bidirectional stress cantilever. When the vehicle vibrates or there is a slight collision, the force direction of the two brackets is prone to deviate, which may cause the connection point to loosen or the body to deform after long-term use.

[0010] In some embodiments of this application, a first reinforcing bracket is included, which is disposed on the side of the side bracket body away from the second connecting bracket; The second connecting bracket and the side bracket body are connected to the side of the first reinforcing bracket away from the first connecting bracket by fasteners; The first connecting bracket and the side bracket body are connected to the side of the first reinforcing bracket near the first connecting bracket by fasteners.

[0011] In the technical solution, the second connecting bracket is located on the outside of the anti-collision beam. The side of the side bracket body closest to the second connecting bracket is already supported by the second connecting bracket, while the side away from the second connecting bracket, that is, the side of the side bracket body closest to the anti-collision beam, is the weakest point in terms of support. The first reinforcing bracket and the second connecting bracket clamp the side bracket body, increasing the rigidity of the side bracket body's support arm, thus changing the side bracket body from being subjected to force on one side to being subjected to force on both sides. That is, there is a connecting bracket on the side close to the second connecting bracket and a reinforcing bracket on the side away from it, thereby improving the bending resistance of the side bracket body.

[0012] In some embodiments of this application, a first reinforcing bracket is included, which is disposed on the side of the side bracket body near the second connecting bracket; The side of the second connecting bracket and the first reinforcing bracket away from the first connecting bracket is connected to the side bracket body by fasteners; The side of the first connecting bracket and the first reinforcing bracket near the first connecting bracket is connected to the side bracket body by fasteners.

[0013] In this technical solution, the second connecting bracket provides single-point support on the outer side of the side bracket body, while the first reinforcing bracket is located on the side of the side bracket body near the second connecting bracket, effectively adding a rigid reinforcing arm next to the outer force-bearing point. This structure improves the bending stiffness of the outer side of the side bracket body, resisting bending deformation in the outer area when the vehicle encounters road bumps or minor collisions, thus preventing cantilever structure failure due to insufficient outer support.

[0014] In some embodiments of this application, the first reinforcing bracket is configured as a stepped type; The connection surface between the side support body and the first connecting bracket is defined as the first stepped surface, and the connection surface between the side support body and the second connecting bracket is defined as the second stepped surface. The stepped surfaces at different positions of the first reinforcing bracket are respectively connected to the first stepped surface and the second stepped surface on the side bracket body.

[0015] In the technical solution, the side support body has bends or height differences due to connection requirements, forming connection parts on different planes. The stepped surface of the first reinforcing support can match these non-coplanar structures. Through multiple stepped segments, it fits and connects with different plane parts of the side support body, avoiding loosening of connections or local stress concentration caused by structural misalignment, so that the first reinforcing support and the side support body form a stable whole.

[0016] In some embodiments of this application, the side bracket support structure further includes a second reinforcing bracket, one end of which is fixedly connected to the bumper, and the other end is fitted to the side bracket body on the side away from the second connecting bracket.

[0017] In the technical solution, the connection points between the side support body and the first connecting bracket, and the second connecting bracket, are close to the anti-collision beam. The area of ​​the side support body far from the anti-collision beam lacks direct support and therefore has weaker rigidity. The second reinforcing bracket, by establishing a connection with the bumper in this area, forms an additional support structure, effectively improving the rigidity of the middle area of ​​the side support body and preventing deformation or vibration in this area due to insufficient rigidity.

[0018] In some embodiments of this application, the connection end of the second reinforcing bracket and the bumper is fixed to the bumper by a locking member; The locking component includes a threaded portion and a connecting hole concentric with the threaded hole of the threaded portion; one side of the connecting hole is connected to one side of the threaded portion, and a snap-fit ​​cavity is formed between the threaded portion and the connecting hole; The snap-fit ​​cavity snaps into the mounting hole of the bumper, and the threaded part, mounting hole and snap-fit ​​hole are connected to the bumper by fasteners.

[0019] In the technical solution, the locking part's snap-fit ​​cavity is directly snapped into the bumper's mounting hole. The fit between the snap-fit ​​cavity and the mounting hole solves the problem of no threads in the mounting hole. The snap-fit ​​cavity can first position and initially fix the locking part and the bumper, aligning the threaded part, the connecting hole and the bumper's mounting hole. Then, screws or bolts are passed through the through hole, snap-fit ​​hole and mounting hole of the second reinforcing bracket in sequence and screwed into the threaded hole of the threaded part.

[0020] In some embodiments of this application, the first connecting bracket is provided with a protruding connecting surface facing closer to the side bracket body, the protruding connecting surface being used to fit and connect with the side bracket body.

[0021] In this technical solution, the raised connecting surface can form a tight surface contact when connected to the side support body, eliminating loosening caused by manufacturing errors or assembly gaps. This avoids vibration noise or stress concentration caused by gaps and enhances the stability of the connection between the side support body and the inner side of the anti-collision beam.

[0022] In some embodiments of this application, the second connecting bracket is provided with a reinforcing part to improve the bending resistance of the second connecting bracket.

[0023] In the technical solution, since the second connecting bracket is located on the outside of the anti-collision beam, it needs to cooperate with the first connecting bracket on the inside to form a wrapping connection to the anti-collision beam, and it itself needs to withstand a certain load. The reinforcement can improve the bending stiffness of the second connecting bracket, making it less prone to bending deformation under stress, and ensuring the stability of the connection with the side bracket body and the anti-collision beam.

[0024] In a second aspect, this application provides a vehicle including a crash beam, a bumper, and a bumper side support structure as described in the first aspect; The bumper side support structure is used to fix the side of the bumper to one end of the anti-collision beam.

[0025] In this technical solution, the bumper side support structure used in the vehicle improves its structural rigidity and natural frequency by connecting to the inner and outer sides of the anti-collision beam and adding reinforcing brackets. Applying this to the vehicle reliably fixes the side of the bumper to one end of the anti-collision beam, avoiding the failure problem caused by resonance in traditional side supports. This improves the stability and safety of the bumper during vehicle operation and reduces vehicle appearance damage or reduced protective capabilities caused by bumper failure.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that during vehicle operation, the front bumper, as an important appearance and protective component, affects the normal use and safety of the vehicle. If the support structure of the front bumper is defective, it may cause the entire bumper to fail, thereby affecting the vehicle's appearance integrity and collision protection capabilities, and even creating safety hazards.

[0033] Currently, the design of the front bumper side bracket usually adopts the method of connecting to the outside of the front anti-collision beam of the vehicle frame. That is, the side bracket is fixed only through the mounting point on the outside of the anti-collision beam, and all mounting points are on the same plane, forming a cantilever structure.

[0034] Because the side bracket is a cantilever structure, connecting only to the outer side of the crash beam, and with the mounting points on the same plane, the overall stiffness of the side bracket is poor, especially the structural strength at the root of the cantilever. Limited by this stiffness, the natural frequency of the side bracket is low, making it prone to resonating with or matching the excitation frequency from the road surface during vehicle operation. When the natural frequency of the side bracket resonates with the road surface excitation frequency, it increases the vibration amplitude of the bracket, causing it to fail due to fatigue or stress concentration, ultimately leading to the failure of the entire front bumper.

[0035] Based on this, this application proposes a bumper side support structure and vehicle. By connecting the side bracket of the bumper to the inner and outer sides of the front anti-collision beam, welding a first connecting bracket to the inner side of the anti-collision beam, and retaining the second connecting bracket on the outer side (which can be made smaller), the side bracket and the anti-collision beam form a wrap-around connection. At the same time, the connection point between the side bracket and the bumper body is increased, a first reinforcing bracket is added to form a triangular cavity to improve the stiffness at the bend, and a second reinforcing bracket is added to improve the stiffness of the middle area. This improves the overall stiffness of the side bracket structure and solves the problems of poor stiffness, low natural frequency, easy resonance, and eventual failure caused by the side bracket only connecting to the outer side of the anti-collision beam to form a cantilever structure in the prior art.

[0036] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings. As attached Figures 1 to 9 As shown in an illustrative embodiment of the bumper side support structure and vehicle of this application, the bumper side support structure includes a side bracket body 1 and a connecting bracket assembly 2. The side bracket body 1 is connected to both the inner and outer sides of the vehicle's anti-collision beam 5 through the connecting bracket assembly 2.

[0037] The bumper 6 side bracket achieves synchronous connection with both the inner and outer sides of the vehicle's anti-collision beam 5 through the cooperation of the side bracket body 1 and the connecting bracket assembly 2. Compared to the planar cantilever structure formed by the side bracket only connecting to the outer side of the anti-collision beam 5 in the prior art, this solution uses the connecting bracket assembly 2 to simultaneously fix the side bracket body 1 to both sides of the anti-collision beam 5, forming a wrap-around connection layout for the anti-collision beam 5. This design utilizes the structural rigidity of the anti-collision beam 5 itself, strengthens the side bracket mounting point, and overcomes the problem of insufficient overall rigidity caused by the single outer side connection mode.

[0038] The increased stiffness of the connection points improves the overall stiffness of the side bracket structure, thereby raising the natural frequency of the bumper 6 side bracket body 1. This ensures that the natural frequency of the bumper 6 is higher than the excitation frequency from the road surface during vehicle operation, preventing bracket failure and bumper 6 failure due to resonance.

[0039] This solution connects the bracket assembly 2 to both sides of the anti-collision beam 5 without taking up too much additional space in the front of the vehicle. While improving structural performance, it also takes into account space utilization and avoids the problem of excessive space occupation caused by structural improvements.

[0040] In some embodiments, the bracket assembly 2 includes a first connecting bracket 21 and a second connecting bracket 22. The first connecting bracket 21 is connected to one side of the anti-collision beam 5 in the width direction and is connected to the side bracket body 1. The second connecting bracket 22 is connected to the side of the anti-collision beam 5 away from the first connecting bracket 21 in the width direction and is connected to the side bracket body 1.

[0041] In this embodiment, a three-dimensional connection is formed on both sides of the anti-collision beam 5, and the side bracket body 1 is supported from the inside or outside or above and below the anti-collision beam by two connecting brackets. The rigidity of the cantilever root mounting point is enhanced, which solves the problem of poor rigidity caused by a single outer connection.

[0042] The anti-collision beam 5 is connected on both sides, which can distribute the load of the side support body 1 along two paths from the first connecting bracket 21 to the anti-collision beam 5 and from the second connecting bracket 22 to the anti-collision beam 5, avoid the load being concentrated in a single area of ​​the anti-collision beam 5, reduce the stress peak at the root of the cantilever of the side support body, and extend the service life of the structure.

[0043] In some embodiments, the first connecting bracket 21 and the second connecting bracket 22 are both connected to the same side of the side bracket body 1.

[0044] Same-side connection ensures that the force direction of the two connecting brackets is concentrated on the same plane of the side bracket body 1, so that the stress is transmitted in a single direction, avoiding torque generation and reducing the risk of structural failure. If the first and second connecting brackets 22 are connected to the two sides of the side bracket body 1 respectively, the side bracket body 1 will form a bidirectional force cantilever. When the vehicle vibrates or there is a slight collision, the force direction of the two brackets is prone to deviate. Long-term use may cause the connection point to loosen or the body to deform.

[0045] After the first connecting bracket 21 and the second connecting bracket 22 are connected on the same side, the direction of the load they transmit is consistent with the main force direction of the anti-collision beam 5. The lateral stiffness of the anti-collision beam 5 can be used to bear the load, rather than letting the anti-collision beam 5 bear additional longitudinal or torsional loads, thereby ensuring the rationality of the overall structure's stress.

[0046] Preferably, both the second connecting bracket 22 and the first connecting bracket 21 can be designed to be lightweight. Under the premise of ensuring structural strength, weight-reducing holes are opened in non-stressed areas through hollow design to reduce weight and reduce overall load, while not affecting the reliability of connection with the side bracket body 1 and the anti-collision beam 5.

[0047] In some embodiments, the bumper side support structure further includes a first reinforcing bracket 3, which is disposed on the side of the side bracket body 1 away from the second connecting bracket 22; the second connecting bracket 22, the side bracket body 1 and the side of the first reinforcing bracket 3 away from the first connecting bracket 21 are connected by fasteners 11; the first connecting bracket 21, the side bracket body 1 and the side of the first reinforcing bracket 3 near the first connecting bracket 21 are connected by fasteners 11.

[0048] Furthermore, the first reinforcing bracket 3 is made of aluminum alloy and formed through a die-casting process, making it lighter than a steel bracket. This reduces the overall weight of the side brackets and improves the ride comfort of the vehicle.

[0049] The second connecting bracket 22 is located on the outside of the anti-collision beam 5. The side of the side bracket body 1 closest to the second connecting bracket 22 is supported by the second connecting bracket 22, while the side away from the second connecting bracket 22, that is, the side of the side bracket body 1 closest to the anti-collision beam 5, is a weak support area. The first reinforcing bracket 3 and the second connecting bracket 22 clamp the side bracket body 1, increasing the rigidity of the side bracket body 1 and changing the side bracket body 1 from being subjected to force on one side to being subjected to force on both sides. That is, there is a connecting bracket on the side close to the second connecting bracket 22 and a reinforcing bracket on the side away from it, thus improving the bending resistance of the side bracket body 1.

[0050] The connection nodes of the first connecting bracket 21, the second connecting bracket 22, and the side bracket body 1 are the points where forces converge. This solution uses fasteners 11 as connecting bolts. One connecting bolt passes through one side of the second connecting bracket 22, the side bracket body 1, and the first reinforcing bracket 3, while the other two connecting bolts pass through the other side of the first connecting bracket 21, the side bracket body 1, and the first reinforcing bracket 3. Each connection node is a rigid three-part connection. The first reinforcing bracket 3 acts as a rigid liner, increasing the stiffness of the connection point and improving the node's shear and tensile resistance, thus preventing loosening due to insufficient node stiffness.

[0051] The first reinforcing bracket 3 is located on the side of the side bracket body 1 away from the second connecting bracket 22, and indirectly forms a triangular arrangement with the first connecting bracket 21 and the second connecting bracket 22 through the side bracket body 1. The first connecting bracket 21 is the inner support point, the second connecting bracket 22 is the outer support point, and the first reinforcing bracket 3 is the supplementary support point. All three are fixed to the side bracket body 1 by bolts and fasteners 11. Road surface excitation during vehicle operation, the self-weight load of the bumper 6, etc., can be distributed to the three support points through this closed loop, rather than concentrated at the cantilever root of the side bracket body 1, thus reducing the peak stress at the root and avoiding the risk of connection fatigue failure.

[0052] In some embodiments, a first reinforcing bracket 3 is included, which is disposed on the side of the side bracket body 1 near the second connecting bracket 22; the sides of the second connecting bracket 22 and the first reinforcing bracket 3 away from the first connecting bracket 21 are connected to the side bracket body 1 by fasteners 11; the sides of the first connecting bracket 21 and the first reinforcing bracket 3 near the first connecting bracket 21 are connected to the side bracket body 1 by fasteners 11. The fasteners 11 can be bolts, and the first connecting bracket 21 and the second connecting bracket 22 are fixed to the anti-collision beam 5 by welding. When welding is used, a continuous full welding process is used at the contact edge between the inner side of the anti-collision beam 55 and the first connecting bracket 21.

[0053] The second connecting bracket 22 provides single-point support on the outer side of the side bracket body 1, while the first reinforcing bracket 3 is located on the side of the side bracket body 1 near the second connecting bracket 22, which is equivalent to adding a rigid reinforcing arm next to the outer force support point. This structure improves the bending stiffness of the outer side of the side bracket body 1, and can resist bending deformation in the outer area when the vehicle encounters road bumps or minor collisions, thus avoiding cantilever structure failure due to insufficient outer support.

[0054] In some embodiments, the first reinforcing bracket 3 is configured as a stepped type; the connection surface on the side bracket that is connected to the first connecting bracket 21 is defined as the first stepped surface, and the connection surface on the side bracket that is connected to the second connecting bracket 22 is defined as the second stepped surface; the stepped surfaces at different positions of the first reinforcing bracket 3 are used to connect to the first stepped surface and the second stepped surface on the side bracket body 1 respectively.

[0055] Due to connection requirements, the side support body 1 has bends or height differences, forming connection parts on different planes. The stepped surface of the first reinforcing support 3 can match these non-coplanar structures. Through multiple stepped segments, it fits and connects with different plane parts of the side support body 1, avoiding loosening of connections or local stress concentration caused by structural misalignment, so that the first reinforcing support 3 and the side support body 1 form a stable whole.

[0056] Both the first reinforcing bracket 3 and the side bracket body 1 have a stepped structure. The first and second stepped surfaces on the side bracket body 1 respectively mate with the stepped surfaces of the first reinforcing bracket 3, or the opposite surfaces of the first and second stepped surfaces on the side bracket body 1 respectively mate with the stepped surfaces of the first reinforcing bracket 3. The corresponding connecting surfaces between the stepped surfaces form surface contact, solving the gap caused by structural misalignment, avoiding abnormal noises from component collisions caused by gaps during vehicle operation, and reducing connection loosening caused by gaps. The stepped design can be adjusted to adapt to the contours of different bumpers 6 and anti-collision beams 5 by adjusting the height difference of the steps.

[0057] In some embodiments, the side bracket support structure further includes a second reinforcing bracket 4, one end of which is fixedly connected to the bumper 6, and the other end is fitted to the side bracket body 1 on the side away from the second connecting bracket 22.

[0058] Because the connection points between the side support body 1 and the first connecting bracket 21 and the second connecting bracket 22 are close to the anti-collision beam 5, the area of ​​the side support body 1 far from the anti-collision beam 5 is less rigid due to the lack of direct support. The second reinforcing bracket 4 forms an additional support structure by establishing a connection with the bumper 6 in this area, effectively improving the rigidity of the middle area of ​​the side support body 1 and preventing deformation or vibration in this part due to insufficient rigidity.

[0059] The second reinforcing bracket 4 directly connects the bumper 6 to the side bracket body 1. When the middle area of ​​the side bracket body 1 is under load, the load can be transferred to the bumper 6 through the second reinforcing bracket 4. The structural rigidity of the bumper 6 is used to support the side bracket body 1 in the opposite direction, improving the deformation resistance of the middle area and preventing overloading of the side bracket body 1.

[0060] The middle area of ​​the side support body 1 is weak in rigidity. Even if there is no resonance at the root, the area far from the root may experience local vibration due to insufficient local rigidity. After the second reinforcing support 4 is attached to this area, it can suppress local vibration through its own rigidity, reduce the accumulation of vibration energy in the middle area, reduce the overall vibration amplitude, and ensure the stability of the bumper 6.

[0061] In some embodiments, the connection end of the second reinforcing bracket 4 and the bumper 6 is fixed to the bumper 6 by a locking member 41; the locking member 41 includes a threaded portion 411 and a connecting hole 412 concentric with the threaded hole of the threaded portion 411. One side of the connecting hole 412 is connected to one side of the threaded portion 411, and a snap-fit ​​cavity is formed between the threaded portion 411 and the connecting hole 412. The snap-fit ​​cavity snaps into the mounting hole of the bumper 6, and the threaded portion, the mounting hole, and the snap-fit ​​hole are connected to the bumper 6 by a fastener 11.

[0062] The locking part 41 has a snap-fit ​​cavity that snaps directly into the mounting hole of the bumper 6. The fit between the snap-fit ​​cavity and the mounting hole solves the problem of no thread in the mounting hole. The snap-fit ​​cavity can first position and initially fix the locking part and the bumper 6, so that the threaded part, the connecting hole and the mounting hole of the bumper 6 are aligned. Then, screws or bolts are passed through the through hole, snap-fit ​​hole and mounting hole of the second reinforcing bracket 4 in sequence and screwed into the threaded hole of the threaded part.

[0063] The threaded part of the locking component can be designed as a standard thread, and the inner diameter of the connecting hole matches the rod diameter of the corresponding fastener 11. There is no need to redesign the locking component due to differences in vehicle models, which can meet the installation requirements of different vehicle models, avoid repeated development, and reduce design and manufacturing costs.

[0064] In some embodiments, the first connecting bracket 21 is provided with a protruding connecting surface 211 facing the side bracket body 1, and the protruding connecting surface 211 is used to fit and connect with the side bracket body 1.

[0065] The raised connecting surface 211 can form a tight surface contact when connected with the side bracket body 1, reducing loosening of the connection due to manufacturing errors or assembly gaps. It avoids vibration noise or stress concentration caused by gaps and enhances the stability of the connection between the side bracket body 1 and the inner side of the anti-collision beam 5.

[0066] If the connection part of the side bracket body 1 has a slight curvature or tilt angle, the raised connection surface 211 can adapt to it by its own shape, so that the posture during connection is more stable and avoids excessive local stress caused by mismatch of contact surfaces.

[0067] In some embodiments, the second connecting bracket 22 is provided with a reinforcing portion to improve its bending resistance. The reinforcing portion may be a folded edge 221 on the second connecting bracket 22, or it may be a reinforcing rib.

[0068] Since the second connecting bracket 22 is located on the outside of the anti-collision beam 5, it needs to cooperate with the first connecting bracket 21 on the inside to form a wrapping connection to the anti-collision beam 5, and it itself needs to bear a certain load. The reinforcement can improve the bending stiffness of the second connecting bracket 22, making it less prone to bending deformation under stress, and ensuring the stability of the connection with the side bracket body 1 and the anti-collision beam 5.

[0069] Furthermore, the first connecting bracket 21 has a folded edge 221 on its edge, which also enhances the bending resistance of the second connecting bracket 22. Since the second connecting bracket 22 and the first connecting bracket 21 form a wrapping connection to the anti-collision beam 5, the second connecting bracket 22 itself needs to withstand a certain load. The folded edge 221 structure increases the moment of inertia of the bracket edge, thereby improving the bending stiffness of the second connecting bracket 22, making it less prone to bending deformation under stress, and ensuring the stability of the connection with the side bracket body 1 and the anti-collision beam 5.

[0070] Preferably, near the connection point between the second connecting bracket 22 and the side bracket body 1 and the anti-collision beam 5, the folded edge 221 is designed as a continuous closed structure to enhance the local stiffness around the connection point, make the load transfer more uniform, and reduce stress concentration at the connection point.

[0071] Furthermore, this application protects a vehicle including a crash beam 5, a bumper 6, and a bumper side support structure as described in the first aspect; wherein the bumper side support structure is used to fix the side of the bumper 6 to one end of the crash beam 5.

[0072] The bumper side support structure used in this vehicle, through its connection with the inner and outer sides of the anti-collision beam 5 and the addition of reinforcing brackets, enhances its structural rigidity and natural frequency. When applied to a vehicle, it reliably fixes the side of the bumper 6 to one end of the anti-collision beam 5, avoiding the failure problem caused by resonance in traditional side supports. This improves the stability and safety of the bumper 6 during vehicle operation and reduces the risk of vehicle exterior damage or reduced protective capabilities due to bumper 6 failure.

[0073] The bumper side support structure used in the vehicle, through its connection to the inner and outer sides of the anti-collision beam 5 and the addition of reinforcing brackets, improves structural rigidity and natural frequency. This design secures the side of the bumper 6 to one end of the anti-collision beam 5, avoiding the failure issues caused by resonance in traditional side supports. The bumper 6 remains stable during vehicle operation, reducing the risk of cosmetic damage and reduced protective capabilities due to bracket or bumper 6 failure. Since this bumper side support structure only connects to the anti-collision beam 5, it does not occupy excessive front space and will not interfere with the arrangement of other vehicle components, thus contributing to the efficient use of front space.

[0074] By addressing the issue of resonance failure in the side support structure of the bumper, the front bumper 6 can perform its protective function more stably. In the face of minor collisions or road vibrations, it reduces secondary damage caused by the bumper 6 becoming loose or falling off, thereby improving the vehicle's safety and durability.

[0075] It should be noted that, depending on the size difference of the anti-collision beam 5 for different vehicle types, the length and connection point position of the bumper side support structure are adjusted to ensure that the side of the bumper 6 can be fixed to the anti-collision beam 5 in different models, thereby improving the effect of strengthening the connection rigidity.

[0076] Furthermore, the stiffness parameters of the bumper side support structure are incorporated into the overall vehicle anti-collision system design. It is matched with the force characteristics of components such as the anti-collision beam 5 and the energy absorption box. When a collision occurs, the impact force is transferred to the vehicle body through the stable connection of the side bracket, thereby improving the overall anti-collision performance.

[0077] Furthermore, the vehicle's bumper side support structure is made of high-strength aluminum alloy or carbon fiber composite material, which reduces the weight of the front of the vehicle while ensuring structural rigidity and natural frequency, thus helping to improve the vehicle's economy or range.

[0078] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
