The crossbeam assembly is spaced apart from the subframe and has an initial position and a working position. When the crossbeam assembly is in the initial position, the first and second inclined beam assemblies are in a naturally open state. Applying a force toward the central region to the intermediate connecting plate can deform the first and second inclined beam assemblies to move them to the working position away from the geometric center of the intermediate connecting plate.

At the same time, the limiting assembly can control the deformation range and direction of the crossbeam, avoiding secondary damage to the vehicle structure. The first energy absorption space of the crossbeam assembly can better absorb and disperse energy during a collision, solving the problem of poor energy absorption effect of a single-structure crossbeam in the prior art.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0046] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0047] In the current field of automotive crash protection design, crossbeams, as important structures for resisting collision impacts at the front and rear of a vehicle, are typically designed as single straight beams. While this type of crossbeam can resist impact forces to some extent through its rigidity, its energy absorption effect is quite limited in actual collisions. When a vehicle is involved in a collision, the straight beam often fails to effectively disperse the impact force, instead transferring most of the impact energy directly to the vehicle's main structure. This leads to severe deformation or damage to the body panels, supporting structures, or internal components, posing a threat to passenger safety and imposing a heavy financial burden on car owners due to high repair costs.

[0048] Furthermore, traditional straight beam crossbeams have significant shortcomings in terms of installation and post-collision repositioning. Due to their lack of design flexibility, the installation process often requires precise positioning and fixation, increasing assembly complexity and time costs. More importantly, once a vehicle has experienced a collision, these crossbeams are difficult to reposition themselves or through simple repairs to their original state. Deformed crossbeams either require complex straightening processes to restore their original shape or face direct scrapping, further exacerbating the economic burden of automotive repairs. Simultaneously, if the crossbeam cannot be repositioned, the vehicle's crashworthiness is significantly reduced, thus affecting overall driving safety and service life.

[0049] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a collision avoidance component is provided.

[0050] Specifically, such as Figure 1 and Figure 2As shown, an anti-collision component includes: a crossbeam assembly 20, at least one crossbeam assembly 20, the crossbeam assembly 20 including: a first inclined beam assembly, an intermediate connecting plate 204 and a second inclined beam assembly, a first end of the first inclined beam assembly being connected to a first end of the intermediate connecting plate 204, the first inclined beam assembly and the intermediate connecting plate 204 being arranged at a preset angle, a second end of the intermediate connecting plate 204 being connected to a first end of the second inclined beam assembly, the intermediate connecting plate 204 and the second inclined beam assembly being arranged at a preset angle, and an intermediate region 200 between the first inclined beam assembly and the second inclined beam assembly forming a first energy-absorbing space; and a limiting component, at least one limiting component, the limiting component including: a first limiting sub-assembly 10 and a second limiting sub-assembly 30, the first... The limiting sub-assembly 10 and the second limiting sub-assembly 30 are laterally spaced along the subframe. The first limiting sub-assembly 10 is movably connected to one of the second ends of the first and second inclined beam assemblies, and the second limiting sub-assembly 30 is connected to the other of the second ends of the first and second inclined beam assemblies. The crossbeam assembly 20 is spaced apart from the subframe and has an initial position and a working position. When the crossbeam assembly 20 is in the initial position, the first and second inclined beam assemblies are in a naturally open state. Applying a force toward the intermediate region 200 to the intermediate connecting plate 204 can deform the first and second inclined beam assemblies to move them to the working position away from the geometric center of the intermediate connecting plate 204.

[0051] By applying the technical solution of the present invention, through the cooperation of the crossbeam assembly 20 with the first limiting sub-assembly 10 and the second limiting sub-assembly 30, the collision energy can be absorbed by the deformation of the crossbeam when a collision occurs. At the same time, the limiting components can control the deformation range and direction of the crossbeam, avoiding secondary damage to the vehicle structure. The first energy absorption space of the crossbeam assembly 20 can better absorb and disperse energy during a collision, solving the problem of poor energy absorption effect of a single-structure crossbeam in the prior art.

[0052] Furthermore, the crossbeam assembly 20 is positioned inside the body skin 40, forming a second energy-absorbing space 50 with the body skin 40. The limiting component is spaced apart from the body skin 40. The clever placement of the crossbeam assembly 20 inside the body skin 40, together with the body skin 40, creates the second energy-absorbing space 50. This design not only significantly enhances the vehicle's energy absorption capacity during a collision, effectively mitigating the direct impact of the impact on the passenger compartment and greatly improving driving safety, but also ensures that the limiting component maintains an appropriate distance from the body skin 40. This ensures that the deformation of the crossbeam assembly 20 during a collision fully utilizes its energy-absorbing effect while being precisely controlled, avoiding unnecessary excessive deformation. This allows the vehicle structure to recover more easily after a collision, significantly reducing maintenance costs and optimizing the vehicle's maintenance economy and service life management.

[0053] In this embodiment, at least one of the first inclined beam assembly and the second inclined beam assembly includes: an inclined beam plate 203, which is set at a preset angle with the intermediate connecting plate 204, and the first end of the inclined beam plate 203 is connected to one end of the intermediate connecting plate 204 through a first arc-shaped transition plate 206; and an end beam plate 202, which is set at a preset angle with the inclined beam plate 203, and the first end of the end beam plate 202 is connected to the second end of the inclined beam plate 203 through a second arc-shaped transition plate 205. The end beam plate 202 and the inclined beam plate 203 are spaced apart, and the second end of the end beam plate 202 is movably connected to a limiting component.

[0054] By adopting this embodiment, the design of connecting the inclined beam plate 203, the intermediate connecting plate 204, and the end beam plate 202 at a preset angle and through an arc-shaped transition plate significantly improves the energy absorption efficiency and structural robustness of the anti-collision component.

[0055] Specifically, at least one of the first limiting sub-assembly 10 and the second limiting sub-assembly 30 includes: a limiting plate assembly connected to the subframe; a limiting post 102, one end of which is connected to the limiting plate assembly, the limiting post 102 being spaced apart from the subframe; an end beam plate 202 having a groove 201 extending along the length of the end beam plate 202; a portion of the limiting post 102 extending into the groove 201; and the end beam plate 202 being movably connected to the limiting post 102 and the limiting plate assembly respectively through the groove 201.

[0056] In this embodiment, the first limiting sub-assembly 10 and the second limiting sub-assembly 30, through their structural design including a limiting plate assembly and a limiting post 102, endow the anti-collision assembly with significant dynamic response advantages and self-resetting capabilities in collision events. One end of the limiting post 102 is securely connected to the limiting plate assembly, while the other end cleverly extends into a groove 201 on the end beam plate 202. This groove design allows the end beam plate 202 to slide in a controlled manner along its length under the action of the collision force, rather than being rigidly fixed, thereby effectively absorbing and dispersing collision energy and reducing permanent deformation of the beam assembly. More importantly, the end beam plate 202 can be reset to its initial position after a collision via the limiting post 102 within the groove 201, greatly simplifying the maintenance process and reducing maintenance costs.

[0057] In one exemplary embodiment, such as Figure 3 , Figure 4 and Figure 5As shown, the limiting plate assembly includes: a lateral limiting plate 103, the inner side of which is connected to the subframe, and the outer side of which is connected to one end of the limiting post 102; the lateral limiting plate 103 is movably connected to the end beam plate 202; a first vertical limiting plate 101, which is set at a preset angle to the lateral limiting plate 103; the first end of the first vertical limiting plate 101 is connected to the first end of the lateral limiting plate 103 by bolts 105; and a second vertical limiting plate 102. The limiting plate 104, the second vertical limiting plate 104 and the first vertical limiting plate 101 are spaced apart, the second vertical limiting plate 104 and the horizontal limiting plate 103 are set at a preset angle, the first end of the second vertical limiting plate 104 and the second end of the horizontal limiting plate 103 are connected by bolts 105; wherein, the first vertical limiting plate 101 and the second vertical limiting plate 104 are respectively movably connected to the end beam plate 202, and graphite powder 106 is provided between the end beam plate 202 and the horizontal limiting plate 103.

[0058] In this embodiment, a multi-dimensional limiting structure is formed by combining the lateral limiting plate 103 with the first vertical limiting plate 101 and the second vertical limiting plate 104, which significantly improves the stability and reset efficiency of the anti-collision system. The lateral limiting plate 103 is firmly connected between the subframe and the limiting post 102, which not only provides lateral limiting for the end beam plate 202 to ensure its orderly movement during a collision, but also achieves more comprehensive motion control of the end beam plate 202 through the preset angle setting with the first vertical limiting plate 101 and the second vertical limiting plate 104.

[0059] Further, at least one of the first vertical limiting plate 101 and the second vertical limiting plate 104 includes: a first connecting segment 107, which is arranged at a preset angle with the transverse limiting plate 103, and the first end of the first connecting segment 107 is connected to the first end of the transverse limiting plate 103; a second connecting segment 108, which is spaced apart from the transverse limiting plate 103, and is arranged at a preset angle with the first connecting segment 107, and one end of the second connecting segment 108 is connected to the second end of the first connecting segment 107; wherein at least one of the first connecting segment 107 and the second connecting segment 108 is movably connected to the end beam plate 202.

[0060] The first vertical limiting plate 101 and the second vertical limiting plate 104, through their unique two-section design—the first connecting section 107 and the second connecting section 108—significantly optimize the effectiveness and recovery mechanism of the vehicle's collision avoidance system. In this design, the first connecting section 107 is connected to the lateral limiting plate 103 at a specific angle, while the second connecting section 108 forms another preset angle with the first connecting section 107, ensuring the stability and flexibility of the structure. In particular, at least one of the first connecting section 107 and the second connecting section 108 is movably connected to the end beam plate 202, which means that under the action of collision force, the vertical limiting plate can adaptively deform as needed, effectively dispersing impact energy and protecting the main structure of the vehicle from serious damage.

[0061] In this embodiment, the crossbeam assembly 20 is made of an elastic material. The properties of the elastic material allow the crossbeam assembly 20 to deform rapidly upon impact, effectively absorbing and dispersing the impact force, and then automatically returning to its original shape after the external force is removed, avoiding the permanent deformation problem that is prone to occur with traditional rigid materials.

[0062] According to another specific embodiment of this application, a subframe is also provided, including: a subframe body; and a collision protection component, which is disposed on the outside of the subframe body and is the aforementioned collision protection component.

[0063] By applying this embodiment, by setting this innovative anti-collision component on the outside of the subframe body, when the vehicle is involved in a low-speed rear-end collision, it can effectively absorb and quickly release collision energy by means of the elastic materials and fine structural layout in the component, such as the first inclined beam component, the second inclined beam component and its limiting sub-components.

[0064] According to another specific embodiment of this application, a vehicle is also provided, including the aforementioned body components. By integrating a crossbeam assembly made of elastic material and a cleverly designed limiting plate structure, the vehicle exhibits excellent energy absorption performance and self-resetting capability in the face of low-speed collisions. This not only significantly improves the safety level of occupants in minor collisions and reduces permanent damage to the vehicle structure, but also greatly reduces maintenance costs and time, enhancing the vehicle's maintenance economy and ease of use.

[0065] In this embodiment, the vehicle includes: a main body with longitudinal beams; and a subframe fixed to and located below the longitudinal beams, the subframe being the same as described in the previous embodiment. The main body of the vehicle includes the crucial longitudinal beam structure, while the subframe is securely mounted below the longitudinal beams. The two work closely together to form the lower frame of the vehicle. Notably, the subframe employs the anti-collision component design described in the aforementioned embodiment. This design integrates a crossbeam assembly made of elastic material and an intelligent limiting plate assembly, significantly improving the vehicle's energy absorption capacity and self-repair efficiency during a collision.

[0066] When the anti-collision beam is impacted by a rear vehicle with a speed of v, the intrusion amount L = L1 + L2 + L3, where L1 is the distance between the vehicle body skin 40 and the beam assembly 20; L2 is the displacement of the beam assembly 20 due to elastic deformation during the collision; L3 is the end of the main beam's elastic deformation, at which point the locating pins on both sides of the fixing seats lock into the elongated holes of the main beam, and the rear vehicle further intrudes into the front vehicle, at which point the main beam undergoes plastic deformation. When L3 = 0, meaning the beam assembly 20 remains in elastic deformation throughout the collision, the anti-collision beam can recover after the impact and can still be reused.

[0067] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0068] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application.

Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this invention.
