Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a front bumper beam assembly and a vehicle. Background Technology

[0002] When a vehicle falls into water or wades through deep water, it typically sinks quickly, making occupant escape and vehicle rescue difficult. Some vehicles are equipped with buoyancy-enhancing modules to increase buoyancy in the water, providing more time and creating more favorable conditions for occupant escape and rescue. However, vehicles equipped with buoyancy-enhancing modules in the current may have the following technical problems: These modules are usually evenly distributed on the left and right sides of the vehicle. When the vehicle falls into water or wades through deep water, the front of the vehicle experiences greater impact from the water flow, and the vehicle's center of gravity is usually forward, leading to imbalance and a tendency for the front of the vehicle to sink, causing rapid loss of control. Furthermore, placing buoyancy-enhancing modules inside the vehicle may negatively impact its collision safety performance. Utility Model Content

[0017] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] like Figure 1 and Figure 2The front bumper beam assembly shown includes a front bumper beam body 1, an energy-absorbing box 3, and a buoyancy module group. The energy-absorbing box 3 is connected to the front bumper beam body 1. The buoyancy module group includes multiple first buoyancy modules 4 that are staggered from the energy-absorbing box 3 in the left-right direction. The multiple first buoyancy modules 4 are spaced apart in the left-right direction and are connected to the front bumper beam body 1 to increase the buoyancy of the front bumper beam assembly.

[0020] By using the aforementioned front bumper beam assembly, when the vehicle falls into water or wades in deep water, the first buoyancy module 4 can provide upward support force, increase the buoyancy of the front of the vehicle, and keep the vehicle as level or slowly tilting forward as possible, preventing the front of the vehicle from sinking and causing the vehicle to sink rapidly, thus providing more time for personnel to escape and for rescue operations.

[0021] In the aforementioned front bumper beam assembly, the buoyancy module group is set at the front bumper beam body 1 of the vehicle, making reasonable use of the arrangement space at the front bumper beam.

[0022] In the aforementioned front bumper beam assembly, the placement of each first buoyancy module 4 within the buoyancy module group is strategically designed. The first buoyancy modules 4 are staggered from the energy-absorbing box 3, ensuring that the energy-absorbing structure of the front bumper beam does not interfere with each other, thus balancing vehicle collision safety and water support functionality. The multiple first buoyancy modules 4 are spaced apart in the left-right direction, forming multi-point buoyancy support at the front bumper beam. This helps to ensure more uniform buoyancy support for the front of the vehicle, thereby ensuring a more stable posture for the front of the vehicle in water.

[0023] As a specific example, an energy-absorbing box 3 is connected to the left and right sides of the front bumper beam body 1, and the front end of the energy-absorbing box 3 is fixedly connected to the front bumper beam body 1.

[0024] In some embodiments, multiple first buoyancy modules 4 are detachably fixedly connected to the front bumper beam body 1. By adopting the above technical solution, the first buoyancy modules 4 are easy to replace, easy to maintain, and easy to customize. The first buoyancy modules 4 can be set as independent modules, allowing vehicle manufacturers to flexibly select and install the first buoyancy modules 4 according to differences in vehicle model configurations.

[0025] In practice, the first buoyancy module 4 can be detachably connected to the front anti-collision beam body 1 via buckles, slide rails or bolts 5.

[0026] In some embodiments, the first buoyancy module 4 includes a hollow, sealed outer shell. The sealed outer shell provides protection, ensuring that the first buoyancy module 4 can stably provide buoyancy, forming a stable buoyancy source and reducing the possibility of failure of the first buoyancy module 4. In specific implementations, the sealed outer shell can be made of plastic or airtight foam material.

[0027] In some embodiments, the first buoyancy module 4 further includes a low-density filler material filling the inner cavity of the sealed housing. The low-density filler material provides support for the sealed housing, ensuring the buoyancy of the first buoyancy module 4 while reducing the possibility of failure of the first buoyancy module 4. In specific implementations, the low-density filler material can be foam.

[0028] The first buoyancy module 4 described above has the characteristics of small structural size and light weight, and has almost no impact on the front weight distribution of the vehicle.

[0029] In some embodiments, a first buoyancy module 4 is connected to each end of the front bumper beam body 1. By placing the first buoyancy module 4 at both ends of the front bumper beam body 1, the energy-absorbing parts of the front bumper beam body 1 can be avoided, as well as sensors and radars near the front bumper beam body 1.

[0030] In some embodiments, a front bumper beam body 1 is provided with a bumper beam cavity 2, and the buoyancy module assembly is located inside the bumper beam cavity 2. By placing the buoyancy module assembly inside the bumper beam cavity 2, the internal space of the front bumper beam body 1 is utilized efficiently, and the buoyancy module assembly does not occupy the arrangement space on the outside of the bumper beam body.

[0031] In some embodiments, the front bumper beam body 1 is provided with multiple bumper beam cavities 2 that are spaced apart from each other in the vertical direction, and each of the multiple bumper beam cavities 2 is provided with a buoyancy module group. Providing multiple bumper beam cavities 2 that are spaced apart from each other in the vertical direction within the front bumper beam body 1 can improve the structural performance of the front bumper beam body 1. The buoyancy module groups within the multiple bumper beam cavities 2 can better form multi-point buoyancy support.

[0032] In practice, the front bumper beam body 1 can be made of metal materials such as aluminum alloy or steel plate. The inner cavity 2 of the bumper beam is arranged along the length of the front bumper beam body 1, and the left and right ends of the inner cavity 2 of the bumper beam pass through the left and right ends of the front bumper beam body 1.

[0033] In some embodiments, a plurality of first buoyancy modules 4 are connected to the rear sidewall of the front bumper beam body 1. By placing the first buoyancy modules 4 on the rear sidewall of the front bumper beam body 1, the first buoyancy modules 4 have a relatively small impact on the collision performance of the front bumper beam body 1.

[0034] This utility model also proposes a vehicle including the front bumper beam assembly described in any of the above claims.

[0035] In some embodiments, a plurality of second buoyancy modules are provided in the sill beam of the vehicle at intervals in the longitudinal direction to increase the buoyancy of the sill beam. Using the above technical solution, the plurality of first buoyancy modules 4 of the front bumper beam assembly and the plurality of second buoyancy modules in the two sill beams can better form multi-point buoyancy support, providing a more uniform and stable buoyancy support force for vehicles that have fallen into water or are wading through deep water.
