Description

Technical Field

[0001] The present application relates to the technical field of automobiles, and particularly to a vehicle front floor skeleton structure and a vehicle. Background Art

[0002] At present, the frequency of traffic accidents is very high, often causing casualties. Among the reasons for traffic accidents to cause harm to drivers and passengers, the most common one is that the collision causes the deformation of the occupant compartment. As one of the important components of the occupant compartment, the front floor structure is one of the key force transmission paths for side collisions and frontal collisions of the whole vehicle, and is an important part to ensure the safety of the cockpit. Therefore, the front floor structure plays a crucial role in protecting the safety of drivers and passengers.

[0003] At present, in order to increase the stiffness and strength of the front floor, reduce the impact of collisions on the occupant compartment, and protect the safety of drivers and passengers, complex front seat crossbeams and their reinforcement members are adopted on the front floor, and at the same time, complex front floor reinforcement members are also used. The common front floor skeleton beams of automobile bodies are in a "field" structure and an "eye" structure. However, the stiffness and strength of these two structures are still difficult to meet the safety requirements of the vehicle body. When a collision occurs, the floor is easily separated from the sill beam, seat crossbeam, etc., resulting in the loss of support of the floor and serious wrinkling and deformation of itself, threatening personal safety. Utility Model Content

[0004] Based on this, the present utility model provides a vehicle front floor skeleton structure and a vehicle to solve the problem that when a vehicle collides, structural beams such as the sill beam and seat crossbeam are easily separated from the floor, resulting in the loss of support of the floor and serious wrinkling and deformation of itself, threatening personal safety.

[0005] On the one hand, a vehicle front floor skeleton structure provided by the present utility model includes:

[0006] A skeleton body, which includes two sill beams, a seat crossbeam horizontally connected between the two sill beams, and a middle channel assembly longitudinally connected to the seat crossbeam and located between the two sill beams;

[0007] A first reinforcement assembly, which includes two reinforcement beam members respectively connected between the two sill beams and both sides of the middle channel assembly;

[0008] A second reinforcement assembly, which includes a reinforcement filling member filled in the cavity of the middle channel assembly, and the reinforcement filling member at least fills the cavity at one end of the middle channel assembly connected to the seat crossbeam.

[0009] In one embodiment, each of the reinforcement beam members includes at least one reinforcement crossbeam horizontally connected between the sill beam and the middle channel assembly and at least one reinforcement longitudinal beam longitudinally connected to the seat crossbeam and the reinforcement crossbeam.

[0010] In one embodiment, the reinforcing cross beams of the two reinforcing beam members are arranged opposite to each other.

[0011] In one embodiment, each of the reinforcing cross beams transversely penetrates the reinforcing longitudinal beam connected thereto.

[0012] In one embodiment, each of the reinforcing longitudinal beams is located at a central position between the middle channel assembly and the sill beam connected thereto.

[0013] In one embodiment, the middle channel assembly is located at a central position between the two sill beams.

[0014] In one embodiment, both the reinforcing cross beam and the reinforcing longitudinal beam are sheet metal cavity parts.

[0015] In one embodiment, the reinforcing filler extends at least from the end of the middle channel assembly connected to the seat cross beam to the position where the middle channel assembly is connected to the reinforcing cross beam.

[0016] In one embodiment, the reinforcing filler is a CBS filler.

[0017] On the other hand, the vehicle provided by the present invention includes the vehicle front floor skeleton structure of any one of the above embodiments.

[0018] The present invention has at least the following beneficial effects compared with the prior art:

[0019] In the above vehicle front floor skeleton structure, by filling a reinforcing filler in the cavity at the end of the middle channel assembly connected to the seat cross beam, the structural strength of the connection part between the middle channel assembly and the seat cross beam is enhanced, so that the strength under the vehicle seat is relatively large, and the anti-frontal collision ability of the front floor is improved. When a frontal collision occurs, the middle area of the vehicle front floor will deform first, while the connection part between the middle channel assembly and the seat cross beam will not undergo large collapse, so that the deformation at the seat is minimized, thereby protecting the safety of the driver and passengers. And by respectively arranging reinforcing beam members between the two sill beams and both sides of the middle channel assembly, when a collision occurs, the reinforcing beam members can provide stress points on both sides of the middle channel assembly, enhance the overall structural strength of the skeleton, and disperse the stress points of the skeleton, avoiding the rapid detachment of the seat cross beam and the sill beam. Moreover, the two reinforcing beam members are beneficial to uniform stress and improve the mechanical properties of the vehicle front floor. Description of the Drawings

[0028] In the existing front floor skeleton, when a vehicle collides, structural beams such as the sill beam and the seat crossbeam are prone to fall off from the floor, resulting in the floor losing support and severely wrinkling and deforming itself, threatening personal safety.

[0029] Based on this, the embodiment of the present utility model provides a vehicle front floor skeleton structure, which includes:

[0030] A skeleton body, which includes two sill beams 1, a seat crossbeam 2 transversely connected between the two sill beams 1, and a center tunnel assembly 3 longitudinally connected to the seat crossbeam 2 and located between the two sill beams 1;

[0031] A first strengthening component, which includes two strengthening beam members 4 respectively connected between the two sill beams 1 and both sides of the center tunnel assembly 3;

[0032] A second strengthening component, which includes a strengthening filler 5 filled in the cavity of the center tunnel assembly 3, and the strengthening filler 5 at least fills the cavity at one end of the center tunnel assembly 3 connected to the seat crossbeam 2.

[0033] According to the front floor skeleton structure provided by the embodiment of the present invention, the strengthening filler 5 is filled in the cavity at the end where the center tunnel assembly 3 is connected to the seat crossbeam 2, strengthening the structural strength of the connection part between the center tunnel assembly 3 and the seat crossbeam 2, making the strength under the vehicle seat relatively large, improving the anti-frontal collision ability of the front floor. When a frontal collision occurs, the middle area of the vehicle front floor will deform first, while the connection part between the center tunnel assembly 3 and the seat crossbeam 2 will not undergo large collapse, so that the deformation at the seat is minimized, thereby protecting the safety of the driver and passengers. By respectively arranging the strengthening beam members 4 between the two sill beams 1 and the center tunnel assembly 3, when a collision occurs, the strengthening beam members 4 can provide stress points on both sides of the center tunnel assembly 3, strengthening the overall structural strength of the skeleton and dispersing the stress points of the skeleton, preventing the seat crossbeam 2 and the sill beam 1 from falling off quickly, and the two strengthening beam members 4 are beneficial to uniform stress, improving the mechanical properties of the vehicle front floor.

[0034] The vehicle front floor skeleton structure provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] According to Figure 1 Exemplarily showing the vehicle front floor skeleton structure of at least one implementation manner of the present invention, the vehicle front floor skeleton structure includes: a skeleton body and a strengthening component.

[0036] In this embodiment, the skeleton body is the main part of the front floor skeleton structure, used to support the vehicle body and enhance the structural strength of the vehicle body.

[0037] Specifically, referring to Figure 1 , the skeleton body includes a sill beam 1, a seat crossbeam 2, and a center tunnel assembly 3. The sill beam 1, the seat crossbeam 2, and the center tunnel assembly 3 are connected in a specified arrangement to form a skeleton structure, thereby strengthening the strength of the vehicle chassis.

[0038] It can be understood that in this embodiment, the individual structures of the sill beam 1, the center tunnel assembly 3, and the seat crossbeam 2 are all conventional existing technologies. Therefore, the specific structures thereof will not be elaborated in this embodiment, and only the arrangement and connection relationships among the components will be described below.

[0039] Referring to Figure 1 , in this embodiment, there are two sill beams 1, and the two sill beams 1 are respectively arranged on the left and right sides of the skeleton body, corresponding to the left and right sides of the vehicle front floor. Moreover, both sill beams 1 extend in the longitudinal direction, so that the two sill beams 1 are arranged parallel to each other left and right, matching the vehicle body structure. These two sill beams 1 can effectively disperse the impact force received during a vehicle side collision, thereby reducing the deformation of the vehicle front floor and reducing the harm to the passengers inside the vehicle.

[0040] In this embodiment, there is one seat crossbeam 2, which is used to install the vehicle seat and provide support for the vehicle seat. Specifically, corresponding to the vehicle front floor skeleton structure provided in this embodiment, this seat crossbeam 2 is the front seat crossbeam and is used to install the front seat of the vehicle. Specifically, referring to Figure 1 , in this embodiment, the seat crossbeam 2 is transversely connected between the two sill beams 1, and the seat crossbeam 2 is perpendicular to the sill beams 1 on both sides.

[0041] In this embodiment, the center tunnel assembly 3 is used to be installed on the vehicle front floor in the longitudinal direction, for providing support and transmitting collision energy, and strengthening the anti-collision performance of the vehicle. Specifically, referring to Figure 1 , in this embodiment, the center tunnel assembly 3 is longitudinally connected to the seat crossbeam 2. Specifically, the rear end of the center tunnel assembly 3 is fixedly connected to the seat crossbeam 2, and the center tunnel assembly 3 is located between the two sill beams 1.

[0042] Furthermore, referring to Figure 1 , in this embodiment, the center tunnel assembly 3 is arranged parallel to the two sill beams 1, that is, the center tunnel assembly 3 is arranged perpendicular to the seat crossbeam 2, and the center tunnel assembly 3 is located at the middle position between the two sill beams 1. With such an arrangement, the components of the skeleton body are evenly distributed, the force balance of the skeleton body is better, and the stability and safety of the vehicle are improved.

[0043] Based on the above structural design, the center tunnel assembly 3, the seat crossbeam 2, and the sill beams 1 on both sides are connected to each other to form the skeleton body of this embodiment, constituting the main part of the vehicle front floor skeleton structure, and can achieve the effects of supporting the vehicle body and enhancing the structural strength of the vehicle body.

[0044] In this embodiment, the strengthening component is an additional part of the front floor skeleton structure, which is used to improve the connection strength and support strength between the components of the skeleton body, so as to further strengthen the structural strength of the vehicle front floor skeleton structure and enhance the anti-collision performance of the front floor.

[0045] Specifically, refer to Figure 3 , in this embodiment, the strengthening component specifically includes a first strengthening component and a second strengthening component.

[0046] Among them, the first strengthening component is connected between the sill beam 1 and the middle channel assembly 3, which is used to improve the connection strength between the seat cross beam 2 and the sill beam 1, prevent the seat cross beam 2 and the sill beam 1 from falling off during a collision, improve the structural strength of the skeleton structure, disperse the stress points of the skeleton, make the overall force of the skeleton structure more uniform, and improve the mechanical properties of the vehicle front floor.

[0047] Specifically, refer to Figure 1 , the first strengthening component includes two strengthening beam members 4, and the two strengthening beam members 4 are respectively arranged between the two sides of the middle channel assembly 3 and the two sill beams 1. Each strengthening beam member 4 includes a strengthening cross beam 401 and a strengthening longitudinal beam 402. Among them, the strengthening cross beam 401 is transversely connected between the sill beam 1 and the middle channel assembly 3, and the strengthening longitudinal beam 402 is longitudinally connected to the seat cross beam 2 and the strengthening cross beam 401. With such a setting, the strengthening cross beam 401 and the strengthening longitudinal beam 402 are arranged in a cross shape. Through the strengthening longitudinal beam 402, the anti-collision performance of the front floor in the longitudinal direction can be improved, and through the strengthening cross beam 401, the anti-collision performance of the front floor in the transverse direction can be improved. The combination of the two improves the ability of the front floor to resist frontal collision and side collision, prevents the seat cross beam 2 and the sill beam 1 from falling off quickly during a collision, and improves the structural strength of the skeleton structure.

[0048] Refer to Figure 1 , in this embodiment, it only exemplarily shows an implementation manner in which the strengthening beam member 4 includes one strengthening cross beam 401 and one strengthening longitudinal beam 402. However, in actual use, it is not limited to this. For example, in some other embodiments, the number of the strengthening cross beam 401 and the strengthening longitudinal beam 402 of the strengthening beam member 4 can also be two or more. By setting multiple strengthening cross beams 401 and strengthening longitudinal beams 402, the connection strength and structural strength of the skeleton structure can be enhanced, so as to achieve the purpose of enhancing the anti-collision performance of the vehicle front floor.

[0049] For example, refer to Figure 1, in this embodiment, preferably, the number of the longitudinal reinforcing beams 402 in each reinforcing beam member 4 is one, and the longitudinal reinforcing beam 402 is located at the middle position between the middle channel assembly 3 and the sill beam 1 connected thereto. With such a setting, the longitudinal reinforcing beam 402 plays a role in strengthening the front floor at the middle position between the middle channel assembly 3 and the sill beam 1. It is evenly distributed with the middle channel assembly 3 and the sill beam 1 in the left-right direction of the vehicle, which can make the force on the frame structure more uniform and the strengthening effect more obvious. Moreover, a single longitudinal reinforcing beam 402 can also achieve lightweight design while ensuring the connection strength.

[0050] For example, refer to Figure 1 , in this embodiment, preferably, the number of the transverse reinforcing beams 401 in each reinforcing beam member 4 is also one, and the transverse reinforcing beams 401 of the two reinforcing beam members 4 are arranged transversely opposite to each other. With such a setting, the two transverse reinforcing beams 401 are directly opposite in the left-right direction of the vehicle, which can form a force transmission path in the left-right direction of the front floor, make the force more uniform, improve the structural strength of the front floor frame structure, and have better anti-collision performance. Similarly, a single transverse reinforcing beam 401 can also achieve lightweight design while ensuring the connection strength.

[0051] Furthermore, refer to Figure 1 and Figure 3 , in this embodiment, each transverse reinforcing beam 401 transversely penetrates through the longitudinal reinforcing beam 402 connected thereto. With such a setting, the transverse reinforcing beam 401 has a left-right through structure, its own structural strength is better, and the strengthening effect is more obvious, ensuring the anti-collision performance of the front floor.

[0052] Furthermore, in this embodiment, each transverse reinforcing beam 401 and longitudinal reinforcing beam 402 are sheet metal cavity parts. With such a setting, during a collision, the cavity structure of the reinforcing beam can effectively disperse and absorb the collision energy, reduce the damage of the vehicle body structure, have a better effect on stabilizing the floor deformation, thereby providing more protection for the occupants, and at the same time can achieve lightweight design.

[0053] In this embodiment, the second reinforcing component is arranged in the cavity of the middle channel assembly 3 near one end of the seat cross beam 2 and is connected to the seat cross beam 2, which is used to improve the strength of the part where the middle channel assembly 3 is connected to the seat cross beam 2, avoid the middle channel assembly 3 collapsing to the seat cross beam 2 during a collision, thereby ensuring that the deformation generated at the seat during a frontal collision of the vehicle is small and protecting the safety of the driver and passengers.

[0054] Specifically, refer to Figure 2 and Figure 3, in this embodiment, the second strengthening component includes a strengthening filler 5. The strengthening filler 5 is filled in the cavity of the middle channel assembly 3, and the strengthening filler 5 at least fills the cavity at one end of the middle channel assembly 3 that is connected to the seat crossbeam 2. With such a setting, the structural strength of the connection part between the middle channel assembly 3 and the seat crossbeam 2 can be strengthened by the strengthening filler 5. During a frontal collision, the middle area of the vehicle front floor will deform first, while the connection part between the middle channel assembly 3 and the seat crossbeam 2 will not undergo significant collapse, so that the deformation at the seat is minimized, improving the frontal collision resistance of the front floor and thus protecting the safety of the driver and passengers.

[0055] More specifically, referring to Figure 2 and Figure 3 , in this embodiment, the strengthening filler 5 is a solid part that matches the cavity contour of the middle channel assembly 3, enabling it to fit completely in the cavity of the middle channel assembly 3 and fill the cavity, ensuring the structural strength at the end of the middle channel assembly 3. For example, in this embodiment, the strengthening filler 5 can specifically be a CBS (Composite Body Solutions) filler. Filling the CBS composite material into the cavity of the middle channel assembly 3 can form a highly stable and strong filler, which plays a positive role in improving the structural strength and durability of the connection end between the middle channel assembly 3 and the seat crossbeam 2, ensuring that there is no significant collapse at the connection part between the middle channel assembly 3 and the seat crossbeam 2 and enhancing the frontal collision resistance of the front floor.

[0056] Furthermore, referring to Figure 2 and Figure 3 , in this embodiment, the strengthening filler 5 extends from at least the end of the middle channel assembly 3 connected to the seat crossbeam 2 to the position where the middle channel assembly 3 is connected to the strengthening crossbeam 401. With such a setting, the structural strengthening range provided by the strengthening filler 5 for the middle channel assembly 3 covers the connection part between the middle channel assembly 3 and the strengthening crossbeam 401, ensuring that there is no significant collapse at the connection part between the middle channel assembly 3 and the strengthening crossbeam 401 during a collision, preventing the strengthening crossbeam 401 from shifting significantly, so that it can maintain its strengthening characteristics for the skeleton structure and ensuring the overall structural strength of the front floor skeleton structure.

[0057] It can be understood that the left - right direction and the transverse direction mentioned above in this embodiment can be understood as the left - right direction of the whole vehicle, and the front - rear direction and the longitudinal direction can be understood as the front - rear direction of the whole vehicle. The fixed connection methods between the components involved in this embodiment are all welding.

[0058] On the other hand, the embodiment of the present utility model also provides a vehicle, which includes the above - mentioned vehicle front floor skeleton structure.

[0059] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0060] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
