[0032] Please also read Figures 1 to 11 The sill beam reinforcement structure and the vehicle provided by the utility model are now described. The sill beam reinforcement structure includes a support plate 1, a reinforcement plate 2 and an energy absorbing bracket 3. The support plate 1 is connected to the inner side of the side reinforcement plate 7 along the front-to-back direction. The energy absorbing bracket 3 is connected to the inner side of the side reinforcement plate 7. The energy absorbing bracket 3 is supported below the reinforcement plate 2. The reinforcement plate 2 has a reinforcement boss 4 protruding upward. A plurality of reinforcement bosses 4 are provided at intervals along the front-to-back direction.
[0033] Compared with the prior art, the sill beam reinforcement structure provided in the present embodiment utilizes the support plate 1 connected to the side reinforcement plate 7 to effectively support the reinforcement plate 2. Combined with the arrangement of the reinforcement boss 4, the ability of the door frame beam to resist deformation is effectively enhanced, and the structural strength of the sill beam is improved. The energy-absorbing bracket 3 arranged below the support plate 1 can, on the one hand, support the support plate 1, and on the other hand, can produce a crushing deformation when the vehicle is hit sideways, thereby forming a crushing energy-absorbing effect, which can reduce the impact force acting on the driver and passengers and improve the safety of the vehicle during driving.
[0034] In this embodiment, the support plate 1 is supported below the reinforcing plate 2, and the outer edge of the support plate 1 is connected to the side reinforcement plate 7, so as to form a supporting effect on the reinforcing plate 2. The reinforcing boss 4 provided on the reinforcing plate 2 can effectively enhance the structural strength of the reinforcing plate 2, so as to enhance the ability of the vehicle body to resist deformation in the up-down direction and the left-right direction.
[0035] The energy absorbing bracket 3 is located below the support plate 1, the lower part of the energy absorbing bracket 3 is connected to the lower edge of the side reinforcement plate 7, and the upper part of the energy absorbing bracket 3 is supported below the support plate 1. It can cooperate with the support plate 1 and the reinforcement plate 2 to enhance the supporting effect in the up and down directions, and play an effective structural reinforcement effect.
[0036] On this basis, the energy absorbing bracket 3 can also collapse and deform when the vehicle has a side collision, so that the deformation position is close to the lower edge of the side reinforcement plate 7, that is, close to the position of the vehicle chassis, thereby avoiding excessive impact on the drivers and passengers in the vehicle and improving the safety of the drivers and passengers.
[0037] In some possible implementations, the above-mentioned characteristic reinforcement plate 2 is adopted as follows Figures 7 to 9 See the structure shown. Figures 7 to 9 A reinforcing plate 5 is also provided above the reinforcing plate 2 , and the reinforcing plate 5 is connected to the top surface of the reinforcing boss 4 . The outer edge of the reinforcing plate 5 has a downwardly bent connecting strip 51 , and the connecting strip 51 is connected to the inner wall of the side reinforcement plate 7 .
[0038] In this embodiment, while the support plate 1 is used to support the reinforcement plate 2, a reinforcement plate 5 is also arranged on the top of the reinforcement plate 2. The reinforcement plate 5, the reinforcement plate 2 and the support plate 1 all extend in the front-to-back direction, and the three effectively correspond to each other in the up-down direction, forming a three-layer laminated reinforcement structure, thereby ensuring the structural reinforcement effect of the door sill beam. The selection of the above-mentioned laminated reinforcement structure can be selected according to different collision standards of different models, and has good practicality.
[0039] On this basis, the outer edge of the reinforcing plate 5 is connected to the side reinforcement plate 7 through the connecting strip 51, and the outer wall of the connecting strip 51 and the inner wall of the side reinforcement plate 7 can be connected by welding, bonding and other methods, which is convenient for connecting the reinforcing plate 2 to the side reinforcement plate 7, improves the reliability of the structural connection, and ensures the structural reinforcement effect of the reinforcing plate 2 on the sill beam.
[0040] At the same time, in order to further enhance the strength of the reinforcing plate 5, an upwardly protruding reinforcing rib 52 is provided on the top surface of the reinforcing plate 5. The reinforcing rib 52 extends in the same direction as the reinforcing plate 5, that is, extends along the front-rear direction of the vehicle body, which can play a good role in structural reinforcement.
[0041] As a parallel embodiment, the above-mentioned characteristic reinforcing plate 2 adopts Figure 10 to Figure 11 See the structure shown. Figure 10 to Figure 11 The reinforcing plate 2 is connected to the inner wall of the side reinforcement plate 7 through a reinforcing bracket 6. The reinforcing bracket 6 is located between two adjacent reinforcing bosses 4 and is connected to the two reinforcing bosses 4 respectively.
[0042] In this embodiment, the reinforcing plate 2 is connected to the side reinforcement plate 7 through the reinforcing bracket 6, and the reinforcing plate 5 can be omitted. The reinforcing bracket 6 is located between two adjacent reinforcing bosses 4, and the space between the two reinforcing bosses 4 can be fully utilized for the installation and layout of the structure.
[0043] The front and rear side edges of the reinforcing bracket 6 are respectively connected to the corresponding side walls of the two adjacent reinforcing bosses 4, and the outer edge of the reinforcing bracket 6 is connected to the inner wall of the side reinforcement plate 7, so that a reliable connection is formed between the reinforcing bracket 6 and the side reinforcement plate 7, ensuring the reliability of the installation position of the reinforcing plate 2.
[0044] On this basis, the reinforcing bracket 6 is provided with a weight-reducing hole 63 which passes through from top to bottom, so as to reduce the material consumption while ensuring the reliable connection between the reinforcing plate 2 and the side reinforcement plate 7, and also meet the requirements of lightweight design.
[0045] In some embodiments, the above-mentioned feature reinforcement bracket 6 can be used as follows Figure 6 See the structure shown. Figure 6 The front and rear side edges of the reinforcing bracket 6 both have a first connecting portion 61, and the two first connecting portions 61 are connected to two adjacent reinforcing bosses 4 one by one. The outer edge of the reinforcing bracket 6 has a second connecting portion 62, and the second connecting portion 62 is connected to the inner wall of the side reinforcement plate 7.
[0046] In this embodiment, the first connecting portion 61 on the reinforcing bracket 6 can contact and connect with the front side wall or the rear side wall of the reinforcing boss 4, and different connection methods such as welding or bonding can be adopted, which can effectively increase the connection area between the reinforcing bracket 6 and the side reinforcement plate 7.
[0047] Specifically, the two first connection portions 61 may both be formed by bending upward, or both be formed by bending downward, or one of them may be bent upward and the other may be bent downward.
[0048] At the same time, the reinforcing bracket 6 can be used to form a support effect in the front-to-rear direction between two adjacent reinforcing bosses 4, thereby enhancing the vehicle's ability to resist deformation in the front-to-rear direction, ensuring the stability of the relative positions between multiple reinforcing bosses 4, and facilitating the formation of a reliable reinforcement structure.
[0049] On this basis, the outer edge of the reinforcing bracket 6 is further provided with a second connecting portion 62, which extends upward and can be connected to the inner wall of the side reinforcement plate 7 by welding or bonding, which can effectively increase the contact area and improve the reliability of the connection. The second connecting portion 62 can be formed in the form of bending upward or bending downward.
[0050] In some possible implementations, the above-mentioned feature reinforcement boss 4 is adopted as follows Figure 10 to Figure 11 See the structure shown. Figure 10 to Figure 11 An arc portion 41 extending in the left-right direction is provided on the top surface of the reinforcing boss 4, the middle part of the arc portion 41 is convex upward, and a concave strip 42 is also provided on the arc portion 41, and the concave strip 42 extends in the left-right direction.
[0051] In this embodiment, an arcuate portion 41 is provided on the top of the reinforcing boss 4 to form an arch structure on the top of the reinforcing boss 4. The arcuate portion 41 extends along the left-right direction of the vehicle body, and the middle portion is arc-shaped and convex upward, which helps to improve the supporting performance of the reinforcing boss 4 in the left-right direction of the vehicle body, so that the reinforcing plate 2 has a better ability to resist deformation.
[0052] On the basis of the above structure, by providing an inner concave strip 42 on the arc-shaped portion 41, the entire top surface of the reinforcing boss 4 forms an uneven reinforcing structure, which further improves the overall strength of the structure and effectively enhances the ability of the threshold beam to resist deformation.
[0053] Specifically, the extension direction of the inner concave strip 42 is consistent with the extension direction of the arc portion 41, and the depth of the inner concave strip 42 in the inner cavity of the arc portion 41 remains consistent, so that the arc portion 41 can be structurally reinforced at all locations in the left and right directions of the vehicle body and has higher structural strength.
[0054] In some possible implementations, the above-mentioned characteristic support plate 1 is adopted as follows Figures 2 to 3 See the structure shown. Figures 2 to 3 The support plate 1 is provided with an upper convex strip 11 which is protruding upward, and the bottom surface of the reinforcing plate 2 is provided with a limiting groove 21 which cooperates with the upper convex strip 11. The upper convex strip 11 and the limiting groove 21 extend along the front and rear directions of the vehicle body respectively.
[0055] In this embodiment, the upper convex strip 11 on the support plate 1 can improve the structural strength of the support plate 1 without increasing the material consumption of the support plate 1, and the limiting groove 21 on the bottom surface of the reinforcement plate 2 can increase the structural strength of the reinforcement plate 2 without increasing the material consumption of the reinforcement plate 2, thereby meeting their respective structural reinforcement performances.
[0056] On this basis, the upper convex strip 11 and the limiting groove 21 extend along the front-rear direction of the vehicle body respectively, and the two cooperate with each other to limit the relative positions of the support plate 1 and the reinforcing plate 2 in the left-right direction of the vehicle body for subsequent assembly.
[0057] In some possible implementations, the characteristic energy absorbing bracket 3 is as follows: Figure 5 See the structure shown. Figure 5 The energy absorbing bracket 3 includes a side vertical plate 31 connected to the side reinforcement plate 7 and a supporting plate 32 connected to the top of the side vertical plate 31. The top surface of the supporting plate 32 is connected to the bottom surface of the support plate 1. The side vertical plate 31 is provided with a collapse hole 34.
[0058] In this embodiment, the energy absorbing bracket 3 is formed by combining a side vertical plate 31 and a supporting plate 32 to form a component approximately inverted L-shaped. The supporting plate 32 is supported below the supporting plate 1, and the lower part of the side vertical plate 31 is connected to the inner wall of the lower edge of the side reinforcement plate 7 to support the supporting plate 1. The collapse holes 34 provided on the side vertical plate 31 facilitate the collapse deformation of the energy absorbing bracket 3 when it is subjected to a collision, thereby achieving a good collapse energy absorption effect and improving the safety of the driver and passengers.
[0059] In some embodiments, the above-mentioned characteristic energy absorbing bracket 3 can be used as follows Figure 5 See the structure shown. Figure 5 The front and rear side edges of the energy absorbing bracket 3 are respectively connected with support ribs 33 , which are connected to the inner side of the side upright plate 31 and extend upward to be connected to the bottom surface of the supporting plate 32 .
[0060] In the present embodiment, the support ribs 33 arranged at the front and rear side edges of the energy absorbing bracket 3 can be an integrally formed structure or a separately formed structure with the energy absorbing bracket 3, and the connection portion between the support plate 32 and the side vertical plate 31 can be strengthened to achieve a supporting effect on the upper support plate 32, thereby ensuring the structural strength of the energy absorbing bracket 3, and helping to increase the crushing energy absorption effect of the energy absorbing bracket 3, so as to facilitate the generation of crushing energy absorption when the vehicle has a side collision, meet the standard requirements for vehicle collision, and improve the safety of the vehicle during driving.
[0061] In some embodiments, the above-mentioned characteristic side stand 31 can be adopted as follows Figure 5 See the structure shown. Figure 5The lower width of the side plate 31 is smaller than the upper width of the side plate 31, and the collapse hole 34 is provided at the upper part of the side plate 31. In order to make the energy absorbing bracket 3 have a collapse deformation effect, the lower width of the side plate 31 is set to be smaller than the upper width of the side plate 31, thereby improving the collapse energy absorption performance of the energy absorbing bracket 3 and improving the safety during driving.
[0062] Based on the same inventive concept, the embodiment of the present application also provides a vehicle, which includes a sill beam reinforcement structure. The vehicle uses a support plate 1 connected to a side reinforcement plate 7 to effectively support a reinforcement plate 2, and combined with the arrangement of a reinforcement boss 4, the ability of the sill beam to resist deformation can be effectively enhanced, and the structural strength of the sill beam can be improved. The energy absorbing bracket 3 arranged below the support plate 1 can, on the one hand, support the support plate 1, and on the other hand, can produce a crushing deformation when the vehicle is hit from the side, forming a crushing energy absorbing effect, which can reduce the impact force acting on the driver and passengers, and improve the safety of the vehicle during driving.
