Description

Technical Field

[0001] This application relates to the technical field of vehicles, and more specifically, to a door sill assembly and a vehicle. Background Technology

[0002] As the automotive industry continues to develop, consumers are demanding higher and higher standards for vehicle collision safety. When a vehicle is involved in a side pole collision, the pole impacts and compresses the sill. If the sill beam's impact and bending resistance are insufficient, it can lead to excessive B-pillar intrusion, tearing at the base of the B-pillar, tearing at the joint between the B-pillar and the upper side beam, and other structural failures of key components. This can compress the survival space inside the passenger compartment, threatening the lives of the occupants, and can also compress the battery pack, posing a significant safety hazard.

[0003] Currently, to improve the side pole impact resistance of vehicles, the methods of increasing the thickness of the sill beam and increasing the cross-sectional size of the sill beam are often used to improve the impact resistance. These methods increase the stiffness of the sill beam to a certain extent, but they also significantly increase the cost and vehicle weight, which is not conducive to the overall vehicle lightweighting.

[0004] There is currently no good solution to the technical problem of improving the side pole impact resistance of a vehicle while taking into account the overall lightweight design. Utility Model Content

[0005] This application provides a door sill assembly and a vehicle to at least solve the technical problem of how to improve the side pole impact resistance of a vehicle while taking into account the overall lightweight design of the vehicle.

[0006] According to one aspect of the embodiments of this application, a door sill assembly is provided, comprising: a door sill beam having a first receiving cavity and a B-pillar mounting position, the first receiving cavity extending along the length direction of the door sill beam; a reinforcing beam having a second receiving cavity extending along the length direction of the door sill beam and disposed within the first receiving cavity and connected to the door sill beam; and a reinforcing structure having a second receiving cavity extending along the length direction of the door sill beam and connected to the reinforcing beam, the reinforcing structure spanning the B-pillar mounting position along the length direction of the door sill beam.

[0007] Furthermore, the sill beam includes an outer sill plate and an inner sill plate, with a first receiving cavity formed between the outer sill plate and the inner sill plate, and a reinforcing structure is set close to the outer sill plate.

[0008] Furthermore, the second receiving cavity is provided with two reinforcing ribs, which are spaced apart along the width direction of the reinforcing beam. The two reinforcing ribs divide the second receiving cavity into a first chamber, a second chamber, and a third chamber. The third chamber is located near the outer panel of the threshold, and the reinforcing structure is located inside the third chamber.

[0009] Furthermore, the reinforcing structure is a tubular structure, with its outer wall fitting snugly against the inner wall of the third chamber.

[0010] Furthermore, the reinforcing beam is located in the middle of the first receiving cavity, and the reinforcing beam divides the first receiving cavity into a fourth chamber and a fifth chamber, which are spaced apart along the height direction of the threshold beam.

[0011] Furthermore, the reinforcing beam has a first sidewall and a second sidewall disposed opposite to each other, the first sidewall being disposed near the outer sill plate and the second sidewall being disposed near the inner sill plate, the first sidewall being connected to the outer sill plate and / or the second sidewall being connected to the inner sill plate.

[0012] Furthermore, the top wall of the reinforcing beam is connected to the outer and inner sill plates of the sill via a first connector, and the bottom wall of the reinforcing beam is connected to the outer and inner sill plates of the sill via a second connector.

[0013] Furthermore, a first flange is provided at the edge of the outer sill plate, and a second flange is provided at the edge of the inner sill plate. The first flange and the second flange are arranged opposite to each other along the Y direction of the vehicle body. One end of the first connector is connected to the upper surface of the reinforcing beam, and the other end of the first connector extends upward to connect with the first flange and the second flange. One end of the second connector is connected to the lower surface of the reinforcing beam, and the other end of the second connector extends downward to connect with the first flange and the second flange.

[0014] Furthermore, the first connector is an L-shaped plate or a T-shaped plate, and / or the second connector is an L-shaped plate or a T-shaped plate.

[0015] According to another aspect of the embodiments of this application, a vehicle is also provided, the vehicle including the above-described sill assembly.

[0016] In this embodiment, a reinforcing beam is disposed within a first receiving cavity of the sill beam, and a second receiving cavity is provided along the length of the sill beam. That is, the reinforcing beam is a hollow beam and is disposed along the length of the sill beam, thereby improving the overall bending resistance and impact resistance of the sill assembly without significantly increasing its weight. A reinforcing structure is disposed within the second receiving cavity of the reinforcing beam and spans the B-pillar mounting position along the length of the sill beam, meaning that the root area of ​​the B-pillar is reinforced, improving the connection strength at the root of the B-pillar. When the vehicle experiences a side pole impact, the reinforcing structure can absorb some of the impact energy and can transfer and disperse the force to the B-pillar and other body structures, reducing the possibility of tearing at the root of the B-pillar and tearing at the joint between the B-pillar and the upper side beam, thereby reducing the intrusion of the B-pillar during a side pole impact and avoiding the risk of passenger compartment compression. The above solution, by embedding a reinforcing beam and a reinforcing structure within the sill beam, improves the vehicle's side pole impact resistance without significantly increasing the weight of the sill assembly.

[0032] 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.

[0033] Combination Figures 1 to 3 As shown, according to a specific embodiment of this application, a threshold assembly is provided.

[0034] Specifically, the door sill assembly includes: a door sill beam 10, a reinforcing beam 20, and a reinforcing structure 30. The door sill beam 10 has a first receiving cavity 13 and a B-pillar mounting position 14, the first receiving cavity 13 extending along the length of the door sill beam 10. The reinforcing beam 20 is disposed within the first receiving cavity 13 and connected to the door sill beam 10, and the reinforcing beam 20 has a second receiving cavity 22 extending along the length of the door sill beam 10. The reinforcing structure 30 is disposed within the second receiving cavity 22 and connected to the reinforcing beam 20, and the reinforcing structure 30 spans the B-pillar mounting position 14 along the length of the door sill beam 10.

[0035] In this embodiment, the reinforcing beam 20 is disposed within the first receiving cavity 13 of the sill beam 10, and the reinforcing beam 20 extends along the length direction of the sill beam 10 into a second receiving cavity 22. That is, the reinforcing beam 20 is a hollow beam and is disposed along the length direction of the sill beam 10, so as to improve the overall bending resistance and impact resistance of the sill assembly without significantly increasing the weight of the sill assembly. The reinforcing structure 30 is disposed within the second receiving cavity 22 of the reinforcing beam 20 and spans the B-pillar mounting position 14 along the length direction of the sill beam 10. That is, the root area of ​​the B-pillar is reinforced, which improves the connection strength of the B-pillar root. When the vehicle is involved in a side pole collision, the reinforcing structure 30 can absorb part of the impact energy and can transfer and disperse the force to the B-pillar and other body structures, reducing the possibility of tearing at the B-pillar root and tearing at the joint between the B-pillar and the upper side beam, thereby reducing the intrusion of the B-pillar during a side pole collision and avoiding the risk of the passenger compartment being crushed. In the above solution, a reinforcing beam 20 and a reinforcing structure 30 are embedded in the sill beam 10, which improves the side pole impact resistance of the vehicle without significantly increasing the weight of the sill assembly.

[0036] To reduce the weight of the door sill assembly and to achieve a lightweight design for the entire vehicle, aluminum beams are preferred for reinforcement beam 20.

[0037] The reinforcing structure 30 can be integrally formed on the reinforcing beam 20, and the reinforcing structure 30 can also be detachably connected to the reinforcing beam 20.

[0038] Furthermore, the sill beam 10 includes an outer sill plate 11 and an inner sill plate 12, with a first receiving cavity 13 formed between the outer sill plate 11 and the inner sill plate 12, and a reinforcing structure 30 is disposed close to the outer sill plate 11.

[0039] In the embodiments of this application, when the side of the vehicle is impacted by a pillar, the outer side of the vehicle is squeezed inward. The reinforcing structure 30 is located close to the outer door sill plate 11, and the impact force can be transmitted to the door sill beam 10 more quickly through the reinforcing structure 30. Then, it is dispersed along the door sill beam 10 and the reinforcing beam 20 to the entire vehicle body structure. That is, the reinforcing structure 30 can absorb and disperse the collision energy more directly and effectively, thereby reducing the intrusion of the B-pillar, effectively avoiding tearing at the root of the B-pillar and tearing at the joint between the B-pillar and the upper side beam, and protecting the safety of the occupants.

[0040] like Figure 1As shown, the B-pillar outer panel 61 is arranged at the middle part of the rocker outer panel 11, and the B-pillar outer panel 61 is welded to the rocker outer panel 11 along the length direction of the rocker outer panel 11. The B-pillar inner panel 62 and the B-pillar outer panel 61 are arranged opposite to each other along the vehicle body Y-direction, the B-pillar inner panel 62 is arranged at the middle part of the rocker inner panel 12, and the B-pillar inner panel 62 is welded to the rocker inner panel 12 along the length direction of the rocker inner panel 12. The reinforcing structure 30 is arranged along the length direction of the reinforcing beam 20. In the length direction of the reinforcing beam 20, the two welding seams between the B-pillar outer panel 61 and the rocker outer panel 11, and the two welding seams between the B-pillar inner panel 62 and the rocker inner panel 12 are both arranged opposite to the reinforcing structure 30, that is, the reinforcing structure 30 is arranged opposite to the B-pillar, and the reinforcing structure 30 extends to the front and rear sides of the B-pillar along the length direction of the reinforcing beam 20, so as to reinforce the connection part between the B-pillar and the rocker beam 10.

[0041] Specifically, two reinforcing ribs 21 are arranged in the second accommodating cavity 22, the two reinforcing ribs 21 are arranged at intervals along the width direction of the reinforcing beam 20, the two reinforcing ribs 21 divide the second accommodating cavity 22 into a first cavity 221, a second cavity 222 and a third cavity 223, the third cavity 223 is arranged close to the rocker outer panel 11, and the reinforcing structure 30 is arranged in the third cavity 223.

[0042] In the embodiment of the present application, the reinforcing ribs 21 in the reinforcing beam 20 can effectively enhance the bending resistance of the reinforcing beam 20. The third cavity 223 of the reinforcing beam 20 is arranged close to the rocker outer panel 11. When the side of the vehicle is impacted by a pole collision, compared with the first cavity 221 and the second cavity 222, the third cavity 223 is impacted by the collision force earlier. Arranging the reinforcing structure 30 in the third cavity 223 enables the reinforcing structure 30 to directly and quickly absorb and disperse collision energy, thereby reducing the intrusion amount of the B-pillar, effectively avoiding tearing at the root of the B-pillar and tearing at the joint between the B-pillar and the upper side rail, and protecting the safety of occupants.

[0043] As Figure 3 shown, the rocker outer panel 11 and the rocker inner panel 12 are connected by welding, a first accommodating cavity 13 is formed between the rocker outer panel 11 and the rocker inner panel 12, and the reinforcing beam 20 is connected in the first accommodating cavity 13. The reinforcing beam 20 has a second accommodating cavity 22 extending along the length direction of the rocker beam 10, two reinforcing ribs 21 are integrated in the second accommodating cavity 22 of the reinforcing beam 20, and the two reinforcing ribs 21 are arranged at intervals along the width direction of the reinforcing beam 20, so that the cross section of the reinforcing beam 20 presents a "grid" structure, and the arrangement of the reinforcing ribs 21 enhances the overall bending resistance of the reinforcing beam 20. The second accommodating cavity 22 of the reinforcing beam 20 is divided by the reinforcing ribs 21 into a first cavity 221, a second cavity 222 and a third cavity 223, the third cavity 223 is arranged close to the rocker outer panel 11, and the reinforcing structure 30 is connected in the third cavity 223.

[0044] In other embodiments, a reinforcing rib 21 may be arranged in the second accommodating cavity 22 of the reinforcing beam 20, and the cross-section of the reinforcing beam 20 is of a "日"-shaped structure.

[0045] In other embodiments, the number of the reinforcing ribs 21 in the second accommodating cavity 22 of the reinforcing beam 20 may be more than two, for example, three or four.

[0046] In an exemplary embodiment of the present application, the reinforcing structure 30 is a tubular structure, and an outer wall of the reinforcing structure 30 is fitted and disposed against an inner wall of the third chamber 223.

[0047] In the embodiment of the present application, the outer wall of the reinforcing structure 30 is fitted and disposed against the inner wall of the third chamber 223, so as to effectively support a plurality of side walls enclosing the third chamber 223, thereby improving the bending resistance of the reinforcing beam 20 at the B-pillar mounting position 14.

[0048] As Figure 3 shown, the cross-section of the third chamber 223 of the reinforcing beam 20 is trapezoidal, the reinforcing structure 30 is a reinforcing tube with a trapezoidal cross-section, and four side walls of the reinforcing structure 30 are fitted in one-to-one correspondence with four cavity walls of the third chamber 223. For convenient installation, the reinforcing structure 30 is screwed to the reinforcing beam 20 by bolts, or riveted to the reinforcing beam 20.

[0049] In other embodiments, the reinforcing structure 30 may be a reinforcing plate integrally formed in the reinforcing beam 20.

[0050] Preferably, the reinforcing beam 20 is located in the middle of the first accommodating cavity 13, the reinforcing beam 20 divides the first accommodating cavity 13 into a fourth chamber 131 and a fifth chamber 132, and the fourth chamber 131 and the fifth chamber 132 are arranged at intervals along the height direction of the rocker beam 10.

[0051] In the embodiment of the present application, the reinforcing beam 20 is located in the middle of the first accommodating cavity 13, so that the cross-section of the rocker assembly is of a "日"-shaped structure, thereby increasing the sectional moment of inertia of the rocker assembly. When a side pole impact occurs to the vehicle, the deformation of the rocker assembly can be reduced, thereby preventing the passenger compartment from being squeezed.

[0052] Further, the reinforcing beam 20 has a first side wall 24 and a second side wall 25 that are oppositely arranged, the first side wall 24 is arranged close to the rocker outer panel 11, the second side wall 25 is arranged close to the rocker inner panel 12, the first side wall 24 is connected to the rocker outer panel 11, and / or the second side wall 25 is connected to the rocker inner panel 12.

[0053] In the embodiments of this application, the reinforcing beam 20 is connected to the outer sill plate 11 via the first side wall 24 or to the inner sill plate 12 via the second side wall 25, which can enhance the longitudinal bending resistance of the sill beam 10. When the vehicle is involved in a side pillar collision, it can effectively prevent the sill beam 10 from bending and deforming downwards, thereby reducing the possibility of tearing at the root of the B-pillar and tearing at the joint between the B-pillar and the upper beam.

[0054] like Figure 1 As shown, the cavity wall of the first chamber 221 of the reinforcing beam 20 is connected to the inner sill plate 12 by bolts, and the cavity wall of the third chamber 223 of the reinforcing beam 20 is connected to the outer sill plate 11 by bolts.

[0055] In other embodiments, the wall of the first chamber 221 of the reinforcing beam 20 is riveted to the inner sill plate 12, and the wall of the third chamber 223 of the reinforcing beam 20 is riveted to the outer sill plate 11.

[0056] Furthermore, the top wall 26 of the reinforcing beam 20 is connected to the outer sill plate 11 and the inner sill plate 12 via the first connector 40, and the bottom wall 27 of the reinforcing beam 20 is connected to the outer sill plate 11 and the inner sill plate 12 via the second connector 50.

[0057] In the embodiments of this application, the top wall 26 and bottom wall 27 of the reinforcing beam 20 are both connected to the outer sill plate 11 and the inner sill plate 12, enhancing the connection strength between the reinforcing beam 20 and the sill beam 10. This allows the reinforcing beam 20 to provide stable support for the sill beam 10, thereby reducing the twisting and displacement of the sill beam 10 when impacted by a side pillar, and improving the deformation resistance of the sill assembly. Furthermore, the impact force can be transmitted to the top wall 26 and bottom wall 27 of the reinforcing beam 20 through the outer sill plate 11 and the inner sill plate 12, and then dispersed through the internal structure of the reinforcing beam 20, thereby improving the absorption and dispersion efficiency of the impact force.

[0058] like Figure 1 As shown, a plurality of first connectors 40 are riveted to the top wall 26 of the reinforcing beam 20. The plurality of first connectors 40 are spaced apart along the length direction of the reinforcing beam 20. The top wall 26 of the reinforcing beam 20 is welded to the outer sill plate 11 and the inner sill plate 12 through the first connectors 40. A plurality of second connectors 50 are riveted to the bottom wall 27 of the reinforcing beam 20. The plurality of second connectors 50 are spaced apart along the length direction of the reinforcing beam 20. The bottom wall 27 of the reinforcing beam 20 is welded to the outer sill plate 11 and the inner sill plate 12 through the second connectors 50.

[0059] Furthermore, a first flange 111 is provided at the edge of the outer sill plate 11, and a second flange 121 is provided at the edge of the inner sill plate 12. The first flange 111 and the second flange 121 are arranged opposite to each other along the Y direction of the vehicle body. One end of the first connector 40 is connected to the upper surface of the reinforcing beam 20, and the other end of the first connector 40 extends upward to connect with the first flange 111 and the second flange 121. One end of the second connector 50 is connected to the lower surface of the reinforcing beam 20, and the other end of the second connector 50 extends downward to connect with the first flange 111 and the second flange 121.

[0060] In the embodiments of this application, the outer door sill plate 11 and the inner door sill plate 12 are connected to the first connector 40 and the second connector 50 by a flange, which not only simplifies installation but also contributes to the lightweight design of the door sill assembly.

[0061] Furthermore, the first connector 40 is an L-shaped plate or a T-shaped plate, and / or the second connector 50 is an L-shaped plate or a T-shaped plate.

[0062] like Figure 1 , Figure 2 As shown, both the first connector 40 and the second connector 50 are L-shaped plates.
