[0028] Please refer to Figure 1 , Figure 1 is a schematic structural diagram of an embodiment of a sill assembly of a vehicle provided by the present application. The present application provides a sill assembly 100 of a vehicle. The sill assembly 100 includes an inner panel 10, a door ring 20, an outer panel 30, and a sill beam assembly 40. The door ring 20 is connected to the inner panel 10 along the first direction X-X, and a receiving cavity 100a is formed between the door ring 20 and the inner panel 10; the outer panel 30 is disposed on the side of the door ring 20 facing away from the inner panel 10; the sill beam assembly 40 is disposed in the receiving cavity 100a. The sill beam assembly 40 includes a reinforcing beam 41 and a support member 42. The reinforcing beam 41 extends along the first direction X-X and is connected between the inner panel 10 and the door ring 20. The support member 42 is disposed between one side of the reinforcing beam 41 and the door ring 20 for supporting the reinforcing beam 41.

[0029] Among them, the inner panel 10 is located on the side of the sill assembly 100 facing the interior of the vehicle, and the outer panel 30 is located on the side of the sill assembly 100 facing away from the interior of the vehicle. For example, the inner panel 10 can be disposed on the side of the sill assembly 100 facing the driver's cab of the vehicle, and the outer panel 30 can be disposed on the side of the sill assembly 100 facing away from the driver's cab of the vehicle. The door ring 20 is located on the side of the outer panel 30 facing the inner panel 10. The inner panel 10, the door ring 20, and the outer panel 30 are arranged in sequence along the first direction X-X. The two sides of the door ring 20 are bent in the direction facing the inner panel 10 along the second direction Y-Y and extend in the direction facing the inner panel 10; the two sides of the inner panel 10 are bent in the direction facing the door ring 20 along the second direction Y-Y and extend in the direction facing the door ring 20, and are connected to the two sides of the door ring 20 along the second direction Y-Y to form a receiving cavity 100a for receiving the sill beam assembly 40 between the door ring 20 and the inner panel 10. The second direction Y-Y is perpendicular to the first direction X-X.

[0030] Wherein, when the vehicle has a side collision, the first direction X-X is parallel to the force direction of the sill assembly 100. By making the extending direction of the reinforcing beam 41 parallel to the force direction of the sill assembly 100, when the reinforcing beam 41 is subjected to an external force, it can better resist deformation, which helps to improve the structural strength and rigidity of the sill assembly 100; at the same time, the reinforcing beam 41 can effectively disperse and absorb collision energy, which helps to improve the collision energy absorption ability of the sill assembly 100.

[0031] In the embodiment of the present application, the reinforcing beam 41 is connected between the inner plate 10 and the door ring 20 along the first direction X-X, and the support member 42 is arranged between one side of the reinforcing beam 41 and the door ring 20. On the one hand, the arrangement of the support member 42 can provide sufficient fixation and support for the reinforcing beam 41, enhance the structural strength of the reinforcing beam 41, and enable the reinforcing beam 41 to fully exert its excellent energy absorption effect. Therefore, when the vehicle has a side collision, the reinforcing beam 41 can effectively absorb and disperse collision energy, so that the energy absorption effect and collision safety performance of the sill assembly 100 can be significantly improved. On the other hand, the structure of the sill assembly 100 is simple, which is beneficial to reducing the weight of the sill assembly 100 and achieving a lightweight effect.

[0032] In some embodiments, the accommodation cavity 100a is filled with aluminum foam material. The aluminum foam material is a porous material with excellent energy absorption characteristics. The aluminum foam material can be connected to the inner plate 10, the door ring 20 and the sill beam assembly 40, so that the sill assembly 100 forms a composite structure, which can improve the structural strength and stiffness of the sill assembly 100; at the same time, by filling the aluminum foam material in the accommodation cavity 100a, when the vehicle has a side collision, the aluminum foam material can also absorb side collision energy through deformation, so that the energy absorption effect and collision safety performance of the sill assembly 100 are further improved.

[0033] In some embodiments, please refer to Figure 2 , Figure 2 is a schematic cross-sectional structure diagram of an embodiment of the sill assembly of the vehicle provided by the present application. One side of the door ring 20 for connecting the reinforcing beam 41 is bent, so as to form an adjacent recess 21 and a protrusion 22 on the side of the door ring 20 facing away from the accommodation cavity 100a, and the outer plate 30 is at least partially accommodated in the recess 21.

[0034] Wherein, the recessed portion 21 is formed by the door ring 20 protruding toward the accommodating cavity 100a, and is recessed on the side of the door ring 20 facing away from the accommodating cavity 100a. The recessed portion 21 and the protruding portion 22 are arranged adjacent to each other along the second direction Y-Y. Both the side of the recessed portion 21 facing the accommodating cavity 100a and the side of the recessed portion 21 facing away from the accommodating cavity 100a are flat surfaces, and both of these flat surfaces are perpendicular to the first direction X-X. Both the side of the protruding portion 22 facing the accommodating cavity 100a and the side of the protruding portion 22 facing away from the accommodating cavity 100a are flat surfaces, and both of these flat surfaces are perpendicular to the first direction X-X. The connecting surface between the protruding portion 22 and the recessed portion 21 is an arc surface, which can not only reduce stress concentration, but also reduce the safety hazards brought by sharp corners, effectively improving the safety and aesthetics of the door sill assembly 100.

[0035] The reinforcing beam 41 is connected between the side of the recessed portion 21 facing the accommodating cavity 100a and the side of the inner plate 10 facing the accommodating cavity 100a. The side of the inner plate 10 for connecting the reinforcing beam 41 is a flat surface, and this flat surface is perpendicular to the first direction X-X. By setting the side of the recessed portion 21 facing the accommodating cavity 100a as a flat surface and the side of the inner plate 10 for connecting the reinforcing beam 41 as a flat surface, the connection strength and stability of the reinforcing beam 41 can be improved, thereby enhancing the structural strength of the reinforcing beam 41, and further enhancing the overall rigidity of the door sill assembly 100, which can provide strong support for the vehicle body.

[0036] In some embodiments, the outer plate 30 is at least partially received in the recessed portion 21 and is fixed to the side of the recessed portion 21 facing away from the accommodating cavity 100a.

[0037] By at least partially receiving the outer plate 30 in the recessed portion 21, on the one hand, the structure of the door sill assembly 100 becomes more compact, which can enhance the structural strength of the door sill assembly 100 and improve the collision safety performance of the door sill assembly 100; on the other hand, the side of the outer plate 30 facing away from the door ring 20 will not protrude too much, which can improve the aesthetics of the door sill assembly 100.

[0038] In some embodiments, please refer to Figure 3 , Figure 3 is a schematic structural diagram of another embodiment of the door sill assembly of the vehicle provided by the present application. The outer plate 30 includes a first extension portion 31, an outer plate main body 32, and a second extension portion 33 that are connected in sequence. The first extension portion 31 is arranged along the second direction Y-Y on the side of the door ring 20 facing away from the inner plate 10, and the second extension portion 33 is arranged in the recessed portion 21. Wherein, the side of the outer plate main body 32 facing away from the accommodating cavity 100a is flush with the side of the protruding portion 22 facing away from the accommodating cavity 100a.

[0039] Among them, the first extension part 31 and the second extension part 33 are connected to both sides of the outer plate main body 32 along the second direction Y-Y, and are inclined relative to the first direction X-X. The joints between the first extension part 31 and the outer plate main body 32 and between the second extension part 33 and the outer plate main body 32 are in an arc chamfer structure, which can eliminate acute angles, disperse stress, and thus improve the stability and rigidity of the structure of the outer plate 30.

[0040] Among them, at least part of the first extension part 31 and the door ring 20 are arranged along the second direction Y-Y, and the side of the first extension part 31 facing away from the outer plate main body 32 is arranged on the side of the door ring 20 facing away from the inner plate 10. The outer plate main body 32 is spaced apart from the side of the recess 21 facing away from the accommodation cavity 100a. The side of the second extension part 33 facing away from the outer plate main body 32 extends towards the recess 21 and is arranged in the recess 21. For example, the side of the second extension part 33 facing away from the outer plate main body 32 can be arranged on the side of the recess 21 facing away from the accommodation cavity 100a. A cavity 20a is formed between the door ring 20 and the outer plate 30. The cavity 20a can be used to absorb collision energy when the vehicle undergoes a side collision, which is beneficial to improving the energy absorption effect and collision safety performance of the sill assembly 100.

[0041] In some embodiments, the cavity 20a can be filled with aluminum foam material to further improve the energy absorption effect and collision safety performance of the sill assembly 100.

[0042] By making the side of the outer plate main body 32 facing away from the accommodation cavity 100a flush with the side of the protrusion 22 facing away from the accommodation cavity 100a, the structure of the sill assembly 100 is made compact, reducing the sense of abruptness. When the sill assembly 100 is applied to a vehicle, it can make the body appearance of the vehicle more harmonious and unified, thereby improving the overall aesthetic feeling of the vehicle.

[0043] In some embodiments, the support member 42 includes a first fixing portion 421, a support main body 422, and a second fixing portion 423 that are connected in sequence. The first fixing portion 421, the support main body 422, and the second fixing portion 423 can be an integrally formed structure. The integrally formed structure not only ensures the structural strength of the support member 42, but also simplifies the number of parts of the support member 42, improving the assembly efficiency. Of course, the first fixing portion 421, the support main body 422, and the second fixing portion 423 can also be fixedly connected. The fixed connection method can be riveting, welding, bonding, bolt connection, key connection, snap connection, or magnetic adsorption connection, but is not limited thereto.

[0044] The support main body 422 and the reinforcing beam 41 are spaced apart along the second direction Y-Y, which can reduce the risk of the support main body 422 rubbing against the reinforcing beam 41, thereby improving the reliability of the reinforcing beam 41.

[0045] The first fixing portion 421 extends along the second direction Y-Y such that the extending direction of the first fixing portion 421 is parallel to the plane where the side of the recessed portion 21 of the door ring 20 facing the accommodation cavity 100a is located. The second fixing portion 423 extends along the first direction X-X such that the extending direction of the second fixing portion 423 is parallel to the side of the reinforcing beam 41 opposite to the support member 42. The first fixing portion 421 is fixed to the door ring 20, and the second fixing portion 423 is fixed to the reinforcing beam 41. Specifically, the first fixing portion 421 is fixed to the side of the recessed portion 21 of the door ring 20 facing the accommodation cavity 100a, and the second fixing portion 423 is fixed to the side of the reinforcing beam 41 opposite to the support member 42, which can improve the connection strength between the support member 42 and the door ring 20 and the connection strength between the support member 42 and the reinforcing beam 41, thereby enhancing the fixing and supporting effect of the support member 42 on the reinforcing beam 41, and further strengthening the structural strength of the reinforcing beam 41. When a side collision occurs to the vehicle, the reinforcing beam 41 can effectively absorb and disperse the collision energy.

[0046] In some embodiments, the first fixing portion 421 is provided with a first mounting hole, the door ring 20 is provided with a second mounting hole, and the outer panel 30 is provided with a third mounting hole. The first mounting hole, the second mounting hole and the third mounting hole are adapted to each other and can be coaxially arranged. The number of the first mounting hole, the second mounting hole and the third mounting hole can be 1, 2, 3, 5, 6, etc., but is not limited thereto. The specific number of the first mounting hole, the second mounting hole and the third mounting hole can be selected according to the size of the first fixing portion 421.

[0047] The first mounting hole, the second mounting hole and the third mounting hole are used to cooperate with the mounting member 43 to mount the support member 42 on the door ring 20 and the outer panel 30. The mounting manner of the first fixing portion 421 on the door ring 20 and the outer panel 30 is reliable and the number of types of components is small, which can not only improve the mounting efficiency of the support member 42, but also reduce the weight of the sill assembly 100 to achieve a lightweight effect.

[0048] In some embodiments, a receiving groove 20b is formed between the protruding portion 22 of the door ring 20 and the outer panel 30. The connecting surface between the protruding portion 22 and the recessed portion 21 is one side wall of the receiving groove 20b, a part of the second extending portion 33 of the outer panel 30 is the other side wall of the receiving groove 20b, another part of the second extending portion 33 of the outer panel 30 is at least part of the bottom wall of the receiving groove 20b, and the third mounting hole of the outer panel 30 is provided in the other part of the second extending portion 33. One end of the mounting member 43 located outside the accommodation cavity 100a is received in the receiving groove 20b. The end of one end of the mounting member 43 located outside the accommodation cavity 100a is completely received in the receiving groove 20b, or the end of one end of the mounting member 43 located outside the accommodation cavity 100a is flush with the side of the protruding portion 22 facing away from the accommodation cavity 100a, thereby improving the appearance effect of the sill assembly 100.

[0049] In some embodiments, the second fixing portion 423 is provided with a fourth mounting hole, and the reinforcing beam 41 is provided with a fifth mounting hole. The fourth mounting hole is adapted to the fifth mounting hole and can be coaxially arranged. The numbers of the fourth mounting hole and the fifth mounting hole can be 1, 2, 3, 5, 6, etc., but are not limited thereto. The specific numbers of the fourth mounting hole and the fifth mounting hole can be selected according to the size of the second fixing portion 423.

[0050] The fourth mounting hole and the fifth mounting hole are used to cooperate with the mounting member 43 to mount the support member 42 on the reinforcing beam 41. The mounting method of the second fixing portion 423 on the reinforcing beam 41 is reliable and the number of types of components is small. It can not only improve the mounting efficiency of the support member 42, but also reduce the weight of the sill assembly 100 to achieve a lightweight effect.

[0051] Among them, the mounting member 43 can be a bolt, a screw, a stud or a rivet, but is not limited thereto.

[0052] In some embodiments, the reinforcing beam 41 extends along a third direction Z-Z perpendicular to the first direction X-X and the second direction Y-Y. The sill beam assembly 40 includes a plurality of support members 42, and the plurality of support members 42 are spaced along the third direction Z-Z. The number of the support members 42 can be 2, 3, 5, 6, 7, 10, etc., but is not limited thereto. The specific number of the support members 42 can be selected according to the size of the reinforcing beam 41 along the third direction Z-Z.

[0053] In some embodiments, please continue to refer to Figures 2 to 3 , the reinforcing beam 41 is formed with a plurality of energy absorption cavities 411, and the plurality of energy absorption cavities 411 are arranged along the first direction X-X. By arranging the plurality of energy absorption cavities 411 of the reinforcing beam 41 along the first direction X-X, that is, the plurality of energy absorption cavities 411 are arranged along the force direction of the sill assembly 100, the energy absorption effect of the reinforcing beam 41 can be effectively improved, so that when the vehicle has a side collision, the reinforcing beam 41 can better absorb and disperse the collision energy, which is beneficial to improving the reliability and stability of the vehicle.

[0054] In some embodiments, the fifth mounting hole for mounting the support member 42 on the reinforcing beam 41 is provided in a region of the reinforcing beam 41 corresponding to the energy absorption cavity 411.

[0055] In some embodiments, the reinforcing beam 41 is an integrally formed part. By designing the reinforcing beam 41 as an integrally formed part, not only can the overall rigidity and impact resistance of the reinforcing beam 41 be improved, but also the structure of the reinforcing beam 41 can be simplified, the complexity of the structure of the reinforcing beam 41 can be reduced, and the overall weight of the reinforcing beam 41 can be effectively reduced, which is beneficial to achieving a lightweight effect.

[0056] In some embodiments, please continue to refer toFigures 2 to 3 Between two adjacent energy-absorbing cavities 411, a reinforcing rib 412 is provided. The plane where the reinforcing rib 412 is located is perpendicular to the first direction X-X. That is, the plane where the reinforcing rib 412 is located is perpendicular to the force direction of the sill assembly 100.

[0057] In some embodiments, the reinforcing beam 41 is a thermoplastic material reinforcing beam 41.

[0058] In some embodiments, the thermoplastic material can be a thermoplastic composite material. For example, a thermoplastic resin composite material, a glass fiber reinforced thermoplastic composite material, a continuous fiber reinforced thermoplastic composite material, a carbon fiber reinforced thermoplastic composite material, etc., but not limited thereto.

[0059] The material of the reinforcing beam 41 is selected from thermoplastic materials. On the one hand, thermoplastic materials have a low density and excellent mechanical properties. While maintaining the structural strength and rigidity of the reinforcing beam 41, they can also reduce the weight of the reinforcing beam 41, which is beneficial for the sill assembly 100 to achieve a lightweight effect. On the other hand, thermoplastic materials have a relatively better energy absorption effect, enabling the reinforcing beam 41 to effectively absorb and disperse collision energy. Thirdly, thermoplastic materials have the ability to be reshaped, enabling the reinforcing beam 41 to be recycled, which helps to reduce pollution and promotes the sustainable development of the vehicle field.

[0060] In some embodiments, the sill beam assembly 40 further includes a connecting member 44. The connecting member 44 is disposed between the reinforcing beam 41 and the door ring 20 and / or between the reinforcing beam 41 and the inner panel 10.

[0061] By disposing the connecting member 44 between the reinforcing beam 41 and the door ring 20 and / or between the reinforcing beam 41 and the inner panel 10, the reinforcing beam 41 can be better fixed, thereby enhancing the structural strength of the reinforcing beam 41.

[0062] In some embodiments, the connecting member 44 is a structural adhesive.

[0063] By disposing the structural adhesive between the reinforcing beam 41 and the door ring 20 and / or between the reinforcing beam 41 and the inner panel 10, on the one hand, the structural adhesive has strong viscosity and elasticity, which can not only enhance the structural strength of the reinforcing beam 41, but also improve the anti-vibration performance of the sill assembly 100. On the other hand, the structural adhesive can evenly disperse stress, which can improve the overall structural strength and rigidity of the sill assembly 100. Thirdly, the structural adhesive is light in weight, which can enhance the lightweight effect of the sill assembly 100.

[0064] In some embodiments, the structural adhesive is an epoxy resin structural adhesive, a polyurethane structural adhesive or an acrylic structural adhesive.

[0065] This application also provides a vehicle, which includes the sill assembly 100 in any of the above embodiments.

[0066] In the technical solution of the embodiment of the present application, the specific structure of the sill assembly 100 refers to the above embodiment.
