[0033] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] According to one embodiment of the present application, a threshold structure is provided. Figures 1 to 7 As shown, the threshold structure includes a threshold body and a support assembly 10. The threshold body has a mounting cavity 16, and the support assembly 10 includes a first support member 12 and a second support member 11, wherein the first support member 12 and the second support member 11 are respectively connected to the inner wall of the mounting cavity 16, and the first support member 12 and the second support member 11 are spaced apart along a first direction.

[0039] In this example, when the threshold structure is subjected to pressure in the first direction, the first support member 12 can be offset against the second support member 11, thereby supporting the threshold body in the first direction. The first support member 12 and the second support member 11 are arranged at intervals along the first direction, so that the support assembly 10 as a whole has a good crushing energy absorption effect, thereby improving the strength of the threshold structure. In addition, the threshold structure of this structure adopts low-cost materials, which can also meet the strength requirements. For example, steel materials are adopted to reduce material costs and process costs.

[0040] The threshold structure is suitable for installation on the vehicle body bracket, and the first direction is the width direction of the vehicle body bracket, that is, Figure 4 The second direction is the length direction of the body support, that is, Figure 4 The first support member 12 faces the outside of the vehicle body, and the second support member 11 faces the inside of the vehicle body. The rocker structure is subjected to pressure in the first direction, that is, the collision of the vehicle body side column 18. The rocker structure is subjected to pressure in the second direction, that is, the small offset collision of the vehicle body.

[0041] like Figures 4 to 6 As shown, the threshold body is suitable for connecting with the rear cross beam 4 and the front cross beam 15 of the seat. When the vehicle body is hit, the threshold structure can reduce the force of the rear cross beam 4 and the front cross beam 15 of the seat, thereby protecting the safety of the passenger compartment. The threshold body is also suitable for connecting with the battery pack mounting beam. When the vehicle body is hit, the threshold structure can reduce the force of the battery pack mounting beam, thereby protecting the safety of the battery pack.

[0042] In an example, Figure 2 and Figure 3 As shown, the first support member 12 and / or the second support member 11 are provided with reinforcing ribs 13 along the first direction. By providing the reinforcing ribs 13 on the first support member 12 and / or the second support member 11, the strength of the support assembly 10 can be improved.

[0043] like Figure 2 and Figure 3 As shown, in this example, both the first support member 12 and the second support member 11 are provided with reinforcing ribs 13. Alternatively, reinforcing ribs 13 may be provided on one of the first support member 12 and the second support member 11. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0044] Taking the second support member 11 as an example, the second support member 11 is provided with a reinforcing rib 13, and the reinforcing rib 13 is provided on the side wall of the second support member 11. The reinforcing rib 13 is provided along the first direction, that is, the length direction of the reinforcing rib 13 is consistent with the first direction. A plurality of reinforcing ribs 13 can be provided, and a plurality of reinforcing ribs 13 are provided at intervals along the circumference of the second support member 11 to further improve the strength of the second support member 11. For example, two, three or four reinforcing ribs can be provided. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0045] The plurality of reinforcing ribs 13 may be respectively disposed on two opposite sides of the second support member 11 along the second direction. Also, the second support member 11 may be provided with the same reinforcing ribs 13 as the first support member 12 .

[0046] In one example, Figure 2 As shown, the reinforcing rib 13 is provided with a first through hole 131 along the second direction. The reinforcing rib 13 is provided with the first through hole 131. When the support assembly 10 is subjected to pressure, the first through hole 131 can guide the crushing, and can crush and absorb energy while ensuring sufficient supporting force along the first direction, so as to reduce the force of the seat crossbeam and the pressure on the battery pack.

[0047] In this example, the first support member 12 is provided with a reinforcing rib 13, and the reinforcing rib 13 is provided with a first through hole 131 along the second direction, so that the reinforcing rib 13 can be divided into two along the first direction. When the support assembly 10 is subjected to pressure, the two reinforcing ribs 13 can collide with each other, and the first through hole 131 can play a role in guiding the crushing.

[0048] In this example, the first support member 12 is provided with a plurality of reinforcing ribs 13, and each reinforcing rib 13 may be provided with a first through hole 131. The reinforcing ribs 13 on the second support member 11 may have the same structure as the reinforcing ribs 13 on the first support member 12.

[0049] like Figure 3 As shown, in this example, the first support member 12 is further provided with a second through hole 121, which can reduce the weight of the second support member 11 and is conducive to the lightweight design of the door sill structure. The second support member 11 can also be provided with a second through hole 121 for weight reduction. The position and specific size of the second through hole 121 can be determined by those skilled in the art according to actual conditions, as long as the strength of the first support member 12 and the second support member 11 can be ensured, and no specific limitation is made here.

[0050] In one example, Figure 2 As shown, the distance between the first support member 12 and the second support member 11 is greater than or equal to 10 mm.

[0051] like Figure 2 As shown, the first support member 12 and the second support member 11 are spaced apart along the first direction, so that the first support member 12 and the second support member 11 cooperate with each other to achieve good energy absorption effect. And the spacing distance D1 is greater than or equal to 10 mm, which can avoid the first support member 12 and the second support member 11 from making abnormal noise due to collision during the driving of the vehicle.

[0052] For example, the distance D1 between the first support member 12 and the second support member 11 may be 10 mm, 11 mm, or 12 mm, etc. Those skilled in the art may determine the distance based on actual conditions, and no specific limitation is made herein.

[0053] In one example, Figure 2 As shown, along the second direction, the lengths of the first support member 12 and the second support member 11 are 90 mm to 110 mm, which can ensure that the support assembly 10 can play a better supporting role when the side column 18 collides.

[0054] For example, the length D2 of the first support member 12 and the second support member 11 along the second direction may be 90 mm, 95 mm, 100 mm or 110 mm, etc. Those skilled in the art may determine it according to actual conditions, and no specific limitation is made here.

[0055] In an example, Figure 5 As shown, there are multiple support assemblies 10, and the multiple support assemblies 10 are arranged at intervals along the second direction, and the interval between two adjacent support assemblies 10 is 90mm to 110mm. By arranging multiple support assemblies 10 along the second direction, the strength of the door sill structure can be further improved.

[0056] In this example, in the collision of the side column 18, the radius of the side column 18 is approximately 127 mm, and the interval between two adjacent support assemblies 10 is 90 mm to 110 mm, so that when the collision column hits the threshold, it can collide with the two support assemblies 10, and the two support assemblies 10 can more effectively reduce the pressure in the first direction.

[0057] Among them, five, six or seven support assemblies 10 can be provided. The interval between two adjacent support assemblies 10 can be 90 mm, 95 mm, 100 mm or 110 mm, etc. Of course, the number and interval distance of the support assemblies 10 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0058] like Figure 5 As shown, in this example, the passenger sits on the seat, and the support assembly 10 corresponding to the center of mass of the passenger's head is set as the first group, that is, the support assembly 10 closest to the center of mass of the passenger's head is set as the first group, such as Figure 5 The support assembly numbered 10-1 is set as the first group of support assemblies 10-1. The angle θ between the center of mass of the passenger's head and the line connecting the first group of support assemblies 10 and the longitudinal center line of the vehicle is 75°±3°. A plurality of support assemblies 10 are sequentially arranged at intervals on both sides of the first group of support assemblies 10-1 along the second direction.

[0059] In one example, a portion of the support assembly 10 is connected to the inner wall of the mounting cavity 16, and a gap is formed between the other portion and the inner wall, and the gap between the support assembly 10 and the inner wall is greater than or equal to 3 mm. A portion of the support assembly 10 is connected to the inner wall of the mounting cavity 16, and a gap is formed between the other portion and the inner wall, thereby avoiding large-area contact between the support assembly 10 and the inner wall of the mounting cavity 16, which may cause collision noise when the vehicle moves.

[0060] In this example, taking the first support member 12 as an example, the first support member 12 is welded to the threshold body. A welding point is provided on the first support member 12, and the welding point is welded to the threshold body. There is a gap between the other parts of the first support member 12 except the welding point and the inner wall of the installation cavity 16 to avoid large-area contact between the support assembly 10 and the inner wall of the installation cavity 16, which may cause collision noise when the vehicle moves.

[0061] The gap between the first support member 12 and the inner wall of the installation cavity 16 is greater than or equal to 3 mm. For example, it can be 3 mm, 4 mm or 4.5 mm, etc. Those skilled in the art can determine it according to the actual situation, and it is not specifically limited here.

[0062] In this example, the first support member 12 may also be connected to the door sill body in other ways, for example, by screw connection, etc. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.

[0063] In this example, the second support member 11 can be connected in the same manner as the first support member 12 , which will not be described in detail herein.

[0064] In an example, Figure 2 and Figure 3 As shown, the first support member 12 and the second support member 11 respectively include a bottom plate 122 , and the bottom plate of the first support member 12 and the bottom plate of the second support member 11 are spaced apart along the first direction.

[0065] like Figure 2 and Figure 3As shown, the first support member 12 and the second support member 11 have the same structure, both of which are U-shaped structures, and the first support member 12 and the second support member 11 are arranged back to back. The bottom plates of the first support member 12 and the second support member 11 are arranged at intervals along the first direction, and the interval is D1. When the threshold structure is subjected to a force in the first direction, the two bottom plates 122 can offset each other to resist the external force.

[0066] In an example, Figure 2 and Figure 3 As shown, the first support member 12 further includes two side plates 123 , which are respectively located on both sides of the bottom plate 122 , one end of the side plate 123 is connected to the bottom plate 122 , and the other end is connected to the inner wall.

[0067] In this example, the first support member includes two side plates 123, which are arranged on opposite sides of the bottom plate 122 along the second direction to form a U-shaped structure with the bottom plate. One end of the side plate 123 is connected to the bottom plate 122, and the other end is connected to the inner wall. Alternatively, the first support member 12 may also be other structures, which can be determined by those skilled in the art according to actual conditions and are not limited here.

[0068] The second support member 11 may have the same structure as the first support member 12 , which will not be described in detail herein.

[0069] In an example, Figure 1 , Figures 4 to 7 As shown, the threshold body includes a first plate body 1 and a second plate body 2 , the first plate body 1 is connected to the second plate body 2 to form the installation cavity 16 , the first support member 12 is connected to the first plate body 1 , and the second support member 11 is connected to the second plate body 2 .

[0070] In this example, the threshold plate body includes a first plate body 1 and a second plate body 2 arranged along a first direction, and one end of the first plate body 1 is connected to the second plate body 2 to form a mounting cavity 16. When the threshold structure is assembled, the first support member 12 is first connected to the first plate body 1, the second support member 11 is connected to the second plate body 2, and then the first plate body 1 is connected to the second plate body 2, so as to facilitate the connection between the first support member 12 and the second support member 11. The first plate body 1 and the second plate body 2 can be connected by welding or screwing.

[0071] like Figure 1 As shown, in this example, the first plate body 1 and the second plate body 2 are both slot structures, and the opening end of the first plate body 1 is connected to the opening end of the second plate body 2, so that the installation cavity 16 can be formed.

[0072] The first plate body 1 and the second plate body 2 may be steel plates.

[0073] In an example, Figure 1 , Figure 6 and Figure 7 As shown, the threshold structure further includes a first reinforcement member 6, which is disposed in the installation cavity 16 and arranged along the second direction. The first reinforcement member 6 is arranged in the installation cavity 16 along the second direction, and the first reinforcement member 6 can provide support force in the second direction.

[0074] In this example, when the vehicle is hit by a 25% small offset collision, the tire 17 will hit the threshold structure, generating a force in the second direction on the threshold structure. The first reinforcement member 6 is connected to the inner wall of the mounting cavity 16 along the second direction, and can provide a supporting force in the second direction for the threshold body, thereby improving the strength of the threshold structure.

[0075] In this example, one end of the sill body extends to the A-pillar reinforcement plate 14 and is welded to the A-pillar reinforcement plate 14. The A-pillar reinforcement plate 14 is used to connect to the A-pillar. One end of the first reinforcement member 6 extends along the second direction to the position of the A-pillar reinforcement plate 14, and the other end of the first reinforcement member 6 extends to the position of the rear cross beam 4 of the seat. The length of the first reinforcement member 6 can meet the strength requirements. Avoid the first reinforcement member 6 being too long to increase the weight of the sill structure.

[0076] The first reinforcement member 6 may be made of steel, and the material cost and process cost are relatively low.

[0077] In one example, a portion of the first reinforcement 6 is connected to the inner wall of the installation cavity 16, and a gap is formed between the other portion and the inner wall of the installation cavity 16. A portion of the first reinforcement 6 is connected to the inner wall of the installation cavity 16, and a gap is formed between the other portion and the inner wall of the installation cavity 16, so as to avoid large-area contact between the first reinforcement 6 and the inner wall of the installation cavity 16, which may cause collision noise when the vehicle moves.

[0078] In this example, the first reinforcement 6 can be welded to the inner wall of the installation cavity 16. The first reinforcement 6 is provided with welding points, which are welded to the inner wall of the installation cavity 16. The gap between the other parts of the first reinforcement 6 except the welding points and the inner wall of the installation cavity 16 is 3 mm, so as to avoid large-area contact between the first reinforcement 6 and the inner wall of the installation cavity 16, which may cause collision noise when the vehicle moves.

[0079] For example, the gap between the first reinforcement member 6 and the inner wall of the installation cavity 16 may be 3 mm, 4 mm, or 4.5 mm, etc. Those skilled in the art may determine the gap based on actual conditions, and no specific limitation is made here.

[0080] Part of the welding points of the support assembly 10 may also be welded to the first reinforcement member 6 .

[0081] In an example, Figure 1As shown, a plurality of first reinforcement members 6 are provided, and the plurality of first reinforcement members 6 are arranged at intervals along the circumferential direction of the installation cavity 16. By providing a plurality of first reinforcement members 6, the strength of the rocker structure can be further improved.

[0082] In this example, if Figure 7 As shown, two first reinforcement members 6 are arranged at intervals on the first plate body 1, and two first reinforcement members 6 are arranged at intervals on the second plate body 2. For example, the first reinforcement member 6 can be an angle steel, and the angle steel can be connected to the bending part of the first plate body 1. The angle steel can be an L-shaped angle steel or other shapes, and can be arranged according to the structure of the first plate body 1 and the second plate body 2.

[0083] In an example, Figure 1 and Figure 6 As shown, the second plate body 2 is suitable for connecting with a structural member, and the threshold structure further includes a second reinforcement member 8 arranged along a second direction, the second reinforcement member 8 is connected to the second plate body 2, and the first reinforcement member 6 is connected to the second reinforcement member 8. By providing the second reinforcement member 8, the strength of the threshold body can be further improved.

[0084] In this example, the second plate body 2 is suitable for connection with structural members, that is, the second plate body 2 faces the inner side of the vehicle body. Structural members include components such as a seat rear cross beam 4, a seat front cross beam 15 or a battery pack cross beam. The seat rear cross beam 4 and the seat front cross beam 15 are welded to the second plate body 2. The inner wall of the second plate body 2 is also connected to a second reinforcement 8, and the second reinforcement 8 is arranged along the second direction. The second reinforcement 8 has the same function as the first reinforcement 6. The first reinforcement 6 can be connected to the second reinforcement 8, thereby connecting to the inner wall of the mounting cavity 16, and the first reinforcement 6 and the second reinforcement 8 cooperate to improve the strength of the threshold structure.

[0085] In this example, the second reinforcement 8 can be welded to the first reinforcement 6, and the first reinforcement 6 is provided with welding points, through which it is welded to the second reinforcement 8. Except for the connection position with the second reinforcement 8, the other parts of the first reinforcement 6 have a gap with the second reinforcement 8. This is to avoid large-area contact between the first reinforcement 6 and the second reinforcement 8, which may cause collision noise when the vehicle moves. For example, the gap between the first reinforcement 6 and the second reinforcement 8 can be 3mm, 4mm or 4.5mm, etc., which can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0086] In this example, the second reinforcement member 8 may be a steel plate, and the second reinforcement member 8 is attached to the inner wall of the second plate body 2. The second reinforcement member 8 may be M-shaped or in other shapes, and may be arranged according to the structure of the second plate body 2.

[0087] Of course, a second reinforcement member 8 may also be provided on the first plate body 1 .

[0088] According to another embodiment of the present application, a vehicle is provided, which includes the door sill body of the above embodiment.

[0089] In this example, the threshold structure includes a threshold body and a support assembly 10. The threshold body has an installation cavity 16, and the support assembly 10 includes a first support member 12 and a second support member 11, the first support member 12 and the second support member 11 are respectively connected to the inner wall of the installation cavity 16, and the first support member 12 and the second support member 11 are spaced apart along the first direction. When the threshold structure is subjected to pressure along the first direction, the first support member 12 can be offset against the second support member 11, and play a supporting role for the threshold body in the first direction. The first support member 12 and the second support member 11 are spaced apart along the first direction, which also enables the support assembly 10 as a whole to have a better crushing energy absorption effect, so as to improve the strength of the threshold structure. And the threshold structure of this structure adopts low-cost materials, which can also meet the strength requirements. For example, steel materials are adopted to reduce material costs and process costs.

[0090] Of course, the vehicle of the present application also includes at least all the beneficial effects of the above-mentioned embodiments, which will not be repeated here.

[0091] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
