[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following is for reference. Figures 1-8 A sill beam 1 according to an embodiment of the present invention is described, wherein the sill beam 1 is installed on a vehicle.

[0047] According to a first aspect of the present invention, a sill beam 1 includes: a first sill body 10 and a second sill body 20, the first sill body 10 and the second sill body 20 being arranged and connected along the length direction of the sill beam 1, the first sill body 10 forming a receiving space a for accommodating a vehicle door outward swing mechanism, the second sill body 20 forming a sliding space b, the sliding space b being used for assembling a sliding mechanism of a vehicle sliding door, and the first sill body 10 and the second sill body 20 being made of different materials.

[0048] It should be noted that in the existing technology, the sill beam structure is suitable for vehicles with traditional side-opening doors and B-pillars. However, traditional side-opening doors and B-pillars limit the size of the interior space, and no longer meet consumers' needs for increased interior space.

[0049] Based on this, this application proposes a sill beam 1 structure, comprising a first sill body 10 and a second sill body 20. The first sill body 10 and the second sill body 20 are arranged and connected along the length direction of the sill beam 1, and can be connected by means such as riveting, welding, and bolting. The first sill body 10 and the second sill body 20 divide the sill beam 1 into two parts along the length direction of the sill beam 1. When the sill beam 1 is in the direction of... Figure 7 When placed in the center direction, the length direction of the threshold beam 1 is... Figure 7 In the X direction, when the sill beam 1 is assembled on the vehicle, the length direction of the sill beam 1 corresponds to the front-rear direction of the vehicle. The first sill body 10 is adapted to the front door of the vehicle, and the second sill body 20 is adapted to the rear door of the vehicle. The first sill body 10 forms a receiving space a for accommodating the door swing mechanism of the vehicle. When the front door is closed, the receiving space a is used to accommodate the door swing mechanism to meet the needs of the vehicle to open the door outward. The second sill body 20 forms a sliding space b, and the sliding mechanism of the vehicle sliding door (i.e., the rear door) is assembled in the sliding space b. The rear door is opened or closed by sliding the rear door along the length direction of the sill beam 1.

[0050] The first sill body 10 and the second sill body 20 are made of different materials. Both can be metal components, such as steel-clad aluminum, aluminum-clad steel, or pure sheet metal. This invention uses a front-aluminum, rear-steel structural partition as an example. The first sill body 10 is made of aluminum, and the second sill body 20 is made of steel. Aluminum alloy has a low density and high strength, making it superior to other materials in terms of load-bearing capacity and impact energy absorption. Using aluminum alloy for the first sill body 10 allows for the accommodation of the vehicle door's outward swing mechanism and absorption of side impacts, while also contributing to a lightweight design. The second sill body 20 is made of steel, which has higher strength and hardness. The second sill body 20 is used to assemble the sliding mechanism of the vehicle's sliding door. The steel construction of the second sill body 20 provides better support, increasing its structural strength and, consequently, the structural strength and service life of the sill beam 1.

[0051] Therefore, by installing the sill beam 1 of this application on the vehicle, the first sill body 10 can accommodate the vehicle door outward swing mechanism, and the second sill body 20 can be equipped with the sliding mechanism of the vehicle sliding door. The sill beam 1 can simultaneously meet the requirements of outward swing opening and sliding opening, and can adapt the sill beam 1 to models without B-pillars, which is conducive to increasing the interior space and improving the vehicle's ride comfort.

[0052] In some embodiments of the present invention, such as Figure 7 As shown, the first threshold body 10 may include: a first body 11, the first body 11 defining a first space 111, the outer end of the first space 111 being open along the width direction of the threshold beam 1, and at least a portion of the first space 111 being configured as a receiving space a.

[0053] like Figure 7 As shown, the width direction of the threshold beam 1 is... Figure 7 The Y direction in the diagram. The cross-section of the first main body 11 is as follows: Figure 3 The structure shown can be U-shaped or similar. The first body 11 can be formed by roll forming with a roll forming plate, which has high production efficiency, saves materials, and produces high-strength products. For products like the sill beam 1 that require mass production, roll forming is the most advantageous and economically beneficial process. The first body 11 defines a first space 111 along the width direction of the sill beam 1, such as... Figure 7As shown, the outer end of the first space 111 is open, and the inner end of the first space 111 can be closed. It should be noted that the inner and outer directions involved in this application example are relative concepts, defined by the vehicle body where the sill beam 1 is installed. The direction towards the inside of the vehicle body is called inner, and the direction away from the vehicle body is called outer. At least a portion of the first space 111 is constructed as a receiving space a, that is, at least a portion of the structure of the first space 111 is constructed as a receiving space a, or the entire structure of the first space 111 is constructed as a receiving space a. The receiving space a is used to accommodate the vehicle door outward swing mechanism. By setting the first main body 11, the arrangement of the receiving space a can be realized, so that the first sill main body 10 can meet the usage requirements.

[0054] In some embodiments of the present invention, such as Figure 3 As shown, the first main body 11 may include a first plate 112, a second plate 113, and a third plate 114. The first plate 112 and the third plate 114 are opposite to each other and spaced apart along the height direction of the sill beam 1. The first plate 112 is located at the upper end of the third plate 114. The second plate 113 is connected between the first plate 112 and the third plate 114. Specifically, along the width direction of the sill beam 1, the inner end of the first plate 112 is connected to the second plate 113, and the inner end of the third plate 114 is connected to the second plate 113. The first plate 112, the second plate 113, and the third plate 114 together define a first space 111. The second plate 113 is constructed as the inner end of the first space 111. Along the width direction of the sill beam 1, the length of the first plate 112 is greater than the length of the third plate 114. After the sill beam 1 is installed on the vehicle, it is beneficial to increase the interior space, meet consumer needs, and improve the vehicle's ride comfort.

[0055] like Figure 7 As shown, the front end of the first sill body 10 has a front sealing plate 15, which can cover the front open end of the first space 111. For example, the front sealing plate 15 can cover part of the front open end of the first space 111, or the front sealing plate 15 can cover the entire front open end of the first space 111. The front sealing plate 15 is connected to the first plate 112 and the third plate 114 in the height direction of the sill beam 1, and to the second plate 113 in the width direction of the sill beam 1. The connection can be made by welding, bolting, or other methods, so that at least part of the front open end of the first space 111 is covered. Figure 7 As shown, the height direction of threshold beam 1 is... Figure 7 In the Z direction. By setting the front sealing plate 15, the structural strength of the sill beam 1 is improved.

[0056] In some embodiments of the present invention, such as Figure 3As shown, the first threshold body 10 may further include: an inner support plate 12, which is disposed in the first space 111 and fixedly connected to the first body 11. The inner support plate 12 divides the first space 111 into multiple first subspaces 1111, which are arranged sequentially along the width direction of the threshold beam 1. The first subspace 1111 adjacent to the outer end of the first space 111 is constructed as a receiving space a.

[0057] like Figure 3 As shown, the inner support plate 12 can be a U-shaped structure or a similar U-shaped structure. The inner support plate 12 can be formed by rolling with a roller plate. The inner support plate 12 can include an inner support plate side wall 121, an inner support plate upper wall 122, and an inner support plate bottom wall 123. The inner support plate upper wall 122 and the inner support plate bottom wall 123 are arranged opposite to each other and spaced apart along the height direction of the threshold beam 1. The inner support plate 12 is located in the first space 111. The inner support plate side wall 121 is fixedly connected to the first body 11. For example, the inner support plate upper wall 122 is fixedly connected to the first plate 112 of the first body 11, and the inner support plate bottom wall 123 is fixedly connected to the third plate 114 of the first body 11. The inner support plate 12 and the first body 11 can be connected by welding, bolts, or other methods.

[0058] The inner support plate 12 divides the first space 111 into multiple first sub-spaces 1111. These multiple first sub-spaces 1111 are arranged sequentially along the width direction of the sill beam 1. The first sub-space 1111 adjacent to the outer end of the first space 111 is constructed as a receiving space a. The outer end of the receiving space a is open, thus achieving the effect of arranging the receiving space a. When the front door is closed, the receiving space a is used to accommodate the vehicle's door swing mechanism to meet the vehicle's need to open the door using the swing mechanism. The front sealing plate 15, the inner support plate 12, and the first main body 11 form a closed cavity structure, which can absorb energy when the vehicle is impacted from the side, thereby reducing the impact force and protecting the driver's life. Furthermore, by placing the inner support plate 12 within the first space 111, the inner support plate 12 can support the first main body 11, further enhancing the structural strength of the sill beam 1.

[0059] In some embodiments of the present invention, such as Figure 7As shown, the first threshold body 10 may further include a reinforcing beam 13, at least a portion of which is disposed within the receiving space a, and the reinforcing beam 13 is fixedly connected to the inner support plate 12. The reinforcing beam 13 may be an L-shaped structure and may be a metal component, for example, it may be made of aluminum, but the invention is not limited thereto; the reinforcing beam 13 may also be made of steel. This application uses the example of the reinforcing beam 13 being made of aluminum for illustration. The reinforcing beam 13 and the inner support plate 12 may be fixedly connected by welding, bolting, or other methods. A portion of the structure of the reinforcing beam 13 may be assembled within the receiving space a, or the entire structure of the reinforcing beam 13 may be assembled within the receiving space a. This application uses the example of a portion of the structure of the reinforcing beam 13 being assembled within the receiving space a for illustration. Along the width direction of the threshold beam 1, the outer end of the reinforcing beam 13 extends out of the receiving space a. By placing the reinforcing beam 13 within the receiving space a, the structural strength of the threshold beam 1 can be improved. When a vehicle is involved in a side collision, the reinforced beam 13 first absorbs the impact force and absorbs at least part of the collision energy, ensuring the structural strength of the sill beam 1 and improving the vehicle's safety performance.

[0060] In some embodiments of the present invention, such as Figure 7 As shown, the reinforcing beam 13 may include a side beam 131 and a bottom beam 132. The side beam 131 and the bottom beam 132 are connected to form an angle. The side beam 131 is fixedly connected to the inner wall of the receiving space a, and the bottom beam 132 is connected to the bottom wall of the receiving space a and extends out of the receiving space a.

[0061] In this application example, the side beam 131 can be a plate structure with no internal cavity, while the bottom beam 132 has multiple subspaces (such as...). Figure 3 As shown, the lower end of the side beam 131 is connected to the bottom beam 132 to form an angle. For example, the side beam 131 and the bottom beam 132 are integrally formed, and the side beam 131 is perpendicular or substantially perpendicular to the bottom beam 132. The inner support plate side wall 121 is constructed as the inner side wall of the space a, and the inner support plate bottom wall 123 can be constructed as the bottom wall of the space a, or the third plate 114 can be constructed as the bottom wall of the space a, or the inner support plate bottom wall 123 and the third plate 114 can be jointly constructed as the bottom wall of the space a.

[0062] The side beam 131 and the bottom beam 132 are connected to form an angle, which prevents the sill beam 1 from rotating when subjected to impact forces from the side of the vehicle body, thus ensuring the structural strength of the sill beam 1. The side beam 131 can be fixed to the inner wall (i.e., the inner support plate side wall 121) of the accommodating space a by means of welding, bolting, etc. Similarly, the bottom beam 132 is connected to the bottom wall of the accommodating space a in the same way, such as... Figure 7As shown, the bottom beam 132 extends at least partially out of the receiving space a, so that when the vehicle is subjected to a side impact, the bottom beam 132 first bears the impact force from the side of the vehicle body. After the bottom beam 132 is broken, it continues to impact the side beam 131 and the inner support plate 12, which ensures the structural strength of the sill beam 1 and improves the safety performance of the vehicle.

[0063] In some embodiments of the present invention, the bottom beam 132 has a plurality of collapsible spaces 1321, which are arranged sequentially along the width direction of the sill beam 1. The bottom beam 132 may have two, three, four, or other numbers of collapsible spaces 1321, such as... Figure 3 As shown, as an example, the bottom beam 132 has three crumple zones 1321. Further, along the width direction of the sill beam 1, from the outside to the inside, the cross-sectional widths of the three crumple zones 1321 can be D1, D2, and D3 respectively, satisfying the relationship: D1 < D3 < D2. By providing multiple crumple zones 1321 to the bottom beam 132, energy can be absorbed in stages during a side impact, protecting the driver. When subjected to impact from the side of the vehicle, the crumple zone 1321 with the smallest cross-section on the outer side of the bottom beam 132 absorbs the impact first, reducing the transmission of impact force into the vehicle. The larger and medium-sized crumple zones 1321 then absorb energy, maximizing the reduction of impact force transmission into the vehicle. This allows the sill beam 1 to meet the safety requirements for pole impacts while eliminating the traditional B-pillar, maximizing interior space and satisfying consumers' demand for larger vehicle interiors.

[0064] In some embodiments of the present invention, such as Figure 7 As shown, the side beam 131 has a clearance opening 1311, which can be rectangular or similar to a rectangle. The clearance opening 1311 can penetrate the side beam 131 along the thickness direction of the side beam 131. The clearance opening 1311 is used to avoid components of the door swing mechanism, such as a motor, so that the swing mechanism can be smoothly accommodated in the accommodating space a of the first sill body 10 when the front door is closed, so as to meet the needs of the vehicle to use the swing-out opening door.

[0065] In some embodiments of the present invention, such as Figure 7 As shown, the threshold beam 1 may also include: a latch mounting bracket 14, which is located within the receiving space a and fixed to the reinforcing beam 13, and defines a latch mounting space d.

[0066] The latch mounting bracket 14 is installed within the accommodating space a. The latch mounting bracket 14 can be fixed to the side beam 131 of the reinforcing beam 13, welded to the reinforcing beam 13, bolted to the reinforcing beam 13, or snapped onto the reinforcing beam 13. The latch mounting space d is used to install the latch. When the front door is closed, the latch engages with the door lock on the door to lock the front door securely, preventing it from opening.

[0067] As an example, the latch mounting bracket 14, the side beam 131, and the inner support plate 12 can be provided with coaxial through holes suitable for fasteners (such as screws, bolts, etc.). By having fasteners pass through the through holes on the latch mounting bracket 14, the side beam 131, and the inner support plate 12 simultaneously, the latch mounting bracket 14, the side beam 131, and the inner support plate 12 can be securely assembled, making the assembly simpler and further improving the strength of the latch mounting bracket 14, making the latch more securely installed and reducing the probability of malfunctions when opening and closing the door.

[0068] In some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the second threshold body 20 may include a second body 21 and a first support plate 22. The second body 21 defines a second space 211, which is open at its outer end along the width direction of the threshold beam 1. At least a portion of the first support plate 22 is disposed within the second space 211 to divide the second space 211 into a plurality of second subspaces 2111. The plurality of second subspaces 2111 are arranged along the height direction of the threshold beam 1. The uppermost second subspace 2111 is constructed as a sliding space b. The first support plate 22 is used to support the sliding mechanism.

[0069] In some embodiments, the second body 21 can be integrally formed, resulting in higher structural strength and simpler assembly. In some embodiments, the second body 21 may include two parts: a second upper body plate 212 and a second lower body plate 213. The second upper body plate 212 and the second lower body plate 213 are arranged along the height direction of the sill beam 1, and the second upper body plate 212 and the second lower body plate 213 can overlap along the width direction of the sill beam 1. In this case, along the width direction of the sill beam 1, the orthographic projection of the second upper body plate 212 and the orthographic projection of the second lower body plate 213 have an overlapping area, which is the overlapping area of ​​the second upper body plate 212 and the second lower body plate 213. The second upper body plate 212 and the second lower body plate 213 can be connected by welding, bolts, or other methods.

[0070] The cross-section of the second body 21 can be a U-shaped structure or a similar U-shaped structure, so that the second body 21 defines the second space 211, and the outer end of the second space 211 is open along the width direction of the threshold beam 1, such as... Figure 5As shown, the first support plate 22 may include a horizontal plate and a vertical plate. The vertical plate of the first support plate 22 is fixedly connected to the second main body 21. Further, the vertical plate of the first support plate 22 is fixedly connected to the upper plate 212 of the second main body. At least a portion of the first support plate 22 is disposed in the second space 211 to divide the second space 211 into multiple second subspaces 2111. The multiple second subspaces 2111 are arranged along the height direction of the sill beam 1. The uppermost second subspace 2111 is constructed as a sliding space b. The sliding space b is used to assemble the sliding mechanism of the vehicle sliding door. The sliding mechanism of the vehicle sliding door (i.e., the rear door) is assembled in the sliding space b. The rear door is opened or closed by sliding along the length direction of the sill beam 1. The first support plate 22 serves as the lower plate of the sliding space b to support the sliding mechanism in sliding within the sliding space b to open or close the rear door.

[0071] In some embodiments of the present invention, such as Figure 5 As shown, the second threshold body 20 may further include: a slide rail 23, which is disposed in the sliding space b and fixed to the top wall of the sliding space b. The slide rail 23 is opposite to the first support plate 22 and defines a slide groove 231, which is open at the end facing the first support plate 22.

[0072] The slide rail 23 extends along the length of the sill beam 1 and is located within the sliding space b. A portion of the structure of the second main upper plate 212 forms the top wall of the sliding space b. The slide rail 23 is fixed to the second main upper plate 212; it can be welded to the second main upper plate 212 or fixed to it with bolts. The slide rail 23 is opposite to and spaced apart from the first support plate 22 along the height direction of the sill beam 1, and is located above the first support plate 22. The slide rail 23 can be a U-shaped structure or a similar U-shaped structure, and can be formed by rolling with a roller press. Figure 5 As shown, the opening of the slide groove 231 faces downward towards the first support plate 22. The slide groove 231 can be fitted with a pulley of the sliding mechanism of the vehicle sliding door. When the pulley moves along the length of the slide groove 231, the slide rail 23 limits the pulley, allowing the pulley to move along the length of the slide groove 231, thereby enabling the vehicle sliding door to open or close smoothly along the preset track.

[0073] In some embodiments of the present invention, the first support plate 22 has a boss structure 221 protruding toward the slide rail 23, the boss structure 221 being opposite to the slide rail 23 and used to support the sliding mechanism.

[0074] Among them, such as Figure 5As shown, the first support plate 22 and the boss structure 221 are integrally formed. The boss structure 221 protrudes from the first support plate 22 towards the slide rail 23. The boss structure 221 and the slide rail 23 are positioned opposite each other in the height direction of the sill beam 1. Furthermore, the boss structure 221 is opposite to the open end of the slide groove 231. When the sliding mechanism of the vehicle sliding door is installed in the sliding space b, the pulley of the sliding mechanism can be installed in the slide groove 231. The boss structure 221 can support the sliding mechanism, thereby enabling the sliding mechanism to move smoothly along the slide rail 23. The slide groove 231 allows the vehicle sliding door to open or close more smoothly along the preset track.

[0075] In some embodiments of the present invention, such as Figure 5 and 7 As shown, the second threshold body 20 may further include: a second support plate 24, which is located below the first support plate 22 and is connected between the first support plate 22 and the second body 21 to support the first support plate 22.

[0076] Along the height direction of the threshold beam 1, the second support plate 24 is located below the first support plate 22. The second support plate 24 is fixedly connected to the horizontal plate of the first support plate 22, and the second support plate 24 and the first support plate 22 can be fixedly connected by welding, bolts, or other methods. The second support plate 24 is fixedly connected to the second main body lower plate 213, and the second support plate 24 and the second main body lower plate 213 can overlap along the width direction of the threshold beam 1. At this time, along the width direction of the threshold beam 1, the orthographic projection of the second support plate 24 and the orthographic projection of the second main body lower plate 213 have an overlapping area, which is the overlapping area of ​​the second support plate 24 and the second main body lower plate 213. An angle can be formed between the second support plate 24 and the first support plate 22. The second support plate 24 is connected between the first support plate 22 and the second main body 21. The second support plate 24 can support the first support plate 22, reduce the risk of deformation of the first support plate 22, and thus enable the first support plate 22 to reliably support the vehicle sliding door and prevent the vehicle sliding door from sinking.

[0077] Furthermore, such as Figure 2As shown, the second support plate 24 can also be provided with multiple reinforcing ribs 241. These reinforcing ribs 241 can be distributed along the length of the sill beam 1. For example, the multiple reinforcing ribs 241 are evenly distributed along the length of the sill beam 1, with the same spacing between adjacent reinforcing ribs 241. Each reinforcing rib 241 extends along the height of the sill beam 1. By providing multiple reinforcing ribs 241, the structural strength of the second support plate 24 can be improved, allowing it to more reliably support the first support plate 22. This further reduces the risk of deformation of the first support plate 22, thereby further ensuring the first support plate 22 reliably supports the vehicle sliding door and further preventing the vehicle sliding door from sinking.

[0078] In some embodiments of the present invention, such as Figure 2 As shown, the second support plate 24 can be provided with weight reduction holes 242, which is beneficial to reduce the weight of the second support plate 24 and to achieve the lightweight design of the sill beam 1.

[0079] In some embodiments of the present invention, such as Figure 5 As shown, the second support plate 24 and the first support plate 22 form an included angle β, which satisfies the relationship: 60°≤β≤70°.

[0080] For example, the included angle between the second support plate 24 and the first support plate 22 can be 60°, 62°, 65°, 68°, 70°, etc. The included angle between the second support plate 24 and the first support plate 22 can be within the range of 60° to 70°. Any value, including the endpoint value, is an optional included angle value between the second support plate 24 and the first support plate 22 in this invention. If the included angle between the second support plate 24 and the first support plate 22 is not within the range of 60° to 70°, it will affect the support strength of the second support plate 24 on the first support plate 22 and the service life of the sill beam 1. Therefore, by ensuring that the included angle between the second support plate 24 and the first support plate 22 is greater than or equal to 60° and less than or equal to 70°, the support strength of the second support plate 24 on the first support plate 22 can be improved, further reducing the risk of deformation of the first support plate 22. This further ensures that the first support plate 22 reliably supports the vehicle sliding door, further preventing the vehicle sliding door from sinking, and also improving the structural strength of the sill beam 1, which is beneficial to extending the service life of the sill beam 1.

[0081] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the second body 21 defines a retraction space c. Along the width direction of the threshold beam 1, the retraction space c protrudes towards the inside of the threshold beam 1. The retraction space c and the sliding space b are opposite to and connected. One end of the slide rail 23 extends into the retraction space c.

[0082] The retractable space c is located inside the second main body 21, along the width direction of the threshold beam 1. The retractable space c is located on the side of the sliding space b opposite to its open end. The retractable space c and the sliding space b are adjacent and connected. The retractable space c can be positioned close to the front end of the second main body 21, and the front end of the slide rail 23 can extend into the retractable space c. Figure 7 As shown, the retraction space c protrudes inward toward the sill beam 1. The retraction space c is used to accommodate the sliding mechanism of the vehicle's sliding door when the rear door is closed, which helps to reduce the length of the sill beam 1, thereby reducing its volume. One end of the slide rail 23 extends into the retraction space c, and the slide rail 23 guides the sliding mechanism of the vehicle's sliding door to slide into the retraction space c when the door is closed.

[0084] According to the vehicle of the present application embodiment, the sill beam 1 in the above embodiment can simultaneously satisfy both outward swing opening and sliding opening, and can adapt the sill beam to models without B-pillars, which is beneficial to increasing the interior space.
