Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicles, and in particular to a rocker reinforcement beam assembly, a rocker beam, and a vehicle. Background Art

[0002] A vehicle's rocker beam is a critical structure for ensuring safety in small-offset frontal collisions. It supports the barrier against which the vehicle collides, preventing it from squeezing the A-pillar and causing it to intrude excessively into the cockpit.

[0003] Therefore, how to improve the strength of the sill beam is an important prerequisite for improving vehicle safety. Summary of the Invention

[0004] The present disclosure provides a sill reinforcement beam assembly, a sill beam, and a vehicle. The sill reinforcement beam assembly includes a sill reinforcement beam and a support member. The support member's support boss extends into the cavity of the sill reinforcement beam and abuts against the vertical plates on either side. When the sill reinforcement beam assembly is mounted on the inner sill panel, a connecting member passes through the support boss and at least two vertical plates and connects to the inner sill panel, thereby enhancing the connection strength between the sill reinforcement beam and the inner sill panel. The technical solutions of the sill reinforcement beam assembly, the sill beam, and the vehicle are as follows:

[0005] In a first aspect, the present disclosure provides a threshold reinforcement beam assembly. The threshold reinforcement beam assembly includes a threshold reinforcement beam and a support member. The threshold reinforcement beam includes a bottom plate, a top plate, and a plurality of vertical plates positioned between the bottom plate and the top plate, with a cavity defined between two adjacent vertical plates. The support member is positioned at an end of the threshold reinforcement beam and includes at least one support boss that extends into the cavity and abuts against the vertical plates on either side. The support boss has a first mounting hole, and the vertical plates on either side of the support boss have second mounting holes, with the first mounting hole and the second mounting hole facing each other.

[0006] The sill reinforcement beam can be made of aluminum. It can also be referred to as extruded aluminum, aluminum profile, or extruded aluminum profile. The first and second mounting holes are used to allow connectors to pass through, thereby securing the sill reinforcement beam assembly to the inner sill panel.

[0007] The technical solution provided by the present disclosure connects the rocker reinforcement beam assembly to the rocker inner panel using a connector that passes through a first mounting hole on the support boss and second mounting holes on the risers located on either side of the support boss, thereby connecting the connector to the rocker inner panel. Because the connector passes through at least two risers, the impact force exerted on the rocker reinforcement beam in a small-offset frontal collision is distributed across multiple risers. This reduces the likelihood of the rocker reinforcement beam being torn by the connector and improves the connection strength between the rocker reinforcement beam and the rocker inner panel.

[0008] Furthermore, by providing the support bosses of the support member to support the vertical plates on both sides, it is possible to prevent the vertical plates from being squeezed and deformed by the connecting member during the connection process. In other words, the provision of the support member enables the technical solution of the connecting member passing through at least two vertical plates to be applied in actual projects.

[0009] In one possible implementation, the rocker reinforcement beam assembly includes two support members, one located at each end of the rocker reinforcement beam. This provides greater connection strength between both ends of the rocker reinforcement beam assembly and the rocker inner panel, further improving vehicle safety.

[0010] In a possible implementation, the support member is located at a front end of the sill reinforcement beam, wherein the front end of the sill reinforcement beam is an end close to the front of the vehicle.

[0011] In a possible implementation, the support member is located at a rear end of the sill reinforcement beam, wherein the rear end of the sill reinforcement beam is an end close to the rear of the vehicle.

[0012] In a possible implementation, the support member is an aluminum casting.

[0013] In one possible implementation, the support member includes N support bosses, each of which extends into N cavities of the rocker reinforcement beam. The N cavities are located near a side of the rocker reinforcement beam that contacts the rocker inner panel, and N is greater than or equal to 1. The N cavities are formed between N+1 risers.

[0014] The technical solution provided by the present disclosure, through the above-mentioned arrangement, ensures that the N+1 vertical plates through which the connecting member passes are all supported by the supporting boss or the threshold inner plate. The extrusion force of the connecting member applied to the vertical plates is transmitted to the threshold inner plate via the supporting boss and the vertical plates in sequence. There are no empty cavities in the transmission path, which reduces the possibility of large deformation of each vertical plate and further improves the connection strength between the threshold reinforcement beam and the threshold inner plate.

[0015] In one possible implementation, a rocker reinforcement beam includes M+1 risers, with M cavities defined between the M+1 risers, where M is greater than N. The N+1 risers proximate to the rocker inner panel have second mounting holes, and the M+1 risers distal to the rocker inner panel are separated from the axis of the second mounting holes.

[0016] The MN vertical plates away from the inner sill panel are separated from the axis of the second mounting hole. This means that when a rod-shaped member (such as the aforementioned connector) passes through the second mounting hole and extends through the entire sill reinforcement beam, the rod-shaped member will not interfere with the ends of the MN vertical plates. Alternatively, this means that the MN vertical plates do not block the second mounting hole.

[0017] The technical solution provided by the present disclosure, through the above-described arrangement, ensures that when a connector is inserted through the second mounting holes on the N+1 risers, the MN risers will not interfere with the connector, thereby improving the convenience of connecting the sill reinforcement beam assembly to the sill inner panel. Furthermore, this design reduces the length of the MN risers, thereby reducing the weight of the sill reinforcement beam.

[0018] In a possible implementation, the sill reinforcement beam includes four vertical plates, and three cavities are defined between the four vertical plates. The support member includes two supporting bosses.

[0019] In a possible implementation, the two supporting bosses of the supporting member extend into two cavities of the rocker reinforcement beam close to the rocker inner panel.

[0020] In one possible implementation, the cross-section of the support boss is the same shape as the cross-section of the cavity into which it extends, and the support boss abuts against the bottom plate, top plate, and vertical plates. Thus, after the support boss extends into the cavity, it is restrained by the cavity walls, namely, by the bottom plate, top plate, and vertical plates on both sides. This prevents the support boss from shaking, facilitating the positioning and installation of the support member on the threshold reinforcement beam.

[0021] In a possible implementation, cross sections of the supporting boss and the cavity are both trapezoidal.

[0022] In a possible implementation, cross sections of the supporting boss and the cavity are both rectangular.

[0023] In a possible implementation, the support member further includes a limiting plate, the supporting boss is fixedly connected to the limiting plate, the limiting plate is located outside the cavity and abuts against the end of the door sill reinforcement beam.

[0024] The technical solution provided by the present disclosure provides a limit plate so that the support member will not fully extend into the interior of the cavity. The limit plate plays a role in positioning the support member, which is beneficial to the positioning and installation of the support member on the threshold reinforcement beam.

[0025] In a possible implementation, the support member includes a plurality of support bosses, each of which is fixedly connected to the limiting plate, and a gap is provided between two adjacent support bosses, and the gap is used to accommodate the vertical plate.

[0026] The technical solution provided by the present disclosure integrates multiple supporting bosses together by setting a limiting plate, rather than setting multiple supporting bosses independently of each other, so that the positioning accuracy of the first mounting holes of the multiple supporting bosses is higher, and the connecting parts can smoothly pass through the multiple first mounting holes, thereby improving the convenience of connecting the threshold reinforcement beam assembly and the interior of the threshold.

[0027] In a possible implementation, the four edges of the limiting plate all protrude outward relative to the supporting boss.

[0028] In one possible implementation, the support boss has a third mounting hole, and at least one of the bottom plate and the top plate has a fourth mounting hole. The third mounting hole is opposite the fourth mounting hole, and the third and fourth mounting holes are used to pass a first connecting member through to securely connect the support member to the sill reinforcement beam. The first connecting member is a bolt or a screw. After the support member and the sill reinforcement beam are securely connected, if the sill reinforcement beam tends to move rearward, it will also move the support member backward.

[0029] The technical solution provided by this disclosure, through the provision of the aforementioned third and fourth mounting holes, enables the support member and the sill reinforcement beam to be secured together via connectors. This improves the integrity of the sill reinforcement beam assembly and facilitates its transportation. Furthermore, in small-offset frontal collisions, the impact force on the sill reinforcement beam is distributed among the support member, riser, and top or bottom panels, further reducing the likelihood of the sill reinforcement beam being torn by the connectors and improving the connection strength between the sill reinforcement beam and the inner sill panel.

[0030] In one possible implementation, both the bottom plate and the top plate have fourth mounting holes. This allows the impact force on the sill reinforcement beam to be distributed among the support member, the vertical plate, the top plate, and the bottom plate, further reducing the possibility of the sill reinforcement beam being torn by the connector and improving the connection strength between the sill reinforcement beam and the inner sill plate.

[0031] In a possible implementation, the support member includes a plurality of support bosses, and the support bosses located on both sides of the plurality of support bosses have third mounting holes.

[0032] The technical solution provided by the present disclosure, through the above-mentioned design, firstly, improves the stability of the connection between the support member and the threshold reinforcement beam; secondly, the number of the third mounting holes is two, which reduces the difficulty of positioning the support member on the threshold reinforcement beam and improves the convenience of assembling the threshold reinforcement beam assembly.

[0033] In a possible implementation, the rocker reinforcement beam assembly includes the above-mentioned first connecting member.

[0034] In one possible implementation, the support boss has a weight-reducing hole. The weight-reducing hole is a light hole. Each support boss may have one or more weight-reducing holes. The weight-reducing holes can reduce the weight of the support member, thereby reducing the weight of the entire sill reinforcement beam assembly.

[0035] In a possible implementation, the weight-reducing hole extends along the length direction of the door sill reinforcement beam and passes through the support member.

[0036] In a possible implementation, the weight-reducing hole passes through the supporting boss and the limiting plate.

[0037] In a possible implementation, the first mounting hole intersects with the weight-reducing hole.

[0038] In a possible implementation manner, the first connecting member passes through the weight-reducing hole.

[0039] In a second aspect, the present disclosure provides a threshold beam. The threshold beam includes a threshold inner panel, a threshold reinforcement beam assembly as described in any one of the first aspects, and a second connecting member. The second connecting member is located at an end of the threshold reinforcement beam, passes through a first mounting hole and a second mounting hole, and is connected to the threshold inner panel.

[0040] The rocker panel inner plate is made of steel, such as thermoformed steel. The rocker panel inner plate can be integrally formed with the vehicle body, and can stably support the rocker reinforcement beam. The second connecting member can be a bolt or a screw.

[0041] The technical solution provided by the present disclosure provides a second connector that passes through a first mounting hole in the support boss and second mounting holes in the risers on either side of the support boss, allowing the second connector to pass through at least two risers. This allows the impact force on the sill reinforcement beam to be distributed across multiple risers during a small-offset frontal collision, thereby reducing the likelihood of the sill reinforcement beam being torn by the second connector and improving the connection strength between the sill reinforcement beam and the sill inner panel, thereby increasing the strength of the sill beam.

[0042] Furthermore, by providing the support bosses of the support member to support the vertical plates on both sides, the vertical plates can be prevented from being squeezed and deformed by the second connecting member. In other words, the provision of the support member enables the technical solution of the second connecting member passing through at least two vertical plates to be applied in actual projects.

[0043] In a possible implementation, the sill beam further includes a sill outer panel connected to a sill inner panel, and a receiving cavity is formed between the sill outer panel and the sill inner panel, and the sill reinforcement beam assembly is located in the receiving cavity.

[0044] In a third aspect, the present disclosure provides a vehicle, comprising the sill beam according to any one of the second aspects, wherein the vehicle may be an electric vehicle, a fuel vehicle, or a hybrid vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] like Figure 1 and Figure 2 As shown, in a small-offset frontal collision, one side of the vehicle collides with barrier 300. To ensure vehicle safety, the vehicle's rocker beam 100 must be able to support barrier 300. Otherwise, barrier 300 would squeeze the vehicle's A-pillar 200, causing it to intrude into the cockpit.

[0073] In related technologies, such as Figure 3 As shown, the rocker beam 100 includes a rocker inner panel 1, a rocker reinforcement beam 2, and a rocker outer panel (not shown). The rocker inner panel 1 is integrally formed with the vehicle body. The rocker reinforcement beam 2 includes a bottom panel 21, a top panel 22, and a plurality of vertical panels 23 positioned between the bottom panel 21 and the top panel 22. A cavity 20 is formed between adjacent vertical panels 23. Bolts pass through each vertical panel 23 and connect to the rocker inner panel 1.

[0074] In a small-offset frontal collision, the barrier 300 will exert a significant impact force on the sill reinforcement beam 2 . Furthermore, since the bolts only pass through one riser 23 , the impact force will be borne solely by the single riser 23 . This can easily cause the riser 23 to be torn by the bolts, and the sill reinforcement beam 2 will move backward as a whole, failing to support the barrier 300 .

[0075] In view of the above technical problems, the present disclosure provides a rocker reinforcement beam assembly, such as Figure 4 and Figure 5 As shown, the sill reinforcement beam assembly includes a sill reinforcement beam 2 and a support member 3. The sill reinforcement beam 2 includes a bottom plate 21, a top plate 22, and a plurality of vertical plates 23 positioned between the bottom plate 21 and the top plate 22. A cavity 20 is defined between two adjacent vertical plates 23. The support member 3 is located at the end of the sill reinforcement beam 2 and includes at least one support boss 31. The support boss 31 extends into the cavity 20 and abuts against the vertical plates 23 on either side. The support boss 31 has a first mounting hole 311. The vertical plates 23 on either side of the support boss 31 have second mounting holes 231, with the first mounting hole 311 and the second mounting holes 231 facing each other.

[0076] The material of the door sill reinforcement beam 2 can be aluminum. The door sill reinforcement beam can also be called door sill extruded aluminum, door sill aluminum profile or door sill extruded aluminum profile. The material of the support member 3 can be aluminum, for example, the support member 3 is an aluminum casting. The first mounting hole 311 and the second mounting hole 231 are used for the second connecting member 5 to pass through (such as Figure 6 and Figure 7 As shown), the second connecting member 5 is used to fix the door sill reinforcement beam assembly to the door sill inner panel 1.

[0077] The first mounting hole 311 and the second mounting hole 231 are both clear holes, and the first mounting hole 311 passes through the support member 3 .

[0078] The technical solution provided by the disclosed embodiments connects the rocker reinforcement beam assembly to the rocker inner panel 1 by using a second connector 5 that passes through the first mounting hole 311 on the support boss 31 and the second mounting holes 231 on the risers 23 located on either side of the support boss 31, thereby connecting the second connector 5 to the rocker inner panel 1. Because the second connector 5 passes through at least two risers 23, the impact force exerted on the rocker reinforcement beam 2 in a small-offset frontal collision is dispersed across multiple risers 23, thereby reducing the possibility of the rocker reinforcement beam 2 being torn by the second connector 5 and improving the connection strength between the rocker reinforcement beam 2 and the rocker inner panel 1.

[0079] Furthermore, by providing the support bosses 31 of the support member 3 to support the risers 23 on both sides, it is possible to prevent the risers 23 from being squeezed and deformed by the second connector 5 during the tightening process of the second connector 5. In other words, the provision of the support member 3 enables the technical solution of having the second connector 5 pass through at least two risers 23 to be applied in actual projects.

[0080] The embodiment of the present disclosure does not limit the number of the supporting members 3. In some examples, such as Figure 4 and Figure 5As shown, the rocker reinforcement beam assembly includes two support members 3, which are respectively located at the two ends of the rocker reinforcement beam 2. In this way, the connection strength between the two ends of the rocker reinforcement beam assembly and the rocker inner panel 1 is relatively high, further improving the safety performance of the vehicle.

[0081] In other examples, the support member 3 may be located only at the front end or rear end of the sill reinforcement beam 2. The front end of the sill reinforcement beam 2 is located at the end of the sill reinforcement beam 2 closer to the front of the vehicle, and the rear end of the sill reinforcement beam 2 is located at the end of the sill reinforcement beam 2 closer to the rear of the vehicle.

[0082] Next, the supporting boss 31 included in the supporting member 3 and the cavity 20 into which the supporting boss 31 extends are described in more detail.

[0083] In some examples, such as Figure 3-Figure 20 As shown, the support member 3 includes N supporting bosses 31, each of which extends into N cavities 20 of the rocker reinforcement beam 2. The N cavities 20 are located near the side of the rocker reinforcement beam 2 that contacts the rocker inner panel 1, where N is greater than or equal to 1. Alternatively, the N cavities 20 can be understood as being the first cavity 20, with the cavity 20 adjacent to the rocker inner panel 1 being the first cavity 20, and the N cavities 20 being the first cavity 20 to the Nth cavity 20.

[0084] The technical solution provided by the embodiment of the present disclosure, through the above-mentioned arrangement, ensures that the N+1 vertical plates 23 through which the second connecting member 5 passes are all supported by the supporting boss 31 or the rocker inner panel 1. The extrusion force of the second connecting member 5 applied to the vertical plates 23 is transmitted to the rocker inner panel 1 via the supporting boss 31 and the vertical plates 23 in sequence. There is no empty cavity 20 in the transmission path, which reduces the possibility of large deformation of each vertical plate 23 and further improves the connection strength between the rocker reinforcement beam 2 and the rocker inner panel 1.

[0085] For example, Figure 4-12 As shown, N is 2, and the support member 3 includes two support bosses 31, and the two support bosses 31 extend into the two cavities 20 of the door sill reinforcement beam 2 near the door sill inner plate 1. Figure 10 As shown, after the sill reinforcement beam assembly is connected to the sill inner panel 1, the second connector 5 passes through the two support bosses 31 and the three risers 23. This distributes the impact force on the sill reinforcement beam 2 to at least three risers 23, reducing the possibility of tearing the sill reinforcement beam 2. The three risers 23 near the sill inner panel 1 are provided with second mounting holes 231. Furthermore, having the second connector 5 pass through three risers 23 prevents the second connector 5 from being excessively long due to the second connector 5 passing through too many risers 23.

[0086] For example, Figure 13-15As shown, N is 1, and the support member 3 includes a support boss 31, which extends into the cavity 20 of the sill reinforcement beam 2 near the sill inner plate 1. Figure 13 As shown, the second connecting member 5 passes through a supporting boss 31 and two vertical plates 23. In this way, the impact force on the sill reinforcement beam 2 is distributed to at least the two vertical plates 23, reducing the possibility of tearing of the sill reinforcement beam 2. The two vertical plates 23 near the sill inner panel 1 need to be provided with second mounting holes 231.

[0087] For example, Figure 16-18 As shown, N is 3, the support member 3 includes three support bosses 31, which extend into the three cavities 20 of the door sill reinforcement beam 2 near the door sill inner plate 1 (of course, for Figure 16 , the door sill reinforcement beam 2 also has only three cavities 20). Figure 16 As shown, the second connecting member 5 passes through three supporting bosses 31 and four vertical plates 23. This disperses the impact force on the sill reinforcement beam 2 to at least the four vertical plates 23, reducing the possibility of tearing the sill reinforcement beam 2. The four vertical plates 23 near the sill inner panel 1 are required to be provided with second mounting holes 231.

[0088] In other examples, since the vertical plates 23 abutting against the second connecting member 5 are easily squeezed and deformed by the second connecting member 5 during the tightening process of the second connecting member 5, the support bosses 31 may be provided to only support the vertical plates 23 abutting against the second connecting member 5. In some examples, assuming that the first to the N+1th vertical plates 23 are provided with second mounting holes 231, the support bosses 31 of the support member 3 at least extend into the cavity 20 between the Nth vertical plate 23 and the N+1th vertical plate 23 (i.e., the Nth cavity 20), and the support bosses 31 may or may not extend into the first N-1 cavities 20.

[0089] The embodiment of the present disclosure does not limit the number of vertical plates 23 and cavities 20 included in the rocker reinforcement beam 2. In some examples, the rocker reinforcement beam 2 includes M+1 vertical plates 23, and there are M cavities 20 between the M+1 vertical plates 23. Wherein, M is greater than or equal to N. For example, Figure 4-12 As shown, M is 3 and N is 2. Figure 13-15 As shown, M is 3 and N is 1. Figure 16-Figure 19 As shown, M is 3 and N is 3.

[0090] Of course, the sill reinforcement beam 2 may also include a greater number of risers 23 and cavities 20. For example, if the sill reinforcement beam 2 includes five risers 23 and four cavities 20, the support member 3 may include one, two, three, or four supporting bosses 31. For another example, if the sill reinforcement beam 2 includes six risers 23 and five cavities 20, the support member 3 may include one, two, three, four, or five supporting bosses 31.

[0091] For the case where M is greater than N, such as Figure 6 and Figure 13 As shown, the second connector 5 needs to abut against the riser 23 located in the middle. To prevent interference with the riser 23 that the second connector 5 does not need to pass through, a wedge-shaped structure can be provided at the end of the sill reinforcement beam 2 to expose the second mounting hole 231 on the riser 23 that the second connector 5 needs to abut. This wedge-shaped structure also reduces the weight of the sill reinforcement beam 2.

[0092] The wedge-shaped structure can also be described as follows: the N+1 risers 23 near the rocker inner panel 1 have second mounting holes 231, and the MN risers 23 farther from the rocker inner panel 1 are retracted relative to the second mounting holes 231. The retraction of the MN risers 23 relative to the second mounting holes 231 can be understood as meaning that when a rod-shaped member passes through the second mounting hole 231 and extends throughout the rocker reinforcement beam 2, the rod-shaped member will not interfere with the ends of the MN risers 23. Alternatively, the MN risers 23 are separated from the central axis of the second mounting hole 231.

[0093] For example, Figure 4-12 As shown, M is 3 and N is 2, the three vertical plates 23 close to the rocker inner panel 1 have second mounting holes 231 , and one vertical plate 23 away from the rocker inner panel 1 is retracted relative to the second mounting hole 231 .

[0094] For example, Figure 13-15 As shown, M is 3 and N is 1, the two vertical plates 23 close to the rocker inner panel 1 have second mounting holes 231 , and the two vertical plates 23 away from the rocker inner panel 1 are both retracted relative to the second mounting holes 231 .

[0095] In some examples, such as Figure 10 and Figure 20 As shown, the cross-section of the support boss 31 is the same shape as the cross-section of the cavity 20 into which the support boss 31 extends. The support boss 31 abuts against the bottom plate 21, top plate 22, and vertical plate 23. Thus, after the support boss 31 extends into the cavity 20, it is restrained by the cavity wall 20, preventing it from wobbling within the cavity 20. This facilitates the positioning and installation of the support member 3 on the sill reinforcement beam 2.

[0096] In some examples, such as Figure 10 As shown, the cross-section of the cavity 20 is trapezoidal, and the cross-section of the supporting boss 31 is also trapezoidal.

[0097] In some examples, such as Figure 10 As shown, as the cross-section area of ​​the plurality of cavities 20 gradually decreases in a direction away from the rocker inner panel 1 , the cross-section area of ​​the plurality of supporting bosses 31 also gradually decreases.

[0098] In other examples, such as Figure 20 As shown, the cross section of the cavity 20 is rectangular, and the cross section of the supporting boss 31 is also rectangular.

[0099] In some examples, such as Figure 11-12 、 Figure 14-15 and Figure 17-18 As shown, the support member 3 also includes a stopper plate 32, to which the support boss 31 is fixedly connected. The stopper plate 32 is located outside the cavity 20 and abuts against the end of the sill reinforcement beam 2. The stopper plate 32 and the support boss 31 can be integrally cast. The stopper plate 32 serves to position the support member 3, preventing it from fully extending into the cavity 20.

[0100] In some examples, such as Figure 11-12 and Figure 17-18 As shown, the support member 3 includes a plurality of support bosses 31, each of which is fixedly connected to a limiting plate 32. A gap 33 is defined between two adjacent support bosses 31 to accommodate the riser 23. The limiting plate 32 also serves to connect the plurality of support bosses 31 together, which allows for more precise positioning of the first mounting holes 311 on the plurality of support bosses 31, facilitating the insertion of the second connector 5 through the first mounting hole 311 and the second mounting hole 231.

[0101] Of course, in other examples, the multiple supporting bosses 31 included in the support member 3 can also be separated from each other, and the multiple supporting bosses 31 are not fixed together. Figure 12 The support 3 shown is replaced by two Figure 14 The support member 3 in FIG. For another example, Figure 17 The support 3 shown is replaced by three Figure 14 The support member 3 in.

[0102] In some examples, such as Figure 11-12 、 Figure 14-15 and Figure 17-18 As shown, the support boss 31 has a weight-reducing hole 313. The opening of the weight-reducing hole 313 can reduce the weight of the support boss 31, thereby reducing the weight of the entire door sill reinforcement beam assembly. The weight-reducing hole 313 can be a light hole.

[0103] In some examples, such as Figure 11-12 、 Figure 14-15 and Figure 17-18 As shown, the weight-reducing hole 313 extends along the length direction of the door sill reinforcement beam 2 and passes through the support member 3. For example, when the support member 3 further includes a limiting plate 32, the weight-reducing hole 313 also passes through the limiting plate 32.

[0104] In some examples, such as Figure 4 and Figure 5 As shown, the sill reinforcement beam assembly also includes a first connecting member 4, through which the support member 3 is fixedly connected to the sill reinforcement beam 2. This improves the integrity of the sill reinforcement beam assembly and facilitates its transportation. Furthermore, in a small-offset frontal collision, the impact force on the sill reinforcement beam 2 can be distributed among the support member 3, the vertical plate 23, and the bottom plate 21 and / or top plate 22, further reducing the possibility of tearing of the sill reinforcement beam 2. The first connecting member 4 can be a bolt or a screw. When the sill reinforcement beam 2 moves rearward, it drives the support member 3 with it via the first connecting member 4.

[0105] In some examples, such as Figure 4 、 Figure 13 、 Figure 16 or Figure 19 As shown, the first connecting member 4 passes through the supporting boss 31 and at least one of the bottom plate 21 and the top plate 22. Accordingly, the supporting boss 31 is provided with a third mounting hole 312, and at least one of the bottom plate 21 and the top plate 22 has a fourth mounting hole 221.

[0106] In some examples, such as Figure 4 、 Figure 13 、 Figure 16 or Figure 19 As shown, the first connecting member 4 passes through the bottom plate 21, the support boss 31, and the top plate 22. Accordingly, both the bottom plate 21 and the top plate 22 have fourth mounting holes 221. This distributes the impact force on the sill reinforcement beam across the supporting member 3, the riser 23, the top plate 22, and the bottom plate 21, further reducing the likelihood of the sill reinforcement beam 2 being torn by the second connecting member 5 and improving the connection strength between the sill reinforcement beam 2 and the inner sill panel 1.

[0107] In addition, in the case where the support member 3 includes a plurality of support bosses 31, in order to ensure the stability of the connection between the support member 3 and the rocker reinforcement beam 2, in some examples, such as Figure 16-18 As shown, the two first connecting members 4 respectively pass through two supporting bosses 31 located on both sides of the plurality of supporting bosses 31 to ensure the connection stability between the supporting member 3 and the door sill reinforcement beam 2 .

[0108] Correspondingly, such as Figure 16-18 As shown, the supporting bosses 31 located on both sides of the plurality of supporting bosses 31 have third mounting holes 312 .

[0109] In other examples, such as Figure 19 As shown, the support member 3 includes N support bosses 31, and the N first connecting members 4 pass through the N support bosses 31 respectively. Accordingly, the N support bosses 31 are each provided with a third mounting hole 312. For example, Figure 19 As shown, the support member 3 includes three support bosses 31, and the three first connecting members 4 respectively pass through the three support bosses 31. The three support bosses 31 are each provided with a third mounting hole 312.

[0110] In some examples, the third mounting hole 312 on the support boss 31 is a threaded hole. Figure 11-12 、 Figure 14-15 or Figure 17-18 As shown, the third mounting hole 312 is divided into two sections by the lightening hole 313 , and threads may be provided on only one of the two sections, or on both sections.

[0111] In other examples, the third mounting hole 312 is a smooth hole, and the fourth mounting hole 221 on the bottom plate 21 or the top plate 22 is a threaded hole, and one end of the first connecting member 4 is screwed into the fourth mounting hole 221 .

[0112] In other examples, a nut may also be provided, which is threadedly connected to a portion of the first connecting member 4 that passes through the bottom plate 21 or the top plate 22 .

[0113] In some examples, the rocker reinforcement beam assembly provided by the embodiments of the present disclosure may not include the first connecting member 4 , but may only include the third mounting hole 312 and the fourth mounting hole 221 for the first connecting member 4 to pass through.

[0114] It should be noted that the bolt type and size of the first connecting member 4 and the second connecting member 5 as well as the size of the corresponding mounting holes can be adjusted according to different vehicle models, and are not specifically limited in the embodiment of the present disclosure.

[0115] The embodiment of the present disclosure further provides a threshold beam 100, such as Figure 6-Figure 8 、 Figure 13 、 Figure 16 、 Figure 19 As shown, the threshold beam 100 includes a threshold inner panel 1, the threshold reinforcement beam assembly, and a second connecting member 5. The second connecting member 5 passes through the first mounting hole 311 and the second mounting hole 231 and is connected to the threshold inner panel 1.

[0116] The rocker panel 1 is made of hot-formed steel, which has high strength and can stably support the rocker reinforcement beam 2. The rocker panel 1 can be integrally formed with the vehicle body. The second connecting member 5 can be a bolt or a screw.

[0117] The technical solution provided by the embodiment of the present disclosure is to provide a second connecting member 5 that passes through the first mounting hole 311 on the support boss 31 and the second mounting hole 231 on the vertical plates 23 located on both sides of the support boss 31, so that the second connecting member 5 passes through at least two vertical plates 23. Therefore, in a small offset frontal collision condition, the impact force exerted on the sill reinforcement beam 2 will be dispersed to at least the two vertical plates 23, thereby reducing the possibility of the sill reinforcement beam 2 being torn by the second connecting member 5 and improving the connection strength between the sill reinforcement beam 2 and the sill inner panel 1.

[0118] Furthermore, by providing the support bosses 31 of the support member 3 to support the risers 23 on both sides, it is possible to prevent the risers 23 from being squeezed and deformed by the second connector 5 during the tightening process of the second connector 5. In other words, the provision of the support member 3 enables the technical solution of having the second connector 5 pass through at least two risers 23 to be applied in actual projects.

[0119] In some examples, such as Figure 6 As shown, there are two second connecting members 5 , and the two second connecting members 5 pass through the two supporting members 3 respectively.

[0120] In some examples, such as Figure 8 As shown, a fifth mounting hole 11 is provided on the door sill inner plate 1 , and the fifth mounting hole 11 is used to cooperate with the second connecting member 5 .

[0121] In some examples, the fifth mounting hole 11 is a threaded hole, and the second connecting member 5 is screwed into the fifth mounting hole 11 .

[0122] In other examples, such as Figure 7 As shown, the second connecting member 5 passes through the fifth mounting hole 11 and is threadedly connected to the nut. The fifth mounting hole 11 is a plain hole.

[0123] In some examples, the rocker beam 100 further includes a rocker outer panel connected to the rocker inner panel 1 , and a receiving cavity is formed between the rocker outer panel and the rocker inner panel 1 , in which the rocker reinforcement beam assembly is located.

[0124] The following is an exemplary description of the assembly sequence of the door sill beam provided in the embodiment of the present disclosure.

[0125] First, the support boss 31 of the support member 3 is inserted into the cavity 20 of the rocker reinforcement beam 2. Then, the support member 3 is fixedly connected to the rocker reinforcement beam 2 using the first connector 4, thereby forming the rocker reinforcement beam assembly. Finally, the rocker reinforcement beam assembly is fixedly connected to the rocker inner panel 1 using the second connector 5.

[0126] The embodiment of the present disclosure further provides a vehicle, which includes the above-mentioned door sill beam 100. The vehicle can be an electric vehicle, a fuel vehicle, or a hybrid vehicle.
