Description

[0002] The sill reinforcement beam in the related art is usually connected to the sill beam and the side panel assembly, and mounting holes are respectively provided on opposite sides of the sill reinforcement beam in the left and right directions. The mounting holes of the sill reinforcement beam can be connected and fixed with the sill beam and the side panel assembly by bolts.

[0003] However, in order to ensure that the sill reinforcement beam can play a better anti-collision role in a collision, the upper side of the sill reinforcement beam needs to be close to the upper part of the sill beam in the up and down direction. The sill reinforcement beam is closer to the upper part of the sill beam, which causes the connection point between the sill reinforcement beam and the sill beam to be located higher. The holes on the sill beam are prone to positional interference with the welding area or the glue coating area between the sill beam and the bottom plate. If the lower side of the sill beam is extended downward to increase its size, the size and weight of the sill beam will increase, and it will encroach on the welding and assembly space of the side panel assembly itself, which is not convenient for the welding operation of the side panel assembly.

[0038] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0039] The sill reinforcement beam 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figure 1-Figure 9 As shown, the door sill reinforcement beam 1 according to the embodiment of the utility model includes a reinforcement beam body 100 and a connecting bracket 200 .

[0041] The connecting bracket 200 is connected to the reinforcing beam body 100 and is adjacent to one side of the reinforcing beam body 100 in the left-right direction. The connecting bracket 200 extends downward beyond the lower side of the reinforcing beam body 100 , and is used to connect to the threshold beam 500 .

[0042] It should be noted that usually the side of the sill beam 500 facing the interior of the vehicle, that is, the side of the sill beam 500 facing away from the sill reinforcement beam 1, needs to be welded to the vehicle floor. In order to ensure the sealing after the connection, the sill beam 500 and the floor need to be sealed with glue, that is, at least the part close to the upper side of the sill beam 500 needs to be coated with glue.

[0043] In addition, the side panel assembly 400 is connected to the side of the rocker beam 500 facing the outside of the vehicle, and the rocker reinforcement beam 1 is located between the side panel assembly 400 and the rocker beam 500. The side panel assembly 400 usually includes a side panel and a reinforcement plate, and the lower side of the side panel and the lower side of the reinforcement plate need to be welded. Therefore, the rocker reinforcement beam 1 should not be too close to the lower side of the side panel assembly 400 to reserve operating space for the welding of the side panel and the reinforcement plate.

[0044] The left and right direction of the reinforcing beam body 100 is the left and right direction of the vehicle. The direction indicated by arrow B in the figure is the up and down direction of the vehicle, the direction indicated by arrow C is the left and right direction of the vehicle, and the direction indicated by arrow C is the front and rear direction of the vehicle.

[0045] The reinforcing beam body 100 may be formed by extrusion of metal aluminum, and the connecting bracket 200 may also be formed by extrusion of metal aluminum.

[0046] According to the sill reinforcement beam 1 of the embodiment of the utility model, the sill reinforcement beam 1 is provided with a reinforcement beam body 100 and a connection bracket 200, and the connection bracket 200 is connected to the reinforcement beam body 100 and adjacent to one side of the reinforcement beam body 100 in the left-right direction, and the connection bracket 200 is used to connect with the sill beam 500. For example, the connection bracket 200 can be provided on the side of the reinforcement beam body 100 facing the interior of the vehicle in the left-right direction, so that the connection bracket 200 can be closer to the sill beam 500, so that the sill reinforcement beam 1 is connected and fixed to the sill beam 500 through the connection bracket 200.

[0047] In addition, the connecting bracket 200 extends downwardly beyond the lower side of the reinforcing beam body 100, that is, the height of the connecting bracket 200 can be lower than the lower side of the reinforcing beam body 100, that is, the height of the connecting bracket 200 can be lower, so that the hole position on the threshold beam 500 for connecting with the connecting bracket 200 can be set lower, thereby avoiding the welding area between the threshold beam 500 and the floor or the hole position on the threshold beam 500 for connecting with the connecting bracket 200 being covered by glue.

[0048] Moreover, by providing the connecting bracket 200, the reinforcement beam body 100 can be connected to the position near the lower part of the threshold beam 500 without extending downward. This arrangement can not only make the size of the reinforcement beam body 100 smaller in the upper and lower directions to avoid the excessive volume of the threshold reinforcement beam 1, which is beneficial to reducing the weight of the threshold reinforcement beam 1 and facilitating layout and installation, but also the space between the lower side of the reinforcement beam body 100 and the lower side of the side panel assembly 400 can be larger, so that the operating space is more sufficient when welding and assembling the side panel assembly 400, and the operation is more convenient.

[0049] In this way, the connection point between the sill reinforcement beam 1 and the sill beam 500 according to the embodiment of the utility model can be lower, and the size of the sill reinforcement beam 1 will not be too large, so the layout and assembly are more convenient.

[0050] In some specific embodiments of the present invention, Figure 4 , Figure 8 and Fig. 9 As shown, the connecting bracket 200 includes a main body 210, a first connecting portion 220 and a second connecting portion 230.

[0051] The main body 210 extends downwardly beyond the lower side of the reinforcing beam body 100, and the main body 210 is connected to the threshold beam 500. The first connection portion 220 is connected to the main body 210 and to one side of the reinforcing beam body 100 in the left-right direction. For example, the first connection portion 220 can be connected to one side of the reinforcing beam body 100 in the left-right direction facing the threshold beam 500, and the second connection portion 230 is connected to the main body 210 and to the lower side of the reinforcing beam body 100.

[0052] The first connection portion 220 and the second connection portion 230 can be welded to the reinforcing beam body 100. For example, the first connection portion 220 and the second connection portion 230 can be welded to the reinforcing beam body 100 by two-way welding. Of course, in other embodiments, the first connection portion 220 and the second connection portion 230 can also be connected to the reinforcing beam body 100 by fasteners.

[0053] With this arrangement, the first connection portion 220 and the second connection portion 230 can be connected to different sides of the reinforcement beam body 100 respectively, and the connection area between the connection bracket 200 and the reinforcement beam body 100 can be larger, which is beneficial to improving the connection strength between the connection bracket 200 and the reinforcement beam body 100, so that the overall structural strength of the threshold reinforcement beam 1 is higher, and the connection between the threshold reinforcement beam 1 and the threshold beam 500 can be more stable and reliable.

[0054] Furthermore, if Figure 8 and Fig. 9 As shown, the main body 210 includes a first plate body 211 , a second plate body 212 and a third plate body 213 .

[0055] The upper end of the first plate body 211 is connected to the first connecting portion 220, the first plate body 211 is connected to the door sill beam 500, the second plate body 212 extends in the left-right direction, and one end of the second plate body 212 is connected to the lower end of the first plate body 211, the lower end of the third plate body 213 is connected to the other end of the second plate body 212, and the upper end of the third plate body 213 is connected to the second connecting portion 230.

[0056] Among them, the main body 210 is connected to the threshold beam 500 through the first plate body 211. For example, a fastener can be used to pass through the threshold beam 500 and the first plate body 211 to fix the relative position of the connecting bracket 200 and the threshold beam 500, thereby realizing the connection and fixation of the threshold reinforcement beam 1 and the threshold beam 500. In addition, the first plate body 211 and the second plate body 212 can be arranged at intervals, so that the fastener will not interfere with the second plate body 212 after passing through the first plate body 211, which is convenient for assembly.

[0057] In addition, the first plate 211 can extend in the up-down direction, or, when the side wall of the door sill beam 500 has a certain angle with the vertical direction, the first plate 211 can also be tilted relative to the up-down direction, so that the first plate 211 can fit tightly with the side wall of the door sill beam 500, and the connection is more stable and reliable.

[0058] In addition, the first plate 211 extends beyond the side of the reinforcing beam body 100 facing the threshold beam 500 in the left-right direction. In this way, the first plate 211 can be closer to the threshold beam 500, so that the connecting bracket 200 can be connected and fixed through the first plate 211 and the threshold beam 500.

[0059] Moreover, it is understandable that Figure 2 As shown, usually the space near the side wall of the threshold beam 500 in the up and down direction is smaller. By extending the first plate 211 beyond the reinforcing beam body 100 toward the direction close to the threshold beam 500, the reinforcing beam body 100 does not need to extend to abut against the side wall of the reinforcing beam, and the assembly space is more sufficient.

[0060] In some specific embodiments of the present invention, Figure 8 As shown, the first connecting portion 220 includes a first bending plate 221 and a second bending plate 222 .

[0061] The first bending plate 221 is attached to and connected to the reinforcing beam body 100 , the second bending plate 222 is connected to the first bending plate 221 and bent relative to the first bending plate 221 , and one end of the second bending plate 222 away from the reinforcing beam body 100 is connected to the upper end of the first plate body 211 .

[0062] In this way, on the one hand, the first bent plate 221 can be fitted with the reinforcing beam body 100, the contact area between the first bent plate 221 and the reinforcing beam body 100 can be larger, and the connection can be more stable and reliable; on the other hand, the second bent plate 222 can be extended toward the direction close to the threshold beam 500, and the first plate body 211 can be closer to the threshold beam 500 than the reinforcing beam body 100, so as to facilitate the connection between the first plate body 211 and the threshold beam 500.

[0063] In some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, the connecting bracket 200 further includes a rivet 240 .

[0064] The first plate body 211 is configured with a first mounting hole 214 . The rivet 240 is passed through the first mounting hole 214 and riveted to the first plate body 211 . The rivet 240 is screwed to the door sill beam 500 via a first fastener.

[0065] For example, the rivet 240 can be a rivet nut, and the inner wall of the rivet 240 can be provided with an internal thread. After the rivet 240 is inserted into the first mounting hole 214, the rivet 240 can be riveted and fixed to the first plate 211, and then the rivet 240 is matched with the hole position on the threshold beam 500, and the threshold beam 500 and the rivet 240 are connected and fixed by the first fastener, thereby realizing the connection and fixation of the threshold beam 500 and the threshold reinforcement beam 1.

[0066] It is understandable that, in some embodiments, a threaded hole may be directly constructed on the connecting bracket 200 , and then the connecting bracket 200 is directly connected to the door sill beam 500 via a first fastener.

[0067] In addition, in some embodiments, a 2.5 mm gap may be reserved between the side wall bracket connecting the bracket 200 and the threshold beam 500, or a 0.7 mm gap may be reserved between the countersunk head of the first fastener and the side wall of the threshold beam 500 to absorb assembly errors and ensure smooth assembly between the threshold reinforcement beam 1 and the threshold beam 5200.

[0068] In some specific embodiments of the present invention, Figure 5 As shown, there are multiple connecting brackets 200, and the multiple connecting brackets 200 are arranged at intervals along the length direction of the reinforcement beam body 100. By providing multiple connecting brackets 200, it is beneficial to improve the connection strength between the threshold reinforcement beam 1 and the threshold beam 500, and the connection is more stable and reliable.

[0069] There may be 7 to 10 connecting brackets 200, for example, there may be 7, 8, 9 or 10 connecting brackets 200. In addition, the multiple connecting brackets 200 may be evenly spaced along the length direction of the reinforcing beam body 100, or the spacing between some adjacent connecting brackets 200 in the multiple connecting brackets 200 may be the same, and the spacing between another part of the connecting brackets 200 in the multiple connecting brackets 200 may be different.

[0070] In some specific embodiments of the present invention, one end of the reinforcement beam body 100 is suitable for extending to below the front pillar, and the other end of the reinforcement beam body 100 is suitable for extending to below the rear pillar.

[0071] Among them, the front pillar is the A-pillar of the vehicle, and the rear pillar can be the C-pillar of the vehicle. By extending the reinforcement beam body 100 to the bottom of the A-pillar and the C-pillar respectively, when the vehicle collides, the door sill reinforcement beam 1 can support the A-pillar and the C-pillar, and at the same time, the force of the front of the A-pillar can be transmitted to the rear uncollided area through the door sill reinforcement beam 1 to ensure the integrity of the passenger compartment, and can reduce the force on the battery module, effectively improving the collision safety of the vehicle.

[0072] In some specific embodiments of the present invention, Figure 6 As shown, a plurality of second mounting holes 110 are provided on the other side of the reinforcing beam body 100 in the left-right direction. The plurality of second mounting holes 110 are arranged at intervals along the length direction of the reinforcing beam body 100 , and the second mounting holes 110 are suitable for being connected to the side enclosure assembly 400 through a second fastener.

[0073] Among them, a plurality of welding brackets 410 can be welded and connected to the side of the side panel assembly 400 facing the door sill reinforcement beam 1, and the plurality of welding brackets 410 and the plurality of second mounting holes 110 are connected one by one through second fasteners, thereby realizing the connection and fixation of the door sill reinforcement beam 1 and the side panel assembly 400.

[0074] In addition, the second mounting holes 110 and the welding brackets 410 can be set to 6 to 8, for example, the second mounting holes 110 and the welding brackets 410 can be 6, 7 or 8. By setting a plurality of welding brackets 410 and a plurality of second mounting holes 110 in one-to-one connection, it is beneficial to improve the connection strength between the sill reinforcement beam 1 and the side panel assembly 400, and the connection is more stable and reliable.

[0075] In addition, an asbestos gasket may be bonded to the side of the welding bracket 410 facing the threshold reinforcement beam 1 to separate the welding bracket 410 from the threshold reinforcement beam 1 to avoid electrophoretic corrosion caused by direct contact between the threshold reinforcement beam 1 and the bracket.

[0076] In some specific embodiments of the present invention, Figure 5-Figure 8 As shown, the reinforcement beam body 100 is provided with a plurality of electrophoretic holes 120, and the plurality of electrophoretic holes 120 penetrate the reinforcement beam body 100. For example, the peripheral wall of the reinforcement beam body 100 may be provided with a plurality of electrophoretic holes 120, and the side wall inside the reinforcement beam body 100 may also be provided with electrophoretic holes 120. By providing the electrophoretic holes 120, when the threshold reinforcement beam 1 is electrophoretically plated, the electrophoretic liquid may flow through the electrophoretic holes 120, so that the electrophoretic liquid may flow to multiple positions of the reinforcement beam body 100, thereby avoiding the problem of insufficient electrophoretic plated film thickness and making the plated film more uniform.

[0077] In addition, the electrophoresis hole 120 can be spaced apart from the connecting bracket 200 and the second mounting hole 110, so as to avoid the electrophoresis hole 120 causing a decrease in the structural strength near the connecting bracket 200 and the second mounting hole 110, thereby ensuring that the structural strength of the reinforcing beam body 100 is higher and the anti-collision performance is better.

The vehicle includes a side panel assembly 400 , a rocker beam 500 , and a rocker reinforcement beam 1 according to the above embodiment of the present invention.

[0079] The sill beam 500 is connected to the side panel assembly 400 , and the sill beam 500 and the side panel assembly define a cavity 510 . The sill reinforcement beam 1 is disposed in the cavity 510 and is connected to the side panel assembly 400 and the sill beam 500 , respectively.

[0080] Among them, the side panel assembly 400 may include a side panel and a reinforcement plate, the side panel is arranged on the outer side of the reinforcement plate and is welded to the reinforcement plate, a cavity 510 may be defined between the reinforcement plate and the threshold beam 500, and a plurality of welding brackets 410 are welded to the side of the reinforcement plate facing the threshold reinforcement beam 1, the side panel assembly 400 is connected and fixed to the threshold reinforcement beam 1 by the plurality of welding brackets 410, and the threshold reinforcement beam 1 is connected to the threshold beam 500 by the connecting bracket 200, so that the side panel assembly 400, the threshold reinforcement beam 1 and the threshold beam 500 can be connected into a whole.
