Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicles, and particularly to a sill reinforcement and a vehicle. Background Art
[0002] With the development of new energy vehicles, the demand for increased range has led to heavier vehicle weights. In addition, the market for new energy vehicles is gradually expanding, so vehicles need to meet the legal and regulatory requirements of different regions. Accordingly, the requirements for vehicle safety performance have also been gradually improved to better protect the safety of personnel and vehicle property.
[0003] In a small overlap frontal crash condition, the overlap between the vehicle and the obstacle in the vehicle width direction is only 25%. In an actual collision, the obstacle will hit the front end of the vehicle and the wheels and then hit the A-pillar and the lower sill of the vehicle. If the strength of the A-pillar and the sill is insufficient to resist the impact, the deformation of the vehicle or even the obstacle will enter the cockpit and cause harm to the driver and passengers. Summary of the Utility Model

[0005] In a first aspect of the present application, a sill reinforcement is provided for use in a vehicle. The sill reinforcement extends in a first direction. The sill reinforcement includes a wall body disposed around the first direction and a cavity formed by enclosing the wall body. The sill reinforcement is used to connect the vehicle sill and the inner panel of the A-pillar of the vehicle.
[0006] Further, the cavity extends through the sill reinforcement in the first direction.
[0007] Further, the sill reinforcement further includes: reinforcing ribs disposed in the cavity and connected to the wall body.

Detailed implementation mode
[0025] Here, the technical solutions in the embodiments (or "implementation modes") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0026] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a certain specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.
[0027] Reference Figure 1 , the present application provides a vehicle. For the sake of brevity in description, the present application sets reference directions for the accompanying drawings, namely the first direction X and the second direction Y. The first direction X refers to the length direction of the vehicle. The second direction Y refers to the width direction of the vehicle.
[0028] The vehicle includes a threshold reinforcement 1, a threshold 2, and an inner panel 3 of the A-pillar. The threshold 2 is connected to the bottom of the inner panel 3 of the A-pillar. The threshold reinforcement 1 is respectively connected to the threshold 2 and the inner panel 3 of the A-pillar. The threshold reinforcement 1 is used to strengthen the strength of the inner panel 3 of the A-pillar and the threshold 2.
[0029] When the vehicle is subjected to a small offset collision, the front longitudinal beam 4, the inner panel 3 of the A-pillar, and the threshold 2 of the vehicle are successively impacted by the impact force. If the strength of the inner panel 3 of the A-pillar and the threshold 2 is insufficient, then the body structure of the vehicle will deform towards the driver's cab, causing harm to the passengers and the driver in the driver's cab. The threshold reinforcement 1 is used to strengthen the strength of the inner panel 3 of the A-pillar and the threshold 2, thereby reducing the deformation of the inner panel 3 of the A-pillar and the threshold 2 when they are impacted and improving the safety performance of the vehicle.
[0030] As Figure 2 and Figure 3As shown, the threshold reinforcement member 1 of the present application extends along the first direction X, and includes a wall body 11 disposed around the first direction X and a cavity 12 formed by enclosing the wall body 11. The threshold reinforcement member 1 is used to connect the threshold 2 and the inner panel 3 of the A-pillar. The threshold reinforcement member 1 adopts a closed cavity 12 design, which can ensure good bending resistance and torsional resistance. When the vehicle is subjected to a collision force in the first direction X, the threshold reinforcement member 1 can provide good strength improvement performance, so that the inner panel 3 of the A-pillar and the threshold 2 can better resist the collision and avoid the intrusion of the collision into the interior of the cockpit. At the same time, compared with the reinforcement member structure only connected to the inner panel 3 of the A-pillar, the threshold reinforcement member 1 of the present application connects the threshold 2 and the inner panel 3 of the A-pillar, which can further improve the connection firmness between the threshold 2 and the inner panel 3 of the A-pillar, thereby improving the force resistance and deformation resistance of the threshold 2 and the inner panel 3 of the A-pillar.
[0031] In some embodiments, the cavity 12 extends through the threshold reinforcement member 1 along the first direction X. In this way, the threshold reinforcement member 1 can be produced by an extrusion process. The application of the extrusion process enables designers to flexibly design the outer contour section of the threshold reinforcement member 1 according to the actual space and shape of the vehicle. And the die required for the extrusion process is simple and the development cycle is short, which is beneficial to saving the production cost of the vehicle.
[0032] It should be noted that, in other embodiments, any end face of the threshold reinforcement member 1 in the first direction X can also be a closed cavity 12. The present application does not limit this.
[0033] In an alternative embodiment, the threshold reinforcement member 1 is an aluminum threshold reinforcement member 1. Compared with traditional steel parts, the aluminum threshold reinforcement member 1 is lighter in weight and can also provide sufficient strength supplement. Lightweight materials are beneficial to controlling the overall weight of the vehicle and thus reducing the energy consumption of the vehicle.
[0034] In each embodiment, the threshold reinforcement member 1 may further include a reinforcing rib 13. The reinforcing rib 13 is disposed in the cavity 12 and connected to the wall body 11. The setting of the reinforcing rib 13 can further improve the overall strength of the threshold reinforcement member 1. At the same time, the reinforcing rib 13 is disposed in the cavity 12, which can avoid the need to design other structures to avoid the threshold reinforcement member 1 after the threshold reinforcement member 1 is assembled on the vehicle. The threshold reinforcement member 1 disposed in the cavity 12 can further improve the overall bending resistance and torsional resistance of the annular threshold reinforcement member 1.
[0035] There are multiple ways to set the reinforcing rib 13. For example, the reinforcing rib 13 can be a common triangular rib structure. Or, as shown in the drawings, the reinforcing rib 13 connects the relatively arranged wall bodies 11 in the cavity 12 to isolate the cavity 12 into a plurality of chambers 121 extending along the first direction X. By setting like this, the strength of the threshold reinforcement member 1 as a whole in the second direction Y is improved, thereby improving its overall bending resistance and torsional resistance.
[0036] Further, in some alternative embodiments, the wall body 11 and the reinforcing rib 13 are integrally formed. The integral formation of the wall body 11 and the reinforcing rib 13 not only facilitates processing, but also can improve the strength of the connection position between the wall body 11 and the reinforcing rib 13, thereby further ensuring the overall strength and anti-deformation ability of the sill reinforcement 1. In the embodiment where the reinforcing rib 13 connects the opposite wall bodies 11 within the cavity 12, the reinforcing rib 13 divides the cavity 12 into a plurality of chambers 121 extending along the first direction X, which is also beneficial for the extrusion processing of the sill reinforcement 1 provided with the reinforcing rib 13, further reducing the processing difficulty and cost. In other embodiments, the sill reinforcement 1 can also be formed by die casting, and the present application does not limit this.
[0037] The wall body 11 and the reinforcing rib 13 can also be connected by means such as welding and bonding. In addition, the number of reinforcing ribs 13 can be, as Figure 3 shown, only one is provided, and in the Figure 3 view shown, the cavity 12 is divided into upper and lower chambers 121. In other embodiments, the number of reinforcing ribs 13 can be multiple, and in the Figure 3 view shown, the cavity 12 is divided into front and rear chambers 121. The present application does not limit this either.
[0038] Combined with Figure 3 and Figure 4 , the wall body 11 includes a first wall surface 111 and a second wall surface 112 that are oppositely arranged in the second direction Y. The second wall surface 112 is used to connect with the vehicle. In the embodiment shown in the drawings, the second wall surface 112 is connected to the inner panel 3 of the A-pillar. The sill reinforcement 1 includes a connection hole 14 provided on the second wall surface 112 and an assembly hole 15 provided on the first wall surface 111. The connection hole 14 and the assembly hole 15 are concentric. The provision of the connection hole 14 enables the sill reinforcement 1 and the inner panel 3 of the A-pillar to be detachably connected by fasteners 5 such as screws and bolts. The assembly hole 15 that is concentric with the connection hole 14 facilitates the assembler to extend the assembly tool from the first wall surface 111 into the cavity 12 to disassemble and assemble the fastener 5, reducing the assembly difficulty and improving the production efficiency.
[0039] In other embodiments, the sill reinforcement 1 can be fixedly connected to the inner panel 3 of the A-pillar and the sill 2 by means such as welding. The present application does not limit this.
[0040] Since a plurality of holes are provided on the sill 2 to facilitate the fixed connection with the inner panel 3 of the A-pillar, in order to avoid the difficulty in assembling and disassembling the inner panel 3 of the A-pillar and the sill 2 caused by the assembly of the sill reinforcement 1, in some embodiments, the sill reinforcement 1 further includes an avoidance hole 16. The avoidance hole 16 penetrates the wall body 11 along the second direction Y. Combined with Figure 1 and Figure 2, after the threshold reinforcement member 1 is connected to the inner panel 3 of the A-pillar and the threshold 2, the avoidance hole 16 also allows the assembler to disassemble and assemble the screw structure on the threshold 2 through the avoidance hole 16 without first removing the threshold reinforcement member 1. It can be seen that this setting method can simplify the assembly and repair difficulty of the vehicle.
[0041] It should be noted that the set position and the number of the avoidance holes 16 shown in the drawings should be understood as illustrative rather than restrictive. The designer can design the position of the avoidance hole 16 according to the position of the structure that the threshold reinforcement member 1 needs to avoid. The present application does not limit this.
[0042] In addition, as Figure 1 shown, after the threshold reinforcement member 1 is assembled to the threshold 2 and the inner panel 3 of the A-pillar, it is also necessary to avoid other structural members such as the door. Therefore, as Figure 2 shown, in some embodiments, the end face of the threshold reinforcement member 1 in the first direction X is inclined. The inclined end face enables the threshold reinforcement member 1 to avoid other structures of the vehicle in the first direction X without reducing the size of the threshold reinforcement member 1 in the first direction X. This setting is beneficial to optimizing the overall volume of the threshold reinforcement member 1, and at the same time can ensure the function of increasing the strength provided by the threshold reinforcement member 1.
[0043] The size of the threshold reinforcement member 1 in the first direction X can be selected according to actual needs. It should be understood that if the size of the threshold reinforcement member 1 in the first direction X increases, the strength of the threshold reinforcement member 1 can be improved. Similarly, the size of the threshold reinforcement member 1 in the height direction can also be set according to actual needs, and the larger the size in the height direction, the higher the strength of the threshold reinforcement member 1. Therefore, when space permits, the threshold reinforcement member 1 can be set to fill the vacant area, and the end face in the first direction X can be set to be inclined or the avoidance hole 16 can be provided at the position where other structures need to be avoided.
[0044] It should be noted that the accompanying drawings of the present application are described by taking the threshold reinforcement member 1 being arranged on the threshold 2 and the inner panel 3 of the A-pillar as an example. However, it should be understood that the threshold reinforcement member 1 of the present application can be arranged at different positions of the vehicle to achieve the local strengthening function, and at the same time, different requirements for collision performance can be met by flexibly adjusting features such as the cross-sectional dimension of the cavity 12 in the first direction X, the number of the reinforcing ribs 13, and the wall thickness of the threshold reinforcement member 1.
[0045] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
