Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a crash beam, a crash beam assembly, and a vehicle. Background Technology

[0002] With the rapid development of diversified safety performance requirements in the automotive industry, the functions and structures of parts such as headlights and grilles at the front of the car are becoming increasingly complex. In order to ensure the proper placement of these functional components at the front of the car, the lateral coverage area of ​​some vehicle anti-collision beams needs to be sacrificed based on the space occupied by these components. In some extreme cases, the two ends of the anti-collision beams are even cut along the height of the vehicle body and flush with the energy-absorbing box. This has an adverse effect on the strength of the entire anti-collision beam and the energy absorption effect of the whole vehicle in the collision condition. Utility Model Content

[0003] The purpose of this application is to solve the aforementioned technical problems by providing a crash beam, a crash beam assembly, and a vehicle, thereby achieving a reasonable installation position to avoid collisions with other components, while simultaneously improving the strength of the crash beam and its energy absorption effect in collision conditions. To achieve the above objectives, the technical solution of this application is as follows:

[0004] In a first aspect, this application provides a crash beam, including a beam body and a reinforcing member; the reinforcing member is disposed at the end of the beam body along a first direction, and the end of the beam body is provided with a plurality of mounting portions along a third direction and / or a second direction, the reinforcing member being connected to at least one mounting portion, and the first direction, the second direction and the third direction intersecting.

[0005] In one possible implementation, the beam body has an inner cavity, which is divided into multiple mounting parts along a third direction and / or along a second direction.

[0006] In one possible implementation, the mounting part has connection ports located at both ends of the beam body along a first direction and / or at both ends of the beam body along a second direction.

[0007] In one possible implementation, the reinforcing member is inserted into the connector and connected to at least a portion of the inner wall of the mounting portion.

[0008] In one possible implementation, at least a portion of the inner wall of the mounting section is provided with reinforcing ribs, and the two ends of the reinforcing ribs along the first direction are aligned with the two ends of the beam body.

[0009] In one possible implementation, a fixing part is provided at the top and / or bottom of the beam body, and the two ends of the fixing part along the first direction are aligned with the two ends of the beam body.

[0010] In one possible implementation, the reinforcing member includes a connecting portion and a reinforcing portion connected together, the connecting portion being connected to the mounting portion, and the reinforcing portion extending in a first direction or a second direction from the end opposite to the connecting portion.

[0011] In one possible implementation, the reinforcing section is provided with energy-absorbing holes.

[0012] Secondly, this application provides a crash beam assembly, including the aforementioned crash beam.

[0013] Thirdly, this application provides a vehicle including the aforementioned anti-collision beam or anti-collision beam assembly.

[0014] Compared with the prior art, the beneficial effects of the anti-collision beam, anti-collision beam assembly, and vehicle of this application are mainly reflected in:

[0015] Multiple mounting parts are provided at the ends of the beam body. Reinforcing members are set to reasonably avoid the positions of functional components according to the arrangement of functional components in the interior space of the vehicle body. The reinforcing members are installed on at least one mounting part arranged along a third direction and / or a second direction on the beam body, so that the reinforcing members can achieve different space utilization effects, making the installation more flexible and convenient. It can also enhance the structural strength of the anti-collision beam and improve the energy absorption effect of the anti-collision beam. When the anti-collision beam is subjected to collision testing, it provides sufficient first-direction support force to the vehicle body during the process of being squeezed by obstacle avoidance. It also increases the lateral sliding force of the anti-collision beam in the early stage of the collision, and the uniformity of the collision obstacle avoidance deformation is good, ensuring the structural effectiveness of the anti-collision beam.

[0025] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0026] Example 1

[0027] This embodiment provides a crash beam, which can be a part of the structure of a vehicle. For example, the vehicle may include longitudinal beams (not shown in the figure), such as a front longitudinal beam. The crash beam can be a front crash beam, which is connected to the front longitudinal beam.

[0028] like Figure 1 As shown, the anti-collision beam includes a beam body 1. The beam body 1 has its width direction defined as a second direction, which can be parallel to the length direction of the vehicle body and parallel to the ground. The beam body 1 has its length direction defined as a first direction, which can be parallel to the width direction of the vehicle body and parallel to the ground. The beam body 1 has its height direction defined as a third direction, which can be parallel to the height direction of the vehicle body and perpendicular to the ground. In some embodiments, the anti-collision beam is installed on the front longitudinal beam, which helps to prevent the front longitudinal beam from being damaged by direct impact. Specifically, the anti-collision beam can be installed at the front end of the front longitudinal beam.

[0029] When a vehicle undergoes a collision test, the anti-collision beam can be crushed to absorb collision energy. The front end of the anti-collision beam along the second direction is the impact surface, and its rear end along the second direction is the support surface. The support surface can be connected to the front longitudinal beam through an energy-absorbing box (not shown in the figure) to achieve the transmission of collision force and continuous energy absorption effect.

[0030] For example, the shape of the anti-collision beam is generally arc-shaped along the first direction, and the cross-section of the anti-collision beam along the second direction is generally rectangular, but it can also be circular or other shapes. In order to avoid insufficient structural strength due to the ends of the anti-collision beam being cut off along the first direction, the anti-collision beam is structurally optimized. At the same time, the anti-collision beam effectively avoids other functional components in the interior space of the vehicle body, which will be specifically explained below.

[0031] like Figures 1-4As shown, the anti-collision beam includes a beam body 1 and a reinforcing member 2; the reinforcing member 2 is disposed at the end of the beam body 1 along the first direction, specifically, the reinforcing member 2 is disposed at both ends of the beam body 1 along the first direction, and the ends of the beam body 1 are provided with a plurality of mounting parts 12 along the second direction and / or the third direction, and the reinforcing member 2 is connected to at least one mounting part 12.

[0032] The first direction, the second direction, and the third direction intersect. The first direction and the third direction can be perpendicular, and the second direction can be perpendicular to the third direction. The first direction can also be an arc, with its tangent perpendicular to the third direction, and the second direction can also be perpendicular to its tangent.

[0033] The beam body 1 includes an upper wall 14, a lower wall 15, and beam sidewalls. The beam body 1 may include two beam sidewalls, specifically, a first beam sidewall 16 and a second beam sidewall 17. The upper wall 14 is located at the top of the beam body 1, and the lower wall 15 is located at the bottom of the beam body 1. Both the upper wall 14 and the lower wall 15 have planar cross-sections. The first beam sidewall 16 is located at the front end of the beam body 1 along the second direction, and the second beam sidewall 17 is located at the rear end of the beam body 1 along the second direction.

[0034] The two beam sidewalls are arranged opposite each other along the second direction, and the distance between the two beam sidewalls can be the same; the cross-sections of the first beam sidewall 16 and the second beam sidewall 17 are both approximately arc-shaped, thus the beam body 1 forms the first direction. The connection between the upper wall 14 and the beam sidewall can be smoothly transitioned, and the connection between the lower wall 15 and the beam sidewall can also be smoothly transitioned.

[0035] For example, the beam body 1 has multiple mounting portions 12 at its ends. Reinforcing members 2 are provided to reasonably avoid the positions of functional components according to their arrangement in the interior space of the vehicle body. The reinforcing members 2 are installed on at least one mounting portion 12 arranged along a third direction and / or a second direction on the beam body 1. For example, the reinforcing member 2 can be installed near the lower wall 15 of the beam body 1, or between the upper wall 14 and the lower wall 15, or near the first beam side wall 16, or near the second beam side wall 17; so that the reinforcing member 2 can achieve different spatial arrangements. The improved design enhances the efficiency of installation, making it more flexible and convenient. It also strengthens the structural strength of the anti-collision beam and improves its energy absorption capacity. During collision tests, when the anti-collision beam is compressed by obstacle avoidance, the reinforcing member 2 absorbs and transfers some of the collision force to the beam body 1 and the energy-absorbing box, allowing the front longitudinal beam to participate in collision energy absorption and providing sufficient first-direction support for the vehicle body. Furthermore, it increases the lateral sliding force of the anti-collision beam in the early stages of a collision, resulting in better uniformity of deformation during collision avoidance and ensuring the structural effectiveness of the anti-collision beam. The connection between the beam body 1 and the reinforcing member 2 avoids material waste caused by partially cutting the anti-collision beam.

[0036] In one embodiment, the beam body 1 has a beam cavity 11, and the beam cavity 11 is divided into a plurality of mounting portions 12 along a third direction and / or along a second direction.

[0037] The mounting section 12 can be understood as a sub-cavity. The beam cavity 11 is divided along a third direction and / or a second direction to form the mounting section 12, creating an effective energy absorption space for the beam cavity 11. Multiple mounting sections 12 can be arranged along a third direction or along a second direction; this enhances the energy absorption effect of the beam body 1 and allows for the adaptation of the reinforcing member 2. The reinforcing member 2 can be selectively connected to the mounting section 12 at a suitable location to meet the different installation position requirements of the reinforcing member 2.

[0038] In one embodiment, the mounting part 12 has a connection port 13 located at both ends of the beam body 1 along a first direction and / or at both ends of the beam body 1 along a second direction.

[0039] The connection port 13 is located at both ends of the beam body 1 along the first direction. It can be understood that the mounting part 12 is provided through both ends along the first direction. The connection port 13 is the opening formed by the end face of the mounting part 12. The reinforcing member 2 can be connected to the connection port 13 of the beam body 1 along the first direction.

[0040] like Figure 5 As shown, the connection ports 13 are located at both ends of the beam body 1 along the second direction, that is, connection ports 13 are respectively provided on the two beam side walls of the beam body 1. The connection ports 13 are connected to the mounting part 12. The reinforcing member 2 can be connected to the connection port 13 at one end of the beam body 1 along the second direction, or it can be connected to the connection port 13 at the other end of the beam body 1 along the second direction, so that the reinforcing member 2 is located on the beam side wall. The above three methods are used to install the reinforcing member 2, providing more options for the installation position of the reinforcing member 2 and making the installation method more flexible.

[0041] In one embodiment, the reinforcing member 2 is inserted into the connection port 13, and the reinforcing member 2 is connected to at least a portion of the inner wall of the mounting part 12.

[0042] The mounting portion 12 has a roughly rectangular cross-section along the second direction, but it can also be circular or other shapes. The outer wall of the reinforcing member 2 corresponds to the shape of the connecting port 13, allowing the reinforcing member 2 to be smoothly inserted into the connecting port 13. When the connecting port 13 is located on the end face of the mounting portion 12 along the first direction, the outer wall of the reinforcing member 2 can be connected to the four inner walls of the mounting portion 12, that is, the reinforcing member 2 is connected to the top wall, bottom wall, and beam side wall of the mounting portion 12 respectively. When the connecting port 13 is located on the end face of the mounting portion 12 along the second direction, the outer wall of the reinforcing member 2 can be connected to the top wall and bottom wall of the mounting portion 12. The connection between the reinforcing member 2 and the inner wall of the mounting portion 12 can be a detachable connection. Specifically, the reinforcing member 2 can be fixed to the inner wall of the mounting portion 12 by screwing or welding. The screwing method ensures the stability of the connection between the reinforcing member 2 and the mounting portion 12 and the convenience of disassembly.

[0043] In one embodiment, at least a portion of the inner wall of the mounting portion 12 is provided with reinforcing ribs 19, and the two ends of the reinforcing ribs 19 along the first direction are aligned with the two ends of the beam body 1.

[0044] The beam cavity 11 is divided into multiple mounting sections 12 along a third direction. The number of mounting sections 12 is adaptively adjusted according to the volume of the beam cavity 11, and can be divided into three mounting sections 12. A coplanar surface 18 is provided between adjacent mounting sections 12, and a reinforcing rib 19 is formed on the coplanar surface 18. The reinforcing rib 19 extends along a first direction to enhance the structural strength and bending resistance of the mounting section 12, thereby improving the strength of the reinforcing member 2 installed in the mounting section 12. The reinforcing rib 19 protrudes relative to the coplanar surface 18, and the reinforcing rib 19 can protrude upwards or downwards. Correspondingly, depending on the volume of the mounting section 12, the number of reinforcing ribs 19 can be one or more, so that the beam body 1 has a continuous force transmission path along the first direction, improving the force transmission efficiency and enhancing the structural strength of the entire beam body 1.

[0045] In one embodiment, a fixing part 31 is provided at the top and / or bottom of the beam body 1, and the two ends of the fixing part 31 along the first direction are aligned with the two ends of the beam body 1.

[0046] The fixing part 31 can be integrally connected with the beam body 1. Specifically, the fixing part 31 is set on the upper wall 14 and lower wall 15 of the beam body 1. The fixing part 31 is set near the side wall 16 of the first beam relative to the beam body 1. The fixing part 31 has a roughly arc-shaped structure so that the fixing part 31 and the beam body 1 maintain the same extension trend, which is conducive to the rapid transmission of collision force and at the same time enhances the impact resistance of the beam body 1.

[0047] In one embodiment, the reinforcing member 2 includes a connecting portion 21 and a reinforcing portion 22 connected together. The connecting portion 21 is connected to the mounting portion 12, and the reinforcing portion 22 extends in a first direction or a second direction away from the end of the connecting portion 21.

[0048] When the connecting part 21 is inserted into the connection port 13 of the beam body 1, the reinforcing part 22 can be extended in different directions according to the space occupied by the functional components in the interior space of the vehicle body. Whether the reinforcing part 22 extends in the first direction or the second direction, it will not affect the installation position of the reinforcing part 22 in the third or second direction, and reasonably avoid the position of the existing functional components in the interior space of the vehicle body. On the basis of ensuring the connection strength between the reinforcing part 2 and the beam body 1, the reinforcing part 22 can have different structural options, which can better adapt to the interior space of the vehicle body according to the actual use.

[0049] In one embodiment, the reinforcing part 22 is provided with energy-absorbing holes 23. The energy-absorbing holes 23 can be through holes, and the number of energy-absorbing holes 23 is rationally arranged according to the volume of the reinforcing part 22. When the reinforcing part 22 is subjected to a collision force, the energy-absorbing holes 23 can effectively absorb the collision energy and deform and collapse. The reinforcing part 22 has angular surfaces 24 in the circumferential direction, which improves the bending resistance of the reinforcing part 22 and optimizes the structure of the reinforcing part 22.

[0051] This embodiment provides a crash beam assembly, including the crash beam and energy-absorbing boxes (not shown in the figure) in the above embodiment. The two energy-absorbing boxes are symmetrically arranged on the beam body 1 along the first direction, specifically, the two energy-absorbing boxes are arranged on the second beam side wall 17 of the crash beam.
