The structural strength of the B-pillar is low and its impact resistance is poor. When dealing with a side collision, the B-pillar itself is difficult to bear the impact force of the side collision barrier.

However, the above methods are likely to lead to a significant increase in the mass of the vehicle body frame. At the same time, due to the limited operating space inside the vehicle, the above methods are inconvenient to install and have a poor effect on improving the structural strength of the B-pillar.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] It should be understood that the reference to "some embodiments" throughout the specification means that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the utility model. Therefore, the "in some embodiments" appearing in various places throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0037] The following describes in detail a reinforcement member, a vehicle body frame and a vehicle provided by the utility model by listing specific embodiments.

[0038] Reference Figures 1 to 4 The utility model provides a reinforcement member 4 including a first connection surface 41, wherein the first connection surface 41 is suitable for connecting with a cross beam and a door sill beam respectively.

[0039] Specifically, the vehicle body frame is usually composed of a bottom cross beam, a bottom longitudinal beam, a roof cross beam, a roof longitudinal beam, a door sill beam, a reinforcement beam, an anti-collision beam, an A-pillar, a B-pillar, a C-pillar, a D-pillar, etc. The reinforcement member 4 of the embodiment of the utility model is applied to the design and manufacture of the vehicle body frame. The reinforcement member 4 includes a first connection surface 41, and the first connection surface 41 is suitable for connecting with the cross beam and the door sill beam respectively. Figure 4 As shown in the figure, the cross beam 1 refers to the cross beam under the vehicle, and the threshold beam 2 is located at the bottom of the door and is part of the bottom frame of the vehicle body. The B-pillar includes an inner plate and an outer plate. The inner plate refers to the plate located on the inner side of the B-pillar and is used to support the door and part of the body frame. The outer plate refers to the plate located on the outer side of the B-pillar and is used to support the body contour and protect the parts inside the door. Figure 4As shown, the reinforcement 4 is arranged on the side of the B-pillar inner plate 3 close to the door sill beam 2, and plays a supporting role for the B-pillar. In most models, the side of the B-pillar away from the door sill beam 2 is connected to the upper part of the A-pillar to strengthen the structural stability of the B-pillar, thereby ensuring the stability of the body frame; but in some models, such as convertible models, in order to provide more top vision, the side of the B-pillar away from the door sill beam 2 is not connected to the upper part of the A-pillar. In this case, the structural stability of the B-pillar is poor, the structural strength is low, and the impact resistance is poor. When dealing with the vehicle side collision condition, the B-pillar is easy to encroach too much on the passenger space in the vehicle, causing safety hazards to the passengers.

[0040] In order to improve the structural strength of the B-pillar, in the prior art, the first method is to extend the inner plate of the B-pillar to the inside of the door sill, set the B-pillar reinforcement structure between the inner plate of the B-pillar and the door sill beam, and enhance the strength of the door sill to enhance the structural strength of the bottom of the B-pillar. However, this method easily leads to a significant increase in the mass of the body frame, and at the same time, the improvement of the structural strength of the B-pillar is small, and the structure is relatively complex, which makes the installation of the B-pillar and its reinforcement structure inconvenient. The second method is to use a small thin plate bracket formed by stamping, and use the small thin plate bracket to form a stable triangular structure between the inner plate of the B-pillar, the door sill beam and the floor crossbeam. The small thin plate bracket has a simple structure, but due to the limitation of the stamping method, the thin plate bracket itself needs to reach a certain thickness to have sufficient support capacity. Too large thickness is not conducive to the lightweight design of the whole vehicle. The third method is to set an additional reinforcement plate at the bottom of the inner plate of the B-pillar to enhance the anti-bending ability of the bottom of the B-pillar. However, due to the limited operating space inside the body, the installation of the reinforcement plate is relatively inconvenient, and the structure of the reinforcement plate is generally simple, the structural rigidity is small, and the effect of improving the strength of the B-pillar is not obvious.

[0041] Based on this, the reinforcement 4 of the embodiment of the utility model includes a first connecting surface 41, and the first connecting surface 41 is respectively connected to the cross beam 1 and the door sill beam 2, so that the reinforcement 4 can be supported by the cross beam 1 and the door sill beam 2 at the same time. When subjected to a side collision condition, the force exerted on the B-pillar can be transmitted to the cross beam 1 and the door sill beam 2 respectively through the reinforcement 4, so as to achieve the dispersion and buffering of the force exerted on the B-pillar, thereby effectively improving the impact resistance of the B-pillar and the structural strength of the B-pillar, reducing the intrusion of the B-pillar into the vehicle interior space under side collision conditions, and protecting the lives of passengers.

[0042] Optionally, the reinforcement member 4 further includes a second connecting surface 42 , the second connecting surface 42 and the first connecting surface 41 have an included angle, and the second connecting surface 42 is suitable for connecting to the inner panel of the B-pillar.

[0043] Specifically, the second connection surface 42 intersects with the first connection surface 41. In the embodiment of the utility model, the angle between the second connection surface 42 and the first connection surface 41 is preferably set to be less than 90° to meet the installation requirements of the reinforcement 4 in most vehicle body frames. The second connection surface 42 is connected to the B-pillar inner plate, that is, the reinforcement 4 is fixedly connected to the B-pillar inner plate 3, the cross beam 1 and the threshold beam 2 through the first connection surface 41 and the second connection surface 42 at the same time, so that the connection relationship of the reinforcement 4 is more reliable and the connection stability is higher, so that the reinforcement 4 can provide more reliable support for the B-pillar, and further enhance the structural stability and structural strength of the B-pillar. When the B-pillar outer panel is hit by a side collision, the impact force on the B-pillar outer panel can be transmitted to the second connecting surface 42 of the reinforcement 4 through the B-pillar inner panel 3, and then transmitted to the cross beam 1 and the door sill beam 2 through the first connecting surface 41 of the reinforcement 4, so that the B-pillar can be supported by the cross beam 1 and the door sill beam 2 at the same time, sharing the side impact force on the B-pillar, and transmitting the force of the B-pillar under the side impact condition to the stable bottom of the vehicle body, thereby achieving dispersion and buffering of the force on the B-pillar, effectively improving the impact resistance of the B-pillar, preventing the B-pillar from bending into the vehicle, and further reducing the intrusion of the side impact B-pillar into the vehicle interior space, thereby protecting the lives of passengers.

[0044] According to simulation test, before the reinforcement 4 of the embodiment of the utility model is set on the B-pillar, the tilt angle of the B-pillar of the simulation result Base structure is about 25°~35°, and in most cases it is 30°. After the reinforcement 4 of the embodiment of the utility model is added to the B-pillar, the maximum tilt angle of the B-pillar does not exceed 15°, and in most cases it is 10°. The intrusion amount of the upper side of the B-pillar is reduced from 240mm to about 110mm, which meets the national standard requirement of a maximum of 150mm. The intrusion amount of the lower side of the B-pillar is reduced from 190mm to about 90mm, which meets the national standard requirement of a maximum of 150mm. After analyzing the overall test results, the tilt angle of the B-pillar is reduced by about 20°, the intrusion amount of the upper side of the B-pillar is reduced by about 130mm, and the intrusion amount of the lower side of the B-pillar is reduced by about 100mm, which significantly reduces the intrusion amount of the B-pillar into the interior space under the side collision condition, which helps to protect the lives of passengers.

[0045] Optionally, refer to Figures 1 to 3 The reinforcement 4 also includes a first force transmission surface 43 and a second force transmission surface 44 connected between the first connecting surface 41 and the second connecting surface 42; wherein the B-pillar inner panel 3, the first force transmission surface 43 and the cross beam 1 constitute a first force transmission path, and the B-pillar inner panel 3, the second force transmission surface 44 and the threshold beam 2 constitute a second force transmission path.

[0046] Specifically, the first force transmission surface 43 and the second force transmission surface 44 are connected to each other, and are connected to the first connection surface 41 and the second connection surface 42 respectively. Preferably, the reinforcement member 4 can be processed into an integral structure by an integrated molding process. The reinforcement member 4 of the integral structure is not easy to disperse the force, and the structural stability is better. It can be understood that the first force transmission surface 43, the second force transmission surface 44, the first connection surface 41 and the second connection surface 42 are essentially the surfaces of the reinforcement member 4, wherein the first connection surface 41 and the second connection surface 42 mainly play the role of connecting the reinforcement member 4, and the first force transmission surface 43 and the second force transmission surface 44 mainly play the role of transmitting force and buffering force when the reinforcement member 4 is subjected to force. The B-pillar inner panel 3, the first force transmission surface 43 and the cross beam 1 constitute a first force transmission path, that is, the side collision force received by the B-pillar can be transmitted to the cross beam 1 via the first force transmission surface 43, thereby achieving force dispersion and buffering; the B-pillar inner panel 3, the second force transmission surface 44 and the sill beam 2 constitute a second force transmission path, that is, the side collision force received by the B-pillar can be transmitted to the cross beam 2 via the second force transmission surface 44, thereby achieving force dispersion and buffering.

[0047] Optionally, refer to Figure 2 The second force transmission surface 44 is a triangular structure or a trapezoidal structure.

[0048] Specifically, the second force transmission surface 44 is a triangular structure or a trapezoidal structure. If the second force transmission surface 44 is a triangular structure, the reinforcement 4 formed is similar to a triangular prism. If the second force transmission surface 44 is a triangular structure, the reinforcement 4 formed is similar to a trapezoidal structure. The reinforcements 4 of these two shapes and structures have high stability, are not easily deformed when subjected to force, have strong resistance to bending when subjected to side impact, and can effectively support the B-pillar to prevent the B-pillar from overturning or flipping, thereby providing more reliable support for the B-pillar and helping to improve the structural stability and impact resistance of the B-pillar.

[0049] Optionally, refer to Figure 4 The portion where the first connecting surface 41 is connected to the door sill beam 2 is located on both sides of the first force transmission surface 43 .

[0050] Specifically, if the first connecting surface 41 of the reinforcement 4 and the threshold beam 2 are fixed on one side, that is, the first connecting surface 41 and the threshold beam 2 are connected at only one place, then there is one second force transmission surface 44, and the impact force received by the B-pillar can be transmitted to the threshold beam 2 through the location where the first connecting surface 41 and the threshold beam 2 are connected at one place; if the first connecting surface 41 of the reinforcement 4 and the threshold beam 2 are fixed on both sides, that is, the first connecting surface 41 and the threshold beam 2 are connected at two places, then there are two second force transmission surfaces 44, and the impact force received by the B-pillar can be transmitted to the threshold beam 2 respectively through the locations where the first connecting surface 41 and the threshold beam 2 are connected at two places.

[0051] Preferably, in this embodiment, the first connection surface 41 and the threshold beam 2 are fixed on both sides, and the parts where the first connection surface 41 and the threshold beam 2 are fixedly connected are located on both sides of the first force transmission surface 43. When the impact force on the front side of the B-pillar is large, the force transmitted by the second force transmission surface 44 located on the front side is correspondingly large, and the part where the first connection surface 41 and the threshold beam 2 are fixedly connected on the front side is correspondingly large, so that the component force borne by the threshold beam 2 on the front side is large. Similarly, when the impact force on the rear side of the B-pillar is large, the component force borne by the threshold beam 2 on the rear side is large, wherein the front side of the B-pillar refers to the position of the B-pillar close to the front side of the vehicle head, and the rear side of the B-pillar refers to the position of the B-pillar close to the rear side of the vehicle head. Therefore, in this embodiment, the connection relationship between the reinforcement member 4 and the threshold beam 2 is more stable through the form of fixing the first connection surface 41 and the threshold beam 2 on both sides, which helps to improve the support function of the reinforcement member 4 on the B-pillar, thereby improving the buffering capacity and anti-collision capacity of the B-pillar.

[0052] Optionally, refer to Figures 1 to 3 The reinforcement 4 also includes a first connecting edge 45 and a second connecting edge 46; the first connecting edge 45 is arranged around the outer edge of the first connecting surface 41, and the first connecting surface 41 is connected to the B-pillar inner panel 3 through the first connecting edge 45; the second connecting edge 46 is arranged around the outer edge of the second connecting surface 42, and the second connecting surface 42 is connected to the cross beam 1 and the door sill beam 2 respectively through the second connecting edge 46.

[0053] Specifically, the first connection edge 45 is arranged around the outer edge of the first connection surface 41. The first connection edge 45 and the first connection surface 41 can be welded and fixed, or directly processed into an integral part through an integrated molding process. The first connection edge 45 and the B-pillar inner panel 3 are fixedly connected by welding or assembly connection, which indirectly realizes the fixed connection between the first connection surface 41 and the B-pillar inner panel 3. The second connection edge 46 is arranged around the outer edge of the second connection surface 42. The second connection edge 46 and the second connection surface 42 can be welded and fixed, or directly processed into an integral part through an integrated molding process. The second connection edge 46 is fixedly connected to the cross beam 1 and the threshold beam 2 respectively by welding or assembly connection, which indirectly realizes the fixed connection between the second connection surface 42 and the cross beam 1 and the threshold beam 2. The first connection surface 41 is connected to the B-pillar inner panel 3 through the first connection edge 45, and the second connection surface 42 is fixedly connected to the cross beam 1 and the threshold beam 2 through the second connection edge 46, so that the connection position of the reinforcement 4 and the B-pillar inner panel 3, the cross beam 1 and the threshold beam 2 is more accurate, and the connection relationship is more reliable, while the main structure of the connection surface on the reinforcement 4 is not affected, and the force transmission path is not destroyed. The reinforcement 4 has higher structural strength and stability, and plays a more effective supporting role on the B-pillar.

[0054] Optionally, the first connecting edge 45 is detachably connected to the cross beam 1 and the door sill beam 2 via a fastener 5 , and the second connecting edge 46 is detachably connected to the B-pillar inner panel via a fastener 5 .

[0055] Specifically, a first connection hole for fastener 5 to pass through is provided on the first connection edge 45, a second connection hole for fastener 5 to pass through is provided on the second connection edge 46, a third connection hole is provided at a position corresponding to the first connection hole on the cross beam 1 and the threshold beam 2, and a fourth connection hole is provided at a position corresponding to the second connection hole on the B-pillar inner plate 3, and the fastener 5 includes but is not limited to screws, bolts, rivets, etc. After fastener 5 passes through the first connection hole and the third connection hole, the first connection edge 45 can be detachably connected with cross beam 1 and threshold beam 2, and after fastener 5 passes through the second connection hole and the fourth connection hole, the second connection edge 46 can be detachably connected with the B-pillar inner plate. If the first connection edge 45 and the second connection edge 46 are excessively deformed, resulting in loose connection, the fastener 5 can be loosened, the reinforcement 4 can be disassembled, and the deformed parts of the first connection edge 45 and the second connection edge 46 can be inspected and maintained, or the reinforcement 4 can be replaced to ensure the reliability of the connection between the reinforcement 4 and the B-pillar inner plate 3, the cross beam 1 and the threshold.

[0056] Optionally, the reinforcement member 4 has a hollow cavity.

[0057] Specifically, the interior of the reinforcement member 4 is a hollow structure with a hollow cavity, so that the overall weight of the reinforcement member 4 is relatively light, which is conducive to realizing a lightweight design of the reinforcement member. At the same time, it is more helpful to save consumables and save the processing cost of the reinforcement member 4, thereby achieving cost reduction and efficiency improvement.

[0058] Optionally, refer to Figure 3 The hollow cavity is provided with reinforcing ribs 47 , and the reinforcing ribs 47 are arranged in a direction parallel to the first connecting surface 41 , and / or the reinforcing ribs 47 are arranged in a direction perpendicular to the first connecting surface 41 .

[0059] Specifically, in the embodiment where the reinforcement member 4 has a hollow cavity, a reinforcing rib 47 may be provided in the hollow cavity to ensure the overall structural rigidity of the reinforcement member 4 and prevent the reinforcement member 4 from being deformed by force, which would cause the connection between the reinforcement member 4 and the inner panel 3 of the B-pillar, the cross beam 1 or the door sill beam 2 to fail, and lose the supporting function for the B-pillar. In some preferred embodiments, a plurality of reinforcing ribs 47 may be provided in the hollow cavity of the reinforcement member 4. The plurality of reinforcing ribs 47 may be arranged in a direction parallel to the first connecting surface 41, or in a direction perpendicular to the first connecting surface 41, or may be arranged in a staggered manner horizontally and vertically in the hollow cavity, so that some of the reinforcing ribs 47 are arranged in a direction parallel to the first connecting surface 41, and some of the reinforcing ribs 47 are arranged in a direction perpendicular to the first connecting surface 41. The arrangement method is as follows: Figure 3As shown, a plurality of reinforcing ribs 47 further divide the entire hollow cavity into a plurality of small cavities, thereby increasing the structural density inside the hollow cavity, making the overall structural rigidity of the reinforcing member 4 stronger and reducing the possibility of plastic deformation. At the same time, the reinforcing member 4 of this structure has a strong bending resistance when subjected to a side impact, and can effectively support the B-pillar and prevent the B-pillar from overturning or flipping, thereby ensuring that the reinforcing member 4 can effectively transmit the side impact force borne by the B-pillar.

[0060] Optionally, the reinforcement member 4 is a cast aluminum member.

[0061] Specifically, the aluminum casting process can form complex structures in one piece. Compared with sheet metal parts, aluminum castings have higher strength and fewer processing restrictions, which helps to reduce the processing difficulty of the reinforcement 4 and simplify the processing method. In addition, the mass of aluminum is about one-third of that of steel, which helps to control the overall weight of the reinforcement 4 and further realize the lightweight design of the reinforcement.

[0062] The utility model also provides a vehicle body frame. Figure 5 A schematic diagram of a vehicle body frame in an embodiment of the present utility model is shown, referring to Figure 5 The vehicle body frame includes a cross beam 1, a rocker beam 2, a B-pillar inner panel 3 and any one of the aforementioned reinforcements; the first connecting surface 41 of the reinforcement is connected to the cross beam 1 and the rocker beam 2 respectively; the reinforcement also includes a second connecting surface 42 intersecting with the first connecting surface 41, and the second connecting surface 42 is connected to the B-pillar inner panel 3.

[0063] Specifically, the body frame is an intermediate in the vehicle manufacturing process. It is an assembly structure that welds together various subassemblies such as the floor subassembly, the side panel subassembly, and the engine compartment subassembly to form the vehicle frame. The side panel assembly in the body frame includes a crossbeam 1, a door sill beam 2, a B-pillar inner panel 3, and any of the aforementioned reinforcements 4. The first connection surface 41 of the reinforcement 4 is respectively connected to the crossbeam 1 and the door sill beam 2, and the second connection surface 42 of the reinforcement 4 is connected to the B-pillar inner panel 3. The reinforcement 4 can effectively improve the structural strength of the B-pillar and improve the impact resistance of the B-pillar, so that the body frame has a strong ability to resist side collision impact and high structural stability. In common vehicle models, such as sedans, SUVs, off-road vehicles, etc., the side of the B-pillar 6 away from the door sill beam 2 is connected to the upper part of the A-pillar 7 to ensure the stability of the body frame; but in some models, such as convertibles, sports cars, etc., in order to provide more top vision, the side of the B-pillar 6 away from the door sill beam 2 is not connected to the upper part of the A-pillar 7, and its structure is as follows: Figure 5 As shown, in this case, the stability of the vehicle body frame is poor, and a reinforcement member needs to be provided to strengthen the support for the B-pillar 6, improve the stability of the B-pillar 6, and further ensure the stability of the vehicle body frame.

[0064] The utility model also provides a vehicle, comprising the reinforcing member or the vehicle body frame according to any one of the above embodiments.

[0065] Specifically, vehicles include but are not limited to convertibles, sedans, SUVs, off-road vehicles and other models. Using the reinforcements or body frames of the aforementioned embodiments when manufacturing the vehicles can help improve the vehicle's impact resistance and improve the vehicle's safety.

[0066] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.
