[0041] In the related art, a triangular window is opened in the A-pillar of a vehicle to reduce the visual blind area during driving. To enhance the structural strength at the triangular window of the A-pillar, in some existing technologies, the A-pillar adopts a combination of metal and non-metal materials in order to have both lightweight and strength. However, the bonding strength between the metal and non-metal materials is poor, resulting in the situation that when the A-pillar is subjected to shear force, the metal material cannot play a role in strengthening the structure, and even the non-metal material may be torn, and the metal reinforcement plate may directly separate from the A-pillar without deformation, etc., and the overall vehicle safety performance is low.

[0042] Reference will be made below to Figures 1-5 describe the connection assembly 100 for a vehicle body according to an embodiment of the present utility model.

[0043] As Figure 3As shown in the figure, the connecting component 100 for a vehicle body according to the present utility model includes: a first component 1 and a second component 2. A protrusion 14 is formed on the outer surface of the first component 1; the second component 2 is disposed on the outer surface of the first component 1 and a hole 2a is formed on the second component 2, and the hole 2a is adapted to receive the protrusion 14. Here, to ensure the effective connection between the first component 1 and the second component 2, the protrusion 14 is designed on the outer surface of the first component 1, and the hole 2a is designed on the second component 2. The first component 1 and the second component 2 are connected together through the cooperation of the protrusion 14 and the hole 2a, and a connecting component 100 for a vehicle body with high shear strength and suitable for bearing shear working conditions can be formed. The bonding strength between the materials of the connecting component 100 is good, and the separation between the materials is not likely to occur.

[0044] The connecting component 100 designed according to the present utility model can be applied to the position where the body 1000 needs to strengthen the structural strength according to the actual situation, and the installation position of the connecting component 100 on the body 1000 is not limited herein.

[0045] In some embodiments, the connecting component 100 can be applied to the triangular window structure of the A-pillar. In the small offset collision condition, the collision force is transmitted from the front passenger compartment to the A-pillar triangular window structure. The A-pillar triangular window structure mainly bears the shear force, and the performance requirements at this place are high. When the connecting component 100 is disposed at this place, when the A-pillar triangular window structure is subjected to the shear force, the protrusion 14 abuts against the inner wall of the hole 2a, which can limit the relative movement between the first component 1 and the second component 2, and can also transmit the shear force to the second component 2 or the first component 1 when the first component 1 or the second component 2 is subjected to an external force. The design of the protrusion 14 and the hole 2a makes the bonding strength between the first component 1 and the second component 2 high and not easy to separate, so that the entire connecting component 100 has higher shear resistance, and further improves the shear resistance of the A-pillar triangular window structure.

[0046] Among them, the first component 1 is made of a metal material, and the second component 2 is made of a non-metallic composite material. Since the first component 1 and the second component 2 are made of different materials, to ensure the effective connection between the first component 1 and the second component 2, the protrusion 14 is designed on the outer surface of the first component 1 made of a metal material, and the hole 2a is designed on the second component 2 made of a non-metallic composite material. The first component 1 and the second component 2 are connected together through the cooperation of the protrusion 14 and the hole 2a, and a connecting component 100 for a vehicle body with high shear strength and suitable for bearing shear working conditions can be formed. The bonding strength between the materials of the connecting component 100 is good, and the separation between the materials is not likely to occur.

[0047] According to the connecting component 100 for a vehicle body of the present utility model, its first component 1 and second component 2 are connected together through the cooperation of the protrusion 14 and the hole body 2a, so that the bonding strength between dissimilar materials is high, separation is not likely to occur, the overall shear resistance is strong, and the dual requirements of vehicle lightweight and high performance can be met under shear conditions.

[0048] In some embodiments, the first component 1 can be made of hot-formed steel or other metal materials, and the weight of the first component 1 can be adjusted by changing the material selection of the first component 1.

[0049] In some embodiments, the second component 2 can be made of non-metallic composite materials such as thermosetting long carbon fiber composites, thermoplastics, and glass fibers, and the cost of the second component 2 can be adjusted by changing the material selection of the second component 2.

[0050] In some embodiments, multiple second components 2 can be provided on the first component 1, and multiple first components 1 can also be provided on the second component 2. The specific arrangement form of the first component 1 and the second component 2 can be selected according to actual needs.

[0051] According to some embodiments of the present utility model, as Figure 3 shown, second components 2 are respectively provided on both sides of the first component 1 in the thickness direction, and both sides of the first component 1 are respectively fixed to the second components 2. Specifically, two second components 2 can be provided on the first component 1 to form a multi-layer structure, and adjacent layers in the multi-layer structure are fitted and connected to each other to improve the anti-collision ability at the vehicle body 1000 where the connecting component 100 is provided.

[0052] According to some embodiments of the present utility model, as Figure 3 shown, the second component 2 is configured as two, namely an inner plate 21 and an outer plate 22, at least part of the inner plate 21 and the outer plate 22 are spaced apart to define a receiving cavity, and the first component 1 is arranged in the receiving cavity. Specifically, the inner plate 21 and the outer plate 22 form a receiving cavity suitable for receiving the first component 1. At this time, protrusions 14 are provided on both surface sides of the first component 1 in the thickness direction, and the inner plate 21 and the outer plate 22 are respectively located on both sides of the first component 1 in the thickness direction.

[0053] In some embodiments, the outer plate 22 is located on the outside of the multi-layer structure formed by the first component 1 and the second component 2, the inner plate 21 is located on the inside of the multi-layer structure, and the first component 1 is located in the middle layer. A large number of non-metallic composite materials are used in this connecting component 100. Since the density of non-metallic composite materials is generally less than that of metal materials, compared with the strengthening structure made of pure metal materials, the connecting component 100 designed according to the present utility model is more lightweight.

[0054] According to some embodiments of the present utility model, the first component 1 is formed with a first reinforcing protrusion protruding away from the outer plate 22, the inner plate 21 is formed with a second reinforcing protrusion 211 protruding away from the outer plate 22 and corresponding to the first reinforcing protrusion, a groove is formed on the surface of the second reinforcing protrusion 211 facing the outer plate 22, a partial accommodation cavity is defined inside the groove, and the first reinforcing protrusion is received in the groove. Specifically, the inner plate 21 is formed with a second reinforcing protrusion 211 protruding away from the outer plate 22, and the first component 1 is formed with a first reinforcing protrusion protruding away from the outer plate 22. A groove is formed on the surface of the second reinforcing protrusion 211 facing the outer plate 22, and the first reinforcing protrusion is received in the groove.

[0055] In some embodiments, as Figure 3 shown, when the connection assembly 100 is applied to the triangular window structure of the A-pillar, the cross-section of the inner plate 21 in the height direction is "ji" shaped, and the cross-section of the outer plate 22 in the height direction is "one" shaped. The two are connected to define a closed accommodation cavity, and this structure can effectively improve the stiffness and sectional force of the connection assembly 100 under the load in the height direction.

[0056] In some embodiments, the first component 1 is disposed in the accommodation cavity. The first reinforcing protrusion protruding on the first component 1 forms a cavity. The first component 1 located between the inner plate 21 and the outer plate 22 can enhance the structural strength of the inner plate 21 and the outer plate 22, and the first reinforcing protrusion protruding on the first component 1 can further improve the structural strength of the first component 1.

[0057] According to some embodiments of the present utility model, as Figure 3 shown, the first component 1 includes a first section 11, a second section 12 and a third section 13. The first section 11 and the second section 12 extend along the extension direction of the outer plate 22. The first section 11 and the second section 12 are spaced apart in the extension direction of the outer plate 22. The surfaces of the first section 11 and the second section 12 facing the outer plate 22 and the surfaces facing the inner plate 21 are both formed with protrusions 14. The third section 13 is disposed between the first section 11 and the second section 12 and is respectively connected to the first section 11 and the second section 12. The third section 13 is spaced apart from the outer plate 22 and protrudes in the direction away from the outer plate 22 to form a first reinforcing protrusion, and the surface of the third section 13 facing the inner plate 21 is formed with a protrusion 14. Specifically, the surfaces of the first section 11 and the second section 12 of the first component 1 facing the outer plate 22 are formed with protrusions 14 to connect the first component 1 with the outer plate 22. The surfaces of the first section 11, the second section 12 and the third section 13 of the first component 1 facing the inner plate 21 are formed with protrusions 14 to connect the first component 1 with the inner plate 21. At this time, the end face of the first component 1 is "ji" shaped, which can enhance the structural strength of the first component 1 and improve the force-bearing capacity of the first component 1.

[0058] In some embodiments, when the connecting component 100 is applied to the triangular window structure of the A-pillar, the top of the A-pillar is generally connected to the roof reinforcement beam of the vehicle body 1000, and the bottom of the A-pillar is generally connected to the sill beam of the vehicle body 1000. In the top pressing condition, the force is transmitted from the roof reinforcement beam to the triangular window structure of the A-pillar and then to the sill, forming a force transmission path in the height direction. At this time, the triangular window structure of the A-pillar is mainly subjected to the force in the height direction. Designing the cross-sections of the inner panel 21 and the first component 1 in the height direction as a "ji" shaped structure can effectively improve the stiffness and sectional force of the connecting component 100 under the load in the height direction.

[0059] According to some embodiments of the present invention, as Figure 5 shown, the protrusion 14 extends in the thickness direction of the second component 2 and has a length of d1 in the extending direction. The cross-sectional thickness of the second component 2 at the position where the protrusion 14 is received is d2, and it satisfies: d2 > d1. Specifically, here, the protrusion 14 is provided on the first component 1. When the protrusion 14 cooperates with the hole body 2a, the length of the protrusion 14 needs to be not greater than the depth of the hole body 2a, that is to say, the length of the protrusion 14 needs to satisfy being less than the thicknesses of both the inner panel 21 and the outer panel 22 simultaneously, so as to prevent the protrusion 14 from penetrating the second component 2, thereby ensuring the effective connection between the protrusion 14 and the second component 2.

[0060] According to some embodiments of the present invention, both the protrusion 14 and the hole body 2a are configured as multiple, and at least one of the multiple protrusions 14 cooperates with at least one of the multiple hole bodies 2a. In some embodiments, the number of the protrusions 14 is not more than the number of the hole bodies 2a to ensure that each protrusion 14 can be received in the hole body 2a. The cooperation of the multiple protrusions 14 and the multiple hole bodies 2a can increase the contact area between the first component 1 and the second component 2, thereby increasing the frictional force between the first component 1 and the second component 2 and further strengthening the bonding strength between the first component 1 and the second component 2.

[0061] In some embodiments, the thicknesses at different positions of the second component 2 can be different. Each protrusion 14 cooperates with the corresponding hole body 2a, and the length of the protrusion 14 corresponding to the hole body 2a at the thicker part of the second component 2 can also be longer, which can be designed according to the actual situation.

[0062] In some embodiments, the second component 2 is made of a carbon fiber composite material.

[0063] According to some embodiments of the present invention, as Figure 4As shown, the second component 2 includes a first carbon fiber bundle 23 and a second carbon fiber bundle 24. The first carbon fiber bundle 23 extends in a first direction. The first carbon fiber bundle 23 is configured to be multiple, and multiple first carbon fiber bundles 23 are arranged at intervals in a second direction, and the second direction intersects the first direction; the second carbon fiber bundle 24 extends in the second direction. The second carbon fiber bundle 24 is configured to be multiple, and multiple second carbon fiber bundles 24 are arranged at intervals in the first direction, and the second carbon fiber bundle 24 is overlapped and woven with the first carbon fiber bundle 23; two first carbon fiber bundles 23 are arranged at intervals to form a first gap, and two second carbon fiber bundles 24 are arranged at intervals to form a second gap, and a hole 2a is formed at the overlapping position of the first gap and the second gap.

[0064] Specifically, when an external force acts on the connection assembly 100, there may be a tendency of relative movement between the first component 1 and the second component 2. To prevent relative movement between the first component 1 and the second component 2, the protrusion 14 is embedded between the first carbon fiber bundle 23 and the second carbon fiber bundle 24 of the second component 2. When an external force acts on the connection assembly 100, the protrusion 14 will contact the first carbon fiber bundle 23 and the second carbon fiber bundle 24. At this time, the first carbon fiber bundle 23 and the second carbon fiber bundle 24 block the continuous movement of the protrusion 14, thereby reducing the tendency of relative movement between the first component 1 and the second component 2.

[0065] And it can be understood that, compared with the second component 2 made of a non-metallic composite material, the first component 1 made of a metal material has better shear resistance. After the outer plate 22 in the second component 2 is stressed, the force can be transmitted to the protrusion 14 through each carbon fiber bundle, and then transmitted to the first component 1, so that the whole structure has high shear resistance. At the same time, through the interaction between the protrusion 14 and the first carbon fiber bundle 23 and the second carbon fiber bundle 24, the bonding force between the first component 1 and the inner plate 21 and the outer plate 22 is greatly improved, and the bonding strength between dissimilar materials is improved.

[0066] In some embodiments, the protrusions 14 are configured to be multiple, and multiple protrusions 14 are evenly distributed on the outer surface of the first component 1.

[0067] According to some embodiments of the present invention, the projection of the protrusion 14 in the thickness direction of the second component 2 is located within the projection of the hole 2a in the thickness direction of the second component 2. Here, the hole 2a can accommodate the protrusion 14 to ensure the dimensional assembly and effective connection of the protrusion 14 with the inner plate 21 and the outer plate 22.

[0068] According to some embodiments of the present invention, such as Figure 4As shown, the distance between two adjacent hole bodies 2a is b1, the width of the first carbon fiber bundle 23 is b2, and the width of the second carbon fiber bundle 24 is b3, satisfying: b1 > b2 and b1 > b3. Specifically, the distance between two adjacent hole bodies 2a is greater than the diameters of the first carbon fiber bundle 23 and the second carbon fiber bundle 24. Correspondingly, the distance between two adjacent protrusions 14 is also greater than the diameters of the first carbon fiber bundle 23 and the second carbon fiber bundle 24, ensuring that each protrusion 14 does not penetrate into the first carbon fiber bundle 23 and the second carbon fiber bundle 24, and preventing the protrusions 14 from damaging the first carbon fiber bundle 23 and the second carbon fiber bundle 24.

[0069] According to some embodiments of the present invention, as Figure 3 shown, the diameter of the protrusion 14 gradually decreases in the direction away from the first component 1. In some embodiments, the protrusion 14 is conical and evenly distributed on the first component 1, and the distribution range is consistent with the shape of the first component 1.

[0070] In some embodiments, the protrusion 14 can also adopt other distribution densities, diameters, and different shapes and sizes of features with heights.

[0071] In some embodiments, when manufacturing the connection assembly 100, the protrusion 14 can be first manufactured on the outer surface of the first component 1. The first component 1 with the protrusion 14 formed is used as a mold, and the materials in the prepreg or woven fabric state are laid on both sides of the first component 1. Finally, the materials on both sides of the first component 1 are cured by an autoclave process to form the inner plate 21 and the outer plate 22.

[0072] In some embodiments, the curing process of the materials on both sides of the first component 1 includes, but is not limited to, autoclave, vacuum-assisted resin infusion molding, RTM, or compression molding, etc.

[0073] According to some embodiments of the present invention, the protrusion 14 is provided on the outer surface of the first component 1 by welding, additive manufacturing, or casting. Specifically, the process of preparing the protrusion 14 on the first component 1 can adopt one of welding, additive manufacturing, and casting, or other methods.

[0074] Here, additive manufacturing is also known as 3D printing (3DP), which is a kind of rapid prototyping technology.

[0075] In some embodiments, when the connection component 100 is applied to the triangular window structure of the A-pillar, flanging holes are designed at the upper part of the triangular window structure of the A-pillar. The inner panel 21, the first component 1, and the roof rail reinforcement beam are connected by bolts. The bolts extend in the vehicle height direction and are distributed along the upper part of the triangular window structure of the A-pillar in the vehicle length direction. At the lower part of the triangular window structure of the A-pillar, the inner panel 21 is also connected to the sill by bolts, and the bolts also extend in the vehicle height direction. The outer panel 22 is connected to the sill by adhesive bonding. The dimension of the lower part of the first component 1 in the vehicle width direction can be variably designed by comprehensively considering the vehicle performance requirements and lightweight design, so as to reconcile the two requirements of performance and lightweight.
