[0035] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0036] Reference below Figure 1-Figure 6 The connector 30 according to the embodiment of the present invention is described. The connector 30 may be applied to an A-pillar connector 100 , and the A-pillar connector 100 may be applied to a vehicle.

[0037] Combination Figure 1-Figure 6 As shown, the connector 30 according to the present invention may mainly include: a first connector 32 and a second connector 33. The first connector 32 is suitable for being fixedly connected to the A-pillar bulging tube 21, and the second connector 33 is suitable for being fixedly connected to the roof front cross beam 10. The connector 30 covers the connection area between the roof front cross beam 10 and the A-pillar bulging tube 21 to improve the connection strength between the roof front cross beam 10 and the A-pillar bulging tube 21.

[0038] Specifically, in order to ensure the normal operation of the A-pillar joint 100 , ensure the structural strength of the A-pillar joint 100 , and ensure the transmission of force between the roof front cross beam 10 and the A-pillar side panel assembly 20 , it is necessary to connect the roof front cross beam 10 to the A-pillar side panel assembly 20 .

[0039] Due to the presence of the A-pillar expansion tube 21, it is difficult to arrange composite reinforcements and other structures in the A-pillar side assembly 20 for reinforcement, and the strength and stiffness requirements of the A-pillar joint 100 cannot be effectively improved. In the vehicle body collision condition, the sheet metal parts in this part may be torn, which is not conducive to the stability of the overall vehicle body structure and cannot meet the vehicle collision safety requirements. At the same time, the strength and stiffness between the roof front cross beam 10 and the A-pillar expansion tube 21 are easily affected by the connection method and connection quality.

[0040] By providing a connector 30, and making the connector 30 include a first connector portion 32 and a second connector portion 33, the connector 30 can be applied to the A-pillar joint, the first connector portion 32 can correspond to and be fixedly connected to the A-pillar bulging tube 21, and the second connector portion 33 can correspond to and be fixedly connected to the roof front cross beam 10, the connector 30 can cover the connection area between the roof front cross beam 10 and the A-pillar bulging tube 21, and the roof front cross beam 10 and the A-pillar bulging tube 21 can be tightly connected together, thereby improving the connection strength between the roof front cross beam 10 and the A-pillar bulging tube 21, and making the A-pillar joint 100 more integrated.

[0041] On the one hand, this can not only make the force transmission between the front cross beam 10 of the roof and the A-pillar expansion tube 21 smoother and transmit the force to various parts of the vehicle body at the same time, but also improve the overall strength and rigidity of the A-pillar joint 100, thereby reducing the bending probability of the A-pillar joint 100 and improving the performance of the A-pillar joint 100 in 25% small offset collision and top pressure conditions, thereby making the passive safety of the A-pillar joint 100 meet relevant requirements, avoiding the living space of the passenger compartment in the vehicle being squeezed and causing casualties in the vehicle, and improving the safety performance of the A-pillar joint 100.

[0042] On the other hand, this can also make the structure of the A-pillar connector 100 simpler, and improve the lightness of the A-pillar connector 100.

[0043] Therefore, by setting the connecting piece 30, the first connecting portion 32 is suitable for being fixedly connected to the A-pillar expansion tube 21, and the second connecting portion 33 is suitable for being fixedly connected to the roof front cross beam 10, and the connecting piece 30 covers the connection area between the roof front cross beam 10 and the A-pillar expansion tube 21, so that the connection strength between the roof front cross beam 10 and the A-pillar expansion tube 21 can be improved, which can not only make the force transmission between the roof front cross beam 10 and the A-pillar expansion tube 21 smoother, but also can improve the overall strength and rigidity of the A-pillar joint 100, thereby improving the safety performance of the A-pillar joint 100.

[0044] Combination Figure 1-Figure 6 As shown, the first connection portion 32 is provided with a first through hole 321 , and the A-pillar expansion tube 21 is provided with a second through hole. The first through hole 321 corresponds to the second through hole and is connected and fixed by a first fastener 50 .

[0045] Specifically, by setting a first perforation 321 on the first connection part 32, setting a second perforation on the A-pillar bulging tube 21, and making the first perforation 321 correspond to the second perforation, it is only necessary to make the first fastener 50 penetrate the first perforation 321 and the second perforation and perform a fastening action, so as to achieve the connection and fixation between the first connection part 32 and the A-pillar bulging tube 21, which can make the connection and fixation between the first connection part 32 and the A-pillar bulging tube 21 simpler and more reliable. Among them, the first fastener 50 includes but is not limited to bolts. And the first connection part and the A-pillar bulging tube are welded separately, so as to avoid the problem of welding point failure, improve the connection stability, and facilitate quality control.

[0046] In some embodiments of the utility model, the second connection part 33 is provided with a third perforation, and the front cross beam 10 of the top cover is provided with a fourth perforation, and the third perforation corresponds to the fourth perforation and is connected and fixed by a second fastener. Specifically, by providing a third perforation on the second connection part 33, providing a fourth perforation on the front cross beam 10 of the top cover, and making the third perforation correspond to the fourth perforation, it is only necessary to make the second fastener penetrate the third perforation and the fourth perforation to correspond and perform a fastening action, so that the connection and fixation between the second connection part 33 and the front cross beam 10 of the top cover can be achieved, and the connection and fixation between the second connection part 33 and the front cross beam 10 of the top cover can be made simpler and more reliable. Among them, the second fastener includes but is not limited to bolts. And the second connection part and the front cross beam of the top cover are welded separately, so that the problem of welding point failure can be avoided, the connection stability can be improved, and the quality control can be facilitated.

[0047] Combination Figure 3-Figure 6 As shown, a boss 31 is provided on the connecting member 30, and the boss 31 is provided between the first connecting portion 32 and the second connecting portion 33. A fifth through hole 311 is provided on the boss 31, and the fifth through hole 311 corresponds to the sixth through hole on the A-pillar reinforcement plate 23 and is connected and fixed by a third fastener.

[0048] In this way, the connection and fixation between the connecting piece 30 and the A-pillar reinforcement plate 23 can be achieved through the third fastener, which can make the connection and fixation between the connecting piece 30 and the A-pillar reinforcement plate simpler and more reliable, thereby improving the overall structural strength and structural reliability of the A-pillar joint 100, and enhancing the force transmission performance and safety performance of the A-pillar joint 100.

[0049] Furthermore, through the design of the boss 31, the structural strength near the fifth through-hole 311 can be improved, the elastic deformation at the fifth through-hole 311 can be reduced, and the stress can be dispersed in time, thereby improving the structural strength of the connection point between the connector 30 and the A-pillar reinforcement plate 23 and improving the overall structural reliability of the vehicle body.

[0050] Furthermore, combined with Figure 3-Figure 6As shown, the boss 31 is provided with a reinforcing rib 312 on the circumferential outer side, and there are multiple reinforcing ribs 312, and the multiple reinforcing ribs 312 are staggered in a cross shape. Such a configuration can further improve the reliability and stability of the structure near the fifth through hole 311, further reduce the elastic deformation at the fifth through hole 311, and further ensure that the stress can be dispersed in time, thereby further improving the strength and rigidity of the structure near the fifth through hole 311, and further improving the structural strength of the connection point between the connecting plate body and the A-pillar reinforcement plate 23. It should be noted that, under the condition of ensuring rigidity and strength, the width of the reinforcing rib 312 can be appropriately reduced to avoid the problem of weight increase caused by the reinforcing rib 312 being too large and too dense.

[0051] Combination Figure 1-Figure 6 As shown, the connecting member 30 may also include a third connecting portion 34, the first connecting portion 32 is connected to the first tube segment 211 of the A-pillar expansion tube 21, the third connecting portion 34 is connected to the second tube segment 212 of the A-pillar expansion tube 21, the first tube segment 211 and the second tube segment 212 both extend in the front-to-rear direction of the vehicle, and the first tube segment 211 and the second tube segment 212 are spaced apart in the front-to-rear direction of the vehicle.

[0052] Specifically, when the connecting member 30 only includes the first connecting portion 32 and the second connecting portion 33, it can be adapted to a convertible vehicle. However, when the vehicle is not a convertible vehicle, the front cross beam 10 of the roof needs to be connected to the middle position of the A-pillar expansion tube 21. The first connecting portion 32 and the second connecting portion 33 cannot completely cover the connection area between the front cross beam 10 of the roof and the A-pillar expansion tube 21, and cannot stably improve the force transmission performance of the non-convertible vehicle.

[0053] When the vehicle is not a convertible, the A-pillar expansion tube 21 can be segmented at the front cross beam 10 of the roof, so that the A-pillar expansion tube 21 includes a first tube segment 211 and a second tube segment 212 spaced apart in the front and rear, and the connecting member 30 also includes a third connecting portion 34. In this way, the third connecting portion 34 can be adapted to the setting position of the second tube segment 212 and connected to the second tube segment 212 on the premise that the first through hole 321 on the first connecting portion 32 corresponds to the second through hole on the first tube segment 211 and is connected and fixed by the first fastener 50, and the third through hole on the second connecting portion 33 corresponds to the fourth through hole on the front cross beam 10 of the roof and is connected and fixed by the second fastener.

[0054] In this way, the structural design of the connector 30 can be optimized, the connection and fixation between the connector 30 and the first pipe section 211, the second pipe section 212 and the front cross beam 10 of the roof can be facilitated, and the connector 30 can be adapted to the design of non-convertible vehicles.

[0055] Furthermore, combined with Figure 1-Figure 6As shown, the third connection part 34 is provided with a seventh through-hole 331, and the second pipe section 212 is provided with an eighth through-hole, and the seventh through-hole 331 corresponds to the eighth through-hole and is connected and fixed by the fourth fastener 60. Specifically, by providing the seventh through-hole 331 on the third connection part 34, providing the eighth through-hole on the second pipe section 212, and making the seventh through-hole 331 correspond to the eighth through-hole, it is only necessary to make the fourth fastener 60 penetrate the seventh through-hole 331 and the eighth through-hole correspond to each other and perform a fastening action, so as to realize the connection and fixation between the third connection part 34 and the second pipe section 212, and make the connection and fixation between the third connection part 34 and the second pipe section 212 simpler and more reliable. Among them, the fourth fastener 60 includes but is not limited to bolts. And the third connection part and the second pipe section are welded separately, so as to avoid the problem of welding point failure, improve the connection stability, and facilitate quality control.

[0056] It should be noted that, considering that the first pipe section 211 can meet the requirements of stiffness and top pressure performance, when the A-pillar joint 100 is a convertible, the second pipe section 212 can be cancelled, and when the A-pillar joint 100 is a non-convertible, the first pipe section 211 and the second pipe section 212 are both retained, that is, the convertible and the non-convertible can share the first pipe section 211, which not only improves the commonality rate of parts, but also the first pipe section 211 can share a set of molds during production, which can reduce production costs.

[0057] In some embodiments of the present invention, the connecting member 30 is an integrally manufactured structural member.

[0058] Specifically, the connector 30 can be configured as an integrally manufactured structural component, which can not only simplify the production process of the connector 30 and improve the production efficiency of the connector 30, but also improve the structural strength and structural reliability of the connector 30, thereby improving the force transmission performance and anti-top pressure performance of the A-pillar joint 100 and even the vehicle.

[0059] Optionally, the connector 30 can be configured as a structural component made of one piece of cast aluminum. The structural strength of the cast aluminum component is much higher than that of the sheet metal connection, which can not only further enhance the structural strength and structural reliability of the connector 30, but also eliminate the need to set up reinforcing plates and other components for reinforcement, thereby meeting lightweight design requirements.

[0060] In addition, unlike setting the connecting part as a sheet metal part, by setting the connecting part 30 as a structural part made of cast aluminum, in the top pressure condition, the top pressure of the A-pillar joint 100 is directly transmitted from the top of the side wall to the connecting part 30, and then transmitted from the connecting part 30 to the front cross beam 10 of the roof, which can simplify the force transmission path and further improve the force transmission performance and top pressure resistance performance of the A-pillar joint 100.

[0061] It should be noted that the connecting member 30 includes but is not limited to a structural member made of cast aluminum, which will not be described in detail here.

[0062] Combination Figure 1 and Figure 2 As shown, the first connection portion 32 at least partially overlaps with the first pipe segment 211, and the overlapping length of the first connection portion 32 and the first pipe segment 211 is L1. The third connection portion 34 at least partially overlaps with the second pipe segment 212, and the overlapping length of the third connection portion 34 and the second pipe segment 212 is L2. L1 and L2 satisfy the relationship: L1≥130mm, L2≥100mm.

[0063] Such a configuration can not only facilitate the opening of the first through hole 321, the second through hole, the third through hole, the fourth through hole, the seventh through hole 331 and the eighth through hole, but also facilitate the connection between the first connecting portion 32 and the first pipe segment 211, and the connection between the third connecting portion 34 and the second pipe segment 212, and can further improve the connection reliability between the first connecting portion 32 and the first pipe segment 211, and the connection reliability between the third connecting portion 34 and the second pipe segment 212, thereby further improving the overall structural reliability of the A-pillar connector 100.

[0064] In some embodiments of the present invention, the thickness of the first pipe segment 211 is T1, the thickness of the second pipe segment 212 is T2, and T1 and T2 satisfy the relationship: T1>T2. Wherein, the first pipe segment 211 and the second pipe segment 212 are both hollow pipe segments, the thickness of the first pipe segment 211 refers to the wall thickness of the first pipe segment 211, and the thickness of the second pipe segment 212 refers to the wall thickness of the second pipe segment 212.

[0065] Specifically, in the static pressure and frontal collision conditions of the top cover of the A-pillar joint 100, due to the need for occupant protection, the force on the A-pillar side assembly 20 is mainly concentrated in the front half, and the rear half is less stressed. The first tube section 211 of the A-pillar expansion tube 21 is located on the front side, and the second tube section 212 of the A-pillar expansion tube 21 is located on the rear side. By setting the thickness of the first tube section 211 to be greater than the thickness of the second tube section 212, the first tube section 211 and the second tube section 212 can be more fully utilized, while meeting the requirements of strength and stiffness, etc., and more in line with the requirements of lightweight design, which can reduce material loss. It should be noted that in actual production, the specific thickness of the first tube section 211 and the second tube section 212 can be flexibly adjusted according to actual needs, and no specific limitation is made here.

[0066] Combination Figure 1 and Figure 2As shown, the A-pillar joint 100 according to the embodiment of the utility model may mainly include: a roof front cross beam 10, an A-pillar side assembly 20 and the above-mentioned connector 30, wherein the A-pillar side assembly 20 includes an A-pillar bulging tube 21. In this way, the connector 30 may cover the connection area between the roof front cross beam 10 and the A-pillar bulging tube 21, thereby improving the connection strength between the roof front cross beam 10 and the A-pillar bulging tube 21, tightly connecting the roof front cross beam 10 and the A-pillar bulging tube 21 together, and improving the force transmission performance and safety performance of the A-pillar joint 100.

[0067] Furthermore, the connector 30 may also include: a third connection portion 34. Specifically, when the vehicle is a non-convertible vehicle, the front cross beam 10 of the roof needs to be connected to the middle position of the A-pillar bulging tube 21, and the first connection portion 32 and the second connection portion 33 cannot completely cover the connection area between the front cross beam 10 of the roof and the A-pillar bulging tube 21, and the force transmission performance of the non-convertible vehicle cannot be stably improved. By making the connector 30 also include: a third connection portion 34, the third connection portion 34 can also be connected to the A-pillar bulging tube 21, so that the connector 30 can completely cover the connection area between the front cross beam 10 of the roof and the A-pillar bulging tube 21, so that the connector 30 can adapt to the design of non-convertible vehicles and improve the safety performance of non-convertible vehicles.

[0068] Combination Figure 1 and Figure 2 As shown, the A-pillar side panel assembly 20 may further include an A-pillar inner panel 22 , which is connected to the A-pillar expansion tube 21 and includes a first panel segment 221 and a second panel segment 222 , wherein the first panel segment 221 is connected to the first connection portion 32 , and the second panel segment 222 is connected to the third connection portion 34 .

[0069] Specifically, the A-pillar inner panel 22 is connected to the A-pillar expansion tube 21 to form the basic structure of the A-pillar side panel assembly 20 to ensure the structural strength of the A-pillar side panel assembly 20. The A-pillar inner panel 22 is also segmented at the position of the front cross beam 10 of the roof, so that the A-pillar inner panel 22 is divided into a first panel segment 221 and a second panel segment 222 arranged at a front and rear interval. The first panel segment 221 and the first tube segment 211 are connected correspondingly, and the second panel segment 222 and the second tube segment 212 are connected correspondingly. The first panel segment 221 is connected to the first connecting portion 32, and the second panel segment 222 is connected to the third connecting portion 34. Therefore, the A-pillar side panel assembly 20 and the connecting member 30 can be connected as a whole, which can further improve the structural reliability of the A-pillar joint 100.

[0070] It should be noted that the first plate segment 221 and the first connection portion 32 can be connected by bolts, rivets, etc., and the second plate segment 222 and the third connection portion 34 can be connected by bolts, rivets, etc., which are not specifically limited here. In addition, the first plate segment and the first connection portion are welded separately, and the second plate segment and the third connection portion are welded separately, so as to avoid the problem of welding point failure, improve the connection stability, and facilitate quality control.

[0071] In addition, by making the A-pillar inner panel 22 include the first panel segment 221 and the second panel segment 222, when the A-pillar joint 100 is a convertible, the second panel segment 222 can be cancelled, and when the A-pillar joint 100 is a non-convertible, the first panel segment 221 and the second panel segment 222 are both retained, that is, the convertible and the non-convertible can share the first panel segment 221, thereby not only improving the commonality rate of parts, but also the first panel segment 221 can share a set of molds during production, thereby reducing production costs.

[0072] Combination Figure 1 As shown, the A-pillar side panel assembly 20 may further include: an A-pillar reinforcement plate 23 , the A-pillar reinforcement plate 23 is extended in the front-rear direction of the vehicle, the A-pillar expansion tube 21 is connected between the A-pillar inner panel 22 and the A-pillar reinforcement plate 23 , and the A-pillar reinforcement plate 23 is connected to the connecting piece 30 .

[0073] Specifically, the A-pillar reinforcement plate 23 is extended in the front-rear direction of the vehicle, and the structural strength of the A-pillar side panel assembly 20 can be enhanced by connecting the A-pillar expansion tube 21 between the A-pillar inner panel 22 and the A-pillar reinforcement plate 23. In addition, by connecting the A-pillar reinforcement plate 23 with the connecting member 30, on the one hand, the A-pillar reinforcement plate 23 can play a certain structural reinforcement role on the connecting member 30, and can improve the structural strength and structural rigidity of the connecting member 30. On the other hand, the connecting member 30 and the A-pillar side panel assembly 20 can form a more stable whole, thereby further improving the stability of the vehicle body structure and meeting the collision safety requirements of the A-pillar joint 100.
