[0053] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0054] In the present utility model, in order to better demonstrate the structure of the A-pillar structure and its connection relationship, the "upper end" referred to in the present utility model is the upper end in the height direction of the vehicle body; the "lower end" referred to in the present utility model is the lower end in the height direction of the vehicle body; the "front end" referred to in the present utility model is the end close to the front of the vehicle in the length direction (also longitudinal) of the vehicle, and the "rear end" referred to in the present utility model is the end close to the rear of the vehicle in the length direction (also longitudinal) of the vehicle.

[0055] like Figures 1 to 3 As shown, an embodiment of the utility model provides an A-pillar structure, including an A-pillar outer reinforcement plate 1, an A-pillar upper reinforcement 2 and an upper longitudinal beam reinforcement plate 4 installed on the front enclosure upper longitudinal beam 3; the A-pillar upper reinforcement 2 includes a first flange 210, a second flange 220 and a first mounting plate 230 for mounting door accessories, the first flange 210 and the second flange 220 are relatively arranged on the front and rear sides of the first mounting plate 230; the first flange 210, the second flange 220 and the first mounting plate 230 are all welded to the A-pillar outer reinforcement plate 1, and the upper longitudinal beam reinforcement plate 4 is connected to the A-pillar outer reinforcement plate 1.

[0056] The A-pillar upper reinforcement 2 is used to install the door upper mounting parts. Specifically, the door upper mounting parts can be door mounting hinges such as scissor-type doors or upper hinges of flat doors. Specifically, the first mounting plate 230 is provided with first mounting holes 240 for installing the door upper mounting parts. The number of the first mounting holes 240 can be set according to the specific structure of the door upper mounting parts to be installed. For example, the number of the first mounting holes 240 can be set to 2, 3, 4, etc. In some embodiments, such as Figure 2 and Figure 3 As shown in FIG. 1 , when the mounting part on the door is a door mounting hinge of a scissor-type door, the first mounting holes 240 can be designed to be four. In this way, the door mounting hinge of the scissor-type door adopts a four-point installation, and the installation area is large, which provides a strong installation strength for the door mounting hinge of the large-sized scissor-type door to prevent the scissor-type door from sinking. Figure 5 and Figure 6 As shown, when the mounted part on the vehicle door is the upper hinge of a casement door, the first mounting hole 240 can be designed to be two. In this way, the upper hinge of the casement door only needs two points of installation to meet the installation requirements, and its installation area is small, which is conducive to the lightweight design of the vehicle.

[0057] Furthermore, a second mounting hole designed opposite to the first mounting hole 240 is provided on the A-pillar outer reinforcement plate 1; in this way, the door assembly is simultaneously installed on the A-pillar outer reinforcement plate 1 and the A-pillar upper reinforcement 2 through the first mounting hole 240 and the second mounting hole, which further improves the fixed connection strength between the A-pillar outer reinforcement plate 1 and the A-pillar upper reinforcement 2, and also further improves the strength and rigidity of the mounting point for installing the door assembly.

[0058] In the present embodiment, the door upper assembly is connected to the first mounting plate 230 of the A-pillar upper reinforcement 2; the first flange 210 and the second flange 220 of the A-pillar upper reinforcement 2 are relatively arranged on the front and rear sides of the first mounting plate 230, the first mounting plate 230, the first flange 210 and the second flange 220 of the A-pillar upper reinforcement 2 are all attached to the A-pillar outer reinforcement plate 1 and are spot welded, and then the A-pillar upper reinforcement 2 is installed on the A-pillar outer reinforcement plate 1, that is, the front and rear surfaces and the bottom surface of the A-pillar upper reinforcement 2 are welded to the A-pillar outer reinforcement plate 1, and the three-sided welding is not easy to fail, which strengthens the strength and rigidity of the mounting point of the door upper assembly, and can also enhance the connection reliability and collision resistance of the A-pillar structure. When the door upper assembly is a door mounting hinge of a scissor-type door, it can also effectively prevent the scissor-type door from sinking during use.

[0059] It is understandable that the specific shape and structure of the A-pillar upper reinforcement 2 can also be set according to needs, for example, it can be set according to the specific type of the door assembly. In one embodiment, when the door assembly is a door installation hinge of a scissor-type door, such as Figure 2 and Figure 3 As shown, the first flange 210 and the second flange 220 of the A-pillar upper reinforcement 2 both extend to the same side of the first mounting plate 230 and form a U-shaped structure with the first mounting plate 230. The upper end of the first mounting plate 230 is also provided with a fixed flange (the fixed flange can also be spot welded on the A-pillar outer reinforcement plate 1) connected between the first flange 210 and the second flange 220, and the lower end of the first mounting plate 230 is designed as an open structure without flanges. In this way, a groove is formed between the first flange 210, the second flange 220, the fixed flange and the first mounting plate 230 of the A-pillar upper reinforcement 2 for accommodating and installing the scissor-type door upper assembly. In another embodiment, as Figure 5 and Figure 6As shown, when the assembly part on the vehicle door is the upper hinge of the casement door, the first flange 210 and the second flange 220 of the A-pillar upper reinforcement 2 both extend to the same side of the first mounting plate 230 and form a U-shaped structure with the first mounting plate 230, but a fixed flange (the fixed flange can also be spot welded on the A-pillar outer reinforcement plate 1) is provided at the upper end of the first mounting plate 230 and connected between the first flange 210 and the second flange 220, and an installation flange (the installation flange can also be spot welded on the A-pillar outer reinforcement plate 1) is provided at the lower end of the first mounting plate 230 and connected between the first flange 210 and the second flange 220. In this way, a groove is formed between the first flange 210, the second flange 220, the fixed flange, the installation flange and the first mounting plate 230 of the A-pillar upper reinforcement 2 for accommodating and installing the upper hinge of the casement door.

[0060] In one embodiment, if Figure 5 and Figure 7 As shown, the A-pillar structure also includes a limiting reinforcement 5, which includes a limiting reinforcement plate 510, a fifth flange 520 arranged on the front side of the limiting reinforcement plate 510, and a sixth flange 530 arranged on the rear side of the limiting reinforcement plate 510; the fifth flange 520, the sixth flange 530 and the limiting reinforcement plate 510 are all welded to the A-pillar outer reinforcement plate 1; the fifth flange 520 is provided with a limiting mounting hole 540 for installing a door limiter. It can be understood that in this embodiment, when the assembly on the door is the upper hinge of a swing-type door, the A-pillar upper reinforcement 2 also includes the above-mentioned limiting reinforcement 5 for installing a door limiter, wherein, in the limiting reinforcement 5, the fifth flange 520 located on the front side of the limiting reinforcement plate 510, the sixth flange 530 located on the rear side of the limiting reinforcement plate 510, and the limiting reinforcement plate 510 are all welded to the A-pillar outer reinforcement plate 1, and the limiting reinforcement plate 510 is located below the A-pillar upper reinforcement 2. In this embodiment, the above-mentioned structure of the limiting reinforcement 5 can not only improve the reliability of the installation point of the door limiter, but also play a role in strengthening the strength of the A-pillar outer reinforcement plate 1 in the longitudinal direction of the vehicle.

[0061] That is, the A-pillar upper reinforcement 2 can be configured differently according to the specific type of the door mounting accessories, and then different door mounting accessories can be installed through the A-pillar upper reinforcement 2 to adapt to scissor-type doors or casement doors. At the same time, when installing different door mounting accessories, the A-pillar structure can also add a limiting reinforcement 5 for the casement door to install a door limiter as needed. In this way, the utility model improves the versatility of the A-pillar structure and saves the development cost and cycle of the A-pillar structure through the above-mentioned different designs for different door types.

[0062] It can be understood that in the present embodiment, the upper longitudinal beam reinforcement plate 4 is installed on the front upper longitudinal beam 3 in the vehicle front panel assembly 12. In this way, in the longitudinal direction of the vehicle, the upper longitudinal beam reinforcement plate 4 is aligned with the front upper longitudinal beam 3 of the vehicle. When the vehicle collides from the front, the collision force is transmitted from the front upper longitudinal beam 3 to the A-pillar outer reinforcement plate 1 and the A-pillar upper reinforcement 2 through the upper longitudinal beam reinforcement plate 4, thereby avoiding significant deformation of the A-pillar structure, reducing the displacement of the door mounting parts (such as the door mounting hinges of the scissor-type doors), and ensuring the smooth opening of the scissor-type doors.

[0063] In the above-mentioned embodiment of the utility model, since the first mounting plate 230 on the A-pillar upper reinforcement 2 for mounting the door mounting accessories and the first flange 210 and the second flange 220 located on the front and rear sides of the first mounting plate 230 are welded to the A-pillar outer reinforcement plate 1, the three-sided welding makes it difficult for the fixed connection between the A-pillar outer reinforcement plate 1 and the A-pillar upper reinforcement 2 to fail, strengthens the strength and rigidity of the mounting point for mounting the door mounting accessories, and can also enhance the connection reliability and collision resistance of the A-pillar structure. When the door mounting accessories are door mounting hinges of a scissor-type door, it can effectively prevent the scissor-type door from sinking during use. At the same time, the upper longitudinal beam reinforcement plate 4 is installed on the front wall upper longitudinal beam 3 and connected to the A-pillar outer reinforcement plate 1. In this way, in the longitudinal direction of the vehicle (that is, the length direction of the vehicle), the A-pillar upper reinforcement 2 is aligned with the front wall upper longitudinal beam 3 of the vehicle. When the vehicle collides from the front, the collision force is transmitted from the front wall upper longitudinal beam 3 to the A-pillar outer reinforcement plate 1 and the A-pillar upper reinforcement 2, thereby avoiding significant deformation of the A-pillar structure, and further avoiding the problem that the scissor-type doors that need to be opened up and down cannot be opened due to the significant deformation of the A-pillar structure.

[0064] In one embodiment, if Figure 1 and Figure 4 As shown, the upper longitudinal beam reinforcement plate 4 is provided with an avoidance groove 410 for avoiding the movement envelope of the door upper mounting part. It can be understood that the door mounting hinge of the scissor-type door needs a large space to rotate during the process of opening and closing the door. In this embodiment, when the door upper mounting part is the door mounting hinge of the scissor-type door, the design of the avoidance groove 410 on the upper longitudinal beam reinforcement plate 4 can avoid the movement envelope of the door mounting hinge of the scissor-type door, and prevent it from interfering with surrounding components in the opening and closing movement state.

[0065] In one embodiment, if Figure 4As shown, the upper longitudinal beam reinforcement plate 4 includes a reinforcement plate 420, a third flange 430 and a fourth flange 440; the third flange 430 is arranged at the rear end of the reinforcement plate 420 and is used to connect the A-pillar outer reinforcement plate 1; the fourth flange 440 is spaced apart from the third flange 430 and is used to connect the front upper longitudinal beam 3. It can be understood that the third flange 430 is arranged at the rear end of the reinforcement plate 420 and is connected to the A-pillar outer reinforcement plate 1, wherein the third flange 430 and the A-pillar outer reinforcement plate 1 can be fixedly connected by spot welding and / or screws. Further, the fourth flange 440 includes an upper flange arranged at the upper end of the reinforcement plate 420 and a lower flange arranged at the lower end of the reinforcement plate 420, that is, Figure 4 The fourth flange 440 shown in the figure has two flanges and is relatively arranged at the upper and lower ends of the reinforcing plate 420, and the upper flange, the lower flange and the reinforcing plate 420 can be spot-welded to the front upper longitudinal beam 3 in the vehicle front panel assembly 12; in this way, through the three-sided welding of the upper flange, the lower flange and the reinforcing plate 420 and the front upper longitudinal beam 3, the upper longitudinal beam reinforcing plate 4 and the front upper longitudinal beam 3 can be firmly connected. In this embodiment, the design of the third flange 430 and the fourth flange 440 and the setting of their connection relationship can enhance the installation strength and rigidity between the A-pillar structure and the front upper longitudinal beam 3. When the vehicle is hit from the front, the front upper longitudinal beam 3 can also decompose the collision force from the front end of the vehicle and disperse the collision force to the A-pillar structure.

[0066] In one embodiment, if Figure 4 and Figure 8 As shown, the A-pillar structure further includes an A-pillar lower reinforcement 6 for installing a lower door assembly and an A-pillar inner reinforcement plate 7 connected to the A-pillar outer reinforcement plate 1. The A-pillar lower reinforcement 6 is installed on the A-pillar outer reinforcement plate 1. An installation cavity is provided between the A-pillar inner reinforcement plate 7 and the A-pillar outer reinforcement plate 1. The A-pillar upper reinforcement 2 and the A-pillar lower reinforcement 6 are both located in the installation cavity and connected to the A-pillar outer reinforcement plate 1. The A-pillar lower reinforcement 6 is used to install a lower door assembly. When the upper door assembly is a door installation hinge of a scissor-type door, the lower door assembly can be a limit block assembly of a scissor-type door; and when the upper door assembly is an upper hinge of a flat-opening door, the lower door assembly can be a lower hinge of a flat-opening door. It can be understood that the A-pillar inner reinforcement plate 7 is installed on the A-pillar outer reinforcement plate 1, and an installation cavity is formed between the A-pillar inner reinforcement plate 7 and the A-pillar outer reinforcement plate 1, and the A-pillar upper reinforcement 2 and the A-pillar lower reinforcement 6 are both located in the installation cavity and connected between the A-pillar outer reinforcement plate 1 and the A-pillar inner reinforcement plate 7. In this way, the A-pillar upper reinforcement 2 and the A-pillar lower reinforcement 6 can not only make the connection structure between the A-pillar outer reinforcement plate 1 and the A-pillar inner reinforcement plate 7 more stable, but also better support the installation cavity, so that the energy absorption performance of the installation cavity is improved when subjected to a side collision.

[0067] In one embodiment, if Figure 4 and Figure 8 As shown, the A-pillar lower reinforcement 6 includes a seventh flange 610, an eighth flange 620, and a second mounting plate 630 for mounting the lower door assembly, wherein the seventh flange 610 is arranged at the front side of the second mounting plate 630; the eighth flange 620 is arranged at the rear side of the second mounting plate 630; the seventh flange 610, the eighth flange 620 and the second mounting plate 630 are all welded to the A-pillar outer reinforcement plate 1. It can be understood that the seventh flange 610 and the eighth flange 620 of the A-pillar lower reinforcement 6 are relatively arranged at the front and rear sides of the second mounting plate 630, and the seventh flange 610, the eighth flange 620 and the second mounting plate 630 are all welded to the A-pillar outer reinforcement plate 1 by spot welding, so that the front and rear surfaces and the bottom surface of the A-pillar lower reinforcement 6 are all welded to the A-pillar outer reinforcement plate 1, and the three-side welding is not easy to fail, which can strengthen the strength and rigidity of the mounting point for mounting the lower door assembly, and also enhance the connection reliability and collision resistance of the A-pillar structure.

[0068] Furthermore, when installing a scissor-type door, a third mounting hole 650 is provided on the second mounting plate 630 of the A-pillar lower reinforcement 6 for installing a lower door assembly; wherein, the A-pillar lower reinforcement 6 is used for installing a lower door assembly, and when the upper door assembly is a door mounting hinge of a scissor-type door, the lower door assembly is a limit block assembly of the scissor-type door, and at this time, the number and position of the third mounting holes 650 can be designed according to the specific structure of the limit block assembly; and when the upper door assembly is an upper hinge of a casement door, the lower door assembly is a lower hinge of the casement door, and at this time, the number and position of the third mounting holes 650 can be designed according to the specific structure of the lower hinge.

[0069] Furthermore, a fourth mounting hole designed to be opposite to the third mounting hole 650 is also provided on the A-pillar outer reinforcement plate 1; thus, the lower door assembly is simultaneously installed on the A-pillar outer reinforcement plate 1 and the A-pillar lower reinforcement 6 through the third mounting hole 650 and the fourth mounting hole, further improving the fixed connection strength between the A-pillar outer reinforcement plate 1 and the A-pillar lower reinforcement 6, and further improving the strength and rigidity of the mounting point for installing the lower door assembly. Furthermore, the side outer panel 11 also includes a fifth mounting hole arranged opposite to the third mounting hole 650 and the fourth mounting hole; thus, the lower door assembly is simultaneously installed on the A-pillar outer reinforcement plate 1, the A-pillar lower reinforcement 6 and the side outer panel 11 through the third mounting hole 650, the fourth mounting hole and the fifth mounting hole, further improving the fixed connection strength between the A-pillar outer reinforcement plate 1, the A-pillar lower reinforcement 6 and the side outer panel 11, and further improving the strength and rigidity of the mounting point for installing the lower door assembly.

[0070] That is, the A-pillar lower reinforcement 6 can also be configured differently according to the specific type of the door upper mounting parts, and then different door lower mounting parts can be installed through the A-pillar lower reinforcement 6 to adapt to scissor-type doors or flat-opening doors. In this way, the utility model improves the versatility of the A-pillar structure and saves the development cost and cycle of the A-pillar structure through the above-mentioned different designs for different door types (the A-pillar upper reinforcement 2 and the A-pillar lower reinforcement 6 need to be adapted to the same type of door at the same time).

[0071] In one embodiment, if Figure 4 and Figure 8 As shown, the A-pillar lower reinforcement 6 also includes a connecting flange 640, which is connected between the seventh flange 610 and the eighth flange 620 and is located on the side of the second mounting plate 630 close to the A-pillar upper reinforcement 2; the A-pillar lower reinforcement 6 is fixedly connected to the A-pillar inner reinforcement plate 7 through the connecting flange 640. It can be understood that the connecting flange 640 is connected to the upper end of the second mounting plate 630, that is, one end installed on the second mounting plate 630 close to the A-pillar upper reinforcement 2. The connecting flange 640 is an L-shaped flange. A plurality of bolt holes are provided on the connecting flange 640. The A-pillar lower reinforcement 6 is located in the mounting cavity, and its end face facing away from the A-pillar inner reinforcement plate 7 is welded to the A-pillar outer reinforcement plate 1. The connecting flange 640 is bolted to the A-pillar inner reinforcement plate 7 by bolts (it can also be welded at the same time), thereby realizing the connection between the A-pillar lower reinforcement 6 and the A-pillar inner reinforcement plate 7. In the event of a collision, the A-pillar structure can be prevented from being torn, and excessive intrusion of the A-pillar structure can be avoided, thereby avoiding an increase in the occupant injury value.

[0072] In one embodiment, if Fig. 9 As shown, the A-pillar structure also includes a front wall cross beam 8 and a front wall lower cross beam 9, the front wall cross beam 8 and the front wall lower cross beam 9 are both welded to the A-pillar outer reinforcement plate 1, and the A-pillar lower reinforcement 6 is bolted to the front wall cross beam 8 and the front wall lower cross beam 9 through the seventh flange 610. It can be understood that when the front wall cross beam 8 and the front wall lower cross beam 9 are welded to the A-pillar outer reinforcement plate 1, the seventh flange 610 of the A-pillar lower reinforcement 6 is connected to the end edge bolts of the front wall cross beam 8 and the front wall lower cross beam 9 by bolts, thereby enhancing the connection stability of the A-pillar outer reinforcement plate 1, the front wall cross beam 8 and the front wall lower cross beam 9; in this way, the A-pillar lower reinforcement 6 is aligned with the front wall cross beam 8 and the front wall lower cross beam 9. When the vehicle has a front collision, the collision force can be transmitted from the front wall lower longitudinal beam (not shown) to the front wall cross beam 8 and the front wall lower cross beam 9, and then the front wall cross beam 8 and the front wall lower cross beam 9 will transmit the force to the A-pillar, which can prevent the A-pillar structure from being significantly deformed, reduce the risk of the A-pillar being detached from the front wall cross beam 8 and the front wall lower cross beam 9 due to collision, reduce the amount of retreat of the A-pillar structure, reduce the displacement of the door hinge, improve the collision safety performance, and ensure that the door can be opened smoothly.

[0073] In one embodiment, if Fig.12 and Fig.13 As shown, the A-pillar structure also includes a sill beam 10 inserted into the installation cavity and connected to the A-pillar outer reinforcement plate 1 and the A-pillar inner reinforcement plate 7; on the side of the second mounting plate 630 away from the A-pillar upper reinforcement 2, the seventh flange 610, the eighth flange 620 and the second mounting plate 630 form a mounting groove, and the sill beam 10 is installed in the mounting groove. It can be understood that the sill beam 10 is inserted into the installation cavity surrounded by the A-pillar inner reinforcement plate 7 and the A-pillar outer reinforcement plate 1. At this time, the end of the A-pillar lower reinforcement 6 away from the A-pillar upper reinforcement 2 is set to an open structure, that is, the seventh flange 610, the eighth flange 620 and the second installation plate 630 of the A-pillar lower reinforcement 6 form an installation groove for installing the sill beam 10. In this way, the design of the installation groove not only avoids the sill beam 10, but also facilitates the stable fixed connection between the sill beam 10 and the A-pillar outer reinforcement plate 1, the A-pillar inner reinforcement plate 7 and the A-pillar lower reinforcement 6. It can be understood that the connection method between the sill beam 10 and the A-pillar outer reinforcement plate 1, the A-pillar inner reinforcement plate 7 and the A-pillar lower reinforcement 6 can be welding or bolt connection.

[0074] In one embodiment, if Figures 12 to 16 As shown, the A-pillar structure further includes a side outer panel 11 , which is connected to a side of the A-pillar outer reinforcement plate 1 away from the A-pillar upper reinforcement 2 , and the sill beam 10 is connected to the side outer panel 11 . It can be understood that the A-pillar upper reinforcement 2 and the A-pillar lower reinforcement 6 are installed on the A-pillar outer reinforcement plate 1, the third flange 430 of the upper longitudinal beam reinforcement plate 4 is arranged at the rear end of the reinforcement plate 420, and the third flange 430 connects the A-pillar outer reinforcement plate 1 and the side panel outer panel 11, and the A-pillar inner reinforcement plate 7 is installed on the A-pillar outer reinforcement plate 1, thereby forming an A-pillar outer panel reinforcement assembly; wherein the side panel outer panel 11 is connected to the side of the A-pillar outer reinforcement plate 1 away from the A-pillar upper reinforcement 2; the A-pillar structure also includes a sill upper reinforcement 13 and a sill reinforcement back plate 14 connected to the sill beam 10, the sill upper reinforcement 13 and the sill reinforcement back plate 14 are respectively arranged on opposite sides of the sill beam 10, the sill beam 10 is installed in the installation groove, the sill reinforcement back plate 14 is connected between the sill beam 10 and the A-pillar outer reinforcement plate 1, and the sill upper reinforcement 13 is connected between the sill beam 10 and the A-pillar inner reinforcement plate 7; further, as Fig.14As shown, the door sill upper reinforcement 13, the A-pillar inner reinforcement plate 7 and the front panel assembly 12 are connected by bolts; the door sill beam 10 and the side panel outer panel 11, the A-pillar outer reinforcement plate 1, the A-pillar lower reinforcement 6, and the door sill reinforcement back plate 14 are connected by bolts, so that the A-pillar outer panel reinforcement assembly, the side panel outer panel 11 and the door sill beam 10 firmly form a side panel assembly. When the vehicle collides, the collision force can be transmitted to the side panel outer panel 11 and the A-pillar structure, thereby improving the collision safety performance.

[0075] Furthermore, the side outer panel 11 also includes a sixth mounting hole arranged opposite to the first mounting hole 240 and the second mounting hole; in this way, the door upper assembly is simultaneously installed on the A-pillar outer reinforcement plate 1, the A-pillar upper reinforcement 2 and the side outer panel 11 through the first mounting hole 240, the second mounting hole and the sixth mounting hole, which further improves the fixed connection strength between the A-pillar outer reinforcement plate 1, the A-pillar upper reinforcement 2 and the side outer panel 11, and also further improves the strength and rigidity of the mounting point for installing the door upper assembly.

[0076] Furthermore, the A-pillar outer panel reinforcement assembly is also connected to the front wheel housing and the front enclosure upper longitudinal beam 3. When the vehicle collides from the front, the collision force is partially dispersed by the front enclosure upper longitudinal beam 3 to the side enclosure outer panel 11 and the door sill beam 10; the A-pillar lower reinforcement 6 extends to the A-pillar inner reinforcement plate 7, and the connection point with the front enclosure cross beam 8 and the front enclosure lower cross beam 9 is arranged at a position that coincides with the wheel, thereby strengthening the connection strength of the A-pillar structure, and can effectively resist wheel impact and prevent cracking in small offset collision conditions.

[0077] In one embodiment, if Fig.12 and Fig.13 As shown, the A-pillar structure further includes a dash panel assembly 12, which is welded to the side of the A-pillar inner reinforcement plate 7 away from the A-pillar outer reinforcement plate 1; and the dash panel assembly 12, the A-pillar inner reinforcement plate 7 and the A-pillar lower reinforcement 6 are connected by bolts. It can be understood that the A-pillar inner reinforcement plate 7 is located between the A-pillar outer reinforcement plate 1 and the dash panel assembly 12. Fig.12 and Fig.13 As shown in the AA section, the connection flange 640 of the A-pillar lower reinforcement 6, the A-pillar inner reinforcement plate 7 and the front panel assembly 12 are connected by bolts to form a three-layer plate connection structure. When the vehicle collides, the A-pillar structure can be prevented from being torn, avoiding excessive intrusion of the A-pillar and greatly reducing the occupant injury value.

[0078] In one embodiment, if Fig.15 and Fig.16As shown in the BB section, the A-pillar lower reinforcement 6, the A-pillar inner reinforcement plate 7 and the front wall cross beam 8 are connected by bolts to form a three-layer plate connection structure. It can be understood that the seventh flange 610 of the A-pillar lower reinforcement 6, the A-pillar inner reinforcement plate 7 and the front wall cross beam 8 are connected by bolts, the connection part of the A-pillar inner reinforcement plate 7 and the front wall assembly 12 can be connected by spot welding, the connection part of the A-pillar lower reinforcement 6 and the front wall cross beam 8 can be connected by spot welding, and the connection part of the A-pillar lower reinforcement 6, the side wall outer panel 11 and the A-pillar inner reinforcement plate 7 can be connected by spot welding. The above connection method can further enhance the stability of the connection between the A-pillar and the front wall cross beam 8, and can also prevent the A-pillar structure from tearing, thereby avoiding excessive intrusion of the A-pillar.

[0079] In one embodiment, if Fig.12 and Fig.14 As shown in the CC section, the A-pillar inner reinforcement plate 7, the front panel assembly 12 and the door sill beam 10 are connected by bolts to form a three-layer plate connection structure, and the side panel outer panel 11, the A-pillar outer reinforcement plate 1, the A-pillar lower reinforcement 6, the door sill beam 10 and the door sill reinforcement back plate 14 are also connected by bolts to form a five-layer plate connection. The door sill beam 10 and the front panel assembly 12 are partially spot-welded at the connection, which enhances the stability of the connection between the A-pillar and the door sill beam 10 and can also prevent the A-pillar structure from tearing, thereby avoiding excessive intrusion of the A-pillar.

[0080] In one embodiment, the A-pillar inner reinforcement plate 7 is an integrally formed structure. It can be understood that the integrally formed A-pillar inner reinforcement plate 7 is installed on the A-pillar outer reinforcement plate 1 to enhance the assembly strength and stability of the A-pillar structure.

[0081] In another embodiment, if Fig.10 and Fig.11 As shown, the A-pillar inner reinforcement plate 7 includes an upper plate 710 and a lower plate 720 connected to the upper plate 710, the upper plate 710 is connected to the A-pillar upper reinforcement 2 and the A-pillar outer reinforcement plate 1, and the lower plate 720 is connected to the A-pillar lower reinforcement 6 and the A-pillar outer reinforcement plate 1. It can be understood that in this embodiment, in order to facilitate manufacturing, the A-pillar inner reinforcement plate 7 can be formed by splicing the upper plate 710 and the lower plate 720 through double-row spot welding. While ensuring manufacturability, the connection of the double-row welding points improves the strength and reduces the deformation caused by collision.

[0082] In one embodiment, the thickness of the upper plate 710 is 1.2 mm to 1.8 mm; the thickness of the lower plate 720 is 1.5 mm to 1.8 mm; the thickness of the lower plate 720 is greater than the thickness of the upper plate 710. It is understandable that the thickness of the upper plate 710 and the thickness of the lower plate 720 can be set according to demand. In this embodiment, both the upper and lower plates 720 can be made of high-strength steel materials. Since the force of the lower plate 720 is greater than that of the upper plate 710, it is necessary to design the thickness of the lower plate 720 to be greater than that of the upper plate 710; the materials of the upper plate 710 and the lower plate 720 can be the same or different. In different cases, the material of the upper plate 710 needs to be slightly softer than that of the lower plate 720, that is, it is necessary to keep the strength of the lower plate 720 greater than that of the upper plate 710, so as to adapt to the force state of the vehicle during actual operation, thereby further reducing the deformation caused by the collision.

[0083] The utility model also provides a vehicle, comprising the above-mentioned A-pillar structure. Figures 17 to 19 As shown, the vehicle door is a scissor-type door; at this time, the vehicle further includes a hinge assembly 15, an electric strut assembly 16, a balance bar assembly 17 and a stop block assembly 18; wherein the hinge assembly 15 includes a door mounting hinge mounted on the A-pillar upper reinforcement 2. The stop block assembly 18 is mounted on the second mounting plate 630 of the A-pillar lower reinforcement 6, and the electric strut assembly 16 is mounted on the side outer panel 11. The electric strut assembly 16 can be extended or shortened under the action of the motor, and the bottom of the electric strut can rotate around the bottom lower connecting shaft pin, and the top of the electric strut can drive the top upper connecting shaft pin, thereby driving the door mounting hinge of the scissor-type door to rotate, thereby driving the scissor-type door to rotate up and down, and at this time, the balance cross bar can rotate to a certain extent around the movable upper connecting shaft pin and the lower connecting shaft pin, thereby cooperating with the rotation of the door mounting hinge to extend or shorten with the opening angle, thereby balancing the gravity of the scissor-type door.

[0084] In the vehicle in the above-mentioned embodiment of the utility model, the A-pillar structure includes an A-pillar outer reinforcement plate 1, an A-pillar upper reinforcement 2 and an upper longitudinal beam reinforcement plate 4 installed on the front enclosure upper longitudinal beam 3; the A-pillar upper reinforcement 2 includes a first flange 210, a second flange 220 and a first mounting plate 230 for mounting door upper accessories, and the first flange 210 and the second flange 220 are relatively arranged on the front and rear sides of the first mounting plate 230; the first flange 210, the second flange 220 and the first mounting plate 230 are all welded to the A-pillar outer reinforcement plate 1, and the upper longitudinal beam reinforcement plate 4 is connected to the A-pillar outer reinforcement plate 1. In the vehicle in the above-mentioned embodiment of the utility model, since the front and rear surfaces and the bottom surface of the A-pillar upper reinforcement 2 are welded to the A-pillar outer reinforcement plate 1, the three-sided welding is not easy to fail, the strength and rigidity of the installation point of the door upper assembly are strengthened, and the connection reliability and collision resistance of the A-pillar structure can also be enhanced. When the door upper assembly is a door installation hinge of a scissor-type door, it effectively prevents the vehicle door from sinking during use; at the same time, the upper longitudinal beam reinforcement plate 4 is installed on the front wall upper longitudinal beam 3 and connected to the A-pillar outer reinforcement plate 1. In this way, in the longitudinal direction of the vehicle (that is, the length direction of the vehicle), the A-pillar upper reinforcement 2 is aligned with the front wall upper longitudinal beam 3 of the vehicle. When the vehicle collides with the front, the collision force is transmitted from the front wall upper longitudinal beam 3 to the A-pillar outer panel reinforcement plate and the A-pillar upper reinforcement 2, thereby avoiding significant deformation of the A-pillar structure, and further avoiding the scissor-type door that needs to be opened up and down from being unable to be opened due to the significant deformation of the A-pillar structure.
