DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0021] Referring to Figures 1 to 3 as shown, an embodiment of the present invention provides a connection structure between an upper mounting plate and an A-pillar, including an upper mounting plate 1, an upper mounting plate reinforcement plate 2, and an A-pillar, wherein:
[0022] There are two A-pillars, and the two A-pillars are respectively located on opposite sides of the length direction of the upper mounting plate 1. The opposite ends of the length direction of the upper mounting plate 1 are respectively connected to the two A-pillars. The A-pillars on the left and right sides of the vehicle are connected through the upper mounting plate 1 to achieve left-right penetration. The A-pillar can absorb the impact force transmitted from the front cabin of the vehicle through the upper mounting plate 1, enabling the vehicle to effectively resist the frontal impact of the vehicle and ensuring the safety performance of the vehicle.
[0023] The opposite ends of the width direction of the upper mounting plate 1 are respectively connected to the opposite ends of the width direction of the upper mounting plate reinforcement plate 2. The upper mounting plate 1 and the upper mounting plate reinforcement plate 2 enclose a cavity, and the cross-section of the cavity is a trapezoid-like structure. Utilizing the advantages of high structural strength and good stability of the cavity structure, the damage and deformation of the upper mounting plate 1 when subjected to collision impact force are effectively reduced, the structural strength of the A-ring area is increased, which helps to improve the modal of the front windshield, solve the vibration problem caused by the transfer of road excitation load to the front windshield, and improve the NVH performance and the overall vehicle use quality.
[0024] Referring to Figure 3 as shown, the A-pillar includes a front side plate 3 and an A-pillar reinforcement plate 4. The opposite ends of the width direction of the A-pillar reinforcement plate 4 are respectively connected to the plate body of the front side plate 3. The A-pillar reinforcement plate 4 and the front side plate 3 enclose a cavity. The cross-section of the cavity is a flat box-like structure, which can strengthen the structural strength between the front side plate 3 and the A-pillar reinforcement plate 4. When the vehicle undergoes a frontal collision and an offset collision, the A-pillar reinforcement plate 4 receives the impact force transmitted from the front cabin of the vehicle, and can be absorbed through the side wall of the A-pillar reinforcement plate 4 and the front side plate 3, improving the vehicle collision performance and thus improving the vehicle safety.
[0025] Furthermore, continue to refer to Figure 3As shown, the end of the upper mounting plate 1 is connected to the front side plate 3. The connection point between the upper mounting plate 1 and the front side plate 3 is close to the middle of the front side plate 3. In the embodiment provided by the present utility model, the dimensions of both ends of the upper mounting plate 1 are widened. The upper mounting plate 1 and the upper mounting plate reinforcing plate 2 extend up to near the middle area of the cavity formed by the front side plate 3 and the A-pillar reinforcing plate 4, so that both ends of the upper mounting plate 1 can be connected to the front side plate 3 and the A-pillar reinforcing plate 4 simultaneously, increasing the connection area of the upper mounting plate 1. When the vehicle is subjected to an offset collision, the upper mounting plate 1 can conduct the impact force to the A-pillar cavity area. This impact force can be resisted and absorbed by using the high structural strength of the cavity, and it is convenient to utilize the stable load-bearing property of the cavity to resist the external force pulling and deformation, improving the vehicle collision performance and thus enhancing the vehicle safety.
[0026] In a feasible implementation manner, referring to Figure 3 As shown, the upper mounting plate 1 includes a main body portion 11 and a bending portion 12. A preset angle is formed between the extending direction of the bending portion 12 and that of the main body portion 11. The bending portion 12 is in fit connection with the front side plate 3. By fitting the bending portion 12 with the front side plate 3, the contact area during connection is increased, providing a basis for subsequent bonding or welding, thereby ensuring the firm connection between the upper mounting plate 1 and the A-pillar. The angle of the preset angle formed between the bending portion and the main body portion 11 can be determined according to actual needs and is not limited herein. The extending direction of the main body portion 11 is inclined to the advancing direction of the vehicle. In this way, whether the vehicle is subjected to a frontal collision or an offset collision, the impact force can be effectively conducted on the main body portion 11. The main body portion 11 can decompose the impact force into a component force along the advancing direction of the vehicle and a component force perpendicular to the advancing direction of the vehicle. Both of these two component forces can be effectively absorbed by the vehicle body, effectively reducing the damage and deformation of the upper mounting plate 1 when it is subjected to a collision impact force.
[0027] The upper mounting plate 1 is connected to the front side plate 3 by bonding or welding. By the bonding connection method, the upper mounting plate 1 and the front side plate 3 are sealed with coating glue, which can effectively reduce the risk of water leakage and sealing in this area. While by the welding connection method, it can better ensure the structural rigidity and structural integrity of the connection between the upper mounting plate 1 and the front side plate 3, ensuring its structural strength. At the same time, the fit connection between the bending portion 12 of the upper mounting plate 1 and the front side plate 3 realizes a horizontal welding surface, facilitating the welding operation and further improving the structural strength.
[0028] In the embodiment provided by the present utility model, referring to Figure 3As shown, on the side of the A-pillar reinforcement plate 4 facing away from the front side panel 3, there is a connection with the outer side panel 5 of the side wall. A cavity is formed between the outer side panel 5 of the side wall and the A-pillar reinforcement plate 4. The outer side panel 5 of the side wall and the A-pillar reinforcement plate 4 are welded and fixed. The cavity is in a flat shape. By utilizing the advantages of the cavity structure with high strength and good stability, the strength of the outer side panel 5 of the side wall is greatly improved. When the outer side panel 5 is subjected to an impact force, the external force can be effectively transmitted to the A-pillar reinforcement plate 4 and then respectively transmitted to other parts of the vehicle body, decomposing the force on the outer side panel 5 of the side wall. Thus, the local stiffness and dent resistance of the outer side panel 5 of the side wall are effectively improved, and the appearance damage such as dents generated when the outer side panel 5 is stressed is effectively reduced. At the same time, its anti-collision performance is enhanced.
[0029] Furthermore, reinforcing ribs are provided on the plate surface of the upper mounting plate 1. The reinforcing ribs extend from both ends of the plate surface of the upper mounting plate 1 towards the middle of the plate surface. By setting the reinforcing ribs, the overall structural strength and stiffness are improved. Preferably, the reinforcing ribs are in an "L" shape structure.
[0030] In the embodiments provided by the present application, with reference to Figure 2 As shown, at one end of the upper mounting plate 1 in the width direction, there is a connection with the lower mounting plate 6. On the side of the lower mounting plate 6 facing away from the upper mounting plate 1, there is a connection with a lower mounting plate reinforcement plate 7 and a front partition plate 8. A cavity is formed between the lower mounting plate reinforcement plate 7 and the lower mounting plate 6. By utilizing the advantages of the cavity structure with high strength and good stability, the damage and deformation suffered by the lower mounting plate 6 when subjected to a collision impact force are effectively reduced, and the structural strength of the A-ring area is increased.
[0031] In addition, the embodiments of the present invention also provide a vehicle, including the connection structure between the upper mounting plate and the A-pillar described above. Among them, the body structure of this vehicle is the prior art. Therefore, the specific body structure of the vehicle in this embodiment will not be elaborated further.
[0032] The connection structure between the upper mounting plate and the A-pillar provided by the embodiments of the present invention has the aforementioned technical effects. Therefore, a vehicle having this connection structure between the upper mounting plate and the A-pillar should also have the corresponding technical effects.
[0033] The connection structure between the upper mounting plate and the A-pillar and the vehicle provided by the embodiments of the present invention strengthen the connection of the A-pillars on both left and right sides through the upper mounting plate 1 and the upper mounting plate reinforcement plate 2, making the lower mounting surface of the front windshield more stable, thereby improving the mode of the front windshield and solving the NVH vibration problem.
