[0005] The main body of the reinforcing member includes a first reinforcing member, a second reinforcing member, and a third reinforcing member;
[0006] The first reinforcing member is a long strip-shaped plate structure that extends vertically, and one side of the first reinforcing member is recessed inward, which is suitable for connection with the lower structure of the vehicle body;
[0007] The third reinforcing member is an inclined, elongated, plate-like structure, with the end closest to the second reinforcing member being higher;
[0008] One end of the second reinforcing member is smoothly connected to the upper end of the first reinforcing member, and the other end is connected to the third reinforcing member, so that the main body of the reinforcing member is enclosed to form a triangular layout.
[0009] In one embodiment of the utility model, the angle between the third reinforcing member and the horizontal direction is 30 to 45 degrees.
[0010] In one embodiment of the utility model, the third reinforcing member is provided with a plurality of mounting holes, and the plurality of mounting holes are spaced apart along the length direction of the third reinforcing member, which is suitable for connection with the vehicle body buckle.
[0011] In one embodiment of the utility model, an annular reinforcing rib is further included, which is located on the third reinforcing member and is disposed around the mounting hole, and the annular reinforcing rib protrudes relative to the surface of the third reinforcing member.

[0028] Specific references Figure 1As a triangular reinforced A-pillar of this utility model, the device includes: an integrally formed reinforcing body, the reinforcing body being an inclined plate-like structure, and its overall enclosure forming a triangular layout, suitable for connection between the vehicle body roof and the vehicle rearview mirror; wherein, the reinforcing body includes a first reinforcing member 130, a second reinforcing member 120 and a third reinforcing member 110; the first reinforcing member 130 is a long strip-like plate-like structure extending in the vertical direction, and one side of the first reinforcing member 130 is recessed inward, suitable for connection with the lower structure of the vehicle body; the third reinforcing member 110 is an inclined long strip-like plate-like structure, and the end closer to the second reinforcing member 120 is higher; one end of the second reinforcing member 120 is smoothly connected to the upper end of the first reinforcing member 130, and the other end is connected to the third reinforcing member 110.
[0029] In this example, the angle between the third reinforcing member 110 and the horizontal direction is set to 30 to 45 degrees. The angle design within this range has been optimized through mechanical simulation to ensure that the third reinforcing member 110 forms a reasonable force transmission path when a collision occurs, dispersing the impact force to the first reinforcing member and other structures of the vehicle body. At the same time, it avoids the problem of A-pillar obstruction caused by an excessively large angle or insufficient strength caused by an excessively small angle, thus achieving a balance between safety and practicality.
[0030] In this example, the third reinforcing member 110 has multiple mounting holes 142 for fastening with the vehicle body. These mounting holes 142 are evenly distributed along the length of the third reinforcing member 110 to ensure the balance of the connection between the A-pillar and the vehicle body. Simultaneously, annular reinforcing ribs are provided around the mounting holes 142, and these ribs protrude from the inner surface of the reinforcing member body. The annular reinforcing ribs effectively disperse the stress around the mounting holes, preventing deformation or cracking of the holes due to localized stress concentration caused by the fastening connection, thus enhancing the structural stability of the connection area.
[0031] In this example, the main body of the reinforcing member also has honeycomb-shaped reinforcing ribs, which are evenly distributed. The honeycomb structure, through the mutual support of multiple hexagonal units, can significantly improve the compression and bending resistance of the A-pillar while reducing its overall weight; the evenly distributed design ensures that the reinforcing ribs absorb impact forces uniformly, and the collision energy can be gradually dissipated through the deformation of the honeycomb units during a collision, thereby improving the energy absorption capacity of the A-pillar.
[0032] In this example, the lower end of the third reinforcing member 110 is provided with multiple positioning bosses 141. These positioning bosses 141 cooperate with the mounting positions on the lower part of the vehicle body to achieve precise positioning. The number of positioning bosses is set according to the length of the third reinforcing member and the stress requirements, usually two; and the axis of the positioning bosses 141 is perpendicular to the lower end face of the third reinforcing member, ensuring that the bosses can form a vertical fit with the mounting positions on the vehicle body during installation, avoiding uneven stress on the A-pillar caused by installation deviation, and ensuring assembly accuracy and structural stability.
[0033] In this example, the main body of the reinforcement is made entirely of high-strength alloy steel. This material is characterized by high strength and high toughness, with tensile strength and yield strength superior to traditional steel. It can maintain structural integrity when subjected to large impact forces, reducing the risk of fracture. At the same time, high-strength alloy steel has good fatigue resistance, allowing it to withstand vehicle body vibration and alternating stress during use for extended periods, thus extending the service life of the A-pillar.
[0034] In this example, the thickness of the first reinforcing member 130 adopts a linear gradient design, meaning the thickness gradually increases along its length. Specifically, the thickness is greatest at the lower end of the first reinforcing member, where it connects to the lower structure of the vehicle body, and gradually decreases upwards until it connects to the second reinforcing member. This design conforms to the stress distribution pattern of the first reinforcing member; the lower end, as the main load-bearing part, requires higher thickness for support, while the upper end achieves lightweighting by reducing thickness. This optimizes material usage while ensuring the strength of key parts, achieving weight reduction and efficiency improvement.
[0035] In this example, the concave surface of the first reinforcing member 130 is an arc-shaped structure, and the convex surface is a smooth curved surface, with the edges of the concave and convex surfaces connected by rounded corners. The concave arc-shaped structure can adapt to the spatial layout inside the vehicle body, while the convex smooth curved surface reduces air resistance; the rounded corner design at the edges can effectively eliminate stress concentration at right-angled edges, preventing cracks from forming at the edges during long-term use or collision stress, further improving the structural reliability of the first reinforcing member 130.
[0036] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
