A reinforcing beam for a tunnel in a front floor of an automobile

Abstract

This utility model discloses a reinforcing beam for a passageway in the front floor of an automobile, comprising a passageway plate and reinforcing beams. Three sets of reinforcing beams are fixedly welded to the bottom surface of the passageway plate, with transverse ribs welded between adjacent sets of reinforcing beams. Side ribs are fixedly welded to the outer side of the reinforcing beams and the passageway plate. The main body of each side rib is an oblique L-shaped rib plate, and a second branch rib in contact with the bottom surface of the passageway plate is fixedly welded to the center of the bottom side of the side rib. The transverse ribs are T-shaped rib plates, with two sets of opposing first branches fixedly welded to the bottom side of the transverse ribs, and the transverse ribs are also fixedly welded to the bottom surface of the passageway plate via the first branches. This reinforcing beam for a passageway in the front floor of an automobile, through the setting of the reinforcing beams on the bottom side of the passageway plate and the transverse and side ribs on its outer side, can increase its weight by utilizing the reinforcing beams. Simultaneously, each set of transverse and side ribs can increase its contact points and contact area with the bottom surface of the passageway plate, thereby maximizing its own pressure-bearing effect.

Description

Technical Field

[0001] This utility model relates to the field of automotive channel floor technology, specifically a reinforcing beam for the central channel of the front floor of an automobile. Background Technology

[0002] The center tunnel in the front floor of a car serves as a structural reinforcement through its U-shaped structure. However, many surrounding body parts are directly welded or screwed onto the center tunnel, increasing its load and failing to meet basic safety and comfort requirements. This poses potential safety hazards and negatively impacts the normal operation of the vehicle.

[0003] A search revealed that patent application CN201721363035.7 discloses a reinforcing beam for the center tunnel of a car's front floor. The structure includes a center tunnel body assembly, a rear reinforcing beam, a front reinforcing beam, a center tunnel cover assembly, and a tire pressure monitoring system mounted on a bracket. All four components—the rear, front, and cover beams—are mounted on the surface of the center tunnel body assembly. While this application increases the compressive strength by using two sets of reinforcing beams, the limited contact points and area between a single beam and the tunnel floor limit the load-bearing capacity.

[0004] Therefore, we propose a reinforcing beam for the central channel in the front floor of a car. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a reinforcing beam for the central channel of the front floor of an automobile, which solves the problem that the limited contact points and area between the single beam and the channel floor plate in existing devices result in limited pressure-bearing capacity.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a reinforcing beam for a passageway in the front floor of an automobile, comprising a passageway plate and reinforcing rib beams on its bottom side, wherein three sets of reinforcing rib beams are fixedly welded to the bottom surface of the passageway plate, and transverse ribs are welded between adjacent sets of reinforcing rib beams, and side ribs are fixedly welded between the outer side of the reinforcing rib beams and the passageway plate.

[0007] The main body of the side reinforcement is an inclined L-shaped reinforcement plate, and a second support reinforcement that contacts the bottom surface of the channel plate is fixedly welded at the center of the bottom side of the side reinforcement.

[0008] The transverse rib is a T-shaped rib plate. Two sets of first supporting ribs in opposite positions are fixedly welded to the bottom side of the transverse rib, and the transverse rib is also fixedly welded to the bottom surface of the channel plate through the first supporting ribs.

[0009] Preferably, the top edge of the reinforcing beam is a first welded part in the shape of an arc, and the top edges of the side ribs and transverse ribs are third welded parts and second welded parts that are adapted to the specifications of the top edge of the reinforcing beam.

[0010] Preferably, the inclination angle of the second branch bar on the bottom side of the side bar is 45 degrees, and the angle between the second branch bar and the bottom surface of the side bar is a rounded corner.

[0011] Preferably, two sets of first support bars with opposite positions and an inclination of 45 degrees are fixedly installed on the bottom side of the transverse bar, and the angle between the first support bars and the bottom surface of the transverse bar is a rounded corner.

[0012] Preferably, the top side of the transverse rib is an arc-shaped surface, and the top edge of the side rib is also an arc-shaped surface.

[0013] Preferably, the transverse and side ribs are made of steel and doped with chromium, molybdenum and titanium.

[0014] This invention provides a reinforcing beam for the central tunnel in the front floor of an automobile. It has the following beneficial effects:

[0015] This reinforcing beam for the passageway in the front floor of a car increases its weight by setting reinforcing beams on the bottom side of the passageway plate and horizontal and side ribs on its outer side. At the same time, each set of horizontal and side ribs increases the contact points and contact area with the bottom surface of the passageway plate, thereby maximizing its own pressure-bearing effect and ensuring pressure-bearing capacity. This solves the problem that the existing device has limited contact points and area between a single beam and the bottom plate of the passageway, resulting in limited pressure-bearing effect.

Three sets of reinforcing rib beams 2 are fixedly welded to the bottom surface of the passageway plate 1. A transverse rib 3 is welded between two adjacent sets of reinforcing rib beams 2, and a side rib 4 is fixedly welded between the outer side of the reinforcing rib beam 2 and the passageway plate 1.

[0023] The main body of the side reinforcement 4 is an oblique L-shaped reinforcement plate, and a second support reinforcement 41 that contacts the bottom surface of the channel plate 1 is fixedly welded at the center of the bottom side of the side reinforcement 4.

[0024] The transverse rib 3 is a T-shaped rib plate. Two sets of first support ribs 31 with opposite positions are fixedly welded to the bottom side of the transverse rib 3, and the transverse rib 3 is also fixedly welded to the bottom surface of the channel plate 1 through the first support ribs 31.

[0025] In this embodiment, it should be further explained that the reinforcing beam for the passageway in the front floor of the car, through the setting of the reinforcing beam 2 on the bottom side of the passageway plate 1 and its outer transverse ribs 3 and side ribs 4, can increase its weight by using the reinforcing beam 2. At the same time, each set of transverse ribs 3 and side ribs 4 can increase its contact points and contact area with the bottom surface of the passageway plate 1, thereby maximizing its own pressure-bearing effect and ensuring pressure-bearing capacity. This solves the problem that the existing device has limited contact points and areas between a single beam and the bottom plate of the passageway, resulting in limited pressure-bearing effect.

[0026] In this embodiment, it should be further explained that the top edge of the reinforcing beam 2 is a first welded part 21 in the shape of an arc, and the top edges of the side ribs 4 and the transverse ribs 3 are a third welded part 42 and a second welded part 32 that are adapted to the specifications of the top edge of the reinforcing beam 2.

[0027] In this embodiment, it should be noted that the inclination angle of the second branch rib 41 on the bottom side of the side rib 4 is forty-five degrees, and the angle between the second branch rib 41 and the bottom surface of the side rib 4 is a rounded corner.

[0028] In this embodiment, it should be noted that two sets of first support bars 31 with opposite positions and an inclination of 45 degrees are fixedly installed on the bottom side of the transverse bar 3, and the angle between the first support bar 31 and the bottom surface of the transverse bar 3 is a rounded corner.

[0029] In this embodiment, it should be noted that the top side of the transverse rib 3 is an arc-shaped surface, and the top edge of the side rib 4 is also an arc-shaped surface.

[0030] In this embodiment, it should be noted that the transverse rib 3 and the side rib 4 are both made of steel and doped with chromium, molybdenum and titanium.

[0031] The working principle and usage process of this utility model are as follows: When the device is required to work, the reinforcing beam 2 and each group of transverse ribs 3 and side ribs 4 are fixedly welded to the bottom surface of the channel plate 1 to increase the contact points and contact area between them and the bottom surface of the channel plate 1, so as to evenly distribute the pressure received by the channel plate 1 and ensure the pressure bearing effect.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
