Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention has a side door installed inside the door to absorb the impact force from the side of the car. This invention relates to a side door beam structure in which a beam is arranged in the vehicle length direction.

0002

[Conventional technology]

In general, there are many accidents where cars collide from the side at intersections, so the door area Some kind of safety measures are required, and conventionally, side door beams have been installed inside the door. There is a lot going on.

0003 For example, as shown in FIGS. 4(a) and 4(b), a sheet metal is placed inside the door 2 of the automobile 1. A side door beam (impact bar) 3 that is bent to form an uneven shape is installed in a car. It is arranged in the longitudinal direction. In addition, in FIG. 4(a), 4 is the latch of the door 2, and 5 is the latch of the door 2. This is a hinge that pivotally supports the door 2 on the vehicle body side of the automobile 1.

0004 With the above configuration, the car 1 is hit from the side and receives a large impact force. Due to the deformation of the side door beam 3, which is installed inside the door 2 and has sufficient strength, The impact force is absorbed and damage to the occupants inside the car 1 is reliably prevented. This improves safety in the event of a collision.

[0005] There is also a pipe-shaped side door beam, but it is not enough. In order to obtain a high yield strength, it is necessary to increase the diameter of the pipe. There is a door inside door 2. In addition to storing other parts such as Agulhas, there are also restrictions on the thickness of the door 2 itself. The side door beam alone cannot occupy the space inside door 2. Therefore , it is possible to obtain sufficient strength while effectively using the space inside the door 2, Fig. Use a side door beam 4 having an uneven shape as shown in 5(a) and (b). are increasing.

[0006]

[Problem that the idea aims to solve]

Even with such a conventional side door beam structure, impact force from the side of the car 1 can be reduced. However, it is possible to obtain a larger resistance force to reduce safety in the event of a collision. It is hoped that this will be further increased.

[0007] In addition, in the conventional side door beam structure, the impact input to the side door beam 3 Since the force is transmitted to the vehicle body through the latch 4 and hinge 5 of the door 2, It is necessary to significantly strengthen the latch 4 and hinge 5 attachment areas and their surrounding areas. .

[0008] The present invention was devised in view of these issues, and uses a simple reinforcement structure to improve side Ensures that the impact force received by the door beam is transmitted to the vehicle body to ensure sufficient strength. To provide a wire-type side door beam structure that ensures safety in the event of a collision. With the goal.

[0009]

[Means to solve the problem]

For this reason, the wire-type side door beam structure of this invention is designed to prevent A side door beam is placed inside the vehicle door in the longitudinal direction of the vehicle to absorb impact force. In the side door beam structure made of and lock one end of the wire near the door open side end of the side door beam. At the same time, extend the other end of the wire from the door shaft support side end of the side door beam. It is characterized by passing near the pivot portion of the door and being secured to the vehicle body side of the vehicle. Ru.

[Effect]

The wire type side door beam structure of the present invention described above prevents impact from the side of the vehicle. When the side door beam deforms due to impact force and its displacement increases, this side door Tension is generated in the wires running along the beam, which increases the impact on the side door beam. The impact force is transmitted to the vehicle body through the wire.

[0011]

【Example】

The drawings below show a wire type side door beam structure as an embodiment of the present invention. 1 is a side view, FIG. 2 is an enlarged sectional view taken along line II-II of FIG. 1, and FIG. is a cross section showing the state in which this structure is deformed due to impact force with respect to the III-III cross section in Figure 1. It is a diagram.

0012 As shown in FIGS. 1 to 3, in this embodiment as well, the driver of the automobile 1 is Inside A2, there is a side door beam (interior) made by bending sheet metal to form an uneven shape. pact bar) 3 from the end of the door shaft support side (hinge 5 side) to the door opening side (latch 4 side). ) are arranged in the longitudinal direction of the vehicle up to the end.

[0013] Further, the door 2 is pivotally supported on the vehicle body side via a hinge (spindle support) 5, and A latch 4 for locking the door 2 is provided on the open end side of the door 2. .

[0014] In this embodiment, the wire 6 is arranged along the inside of the side door beam 3. The one end 6a side of this wire 6 is located near the door opening side end of the side door beam 3. At the same time, the other end 6b side of the wire 6 is locked to the door of the side door beam 3. Passing around the hinge 5 of the door 2 from the shaft support side end, the vehicle body side member 7 of the automobile 1 (door 2).

[0015] At this time, the wire 6 normally connects at least the opening/closing circuit around the hinge 5 of the door 2. The end of the side door beam 3 on the door open side with enough slack to allow movement. It is stretched from the vicinity to the vehicle body side member 7, and as shown in Figure 3, the side door beam 3 deforms inward to some extent due to the impact force from the side of the car 1. , tension is generated in the wire 6 as the wire 6 deforms.

[0016] With the above configuration, the door 2 receives impact force from the side of the vehicle 1 due to a collision or the like. As a result, the side door beam 3 is deformed. At the first slight change, tension is applied to wire 6. does not occur, but if the displacement of the side door beam 3 increases due to buckling, as shown in Fig. 3. As the side door beam 3 deforms, the inner wall of the side door beam 3 Tension is generated in the ear 6, and the impact force received by the side door beam 3 is caused by the wire 6. and is transmitted to the vehicle body side member 7.

[0017] Here, the wire 6 is very strong against tension, and its diameter is small so that it does not take up much space. I never take it. Moreover, since the wire 6 is flexible, its arrangement You can freely select the road (tension transmission route) and place it while avoiding obstacles inside the vehicle. In addition, even if it passes near the hinge 5, it will not be affected by the opening/closing rotation of the door 2. There is no fault.

[0018] In this way, according to the wire type side door beam structure of this embodiment, the automobile 1 When the impact force is received from the side, the impact force is absorbed only by the deformation of the side door beam 3. If this is not possible, tension will be generated in the wire 6 due to the deformation of the side door beam 3. The impact force is reliably transmitted and absorbed to the vehicle body side member 7 outside the door 2, and the wire 6 functions as a reinforcing structure for the side door beam 3. Therefore, against impact from the side This provides sufficient resistance against collisions, greatly improving safety in the event of a collision.

[0019] In addition, the impact force is transmitted to the vehicle body side member 7 by the wire 6, and the impact force is absorbed. , the hinge 5 can be installed as in the past by placing the burden on parts other than those around the door 2. There is no need to provide reinforcement near the opening, and the load on the side door beam 3 itself is reduced. can also be significantly reduced.

[0020]

[Effect of the idea]

As detailed above, according to the wire type side door beam structure of the present invention, the size A wire is placed along the side door beam, and one end of this wire is connected to the side door beam. At the same time, the other end of the wire is fixed near the open end of the door. Pass through the vicinity of the door shaft from the door shaft support side end of the ABeam to the vehicle body of the vehicle. The extremely simple structure of locking on the side reduces the impact force received by the side door beam. The advantage is that it can reliably transmit energy to the vehicle body, obtain sufficient strength, and ensure safety in the event of a collision. There is.
