Abstract

PURPOSE:To prevent the flexture of the opening part of a door and improve the rigidity of a vehicle body by mounting rollers used to position a door in the horizontal and the perpendicular direction thereof, engaging parts with these rollers and a forced locking mechanism and forcedly engaging the door catch with the door. CONSTITUTION:Inside the door of a vehicle a reinforcement 3 ranges from the door hinge metal 1 to the door catch 2 at the side of the vehicle body. The reinforcement 3 has at the end thereof a locking mechanism 4 engaged with the door catch 2. The door catch 2 has a horizontally positioning roller 5, a perpendicularly positioning roller 6 and a door locking roller 7. The reinforcement 3 has both a perpendicularly positioning roller contact face 11 and a horizontally positioning roller engaging groove 12 formed and also both a door hook 13 and a locker 14 attached to the reinforcement 3 together with springs 15 and 16 using pins 17 and 18, respectively. A door lock release rod 19 is engaged with the locker 14 at the middle part thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improving the body rigidity of a motor vehicle, particularly an open car.

The body of an automobile, especially in the case of an open car with a monocoque structure, tends to flex at the door opening, impairing running stability and riding comfort.

Disadvantages between conventional technology and conventional technology: In the past, reinforcing materials were added to the side sills and other parts of convertible cars in order to prevent the car body from bending at the door openings, but the height of the section of the part was limited. In addition, a method of adding a roll bar-like structural member to the upper part of the car body has been used to improve the torsional rigidity of the car body, but this impairs the sense of openness of an open car. .

Means for Solving Problems The present invention aims to reinforce the door and utilize it as a reinforcement for the rigidity of the vehicle body when the head is closed. In addition, a locking mechanism is provided, and a fi side is provided at the meshing part between the door and the door catch to allow correction of deflection.
Even if the vehicle body is bent, the door I#IlfI
The aim is to ensure smooth and reliable implementation.

EXAMPLES Hereinafter, examples of the present invention will be described in detail with reference to the accompanying drawings. In the twelfth step, a reinforcing material 3 is added to the inside of the automobile door from the door hinge metal l to the position of the door catch 2 on the vehicle body side. The tip of this reinforcing material 3 has a door and
A locking mechanism 4 that engages with the catch 2 is provided.

2, 3, and 4 are a plan view, a side view, and a front view of the door catch 2 attached to the vehicle body. The door catch 2 has a front and rear positioning roller 5, a vertical positioning roller 6, and a door lock roller 7.
is installed. Further, each roller is capable of sliding in the axial direction, and is held at its respective neutral position by springs 8 on both sides. The door catch 2 is fixed to the door land portion of the vehicle body 10 by pins 1 to 9.

5, 6, and 7 are a plan view, a side view, and a front view of the locking mechanism 4. FIG. The reinforcing material 3 has an upper and lower positioning roller contact surface 11 and a front and rear positioning roller engagement surface 1.
In addition, the door hook 13 and the locker 14 are attached to the spring 1 in the groove provided in the reinforcing member 3.
5 and spring 16 as well as pin 17 and pin 18
It is attached to. Here spring 15 is the door
The hook 13 is biased in the opening direction, and the spring 18 biases the locker 14 in the locking direction. A door lock release rod 19 is engaged with the middle part of the locker 14, and the door is released by the door lock release rod 1.
9 is done by pulling the locker 143. Reinforcement material 3
is provided with a door lock rod 2o and a support member 21, and a spring 2 attached to this support member 21
2, the door/lock loft 20 is urged toward the locker 14 side.

FIGS. 8 and 9 [A is a schematic view of the mechanism for operating the door lock loft 20, and is a view of the reinforcing material inside the door looking downward from above.

In Fig. 8, the door lock handle 23 is the reinforcing material 3.
The lug 24 is attached to the lug 24 by a pin 25, and one end of a rod 26 is attached to the door/mouth/opening/handle 23 by a pin 27. A bell crank 28 is attached near the center of the reinforcing member 3 so as to be rotatable around its axis, and the above-mentioned rod 2
The other end of the bell crank 28 and one end of the bell crank 28 are connected by a pin. Further, the root portion of the door lock loft 20 is connected with a pin to the other end of the bell crank 28.

FIG. 8 shows the door lock handle 23 in its retracted state, flush with the door lining 29.

FIG. 9 shows a state in which the door lock handle 23 is rotated in the locking direction, that is, forward.
The lock loft 20 forcibly presses the door hook 13 in the locking direction to lock it. In the case of this embodiment, it is easiest to apply operating force while seated, and in the case of the driver's seat, in order to prevent interference with the steering wheel, the door and
The lock handle 23 is mounted by setting the angle of the lug 24 so that it operates diagonally forward, inward, and upward. Further, 1. An embodiment in which the door/mouth/pull rod 20 is operated using an electric motor, a hydraulic actuator, an engine intake negative pressure actuator, etc. is also possible.

Figures 10, 11, 12, and 13 are schematic diagrams of the operation when closing the door, and the front and rear positioning rollers 5
and represents the relationship between the door lock roller 7 and the lock fit 14.

The 101st ffl closes the door from the open state of the door hook 13, and the door lock roller 7 closes the door)I
After passing through the tip of the fiber 13, it is in contact with the protrusion on the base side.

FIG. 11 shows that the door is further opened and the door hook 13 is pushed by the door lock roller 7 and rotates to the lock side.
This is #R bad, which is engaged with the locker 14 in the half-lock position.

FIG. 12 shows that after the half-locked state, the door lock handle 23 is operated to lock the door lock rod 20.
In this case, if the car body is slightly bent due to the difference in height of the ground under each wheel, the number of passengers, etc., the door locks will be forced to lock. is guided by the longitudinal positioning roller 5 and the vertical positioning roller 6, and operates in the locking direction while correcting the deflection of the vehicle body. As mentioned above, the reason why the rollers 5, 6 and 7 of the door catch 2 are made slidable in the axial direction is to cope with this deflection correction operation. For example, when the locking device tIII4 initially starts to engage at the rear of the door catch 2 due to the deflection of the vehicle body, the vertical positioning roller 6 contacts the front side of the vertical positioning roller contact surface 11. Thereafter, this deflection is corrected by a forced locking operation, but the vertical positioning roller 6 slides rearward by the initial deflection amount and does not interfere with this corrective action.

Figure 13 shows the state in which the door lock has been completed, and when the door lock handle 23 is retracted from this state, the door lock is completed.
The lock rod 2o is retracted at the position r11 shown by the dotted line, and the door can subsequently be unlocked.

If there is no bending of the vehicle body, simply closing the door will cause the door to move to the lock position, similar to conventional vehicle bodies.

Effects of the Invention Since the present invention is constructed as described above, by using the door to position the high position of the door closing portion of the vehicle body in the longitudinal and vertical directions, the deflection of the vehicle body can be effectively prevented.
You can improve your 4-sexuality.

In addition, by having a side that forces the door to lock, and by using rollers that slide in the axial direction to position the door in the front, rear, and vertical directions, the door can be locked even if the vehicle body is bent. Kaida can be implemented smoothly and reliably.
