Description

  The present invention relates to a slide door provided with an intermediate stopper mechanism for restricting movement of the slide door to a fully open position when a window glass of the slide door of the vehicle is open.

  If the sliding door is equipped with a window glass that can be opened and closed (lifted), if the sliding door is opened with the window glass open, the objects inserted in the opened window will be separated into the window frame of the sliding door and the pillar of the body. There is a risk of being pinched and damaged. In order to avoid this, it has been proposed to provide an intermediate stopper mechanism that stops the sliding door at an intermediate position in the opening direction when the opening degree of the window glass is a certain level or more.

Such an intermediate stopper mechanism is generally used for a vehicle sliding door that supports a window glass so that it can be opened and closed, and can swing between a retracted position and a stop position around an axis, and the opening degree of the window glass is above a certain level. A stopper lever that protrudes to the stop position and a stopper that restricts the stop position of the stopper lever are provided, and an intermediate striker that engages the stopper lever at the stop position is provided on the vehicle body. If the sliding door is moved in the opening direction when the opening of the window glass is above a certain level, the stopper lever at the sliding door stop position and the intermediate striker on the vehicle body abut, and the sliding door opening position is in the middle. Regulated by opening.

  When the sliding door having the intermediate stopper mechanism is vigorously moved in the opening direction, the stopper lever receives a strong rotational force by the intermediate striker and engages the stopper. For this reason, there is a possibility that the stopper lever is elastically deformed to change from surface contact to line contact, and a load is locally applied to cause the stopper lever or the stopper to be plastically deformed. Alternatively, there is a possibility that a force deviated from the direction orthogonal to the axis is applied to the rotating shaft and the bearing portion is deformed, and the impact load cannot be sufficiently received. In order to avoid this, the stopper lever and the stopper must be made of a high-strength material or increased in size, which is a cost increase factor.

  An object of the present invention is to obtain a sliding door having an intermediate stopper mechanism capable of improving impact resistance load regardless of the material surface of the stopper lever and the stopper or an approach of increasing the size.

  The present inventor has found that the conventional stopper lever and the stopper locking surface are each composed of a simple flat surface. Therefore, when an impact load is applied, the stopper lever is easily elastically deformed to change from surface contact to line contact. If the bearing surface is made up of a part of the cylindrical surface and the impact load is changed, the line contact is changed to the surface contact. The conclusion has been reached that the impact load can be improved and the present invention has been reached.

  That is, the present invention provides a vehicle sliding door that supports a window glass so that it can be opened and closed, and can swing between a retracted position and a stop position about an axis. A stopper lever that protrudes into the stopper and a stopper that restricts the stop position of the stopper lever are provided, and an intermediate striker that engages the stopper lever at the stop position to restrict the opening of the slide door is provided in the vehicle body. In a sliding door having an intermediate stopper mechanism, the stopper lever and one of the stoppers are in line contact with each other at the initial stage of the collision between the stopper lever and the intermediate striker, and change to surface contact with a cylindrical surface due to elastic deformation of the stopper lever. It is characterized in that a locking surface made of a part of the concave and convex cylindrical surface is provided.

  There is a degree of freedom in which the concave and convex cylindrical locking surface is provided. However, in a preferred embodiment, the stopper lever locking surface is constituted by a part of the concave cylindrical surface, and the stopper locking surface is formed by a convex cylindrical surface. It is the aspect which comprises from a part.

  To change the contact between the stopper lever and the stopper from line contact to cylindrical surface contact, the radius of curvature of the cylindrical surface of the stopper lever locking surface is larger than the radius of curvature of the cylindrical surface of the stopper locking surface in the free state. It is possible by any of the embodiments to be performed and the same embodiment. In the first mode, a mode in which the center positions of the radius of curvature of the stopper lever and the stopper match before the collision is possible, but in the second mode, they do not match in the state where both come into contact.

  According to the present invention, it is possible to improve the impact resistance load of the slide door having the intermediate stopper mechanism.

  In the following embodiments, front and rear and upper and lower mean the front and rear direction and the vertical direction of the vehicle. As shown in FIG. 1, a body 11 of a vehicle 10 is supported by a slide door 12 that opens and closes a passenger door 11a that opens on a side surface of the vehicle. The guide rail 11 b is a part of the sliding guide mechanism of the sliding door 12. The slide door 12 is provided with a window glass 13 that can be raised and lowered. The window glass 13 can be raised and lowered by a well-known window regulator (not shown). The window regulator may be either a manual operation type or an electric operation type, and the mechanism for opening and closing the slide door 12 may be either a manual operation type or an electric drive type.

  Inside the sliding door 12, a window glass interlocking wire pulling mechanism 14 for pulling the drive wire 14a is provided while the window glass 13 is fully opened from a predetermined intermediate opening. Such a window glass interlocking wire pulling mechanism 14 is well known. Further, the slide door 12 is provided with an opening / closing handle 15, and an unlocking lever (not shown) that pulls the drive wire 15 a when the sliding door 12 is operated when the slide door 12 is locked in the open position. )).

  A return pole 11c, an intermediate striker 11d, and a fully open striker 11e are fixed to the vehicle body 11 in order in the opening direction of the slide door 12 along the lower edge of the entrance 11a. A base plate 16 having an intermediate stopper mechanism and a fully open lock mechanism that cooperate with the pole 11c, the intermediate striker 11d, and the fully open striker 11e is fixed.

  As shown in FIGS. 2 to 4, the hook member 17 is pivotally attached to the base plate 16 by a shaft 17a, and the stopper lever 18 is pivotally attached by a shaft 18a. The hook member 17 and the stopper lever 18 constitute an intermediate stopper mechanism together with the intermediate striker 11d. The hook member 17 includes a drive arm 17b and a hook arm 17c. The drive arm 17b is coupled to the other end of the drive wire 14a from the window glass interlocking wire pulling mechanism 14, and is not shown. Thus, the drive wire 14a is urged to rotate in the direction A in which the drive wire 14a is pulled out from the outer cable 14b. The stopper lever 18 has a retracted position (FIGS. 3 and 4) that does not interfere with the intermediate striker 11d fixed to the body 11 around the shaft 18a, and a stopper position (FIG. 2) that engages (collises with) the intermediate striker 11d. And is urged to rotate in the stopper position direction B by spring means (not shown). The hook arm 17c of the hook member 17 engages with the lock arm 18b of the stopper lever 18 and acts to hold the stopper lever 18 in the retracted position against this biasing force.

  A cylindrical (columnar) stopper pin 19 is fixed to the base plate 16 as a stopper for restricting the rotation end of the stopper lever 18 in the stopper position direction. 5 and 6 show a detailed structure of the stopper lever 18 and the cylindrical stopper pin 19 around the single body. The stopper lever 18 is made of a press-molded product made of a metal material, and is in contact (collision) with a buffer material (not shown) provided on the intermediate striker 11d side on one side with respect to the radial direction from the shaft 18a. A contact member 18c is bonded, and a stopper arm 18e having a locking surface 18d made of a part of a concave cylindrical surface is provided on the other side. As shown in FIG. 5A, the curvature radius R of the locking surface 18d is larger than the curvature radius r of the cylindrical stopper pin 19, and when the locking surface 18d contacts (engages) the cylindrical stopper pin 19, When the stopper lever 18 is elastically deformed by the impact force of the collision with the intermediate striker 11d, it has a shape that changes to surface contact between the cylindrical surfaces. The center of curvature of the locking surface 18d and the center of curvature of the cylindrical stopper pin 19 may or may not match before the collision. The cylindrical stopper pin 19 has a complete cylindrical surface, but only a part thereof acts as a stopper.

  The return pole 11c (FIGS. 1 and 2) fixed to the body 11 comes into contact with the stopper lever 18 when the sliding door 12 is moved from the open position to the closed position when the stopper lever 18 is in the stopper position. It is rotated to the retracted position with respect to the intermediate striker 11d. When the stopper lever 18 rotates from the stopper position with respect to the intermediate striker 11d to the retracted position, the lock arm 18b and the hook arm 17c are engaged to hold the stopper lever 18 in the retracted position (FIGS. 3 and 4).

  The base plate 16 also supports a hook 20 and a ratchet 21 that constitute a full-open lock mechanism in cooperation with the full-open striker 11e so as to be rotatable by a shaft 20a and a shaft 21a, respectively. The hook 20 has a grip groove 20b for gripping and releasing the fully open striker 11e and a lock arm 20c, and is urged to rotate in a direction C for opening the fully open striker 11e by a spring means (not shown). The ratchet 21 has a stopper arm 21b that engages with the lock arm 20c, and a drive arm 21c that is coupled to a drive wire 15a that is output from the opening / closing handle 15, and the stopper arm 21b is locked by a spring means (not shown). It is urged to rotate in a direction D that engages with 20c (direction in which the drive wire 15a is pulled out from the outer kale portion 15b).

  The slide door provided with the intermediate stopper mechanism configured as described above operates as follows. When the window glass 13 is opened while the sliding door 12 is closed and the window glass 13 is fully closed, the drive wire 14a is pulled by the window glass interlocking wire pulling mechanism 14. That is, while the window glass 13 reaches the fully open position from the intermediate open position, the pulling state of the drive wire 14a is maintained, and the hook member 17 rotates in the clockwise direction in FIG. 3, and the hook arm 17c and the lock arm 18b. Is disengaged.

  The stopper lever 18 is urged to rotate in the B direction (clockwise) by the spring means. When the slide door 12 is fully closed, the return pole 11c prevents the rotation. In this state, when the slide door 12 is opened, the return pole 11c and the stopper lever 18 are eventually disengaged, and the stopper lever 18 is rotated in the B direction (clockwise) about the shaft 18a by the spring biasing force. The rotation end is restricted at a position where the locking surface 18d contacts the cylindrical stopper pin 19 (FIG. 2). The same condition occurs when the window glass 13 is opened with the opening degree of the sliding door 12 where the stopper lever 18 does not engage with the return pole 11c.

  In this state, when the slide door 12 is moved to the open position, the contact material 18c of the stopper lever 18 contacts (impacts) the intermediate striker 11d (the buffer material), and the slide door 12 is moved to the fully open position. Movement is restricted. That is, the intermediate stopper mechanism operates.

  When the slide door 12 is gently opened in the operation state of the intermediate stopper mechanism, the stopper lever 18 and the cylindrical stopper pin 19 are in line contact as shown in FIG. On the other hand, when the sliding door 12 is opened impactively, the stopper lever 18 is elastically deformed as a result of receiving an impact force by the intermediate striker 11d. That is, the stopper lever 18 and the cylindrical stopper pin 19 are in line contact with a part of a cylindrical surface having different radii of curvature, as shown in FIG. 5A, at the initial stage of the collision between the stopper lever 18 and the intermediate striker 11d. Eventually, when the stopper lever 18 is elastically deformed in a direction in which the radius of curvature of the locking surface 18d becomes smaller depending on the magnitude of the impact, it changes to surface contact by a part of the cylindrical surface, and the impact load can be received by the surface (FIG. 5 (B)). Therefore, the impact resistance load can be improved. Since the contact is made by the cylindrical surface, it is difficult for the stopper lever 18 to escape from the direction orthogonal to the shaft 18a.

  When the window glass 13 is not open, the stopper lever 18 is held in the retracted position (FIGS. 3 and 4). Therefore, when the sliding door 12 is opened, the stopper lever 18 does not come into contact with the intermediate striker 11d, and the hook 20 is clockwise (C direction) because the fully opened striker 11e relatively enters the gripping groove 20b. In the opposite direction). Then, the lock arm 20c is locked by the stopper arm 21b of the ratchet 21, whereby the slide door 12 is locked in the open position (FIG. 4). In the state shown in FIG. 4, when the lever of the opening / closing handle 15 is grasped, the drive wire 15a is pulled and the ratchet 21 is rotated clockwise (the direction opposite to the D direction), so that the stopper arm 21b and the lock arm 20c The engagement is released. As a result, the hook 20 rotates in the C direction, and the open position lock is released. Thereafter, when the slide door 12 is moved to the closed position, a closed position locking mechanism (not shown) is operated.

  In order to change the engagement mode of the stopper lever 18 and the stopper pin 19 from the line contact in the initial stage of the engagement (collision) to the cylindrical surface contact, the curvature of the locking surface 18d of the stopper lever 18 is shown in FIG. The radius R may be the same as the radius of curvature r of the cylindrical stopper pin 19. Even if they are the same, the center of curvature of the locking surface 18d and the center of curvature of the cylindrical stopper pin 19 are not appropriately matched so that the locking surface 18d and the cylindrical stopper pin 19 do not coincide with each other. By shifting in the direction, the contact mode between the stopper lever 18 and the cylindrical stopper pin 19 can be changed from line contact to cylindrical surface contact. 5A, a state in which the center of curvature of the locking surface 18d coincides with the center of curvature of the cylindrical stopper pin 19 may occur before the collision.

The intermediate stopper mechanism itself of the sliding door of the above embodiment shows an example. The present invention can be widely applied to any sliding door having a stopper lever that moves between a stopper position and a retracted position according to the opening of the window glass and a stopper that regulates the stopper position of the stopper lever.
