JP4867337B2 - Locking prevention structure for door outside handle - Google Patents

Description

  The present invention relates to an outside handle disposed outside a vehicle compartment of a vehicle door, and more specifically, when the door is deformed by an impact load from the side of the vehicle, the outside handle releases the door locking mechanism. The present invention relates to a structure for preventing operation in a state.

  The outside handle disposed outside the vehicle compartment of the vehicle door enables the door unlocking operation from the outside of the vehicle, and the door is locked via a link mechanism by a lever located on the back side of the outer panel. It is connected to. The outside handle is generally provided on the outer panel of the vehicle door so as to be able to swing, and is configured to release the lock by swinging the outside handle to the outside of the vehicle compartment. When a load is applied to the outer panel, the outside handle swings relatively with respect to the outer panel, the lock is released, and the door is unintentionally opened.

  Therefore, in order to prevent this unlocking, it is proposed to provide a counterweight on the other end side of the outside handle, or to provide a member that prevents the outside handle from swinging by moving or tilting with inertial force due to an impact. (See Patent Documents 1 and 2). However, since these use gravity and inertial force, they may not operate depending on the posture of the vehicle and the direction of impact load. In addition, since a mechanism for preventing unlocking is provided on the door handle and the outer panel to which the door handle is fixed, there is a possibility that these mechanisms themselves are damaged by an external impact and the prevention function does not operate sufficiently. there were.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.
FIG. 1 shows a rear side portion of a side surface of an automobile 1 provided with a vehicle door (rear door 2) according to an embodiment of the present invention, and FIG. 2 is a side view of the rear door 2 viewed from the vehicle interior side. . In the figure, a window 4 is provided in the upper part of the rear door 2, and a window glass 41 and a fixed glass 42 that can be raised and lowered with the sash 3 as a boundary are arranged on the window 4. An outside handle 5 for releasing the lock 6 of the rear door 2 from the outdoor side is disposed below the outdoor side of the fixed glass 42.

  As shown in FIG. 3, the rear door 2 is formed by joining an outer panel 21 and an inner panel 22 via a reinforcing member (not shown), and the inner side of the inner panel 22 is covered with an inner trim 23. A space 20 (FIG. 6) is formed between the outer panel 21 and the inner panel 22. The space 20 can absorb an impact from the side of the vehicle and can store the window glass 41. An inner handle 7 for releasing the lock 6 from the indoor side of the rear door 2, a window regulator (not shown) for raising and lowering the window glass 41, and the like are fixed to the inner panel 22.

  The sash 3 has a substantially H-shaped cross section having grooves on both sides in the vehicle front-rear direction so as to guide the window glass 41 and hold the fixed glass 42. The sash 3 extends from the fixing part 30 at the upper part of the window 4 to the inside of the rear door 2 through the belt line part, and is fixed to the inner panel 22 by the fixing parts 31 and 32 inside the rear door 2. (Fig. 4).

  As shown in FIGS. 4 to 6, the outside handle 5 is assembled to the case 51 together with the mechanism portion in advance to constitute a door handle assembly. The case 51 has an inner spherical basic shape in which a central portion is recessed toward the vehicle interior side with respect to a circular outer peripheral portion. A pair of square holes 52a and 52b penetrating the upper part of the case 51 are provided, and a support portion 53 is provided on the back side (vehicle interior side) of the case 51 so as to surround the square holes 52a and 52b. Has been. The case 51 is fitted into the mounting hole 21 a from the outside of the outer panel 21, while the bolt 51 b is inserted from the inside into the fixed seat surface 21 b and screwed into the nut 51 a held by the case 51. It is fixed to the panel 21. The attachment work from the inside is performed through the work opening 24 of the inner panel 22.

  The outside handle 5 includes a grip portion 54 located on the outer surface of the vehicle, a recess portion 55 located on the back surface side of the vehicle to allow insertion of a finger, and a pair of arm portions 56a and 56b extending from both sides thereof. Bearing portions 57a and 57b and a pair of levers 58a and 58b extending from the vicinity of the bearing portions 57a and 57b to the vehicle interior side are integrally formed at the upper ends of the arm portions 56a and 56b. Then, the pair of arm portions 56 a and 56 b are inserted into the square holes 52 a and 52 b of the case 51, and the bearing portions 57 a and 57 b are engaged with the support shaft 53 a provided on the support portion 53 of the case 51 to be supported. Thus, the outside handle 5 can swing between a lock position (5) indicated by a solid line and a lock release position (5r) indicated by a two-dot chain line in FIG. The outside handle 5 is unlocked by the return spring 53b by hooking the end of the return spring 53b supported and held in the middle between the support shafts 53a on both sides to the bases of the levers 58a and 58b. It is biased in the direction of swinging from the position (5r) toward the lock position (5).

  Of the pair of levers 58a and 58b of the outside handle 5, the lever 58a located on the right side in FIG. 5 as viewed from the vehicle interior side is a lever for unlocking, and a rubber cap is fitted on the surface thereof. There is one arm 59a of the release lever 59 on its lower surface. An inner cable 60b of the control cable 60 is swingably connected to the other arm 59b of the release lever 59. The inner cable 60b is connected to a latch (not shown) of the lock 6, and the release lever 59 is biased by a return spring 59c in a locking direction which is counterclockwise in FIG. The release lever 59 and the return spring 59c are assembled to the plate 59d to form a lever assembly, and the end of the outer cable 60a of the control cable 60 is held by the holder 59e at the upper end of the plate 59d.

  Then, by placing a finger on the grip 54 of the outside handle 5 and swinging the outside handle 5 outward in the vehicle width direction, the lever 58a depresses one arm 59a of the release lever 59, and the release associated therewith. When the lever 59 rotates, the other arm 59b pulls the inner cable 60b of the control cable 60 and the lock 6 can be released. After the lock 6 is released, when the outside handle 5 is released, the return spring 53b releases the outside. The handle 5 returns to the original position, and the release lever 59 is also returned to the original position by the return spring 59c.

  In the outside handle 5 configured as described above, when the door is deformed by an impact load from the side of the vehicle, the outside handle 5 swings to the unlock position (5r) due to the deformation, and the door 2 is As a structure for preventing the release, a lock release preventing lever 58b and a release preventing member 8 positioned on the vehicle cabin side of the lever 58b are provided.

  The unlocking lever 58b is a lever 58b located on the left side in FIG. 5 of the pair of levers 58a and 58b of the outside handle 5. The outside handle 5 includes the pair of levers 58a and 58b. The case 51 has a symmetrical shape centered on a plane orthogonal to the swing axis (53a), and the left and right doors 2 share components.

  As shown in FIGS. 5 and 6, the release prevention member 8 includes a base portion 80 and a main body portion 81 extending rearward from the base portion 80 in the vehicle front-rear direction, and is fixed to the sash 3 at the base portion 80. Yes. The release preventing member 8 is formed, for example, by bending a sheet metal. In the illustrated example, the main body 81 has a U channel shape, and the base end side is widened with respect to the distal end side, whereby the base portion 80 is formed. Sufficient bending strength. Further, a part of the sash 3 is cut away at a place where the release preventing member 8 is fixed, and the release preventing member 8 is fixed to the central portion of the sash 3.

  An inclined release blocking surface 81a is formed on the upper portion on the distal end side of the release blocking member 8 so as to face the lever 58b and increase in a direction away from the lever 58b. The release preventing surface 81a has a swinging range so as not to interfere with the unlocking operation during normal use by the outside handle 5, that is, so as not to intersect with the swinging range (58r) of the lever 58b accompanying the releasing operation. (58r) is provided in close proximity to each other, but for the reasons described later, the height of the release prevention surface 81a on the side away from the lever 58b is substantially equal to the lever 58b in the locked state, and the lever 58b It arrange | positions so that it may become low as it approaches.

  Next, the operation of the lock release preventing structure for the outside handle 5 configured as described above will be described with reference to FIGS. 6 and 7.

  When an impact load is applied from the side of the vehicle, the outer panel 21 positioned outside the door 2 is deformed first, and the outside handle 5 fixed to the outer panel 21 is also moved to the vehicle interior side. Because of the space 20 between the outer panel 21 and the inner panel 22, the inner panel 22 is delayed in deformation start time and the deformation amount is reduced. Accordingly, the sash 3 assembled to the inner panel 22 and the release preventing member 8 fixed to the sash 3 have a smaller amount of movement at the initial stage of collision than the outside handle 5.

  For example, when it is assumed that the outer handle 21 is moved by the movement amount Xo from the normal position (5) indicated by the two-dot chain line in FIG. 7 to the vehicle interior side (5x) indicated by the solid line along with the deformation of the outer panel 21. The release prevention member 8 moves to the vehicle interior side (8x) by a smaller movement amount Xi. At the same time, the lever 58b (58x) of the outside handle 5 (5x) is positioned above the release prevention member 8 (8x), and the release prevention member 8 (8x) swings the lever 58b (58x) in the unlocking direction. The movement is restricted and the erroneous opening of the door 2 is prevented.

  Further, when the lever 58b of the outside handle 5 swings in the unlocking direction before reaching the release preventing member 8, the lever 58b is guided by the inclined release preventing surface 81a, Along with the movement to the vehicle interior side, it is forcibly returned to the lock position (58x), and the door 2 is prevented from being erroneously opened more reliably.

  In the above-described lock release prevention structure, the sash 3 to which the release prevention member 8 is fixed is required to have high rigidity because it itself has a role of guiding the raising and lowering of the window glass 41, and is less susceptible to deformation, and the release prevention member. However, it is also possible to fix the release prevention member 8 to the inner panel 22 directly or via another bracket, or to form the release prevention surface 81a.

  Further, the release prevention member 8 is provided on the side opposite to the side of the sash 3 that guides the window glass 41 that can be raised and lowered, and a part of the sash 3 is cut away so that the release prevention member 8 is located at the center of the sash 3 Even if the lever 58b abuts against the release preventing member 8 and a load is applied to the release blocking member 8, the load is hardly affected on the side of the sash 3 that guides the window glass 41, and the window glass 41 is not raised or lowered. .

  In the above embodiment, the case where the release preventing structure is configured by the lever 58b different from the unlocking lever 58a and the release preventing member 8 is shown, but the lever (58a) that directly performs the unlocking operation and the release preventing are shown. It is also possible to configure a release preventing structure with the members. At that time, in order to avoid the intersection of the release lever 59 operated by the lever 58a and the release prevention member (8), an extension portion is appropriately provided on the side of the tip portion of the lever 58a, and the extension portion is released. It may be restricted or guided by a blocking member.

In the above embodiment, the case where the lock release prevention structure is implemented in the cable type latch (lock release mechanism) using the control cable 60 has been described. However, the present invention may be implemented in the rod type latch. Is possible. Further, the lock release preventing structure of the present invention can be used in combination with the counterweight (attached to the upper end of the lever) that swings the outside handle 5 in the locking direction by the inertial force when an impact load is applied.
