JP-A-8-198122 JP 2006-315609 A

  In such a structure of the steering hole cover, for example, considering the reduction of parts management man-hours and the improvement of workability in the vehicle assembly process, as a part delivery form from the parts manufacturer to the car manufacturer's production line, On the other hand, there is a demand to deliver the steering hole cover assembly in a so-called temporarily assembled state in which the accessory parts such as the clamp member and the bracket are temporarily assembled.

  However, the conventional structures represented by Patent Documents 1 and 2 do not consider any temporary assembly of the accessory parts such as the clamp member and the bracket with respect to the steering hole cover. There is still room for improvement in improving workability in the vehicle assembly process.

  Also, since the steering hole cover is often made of rubber, even if the bracket can be temporarily assembled using the flexibility of the steering hole cover itself, the parts distribution process As a result, the bracket may fall off the steering hole cover, and the intended purpose cannot be achieved.

  The present invention has been made paying attention to such problems, and at least a bracket is temporarily assembled with respect to the steering hole cover, and the steering hole cover assembly is designed so that the bracket is not easily detached. The structure is provided.

  The present invention is a structure of a steering hole cover assembly that covers a shaft insertion hole while surrounding a steering shaft that penetrates a shaft insertion hole of a dash panel of an automobile on the indoor side. A steering hole cover formed with an annular flange portion projecting outward from one end of the opened deformed cup-shaped cover body, and the steering hole cover that is overlapped on the flange portion to fix the steering hole cover to the dash panel And an annular bracket.

  Further, an overhanging convex portion is formed on the outer periphery of the cover body so as to project outward with a minute gap between the flange portion and the bracket when the bracket portion is overlaid on the flange portion. A notch that can receive the protruding protrusion is formed.

  In addition, by rotating the cover body and the bracket relative to each other in a direction to prevent detachment in a state in which the notch receives the protruding protrusion, a portion of the bracket adjacent to the notch is the minute gap. The bracket is sandwiched between the projecting convex portion and the bracket to prevent the bracket from being detached from the cover body.

  In this case, as a desirable mode, as described in claim 2, the cover body is located at a position away from the projecting convex portion in a circumferential direction of the cover body and at a boundary portion between the cover body and the flange portion. A slot portion is formed to sandwich a part of the bracket when the cover body and the bracket are relatively rotated in the direction of preventing separation.

  As a more desirable aspect, as described in claim 3, a stopper portion is formed on each of the flange portion and the bracket, and when the cover body and the bracket are relatively rotated in the separation preventing direction, The stopper portions are engaged with each other so that the relative position between the cover body and the bracket is regulated.

  In this case, as described in claim 4, either one of the stopper portions on the flange portion side and the bracket side sandwiches the other stopper portion from both sides, More preferably, the engagement between the stopper portions restricts the relative position in the direction in which the steering hole cover and the bracket are separated from each other and in the opposite direction.

  Furthermore, as a desirable mode, as described in claim 5, the projecting convex portion is formed as a tongue-like shape parallel to the flange portion.

  As another desirable mode, as described in claim 6, the bracket is formed with a stopper portion, and when the cover main body and the bracket are relatively rotated in the separation preventing direction, the protruding convex portion is formed. By getting over the stopper portion, both engage with each other, and the relative position between the cover body and the bracket is regulated.

  As a more desirable aspect, as described in claim 7, the projecting convex portion is formed as a rib-like member extending in the axial direction of the cover body.

  As another aspect, a soft insulator is attached in advance to a seating surface of the flange portion with respect to the dash panel.

  As another aspect, as described in claim 9, a clamp member for connection to the steering shaft is mounted in advance on the outer periphery of the other end of the cover body.

  According to the present invention, in a state where the steering hole cover is not attached to the dash panel, a part of the bracket is sandwiched between the projecting convex portion and the flange portion on the steering hole cover side, and the bracket from the steering hole cover Therefore, the bracket does not fall off from the steering hole cover in the parts distribution process or the transport process before the steering hole cover is attached to the dash panel. Therefore, it can greatly contribute to the reduction of the man-hours for parts management and the improvement of workability in the vehicle assembly process described above.

  According to the second aspect of the present invention, since the slot portion having the same function is formed separately from the bracket detachment preventing function by the projecting convex portion and the flange portion, the bracket from the steering hole cover is formed. The effect of preventing the detachment becomes more remarkable.

  According to the third and sixth aspects of the invention, the effect of restricting the relative position by the stopper portion is exhibited separately from the function of preventing the bracket from being detached by the protruding convex portion and the flange portion. The effect of preventing detachment becomes even more remarkable.

  According to the fourth aspect of the present invention, the engagement between both the stopper portions restricts the relative position in the direction in which the steering hole cover and the bracket are separated from each other and in the opposite direction. The relative position regulation effect by the part becomes more remarkable.

  According to the fifth aspect of the present invention, since the projecting convex portion is formed as a tongue-like piece, the effect of restricting the relative position particularly in the overlapping direction of the flange portion and the bracket becomes remarkable.

  According to the invention described in claim 8, since the insulator is previously attached to the seating surface of the flange portion with respect to the dash panel, a plurality of parts in which the bracket and the insulator are added to the steering hole cover are managed as one part. Therefore, the effect of reducing the man-hours for parts management and improving the workability in the vehicle assembly process becomes more remarkable.

  According to the ninth aspect of the present invention, since the clamp member for connection to the steering shaft is attached in advance to the outer periphery of the other end of the cover body, the bracket, the insulator and the clamp member are attached to the steering hole cover. Since the added multiple parts can be managed and distributed as one part, the effect of reducing the part management man-hours and improving workability in the vehicle assembly process becomes even more remarkable.

  1 to 6 show a more specific first embodiment for implementing a steering hole cover assembly according to the present invention, and particularly FIG. 1 shows an application example of a steering hole cover to a steering shaft. FIG. 2 is an exploded perspective view of the steering hole cover assembly including the steering hole cover shown in FIG. 1 as a main element.

  As shown in FIG. 1, the upper shaft 3 a supported by the jacket tube 2 of the steering column 1 is connected to the intermediate shaft 3 b via the universal joint 4. The intermediate shaft 3b is also connected to the lower shaft 3c via the universal joint 5. The upper shaft 3a, the intermediate shaft 3b, and the lower shaft 3c form the steering shaft 3, and the intermediate shaft 3b penetrates the dash panel 6 that separates the engine room and the room from the vehicle body. . The lower shaft 3c is connected to a steering gear (not shown), and a steering wheel (not shown) is connected to the tip of the upper shaft 3a as is well known.

  More specifically, a shaft insertion hole 6a is formed in the dash panel 6, and the intermediate shaft 3b passes through the shaft insertion hole 6a. A steering hole cover 7 is inserted in advance so as to surround the intermediate shaft 3b. After the assembly of the steering shaft 3 is completed, the lower end portion of the steering hole cover 7 is fixed to the dash panel 6 using a bracket 8 described later, and the upper end portion of the steering hole cover 7 is used a clamp member 9 described later. Connected to the intermediate shaft 3b.

  A seal member 11 for allowing the rotation of the intermediate shaft 3b is interposed between the intermediate shaft 3b and the upper end portion of the steering hole cover 7 in the same manner as described in Patent Document 1 above. .

  Here, for the purpose of reducing the number of parts management man-hours, etc., as a part delivery form from the parts maker to the car maker's production line, auxiliary parts such as the clamp member 9 and the bracket 8 are also temporarily assembled to the steering hole cover 7. As mentioned above, there is a request for delivery in the same state.

Therefore, in the present embodiment, the steering hole cover 7 as a main component and the auxiliary components such as the bracket 8 and the clamp member 9 are temporarily assembled to the steering hole cover assembly 10, and the steering hole cover assembly 10 is referred to as the steering hole cover assembly 10. Details of the hole cover assembly 10 are shown in FIG.
To do.

  A steering hole cover assembly 10 shown in FIG. 2 includes a steering hole cover 7, a bracket 8 for fixing the steering hole cover 7 to the dash panel 6 of FIG. 1, and the steering hole cover 7 as an intermediate shaft 3 b of the steering shaft 3. The clamp member 9 is connected to the steering hole cover 7 and the soft insulator 12 is attached to the steering hole cover 7 in advance.

  FIG. 3 is a plan view of the steering hole cover 7 shown in FIG. 2 in a state where the bracket 8 is superimposed on the flange portion 14, and FIG. The top view in the state rotated relatively in the removal prevention direction is shown. 5 is an enlarged cross-sectional view taken along the line AA in FIG. 4, and FIG. 6 is an enlarged cross-sectional view taken along the line BB in FIG.

  The steering hole cover 7 shown in FIG. 2 is formed of a predetermined rubber material such as EPDM so as to have flexibility, and has a large diameter among the deformed cup-shaped cover main body 13 whose both ends are open. An annular flat flange portion 14 projecting outward is integrally formed at the open end on the side. Further, the open end on the small diameter side of the cover body 13 is formed as a cylindrical small diameter cylindrical portion 15 for connection with the intermediate shaft 3b shown in FIG. As apparent from FIGS. 2 and 3, the small diameter cylindrical portion 15 is cylindrical, whereas the cover body 13 including the flange portion 14 is attached to the dash panel 6 shown in FIG. 1. In consideration of the posture and the like, it is formed as a non-circular one, and the small diameter cylindrical portion 15 is eccentric with respect to the cover body 13.

  A clamp member 9 for connection to the intermediate shaft 3b is attached to the small diameter cylindrical portion 15 in a temporarily tightened state. The clamp member 9 has a known structure in which the wire 9b positioned outside the small-diameter cylindrical portion 15 is wound and tightened by the clamping operation of the clamp bolt 9a.

  The flange portion 14 functions as a seating surface for the dash panel 6, and a deformed annular and soft insulator 12 made of, for example, sponge rubber or the like is attached in advance to the back surface of the flange portion 14. The contour shape of the insulator 12 is formed in substantially the same shape as that of the flange portion 14. The insulator 12 is in close contact with the peripheral edge portion of the shaft insertion hole 6a shown in FIG. 1 in a state where the steering hole cover 7 is properly assembled.

  In addition to FIGS. 2 and 3, as shown in FIG. 5, a substantially trapezoidal tongue piece in a plan view is formed on a part of the outer peripheral surface of the cover body 13 with a small gap G between the cover body 13 and the flange portion 14. An overhanging convex portion 16 that protrudes outward in a shape is formed so as to protrude substantially parallel to the flange portion 14. Further, a single stopper portion 17 having a rectangular bead shape or a bar shape is formed on a part of the upper surface of the flange portion 14 so as to protrude in the radial direction in the vicinity of the projecting convex portion 16. A bracket 8 for attaching the steering hole cover 7 to the dash panel 6 is disposed on the flange portion 14 where the single stopper portion 17 is formed.

  The bracket 8 is a light metal material formed by, for example, an aluminum die casting method, and as shown in FIG. 5 in addition to FIGS. 2 and 3, the contour shape forms the same deformed annular shape as the flange portion 14. The upper wall portion 8a and the peripheral wall portion 8b are formed to have a substantially L-shaped cross section.

  On the other hand, the inner peripheral shape of the upper wall portion 8a of the bracket 8 does not match the shape of the root portion of the flange portion 14 with respect to the cover body 13 from the viewpoint of the bending characteristics required for the steering hole cover 7, for example. Instead, as shown in FIGS. 3 and 4, a so-called irregular shape is obtained in which a gap Q is secured between the base portion of the flange portion 14 in a part of the circumferential direction. Further, flange portions 8c projecting outward are projected at four locations in the circumferential direction of the bracket 8, and bolt holes 8d into which mounting bolts (not shown) are inserted are formed in the flange portions 8c. .

  Furthermore, as shown in FIGS. 2 to 4, a part of the inner periphery of the upper wall part 8 a of the bracket 8 is formed with a notch part 18 that can receive the protruding convex part 16. A substantially triangular stopper portion 19 that protrudes to the inner peripheral side at a distance is formed. More specifically, as shown in FIG. 3, the protruding portion 16 protrudes from a part of the upper wall portion 8 a of the bracket 8 in a state where the bracket 8 is overlapped from above the flange portion 14 so that the contour shapes of both are coincident. The notch 18 which can receive is formed. Similarly, a stopper portion 19 on the bracket 8 side is formed so as to project at a position where it does not interfere with the stopper portion 17 on the flange portion 14 side in a state where the cutout portion 18 receives the protruding protrusion 16.

  On the other hand, FIG. 6 shows an enlarged cross-sectional view along the line BB in FIG. As shown in FIGS. 4 and 6, the upper wall of the bracket 8 is located at the boundary between the cover main body 13 and the flange portion 14 at a position relatively far from the projecting convex portion 16 in the circumferential direction of the cover main body 13. A slot portion 20 that can receive a part of the portion 8a is formed.

  Therefore, in the structure of the steering hole cover assembly 10 configured as described above, as shown in FIGS. 2 and 3, the protruding convex part 16 on the cover body 13 side of the steering hole cover 7 and the notch part 18 on the bracket 8 side are provided. The brackets 8 are overlapped from above the flange portion 14 while matching the positions of. The state where the flange portion 14 and the bracket 8 are overlapped is the state shown in FIG. In this case, if the positions of the projecting convex portion 16 and the bracket 8 are the same and do not interfere with each other, the stopper portion 17 on the flange portion 14 side and the bracket 8 side stopper portion 19 do not interfere with each other.

  As shown in FIG. 3, in a state where the flange portion 14 and the bracket 8 are overlapped, for example, the bracket 8 is attached to the flange portion 14 and the bracket 8 is prevented from being detached from the steering hole cover 7, that is, the arrow in FIG. Rotate a predetermined amount in the M direction.

  In this case, it is assumed that the flange portion 14 is slightly bent so that the stopper portion 19 on the bracket 8 side gets over the stopper portion 17 on the flange portion 14. By doing so, when the stopper portion 19 on the bracket 8 side gets over the stopper portion 17 on the flange portion 14 side, both engage with each other, while the portion of the upper wall portion 8a of the bracket 8 adjacent to the notch portion 18 As shown in FIGS. 4 and 5, the gap 14 is sandwiched between the flange 14 and the protruding protrusion 16 in the minute gap G.

  In this state, the upper wall portion 8a of the bracket 8 is sandwiched between the flange portion 14 and the overhanging convex portion 16 in the minute gap G, and the flange portion is used for engaging the stopper portions 17 and 19 with each other. The relative position between the bracket 14 and the bracket 8 is restricted, and at least the relative rotation in the direction opposite to the separation preventing direction (the direction of the arrow M in FIG. 3) is prevented.

  On the other hand, because of the irregular shape of the inner peripheral surface of the upper wall portion 8a of the bracket 8 described above, the bracket 8 is rotated in the direction to prevent separation (in the direction of arrow M in FIG. 3) with respect to the flange portion 14. In the state 4, a part of the upper wall portion 8 a in the bracket 8 is sandwiched between the slot portions 20 as shown in FIG. 6. This means that the slot portion 20 also exhibits a function equivalent to the function of sandwiching the bracket 8 by the protruding convex portion 16.

  Therefore, the bracket 8 is sandwiched between the steering hole cover 7 at two locations in the circumferential direction of the steering hole cover 7, and the flange portion 14 and the bracket 8 are engaged with each other because the stopper portions 17 and 19 are engaged with each other. Relative positioning is performed to prevent relative rotation in the opposite direction to the direction of preventing both from separating (in the direction of arrow M in FIG. 3). Therefore, in the state of FIG. 4, the bracket 8 is not easily detached from the steering hole cover 7, and the state in which the bracket 8 is temporarily held by the steering hole cover 7 can be stably maintained.

  Further, the clamp member 9 attached to the small diameter cylindrical portion 15 of the steering hole cover 7 is not easily detached by appropriately adjusting the clamping bolt 9a.

  As described above, in the steering hole cover assembly 10 of the present embodiment, the insulator 12 is attached to the flexible steering hole cover 7 in addition to the bracket 8 and the clamp member 9 which are hardware parts. However, the bracket 8, the clamp member 9 and the like are not easily detached, and the steering hole cover assembly 10 can be substantially used as one part for distribution and transportation.

  Here, in the above embodiment, in addition to the function of sandwiching a part of the bracket 8 between the flange portion 14 and the projecting convex portion 16 shown in FIG. 5, the bracket to the slot portion 20 shown in FIG. Although a part of the sandwiching function of FIG. 8 is used together, another set of the structure of FIG. 5 can be adopted instead of the structure of FIG. 6 as necessary.

  FIG. 7 shows a second embodiment of the steering hole cover assembly according to the present invention, and the same reference numerals are given to the portions common to FIG. 4 which is the first embodiment.

  In the second embodiment shown in FIG. 7, another bead-shaped second stopper portion 21 is connected to the stopper portion 17 in a portion close to the stopper portion 17 on the flange portion 14 side and close to the protruding convex portion 16. It differs from that of FIG. 4 in that it is formed in parallel.

  In this second embodiment, as apparent from comparison with FIG. 4, the bracket 8 superimposed on the flange portion 14 is rotated by a predetermined amount in the direction of preventing separation (the direction of the arrow M in FIG. 3), and the bracket 8 when the portion adjacent to the notch 18 in the upper wall 8a is sandwiched between the flange 14 and the projecting protrusion 16, the stopper 19 on the bracket 8 side replaces the stopper 17 on the flange 14 side. At the same time, the second stopper portion 21 is engaged with the base portion of the stopper portion 19 on the bracket 8 side so that the second stopper portion 21 comes into contact therewith.

  For this reason, as shown in FIG. 7, in a state where a portion of the bracket 8 adjacent to the notch 18 is sandwiched between the flange portion 14 and the projecting convex portion 16, the stopper portion 19 on the bracket 8 side is simultaneously flanged. It will be in the state pinched | interposed by the stopper part 17 by the side of the part 14, and the 2nd stopper part 21 from both sides.

  As a result, not only the position restriction in the direction opposite to the direction in which the bracket 8 is detached from the flange portion 14 (the direction of arrow M in FIG. 3) but also the position restriction in the direction of prevention of separation (in the direction of arrow M in FIG. 3) is simultaneously performed. The position is regulated at the position where the position is regulated in both directions. Therefore, in the second embodiment, the position restriction effect of the bracket 8 with respect to the flange portion 14 is further improved as compared with the first embodiment shown in FIG.

  Here, instead of the structure in which the stopper portion 19 on the bracket 8 side is sandwiched from both sides by the stopper portion 17 on the flange portion 14 side and the second stopper portion 21, for example, two stopper portions 19 on the bracket 8 side are formed side by side, The same effect can be expected even if the single stopper portion 17 on the flange portion 14 side is sandwiched from both sides by the pair of stopper portions 19.

  8 to 13 show a third embodiment of the steering hole cover assembly according to the present invention, and the same reference numerals are given to the parts common to FIGS. 3 and 4 which are the first embodiment. is there.

  FIG. 8 is a plan view showing a state before the bracket 8 is prevented from being detached from the flange portion 14 of the steering hole cover 7, and FIG. 9 is an enlarged view of a portion C in FIG. 10 shows a plan view after the bracket 8 is prevented from being detached from the flange portion 14 of the steering hole cover 7, and FIG. 11 shows an enlarged view of a D portion in FIG. Further, FIG. 12 shows an enlarged cross-sectional view along the line EE in FIG. 11, and FIG. 13 shows an enlarged cross-sectional view along the line FF in FIG.

  As shown in FIG. 8, instead of the tongue-shaped projecting convex portion 16 shown in FIG. 3, a square bead-shaped projecting convex portion 26 extending in the axial direction is formed on a part of the outer peripheral surface of the cover body 13. Has been. More specifically, as shown in the sectional view of FIGS. 12 and 13 in addition to the enlarged view of FIG. 9, a rectangular bead-like projecting protrusion is formed on a part of the outer peripheral surface of the cover main body 13 so that the height gradually decreases downward. A portion 26 is formed to protrude. Further, a recess 22 is formed at a position corresponding to the protruding protrusion 26 in the flange portion 14.

  On the other hand, the upper wall portion 8a of the bracket 8 shown in FIG. 8 is formed with a notch 23 as shown in an enlarged view in FIG. 9, and the notch 23 is formed on the inner peripheral side of the notch 23. A claw piece-like stopper portion 24 is formed so as to protrude in the circumferential direction in such a manner as to narrow the opening width of 23. As shown in the enlarged cross-sectional view of FIG. 13, the stopper portion 24 is formed with a mountain-shaped raised portion 24 a at an intermediate portion of the protruding length in the circumferential direction.

  Therefore, as shown in FIGS. 8 and 9, when the bracket 8 is overlapped with the flange portion 14 of the steering hole cover 7, a portion other than the stopper portion 24 in the cutout portion 23 and a protruding convex portion 26 on the cover body 13 side are provided. , The bracket 8 is rotated by a predetermined amount with respect to the flange portion 14 in the direction of preventing separation, that is, in the direction of arrow M in FIG.

  At that time, the lower end of the protruding convex portion 26 on the cover body 13 side rides on the stopper portion 24 on the bracket 8 side, and the protruding convex portion 26 on the cover main body 13 side forms the raised portion 24 a of the stopper portion 24 on the bracket 8 side. When overcoming, as shown in FIGS. 12 and 13 in addition to FIGS. 10 and 11, the stopper portion 24 on the bracket 8 side is provided between the protruding convex portion 26 on the cover body 13 side and the recess 22 on the flange portion 14 side. It is caught. At the same time, the protruding convex portion 26 on the cover body 13 side gets over the raised portion 24a of the stopper portion 24 on the bracket 8 side, so that the relative position is regulated by the engagement between the two, and the protruding portion 26 is positioned at that position. As a result, the bracket 8 can be prevented from being detached from the steering hole cover 7.

  Also in the present embodiment, the separation preventing function provided by the protruding protrusion 26 on the cover body 13 side and the stopper portion 24 on the bracket 8 side is basically the same as that of the first embodiment, Therefore, also in this embodiment, the same effect as that of the first embodiment can be obtained.

  Depending on the specifications of the product, the cover body 13 may have a double-layer structure instead of a single-layer structure, but this case is naturally included in the scope of the present invention.
