In the conventionally proposed technology, a structure is adopted in which a speed nut is fitted to an attachment portion of the instrument panel and a hook is fastened to the speed nut.

  When a hook is attached to the instrument panel, an excessive load is applied to the instrument panel depending on the load of the suspended object, and the instrument panel may be deformed or damaged. For this reason, by extending the bracket from the hook and fixing one end of the bracket to a support stay that extends from the deck cross member and supports equipment such as an audio and air conditioner, the hook mounting portion of the hook and the instrument panel is secured. Supporting structures are considered.

  When the hook is supported on the support stay of the deck cross member via the bracket, a long bracket extending from the deck cross member to the instrument panel is required, which increases the size of the parts, leading to an increase in weight and cost. In addition, as the bracket becomes larger, the degree of freedom of component layout within the instrument panel is reduced. For this reason, there is a demand for a structure that can distribute the load applied to the hook mounting portion of the instrument panel from the hook without using a large and heavy bracket, and can suppress deformation and breakage of the instrument panel. is there.

  On the other hand, in recent years, in order to effectively use the space in the vehicle interior, vehicles have emerged that include a shift lever for performing a speed change operation on a part of the instrument panel. A shift operation mechanism such as a shift lever is assembled into a base bracket and assembled into an assembly part, and the base bracket of the shift operation mechanism assembled into an assembly part is fixed to an attachment stay of the deck cross member.

  Since the load applied to the hook 5 is supported on the shift operation mechanism 2 side, an upper limit value of the load that is allowed to be supported by the hook 5 is set in advance. In the unlikely event that the load applied to the hook 5 exceeds the allowable upper limit (when the load applied to the hook 5 is excessive), the operation function of the shift lever 3 and the function of dropping the shift lever 3 in an emergency are affected. There is a possibility that

  Therefore, when the load applied to the hook 5 becomes excessive (a predetermined value or more) between the hook bracket 13 and the base bracket 6 (hook stay 11) of the speed change operation mechanism 2, the hook bracket 13 and the base bracket 6 ( A transmission blocking part for blocking the transmission of load to the hook stay 11) is provided. That is, one end 13a of the hook bracket 13 is attached to the seat surface 12 of the hook stay 11 via the transmission blocking portion.

  Thereby, even if the load applied to the hook 5 becomes excessive, the transmission preventing portion prevents the load from being transmitted from the hook 5 to the base bracket 6 (hook stay 11), and the base bracket 6 is deformed. And the function of the speed change operation mechanism 2 is not affected.

  Based on FIGS. 3-7, the structure of the attachment part of the hook bracket 13 and the hook stay 11 is demonstrated, and a transmission prevention part is demonstrated concretely.

  FIG. 5 shows an exploded perspective view of the attaching portion of the hook stay 11 and the hook bracket 13 in FIG. 4, and FIG. 6 shows a cross-section of the attaching portion of the hook stay 11 and the hook bracket 13 in FIG. FIG. 7 shows a section taken along the line VII-VII in FIG. 3, which represents a cross section of the attachment portion of the hook stay 11 and the hook bracket 13.

  As shown in FIG. 5, the hook stay 11 is integrally extended from the base bracket 6, and the cross section seen from the longitudinal direction is such that the upper wall surface 11 a intersects the upper wall surface 11 a from both sides of the upper wall surface 11 a and the upper wall surface 11 a. It is formed in a substantially U-shape (see FIG. 5) configured by a pair of extending side wall surfaces 11b. A screw hole 23 through which the seat surface 12 to which the hook bracket 13 is fastened and the fixing screw 25 is inserted is formed at the tip of the upper wall surface 11a.

  The seat surface 12 is formed thinner than other portions of the upper wall surface 11a, and in the present embodiment, the seat surface 12 is configured as a transmission blocking portion. The side wall surface 11b of the hook stay 11 is formed such that its width gradually decreases from the base portion on the base bracket 6 side toward the tip end side. The hook bracket 13 is a long sheet metal member, and one end 13a fixed to the hook stay 11 is formed in a flat shape, and a fixing hole 24 through which a fixing screw 25 is inserted is formed.

  A speed nut 21 as a resin bush nut member is fitted to the seat surface 12 of the hook stay 11, and one end 13 a of the hook bracket 13 is fastened to the speed nut 21 by a fixing screw 25. In other words, the seat surface 12 of the hook stay 11 and the one end 13a of the hook bracket 13 are coupled together in a state where no axial force is applied by the fastening member.

  The speed nut 21 is a resin part having a U-shaped cross section, is fitted to the seat surface 12 of the hook stay 11, and the seat surface 12 is sandwiched by the speed nut 21. A nut hole 22 having a threaded portion is formed in the speed nut 21, and the speed nut 21 is fitted into the seat surface 12 of the hook stay 11, whereby the speed nut is inserted into the screw hole 23 of the seat surface 12 of the hook stay 11. 21 nut holes 22 are correspondingly positioned.

  The position of the fixing hole 24 of the one end 13a of the hook bracket 13 is aligned with the position of the nut hole 22 of the speed nut 21, and the fixing screw 25 is inserted over the nut hole 22 (screw hole 23) and the fixing hole 24. One end 13 a of the hook bracket 13 is attached to the seat surface 12 of the hook stay 11 via the speed nut 21 by screwing the fixing screw 25 into the portion. Thereby, the hook stay 11 and the hook bracket 13 are connected, and the hook 5 is supported by the hook stay 11, that is, the speed change operation mechanism 2.

  Next, the operation of the transmission blocking portion (seat surface 12) will be described.

  When the load applied to the hook 5 exceeds the allowable upper limit (when the load applied to the hook 5 exceeds a predetermined value), the load acts via the hook bracket 13 and the seat surface of the hook stay 11 passes through the fixing screw 25. The load is transmitted to the twelve screw holes 23, and the input concentrates on the screw holes 23 of the seating surface 12. In the present embodiment, the seat surface 12 is formed thinner than other portions, and when the load concentrates on the screw hole 23, the periphery of the screw hole 23 is broken by the load.

  For this reason, the fixing screw 25 is removed from the screw hole 23, and the hook bracket 13 is detached from the seat surface 12 of the hook stay 11. Therefore, even if the load applied to the hook 5 becomes excessive, it is possible to prevent the base bracket 6 from being deformed without applying an excessive load to the base bracket 6. Therefore, the function of the speed change operation mechanism 2 is not affected.

  For example, since the base bracket 6 of the speed change operation mechanism 2 is not deformed, the shift lever 3 is moved forward when an excessive impact is applied to the shift lever 3 due to an occupant colliding with the shift lever 3 in an emergency. The function of mitigating the impact force on the occupant is not impaired.

  It should be noted that the load at which the screw hole 23 of the seating surface 12 serving as the transmission blocking portion is broken is appropriately controlled by adjusting the thickness of the seating surface 12 and the position of the screw hole 23, for example, the distance from the tip of the hook stay 11. can do.

  In addition, as a configuration of the transmission blocking portion described above, the screw hole 23 of the seating surface 12 of the hook stay 11 or the fixing hole 24 of the hook bracket 13 can be a U-shaped groove opening at the end. It is. With such a structure, when an excessive load is applied from the hook 5 to the hook bracket 13, the fixing screw 25 is provided from the screw hole 23 of the seat surface 12 of the hook stay 11 or the fixing hole 24 of the hook bracket 13. Since it is easily removed, the hook stay 11 and the hook bracket 13 can be more securely disconnected, and the transmission of the load can be prevented. Further, the hook stay 11 can be prevented from being deformed or damaged.

  As described above, the mounting structure of the vehicle hook according to the present invention supports the load applied to the hook 5 on the speed change operation mechanism 2 side, so that the hook mounting hole of the instrument panel 1 is used without using a large and heavy bracket. It becomes possible to suppress the damage and deformation | transformation of the instrument panel 1 by disperse | distributing the load added to 1a periphery.

  Further, by providing a transmission blocking portion between the hook stay 11 and the hook bracket 13 of the base bracket 6, an excessive load transmission from the hook 5 to the base bracket 6 (hook stay 11) is blocked. Therefore, the base bracket 6 can be prevented from being deformed by the load transmitted from the hook 5, and the function of the speed change operation mechanism 2 is not affected.

  In this embodiment, the transmission blocking portion is configured such that the screw hole 23 of the seat surface 12 of the hook stay 11 is broken and the fixing screw 25 is removed from the screw hole 23. It is good also as a structure which provides a weak part in the boundary part with this part, and the seat surface 12 is cut | disconnected from the hook stay 11 in a weak part, or deform | transforms.
