Abstract

PURPOSE:To obtain positive and sufficient reinforcement by forming through holes at a floor tunnel, at the part reinforced by a center bearing supporting bracket, and distributing a parking brake cable through these through holes. CONSTITUTION:A parking brake cable supporting bracket 17 is provided at a floor tunnel 19, at the part where a center bearing supporting bracket 18 is fitted, and a through hole 26 protruding cylindrically upward is formed at the parking brake cable supporting bracket 17. Through holes 28, 29 corresponding to the through hole 26 are further formed at the upper face part 21 of the floor tunnel 19 and the bulge part 27 of the center bearing supporting bracket 18, and a parking brake cable is inserted into these through holes. The center bearing supporting bracket 18 itself has very high strength because of the bulge part 27. The rigidity of the floor tunnel 19 is thereby heightened by the bonding of the flange parts 20, and the fitting rigidity of the parking brake cable supporting bracket 17 fitted at the floor tunnel 19 is heightened simultaneously, thus preventing the deformation around the through hole 28.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a parking brake cable wiring structure.

<Prior art> As a conventional parking brake cable wiring structure, there is a structure as shown in FIGS. 3 to 5, for example.
(Refer to Publication No.-166683).

1 is a floor tunnel of an automobile, and a parking brake handle 2 is provided on the front right side of the tunnel.

A parking brake cable support bracket 4 is provided above the top surface 3 of the floor tunnel 1, and a reinforcement 5 is provided below the top surface 3, and both are connected to the floor tunnel 1 through screw holes 30. It is attached with a port 6 and a nut '1 with the upper surface part 3 sandwiched therebetween.

And these parking brake cable support brackets 4
, the upper surface part 3 of the floor tunnel 1, and the reinforcement 5, respectively, are continuously formed with corresponding through holes 8, 9, and IO. A parking brake cable 1 extending from the parking brake handle 2 is inserted into the through holes 8, 9, and 10.
1 has been inserted. This parking brake cable 11 consists of an outer tube lla and an inner wire llb, and in response to the operation of the parking brake handle 2, only the inner wire llb moves within the outer tube lla. At this time, each of the through holes 8, 9, 10
The parking brake cable 1l contacts with a strong force corresponding to the operating force of the parking brake handle 2, but since the floor tunnel l is reinforced with the reinforcement 5, the through hole 9 of the floor tunnel 1 The surrounding area becomes difficult to deform. Although not shown, the through holes 8, 9, and IO through which the parking brake cable l1 is inserted are provided with a seal structure for ensuring watertightness.

Further, a center bearing support bracket l2 is provided in the floor tunnel l, which corresponds to a position slightly rearward of the through holes 8, 9, and 10. This center bearing support bracket l2 has an inverted hat shape in cross section and includes a flange part I3 joined to the inner surface of the floor tunnel 1 and a bulge part 14 forming a space S between it and the floor tunnel 1. Between the lower ends of the bulging portion 14 extending to the left and right sides thereof, there is a support member for the center bearing l5, < 16
has been erected.

<Problem to be Solved by the Invention> However, in such conventional technology, it is necessary to prevent the vicinity of the through hole 9 of the floor tunnel 1 from deforming due to contact with the parking brake cable 11 when operating the parking brake handle 2. Although the floor tunnel 1 was reinforced with Reinforce 5, it could not be said that this Reinforce 5 alone was necessarily sufficient for reinforcement. The provision of this reinforcement 5 was disadvantageous in terms of weight and cost.

Further, since it was necessary to provide a seal structure (not shown) in the through holes 8, 9, and 10 to ensure watertightness, this was also disadvantageous in terms of cost.

Means for Solving the Problems> In order to solve the above problems, the parking brake cable wiring structure according to the present invention has a structure in which a parking brake cable is installed in a floor tunnel.
A center bearing support bracket having an inverted hat-shaped cross section and having a flange portion joined to the inner surface of the floor tunnel and a bulge portion forming a space between the floor tunnel is provided, and the floor tunnel is provided with a center bearing support bracket having an inverted hat shape in cross section. To,
A parking brake cable support bracket is installed, and through holes for parking brake cable wiring are formed in each of the parking brake cable support bracket, the floor tunnel, and the bulge portion of the center bearing support bracket. The parking brake cable is routed through the through hole.

Function: Since the parking brake cable is routed through the floor tunnel in the area reinforced by the center bearing support bracket, the reinforcement is reliable and sufficient, and conventional reinforcement is not required.

In addition, since there is a space between the through hole formed in the bulge of the center bearing support bracket and the through holes of the floor tunnel and parking brake cable support bracket, water may enter through the through hole of the bulge. Even if this happens, there is a distance depending on the space to the through-holes of the floor tunnel and parking brake cable support bracket, so the water will not reach those through-holes and enter the interior of the vehicle. Therefore, a seal structure for ensuring watertightness, which was conventionally necessary, becomes unnecessary.

Furthermore, in the floor tunnel where the flange part is joined,
To install the parking brake cable support bracket,
The mounting rigidity of the parking brake cable support bracket is also improved compared to conventional models.

Embodiment A preferred embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Incidentally, the same reference numerals are given to the parts common to the conventional one, and redundant explanation will be omitted.

In this embodiment, the parking brake cable support bracket 17 is provided in the floor tunnel l9 in the area where the center bearing support bracket l8 is attached. That is, screw holes 22 are formed in each of the front and rear flange portions 20 of the center bearing support bracket l8 and the upper surface portion 21 of the floor tunnel 19 where they are joined, and the lower end of the screw hole 22 is provided with a screw hole 22. A weld nut 23 is attached in advance. The parking brake cable support bracket l7 has a screw hole 2 corresponding to the screw hole 22.
The parking brake cable support bracket 17 is installed by positioning the screw holes 22 and 24 in a corresponding manner and screwing the screw 25 into the weld nut 23.

The parking brake cable support bracket l7 installed in this way has a through hole 26 projecting upward in a cylindrical shape, and the upper surface 2l of the floor tunnel l9 and the bulging part 27 of the center bearing support bracket l8 have ,
Through holes 28 and 29 are formed corresponding to the through hole 26, respectively, and the parking brake cable 11 is inserted through these through holes 26, 27, and 28. The reinforcement that was previously used has been abolished as it is no longer necessary.

The center bearing support bracket 18 itself has a bulge 2
7, its own strength is very high. Therefore, by joining the flange portion 20 of this center bearing support bracket 18, the floor tunnel 1
The rigidity of the parking brake cable support bracket 9 increases, and the mounting rigidity of the parking brake cable support bracket 17 attached thereto also increases at the same time.

The bulging portion 27 of this center bearing support bracket l8
Since the parking brake cable 11 is also inserted through the through hole 29 formed in the bulge 27, the behavior of the parking brake cable 11 when the parking brake handle 2 is operated is also received by the through hole 29 of the bulge 27. The vicinity of the through hole 28 of the tunnel 19 will not be deformed.

In addition, the bulge 2 of the center bearing support bracket l8
7 and each through hole 26 of the parking brake cable support bracket 17 and floor tunnel l9,
Since there is a space S between the bulging portion 27 and the through hole 28, even if water enters through the through hole 29 of the bulging portion 27, the through hole 29
and each upper through hole 26, 28 is a distance L according to the space S.
Since the water is located far away from the vehicle interior R, the water will not enter the vehicle interior R. Therefore, watertightness is ensured and a complicated sealing structure as in the past is not required.

Effects of the Invention According to the parking brake cable routing structure according to the present invention, since the parking brake cable is routed in the floor tunnel in the portion reinforced by the center bearing support bracket, the reinforcement is reliable and sufficient. , traditional reinforcement can be abolished. Therefore, it is advantageous in terms of weight and cost.

In addition, since there is a space between the through hole formed in the bulge of the center bearing support bracket and the through holes of the floor tunnel and parking brake cable support bracket, a special seal structure is provided to ensure watertightness. Even without,
Water does not enter the vehicle interior through the through holes.

Furthermore, in the floor tunnel where the flange part is joined,
To install the parking brake cable support bracket,
The mounting rigidity of the parking brake cable support bracket is also improved compared to conventional models.
