Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to the structure of a jack-up point of a vehicle such as an automobile, and more particularly to one used for a vehicle equipped with a sil spoiler.
[0002]
[Problems to be solved by the invention]
As shown in FIG. 3, the structure of the conventional jack-up point includes an upper vertical surface 2a joined to a vertical side surface 1a of the sill inner 1A and a lower sill inner 1A of the side sill 1 which is a longitudinal skeleton member of the vehicle. A standard bracket 2 provided with a continuous jack contact surface 2b and a lower vertical surface 2c that is superposed and joined to the lower end 1b of the sill inner 1A to position the jack 4 in the vehicle width direction is provided. What set the jack point is known.
[0003]
On the other hand, there is known a vehicle in which a sill spoiler 5 is attached as a rectifying member to the lower part on the outer side of the side sill 1 in order to enhance the rectifying effect of the wind underfloor flow during traveling of the vehicle and improve the running stability. Yes.
[0004]
In this way, in the case of a vehicle with the sill spoiler 5 attached, the lower part of the sill spoiler 5 wraps around below the side sill 1 as compared with a standard vehicle without the sill spoiler. The jack point set by 2 cannot be jacked up by applying a tool such as the jack 4 or the like.
[0005]
Therefore, as shown by the phantom lines in FIG. 3, a part corresponding to the jack point of the sill spoiler 5 is partially provided with a notch in the lower part of the sill spoiler 5, or a removable or openable lid is provided. A tool such as the jack 4 reaches the jack point during the work.
[0006]
However, according to this structure, there is a problem in that the appearance of the appearance is impaired by the notch portion and the lid provided in the sill spoiler.
[0007]
In addition, as shown in FIG. 4, as a structure that does not impair the appearance of the appearance in this way, a bracket 2 ′ for a vehicle equipped with a sill spoiler that extends the jack point to the lower part of the sill spoiler 5 in advance instead of the standard bracket 2. A structure provided with a can be considered.
[0008]
However, according to this structure, the bracket 2 ′ forming the jack point portion is dedicated to the silo spoiler-equipped vehicle and is not shared with the standard vehicle, resulting in high production costs and disadvantageous costs. .
[0009]
Furthermore, since a dedicated bracket 2 'must be attached instead of the standard bracket 2 in the vehicle assembly process in advance, it is determined whether the vehicle is a standard vehicle or a sill spoiler-equipped vehicle during assembly. It was impossible to use this structure when trying to install a sil spoiler on a completed standard vehicle.
[0010]
Therefore, the present invention can set the installation of the silpoiler later on the completed standard vehicle, and even if the silpoiler is installed, it will affect the appearance and production cost. The structure which can set a jack point is provided.
[0011]
[Means for Solving the Problems]
According to claim 1, in a structure in which a bracket is joined to a sill inner of a side sill that is a vehicle longitudinal skeleton member and a jack point is provided, an upper vertical surface joined to a vertical side surface of the sill inner at a lower portion of the sill inner Standard jack point is set by providing a standard bracket with a jack abutting surface connected to it and a lower vertical surface that is superposed and joined to the lower end of the sill inner to position the jack in the vehicle width direction. At the same time, the brackets for extension are provided on the upper vertical surface of the standard bracket and the lower surface of the sill outer, and the bracket is extended between the upper vertical surface of the standard bracket and the lower surface of the sill outer, It is characterized in that it can be set below the vehicle from the standard jack point.
[0012]
In claim 2, the bracket according to claim 1 includes a second upper vertical surface fastened and fixed to an upper vertical surface of a standard bracket provided on the sill inner, a second jack abutting surface continuous therewith, and An inner bracket having a second lower vertical surface for positioning the jack in the vehicle width direction, a third lower vertical surface overlapped with the second lower vertical surface of the inner bracket, and a third continuous upper surface 3 an outer bracket having an upper vertical surface and a sill outer attachment surface attached to the sill outer lower surface.
[0013]
【The invention's effect】
According to the first aspect of the present invention, the upper vertical surface joined to the vertical side surface of the sill inner, the jack abutting surface connected thereto, and the lower end of the sill inner are overlapped and joined to the lower part of the sill inner, and the vehicle width direction of the jack A standard bracket with a lower vertical surface for positioning is provided to set a standard jack point, and an additional bracket fixing means is provided on the upper vertical surface of the standard bracket and the lower surface of the sill outer. Since the brackets can be extended across the upper vertical surface of these standard brackets and the lower surface of the sill outer, the jack point can be set below the standard jack point, so that the sill spoiler can be used for completed standard vehicles. In addition to making it possible to set the sill spoiler, jacks and other tools interfere even if the sill spoiler is installed. The jack point can be set at any position, so there is no need to provide a notch or a detachable or openable lid on the part corresponding to the jack point of the sill spoiler, and the jack point can be set without affecting the appearance. can do.
[0014]
In addition, the standard bracket can be shared by both standard and silspoiler-equipped brackets, and the bracket and fixing means for expansion can be shared both when the silo spoiler is mounted on the completed standard car and when the silo spoiler is assembled. This is also advantageous in terms of production cost.
[0015]
According to claim 2, in addition to the effect of claim 1, the bracket includes a second upper vertical surface fastened and fixed to an upper vertical surface of a standard bracket provided on the sill inner, and a second jack contact surface continuous therewith. And an inner bracket having a second lower vertical surface for positioning the jack in the vehicle width direction, a third lower vertical surface superimposed on the second lower vertical surface of the inner bracket, and above Since the outer bracket has a third upper vertical surface continuous with the outer bracket and a sill outer mounting surface attached to the lower surface of the sill outer, the vertical direction input is mainly transmitted to the standard bracket via the inner bracket for support. In addition, the left and right direction input is transmitted through the outer bracket to the sill outer so that the side sill, which is a vehicle skeleton member, can reliably support the input. It can be.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
