Abstract
The utility model provides an automobile center column, belonging to the technical field of automobiles. The utility model solves the problem that electrophoretic coating treatment can not be carried out inside the traditional automobile center column. The automobile center column comprises an outer plate and an inner plate located at the inner side of the outer plate, a cavity is formed between the outer plate and the inner plate, and the inner plate is provided with a plurality of through holes communicated with the cavity. The inner plate of the automobile center column is provided with a leakage hole to ensure that an electrophoretic liquid can enter the center column through the leakage hole during electrophoretic coating process, the inside part of the center column can be fully electrophoresed, and the corrosion resistance and the strength of the automobile center column are greatly increased.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of center pillar of automobile, particularly a kind of automobile centre-pillar structure that is applicable to electrophoretic painting.
Background technology
The vehicle body of automobile has three columns, is respectively front pillar (A post), center pillar (B post), rear pillar (C post), and column also plays the effect of doorframe simultaneously except playing a supporting role.And center pillar is not only wanted the supported cart top cover; also to bear the bearing force of front and back door; when the unexpected generation of vehicle side collision, center pillar also should play the purpose of protecting the occupant to the limit in addition, thereby the strength and stiffness of center pillar require the safety performance of vehicle body is played crucial effects.
Existing centre-pillar structure as the disclosed a kind of automobile of Chinese patent (CN201494510U), it is formed by connecting by outside plate and the inner panel that is positioned at the outside plate inboard, also be installed with brace panel between described outside plate and the inner panel, increase the mechanical strength of center pillar by the brace panel that is provided with between outside plate and the inner panel.Vehicle body must be handled through electrophoretic painting when producing, to improve corrosion stability, penetrablility and the decorate properties of body material.The automobile center pillar behind the pretreatment process such as the oil flushing that at first automobile center pillar process eliminated rust, immerses and carries out the electrophoretic painting processing in the electrophoresis tank when carrying out electrophoresis coating technique.And the automobile center pillar is welded owing to a plurality of plates of employing, and electrophoresis liquid can only impregnated in middle outer surface of column, can't enter center pillar inside, causes the inner easily generation of center pillar corrosion, has influenced the intensity and the durability degree of center pillar, has shortened its service life.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of inside and can fully carry out eletrophoretic automobile center pillar.
The purpose of this utility model can realize by following technical proposal: a kind of automobile center pillar, comprise outside plate and the inner panel that is positioned at the outside plate inboard, form cavity between described outside plate and the inner panel, it is characterized in that, offer the through hole that several communicate with above-mentioned cavity on the described inner panel.
This automobile center pillar offers the through hole that communicates with internal cavities on the plate within it, thereby in the electrophoretic painting process, electrophoresis liquid can fully enter in the cavity by this through hole, all can carry out electrophoretic painting to the both sides of outside plate and inner panel and handle, and has guaranteed the corrosion stability and the mechanical strength of automobile center pillar.
In above-mentioned automobile center pillar, described number of openings is three.Be evenly distributed with three through holes on inner panel, electrophoresis liquid is flowed evenly, part each several part application degree is comparatively synchronous.
In above-mentioned automobile center pillar, also be installed with brace panel between described outside plate and the inner panel, described brace panel is offering through hole with the cooresponding position of the through hole of inner panel.Because the overall construction intensity of center pillar is had relatively high expectations, and the bulk strength that this brace panel can effectively improve the automobile center pillar is set between outside plate and inner panel, center-pillar deformation is serious when preventing that automobile from meeting accident collision.
In above-mentioned automobile center pillar, described brace panel is welded by upper reinforcing plate and lower reinforcing plate, and the thickness of described upper reinforcing plate is greater than the thickness of lower reinforcing plate.
When automobile generation side collision, be the protection occupant safety, the deformation that collision energy-absorbing produces should be positioned at the center pillar bottom as far as possible, and with the bigger living space of reservation, so the upper reinforcing plate intensity of this brace panel should be greater than lower reinforcing plate intensity.
Compared with prior art, this automobile center pillar offers liquid-leaking nozzle on the plate within it, make that electrophoresis liquid can enter center pillar inside by this liquid-leaking nozzle in the electrophoretic painting process, make center pillar inside fully carry out electrophoresis, promoted automobile center pillar in-to-in corrosion stability and intensity greatly.
Description of drawings
Fig. 1 is the sectional structure scheme drawing of this automobile center pillar.
Among the figure, 1, outside plate; 2, inner panel; 3, brace panel; 31, upper reinforcing plate; 32, lower reinforcing plate; 4, through hole; 5, through hole; 6, cavity.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this automobile center pillar comprises outside plate 1 and is positioned at the inner panel 2 of outside plate 1 inboard, form cavity 6 between outside plate 1 and the inner panel 2, also be provided with a brace panel 3 between outside plate 1 and the inner panel 2, evenly offer three through holes 4 that communicate with cavity 6 on the described inner panel 2, described brace panel 3 is provided with and the corresponding through hole 5 in inner panel 2 through holes 4 positions.
When the automobile center pillar carries out the electrophoretic painting processing, center pillar integral body is soaked in the electrophoresis liquid, three through holes 4 vertically are uniformly distributed on the inner panel 2, but electrophoresis liquid via through holes 4 and through hole 5 enter in the cavity 6, make the paint particles in the electrophoresis liquid can evenly be attached to the inside face of inner panel 2 and outside plate 1, strengthened the corrosion stability and the mechanical strength of automobile center pillar.
The brace panel 3 of this automobile center pillar is divided into upper reinforcing plate 31 and lower reinforcing plate 32; when automobile generation side collision; be the protection occupant safety; the deformation that collision energy-absorbing produces should be positioned at the center pillar bottom as far as possible; for the occupant keeps bigger living space, so upper reinforcing plate 31 thickness of this center pillar should be greater than lower reinforcing plate 32 thickness.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as outside plate 1, inner panel 2, brace panel 3, upper reinforcing plate 31, lower reinforcing plate 32, through hole 4, through hole 5, cavity 6 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
