Abstract
The invention discloses an automobile door sill, which comprises an inner door sill plate and an outer door sill plate. The sections of the inner door and the outer door are groove-shaped. The inner door sill plate and the outer door sill plate are relatively and fixedly connected to form a cavity structure the section of which is mouth-shaped. The automobile door sill is characterized in that the upper lapping edge of the inner door sill plate is in butt welding connection with the upper lapping edge of the outer door sill plate, and the lower lapping edge of the inner door sill plate is in butt welding connection with the lower lapping edge of the outer door sill plate; a cambered turnover edge on the lower lapping edge of the outer door sill plate covers a gap between the lower lapping edge of the outer door sill plate and the lower lapping edge of the inner door sill plate; and two end parts of the lower lapping edge of the inner door sill plate are provided with a protrusion respectively, and two drain holes are formed between the protrusions and the lower lapping edge of the outer door sill plate. Proper strength and rigidity of the door sill are ensured, and the anticorrosion capability of the door sill is effectively improved; and the automobile door sill is favorable for spraying sealant at the bottom of the door sill, avoids difficulty in manual operation and waste of the sealant and reduces the cost.
Description
Technical field
The invention belongs to automobile body components, be specifically related to a kind of automobile door sill.
Background technology
In recent years, along with the fast development of automobile industry, automobile design more becomes to becoming more meticulous.Threshold is the vitals in the car body, for structural strength, rigidity and the collision performance of car load important effect is arranged.In order to improve antiseptic power, guarantee intensity, the rigidity of threshold, threshold generally uses high strength galvanized steel plate to make, and cost is higher.Aspect doorsill structure, the design of existing threshold bottom is perfect inadequately, threshold inner panel, the butt welding of threshold outside plate usually, and its section is " mouth " font; The bottom landing edge of threshold outside plate and threshold inner panel is measure-alike, the threshold integrated bottom is shaped as a straight flange, there is not the application hole, painting effect is bad, and when the spraying sealant, sealant can not can not be given full play to the sealing function of sealant for the threshold bottom well attached on the car body.Vehicle ' is under different road environments, and the vehicle bottom often suffers abominable situations such as stone hits, muddy water, and environment for use is very abominable, is short of for antiseptic power.Therefore, necessary at the configuration aspects optimal design.
Summary of the invention
The purpose of this invention is to provide a kind of automobile door sill, it has higher strength and stiffness, and good seal performance, can improve threshold bottom corrosion resistance, can also improve coating process, reduces material cost.
A kind of automobile door sill of the present invention comprises that section is the threshold inner panel and the threshold outside plate of groove, and threshold inner panel and threshold outside plate relative fixed are connected to form the cavity body structure that section is " mouth " font, make it have higher strength and stiffness, it is characterized in that:
Be respectively equipped with landing edge and following landing edge at the bottom and upper segment of threshold inner panel; Be respectively equipped with landing edge and following landing edge at the bottom and upper segment of threshold outside plate, the following landing edge of this threshold outside plate is longer slightly than the following landing edge of threshold inner panel, and the edge designs of the following landing edge of threshold outside plate has inside arc flange;
The last landing edge of threshold inner panel is connected with the last landing edge butt welding of threshold outside plate, and the following landing edge of threshold inner panel is connected with the following landing edge butt welding of threshold outside plate; Arc flange on the following landing edge of threshold outside plate shelters under the threshold inner panel slit between the landing edge under the landing edge and threshold outside plate.
Described a kind of automobile door sill is characterized in that: a projection has been designed at the both ends at the following landing edge of described threshold inner panel respectively, forms two drain gutters between the following landing edge of these two projectioies and threshold outside plate.
The present invention compares with prior art and has the following advantages:
(1) turnup structure of threshold outside plate itself can alleviate the corrosion of the threshold inner panel that the reason owing to silt causes, and guarantees the strength and stiffness of threshold; The groove structure that the inside and outside plate of threshold forms is beneficial to the spraying of threshold base sealing, has avoided the difficulty of workman's operation and the waste of sealant;
(2) on former and later two positions of the inside and outside plate of threshold, form the drain gutter of two section approximate trapezoid, help the application draining by the inside and outside plate of threshold;
(3) make, to form technology simple, realize easily;
(4) effectively raise the antiseptic power of threshold, what guaranteed threshold should have strength and stiffness, and therefore, the inside and outside panel material of threshold can be cancelled zinc-plated, cost-cutting.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to a kind of automobile door sill shown in Figure 1, comprise that section is the threshold inner panel 1 and the threshold outside plate 2 of groove, threshold inner panel and threshold outside plate relative fixed are connected to form the cavity body structure that section is " mouth " font, therefore have higher strength and stiffness; Be respectively equipped with landing edge 1-1 and following landing edge 1-2 at the bottom and upper segment of threshold inner panel 1; Be respectively equipped with landing edge 2-1 and following landing edge 2-2 at the bottom and upper segment of threshold outside plate 2, the following landing edge of this threshold outside plate 2 is longer slightly than the following landing edge of threshold inner panel 1, and the edge designs of the following landing edge of threshold outside plate has inside arc flange 5;
The last landing edge 1-1 of threshold inner panel 1 is connected with the last landing edge 2-1 butt welding of threshold outside plate 2, and the following landing edge 1-2 of threshold inner panel 1 is connected with the following landing edge 2-2 butt welding of threshold outside plate 2; Arc flange 5 on the following landing edge of threshold outside plate shelters under the threshold inner panel slit between the landing edge under the landing edge and threshold outside plate; Prevent in silt, the rainwater entry threshold,, in addition, also help the operation with the workman of adhering to of application sealant, avoid the waste of sealant to delay the corrosion rate of threshold inner panel.
Both ends at the following landing edge 1-2 of described threshold inner panel are provided with a projection 6 respectively, form two drain gutters between the following landing edge 2-2 of these two projectioies and threshold outside plate.The drain gutter of the section approximate trapezoid that forms is used for the application draining, improves the manufacturability of application, and actv. improves the resistance to corrosion of threshold.
