Abstract
The utility model provides an inner supporting mechanism of automobile doorsills, which belongs to the technical field of automobile parts and solves the problems of extremely weak strength and poor compression resistance of an existing automobile doorsill connecting plate. The inner supporting mechanism of automobile doorsills comprises a floor board beam, a doorsill reinforcing plate and an inner supporting frame, the U-shaped inner supporting frame is arranged between the floor board beam and the doorsill reinforcing plate, one end, with an opening, of the inner supporting frame faces the doorsill reinforcing plate and is in overlap joint with the doorsill reinforcing plate, and the other end of the inner supporting frame facing the floor board beam is in overlap joint with the floor board beam. The inner supporting mechanism has the advantages of reasonable design, simple structure, high mechanical strength, fine safety performance and the like.
Description
Technical field
The utility model belongs to technical field of automobile parts, relates to automobile door sill, especially relates to supporting mechanism in a kind of automobile door sill.
Background technology
In order to fill the cavity in the automobile door sill, be provided with bracing frame in the automobile door sill inboard usually.Bracing frame is over against floor crossmember, the threshold resistivity when increasing automobile side impact.As shown in Figure 1, bracing frame commonly used is the U font, opening subtend floor crossmember one side.Though bracing frame also is connected by the threshold inner panel with floor crossmember, the general design-calculated intensity of threshold inner panel is very weak, does not have resistivity, is equivalent to the opening of bracing frame and the opening direct connection of floor crossmember.Therefore, area of contact is very little, and less stable is easy to both and breaks away from, thereby influences side collision power transmission effect when stressed.
In order to improve the broadside impact performance of automobile door sill, someone has invented a kind of connecting plate of automobile doorsill that welds mutually with the automobile door sill beam [application number: 200910191229.7], the box-like body of forming by four sides in a bottom surface and front, rear, left and right, the upper end-face edge of left and right two sides is curved, at least be provided with two outside flange on it, in box-like body, be provided with stay bearing plate, the base of stay bearing plate and the welding of box-like body bottom surface, left and right two sides welding of dual-side and box-like body.This connecting plate of automobile doorsill has improved the intensity of automobile door sill to a certain extent, but therefore this scheme and be not suitable for the cavity of filling in the automobile door sill still can't solve the problem that prior art exists.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, the mechanical strength height, and safety performance is good, effectively improves the interior supporting mechanism of automobile door sill of broadside impact performance.
For achieving the above object, the utility model has adopted following technical proposal: supporting mechanism in this automobile door sill, comprise floor crossmember, threshold brace panel and inner support frame, described inner support frame is arranged between floor crossmember and the threshold brace panel, it is characterized in that, described inner support frame is the U type, and the end that this inner support frame has opening overlaps mutually towards the threshold brace panel and with the threshold brace panel, and the other end of inner support frame overlaps mutually towards floor crossmember and with floor crossmember.
The overlap joint area of the inner support frame in the utility model and threshold brace panel and floor crossmember is big, and overlap joint is stable, can not break away from when stressed, thereby transmit side collision force well, significantly increases the broadside impact resistivity of automobile door sill.On the other hand, can on prior art, improve easily, need not existing structure is significantly changed, compatible good with existing auto parts and components.
In the supporting mechanism, the open end both sides of described inner support frame have turning edge of extending laterally respectively in above-mentioned automobile door sill, and described turning edge overlaps mutually with the threshold brace panel.Turn edge owing to be provided with, further improved area of contact between inner support frame and the threshold brace panel, promote working stability.
In the supporting mechanism, the opening of described inner support frame has inner small and outside big structure in above-mentioned automobile door sill.
In the supporting mechanism, described inner support frame is formed by the sheet material bending in above-mentioned automobile door sill.Because inner support frame adopts the sheet material bending to form, therefore processing get up very convenient, low cost of manufacture.
In the supporting mechanism, the cross-sectional plane of described inner support frame is isosceles trapezoid in above-mentioned automobile door sill.
In the supporting mechanism, described inner support frame equates with the width of floor crossmember with the width that floor crossmember overlaps an end mutually in above-mentioned automobile door sill.This structure helps improving connection stability, promotes the power transmission effect.
Compared with prior art, the advantage of supporting mechanism is in this automobile door sill: 1, reasonable in design, simple in structure, the overlap joint good stability can not break away from when stressed, thereby transmit side collision force well, significantly increases the broadside impact resistivity of automobile door sill.2, can on prior art, improve easily, easy accessibility, easy to implement, low cost of manufacture.
Description of drawings
Fig. 1 is the prior art constructions scheme drawing.
Fig. 2 is the structural representation that the utility model provides.
Among the figure, floor crossmember 1, threshold brace panel 2, inner support frame 3, opening 31, turn edge 32.
The specific embodiment
As shown in Figure 2, supporting mechanism comprises floor crossmember 1, threshold brace panel 2 and inner support frame 3 in this automobile door sill.Inner support frame 3 is arranged between floor crossmember 1 and the threshold brace panel 2.
In order further to improve the stability of overlap joint, the open end both sides of inner support frame 3 have respectively extend laterally turn edge 32, described turning edge 32 overlaps mutually with threshold brace panel 2.Inner support frame 3 equates with the width of floor crossmember 1 with the width that floor crossmember 1 overlaps an end mutually.
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 used floor crossmember 1, threshold brace panel 2, inner support frame 3, opening 31, the terms such as 32 that turn edge 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.
