Abstract
The invention relates to an automobile rear suspension mounting assembly structure. A side wall rear upper inner cover, a rear wheel outer bump and a C column reinforcing part form a closed section structure, section lines of the side wall rear upper inner cover, the rear wheel outer bump and the C column reinforcing part form a triangular closed section structure, the side wall rear upper inner cover and the rear wheel outer bump are separately arranged at a position of a shock absorber mounting plate, the side wall rear upper inner cover, the shock absorber mounting plate and the rear wheel outer bump form a three-layer lap joint structure, the C column reinforcing part and the rear wheel outer bump form a closed section structure, the shock absorber mounting plate and a rear wheel inner bump form another closed section structure, and the two closed section structures are connected together to form a four-section closed structure. An extending angle of the rear wheel outer bump is more gentle, punching manufacturability is better, and cost is reduced; the Y-direction size of the shock absorber mounting plate is reduced, rigidity of parts is improved, and force transitivity is better; and the overall dimensions of the total parts are reduced, utilization rate of materials is increased, and cost is lowered.
Description
Technical field
The present invention relates to a kind of automotive body structure, be specifically related to a kind of rear overhang installation assembly structure.
Background technology
In existing common economy car; The rear overhang mounting structure is general, and shown in Fig. 5-6, it comprises; Go up inside panel 31, glove edges of boards section stay bearing plate liner plate 41, glove edges of boards section stay bearing plate 51, the outer bulge 61 of trailing wheel, C post reinforcement 71 behind bulge 11 in the trailing wheel, bumper adapter plate 21, the gusset; Its concrete connection structure is a prior art, and its defective is: when went on the bad road of jolting of being everlasting when automobile (1), the rear overhang bumper passed to the bumper adapter plate to power.Going up inside panel behind this adapter plate and the gusset is two-layer overlap joint, and the bulge local section becomes the L type outside the trailing wheel, and Y is big to size for the bumper adapter plate.Total is unfavorable for the transmission of load, causes rear overhang attachment point rigidity low, is out of shape greatlyyer, even the point of attachment solder joint comes off, and influences car load and turns to handling stability, influences occupant's personal traveling comfort.(2) trailing wheel external drum wrap molding difficulty, manufacturability is poor; Last inside panel and bumper adapter plate oad are big behind the gusset, and at the bottom of the stock utilization, cost is higher.
Summary of the invention
The invention reside in defective, a kind of new automobile rear overhang installation assembly structure is provided, can better transmit the load that the rear overhang bumper transmits, make the rear drum bag assembly structure that undesirable deformation not take place, improve car load and turn to handling stability, traveling comfort to prior art; And can practice thrift mould development expense and parts cost in a large number.
The technical scheme that the present invention adopts:
A kind of rear overhang installation assembly structure; It goes up inside panel, glove edges of boards section stay bearing plate liner plate, glove edges of boards section stay bearing plate, the outer bulge of trailing wheel, C post reinforcement after comprising bulge in the trailing wheel, bumper adapter plate, gusset; It is characterized in that: upward inside panel, the outer bulge of trailing wheel, C post reinforcement have formed the closed section structure behind the gusset; Triangular closed cross section structure of section line composition of three is gone up outer bulge piecemeal to the bumper adapter plate place of inside panel and trailing wheel behind the gusset, go up inside panel and bumper adapter plate, three layers of bridging arrangement of the outer bulge formation of trailing wheel behind the gusset; The outer bulge of C post reinforcement and trailing wheel; Bulge forms the closed section structure respectively in bumper adapter plate and the trailing wheel, and two closed sections link together, and form one four cross section closing structure.
Above-mentioned bumper adapter plate, glove edges of boards section stay bearing plate and glove edges of boards section stay bearing plate liner plate form case type structures.
The section line of going up inside panel behind the above-mentioned gusset is near vertical.
The technique effect that the present invention obtains:
(1) the outer bulge 6 of trailing wheel is drawn angle and is relaxed more, and punching process character is better, and cost reduces;
(2) Y of bumper adapter plate 2 reduces to size, and the rigidity of part improves, and the transitivity of power is better; The oad of whole part reduces, and stock utilization improves, and cost reduces;
(3) upward inside panel 3 is simple in structure behind the gusset, and punching process character is good.Spare part outside measurement reduces, and stock utilization improves, and cost reduces.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present invention is done further explanation.
Referring to Fig. 1-4; A kind of rear overhang installation assembly structure; It goes up inside panel 3, glove edges of boards section stay bearing plate liner plate 4, glove edges of boards section stay bearing plate 5, the outer bulge 6 of trailing wheel, C post reinforcement 7 after comprising bulge 1 in the trailing wheel, bumper adapter plate 2, gusset, and upward inside panel 3, the outer bulge 6 of trailing wheel, C post reinforcement 7 have formed closed section structure (as shown in Figure 3) behind the gusset.Three's section line near linear is formed a triangle, forms leg-of-mutton closed section structure.This structural mechanical property is good, can better bear from rear overhang bumper load impacting.And the section line of going up inside panel 3 behind the gusset is favourable to loading transfer to Z near vertically.
With going up inside panel 3 and outer bulge 6 piecemeals to bumper adapter plate 2 places (like the solder joint place of Fig. 3, three-way junction) of trailing wheel behind the gusset, go up inside panel 3 behind the gusset and form three layers of bridging arrangement through spot welding with bumper adapter plate 2, the outer bulge 6 of trailing wheel; This three layers of bridging arrangement since thickness greater than two-layer overlap joint, so intensity is better.The Y of bumper adapter plate 2 reduces to size, also improved Y to rigidity.
C post reinforcement 7 and the outer bulge 6 of trailing wheel, bumper adapter plate 2 forms the closed section structure respectively with the interior bulge 1 of trailing wheel, and so latter two closed section links together through four layers of weldering again, forms a bigger closed section structure (as shown in Figure 4).Can be with the load that transmits from bumper adapter plate 2, disperse to be delivered to C post reinforcement 7, glove edges of boards section stay bearing plate 5 well, above the glove edges of boards section stay bearing plate liner plate 4.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the intent of the present invention also comprises these changes and is out of shape interior.
