Abstract

The invention discloses a car trunk assembly, which comprises an outer plate and an inner plate with a gel groove, and is characterized in that: a left lower sunken table, a left upper sunken table, a right upper sunken table and a right lower sunken are arranged in a registration mark plate mounting region at the lower part of the outer plate, and a left flanging and a right flanging which are in a square shape and eudipleural are arranged on the inner plate corresponding to the registration mark plate mounting region; the gel groove at the upper part of the inner plate is injected with swelling gel, and the outer plate and the inner plate are overlapped and are connected together through the swelling gel; the left flanging at the lower part of the inner plate and the left upper sunken table and the left lower sunken table at the lower part of the outer plate are welded together, and the right flanging at the lower part of the inner plate and the right upper sunken table and the right lower sunken table at the lower part of the outer plate are welded together; and the outer plate is connected with the inner plate through a buckling wrapping edge. The invention has the following advantages: the inner plate and the outer plate of the trunk are more firmly connected into a whole, thereby increasing the stiffness and strength of the trunk assembly, and being favorable for preventing the trunk assembly from shaking.

Description

A kind of car runk assembly

Technical field

The invention belongs to automobile component, be specifically related to a kind of car runk assembly.

Background technology

At present, common car runk comprises baggage container outside plate, baggage container inner panel, and outside plate is connected through fastening bound edge with inner panel.Because it is higher that baggage container opens and closes frequency of utilization, switch baggage container bump is bigger, requires runk assembly to have good rigidity and intensity.Baggage container inner and outer plates overlap joint squeezes expansion glue in the rib-pressing groove the inside again and is connected with the baggage container outside plate mainly through on the baggage container inner panel, doing the beading structure, to strengthen the rigidity and the intensity of runk assembly.But this beading adds the additional strengthening of expansion glue because the restriction of space and structure, can only be arranged in the position on the upper side of baggage container, and baggage container bottom phenomenon such as still can occur trembling because rigidity and intensity are bad causes the car load abnormal sound, and the user complains.

Summary of the invention

The purpose of this invention is to provide a kind of car runk assembly, its rigidity, intensity are good, and can prevent that chattering from taking place, and avoids causing the car load abnormal sound.

A kind of car runk assembly of the present invention; Comprise that outside plate, top are provided with the inner panel of glue groove; It is characterized in that: in the license plate installation region of outside plate bottom, be provided with heavy stand, upper left heavy stand, upper right heavy stand and bottom right heavy stand under the left side; Four heavy stands are splayed arrangement and upper left heavy stand and upper right heavy stand symmetry, and a left side is heavy stand and bottom right heavy stand symmetry down; Be provided with in the corresponding section, license plate installation region of inner panel and outside plate bottom and be " mouth " font and symmetrical left flange and right flange;

In the glue groove on inner panel top, be marked with expansion glue, outside plate and inner panel are overlapping and link together through expansion glue; The left flange of inner panel lower and the upper left heavy stand of outside plate bottom and left side heavy stand welding down, the right flange of inner panel lower and the upper right heavy stand of outside plate bottom, the welding of bottom right heavy stand; Outside plate also is connected through fastening bound edge with inner panel.

Described a kind of car runk assembly, heavy stand, upper left heavy stand, upper right heavy stand and bottom right heavy stand are circle down to be located in the license plate installation region of outside plate bottom a left side.

The present invention has kept between the baggage container inner and outer plates that existing vehicle is widely applied to through expansion glue bonded assembly structure, promptly on inner panel, establishes the glue groove, then, in the glue groove, injects and is coated with expansion glue, and baggage container inner panel and outside plate are linked together.

The present invention compared with prior art has advantage: since left flange and upper left heavy stand, a left side down heavy stand weld; Right flange and upper right heavy stand, the welding of bottom right heavy stand; So just the inside and outside plate of baggage container more firm connect into an integral body; The inside and outside plate of baggage container supports each other, has increased the rigidity and the intensity of runk assembly, helps preventing that runk assembly from trembling.

Fig. 2 is the structural representation of inner panel of the present invention.

Fig. 3 is a structural representation of the present invention.

Fig. 4 is the A-A cutaway view of Fig. 3.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

Referring to 1, Fig. 2 and a kind of car runk assembly shown in Figure 3, comprise that outside plate 9, top are provided with the inner panel 10 of glue groove 11; In the license plate installation region 5 of outside plate 9 bottoms, be provided with under the circular left side heavy stand 1, upper left heavy stand 2, upper right heavy stand 3 and 4, four heavy stands of bottom right heavy stand and be that splayed is arranged and upper left heavy stand and upper right heavy stand symmetry, left side heavy stand and bottom right heavy stand down is symmetrical; Be provided with in 5 corresponding sections, license plate installation region of inner panel 10 and outside plate bottom and be " mouth " font and symmetrical left flange 6 and right flange 7; In the glue groove 11 on inner panel 10 tops, be marked with expansion glue, outside plate and inner panel are overlapping and link together through expansion glue; The left flange 6 of inner panel 10 bottoms and the upper left heavy stand 2 of outside plate 9 bottoms and left side heavy stand 1 welding down, the right flange 7 of inner panel 10 bottoms and the upper right heavy stand 3 of outside plate 9 bottoms, 4 welding of bottom right heavy stand; Outside plate also is connected through fastening bound edge with inner panel.

So just the baggage container inner and outer plates more firm connect into an integral body, the baggage container inner and outer plates supports each other, has increased the rigidity and the intensity of runk assembly, helps preventing that runk assembly from trembling.Because bond pad locations is in the rear license plate installation region, loading onto rear license plate can block it, and unlikely solder joint exposes and influences attractive in appearance.

Claims
