Abstract
The invention discloses a connecting structure of a rear bumper and a rear apron board of an automobile. The connecting structure comprises the rear bumper (1) which is connected with the rear apron board (2) through a bolt (3). The invention is characterized in that a pull rivet nut (4) is arranged on the rear apron board (2), the bolt (3) penetrates through the rear bumper (1) and the pull rivet nut (4) and then is connected with the rear bumper (1) and the rear apron board (2), and fluid sealant is filled between the threaded fit surface of the bolt (3) and the pull rivet nut (4). The connecting structure can effectively prevent rain from flowing into a trunk from the connecting bolt holes of the rear bumper and the rear apron board and has the advantages that the bolt hole can be produced conveniently and fast, the efficiency is high, and the appearance is attractive.
Description
Technical field
The present invention relates to automobile rear bumper, more particularly, relate to the connection structure of automobile rear bumper and back skirtboard.
Background technology
At present, automobile rear bumper is that back skirtboard is positioned at the baggage container rear portion by bolt and back skirtboard bonded assembly, be the formation baggage container surround one of part.Rear bumper is connected with the back skirtboard, be that rear bumper and back skirtboard are provided with the bolt via hole, the position relative with the bolt via hole, the back side at the back skirtboard is welded with project-welding nut, rear bumper is overlapped on the skirtboard of back, bolt from top to bottom successively through rear bumper, after skirtboard and project-welding nut, with rear bumper with the back skirtboard be connected.Because gapped between the via hole of bolt and rear bumper and back skirtboard, rainwater very easily enters the inner chamber of back skirtboard by the via hole of bolt, causes the baggage container infiltration, even seeping phenomenon occurs.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of automobile rear bumper with the back skirtboard connection structure, it can prevent rainwater from rear bumper with the back skirtboard the tie bolt orifice flow go into baggage container.
Technical scheme of the present invention is as follows: the connection structure of a kind of automobile rear bumper and back skirtboard, comprise rear bumper, rear bumper is connected with the back skirtboard by bolt, it is characterized in that: on the skirtboard of described back, the staking nut is installed, after described bolt passes described rear bumper and staking nut, rear bumper is connected with the back skirtboard.
The project-welding nut that the present invention uses tradition on the skirtboard of back changes the staking nut into, the staking nut comprises the circle cover that is provided with tapped bore, one end of circle cover is provided with first ring surface, be provided with axial teeth groove at the circle cover near on the external cylindrical surface of ring surface, after the staking nut is installed on the skirtboard of back, the length overall of staking nut shortens, the face of cylinder at its circle cover teeth groove position is compressed and is deformed into second ring surface, back skirtboard is sandwiched between first ring surface and second ring surface of staking nut, the bottom outlet that is used to install the staking nut on the back skirtboard is sealed by two ring surfaces, rainwater can't through the staking nut and after enter baggage container between the skirtboard, effectively realize the waterproof purpose.And in traditional connection structure, the welded nut on the back skirtboard needs to carry out the clear silk of screw thread after welding, could assemble smoothly, and the staking nut is easy for installation, quick, does not need the clear silk of screw thread, and the efficient height is simultaneously also more attractive in appearance.
For making waterproof effect better, stop rainwater to enter from thread pitch, between the screw thread fit face of described bolt and staking nut, be filled with sealant.
As preferably, described sealant is a butyl rubber, and butyl rubber has good vapor seal, can keep permanent adhesive in wide temperature range.
As preferably, described staking nut is a stainless steel, is difficult for getting rusty.
The invention has the beneficial effects as follows: can prevent effectively that rainwater from going into baggage container from the rear bumper and the tie bolt orifice flow of back skirtboard, and screw is easy to prepare, quick, and the production efficiency height is also more attractive in appearance.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, the present invention is the connection structure of a kind of automobile rear bumper and back skirtboard, mainly is made up of rear bumper 1, back skirtboard 2, bolt 3 and staking nut 4.Wherein, on the skirtboard 2 of back, be provided with bottom outlet 21, staking nut 4 is through in the bottom outlet 21 of back skirtboard 2, first ring surface 41 of staking nut 4 heads and installation become second ring surface 42 of back formation bottom outlet 21 are clamped sealing, thereby staking nut 4 is fixed on the skirtboard 2 of back, also the gap between staking nut 4 and the back skirtboard 2 is sealed simultaneously, rainwater can't enter baggage container through between the two.After bolt 3 passes rear bumper 1 and staking nut 4, rear bumper 1 is connected with back skirtboard 2, between the screw thread fit face of bolt 3 and staking nut 4, is filled with sealant, the sealant butyl rubber, thus make rainwater also can't enter baggage container from thread pitch.For avoiding staking nut 4 to get rusty, the staking nut 4 in the present embodiment is a stainless steel.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
