The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention. It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.
It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present invention by way of illustration, and only the components related to the present invention are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.
As shown in fig. 1 to 3, the rear body assembly and the rocker beam connecting structure provided by the embodiment of the application comprises a rocker beam 2 and a rear body assembly 1 which are connected with each other.
The rear integrated assembly 1 at least comprises the rear floor panel 110 and the rear longitudinal beam 120 which are integrally formed, and of course, besides the rear floor panel 110 and the rear longitudinal beam 120, the rear integrated assembly 1 can also comprise structural members of other lower vehicle bodies, such as reinforcing cross beams, the rear integrated assembly 1 integrates the functions of most sheet metal parts of the rear floor, the lower vehicle body is structurally integrated into a whole, and the rear integrated assembly 1 greatly reduces the development quantity of structural parts by integrating various parts together, and simplifies the process flow.
As shown in fig. 1 to 3, the rear longitudinal beam 120 includes a first outer vertical plate 121, a first inner vertical plate 122 and a first top plate 123, wherein the first outer vertical plate 121, the first inner vertical plate 122 and the first top plate 123 form an inverted U-shaped structure, and the first outer vertical plate 121, the first inner vertical plate 122 and the first top plate 123 form a cavity 124 with a downward opening. The rear body assembly 1 is preferably an integrally formed cast aluminum member formed by a high pressure casting process, and the cavity 124 is used for controlling the casting deformation of the rear side member 120, improving the collision performance and enhancing the connection strength with the sill beam 2. In addition, the cavity 124 can reduce the weight of the rear integrated assembly 1 while guaranteeing the strength and rigidity of the rear integrated assembly 1, and the cavity 124 is opened downwards, so that the problems of effusion and the like can be effectively avoided.
The rear body assembly 1 is not integrally connected with the threshold beam 2, and the rear longitudinal beam 120 of the rear body assembly 1 can only form the cavity 124 through downward core pulling due to the limitation of the mold structures such as the core pulling direction of the high-pressure casting mold cavity, the boundary between the left mold core and the right mold core, and the like. However, with this structure, since the in-vehicle connection space is blocked, the first outer riser 121 of the cavity 124 cannot be directly provided with a screw hole connected to the threshold beam 2, and if the first inner riser 122 or other structures of the rear body assembly 1 are considered to be provided with a notch to provide an operation space, the cavity 124 is not connected continuously, resulting in poor collision strength. Based on the above, a plurality of nut mounting holes 125 which are communicated with the cavity 124 are formed in the first outer vertical plate 121, a rivet nut 3 is arranged in the nut mounting holes 125, the threshold beam 2 comprises a second outer vertical plate 210 and a second inner vertical plate 220, the second inner vertical plate 220 is attached to the first outer vertical plate 121, a plurality of first bolt mounting holes 230 which are opposite to the rivet nut 3 are formed in the second inner vertical plate 220, and a plurality of through holes 240 which are opposite to the first bolt mounting holes 230 are formed in the second outer vertical plate 210; the rear integrated assembly and threshold beam connecting structure further comprises a plurality of first bolts 4, and the first bolts 4 penetrate through the first bolt mounting holes 230 from one side of the threshold beam 2 and then are locked with the rivet nuts 3.
Through the scheme of the embodiment, the outer side surface of the first outer vertical plate 121 and the inner side surface of the second inner vertical plate 220 are used as the assembling surfaces of the rear integrated assembly 1 and the door sill beam 2, the outer side surface of the first outer vertical plate 121 and the inner side surface of the second inner vertical plate 220 are in fit with each other, the rivet nut 3 can be placed into the nut mounting hole 125 inwards at the outer side of the first outer vertical plate 121 before the first outer vertical plate 121 is fit with the second inner vertical plate 220, after the first outer vertical plate 121 and the second inner vertical plate 220 are fit with each other, the through holes 240 on the second outer vertical plate 210 can be used as the mounting channels of the first bolts 4 and the bolt mounting sleeves 9, the first bolts 4 are mounted in the direction from the outer side to the inner side, the first bolts 4 are locked with the rivet nut 3, and the rivet nut 3 stretches into the cavity to form a rivet piece to be tightly attached to the first outer vertical plate 121, so that the first outer vertical plate 121 and the second inner vertical plate 220 are locked together, and the door sill beam 2 is connected at the position of the cavity.
In some embodiments, the sill beam 2 is an extruded aluminum profile, in order to improve the supporting strength of the structure of the sill beam 2, a rib plate is further arranged inside the sill beam 2 to connect the outer wall of the sill beam 2, the rib plate may include a transverse rib plate 260 and a longitudinal rib plate 250, at least one longitudinal rib plate 250 is arranged on the longitudinal rib plate 250, the cavity inside the sill beam 2 may be divided into a plurality of small cavities by the transverse rib plate 260 and the longitudinal rib plate 250, for example, as shown in fig. 3, the cross section of the passing sill beam 2 can see that the inside of the sill beam 2 is provided with a first cavity 270 and a second cavity 280 opposite to the nut mounting hole 125, and due to the arrangement of the longitudinal rib plate 250, the passing of the first bolt 4 and the bolt mounting sleeve 9 is blocked, so that the through hole 240 is uniformly arranged on the longitudinal rib plate 250, that is matched with the rivet nut 3 after the bolt passes through the through hole 240 on the second outer vertical plate 210, the through hole 240 on the longitudinal rib plate 250 and the first bolt mounting hole 230 on the second inner vertical plate 220 at a time in fig. 3.
In some embodiments, the first bolts 4 are disposed at intervals along the extending direction of the threshold beam 2, so as to improve the connection strength between the threshold beam 2 and the rear body assembly 1, and the specific number of the first bolts 4 may be specifically selected according to the use requirement, for example, as shown in fig. 1 and 2, and the first bolts 4 are disposed at intervals along the extending direction of the threshold beam 2.

Since the lower end of the first outer riser 121 is lower than the lower end of the first inner riser 122, the bolting with the sill beam 2 can be achieved at the portion of the first outer riser 121 lower than the first inner riser 122, and the second bolt 5 can be penetrated in the inside-out direction during the connection. Preferably, a plurality of second bolts 5 are disposed at intervals along the extending direction of the threshold beam 2, so as to improve the connection strength between the threshold beam 2 and the rear body assembly 1, and the specific number of the second bolts 5 may be specifically selected according to the use requirement, for example, as shown in fig. 1 and 2, and 4 second bolts 5 are disposed at intervals along the extending direction of the threshold beam 2. In the case where the second bolts 5 are provided in plural at intervals along the extending direction of the rocker beam 2, the number of the second bolt mounting holes 126 should be kept identical to the number of the first bolts 4.

The sill beam 2 is an extrusion, and is divided into chambers of different sizes by the transverse rib plates 260 and the longitudinal rib plates 250, for example, a third chamber 290 in fig. 3, the nut plate 6 is located in the third chamber 290, the cross section of the third chamber 290 in the extending direction of the sill beam 2, that is, the front-rear direction of the vehicle body is uniform, and both ends are open, so that the nut plate 6 can be plugged into the third chamber 290 along the extending direction of the sill beam 2 by using a tool fixture, and is connected to the second inner riser 220 by using the blind rivet 7. The first and second nuts achieve double-row up and down bolting between the first outer riser 121 and the second inner riser 220, improving the strength of connection between the rear body assembly 1 and the rocker beam 2.
In some embodiments, as shown in fig. 2 and 3, the rear longitudinal beam 120 is further provided with a fixing wing plate 127, the fixing wing plate 127 and the first top plate 123 are respectively located at two sides of the first outer vertical plate 121, and the fixing wing plate 127 is fixed above the threshold beam 2 by a screw 8. Specifically, the fixed wing plate 127 and the first outer vertical plate 121 form an L-shaped structure, the first outer vertical plate 121 is in fit with the second inner vertical plate 220 of the threshold beam 2, and the fixed wing plate 127 is in fit with the top of the threshold beam 2, so that the rear integrated assembly 1 and the threshold beam 2 are directly connected in both horizontal and vertical directions, and the connection strength and stability between the two are improved.
In some embodiments, the screw 8 is a trephine screw. The flow drill screw melts the base material by using the heat generated by the high-speed rotation of the flow drill screw, and the pressure is increased to punch through the base material and make threads on the base material, so that the fixed wing plate 127 and the threshold beam 2 are fixed together, the flow drill screw is suitable for a single-sided connection process, particularly suitable for the connection of a tubular closed structure such as the threshold beam 2, has no waste chip in the working process, and does not need additional processing procedures.
