Each connecting rod corresponds to one of the reference surfaces, each connecting rod is arranged at a first reference position of the reference surface, and a plurality of second reference positions are uniformly distributed along the length direction of each connecting rod. Each fastener assembly 130 is mounted to one of a plurality of second reference locations on one of the plurality of tie bars, the fastener assembly 130 being for securing the trim panel to its corresponding tie bar.

By selecting an appropriate datum plane, it can be determined that the plurality of fastener components 130 mounted on the datum plane are all adjacent to the interior trim panel; the tie bar can be brought substantially close to the mounting hole in the interior panel by mounting the tie bar at an appropriate first reference position; further, by mounting the fastening member 130 at an appropriate second reference position on the tie bar, it is possible to further approach the mounting hole on the interior panel. With this arrangement, the plurality of fastener assemblies 130 can simulate a real body-in-white installation environment.

It is easy to understand that when the specifications of the body-in-white required to be simulated are different, the real installation environment of the body-in-white of the required specifications can be simulated by adjusting the first reference position where the connecting rod is installed and the second reference position where the fastening assembly 130 is installed, so that the occupied space of the body-in-white is reduced, the transportation cost of the body-in-white is reduced, and the layout area of a workshop is also reduced.

The multifunctional simulated body jig 100 is used to simulate a body in white, and in detail, the multifunctional simulated body jig 100 is used to simulate the positions of a plurality of mounting holes related to the mounting of an interior panel on the body in white.

In the description of the present application, "body-in-white" refers to a vehicle body structural member and panel weld assembly, including front wings, doors, hoods, trunk lids, but excluding unpainted vehicle bodies for accessories and trim.

In the prior art, the interior trim panel is generally assembled by overlapping a plurality of glass fiber composite panels. Whether can assemble in the automobile body and whether two the fine composite sheets of lapped glass each other can the overlap joint standard in order to verify independent fine composite sheet of glass, need try to install two fine composite sheets of lapped glass each other in white automobile body, assemble the debugging and detect. And the multi-functional simulation automobile body assembly jig 100 in this application embodiment can simulate white automobile body, if two glass fiber composite boards of overlap joint each other can accord with the overlap joint standard when installing in multi-functional simulation automobile body assembly jig 100, then it also can accord with the overlap joint standard when real assembly.

Further, the multifunctional simulated body mount 100 in the embodiment of the present application is capable of simulating various specifications of body-in-white. For interior trim panel manufacturers, on one hand, the interior trim panel manufacturers can occupy less laboratory space, and the stacking space of body-in-white with various specifications is saved, so that the planning area of the whole workshop is reduced. On the other hand, the multifunctional simulated vehicle body assembly jig 100 has a weight smaller than that of a body-in-white, and is easy to move.

Referring to fig. 9, in the embodiment of the present application, two glass fiber composite boards overlapped with each other are a ceiling board 200 and a rear cover board 300 respectively disposed at the back, and the rear cover board 300 and the ceiling board 200 are overlapped with each other. Specifically, the ceiling panel 200 includes a first side 210 and a second side 220, the rear cover panel 300 includes a third side 330 and a fourth side 340, the first side 210 of the ceiling panel 200 is used to overlap a ceiling panel (not shown) disposed in front, and the second side 220 overlaps the third side 330 of the rear cover panel 300. Referring to fig. 8, the rear cover plate 300 further includes a first surface 310 and a second surface 320, and in an actual installation process, the first surface 310 is used for adhering to an inner wall surface of a vehicle body; the second surface 320 is a functional surface for exposure to the vehicle body interior space.

In other embodiments, the two glass fiber composite panels overlapped with each other may be the ceiling panel 200 arranged at the back and the ceiling panel arranged at the front.

The frame 110 includes a plurality of reference surfaces, each reference surface corresponding to a mounting surface of the body-in-white.

The multifunctional simulated vehicle body assembly jig 100 in the embodiment of the present application is used to detect whether the mutually overlapped ceiling plate 200 and the rear cover plate 300 meet the overlapping standard. Therefore, the number of reference surfaces is set to two, which are adjacent first reference surface 160 and second reference surface 170, respectively.

Referring to FIG. 5, the first datum surface 160 is substantially horizontal for positioning the main portion of the ceiling board 200; the second reference surface 170 is substantially vertical for positioning the main body portion of the rear cover plate 300. As will be readily appreciated, the first reference surface 160 is used to simulate the approximate position of the roof of the body in white and the second reference surface 170 is used to simulate the approximate position of the rear panel of the body in white.

Among them, in the embodiment of the present application, since the third side 330 of the rear cover plate 300 is close to the first reference surface 160, the third side 330 is mounted to a connection rod disposed on the first reference surface 160, i.e., a third connection rod 123 described below.

Preferably, the frame 110 is a six-sided cubic frame, the first reference surface 160 is a top surface of the six-sided cubic frame, and the second reference surface 170 is a rear side surface of the six-sided cubic frame. As can be easily understood, the arrangement of the frame 110 as a six-sided cubic frame not only provides the frame 110 with better stability, but also is low in cost, easy to calculate, and light in weight, and can better simulate a body in white.

Referring to fig. 1, in some embodiments of the present application, the frame 110 includes a first frame 111 and a second frame 112 spaced apart in the y-direction, the first frame 111 and the second frame 112 are connected by four connecting strips 113, and each connecting strip 113 extends in the y-direction and connects corners of the first frame 111 and the second frame 112 to form a six-sided cubic frame.

The first block 111 and the second block 112 are constructed identically.

Taking the first box 111 as an example, the first box 111 is formed by splicing four long tubes. Two adjacent long tubes are detachably connected at the corners.

Referring to fig. 2 and 5, as an example, the first frame 111 includes a first tube 1111, a second tube 1112, a third tube 1113 and a fourth tube 1114 connected end to end in sequence, and two adjacent long tubes are perpendicular to each other and are fastened together by a triangular bracket 1115 in cooperation with a screw.

In the z-direction, the first reference surface 160 includes a plurality of first mounting hole groups 115, each first mounting hole group 115 corresponding to a first reference position, and each first reference position corresponding to a position for mounting the connecting rod.

As will be readily appreciated, this arrangement can reduce the number of arrangements of the connecting rods in the first reference plane 160, simplifying the construction of the multifunctional simulated vehicle body mount 100.

In some embodiments of the present application, the four long tubes of the first frame 111 are octagonal tubes, and a plurality of mounting holes are uniformly distributed on each prism surface along the length direction of the prism surface.

Referring to fig. 3, taking the fourth tube 1114 as an example, one surface of the fourth tube facing the outside of the frame 110 is the mounting surface 116, and two adjacent mounting holes in the plurality of mounting holes on the mounting surface 116 form a first hole pair 114.

Similarly, a second hole pair corresponding to the first hole pair 114 is also provided in the second block 112, the first hole pair 114 and the second hole pair having the same z-coordinate and together forming a first set of mounting holes 115, one set of mounting holes 115 corresponding to a first reference position.

As will be readily appreciated, when a connecting rod is mounted at a first reference position, its length extends in the y-direction; by selecting different first reference positions, the connecting rods have different z-direction heights.

Referring to fig. 1, the connecting rod group 120 includes a plurality of connecting rods, each connecting rod is mounted on the frame 110, each connecting rod corresponds to a reference surface, each connecting rod is mounted at a first reference position of the reference surface, and a plurality of second reference positions are uniformly distributed along the length direction of each connecting rod.

It will be readily appreciated that this arrangement increases the strength of the fourth 124 and fifth 125 connecting rods and prevents them from deforming under load.

Referring to fig. 6, taking the first connecting rod 121 mounted on the second reference surface 170 as an example, a plurality of third hole pairs 1211 are disposed at intervals along the length direction of the first connecting rod 121, each third hole pair 1211 includes two mounting holes arranged at intervals along the width direction of the first connecting rod 121, two adjacent third hole pairs 1211 form a second mounting hole group 1212, one second mounting hole group 1212 corresponds to one second reference position, and one second reference position is used for mounting one fastening assembly 130.

As will be readily understood, the plurality of mounting holes in the second mounting hole group 1212 belonging to the same group correspond one-to-one to the plurality of second slots 142 in the fastening assembly 130, which will be described below, and one fastening assembly 130 can be mounted to one second reference position of the first connecting rod 121 using the screw and nut engagement.

The fastener assembly 130 is mounted to the tie bar at a second reference location, and the plurality of fastener assemblies 130 cooperate to secure the trim panel to the set of tie bars 120.

For convenience of description, referring to fig. 4, in the embodiment of the present application, a specific configuration of the fastening assembly 130 is illustrated by taking as an example a first through hole 350 of the back cover 300 and the fastening assembly 130 corresponding thereto.

Referring to fig. 7, the connecting block 140 includes a first slot 141 and a plurality of second slots 142 formed along the thickness thereof. The first slot 141 is used for the fastener 150 to pass through, and the second slot 142 is used for the screw member (not shown) to cooperate to mount the connection block 140 at the second reference position of the first connection rod 121.

The second slots 142 are provided in two rows, and the two rows of the second slots 142 are arranged at intervals along a direction perpendicular to the extending direction thereof (i.e., the z direction). It is easy to understand that the number of the second slots 142 is four, and four second slots 142 correspond to four mounting holes in the second mounting hole group 1212 one by one.

Preferably, the first slot 141 and the second slot 142 are both waist-shaped holes, and the extending direction of the first slot 141 is perpendicular to the extending direction of the second slot 142.

As an example, referring to fig. 1 and 7, the first slot 141 extends along the z-direction, and the second slot 142 extends along the y-direction.

It is easy to understand that the second slot 142 is arranged as a waist hole extending along the y direction based on a second reference position, and the mounting position of the connection block 140 can be further finely adjusted in the y direction based on the second reference position, so that the positional accuracy of the fastener 150 is improved to be closer to the real mounting hole position of the vehicle body.

The first slot 141 is used for the fastener 150 to pass through, so as to fixedly connect the back cover plate 300 with the connecting block 140.

It is easily understood that the first slot 141 is a waist hole extending in the z-direction based on the position of the connection block 140 relative to the frame 110, and the position of the fastener 150 can be further adjusted in the z-direction based on the connection block 140 to be closer to the real vehicle body installation hole.

Further, an opening 143 is disposed at one end of the first slot 141 in the extending direction, and a locking hole 1431 is disposed on the opening 143. The fastener 150 can be clamped by both side walls of the first slot 141 by using a locking member (not shown) through the locking hole 1431 to lock the opening 143, thereby fixing the installation position of the fastener 150 on the junction block 140.

The head 1522 is attached to the second end 1524, and the outer diameter of the head 1522 is greater than the width of the first slot 141 of the sleeve, thereby preventing the threaded sleeve 152 from being pulled out of the first slot 141.

It will be readily appreciated that the position of the threaded sleeve 152 is closest to the mounting hole on the real vehicle corresponding to the first through hole 350. By adjusting the depth of the screw 151 screwed into the threaded sleeve 152, the rear cover plate 300 can be appropriately pressed.

The bolt 151 includes a bolt head 1511 and a bolt tip 1512, the bolt tip 1512 being threaded into the first end 1523 of the threaded sleeve 152.

The positioning hole sleeve 153 is used to plug the mounting hole of the back cover plate 300 to prevent the back cover plate 300 from loosening.

As an example form, the positioning boss 153 is a straight sleeve; as another example, the locating hole sleeve 153 may also be a tapered pin, the large end of which is adjacent to the threaded sleeve 152 and the small end of which passes through a mounting hole in the cover plate 300.

In some embodiments of the present application, bolt 151 is of M6 gauge, and locating boss 153 has an inner diameter of 6.2mm and an outer diameter including 8mm, 10mm, 12mm gauge. The bolt 151 penetrates into the positioning hole sleeve 153, and the outer wall of the positioning hole sleeve 153 is approximately attached to the inner peripheral wall of the mounting hole of the rear cover plate 300.
