[0087] The truck interior simulation model of the embodiment of the present application has a ceiling including a middle ceiling guard plate, side ceiling guard plates and a rear ceiling guard plate. The middle ceiling guard plate, side ceiling guard plates and rear ceiling guard plate are all fixed to the inner top side of the model frame by bolts, and the middle ceiling guard plate, side ceiling guard plates and rear ceiling guard plate are connected by an interlocking structure.

[0088] The above-mentioned truck interior simulation model can effectively reduce costs, improve model strength, thermal stability, simulation and accuracy, and is easy to assemble as a whole, ensuring the accuracy of styling effect verification results.

[0089] Specifically, the exterior decoration assembly includes a top cover 2 , a front wall 3 , an A-pillar 4 , an upper cross beam of a front windshield 5 , a black area of ​​a front windshield 6 , a door panel 7 , and a door opening 8 .

[0090] Among them, the top cover has two structures, such as Figure 2 , Figures 5 to 9 As shown, the first type reflects part of the real roof profile, and the second type only reflects the simplified profile. The first type is mainly for flat-top trucks. Considering the cost and aesthetics of the model, it reflects the front half of the roof. The rear boundary of the roof is cut 40±10mm backward in the X direction according to the rear boundary of the door. The thickness of the roof material is 5mm, and reinforcing ribs are arranged on the back. The roof (interior) is longer than the roof (exterior) in the X direction. The front end of the roof (exterior) is screwed and fixed to the A-pillar frame, and the rear end of the roof (interior) is screwed and fixed to the ceiling frame. The space between the roof (exterior) and the ceiling (interior) is less than 10mm after removing the thickness of the materials of the two. There is no space for additional metal frame arrangement, so the two adopt an interlocking structure. For those with low requirements for exterior decoration, bolt holes can be opened in the roof, and threaded sleeves are preset on the back of the roof. The bolts are locked from the roof side to the ceiling side. The opening of the roof can be beautified by using the same color plugging cover; for those with high requirements for exterior decoration, the roof profile must not be destroyed, and the roof and ceiling are interlocked with buckles. As shown Figure 3 As shown, the second type is mainly for high-top trucks. The roof area of ​​high-top trucks is large. Considering the production cost, the roof usually only reflects a simplified surface. The upper, left, right and rear surfaces are made of 5mm thick ABS flat cover plates. The front surface is designed as a single curved surface with an offset relationship with the curvature of the upper edge of the front windshield. Because the flatness of the curved surface formed by the bending of the ABS plate is difficult to control, a whole piece of PU material is used, and the thickness of the thinnest part is not less than 30mm. Bolt holes are designed, and a positioning surface is designed on the back. Bolts are locked to the elevated box frame from the outside to the inside. The top cover opening can be beautified with a plug cover of the same color.

[0091] Among them, Fig.10 As shown, the front enclosure only reflects the lower edge of the windshield, and the profile is cut with a horizontal plane 150±30mm downward from the lowest point of the windshield in the Z direction. The bottom is designed with a 20mm thick plane, and the outer contour is aligned with the front end of the instrument panel frame. The ABS cover on the upper surface of the instrument panel frame is replaced to improve the flatness. The front is designed with mounting holes, and the back is designed with a positioning surface. It is bolted to the instrument panel frame from top to bottom. The top cover opening can be beautified with a plug cover of the same color. At the same time, the front windshield black area overlap surface is reserved according to the outer surface of the front windshield offset 2mm inward or the original data sheet metal surface. The upper boundary of the overlap surface is based on the Z-direction drop of 20mm from the front edge of the instrument panel.

[0092] Among them, Figures 11 to 13As shown, the A-pillar needs to support the top cover and ceiling, so a metal frame is designed. The cross-sectional size of the metal frame is 30mm×50mm. The upper end of the metal frame is designed with a Z-direction mounting plane and three mounting holes, which are connected to the ceiling side frame. The lower end of the metal frame is designed with a Z-direction mounting plane and three mounting holes, which are connected to the instrument panel frame. The outer side of the metal frame is designed with φ20 positioning holes and bolt holes. The A-pillar outer plate is fixed to the outer side of the frame by bolts. The bolts are locked from the inside to the outside. The back nut position is designed with a sink to prevent the nut from protruding and affecting the installation of the A-pillar inner guard plate. The A-pillar outer guard plate is designed as a solid structure to ensure the rigidity of the parts. The inner side of the metal frame is designed with φ25.5 deep 5mm and φ20.5 deep 5.5mm stepped holes. A strong magnet with a thickness of φ20 and a thickness of 5mm is buried in the φ20.5 deep 5.5. The φ25.5 deep 5mm positioning hole cooperates with the φ25 positioning column of the A-pillar inner guard plate. The positioning column is pre-embedded with a magnet of the same size as that in the A-pillar frame. The A-pillar inner guard plate is fixed to the A-pillar frame by magnetic attraction. The A-pillar inner guard plate is designed as an ABS thin-walled structure with a material thickness of 5mm. Reinforcement ribs are arranged on the back to ensure the rigidity of the parts. After the A-pillar inner and outer guard plates are fixed to the A-pillar metal frame, the installation structure is not exposed. The inner side of the A-pillar outer guard plate is offset 2mm inward from the outer surface of the front windshield or the original data sheet metal surface reserves the front windshield black area overlap surface, and the inner boundary of the overlap surface shall not exceed the A-pillar inner guard plate.

[0093] Among them, Fig.14 and Fig.15 As shown, the upper crossbeam of the windshield only reflects the upper edge of the windshield. The profile is cut from the horizontal plane 30±10mm upward in the Z direction at the upper edge of the front windshield. The front windshield black area overlap surface is reserved by offsetting 2mm inward from the outer surface of the front windshield or the sheet metal surface of the original data. The lower boundary of the overlap surface shall not exceed the front edge of the elevated box. The mounting point is designed on the back, and it is screwed and fixed to the back of the interior elevated box from top to bottom in the Z direction.

[0094] Among them, Fig.16 As shown, the black area of ​​the windshield is a hyperbolic surface with a thickness of 2 mm. The inner boundary can refer to the gradient black dot boundary of the windshield of a real car, or it can be designed by yourself to ensure that the splicing position of the interior and exterior can be completely covered.

[0095] Among them, Figures 17 to 22As shown, the door panel is divided into two parts, the upper and lower parts. The upper part reflects the area around the window frame, the outer sheet metal of the door, the upper part of the inner sheet metal of the door, the water cut, and the rubber strip, which are combined into one entity without disassembly. The lower boundary is cut with a plane or a folded surface with an average distance of about 150mm from the lower edge of the side window. The specific design is based on the shape of the lower edge of the side window to ensure the aesthetics. The outer sheet metal surface of the door is designed with a Y-direction mounting hole, and the back is designed with a positioning surface. It is screwed and fixed to the door panel frame from the outside to the inside. The opening can be beautified with a plug cover of the same color. The front and rear of the inner sheet metal surface of the door are designed with two X-direction mounting holes respectively, which are locked to the inner door guard plate with bolts to play a reinforcing role. The lower part reflects the lower half of the inner sheet metal of the door. When the door cover plate is designed to be closer to the outside in the Y direction, there is a gap between the inner sheet metal of the door and the door cover plate. At this time, the inner sheet metal surface of the door is extended in the Y direction to intersect with the door cover plate. The overlapping relationship between the door inner sheet metal and the door inner guard plate is that the door inner guard plate presses the door inner sheet metal. The door inner sheet metal can be bolted to the door inner guard plate body from the back through the overlapping surface, and can also be directly bolted to the door frame through the overlapping surface.

[0096] Among them, the door opening of the mass-produced car is part of the side panel sheet metal. Since the interior simulation model does not need to reflect the complete side panel sheet metal, the door opening can simplify the process, such as Figure 23 to Figure 29As shown, the door opening is divided into 5 sections, and non-metallic materials are CNC or 3D printed to reduce production costs. The upper section 83 of the door opening is integrated with the A-pillar outer guard plate. The upper boundary of the door opening is consistent with the upper crossbeam of the windshield introduced above, the rear boundary is aligned with the rear boundary of the A-pillar inner guard plate, the lower boundary is aligned with the upper boundary of the door upper hinge, and the bolts are locked to the A-pillar frame. The front boundary of the lower section 84 of the door opening is aligned with the front boundary of the door outer panel, and the lower boundary is aligned with the lower boundary of the door lower hinge. It is fixed to the dashboard frame with bolts, and the hinge position is opened to avoid air. The lower section 82 of the door opening is designed as a solid structure or a thin-walled part. The lower boundary of the lower section is cut 100mm downward in the Z direction of the interior floor, and the rear boundary is cut 40±10mm backward in the X direction according to the rear boundary of the door outer panel. The upper boundary of the rear end is aligned with the lower boundary of the side inner guard plate, and the Y-direction and Z-direction mounting holes are reserved, and the bolts are locked to the interior floor body. The rear section 85 of the door opening is designed as a whole with the body of the inner guard plate of the side wall, and the front and back sides are processed and formed. The top boundary of the rear section of the door opening is aligned with the top boundary of the inner guard plate of the side wall. It should be noted that this part is assembled from the inside to the outside, and the assembly direction interferes with some structures. The loose piece 851 needs to be removed to avoid air. Taking heavy trucks as an example, the interfering parts include the front bracket of the upper berth, the installation point on the rear armrest, and the door hinge. The loose piece is a 3mm thick thin-walled part. After all the parts in this area are assembled, the three loose pieces are finally glued and fixed to the door opening, and the gaps are repaired with atomic putty, and sprayed as a whole to improve the aesthetics. The upper section 81 of the door opening is designed as a solid structure to ensure the rigidity of the parts. The mounting point is designed on the back. According to the specific surrounding environment, the parts are assembled to the adapter leading out of the ceiling side frame, ceiling side guard plate or other positions, and the connection is stable. The door opening needs to be clamped with a sealing strip, which has a relatively high strength. In mass-produced vehicles, the strip is clamped to the sheet metal surface, and the sheet metal has sufficient strength. In the simulation model, in order to simulate the deformation of the door opening parts, the rigidity of the five sections of the door opening must be guaranteed. It should be noted that the thickness of the rubber strip joint edge is usually 3-5mm, and the substitute wood material is prone to cracking when the thickness is less than 5mm. Therefore, if a section of the door opening is made of substitute wood, the rubber strip joint edge needs to be disassembled, processed with ABS, and bonded and fixed together.

[0097] The electrical assembly includes an electronic control component and an air supply component, wherein the electronic control component mainly includes a power supply, a controller, a wiring harness, etc. Due to the length limit of some wiring harnesses (mainly video signal cables), the electronic control component is usually installed in the dashboard frame and fixed to the wooden board or adapter with bolts. When maintenance is required, the front ABS cover plate can be removed or the front ABS cover plate can be opened. The wiring harness of the remote electrical parts is arranged between the interior components and the cover plate, and can be fixed to the frame with cable ties. In order to ensure the flexibility of the model display, the model power supply usually uses a battery. Regarding the air supply component, the commercial vehicle interior simulation model mainly needs to use compressed air for the seats. The compressed air pipe can be passed through the floor under the seat, arranged along the model frame to the tail of the model, and a joint is reserved. When the model is displayed, an external air source can be connected.

[0098] The interior assembly of the truck interior simulation model includes several main parts: dashboard, steering wheel, door panels, floor, overhead box, side panels, rear panels, ceiling, seats, berths, and auxiliary instrument panel.

[0099] like Fig.30 As shown, the components of the dashboard can be divided into a dashboard body 10, a cover 17, an instrument assembly, a control panel assembly, a screen, an air outlet, buttons and knobs, decorative parts, etc. The following mainly introduces the dashboard body and the cover.

[0100] like Fig.31 and Fig.32 As shown, the dashboard body is the basic component of the dashboard assembly, and the remaining parts or assemblies are installed on the dashboard body. Therefore, the dashboard body needs to have sufficient strength and precision. It is designed as a solid wood structure and is formed by five-axis integrated processing. The dashboard body and the dashboard frame adopt a three-sided positioning form. The back of the dashboard body is pre-embedded with a threaded sleeve, which is locked together with the dashboard frame from the X direction and the Z direction respectively. The installation points of other dashboard components are designed on the dashboard body, mainly including three categories: the first category is the magnetic suction installation point, which is used for most dashboard components to be installed and fixed in this way; the second category is the screw installation point, which is used to fix components that are easy to deform or have force requirements; the third category is the adhesive installation point, which has the simplest structure and is used to fix non-important components such as side air outlets and lower air outlets that do not need to be repeatedly disassembled and adjusted. It should be noted that, except for the local installation positioning points, the dashboard body and the later assembled components have a clearance of no less than 5mm to avoid interference during the subsequent assembly process.

[0101] like Fig.33 and Fig.34As shown, the instrument panel cover 17 is a plastic part in mass-produced vehicles. The surface is usually decorated with textures and stitches. It is provided with a foam embedded area 171 and a sewing thread slot 172. The surface decoration is achieved through two processes: metal mold injection molding and fabric coating. Usually only one model is produced. The cost of opening a metal mold is too high, so fabric coating can only be used. In order to ensure the manufacturing accuracy of the instrument panel, the ideal situation is that all covers are integrally formed with the instrument panel body, but the gap between different covers is usually 0.5mm-1mm. The gap is too small to be coated and trimmed, so it is necessary to disassemble the parts. Based on this premise, the principle of disassembling at least every other piece can be followed, and as many covers as possible can be retained and processed integrally with the instrument body to ensure its processing accuracy, while ensuring that adjacent covers must be separable. Small-sized covering parts (defined as the longest side ≤ 1000mm) can be designed as thin-walled parts with a thickness of 3mm, and can be fixed to the instrument panel body by magnetic attraction; large-sized covering parts (defined as the longest side > 1000mm), mainly involving covering parts on the instrument panel, are designed as solid parts or thin-walled parts with a thickness of not less than 5mm, and must be fixed to the instrument panel body by all screws or partial screws and partial magnets to reduce deformation caused by insufficient magnetic attraction.

[0102] The complexity of the design of the covering lies in the design of the overcut surface of the covering. For different types of covering fabrics, the structural data is offset according to the standards of simulated leather grain (without sewing thread) overcut 0.5mm, simulated leather grain (with sewing thread) overcut 0.8mm, PVC overcut 0.8mm, microfiber overcut 1mm, genuine leather overcut 1.2mm, and fabric overcut 1.5mm, to ensure that the outer surface after covering is basically consistent with the shape data surface.

[0103] Common types of sewing threads include double stitches, single stitches without drop, and single stitches with drop. For double sewing threads, the slot width is the distance between the double visible stitches plus 4-6mm, and the slot depth is the thickness of the single-layer fabric plus 0.5mm; for single stitches without drop, the slot width is the distance between the visible and hidden stitches plus 2-3mm, and the slot depth is the thickness of the double-layer fabric plus 0.5mm; for single stitches with drop, no slotting is required, and the step is designed to be 2-3mm away from the visible stitch, and the step height is based on CAS data. For soft touch requirements, choose 2mm or 3mm thick foam and embed it in the cover before the covering fabric. The covering needs to be overcut to the same depth as the foam thickness on the basis of the thickness required for the overcut fabric covering. It should be noted that the R corner of the cover cannot be covered with foam, otherwise the covering fabric will compress the foam when it is tightened, resulting in an increase in the R angle and a significant change in the shape. Therefore, within 3mm from the root of the fillet, only the offset amount of the covering fabric is overcut, and the depth of the preset sponge is not overcut.

[0104] The door panel includes the door inner panel body, covering parts, door armrests, button knobs, speaker covers, decorative parts, etc. The following mainly introduces the door inner panel body, covering parts and door armrests.

[0105] The door inner panel body is the basic component of the door inner panel assembly. The other parts or assemblies are installed on the door inner panel body. Therefore, the door inner panel body needs to have sufficient strength and precision. It is designed as a solid wood structure and is processed and formed in one piece. The door inner panel body and the door panel frame adopt a one-side two-pin positioning form. The back of the door inner panel body is pre-embedded with a threaded sleeve, which is locked together with the door panel frame from the Y direction. The installation points of other door inner panel components are designed on the door inner panel body. The installation point design method is the same as the instrument panel introduced above.

[0106] The structural design method of the door panel cover is the same as that of the instrument panel described above. It should be noted that the map pocket needs to be back-mounted. The map pocket is designed as a thin-walled part with a thickness of 3-5mm, with reinforcing ribs arranged on the back and mounting claws arranged around with a spacing of no more than 400mm. It is bolted to the door inner panel body from the back. The door armrest cannot be fixed to the door inner panel body because it needs to be stressed separately. It needs to be directly screwed to the door frame.

[0107] like Fig.35 and Fig.36 As shown, the floor includes a floor body, a lower baffle plate for the berth, and a threshold molding. The floor body is the basic component of the floor assembly. It is not a serious part of the styling focus. Considering the cost of model making, it is designed as a solid part made of PU material, and the anti-slip pattern can be removed. A 20mm thick wooden board is laid on the area corresponding to the floor body on the floor frame 18, which is milled to 18mm, and the upper surface of the wooden board fits the lower surface of the floor body. The floor body, wooden board, and floor frame are bonded as a whole, or a threaded sleeve is embedded on the back of the floor body and locked with the floor frame by Z-direction bolts, and positioned with two pins on one side. Installation points for other components are designed on the floor body. The installation point design method is the same as the dashboard introduced above. It should be noted that the PU material has poor wear resistance and will lose precision after repeated disassembly and assembly. Therefore, each installation point needs to be designed with a separate insert embedded in the floor body. The material is usually substitute wood, ABS or metal.

[0108] Seats and handrails for getting on and off the vehicle need to be fixed to the floor frame through an adapter frame because they are subject to greater forces. The floor body just above the adapter frame is removed to facilitate the adjustment of the adapter frame.

[0109] The lower baffle of the berth is designed as a solid part made of PU material, with a pre-embedded threaded sleeve on the back, and is locked with the lower berth frame by X-axis bolts.

[0110] like Fig.37 and Fig.38As shown, the side panel includes a side panel body, a storage bucket, a rear armrest for getting on and off the vehicle, and an upper berth bracket. The side panel body is the basic component of the side panel assembly, which is designed as a solid wood structure and is processed and formed in one piece. The rear section of the door opening is designed as an integral part of the side panel. The side panel body and the side panel frame adopt a three-sided positioning form, and a threaded sleeve is embedded on the back of the side panel body, which is locked together with the side panel frame from the Y direction. The side panel body is designed with installation points for other rear panel parts, and the installation point design method is the same as the instrument panel introduced above. The rear armrest for getting on and off the vehicle and the upper berth bracket cannot be fixed to the side panel body because they need to be subjected to force separately, and need to be directly screwed and fixed to the side panel frame.

[0111] like Fig.39 and Fig.40 As shown, the rear enclosure includes the rear enclosure body, the upper berth hinge, and the rear curtain slide rail. The rear enclosure body is the basic component of the rear enclosure assembly, which is designed as a solid wood-substitute structure and is formed in one piece. The rear enclosure body and the rear enclosure frame are positioned on three sides, and a threaded sleeve is embedded on the back of the rear enclosure body, which is locked together with the rear enclosure frame from the X direction. The rear enclosure body is designed with mounting points for other rear enclosure parts, and the mounting point design method is the same as the instrument panel introduced above. The upper berth hinge cannot be fixed to the side enclosure body because it needs to be stressed separately, and needs to be directly screwed and fixed to the door frame. The rear enclosure sealing plate is not a real exterior rear enclosure. There is a gap between the interior rear window and the rear enclosure sealing plate. An X-direction stretching surface is made according to the boundary of the rear window for shielding and beautification.

[0112] like Fig.41 As shown, the elevated box includes an elevated box body, a storage box, a storage bucket, a control panel, a sunshade, and a sun visor. The elevated box body is the basic component of the elevated box assembly, and the remaining parts or assemblies are installed on the elevated box body. In order to ensure the assembly processability, the elevated box body should not be too heavy. It is designed as a 5mm thick thin-walled part with reinforcing ribs on the back. It can be formed by carbon fiber or fiberglass lamination, or by ABS CNC machining. The elevated box body and the elevated box frame adopt a two-sided one-pin positioning form. The back of the elevated box body is pre-embedded with a threaded sleeve, which is locked together with the elevated box frame from the X and Z directions. The installation points of other components of the elevated box are designed on the elevated box body, and the installation point design method is the same as the instrument panel introduced above.

[0113] like Fig.42 and Fig.43As shown, the ceiling includes a middle ceiling guard plate, side ceiling guard plates, rear ceiling guard plates, side ceiling decorative plates, skylight decorative covers, and ceiling lighting. The middle ceiling guard plate, side ceiling guard plates, and rear ceiling guard plates are the basic components of the ceiling assembly, and the remaining parts or assemblies are installed on the ceiling guard plates. To ensure assembly processability, the elevated box body should not be too heavy and is designed as a 5mm thick thin-walled part with reinforcing ribs on the back. It can be formed by carbon fiber or fiberglass lamination, or by ABS CNC machining. Only one side is retained between each guard plate and the ceiling frame to improve assembly convenience. A threaded sleeve is embedded on the back of each guard plate and locked to the ceiling frame from the back. The ceiling guard plates are designed with installation points for other ceiling components, and the installation point design method is the same as the instrument panel introduced above.

[0114] Because the ceiling panels are thin-walled and easily deformed, in order to ensure the gap surface difference between the panels, a simple interlocking structure is designed on the back of the junction of the ceiling panels, with a matching gap of 0.5mm. The concave surface of the interlocking structure is located on the first-assembled component, and the convex surface of the interlocking structure is located on the later-assembled component. Under the premise of having a certain positioning function, the convenience of assembly is guaranteed.

[0115] like Fig.44 As shown in the figure, the structure of the seat foam is similar to that of mass-produced seats. It should be noted that the model seat has a much higher styling requirement than mass-produced seats, and high-density sponge is required to ensure the consistency of the styling. In order to ensure both styling and a certain degree of comfort, the model seat foam is designed in different areas. The main stress-bearing areas of the seat cushion and backrest with simple surfaces are designed with low-density foam, and other areas are designed with high-density foam.

[0116] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0117] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
