Description

Technical Field

[0001] The present invention relates to the technical field of automobile cab design, in particular to a cab and an automobile. Background Art

[0002] With the increasing number of cars on the road, customers are demanding more than just performance; they are also demanding higher standards for appearance and interior. As the core operating area of ​​the vehicle, the entire cab's anti-corrosion primer and paint finish create a positive visual impact for customers and highlight its status.

[0003] During the entire primer coating process, the cab has to go through 28 liquid tanks. The pretreatment liquid and primer solution in the tank will be concentrated in the cavities and beam cavities of components such as the upper top cover. When the accumulated liquid accumulates in the beam cavity and the cavities and enters the coating line drying furnace for drying, the accumulated liquid flowing out of the cavities is dried and attached to the outer covering surfaces such as the side panels, rear panels, and front panels to form marks, which damages the quality of the electrophoretic coating on the outer covering surfaces. These marks can only be polished off with sandpaper and then the primer is sprayed again. The quality of the primer sprayed again is far lower than the original primer coating formed by the electrochemical reaction of the coating line, forming corrosion resistance defects in the cab; it will also affect the quality of the comprehensive paint coating of the cab after spraying the topcoat. The vividness, gloss, orange peel and other appearance paint properties of the paint layer will be affected and reduced, and it is also easy to form appearance defects such as color difference with the paint next to it. Therefore, it is very important to reduce the cab structure caused by primer flow marks. Summary of the Invention

[0004] Regarding the related technology, during the entire primer coating process of the cab, the paint liquid will be concentrated in the clamping cavity and beam cavity of the top cover and cannot be discharged, causing the accumulated paint liquid to flow into the subsequent paint liquid tank, or adhere to the surface of the outer covering such as the side panel, rear panel, and front panel during the drying process, leaving marks.

[0028] In order to help those skilled in the art better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] Regarding the related technology, during the entire primer coating process of the cab, the paint liquid will be concentrated in the clamping cavity and beam cavity of the top cover and cannot be discharged, causing the accumulated paint liquid to flow into the subsequent paint liquid tank, or adhere to the surface of the outer covering such as the side panel, rear panel, and front panel during the drying process, leaving marks.

[0030] In a first aspect, the present application provides a cab, which comprises: a cab body 1, an upper cover plate assembly 2 and a lower cover plate assembly 3; wherein,

[0031] An upper cover panel assembly 2 is installed on the upper part of the cab body 1; a lower cover panel assembly 3 is installed on the lower part of the cab body 1. The lower cover panel assembly 3 and the upper cover panel assembly 2 are located on the outside of the cab body 1, and the overlapping edge of the lower cover panel assembly 3 is higher than the edge of the upper cover panel assembly 2 in the height direction of the entire vehicle.

[0032] It is worth noting that the present application sets up an "overbite" structure with the upper covering part inside and the lower covering part outside, so that the residual liquid inside the outer covering part and its beam cavity during the primer coating process of the cab can only flow back into the cab along the inside of the outer covering part, and will not flow to the outside of the outer covering part of the cab, thereby effectively reducing the paint liquid adhering to the surface of the outer covering such as the side panel, rear panel, and front panel to form marks, thereby damaging the quality of the electrophoretic coating on the outer covering surface and the appearance paint film quality of the cab.

[0033] In combination with the first aspect above, the present application provides a first specific implementation method, as Figure 1 and Figure 2 As shown, the overlapping edge of the side panel outer plate 311 of the side panel 31 is located outside the side roof cover plate 211 of the side roof 21 , and the edge of the side panel outer plate 311 is higher than the edge of the side roof cover plate 211 .

[0034] It is understood that the upper cover panel assembly 2 includes the side roof 21 and the rear roof 22. The lower cover panel assembly 3 includes the side panels 31 and the rear panel 32. In this application, the side panel outer panels 311 serve as the first part of the lower cover panel assembly 3. The "overbite" structure ensures that even if liquid accumulates inside the side roof cover panel 211, gravity will prevent it from flowing from the joint between the side panel outer panels 311 and the side roof cover panel 211 to the outer side, thereby affecting subsequent manufacturing processes or affecting the appearance of the cab.

[0035] In combination with the first embodiment described above, the upper cover plate assembly 2 and the lower cover plate assembly 3 are connected at their overlapped locations by using spot welding structural adhesive.

[0036] In some specific embodiments, Figure 2 As shown, the side top cover plate 211 of the upper cover plate assembly 2 and the side outer plate 311 of the lower cover plate assembly 3 are connected by spot welding structural adhesive.

[0037] It is understandable that due to the structure of the welding clamp with multiple side panels and the fact that the welding clamp entering through the doorway cannot reach the overlapping edges of the side top cover plate 211 and the side outer panel 311, it is inconvenient to weld the overlapping parts of the side top cover plate 211 and the side outer panel 311, so spot welding structural glue is applied instead of welding.

[0038] In combination with the above specific embodiments, optionally, a sol tank 5 is provided at the joint between the upper cover plate assembly 2 and the lower cover plate assembly 3. Specifically, Figure 2 As shown, the outer surface of the side top cover plate 211 is provided with the sol groove 5 at the overlapping edge of the side outer plate 311.

[0039] It is worth noting that when using spot welding structural adhesive to achieve the bonding function, in order to ensure the bonding strength, the amount of adhesive applied must be sufficient. However, the spot welding structural adhesive is heated and cured in a drying furnace, and the colloid easily overflows from between the overlapping edges when it expands and contracts due to heat and cold. The overflowed spot welding structural adhesive forms a "scar" shape after curing, affecting the appearance of the parts. In the above embodiment, by providing a sol tank 5, the overflowed spot welding structural adhesive will preferentially flow into the sol tank 5, and after the subsequent drying furnace curing process, a smooth weld sealant will be applied to the outside to ensure the appearance of the overlapping part, while preventing rainwater flowing down the side roof from returning to the interior of the cab from the overlapping part.

[0040] In combination with the above-mentioned first aspect, the present application provides a second specific implementation method, in which a guide channel is opened on the cab body 1, one end of the guide channel is connected to the interior of the cab body 1, and the other end is connected to the gap space between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3.

[0041] It is worth noting that the gap between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3 is likely to serve as a liquid accumulation area 8 where liquid accumulates. In the above embodiment, a diversion channel is provided on the cab body 1, allowing the accumulated liquid to flow into the interior of the cab body 1 and then be discharged from the interior of the cab body 1, thereby reducing the formation of liquid accumulation and preventing the formation of a structure in which liquid is trapped between the outer cover and the beam cavity or reinforcement plate inside the cab body 1.

[0042] In combination with the above second specific implementation method, in some specific embodiments, Figure 1 、 Figure 3 and Figure 6 As shown, a drainage hole 14 is provided on the roof beam 13 of the cab body 1. Optionally, a plurality of drainage holes 14 are provided on the roof beam 13 at intervals along its length direction.

[0043] It is understood that when the cab leaves one tank and enters another, the liquid in the cavity must be completely drained, otherwise the liquid in the previous tank will flow into the next tank. Furthermore, the drainage holes 14 on the roof beam 13 serve to guide the accumulated liquid in the liquid accumulation area 8, allowing the accumulated liquid to flow from the drainage holes 14 to the interior of the cab body 1 without causing cross-flow.

[0044] In combination with the above second specific implementation method, in some specific embodiments, such as Figure 4 、 Figure 5 and Figure 7As shown, at least one drainage hole 14 is provided on the middle reinforcement plate 12 of the cab body 1 .

[0045] In some optional embodiments, in order to facilitate the positioning and overlapping of the lower cover plate assembly 3 and the upper cover plate assembly 2 in the "overbite" structure, a flange is provided at the edge of the lower cover plate assembly 3.

[0046] Furthermore, a waterproof portion is provided at the flange of the lower cover plate assembly 3. Preferably, the waterproof portion comprises a U-shaped waterproof groove 4, one end of which is connected to the rear upper crossbeam 6 of the cab body 1 and the other end extends out of the upper cover plate assembly 2.

[0047] It is understandable that rainwater often accumulates on the rear wall 32 and the rear roof 22 of the cab, and seeps into the cab through the gap between the rear wall upper crossbeam 6 and the rear lower roof cover, causing water leakage in the cab. Figure 5 As shown, one end of the rear upper cross beam 6 can be bent outward to form part of the lower cover plate assembly 3, the end of the rear upper cross beam 6 can form a lap flange, and the rear upper cross beam 6 part forms a U-shaped waterproof groove 4 structure, so that rainwater outside the cab can only be in the waterproof groove 4, and will dry naturally or be thrown out of the vehicle during driving, and will not flow into the interior of the cab.

[0048] In a second aspect, the present application provides an automobile frame structure, which includes a cab, the cab comprising: a cab body 1, an upper cover plate assembly 2 and a lower cover plate assembly 3; wherein,

[0049] An upper cover panel assembly 2 is installed on the upper part of the cab body 1; a lower cover panel assembly 3 is installed on the lower part of the cab body 1. The lower cover panel assembly 3 and the upper cover panel assembly 2 are located on the outside of the cab body 1, and the overlapping edge of the lower cover panel assembly 3 is higher than the edge of the upper cover panel assembly 2 in the height direction of the entire vehicle.

[0050] It is worth noting that the present application sets up an "overbite" structure with the upper covering part inside and the lower covering part outside, so that the residual liquid inside the outer covering part and its beam cavity during the primer coating process of the cab can only flow back into the cab along the inside of the outer covering part, and will not flow to the outside of the outer covering part of the cab, thereby effectively reducing the paint liquid adhering to the surface of the outer covering such as the side panel, rear panel, and front panel to form marks, thereby damaging the quality of the electrophoretic coating on the outer covering surface and the appearance paint film quality of the cab.

[0051] In combination with the first aspect above, the present application provides a first specific implementation method, as Figure 1 and Figure 2As shown, the overlapping edge of the side panel outer plate 311 of the side panel 31 is located outside the side roof cover plate 211 of the side roof 21 , and the edge of the side panel outer plate 311 is higher than the edge of the side roof cover plate 211 .

[0052] It is understood that the upper cover panel assembly 2 includes the side roof 21 and the rear roof 22. The lower cover panel assembly 3 includes the side panels 31 and the rear panel 32. In this application, the side panel outer panels 311 serve as the first part of the lower cover panel assembly 3. The "overbite" structure ensures that even if liquid accumulates inside the side roof cover panel 211, gravity will prevent it from flowing from the joint between the side panel outer panels 311 and the side roof cover panel 211 to the outer side, thereby affecting subsequent manufacturing processes or affecting the appearance of the cab.

[0053] In combination with the first embodiment described above, the upper cover plate assembly 2 and the lower cover plate assembly 3 are connected at their overlapped locations by using spot welding structural adhesive.

[0054] In some specific embodiments, Figure 2 As shown, the side top cover plate 211 of the upper cover plate assembly 2 and the side outer plate 311 of the lower cover plate assembly 3 are connected by spot welding structural adhesive.

[0055] It is understandable that due to the structure of multiple side panels and the inability of the welding clamp entering through the door opening to reach the overlapping edges of the side top cover plate 211 and the side outer panel 311, it is inconvenient to weld the overlapping parts of the side top cover plate 211 and the side outer panel 311, so spot welding structural glue is applied instead of welding.

[0056] In combination with the above specific embodiments, optionally, a sol tank 5 is provided at the joint between the upper cover plate assembly 2 and the lower cover plate assembly 3. Specifically, Figure 2 As shown, the outer surface of the side top cover plate 211 is provided with the sol groove 5 at the overlapping edge of the side outer plate 311.

[0057] It is worth noting that when using spot welding structural adhesive to achieve the bonding function, in order to ensure the bonding strength, the amount of adhesive applied must be sufficient. However, the spot welding structural adhesive is heated and cured in a drying furnace, and the colloid easily overflows from between the overlapping edges when it expands and contracts due to heat and cold. The overflowed spot welding structural adhesive forms a "scar" shape after curing, affecting the appearance of the parts. In the above embodiment, by providing a sol tank 5, the overflowed spot welding structural adhesive will preferentially flow into the sol tank 5, and after the subsequent drying furnace curing process, a smooth weld sealant will be applied to the outside to ensure the appearance of the overlapping part, while preventing rainwater flowing down the side roof from returning to the interior of the cab from the overlapping part.

[0058] In combination with the above-mentioned first aspect, the present application provides a second specific implementation method, in which a guide channel is opened on the cab body 1, one end of the guide channel is connected to the interior of the cab body 1, and the other end is connected to the gap space between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3.

[0059] It is worth noting that the gap between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3 is likely to serve as a liquid accumulation area 8 where liquid accumulates. In the above embodiment, a diversion channel is provided on the cab body 1, allowing the accumulated liquid to flow into the interior of the cab body 1 and then be discharged from the interior of the cab body 1, thereby reducing the formation of liquid accumulation and preventing the formation of a structure in which liquid is trapped between the outer cover and the beam cavity or reinforcement plate inside the cab body 1.

[0060] In combination with the above second specific implementation method, in some specific embodiments, Figure 1 、 Figure 3 and Figure 6 As shown, a drainage hole 14 is provided on the roof beam 13 of the cab body 1. Optionally, a plurality of drainage holes 14 are provided on the roof beam 13 at intervals along its length direction.

[0061] It is understood that when the cab leaves one tank and enters another, the liquid in the cavity must be completely drained, otherwise the liquid in the previous tank will flow into the next tank. Furthermore, the drainage holes 14 on the roof beam 13 serve to guide the accumulated liquid in the liquid accumulation area 8, allowing the accumulated liquid to flow from the drainage holes 14 into the interior of the cab body 1.

[0062] In combination with the above second specific implementation method, in some specific embodiments, such as Figure 4 and Figure 5 As shown, at least one drainage hole 14 is provided on the middle reinforcement plate 12 of the cab body 1 .

[0063] In some optional embodiments, in order to facilitate the positioning and overlapping of the lower cover plate assembly 3 and the upper cover plate assembly 2 in the "overbite" structure, a flange is provided at the edge of the lower cover plate assembly 3.

[0064] Furthermore, a waterproof portion is provided at the flange of the lower cover plate assembly 3. Preferably, the waterproof portion comprises a U-shaped waterproof groove 4, one end of which is connected to the rear upper crossbeam 6 of the cab body 1 and the other end extends out of the upper cover plate assembly 2.

[0065] It is understandable that rainwater often accumulates on the rear wall 32 and the rear roof 22 of the cab, and seeps into the cab through the gap between the rear wall upper crossbeam 6 and the rear lower roof cover, causing water leakage in the cab. Figure 5 As shown, one end of the rear upper cross beam 6 can be bent outward to form part of the lower cover plate assembly 3, the end of the rear upper cross beam 6 can form a lap flange, and the rear upper cross beam 6 part forms a U-shaped waterproof groove 4 structure, so that rainwater outside the cab can only be in the waterproof groove 4, and will dry naturally or be thrown out of the vehicle during driving, and will not flow into the interior of the cab.

[0066] In a third aspect, the present application provides a car, which includes: a cab, the cab including: a cab body 1, an upper cover plate assembly 2 and a lower cover plate assembly 3; wherein,

[0067] An upper cover panel assembly 2 is installed on the upper part of the cab body 1; a lower cover panel assembly 3 is installed on the lower part of the cab body 1. The lower cover panel assembly 3 and the upper cover panel assembly 2 are located on the outside of the cab body 1, and the overlapping edge of the lower cover panel assembly 3 is higher than the edge of the upper cover panel assembly 2 in the height direction of the entire vehicle.

[0068] It is worth noting that the present application sets up an "overbite" structure with the upper covering part inside and the lower covering part outside, so that the residual liquid inside the outer covering part and its beam cavity during the primer coating process of the cab can only flow back into the cab along the inside of the outer covering part, and will not flow to the outside of the outer covering part of the cab, thereby effectively reducing the paint accumulation from adhering to the surface of the outer covering such as the side panel, rear panel, and front panel to form marks, thereby damaging the quality of the electrophoretic coating on the outer covering surface and the appearance paint film quality of the cab.

[0069] In combination with the first aspect above, the present application provides a first specific implementation method, as Figure 1 and Figure 2 As shown, the overlapping edge of the side panel outer plate 311 of the side panel 31 is located outside the side roof cover plate 211 of the side roof 21 , and the edge of the side panel outer plate 311 is higher than the edge of the side roof cover plate 211 .

[0070] It is understood that the upper cover panel assembly 2 includes the side roof 21 and the rear roof 22. The lower cover panel assembly 3 includes the side panels 31 and the rear panel 32. In this application, the side panel outer panels 311 serve as the first part of the lower cover panel assembly 3. The "overbite" structure ensures that even if liquid accumulates inside the side roof cover panel 211, gravity will prevent it from flowing from the joint between the side panel outer panels 311 and the side roof cover panel 211 to the outer side, thereby affecting subsequent manufacturing processes or affecting the appearance of the cab.

[0071] In combination with the first embodiment described above, the upper cover plate assembly 2 and the lower cover plate assembly 3 are connected at their overlapped locations by using spot welding structural adhesive.

[0072] In some specific embodiments, Figure 2As shown, the side top cover plate 211 of the upper cover plate assembly 2 and the side outer plate 311 of the lower cover plate assembly 3 are connected by spot welding structural adhesive.

[0073] It is understandable that due to the structure of multiple side panels and the inability of the welding clamp entering through the door opening to reach the overlapping edges of the side top cover plate 211 and the side outer panel 311, it is inconvenient to weld the side top cover plate 211 and the side outer panel 311 at the overlapping joint, so spot welding structural glue is applied instead of welding.

[0074] In combination with the above specific embodiments, optionally, a sol tank 5 is provided at the joint between the upper cover plate assembly 2 and the lower cover plate assembly 3. Specifically, Figure 2 As shown, the outer surface of the side top cover plate 211 is provided with the sol groove 5 at the overlapping edge of the side outer plate 311.

[0075] It is worth noting that when using spot welding structural adhesive to achieve the bonding function, in order to ensure the bonding strength, the amount of adhesive applied must be sufficient. However, the spot welding structural adhesive is heated and cured in a drying furnace, and the colloid easily overflows from between the overlapping edges when it expands and contracts due to heat and cold. The overflowed spot welding structural adhesive forms a "scar" shape after curing, affecting the appearance of the parts. In the above embodiment, by providing a sol tank 5, the overflowed spot welding structural adhesive will preferentially flow into the sol tank 5, and after the subsequent drying furnace curing process, a smooth weld sealant will be applied to the outside to ensure the appearance of the overlapping part, while preventing rainwater flowing down the side top from returning to the interior of the cab from the overlapping part.

[0076] In combination with the above-mentioned first aspect, the present application provides a second specific implementation method, in which a guide channel is opened on the cab body 1, one end of the guide channel is connected to the interior of the cab body 1, and the other end is connected to the gap space between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3.

[0077] It is worth noting that the gap between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3 is likely to serve as a liquid accumulation area 8 where liquid accumulates. In the above embodiment, a diversion channel is provided on the cab body 1, allowing the accumulated liquid to flow into the interior of the cab body 1 and then be discharged from the interior of the cab body 1, thereby reducing the formation of liquid accumulation and preventing the formation of a structure in which liquid is trapped between the outer cover and the beam cavity or reinforcement plate inside the cab body 1.

[0078] In combination with the above second specific implementation method, in some specific embodiments, Figure 1 、 Figure 3 and Figure 6 As shown, a drainage hole 14 is provided on the roof beam 13 of the cab body 1. Optionally, a plurality of drainage holes 14 are provided on the roof beam 13 at intervals along its length direction.

[0079] It can be understood that the drainage holes 14 on the roof beam 13 play a guiding role on the accumulated liquid in the liquid accumulation area 8 , so that the accumulated liquid flows from the drainage holes 14 to the interior of the cab body 1 .

[0080] In combination with the above second specific implementation method, in some specific embodiments, such as Figure 4 and Figure 5 As shown, at least one drainage hole 14 is provided on the middle reinforcement plate 12 of the cab body 1 .

[0081] In some optional embodiments, in order to facilitate the positioning and overlapping of the lower cover plate assembly 3 and the upper cover plate assembly 2 in the "overbite" structure, a flange is provided at the edge of the lower cover plate assembly 3.

[0082] Furthermore, a waterproof portion is provided at the flange of the lower cover plate assembly 3. Preferably, the waterproof portion comprises a U-shaped waterproof groove 4, one end of which is connected to the rear upper crossbeam 6 of the cab body 1 and the other end extends out of the upper cover plate assembly 2.

[0083] It is understandable that rainwater often accumulates on the rear wall 32 and the rear roof 22 of the cab, and seeps into the cab through the gap between the rear wall upper crossbeam 6 and the rear lower roof cover, causing water leakage in the cab. Figure 5 As shown, one end of the rear upper cross beam 6 can be bent outward to form a part of the lower cover plate assembly 3, and the end of the rear upper cross beam 6 can form a lap flange, and the rear upper cross beam 6 part forms a U-shaped waterproof groove 4 structure, so that the rainwater outside the cab can only be in the waterproof groove 4, and naturally dry or be thrown out of the vehicle during driving, and will not flow into the cab.

[0084] In summary, the present application sets up an "overbite" structure with the upper covering part inside and the lower covering part outside, so that the residual liquid inside the outer covering part and its beam cavity during the primer coating process of the cab can only flow back into the cab along the inside of the outer covering part, and will not flow to the outside of the outer covering part of the cab, thereby effectively reducing the paint liquid from adhering to the surface of the outer covering such as the side, rear and front panels to form marks, thereby damaging the quality of the electrophoretic coating on the outer covering surface and the appearance of the paint film of the cab. Furthermore, the present application opens holes or grooves in the internal beam cavity or reinforcement plate, etc., so that the accumulated liquid can be discharged from the inside of the cab, reducing the formation of liquid accumulation.
