Description

Technical Field

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

[0002] With the increase in the number of cars, customers' requirements for cars are not limited to power performance, but also increasingly higher requirements for appearance and interior. As the core position of vehicle operation, the primer anti-corrosion and paint appearance of the entire cab give customers a good visual impact and highlight their status.

[0003] During the entire primer coating process, the cab has to go through 28 liquid tanks. The pre-treatment liquid and primer solution in the tanks will be concentrated in the clamping cavity and beam cavity of the upper top cover and other parts. When the accumulated liquid accumulates in the beam cavity and clamping cavity and enters the coating line drying furnace for drying, the accumulated liquid flowing out of the clamping cavity is dried and adheres to the outer covering surfaces such as the side wall, rear wall, and front wall to form marks, which destroys the quality of the electrophoretic coating on the outer covering surface. 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 the corrosion resistance defects of 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 to leave marks.

The lower cover panel assembly and the upper cover panel assembly are located outside the cab body, and the overlapping edge of the lower cover panel assembly is higher than the edge of the upper cover panel assembly in the height direction of the entire vehicle.

[0008] In combination with the first aspect, in one embodiment, a flange flange is provided at the edge of the lower cover plate assembly.

[0009] In combination with the first aspect, in one embodiment, a waterproof portion is provided at the flange flange of the lower cover plate assembly.

[0010] In combination with the first aspect, in one embodiment, the waterproof portion includes: a waterproof groove, which is U-shaped, and one end of the waterproof groove is connected to the upper cross beam of the rear enclosure of the cab body, and the other end extends out of the upper cover plate assembly.

[0011] In combination with the first aspect, in one embodiment, a guide channel is opened on the cab body, one end of the guide channel is connected to the interior of the cab body, and the other end is connected to the gap space between the cab body and the upper cover plate assembly or the lower cover plate assembly.

[0017] The beneficial effects brought by the technical solution provided by the embodiment of the present application include at least:

[0018] The present application arranges an "overbite" structure with an upper covering part inside and a lower covering part outside, so that the accumulated liquid remaining in 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 The liquid adheres to the surface of the outer coverings such as the side, rear and front panels to form marks, which damages the quality of the electrophoretic coating on the outer covering surface and the quality of the exterior paint film of the cab.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present application, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[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 coverings such as the side panel, rear panel, and front panel during the drying process to leave 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 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 The liquid adheres to the surface of the outer covering such as the side panel, rear panel, and front panel to form marks, which damages the quality of the electrophoretic coating on the outer covering surface and the quality of the exterior paint film of the cab.

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

[0034] It is understandable that the upper cover plate assembly 2 includes a side top 21 and a rear top 22. The lower cover plate assembly 3 includes a side enclosure 31 and a rear enclosure 32. In the present application, the side enclosure outer panel 311 is used as the first part of the lower cover plate assembly 3. The "ground-overbite" structure is used. Even if there is liquid accumulation inside the side top cover plate 211, it will not flow from the overlap between the side enclosure outer panel 311 and the side top cover plate 211 to the outer side surface under the action of gravity, thereby affecting the subsequent manufacturing process 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 the overlapped portion 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 tongs with multiple side panels and the fact that the welding tongs entering through the door opening 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 portions 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 overlap 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 spot welding structural adhesive is used 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 is easily overflowed 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 of the two.

[0040] In combination with the above-mentioned first aspect, the present application provides a second specific implementation manner, in which a diversion channel is opened on the cab body 1, one end of the diversion 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 space between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3 is easily used as a liquid accumulation area 8 where liquid accumulates. In the above embodiment, a diversion channel is provided on the cab body 1 so that the accumulated liquid can 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 accumulated liquid and preventing the formation of a structure in which the outer cover and the beam cavity or reinforcing plate inside the cab body 1 form a liquid trap.

[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 at intervals along the length direction of the roof beam 13.

[0043] It is understandable that when the cab leaves one tank and enters another tank, the liquid in the cavity must be drained, otherwise the liquid in the previous tank will flow into the next tank. Furthermore, the drainage holes 14 on the top cover beam 13 guide the accumulated liquid in the liquid accumulation area 8, so that the accumulated liquid flows from the drainage holes 14 to the inside of the cab body 1 without 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 leakage 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 "ground-to-sky" structure, a flange 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 waterproof groove 4, which is U-shaped, and one end of the waterproof groove 4 is connected to the rear upper cross beam 6 of the cab body 1, and the other end extends out of the upper cover plate assembly 2.

[0047] It is understandable that at the rear wall 32 and the rear roof 22 of the cab, rainwater often gathers on the rear wall upper cross beam 6, and penetrates into the cab through the gap between the rear wall upper cross beam 6 and the rear lower roof cover plate, causing the cab to leak. Figure 5 As shown, one end of the rear enclosure upper cross beam 6 can be bent outward to form a part of the lower covering plate assembly 3, the end of the rear enclosure upper cross beam 6 can form a lap flange, and part of the rear enclosure upper cross beam 6 forms a U-shaped waterproof groove 4 structure, so that rainwater outside the cab can only be in the waterproof groove 4, and can be naturally dried or 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 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 The liquid adheres to the surface of the outer covering such as the side panel, rear panel, and front panel to form marks, which damages the quality of the electrophoretic coating on the outer covering surface and the quality of the exterior paint film of the cab.

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

[0052] It is understandable that the upper cover plate assembly 2 includes a side top 21 and a rear top 22. The lower cover plate assembly 3 includes a side enclosure 31 and a rear enclosure 32. In the present application, the side enclosure outer panel 311 is used as the first part of the lower cover plate assembly 3. The "ground-overbite" structure is used. Even if there is liquid accumulation inside the side top cover plate 211, it will not flow from the overlap between the side enclosure outer panel 311 and the side top cover plate 211 to the outer side surface under the action of gravity, thereby affecting the subsequent manufacturing process 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 the overlapped portion 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 pliers 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 overlap 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 spot welding structural adhesive is used 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 is easily overflowed 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 of the two.

[0058] In combination with the above-mentioned first aspect, the present application provides a second specific implementation manner, in which a diversion channel is opened on the cab body 1, one end of the diversion 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 space between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3 is easily used as a liquid accumulation area 8 where liquid accumulates. In the above embodiment, a diversion channel is provided on the cab body 1 so that the accumulated liquid can 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 accumulated liquid and preventing the formation of a structure in which the outer cover and the beam cavity or reinforcing plate inside the cab body 1 form a liquid trap.

[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 at intervals along the length direction of the roof beam 13.

[0061] It is understandable that when the cab leaves one tank and enters another tank, the liquid in the cavity must be drained, otherwise the liquid in the previous tank will flow into the next tank. Furthermore, the drainage hole 14 on the top cover beam 13 guides the accumulated liquid in the liquid accumulation area 8, so that the accumulated liquid flows from the drainage hole 14 to the inside 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 leakage 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 "ground-to-sky" structure, a flange 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 waterproof groove 4, which is U-shaped, and one end of the waterproof groove 4 is connected to the rear upper cross beam 6 of the cab body 1, and the other end extends out of the upper cover plate assembly 2.

[0065] It is understandable that at the rear wall 32 and the rear roof 22 of the cab, rainwater often gathers on the rear wall upper cross beam 6, and penetrates into the cab through the gap between the rear wall upper cross beam 6 and the rear lower roof cover plate, causing the cab to leak. Figure 5 As shown, one end of the rear enclosure upper cross beam 6 can be bent outward to form a part of the lower covering plate assembly 3, the end of the rear enclosure upper cross beam 6 can form a lap flange, and part of the rear enclosure upper cross beam 6 forms a U-shaped waterproof groove 4 structure, so that rainwater outside the cab can only be in the waterproof groove 4, and can be naturally dried or 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 includes: 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 an "overbite" structure with the upper covering part inside and the lower covering part outside, so that the accumulated liquid remaining 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 The liquid adheres to the surface of the outer covering such as the side panel, rear panel, and front panel to form marks, which damages the quality of the electrophoretic coating on the outer covering surface and the quality of the exterior paint film of the cab.

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

[0070] It is understandable that the upper cover plate assembly 2 includes a side top 21 and a rear top 22. The lower cover plate assembly 3 includes a side enclosure 31 and a rear enclosure 32. In the present application, the side enclosure outer panel 311 is used as the first part of the lower cover plate assembly 3. The "ground-overbite" structure is used. Even if there is liquid accumulation inside the side top cover plate 211, it will not flow from the overlap between the side enclosure outer panel 311 and the side top cover plate 211 to the outer side surface under the action of gravity, thereby affecting the subsequent manufacturing process 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 the overlapped portion 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 welding tongs entering through the door opening cannot 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 portion, so spot welding structural glue is applied to replace welding.

[0074] In combination with the above specific embodiments, optionally, a sol tank 5 is provided at the overlap 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 spot welding structural adhesive is used 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 is easily overflowed 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 of the two.

[0076] In combination with the above-mentioned first aspect, the present application provides a second specific implementation manner, in which a diversion channel is opened on the cab body 1, one end of the diversion 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 space between the cab body 1 and the upper cover plate assembly 2 or the lower cover plate assembly 3 is easily used as a liquid accumulation area 8 where liquid accumulates. In the above embodiment, a diversion channel is provided on the cab body 1 so that the accumulated liquid can 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 accumulated liquid and preventing the formation of a structure in which the outer cover and the beam cavity or reinforcing plate inside the cab body 1 form a liquid trap.

[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 at intervals along the length direction of the roof beam 13.

[0079] It can be understood that the drainage holes 14 on the roof beam 13 play a guiding role for 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 leakage 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 "ground-to-sky" structure, a flange 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 waterproof groove 4, which is U-shaped, and one end of the waterproof groove 4 is connected to the rear upper cross beam 6 of the cab body 1, and the other end extends out of the upper cover plate assembly 2.

[0083] It is understandable that at the rear wall 32 and the rear roof 22 of the cab, rainwater often gathers on the rear wall upper cross beam 6, and penetrates into the cab through the gap between the rear wall upper cross beam 6 and the rear lower roof cover plate, causing the cab to leak. 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 dried or thrown out of the vehicle during driving, and will not flow into the cab.

[0084] In summary, the present application sets an "overbite" structure with the upper cover inside and the lower cover outside, so that the residual liquid inside the outer cover and its beam cavity during the primer coating process can only flow back into the cab along the inside of the outer cover, and will not flow to the outside of the outer cover of the cab, thereby effectively reducing the paint accumulation on the surface of the side, rear, front and other external covers to form marks, destroying the quality of the electrophoretic coating on the external covering surface and the appearance of the cab. Furthermore, the present application opens holes or grooves on the internal beam cavity or reinforcing plate to allow the accumulated liquid to be discharged inside the cab, reducing the formation of accumulated liquid.

[0085] In the description of the present application, it should be noted that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
