Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a cab air intake embedding structure and a commercial vehicle. Background Technology

[0002] In the freight sector, especially in express delivery and beverage transportation, goods are very light. Therefore, the limiting factor in transportation is not weight, but volume. Larger cargo boxes mean larger volumes, allowing more goods to be transported per trip. This increases transportation capacity, efficiency, and added value, resulting in greater economic benefits.

[0003] Since the overall length of the vehicle is fixed, the length of the cargo box determines the vehicle's carrying capacity. Therefore, the shorter the cab length, the better, provided that the cab layout space is sufficient. In traditional layouts, the air intake assembly is located at the rear of the cab, and the rear outer panel of the cab is almost flat. Installing the air intake assembly on the rear outer panel increases the length of the cab.

[0004] Existing air intake assemblies are all independent structures, typically including the air intake pipe. Although some cabs have a portion of the rear outer panel recessed to accommodate the air intake pipe, the clearance left for the vibration damping structure in the air intake assembly will additionally occupy the cab's usable space. The air intake pipe is usually connected to the cab by a bracket, which still encroaches on the cab's space. Summary of the Invention

[0005] The purpose of this invention is to provide a cab air intake embedded structure and a commercial vehicle to make full use of the vehicle space.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0007] A cab air intake duct embedded structure includes:

[0008] The cab body includes a rear outer panel and side outer panels distributed on the left and right sides of the rear outer panel, wherein a portion of the outer surface of the rear outer panel and / or the side outer panels is recessed to form a groove.

[0009] The outer plate of the air duct is completely embedded in the groove. The outer plate of the air duct and the inner wall of the groove form an air intake channel. The air intake channel has an air inlet and an air outlet. The air inlet is connected to the outside, and the air outlet is connected to the air intake system of the engine. The outer plate of the air duct is connected to the cab body by a locking device.

[0012] Preferably, the front stepped surface includes a first stepped surface and a second stepped surface arranged from front to back. The second stepped surface is concave relative to the first stepped surface. A first sealing structure is sandwiched between the airway outer plate and the first stepped surface. The outer surface of the airway outer plate is concave to form a receiving groove corresponding to the position of the second stepped surface. The locking member is provided in the receiving groove.

[0013] Preferably, the device also includes a cover plate, which is embedded in the receiving groove to cover the locking member, and the cover plate is flush with the outer side panel.

[0014] Preferably, the groove is located at the rear end of the side panel, the bottom of the groove has an L-shaped cross-section, and a rear stepped surface is provided on the rear side of the bottom of the groove. The rear stepped surface is concave relative to the bottom of the groove, and the rear side of the air passage panel is connected to the rear stepped surface by the locking member.

[0015] Preferably, a sealing surface is inclinedly provided between the rear stepped surface and the bottom of the groove, and a second sealing structure is sandwiched between the outer plate of the air passage and the sealing surface.

[0016] Preferably, the groove is provided on the rear outer panel, or the groove is provided at the junction of the rear outer panel and the side outer panel, with a portion of the outer surface of the rear outer panel recessed to form a first groove, and a portion of the outer surface of the side outer panel recessed to form a second groove, the first groove and the second groove communicating to form the groove.

[0017] Preferably, the outer plate of the airway includes an airway side plate and an airway bottom plate. The airway bottom plate is located at the bottom of the airway side plate. The air inlet is disposed on the airway side plate, and the air outlet is disposed on the airway bottom plate. A third sealing structure is sandwiched between the airway bottom plate and the inner wall of the groove.

[0018] A commercial vehicle includes a cargo box and a cab air intake embedded structure as described above, the cargo box being disposed behind the cab body and the cab body being connected to the cargo box.

[0019] The beneficial effects of this invention are:

[0020] The proposed cab air intake duct embedded structure comprises a rear outer panel and side outer panels distributed on the left and right sides of the rear outer panel. Parts of the outer surfaces of the rear and / or side outer panels are recessed to form grooves. The air intake duct outer panels are completely embedded in these grooves, forming an air intake channel with the inner wall of the groove.

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] See Figures 1 to 7 This embodiment provides a cab air intake duct embedded structure, including a cab body and an air duct outer plate 21. The cab body includes a rear outer plate 11 and side outer plates 12 distributed on the left and right sides of the rear outer plate 11. Part of the outer surface of the rear outer plate 11 and / or the side outer plates 12 are recessed to form a groove 100. The air duct outer plate 21 is completely embedded in the groove 100. The air duct outer plate 21 and the inner wall of the groove 100 form an air intake channel 200. The air intake channel 200 has an air inlet 210 and an air outlet 220. The air inlet 210 is connected to the outside, and the air outlet 220 is connected to the engine's air intake system. The air duct outer plate 21 and the cab body are connected by a locking member.

[0047] By fully embedding the outer air duct plate 21 into the groove 100, the length of the cab body is not occupied, thus making full use of the overall length of the machine. The air intake channel 200 is formed by the outer air duct plate 21 and the inner wall of the groove 100, and is no longer an independent pipe structure, reducing space occupation. Furthermore, the outer air duct plate 21 is connected to the cab body by a locking device, which facilitates assembly, occupies little space, and has a more compact structure, thereby improving space utilization while ensuring air intake function.

[0048] Taking the cab body as a reference, the front-to-back, left-to-right, and up-down directions are defined. The groove 100 can be located on the rear outer panel 11, the left side outer panel 12, or the right side outer panel 12. Alternatively, some grooves 100 can be located on the side outer panel 12, and others on the rear outer panel 11. In this embodiment, the groove 100 is located on the right side outer panel 12 as an example. The overall length of the vehicle is the length of the vehicle along the front-to-back direction.

[0049] Along the left-right direction of the cab body, the outer panel 21 of the air duct is flush with the outer panel 12 of the side wall. This reduces wind resistance, thereby reducing energy consumption during vehicle operation. By aligning the outer panel 21 of the air duct with the outer panel 12 of the side wall, a larger flow area can also be ensured for the air intake passage 200.

[0050] The air duct outer panel 21 and the side panel outer panel 12 have a uniform surface transition with no obvious surface difference, and the gap at the fitting position of the two is uniform. Along the front of the cab body, the air duct outer panel 21 does not exceed the B-pillar boundary of the cab body. The cab body also includes an interior trim panel 13, which transitions uniformly from the B-pillar to the rear panel with no obvious surface difference; the air duct outer panel 21 meets the air intake area requirements in the front-rear direction; and in the vertical direction, it does not exceed the upper crossbeam of the side panel of the cab body.

[0051] The groove 100 includes a groove bottom 110 and a front stepped surface 120. The front stepped surface 120 is located on the front side of the groove bottom 110. The groove bottom 110 is concave relative to the front stepped surface 120, and the front stepped surface 120 is concave relative to the side outer panel 12. The front side of the airway outer panel 21 is connected to the front stepped surface 120. By providing the front stepped surface 120, it is easy to connect the airway outer panel 21 to the side outer panel 12, ensuring that the airway outer panel 21 does not extend beyond the side outer panel 12.

[0052] The front stepped surface 120 includes a first stepped surface 121 and a second stepped surface 122 arranged from front to back. The second stepped surface 122 is concave relative to the first stepped surface 121. A first sealing structure 31 is sandwiched between the air duct outer plate 21 and the first stepped surface 121. The outer surface of the air duct outer plate 21 is concave at the position corresponding to the second stepped surface 122 to form a receiving groove 201, and a locking member is provided in the receiving groove 201. The first stepped surface 121 is used to abut against the first sealing structure 31 to increase the contact area, and the first sealing structure 31 is located on the front side of the locking member to prevent moisture from entering and damaging the locking member. The first sealing structure 31 can be pressed tightly when the locking member is installed. By providing the receiving groove 201 at the position corresponding to the second stepped surface 122 on the outer surface of the air duct outer plate 21, and providing the locking member in the receiving groove 201, the locking member is prevented from protruding from the air duct outer plate 21, ensuring the flatness of the air duct outer plate 21 and reducing wind resistance.

[0053] The step difference between the bottom of the groove 110 and the second stepped surface 122 is 100-110mm, the step difference between the second stepped surface 122 and the first stepped surface 121 is 15-20mm, and the step difference between the first stepped surface 121 and the outer side panel 12 is 5-10mm.

[0054] The outer panel 21 of the air duct has mounting holes 202 corresponding to the positions where the locking components are installed. The cab air intake duct embedded structure also includes a cover plate 41, which is embedded in the receiving groove 201 to cover the locking components. The cover plate 41 is flush with the outer side panel 12. By setting the cover plate 41 to cover the locking components, on the one hand, it ensures a clean appearance, and the cover plate 41 also protects the locking components; on the other hand, the cover plate 41 being embedded in the receiving groove 201 and flush with the outer side panel 12 reduces wind resistance. The cover plate 41 can be made of plastic sheet, which has a certain degree of elasticity and can be pressed into the receiving groove 201, eliminating the need for a separate locking structure and preventing the cover plate 41 from falling off.

[0055] In this embodiment, the groove 100 is disposed at the rear end of the side panel 12, and the cross-section of the groove bottom 110 is L-shaped. This makes full use of the rear end space of the side panel.

[0056] A rear stepped surface 130 is provided on the rear side of the groove bottom 110. The rear stepped surface 130 is concave relative to the groove bottom 110, and the rear side of the air passage outer plate 21 is connected to the rear stepped surface 130 by a locking member. Specifically, the rear outer plate 11 is welded to the side outer plate 12, and the rear stepped surface 130 is provided at the weld between the rear outer plate 11 and the side outer plate 12. The weld between the rear outer plate 11 and the side outer plate 12 forms a weld edge, and the rear stepped surface 130 is provided on the weld edge.

[0057] A sealing surface 140 is inclinedly provided between the rear stepped surface 130 and the bottom of the groove 110, and a second sealing structure 32 is sandwiched between the outer plate 21 of the air passage and the sealing surface 140. The sealing surface 140 is used to abut against the second sealing structure 32 to increase the contact area.

[0058] Specifically, the airway outer plate 21 includes an airway side plate 211 and an airway bottom plate 212, with the bottom plate 212 located at the bottom of the airway side plate 211. The front side of the airway side plate 211 is connected to the front stepped surface 120, and the rear side of the airway side plate 211 is connected to the rear stepped surface 130.

[0059] In this embodiment, the airway side plate 211 is L-shaped. A first connecting plate 213 and a first sealing plate 214 are sequentially arranged from back to front on the front side of the airway side plate 211. The first connecting plate 213 is a U-shaped plate to form a receiving groove 201, and the first sealing plate 214 is a flat plate to facilitate cooperation with the first sealing structure 31. A second sealing plate 215 and a second connecting plate 216 are sequentially arranged from front to back on the rear side of the airway side plate 211. The second sealing plate 215 is a flat plate to facilitate cooperation with the second sealing structure 32, and the second connecting plate 216 is a flat plate.

[0060] In this embodiment, the air inlet 210 is disposed on the air duct side plate 211, and the air outlet 220 is disposed on the air duct bottom plate 212. The air inlet 210 in this embodiment is rectangular, with its center 1600mm above the ground and its lower edge 1500mm above the ground. A third sealing structure is sandwiched between the air duct bottom plate 212 and the inner wall of the groove 100.

[0061] The cab body includes a side upper crossbeam. In the vertical direction, the air duct outer plate 21 does not extend beyond the side upper crossbeam, so the groove 100 does not penetrate the cab body in the vertical direction. When the groove 100 is provided on the side outer plate 12, the groove 100 is usually formed by stamping. At the top of the groove 100, part of the side outer plate 12 serves as the top surface of the groove 100.

[0062] A mating structure 51 is provided on the top of the groove 100 and on the outer side panel 12. The outer air passage panel 21 abuts against the mating structure 51, and a fourth sealing structure is sandwiched between them. This seals the top of the air intake passage 200. The mating structure 51 can be a stepped surface or a protrusion, and there is no limitation on it.

[0063] A flared structure 217 is provided on the air intake 210 of the air duct base plate 212, which can be connected to the bellows to facilitate connection to the engine air intake 210.

[0064] The outer plate of the air duct 21 is a one-piece molded structure, which is convenient for processing and production and ensures structural strength.

[0065] The first sealing structure 31, the second sealing structure 32, the third sealing structure, and the fourth sealing structure can be sealing gaskets. The locking element can be screws, which can be installed by driving screws during assembly, making assembly convenient and saving time. During assembly, the sealing gasket can be first bonded to the outer airway plate 21, then the outer airway plate 21 can be embedded into the groove 100 and fixed by driving screws. The locking element can also be bolts. The first sealing structure 31, the second sealing structure 32, the third sealing structure, and the fourth sealing structure can also be adhesive layers, which are used to seal the periphery of the outer airway plate 21 after assembly by injecting adhesive.

[0066] Optionally, a flow guide structure is provided within the air intake channel 200 to guide airflow and ensure airflow stability. The flow guide structure can be a guide plate or a flow guide protrusion. The flow guide structure can be installed on the inner wall of the outer air duct plate 21 and can be integrally formed with the outer air duct plate 21. Optionally, a reinforcing structure is provided within the air intake channel 200 to increase structural strength and reduce vibration. A grid or filter screen is provided at the air intake port 210 to prevent larger foreign objects from entering the air intake channel 200.

For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The difference is that the groove 100 is provided on the front side of the rear end of the side panel 12, and the cross-section of the groove bottom 110 is U-shaped.

[0069] The rear stepped surface 130 includes a third stepped surface 131 and a fourth stepped surface 132 arranged from front to back. The third stepped surface 131 is concave relative to the fourth stepped surface 132. A second sealing structure 32 is sandwiched between the air passage outer plate 21 and the fourth stepped surface 132. The outer surface of the air passage outer plate 21 is concave to form a receiving groove 201 corresponding to the position of the third stepped surface 131. A locking element is provided in the receiving groove 201.

[0070] In this embodiment, the airway side plate 211 is U-shaped. A first connecting plate 213 and a first sealing plate 214 are sequentially arranged from back to front on the front side of the airway side plate 211.

The difference is that the groove 100 is provided on the rear outer panel 11. Along the front-rear direction of the cab body, the air duct outer panel 21 is flush with the rear outer panel 11. This can reduce wind resistance, thereby reducing energy consumption during vehicle operation. By making the air duct outer panel 21 flush with the rear outer panel 11, the air intake passage 200 can also be ensured to have a large flow area.

[0073] The air duct outer panel 21 and the rear outer panel 11 have a uniform surface transition with no obvious surface difference, and the gap at the fitting position of the two is uniform. The gap does not exceed the upper crossbeam of the side panel of the cab body in the vertical direction.

[0080] Figure 12 Embodiment 4 is shown. For simplicity, only the differences between Embodiment 4 and Embodiment 1 are described. The difference is that the groove 100 is provided at the junction of the rear outer panel 11 and the side outer panel 12. A portion of the outer surface of the rear outer panel 11 is recessed to form a first groove, and a portion of the outer surface of the side outer panel 12 is recessed to form a second groove. The first groove and the second groove are connected to form the groove 100.

[0081] The groove 100 includes a groove bottom 110, a front stepped surface 120, and a rear stepped surface 130. The front stepped surface 120 is recessed relative to the side outer panel 12, and the front side of the air passage outer panel 21 is connected to the front stepped surface 120. By providing the front stepped surface 120, it is easy to connect the air passage outer panel 21 to the side outer panel 12, and it can be ensured that the air passage outer panel 21 does not extend beyond the side outer panel 12.

[0082] A rear stepped surface 130 is provided on the rear side of the bottom of the groove 110. The rear stepped surface 130 is concave relative to the rear outer plate 11, and the rear side of the air passage outer plate 21 is connected to the rear stepped surface 130.
