Abstract
Description
Technical Field
[0001] This application relates to the field of commercial vehicle cab technology, and in particular to a commercial vehicle cab and vehicle that integrates drainage and a front downward-facing mirror. Background Technology
[0002] Because large vehicles often have blind spots in front of them, drivers cannot see what's in front of them, causing inconvenience when starting and driving. The front downward-facing mirror is a crucial safety feature for drivers, supplementing the lower frontal blind spot and improving driving safety.
[0003] In related technologies, in the design of commercial vehicle cabs, in rainy weather, water tends to accumulate above the doors on the roof, and rainwater flowing onto the door windows can also affect visibility in rainy conditions. To prevent rainwater from flowing onto the door windows, a drainage structure is installed on the side of the cab. This drainage structure prevents excessive rainwater from flowing onto the door windows, making it easier to observe the rearview mirrors from the cab and improving driving safety.
[0004] However, after the drainage structure is installed on the side of the cab, the front lower view mirror is also placed on the front top side. The installation position of the front lower view mirror support and the cab coincides with the placement position of the drainage structure, which leads to a decrease in the drainage effect of the drainage structure and an increase in driving safety risks. Summary of the Invention
[0005] This application provides a commercial vehicle cab and vehicle that integrates drainage and a front lower view mirror, in order to solve the problem in the related art where the installation position of the front lower view mirror support and the cab coincides with the arrangement position of the drainage structure, resulting in poor drainage effect of the drainage structure and increased driving safety risks.

A support cover plate that overlaps with the front end of the side roof trim strip is connected to the outer wall of the front lower mirror support.
[0008] In some embodiments: The welding joint between the roof side wall and the side wall sheet metal is bent inward toward the cab body to form a "C" - shaped structure, so that the outer walls of the side roof trim strip and the support cover plate are coplanar with the roof side wall, and a water inlet is reserved between the top of the side roof trim strip and the support cover plate and the roof side wall.
[0009] In some embodiments: A first mounting hole is provided on the diversion section. The first mounting hole is located in the rainwater diversion groove and is connected to the cab side wall through a bolt. A first sealing gasket is connected between the diversion section and the cab side wall. A second mounting hole connecting to the A - pillar is provided on the drainage section, and bolts penetrating through the second mounting hole and connecting to the A - pillar are provided on the drainage section.
[0010] In some embodiments: A first water - blocking strip that protrudes upward and is spaced from the roof side wall is provided at the top of the diversion section. The first water - blocking strip, the diversion section, the first sealing gasket, and the roof side wall jointly enclose the upper - layer diversion groove with an open top; A second water - blocking strip that protrudes downward and is spaced from the roof side wall is provided at the bottom of the diversion section. The second water - blocking strip is connected to the welded bead through the sealing foam. The diversion section, the first sealing gasket, the roof side wall, the sealing foam, and the second water - blocking strip jointly enclose the lower - layer diversion groove with two open ends and a closed perimeter.
[0011] In some embodiments: A second sealing gasket is hermetically connected between the support cover plate and the first water - blocking strip. A third sealing gasket is hermetically connected between the side roof trim strip and the front lower mirror support. The top end of the third sealing gasket is connected to the second sealing gasket, and the bottom end of the third sealing gasket is connected to the sealing foam; A pressing strip is provided at one end of the support cover plate. The pressing strip presses both ends of the third sealing gasket against the second sealing gasket and the sealing foam respectively.
[0012] In some embodiments: the guide section is provided with a plurality of intersecting horizontal and vertical ribs on the side near the cab side wall, the depth of the vertical ribs is less than the depth of the horizontal ribs, and the plurality of horizontal ribs are sealed to the cab side wall through the first sealing gasket to form the upper guide channel and the lower guide channel.
[0013] In some embodiments: the drainage section is located at the front end of the guide section and extends downward relative to the guide section. The drainage section is provided with a front water barrier and a rear water barrier on the side near the cab side wall. The width between the front water barrier and the rear water barrier gradually narrows in the direction away from the guide section.

[0014] In some embodiments: the outlets of the upper and lower guide channels are both located between the front and rear water-blocking sides, and a sealing block is provided on the top of the rear water-blocking side. The sealing block is used to guide the water flow of the lower guide channel to the drain channel.
[0015] A second aspect of this application provides a vehicle comprising a commercial vehicle cab with integrated drainage and a front-view mirror as described in any of the above embodiments.
[0016] The beneficial effects of the technical solution provided in this application include: This application provides a commercial vehicle cab and vehicle with integrated drainage and a front lower view mirror. The commercial vehicle cab with integrated drainage and a front lower view mirror of this application includes a cab body, which comprises a cab side panel and a cab door. The outer wall of the cab side panel is provided with a rainwater guide channel located above the cab door, extending from the rear panel of the cab body to the A-pillar of the cab body. The front lower view mirror includes a front lower view mirror support, which includes a guide section and a drainage section connected to each other. The guide section is fixed within the rainwater guide channel and together forms an upper guide channel and a lower guide channel separated from each other. The drainage section is fixed on the A-pillar and together forms a drain channel connecting the upper and lower guide channels.
[0017] Therefore, the commercial vehicle cab with integrated drainage and a front downward-facing mirror of this application has a rainwater guide channel located above the cab door on the outer wall of the cab side panel. The rainwater guide channel extends from the rear panel of the cab body to the A-pillar of the cab body. A portion of the rainwater on the top of the cab side is guided into the rainwater guide channel above the cab door, preventing a large amount of rainwater from flowing onto the door glass. This allows the driver to easily observe the front downward-facing mirror and rearview mirror from inside the cab, even in rainy weather, thus improving driving safety.
[0018] In addition, the guide section of the front lower mirror is fixed in the rainwater guide channel and together they form an upper guide channel and a lower guide channel that are separated from each other. Another part of the rainwater on the top of the side of the cab is guided into the upper guide channel above the cab door, preventing a large amount of rainwater from flowing onto the door glass. After entering the lower guide channel, the rainwater enters the drain channel together with the rainwater in the upper guide channel and enters the drain channel. The rainwater discharged from the drain channel flows down the A-pillar to the ground.
[0019] The guide section of the front lower-view mirror can not only be installed in the rainwater drainage channel, but also form an upper and lower drainage channel together with the rainwater drainage channel. This provides an installation position for the front lower-view mirror on the side wall of the cab without affecting the normal drainage of the rainwater drainage channel. The drainage section is fixed to the A-pillar, and the guide section is fixed in the rainwater drainage channel. This makes the installation points of the front lower-view mirror bracket on the cab more dispersed. This not only reduces the stress on the front lower-view mirror bracket and the installation points in the cab, but also allows the rainwater discharged from the drainage channel to flow downwards along the A-pillar, preventing rainwater from flowing from the drainage channel to the door glass while the vehicle is in motion.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] This application provides a commercial vehicle cab and vehicle that integrates drainage and a front lower view mirror, which can solve the problem in related technologies where the installation position of the front lower view mirror support and the cab coincides with the arrangement position of the drainage structure, resulting in poor drainage effect of the drainage structure and increased driving safety risks.
[0025] See Figures 1 to 8 As shown, a first aspect of this application provides a commercial vehicle cab integrating drainage and a front downward-facing mirror, comprising: The cab body 10 includes a cab side panel and a cab door 14. The outer wall of the cab side panel is provided with a rainwater drainage channel 13 located above the cab door 14. The rainwater drainage channel 13 extends from the rear of the cab body 10 to the A-pillar 16 of the cab body 10. Rainwater flowing down from the top of the cab body 10 enters the rainwater drainage channel 13 and is then concentrated and discharged to the rear of the cab body 10 and the A-pillar 16, thereby preventing rainwater from flowing directly downwards onto the cab door 14 and obscuring the light transmittance of the door glass.
[0026] The front lower view mirror 20 includes a front lower view mirror support 21, which is used to fix the front lower view mirror 20 to the side wall of the driver's cab. The front lower view mirror support 21 includes a guide section 22 and a drainage section 28 connected to each other. The guide section 22 is fixed in the rainwater guide channel 13 and together with the rainwater guide channel 13 forms an upper guide channel 23 and a lower guide channel 24 that are separated vertically. The drainage section 28 is fixed on the A-pillar 16 and together with the A-pillar 16 forms a drain channel 29 that connects the upper guide channel 23 and the lower guide channel 24.
[0027] The commercial vehicle cab with integrated drainage and a front lower-view mirror in this embodiment has a rainwater guide channel 13 located above the cab door 14 on the outer wall of the cab side panel. The rainwater guide channel 13 extends from the rear panel of the cab body 10 to the A-pillar 16 of the cab body 10. A portion of the rainwater on the top of the cab side is guided into the rainwater guide channel 13 above the cab door 14, preventing a large amount of rainwater from flowing onto the door glass. This allows the driver to easily observe the front lower-view mirror 20 and the rearview mirror 15 from the cab even in rainy weather, improving driving safety.
[0028] In addition, the guide section 22 of the front lower mirror 20 is fixed in the rainwater guide channel 13 and together they form an upper guide channel 23 and a lower guide channel 24 that are separated from each other. Another part of the rainwater on the top of the side of the cab is guided into the upper guide channel 23 above the cab door 14, preventing a large amount of rainwater from flowing onto the door glass. After entering the lower guide channel 24, the rainwater in the rainwater guide channel 13 and the rainwater in the upper guide channel 23 enter the drain channel 29 together. The rainwater discharged from the drain channel 29 is discharged down the A-pillar 16 to the ground.
[0029] The guide section 22 of the front lower view mirror 20 can not only be installed in the rainwater guide channel 13, but also form the upper guide channel 23 and the lower guide channel 24 together with the rainwater guide channel 13. This provides an installation position for the front lower view mirror 20 on the side wall of the cab without affecting the normal drainage of the rainwater guide channel 13. The drainage section 28 is fixed to the A-pillar 16, and the guide section 22 is fixed in the rainwater guide channel 13. This makes the installation points of the front lower view mirror support 21 on the cab more dispersed. This not only reduces the stress on the front lower view mirror support 21 and the cab installation point, but also allows the rainwater discharged from the drain channel 29 to flow down the A-pillar 16, preventing the rainwater discharged from the drain channel 29 from flowing towards the door glass while the vehicle is in motion.
[0030] In some alternative embodiments: see Figures 1 to 4As shown in the figure, an embodiment of the present application provides a commercial vehicle cab integrating drainage and a front lower view mirror. The cab side wall of the commercial vehicle cab includes a roof side wall 12 and a side wall sheet metal 11. The roof side wall 12 and the side wall sheet metal 11 are welded to each other and form a welding bead 17 protruding outside the cab body 10. The welding bead 17 is connected with a side roof decorative strip 19 through a sealing foam 18.
[0031] The side roof decorative strip 19 is used to decorate and cover the welding bead 17 formed by the mutual welding connection of the roof side wall 12 and the side wall sheet metal 11 and protruding outside the cab body 10. And the side roof decorative strip 19 is connected with the welding bead 17 through the sealing foam 18. Furthermore, the roof side wall 12, the welding bead 17, the sealing foam 18 and the side roof decorative strip 19 together enclose a rainwater diversion groove 13 with an open top. The open top of the rainwater diversion groove 13 is used to converge a part of the rainwater from the top of the cab side into the rainwater diversion groove 13.
[0032] The rear end of the side roof decorative strip 19 extends to the rear wall of the cab body 10, and the front end of the side roof decorative strip 19 extends to the front lower view mirror support 21. A support cover plate 26 that overlaps with the front end of the side roof decorative strip 19 is connected to the outer wall of the front lower view mirror support 21. The support cover plate 26 is used to decorate and cover the front lower view mirror support 21, and the support cover plate 26 and the front lower view mirror support 21 are connected by snap fasteners. The outer wall surface of the side roof decorative strip 19 is flush with the outer wall surface of the support cover plate 26, thereby improving the aesthetic appearance of the cab side wall.
[0033] In some optional embodiments: Refer to Figure 3 and Figure 4 As shown in the figure, an embodiment of the present application provides a commercial vehicle cab integrating drainage and a front lower view mirror. The welding joint of the roof side wall 12 and the side wall sheet metal 11 of the commercial vehicle cab is bent inward toward the cab body 10 to form a "C" - shaped structure, so that the outer walls of the side roof decorative strip 19 and the support cover plate 26 are coplanar with the roof side wall 12, and water inlets are reserved between the top of the side roof decorative strip 19 and the support cover plate 26 and the roof side wall 12.
[0034] In the embodiment of the present application, the welding joint of the roof side wall 12 and the side wall sheet metal 11 is bent inward toward the cab body 10 to form a "C" - shaped structure (that is, the welding joint of the roof side wall 12 and the side wall sheet metal 11 forms a groove with an outward opening toward the cab body 10). When the side roof decorative strip 19 is connected through the sealing foam 18 and the welding bead 17, and after the support cover plate 26 is connected with the front lower view mirror support 21, the outer walls of the side roof decorative strip 19 and the support cover plate 26 are coplanar with the roof side wall 12, further improving the aesthetic appearance of the cab side wall.
[0035] In some optional embodiments: Refer to Figure 4 、 Figure 7 and Figure 8 As shown in the illustration, this application provides a commercial vehicle cab integrating drainage and a front lower-view mirror. The cab's guide section 22 has two spaced-apart first mounting holes 31 located within a rainwater guide channel 13 and connected to the cab sidewall via bolts 30. A first sealing gasket 25 connects the guide section 22 to the cab sidewall. The drainage section 28 has a second mounting hole 32 for connecting to the A-pillar 16, and a bolt 30 passes through the second mounting hole 32 and connects to the A-pillar 16.
[0036] In this embodiment, two spaced-apart first mounting holes 31 are provided on the guide section 22, and a second mounting hole 32 connecting to the A-pillar 16 is provided on the drainage section 28. The guide section 22 and the drainage section 28 are respectively fastened to the cab side wall and the A-pillar 16 by bolts 30, which helps to disperse the mounting points at the connection between the front lower view mirror 20 and the cab body 10, and improves the structural strength of the front lower view mirror 20. A first sealing gasket 25 is connected between the guide section 22 and the cab side wall. The first sealing gasket 25 is used to seal the first mounting holes 31, thereby preventing rainwater in the rainwater diversion channel 13 from entering the cab body 10 through the first mounting holes 31.
[0037] In some alternative embodiments: see Figure 2 and Figure 4 As shown, this application embodiment provides a commercial vehicle cab integrating drainage and a front lower view mirror. The top of the guide section 22 of the commercial vehicle cab is provided with a first water-blocking strip that protrudes upward and is spaced apart from the top cover side wall 12. The first water-blocking strip, the guide section 22, the first sealing gasket 25 and the top cover side wall 12 together form the upper guide channel 23 with an open top.
[0038] The bottom of the flow guide section 22 is provided with a second water-blocking strip that protrudes downward and is spaced apart from the top cover side wall 12. The second water-blocking strip is connected to the weld stop 17 through sealing foam 18. The flow guide section 22, the first sealing gasket 25, the top cover side wall 12, the sealing foam 18 and the second water-blocking strip together form the lower flow guide groove 24, which is open at both ends and closed on all sides.
[0039] In this embodiment, a first water-blocking strip is provided at the top of the guide section 22, protruding upwards and spaced apart from the top cover side wall 12. The first water-blocking strip and the guide section 22 are integrally formed. The first water-blocking strip and the top cover side wall 12 are spaced apart and thus can mutually form the upper guide channel 23 with an open top. A second water-blocking strip is provided at the bottom of the guide section 22, protruding downwards and spaced apart from the top cover side wall 12. The second water-blocking strip and the guide section 22 are integrally formed. The second water-blocking strip and the top cover side wall 12 are spaced apart and connected to the welded stop 17 through sealing foam 18, thus mutually forming the lower guide channel 24 with open ends and closed perimeter.
[0040] In some alternative embodiments: see Figure 2 , Figure 5 and Figure 6 As shown in the figure, this application embodiment provides a commercial vehicle cab integrating drainage and a front lower view mirror. A second sealing gasket 27 is sealingly connected between the support cover plate 26 and the first water deflector strip of the commercial vehicle cab. A third sealing gasket 36 is sealingly connected between the side top trim strip 19 and the front lower view mirror support 21. The top end of the third sealing gasket 36 is connected to the second sealing gasket 27, and the bottom end of the third sealing gasket 36 is connected to the sealing foam 18.
[0041] A pressure strip 37 is provided at one end of the support cover plate 26, which presses the two ends of the third sealing gasket 36 tightly onto the second sealing gasket 27 and the sealing foam 18, respectively. In this embodiment, to achieve waterproof sealing at the overlap between the side top decorative strip 19 and the front lower mirror support 21, a third sealing gasket 36 is provided between the side top decorative strip 19 and the front lower mirror support 21. The third sealing gasket 36 fills the water-permeable gap between the side top decorative strip 19 and the front lower mirror support 21. Furthermore, the top end of the third sealing gasket 36 is connected to the second sealing gasket 27, and the bottom end is connected to the sealing foam 18, further improving the sealing performance. The third sealing gasket 36, the second sealing gasket 27, and the sealing foam 18 can be designed as a separate structure or an integrated connection structure.
[0042] In some alternative embodiments: see Figure 7 and Figure 8 As shown in the embodiment of this application, a commercial vehicle cab integrating drainage and a front lower view mirror is provided. The guide section 22 of the commercial vehicle cab is provided with multiple intersecting horizontal ribs 34 and vertical ribs 35 on the side near the cab side wall. The depth of the vertical ribs 35 is less than the depth of the horizontal ribs 34. The multiple horizontal ribs 34 are sealed to the cab side wall through a first sealing gasket 25 to form an upper guide channel 23 and a lower guide channel 24.
[0043] The transverse ribs 34 and longitudinal ribs 35 in this embodiment can not only enhance the structural strength of the guide section 22, but also form an upper guide channel 23 and a lower guide channel 24 by sealing the multiple transverse ribs 34 with the side wall of the cab through the first sealing gasket 25. This simplifies the structural design of the guide section 22, enabling not only structural enhancement but also the formation of the upper guide channel 23 and the lower guide channel 24.
[0044] In some alternative embodiments: see Figure 7 and Figure 8As shown, this application embodiment provides a commercial vehicle cab integrating drainage and a front downward-facing mirror. The drainage section 28 of the commercial vehicle cab is located at the front end of the guide section 22 and extends downwards relative to the guide section 22. The drainage section 28 has a front water deflector and a rear water deflector on the side of the cab near the side wall. The width between the front water deflector and the rear water deflector gradually narrows in the direction away from the guide section 22. The drainage section 28, the front water deflector, the rear water deflector, and the A-pillar 16 together form a drainage groove 29.
[0045] The outlets of both the upper guide channel 23 and the lower guide channel 24 are located between the front and rear water barriers. A sealing block 33 is provided on the top of the rear water barrier, which is used to guide the water flow from the lower guide channel 24 to the drain channel 29. Due to the complex shape of the cab side wall in the drainage section 28 area, in order to simplify the structural design of this drainage section 28, the embodiment of the application provides a sealing block 33 on the top of the rear water barrier, which is used to guide the water flow from the lower guide channel 24 to the drain channel 29.
[0046] A second aspect of this application provides a vehicle comprising a commercial vehicle cab with integrated drainage and a front-view mirror as described in any of the above embodiments.
[0047] Working principle This application provides a commercial vehicle cab and vehicle with integrated drainage and a front lower view mirror. The commercial vehicle cab with integrated drainage and a front lower view mirror of this application is provided with a cab body 10, which includes a cab side wall and a cab door 14. The outer wall of the cab side wall is provided with a rainwater guide channel 13 located above the cab door 14. The rainwater guide channel 13 extends from the rear wall of the cab body 10 to the A-pillar 16 of the cab body 10. The front lower view mirror 20 includes a front lower view mirror support 21. The front lower view mirror support 21 includes a guide section 22 and a drainage section 28 connected to each other. The guide section 22 is fixed in the rainwater guide channel 13 and together forms an upper guide channel 23 and a lower guide channel 24 that are separated from each other. The drainage section 28 is fixed on the A-pillar 16 and together forms a drain channel 29 that connects the upper guide channel 23 and the lower guide channel 24.
[0048] The commercial vehicle cab of this application, which integrates drainage and a front downward-facing mirror, has a rainwater guide channel 13 located above the cab door 14 on the outer wall of the cab side panel. The rainwater guide channel 13 extends from the rear panel of the cab body 10 to the A-pillar 16 of the cab body 10. A portion of the rainwater on the top of the cab side is guided into the rainwater guide channel 13 above the cab door 14, preventing a large amount of rainwater from flowing onto the door glass. This allows the driver to easily observe the front downward-facing mirror 20 and the rearview mirror 15 from inside the cab, even in rainy weather, thus improving driving safety.
[0049] In addition, the guide section 22 of the front lower mirror 20 is fixed in the rainwater guide channel 13 and together they form an upper guide channel 23 and a lower guide channel 24 that are separated from each other. Another part of the rainwater on the top of the side of the cab is guided into the upper guide channel 23 above the cab door 14, preventing a large amount of rainwater from flowing onto the door glass. After entering the lower guide channel 24, the rainwater in the rainwater guide channel 13 and the rainwater in the upper guide channel 23 enter the drain channel 29 together. The rainwater discharged from the drain channel 29 is discharged down the A-pillar 16 to the ground.
[0050] The guide section 22 of the front lower view mirror 20 can not only be installed in the rainwater guide channel 13, but also form the upper guide channel 23 and the lower guide channel 24 together with the rainwater guide channel 13. This provides an installation position for the front lower view mirror 20 on the side wall of the cab without affecting the normal drainage of the rainwater guide channel 13. The drainage section 28 is fixed to the A-pillar 16, and the guide section 22 is fixed in the rainwater guide channel 13. This makes the installation points of the front lower view mirror support 21 on the cab more dispersed. This not only reduces the stress on the front lower view mirror support 21 and the cab installation point, but also allows the rainwater discharged from the drain channel 29 to flow down the A-pillar 16, preventing the rainwater discharged from the drain channel 29 from flowing towards the door glass while the vehicle is in motion.
