Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vehicle entrances and exits with movable or detachable covers, and particularly to an inspection port cover, an inspection port cover installation structure, and a vehicle. Background Technology
[0002] With the rapid development of my country's bus market, a large number of buses, passenger buses, and tour buses have been put into use. During the manufacturing process of these types of vehicles, inspection ports are opened on the vehicle body to facilitate the repair and replacement of internal parts. After being assembled into a complete vehicle, the inspection ports are usually located in the aisle of the passenger compartment. During daily operation, inspection port covers are installed at the inspection ports to prevent dust from falling into the internal parts of the vehicle and causing malfunctions, while also facilitating the movement of passengers in the passenger compartment. When a bus malfunctions, maintenance personnel can open the inspection port cover to repair the internal parts of the vehicle through the inspection port. However, because the engine noise is relatively high during vehicle operation, the noise can easily enter the passenger compartment through the inspection port, causing inconvenience to passengers.
[0003] To address the aforementioned issues, Chinese utility model patent CN213008415U, with an authorization announcement date of April 20, 2021, discloses a double-layer sealed, double-layer heat-insulating and noise-reducing inspection cover assembly for buses. This inspection cover assembly includes an inspection cover plate assembly and a bottom frame aluminum profile. A second heat-insulating and noise-reducing layer is provided below the inspection cover plate assembly. The inspection cover plate assembly is pressed downwards, and the second heat-insulating and noise-reducing layer is connected to the bottom frame aluminum profile by fastening bolts. The inspection cover plate assembly includes an upper cover. The first heat insulation and noise reduction layer is bonded to the lower surface of the upper cover plate. A bubble-sealed strip is set at the lower part of the bottom frame aluminum profile. The second heat insulation and noise reduction layer squeezes the bubble-sealed strip to partially compress and deform it to form the first seal. There are two semi-circular protrusions on the lower support surface of the bottom frame aluminum profile. The second heat insulation and noise reduction layer will deform at the semi-circular protrusions due to the force to form the second seal. The double-layer seal and double-layer heat insulation and noise reduction structure can better play the role of sealing, heat insulation and noise reduction, and improve the passenger riding experience.
[0004] In the above solution, the inspection cover assembly also includes decorative cover aluminum profiles. Currently, the existing decorative cover aluminum profiles are all located between the upper cover and the car floor. The side of the decorative cover aluminum profile closest to the car floor has a floor edging, and the side closest to the upper cover has a cover edging. The upper cover is flush with the car floor, but both the floor edging and the cover edging protrude from the upper surface of the car floor and the upper cover. This makes it inconvenient to clean and can easily cause passengers to trip and fall while walking. Utility Model Content

Detailed Implementation
[0043] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0044] This invention addresses the problem that when existing inspection covers are installed on inspection hatches inside the passenger compartment, the profile frame between the inspection cover and the passenger compartment floor protrudes, causing passengers to trip and fall. By setting recessed structures on both the inspection hatch cover and the passenger compartment floor, the profile frame is installed within these recessed structures, achieving a flush alignment between the profile frame and both the inspection hatch cover and the passenger compartment floor, allowing passengers to walk freely within the passenger compartment. Based on this inventive concept, this invention proposes an inspection hatch cover, its installation structure, and a vehicle. By setting a recessed structure at the edge of the hatch body where the inner flange of the outer frame overlaps, and also at the inspection hatch where the outer flange of the outer frame overlaps, the inner and outer flanges of the outer frame overlap within the corresponding recessed structures, thus achieving the recessed design of the outer frame and ensuring its flush alignment with the vehicle floor and the hatch body.
[0045] The implementation method of the inspection port cover of this utility model is as follows:
[0046] See Figure 1 As a basic embodiment of this utility model, the inspection hatch includes a hatch body 1 and an outer frame 2 located at the edge of the hatch body 1. In actual engineering applications, the hatch body 1 is usually rectangular. The outer frame 2 at the four edges of the hatch body 1 is formed by two U-shaped frames joined together to form a rectangular outer frame 2, or by a U-shaped frame and a straight edge sealing to form a rectangular outer frame 2. The upper surface of the hatch body 1 is a planar structure. The edge of the hatch body 1 where the pressing edge 3 of the outer frame 2 is placed is a recessed structure, so that after the pressing edge 3 of the outer frame 2 is placed on the edge of the hatch body 1, the top of the outer frame 2 is flush with the upper surface of the hatch body 1. This setting can realize the recessed design of the outer frame 2, so that the top of the outer frame 2 is flush with the upper surface of the hatch body 1, forming an inspection hatch with a flush upper surface. In specific use, the inspection hatch with a flush upper surface is installed in the inspection hatch 13 of the vehicle, which can ensure that passengers can walk freely in the carriage without tripping, and also facilitate the cleaning of the carriage by the staff.
[0047] As a preferred embodiment of this utility model, such as Figure 1 As shown, the sunken structure is a downward slope 4 from the inside out. The lower side of the pressing edge 3 of the outer frame 2 is a downward pressing slope 5 adapted to the downward slope 4. In this embodiment, the four edges of the cap body 1 are provided with a downward slope 4 extending from the inside to the outside as a sunken structure. The pressing edge 3 of the outer frame 2 overlaps on the downward slope 4, so that the downward pressing slope 5 is parallel and attached to the downward slope 4, so that the upper surface of the cap body 1 is completely flush with the upper surface of the outer frame 2.
[0048] Based on the above embodiments, as a preferred embodiment of this utility model, the sinking structure is a sinking groove, the depth of which is equal to the maximum thickness of the pressing edge 3. The sinking groove extends along the thickness direction of the cap body 1. At this time, the pressing edge 3 of the outer frame 2 sinks down and overlaps in the sinking groove, so that the upper surface of the outer frame 2 is flush with the upper surface of the cap body 1. In this embodiment, when the lower side of the pressing edge 3 is the aforementioned pressing slope 5, it is sufficient to ensure that the maximum thickness of the pressing edge 3 is equal to the depth of the sinking groove to achieve flushing. In other embodiments, the lower side of the pressing edge 3 can also be set as a plane. In this case, the thickness of each part of the pressing edge 3 is consistent, and it is sufficient to ensure that the thickness of the pressing edge 3 is equal to the depth of the sinking groove to achieve flushing. In addition, in this embodiment, sinking grooves are provided as sinking structures on all four edges of the cap body 1, and the pressing edge 3 of the outer frame 2 can directly sink down and overlap in the sinking groove.
[0049] Based on the above embodiments, as a preferred embodiment of this utility model, the upper surface of the outer frame 2 is made flat, so that the upper surface of the outer frame 2 is completely flush with the upper surface of the cover body 1, further improving the comfort and flatness of passenger walking. In other embodiments, the upper surface of the outer frame 2 can also be made into an arc surface, and the arc surface of the outer frame 2 is also recessed into the recessed structure. In this case, it is sufficient to ensure that the horizontal plane where the highest point of the arc surface is located is flush with the upper surface of the cover body 1. The arc surface can disperse the stress on the outer frame 2, improve the service life of the outer frame 2, and at the same time, the arc surface will not create steps and will not cause passengers to trip and fall.
[0050] In a preferred embodiment of this utility model, the outer frame 2 is a profile frame. The profile has good structural strength, can withstand long-term pressure, and will not easily deform. The profile frame includes vertically extending side walls 6 and a bidirectional flange at the top of the side walls 6. The inward flange constitutes the pressing edge 3, and the outward flange is used to rest on the edge of the inspection port 13. The bottom of the side walls 6 is provided with an inwardly extending lower retaining edge 7. The cover body 1 is held between the pressing edge 3 and the lower retaining edge 7. The pressing edge 3, the side walls 6, and the lower retaining edge 7 are integrally formed to constitute the profile frame, which can provide strong support for the cover body 1 and has good connection reliability. In other embodiments, the outer frame 2 can also be set as an integrally formed T-shaped frame. The crossbeam of the T-shaped frame constitutes the pressing edge 3, and the longitudinal beam of the T-shaped frame constitutes the side walls 6. The retaining edge is connected to the lower end of the T-shaped frame through a connector. The cover body 1 is engaged through the retaining edge and the pressing edge 3. The outer frame 2 configured in this way also has high strength.
[0051] In a preferred embodiment of this utility model, the cover body 1 includes a cover floor 8 and a floor covering 9 laid thereon. The floor covering 9 is sandwiched between the pressing edge 3 and the cover floor 8. The floor covering 9 will sink down with the sinking structure. When the outer frame 2 is engaged with the cover body 1, the pressing edge 3 of the outer frame 2 overlaps the floor covering 9 above the sinking structure so that the upper surface of the outer frame 2 is flush with the upper surface of the floor covering 9. The floor covering 9 can prevent passengers from slipping and falling while walking. The flush arrangement of the upper surface of the outer frame 2 with the upper surface of the floor covering 9 can allow passengers to walk freely in the carriage without tripping.
[0052] In a preferred embodiment of this utility model, in practical engineering applications, vehicles typically generate significant noise. Therefore, the access cover also includes a bottom cover 10, which is connected to the bottom of the outer frame 2. A noise-reducing layer 11 is filled between the bottom cover 10 and the access cover body 1. The noise-reducing layer 11 isolates the noise source, preventing noise from being transmitted into the passenger compartment and affecting the passenger's riding experience. The bottom cover 10 provides good structural strength for the noise-reducing layer 11 and the access cover body 1. The bottom cover 10 is fixedly connected to the outer frame 2. Here, the bottom cover 10 can be connected to the outer frame 2 by welding or by fasteners such as bolts, as long as the reliability of the connection between the bottom cover 10 and the outer frame 2 is ensured. In other embodiments, if there is no noise source under the floor, the noise-reducing layer 11 is omitted to reduce the weight of the access cover.
[0053] The installation process of the inspection port cover assembly of this utility model is as follows: The cover body 1 connected with the floor covering 9 is snapped into the outer frame 2. During the snapping process, the pressing edge 3 of the outer frame 2 will overlap the upper surface of the slope 4 or the sinkhole. At this time, the upper surface of the outer frame 2 is flush with the upper surface of the floor covering 9, forming a flush inspection port cover. Finally, the flush inspection port cover is installed at the vehicle's inspection port 13.
[0054] Implementation method of the inspection port cover installation structure of this utility model:
[0055] See Figure 1As a basic embodiment of this utility model, the inspection port cover installation structure includes a vehicle floor 12 and an inspection port 13 disposed on the floor. An inspection port cover is installed at the inspection port 13. The inspection port cover includes a cover body 1 and an outer frame 2 located at the edge of the cover body 1. The outer frame 2 of the inspection port cover has an outer flange 14. The upper surface of the inspection port cover is generally planar. The edge of the inspection port 13 where the outer flange 14 rests is recessed, so that when the inspection port cover is fastened to the inspection port 13, the upper surface of the floor is flush with the upper surface of the inspection port cover. This embodiment utilizes the outer flange 14 to achieve this. The upper surface of the frame 2 is flush with the upper surface of the cover body 1. At the same time, the edge of the inspection port 13 where the outer flange 14 of the outer frame 2 overlaps is set as a recessed structure. This achieves a design where the upper surface of the vehicle floor 12 is flush with the upper surface of the inspection port cover when the inspection port cover is installed inside the inspection port 13. In addition, the upper surface of the inspection port cover itself is also flush. In actual use, the inspection port cover is installed inside the inspection port 13. At this time, the outer frame 2 is flush with both the cover body 1 and the vehicle floor 12, which can ensure that passengers can walk freely in the carriage without tripping.
[0056] As a preferred embodiment of the present invention, the sunken structure is a sloping surface that slopes from the inside out, and the lower side of the outer flange 14 is an overlapping slope 16 adapted to the sloping surface. When the outer flange 14 of the outer frame 2 overlaps above the sunken structure at the edge of the access port 13, the overlapping slope 16 is parallel and fits against the sloping surface. At this time, the outer frame 2 is flush with the access port 13, that is, the access port cover is flush with the vehicle floor 12.
[0057] Based on the above embodiments, as a preferred embodiment of this utility model, the sunken structure is a sunken overlapping groove 15. The depth of the sunken overlapping groove 15 is equal to the maximum thickness of the outer flange 14. When the outer flange 14 of the outer frame 2 overlaps in the sunken overlapping groove 15 at the edge of the inspection port 13, the outer frame 2 is flush with the inspection port 13, that is, the inspection port cover is flush with the vehicle floor 12. In this embodiment, when the lower side of the outer flange 14 is the aforementioned overlapping slope 16, ensuring that the maximum thickness of the outer flange 14 is equal to the groove depth of the sunken overlapping groove 15 is sufficient to achieve flushing. In other embodiments, the lower side of the outer flange 14 can also be set as a plane. In this case, the thickness of each part of the outer flange 14 is consistent, and ensuring that the thickness of the outer flange 14 is equal to the groove depth of the sunken overlapping groove 15 is sufficient to achieve flushing.
[0058] Based on the above embodiments, as a preferred embodiment of this utility model, such as Figure 1 As shown, the sunken structure is set as a sunken overlapping groove 15, and the lower side of the outer flange 14 is set as an overlapping slope 16, so that the outer flange 14 sinks and overlaps in the sunken overlapping groove 15. The overlapping slope 16 will partially contact the sunken overlapping groove 15. At this time, ensuring that the maximum thickness of the outer flange 14 with the overlapping slope 16 is equal to the groove depth of the sunken overlapping groove 15 can achieve flushing.
[0059] As a preferred embodiment of the present invention, the vehicle floor 12 includes a floor body 17 and a floor covering 9 laid thereon. The floor covering 9 is sandwiched between the outer flange 14 and the floor body 17. The floor covering 9 will sink along with the sinking structure. When the outer flange 14 of the outer frame 2 overlaps the sinking overlap groove 15 or the slope surface, the upper surface of the outer frame 2 is flush with the upper surface of the floor covering 9.
[0060] In a preferred embodiment of this utility model, the inspection port cover is selected from the inspection port cover described above. The outer frame 2 of the inspection port cover is recessed and overlapped on the cover body 1 to achieve a flush arrangement between the inspection port cover and the vehicle floor 12. In other embodiments, the outer frame 2 can also be set as a Z-shaped frame, so that the cover body 1 is placed on the lower horizontal side of the Z-shaped frame, and the upper side of the cover body 1 is flush with the upper surface of the upper horizontal side of the Z-shaped frame. This also achieves a flush design of the inspection port cover itself. When the inspection port cover in this embodiment is installed in the inspection port, a flush design between the inspection port cover and the vehicle floor 12 can also be achieved.
[0061] The installation process of the inspection port cover installation structure of this utility model is as follows: First, a recessed overlapping groove 15 or a slope surface is set at the edge of the inspection port 13 on the floor body 17. Then, the floor covering 9 is glued or connected to the upper surface of the floor body 17 by other means. Subsequently, the flush inspection port cover is installed in the inspection port 13. During this installation process, the overlapping slope 16 of the outer frame 2 will overlap and fit with the floor covering 9 on the recessed overlapping groove 15 or slope surface. At this time, the upper surface of the outer frame 2 is flush with the upper surface of the floor covering 9 on the floor body 17, forming a flush design between the inspection port cover and the vehicle floor 12.
