Description

Technical Field

[0001] This utility model relates to the arrangement of pedals or ladders in a vehicle, and more particularly to a step floor strip, a vehicle step structure, and a vehicle. Background Technology

[0002] The aisle of the bus is equipped with steps on both sides for passengers to step into the seating area. Each step is equipped with a step strip, which is generally made of aluminum profile. The step strip has flooring inserted in the middle, or the step strip is punched with holes and a rubber pad is added as a step surface. Both of these step strips have an anti-slip function to prevent passengers from slipping and falling during boarding and alighting. However, there is no lighting on the step strips. When passengers board and alight at night, their vision is not clear, which makes them prone to tripping or misstepping, creating a safety hazard.

[0003] To address the aforementioned issues, Chinese utility model patent CN202038239U, with an authorization announcement date of November 16, 2011, discloses a step profile with LED lights for buses. This step profile is mounted above the square tube of the step frame of the vehicle. The step profile includes an aluminum profile body, which includes a horizontal pressing edge fixed to the plane of the square tube of the step frame and a side pressing edge fixed to the vertical surface of the square tube of the step frame. A groove is provided on the side pressing edge for mounting a light strip. The light emitted by the light strip will shine out from the opening of the groove to illuminate the passageway.

[0004] However, in the above scheme, the side pressing edge is thicker in order to install the light strip so that the groove can be opened. The thickness of the side pressing edge results in a greater distance between it and the vertical surface of the step frame square tube, forming a small protrusion. Passengers are prone to tripping and falling on the small protrusion when getting on and off the vehicle, which poses a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a step floor strip that addresses the problem of small protrusions formed between the side edges of existing step treads and the square tube of the step frame, which can easily cause passengers to trip and fall when getting on and off the vehicle. Furthermore, this utility model aims to provide a vehicle step structure that, by using the aforementioned step floor strip, solves the problem of existing step materials easily causing passengers to trip. Additionally, this utility model aims to provide a vehicle that, by using the aforementioned vehicle step structure, solves the safety hazard posed by existing step materials easily causing passengers to trip.

[0006] To achieve the above objectives, the step floor molding strip of this utility model adopts the following technical solution:

[0007] A type of step floor strip, which is a profile strip, includes a flat edge for fixing to the step floor and a vertical edge for pressing onto the step facade. The vertical edge is connected to the flat edge through a corner connecting section. The corner connecting section is recessed relative to the step facade and forms an outwardly open light groove with the lower side of the flat edge. The lower part of the corner connecting section has an edge support portion that abuts against the edge of the step floor to be supported by the step floor. The outer edge of the flat edge is close to or flush with the outer side of the vertical edge to avoid tripping.

[0008] Furthermore, the corner connecting section is an obliquely placed L-shaped connecting section, and the light groove formed by the L-shaped connecting section and the lower side of the flat pressing edge is a U-shaped groove with the opening facing downwards at an angle.

[0009] Furthermore, the outer edge of the planar pressing edge is a rounded edge to prevent tripping.

[0010] Furthermore, there is a weight-reducing and reinforcing cavity between the rounded edge and the wall of the lamp trough.

[0011] Beneficial Effects: This utility model of a step floor strip is a pioneering invention. By fixing the flat edge to the upper surface of the step base plate on the step plane and by fastening the vertical edge to the vertical surface of the step, a reliable connection between the floor strip and the step is achieved. The corner connecting section and the lower side of the flat edge form an outward-opening light trough, which can be used to install light strips. The light from the light strips shines out from the outward opening, illuminating the aisle of the carriage and improving passenger visibility. Furthermore, the lower edge support of the corner connecting section can abut against the edge of the step plane, with the step plane providing support for the edge support, which in turn provides support for the outer edge of the flat edge, improving the stability of the floor strip. Simultaneously, by making the outer edge of the flat edge close to or flush with the outer side of the vertical edge, the outer end of the floor strip is placed on the same vertical plane, preventing small protrusions and avoiding tripping and falls during passenger boarding and alighting, thus improving safety.

[0012] The vehicle step structure of this utility model adopts the following technical solution:

[0013] The vehicle step structure includes step steps and step floor strips installed at the corners of the step steps. The step steps include a step plane and a step elevation. The step plane is covered with step floor, and a reserved gap is left between the edge of the step floor and the step elevation. The step floor strip is a profile strip, including a flat edge for fixing to the step floor and a vertical edge for pressing against the step elevation. The vertical edge is connected to the flat edge through a corner connecting section. The corner connecting section is recessed inward relative to the step elevation within the reserved gap and forms an outwardly open light trough with the lower side of the flat edge. The lower part of the corner connecting section has an edge support part for abutting against the edge of the step plane to be supported by the step plane. The outer edge of the flat edge is close to or flush with the outer side of the vertical edge to avoid tripping.

[0014] Furthermore, a wiring channel is formed between the stepped floor and the corner connecting section.

[0015] Furthermore, the corner connecting section is an obliquely placed L-shaped connecting section, and the light groove formed by the L-shaped connecting section and the lower side of the flat pressing edge is a U-shaped groove with the opening facing downwards at an angle.

[0016] Furthermore, the outer edge of the planar pressing edge is a rounded edge to prevent tripping.

[0017] Furthermore, there is a weight-reducing and reinforcing cavity between the rounded edge and the wall of the lamp trough.

[0018] Beneficial Effects: This utility model's vehicle step structure is a pioneering invention. By setting a reserved gap between the edge of the step floor and the step facade, the floor strip, when installed on the step base plate, has space to accommodate the recessed portion of the corner connector, thus reducing the overall space occupied by the step structure. Simultaneously, the abutment between the edge support and the edge of the step plane ensures a reliable connection between the floor strip and the step, guaranteeing the stability of the floor strip. LED strips can be installed in the light trough to illuminate the aisle. Furthermore, by making the outer edge of the planar edge close to or flush with the outer side of the facade edge, the outer end of the floor strip is placed on the same vertical plane, preventing small protrusions and avoiding tripping and falls during passenger boarding and alighting, thus improving safety.

The lower part of the corner connecting section has an edge support part for abutting against the edge of the step plane to be supported by the step plane. The outer edge of the flat edge is close to or flush with the outer side of the vertical edge to avoid tripping.

[0021] Furthermore, a wiring channel is formed between the stepped floor and the corner connecting section.

[0022] Furthermore, the corner connecting section is an obliquely placed L-shaped connecting section, and the light groove formed by the L-shaped connecting section and the lower side of the flat pressing edge is a U-shaped groove with the opening facing downwards at an angle.

[0023] Furthermore, the outer edge of the planar pressing edge is a rounded edge to prevent tripping.

[0029] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] This invention addresses the problem of small protrusions on existing step strips that can easily trip passengers. By setting the outer ends of the planar and vertical edges of the step strip to be nearly or flush, the formation of small protrusions is avoided, thus preventing passengers from tripping. Based on the above inventive concept, this invention proposes a step floor strip, a vehicle step structure, and a vehicle. A corner connecting section connects the planar and vertical edges, and by making the outer ends of the planar and vertical edges nearly or flush, the formation of small protrusions in the step structure is avoided, thus preventing passengers from tripping.

[0031] The embodiment of the step floor molding strip of this utility model:

[0032] See Figure 1 As a basic embodiment of this utility model, the step floor strip is a profile strip. The profile strip has good structural strength and will not easily deform. The profile strip includes a flat edge 1 for fixing to the step floor 13 on the step plane 11 and a vertical edge 2 for pressing onto the step facade 12. The flat edge 1 and the vertical edge 2 work together to achieve a reliable connection between the floor strip and the step, avoiding displacement of the step floor strip under long-term foot traffic when fixed at a single point. The vertical edge 2 is connected to the flat edge 1 through a corner connecting section 3. In specific use, the corner connecting section 3 is located at the corner of the step plane 11 and the step facade 12, hence it is called the corner connecting section 3. The corner connecting section 3 is concave relative to the step facade 12 and is flush with the flat edge 12. The lower side of the surface edge 1 forms an outward-opening light trough 4, which can be used to install a light strip 16. The light from the light strip 16 will shine out from the outward opening, illuminating the aisle of the carriage and making the passengers' vision clearer. The lower part of the corner connecting section 3 has an edge support part 5 for the edge of the step plane 11 to abut against and be supported by the step plane 11. The step plane 11 provides support for the edge support part 5, which in turn provides support for the outer edge of the surface edge 1, which can improve the stability of the floor strip. The outer edge of the surface edge 1 is close to or flush with the outer side of the vertical edge 2 to avoid tripping. At this time, the outer end of the floor strip is on the same vertical plane and will not produce a small protrusion, avoiding tripping and falling injuries to passengers during getting on and off the vehicle, thus improving safety.

[0033] In a preferred embodiment of this utility model, the corner connecting section 3 is an obliquely placed L-shaped connecting section. The light groove 4 formed by the L-shaped connecting section and the lower side of the flat pressing edge 1 is a U-shaped groove with the opening tilted downwards. The light strip 16 is installed in the U-shaped groove, so that the light from the light strip 16 is emitted from the opening at a downward tilt, illuminating the aisle of the carriage. In other embodiments, the corner connecting section 3 can also be set as an arc-shaped connecting section, so that the lower end of the arc-shaped connecting section abuts against the corner of the step plane 11 and the step elevation 12. The arc-shaped connecting section can also form a light groove 4 with a downwardly tilted opening with the lower side of the flat pressing edge 1 for the installation of the light strip 16.

[0034] In a preferred embodiment of this invention, the outer edge of the flat pressing edge 1 is rounded 6 to prevent tripping. During passenger boarding and alighting, the center of the passenger's foot makes the most contact with this rounded edge 6. This rounded edge 6 increases the contact area between the passenger's foot and the flat pressing edge 1, thus preventing foot discomfort and improving passenger comfort. Simultaneously, the rounded edge 6 disperses stress, and the stress distribution at each point on the rounded edge 6 is uniform, preventing easy deformation. In other embodiments, the outer edge of the flat pressing edge 1 can also be chamfered, i.e., the outer edge of the flat pressing edge 1 is a bevel, which also increases the contact area with the foot and prevents foot discomfort.

[0035] In a preferred embodiment of this invention, a weight-reducing and reinforcing cavity 7 is provided between the rounded edge 6 and the wall of the light groove 4. This arrangement reduces the weight of the flat edge 1, thereby reducing the overall weight of the step floor strip and contributing to the overall weight reduction of the vehicle. While reducing weight, the strength of the flat edge 1 is increased, its resistance to deformation is improved, and its service life is extended. In other embodiments, the space between the rounded edge 6 and the wall of the light groove 4 can also be made into a solid structure, capable of withstanding prolonged foot traffic without deformation.

[0036] In a preferred embodiment of this utility model, the facade pressing edge 2 is an arched pressing edge, which arches outward in the direction away from the step facade 12. In other embodiments, the facade pressing edge 2 can also be set as a broken line pressing edge, which includes a straight pressing edge and an inward pressing edge. The two ends of the straight pressing edge are respectively connected to the edge support part 5 of the corner connecting section 3 and the inward pressing edge. The inward pressing edge is used to press onto the step facade 12 to achieve a reliable connection with the step facade.

[0037] In a preferred embodiment of this utility model, the flat edge 1 is provided with a through-hole 8 for inserting the floor covering 9. After the flat edge 1 is fixed to the upper surface of the step base plate, the floor covering 9 is inserted into the through-hole 8. The floor covering 9 will cover the fixed position of the flat edge 1 and the step base plate. At the same time, the upper surface of the floor covering 9 will be flush with the upper surface of the flat edge 1. When passengers get on and off the vehicle, they will step on the floor covering 9, which is more comfortable and can also prevent slipping, thus improving the safety of passengers getting on and off the vehicle.

[0038] The installation and use process of the step strip structure of this utility model is as follows: First, the light strip 16 is fixedly installed in the light groove 4 by adhesive or bolt. Then, the step floor strip, which is integrally formed or welded into a whole, is installed on the step, so that the flat edge 1 and the vertical edge 2 are fixed on the upper surface of the step bottom plate and the vertical surface 12 of the step at the same time, so that the step floor strip is reliably connected to the step. Then, the floor covering 9 is inserted into the through groove 8 to complete the installation. When in use, passengers will step on the arc edge and the floor covering 9 during the process of getting on and off the vehicle, which can prevent foot pain and also prevent slipping. The light strip 16 on the step floor strip will illuminate the aisle of the carriage, making the passengers' vision clearer.

[0039] Implementation method of the vehicle step structure of this utility model:

[0040] See Figure 2 The vehicle step structure includes a step 10 and a step floor strip installed at the corner of the step 10. The step 10 includes a step plane 11 and a step elevation 12. A step floor 13 is laid on the step plane 11, and a reserved gap 14 is left between the edge of the step floor 13 and the step elevation 12. The step floor strip is the step floor strip in the above embodiment, and its structure will not be described in detail here.

[0041] In practical use, the flat edge 1 of the step floor strip is fixed to the upper surface of the step floor 13, and the vertical edge 2 is pressed onto the vertical surface 12 of the step, so that the step floor strip and the step 10 form a reliable connection. There is a gap between the vertical edge 2 and the vertical surface 12 of the step, which is used to accommodate the floor covering 9 adhered to the vertical surface 12 of the step. The vertical edge 2 is pressed and fixed onto the floor covering 9. At this time, the concave part of the corner connecting section 3 is located within the reserved gap 14, which can reduce the overall space occupied by the step structure. At the same time, the edge support 5 of the corner connecting section 3 presses against the edge of the step plane 11, which can support the corner connecting section 3 with the help of the step, thereby supporting the flat edge 1 and preventing the flat edge 1 from deforming under long-term footing. In addition, the outer edge of the flat edge 1 is close to or flush with the outer side of the vertical edge 2, which can prevent passengers from tripping and falling during getting on and off the vehicle, thus improving safety.

[0042] Based on the above embodiments, a wiring channel 15 is formed between the stepped floor 13 and the corner connecting section 3. The wiring of the light strip 16 can be laid in the wiring channel 15 to form a hidden design, which is aesthetically pleasing and has a high space utilization rate.

[0043] The implementation method of the vehicle of this utility model:

[0044] The vehicle includes a carriage aisle, and vehicle step structures are provided on both sides of the carriage aisle. The vehicle step structures are the same as those in the above embodiments, and will not be described again here.
