Description

Technical Field

[0001] This utility model belongs to the field of rail transit vehicle technology, and more specifically, it relates to a door sill structure for a straddle-type monorail vehicle. Background Technology

[0002] The outer surface of the door sill of monorail vehicles is easily scratched and dented, requiring frequent replacement. Disassembling the sill is extremely inconvenient. The interlocking structure of the sill and its mounting bracket means that after the sill is pulled out a short distance, it must be lifted upwards to be fully removed. Furthermore, the length of the sill in the opening direction exceeds the door opening width, requiring the sill to be tilted to one side to be removed from the door stop. This necessitates the simultaneous removal of adjacent components (door edge trim, baseboard, side panel) to completely detach the sill from the vehicle body. This disassembly process is time-consuming, labor-intensive, and can damage other components.

[0003] Existing technology includes a sill assembly titled "A Sill Assembly for a Rail Vehicle Door System," with publication number CN216546165U. This technology discloses a sill assembly for a rail vehicle door system, comprising a sill and a sill base connected to the bottom of the sill. The sill base is connected to the vehicle body via a sill base mounting bracket. Multiple oblong holes for mounting screws are provided on the bottom surface of the sill and the top surface of the sill base mounting bracket. Multiple nut mounting grooves for accommodating nuts are provided on the bottom surface of the sill. The sill and the sill base mounting bracket are connected to the nuts in the nut mounting grooves via screws. The sill assembly can be adjusted forward and backward within the length of the oblong holes. Multiple gap compensation shims are provided on the mating end face of the sill base and the platform to eliminate the gap between the sill assembly and the platform. This invention can reduce the gap between the sill and the platform and allows for position adjustment, facilitating installation and maintenance.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a straddle-type monorail vehicle door sill structure that is simple in structure, can realize the outer sill being pulled out directly in the direction of the door without disassembling surrounding parts, and saves time and material costs in disassembly, in order to overcome the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a door sill structure for a straddle-type monorail vehicle. The lower surface of the body of the outer sill is provided with a positioning cavity, one side of the lower surface of the outer sill is provided with a positioning slot, and the other side of the lower surface of the outer sill is provided with a connecting plate. The sill mounting base includes a body surface and a folded edge, and the folded edge has an inverted L-shaped structure.

[0007] The outer sill body, positioning cavity, and connecting plate are an integral structure.

[0008] The main body and the folded edge of the threshold mounting base are an integral structure.

[0009] The sill mounting bracket is fixedly connected to the lower structural components of the vehicle body by screws.

[0010] The outer sill is configured to be fixedly connected to the sill mounting base. When the outer sill is fixedly connected to the sill mounting base, the positioning slot engages with the folded edge, and the positioning cavity abuts against the surface of the body.

[0011] Both the outer sill and the sill mounting base are elongated structures.

[0012] The outer door sill is provided with screw holes at both ends, and screws pass through the screw holes to fix the two ends of the outer door sill to the bottom of the door.

[0013] When the outer sill is fixedly connected to the sill mounting base, the connecting plate is fixedly connected to the lower structural component of the vehicle body by screws.

[0014] The upper surface of the main body is provided with multiple raised strips.

[0015] The working principle and beneficial effects of this utility model are as follows: The straddle-type monorail vehicle door sill structure of this utility model is constructed by separately manufacturing an outer sill and a sill mounting base. A positioning cavity is provided on the lower surface of the body of the outer sill. When the outer sill is installed in place, the positioning cavity abuts against the upper surface of the sill mounting base to ensure reliable support for the outer sill. A positioning slot is provided on one side of the lower surface of the outer sill, and a connecting plate is provided on the other side of the lower surface of the outer sill. The connecting plate is used to connect with the lower structural components of the vehicle body to ensure reliable connection on the side of the outer sill. The sill mounting base includes a body surface and a folded edge. The folded edge has an inverted L-shaped structure. When the outer sill is installed in place, the positioning slot engages with the folded edge, achieving abutment positioning of the inner side of the outer sill and the sill mounting base. When disassembling the outer threshold, simply remove the sealant around the threshold and take out the side screws. Then, pull the threshold outwards to complete the disassembly. To install a new outer threshold, simply push it inwards so that the positioning groove of the threshold engages with the folded edge of the threshold mounting base. The positioning cavity rests against the upper surface of the threshold mounting base. Then, secure it with screws on the side and apply sealant around the threshold. The disassembly and installation process is extremely convenient and quick, effectively saving costs. Attached Figure Description

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 Appendix Figure 2As shown, this utility model is a door sill structure for a straddle-type monorail vehicle. The lower surface of the body portion 8 of the outer sill 1 is provided with a positioning cavity 2, one side of the lower surface of the outer sill 1 is provided with a positioning groove 3, and the other side of the lower surface of the outer sill 1 is provided with a connecting plate 4. The sill mounting base 5 includes a body surface 6 and a folded edge portion 7, the folded edge portion 7 having an inverted L-shaped structure. The above structure addresses the shortcomings of the prior art and proposes an improved technical solution. During structural design, an outer sill 1 and a sill mounting base 5 are fabricated separately. The sill mounting base 5 is a component installed on the vehicle body. A positioning cavity 2 is provided on the lower surface of the body part 8 of the outer sill 1. When the outer sill is installed in place, the positioning cavity 2 abuts against the upper surface of the sill mounting base 5 to ensure that the outer sill 1 is reliably supported. A positioning slot 3 is provided on one side of the lower surface of the outer sill 1, and a connecting plate 4 is provided on the other side of the lower surface of the outer sill 1. The connecting plate 4 is used to connect with the lower structural component 10 of the vehicle body to ensure that the side of the outer sill 1 is reliably connected. The sill mounting base 5 includes a body surface 6 and a folded edge 7. The folded edge 7 has an inverted L-shaped structure. When the outer sill 1 is installed in place, the positioning slot 3 engages with the folded edge 7 to achieve abutment positioning of the inner sides of the outer sill 1 and the sill mounting base 5. When disassembling the outer sill 1, simply remove the sealant around the outer sill 1 and take out the side screws. Then, the outer sill 1 can be pulled directly outwards to complete the disassembly. Installing a new outer sill 1 is also straightforward; simply push it inwards. The positioning groove 3 of the outer sill 1 engages with the folded edge of the sill mounting base 5, the positioning cavity 2 rests against the upper surface of the sill mounting base 5, and then the side screws are used for fixing. Finally, sealant is applied around the outer sill 1 to complete the installation. The disassembly and installation of the outer sill 1 are extremely convenient and quick, reducing disassembly and installation difficulty, saving maintenance time, and reducing costs. The straddle-type monorail vehicle door sill structure described in this utility model has a simple structure, allowing the outer sill to be pulled directly outwards without disassembling surrounding components, saving time and material costs.

[0018] The outer sill 1 has a body 8, a positioning cavity 2, and a connecting plate 4, all of which are integrally formed. This structure allows the outer sill 1 to be integrally machined, resulting in a simple manufacturing process and good structural strength. Similarly, the sill mounting base 5 has a body surface 6 and a folded edge 7, both of which are integrally formed, resulting in a simple manufacturing process and good structural strength.

[0019] The sill mounting bracket 5 is fixedly connected to the lower structural component 10 of the vehicle body by screws 9. In this structure, the sill mounting bracket 5 can be reliably fixed using multiple screws.

[0020] The outer sill 1 is configured to securely connect to the sill mounting base 5. When the outer sill 1 is securely connected to the sill mounting base 5, the positioning slot 3 engages with the folded edge 7, and the positioning cavity 2 abuts against the upper surface of the body surface 6. When the outer sill 1 is securely connected to the sill mounting base 5, the connecting plate 4 is fixedly connected to the lower structural component 10 of the vehicle body via screws 9. In this structure, the outer sill is detachable, facilitating engagement and screw fixing with the sill mounting base 5. This ensures that the sill meets vehicle usage requirements after installation, preventing easy loosening, while allowing for quick and easy disassembly.

[0021] Both the outer sill 1 and the sill mounting base 5 are elongated structures. In this structure, the lengths of the outer sill 1 and the sill mounting base 5 are set according to the width of the vehicle door. The connecting plate 4 of the outer sill has multiple screw holes along its extended length, and each screw hole passes through a screw 9 to connect to the lower structural component 10 of the vehicle body. The sill mounting base 5 also has multiple screw holes along its extended length, and each screw hole passes through a screw 9 to connect to the lower structural component 10 of the vehicle body, ensuring a reliable and secure connection.

[0022] The outer sill 1 has screw holes at both ends, and screws pass through these screw holes to fix both ends of the outer sill 1 to the bottom of the door. This structure, using screws to fix the two ends of the outer sill 1, further improves the reliability of the outer sill 1 connection.

[0023] The upper surface of the main body 8 is provided with multiple raised strips 11. This structure, with its multiple raised strips 11, creates a textured surface on the upper surface of the outer sill, increasing friction and improving slip resistance.

[0024] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
