Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a step ladder for a tractor unit. Background Technology

[0002] In today's transportation industry, tractor-trailers are widely used as key transport tools. To facilitate drivers and passengers in easily getting on and off the work platform above the chassis, enabling efficient trailer operations and a comprehensive view of the vehicle and trailer's condition, steps and handrails are usually provided between the ground and the work platform.

[0003] However, most current ladders and handrails on the market have certain limitations in design. They are mostly installed above battery boxes, which leads to a significant problem—due to the diverse forms of battery boxes, different types require specific ladders and handrails to match, making the related structures complex and lacking versatility. During installation, these ladders and handrails often rely heavily on pre-defined holes on the battery box for fixing, which not only increases the difficulty of installation but also makes the installation space extremely limited, severely restricting the possibility of independent expansion and development, and making it difficult to meet diverse practical application needs.

[0004] Meanwhile, the existing combination of steps and handrails also has some shortcomings. For example, its overall weight is relatively heavy, a drawback that is particularly prominent in the current pursuit of lightweight vehicles. Furthermore, the design pattern where boarding steps are mostly located on the battery box means that the type of battery box directly determines the structural form of the boarding steps. This one-to-one correspondence severely restricts the unified management and allocation of resources, increasing the complexity and cost of parts management for enterprises. Overall, while the existing boarding steps, composed of handrails and steps, meet basic functional requirements to a certain extent, there is still considerable room for improvement in terms of weight, cost, and compatibility with the vehicle to better adapt to the rapid development of the transportation industry and the ever-changing market demands. Summary of the Invention

[0005] In view of the problems existing in the prior art, this utility model provides a boarding ladder for a tractor, which simplifies the structure of the boarding ladder, improves the convenience of vehicle layout, and reduces costs and weight.

[0006] This utility model is implemented as follows: a boarding step for a tractor includes a horizontally arranged step, side plates are respectively provided on the end faces of both sides of the step, the side plates extend obliquely upward relative to the step, and the side plates away from the step connection side are bent towards the step mounting side to provide a transition part, the end of the transition part is bent inward to provide a mounting part parallel to the step mounting surface; an elongated hole is provided on the side plate along the axial direction of the side plate.

[0007] The parallel mounting section formed by bending allows for direct fixation to the frame longitudinal beams or other rigid structures, eliminating the need for holes or structures in the battery box. This solves the problem of installation limitations, enhances spatial adaptability, and overcomes the space constraints of the narrow battery box area. The elongated hole design on the side panels significantly reduces weight while maintaining strength. The side panels on both sides of the pedals extend diagonally upwards and connect to the step mounting surface through transition sections and mounting sections. This structural design allows the steps to better distribute stress when bearing the load of passengers getting on and off the vehicle, improving structural stability and reliability.

[0008] Furthermore, the upper surface of the pedal is evenly distributed with multiple anti-slip protrusions. These anti-slip protrusions, as a passive safety design, directly act on the foot contact surface, significantly reducing the risk of slipping and falling under wet, oily, or icy conditions. During the stamping process, the anti-slip protrusions enhance the local rigidity of the pedal, forming a micro-reinforcing rib effect, thus balancing anti-slip properties with load-bearing stability.

[0009] Furthermore, each anti-slip protrusion has a round hole stamped on its raised portion. Stamping the round hole reduces the amount of material used in the anti-slip protrusion, further reducing the weight of the pedal without compromising anti-slip performance, thus contributing to the overall weight reduction of the vehicle.

[0010] Furthermore, two elongated holes are provided, and the two elongated holes are equidistantly distributed along the axis of the side plate.

[0011] Furthermore, both the treads and side panels are formed by stamping and bending. The treads, side panels, transition sections, and mounting sections are integrally formed by sheet metal bending, eliminating the need for welded supports, independent handrails, and complex connecting parts found in traditional staircases, thus significantly reducing the number of parts.

[0012] The advantages and technical effects of this utility model are as follows: By adopting the above technical solution, the structure of the boarding stairs is simplified, which improves the convenience of the overall vehicle layout while reducing costs and weight. The stairs are designed as a single-step structure, and the treads are not only strong but also have excellent anti-slip performance, ensuring safety and reliability in use.

[0013] Abandoning the traditional combination of steps and independent handrails, the traditional handrails are eliminated. The boarding steps are positioned on the left rear side of the rear-mounted gas cylinder. This allows the oval lifting holes on the gas cylinder frame to serve as handrails, utilizing the vehicle's existing, stable system structure as a natural support point for the handrail, thus achieving a safe grip function. While meeting functional requirements, this design not only significantly simplifies the step body but also substantially reduces material and manufacturing costs. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1 and Figure 2 As shown, this application provides a boarding step for a tractor unit, including a horizontally arranged step 1. Side plates 2 are respectively provided on the end faces of both sides of the step 1. The side plates 2 extend obliquely upward relative to the step 1. A transition portion 2-1 is formed by bending the side plate 2 away from the connecting side of the step 1 towards the step mounting side. The end of the transition portion 2-1 is bent inward to form a mounting portion 2-2 parallel to the step mounting surface. Specifically, both the step 1 and the side plates 2 are formed by stamping and bending. The step 1, side plates 2, transition portion 2-1, and mounting portion 2-2 are integrally formed by sheet metal bending, eliminating the need for welded brackets, independent handrails, and complex connecting parts found in traditional steps, significantly reducing the number of parts.

[0020] The side plate 2 is provided with elongated holes 2-3 along the axial direction of the side plate 2. Preferably, there are two elongated holes 2-3, which are equidistantly distributed along the axial direction of the side plate 2.

[0021] The parallel mounting section 2-2, formed by bending, can be directly fixed to the longitudinal beam of the frame 5 or other rigid structures, without relying on the holes or structure of the battery box, thus solving the problem of installation limitations, enhancing spatial adaptability, and overcoming the narrow space limitations of the battery box area. The elongated hole 2-3 design on the side plate 2 significantly reduces weight while ensuring strength; the side plates 2 on both sides of the pedal 1 extend obliquely upward and are connected to the step mounting surface through the transition section 2-1 and the mounting section 2-2. This structural design allows the step to better distribute stress when bearing the load of people getting on and off the vehicle, improving the stability and reliability of the structure.

[0022] Furthermore, the upper surface of the pedal 1 is evenly distributed with multiple anti-slip protrusions 1-1. As a passive safety design, the anti-slip protrusions 1-1 directly act on the foot contact surface, significantly reducing the risk of slipping and falling under wet, oily, or icy conditions. During the stamping process, the anti-slip protrusions 1-1 enhance the local rigidity of the pedal 1, forming a micro-reinforcing rib effect, thus balancing anti-slip properties with load-bearing stability.

[0023] Preferably, each anti-slip protrusion 1-1 has a round hole stamped on its protrusion portion. Stamping the round hole can reduce the amount of material used in the anti-slip protrusion 1-1, further reducing the weight of the pedal 1 without reducing the anti-slip performance, thus contributing to the overall weight reduction of the vehicle.

[0024] By adopting the above technical solution, the structure of the boarding stairs is simplified, improving the convenience of overall vehicle layout while reducing costs and weight. The stairs are designed as a single-step structure, with pedal 1 not only having high strength but also excellent anti-slip performance, ensuring safety and reliability in use.

[0025] Abandoning the traditional combination of steps and independent handrails, the traditional handrails are eliminated. The boarding steps are positioned on the left rear side of the rear-mounted gas cylinder. This allows the oval gas cylinder mounting holes 4 on the cylinder frame to serve as handrails, utilizing the vehicle's existing, stable system structure as a natural support point for the handrail, thus achieving a safe grip function. While meeting functional requirements, this design not only significantly simplifies the step body but also substantially reduces material and manufacturing costs.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
