Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The following is for reference. Figures 1-4 A ladder assembly 10 according to an embodiment of the present invention includes: a connecting rod 100, a connecting portion 200, and a ladder portion 300.

[0029] Specifically, the connecting part 200 is located at one end of the connecting rod 100 and is used to connect to the frame; the step part 300 is connected to the other end of the connecting rod 100 and extends horizontally, and is used to support the user.

[0030] It should be noted that in existing technologies, the chassis of heavy-duty trucks is relatively high in structural design, making it difficult for users to move from the ground onto the chassis, which hinders subsequent installation or maintenance of the vehicle. Related technologies typically employ stepped step assemblies to assist users in moving from the ground onto the chassis for installation or maintenance. While these stepped step assemblies effectively assist users in moving, they are costly. Therefore, a step assembly 10 is proposed that effectively assists users in moving from the ground onto the chassis while possessing a simple structure and low production cost.

[0031] Specifically, the step assembly 10 in this application is adapted to include: a connecting rod 100, a connecting portion 200, and a step portion 300. One end of the connecting rod 100 is connected to the connecting portion 200, which is adapted to provide a large contact area for connecting to the frame, so as to make the assembly and use of the step assembly 10 more reliable. The other end of the connecting rod 100 is provided with a step portion 300, so that the step portion 300 is horizontally arranged to facilitate pedaling assistance to transfer the pedals from the ground to the frame for subsequent processing.

[0032] According to an embodiment of the present invention, the step assembly 10 has a connecting portion 200 and a step portion 300 connected to both ends of the connecting rod 100. During use, the connecting rod 100 is connected to the frame via the connecting portion 200, while the step portion 300 connected to the other end of the connecting rod 100 provides assistance when the user moves from the ground to the frame, making the transfer easier and improving work efficiency. Furthermore, the step assembly 10 with the above design is simple and reliable, saving production materials and reducing production costs while assisting user movement.

[0033] In some embodiments, the connecting portion 200 is provided with multiple connection points 210, which are spaced apart circumferentially along the edge of the connecting portion 200. It is understood that by providing connection points 210 on the connecting portion 200, fasteners can be connected and fixed through the connecting portion 200 when the connecting portion 200 is connected to the frame, making the assembly and connection process of the step assembly 10 simpler and ensuring a more reliable connection strength to meet the connection and usage requirements of the step. Similarly, to make the connection of the connection points 210 more reliable, multiple connection points 210 are provided and spaced apart axially along the edge.

[0034] In some embodiments, the connecting portion 200 is further provided with a fixing portion 220, and there are multiple fixing portions 220, which are arranged one-to-one with the connecting points 210. In this way, the fixing portions 220 are connected to the connecting portion 200. Since there are multiple fixing portions 220, the multiple fixing portions 220 are arranged one-to-one with the multiple connecting points 210, so that the fixing portions 220 can improve the structural reliability of the connecting portion 200 when connecting, and make the assembly and use of the ladder assembly 10 more reliable.

[0035] In some embodiments, the connecting rod 100 includes a first connecting rod 110 and a second connecting rod 120. The first connecting rod 110 is vertically arranged, and one end of the first connecting rod 110 is connected to the connecting portion 200. The second connecting rod 120 extends horizontally, and the first connecting rod 110 and the second connecting rod 120 are connected. One end of the second connecting rod 120 is connected to the step portion 300. It is understood that the connecting rod 100 is adapted to include the first connecting rod 110 and the second connecting rod 120, with the first connecting rod 110 extending vertically and the second connecting rod 120 extending horizontally, connecting the first connecting rod 110 and the second connecting rod 120 so that the structural configuration of the formed connecting rod 100 can meet the usage requirements for connecting the frame and supporting the step portion 300, so that the step assembly 10 can be constructed and used according to the design, simplifying the assembly process of the step assembly 10 and having high structural strength to meet the usage requirements.

[0036] In some embodiments, the first connecting rod 110 and the second connecting rod 120 are fixedly connected. This fixed connection of the first connecting rod 110 and the second connecting rod 120 provides the connecting rod 100 with higher structural strength to meet usage requirements, thus increasing the reliability of the ladder assembly 10.

[0037] In some embodiments, the first connecting rod 110 and the second connecting rod 120 are rotatably connected. This rotatable connection allows the second connecting rod 120 to be opened to expose the step portion 300 when the step assembly 10 is needed, facilitating subsequent use of the step assembly 10 and improving ease of use. Furthermore, after use, the second connecting rod 120 is retractable to roll up the support portion, providing protection for the step assembly 10 after use and improving its performance and lifespan.

[0038] In some embodiments, one end of the first connecting rod 110 is connected to the middle of the connecting portion 200, and one end of the second connecting rod 120 is connected to the middle of the tread portion 300. Thus, by adapting the first connecting rod 110 to the middle of the connecting portion 200 and the second connecting portion 200 to the middle of the tread portion 300, the connecting rod 100 can be connected in the middle, allowing the tread assembly 10 to form a centrally symmetrical structure. This results in better structural strength of the tread while simplifying the structural design and manufacturing process, improving production efficiency, and simplifying the structure. Furthermore, the tread assembly 10 achieves high structural performance while saving and reducing production materials, thereby lowering production costs.

[0039] In some embodiments, the step portion 300 is provided with anti-slip protrusions 310, and there are multiple anti-slip protrusions 310 spaced apart on the step portion 300. It is understood that providing multiple anti-slip protrusions 310 on the step portion 300 can give the step portion 300 a higher friction effect, providing greater assistance when stepping on the step portion 300, and improving the safety and reliability of the step assembly 10.

[0040] In some embodiments, a reinforcing flange 320 is provided on the outer periphery of the tread portion 300. That is, a reinforcing flange 320 is provided on the outer periphery of the tread portion 300. The reinforcing flange 320 is suitable for improving the structural strength of the outer periphery of the tread portion 300, thereby improving the overall structural strength of the tread portion 300, so as to improve the performance of the tread portion 300 to provide load-bearing assistance, and so that the use of the tread assembly 10 can meet the user's needs.

[0041] According to an embodiment of the present invention, a vehicle includes a step assembly 10 as described above. Thus, by providing the step assembly 10 as shown above on the vehicle, and by connecting a connecting portion 200 and a step portion 300 to both ends of a connecting rod 100, the connecting rod 100 is connected to the frame via the connecting portion 200 during use. The step portion 300 connected to the other end of the connecting rod 100 provides assistance when the user moves from the ground to the frame, making the transfer easier and improving work efficiency. Furthermore, the step assembly 10 with the above-described design is simple and reliable, saving production materials and reducing production costs while assisting user movement.
