Description

Technical Field

[0001] This utility model belongs to the field of vehicle step ladder technology, specifically relating to a multifunctional step bracket and step ladder for large vehicles. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Currently, large vehicles are widely used, and workers frequently use fixed ladders to access them for inspection, maintenance, and driving. Most existing ladders on large vehicles are fixed structures, increasing the vehicle's overall dimensions. When special operations are required, such as working in confined spaces or large-scale maintenance, the fixed ladders need to be removed because their protrusion beyond the vehicle frame is difficult and cumbersome. Furthermore, the relatively fixed length of the ladders prevents adaptation to different vehicle sizes; and since ladders are mostly located on the side of the vehicle, visibility is poor in dark environments, increasing the risk of missteps when entering or exiting the vehicle. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a multifunctional step bracket and ladder for large vehicles, which solves the issues that existing large vehicle ladders cannot be disassembled and are not applicable to various vehicle models.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] In a first aspect, this utility model provides a multifunctional step bracket for large vehicles, comprising: a bracket body, a step panel at the top of the bracket body, an elongated hole on the step panel near the bracket body, an insert plate at the bottom of the bracket body and disposed on the side of the bracket body away from the elongated hole, the elongated hole cooperating with the insert plate on the adjacent bracket body; and a plurality of slots at one end of the bracket body for connecting fixing pins on the vehicle frame.

[0007] As a further implementation, the card slot is a hanging hole structure; the hanging hole structure includes a first circular hole and a second circular hole, the diameter of the first circular hole is smaller than the diameter of the second circular hole, and the first circular hole and the second circular hole are connected.

[0008] As a further implementation, the bracket body is provided with a connecting hole at one end where the hanging hole is located, and the connecting hole is used to fix the bracket body to the vehicle frame by fasteners.

[0009] As a further implementation, the support body is a polygonal frame structure.

[0010] As a further implementation, the shape of the foot panel is the same as the polygon formed by the support body, and the edge of the foot panel is fixedly connected to the top of the support body.

[0011] As a further implementation, the support body is formed by bending strip steel plates and fixing the two ends of the strip steel plates together, and is connected to the foot panel by welding.

[0012] Alternatively, the bracket body and the foot panel can be integrally formed by high-pressure casting.

[0013] As a further implementation, the step panel is a flat steel plate with a lentil pattern on the surface; or the step panel is a steel grating.

[0014] As a further implementation, the other end of the bracket body is provided with multiple through holes, on which lamps are installed, and on which plugs are provided for connecting to the vehicle's power supply.

[0015] As a further implementation, the foot panel and the bracket body are coated with anti-rust paint.

[0016] Secondly, this utility model provides a multi-functional step ladder for large vehicles, which is assembled from multiple multi-functional step brackets for large vehicles as described above.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are:

[0018] The sliding fit design of the insert plate and elongated hole in this invention enables tool-free assembly. Adjacent brackets can be connected laterally by simple plug-in, significantly reducing assembly complexity. The cooperation between the slot and the frame fixing pin makes it easy to install the step bracket on the frame, avoiding the problem of the step bracket being too wide when traveling on narrow roads, and it is simpler and more practical than the existing folding bracket structure.

[0019] This invention simplifies the installation of the step bracket by using hanging holes, preventing situations where the excessive width of the step bracket makes passage impossible in narrow passages. Simultaneously, a connecting hole is provided at the end of the bracket body where the hanging holes are located, allowing the bracket body to be fixed to the vehicle frame using fasteners. When the vehicle travels on bumpy roads for extended periods, the fasteners easily secure the bracket body to the frame, preventing the step bracket from detaching during bumpy rides.

[0020] The support body of this utility model is formed by bending strip steel plates and fixing the two ends of the strip steel plates together. It is then connected to the foot panel by welding. The bending process of the strip steel plates can quickly realize complex shapes to adapt to different design requirements. The welding connection at both ends can ensure the firmness of the support and the foot panel, which is suitable for load-bearing scenarios. Alternatively, the support body and the foot panel can be integrally formed by high pressure casting without connection seams, avoiding stress concentration, and having better fatigue resistance, which is suitable for high-frequency load scenarios. Lightweight materials such as aluminum alloy can be used. Attached Figure Description

[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise expressly indicated by the present invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Example 1

[0029] This embodiment provides a multi-functional step bracket for large vehicles, such as... Figures 1-2As shown, the device includes: a support body 1, a foot panel 2 at the top of the support body 1, an elongated hole 7 on the foot panel 2 near the support body 1, and an insert plate 6 at the bottom of the support body 1, located away from the elongated hole 7. The elongated hole 7 engages with the insert plate 6 on the adjacent support body 1. One end of the support body 1 has multiple slots for connecting to the fixing pins on the frame 8. Specifically, the sliding fit design of the insert plate 6 and the elongated hole 7 enables tool-less assembly. Adjacent supports can be connected in the length direction simply by plugging them in, significantly reducing assembly complexity. The engagement of the slots with the fixing pins on the frame 8 makes it easy to install the step support on the frame 8, avoiding the problem of the step support being too wide when traveling on narrow roads, and is simpler and more practical than existing folding support structures.

[0030] The slot is a hanging hole 3 structure; the hanging hole 3 structure includes a first round hole and a second round hole, the diameter of the first round hole is smaller than the diameter of the second round hole, and the first round hole and the second round hole are connected; specifically, the bracket body 1 is fixedly connected to the fixing pin by inserting the fixing pin into the second round hole and sliding it into the first round hole; the hanging hole 3 simplifies the installation difficulty of the step bracket and avoids the situation where the step bracket is too wide to pass through in narrow passages.

[0031] The bracket body 1 is provided with a connecting hole 4 at one end of the hanging hole 3. The connecting hole 4 is used to fix the bracket body 1 to the frame 8 with fasteners. When large vehicles travel on bumpy roads for a long time, the bracket body 1 is simply fixed to the frame 8 with fasteners to prevent the step bracket from falling off during bumpy driving.

[0032] The bracket body 1 is a polygonal frame structure. In this embodiment, the bracket body 1 has a rectangular structure, which makes the bottom of the step bracket form a cavity structure for storing the connecting wires of the lamps, etc. At the same time, while ensuring the load-bearing capacity, the weight of the step bracket itself is reduced.

[0033] The shape of the step panel 2 is the same as the polygon formed by the bracket body 1, and the edge of the step panel 2 is fixedly connected to the top of the bracket body 1, so that the bracket body 1 and the step panel 2 form a hollow shell, which reduces its own weight while ensuring the load-bearing capacity of the step bracket, and also reduces the difficulty of disassembling and assembling the step bracket to a certain extent.

[0034] The support body 1 is formed by bending strip steel plates and fixing the two ends of the strip steel plates together. It is then connected to the foot panel 2 by welding. The bending process of the strip steel plates can quickly realize complex shapes to adapt to different design requirements. The welding connection at both ends can ensure the firmness of the support and the foot panel 2, which is suitable for load-bearing scenarios. Alternatively, the support body 1 and the foot panel 2 can be integrally formed by high pressure casting without connection seams, avoiding stress concentration and providing better fatigue resistance. This is suitable for high-frequency load scenarios and can be made of lightweight materials such as aluminum alloy.

[0035] The step panel 2 is a flat steel plate with a lentil pattern on its surface. The lentil-shaped raised pattern on the surface can significantly increase friction and effectively reduce the risk of slipping in humid or oily environments. The raised structure of the lentil pattern enhances the deformation resistance of the steel plate to a certain extent. Under the same thickness, its load-bearing stability under local stress is better than that of ordinary steel plates. In this embodiment, the step panel 2 is a flat steel plate with a lentil pattern on its surface.

[0036] Since the steel grating is welded from flat steel and twisted square steel, if the step panel 2 is a steel grating, it also has a strong load-bearing capacity and can withstand concentrated loads or uniform loads. The surface is made of serrated flat steel or anti-slip treatment, which can provide high friction even in wet or oily environments, reducing the risk of people slipping.

[0037] The other end of the bracket body 1 is provided with multiple through holes 5. In this embodiment, there are five through holes arranged in a trapezoidal shape. A lamp is installed on the through hole 5, and a plug is provided on the lamp for connecting to the vehicle's power supply. The lamp is a work lamp and a warning lamp, which provides light source in dark conditions, making it easier for the driver to get on and off the vehicle in the dark and avoid stepping into the air. It is also used to remind other working vehicles to pay attention to the outline of this vehicle and avoid it.

[0038] The step panel 2 and the bracket body 1 are coated with anti-rust paint, which can effectively prevent the step bracket from rusting.

[0039] Example 2

[0040] This embodiment provides a multi-functional staircase for large vehicles, such as... Figure 3 As shown, the multi-functional step bracket for large vehicles is assembled from multiple brackets. The number of step brackets can be adjusted to meet the staircase installation requirements of different vehicles. In this embodiment, four step brackets are provided.

[0041] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
