Description

Technical Field

[0001] This application relates to the field of driver's cab technology, and more specifically, to a step structure for a driver's cab and a vehicle. Background Technology

[0002] The driver's cab is usually a certain height off the ground. Steps can divide this height into several smaller drops, making it easier and more convenient for the driver and passengers to get on and off the vehicle.

[0003] However, existing cab steps are mostly designed to be straight up and down, which has many drawbacks. It is very inconvenient for drivers to enter and exit the cab space, and they are prone to misstepping. Especially in bad weather or complex road conditions, drivers need to enter and exit the cab space quickly and safely, and traditional cab steps cannot meet these needs. Utility Model Content

[0004] This application provides a step structure for the driver's cab and a vehicle that facilitates the driver's entry and exit from the driving space.

[0005] In a first aspect, this application provides a step structure for a driver's cab, comprising:

[0006] A cab assembly having a doorway and a driving space, the doorway communicating with the driving space;

[0007] A step assembly is located below the doorway and is fixedly installed on the cab assembly; the step assembly includes multiple steps, which are spaced apart in the vertical direction.

[0008] In this configuration, among two adjacent pedals, the lower pedal is offset outward in the horizontal direction relative to the upper pedal.

[0009] Optionally, in two adjacent pedals, the lower pedal is offset outward in the horizontal direction relative to the upper pedal by a dimension greater than or equal to 80 mm; or,

[0010] In two adjacent pedals, the pedal located below is offset outward in the horizontal direction relative to the pedal located above by an amount ranging from 60 mm to 200 mm.

[0012] The number of pedals is 3, and in two adjacent pedals, the pedal located below is offset outward in the horizontal direction by a dimension ranging from 60mm to 120mm.

[0013] Optionally, the door trim panel includes a connected bent portion and a mounting portion, the bent portion being located above the mounting portion, and the mounting portion being used to mount at least two of the pedals;

[0014] The bent portion is recessed inward, and the mounting portion extends outward from the bent portion in the vertical direction, so that the lower pedal of the two adjacent pedals mounted on the door panel is offset outward in the horizontal direction relative to the upper pedal.

[0015] Optionally, the cab assembly further includes a bracket structure that securely connects the pedal and trim structure and is used to secure it to the frame assembly.

[0016] Optionally, the minimum vertical spacing between adjacent pedals is in the range of 350mm to 400mm; and / or,

[0017] The multiple pedals include a bottom pedal located at the lowest point, the bottom pedal being at a height of 450mm to 550mm above the ground.

[0018] Optionally, the width of the pedal is in the range of 180mm to 220mm; and / or,

[0019] The length of the pedal is in the range of 300mm to 550mm.

[0023] The step structure for the driver's cab and the vehicle provided in this application have at least the following advantages:

[0024] In this design, the lower pedal is offset outward in the horizontal direction relative to the upper pedal, which provides horizontal cushioning. This changes the traditional straight-up and down steps without horizontal cushioning, making the driver's foot movement more natural when going up and down steps, reducing the risk of misstepping, and making it more convenient to enter and exit the driving space, thus meeting the driver's need for quick entry and exit from the driving space.

[0030] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0031] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0032] This application provides a step structure for a driver's cab and a vehicle thereof. The step structure for a driver's cab and the vehicle thereof are described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0033] refer to Figures 1 to 3 This application provides a step structure for a driver's cab, including a driver's cab assembly and a step assembly 10. The driver's cab assembly has a doorway 23 and a driving space, with the doorway 23 communicating with the driving space, allowing the driver to enter and exit the driving space through the doorway 23. An outer door 30 is provided at the doorway 23 to open and close the doorway 23.

[0034] The step assembly 10 is located below the doorway 23 and is installed on the cab assembly. For example, the step assembly 10 can be installed on the outer shell and interior structure of the cab assembly, but is not limited thereto. The step assembly 10 includes a plurality of steps 11, which are spaced apart vertically, the vertical direction of which is consistent with the height direction of the cab. Figure 3 The up and down directions are shown. The driver can gradually move up and down using multiple pedals 11 spaced apart.

[0035] In particular, among two adjacent pedals 11, the lower pedal 11 is outward in the horizontal direction relative to the upper pedal 11 (see reference). Figure 3 The pedal 11 is offset outwards (as shown). Here, "outwards" refers to the direction away from the driving space, that is, the side closer to the external environment. In other words, the lower pedal 11 is closer to the external environment in the horizontal direction than the upper pedal 11.

[0036] It is easy to understand that during normal walking or climbing, people's feet move not only vertically but also horizontally when they lift and lower. Therefore, in this design, the lower pedal 11 is offset outward in the horizontal direction relative to the upper pedal 11. This provides horizontal cushioning, changing the traditional straight-up-down stairs without horizontal cushioning, making the driver's foot movement more natural when going up and down stairs, reducing the risk of misstepping, and making it easier to enter and exit the driving space, thus meeting the driver's need for quick entry and exit. Furthermore, through the above-mentioned offset setting, the step assembly of this design eliminates the need for complex transmission structures, making it easy to implement in manufacturing.

[0037] In one embodiment, among two adjacent pedals 11, the lower pedal 11 is offset outward in the horizontal direction relative to the upper pedal 11 by a dimension greater than or equal to 80 mm. This offset dimension is defined as "the minimum distance between the outer edges of the lower pedal 11 and the outer edges of the upper pedal 11," and can be referenced. Figure 3 L1 is shown.

[0038] Sufficient offset dimensions provide drivers with more space to land. In situations such as poor lighting, severe weather (e.g., heavy rain or snow obstructing visibility), or complex road conditions (vehicle bumps or tilts), drivers may not be able to accurately control their foot placement. Therefore, the offset of 80mm or more in this solution can effectively reduce the possibility of misjudging and missing a step, greatly improving safety during getting on and off the vehicle.

[0039] For example, in two adjacent pedals 11, the outward offset of the lower pedal 11 relative to the upper pedal 11 in the horizontal direction can be 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, or 160mm, but is not limited thereto.

[0040] In another embodiment, in two adjacent pedals 11, the lower pedal 11 is offset outward in the horizontal direction relative to the upper pedal 11 by an amount ranging from 60mm to 200mm. A 60mm offset provides sufficient horizontal buffer space for the driver's feet. This distance effectively reduces the risk of misstepping when the driver steps from the upper pedal 11 to the lower pedal 11. Space around the driver's cab is typically limited, and the design of the steps needs to consider their compatibility with the surrounding environment. Excessive offset would occupy too much lateral space, potentially affecting the overall vehicle layout, such as interfering with surrounding equipment or other components, or causing the steps to exceed the reasonable support range of the vehicle chassis, affecting the stability of the step structure. A 200mm upper limit ensures that the steps do not negatively impact the overall space and structure of the vehicle while meeting usage requirements.

[0041] For example, in two adjacent pedals 11, the outward offset of the lower pedal 11 relative to the upper pedal 11 in the horizontal direction can be 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, or 200mm, but is not limited thereto.

[0042] In one embodiment, in the vertical orthographic projection of two adjacent pedals 11, the projection area of ​​the lower pedal 11 partially overlaps with the projection area of ​​the upper pedal 11. This partially overlapping projection design allows the pedals 11 to be distributed more efficiently within a limited space. In situations where space around the cab is limited, this design prevents the pedals 11 from extending excessively in the horizontal direction, thereby effectively reducing the lateral space occupied by the step assembly 10 as a whole.

[0043] In one embodiment, the minimum vertical spacing between adjacent pedals 11 is between 350mm and 400mm. Here, minimum spacing refers to the minimum distance between the tread surfaces of one of two adjacent pedals 11 and the tread surfaces of the other, as can be referenced. Figure 3 As shown in L2, the step surface is the surface of the pedal for the user to step on.

[0044] For example, the minimum spacing can be, but is not limited to, 350mm, 360mm, 370mm, 380mm, 390mm, or 400mm. This spacing range matches the average stride length of most people. The normal walking stride length for an average adult is approximately 500-800mm. When going up or down stairs, the stride length is appropriately reduced to maintain balance and stability. A spacing of 350mm-400mm allows the driver to move between adjacent steps with a more natural and comfortable gait, avoiding frequent and cramped steps due to excessively small spacing, and also preventing large leaps due to excessively large spacing, thus reducing physical fatigue and the risk of falls.

[0045] In one embodiment, the plurality of pedals 11 includes a bottom pedal 11 located at the lowest point, wherein the minimum distance between the bottom pedal 11 and the ground is in the range of 450mm to 550mm, where the ground is the support surface supporting the vehicle, and the minimum distance can be 450mm, 460mm, 470mm, 480mm, 490mm, 500mm, 510mm, 520mm, 530mm, 540mm, or 550mm.

[0046] This spacing effectively prevents mud, water, and sewage from splashing directly onto the pedal 11 when the vehicle is in motion due to the rotation of the wheels. If the spacing is too small, water and mud on the ground can easily be splashed onto the pedal 11 by the wheels, making the surface of the pedal 11 slippery and increasing the risk of the driver slipping when getting in and out of the vehicle. A suitable spacing ensures that the pedal 11 remains relatively dry and clean, maintaining good pedaling conditions. Furthermore, this spacing range is adapted to the length of the human leg and movement habits. For most drivers, within this height range, stepping onto or off the bottom pedal 11 from the ground involves a relatively natural leg flexion and extension motion. It avoids the difficulty of crossing due to an excessively large spacing, or the need for excessive bending or knee flexion due to an excessively small spacing, reducing fatigue during getting in and out of the vehicle and improving convenience.

[0047] In some embodiments, the number of pedals 11 can be 2, 3, 4, 5, 6, etc. The number of pedals 11 is related to the height of the cab floor 60 and the spacing between the pedals 11. This application does not specifically limit this. However, for the convenience of those skilled in the art, this application provides the following specific solutions when the number of pedals 11 is 2 and 3.

[0048] In one embodiment, the height of the cab floor 60 relative to the ground can be between 1600mm and 1800mm, and the number of pedals 11 is three. In two adjacent pedals 11, the lower pedal 11 is horizontally offset outward by a distance between 60mm and 120mm. For example, the height of the cab floor 60 relative to the ground can be 1600mm, 1700mm, or 1800mm, and the offset distance can be 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, or 120mm, but is not limited to these.

[0049] For some heavy trucks or large buses, the height and spatial layout of the cab determine that three steps 11 are more suitable. In this case, limiting the misalignment of adjacent steps 11 to the range of the above embodiment can make the steps more coordinated and unified with the overall appearance and internal structure of the vehicle, and avoid affecting the overall aesthetics and practicality of the vehicle due to unreasonable step design.

[0050] In another embodiment, the height of the cab floor 60 relative to the ground can be between 1100mm and 1300mm, and the number of pedals 11 is two. In two adjacent pedals 11, the lower pedal 11 is horizontally offset outward by a distance between 60mm and 150mm. For example, the height of the cab floor 60 relative to the ground can be 1100mm, 1200mm, or 1300mm, and the offset distance can be 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, or 150mm.

[0051] Setting the number of pedals 11 to 2 is suitable for some vehicles with relatively low cab height and limited space, while the offset size range of 60mm to 150mm is to meet the needs of different vehicles and users as much as possible while ensuring safety and comfort.

[0052] In one embodiment, the cab assembly further includes a trim panel structure, to which the step assembly 10 is mounted. Integrating the step assembly 10 into the trim panel structure simplifies the process compared to directly mounting the step onto other complex cab structures. Mounting methods include, but are not limited to, bolting, riveting, and snap-fitting.

[0053] Furthermore, the trim structure includes a door trim panel 20 and a front bumper trim panel 40 (i.e., a front bumper trim panel). The door trim panel 20 is located above the front bumper trim panel 40. A portion of the multiple step pedals 11 are mounted on the door trim panel 20, and another portion is mounted on the front bumper trim panel 40. The door trim panel 20 and the front bumper trim panel 40 are located in different positions and each has unique spatial conditions. Distributing the step assembly 10 across these two trim panels makes full use of the space around the door and front bumper, cleverly avoiding the layout areas of other vehicle components, and making the placement of the step pedals 11 more compact and rational.

[0054] In one specific embodiment, the door trim panel 20 includes a connected bend 21 and a mounting portion 22. The bend 21 is located above the mounting portion 22, and the mounting portion 22 is used to mount at least two pedals 11. The bend 21 is recessed inward, and the mounting portion 22 gradually extends outward from the bend 21 in the vertical direction, so that of two adjacent pedals 11 mounted on the door trim panel 20, the lower pedal 11 is offset outward in the horizontal direction relative to the upper pedal 11.

[0055] By incorporating the bend 21, the door trim panel 20 is first recessed inwards, and then the mounting portion 22 gradually extends outwards vertically from the bend 21. This design cleverly achieves the outward offset of adjacent pedals 11 in the horizontal direction. The inclined extension of the mounting portion 22 allows adjacent pedals 11 mounted thereon to naturally form a layout where the lower pedal 11 is offset outwards relative to the upper pedal 11, eliminating the need for additional complex structural designs to achieve this pedal offset and simplifying the manufacturing process.

[0056] like Figure 3 In the illustrated embodiment, there are three pedals 11, including a top pedal 11, a middle pedal 11, and a bottom pedal 11. The top pedal 11 and the middle pedal 11 are mounted on the door trim panel 20, and the bottom pedal 11 is mounted on the rear trim panel. The rear trim panel is located outside the door trim panel 20, which naturally places the bottom pedal 11 outside the middle pedal 11, causing the bottom pedal 11 to be naturally offset outward.

[0057] In one embodiment, the cab assembly further includes a bracket structure that securely connects the pedal 11 and the trim structure, and is used to fix them to the vehicle's frame assembly. Connection methods include, but are not limited to, screwing, welding, riveting, and snap-fitting. The bracket can indirectly fix the trim structure and the step to the frame assembly, improving the installation stability of the pedal 11 and the trim structure.

[0058] Please refer to Figure 4 Specifically, the support structure 50 includes a first support 51 and a second support 52.

[0059] The first bracket 51 is fixedly connected to the door trim panel 20, and is also fixedly connected to the door trim panel 20 and the pedal 11 mounted on the door trim panel 20 by bolts. Specifically, the bolts can pass through the first bracket 51, the door trim panel 20, and the pedal 11 to simultaneously connect them. The first bracket 51 includes a first connecting portion 511 and a second connecting portion 512. The first connecting portion 511 is fixed to the door trim panel 20 by bolts, and the second connecting portion 512 is fixed to both the door trim panel 20 and the pedal 11 by the same bolts.

[0060] The second bracket 52 is fixedly connected to the front bumper trim 40, and is also fixedly connected to the front bumper trim 40 and the pedal 11 by bolts. That is, the same bolts can pass through the second bracket 52, the front bumper trim 40, and the pedal 11 to connect the second bracket 52, the front bumper trim 40, and the pedal 11 simultaneously. Specifically, the second bracket 52 includes a third connecting part 521 and a fourth connecting part 522. The second connecting part 521 is fixed to the front bumper trim 40 by bolts, and the fourth connecting part 522 is fixed to the front bumper trim 40 and the pedal 11 by bolts.

[0061] In one embodiment, the width of the pedal 11 is in the range of 180mm to 220mm, and the length of the pedal 11 is in the range of 300mm to 550mm. Here, the width and length are consistent with the width and length of the cab. For example, the width of the pedal 11 can be 180mm, 190mm, 200mm, 210mm, or 220mm, and the length of the pedal 11 can be 300mm, 310mm, 320mm, 330mm, 340mm, 350mm, 360mm, 370mm, 380mm, 390mm, 400mm, 410mm, 420mm, 430mm, 440mm, 450mm, 460mm, 470mm, 480mm, 490mm, 500mm, 510mm, 520mm, 530mm, 540mm, or 550mm, but is not limited to these values.

[0062] In one embodiment, the step surface of the pedal 11 is provided with an anti-slip structure. The step surface is the surface of the pedal 11 used by the driver to step on. The anti-slip structure can increase the friction between the driver's shoe sole and the pedal 11. In rainy weather, there may be water accumulation on the surface of the pedal 11, or after washing the car, the pedal 11 may not be completely dry, or in some special working scenarios, the pedal 11 may be contaminated with oil, etc., all of which can make the surface of the pedal 11 slippery. The anti-slip structure can effectively reduce the risk of slipping and ensure that the driver can step steadily on the pedal 11 when entering and exiting the cab, even if he is in a hurry.

[0063] Anti-slip structures can be textured, granular, coated, or raised, but are not limited to these. Textured anti-slip structures can include horizontal and vertical stripes; granular anti-slip structures can include dotted and blocky particles; coated anti-slip structures can include anti-slip paint, rubber coatings, and polymer anti-slip coatings; raised anti-slip structures can include striped raised areas and circular raised areas.

[0064] This application also provides a vehicle including the step structure for the driver's cab described in any of the above embodiments or implementations.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
