DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figures 1 to 11 The embodiment of the present application provides a climbing device and a vehicle cab thereof, which can solve the problem in the related art that there is no climbing device on the cargo commercial vehicle that is convenient for checking and adjusting the rear cargo box and the accessories on the top of the cab, making it inconvenient for users to climb and operate.

[0033] Existing commercial vehicles are usually only designed with a step for getting on the vehicle, which is located at the front lower part of the cab to facilitate the driver and passengers to enter the cab space. For tractor models, a step-able workbench is also designed on the rear chassis frame to facilitate maintenance personnel to adjust the components at the rear of the vehicle;

[0034] For commercial cargo vehicles, in some usage scenarios, the driver needs to check and adjust the rear cargo box and accessories on the top of the cab. However, the current industry-designed vehicles do not have a stepping structure, making it inconvenient for users to climb and operate.

[0035] In view of the problem that there is no climbing device on a cargo commercial vehicle to facilitate the inspection and adjustment of the rear cargo box and the accessories on the top of the cab, which is inconvenient for users to climb. In the first aspect, the embodiment of the present application provides a climbing device, which includes: a pedal assembly 1 and an armrest assembly 2, the pedal assembly 1 is arranged on the side wall 4 of the cab, the pedal assembly 1 is used to be arranged between the door frame and the chassis frame 5, and the pedal assembly 1 is located on the top of the wheel cover 3; the armrest assembly 2 is arranged on the outer surface of the cab, and there is a set distance between the armrest assembly 2 and the pedal assembly 1.

[0036] In the present application, a pedal assembly 1 and a graspable armrest assembly 2 are designed on the side and rear of the cab. When the driver and passengers need to repair or adjust the cargo box or top accessories at the rear of the cab, they can go up to the chassis workbench 6 via the steps on the chassis frame 5, and then step from the chassis workbench 6 to the pedal assembly 1. The armrest assembly 2 can provide a gripping place to ensure safety. After the driver and passengers step on the pedal assembly 1 on the side and rear of the cab via the chassis workbench 6, they can grab the armrest assembly 2 to repair and adjust the rear cargo box or top accessories.

[0037] When using the pedal assembly 1 on the wheel cover 3, the user can climb onto the chassis workbench 6 through the chassis step, and then step onto the pedal assembly 1, or step onto the pedal assembly 1 from the door step. Among them, the pedal assembly 1 has a set height relative to the chassis workbench 6. In this embodiment, the set height is set to 447mm, that is, the height of the pedal assembly 1 relative to the chassis workbench 6 is 447mm; it should be noted that in other embodiments, the set height can also be adjusted according to actual needs. Furthermore, in this embodiment, the set distance is set to 1310mm, that is, the vertical distance between the pedal surface of the pedal assembly 1 and the armrest assembly 2 is 1310mm. This distance can meet the needs of people standing on the pedal assembly 1, and their hands can be conveniently grasped at the armrest assembly 2 to prevent unstable standing and falling, thereby ensuring safety.

[0038] The pedal assembly 1 is arranged above the wheel cover 3. Since the wheel cover 3 is a plastic part with low strength and cannot support the weight of a person stepping on it, the pedal assembly 1 needs to be connected to the sheet metal of the cab side panel 4 through a bracket.

[0039] Based on the above embodiments, in this embodiment, the pedal assembly 1 includes: a support bracket 10 and a foot pedal 11, the support bracket 10 is used to be fixed on the side panel 4 of the cab; one end of the foot pedal 11 is connected to the support bracket 10, and the other end is used to be connected to the side panel 4 of the cab.

[0040] In this embodiment, the support bracket 10 is fixed to the sheet metal of the cab side panel 4, and the support bracket 10 supports and fixes the foot pedal 11, thereby playing a role in structural reinforcement.

[0041] Since the pedal assembly 1 is an optional installation based on the existing body-in-white and wheel cover 3, it is necessary to ensure that the original wheel cover 3 is only partially cut to realize the installation of the pedal assembly 1, and to ensure that the pedal assembly 1 can bear the weight of the human body, so the structural design is difficult. In this embodiment, at least two groups of support brackets 10 are provided. These two groups of support brackets 10 need to be accurately calculated and laid out, and are firmly installed at the optimal force-bearing positions on both sides of the pedal 11 along the length direction of the vehicle body. Such a design is not only to effectively disperse the huge impact force and weight load generated when people step on the pedal 11, and prevent structural damage caused by single-point force concentration, but also to greatly reduce the distortion or plastic deformation that may be caused by the stepping action on the body-in-white structure and the pedal 11 itself, thereby ensuring the stability, rigidity and durability of the entire vehicle body structure under long-term use. It should be noted that in this application, the number of support brackets 10 is determined according to needs, and in this embodiment, there is no restriction on it.

[0042] The support bracket 10 is configured to be installed and fixed to the side wall of the body in white. Furthermore, the support bracket 10 includes: a support beam 100 and a support seat 101, the support beam 100 is used to be fixed on the side wall 4 of the cab; one end of the support seat 101 is fixed to the support beam 100, and the other end is fixed to the foot pedal 11.

[0043] Specifically, the support bracket 10 includes a support beam 100 fixedly connected to the sheet metal of the vehicle body, that is, the cab side panel 4, and a support seat 101 fixedly connected to the foot pedal 11. The support beam 100 and the support seat 101 are both metal parts. Furthermore, flange structures are provided on both sides of the support beam 100 to ensure the structural rigidity when stepped on; wherein, the existence of the flange structures on both sides of the support beam 100 is mainly to significantly enhance the overall strength and stability of the support beam 100; the flange structures effectively disperse the pressure and load from all parties by expanding the force-bearing area of ​​the edge of the support beam 100, thereby greatly improving the durability and safety of the structure when facing external force impact or long-term bearing; specifically, the design of the flange structure not only takes into account the principles of mechanics, but also takes safety as the primary consideration. It is like putting a layer of "protective armor" on the support beam 100, so that under extreme conditions, such as strong vibration, heavy load compression, etc., the support beam 100 can still maintain the integrity and stability of the structure, and effectively prevent the risk of fracture or collapse caused by local stress concentration; such a design not only extends the service life of the support beam 100, but also ensures the safety of personnel at critical moments.

[0044] The support beam 100 and the support seat 101 are firmly connected and fixed by welding. When the two groups of support brackets 10 are arranged, the support brackets 10 are designed to be small in size, which can ensure sufficient support rigidity under the premise of less material. Its optimized structural design not only reduces the amount of material used and reduces costs, but also ensures that the support brackets 10 can remain stable and not easily deformed when bearing loads through precise mechanical calculations, thereby effectively improving the reliability and safety of the overall structure. In order to ensure the safe and reliable service life of the support bracket 10, other factors can also be considered: in terms of material selection, high-quality and high-strength materials are selected. These materials have good fatigue resistance and corrosion resistance and can operate stably for a long time in harsh environments; in terms of production technology, advanced processing technology and precision testing equipment are used to ensure that the manufacturing accuracy and quality of each support bracket 10 meet the standards, avoiding safety hazards caused by manufacturing defects. In addition, the support bracket 10 can also be regularly maintained and inspected to promptly discover and deal with potential problems to ensure that the support bracket 10 can maintain a good working condition throughout its service life.

[0045] Furthermore, the design of the support beam 100 is integrated into the existing profile structure of the cab side panel 4, and two openings are added at two key positions, the upper and lower, to provide the necessary interface for installing the support beam 100. In order to ensure that the pedal assembly 1 can more effectively disperse the stress generated when the foot pedal 11 is stepped on after installation, it is necessary to arrange the positions of the two groups of mounting holes: the two groups of mounting holes are arranged at the front and rear ends of the pedal assembly 1 respectively. Such a layout can not only maximize the balance of force and reduce the risk of local stress concentration, but also improve the stability and comfort when stepping on. At the same time, in order to further enhance the stress dispersion effect, the two openings on the support beam 100 are also separated as much as possible in the upper and lower directions, forming a unique "distributed" support structure. This design not only helps to improve the overall strength of the support beam 100, but also can more effectively absorb and disperse stress during the stepping process, thereby extending the service life of the support beam 100. However, while pursuing the stress dispersion effect, it is also necessary to fully consider the impact of the opening distance on the shape and weight of the part: although an excessively large opening distance can further enhance the stress dispersion effect, it may also cause the shape of the part to become complex, increase the difficulty of processing and manufacturing costs, and thus cause the problem of increased weight. Therefore, in the design process, CAE (computer-aided engineering) analysis technology can be combined to simulate the impact of different opening positions on structural strength and weight, and perform multiple iterations and optimizations. Finally, based on the analysis structure, a reasonable and economical opening position is confirmed to ensure that the support beam 100 can meet the strength requirements while maintaining a lightweight design, providing a strong guarantee for the overall performance of the cab and the comfort experience of the passengers.

[0046] The shape of the support bracket 10 is designed to be a U-shaped cross section. This design not only enhances the cross-sectional inertia moment of the parts, thereby greatly improving the strength and rigidity of the overall structure, but also ensures the stability and durability of the support bracket 10 under various complex working conditions. The curvature and wall thickness distribution of the U-shaped cross section can also be optimized to further improve its torsion and bending resistance, so that the support bracket 10 can still maintain excellent mechanical properties when subjected to heavy loads or dynamic loads.

[0047] In view of the specific requirements of the installation boundary, the support beam 100 is designed to be a U-shaped structure facing inward and backward. This design not only perfectly meets the installation process requirements of the pedal assembly 1, ensuring the accuracy and firmness of the installation, but also provides sufficient support area for the pedal assembly 1 through reasonable spatial layout, effectively disperses the impact force during pedaling, and further improves the overall strength performance. By adopting high-strength, lightweight materials and precise manufacturing processes, it is ensured that the support beam 100 achieves a lightweight design while maintaining high strength. In order to further reduce weight, a plurality of weight-reducing holes are opened on the support seat 101. The layout, shape and size of these holes need to undergo rigorous calculation and simulation analysis to ensure that the overall stability and strength of the structure are not affected while reducing weight. Ultimately, the support structure achieves a weight reduction of up to 30% compared to the traditional structure. Reduced manufacturing costs.

[0048] Furthermore, the pedal assembly 1 also includes a reinforcing plate 12 , and the reinforcing plate 12 is fixed between the supporting bracket 10 and the foot pedal 11 .

[0049] Specifically, the reinforcing plate 12, as a key structural reinforcement component, is tightly fixedly connected to the support bracket 10 and the foot pedal 11 by high-strength bolts to form a stable overall structure. The reinforcing plate 12 is made of metal material and has excellent strength and durability. Its main function is to disperse the stress generated when stepping on the foot pedal 11 and prevent structural damage caused by local overload.

[0050] In addition to various holes and precise positioning holes reserved for installation on the reinforcing plate 12 to facilitate precise assembly with other components, pits and reinforcing ribs are also specially set. The pit design not only helps to reduce weight, but also increases the flexibility of the structure to a certain extent. When the reinforcing plate 12 is subjected to external force, the pit can effectively offset the elastic deformation of the plate, so that the surface of the plate can remain flat, thereby improving the stability and overall rigidity of the reinforcing plate 12. In addition, the pit can disperse and strengthen the stress on the plate 12 to prevent structural damage caused by local stress concentration. This design can extend the service life of the reinforcing plate 12 and improve its durability; and the reinforcing ribs significantly improve the rigidity and deformation resistance of the reinforcing plate 12 through reasonable layout and shape. The reinforcing ribs can effectively prevent the reinforcing plate 12 from twisting and deforming due to uneven stress caused by differences in wall thickness, ensuring the stability and reliability of the entire structure.

[0051] On the basis of the above-mentioned embodiment, in this embodiment, the pedal assembly 1 is provided with an anti-slip protrusion 110 structure and a drainage groove 111 .

[0052] Specifically, in this embodiment, the footrest 11 is set as an injection molded part, which not only has a decorative effect, but more importantly, ensures anti-slip performance when stepped on. In this embodiment, the stepping part of the footrest 11 is designed, and the length and width are determined to be 420mm long and 105mm wide. This size setting fully considers ergonomic factors, aims to meet the space requirements of human feet when stepping on, and ensures comfort and stability of stepping. It should be noted that in other embodiments, the length and width can also be adjusted as needed.

[0053] In order to further enhance the anti-skid effect, an anti-skid protrusion 110 structure is specially designed on the foot pedal 11. These anti-skid protrusions 110 adopt a scientific and reasonable layout and shape, which can significantly increase the friction between the sole of the foot and the foot pedal 11, effectively prevent slipping during the pedaling process, and thus ensure the safety of the user. In addition, considering that the foot pedal 11 may be contaminated with dirt such as mud and water during use, drainage grooves 111 for drainage and mud are also designed on the foot pedal 11 for easy cleaning and maintenance. These drainage grooves 111 can not only quickly drain the mud and water on the foot pedal 11, but also effectively prevent the risk of slipping caused by accumulated water, further improving safety. At the same time, the design of the drainage grooves 111 also takes into account aesthetics, ensuring that while maintaining practical functions, the overall appearance of the foot pedal 11 is not affected.

[0054] The pedal assembly 1 composed of the above structure can meet the pedal strength requirements of personnel, and the components of the device will not be damaged.

[0055] On the basis of the above embodiments, in this embodiment, the armrest assembly 2 includes: an upper armrest 21 and a side armrest 20, the upper armrest 21 is used to connect to the outer surface of the cab and is located at the top of the pedal assembly 1, and there is a set height between the upper armrest 21 and the pedal assembly 1; the side armrest 20 is used to connect to the outer surface of the cab and is located on one side of the pedal assembly 1, and the side armrest 20 is also located between the upper armrest 21 and the pedal assembly 1.

[0056] In this embodiment, an upper armrest 21 and a side armrest 20 are provided and fixedly connected to the body sheet metal by bolts. The upper armrest 21 and the side armrest 20 provide a stable and comfortable gripping place for the driver and passengers, thereby greatly ensuring the safety of operation. The driver and passengers can easily grip the side armrest 20, and with the help of this convenient facility, smoothly pass through the chassis workbench 6 and step on the stepping assembly 1. Then, they can reach out and grab the upper armrest 21 above, and with the help of this stable support point, they can sort the items in the rear cargo box, load the goods, or check and adjust the items.

[0057] The pedal assembly 1 and the armrest assembly 2 mentioned above are optional configurations, which are designed to meet the personalized needs of different customers. Unnecessary configurations can directly save customers the corresponding costs. The avoidance groove 30 on the cab wheel cover 3 can be used to achieve convenient switching between the two configurations without the need for additional molds or additional investment, which further saves costs for customers.

[0058] Specifically, the implementation details of the structural design are as follows:

[0059] When the user does not need to install the pedal assembly 1, the wheel cover 3 of the cab remains as it is, and the avoidance groove 30 is not provided. Accordingly, the upper armrest 21, the side armrest 20, the reinforcement plate 12, the footrest 11 and the support bracket 10 and other components do not need to be assembled. In addition, the sheet metal installation holes on the cab side wall 4 will also be properly closed to maintain the integrity and aesthetics of the vehicle body.

[0060] When the user chooses to install the pedal assembly 1, the wheel cover 3 of the cab will accurately open the avoidance groove 30 to provide the necessary installation space for the pedal assembly 1. At the same time, the sheet metal on the cab side wall 4 will also be opened according to the preset position to smoothly assemble the handrail 21, the side handrail 20, the reinforcement plate 12, the footrest 11 and the support bracket 10 and other components, thereby providing the user with a convenient and safe operating experience.

[0061] In summary, a pedal assembly 1 is installed at the rear wheel arch 3 on the side of the commercial vehicle cab, and an armrest assembly 2 is arranged on the top cover, which together with the door step and the chassis workbench 6 step and the chassis workbench 6 form a set of cab rear climbing device to meet the user's cargo box maintenance needs.

[0062] The pedal assembly 1 passes through the avoidance hole of the wheel cover 3 through the support beam 100, which makes it possible to realize optional installation on the basis of the existing wheel cover 3 to meet the diverse needs of users; due to the need for optional installation, the two independent support brackets 10 of the pedal assembly 1 are first installed on the side wall 4 of the cab, and then connected through a reinforcement plate 12 to form a closed loop, and finally the foot pedal 11 is installed to achieve the characteristics of high strength and good rigidity.

[0063] The foot pedal 11 of the pedal assembly 1 can simultaneously meet the functional requirements of decoration, anti-skid, and water and mud discharge.

[0064] In the second aspect, an embodiment of the present application provides a vehicle cab, which includes: a climbing device, a cab side panel 4 and a wheel cover 3 provided in any of the above embodiments of the present application, wherein the climbing device is fixed on the cab side panel 4; and the wheel cover 3 is located at the bottom end of the climbing device.

The armrest assembly 2 can provide a gripping place to ensure safety. After the driver and passengers step on the pedal assembly 1 on the side and rear of the cab through the workbench, they can grab the armrest assembly 2 to repair and adjust the rear cargo box or top accessories.

[0066] The wheel cover 3 is provided with an avoidance groove 30 for avoiding the pedal assembly 1 .

[0067] When the user does not need to install the pedal assembly 1, the wheel cover 3 of the cab remains as it is, and the avoidance groove 30 is not provided. Accordingly, the upper armrest 21, the side armrest 20, the reinforcement plate 12, the footrest 11 and the support bracket 10 and other components do not need to be assembled. In addition, the sheet metal installation holes on the cab side wall 4 will also be properly closed to maintain the integrity and aesthetics of the vehicle body.

[0068] When the user chooses to install the pedal assembly 1, the wheel cover 3 of the cab will accurately open the avoidance groove 30 to provide the necessary installation space for the pedal assembly 1. At the same time, the sheet metal on the cab side wall 4 will also be opened according to the preset position to smoothly assemble the handrail 21, the side handrail 20, the reinforcement plate 12, the footrest 11 and the support bracket 10 and other components, thereby providing the user with a convenient and safe operating experience.
