Description

Technical Field

[0001] This utility model relates to the field of off-road vehicle pedal technology, and in particular to a pedal mechanism for a high-mobility off-road vehicle. Background Technology

[0002] In the field of high-mobility off-road vehicles, the running board, as a key auxiliary component for interaction between the vehicle and its occupants, serves the core function of providing stable support for getting in and out of the vehicle. It must also adapt to the complex conditions of off-road scenarios, including frequent bumps and vibrations, side rock scraping, and heavy-load footing. With the expanding application of high-mobility off-road vehicles in civilian off-roading, special operations, and outdoor rescue scenarios, users have placed higher demands on the practicality, ease of maintenance, and structural reliability of the running boards. These demands not only require sufficient load-bearing and impact resistance but also the ability to quickly maintain or replace the boards when wear, corrosion, or functional compatibility issues arise, minimizing vehicle downtime and ensuring operational efficiency.

[0003] The fixed pedals of existing high-mobility off-road vehicles mostly adopt an integrated mechanical structure design for the connection between the pedal surface and the pedal body. Common technical solutions include welding fixation and multi-bolt rigid connection. The welding fixation solution directly welds the metal frame of the pedal surface and the pedal body into shape, utilizing the structural strength of the weld to achieve a stable connection. The technical principle relies on the intermolecular bonding force formed by the metal fusion to ensure that the pedal surface does not shift when subjected to foot pressure or external impact. The multi-bolt rigid connection solution uses pre-matched bolt holes on the pedal surface and the pedal body, locking the two together with through bolts. The technical principle utilizes the friction and shear force generated by the axial preload of the bolts to achieve rigid fixation between the pedal surface and the body. Some solutions also add anti-loosening washers at the bolt connection points to improve connection stability under off-road bumpy conditions.

[0004] However, existing technical solutions have significant limitations, particularly in the maintenance and replacement of pedal surfaces. Because the pedal surface and the pedal body are rigidly connected by welding or multiple bolts, when the surface deforms due to off-road impacts, the anti-slip texture wears down and needs replacement, or when localized rust develops after long-term use requiring repair, the welded structure requires cutting the weld seam to separate the surface. This cutting process easily damages the metal frame of the pedal body, and subsequent re-welding requires specialized equipment and technology, making the operation difficult. While the multi-bolt connection structure eliminates the need for cutting, it requires disassembling multiple bolts one by one. Furthermore, bolts are prone to jamming due to mud and water immersion and rust in long-term off-road environments, requiring additional rust removal or the use of specialized tools. The overall process is cumbersome and time-consuming, severely impacting the efficiency of pedal maintenance and replacement, and failing to meet the rapid maintenance requirements of high-mobility off-road vehicles. Therefore, a new pedal mechanism for high-mobility off-road vehicles is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pedal mechanism for high-mobility off-road vehicles, aiming to improve the problems of existing technology where the pedal surface is mostly connected in one piece, requiring the entire pedal bracket to be disassembled for maintenance and replacement, resulting in cumbersome operation and low efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The assembly / disassembly components include a fixing sleeve and a locking block. The sidewall of the fixing sleeve is slidably connected to the inside of the pedal body and the panel. The sidewall of the locking block is slidably connected to the inside of the pedal body and the fixing sleeve. An installation sleeve is fixedly connected inside the fixing sleeve. A pull rod is slidably connected inside the installation sleeve. A fixing ring is fixedly connected to the sidewall of the pull rod. A limit rod is fixedly connected to the sidewall of the installation sleeve. The inner wall of the locking block is slidably connected to the sidewall of the limit rod. A connecting strip is rotatably connected to the sidewall of the locking block. One end of the connecting strip is rotatably connected to the sidewall of the fixing ring.

[0009] As a further description of the above technical solution:

[0010] The reinforcing component includes ribs, the sidewalls of which are fixedly connected to the inside of the pedal body, and the sidewalls of the brackets are fixedly connected to the sidewalls of the ribs.

[0012] A spring is fitted on the side wall of the pull rod. One end of the spring is fixedly connected inside the fixed sleeve, and the other end of the spring is fixedly connected to the side wall of the fixed ring.

[0013] As a further description of the above technical solution:

[0014] A triangular rib plate is fixedly connected inside the pedal body, and the side wall of the triangular rib plate is fixedly connected to the side wall of the rib.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:

[0022] A rainproof rubber cover is fixedly connected to the upper surface of the fixing sleeve, and the top of the pull rod is located inside the rainproof rubber cover.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the extension of the spring drives the fixing ring and the connecting strip to make the locking block slide into the slot of the pedal body and the fixing sleeve along the limiting rod, thereby achieving rigid fixing of the panel; when disassembling, pulling the pull rod drives the fixing ring to compress the spring, and the connecting strip pulls the locking block out of the slot to release the lock, thereby achieving the effect of quick disassembly and assembly of the panel. This solves the problem that existing fixed pedal panels are mostly integrated, and the pedal bracket needs to be completely disassembled during maintenance and replacement, which is cumbersome and inefficient. The above structure improves the convenience of panel maintenance and replacement, and reduces after-sales operation costs and time costs.

It solves the problem that the existing fixed pedal is prone to damage due to complex forces in off-road scenarios and has a bulky structure. The above structure improves the durability and vehicle adaptability of the pedal mechanism in high-mobility off-road environments. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-5 This utility model provides an embodiment of a high-mobility off-road vehicle pedal mechanism, including a bracket 1. The bracket 1 is used to fix the pedal as a whole to the side wall of the vehicle chassis, connecting the vehicle and the pedal and transmitting the load borne by the pedal. The side wall of the bracket 1 is provided with a pedal body 2, which is used to bear the stepping force and external impact, and transmit the force to the bracket 1. A panel 3 is slidably connected inside the pedal body 2. The panel 3 provides a direct stepping contact surface for the driver and passengers, and is used to bear the weight of the person and the weight of the equipment worn. Its surface is preset with anti-slip texture to improve the friction of the shoe sole and prevent slipping when getting on and off the vehicle in off-road conditions. The panel 3 is provided with a disassembly and assembly component, which is used to realize the quick locking and unlocking of the panel 3 and the pedal body 2, solving the problem of cumbersome maintenance and replacement of traditional integrated pedals. The pedal body 2 is provided with a reinforcing component, which is used to enhance the structural strength of the pedal body 2, resist the torsional force and impact force in off-road scenarios, and prevent the pedal body 2 from deforming due to heavy load or impact.

[0037] The assembly / disassembly assembly includes a fixing sleeve 4 and a locking block 8. The side wall of the fixing sleeve 4 is slidably connected to the inside of the pedal body 2 and the panel 3. By sliding the fixing sleeve 4 between the pedal body 2 and the panel 3, and cooperating with the locking action of the locking block 8, the panel 3 and the pedal body 2 can be quickly positioned and locked. The locking block 8 is used to insert into the corresponding slot of the pedal body 2, which restricts the relative displacement between the fixing sleeve 4 and the pedal body 2, thereby achieving the effect of rigidly fixing the panel 3 and the pedal body 2. The side wall of the locking block 8 is slidably connected to the inside of the pedal body 2, and the side wall of the locking block 8 is slidably connected to the inside of the fixing sleeve 4. An installation sleeve 6 is fixedly connected inside the fixing sleeve 4, and a pull rod 5 is slidably connected inside the installation sleeve 6. The pull rod 5 is used for supplying power. When an external force is applied, the sliding of the locking block 8 is triggered, thereby controlling the state of the disassembly and assembly components. A fixing ring 9 is fixedly connected to the side wall of the pull rod 5, and a limit rod 7 is fixedly connected to the side wall of the mounting sleeve 6. The limit rod 7 is used to limit the movement trajectory of the locking block 8 and prevent the locking block 8 from deviating during the sliding process. The inner wall of the locking block 8 is slidably connected to the side wall of the limit rod 7. With the pull of the connecting strip 10, the locking block 8 can be locked by extending outward and unlocked by retracting inward. A rainproof rubber cover 18 is fixedly connected to the upper surface of the fixing sleeve 4. The top of the pull rod 5 is located inside the rainproof rubber cover 18. The rainproof rubber cover 18 is used to prevent rainwater from entering the interior of the fixing sleeve 4 through the gap between the fixing sleeve 4 and the pull rod 5, which would cause the spring 11 to fail.

[0038] A connecting strip 10 is rotatably connected to the side wall of the locking block 8. The connecting strip 10 is used to connect the locking block 8 and the fixing ring 9, and plays the role of transmitting the power of the fixing ring 9, converting the axial movement of the fixing ring 9 into the lateral sliding of the locking block 8. One end of the connecting strip 10 is rotatably connected to the side wall of the fixing ring 9. A spring 11 is sleeved on the side wall of the pull rod 5. The spring 11 is made of 60Si2MnA alloy spring steel. The spring 11 is used to provide elastic potential energy. In the compressed state, it pushes the fixing ring 9 to reset, so that the locking block 8 remains in the extended and locked state. When disassembling, the spring 11 is further compressed by sliding the pull rod 5, so that the spring 11 retracts into the fixed sleeve 4, thereby achieving the unlocking effect. One end of the spring 11 is fixedly connected to the inside of the fixed sleeve 4, and the other end of the spring 11 is fixedly connected to the side wall of the fixing ring 9.

[0039] Reference Figures 6-7 The reinforcing components include ribs 12, which serve as the longitudinal load-bearing skeleton of the pedal body 2. They are used to bear the vertical stepping force transmitted by the panel 3 and directly transmit the force to the bracket 1. At the same time, they disperse the local stress in the middle of the pedal body 2, preventing the pedal body 2 from longitudinally bending and deforming due to long-term heavy load, thereby improving the longitudinal load-bearing capacity of the pedal body 2. The side wall of the rib 12 is fixedly connected to the inside of the pedal body 2. Through the rigid connection with the pedal body 2, the overall rigidity of the pedal body 2 is further strengthened. The side wall of the bracket 1 is fixedly connected to the side wall of the rib 12. Through the direct connection between the bracket 1 and the rib 12, the loss and stress concentration in the force transmission process are reduced, thereby improving the force transmission efficiency and protecting the pedal body 2.

[0040] A triangular rib plate 13 is fixedly connected inside the pedal body 2. The triangular rib plate 13 is used to enhance the connection strength between the rib 12 and the inner wall of the pedal body 2, and to prevent the connection point between the rib 12 and the pedal body 2 from loosening or breaking due to torsional force when the off-road bumps occur. This achieves the effect of resisting lateral torsional force and ensuring the stability of the structural connection. The side wall of the triangular rib plate 13 is fixedly connected to the side wall of the rib 12. Through rigid fixation with the rib 12, the longitudinal force of the rib 12 and the lateral force of the pedal body 2 are dispersed to each other, further improving the deformation resistance of the pedal body 2.

[0041] The pedal body 2 is fixedly connected with a diagonal brace 14. The diagonal brace 14 is the core component for lateral impact resistance of the pedal body 2. It is used to withstand the lateral impact force in off-road scenarios and resist the lateral pulling force generated by the pedal body 2 due to bumps. It prevents the pedal body 2 from lateral twisting or local dents, thereby enhancing the lateral impact resistance of the pedal body 2. The diagonal brace 14 is distributed in an X-shape inside the pedal body 2. The X-shaped cross structure can decompose the impact force in a single direction into two diagonal components and distribute them to the periphery of the pedal body 2 through the intersection point. Compared with straight rod support, it can transmit force more evenly, thereby improving the force distribution efficiency and reducing local stress concentration.

[0042] The pedal body 2 is equipped with a reinforcing plate 15 inside. The reinforcing plate 15 is used to fill the hollow area inside the pedal body 2, enhance the surface load-bearing capacity of the pedal body 2, and prevent the corresponding area of ​​the pedal body 2 from denting and deforming when the panel 3 is subjected to excessive local stress. This achieves the effect of improving the local compressive strength of the pedal body 2. The inner cavity of the reinforcing plate 15 has a honeycomb structure. The honeycomb structure is made of aluminum alloy. Its function is to reduce its own weight while forming a multi-node force network through multiple hexagonal units, so as to evenly distribute the local pressure to the entire reinforcing plate 15. Through the design of the honeycomb structure, it can not only meet the requirements of high-mobility off-road vehicles for pedal lightweighting, but also ensure the structural strength of the reinforcing plate 15, and avoid affecting the off-road mobility of the vehicle due to increased weight.

[0043] Two reinforcing ribs 16 are fixedly connected to the side wall of the pedal body 2. The reinforcing ribs 16 are used to strengthen the edge structure of the pedal body 2, resist the direct collision between the edge of the pedal body 2 and obstacles during off-road driving, and prevent the edge of the pedal body 2 from curling or cracking. This achieves the effect of protecting the edge of the pedal body 2 and extending its service life. It can fully cover the key areas of the pedal body 2 that are prone to collision, ensuring that there are no blind spots in edge protection.

[0044] The side wall of the pedal body 2 is fitted with a rubber sleeve 17. The rubber sleeve 17 is made of elastic rubber and serves to buffer external impacts. It also prevents the metal pedal body 2 from directly contacting external hard objects, thus avoiding wear and corrosion. It can also reduce the noise generated by stone impacts. The reinforcing rib 16 is located inside the rubber sleeve 17. By wrapping the reinforcing rib 16 with the rubber sleeve 17, the reinforcing rib 16 can be prevented from being corroded by mud and water due to exposure. When an external impact is applied to the rubber sleeve 17, the rubber sleeve 17 first absorbs part of the impact force, and the remaining impact force is borne by the reinforcing rib 16, thereby improving the overall impact resistance and wear resistance of the side wall of the pedal body 2.

[0045] Working principle: During the use of the pedal, the spring 11 is in a compressed state. The fixing ring 9 pushes the locking block 8 to slide outward along the limiting rod 7 through the connecting strip 10, so that the locking block 8 simultaneously engages in the corresponding slots of the pedal body 2 and the fixing sleeve 4. At this time, the panel 3 is rigidly fixed to the pedal body 2 through the fixing sleeve 4, realizing the stable installation of the panel 3. When it is necessary to remove the panel 3, pull the pull rod 5 upward. The pull rod 5 drives the fixing ring 9 to further compress the spring 11. The fixing ring 9 pulls the locking block 8 to slide inward along the limiting rod 7 through the connecting strip 10, so that the locking block 8 disengages from the slot of the pedal body 2. At this time, the locking between the panel 3 and the pedal body 2 is released, and the panel 3 can be slid out from the pedal body 2 to complete the disassembly.

[0046] Ribs 12 are fixed inside the pedal body 2 and directly connected to the bracket 1, forming a longitudinal load-bearing skeleton. This transfers the stepping force borne by the panel 3 to the bracket 1, dispersing local stress and preventing the pedal body 2 from deforming due to heavy load. Triangular ribs 13 are connected between ribs 12 and the inner wall of the pedal body 2. Utilizing the stability of the triangular structure, they enhance the connection rigidity between ribs 12 and the pedal body 2, resisting the torsional force generated by off-road bumps. X-shaped diagonal braces 14 form a cross-support network inside the pedal body 2, which can simultaneously withstand longitudinal and lateral impacts, such as side impacts during off-road driving, reducing the overall deformation of the pedal body 2. The honeycomb-shaped inner cavity structure of the reinforcing plate 15 reduces weight while dispersing stress through multiple hexagonal units, improving the bending resistance of the pedal body 2 and meeting the lightweight requirements of high-mobility scenarios. Two reinforcing ribs 16 enhance the impact resistance of the pedal body 2 edges. Rubber sleeves 17 wrap around the outside of the pedal body 2, buffering external impacts and preventing wear caused by direct metal-to-metal contact, thus extending service life.
