Description

Technical Field

[0001] The invention relates to the field of vehicle accessories, in particular to a motorhome step. Background Art

[0002] For off-road RVs, the chassis height is generally high, so the rear box has a large ground clearance. To facilitate boarding, a step should be provided at the door. However, the existing RV step structure is single, and when the fully fixed structure is directly retracted by flipping, it will occupy a large space on the body. When the fully foldable step is used for a long time, it is difficult to ensure the stability of the structure.

[0003] At present, a Chinese patent application with publication number CN113734051A and publication date December 3, 2021 proposes a hidden automatic step and control system for commercial vehicles. The automatic step includes: an operating box for fixing to the vehicle chassis, the operating box having a first footrest surface; a flip pedal hinged to the side of the operating box away from the first footrest surface; and a telescopic pedal located on the side of the flip pedal away from the operating box.

[0004] When in use, the first driving mechanism can drive the flip pedal to rotate around the axis of the hinge until it is hidden in the operating box, and the first driving mechanism can drive the flip pedal to rotate around the axis to the outside of the operating box, so that the flip pedal is parallel to the first footrest surface; the second driving mechanism can drive the telescopic pedal to retract into the operating box, and when the flip pedal is parallel to the first footrest surface, the second driving mechanism can drive the telescopic pedal to extend to be arranged in a stepped manner with the flip pedal.

[0005] Regarding the above-mentioned related technologies, when the automatic pedal is unfolded and used, the flip pedal and the telescopic pedal are connected only by multiple folding rods in the second drive mechanism, and the flip pedal and the telescopic pedal have no support in the horizontal direction, which causes the automatic pedal to shake easily during use and has poor stability. Summary of the invention

[0006] In order to improve the stability of the foldable step and enhance the user experience, the present invention provides a motorhome step.

[0007] The present invention provides a motorhome step, which adopts the following technical solution: A motorhome step comprises a frame, a flip step and a driving mechanism, wherein the flip step is rotatably connected to the frame, the driving mechanism is installed on the frame, and the driving mechanism is transmission-connected to the flip step, a plurality of first pedals are fixedly arranged on the flip step, and the plurality of first pedals are arranged in a step-like manner; a sliding step is also slidably arranged on the flip step, and a second pedal is fixedly arranged on the sliding step; when the motorhome step is folded, the sliding step slides along the flip step to a first extreme position, at which time the flip step and the sliding step are both stored inside the frame; when the motorhome step is unfolded, the sliding step slides along the flip step to a second extreme position, at which time the flip step and the sliding step are unfolded outside the frame, and a plurality of the first pedals and the second pedals are arranged in a step-like manner.

[0008] By adopting the above technical solution, when the RV step is unfolded, first the driving mechanism drives the flip step to rotate toward the outside of the frame, and the flip step flips out of the frame to form a fixed step, and then the sliding step on the flip step extends out and slides to the bottom to reach the second extreme position, at which time the first pedal on the flip step and the second pedal on the sliding step are both in a fixed position, and the first pedals and the second pedals are arranged in a stepped shape as a whole; when the RV step is folded, first the sliding step slides toward the flip step and slides to the position where the second pedal fits under the first pedal to reach the first extreme position, and then the driving mechanism drives the sliding step and the flip step to rotate together and be stored inside the frame. In this way, when the chassis of the vehicle is high, the flip step and the sliding step can be used together to increase the height of the step, making it easier for users to get on the vehicle; and when storing, the sliding step and the flip step are folded and then stored in the frame uniformly, reducing the space occupied by the vehicle when the step is stored; at the same time, setting the flip step as a structure with multiple pedals fixed can effectively improve the stability of the step.

[0009] Optionally, the flip step further includes two first side panels, the two first side panels are rotatably connected to the frame, and the plurality of first pedals are fixedly mounted between the two first side panels.

[0010] By adopting the above technical solution, multiple first pedals are fixed between the two first side plates, so that the first side plates and the multiple first pedals are fixedly connected to form a rigid frame, which can reduce shaking or deformation caused by moving parts; at the same time, the first pedal is fixed between the two first side plates, and when the first pedal is under pressure, it is evenly transmitted to the frame through the two first side plates, effectively dispersing the load and improving the overall stability of the flip step.

[0011] Optionally, the two side edges of the first side panel are vertically arranged, and a mounting hole is arranged at the intersection of the two mutually perpendicular side edges of the first side panel; a connecting plate is arranged at the bottom of the frame, and the connecting plate is arranged at the edge position of the frame, and the connecting plate is rotatably connected to the first side panel through the mounting hole.

[0012] By adopting the above technical solution, when the flip step is unfolded, the first side plate rotates around the connecting plate around the position of the mounting hole, and the first pedal is rotated to a position outside the frame, at which time one of the right-angled sides of the first side plate is parallel to the vertical edge of the frame, the other right-angled side of the first side plate is located outside the frame and parallel to the bottom edge of the frame, and the first pedal is located in a horizontal position; when the flip step is folded, the first side plate rotates around the connecting plate in the opposite direction around the position of the mounting hole, and the hypotenuse of the first side plate is rotated to a position inside the frame, at which time one of the right-angled sides of the first side plate is parallel to the vertical edge of the frame, the other right-angled side of the first side plate is located inside the frame and parallel to the bottom edge of the frame. In this way, the rotational connection between the flip step and the frame is realized, and the flip step is set as an integral fixed structure, so that the overall unfolding and folding storage of the flip step is realized, and the stability of the step is effectively improved.

[0013] Optionally, a limit assembly is also included, which includes a limit block and a limit plate, wherein the limit block is arranged on the vertical edge of the frame, and the limit block is arranged above the connecting plate; the limit plate is arranged on one of the right-angled edges of the first side plate; when the RV step is unfolded, the limit plate abuts against the limit block to limit the flip step.

[0014] By adopting the above technical solution, when the RV step is unfolded, the flip step rotates around the mounting hole, and when the flip step rotates to a horizontal position of the first pedal, one of the vertical sides of the first side plate is parallel to the vertical side of the frame, and the limit plate installed on the vertical side of the first side plate abuts against the limit block on the vertical side of the frame, and the limit block and the limit plate cooperate to limit the flip step to the extreme position of the unfolded state. In this way, when the RV step is unfolded and used, the flip step is limited to the extreme position, thereby improving the stability of the flip step during use.

[0015] Optionally, the limiting assembly also includes an abutment rod, which is fixedly arranged at the bottom of the frame and is arranged axially along the mounting hole; the first side panel is provided with a groove on the right-angled side of the limiting plate; when the flip step is folded, the groove abuts against the abutment rod to limit the flip step.

[0016] By adopting the above technical solution, when the RV step is folded, the flip step rotates in the opposite direction around the mounting hole, and when the flip step rotates to be completely folded inside the frame, the vertical edge of the first side panel provided with the groove rotates to the inside of the frame, and the vertical edge of the first side panel provided with the groove is parallel to the bottom edge of the frame, and the groove provided on the vertical edge is clamped in the abutment rod provided at the bottom of the frame, and the abutment rod and the groove cooperate to limit the flip step to the extreme position of the folded state. In this way, when the RV step is folded, the flip step is folded in the frame, and the abutment rod and the groove cooperate to limit the flip step to the extreme position of the folded state, which can effectively improve the stability of the flip step when it is folded.

[0017] Optionally, the sliding step further includes two second side panels, the two second side panels are respectively slidably arranged on the outsides of the two first side panels, and the second pedal is fixedly installed between the two second side panels.

[0018] By adopting the above technical solution, when the sliding step is extended, the second side panel slides downward along the first side panel, and when the first side panel slides to the bottom, it reaches the second extreme position, at which time the second pedal and the first pedal are in a step-like shape, and the position of the sliding step is fixed; when the sliding step is folded, the second side panel slides in the opposite direction, and when the sliding step slides until the second pedal is attached to the bottom of the first pedal, it reaches the first extreme position, at which time the sliding step and the flip step are stored together inside the frame; the second pedal is fixedly set between the two second side panels, and the load-bearing force of the second pedal can be transmitted to the second side panels on both sides, thereby increasing the stability of the sliding step. In this way, when the sliding step is extended, the overall height of the RV step can be increased, providing convenience for the user; when the sliding step is folded, the overall storage space of the RV step can be reduced, and at the same time, setting the sliding step as an overall fixed structure can also increase the overall stability of the sliding step.

[0019] Optionally, a plurality of sliding columns are provided on the outer side surface of the first side panel; a long hole is provided on the second side panel, and the plurality of sliding columns are slidably provided in the long hole; when the RV step is folded, the second side panel slides to the first extreme position along the direction of the long hole under the action of gravity; when the RV step is unfolded, the second side panel slides to the second extreme position along the direction of the long hole under the action of gravity.

[0020] By adopting the above technical solution, when the long hole on the second side panel slides along the sliding column, the second side panel slides along the direction of the long hole outside the first side panel, and in the process of the flip step flipping to be stored inside the frame, the direction of the long hole rotates relative to the bottom surface, and when the long hole rotates to a certain angle with the horizontal plane, the second side panel slides along the direction of the long hole under the action of gravity, and slides to the first extreme position, so as to realize the folding and storage of the sliding step and the flip step; when the flip step flips to be unfolded outside the frame, the second side panel slides toward the other end along the direction of the long hole under the action of gravity, and slides to the position extending from the first side panel at the second extreme position, so as to realize the unfolding of the sliding step and the flip step. In this way, by setting a plurality of sliding columns and long holes distributed in an inclined manner, the sliding step can slide automatically under the action of gravity, and the flip step can slide, fold and unfold automatically under the action of gravity during the rotation of the flip step, without human intervention.

[0021] Optionally, a limiting hole is also provided at the end of the second side panel, and the limiting hole is provided at an end away from the second pedal; an electronic plug is also installed at the bottom of the frame, and the electronic plug is arranged toward the inside of the frame; when the RV step is folded, the electronic plug extends out and is plugged into the limiting hole to lock the flip step and the sliding step.

[0022] By adopting the above technical solution, when the flip step is folded in the frame, the sliding step slides in the direction of the long hole under the action of gravity. When the flip step is supported on the abutment rod, the sliding step also slides to the first limit position under the action of gravity and is folded in the frame together with the flip step. At this time, the limit hole set on the second side plate of the sliding step corresponds to the position of the electronic plug. After the electronic plug pops out, it is plugged into the limit hole of the second side plate, limiting the sliding step and the flip step together to the limit position of the folded state. In this way, the coordinated setting of the electronic plug and the limit hole can lock the flip step and the sliding step in the folded state, reduce the probability of the flip step and the sliding step shaking in the frame after the RV step is folded, and further improve the stability of the anti-skid step in the folded state.

[0023] Optionally, the first side plate and the second side plate are both provided with weight-reducing holes, and the sliding column can be adjusted in tightness to adjust the sliding speed of the sliding step.

[0024] By adopting the above technical solution, the setting of the weight-reducing holes effectively reduces the weight of the flip step and the sliding step, thereby reducing the requirement for the driving force of the driving mechanism, while also satisfying the lightweight setting of the overall structure.

[0025] At the same time, when the sliding column slides in the long hole, after the sliding column is tightened, the sliding column is pressed against the second side plate, thereby increasing the sliding friction between the second side plate and the first side plate, slowing down the sliding speed of the sliding step; when the sliding column is loosened, the pressure of the sliding column on the second side plate is reduced, thereby reducing the sliding friction between the second side plate and the first side plate, and accelerating the sliding speed of the sliding step. When the sliding column is tightened, the sliding speed of the sliding step is reduced, thereby reducing the impact on the sliding column when the sliding step slides to the extreme position, and extending the service life of the overall structure; loosening the sliding column makes the sliding speed of the sliding step faster, which can effectively shorten the unfolding and folding time of the sliding step. By adjusting the tightness of the sliding column, the user can control the sliding speed of the sliding step according to his own habits, thereby improving the user experience.

[0026] Optionally, the driving mechanism is an electric push rod, a first mounting plate is provided on the frame, and one end of the electric push rod is rotatably connected to the first mounting plate; a second mounting plate is also provided at the bottom of one of the first pedals, and the other end of the electric push rod is rotatably connected to the other end of the second mounting plate.

[0027] By adopting the above technical solution, when the electric push rod is extended, the extended end of the electric push rod pushes the first pedal to rotate around the mounting hole, and the first pedal drives the flip step to rotate around the mounting hole to the outside of the frame, and unfolds the flip step; when the electric push rod is shortened, the extended end of the electric push rod retracts and pulls the first pedal to rotate around the mounting hole, and the first pedal drives the flip mechanism to rotate around the mounting hole to the inside of the frame, and folds the flip step in the frame; during the extension or shortening of the electric push rod, the two ends of the electric push rod rotate relative to the first mounting plate and the second mounting plate respectively. Such an electric push rod setting provides a solution for the automatic flipping of the flip step, and cooperates with the sliding of the sliding step under the action of gravity to realize the automatic unfolding and folding of the RV step, thereby improving the automation and intelligence of the RV step and making it more convenient to use.

[0028] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The RV steps are set to be a flip step with a fixed overall structure plus a sliding step structure that can slide and fold. This combines the advantages of the fixed step structure being stable and the folding step being easy to store. It provides multiple steps while having the advantages of stability and easy storage.

[0029] 2. The sliding step in the present application is stored in a sliding and folding manner, and the sliding step can slide, unfold and fold automatically under the action of gravity during the process of turning the step, without the need for manual control, thereby increasing portability.

[0030] 3. A sliding column capable of adjusting the tightness is provided at the sliding connection between the flip step and the sliding step, and the sliding speed of the sliding step is adjusted thereby, so that the user can control the sliding speed of the sliding step according to his own habits, thereby improving the user experience.

[0031] 4. By setting a limit component on the frame, the unfolded state and the folded state of the flip step and the sliding step are limited, thereby increasing the stability of the RV steps after unfolding or folding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following combination Figures 1 to 10 The present invention is described in further detail.

When the motorhome step is unfolded and used, the driving mechanism 400 first drives the flip step 200 to flip out of the frame 100, and supports the unfolded flip step 200 through a limiting component. During the process of the flip step 200 flipping out, the sliding step 300 slides and unfolds under the action of gravity; when the motorhome step is folded, the driving mechanism 400 first drives the flip step 200 to rotate and be stored inside the frame 100, and supports the flip step 200 inside the frame 100 through the limiting component. During the process of the flip step 200 flipping into the frame 100, the sliding step 300 slides to the other side under the action of gravity, and gradually overlaps with the flip step 200 and is stored in the frame 100.

[0036] The RV step adopts an overall structure of a combination of a flip step 200 and a sliding step 300. The flip step 200 is provided with a plurality of fixed pedals, and the sliding step 300 can be slid and folded on the flip step 200, combining the stable structure of the fixed step and the easy storage of the folding step, thereby providing a plurality of steps while reducing the occupied storage space.

[0037] Reference Figures 4 to 5The frame 100 includes a first frame 130, a second frame 140 and a connecting pipe 150, wherein the first frame 130 includes two first transverse pipes 131 and two first longitudinal pipes 132, and the second frame 140 includes two second transverse pipes 141 and two second longitudinal pipes 142, and the two frames 100 have the same structure. The two frames 100 are connected by a plurality of connecting pipes 150, and when the flip step 200 and the sliding step 300 are flipped and stored, the flip step 200 and the sliding step 300 can be accommodated inside the frame 100; two limit blocks 102 are fixedly provided at the upper position of the edge of the opposite side of the first frame 130 and the second frame 140, and when the flip step 200 is flipped out to a horizontal position, the limit blocks 102 are used to limit the flip step 200; two connecting plates 101 are fixedly provided at the bottom edge of the opposite side of the first frame 130 and the second frame 140, and the flip step 200 is connected to the frame 100 through the connecting plates 101. Rotational connection; an abutment rod 110 is also fixedly provided in the middle position at the bottom of the frame 100, one end of the abutment rod 110 is fixedly provided in the middle position at the bottom of the first frame 130, and the other end is fixedly provided in the middle position at the bottom of the second frame 140, and a first mounting plate 111 is also fixedly provided in the middle of the abutment rod 110, and the first mounting plate 111 is rotationally connected to the fixed part 410 of the driving mechanism 400; an electronic latch 120 is fixedly provided on the first transverse tube 131 at the lower part of the first frame 130, and when the flip step 200 is flipped back into the frame 100, the electronic latch 120 can lock the flip step 200.

[0038] Preferably, a reinforcing tube 160 is provided between the two longitudinal tubes of the first frame 130 and between the two longitudinal tubes of the second frame 140 , so as to further enhance the stability of the frame 100 .

[0039] Reference Figure 6 to Figure 7The flip step 200 includes a first side plate 210 and a first pedal 220, and the flip step 200 is rotatably connected to the frame 100. The first side plates 210 are a pair and are integrally formed. The first side plates 210 are in a right-angled triangle structure as a whole, and a mounting hole 212 is provided at a right angle position of the first side plate 210. The first side plate 210 is rotatably connected to the connecting plate 101 of the frame 100 through the mounting hole 212; two pairs of sliding columns 211 are installed on the first side plate 210, and each pair includes at least two linearly distributed sliding columns 211. The sliding columns 211 are slidably connected to the sliding step 300, and the sliding columns 211 can adjust the tightness, thereby controlling the sliding speed of the sliding step 300; a limiting plate 213 is fixedly provided on the top end of the outer side of the first side plate 210. When the flip step 200 is flipped out of the frame 100 and the first pedal 220 is in a horizontal position, the limiting plate 213 and the frame 100 are in a horizontal position. The limit block 102 abuts to limit the flip step 200; a groove 214 is also provided at the rear of the first side plate 210, and the groove 214 is arranged at a position between the limit plate 213 and the mounting hole 212, and the distance from the groove 214 to the mounting hole 212 is the same as the distance from the abutment rod 110 to the mounting hole 212. When the flip step 200 flips into the interior of the frame 100, the groove 214 cooperates with the abutment rod 110 in the middle of the lower part of the frame 100 to limit the position of the flip step 200; there are three first pedals 220 fixed in a stepped shape between the two first side plates 210, and a second mounting plate 221 is also fixed at the bottom of the lowest first pedal 220, and the second mounting plate 221 is used to connect the other end of the driving mechanism 400.

[0040] Preferably, a weight-reducing hole 215 is opened on the first side plate 210 , so as to achieve lightweight overall structure and reduce the driving force requirement for the driving mechanism 400 .

[0041] Reference Figures 8 to 9 The sliding step 300 includes a second side plate 310 and a second pedal 320, and the sliding step 300 is slidably connected to the flip step 200. The second side plates 310 are a pair and are integrally formed. Two parallel long holes 311 are opened on the second side plates 310. The long holes 311 serve as sliding tracks for matching with the sliding posts 211 on the flip step 200. Each long hole 311 corresponds to a pair of sliding posts 211, and the extension direction of the long holes 311 is consistent with the distribution direction of each pair of sliding posts 211; a limiting hole 312 is opened on the top of the outer side of the second side plate 310. When the sliding step 300 is stored in the frame 100, the position of the limiting hole 312 corresponds to the position of the electronic plug 120; the second pedal 320 is fixed between the two second side plates 310, and the second pedal 320 is arranged parallel to the first pedal 220.

[0042] During the process of the flip step 200 flipping into the frame 100, the sliding step 300 slides along the long hole 311 due to the action of gravity. When the flip step 200 is completely flipped into place, the sliding step 300 slides to the first extreme position. At this time, the electronic plug 120 extends out and inserts into the limit hole 312, locking the two steps inside the frame 100; during the process of the flip step 200 flipping out of the frame 100, the sliding step 300 slides along the long hole 311 due to the action of gravity. When the flip step 200 is completely flipped into place, the sliding step 300 slides to the second extreme position. At this time, the second pedal 320 serves as the bottom step.

[0043] Preferably, a weight-reducing hole 215 is opened on the second side plate 310 , so as to achieve lightweight overall structure and reduce the driving force requirement for the driving mechanism 400 .

[0044] Reference Fig.10 The driving mechanism 400 includes a fixed portion 410 and a telescopic portion 420. The fixed portion 410 is hinged on the first mounting plate 111 of the frame 100, and the telescopic portion 420 is hinged on the second mounting plate 221 of the flip step 200. By extending and shortening the driving mechanism 400, the flip step 200 can be controlled to flip outward or inward.

[0045] Preferably, the driving mechanism 400 may be an electric push rod.

[0046] The implementation principle of a motorhome step in an embodiment of the present invention is as follows: when the motorhome step is unfolded and used, the driving mechanism 400 drives the flip step 200 to rotate toward the outside of the frame 100. When the flip step 200 rotates to a position where the first pedal 220 is horizontal, the limit plate 213 provided on the flip step 200 abuts against the limit block 102 on the frame 100 and limits the flip step 200 to the current position. During the rotation of the flip step 200, the sliding step 300 will slide along the direction of the long hole 311 under the action of gravity, and reach the limit position and be fully unfolded when sliding to the lowest position; when the motorhome step is folded, the driving mechanism 400 drives the flip step 200 toward the frame 10 0, when the flip step 200 rotates to the vertical position of the first pedal 220, the groove 214 provided on the first side plate 210 abuts against the abutting rod 110 provided at the bottom of the frame 100, and limits the flip step 200 to the current position. During the rotation of the flip step 200, the sliding step 300 will slide to the other end along the long hole 311 under the action of gravity, and reach the limit position when sliding to the lowest position. At this time, the limiting hole 312 provided on the second side plate 310 corresponds to the position of the electronic plug 120 installed on the frame 100, and the electronic plug 120 pops out and plugs into the limiting hole 312 to lock the sliding step 300 and the flip step 200.

[0047] To summarize, in the present application, the structure of a three-step fixed flip step 200 and a one-step sliding step 300 can reduce the space occupied in the vehicle while achieving a four-step step; the three-step fixed flip step 200 adopts an integral structure, which improves the stability of the overall structure; the one-step sliding step 300 is retracted and extended by gravity, and the sliding speed of the sliding step 300 can be controlled by adjusting the tightness of the sliding columns 211 on both sides, thereby improving the convenience of use; the multiple limit assemblies arranged on the frame 100 can improve the stability of the RV steps when they are unfolded for use or folded for storage.

[0048] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
