Description

Technical Field

[0001] This utility model relates to the field of mechanical dog transportation technology, specifically a vehicle-mounted hidden lifting platform with a five-stage folding and flipping pedal. Background Technology

[0002] Robotic dogs typically employ multi-legged or quadrupedal locomotion structures, relying on the flexion and extension of their leg joints to move. However, their vertical range of motion is limited, and their ground stability depends on the full contact between their feet and the contact surface. When there is a certain height difference between the vehicle and the ground, such as the height of the cargo bed of a regular truck or off-road vehicle, the robotic dog cannot directly step onto or jump off like a human or wheeled equipment. Otherwise, it may lose its center of gravity, fall, or even damage its joint components due to insufficient leg extension. Therefore, ladders are needed to form connecting channels for the robotic dog to move onto and off the vehicle.

[0003] Existing vehicle ladders, especially those used in vehicles, are typically folded and stored manually. When in use, they must be manually removed from their storage location and secured under the vehicle door. This requires manual handling each time they are used, which is inconvenient.

[0004] Therefore, this utility model provides a vehicle-mounted hidden lifting platform with a five-stage folding and flipping pedal to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing vehicle-mounted ladders require manual operation and are inconvenient to use.

[0006] This utility model provides the following technical solution: a vehicle-mounted concealed lifting platform with a five-stage folding and flipping pedal, comprising a mechanical dog, folding pedals, a lifting platform, and a carrier. The carrier has a receiving space, within which the lifting platform for housing the mechanical dog is installed. A folding pedal, hinged to the side of the lifting platform, facilitates the mechanical dog's movement onto and off the vehicle. The folding pedal forms a stepped structure through multiple folds, allowing the mechanical dog to move onto and off the vehicle. The mechanical dog can move out of the carrier from within the lifting platform using the folding pedals. Conversely, the mechanical dog can also enter the lifting platform via the folding pedals, and then the lifting platform lowers to store the mechanical dog.

[0007] As one embodiment of this utility model, the folding pedal includes a drive assembly and a body. The drive assembly is mounted on the side of the lifting platform, and the end of the drive assembly is hinged to the body. The body is composed of a horizontal bar and a vertical bar that are hinged to each other.

[0008] As one possible embodiment of this invention, the drive assembly causes the two ends of the horizontal and vertical bars to swing around the hinge point, thereby enabling the hinged horizontal and vertical bars to form a stepped structure to accommodate the mechanical dog for moving and loading.

[0009] As one option of this utility model, multiple horizontal and vertical segments are hinged to each other and connected end to end to form a multi-level stepped structure.

[0010] As one option of this utility model, the bottom of the multi-level stepped structure is a grounding tread, and the end of the vertical rod in the grounding tread is hinged to the middle of the horizontal rod.

[0011] In one embodiment of this invention, the end of the vertical rod in the lowest grounding pedal is hinged to the middle of the horizontal rod, so that after the hinged horizontal and vertical rods are rotated and unfolded, half of the horizontal rod forms a horizontal step for the mechanical dog to move on.

[0012] As one option of this utility model, the upper part of the grounding pedal is a movable pedal, and the middle part of the vertical bar in the movable pedal is hinged to the middle part of the horizontal bar to form an X-shaped structure. Then, after rotation and unfolding, half of the horizontal bar forms a pedal step that allows the mechanical dog to move.

[0013] As one embodiment of this utility model, the driving assembly includes a pedal electric cylinder, the two ends of which are respectively hinged to a crossbar and a vertical bar, thereby driving the crossbar and vertical bar to swing around the hinge point to expand into steps or retract for storage.

[0014] As one embodiment of this utility model, the drive assembly further includes a tilting electric cylinder, a floating joint fixing seat, a rack, a sliding guide rail, and a gear. The tilting electric cylinder is fixedly installed on the inner surface of the carrier via an electric cylinder connecting plate. A floating joint fixing seat is fixedly installed at one end of the tilting electric cylinder. A rack is fixedly installed at the other end of the floating joint fixing seat. A sliding guide rail for accommodating the movement of the rack is fixedly installed on the inner surface of the carrier. A rack is hinged inside the carrier. A pedal electric cylinder and one end of a crossbar are coaxially fixed to the rack in sequence. The other end of the pedal electric cylinder is hinged to one end of a longitudinal rod.

[0015] As one possible embodiment of this utility model, the flipping electric cylinder drives the floating joint fixing seat and the rack to move horizontally and drive the gear to rotate, thereby driving the pedal electric cylinder and the end of the crossbar to rotate along the gear axis to unfold or retract.

[0016] As one option of this utility model, a flip-up door is rotatably installed inside the vehicle, and the folding pedal is installed on the surface of the flip-up door.

[0017] The flip door rotates, causing the drive assembly to rotate, and in conjunction with the rotation of the drive assembly, it completes the storage or unfolding process.

[0018] As one embodiment of this utility model, the lifting platform includes a lifting guide rail, a slider, a lifting pedal, and a lifting electric cylinder. The lifting guide rail is symmetrically and vertically fixedly installed inside the carrier. The slider is slidably installed on the surface of the lifting guide rail. A lifting pedal is fixedly installed between the two sliders. The lifting electric cylinder is fixedly installed above the lifting guide rail.

[0019] The beneficial effects of this utility model are as follows: This invention utilizes a lifting platform to easily accommodate and conceal the mechanical dog, making it convenient to carry and use without taking up trunk space. Furthermore, the automatic folding of the drive assembly and the main body forms steps for the mechanical dog to move, reducing operational difficulty and improving portability.

[0027] In response to the inconvenience of manual operation required for existing vehicle-mounted ladders, such as Figures 1 to 6 As shown, this embodiment of the present disclosure provides a vehicle-mounted hidden lifting platform with a five-level folding and flipping pedal, including a mechanical dog 11, a folding pedal 2, a lifting platform 3, and a carrier 4. The carrier 4 is provided with a accommodating space, and the lifting platform 3 for accommodating the mechanical dog 1 is installed in the accommodating space. The folding pedal 2 for accommodating the mechanical dog 1 to move up and down the vehicle is hinged to the side of the lifting platform 3. The folding pedal 2 forms a stepped structure through multi-level folding to accommodate the mechanical dog 1 to move up and down the vehicle.

[0028] like Figures 1 to 3As shown, the mechanical dog 1 is transported to a designated position via the carrier 4. Then, the lifting platform 3 lifts the mechanical dog 1 up until it is level with the folding pedal 2, allowing the mechanical dog 1 to move away from the carrier 4 via the folding pedal 2 within the lifting platform 3. Conversely, the mechanical dog 1 can also enter the lifting platform 3 via the folding pedal 2, and then the lifting platform 3 lowers to store the mechanical dog 1.

[0029] It should be noted that the vehicle 4 can be any existing equipment with transportation capabilities, such as automobiles, drones, or ships. In this embodiment, an existing automobile is used for transportation.

[0030] like Figure 4 and 5 As shown, the folding pedal 2 includes a drive assembly 21 and a body 22. The drive assembly 21 is installed on the side of the lifting platform 3. The end of the drive assembly 21 is hinged to the body 22. The body 22 is composed of a horizontal bar 221 and a vertical bar 222 that are hinged to each other.

[0031] like Figure 4 and 5 As shown, the drive assembly 21 drives the two ends of the horizontal bar 221 and the vertical bar 222 to swing around the hinge point, so that the horizontal bar 221 and the vertical bar 222, which are hinged to each other, can form a stepped structure to accommodate the mechanical dog 1 for moving and loading the loading and unloading device 4.

[0032] like Figure 4 and 5 As shown, multiple horizontal bars 221 and vertical bars 222 are hinged to each other and connected end to end to form a multi-level stepped structure. The multi-level stepped structure allows the mechanical dog 1 to enter or leave the vehicle 4 at excessively high or different heights, thereby further facilitating the mechanical dog 1 to enter or leave the vehicle 4, and allowing the number of stepped segments of the body 22 to be adjusted according to the height of the vehicle 4.

[0033] like Figure 4 and 5 As shown, in this embodiment, a five-step structure is formed, namely, five folding pedals 2 to accommodate the mechanical dog 1 moving onto and off the vehicle 4. The specific number of steps can be set or improved according to the height of the vehicle 4 and the range of motion of the mechanical dog 1's feet, which will not be elaborated further.

[0034] like Figure 4 As shown, the bottom of the multi-level stepped structure body 22 is a grounding pedestal 223, and the end of the vertical rod 222 in the grounding pedestal 223 is hinged to the middle of the horizontal rod 221.

[0035] like Figure 4As shown, the end of the vertical rod 222 in the lowest grounding pedal 223 is hinged to the middle of the horizontal rod 221, so that after the horizontal rod 221 and the vertical rod 222 are rotated and unfolded, half of the horizontal rod 221 forms a horizontal pedal step that allows the mechanical dog 1 to move.

[0036] Above the grounding pedal 223 is the movable pedal 224. The middle part of the vertical rod 222 in the movable pedal 224 is hinged to the middle part of the horizontal rod 221, thereby forming an X-shaped structure. After being rotated and unfolded, half of the horizontal rod 221 forms a step for the mechanical dog 1 to move. Furthermore, the movable pedal 224 and the grounding pedal 223 cooperate with each other, so that the mechanical dog 1 can enter the lifting platform 3 in the carrier 4 from the ground or other reference point, such as a platform, through the movable pedal 224 and the grounding pedal 223, and complete the storage by lifting the lifting platform 3.

[0037] like Figure 4 and 5 As shown, the drive assembly 21 includes a pedal cylinder 211. The two ends of the pedal cylinder 211 are hinged to the crossbar 221 and the vertical bar, respectively. Thus, the two ends of the pedal cylinder 211 drive the crossbar 221 and the vertical bar to swing around the hinge point to expand and form steps or retract for storage.

[0038] During the process of the drive assembly 21 unfolding the drive body 22 to form a staircase, the pedal cylinder 211 is activated to extend and retract, thereby causing the ends of the uppermost horizontal bar 221 and vertical bar 222 to swing along the central hinge point, and causing the ends of multiple sets of horizontal bars 221 and vertical bars 222 connected end to end to swing synchronously along the central hinge point, thereby forming a multi-level staircase structure, which in turn accommodates the movement of the mechanical dog 1.

[0039] like Figure 4 and 5 As shown, the drive assembly 21 also includes a tilting electric cylinder 212, a floating joint fixing seat 213, a rack 214, a sliding guide rail 215, and a gear 216. The tilting electric cylinder 212 is fixedly installed on the inner surface of the carrier 4 through the electric cylinder connecting plate. The floating joint fixing seat 213 is fixedly installed at one end of the tilting electric cylinder 212. The rack 214 is fixedly installed at the other end of the floating joint fixing seat 213. The sliding guide rail 215, which accommodates the movement of the rack 214, is fixedly installed on the inner surface of the carrier 4. The rack 214 is hinged inside the carrier 4. The rack 214 is coaxially fixed with one end of the pedal electric cylinder 211 and the crossbar 221. The other end of the pedal electric cylinder 211 is hinged to one end of the longitudinal bar.

[0040] Before or after the main body 22 unfolds to form a stepped structure, the flipping electric cylinder 212 is activated, which drives the floating joint fixing seat 213 and the rack 214 to move horizontally along the sliding guide rail 215. The horizontal movement of the rack 214 drives the gear 216 to rotate, and the rotating gear 216 drives the pedal electric cylinder 211 and the end of the crossbar 221 to rotate along the axis of the gear 216, thereby completing the process of storing into or leaving the interior of the carrier 4 in preparation for unfolding.

[0041] It should be noted that the carrier 4 can mount the gear 216 using any existing structure, such as a fixed shaft.

[0042] Both the tilting electric cylinder 212 and the pedal electric cylinder 211 can be existing pneumatic or hydraulic cylinders with linear telescopic function.

[0043] like Figure 2 and 3 As shown, a flip door 23 is rotatably installed inside the vehicle 4, and the folding pedal 2 is installed on the surface of the flip door 23.

[0044] like Figures 1 to 3 As shown, before or after the mechanical dog 1 is moved by the drive assembly 21, the flip door 23 rotates, thereby driving the drive assembly 21 to rotate and cooperating with the rotation of the drive assembly 21 to complete the storage or unfolding.

[0045] It should be noted that the driving method of the flip door 23 can be driven by any existing method, such as motor drive and power supply in the carrier 4. The method of driving the flip door 23 to rotate is a very mature existing technology, which will not be elaborated on here.

[0046] like Figures 1 to 3 As shown, it should also be noted that the drive component 21 drives the body 22 to rotate, and the flip door 23 drives the drive component 21 and the body 22 to rotate, thereby completing the storage or unfolding.

[0047] like Figure 6 As shown, the lifting platform 3 includes a lifting guide rail 31, a slider 32, a lifting pedal 33, and a lifting cylinder 34. The lifting guide rail 31 is symmetrically and vertically fixedly installed inside the carrier 4. The slider 32 is slidably installed on the surface of the lifting guide rail 31. A lifting pedal is fixedly installed between the two sliders 32. The lifting cylinder 34 is fixedly installed above the lifting guide rail 31.

[0048] During the process of the mechanical dog 1 entering the lifting platform 3 from the main body 22 or entering the main body 22 from the lifting platform 3, the lifting electric cylinder 34 is activated to drive the slider 32 to move longitudinally along the surface of the lifting guide rail 31, thereby driving the lifting pedal 33 to carry the mechanical dog 1 to move longitudinally, thus completing the storage or transportation of the mechanical dog 1.

[0049] During the process of transporting the mechanical dog 1, the lifting electric cylinder 34 is activated, which drives the slider 32 to move longitudinally upward along the surface of the lifting guide rail 31, thereby driving the lifting pedal 33 to carry the mechanical dog 1 to move longitudinally upward and become flush with the body 22. At the same time as the lifting pedal 33 moves upward or after the lifting pedal 33 moves upward, the flip door 23 drives the drive assembly 21 and the body 22 to rotate. Then, the flip electric cylinder 212 is activated, which drives the floating joint fixing seat 213 and the rack 214 to move horizontally along the sliding guide rail 215. Thus, the horizontal movement of the rack 214 drives the gear 216 to rotate, and then the rotating gear 216 drives the pedal electric cylinder 211 and the end of the crossbar 221 to rotate along the axis of the gear 216. Then, the pedal cylinder 211 is activated to extend and retract, thereby causing the ends of the uppermost horizontal bar 221 and vertical bar 222 to swing along the central hinge point, and causing the ends of multiple sets of horizontal bars 221 and vertical bars 222 connected end to end to swing synchronously along the central hinge point, thus forming a multi-level stepped structure, which in turn accommodates the movement of the mechanical dog 1.

[0050] During the retrieval of the mechanical dog 1, after the main body 22 forms a multi-level stepped structure, the mechanical dog 1 moves along the main body 22 into the lifting pedal 33. Then, the lifting electric cylinder 34 is activated to drive the slider 32 to move longitudinally downward along the surface of the lifting guide rail 31, thereby driving the lifting pedal 33 to carry the mechanical dog 1 to move longitudinally downward for storage. At the same time or after storage, the pedal electric cylinder 211 is activated to retract, thereby driving the ends of the uppermost horizontal bar 221 and vertical bar 222 to swing along the middle hinge point, and driving the ends of multiple sets of horizontal bars 221 and vertical bars 222 connected end to end to swing synchronously along the middle hinge point for storage. Subsequently, the flipping electric cylinder 212 is activated, causing the floating joint fixing seat 213 and the rack 214 to move horizontally along the sliding guide rail 215. The horizontal movement of the rack 214 drives the gear 216 to rotate, which in turn drives the pedal electric cylinder 211 and the end of the crossbar 221 to rotate along the axis of the gear 216. Then, the flipping door 23 drives the drive assembly 21 and the main body 22 to rotate, thereby completing the retrieval and storage of the mechanical dog 1.
