Description

Technical Field

[0001] This utility model relates to the field of stair-climbing vehicle technology, specifically a new type of fully automatic procurement vehicle for overcoming obstacles and climbing stairs. Background Art

[0002] In modern society, with the continuous development of technology and changes in population structure, especially the aging population and the increase in high-rise buildings in cities, traditional methods of purchasing goods face numerous challenges. With technological advancements, robots are increasingly permeating our daily lives. Particularly during the pandemic, the surge in demand for contactless services spurred the rapid development of robots that climb stairs to purchase daily necessities. These robots are primarily used to assist people in buying everyday items, especially in older residential areas or buildings without elevators.

[0003] The following problems were found in the relevant technologies: most material procurement robots are only suitable for handling large materials. For small materials, such as daily necessities, they do not meet the robot specifications, resulting in a waste of resources. Material procurement robots do not have the ability to grasp goods and cannot achieve fully automated procurement of goods.

[0004] During the climbing process, the horizontal position of the stair-climbing cargo-carrying mechanism is difficult to maintain, and the inclination angle of the steps usually changes accordingly. This situation may reduce the stability of the cargo, thereby affecting transportation efficiency and safety;

[0005] The wear and tear on the edges of staircases caused by tracked stair-climbing mechanisms during prolonged operation should not be underestimated. This physical contact can gradually erode the staircase edges, affecting not only the integrity of the building structure but also posing a potential safety hazard and increasing the risk of injury.

[0006] In response, we have proposed a new type of fully automated procurement vehicle capable of overcoming obstacles and climbing stairs.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Summary of the Invention

[0008] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of automatic stair-climbing procurement in the prior art, this utility model provides a novel fully automatic stair-climbing procurement cart that combines a fully automatic grasping structure with a stair-climbing structure to achieve convenient procurement and user-friendly operation. Its specific technical solution is as follows:

[0009] A novel fully automated sourcing vehicle for overcoming obstacles and climbing stairs includes an obstacle-crossing and stair-climbing vehicle. The vehicle is equipped with a sourcing box, and above the sourcing box is a lifting component fixed to the vehicle. A base frame is rotatably mounted on the lifting end of the lifting component, and a support shaft is rotatably mounted on the base frame. A crank is sleeved on the outer wall of the support shaft, and a support arm is rotatably connected to the support shaft. An adapter seat is rotatably mounted on the free end of the support arm, and an arc-shaped arm is rotatably connected between the adapter seat and the crank. A gripping component is rotatably mounted on the side of the adapter seat away from the arc-shaped arm.

[0010] In the above technical solution, the gripping component includes a bracket rotatably mounted on the adapter seat, a guide rail is provided on the side wall of the bracket, a slide is slidably mounted on the guide rail, a gripper is provided on the side wall of the slide, and a retracting component is provided on the bracket to drive the gripper to grip the goods.

[0011] The tensioning component includes a rotating frame rotatably mounted at the bottom of the support, with one end of a connecting rod rotatably connected to both ends of the rotating frame, and the other end of the connecting rod rotatably connected to the slide.

[0012] The purchasing box is slidably mounted on the obstacle-crossing and stair-climbing vehicle, and the obstacle-crossing and stair-climbing vehicle is equipped with a displacement component for adjusting the position of the purchasing box.

[0013] The displacement component includes a lead screw rotatably mounted on the obstacle-crossing and stair-climbing vehicle, and a movable seat is threadedly connected to the outer wall of the lead screw. The movable seat is fixedly connected to the purchasing box.

[0014] The adapter is equipped with a camera for identifying goods.

[0015] The lifting component includes a support platform fixedly installed on the obstacle-crossing and stair-climbing vehicle, and the support platform is located above the purchasing box. The base frame is rotatably mounted on the top of the lifting platform. A scissor frame is provided between the lifting platform and the support platform, and a driving component is provided on the support platform to drive the scissor frame to extend and retract.

[0016] The driving component includes a telescopic member rotatably mounted on the top of the support platform, and the movable end of the telescopic member is rotatably mounted on the outer wall of one of the support rods of the scissor frame.

[0017] The obstacle-crossing and stair-climbing vehicle is equipped with a tilt sensor, which is electrically connected to the obstacle-crossing adjustment component on the vehicle.

[0018] The obstacle-crossing adjustment assembly includes a drive unit disposed at the bottom of the obstacle-crossing stair-climbing vehicle, an obstacle-crossing component disposed at the output end of the drive unit, and an obstacle-crossing wheel disposed at the free end of the obstacle-crossing component.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This new fully automatic procurement trolley for overcoming obstacles and climbing stairs:

[0020] First, by adjusting the height of the base frame through the lifting component, sufficient gripping space is ensured during the goods retrieval and procurement process. The base frame rotates on top of the lifting component, thereby circumferentially adjusting the direction of the procured and distributed goods and ensuring the accuracy of the goods procurement and distribution position.

[0021] Second, the identification signal is sequentially transmitted to each servo motor on the obstacle-crossing and stair-climbing vehicle through the identification camera and positioning sensor on the adapter. The support shaft drives the support arm and crank to rotate simultaneously. As the support arm rotates, the curvature of the gripping component is adjusted. At the same time, the crank, through the bow-shaped arm, causes the adapter to drive the gripping component to rotate, increasing the range of motion of the gripping component. This provides a wider space for picking up goods during procurement, thereby ensuring the efficiency of the procurement process and meeting the needs of residents.

[0022] Third, the application of fully automated daily necessities purchasing carts not only greatly facilitates residents' lives, but also reduces the frequency of delivery vehicle use, which helps to reduce traffic congestion and environmental pollution.

[0023] Fourth, after the camera identifies the goods, it transmits the signal to the retracting component, which drives the two slides to slide relative to each other on the guide rail. The two slides then drive the two grippers to grab the goods. The distance between the two grippers can be adjusted according to the specifications of the goods, thus making it suitable for purchasing goods of different specifications.

[0024] 5. When grabbing goods, the output shaft of the servo motor drives the rotating frame to rotate, which in turn drives one end of the connecting rod that is hinged at both ends to rotate. This causes the other end of the connecting rod to move the hinged slide. Through the guiding action of the guide rail and the slide, the two slides drive the two grippers to move relative to each other, thereby grabbing the goods. Then, by adjusting the angle, the goods are grabbed into the inside of the purchasing box.

[0025] 6. When purchasing and retrieving goods, the position of the purchasing box can be adjusted by the displacement component, so that the goods in the purchasing box can be taken out during the purchase and distribution process, avoiding the impact of limited retrieval space on the distribution of goods.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The following are specific implementation cases and appendices. Figure 1-6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0035] A novel fully automated obstacle-crossing and stair-climbing purchasing trolley includes an obstacle-crossing and stair-climbing vehicle 1, on which a purchasing box 3 is mounted. A base 2 is fixedly embedded in the obstacle-crossing and stair-climbing vehicle 1, with the base 2 positioned relatively parallel to the driving surface of the obstacle-crossing and stair-climbing vehicle 1. The purchasing box 3 slides against the top of the base 2. Above the purchasing box 3, a lifting component is fixed to the obstacle-crossing and stair-climbing vehicle 1. A base frame 5 is rotatably mounted on the lifting end of the lifting component, and a support shaft 6 is rotatably mounted on the base frame 5. A support arm 8 is sleeved on the outer wall of the support shaft 6. By adjusting the height of the base frame 5 through the lifting component, sufficient gripping space is ensured during the goods retrieval and purchasing process.

[0036] The base frame 5 rotates on top of the supporting component, thereby circumferentially adjusting the direction of the purchased and distributed goods and ensuring the accuracy of the goods' placement. Bearings are embedded in the inner walls on both sides of the top of the base frame 5, and the two ends of the support shaft 6 are respectively embedded in the two bearings, allowing the support shaft 6 to rotate on the base frame 5. Cranks 7 are fixedly sleeved on the outside of the support shaft 6 through mounting holes at one end, allowing the cranks 7 to rotate with the support shaft 6. A servo motor is fixedly mounted on the outer wall of the base frame 5, and the output shaft of the servo motor is fixedly connected to one end of the support shaft 6. The servo motor is electrically connected to an external power source via wires.

[0037] A connecting seat 10 is rotatably mounted on the free end of the support arm 8, and an arc-shaped arm 9 is rotatably connected between the connecting seat 10 and the crank 7. A gripping component is rotatably mounted on the side of the connecting seat 10 away from the arc-shaped arm 9. The lower end of the support arm 8 is movably sleeved on the outside of the support shaft 6 through an opening in the mounting hole. The upper end of the support arm 8 has a shaft body rotatably mounted on its inner cavity through a bearing. The connecting seat 10 is fixedly sleeved on the outside of the shaft body through an opening in the mounting hole of the connector, so that both ends of the support arm 8 are hinged to the connecting seat 10 and the support shaft 6, respectively. That is, the crank 7 rotates with the support shaft 6, and the support arm 8 is movably sleeved on the outside of the support shaft 6. The other end of the crank 7 is hinged to one end of the arc-shaped arm 9, and the other end of the arc-shaped arm 9 is hinged to the connecting seat 10. A servo motor is embedded and mounted on the surface of the connecting seat 10 away from the arc-shaped arm 9. The servo motor is electrically connected to an external power source through a wire, so that the gripping component rotates with the output shaft of the servo motor.

[0038] During the procurement and distribution of goods, the identification signal from the recognition camera and positioning sensor on the adapter 10 is sequentially transmitted to the various servo motors on the obstacle-crossing and stair-climbing vehicle 1. Based on the identified goods, the height of the gripping component is adjusted by the lifting mechanism, the gripping angle is adjusted circumferentially by the base frame 5, and then the support shaft 6 simultaneously drives the support arm 8 and crank 7 to rotate. As the support arm 8 rotates, the curvature of the gripping component is adjusted, while the crank 7, through the bow-shaped arm 9, causes the adapter 10 to rotate the gripping component, increasing the range of motion of the gripping component and providing a wider retrieval space during goods procurement, thus ensuring the efficiency of the procurement process and meeting the needs of residents.

[0039] The application of fully automated daily necessities purchasing carts has not only greatly facilitated residents' lives, but also reduced the frequency of delivery vehicle use, helping to reduce traffic congestion and environmental pollution.

[0040] The gripping assembly includes a bracket 11 rotatably mounted on an adapter 10. The bracket 11 is fixedly sleeved onto the outside of a servo motor output shaft on the adapter 10 via a mounting hole, and the servo motor output shaft drives the bracket 11 to rotate. A guide rail 12 is provided on the side wall of the bracket 11. The guide rail 12 is fixedly mounted on the surface of the bracket 11 away from the adapter 10. Two slide blocks 13 slide on the guide rail 12, with the slide blocks 13 slidably mounted opposite each other on the guide rail 12. A gripper 14 is provided on the side wall of the slide block 13, and a retraction / expansion component is provided on the bracket 11 to drive the gripper 14 to grip the goods.

[0041] The retracting component drives two slide blocks 13 to move relative to each other or back to back. After the recognition camera identifies the goods, it transmits the signal to the retracting component, causing the retracting component to drive the two slide blocks 13 to slide relative to each other on the guide rail 12. The two relative slide blocks 13 drive two grippers 14 to grab the goods. The distance between the two grippers 14 can be adjusted according to the specifications of the goods, so that it can be used for the procurement of goods of different specifications.

[0042] It is worth noting that the tensioning component includes a rotating frame 15 rotatably mounted at the bottom of the bracket 11. Both ends of the rotating frame 15 are rotatably connected to one end of a connecting rod 16, and the other end of the connecting rod 16 is rotatably connected to a slide block 13. A servo motor is fixed at the bottom of the bracket 11. The servo motor is electrically connected to an external power source via a wire. The output shaft of the servo motor is located below the bracket 11 and is in a position perpendicular to the bottom of the bracket 11.

[0043] The rotating frame 15 is fixedly sleeved to the outside of the servo output shaft through a mounting hole at its center. Shafts are vertically fixed at both ends of the rotating frame 15. One end of each of the two connecting rods 16 is movably sleeved to the outside of the shaft through a mounting hole. Shafts are vertically mounted at the bottom of each of the two slides 13. The other end of each of the two connecting rods 16 is movably sleeved to the outside of the shaft through a mounting hole, so that both ends of the connecting rods 16 are hinged to the bracket 11 and the slide 13, respectively.

[0044] When grabbing goods, the output shaft of the servo motor drives the rotating frame 15 to rotate, which in turn drives one end of the connecting rod 16 with hinged ends to rotate. This causes the other end of the connecting rod 16 to move the hinged slide 13. Through the guiding effect of the guide rail 12 and the slide 13, the two slides 13 drive the two grippers 14 to move relative to each other, thereby grabbing the goods. Then, by adjusting the angle, the goods are grabbed into the inside of the purchasing box 3.

[0045] The purchasing box 3 is slidably mounted on the obstacle-crossing stair-climbing vehicle 1, and the obstacle-crossing stair-climbing vehicle 1 is equipped with a displacement component for adjusting the position of the purchasing box 3. The position of the purchasing box 3 on the obstacle-crossing stair-climbing vehicle 1 is adjusted by the displacement component.

[0046] When purchasing and retrieving goods, the position of the purchasing box 3 is adjusted by the displacement component, so that the goods can be taken out of the purchasing box 3 during the purchasing and distribution process, avoiding the restriction of retrieval space from affecting the distribution of goods.

[0047] Furthermore, the displacement assembly includes a lead screw 24 rotatably mounted on the obstacle-crossing and stair-climbing vehicle 1. A movable seat 26 is threadedly connected to the outer wall of the lead screw 24, and the movable seat 26 is fixedly connected to the purchasing box 3. A through groove 27 is formed on the surface of the base 2 at a position corresponding to the purchasing box 3. Fixed seats 28 are vertically fixedly installed at the bottom of the base 2 at both ends of the through groove. Bearings are embedded in the opposing surfaces of the two fixed seats 28, and the two ends of the lead screw 24 are respectively embedded inside the two bearings. The movable seat 26 is connected to the lead screw 24 through a threaded hole penetrating the inner cavity.

[0048] A stabilizing rod 25, parallel to the lead screw 24, is fixedly installed between two fixed seats 28. A movable seat 26 slides movably on the outer wall of the stabilizing rod 25. A fixed rod 29 connects the top of the movable seat 26 to the bottom of the purchasing box 3. The fixed rod 29 passes through the inner cavity of the through groove 27. A motor is fixed to the surface of one of the fixed seats 28 by a cover, and the output shaft of the motor passes through the fixed seat and is fixedly connected to one end of the lead screw 24.

[0049] When adjusting the position of the purchasing box 3, the output shaft of the motor drives the lead screw 24 to rotate, which causes the movable seat 26, which is threadedly connected to the lead screw 24, to move the purchasing box 3 through the fixed rod 29 in the through slot 27, thereby adjusting the position of the purchasing box 3. The position of the purchasing box 3 is adjusted according to the position of the gripper 14, ensuring the accuracy of the purchasing goods picking and placing process.

[0050] The adapter 10 is equipped with a camera for identifying goods. Through image recognition and sensing elements, the camera can accurately locate and grab the required goods.

[0051] Additionally, the lifting component includes a support platform 17 fixedly mounted on the obstacle-crossing and stair-climbing vehicle 1, with the support platform 17 positioned above the procurement box 3. A base frame 5 is rotatably mounted on top of the lifting platform 4. The base frame 5 is fixedly mounted on top of the rotating seat, and a servo motor is embedded in the top of the lifting platform 4. The rotating seat is fixedly fitted onto the outside of the servo motor's output shaft through a centrally located mounting hole. The servo motor is electrically connected to an external power source via wires. A scissor frame 18 is provided between the lifting platform 4 and the support platform 17, and a drive component is provided on the support platform 17 to retract and extend the scissor frame 18.

[0052] The scissor frame 18 is composed of two support rods hinged together. All four ends of the scissor frame 18 are rotatably connected to sliding seats, which are slidably mounted on the opposite surfaces of the lifting platform 4 and the support base 17 via sliding rods. A driving mechanism allows the scissor frame 18 to fold or unfold, thereby adjusting the height of the lifting platform 4.

[0053] The driving component includes a telescopic member 19 rotatably mounted on the top of the support platform 17. The movable end of the telescopic member 19 is rotatably mounted on the outer wall of a support rod of the scissor frame 18. The telescopic member 19 can be an electrically operated telescopic rod. The outer cylindrical end of the telescopic member 19 is movably sleeved on the outside of the shaft on the support platform 17 through a mounting hole in the connector. The movable end of the telescopic member 19 is movably sleeved on the outside of the shaft on a support rod of the scissor frame 18 through a mounting hole in the connector. By pushing the support rod of the scissor frame 18 with the movable end of the telescopic member 19, the scissor frame 18 is folded or unfolded, thereby adjusting the height position of the gripper 14.

[0054] Furthermore, the obstacle-crossing stair-climbing vehicle 1 is equipped with a tilt sensor 21, which is electrically connected to the obstacle-crossing adjustment component on the vehicle 1. The tilt sensor 21 transmits signals to the obstacle-crossing component 23 in a timely manner, allowing the obstacle-crossing stair-climbing vehicle 1 to adjust its balance promptly, thus ensuring stability during movement.

[0055] The obstacle-crossing adjustment assembly includes a drive unit 20 located at the bottom of the obstacle-crossing stair-climbing vehicle 1. An obstacle-crossing component 23 is located at the output end of the drive unit 20, and an obstacle-crossing wheel 22 is located at the free end of the obstacle-crossing component 23. The drive unit 20 drives the obstacle-crossing component 23, which in turn moves the obstacle-crossing wheel 22, allowing the obstacle-crossing wheel 22 to gradually move along the route on the performance venue.

[0056] The obstacle-crossing stair-climbing vehicle 1 features an adaptive height adjustment function. The transmission system for this function employs a motor coupled with a two-stage gear transmission. This adaptive height adjustment function changes the height of the vehicle's center of gravity relative to the contact point, thereby enabling its vertical movement. The drive unit 20 on the obstacle-crossing stair-climbing vehicle 1 includes crank-rocker components. The dual-wheel drive half-turn lifting design on the crank-rocker effectively reduces the complexity of the stair-climbing mechanism by minimizing the lifting angle to half a turn, thus improving the stability and reliability of the obstacle-crossing stair-climbing vehicle 1. This design makes the crank-rocker movement in stairwells more flexible and stable, enabling the obstacle-crossing stair-climbing vehicle 1 to achieve efficient operation in various environments.

[0057] Key components of the crank-rocker include: a one-way wheel, which provides support when traveling on flat ground and automatically lifts when encountering stairs, exploring and locking onto the edge of the stairs as a support point; a transmission mechanism, which connects the motor and other components, transmitting the motor's power to the entire system to drive the obstacle-crossing stair-climbing vehicle 1 to climb stairs; a crank assembly, which works with the toggle wheel to realize the mechanism's alternating forward and backward lifting strategy, helping the mechanism move flexibly in stairwells; and the toggle wheel, which works in conjunction with the crank assembly to lift the front end of the mechanism upward, while working with the height adjustment mechanism to ensure that the rear end of the obstacle-crossing stair-climbing vehicle 1 is stably stopped on the next step of the stairs.

[0058] This embodiment describes a novel fully automatic purchasing cart that can overcome obstacles and climb stairs. The working principle is as follows: the driving component 20 drives the obstacle-crossing component 23 to move the obstacle-crossing wheel 22, so that the obstacle-crossing wheel 22 drives the purchasing box 3 to purchase items.

[0059] When the desired item is detected, the movable end of the telescopic component 19 pushes a support rod of the scissor frame 18 to move, causing the scissor frame 18 to fold or unfold, adjusting the height position of the gripper 14.

[0060] Then, the servo motor drives the support shaft 6 to rotate, which in turn drives the support arm 8 and the crank 7 to rotate. As the support arm 8 rotates, the curvature of the gripper 14 is adjusted. At the same time, the crank 7 drives the adapter 10 to rotate the gripper 14 through the bow-shaped arm 9.

[0061] Then, the output shaft of the servo motor drives the rotating frame 15 to rotate, which in turn drives one end of the connecting rod 16, which is hinged at both ends, to rotate. This causes the other end of the connecting rod 16 to move the hinged slide 13. Through the guiding action of the guide rail 12 and the slide 13, the two slides 13 respectively drive the two grippers 14 to move relative to each other. At the same time, the position of the purchasing box 3 is adjusted to grab the goods into the purchasing box 3.
