Description

Technical Field

[0001] This invention relates to the field of intelligent robot technology, specifically to a steering device for an intelligent robot. Background Technology

[0002] A robot is an automated machine, but unlike humans, it possesses some intelligent capabilities similar to those of humans or other living beings, such as perception, planning, movement, and coordination. It is a highly flexible automated machine. Robots can assist or even replace humans in performing dangerous, arduous, and complex tasks, improving work efficiency and quality, serving human life, and expanding the scope of human activities and capabilities. With the rapid development of robotics technology, the demand for robots to replace humans in work is increasing.

[0003] Currently, existing robots are not convenient to turn, requiring them to make wide turns, which affects their turning efficiency. They also cannot turn smoothly when encountering dead angles. In addition, some robots use sharp turns to improve turning efficiency, which results in poor overall stability and a tendency to tip over, causing the robot to fall and break, affecting overall work efficiency, causing economic losses, and reducing its performance. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a steering device for intelligent robots. This device solves the problems of inconvenient steering in existing robots, which require large turns to turn, affecting steering efficiency. Furthermore, robots cannot turn smoothly when encountering dead angles. In order to improve steering efficiency, some robots use sharp turns, which result in poor overall stability and a tendency to tip over, causing the robot to fall and break, affecting overall work efficiency, causing economic losses, and reducing performance.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a steering device for an intelligent robot, comprising a body, a steering device, and a supporting device, wherein the steering device is located in the center of the body and near the bottom, and the supporting device is located in the body and near the steering device.

[0008] The supporting device includes a base plate, a bushing assembly, a top rod, an anti-slip device, a pressure plate, an arc-shaped spring, an elastic airbag, and a connecting hose. The base plate is fixed to the inner wall of the machine body near the bottom. The bushing assembly is disposed on the surface of the base plate near the edge. The top rod is slidably connected to the bushing assembly. The anti-slip device is disposed at the bottom end of the top rod. The pressure plate is fixed to the top end of the top rod. The arc-shaped spring is disposed between the top of the base plate and the corresponding sides of the bottom of the pressure plate. The elastic airbag is disposed between the top of the base plate and the corresponding sides of the bottom of the pressure plate, near the arc-shaped spring. The connecting hose is disposed between the elastic airbag and the anti-slip device. Between the two sides, when the telescopic mechanism extends, the working end of the telescopic mechanism pushes the pressure plate and the top rod to move downward together, so that the bottom of the anti-slip device is in contact with the contact surface, and the entire device is supported. At this time, the weight of the entire device is applied to the anti-slip device, and its own pressure makes the anti-slip device fit tightly with the contact surface, which helps to prevent slipping. At the same time, as the pressure plate presses the shaped spring and the elastic airbag, it is compressed. At this time, the gas inside the elastic airbag is delivered to the air chamber through the connecting hose, which further helps to prevent slipping, thereby improving the overall stability, fully connecting the structure together, realizing multiple functions, being safe and reliable, and improving the performance of use;

[0009] The anti-slip device includes a foot plate, a flexible horn-shaped component, and an expansion device. The top side of the foot plate is fixedly connected to the bottom end of the top rod. The flexible horn-shaped component is fixed to the bottom of the foot plate and near the edge. The expansion device is located at the bottom of the foot plate and in the center.

[0010] Preferably, a telescopic mechanism is fixedly connected to the bottom edge of the machine body near the corner. The working end of the telescopic mechanism is fixedly connected to the top of the pressure plate. A servo motor is installed inside the machine body. The output shaft of the servo motor is connected to the top of the steering device through a bevel gear set. When turning is required, the extension of the telescopic mechanism applies a pushing force to the supporting device, thereby supporting the entire device. The servo motor is used as the power source, and the steering device is driven by the bevel gear set to achieve rapid turning. The entire device can turn the robot quickly and smoothly without having to go around corners, making it less likely to tip over and break. It has good stability, extends the service life of the equipment, and improves work efficiency and performance.

[0011] Preferably, the top end of the connecting hose is connected to the air vent of the elastic airbag, the horn-shaped flexible parts are evenly distributed at the bottom edge of the foot plate, and the material of the horn-shaped flexible parts is rubber.

[0012] Preferably, the steering device includes a connecting shaft, a turntable, a drive wheel, and a steering wheel. The connecting shaft is rotatably connected to the inside of the machine body via a bracket. The center of the turntable surface is fixedly connected to the bottom of the connecting shaft surface. The drive wheel is located on one side of the bottom of the turntable, and the steering wheel is located on the bottom of the turntable away from the drive wheel. When the telescopic mechanism extends, the entire device is lifted. At this time, a servo motor is used as the power source, combined with a bevel gear set, to drive the steering device to rotate 180 degrees. The drive wheel and steering wheel adjust their positions, and the telescopic mechanism retracts to lower the device, thus completing the steering without the need for a roundabout turn, resulting in high steering efficiency and improved performance.

[0013] Preferably, the expansion device includes an air chamber, an expansion membrane, and an anti-slip layer. The air chamber is located at the center of the bottom of the foot plate and is connected to the bottom end of the connecting hose. The expansion membrane is located at the bottom of the foot plate and within the air chamber. The anti-slip layer is located at the bottom of the expansion membrane. Under pressure, the flexible horn-shaped component fits tightly against the contact surface. The flexible horn-shaped component is made of rubber, providing excellent anti-slip properties. Simultaneously, the connecting hose delivers compressed air from the elastic airbag into the air chamber. As the air pressure increases, the expansion membrane expands along with the anti-slip layer, causing the anti-slip layer to fit tightly against the contact surface again. This achieves multiple anti-slip effects, making the device more stable and less prone to slipping. This effectively reduces the risk of tipping over, ensuring safety and reliability, and improving performance.

[0014] Preferably, the bushing device includes a cylindrical body, a through hole, and a stabilizing device. The surface of the cylindrical body is fixedly connected to the surface of the base plate. The through hole is opened at the end of the cylindrical body. The push rod passes through the through hole. The stabilizing device is disposed on the inner wall of the cylindrical body.

[0015] Preferably, the stabilizing device includes an elastic pressure plate, a connector, a pressure head, and ball bearings. The end of the elastic pressure plate is fixedly connected to the inner wall of the cylinder. The connector is fixed at the center of the surface of the elastic pressure plate. One end of the pressure head is fixed to the surface of the elastic pressure plate near the connector. The ball bearings are rolled on the surface of the connector and the surface of the pressure head, away from the inner wall of the cylinder. When the push rod slides inside the bushing device, the evenly distributed stabilizing devices support the push rod together. Under the elastic force of the elastic pressure plate, the multiple support points of the connector and pressure head allow the push rod to slide smoothly, making it less susceptible to the influence of the fit clearance and less prone to shaking. It is more stable. At the same time, as the surface of the push rod contacts the ball bearings and uses rolling friction during sliding, the friction is reduced, making the sliding smooth. The interaction between the structures ensures safety and reliability and improves the performance.

[0016] Preferably, the balls are evenly distributed on the surface of the connector, the surface of the pressure head and the side away from the inner wall of the cylinder, and rolling grooves adapted to the balls are formed on the surface of the connector, the surface of the pressure head and the side away from the inner wall of the cylinder.

[0017] (III) Beneficial Effects

[0018] This invention provides a steering device for an intelligent robot. It has the following beneficial effects:

[0019] (I) The steering device of this intelligent robot, through the body, steering device, supporting device, telescopic mechanism, servo motor, and bevel gear set, when turning is required, utilizes the extension of the telescopic mechanism, the working end of which applies a pushing force to the supporting device, thereby supporting the entire device, and uses the servo motor as power, combined with the bevel gear set to drive the steering device, to achieve rapid turning. The entire device can turn the robot quickly and smoothly without the need for turning around, and is less prone to tipping over and falling. It has good stability, extends the service life of the equipment, and improves work efficiency and performance.

[0020] (II) The steering device of this intelligent robot, through a base plate, bushing device, push rod, anti-slip device, pressure plate, arc-shaped spring, elastic airbag, and connecting hose, when the telescopic mechanism extends, the working end of the telescopic mechanism pushes the pressure plate and push rod downward together, thereby causing the bottom of the anti-slip device to fit against the contact surface, and the entire device is supported. At this time, the weight of the entire device is applied to the anti-slip device, and its own pressure makes the anti-slip device fit tightly against the contact surface, which helps to prevent slipping. At the same time, as the pressure plate presses against the arc-shaped spring and elastic airbag, it is compressed. At this time, the internal gas of the elastic airbag is delivered to the air chamber through the connecting hose, which further helps to prevent slipping, thereby improving the overall stability, fully connecting the structure together, realizing multiple functions, being safe and reliable, and improving the performance of use.

[0021] (III) The steering device of this intelligent robot, through footplates, flexible horn-shaped parts, expansion device, air chamber, expansion membrane, and anti-slip layer, makes the flexible horn-shaped parts tightly fit with the contact surface under pressure. The flexible horn-shaped parts are made of rubber, which has a good anti-slip effect. At the same time, the gas inside the compressed elastic airbag is transported to the air chamber through the connecting hose. As the air pressure increases, the expansion membrane expands along with the anti-slip layer. At this time, the anti-slip layer tightly fits with the contact surface again, thus achieving a multi-layer anti-slip effect, making the whole more stable and less prone to slipping. It can effectively reduce the possibility of tipping over, making it safe, reliable, and improving its performance.

[0022] (iv) The steering device of this intelligent robot, through the cylinder, through hole, stabilizing device, elastic pressure plate, connector, pressure head, and ball bearings, allows the push rod to slide smoothly when it slides inside the bushing device. At this time, the evenly distributed stabilizing device supports the push rod together, and under the elastic force of the elastic pressure plate, the push rod slides smoothly using multiple support points such as the connector and pressure head. It is not easily affected by the fit clearance, and therefore is less prone to shaking, making it more stable. At the same time, as the surface of the push rod contacts the ball bearings, rolling friction is used during sliding, which reduces the friction force and makes the sliding smooth. By utilizing the interaction between the structures, it is safe and reliable, and improves the performance of use.

[0023] (V) The steering device of the intelligent robot is connected to a rotating shaft, a turntable, a drive wheel, and a steering wheel. When the telescopic mechanism extends, the entire device is lifted up. At this time, the servo motor is used as the power source, and the bevel gear set is combined to drive the steering device to rotate 180 degrees. At this time, the drive wheel and the steering wheel adjust their positions, and the telescopic mechanism retracts to lower the device, thereby completing the steering. There is no need to turn around, which makes the overall steering efficiency high and improves the performance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Implementation Case 1:

[0034] Please see Figure 1-7 The present invention provides a technical solution: a steering device for an intelligent robot, comprising a body 1, a steering device 2, and a supporting device 3. The steering device 2 is located in the center of the body 1 and near the bottom, and the supporting device 3 is located in the body 1 and near the steering device 2.

[0035] A telescopic mechanism 4 is fixedly connected to the bottom edge of the body 1 near the corner. The working end of the telescopic mechanism 4 is fixedly connected to the top of the pressure plate 35. A servo motor 5 is installed inside the body 1. The output shaft of the servo motor 5 is connected to the top of the steering device 2 through a bevel gear set 6. When turning is required, the extension of the telescopic mechanism 4 applies a pushing force to the supporting device 3, thereby supporting the entire device. The servo motor 5 is used as the power source, and the steering device 2 is driven by the bevel gear set 6 to achieve rapid turning. The entire device can turn the robot quickly and smoothly without having to turn around, making it less likely to tip over and break. It has good stability, extends the service life of the equipment, and improves work efficiency and performance.

[0036] Implementation Case 2:

[0037] The supporting device 3 includes a base plate 31, a bushing device 32, a push rod 33, an anti-slip device 34, a pressure plate 35, an arc-shaped spring 36, an elastic airbag 37, and a connecting hose 38. The base plate 31 is fixed to the inner wall of the body 1 near the bottom. The bushing device 32 is disposed on the surface of the base plate 31 near the edge. The push rod 33 is slidably connected to the bushing device 32. The anti-slip device 34 is disposed at the bottom end of the push rod 33. The pressure plate 35 is fixed to the top end of the push rod 33. The arc-shaped spring 36 is disposed between the top of the base plate 31 and the corresponding sides of the bottom of the pressure plate 35. The elastic airbag 37 is disposed between the top of the base plate 31 and the corresponding sides of the bottom of the pressure plate 35, near the arc-shaped spring 36. The connecting hose 38... The tube 38 is positioned between the elastic airbag 37 and the anti-slip device 34 on opposite sides. When the telescopic mechanism 4 extends, the working end of the telescopic mechanism 4 pushes the pressure plate 35 and the top rod 33 downward together, thereby causing the bottom of the anti-slip device 34 to fit against the contact surface, and the entire device is supported. At this time, the weight of the entire device is applied to the anti-slip device 34, and its own pressure makes the anti-slip device 34 fit tightly against the contact surface, which helps to prevent slipping. At the same time, as the pressure plate 35 presses against the shaped spring 36 and the elastic airbag 37, it is compressed. At this time, the gas inside the elastic airbag 37 is delivered to the air chamber 3431 through the connecting hose 38, which further helps to prevent slipping and improves the overall stability.

[0038] The anti-slip device 34 is provided with a foot plate 341, a flexible horn-shaped component 342, and an expansion device 343. The top side of the foot plate 341 is fixedly connected to the bottom end of the top rod 33. The flexible horn-shaped component 342 is fixed to the bottom of the foot plate 341 and close to the edge. The expansion device 343 is located at the bottom of the foot plate 341 and in the center.

[0039] The expansion device 343 includes an air chamber 3431, an expansion membrane 3432, and an anti-slip layer 3433. The air chamber 3431 is located at the center of the bottom of the foot plate 341 and is connected to the bottom end of the connecting hose 38. The expansion membrane 3432 is located at the bottom of the foot plate 341 and at the position of the air chamber 3431. The anti-slip layer 3433 is located at the bottom of the expansion membrane 3432. Under pressure, the flexible horn-shaped part 342 is tightly fitted to the contact surface. The flexible horn-shaped part 342 is made of rubber, which provides good anti-slip effect. At the same time, as the connecting hose 38 delivers the compressed air from the elastic airbag 37 into the air chamber 3431, the expansion membrane 3432 expands along with the anti-slip layer 3433 as the air pressure increases. At this time, the anti-slip layer 3433 is tightly fitted to the contact surface again, thus achieving multiple anti-slip effects, making the whole more stable and less prone to slipping, effectively reducing the possibility of tipping over.

[0040] Implementation Case 3:

[0041] The bushing device 32 is provided with a cylindrical body 321, a through hole 322, and a stabilizing device 323. The surface of the cylindrical body 321 is fixedly connected to the surface of the base plate 31. The through hole 322 is opened at the end of the cylindrical body 321. The push rod 33 passes through the through hole 322. The stabilizing device 323 is provided on the inner wall of the cylindrical body 321.

[0042] The stabilizing device 323 is provided with an elastic pressure plate 3231, a connector 3232, a pressure head 3233, and a ball bearing 3234. The end of the elastic pressure plate 3231 is fixedly connected to the inner wall of the cylinder 321. The connector 3232 is fixed at the center of the surface of the elastic pressure plate 3231. One end of the pressure head 3233 is fixed to the surface of the elastic pressure plate 3231 and close to the connector 3232. The ball bearing 3234 is rolled and connected to the surface of the connector 3232, the surface of the pressure head 3233, and the side away from the inner wall of the cylinder 321.

[0043] The balls 3234 are evenly distributed on the surface of the connector 3232 and the surface of the pressure head 3233, away from the inner wall of the cylinder 321. Rolling grooves adapted to the balls 3234 are opened on the surface of the connector 3232 and the surface of the pressure head 3233 away from the inner wall of the cylinder 321. When the push rod 33 slides inside the bushing device 32, the evenly distributed stabilizing device 323 supports the push rod 33 together. Under the elastic force of the elastic pressure plate 3231, the push rod 33 slides smoothly using multiple support points of the connector 3232 and the pressure head 3233. It is not easily affected by the fit clearance, and therefore is less likely to wobble, making it more stable. At the same time, as the surface of the push rod 33 contacts the balls 3234, rolling friction is used during sliding, reducing friction and making the sliding smooth.

[0044] Implementation Case 4:

[0045] The steering device 2 is equipped with a connecting shaft 21, a turntable 22, a drive wheel 23, and a steering wheel 24. The connecting shaft 21 is rotatably connected to the inside of the machine body 1 via a bracket. The center of the surface of the turntable 22 is fixedly connected to the bottom of the surface of the connecting shaft 21. The drive wheel 23 is located on one side of the bottom of the turntable 22, and the steering wheel 24 is located on the bottom of the turntable 22 away from the drive wheel 23. When the telescopic mechanism 4 extends, the entire device is lifted. At this time, the servo motor 5 is used as power, and in combination with the bevel gear set 6, the steering device 2 is rotated 180 degrees. At this time, the drive wheel 23 and the steering wheel 24 adjust their positions, and the telescopic mechanism 4 retracts to lower the device, thereby completing the steering without having to go around corners, making the overall steering efficiency high and improving the performance.

[0046] In use, when the telescopic mechanism 4 extends, its working end pushes the pressure plate 35 and the push rod 33 downwards, causing the bottom of the anti-slip device 34 to come into contact with the contact surface, thus supporting the entire device. At this time, the weight of the entire device is applied to the anti-slip device 34, using its own pressure to ensure a tight fit between the anti-slip device 34 and the contact surface, aiding in anti-slip. Simultaneously, as the pressure plate 35 presses against the shaped spring 36 and the elastic airbag 37, it is compressed. At this time, the gas inside the elastic airbag 37 is delivered through the connecting hose 38 to... Within the air chamber 3431, further anti-slip properties are enhanced, thereby improving overall stability. Under pressure, the flexible horn-shaped component 342 adheres tightly to the contact surface. The rubber material of the flexible horn-shaped component 342 provides excellent anti-slip performance. Simultaneously, the connecting hose 38 delivers gas from the compressed elastic airbag 37 into the air chamber 3431. As the air pressure increases, the expansion membrane 3432, along with the anti-slip layer 3433, expands. At this point, the anti-slip layer 3433 again adheres tightly to the contact surface, further enhancing stability. Multiple anti-slip effects are achieved, making the overall structure more stable and less prone to slippage, effectively reducing the risk of tipping over. When the top rod 33 slides inside the bushing device 32, the evenly distributed stabilizing devices 323 support the top rod 33. Under the elastic force of the elastic pressure plate 3231, the top rod 33 slides smoothly using multiple support points such as the connector 3232 and the pressure head 3233, making it less susceptible to the influence of the fit clearance and thus less prone to shaking, resulting in greater stability. At the same time, as the surface of the top rod 33 contacts the ball bearing 3234, rolling friction is used during sliding, reducing friction and making the sliding smooth. Furthermore, when the telescopic mechanism 4 extends, the entire device is lifted. At this time, the servo motor 5 is used as the power source, and in combination with the bevel gear set 6, the steering device 2 is rotated 180 degrees. At this time, the drive wheel 23 and the direction wheel 24 adjust their positions, and the telescopic mechanism 4 retracts to lower the device, thus completing the steering without the need for turning around, making the overall steering efficiency high and improving the performance.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
