A protective plate is fixedly installed on the surface of the inclined plate. A support column is slidably penetrated through the inner wall of the fixed base. A telescopic elastic rod II is fixedly installed at the top of the support column. A spring is provided between the protective plate and the fixed base. A rotating plate is rotatably installed at the bottom of the fixed base, and a universal wheel is rotatably installed at the bottom of the rotating plate, which improves the service experience of guests. At the same time, through the combination of "displaying expressions" visual interaction and "robotic arm movement" physical interaction, friendly service intentions are conveyed, enhancing the emotional experience of guests and avoiding the stiffness of pure mechanical actions, meeting the humanized needs of the welcome scenario.

[0007] The output end of the electric push rod is fixedly connected to the surface of the storage drawer, and the free end of the telescopic elastic rod I is fixedly connected to the protective plate.

[0009] The surface of the rotating plate is provided with an adaptable device for adapting to the slope of the road surface, and the adaptable device includes a fixed block, the fixed block is fixedly installed on the surface of the rotating plate, a connecting block is rotatably installed on the surface of the fixed block, a cleaning plate is fixedly installed on the end of the connecting block away from the fixed block, a telescopic elastic rod three is fixedly installed on the bottom of the fixed base, a motor is fixedly installed on the bottom of the fixed base, a brush plate is rotatably installed on the bottom of the motor, a rotating shaft is fixedly passed through the surface of the universal wheel, a collecting cylinder is fixedly installed on the circumferential surface of the rotating shaft, a turntable is fixedly installed on the circumferential surface of the rotating shaft, and a collecting box is fixedly installed on the bottom of the fixed base, so as to achieve the adaptability effect to different road conditions, so that the robot can still maintain the fit between the cleaning component and the ground when climbing slopes and crossing bumps, without affecting the cleaning effect, and will not collide with the cleaning plate when moving, thereby damaging the cleaning plate.

[0010] According to another aspect, at least one embodiment of the present disclosure further provides a welcoming robot, wherein the free end of the telescopic spring rod three is fixedly connected to a cleaning plate, and the surface of the cleaning plate is provided with bristles for cleaning and moving, thereby actively reducing the frequency of manual cleaning, reducing operating costs, and improving the cleanliness of the environment. At the same time, it avoids the spread of dust, improves the purity of the air, maintains a clean environment, and enhances guests' favorability towards the venue.

[0011] The shape of the collecting cylinder is set to be L-shaped, and a collecting groove is opened on the surface of the collecting box. A vacuum cleaner is arranged inside the collecting box to collect dust, which is then centrally processed by the staff to prevent it from falling or scattering during transportation and causing secondary pollution, thereby ensuring the integrity of the cleaning process.

[0012] For example, in a welcoming robot provided by at least one embodiment of the present disclosure, the circumferential surface of the support column is provided with an emergency avoidance device for limiting and jamming the universal wheel in an emergency situation, the emergency avoidance device includes a fixing ring, the fixing ring is fixedly mounted on the circumferential surface of the support column, a limiting plate is fixedly mounted on the surface of the fixing ring, a reciprocating screw is rotatably mounted on the surface of the universal wheel, a scraper is slidably mounted on the circumferential surface of the reciprocating screw, a rotating wheel is fixedly mounted on the circumferential surface of the reciprocating screw, an eccentric wheel is fixedly mounted on the circumferential surface of the reciprocating screw, a sliding frame is slidably mounted on the surface of the collecting box, and a knocking plate is fixedly mounted on the bottom of the sliding frame, thereby improving the dust handling efficiency of the collecting box, avoiding increased suction resistance of the vacuum cleaner or residual leakage due to dust compaction, improving the dust suction efficiency, and avoiding dust accumulation in dead corners inside the collection tank, which increases the difficulty of suction and collection.

[0013] The shape of the fixed ring is set to be L-shaped. The scraper is threadedly connected to the reciprocating lead screw. The scraper is slidably connected to the inner wall of the collection trough. Leak holes are provided on the surface of the scraper. The turntable contacts the runner. The surface of the knocking plate is set to be the first arc surface. The material of the limiting plate is rubber material, which can avoid affecting the operation efficiency of the collection cylinder, prevent functional failure caused by foreign object blockage, reduce the maintenance cost caused by mechanical failures, reduce the manual cleaning frequency, and reduce the risk of blockage or jamming of the bearings of the collection cylinder.

[0014] The beneficial effects of the embodiments of the present disclosure are as follows: In the present disclosure, communication is carried out with guests through the voice interaction module, and the doubts of guests are solved through voice and touch screen. At the same time, the display screen will swing the robotic arm by displaying expressions and transmitting signals, improving the service experience of guests. At the same time, the friendly service intention is conveyed through the combination of "displaying expressions" visual interaction and "robotic arm movement" physical interaction, enhancing the emotional experience of guests and avoiding the stiffness of pure mechanical actions, meeting the humanized needs of the welcome scene. When a guest requests something to drink, the display screen then transmits a signal to the electric push rod. The output end of the electric push rod moves towards the direction close to the touch screen and pushes the storage drawer to move. The movement of the storage drawer provides the mineral water stored inside it to the guest, further improving the service experience of the guest, ensuring that the supply is completed within a short time after the guest's request, reducing the waiting time, and thus improving the service convenience and user experience friendliness.

[0015] In the present disclosure, the movement of the protective plate drives the movement of the inclined plate. The inclined plate moves to contact and squeeze the support column to move downward. At this time, the support column moves downward under the action of the inclined plate until it touches the ground, avoiding the situation that the equipment topples under the action of external force or its own collision, improving the stability and reliability of the equipment during operation, avoiding the inclination, toppling of the fuselage or damage of internal components caused by external impact, reducing the maintenance cost, and the movement of the universal wheels will drive the rotation plate to rotate under the action of the road conditions to adapt to the road conditions, improving the adaptability and driving stability of the equipment.

[0016] In the present disclosure, the movement of the fixed block drives the rotation of the connecting block, and the rotation of the connecting block drives the cleaning plate to move upward, achieving the adaptation effect for different road conditions, enabling the robot to maintain the adhesion of the cleaning component to the ground when climbing slopes and crossing obstacles, without affecting the cleaning effect, and without colliding during movement to affect the cleaning plate and further damage the cleaning plate. The rotation of the output end of the motor drives the brush plate to rotate, and the rotation of the brush plate cleans and stirs the dust and foreign matters cleaned by the cleaning plate, actively reducing the frequency of manual cleaning, reducing the operation cost, improving the environmental cleanliness, simultaneously avoiding the spread of dust, improving the air purity, maintaining the environmental cleanliness, conveying the concept of "fine service", enhancing the trust and favor of guests towards the venue. The vacuum cleaner inside the collection box is started to suck away the dust or foreign matters accumulated inside the collection trough, realizing the collection of dust, and then it is centrally processed by the staff to prevent dropping or scattering during transportation and causing secondary pollution, ensuring the integrity of the cleaning process.

[0017] In the present disclosure, the reciprocating lead screw and the scraper are connected by threads. The rotation of the reciprocating lead screw drives the scraper to move, raising the dust inside the collection trough, thereby improving the processing efficiency of the collection box for dust, avoiding the increase in the suction resistance of the vacuum cleaner or residual suction caused by dust caking, enhancing the suction efficiency, avoiding the accumulation of dust in the dead corners inside the collection trough and increasing the difficulty of suction collection. The collection cylinder vibrates to shake off the dust or foreign matters attached or stuck on its surface through vibration, avoiding affecting the operation efficiency of the collection cylinder, preventing functional failure caused by foreign matter blockage, reducing the maintenance cost caused by mechanical failures, reducing the frequency of manual cleaning, and reducing the risk of blockage or jamming of the bearings of the collection cylinder.

[0018] In the present disclosure, the movement of the support column drives the movement of the limit plate until it contacts the surface of the universal wheel. Subsequently, the universal wheel is completely restricted from rotating under the action of the limit plate, further improving the emergency handling ability of the equipment in case of an accident, and immediately triggering braking to avoid the robot from tipping over or getting out of control, which can ensure the safety of surrounding people, especially children and the disabled, and form multiple-point stability with the support column, enabling the robot to still maintain balance when stressed unilaterally and avoiding equipment damage caused by the shift of the center of gravity.

[0027] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0028] Such as Figures 1 to 8As shown in the figure, it shows a welcome robot in an embodiment of the present disclosure, including a rotating base 1. A touch screen 2 is fixedly installed on the surface of the rotating base 1. A display screen 3 is fixedly installed on the top of the rotating base 1. A robotic arm 4 is rotatably installed on the surface of the rotating base 1. An anti-tipping device for preventing the robot from tipping over is provided at the bottom of the rotating base 1. The anti-tipping device includes a fixed base 51, and the fixed base 51 is fixedly installed at the bottom of the rotating base 1. A storage drawer 52 is slidably installed on the inner wall of the rotating base 1. An electric push rod 53 is fixedly installed on the inner wall of the rotating base 1. An inclined plate 54 is slidably installed on the inner wall of the fixed base 51. A telescopic elastic rod 55 is slidably installed on the surface of the fixed base 51. A protective plate 56 is fixedly installed on the surface of the inclined plate 54. A support column 57 is slidably penetrated through the inner wall of the fixed base 51. A telescopic elastic rod 58 is fixedly installed at the top of the support column 57. A spring 59 is provided between the protective plate 56 and the fixed base 51. A rotating plate 510 is rotatably installed at the bottom of the fixed base 51. A universal wheel 511 is rotatably installed at the bottom of the rotating plate 510. The movement of the universal wheel 511 will drive the rotating plate 510 to rotate under the action of the road conditions to adapt to the road conditions, improving the adaptability and driving stability of the device.

[0029] The output end of the electric push rod 53 is fixedly connected to the surface of the storage drawer 52. The free end of the telescopic elastic rod 55 is fixedly connected to the protective plate 56. An image sensing module and a transmission module are provided inside the display screen 3. The display screen 3 is electrically connected to the robotic arm 4. The display screen 3 is electrically connected to the electric push rod 53. The display screen 3 transmits a signal to the electric push rod 53, and the output end of the electric push rod 53 moves in the direction close to the touch screen 2 and pushes the storage drawer 52 to move.

[0030] In some examples, the free end of the telescopic elastic rod 58 is fixedly connected to the fixed base 51. One end of the inclined plate 54 close to the support column 57 is provided with an inclined surface 1 for squeezing the support column 57 to move downward. One end of the support column 57 close to the fixed base 51 is provided with an inclined surface 2 for assisting in force. The inclined plate 54 moves to contact and squeeze the support column 57 to move downward. At this time, the support column 57 moves downward under the action of the inclined plate 54 until it touches the ground. A lidar is provided inside the rotating base 1. A voice interaction module is provided inside the rotating base 1.

[0031] For example, as Figures 1 to 8As shown in the figure, when the device recognizes the visit of a guest through the display screen 3, it drives the universal wheel 511 to move in front of the guest, communicates with the guest through the voice interaction module, and solves the guest's doubts through voice and the touch screen 2. At the same time, the display screen 3 will convey a friendly service intention by combining "displaying expressions" visual interaction with "mechanical arm movement" physical interaction, enhancing the guest's emotional experience and avoiding the stiffness of pure mechanical actions, meeting the humanized needs of the welcome scenario. When the guest requests something to drink, the display screen 3 then sends a signal to the electric push rod 53. The output end of the electric push rod 53 moves towards the direction close to the touch screen 2 and pushes the storage drawer 52 to move. The movement of the storage drawer 52 provides the mineral water stored inside it to the guest, further enhancing the guest's service experience, ensuring the supply is completed within a short time after the guest's request, reducing the waiting time, and thus improving service convenience and user experience friendliness. When the device encounters a chassis collision during operation, the external force will squeeze the protective plate 56 to move towards the direction close to the support column 57. At the same time, the movement of the protective plate 56 drives the inclined plate 54 to move. The movement of the inclined plate 54 contacts and squeezes the support column 57 to move downward. At this time, the support column 57 moves downward under the action of the inclined plate 54 until it touches the ground, preventing the device from tipping over under the action of external force or its own collision, improving the stability and reliability of the device during operation, avoiding the body from tilting, tipping over or internal components being damaged due to external impact, and reducing the maintenance cost. When the device encounters complex road conditions, such as gentle slopes and carpets, the movement of the universal wheel 511 will drive the rotating plate 510 to rotate under the action of the road conditions to adapt to the road conditions, improving the adaptability and driving stability of the device.

[0032] As Figures 1 to 8 shown, it shows that in another embodiment of the present disclosure, an adaptation device for adapting to the road surface slope is provided on the surface of the rotating plate 510. The adaptation device includes a fixed block 61, the fixed block 61 is fixedly installed on the surface of the rotating plate 510, a connecting block 62 is rotatably installed on the surface of the fixed block 61, a cleaning plate 63 is fixedly installed at one end of the connecting block 62 away from the fixed block 61, a telescopic spring rod three 64 is fixedly installed at the bottom of the fixed base 51, a motor 65 is fixedly installed at the bottom of the fixed base 51, a brush plate 66 is rotatably installed at the bottom of the motor 65, a rotating shaft 67 is fixedly penetrated through the surface of the universal wheel 511, a collection cylinder 68 is fixedly installed on the circumferential surface of the rotating shaft 67, a turntable 69 is fixedly installed on the circumferential surface of the rotating shaft 67, a collection box 610 is fixedly installed at the bottom of the fixed base 51, and the vacuum cleaner inside the collection box 610 is started to suck away the dust or foreign objects accumulated in the collection groove.

[0033] The free end of the telescopic spring rod three 64 is fixedly connected to the cleaning plate 63, and bristles are provided on the surface of the cleaning plate 63. The movement of the device drives the cleaning plate 63 to clean the ground.

[0034] The shape of the collection cylinder 68 is set to an L shape. The movement trajectory of dust and foreign objects being swept into the collection cylinder 68 by the brush plate 66. The surface of the collection box 610 is provided with a collection groove, and a dust collector is arranged inside the collection box 610. In some examples, an emergency avoidance device for limiting and locking the universal wheel 511 in case of emergency is provided on the circumferential surface of the support column 57. The emergency avoidance device includes a fixed ring 71 fixedly installed on the circumferential surface of the support column 57. A limiting plate 72 is fixedly installed on the surface of the fixed ring 71. A reciprocating lead screw 73 is rotatably installed on the surface of the universal wheel 511. A scraping plate 74 is slidably installed on the circumferential surface of the reciprocating lead screw 73. A runner 75 is fixedly installed on the circumferential surface of the reciprocating lead screw 73. An eccentric wheel 76 is fixed on the circumferential surface of the reciprocating lead screw 73. A sliding frame 77 is slidably installed on the surface of the collection box 610. A knocking plate 78 is fixedly installed at the bottom of the sliding frame 77. The knocking plate 78 moves downward under the action of the sliding frame 77 to contact and collide with the surface of the collection cylinder 68 to generate vibration.

[0035] The shape of the fixed ring 71 is set to an L shape. The scraping plate 74 is threadedly connected to the reciprocating lead screw 73. The scraping plate 74 is slidably connected to the inner wall of the collection groove. Leak holes are provided on the surface of the scraping plate 74. The turntable 69 contacts the runner 75. The surface of the knocking plate 78 is set to a first arc surface. The material of the limiting plate 72 is rubber. The movement of the support column 57 drives the limiting plate 72 to move until it contacts the surface of the universal wheel 511. Subsequently, the rotation of the universal wheel 511 is completely restricted under the action of the limiting plate 72.

[0036] For example, such as Figures 1 to 8As shown, when the rotating plate 510 rotates under the action of the universal wheel 511, it drives the fixed block 61 to move, and at the same time, the movement of the fixed block 61 drives the connecting block 62 to rotate, and the rotation of the connecting block 62 drives the cleaning plate 63 to move upward, so as to achieve the adaptability to different road conditions, so that the robot can still maintain the fit between the cleaning parts and the ground when climbing a slope or crossing a ridge, without affecting the cleaning effect, and will not collide with the cleaning plate 63 during movement, thereby damaging the cleaning plate 63. At the same time, the movement of the equipment drives the cleaning plate 63 to clean the ground, and the motor 65 is started during driving, and the output end of the motor 65 rotates to drive the brush plate 66 to rotate, and the brush plate 66 rotates to clean the dust and foreign matter cleaned by the cleaning plate 63, thereby actively reducing the frequency of manual cleaning. Secondly, it reduces operating costs, improves environmental cleanliness, avoids dust diffusion, improves air purity, maintains a clean environment, and enhances guests' favorability towards the venue. Subsequently, dust and foreign matter are pushed into the movement trajectory of the collection tube 68 under the action of the brush plate 66. The universal wheel 511 moves and rotates under the action of the ground, driving the rotating shaft 67 to rotate. The rotation of the rotating shaft 67 drives the collection tube 68 to rotate. At the same time, the collection tube 68 rotates to transport dust and foreign matter into the collection tank. At this time, the vacuum cleaner inside the collection box 610 is started to suck away the dust or foreign matter accumulated in the collection tank, thereby realizing the collection of dust. The dust is then centrally processed by the staff to prevent it from falling or scattering during transportation, causing secondary pollution, and ensuring the integrity of the cleaning process.

[0037] Due to the contact between the runner 75 and the turntable 69, the turntable 69 rotates under the action of the rotating shaft 67, driving the runner 75 to rotate. The rotation of the runner 75 drives the reciprocating lead screw 73 to rotate. Since the reciprocating lead screw 73 is threadedly connected to the scraper 74, the rotation of the reciprocating lead screw 73 drives the scraper 74 to move, raising the dust inside the collection tank, thereby improving the processing efficiency of the dust by the collection box 610, avoiding an increase in the suction resistance of the vacuum cleaner or residual suction caused by dust caking, enhancing the suction efficiency, preventing the dust inside the collection tank from accumulating in dead corners and increasing the difficulty of suction collection. At the same time, the movement of the reciprocating lead screw 73 drives the eccentric wheel 76 to rotate. At the same time, the rotation of the eccentric wheel 76 contacts and presses the sliding frame 77 to move downward. The downward movement of the sliding frame 77 drives the striking plate 78 to move. At this time, the striking plate 78 moves downward under the action of the sliding frame 77, contacts and collides with the surface of the collection cylinder 68 to generate vibration. The vibration of the collection cylinder 68 shakes off the dust or foreign objects attached or stuck to its surface, avoiding affecting the operating efficiency of the collection cylinder 68, preventing functional failure caused by foreign object blockage, reducing the maintenance cost caused by mechanical failures, reducing the manual cleaning frequency, and reducing the risk of blockage or jamming of the bearings of the collection cylinder 68. At the same time, the support column 57 moves downward under the action of the inclined plate 54. The movement of the support column 57 drives the limit plate 72 to move until it contacts the surface of the universal wheel 511. Subsequently, the universal wheel 511 is completely restricted from rotating under the action of the limit plate 72, further improving the emergency handling ability of the device in case of an accident, and immediately triggering braking, avoiding the robot from tipping over or getting out of control, ensuring the safety of surrounding people, especially children and the disabled, and forming a multi-point stability with the support column 57, enabling the robot to remain balanced even when subjected to unilateral force and avoiding equipment damage caused by center of gravity shift.
