The top surface of the rod groove 1 3311 is open, and the width of the opening of the top surface of the rod groove 1 3311 is The rod groove 1 3311 is connected to the rod groove 2 3312, the width of the top opening of the rod groove 2 3312 is larger than the diameter of the support rod 336, the push cylinder 332 is arranged at the end of the rod groove 1 3311 away from the rod groove 2 3312, the length direction of the rod groove 1 3311, the length direction of the rod groove 2 3312, the length direction of the insertion rod 333 and the extension direction of the piston rod of the push cylinder 332 are all the same; the auxiliary wheel 34 is provided with a wheel frame 341 on the outside The auxiliary wheel 34 is rotatably arranged on the bottom surface of the wheel frame 341, the end of the connecting rod 335 away from the storage groove 311 is hinged to the wheel frame 341, the end of the rod sleeve 334 away from the rod 333 is in conflict with the wheel frame 341, and an arc-shaped spring plate 342 is arranged on the side wall of the wheel frame 341 away from the chassis 32 with wheels, the arc-shaped opening of the arc-shaped spring plate 342 faces the wheel frame 341, and a plurality of buffer springs 343 connected to the wheel frame 341 are arranged in the arc-shaped opening of the arc-shaped spring plate 342.

[0029] When the present wheeled robot based on consumer complaints and services is traveling on an environment with a low-lying road surface, the push cylinder 332 is first started to drive the insertion rod 333 to retract, so that the insertion rod 333 and the insertion rod sleeve 334 are separated; the auxiliary wheel 34 can first fall onto the low-lying road surface (the connecting rod 335 and the top surface hinged end in the opening of the storage groove 311 can be rotatably connected by a rotating shaft with a torsion spring, so that when the present wheeled robot based on consumer complaints and services is traveling on a flat road surface, under the action of the gravity of the wheeled robot based on consumer complaints and services, the auxiliary wheel 34 can be in contact with the ground to ensure the normal driving of the wheeled robot based on consumer complaints and services; and when there is a low-lying road When the vehicle is on the flat surface, the wheel frame 341 can be rotated toward the low-lying road surface under the action of the rotating shaft with a torsion spring, and then can contact the low-lying road surface. At this time, the chassis 32 with wheels is still on the flat road surface, thereby preventing the chassis 32 with wheels from falling directly onto the low-lying road surface, causing the overall tilt of the wheeled robot based on consumer complaints and services); at this time, the two ends of the connecting rod 335 in the length direction respectively rotate on the top surface in the opening of the storage groove 311 and the auxiliary wheel 34, so that the wheel frame 341 falls onto the low-lying road surface, thereby stabilizing the main body of the service robot, avoiding or preventing the wheeled robot based on consumer complaints and services from falling due to tilting during driving.

[0030] When the wheeled robot based on consumer complaints and services is traveling on a flat road, the pushing cylinder 332 is first started to push the insertion rod 333, so that the end of the insertion rod 333 away from the pushing cylinder 332 passes through the rod groove 1 3311 and the rod groove 2 3312 and is inserted into the insertion rod sleeve 334, which can prevent the wheel frame 341 and the chassis 32 with wheels from shaking up and down, thereby facilitating the stable driving of the wheeled robot based on consumer complaints and services on flat ground.

[0031] The arrangement of the rod groove 1 3311 and the rod groove 2 3312 also allows the connecting end of the connecting rod 335 and the storage groove 311 to be removed when the wheel frame 341 (auxiliary wheel 34) is not in use, and the pushing cylinder 332 is started to drive the insertion rod 333 to retract into the rod groove 1 3311; then the wheel frame 341 is moved toward the direction of the chassis 32 with wheels, so that the insertion rod sleeve 334 can be inserted into the rod groove 2 3312, and then the insertion rod sleeve 334 is fixedly connected to the rod groove 2 3312 (bolts can be used to pass through the rod groove 2 3312 to the outer peripheral wall of the insertion rod sleeve 334); or when the wheel frame 341 (auxiliary wheel 34) is not in use, the connecting end of the connecting rod 335 and the storage groove 311 can be removed.

[0032] The arc-shaped spring plate 342 can play a certain buffering role and protect the auxiliary wheel 34 when the wheel frame 341 falls on the low-lying road surface first.

[0033] Embodiment 3 Based on the first embodiment, Figures 2 to 3 , Figures 7 and 8 As shown, a shielding roller curtain assembly 5 is also arranged in the robot housing 1, and the shielding roller curtain assembly 5 is located between the recording slot 44 and the microphone 42.

[0034] When the wheeled robot based on consumer complaints and services is in normal working state and the microphone 42 needs to be used, the drive motor 51 can be started to drive the half-toothed gear 52 to rotate (the start switch of the drive motor 51 can be set on the outer wall of the robot shell 1, and the switch can be pressed to start the drive motor 51 before using the wheeled robot based on consumer complaints and services). When the half-toothed gear 52 is engaged with the driven gear 53, the driven gear 53 is driven to rotate, thereby driving the reel 54 to rotate, so that the shielding curtain 55 is rolled up on the reel 54. At this time, the shielding curtain 55 does not block the recording slot 44 (at this time, the half-toothed gear 52 The half-tooth gear 52 is still meshed with the driven gear 53), and the microphone 42 can be used at this time; when the wheeled robot based on consumer complaints and services is not needed, the drive motor 51 can be started to drive the half-tooth gear 52 to rotate, so that the half-tooth gear 52 is separated from the driven gear 53, and the counterweight rod 56 gradually descends under the action of gravity (the weight of the counterweight rod 56 is greater than the resistance of the shielding curtain 55 when it rotates on the reel 54), which can drive the shielding curtain 55 to rotate on the reel 54 and gradually unfold, so as to cover the recording slot 44, thereby preventing external dust from entering the robot shell 1 through the recording slot 44.

[0035] A corresponding number of movable teeth 521 can also be installed on the flange surface of the half-toothed gear 52 through countersunk bolts 522 as needed, which can increase the number of teeth meshing with the driven gear 53, thereby increasing the distance for driving the driven gear 53 to rotate, so as to adjust the height of the rolled-up shielding curtain 55 (that is, the distance from the rolled-up shielding curtain 55 to the bottom surface of the robot housing 1); the number of movable teeth 521 is less than half of the number of teeth of the half-toothed gear 52, so that after the half-toothed gear 52 is separated from the driven gear 53, the counterweight rod 56 descends under the action of gravity, which can drive the shielding curtain 55 to rotate on the roller 54 and gradually unfold.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
