[0002] The three-wheeled driving floor scrubber is a modern cleaning equipment. It uses three-wheel drive and can travel flexibly in narrow spaces to improve cleaning efficiency. The operator can clean the floor while sitting. It is suitable for large-area floor cleaning. The floor scrubber can clean oil, mud and other stains on the road. In the process of cleaning the floor, the sweeper and floor scrubber are used at the same time to perform cleaning and washing work respectively.

[0003] In addition to driving in a straight line, three-wheeled driving scrubbers also involve turning during driving and use. When turning, the existing three-wheeled driving scrubbers cannot perform a certain amount of radial swing between the front and rear wheels, and the frame is prone to tilting or even overturning, making the three-wheeled vehicle unstable and even causing safety accidents.

[0027] By setting a tilt sensor on both sides of the bottom plate of the driving scrubber frame 1, when it is detected that the scrubber is tilted at a certain angle due to cleaning reasons, an alarm will be immediately sent to the controller, and the controller will start the braking system to slow down the steering wheel of the scrubber and stop;

[0028] Furthermore, tilt sensors are arranged on both sides of the bottom of the driving scrubber frame 1, which can effectively detect the tilt of the vehicle. Once the tilt exceeds the set threshold, an alarm will be immediately sent to the controller, so that the driver can be reminded to take measures in time to prevent accidents caused by the tilt of the vehicle. At the same time, the steering wheel of the scrubber can be slowly stopped through the braking system of the controller, further reducing the risk of vehicle sliding and ensuring the safety of the staff.

[0032] Furthermore, by providing an anti-rollover component that can be adjusted up and down on the rear drive shaft frame 31, when the controller receives the anti-rollover signal, the controller starts the electromagnet of the ball 352 to energize, attracting the iron plate inside the ball groove 21, so that the ball 352 is tightly attracted to the ball groove 21, and the controller controls the electric telescopic rod 343 to pull the adjustment sliding plate 34 to slide upward to compress the reset spring 341. While the adjustment sliding plate 34 slides upward, it drives one end of the adjustment rod 35 to swing upward, and the other end close to the rear wheel 2 swings downward. The connecting rod 32 slides and displaces inside the adjustment sliding through hole 351, pulling the two rear wheels to form an inner eight structure with the tops tilted inward, and anti-rollover is performed through the rear wheels of the two inner eight structures.

[0033] Example

[0034] When in use, the driving device drives the scrubber to perform normal driving and cleaning. The tilt sensor detects the tilt of the vehicle. When the scrubber tilts during the cleaning and turning process, and the tilt exceeds the set threshold, an alarm will be immediately sent to the controller, so that the driver can be reminded to take measures in time to prevent accidents caused by the tilt of the vehicle. At the same time, the steering wheel of the scrubber can be slowly stopped through the controller's braking system;

[0035] When the controller receives the anti-rollover signal, the controller starts the electromagnet of the ball 352 and energizes it, attracting the iron plate inside the ball slot 21, so that the ball 352 and the ball slot 21 are tightly attracted to each other, and the controller controls the electric telescopic rod 343 to pull the adjustment sliding plate 34 to slide upward to compress the reset spring 341. When the adjustment sliding plate 34 slides upward, it drives one end of the adjustment rod 35 to swing upward, and the other end close to the rear wheel 2 swings downward. The connecting rod 32 slides and moves inside the adjustment sliding through hole 351, pulling the two rear wheels to form an inner eight structure with the tops tilted inward, and anti-rollover is performed through the rear wheels of the two inner eight structures;

[0036] After use, the controller controls the electric telescopic rod 343 to reset, the reset spring 341 to reset, the electromagnet of the ball 352 to cut off the power, the rear wheel 2 to reset vertically, and the floor scrubber is driven to clean.

[0037] The utility model workflow:

[0038] When in use, the driving device drives the scrubber to drive and clean normally. The tilt sensor detects the tilt of the vehicle. When the scrubber tilts during the cleaning and turning process, and the tilt exceeds the set threshold, an alarm is immediately sent to the controller, which can promptly remind the driver to take measures to prevent accidents caused by the tilt of the vehicle. At the same time, the steering wheel of the scrubber can be slowly stopped through the controller's braking system. When the controller receives the anti-rollover signal, the controller starts the electromagnet of the ball 352 to energize, attracting the iron plate inside the ball groove 21, so that the ball 352 is tightly attached to the ball groove 21. The controller controls the electric telescopic rod 343 to pull the adjusting sliding plate 34 to slide upwards and compress the reset spring 341. The adjusting sliding plate 34 slides upwards while driving one end of the adjusting rod 35 to swing upwards and the other end close to the rear wheel 2 to swing downwards. The connecting rod 32 slides and moves inside the adjusting sliding through hole 351, pulling the two rear wheels to form an inner eight structure with the tops tilted inwards, and the rear wheels of the two inner eight structures are prevented from rolling over. After use, the controller controls the electric telescopic rod 343 to reset, the reset spring 341 to reset, the electromagnet of the sphere 352 to cut off the power, the rear wheel 2 to reset vertically, and the floor scrubber is driven to clean the floor.
