When the sensor detects that the obstacle is located in the first detection area and the distance change value between the obstacle and the fuselage is less than a preset distance, the sensor sends the first reminder signal, the controller receives the first reminder signal, and controls the fuselage to perform a corresponding shutdown response action.

[0028] As can be seen from the background technology, the structure of existing floor scrubbers still needs to be improved.

[0029] Currently, the operator of a push-type floor scrubber cleans while standing behind it, the operator of a stand-on floor scrubber cleans while standing at the rear of the machine, and the operator of a ride-on floor scrubber sits in the cab.

[0030] The inventors found that during operation, a certain blind spot will be generated in front, and there may be imperceptible obstacles such as steps in the blind spot, which may cause the machine to directly collide with the obstacle or fall, causing damage to the machine or the obstacle, and even if the machine falls from a height, it may cause casualties.

[0031] The inventors have found that by using sensors to form a detection area in the forward direction of the machine body, when an obstacle falls into the detection area, the sensor will send a warning signal; when the anti-fall sensor detects a height difference in the forward direction of the machine body, the anti-fall sensor will send a fall signal. At this time, when the controller receives the warning signal or the fall signal, it can control the machine body to make a corresponding response action, thereby improving the interaction ability of the floor scrubber with the outside world and the operator during use. At the same time, the detection area formed in the forward direction of the machine body is used to eliminate the operator's blind spot, effectively avoiding the risk of the floor scrubber colliding with obstacles or the floor scrubber falling, thereby protecting pedestrians, operators, customer sites and floor scrubbers, and improving the service life and safety of the floor scrubber, and having a wider range of uses.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] First, please refer to Figure 1 or Figure 2 as well as Figure 6 and Figure 7 The floor scrubber includes a body 9, a sensor 1, an anti-fall sensor 4 and a controller.

[0034] In this embodiment, the sensor 1 and the anti-drop sensor 4 are both fixed on the fuselage 9, the controller is located inside the fuselage 9 and is electrically connected to the fuselage 9, and the sensor 1 and the anti-drop sensor 4 are electrically connected to the controller respectively.

[0035] In this embodiment, the sensor 1 forms a detection area in the forward direction of the fuselage 9, which is used to detect when an obstacle enters the detection area, and the sensor 1 sends a reminder signal; when the anti-fall sensor 4 detects that there is a height difference in the forward direction of the fuselage 9, the anti-fall sensor 4 sends a fall signal, and the controller receives the reminder signal or the fall signal, and controls the fuselage 9 to make a corresponding response action; the interaction ability of the floor scrubber with the outside world and the operator during use is improved, and at the same time, the detection area formed in the forward direction of the fuselage 9 is used to eliminate the operator's blind spot, effectively avoiding the risk of the floor scrubber colliding with obstacles or the floor scrubber falling, thereby realizing protection of pedestrians, operators, customer sites and floor scrubbers, and improving the service life and safety of the floor scrubber, and having a wider range of uses.

[0036] In this embodiment, the height difference is the negative height difference between the surface detected by the anti-fall sensor 4 and the ground, that is, when the anti-fall sensor 4 detects that there is a pit or a downward step in the forward direction of the fuselage 9, the anti-fall sensor 4 will send an anti-fall signal. When the controller receives the anti-fall signal, it will immediately stop the floor scrubber to minimize the risk of the floor scrubber falling from a height. It is particularly suitable for places with stairs and platforms, such as station platforms, etc.

[0037] In this embodiment, the sensor 1 includes one or a combination of ultrasonic radar, vision system, laser radar and infrared sensor 1.

[0038] Specifically, the ultrasonic radar detects the distance of obstacles around the floor scrubber, enabling the floor scrubber to avoid obstacles; the visual system detects the shape of obstacles around the floor scrubber, enabling obstacle avoidance warning reminders; the laser radar detects the distance of obstacles around the floor scrubber, enabling the floor scrubber to avoid obstacles; the infrared sensor 1 detects the distance of obstacles around the floor scrubber, enabling the floor scrubber to avoid obstacles.

[0039] In this embodiment, the body 9 includes a sewage tank 10 and a clean water tank 5 matched with the sewage tank 10 , and the sensor 1 is fixed on the sewage tank 10 or on the clean water tank 5 .

[0040] For details, please refer to Figure 1 or Figure 2 , the sensor 1 is fixed on the clean water tank 5.

[0041] In some embodiments, the sensor 1 may also be fixed on the sewage tank 10 .

[0042] In this embodiment, please refer to Figure 1 or Figure 2 as well as Figure 4 or Figure 5 , further comprising: a safety marker light 3 fixed on the fuselage 9, the safety marker light 3 forming a fan-shaped or semi-elliptical outline in the forward direction of the fuselage 9.

[0043] In this embodiment, the safety marker lights 3 are used to remind pedestrians to keep a safe distance from the floor scrubber.

[0044] In this embodiment, there are multiple sensors 1, and each sensor 1 forms a unit detection area in the forward direction of the body 9. There is overlap between adjacent unit detection areas, the purpose of which is to eliminate the blind spot in front of the operator and improve the safety of the floor scrubber.

[0045] In this embodiment, please refer to Figure 6 or Figure 7 The detection area includes a first detection area I, a second detection area II and a third detection area III. The second detection area II is located between the first detection area I and the third detection area III. The distance between the first detection area I and the fuselage 9 is smaller than the distance between the second detection area II and the fuselage 9, which is smaller than the distance between the third detection area III and the fuselage 9.

[0046] In this embodiment, the reminder signal includes a first reminder signal. When the sensor 1 detects that the obstacle is located in the first detection area I and the distance change value between the obstacle and the fuselage 9 is less than the preset distance, the sensor 1 sends the first reminder signal, the controller receives the first reminder signal, and controls the fuselage 9 to perform a corresponding shutdown response action.

[0047] Specifically, when the pedestrian or operator does not take any action, the innermost area of the sensor 1, namely the first detection area I, detects an object, and when it detects that the distance change value exceeds the set value, the controller controls the floor scrubber to stop automatically.

[0048] In this embodiment, when the sensor 1 detects that the obstacle is located in the first detection area I and the distance change value between the obstacle and the fuselage 9 is within the range of the preset distance, the sensor 1 sends the first reminder signal, the controller receives the first reminder signal, and controls the fuselage 9 to perform a corresponding non-stop response action.

[0049] Specifically, since the floor scrubber needs to clean the floor close to the wall, it only detects objects within the first detection area I, but the detection distance is always within the preset distance range. The controller then determines that the object is a wall or an object parallel to the floor scrubber, and the floor scrubber does not stop and continues to clean normally.

[0050] In this embodiment, the sensor 1 detects the distance value between the obstacle and the fuselage 9, and the controller receives the distance value and compares the distance value with the preset distance. After comparing multiple distance values, if the distance values are all within the preset distance, the obstacle is determined to be a wall; otherwise, the obstacle is determined not to be a wall.

[0051] In this embodiment, the fuselage 9 has a response device, which is electrically connected to the controller. The response device includes a breathing light 2, and the reminder signal also includes a third reminder signal. When the sensor 1 detects that the obstacle is located in the third detection area III, the sensor 1 sends the third reminder signal, and the controller receives the third reminder signal and controls the breathing light 2 to start making a corresponding flashing response action.

[0052] In this embodiment, the color of the breathing light 2 is changeable. In typical applications, the red light indicates an alarm, the yellow light indicates a reminder, and the green light indicates a normal state.

[0053] Specifically, when a pedestrian or an obstacle is detected in the outermost third detection zone III by the sensor 1 , the breathing light 2 starts to flash to remind the pedestrian.

[0054] In this embodiment, the response device also includes a vibration motor 7 and a speaker 8, and the reminder signal also includes a second reminder signal. When the sensor 1 detects that the obstacle is located in the second detection area II, the sensor 1 sends the second reminder signal. The controller receives the second reminder signal and controls the breathing light 2 to respond by flashing at an accelerated frequency, and controls the vibration motor 7 to respond by vibrating and controls the speaker 8 to respond by emitting a reminder voice.

[0055] Specifically, when pedestrians or obstacles continue to approach the second detection zone II, the flashing frequency of the breathing light 2 will accelerate, and at the same time the vibration motor 7 will vibrate and the speaker 8 will work to emit a reminder voice. Through light interaction, voice interaction and tactile interaction, pedestrians and operators are reminded to the greatest extent. Since the detection area is in the second detection zone II of the sensor 1 area, the pedestrians and operators have a certain amount of time to react and deal with the reminder of the floor scrubber, thereby further protecting pedestrians and the floor scrubber.

[0056] In this embodiment, when the anti-drop sensor 4 sends a drop signal, the controller receives the drop signal, controls the body 9 to make a corresponding shutdown response, and controls the speaker 8 to make a response action of issuing a reminder voice.

[0057] In this embodiment, an operating assembly 6 fixed to the body 9 is further included, and the vibration motor 7 and the speaker 8 are installed in the operating assembly 6 .

[0058] In this embodiment, the operating component 6 includes a handle or a steering wheel of the floor scrubber.

[0059] In this embodiment, it further includes: a floor wiping component located at the bottom of the fuselage 9, and the anti-fall sensor 4 is located at the connection between the fuselage 9 and the floor wiping component.

[0060] Specifically, the floor wiping assembly 12 includes a brush plate, and the safety marker light 3 is installed on the outside of the brush plate and in the forward direction of the fuselage 9. The brush plate is a moving rotating component. The outline of the safety marker light 3 can give pedestrians a visual reminder, greatly reducing the possibility of collision and mechanical rotation injury, and also can provide the operator with a position reference.

[0061] In this embodiment, the mopping component 12 further has an auxiliary wheel 11 in the forward direction of the body 9, and the forward direction of the body 9 is perpendicular to the axial direction of the auxiliary wheel 11. The method for judging whether an object is parallel to the floor scrubber includes judging that when the object is parallel to the axial direction of the auxiliary wheel 11, the object is parallel to the floor scrubber.

[0062] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
