The application provides a two-sided glass wipes, and the body of wiping outward in this two-sided glass wipes can firmly adsorb on glass's surface through the anti-falling sucking disc that sets up on it when having the trend that drops, and difficult emergence is dropped, and the security performance is better.

Fig. 1 is a schematic overall structure diagram of a double-sided glass wiper provided in an embodiment of the present application, fig. 2 is a front view of an outer wiper body provided in an embodiment of the present application, fig. 3 is a sectional view taken along an AA' view in fig. 2, as shown in fig. 1 to 3, the double-sided glass wiper 100 provided in an embodiment of the present application includes an outer wiper body 10 and an inner wiper body 20 which are attracted by magnetic force, the outer wiper body 10 has a wiping surface 11 for adhering to a glass surface, the double-sided glass wiper 100 further includes an anti-drop suction cup 30, an actuator, an anti-drop sensor 40, and a controller 50.

The anti-falling sucker 30 is disposed on the outer wiper 10, and the actuator is also disposed on the outer wiper 10 and connected to the anti-falling sucker 30, and is configured to control an adsorption force between the anti-falling sucker 30 and a glass surface.

The application does not limit the setting position, mode and specific structure of the actuating mechanism on the external wiping body 10. Alternatively, as shown in fig. 1 and 3, the eraser body 10 includes a bottom case 101 and a top cover 102 covering the bottom case 101, the top cover 102 and the bottom case 101 together define an inner cavity of the eraser body 10, and the actuator can be disposed in the inner cavity, so as to fully utilize the space inside the eraser body 10 without affecting the aesthetic property of the eraser body 10.

Wherein, the anti-falling sensor 40 is arranged on the outer wiping body 10 and/or the inner wiping body 20. Specifically, the anti-drop sensor 40 is provided on one of the outer wiping body 10 and the inner wiping body 20, or the anti-drop sensor 40 is provided on both the outer wiping body 10 and the inner wiping body 20.

The controller 50 provided by the embodiment of the application is arranged on one of the outer wiping body 10 and the inner wiping body 20 and is connected with the anti-falling sensor 40 and the actuating mechanism, and the controller 50 is used for acquiring a falling sensing signal acquired by the anti-falling sensor 40 and controlling the actuating mechanism to increase the adsorption force between the anti-falling sucker 30 and the glass surface when the outer wiping body 10 is determined to have a falling trend at present according to the falling sensing signal. Therefore, the outer wiping body 10 can be firmly adsorbed on the outer surface of the glass through the anti-falling sucker 30, and is not easy to fall.

Here, the outer wiper 10 having a tendency to fall means: the outer body 10 is still attached to the outer surface of the glass in a state where no falling occurs but there is a large possibility of falling.

Here, the controller 50 may be electrically connected to the drop prevention sensor 40 and the actuator, or may be wirelessly connected, as long as the controller 50 can acquire the drop sensing signal and control the actuator.

Optionally, the controller 50 and the drop-preventing sensor 40 are both disposed on the outer wiper 10, and the controller 50, the drop-preventing sensor 40 and the actuator are all electrically connected to each other, at this time, the transmission speed of the drop-sensing signal is fast, and the response speed of the actuator is also fast.

Optionally, the controller 50 and the anti-drop sensor 40 (or the actuator) are separately disposed on the outer wiping body 10 and the inner wiping body 20, for example, the anti-drop sensor 40 is disposed on the inner wiping body 20, the controller 50 is disposed on the outer wiping body 10 and electrically connected to the actuator disposed on the outer wiping body 10, and the anti-drop sensor 40 can establish a wireless communication connection with the controller 50 through a wireless communication device to send a drop sensing signal; the controller 50 and the actuator may be connected by wireless communication via a wireless transceiver, and the controller 50 may control the actuator wirelessly. In this manner, the controller 50 and the anti-drop sensor 40 are more flexibly arranged.

The embodiment of the application does not limit the type of the anti-drop sensor 40, the setting position of the anti-drop sensor 40 is determined according to the type of the anti-drop sensor, and the anti-drop sensor 40 can conveniently acquire the drop induction signal.

Alternatively, the anti-drop sensor 40 may be an analog sensor, and the drop sensing signal collected by the anti-drop sensor 40 is a signal of the detection value. Illustratively, the analog quantity sensor may be any one of a pressure sensor, an ambient light sensor, and a displacement sensor, and the detection value is a pressure value, an ambient light brightness value, a displacement value, and the like, correspondingly. Further, the controller 50 determining whether the eraser body 10 has a falling tendency currently according to the falling sensing signal includes: when the detection value is larger than the first threshold value, determining that the outer wiping body 10 has a falling tendency currently; alternatively, when the detection value is smaller than the second threshold value, it is determined that the outer wipe body 10 currently has a falling tendency. Here, the types of the first threshold value and the second threshold value correspond to the type of the detection value.

Specifically, when the anti-drop sensor 40 is a pressure sensor, the pressure sensor may be disposed on the wiping surface 11 of the outer wiping body 10, and is configured to detect a pressure value (at this time, the detected value is a pressure value) of the outer wiping body 10 to the glass surface, because the magnitude of the friction force applied to the outer wiping body 10 is proportional to the magnitude of the pressure value, when the pressure value is smaller than the second threshold (which is a preset pressure value), it indicates that the magnetic attraction between the inner wiping body 20 and the outer wiping body 10 is smaller, and the friction force applied to the outer wiping body 10 is also smaller, and at this time, the smaller friction force may not be enough to balance the gravity of the outer wiping body 10, so that it may be determined that the outer wiping body 10 has a drop tendency at present.

The pressure sensor can also be a negative pressure sensor, and the negative pressure sensor is arranged in the anti-falling sucker 30 and used for detecting a negative pressure value in the anti-falling sucker 30, namely, a falling induction signal acquired by the negative pressure sensor is a signal of the negative pressure value, when the negative pressure value is greater than a first threshold value (for presetting the negative pressure value), the adsorption force between the anti-falling sucker 30 and the glass surface is smaller, so that the outer wiping body 10 cannot be firmly adsorbed on the glass surface and has a falling trend.

Specifically, when the anti-drop sensor 40 is an ambient light sensor, the ambient light sensor may be disposed on the wiping surface 11 of the outer wiping body 10 or the wiping surface of the inner wiping body 20, and the sensing surface of the ambient light sensor faces outward, so as to detect an ambient light brightness value outside the wiping surface, that is, a drop sensing signal collected by the ambient light sensor is a signal of the ambient light brightness value. When the external wiping body 10 moves synchronously with the internal wiping body 20 under the action of the magnetic attraction force, the wiping surfaces of the internal and external wiping bodies always keep a relative position relationship to shield most light, so that the ambient light brightness value detected by the ambient light sensor is low. When the ambient light brightness value is greater than the first threshold (which is a preset ambient light brightness value), it indicates that a large degree of misalignment has occurred between the outer wiping body 10 and the inner wiping body 20, or the inner wiping body 20 is not tightly attached to the inner surface of the glass, so that the magnetic attraction between the inner and outer wiping bodies is small, and it can be determined that the outer wiping body 10 has a falling tendency at present.

Specifically, when anti-drop sensor 40 is displacement sensor, displacement sensor can locate in the interior cavity of outer wiping body 10, still the activity is equipped with magnet assembly 13 in the interior cavity of outer wiping body 10, this magnet assembly 13 can move or move to the direction of keeping away from the glass surface to the direction of being close to the glass surface (this moment, magnetic attraction reduces), displacement sensor is used for detecting the displacement value that magnet assembly 13 removed to keeping away from the glass surface direction, the drop sensing signal that displacement sensor gathered is the signal of the displacement value of magnet assembly 13 promptly. When the displacement value is larger than the first threshold value (which is a preset displacement value), the distance between the magnet assembly 13 inside the outer wiping body 10 and the inner wiping body 20 is larger, which indicates that the magnetic attraction force between the inner wiping body 20 and the outer wiping body 10 is smaller, and thus it can be determined that the outer wiping body 10 currently has a falling tendency.

Through presetting the threshold value and comparing the detected value that anti-falling sensor 40 gathered with preset threshold value, can be accurate judge the state of external friction body 10, and then can control the execution structure when external friction body 10 has the trend of dropping in order to increase the adsorption affinity between anti-falling sucking disc 30 and the glass surface, prevent that external friction body 10 from dropping.

Alternatively, the controller 50 may be a logic controller (configured by a logic circuit) or may be a micro-program controller (storing a computer program and being capable of executing the computer program). It should be understood that the controller 50 can determine whether the eraser body 10 has a falling tendency or not and control the actuator according to the prior art.

Alternatively, the drop prevention sensor 40 may be a switching value sensor. The switching value sensor can output a switching value signal of 'on' or 'off' according to the collected falling induction signal, and then the on-off of the circuit can be controlled, namely the switching value sensor can directly control the actuating mechanism. In this case, it is understood that the anti-drop sensor 40 includes the controller 50 (or the controller 50 is integrated into the anti-drop sensor 40), and the output signal of the anti-drop sensor 40 can directly control the actuator. Illustratively, the switching value sensor may be a color sensor or a proximity switch.

Specifically, when the anti-drop sensor 40 is a color sensor, the color sensor may be disposed on the outer wiping body 10 and the sensing surface faces the inner wiping body 20, the color sensor is used to detect color information, and the drop sensing signal collected by the color sensor is a signal of the color information. The color sensor stores therein information of a preset color, which may be a color of the wiping surface of the inner wiping body 20 or a color of a color chart provided on the wiping surface of the inner wiping body 20. When the color information detected by the color sensor is different from the preset color information, that is, the sensing surface of the color sensor is not opposite to the wiping surface of the inner wiping body 20 or the color card on the wiping surface, it is indicated that the outer wiping body 10 and the inner wiping body 20 are dislocated, so that the magnetic attraction between the inner wiping body 20 and the outer wiping body 10 is reduced, and it can be determined that the outer wiping body 10 has a falling trend currently, at this time, the color sensor outputs a conducting signal (so that the circuit is conducted), and further the execution mechanism can be controlled; when the color information detected by the color sensor is the same as the information of the preset color, which indicates that the outer wiping body 10 is held opposite to the inner wiping body 20, the color sensor outputs an off signal (causes the circuit to be opened) to stop the control of the actuator.

In this embodiment, the determining, by the controller 50, whether the eraser body 10 has a falling tendency according to the falling sensing signal includes: and judging whether the detected color information is the same as the preset color information or not, and if not, determining that the outer wiping body 10 has a falling trend currently.

Specifically, the anti-drop sensor 40 is a proximity switch, which is also called a contactless travel switch, and is capable of detecting whether an object is approaching within a certain distance range and performing a switching operation. This proximity switch can locate in the interior cavity of outer body 10 of wiping to its response face is towards magnet subassembly 13, and this proximity switch is used for detecting the magnet subassembly 13 that outer body 10 internalization set up whether gets into the response within range of self, and its response within range can be apart from response face 1cm, 3cm, 5cm etc. this moment, the sensing signal that drops that anti-drop sensor 40 gathered is magnet subassembly 13 whether gets into the signal in self response within range. Illustratively, the proximity switch may be a normally open type proximity switch, i.e., the proximity switch is in an off state (i.e., outputs an off signal) when the proximity switch does not detect the magnet assembly 13; when the proximity switch detects the magnet assembly 13, it indicates that the magnet assembly 13 has moved a certain distance in a direction away from the inner wiping body 20, the magnetic attraction between the outer wiping body 10 and the inner wiping body 20 is small, and it can be determined that the outer wiping body 10 has a falling trend currently, at this time, the proximity switch becomes a closed state (outputs a conducting signal), and then the actuator can be controlled.

In this embodiment, the determining, by the controller 50, whether the eraser body 10 has a falling tendency according to the falling sensing signal includes: if the magnet assembly 13 is brought within the sensing range (i.e., the magnet assembly 13 is detected), it is determined that the eraser body 10 currently has a tendency to fall.

Optionally, the sensing surface of the proximity switch may also face the inner wiping body 20 and be used to detect whether the inner wiping body 20 enters its sensing range, and if the inner wiping body 20 does not enter its sensing range, it indicates that the outer wiping body 10 and the inner wiping body 20 are misaligned, and it may be determined that the outer wiping body 10 currently has a falling tendency, and at this time, the proximity switch outputs an on signal.

Illustratively, the proximity switch may be an electro-optical proximity switch, a capacitive proximity switch, or a hall proximity switch, and the application is not limited to the type of the proximity switch.

The switching value sensor can directly control the actuating mechanism by outputting a switching-on signal or a switching-off signal, has high response speed and timely control process, and can effectively prevent the outer wiping body 10 from falling.

When the outer wiper 10 and the inner wiper 20 are dislocated, or are far away from each other, the magnetic attraction between the inner and outer wipers is reduced, and if the degree of dislocation of the inner and outer wipers is large, the outer wiper 10 has a large possibility of falling, and the safety performance is poor. The application provides a be provided with anti-falling sucking disc 30 on double-sided glass wipes 100, actuating mechanism, anti-falling sensor 40 and controller 50, when controller 50 confirms that outer wiping body 10 has the trend of dropping in the present according to the sensing signal that drops that anti-falling sensor 40 gathered (also when the dislocation of the great degree takes place for outer wiping body in other words), can control actuating mechanism in order to increase the adsorption affinity between anti-falling sucking disc 30 and the glass surface, make outer wiping body 10 when having the trend that drops but not taking place to drop, can in time firmly adsorb on glass's surface and be difficult for dropping through anti-falling sucking disc 30. Therefore, the anti-drop sensor 40 can effectively prevent the outer wiper 10 from dropping, and the safety performance of the double-sided glass wiper 100 is improved.

By arranging the anti-falling sensor 40 and other structures on the double-sided glass wiper 100, better safety performance can be ensured without arranging a safety rope on the outer wiper body 10, and the moving range of the outer wiper body 10 is not limited due to the absence of the limitation of the safety rope, so that the movement is more flexible, and the use of a user is facilitated.

Fig. 4 is a sectional view taken along a view line BB' in fig. 2, and as shown in fig. 2 to 4, the anti-falling suction cup 30 is movably provided on the outer wiping body 10, the actuator includes a driving device 60, the driving device 60 is provided in the inner cavity of the outer wiping body 10, and the driving device 60 is used for pressing the anti-falling suction cup 30 toward the glass surface to increase the suction force of the anti-falling suction cup 30 to the glass surface.

Specifically, the controller 50 sends a control signal to the driving device 60 (e.g., causes the driving device 60 to be activated) when determining that the eraser 10 currently has a tendency to fall, so that the driving device 60 can drive the anti-drop suction cup 30 to move toward the glass surface and press the anti-drop suction cup 30 toward the glass surface to exhaust air between the anti-drop suction cup 30 and the glass surface, thereby increasing the suction force between the anti-drop suction cup 30 and the glass surface and preventing the eraser 10 from falling.

The application does not limit the concrete structure of the driving device 60 and the mode of driving the anti-falling sucker 30 to move, and does not limit the concrete structure of the anti-falling sucker 30 in the moving process.

In one possible embodiment, the drive device 60 is a linear drive, which may be, for example, a push-pull electromagnet or an electric push rod. Specifically, the driving device 60 includes a push rod 61, and the push rod 61 may be an electric push rod driven by a motor, or a push-pull rod capable of linearly reciprocating in a push-pull electromagnet.

As shown in fig. 2 and 3, the anti-falling suction cup 30 includes a suction cup body 31 and a suction cup mounting seat 32, a mounting hole 111 for accommodating the suction cup body 31 is provided on the wiping surface 11 of the outer wiping body 10, a mounting tube 112 slidably fitted with the suction cup mounting seat 32 is provided on the inner wall of the wiping surface 11, and the suction cup mounting seat 32 can slide back and forth along the axial direction of the mounting tube 112. Specifically, the mounting hole 111 is a through hole provided on the wiping surface 11, and a cylindrical opening at one end of the mounting cylinder 112 communicates with the mounting hole 111, so that the suction cup body 31 can be connected with the suction cup mounting seat 32.

As shown in fig. 3 and 4, a driving device 60 is provided at the rear end of the drop-prevention sucker 30, and a push rod 61 is telescopically movable back and forth. Here, the push rod 61 is extended forward, i.e., moved in a direction close to the glass surface, and retracted backward, i.e., moved in a direction away from the glass surface. When the controller 50 sends a control signal to the driving device 60 to extend the push rod 61 forward, the push rod 61 pushes against the rear end of the anti-falling sucker 30 to make the suction surface at the front end of the anti-falling sucker 30 protrude out of the wiping surface 11, and the anti-falling sucker 30 can be firmly sucked on the glass surface under the squeezing action of the push rod 61.

Thus, the driving device 60 and the movably arranged anti-falling sucker 30 are simple in structure and easy to realize, and the production cost of the double-sided glass wiper 100 can be effectively controlled; the way in which the drive means 60 linearly drives and presses the anti-drop suction cup 30 is also relatively simple and takes up little space.

As shown in fig. 3 and 4, a supporting seat 16 is fixedly disposed in the inner cavity of the outer wiper body 10, a driving device 60 is fixedly mounted on the supporting seat 16, and the front end of the push rod 61 faces the rear end of the anti-drop suction cup 30.

Alternatively, in the present embodiment, when the push rod 61 does not press the drop-prevention suction cup 30 in the direction of the glass surface, the drop-prevention suction cup 30 may or may not be attracted to the glass surface.

In the embodiment of the present application, the controller 50 stops the control of the actuator when it is determined that the friction body 10 does not currently have a tendency to fall from the fall sensing signal. When the outer wiping body 10 does not have a falling tendency, it is indicated that the magnetic attraction force between the outer wiping body 10 and the inner wiping body 20 is enough to ensure that the outer wiping body 10 does not fall, and at this time, the attraction force between the anti-falling sucker 30 and the glass surface does not need to be increased to avoid affecting the moving wiping process of the outer wiping body 10. For example, the controller 50 turns off the driving device 60 and the push rod 61 retracts, and the push rod 61 cancels the pressing action on the drop-preventing suction cup 30; for another example, the controller 50 may also reverse the motor driving the push rod 61 to retract the push rod 61.

Alternatively, the front end of the push rod 61 may be fixedly connected to the rear end of the anti-falling sucker 30 to synchronously drive the anti-falling sucker 30 to move back and forth when moving back and forth in a telescopic manner, so that the anti-falling sucker 30 can be firmly adsorbed on the glass surface or separated from the glass surface.

Optionally, the actuator further comprises an elastic return member 12, the elastic return member 12 being adapted to separate the drop prevention suction cup 30 from the glass surface after retraction of the push rod 61.
