A cleaner 100 according to a first aspect of the present invention, as shown in fig. 1 to 4, comprises:
a cleaning assembly 10 including a tank 11 for storing a cleaning liquid and a pump 12 connected thereto, the pump 12 being configured to pressurize the cleaning liquid to form a high pressure cleaning liquid;
a blowing assembly 20 including an air flow part 21 and a temperature adjusting part 22, the air flow part 21 being configured to compress air to form a high pressure air flow, the temperature adjusting part 22 being configured to adjust a temperature of the high pressure air flow;
wherein, the cleaning assembly 10 and the blowing assembly 20 are both aligned with the surface of the sensor through the pipeline 30.
That is, the cleaner 100 determines to work with at least one of the cleaning assembly 10 and the blowing assembly 20 to clean and blow dry the surface of the sensor according to the contamination of the surface of the sensor;
for example, the general cleaning method for stains is as follows: the cleaning assembly 10 can effectively clean the surface of the sensor through the water pump 12, and the high-pressure air flow formed by the air flow part 21 of the blow-drying assembly can be used for blow-drying water drops on the surface of the sensor;
for another example, the method of cleaning rainwater in rainy days is: the high-pressure air flow formed by the air flow part 21 of the blow-drying assembly blow-dries water drops falling or condensed on the surface of the sensor;
for another example, the way of cleaning ice, snow and frost in low temperature weather: forming high-pressure air flow by an air flow part 21 of the blow-drying assembly, and simultaneously adjusting the temperature of the high-pressure air flow by a temperature adjusting part 22 to blow the high-pressure air flow with certain temperature to the surface of the sensor, so as to quickly melt and blow-dry ice, snow and frost on the surface of the sensor;
it should be noted that, in rainy days and low-temperature days, if stains still exist on the surface of the sensor after being dried by air, due to the fact that stains exist in rainwater or in low-temperature days (ice, snow and frost), the cleaning mode of common stains is continuously repeated.
The cleaner 100 can quickly remove foreign matters and dirt on the surface of the sensor (for example, muddy water splashed on the surface of the sensor is adhered to the surface of the sensor); after the cleaning solution is cleaned, the cleaning solution remained on the surface of the sensor is quickly dried, so that the condition that the sensor cannot work in a short time due to cleaning can be avoided; in low-temperature weather (such as icing, heavy snow or frosting on the surface), the snow cover and frost condensation condensed on the surface of the sensor can be quickly melted and blown dry; under extreme weather, the sensor can quickly reach a working state under a cold vehicle state, and the performance of the sensor is ensured; in rainy days (such as light rain to heavy rain), water drops falling or condensed on the surface of the sensor are quickly dried by blowing, so that the performance of the vehicle sensor in rainy days is greatly improved.
In one example of the present invention, the blowing assembly 20 includes:
a blade;
the output shaft of the motor is coupled with the blades and is configured to drive the blades to rotate the compressed air to form a high-pressure airflow;
the rotation of the blades generates high-pressure air flow to blow into the pipeline 30 communicated with the blades;
of course, the present invention is not limited thereto, and the blowing assembly 20 may also be an air pump, which can also generate a high pressure air flow.
In one example of the present invention, the conduit 30 comprises: a main pipe part 31 and at least two auxiliary pipe parts 32 communicated with the main pipe part 31, wherein at least one auxiliary pipe part 32 is communicated with the cleaning assembly 10, and at least another auxiliary pipe part 32 is communicated with the blowing assembly 20;
by arranging the pipeline 30 with the above structure, the space occupied by the cleaner 100 can be reduced, which is convenient for the optimized design of the structure;
of course, the present invention is not limited thereto, and the cleaning assembly 10 and the blowing assembly 20 may use separate pipes 30, and by using separate pipes 30, the cleaning assembly 10 and the blowing assembly may be prevented from interfering with each other.
In one example of the present invention, the method further comprises: at least two of the one-way valves 40,
each of the check valves 40 is disposed in the secondary pipe portion 32 in such a manner that the high-pressure gas flow or the high-pressure cleaning liquid can flow only from the secondary pipe portion 32 toward the main pipe portion 31;
that is, the high-pressure air flow can only flow from the corresponding secondary pipe portion 32 to the main pipe portion 31, and the high-pressure cleaning liquid can only flow from the corresponding secondary pipe portion 32 to the main pipe portion 31, so that the high-pressure air flow is prevented from entering the secondary pipe portion 32 mounted on the cleaning assembly 10 from the main pipe portion 31 when the high-pressure air flow is used; the high-pressure cleaning liquid can be prevented from entering the auxiliary pipe arranged on the blow-drying assembly from the main pipe part 31 when the high-pressure cleaning liquid is used; avoid causing the influence each other.
In one example of the present invention, the temperature adjusting part 22 is disposed at a side of the check valve 40 adjacent to the blowing assembly 20;
therefore, the high-pressure cleaning liquid generated by the cleaning assembly 10 can be prevented from influencing the temperature adjusting part 22, and the temperature adjusting part 22 can be effectively protected.
In one example of the present invention, the main pipe portion 31 and at least two sub pipe portions 32 are connected by a multi-way joint 33;
for example, the secondary pipe portion 32 includes two, in this case, three-way joints; for another example, the sub pipe portion 32 includes three, in this case, four-way joints;
it will be appreciated that when the number of secondary duct portions 32 exceeds two, multiple wash assemblies 10 or multiple blow dry assemblies may be provided to improve the efficiency of the washing or blow drying.
That is, the pipeline 30 is a split structure, that is, the main pipe portion 31, the sub pipe portion 32 and the multi-way joint 33 are fastened and connected by the clamp 35, and of course, the blowing unit 20, the cleaning unit 10 and the sub pipe portion 32, and the nozzle 34 and the main pipe portion 31 are also connected by the clamp 35.
In one example of the present invention, the conduit 30 further comprises:
a nozzle 34 installed at a position of the pipe 30 near the sensor surface and configured to spray the high-pressure cleaning liquid or the high-pressure air in a water flow or an air flow of a prescribed shape;
the atomization quality of the high-pressure cleaning liquid and the high-pressure air flow can be improved by arranging the nozzle 34, and the cleaning and drying effects of the high-pressure cleaning liquid and the high-pressure air flow are further improved.
In one example of the present invention, the method further comprises: an adjustment mechanism 50, the adjustment mechanism 50 being configured to be capable of adjusting the switching movement of the nozzle 34 between an extended position to extend the nozzle 34 and a retracted position to retract the nozzle 34;
that is, when the nozzle 34 is in use, the nozzle 34 is moved to the extended position; when the nozzle 34 is not in use, the nozzle 34 is retracted to a retracted position; the surface of the sensor can be more accurately cleaned or dried by extending the nozzle 34, so that the waste of cleaning liquid or air blowing is avoided; the space occupied by the nozzle 34 can be reduced by constricting the nozzle 34, which is advantageous for optimizing the space.
In one example of the present invention, the adjustment mechanism 50 includes:
a driving motor 51, an output shaft of the driving motor 51 is connected with the nozzle 34, and is configured to drive the nozzle 34 to rotate and switch between an extending position and a contracting position;
specifically, as shown in fig. 2, the adjusting mechanism 50 further includes an adjusting plate 52, a rotating shaft is disposed on the adjusting plate 52, the rotating shaft is fixedly connected to the driving motor 51, the adjusting plate 52 is fixed on the nozzle, and that is, the adjusting plate 52 is driven by the driving motor 51 to rotate, so as to change the position angle of the nozzle, and the nozzle is extended and retracted by the forward and reverse rotation of the driving motor 51.
In one example of the present invention, the adjusting mechanism 50 further includes: one end of the transmission mechanism is connected with the driving motor 51, and the other end of the transmission mechanism is connected with the adjusting plate 52; the purpose of arranging the transmission mechanism can play a role in reducing the rotating speed of the driving motor 51 on one hand; on the other hand, the adjustment mechanism 50 can be locked, i.e. the position of the adjustment plate 52 is locked by the transmission mechanism in the non-operating state of the driving motor 51.
For example, the transmission mechanism is a gear pair, a gear rack and a worm gear; the input and output of the gear pair and the worm gear are rotary motion, but the input shaft and the output shaft of the worm gear are mutually vertical in space; the rack-and-pinion motion converts the input circular motion into output linear motion, and the position of the nozzle 34 is switched through the linear motion.
Of course, the driving motor 51 may be a rotary motor or a linear motor;
when the driving motor 51 is a linear motor, it may be a stepping motor or a BLDC, and the nozzle 34 is driven to rotate around the rotation shaft by the linear motion of the linear motor, so as to extend and retract.
When the driving motor is a linear motor, as shown in fig. 3, the adjusting mechanism 50 further includes: a fixed plate 53, to which the adjusting plate 52 is relatively rotatably coupled, for example, via a rotating shaft 521; wherein, the driving motor 51 is fixed on the fixing plate 53, the driving shaft 511 is connected with the adjusting plate 52, and the rotation movement of the adjusting plate 52 relative to the fixing plate 53 is realized by the linear movement of the driving motor 51.
In one example of the present invention, the adjustment mechanism 50 includes:
the telescopic piece is provided with a cylinder body and a piston rod which can stretch into the cylinder body, the piston rod is connected with the nozzle, and the telescopic motion of the nozzle can be realized through the telescopic function of the telescopic piece. It will be appreciated that in this embodiment, the mounting position of the telescopic member is perpendicular to the mounting position of the drive motor 51.
Of course, the present invention is not limited thereto, and the adjusting mechanism 50 may be a lead screw nut.
In one example of the invention, the conduit 30 is a thermal insulating pipe;
after the temperature adjusting part 22 heats the high-pressure airflow, the high-pressure airflow needs to be conveyed to the surface of the sensor from the pipeline 30, and in the process, in order to avoid heat loss of the high-pressure airflow, heat can be effectively preserved through the heat preservation pipe, so that the effects of energy conservation and environmental protection are achieved.
As a further preference, the conduit 30 is a flexible hose; the flexible hose provides increased flexibility in the relative positions of the cleaning assembly 10, the blowing assembly 20 and the nozzle 34, and also facilitates adjustment of the position of the nozzle 34 as the nozzle 34 requires switching movement between the extended and retracted positions.
In one example of the present invention, the method further comprises: a wind-collecting cover 60 is provided,
is installed between the blowing assembly 20 and the pipeline 30, and is internally formed with an air cavity, the cross-sectional area of which is gradually reduced from one side of the blowing assembly 20 to one side of the pipeline 30;
the air-collecting cover 60 is arranged between the blowing assembly 20 and the pipeline 30, so that the high-pressure air flow can be effectively prevented from generating turbulence, and the high-pressure air flow is more stable.
In one example of the present invention, the method further comprises: the control unit (70) is provided with a controller,
the controller 70 is coupled to the water pump 12, the air flow portion 21, the temperature adjustment portion 22 and the adjustment mechanism 50, and configured to control the water pump 12, the air flow portion 21, the temperature adjustment portion 22 and the adjustment mechanism 50 to perform corresponding actions;
before the cleaner 100 is used, the controller 70 controls the driving motor 51 of the adjusting mechanism 50 to drive the nozzle 34 to rotate to the extending position;
the controller 70 controls at least one of the cleaning assembly 10 and the blowing assembly 20 to work according to the pollution condition of the sensor surface so as to clean and dry the sensor surface;
for example, the general cleaning method for stains is as follows: the controller 70 can effectively clean the surface of the sensor by controlling the water pump 12, and controls the high-pressure air flow formed by the air flow part 21 of the blow-drying assembly to dry the water drops on the surface of the sensor;
for another example, the method of cleaning rainwater in rainy days is: the high-pressure air flow formed by the controller 70 controlling the air flow part 21 blows and dries water drops falling or condensed on the surface of the sensor;
for another example, the way of cleaning ice, snow and frost in low temperature weather: the controller 70 controls the airflow part 21 to form high-pressure airflow, and meanwhile, the controller 70 controls the temperature adjusting part 22 to adjust the temperature of the high-pressure airflow so that the high-pressure airflow with certain temperature is blown to the surface of the sensor to quickly melt and blow dry ice, snow and frost on the surface of the sensor;
after the cleaner 100 is used, the driving motor 51 of the adjusting mechanism 50 is controlled by the controller 70 to drive the nozzle 34 to rotate from the extended position to the retracted position.
In one example of the present invention, the temperature adjusting part 22 is a heating wire;
for example, the winding manner of the heating wire can be various forms such as a spiral type, a mosquito coil type, an array type and the like.
For another example, the heating wire may be installed at a high-speed blade position of the blowing assembly 20, or may be installed at an air outlet position.
A cleaning method of a cleaner according to a second aspect of the present invention, as described above, as shown in fig. 5, includes the steps of:
judging whether the surface of the sensor is polluted or not;
if the sensor is polluted, continuously judging whether the environmental temperature of the sensor is lower than X ℃; wherein X is a parameter which can be adjusted according to actual conditions; for example, X may be 0.
If the temperature is lower than X ℃, the temperature adjusting part 22 adjusts the temperature of the high-pressure airflow sprayed by the airflow part 21, the high-pressure airflow is blown to the surface of the sensor, and one of ice, frost and snow formed on the surface of the sensor is melted and dried;
if the temperature is not lower than X ℃, the high-pressure air flow sprayed by the air flow part 21 blows to the surface of the sensor and cleans the sensor;
judging whether the surface of the sensor is polluted again;
if the sensor is polluted, the surface of the sensor is cleaned by high-pressure cleaning liquid sprayed by the cleaning component; then the high-pressure airflow sprayed out by the blowing component blows the surface of the sensor;
judging whether the surface of the sensor is polluted or not again;
if the pollution is caused, the step is switched to the step for repeated cleaning; otherwise, finishing the cleaning.
In a specific example of the present invention, the contamination condition includes one of stain, rain, ice, snow, and frost; wherein,
when the sensor surface is polluted by rainwater or dirt, the blowing assembly 20 blows water on the sensor surface to determine whether the sensor surface is polluted, if so, the cleaning assembly 10 cleans the sensor surface, and then the blowing assembly 20 blows the sensor surface to dry; if not, finishing the cleaning;
when the sensor is one of ice, snow and frost, firstly blowing hot air by the blowing assembly 20 to melt and blow dry the ice, snow or frost on the surface of the sensor, then determining whether the surface of the sensor is polluted, if so, cleaning the surface of the sensor by the cleaning assembly 10, and then blowing the surface of the sensor by the blowing assembly 20; if not, the cleaning is finished.
In one example of the present invention, the cleaning method further includes:
if the repeated cleaning times of the surface of the sensor are more than N times, generating an alarm signal; wherein N is more than or equal to 2;
the surface remains contaminated after cleaning (indicating that the contaminants have not been effectively removed), the cleaning is complete (avoiding trapping in a dead cycle), and an alarm is given to the upper system.
That is, the cleaning direction is determined based on the contamination condition of the sensor surface to work with at least one of the cleaning assembly 10 and the blowing assembly 20 to clean and blow dry the sensor surface;
the cleaning method comprises two modes of water spray cleaning and air injection cleaning, wherein the water spray cleaning is to clean the surface of the sensor by injecting high-pressure water; the air-jet cleaning is mainly to clean the sensor by adopting an air blowing principle, and simultaneously, in order to solve the problem that the detection performance of the sensor is influenced by icing, snow accumulation or frosting on the surface in winter, a high-temperature snow melting function can be selected according to the weather condition.
A sensor-equipped vehicle according to a third aspect of the invention includes:
a sensor;
as in the case of the cleaner 100 described above,
wherein the cleaner 100 is configured to be disposed toward a sensor surface.
Cleaning the surface of the sensor by the cleaner 100 during the running of the vehicle; the cleaner 100 can avoid the reduction of the detection capability caused by the pollution of the sensor surface, and can quickly remove foreign matters and stains on the sensor surface (for example, muddy water is splashed on the sensor surface and adheres to the surface); after the cleaning solution is cleaned, the cleaning solution remained on the surface of the sensor is quickly dried, so that the condition that the sensor cannot work in a short time due to cleaning can be avoided; under low-temperature weather (such as icing, heavy snow or frosting on the surface), snow accumulated on the surface of the sensor can be quickly melted and blown dry; under extreme weather, the sensor can quickly reach a working state under a cold vehicle state, and the performance of the sensor is ensured; in rainy days (such as light rain to heavy rain), water drops falling or condensed on the surface of the sensor are quickly dried by blowing, so that the performance of the vehicle sensor in rainy days is greatly improved.
While the exemplary embodiments of the cleaner 100 and the cleaning method proposed by the present invention have been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that various modifications and changes can be made to the specific embodiments described above without departing from the concept of the present invention, and various combinations of the technical features and structures proposed by the present invention can be made without departing from the scope of the present invention, which is defined by the appended claims.
