The invention provides a car washer (hereinafter referred to as car washer), which comprises a carrying trolley 101, a roof cleaning device 103, a car side cleaning device 104 and a drying device 107, wherein the roof cleaning device 103, the car side cleaning device 104 and the drying device 107 are arranged in a mutually separated mode, referring to figure 1.

The bearing trolley 101 is used for bearing the automobile and driving the automobile to move. After the user puts the car on the carrying trolley 101, the user can pull the hand brake to keep the car and the carrying trolley 101 relatively still, and then the carrying trolley 101 can drive the car to sequentially pass through the roof cleaning device 103, the car side cleaning device 104 and the drying device 107. When the vehicle passes through the device, the device can be opened, so that the vehicle can be washed or dried.

The roof washing device 103 may wash the top surface of the automobile. It should be noted that the "ceiling surface" to be cleaned by the roof cleaning device 103 in the present invention does not refer to only the outer ceiling surface of the cabin, and the "ceiling surface" includes the engine hood, the trunk lid, the front windshield, the rear windshield, and the outer ceiling surface of the cabin. In some embodiments, the roof wash apparatus 103 may be configured as a touchless wash apparatus. Specifically, the roof washing device 103 may include a gantry and a plurality of liquid spray nozzles installed at the top of the gantry, and the liquid spray nozzles face downward, the liquid spray nozzles being used to spray cleaning liquid and water to the vehicle passing through the gantry. The roof washing device 103 mainly washes the automobile by means of a cleaning function of a cleaning liquid and a washing function of a high-pressure water column. In other embodiments, the roof cleaning device 103 may be configured as a device for cleaning the vehicle with a brush, which is beneficial for improving the removal of stubborn dirt on the surface of the vehicle. Referring to fig. 7 and 8, the roof washing device 103 includes a first base frame 401, a first motor 502, and a cross brush 402; the first base frame 401 is erected on the ground, and the first motor 502 and the transverse brush 402 are both mounted on the first base frame 401. The transverse brush 402 is disposed transversely (i.e., the rotating shaft of the transverse brush 402 is disposed transversely), and the first motor 502 is used to drive the transverse brush 402 to rotate, so that the transverse brush 402 brushes the car.

The vehicle-side cleaning device 104 is mainly used for cleaning the surfaces of both the left and right sides of the automobile. The vehicle-side washing device 104 may also be provided as a non-contact type washing device, that is: the car side cleaning device 104 includes a gantry and a plurality of liquid nozzles installed at the side of the gantry and facing the space in the center of the gantry. In other embodiments, the vehicle-side washing device 104 may also be configured as a device that brushes the vehicle with a brush. Referring to fig. 9 and 10, the vehicle-side washing device 104 includes a second base frame 601, a second motor 701, and a vertical brush 602; the second base frame 601 is erected on the ground, and the second motor 701 and the upright brush 602 are both mounted on the second base frame 601. The vertical brush 602 is arranged longitudinally (the rotating shaft of the vertical brush 602 is arranged longitudinally), and the second motor 701 is used for driving the vertical brush 602 to rotate, so that the vertical brush 602 brushes the automobile. As for the front and rear end surfaces of the automobile, it is conceivable to perform cleaning with the roof cleaning device 103, and it is also conceivable to perform cleaning with the vehicle side cleaning device 104.

The drying device 107 may remove water from the surface of the vehicle by wiping or air drying. For example, referring to fig. 12, in some embodiments, the drying device 107 includes a third base frame 901 and a fan 902, the fan 902 is mounted on the third base frame 901, and an outlet of the fan 902 faces the vehicle. Still alternatively, in other embodiments, the drying device 107 includes a third base frame 901 and a plurality of drying cloths, the upper ends of the drying cloths are connected to the top of the third base frame 901; when the vehicle passes through the drying device 107, the hanging wiper contacts the vehicle body and absorbs water from the vehicle body, and when the vehicle moves relative to the wiper, the wiper acts to wipe the water from the vehicle body. Relatively speaking, the drying device 107 for drying the automobile by using the drying cloth has a simpler structure and lower cost; adopt fan 902 to carry out air-dried drying device 107 to the car, the dewatering effect is better.

The load-bearing trolley 101 can be set as an RGV trolley (Rail Guided Vehicle), i.e. a Rail needs to be installed on the ground, and the wheels of the RGV trolley are arranged on the Rail; accordingly, the track should pass through the roof washing device 103, the vehicle side washing device 104, and the drying device 107. In addition, the load carrier 101 may also be configured as an AGV. The AGV can be guided by electromagnetic induction guidance, magnetic tape guidance, optical guidance and the like, so that the AGV moves according to a specific path. For the guidance mode of electromagnetic induction guidance, low-voltage cables need to be embedded in an installation site of the car washer according to a preset movement path of the AGV, an induction coil is arranged in the AGV, and the intensity difference of electromagnetic signals received by the AGV can reflect the degree of self deviation of the path. The automatic control system of the AGV trolley can control the steering of the vehicle according to the deviation, so that the AGV trolley can automatically track the set path. For magnetic tape guidance, a metal magnetic tape is required to be attached to the ground according to a preset motion path of the AGV, a magnetic sensor is arranged on a vehicle, and the AGV controls a steering motor through magnetic field deviation to adjust the driving direction of the vehicle, so that automatic tracking of the AGV to the set path is ensured. Similarly, the optical guidance method requires that strips of reflective material be attached to the ground along a predetermined path, and that a light source and a light sensor be provided on the AGV. The specific structure and control algorithm of AGV (automated Guided vehicle) is well known in the art and is not described in detail herein. To pass an AGV carriage through a device, it is necessary to pass a guide member such as a cable or a magnetic tape through an area where the corresponding device is located. In addition, an IGV (Integrated Guided Vehicle) with higher flexibility can be adopted, the IGV mainly depends on natural contour navigation, and laser radar is used for realizing positioning without arranging a rail or a guide component on the ground.

The cost of providing the guide member is relatively lower than the cost of providing the physical rail; and under the condition that the moving path of the bearing trolley 101 is complex, the staggered arrangement of the rails is complex, if the bearing trolley 101 is set as an AGV trolley, the staggered arrangement of the guide parts is simpler, and the field arrangement of the car washer is more convenient. Furthermore, the cost of AGV carts is lower relative to IGV carts.

In short, in order to make the carrying trolley 101 move along a preset path, a track needs to be installed on the ground, or a metal tape and a reflective material tape need to be attached, or a low-voltage cable needs to be embedded in the field; however, in either method, excavation of a site in a large area is not required (even if cables are embedded, excavation of a site in a small area is required).

In addition, the roof cleaning device 103, the vehicle side cleaning device 104 and the drying device 107 are arranged in a split manner, so that the relative position arrangement flexibility among the three devices is higher, and the site adaptability of the vehicle washing machine is stronger. For example, referring to fig. 1, when the field length is long, the roof washing device 103, the side washing device 104, and the drying device 107 may be arranged along a straight line, and accordingly, the carrying cart 101 may be moved along a straight line so as to pass through the three devices. Referring to fig. 2 and 3, when the field is short in length, the positions of some of the devices can be adjusted to fit the field, for example, the entire car washer can be set in an L-shaped or U-shaped distribution, and the movement path of the carriage 101 can be adjusted accordingly (the dashed arrow in fig. 2 and 3 indicates the movement path of the carriage 101).

In conclusion, the car washer provided by the invention does not need to excavate a field in a large area, needs less field transformation, and is beneficial to improving the convenience of field installation of the car washer and reducing the cost of field installation of the car washer. In addition, based on the split arrangement among the devices and the flexibility of the path arrangement of the carrying trolley 101, an installer can flexibly adjust the relative positions of the devices in the car washer so as to enable the car washer to adapt to different fields, and therefore the car washer provided by the invention has the advantages of strong flexibility of arrangement and strong adaptability to fields.

Referring to fig. 1, in some embodiments, the car washer further includes a coating device 106, when the carriage 101 drives the car to pass through the coating device 106, the coating device 106 is used for coating the car, and the roof cleaning device 103, the car side cleaning device 104, the drying device 107 and the coating device 106 are separately arranged. After the automobile is cleaned, the automobile can be coated, and the automobile paint can be protected by the film coated on the automobile body.

The principle of coating is that a coating liquid is sprayed onto an automobile, and a coating film is formed after the coating liquid adhering to the automobile body solidifies. Referring to fig. 11, the coating device 106 includes a fourth base frame 801, a coating nozzle 802, a reservoir tank, a delivery pipe, and a driving pump. The coating nozzle 802 is mounted on the fourth base frame 801, the liquid storage tank, the delivery pipe and the driving pump may be disposed inside the fourth base frame 801 (not specifically shown), the driving pump is mounted on the delivery pipe, and the coating nozzle 802 and the liquid storage tank are connected to the delivery pipe. Under the action of the driving pump, the coating liquid in the liquid storage tank flows to the coating nozzle 802 along the delivery pipe and is finally sprayed out of the coating nozzle 802.

It should be noted that the coating solution may be a water-soluble coating solution, and accordingly, the coating may be performed when water remains on the vehicle body. Referring to fig. 1, after the coating device 106 sprays the coating liquid on the vehicle body, the carrying trolley 101 may drive the vehicle to the drying device 107, and the drying device 107 air-dries the vehicle, so as to solidify the coating liquid. In the case where the coating device 106 is provided, it is not suitable to use the drying device 107 of wiping type because the wiping cloth will simultaneously wipe off the coating liquid and affect the coating effect.

In other embodiments, based on fig. 1, if the coating liquid is required to be sprayed while the vehicle body is in a dry state, the coating device 106 may be disposed behind the drying device 107, and after the vehicle is cleaned and dried, the vehicle may be coated again by a car washer. If the relative positions of the coating device 106 and the drying device 107 in the car washer are still arranged as shown in fig. 1, after the coating solution is sprayed onto the car body, the carrying cart 101 can also be reversed to move the car to the drying device 107, so that the drying device 107 can dry the car.

Before the horizontal brush 402 and the vertical brush 602 start to brush, water and cleaning liquid need to be sprayed to the automobile; after the brushing is finished, water needs to be sprayed to the automobile so as to wash away dirt and foam on the automobile. Referring to fig. 1, in some embodiments, the car washer includes a pre-washing device 102 and a rinsing device 105 (in the case where the car is brushed by the roof washing device 103 and the car side washing device 104 using brushes), and six devices, namely, the pre-washing device 102, the roof washing device 103, the car side washing device 104, the drying device 107, the plating device 106, and the rinsing device 105, are provided separately.

The prewashing device 102 is provided with a plurality of spray heads, wherein one part of spray heads is used for spraying water to the automobile, and the other part of spray heads is used for spraying cleaning solution to the automobile; similarly, the flushing device 105 has a plurality of spray heads for spraying water. The pre-washing device 102 and the rinsing device 105 are similar to the coating device 106 in specific structure: a spray head can be arranged on a gantry, and the position of the spray head on the gantry is similar to the position of the coating nozzle 802 on the fourth pedestal 801 in fig. 11; a liquid storage container, a transfusion pipeline and a pump for supplying liquid to the spray head can be arranged in the portal frame.

In other exemplary embodiments, spray heads for spraying water and cleaning liquid may also be integrated in the roof washing device 103 and in the side washing device 104. Compared with the roof cleaning device 103 integrated with a nozzle for spraying water and cleaning liquid, the arrangement of the independent pre-cleaning device 102 can reduce the structural complexity of the roof cleaning device 103 and the volume of the roof cleaning device 103, so that the situation that the roof cleaning device 103 is too large and the arrangement flexibility of the car washer is reduced is avoided. The provision of a separate flushing device 105 makes it possible to reduce the structural complexity of the vehicle-side cleaning device 104 and the size of the vehicle-side cleaning device 104, compared to the integrated arrangement of spray heads for spraying water in the vehicle-side cleaning device 104, in order to avoid the size of the vehicle-side cleaning device 104 being too large and the flexibility of the arrangement of the vehicle washing machine being reduced.

Sensors (e.g., photoelectric sensors) may be provided in each device, and when a sensor detects the cart 101 or a vehicle located on the cart 101, the corresponding device may begin to operate. For example, when a sensor in the pre-wash apparatus 102 detects the front end of the vehicle, the pre-wash apparatus 102 begins spraying water and cleaning solution. Further, when the lateral brush 402 or the vertical brush 602 rotates, the brush is scattered, and if the roof washing device 103 and the vehicle side washing device 104 are too close to each other, the brush of the lateral brush 402 tends to make a sensor in the vehicle side washing device 104 erroneous judgment, and if the vehicle side washing device 104 and the flushing device 105 are too close to each other, the brush of the vertical brush 602 tends to make a sensor in the flushing device 105 erroneous judgment. Therefore, a certain distance is provided between the roof washing device 103 and the vehicle side washing device 104 so that the brush of the horizontal brush 402 does not enter the detection range of the sensor of the vehicle side washing device 104; a distance is also provided between the vehicle-side washing device 104 and the flushing device 105, so that the bristles of the upright brush 602 do not enter the detection range of the flushing device 105. In addition, a larger distance is reserved between the roof cleaning device 103 and the vehicle side cleaning device 104, so that the collision and friction between the bristles of the transverse brush 402 and the bristles of the vertical brush 602 can be avoided, the collision of the bristles between different brushes is reduced, and the service life of the brushes can be prolonged.

Next, the structures of the roof washing device 103, the vehicle-side washing device 104, and the drying device 107 are supplemented.

In some embodiments, the roof cleaning device 103 further includes a first displacement mechanism mounted to the first base frame 401 for driving the cross brush 402 to move up and down relative to the first base frame 401 to flexibly adjust the height of the cross brush 402, thereby adapting the cross brush 402 to different vehicle shapes and enabling the vehicle to pass through the roof cleaning device 103. For example, the first displacement mechanism may include an air cylinder or a hydraulic cylinder, a piston rod of the air cylinder or the hydraulic cylinder is connected to the horizontal brush 402, and the horizontal brush 402 can be lifted and lowered as the piston rod is extended and retracted. Alternatively, referring to fig. 8, the first displacement mechanism includes a lift motor 506, belts 503 (two in total), a guide wheel 504, a pulley 505, and a mounting bracket 501. The two ends of the horizontal brush 402 are rotatably connected to the mounting frames 501, each mounting frame 501 is connected with a belt 503, one end of each belt 503 is connected with the horizontal brush 402, the other end of each belt 503 is fixedly connected with the belt pulley 505 after bypassing the guide wheel 504, and the guide wheel 504 is rotatably connected with the first base frame 401. When the lifting motor 506 drives the pulley 505 to rotate, the length of the part of the belt 503 wound on the outer periphery of the pulley 505 is increased, and the transverse brush 402 is lifted; when the pulley 505 rotates in the reverse direction, the horizontal brush 402 descends.

Similarly, the vehicle-side cleaning device 104 further includes a second displacement mechanism, which is mounted on the second base frame 601 and is used for driving the vertical brush 602 to move transversely relative to the second base frame 601, so as to flexibly adjust the position of the vertical brush 602, thereby enabling the vertical brush 602 to adapt to the appearance of different vehicles and enabling the vehicles to pass through the vehicle-side cleaning device 104. For example, referring to fig. 10, the second displacement mechanism includes a guide rail 603, a moving base 702, a driving wheel 704, a driven wheel 705, and a traverse motor 703. The vertical brush 602 is connected to the moving base 702, and the driving wheel 704 and the driven wheel 705 are both mounted on the moving base 702 and can roll along the guide rail 603, so that the moving base 702 can slide relative to the guide rail 603. The driving wheel 704 is driven to rotate by the power of the traverse motor 703, so that the moving base 702 and the vertical brush 602 mounted on the moving base 702 move together along the guide rail 603.

Referring to fig. 12, in some embodiments, the drying device 107 includes three fans 902, wherein one fan 902 is a top fan 903 and the other two fans 902 are side fans 904. The top fan 903 is installed at the top of the third base frame 901, and an air outlet 905 of the top fan 903 faces downwards; the two side fans 904 are respectively installed at two sides of the third base frame 901, and air outlets 905 of the two side fans 904 are oppositely arranged. The arrangement can reduce dead angles which are not blown to the automobile by wind, and improve the drying effect of the automobile.

Referring to fig. 4, the present invention further provides a car washing system, which includes a plurality of carrying trolleys 101 and a plurality of car washing queues 201, wherein each car washing queue 201 includes a pre-washing device 102, a roof washing device 103, a car side washing device 104, a washing device 105, a coating device 106 and a drying device 107 (the devices are arranged separately), and the car washing queues 201 are arranged side by side. In this case, the carrying cart 101 can be reasonably scheduled to go to the empty car wash queue 201 according to the working conditions of the car wash queues 201, so as to reduce the waiting time of car owners. The previous car is in the left carwash queue 201 for cleaning, and the next car can go to the right empty carwash queue 201 for cleaning. One simple way to determine whether a car is in the car wash queue 201 is to: if a car is detected by a sensor of one of the devices in a car wash queue 201, it means that a car is in the car wash queue 201. If the preceding vehicle is already at a device (for example, the drying device 107) on the left side of the vehicle wash queue 201 that is located further back, the following vehicle can also enter the left side vehicle wash queue 201 directly for washing, since the preceding vehicle should already leave the drying device 107 when the following vehicle travels to the drying device 107.

In addition, in the case where a plurality of carwash queues 201 are arranged side by side, the car may be moved out of the interval between two devices of one of the carwash queues 201 and moved into the other carwash queue 201, so as to reduce the waiting time before the car goes to one device.

For example, in some embodiments, the spacing between the flushing device 105 and the coating device 106 in the same carwash train 201 allows the cart 101 to be loaded with cars in and out. Assume a situation where: at a certain time, there are 3 cars (referred to as car a, car B, and car C, respectively) in the car washer, car a being located at the drying device 107 of the left side wash queue 201, car B being located at the car side washing device 104 of the right side wash queue 201, and car C being located at the washing device 105 of the left side wash queue 201.

Referring to fig. 5, the usual movement path of the load carrier 101 in the same carwash train 201 is shown by the dashed arrow a.

If the car C does not need to be coated and the car a cannot be air-dried in a short time, the carrying trolley 101 carrying the car C may leave the left car wash queue 201 from the gap between the flushing device 105 and the coating device 106 of the left car wash queue 201 and enter the right car wash queue 201, and then proceed to the drying device 107 of the right car wash queue 201 (the carrying trolley 101 carrying the car C may enter the right car wash queue 201 from the gap between the flushing device 105 and the coating device 106 of the right car wash queue 201. the specific moving path of the carrying trolley 101 is shown by the dotted arrow b, and when the carrying trolley 101 passes through the coating device 106 in the right car wash queue 201, the coating device 106 is not activated.

In some embodiments, if the interval between the drying device 107 and the coating device 106 is large enough and the interval between two adjacent car wash queues 201 is large enough in the same car wash queue 201, the car C and the carrying cart 101 carrying the car C may be transferred from the left car wash queue 201 into the interval between the two car wash queues 201, and then from the interval between the drying device 107 and the coating device 106 into the right car wash queue 201 (as indicated by the dashed arrow C).

It should be noted that, in order to allow the car and the carrying trolley 101 to pass through, when designing the distance between the drying device 107 and the coating device 106, the distance between the rinsing device 105 and the coating device 106, and the distance between the adjacent car wash queues 201, not only the width of the car and the carrying trolley 101 but also the turning radius of the car and the carrying trolley 101 should be considered, so as to prevent the car or the carrying trolley 101 from colliding with the devices in the car wash queues 201 when transferring. For example, if the turning radius of the carrying cart 101 is R, the distance between the drying device 107 and the coating device 106, the distance between the rinsing device 105 and the coating device 106, and the distance between adjacent car wash queues 201 may be set to be not less than 2R. Further, the parts (metal tape, light reflecting material tape, cable, etc.) for guiding the carriage 101 should also pass through the positions where the above-described intervals are located.

In the case where the coating time of the coating device 106 is short and the brushing time of the roof cleaning device 103 and the car side cleaning device 104 is long, the car washing system in fig. 5 can be adjusted to: the plurality of car washing queues 201 can share the coating device 106, so that the cost of the car washing system is saved under the condition that the whole car washing efficiency is basically unchanged. Referring to fig. 6, the car washing system includes a carrying trolley 101, a pre-washing device 102, a roof washing device 103, a car side washing device 104, a washing device 105, a coating device 106 and a drying device 107; the number of the carrying trolleys 101, the prewashing device 102, the roof cleaning device 103, the vehicle side cleaning device 104, the flushing device 105 and the drying device 107 is the same, 2 (the carrying trolleys are not shown in fig. 6) are arranged, and 1 coating device 106 is arranged. The dashed arrow in fig. 6 indicates the moving path of the carrying cart 101, and comparing fig. 5 and fig. 6, the car washing system shown in fig. 6 is equivalent to that two adjacent car washing queues 201 in fig. 5 share one coating device 106. Fig. 6 shows a simpler case, in other embodiments, the number of the pre-washing device 102, the roof washing device 103, the side washing device 104, the rinsing device 105 and the drying device 107 may be increased, and the number of the coating devices 106 may be increased (although the number of the coating devices 106 is less than the number of the drying devices 107). In addition, the coating device 106 in the car washing system may be shared by three car wash queues 201 sharing one coating device 106, and the three car wash queues 201 sharing two coating devices, which are not listed here.
