Description

Technical Field

[0001] The present invention relates to the technical field of car washers, and in particular to a mobile vehicle-mounted car washer. Background Art

[0002] Traditional car washes typically use large gantry car washes at car washes. These machines are fixed to the car wash and are difficult to move to other areas. Vehicles must be driven to the gantry car wash for automated cleaning. If the owner is busy and unable to drive to the car wash, and cannot hand over the car keys to someone else, the car in urgent need of cleaning will not be able to be cleaned.

[0003] A Chinese utility model patent with authorization announcement number CN201685794U includes a frame, a steam delivery pipe, a steam spray gun connected to the output end of the steam delivery pipe, a steam generator, a water tank, and a water pump installed in the frame, the water inlet of the water pump is connected to the inner cavity of the water tank, the water outlet of the water pump is connected to the water inlet of the steam generator, and the steam outlet of the steam generator is connected to the input end of the steam delivery pipe. The steam generator includes a gas burner and a heat exchanger, and the gas burner is connected to the gas inlet pipe; the heat exchanger is located above the gas burner; the heat exchanger includes a metal serpentine tube and metal fins; each metal fin is welded to the metal serpentine tube; the inlet of the metal serpentine tube forms the water inlet of the steam generator, and the outlet of the metal serpentine tube forms the steam outlet of the steam generator;

[0004] Although the environmentally friendly steam car washing machine can generate a large steam pressure and can provide car washing services to car owners at their doorsteps without leaving the car wash site, the car washing machine still requires manual handheld steam spray guns to clean the vehicles to be washed. The car washing time is long and the labor intensity is high. It is impossible to achieve automatic cleaning of the vehicle surface. Especially when cleaning a vehicle to be washed that is surrounded by other vehicles, it is easy to splash the wastewater from the car wash onto other vehicles, thereby causing adverse effects. Summary of the Invention

The two water-blocking racks can drive the four first water-blocking rotating parts to rotate at the same time, and the power source is only one bidirectional drive screw. This not only reduces the setting of the power source and simplifies the equipment structure, but also realizes the synchronous adjustment of the four first water-blocking rotating parts, making the adjustment of the water-blocking unit more convenient.

[0039] The beneficial effects of the present invention are:

[0040] 1. The present invention uses a car wash unit to automatically clean the surface of a vehicle to be washed, and cooperates with a water blocking unit that is unfolded and closed outside the car wash unit and the vehicle to be washed to block and isolate sewage during car washing. When washing a vehicle to be washed near other vehicles, it can reduce or avoid splashing sewage generated by car washing onto the surfaces of other vehicles, thereby having high practical value.

[0041] 2. The present invention controls the first mounting frame to move to the upper center end of the vehicle to be washed, so that the car wash unit extends into the side of the vehicle to be washed, and the water retaining unit also extends to the side of the vehicle to be washed and is located outside the car wash unit, so as to isolate the vehicle to be washed from other vehicles next to the vehicle to be washed; the car wash unit washes the vehicle to be washed in the area covered by the water retaining unit, and the telescopic frame is telescopically adjusted according to the length and width of the vehicle, effectively solving the problem that users do not have time to go to a car wash station to wash their cars; and solving the problem that when washing cars on the spot, the washing space is small and pollutants are easily splashed onto surrounding vehicles, and the problem that it is difficult to perform automatic car washing when washing cars on the spot;

[0042] 3. The present invention can automatically adjust according to the size of the vehicle to be washed through the cooperation of the car washing unit and the water retaining unit, and has a wide range of applications. At the same time, the car washing unit and the water retaining unit can be automatically folded and retracted, which, on the one hand, reduces the floor space occupied by the mobile car washing machine when not in use, and, on the other hand, facilitates the remote movement of the mobile car washing machine and reduces obstacles.

[0043] 4. The present invention drives two water retaining racks to move toward or away from each other through a bidirectional driving screw. The two water retaining racks can simultaneously drive four first water retaining rotating parts to rotate, and the power source is only one bidirectional driving screw.

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0062] Example 1

[0063] like Figure 1-3 As shown, the present invention provides a mobile vehicle-mounted washing machine, comprising: a first mounting frame 1;

[0064] A car washing unit 2 for cleaning the surface of the vehicle is provided at the lower part of the first mounting frame 1;

[0065] The water blocking unit 3 is used to block the water splashed when the car washing unit 2 washes the vehicle. The water blocking unit 3 is arranged on the upper part of the first mounting frame 1 and is located outside the car washing unit 2; the water blocking unit 3 includes:

[0066] A telescopic frame 31 is provided on the upper portion of the first mounting frame 1 and is used to extend and cover the car washing unit 2 and the vehicle to be washed;

[0067] Water-retaining cloth 32;

[0068] The cloth rolling roller 33 is used to roll up or unfold the water-retaining cloth 32 . The cloth rolling roller 33 is rotatably arranged at one end of the telescopic frame 31 away from the car washing unit 2 .

[0069] Furthermore, the first mounting frame 1 is mounted on the washing vehicle through a cantilever 11; the washing vehicle is also equipped with a water tank, a steam generator, a blower, and a microcomputer; the washing vehicle moves the first mounting frame 1 to the top of the vehicle to be washed through the cantilever 11, and a camera 12 is installed at the lower end of the first mounting frame 1 to detect the current position of the first mounting frame 1. The position of the first mounting frame 1 is detected by the camera 12 and transmitted to the microcomputer, and the microcomputer controls the movement position of the cantilever 11 so that the first mounting frame 1 is located above the center of the vehicle to be washed; the water tank is connected to the steam generator, the first solenoid valve, and the car washing unit 2 in sequence through the steam input pipe 241 to provide steam for the car washing unit 2 to achieve steam washing; the blower is connected to the second solenoid valve and the car washing unit 2 in sequence through the air drying pipe 242. When the surface of the vehicle needs to be dried, the microcomputer starts the blower and opens the second solenoid valve and closes the first solenoid valve to provide the car washing unit 2 with dry air to dry the vehicle;

[0070] It should be noted that the microcomputer can control the opening and closing of the first electromagnetic valve, the second electromagnetic valve, the steam generator, the blower, the car washing unit 2, the water retaining unit 3, and the camera 12.

[0071] It should be noted that after the general vehicles are parked, the distance between adjacent vehicles is at least 50 centimeters away; when washing part of the vehicles in the parking lot or washing the vehicles to be washed with other vehicles parked next to them,

[0072] Many users do not have time to go to the car wash to wash their cars due to time constraints. Therefore, users order car wash services online through mobile APPs, such as Meituan, 58.com, etc., and inform the merchant of the vehicle location, license plate number and some precautions on the mobile APP, and confirm the order and payment. The merchant will then send a service personnel nearby to wash the vehicle specified by the user. Since the merchant does not have the user's vehicle key, it can only wash the car at the location of the vehicle, that is, dispatch the mobile car washing machine involved in this case to wash the vehicle on the spot. A mobile car washing machine can be equipped in a community or a commercial office circle to achieve The mobile car wash machine can clean multiple vehicles nearby in the area, saving cleaning time and reducing the time loss of round trips; conventional mobile car wash machines are manually cleaned by humans, which has low cleaning efficiency, and the vehicles to be washed are located between multiple vehicles with small gaps, making it difficult to clean quickly, and even more difficult to achieve automatic cleaning; if manual cleaning is not careful, water stains or dirt may be splashed onto adjacent vehicles that do not need to be cleaned, or other surrounding vehicles may be partially cleaned, resulting in a problem of inconsistency between the locally clean part and the dirty part of the vehicle surface, which may easily lead to civil disputes or disputes; the mobile car wash machine of the present invention uses micro The computer controls the cantilever 11 to drive the first mounting frame 1 to move to the central upper end of the vehicle to be washed, so that the car washing unit 2 extends into the side of the vehicle to be washed, and the water retaining unit 3 also extends to the side of the vehicle to be washed and is located outside the car washing unit 2 to isolate the vehicle to be washed from other vehicles next to the vehicle to be washed; the car washing unit 2 washes the vehicle to be washed in the area covered by the water retaining unit 3, and the telescopic frame 31 is telescopically adjusted according to the length and width of the vehicle, so that the water retaining unit 3 can cover the vehicle to be washed and merge it with the car washing unit 2 to reserve cleaning space; the telescopic frame 31 drives multiple cloth rolling rollers 33 to move to the four corners of the vehicle respectively, and the cloth rolling rollers 33 rotate and adjust according to the length and width of the vehicle to be washed. The length and width of the water-retaining cloth 32 can be retracted and extended to adapt to the contours of the vehicle to be washed, thereby isolating the vehicle to be washed from other surrounding vehicles. The car washing unit 2 moves along the length and width of the vehicle to clean the vehicle, avoiding or reducing the problem of water stains or pollutants splashing onto surrounding vehicles when cleaning the vehicle to be washed, improving the cleaning effect and reducing the spread of pollutants. On the one hand, it effectively solves the problem that users have no time to go to the car wash to wash their cars, and on the other hand, it solves the problem that when washing the car on the spot, the car washing space is small and pollutants are easily splashed onto surrounding vehicles, as well as the problem that it is difficult to perform automated car washing when washing the car on the spot. It has high practical application value.

[0073] Further, such as Figure 7-9 As shown, the car washing unit 2 includes:

[0074] A first telescopic car washing member 21 arranged longitudinally and connected to the first mounting frame 1;

[0075] A second telescopic car washing member 22 is disposed transversely and connected to one end of the telescopic car washing member 21;

[0076] A first car washing rotating member 23 arranged vertically and hinged to one end of the second car washing telescopic member 22;

[0077] A car washing part 24 is coaxially connected to the first car washing rotating part 23.

[0078] Furthermore, the second car wash telescopic part 22, the first car wash rotating part 23 and the car wash part 24 are all arranged in pairs, and the number is twice that of the first car wash telescopic part 21; a second car wash rotating part 25 is connected between the first car wash telescopic part 21 and the second car wash telescopic part 22; the maximum angle between the second car wash telescopic part 22 and the first car wash rotating part 23 is a right angle.

[0079] Further, such as Figure 7-9 As shown, there are two first car wash telescopic parts 21 and two second car wash rotating parts 25, and four second car wash telescopic parts 22, first car wash rotating parts 23 and car wash parts 24, so as to reduce the length of the first car wash telescopic parts 21 and the second car wash telescopic parts 22, and avoid the problem that the first car wash telescopic parts 21 and the second car wash telescopic parts 22 need to be set with a longer length, resulting in the span being too large and the second car wash telescopic parts being easily bent and damaged.

[0080] The second car wash rotating member 25 is used to drive the second car wash telescopic member 22 to rotate and adjust its position to facilitate cleaning of the front and rear positions of the vehicle to be washed, and cooperate with the first car wash rotating member 23 to adjust the rotation angle of the car wash member 24 to achieve better cleaning of the four corners and the front and rear of the vehicle to be washed.

[0081] Further, such as Figure 10-11 As shown, the first car washing rotating member 23 is provided with a first shaft 26 rotatably connected to the second car washing telescopic member 22; the second car washing telescopic member 22 is provided with a first rack 27 adjacent to the first car washing telescopic member 21;

[0082] The first car washing rotating member 23 is shortened so that the teeth provided on the first shaft 26 are close to the first rack 27 and mesh with the first rack 27 . The first car washing rotating member 23 rotates around the first shaft 26 until it is parallel to the second car washing telescopic member 22 .

[0083] It should be noted that when the second car wash telescopic part 22 shortens and drives the first car wash rotating part 23 to shrink and approach the first mounting frame 1, the first rack 27 is located above the first shaft 26, and the teeth on the first shaft 26 will engage with the first rack 27, thereby realizing the rotation of the first shaft 26 and driving the first car wash rotating part 23 to rotate around the first shaft 26 to realize the parallelism of the car wash part 24 and the second car wash telescopic part 22, realizing the automatic folding of the car wash unit 2 and facilitating its placement, so as to facilitate the long-distance movement of the mobile car-mounted car washing machine and reduce the floor space.

[0084] Example 2

[0085] like Figure 1-12 As shown, the components identical or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that: Figure 2-4 As shown in FIG. 10 , the telescopic skeleton 31 includes:

[0086] A first water-blocking rotating member 311 disposed on the upper portion of the first mounting frame 1;

[0087] A first water-blocking telescopic member 312 that rotates along with the first water-blocking rotating member 311;

[0088] The first water-blocking driving member 313 is used to drive the cloth-winding roller 33 to rotate and is hinged to the end of the first water-blocking telescopic member 312 .

[0089] Further, such as Figure 10 As shown, the first water-blocking driving member 313 includes a water-blocking sub-driving member 3131 and a first gear set 3132; the water-blocking sub-driving member 3131 drives the first gear set 3132 to rotate, thereby synchronously driving the two cloth winding rollers 33 at the end of the first water-blocking driving member 313;

[0090] It should be noted that the coverage range of the water retaining unit 3 is adjusted by adjusting the rotation angle of the first water retaining rotating part 311 and the elongation of the first water retaining telescopic part 312 to adapt to the corresponding contour of the vehicle to be washed; the water retaining unit 3 can provide precise water-blocking protection for the car washing unit 2.

[0091] Further, such as Figure 3-4 As shown, there are four first water-blocking rotating members 311; the water-blocking unit 3 further includes a second water-blocking driving member 34 for driving the four first water-blocking rotating members 311 to rotate synchronously; the second water-blocking driving member 34 includes:

[0092] Two water-blocking racks 341 arranged in a straight line and slidably mounted on the first mounting frame 1 , each of the water-blocking racks 341 being engaged with teeth mounted on two adjacent first water-blocking rotating members 311 ;

[0093] The two ends of the bidirectional driving screw 342 pass through the two water retaining racks 341 respectively.

[0094] It should be noted that, by rotating a bidirectional drive screw 342 to drive the two water-blocking racks 341 to move toward or away from each other, one water-blocking rack 341 drives the two first water-blocking rotating parts 311 to rotate and adjust the angle. The two water-blocking racks 341 can simultaneously drive the four first water-blocking rotating parts 311 to rotate, and the power source is only one bidirectional drive screw 342, which not only reduces the setting of the power source and simplifies the equipment structure, but also realizes the synchronous adjustment of the four first water-blocking rotating parts 311, making the adjustment of the water-blocking unit 3 more convenient.

[0095] Further, such as Figure 3-4 As shown in Figures 10 and 10, winding motors 36 are provided at the symmetrical centers of the four first water-blocking rotating members 31. Four ropes 361 are connected to the winding motors 36. The four ropes 361 are respectively connected to one end of the first water-blocking telescopic member 312 away from the winding motors 36 to reduce or avoid bending of the ends of the first water-blocking telescopic member 31. The process of the winding motors 36 rotating and winding the ropes 361 is adapted to the elongation of the first water-blocking telescopic member 31.

[0096] Further, such as Figure 3-4 As shown in FIG. 10 , the first water-blocking telescopic member 312 and the first water-blocking driving member 313 are hingedly connected via a hinge; the hinge comprises a first plate 314 and a second plate 315 hingedly connected to each other;

[0097] A guide rod 316 is provided on the first plate 314; a pull rope 317 is connected to the lower end of the second plate 315, and the pull rope 317 passes between the guide rod 316 and the first plate 314, the upper part of the first water-blocking rotating part 311, and is connected to the water-blocking rack 341 close to the side of the first water-blocking rotating part 311; the water-blocking rack 341 slides away from the first water-blocking rotating part 311 and drives the first water-blocking driving part 313 to rotate until it is arranged parallel to or at an acute angle to the first water-blocking telescopic part 312.

[0098] It should be noted that after washing the car, the four first water-blocking retractable parts 312 are moved close together by moving the two water-blocking racks 341 toward each other, and the two close water-blocking racks 341 pull the pull rope 317 to realize the rotation of the first water-blocking drive part 313 around the hinge of the hinge, thereby realizing the retraction of multiple first water-blocking drive parts 313 and the cloth roller 33, realizing the folding and contraction of the water-blocking unit 3, reducing the footprint of the water-blocking unit 3, and facilitating the long-distance movement of the mobile car-mounted car washing machine.

[0099] Further, such as Figure 3-4 , 10, the hinge point of the hinged member is located above the second car washing telescopic member 22; the first water-blocking telescopic member 312 is shortened to achieve the end of the cloth rolling roller 33 parallel to the first water-blocking telescopic member 312 overlapping the upper part of the second car washing telescopic member 22.

[0100] The cam 33 is moved to the upper portion of the second water-blocking telescopic member 22 when the first water-blocking telescopic member 312 is retracted. As the cam 33 is moved to the upper portion of the second water-blocking telescopic member 22 when the first water-blocking telescopic member 312 is retracted, the cam 33 is moved to the upper portion of the second water-blocking telescopic member 22 when the first water-blocking telescopic member 312 is retracted. As the cam 33 is moved to the upper portion of the second water-blocking telescopic member 22 when the first water-blocking telescopic member 312 is retracted, the cam 33 is moved to the upper portion of the second water-blocking telescopic member 22 when the first water-blocking telescopic member 312 is retracted. As the cam 33 is moved to the lower ... mobile vehicle-mounted car washing machine is retracted, the cam 33 is not conducive to walking, and the service life of the mobile vehicle-mounted car washing machine is reduced. By mounting the cam 33 on the second water-blocking telescopic member 22, the cam 33 has a place to place its free end, and is conducive to retracting the water-blocking unit 3 to a smaller volume, thereby reducing the floor space.

[0101] Further, such as Figure 4 As shown, a flexible water receiving bucket 35 is provided at the lower end of each of the water retaining cloths 32 , and a water extraction pipe 351 is connected to the bottom end of the flexible water receiving bucket 35 .

[0102] Furthermore, the other end of the water pumping pipe 351 is connected to the waste water tank, and a water pump is provided on the water pumping pipe 351;

[0103] It should be noted that if Figure 4-5 Or as shown in 12, the sewage in the flexible water receiving bucket 35 is pumped out by a water pump to avoid overflow. By setting the flexible water receiving bucket 35, the amount of pollution to the place where the vehicle is located when the mobile car washing machine washes the car on the spot is reduced or avoided, thereby improving the practicality of the mobile car washing machine; the flexible water receiving bucket 35 is pocket-shaped and made of waterproof material.

[0104] Further, such as Figure 4-5As shown in FIG12 , the flexible water receiving bucket 35 is provided with retractable support members 352 at intervals in sequence, and the support members 352 opened at the opening of the flexible water receiving bucket 35 are arranged perpendicular to the water retaining cloth 32 .

[0105] It should be noted that, by providing a retractable support member 352, the opening of the flexible water receiving bucket 35 at the lower end of the water-retaining cloth 32 is automatically opened after the cloth roller 33 is unwound, so as to receive the car wash waste water; the support member 352 is two arc-shaped rubber plates, and the two ends of the two arc-shaped rubber plates are connected. When the two arc-shaped rubber plates are not under force, the middle parts are separated from each other and the opening of the flexible water receiving bucket 35 is stretched open; or the support member 352 is a rubber spring, and the rubber spring is compressed when the cloth roller 33 reels up the flexible water receiving bucket 35.

[0106] Further, such as Figure 10-11 As shown, the car washing part 24 is a steam nozzle, and the upper end of the steam nozzle is connected to a steam input pipe 241 and an air drying pipe 242 respectively.

[0107] It should be noted that the steam input pipe 241 and the air drying pipe 242 are connected to the steam nozzle through a main pipe, the steam input pipe 241 is connected to the steam generator, and the air drying pipe 242 is connected to the blower. The first solenoid valve and the second solenoid valve are used to switch between steam cleaning and drying or to close both for use.

[0108] Furthermore, the first car wash telescopic part 21, the second car wash telescopic part 22, and the first water-blocking telescopic part 312 are all electric telescopic rods or cylinders or hydraulic cylinders; the first car wash rotating part 23 and the second car wash rotating part 25 are private service motors; the first water-blocking rotating part 311 is a motor or a rotating rod; and the water-blocking sub-driving part 3131 is a private service motor.

[0109] Working steps:

[0110] The mobile car washing machine moves to the side of the vehicle to be washed. The microcomputer controls the cantilever 11 to move the first mounting frame 1 above the vehicle to be washed. The camera 12 detects the position of the first mounting frame 1 relative to the vehicle to be washed and transmits the position to the microcomputer. The microcomputer controls the cantilever 11 to move the first mounting frame 1 directly above the vehicle to be washed.

[0111] Water retaining unit 3 expansion process:

[0112] The second water-blocking driving member 34 drives the first water-blocking rotating member 311 to rotate and expand, and the first water-blocking telescopic member 312 extends to further expand the water-blocking unit 3, and causes the cloth-rolling roller 33 to separate from the second car-washing telescopic member 22 and swing vertically under the action of gravity;

[0113] At the same time, the first water-blocking driving member 313 drives the cloth-winding roller 33 to rotate, so that the water-blocking cloth 32 is adaptively unfolded;

[0114] Car wash unit 2 deployment process:

[0115] The second car washing telescopic member 22 extends and disengages the first rack 27 from the first shaft 26 , causing the first car washing rotating member 23 and the car washing member 24 to droop and expand under the action of gravity and be located within the range enclosed by the water retaining cloth 32 ;

[0116] Car washing process:

[0117] Water or steam is introduced into the car wash part 24 to spray the vehicle to be washed. The sewage splashed by the spray is blocked by the water-blocking cloth 32 to prevent it from splashing onto adjacent vehicles. Most of the sewage falls into the flexible water receiving bucket 35 and is collected. The first car wash telescopic part 21 is extended to achieve cleaning around the entire vehicle. The rotation angle of the car wash part 24 is controlled by the first car wash rotating part 23, and the position of the second car wash telescopic part 22 is adjusted by the second car wash rotating part 25 to achieve cleaning of the head of the vehicle to be washed. Each second car wash telescopic part 22 can be controlled to retract and retract as a unit, so that the corresponding car wash part 24 is folded to meet the needs of car washing.

[0118] After the car is washed, dry air is introduced into the car washing unit 24 to dry the washed vehicle surface;

[0119] After the vehicle surface is dried, the microcomputer controls the car washing unit 2 to be folded first and the water retaining unit 3 to be folded and closed later.

[0120] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
