[0033] Hereinafter, the present invention will be further explained:
[0034] The object of the present invention is to provide a brushless car washing machine that can achieve close cleaning of the top spray bar and the upper surface of the vehicle body, the left and right vertical spray bars and the side of the vehicle body, and the time is shorter. As we all know, the cleaning effect of the high-pressure water jet is directly related to the working distance. In actual work, after the high-pressure water jet comes out of the nozzle, it is appropriate that the distance from the surface to be acted on is about 25 cm, and the impact force will attenuate if it is farther, and the ideal high-pressure cleaning effect cannot be achieved. If a car washing machine is designed to wash 2 meters high cars, and the height of the bonnet of the car being washed is 85 cm, the high-pressure water from the nozzle of the top spray rod will be the end of the force when it reaches the upper surface of the car body. The cleaning effect is very unsatisfactory, and the energy consumption is greatly increased. In particular, if a high-pressure air nozzle is installed on the top spray rod to dry the surface of the car body, because the air jet comes out of the nozzle, its attenuation is much faster than the water jet, and a fixed top spray rod must be used to blow It is not technically feasible to dry the water stains on the upper surface of the car body.
[0035] In order to keep the top spray rod and the left and right vertical spray rods at a proper distance from the body, it is necessary to know the contour curve data such as the height of the car. Specifically, the vehicle height value at any cross section of the vehicle body, the minimum distance between the two sides of the vehicle body at that section and the suspension brackets on both sides must be known, and the position of the top spray bar and the left and right vertical spray bars must be effectively measured and controlled, and The application of these data must be based on the position of the beam at the time of measurement, combined with the specific location of the vehicle parked, and calculated to obtain the position data of the beam relative to the vehicle being cleaned.
[0036] The invention uses the cooperation of the detector and the program control system to measure and determine the actual position of the crossbeam, provide reference coordinates for the measurement and application of the body contour data, and measure the positions of the top spray bar, the left vertical spray bar, and the right vertical spray bar. The movement direction and movement distance are calculated by the pulse value of the stepping motor, and the movement control instruction is issued by the program control system. Among them, the controller can be an ultrasonic ranging sensor, a laser ranging sensor or an infrared ranging sensor.
[0037] Take the cleaning process of the car washing machine (that is, the car washing device, the same below) from the rear of the car to the front of the car as an example.
[0038] First, the beam drives the detector to run above the car to measure the body contour data. The program control system stores these values. According to the set cleaning distance requirements of each spray bar from the body surface, the program control system calculates the top spray bar, The movement position values ​​that the left and right vertical spray rods should reach. When the car washing machine moves from the rear of the car to the front of the car, the driving motor drags the beam to move forward as a whole. At different body positions, press the corresponding The control of the body contour of the vehicle requires motion instructions, and the corresponding motors drive the top spray bar, the left vertical spray bar, and the right vertical spray bar to reach the designated positions, so that the entire spray device and the upper part of the vehicle and the two sides of the body are Keep a reasonable distance, and working media such as high-pressure water and car wash fluid are sprayed to the body from the nozzle of each spray rod under the control of the program control system to achieve the ideal purpose of decontamination and cleaning of the vehicle.
[0039] Because the effective distance between each spray rod and the car body is controlled within a reasonable range, the spraying effect is more ideal. Take the movement of the beam from the middle of the car body to the front of the car as an example. The height of the car body gradually decreases with the windshield and engine cover. The spray bar also gradually drops, and the entire spray device realizes close-range motion control, which greatly improves the cleaning effect.
[0040] In the above embodiments, if the liquid working medium is changed to compressed air and the water spray head is changed to an air spray head, the spray device is an air drying device, and the corresponding body contour detection and the control and working modes of each movement mechanism are completely the same.
[0041] The program control system for motors, sensors and motion control adopted by the present invention is a mature and well-known technology, and will not be described in detail here.
[0042] In addition, the differences of the following various solutions (including but not limited to the following situations) are all within the intention of the present invention:
[0043] 1) The driving motors of the top spray bar, left vertical spray bar and right vertical spray bar adopt servo motors;
[0044] 2) The driving motor of the beam adopts stepping motor or servo motor;
[0045] 3) There can also be multiple top spray bars, left vertical spray bars, and right vertical spray bars.
[0046] The invention addresses the scientific requirements of high-pressure water cleaning for the working distance and solves the problem of measuring the height of the vehicle body. On this basis, the top spray bar that can be independently raised and lowered is adopted, which greatly enhances the cleaning effect on the top of the car and also makes the spray bar device The function for air drying becomes practical. At the same time, the left and right vertical spraying rods are used, and there is no need to run around when cleaning the car, but just go back and forth directly, so that the cleaning time is doubled, the function is stronger and more complete, and it has excellent working performance. After actual application of the device, the effect is very satisfactory. The applicant decided to mass produce it to provide a good car wash service for the current surge of cars.
