Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of car washers, in particular to a safety device mechanism for a car washer. Background Art
[0002] With the development of the times, car washing machines have gradually replaced manual cleaning and are gradually popularized and used by the public.
[0003] One type of contactless car washing machine is widely applicable to the vehicles being washed. The vehicle being washed is parked in the car washing area, and the car washing machine moves back and forth along the direction of the vehicle's movement. The high pressure is raised and lowered according to the height and shape of the vehicle, and the car is washed by simulated scanning to ensure that the high-pressure water of the car washing machine maintains a constant distance from the vehicle being washed and a constant impact force, so as to effectively wash away and dissolve the dust and dirt on the vehicle's surface.
[0004] The general process of contactless car washing machine is as follows: the first step is to spray the car washing solution on the surface of the vehicle to be washed, and dissolve it for a certain period of time to loosen the dirt on the surface of the vehicle, decompose the protein, and remove the static dust. The second step is to use high-pressure water to spray at high pressure to remove the dirt on the surface of the vehicle to be washed. The third step is to spray car wax water. The fourth step is to use a high-pressure fan to dry the car to gradually blow away the water droplets and car washing liquid on the surface, thus completing the car washing.
[0005] Car washers are usually equipped with safety devices for anti-collision warnings. The safety devices in the car wash machine structure often make misjudgments, resulting in scratches or bumps between the car wash machine and the washed vehicle. The installation devices are not suitable for certain special models, luggage racks or roof luggage boxes, and some rear tires. Due to their different shapes, the safety devices bypass these design areas or touch the installation devices. The car wash machine cannot perform the protection shutdown and continues the car washing operation, causing damage to the vehicle.
[0006] like Figure 6 As shown, an existing safety device is shown. The mounting device 1 is designed as a rectangular parallelepiped shape, which is formed by bending and welding. A guide rod 2 is welded to the bottom of the mounting device 1. The safety ring 5 is processed and then bent into a U shape. The two ends are machined with threads. The safety frame 4 is also machined and connected to the end of the safety ring 5 as a whole. The proximity switch 3 is mounted on the two side walls of the mounting device 1. When the washed vehicle passes the photoelectric code scanning model for appearance cleaning, the lifting and rotating high-pressure water is raised and lowered according to the height of the model. However, when there is a large gap in the middle, the safety ring is needed to assist in judging the appearance of the model, so that the car wash has more safety guarantees. However, due to the safety structure shape, it is too closed, too complicated, and not sensitive, resulting in frequent car wash failures. Because it is too closed, it is difficult to repair after sales. Utility Model Content
