Description

Technical Field

[0001] The utility model belongs to the technical field of car washing robots, and in particular relates to a bus washing robot. Background Art

[0002] Buses are the main carrier of urban transportation operations. The cleanliness of the vehicle surface represents the appearance of a city. Generally, bus stations will conduct timely surface cleaning of vehicles that enter the station for a short stay every day to ensure that the vehicles in daily operation are in a clean state.

[0003] Most of the traditional bus cleaning modes still use manual cleaning, that is, manual wiping with a long mop dipped in water. However, due to the high body of the bus, this traditional handheld mop cleaning method is time-consuming and labor-intensive, with poor cleaning effect and extremely low car washing efficiency.

[0004] The existing alternative to manual mopping is a manually-towed mobile cleaning machine, which has wheels installed under the chassis and a certain type of cleaning roller brush installed on the upper part of the chassis. The entire cleaning machine is manually towed and controlled to move and turn around the bus to clean the outer skin. Although this method has changed the traditional mode of manual direct wiping, it still requires full human participation, and during the cleaning process, water mist will splash onto the operator, resulting in a poor working environment.

[0005] With the decline of the demographic dividend, it has become difficult to hire workers for some jobs with poor working environment and repetitive labor-intensive jobs. Therefore, the demand for intelligent and unmanned bus cleaning equipment that can completely replace manual labor is extremely urgent. Currently, there are two types of patents that have been published: fixed gantry automatic cleaning machines and self-propelled car washing machines, but both have major disadvantages and limitations. Although the fixed gantry type automatic washing machine can realize the whole process of automatic washing, it occupies a huge area, especially for buses with longer and wider bodies. Compared with family cars, the gantry type washing machine requires a larger area, which is particularly unsuitable for bus stops with relatively compact area. In addition, the gantry type automatic washing machine consumes a large amount of water and requires a wastewater collection system. The installation and construction of the overall equipment are relatively complicated, so it is rarely used in the bus washing industry. For the self-propelled car washing machines currently disclosed, their function is only to complete the walking around the vehicle according to the set program. Their structural design is to rely solely on the distance measuring sensor to maintain the distance from the vehicle body during the walking process. Due to the limitations of their structure, the unmanned and autonomous operation of the overall device cannot be fully realized, and they must be manually pulled to the designated position to realize semi-automatic operation.

[0006] There are still no related products in the industry for intelligent bus cleaning equipment that occupies a small area, has a compact structure, and can be fully unmanned. Since bus stops are outdoors and the bus stops are random, and the automatic cleaning process is difficult due to the different protruding positions and distances of the rearview mirrors of different models, there are a series of problems such as the difficulty of automatic avoidance. Therefore, the development of unmanned bus cleaning equipment combined with this complex application scenario has certain technical development difficulties. Utility Model Content

[0079] The automatic water collection and drainage component 12 plays a vital role in the bus washing robot. Its practicality and efficiency are fully reflected in the actual application scenarios, as follows:

[0080] The automatic water inlet 1201 is installed on the car body cover 3 and can automatically connect to the water supply system to achieve rapid water collection. This design not only saves the tedious steps of manual water collection, but also greatly improves the accuracy and efficiency of water collection. Before the car wash operation begins, the automatic water inlet can quickly replenish the required amount of water for the holding box to ensure that the car wash process is continuous and uninterrupted.

[0081] The water guide 1202 is connected to the water pipe, which ingeniously guides water into the holding box and is used to buffer the water flow during the automatic water addition process. This design effectively avoids the waste and splashing of water resources, ensuring the cleanliness and safety of the car washing site. At the same time, the smooth design of the water guide also ensures the smooth flow of water, improving the efficiency of the overall car washing operation.

[0082] The automatic drain port 1203 at the bottom of the chassis frame 103 is responsible for automatically draining the used water after the car wash is completed. This design not only prevents the accumulation of sewage inside the machine, but also effectively avoids the pollution of the environment by sewage. The efficient drainage capacity of the automatic drain port ensures that the car wash robot can complete the drainage operation in a short time and prepare for the next car wash operation.

[0083] In summary, the automatic water receiving and drainage component 12 realizes the functions of automatic water receiving, smooth water guiding and efficient water drainage through the synergistic effect of the automatic water inlet, the water guide groove and the automatic drainage outlet. In actual application scenarios, these designs greatly improve the working efficiency and user experience of the car washing robot, and also help protect the environment and save water resources.

[0084] Further preferably, the opening and closing of the automatic water inlet 1201 is a mechanical spring structure, and the opening and closing of the automatic drain outlet 1203 is controlled by an electrical signal.

[0085] The design of the automatic water inlet 1201 and the automatic drain outlet 1203 demonstrates excellent practicality and convenience in the bus washing robot, as follows:

[0086] The automatic water inlet 1201 uses a mechanical spring structure to control opening and closing. This design has shown high reliability and stability in practical applications. When water is needed, the water inlet automatically opens through the spring mechanism and connects to the water source to achieve fast and automatic water supply. This mechanical operation reduces the use of electronic components, thereby reducing the failure rate and enhancing the durability of the equipment. After the car washing operation is completed, the water inlet will automatically close to prevent the waste of water and the entry of external impurities.

[0087] At the same time, the opening and closing of the automatic drain 1203 is controlled by electrical signals, showing a high degree of intelligence and flexibility. When the car wash operation is completed, the control system will send an electrical signal to command the drain to open and quickly drain the used water. This design not only ensures the timeliness of drainage, but also effectively prevents sewage from staying inside the robot for a long time, reducing the risk of bacterial growth and equipment corrosion. The accuracy of electrical signal control also ensures that the drain is accurately opened and closed when needed, further improving the efficiency and safety of the car wash operation.

[0088] In summary, in actual application scenarios, the mechanical spring structure of the automatic water inlet 1201 and the electrical signal control design of the automatic drain outlet 1203 together provide a stable and intelligent water resource management service for the bus washing robot.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
