Technical Field

The utility model relates to the field of automobile auxiliary equipment, in particular to a power tank with coexistence of high-pressure water and gas and a cleaning system.

Background

The acquisition sensor is one of the core components of the automatic driving technology of the automobile, and the existing acquisition sensors such as a radar and a camera are the second eyes during automatic driving. In order to accurately and unimpededly acquire road information, acquisition sensors such as radars and cameras need to be arranged outside a vehicle body. Acquisition sensors that are exposed to the environment for extended periods of time are susceptible to various unpredictable environmental effects such as rain, dust, resins, bird droppings, and the like. Although these do not necessarily really damage the interior of the acquisition sensor, they often present a detection obstacle to the acquisition sensor due to their adhesion to the surface of the acquisition sensor, and in severe cases even lead to failure of the acquisition sensor or to false positives, which have a non-negligible effect on the automatic driving system.

The prior art typically adds an on-board cleaning system to a vehicle having an external acquisition sensor. On-vehicle cleaning system comprises water tank, water pump and pipeline usually, sets up on-vehicle cleaning system and helps carrying out surface cleaning to acquisition sensor at any time to thereby ensure that its surface does not have the accuracy of guaranteeing to detect. However, the existing common vehicle is not provided with a water pump meeting the requirement of cleaning, and when a vehicle-mounted cleaning system is additionally arranged, the water pump needs to be additionally configured. This results in the water pump in the vehicle wash system being idle most of the time, with low utilization, except for occasional washes; on the other hand, the water pump and the water tank are added, so that the volume of the cleaning system occupies a large space, and a part of small vehicles cannot be installed; moreover, the starting of the water pump has certain time delay, so that water is slowly discharged during cleaning, and the operation is not friendly enough; but also adds to the complexity of the vehicle control circuitry and power circuitry. A new technology is needed for solving the problems of low water pump utilization rate, large occupied space of a vehicle-mounted cleaning system, unfriendly operation and increased design complexity of a vehicle control circuit and a power supply circuit when liquid is supplied through a water pump.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome at least one defect (deficiency) of the prior art, and provides a high-pressure water-gas coexisting power tank and a cleaning system, which are used for solving the problems that the utilization rate of a water pump is low, a vehicle-mounted cleaning system occupies a large space, the operation is not friendly, and the design complexity of a vehicle control circuit and a power supply circuit is increased when liquid is supplied through the water pump.

The utility model adopts the technical scheme that a power tank with coexisting high-pressure water and gas comprises: container subject, with inside inlet, the liquid outlet and the air inlet of intercommunication of container subject, container subject includes: a gas containment zone for containing a gas under pressure; a liquid containing region for containing a liquid; the gas inlet is used for injecting compressed gas; the gas pressure of the gas containing area is greater than the pressure of the liquid outlet. In the technical scheme, the container body is a container capable of being sealed and resisting pressure; the liquid inlet is used for adding liquid required by cleaning into the container main body, and the liquid outlet is used for discharging the liquid in the container main body during cleaning. The liquid inlet and the air inlet can be combined into an access port. The container body is divided into a gas containing area located at an upper portion and a liquid containing area located at a lower portion of the gas containing area. The gas stored in the gas containing area is compressed gas with pressure, and the compressed gas can be injected at one time in a pre-stored mode and is sealed in the container main body. Compressed air can enter the liquid containing region to exert pressure on the liquid in the liquid containing region. When the liquid outlet of the communicating liquid containing area is communicated with the outside, the liquid covering the liquid outlet can be continuously pressed out of the container main body under the action of compressed gas until the pressure in the containing main body is consistent with the pressure of the liquid outlet. The pressure of the liquid outlet is not only from air, but also from other external equipment to apply the pressure to the liquid outlet.

The compressed gas is arranged in the container main body, and the gas pressure of the compressed gas acts on the liquid in the container main body, so that the power tank can drive the liquid in the power tank to be discharged without being externally connected with a liquid pump. The advantage of using gas pressure as power is that firstly, the structure and control of the cleaning system are simplified without using a liquid pump, and the failure rate is reduced to a certain extent; the liquid pump and the liquid pump power supply circuit occupy small volume, and the energy loss in the control and starting process and the maintenance cost from the liquid pump and the power supply and control of the liquid pump are reduced.

Preferably, the gas pressure container is arranged outside or inside the container main body; the gas pressure vessel is used to continuously deliver compressed gas into the gas-containing region. In the technical scheme, the gas pressure provided by the gas pressure container is not lower than the working pressure required by the gas containing area. Due to the fact that the external compressed air source is arranged, the requirement of the power tank on the volume of the air containing area and the required pre-filling air is reduced, and the difficulty of debugging before production and use is simplified. When the gas pressure container is arranged outside the container main body, the volume of the gas containing area can be greatly reduced because the container main body can be continuously supplemented by the compressed gas. As the design of disconnect-type, power jar and the putting of gas pressure vessel are more nimble. When the gas pressure container is arranged in the container body, the gas pressure container replaces the gas containing area, so that the gas containing area and the liquid containing area are separated, and only a connecting port for communicating the compressed air and the liquid containing area is reserved. This has the advantage of limiting the space available for compressed gas and liquid to move and reducing the unstable output that can be imparted during movement.

When the liquid outlet exposes, compressed gas can directly communicate with the liquid outlet to discharge through the liquid outlet. This reduces the liquid utilization of the power tank at low liquid levels and gives false indications of a complete lack of water. The flow limiting device can reduce the shaking and the transfer of liquid in the accelerating process, and does not obstruct the mutual communication between the liquid containing areas when limiting the liquid above the liquid outlet, thereby effectively reducing the exposed problem of the liquid outlet and ensuring that the liquid supply of the power tank is more stable.

In the technical scheme, the gathering surface is used for guiding the flowing of liquid, so that the liquid at different positions in the liquid accommodating area is quickly supplemented with the reduced liquid due to the discharge under the action of the gathering surface, and the continuity and the stability of the liquid outlet state of the power tank are ensured. Such a design is also advantageous in emptying the liquid containing area during use, avoiding problems caused by accumulation of residual liquid and reducing the limitation on the output pressure to a certain extent.

The liquid outlet is located a liquid cavity that hinders, and through the effect of current-limiting plate, liquid gathers at the liquid cavity that hinders that the liquid outlet is located to guarantee the stability of power jar output liquid. Furthermore, the flow limiting device enables the liquid blocking cavities to be communicated through the communicating opening and the communicating hole, so that liquid in different liquid blocking cavities in the container main body can flow to the liquid outlet.
