Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
The invention is described in further detail below with reference to the figures and the specific embodiments.
The application relates to a hood decoration piece drainage system, and the drainage system of the application is applied to an engine hood. As shown in fig. 1 to 6, an outer garnish 1, a hood outer panel 2, a hood inner panel 3, and an inner garnish 4 are attached to an engine hood in this order from top to bottom, the outer garnish 1 is attached to an upper end surface of the hood outer panel 2, an attachment groove is provided in an upper end surface of the hood outer panel 2, the outer garnish 1 is fixed in the attachment groove, the hood inner panel 3 is attached to a lower end surface of the hood outer panel 2, and the inner garnish 4 is attached to a lower end surface of the hood inner panel 3.
A hollow chamber exists between the exterior trim 1 and the hood outer panel 2, and water is accumulated in the hollow chamber during rain or washing, so that the accumulated water needs to be actively discharged. In order to discharge the ponding in the cavity, wash port 5 has been seted up at the lowest of the mounting groove of aircraft bonnet planking 2 to this application, as shown in fig. 2, wash port 5 of this application has two, arranges to the interval along Y, and wash port 5 is located mounting groove along X to the front end position, because aircraft bonnet planking 2 belongs to the high structure in low back before, consequently sets up like this and can ensure that ponding is whole to be discharged through wash port 5.
The flow channel is arranged on the hood inner plate 3 and the inner decoration 4, the water inlet end of the flow channel is communicated with the drain hole 5, and the water outlet end of the flow channel is positioned in the gap of the engine room. The runner is used for accepting wash port 5 for the position drainage established with the leading-in cabin of wash port 5 discharged water, the position of establishing said in this application indicates the clearance position of cabin, mainly indicates the region between preceding guarantor and the cabin radiator, and the interface of pencil has been avoided in this regional drainage, and water directly discharges on the front bumper, can not cause the damage to important components and parts in the cabin.
In addition, in order to actively control the drainage, a drainage valve 10 is disposed at the position of the drainage hole 5, and as shown in fig. 1, the drainage valve 10 is used for controlling the opening or closing of the drainage hole 5. When the drainage valve 10 is opened, the drainage hole 5 actively drains water, and when the drainage valve 10 is closed, the drainage hole 5 cannot drain water downwards.
In order to control the drain valve 10, vehicle state parameters, hood lock states and environmental information are combined, the drain valve 10 is controlled by acquiring the parameters, and the problem of damage caused by water inflow of important components of an engine room due to the fact that drain holes 5 drain water when the condition is not allowed is avoided.
The drainage system comprises a hood lock state acquisition module, a vehicle state acquisition module, a rainfall monitoring module and a control module, wherein the hood lock state acquisition module is used for acquiring whether a hood lock is in a locked state or an unlocked state; the vehicle state acquisition module is used for acquiring the running parameters of the vehicle; the rainfall monitoring module is used for judging whether the current vehicle is in the rainy environment; the control module is used for receiving parameters acquired by the hood lock state acquisition module, the vehicle state acquisition module and the rainfall monitoring module and controlling the drain valve based on the parameters.
The engine hood lock state acquisition module acquires the state of the engine hood lock, and if the engine hood lock is in an unlocking state, the engine hood is opened at the moment, and the engine hood is likely to cause the water inflow of important components of the engine cabin through water drainage at the moment. Since the hood is in an open state in connection with maintenance, inspection, or the like, it is necessary to take the above-described situation into consideration when controlling the drain valve.
The vehicle state acquisition module is used for acquiring vehicle operation parameters, judging whether the current state of the vehicle meets the requirement of water drainage or not according to the vehicle operation parameters, controlling the water drainage valve to be closed if the current state of the vehicle does not meet the requirement, and opening the water drainage valve to drain water or ventilate if the current state of the vehicle meets the requirement.
