Description

Water retaining structure for air inlet of automobile air conditioner

Technical Field

The invention relates to the field of automobile air conditioner accessories, in particular to a water retaining structure for an air inlet of an automobile air conditioner.

Background

In order to ensure the air-conditioning air inlet volume, the launder is provided with an air-conditioning air inlet, most of the launders (as shown in figure 1) of medium and high-end pick-up trucks in the current market adopt a vertical air inlet form, the air inlet is directly communicated with an air blower, a surrounding plate is welded on the periphery of the air-conditioning air inlet, the main function is to prevent flowing water in the launder from entering the air inlet, the surrounding plate is provided with a glue coating groove, and expansion glue is filled in the glue coating groove to ensure good sealing; the upper part of the water flowing groove is provided with front windshield glass and a front windshield decorating part, the front windshield glass is connected with the water flowing groove through glass cement, and the front windshield decorating part is clamped with the front windshield through a buckle; the front windshield glass is connected with the front windshield decorating part through a sealing strip. Although the air inlet design can meet the requirement of air inlet quantity to the maximum extent, when the air conditioner is opened and the external circulation is at the maximum gear, the water inlet condition of the air inlet of the air conditioner exists mostly. For this situation, the air inlet structure of most pickup trucks is added with an air inlet water baffle as shown in fig. 2 to prevent water from entering the air inlet. However, the existing water baffle is made of plastics, so that the installation is complex, the occupied area is large, and more materials are wasted. The development of a water retaining structure which is simple in structure, convenient to install and capable of saving materials is urgently needed.

CN206734209U discloses a novel automobile air conditioner water baffle which is reasonable in structural design, water on a front windshield glass is prevented from entering from a lower beam of the front windshield or being sucked into an HVAC (heating ventilation air conditioning) from the side, reasonable sealing sponge materials and compression amount are adopted for the water baffle, the water on the water baffle is prevented from flowing back into the HVAC body, and the blast motor ablation in the HVAC body or the water entering from a passenger compartment copilot is avoided; the novel electric heating furnace is simple in structure, low in cost, simple and convenient to mount and dismount, and convenient to replace and maintain in the later period. The sealing device comprises a main body baffle plate which is in a U-shaped groove, wherein the port of the main body baffle plate is arranged close to the water outlet of the water flowing groove, the main body baffle plate is arranged on a front windshield lower cross beam through a fastener, and compressed sealing sponge is arranged between the main body baffle plate and the front windshield lower cross beam.

Also, for example, CN207579520U discloses an air-conditioner air inlet water baffle assembly and an automobile, wherein the air-conditioner air inlet water baffle assembly comprises a front windshield cross beam, a gutter channel and an air-conditioner air inlet, a water baffle is arranged at the air-conditioner air inlet, wherein, the water baffle is fixedly connected with the flume, the water baffle and the air inlet of the air conditioner form an air inlet channel, the air inlet of the air inlet channel faces to the front windshield cross beam, the air inlet of the air conditioner can finish normal air inlet operation, the contact point of the air inlet channel and the flume is sealed, water in the flume can not enter from the joint of the water baffle and the flume, the height of the water baffle is far more than the height of the liquid level in the flume, the overflow height of the water flow under various working conditions can not exceed the upper edge of the water baffle, so that the water flow can not enter the passenger compartment through the air inlet of the air conditioner under various limit working conditions, and the liquid in the water flowing groove is limited to flow into the air inlet of the air conditioner. No doubt none of the above is a useful attempt in the art.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

3-4, the water retaining structure for the air inlet of the automobile air conditioner comprises a shroud plate 3 arranged at an air inlet 2, wherein an heightening part 8 is arranged at the upper part of the shroud plate 3, the heightening part 8 comprises a fixing plate 801 horizontally arranged and tightly attached to the top of the shroud plate 3, a threaded hole 803 is formed in the fixing plate 801, a positioning hole 4 is formed in the top of the shroud plate 3, the fixing plate 801 is in threaded connection with the shroud plate 3 through a bolt 9 and a nut 10, one side of the fixing plate 801 inclines upwards to form a heightening plate 802, and the highest part of the heightening plate 802 extends into the lower part of a front windshield.

Adopt and set up on 3 upper portions of bounding wall and increase 8, directly borrow the mounting hole of welding locating hole 4 as newly-increased piece of former bounding wall, need not arouse the design change of other parts, reduced development cost, adopt bolt 9 to connect, convenient operation, and it is lower to spare part precision requirement, reduced the assembly degree of difficulty, the part is the sheet metal component of 0.7mm thickness, satisfy spare part development lightweight requirement, than current breakwater 7's development greatly reduced whole car cost. The heightening part 8 is composed of a fixing plate 801 and a heightening plate 802, the heightening plate 802 is an extending plate of which the fixing plate 801 inclines upwards, and the heightening plate 802 is close to the lower part of the front windshield glass 5, so that rainwater left between the front windshield glass 5 and the front windshield decoration 6 is blocked by the heightening plate 802 and flows into the water flowing groove 1 along the heightening plate 802 immediately, and liquid accumulation cannot be formed in the heightening part 8 and enters the air inlet 2.

Furthermore, a reinforcing rib 804 is arranged between the fixing plate 801 and the heightening plate 802, and flanging structures 805 with a height of 3mm are arranged on two sides of the reinforcing rib. This results in an increase in the rigidity of the heightening member 8.

Further, the heightening piece 8 is made of a galvanized plate with a thickness of 0.7 mm. The part often contacts the rainwater, is high anticorrosive position, consequently adopts galvanized sheet to satisfy its corrosion protection, because it does not bear stress again, so adopt 0.7mm thickness panel, reduces spare part cost when reducing weight, realizes the lightweight design of product.

Further, an angle α between the fixed plate 801 and the heightened plate 802 is 100 ° to 120 °. Thus, the heightening plate 802 can contact the front windshield glass 5, and the gradient of the heightening plate 802 is large enough, so that rainwater can smoothly flow into the water flowing groove 1.

Further, the bolt 9 is a projection welding bolt. Projection welding is a high-efficiency welding method capable of simultaneously performing multiple spot welding, and can be used instead of arc welding, brazing, and bite welding. The method has the characteristics of high processing speed and no other consumption except electric power, and is a great characteristic. The difference between projection welding and spot welding is that a plate is provided with a projection in advance, or a profile, a chamfer, or the like, on which current can be concentrated, is used as a mutual contact portion during welding. The welding is carried out by the contact of the salient points, so that the pressure and the current density on a unit area are improved, the oxide film on the surface of the plate is favorably crushed, the heat is concentrated, the shunt is reduced, the center distance of spot welding is reduced, the multi-point projection welding can be carried out at one time, the production efficiency is improved, and the warping deformation of the joint is reduced. On the vehicle body, a projection welding nut (a nut with convex points) is generally welded on a thin plate, so that only the bolt 9 needs to be screwed during assembly, and the assembly efficiency is improved.
