Description

Technical Field

[0001] The invention relates to the technical field of waterproofing of a wiper cover, and in particular to a waterproofing structure of a wiper cover. Background Art

[0002] With the rapid development of the automobile industry, the drainage system on the car has been continuously improved. The wiper cover is an automobile part arranged between the front windshield and the rear of the engine hood. The wiper cover is provided with an air-conditioning air inlet grille, which can also be used to drain rainwater into the drainage system. At present, the area below the air-conditioning air inlet grille of the wiper cover is the air inlet of the air-conditioning compressor, so it is necessary to ensure that the air inlet is dry and cannot be wet by rain. A water guide plate is generally provided at the bottom of the air-conditioning air inlet grille to prevent rainwater from entering the air inlet. However, the waterproof effect of the fixed point between the water guide plate and the wiper cover is poor, which makes it easy for water to leak into the air inlet of the air conditioner. Summary of the invention

[0003] The main purpose of the present invention is to provide a waterproof structure for a wiper cover to solve the problem that the current fixing point between a water guide plate and the wiper cover has a poor waterproof effect, which easily leads to water leakage into the air inlet of the air conditioner.

[0004] A waterproof structure of a wiper cover, comprising a wiper cover, a front windshield and a water guide plate, wherein the front windshield is arranged at the rear end of the wiper cover, an air-conditioning air inlet grille is arranged on the left side of the upper end of the wiper cover, the water guide plate is fixed to the left side of the lower end of the wiper cover, a welding pipe is fixed to the lower end of the wiper cover, a water retaining rib is fixed to the lower end of the wiper cover and located outside the welding pipe, the bottom of the water retaining rib is in contact with the top of the water guide plate, a fixing hole is arranged at the upper part of the water guide plate, the lower end of the welding pipe is inserted into the fixing hole and welded to the water guide plate, and a water retaining boss is fixed to the upper part of the water guide plate and located outside the fixing hole.

[0005] Furthermore, the water guide plate is located directly below the air inlet grille of the air conditioner, and the water guiding direction of the water guide plate is toward the drainage system of the automobile.

[0006] Furthermore, a rubber ring is provided between the outer wall of the welded pipe and the inside of the water retaining rib, and the top of the water retaining boss abuts against the bottom of the rubber ring.

[0007] Furthermore, a fixing hole extends from the lower end of the welding pipe, a threaded pipe is fixed to the lower end of the welding pipe, and a nut is threadedly connected to the outer wall of the threaded pipe.

[0008] Furthermore, a sealing gasket is provided on the outer side of the upper end of the nut, and the top of the sealing gasket is in contact with the water guide plate.

[0009] Furthermore, a convex ring is fixed on the upper side of the outer side of the threaded tube, which is integral with it. The convex ring is located at the lower end of the welding tube and fixed to the welding tube. An annular groove is provided on the upper end of the nut and inside the sealing gasket, and the convex ring is plugged into the annular groove.

[0010] Furthermore, an outer rubber layer is provided on the surface of the convex ring, an inner rubber layer is provided on the inner wall of the annular groove, and the outer rubber layer is located inside the inner rubber layer and is in contact with the inner rubber layer.

[0011] Beneficial effect: when the water guide plate is fixed under the wiper cover, the fixing hole of the fixing point is passed through by the welding tube, and the welding tube is welded to the water guide plate. After the water guide plate is fixed, the water retaining rib will be in close contact with the water guide plate, which plays a role of the first layer of waterproofing. At the same time, the water retaining boss on the fixing hole will be in close contact with the rubber ring on the inner side of the water retaining rib, which plays a role of the second layer of waterproofing. The welding tube is inserted into the fixing hole and welded to the water guide plate, which plays a role of the third layer of waterproofing. Therefore, after being fixed, the three layers of waterproofing of the fixed point are played, which improves the waterproofing effect. In addition, after being fixed, the nut can be turned to the outside of the threaded tube to reinforce the water guide plate. At the same time, the sealing gasket is closely attached to the bottom of the water guide plate, which can play a role of the first layer of waterproofing. At the same time, the convex ring will be inserted into the inside of the annular groove to play a role of the second layer of waterproofing. In this way, the three layers of waterproofing are arranged above the fixing point of the water guide plate, and the two layers of waterproofing are arranged below, which further improves the waterproofing effect. The sealing gasket arranged below, the outer rubber layer of the outer wall of the convex ring, and the inner rubber layer of the inner wall of the annular groove can increase the friction when the nut is turned out, so as to play a role of preventing the nut from loosening.
