Description

Technical Field

[0001] This utility model relates to the technical field of bus air intake systems, specifically a water-blocking and air-guiding air intake structure applied to hybrid and fuel cell buses. Background Technology

[0002] like Figure 1 As shown, the front air intake of a traditional bus air intake assembly uses an open design, with the rear intake hose directly connected to the air filter system via a circular hole. This structure has a significant drawback:

[0003] 1. Insufficient waterproof performance: When driving in heavy rain or through water, rainwater can easily enter the air intake box directly from the front opening and seep into the air intake system through the rear round hole, causing the air filter to become damp, the engine power to decrease, and even causing safety hazards such as short circuits.

[0004] 2. Insufficient ability to prevent solid impurities: Dust and impurities raised during operation can enter the system with the airflow, accelerating filter clogging and increasing maintenance frequency.

[0005] 3. Poor structural stability: No dedicated support for fixing the pipes is installed, and the wiring harness and pipes are prone to displacement due to vibration, affecting the reliability of the system. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a water-blocking, air-guiding, and air-intake structure.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is to provide a water-blocking, air-guiding, and air-intake structure, including:

[0008] The frame provides overall structural support and positioning reference, including the cable board positioning part and the air intake box positioning part; the cable board is fixed to the cable board positioning part of the frame;

[0009] Connect the bracket and fix it to the bottom of the cable board positioning part of the cable board and the frame to fix the air intake shroud assembly to the hydrogen stack mounting bracket.

[0010] The air intake box is located on one side of the wiring board and fixed to the air intake box positioning part of the frame. The front air intake of the air intake box is equipped with multiple Z-shaped water-blocking grilles, and the rear round hole connects to the air intake hose to achieve air diversion, filtration and waterproofing. The drip sleeve is located at the bottom of the air intake box and has a built-in lip valve. It diverts the liquid that has entered the cavity to the outside of the vehicle through the principle of gravity self-drainage.

[0011] The wiring harness bracket is fixedly installed on the side of the air intake box to achieve independent fixation of the pipes and wiring harnesses, avoiding interference.

[0012] According to this utility model, the Z-shaped water-blocking grilles are equidistantly distributed at the front air inlet of the air intake box.

[0013] According to this utility model, the Z-shaped water-blocking grille further includes two parallel first connecting parts and a second connecting part connecting the two first connecting parts, and the two first connecting parts are respectively connected to the peripheral wall of the front air inlet of the air inlet box on the corresponding side.

[0014] According to this utility model, each of the Z-shaped water-blocking grilles is arranged at an inclination angle of 30° to form a water-blocking and wind-guiding barrier.

[0015] According to this utility model, the distance between two adjacent Z-shaped water-blocking grilles is ≤7mm.

[0016] According to this utility model, the included angle between the second connecting portion and the first connecting portion on the corresponding side is 53°-58°.

[0017] According to this utility model, the angle between the second connecting portion and the first connecting portion on the corresponding side is 55°.

[0020] According to this utility model, the material of the skeleton is Q235, and the wall thickness is 1.5mm.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The addition of a Z-shaped water-blocking grille to the front air intake can greatly prevent rainwater from directly entering the air intake hood through the front air intake, thereby reducing the possibility of water and impurities entering the air intake system and significantly improving the waterproof and impurity-proof performance as well as the overall structural strength.

[0023] The components of this invention are modularly designed for rapid assembly, and the Z-shaped grilles are arranged at a 30° angle to form a water-blocking and wind-guiding barrier, effectively improving waterproof and impurity-proof performance.

[0024] The Z-shaped water-blocking grille, combined with the drip sleeve, forms a two-way waterproof system. Through the Z-shaped water-blocking grille structure and reasonable spacing, it can block more than 90% of rainwater from entering from both the front and rear, and then drain it out of the vehicle through the drip sleeve.

[0025] This invention is applicable to various new energy vehicle models such as fuel cells and hybrid vehicles, and has a wide range of applications. Attached Figure Description
