Novel waterproof structure of vehicle-used safety roof window

Abstract

The invention relates to a novel waterproof structure of a vehicle-used safety roof window. The novel waterproof structure consists of a top cover (1), a motor bracket (2), a ventilating fan (3), a rain sheltering hood (4) and an inner cover (5), wherein the ventilating fan (3) is fixed in the motor bracket (2); the motor bracket (2) is fixed on the top cover (1); the rain sheltering hood (4) is fixed on the top cover (1); and the top cover (1) and the inner cover (5) are fixedly combined by sealant and screws. The novel waterproof structure is characterized in that an outer ring of the motor bracket (2) is provided with a flanging as a rain sheltering bar I; rain sheltering bars II are arranged on two sides of the rain sheltering hood(4); and an air opening of each exhausting outlet (4-1) faces just below. According to the novel waterproof structure disclosed by the invention, the top cover of the safety roof window adopts a split type structure, the exhausting outlets are formed in two sides and face just below, the middle part of the top cover adopts a vaulted structure, and the rain sheltering bars are arranged on the rain sheltering hood, so that exchanging and maintaining the motor bracket and the ventilating fan can be performed outside a vehicle.

Description

technical field [0001] The invention belongs to the manufacturing field of auto parts. The structure is applied to a safety windshield assembly, and the installation structure of the windshield ventilation fan and its ventilation channel structure are changed to achieve waterproof and return wind prevention. Background technique [0002] The safety windshield is one of the important parts of the car. All kinds of passenger cars in my country generally have a safety windshield on the top of the vehicle, which can be used as an emergency exit in an emergency and can increase the convection between the air inside the car and the outside air. However, the existing safety windshield for vehicles generally has the following problems in use: 1. Water leakage: when the vehicle is traveling at high speed in an environment with a large amount of rainfall, it will be affected by the air flow, and rainwater will enter the inside of the safety windshield through the air outlet. , resulti...

AI Technical Summary

Problems solved by technology

However, the existing safety windshields for vehicles generally have the following problems in use: 1. Water leakage: when the vehicle is traveling at high speed in an environment with a large amount of rainfall, it will be affected by the air flow, and rainwater will enter the inside of the safety windshield through the air outlet. , resulting in water leakage from the safety windshield, affecting the quality and use of the vehicle; 2. Air leakage: return air enters the interior of the compartment from the air inlet. The main reason for this phenomenon is that the position of the air outlet and the design of the ventilation channel are unreasonable; 3. Noise Large: There is a problem of high noise in the safety windshield

There are two main reasons for this phenomenon: one is the noise generated by the ventilation fan motor itself; the other is the noise generated by the unreasonable design of the internal ventilation channel
