Automotive ventilation window

Abstract

The invention relates to an automotive ventilation window. A top cover (4) and a main frame part (9) are connected into a whole by using stainless iron screws to form a complete ventilation window, a push-pull device (15) and an opening device are respectively fixed at the front ends and the rear ends of the top cover (4) and an inner cover (1), a ventilation fan (14) is fixed at the center of a wind scooper (6), one end of the wind scooper (6) is connected with the top cover (4), the inner cover (1), an auxiliary frame (3) and a decorative sheet (2) are arranged at an inner ring of the main frame part (9), the rear end of the top cover (4) is provided with a rain cover (5), the wind scooper (6) is connected with the rain cover (5), and an air inlet is designed in hand clasping profiles (10). The automotive ventilation window is characterized in that a rain shielding rib I (7) and a rain shielding rib II (8) are arranged in the wind scooper (6) to form double waterproof effects in cooperation with the rain cover (5). The structure provided by the invention has the advantages of strong air exhaust, low noise, high airtightness, labor saving in opening and closing operation, and inward/outward bidirectional opening.

Description

technical field [0001] The invention belongs to the field of auto parts manufacturing, in particular to a ventilation window for passenger cars. Background technique [0002] According to market research, relevant data and chart analysis, there are the following problems in the use of the existing passenger car ventilation windows: 1. Water leakage: when the vehicle is driving at high speed in the rain, it will be affected by the air flow, and the rainwater will enter from the air outlet. The interior of the ventilation window causes water leakage from the ventilation window, which affects the quality and use of the vehicle; 2. Loud noise: the ventilation window has a problem of high noise, and the noise is greater than 68 decibels. 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 exhaust system inside the ventilation window; The exhaust port is ...

Problems solved by technology

[0002] According to market research, relevant data and chart analysis, there are the following problems in the use of the existing passenger car ventilation windows: 1. Water leakage: when the vehicle is driving at high speed in the rain, it will be affected by the air flow, and the rainwater will enter from the air outlet. The interior of the ventilation window causes water leakage from the ventilation window, which affects the quality and use of the vehicle; 2. Loud noise: the ventilation window has a problem of high noise, and the noise is greater than 68 decibels

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 exhaust system inside the ventilation window; The exhaust port is not reduced; in order to reduce noise, the speed of the ventilation fan motor will be reduced, and the reduction of the motor speed will result in a decrease in wind pressure

The above two reasons directly lead to insufficient ventilation of the ventilation window.

4. Opening and closing is laborious: the current common opening and closing method for ventilation windows is to apply force to the buckles on both sides of the inner cover. Due to the narrow space between the two sides of the inner cover and the main frame components, only the front of the finger can reach into the buckle In the hand, it is laborious to open and close

5. The outside cannot be opened: Most of the existing ventilation windows can only be opened from the inside of the vehicle. When a vehicle accident occurs, rescuers cannot open the ventilation windows from the outside to rescue
