Description

A water-conducting structure on the back of a frame strip for an automobile

technical field

The present application relates to the technical field of water guide for automobile frame strips, and specifically discloses a water guide structure for the back of a frame strip for automobiles.

Background technique

At present, the doors of many models on the market are frameless doors. Although the frameless doors are beautiful, most of the frameless doors have a gap when the front door glass is matched with the sealing strip due to the large difference between the door glass and the inner triangular decorative panel. As a result, the problem of poor waterproof effect is caused, and rainwater often enters the cab when driving in rainy days;

The existing door frame strips for automobiles are mostly used to connect the sheet metal position of the car door, which is used for waterproofing and sealing and sound insulation. However, when the door frame strips and the frameless glass are installed, there is a problem of matching errors, which will occur as shown in Figure 3. The problem shown is that the water will flow down along the door frame strip in rainy days or when washing the car. When the water leakage in Figure 3 occurs, the leaked water will continue to flow down to the corner position of the door frame strip, and then follow the corner position of the door frame strip. Entering the car, this is the pain point of the frameless door;

Most of the gajin in the current technology is to reduce the gap between the door frame strip and the glass to achieve waterproofing. This method is not desirable and cannot be a fundamental problem. Therefore, the present invention provides a new solution. The water guide channels at the corners guide the water to the outside of the vehicle to prevent water from entering the vehicle. In view of this, the inventor proposes a water guide structure for the back of a frame strip for an automobile.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the problem that the traditional frameless door leaks water and the water flows into the vehicle.

In order to achieve the above object, the present invention provides the following basic scheme:

The utility model relates to a water-conducting structure on the back of a frame strip for an automobile, comprising an automobile door frame, including a door frame strip used in cooperation with the automobile door frame, a sealing strip used for sealing against dust and water and used in conjunction with the door frame strip, and the sealing strip is arranged inside the door frame strip. The door frame strip corner is arranged under the car door frame, the door frame strip corner is arranged on the back of the car door frame, the back of the door frame strip is provided with a water guide channel, and the water guide channel communicates with the door frame strip corner.

The principle and effect of this basic scheme are as follows:

1. Compared with the prior art, the water will flow down along the door frame strip in rainy days or when washing the car. When the water leakage as shown in Figure 3 occurs, the leaked water will flow to the corner of the door frame strip. The water guide channel at the corner guides the water to the outside of the car, preventing water from entering the car, and finally solves the problem of water leakage from the traditional frameless door and water flowing into the car.

Further, the angle of the door frame strip is inclined.

Further, the inclined surface of the corner of the door frame strip and the water guiding channel are the same continuous surface.

Detailed ways

In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific embodiments, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

Reference numerals in the accompanying drawings include: automobile door frame 1 , sheet metal part 2 , door frame strip 3 , sealing strip 4 , water flow line 5 , door frame strip corner 6 , water guide channel 7 , inclined surface 8 .

Examples are shown in Figure 1, Figure 2, Figure 3 and Figure 4:

A water-conducting structure for the back of a frame strip for an automobile, comprising an automobile door frame 1, a door frame strip 3 used in cooperation with the automobile door frame 1, a sealing strip 4 used for sealing against dust and water and used in conjunction with the door frame strip 3, and a sealing strip 4 A door frame strip corner 6 arranged inside the door frame strip 3 and below the automobile door frame 1, the door frame strip joint corner 6 is arranged on the back of the automobile door frame 1, the back of the door frame strip 3 is provided with a water guide channel 7, and the water guide channel 7 and The door frame strip connecting corner 6 is connected.

Specifically: As shown in Figure 1, the car has a car door frame 1, and the A, B and C pillars are used to connect the car door frame 1, and then the door frame strip 3 is used to install it on the car door frame 1. When the car door is closed or the window glass is rolled up , the sealing strip 4 inside the door frame strip 3 can achieve the function of dustproof and waterproof in conjunction with the car door or window, but this form can only be used for framed doors, for frameless doors, such as sports cars, some cars, windows There is no door frame on it, so there is a phenomenon of water leakage;

For this, the water leakage situation is discussed first in this embodiment. When the window is closed, water enters the door frame strip 3 along the glass position due to the lack of a frame, and the prior art installation of the door frame strip 3 is to cooperate with the sealing strip 4, and the door frame strip 3 and the There is a gap between the sealing strips 4, which is an installation defect and cannot be avoided. The water flow at this time is as shown in 2. It flows from the front of the sealing strip 4 to the back of the sealing strip 4 along the sheet metal part 2 and the above gap. Due to the influence of gravitational potential energy, the water flow will always move downward;

Next, if no improvement is made, the water flow will inevitably flow into the car, affecting the performance of the car. Therefore, in this embodiment, a water guiding channel 7 is provided on the back of the door frame strip 3, and this water guiding channel 7 is just in the direction of the water flow. And the water guide channel 7 is arranged on the back of the door frame strip 3, which will not affect the appearance of the door frame strip 3;

The water flow continues to move downward along the above-mentioned water guide channel 7, and a door frame strip connection angle 6 is provided below the automobile door frame 1, and the door frame strip connection angle 6 is inclined. On the same continuous surface, the door frame strip corners 6 are used to connect the car door frame 1. In the prior art, the door frame strip corners 6 are at a certain distance from the interior of the car. When the water leakage as shown in Figure 3 occurs, The leaked water will flow to the corner 6 of the door frame, and the inclined surface 8 at the corner will cooperate with the water guide channel 7 to guide the water to the outside of the car to prevent water from entering the car.

The device solves the problem that the traditional frameless car door leaks water and then the water flows into the car.

The above descriptions are only preferred embodiments of the present invention, and do not limit the present invention in any form. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art , without departing from the scope of the technical solution of the present invention, when the technical content disclosed above can be used to make some changes or modifications to equivalent embodiments of equivalent changes, as long as it does not depart from the technical solution content of the present invention, according to the technical solution of the present invention Substantially any brief modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the technical solutions of the present invention.
