Description

Technical Field

[0001] The utility model relates to the field of vehicle body parts, in particular to a one-way sealing structure of a front cabin water flow channel. Background Art

[0002] The front cabin water trough is usually located at the bottom of the front windshield of the car, and is used to guide and drain rainwater, washing liquid, etc. flowing down from the front windshield. Due to the molding requirements of the water trough, the drainage ports at both ends have a U-shaped groove structure and cannot be sealed by the sealing strip, so that the odorous gas in the front cabin can enter the air inlet of the air conditioner through the water trough, and then enter the cab.

[0003] Some car models have added seals at the U-shaped groove. Although this has a sealing effect, it affects the drainage effect of the front cabin water trough. Utility Model Content

[0004] In order to solve the above technical problems existing in the front cabin water flow channel, the utility model provides a one-way sealing structure of the front cabin water flow channel.

[0005] The installation scheme of the one-way sealing structure of the front compartment water flow channel provided by the present application is as follows: the one-way sealing structure of the water flow channel includes a main body installation frame, a sealing gasket and a sponge strip for sealing. The installation frame is respectively installed on the front and rear flange surfaces of the front compartment water flow channel through buckles at both ends; the installation frame and the sealing gasket are connected by the sealing gasket clamp; the installation frame and the sponge strip are bonded by a rubber strip.

[0006] The sealing gasket is vertically connected to the nylon frame through claws, and the connection method is a movable connection.

[0007] The bottom of the installation frame is sealed with the bottom surface of the water trough by bonding the sponge strip.

[0008] The main body mounting frame is provided with mounting frame buckle 1 and mounting frame buckle 2, which are integrally formed; a mounting frame drainage outlet is provided in the middle of the mounting frame, and mounting frame limiting ribs are provided around the drainage outlet.

[0009] Preferably, the nylon frame is evenly distributed with reinforcing ribs to improve its own strength.

[0010] Preferably, a circle of limiting ribs is provided at the joint of the nylon frame and the sealing gasket to prevent the sealing gasket from entering the inner side of the drain port. When water flows out of the water trough to the drain port, the sealing gasket opens outward under the action of the water flow, allowing the water to flow out smoothly. The connection between the sealing gasket catch and the mounting frame is a movable connection, and the sealing gasket can only be opened and closed on the outer side of the limiting ribs of the mounting frame.

[0011] Under the action of gravity, the sealing gasket will cover the limiting ribs on the outside of the nylon frame drain outlet when it is stationary, preventing external gas from entering the water flow channel.

[0012] By adopting the above technical solution, the one-way sealing structure of the water flow trough is simple and easy to install. While playing the role of gas sealing, it will not affect the drainage function of the water flow trough. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present application is further described in detail below in conjunction with the accompanying drawings.

[0017] This application implements a one-way sealing structure for the front cabin water tank, referring to Figure 1 The one-way sealing structure of the water flow channel comprises a main body installation frame (1) and a sealing gasket (2) for sealing. The installation frame (1) and the sealing gasket (2) are connected by a sealing gasket clamp (21), the sealing gasket (2) and the sealing gasket clamp (21) are integrally formed, and the connection between the sealing gasket clamp (21) and the installation frame (1) is a movable connection, so that the sealing gasket (2) can be opened along the direction of the drainage port (15) of the installation frame, but cannot be rotated.

[0018] Reference Figure 2 When installing the mounting frame (1), first install the sealing gasket clamp (21) in the clamp installation hole (16) of the frame, then adhere the sponge strip (4) to the bottom sealing surfaces (17) and (18), and finally install the mounting frame buckles (11) and (12) on the front and rear flange surfaces of the front cabin water flow channel (4), thereby achieving stability and sealing of the mounting frame (1).

[0019] Reference Figure 2 The sealing pad (2) is arranged at an angle. Under the action of gravity, the sealing pad will cover the outside of the nylon frame drain port when it is closed, thereby preventing the outside gas from entering the water flow trough.

[0020] Reference Figure 3A circle of limiting ribs (13) is provided on the mating surfaces of the mounting frame (1) and the sealing gasket (2) to prevent the sealing gasket from entering the inner side of the drain port. When water flows out of the water trough to the drain port, the sealing gasket opens outward under the action of the water flow, allowing the water to flow out normally. When there is no water flow, the sealing gasket (2) returns to a closed state to prevent external gas from entering.

[0021] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
