Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to an adjustable load-bearing interior water cutter for a car door, a car door, and a car. Background Technology

[0002] The inner door water cutter is a rubber product installed on the inner door panel. It is mainly used to clamp the glass for sealing, and also has the functions of defrosting, dewatering and dust removal. When considering sealing performance, the greater the compressive load of the inner water cutter lip, the better. When considering the sound performance of glass lifting, the smaller the compressive load of the inner water cutter lip, the better. The compressive load of traditional inner water cutter lips is not adjustable, so it cannot take into account both of the above conditions. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides an adjustable load inner water cutter for car doors. The structure is simple, and the compressive load on the water cutter lip is adjustable. When considering sealing performance, the compressive load on the inner water cutter lip can be increased to enhance door sealing, reduce noise caused by poor sealing, and reduce rainwater leakage into the door. When considering smooth glass operation, the compressive load on the inner water cutter lip can be decreased to facilitate smooth and rapid glass operation and reduce friction noise during glass operation.

[0004] This invention proposes an adjustable load interior water cutter for vehicle doors, comprising a water cutter body and an interior door panel;

[0005] The water-cutting body is elastically snapped onto the upper part of the inner panel of the car door;

[0006] The water-cutting body is equipped with at least one set of adjustable load water-cutting lip components on the side corresponding to the car window glass. The water-cutting lip components are driven to press tightly against or separate from the car window glass by the forward and reverse rotation of the winch components, so as to enhance the sealing of the car door or facilitate the smooth and rapid lifting of the glass. The water-cutting body is also equipped with a corresponding number of winch components, which provide traction or thrust to the adjustable load water-cutting lip components, so that the water-cutting lip components can press tightly against or be adjacent to the car window glass.

[0007] At least one set of adjustable load water-cutting lip assemblies and a corresponding number of winch assemblies are rotatably connected, and at least one set of adjustable load water-cutting lip assemblies can be in contact with or adjacent to the vehicle window glass.

[0008] The adjustable load water-cutting lip assembly has a semi-circular arc structure in its cross section. It includes a water-cutting lip and a flexible support plate. One end of the flexible support plate is connected to the winch assembly, and the other end of the flexible support plate is set on the water-cutting lip. The winch assembly, which moves in both forward and reverse directions, drives the water-cutting lip to contract or expand through the flexible support plate.

[0009] The hoist assembly includes a rotating shaft and a forward and reverse motor. The side wall of the water shear body is provided with an open arc groove. Both ends of the rotating shaft are rotatably connected to the front and rear side walls corresponding to the open arc groove. One end of the rotating shaft penetrates the front side wall of the open arc groove and is connected to the forward and reverse motor for transmission.

[0010] The other end of the flexible support piece is fixed to the upper end of the water-cutting lip. The side wall of the water-cutting body is provided with an upward-opening arc groove. The rotating shaft is suspended on the upper part of the bottom wall of the upward-opening arc groove, and the two ends of the rotating shaft are rotatably connected to the front and rear side walls corresponding to the upward-opening arc groove. The initial position of the water-cutting lip is not in contact with the window glass, i.e., they are adjacent to each other. When considering the sealing performance of the window, the forward and reverse motor reverses to release the wound flexible support piece. The flexible support piece drives the water-cutting lip to move closer to the window glass and finally presses it against the window glass. The compressive load of the water-cutting lip can be adjusted to increase to enhance the door sealing performance, reduce wind noise caused by poor sealing performance, and reduce rainwater leakage into the door. When considering the smoothness of the glass lifting and lowering performance, the forward and reverse motor rotates forward to wind the flexible support piece. The flexible support piece drives the water-cutting lip to move away from the window glass and finally separates from and is adjacent to the window glass. The compressive load of the water-cutting lip can be adjusted to decrease to facilitate smooth and rapid glass lifting and lowering and reduce friction noise caused by glass lifting and lowering.

[0011] The water-cutting body has a downward-opening arc-shaped groove on its side wall, and an arc-shaped sliding track inside the water-cutting lip. The opening of the arc-shaped groove is connected to the arc-shaped sliding track. The other end of the flexible support piece can be telescopically slidably accommodated within the arc-shaped sliding track. The rotating shaft is suspended below the top wall of the downward-opening arc-shaped groove, and both ends of the rotating shaft are rotatably connected to the front and rear side walls corresponding to the downward-opening arc-shaped groove. The initial position of the water-cutting lip is not in contact with the car window glass, i.e., they are adjacent to each other. When considering the sealing performance of the car window, the forward and reverse motor rotates forward, releasing the wound flexible support piece. The flexible support piece moves forward along the arc-shaped sliding track inside the water-cutting lip to the end of the arc-shaped sliding track. The flexible support piece continues to move forward, driving the water-cutting lip towards the car window glass. As the water-cut lip approaches and ultimately presses against the window glass, its compressive load can be adjusted to increase, enhancing the door's sealing performance, reducing wind noise caused by poor sealing, and minimizing rainwater leakage into the door. When considering the smoothness of the window's operation, the forward and reverse motors reverse, winding the flexible support plate. The flexible support plate slides backward along the arc track inside the water-cut lip, retracting as it retracts. Once the flexible support plate retracts to a certain position, the outward pushing force on the water-cut lip is released, and the water-cut lip elastically retracts to its initial state. The water-cut lip then moves away from the window glass and eventually separates from it, becoming approximately touching it. The compressive load on the water-cut lip can be adjusted to decrease, facilitating smooth and rapid window operation and reducing friction noise during window operation.

[0012] The outer arc sidewall of the water-cut lip is provided with several semi-circular grooves, and a rotating roller is rotatably connected in each semi-circular groove. The rotating roller is made of rubber or felt. The function of the rotating roller is to increase the contact area between the water-cut lip and the window glass, enhance the sealing performance, and at the same time, change the sliding friction between the water-cut lip and the window glass into rolling friction. While maintaining the sealing performance of the window, it reduces the noise of friction between the water-cut lip and the window glass when the load increases.

[0013] A controller is fixedly installed on the inner panel of the door. The forward and reverse motors are connected to the controller via wires. The controller is also electrically connected to the window lift switch touch sensor. When the window lift switch touch sensor does not respond, i.e., when the glass is stationary for a long time, the forward and reverse motors rotate counterclockwise or clockwise by a certain angle. The water-cut lip or rotating roller connected to the flexible support plate presses tightly against the glass, increasing the load and ensuring sealing performance. When the window lift switch touch sensor responds, i.e., during or before and after the glass is raised or lowered, the window lift switch transmits a signal to the forward and reverse motors through the controller. The forward and reverse motors rotate clockwise or counterclockwise by a certain angle, thereby reducing the load and the probability of abnormal noise. At the same time, the rotating roller changes the sliding connection between the water-cut lip and the door glass into a rolling connection, improving the smoothness of the glass raising and lowering.

[0014] The water-cutting body is made of PP plastic (polypropylene, a semi-crystalline thermoplastic), EPDM plastic (ethylene propylene diene monomer is a terpolymer of ethylene, propylene and non-conjugated dienes), or PVC (polyvinyl chloride); the water-cutting lip assembly is made of TPE (Thermoplastic Elastomer, a thermoplastic elastomer material with high strength, high resilience, injection molding capability, wide range of applications, environmentally friendly, non-toxic and safe, and excellent colorability), EPDM plastic, or PVC; the inner door panel is made of steel or aluminum.

[0015] A car door includes a door sheet metal, a window glass, and a window lift switch. It also includes an adjustable load inner door water cutter, which is fixed to the door sheet metal. The water cutter's lip is adjacent to the window glass and can be tightly pressed against the window glass. The touch sensor of the window lift switch is connected to the controller wire.

[0016] An automobile includes a body sheet metal and a door, the door being rotatably connected to the side wall of the body sheet metal.

[0017] Beneficial effects

[0018] The invention has a simple structure and the compressive load of the water-cut lip is adjustable. When considering sealing performance, the compressive load of the inner water-cut lip can be increased to enhance the door's sealing performance, reduce noise caused by poor sealing, and reduce rainwater leakage into the door. When considering the smoothness of glass lifting, the compressive load of the inner water-cut lip can be decreased to facilitate smooth and rapid glass lifting and reduce friction noise caused by glass lifting.
