Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to a silent door water-cooling system, a door, and an automobile. Background Technology

[0002] The inner and outer water deflector of a car door is a rubber product installed on the inner panel of the door. It is mainly used to clamp the glass to achieve a sealing function, and also has the functions of defrosting, dewatering and dust removal. When the glass is raised or lowered, the edge of the water deflector slides relative to the glass surface to achieve a sealing effect. However, when the load on the water deflector is unevenly distributed or the surface lint is not clean enough, the water deflector is prone to producing abnormal noise, which seriously affects the driving experience. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a silent door water-cutting system. A cam is integrated into the inner and lower part of the water-cutting lip. The rotation of the cam achieves a dynamic sealing mode for the door water-cutting system. The cam motor is connected to the window lift button. When the glass is stationary, the water-cutting system is in sealing mode; the cam rotates, pressing the lip to form a seal. When the glass is raised or lowered, the water-cutting cam rotates at a certain angle, separating the lip from the glass, creating a silent mode and improving the driving experience. Simultaneously, a magnet is built into the lip where the water-cutting body contacts the sheet metal, forming a magnetic fixation that facilitates disassembly and enhances the sealing effect.

[0004] This invention proposes a silent car door water cutting system, including a water cutting body, a car door inner panel, a first cam roller, a second cam roller, and at least one electric motor;

[0005] The water-cutting body is elastically snapped onto the upper part of the inner door panel, and the upper end of the water-cutting body and the corresponding position of the inner door panel can be opened and closed to seal and fix it, so that the upper end of the water-cutting body can be firmly fixed to the upper part of the inner door panel, avoiding vibration during vehicle driving and the upper end of the water-cutting body hitting the inner door panel to produce abnormal noise. At the same time, it can also prevent rainwater from seeping between the water-cutting body and the inner door panel and corroding the corresponding area of ​​the inner door panel.

[0006] The water-cutting body has a water-cutting lip on the side corresponding to the car window glass. The water-cutting lip is in contact with the car window glass. When the car window glass moves up and down, the water-cutting lip maintains its initial contact state to prevent the water-cutting lip from rubbing against the moving car window glass and causing abnormal noise. There is a groove at the connection between the water-cutting lip and the water-cutting body. The first cam roller is suspended and accommodated in the groove. The end shaft of the first cam roller is connected to the corresponding position of the inner panel of the car door. The protrusion of the first cam roller can rotate and press against the adjacent water-cutting lip. The end of the water-cutting lip that rotates and presses against the first cam roller can be in close contact with the car window glass. When the car window glass is stationary, the protrusion of the first cam roller rotates and presses against the corresponding water-cutting lip, causing the upper end of the water-cutting lip to move towards the car window glass, and finally in close contact with the car window glass to achieve a sealing effect.

[0007] The water-cutting body below the water-cutting lip has a clearance groove on the side near the car window glass. A second cam roller is adjacent to this clearance groove. The end shaft of the second cam roller is connected to the corresponding position of the inner door panel. The convex part of the rotating second cam roller is adjacent to the clearance groove, and the convex part of the rotating second cam roller can make tight contact with the car window glass. When the car window glass is stationary, the convex part of the second cam roller rotates and presses against the aligned car window glass, which plays a double sealing role. When the car window glass moves up and down, the convex part of the second cam roller releases the pressure from the car window glass, maintaining the second cam roller in contact with the car window glass, avoiding the second cam roller from touching and rubbing against the moving car window glass and producing abnormal noise.

[0008] At least one motor shaft is connected to one end of the first cam roller and / or the second cam roller, and at least one motor is fixed to the corresponding position on the inner panel of the door. Depending on the number of motors installed, the first cam roller and the second cam roller can be rotated in different directions or rotated in the same direction.

[0009] The first cam roller and the second cam roller have completely identical structures. The first cam roller includes a first elongated roller body and a first rotating shaft. The cross-sectional shape of the first elongated roller body is a flattened ellipse. The first rotating shaft is inserted and fixed inside the first elongated roller body, and both ends of the first rotating shaft protrude outside the end faces of the first elongated roller body. The second cam roller includes a second elongated roller body and a second rotating shaft. The second rotating shaft is inserted and fixed inside the second elongated roller body, and both ends of the second rotating shaft protrude outside the end faces of the second elongated roller body. The second cam roller also includes two rows of sweeping bristles, which are respectively fixed to the cross-section. On the short shaft ends of the second elongated roller, which is flat and elliptical, a row of bristles that contact the window glass can wipe away dirt or water droplets when the window glass moves up and down, preventing water stains or dirt from adhering to the window glass and thus affecting the visibility of passengers through the window glass; two motors are respectively shaft-connected to one end of the first rotating shaft and one end of the second rotating shaft exposed on the same side. The first rotating shaft and the second rotating shaft are each equipped with a motor, and different rotation angles can be set for the first rotating shaft and the second rotating shaft according to product needs to control the pressing force between the two rotating shafts and the window glass.

[0010] The first cam roller and the second cam roller have completely identical structures. The first cam roller includes a first elongated roller body and a first rotating shaft. The cross-sectional shape of the first elongated roller body is a flattened ellipse. The first rotating shaft is fixed inside the first elongated roller body, and both ends of the first rotating shaft protrude outside the end faces of the first elongated roller body. The second cam roller includes a second elongated roller body and a second rotating shaft. The second rotating shaft is fixed inside the second elongated roller body, and both ends of the second rotating shaft protrude outside the end faces of the second elongated roller body. The second cam roller also includes two rows of sweeping bristles, which are respectively fixed... The short shafts of the second elongated roller, which has a flat elliptical cross-section, are positioned at both ends. Their function is to wipe away dirt or water droplets on the windshield when it moves up and down, preventing water stains or dirt from adhering to the windshield and thus affecting the visibility of passengers. An electric motor shaft is connected to one end of the exposed first rotating shaft, and the other end of the first rotating shaft is connected to the same side of the second rotating shaft via a transmission belt. This structure can keep the first and second rotating shafts rotating synchronously and in a directional manner, saving the production cost of an electric motor.

[0011] The first cam roller includes a first elongated roller body and a first rotating shaft. The first elongated roller body is cylindrical in shape, with a first arc-shaped protrusion protruding along the length of its sidewall. The sidewall of the cylinder is adjacent to the corresponding water-cutting lip and the sidewall of the water-cutting body, respectively. The first arc-shaped protrusion can be rotatably pressed against the corresponding water-cutting lip, and is adjacent to the sidewall of the corresponding water-cutting body. The first rotating shaft is inserted and fixed inside the first elongated roller body, with both ends of the first rotating shaft protruding outside the end faces of the first elongated roller body. The second cam roller includes a second elongated roller body, a second rotating shaft, and two rows of sweeping bristles. The second rotating shaft is inserted and fixed inside the second elongated roller body, and... The two ends of the second rotating shaft are exposed outside the two end faces of the second long strip-shaped roller body; the second long strip-shaped roller body is a cylinder in whole, and two second arc-shaped protrusions are provided on the side wall of the cylinder along its length. The side wall of the cylinder is adjacent to the side wall of the water-cutting body and the window glass respectively. One second arc-shaped protrusion can be rotated and pressed against the window glass, and the other second arc-shaped protrusion can be adjacent to the corresponding clearance groove; two rows of sweeping bristles are symmetrically protruding on the side wall of the cylinder perpendicular to the line connecting the two second arc-shaped protrusions along its length. Each row of sweeping bristles can rotate and contact the window glass; two motors are respectively shaft-connected to one end of the first rotating shaft and one end of the second rotating shaft exposed on the same side.

[0012] A magnetic sheet is installed inside the upper part of the water cutter body, and the upper part of the water cutter body is magnetically sealed and fixed to the inner panel of the corresponding door through the magnetic sheet.

[0013] A multi-directional jet assembly is fixedly installed on the side wall of the water-cutting body between the water-cutting lip and the avoidance strip groove. The multi-directional jet assembly includes a multi-directional jet nozzle and an air pump. The multi-directional jet nozzle is exposed and fixed outside the side wall of the water-cutting body, and the air pump is fixed to the inner panel of the door. The multi-directional jet nozzle and the air pump are connected through an air pipe. The function of the multi-directional jet nozzle is to controllably spray air to dry the glass surface when the window glass moves up and down, thereby reducing the impact of water stains on the glass surface on the vision.

[0014] A felt layer is provided on the side of the water-cut lip corresponding to the glass. The felt layer can prevent abnormal noises generated during the friction contact between the elastic water-cut lip and the dry glass surface.

[0015] The second long strip roller is made of felt to prevent abnormal noises from occurring during the rotation and pressing process between the second long strip roller and the dry glass surface.

[0016] A vehicle door includes a door sheet metal, a window glass, and a window lift switch. It also includes a silent door water-cooling system fixed to the door sheet metal. The controller of the window lift switch is connected to the wiring of each motor and air pump. When the window lift switch controls the glass to rise or fall, the controller sends commands to the motors and air pumps. The motors control the first and second cam rollers to rotate in a specific direction. The convex portions of the first and second cam rollers disengage from the glass, causing the glass to rise and fall silently. The air pump sprays air onto the glass through multi-directional nozzles, blowing out dirt and water stains. When the glass is stationary, the controller again sends commands to the motors and air pumps. The motors control the first and second cam rollers to rotate in a specific direction, and the convex portions of the first and second cam rollers press against the glass.

[0017] An automobile includes a body sheet metal and a door, the door being rotatably connected to the side wall of the body sheet metal.

[0018] Beneficial effects

[0019] This invention integrates a cam on the inner side and lower part of the water-cutting lip of the car door. The rotation of the cam achieves a dynamic sealing mode for the water-cutting lip. The cam motor is connected to the window lifting button. When the glass is stationary, the water-cutting lip is in sealing mode, and the cam rotates to press the lip and form a seal. When the glass is raised or lowered, the water-cutting cam rotates at a certain angle, and the lip separates from the glass, forming a silent mode and improving the driving experience. At the same time, the lip where the water-cutting body contacts the sheet metal has a built-in magnet to form a magnetic fixation, which is convenient for disassembly and improves the sealing effect.
