Description

Technical Field

[0001] This invention relates to the field of automotive window assembly manufacturing, and in particular to a vehicle window ventilation device. Background Technology

[0002] Currently, the proportion of cars equipped with panoramic sunroofs in the automotive market is increasing. These models typically use a method where the sunroof glass is directly glued to the car's frame to form a closed roof. Therefore, the sunroof cannot be opened for ventilation, failing to meet the needs of passengers for air exchange. Especially at high speeds, opening the window for ventilation creates significant wind noise inside the car, negatively impacting the passenger experience. To address these issues, Chinese patent literature discloses an interior panoramic sunroof (application number 201710660865.4), which employs a segmented structure, designing the panoramic sunroof into two sections, front and rear, with a tilting mechanism to control the tilting of the front glass for ventilation. To ensure a tight seal between the two glass sections, a sealing strip is required at the joint. However, this sealing strip compromises the overall integrity of the panoramic sunroof, and the tilting mechanism increases the roof thickness, affecting aesthetics. Furthermore, it significantly increases the requirements for sealing performance and the difficulty of car assembly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a vehicle window ventilation device that reduces the assembly and production difficulty of the panoramic sunroof while realizing ventilation of the panoramic sunroof.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A vehicle window ventilation device has a ventilation port on the edge or center of the vehicle window glass, and the vehicle window ventilation device is embedded in the ventilation port, including an electromagnetic adsorption mechanism, a movable component, a magnetic component and a fixing component.

[0006] The fixed component is arranged along the air vent, and the movable component is embedded in the fixed component and hinged to the fixed component, with the hinge point located between the air-permeable end of the movable component and the limiting end of the movable component.

[0007] The electromagnetic adsorption mechanism is arranged opposite to the magnetic suction component, and the limiting end of the movable component and the fixed component are adsorbed or separated by the electromagnetic adsorption mechanism and the magnetic suction component.

[0008] When the electromagnetic adsorption mechanism adsorbs the magnetic component, the vent end of the movable component connects to the inner and outer spaces of the vehicle window glass.

[0009] When the electromagnetic adsorption mechanism separates from the magnetic adsorption component, the ventilated end of the movable component seals the inner and outer spaces of the vehicle window glass.

[0010] The beneficial effects of this invention are as follows: by cooperating with the electromagnetic adsorption mechanism and the magnetic suction component, the movable component is driven to rotate relative to the fixed component, thereby realizing the opening and closing control of the ventilation end of the movable component. There is no need to add a drive mechanism or design the glass in sections. The ventilation of the panoramic sunroof can be realized by using the adsorption control of the electromagnet. The structure is simple and easy to produce and assemble. Attached Figure Description

[0030] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please refer to Figures 1-12 A vehicle window ventilation device, wherein a ventilation port is provided on the edge or center of the vehicle window glass, and the vehicle window ventilation device is embedded in the ventilation port, including an electromagnetic adsorption mechanism, a movable component, a magnetic component and a fixed component;

[0032] The fixed component is arranged along the air vent, and the movable component is embedded in the fixed component and hinged to the fixed component, with the hinge point located between the air vent end and the limiting end of the movable component.

[0033] The electromagnetic adsorption mechanism and the magnetic suction component are arranged opposite to each other, and the limiting end of the movable component and the fixed component are adsorbed or separated by the electromagnetic adsorption mechanism and the magnetic suction component;

[0034] When the electromagnetic adsorption mechanism adsorbs the magnetic component, the vent end of the movable component connects the inner and outer spaces of the car window glass.

[0035] When the electromagnetic adsorption mechanism separates from the magnetic adsorption component, the vent end of the movable component seals the space on both the inside and outside of the window glass.

[0036] The working principle of this invention is as follows:

[0037] By controlling the connection between the electromagnetic adsorption mechanism and the magnetic suction component, the position of the ventilated end of the moving component can be controlled, and the opening and closing control of the ventilated end can be achieved without adding a lifting mechanism.

[0038] As can be seen from the above description, the beneficial effects of the present invention are as follows: by cooperating with the electromagnetic adsorption mechanism and the magnetic suction component, the movable component is driven to rotate relative to the fixed component, thereby realizing the opening and closing control of the ventilation end of the movable component. There is no need to add a drive mechanism or make the glass adopt a segmented design. The ventilation of the panoramic sunroof can be realized by using the adsorption control of the electromagnet. The structure is simple and easy to produce and assemble.

[0039] Furthermore, one of the electromagnetic adsorption mechanism and the magnetic adsorption component is located at the limiting end of the movable component, and the other is located on the fixed component.

[0040] Furthermore, the fixing assembly includes a fixing cover, a sealing element, and a bracket for mounting the electromagnetic adsorption mechanism or magnetic adsorption element;

[0041] One end of the fixed cover is connected to the lower side of the sunroof glass, and the other end of the fixed cover extends into the ventilation opening. The sealing element is connected to the other end of the fixed cover, and the limiting end of the movable component abuts against the sealing element.

[0042] As described above, the sealing element is used to seal the gap formed between the fixed cover and the limiting end of the movable component to ensure sealing. The bracket is used to provide support between the two ends of the fixed cover, which facilitates the installation of the electromagnetic adsorption mechanism or magnetic component and improves the stability of the electromagnetic adsorption mechanism or magnetic component.

[0043] Furthermore, the fixed cover has a downwardly extending extension at one end inside the vent, and a seal is installed on the side of the extension facing the vent.

[0044] As described above, the extension is provided to provide an installation position for the seal and improve the sealing between the fixed cover and the moving component.

[0045] Furthermore, the movable component includes a movable cover and a stop for abutting against the fixed component;

[0046] The movable cover is hinged to the fixed component;

[0047] The movable cover has an exhaust grille and a stop block at each end, and the stop block is connected to the side of the movable cover away from the exhaust grille.

[0048] As described above, the stop block limits the movement of the cover, ensuring that the fixed component can limit the movement of the cover and improve reliability.

[0049] Furthermore, the plane containing the exhaust grille forms a first angle of 10 to 110° with the outside of the moving component.

[0050] As can be seen from the above description, the formation of the first included angle can ensure the sealing between the plane where the exhaust grille is located and the automotive sheet metal.

[0051] Furthermore, the hinge point is located near the limiting end of the active component.

[0052] As described above, the hinge point is located near the limiting end of the movable component. When the electromagnetic adsorption mechanism separates from the magnetic adsorption component, the two ends of the movable component are in an unbalanced state, which in turn allows the ventilated end of the movable component to quickly reset, ensuring that the ventilated end of the movable component is closed and improving reliability.

[0053] Furthermore, the portion of the active component between the hinge point and the limiting end has a first weight;

[0054] The portion of the moving component between the hinge point and the ventilated end has a second weight.

[0055] The second weight must be at least twice the first weight.

[0056] As can be seen from the above description, when the second weight is at least twice the first weight, it can ensure that the ventilated end and the limiting end of the moving component quickly enter an unbalanced state after the adsorption force of the electromagnetic adsorption mechanism is removed, ensuring that the ventilated end quickly resets and improving the reliability of the moving component's movement process.

[0057] Furthermore, when the electromagnetic adsorption mechanism separates from the magnetic adsorption component, the exterior of the movable component is flush with or embedded in the exterior of the window glass.

[0058] As described above, the top of the movable component is flush with or lower than the top of the sunroof glass. This serves two purposes: reducing wind resistance and reducing wind noise. Preferably, the top of the movable component should be flush with the top of the sunroof glass.

[0059] Furthermore, when the magnetic suction device is installed on the movable component, the magnetic suction device is located between the hinge point and the limiting end of the movable component.

[0060] As described above, placing the magnetic suction element on the movable component reduces the weight of the limiting end of the movable component and lowers the suction force requirement of the electromagnetic suction mechanism.

[0061] Furthermore, the side of the electromagnetic adsorption mechanism facing the magnetic element forms a second included angle of 0° to 10° with the magnetic element.

[0062] As can be seen from the above description, the second included angle within this angle range enables the electromagnetic adsorption mechanism to quickly adsorb magnetic components.

[0063] The ventilation device for vehicle windows in this invention can be installed on the windows or sunroofs of various types of vehicles. In this embodiment, it mainly refers to the sunroof.

[0064] Please refer to Figures 1-12 Embodiment 1 of the present invention is as follows:

[0065] A vehicle window ventilation device includes a ventilation opening 11 at the edge or center of the window glass 1. The ventilation device is embedded in the ventilation opening 11 and includes an electromagnetic adsorption mechanism 2, a movable component 3, a magnetic suction element 4, and a fixed component 5. The fixed component 5 is arranged along the ventilation opening 11, and the movable component 3 is embedded in the fixed component 5 and hinged to the fixed component 5, with the hinge point located between the ventilated end 31 and the limiting end 32 of the movable component 3. The electromagnetic adsorption mechanism 2 is arranged opposite to the magnetic suction element 4, the magnetic suction element 4 is connected to the movable component 3, and the electromagnetic adsorption mechanism 2 is connected to the fixed component 5. The electromagnetic adsorption mechanism 2 can connect to or separate from the magnetic suction component 4, thereby changing the positional relationship between the fixed component 5 and the limiting end 32 of the movable component 3. In other equivalent embodiments, the electromagnetic adsorption mechanism 2 can interchange positions with the magnetic suction component 4 to control the state of the movable component 3. When the electromagnetic adsorption mechanism 2 adsorbs the magnetic suction component 4, the vent end 31 of the movable component 3 is higher than the top of the window glass 1, and the limiting end 32 of the movable component 3 abuts against the fixed component 5. When the electromagnetic adsorption mechanism 2 separates from the magnetic suction component 4, the vent end 31 of the movable component 3 is lower than the top of the window glass 1. Specifically, when the electromagnetic adsorption mechanism 2 separates from the magnetic suction component 4, the top of the movable component 3 is flush with or lower than the top of the window glass 1. Preferably, the top of the movable component 3 is flush with the top of the window glass 1, that is, the top of the movable component 3 and the outer surface of the window glass 1 form a smooth arc surface, and when the electromagnetic adsorption mechanism 2 separates from the magnetic suction component 4, there is a gap between the top of the electromagnetic adsorption mechanism 2 and the magnetic suction component 4.

[0066] Optionally, the ventilation port 11 is located in the central area, rear side, front side, or left and right sides of the window glass 1. Preferably, in this embodiment, the ventilation port 11 is located on the front side of the window glass 1, and the ventilation end is located close to the windshield of the car.

[0067] In this embodiment, the fixing component 5 includes a fixing cover 51, a sealing element 52, and a bracket 53 for mounting the electromagnetic adsorption mechanism 2. One end of the fixing cover 51 is connected to the lower side of the window glass 1, and the other end of the fixing cover 51 extends towards the ventilation port 11. The sealing element 52 is connected to the other end of the fixing cover 51, and the limiting end 32 of the movable component 3 abuts against the sealing element 52. The end of the fixing cover 51 located inside the ventilation port 11 has a downwardly extending extension 54, and the sealing element 52 is installed on the side of the extension 54 facing the ventilation end 31. Specifically, one end of the fixing cover 51 can be connected to the lower side of the window glass 1 by adhesive, snap-fit, or bolt fastening. Preferably, one end of the fixing cover 51 is bonded to the lower side of the window glass 1 by an adhesive strip 55; the sealing element 52 is a sealing strip.

[0068] In this embodiment, the movable component 3 includes a movable cover 33 and a stop 34 for abutting against the fixed component 5; the movable cover 33 is hinged to the fixed component 5; an exhaust grille 35 and a stop 34 are respectively provided at both ends of the movable cover 33, and the stop 34 is connected to the side of the movable cover 33 away from the exhaust grille 35. Preferably, the magnetic component 4 is an iron sheet. The movable cover 33 has a matching mounting groove 331 on the side facing the fixed cover 51. The magnetic component 4 is embedded in the mounting groove 331, and the magnetic sheet is injection molded to the movable cover 33. The bottom of the magnetic component 4 protrudes outward from the mounting groove 331, with a protrusion thickness of 0.5mm. The fixed cover 51 has two symmetrically arranged buckles 37 on its lower side. The movable cover 33 is rotatably connected to the corresponding buckles 37 via two rotating shafts 36. Specifically, each buckle 37 has a through hole 371 matching the rotating shaft 36 and a sliding groove 372 communicating with the through hole 371. The width a of the sliding groove 372 is smaller than the diameter b of the through hole 371. Optionally, the vent holes on the exhaust grille 35 are rectangular, circular, or angled.

[0069] In this embodiment, the movable cover 33 and the fixed cover 51 may be made of PE, PP, PS, ABS, POM, PC, PVC or PP+GFX.

[0070] In this embodiment, the plane where the exhaust grille 35 is located forms a first included angle α with an angle of 10 to 110° with the outside of the movable component 3. Further, the angle of the first included angle α is 80° to 110°. Preferably, the angle of the first included angle α is 90°, 91°, 92°, 95°, 99°, 100°, 101° or 102°.

[0071] In this embodiment, a sealing strip 38 is bonded above the plane where the exhaust grille 35 is located to ensure a seal between the movable component 3 and the rear sheet metal of the vehicle. Furthermore, the end tongue 381 of the sealing strip 38 extends above the rear windshield 6 of the vehicle, and the plane where the exhaust grille 35 is located is always pressed against the end tongue of the sealing strip 38 to achieve a seal. The compression amount m is set to 0.5mm to 1mm from the lower end of the tongue to the top of the rear windshield 6.

[0072] In this embodiment, the hinge point is located near the limiting end 32 of the movable component 3, while the magnetic suction member 4 is located between the hinge point and the limiting end 32 of the movable component 3. The hinge point is located on the axis of the two rotating shafts 36.

[0073] In this embodiment, the portion of the movable component 3 along the axis of the hinge point to the limiting end 32 has a first weight; the portion of the movable component 3 along the axis of the hinge point to the venting end 31 has a second weight; the second weight is at least twice the first weight. Preferably, in this embodiment, the second weight is twice the first weight to avoid the second weight being too large, which would result in a greater demand for adsorption force when the electromagnetic adsorption mechanism 2 adsorbs the magnetic suction component 4.

[0074] In this embodiment, the top of the electromagnetic adsorption mechanism 2 and the magnetic suction member 4 form a second included angle β with an angle of 0° to 10°. Preferably, when the electromagnetic adsorption mechanism 2 is separated from the magnetic suction member 4, the angle of the second included angle β is 6°, 7°, 8°, 9° or 10°, and when the electromagnetic adsorption mechanism 2 adsorbs the magnetic suction member 4, the angle of the second included angle β is 0°.

[0075] In this embodiment, the electromagnetic adsorption mechanism 2 includes an electromagnet 21 and wires 22 for electrically connecting the N and S poles of the electromagnet 21 to the vehicle's power supply. The electromagnet 21 is embedded in the middle of the bracket 53, and there is a 0.5mm gap between the electromagnet and the top of the bracket 53. The S and N poles of the electromagnet 21 are respectively electrically connected to the positive and negative poles of the vehicle's power supply through a wire 22. A switch is provided between the electromagnet 21 and the vehicle's power supply to control the energization state of the electromagnet 21. The working principle of the electromagnet 21 is as follows: when the power is on, the electromagnet 21 is energized and becomes magnetic, thereby attracting the magnetic attractor 4. When the power is off, the electromagnet 21 loses its magnetism, thereby losing the attraction force on the magnetic attractor 4, causing the magnetic attractor 4 to separate from the electromagnet 21.

[0076] The working principle of this embodiment is as follows:

[0077] When the exhaust grille 35 is closed, the electromagnet 21 is de-energized, and the top of the movable cover 33 forms a smooth arc surface with the surface of the window glass 1. At this time, the second included angle β between the electromagnet 21 and the magnetic plate is 8°, the stop block 34 presses against the lower end of the seal 52, and the movable cover 33 and the seal 52 always remain pressed together.

[0078] When the exhaust grille 35 enters the exhaust state, the electromagnet 21 is energized and attracts the magnetic component 4. At this time, the movable cover 33 rotates, and the end of the movable cover 33 where the exhaust grille 35 is located gradually rises, the block 34 assembly sinks, the magnetic component 4 rotates at an angle of 8°, and until the second included angle β is 0°, the interior space and the exterior space are connected through the exhaust grille 35.

[0079] In summary, the present invention provides a vehicle window venting device that controls the magnetism of an electromagnet by switching it on and off, thereby changing the connection state between the electromagnet and the magnetic attractor. It utilizes the weight imbalance at both ends of the movable cover to change its state, achieving automatic control of the cover without the need for an additional lifting mechanism. This sunroof venting device, located locally within the sunroof glass, ensures both the strength and sealing of the sunroof glass without compromising its integrity, thus enabling air exchange between the inside and outside of the vehicle.

[0080] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
