[0002] At present, in the traditional stamped door structure, the boundary of the window glass slides in the guide groove formed between the window frame outer panel and the window frame sheet metal to complete the lifting function of the glass. Therefore, the glass will be lower than the outer surface of the window frame outer panel in the width direction of the vehicle, thereby forming a step in the width direction. For ordinary models, the step height (i.e., the spacing between the outer surface of the window glass and the outer surface of the window frame outer panel in the width direction of the vehicle) is more than 3mm, which will increase the wind resistance coefficient of the vehicle during driving and have an adverse effect on the wind noise and waterproof function of the vehicle.

[0003] In the prior art, there are also structures with zero face difference between the window glass and the window frame outer panel in the vehicle width direction, which are mainly found in frameless doors. The sealing strips are expensive, high in cost, and complex in manufacturing process. There are also some framed windows that adopt zero face difference structures, but their structures are simple, the lifting resistance of the window glass is large, and there will be a large abnormal sound during the lifting process of the window glass, and there are problems such as difficulty in installing the window glass and its sealing strip.

[0004] Based on the above problems, it is urgent to develop a new type of zero-face difference sealing structure for the side edge of the window glass with good performance. Utility Model Content

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] Embodiment 1

[0035] This embodiment relates to a vehicle door sealing structure, which is used between the side edge of the vehicle window glass 1 and the window frame, and can reduce the lifting resistance of the vehicle window glass 1; an exemplary structure thereof is as follows Figure 1 , Figure 2 and Figure 3 shown.

[0036] In general, the door sealing structure includes a sealing strip 5 provided between the window frame sheet metal 2 and the window frame outer trim 3, and a guide arm 12 provided on the inner side of the side portion of the window glass 1. The sealing strip 5 includes a main body 50 provided with a slide groove 500, and a slider 120 is provided at the end of the guide arm 12. The slider 120 slides in the slide groove 500 as the window glass 1 is raised or lowered. In addition, a magnetic strip 60 is provided in the slider 120, and a magnetic field plate 6 corresponding to the slide groove 500 is provided in the main body 50. Due to the magnetic force between the magnetic field plate 6 and the magnetic strip 60, the slider 120 is suspended in the slide groove 500 with a gap between the inner wall of the slide groove 500.

[0037] Specifically, if Figure 2As shown, in the cross section of the sealing strip 5, the slide groove 500 of this embodiment is circular, and the magnetic field plate 6 is arc-shaped and arranged around the slide groove 500. Accordingly, it is preferred that the slider 120 is also set to be cylindrical with the shape of the slide groove 500, and the magnetic strip 60 is arranged along the axis of the slider 120, and a gap is left between the slider 120 and the inner wall of the slide groove 500, and the gap size of the gap is preferably set between 0.2mm and 0.5mm; for example, it can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc. Setting a reasonable gap size between the slider 120 and the inner wall of the slide groove 500 can not only ensure that the slider 120 is separated from the inner wall of the slide groove 500 without friction in the magnetic suspension state, but also ensure the guiding sliding effect of the slider 120 in the slide groove 500 when the slider 120 is not in the magnetic suspension state.

[0038] Setting the cross-sections of the slide groove 500 and the slider 120 to be circular not only facilitates processing and construction, but also allows the magnetic field plate 6 to form an annular magnetic field, thereby forming a balanced force distribution with the magnetic strip 60 located at the axis of the slider 120, which is beneficial to improving the suspension effect of the slider 120 in the slide groove 500 and ensuring the balance of the gap distribution between the circumferential surface of the slider 120 and the inner wall of the slide groove 500.

[0039] The material of the guide arm 12 is preferably plastic integrally formed; in particular, the part where the slider 120 is located is formed by ABS engineering plastic. ABS engineering plastic (i.e. PC+ABS, engineering plastic alloy) has both the excellent heat and weather resistance, dimensional stability and impact resistance of PC resin and the excellent processing fluidity of ABS resin, which is not only easy to process and form, but also meets the sliding setting requirements in the slide groove 500.

[0040] Still Figure 1 As shown, relative to the end where the slider 120 is located, the other end of the guide arm 12 is provided with a connecting seat 121, and the guide arm 12 of this embodiment is bonded to the vehicle window glass 1 through the colloid 11. The guide arm 12 is fixed to the vehicle window glass 1 by bonding, which is convenient for assembly operation and will not damage the structure of the vehicle window glass 1.

[0041] Based on the arrangement of the guide arm 12, preferably, in the left-right direction of the vehicle, the outer surfaces of the window frame sheet metal 2 and the window frame outer panel 3 of this embodiment are arranged flush, and a gap is left between the window frame sheet metal 2 and the window frame outer panel 3. At the same time, the sealing strip 5 also includes a first lip edge 51 connected to the main body 50, and the first lip edge 51 is located on the side of the guide arm 12 facing the window frame outer panel 3, and is specifically arranged at the end of the outer connecting arm 501 of the main body 50. The first lip edge 51 forms a seal between the vehicle window glass 1 and the window frame outer panel 3.

[0042] Based on the setting of the guide arm 12, the window glass 1 and the window frame outer panel 3 adopt a zero-face difference structure, so that there is no step between the window glass 1 outside the window and the window frame outer panel 3, which is conducive to reducing the wind resistance generated by the window part during the vehicle driving process. It is conducive to the first lip edge 51 on the sealing strip 5 to achieve the sealing between the window glass 1 and the window frame outer panel 3, forming a first seal, while ensuring good sealing between the window glass 1 and the window frame, making the connection between the window glass 1 and the window frame outer panel 3 smoother and tighter.

[0043] It should be noted that the vehicle window glass 1 of this embodiment can be a single-layer glass structure or a double-layer glass structure. When a double-layer glass structure is adopted, the two layers of glass can be bonded together by glass glue 10.

[0044] In addition, in this embodiment, the sealing strip 5 further includes an inner connecting arm 502 connected to the main body 50, and a second lip 52 provided at the end of the inner connecting arm 502. The inner connecting arm 502 is located on the side of the guide arm 12 facing away from the window frame exterior panel 3, and the second lip 52 abuts against the vehicle window glass 1. The second lip 52 is provided on the inner connecting arm 502 on the inner side of the guide arm 12, and the second lip 52 abuts against the inner surface of the vehicle window glass 1 on the side of the connecting seat 121 of the guide arm 12 away from the window frame, so that the guide arm 12 is located as a whole in the closed space formed between the first lip 51 and the second lip 52, which not only achieves the concealment effect of the guide sliding structure, but also the second lip 52 forms a second seal between the vehicle window glass 1 and the window frame, thereby further improving the sealing effect between the vehicle window glass 1 and the window frame.

[0045] In addition, in this embodiment, a mounting seat 4 is provided between the window frame sheet metal 2 and the window frame outer panel 3, and a mounting groove 40 is formed on the mounting seat 4, and the sealing strip 5 is clamped in the mounting groove 40. By providing the mounting seat 4 between the window frame sheet metal 2 and the window frame outer panel 3 and installing the sealing strip 5 in the mounting groove 40 on the mounting seat 4 by clamping, the installation operation of the sealing strip 5 can be made more convenient, and the installation reliability of the sealing strip 5 can be guaranteed.

[0046] In order to improve the reliability of the above-mentioned clamping structure, Figure 1 Combined with Figure 2 , Figure 3 As shown, a first clamping groove 503 is provided at the root of the outer connecting arm 501 of the sealing strip 5, and a first clamping protrusion 30 is provided on the inner side of the end of the window frame outer decorative panel 3, and the first clamping protrusion 30 is clamped in the first clamping groove 503; a second clamping groove 504 is provided in the middle of the inner connecting arm 502 of the sealing strip 5, and a second clamping protrusion 41 is provided on the inner wall of the mounting seat 4, and the second clamping protrusion 41 is clamped in the second clamping groove 504; in this way, the sealing strip 5 can be firmly clamped in the mounting groove 40.

[0047] Based on the setting of the inner connecting arm 502, it is preferred to set an insertion slot 505 for inserting the window frame interior panel 7 on the inner connecting arm 502. Providing the insertion slot 505 on the inner connecting arm 502 provides good conditions for the concealed installation of the edge of the window frame interior panel 7 and is conducive to improving the overall installation stability of the sealing strip 5.

[0048] In summary, the door sealing structure of the present embodiment is provided with a guide arm 12 on the inner side of the side portion of the vehicle window glass 1, and the guide arm 12 can be extended toward the side of the window frame inside the vehicle, so that the slider 120 is slid into the slide groove 500 on the sealing strip 5, thereby realizing the guiding and lifting function of the vehicle window glass 1, which provides convenient conditions for the zero-face difference setting of the vehicle window glass 1 and the window frame exterior panel 3; by providing a magnetic strip 60 in the slider 120 and providing a magnetic field plate 6 in the main body 50 of the vehicle window glass 1, the slider 120 is suspended in the slide groove 500 by utilizing the magnetic levitation effect, thereby avoiding the friction between the slider 120 and the inner wall of the slide groove 500, thereby greatly reducing the lifting and lowering resistance of the vehicle window glass 1.

[0049] Embodiment 2

[0050] This embodiment relates to a vehicle, in which the door sealing structure provided in the first embodiment is used between the window frame and the window glass 1 of the vehicle.

[0051] By adopting the sealing solution of the above-mentioned vehicle door sealing structure, the problems of high cost, high process requirements, low tolerance, high failure rate, poor sealing effect, etc. of frameless vehicle doors are avoided; and a zero face difference setting between the vehicle window glass 1 with a window frame and the window frame exterior panel 3 is achieved.

[0052] At the same time, since the magnetic strip 60 is arranged in the slider 120 and the magnetic field plate 6 is buried in the main body 50, the problems of large lifting resistance of the window glass 1, easy lateral deviation of the glass, loud noise and easy wear in the current zero-face difference setting of the framed door are solved.

[0053] The above-mentioned door sealing structure can be integrally matched on both sides of the windows of the front and rear doors, for example, the side of the front door window or the rear door window corresponding to the B-pillar position, the side of the front door window corresponding to the A-pillar position, etc.

[0054] When the magnetic suspension components are specifically assembled and set, the magnetic field generation state of the magnetic field plate 6 can be controlled by powering on the entire vehicle, and power is only turned on when the window glass 1 needs to be raised or lowered. The magnetic field plate 6 is combined with the sealing strip 5 by co-extrusion, and the thickness of the rubber coating is designed to be about 2mm. Figure 3 As shown in FIG. 1 , the magnetic field plate 6 is preferably divided into two symmetrical parts, each of which forms a half-moon-shaped surround on the magnetic strip 60 at the center. When the magnetic field plate 6 is energized, a magnetic field is generated between the magnetic field plate 6 and the magnetic strip 60. Figure 3 The forces indicated by the arrows.

[0055] The magnetic strip 60 is preferably a strong magnetic strip with a radius R=0.5mm, and the radius of the slider 120 is set at about 5mm. In this way, the spacing between the magnetic field plate 6 and the magnetic strip 60 is approximately about 7.5mm. The force exerted by the magnetic field plate 6 on the magnetic strip 60 can be set within the range of 8±1.5N for every 100mm length.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
