According to the vehicle door assembly, the vehicle window glass positioned between the tops of the first limiting groove and the second limiting groove is bent towards the inner side of the vehicle window glass mounting frame to form a bending area, and the top of the bending area is abutted against the first sealing lip. The reason for this is that after the window glass top is raised beyond the first and/or second limit grooves, the window glass mounting frame cannot provide effective guidance to the window glass top before the window glass top comes into contact with the seal, and the window glass top may tilt to the outside of the vehicle door due to the presence of manufacturing errors or assembly errors. The bending area is formed by pre-bending the vehicle window, and has a trend of inclining towards the inner side of the vehicle door in the rising process of the vehicle window glass, so that the vehicle window can be prevented from inclining towards the outer side of the vehicle door, and the situation that the vehicle window glass is excessively inclined outwards and cannot be contacted with the sealing element due to errors can be avoided.

In the development process of the automobile, the side part of the automobile door is of an arc-shaped structure, and the limit grooves on the two sides of the mounting frame of the automobile window glass are inconsistent in length, so that an inwards bent area is designed on the upper part of the automobile window glass in order to prevent the automobile window glass from being outwards separated from the door frame in the ascending process of the automobile window glass, namely glass pre-bending treatment is carried out in the glass production process, and a step with a size D is formed between the outer side of the automobile window glass and the top sealing strip of the mounting frame of the automobile window glass. In order to ensure that the vehicle window is not separated from the mounting frame of the vehicle window glass, the dimension D is designed to be larger, generally 6mm-7mm, the wind resistance coefficient of the vehicle door is increased, and therefore extra wind resistance is generated in the running process of the vehicle, and the oil consumption is increased. In order to solve the problem, the applicant provides a novel vehicle door assembly, which has the following specific structure:
referring to fig. 1, in the door assembly provided by the invention, a window glass mounting frame 1 is arranged on a door, a mounting groove 11 is arranged on the inner side edge of the top of the window glass mounting frame 1, a window glass 2 is arranged in the window glass mounting frame 1 in a lifting manner, a sealing piece 3 comprises a clamping part 31, a first sealing lip 32, a second sealing lip 33 and a limiting part 34 which are connected to the clamping part 31, the clamping part 31 is arranged in the mounting groove 11, the first sealing lip 32 is abutted with the inner side of the top of the mounting groove 11, the second sealing lip 33 is positioned at the lower side of the first sealing lip 32, the limiting part 34 is positioned between the first sealing lip 32 and the second sealing lip 33, and when the window glass 2 presses the second sealing lip 33 to deform beyond a preset value, the limiting part 34 is suitable for being abutted with the second sealing lip 33 so as to limit the relative position of the top of the window glass 2 and the first sealing lip 32.
The sealing element 3 can be the shape of a common sealing strip in the field of vehicle sealing, and the clamping part 31 of the sealing element 3 is contacted with the inner side wall of the mounting groove 11, so that the tightness between the sealing element 3 and the window glass mounting frame 1 is ensured. During the lifting of the window pane 2, the window pane 2 can be lifted along the window pane mounting frame 1, the inner side of the window pane 2 being in contact with the second sealing lip 33 for sealing against the inner side of the window pane 2, the window pane 2 continuing to move to the top against the first sealing lip 32 for sealing against the outer side of the window pane 2, whereby a double seal is formed for ensuring tightness between the seal 3 and the window pane 2.
The limiting part 34 is located between the first sealing lip 32 and the second sealing lip 33, when the second sealing lip 33 is pressed and deformed by the window glass 2 to exceed a preset value, the limiting part 34 is abutted against the second sealing lip 33, and prevents the second sealing lip 33 from being deformed continuously, so that the window glass 2 is prevented from being inclined inwards, and the size of the limiting part 34 can be set reasonably according to the preset value. The contact position between the window glass 2 and the first sealing lip 32 can be limited, and the size of the step formed between the outer side of the window glass 2 and the outer side of the first sealing lip 32 (i.e. D in the figure) can be limited, so that the limiting part 34 can limit the deflection degree of the window glass 2 in the vehicle, reduce the size of the step formed between the outer side of the window glass 2 and the outer side of the first sealing lip 32, further reduce the wind resistance coefficient of the vehicle door, reduce the wind resistance of the vehicle door during the running process of the vehicle, and reduce the oil consumption of the vehicle. In addition, reducing the step size formed on the outer side of the window glass 2 and the outer side of the first sealing lip 32 also improves the aesthetic appearance of the vehicle door.
If the second sealing lip 33 is deformed by the window glass 2 by not more than a predetermined value, the second sealing lip 33 does not abut against the stopper 34. In the case where the second sealing lip 33 is deformed by the window pane 2 by compression not exceeding the preset value, it is indicated that the size of the step formed by the outer side of the window pane 2 and the first sealing lip 32 has a small influence on the windage or meets the design requirement, i.e. the size D of the step is within an acceptable size, and the person skilled in the art can determine the value of D according to routine wind tunnel experiments, and thus determine the specific value of the preset value.
The material of the sealing member 3 may be polyvinyl chloride (PVC), ethylene propylene rubber (EPDM), synthetic rubber modified polypropylene (PP-EPDM), etc. commonly used in the vehicle sealing field, and the limiting portion 34 may have a certain length dimension and a certain width dimension, so as to ensure that the sealing member 3 has sufficient strength to limit the deflection degree of the second sealing lip 33 under the extrusion of the window glass to exceed a preset value.
Referring to fig. 2, in one embodiment of the invention, the seal 3 includes a connecting segment 35 connected to the clip portion 31, the connecting segment 35 being located inside the first sealing lip 32 and extending downward, a stopper 34 being connected to the connecting segment 35, and the second sealing lip 33 being connected to an end of the connecting segment 35. Specifically, the clamping portion 31 includes a first protrusion 31a and a second protrusion 31b, the mounting groove is provided with protruding ridges corresponding to the two protrusions, respectively, and the first protrusion 31a and the second protrusion 31b can be abutted with the protruding ridges corresponding to each other, so as to avoid the sealing member 3 from falling off from the top of the window glass mounting frame, and simultaneously the first protrusion 31a and the second protrusion 31b can also play a role in sealing.
With continued reference to fig. 2, in the case where the clamping portion 31 provides a good fixing effect and sealing effect, the connecting section 35 extends downward from the side of the clamping portion 31 close to the vehicle interior, the connecting section 35 and the clamping portion 31 are L-shaped, and the connecting section 35 can also contact and seal with the window glass mounting frame at the corresponding position. Specifically, the end face of the connecting section 35 on the side facing the vehicle interior is provided with a third sealing lip 35a, and the corresponding position of the window glass mounting frame 1 may be provided with a groove in contact with the third sealing lip 35a, the third sealing lip 35a going deep into the groove, and the inner wall of the groove may press the third sealing lip 35a, thereby improving the sealing effect.
With continued reference to fig. 2, a second sealing lip 33 is provided at the end of the connecting section 35, and a stopper 34 is attached to the connecting section 35. As can be seen from fig. 2, the connection position of the connecting section 35 and the second sealing lip 33 is located below the connection position of the stopper 34 and the second sealing lip 33, and when the second sealing lip 33 is pressed by the window glass 2, the second sealing lip 33 is deflected in the direction of the vehicle interior side with the connection position with the end of the connecting section 35 as the rotation center, the end of the second sealing lip 33 is deflected in the direction of the stopper 34, and after the deflection degree of the second sealing lip 33 exceeds the preset value, the stopper 34 abuts against the second sealing lip 33, preventing the second sealing lip 33 from continuing to deflect, thereby being capable of facilitating the stopper 34 to restrict the deflection degree of the second sealing lip, and further restricting the inclination degree of the window glass toward the vehicle interior side.
Therefore, the joint portion 31 is used for connection and sealing with the mounting groove 11, and the connecting section 35 extending downward from the joint portion 31 extends the entire length of the seal member 3, increases the contact area with the window glass mounting frame 1, and improves the sealing property. The connecting section 35 and the clamping part 31 have a certain angle, the connecting section 35 and the clamping part 31 can be L-shaped, and the second sealing lip 33 is arranged at the end part of the connecting section 35, so that the first sealing lip 32 and the second sealing lip 33 are convenient to contact with the top and the side wall of the window glass 2 respectively, and the tightness between the sealing element 3 and the window glass 2 is improved.
Referring to fig. 2, in one embodiment of the present invention, the length of the second sealing lip 33 is greater than the length of the stopper 34. As can be seen from fig. 2, the second sealing lip 33 has a greater extent toward the vehicle exterior than the stopper 34. After the second sealing lip 33 is squeezed and deflected, the length of the second sealing lip 33 is sufficient to support the end or side wall of the second sealing lip 33 in contact with the limiting portion 34, preventing the second sealing lip 33 from being too short to cooperate with the limiting portion 34 and causing the limiting portion 34 to fail.
Referring to fig. 2, in one embodiment of the present invention, the stopper 34 is integrally formed with the seal 3. Can be manufactured through an integral molding process, so that the connection strength between the limiting part 34 and the sealing element 3 can be ensured, and the limiting part 34 is prevented from falling off from the sealing element 3.
Referring to fig. 1 and 2, in one embodiment of the invention, a deformation cavity 321 is provided within the first sealing lip 32. The deformation cavity 321 has a certain internal space, and when the top of the window glass 2 presses the first sealing lip 32, the end of the first sealing lip 32, which contacts the window glass 2, is deformed, so as to form a groove matched with the top of the window glass 2. The deformation cavity 321 can increase the deformation degree of the first sealing lip 32 and increase the depth of the groove, so that the contact area between the top of the window glass 2 and the first sealing lip 32 is increased, and the sealing performance of the first sealing lip 32 to the top of the window glass 2 is improved.
Referring to fig. 1, in one embodiment of the invention, the first sealing lip 32 is bent outwardly from the catch 31. The first sealing lip 32 is bent outwards from the clamping part 31, the upper end face of the first sealing lip 32 is in contact with the mounting groove 11, and the edge of the outer side of the mounting groove 11 can be covered, so that the contact area with the mounting groove is increased, and the sealing performance between the sealing element 3 and the mounting groove 11 is improved. And the lower end of the first sealing lip 32 forms an end face matched with the top of the window glass 2 by bending the first sealing lip 32 outwards, the window glass 2 can directly prop against the end face after rising, and the lower end face of the first sealing lip 32 can also play a role in buffering the movement of the window glass 2 while sealing the window glass 2.
Referring to fig. 1, in one embodiment of the present invention, the vertical distance between the outer surface of the first sealing lip 32 and the outer surface of the window glass 2 is denoted as D, and when the vertical distance D is greater than 3mm, the stopper 34 abuts against the second sealing lip 33.
When the window pane 2 is raised into contact with the seal 3, there is a vertical distance D between the outer surface of the first sealing lip 32 and the outer surface of the window pane 2, which vertical distance D is related to the degree to which the window pane 2 is tilted into the vehicle, the greater the degree to which the top of the window pane 2 is tilted into the vehicle, the greater the vertical distance D. The vertical distance D may be limited to within 3mm by the cooperation of the stopper 34 with the second sealing lip 33 by configuring the position and size of the stopper 34.
When the vertical distance D is less than 3mm, the stopper 34 and the second sealing lip 33 do not contact. When the vertical distance D is greater than 3mm, the stopper 34 abuts against the second sealing lip 33 so that the second sealing lip 33 cannot be deflected further into the vehicle interior, and since the degree of deflection of the second sealing lip 33 is related to the degree of tilting the top of the window glass 2 into the vehicle interior, the stopper 34 indirectly prevents the top of the window glass 2 from continuing to tilt into the vehicle interior by restricting the deflection of the second sealing lip 33, thereby restricting the contact position of the top of the window glass 2 with the first sealing lip 32 so that the vertical distance D is equal to 3mm. The vertical distance D between the outer surface of the first sealing lip 32 and the outer surface of the window glass 2 is always less than or equal to 3mm due to the presence of the limiting portion 34, so that the step formed between the window glass and the first sealing lip is prevented from being oversized, the wind resistance coefficient of the vehicle door is excessively large, and the running oil consumption of the vehicle is affected.
Referring to fig. 3, in one embodiment of the present disclosure, the front and rear sides of the window glass mounting frame 1 are provided with a first limit groove 12 and a second limit groove 13, respectively, the first limit groove 12 being smaller in length than the second limit groove 13, and the seal 3 is adapted to cooperate with the top edge of the window glass 2 located between the first limit groove 12 and the second limit groove 13.
The first and second limit grooves 12, 13 serve to guide the lifting movement of the window pane 2 during the lifting of the window pane 2. In order to meet the design of the vehicle itself, the length of the first limiting groove 12 is generally smaller than that of the second limiting groove 13, the first limiting groove 12 and the second limiting groove 13 can seal the side edges of the window glass 2 besides guiding, the sealing element 3 is located at the top of the first limiting groove 12 and the second limiting groove 13, the top of the window glass 2 between the first limiting groove 12 and the second limiting groove 13 can be sealed by the sealing element 3, and therefore the edges of the window glass are sealed completely.
Referring to fig. 3, in one embodiment of the present invention, the window glass 2 located between the tops of the first and second limiting grooves 12 and 13 is bent toward the inside of the window glass mounting frame 1 to form a bent region 21, and the top of the bent region 21 abuts against the first sealing lip 32. The reason for this is that after the top of the window glass 2 rises beyond the first limit groove 12 and/or the second limit groove 13, the window glass mounting frame 1 cannot effectively guide the top of the window glass 2 before the top of the window glass 2 comes into contact with the seal 3, and the top of the window glass 2 may be inclined to the outside of the vehicle door due to the presence of manufacturing errors or assembly errors. The bending region 21 is formed by pre-bending the window glass 2, and in the process of rising the window glass 2, the bending region 21 has a tendency to incline towards the inner side of the vehicle door, so that the top of the window glass can be prevented from inclining towards the outer side of the vehicle door, and the condition that the window glass 2 is excessively inclined outwards and cannot be contacted with the sealing element 3 due to errors can be avoided.
In one embodiment of the invention, the perpendicular distance D between the outer surface of the first sealing lip 32 and the outer surface of the vehicle pane 2 is 2mm to 3mm. The vertical distance D between the outer surface of the first sealing lip 32 and the outer surface of the window glass 2 is the size of the step, the size of the step can be more than or equal to 2mm by the first limiting groove 12, the second limiting groove 13 and the bending region 21 of the window glass 2, and the size of the step can be less than or equal to 3mm by the cooperation of the limiting part 34 and the second sealing lip 33. If the step is smaller than 2mm, it means that production errors or assembly errors may occur in the window glass 2 and components matched with the window glass 2, and the top part may be separated from the window glass mounting frame 1 in the process of lifting the window glass 2, so that maintenance is required. If the size of the step exceeds 3mm, the wind resistance coefficient of the vehicle door is increased, the wind resistance received during the running of the vehicle door is affected, and further the oil consumption is increased.
In one embodiment of the invention, a vehicle is provided comprising a body, and a door, a window pane 2 and a seal 3 as above. The vehicle door is provided with a vehicle window glass mounting frame 1, and a mounting groove 11 is formed in the inner side edge of the top of the vehicle window glass mounting frame 1. The window glass 2 is provided in the window glass mounting frame 1 so as to be vertically movable. The seal 3 includes a click-on portion 31, and a first sealing lip 32, a second sealing lip 33 and a stopper portion 34 connected to the click-on portion 31, the click-on portion 31 is provided in the mounting groove 11, the first sealing lip 32 abuts against the inside of the top of the window glass mounting frame 1, the second sealing lip 33 is located on the lower side of the first sealing lip 32, the stopper portion 34 is located between the first sealing lip 32 and the second sealing lip 33, and when the window glass 2 presses the second sealing lip 33 to deform beyond a preset value, the stopper portion 34 is adapted to abut against the second sealing lip 33 to restrict the relative position of the top of the window glass 2 and the first sealing lip 32.
The vehicle may be of a type commonly known in the art, and the above lifting process of the window glass 2 within the window glass mounting frame 1, and the mating relationship with the seal 3, have been described in detail hereinabove and will not be described in detail herein.
In this embodiment, the limiting portion 34 of the sealing member 3 can limit the size of the step formed between the outer side of the window glass 2 and the outer side of the first sealing lip 32 by the contact position of the window glass 2 and the first sealing lip 32, so that the limiting portion 34 can limit the deflection of the window glass 2 into the vehicle, reduce the size of the step formed between the outer side of the window glass 2 and the outer side of the first sealing lip 32, further reduce the windage coefficient of the vehicle door, reduce the windage applied to the vehicle door during the running process of the vehicle, and reduce the fuel consumption of the vehicle. In addition, reducing the step size formed on the outer side of the window glass 2 and the outer side of the first sealing lip 32 also improves the aesthetic appearance of the vehicle door.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
