[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Embodiment 1

[0036] The present embodiment relates to a vehicle door sealing structure, which is particularly suitable for frameless vehicle doors to solve the problem of water leakage in the glass groove 10 area of ​​existing vehicle doors, thereby improving the sealing and waterproof performance of the vehicle door.

[0037] In terms of overall structure, Figures 1 to 5 As shown, the vehicle door sealing structure of this embodiment includes a glass groove 10 provided on the vehicle door. In addition, a guide groove 11 is provided on the side of the glass groove 10 facing the vehicle door glass, and a guide portion located above the guide groove 11 and a drainage structure located below the guide portion are provided on the glass groove 10. The guide portion is used to guide the water flow to flow to the drainage structure along a preset path s, and the drainage structure is used to discharge the water flow flowing out of the guide portion. Among them, the preset path s and the drainage structure are both located on the side of the glass groove 10 facing the vehicle interior, and the preset path s is located on one side of the guide groove 11.

[0038] At this time, as set above, a guide portion can be provided above the guide groove 11 to guide the water flow to flow on one side of the guide groove 11, so as to change the water infiltration path and avoid the water flow to the joint of the door frame sealing strip, the glass groove 10 and the glass, that is, to avoid the two triangular hole structures on one water flow path. At the same time, by providing a drainage structure below the guide portion, the water flow that has infiltrated into the first seal can be discharged, thereby solving the problem of water leakage in the glass groove 10 area, thereby improving the sealing performance of the vehicle door.

[0039] It is worth mentioning that the guide groove 11 of this embodiment is used to clamp and support the glass, and can improve the stability of the glass lifting and lowering, and improve the sealing performance of the glass groove 10 when overlapping the glass. At the same time, the relevant structural parts not mentioned in the door sealing structure of this embodiment can refer to the various structures in the vehicle body structure well known to those skilled in the art. For example, in the prior art, the side end of the vehicle body (corresponding to the area of ​​the door opening) is usually provided with a glass upper sealing strip forming a first seal, the door opening of the vehicle body is usually provided with a door frame sealing strip forming a second seal, and the front corner area of ​​the door is usually provided with a glass groove 10, and the glass upper sealing strip, the door frame sealing strip and the glass groove 10 cooperate to clamp the glass and seal.

[0040] However, existing vehicle doors, especially frameless vehicle doors, will form a first triangular hole structure for water seepage at the joint of the glass felt groove 10, the sealing strip on the glass and the glass, and a second triangular hole structure for water seepage will be formed at the joint of the door frame sealing strip, the glass felt groove 10 and the glass. The two triangular hole structures are on the same water flow path. Such a structural design will cause water that seeps into the first and second seals to seep into the interior of the cockpit, affecting the customer's user experience.

[0041] The door sealing structure of this embodiment adopts the above design to achieve the external discharge of the infiltrated water through the cooperation of the guide part and the drainage structure, thereby solving the problem of water leakage at the door and improving the quality of the entire vehicle.

[0042] Based on the above overall introduction, in detail, in this embodiment, in specific implementation, the door sealing structure is preferably applicable to models with frameless doors, especially to front doors. Moreover, in this embodiment, the door sealing structure is mainly applied to the front door of a model with frameless doors as an example to introduce the relevant contents, and no further description will be given below.

[0043] In this embodiment, as a preferred implementation form, combined with Figure 2 and Figure 3As shown in , the guide part includes an opening 12 provided on the glass groove 10, and the opening 12 is connected to the guide groove 11. Here, the guide part includes the opening 12 provided on the glass groove 10, and the water flow guide function can be realized by improving the structure of the glass groove 10, without adding parts, which is conducive to the development and cost reduction of the glass groove 10.

[0044] Secondly, in this embodiment, as a preferred implementation form, the cross section of the opening 12 is U-shaped. It can be understood that the U-shaped cross section of the opening 12 has a simple structure and is conducive to the water flow that penetrates into the first seal to flow along the preset path s on one side of the guide groove 11 with the cooperation of the glass, avoiding the second triangular hole structure, thereby achieving a better waterproof effect.

[0045] Furthermore, in this embodiment, as a preferred configuration, continue to refer to Figure 2 and Figure 3 As shown, the drainage structure includes a water guide groove 13 provided on the side wall of the glass groove 10 facing the vehicle interior, and a drainage hole 14 provided at the end of the water guide groove 13 in the drainage direction. The main advantage of such a setting is that the structure is simple and the reliability is high, which is conducive to achieving a better drainage effect.

[0046] To expand, in this embodiment, as a preferred implementation form, the water guide groove 13 is set downwardly in the vertical direction of the whole vehicle. At this time, the water guide groove 13 is set downwardly in the vertical direction of the whole vehicle, which is more conducive to improving the smoothness of drainage.

[0047] In addition, in this embodiment, as a preferred implementation form, combined with Figure 2 and Figure 5 As shown, a clamping slot 151 for clamping with the car door is provided at the bottom of the glass groove 10, and the clamping slot 151 is located on the side wall of the glass groove 10 facing the inside of the car, and the clamping slot 151 is arranged close to the guide groove 11. The arrangement of the clamping slot 151 facilitates the convenient assembly of the glass groove 10 and the car door.

[0048] It is worth mentioning that in this embodiment, during the specific implementation, a protrusion 15 protruding toward the inside of the vehicle is provided on the side wall of the glass groove 10 facing the inside of the vehicle, and a slot 151 is formed on the protrusion 15 and penetrates the protrusion 15 along the front-to-rear direction of the entire vehicle, and an opening 12 of the slot 151 is set downward.

[0049] At the same time, in this embodiment, in order to make the glass groove 10 have a better installation effect, if necessary, it can also be as follows Figure 2 As shown, a mounting portion 16 is provided on the right side of the glass groove 10 (the side away from the guide groove 11), so that the mounting portion 16 cooperates with the card slot 151 to improve the installation stability of the glass groove 10. Specifically, for example Figure 4As shown in , a clamping column or the like that is clamped with the door sheet metal can be provided on the mounting portion 16. And, if necessary, the glass groove 10 of this embodiment can also be provided with a reinforcing rib or the like to enhance its own strength and ensure that it has sufficient supporting performance.

[0050] In addition, in this embodiment, as a preferred implementation form, still refer to Figure 5 As shown, the guide groove 11 is provided with lips 113 respectively abutting against the inner and outer walls of the door glass. It is understandable that by providing the lips 113 on the guide groove 11, it is helpful to ensure the lifting stability of the glass and improve the sealing of the overlap between the glass and the glass groove 10.

[0051] It is worth mentioning that the guide groove 11 of this embodiment has a first groove wall 111 and a second groove wall 112 arranged opposite to each other, and the second groove wall 112 is located on the outside of the first groove wall 111, that is, the lip 113 on the first groove wall 111 abuts against the inner wall of the door glass, and the lip 113 on the second groove wall 112 abuts against the outer wall of the door glass. When the door glass moves along the guide groove 11, the two lips 113 abut against the inner and outer walls of the door glass respectively, thereby improving the moving stability and sealing of the glass. Of course, if necessary, in this embodiment, according to the actual clamping and sealing requirements of the door glass, the lip 113 can also be set only on the first groove wall 111 or the second groove wall 112.

[0052] At the same time, the glass groove 10 of this embodiment is combined with Figure 1 and Figure 2 As shown, the guide groove 11 includes an upper section and a lower section, wherein Figure 2 The lower section of the guide groove 11 is not shown in the figure, and the glass groove 10 without the lower section of the guide groove 11 is generally triangular in structure. Figure 2 As shown in the figure, the bottom side of the triangular structure cooperates with the vehicle door, the guide groove 11 is formed on the vertical side of the triangular structure to facilitate cooperation with the glass, and the water guide groove 13 has a shape parallel to the hypotenuse of the triangular structure (that is, the water guide groove 13 extends forward along the front-rear direction of the whole vehicle and is tilted downward at the same time), and the drainage direction is from the top (that is, the starting end) to the bottom (that is, the end) of the water guide groove 13 in the up-down direction of the whole vehicle, and the drainage hole 14 is arranged at the lowest end of the water guide groove 13 to facilitate the drainage of water.

[0053] In addition, the drainage hole 14 passes through the glass felt groove 10 along the left-right direction of the entire vehicle, that is, in the thickness direction of the glass felt groove 10, and the drainage hole 14 is connected to the cavity inside the door. After the water is discharged into the cavity, it is discharged to the outside of the vehicle through the leakage hole designed at the bottom of the cavity, thereby solving the water leakage problem at the glass felt groove 10 of the door.

[0054] It can also be understood here that the opening 12 of the present embodiment is generally U-shaped when viewed downward along the vertical direction of the vehicle, which does not mean that it must be in the shape of the letter "U" in the strict sense, but has a certain shape trend that follows the hypotenuse of the glass groove 10 (the above-mentioned triangular structure).

[0055] Furthermore, when the existing glass groove 10 is not designed with the opening 12, the water that penetrates into the first seal will flow along the guide groove 11 and into the vehicle through the triangular hole at the joint of the door frame sealing strip, the glass groove 10 and the glass, thereby affecting the quality of the vehicle.

[0056] The vehicle door sealing structure of the present embodiment can change the water infiltration path by arranging a guide portion above the guide groove 11 to guide the water flow to flow on one side of the guide groove 11, thereby preventing the water flow from flowing to the joint of the door frame sealing strip, the glass groove 10 and the glass, that is, preventing the two triangular hole structures from being on the same water flow path. At the same time, by arranging a drainage structure below the guide portion, the water flow infiltrated into the first seal can be discharged, thereby solving the problem of water leakage in the glass groove 10 area, improving the sealing and waterproof performance of the vehicle door, and thus improving the quality of the entire vehicle.

[0057] Secondly, the cross section of the opening 12 is U-shaped, with a simple structure, and is conducive to the water flow that penetrates into the first seal to flow along the preset path on one side of the guide groove 11 with the cooperation of the glass, avoiding the second triangular hole structure, thereby achieving a better waterproof effect. The drainage structure is mainly composed of the water guide groove 13 and the drainage hole 14, and the water guide groove 13 is set upside down in the vertical direction of the whole vehicle, so that the structure is simple, the reliability is high, and it is more conducive to improving the smoothness of drainage, thereby improving the drainage effect. At the same time, the setting of the card slot 151 is conducive to improving the convenient assembly of the glass groove 10 and the car door. The lip edge 113 is set to ensure the lifting stability of the glass and improve the sealing of the overlap between the glass and the glass groove 10.

At the same time, also as a preferred implementation form, the vehicle door has a cavity connected to the drainage structure, and a water leakage hole arranged at the bottom of the cavity.

[0061] During specific implementation, relevant structural parts not mentioned in the vehicle door of this embodiment may refer to the vehicle door structure well known to technical personnel in this field, especially the various structures in the frameless vehicle door, for example, it may include a vehicle door inner panel and a vehicle door outer panel, and the cavity is arranged in the area enclosed by the vehicle door inner panel and the vehicle door outer panel, etc.

[0062] Secondly, the drainage hole 14 in the drainage structure of this embodiment is connected to the cavity, so that the water flow that penetrates into the first seal is first guided through the opening 12 and then flows into the water guide groove 13 along the preset path s. At this time, the water flow that flows into the water guide groove 13 flows into the cavity of the vehicle door through the drainage hole 14, and finally is discharged out of the vehicle door from the leakage hole, thereby preventing water from intruding into the vehicle, thereby improving the sealing of the entire vehicle, especially the sealing of vehicles with frameless doors.

[0063] In addition, this embodiment also relates to a vehicle, in which the above-mentioned vehicle door is provided.
