[0038] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0039] The first embodiment of the utility model provides a door gap sealing strip, such as Figure 1 As shown, the door seal strip comprises:

[0040] The support body 1 has one end installed in the first gap 10 between the front windshield 100 and the vehicle body A-pillar 200, and the other end has a forked first support portion 11 and a second support portion 12, the first support portion 11 is connected to the front windshield 100, and the second support portion 12 is connected to the vehicle body A-pillar 200;

[0041] The sealing body includes a first sealing section 2 and a second sealing section 3, wherein one end of the first sealing section 2 is connected to the first supporting portion 11, and the other end of the first sealing section 2 is used to connect to the vehicle door 300 to seal the second gap 20 between the vehicle door 300 and the front windshield 100, and one end of the second sealing section 3 is connected to the second supporting portion 12, and the other end of the second sealing section 3 is used to connect to the vehicle door 300 to seal the third gap 30 between the vehicle door 300 and the A-pillar 200 of the vehicle body.

[0042] There is a first gap 10 between the front windshield 100 and the A-pillar 200 of the vehicle body, a second gap 20 between the front windshield 100 and the door 300, and a third gap 30 between the door 300 and the A-pillar 200 of the vehicle body. The door gap sealing strip seals the above three gaps respectively. Specifically, the support body 1 includes a main body 13, which is installed in the first gap 10 to seal the front windshield 100 and the A-pillar 200 of the vehicle body; the first sealing section 2 of the sealing body seals the second gap 20; and the second sealing section 3 of the sealing body seals the third gap 30. Three sealing structures are set between the door 300, the front windshield 100 and the A-pillar 200 of the vehicle body to improve the sealing performance of the vehicle, thereby improving the NVH performance of the vehicle.

[0043] like Figure 2 As shown, the vehicle door 300 includes a vehicle door outer panel 301 and a vehicle door inner panel 302, a first sealing section 2 and a second sealing section 3 are arranged opposite to each other, one end of the first sealing section 2 is connected to the end of the first supporting portion 11, and the other end of the first sealing section 2 is connected to the vehicle door outer panel 301 of the vehicle door 300 along a first direction, one end of the second sealing section 3 is connected to the end of the second supporting portion 12, and the other end of the second sealing section 3 is connected to the vehicle door inner panel 302 of the vehicle door 300 along a second direction, and the first direction and the second direction are opposite. The first sealing section 2 and the second sealing section 3 extend toward the vehicle door 300 from two directions respectively, wherein the first sealing section 2 is connected to the vehicle door outer panel 301, and the second sealing section 3 is connected to the vehicle door inner panel 302, and when the vehicle door 300 is in the open and closed states, the sealing performance between the vehicle door 300 and the front windshield 100 and the vehicle door 300 and the A-pillar can be ensured, and the appearance of the whole vehicle can also be improved.

[0044] The door seal strip is directly connected to the front windshield 100, the A-pillar 200 of the vehicle body and the door 300, and does not require the assistance of an additional mounting bracket, thereby reducing the weight of the structure and facilitating the lightweighting of the vehicle.

[0045] The first sealing section 2 and the second sealing section 3 are both arc-shaped sections. The first sealing section 2 can be configured to protrude along the first support portion 11 toward the vehicle door outer panel 301, or can be configured to be recessed along the end of the first support portion 11 toward the vehicle door outer panel 301. The second sealing section 3 can be configured to protrude along the end of the second support portion 12 toward the vehicle door inner panel 302, or can be configured to be recessed along the end of the first support portion 11 toward the vehicle door inner panel 302, thereby improving the sealing performance of the vehicle while taking into account the appearance of the vehicle in the closed state.

[0046] Furthermore, the hardness of the support body 1 is greater than that of the sealing body. The first sealing section 2 and the second sealing section 3 of the sealing body are both set as arc sections, and are connected to the door 300 with good elasticity. When the door 300 is closed, the first sealing section 2 and the second sealing section 3 are squeezed and deformed, and maintain an elastic outward state, forming a sealing effect on the contact surface between the door outer panel 301 and the first sealing section 2 and the contact surface between the door inner panel 302 and the second sealing section 3. The support body 1 has a higher hardness and a higher shape retention ability, and plays a supporting role for the overall structure of the door seal strip, so that the door seal strip structure has sufficient compression load, thereby achieving the effect of enhancing the sealing effect.

[0047] Exemplarily, the support body 1 is a dense colloid, and the first sealing section 2 and the second sealing section 3 are both sponge colloids.

[0048] The support body 1, the first sealing section 2 and the second sealing section 3 are integrally formed, which is easy to manufacture and can save installation time during the vehicle production process, thereby reducing vehicle development costs.

[0049] The end of the second sealing section 3 is provided with a support positioning lip 4 connected to the vehicle body A-pillar 200. Specifically, the support positioning lip 4 extends from the connection between the second sealing section 3 and the support body 1 toward the vehicle body A-pillar 200, and the second sealing section 3 is limited so that the support positioning lip 4 is still connected to the A-pillar in the door open state, maintaining the beautiful appearance of the vehicle.

[0050] like Figure 3As shown, a weakened opening 5 is provided at the bifurcation of the first support portion 11 and the second support portion 12, and the open ends of the weakened opening 5 are connected to the first support portion 11 and the second support portion 12 respectively. The first support portion 11 and the second support portion 12 extend outward from two different directions of the support portion respectively. Under normal conditions, the cross section of the support body 1 is in a "T" shape. The weakened opening 5 provided at the bifurcation of the first support portion 11 and the second support portion 12 is conducive to achieving deformation of the support body 1 with higher hardness during installation. Specifically, after the main body 13 of the support body 1 is installed in the first gap 10, the opening of the weakened opening 5 between the first support portion 11 and the second support portion 12 will become smaller, and the second support portion 12 will move in the direction close to the first support portion 11. After the second support portion 12 is deformed, there will be an elastic preload in this part, which prompts the second support portion 12 to fit closely with the A-pillar 200 of the vehicle body. At this time, the cross section of the support body 1 is in a "Y" shape. At this time, the ends of the first support portion 11 and the second support portion 12 at the opening position of the weakened opening 5 fit together, so that the first support portion 11 and the second support portion 12 support each other, which can ensure that the support positioning lip 4 is in close contact with the A-pillar and maintain the beautiful appearance of the vehicle.

[0051] like Figure 2 and Figure 3 As shown, a first stopper 14 is further provided on one side of the main body 13 connected to the front windshield 100, and a second stopper 101 is provided on the front windshield 100 to cooperate with the first stopper 14. When installing the door seal strip, the first stopper 14 on the main body 13 and the second stopper 101 on the front windshield 100 cooperate to prevent the door seal strip from falling out.

[0052] Specifically, the first limiting member 14 has an inclined surface on one side facing the first gap 10, and the side of the first limiting member 14 away from the first gap 10 is a limiting side, and the limiting side has a vertical first limiting surface 141, and the second limiting member 101 has a second limiting surface matching the first limiting surface 141. When installing the door gap sealing strip, the first limiting surface 141 matches the second limiting surface to achieve the limiting effect, and the inclined surface set on one side of the first limiting member 14 facilitates installation.

[0053] The main body 13 of the support body 1 is installed in the first gap 10, and a snap-on lip 6 is provided on one side of the main body 13 connected to the front windshield 100. The snap-on lip 6 and the first stopper 14 are arranged at intervals along the length direction of the main body 13, and the snap-on lip 6 is arranged near the end of the main body 13. The snap-on lip 6 extends toward the front windshield 100 and is connected to the glass surface of the front windshield 100. The snap-on lip 6 interferes with the glass surface of the front windshield 100, and the door gap sealing strip is snap-on and fixed, which is conducive to coping with the wind resistance pressure under the condition of high vehicle speed.

[0054] In some embodiments, there are multiple snap-on lips 6, and the multiple snap-on lips 6 are arranged at intervals along the length direction of the main body 13. Exemplarily, two snap-on lips 6 are arranged side by side along the length direction of the front windshield 100. While achieving installation and fixation, the snap-on lips 6 further improve the sealing performance between the front windshield 100 and the A-pillar 200 of the vehicle body.

[0055] An arc-shaped guide portion 7 is provided at one end of the support body 1 facing the first gap 10. Specifically, the arc-shaped guide portion 7 is provided at the side connected to the vehicle body A-pillar 200. When the main body 13 is installed in the first gap 10, the arc-shaped guide portion 7 plays a guiding role, which facilitates the installation of the main body 13. Specifically, through the elastic deformation of the clamping lip 6 and the extrusion of the arc-shaped guide portion 7 and the vehicle body A-pillar 200, the main body 13 is installed in the first gap 10 between the front windshield 100 and the A-pillar, thereby realizing the installation of the door gap sealing strip.

[0056] A water blocking lip 8 is provided between the first support portion 11 and one side of the front windshield 100. The water blocking lip 8 extends from the end of the first support portion 11 to the outside of the vehicle, and blocks the water flowing from the side of the front windshield 100 to the door 300, so that water does not enter the vehicle, thereby improving safety performance. At the same time, the water blocking lip 8 improves the appearance of the door seal strip structure.

[0057] In some embodiments, the distance of the water blocking lip 8 beyond the glass surface of the front windshield 100 is 3-5 mm. Specifically, the water flows along the front windshield 100 through the first sealing section 2 to the outside of the door 300, and will not enter the first gap 10 between the front windshield 100 and the A-pillar 200 of the vehicle body. In addition, the first sealing section 2 set in an arc shape also prevents rainwater from entering the second gap 20 between the front windshield 100 and the door 300, thereby preventing rainwater from entering the interior of the vehicle. Even if the water flows along the first sealing section 2 to enter between the door 300 and the A-pillar 200 of the vehicle body under special circumstances, the water flow will be blocked by the cavity surrounded by the first sealing section 2, the second sealing section 3, the door 300 and the second support portion 12. Multiple water blocking structures are provided to improve waterproof and water-conducting performance.

[0058] The support body 1 is provided with weight-reducing holes and / or shock-absorbing holes 9. The weight-reducing holes are used to reduce weight, and the shock-absorbing holes 9 are used to reduce shock during installation or vehicle driving. In this embodiment, in order to ensure the structural strength of the support body 1, only the weight-reducing holes or only the shock-absorbing holes 9 may be provided, or the weight-reducing holes and the shock-absorbing holes 9 may be the same opening. When the door seal strip structure is relatively large (for example, the main body 13 installed in the first gap is relatively long), both the weight-reducing holes and the shock-absorbing holes 9 may be provided. In a specific implementation, in order to facilitate the installation of the door seal strip, the structure of the door seal strip does not need to be set relatively large, therefore, only one through hole is provided in the main body 13, which is used as the weight-reducing hole and / or the shock-absorbing hole 9. The door seal strip can be applied to doors made of steel, aluminum alloy, carbon fiber, glass fiber, etc. and various materials, and has strong scalability.

[0059] The door seal strip can also be combined with other parts of the vehicle body through the joint angle of the seal strip to form a full-circle sealing structure, thereby improving the sealing performance of the entire vehicle. The door seal strip has good scalability and can be applied to the door seal of different models.
