Description
Technical Field
[0001] The embodiments of the present utility model relate to the technical field of automobiles, and particularly to a sealing strip for an automobile door. Background Art
[0002] Automobiles are a commonly used means of transportation and have entered ordinary households.
[0003] A sealing strip is provided on the door frame sheet metal of the rear door of the automobile near the front door. When the front door of the automobile is closed, it abuts against the sealing strip of the rear door to seal the vehicle body. In order to facilitate the smooth installation and use of the strip, the strip at the waistline of the automobile is made of soft rubber.
[0004] The inventor of the present application found that for the existing sealing strip used for the rear door of an automobile, the soft rubber at the waistline has relatively low rigidity. When the front door of the automobile is closed, the soft rubber at the waistline is squeezed and contracts inward, causing the base of the soft rubber to warp, forming a gap between the strip and the rear door, resulting in poor airtightness of the vehicle. When the vehicle is running, it will cause relatively large noise. When it rains, rainwater will enter the vehicle body from the gap, and the gap also affects the overall aesthetics of the vehicle body. Summary of the Utility Model
[0005] The purpose of the present utility model is to provide a sealing strip for an automobile door to solve the problems in the above background art.
[0006] The embodiments of the present utility model provide a sealing strip for an automobile door, including: a cross-section segment and a soft rubber segment;
[0007] The soft rubber segment is located in the middle of the sealing strip, and both ends of the soft rubber segment are respectively connected to the cross-section segment;
[0008] The soft rubber segment includes: a base portion and a sealing lip portion;
[0009] The sealing lip portion is arc-shaped, connected to the base portion, and an acute angle is formed between the sealing lip portion and the base portion;
[0010] The thickness of the base portion is greater than the thickness of the sealing lip portion;
[0011] The sealing strip is arranged on the rear door of the automobile, the soft rubber segment is located at the waistline of the automobile door, the base portion is used for fixing on the door frame sheet metal, and the sealing lip portion is used for abutting against the front door of the automobile.

[0031] The technical solution of the present utility model will be described in detail below with specific embodiments. The following several specific embodiments can be combined with each other, and for the same or similar concepts or processes, they may not be repeated in some embodiments.
[0032] As described in the background art of this application, a sealing strip is provided on the door frame sheet metal of the rear door of the vehicle near the front door. When the front door of the vehicle is closed, it abuts against the sealing strip of the rear door to seal the vehicle body. In order to ensure the smooth installation and use of the strip, the strip at the vehicle waistline is made of soft rubber.
[0033] The inventor of this application found that, as Figure 1 shown, for the existing sealing strip used for the rear door of the vehicle, the soft rubber at the door waistline 230 has relatively low rigidity. When the front door 220 is closed, the soft rubber at the waistline is squeezed and contracts inward, causing the base of the soft rubber to warp, forming a gap between the strip and the rear door 210, resulting in poor airtightness of the vehicle. When the vehicle is running, it will cause relatively loud noise, and when it rains, rainwater will enter the vehicle body from the gap, and the gap also affects the overall aesthetics of the vehicle body.
[0034] In order to solve the above problems, the inventor of this application proposed the technical solution of this application, and the specific embodiments are as follows:
[0035] Figure 2 It is a schematic diagram of the assembly position of the sealing strip in the embodiment of the present utility model, Figure 3 It is a schematic diagram of the assembly of the sealing strip in the embodiment of the present utility model, Figure 4 In the embodiment of the present utility model Figure 3 The schematic cross-sectional view taken along the line A-A in Figure 5 It is a schematic diagram of the state of the sealing strip when the front door is closed in the embodiment of the present utility model.
[0036] As Figures 2 to 5 shown, the sealing strip for the vehicle door in this embodiment includes: a cross-section segment 11 and a soft rubber segment 12.
[0037] The soft rubber segment 12 is located at the middle position of the sealing strip 1. The two ends of the soft rubber segment 12 are respectively connected to the cross-section segment 11 to form an integral sealing strip 1.
[0038] The soft rubber segment 12 includes: a base portion 121 and a sealing lip portion 122.
[0039] The sealing lip portion 122 is arc-shaped. One end of the sealing lip portion 122 is connected to one end of the base portion 121, and the other end of the sealing lip portion 122 extends outward. An acute angle is formed between the sealing lip portion 122 and the base portion 121.
[0040] The thickness of the base portion 121 of the soft rubber section 12 is greater than the thickness of the sealing lip portion 122.
[0041] In this embodiment, as Figure 3 shown, the sealing strip 1 is arranged on the rear door 210 of the vehicle and fixed on the door frame sheet metal near the front door 220. After the sealing strip 1 is installed, the soft rubber section 12 of the sealing strip 1 is located at the waist line 230 of the door, and the base portion 121 of the soft rubber section 12 is fixed on the door frame sheet metal of the rear door 210.
[0042] As Figure 4 、 Figure 5 shown, when the front door 220 of the vehicle is closed, it abuts against and presses the sealing lip portion 122. Since the thickness of the base portion 121 is larger, the rigidity and strength are increased. When the sealing lip portion 122 is pressed, the base portion 121 will not warp and still remains in contact with the rear door, making the vehicle body more sealed.
[0043] It is not difficult to find from the above content that for the sealing strip for vehicle doors in this embodiment, by providing a cross-section section and a soft rubber section, the two ends of the soft rubber section are respectively connected to the cross-section section. The soft rubber section includes: a base portion and a sealing lip portion. The sealing lip portion is arc-shaped and forms an acute angle with the base portion. The thickness of the base portion is greater than the thickness of the sealing lip portion. The sealing strip for vehicle doors in this embodiment is arranged on the door frame sheet metal of the rear door of the vehicle. The soft rubber section of the sealing strip is located at the waist line of the door, and the base portion is fixed on the door frame sheet metal. When the front door of the vehicle is closed, it contacts and presses the sealing lip portion. Since the thickness of the base portion is larger, the rigidity and strength of the base portion are increased. When the sealing lip portion is pressed by the front door, the base portion will not deform and warp, and still remains in contact with the door sheet metal, ensuring the airtightness of the door and making the vehicle as a whole more beautiful.
[0044] Optionally, for the sealing strip for vehicle doors in this embodiment, the soft rubber section 12 is provided with a groove 1201 at the connection between the sealing lip portion 122 and the base portion 121, and a thinner area section is formed at the end of the base portion 121 through the groove 1201. When the front door 220 of the vehicle is closed and contacts and presses the sealing lip portion 122, the soft rubber section 12 forms a bending deformation at the groove 1201 (the connection between the sealing lip portion and the base portion), so that the base portion 121 is more unlikely to warp and remains in contact with the door frame sheet metal of the rear door of the vehicle, ensuring the airtightness of the vehicle body.
[0045] Furthermore, for the sealing strip for vehicle doors in this embodiment, the groove 1201 is arranged inside the connection between the sealing lip portion 122 and the base portion 121, that is, the groove 1201 is arranged at the acute angle between the sealing lip portion 122 and the base portion 121.
[0046] Furthermore, for the sealing strip for vehicle doors in this embodiment, the cross-section of the groove 1201 is arc-shaped.
[0047] Furthermore, for the sealing strip for vehicle doors in this embodiment, the thickness of the base portion 121 is twice the thickness of the thinnest part of the groove 1201.
[0048] Optionally, for the sealing strip for vehicle doors in this embodiment, an arc-shaped protrusion 1221 is provided at the end of the sealing lip portion 122 close to the base portion 121, and the arc-shaped protrusion 1221 abuts against the sheet metal of the rear door frame, making the vehicle body more sealed.
[0049] Optionally, as Figure 3 shown, for the sealing strip for vehicle doors in this embodiment, a plurality of buckles 13 are provided at intervals on the soft rubber section 12 of the sealing strip 1, and the sealing strip is fixed in the card slot of the door frame sheet metal through the buckles 13, which facilitates the installation and fixation of the soft rubber section.
[0050] Optionally, for the sealing strip for vehicle doors in this embodiment, a plurality of buckles are also provided at intervals on the cross-section section 11 of the sealing strip 1, which facilitates the installation and fixation of the cross-section section when it is on the vehicle door sheet metal.
