Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, specifically relating to a door sealing strip structure, a door, and a vehicle. Background Technology

[0002] In the current automotive industry, almost all models use a rounded transition at the corners where the door meets the body sheet metal, requiring a rounded bend at the corner. This type of rounded transition sealing strip has the following drawbacks:

[0003] (1) The arc transition bend will cause the internal bubble tube to deform to varying degrees, and the appearance will collapse, thus affecting the appearance quality; (2) The arc transition bend has a large volume and requires a large space, which will squeeze the space of the head position when the driver and passengers get on and off the vehicle. Utility Model Content

[0004] This utility model provides a door sealing strip structure, a door, and a vehicle, aiming to solve the problem that the arc transition bend will squeeze the internal foam tube, causing varying degrees of deformation and affecting the appearance quality. It also solves the problem that the arc transition bend occupies a large space and restricts the space for passengers to get in and out of the vehicle.

[0005] Firstly, to achieve the above objectives, the technical solution adopted by this utility model is as follows: a door sealing strip structure is provided, comprising: a first sealing strip and a second sealing strip, wherein one end of the first sealing strip has a first oblique end face; the end of the second sealing strip connected to the first sealing strip has a second oblique end face that is in contact with the first oblique end face; the first sealing strip and the second sealing strip are in contact with the second oblique end face through the first oblique end face; wherein the cross-sectional structure of the second sealing strip is the same as that of the first sealing strip.

[0006] In conjunction with the first aspect, in one feasible manner, the first sealing strip includes an integrally formed bubble tube, a snap-fit ​​groove, and a sealing lip. The snap-fit ​​groove is embedded with a U-shaped skeleton and snaps onto the door frame sheet metal. The bubble tube is exposed outside the snap-fit ​​groove, and the sealing lip is bent toward the door frame sheet metal.

[0007] In conjunction with the first aspect, in one feasible manner, the first sealing strip further includes a pull cord that is wrapped inside the sealing lip and connected to the inner side of the sealing lip.

[0008] In conjunction with the first aspect, in one feasible manner, the bubble tube is provided with a reinforcing rib on its inner side near the snap-fit ​​groove.

[0009] In conjunction with the first aspect, in one feasible manner, the inner surface of the bubble tube is further provided with a deformation notch to facilitate deformation of the bubble tube under pressure.

[0010] In conjunction with the first aspect, in one feasible manner, an anti-detachment lip is provided on the inner side of the snap-fit ​​groove away from the bubble tube, and the anti-detachment lip is inclined toward the bottom of the snap-fit ​​groove.

[0011] In conjunction with the first aspect, in one feasible manner, a shallow deformation groove is provided on the side of the anti-detachment lip facing the bottom of the snap-fit ​​groove to facilitate the deformation of the anti-detachment lip, and the cross-section of the shallow deformation groove is an arc-shaped curved surface.

[0012] In conjunction with the first aspect, in one feasible manner, the snap-fit ​​groove is provided with anti-detachment teeth on the inner side near the bubble tube, and the anti-detachment teeth are inclined toward the bottom of the snap-fit ​​groove.

[0013] Compared with the prior art, the door sealing strip structure provided by this utility model has the following advantages: (1) Compared with the sealing strip with arc transition bending, this application directly cuts the same inclined end face at the joint end of the two sealing strips with the same cross section. The inclined end faces of the two sealing strips are attached and can be firmly connected by heat vulcanization. This not only ensures the connection strength of the two sealing strips, but also does not require bending deformation when the two sealing strips are joined. Instead, they are joined in the same direction and will not bear downward deformation stress. This avoids the risk of appearance collapse due to stress deformation at the corner of the sealing strip and improves the appearance quality; (2) Compared with the door frame sealing strip with arc transition bending, this application directly cuts the same inclined end face at the joint end of the two sealing strips. In this application, the oblique end faces of the two sealing strips are directly connected to form a triangular apex structure. A small triangular space is formed at the existing arc transition bend position, which expands the space at the corner of the door frame, thereby increasing the space for the head position of the driver and passengers when getting in and out of the vehicle, and improving the passenger experience; (3) Compared with the sealing strip that requires an arc transition, this application only needs to set a groove along the actual application direction of the two sealing strips when connecting the two sealing strips. After the limit is set, the oblique end faces of the two are connected and heated for vulcanization. There is no need for a complicated corner mold. The connection between the two is simple and convenient, saving time and effort, and also reducing material consumption and cost.

[0014] Secondly, this utility model embodiment also provides a car door, which is provided with the aforementioned car door sealing strip structure.

[0015] The car door provided in this embodiment of the utility model can be directly cut at one end of the two sealing strips to form a triangular pointed structure, which can be joined together by simply cutting the beveled end face. The connection of the sealing strip does not require deformation or bending, so the appearance of the car door will not sag after installation, ensuring the appearance quality of the car door. It also expands the head space above the car door when passengers get in and out of the car, improving the riding experience of the driver and passengers, and reducing the manufacturing cost of the car door.

[0016] Thirdly, this utility model embodiment also provides a vehicle equipped with the aforementioned door.

[0017] The car door and vehicle provided in this embodiment of the utility model can be directly cut at one end of the two sealing strips to form a triangular pointed structure by fitting them together. The connection of the sealing strip does not require deformation or bending. Therefore, the appearance of the car door will not sag after installation, which ensures the appearance quality of the car door. It also expands the head space above the car door when passengers get in and out of the car, which can bring customers a differentiated perception, enhance the product's appeal and quality, and enhance the brand value of the whole vehicle.

Detailed Implementation

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Unless otherwise expressly defined, the use of terms such as "first," "second," or "third" in the claims, description, and drawings of this utility model is for distinguishing different objects and not for describing a specific order.

[0030] In the claims, description, and accompanying drawings of this utility model, the terms "upper" and "lower" correspond to the vertical direction of the vehicle body; the terms "front" and "rear" correspond to the front-rear direction of the vehicle body; and the terms "left" and "right" correspond to the left-right direction of the vehicle body.

These are merely for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the specific scope of protection of this invention.

[0031] Please refer to the following: Figures 1 to 8 The door sealing strip structure provided by this utility model will now be described. The door sealing strip structure includes: a first sealing strip 2 and a second sealing strip 3. One end of the first sealing strip 2 has a first beveled end face 8; the end of the second sealing strip 3 connected to the first sealing strip 2 has a second beveled end face that abuts against the first beveled end face 8; the first sealing strip 2 and the second sealing strip 3 are connected by the first beveled end face 8 and the second beveled end face; wherein the cross-sectional structure of the second sealing strip 3 is the same as that of the first sealing strip 2.

[0032] The door sealing strip structure provided by this utility model has the following advantages compared with the prior art:

[0033] (1) Compared with the arc transition sealing strip, this application directly cuts the same inclined end face at the joint end of the two sealing strips with the same cross section. The two sealing strips can be firmly connected by touching the inclined end face and heating and vulcanizing. This not only ensures the connection strength of the two sealing strips, but also does not require bending deformation when the two sealing strips are joined. Instead, they are joined in the same direction and will not bear downward deformation stress. This avoids the risk of appearance collapse due to stress deformation at the corner of the sealing strip and improves the appearance quality.

[0034] Moreover, this beveled end face forms a sharp corner structure at the corner of the sealing strip. Compared with the rounded transition bend of the sealing strip, the consistency of the product shape and after assembly is better guaranteed. It avoids the problem of the sealing strip tube 6 being concave in actual application, which is easy to occur when the sealing strip is rounded transition bend.

[0035] Combination Figure 1 Understandably, the vehicle's front door upper rear corner, rear door upper front corner, and rear upper rear corner all utilize this direct-joint sharp-angle structure. Taking the front door as an example, the first sealing strip 2 can be installed along the upper edge of the door frame, and the second sealing strip 3 can be installed as the rear sealing strip of the front door along the rear edge of the door frame. These two sealing strips should be directly joined at the upper rear corner of the front door. Both sealing strips are straight segments, and beveled at the same angle using a cutting device. Vulcanizing the connection with a vulcanizing device ensures both connection strength and aesthetics.

[0036] (2) Compared with the rounded transition bend at the corner of the door frame sealing strip, the two oblique cut ends of the sealing strip in this application are directly connected to form a triangular slant structure. A small triangular space is formed at the existing rounded transition bend position, which expands the space at the corner of the door frame, thereby increasing the space for the head of the driver and passengers when getting in and out of the vehicle and improving the passenger experience.

[0037] Taking the upper rear corner of the front door as an example, since the beveled ends of the two straight sealing strips are directly connected, there is no need to set an arc shape at the upper rear corner of the front door frame sheet metal 1. The sheet metal layout area can be reduced at the upper rear corner, thereby increasing the space for the head of the driver and passengers.

[0038] (3) Compared with the sealing strip with rounded transition at the corner, this application only needs to set the groove along the actual application direction of the two sealing strips when connecting the two sealing strips. After the limit is set, the oblique cut ends of the two can be connected and heated for vulcanization. There is no need for a complicated corner mold. The connection between the two is simple and convenient, saving time and effort, and also reducing material consumption and cost.

[0039] It should be noted that the cross-sections involved in this application refer to the cross-sectional shape formed along the direction perpendicular to the length of each sealing strip segment. The angle of the sharp corner formed after the two sealing strip segments are joined can be a right angle or 90±5°, see [reference needed]. Figure 1 .

[0040] Regarding the inclination angle of the beveled end faces, taking the first sealing strip 2 as an example, the angle between the first beveled end face 8 and the length direction of the first sealing strip 2 is 45±5°; similarly, the angle between the second beveled end face and the length direction of the second sealing strip 3 is also 45±5°. For example, when the corner of the door frame sheet metal is a right angle, the first sealing strip and the second sealing strip are connected perpendicularly. At this time, the inclination angle of both beveled end faces is 45°. Since the angle of the door frame sheet metal corner can also be less than 90°, such as 88°, or greater than 90°, such as 93°, it is also possible to directly connect the beveled end faces to form a sharp corner without the need for a rounded transition.

[0041] In some embodiments, see Figures 2 to 7 The first sealing strip 2 includes an integrally formed bubble tube 6, a snap-fit ​​groove 7, and a sealing lip 4. The snap-fit ​​groove 7 is embedded with a U-shaped skeleton 73. The snap-fit ​​groove 7 is snapped onto the door frame sheet metal stop 11. The bubble tube 6 is exposed on the outside of the snap-fit ​​groove 7. The sealing lip 4 is bent towards the inside of the door frame sheet metal 1.

[0042] Both the first sealing strip 2 and the second sealing strip 3 are installed by fitting them to the door frame sheet metal stop 11 via the snap-fit ​​groove 7. The boundary of the door frame sheet metal stop 11 restricts the sealing strip installation and prevents interference between the product and the door frame sheet metal 1 due to over-fitting. The bubble tube 6 is exposed outside the door frame. When the door is closed, it directly presses against the bubble tube 6 to achieve a seal after the door is closed. The sealing lip 4 can be understood as follows: when sealing strips are installed on all four sides of the door frame, the sealing lips 4 of each sealing strip on the four sides of the door frame form the smallest window of the door frame, that is, the edge of the sealing lip 4 constitutes the smallest boundary of the door frame.

[0043] It should be noted that since the cross-sectional shape of the second sealing strip 3 is the same as that of the first sealing strip 2, this application only describes the structure of the first sealing strip 2. The structure of the second sealing strip 3 is completely the same as that of the first sealing strip, except that its length is different. The construction of the beveled end faces of the two is also completely the same. Therefore, the structure of the second sealing strip is not described in the specification. Moreover, the construction of the beveled end faces is also completely the same. When the two sealing strips are joined at the corner, the bubble tubes 6 of the two sealing strips are joined together, the snap-fit ​​grooves 7 are joined together, and the sealing lips 4 are joined together.

[0044] In some embodiments, see Figure 3 and Figure 7As shown, the first sealing strip 2 also includes a pull rope 5, which is wrapped inside the sealing lip 4 and connected to the inner side of the sealing lip 4. The pull rope 5 is wrapped inside the sealing lip 4. The function of the pull rope 5 is based on the overall vehicle assembly. The sealing lip 4 overlaps the edge of the door interior trim. During assembly, the door frame strip is installed first, followed by the door interior trim. After the door interior trim is installed, it will press down the sealing lip 4. The pull rope 5 is used to pull out the sealing lip 4 so that it overlaps the door interior trim.

[0045] In some embodiments, see Figure 3 and Figure 7 As shown, a reinforcing rib 61 is provided on the inner side of the bubble tube 6 near the snap-fit ​​groove 7 to improve the deformation resistance of the bubble tube 6. Specifically, multiple reinforcing ribs 61 are integrally formed on the partition wall shared by the bubble tube 6 and the snap-fit ​​groove 7. The length of the reinforcing rib 61 is the same as the length of the bubble tube 6. The cross-sectional shape of the reinforcing rib 61 can be triangular, trapezoidal or semi-circular.

[0046] In some embodiments, see Figure 3 As shown, the inner surface of the bubble tube 6 is also provided with a deformation notch 62 to facilitate the deformation of the bubble tube 6 under pressure. The length direction of this deformation notch 62 is consistent with the length direction of the bubble tube 6 and is the same as the length of the bubble tube 6. Explained, since the bubble tube 6 is the main part that is subjected to compression deformation by the car door, it needs both good elastic deformation and good elastic recovery. During the frequent closing of the car door, the bubble tube 6 will inevitably crack due to fatigue deformation, affecting the service life of the sealing strip; therefore, this application provides a deformation notch 62 on the inner surface of the bubble tube 6 in advance, which can improve the situation of cracking due to fatigue deformation of the bubble tube 6.

[0047] In this application, two deformation notches 62 are symmetrically provided on the bubble tube 6. The deformation notches 62 are pre-set at the positions where the bubble tube 6 is prone to deformation and bending under pressure. The deformation notches are pre-set for the deformation of the bubble tube 6 under pressure, thereby eliminating stress concentration and avoiding the risk of fatigue cracks in other positions of the bubble tube.

[0048] In some embodiments, see Figure 3 As shown, an anti-detachment lip 71 is provided on the inner side of the snap-fit ​​groove 7 away from the bubble tube 6. The anti-detachment lip 71 is inclined towards the bottom of the snap-fit ​​groove 7. Since the snap-fit ​​groove 7 is embedded with a U-shaped skeleton 73 to maintain its structural shape and strength, the shape of the snap-fit ​​groove 7 is also U-shaped. When the snap-fit ​​groove 7 is snapped into the door frame sheet metal stop 11, it is necessary to ensure the firmness of the snap-fit. Therefore, this inclined anti-detachment lip 71 is provided. The anti-detachment lip 71 can tightly abut against the door frame sheet metal stop 11, which can prevent the sealing strip from slipping outward, improve the firmness of the sealing structure snap-fit, and also improve the sealing performance.

[0049] In some embodiments, see Figure 3 and Figure 7As shown, the anti-detachment lip 71 has a shallow deformation groove 711 on the side of the groove bottom facing the snap-fit ​​groove 7, which facilitates the deformation of the anti-detachment lip 71. The cross-section of the shallow deformation groove 711 is an arc-shaped curved surface. The shallow deformation groove 711 on the anti-detachment lip 71 has the same function as the deformation notch 62 in the bubble tube 6, which is to pre-set the stress deformation notch 62 to avoid the anti-detachment lip 71 from cracking due to fatigue deformation.

[0050] In some embodiments, see Figure 3 and Figure 7 As shown, anti-detachment teeth 72 are provided on the inner side of the snap-fit ​​groove 7 near the bubble tube 6, and the anti-detachment teeth 72 are inclined towards the bottom of the snap-fit ​​groove 7. This inclined anti-detachment tooth 72 allows it to tightly abut against the door frame sheet metal stop 11, preventing the sealing strip from slipping outwards. Multiple anti-detachment teeth 72 are provided within the snap-fit ​​groove 7, and the length direction of each anti-detachment tooth 72 is consistent with and the same as the length direction of the sealing strip. The cross-sectional shape of the anti-detachment tooth 72 can be triangular.

[0051] The anti-detachment teeth 72 and the anti-detachment lips 71 are tightly interfering and abutting against the door frame sheet metal 1 from the inner and outer sides of the door frame sheet metal stop 11, which greatly improves the tightness and firmness of the connection between the sealing strip and the door frame sheet metal 1.

[0052] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0053] Based on the same inventive concept, this application also provides a car door with the aforementioned car door sealing strip structure.

[0054] The car door provided in this embodiment of the utility model can be directly cut at one end of the two sealing strips to form a triangular pointed structure, which can be joined together by simply cutting the beveled end face. The connection of the sealing strip does not require deformation or bending, so the appearance of the car door will not sag after installation, ensuring the appearance quality of the car door. It also expands the head space above the car door when passengers get in and out of the car, improving the riding experience of the driver and passengers, and reducing the manufacturing cost of the car door.

[0055] Based on the same inventive concept, this utility model embodiment also provides a vehicle equipped with the aforementioned door.

[0056] The vehicle provided in this embodiment of the utility model, by adopting this two-section sealing strip obliquely cut and joined connection method, ensures the appearance quality of the car door; and expands the space above the car door for passengers to get in and out of the car, which can bring customers a differentiated perception, enhance the product's attractiveness and quality, improve the brand value of the whole vehicle, and also reduce the overall vehicle manufacturing cost.
