Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and in particular to a vehicle door sealing structure. The utility model also relates to a vehicle provided with the vehicle door sealing structure. Background Art

[0002] In modern automobile design, the treatment of door seams has an important impact on the appearance, sealing, and dust and water resistance of the vehicle. Generally speaking, the treatment of door seams can be divided into two situations: one is the seam that cannot be directly observed from the appearance. This seam is usually designed at the bottom of the door. Due to the existence of door dust strips, its location is sometimes on the side wall, and sometimes on the side wall outer panel. This type of dust strip can effectively prevent dust and debris from entering during the vehicle's driving, thereby keeping the interior of the vehicle clean.

[0003] The other type is the seam that is clearly visible from the outside, which mainly exists between the side panels or trim panels. The existence of this seam allows dust to enter through the gap and then accumulate on the trim panel or side panel, affecting the appearance and cleanliness of the vehicle. In order to deal with this situation, dust strips are usually designed on the doors. These dust strips are connected to the door inner panel by snapping, forming a barrier to prevent dust from entering between the side trim panel and the door gap.

[0004] However, the current dust strip design has its lip on the same side as the buckle. When the door is closed, the long lip of the dust strip will bear a large force, resulting in uneven force on the product itself. This uneven force will cause the sealing strip on the side without the lip to separate from the sheet metal, causing the sealing strip to curl, affecting the sealing performance and service life of the dust strip. Utility Model Content

[0005] In view of this, the utility model aims to provide a vehicle door sealing structure to help ensure the sealing effect of the bottom of the vehicle door.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] A vehicle door sealing structure comprises a dustproof strip arranged at the bottom of the vehicle door;

[0008] The dust strip comprises a main body connected to the vehicle door, and a first lip and a second lip connected to the main body;

[0009] From the length direction of the dustproof strip, the first lip edge and the second lip edge are respectively arranged at two opposite sides of the main body portion, and a weakened structure that is easy to bend is provided at the root position where the first lip edge is connected to the main body portion;

[0010] The first lip abuts against the vehicle body side when the vehicle door is closed, and the second lip abuts against the bottom edge of the vehicle door.

[0011] Furthermore, the main body is connected to the vehicle door via a snap-fit ​​structure.

[0012] Furthermore, the snap-fit ​​structure includes a snap-fit ​​provided on the main body portion, and a snap-fit ​​hole provided on the vehicle door, and the snap-fit ​​is snap-fitted in the snap-fit ​​hole.

[0013] Furthermore, the clamping structure is a plurality of structures arranged at intervals along the length direction of the dustproof strip; and / or,

[0014] The buckle is made of PP material.

[0015] Furthermore, a third lip abutting against the vehicle door is provided on the main body portion, and viewed from the length direction of the dust strip, the third lip and the first lip are located on the same side of the main body portion.

[0016] Further, the interference amount between the second lip and the vehicle door, and the interference amount between the third lip and the vehicle door are not less than 0.3 mm; and / or,

[0017] When the first lip edge abuts against the vehicle body side, the interference amount between the two is not less than 7 mm.

[0018] Further, the weakening structure comprises a weakening groove provided at the root of the first lip; and / or,

[0019] A coating is provided on the side of the first lip edge abutting against the vehicle body side, the coating has a smooth outer surface, and the coating abuts against the vehicle body side.

[0020] Further, the angle formed between the second lip and the main body is an obtuse angle; or,

[0021] When the vehicle door is closed, the angle formed between the first lip and the main body is an acute angle, and the angle formed between the second lip and the main body is an obtuse angle.

[0022] Furthermore, the dustproof strip is made of EPDM material.

[0023] Compared with the prior art, the utility model has the following advantages:

[0024] With the vehicle door sealing structure described in the utility model, when the vehicle door is closed, the bottom of the vehicle door abuts against the first lip edge, and the first lip edge is easily bent due to the existence of the easily-bending weakened structure, so that the first lip edge abuts against the vehicle body side panel, and at the same time the second lip edge abuts against the bottom edge of the vehicle door, so that the vehicle door and the vehicle body side panel are sealed by the sealing strip. When the vehicle door is closed, the force applied to the first lip edge when it bends due to the force can be shared to both sides of the weakened structure, so that the dust strip itself is evenly stressed, which can avoid the problem of the dust strip edge warping, and is beneficial to ensuring the sealing effect of the bottom of the vehicle door.

[0025] The dust strip is assembled on the vehicle door by a snap-on connection, which is easy to install. The snap-on structure makes the dust strip easy to disassemble and replace, and the structure is simple, which is conducive to design implementation.

[0026] The clamping structure using the buckle and the clamping hole can ensure the stability of the connection between the dust strip and the door. It has a simple structure, is easy to process and install, is convenient for daily maintenance, and is conducive to design implementation.

[0027] Multiple snap-on structures ensure that the dust strip is firmly connected to the door, ensuring the stability of the dust strip during daily use. The buckle is made of PP material, which is easy to process and manufacture, and has the characteristics of being lightweight, which is conducive to the lightweight design of the vehicle.

[0028] The provision of the third lip enables the dust strip to fit the vehicle door after being assembled on the vehicle door, thereby better improving the sealing effect between the dust strip and the vehicle door, and the structure is simple, which is conducive to design implementation.

[0029] The interference amount between the second lip and the third lip and the door is not less than 0.3mm, so that when the dust strip is installed on the door, it can be squeezed and deformed by the door to fit on the door due to the interference amount, so that the dust strip can better fit on the door due to the deformation caused by squeezing, which is beneficial to ensure the sealing effect of the dust strip. The interference amount between the first lip and the body side is not less than 7mm, so that after the door is closed, when the first lip is squeezed and bent by the body side to abut on the body side, it can better fit on the body side due to the interference amount, which is beneficial to ensure the sealing effect of the dust strip.

[0030] The weakened groove arranged at the root of the first lip allows the first lip to bend from the root connected to the main part, which is conducive to design implementation. The setting form of the weakened groove is convenient for the processing and manufacturing of the dust strip, and when the first lip is bent by force, the force on the first lip can be shared from the weakened groove at the root to the main part and the first lip, which is conducive to ensuring the balanced force of the dust strip, preventing the problem of warping caused by uneven force, and ensuring the sealing effect of the bottom of the door. The coating is used to make the side of the first lip that abuts the body side smooth, which can prevent the friction noise between the first lip and the body side during the door closing process and driving process, which is conducive to design implementation.

[0031] The included angle formed between the second lip and the main part is an obtuse angle, which can ensure the sealing between the dust strip and the door. When the door is closed, the included angle between the first lip and the main part is an acute angle, which can make full use of the deformation of the lip to ensure the position accuracy when the door is closed and the sealing between the door and the side wall of the vehicle body.

[0032] The EPDM material has good elasticity and flexibility, which is conducive to the deformation and processing of the dustproof strip. It also has good water resistance and corrosion resistance, which is conducive to long-term use, helps to improve the service life of the dustproof strip, and is conducive to design implementation.

[0033] Another object of the present invention is to provide a vehicle, wherein the vehicle is provided with the door sealing structure as described above.

[0056] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0057] Embodiment 1

[0058] The present embodiment relates to a vehicle door sealing structure, which can ensure that the dust strip itself is subjected to balanced force when the vehicle door is closed, thereby avoiding the problem of the dust strip warping and ensuring the sealing effect of the bottom of the vehicle door.

[0059] In terms of overall structure, combined Figures 1 to 8 As shown, the vehicle door sealing structure in this embodiment includes a dust strip 2 arranged at the bottom of the vehicle door 1. The dust strip 2 includes a main body 201 connected to the vehicle door 1, and a first lip 202 and a second lip 203 connected to the main body 201.

[0060] From the length direction of the dust strip 2, the first lip 202 and the second lip 203 are arranged at two opposite sides of the main part 201, and a weakened structure 204 that is easy to bend is arranged at the root position where the first lip 202 is connected to the main part 201. The first lip 202 abuts against the body side 3 when the vehicle body is closed, and the second lip 203 abuts against the bottom edge of the door 1.

[0061] As configured above, the door sealing structure in this embodiment has the bottom of the door 1 abutted against the first lip 202 when the door 1 is closed. The first lip 202 is easily bent due to the presence of the easily-bending weakening structure 204, so that the first lip 202 abuts against the body side panel 3. At the same time, the second lip 203 abuts against the bottom edge of the door 1, so that the door 1 and the body side panel 3 are sealed by the sealing strip. When the door 1 is closed, the force applied to the first lip 202 when it bends due to the force can be shared on both sides of the weakening structure 204, so that the dust strip 2 itself is evenly stressed, which can avoid the problem of the dust strip 2 warping, and is beneficial to ensuring the sealing effect of the bottom of the door 1.

[0062] In order to improve the service life of the dustproof strip 2, the dustproof strip 2 in the present embodiment can be made of EPDM (EthylenePropylene Diene Monomer, ethylene propylene diene monomer) material. The EPDM material has good elasticity and flexibility, which is conducive to the deformation and processing of the dustproof strip 2, and has good water resistance and corrosion resistance, which is conducive to long-term use, helps to improve the service life of the dustproof strip 2, and is conducive to design implementation.

[0063] Combination Figure 7 and Figure 8 As shown, the main body 201 of the dustproof strip 2 in this embodiment has a cavity s, and the arrangement of the cavity s facilitates the assembly of the snap-fit ​​structure 4 .

[0064] In order to facilitate the connection between the dust strip 2 and the door 1, Figures 4 to 7 As shown, the main part 201 in this embodiment is connected to the vehicle door 1 through a snap-on structure 4, and the dust strip 2 is assembled on the vehicle door 1 by a snap-on connection method, which is easy to install. The snap-on structure 4 makes the dust strip 2 easy to disassemble and replace, and the structure is simple, which is conducive to design implementation.

[0065] Specifically, when the dust strip 2 is assembled on the vehicle door 1, the clip structure 4 is located at the top of the dust strip 2, and the clip structure 4 is not located on the same side as the first lip 202 and the second lip 203, so that when the dust strip 2 is assembled on the vehicle door 1 through the clip structure 4, the clip structure 4 will not affect the sealing effect of the dust strip 2.

[0066] In order to facilitate the disassembly of the dust strip 2 and the vehicle door 1, the snap-fit ​​structure 4 in this embodiment includes a snap 401 provided on the main part 201, and a snap hole 402 provided on the vehicle door 1. The snap 401 is snapped into the snap hole 402. The snap structure 4 in which the snap 401 cooperates with the snap hole 402 can ensure the stability of the connection between the dust strip 2 and the vehicle door 1. It has a simple structure, is easy to process and install, is convenient for daily maintenance, and is conducive to design implementation.

[0067] Specifically, the buckle 401 in this embodiment can be, for example, the buckle 401 commonly used in the bottom sealing strip of the existing vehicle door 1. The buckle 401 is assembled on the main part 201 of the dust strip 2, and the dust strip 2 is assembled on the vehicle door 1 through the snap-in hole 402 set on the vehicle door 1. This can reduce the need to open a new installation position on the vehicle door 1 due to changing the structure of the dust strip 2, which is beneficial to ensuring the applicability of the dust strip 2 and facilitating design implementation.

[0068] In order to ensure the connection stability of the clip-on structure 4, the clip-on structure 4 in this embodiment is arranged in a plurality at intervals along the length direction of the dust strip 2. The plurality of clip-on structures 4 ensures the connection between the dust strip 2 and the vehicle door 1 is firm, and can balance the force connecting the dust strip 2 and the vehicle door 1, thereby ensuring the connection stability of the dust strip 2 during daily use.

[0069] In order to facilitate the processing and manufacturing of the buckle 401, the buckle 401 is made of PP (Polypropylene) material. The buckle 401 made of PP material is easy to process and manufacture, and has the characteristics of being lightweight, which is conducive to the lightweight design of the vehicle.

[0070] Combination Figure 5 As shown, in this embodiment, a first lip edge 202 is provided on the main body 201 extending outwardly along the length direction of the main body 201, and the first lip edge 202 can abut against the body side panel 3 when the vehicle door 1 is closed. The first lip edge 202 can maintain a normal state under normal conditions. After the vehicle door 1 is closed, the first lip edge 202 abuts against the body side panel 3. Due to the setting of the easily bendable weakening structure 204 provided at the root of the first lip edge 202, the first lip edge 202 can be blocked and bent by the body side panel 3, and because the first lip edge 202 is blocked and bent by the body side panel 3, the part of the first lip edge 202 abutting against the body side panel 3 can be tightly fitted on the body side panel 3, which is beneficial to improve the sealing effect between the dust strip 2 and the body side panel 3.

[0071] In order to facilitate the sliding of the first lip edge 202 when it abuts against the body side panel 3, a coating is provided on the side of the first lip edge 202 abutting against the body side panel 3 in this embodiment. The coating has a smooth outer surface and abuts against the body side panel 3. The coating is used to make the side of the first lip edge 202 abutting against the body side panel 3 smooth, which can prevent abnormal friction noise between the first lip edge 202 and the body side panel 3 during the closing process of the door 1 and driving, and is conducive to design implementation.

[0072] In order to facilitate the bending of the first lip 202 and ensure the connection strength of the first lip 202, Figures 5 to 8 As shown, the weakening structure 204 in this embodiment includes a weakening groove arranged at the root of the first lip 202. The weakening groove arranged at the root of the first lip 202 allows the first lip 202 to bend from the root connected to the main part 201, which is beneficial to design implementation. The setting of the weakening groove is convenient for the processing and manufacturing of the dust strip 2, and when the first lip 202 is bent under force, the force applied to the first lip 202 can be shared by the main part 201 and the first lip 202 from the weakening groove at the root, which is beneficial to ensuring that the dust strip 2 is subjected to balanced force, preventing it from warping due to uneven force, and ensuring the sealing effect of the bottom of the vehicle door 1.

[0073] Specifically, the first lip 202 and the second lip 203 in the present embodiment are arranged on both sides of the main body 201 from the length direction of the main body 201, and the first lip 202 and the second lip 203 are connected by the main body 201, which effectively reduces the influence of the bending deformation of the first lip 202 when the door 1 is closed on the second lip 203, and the force applied to the first lip 201 is shared by the second lip 203 and the main body 201, thereby reducing the damage to the dust strip 2 caused by the force when the door is closed, and avoiding the poor sealing caused by the uneven force on the dust strip 2 and the warping, thereby improving the sealing effect of the dust strip 2.

[0074] In some embodiments, in order to improve the sealing between the dust strip 2 and the vehicle door 1, the angle formed between the second lip edge 203 and the main body 201 can be an obtuse angle in this embodiment, thereby ensuring the sealing between the dust strip 2 and the vehicle door 1.

[0075] In other embodiments, in order to ensure the position accuracy of the vehicle door 1 when it is closed, the present embodiment can make the angle formed between the first lip 202 and the main body 201 an acute angle when the vehicle door 1 is closed, and at the same time, the angle formed between the second lip 203 and the main body 201 is an obtuse angle. In this way, in addition to ensuring the sealing between the dust strip 2 and the vehicle door 1, the acute angle between the first lip 202 and the main body 201 when the vehicle door 1 is closed can utilize the full deformation of the lip to ensure the position accuracy of the vehicle door 1 when it is closed and ensure the sealing between the vehicle door 1 and the vehicle body side 3.

[0076] It should be noted that, combined with Figure 2 and Figure 8 As shown, the main part 201 of the door sealing structure in this embodiment is assembled on the door 1, and the first lip 202 and the second lip 203 are respectively abutted against the body side 3 and the door 1. When the door 1 is closed, dust can only enter the space t formed by the first lip 202, the second lip 203 and the main part 201, thereby ensuring the sealing effect of the bottom of the door 1 and facilitating the cleaning of dust on the dust strip 2.

[0077] In order to improve the connection effect between the dust strip 2 and the vehicle door 1, a third lip 205 abutting against the vehicle door 1 is provided on the main body 201 in this embodiment, and from the length direction of the dust strip 2, the third lip 205 and the second lip 203 are located on the same side of the main body 201. The setting of the third lip 205 enables the dust strip 2 to fit the vehicle door 1 after being assembled on the vehicle door 1, thereby better improving the sealing effect between the dust strip 2 and the vehicle door 1, and the structure is simple, which is conducive to design implementation.

[0078] Specifically, the third lip 205 extends outward from the edge of the main body 201 abutting against the vehicle door 1 . When the dust strip 2 is assembled on the vehicle door 1 , the third lip 205 can seal the gap between the dust strip 2 and the vehicle door 1 .

[0079] In order to improve the sealing effect between the first lip 202, the second lip 203 and the third lip 205 and the vehicle door 1 and the body side panel 3, when the first lip 202 and the body side panel 3 in this embodiment are in contact, the interference amount between the two is not less than 7mm, and can be, for example, 7mm, 7.5mm, or 8mm, etc., and the interference amount between the second lip 203 and the third lip 205 and the vehicle door 1 is not less than 0.3mm, and can be, for example, 0.3mm, 0.4mm or 0.5mm, etc.

[0080] Specifically, the sealing between the first lip 202 and the body side panel 3 is achieved when the first lip 202 is bent and deformed and abuts against the body side panel 3 after the door 1 is closed. Therefore, the interference amount of the first lip 202 must be no less than the gap between the door 1 and the body side panel 3 after the door 1 is closed, and the interference amount of the first lip 202 abutting against the body side panel 3 is no less than 7 mm. After the door is closed, the first lip 202 is squeezed and bent by the body side panel 3 and abuts against the body side panel 3. Due to the existence of the interference amount, the first lip 202 can better fit on the body side panel 3, which is beneficial to ensuring the sealing effect of the dust strip 2.

[0081] The second lip 203 and the third lip 205 are both in contact with the vehicle door 1 after the dust strip 2 is assembled on the vehicle door 1. Therefore, the interference between the second lip 203 and the third lip 205 only needs to be sufficient to allow the dust strip 2 to be slightly deformed when assembled on the vehicle door 1 to improve the sealing effect. The interference between the second lip 203 and the third lip 205 and the vehicle door 1 is not less than 0.3mm, so that when the dust strip 2 is assembled on the vehicle door 1, it can be squeezed and deformed by the vehicle door 1 to fit on the vehicle door 1 due to the existence of the interference, so that the dust strip 2 can better fit on the vehicle door 1 due to the deformation caused by being squeezed, which is beneficial to ensuring the sealing effect of the dust strip 2.

[0082] It should be noted that, combined with Figure 5 and Figure 6 As shown, the force on the first lip 202 comes from the body side 3. After the first lip 202 is subjected to force, part of the force will be distributed to the third lip 205 and the second lip 203. Figure 6 The direction of the middle arrow increases the interference force between the third lip 205, the second lip 203 and the door 1, and further reduces the force of the vehicle body side panel 3 on the first lip 202, thereby achieving a force balance state and preventing the dust strip 2 from tilting and causing sealing failure or deformation of the entire dust strip 2.

[0083] In this embodiment, the main body 201 of the dust strip 2 has a cavity s, which can not only facilitate the assembly of the snap-fit ​​structure 4, but also play a certain buffering role when the door 1 is closed, thereby dispersing the force acting on the dust strip 2 when the door 1 is closed, and the existence of the cavity s can reduce noise to a certain extent, forming a similar effect of a resonant cavity. The first lip 202 can abut against the body side 3 when the door 1 is closed, and because the weakened groove is set at the root of the first lip 202 connected to the main body, it can be easily bent. In the process of closing the door 1, the end of the first lip 202 abuts against the body side 3. As the closing stroke of the door 1 approaches the end, the end of the first lip 202 slides on the body side 3. At the end of the closing stroke of the door 1, the side of the first lip 202 abuts against the body side 3, thereby ensuring the sealing effect between the dust strip 2 and the body side 3.

[0084] After the dust strip 2 is assembled on the vehicle door 1, the second lip edge 203 and the third lip edge 205 are both in contact with the vehicle door 1, so as to seal the connection between the dust strip 2 and the vehicle door 1, and prevent dust from entering the vehicle door 1 from the assembly position of the dust strip 2, thereby affecting the use effect of the dust strip 2. In addition, due to the existence of the interference amount, there are forces between the first lip edge 202, the second lip edge 203 and the third lip edge 205 and the vehicle door 1 and the vehicle body side 3, respectively, so as to achieve a certain waterproof sealing effect.

[0085] The sealing effect of the vehicle door 1 in this embodiment is achieved due to the optimization of the structure of the dust strip 2. When the vehicle door 1 is closed, the force on the dust strip 2 can be balanced, avoiding the problem of the dust strip 2 warping, which is beneficial to ensuring the sealing effect of the bottom of the vehicle door 1.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
