Description

Technical Field

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

[0002] As consumers have higher and higher requirements for the convenience and appearance of vehicles, they are paying more and more attention to the sealing of vehicle doors. In order to improve the sealing of the interior of the vehicle, the usual design will arrange sealing strips under or on the side of the vehicle door to prevent mud and water from entering the vehicle, sound insulation and noise reduction, and heat insulation.

[0003] The lower seal of the door is the key to preventing mud, water and dust from entering the threshold. At present, the lower seal of the vehicle door mostly adopts a closed bubble tube or lip seal strip structure, which is installed on the lower part of the side wall or the outer trim of the threshold. When the door is closed, the lower edge of the door or the outer trim of the door compresses the closed bubble tube or lip seal strip to seal the gap, thereby preventing mud and water from entering.

[0004] However, the threshold of the side panel is usually provided with a bending angle. If mud, water, dust and other debris enter the bending angle, it is difficult to actively discharge them. Existing sealing structures such as closed bubble tubes or lip seals are mainly suitable for vehicles with Y-direction (transverse direction of the vehicle) split seams at the bottom of the door. For vehicles with Z-direction (height direction of the vehicle) split seams at the bottom of the door, when the vehicle is driving, mud and water are thrown up by the wheels. Compared with vehicles with Y-direction split seams, mud and water are more likely to be thrown into the lower door seal of vehicles with Z-direction split seams. Because the conventional closed bubble tube or lip seal structure of the Z-direction split seam vehicle has the disadvantage of not being able to seal to the bending angle of the threshold, the bending angle of the threshold will be exposed, resulting in the accumulation of mud, water or dust at the outer rounded corner of the threshold outer panel. When the occupants get on and off the vehicle, it is difficult to avoid contact with the outer rounded corner of the threshold outer panel with their calves, and mud, water and dust will stain the legs of the passengers, affecting the quality of the vehicle. Utility Model Content

[0005] In view of this, the utility model aims to provide a vehicle door sealing component to improve the use quality of the vehicle.

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

[0007] A vehicle door sealing component is installed at the part where the vehicle door sheet metal and the outer rocker plate face each other, and the vehicle door sealing component includes: a sealing portion, including a sealing body, and a first lip edge; the sealing body is maintained on the vehicle door sheet metal along the length direction of the vehicle body, and the first lip edge is connected to the sealing body and extends toward the direction of the outer rocker plate; when the vehicle door is closed, the first lip edge is attached below the bending corner of the outer rocker plate.

[0008] Furthermore, when the vehicle door is in a closed state, the first lip is covered by the vehicle door outer panel.

[0009] Furthermore, the longitudinal section of the sealing body is constructed to be an arch shape that is buckled on the door sheet metal.

[0010] Furthermore, the door sealing component includes:

[0011] The mounting portion is received in a cavity between the sealing body and the door sheet metal to form a fixed connection between the sealing body and the door sheet metal.

[0012] Furthermore, the sealing body includes a basic sealing portion and a second lip edge connected along the height direction of the vehicle body; and the mounting portion is mounted on the free end of the basic sealing portion.

[0013] Furthermore, the mounting portion includes a supporting frame and a plurality of clamping portions;

[0014] The support frame is extended along the length direction of the vehicle body and is fixedly connected to the basic sealing part near the free end of the basic sealing part. A plurality of mounting holes adapted to the clamping parts are provided on the support frame, and the mounting holes are spaced apart along the extension direction of the support frame.

[0015] The clamping portion passes through the mounting hole from the inner side of the supporting frame so as to be clamped on the door sheet metal.

[0016] Furthermore, the plurality of mounting holes include long through holes distributed in the main body area of ​​the support frame, and positioning holes arranged near the edge of the support frame.

[0017] Furthermore, a weak portion is formed on the inner surface of the free end of the basic sealing portion; a folded edge is formed on the upper edge of the supporting frame, and the folded edge is abutted and fixedly connected to the weak portion.

[0018] Furthermore, the free end of the basic sealing portion has an extension that passes over the supporting frame and abuts against the door sheet metal.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] The sealing portion of the vehicle door sealing component described in the utility model is connected to the vehicle door sheet metal, and is in contact and sealed with the outer rocker plate through a first lip edge. The sealing position is lower than below the bending angle of the outer rocker plate. When the vehicle door is closed, the sealing portion can block the gap between the vehicle door and the outer rocker plate, so that external mud, water and dust are not easy to enter the bending angle of the outer rocker plate, which is beneficial to keeping the bending angle of the outer rocker plate clean and does not contaminate the legs of the occupants when getting on and off the vehicle, thereby improving the use quality of the vehicle.

[0021] Secondly, when the door is closed, the door outer panel can cover the first lip, making the lower part of the door smoother and more beautiful. The longitudinal section of the sealing body is set to an arch, which can not only leave space for the installation of the door sealing component, but also better maintain the shape when squeezed, which is beneficial to the lower sealing of the first lip. The mounting portion is arranged to be accommodated between the sealing body and the door panel, which can better utilize the space under the door and make the structure more compact. The free end of the basic sealing part is connected to the mounting portion, so that the position of the free end can be fixed, and the shape and position of the sealing body can be better maintained when the first lip is squeezed. The supporting frame can enhance the overall strength of the door sealing component, so that the sealing part is not prone to sagging and deformation after long-term extrusion and aging; the clamping portion passes through the mounting hole and is clamped with the door sheet metal, which is relatively simple to install and has a good fixing effect.

[0022] Furthermore, the mounting holes are divided into positioning holes and long through holes. The positioning holes can accurately locate the mounting position of the support frame, while the long through holes can absorb the tolerance of the length of the door sealing component, making the door sealing component more flat and firm to install and have a better appearance. Setting a weak part in the basic sealing part can provide a more sufficient contact area with the folding edge of the support frame, thereby improving the connection strength between the two. Setting an extension at the free end of the basic sealing part can prevent the top of the support frame from hard contact with the door sheet metal, and the sealing base can form a seal with the door sheet metal.

[0023] Another object of the utility model is to provide a vehicle door, comprising a vehicle door sheet metal and a vehicle door outer panel covering the outside of the vehicle door sheet metal, wherein the vehicle door sealing component mentioned above is mounted on the vehicle door sheet metal.

[0024] The vehicle door described in the present invention has the same beneficial effects as the vehicle door sealing component described above relative to the prior art, which will not be described in detail herein. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] Embodiment 1

[0044] The present embodiment relates to a vehicle door sealing component, which optimizes the sealing structure of the lower sealing part of the Z-axis split door to improve the use quality of the vehicle.

[0045] In terms of overall structure, the door sealing component of this embodiment is installed at the part where the door sheet metal 1 and the outer rocker plate 2 face each other, and the door sealing component includes a sealing portion 3, and the sealing portion 3 includes a sealing body 301 and a first lip 302. The sealing body 301 is retained on the door sheet metal 1 along the length direction of the vehicle body, and the first lip 302 is connected to the sealing body 301 and extends toward the outer rocker plate 2. When the door is closed, the first lip 302 is attached below the curved corner 201 of the outer rocker plate 2.

[0046] Generally speaking, when a vehicle with a Z-direction split door is in a closed state, a channel is formed between the door sheet metal 1 and the outer rocker plate 2. During the driving process of the vehicle, muddy water and dust may enter the curved corner 201 of the outer rocker through this channel. The door sealing component of the utility model is arranged as above, so that the sealing part 3 is connected to the door sheet metal 1, and the first lip edge 302 contacts and seals with the outer rocker plate 2, and the sealing position is lower than the curved corner 201 of the outer rocker plate 2. In specific implementation, the sealing part 3 of this embodiment can block the gap between the door and the outer rocker plate 2, so that the external muddy water and dust are not easy to enter the curved corner 201 of the outer rocker plate 2, which is conducive to keeping the curved corner 201 of the outer rocker plate 2 clean, and does not pollute the legs of the occupants when getting on and off the vehicle, thereby improving the use quality of the vehicle.

[0047] Based on the above overall introduction, specifically, refer to Figure 1-Figure 6 The door sealing member in this embodiment is installed on the door sheet metal 1 at the bottom of the door. Compared with the conventional arrangement of the sealing member on the outer door sill plate 2, it prevents the passengers from stepping on the door sealing member when getting on and off the vehicle, making the door sealing member less likely to be damaged and prolonging its service life. The sealing portion 3 is as long as the bottom of the door, and its two ends are flush with the two ends of the bottom of the door, respectively, which can ensure the sealing integrity of the lower sealing portion of the door.

[0048] In order to protect the first lip 302, refer to Figure 4-Figure 6 When the door is closed, the first lip 302 is covered by the door outer panel 5. During use, the first lip 302 is protected by the door outer panel 5, so it is not easily hit from the side, so that the first lip 302 is not easily damaged, thereby increasing the service life of the sealing portion 3.

[0049] Regarding the structure of the sealing body 301, the longitudinal section of the sealing body 301 of the present embodiment is constructed as an arch that is buckled on the door sheet metal 1. Setting the longitudinal section of the sealing body 301 to an arch can leave a space between the sealing body 301 and the door sheet metal 1, and other structures can be accommodated in the space. The sealing body 301 can also cover some undesirable features on the door sheet metal 1, such as drainage holes, welding points, scraping glue and other parts that affect the appearance, thereby improving the overall appearance quality of the door. It is worth noting that the sealing body 301 can also be set to a straight plate shape or a bent plate shape, but the use effect and service life are not as good as the sealing body 301 with an arched longitudinal section in the present embodiment.

[0050] In this embodiment, the sealing part 3 is made of elastic material, preferably TPV (Thermoplastic Vulcanizate) material, with a hardness of 60HA-70HA, and has the characteristics of high strength, high elasticity, non-curing, and injection molding. It is also environmentally friendly, non-toxic and safe, and is an ideal material for car door seals. Of course, the sealing part 3 can also be made of other elastic sealing materials.

[0051] As for the other parts of the door sealing component, refer to Figure 5 and Figure 6 , specifically also includes a mounting portion 4, which is accommodated in the cavity between the sealing body 301 and the door sheet metal 1 to form a fixed connection between the sealing body 301 and the door sheet metal 1. After the door sealing component is installed, the mounting portion 4 is located between the sealing body 301 and the door sheet metal 1, and is accommodated below the door sheet metal 1, which can effectively utilize the space below the door sheet metal 1 to make the overall structure more compact. After the door is opened, the mounting portion 4 will not be exposed due to the shielding of the sealing portion 3, and the appearance quality of the bottom of the door is better. The sealing portion 3 is formed on the mounting portion 4 by a secondary injection molding process, and can be designed in accordance with the door sheet metal 1 and the outer threshold plate 2 without being restricted by the structure.

[0052] As a further refinement of the structure of the sealing body 301, the sealing body 301 includes a basic sealing portion 3011 and a second lip 3012 connected along the height direction of the vehicle body. The mounting portion 4 is mounted at the free end of the basic sealing portion 3011, that is, the end of the basic sealing portion 3011 close to the door sheet metal 1. An angle is set between the second lip 3012 and the basic sealing portion 3011, and the second lip 3012 is bent and extends toward the direction of the door sheet metal 1. The bottom end of the door outer panel 5 is bent inward to form a rim 501, and the rim 501 wraps around the bottom end of the door sheet metal 1. The inner side of the connection between the rim 501 and the door sheet metal 1 is adhered with a sheet metal rim glue 6, and the second lip 3012 abuts against the surface of the sheet metal rim glue 6, and is pressed against the sheet metal rim glue 6 to form a lower seal of the space between the sealing body 301 and the door sheet metal 1.

[0053] It should be noted that when the vehicle door is closed, the second lip 3012 and the first lip 302 are subjected to extrusion force from both sides, and the first lip 302 and the second lip 3012 are close to each other to produce a supporting effect on each other, which is beneficial to the shape maintenance and sealing effect of the first lip 302 and the second lip 3012.

[0054] In the overall structure of the sealing part 3, specifically, the basic sealing part 3011 and the first lip 302 together form an "S"-shaped longitudinal section. When the door is closed, the first lip 302 bends toward the outer rocker plate 2 and is pressed against the outer rocker plate 2. The first lip 302 is preset with an interference amount after being pressed against the outer rocker plate 2. When the first lip 302 is pressed against the outer rocker plate 2, the stress is transmitted along the main extension direction of the first lip 302, and elastic deformation occurs together with the sealing body 301 to cope with the pressing. The sealing body 301 and the first lip 302 can both maintain their shapes well, which is beneficial to the sealing performance of the first lip 302. In this embodiment, when the door is closed, the interference amount between the first lip 302 and the outer rocker plate 2 is 3mm-3.5mm, which can ensure the pressure between the first lip 302 and the outer rocker plate 2 to ensure the sealing performance, and prevent the overall deformation of the sealing part 3 from being excessive. The second lip 3012 is preset with an interference amount with the sheet metal edge glue 6, specifically 0.5mm-1mm.

[0055] For the structure of the mounting portion 4, refer to Figure 1 and Figure 6 Specifically, it includes a support frame 401 and a plurality of clamping parts 402. The support frame 401 is extended along the length direction of the vehicle body and fixedly connected to the base sealing part 3011 near the free end of the base sealing part 3011. A plurality of mounting holes adapted to the clamping parts 402 are provided on the support frame 401, and the mounting holes are arranged at intervals along the extension direction of the support frame 401. The clamping parts 402 pass through the mounting holes from the inner side of the support frame 401 to be clamped on the door sheet metal 1. The support frame 401 can support the sealing part 3, improve the overall strength of the door sealing component, make the sealing part 3 less likely to sag and deform after long-term extrusion and aging, and improve the durability of the door sealing component. The door sheet metal 1 is provided with a hole for the clamping part 402 to be clamped, and the clamping part 402 passes through the mounting holes to be clamped with the door sheet metal 1, which is easy to install, easy to operate, and has a good fixing effect.

[0056] Specifically, the support frame 401 and the clamping part 402 can be made of PP+EPDM-TD20 material, which has the characteristics of anti-scratch and balanced rigidity and toughness, so that the connection strength between the support frame 401 and the clamping part 402 is high and not easy to break. The support frame 401 and the clamping part 402 can also be made of other similar materials as long as they can meet the strength and toughness requirements.

[0057] It should be noted that the support frame 401 and the clamping part 402 can also be integrally formed, eliminating the need for the installation hole, and can be directly clamped on the door sheet metal 1 during assembly. However, this method requires high manufacturing accuracy. If the manufacturing accuracy is not up to standard, the mounting part 4 will not match the door sheet metal 1. At the same time, if a break occurs between the clamping part 402 and the support frame 401 during assembly, the entire mounting part 4 will be scrapped. Alternatively, the clamping part 402 can also be set as a bolt, and the threaded end of the bolt is threadedly connected to the door sheet metal 1 after passing through the installation hole, so as to fix the position of the support frame 401. However, this method requires a large number of bolts to be screwed during installation, and the installation efficiency is low.

[0058] The bottom of the door is relatively long, and the position of the door sheet metal 1 corresponding to the mounting hole will have a hole opening tolerance. In order to reduce the influence of the tolerance on the installation of the support frame 401, refer to Figure 1-Figure 3 The plurality of mounting holes include long through holes 4012 distributed in the main area of ​​the support frame 401, and positioning holes 4011 arranged near the edge of the support frame 401. The positioning holes 4011 are round holes located at the rear end of the support frame 401 in the vehicle direction, and are used to perform the first point positioning of the support frame 401. A plurality of long through holes 4012 are arranged at intervals along the length direction of the support frame 401, and after the clamping portion 402 is installed, they can adapt to absorb the lateral tolerance, so that the support frame 401 is more closely connected to the door sheet metal 1.

[0059] Specifically, refer to Figure 1 and Figure 6 , the clamping part 402 is a buckle, which has two elastic claws and a pressing cap 4021. After the buckle is inserted into the long through hole 4012, the two claws will stretch in the length direction of the long through hole 4012 due to the elastic force, so that the buckle is not easy to rotate during installation. After the buckle is installed, the pressing cap 4021 will press the support frame 401 on the door sheet metal 1. The spacing between adjacent buckles is 80mm-100mm, and they are evenly arranged. The distance between the two buckles at the two ends of the corresponding sealing part 3 and the end of the adjacent sealing part 3 is less than 30mm. After the door sealing component of this embodiment is installed, all buckles are hidden inside the sealing part 3, making the lower part of the door more beautiful as a whole, and the lowest end of the support frame 401 is 1mm-2mm lower than the lowest end of the pressing cap 4021, which can not only ensure the connection strength between the buckle and the support frame 401, but also reduce the material consumption of the support frame 401 and reduce the weight of the whole vehicle.

[0060] In order to make the support frame 401 fit more closely with the door sheet metal 1, a boss 4013 is provided at the opening of the mounting hole on the side of the support frame 401 facing the door sheet metal 1. The boss 4013 is in direct contact with the door sheet metal 1, which can reduce the contact points between the support frame 401 and the door sheet metal 1, making it easier for the buckle to snap into place and making the installation more secure. Specifically, the height of the boss 4013 can be 0.5 mm.

[0061] In order to improve the connection strength between the basic sealing part 3011 and the support frame 401, a weak portion 3013 is formed on the inner surface of the free end of the basic sealing part 3011. A folded edge is formed on the upper edge of the support frame 401, and the folded edge is abutted and fixedly connected to the weak portion 3013. In this embodiment, the sealing part 3 is connected to the support frame 401 by secondary injection molding. The folded edge can make the support frame 401 have a larger contact area with the weak portion 3013, and the folded edge is tightly and firmly connected to the weak portion 3013.

[0062] The support frame 401 has a certain rigidity. In actual use, its top may make abnormal noise when in contact with the door sheet metal 1. Therefore, the free end of the basic sealing part 3011 has an extension that goes over the support frame 401 and abuts against the door sheet metal 1. The extension part is located at the end of the weak part 3013, and there is a preset interference of 0.5 mm between the extension part and the door sheet metal 1, which can play a certain elastic supporting role on the top of the support frame 401 and form a seal above the support frame 401.

[0063] The door sealing structure of this embodiment is in an assembled state before installation, and the sealing part 3 and the mounting part 4 have been connected. When the door sealing structure is installed, the rear end clamping part 402 is used as the starting installation position, and is clamped into the hole corresponding to the door sheet metal 1, and then the remaining clamping parts 402 are installed in sequence. When installing the clamping part 402, you can put your hand into the inner side of the sealing part 3 and blindly press the clamping part 402.

[0066] As configured above, the vehicle door of this embodiment has a sealing portion 3, which can block the gap between the vehicle door and the outer rocker plate 2, so that external mud, water and dust are not easy to enter the bending corner 201 of the outer rocker plate 2, which is beneficial to keeping the bending corner 201 of the outer rocker plate 2 clean, and does not contaminate the legs of the passengers when the passengers get on and off the vehicle, thereby improving the use quality of the vehicle.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
