Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and in particular to a door assembly and a vehicle. Background Technology

[0002] With the continuous development of the automotive industry, people have increasingly higher demands for the comfort, appearance, functionality, and aesthetics of cars. When designing vehicles, manufacturers strive to make the B-pillars of the doors as narrow as possible, which can improve the openness of the interior space and enhance the vehicle's appearance.

[0003] In related technologies, the B-pillar of a car door often includes an inner panel and a reinforcing plate. The reinforcing plate is equipped with a mounting structure for connecting with the sealing strip, such as a snap-fit ​​structure and mounting holes. On the one hand, the reinforcing plate is integrally molded, and setting the mounting structure on the reinforcing plate will increase the manufacturing process difficulty of the reinforcing plate. On the other hand, the connection position between the reinforcing plate and the inner panel needs to avoid the mounting structure on the reinforcing plate, which results in a larger width of the entire reinforcing plate, which is not conducive to narrowing the B-pillar of the car door. Utility Model Content

[0010] The door assembly according to the embodiment of this utility model has at least the following beneficial effects:

[0011] This application avoids direct connection between the seal and the sheet metal part by using a mounting component. The mounting component is made of metal and can be fixed to the sheet metal part through welding, threaded connections, or other methods, eliminating the need for complex mounting structures on the sheet metal part. This simplifies the manufacturing process of the sheet metal part and reduces the defect rate. Secondly, the connection structure between the mounting component and the sheet metal part is smaller in size, reducing the width requirements of the sheet metal part and effectively reducing its overall width. This further facilitates the narrowing design of the B-pillar of the door, improving the interior space and the vehicle's aesthetics.

[0012] According to some embodiments of the present invention, the sheet metal part includes an inner plate and a reinforcing plate that are connected to each other. The reinforcing plate includes a first connecting part that is connected to the mounting part and a second connecting part that is connected to the inner plate.

[0014] According to some embodiments of the present invention, the first snap-fit ​​portion includes a first protrusion and a first buckle arranged sequentially along a first direction, and the second snap-fit ​​portion includes a first groove and a second buckle. The first groove has a first groove wall and a second groove wall opposite to each other along the first direction, and the second buckle is connected to the second groove wall.

[0015] The first protrusion is inserted into the first groove and abuts against the first groove wall, and the first buckle and the second buckle are engaged with each other.

[0018] And / or, the first snap-fit ​​portion includes a plurality of first protrusions, each of the first protrusions being spaced apart along a second direction intersecting the first direction, and the mounting member further includes a third connecting portion connected to the sheet metal part, the third connecting portion being located between two adjacent first protrusions.

[0019] According to some embodiments of the present invention, the door assembly further includes a trim panel and threaded fasteners, wherein the trim panel and the sheet metal part are connected by the threaded fasteners.

[0020] According to some embodiments of the present invention, the decorative panel includes a main body and a support portion protruding from the main body, and the sheet metal part is connected to the support portion of the decorative panel so that a first gap for accommodating the seal is defined between the sheet metal part and the main body.

[0021] According to some embodiments of the present invention, a portion of the sealing element is located in the first gap, with one side of the sealing element abutting against the mounting element along a third direction and the other side abutting against the decorative panel, thereby restricting the displacement of the sealing element along the third direction.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] With the continuous development of the automotive industry, people have increasingly higher demands for the comfort, appearance, functionality, and aesthetics of cars. When designing vehicles, manufacturers strive to make the B-pillars of the doors as narrow as possible, which can improve the openness of the interior space and enhance the vehicle's appearance.

[0042] In related technologies, the B-pillar of a car door typically includes an inner panel, a reinforcing plate, and a sealing strip. The inner panel and the reinforcing plate are welded together. Since the sealing strip is made of a flexible material, it cannot be welded to the reinforcing plate. Therefore, the reinforcing plate needs to be equipped with an installation structure for connecting to the sealing strip, such as a snap-fit ​​structure or mounting holes. On the one hand, since the reinforcing plate is integrally molded, setting an installation structure on the reinforcing plate will increase the manufacturing process difficulty of the reinforcing plate, resulting in a higher defect rate. On the other hand, the welding position between the reinforcing plate and the inner panel needs to avoid the installation structure on the reinforcing plate, which results in a larger width of the entire reinforcing plate, which is not conducive to narrowing the B-pillar of the car door.

[0043] To solve the above problems, such as Figures 1 to 4 As shown, this application proposes a novel door assembly, which includes a sheet metal part 100, a mounting part 200, and a seal 300. The sheet metal part 100 is the main frame of the door, and the mounting part 200, the seal 300, and the door glass 600 are all directly or indirectly connected to the sheet metal part 100. The seal 300 is often made of flexible materials such as rubber, which can fit tightly against the door glass 600 to achieve sound insulation and waterproofing functions.

[0044] It should be noted that in this application, the seal 300 is not directly mounted on the sheet metal part 100, but is indirectly fixed through the mounting part 200. For example... Figure 2 As shown, the mounting component 200 is connected to the side of the sheet metal part 100 facing outwards from the vehicle, and the seal 300 is connected to the mounting component 200. More specifically, as... Figure 2 and Figure 3As shown, the seal 300 and the mounting component 200 are connected by a snap-fit ​​mechanism. The mounting component 200 includes a first snap-fit ​​portion 210, and the seal 300 includes a second snap-fit ​​portion 310. The first snap-fit ​​portion 210 of the mounting component 200 and the second snap-fit ​​portion 310 of the seal 300 are engaged to allow the seal 300 to be detachably connected to the mounting component 200. It is understood that this snap-fit ​​mechanism enables rapid installation and replacement of the seal 300, thus improving assembly efficiency.

[0045] The adapter 200 prevents the seal 300 from directly connecting to the sheet metal part 100. For example... Figure 2 As shown, the mounting component 200 is located between the sealing component 300 and the sheet metal component 100, separating the sealing component 300 from the sheet metal component 100. The mounting component 200 is made of metal and can be fixed to the sheet metal component 100 through welding, threaded connections, or other connection methods. Alternatively, it can be made of hard materials such as hard plastic and can be fixed to the sheet metal component 100 through threaded connections, eliminating the need for complex mounting structures on the sheet metal component 100, thus simplifying the manufacturing process of the sheet metal component 100 and reducing the defect rate. Secondly, the connection structure between the mounting component 200 and the sheet metal component 100 has a smaller size. For example, when the mounting component 200 and the sheet metal component 100 are connected by welding, the weld area is small and the position is flexible, reducing the width requirements of the sheet metal component 100 and effectively reducing the overall width of the sheet metal component 100. This further promotes the narrowing design of the B-pillar of the door, improving the interior space and the vehicle's aesthetics.

[0046] It is understandable that the number of mounting parts 200 can be one, arranged along the length of the seal 300 on the second side of the sheet metal part 100, with the mounting part 200 continuously connected to the seal 300, thus achieving a good fixing effect. Alternatively, there can be multiple mounting parts, distributed at intervals along the length of the seal 300, to connect intermittently with the seal 300, which is beneficial for achieving vehicle weight reduction.

[0047] In some embodiments, the sheet metal part 100 includes an inner plate 110 and a reinforcing plate 120, and the inner plate 110 and the reinforcing plate 120 are connected. For example... Figure 2 As shown, the reinforcing plate 120 includes a first side and a second side disposed opposite to each other along its thickness direction. The first side faces the interior space of the vehicle and is fixedly connected to the inner plate 110. The connection method is not limited to threaded connection, riveting or welding. The second side faces the outside of the vehicle and is used to install the seal 300.

[0048] The reinforcing plate 120 includes a first connecting portion 121 and a second connecting portion 122. The first connecting portion 121 is used to connect with the mounting component 200, and the second connecting portion 122 is used to connect with the inner plate 110. The connection method between the reinforcing plate 120 and the mounting component 200 can be threaded, riveted, or welded, etc. The connection method between the reinforcing plate 120 and the inner plate 110 can also be threaded, riveted, or welded, etc. The connection method between the reinforcing plate 120 and the mounting component 200 can be the same as or different from the connection method between the reinforcing plate 120 and the inner plate 110. Taking welding the reinforcing plate 120 to the mounting component 200 and welding the reinforcing plate 120 to the inner plate 110 as an example (e.g.) Figure 2 As shown, Figure 2 (The black dots in the image represent weld points.) The first connecting part 121 is the weld point for welding to the mounting part 200, and the second connecting part 122 is the weld point for welding to the inner plate 110. To avoid structural strength problems caused by overlapping weld points during welding, the weld points should be staggered. Therefore, along the first direction, the first connecting part 121 and the second connecting part 122 are spaced apart. It is understood that if the first connecting part 121 and the second connecting part 122 are riveted, threaded, or other installation structures, a certain distance must also be maintained.

[0049] It should be noted that, as Figure 1 and Figure 2 As shown, for ease of description, this application defines a first direction, a second direction, and a third direction, wherein any two are intersecting, and preferably, any two are perpendicular. The first direction is the width direction of the mounting member 200, the second direction is the length direction of the mounting member 200, and the third direction is the thickness direction of the mounting member 200. Wherein, in... Figure 1 In the illustrated embodiment, the mounting member 200 is inclined relative to the vertical direction, thus, the first direction is inclined relative to the horizontal plane, and the second direction is inclined relative to the vertical plane. If the mounting member 200 extends along the vertical plane, then the first direction is horizontal, that is, along the front-rear direction of the vehicle body, the second direction is vertical, that is, along the height direction of the vehicle body, and the third direction is along the inner-outer direction of the vehicle body.

[0050] Furthermore, along the first direction, both ends of the reinforcing plate 120 are connected to the inner plate 110, and the middle portion of the reinforcing plate 120 and the inner plate 110 are spaced apart. For ease of description, the reinforcing plate 120 is defined as including a central region 123 and two end regions 124, with the end regions 124 located on both sides of the central region 123 along the first direction. The end regions 124 are used for connection with the inner plate 110, thereby, a second connecting portion 122 is provided in the end regions 124. The central region 123 is spaced apart from the inner plate 110, as shown below. Figure 3As shown, the middle portion of the inner panel 110 is recessed towards the interior space, thereby forming a cavity 130 with the middle region 123 of the reinforcing panel 120. The first connecting portion 121 is disposed in the middle region 123, corresponding to the cavity 130, thereby avoiding the overlapping end regions 124 of the reinforcing panel 120 and the inner panel 110.

[0051] In some embodiments, such as Figure 3 As shown, the first engaging portion 210 includes a first protrusion 211 and a first latch 212, which are sequentially arranged along a first direction. The second engaging portion 310 includes a first groove 311 and a second latch 312. The first groove 311 has a first groove wall 3111 and a second groove wall 3112 arranged opposite to each other along the first direction, and the second latch 312 is connected to the second groove wall 3112. Figure 2 As shown, when the seal 300 is assembled with the mounting part 200, the first snap 212 and the second snap 312 engage with each other, and the first protrusion 211 is inserted into the first groove 311 and abuts against the first groove wall 3111, thereby tightening the seal 300 to prevent the first snap 212 and the second snap 312 from loosening.

[0052] Understandably, the width of the first protrusion 211 can be approximately equal to the width of the first groove 311. The first latch 212 is located on one side of the first protrusion 211 (not shown in the figure). When the first protrusion 211 is inserted into the first groove 311, the first latch 212 on one side of the first protrusion 211 and the second latch 312 are tightly engaged. The sidewall of the other side of the first protrusion 211 is tightly fitted to the wall of the first groove 3111, ensuring that the seal 300 is not easily displaced during installation. Alternatively, as... Figure 3 As shown, the width of the first protrusion 211 is much smaller than the width of the first groove 311. The first latch 212 and the first latch 212 are connected to the main body of the mounting component 200 as two independent parts, and the first protrusion 211 and the first latch 212 are spaced apart. Through this design, the width of the first protrusion 211 is reduced, thereby reducing the weight of the mounting component 200.

[0053] Additionally, the mounting component 200 includes a third connecting portion 220 that connects to the reinforcing plate 120 in the sheet metal component 100. The third connecting portion 220 can be a weld point formed by welding, a hole required for screwing or riveting, or a connecting structure required for other connection methods. It should be noted that the third connecting portion 220 is used to connect with the first connecting portion 121. Taking welding as an example, the welding process can preferably be MIG welding (metal inert gas welding), or other welding processes. After the mounting component 200 is welded and fixed to the reinforcing plate 120, the first connecting portion 121 is formed on the reinforcing plate 120, and the third connecting portion 220 is formed on the mounting component 200.

[0054] In some embodiments, the third connecting portion 220 is disposed between the first protrusion 211 and the first latch 212. Taking the third connecting portion 220 as a welding point as an example, since the portion of the mounting member 200 between the first protrusion 211 and the first latch 212 is thinner, a penetrating molten pool can be formed more easily during welding, reducing the risk of incomplete soldering. Similarly, if the mounting member 200 and the reinforcing plate 120 are screwed or riveted, since the mounting member 200 and the reinforcing plate 120 are thinner at this location, the screws or rivets can penetrate more firmly, reducing the possibility of loosening or falling off the connection.

[0055] In other embodiments, the third connecting portion 220 may also be disposed between two adjacent first latches 212, or between two adjacent first protrusions 211. Specifically, as shown below... Figure 1 As shown, the mounting component 200 includes a plurality of first latches 212, each of which is spaced apart along the second direction. The third connecting portion 220 is located between two adjacent first latches 212, thereby ensuring that the welding position does not affect the setting of the first latches 212, further reducing the risk of the welding area coinciding with the setting position of the first latches 212. Similarly, the first protrusions 211 can also be made into an intermittent structure (not shown in the figure). For example, the mounting component 200 includes a plurality of first protrusions 211, each of which is spaced apart along the second direction. The third connecting portion 220 is located between two adjacent first protrusions 211, ensuring that the welding area does not coincide with the setting position of the first protrusions 211.

[0056] In such Figure 1 In the illustrated embodiment, the mounting member 200 includes a plurality of first snaps 212 and a continuous first protrusion 211. The first protrusion 211 extends along a second direction, and the plurality of first snaps 212 are spaced apart along the length direction of the mounting member 200. When the sealing member 300 is installed onto the mounting member 200, various installation methods can be employed. For example, one end of the sealing member 300 can be snapped into the end of the mounting member 200, and then the sealing member 300 can be moved along the length direction of the mounting member 200 until the entire sealing member 300 is installed onto the mounting member 200. Alternatively, since the sealing member 300 has a certain elastic deformation capability, the first protrusion 211 can be inserted into the first groove 311 firstly, and then the elasticity of the sealing member 300 can be used to pry open the second snaps 312, so that each second snap 312 is sequentially embedded into its corresponding first snap 212.

[0057] In the prior art, the door assembly also includes a trim panel, the inner surface of which can be provided with a buckle to engage with a reinforcing plate to fix the trim panel and the door sheet metal parts. However, setting a buckle structure on the reinforcing plate will place higher requirements on the width of the reinforcing plate.

[0058] In some embodiments of this application, the door assembly further includes a threaded fastener 500, and the trim panel 400 and the reinforcing plate 120 in the sheet metal part 100 are connected by the threaded fastener 500. It is understood that the threaded fastener 500 is connected through pre-drilled holes in the reinforcing plate 120, simplifying the connection structure on the reinforcing plate 120, thereby further reducing the manufacturing difficulty of the reinforcing plate 120 and further reducing the width of the reinforcing plate 120.

[0059] Furthermore, such as Figure 2 and Figure 4 As shown, the trim panel 400 includes a main body 430 and a support portion 410 protruding from the main body 430. The support portion 410 includes an extension 411 protruding from the inner surface of the main body 430 and an abutment portion 412 located at the end of the extension 411 for contacting the reinforcing plate 120. The reinforcing plate 120 abuts against the abutment portion 412 of the support portion 410. This arrangement can reduce the contact area between the reinforcing plate 120 and the trim panel 400 to avoid an increase in the probability of abnormal noise caused by large-area contact. On the other hand, a first gap 413 for accommodating the sealing member 300 can be defined between the reinforcing plate 120 and the main body 430 to clamp the sealing member 300 between the reinforcing plate 120 and the main body 430 and limit the displacement of the sealing member 300 in a third direction.

[0060] Furthermore, such as Figure 2 and Figure 3 As shown, the seal 300 includes a first abutting portion 320, a bent portion 330, a second snap-fit ​​portion 310, and a second abutting portion 340 connected in sequence. The first abutting portion 320 abuts against the outer side of the door glass 600. The bent portion 330 extends into the first gap 413, and its two sides along the third direction abut against the main body 430 of the trim panel 400 and the reinforcing plate 120, respectively, to limit the displacement of the seal 300 along the third direction and prevent the seal 300 from loosening. In addition, the seal 300 also prevents dust and moisture from entering the door interior through the first gap 413, ensuring the cleanliness and dryness of the door interior. More specifically, as... Figure 2 and Figure 3 As shown, the trim panel 400 may also be provided with an abutment protrusion 420, and the portion of the seal 300 that abuts against the trim panel 400 may be provided with an abutment groove 350. The abutment protrusion 420 can cooperate with the abutment groove 350 to improve the sealing performance of the connection between the seal 300 and the trim panel 400 and reduce the possibility of moisture and dust intrusion. The second abutment portion 340 abuts against the door glass 600 and the mounting member 200 on both sides along the third direction, thereby restricting the movement of the other end of the seal 300.

[0061] The second aspect of this application also proposes a vehicle, which includes a body and a door assembly as mentioned in any of the foregoing embodiments. It should be noted that the vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle. Since the vehicle in this aspect of the embodiment includes the door assembly of the above embodiments, it has the beneficial effects of the above embodiments, which will not be repeated here.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
