[0039] It should be noted that for ease of description, in the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, in different embodiments, the detailed description of the same components is omitted.

[0040] In the related art, the water cut decorative strip of the water cut trim assembly product of a vehicle is usually directly snap-connected to the water cut sealing strip and fixed to the body sheet metal by relying on the sealing strip. In this assembly method, after the water cut trim assembly is set on the vehicle, there is likely to be a step difference between the water cut trim of the front door and the water cut trim of the rear door, which affects the user's visual perception; in addition, problems such as loose assembly and inability to be installed often occur in the water cut trim assembly, resulting in the risk of abnormal noise during vehicle driving and even the water cut trim falling off; the loose assembly of the water cut trim assembly is likely to cause problems such as noise, vibration, and harshness (Noise, Vibration, Harshness, abbreviated as NVH).

[0041] Please refer to Figures 1 to 5 , an embodiment of this application provides a door assembly 100, which includes: a door sheet metal 10; a seal 20 sleeved on one end of the door sheet metal 10; a decorative member 30 disposed on one side of the seal 20; and a connection assembly 40 passing through the door sheet metal 10, the seal 20, and the decorative member 30 respectively to connect the door sheet metal 10, the seal 20, and the decorative member 30.

[0042] The door assembly 100 of this application can be applied to vehicles such as automobiles, sedans, trucks, freight cars, and trains.

[0043] The connection assembly 40 passes through the door sheet metal 10, the seal 20, and the decorative member 30 in sequence to connect the door sheet metal 10, the seal 20, and the decorative member 30. It can be understood that the connection assembly 40 penetrates through the door sheet metal 10 and the seal 20 and is partially embedded in the decorative member 30, and the door sheet metal 10, the seal 20, and the decorative member 30 are tightly fixed through the connection assembly 40.

[0044] It should be noted that the seal 20 is disposed at one end of the door sheet metal 10, covers the side surface of the door sheet metal 10, and extends to two opposite surfaces connected to the side surface, so that the seal 20 is sleeved on a part of the door sheet metal 10.

[0045] It should be noted that when the door assembly 100 is applied to a vehicle, the decorative member 30 is disposed close to the outer surface of the vehicle; in other words, the decorative member 30 is part of the appearance surface of the vehicle.

[0046] Optionally, the door sheet metal 10 includes a connected sheet metal part 11 and a body skin 12, and the body skin 12 is disposed on the surface of the sheet metal part 11 to improve the appearance effect of the door sheet metal 10. It can be understood that when the door assembly 100 is installed on a vehicle, the body skin 12 is part of the appearance surface of the vehicle.

[0047] It should be noted that the connecting assembly 40 respectively passes through the sheet metal part 11, the seal 20 and the decorative member 30 to connect the sheet metal part 11, the seal 20 and the decorative member 30.

[0048] The door assembly 100 according to the embodiment of the present application includes a door sheet metal 10, a seal 20, a decorative member 30 and a connecting assembly 40. The connecting assembly 40 sequentially passes through the door sheet metal 10, the seal 20 and the decorative member 30 to connect the door sheet metal 10, the seal 20 and the decorative member 30. The door sheet metal 10, the seal 20 and the decorative member 30 are connected by the connecting assembly 40, so that the connection between the door sheet metal 10, the seal 20 and the decorative member 30 is more stable. When the door assembly 100 is applied to a vehicle, it is less likely to become loose and generate abnormal noises, and the assembly accuracy of the decorative member 30 and the seal 20 can also be improved; in addition, the relative position between the decorative member 30 and the seal 20 can be adjusted by the tightening degree of the connecting assembly 40, so as to adjust the position of the surface of the decorative member 30 facing away from the seal 20. When the door assembly 100 is applied to a vehicle and there are at least two door assemblies 100 on the same side of the vehicle, the tightening degree of the connecting assembly 40 can be adjusted to make the decorative members 30 on at least two door assemblies 100 flush or smoothly transition, so as to solve the step difference problem of the decorative members 30 on at least two door assemblies 100 and the step difference problem between the decorative member 30 and other components on the door assembly 100, and improve the appearance effect of the vehicle. Furthermore, a seal 20 is provided between the decorative member 30 and the door sheet metal 10, which can better avoid gaps between the decorative member 30 and the door sheet metal 10 and has a better sealing effect.

[0049] Please refer to Figure 6 and Figure 7In one embodiment, the connecting component 40 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 is located between the sealing member 20 and the decorative member 30, and the first connecting member 41 is at least partially embedded in the decorative member 30; the second connecting member 42 is sequentially passed through the vehicle door sheet metal 10, the sealing member 20 and the first connecting member 41, and the second connecting member 42 abuts against the side of the vehicle door sheet metal 10 away from the decorative member 30.

[0050] Optionally, the number of the connecting assemblies 40 may be one or more. When the number of the connecting assemblies 40 is multiple, the connecting assemblies 40 are sequentially spaced apart along the extension direction of the decorative member 30. Specifically, the number of the connecting assemblies 40 may be, but is not limited to, 1, 2, 3, 4, 5, etc. The number of the connecting assemblies 40 can be designed based on the length of the decorative member 30 and is not specifically limited in this application.

[0051] "Plurality" means at least two.

[0052] The number and position of the connecting components 40 can be flexibly adjusted and set according to actual needs, including but not limited to being set at the front, middle and rear positions of the door assembly 100; then the corresponding positions of the door sheet metal 10, the seal 20 and the decorative part 30 are drilled, and one connecting component 40 corresponds to one through hole of the door sheet metal 10, the seal 20 and the decorative part 30 to ensure a firm connection without loosening or falling off, which is convenient for installing and adjusting the decorative strips.

[0053] It should be noted that the first connecting member 41 is located between the decorative member 30 and the sealing member 20 . The first connecting member 41 is partially embedded in the surface of the decorative member 30 facing the sealing member 20 .

[0054] It should be noted that the first connecting member 41 is at least partially embedded in the decorative member 30. It can be: the first connecting member 41 is partially embedded in the decorative member 30 and partially protrudes from the surface of the decorative member 30 facing the seal 20; it can also be: the first connecting member 41 is entirely embedded in the surface of the decorative member 30 facing the seal 20, and the surface of the first connecting member 41 facing the seal 20 is flush with the surface of the decorative member 30 facing the seal 20.

[0055] It can be understood that the second connecting member 42 is connected to the first connecting member 41 .

[0056] When installing the vehicle door assembly 100, the first connecting member 41 is first installed on the side of the decorative member 30 facing the seal 20, and the second connecting member 42 is inserted into the vehicle door sheet metal 10, the seal 20 and the first connecting member 41 in sequence from the side of the vehicle door sheet metal 10 away from the seal 20, so as to assemble the vehicle door sheet metal 10, the seal 20 and the decorative member 30 into one.

[0057] In this embodiment, the connecting assembly 40 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 is located between the sealing member 20 and the decorative member 30, and at least a part of the first connecting member 41 is embedded in the decorative member 30. The second connecting member 42 sequentially passes through the vehicle door sheet metal 10, the sealing member 20 and the first connecting member 41, and the second connecting member 42 abuts against the side of the vehicle door sheet metal 10 facing away from the decorative member 30. Through the cooperation of the first connecting member 41 and the second connecting member 42, the assembly of the vehicle door assembly 100 can be better simplified. In addition, the connection between the vehicle door sheet metal 10, the sealing member 20 and the decorative member 30 can be made more stable, and when the vehicle door assembly 100 is applied to a vehicle, it is less likely to become loose and thus generate abnormal noises. Furthermore, by adjusting the depth of the second connecting member 42 passing through the first connecting member 41, the pressing degree between the decorative member 30 and the sealing member 20 can be adjusted, thereby adjusting the position of the side of the decorative member 30 facing away from the sealing member 20. When the vehicle door assembly 100 is applied to a vehicle and there are at least two vehicle door assemblies 100 on the same side of the vehicle, the locking degree of the connecting assembly 40 can be adjusted to make the decorative members 30 on at least two vehicle door assemblies 100 flush or smoothly transition, so as to solve the step difference problem of the decorative members 30 on at least two vehicle door assemblies 100 and improve the appearance effect of the vehicle.

[0058] Please refer to Figure 8 In a specific embodiment, the first connecting member 41 includes a first abutting portion 411, a first passing portion 412 and a clamping portion 413. The first passing portion 412 protrudes from one side of the first abutting portion 411. The clamping portion 413 is disposed on the outer periphery of the first passing portion 412 and is spaced apart from the first abutting portion 411. The decorative member 30 encloses a receiving cavity 31 and the decorative member 30 has a first through hole 32 communicating with the receiving cavity 31. The first passing portion 412 passes through the first through hole 32, the clamping portion 413 abuts against the inner side wall of the receiving cavity 31, and the first abutting portion 411 abuts against the outer side wall of the decorative member 30.

[0059] Optionally, in a direction perpendicular to the arrangement direction of the first abutting portion 411 and the first passing portion 412, the radial dimension of the first abutting portion 411 is greater than the radial dimension of the first passing portion 412.

[0060] It should be noted that the first abutting portion 411, the first passing portion 412 and the clamping portion 413 enclose a receiving groove 414, and the receiving groove 414 is disposed around the outer periphery of the first passing portion 412. When the first connecting member 41 is embedded in the decorative member 30, the receiving groove 414 is used to receive a part of the decorative member 30, so that the first connecting member 41 and the decorative member 30 are more tightly clamped together.

[0061] It should be noted that the radial dimension of the first abutting portion 411 is greater than the dimension of the first through hole 32. Along the arrangement direction of the first penetrating portion 412 and the clamping portion 413, the total length of the first penetrating portion 412 and the clamping portion 413 is greater than the dimension of the first through hole 32, so that when the clamping portion 413 penetrates into the first through hole 32 and is located in the accommodating cavity 31, it can stably abut against the inner side wall of the decorative member 30.

[0062] Optionally, the radial dimension of the first penetrating portion 412 is smaller than the dimension of the first through hole 32.

[0063] It can be understood that the clamping portion 413 is located in the accommodating cavity 31, the first abutting portion 411 is located on the side of the decorative member 30 facing the sealing member 20, and the first penetrating portion 412 penetrates through the first through hole 32 and is partially located in the accommodating cavity 31.

[0064] Optionally, the number of the clamping portions 413 can be one or more. When the number of the clamping portions 413 is multiple, the multiple clamping portions 413 are arranged at intervals around the outer periphery of the first penetrating portion 412. By arranging multiple clamping portions 413, when the first connecting member 41 is embedded in the decorative member 30, the connection between the first connecting member 41 and the decorative member 30 can be more stable and less likely to fall off.

[0065] Optionally, the number of the clamping portions 413 is one, and the clamping portion 413 extends around the outer periphery of the first penetrating portion 412. It can be understood that the clamping portion 413 is an annular structure.

[0066] In this embodiment, the first connecting member 41 includes a first abutting portion 411, a first penetrating portion 412, and a clamping portion 413. Through the cooperation of the first abutting portion 411, the first penetrating portion 412, and the clamping portion 413, when the first connecting member 41 is installed on the decorative member 30, it can be more stably clamped to the decorative member 30, better avoiding the separation between the first connecting member 41 and the decorative member 30. Thus, during the driving of the vehicle, the decorative member 30 can be better prevented from shaking, and the risk of the decorative member 30 falling off can be better avoided.

[0067] Please refer to Figure 7 and Figure 8In some embodiments, the first connecting member 41 has a second through hole 415, which sequentially passes through the first supporting portion 411 and the first penetrating portion 412, and the first connecting member 41 has an internal thread; the second connecting member 42 includes a second supporting portion 421 and a second penetrating portion 422 connected to each other, and the second penetrating portion 422 is protruded on one side of the second supporting portion 421, and the second penetrating portion 422 has an external thread. The second penetrating portion 422 is sequentially passed through the vehicle door sheet metal 10, the sealing member 20 and the second through hole 415, and the second supporting portion 421 presses against the side of the vehicle door sheet metal 10 away from the decorative member 30.

[0068] It should be noted that the first connecting member 41 has an internal thread, the second connecting member 42 has an external thread, and the first connecting member 41 and the second connecting member 42 are connected via threads.

[0069] Along the extension direction of the second penetration portion 422, the length of the second penetration portion 422 is greater than the sum of the length of the second through hole 415, the thickness of the elastic member 43 and the thickness of the vehicle door sheet metal 10, so that when the second penetration portion 422 penetrates the second through hole 415 and is located in the first penetration portion 412 and the first penetration portion 412 is partially located in the accommodating cavity 31, it can be firmly supported against the inner wall of the vehicle door sheet metal 10.

[0070] In this embodiment, when the door assembly 100 is installed, the first connecting member 41 is first installed on the side of the decorative member 30 facing the seal 20, and the second penetration portion 422 of the second connecting member 42 is passed through the door sheet metal 10, the seal 20 and the first connecting member 41 in sequence from the side of the door sheet metal 10 away from the seal 20. Since the first connecting member 41 is threadedly connected to the second connecting member 42, the penetration depth of the second penetration portion 422 can be adjusted by adjusting the tightening degree of the second connecting member 42, thereby adjusting the gap between the decorative member 30 and the seal 20. The degree of compression is adjusted so that the decorative part 30 compresses the seal 20, thereby adjusting the relative position of the decorative part 30 away from the surface of the seal 20; when the door assembly 100 is applied to a vehicle and there are at least two doors on the same side of the vehicle, the second connecting member 42 can be adjusted to adjust the degree of compression between the decorative part 30 and the seal 20, so that the surfaces of the decorative parts 30 of at least two door assemblies 100 away from the seal 20 are flush, so as to avoid the step difference of the decorative parts 30 of at least two door assemblies 100, which affects the appearance of the vehicle.

[0071] See also Figure 8 In some embodiments, in the direction from the decorative member 30 to the sealing member 20 , the width of the clamping portion 413 along the arrangement direction of the clamping portion 413 and the first penetration portion 412 gradually increases.

[0072] It can be understood that the size of the side of the clamping portion 413 facing away from the first abutting portion 411 is smaller than the size of the side of the clamping portion 413 close to the first abutting portion 411 .

[0073] It can be understood that the surface of the engaging portion 413 facing away from the first penetrating portion 412 is an inclined surface. The distance between the inclined surface and the first abutting portion 411 gradually decreases from the side close to the first abutting portion 411 toward the side away from the first abutting portion 411.

[0074] In this embodiment, by gradually reducing the size of the clamping portion 413 from the side close to the first supporting portion 411 toward the side away from the first supporting portion 411, it is convenient for the clamping portion 413 to be clamped into the first through hole 32 when the first connecting member 41 is assembled on the decorative member 30. When the first connecting member 41 is installed on the decorative member 30, the clamping portion 413 can be well clamped to the decorative member 30 and is not easy to fall off.

[0075] See also Figure 9 In some embodiments, the first penetration portion 412 has a central axis, and the angle α between the surface of the clamping portion 413 facing away from the first penetration portion 412 and the central axis is in the range of 15°≤α≤60°.

[0076] Optionally, the first penetration portion 412 is cylindrical, and a central axis of the first penetration portion 412 is perpendicular to the first supporting portion 411 .

[0077] Specifically, the angle α between the surface of the clamping portion 413 facing away from the first passing portion 412 and the central axis can be, but is not limited to, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. If the angle α between the surface of the clamping portion 413 facing away from the first passing portion 412 and the central axis is too small, when the first connecting member 41 is assembled to the decorative member 30, the surface of the clamping portion 413 facing the first abutting portion 411 is difficult to well abut against the inner side wall of the accommodating cavity 31, and the first connecting member 41 is likely to become loose or even come off, affecting the stability of the assembly of the first connecting member 41 and the decorative member 30; if the angle α between the surface of the clamping portion 413 facing away from the first passing portion 412 and the central axis is too large, it is not conducive to the assembly of the first connecting member 41 to the decorative member 30. When the first connecting member 41 is assembled to the decorative member 30, a relatively large force needs to be applied, which may cause deformation of the decorative member 30 or the first connecting member 41, or even damage the decorative member 30 or the first connecting member 41 cannot be snapped into the decorative member 30. In other words, the larger the inclination angle of the angle α between the surface of the clamping portion 413 facing away from the first passing portion 412 and the central axis, the greater the interference amount, resulting in more difficult snapping of the parts. When the range of the angle α between the surface of the clamping portion 413 facing away from the first passing portion 412 and the central axis is: 15° ≤ α ≤ 60°, it can not only facilitate the embedding of the first connecting member 41 into the decorative member 30, but also enable the first connecting member 41 to have better connection stability with the decorative member 30 when the first connecting member 41 is embedded in the decorative member 30.

[0078] Please refer to Figure 5 and Figure 7 , in one embodiment, the connecting assembly 40 further includes an elastic member 43. The elastic member 43 is located on the side of the vehicle door sheet metal 10 facing the decorative member 30 and between the sealing member 20 and the vehicle door sheet metal 10, and is disposed around the outer periphery of the connecting assembly 40; the range of the compressible amount of the elastic member 43 is 20% to 30%.

[0079] The elastic member 43 is located on the side of the vehicle door sheet metal 10 facing the decorative member 30 and between the sealing member 20 and the vehicle door sheet metal 10, and is disposed around the outer periphery of the connecting assembly 40. It can be understood that the elastic member 43 is disposed around the outer periphery of the second passing portion 422.

[0080] In this embodiment, the second passing portion 422 sequentially passes through the vehicle door sheet metal 10, the elastic member 43, the sealing member 20 and the decorative member 30 to tightly connect the decorative member 30 and the vehicle door sheet metal 10.

[0081] Optionally, the elastic member 43 can be at least one of, but is not limited to, rubber parts, springs, etc.

[0082] In this embodiment, the connecting assembly 40 further includes an elastic member 43. The elastic member 43 is disposed between the seal member 20 and the vehicle door sheet metal 10 to reduce the impact between the seal member 20 and the vehicle door sheet metal 10. In addition, when the door assembly 100 is applied to a vehicle and it is necessary to adjust the step difference between the trim members 30 of two adjacent door assemblies 100, only the second connecting member 42 needs to be turned so that the trim member 30 sequentially presses the seal member 20 and the elastic member 43. Since the elastic member 43 has a compression amount, the elastic member 43 can be compressed, so that the distance between the trim member 30 and the vehicle door sheet metal 10 is reduced. Conversely, the second connecting member 42 can also be loosened so that the compression of the seal member 20 and the elastic member 43 by the trim member 30 is reduced, thereby increasing the distance between the trim member 30 and the vehicle door sheet metal 10. By the cooperation of the first connecting member 41, the second connecting member 42 and the elastic member 43, the distance between the trim member 30 and the vehicle door sheet metal 10 can be adjusted, so that the step difference between the trim members 30 of at least two adjacent door assemblies 100 can be adjusted.

[0083] Optionally, the range of the compressible amount of the elastic member 43 is 20% to 30%.

[0084] Specifically, the compressible amount of the elastic member 43 may be, but is not limited to, 20%, 22%, 24%, 26%, 28%, 30%, etc.

[0085] By controlling the magnitude of the compressible amount and the resilience amount of the elastic member 43, the step difference of the trim member 30 can be adjusted. As the depth of the second connecting member 42 screwed into the first connecting member 41 increases, the pressure exerted by the connecting assembly 40 on the elastic member 43 is greater, the generated compression amount is also greater, and the resilience amount is also greater. If the compressible amount of the elastic member 43 is too small, the adjustment ability of the step difference of the door assembly 100 is reduced; if the compressible amount of the elastic member 43 is too large, it is easy to make the whole trim member 30 protrude too much, affecting the appearance effect of the door assembly 100.

[0086] Please refer to Figure 11 , in one embodiment, the door assembly 100 further includes a glass member 50. The glass member 50 is movably connected to the vehicle door sheet metal 10 and is disposed on a side of the seal member 20 away from the trim member 30. The seal member 20 includes a body portion 21 and a flocked portion 22. The flocked portion 22 is located on a surface of the body portion 21 facing the glass member 50.

[0087] It can be understood that the glass member 50 can move in a direction away from the vehicle door sheet metal 10 so that the glass member 50 and the vehicle door sheet metal 10 are at least partially staggered; the glass member 50 can also move in a direction close to the vehicle door sheet metal 10 so that the glass member 50 and the vehicle door sheet metal 10 are stacked.

[0088] Optionally, when the glass member 50 is at least partially offset from the door sheet metal 10, the flocked portion 22 abuts against the glass member 50.

[0089] Optionally, the material of the main body portion 21 may be, but is not limited to, a resin material. In a specific embodiment, the material of the main body portion 21 may be, but is not limited to, hard ethylene propylene diene monomer (EPDM).

[0090] Optionally, the material of the flocked portion 22 may be, but is not limited to, fibers. The flocked portion 22 may implant the fibers onto the surface of the main body portion 21 facing the glass member 50 in a flocking manner.

[0091] In this embodiment, by providing the flocked portion 22 on the surface of the main body portion 21 facing the glass member 50, the surface of the seal member 20 facing the glass member 50 can be made smoother, and when the glass member 50 moves relative to the door sheet metal 10 and the seal member 20, the friction between the seal member 20 and the glass member 50 can be better reduced; in addition, by providing the flocked portion 22, the sealing performance of the seal member 20 can be increased, and the waterproof and sealing effects of the door assembly 100 can be improved.

[0092] Optionally, the seal member 20 further includes an insert, which is embedded in the main body portion 21 to improve the mechanical strength of the seal member 20.

[0093] Optionally, the material of the insert may be, but is not limited to, a metal material.

[0094] Please refer to Figure 11 , in some embodiments, the seal member 20 further includes an elastic portion 23, and the elastic portion 23 is located on the surface of the main body portion 21 facing the decorative member 30.

[0095] It can be understood that the elastic portion 23 abuts against the decorative member 30.

[0096] Optionally, the material of the elastic portion 23 may be, but is not limited to, soft ethylene propylene diene monomer.

[0097] Optionally, the elastic portion 23 and the main body portion 21 are of an integral structure, and different ethylene propylene diene monomers may be used for the elastic portion 23 and the main body portion 21, and they are prepared by an integral molding process such as injection molding.

[0098] In this embodiment, the elastic part 23 is disposed between the decorative part 30 and the body part 21, increasing the compressibility of the seal 20. When the adjusting connection assembly 40 is adjusted to adjust the distance between the decorative part 30 and the vehicle door sheet metal 10, due to the existence of the elastic part 23, the seal 20 can also be compressed, thereby increasing the adjustment margin between the decorative part 30 and the seal 20, so that the step difference between at least two vehicle door assemblies 100 can be adjusted within a larger range, and the appearance effect of the vehicle can be improved better. In addition, through the cooperation of the elastic part 23 and the flocking part 22 on the seal 20, the seal 20 can have a better sealing effect, can abut against the decorative part 30 and the glass part 50 more tightly, and can better improve the sealing performance and waterproof effect of the vehicle door assembly 100.

[0099] Please refer to Figure 12 , an embodiment of the present application provides a vehicle 200, which includes: a vehicle body 210 and the vehicle door assembly 100 described in the embodiment of the present application, and the vehicle door assembly 100 is rotatably connected to the vehicle body 210.

The connection assembly 40 sequentially passes through the door sheet metal 10, the seal 20, and the trim 30 to connect the door sheet metal 10, the seal 20, and the trim 30. The door sheet metal 10, the seal 20, and the trim 30 are connected by the connection assembly 40, which can make the connection between the door sheet metal 10, the seal 20, and the trim 30 more stable. When the door assembly 100 is applied to the vehicle 200, it is less likely to become loose and generate abnormal noises. In addition, the relative position between the trim 30 and the seal 20 can be adjusted by the tightening degree of the connection assembly 40, so as to adjust the position of the surface of the trim 30 facing away from the seal 20. When the door assembly 100 is applied to the vehicle 200 and there are at least two door assemblies 100 on the same side of the vehicle 200, the tightening degree of the connection assembly 40 can be adjusted to make the trims 30 on at least two door assemblies 100 flush or smoothly transition, so as to solve the step difference problem of the trims 30 on at least two door assemblies 100 and improve the appearance effect of the vehicle 200.
