[0029] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0030] Reference below Figure 1-Figure 8 A vehicle door assembly according to an embodiment of the present utility model is described.

[0031] As car doors increase in size, their angular stiffness will deteriorate. If the stiffness is insufficient, it will cause deformation, affecting the appearance gap, surface difference and flatness. If the deformation increases further, it will affect the sealing performance with the sealing strip, causing water leakage, air leakage and high-speed vibration problems. Currently, most car doors use high-strength materials to improve door strength, but door deformation still occurs.

[0032] Therefore, the utility model proposes a vehicle door assembly to solve the above-mentioned technical problems.

[0033] like Figure 1-Figure 4 As shown, the door assembly includes: a door window frame 1 and a door window frame reinforcement plate 2, the door window frame reinforcement plate 2 is arranged on the side of the door window frame 1 facing the interior of the vehicle, the door window frame reinforcement plate 2 is fixedly connected to the door window frame 1, and together define a cavity 3, and the cavity 3 is extended along the height direction and / or length direction of the entire vehicle.

[0034] In this arrangement, the door window frame 1 and the door window frame reinforcement plate 2 are fixedly connected and jointly define a cavity 3. The cavity 3 can extend in the height direction of the entire vehicle and can also extend in the length direction of the entire vehicle, so that the strength of the cavity 3 is increased. By utilizing the high strength of the cavity 3, the rigidity of the door assembly can be improved and the bending resistance of the door assembly can be enhanced.

[0035] In some embodiments of the present invention, the vehicle door window frame 1 and the vehicle door window frame reinforcement plate 2 are both metal sheet metal parts, which can ensure the strength of the vehicle door window frame 1.

[0036] In some embodiments of the present invention, the vehicle door window frame 1 and / or the vehicle door window frame reinforcement plate 2 are integral stamping parts. When the vehicle door window frame 1 is an integral stamping part, it is convenient to control the overall strength and quality of the vehicle door window frame 1, and it is convenient to process the vehicle door window frame 1. When the vehicle door window frame reinforcement plate 2 is an integral stamping part, it is convenient to control the overall strength and quality of the vehicle door window frame reinforcement plate 2, and it is convenient to process the window frame reinforcement plate 2.

[0037] Therefore, according to the vehicle door assembly of the present invention, the cavity 3 is jointly defined by the vehicle door window frame 1 and the vehicle door window frame reinforcement plate 2, so that the rigidity of the vehicle door window frame 1 can be improved and the bending resistance of the vehicle door window frame 1 can be enhanced. When the vehicle door window frame 1 is applied to a vehicle, it is beneficial to reduce or avoid deformation or shaking generated during the door closing process or the vehicle driving process.

[0038] like Figure 1 and 2 As shown, the door window frame reinforcement plate 2 is arranged at the connection between the rear side window frame in the door window frame 1 and the lower window frame in the door window frame 1, and one end of the door window frame reinforcement plate 2 along the height direction of the whole vehicle extends to the outside of the lower edge of the lower window frame in the door window frame 1.

[0039] Specifically, the door window frame 1 includes an upper window frame, a rear side window frame, a lower window frame and a front side window frame which are connected in sequence. The door window frame reinforcement plate 2 is arranged at the connection between the rear side window frame and the lower window frame in the door window frame 1, which can improve the lateral stiffness of the door assembly, thereby further improving the deformation or shaking of the door when opening the door or during the driving of the vehicle.

[0040] In some specific embodiments of the present invention, the door window frame 1 is a front door window frame 1, and the door window frame reinforcement plate 2 is arranged at the connection between the B-pillar window frame and the lower window frame in the door window frame 1, thereby improving the lateral rigidity of the door assembly.

[0041] Of course, the door window frame 1 may also be a rear door window frame 1, and the door window frame reinforcement plate 2 may be arranged at the connection between the C-pillar window frame and the lower window frame in the door window frame 1. That is, the door window frame reinforcement plate 2 is arranged at a side away from the hinged connection between the door and the body, so that when a Y-direction load is applied to the door, the door assembly itself can resist deformation.

[0042] According to some specific embodiments of the present invention, see Figure 2 As shown, the vehicle door window frame reinforcement plate 2 includes: a first plate portion 201 and a second plate portion 202. The first plate portion 201 is arranged at the rear side window frame in the vehicle door window frame 1, and one end of the first plate portion 201 along the height direction of the whole vehicle extends downward to the outside of the lower edge of the vehicle door window frame 1. The second plate portion 202 is arranged at the lower window frame in the vehicle door window frame 1, and the second plate portion 202 is connected to one side of the first plate portion 201 along the length direction of the whole vehicle, and the first plate portion 201 and the vehicle door window frame 1 define a cavity 3.

[0043] Specifically, the first plate portion 201 is arranged at the rear window frame of the vehicle door window frame 1, and one end of the first plate portion 201 along the vehicle height direction extends downward to the outside of the lower edge of the vehicle door window frame 1, thereby enhancing the lateral rigidity of the rear position of the vehicle door assembly. Among them, the part of the first plate portion 201 extending downward to the outside of the lower edge of the vehicle door window frame 1 along the vehicle height direction can be connected to other structural parts, thereby improving the structural strength of the vehicle door window frame reinforcement plate 2.

[0044] In addition, the second plate portion 202 is arranged on the lower window frame of the door window frame 1 and is connected to one side of the first plate portion 201 along the length direction of the entire vehicle, which can improve the connection strength between the first plate portion 201 and the door window frame 1, and at the same time can enhance the structural strength of the lower window frame of the door assembly, thereby enhancing the lateral stiffness of the rear side of the door assembly.

[0045] The first plate portion 201 and the door window frame 1 define a cavity 3, so that the cavity 3 can extend along the height direction of the entire vehicle. The larger the cavity 3, the higher the strength, which further improves the lateral stiffness of the rear side of the door window frame 1. When the door assembly is used in a vehicle, it is further helpful to reduce or avoid the shaking generated during the door closing process or the vehicle driving process.

[0046] Furthermore, a plurality of first welding holes 203 are respectively provided at both ends of the door window frame reinforcement plate 2 along the length direction of the entire vehicle, so as to be fixedly connected to the door window frame 1 through the first welding holes 203 .

[0047] See Figure 2 As shown, the door window frame reinforcement plate 2 is respectively provided with a plurality of first welding holes 203 at both ends along the length direction of the whole vehicle, and the plurality of first welding holes 203 are arranged at intervals along the height direction of the whole vehicle. The door window frame reinforcement plate 2 is welded to the door window frame 1 through the plurality of first welding holes 203, which can ensure that the door window frame reinforcement plate 2 and the door window frame 1 are firmly welded, thereby enhancing the rigidity of the door window frame 1 and the bending resistance of the door window frame 1. When the door assembly is applied to a vehicle, it is beneficial to reduce or avoid the shaking generated during the door closing process or the vehicle driving process.

[0048] Furthermore, a first positioning portion is provided on the vehicle door window frame reinforcement plate 2 , and a second positioning portion is provided on the vehicle door window frame 1 , and the first positioning portion is positioned and matched with the second positioning portion.

[0049] In this way, before the door window frame reinforcement plate 2 and the door window frame 1 are welded, they are first positioned and matched by the first positioning portion and the second positioning portion to achieve pre-installation, and then the two are welded and fixed.

[0050] In some embodiments, the first positioning portion may be one of a positioning hole and a positioning pin, and the second positioning portion may be the other of a positioning hole and a positioning pin, and the positioning pin is inserted into the positioning hole to achieve positioning fit.

[0051] Further, see Figure 3 The two ends of the door window frame 1 include a first connection part 101 and a second connection part 102, and the two ends of the door window frame reinforcement plate 2 include a third connection part 204 and a fourth connection part 205. The first connection part 101 and the third connection part 204 are overlap-welded, and the second connection part 102 and the fourth connection part 205 are overlap-welded to form a closed chamber between the door window frame 1 and the door window frame reinforcement plate 2.

[0052] Furthermore, the vehicle door assembly further includes: a reinforcement member 4 , which is disposed in the cavity 3 , and is fixedly connected to the vehicle door window frame reinforcement plate 2 and / or the vehicle door window frame 1 .

[0053] See Figure 4 As shown, a reinforcement member 4 is arranged in a cavity 3 defined by a door window frame 1 and a door window frame reinforcement plate 2, so that the reinforcement member 4, the door window frame reinforcement plate 2 and the door window frame 1 are connected as a whole, thereby improving the structural strength and rigidity of the door assembly, thereby improving the stability of the door assembly, thereby reducing or avoiding the shaking of the door during closing and opening, and reducing or avoiding the shaking of the door during driving of the vehicle.

[0054] Furthermore, both ends of the reinforcement member 4 are connected to the door window frame reinforcement plate 2 , and both the reinforcement member 4 and the door window frame reinforcement plate 2 are raised in a direction away from the door window frame 1 .

[0055] See Figure 4 As shown, both ends of the reinforcement member 4 overlap the side walls of the door window frame reinforcement plate 2 located in the cavity 3, and the reinforcement member 4 and the door window frame reinforcement plate 2 are both protruded away from the door window frame 1, so that the cavity 3 forms two "arch structure" chambers. By utilizing the high strength of the "arch structure", the strength of the cavity 3 can be further enhanced, thereby further improving the lateral stiffness of the door assembly and further enhancing the bending resistance of the door assembly.

[0056] According to some specific embodiments of the present invention, the reinforcement member 4 is located at the connection between the rear side window frame and the lower window frame in the vehicle door window frame 1 to enhance the lateral stiffness of the connection portion of the vehicle door window frame 1 located at the rear side window frame and the lower window frame, thereby ensuring the overall stiffness of the vehicle door assembly.

[0057] In addition, the door assembly also includes: a sound insulation member, which is arranged in the cavity 3. Such an arrangement can effectively prevent the flowing air from flowing in and out of the cavity 3 of the door window frame 1 through the sheet metal hole during the driving of the car, and prevent the flowing air from penetrating each other, thereby effectively reducing or even preventing the sound from jumping in the cavity 3 to cause resonance and form high-frequency noise to be transmitted to the ears of people in the car, thereby improving the user's comfort experience.

[0058] Furthermore, the vehicle door assembly further includes: a vehicle door inner panel 5 , which is arranged on the side of the vehicle door window frame reinforcement plate 2 facing the vehicle interior, and the vehicle door inner panel 5 is fixedly connected to the vehicle door window frame 1 and / or the vehicle door window frame reinforcement plate 2 .

[0059] refer to Figure 5 and Figure 6 In the direction from the outer side to the inner side of the vehicle, the door window frame 1, the door window frame reinforcement plate 2 and the door inner panel 5 are arranged in sequence. The door inner panel 5 serves as a carrier of the door assembly. By fixing the door window frame 1 and the door window frame reinforcement plate 2 to the upper part of the door inner panel 5, the structural strength of the door window frame reinforcement plate 2 and the door window frame 1 can be further guaranteed, thereby further improving the lateral stiffness of the upper part of the door assembly.

[0060] Furthermore, the vehicle door assembly further includes: an outer panel reinforcement plate 6 , which is arranged on the side of the vehicle door window frame 1 facing the outside of the vehicle, and the outer panel reinforcement plate 6 is fixedly connected to the vehicle door window frame 1 and / or the vehicle door window frame reinforcement plate 2 .

[0061] refer to Figure 7 and Figure 8In the direction from the outside of the vehicle to the inside of the vehicle, the outer panel reinforcement plate 6, the door window frame 1, the door window frame reinforcement plate 2 and the door inner panel 5 are arranged in sequence. The outer panel reinforcement plate 6 mainly provides support for the door outer panel. By being fixedly connected with the door window frame 1 and the door window frame reinforcement plate 2, the structural strength of the door window frame reinforcement plate 2 and the door window frame 1 can be further guaranteed, thereby further improving the lateral stiffness of the upper part of the door assembly.

[0062] Further, a plurality of second welding holes are provided on the door inner panel 5, and at least a portion of the plurality of second welding holes are spaced apart in the height direction of the whole vehicle. The door inner panel 5 is welded to the door window frame 1 and / or the door window frame reinforcement plate 2 through the plurality of second welding holes to form a first welding point 7; and / or, a plurality of third welding holes are provided on the outer panel reinforcement plate 6, and at least a portion of the plurality of third welding holes are spaced apart in the height direction of the whole vehicle.

Figure 6 The door inner panel 5, the door window frame 1 and the door window frame reinforcement plate 2 are welded to form a plurality of first welding points 7. That is, from the Y direction, the welding points are arranged in the Z direction to compensate for the problem of weak corner stiffness caused by the upper end of the door itself being subjected to force and the weak connection structure at the lower end.

[0064] refer to Figure 7 and Figure 8 The outer panel reinforcement plate 6 is provided with a plurality of third welding holes (not shown in the drawings), at least a portion of which are arranged at intervals along the height direction of the vehicle, and the outer panel reinforcement plate 6 is welded to the door window frame 1 and the door window frame reinforcement plate 2 through the plurality of third welding holes to form a three-layer weld, ensuring that the outer panel reinforcement plate 6, the door window frame 1 and the door window frame reinforcement plate 2 are firmly connected. Figure 8 The outer panel reinforcement plate 6, the door window frame 1 and the door window frame reinforcement plate 2 are welded to form a plurality of second welding points 8, so that when the upper end of the door is deformed by force, the force can be transmitted to the door window frame reinforcement plate 2 through the welding points to resist deformation.

[0065] The above welding method can adopt laser welding, which has the characteristics of high precision, high speed, small deformation, small heat-affected zone, etc., and can protect the welding quality of the door assembly.
