[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The utility model embodiment provides a vehicle door assembly, referring to Figure 1 and Figure 2 The door assembly includes a door inner panel 1, an anti-collision rod 2 and a support beam 3; the anti-collision rod 2 is arranged on the door inner panel 1 along the front-rear direction of the vehicle; the support beam 3 is arranged on the door inner panel 1 along the up-down direction of the vehicle; the rear end of the anti-collision rod 2 is connected to the support beam 3.

[0029] As an example, the door assembly can be a front door or a rear door, and when subjected to collision force, the force can be transmitted to the B-pillar or the C-pillar. The door assembly specifically includes a door inner panel 1, an anti-collision bar 2 and a support beam 3; during installation, the anti-collision bar 2 is set on the door inner panel 1 along the front-rear direction of the vehicle, and then the support beam 3 is set on the door inner panel 1 along the up-down direction of the vehicle; when the anti-collision bar 2 of the door is impacted, the anti-collision bar 2 and the support beam 3 cooperate to improve the support strength of the door inner panel 1, decompose the impact energy on the door inner panel 1, avoid deformation concentrated on the rear of the door assembly, and effectively reduce the intrusion speed to prevent the occupants from being injured. In this example, the rear end of the anti-collision bar 2 is connected to the support beam 3, which can be connected by a connector or by a large-area overlap; the force on the anti-collision bar 2 can be transmitted to the support beam 3, and the force transmission is offset by the support beam 3; the support beam 3 is generally made of high-strength material, which can well strengthen the strength of the rear part of the door assembly, and evenly disperse the energy of the anti-collision bar 2 to other places, so that the impact energy at the rear of the door is reduced, and the intrusion speed in the car is reduced. Among them, the rear end of the anti-collision bar 2 corresponds to the seat cushion position of the seat. By connecting the support beam 3 to the rear end of the anti-collision bar 2, the impact energy can be avoided from being concentrated on the rear part of the door, that is, the impact energy can be avoided from being concentrated in the area corresponding to the seat cushion position of the door and the seat. For example, when a person sits on a seat, the position of the rear end of the anti-collision bar 2 overlaps with the position of the person's pelvis, which can prevent the person's pelvis from being injured.

[0030] In one embodiment, referring to Figure 1 and Figure 2 The anti-collision bar 2 gradually tilts downward along the front-rear direction of the vehicle; the front end of the anti-collision bar 2 overlaps the front side of the door inner panel 1, and the rear end of the anti-collision bar 2 overlaps the rear side of the door inner panel 1.

[0031] As an example, the anti-collision bar 2 gradually tilts downward along the front-to-back direction of the vehicle, so that when the anti-collision bar 2 transmits the collision force from front to back, it can also transmit the collision force from top to bottom, which is convenient for transmitting the force to the door sill, thereby improving the supporting strength of the door assembly. During installation, the front end of the anti-collision bar 2 is overlapped on the front side of the door inner panel 1, and the rear end of the anti-collision bar 2 is overlapped on the rear side of the door inner panel 1; in this way, the force on the anti-collision bar 2 can be transmitted to the support beam 3, and the force transmission is offset by the support beam 3; the support beam 3 is generally made of high-strength material, and the rear end of the anti-collision bar 2 is connected to the support beam 3, so that the rigidity of the rear part of the door is strengthened, the deformation is concentrated on the front part of the door, the impact energy at the rear is reduced, and the intrusion speed in the vehicle is also reduced.

[0032] In one embodiment, referring to Figure 1 and Figure 2 The door inner panel 1 includes a rear side of the inner panel; the support beam 3 is overlapped on the rear side of the inner panel; the rear end of the anti-collision rod 2 is overlapped with the lower end or the middle part of the support beam 3.

[0033] As an example, the door inner panel 1 includes a rear side of the inner panel, which corresponds to the structural column (B-pillar or C-pillar) of the vehicle body, and the rear side of the inner panel is arranged along the up-down direction of the vehicle; the support beam 3 is overlapped on the rear side of the inner panel, so that the support beam 3 can strengthen the rigidity of the rear side of the inner panel, transfer the impact energy to the corresponding structural column (B-pillar or C-pillar), and reduce the impact energy of the door. There are two situations in which the support beam 3 overlaps the rear end of the anti-collision bar 2. The first situation is: the lower end of the support beam 3 overlaps the rear end of the anti-collision bar 2; the second situation is: the middle part of the support beam 3 overlaps the rear end of the anti-collision bar 2. In this way, the rear end of the anti-collision bar 2 is connected to the support beam 3, so that the rigidity of the rear part of the door is strengthened, and the support beam 3 can evenly disperse the impact energy at the rear end of the anti-collision bar 2, so that the deformation is concentrated in the front part of the door, and the impact energy at the rear is reduced, so as to avoid the impact energy being concentrated in the rear part of the door, that is, to avoid the impact energy being concentrated in the area corresponding to the position of the door and the seat cushion of the seat. For example, when a person sits on the seat, the rear end of the anti-collision bar 2 overlaps with the pelvis of the person, thereby reducing the speed of pelvic intrusion and preventing the pelvis from being injured.

[0034] In one embodiment, referring to Figure 1 When the door inner panel 1 is a rear door inner panel, the rear side of the inner panel is arc-shaped.

[0035] As an example, when the door inner panel 1 is a rear door inner panel, the rear side of the inner panel is arc-shaped, which can avoid the rear wheels. At the same time, the arc-shaped rear side can increase the force transmission path and improve its ability to resist collision force.

[0036] In one embodiment, referring to Figure 1 The projection of the support beam 3 along the left-right direction of the vehicle at least partially overlaps with the projection of the seat back along the left-right direction of the vehicle.

[0037] As an example, the projection of the support beam 3 along the left-right direction of the vehicle at least partially overlaps with the projection of the seat back along the left-right direction of the vehicle. That is to say, in the left-right direction of the vehicle, the support beam 3 can at least partially overlap with the upper body of the person on the seat. The support beam 3 has high strength and can improve the supporting strength of the door assembly in the overlapping area, thereby preventing injuries to the occupants.

[0038] In one embodiment, referring to Figure 1 and Figure 2 The anti-collision rod 2 includes a first main body 21, a first overlapping portion 22 extending from the front end of the first main body 21, and a second overlapping portion 23 extending from the rear end of the first main body 21; the first overlapping portion 22 is overlapped on the door inner panel 1; the second overlapping portion 23 is overlapped between the rear end of the door inner panel 1 and the support beam 3, or the second overlapping portion 23 is overlapped on the support beam 3.

[0039] As an example, the anti-collision bar 2 includes a first main body 21, a first overlapping portion 22 and a second overlapping portion 23; the first main body 21 is arranged along the front and rear direction of the vehicle; the first overlapping portion 22 extends from the front end of the first main body 21, and is specifically overlapped on the front end of the door inner panel 1; the second overlapping portion 23 extends from the rear end of the first main body 21, and is specifically overlapped between the rear end of the door inner panel 1 and the support beam 3, or, the support beam 3 is first set on the door inner panel 1, and then the second overlapping portion 23 is overlapped on the support beam 3; such an arrangement can make the installation of the anti-collision bar 2 more secure and stable, make the overlapping surface between it and the door inner panel 1 and the support beam 3 larger, and increase the connection strength.

[0040] In one embodiment, referring to Figure 1 and Figure 2 The support beam 3 includes a second main body 31 and a third overlapping portion 32, and the third overlapping portion 32 is arranged on the lower end or the middle part of the second main body 31; the second main body 31 is arranged on the door inner panel 1 along the up and down direction of the vehicle, and the rear end of the anti-collision rod 2 is overlapped between the door inner panel 1 and the third overlapping portion 32, or the rear end of the anti-collision rod 2 is overlapped on the third overlapping portion 32.

[0041] As an example, the support beam 3 includes a second main body 31 and a third overlapping portion 32; the second main body 31 is arranged on the door inner panel 1 along the up and down direction of the vehicle, specifically on the rear side of the inner panel of the door inner panel 1, corresponding to the structural column (B-pillar or C-pillar) of the vehicle body, so that the support beam 3 can be used to strengthen the rigidity of the rear side of the inner panel, transfer the impact energy to the corresponding structural column (B-pillar or C-pillar), and reduce the impact energy of the door; the third overlapping portion 32 is arranged on the lower end or middle part of the second main body 31, and the rear end of the anti-collision rod 2 is overlapped between the door inner panel 1 and the third overlapping portion 32, or the rear end of the anti-collision rod 2 is overlapped on the third overlapping portion 32; specifically, the third overlapping portion 32 is overlapped on the door inner panel 1 Between the rear end and the support beam 3, or, first set the support beam 3 on the door inner panel 1, and then overlap the second overlap portion 23 on the support beam 3; such a setting can make the installation of the anti-collision bar 2 more secure and stable, make the overlap surface between it and the door inner panel 1 and the support beam 3 larger, increase the connection strength between the support beam 3 and the anti-collision bar 2, so that the support beam 3 and the anti-collision bar 2 are superimposed to strengthen the rigidity of the rear part of the door, and the support beam 3 can evenly disperse the impact energy at the rear end of the anti-collision bar 2, so that the deformation is concentrated in the front part of the door, and the impact energy at the rear part is reduced, avoiding the impact energy from being concentrated in the rear part of the door, that is, avoiding the impact energy from being concentrated in the area corresponding to the position of the door and the seat cushion of the seat. For example, when a person sits on a seat, the position of the rear end of the anti-collision bar 2 overlaps with the position of the pelvis of the person, reducing the speed of pelvic invasion and avoiding damage to the pelvis of the person.

[0042] An embodiment of the utility model provides a car, comprising a door assembly.

[0043] As an example, the door assembly can be a front door or a rear door, and when subjected to collision force, the force can be transmitted to the B-pillar or the C-pillar. The door assembly specifically includes a door inner panel 1, an anti-collision bar 2 and a support beam 3; during installation, the anti-collision bar 2 is set on the door inner panel 1 along the front-rear direction of the vehicle, and then the support beam 3 is set on the door inner panel 1 along the up-down direction of the vehicle; when the anti-collision bar 2 of the door is impacted, the anti-collision bar 2 and the support beam 3 cooperate to improve the support strength of the door inner panel 1, decompose the impact energy on the door inner panel 1, avoid deformation concentrated on the rear of the door assembly, and effectively reduce the intrusion speed to prevent occupants from being injured. In this example, the rear end of the anti-collision bar 2 is connected to the support beam 3, which can be connected by a connector or by a large-area overlap; in this way, the force on the anti-collision bar 2 can be transmitted to the support beam 3, and the force transmission is offset by the support beam 3; the support beam 3 is generally made of high-strength material, which can well strengthen the strength of the rear part of the door assembly, and evenly decompose the energy of the anti-collision bar 2 to other places, so that the rigidity of the rear part of the door is strengthened, the deformation is concentrated in the front part of the door, the impact energy of the rear part is reduced, and the intrusion speed in the car is also reduced. Among them, the rear end of the anti-collision bar 2 corresponds to the seat cushion position of the seat. By connecting the support beam 3 to the rear end of the anti-collision bar 2, the impact energy can be avoided from being concentrated in the rear part of the door, that is, the impact energy can be avoided from being concentrated in the area corresponding to the seat cushion position of the door and the seat. For example, when a person sits on a seat, the position of the rear end of the anti-collision bar 2 overlaps with the position of the person's pelvis, which can prevent the person's pelvis from being injured.
