The vehicle door and the vehicle provided by the embodiment of the present application are described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1 to 4, an embodiment of the present invention provides a vehicle door, which is applied to an automobile and includes an outer panel 100, an inner panel 200, a window frame reinforcing panel 300, and an impact beam 400, wherein the outer panel 100 is mainly used for protecting the structures such as the window frame reinforcing panel 300 and the impact beam 400, and meanwhile, the outer panel 100 is used as an exterior part of the vehicle door and needs to meet the requirement of modeling. The door has been seted up the door window, and the door window is used for satisfying the daylighting in the car, ventilates and the demand of passenger's field of vision, and window frame reinforcing plate 300 is located the edge of door window for strengthen the intensity at door window edge. Alternatively, the window frame reinforcing plate 300 may be made of a sheet metal, which is not particularly limited herein. The window frame reinforcing plate 300 is disposed between the outer panel 100 and the inner panel 200, the impact bar 400 is disposed on the window frame reinforcing plate 300, and optionally, the impact bar 400 and the window frame reinforcing plate 300 may be connected by means of adhesion, bolting, or the like, which is not particularly limited herein. The impact beam 400 is located between the window frame reinforcing panel 300 and the inner panel 200, and the impact beam 400 extends in the traveling direction of the automobile, i.e., the longitudinal direction of the impact beam 400 is parallel to the longitudinal direction of the automobile. Alternatively, the vehicle door in the embodiment of the present application may be a left front door, a right front door, a left rear door, or a right rear door of an automobile, and may of course be another type of vehicle door, where the specific type of the vehicle door is not particularly limited.

Through set up crash bar 400 on window frame reinforcing plate 300 to improve the crashproof performance of door, when the car takes place the side impact, this crash bar 400 can reduce the deflection that the door received after the collision, and then provides great living space for the interior passenger of car. Therefore, the problem that the anticollision performance of present door is relatively poor can be solved to this application embodiment.

The impact beam 400 may be a solid beam, and since the weight and cost of the solid beam are large, the impact beam 400 may be optionally a hollow beam, thereby reducing the weight and cost of the impact beam 400. Further alternatively, when the impact beam 400 is a hollow beam, the wall thickness of the hollow beam may be 2.5mm, thereby ensuring the strength of the impact beam 400 while achieving a good weight reduction effect, but the wall thickness of the hollow beam may be other values, which is not particularly limited herein.

Optionally, the crash bar 400 is a steel structure, which has the characteristics of high material strength, light weight, good plasticity, uniform material quality and high structural reliability, and the steel structure is suitable for bearing impact and dynamic load and has good seismic performance. Further alternatively, the impact beam 400 may be made of cold-rolled high-strength steel having a rigidity of 1.5G Mpa, but the impact beam 400 may also be made of hot-formed high-strength steel, which is not particularly limited herein.

In an alternative embodiment, the height of the crash bar 400 in the height direction of the vehicle may be equal to the width of the crash bar 400 in the width direction of the vehicle, in which case the crash bar 400 may have a cylindrical structure or a prismatic structure, in which case if the cross-sectional area of the crash bar 400 is smaller, the strength of the crash bar 400 is smaller, and the crashworthiness thereof is poorer; if the cross-sectional area of the impact beam 400 is large, the impact beam 400 occupies a large space in the width direction of the vehicle, and in this case, the dimensions of other parts of the vehicle door in the width direction need to be adjusted accordingly, which increases the difficulty of design and also results in a large thickness of the vehicle door. Therefore, alternatively, the minimum height of the impact beam 400 in the height direction of the automobile is larger than the maximum width of the impact beam 400 in the width direction of the automobile, and the impact beam 400 may have a plate-shaped structure with a certain thickness, and the cross-sectional shape thereof may be a bar shape, an oval shape, and the like, which is not particularly limited herein. Therefore, the crash bar 400 adopting the structure in the embodiment of the present application can reduce the space occupied by the crash bar in the width direction of the automobile, so as to reduce the design difficulty and facilitate reducing the thickness of the door. Of course, in the embodiment in which the impact beam 400 is a hollow beam, the minimum height of the impact beam 400 in the height direction of the automobile may also be greater than the maximum width of the impact beam 400 in the width direction of the automobile, thereby reducing the space occupied by the impact beam 400 in the width direction of the automobile to reduce the thickness of the door.

In a further alternative embodiment, the opposite side of the impact beam 400 and the window frame reinforcing plate 300 is the first side 410, the first side 410 includes a first arc-shaped surface 411 and a second arc-shaped surface 413 which are connected, the window frame reinforcing plate 300 may be connected to the first arc-shaped surface 411, the window frame reinforcing plate 300 may also be connected to the second arc-shaped surface 413, the window frame reinforcing plate 300 may also be connected to the connection between the first arc-shaped surface 411 and the second arc-shaped surface 413, but no matter which connection manner is adopted, the connection area between the impact beam 400 and the window frame reinforcing plate 300 is smaller, and the connection stability of the impact beam 400 is poorer. Therefore, optionally, the impact beam 400 further includes a plane 412, the first arc-shaped surface 411, the plane 412 and the second arc-shaped surface 413 are sequentially connected, and the plane 412 is connected to the window frame reinforcing plate 300, at this time, the connection area between the impact beam 400 and the window frame reinforcing plate 300 is large, which is beneficial to improving the connection stability of the impact beam 400. Alternatively, the impact beam 400 may have a symmetrical structure, and the surface of the impact beam 400 opposite to the inner panel 200 has the same shape as the first surface 410, so as to facilitate the fabrication of the impact beam 400.

In an alternative embodiment, in the driving direction of the automobile, the length of the impact bar 400 may be smaller than the maximum width of the window, and at this time, the impact bar 400 is shorter, and only a part of the door has better impact resistance, and when the automobile has a side impact, the impact resistance of the door is not good enough. Therefore, optionally, the length of the impact beam 400 is smaller than the maximum width of the vehicle door, and the length of the impact beam 400 is larger than the maximum width of the vehicle window, so that the length of the impact beam 400 is increased as much as possible to increase the impact area of the vehicle door, thereby improving the impact resistance of the vehicle door. Further alternatively, the length of the crash bar 400 may be 920mm, but the length of the crash bar 400 may also be selected according to practical needs, and is not particularly limited herein.

In an alternative embodiment, the door further includes a hinge reinforcement plate 500 and an impact beam 600, and the hinge reinforcement plate 500 may be made of sheet metal, but may be made of other structures, which is not particularly limited herein. Alternatively, the impact beam 600 may be made of a high strength steel having a stiffness of 2.0G Mpa through hot forming, but the impact beam 600 may also be made of a high strength steel having a cold rolling, which is not particularly limited herein. The hinge reinforcing plate 500 is disposed on the inner panel 200, the hinge reinforcing plate 500 is disposed at one end of the inner panel 200 hinged to the body of the automobile, the impact beam 600 is disposed between the inner panel 200 and the outer panel 100, one end of the impact beam 600 is connected to the hinge reinforcing plate 500, and the other end of the impact beam 600 is connected to the inner panel 200. The anti-collision beam 600 can also improve the structural strength of the vehicle door, and further achieve the anti-collision effect, so that the area corresponding to the anti-collision structure of the vehicle door can be increased, and the anti-collision performance of the vehicle door can be improved. Optionally, the impact beam 600 is located on one side of the impact beam 400 close to the chassis of the vehicle, that is, the impact beam 400 is located on one side of the impact beam 600 away from the chassis of the vehicle, and at this time, the impact beam 600 and the impact beam 400 are relatively dispersed, which is beneficial to generating a better impact effect in a larger area corresponding to the vehicle door, so as to improve the overall impact performance of the vehicle door.

The length direction of the impact beam 600 may be parallel to the driving direction of the automobile, at this time, the length of the impact beam 600 is smaller, and when the distance between the impact beam 600 and the impact beam 400 is larger, the area between the impact beam 600 and the impact beam 400 of the door is easily depressed; when the distance between the impact beam 600 and the impact beam 400 is small, the region of the door on the side of the impact beam 600 away from the impact beam 400 is easily depressed. Therefore, optionally, the distance between the first end of the impact beam 600 and the impact beam 400 is smaller than the distance between the second end of the impact beam 600 and the impact beam 400, i.e. the distance between the first end of the impact beam 600 and the impact beam 400 is a first distance, and the distance between the second end of the impact beam 600 and the impact beam 400 is a second distance, the first distance being smaller than the second distance, where the first distance and the second distance are both the distance between the impact beam 600 and the impact beam 400 in the direction perpendicular to the impact beam 400. That is, the impact beam 600 is disposed obliquely with respect to the impact beam 400, the length of the impact beam 600 can be increased, and the impact beam 600 can prevent a partial recess of the door when the vehicle is involved in a side collision.

The impact beam 600 and the impact beam 400 may be arranged relatively in the height direction of the door, and the impact beam 600 and the impact beam 400 substantially simultaneously receive an impact force when the vehicle is involved in a side collision. In another alternative embodiment, the impact beam 600 is disposed outside the impact beam 400, that is, the impact beam 600 is closer to the outer panel 100 than the impact beam 400, when the automobile has a side impact, an obstacle contacts the impact beam 600, and once the impact beam 600 deforms, the obstacle contacts the impact beam 400 again, so as to resist the obstacle again, so as to improve the impact resistance of the door, that is, the impact beam 400 is disposed to make the door have a secondary impact-proof function, so as to further protect the passengers in the automobile.

The impact beam 400 and the window frame reinforcing plate 300 may be fixedly connected by bolts, etc., but the bolts need to be drilled in the window frame reinforcing plate 300 and the impact beam 400, and the bolts need to occupy additional space inside the vehicle door. Therefore, in an alternative embodiment, the impact beam 400 is welded to the window frame reinforcing plate 300, thereby avoiding drilling holes in the window frame reinforcing plate 300 and the impact beam 400 and not requiring additional space inside the vehicle door. Alternatively, the impact beam 400 is welded to the window frame reinforcing plate 300 by the arc welding, which has the function of isolating oxygen, nitrogen and water vapor in the air, and can protect the welding pool and the electrode. Of course, the bumper bar 400 and the window frame reinforcing plate 300 may be welded by other welding methods, such as argon arc welding, resistance welding, etc., and are not limited in particular.

Based on the door that this application embodiment disclosed, this application embodiment still discloses an automobile, including door and automobile body, the door is articulated with the automobile body, the door be above arbitrary embodiment the door.
