In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0041] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0042] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0043] Reference below Figures 1-12 The vehicle door 100 according to an embodiment of the present invention is described. The vehicle door 100 can improve the structural strength of the vehicle door anti-collision beam 4, more effectively transmit and disperse the impact force during the column collision, ensure the efficient transmission of the collision speed during the collision process, make the airbag explode in time, thereby reducing the collision intrusion amount, and effectively ensure the safety of the occupants in the passenger compartment.

[0044] like Figures 1-12 As shown, a vehicle door 100 according to an embodiment of the present invention includes: a vehicle door inner panel 1 and a vehicle door outer panel 2 , a vehicle door anti-collision beam 4 and a collision bracket 5 .

[0045] First of all, it should be noted that in a traditional car door structure, when a pillar collision occurs, the collision object 93 directly contacts the car door anti-collision beam 4, and the collision speed is transmitted to the car door inner panel 1 through the car door anti-collision beam 4. In this way, the collision speed is transmitted and dispersed through the car door anti-collision beam 4, resulting in a slower collision speed transmission, and the collision energy is only dispersed and absorbed by the car door anti-collision beam 4, which easily causes the anti-collision beam to separate from the car door inner panel 1. Therefore, the utility model proposes a car door 100 that can solve this problem.

[0046] A door cavity 31 is defined between the door inner panel 1 and the door outer panel 2 , that is, the door inner panel 1 and the door outer panel 2 are spaced a certain distance apart to form the door cavity 31 , which is used to install the door anti-collision beam 4 and other components in the door 100 .

[0047] The door anti-collision beam 4 is installed in the door cavity 31, and the door anti-collision beam 4 extends in the front and rear directions. In this way, the door anti-collision beam 4 can provide additional structural strength, disperse and absorb collision energy when the vehicle collides from the side, so as to reduce the deformation of the door 100 and the damage to the occupants.

[0048] Furthermore, the collision bracket 5 is connected to the door anti-collision beam 4 and the door inner panel 1 respectively, and the door outer panel 2 has a collision area 21, and the distance between the collision area 21 and the collision bracket 5 is smaller than the distance between the collision area 21 and the anti-collision beam.

[0049] Specifically, if Figure 1 As shown, the collision bracket 5 is respectively connected to the door anti-collision beam 4 and the door inner panel 1 to ensure the installation stability of the collision bracket 5. The collision bracket 5 can improve the structural strength of the door anti-collision beam 4. When the vehicle collides from the side, it can more effectively transmit and disperse the impact force, ensuring that the door anti-collision beam 4 does not separate from the door inner panel 1 during the side collision, reducing the collision intrusion amount, and thus further protecting the safety of the passengers.

[0050] Among them, the collision area 21 of the door outer panel 2 is the area on the door outer panel 2 that is hit by the collision object 93. The distance between the collision area 21 and the collision bracket 5 is smaller than the distance between the collision area 21 and the anti-collision beam, that is, the collision bracket 5 is closer to the collision area 21. In this way, when the vehicle collides with the door outer panel 2 from the side, the collision object 93 can first contact the collision bracket 5 and then contact the door anti-collision beam 4. The collision energy is transmitted through the collision bracket 5 faster than the door collision beam 4, that is, the collision bracket 5 first transmits the collision speed to the door inner panel 1, and then the door inner panel 1 can transmit the collision speed to other structural components through deformation, thereby greatly improving the transmission speed of the collision speed, that is, realizing efficient transmission of the collision speed, so that the airbag explodes in time, which can further ensure the safety of the occupants in the passenger compartment.

[0051] According to the vehicle door 100 of the embodiment of the present invention, by providing a collision bracket 5 respectively connected to the vehicle door anti-collision beam 4 and the vehicle door inner panel 1, the structural strength of the vehicle door anti-collision beam 4 can be improved, the impact force during the column collision is more effectively transmitted and dispersed, and the vehicle door anti-collision beam 4 is ensured not to be separated from the vehicle door inner panel 1 during the side collision, thereby reducing the collision intrusion amount. By making the distance between the collision area 21 and the collision bracket 5 smaller than the distance between the collision area 21 and the anti-collision beam, when the column collision occurs, the collision object 93 first contacts the collision bracket 5 and then contacts the vehicle door anti-collision beam 4, thereby changing the transmission path of the collision speed and directly transmitting it to the vehicle door inner panel 1 through the collision bracket 5, realizing efficient transmission of the collision speed, causing the airbag to explode in time, and effectively ensuring the safety of the occupants in the passenger compartment.

[0052] In some embodiments, as Figure 2 、 Figure 7 、 Figure 8 and Figure 9 As shown, the collision bracket 5 includes a first collision bracket 51 and a second collision bracket 52. The orthographic projection of the first collision bracket 51 in the collision area and the orthographic projection of the second collision bracket 52 in the collision area are at least partially overlapped, that is, the first collision bracket 51 and the second collision bracket 52 have a common coverage area on the projection surface of the collision area, as shown in FIG. Figure 5 As shown, the first collision bracket 51 is connected to the outer side of the second collision bracket 52. In this way, when viewed from the outside to the inside of the vehicle, the first collision bracket 41 covers or covers the outer side of the second collision bracket 52. In this way, the second collision bracket 52 can support the first collision bracket 51 to enhance the strength and rigidity of the first collision bracket 51 and prevent the first collision bracket 51 from being excessively deformed due to the impact when it is hit, resulting in a decrease in transmission speed.

[0053] The first collision bracket 51 is arranged opposite to the collision area 21, and at least one of the first collision bracket 51 and the second collision bracket 52 is connected to the door inner panel 1, that is, the first collision bracket 51 can be connected to the door inner panel 1 alone, or the second collision bracket 52 can be connected to the door inner panel 1 alone, or the first collision bracket 51 and the second collision bracket 52 are connected to the door inner panel 1 at the same time, so as to realize the transmission of the collision speed to the door inner panel 1 through the first collision bracket 51 and the second collision bracket 52. Specifically, as Figure 5 As shown, the first collision bracket 51 and the second collision bracket 52 are connected to the door inner panel 1 at the same time. In this way, the overall structural strength of the collision bracket 5 can be improved to avoid the first collision bracket 51 or the second collision bracket 52 from being separated from the door inner panel 1, or being severely deformed, thereby causing a decrease in transmission speed.

[0054] In actual design, the first collision bracket 51 and the second collision bracket 52 can be formed by stamping, which has good processing properties and is easy to adapt to the shape of the vehicle door outer panel 2.

[0055] In some embodiments, the first collision bracket 51 is provided with at least one connecting portion 511, that is, one, two or more connecting portions 511 may be provided, and the connecting portion 511 is connected to the vehicle door anti-collision beam 4. Thus, the connection strength between the first collision bracket 51 and the vehicle door anti-collision beam 4 can be improved, thereby improving the connection stability and reliability between the two, and avoiding the first collision bracket 51 from being separated from the vehicle door anti-collision beam 4 when a collision occurs, thereby ensuring the transmission effect of the collision speed, and at the same time more effectively dispersing and absorbing the collision energy.

[0056] In some embodiments, there are multiple connecting parts 511, that is, the connecting parts 511 can be set to two, three or more. Setting multiple connecting parts 511 can enable the first collision bracket 51 to be connected to the vehicle door anti-collision beam 4 through multiple connecting parts 511, thereby further improving the connection stability and reliability between the first collision bracket 51 and the vehicle door anti-collision beam 4.

[0057] Furthermore, the plurality of connection portions 511 are spaced apart along the length direction of the vehicle door anti-collision beam 4 , so that the first collision bracket 51 is subjected to uniform force, thereby preventing the connection from being broken due to local stress concentration.

[0058] Specifically, if Figure 7 and Figure 8 As shown, two connecting parts 511 are provided on the first collision bracket 51 , and the two connecting parts 511 are distributed at a certain distance along the length direction of the door anti-collision beam 4 , and the first collision bracket 51 is connected to the door anti-collision beam 4 through the two connecting parts 511 .

[0059] In other embodiments, Figure 7 and Figure 8As shown, the connecting portion 511 is provided at the bottom of the first collision bracket 51 and is protruded downward, so that it is convenient to connect downward with the vehicle door anti-collision beam 4 and improve the installation convenience.

[0060] Specifically, if Figure 1 The direction shown in the figure is the front and rear direction of the vehicle, wherein one connecting portion 511 is located at the front end of the first collision bracket 51, and the other connecting portion 511 is located in the middle of the bottom of the first collision bracket 51, and is located at the rear end of the first connecting portion 511, both protruding toward the door anti-collision beam 4 to be connected to the door anti-collision beam 5.

[0061] like Figure 6 As shown, the edge fitting joints between the two first connection parts 511 and the vehicle door anti-collision beam 4 can be connected by welding, for example, by oxygen welding, thereby improving the connection reliability between the first connection part 511 and the vehicle door anti-collision beam 4.

[0062] In some embodiments, the first collision bracket 51 and the second collision bracket 52 are respectively welded to the door inner panel 1 .

[0063] In this way, the connection strength between the first collision bracket 51 and the second collision bracket 52 and the door inner panel 1 can be improved, thereby improving the connection reliability and stability of the first collision bracket 51 and the second collision bracket 52 and the door inner panel 1, improving the ability of the first collision bracket 51 and the second collision bracket 52 to disperse the collision energy, accelerating the transmission of the collision speed, ensuring that the door 100 structure can remain intact during the collision, and reducing the degree of damage to passengers caused by the collision.

[0064] In other embodiments, the first collision bracket 51 and the second collision bracket 52 are connected by welding.

[0065] In this way, the connection strength between the first collision bracket 51 and the second collision bracket 52 can be guaranteed, thereby improving the connection reliability and stability between the first collision bracket 51 and the second collision bracket 52, so that the second collision bracket 52 can better support the second collision bracket 52, and then during the collision process, when the collision object 93 first contacts the first collision bracket 51, the first collision bracket 51 is prevented from being severely deformed or falling off, affecting the transmission of the collision speed.

[0066] In some embodiments, at least portions of the first collision bracket 51 and the second collision bracket 52 are spaced apart from each other, and a bracket energy absorbing cavity 61 is defined between the first collision bracket 51 and the second collision bracket 52 .

[0067] Specifically, if Figure 7-Figure 9As shown, the length of the first collision bracket 51 is greater than that of the second collision bracket 52. The second collision bracket 52 is connected to the rear half of the first collision bracket 51 to support the rear half of the first collision bracket 51. The first collision bracket 51 and the second collision bracket 52 are relatively located at a certain interval in the middle, as shown in FIG. Figure 2 As shown, the middle part of the first collision bracket 51 protrudes outward, and the middle part of the second collision bracket 52 protrudes inward, so that a certain space area is separated between the first collision bracket 51 and the second collision bracket 52 to form a bracket energy absorption cavity 61. The bracket energy absorption cavity 61 is used to absorb collision energy. When the vehicle collides and acts on the first collision bracket 51 and the second collision bracket 52, part of the impact force can be converted into deformation energy of the two collision brackets 5, so that the impact force is dispersed between the two collision brackets 5, thereby reducing the impact force borne by a single collision bracket 5, and also reducing the impact force borne by the door anti-collision beam 4 to a certain extent, thereby extending the service life of the first collision bracket 51, the second collision bracket 52 and the door anti-collision beam 4, reducing damage caused by impact, and further reducing direct damage to passengers and the door 100, thereby improving the protection of passengers.

[0068] In actual design, Figure 2 and Figure 7 As shown, the outer periphery of the bracket energy absorbing cavity 61 , namely the outer peripheral edges of the first collision bracket 51 and the second collision bracket 52 , can be connected by spot welding to achieve a reliable connection between the first collision bracket 51 and the second collision bracket 52 .

[0069] In some embodiments, as Figure 1 As shown, the door anti-collision beam 4 is arranged to extend in the front-to-back direction, which is beneficial to provide additional support for the vehicle door 100 and enables the door anti-collision beam 4 to better absorb collision energy during a side collision, thereby reducing the impact on the vehicle door 100 and the occupants. The front and rear ends of the door anti-collision beam 4 are fixedly connected between the vehicle door inner panel 1 and the vehicle door outer panel 2, wherein the front end of the door anti-collision beam 4 is connected between the vehicle door inner panel 1 and the vehicle door outer panel 2 through a first connecting plate 91, and the rear end of the door anti-collision beam 4 is connected between the vehicle door inner panel 1 and the vehicle door outer panel 2 through a second connecting plate 92. The connection can be made by welding, bolting, etc. to improve the connection firmness of the door anti-collision beam 4 and ensure that the door anti-collision beam 4 can function stably during a collision and will not fall off or shift due to force.

[0070] Furthermore, the middle part of the door anti-collision beam 4 is spaced apart from the door inner panel 1 and the door outer panel 2, that is, the middle part of the door anti-collision beam 4 does not contact the door inner panel 1 and the door outer panel 2, but is spaced apart by a certain distance. As a result, the door anti-collision beam 4 can be deformed to a certain extent when it is hit by a collision, so as to better absorb the collision energy and reduce the impact force on the vehicle.

[0071] In some embodiments, as Figure 1 As shown, the door anti-collision beam 4 is arranged to be inclined downward from the front to the rear along the front-to-rear direction. As a result, the door anti-collision beam 4 can better guide the collision force when a side collision occurs, so as to ensure that the energy can be absorbed to the maximum extent and the damage to the occupants can be reduced during the collision. At the same time, the collision speed can be transmitted to the rear end of the door inner panel 1 faster.

[0072] Furthermore, if Figure 1 As shown, the collision bracket 5 is connected to the rear area above the door anti-collision beam 4, thereby allowing the collision speed to be transmitted to the rear end of the door inner panel 1 more quickly through the collision bracket 5, further realizing efficient transmission of the collision speed.

[0073] The utility model also provides a vehicle.

[0074] A vehicle according to an embodiment of the present invention includes the vehicle door 100 according to any one of the above embodiments.

[0075] By installing the above-mentioned door 100 with high pillar impact performance in the vehicle, the impact force on the door 100 is dispersed and absorbed, thereby reducing the deformation of the door 100 and preventing the door 100 from breaking, thereby reducing damage to the vehicle, improving the safety of the passengers, enhancing the overall safety performance of the vehicle, and reducing the degree of damage to the vehicle in a collision.

[0076] In some embodiments, as Figure 5 As shown, the vehicle also includes a side outer panel 7 and a B-pillar reinforcement panel 8. The B-pillar reinforcement panel 8 is located on the inner side of the side outer panel 7. The B-pillar reinforcement panel 8 is used to enhance the strength and rigidity of the B-pillar. The B-pillar reinforcement panel 8 is installed with an airbag sensor. The airbag sensor is used to detect a collision and trigger the airbag system. The airbag sensor can receive the collision speed transmitted from the B-pillar reinforcement panel 8 and activate the airbag system in time to protect the occupants. The door inner panel 1 is suitable for overlapping the side outer panel 7. This is conducive to maintaining the sealing and stability of the door 100, and is also conducive to providing additional protection during a collision.

[0077] In practice, if Figure 5As shown, the B-pillar reinforcement plate 8 includes a B-pillar inner reinforcement plate 81 and a B-pillar outer reinforcement plate 82. The B-pillar outer reinforcement plate 82 is located on the outside of the B-pillar inner reinforcement plate 81. When a pillar collision occurs, the collision object 93 collides with the collision area 21 of the door outer panel 2, and first contacts the first collision bracket 51. The bracket energy absorption cavity 61 can absorb part of the collision energy. Then the first collision bracket 51 and the second collision bracket 52 transmit the collision speed to the door inner panel 1. The door inner panel 1 transmits the collision speed in turn to the side outer panel 7 and the B-pillar outer reinforcement plate 82 through deformation, and finally to the B-pillar inner reinforcement plate 81. The airbag sensor is installed on the B-pillar inner reinforcement plate 81. At this time, the airbag sensor on the B-pillar inner reinforcement plate 81 receives the collision speed and triggers the airbag system to operate, so that the airbag can be opened quickly and timely to protect the occupants.

[0078] Therefore, by accelerating the transmission of the collision speed through the first collision bracket 51 and the second collision bracket 52, the B-pillar reinforcement plate 8 can quickly receive the collision speed, and then the airbag sensor can quickly receive the collision speed, thereby realizing timely explosion of the airbag and further ensuring the safety of the occupants in the passenger compartment.
