The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0025] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0026] See also Figure 1 and Figure 2 The present embodiment provides a vehicle 300, including a vehicle body 301 and a door assembly 200. The door assembly 200 is disposed on the vehicle body 301. The door assembly 200 can be disposed on the front side or the rear side of the vehicle 300.

[0027] See also Figure 3 and Figure 4 The vehicle door assembly 200 includes a vehicle door 201 and an anti-collision beam assembly 100. The anti-collision beam assembly 100 is connected to the vehicle door 201. The anti-collision beam assembly 100 is used to improve the anti-collision performance of the vehicle door assembly 200. The vehicle door 201 includes a vehicle door inner panel 2011 and a vehicle door outer panel 2012. The vehicle door inner panel 2011 and the vehicle door outer panel 2012 are spaced apart along the width direction of the vehicle 300. The anti-collision beam assembly 100 is located between the vehicle door inner panel 2011 and the vehicle door outer panel 2012.

[0028] The anti-collision beam assembly 100 includes an anti-collision beam body 10 and a bracket 20. The bracket 20 includes a force-bearing member 21 and two connecting members 22. The force-bearing member 21 is configured to be connected to the anti-collision beam body 10 through the two connecting members 22, and the distance between the two connecting members 22 is adjustable.

[0029] According to the anti-collision beam assembly 100 of the present embodiment, the distance between the two connecting parts 22 can be adjusted so that it can be adapted to anti-collision beam bodies 10 with different sizes, thereby greatly improving the versatility of the anti-collision beam assembly 100 and reducing the design cost of the anti-collision beam assembly 100 of vehicles 300 of different models. During the assembly of the whole vehicle, the assembly cost of the vehicle 300 can be reduced. During the development of the vehicle 300, different anti-collision beam bodies 10 can be quickly replaced according to actual needs to efficiently obtain more suitable specifications of the anti-collision beam assembly 100, thereby reducing the development cycle of the vehicle 300 and improving development efficiency.

[0030] In this embodiment, the first direction M1 is substantially parallel to the thickness direction of the anti-collision beam assembly 100, the second direction M2 is substantially parallel to the width direction of the anti-collision beam assembly 100, and the third direction M3 is substantially parallel to the length direction of the anti-collision beam assembly 100. After the anti-collision beam assembly 100 is installed on the vehicle 300, the first direction M1 is substantially parallel to the width direction of the vehicle 300, and the second direction M2 is substantially parallel to the height direction of the vehicle 300.

[0031] In some embodiments, see Figure 2 The anti-collision beam body 10 extends from the front end of the vehicle 300 toward the rear end of the vehicle 300, and the end of the anti-collision beam body 10 close to the rear end of the vehicle 300 is inclined downward. The bracket 20 is connected to the end of the anti-collision beam body 10 close to the rear end of the vehicle 300. Both ends of the anti-collision beam body 10 in the length direction can be indirectly connected to the door inner panel 2011 by welding or other structures.

[0032] In some embodiments, the vehicle 300 further includes a sensor assembly (not shown in the figure) and a safety device (not shown in the figure). The safety device can be specifically set as an airbag installed in the vehicle 300. The safety device is electrically connected to the sensor assembly, and the safety device is configured to start when the sensor assembly detects that the collision acceleration reaches a preset value. In this way, after the door 201 of the vehicle 300 is hit, the damaged part of the door 201 approaches and collides with the force-bearing member 21 of the bracket 20, and the sensor assembly can detect the change of the collision acceleration of the door 201, and send a control signal to the controller after the collision acceleration reaches the preset value. After receiving the control signal, the controller controls the safety device to start. Since the anti-collision beam body 10 is additionally provided with a bracket 20, compared with the anti-collision beam of the known technology, the anti-collision beam of this embodiment can achieve the collision of the door outer panel 2012 in a shorter time. After the collision occurs, the sensor assembly can detect the change of the collision acceleration more quickly, thereby improving the response speed of the safety device and improving the safety of the vehicle 300.

[0033] In some embodiments, see Figure 4 , the anti-collision beam body 10 is fixedly connected to the door inner panel 2011, and the force-bearing member 21 is located between the door inner panel 2011 and the door outer panel 2012, so that the force-bearing member 21 can collide with the door outer panel 2012 earlier than the anti-collision beam body 10. In other embodiments, the force-bearing member 21 can be fixedly connected to the door inner panel 2011, so that the bracket 20 plays the role of installing the anti-collision beam body 10 on the door inner panel 2011.

[0034] In some embodiments, see Figure 4 The anti-collision beam body 10 has a first surface P1 close to the force-bearing member 21 along the first direction M1, the force-bearing member 21 has a second surface P2 away from the anti-collision beam body 10 along the first direction M1, and the force-bearing member 21 also has a bottom surface P4 arranged opposite to the second surface P2. The bottom surface P4 is spaced apart from the first surface P1, or the bottom surface P4 is attached to the first surface P1. Both connecting members 22 are adjustably connected to the anti-collision beam body 10 to adjust the distance between the first surface P1 and the second surface P2. In this way, when installing the anti-collision beam assembly 100, the distance between the first surface P1 and the second surface P2 can be adjusted according to the required collision detection time of the vehicle door 201 to meet the requirements of different safety device activation times.

[0035] In some embodiments, see Figure 4The anti-collision beam body 10 includes a top wall 11, two side walls 12, two bottom walls 13 and a recessed portion 14. The two side walls 12 are distributed along the second direction M2, the top wall 11 is connected between the two side walls 12, the recessed portion 14 is arranged in the middle of the top wall 11, and the two bottom walls 13 are respectively connected to the two side walls 12, and the two bottom walls 13 extend opposite to each other along the second direction M2. Among them, the two bottom walls 13 are respectively used for welding connection with the door inner panel 2011. The two side walls 12 are respectively connected to the two connecting members 22. The top wall 11 defines a first surface P1.

[0036] In some embodiments, see Figure 4 The recessed portion 14 includes a bottom edge 142 and two side edges 141. The bottom edge 142 is located between the bottom wall 13 and the top wall 11 along the third direction M3. The two ends of the side edge 141 are respectively connected between the bottom edge 142 and the top wall 11, and form a groove C.

[0037] In some embodiments, the anti-collision beam assembly 100 further includes a fastener, and the connecting member 22 is provided with a waist-shaped hole extending along the first direction M1, and the waist-shaped hole is used for the fastener to penetrate to adjustably lock the connecting member 22 to the anti-collision beam body 10. In this way, by generating relative movement between the fastener and the connecting member 22, the connecting member 22 can be moved to different positions relative to the anti-collision beam body 10 along the first direction M1, thereby adjusting the spacing between the first surface P1 and the second surface P2. When the anti-collision beam assembly 100 is actually installed, the spacing between the first surface P1 and the second surface P2 can be adjusted according to the spacing requirement between the second surface P2 and the door outer panel 2012, and then the connecting member 22 can be fixed to the anti-collision beam body 10 by the fastener. In other embodiments, the waist-shaped hole can be provided in the anti-collision beam body 10.

[0038] In some embodiments, when the anti-collision beam assembly 100 is actually installed, the connection position of the connecting member 22 and the anti-collision beam body 10 can be determined based on the spacing requirement between the second surface P2 and the vehicle door outer panel 2012, and then the connecting member 22 and the anti-collision beam body 10 are welded, so as to improve the structural stability of the anti-collision beam assembly 100. When the length of the connecting member 22 along the first direction M1 is long, the portion of the connecting member 22 close to the vehicle door inner panel 2011 can be cut to meet the installation requirements.

[0039] In some embodiments, the force-bearing member 21 is located on one side of the anti-collision beam body 10 along the first direction M1, and one end of the two connecting members 22 along the first direction M1 is respectively connected to the two sides of the anti-collision beam body 10 along the second direction M2, the second direction M2 intersects with the first direction M1, and the other ends of the two connecting members 22 along the first direction M1 are respectively connected to the two ends of the force-bearing member 21 along the second direction M2, and one of the connecting members 22 is adjustably connected to the force-bearing member 21 to adjust the spacing of the two connecting members 22 along the second direction M2. In this way, by adjusting the spacing between one connecting member 22 and the force-bearing member 21 along the second direction M2, the spacing adjustment of the two connecting members 22 along the second direction M2 can be achieved. When assembling the anti-collision beam assembly 100, first determine the size of the anti-collision beam body 10 along the second direction M2, then control the spacing of the two connecting members 22 along the second direction M2, and respectively connect the two connecting members 22 to the two sides of the anti-collision beam body 10 along the second direction M2. This adjustment method has a stable structure and is easy to adjust.

[0040] In other embodiments, the two connecting members 22 may also be connected to other positions of the anti-collision beam body 10 . For example, the two connecting members 22 may be installed on one side of the anti-collision beam body 10 close to the force-bearing member 21 along the first direction M1 .

[0041] In some embodiments, see Figure 4 , the anti-collision beam assembly 100 also includes two adjusting members 23. One end of the force-bearing member 21 along the second direction M2 is adjustably connected to a connecting member 22 through an adjusting member 23, and the other end of the force-bearing member 21 along the second direction M2 is adjustably connected to another connecting member 22 through another adjusting member 23. In this way, the position adjustment range of the force-bearing member 21 can be expanded, so that the projection of the force-bearing member 21 along the third direction M3 on the anti-collision beam body 10 is located in the middle position of the anti-collision beam body 10 along the second direction M2, thereby ensuring the buffering effect of the force-bearing member 21 during the collision process.

[0042] In some embodiments, see Figure 4 and Figure 5 , the adjusting member 23 is passed through the connecting member 22. The bracket 20 further includes a locking member 24, which is connected to one end of the adjusting member 23 away from the connecting member 22, and is used to fix the connecting member 22 to the adjusting member 23. In this way, a stable connection between the connecting member 22 and the adjusting member 23 is achieved, ensuring the stability of the connection structure between the bracket 20 and the anti-collision beam body 10. Among them, the locking member 24 can be set as a locking nut.

[0043] In some embodiments, see Figure 4 and Figure 5The adjusting member 23 includes an adjusting rod 231 and a limiting portion 232. The adjusting rod 231 is adjustably connected to the force bearing member 21, the limiting portion 232 is convexly arranged on the outer peripheral surface of the adjusting rod 231, the connecting member 22 is located on the side of the limiting portion 232 away from the force bearing member 21, and the locking member 24 fixes the connecting member 22 to the limiting portion 232. In this way, the connection stability between the adjusting rod 231 and the connecting member 22 can be improved to reduce the possibility of the bracket 20 loosening relative to the anti-collision beam body 10. The limiting portion 232 can be constructed as an annular flange connected to the outer peripheral surface of the adjusting rod 231.

[0044] In some embodiments, see Figure 4 and Figure 5 , threaded holes K1 are provided on two side surfaces P3 of the force-bearing member 21 that are arranged opposite to each other along the second direction M2, the adjusting member 23 is passed through the threaded hole K1 and is threadedly connected to the force-bearing member 21, and the adjusting member 23 is configured to be screwed into or out of the threaded hole K1 to adjust the distance between the connecting member 22 and the force-bearing member 21.

[0045] In some embodiments, the connecting member 22 defines a through hole K2 , and the adjusting member 23 passes through the through hole K2 and is threadedly connected to the threaded hole K1 .

[0046] In some embodiments, along the third direction M3, a plurality of threaded holes K1 and a plurality of through holes K2 are provided respectively, and the number of the adjusting members 23, the number of the threaded holes K1 and the number of the through holes K2 are the same, so that the installation stability of the force-bearing member 21 can be improved.

[0047] In other implementations, a strip hole may be opened in the adjusting member 23, and the adjusting member 23 may pass through different positions of the strip hole, so that the connecting member 22 is fixedly connected to the force-bearing member 21 at different positions.

[0048] In another embodiment, the force-bearing member 21 can also be constructed into two parts along the second direction M2. The two parts are adjustably connected by a screw to adjust the length of the force-bearing member 21. The two parts are respectively connected to two connecting members 22. In this way, the distance between the two connecting members 22 can also be adjusted to meet the installation requirements of different anti-collision beam bodies 10.

[0049] In some embodiments, see Figure 4 , one end of the adjusting member 23 inserted into the threaded hole is inclined in a direction close to the anti-collision beam body 10. In this way, when the force-bearing member 21 is impacted, the force-bearing member 21 is easier to move toward the anti-collision beam body 10, thereby improving the buffering performance.

[0050] In some embodiments, the length direction of the force-bearing member 21 extends along the length direction of the anti-collision beam body 10, the thickness direction of the force-bearing member 21 is parallel to the first direction M1, and the width direction of the force-bearing member 21 is parallel to the second direction M2. Among them, the length of the force-bearing member 21 is greater than the width of the force-bearing member 21, the width of the force-bearing member 21 is greater than the thickness of the force-bearing member 21, and the thickness of the force-bearing member 21 is greater than the thickness of the connecting member 22, and the thickness of the force-bearing member 21 is greater than the thickness of the top wall 11 of the anti-collision beam body 10. There is a gap between the top wall 11 and the door inner panel 2011, and the ratio between the thickness of the force-bearing member 21 (i.e., the distance between the second surface P2 and the bottom surface P4) and the gap is not less than 0.5. For example, the ratio between the thickness and the height of the force-bearing member 21 can be set between 0.5 and 2. For example, the ratio can be set to any one of 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, and 2. In this way, the impact resistance of the force-bearing member 21 can be significantly improved, thereby improving the anti-collision effect. In addition, the thickness of the force-bearing member 21 is relatively large, and a relatively high strength can be maintained after the threaded hole K1 is opened in the force-bearing member 21.

[0051] In some embodiments, the material of the stress-bearing member 21 is aluminum or a composite material, and the material of the connecting member 22 is steel. In this way, the connection reliability of the connecting member 22 connecting the stress-bearing member 21 and the anti-collision beam body 10 can be ensured.

[0052] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
