[0021] like Figure 1 and Figure 2 As shown, the vehicle door assembly 100 according to an embodiment of the present invention includes: a door body 1, an armrest 2, a drive member 3, and a buffer energy-absorbing member 4. The door body 1 defines a receiving space 11, and a clearance notch 12 communicating with the receiving space 11 is formed on the side of the door body 1 facing the passenger compartment of the vehicle. The armrest 2 passes through the clearance notch 12 and a portion of the armrest 2 is received in the receiving space 11. The armrest 2 is movable relative to the door body 1. The drive member 3 is received in the receiving space 11 and includes: a drive body 31 and a drive shaft 32. The drive body 31 is disposed on the door body 1, and the drive shaft 32 is connected to both the drive body 31 and the armrest 2.

[0023] The handrail 2 is inserted through the clearance notch 12 and part of the handrail 2 is housed in the housing space 11. As some embodiments of this application, the clearance notch 12 is adapted to the handrail 2 so that the handrail 2 is inserted through the clearance notch 12.

[0024] The handrail 2 is movable relative to the door body 1. As some embodiments of this application, the handrail 2 can rotate or move relative to the door body 1.

[0025] The drive unit 3 is housed in the housing space 11 and includes a drive body 31 and a drive shaft 32. As some embodiments of this application, the drive body 31 and the drive shaft 32 are housed in the housing space 11.

[0026] As some embodiments of this application, the drive component 3 may be constructed as, but is not limited to, a motor, a hydraulic cylinder, a pneumatic cylinder, etc. As some embodiments of this application, when the drive component 3 is constructed as a motor, the drive body 31 is the motor body and the drive shaft 32 is the motor shaft.

[0027] The drive body 31 is disposed on the door body 1. As in some embodiments of this application, it extends along the width direction of the vehicle (i.e., Figure 2 (As shown in the Y direction), the drive body 31 can be located on the side of the outer panel 111 facing the passenger compartment of the vehicle. As some embodiments of this application, the connection method between the drive component 3 and the door body 1 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc.

[0028] The drive shaft 32 is connected to both the drive body 31 and the handrail 2. As some embodiments of this application, along the axial direction of the drive shaft 32, one end of the drive shaft 32 is connected to the drive body 31, and the other end of the drive shaft 32 is connected to the handrail 2. As some embodiments of this application, the connection method between the drive shaft 32 and the handrail 2 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc.

[0029] As some embodiments of this application, the axial direction of the drive shaft 32 is parallel to the width direction of the vehicle described above (i.e., Figure 2 (The Y direction shown is the same).

[0030] The drive body 31 is used to drive the drive shaft 32 along the width direction of the vehicle (i.e., Figure 2 The armrest 2 moves along the width direction of the vehicle (as shown in the Y direction) to drive its movement. As some embodiments of this application, this is done along the width direction of the vehicle (i.e.,...). Figure 2 (As shown in the Y direction), the drive body 31 drives the drive shaft 32 to move, so as to drive the armrest 2 to move closer to or away from the door body 1 via the drive shaft 32.

[0031] The energy-absorbing buffer 4 is housed in the receiving space 11. As some embodiments of this application, the energy-absorbing buffer 4 can be fixedly connected to the side of the armrest 2 facing away from the passenger compartment of the vehicle, or the door body 1 includes components along the width direction of the vehicle (i.e., Figure 2 The outer panel 111 and inner panel 112 are arranged at intervals in the Y direction shown. The buffer energy absorption member 4 can be fixedly connected to the side of the outer panel 111 facing the passenger compartment of the vehicle, or the two ends of the buffer energy absorption member 4 can be fixedly connected to the side of the armrest 2 away from the passenger compartment of the vehicle and the side of the outer panel 111 facing the passenger compartment of the vehicle.

[0032] When a vehicle collision occurs, the buffer energy-absorbing component 4 can be compressed to absorb energy and reduce the damage to the occupants.

[0033] It should be noted that the vehicle door assembly 100 of this application has a handrail 2 passing through the avoidance gap 12 and part of the handrail 2 being housed in the housing space 11. The handrail 2 is movable relative to the door body 1, which facilitates the adjustment of the position of the handrail 2, making it easier to avoid occupants in the event of a vehicle collision, reducing the injury to occupants caused by the collision, and improving the collision safety of the vehicle. Furthermore, by adjusting the position of the handrail 2, the comfort needs of different occupants can be met, thereby improving the comfort of the ride. At the same time, the buffer energy-absorbing member 4 is housed in the housing space 11, and the energy-absorbing member 4 can absorb energy through compression, reducing the impact force between the occupant and the handrail 2, further reducing the injury to occupants caused by the collision, and further improving the collision safety of the vehicle.

[0034] Therefore, by making the armrest 2 movable relative to the door body 1, the position of the armrest 2 can be adjusted by actively avoiding collisions, thereby reducing the injury to the occupants inside the vehicle. Moreover, the energy-absorbing buffer 4 can be used to absorb energy and improve the collision safety of the vehicle. In addition, it can meet the comfort needs of different occupants and improve the comfort of riding.

[0035] In some embodiments of the present invention, such as Figure 2 As shown, the drive shaft 32 is rotatably connected to the handrail 2, along the extending direction of the handrail 2 (i.e., Figure 2(as shown in the X direction), the two drive components 3 are arranged at intervals and are set at both ends of the handrail 2.

[0036] As some embodiments of this application, the number of driving components 3 can be two, and the driving shafts 32 of the two driving components 3 are rotatably connected to both ends of the handrail 2 respectively. As some embodiments of this application, the driving shafts 32 and the handrail 2 are rotatably connected by hinges.

[0037] This configuration allows for multi-point drive via two drive components 3, which improves the stability of the handrail 2 during overall movement. Furthermore, it enables the handrail 2 to rotate, allowing for selective adjustment of the positions at both ends of the handrail 2 to meet the comfort needs of different passengers and further enhance ride comfort.

[0038] In some embodiments of the present invention, such as Figure 2 As shown, the armrest 2 includes: a first armrest portion 21, a second armrest portion 22, and a third armrest portion 23. The second armrest portion 22 connects the first armrest portion 21 and the third armrest portion 23 and is spaced apart from the door body 1. The clearance notch 12 includes a section along the extending direction of the armrest 2 (i.e., Figure 2 The first clearance gap 121 and the second clearance gap 122 (shown in the X direction) are spaced apart. The first handrail part 21 is inserted through the first clearance gap 121 and is housed in the housing space 11. The third handrail part 23 is inserted through the second clearance gap 122 and is housed in the housing space 11.

[0039] The second handrail portion 22 connects the first handrail portion 21 and the third handrail portion 23. As in some embodiments of this application, along the extending direction of the handrail 2 (i.e. Figure 2 (As shown in the X direction), the first handrail portion 21, the second handrail portion 22, and the third handrail portion 23 are arranged in sequence. One end of the second handrail portion 22 is connected to the first handrail portion 21, and the other end of the second handrail portion 22 is connected to the third handrail portion 23. Specifically, the second handrail portion 22, the first handrail portion 21, and the third handrail portion 23 have a U-shaped structure. As some embodiments of this application, the connection method between the second handrail portion 22 and the first handrail portion 21 and the third handrail portion 23 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc. Alternatively, the second handrail portion 22 and the first handrail portion 21 and the third handrail portion 23 can be integrally formed.

[0040] The second armrest 22 is spaced apart from the door body 1. As some embodiments of this application, it extends along the width direction of the vehicle (i.e., Figure 2 (As shown in the Y direction), the second armrest 22 is set parallel or approximately parallel to the door body 1.

[0041] The clearance 12 includes the extension direction along the handrail 2 (i.e. Figure 2As shown in the X direction, the first clearance gap 121 and the second clearance gap 122 are spaced apart. In some embodiments of this application, the first clearance gap 121 is arranged corresponding to the first handrail part 21, and the second clearance gap 122 is arranged corresponding to the third handrail part 23. The distance between the first clearance gap 121 and the second clearance gap 122 is equal to the distance between the first handrail part 21 and the third handrail part 23.

[0042] The first handrail portion 21 is inserted through the first clearance notch 121 and is received in the receiving space 11. The third handrail portion 23 is inserted through the second clearance notch 122 and is received in the receiving space 11. As some embodiments of this application, the first clearance notch 121 is adapted to the first handrail portion 21 so that the first handrail portion 21 is inserted through the first clearance notch 121, and the second clearance notch 122 is adapted to the third handrail portion 23 so that the third handrail portion 23 is inserted through the second clearance notch 122.

[0043] This design facilitates the assembly of the armrest 2 and the door body 1, reducing the assembly difficulty of the armrest 2 and the door body 1. Furthermore, both ends of the armrest 2 can be assembled with the door body 1, which can improve the stability of the armrest 2 when it moves as a whole. Moreover, only two small notches need to be set on the door body 1, which can avoid the problem of affecting the structural strength of the door body 1 by opening too large a notch on the door body 1.

[0044] In some embodiments of the present invention, such as Figure 2 As shown, the two drive components 3 correspond to the first armrest 21 and the third armrest 23, respectively.

[0045] This configuration enables multi-point drive, which improves the stability of the armrest 2 during overall movement. Furthermore, it allows the armrest 2 to rotate, so that the positions of the first armrest 21 and the third armrest 23 can be selectively adjusted via the drive shafts 32 of the two drive components 3, thereby meeting the comfort needs of different passengers and further improving the comfort of riding.

[0046] In some embodiments of the present invention, such as Figure 1 As shown, the buffer energy-absorbing component 4 includes: an elastic component 41, at least one elastic component 41 is disposed between the door body 1 and the armrest 2, and / or, at least one elastic component 41 is disposed between the armrest 2 and the drive body 31.

[0047] In this configuration, at least one elastic element 41 is disposed between the door body 1 and the armrest 2, or at least one elastic element 41 is disposed between the armrest 2 and the drive body 31, or at least one elastic element 41 is disposed between the door body 1 and the armrest 2, and at least one elastic element 41 is disposed between the armrest 2 and the drive body 31.

[0048] At least one elastic element 41 is disposed between the door body 1 and the armrest 2. As some embodiments of this application, one or more elastic elements 41 are disposed between the door body 1 and the armrest 2.

[0049] As some embodiments of this application, the elastic element 41 can be fixedly connected to the door body 1 or the armrest 2.

[0050] As some embodiments of this application, the elastic element 41 may be constructed as a spring, such as, but not limited to, a coil spring.

[0051] This allows the elastic element 41 to absorb the collision energy of the vehicle through compression, thereby buffering and reducing the impact force between the passenger and the handrail 2, thus reducing the injury to the occupants and improving the vehicle's collision safety.

[0052] At least one elastic element 41 is disposed between the handrail 2 and the drive body 31. As some embodiments of this application, one or more elastic elements 41 are disposed between the handrail 2 and the drive body 31.

[0053] As some embodiments of this application, the elastic element 41 may be fixedly connected to the handrail 2 or the drive body 31.

[0054] As some embodiments of this application, the elastic element 41 may be constructed as a spring, such as, but not limited to, a coil spring.

[0055] This arrangement allows the elastic element 41 to have various configurations, and it can absorb the collision energy of the vehicle through the compression deformation of the elastic element 41 to perform buffering and energy absorption, thereby reducing the injury to the occupants of the vehicle and improving the collision safety of the vehicle.

[0056] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the buffer energy-absorbing component 4 includes: a damper 42, at least one damper 42 is disposed between the door body 1 and the armrest 2, and / or, at least one damper 42 is disposed between the armrest 2 and the drive body 31.

[0057] At least one damper 42 is disposed between the door body 1 and the armrest 2, or at least one damper 42 is disposed between the armrest 2 and the drive body 31, or at least one damper 42 is disposed between the door body 1 and the armrest 2, and at least one damper 42 is disposed between the armrest 2 and the drive body 31.

[0058] At least one damper 42 is disposed between the door body 1 and the armrest 2. As some embodiments of this application, one or more dampers 42 are disposed between the door body 1 and the armrest 2.

[0059] As some embodiments of this application, the damper 42 can be fixedly connected to the door body 1 or the armrest 2.

[0060] As some embodiments of this application, the damper 42 may be constructed as, but is not limited to, a hydraulic damper 42, a viscoelastic damper 42 (e.g., rubber, silicone), etc.

[0061] This allows the damper 42 to absorb the collision energy of the vehicle, thereby buffering the impact and reducing the force between the passenger and the handrail 2, thus reducing the injury to the occupants and improving the vehicle's collision safety.

[0062] At least one damper 42 is disposed between the handrail 2 and the drive body 31. As some embodiments of this application, one or more dampers 42 are disposed between the handrail 2 and the drive body 31.

[0063] As some embodiments of this application, the damper 42 may be fixedly connected to the handrail 2 or the drive body 31.

[0064] As some embodiments of this application, the damper 42 may be constructed as, but is not limited to, a hydraulic damper 42, a viscoelastic damper 42 (e.g., rubber, silicone), etc.

[0065] This configuration allows the damper 42 to be arranged in various ways, and the damper 42 can absorb and buffer energy, thereby reducing the injury to the occupants of the vehicle during a collision and improving the vehicle's collision safety.

[0066] In some embodiments of the present invention, such as Figure 2 As shown, the buffer energy-absorbing component 4 includes: an elastic element 41 and a damper 42. At least one damper 42 is disposed between the handrail 2 and the drive body 31. The drive shaft 32 passes through the damper 42 between the handrail 2 and the drive body 31. At least one elastic element 41 is disposed between the handrail 2 and the drive body 31 and sleeved on the damper 42 located between the handrail 2 and the drive body 31.

[0067] In some embodiments of this application, one or more dampers 42 are disposed between the handrail 2 and the drive body 31, the drive shaft 32 passes through the damper 42 between the handrail 2 and the drive body 31, and one or more elastic elements 41 are disposed between the handrail 2 and the drive body 31 and sleeved on the damper 42 located between the handrail 2 and the drive body 31.

[0068] As some embodiments of this application, the damper 42 is sleeved on the drive shaft 32, and the elastic element 41 is sleeved on the damper 42. In other words, the elastic element 41, the damper 42, and the drive shaft 32 are sleeved in sequence.

[0069] As some embodiments of this application, the number of dampers 42 and elastic elements 41 may be the same or different.

[0070] This configuration allows the elastic element 41 and damper 42 to jointly absorb the collision energy of the vehicle, thereby buffering and reducing the injury to the occupants and improving the vehicle's collision safety. Furthermore, both the damper 42 and the elastic element 41 can be arranged in various ways, facilitating assembly. By placing at least one damper 42 between the armrest 2 and the drive body 31, with the drive shaft 32 passing through the damper 42 between the armrest 2 and the drive body 31, and at least one elastic element 41 placed between the armrest 2 and the drive body 31 and fitted onto the damper 42 located between the armrest 2 and the drive body 31, the drive shaft 32 can reliably drive the armrest 2 to move closer to or away from the door body 1. This configuration also shortens the length of the damper 42 and the elastic element 41 while meeting practical needs, saving costs.

[0071] In some embodiments of the present invention, the buffer energy-absorbing element 4 includes: an elastic element 41, wherein there are multiple elastic elements 41, and the multiple elastic elements 41 extend along the extension direction of the handrail 2 (i.e., Figure 2 As shown in the X direction, the elastic elements 41 are arranged in some embodiments of this application. The number of elastic elements 41 can be, but is not limited to, three, four, five, etc. The number of elastic elements 41 can be adjusted according to actual needs. Furthermore, the multiple elastic elements 41 are arranged along the extension direction of the handrail 2 (i.e., Figure 2 Arranged in the X direction as shown.

[0072] This design creates multiple energy-absorbing points inside the vehicle door assembly 100 when a collision occurs, and reduces the risk of the armrest 2 being directly reversed by the impact force. This significantly improves the buffering and energy-absorbing effect, further enhancing the vehicle's collision safety.

[0073] In some embodiments of the present invention, such as Figure 2 As shown, the buffer energy-absorbing component 4 includes: a damper 42, and there are multiple dampers 42, which extend along the extension direction of the handrail 2 (i.e., Figure 2 As shown in the X direction, the dampers 42 are arranged in various ways. In some embodiments of this application, the number of dampers 42 can be, but is not limited to, three, four, five, etc. The number of dampers 42 can be adjusted according to actual needs. Furthermore, multiple dampers 42 are arranged along the extending direction of the handrail 2 (i.e.,...). Figure 2 Arranged in the X direction as shown.

[0074] This design creates multiple energy-absorbing points inside the vehicle door assembly 100 when a collision occurs, and reduces the risk of the armrest 2 being directly reversed by the impact force. This significantly improves the buffering and energy-absorbing effect, further enhancing the vehicle's collision safety.

[0075] In some embodiments of the present invention, the vehicle door assembly 100 further includes a controller, which is communicatively connected to the drive unit 3 and configured to control the drive unit 3 to drive the armrest 2 to move into the receiving space 11 when the vehicle is involved in a collision.

[0076] As some embodiments of this application, the controller and the driver 3 can be connected by a wire, or the controller and the driver 3 can be connected wirelessly.

[0077] Understandably, the controller can communicate with the vehicle's occupant detection system, and the acceleration sensor can communicate with the controller. The occupant detection system may include a gravity sensor built into the seat. The gravity sensor can determine whether there is an occupant in the seat, and the acceleration sensor is used to detect whether a collision has occurred (for example, if the vehicle suddenly decelerates and the deceleration exceeds the maximum braking capacity, a collision can be detected). If the controller receives information about a vehicle collision and determines that there is a passenger in the seat, the controller controls the corresponding drive component 3 to drive the corresponding armrest 2 to move rapidly into the receiving space 11, so that the armrest 2 is away from the occupant, thereby protecting the occupant's safety. At the same time, if the occupant hits the armrest 2, the buffer energy-absorbing component 4 can buffer and absorb energy, further protecting the occupant's safety.

[0078] In addition, the occupant detection system can also move at least one end of the armrest 2 into the reception space 11 based on the occupant's body shape, weight, and seat position information, thereby improving passenger comfort.

[0079] According to an embodiment of the present invention, the vehicle includes the door assembly 100 of the vehicle described above. By making the handrail 2 movable relative to the door body 1, the position of the handrail 2 can be adjusted by actively avoiding collisions, thereby reducing the injury to the occupants inside the vehicle. Moreover, the energy-absorbing buffer 4 can be used to absorb energy and improve the collision safety of the vehicle. In addition, it can meet the comfort needs of different occupants and improve the ride comfort.
