[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is for reference. Figures 1-5 The adjustment component 100 according to an embodiment of the present invention is described.

[0033] like Figures 1-5 As shown, the adjustment assembly 100 according to an embodiment of the present invention includes: a first mounting base 10, a second mounting base 20, and a rotating swing arm 30.

[0034] The first mounting base 10 and the second mounting base 20 are connected. As some optional embodiments of this application, the first mounting base 10 and the second mounting base 20 can be connected by bolts. The first mounting base 10 can rotate relative to the second mounting base 20. Specifically, the first mounting base 10 can rotate relative to the second mounting base 20 about a first axis. Furthermore, the first mounting base 10 is suitable for connection with the door body. As some optional embodiments of this application, the first mounting base 10 can be fixedly connected to the door body.

[0035] The rotating arm 30 is connected to the second mounting base 20. The rotating arm 30 is rotatable relative to the second mounting base 20. Specifically, the rotating arm 30 can rotate relative to the second mounting base 20 about a second axis. The first axis and the second axis are perpendicular to each other. As some optional embodiments of this application, the first axis can be perpendicular to the second mounting base 20. Figure 1 The X-direction shown is parallel, and the second axis can be Figure 1 The Z-direction shown is parallel.

[0036] As some optional embodiments of this application, one end of the rotating swing arm 30 can be connected to the second mounting base 20, and the other end of the rotating swing arm 30 can be connected to the vehicle body. The door can be a vehicle door.

[0037] During installation, the rotating arm 30 can be connected to the second mounting base 20, and then connected to the vehicle body. The first mounting base 10 and the second mounting base 20 can also be connected. Next, the first mounting base 10 can be installed with the vehicle door. Then, the door and the first mounting base 10 can be pushed to rotate relative to the second mounting base 20 around a first axis, allowing the door to rotate relative to the vehicle body to adjust the gap between the door and the body. This allows for gap adjustment between the door and the body without disassembling the adjustment assembly 100, reducing the difficulty of adjusting the gap between the door and the body. Furthermore, the adjustment tolerance is large, satisfying the needs of gap adjustment between the door and the body. Since the rotating arm 30 and the second mounting base 20 are rotatably connected, the opening and closing function of the door is not affected, improving the reliability of the adjustment assembly 100.

[0038] Therefore, by cooperating with the first mounting seat 10 and the second mounting seat 20, after the door body is installed on the first mounting seat 10, the door body and the first mounting seat 10 can be controlled to rotate together around the first axis relative to the second mounting seat 20. Thus, the gap between the door body and the vehicle body can be adjusted without disassembling the adjustment assembly 100, reducing the difficulty of adjusting the gap between the door body and the vehicle body.

[0039] As some optional embodiments of this application, Figure 1 The X direction shown can be the length direction of the vehicle. Figure 1 The Z direction shown can be the height direction of the vehicle, and this application can realize the Y direction (i.e. the width direction of the vehicle) adjustment of the door.

[0040] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 5 As shown, the first mounting base 10 may include a first mounting portion 11, which may define a first mounting space 13. The second mounting base 20 may include a first sub-body 21, at least a portion of which may be disposed in the first mounting space 13. Furthermore, the first sub-body 21 may be pivotally connected to the first mounting portion 11, meaning that the first sub-body 21 and the first mounting portion 11 may rotate relative to each other.

[0041] As some optional embodiments of this application, such as Figure 1 and Figure 2 As shown, the first mounting portion 11 may include two opposing first mounting plates 12, which together define a first mounting space 13. At least a portion of the first sub-body 21 may be disposed between the two first mounting plates 12, and the first sub-body 21 may be pivotally connected to the two first mounting plates 12. This arrangement enables the first mounting base 10 and the second mounting base 20 to be pivotally connected together, thereby allowing the first mounting base 10 to rotate relative to the second mounting base 20 about a first axis, and also makes the structure of the first mounting base 10 and the second mounting base 20 more reasonable.

[0042] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 5 As shown, the first mounting part 11 may have a first connecting hole 121, which is a through hole, and the first sub-body 21 may have a second connecting hole 211 corresponding to the first connecting hole 121, which is also a through hole. The first connecting hole 121 and the second connecting hole 211 can be connected along... Figure 1Corresponding to the X direction shown, the first connector 40 can be inserted through the first connecting hole 121 and the second connecting hole 211 to pivotally connect the first mounting base 10 and the second mounting base 20 together, and the axis of the first connector 40 can be the first axis.

[0043] As some optional embodiments of this application, the first connector 40 can be a bolt. By providing a first connecting hole 121 on the first mounting portion 11 and a second connecting hole 211 corresponding to the first connecting hole 121 on the first sub-body 21, the first mounting seat 10 and the second mounting seat 20 can be pivotally connected together by the first connector 40, thereby enabling the first mounting seat 10 to rotate relative to the second mounting seat 20 about the axis of the first connector 40, and enabling the door body to rotate relative to the vehicle body to adjust the gap surface difference between the door body and the vehicle body.

[0044] As some optional embodiments of this application, such as Figure 1 and Figure 2 As shown, the first mounting portion 11 may include two opposing first mounting plates 12, each of which may have a second connecting hole 211. This arrangement ensures a secure connection between the first mounting base 10 and the second mounting base 20, and reduces the assembly difficulty of the first mounting base 10 and the second mounting base 20.

[0045] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, the first mounting base 10 may further include a second mounting portion 14, which may define a second mounting space 16. The second mounting base 20 may further include a second sub-body 22, at least a portion of which may be disposed in the second mounting space 16. The second sub-body 22 may be movably connected to the second mounting portion 14, that is, the second sub-body 22 and the second mounting portion 14 may be displaced relative to each other.

[0046] As some optional embodiments of this application, such as Figure 1 and Figure 2As shown, the second mounting portion 14 may include two opposing second mounting plates 15, which together define a second mounting space 16. At least a portion of the second sub-body 22 may be disposed between the two second mounting plates 15, and the second sub-body 22 may be pivotally connected to the two second mounting plates 15. This arrangement makes the structure of the first mounting base 10 and the second mounting base 20 more reasonable, improves the connection between the first mounting base 10 and the second mounting base 20, and when the first mounting base 10 rotates relative to the second mounting base 20 about the first axis, since the second sub-body 22 can be movably connected to the second mounting portion 14, the second sub-body 22 and the second mounting portion 14 can be displaced relative to each other to avoid affecting the rotation of the first mounting base 10.

[0047] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, the second mounting part 14 may have a third connecting hole 151, which is a through hole, and the second sub-body 22 may have a fourth connecting hole 221 corresponding to the third connecting hole 151, which is also a through hole. The third connecting hole 151 and the fourth connecting hole 221 can be connected along... Figure 1 Corresponding to the X direction shown, the second connector 41 can be inserted into the third connecting hole 151 and the fourth connecting hole 221, and the diameter of the fourth connecting hole 221 is larger than the outer diameter of the second connector 41.

[0048] As some optional embodiments of this application, the second connector 41 can be a bolt. By providing a third connecting hole 151 on the second mounting part 14 and a fourth connecting hole 221 corresponding to the third connecting hole 151 on the second sub-body 22, and making the diameter of the fourth connecting hole 221 larger than the outer diameter of the second connector 41, the second sub-body 22 and the second mounting part 14 can be displaced relative to each other when the second connector 41 is not tightened. It is understood that when the second mounting part 14 moves relative to the second sub-body 22, it can drive the second connector 41 to move. Since the diameter of the fourth connecting hole 221 is larger than the outer diameter of the second connector 41, the fourth connecting hole 221 will not restrict the movement of the second connector 41, thereby avoiding affecting the rotation of the first mounting seat 10 and reliably adjusting the gap surface difference between the door body and the body.

[0049] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, a first bushing 42 may be provided between the first mounting part 11 and the first sub-body 21. The first bushing 42 may have a protruding structure protruding toward the first mounting part 11.

[0050] Alternatively, a second bushing 43 may be provided between the second mounting part 14 and the second sub-body 22, and the second bushing 43 may have a protruding structure protruding toward the second mounting part 14.

[0051] Alternatively, a first bushing 42 may be provided between the first mounting portion 11 and the first sub-body 21, and the first bushing 42 may have a protruding structure protruding toward the first mounting portion 11. Furthermore, a second bushing 43 may be provided between the second mounting portion 14 and the second sub-body 22, and the second bushing 43 may have a protruding structure protruding toward the second mounting portion 14.

[0052] By providing the first bushing 42, when the first connector 40 is tightened, the protruding structure of the first bushing 42 can deform the first mounting portion 11, thereby reducing the probability of the first mounting seat 10 and the second mounting seat 20 becoming loose. By providing the second bushing 43, when the second connector 41 is tightened, the protruding structure of the second bushing 43 can deform the second mounting portion 14, thereby reducing the probability of the first mounting seat 10 and the second mounting seat 20 becoming loose.

[0053] As some optional embodiments of this application, such as Figure 1 and Figure 2 As shown, the first mounting portion 11 may include two opposing first mounting plates 12, one of which may have a first bushing 42 disposed between it and the first sub-body 21. Alternatively, each first mounting plate 12 may have a first bushing 42 disposed between it and the first sub-body 21, i.e., the number of first bushings 42 may be set to two. One first bushing 42 may be located between one of the first mounting plates 12 and the first sub-body 21, and this first bushing 42 has a protruding structure protruding in a direction away from the first mounting plate 12. The other first bushing 42 may be located between the other first mounting plate 12 and the first sub-body 21, and this first bushing 42 also has a protruding structure protruding in a direction away from the first mounting plate 12.

[0054] As some optional embodiments of this application, such as Figure 1 and Figure 2As shown, the second mounting portion 14 may include two opposing second mounting plates 15. A second bushing 43 may be provided between one of the second mounting plates 15 and the second sub-body 22. Alternatively, a second bushing 43 may be provided between each of the second mounting plates 15 and the second sub-body 22, meaning the number of second bushings 43 can be two. One second bushing 43 may be located between one of the second mounting plates 15 and the second sub-body 22, and this second bushing 43 has a protruding structure extending away from the second mounting plate 15. The other second bushing 43 may be located between the other second mounting plate 15 and the second sub-body 22, and this second bushing 43 also has a protruding structure extending away from the second mounting plate 15.

[0055] In some embodiments of the present invention, such as Figures 1-3 As shown, the second mounting base 20 may further include a third sub-body 23, which can be connected between the first sub-body 21 and the second sub-body 22. The third sub-body 23 may have a first end and a second end, with the first end of the third sub-body 23 connected to the first sub-body 21 and the second end of the third sub-body 23 connected to the second sub-body 22. This configuration allows the first sub-body 21 and the second sub-body 22 to be connected together via the third sub-body 23, so that the first sub-body 21, the second sub-body 22, and the third sub-body 23 form a single unit.

[0056] As some optional embodiments of this application, the first sub-body 21, the second sub-body 22 and the third sub-body 23 are a single piece.

[0057] The following details the usage of the adjustment component 100. In use, the rotating arm 30 is first connected to the second mounting base 20, and then to the vehicle body. The first mounting base 10 and the second mounting base 20 are also connected. At this time, the first connecting piece 40 is tightened (i.e., the first connecting piece 40 is interference-fitted with the first sub-body 21), while the second connecting piece 41 is not tightened (i.e., the second connecting piece 41 is clearance-fitted with the second sub-body 22). Then, the first mounting base 10 can be installed with the vehicle door. The door and the first mounting base 10 can then be pushed to rotate relative to the second mounting base 20 around the first axis. Because the second connecting piece 41 is not tightened, and the diameter of the fourth connecting hole 221 is larger than the outer diameter of the second connecting piece 41, the fourth connecting hole 221 will not restrict the movement of the second connecting piece 41 when the door and the first mounting base 10 rotate relative to the second mounting base 20 around the first axis. This avoids affecting the rotation of the first mounting base 10 and reliably adjusts the gap between the door and the vehicle body. After adjusting the gap between the door and the vehicle body, the second connector 41 can be tightened. Since a second bushing 43 is provided between the second mounting part 14 and the second sub-body 22, and the second bushing 43 has a protruding structure protruding towards the second mounting part 14, when the second connector 41 is tightened, the protruding structure of the first bushing 42 can deform the first mounting part 11, thereby reducing the probability of the first mounting seat 10 and the second mounting seat 20 becoming loose.

[0058] As some optional embodiments of this application, such as Figure 1 and Figure 2 As shown, the other end of the first connector 40 can be engaged with the nut 46, and the other end of the second connector 41 can be engaged with the nut 46.

[0059] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, a portion of the structure of the rotating arm 30 can be disposed between the first sub-body 21 and the second sub-body 22. Furthermore, the rotating arm 30 can be connected to the second mounting base 20. The rotating arm 30 can rotate relative to the second mounting base 20 around the second axis. By disposing a portion of the structure of the rotating arm 30 between the first sub-body 21 and the second sub-body 22, the placement of the rotating arm 30 can be made reasonable, thereby facilitating the connection between the rotating arm 30 and the second mounting base 20 and reducing the assembly difficulty between the rotating arm 30 and the second mounting base 20.

[0060] In some embodiments of the present invention, such as Figure 1 and Figure 4As shown, the rotating arm 30 may have a first mounting hole 31, which can penetrate the rotating arm 30 along the second axis. The first sub-body 21 and the second sub-body 22 may both have a second mounting hole 24, which may be a through hole and correspond to the first mounting hole 31. The pin 34 may be disposed in the first mounting hole 31 and the second mounting hole 24, and the axis of the pin 34 may be the second axis. The pin 34 may be fixedly connected to the second mounting base 20.

[0061] As some optional embodiments of this application, such as Figure 4 As shown, the end of the pin 34 near the second sub-body 22 may have a flange 32, the diameter of which may be larger than the diameter of the second mounting hole 24 provided on the second sub-body 22. The end of the pin 34 near the first sub-body 21 may be located inside the second mounting hole 24 provided on the first sub-body 21, that is, the end of the pin 34 near the first sub-body 21 does not protrude from the second mounting hole 24 provided on the first sub-body 21. The screw 47 may extend from the end of the pin 34 near the first sub-body 21 into the pin 34 to fix the pin 34. The rotating arm 30 may be sleeved on the pin 34. When opening and closing the car door, the rotating arm 30 may rotate relative to the pin 34 around the second axis to realize the opening and closing of the car door.

[0062] As some optional embodiments of this application, the diameter of the middle section of the pin 34 can be greater than the diameter of the end of the pin 34 near the first sub-body 21, so that the pin 34 can have a boss structure 33, which can abut against the first sub-body 21.

[0063] As some optional embodiments of this application, the pin 34 may have a mating hole for the screw 47 to extend into. As some optional embodiments of this application, the screw 47 may be of type M8*40. As some optional embodiments of this application, a washer 44 may be provided between the pin 34 and the first sub-body 21, and a washer 44 may be provided between the pin 34 and the second sub-body 22. As some optional embodiments of this application, a third bushing 45 may be provided between the pin 34 and the rotating rocker arm 30.

[0064] As some optional embodiments of this application, the gasket 44, the third bushing 45, the second bushing 43, and the first bushing 42 can all be made of steel. The nut 46 can be a press-fit nut 46.

[0065] According to an embodiment of the present invention, a door assembly includes a door body and an adjustment assembly 100. The adjustment assembly 100 is the same as described above. A first mounting seat 10 is connected to the door body, and a rotating swing arm 30 is connected to the vehicle body. By cooperating with the first mounting seat 10 and the second mounting seat 20, after the door body is mounted on the first mounting seat 10, the door body and the first mounting seat 10 can be controlled to rotate together around a first axis relative to the second mounting seat 20. Therefore, the gap between the door body and the vehicle body can be adjusted without disassembling the adjustment assembly 100, reducing the difficulty of adjusting the gap between the door body and the vehicle body.

[0066] The vehicle according to an embodiment of the present invention includes the door assembly of the above embodiment. By cooperating with the first mounting seat 10 and the second mounting seat 20, after the door body is installed on the first mounting seat 10, the door body and the first mounting seat 10 can be controlled to rotate together around the first axis relative to the second mounting seat 20. Thus, the gap between the door body and the vehicle body can be adjusted without disassembling the adjustment assembly 100, reducing the difficulty of adjusting the gap between the door body and the vehicle body.
