DETAILED DESCRIPTION

[0042] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0043] An adjustment mechanism proposed in an embodiment of the present invention will be described below with reference to the accompanying drawings;

[0044] like Figure 1 、 Figure 2 、 Figure 5 As shown, according to some embodiments of the present invention, the adjustment mechanism includes a movable part 1, which is suitable for being fixedly connected to the door guard plate 4; and also includes a driving component 2, which is suitable for being fixedly connected to the vehicle door outer panel 3, and the driving component 2 is provided with a receiving groove 21 for receiving the door guard plate 4. The movable part 1 can move under the drive of the driving component 2 to drive the door guard plate 4 to slide along the extension direction of the receiving groove 21.

[0045] By setting the receiving groove 21, the door guard plate 4 is no longer in single-point contact with the adjustment mechanism, but is in multi-point contact with the door guard plate 4 and the receiving groove 21, which increases the stability of the connection between the adjustment mechanism and the door guard plate 4 during adjustment, thereby improving the adjustment accuracy.

[0046] Specifically, according to some embodiments of the present invention, two receiving slots 21 are provided, the two receiving slots 21 extend in the same direction, and the two receiving slots 21 extend in the vertical direction. The drive assembly 2 includes a housing, and the receiving slots 21 are provided on the housing, and the receiving slots 21 are provided at the left and right ends of the housing, and the two receiving slots 21 extend in the vertical direction. A hole for installing an adjustment mechanism is provided on the door guard 4. When the door guard 4 needs to be adjusted up and down in the vertical direction, the edge of the door guard 4 at the opening position is placed in the receiving slots 21 at the left and right ends of the housing. When the up and down position of the door guard 4 is adjusted, the door guard 4 moves up and down along the left and right receiving slots 21.

[0047] In some other embodiments, the door guard plate 4 can also be adjusted in the horizontal direction or at a certain angle to the horizontal direction, and the extending direction of the accommodating groove 21 is consistent with the direction in which the door guard plate 4 needs to be adjusted.

[0048] According to some embodiments of the present invention, the driving assembly 2 includes a driving member 22 , and the driving member 22 is connected to the movable member 1 .

[0049] Specifically, such as Figure 4 As shown, the driving member 22 includes a rotating shaft 221 and an eccentric portion 222. The eccentric portion 222 is cylindrical. The axis of the rotating shaft 221 connecting the movable member 1 to the eccentric portion 222 is parallel to and does not overlap the axis of the eccentric portion 222. The first end of the rotating shaft 221 is connected to the vehicle door outer panel 3. The first end of the rotating shaft is provided with a latch that connects to the vehicle door outer panel 3. The latch connects one end of the rotating shaft to the vehicle door outer panel 3. The eccentric portion 222 is connected to the second end of the rotating shaft 221, allowing the rotating shaft 221 to rotate axially. The movable member 1 is connected to the eccentric portion 222. Therefore, when the rotating shaft 221 rotates axially, the eccentric portion 222 rotates axially along the rotating shaft 221, causing the eccentric portion 222 to displace, driving the movable member 1 to move. Since the movable member 1 is fixedly connected to the door guard plate 4, the movement of the movable member 1 drives the movement of the door guard plate 4. At least one screw hole 12 is provided on the movable member 1. This screw hole 12 is used to insert a screw to securely connect the movable member 1 to the door panel 4. Multiple screw holes 12 may be provided, as long as a stable connection between the movable member 1 and the door panel 4 is achieved. The movable member 1 and the door panel 4 may be connected in a variety of ways, such as by snapping or welding, as long as the connection between the movable member 1 and the door panel 4 is secure.

[0050] According to some embodiments of the present invention, Figure 2 、 Figure 4 As shown, the movable member 1 is provided with an adjustment hole 11, through which the movable member 1 is sleeved on the eccentric portion 222. The adjustment hole 11 is rectangular, and the margin of the adjustment hole 11 in the first direction is equal to the diameter of the eccentric portion 222. The margin of the adjustment hole 11 in the second direction is greater than or equal to the diameter of the circle formed by the rotation of the eccentric portion 222 in the second direction. The first direction is the preset adjustment direction of the door guard plate 4.

[0051] Specifically, when the eccentric portion 222 is displaced, it moves along the preset adjustment direction of the door guard 4 and also in a direction at an acute angle to the preset adjustment direction. To precisely adjust the position of the door guard 4, the preset adjustment direction of the door guard 4 can be set to a vertical direction, so that the distance the movable member drives the door guard to move is equal to the distance the eccentric portion moves along the door guard's movement direction. Therefore, the vertical margin of the adjustment hole 11 is set to be equal to the diameter of the eccentric portion 222, and the horizontal margin of the adjustment hole 11 is greater than the maximum horizontal distance of the eccentric portion 222's movement range. This arrangement ensures that when the eccentric portion 222 moves, it drives the movable member 1 only in the vertical direction, without causing it to move horizontally or in any other direction at a certain angle to the horizontal direction. This ensures that the door guard 4 moves only in the vertical direction, resulting in more accurate adjustment of the door guard 4.

[0052] In some other embodiments, the preset adjustment direction of the door guard plate 4 can be set to the horizontal direction or another direction at an acute angle to the horizontal direction, and the margin of the adjustment hole 11 along the preset adjustment direction of the door guard plate 4 can be equal to the diameter of the eccentric portion 222. The adjustment hole 11 can also be set to any shape other than a rectangle, as long as the eccentric portion 222 moves to drive the movable member 1 to move only along the preset adjustment direction of the door guard plate 4. The preset adjustment direction of the door guard plate 4 can be set arbitrarily. When the door guard plate 4 needs to be adjusted in multiple directions, the number of adjustment mechanisms can be set to equal the number of adjustment directions, and the multiple adjustment mechanisms can adjust the door guard plate 4 in different directions.

[0053] like Figure 5 、 Figure 6 As shown, according to some embodiments of the present invention, the housing includes a first housing 23 and a second housing 24. The first housing 23 is sleeved on the rotating shaft 221. The second housing 24 is connected to the first housing 23 to form an accommodating cavity. The eccentric portion 222 is disposed in the accommodating cavity. At least a portion of the movable member 1 is disposed in the accommodating cavity. The accommodating groove 21 is disposed on the first housing 23. In some other embodiments, the accommodating groove 21 may also be disposed on the second housing 24.

[0054] Specifically, the first shell 23 is provided with four latching protrusions 233, and the second shell 24 is provided with four latching grooves 241 cooperating with the latching protrusions 233. By setting the first shell 23 and the second shell 24 to be connected to each other and form a accommodating cavity, the movable part 1 can only move along the preset adjustment direction of the door guard plate 4 and will not fall off from the eccentric part 222, thereby realizing the limitation of the movable part 1.

[0055] like Figure 5 、 Figure 6As shown, according to some embodiments of the present invention, the first housing 23 is provided with an arcuate groove 231, and the eccentric portion 222 is provided with a protrusion 2221. When the rotating shaft 221 is inserted into the first housing 23, the protrusion 2221 can be accommodated in the arcuate groove 231, so that the protrusion 2221 slides within the arcuate groove 231 when the rotating shaft 221 rotates. The arrangement of the protrusion 2221 and the arcuate groove 231 ensures that when the rotating shaft 221 rotates, the protrusion 2221 rotates within the arcuate groove 231 without deviation, thereby increasing the stability of the rotation of the rotating shaft 221, thereby ensuring stable movement of the movable member 1 and improving the adjustment accuracy of the door guard plate 4.

[0056] According to some embodiments of the present invention, the driving member 22 further includes an adjusting portion 224 connected to an end of the eccentric portion 222 away from the rotating shaft 221 , and the first housing 23 is provided with a through hole 242 for accommodating the adjusting portion 224 to expose the adjusting portion 224 .

[0057] Specifically, when the rotating shaft 221 needs to rotate, a rotational force must first be applied to the adjusting portion 224. This rotational force causes the adjusting portion 224 to rotate, thereby driving the rotating shaft 221 and the eccentric portion 222 to rotate. Specifically, the adjusting portion has a hexagonal cross-section along its axis. During adjustment, a hexagon socket can be used to apply a rotational force to the adjusting portion, thereby achieving rotation of the rotating shaft and the eccentric portion. In some other embodiments, the adjusting portion can also be configured as other shapes. During adjustment, an adjustment tool that matches the shape of the adjusting portion is selected to apply a rotational force to the adjusting portion for adjustment.

[0058] like Figure 8 As shown, in some other embodiments, the maximum distance between the outer edges of the eccentric portion 222 and the adjustment portion 224 is x. By setting different x values, the adjustment amount of the eccentric portion 222 can be adjusted to achieve different adjustment amount requirements. x can be 1mm, 2mm, 3mm or any other value that can adjust the adjustment amount of the eccentric portion 222 within the effective range.

[0059] According to some embodiments of the present invention, the first housing 23 is provided with at least one limiting protrusion 2321, and the driving member 22 is provided with at least one limiting groove 2231 that cooperates with the limiting protrusion 2321 to determine the rotational position of the driving member 22. The first housing 23 is provided with at least one elastic portion 232, and the limiting protrusion 2321 is provided on the elastic portion 232. The driving member 22 includes a positioning portion 223, one end of the positioning portion 223 is connected to the eccentric portion 222, and the other end is connected to the adjustment portion 224, and the limiting groove 2231 is provided on the positioning portion 223.

[0060] like Figure 5 、 Figure 6As shown, specifically, two elastic portions 232 are provided, one at each end of the first housing 23, four limiting grooves 2231 are provided, and the angle between two adjacent limiting protrusions 2321 on the positioning portion 223 and the center of the positioning portion 223 is 90 degrees. When the rotating shaft 221 rotates to a certain position, the movable member 1 is at the lowest point of the adjustable range. At this time, the two opposite limiting protrusions 2321 respectively engage with the two limiting grooves 2231, and the adjustment mechanism produces a snapping sound, indicating that the adjustment has reached the lowest point. When the rotating shaft 221 rotates in the opposite direction to place the movable member 1 at the highest point of the adjustable range, the elastic portion 232 deforms until the other two opposite limiting grooves 2231 respectively engage with the two limiting protrusions 2321, and the adjustment mechanism produces a snapping sound, indicating that the adjustment has reached the highest point.

[0061] According to specific needs, the number of the limiting grooves 2231 on the adjustment part 224 can be set to multiple, and the multiple limiting grooves 2231 are opposite to each other. Each pair of limiting grooves 2231 can mark the rotation position of a rotating shaft 221 and thus mark the height of the movable part 1.

[0062] On the other hand, an embodiment of the present invention proposes a vehicle door, including a door guard plate 4 and a door outer panel 3, and the above-mentioned adjustment mechanism, wherein the door guard plate 4 is connected to the movable part, and the driving assembly is connected to the door outer panel 3. When adjusting the driving assembly, the door outer panel 3 provides support force for the driving assembly, so that the driving assembly drives the movable part to move, and then the movable part drives the door guard plate 4 to move.
