The limiting structure 5 is not on the same straight line as the first positioning pin 2 and the second positioning pin 3, and the three form a limiting surface, which can provide limiting for the constraint mechanism 1, and ensure that the constraint mechanism 1 can only move in the direction perpendicular to the constraint mechanism 1 (for example, Y direction movement), and will not displace in the direction parallel to the constraint mechanism 1 (for example, X direction displacement) with the movement of the hinge side bracket 4, thereby ensuring the consistency of the position of the constraint mechanism 1 in the direction perpendicular to the constraint mechanism 1, and improving the engagement performance of the constraint mechanism 1 and the lock catch 7.
[0058] In the example, the first positioning pin 2 and the second positioning pin 3 cooperate to limit the position of the constraint mechanism 1 in the direction parallel to the constraint mechanism 1, so as to ensure that the constraint mechanism 1 is always in a parallel state with the hinge side bracket 4, and ensure that the constraint mechanism 1 can only move in the direction perpendicular to the constraint mechanism 1 (for example, Y direction movement); in cooperation with the limiting structure 5, the position of the constraint mechanism 1 in the direction parallel to the constraint mechanism 1 is further limited, so as to ensure that the position of the constraint mechanism 1 relative to the hinge side bracket 4 in the direction perpendicular to the constraint mechanism 1 is always unchanged regardless of the matching relationship between the constraint device suitable for the sliding door and the hinge side bracket 4, thereby eliminating the assembly deviation of the constraint device suitable for the sliding door, avoiding the risk of poor engagement or even engagement failure of the constraint mechanism 1 and the lock catch 7 due to unstable assembly state of the sliding door, ensuring the matching precision of the constraint mechanism 1 and the lock catch 7, and enabling the constraint device suitable for the sliding door to normally lock and unlock, so as to achieve the locking or unlocking of the sliding door.
[0059] As an example, the sliding door assembly is applied to a vehicle, and compared with the structure of the previous vehicle model, the constraint device suitable for the sliding door is provided with two Y direction positioning pins and a Y direction limiting hole 16, which not only ensures that the engagement is in the Y direction, but also ensures that the Y direction position of the constraint device suitable for the sliding door is always unchanged relative to the vehicle body, thereby effectively improving the engagement performance of the constraint mechanism 1 and the lock catch 7 of the constraint device suitable for the sliding door, avoiding the risk of poor engagement or even engagement failure of the constraint mechanism 1 and the lock catch 7 due to unstable assembly state of the sliding door, improving the opening and closing quality of the sliding door, and especially helping to improve the quality of the business MPV sliding door.
