Conventionally, for MPV models with sliding door configuration, abnormal noise of an automobile sliding door in a sliding process and abnormal noise during running test under a closing state of the sliding door are frequently encountered. Generally, the lower sliding rail assembly is used as a main part for bearing and limiting a sliding door, and if the structure is unreasonable in design, the problems such as abnormal sound and the like can be directly caused.
In the vehicle evaluation, the sliding door is required to slide smoothly, and the sliding door is required to be matched tightly when closed. The lower sliding rail in the current market basically cannot meet the different requirements of the sliding section and the closing section, and when the sliding smoothness requirement is met, abnormal noise of the sliding door in the closing state is easy to occur; when the closed state is matched with the door body tightly, no abnormal sound exists, the sliding door slides to have resistance, and the blocking is possibly caused.
In view of this, the present invention provides a rail assembly, and fig. 1 to 6 are schematic views of an embodiment of a rail assembly according to the present invention, and the rail assembly will be described with reference to the specific drawings.
Referring to fig. 1 to 6, the guide rail assembly 100 is disposed on a guide rail assembly 1000 of an automobile 10000, and guides a sliding door 2000 to open and close, wherein the guide rail assembly 100 includes a guide rail 1, a guide rail groove 11 is concavely formed in the guide rail 1 for a sliding door 2000 guide wheel 2002 to be movably mounted, the guide rail groove 11 includes a straight line section 111 extending horizontally, a closing section 112 horizontally deflected by a certain angle relative to the straight line section 111, and a transition section 113 connecting the straight line section 111 and the closing section 112, the width of the straight line section 111 is a, the width of the closing section 112 is B, the transition section 113 smoothly transitions the straight line section 111 and the closing section 112, and a > B.
According to the technical scheme, the sliding door 2000 of the automobile 10000 is tightly matched when being closed and slides smoothly when being opened by adjusting and designing the structure of the guide rail 1. Specifically, the guide rail 1 includes the straight line section 111 for guiding the sliding door 2000 to cover the vehicle body for translational sliding, so the straight line section 111 extends horizontally, and a certain gap is formed between the side wall of the straight line section 111 and the guide wheel 2002 of the sliding door 2000, so that the sliding door 2000 is ensured to move smoothly; the guide rail 1 further comprises a closing section 112 where the guide wheel 2002 is located when the sliding door 2000 is embedded into the vehicle body after moving from the outer side of the vehicle body to approach the vehicle body, and the guide wheel 2002 reaches the closing section 112 after the sliding door 2000 is embedded into the vehicle body, so that the closing section 112 and the straight line section 111 are horizontally deflected by a certain angle. Above, the closing section 112 and the guide wheel 2002 are more tightly matched than the straight section 111 and the guide wheel 2002, so that the sliding door 2000 is tightly attached to the vehicle body while the straight section 111 moves smoothly, i.e. the width of the straight section 111 is a, and the width of the closing section 112 is B, where a > B. The width of the guide rail groove 11 is changed to achieve the difference of tightness degree of the matching between the guide rail groove 11 and the sliding door 2000 guide wheel 2002, so that the sliding door 2000 is smooth when moving, and is matched with a vehicle body tightly when closing, so that shaking is reduced or even avoided. On this basis, the transition section 113 is connected between the straight section 111 and the closing section 112 to form a complete guide rail 1, and the transition section 113 is arranged with a wide width so as to smoothly transition between the straight section 111 and the closing section 112, thereby ensuring that the sliding door 2000 guide wheel 2002 smoothly moves in the transition section 113.
It should be noted that, in this embodiment, the size of the sliding door 2000 guide wheel 2002 is set to be consistent with the width B of the closing section 112, so as to ensure that when the sliding door 2000 guide wheel 2002 is located in the closing section 112, no gap exists between the sliding door 2000 guide wheel and two side walls of the closing section 112, and when the vehicle is running, the sliding door 2000 guide wheel 2002 will not shake between the two side walls of the closing section 112, so as to achieve a tight fit between the sliding door 2000 and the vehicle body. Of course, the width B of the closing section 112 may be slightly larger than the size of the guide wheel 2002 of the sliding door 2000, so long as a > B is ensured, and the closing section also has the function of tightly matching and reducing shake. The specific size range of the width a of the straight line section 111 should be 103% or more of the size of the sliding door 2000 guide wheel 2002, that is, the gap between the straight line section 111 and the sliding door 2000 guide wheel 2002 should be 3% or more of the size of the sliding door 2000 guide wheel 2002, so that the sliding door 2000 guide wheel 2002 can be ensured to move smoothly in the straight line section 111, in this embodiment, the width a of the straight line section 111 is selected to be 103% of the size of the sliding door 2000, the excessively large width a of the straight line section 111 may cause the guide rail 1 to be excessively large, increasing the cost, and the excessively large size may also cause the situation that the straight line section 111 cannot guide the sliding door 2000 guide wheel 2002. Specifically, the sliding door 2000 guide pulley 2002 in this embodiment is set to 20mm in size, the width B of the closing section 112 is 20mm, and the width a of the straight section 111 is 20.6mm.
In addition, the width of the transition section 113 may be gradually reduced from one end of the straight section 111 to one end of the closing section 112, or may be gradually reduced from a to B while the width of a partial section thereof is kept uniform; and the transition section 113 may be set to be an arc-shaped whole section, or may be set to be a combination of an arc-shaped section and a straight-line section. The present invention is not limited thereto, as long as smooth transition between the straight section 111 and the closed section 112 is achieved. In this embodiment, the transition section 113 is configured to combine an arc section with a straight line section, and the width of the arc section is gradually reduced from a to B, and the width of the straight line section is maintained as B.
When the sliding door 2000 is opened to the maximum opening, there is a case that the maximum opening of the sliding door 2000 needs to be maintained, and in order to facilitate the use under this condition, the present invention proposes the following scheme without affecting the normal movement of the sliding door 2000 in the straight line section 111: the straight line section 111 has a first end far away from the transition section 113, a stop component 2 is disposed near the first end, the stop component 2 and the first end define a limit section 111a, and the limit section 111a is used for limiting a sliding door 2000 guide wheel 2002 moving to the limit section 111 a. When the sliding door 2000 guide wheel 2002 moves to the first end of the straight line section 111, that is, the sliding door 2000 is at the maximum opening, at this time, one side of the sliding door 2000 guide wheel 2002 near the transition section 113 is provided with the stop assembly 2 to stop the sliding door 2000 guide wheel 2002, so as to position the sliding door 2000 at the maximum opening, thereby meeting the above requirements. Of course, the stop assembly 2 does not have to limit the sliding door 2000 to the maximum opening, and the stop assembly 2 and the first end define the limiting section 111a therebetween, so as to limit the guide wheel 2002 of the sliding door 2000 in the limiting section 111 a. And a plurality of stop assemblies 2 can be further arranged to form a plurality of different stop sections 111a, so as to realize the stop of different requirements of the sliding door 2000.
Specifically, the stop assembly 2 includes a base 21 and a spring 22, and the base 21 is fixed to one side of the guide rail 1; the spring 22 is mounted on the base 21 and extends along the straight line section 111, a protrusion 221a is protruding from the middle of the spring 22, and the protrusion 221a extends from one side of the guide rail 1 to the guide rail groove 11, so as to form a stop portion 221 for stopping the sliding door 2000 guide wheel 2002 located in the limit section 111 a. The stop component 2 can be arranged to fix a manually operated stop piece on the guide rail 1 to limit the guide wheel 2002 of the sliding door 2000; the sliding door 2000 can also be electrically operated stop devices, and the stop parts are controlled to extend to the guide rail grooves 11 to be abutted with the guide wheels 2002 of the sliding door 2000 by a control program, so that the sliding door 2000 is limited. In this embodiment, the stop assembly 2 is configured to fix the spring 22 on one side of the guide rail 1 by the base 21, the protrusion 221a of the spring 22 protrudes to a position corresponding to the guide rail groove 11 and can contact the guide wheel 2002 of the sliding door 2000 passing by, because the spring 22 has a certain elasticity, when pushing the sliding door 2000 to make the guide wheel 2002 pass by the protrusion 221a, the guide wheel 2002 presses the protrusion 221a to deform and separate from the guide rail groove 11, and the guide wheel 2002 can move across the protrusion 221a without affecting the normal opening and closing of the sliding door 2000. When the sliding door 2000 is not driven by an external force, the guide wheel 2002 is stopped by the protrusion 221a, so that the guide wheel 2002 is limited at the limiting section 111a, thereby limiting the sliding door 2000.
Further, a relief groove 114 is formed on the side wall of the guide rail groove 11 opposite to the stop portion 221, and the stop portion 221 extends into the guide rail groove 11 from the relief groove 114. The side wall of the guide rail groove 11 is provided with the avoidance groove 114, and the stop part 221, that is, the protruding part 221a extends into the guide rail groove 11 from the avoidance groove 114, so as to stop the guide wheel 2002 of the sliding door 2000. On the one hand, the reed 22 is clamped on the outer side walls of the base 21 and the guide rail groove 11, so that the limit of the reed 22 in one direction is realized, and the reed 22 is convenient to set; on the other hand, the reed 22 and the base 21 are attached to the guide rail 1, so that space occupation is reduced.
Still further, an inserting portion 222 is convexly disposed on the reed 22, a limiting groove 211 is disposed on the base 21 corresponding to the inserting portion 222, and the inserting portion 222 is inserted into the limiting groove 211 to limit the reed 22 to move along the extending direction of the guide rail 1; and/or, the base 21 is provided with a plurality of limiting structures 212 corresponding to the two sides of the reed 22, so as to abut against and limit the movement of the reed 22 in the height direction of the guide rail groove 11. The stop part 221 on the reed 22 needs to be deformed to achieve its function in use, so that only a limiting or partial fixing mode can be adopted when the reed 22 is installed.
