Detailed Description

Embodiments of the present utility model will be described in detail below, by way of example with reference to the accompanying drawings.

The following describes a slide rail assembly 100 according to an embodiment of the present utility model with reference to fig. 1 to 11, and the present utility model also proposes a seat, and further, a vehicle door.

Referring to fig. 1 to 4, a slide rail assembly 100 according to an embodiment of the present utility model includes: the first slide rail 10, the second slide rail 20, the stopper 30 and the stopper assembly 40.

A first slide groove 11 is provided in the first slide rail 10. The cross-sectional shape of the first slide rail 10 may be various, and may be partially modified according to other requirements of use.

Referring to fig. 8 and 1, the second slide rail 20 is disposed in the first slide groove 11 and slides in the first slide groove 11. Specifically, the second slide rail 20 can slide in the first slide groove 11, the first slide rail 10 and the second slide rail 20 are in sliding contact, and the contact part is made of plastic materials, so that abnormal sound caused by impact in the working process can be avoided on the premise of meeting the strength requirement.

The limiting member 30 is fixed in the first sliding groove 11, the limiting assembly 40 is disposed in the first sliding groove 11 and abuts against the second sliding rail 20, and specifically, the limiting assembly 40 includes: the platform 41 and the limiting pin 42, the limiting pin 42 moves up and down relative to the platform 41, so that the limiting pin 42 and the limiting piece 30 are selectively abutted. Specifically, the limiting component 40 is arranged in the first sliding groove 11 and is abutted against the second sliding rail 20, so that the internal space of the first sliding rail 10 is fully utilized, the whole framework is simple and compact, the volume of a product is reduced, and the installation requirement of more scenes can be met.

In addition, the stopper pin 42 can move up and down relative to the platform 41, and the stopper pin 42 and the stopper 30 can be selectively abutted. That is, the stopper pin 42 is divided into two states, one is a locked state, and one is an unlocked state, in which the stopper pin 42 cannot move up and down, when the stopper pin 42 moves to be in contact with the stopper 30, since the stopper 30 is fixed in the first chute 11 and cannot move, and since the stopper pin 42 cannot move up and down, the second slide rail 20 cannot move forward further when the stopper pin 42 and the stopper 30 abut against each other. In the unlocked state, the limiting pin 42 can move up and down, when the limiting pin 42 moves to abut against the limiting piece 30, if the second sliding rail 20 continues to move forward at this time, the limiting piece 30 pushes the limiting pin 42 to move upward, so that the second sliding rail 20 is enabled to move forward continuously. Also, during the movement in the unlocked state, there is no great resistance between the stopper 30 and the stopper pin 42, and the second slide rail 20 can be moved forward or backward in the first slide rail 10 with a small force.

The platform 41 may have different forms, and its shape may be adjusted according to different spaces. The limiting pin 42 can be in different forms, and the diameter and the bottom structure of the limiting pin 42 can be adjusted according to different requirements, so that the limiting pin can be flexibly applied to a plurality of scenes, and the purposes of universality and sharing are achieved.

And, the switching mode of the two states of the limiting pin 42 is to rotate the limiting pin 42 by 90 degrees clockwise or anticlockwise by using a tool, and specifically, the operating tool is an internal hexagonal wrench, so that the universality is high and the operating force is small. The outer ring of the limiting assembly 40 is provided with a plastic coating, so that abnormal sound generated by collision between the limiting assembly 40 and the first sliding rail 10 and the second sliding rail 20 in the operation process can be avoided.

Of course, the operating tool may be not only an allen wrench, but also other driving members for driving the stop pin 42.

Therefore, the limiting pin 42 can move up and down along with the platform 41, the limiting piece 30 is fixed in the first sliding groove 11, and the limiting assembly 40 is ensured to be conveniently and rapidly switched between the locking state and the unlocking state in the first sliding rail 10 on the basis of not changing the structure of the first sliding rail 10. And the product structure is simplified, the volume is minimized, and meanwhile, enough strength is ensured, so that the actual working requirement is met.

Referring to fig. 1-11, the spacing assembly 40 further includes: the limiting column 43 and the cover plate 44, the cover plate 44 and the platform 41 are fixedly connected, the limiting column 43 is arranged on the limiting pin 42, and the limiting column 43 and the cover plate 44 are selectively limited circumferentially or axially, so that the limiting pin 42 and the limiting piece 30 are selectively abutted. The stopper post 43 is installed in the stopper pin 42, and both ends are exposed to the same length.

When the limiting pin 42 is in the locking state, the limiting pin 42 cannot move upward in the height direction and cannot rotate around the axis of the limiting pin 42, and the second sliding rail 20 moves forward to enable the limiting pin 42 to abut against the limiting piece 30. When the limiting pin 42 is in the unlocking state, the limiting pin 42 can freely move in the height direction, the limiting pin 42 can move upwards when the second sliding rail 20 moves forwards until the limiting pin 42 contacts the limiting piece 30, and the second sliding rail 20 can move forwards continuously.

And, the cover plate 44 is fixedly connected with the platform 41 through the inner plum screw 45, so that the limiting assembly 40 is assembled into a whole. Specifically, the cover 44 is provided with mounting legs on both front and rear sides, with holes provided on the mounting legs, and mounting holes provided on the platform, and the inner plum screw 45 is screw-coupled with the mounting holes after passing through the holes, so that the cover 44 can be fixed on the platform 41.

In addition, the cover 44 is further provided with reinforcing ribs 46, so that the strength of the cover 44 can be enhanced. The reinforcing ribs 46 are not limited to one form, and may be circular, triangular, or rectangular. And, the material of the reinforcing ribs 46 is not limited to plastic, and cast aluminum or cast steel may be used instead.

Specifically, the first limit groove 47 and the second limit groove 48 are more than one and are spaced apart on the cover 44 with the center of the cover 44 as a center, that is, the first limit groove 47 cannot be beside the first limit groove 47, the second limit groove 48 is the same, and the second limit groove 48 has a certain depth in the height direction.

When the stopper pin 42 is in the locked state, the stopper post 43 is engaged in the first stopper groove 47, so that the movement of the stopper pin 42 in the height direction can be restricted. When the limiting pin 42 is in the unlocking state, the limiting post 43 is clamped in the second limiting groove 48, the second limiting groove 48 can limit the limiting pin 42 not to rotate around the axis of the limiting pin, but the limiting pin 42 can still move freely in the height direction due to the fact that the second limiting groove 48 has a certain depth in the height direction.

Referring to fig. 6-7, the spacing assembly 40 further includes: the elastic member 49 is provided with a receiving groove (reference numeral is not given) on the stopper pin 42, one end of the elastic member 49 is disposed in the receiving groove, and the other end of the elastic member 49 abuts against the stopper post 43. That is, the elastic member 49 is installed inside the stopper 30 and both ends are connected with the stopper post 43. Through setting up the elastic component 49 for when spacing post 43 slides to second spacing inslot 48 by first spacing groove 47, spacing post 43 stretches out under the effect of elastic component 49, thereby makes spacing post 43 can block in second spacing inslot 48.
