Detailed Description

As shown in fig. 1 to 3, a slide rail mechanism 20 according to an embodiment of the present invention includes a rail 22 and a buffer device 24.

The rail 22 includes a longitudinal wall 26 and a supporting portion 28, wherein the supporting portion 28 is substantially vertically connected to the longitudinal wall 26, and the longitudinal wall 26 and the supporting portion 28 together define a supporting path L for providing a bottom 74 and a side 78 of a supporting object 72 (as shown in fig. 7). Wherein, the support path L is in the longitudinal direction.

The damping device 24 is disposed on the rail 22. Preferably, the slide rail mechanism 20 further comprises an auxiliary member 30 connected to the rail member 22. The auxiliary member 30 has a connecting portion 32 and an extending portion 34. The connecting portion 32 is connected (e.g., secured) to the longitudinal wall 26 of the rail member 22 by at least one first connecting feature 36; the extending portion 34 is bent relative to the connecting portion 32, and the extending portion 34 is substantially perpendicular to the connecting portion 32, but the embodiment is not limited thereto, and the extending portion 34 of the auxiliary member 30 and the supporting portion 28 of the rail member 22 are substantially parallel to each other.

As shown in fig. 1-4, the damping device 24 includes a base 38, a movable member 40, and a damping member 42. The base 38 is connected (e.g., affixed) to the longitudinal wall 26 of the rail member 22 by at least one second connecting feature 44, and thus, the base 38 can be considered part of the rail member 22. The moveable member 40 is longitudinally displaceable relative to the base 38. Here, it is exemplified that the base 38 includes a plurality of walls defining a longitudinal channel 45, and the movable member 40 is movably mounted to the longitudinal channel 45 of the base 38. In other embodiments, one of the moveable member 40 and the base 38 may include a longitudinal feature (e.g., a longitudinal hole or a longitudinal slot), and the other of the moveable member 40 and the base 38 may include a connector that extends through a portion of the longitudinal feature, as well as allowing the moveable member 40 to be longitudinally displaced relative to the base 38, and thus, is not limited in implementation.

The movable member 40 includes a longitudinal body 41 and a contact portion 46. The contact portion 46 corresponds to the support path L (shown in fig. 2). Preferably, the contact portion 46 is bent perpendicularly with respect to the longitudinal body 41, wherein the contact portion 46 is integrated into a contact member 48, and the contact member 48 is connected (e.g., fixedly connected) to the longitudinal body 41 of the moveable member 40 via at least one fixing feature 49, so that the contact member 48 can be considered as a part of the moveable member 40.

Preferably, the damping device 24 is disposed adjacent the rear end 22b of the rail member 22 (as shown in fig. 1).

Preferably, the damping device 24 is disposed above the adjacent rail member 22, and the contact portion 46 of the movable member 40 extends beyond the rear end 22b of the rail member 22 (as shown in fig. 1).

Preferably, the damping member 42 (shown in fig. 4) is disposed on one of the base 38 and the movable member 40, and here, taking the damping member 42 mounted on the base 38 as an example, in other implementation forms, the damping member 42 may also be mounted on the movable member 40 (not shown), so that the implementation is not limited.

The buffer 42 includes a first member 50 and a second member 52 that are movable relative to each other (see fig. 4 and 5). Here, the first member 50 is taken as a cylinder and the second member 52 is taken as a piston rod, but the implementation is not limited thereto. Wherein, the first member 50 contains a buffering medium (such as liquid or oil) and/or an elastic structure (such as a spring or an elastic object), a portion of the second member 52 is disposed inside the first member 50, and the second member 52 provides a force in response to the buffering medium, so that the other portion of the second member 52 is kept protruding to the outside of the first member 50 and is in a buffering preparation state. Since the buffering principle of the buffering member 42 is within the scope that can be understood by those skilled in the art, it is not described herein for brevity.

Preferably, as shown in fig. 4 and 5, the damping device 24 further includes a mounting seat 54. The mounting seat 54 has a chamber 55 for accommodating the first member 50, and the first member 50 is blocked (or limited) between a first blocking wall 53a and a second blocking wall 53b of the mounting seat 54; on the other hand, the other portions of the second member 52 are located outside the chamber 55 of the mounting seat 54.

Preferably, the mounting base 54 has at least one mounting feature 56 (e.g., protrusion) for mounting to at least one corresponding feature 58 (e.g., hole or slot) of the base 38, such that the bumper 42 can be mounted to the base 38 via the mounting base 54.

Preferably, as shown in fig. 4, the second member 52 has a supporting portion 59 corresponding to a contact end 61 of the movable member 40, such as an end of a wall of the movable member 40. Here, it is taken as an example that the abutting portion 59 and the contact end 61 are substantially located at the same longitudinal level.

Preferably, the sliding track mechanism 20 further includes an elastic member 60 for providing an elastic force to the movable member 40. Here, the elastic member 60 is a spring and is installed between a first installation portion 62 of the base 38 and a second installation portion 64 of the movable member 40, but the embodiment is not limited thereto.

As shown in fig. 6, in a rack system, two slide rail mechanisms 20 have substantially the same structural configuration, and the two slide rail mechanisms 20 are respectively disposed on a first side and a second side (e.g., the left side and the right side corresponding to each other) of a rack. A front bracket 66 and a rear bracket 68 are respectively disposed at the front end 22a and the rear end 22b of the rail 22 of each adjacent slide rail mechanism 20, and the front bracket 66 and the rear bracket 68 are used to mount the rail 22 to a front column 70a and a rear column 70b of the rack. The rail members 22 (e.g., the first rail member and the second rail member) of the two slide rail mechanisms 20 together define a supporting space S therebetween. The contact portion 46 of the movable member 40 corresponds to the support path L, and thus necessarily also corresponds to the support space S.

As shown in fig. 6 and 7, the carrier 72 can be accommodated in the supporting space S. The rail member 22 of each slide rail mechanism 20 can be used to carry the carrier 72 through the supporting portion 28. Preferably, the bottom 74 of the carrier 72 can be supported by the support portions 28 of the rails 22 (e.g., the first and second rails), and the top 76 of the carrier 72 can be supported by the extension portion 34 of the auxiliary member 30. In addition, the side portions 78 of the support 72 can be supported by the longitudinal walls 26 of the auxiliary element 30.

As shown in fig. 8, the rail member 22 of the slide mechanism 20 can be mounted to the front column 70a and the rear column 70b of the rack via the front bracket 66 and the rear bracket 68. Wherein, the rear portion 80 of the carrier 72 has a longitudinal distance X from the contact portion 46 of the movable member 40. It should be noted that the auxiliary member 30 is omitted from fig. 8.

As shown in fig. 8 and 9, the bottom 74 of the support 72 can be supported by the support portion 28 of the rail 22. When the carrier 72 is pushed from the outside of the frame toward the inside of the frame by an external force applied to the carrier in a first direction D1, the rear portion 80 of the carrier 72 contacts the contact portion 46 of the movable member 40, the buffer member 42 can generate a buffering effect in response to the displacement of the movable member 40 along the first direction D1, and the buffer member 42 is used to slow down the displacement speed of the movable member 40 toward the first direction D1, so that the displacement speed of the carrier 72 toward the first direction D1 can be effectively slowed down. On the other hand, since the movable member 40 is displaced from a first position P1 in fig. 8 to a second position P2 in fig. 9, the elastic member 60 accumulates elastic force in a second direction D2 in response to the displacement of the movable member 40 in the first direction D1. The second direction D2 is opposite to the first direction D1.

Further, once the rear portion 80 of the bearing object 72 contacts the contact portion 46 of the movable element 40, the bearing object 72 can drive the movable element 40 to move from the first position P1 to the second position P2 in the first direction D1, so that the contact end 61 of the movable element 40 impacts the abutting portion 59 of the second member 52, and the second member 52 and the first member 50 contract relatively to generate the buffering effect F (as shown in fig. 9), so as to slow down the moving speed of the bearing object 72 in the first direction D1 or reduce noise generated when the rear portion 80 of the bearing object 72 contacts the contact portion 46 of the movable element 40.

As shown in fig. 10, once the carrier 72 is displaced away from the contact portion 46 of the movable member 40 (fig. 10 illustrates that the carrier 72 is detached from the rail member 22), the elastic member 60 can release the elastic force in the second direction D2, so that the movable member 40 can be displaced in the second direction D2 in response to the elastic force to help the movable member 40 return to the first position P1 (fig. 10). That is, in a preferred embodiment, the elastic force of the elastic element 60 in the second direction D2 is negligible against the force of the carrier 72 moving in the first direction D1, and the elastic element 60 is configured to mainly drive the movable element 40 from the second position P2 to the first position P1 as a ready position for next buffering. It should be noted that the buffer member 42 itself is also resilient to allow the second member 52 of the buffer member 42 to extend to a maximum position relative to the first member 50. The present embodiment preferably allows the buffering member 42 to quickly return to its original working position by the arrangement of the elastic member 60. Accordingly, it should be understood that the arrangement of the elastic member 60 is only an assisting role, and is not necessarily arranged.

In other words, once the carrier 72 is detached from the rail 22 or the carrier 72 is displaced to be spaced apart from the contact portion 46 of the movable member 40 by a distance greater than the distance between the second position P2 and the first position P1, the movable member 40 returns from the second position P2 to the first position P1 in response to the elastic force of the elastic member 60 in the second direction D2. It should be noted that when the movable member 40 is at the first position P1, the other portion of the second member 52 of the damper 42 is extended relative to the first member 50 to be in the damping ready state again (as shown in fig. 10 or fig. 8).

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are: when the movable member 40 moves in the first direction D1, the buffering action F of the buffering element 42 can be generated. According to this configuration, once the rail member 22 carries the carrier 72, and the carrier 72 is displaced in the first direction D1, the movable member 40 is also displaced in the first direction D1, so that the buffer element 42 generates the buffering effect F on the carrier 72. The elastic element 60 is configured to provide an elastic force in the second direction D2 to the movable element 40 to assist the movable element 40 to return from the second position P2 to the first position P1 as a ready position for the next buffering of the buffering element 42. The second direction D2 is opposite to the first direction D1.

Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
