Slide rail buffer assembly

Abstract

The present invention relates to a slide rail buffer assembly comprising: a fixed bracket, a movable bracket, an adjusting bracket, a return spring, an adjusting member, and a resetting member. Both the movable bracket and the adjusting bracket are movably connected to the fixed bracket. The return spring is stretchable and deformable by the movable bracket and the adjusting bracket, thus having an installation length. Furthermore, the adjusting member can move and rotate within the fixed bracket. When the adjusting member moves, its female engagement portion can selectively disengage from the male engagement portion of the fixed bracket. When the adjusting member rotates, the adjusting bracket can move to adjust the installation length. The resetting member applies a resetting force to the adjusting member, keeping the male and female engagement portions engaged. When the adjusting member moves in the unlocking direction, the male and female engagement portions can separate, allowing the adjusting member to rotate and adjust the installation length. Therefore, even if the return spring generates varying return forces, the male and female engagement portions remain engaged to prevent accidental rotation of the adjusting member.

Claims

1. A slide rail buffer assembly, comprising: a fixed bracket having a track portion and a connecting portion, the connecting portion having a connecting space and a male engaging portion located inside the connecting space; a movable bracket movably connected to the track portion; an adjusting bracket movably connected to the connecting portion; and a return spring disposed on the movable bracket and the adjusting bracket, such that the return spring can deform to form an installation length; An adjusting member has a female engaging portion that engages with the male engaging portion and is movably connected to the connecting portion, allowing the adjusting member to move and rotate freely within the connecting space. When the adjusting member moves relative to the fixed bracket, the female engaging portion selectively engages or disengages from the male engaging portion. When the adjusting member rotates relative to the fixed bracket, it drives the adjusting bracket to move, thus changing the installation length. A resetting member is disposed in the connecting portion and generates a resetting force acting on the adjusting member. This resetting force allows the adjusting member to move along an engaging direction, thereby maintaining the engagement of the female and male engaging portions through the resetting force. This locks the adjusting member in a locked state, preventing it from rotating relative to the fixed bracket, and thus preventing the adjusting bracket from moving to adjust the installation length. The aforementioned adjusting member moves along an unlocking direction opposite to the aforementioned engaging direction, causing the aforementioned female engaging part to separate from the aforementioned male engaging part, thereby allowing the aforementioned adjusting member to be in a free state to adjust the length of the aforementioned installation length.

2. The slide rail buffer assembly as described in claim 1, wherein, One end of the connecting portion is provided with an exposed hole communicating with the connecting space. Inside the connecting space, there are perforations spaced apart from the exposed hole and a stop surface that can contact the adjusting member. The connecting space is divided into a first connecting area and a second connecting area through the perforations. The first connecting area communicates with the exposed hole, and the second connecting area communicates with the first connecting area through the perforations. Both the male engaging portion and the stop surface are located inside the first connecting area. One of the male engaging portion and the stop surface is located around the exposed hole, and the other is located around the perforations. The adjusting member passes through the perforations, such that a portion of the adjusting member is located inside the first connecting area and is configured as a disc portion, while the remaining portion of the adjusting member is located inside the second connecting area and is configured as a shaft portion. The female engaging portion is formed on the disc portion. When the adjustment member is in the locked state, the disc is spaced apart from the stop surface. During the process of the adjustment member switching from the locked state to the free state, the disc moves along the unlocking direction to approach the stop surface, so that the disc can contact the stop surface to limit the axial displacement of the adjustment member.

3. The slide rail buffer assembly as described in claim 2, wherein, The aforementioned fixing bracket has a fixing body with the aforementioned perforated hole and an outer cover body with the aforementioned exposed hole. A portion of the aforementioned fixing body is configured as the aforementioned track portion, while the remaining portion of the aforementioned fixing body is fastened to the aforementioned outer cover body to jointly form the aforementioned connecting portion.

4. The slide rail buffer assembly as described in claim 1, wherein, The aforementioned male engagement portion is provided with a grooved guide surface and a grooved positioning surface intersecting the grooved guide surface. When the aforementioned adjusting member rotates forward, the aforementioned female engagement portion can move along the grooved guide surface, causing the aforementioned adjusting member to move synchronously along the aforementioned unlocking direction. Consequently, the aforementioned female engagement portion can separate from the aforementioned male engagement portion, allowing the aforementioned adjusting member to switch to the aforementioned free state. When the aforementioned adjusting member rotates in reverse, the aforementioned female engagement portion will contact the aforementioned grooved positioning surface, causing the aforementioned grooved positioning surface to stop the aforementioned adjusting member from rotating in reverse, thereby keeping the aforementioned adjusting member in the aforementioned locked state.

5. The slide rail buffer assembly as described in claim 4, wherein, When the female engaging part contacts the groove positioning surface, the adjusting member overcomes the resetting force of the resetting member and moves along the unlocking direction to switch to the free state. Then the adjusting member rotates to change the length of the installation length.

6. The slide rail buffer assembly as described in claim 4, wherein, The aforementioned male engaging portion is provided with a plurality of engaging grooves, while the aforementioned female engaging portion is provided with a engaging protrusion. The plurality of engaging grooves are arranged in a ring-shaped interval with each other, and each of the aforementioned engaging grooves has the aforementioned groove guide surface and groove positioning surface. When the aforementioned adjusting member is in the aforementioned locked state, the aforementioned engaging protrusion can penetrate into the interior of one of the aforementioned engaging grooves through the reset force of the aforementioned reset member, so that the aforementioned adjusting member is temporarily unable to rotate 360 ​​degrees relative to the aforementioned fixed bracket.

7. The slide rail buffer assembly as described in claim 4, wherein, The aforementioned male engagement portion further has a groove contact surface that can contact the aforementioned female engagement portion when the aforementioned adjustment member is in the aforementioned locked state. The groove guide surface and the aforementioned groove positioning surface are formed on opposite sides of the aforementioned groove contact surface. An obtuse angle is formed between the aforementioned groove guide surface and the groove contact surface, while an acute angle or a right angle is formed between the aforementioned groove positioning surface and the groove contact surface.

8. The slide rail buffer assembly as described in claim 1, wherein, The aforementioned male engagement part is provided with two parallel groove positioning surfaces. When the aforementioned male engagement part and female engagement part are engaged with each other, the aforementioned female engagement part is located between the two aforementioned groove positioning surfaces to restrict the aforementioned adjusting member from rotating relative to the aforementioned fixed bracket. This means that the aforementioned adjusting member must first move along the aforementioned unlocking direction to switch to the aforementioned free state before the aforementioned adjusting member can rotate to change the aforementioned installation length.
