Abstract
Description
Technical Field
[0001] This utility model relates to a slide rail assembly with a deceleration mechanism, particularly a frame adapted to an industrial servo, which uses a deceleration mechanism to cause one slide rail to retract and move relative to another slide rail to the end of its stroke, switching from rapid displacement to deceleration to the end of the stroke. Background Technology
[0002] In existing industrial server racks, the slide rail assembly of the reduction gear mechanism moves its entire distance relative to another slide rail. The slide rail stops moving relative to the other slide rail by abutting against each other using stop components or integrated stop points mounted separately on each slide rail. However, the servers supported by these industrial server slide rails are becoming increasingly heavy. The aforementioned method of stopping movement causes the stop components or stop points on the slide rails to deform and become damaged, and generate noise, due to the force applied by the user and the weight of the server. Therefore, how to solve the problem of damage and noise from the stop components or stop points used to stop slide rail movement due to the force applied by the user is a direction that industry professionals urgently need to research and improve. Summary of the Invention
[0003] This utility model relates to a slide rail assembly with a deceleration mechanism, comprising: a first rail, one end of which is bent and extended to form a first joint; a second rail, which is displaced relative to the first rail; and a deceleration mechanism having at least one movable member, a guide member, and a displacement member. The at least one movable member is disposed on the second rail, the guide member is movably mounted on one side of the first rail, and one side of the guide member has a plurality of guide features corresponding to the at least one movable member. A first groove is formed in the guide member, and a second joint is protruding at one end of the first groove. The displacement member is respectively mounted at both ends of the first joint and the second joint. When the second rail is displaced relative to the first rail in a first direction, the at least one movable member is displaced by the second rail and abuts against the guide feature. When the guide member moves synchronously in the first direction, the guide member compresses the displacement member to generate a thrust, thereby decelerating the displacement of the second rail relative to the first rail.
[0004] Preferably, the second rail is displaced relative to the first rail in a second direction opposite to the first direction. The at least one movable member is displaced by the second rail and moves in the second direction. The displaced member is reset by the thrust and drives the guide member to move synchronously in the second direction, so that the plurality of guide features of the guide member abut against and push the at least one movable member, thereby accelerating the displacement of the second rail relative to the first rail. When the second rail continues to displace, the at least one movable member disengages from the guide feature.
[0005] Preferably, the guide is a rack, and the at least one moving member is a damping gear that meshes with a plurality of teeth of the rack.
[0006] Preferably, the guide is a block, and the at least one movable member is a rolling bearing, which presses against a plurality of arcuate features of the block.
[0007] Preferably, the displacement element is one of a spring, a hydraulic rod, or a pneumatic rod.
[0008] Preferably, one end of the second rail is recessed inward with a first frame groove, and at least one second frame groove is recessed on one side of the first frame groove. The at least one movable member is disposed in the at least one second frame groove, and the guide member is aligned with the first frame groove.
[0009] Preferably, the guide member has the first groove, and one end of the first rail has a second groove. One end of the second groove is bent and extends into the first joint portion. The first joint portion is far away from the first groove. The first groove corresponds to the second groove, and the displacement member is disposed in the first groove.
[0010] Preferably, the guide member has at least one clearance hole at at least one end, and the first rail has at least one positioning member. The at least one positioning member passes through the at least one clearance hole and is then locked to one end of the first rail. When the displacement member is compressed and reset, the guide member is displaced to the point where the at least one positioning member of the first rail abuts against both ends of the at least one clearance hole to form a limit, thereby preventing the guide member from moving relative to the first rail.

[0043] Please see Figure 1 and Figure 2 As shown, this utility model is a slide rail assembly with a deceleration mechanism, comprising: a first rail 1, a second rail 2, a third rail 3 and a deceleration mechanism 4. The deceleration mechanism 4 is provided at one end of the first rail 1. The second rail 2 can be displaced relative to the first rail 1. The second rail 2 is movably installed between the third rail 3 and the first rail 1. The second rail 2 is used to extend the displacement length of the third rail 3 relative to the first rail 1. The structure, displacement, unfolding and retraction of the first rail 1, the second rail 2 and the third rail 3 are already known technologies, and will not be described in detail here for the sake of simplicity.
[0044] Please see Figure 3 As shown, the first rail 1 has a second groove 12 at one end, and the second groove 12 has a first connecting part 13 that is bent and extended at one end. The first rail 1 has at least one positioning member 11, and the second rail 2 has a first frame groove 21 recessed inward at one end, and at least one second frame groove 211 is recessed on one side of the first frame groove 21.
[0045] Please see Figure 4 and Figure 7 As shown, the deceleration mechanism 4 has at least one movable member 41, one guide member 42, and one displacement member 43. The at least one movable member 41 is disposed on the second rail 2 and is disposed in at least one second frame groove 211 on one side of the first frame groove 21. The guide member 42 is movably mounted on one side of the first rail 1 and is aligned with the first frame groove 21. A plurality of guide features 421 corresponding to the at least one movable member 41 protrude from one side of the guide member 42. At least one end of the guide member 42 is provided with at least one allowable... The positioning hole 422 is through which at least one positioning member 11 (e.g., a height-equalizing rivet) passes and is then locked to one end of the first rail 1. A first groove 423 is formed in the guide member 42, which corresponds to the second groove 12. A second joint portion 4231 protrudes from one end of the first groove 423. The two ends of the displacement member 43 are respectively installed on the first joint portion 13 and the second joint portion 4231, and the other end of the first joint portion 13 is away from the second groove 12.
[0046] This utility model is described using at least one movable member 41 as an example. The number of movable members 41 may be two, three or four. This example is not intended to limit the patent scope of this utility model.
[0047] This utility model uses a spring, hydraulic rod, pneumatic rod, or other element that can be reset after being compressed under force as the displacement component 43. This utility model is described using a spring (compression spring) as an example. The example is not intended to limit the patent scope of this utility model.
[0048] In this invention, the displacement member 43 is disposed between the first groove 423 and the second groove 12. The at least one movable member 41 is a damping gear, and the guide member 42 is a rack. The at least one damping gear meshes with a plurality of teeth of the rack. This is for illustrative purposes only. The displacement member 43 may be disposed within the first groove 423. The at least one movable member 41 may be a rolling bearing (not shown in the figure), and the guide member 42 may be a block (not shown in the figure). The rolling bearing presses against a plurality of arcuate features of the block. The at least one movable member 41 may be other elements with movable rotation. The positioning member 11 may be a bolt or other elements with equal-height locking. This embodiment is not intended to limit the patent scope of this invention.
[0049] Please see Figure 8 and Figure 10 As shown, when the slide rail assembly of the deceleration mechanism retracts, the second rail 2 displaces relative to the first rail 1 in a first direction D1. The second rail 2 drives the at least one movable member 41 to displace, and the at least one movable member 41 abuts against the plurality of guiding features 421 of the guide member 42. When the guide member 42 simultaneously displaces in the first direction D1, the guide member 42 drives the displacement member 43 to compress between the first groove 423 and the second groove 12. After the displacement of at least one positioning member 11 of the first rail 1 abuts against one end of the at least one clearance hole 422 to form a limit, the guide member 42 stops moving in the first direction D1. When the second rail 2 continues to move in the first direction D1 relative to the first rail 1, the at least one movable member 41 continuously abuts against the plurality of guide features 421 of the guide member 42, and generates a thrust through the compression of the displacement member 43, so that the displacement of the second rail 2 relative to the first rail 1 is decelerated to the end of the stroke.
[0050] As described above, at least one movable member 41 is a damping gear, the guide member 42 is a rack, and the plurality of guide features 421 are teeth. When the guide member 42 is displaced to the point where at least one positioning member 11 of the first rail 1 abuts against one end of the at least one clearance hole 422 to form a limit, and the guide member 42 stops moving in the first direction D1, when the second rail 2 continues to move in the first direction D1 relative to the first rail 1, the at least one movable member 41 engages with the plurality of teeth 421 of the guide member 42. The at least one movable member 41 is pushed by the plurality of guide features 421 to generate rotation, forming a resistance, which decelerates the displacement of the second rail 2 relative to the first rail 1 to the end of the stroke.
[0051] In another embodiment of this utility model, the at least one movable member 41 is a rolling bearing (not shown in the figure), the guide member 42 is a block (not shown in the figure), and the plurality of guide features 421 are the plurality of arc-shaped protrusion features (not shown in the figure). Except for the rolling bearing pressing against the plurality of arc-shaped protrusion features (not shown in the figure) of the block, its mating components, structure, and direction of action are the same as those described in the previous paragraph, and will not be repeated here.
[0052] Please refer to the following: Figure 10 and Figure 11 As shown, when the slide rail assembly of the deceleration mechanism is deployed, the second rail 2 is displaced relative to the first rail 1 in a second direction D2 opposite to the first direction D1. The at least one movable member 41 is driven by the second rail 2 to move in the second direction D2. The displacement member 43 is reset by the thrust. The displacement member 43 drives the guide member 42 to move synchronously in the second direction D2, so that the plurality of guide features 421 of the guide member 42 abut against and push the at least one movable member 41, thereby accelerating the displacement of the second rail 2 relative to the first rail 1. The guide member 42 is displaced until the at least one positioning member 11 of the first rail 1 abuts against the other end of the at least one clearance hole 422 to form a limit. The guide member 42 stops moving in the second direction D2. When the second rail 2 continues to move, the at least one movable member 41 disengages from the guide feature 421 of the guide member 42.
[0053] As described above, at least one movable member 41 is a damping gear, the guide member 42 is a rack, and the plurality of guide features 421 are teeth. When the guide member 42 is displaced to the point where at least one positioning member 11 of the first rail 1 abuts against the other end of the at least one clearance hole 422 to form a limit, the at least one movable member 41 engages with the plurality of guide features 421 of the guide member 42. The at least one movable member 41 is pushed by the plurality of guide features 421 to generate rotation, forming resistance, thereby slowing down the displacement of the second rail 2 relative to the first rail 1. When the second rail 2 continues to displace, the at least one movable member 41 disengages from the plurality of guide features 421 of the guide member 42.
[0054] In another embodiment of this utility model, the at least one movable member 41 is a rolling bearing (not shown in the figure), and the guide member 42 is a block (not shown in the figure). The plurality of guide features 421 are arc-shaped convex features (not shown in the figure). Except for the at least one rolling bearing pressing against the plurality of arc-shaped convex features of the block (not shown in the figure), its mating components, structure, and direction of action are the same as described in the previous paragraph and will not be repeated here.
[0055] In view of this, the slide rail assembly with a deceleration mechanism disclosed in this utility model has at least one movable member 41, one guide member 42, and one displacement member 43 through the deceleration mechanism 4. The at least one movable member 41 is disposed on the second rail 2, the guide member 42 is movably mounted on one side of the first rail 1, and one side of the guide member 42 is provided with a plurality of guide features 421 corresponding to the at least one movable member 41. A first groove 423 is formed in the guide member 42, and a second connecting portion 4231 protrudes from one end of the first groove 423. The two ends of the displacement member 43 are respectively mounted on the first connecting portion 13 and the second connecting portion 4231. The first rail 1 has a first joint 13 that is bent at one end. At least one movable member 41 abuts against the plurality of guide features 421, and the guide member 42 drives the displacement member 43 to compress and generate the thrust. This causes the second rail 2 to move relative to the first rail 1 in the first direction D1 and change from rapid displacement to deceleration displacement before the end of the stroke. This increases the service life of the stop elements or stops (not shown in the figure) on the first rail 1 and the second rail 2 when they abut against each other due to the force applied by the user, and also reduces the noise generated by the stop elements or stops on the first rail 1 and the second rail 2 colliding with each other during rapid displacement.
[0056] The slide rail assembly with a deceleration mechanism disclosed in this utility model comprises at least one movable member 41 as a damping gear, a guide member 42 as a rack, and a plurality of guide features 421 as teeth. One end of the first rail 1 is bent and extended with the first connecting portion 13. The at least one movable member 41 is disposed on the second rail 2. The guide member 42 is movably mounted on one side of the first rail 1. One side of the guide member 42 has a protrusion of the plurality of guide features 421 corresponding to the at least one movable member 41. A first groove 423 is formed within the guide member 42, and one end of the first groove 423 has a protrusion of the... The second set of connectors 4231, and the two ends of the displacement member 43 are respectively installed on the second set of connectors 4231 and the first set of connectors 13. By means that when the at least one movable member 41 engages with the plurality of guiding features 421 of the guide member 42, the guide member 42 moves synchronously in the first direction D1. The guide member 42 drives the displacement member 43 to compress, absorbing the impact force of the at least one movable member 41. This achieves the effect of the at least one movable member 41 abutting against the plurality of guiding features 421 of the guide member 42, thereby reducing the force of displacement impact and thus increasing service life.
