Abstract
Description
Technical Field
[0001] This utility model relates to a slide rail assembly, particularly a frame adapted to an industrial servo, which uses a gear mechanism to enable rapid displacement and deceleration displacement of one slide rail relative to another. Background Technology
[0002] In existing industrial server racks, the slide rail assembly moves its entire distance relative to another slide rail. This movement is stopped by stop components or integrated stop points mounted on each slide rail, which abut against each other. 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, generating 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

[0064] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0065] Example
[0066] Please see Figures 1 to 5As shown, this utility model is a slide rail assembly 1, comprising: a first rail 2 (e.g., an outer rail), a second rail 4 (e.g., an inner frame), a third rail 3 (e.g., a middle frame), and a gear mechanism 5. The first rail 2, the second rail 4, and the third rail 3 are longitudinally displaceable relative to each other. The third rail 3 extends the displacement stroke of the first rail 2 and the second rail 4. The gear mechanism 5 has a first rack 50 and a second rack 51 mounted on the longitudinal wall 41 of the second rail 4. Furthermore, the gear mechanism 5 has a first gear 522 disposed on one side 21 of the first rail 2 and disposed in at least one second frame groove 321. A second gear 532, a first rack 50 and a second rack 51 are parallel to and misaligned on the longitudinal wall 41, the first rack 50 has a plurality of first teeth 501, the second rack 51 has a plurality of second teeth 511, the third track 3 has a first end 31, a second end 32 relative to the first end 31, a first end face 33 located at the first end 31, a first frame groove 311 recessed from the first end face 33 toward the second end 32, and at least one second frame groove 321 recessed at the second end 32, the first gear 522 is located in the first frame groove 311.
[0067] Please see Figures 1 to 5 As shown, the gear mechanism 5 has at least one first damper 52 mounted on one side 21 of the first rail 2 and a second damper 53 mounted in at least one second frame groove 321 at the second end 32 of the third rail 3. The at least one first damper 52 has a first container 521 for containing damping material, such as a viscous liquid. The first container 521 is pivotally connected to a first gear 522, and the first gear 522 is connected to the first container 521 and can rotate. The damping material is used to allow the first gear 51 to rotate relative to the first container 521. The first damper 52 is formed by a certain amount of resistance and is mounted on one side 21 of the first rail 2. The second damper 53 has a second container 531 for accommodating another damping material, such as a viscous liquid substance. The second container 531 is pivotally connected to a second gear 532, which is connected to the second container 531 and can rotate. The other damping material provides another amount of resistance to the rotation of the second gear 532 relative to the second container 531, and together they form the second damper 53.
[0068] This utility model is described using a plurality of first dampers 52 as examples. The number of first dampers 52 may be three, four or five. The examples are not intended to limit the patent scope of this utility model.
[0069] Please refer to it again. Figure 3 , Figures 10 to 12As shown, the gear mechanism 5 further includes a plurality of first dampers 52, at least one first elastic element 54, and a plurality of first locking elements 55. Each of the first dampers 52 is provided with a plurality of clearance holes 523 on two opposite outer sides of the first container 521. The plurality of first locking elements 55 first pass through the plurality of clearance holes 523 and are then locked onto one side 21 of the first rail 2. At least one first elastic element 54 is installed at both ends between the plurality of first dampers 52. The plurality of first locking elements 55 are, for example, equal-height rivet elements, and the at least one first elastic element 54 is, for example, a compression spring.
[0070] This utility model is described in the example of two relief holes 523 extending from one end 5231 toward the other end 5232 to form a long groove. However, the two relief holes 523 extending from one end 5231 toward the other end 5232 may also extend into a trapezoidal shape, a teardrop shape, or other gradually expanding shapes. The example is not intended to limit the patent scope of this utility model.
[0071] Please refer to it again. Figure 13 and Figure 17 As shown, when the second rail 4 and the third rail 3 are at the first position P1 relative to the first rail 2, at least one first elastic element 54 is elastically compressed. During operation, the second rail 4 and the third rail 3 move synchronously towards the first direction D1 relative to the first rail 2. At this time, the first gear 522 is located in the first frame groove 311, and the first gear 522 meshes with a plurality of first teeth 501 in a first state S1. The meshing of the two generates a frictional force, or the damping material located in the first container 521 generates rotational resistance on the first gear, causing the second rail 4 and the third rail 3 to decelerate synchronously relative to the first rail 2. The first gear 522 disengages from the plurality of first teeth 501 and disengages from the first frame groove 311, which is a second state S2, causing the second rail 4 and the third rail 3 to change from deceleration displacement to rapid displacement synchronously relative to the first rail 2.
[0072] Please refer to the following first. Figures 14 to 16 As shown, when the first rack 50 is displaced in a first direction D1 by force, the first gear 522 of the plurality of first dampers 52 abuts against the plurality of first teeth 501 of the first rack 50, which drives the plurality of first dampers 52 to move synchronously in the first direction D1. The plurality of first locking fasteners 55, which pass through the plurality of clearance holes 523 of each first damper 52, abut against one end of the plurality of clearance holes 523 to form a limit. At this time, at least one first elastic member 54 installed between the plurality of first dampers 52 maintains elastic compression, causing the first gear 522 to align with the teeth of the plurality of first teeth 501 and mesh and rotate. When the first gear 522 disengages from the plurality of first teeth 501, at least one first elastic member 54 elastically extends, which in turn drives the plurality of first dampers 52 ( Figure 16The left side (52) is displaced in a second direction (D2) opposite to the first direction (D1), and is limited by a plurality of first locking fasteners (55) against one end (5231) of a plurality of clearance holes (523).
[0073] Please see Figures 18 to 22 As shown, when the second rail 4 and the third rail 3 move synchronously relative to the first rail 2 in the first direction D1 to the second position P2, the second rail 4 continues to move relative to the third rail 3 in the first direction D1. At this time, the second gear 532 is in a third state S3 when it aligns with a plurality of second teeth 511, causing the second rail 4 to move rapidly relative to the third rail 3. When the second gear 532 engages with a plurality of second teeth 511, it is in a fourth state S4. The engagement generates another frictional force or another damping material located in the second container 531 to provide rotational resistance for the second gear 522. At this time, the third state S3 switches to the fourth state S4, causing the second rail 4 to change from rapid displacement to decelerated displacement relative to the third rail 3 to the third position P3.
[0074] Please see Figure 13 , Figure 17 , Figure 18 , Figure 22 and Figure 23 As shown, when the second rail 4 is located at the third position P3 relative to the third rail 3, it moves in a second direction D2 that is opposite to the first direction D1. The second rail 4 and the third rail 3 move synchronously relative to the first rail 2 from the second position P2 to the first position P1. The direction of its movement towards the second direction D2 is opposite to the aforementioned description of the movement towards the first direction D1, and will not be repeated here.
[0075] Please refer to it again. Figures 6 to 9 As shown, in another embodiment of the present invention, apart from the gear mechanism 5 having a first rack 50 installed at the first end 31, the first rack 50 having a plurality of first teeth 501 extending horizontally toward the first frame groove 311 relative to the first frame groove 311, other cooperating components or structures are as described in the above paragraph and will not be repeated here.
[0076] The slide rail assembly 1 of this utility model is composed of a first rail 2, a second rail 4 and a third rail 3. Its structure and displacement, displacement in the first direction D1 and displacement in the opposite direction D2 are known technologies, and will not be described in detail here for the sake of simplicity.
[0077] In view of this, the slide rail assembly 1 disclosed in this utility model has a first gear 522 disposed on one side 21 of the first rail 2, and a second gear 532 disposed in at least one second frame groove 321, and a first rack 50 and a second rack 51 mounted parallel and misaligned on the longitudinal wall 41, or a first rack 50 mounted on the first end 31 of the third rail 3 and a second rack 51 mounted on the longitudinal wall 41 of the second rail 4. By means of the meshing of the gear and the rack, a frictional force is generated, or a damping material located in the container is used to provide gear rotation resistance, so that the second rail 4 and the third rail 3 relative to the first rail 2, before moving in the first direction and in the opposite direction to the second direction to the end of the stroke, change from rapid displacement to deceleration displacement, so as to increase the friction between the first rail 2, the second rail 4 and the first rail 2. The service life of the stop elements or stops (not shown in the figure) on the third rail 3, which are deformed by the force applied by the user when they come into contact with each other, helps to improve the smoothness of operation of the slide rail over a long period of time, and reduces the noise generated by the stop elements or stops on the first rail 2, the second rail 4 and the third rail 3 when they collide with each other during rapid displacement. In addition, each of the first dampers 52 has a plurality of clearance holes 523 on the two opposite outer sides of the first container 521 and at least one first elastic member 54 installed between each of the first dampers 52. This is used to increase the service life of the first gear 522 and the first tooth 501 when they mesh with each other due to the force applied by the user, which helps to improve the smoothness of operation of the first gear 522 meshing with the first tooth 501 over a long period of time.
