Description

Technical Field

[0001] This invention relates to a slide rail, and more particularly to a slide rail assembly with a damping device. Background Technology

[0002] US Patent Publication No. US8210623B2 discloses a damping device for a slide rail assembly, comprising a first rail member, a second rail member, a first bracket, a second bracket, a rack, and a damper. The second rail member is slidable relative to the first rail member. The first bracket and the second bracket are mounted and fixed to the first rail member. The rack is mounted on the first bracket, and the damper is mounted on the second bracket. The damper includes a container and a gear pivotally connected to the container, wherein the container contains damping material. When the second rail member displaces relative to the first rail member, the gear of the damper is driven by the rack, causing the gear to rotate and interact with the damping material in the container, thereby providing a fixed amount of resistance.

[0003] However, in order to meet the diverse needs of the market, it is sometimes undesirable to use a gear-like mechanism as described in the patent case to create resistance when the two rails are displaced relative to each other. Therefore, how to develop a different product has become an issue that cannot be ignored. Summary of the Invention

[0004] The purpose of this invention is to provide a slide rail assembly with a damping device.

[0005] According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, two working parts, a first damping device, and a second damping device. The first rail and the second rail are longitudinally displaceable relative to each other. The two working parts are arranged on the first rail at different longitudinal levels. The first damping device and the second damping device are arranged on the second rail. When the second rail displaces relative to the first rail from a first predetermined position in a first direction, a cushioning effect is provided through the interaction of one of the two working parts with the first damping device. When the second rail continues to displace relative to the first rail in the first direction, a cushioning effect is provided through the interaction of the other of the two working parts with the second damping device.

[0006] According to another aspect of the invention, a slide rail assembly includes a first rail, a second rail, two working parts, and a damping device. The second rail is longitudinally displaceable relative to the first rail; the two working parts are arranged on the first rail; the damping device is arranged on the second rail; wherein, when the second rail displaces relative to the first rail from a first predetermined position in a first direction, a cushioning effect is provided through the interaction of one of the two working parts with the damping device; wherein, when the second rail further displaces relative to the first rail in the first direction, a cushioning effect is provided through the interaction of the other of the two working parts with the damping device.

The second rail 24 and the first rail 22 are longitudinally displaceable relative to each other, and the second rail 24 can be in a first predetermined position P1 relative to the first rail 22 (e.g., an extended position, such as...). Figure 1 (As shown). In this embodiment, the X-axis is the longitudinal direction (or the length direction of the slide rail), the Y-axis is the transverse direction (or the side direction of the slide rail), and the Z-axis is the vertical direction (or the height direction of the slide rail).

[0032] Preferably, the first support portion 48a and the second support portion 48b of the base 46 correspond to the first wall 36a and the second wall 36b of the first rail 22 and can support each other respectively.

The second working piece 28 is located between the first working piece 26 and the third working piece 30.

[0035] Preferably, the first working piece 26 and the second working piece 28 are at different longitudinal levels. More specifically, the first working piece 26 and the third working piece 30 are at substantially the same first longitudinal level H1, and the second working piece 28 is at a second longitudinal level H2. The second longitudinal level H2 is different from the first longitudinal level H1, and the second longitudinal level H2 is substantially parallel to the first longitudinal level H1 (e.g., ...). Figure 3 (As shown).

[0036] Preferably, the first working piece 26 and the second working piece 28 are spaced apart by a predetermined distance X1, and the first working piece 26 and the third working piece 30 are spaced apart by another predetermined distance X2, which is greater than the predetermined distance X1 (e.g., ...). Figure 3 (As shown).

[0037] Preferably, the first working piece 26, the second working piece 28 and the third working piece 30 have substantially the same structural configuration. Here, it is taken that the first working piece 26, the second working piece 28 and the third working piece 30 are all spring pieces, but the implementation is not limited to this.

[0038] Preferably, the first rail 22 is provided with two or more mounting seats. For example, a first mounting seat 52, a second mounting seat 54, and a third mounting seat 56 are arranged (e.g., fixed to) the first rail 22. The first mounting seat 52, the second mounting seat 54, and the third mounting seat 56 can respectively mount the first working member 26, the second working member 28, and the third working member 30. The first mounting seat 52, the second mounting seat 54, and the third mounting seat 56 each have a first side L1 and a second side L2 facing each other, and at least one hole H connecting the first side L1 and the second side L2 (e.g., ...). Figure 4 (As shown).

[0039] Preferably, the first working member 26 includes a first connecting portion 58 and a first elastic portion 60 extending from the first connecting portion 58 (this part can also be referred to in conjunction with the above). Figure 4AThe first working member 26 has a first connecting portion 58 connected (e.g., fixed) to the first side L1 of the first mounting base 52. The first elastic portion 60 of the first working member 26 has at least one first protrusion 62, which can pass through at least one hole H from the first side L1 of the first mounting base 52 and extend out from the second side L2 of the first mounting base 52. The first protrusion 62 has a first blocking feature 64 and a first guiding structure 66 at two opposite positions (e.g., front and rear). The first blocking feature 64 is, for example, a wall, and the first guiding structure 66 is, for example, a slope or an arc surface (this part can also be referred to). Figure 4A However, its implementation is not limited.

[0040] Similarly, the second working member 28 includes a second connecting portion 68 and a second elastic portion 70 extending from the second connecting portion 68. The second connecting portion 68 of the second working member 28 is connected (e.g., fixed) to the first side L1 of the second mounting base 54, and the second elastic portion 70 of the second working member 28 has at least one second protrusion 72. The at least one second protrusion 72 can pass through the at least one hole H from the first side L1 of the second mounting base 54 and extend out from the second side L2 of the second mounting base 54. The second protrusion 72 has a second blocking feature 74 and a second guiding structure 76 at two opposite positions (e.g., front and rear). The second blocking feature 74 is, for example, a wall, and the second guiding structure 76 is, for example, a slope or an arc surface, but the implementation is not limited.

[0041] Similarly, the third working member 30 includes a third connecting portion 78 and a third elastic portion 80 extending from the third connecting portion 78. The third connecting portion 78 of the third working member 30 is connected (e.g., fixed) to the first side L1 of the third mounting base 56, and the third elastic portion 80 of the third working member 30 has at least one third protrusion 82. The at least one third protrusion 82 can pass through the at least one hole H from the first side L1 of the third mounting base 56 and extend out from the second side L2 of the third mounting base 56. The third protrusion 82 has a third blocking feature 84 and a third guiding structure 86 at two opposite positions (e.g., front and rear). The third blocking feature 84 is, for example, a wall, and the third guiding structure 86 is, for example, an inclined surface or an arc surface, but the implementation is not limited.

[0042] like Figure 5As shown, one of the first damping devices 32 and the second damping device 34 is adjacent to the first wall 42a of the second rail 24, and the other of the first damping device 32 and the second damping device 34 is adjacent to the second wall 42b of the second rail 24. Here, we take the example of the first damping device 32 being adjacent to the first wall 42a of the second rail 24 and the second damping device 34 being adjacent to the second wall 42b of the second rail 24, but the implementation is not limited to this.

[0043] Preferably, the slide rail assembly 20 further includes a first support frame 88 (also referred to as support frame), a first slider 90 (also referred to as slider), a first drive member 92 (also referred to as drive member) and a first elastic member 94 (also referred to as elastic member).

[0044] The first support frame 88 is arranged on the second rail 24. Taking the first support frame 88 connected (e.g., fixed) to the base 46 on the second rail 24 as an example, the first support frame 88, the base 46, and the second rail 24 can be considered as a single unit. The first support portion 48a of the first support frame 88 is adjacent to the base 46. The first support frame 88 is equipped with the first damping device 32 (also referred to as the damping device). The first support frame 88 includes a first path T1 (also referred to as the path), and the first slider 90 can slide along the first path T1. The first driving member 92 is movable relative to the second rail 24. Taking the first driving member 92 movably mounted to the first slider 90, and the second rail 24 including a first guiding feature 96 (also referred to as the guiding feature) arranged on the first support frame 88 as an example, the first guiding feature 96 is, for example, an inclined surface (e.g., Figure 7 (as shown) or an arc surface, but there are no limitations in its implementation.

[0045] Preferably, the first support frame 88 further includes a first space K1 (also referred to as space), and the first damping device 32 includes a first cylinder 98 (also referred to as cylinder) and a first rod 100 (also referred to as rod) that are telescopically compatible; the first cylinder 98 is installed in the first space K1, and a portion of the first rod 100 is located in the first path T1. The first path T1 is longitudinal, meaning that the direction of the first path T1 is the same as the length direction of the second rail 24.

[0046] Preferably, the first drive member 92 is pivotally connected to the first slider 90 via a first shaft 102.

[0047] Preferably, the first elastic member 94 connects a first connecting portion 104 of the base 46 to a first connecting feature 106 of the first slider 90.

[0049] Preferably, the base 46 includes a first stop 108, which can stop the first slider 90 at the first end E1 of the first path T1, thus having a limiting effect.

[0050] Preferably, the first slider 90 includes a pair of first wings 107 (due to the viewing angle, Figure 5 Only one first wing 107 is shown. The first wing 107 can be supported on a pair of first matching features 109 on the first path T1 to prevent the first slider 90 from disengaging from the first path T1 in the height direction (Z-axis direction) of the second track 24.

[0051] like Figure 6 As shown, Figure 6 Draw Figure 5 Another perspective (e.g., compared to) Figure 5 , Figure 6 (The first wall 42a and the second wall 42b of the second rail 24 are inverted). Furthermore, the slide rail assembly 20 preferably also includes a second support frame 110, a second slider 112, a second drive member 114, and a second elastic member 116.

[0052] The second support frame 110 is arranged on the second rail 24. For example, the second support frame 110 is connected (e.g., fixed) to the base 46 on the second rail 24, and the second support frame 110, the base 46, and the second rail 24 can be considered as a single unit. The second support portion 48b of the second support frame 110 is adjacent to the base 46. The second support frame 110 is equipped with the second damping device 34. The second support frame 110 includes a second path T2, and the second slider 112 can slide along the second path T2. The second driving member 114 is movable relative to the second rail 24. For example, the second driving member 114 is movably mounted to the second slider 112, and the second rail 24 includes a second guide feature 118 arranged on the second support frame 110. The second guide feature 118 is, for example, an inclined surface or an arc surface, but is not limited in implementation.

[0053] Preferably, the second support frame 110 further includes a second space K2, and the second damping device 34 includes a relatively telescopic second cylinder 120 and a second rod 122; the second cylinder 120 is installed in the second space K2, and a portion of the second rod 122 is located in the second path T2. The second path T2 is longitudinal, meaning that the direction of the second path T2 is the same as the length direction of the second rail 24.

[0054] Preferably, the second drive member 114 is pivotally connected to the second slider 112 via a second shaft 124.

[0055] Preferably, the second elastic member 116 connects a second connecting portion 126 of the base 46 to a second connecting feature 128 of the second slider 112.

[0056] Preferably, the second path T2 has a first end E1' and a second end E2' located opposite each other, the second cylinder 120 is adjacent to the second end E2' of the second path T2, and the second rod 122 extends into the second path T2 from the second end E2' of the second path T2.

[0057] Preferably, the base 46 includes a second stop 130, which can stop the second slider 112 at the first end E1' of the second path T2, thus having a limiting effect.

[0058] Preferably, the second slider 112 includes a pair of second wings 132 (due to the viewing angle, Figure 6 Only one second wing 132 is shown. The second wing 132 can be supported on a pair of second matching features 134 of the second path T2 to prevent the second slider 112 from disengaging from the second path T2 in the height direction (Z-axis direction) of the second rail 24.

[0059] like Figure 7 and Figure 8 As shown, the first cylinder 98 and the first rod 100 of the first damping device 32 are in a first state S1 relative to each other (e.g., an extended state or a buffer ready state). It is worth mentioning that the first cylinder 98 of the first damping device 32 is provided with a buffer medium and / or an elastic member (e.g., a spring). This part is within the technical scope that can be understood by those skilled in the art, and will not be described in detail here for the sake of simplicity.

[0060] like Figure 7 , Figure 8 and Figure 9 As shown, when the second track 24 is relative to the first track 22 from the first predetermined position P1 (e.g., Figure 7As shown, when the device moves in a first direction D1, the first damping device 32 interacts with one of the two working components (one of the first working component 26 and the second working component 28, taking the first working component 26 as an example) to provide a buffering effect (such as...). Figure 9 (As shown). The first direction D1 can be, for example, the closing direction, but is not limited in implementation.

[0061] Preferably, when the second rail 24 is displaced relative to the first rail 22 from the first predetermined position P1 toward the first direction D1, the first blocking feature 64 of the first working member 26 (the first protrusion 62) and the first driving member 92 come into contact with each other to form a pushing relationship (e.g., Figure 8 and Figure 9 As shown), so that the first working piece 26 moves from a first initial position M1 (also referred to as the initial position, as shown) via the first driving member 92 according to the first slider 90. Figure 8 (As shown) The displacement of the first path T1 along the first support frame 88 relative to the second rail 24 can interact with the first damping device 32 (e.g. Figure 9 As shown), the first rod 100 of the first damping device 32 is switched from the first state S1 to a second state S2 (e.g., a retracted state, such as...) relative to the first cylinder 98. Figure 9 As shown), it is used to provide a cushioning effect. At this time, the first elastic element 94 is in a state of accumulating an elastic force J.

[0062] like Figure 10 , Figure 11 and Figure 12 As shown, during the process of the second rail 24 continuing to displace relative to the first rail 22 in the first direction D1, the first guiding feature 96 can guide the first driving member 92 to pivot at an angle to a first derailment position M2 (also referred to as the derailment position, such as...). Figure 10 As shown), the first working member 26 (the first blocking feature 64 of the first protrusion 62) and the first driving member 92 are no longer in contact, thereby relieving the interaction between the first working member 26 and the first damping device 32, and causing the first damping device 32 to stop providing a buffering effect. On the other hand, the first damping device 32 can still be restored from the second state S2 to the first state S1 (as shown) through the buffer medium and / or elastic member in the first cylinder 98. Figure 12 As shown in the figure, this part is a technical scope that can be understood by those familiar with the field, and will not be elaborated on here for the sake of brevity.

[0063] Preferably, during the process of the first damping device 32 returning from the second state S2 to the first state S1, the first damping device 32 can be used through the first slider 90 to drive the first driving member 92 from the first disengaged position M2 (e.g., ...). Figure 10(As shown) Return to the first initial position M1 (as shown) Figure 12 (As shown).

[0064] Preferably, the first driving member 92 releases the elastic force J in response to the first elastic member 94 (e.g., Figure 10 (As shown) This helps to increase the speed at which the first drive member 92 returns from the first deactivated position M2 to the first initial position M1, and also helps the first damping device 32 recover from the second state S2 to the first state S1 more quickly.

[0065] like Figure 10 and Figure 11 As shown, the second damping device 34 has substantially the same structural configuration as the first damping device 32. The second cylinder 120 and the second rod 122 of the second damping device 34 are in a first state S1' (e.g., an extended state or a buffer ready state) relative to each other.

[0066] like Figure 10 , Figure 11 and Figure 12 As shown, when the second rail 24 continues to displace relative to the first rail 22 in the first direction D1, the interaction between the other of the two working components (the other of the first working component 26 and the second working component 28, taking the second working component 28 as an example) and the second damping device 34 provides a buffering effect (such as...). Figure 12 (As shown).

[0067] Preferably, when the second rail 24 continues to displace relative to the first rail 22 in the first direction D1, the second working member 28 (the second blocking feature 74 of the second protrusion 72) and the second driving member 114 come into contact with each other to form a pushing relationship (e.g., Figure 10 and Figure 11 As shown), so that the second working piece 28 moves from a second initial position M1' via the second drive member 114 according to the second slider 112 (as shown). Figure 11 As shown, the displacement of the second path T2 along the second support frame 110 relative to the second rail 24 can interact with the second damping device 34 (e.g., Figure 12 As shown), the second rod 122 of the second damping device 34 is switched from the first state S1' to a second state S2' (e.g., a retracted state, such as...) relative to the second cylinder 120. Figure 12 As shown), it is used to provide a cushioning effect. At this time, the second elastic element 116 is in a state of accumulating an elastic force J'.

[0068] like Figure 13 and Figure 14As shown, when the second rail 24 continues to displace relative to the first rail 22 in the first direction D1, the second guiding feature 118 can guide the second driving member 114 to pivot at an angle to a second deactivation position M2' (e.g., Figure 13 As shown), the second working member 28 (the second blocking feature 74 of the second protrusion 72) and the second driving member 114 are no longer in contact, thereby releasing the interaction between the second working member 28 and the second damping device 34, and causing the second damping device 34 to stop providing a buffering effect. On the other hand, the second damping device 34 can still recover from the second state S2' to the first state S1' through the buffer medium and / or elastic member in the second cylinder 120 (as shown). Figure 14 As shown in the figure, this part is a technical scope that can be understood by those familiar with the field, and will not be elaborated on here for the sake of brevity.

[0069] Preferably, during the process of the second damping device 34 returning from the second state S2' to the first state S1', the second damping device 34 can be used through the second slider 112 to drive the second drive member 114 from the second deactivated position M2' (e.g., ...). Figure 13 (As shown) Return to the second initial position M1' (as shown) Figure 14 (As shown).

[0070] Preferably, the second driving member 114 releases the elastic force J' in response to the second elastic member 116 (e.g., Figure 13 (As shown) This helps to increase the speed at which the second drive member 114 returns from the second deactivated position M2' to the second initial position M1', and also helps the second damping device 34 recover from the second state S2' to the first state S1' more quickly.

[0071] As described above, the first working piece 26 and the second working piece 28 can be respectively paired with the first damping device 32 and the second damping device 34 to provide a buffering effect during the displacement of the second rail 24 relative to the first rail 22 from the first predetermined position P1 to the first direction D1. For example, it has at least two stages of buffering effect.

[0072] Alternatively, the first working member 26 and the third working member 30 can be used in conjunction with the first damping device 32 to ensure that the second rail 24 also has a buffering effect during its displacement relative to the first rail 22 from the first predetermined position P1 to the first direction D1. For example, it has at least two stages of buffering effect.

[0073] Specifically, when the second rail 24 displaces relative to the first rail 22 from the first predetermined position P1 in the first direction D1, a buffering effect is provided through the interaction between one of the two working components (one of the first working component 26 and the third working component 30, taking the first working component 26 as an example) and the first damping device 32. This part has already been disclosed above. Figure 7 , Figure 8 and Figure 9 The details of its embodiments and related descriptions will not be repeated here.

[0074] like Figure 13 and Figure 14 As shown, the first cylinder 98 and the first rod 100 of the first damping device 32 are in the first state S1 (e.g., an extended state or a buffer preparation state) relative to each other. When the second rail 24 is further displaced in the first direction D1 relative to the first rail 22, a buffering effect is provided through the interaction between the other of the two working parts (the first working part 26 and the other of the third working part 30, taking the third working part 30 as an example) and the first damping device 32.

[0075] Better, such as Figure 13 , Figure 14 and Figure 15 As shown, when the second rail 24 is further displaced relative to the first rail 22 in the first direction D1, the second blocking feature 84 of the second protrusion 82 of the third working member 30 comes into contact with the first driving member 92 to form a pushing relationship (e.g., Figure 14 and Figure 15 As shown), so that the third working piece 30 moves from the first initial position M1 (as shown) via the first driving member 92 according to the first slider 90. Figure 14 (As shown) The displacement of the first path T1 along the first support frame 88 relative to the second rail 24 can interact with the first damping device 32 (e.g. Figure 15 As shown), the first rod 100 of the first damping device 32 is switched from the first state S1 to the second state S2 (e.g., a retracted state, such as...) relative to the first cylinder 98. Figure 15 As shown), it is used to provide a cushioning effect. At this time, the first elastic element 94 is in the state of accumulating the elastic force J.

[0076] like Figure 16 and Figure 17 As shown, when the second rail 24 moves further relative to the first rail 22 in the first direction D1, the first guiding feature 96 can guide the first driving member 92 to pivot at an angle to the first deactivation position M2 (e.g., Figure 16As shown), the second blocking feature 84 of the second protrusion 82 of the third working member 30 is no longer in contact with the first driving member 92, thereby releasing the interaction between the third working member 30 and the first damping device 32, and causing the first damping device 32 to stop providing a buffering effect (such as...). Figure 16 (As shown). On the other hand, the first damping device 32 can be released from the second state S2 (as shown) through the buffer medium and / or elastic member in the first cylinder 98. Figure 16 As shown) Restored to the first state S1 (as shown) Figure 17 As shown in the figure, this part is a technical scope that can be understood by those familiar with the field, and will not be elaborated on here for the sake of brevity.

[0077] Preferably, during the process of the first damping device 32 returning from the second state S2 to the first state S1, the first damping device 32 can be used through the first slider 90 to drive the first driving member 92 from the first disengaged position M2 (e.g., ...). Figure 16 (As shown) Return to the first initial position M1 (as shown) Figure 17 (As shown).

[0078] Preferably, the first driving member 92 releases the elastic force J in response to the first elastic member 94 (e.g., Figure 16 (As shown) This helps to increase the speed at which the first drive member 92 returns from the first deactivated position M2 to the first initial position M1, and also helps the first damping device 32 recover from the second state S2 to the first state S1 more quickly.

[0079] like Figure 18 As shown, the second rail 24 is in a second predetermined position P2 (e.g., a folded position) relative to the first rail 22, wherein the base 46 supports at least a portion of the rear 22b of the adjacent first rail 22.

[0080] When the second rail 24 moves relative to the first rail 22 from the second predetermined position P2 to the first predetermined position P1 in a second direction D2, the first damping device 32 and the second damping device 34 will not provide a buffering effect.

[0081] For example, when the second rail 24 is at the second predetermined position P2 relative to the first rail 22, since the first driving member 92 corresponds to the first guide structure 66 of the first protrusion 62 of the first working member 26 (the first guide structure 66 of the first protrusion 62) and the third guide structure 86 of the third protrusion 82 of the third working member 30 (which are at the same longitudinal level), and the second driving member 114 corresponds to the second guide structure 76 of the second protrusion 72 of the second working member 28, therefore, when the second rail 24 moves relative to the first rail 22 from the second predetermined position P2 to the first predetermined position P1, the first driving member... The first drive member 92 can pass over the third working member 30 and the first working member 26 (that is, when the first drive member 92 passes over the third guide structure 86 of the third protrusion 82 of the third working member 30 and the first guide structure 66 of the first protrusion 62 of the first working member 26, there will be no or insufficient interference), and the second drive member 114 can pass over the second working member 28 (that is, when the second drive member 114 passes over the second guide structure 76 of the second protrusion 72 of the second working member 28, there will be no or insufficient interference), so that the first damping device 32 and the second damping device 34 will not provide a buffering effect. The first direction D1 and the second direction D2 are opposite directions; for example, the second direction D2 is the opening direction.

[0082] Based on the above description, it can be seen that the enhanced efficacy and advantages of the present invention lie in the following: through the first working member 26 and the second working member 28 respectively paired with the first damping device 32 and the second damping device 34, or through the first working member 26 and the third working member 30 paired with the first damping device 32, the second rail 24, relative to the first rail 22, moves from one predetermined position to another predetermined position with two or more (continuous) buffering effects. Therefore, it can be seen that the first rail 22 is provided with a plurality of working members, which can be paired with at least one damping device on the second rail 24, allowing the second rail 24 to have a full-stroke buffering effect during the movement of the second rail 24 relative to the first rail 22 from one predetermined position to another predetermined position.

[0083] Although the present invention has been described with reference to specific embodiments, those skilled in the art should recognize that the above embodiments are merely illustrative of the invention, and various equivalent changes and modifications can be made without departing from the spirit of the invention. Therefore, any changes or modifications to the above embodiments within the scope of the essential spirit of the invention will fall within the scope of the claims of this application.
