Technical Field

[0001] The invention relates to a slide rail, in particular to a slide rail mechanism capable of reducing friction force when the slide rail is displaced. Background Art

[0002] For example, U.S. Patent Publication No. US 8,147,011B2 discloses a slide rail assembly, which includes a first rail member, a second rail member and a third rail member. The second rail member is movably mounted between the first rail member and the second rail member. The second rail member includes a first rail section and a second rail section connected back to back to each other. The second rail section is configured with a plurality of first rollers and a second roller; when the third rail member is pulled out relative to the second rail member, the first roller and the second roller help and are used to support the third rail member. Alternatively, when the third rail member is pulled out to a predetermined stroke relative to the second rail member, the support wheels connected to the front support of the first rail member can also be used to support the third rail member. This case mainly discloses that when the third rail member is pulled out and separated from the second rail member and is to be reassembled again, the pair of support wheels of the front bracket are used to provide the third rail member with easy guidance for reassembly with the second rail member, and to assist the sliding of the third rail member.

[0024] like Figures 1 to 3 As shown, a slide rail mechanism according to an embodiment of the present invention comprises a first support member 22, a slide rail assembly 24 and at least one rolling member. A first longitudinal length M1 of the slide rail assembly 24 is different from a second longitudinal length M2 of the first support member 22. For example, the first longitudinal length M1 of the slide rail assembly 24 is smaller than the second longitudinal length M2 of the first support member 22 (e.g. Figure 1 As shown), further, the slide rail assembly 24 includes a first rail 26, and the longitudinal length of the first rail 26 is less than the longitudinal length of the first support member 22; or, the slide rail mechanism further includes a second support member 34 connected to the first support member 22, and the longitudinal length of the first rail 26 is less than the longitudinal length of the second support member 34. The first rail 26 and the first support member 22 can be longitudinally displaced relative to each other. Here, the X-axis direction is the longitudinal direction (or the length direction or displacement direction of the slide rail), the Y-axis direction is the transverse direction (or the lateral direction of the slide rail), and the Z-axis direction is the vertical direction (or the height direction of the slide rail). The second support member 34 is, for example, a bracket, and the second support member 34 can be used to provide the first support member 22 and the slide rail assembly 24 to be installed on a rack.

[0025] The number of the at least one rolling element can be one or more. Here, a first rolling element 25a (such as a front rolling element) and a second rolling element 25b (such as a rear rolling element) are taken as an example, but the implementation is not limited. The rolling elements 25a and 25b are used to provide the first rail 26 and the first support element 22 with longitudinal displacement relative to each other.

[0026] Preferably, the rolling elements 25a, 25b are arranged on one of the first rail 26 and the first support element 22. Here, the first rolling element 25a and the second rolling element 25b are arranged on the first rail 26, and the first rolling element 25a and the second rolling element 25b have a predetermined longitudinal distance between each other. Further, the first rolling element 25a and the second rolling element 25b are pivotally connected to a first mounting element 29a and a second mounting element 29b through a first shaft 27a and a second shaft 27b, respectively, wherein the mounting elements 29a, 29b are connected (e.g., fixedly connected) to the first rail 26 and can be regarded as a part of the first rail 26.

[0027] Preferably, the slide rail mechanism further includes a slide rail device 32, and the slide rail device 32 includes the first support member 22 and the second support member 34 connected to the first support member 22 (for example, fixedly connected), and the first support member 22 and the second support member 34 can be regarded as a whole; or, the first support member 22 and the second support member 34 can be integrated together, and the implementation is not limited. Among them, the first rail 26 and the rolling members 25a and 25b can be displaced together. Further, the first rail 26 can be displaced along the longitudinal length direction of the first support member 22 through the rolling members 25a and 25b, which helps to reduce the friction or push-pull force when the first rail 26 is displaced relative to the first support member 22. In other words, it helps to improve the smoothness of the displacement of the first rail 26.

[0028] Preferably, the rolling elements 25a, 25b are components having an arc-shaped profile, such as rollers or balls, but the implementation is not limited thereto.

[0029] The slide rail assembly 24 further includes a second rail 28 and a third rail 30, wherein the first rail 26 is an outer rail, the second rail 28 is a middle rail, and the third rail 30 is an inner rail. For example, the second rail 28 is movably mounted between the first rail 26 and the third rail 30.

[0030] Preferably, the second support member 34 includes a release feature 36 , and the release feature 36 is taken as a space here as an example; the second support member 34 further includes a blocking feature 37 adjacent to the release feature 36 , and the blocking feature 37 is, for example, a wall, but the implementation is not limited thereto.

[0031] Preferably, the first support member 22 is further provided with a stopper 38 . For example, the first support member 22 is provided with a bracket 40 . The bracket 40 is adjacent to an end (eg, the front) of the first support member 22 , and the bracket 40 is provided with the stopper 38 .

[0032] Preferably, the first support member 22 of the rail device 32 further comprises a support channel for accommodating a plurality of movable rails, such as a first movable rail 42 and a second movable rail 44, wherein the first movable rail 42 is located between the first support member 22 and the second movable rail 44. The longitudinal length of the third rail 30 of the rail assembly 24 is smaller than the second movable rail 44 of the rail device 32. It is worth mentioning that the third rail 30 of the slide rail assembly 24 can be used to carry a first load (not shown), and the second movable rail 44 of the slide rail device 32 can be used to carry a second load (not shown); when the second load is removed from the second movable rail 44, or when the second movable rail 44 (and the second load) are removed from the first movable rail 42, the slide rail assembly 24 can be displaced along the longitudinal length direction of the first support member 22 (or the second support member 34) of the slide rail device 32 through the rolling members 25a, 25b on the first rail 26, which helps to reduce the friction force when the first rail 26 (or the slide rail assembly 24) is displaced relative to the first support member 22 (or the slide rail device 32), which has a labor-saving effect for the user to operate the first rail 26 (or the slide rail assembly 24).

[0033] Preferably, the slide rail assembly 24 further includes a first auxiliary member 46 and a second auxiliary member 48 . The first auxiliary member 46 is arranged on the first rail 26 , and the second auxiliary member 48 is arranged on the second rail 28 .

[0034] Preferably, one of the first auxiliary member 46 and the second auxiliary member 48 is movable, and the other of the first auxiliary member 46 and the second auxiliary member 48 is fixed. For example, the first auxiliary member 46 is pivotally connected to the first rail 26 through a shaft 50, so that the first auxiliary member 46 can pivot relative to the first rail 26, and the second auxiliary member 48 is fixed to the second rail 28.

[0035] Preferably, the slide rail assembly 24 further includes an auxiliary rail 52 arranged to the first rail 26, and the first rail 26 is movably mounted on one of the first support member 22 and the second support member 34 through the auxiliary rail 52. Further, the auxiliary rail 52 includes a first auxiliary wall 54a, a second auxiliary wall 54b, and an intermediate wall 56 connected between the first auxiliary wall 54a and the second auxiliary wall 54b, and the intermediate wall 56 is connected (for example, fixedly connected) to a first side L1 (for example, L2) of the first rail 26. Figure 3As shown), for example, the back side, the first auxiliary wall 54a and the second auxiliary wall 54b are used to hold one of the first support member 22 and the second support member 34, for example, the first auxiliary wall 54a and the second auxiliary wall 54b can respectively hold a first wall 57a (for example, an upper wall) and a second wall 57b (for example, a lower wall) of the first support member 22, but the implementation is not limited; on the other hand, the second rail 28 can be movably mounted on a first channel (such as a second channel 26) on a second side L2 of the first rail 26 Figure 3 As shown), the second side L2 is opposite to the first side L1; in addition, the third rail 30 is movably mounted on a second channel of the second rail 28.

[0036] Preferably, the slide rail assembly 24 further includes a working piece 58 movably mounted on the second rail 28, and the third rail 30 is provided with a corresponding feature 60 for use with the working piece 58 (eg, Figure 3 As shown), the third rail 30 and the second rail 28 are abutted against the working piece 58 through the corresponding feature 60, so that they can be displaced synchronously.

[0037] Preferably, the working member 58 is pivotally connected to the second rail 28 via a connecting member 62 .

[0038] Preferably, the first rail 26 is provided with a retaining member 64, wherein the retaining member 64 is, for example, an elastic member (e.g., a spring), but the implementation is not limited thereto; the retaining member 64 includes a release structure 66 and a blocking structure 68 adjacent to the release structure 66. The release structure 66 is, for example, an inclined surface or an arc surface, and the blocking structure 68 is a wall (vertical wall), but the implementation is not limited thereto; in other alternative implementations, the release structure 66 and / or the blocking structure 68 can be directly integrated into the first rail 26.

[0039] like Figure 4 and Figure 5 As shown, the slide rail assembly 24 is in a retracted state relative to the first support member 22 (the second support member 34 or the slide rail device 32). When the second rail 28 is moved relative to the first support member 22 and / or the second support member 34 from a first predetermined position P1 (e.g., a retracted position, such as Figure 4 During the longitudinal displacement of the second rail 28 and the first rail 26 toward a first predetermined direction D1 (eg, an opening direction), the second rail 28 and the first rail 26 are in a synchronous displacement relationship (eg, Figure 5As shown in FIG. 1 , the third rail 30 is installed in the second channel of the second rail 28, and the third rail 30 and the second rail 28 can abut against the working member 58 through the corresponding feature 60. Therefore, when the third rail 30 moves toward the first predetermined direction D1 relative to the first support member 22, the third rail 30 and the second rail 28 can move synchronously, and the second rail 28 and the first rail 26 can also move synchronously. At this time, it can be considered that the third rail 30, the second rail 28 and the first rail 26 move toward the first predetermined direction D1 together. The first rail 26 contacts the first wall 57a of the first support member 22 through the rolling members 25a and 25b. For example, the first rail 26 can roll in the first predetermined direction D1 along the longitudinal length direction of the first wall 57a (for example, the upper wall) of the first support member 22 through the rolling members 25a and 25b, which helps to reduce the friction force of the first rail 26 when it is displaced relative to the first support member 22. The first wall 57a (for example, the upper wall) of the first support member 22 can provide the supporting effect of the rolling members 25a and 25b, which helps to improve the supporting strength of the first rail 26 (or the slide rail assembly 24). Preferably, the first rail 26 holds the first wall 57a (and the second wall 57) of the first support member 22 through the first auxiliary wall 54a (and the second auxiliary wall 54b) of the auxiliary rail 52, which helps to stabilize or reliability the first rail 26 when it is displaced relative to the first support member 22.

[0040] Preferably, when the second rail 28 moves from the first predetermined position P1 to the first predetermined direction D1, the second rail 28 and the first rail 26 have the synchronous displacement relationship (such as Figure 5 shown).

[0041] Preferably, the first auxiliary member 46 responds to an elastic force accumulated by an elastic member 70 and / or the first auxiliary member 46 is supported by the second support member 34, and the first auxiliary member 46 can be maintained in a first state S1 and can contact the second auxiliary member 48 (such as Figure 5 For example, the second auxiliary member 48 includes at least one contact portion 72 (eg, a hook portion or a hook-shaped structure, such as Figure 4 ), and the at least one contact portion 72 can be used to contact a corresponding portion 69 (such as Figure 5 As shown), the second rail 28 and the first rail 26 have the synchronous displacement relationship when they move toward the first predetermined direction D1.

[0042] Preferably, the elastic member 70 is arranged on the first side L1 of the first rail 26 so that the elastic member 70 can be hidden between the first support member 22 (or the slide rail device 32) and the first rail 26, wherein the elastic member 70 is, for example, a spring, but is not limited in implementation, and the elastic member 70 has at least one elastic portion 71 that applies elastic force to at least one extension portion 73 of the first auxiliary member 46, and supports the first auxiliary member 46 through the second support member 34 to keep the first auxiliary member 46 in the first state S1 (such as Figure 5 shown).

[0043] like Figure 6 As shown, when the second rail 28 and the first rail 26 are synchronously displaced to a second predetermined position P2 in the first predetermined direction D1 relative to the first support member 22 and / or the second support member 34, the release feature 36 of the second support member 34 is used to release the synchronous displacement relationship between the second rail 28 and the first rail 26.

[0044] Preferably, when the first rail 26 is in the second predetermined position P2, the release feature 36 of the second support member 34 can provide the elastic member 70 with the release of the elastic force, and the first auxiliary member 46 moves from the above-mentioned first state S1 (for example, pivots in a predetermined pivot direction R) to a second state S2 in response to the elastic force, so that the first auxiliary member 46 (the corresponding portion 69) no longer contacts the second auxiliary member 48 (at least one contact portion 72), for example, the second auxiliary member 48 (at least one contact portion 72) and the first auxiliary member 46 (the corresponding portion 69) are laterally offset from each other to release the synchronous displacement relationship between the second rail 28 and the first rail 26.

[0045] Preferably, when the first auxiliary member 46 is in the second state S2, the blocking feature 37 of the second support member 34 can block the first auxiliary member 46 to prevent the first rail 26 from shifting from the second predetermined position P2 to a second predetermined direction D2 (e.g., a folding direction) opposite to the first predetermined direction D1; and the blocking portion 38 of the first support member 22 (the bracket 40) can block one of the first rail 26 and the auxiliary rail 52 to prevent the first rail 26 from shifting from the second predetermined position P2 to the first predetermined direction D1. For example, the blocking portion 38 of the first support member 22 (the bracket 40) can block the first rail 26 (the first mounting member 29a), but the implementation is not limited thereto.

[0046] like Figure 7 and Figure 8 As shown (as Figures 7 to 13The at least one rolling element 25a, 25b is omitted from illustration. The slide rail assembly 24 further includes at least one first slide-assisting device 74 movably mounted between the second rail 28 and the first rail 26 to help the second rail 28 move smoothly relative to the first rail 26; and a second slide-assisting device 76 movably mounted between the second rail 28 and the third rail 30 to help the third rail 30 move smoothly relative to the second rail 28. For example, the first slide-assisting device 74 includes a plurality of first slide-assisting members 78, and the second slide-assisting device 76 includes a plurality of second slide-assisting members 80, which are, for example, balls or rollers or the like.

[0047] Specifically, the corresponding feature 60 of the third rail 30 and the working piece 58 of the second rail 28 have a predetermined longitudinal distance (eg, Figure 7 shown), Figure 1 When the first rail 26 is at the second predetermined position P2, the third rail 30 and the second rail 28 can continue to move toward the first predetermined direction D1. Figure 7 The state shown is that the third rail 30 and the second rail 28 are too tight (or the friction is too large) to each other and produce a similar synchronous relationship. Preferably, when the third rail 30 moves in the first predetermined direction D1, the third rail 30 and the second rail 28 are set in a synchronous displacement relationship. For example, when the third rail 30 moves in the first predetermined direction D1, through the mutual contact between the corresponding feature 60 and the working piece 58, the third rail 30 can synchronously drive the second rail 28 (such as Figure 8 shown).

[0048] Preferably, the third rail 30 has a first wall 82a and a second wall 82b, and the first wall 82a of the third rail 30 has the corresponding feature 60, and the corresponding feature 60 is, for example, a hole wall of a hole H; the first wall 82a of the third rail 30 can temporarily support the workpiece 58, so that the workpiece 58 is in an initial state K1 (such as Figure 7 When the third rail 30 moves toward the first predetermined direction D1, the hole H of the third rail 30 corresponds to a synchronization feature 84 of the working member 58, so that the working member 58 can move (for example, pivot) from the initial state K1 to a predetermined state K2 (for example, Figure 8 As shown), the corresponding feature 60 of the third rail 30 can contact the synchronous feature 84 of the workpiece 58, so that the third rail 30 can synchronously drive the second rail 28 (as shown in FIG. 1 ) in the first predetermined direction D1. Figure 8 shown).

[0049] Preferably, the second rail 28 includes a through hole 88 through which a working portion 90 of the working piece 58 can pass toward the first rail 26, and the working portion 90 of the working piece 58 is used in conjunction with the retaining member 64 (release structure 66 and blocking structure 68) of the first rail 26 (such as Figure 8 shown).

[0050] like Figure 8 and Fig. 9 As shown, when the third rail 30 and the second rail 28 are synchronously displaced toward the first predetermined direction D1 (as shown in FIG. Figure 8 The release structure 66 of the first rail 26 is used to release the synchronous displacement relationship between the third rail 30 and the second rail 28 (as shown in FIG. Fig. 9 For example, the working portion 90 of the working member 58 on the second rail 28 can be guided by the release structure 66 of the first rail 26, so that the working member 58 moves (e.g., pivots) to a predetermined angle and is no longer in the predetermined state K2, so that the corresponding feature 60 of the third rail 30 is no longer in contact with the synchronization feature 84 of the working member 58 (e.g., Fig. 9 ), for releasing the synchronous displacement relationship between the third rail 30 and the second rail 28, so that the third rail 30 and the second rail 28 can be individually displaced relative to the first rail 26 at the second predetermined position P2 toward the first predetermined direction D1. The elastic member 86 is in a state of accumulating an elastic force.

[0051] like Fig.10 As shown, when the second rail 28 further moves toward the first predetermined direction D1 to a third predetermined position P3, the blocking structure 68 of the first rail 26 can block the second rail 28 to prevent the second rail 28 from moving from the third predetermined position P3 to the second predetermined direction D2. For example, when the second rail 28 is at the third predetermined position P3, the elastic object 86 releases the elastic force to the working piece 58, so that the working portion 90 of the working piece 58 can be blocked by the blocking structure 68 of the first rail 26.

[0052] Preferably, the first rail 26 is further arranged with a first limiting feature 92, and the second rail 28 is further arranged with a second limiting feature 94; when the second rail 28 is in the third predetermined position P3, the front and rear ends of the first sliding aid device 74 are respectively in contact between the first limiting feature 92 and the second limiting feature 94, thereby preventing the second rail 28 from shifting from the third predetermined position P3 to the first predetermined direction D1.

[0053] like Fig.11As shown, the third rail 30 is relatively located at the third predetermined position P3 and continues to move toward the first predetermined direction D1 to a fourth predetermined position P4. At this time, the slide rail assembly 24 is in an extended state relative to the first support member 22 (the second support member 34 or the slide rail device 32), for example, a fully extended state. Preferably, when the third rail 30 is at the fourth predetermined position P4, the second slide assisting device 76 is located at an end (for example, a front end) adjacent to the second rail 28.

[0054] like Fig.12 and Fig.13 As shown, when the third rail 30 moves from the fourth predetermined position P4 to the second predetermined direction D2 (as shown in FIG. Fig.12 As shown), the third rail 30 is used to release the blocking relationship of the blocking structure 68 to the second rail 28 (as shown Fig.13 Further, a portion of the third rail 30, such as a rear end r, may contact the synchronization feature 84 of the workpiece 58 (such as Fig.12 ), to drive the working member 58 so that the working portion 90 of the working member 58 is no longer blocked by the blocking structure 68 of the first rail 26 (as shown in FIG. Fig.13 ), for allowing the second rail 28 to move from the third predetermined position P3 to the second predetermined direction D2.

[0055] like Fig.14 and Fig.15 As shown, one of the second rail 28 and the first auxiliary member 46 includes a first guide feature 96. Preferably, the other of the second rail 28 and the first auxiliary member 46 includes a second guide feature 98. The first guide feature 96 and the second guide feature 98 are, for example, an inclined surface or an arc surface, but the implementation is not limited thereto. Here, the first guide feature 96 is arranged on the second rail 28 (the second auxiliary member 48). This part can be referred to in conjunction with Figure 3 ), and the second guide feature 98 is arranged on the first auxiliary part 46 as an example.

[0056] When the second rail 28 moves from the third predetermined position P3 to the second predetermined direction D2, the second rail 28 is used to release the blocking relationship of the blocking feature 37 to the first rail 26. For example, the first guide feature 96 of the second rail 28 can contact the second guide feature 98 of the first auxiliary member 46, thereby the first auxiliary member 46 can be moved from the second state S2 (such as Fig.14 As shown) driven to the first state S1 (as shown Fig.15As shown in the figure, the blocking feature 37 of the second support member 34 no longer blocks the first auxiliary member 46 of the first rail 26, so as to allow the first rail 26 (and the auxiliary rail 52) to move from the second predetermined position P2 to the second predetermined direction D2, and the third rail 30, the second rail 28 and the first rail 26 (and the auxiliary rail 52) can continue to move in the second predetermined direction D2 until the slide rail assembly 24 returns to the above-mentioned folded state (this part can cooperate with Figure 4 ). Among them, through the rolling elements 25a, 25b (due to the viewing angle, Fig.14 and Fig.15 Only the mounting members 29a and 29b are shown to indicate the positions of the rolling members 25a and 25b, and can roll in the second predetermined direction D2 along the longitudinal length direction of the first wall 57a (for example, the upper wall) of the first support member 22, which helps to reduce the friction force when the first rail 26 is displaced relative to the first support member 22, wherein the first wall 57a (for example, the upper wall) of the first support member 22 can provide the rolling members 25a and 25b with a support effect, which helps to enhance the support strength of the first rail 26 (or the slide rail assembly 24).

[0057] It is worth mentioning that the slide rail assembly 24 can be applied to the above-mentioned rack, wherein the third rail 30 can be used to carry the above-mentioned first load (such as electronic equipment or drawers). When the slide rail assembly 24 is in the folded state, if the user first pulls out the third rail 30 (first load) and the second rail 28 in the first predetermined direction D1 (synchronously), and at this time the first rail 26 is still folded relative to the first support member 22 (the second support member 34 or the slide rail device 32), for the first rail 26, the pulled out third rail 30 (the first load) and the second rail 28 may generate a torque due to a weight (such as the weight of the first load), causing the friction between the first rail 26 and the first support member 22 (or the second support member 34) to increase. Therefore, if the first rail 26 is to be pulled out, the user needs to spend more effort to pull the first rail 26 relative to the first support member 22 (or the second support member 34) in the first predetermined direction D1. The first rail 26 provided in the embodiment of the present invention can roll in the first predetermined direction D1 along the longitudinal length direction of the first wall 57a (for example, the upper wall) of the first support member 22 through the rolling members 25a and 25b, which helps to reduce the friction force when the first rail 26 is displaced relative to the first support member 22, and / or the second rail 28 and the first rail 26 can be displaced in the first predetermined direction D1 synchronously, thereby avoiding the above-mentioned problems.

[0058] like Fig.16As shown, the first rolling member 25a and the first support member 22 have mutually matching features. Further, one of the first rolling member 25a and the first support member 22 includes a first matching feature 100, and the other of the first rolling member 25a and the first support member 22 includes a second matching feature 102. Here, the first rolling member 25a includes the first matching feature 100, and the first support member 22 includes the second matching feature 102 as an example.

[0059] Specifically, the first matching feature 100 is a wheel groove, and the second matching feature 102 is a longitudinal protrusion that can provide the wheel groove contact, thereby improving the stability or reliability of the rolling element 25a when rolling along the longitudinal length direction of the first wall 57a of the first support element 22.

[0060] It can be seen that the slide rail mechanism provided by the embodiment of the present invention has the following features:

[0061] 1. The first rail 26 of the slide rail assembly 24 is provided with at least one rolling element 25a (eg, a roller) to reduce the friction force when the first rail 26 is displaced relative to the first support element 22 (or the slide rail device 32).

[0062] 2. The second rail 28 (e.g., middle rail) and the first rail 26 (e.g., outer rail) can be synchronously displaced in the first predetermined direction D1 relative to the first support member 22 (the second support member 34), and / or the third rail 30 (inner rail) and the second rail 28 (middle rail) can be synchronously displaced in the first predetermined direction D1.

[0063] 3. The at least one rolling element 25a (25b) and the first support element 22 have a first matching feature 100 and a second matching feature 102 that match each other, which can enhance the stability or reliability of the at least one rolling element 25a (25b) when rolling along the longitudinal length direction of the first support element 22.

[0064] Although the present invention has been described with reference to the current specific embodiments, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and various equivalent changes and modifications may be made without departing from the spirit of the present invention. Therefore, any changes and modifications to the above embodiments within the spirit of the present invention will fall within the scope of the claims of this application.
