Description

[Technical field]

[0001] The present invention relates to a drive mechanism according to the preamble of claim 1 . [Background technology]

[0002] US Patent Application Publication No. 2023 / 0049413A1 discloses a tray module suitable for a chassis. The chassis includes at least two side plates. Each side plate has a track member. The track member includes a first horizontal section, an inclined section, and a second horizontal section. The inclined section is connected to the first horizontal section and the second horizontal section and is located between the first horizontal section and the second horizontal section. The first horizontal section, the inclined section, and the second horizontal section cooperate to form a substantially S-shaped structure. The tray module includes a carrier body, at least two first connecting rods, and at least two second connecting rods. Each first connecting rod has a movable end and a driven end. The movable end of each first connecting rod is pivotally connected to the carrier body and slidably disposed within the corresponding track member. Each second connecting rod has a pivot end, an operating end, and a pivot connection located between the pivot end and the operating end. The pivot end of each second connecting rod is pivotally connected to a corresponding side plate. The driven end of each first connecting rod is pivotally connected to the pivot connection of the corresponding second connecting rod. When a user operates the handle to pull the second connecting rod upward, the first connecting rod is driven to move along an S-shaped path formed by the first horizontal section, the inclined section and the second horizontal section of the track member such that the tray module switches from the receiving state to the lifting state along a non-linear or non-vertical path.

[0003] However, to meet various demands, it has become a significant challenge to provide alternative solutions that facilitate easy installation and removal of tray modules. [Prior art documents] [Patent documents]

[0024] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part of the invention and which illustrate specific embodiments in which the invention may be practiced. In this regard, directional terms such as "upper", "lower", "left", "right", "front", "rear" and the like are used with respect to the orientation of the view(s) being described. The members of the invention can be positioned in many different orientations. As such, the directional terms are used for purposes of illustration and are in no way limiting. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not limiting. Also, unless specified, the term "connected" is intended to mean either an indirect or direct mechanical connection. Thus, when a first device is connected to a second device, the connection may be via a direct mechanical connection or via an indirect mechanical connection via other devices and connections.

[0025] As shown in FIG. 1 and FIG. 2, the drive mechanism 20 includes a first casing 22, a second casing 24, and at least one operating member. Preferably, in this embodiment, as an example, the at least one operating member includes a first operating member 26 and a second operating member 28, which are substantially symmetrical with respect to each other. As shown in FIG. 2, in this embodiment, as an example, it should be noted that the longitudinal direction is defined by the length direction of the first casing 22 or the second casing 24 and can be parallel to the X-axis. The transverse direction is defined by the lateral or width direction of the first casing 22 or the second casing 24 and can be parallel to the Y-axis. The vertical direction is defined by the height direction of the first casing 22 or the second casing 24 and can be parallel to the Z-axis.

[0026] The second casing 24 is disposed on the first casing 22. As shown in FIG 1, in this embodiment, as an example, the second casing 24 is disposed above the support portion 30 of the first casing 22.

[0027] The first operating member 26 and the second operating member 28 are movably attached to one of the first casing 22 and the second casing 24, and the other of the first casing 22 and the second casing 24 moves in response to the movement of the first operating member 26 and the second operating member 28. In this embodiment, as an example, the first operating member 26 and the second operating member 28 are movably attached to the first casing 22. When the first operating member 26 and the second operating member 28 are moved from the first state S1 shown in FIG. 1 to the second state S2 shown in FIG. 2, the first operating member 26 and the second operating member 28 drive the second casing 24 to move relative to the first casing 22 from the first predetermined position P1 shown in FIG. 1 to the second predetermined position P2 shown in FIG. 2 along the first vertical direction D1, for example, the upward direction. When the first operating member 26 and the second operating member 28 move from the second state S2 shown in FIG. 2 to the first state S1 shown in FIG. 1, the second casing 24 moves relative to the first casing 22 along a second vertical direction D2, for example, a downward direction, which can be opposite to the first vertical direction D1, from the second predetermined position P2 shown in FIG. 2 to the first predetermined position P1 shown in FIG. 1.

[0028] Preferably, the first casing 22 includes a first wall 32 and a second wall 34. A first space K1 of the first casing 22 is defined between the first wall 32 and the second wall 34 and is configured to accommodate the second casing 24.

[0031] Preferably, the first casing 22 further includes a first side wall 36 and a second side wall 38. As shown in FIG. 1, in this embodiment, as an example, the first side wall 36 and the second side wall 38 are the left side wall and the right side wall of the first casing 22, respectively, and the first height H1 of the first side wall 36 is smaller than the second height H2 of the second side wall 38. However, the present invention is not limited to this embodiment. The above-mentioned configuration of the first casing 22 can expose the second casing 24 to provide lateral access to the second casing 24 housed in the first casing 22, so that a user can detach or unload at least one object from the second space K2 of the second casing 24 or easily place at least one object in the second space K2 of the second casing 24.

[0032] Preferably, the support portion 30 of the first casing 22 may be the bottom portion of the first casing 22 , for example, the bottom surface of the first casing 22 .

[0033] Preferably, a plurality of attachment mechanisms are disposed on each of the first side wall 36 and the second side wall 38 of the first casing 22 to facilitate attachment of the drive mechanism 20. In this embodiment, by way of example, the plurality of attachment mechanisms may include at least a first attachment mechanism 40a and a second attachment mechanism 40b.

[0034] Preferably, the structural configuration of the first operating member 26, the first casing 22 and the second casing 24 can be substantially symmetrical to the structural configuration of the second operating member 28, the first casing 22 and the second casing 24. The working principle of the first operating member 26 is substantially the same as the working principle of the second operating member 28. A detailed description of the structural configuration of the first operating member 26 and the first wall 32 of the first casing 22 and the working principle of the first operating member 26 is as follows, and a detailed description of the structural configuration of the second operating member 28 and the second wall 34 of the first casing 22 and the working principle of the second operating member 28 is omitted here for brevity.

[0035] 3 to 5, the shaft member 42 is disposed on one of the first wall 32 of the first casing 22 and the first operating member 26, and the long hole 44 is disposed on the other of the first wall 32 of the first casing 22 and the first operating member 26 to allow the shaft member 42 to pass through. As shown in FIG. 5, in this embodiment, for example, the long hole 44 is disposed in the first operating member 26, and the shaft member 42 is connected to the first wall 32 of the first casing 22, for example, fixedly connected thereto, and passes through a part of the long hole 44 disposed in the first operating member 26.

[0036] Preferably, as shown in Figures 3 and 5, the first operating member 26 includes an engagement mechanism 46, and a first corresponding mechanism 48 and a second corresponding mechanism 50 are disposed on the first wall 32 of the first casing 22. The engagement mechanism 46 is configured to selectively engage with the first corresponding mechanism 48 or the second corresponding mechanism 50. As shown in Figures 4 and 5, in this embodiment, by way of example, the engagement mechanism 46 can be a notch or a C-shaped slot formed on the wall of the first operating member 26, and the first corresponding mechanism 48 and the second corresponding mechanism 50 can be two protrusions. However, the present invention is not limited to this embodiment.

[0037] Preferably, the second casing 24 includes a first predetermined wall 52 and a second predetermined wall 54. As shown in FIG. 1 and FIG. 2, in this embodiment, the first predetermined wall 52 and the second predetermined wall 54 of the second casing 24 can be, for example, the front wall and the rear wall of the second casing 24, respectively. Furthermore, the driving member 56 is disposed on one of the first operating member 26 and the second casing 24, for example, the first predetermined wall 52 of the second casing 24, and the predetermined hole 58 is disposed on the other of the first operating member 26 and the second casing 24, for example, the first predetermined wall 52 of the second casing 24, to allow the driving member 56 to pass through. The predetermined hole 58 has a predetermined length. When the first operating member 26 is in the first state S1, the length direction of the predetermined hole 58 is substantially parallel to the length direction of the long hole 44. Specifically, the driving member 56 can be a protrusion or a pin that passes through a part of the predetermined hole 58. In this embodiment, for example, the predetermined hole 58 is disposed in the second casing 24, for example, in the first predetermined wall 52 of the second casing 24, and the drive member 56 is disposed in the first operating member 26 and passes through a portion of the predetermined hole 58. However, the present invention is not limited to this embodiment.

[0038] Preferably, the first operating member 26 further includes an operating portion 60. The operating portion 60 and the engagement mechanism 46 are located adjacent to two opposite ends of the first operating member 26, respectively. In the present embodiment, for example, the operating portion 60 and the engagement mechanism 46 are located adjacent to the first end E1 and the second end E2 of the first operating member 26, respectively. In addition, the first operating member 26 further includes an extension portion 62 connected between the first end E1 and the second end E2 of the first operating member 26, and the long hole 44 and the driving member 56 are disposed in the extension portion 62.

[0039] Preferably, as shown in FIGS. 5 and 6, the drive mechanism 20 further includes an elastic member 64 configured to apply an elastic force F to the first operating member 26.

[0040] Preferably, as shown in Figures 3, 5 and 6, the elastic member 64 includes a first elastic portion 66 and at least one second elastic portion 68. As shown in Figures 3 and 6, the first elastic portion 66 is hooked to a predetermined mechanism 70 of the first operating member 26. As shown in Figure 5, the second elastic portion 68 is connected to the first casing 22. As shown in Figure 5, in this embodiment, as an example, the second elastic portion 68 is connected to the shaft member 42 on the first wall 32 of the first casing 22. However, the present invention is not limited to this embodiment.

[0041] Preferably, at least one shock absorber 72 is disposed in one of the first casing 22 and the second casing 24. In this embodiment, by way of example, the at least one shock absorber 72 is disposed in the first wall 32 of the first casing 22 and can be an elastic or flexible object. However, the present invention is not limited to this embodiment. For example, in other embodiments, the shock absorber 72 can be a hydraulic support rod assembly or a recoil spring support rod assembly.

[0042] As shown in Figures 3-6, the drive member 56 of the first operating member 26 is configured to pass through a portion of a predetermined hole 58 in the second casing 24. As shown in Figures 5 and 6, when the first operating member 26 is in the first state S1 and located at the first position S1a, the engagement mechanism 46 and the first corresponding mechanism 48 engage with each other to prevent the first operating member 26 from moving away from the first state S1.

[0043] Preferably, as shown in Figures 5 and 6, the first operating member 26 in the first state S1 is held in the first position S1a in response to an elastic force F provided by the elastic member 64 and acting on the second end E2 of the first operating member 26 to keep the engagement mechanism 46 engaged with the first corresponding mechanism 48, and the second casing 24 is locked in the first predetermined position P1 relative to the first casing 22.

[0044] As shown in Fig. 7, when the second casing 24 is locked in a first predetermined position P1 relative to the first casing 22 by the first operating member 26 in the first state S1 and first position S1a, the first operating member 26 and the first wall 32 of the first casing 22 extend substantially parallel in the transverse direction, i.e., the lateral direction, or parallel along the Y axis. When the first operating member 26 in the first state S1 is moved from the first position S1a shown in Fig. 7 to the second position S1b shown in Fig. 8, the engagement mechanism 46 and the first corresponding mechanism 48 are disengaged from each other to allow the first operating member 26 to move from the first state S1 to the second state S2 along the first predetermined direction R1.

[0045] As shown in FIGS. 7-9, the first operating member 26 in the first state S1 can be moved from a first position S1a to a second position S1b by operating the operating portion 60 of the operating member 26 with a first force F1 to disengage the engagement mechanism 46 from the first corresponding mechanism 48. Thereafter, the first operating member 26 can be moved from the first state S1 to the second state S2 along a first predetermined direction R1 by operating the operating portion 60 of the operating member 26 with a second force F2. In this embodiment, the first operating member 26 is configured to rotate 90 degrees to move from the first state S1 to the second state S2. However, the present invention is not limited to this embodiment.

[0046] When the first operating member 26 is moved from the first state S1 to the second state S2, the first operating member 26 drives the second casing 24 to move linearly along the first vertical direction D1 relative to the first casing 22 from a first predetermined position P1 shown in FIG. 8, through an intermediate position shown in FIG. 9, to a second predetermined position P2 shown in FIG. 10.

[0047] 10 and 11, after the first operating member 26 is moved from the first state S1 to the second state S2, the first operating member 26 in the second state S2 can be moved from the fourth position S2b to the third position S2a along the second vertical direction D2 in response to the elastic force F of the elastic member 64 and / or gravity to engage the engagement mechanism 46 with the second corresponding mechanism 50 so as to prevent the first operating member 26 from moving away from the second state S2. Thus, the second casing 24 moves from the second predetermined position P2 to a third predetermined position P3 slightly lower than the second predetermined position P2 so as to be locked at the third predetermined position P3 relative to the first casing 22, in order to allow a user to pull out or remove at least one object from the second space K2 of the second casing 24 or to easily place at least one object in the second space K2 of the second casing 24.

[0048] As shown in Figures 11 and 12, the first operating member 26 in the second state S2 can be moved from the third position S2a to the fourth position S2b along the first vertical direction D1 by operating the operating portion 60 of the operating member 26 with a third force F3 to disengage the engagement mechanism 46 from the second corresponding mechanism 50. When the first operating member 26 in the second state S2 is moved from the third position S2a to the fourth position S2b along the first vertical direction D1, the first operating member 26 drives the second casing 24 to move linearly along the first vertical direction D1 from the third predetermined position P3 to the second predetermined position P2 relative to the first casing 22. Thereafter, the first operating member 26 can be moved from the second state S2 to the first state S1 along a second predetermined direction R2 opposite to the first predetermined direction R1 by operating the operating portion 60 of the operating member 26 with a fourth force F4. When the first operating member 26 is moved from the second state S2 to the first state S1, the first operating member 26 drives the second casing 24 to move linearly along the second vertical direction D2 from the second predetermined position P2 to the first predetermined position P1 relative to the first casing 22. After the first operating member 26 is moved from the second state S2 to the first state S1, the first operating member 26 in the first state S1 can be moved from the second position S1b to the first position S1a in response to the elastic force F provided by the elastic member 64 to cause the engagement mechanism 46 to engage with the first corresponding mechanism 48 to prevent the first operating member 26 from moving away from the first state S1 to lock the second casing 24 in the first predetermined position P1 relative to the first casing 22.

[0049] Preferably, as shown in FIG. 7, when the second casing 24 moves along the second vertical direction D2 from the second predetermined position P2 to the first predetermined position P1, at least one shock absorber 72 on the first casing 22 is configured to contact the second casing 24 to provide a shock absorbing or noise reducing effect.

[0050] As shown in FIGS. 13 and 14, the drive mechanism 20 is fitted to at least one slide rail assembly 74. In this embodiment, the at least one slide rail assembly 74 includes two slide rail assemblies 74 that are substantially symmetrical to each other. Specifically, each of the two slide rail assemblies 74 includes a first rail 76 and a second rail 78 that is displaceable relative to the first rail 76. Preferably, each of the two slide rail assemblies 74 further includes a third rail 80 that is movably mounted between the first rail 76 and the second rail 78. The first rail 76 is fixedly mounted to an object, for example, a cabinet or a rack. Each of the first side wall 36 and the second side wall 38 of the first casing 22 is attached to the corresponding second rail 78 by a corresponding first mounting mechanism 40a and a corresponding second mounting mechanism 40b.

[0051] As shown in FIG. 13, when the second casing 24 is positioned at a first predetermined position P1 relative to the first casing 22, at least one object 82 on the second casing 24, such as an electronic device or a hard disk drive, is blocked by a corresponding second rail 78 along a transverse direction, such as the transverse direction T, so that the at least one object 82 cannot be pulled away or removed from the second space K2 of the second casing 24 along the transverse direction T. As shown in FIG. 14, when the second casing 24 moves from a first predetermined position P1 to a second predetermined position P2 relative to the first casing 22 by operating the first operating member 26 and / or the second operating member 28, the second casing 24 is configured to move at least one placed object 82 above the corresponding second rail 78 having a predetermined height h so that the at least one placed object 82 on the second casing 24 is not blocked by the corresponding second rail 14 along the lateral direction T to enable a user to pull or remove the at least one placed object 82 from the second space K2 of the second casing 24 along the lateral direction T. It should be noted that when the second casing 24 moves from the second predetermined position P2 to the third predetermined position P3 relative to the first casing 22, the at least one object 82 is still above the corresponding second rail 78 having a predetermined height h to enable a user to pull or remove the at least one object 82 away from or from the second space K2 of the second casing 24 along the lateral direction T.

[0052] Of course, in other embodiments, the drive mechanism may include only the first operating member and the second operating member may be omitted.

[0053] From the above, the present invention has the following features:

[0054] 1. In contrast to conventional tray modules configured to move non-linearly along a non-linear or non-vertical path, in the present invention, when at least one operating member, e.g., the first operating member 26 and / or the second operating member 28, is moved from the first state S1 to the second state S2, the at least one operating member is configured to drive the second casing 24 to move linearly from a first predetermined position P1 to a second predetermined position P2 relative to the first casing 22 to meet specific requirements.

[0055] 2. When at least one operating member, e.g., the first operating member 26 and / or the second operating member 28, is in the first state S1, in response to the elastic force F provided by the elastic member 64, the engagement mechanism 46 and the first corresponding mechanism 48 are engaged with each other to prevent the at least one operating member from moving away from the first state S1 to lock the second casing 24 in the first predetermined position P1. When at least one operating member, e.g., the first operating member 26 and / or the second operating member 28, is in the second state S2, in response to the elastic force F provided by the elastic member 64, the engagement mechanism 46 and the second corresponding mechanism 50 are engaged with each other to prevent the at least one operating member from moving away from the second state S2 to lock the second casing 24 in the third predetermined position P3. The present invention can prevent unintended movement of the second casing 24, and therefore the present invention is safe and reliable.

[0056] 3. When the second casing 24 moves linearly from the first predetermined position P1 to the second predetermined position P2 or the third predetermined position P3 relative to the first casing 22, the second casing 24 is configured to move at least one placed object 82 above a corresponding second rail 78 having a predetermined height h to facilitate a user to pull or remove the at least one placed object 82 from the second space K2 of the second casing 24 along the lateral direction T.

[0057] 4. When the second casing 24 moves from the second predetermined position P2 to the first predetermined position P1, at least one shock absorber 72 on the first casing 22 is configured to contact the second casing 24 to provide a shock absorbing effect or a noise reducing effect.

[0058] Those skilled in the art will readily appreciate that numerous modifications and variations of the apparatus and method are possible while retaining the teachings of this invention.
