Boosting module

Abstract

A push-pull module suitable for assisting the insertion and removal of a first component and a second component comprises a first base, an elastic member, a second base and a linkage assembly. The first base has a storage space and is used to carry the first component. One end of the elastic member is fixedly disposed on the first base, and the other end has a convex portion. The second base displaceably accommodates the storage space and is used to carry the second component. The linkage assembly comprises a handle, a connecting rod and a cam. When the handle rotates in a first direction, the handle drives the cam to push against the convex portion through the connecting rod, so that the cam rotates over the convex portion and generates a force toward the first base on the second base. When the handle rotates in a second direction, the handle drives the cam to support the convex portion through the connecting rod, and the convex portion generates a force to push the second base away from the first base through the cam.

Description

[Technical field]

[0002] The present invention relates to a structure for assisting the disassembly and assembly of components, and in particular to a push-pull module with a labor-saving effect. [Background technology]

[0004] Electronic devices, such as servers, are usually equipped with various circuit boards or electronic components to complete various operations. As the performance of electronic devices increases, the number of pins used to connect the circuit boards increases. In addition, in order to make the volume of the circuit boards or electronic components meet the requirements, the pin density on the circuit boards or electronic components is also increasing. As a result, the disassembly of the circuit boards and electronic components will become more and more laborious and difficult, so there is room for improvement. [Summary of the invention]

[0006] The technical problem to be solved by the present invention is to provide a push-pull module with labor-saving effect.

[0007] In order to solve the above technical problems, the present invention provides a push-pull module, which is suitable for assisting the insertion and removal of the first component and the second component. The push-pull module includes a first base, an elastic member, a second base and a linkage assembly. The first base has a storage space and is used to carry the first component. One end of the elastic member is fixedly arranged on the first base, and the other end has a convex portion. The second base is displaceably accommodated in the storage space and is used to carry the second component. The linkage assembly is arranged at a position where the second base faces the first base and includes a handle, a connecting rod and a cam. The handle is pivoted to the second base and can pivot in the first direction and the second direction. One end of the connecting rod is pivoted to the handle. The cam is pivoted to the second base and the other end of the connecting rod. When the handle rotates in the first direction, the handle drives the cam to push against the convex portion through the connecting rod, so that the cam rotates over the convex portion and generates a force toward the first base on the second base. When the handle rotates in the second direction, the handle drives the cam to support the convex portion through the connecting rod, and the convex portion generates a force to push the second base away from the first base through the cam.

[0008] Compared with the prior art, the push-pull module of the present invention sets a linkage assembly between the first base supporting the first component and the second base supporting the second component, so that the handle of the linkage assembly drives the cam to push against the convex part through the connecting rod, so that the cam rotates over the convex part and generates a force on the second base toward the first base; when the handle rotates along the second direction, the handle drives the cam to be supported on the convex part through the connecting rod, and the convex part generates a force to push the second base away from the first base through the cam; the user only needs to rotate the handle to generate the force for downward assembly or upward pulling out, thereby achieving the purpose of labor saving.

[0025] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of an embodiment of the booster module of this case; Figure 2 This is a partial structural exploded diagram of one embodiment of the booster module of this case; Figure 3 This is a schematic diagram of a state where the first base 10 and the second base 30 of one embodiment of the booster-pull module of this case are separated; Figure 4 for Figure 3 The partial enlarged view of the circled portion 4. The push-pull module is suitable for assisting the plugging and unplugging of the first component P1 and the second component P2 to achieve the purpose of labor saving.

[0026] See also Figures 1 to 3 The push-pull module includes a first base 10, an elastic member 20, a second base 30 and a linkage assembly 40. The first component P1 and the elastic member 20 are disposed on the first base 10, and the second component P2 and the linkage assembly 40 are disposed on the second base 30. The linkage assembly 40 acts on the elastic member 20 and drives the second base 30 to assist the disassembly between the first component P1 and the second component P2, and can achieve a labor-saving effect.

[0027] See also Figures 1 to 3 In some embodiments, the first base 10 carries the first component P1 and is detachably mounted on a cabinet (not shown); the second base 30 carries the second component P2 and is connected to the first component P1 on the first base 10. In some embodiments, the first base 10 and the second base 30 may be components of a tray, a chassis, or a computer module including other electronic components, respectively, and the first component P1 may be a motherboard fixed to the chassis, and the second component P2 may be a display adapter, a memory, or other circuit board connected to the motherboard, but the present invention is not limited thereto.

[0028] See also Figures 1 to 3 In some embodiments, the first base 10 is a tray structure with a cross-section of a shape of a U and has a first bottom plate 11 and two first side plates 12 and a first opening relative to the first bottom plate 11, and each first side plate 12 is respectively placed on opposite sides of the first bottom plate 11. In one embodiment, each first side plate 12 is perpendicular to the first bottom plate 11, but the present invention is not limited thereto. Here, a storage space S for accommodating the first component P1, the second base 30, and the second component P2 is formed between the first bottom plate 11 and each first side plate 12. In addition, the first base 10 is defined as a first inner side on the side where the two first side plates 12 face each other, and the opposite side is defined as a first outer side, that is, the first bottom plate 11 and each first side plate 12 perpendicular to the first bottom plate 11 and the first opening surround the first inner side together. In this embodiment, the first component P1 can be fixedly disposed on the first bottom plate 11 of the first base 10 and located on the first inner side of the first base 10, but the present invention is not limited thereto. In some embodiments, the first component P1 may also be disposed on the two first side panels 12 by means of a snap fastener, a clamp or other means, and is located on the first inner side of the first base 10 .

[0029] See also Figures 1 to 3 In some embodiments, the elastic member 20 is a long sheet made of a material with elastic restoring force (such as metal, plastic, etc.). In one embodiment, the elastic member 20 is a metal sheet and has a first end 21 and a second end 22 opposite to each other. The first end 21 of the elastic member 20 is fixedly disposed on the first side plate 12 of the first base 10 and is located on the first inner side of the first base 10. The second end 22 of the elastic member 20 is spaced apart from the first side plate 12 and is not attached to the first side plate 12. In this way, the second end 22 of the elastic member 20 can be elastically displaced relative to the first side plate 12 from the first inner side of the first base 10 toward the first outer side of the first base 10.

[0030] See also Figures 1 to 3 In some embodiments, the elastic member 20 is integrally formed as a whole, and the elastic member 20 can also be composed of multiple plates or components, and the elastic member 20 is a long flat plate whose first end 21 and the second end 22 are roughly coplanar, and the first side plate 12 of the first base 10 has at least two plane plates that are stepped and not coplanar. The two plane plates are integrally formed to form the first side plate 12, and the plane plates can also be connected through a connecting folding plate by welding. In this embodiment, the position of the first end 21 fixed to one of the plane plates of the first side plate 12 and the position of the second end 22 relative to the other plane plate of the first side plate 12 are two non-coplanar plane plates, whereby when the first end 21 of the elastic member 20 is set on the first side plate 12 of the first base 10 and is not elastically deformed, the second end 22 has a spacing that can be elastically displaced relative to the first side plate 12.

[0031] See also Figure 5 , Figure 5 Another embodiment in which the elastic member 20 can be elastically displaced relative to the first side plate 12 is shown. In this embodiment, the first side plate 12 is a single plane plate and has a break 121. The elastic member 20 is also located at the first inner side of the first base 10, and the first end 21 of the elastic member 20 is fixed to the first side plate 12, and the second end 22 corresponds to the position of the break 121. In this way, when the elastic member 20 is pushed, the second end 22 of the elastic member 20 can be displaced toward the first outer side through the break 121, thereby realizing the elastic displacement of the elastic member 20.

[0032] In some embodiments, see Figure 3 and Figure 6The second end 22 of the elastic member 20 has a convex portion 221, and the convex portion 221 has an upper surface 2211 and a lower surface 2212. The top of the upper surface 2211 is flush with the second end 22 and is farther away from the first bottom plate 11 of the first base 10 than the lower surface 2212. The upper surface 2211 is a plane roughly parallel to the first bottom plate 11, and the lower surface 2212 is an arc-shaped surface, but the present invention is not limited thereto. In other embodiments, the upper surface 2211 of the convex portion 221 may also be a U-shaped or V-shaped groove with an opening facing upward, and the lower surface 2212 may also be an inclined surface. In this embodiment, the lower surface 2212 is generally a U-shaped surface with symmetrical arc surfaces on both sides, but the present invention is not limited thereto.

[0033] In some embodiments, see Figures 1 to 3 , the second base 30 is a tray structure with a cross section of a ㄩ shape and has a second bottom plate 31 and two second side plates 32 and a second opening relative to the second bottom plate 31, and each second side plate 32 is respectively placed on opposite sides of the second bottom plate 31. In one embodiment, each second side plate 32 is roughly perpendicular to the second bottom plate 31, but the present invention is not limited thereto. Here, the second base 30 is defined as the second inner side on the side of the second side plates 32 facing each other, and the second outer side on the other side, that is, the second bottom plate 31 and each second side plate 32 perpendicular to the second bottom plate 31 and the second opening surround the second inner side together. In this embodiment, the second component P2 can be fixedly arranged on the second bottom plate 31 of the second base 30 and located on the second outer side of the second base 30, whereby, when the second base 30 is accommodated in the first inner side of the first base 10, the second component P2 on the second base 30 can be connected to the first component P1 on the first base 10, but the present invention is not limited thereto.

[0034] In some embodiments, the second component P2 may also be fixedly disposed on the second bottom plate 31 of the second base 30 and located at the second inner side of the second base 30, or fixedly disposed on the second side plates 32 and located at the second inner side of the second base 30, and the second bottom plate 31 has a break for the connector of the second component P2 to pass through the break of the second bottom plate 31 and connect to the first component P1. In this way, when the second base 30 is accommodated in the first inner side of the first base 10, the second component P2 on the second base 30 can be connected to the first component P1 on the first base 10.

[0035] See also Figures 1 to 6 In some embodiments, the linkage assembly 40 includes a handle 41, a connecting rod 42, and a cam 43. The handle 41 is a roughly U-shaped structure, and both ends of the handle 41 are respectively pivotally connected to the second side plates 32 of the second base 30 by a handle shaft 411, so that the handle 41 can be pivoted on the second base 30 along the first direction D1 or the second direction D2, and can be held by the user to drive the second base 30 to move. Here, the handle 41 is pivotally connected to the outer side of the second base 30.

[0036] See also Figures 1 to 6 The connecting rod 42 is a long strip structure, and one end of the connecting rod 42 is pivotally connected to the corresponding end of the handle 41 by a first rotation axis 421 different from the corresponding handle axis 411. Here, the position where the connecting rod 42 is pivotally connected to the handle 41 is not the same as the position where the handle 41 is pivotally connected to the second base 30, so that when the handle 41 pivots, it can drive the connecting rod 42 and link with the connecting rod 42.

[0037] See also Figures 1 to 6 The cam 43 is pivoted to the second rotating shaft 422 at the other end of the connecting rod 42 and is pivoted to the second side plate 32 of the second base 30 by the cam shaft 431. The cam 43 is located outside the second base 30. Here, the position where the cam 43 is pivoted to the second side plate 32 is not coaxial with the position where the cam 43 is pivoted to the connecting rod 42, so that the cam 43 and the connecting rod 42 are linked. In this embodiment, after the cam 43 is pivoted to the second base 30, it can be pivoted synchronously with the handle 41 along the first direction D1 or the second direction D2. In addition, the position where the connecting rod 42 is pivoted to the handle 41 and the cam 43 is at the same height. Specifically, the virtual line of the center of the first rotating shaft 421 and the second rotating shaft 422 of the connecting rod 42 is parallel to the second bottom plate 31, and the vertical heights of the two ends of the connecting rod 42 from the second bottom plate 31 are the same after being pivoted to the second base 30.

[0038] See also Figure 3 and Figure 4 In some embodiments, the outer contour of the cam 43 at least includes a first section 432, a second section 433, a third section 434, and a fourth section 435 connected in sequence. Here, the first section 432 and the third section 434 are parallel straight sections with a curvature of 0, and the second section 433 and the fourth section 435 are arcs with curvatures. In terms of appearance, the second section 433 is an arc convex compared to the cam shaft 431, and the fourth section 435 is an arc concave compared to the cam shaft 431. Specifically, the center of curvature of the second section 433 is located within the outer contour range of the cam 43, and the center of curvature of the fourth section 435 is located outside the outer contour range of the cam 43.

[0039] In some embodiments, the second section 433 and the fourth section 435 are not limited to having only a single curvature. Here, the second section 433 is composed of two arcs with different curvatures, and the fourth section 435 is composed of an arc with a curvature and a straight section with a curvature of 0 to form a U-shaped arc, but the present case is not limited to this.

[0040] See also Figure 3 and Figure 4In some embodiments, the outer contour of the cam 43 further includes a fifth section 436, a sixth section 437, and a seventh section 438 sequentially connected between the first section 432 and the fourth section 435, the fifth section 436 is connected to the fourth section 435, and the seventh section 438 is connected to the first section 432. Here, the camshaft 431 is located within the range surrounded by the outer contour of the cam 43.

[0041] See also Figure 3 and Figure 4 , the fifth section 436 and the seventh section 438 are arcs with curvatures, the sixth section 437 is a straight section with a curvature of 0, and the fifth section 436 is an arc that is convex compared to the cam shaft 431. In this way, from the appearance of the cam 43, the fourth section 435 and the third section 434 will form a notch between the second section 433 and the fifth section 436. In addition, the extension direction of the seventh section 438 is perpendicular to the extension direction of the first section 432.

[0042] The above is the main structural configuration of one embodiment of the push-pull module of this case, and its operation will be described below with reference to the drawings.

[0043] See also Figure 3 When the second base 30 is not assembled to the first base 10, the handle 41 is usually in an upright state in order to facilitate the user to hold the handle 41 to drive the second base 30. Here, the upright state of the handle 41 refers to a state in which the handle 41 is upright and protrudes from the second base 30. In this state, the first rotation axis 421 of the connecting rod 42 is located on the side of the handle axis 411 close to the cam 43, and the second rotation axis 422 of the connecting rod 42 is located on the side of the cam axis 431 away from the handle 41.

[0044] See also Figure 6 When the first component P1 and the second component P2 are to be combined, the second base 30 is first placed into the first inner side of the first base 10 in a direction in which the second side plate 32 is relative to the first side plate 12 of the first base 10. When the second base 30 is at least partially placed into the first inner side of the first base 10, the first section 432 of the cam 43 is parallel to the length extension direction of the elastic member 20. In this state, the first section 432 of the cam 43 is closer to the convex portion 221 of the elastic member 20 than the second section 433. In other words, there is no structural interference between the second section 433 of the cam 43 and the elastic member 20.

[0045] When the first component P1 is to be assembled and inserted into the second component P2, Figure 6, the handle 41 is rotated counterclockwise along the first direction D1. When the handle 41 rotates relative to the handle shaft 411, the handle 41 drives the connecting rod 42 through the first rotating shaft 421 of the connecting rod 42. The connecting rod 42 drives the first rotating shaft 421 of the connecting rod 42 to move as the handle 41 pivots relative to the handle shaft 411, and drives the second rotating shaft 422 to rotate relative to the cam shaft 431 of the cam 43, and drives the cam 43 to rotate counterclockwise. During the counterclockwise rotation process of the cam 43, the second section 433 of the cam 43 begins to contact the lower surface 2212 of the protrusion 221 of the second end 22 of the elastic member 20. The second section 433 of the cam 43 pushes against the protrusion 221 of the elastic member 20 so that the second end 22 of the elastic member 20 is pushed close to the first side plate 12.

[0046] See also Figures 8 to 10 When the second end 22 of the elastic member 20 is pushed to move toward the second inner side away from the second base 30, the cam 43 can be pressed against the surface of the protrusion 221 and smoothly pass over the protrusion 221. After passing over the protrusion 221 of the elastic member 20, the cam 43 can continue to rotate and continue to rotate until the handle 41 is pressed against the second side plate 32. Fig.11 shown.

[0047] It is worth noting that, in the process of the cam 43 pushing against the protrusion 221 of the elastic member 20, the second end 22 of the elastic member 20 is pushed close to the first side plate 12. At this time, the second end 22 of the elastic member 20 is deformed and accumulates elastic force. Since the first end 21 of the elastic member 20 is fixedly attached to the first side plate 12 of the first base 10, the elastic restoring force of the elastic member 20 itself makes the protrusion 221 of the second end 22 normally have a restoring force to return to the same plane as the first end 21.

[0048] See also Figure 7Before the second section 433 of the cam 43 passes over the lower surface 2212 of the protrusion 221 of the elastic member 20 and rotates to above the upper surface of the protrusion 221, the second section 433 of the cam 43 must resist the reaction force indirectly generated by the elastic restoring force when passing over the lower surface 2212 of the protrusion 221 of the elastic member 20. Therefore, the force applied to the handle 41 to drive the cam 43 to rotate must be able to link the pushing force of the cam 43 against the lower surface 2212 of the protrusion 221 of the elastic member 20 to be greater than the reaction force generated by the elastic restoring force of the elastic member 20, and the force applied to the handle 41 to drive the cam 43 to rotate will also be converted into a force applied to the second base 30. Specifically, when the cam 43 is driven by the handle 41 so that the second section 433 pushes upward against the lower surface 2212 of the protrusion 221 of the elastic member 20 as the cam 43 rotates, the second section 433 of the cam 43 is simultaneously subjected to the reaction force of the lower surface 2212 of the protrusion 221 of the elastic member 20. Since the second base 30 and the cam 43 are pivotally connected through the cam shaft 431, the second base 30 is also subjected to the reaction force of the lower surface 2212 of the protrusion 221 of the elastic member 20 pushing against the second section 433 of the cam 43, and indirectly, the second base 30 generates a force to combine with the first base 10. In other words, the user only needs to rotate the handle 41, and the linkage of the linkage assembly 40 can generate a force for the second base 30 to be directed toward the first base 10, and the downward force generated by the second base 30 can assist the second component P2 on the second base 30 to be inserted into the first component P1 of the first base 10, thereby achieving the purpose of labor saving.

[0049] In addition, it can be seen from the above description that the downward coupling force generated by the cam 43 and applied to the second base 30 is related to the force of the cam 43 passing over the elastic member 20. Therefore, in some embodiments, the elastic member 20 can change its material properties according to the coupling force required for the first component P1 and the second component P2 to be coupled.

[0050] See also Fig.11 and Fig.12 When the handle 41 rotates and drives the cam 43 to pass over the protrusion 221 of the elastic member 20, the second component P2 completes the assembly with the first component P1, and the second end 22 of the elastic member 20 returns to the initial state, and the handle 41 can continue to rotate to a flat state, that is, the handle 41 is roughly parallel to the second bottom plate 31 of the second base 30. Here, the flat state of the handle 41 is a state in which the handle 41 rotates to not protrude from the first inner side of the first base 10. In this state, it is ensured that the assembled first component P1 and the second component P2 will not occupy other unnecessary spaces.

[0051] See also Fig.11 and Fig.12When the first component P1 and the second component P2 are assembled and the handle 41 is rotated to a flat position, the cam 43 is rotated to a position where the recess between the third section 434 and the fourth section 435 corresponds to the protrusion 221 of the elastic member 20, thereby allowing the second end 22 of the elastic member 20 to return to a coplanar state with the first end 21.

[0052] See also Fig.13 and Fig.14 When the first component P1 and the second component P2 are to be separated from the assembled state, the handle 41 is first rotated in the opposite direction (compared to the direction during assembly) along the second direction D2. Fig.13 The perspective shown is a clockwise rotation, so that the handle 41 rotates from the lying state to the upright state. At this time, the handle 41 drives the cam 43 to rotate clockwise through the connecting rod 42. During the clockwise rotation process of the cam 43, the cam 43 contacts the upper surface 2211 of the protrusion 221 of the elastic member 20 at the junction of its second section 433 and the third section 434. In this state, since the third section 434 and the upper surface 2211 of the protrusion 221 are planes roughly parallel to the first bottom plate 11 or U-shaped or V-shaped grooves with an opening facing upward, rather than inclined surfaces inclined toward the second bottom plate 31 of the second base 30, the junction of the second section 433 and the third section 434 of the cam 43 that contacts the upper surface 2211 of the protrusion 221 of the elastic member 20 is affected by the shape of the upper surface 2211 of the protrusion 221 of the elastic member 20. The cam 43 is limited in shape and cannot pass over the upper surface 2211 of the protrusion 221 of the elastic member 20. Therefore, the cam 43 will not push the protrusion 221 of the elastic member 20 in the second inner direction away from or close to the second base 30, and the connection between the second section 433 and the third section 434 of the cam 43 will not pass over the upper surface 2211 of the protrusion 221 downward. Therefore, when the handle 41 drives the cam 43 to rotate clockwise through the connecting rod 42, the upper surface 2211 of the protrusion 221 of the elastic member 20 will not move in the second inner direction away from or close to the second base 30 due to the push of the cam 43. Therefore, the third section 434 of the cam 43 can stably abut against the upper surface 2211 of the protrusion 221 of the elastic member 20. In this way, the second base 30 is supported by the state that the cam 43 abuts against the elastic member 20, and when the handle 41 is continuously rotated so that the cam 43 continues to exert force on the protrusion 221 of the elastic member 20, the cam 43 pushes against the downward force exerted by the protrusion 221 of the elastic member 20, so that the protrusion 221 of the elastic member 20 also generates a corresponding upward reaction force on the cam 43, so that the second base 30 obtains an auxiliary force to separate upward from the first base 10, and the user can thereby labor-savingly pull the second base 30 upward to separate the second component P2 of the second base 30 from the first component P1.

[0053] As can be seen from the foregoing, when the first component P1 and the second component P2 are to be separated, the convex portion 221 of the elastic member 20 can provide support for the second base 30, and the cam 43 is rotated in conjunction with the rotation of the handle 41 and applies a downward force to the convex portion 221 of the elastic member 20 while pressing against the first base 10, so that the first base 10 can be stabilized in a fixed position. When applying force to pull out the second base 30, the user does not need to stabilize the first base 10 separately. In addition to being extremely convenient to use, it also achieves a labor-saving effect.

[0054] In some embodiments, the number of the elastic members 20 is two and they are respectively disposed on the two first side plates 12 of the first base 10, and at the same time, the number of the connecting rods 42 and the cams 43 of the linkage assembly 40 is also two. In this embodiment, the two ends of the handle 41 are respectively pivoted to a connecting rod 42, and the other end of each connecting rod 42 pivoted to the handle 41 is respectively pivoted to a cam 43. In this way, the handle 41 can simultaneously drive the two cams 43 and the two elastic members 20 to act, which not only makes the force more balanced, but also strengthens the force generation and improves the labor-saving effect.
