Mobile phone construction and housing assembly comprising same

Abstract

A handle structure and a case assembly comprising the same are provided. The handle structure is adapted to be mounted on a sliding plate member and to slide the sliding plate member into a case. The handle structure comprises a handle member and a locking protrusion. The handle member is adapted to be pivotably arranged on the sliding plate member with a locking position and an opening position. The locking protrusion is slidably arranged on the handle member and is adapted to abut against the case to slide the sliding plate member into the case. The locking protrusion has a locking surface, and the locking surface has an end edge opposite to a rotation axis of the handle member. When the handle member is rotated from the opening position to the locking position, the distance between the end edge of the locking surface of the locking protrusion and the rotation axis of the handle member decreases. The assembly convenience of the case, such as a server mainframe, can be improved when being pulled out or pushed in.

Description

Technical Field

[0001] The present invention relates to a handle mechanism and a housing assembly including the same, and more particularly to a handle mechanism and a housing assembly including the same. Background Technology

[0002] In the cloud computing field, servers play a crucial role, providing and implementing various cloud services required by internet users. Their applications span diverse sectors such as gaming, language processing, finance, biomedicine, search engines, e-commerce, and social media. To continuously improve service quality and internal management, operators maximize the number of components within the limited space of a server and meticulously plan its internal layout. As a result, server configurations become increasingly compact; server chassis may house multiple server hosts, and each server host contains an ever-growing number of components, making it increasingly heavy.

[0003] To facilitate the movement and assembly of server units within the server chassis during maintenance and repair work, server chassis are typically designed to slide, and often include handles for maneuvering and securing the server. However, whether pulling the server out of or pushing it into the chassis, the handles must be opened. Therefore, further improving the ease of assembly during these actions becomes a significant design challenge. Summary of the Invention

[0004] The present invention provides a handle mechanism and a housing assembly including the handle, thereby improving the ease of assembly of a housing such as a server host when it is pulled out or pushed in.

[0005] An embodiment of the present invention discloses a handle mechanism adapted to be mounted on a sliding plate and to allow the sliding plate to slide into a housing. The handle mechanism includes a handle and a latching protrusion. The handle is adapted to be pivotally disposed on the sliding plate and has an engaged position and an open position. The latching protrusion is slidably disposed on the handle and adapted to abut against the housing to allow the sliding plate to slide into the housing. The latching protrusion has a latching surface with an end edge relatively away from a rotation axis of the handle. As the handle rotates from the open position toward the engaged position, the distance from the end edge of the latching surface of the latching protrusion to the rotation axis of the handle decreases.

[0006] Another embodiment of the present invention discloses a housing assembly adapted to be slidably disposed within a housing. The housing assembly includes a support plate and a handle mechanism. The support plate is slidably disposed within the housing. The handle mechanism includes a handle member and a latching protrusion. The handle member is adapted to be pivotally disposed on the support plate and has an engaged position and an open position. The latching protrusion is slidably disposed on the handle member and adapted to abut against the housing to allow the support plate to slide into the housing. The latching protrusion has a latching surface, and the latching surface has an end edge relatively away from a rotation axis of the handle member. When the handle member rotates from the open position to the engaged position, the distance from the end edge of the latching surface of the latching protrusion to the rotation axis of the handle member decreases.

[0007] According to the above embodiment, the handle mechanism and the housing assembly including it have a slidably mounted latching protrusion. Therefore, when the guide slope of the latching protrusion is pushed against the front side of the housing, the latching protrusion automatically retracts to avoid interference with the housing. Once the latching protrusion aligns with the latching hole of the housing, the latching protrusion engages with the latching hole. In this way, when it is inconvenient for the operator to operate the handle mechanism, or when the operator does not wish to open the handle, the operator can directly push the support plate into the housing without opening the handle.

[0008] Furthermore, when the handle rotates from the engaged position to the open position, the distance from the edge of the latching face of the latching protrusion to the rotation axis of the handle increases, thereby increasing the sliding stroke of the handle mechanism to allow the support plate to slide into the housing. Conversely, when the handle rotates from the open position to the engaged position, the distance from the edge of the latching face of the latching protrusion to the rotation axis of the handle decreases, to prevent the latching protrusion from colliding or interfering with other components near the housing. This improves upon the previous design where the latching protrusion and handle were integrated, making it difficult to balance the increased sliding stroke of the handle mechanism to allow the support plate to slide with the effort-saving ratio of the handle mechanism.

[0057] The handle mechanism of this embodiment is adapted to be mounted on a sliding plate and to slide the plate into the housing. The sliding plate and the housing can be any objects that can slide relative to each other; that is, the sliding plate and the housing can be a server host disk and its outer casing that can slide relative to each other, or a server host's outer casing and its rack that can slide relative to each other, or a hard drive carrier and a server host's housing that can slide relative to each other. Since the handle mechanism of this embodiment has a generally similar structure in different applications, only one application will be described below, and other applications will not be elaborated upon.

[0058] Please see Figures 1 to 4 . Figure 1 This is a perspective view of the housing assembly 1 and the housing 30 according to the first embodiment of the present invention. Figure 2 for Figure 1 A partial 3D schematic diagram. Figure 3 for Figure 2 A schematic diagram of its breakdown. Figure 4 for Figure 2 A cross-sectional schematic diagram.

[0059] In this embodiment, the housing assembly 1 is adapted to be slidably disposed on a housing 30. The housing assembly 1 is, for example, a disk drive 20 assembly of a server chassis, used to mount electronic components such as the motherboard, hard drive, and fan. The housing 30 is, for example, the outer shell of a server chassis. In this embodiment, the height of the housing 30 is 6U, and the height of the housing assembly 1 is 3U, but this is not a limitation. In other embodiments, the height of the housing may remain 6U, but the height of the housing assembly 1 may be changed to 1U. Alternatively, the heights of both the housing and the housing assembly may be changed to 2U. The housing 30 in this embodiment has a front side 32 and a latching hole 34, the latching hole 34 being separate from the front side 32 and having a receiving surface 36 near the front side 32. Furthermore, the front side 32 is, for example, secured to a server rack (not shown) by screws 31.

[0060] The housing assembly 1 includes a support tray 20 and two sets of handle mechanisms 10. The support tray 20 is slidably disposed within the housing 30 and is used to mount electronic components such as the motherboard, hard drive, and fan. The support tray 20 has a sliding plate 22 and a cutout structure 24. The cutout structure 24 is located on the sliding plate 22.

[0061] Since the two sets of handle mechanisms 10 have similar structures, only one set of handle mechanisms 10 will be described. The handle mechanism 10 includes a handle member 100 and a latching protrusion 300. The handle member 100 is adapted to be pivotally mounted on the support plate 20 and has an engaged position (e.g., ...). Figure 4 The position of the handle 100 shown) and an open position (as shown) Figure 8 (The position of the handle 100 is shown). More specifically, the housing assembly 1 may further include a first fixing member 150 and a second fixing member 160. The first fixing member 150 is fixed to the sliding plate 22 of the support plate 20, for example, by screws or other fasteners. The second fixing member 160 is fixed to the first fixing member 150, and the handle 100 is located between the first fixing member 150 and the second fixing member 160. Furthermore, the second fixing member 160 has a post 161, and the handle 100 has a shaft hole 110. The post 161 of the second fixing member 160 passes through the shaft hole 110 of the handle 100 and is fixed to the first fixing member 150, for example, by screws or other fasteners, so that the handle 100 can rotate relative to the first fixing member 150 and the second fixing member 160 in the direction R.

[0062] In this embodiment, the handle 100 may further have a first guide structure 120. The first fixing member 150 further has a second guide structure 151. The first guide structure 120 and the second guide structure 151 are, for example, mutually matching guide posts and arc-shaped guide grooves, and the guidance of the first guide structure 120 and the second guide structure 151 makes the rotation process of the handle 100 relative to the first fixing member 150 smoother. However, the first guide structure 120 and the second guide structure 151 in this embodiment are not intended to limit the invention. In other embodiments, the design of the first guide structure and the second guide structure may be omitted.

[0063] In this embodiment, the handle mechanism 10 is fixed to the sliding plate 22 of the support plate 20, but this is not a limitation. In other embodiments, the handle mechanism may also be fixed to the base plate of the support plate.

[0064] In this embodiment, the housing assembly 1 further includes a push-abutment 200. The push-abutment 200 and the handle member 100 are, for example, different parts of the same sheet material, that is, the push-abutment 200 is integrally formed and connected to the handle member 100. The push-abutment 200 has a push-abutment surface 210, and the push-abutment surface 210 is adapted to abut against the front side 32 of the housing 30 to allow the support plate 20 to slide out of the housing 30.

[0065] In this embodiment, the push-abutment 200 is integrally formed and connected to the handle 100, but this is not the limitation. In other embodiments, the push-abutment can also be assembled to the handle by means of snap-fit, screw-in, riveting, or other connection methods.

[0066] The snap-fit ​​protrusion 300 is slidably disposed on the handle 100 and is adapted to pass through the hollow structure 24 and abut against the abutting surface 36 of the housing 30 near the front side 32 of the snap-fit ​​hole 34, so that the carrier plate 20 slides into the housing 30. More specifically, the housing assembly 1 may also include a guide cover 350 and a plurality of first elastic members 400. The guide cover 350 is fixed to the handle 100 and has a guide groove 351, on which the snap-fit ​​protrusion 300 is slidably located. That is, the width of the snap-fit ​​protrusion 300 matches the width of the guide groove 351, so that the snap-fit ​​protrusion 300 is guided by the guide cover 350 and can move linearly in direction D1. One end of each first elastic member 400 is connected to the snap-fit ​​protrusion 300, and the other end of each first elastic member 400 is connected to the guide cover 350. The first elastic element 400 is, for example, a compression spring. When the latching protrusion 300 is driven by an external force to slide in the opposite direction D1, the latching protrusion 300 and the guide cover 350 will jointly compress the first elastic element 400, allowing the first elastic element 400 to store elastic potential energy. Conversely, if the external force causing the latching protrusion 300 to slide in the opposite direction D1 disappears, the first elastic element 400 will release its elastic potential energy, causing the latching protrusion 300 to slide relative to the handle 100 in the direction D1.

[0067] In this embodiment, the number of first elastic elements 400 is two, but this is not a limitation. In other embodiments, the number of first elastic elements may be one or more than three.

[0068] In this embodiment, the two opposite ends of the first elastic member 400 are respectively connected to the snap-fit ​​protrusion 300 and the guide cover 350, but this is not a limitation. In other embodiments, the two opposite ends of the first elastic member may also be connected to the snap-fit ​​protrusion and the handle respectively.

[0069] In this embodiment and other embodiments, the handle 100 may also have two first guide portions 130, and the latching protrusion 300 has two second guide portions 310. The two first guide portions 130 of the handle 100 are adapted to be guided by the two second guide portions 310 of the latching protrusion 300 so that the latching protrusion 300 slides relative to the handle 100 in a straight line.

[0070] The latching protrusion 300 of this embodiment has a latching surface 320 and a push-receiving inclined surface 330. The push-receiving inclined surface 330 faces away from the latching surface 320. The latching surface 320 has an end edge 321 that is relatively far away from the rotation axis O of the handle 100. When the handle 100 is in the engaged position and the latching protrusion 300 is engaged in the latching hole 34 of the housing 30, the latching surface 320 of the latching protrusion 300 faces the abutting surface 36. When the handle 100 is in the open position, the latching protrusion 300 is outside the latching hole 34 and the latching protrusion 300 is not stopped by the stop member 162. When the handle 100 is in the engaged position and the support plate 20 is about to slide into the housing 30, the push-receiving inclined surface 330 of the latching protrusion 300 is pushed by the front side 32 of the housing 30 and automatically slides in the opposite direction D1.

[0071] In this embodiment, there are two of each of the first guide section 130 and the second guide section 310, but this is not a limitation. In other embodiments, the number of the first guide section and the second guide section may be one or more than three. Furthermore, in embodiments with a guide cover, the design of the first guide section and the second guide section may be omitted. Conversely, in embodiments with the first guide section and the second guide section, the design of the guide cover may be omitted.

[0072] In this embodiment, the latching protrusion 300 slides along a straight line, but is not limited to this. In other embodiments, the latching protrusion may also slide along a curve.

[0073] In this embodiment and other embodiments, the second fastener 160 may also have a stop 162, which is adapted to stop the snap-fit ​​protrusion 300 to limit the extension and retraction of the snap-fit ​​protrusion 300.

[0074] In this embodiment, the stop 162 is located on the second fixing member 160, but this is not a limitation. In other embodiments, the stop may be located on the support plate or other objects fixed to the support plate.

[0075] In this embodiment, the stop 162 is used to limit the extension and retraction of the latching protrusion 300 in the engaged position to prevent the latching protrusion 300 from hitting components (such as server racks, server host casings, or adjacent hard drive carriers) next to the housing 30 due to excessive extension, but this is not a limitation. In other embodiments, the stop 162 may be omitted, allowing the latching protrusion to naturally retract in the opposite direction D1 after hitting the components (such as server racks, server host casings, or adjacent hard drive carriers) next to the housing.

[0076] In this embodiment, the housing assembly 1 may further include a snap-fit ​​member 500 and a plurality of second elastic members 600. The snap-fit ​​member 500 includes a body portion 510 and a first snap portion 520. The body portion 510 is slidably disposed on the handle member 100 along the direction D2, and the first snap portion 520 is connected to the body portion 510 and is used to snap onto the second snap portion 26 (e.g., on the support plate 20). Figure 4 (As shown) the relative position of the handle 100 and the support plate 20 is fixed. One end of each second elastic member 600 is connected to the body portion 510 of the latching member 500, and the other end of each second elastic member 600 is connected to the handle 100. The second elastic member 600 is, for example, a compression spring, and when the latching member 500 is not subjected to any other external force, the second elastic member 600 is adapted to normally engage the first latch portion 520 of the latching member 500 with the second latch portion 26 of the support plate 20 to fix the relative position of the handle 100 and the support plate 20.

[0077] In this embodiment, there are two second elastic elements 600, but this is not a limitation. In other embodiments, the number of second elastic elements may be one or more than three.

[0078] In this embodiment, the housing assembly 1 may further include an actuating elastic element 700. One end of the actuating elastic element 700 is connected to the first fixing member 150, and the other end of the actuating elastic element 700 is connected to the handle member 100. The actuating elastic element 700 is, for example, a tension spring, and when the first latch 520 of the latch member 500 is unfastened to the second latch 26 of the support plate 20, it makes the operation of rotating the handle member 100 toward the open position or moving the handle member 100 toward the open position easier.

[0079] In this embodiment, the housing assembly 1 has a push-abutment protrusion 200, but this is not a limitation. In embodiments where an actuating elastic element 700 is provided, or when there is no need for effort reduction during the pulling out of the support plate 20, the push-abutment protrusion 200 may be omitted. Furthermore, the design of the actuating elastic element 700 is not intended to limit the invention; in embodiments where there is no need for automatic handle opening, the actuating elastic element 700 may be omitted.

[0080] Please see Figure 4 and Figure 5 . Figure 5 for Figure 2 A cross-sectional view of the handle 100 in the open position. (See diagram below.) Figure 4 As shown, the handle 100 is in the engaged position, and the first latching portion 520 of the latching member 500 is engaged with the second latching portion 26 of the carrier plate 20, and the latching protrusion 300 is engaged with the latching hole 34 of the housing 30. Due to the stop of the stop member 162, the distance X1 from the end edge 321 of the latching surface 320 of the latching protrusion 300 to the rotation axis O is shortened. In addition, the ratio of the distance L1 from the first latching portion 520 to the rotation axis O to the distance L2 from the latching surface 320 of the latching protrusion 300 to the rotation axis O in the sliding direction D1 of the latching protrusion 300 can be increased to more than 10, making it easier to slide the carrier plate 20 into the housing 300 using the handle mechanism 10. Furthermore, the shortening of the distance L2 between the snapping surface 320 of the snapping protrusion 300 abutting the abutting surface 36 and the rotation axis O in the sliding direction D1 of the snapping protrusion 300 is due not only to the shortened protrusion of the snapping protrusion 300, but also to the relatively distant design position of the rotation axis O from the snapping member 500. In other words, the design position of the rotation axis O is closer to the abutting protrusion 200. Therefore, the ratio of the distance L1 from the first snapping part 520 to the rotation axis O to the straight-line distance L3 from the abutting surface 210 of the abutting protrusion 200 to the rotation axis O can be increased to more than 10, making it easier for the handle mechanism 10 to slide the carrier plate 20 out of the housing 30.

[0081] Conversely, such as Figure 5As shown, the handle 100 is in the open position. Because the telescopically designed latching protrusion 300 is not stopped by the stop 162, allowing it to slide along direction D1, the distance X2 from the end edge 321 of the latching surface 320 to the rotation axis O can be increased. In other words, the distance L2 between the latching surface 320 of the latching protrusion 300 abutting against the abutting surface 36 and the rotation axis O along the sliding direction D1 of the latching protrusion 300 can be increased, thereby further increasing the sliding stroke of the handle mechanism 10 driving the carrier plate 20 into the housing 30 to more than 10 mm. Furthermore, the design value of the straight-line distance from the pushing surface 210 of the pushing protrusion 200 to the rotation axis O can also be correspondingly lengthened, further increasing the sliding stroke of the handle mechanism 10 driving the carrier plate 20 out of the housing 30 to more than 10 mm.

[0082] Please see Figures 6 to 10 , Figures 6 to 10 for Figure 2 A schematic diagram of the first operation of the handle mechanism 10.

[0083] like Figure 4 As shown, the handle 100 is in the engaged position, and the first latching portion 520 of the latching member 500 is engaged with the second latching portion 26 of the carrier plate 20, and the latching protrusion 300 is engaged with the latching hole 34 of the housing 30. When the handle 100 is in the engaged position, the end edge 321 of the latching surface 320 of the latching protrusion 300 has a short distance X1 from the rotation axis O (e.g., ...). Figure 4 As shown), this design prevents the snap-fit ​​protrusion 300 from colliding or interfering with other components (not shown) adjacent to the housing 30. Next, as... Figure 6 As shown, the operator can push the latching member 500 in direction A to release the latching relationship between the first latching part 520 of the latching member 500 and the second latching part 26 of the carrier plate 20. Just as the first latching part 520 of the latching member 500 and the second latching part 26 of the carrier plate 20 are released, the pre-stored elastic force F1 in the actuating elastic member 700 will be released, which will drive the handle member 100 to rotate in direction B. Figure 7 As shown, under the action of the elastic force F1 of the actuating elastic element 700 or when the operator manually rotates the handle 100 in direction B, the pushing surface 210 of the pushing protrusion 200 of the handle mechanism 10 will abut against the front side 32 of the housing 30 (under the action of external force F2), causing the bearing plate 20 to slide out of the housing 30 in direction C. Figure 8As shown, when the elastic force F1 of the actuating elastic element 700 continues to act, or when the operator manually rotates the handle 100 in the direction B, the pushing surface 210 of the pushing protrusion 200 of the handle mechanism 10 will continue to abut against the front side 32 of the housing 30, causing the carrier plate 20 to slide out of the housing 30 in the direction C. In this way, the carrier plate 20 can be slid out of the housing 30 in the direction C by the handle mechanism 10 with less effort, and the electrical connection element (not shown) inside the carrier plate 20 can be disengaged from the electrical connection element (not shown) on the housing 30 or the cabinet (not shown).

[0084] Conversely, such as Figure 9 As shown, when the operator manually rotates the handle 100 in direction E, the latching surface 320 of the latching protrusion 300 pushes against the bearing surface 36 (under the action of external force F3), causing the bearing plate 20 to retract into the housing 30 in direction F. Furthermore, because the latching protrusion 300 is not restricted by the stop 162, and the end edge 321 of the latching surface 320 of the latching protrusion 300 has a relatively long distance X2 from the rotation axis O (e.g., ... Figure 5 As shown), the latching protrusion 300 can abut against the bearing surface 36 earlier, thus extending the sliding stroke of the bearing plate 20 driven by the handle mechanism 10. Next, as... Figure 10 As shown, when the operator manually rotates the handle 100 in direction E, the latching protrusion 300 is stopped by the stop 162 (under the action of external force F4) and retracts in direction G. This limits the protrusion of the latching protrusion 300, thus preventing it from colliding with other components next to the housing 30. In this way, the carrying plate 20 can be slid into the housing 30 in direction F with less effort through the handle mechanism 10, allowing the electrical connection components (not shown) inside the carrying plate 20 to be connected to the electrical connection components (not shown) on the housing 30 or the cabinet (not shown).

[0085] In summary, when the handle 100 rotates from the engaged position to the open position, the distance from the end edge 321 of the latching surface 320 of the latching protrusion 300 to the rotation axis O of the handle 100 increases, thereby increasing the sliding stroke of the handle mechanism 10 in sliding the support plate 20 into the housing 30. Conversely, when the handle 100 rotates from the open position to the engaged position, the distance from the end edge 321 of the latching surface 320 of the latching protrusion 300 to the rotation axis O of the handle 100 decreases, to avoid collision or interference between the latching protrusion 300 and other components near the housing 30. This improves upon the previous design where the latching protrusion 300 and the handle 100 were integrated, making it difficult to balance the increased sliding stroke of the handle mechanism 10 in sliding the support plate 20 with the force-saving ratio of the handle mechanism 10.

[0086] Please see Figure 11 and Figure 12 . Figure 11 and Figure 12 for Figure 2 A schematic diagram of the second operation of the handle mechanism 10.

[0087] like Figure 11 and Figure 12 As shown, when the handle 100 is in the engaged position, the operator can also choose to push the carrier plate 20 directly into the housing 30 along direction H without opening the handle 100. Since the latching protrusion 300 is slidably disposed on the handle 100, when the guide slope of the latching protrusion 300 is pushed by the front side 32 of the housing 30 (under the action of external force F5), the latching protrusion 300 will slide along direction I and avoid interference between the latching protrusion 300 and the housing 30. When the latching protrusion 300 is aligned with the latching hole 34 of the housing 30, the latching protrusion 300 is then engaged with the latching hole 34 of the housing 30 by the action of the first elastic member 400. In this way, in addition to avoiding the unexpected impact between the handle mechanism 10 and the housing 30 caused by the operator forcibly pushing the bearing plate 20 into the handle when the handle 100 is in the engaged position, when the housing assembly 1 is located at a high position and it is inconvenient for the operator to operate the handle mechanism 10, the operator can also choose not to operate the handle mechanism 10 and directly push the bearing plate 20 into the housing 30.

[0088] According to the handle mechanism and housing assembly comprising the above embodiment, since the latching protrusion is slidably disposed on the handle, when the guide slope of the latching protrusion is pushed by the front side of the housing, the latching protrusion will automatically retract to avoid interference with the housing. When the latching protrusion is aligned with the latching hole of the housing, the latching protrusion is then engaged with the latching hole of the housing by the action of the first elastic member. In this way, when it is inconvenient for the operator to operate the handle mechanism, or when the operator does not want to open the handle, the operator can directly push the carrier plate into the housing without opening the handle.

[0089] Furthermore, when the handle rotates from the engaged position to the open position, the distance from the edge of the latching face of the latching protrusion to the rotation axis of the handle increases, thereby increasing the sliding stroke of the handle mechanism to allow the support plate to slide into the housing. Conversely, when the handle rotates from the open position to the engaged position, the distance from the edge of the latching face of the latching protrusion to the rotation axis of the handle decreases, to prevent the latching protrusion from colliding or interfering with other components near the housing. This improves upon the previous design where the latching protrusion and handle were integrated, making it difficult to balance the increased sliding stroke of the handle mechanism to allow the support plate to slide with the effort-saving ratio of the handle mechanism.

[0090] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the claims defined in the appended specification.
