Summary of the Invention

[0004] The purpose of this invention is to provide a chassis device for server rooms, which achieves the effects of labor saving and positioning by setting sliding components and positioning components between the chassis unit and the receiving space, effectively reducing the force applied when installing the chassis unit to the receiving space, and avoiding the occurrence of bumps / scratches.

[0005] Another objective of this invention is to provide a chassis assembly for a server room, which utilizes ball bearings and rollers to construct a sliding component between the bottom of the receiving space and the chassis unit, providing sufficient support and achieving a labor-saving function. Furthermore, the positioning component, consisting of rollers at the top and bottom of the receiving space in conjunction with guide grooves on the chassis unit, simultaneously achieves labor-saving and limiting functions, allowing the chassis unit to be smoothly placed into or removed from the receiving space of the chassis assembly, avoiding collisions or scratches with the inner wall of the receiving space. On the other hand, the handle assembly pivotally connected to the front end of the chassis unit works in conjunction with the positioning component when the chassis unit is placed into or removed from the receiving space.

[0009] In one embodiment, when the rear end of the chassis unit is inserted into the receiving space through the opening, the handle assembly is pre-rotated to a first position, allowing the positioning assembly to align with the tail end of the guide groove.

[0010] In one embodiment, when the tail end of the guide groove approaches the positioning component, the handle component engages with the positioning component through the arc-shaped meshing groove, causing the handle component to rotate to the second position.

[0011] In one embodiment, when the handle assembly is rotated to the second position, the positioning assembly is positioned at the tail end of the guide groove and engages with the tail end of the arc-shaped engagement groove, the chassis unit is locked in the receiving space, and the grip end is retracted to the front end of the chassis unit.

[0012] In one embodiment, the width of the arc-shaped engagement groove is greater than the diameter of the positioning component, and gradually narrows from the opening end to the tail end. The arc-shaped engagement groove also includes a locking point disposed at the tail end of the arc-shaped engagement groove, which engages with the positioning component when the chassis unit is fully accommodated in the receiving space.

[0013] In one embodiment, the gripping end is subjected to force by the front end protruding and driving the handle assembly to rotate from the second position to the first position, and the positioning component is limited to the opening end of the guide groove and the arc-shaped engagement groove, allowing the chassis unit to move out of the receiving space through the opening.

[0014] In one embodiment, the handle assembly is pivotally mounted on the chassis unit, the pivot being located between the tail end of the guide groove and the front end of the chassis unit.

[0015] In one embodiment, the hook end is located inside the chassis unit, and the gripping end protrudes from the front end of the chassis unit through the front opening.

[0016] In one embodiment, the handle assembly maintains at least partial intersection between the arcuate engagement groove and the guide groove when rotated or swung.

[0017] In one embodiment, the guide trench extends from the rear end of the chassis unit toward the front end along a first direction.

[0018] In one embodiment, the sliding component includes a plurality of balls disposed at the bottom of the chassis unit along a first direction, spatially relative to the bottom of the receiving space, wherein when the chassis unit is inserted into or removed from the receiving space through the opening along the first direction, the plurality of balls abut against the bottom of the receiving space to support the chassis unit.

[0019] In one embodiment, a plurality of balls are arranged in pairs on opposite sides of the positioning component.

[0020] In one embodiment, the sliding assembly includes a plurality of support rollers arranged along a first direction on two opposite sides of the receiving space, and the axes of the plurality of support rollers are parallel to a third direction.

Figure 7 This is a schematic diagram showing the handle assembly rotated to the first position. Figure 8 This is a schematic diagram showing the transition state of the handle assembly as it rotates from the first position to the second position. Figure 9 This is a schematic diagram showing the handle assembly rotated to the second position. (Reference) Figures 1 to 9 This invention provides a chassis assembly 9 for a server room. The chassis assembly 9 includes multiple receiving spaces 8 with the same structure arranged in a single or multiple rows, each receiving space 8 allowing the installation of one chassis unit 1. In this embodiment, in addition to including at least one receiving space 8 paired with at least one chassis unit 1 for installation, the chassis assembly 9 also includes a sliding component 2, a positioning component 3, and a handle component 4 to achieve effort-saving and positioning effects when the chassis unit 1 is installed into the receiving space 8, effectively reducing the force applied during installation and avoiding bumps / scratches. The following description is only an example of a single receiving space 8 paired with a single chassis unit 8 in the chassis assembly 9 and is not intended to limit the invention. In this embodiment, the receiving space 8 includes an opening 80, which faces a first direction, for example, parallel to the X-axis. The chassis unit 1 is assembled by its rear end 10b being inserted into or removed from the receiving space 8 through the opening 80 along the first direction (i.e., parallel to the X-axis). The sliding component 2 includes, for example, a plurality of balls 20 disposed between the bottom of the receiving space 8 and the bottom 10d of the chassis unit 1 along a first direction (i.e., parallel to the X-axis direction), allowing the chassis unit 1 to slide relative to the receiving space 8 along the first direction (i.e., parallel to the X-axis direction) via the sliding component 2, and supporting the chassis unit 1. In this embodiment, the positioning component 3 is disposed within the receiving space 8, wherein the chassis unit 1 further includes a guide groove 11 disposed on the chassis unit 1 along the first direction (i.e., parallel to the X-axis direction), the guide groove 11 being spatially relative to the positioning component 3, wherein when the chassis unit 1 is inserted into or removed from the receiving space 8 through the opening 80 along the first direction (i.e., parallel to the X-axis direction), the positioning component 3 is confined within the guide groove 11. The handle assembly 4 is pivotally mounted on the front end 10a of the chassis unit 1, and includes a latch end 41 and a grip end 42 facing each other. The latch end 41 is spatially positioned relative to the positioning component 3 and the guide groove 11, and the grip end 42 protrudes from the front end 10a of the chassis unit 1. The handle assembly 4 is rotated to a first position (e.g., Figure 7 As shown), the hook end 41 has an arc-shaped engagement groove 40 that aligns with the guide groove 11 and the positioning component 3, and the arc-shaped engagement groove 40 allows engagement with the positioning component 3 to rotate the handle assembly 4 to a second position (e.g., Figure 9 (As shown).

[0075] In this embodiment, the positioning component 3 includes a plurality of positioning rollers 30, which are spaced apart along a first direction (i.e., parallel to the X-axis direction). The axis A1 of the plurality of positioning rollers 30 is parallel to a second direction (i.e., the Z-axis direction), and the second direction is perpendicular to the first direction. Furthermore, the plurality of positioning rollers 30 of the positioning component 3 are arranged in pairs, including at least one pair of positioning rollers 30 respectively disposed in the middle of the top 80a and bottom 80b of the accommodating space 8. The axis A1 of at least one pair of positioning rollers 30 is parallel to the second direction (i.e., the Z-axis direction) and spatially relative to the guide grooves 11 of the top 10c and bottom 10d of the chassis unit 1, respectively.

[0076] In this embodiment, the sliding component 2 includes a plurality of balls 20, which are disposed along a first direction (i.e., parallel to the X-axis) at the bottom 10d of the chassis unit 1, spatially relative to the bottom 80b of the receiving space 8. Preferably, the plurality of balls 20 are further disposed in pairs on opposite sides of the positioning component 3. For example, the plurality of balls 20 are arranged symmetrically with respect to the positioning component 3. Of course, the present invention is not limited thereto. In this embodiment, when the chassis unit 1 is inserted into or removed from the receiving space 8 through the opening 80 along the first direction (i.e., parallel to the X-axis), the plurality of balls 20 abut against the bottom 80b of the receiving space 8 to support the chassis unit 1, reducing the contact area between the chassis unit 1 and the receiving space 8, and optimizing the displacement of the chassis unit 1 relative to the receiving space 8. Of course, the present invention is not limited thereto.

[0077] In this embodiment, the guide grooves 11 of the top 10c and bottom 10d of the chassis unit 1 are aligned with the positioning component 3 with their open ends, allowing the chassis unit 1 to be inserted into the receiving space 8 through the opening 80 by the action of the sliding component 2. After the rear end 10b of the chassis unit 1 is inserted into the receiving space 8 through the opening 80, the tail end 110 of the guide groove 11 moves toward the positioning component 3. Since the positioning component 3 is a positioning roller 30 with the axis A1 parallel to the second direction (i.e., the Z-axis direction), when the guide groove 11 moves relative to the positioning component 3 along the first direction (i.e., parallel to the X-axis direction), the positioning roller 30 can roll relative to the guide groove 11 to simultaneously achieve the functions of saving effort and limiting position, so that the chassis unit 1 can be smoothly placed into or removed from the receiving space 8 on the chassis device 9, avoiding damage or scratches to the side wall of the chassis unit 1 and the inner wall of the receiving space 8.

[0078] In this embodiment, the hook ends 41 of the handle assembly 4 are also arranged in pairs, spatially opposite to the guide grooves 11 of the chassis unit 1 and the positioning components 3 on the top 80a and bottom 80b of the receiving space 8. The following description is only an example of a single hook end 41 corresponding to a single guide groove 11 and a single positioning component 3, and is not intended to limit the invention. In this embodiment, when the guide groove 11 moves relative to the positioning component 3 along the first direction (i.e., the direction parallel to the X-axis), the handle assembly 4 is pre-rotated to the first position (e.g., Figure 7 As shown), the positioning component 3 is aligned with the tail end 110 of the guide groove 11 and the opening end 401 of the arc-shaped engagement groove 40. When the tail end 110 of the guide groove 11 approaches the positioning component 3, the handle component 4 engages with the positioning component 3 through the arc-shaped engagement groove 40, initiating the rotation of the handle component 4. Figure 8 As shown. The arc-shaped engagement groove 40 engages with the positioning component 3 until the positioning component 3 is limited to the tail end 110 of the guide groove 11 and engages with the tail end 402 of the arc-shaped engagement groove 40. The handle component 4 then rotates to the second position (as shown). Figure 9 (As shown).

[0079] In this embodiment, when the handle assembly 4 is rotated to the second position, the positioning assembly 3 is positioned at the tail end 110 of the guide groove 11 and engages with the tail end 402 of the arc-shaped engagement groove 40. Thus, the chassis unit 1 can be locked within the receiving space 8, and the gripping end 42 of the handle assembly 4 is retracted to the front end 10a of the chassis unit 1.

[0080] In this embodiment, the width W of the arc-shaped engagement groove 40 is greater than the diameter D of the positioning component 3, and it gradually narrows from the opening end 401 to the tail end 402. During the process of the handle component 4 rotating from the first position to the second position, the handle component 4 will maintain engagement with the positioning component 3 through the arc-shaped engagement groove 40. In this embodiment, the arc-shaped engagement groove 40 also includes a stickpoint 44 disposed at the tail end 402 of the arc-shaped engagement groove 40. The stickpoint 44 engages with the positioning component 3 when the chassis unit 1 is fully accommodated in the receiving space 8, thereby ensuring that the chassis unit 1 is correctly accommodated in the receiving space 8.

[0081] In this embodiment, the guide groove 11 extends from the rear end 10b of the chassis unit 1 toward the front end 10a along a first direction (i.e., parallel to the X-axis), but does not penetrate the front end 10a. In this embodiment, the handle assembly 4 is mounted on the chassis unit 1 via a pivot 43, such as a ball bearing, located between the tail end 110 of the guide groove 11 and the front end 10a of the chassis unit 1.

[0082] In this embodiment, when the handle assembly 4 rotates or swings, the arc-shaped engagement groove 40 and the guide groove 11 at least partially intersect in the second direction (i.e., the Z-axis direction), and the intersection can be used to limit the positioning assembly 3. In this embodiment, the hook end 41 is located inside the chassis unit 1, and the grip end 42 protrudes from the front end 10a of the chassis unit 1 through the front opening 12 adjacent to the top 10c and bottom 10d. The grip end 42 is connected along the second direction (i.e., the Z-axis direction) to facilitate the user's force operation.

[0083] In this embodiment, when the user wants to remove the chassis unit 1 from the receiving space 8, they can grasp the grip end 42 of the handle assembly 4 and pull it outward. At this time, the grip end 42 of the handle assembly 4 is forcefully extended outward from the front end 10a of the chassis unit 1, causing the positioning component 3 to disengage from the locking point 44 and move relative to the arc-shaped engagement groove 40, driving the handle assembly 4 from the second position to the first position. The positioning component 3 is confined to the guide groove 11 and the opening end 401 of the arc-shaped engagement groove 40, allowing the chassis unit 1 to be moved out of the receiving space 8 through the opening 80. In other words, the handle assembly 4, pivotally connected to the front end 10a of the chassis unit 1, can also cooperate with the positioning component 3 when the chassis unit 1 is placed into or removed from the receiving space 8. The arc-shaped engagement groove 40 and the positioning component 3 positioned in the guide groove 11 maintain engagement with each other, causing the handle assembly 4 to retract or extend the grip end 42, which is convenient for the user to operate and achieves the efficiency of saving effort.

Figure 11 This is a schematic diagram showing the structure of the chassis unit part detached from the receiving space in the chassis device of the second embodiment of the present invention. Figure 12 This is a side view showing the chassis unit being placed into or removed from the receiving space in the chassis device according to the second embodiment of the present invention. Figure 13 This is a rear view showing the chassis unit being placed into or removed from the receiving space in the chassis device according to the second embodiment of the present invention. Figure 14 for Figure 13 A magnified view of the central region P3. Figure 15 for Figure 13 Enlarged view of region P4. In this embodiment, the structures of the chassis assembly 9a, the receiving space 8a, and the chassis unit 1a are generally similar to those of... Figures 1 to 9 The chassis assembly 9, the housing space 8, and the chassis unit 1 shown all use the same component designations to represent the same components, structures, and functions, and will not be described further here. (See reference) Figures 7 to 15In this embodiment, the sliding component 2a of the chassis device 9a includes a plurality of support rollers 21. The plurality of support rollers 21 are arranged along a first direction and are paired on two opposite sides of the receiving space 8a, adjacent to the bottom 80b of the receiving space 8a. Preferably, the plurality of support rollers 21 are further paired on two opposite sides of the positioning component 3. For example, the plurality of support rollers 21 are arranged symmetrically with respect to the positioning component 3, and the axis A2 of the plurality of support rollers 21 is parallel to a third direction (i.e., the Y-axis direction), and the first direction is perpendicular to the third direction. In addition, the chassis unit 1a includes a pair of recesses 13 disposed on two opposite sides of the bottom 10d. The pair of recesses 13 are spatially relative to the plurality of support rollers 21. When the rear end 10b of the chassis unit 1a is inserted into or removed from the receiving space 8a through the opening 80 along the first direction (i.e., parallel to the X-axis direction), the plurality of support rollers 21 support the bottom 10d of the chassis unit 1a through the pair of recesses 13.

[0085] In this embodiment, multiple support rollers 21 respectively contact the bottom 80b of the constant-abutment receiving space 8a and the bottom 10d of the chassis unit 1a. When the guide grooves 11 of the top 10c and bottom 10d of the chassis unit 1a align their open ends with the positioning component 3, the chassis unit 1a is allowed to be placed back into the receiving space 8a through the opening 80 by the action of the sliding component 2a. During the process of the rear end 10b of the chassis unit 1a being placed into the receiving space 8a through the opening 80, the multiple support rollers 21 of the sliding component 2a maintain rolling relative to the bottom 10d of the chassis unit 1a, providing a labor-saving function. Since the positioning component 3 is also a positioning roller 30 structure, during the process of the rear end 10b of the chassis unit 1a being placed into the receiving space 8a through the opening 80, the positioning roller 30 can roll relative to the guide groove 11 to simultaneously achieve the functions of labor saving and limiting positioning. Therefore, the chassis unit 1a can be smoothly placed into or removed from the receiving space 8a on the chassis device 9a, avoiding damage or scratches to the side wall of the chassis unit 1a and the inner wall of the receiving space 8a.

[0086] In this embodiment, the operating method of the handle assembly 4 in conjunction with the positioning assembly 3 when the chassis unit 1a is placed into or removed from the receiving space 8a is the same as in the previous embodiment, and will not be described again here. It is worth noting that in this embodiment, when the user operates the handle assembly 4 to place the chassis unit 1a into or remove it from the receiving space 8a, the multiple support rollers 21 of the sliding assembly 2a and the positioning rollers 30 of the positioning assembly 3 can all maintain rolling between the chassis unit 1a and the receiving space 8a, achieving the functions of saving effort and limiting movement, so that the chassis unit 1a can be smoothly placed into or removed from the receiving space 8a on the chassis device 9a, avoiding collisions or scratches with the inner wall of the receiving space 8a. Of course, the number and arrangement of the aforementioned ball bearings 20, support rollers 21 and positioning rollers 30 can be adjusted according to actual application requirements, and the present invention is not limited thereto and will not be described again.

[0087] In summary, this invention provides a chassis assembly for server rooms. By using a sliding component and a positioning component positioned between the chassis unit and the receiving space, it achieves both labor-saving and positioning effects, effectively reducing the force applied when installing the chassis unit into the receiving space and preventing bumps / scratches. The sliding component, constructed between the bottom of the receiving space and the chassis unit using ball bearings and rollers, provides sufficient support and achieves labor-saving functionality. Furthermore, the positioning component, consisting of rollers at the top and bottom of the receiving space and guide grooves on the chassis unit, simultaneously achieves labor-saving and limiting functions, allowing the chassis unit to be smoothly placed into or removed from the receiving space of the chassis assembly, preventing bumps or scratches against the inner wall of the receiving space. On the other hand, the handle assembly pivotally connected to the front end of the chassis unit works in conjunction with the positioning component when the chassis unit is placed into or removed from the receiving space. Through an arc-shaped meshing groove, it engages with the positioning component positioned in the guide groove, causing the handle assembly to retract or extend its gripping end, facilitating user operation and achieving labor-saving efficiency.
