Figure 3 is a side view showing the chassis unit being placed into or removed from the receiving space in the chassis device of the first embodiment of this invention. Figure 4 is a rear view showing the chassis unit being placed into or removed from the receiving space in the chassis device of the first embodiment of this invention. Figure 5 is an enlarged view of region P1 in Figure 4. Figure 6 is an enlarged view of region P2 in Figure 4. Figure 7 is a schematic diagram showing the handle assembly rotated to a first position. Figure 8 is a schematic diagram showing the transition state of the handle assembly rotating from the first position to a second position. Figure 9 is a schematic diagram showing the handle assembly rotated to the second position. Referring to Figures 1 to 9, this invention provides a chassis device 9 for a server room. The chassis device 9 includes multiple receiving spaces 8 with the same structure arranged in a single row or multiple rows, each receiving space 8 allowing the installation of one chassis unit 1. In this embodiment, the chassis device 9, in addition to including at least one receiving space 8 and at least one chassis unit 1 for mating installation, also includes a sliding component 2, a positioning component 3, and a handle component 4, to achieve the effect of effort-saving and positioning 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 of the chassis device 9 paired with a single chassis unit 1, and is not intended to limit this 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, for example, includes a plurality of ball bearings 20 disposed along the first direction (i.e., parallel to the X-axis) between the bottom of the receiving space 8 and the bottom 10d of the chassis unit 1, allowing the chassis unit 1 to slide relative to the receiving space 8 along the first direction (i.e., parallel to the X-axis) via the sliding component 2, and supporting the chassis unit 1. In this embodiment, the positioning component 3 is disposed within the accommodating space 8, wherein the chassis unit 1 further includes a guide groove 11 disposed on the chassis unit 1 along a first direction (i.e., parallel to the X-axis direction). The guide groove 11 is spatially relative to the positioning component 3. When the chassis unit 1 is inserted into or removed from the accommodating 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 hook end 41 and a grip end 42 that are opposite each other. The hook end 41 is spatially positioned relative to the positioning component 3 and the guide groove 11. The grip end 42 protrudes from the front end 10a of the chassis unit 1. When the handle assembly 4 is rotated to a first position (as shown in Figure 7), 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 (as shown in Figure 9).

[0041] 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 arranged 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 arranged parallel to the second direction (i.e., the Z-axis direction) and is spatially relative to the guide grooves 11 of the top 10c and bottom 10d of the chassis unit 1.

[0042] In this embodiment, the sliding component 2 includes a plurality of balls 20, which are disposed at the bottom 10d of the chassis unit 1 along a first direction (i.e., parallel to the X-axis direction) and 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, this embodiment is not limited to this. 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 direction), 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, this embodiment is not limited to this.

[0043] 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 achieve both labor-saving and limiting functions, 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.

[0044] 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 this embodiment. 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 (as shown in Figure 7), allowing the positioning component 3 to align 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 assembly 4 will engage with the positioning component 3 through the arc-shaped engagement groove 40, and begin to rotate, as shown in Figure 8. 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, at which point the handle component 4 rotates to the second position (as shown in Figure 9).

[0045] 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. In this way, the chassis unit 1 can be locked in 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.

[0046] 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 further includes a stick point 44 disposed at the tail end 402 of the arc-shaped engagement groove 40. The stick point 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.

[0047] 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.

[0048] In this embodiment, when the handle assembly 4 rotates or swings, the arc-shaped engagement groove 40 and the guide groove 11 are maintained to intersect at least partially in the second direction (i.e., the Z-axis direction), and the positioning assembly 3 can be positioned therein at the intersection. 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.

[0049] 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.

[0050] Figure 10 is a schematic diagram showing the chassis unit fully housed in the receiving space in the chassis assembly of the second embodiment of this invention. Figure 11 is a schematic diagram showing the chassis unit partially detached from the receiving space in the chassis assembly of the second embodiment of this invention. Figure 12 is a side view showing the chassis unit being placed into or removed from the receiving space in the chassis assembly of the second embodiment of this invention. Figure 13 is a rear view showing the chassis unit being placed into or removed from the receiving space in the chassis assembly of the second embodiment of this invention. Figure 14 is an enlarged view of region P3 in Figure 13. Figure 15 is an enlarged view of region P4 in Figure 13. 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 the chassis assembly 9, the receiving space 8, and the chassis unit 1 shown in Figures 1 to 9, and the same component numbers represent the same components, structures, and functions, which will not be described again here. Refer to Figures 7 to 15. In 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.

[0051] 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. In this way, 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.

[0052] 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 changed according to actual application requirements, and this case is not limited to this and will not be described again.

[0053] In summary, this invention provides a server rack assembly for server rooms. By using a sliding component and a positioning component positioned between the rack unit and the receiving space, it achieves both labor-saving and positioning effects, effectively reducing the force required to install the rack unit into the receiving space and preventing bumps / scratches. The sliding component, constructed between the bottom of the receiving space and the rack 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 rack unit, simultaneously achieves labor-saving and limiting functions, allowing the rack unit to be smoothly placed into or removed from the receiving space of the rack 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 of the rack unit works in conjunction with the positioning component when the rack 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 grip, facilitating user operation and achieving labor-saving efficiency.

[0054] This case can be modified in various ways by a person skilled in this technology, but all of them are still within the scope of the patent application.
