FIG. 9 is a schematic diagram showing a state in which the handle part has rotated to the second position. Referring to FIGS. 1 to 9, the present invention provides a chassis device 9 for use in a server room. The chassis device 9 includes multiple accommodating spaces 8 of the same structure, arranged in one or more rows, each capable of mounting one chassis unit 1. In this embodiment, the chassis device 9 includes a combination of at least one accommodating space 8 and at least one chassis unit 1, and further includes a sliding component 2, a positioning component 3, and a handle component 4. This reduces the labor required to mount the chassis unit 1 in the accommodating space 8 and improves positioning, effectively reducing the force required during mounting and preventing damage or scratches. The following description will be given using an example of a combination of one accommodating space 8 and one chassis unit 1 in the chassis device 9, but the present invention is not limited thereto. In this embodiment, the accommodating space 8 includes an opening 80 facing a first direction, for example, parallel to the X-axis direction. The rear end 10b of the chassis unit 1 is inserted into or removed from the accommodating space 8 through the opening 80 in the first direction (i.e., parallel to the X-axis direction).The sliding element 2 includes, for example, a plurality of balls 20 provided between the bottom of the accommodating space 8 and the bottom 10d of the chassis unit 1 along a first direction (i.e., a direction parallel to the X-axis direction), allowing the chassis unit 1 to slide in the first direction (i.e., a direction parallel to the X-axis direction) relative to the accommodating space 8 via the sliding element 2 and supporting the chassis unit 1. In this embodiment, the positioning element 3 is provided in the accommodating space 8, and the chassis unit 1 further includes a guide groove 11 provided in the chassis unit 1 along the first direction (i.e., a direction parallel to the X-axis direction), the guide groove 11 spatially corresponding to the positioning element 3, and when the chassis unit 1 is inserted into or removed from the accommodating space 8 through the opening 80 in the first direction (i.e., a direction parallel to the X-axis direction), the positioning element 3 is restricted within the guide groove 11. The handle part 4 is pivotally mounted on the front end 10a of the chassis unit 1 and has a hook 41 and a grip 42 on opposite sides, the hook 41 spatially corresponds to the positioning part 3 and the guide groove 11, and the grip 42 protrudes from the front end 10a of the chassis unit 1. When the handle part 4 is rotated to the first position (Figure 7), the arc-shaped engagement groove 40 of the hook 41 is aligned with the guide groove 11 and the positioning part 3, and the arc-shaped engagement groove 40 engages with the positioning part 3, thereby rotating the handle part 4 to the second position (Figure 9).

[0027] In this embodiment, the positioning component 3 includes a plurality of positioning rollers 30 that are arranged at intervals along a first direction (i.e., a direction parallel to the X-axis direction) and whose axes A1 are parallel to a second direction (i.e., the Z-axis direction) that is perpendicular to the first direction. The positioning component 3 also includes at least one pair of positioning rollers 30 that are provided in pairs, each pair being provided midway between the top 80a and the bottom 80b of the accommodation space 8. The at least one pair of positioning rollers 30 is provided such that its axis A1 is parallel to the second direction (i.e., the Z-axis direction) and spatially corresponds to the guide grooves 11 on the top 10c and the bottom 10d of the chassis unit 1.

[0028] In this embodiment, the sliding element 2 includes a plurality of balls 20 arranged on the bottom 10d of the chassis unit 1 along a first direction (i.e., a direction parallel to the X-axis direction), and the plurality of balls 20 spatially correspond to the bottom 80b of the accommodating space 8. Preferably, the plurality of balls 20 are arranged in pairs on opposite sides of the positioning element 3. For example, the plurality of balls 20 are arranged symmetrically with respect to the positioning element 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 accommodating space 8 through the opening 80 in the first direction (i.e., a direction parallel to the X-axis direction), the plurality of balls 20 abut against the bottom 80b of the accommodating space 8 to support the chassis unit 1, thereby reducing the contact area between the chassis unit 1 and the accommodating space 8 and optimizing the displacement of the chassis unit 1 relative to the accommodating space 8. Of course, the present invention is not limited thereto.

[0029] In this embodiment, when the opening ends of the guide grooves 11 on the top and bottom portions 10c and 10c of the chassis unit 1 are aligned with the positioning component 3, the chassis unit 1 can be inserted into the accommodating 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 accommodating space 8 through the opening 80, the tail end 110 of the guide groove 11 moves toward the positioning component 3. The positioning component 3 includes a positioning roller 30 whose axis A1 is parallel to the second direction (i.e., the Z-axis direction). When the guide groove 11 moves in the first direction (i.e., the direction parallel to the X-axis direction) relative to the positioning component 3, the positioning roller 30 rolls in the guide groove 11, thereby achieving both labor-saving and position limiting functions. This allows the chassis unit 1 to be smoothly inserted into and removed from the accommodating space 8 for the chassis device 9 and prevents damage or scratches caused by collisions between the side walls of the chassis unit 1 and the inner walls of the accommodating space 8.

[0030] In this embodiment, the hooks 41 of the handle part 4 are also provided in pairs and spatially correspond to the paired guide grooves 11 of the chassis unit 1 and the positioning parts 3 on the top 80a and bottom 80b of the receiving space 8. In the following description, one hook 41 corresponds to one guide groove 11 and one positioning part 3, but the present invention is not limited to this. In this embodiment, when the guide groove 11 moves along the first direction (i.e., the direction parallel to the X-axis direction) relative to the positioning part 3, the handle part 4 is pre-rotated to the first position ( FIG. 7 ), and the positioning part 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 part 3, the handle part 4 is engaged with the arc-shaped engagement groove 40, causing the handle part 4 to rotate as shown in FIG. 8 . When the arc-shaped engagement groove 40 engages with the positioning part 3, and the positioning part 3 is restricted 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 part 4 rotates to the second position (Figure 9).

[0031] In this embodiment, when the handle part 4 is rotated to the second position, the positioning part 3 is restricted by the tail end 110 of the guide groove 11 and engaged with the tail end 402 of the arc-shaped engagement groove 40. This locks the chassis unit 1 in the accommodating space 8, and the grip 42 of the handle part 4 can be retracted to the front end 10a of the chassis unit 1.

[0032] In this embodiment, the width W of the arc-shaped engaging groove 40 is greater than the diameter D of the positioning component 3 and gradually decreases from the opening end 401 to the tail end 402, so that when the handle component 4 rotates from the first position to the second position, the handle component 4 maintains engagement with the positioning component 3 through the arc-shaped engaging groove 40. In addition, in this embodiment, the arc-shaped engaging groove 40 further includes a stuck point 44 located at the tail end 402 of the arc-shaped engaging groove 40, so that when the chassis unit 1 is fully accommodated in the accommodating space 8, the stuck point 44 engages with the positioning component 3, ensuring that the chassis unit 1 is properly accommodated in the accommodating space 8.

[0033] In this embodiment, the guide groove 11 extends from the rear end 10b to the front end 10a of the chassis unit 1 along the first direction (i.e., the direction parallel to the X-axis direction), but does not penetrate the front end 10a. In this embodiment, the handle component 4 is disposed on the chassis unit 1 via a pivot member 43 such as a ball bearing, and the pivot member 43 is located between the rear end 110 of the guide groove 11 and the front end 10a of the chassis unit 1.

[0034] In this embodiment, when the handle part 4 is rotated or swung, 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). The intersection is used to restrict the positioning part 3 inside. In this embodiment, the hook 41 is located within the chassis unit 1, and the grip 42 protrudes from the front end 10a of the chassis unit 1 through the front end opening 12 adjacent to the top part 10c and the bottom part 10d. The grip 42 is connected along the second direction (i.e., the Z-axis direction) to facilitate user operation.

[0035] In this embodiment, when a user attempts to remove the chassis unit 1 from the storage space 8, the user can hold the grip 42 of the handle part 4 and pull it outward. At this time, the grip 42 of the handle part 4 receives a force and protrudes outward from the front end 10a of the chassis unit 1. At the same time, the positioning part 3 is released from the locking point 44 and moves relative to the arc-shaped engaging groove 40. As a result, the handle part 4 is rotated from the second position to the first position, and the positioning part 3 is restricted by the guide groove 11 and the opening end 401 of the arc-shaped engaging groove 40. This allows the chassis unit 1 to be removed from the storage space 8 through the opening 80. In other words, the handle part 4 pivotally connected to the front end 10a of the chassis unit 1 can cooperate with the positioning part 3 when the chassis unit 1 is inserted into or removed from the storage space 8, and by maintaining the engagement between the arc-shaped engagement groove 40 and the positioning part 3 positioned within the guide groove 11, the handle part 4 can be driven to retract or extend the grip 42, making operation convenient for the user and reducing labor.

FIG. 11 is a structural schematic diagram of a chassis device according to the second embodiment of the present invention, showing a state in which a part of the chassis unit is detached from the accommodation space. FIG. 12 is a side view of a chassis device according to the second embodiment of the present invention, showing a state in which a chassis unit is being inserted into or removed from the accommodation space. FIG. 13 is a rear view of a chassis device according to the second embodiment of the present invention, showing a state in which a chassis unit is being inserted into or removed from the accommodation space. FIG. 14 is an enlarged view of area P3 in FIG. 13. FIG. 15 is an enlarged view of area P4 in FIG. 13. In this embodiment, the chassis device 9a, accommodation space 8a, and chassis unit 1a have the same structures as the chassis device 9, accommodation space 8, and chassis unit 1 shown in FIGS. 1 to 9. The same reference numerals denote the same elements, structures, and functions, and their descriptions will not be repeated here. See FIGS. 7 to 15. In this embodiment, a sliding component 2a of the chassis device 9a includes a plurality of support rollers 21. The support rollers 21 are arranged along the first direction and are disposed in pairs on opposite sides of the storage space 8a, adjacent to the bottom 80b of the storage space 8a. Preferably, the support rollers 21 are disposed in pairs on opposite sides of the positioning component 3. For example, the support rollers 21 are disposed symmetrically with respect to the positioning component 3, and the axes A2 of the support rollers 21 are parallel to a third direction (i.e., the Y-axis direction) perpendicular to the first direction. The chassis unit 1a has a pair of recesses 13 disposed on opposite sides of the bottom 10d. The pair of recesses 13 spatially correspond to the support rollers 21. When the rear end 10b of the chassis unit 1a is inserted into or removed from the storage space 8a through the opening 80 in the first direction (i.e., the direction parallel to the X-axis direction), the support rollers 21 support the bottom 10d of the chassis unit 1a via the pair of recesses 13.

[0037] In this embodiment, the plurality of support rollers 21 are in contact with and abut against the bottom 80b of the accommodating space 8a and the bottom 10d of the chassis unit 1a, respectively. When the opening ends of the guide grooves 11 on the top 10c and bottom 10d of the chassis unit 1a are aligned with the positioning member 3, the chassis unit 1a can be inserted into the accommodating space 8a through the opening 80 by the action of the sliding member 2a. As the rear end 10b of the chassis unit 1a is inserted into the accommodating space 8a through the opening 80, the plurality of support rollers 21 of the sliding member 2a roll against the bottom 10d of the chassis unit 1a, thereby achieving a labor-saving function. The positioning member 3 includes a positioning roller 30 structure. As the rear end 10b of the chassis unit 1a is inserted into the accommodating space 8a through the opening 80, the positioning roller 30 rolls against the guide grooves 11, thereby simultaneously achieving labor-saving and position-limiting functions. This allows the chassis unit 1a to be smoothly inserted into and removed from the accommodation space 8a of the chassis device 9a, and prevents damage and scratches caused by collision between the side walls of the chassis unit 1a and the inner walls of the accommodation space 8a.

[0038] In this embodiment, the operation of the handle component 4 when inserting or removing the chassis unit 1a into or from the storage space 8a is the same as in the previous embodiment, and therefore a description thereof will not be repeated here. In particular, in this embodiment, when a user operates the handle component 4 to insert or remove the chassis unit 1a into or from the storage space 8a, the support rollers 21a of the sliding component 2a and the positioning rollers 30 of the positioning component 3 all roll between the chassis unit 1a and the storage space 8a, thereby simultaneously achieving labor-saving and position-limiting functions. This allows the chassis unit 1a to be smoothly inserted or removed into or from the storage space 8a of the chassis device 9a, and prevents damage or scratches caused by collisions between the side walls of the chassis unit 1a and the inner walls of the storage space 8a. The number and arrangement of the balls 20, support rollers 21, and positioning rollers 30 are not limited to those described above and can be adjusted according to actual applications, and therefore a description thereof will not be repeated here.

[0039] In summary, the present invention provides a chassis device for use in a server room. By disposing sliding and positioning components between the chassis unit and the storage space, it achieves labor-saving and positioning effects, effectively reducing the force required to install the chassis unit in the storage space and avoiding damage and scratches caused by collisions. The sliding components, which use balls and rollers to construct the sliding components between the bottom of the storage space and the chassis unit, provide sufficient support and reduce labor. Furthermore, the positioning components, which cooperate with rollers located at the top and bottom of the storage space and guide grooves located on the chassis unit, achieve both labor-saving and position-limiting functions. This allows the chassis unit to be smoothly inserted and removed from the storage space of the chassis device and prevents damage and scratches caused by collisions with the inner wall of the storage space. Meanwhile, the handle component pivotally mounted on the front end of the chassis unit cooperates with the positioning component when inserting and removing the chassis unit into and from the storage space. The arc-shaped engagement groove engages with the positioning component positioned in the guide groove, driving the handle component to advance and retreat the grip, thereby facilitating user operation and reducing labor.
