The mounting elements 50 are, for example, hard disks, display cards, cable covers, cooling radiators or fans, and can be detachably mounted on at least a portion of the mounting rods 21 according to user needs and the configuration in the chassis.

[0058] In this embodiment, the distance between any two adjacent first fixing structures 211 is 10 mm, but the present invention is not limited thereto. In other embodiments, the distance between any two adjacent first fixing structures can also be adjusted according to the needs of the user and the configuration in the chassis.

[0059] In this embodiment, the first fixing structures 211 are screw holes, and the second fixing structures 23 are screws, so that the tray 22 is fixed to the mounting rods 21 by screwing the second fixing structures 23 and the first fixing structures 211, but the present invention is not limited thereto. In other embodiments, the first fixing structures and the second fixing structures may also be other fixing members, so that the tray is fixed to the mounting rods by other fixing methods.

[0060] In this embodiment, since the mutually parallel mounting rods 21 each have a plurality of first fixing structures 211, and the first fixing structures 211 are respectively arranged along the long axis direction of the mounting rods 21, the user can install the tray 22 at any position on the mounting rods 21 according to his own needs and the configuration in the chassis. For example, the user can install the tray 22 at the rightmost end of the mounting rod 21, the middle section of the mounting rod 21, or the leftmost end of the mounting rod 21.

In detail, the electronic device 10B of this embodiment is, for example, disposed at a case back plate (not shown) away from the case in a case. For example, the tray 22 and the motherboard 30 are disposed between the mounting elements 50. In addition, compared with the electronic device 10 of the first embodiment, the electronic device 10B is disposed approximately upside down.

[0066] See also Figure 7 . Figure 7 The electronic device 10C of this embodiment is similar to the electronic device 10 of the first embodiment, so the differences between this embodiment and the first embodiment will be described below, and the similarities will not be repeated.

[0067] In this embodiment, the electronic device 10C can adjust the position of the mounting rods 21 in the case according to the needs of the user and the configuration in the case (not shown), and adjust the position of the tray 22 on the mounting rods 21. In detail, the electronic device 10C of this embodiment is, for example, disposed in a case near the case back plate (not shown) of the case. For example, the tray 22 and the motherboard 30 are disposed on one side of the mounting elements 50. In addition, the electronic device 10C is disposed approximately upside down compared to the electronic device 10 of the first embodiment.

[0068] See also Figure 8 . Figure 8 The electronic device 10D of this embodiment is similar to the electronic device 10 of the first embodiment, so the differences between this embodiment and the first embodiment will be described below, and the similarities will not be repeated.

[0069] In this embodiment, the electronic device 10D can be equipped with a tray 22D and a motherboard 30D according to the needs of the user. In detail, the number of trays 22D and the number of motherboards 30D of the electronic device 10D are, for example, two. The two trays 22D can be detachably disposed on the mounting rods 21, and the two trays 22D are arranged side by side. The two motherboards 30D can be detachably disposed on the two trays 22D respectively.

[0070] In this embodiment, the number of the trays 22D and the number of the motherboards 30D are two, but the present invention is not limited thereto. In other embodiments, the number of the trays and the number of the motherboards can also be more than three.

[0071] See also Figures 9 to 11 . Fig. 9 It is a three-dimensional schematic diagram of an electronic device according to a sixth embodiment of the present invention. Fig.10 for Fig. 9 A partially enlarged exploded schematic diagram of an electronic device omitting a mainboard. Fig.11 for Fig. 9 A partially enlarged cross-sectional schematic diagram of an electronic device with a mainboard omitted.

[0072] The electronic device 10E of this embodiment includes a mounting assembly 20E and a motherboard 30. The mounting assembly 20E includes a plurality of mounting rods 21 having a plurality of first fixing structures 211E, a tray 22, a plurality of second fixing structures 23E, and a plurality of pivoting members 24. The first fixing structures 211E are, for example, snap holes, and the second fixing structures 23E are, for example, flexible snap members. The tray 22 is detachably mounted on the mounting rods 21, and the motherboard 30 is detachably mounted on the tray 22. One side of the second fixing structures 23E is rotatably disposed on the tray 22.

[0073] In detail, each second fixing structure 23E includes a first plate 231, a second plate 232, a third plate 233 and a fourth plate 234. One side of the first plate 231 is pivoted to the tray 22, for example, via a pivot member 24. Two opposite sides of the second plate 232 are respectively connected to the other side of the first plate 231 and the third plate 233, so that the first plate 231, the second plate 232 and the third plate 233 together surround an assembly slot S.

[0074] The third plate 233 has an elastic arm 2331 and a second buckle structure 2332. The second buckle structure 2332 is, for example, a buckle protrusion, and matches the first fixed structure 211E. The second buckle structure 2332 is located on the side of the elastic arm 2331 close to the assembly slot S. In other words, the second buckle structure 2332 protrudes toward the first plate 231. At least part of these mounting rods 21 are respectively used to at least partially install in these assembly slots S of these second fixed structures 23E, so that these second buckle structures 2332 can be selectively buckled in these first fixed structures 211E.

[0075] The fourth plate 234 is connected to a side of the third plate 233 away from the second plate 232 and protrudes in a direction away from the second buckle structure 2332. The fourth plate 234 is used for user operation to facilitate rotating the second fixing structure 23E or to facilitate pulling to release the buckle between the second buckle structure 2332 and the first fixing structure 211E.

[0076] In this embodiment, since the tray 22 of the electronic device 10E is provided with a second fixing structure 23E such as a flexible buckle, the user only needs to rotate the second fixing structure 23E and make the second buckle structure 2332 of the second fixing structure 23E buckle with the first fixing structure 211E of the mounting rod 21 to fix the tray 22 to the mounting rod 21. In this way, the convenience of installing the tray 22 can be further improved.

[0077] In this embodiment, the first fixing structures 211E are snap holes, and the second snap structures 2332 are snap bumps, but the present invention is not limited thereto. In other embodiments, the first snap structures and the second snap structures may also be reversed in shape. In other words, the first snap structures may also be snap bumps, and the second snap structures may also be snap holes.

[0078] In this embodiment, one side of the first plate 231 is pivotally mounted on the tray 22 via the pivoting member 24, but the present invention is not limited thereto. In other embodiments, one side of the first plate 231 may also be rotatably mounted on the tray in other ways.

[0079] See also Figures 12 to 17 . Fig.12 for Fig. 9 A partially enlarged three-dimensional schematic diagram of an electronic device in which a second fixing structure has not yet been snapped onto a mounting rod. Fig.13 for Fig. 9 A partially enlarged three-dimensional schematic diagram of a second fixing structure in an electronic device about to be snapped onto a mounting rod.

Fig.17 for Fig.16 A partially enlarged cross-sectional schematic diagram.

[0080] In this embodiment, when the user selects Fig. 9 The motherboard 30 is to be installed in a position in a housing (not shown) and is to be installed as follows Fig. 9 When the motherboard is 30, first, Fig.12 As shown, the tray 22 is placed on the mounting rod 21, and the position of the tray 22 corresponds to the selected installation position. At this time, the second fixing structure 23E has not yet been snapped onto the mounting rod 21. Figures 13 to 15 As shown, the second fixing structure 23E is rotated along direction A. At this time, the second buckle structure 2332 interferes with the mounting rod 21, so that the elastic arm portion 2331 is deformed along direction B and stores elastic force. Fig.16 and Fig.17 As shown, the second fixing structure 23E is rotated along direction A to make the mounting rod 21 at least partially located in the assembly slot S. At this time, the second buckle structure 2332 and the mounting rod 21 are freed from interference, so that the elastic arm portion 2331 releases the elastic force in the opposite direction of direction B and resets, so that the second buckle structure 2332 is buckled with the first fixing structure 211E. In this way, the tray 22 can be fixed to the mounting rod 21 through the second fixing structure 23E, and the motherboard 30 can be installed.

[0081] On the contrary, when the user wants to replace the tray 22 and Fig. 9 When the motherboard 30 is installed in the desired position, first, the fourth plate 234 of the second fixing structure 23E is pulled along direction B to release the second buckle structure 2332 from the first fixing structure 211E. Then, the second fixing structure 23E is rotated in the opposite direction of direction A. In this way, the tray 22 can be removed from the mounting rod 21, and the tray 22 can be replaced with the first fixing structure 211E. Fig. 9 The installation position of the main board 30.

[0082] According to the electronic device and the mounting assembly of the above-mentioned embodiment, since the mutually parallel mounting rods each have a plurality of first fixing structures, and the first fixing structures are arranged along the long axis direction of the mounting rods, the user can install the tray at any position on the mounting rods according to his own needs and the configuration in the chassis. For example, the user can install the tray at the rightmost end of the mounting rod, the middle section of the mounting rod, or the leftmost end of the mounting rod. In this way, the flexibility and convenience of the tray in installation can be improved.

[0083] Similarly, the mounting element can also be installed at any position on the mounting rod according to the user's needs and the configuration in the chassis through the above structure. In this way, the flexibility and convenience of the mounting element in installation can also be improved.

[0084] In addition, since the tray of the electronic device is provided with a second fixing structure such as a flexible buckle, the user can fix the tray to the mounting rod by simply rotating the second fixing structure and buckling the second buckle structure of the second fixing structure to the first fixing structure of the mounting rod. In this way, the convenience of installing the tray can be further improved.

[0085] Although the present invention is disclosed as above with the aforementioned embodiments, they are not used to limit the present invention. Anyone familiar with similar skills can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be based on the scope defined in the attached claims.
