[0025] As shown in FIGS. 1 and 2, the electronic device 1 comprises a casing 10 and a tray 12. It should be noted that the casing 10 shown in FIG. 1 is only a part of a complete casing of the electronic device 1. In practical applications, the electronic device 1 may be a server or other electronic devices equipped with the tray 12. In this embodiment, the casing 10 may comprise a first electrical connector 100 and a second electrical connector 102, as shown in FIG. 3. For example, the first electrical connector 100 may be an electrical connector of a PCIe base board (PBB) module disposed in front of the casing 10, and the second electrical connector 102 may be an electrical connector of a power supply unit (PSU) disposed above the casing 10. However, the disclosure is not so limited. In general, the electronic device 1 may be further equipped with some necessary hardware and software components for specific purposes, such as a processor, a memory, a circuit board, a power supply, applications, a communication module, etc., and it depends on practical applications.

[0026] As shown in FIGS. 4 to 7, the tray 12 comprises a tray body 120, a handle 122, a first transmission mechanism 124, a second transmission mechanism 126, a third transmission mechanism 128, a third electrical connector 130 and a fourth electrical connector 132. The tray body 120 may be disposed in the casing 10 or removed from the casing 10, as shown in FIGS. 1 and 2. The first transmission mechanism 124 is configured to rotatably connect the handle 122 to the tray body 120. The second transmission mechanism 126 is disposed on the tray body 120 and connected to the first transmission mechanism 124. The third transmission mechanism 128 is disposed on the tray body 120 and corresponds to the second transmission mechanism 120. In this embodiment, the first transmission mechanism 124 may be disposed outside the tray body 120, and the second transmission mechanism 126 and the third transmission mechanism 128 may be disposed inside the tray body 120. The third electrical connector 130 is disposed on the tray body 120 and corresponds to the first electrical connector 100 of the casing 10. The fourth electrical connector 132 is disposed on the third transmission mechanism 128 and corresponds to the second electrical connector 102 of the casing 10. For example, a graphics processing unit (GPU) module (not shown) or other electronic modules may be fixed on the tray body 120 of the tray 12 and electrically connected to the third electrical connector 130 and the fourth electrical connector 132.

[0027] As shown in FIGS. 8 to 13, when the handle 122 rotates, the first transmission mechanism 124 drives the second transmission mechanism 126 to move along a first direction X and the second transmission mechanism 126 drives the third transmission mechanism 128 to move along a second direction Y perpendicular to the first direction X. When the handle 122 is located at a first position (as shown in FIGS. 8 and 9), the third electrical connector 130 of the tray 12 is separated from the first electrical connector 100 of the casing 10, and the fourth electrical connector 132 of the tray 12 is separated from the second electrical connector 102 of the casing 10. Thus, when the handle 122 is located at the first position, a user may put the tray body 120 of the tray 12 into the casing 10 or remove the tray body 120 of the tray 12 from the casing 10. When the handle 122 rotates from the first position toward a second position (as shown in FIGS. 10 and 11), the first transmission mechanism 124 drives the second transmission mechanism 126 to move along the first direction X, such that the third electrical connector 130 of the tray 12 is connected to the first electrical connector 100 of the casing 10. At this time, the third transmission mechanism 128 remains stationary, such that the fourth electrical connector 132 of the tray 12 is still separated from the second electrical connector 102 of the casing 10. Then, when the handle 122 rotates from the second position toward a third position (as shown in FIGS. 12 and 13), the first transmission mechanism 124 drives the second transmission mechanism 126 to move along the first direction X and the second transmission mechanism 126 drives the third transmission mechanism 128 to move along the second direction Y, such that the fourth electrical connector 132 of the tray 12 is connected to the second electrical connector 102 of the casing 10. On the other hand, when the user wants to disassemble the tray 12 from the casing 10, the user may first rotate the handle 122 from the third position toward the second position to separate the fourth electrical connector 132 of the tray 12 from the second electrical connector 102 of the casing 10, and then rotate the handle 122 from the second position toward the first position to separate the third electrical connector 130 of the tray 12 from the first electrical connector 100 of the casing 10. Accordingly, the user can conveniently and rapidly assemble and disassemble the tray 12.

[0028] As shown in FIG. 5, the first transmission mechanism 124 may comprise a driving member 1240, a support member 1242, a rotating member 1244, a first restraining member 1246 and a second restraining member 1248. The driving member 1240 is pivotally connected the tray body 120 and connected to the handle 122, such that the handle 122 can drive the driving member 1240 to rotate with respect to the tray body 120. The support member 1242 is connected to the driving member 1240, such that the support member 1242 can rotate along with the driving member 1240. The rotating member 1244 is pivotally connected to the tray body 120 and located between the driving member 1240 and the support member 1242. Furthermore, the driving portion 1240 may comprise a first restraining groove 12400, and the tray body 120 may comprise a second restraining groove 1200. The first restraining groove 12400 and the second restraining groove 1200 both are arc-shaped. The first restraining member 1246 passes through the first restraining groove 12400 to be fixed on the tray body 120, so as to restrain a rotating range of the driving member 1240. The second restraining member 1248 passes through the second restraining groove 1200 to be fixed on the rotating member 1244, so as to restrain a rotating range of the rotating member 1244.

[0029] In this embodiment, the support member 1242 may comprise a first slot 12420 and a second slot 12422, wherein the first slot 12420 is connected to the second slot 12422. The first slot 12420 and the second slot 12422 are connected to each other to be L-shaped. Furthermore, the rotating member 1244 may comprise a driving portion 12440. As shown in FIG. 8, when the handle 122 is located at the first position, the driving portion 12440 of the rotating member 1244 is located in the first slot 12420 of the support member 1242. Still further, the tray 12 may further comprise a lock member 134 disposed on the tray body 120. In this embodiment, the lock member 134 may be an elastic sheet and an end of the lock member 134 is fixed on the tray body 120. The lock member 134 may comprise an engaging portion 1340 and the driving member 1240 may comprise an engaging recess 12402. As shown in FIG. 8, when the handle 122 is located at the first position, the engaging portion 1340 engages with the engaging recess 12402 to lock the driving member 1240.

[0030] In this embodiment, the interior of the casing 10 may comprise a stop member 104 and an unlock portion 106, as shown in FIG. 2. Furthermore, the driving member 1240 may comprise a stop portion 12404. When the handle 122 is located at the first position and the tray 12 is pushed into the casing 10, the stop member 104 stops the stop portion 12404 to restrain the tray 12 from moving, as shown in FIGS. 1 and 8. When the tray 12 is pushed into the casing 10, the unlock portion 106 drives the lock member 134 to move toward an inside of the tray 12, such that the engaging portion 1340 disengages from the engaging recess 12402 to unlock the driving member 1240. At this time, the driving member 1240 can rotate with respect to the tray body 120.

[0031] Then, a user may rotate the handle 122 from the first position (as shown in FIG. 8) toward the second position (as shown in FIG. 10). When the handle 122 rotates from the first position toward the second position, the first slot 12420 of the support member 1242 drives the driving portion 12440 to drive the rotating member 1244 to rotate, such that the driving portion 12440 moves away from the first slot 12420 and enters the second slot 12422, as shown in FIG. 10. In this embodiment, the rotating member 1244 may comprise a pushing portion 12442. Ehen the handle 122 rotates from the first position toward the second position, the stop portion 12404 of the driving member 1240 moves away from the stop member 104 and the pushing portion 12442 of the rotating member 1244 drives the stop member 104 to drive the tray body 120 to move toward the inside of the casing 10, such that the third electrical connector 130 of the tray 12 is connected to the first electrical connector 100 of the casing 10.

[0032] As shown in FIGS. 5 to 7, the tray body 120 may comprise a guiding groove 1202, the second transmission mechanism 126 may comprise a linking groove 1260, and the first transmission mechanism 124 may further comprise a linking member 1250. The linking member 1250 is disposed on the driving member 1240 and passes through the guiding groove 1202 and the linking groove 1260. The guiding groove 1202 may be arc-shaped and the linking groove 1260 may extend along the second direction Y. Thus, when the handle 122 rotates, the linking member 1250 moves along the guiding groove 1202 and drives the linking groove 1260 to drive the second transmission mechanism 126 to move along the first direction X, as shown in FIGS. 9, 11 and 13. In this embodiment, the tray 12 may further comprise a fixing member 136 fixed on the tray body 120. An end of the second transmission mechanism 126 is movably located between the tray body 120 and the fixing member 136. Furthermore, the second transmission mechanism 126 may comprise at least one first positioning groove 1262, and the tray body 120 may comprise at least one first positioning portion 1204. The first positioning groove 1262 extends along the first direction X and the first positioning portion 1204 is disposed in the first positioning groove 1262, so as to position the second transmission mechanism 126 on the tray body 120. Accordingly, the second transmission mechanism 126 can move along the first direction X. It should be noted that the number and position of the first positioning portions 1204 and the first positioning grooves 1262 may be determined according to practical applications, so the disclosure is not limited to the embodiment shown in the figure.

[0033] As shown in FIG. 7, the second transmission mechanism 126 may comprise a driving gear rack 1264, and the third transmission mechanism 128 may comprise a moving member 1280, a first gear 1282, a socket 1284, a carrier member 1286, a second gear 1288, a cover 1290 and an elastic member 1292. The moving member 1280 comprises a first driven gear rack 12800 and a second driven gear rack 12802. In this embodiment, the moving member 1280 may be U-shaped, and the first driven gear rack 12800 is opposite to the second driven gear rack 12802. The first gear 1282 and the second gear 1288 are disposed between the first driven gear rack 12800 and the second driven gear rack 12802, wherein the first gear 1282 meshes with the first driven gear rack 12800, and the second gear 1288 meshes with the second driven gear rack 12802 and the first gear 1282. Furthermore, the moving member 1280 may comprise at least one second positioning groove 12804 and the tray body 120 may comprise at least one second positioning portion 1206. The second positioning groove 12804 extends along the second direction Y and the second positioning portion 1206 is disposed in the second positioning groove 12804, so as to position the moving member 1280 on the tray body 120. Accordingly, the third transmission mechanism 128 can move along the second direction Y. It should be noted that the number and position of the second positioning portions 1206 and the second positioning grooves 12804 may be determined according to practical applications, so the disclosure is not limited to the embodiment shown in the figure.

[0034] The socket 1284 comprises a rail 12840 and the carrier member 1286 has a sliding portion 12860. An end of the carrier member 1286 is connected to the moving member 1280 and the sliding portion 12860 is disposed in the rail 12840. Accordingly, the moving member 1280 can drive the carrier member 1286 to move with respect to the socket 1284. It should be noted that the number of the sliding portions 12860 and the rails 12840 may be determined according to practical applications, so the disclosure is not limited to the embodiment shown in the figure. The cover 1290 is configured to cover the first driven gear rack 12800, the second driven gear rack 12802, the first gear 1282 and the second gear 1288. In this embodiment, the second transmission mechanism, 126 may comprise two elastic members 1292, wherein opposite ends of one elastic member 1292 are respectively connected to the first driven gear rack 12800 and the cover 1290, and opposite ends of the other elastic member 1292 are respectively connected to the second driven gear rack 12802 and the cover 1292. The elastic member 1292 may be, but is not limited to, a spring.

[0035] As shown in FIG. 9, when the handle 122 is located at the first position, the driving gear rack 1264 is separated from the first gear 1282 by a predetermined distance D. At this time, the driving gear rack 1264 does not mesh with the first gear 1282. As shown in FIG. 11, when the handle 122 rotates from the first position toward the second position, the linking member 1250 of the first transmission mechanism 124 drives the second transmission mechanism 126 to move the predetermined distance D rightward along the first direction X, such that the driving gear rack 1264 meshes with the first gear 1282. Thus, when the handle 122 rotates between the first position and the second position, the driving gear rack 1264 does not mesh with the first gear 1282, such that the third transmission mechanism 128 remains stationary.

[0036] As mentioned in the above, when the handle 122 rotates from the first position toward the second position, the pushing portion 12442 of the rotating member 1244 drives the stop member 104 to drive the tray body 120 to move toward the inside of the casing 10, such that the third electrical connector 130 of the tray 12 is connected to the first electrical connector 100 of the casing 10. Then, the user may continue to rotate the handle 122 from the second position (as shown in FIGS. 10 and 11) toward the third position (as shown in FIGS. 12 and 13). When the handle 122 rotates from the second position toward the third position, the first transmission mechanism 124 drives the second transmission mechanism 126 to move rightward along the first direction X. At this time, the driving gear rack 1264 drives the first gear 1282 to rotate, and the first gear 1282 drives the second gear 1288 to rotate. At the same time, the first gear 1282 drives the first driven gear rack 12800 to move upward along the second direction Y, and the second gear 1288 also drives the second driven gear rack 12802 to move upward along the second direction Y, such that the moving member 1280 drives the carrier member 1286 to move upward along the second direction Y. Accordingly, the carrier member 1286 drives the fourth electrical connector 132 of the tray 12 to move upward along the second direction Y, such that the fourth electrical connector 132 of the tray 12 is connected to the second electrical connector 102 of the casing 10. Consequently, the assembly of the tray 12 and the casing 10 is completed.

[0037] As shown in FIGS. 10 and 12, when the handle 122 rotates between the second position and the third position, the driving portion 12440 of the rotating member 1244 is located in the second slot 12422 of the support member 1242 without restriction (i.e. the driving portion 12440 can move freely in the second slot 12422), such that the rotating member 1244 remains stationary.

[0038] When the user wants to disassemble the tray 12 from the casing 10, the user may first rotate the handle 122 from the third position (as shown in FIGS. 12 and 13) toward the second position (as shown in FIGS. 10 and 11). When the handle 122 rotates from the third position toward the second position, the first transmission mechanism 124 drives the second transmission mechanism 126 to move leftward along the first direction X. At this time, the driving gear rack 1264 drives the first gear 1282 to rotate, and the first gear 1282 drives the second gear 1288 to rotate. At the same time, the first gear 1282 drives the first driven gear rack 12800 to move downward along the second direction Y, and the second gear 1288 also drives the second driven gear rack 12802 to move downward along the second direction Y, such that the moving member 1280 drives the carrier member 1286 to move downward along the second direction Y. Accordingly, the carrier member 1286 drives the fourth electrical connector 132 of the tray 12 to move downward along the second direction Y, such that the fourth electrical connector 132 of the tray 12 is separated from the second electrical connector 102 of the casing 10. When the handle 122 is located at the second position, the driving gear rack 1264 begins to disengage from the first gear 1282. The disclosure may use the elastic member 1292 to keep the moving member 1280 at the best position where the driving gear rack 1264 can mesh with the first gear 1282.

[0039] Then, the user may continue to rotate the handle 122 from the second position (as shown in FIGS. 10 and 11) toward the first position (as shown in FIGS. 8 and 9). When the handle 122 rotates from the second position toward the first position, the support member 1242 drives the driving portion 12440 to drive the rotating member 1244 to rotate, such that the driving portion 12440 moves away from the second slot 12422 and enters the first slot 12420, as shown in FIG. 8. Furthermore, when the handle 122 rotates from the second position toward the first position, the pushing portion 12442 of the rotating member 1244 moves away from the stop member 104 and the stop portion 12404 of the driving member 1240 drives the stop member 104 to drive the tray body 120 to move toward the outside of the casing 10, such that the third electrical connector 130 of the tray 12 is separated from the first electrical connector 100 of the casing 10. Accordingly, the user can disassemble the tray 12 from the casing 10.

[0040] Referring to FIGS. 14 to 16, FIG. 14 is an inside view illustrating the handle 122 located at the first position according to another embodiment of the disclosure, FIG. 15 is an inside view illustrating the handle 122 located at the second position according to another embodiment of the disclosure, and FIG. 16 is an inside view illustrating the handle 122 located at the third position according to another embodiment of the disclosure.

[0041] As shown in FIGS. 14 to 16, the disclosure may replace the aforesaid moving member 1280 by a moving member 1280, and the second transmission mechanism 126 comprises a driving rod 1266. In this embodiment, the disclosure may omit the driving gear rack 1264, the first gear 1282, the second gear 1288, the first driven gear rack 12800 and the second driven gear rack 12802 mentioned in the above. In this embodiment, the moving member 1280 may comprise a straight slot 12806, an inclined slot 12808 and a retaining recess 12810, wherein the straight slot 12806 is connected to the inclined slot 12808, and the inclined slot 12808 is connected to the retaining recess 12810. The straight slot 12806 extends along the first direction X, and the inclined slot 12808 is inclined downward with respect to the first direction X. It should be noted that the same elements in FIGS. 14-16 and FIGS. 8-13 are represented by the same numerals, so the repeated explanation will not be depicted herein again.

[0042] As shown in FIG. 14, when the handle 122 is located at the first position, the driving rod 1266 is located at a side of the straight slot 12806 and separated from the inclined slot 12808 by a predetermined distance D. As shown in FIG. 15, when the handle 122 rotates from the first position toward the second position, the linking member 1250 of the first transmission mechanism 124 drives the second transmission mechanism 126 to move the predetermined distance D rightward along the first direction X, such that the driving rod 1266 moves to the inclined slot 12808. Thus, when the handle 122 rotates between the first position and the second position, the driving rod 1266 is located in the straight slot 12806 without restriction, such that the third transmission mechanism 128 remains stationary. As shown in FIG. 16, when the handle 122 rotates from the second position toward the third position, the linking member 1250 of the first transmission mechanism 124 drives the second transmission mechanism 126 to move rightward along the first direction X, and the driving rod 1266 pushes the inclined slot 12808 rightward, such that the moving member 1280 drives the carrier member 1286 to move upward along the second direction Y. When the handle 122 is located at the third position, the driving rod 1266 is retained in the retaining recess 12810.

[0043] On the contrary, when the handle 122 rotates from the third position toward the second position, the linking member 1250 of the first transmission mechanism 124 drives the second transmission mechanism 126 to move leftward along the first direction X, and the driving rod 1266 is separated from the retaining recess 12810 to push the inclined slot 12808 leftward, such that the moving member 1280 drives the carrier member 1286 to move downward along the second direction Y. When the handle 122 rotates from the second position toward the first position, the linking member 1250 of the first transmission mechanism 124 drives the second transmission mechanism 126 to move the predetermined distance D leftward along the first direction X, such that the driving rod 1266 moves to the position shown in FIG. 14.

[0044] As mentioned in the above, the disclosure may dispose the first electrical connector and the second electrical connector on the casing, dispose the third electrical connector on the tray body of the tray, and dispose the fourth electrical connector on the third transmission mechanism of the tray, wherein the third electrical connector corresponds to the first electrical connector and the fourth electrical connector corresponds to the second electrical connector. When a user puts the tray into the casing, the user may rotate the handle from the first position toward the second position. At this time, the first transmission mechanism drives the second transmission mechanism to move along the first direction, such that the third electrical connector is connected to the first electrical connector. Then, the user may rotate the handle from the second position toward the third position. At this time, the first transmission mechanism drives the second transmission mechanism to move along the first direction and the second transmission mechanism drives the third transmission mechanism to move along the second direction, such that the fourth electrical connector is connected to the second electrical connector. On the other hand, when the user wants to disassemble the tray from the casing, the user may first rotate the handle from the third position toward the second position to separate the fourth electrical connector from the second electrical connector, and then rotate the handle from the second position toward the first position to separate the third electrical connector from the first electrical connector. Accordingly, the user can conveniently and rapidly assemble and disassemble the tray.

[0045] Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
