As shown in FIG. 1, a chassis 1000 of a first embodiment includes a first frame 200 and a second frame 300. A plurality of first modules 400 is mounted in the first frame 200. A plurality of second modules 500 is mounted in the second frame 300. As the first frame 200 moves in the second frame 300 along a first direction X, the first modules 400 are moved to be close to or be away from the second modules 500. The first module 400 could a data storage module. The second module 500 could be an HDD (Hard Disk Drive) module. The first module 400 has a first connector 410. The second module 500 has a second connector 510. When the first connector 410 is plugged into the second connector 510, the first module 400 and the second module 500 are electrically connected to pass electrical signals between the first module 400 and the second module 500.

The chassis 1000 further includes two locking assemblies 100 and two limiting components 50. The two locking assemblies 100 are mounted on both sides of the first frame 200. The two locking assemblies 100 are spaced in the second direction Y. The second direction Y is perpendicular to the first direction X. The two limiting components are mounted on the second frame 300. One of the two limiting components 50 is mounted on one side in the second direction Y of the second frame 300. The other of the two limiting components 50 is mounted on the other side in the second direction Y of the second frame 300. Each of the locking assemblies 100 couples to one of the limiting components 50 to lock the first frame 200 and the second frame 300 in the first direction X.

As shown in FIGS. 1 and 2, each of the two locking assemblies 100 includes a shell 10, a sliding component 20, a transmission group 30 (shown in FIG. 5) and a locking block 33. Each of the two limiting components 50 includes a locking member 50a (shown in FIG. 7). The limiting components 50 is coupled to the second frame 300. The locking block 33 is protruded from a top side 13 of the shell 10 to fit the locking member 50a. The top side 13 is one of the sides of the shell 10 in a third direction Z. The third direction Z perpendicular to the first direction X and the second direction Y. When the sliding component 20 is moved relatively to the shell 10 in the first direction X, the locking block 33 can be driven by the transmission group 30 to act on the locking member 50a. The locking block 33 can be blocked by the locking member 50a and the first frame 200 can be restricted to move away from the second frame 300 in the first direction X. When the first connector 410 of the first module 400 is plugged into the second connector 510 of the second module 500, the locking block 33 is acted on the locking member 50a for preventing the first connector 410 from detaching from the second connector 510 in the first direction X.

As shown in FIGS. 2, 3 and 4, the sliding component 20 has two sliding slots 22. Each of the two sliding slots 22 extends along the first direction X. The shell 10 has two sliding columns 1b. Each of the two sliding columns 1b is inserted into one of the two sliding slots 22. The sliding component 20 can be guided in the first direction X relatively to the shell 10 by sliding the sliding column 1b in the sliding slot 22. Two sliding columns lb are inserted into two sliding slots 22 to limit the tilt of the sliding component 20 as the sliding component 20 slides against the shell 10. In some embodiments, the diameter of the sliding columns 1b is substantially equal to the slot width of the sliding slots 22 to prevent the sliding component 20 from wobbling on the guide member 1b along the third direction Z.

The sliding component 20 further has a guiding slot 21. The transmission group 30 includes a guiding column 32. The guiding column 32 is inserted into the guiding slot 21 and can be slid in the direction of the extension of the guiding slot 21. The guiding slot 21 has a first segment 2a and a second segment 2b. The first segment 2a and the second segment 2b are continuous. The first segment 2a roughly parallel to the first direction X. The second segment 2b is at an obtuse angle to the first segment 2a. As the sliding component 20 slides into the shell 10 along the first direction X, the guide column 32 is slid towards the top side 13 of the shell 10 under the guidance of the second segment 2b.

The shell 10 includes a first board 11 and a second board 12. The first board 11 is detachably connected to the second board 12. A cavity 122 is defined between the first board 11 and the second board 12 for holding the sliding component 20. The transmission group 30 is mounted between the first board 11 and the second board 12. The two sliding slots 22 and the guiding slot 21 are located on the second board 12. The sliding component can be inserted between the first board 11 and the second board 12 by the guiding of the sliding slots 22 to drive the transmission group 30. The second board 12 includes a plate 121, a first flap 123 and a second flap 125. The first flap 123 and the second flap 125 are coupled to each side of the plate 121. The first flap 123 extends in the direction towards the second flap 125. The second flap 125 extends in the direction towards the first flap 123. One side of the sliding component 20 is held by the first flap 123 and the plate 121, the other side of the sliding component 20 is held by the second flap 125 and the plate 121. The first flap 123 and the second flap 125 are located between the plate 121 and the first board 11. The sliding component 20 is restricted by the first flap 123 and the second flap 125 from approaching the first board 11 along the second direction Y.

Two first mounting holes 1231 are defined on the first flap 123. Two second mounting holes 111 are defined on the first board 11. Three third mounting holes 1251 are defined on the second flap 125. Three fourth mounting holes 113 are defined on the first board 11. The shell 10 further includes five fasteners 14. Each of the five fasteners 14 could be a rivet or a screw. Two of the fasteners 14 pass through the first mounting hole 1231 and the second mounting hole 111 to secure the first board 11 and the second board 12. Three of the fasteners 14 pass through the third mounting hole 1251 and the fourth mounting hole 113 to secure the first board 11 and the second board 12.

The second board 12 further includes a third flap 127. The third flap 127 is located at one end of the plate 121 along the first direction X. The third flap 127 is configured to prevent the sliding component 20 from passing through the shell 10 and acting on the first modules 400. Two fifth mounting holes 1271 are defined on the third flap 127 for detachably mounting the shell 10 on the first frame 200.

As shown in FIGS. 5 and 6, the transmission group 30 further includes a first block 31 and a second block 34. The first block 31 is rotatably connected to the first board 11 around a first axis 3a. The guiding column 32 passes through a first hole in the first block 31 and a second hole in the second block 34, so that the guiding column 32 is rotatably connected to both the first block 31 and the second block 34. The second block 34 is rotatably connected to the locking block 33 around a second axis 3b. The locking block 33 is rotatably connected to the first board 11 around a third axis 3c. The first axis 3a, the second axis 3b and the third axis 3c are parallel to the second direction Y. The locking block 33 includes a first clamping part 331 and a second clamping part 333. A clamping notch 335 is formed between the first clamping part 331 and the second clamping part 333.

Once the locking member 50a is in the clamping notch 335 and the guiding column 32 is in the first segment 2a, and the first axis 3a, the second axis 3b and the guide column 32 are configured in approximately a same straight line, which is parallel to the first direction X. The first axis 3a is located between the second axis 3b and the guide projection. If the locking block 33 tends to move along the first direction X relative to the locking member 50a, the locking member 50a generates a thrust that tends to push the locking block 33 rotate around the third axis 3c. The locking block 33 tends to push the second block 34 along the first direction X. The second segment 2b is at the obtuse angle to the first segment 2a. However, the first axis 3a, the second axis 3b and the guiding column 32 are configured in the straight line parallel to the first direction X that it is difficult to generate a third direction Zal force to bring the guiding column 32 into the second segment 2b. The relative positions of the locking block 33 and locking member 50a in the first direction X are locked. Thus, the relative positions of the first frame 200 and the second frame 300 in the first direction X are locked.

The guiding slot 21 further has a third segment 2c. The third segment 2c is at the end of the second segment 2b away from the first segment 2a. The third segment 2c is a curved slot with the axis of the curved slot located on the side of the curved slot away from the top side 13. The guiding column 32 can enter the third segment 2c from the second segment 2b when the sliding component 20 is pulled out from the shell 10 along the first direction X. The transmission group 30 further includes an elastic member 36. The elastic member 36 could be a spring. One end of the elastic member 36 is connected to the first board 11, the other end of the elastic member 36 is connected to the second block 34.

The second block 34 has a first part 341 and a second part 343. The second part is fixedly connected to the first part. The second part extends perpendicular to the first part from the middle area of the first part. One end of the first part is rotatably connected to the guiding column 32. The other end of the first part is rotatably connected to the locking block 33 around the third axis 3c. The first board 11 includes a first connecting column 37. The second part 343 includes a second connecting column 38. One end of the elastic member 36 is connected to the first connecting column 37. The other end of the elastic member 36 is connected to the second connecting column 38.

The elastic member 36 makes the second block 34 tend to drive the guiding column 32 towards the first segment 2a. When the sliding component 20 moves in the first direction X relative to the shell 10 so that the guiding column 32 slides into the end of the third segment 2c away from the second segment 2b. The line of the guiding column 32 to the second axis 3b is parallel to the third direction Z. The elastic member 36 drives the guiding column 32 close to the second segment 2b along the third segment 2c, so that the first block 31 rotates around the first axis 3a. Meanwhile, the second block 34 moves towards the first segment 2a, so that the locking block 33 rotates around the second axis 3b to unlock the locking member 50a.

The shell 10 further includes a stopper 35. The stopper 35 is mounted on the first board 11 and extends towards the second board 12. When the elastic member 36 drives the guiding column 32 close to the second segment 2b along the third segment 2c, the first block 31 can be blocked by the stopper 35 to prevent the first block 31 from rotating around the first axis 3a. So that, the guiding column 32 stops at the end of the third segment 2c near the second segment 2b, which prevents the sliding component 20 from moving away from the shell 10 along the first direction X.

The second block 34 is located on the side of the first block 31 away from the first board 11. The dimension of the stopper 35 along the second direction Y is smaller than the dimension of the first block 31 along the second direction Y, so that the stopper 35 cannot extend into the area where the second block 34 is located to prevent the stopper 35 from affecting the movement of the second block 34.

Referring to FIG. 4, the sliding component 20 further has a limiting notch 23, which is located at the side of the sliding component 20 away from the first segment 2a. The shell 10 further includes a limiting column 1a. The limiting notch 23 is configured to accommodate the limiting column 1a, and the movement of the sliding component 20 can be restricted by the cooperation of the limiting notch 23 and the limiting column 1a.

The limiting notch 23 has an opening 231 for the limiting column 1a to enter the limiting notch 23 through the opening 231. The limiting column 1a and the limiting notch 23 may limit the movement of the sliding component 20 by interference fitting. In some embodiments, the opening 231 of the limiting notch 23 is provided with a closing, so that the size of the opening 231 is smaller than the diameter of the limiting column 1a before deformed by force. The limiting column 1a is made of elastic material. When the sliding component 20 moves along the first direction X to drive the limiting notch 23 towards the limiting column 1a, the closing of the limiting notch 23 can squeeze the limiting column 1a. The limiting column 1a is elastically deformed by the closing to enter the limiting notch 23 through the opening 231. After the limiting column 1a enters the limiting notch 23, the closing of the limiting notch 23 can the sliding component 20 in a locked state. Meanwhile, if the external force on sliding component 20 is not sufficient to deform the limiting column 1a to pass through the opening 231, the position of the sliding component 20 with the shell 10 in the first direction X remains stable.

As shown in FIG. 7, when the first frame 200 is locked in the second frame 300, the locking assembly 100 is located with the second frame 300, and the first clamping part 331 acts on the locking member 50a of the second frame 300. The locking member trends to generate a torque on the locking block 33 to rotate the locking block 33 around the third axis 3c. At the same time, the second block 34 trends to rotate through the locking block 33, and drive the guiding column 32 from the first segment 2a to the second segment 2b. However, since the line connecting the first axis 3a, the second axis 3b and the guide pillar 32 is approximately parallel to the first direction X, the torque generated by the locking member 50a is difficult to drive the guiding column 32 from the first segment 2a to the second segment 2b.

As shown in FIG. 10, in the process of pulling the first frame 200 from the second frame 300 along the first direction X, when the guide column 32 moves to the end of the third segment 2c, the sliding component 20 cannot be pulled along the first direction X relative the shell 10 further. However, as the elastic member 36 pulls the second block 34, which causes the second block 34 to drive the first block 31 to rotate around the first axis 3a, the guiding column 32 slides from the third segment 2c toward the second segment 2b.

FIGS. 7 to 11 show the transition of the locking assembly 100 from a locked state to an unlocked state during the process of pulling the first frame 200 out of the second frame 300.

As shown in FIGS. 7 to 10, a first extraction stage is: the first frame 200 is pulled out from the second frame 300 by pulling the sliding component 20, so that the sliding component 20 moves forward relative to the shell 10 and the guiding column 32 moves from the first segment 2a to the second segment 2b. Since the extension direction of the second segment 2b is inclined to the first direction X, the guiding column 32 has a displacement in the third direction Z when sliding along the second segment 2b. The first block 31 rotates around the first axis 3a driven by the guiding column 32. The second block 34 rotates driven by the guiding column 32, and the locking block 33 rotates driven by the second block 34, so that the first clamping part 331 is gradually removed from the locking member 50a. Continuously pulling out the sliding component 20 from the shell 10, so that the guiding column 32 moves from the second segment 2b to the third segment 2c. The third segment 2c is a curved slot with the axis of the curved slot located on the side of the curved slot away from the top side 13. When the guiding column 32 moves to the end of the third segment 2c, the line of the guiding column 32 to the second axis 3b is parallel to the third direction Z.

As shown in FIGS. 10 to 12, the second extraction stage is: The elastic member 36 drives the guiding column 32 close to the second segment 2b along the third segment 2c, so that the first block 31 rotates around the first axis 3a. The first block 31 rotates the locking block 33 around the second axis 3b through the second block 34, and the locking block 33 drives the clamping notch 335 around the locking member 50a to unlock the locking member 50a and the clamping notch 335. Since the locking member 50a is out of the clamping notch 335, the first frame 200 can be moved away from the second frame 300 along the first direction X by continuously pulling the sliding component 20 in the first direction X.

FIGS. 12 to 15 show the transition of the locking assembly 100 from a unlocked state to a locked state during the process of pushing the first frame 200 into the second frame 300.

As shown in FIGS. 12 and 13, a first push-in stage is: the first frame 200 is pushed into the second frame 300 along the first direction X. Meanwhile, the sliding component 20 is stationary relative to the shell 10, the second clamping part 333 is not in contact with the locking member 50a, and the guiding column 32 is in the third segment 2c.

As shown in FIGS. 13 and 14, a second push-in stage is: when the second clamping part 333 contacts the locking member 50a, continue to push the sliding component 20, the locking block 33 rotates under the block of the locking member 50a so that the locking member 50a gets into the clamping notch 335. When the locking block 33 rotates, the locking block 33 drives the first block 31 to rotate through the second block 34, and the guiding column 32 moves toward the end of the third segment 2c.

As shown in FIGS. 14 and 15, the third push-in stage is: when the guiding column 32 moves to the end of the third segment 2c, continue to push the sliding component 20, and the guiding column 32 moves into the second section 2b. Since the extension direction of the second segment 2b is inclined to the first direction X, the moving of the column rotates the first block 31 around the first axis 3a, and moves the guiding column 32 to the side of the first axis 3a away from the second axis 3b.

As shown in FIGS. 7 and 15, the fourth push-in stage is: when the guiding column 32 moves to the first segment 2a, the first clamping part 331 acts on the locking member 50a. The first frame 200 can be pushed into the second frame 300 by pushing the sliding component 20 along the first direction X. As the first frame 200 is pushed into the second frame 300, the first connector 410 of the first module 400 can be plugged into the second connector 510 of the second module 500.

The locking assembly 100 further includes a handle 40. The handle 40 is connected to the sliding component 20. Users can hold the handle 40 and pull the handle 40 along the first direction X for driving the sliding component 20 along the first direction X.

The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including, the full extent established by the broad general meaning of the terms used in the claims.
