[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] This utility model embodiment provides a hard disk bay, such as Figure 1 As shown, it includes:

[0044] In some embodiments, the housing 100 is a cylindrical structure with a rectangular cross-section and closed at one end;

[0045] The hard drive pull-out enclosure 200 is a slot-shaped structure with one end open, and the hard drive pull-out enclosure 200 is slidably engaged with the housing;

[0046] A front cover plate 300 is rotatably connected to the first side wall of the hard disk pull-out box 200. A locking hook structure 310 is provided at the end of the front cover plate 300 away from the first side wall. In some embodiments, the first edge of the front cover plate 300 is rotatably connected to one of the side wall edges at the opening end of the hard disk pull-out box 200, and a locking hook structure 310 is provided at the second edge of the front cover plate 300 opposite to the first edge.

[0047] A locking mechanism includes a locking spring 410 and a top block 420. The locking spring 410 is disposed on the second side wall of the hard disk pull-out enclosure 200, which is opposite to the first side wall. The locking spring 410 is used to engage with the locking hook structure 310 to fix the front cover 300 to the second side wall. The top block 420 is disposed on the housing 100 and slides against the locking spring 410. In some embodiments, the locking mechanism includes a locking spring 410 disposed in the hard disk pull-out enclosure 200 at a position corresponding to the second edge and a top block 420 disposed in the housing 100 at a position corresponding to the locking spring 410. The top block 420 is used to press the locking spring 410 when it comes into contact with the locking spring 410, causing the locking hook structure 310 to disengage from the locking spring 410.

[0048] The self-locking mechanism includes a self-locking module 510 and a locking pin 520. The self-locking module 510 is disposed on the second side wall, and one end of the locking pin 520 is disposed on the housing 100, while the other end of the locking pin is slidably disposed within the self-locking module 510. The locking pin 520 is used to restrict the hard disk pull-out enclosure 200 from moving relative to the housing 100 in a cyclical manner according to a first distance, a second distance, a third distance, and so on.

[0049] In the technical solution provided by this utility model embodiment, the relative movement distance between the hard drive pull-out enclosure and the housing is controlled by a self-locking mechanism. Furthermore, the locking spring in the locking mechanism presses against and separates from the top block through this relative movement distance, thereby enabling the front cover to be opened by applying force. The technical solution provided by this utility model embodiment allows for the removal and replacement of the hard drive without any disassembly tools.

[0050] As an optional implementation method, such as Figure 2-6 As shown, the self-locking module 510 includes four sliding grooves connected end to end, wherein the tail of any one sliding groove protrudes relative to the head of the adjacent sliding groove; one end of the locking pin 520 is slidably engaged with the four sliding grooves.

[0051] In some embodiments, when the locking pin 520 slides along the four connected slide grooves, the hard disk pull-out box 200 moves in a cyclic manner relative to the housing 100 according to a first distance, a second distance, a first distance, and a third distance. When the hard disk pull-out box 200 moves a second distance relative to the housing 100, the top block 420 disengages from the locking spring 410.

[0052] like Figure 2-3As shown, the bottoms of the four grooves (i.e., grooves P1-P2, P2-P3, P3-P4, and P4-P1) are not completely flat. To ensure the locking pin 520 always moves accurately counterclockwise, the bottom height of each groove increases along the direction of the locking pin's movement. Furthermore, the height of the beginning of the next groove is lower than the height of the end of the current groove. This height difference forces the locking pin to move only clockwise. See [link to details] for further information. Figure 3 As shown, at point P2, because the tail of the P1-P2 groove protrudes more than the head of the P2-P3 groove, when the end of the locking pin 520 slides to point P2, the end of the locking pin will fall into the P2-P3 groove. When pressure is applied again, the locking pin cannot return to the P1-P2 groove due to the height difference, and can only slide along the P2-P3 groove. During the sliding process, it is lifted by the ramp in the P2-P3 groove. Similarly, when it reaches point P3, the locking pin 520 will fall into the P3-P4 groove. The principle of the other grooves is the same as that of the P2-P3 groove, and will not be described again here. Throughout the entire movement of the mechanism, the end of the locking pin 520 moves along the counterclockwise trajectory of the closed loop P1->P2->P3->P4->P1. Figure 4 As shown, for example, the distance between the closed end of the hard drive pull-out enclosure 200 and the closed end of the housing 100 can be used as the movement distance of the hard drive pull-out enclosure 200 relative to the housing 100; when the end of the locking pin 520 is at point P1, the movement distance of the hard drive pull-out enclosure 200 relative to the housing 100 is used as the second distance, and the front cover 300 and the locking spring 410 are in a locked state; when the user presses the front panel 300 forcefully, it will force the hard drive pull-out enclosure 200 to move the slide of the self-locking module 510 inward, and when the locking pin 520 reaches point P2, the movement distance of the hard drive pull-out enclosure 200 relative to the housing 100 is used as the first distance, such as... Figure 5 As shown; the hard drive pull-out enclosure 200 cannot slide further inward. At this time, an outward force is applied to the hard drive pull-out enclosure 200. When the end of the locking pin 520 slides to point P3, the movement distance of the hard drive pull-out enclosure 200 relative to the housing 100 is taken as the third distance, such as... Figure 6As shown; at this time, the hard drive pull-out enclosure 200 moves outward from inside the housing 100. During the process from point P2 to P3, the top block 420 will press the locking spring 410 on the hard drive pull-out enclosure 200, causing the spring to deform and disengage from the locking hook structure 310 of the front cover 300. When it reaches point P3, the front cover 300 can be fully opened; that is, the hard drive can be removed and replaced at point P3. When the user closes the front cover 300 and presses and pushes the hard drive pull-out enclosure 200 inward, the self-locking module 510 and the hard drive pull-out enclosure 200 slide inward until they can no longer slide inward. At this time, when the end of the locking pin 520 moves from point P3 to P4, the movement distance of the hard drive pull-out enclosure 200 relative to the housing 100 is taken as the first distance, such as... Figure 7 As shown; at this time, an outward force is applied to the hard drive pull-out enclosure 200, the end of the locking pin 520 moves from point P4 to P1, the movement distance of the hard drive pull-out enclosure 200 relative to the housing 100 returns to the second distance, the locking hook structure 310 of the front cover 300 is locked by the locking spring 410, and the entire mechanism is in a locked state, as shown. Figure 4 As shown. The outward force applied to the hard drive pull-out enclosure 200 can originate from, for example, an elastic mechanism.

[0053] As an optional implementation method, such as Figure 1 and Figure 8 As shown, the locking pin 520 includes an extension 523 and a first bent portion 521 and a second bent portion 522 respectively disposed at both ends of the extension 520. The first bent portion 521 is slidably engaged with the four sliding grooves.

[0054] The self-locking mechanism also includes:

[0055] A locking pin fixing seat 540 is disposed on the housing 100, and the second bent portion 522 is connected to the locking pin fixing seat 540;

[0056] A clamping spring 530 is disposed on the locking pin fixing seat 540. The clamping spring 530 is used to provide elastic force to the extension 523, so that the first bending part 521 is pressed against the bottom of the four slide grooves.

[0057] In some embodiments, the locking pin fixing seat 540 is disposed on the lower base plate 101 of the housing 100, and the locking pin 520 is pressed by the clamping spring 530, so that the second bent portion 522 of the locking pin 520 always contacts the bottom of the slide groove, forcing the locking pin 520 to always move in a single clockwise or counterclockwise direction within a closed-loop motion trajectory. Of course, other types of locking pins 520 and other compression methods can also be used, for example, using a locking pin 520 that is perpendicular to the upper cover plate and slidably connected to the upper cover plate, and using a spring to press the locking pin 520 downward.

[0058] As an optional implementation method, such as Figure 9-10 As shown, the hard drive pull-out enclosure 200 includes a bottom wall 201 disposed at the bottom, and the housing 100 includes a lower bottom plate 101;

[0059] The bottom wall 201 of the hard drive pull-out enclosure 200 is provided with a first sliding mechanism 110, and the upper surface of the bottom plate 101 of the housing 100 is provided with a second sliding mechanism 210. The first sliding mechanism 110 and the second sliding mechanism 210 cooperate with each other.

[0060] In some embodiments, the first sliding mechanism 110 may be a raised elongated slider, and the second sliding mechanism 210 may be a recessed elongated groove. Through the cooperation of the slider and the groove, it can be ensured that the hard disk pull-out box 200 and the housing 100 move only in a straight line, and at the same time, the movement can be limited.

[0061] As an optional implementation method, such as Figure 11-12 As shown, the housing 100 also includes an upper cover plate 102 disposed on the top;

[0062] The upper cover plate 102 of the housing 100 is provided with a first stacking mounting hole 120, and the lower cover plate of the housing 100 is provided with a second stacking mounting hole 130 at a position corresponding to the first stacking mounting hole 120.

[0063] In some embodiments, during user operation, it is inevitable that multiple hard drives will need to be used together. Therefore, this embodiment provides a method to stack multiple hard drive bays. The bottom plate 101 of the upper hard drive bay is connected to the top cover plate 102 of the lower hard drive bay, and then the upper hard drive bay is assembled to obtain a stacked hard drive bay.

[0064] As an optional implementation method, such as Figure 13 As shown, the first end of the locking spring 410 is provided with a hook structure 411, which can engage with the locking hook structure 310. The middle part of the locking spring 410 facing the top block 420 is provided with a deformable part 412. The deformable part 412 is used to disengage the hook structure 411 from the locking hook structure 310 when it is pressed by the top block 420. The deformable part 412 is also used to securely connect the hook structure 411 to the locking hook structure 310 when it is not pressed by the top block 420.

[0065] In some embodiments, the locking hook structure 310 of the front cover 300 and the latching hook structure 411 of the locking spring 410 hook each other to form an interlocked state, which firmly fixes the hard drive in the hard drive compartment. The hard drive compartment will only be disengaged and unlocked when it is ejected.

[0066] As an optional implementation, continue as follows Figure 13 As shown,

[0067] The locking mechanism further includes:

[0068] A spring clip bracket is disposed on the second side wall 202. The spring clip bracket includes fixing brackets 413 and 414 and mounting bracket 415. One end of the locking spring clip 410 away from the hook structure 411 is fixed to the mounting bracket 415. The mounting bracket 415 presses the two sides of the locking spring clip 410 along the length direction onto the second side wall 202.

[0069] As an optional implementation method, such as Figure 1 as well as Figure 4-7 As shown, the hard drive bay also includes a pre-tightening elastic mechanism 600. One end of the pre-tightening elastic mechanism 600 is connected to the housing 100, and the other end of the pre-tightening elastic mechanism 600 is connected to the hard drive pull-out box 200. The pre-tightening elastic mechanism 600 is used to provide a pre-tightening force for the hard drive pull-out box 200 to move away from the housing 100.

[0070] In some embodiments, the pre-tensioning elastic mechanism 600 may be, for example, a spring, which always maintains a force that pushes the hard drive pull-out enclosure 200 outward.

[0071] As an optional implementation method, such as Figure 14 As shown, the hard drive pull-out enclosure 200 includes a back wall 203 away from the opening end, and the housing 100 includes a back plate 103 away from the opening end.

[0072] The hard drive pull-out enclosure 200 has a hard drive socket 700 on its back wall 203; the back plate 103 of the housing 100 has a notch so that the hard drive socket 700 can extend out through the notch.
