[0047] The present application provides a hard disk fixing mechanism 100, as shown in Figures 1-3 comprising:

[0048] a base 1 in which a receiving cavity 10 is formed, a first locking hook 11 is formed at the bottom of the receiving cavity 10, the base 1 can be in a hollow structure, a first locking hook 11 outer wall 11A extends in the vertical direction at the bottom of the base 1, a hook body 11B extends in the horizontal direction at the bottom end of the outer wall 11A, and the hook body 11B is used to clamp the substrate on which the hard disk is arranged;

[0049] The upper cover 2 is slidably connected with the base 1, and by sliding the upper cover 2, a fixing area 20 for fixing a hard disk is opened or covered. The upper cover 2 has a clamping groove 21 extending in a horizontal direction on one side thereof. The base 1 can be provided with a protrusion 13 extending in a horizontal direction. The clamping groove 21 and the protrusion 13 can have a certain gap therebetween. A shell for clamping the edge of the hard disk is formed between the clamping groove 21 and the protrusion 13, i.e., the gap between the clamping groove 21 and the protrusion is the fixing area 20. According to different settings, the fixing area 20 can also be formed by the edges of the upper cover 2 and the base 1, i.e., the fixing area 20 can be formed on one side of the hard disk fixing mechanism 100, and no limitation is made in this regard.

[0050] The locking member 3 is rotatably arranged in the accommodating cavity 10. A second locking hook 30 is formed in the extending direction of the first locking hook 11 from the rotating position Q of the locking member 3. An unlocking button 31 is formed at a preset angle with the second locking hook 30 from the rotating position P1 of the locking member 3. The unlocking button 31 protrudes out of the base 1. A through hole can be formed on the side edge of the base 1 away from the fixing area 20. The shape of the through hole can be similar to that of the locking member 3, so that the unlocking button 31 formed on the locking member 3 can protrude out of the through hole. The locking member 3 can rotate about the rotating position Q. The rotation of the locking member 3 can be realized by the cooperation of a rotating shaft and the base 1, or by the cooperation of a circular protrusion formed on both sides of the locking member 3 with a rotating groove on the base 1. The setting is not limited according to actual needs. Specifically, a through hole 12 is formed on the side of the accommodating cavity 10 away from the fixing area 20. The unlocking button 31 protrudes out of the base 1 from the through hole 12. The preset angle can also be nearly 90°, i.e., nearly L-shaped and vertically arranged.

[0051] When the locking member 3 is rotated to the first position P1, the hard disk fixing mechanism 100 is locked on the substrate 201 on which the hard disk is arranged by the cooperation of the first locking hook 11 and the second locking hook 30. When the locking member 3 is rotated to the second position P2, the second locking hook 30 is close to the first locking hook 11, and the hard disk fixing mechanism 100 is unlocked from the substrate 201.

[0052] In Figure 2In the (A), the hard disk fixing mechanism 100 is clamped to the base plate 201 of the hard disk module 200. First, the fixed first locking hook 11 is clamped to the locking hole 202 on the base plate 201. Then, the hard disk fixing mechanism 100 is pressed to the base plate 201, so that the edge of the second locking hook 30 is against the edge of the locking hole 202 and is turned to the side of the first locking hook 11, and the second locking hook 30 is clamped to the locking hole 202. After the second locking hook 30 is clamped to the locking hole 202, the second locking hook 30 is turned to the side away from the first locking hook 11 under the action of an external force, and is clamped to the bottom surface of the base plate 201, so that the hard disk fixing mechanism 100 is locked, as shown in Figure 2 (B). At this time, the hard disk fixing mechanism 100 can fix the clamped hard disk in the fixing area 20, as shown in 3(A) in Figure 3 .

[0053] When the hard disk fixing mechanism 100 needs to be removed, the clamped hard disk 203 is released by operating the upper cover 2. Under the action of the connector 204, the released hard disk 203 can be popped up via the action of the connector 204, as shown in Figure 3 (B). It should be noted that the connector 204 can also not have the pop-up function, so that the released hard disk 203 can be manually taken out by the staff. Thereafter, if the hard disk fixing mechanism 100 needs to be removed, the staff can lift the unlocking button 31 of the locking member 3, and the locking member 3 is turned around the turning position Q, as shown in Figure 2 (C). The second locking hook 30 is close to the first locking hook 11, and the distance between the second locking hook 30 and the first locking hook 11 is less than the locking hole 202, so that the hard disk fixing mechanism 100 can be removed from the hard disk module 200, so as to quickly realize the maintenance of the hard disk module 200.

[0054] In the embodiment of the present application, in the above hard disk fixing mechanism, the hard disk is fixed by the cooperation of the slidable upper cover and the base, and the locking and unlocking between the hard disk fixing mechanism and the base plate provided with the hard disk are realized by the second locking hook on the rotatable locking member and the first locking hook provided on the base, so that the installation and removal of the hard disk module can be quickly completed during the maintenance of the electronic equipment, and the maintenance efficiency of the electronic equipment is improved.

[0055] Optionally, the base 1, as shown in Figure 4 , further comprises:

[0056] The positioning column 14 is arranged at the bottom of the base 1 and is located at the outer circumferential side of the first locking hook 11 and the second locking hook 30. The positioning column 14 cooperates with the positioning hole 205 on the base plate 201 provided with the hard disk.

[0057] Since the first and second locking hooks 11 and 30 need to be inserted into the locking hole 202 for fixation, in the case that the locking hole 202 is circular, the hard disk fixation mechanism 100 fixed to the base plate 201 can have a rolling problem due to vibration, thus causing the hard disk 203 to be detached. In order to avoid the above-mentioned situation, a positioning column 14 can be arranged at the outer circumferential side of the first and second locking hooks 11 and 30, and the bottom end of the positioning column 14 can be formed in a circular arc structure so as to have a certain guiding effect. When the hard disk fixation mechanism 100 is inserted into the base plate 201, the positioning column 14 is clamped into the positioning hole 205 of the base plate 201, so that the hard disk fixation mechanism 100 can be fixed to the base plate 201 in a multi-point manner, thus avoiding the influence of vibration.

[0058] Further, as shown in Figure 4 , the number of the positioning columns 14 is two, which are arranged at the bottom of the two sides of the base 1.

[0059] By increasing the number of the positioning columns 14, two positioning holes 205 are correspondingly formed on the base plate 201 to realize cooperation, so that the hard disk fixation mechanism 100 can form a more stable structure in the hard disk module 200, thus further improving the fixation reliability of the hard disk fixation mechanism 100 to the hard disk.

[0060] Optionally, the locking member 3, as shown in Figure 5 , further comprises:

[0061] a first hook 32 arranged between the rotating position Q and the unlocking button 31, and the first hook 32 can be arranged in an arc shape;

[0062] The base 1 further comprises:

[0063] a second hook 15 arranged at the side of the first locking hook 11 and located between the first locking hook 11 and the second locking hook 30 of the locking member 3, and the second hook 15 is formed in a manner that a protrusion is formed on the second hook 15 and a groove is formed on the protrusion, and the side of the first locking hook 11 refers to that the second hook 15 is not directly connected with the first locking hook 11 and has a certain interval therebetween;

[0064] The hard disk fixation mechanism 100 further comprises:

[0065] A first reset spring 40 is hung between the first hook 32 and the second hook 15. The first reset spring 40 can be formed as a tension spring. When the first reset spring 40 is hung on the first hook 32 and the second hook 15, the second hook 15 is fixed in position, and the locking member 3 is subjected to a downward pulling force under the driving of the first reset spring 40, so that the second locking hook 30 of the locking member 3 is maintained at a distance far from the first locking hook 11, clamping the edge of the locking hole 202, and the unlocking button 31 at the other end of the locking member 3 is abutted to the bottom wall of the accommodating cavity 10 of the base 1.

[0066] After the unlocking button 31 is lifted by the staff to unlock the hard disk fixing mechanism 100, the locking member 3 can be restored to the locking state by the pulling force of the first reset spring 40, and the unlocking button 31 of the locking member 3 can be maintained in the locking state without external force and the loosening problem of the hard disk fixing mechanism 100 caused by vibration can be eliminated by the pulling force of the first reset spring 40.

[0067] Of course, the first reset spring 40 can have a certain pulling force structure, and is not limited to a tension spring.

[0068] Optionally, as shown in Figure 6 , a limiting protrusion 33 is formed on the two side surfaces of the side wall of the accommodating cavity 10 towards the unlocking button 31;

[0069] A limiting hole 16 corresponding to the limiting protrusion 33 is arranged on the side wall of the accommodating cavity 10, wherein the width of the limiting hole 16 close to the side of the upper cover 2 is greater than the limiting protrusion 33, and the width of the limiting hole 16 away from the side of the upper cover 2 is less than the limiting protrusion 33.

[0070] The limiting protrusion 33 can be in a cylindrical shape, and the limiting hole 16 can be in various forms, such as two circular holes with different diameters. The larger diameter circular hole (hereinafter referred to as the large circular hole) is at a higher position relative to the smaller diameter circular hole (hereinafter referred to as the small circular hole). The limiting protrusion 33 can be smoothly clamped into the large circular hole, and as the limiting protrusion 33 enters the small circular hole, it abuts against the edge of the small circular hole to limit the movement of the limiting protrusion 33, avoiding excessive rotation of the locking member 3.

[0071] Of course, the limiting hole 16 can also be arranged in other shapes, such as an arc-shaped hole, a strip-shaped hole, etc.

[0072] Optionally, as shown in Figure 6 , 7 , a sliding block 22 is arranged on the two side surfaces of the side wall of the upper cover 2 towards the base 1. The shape of the sliding block 22 can be arranged according to actual needs, such as Figure 7 a strip shape in

[0073] A sliding hole 17 corresponding to the sliding block 22 is formed on the side wall of the base 1, and the sliding of the upper cover 2 relative to the base 1 is realized by the cooperation between the sliding block 22 and the sliding hole 17.

[0074] Optionally, as shown in Figure 6 , 7 , a limiting wall 23 is arranged on the side surface of the upper cover 2 facing the base 1, and a spring accommodating cavity 24 is formed between the limiting wall 23 and the base 1. The limiting wall 23 is arranged on the lower side surface of the upper cover 2, and the limiting wall 23 can be in the shape of an L. The other side of the spring accommodating cavity 24 can be the side wall of the accommodating cavity 10, and the two together form the spring accommodating cavity 24.

[0075] The hard disk fixing mechanism 100 further comprises:

[0076] A second reset spring 41 is arranged in the spring accommodating cavity 24, and the second reset spring 41 is used to push the upper cover 2 to return to the state of shielding the fixing area 20.

[0077] Since the limiting wall 23 is in the shape of an L, the second reset spring 41 cannot fall out of the spring accommodating cavity 24, and when the upper cover 2 is pushed, the second reset spring 41 realizes a pushing force in the opposite direction. When it is necessary to take out or push in the hard disk, as shown in Figure 7 (A), the upper cover 2 reaches the right side, and the second reset spring 41 is compressed. When it is necessary to lock the hard disk, the upper cover 2 is pushed back by the second reset spring 41, as shown in Figure 7 (B), the upper cover 2 reaches the left side, and the upper cover 2 shields the fixing area 20.

[0078] Optionally, as shown in Figure 6 , 7 , a protruding rib 25 is arranged on the side surface of the upper cover 2 away from the base 1.

[0079] Through the protruding rib 25, the worker can more reliably push the upper cover 2 by the arrangement of the protruding rib 25.

[0080] Correspondingly, the application further provides a hard disk module 200, as shown in Figure 2 , comprising:

[0081] A base plate 201, wherein a connector 204 and a locking hole 202 are arranged on the base plate 201;

[0082] A hard disk 203 is inserted into the connector 204; and

[0083] The hard disk fixing mechanism 100 is locked to the base plate 201 through the locking hole 202 by the first locking hook 11 on the base 1 of the hard disk fixing mechanism 100 and the second locking hook 30 on the locking piece 3 of the hard disk fixing mechanism 100.

[0084] The hard disk module 200 can be arranged in an electronic device such as a server, a switch, a router, a firewall or a personal computer, and the like, according to actual needs.

[0085] The base plate 201 of the hard disk module 200 can be a main board of an electronic device, or can be another circuit board fixed to the main board of the electronic device and separated from the main board.

[0086] The hard disk 203 in the hard disk module 200 can be the M.2 hard disk described above, or can be another type of hard disk, and can be adapted to the hard disk fixing mechanism 100 in a plug-in manner.

[0087] The technical scheme provided by the embodiments of the present specification can include the following beneficial effects:

[0088] In the hard disk fixing mechanism described above, the fixing of the hard disk is achieved by the cooperation of the slidable cover and the base, and the locking and unlocking between the hard disk fixing mechanism and the base plate provided with the hard disk is achieved by the second locking hook on the rotatable locking piece and the first locking hook provided on the base, so that during the maintenance of the electronic device, the installation and disassembly of the hard disk module can be quickly completed, and the maintenance efficiency of the electronic device is improved.

[0089] Other embodiments of the present specification will be readily apparent to those skilled in the art upon considering the specification and practicing the invention claimed herein.
