Technical Field

[0001] This invention belongs to the field of hard disk technology, and more specifically, relates to a hard disk structure. Background Technology

[0002] A hard drive is an external storage device for computers that can be used to store computer operating systems, various software, programs, and data.

[0003] In the current technology, hard drives are fixed in the computer case. Most computer cases use screws or clips to secure the hard drive and prevent it from becoming loose. However, due to the limited space in the computer case, screws and clips make it very difficult to remove the hard drive later, which is not conducive to repair. Summary of the Invention

[0004] The main objective of this invention is to provide a hard drive structure that is easy to lock into the chassis and can automatically pop out of the chassis when disassembled.

[0005] According to a first aspect of the present invention, a hard disk structure is provided, including a housing, the housing including a top cover and a bottom plate arranged opposite to each other, the top cover and the bottom plate being connected by side plates, one of the side plates being provided with a locking tongue, the top cover being provided with a through groove, the through groove being provided with a linkage rod, the linkage rod being connected to the locking tongue; by moving the linkage rod, the locking tongue can be moved to allow the locking tongue to be concealed within the housing; the housing is provided with a first reset assembly, the first reset assembly causing the locking tongue to tend to move toward the outside of the housing;

[0006] The base plate is provided with a push plate and a second reset assembly. The end of the push plate near the locking tongue is hinged to the base plate, and the second reset assembly is connected to the push plate so that the push plate tends to rotate in a direction away from the base plate.

[0007] In the above-described hard disk structure, the side plate is provided with a through hole that matches the locking tongue, and the locking tongue slides in conjunction with the through hole;

[0008] The first reset assembly includes a slider and a connecting rod. The slider is slidable within the housing. One end of the connecting rod is hinged to the latch, and the other end of the connecting rod is hinged to the slider. A first helical spring is provided at the end of the slider away from the connecting rod, and the first helical spring contacts the inner wall of the housing. When the latch moves into the housing, the connecting rod pushes the slider to compress the first helical spring.

[0009] In the above-described hard disk structure, the latch slides along a first direction, and the slider slides along a second direction, wherein the first direction and the second direction are perpendicular.

[0010] In the above hard disk structure, there are two sliders arranged symmetrically, and there are two connecting rods that correspond one-to-one with the two sliders.

[0011] In the above-described hard drive structure, a sliding key is provided at the end of the linkage rod away from the locking tongue, and the sliding key is located outside the housing.

[0012] In the above-described hard disk structure, a back plate is provided on the base plate, and a groove is provided on the side of the back plate facing away from the base plate. A rotating shaft is rotatably disposed in the groove, and the push plate is fixedly connected to the rotating shaft.

[0013] In the above-described hard disk structure, the second reset component includes a torsion spring, which is sleeved on the spindle. One free end of the torsion spring is connected to the back plate, and the other free end of the torsion spring is connected to the push plate.

[0014] In the above-described hard disk structure, the backplate is provided with a damping mechanism that can reduce the rotational speed of the spindle.

[0015] In the above-described hard disk structure, the damping mechanism includes a gear fixed on the rotating shaft and a rack adapted to the gear. The bottom of the groove is provided with a guide groove. The rack is located in the guide groove and can move along the guide groove. One end of the rack is provided with a second helical spring, which is located between the end of the rack and the end of the guide groove.

[0016] In the above-described hard disk structure, there are two damping mechanisms arranged symmetrically.

[0017] One of the above-described technical solutions of the present invention has at least one of the following advantages or beneficial effects:

[0018] In this invention, a locking tongue is provided on the housing, and a corresponding locking hole is provided at the position on the chassis for installing the hard drive. When in use, the linkage rod is manually moved to move the locking tongue inward into the housing, so that the locking tongue can be hidden in the housing. After the hard drive is placed into the slot of the chassis, the linkage rod is released, and the first reset component will be activated. The locking tongue will move outward from the housing until the locking tongue is inserted into the locking hole, and the hard drive is fixed.

[0019] When removing the hard drive, manually move the linkage lever to disengage the locking tongue from the locking hole. The push plate then rotates under the drive of the second reset component. The angle between the push plate and the base plate gradually increases, thereby ejecting the hard drive from the chassis slot. Based on this, the hard drive structure has been optimized, which facilitates both securing and removing the hard drive, effectively improving maintenance efficiency. Attached Figure Description

[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0031] Reference Figures 1 to 6 As shown, in one embodiment of the present invention, a hard disk structure includes a housing 1, which includes a top cover 11 and a bottom plate 12 arranged opposite to each other. The top cover 11 and the bottom plate 12 are connected by a side plate 13. Corresponding electronic devices are arranged inside the housing 1 so that the hard disk can realize the storage function.

[0032] One of the side plates 13 is provided with a locking tongue 2, and the top cover 11 is provided with a through groove 111. A linkage rod 112 is provided in the through groove 111. The linkage rod 112 is connected to the locking tongue 2. The through groove 111 allows the linkage rod 112 to move. By moving the linkage rod 112, the locking tongue 2 can be moved. The housing 1 is provided with a first reset component 3. The first reset component 3 makes the locking tongue 2 tend to move towards the outside of the housing 1.

[0033] The chassis is equipped with corresponding locking holes for the hard drive installation position. When in use, manually move the linkage rod 112 to move the locking tongue 2 into the housing 1, so that the locking tongue 2 can be hidden in the housing 1. After the hard drive is placed into the slot of the chassis, release the linkage rod 112, and the first reset component 3 will be activated. The locking tongue 2 will move out of the housing 1 until the locking tongue 2 is inserted into the locking hole, and the hard drive is fixed.

[0034] Meanwhile, the base plate 12 is provided with a push plate 4 and a second reset assembly 5. The end of the push plate 4 near the locking tongue 2 is hinged to the base plate 12, and the second reset assembly 5 is connected to the push plate 4 so that the push plate 4 has a tendency to rotate in a direction away from the base plate 12.

[0035] When the hard drive is not installed, under the action of the second reset component 5, there is a large angle between the push plate 4 and the base plate 12. During the process of pressing the hard drive into the chassis slot, the push plate 4 will be pressed and rotated, making the angle between the push plate 4 and the base plate 12 smaller, and the second reset component 5 will gradually accumulate energy. When removing the hard drive, after manually moving the linkage rod 112 to make the locking tongue 2 leave the locking hole, the push plate 4 will rotate under the drive of the second reset component 5, and the angle between the push plate 4 and the base plate 12 will gradually increase, thereby popping the hard drive out of the chassis slot. Based on this, the hard drive structure is optimized, which not only facilitates the fixing of the hard drive, but also facilitates the removal of the hard drive, effectively improving the efficiency of maintenance.

[0036] In this embodiment, the side plate 13 is provided with a through hole that matches the latch 2, and the latch 2 slides in the through hole; the end of the latch 2 near the outside of the housing 1 is an arc-shaped end, which makes it easy to insert into the lock hole, and the end of the latch 2 away from the outside of the housing 1 is provided with a limiting protrusion to prevent the latch 2 from completely coming out of the through hole.

[0037] The first reset assembly 3 includes a slider 31 and a connecting rod 32. The slider 31 can slide inside the housing 1. The locking tongue 2 slides along a first direction, and the slider 31 slides along a second direction. The first direction is perpendicular to the second direction.

[0038] One end of the connecting rod 32 is hinged to the locking tongue 2, and the other end of the connecting rod 32 is hinged to the slider 31. The slider 31 is provided with a first helical spring 33 at the end away from the connecting rod 32. The first helical spring 33 is in contact with the inner wall of the housing 1.

[0039] When the latch 2 moves into the housing 1, the connecting rod 32 pushes the slider 31 to compress the first helical spring 33; after the linkage rod 112 is released, the first helical spring 33 returns to its original state, pushing the slider 31 to move, thereby allowing the latch 2 to move out of the housing 1.

[0040] In this structure, the internal space of the housing 1 occupied by the first reset component 3 can be minimized, and the housing 1 does not need to be lengthened in the first direction, making the overall structure of the hard drive more compact.

[0041] Preferably, there are two sliders 31 arranged symmetrically, and two connecting rods 32 corresponding one-to-one with the two sliders 31. Therefore, the first reset assembly 3 has two first helical springs 33, which provide greater elastic force and can make the locking tongue 2 firmly locked in the lock hole.

[0042] Specifically, the slider 31 is provided with a guide protrusion, and the inner wall of the housing 1 is provided with a sliding groove that cooperates with the guide protrusion. The slider 31 slides in cooperation with the sliding groove, which can both position the slider 31 and assist the slider 31 in moving.

[0043] In this embodiment, a sliding key 113 is provided at the end of the linkage rod 112 away from the locking tongue 2. The sliding key 113 is located outside the housing 1. With the sliding key 113, it is easier to move the linkage rod 112. The sliding key 113, the linkage rod 112 and the locking tongue 2 move synchronously. Pushing the sliding key 113 can move the locking tongue 2.

[0044] In this embodiment, a back plate 6 is provided on the bottom plate 12, and a groove 61 is provided on the side of the back plate 6 facing away from the bottom plate 12. A rotating shaft 62 is rotatably arranged in the groove 61, and the push plate 4 is fixedly connected to the rotating shaft 62.

[0045] After the hard drive is installed in the chassis slot, the push plate 4 will be pressed into the groove 61. The back plate 6 can hide the push plate 4, allowing the back plate 6 to directly contact the chassis slot, making the hard drive installation more flat.

[0046] In this embodiment, the second reset component 5 includes a torsion spring, which is sleeved on the rotating shaft 62. One free end of the torsion spring is connected to the back plate 6, and the other free end of the torsion spring is connected to the push plate 4.

[0047] When the hard drive is not installed, there is a large angle between the push plate 4 and the base plate 12 under the action of the torsion spring. During the process of pressing the hard drive into the chassis slot, the push plate 4 will be compressed, thereby rotating the shaft 62, torsion spring, and reducing the angle between the push plate 4 and the base plate 12. The torsion spring gradually stores energy. When removing the hard drive, after manually moving the linkage rod 112 to make the locking tongue 2 leave the locking hole, the torsion spring will return to its original position. The push plate 4 will rotate under the drive of the torsion spring, and the angle between the push plate 4 and the base plate 12 will gradually increase, thereby popping the hard drive out of the chassis slot.

[0048] In this embodiment, the back plate 6 is provided with a damping mechanism 7 that can reduce the rotational speed of the rotating shaft 62;

[0049] The damping mechanism 7 includes a gear 71 fixed on a rotating shaft 62 and a rack 72 adapted to the gear 71. The bottom of the groove 61 is provided with a guide groove 63. The rack 72 is located in the guide groove 63 and can move along the guide groove 63. One end of the rack 72 is provided with a second helical spring 73, which is located between the end of the rack 72 and the end of the guide groove 63.

[0050] As the angle between the push plate 4 and the base plate 12 gradually increases, that is, when the hard drive ejects, the push plate 4 gradually rotates, the shaft 62 rotates along with it, and the gear 71 rotates along with the shaft 62. The gear 71 pushes the rack 72 to move, and the rack 72 moves in the direction close to the second helical spring 73 to compress the second helical spring 73. During this process, the elastic force of the second helical spring 73 gradually increases, thereby reducing the moving speed of the rack 72, and thus slowing down the rotation speed of the shaft 62. The rotation speed of the push plate 4 will also slow down. Based on this, the hard drive can be prevented from ejecting rapidly and falling out accidentally.

[0051] In this embodiment, a cover plate is provided on the guide groove 63, which covers at least half of the guide groove 63 to prevent the rack 72 and the second helical spring 73 from falling out.

[0052] In this embodiment, a positioning rod is provided at one end of the rack 72 near the second helical spring 73. The second helical spring 73 can be fitted onto the positioning rod. The length of the positioning rod is not too long to avoid affecting the movement of the rack 72.

[0053] In this embodiment, there are two damping mechanisms 7 arranged symmetrically to further reduce the speed at which the push plate 4 ejects the hard drive.

[0054] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
