Description

Technical Field

[0001] This disclosure relates to the field of home storage technology, and in particular to a handle structure, hard drive rack, and storage device. Background Technology

[0002] With the development of technology, home NAS (Network Attached Storage) storage devices have gradually been widely used.

[0003] Currently, home NAS storage devices often have handles on the hard drive racks for unlocking. When inserting the hard drive rack into the hard drive bay, you need to hold the handle at all times to keep it unlocked, allowing the rack to smoothly enter the bay.

[0004] This means that users need to hold the handle on the lever at all times while inserting the hard drive bracket into the hard drive bay, making the operation rather inconvenient. Summary of the Invention

[0005] This disclosure provides a handle structure, a hard drive rack, and a storage device, which can solve the aforementioned technical problems existing in related technologies. The technical solution is as follows: In a first aspect, a handle structure is provided, the handle structure including a housing and a locking component; The housing has a receiving cavity; The locking assembly includes a first elastic element, a locking element, and a handle. The first elastic element is located within the receiving cavity. A first end of the locking element is located within the receiving cavity and in contact with the first elastic element. A second end of the locking element is located outside the receiving cavity. The second end is used to drive the first end to resist the elastic movement of the first elastic element after being squeezed. The locking element has a first protrusion. The handle is rotatably connected to the housing and located on the side of the first protrusion. The handle is used to squeeze the first protrusion when rotating, so as to drive the first end to resist the elastic movement of the first elastic element.

[0006] In some possible implementations, the second end has a guide surface located on the side of the second end away from the handle, the guide surface being designed to be compressed.

[0007] In some possible implementations, the handle has a second protrusion located on the side of the first protrusion near the second end, and is used to press the first protrusion when the handle is rotated.

[0008] In some possible implementations, the first protrusion has a first guide arc surface, and the second protrusion has a second guide arc surface, the second guide arc surface being used to abut against the first guide arc surface.

[0009] In some possible implementations, the locking assembly further includes a second elastic element located between the handle and the housing, the second elastic element being used to hold the handle in its initial position.

[0010] In some possible implementations, the housing has a connecting rod, and the second elastic element is a double torsion spring sleeved on the connecting rod. The double torsion spring has a first torsion arm, a second torsion arm, and a third torsion arm. The second torsion arm is located between the first torsion arm and the third torsion arm and is engaged with the connecting rod. The first torsion arm and the third torsion arm abut against the housing.

[0011] In some possible implementations, the handle has a first rotational position and a second rotational position; The housing has a first abutment and a second abutment on the side near the handle. The first abutment is used to abut against the handle when the handle is in the first rotation position. The second abutment is arranged at an angle relative to the first abutment and is used to abut against the handle when the handle is in the second rotation position.

[0012] In some possible implementations, the first elastic element is a spring that abuts against the housing, and the first end has a plug portion that is inserted into the spring.

[0013] In a second aspect, a hard drive rack is provided, the hard drive rack including a frame and a handle structure provided by the first aspect or any possible implementation thereof, the frame having a hard drive mounting portion, and the handle structure being connected to the frame.

[0014] Thirdly, a storage device is provided, the storage device including a device body and a hard disk rack provided in the second aspect above, the device body including a main housing and a hard disk compartment, the hard disk compartment being fixed inside the main housing, and the hard disk rack being inserted into the hard disk compartment.

[0015] In some possible implementations, the device body further includes a buffer structure located between the bottom wall of the hard disk compartment and the hard disk rack.

[0016] In some possible implementations, the buffer structure is fixedly connected to the bottom wall of the hard disk compartment.

[0017] In some possible implementations, the buffer structure includes a plate and a plurality of spring tabs fixed to the plate, the plurality of spring tabs protruding toward the hard disk frame and abutting against the hard disk frame.

[0018] In some possible implementations, the main housing has an opening for the hard drive rack to pass through; The device body also includes a cover plate that covers the opening and is connected to the main housing. The outer peripheral wall of the cover plate has a light-shielding layer.

[0020] The beneficial effects of the technical solution provided in this disclosure include at least the following: During the process of inserting the hard drive rack into the hard drive compartment, releasing the handle will cause the handle to return to its original position under the force of the elastic element. When the second end of the locking element is squeezed, it will cause the first end of the locking element to resist the elastic force of the first elastic element, thereby switching the handle bar to the unlocked state. Therefore, during the process of inserting the hard drive rack into the hard drive compartment, it is not necessary to hold the handle on the handle at all times, which can greatly improve the convenience of user operation.

[0025] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This disclosure provides a handle structure 01. For example... Figure 1 As shown, the handle structure 01 includes a housing 1 and a locking assembly 2. Combined with... Figure 1 , Figure 2 As shown, the housing 1 has a receiving cavity. The locking assembly 2 includes a first elastic member 21, a locking member 22, and a handle 23. The first elastic member 21 is located inside the receiving cavity. The first end 221 of the locking member 22 is located inside the receiving cavity and in contact with the first elastic member 21. The second end 222 of the locking member 22 is located outside the receiving cavity. The second end 222 is used to drive the first end 221 to resist the elastic movement of the first elastic member 21 after being squeezed. The locking member 22 has a first protrusion 223. The handle 23 is rotatably connected to the housing 1 and is located on the side of the first protrusion 223. The handle 23 is used to squeeze the first protrusion 223 when rotated, so as to drive the first end 221 to resist the elastic movement of the first elastic member 21.

[0028] Using the handle structure 01 provided in this embodiment, when inserting the hard drive rack 02 into the hard drive compartment 42, releasing the handle 23 will reset the handle 23 under the force of the elastic member. When the second end 222 of the locking member 22 is squeezed, it will drive the first end 221 of the locking member 22 to resist the elastic force of the first elastic member 21, thereby switching the handle bar to the unlocked state. Therefore, when inserting the hard drive rack 02 into the hard drive compartment 42, it is not necessary to hold the handle 23 on the handle at all times, and the hard drive rack 02 can be inserted into the hard drive compartment 42, thereby greatly improving the convenience of user operation.

[0029] like Figure 4 As shown, when the handle structure 01 provided in this embodiment is used in the hard disk rack 02, before pulling the hard disk rack 02 out of the hard disk compartment 42, it is combined with... Figure 2 , Figure 4As shown, by rotating the handle 23, the handle 23 presses against the first protrusion 223, causing the first end 221 to resist the elastic force of the first elastic member 21, thereby switching the handle structure 01 to the unlocked state, and then the hard drive rack 02 can be pulled out; during the process of inserting the hard drive rack 02 into the hard drive compartment 42, the handle 23 can be rotated to the initial state, and then the hard drive rack 02 can be directly pushed into the hard drive compartment 42. When the second end 222 of the locking member 22 is squeezed, it will cause the first end 221 of the locking member 22 to resist the elastic force of the first elastic member 21, thereby switching the handle structure 01 to the unlocked state, and then the hard drive rack 02 can be pushed into the hard drive compartment 42; after the hard drive rack 02 is pushed into the hard drive compartment 42, under the action of the elastic member, the second end 222 will return to the initial position, thereby switching the handle structure 01 to the locked state, and locking the hard drive rack 02.

[0030] like Figure 3 As shown, in some embodiments, the second end 222 has a guide surface 2221 located on the side of the second end 222 away from the handle 23, and the guide surface 2221 is used to be squeezed.

[0031] Among them, such as Figure 4 As shown, during the process of pushing the hard drive rack 02 into the hard drive compartment 42, the hard drive rack 02 mainly moves along the first direction. When the hard drive rack 02 moves to the point where the second end 222 is squeezed, the guide surface 2221 can decompose the force on the second end 222 into a first component force in the first direction and a second component force in the second direction perpendicular to the first direction. Thus, under the action of the second component force, the second end 222 can move in the second direction to switch the handle structure 01 to the unlocked state, thereby pushing the hard drive rack 02 into the hard drive compartment 42.

[0032] Thus, by setting a guide surface 2221 at the second end 222, the second end 222 can be squeezed more easily, so as to ensure that the hard disk rack 02 can be pushed into the hard disk compartment 42 more smoothly.

[0033] Optionally, the guide surface 2221 can be a chamfered surface.

[0034] Of course, in some other embodiments, the outer side of the main housing 41 of the storage device 03 is provided with a guide slope, and the second end 222 is not provided with a guide surface 2221, which can also ensure that the hard disk rack 02 can be pushed into the hard disk compartment 42.

[0035] like Figure 2 As shown, in some embodiments, the handle 23 has a second protrusion 231 located on the side of the first protrusion 223 near the second end 222, and is used to press the first protrusion 223 when the handle 23 is rotated.

[0036] Thus, through the cooperation of the second protrusion 231 and the first protrusion 223, the first protrusion 223 can be squeezed by the handle 23 to drive the locking member 22 to move, thereby realizing the switching of the state of the locking member 22. Furthermore, through the second protrusion 231, interference between the locking member 22 and the handle 23 can be avoided when the handle 23 is in the initial position and the second end 222 is squeezed.

[0037] like Figure 2 As shown, in some embodiments, the first protrusion 223 has a first guide arc surface 2231, and the second protrusion 231 has a second guide arc surface 2311, the second guide arc surface 2311 being used to abut against the first guide arc surface 2231.

[0038] Thus, when the handle 23 is rotated, the second protrusion 231 will rotate with the handle 23. Through the first guide arc surface 2231 and the second guide arc surface 2311, the first protrusion 223 and the second protrusion 231 can slide relative to each other along the two guide arc surfaces, thereby improving the smoothness of the rotation of the handle 23.

[0039] Combination Figure 2 , Figure 3 As shown, in some embodiments, the locking assembly 2 further includes a second elastic member 24 located between the handle 23 and the housing 1, the second elastic member 24 being used to hold the handle 23 in the initial position.

[0040] Thus, after the user releases the handle 23, the handle 23 can be reset under the action of the first elastic element 21 and the second elastic element 24, eliminating the need for manual reset and greatly improving the convenience of resetting the handle 23. Furthermore, when the second end 222 is compressed, the second elastic element 24 can hold the handle 23 in its initial position, thereby preventing the handle 23 from shaking.

[0041] In addition, when the user pulls the handle 23 to rotate, the second elastic element 24 can provide the user with a damping sensation, thereby providing feedback to the user and improving the user experience.

[0042] like Figure 3 As shown, in some embodiments, the housing 1 has a connecting rod 11, and the second elastic element 24 is a double torsion spring. The double torsion spring is sleeved on the connecting rod 11. The double torsion spring has a first torsion arm 241, a second torsion arm 242 and a third torsion arm 243. The second torsion arm 242 is located between the first torsion arm 241 and the third torsion arm 243 and is engaged with the connecting rod 11. The first torsion arm 241 and the third torsion arm 243 respectively abut against the housing 1.

[0043] The double torsion spring structure exhibits very small reaction torque on the external frame or mounting point, resulting in relatively low strength requirements for the mounting structure and simplifying the structural design of the handle structure 01. Furthermore, the double torsion spring structure provides a relatively stable torque, enabling the handle 23 to move more stably.

[0044] Alternatively, the handle 23 is hinged to the connecting rod 11.

[0045] Combination Figure 1 , Figure 3 As shown, in some embodiments, the handle 23 has a first rotation position and a second rotation position. The housing 1 has a first abutment portion 12 and a second abutment portion 13 on the side near the handle 23. The first abutment portion 12 is used to abut against the handle 23 when the handle 23 is in the first rotation position. The second abutment portion 13 is arranged at an angle relative to the first abutment portion and is used to abut against the handle 23 when the handle 23 is in the second rotation position.

[0046] Thus, when the handle structure 01 is in the locked position, the first abutting part 12 abuts against the handle 23, and when the handle structure 01 is in the unlocked position, the second abutting part 13 abuts against the handle 23, thereby enabling the first abutting part 12 and the second abutting part 13 to limit the handle 23 at different positions.

[0047] Optionally, the dividing point between the first abutting part 12 and the second abutting part 13 is located at the connecting rod 11, that is, at the hinge position between the handle 23 and the housing 1.

[0048] like Figure 3 As shown, in some embodiments, the first elastic element 21 is a spring, which abuts against the housing 1, and the first end 221 has a plug portion 2211, which is plugged into the spring.

[0049] Thus, when the handle 23 is released and the first end 221 is not compressed, the first end 221 can be reset under the action of the spring. The spring has a relatively simple structure, which reduces the structural complexity of the handle structure 01 and reduces the assembly difficulty of the handle mechanism.

[0050] Optionally, the first elastic element 21 is always under compression.

[0051] Based on the same concept, this disclosure also provides a hard disk rack 02. For example... Figure 5 As shown, the hard drive rack 02 includes a frame 3 and the handle structure 01 provided above. The frame 3 has a hard drive mounting part, and the handle structure 01 is connected to the frame 3.

[0052] Thus, when inserting the hard drive bracket 02 into the hard drive compartment 42, releasing the handle 23 will reset the handle 23 under the force of the elastic element. When the second end 222 of the locking element 22 is squeezed, it will cause the first end 221 of the locking element 22 to resist the elastic force of the first elastic element 21, thereby switching the handle bar to the unlocked state. Therefore, when inserting the hard drive bracket 02 into the hard drive compartment 42, it is not necessary to hold the handle 23 on the handle at all times, and the hard drive bracket 02 can be inserted into the hard drive compartment 42, which can greatly improve the convenience of user operation.

[0053] Combination Figure 5 , Figure 6 As shown, the hard drive rack 02 also includes a buffer assembly 6 and a connector 7. The buffer assembly 6 includes a first elastic pad 61 and a second elastic pad 62. The first elastic pad 61 is located on the bottom wall of the hard drive rack 02 and between the hard drive rack 02 and the hard drive 5, thereby buffering the hard drive 5 on the bottom wall of the hard drive rack 02. The second elastic pad 62 is located on the side wall of the hard drive rack 02 and between the hard drive rack 02 and the hard drive 5, thereby buffering the hard drive 5 on the side wall of the hard drive rack 02. The connector 7 passes through the hard drive rack 02 and connects to the hard drive 5 to secure the hard drive 5.

[0054] Thus, the buffer component 6 can buffer the hard disk 5 to reduce the possibility of damage to the hard disk 5.

[0055] Optionally, the buffer assembly 6 includes a plurality of first elastic pads 61 and a plurality of second elastic pads 62. The plurality of first elastic pads 61 are spaced apart on the bottom wall of the hard disk rack 02, and the plurality of second elastic pads 62 are spaced apart on two opposite side walls of the hard disk rack 02. The connector 7 passes through the second elastic pads 62 and is connected to the hard disk 5 to position the second elastic pads 62.

[0056] Based on the same concept, this disclosure also provides a storage device 03. In conjunction with... Figure 7 , Figure 8 As shown, the storage device 03 includes a device body 4 and the hard disk rack 02 provided above. The device body 4 includes a main housing 41 and a hard disk compartment 42. The hard disk compartment 42 is fixed inside the main housing 41, and the hard disk rack 02 is inserted into the hard disk compartment 42.

[0057] like Figure 4As shown, when the storage device 03 provided in this embodiment is used to insert the hard disk bracket 02 into the hard disk compartment 42, the handle 23 is released and the handle 23 will be reset under the force of the elastic member. When the second end 222 of the locking member 22 is squeezed, the first end 221 of the locking member 22 will resist the elastic force of the first elastic member 21, thereby switching the handle bar to the unlocked state. Therefore, when inserting the hard disk bracket 02 into the hard disk compartment 42, it is not necessary to hold the handle 23 on the handle at all times, and the hard disk bracket 02 can be inserted into the hard disk compartment 42, thereby greatly improving the convenience of user operation.

[0058] Optionally, the hard drive bay 42 is cage-shaped, with porous sidewalls to facilitate heat dissipation for the hard drive 5.

[0059] Combination Figure 8 , Figure 9 As shown, in some embodiments, the device body 4 further includes a buffer structure 43, which is located between the bottom wall of the hard disk compartment 42 and the hard disk rack 02.

[0060] Thus, after the hard disk bracket 02 is inserted into the hard disk bay 42, the buffer structure 43 can cushion the hard disk bracket 02 at the bottom, thereby reducing the vibration of the hard disk 5 and thus reducing the possibility of damage to the hard disk 5.

[0061] like Figure 9 As shown, in some embodiments, the buffer structure 43 is fixedly connected to the bottom wall of the hard disk compartment 42.

[0062] This prevents the buffer structure 43 from shifting during use, thereby improving the stability of the storage device 03 during use.

[0063] like Figure 10 As shown, in some embodiments, the buffer structure 43 includes a plate 431 and a plurality of spring pieces 432 fixed to the plate 431. The plurality of spring pieces 432 protrude toward the hard disk frame 02 and abut against the hard disk frame 02.

[0064] Thus, by utilizing the structure of the plate 431 and the spring clip 432, the hard drive cage 02 is cushioned. Compared to using a single elastic pad, this avoids excessive damping during the insertion of the hard drive cage 02 into the hard drive bay 42, thereby improving the smoothness of the hard drive cage 02's movement. Furthermore, this method only requires the plate 431 to have a smaller thickness to achieve the cushioning effect, thus saving internal space in the hard drive bay 42 and reducing the overall size of the storage device 03.

[0065] Optionally, the plate 431 and the multiple spring pieces 432 are both made of metal, and the plate 431 has multiple receiving holes to accommodate the spring pieces 432 when they deform.

[0066] like Figure 11 As shown, in some embodiments, the main housing 41 has an opening 411 for the hard disk rack 02 to pass through. The device body 4 also includes a cover plate 44 that covers the opening 411 and is connected to the main housing 41, and the outer peripheral wall of the cover plate 44 has a light-shielding layer 408.

[0067] In this way, the outer peripheral wall of the cover plate 44 is opaque, thereby preventing the light beam inside the storage device 03 from leaking out through the outer peripheral wall of the cover plate 44, thus reducing the possibility of the storage device 03 causing significant light pollution.

[0068] Of course, the surface of the cover plate 44 near the hard drive bay 42 also has a light-shielding layer 408, so as to reduce the possibility of the storage device 03 causing greater light pollution.

[0069] Optionally, the cover plate 44 is a magnetic cover plate 44. This improves the ease of connection between the cover plate 44 and the main housing 41.

[0070] In some embodiments, the light-shielding layer 408 is a reflective layer.

[0071] This improves the overall structure of the storage device 03, making the cover plate 44 more aesthetically pleasing and enhancing the overall appearance of the storage device 03.

[0072] Optionally, the light-shielding layer 408 may be a silver or gray reflective layer, and this disclosure does not limit this.

[0073] Combination Figure 12 As shown, this disclosure also provides a possible method for processing the above-mentioned cover plate 44, as follows: Step 1: Print the logo (mark) 402 on the back of the mirror high-gloss composite board 401.

[0074] Step 2: Set a brightening layer 403 on the back of the mirror high-gloss composite material 401. For example, the brightening layer can be formed by indium plating through NCVM (Non-conductive vacuum metallization) or optical plating.

[0075] Step 3: Set a semi-transparent layer 404 on the back of the mirror high-gloss composite board 401. For example, the semi-transparent layer 404 can be a semi-transparent medium gray silver ink layer or a semi-transparent gray ink layer.

[0076] Step 4: Set a light-blocking layer 405 on the back of the mirror high-gloss composite board 401. For example, it can be a black base ink layer, and the light hole area can be hollowed out to let light pass through.

[0077] Step 5: Cross-cut the mirror-finish high-gloss composite board 401 to obtain sheet 406.

[0078] Step 6: Using CNC (Computerized Numerical Control) machining technology, remove the tool marks on the side of sheet 406 to obtain a smooth side surface layer 407.

[0079] Step 7: Spray a light-shielding layer 408 around the side and back of the sheet 406, for example, spraying silver or gray paint.

[0080] Step 8: Perform CNC machining on the front side of sheet 406 to obtain an R-angle of 409.

[0081] This processing method increases the overall coordination of the process and improves the overall texture of the cover plate 44, making it opaque from the sides.

[0082] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein.
