DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.”
Referring to FIGS. 1-3 and 7, a locking assembly 10 is used to lock an electronic device 20 in a communication apparatus 30, and to remove the electronic device 20 from the communication apparatus 30. In the illustrated embodiment, the electronic device 20 may be a removable power supply, a removable hard disk or a removable fan, which is used in computers, servers, redundant arrays of independent disks (RAIDs), and other communication apparatuses.
In particular, the electronic device 20 is accommodated in a housing structure 12, and the housing structure 12 is engaged with the locking assembly 10. The combination of the housing structure 12, the electronic device 20 and the locking assembly 10 is removably installed in the communication apparatus 30.
The locking assembly 10 comprises a pair of locking parts 14, a sliding part 16, and a handle 18. The pair of locking parts 14 and the sliding part 16 are mounted on the housing structure 12. The handle 18 is securely mounted on the sliding part 16 so that the sliding part 16 is driven to move in the housing structure 12 by pushing or pulling the handle 18.
The housing structure 12 comprises a front board 120, a pair of side boards 122, and a bottom board 124. The pair of side boards 122 perpendicularly extend from two sides of the bottom board 124 to be parallel with each other, and the front board 120 perpendicularly extends from an end of the bottom board 124 to interconnect the pair of side boards 122. Therefore, the front board 120, the pair of side boards 122 and the bottom board 124 collectively form a receiving space 126 to receive the electronic device 20. In the illustrated embodiment, the front board 120, the pair of side boards 122 and the bottom board 124 are integrally formed. In other embodiments, the front board 120, the pair of side boards 122 and the bottom board 124 are separately formed, and are then assembled together by a mechanical mounting method to form the housing structure 12.
The front board 120 defines a pair of first through holes 1200 to engagingly receive the handle 18, and comprises a first protruding portion 1202. The first protruding portion 1202 protrudes from the front board 120 into the receiving space 126, and is between the pair of first through holes 1200. Each of the pair of side boards 122 defines at least one latching hole 1220 and a plurality of first fixing holes 1222. The plurality of first fixing holes 1222 are provided at an end of the corresponding side board 122 contiguous with the front board 120, to enable one corresponding locking part 14 to be engaged with the side board 122. In the illustrated embodiment, each side board 122 defines two latching holes 1220. Each latching hole 1220 is substantially strip-shaped, i.e., a slot. The two latching holes 1220 are provided on a side of the plurality of first fixing holes 1222 away from the front board 120.
In other embodiments, the locking assembly 10 comprises only one locking part 14, and only one of the pair of side boards 122 of the housing structure 12 need define at least one latching hole 1220 to engagingly receive the locking part 14. In still other embodiments, there may be only one latching hole 1220, or more than two latching holes 1220, per side board 122.
Each of the locking parts 14 comprises a fixing portion 140, a connecting portion 142, at least one latching portion 144, and a guiding portion 146. The fixing portion 140 and the guiding portion 146 are provided on two opposite front and rear sides of the connecting portion 142, respectively. In the illustrated embodiment, there are two latching portions 144. The latching portions 144 extend laterally outward from top and bottom sides of the connecting portion 142, respectively.
The fixing portion 140 defines a plurality of second fixing holes 1400, corresponding to the plurality of first fixing holes 1222 of the respective side board 122. A plurality of tightening parts (or fastening parts) 13, such as bolts, screws or rivets, pass through the corresponding first fixing holes 1222 and are engaged in the corresponding second fixing holes 1400, to securely fix the locking part 14 on the corresponding side board 122 in the receiving space 126. For example, when the tightening parts 13 are screws, the tightening parts 13 pass through the corresponding first fixing holes 1222 and are threadedly engaged in the corresponding second fixing holes 1400. The connecting portion 142 extends from and is coplanar with the fixing portion 140. In the illustrated embodiment, the connecting portion 142 and the fixing portion 140 cooperatively form a generally T-shaped configuration.
The latching portions 144 extend from the top and bottom sides of the connecting portion 142 towards and through the corresponding side board 122. In particular, each latching portion 144 comprises a bevel edge 1442. The bevel edge 1442 is inclined relative to the connecting portion 142, and extends away from the sliding part 16 to engage in the corresponding latching hole 1220. In the illustrated embodiment, each of the latching portions 144 is substantially triangle-shaped. In other embodiments, the at least one latching portion 144 is substantially trapezium-shaped. The guiding portion 146 obliquely extends from a rear of the connecting portion 142 in a direction away from the fixing portion 140. In particular, the guiding portion 146 is bent obliquely inward from the connecting portion 142, away from the corresponding side board 122. Thus, the guiding portion 146 and the pair of latching portions 144 are configured at two opposite outer and inner sides of the connecting portion 142, respectively.
In the illustrated embodiment, the fixing portion 140, the connecting portion 142, the at least one latching portion 144 and the guiding portion 146 are integrally formed as a single monolithic body of the same material. For example, the locking part 14 can be formed by stamping a continuous metal plate.
The number of latching holes 1220 of each side board 122 is equal to the number of latching portions 144 of each locking part 14. In the illustrated embodiment, the number is two. In other embodiments, the number can be only one, or three, or another desired number.
In assembly, the plurality of tightening parts 13 pass through the corresponding first fixing holes 1222 and are engaged in the corresponding second fixing holes 1400 to securely fix the locking parts 14 on the corresponding side boards 122. The latching portions 144 movably engage in the latching holes 1220, so that both the fixing portion 140 and the connecting portion 142 of each locking part 14 abut against the corresponding side board 122. Thereby, a gap is formed between the guiding portion 146 of the locking part 14 and the corresponding side board 122, to receive the sliding part 16 (this is described in more detail below).
Referring to FIG. 4, the sliding part 16 is movably mounted in the receiving space 126, and comprises a sliding portion 162, a pair of resisting portions 164 and an urging portion 166. The sliding portion 162 abuts against the bottom board 124 of the housing structure 12 such that the sliding part 16 can stably slide in the receiving space 126. The pair of resisting portions 164 are perpendicularly bent from two sides of the sliding portion 162, and abut against the corresponding side boards 122 in positions contiguous with the guiding portions 146 of the locking parts 14. Therefore, the pair of locking parts 14 is positioned between the front board 120 and the sliding part 16. Each of the pair of resisting portions 164 has a resisting surface 1640 facing the corresponding locking part 14. The resisting surface 1640 urges the bevel edge 1442 of the locking part 14 to elastically deform the locking part 14.
The urging portion 166 is perpendicularly bent from the sliding portion 162, is positioned generally between the pair of resisting portions 164, defines a pair of second through holes 1660, and comprises a second protruding portion 1662. The pair of second through holes 1660 are opposite to the pair of first through holes 1220, to provide for engagement of the sliding part 16 with the handle 18. The second protruding portion 1662 is positioned between the pair of second through holes 1660, and protrudes outwardly from the urging portion 166 towards the front board 120 to be opposite to the first protruding portion 1202.
In the illustrated embodiment, the sliding portion 162, the pair of resisting portions 164 and the urging portion 166 are integrally formed as a single monolithic body of the same material. For example, the sliding part 16 can be formed by stamping, pressing, bending and/or otherwise processing a continuous metal plate.
The handle 18 comprises a holding portion 180, and a pair of drawing poles 182 perpendicular bent from two opposite ends of the holding portion 180. A pair of screwing holes 184 is defined in ends of the drawing poles 182, respectively.
The locking assembly 10 further comprises an elastic element 15 to reposition the sliding part 16 to an original position. The elastic element 15 is mounted between the front board 120 and the sliding part 16 to elastically connect the sliding part 16 with the housing structure 12. For example, the elastic element 15 is a coil spring. Two ends of the elastic element 15 are fixed on the first protruding portion 1202 and the second protruding portion 1662, to elastically connect the sliding part 16 with the housing structure 12. In other embodiments, the elastic element 15 is a torsion spring or a leaf spring.
In assembly, the sliding part 16 is received in the receiving space 126, with the sliding portion 162 abutting against the bottom board 124, the pair of resisting portions 164 abutting against the corresponding side boards 122, and the urging portion 166 facing towards the front board 120. The pair of drawing poles 182 pass through the corresponding first through holes 1200 and the corresponding second through holes 1660 respectively. A pair of tightening screws 17 is screwed in the corresponding screwing holes 184 to securely mount the corresponding drawing poles 182 on the urging portion 166. Thereby, the handle 18 is firmly fixed on the sliding part 16.
Referring to FIG. 5 and FIG. 6, in operation of the locking assembly 10, the holding portion 180 of the handle 18 is pulled by a user to drive the sliding part 16 to move towards the locking parts 14, with the pair of drawing poles 182 sliding in the corresponding first through holes 1200. Each resisting portion 164 moves towards the gap formed between the corresponding guiding portion 146 and the corresponding side board 122, and the resisting surface 1640 interferingly urges the bevel edges 1442. Thus the locking part 14 elastically deforms inward and the latching portions 144 withdraw inward toward and at least partly into the receiving space 126. In this process, free ends of the latching portions 144 may remain in the corresponding latching holes 1220, or the latching portions 144 may completely disengage from the corresponding latching holes 1220. In addition, the elastic element 15 is compressed.
As described above, when the two pairs of latching portions 144 are disengaged from the corresponding latching holes 1220 by the corresponding resisting portions 164 urging the latching portions 144, the elastic element 15 is compressed. Then when the user releases his/her pressure on the holding portion 180, the elastic element 15 decompresses and drives the sliding part 16 inward. The sliding part 16 is urged to move away from the locking parts 14, and the resisting portions 164 disengage from the corresponding latching portions 144, as shown in FIG. 1.
Referring to FIG. 7 and FIG. 8, the locking assembly 10 is used to lock the electronic device 20 received in the receiving space 126 of the housing structure 12 onto the communication apparatus 30. The combination of the housing structure 12, the electronic device 20 and the locking assembly 10 is hereinafter sometimes referred to as a “removable module” (not labeled).
The communication apparatus 30 comprises an enclosure 32 and a plurality of clapboards 34. The clapboards 34 are mounted in the enclosure 32, and are spaced from each other to form a plurality of receiving portions (or receptacles) 36. Each of the receiving portions 36 is bordered on two sides by two clapboards 34, and is used to receive one respective removable module. Each of the clapboards 34 defines at least one locking hole 340 opposite to the at least one latching hole 1220 of a corresponding adjacent side board 122. In the present embodiment, each clapboard 34 defines two locking holes 340 in each of two opposite sides thereof. The latching portions 144 of the locking parts 14 of the housing structure 12 are latched into the corresponding latching holes 1220 and the corresponding locking holes 340 of two corresponding clapboards 34 to lock the housing structure 12 in a selected one of the receiving portions 36. Thereby, the electronic device 20 is securely mounted in the communication apparatus 30. In the present embodiment, at least two housing structures 12 with electronic devices 20 received therein can be parallelly mounted in the communication apparatus 30.
When the electronic device 20 needs to be removed from the communication apparatus 30, the handle 18 is pulled by a user to drive the sliding part 16 to move towards the locking parts 14. The resisting portions 164 enter the gaps between the guiding portions 146 and the corresponding side boards 122 and the resisting surfaces 1640 interferingly urge the corresponding bevel edges 1442 such that the latching portions 144 disengage from the corresponding locking holes 340. The elastic element 15 is thus compressed; and the housing structure 12 is then slid out from the receiving portion 36 to take the electronic device 20 out of the communication apparatus 30. Then when the user releases his/her pressure on the handle 18, the elastic element 15 decompresses and drives the sliding part 16 to move inward away from the locking parts 14. Thus the resisting portions 164 disengage from the guiding portions 146 and the elastic element 15 returns to an original uncompressed (natural) state.
When the electronic device 20 (which is received in the receiving space 126 of the housing structure 12) is to be mounted back into the communication apparatus 30, the handle 18 is pushed by the user to drive the sliding part 16 to move away from the locking parts 14 and to stretch the elastic element 15. The housing structure 12 is slid into the receiving portion 36 until the latching portions 144 are latched into the latching holes 1220 and the locking holes 340. Then when the user releases his/her pressure on the handle 18, the elastic element 15 recoils, and the sliding part 16 moves back part of the way towards the locking parts 14 until the elastic element 15 returns to an original unstretched (natural) state.
Although the features and elements of the present disclosure are described as embodiments in particular combinations, each feature or element can be used alone or in other various combinations within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
