The above described features and advantages of the present invention will be more apparent from the following description.

1 is a block diagram of a portion of a server in accordance with an embodiment of the present invention. Referring to FIG. 1 , in the embodiment, the server 10 includes a rack 100 , a chassis 200 , and a pair of latch structures 300 , 400 disposed on the chassis 200 . The chassis 200 is movably assembled to the frame 100, which is adapted to move in or out of the frame 100 along an axis L1. Here, in order to clearly recognize the relationship between the above components, only a part of the rack 100 and a chassis 200 are shown as representative. Moreover, related electronic devices (not shown) disposed in the chassis 200 of the server 10 are already visible in the prior art and will not be further described herein.

In this embodiment, the latch structures 300 and 400 are symmetrically disposed on opposite sides of one of the front panels 210 of the chassis 200, and are located adjacent to the rack 100. Structure 300 is described.

2 is an exploded view of a portion of the components of the server of FIG. 1. Referring to FIG. 1 and FIG. 2 simultaneously, the chassis 200 further has a side plate 220 adjacent to the front plate 210, and the latch structure 300 includes a latching member 310 and a pushing member 320. The fastening member 310 is an elastic plate member including a body 312 and a buckle portion 314 disposed on the body 312 and extending from the body 312 toward the side plate 220. The main body 312 has a fixed end E1 and a free end E2, wherein the fixed end E1 can be fixed to the inner surface S1 of the side plate 220 by riveting and locking, and the buckle portion 314 is, for example, a hook near the free end E2. The free end E2 passes through the inside of the chassis 200 and protrudes outside the front plate 210. When the body 312 is unstressed, the buckle portion 314 passes through the inner surface S1 of the side plate 220 and protrudes from the outer surface S2 of the side plate 220, and is thereby buckled to the frame 100 to fix the chassis 200 to the frame. The effect within 100.

Furthermore, the pusher member 320 is coupled to the free end E2 of the latching member 310, and since the front panel 210 has a lateral opening 212 at the projection of the free end E2, the pusher member 320 is adapted to be forced to bias the member 320 (ie, The free end E2) moves relative to the chassis 200 (ie, the direction D1 is illustrated), and while the free end E2 moves toward the direction D1, the body 312 also drives the latching portion 314 to move toward the inside of the chassis 200, and thus does not move in the latching portion 314. When the outer surface S2 of the side panel 220 is inserted, the buckle relationship between the panel and the chassis 100 is released to facilitate the user to remove the chassis 200 from the rack 100.

The locking structure 300 further includes a fixing member 330 and a handle 340 for the user to operate the above-mentioned unfastening relationship and the removal of the chassis in a more labor-saving and convenient manner. The fixing member 330 can be fixedly attached to the front plate 210 of the chassis 200 in a locking manner. The fixing member 330 has a sliding slot 332 and a shaft portion 334. The distance between the sliding slot 332 and the front plate 210 is smaller than the distance between the shaft portion 334 and the front plate 210, that is, the sliding slot 332 is substantially at the front plate 210 and the shaft. Between the sections 334. The pushing member 320 is slidably coupled to the sliding slot 332 to allow the fixing member 330 to provide a stable movement mode of the pushing member 320 on the front plate 210 due to the structural limit relationship. Moreover, the handle 340 has a pivot 342 and a pushing portion 344, wherein the pivot 342 of the handle 340 is pivotally connected to the shaft portion 334 of the fixing member 330 to rotate the handle 340 relative to the fixing member 330, and to push The rotation path of the portion 344 passes between the shaft portion 334 and the chassis 200.

It is worth mentioning that the handle 340 further has a grip portion 346 which is located on the opposite sides of the pivot 342 from the pushing portion 344 and is farther away from the sliding slot 332 due to the shaft portion 334 of the fixing member 330. The front panel 210 of the chassis 200 is thus pivotally connected to the handle 340 of the shaft portion 334 in a state in which it is disposed away from the chassis 200. In this way, when the user pulls the handle 340 by a gripping opening 346a of the grip portion 346, the pushing portion 344 and the grip portion 346 are the same due to the relative arrangement of the handle 340 and the chassis 200. Rotation along the shaft portion 334 of the fixture 330 (rotation direction A1 shown). This causes the pushing portion 344 to rotate toward the pushing member 320 and press the pushing member 320 (ie, the free end E2 of the driving clip 310) to move the pushing member 320 relative to the chassis 200 in the direction D1 to reach the release card. The effect of the snap relationship between the fastener 310 and the frame 100.

3 is a partial plan view of the server of FIG. 1 for showing the state when the user pulls the handle 340. Referring to FIG. 1 to FIG. 3, in this embodiment, since the latch structures 300 and 400 are symmetrically disposed on both sides of the chassis 200, and based on the movement manner of the handle 340, when the user wants to release the chassis 200 and When the frame 100 is in the buckle relationship, the openings 346a and 446a of the grip portions 346 and 446 are required to be pulled by the hands, so that the pushing portions 344 and 444 of the handles 340 and 440 have different rotational directions A1 and A2, respectively. Rotating, thereby causing the corresponding pushers 320, 420 to slide in the directions D1, D2 to drive the snap portions 314, 414 of the snaps 310, 410 away from the frame 100. At the same time, the user can continue to hold the handles 340, 440 to pull the unfastened chassis 200 out of the frame 100 along the axis L1 from the frame 100. In other words, in addition to enabling the user to release the snap relationship between the chassis 200 and the rack 100 in an easy and economical manner, the latch structure 300, 400 of the present invention can be used while releasing the buckle relationship. As soon as the chassis 200 is pulled out of the rack 100, the user can easily disassemble the chassis 200 in an ergonomic manner.

In addition, FIG. 4 is a partial enlarged view of the server of FIG. 3 at the handle. Referring to FIG. 3 and FIG. 4 simultaneously, the handle 300 is used as a representative. In the embodiment, the pushing portion 344 has a first pushing surface P1 and a second pushing surface P2 adjacent to each other. The first pushing surface P1 abuts against the pushing member 320 as the pushing portion 344 rotates in the direction A1 to drive the pushing member 320 to move on the front plate 210. More importantly, when the first pushing surface P1 abuts against the pushing member 320, the second pushing surface P2 abuts against the front plate 210 of the chassis 200.

In other words, when the chassis 200 is removed from the rack 100, the user only applies the handle 340, but the handle 340 actually has the corresponding structure with the fixing member 330, the pushing member 320 and the front plate 210. Allowing the user to apply the force evenly to the joint of the member, that is, the joint of the handle 330 and the fixing member 330, the abutment of the first pushing surface P1 and the pushing member 320, and the second pushing surface The abutment of P2 and the front plate 210. This allows the chassis 200 to receive the user's force, and also structurally avoid the possibility of component damage caused by concentration of one location due to the above configuration.

In summary, in the above embodiment of the present invention, by the latch structure disposed on the chassis, the user can be fixed in the rack by interfering with the interference between the latch and the rack, thereby allowing the user to At the same time, the handle is pulled by both hands, and the buckle structure and the frame are unbuckled, and the double effect of the user can easily remove the chassis from the rack.
