A chassis based on a quick-disassembly LRM module

Abstract

The present invention relates to the technical field of server chassis, and particularly relates to a chassis based on a quick-detachable LRM module; when an LRM module needs to be installed, the connection plug is inserted into the connection socket in a matching manner; then the rotating cap is pushed inward so that the locking head approaches the first fixing pin, and the first fixing pin passes through the horizontal groove. When the rotating cap cannot be pushed inward any further, the rotating cap is rotated to drive the connecting rod and the locking head to rotate; thereby enabling the first fixing pin to be embedded in the vertical through hole, and further fixing the axial position of the locking head. At this time, the rotating cap abuts against the first edge plate, so that the LRM module is fixed to the chassis main body through the first fixing pin; when the LRM module needs to be disassembled, the rotating cap is rotated in the reverse direction, so that the first fixing pin is disengaged from the vertical through hole and returns to the horizontal groove. At this time, the rotating cap can be pulled outward, so that the locking head is pulled out through the connecting rod, and the locking head and the first fixing pin are disengaged, and the LRM module is no longer fixed to the chassis main body.

[0041] At the same time, as shown in the attached Figure 7As shown, one end of the second edge plate 350 away from the base plate 380 is recessed to form a third cavity 370; a second fixing pin 460 is arranged in the third cavity 370; the first fixing pin 450 and the second fixing pin 460 have the same diameter, and the first fixing pin 450 and the second fixing pin 460 share the same central axis; a second protruding plate 320 is arranged on one side of the LRM module 120 away from the connection plug 280; the second protruding plate 320 is also provided with one rotation locking member 330; the second fixing pin 460 can be sequentially inserted into the horizontal groove 530 and the vertical through hole 540 of the rotation locking member 330 arranged on the second protruding plate 320; when the rotation locking member 330 rotates to the second fixing pin 460 being inserted into the vertical through hole 540, the rotation cap 470 abuts against the second edge plate 350, so that the LRM module 120 is fixed to the chassis main body 110. By providing the second rotation locking member 330, the connection stability between the LRM module 120 and the chassis main body 110 can be enhanced.

With such a setting, the position between the LRM module 120 and the chassis main body 110 can be made more accurate, thereby improving the stability when the LRM module 120 is connected and installed on the chassis main body 110.

[0048] Specifically, the LRM module 120 further includes a fifth plate wall 240; the first plate wall 130 and the second plate wall 140 are both perpendicular to the fifth plate wall 240; the connection plug 280 is arranged on the fifth plate wall 240; the fifth plate wall 240 is further provided with a loop-shaped conductive pad 270; the connection plug 280 is located within the loop-shaped conductive pad 270; when the connection plug 280 is fitted and embedded into the connection socket 290, the loop-shaped conductive pad 270 abuts against the base plate 380. Through the above technical solution, when the connection plug 280 is fitted and embedded into the connection socket 290, the loop-shaped conductive pad 270 abuts against the base plate 380, thereby preventing the connection plug 280 and the connection socket 290 from being exposed when they are fitted and plugged, and playing a role in sealing and electromagnetic shielding.

[0049] In addition, the first plate wall 130 is further provided with a handle 560 and heat dissipation fins 180; the fifth plate wall 240 is further provided with a first positioning hole 250 and a second positioning hole 260; the first positioning hole 250 and the second positioning hole 260 are respectively on both sides of the loop-shaped conductive pad 270; the base plate 380 is connected with a first positioning pin 410 and a second positioning pin 420; the first positioning pin 410 is parallel to the second positioning pin 420; the central axes of the first positioning hole 250 and the second positioning hole 260 are parallel to each other; the first positioning pin 410 is used for fitting and embedding into the first positioning hole 250; the second positioning pin 420 is used for fitting and embedding into the second positioning hole 260. By providing positioning holes and positioning pins, the position accuracy between the LRM module 120 and the chassis main body 110 is further improved, thereby improving the stability when the LRM module 120 is connected and installed on the chassis main body 110.

[0050] At the same time, as shown in the attached Figure 4 and attached Figure 8As shown in the figure, the chassis based on the quick-detachable LRM module further includes a heat transfer component; the heat transfer component includes a first heat conduction strip 580, a second heat conduction strip 590, a cable 610, a heat conduction plate 640, a second spring 630, and a wedge plate 650; the first heat conduction strip 580 is connected to the heat conduction plate 640; the number of the first heat conduction strips 580 is multiple; each of the first heat conduction strips 580 is parallel to each other and arranged at equal intervals; the second heat conduction strip 590 is connected to the side plate 570; the number of the second heat conduction strips 590 is multiple; each of the second heat conduction strips 590 is parallel to each other and arranged at equal intervals; the number of the second heat conduction strips 590 is 1 more than the number of the first heat conduction strips 580; one first heat conduction strip 580 is arranged between every two adjacent second heat conduction strips 590; the side wall of the first heat conduction strip 580 is in sliding fit contact with the side wall of the second heat conduction strip 590; the cable 610 is a flexible cable 610; the number of the cables 610 is the same as the number of the first heat conduction strips 580; the cables 610 and the first heat conduction strips 580 are in one-to-one correspondence; one end of the cable 610 is connected to the corresponding first heat conduction strip 580, and the other end of the cable 610 is connected to the side plate 570, and the cable 610 is between two adjacent second heat conduction strips 590; the number of the second springs 630 is multiple; one end of the second spring 630 is connected to the heat conduction plate 640, and the other end of the second spring 630 is connected to the side plate 570; the second spring 630 is always in a compressed state; the elastic force of the second spring 630 makes the heat conduction plate 640 tend to be away from the side plate 570 and makes the cable 610 stretched; the heat conduction plate 640 is parallel to the side plate 570; a wedge plate 650 (for facilitating the installation of the LRM module 120) is connected to the side of the heat conduction plate 640 away from the base plate 380; the heat conduction plate 640 is used for fitting and abutting against the second plate wall 140.

[0051] Through the above technical solution, when the LRM module 120 is installed on the chassis main body 110, the heat conduction plate 640 fits and abuts against the second plate wall 140; the heat generated when the chassis main body 110 works can be transferred to the first heat conduction strip 580 through the second heat conduction strip 590, and then transferred to the LRM module 120 through the heat conduction plate 640, and then dissipated by the fan 170 of the LRM module 120, that is, the chassis main body 110 can dissipate heat by means of the heat dissipation structure of the LRM module 120, further reducing the working temperature of the chassis main body 110, thereby ensuring the overall stability when the chassis main body 110 and the LRM module 120 work.
