[0030] At the same time, if attached Figure 7As shown, one end of the second edge plate 350 away from the base plate 380 is concave to form a third cavity 370; a second fixing pin 460 is arranged in the third cavity 370; the diameters of the first fixing pin 450 and the second fixing pin 460 are consistent, and the first fixing pin 450 and the second fixing pin 460 share a central axis; a second protruding plate 320 is arranged on the side of the LRM module 120 away from the connecting plug 280; the second protruding plate 320 is also provided with a rotation locking member 330; the second fixing pin 460 can be sequentially embedded in the transverse 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 until the second fixing pin 460 is embedded in the vertical through hole 540, the rotating cap 470 abuts against the second edge plate 350, so that the LRM module 120 is fixed to the chassis body 110. By providing the second rotation locking member 330 , the connection stability between the LRM module 120 and the chassis body 110 can be enhanced.

[0031] In addition, if attached Figure 5 and attached Figure 6 As shown, the rotary locking member 330 also includes a sleeve 550 and a retaining ring 480; the retaining ring 480 is connected to one end of the rotary cap 470 close to the locking head 520; the sleeve 550 is connected to one end of the locking head 520 close to the retaining ring 480; the outer diameter of the sleeve 550 is consistent with the outer diameter of the locking head 520; the inner diameter of the retaining ring 480 is larger than the inner diameter of the sleeve 550; the retaining ring 480 and the sleeve 550 share a central axis; the connecting rod 490 and the first spring 510 are both in the sleeve 550; the connecting rod 490 and the locking head 520 are coaxially fixedly connected; the connecting rod 490 and the rotary cap 470 are connected by a sliding key (not shown) The connecting rod 490 is connected so that when the rotating cap 470 rotates, it can drive the connecting rod 490 to rotate, and the rotating cap 470 can slide axially relative to the connecting rod 490; the sleeve 550 of the rotating locking member 330 provided on the first protruding plate 310 is movably passed through the first protruding plate 310; the retaining ring 480 of the rotating locking member 330 provided on the first protruding plate 310 is used to abut the first protruding plate 310; the sleeve 550 of the rotating locking member 330 provided on the second protruding plate 320 is movably passed through the second protruding plate 320; the retaining ring 480 of the rotating locking member 330 provided on the second protruding plate 320 is used to abut the second protruding plate 320.

[0032] Specifically, the first protruding plate 310 is provided with a first through hole; the sleeve 550 is movably provided in the first through hole; the second protruding plate 320 is provided with a second through hole; the sleeve 550 is movably provided in the second through hole.

[0033] The above technical solution improves the specific structure and function of the rotary locking member 330; taking the rotary locking member 330 arranged on the first protruding plate 310 as an example, the sleeve 550 is movably penetrated into the first through hole, and the connecting rod 490 and the locking head 520 can be driven to move axially by pushing or pulling the rotary cap 470, and the locking head 520 can be driven to rotate by rotating the rotary cap 470; when the entire rotary locking member 330 is rotated until the first fixing pin 450 is embedded in the vertical through hole 540, the retaining ring 480 abuts against the first protruding plate 310, and under the pulling force of the first spring 510, the entire LRM module 120 is squeezed in the direction close to the connecting socket 290, so that the connecting plug 280 can be more firmly embedded in the connecting socket 290, and the connection between the LRM module 120 and the chassis body 110 can also be made more stable.

[0034] In addition, the LRM module 120 includes a first plate wall 130 and a second plate wall 140 which are parallel to each other; the first plate wall 130 is located on a side away from the chassis body 110; the first plate wall 130 is provided with a fan 170 and a fixed cover 150 for covering the fan 170; the fixed cover 150 is provided with a plurality of ventilation holes 160; the first plate wall 130 is provided with a fan interface (not shown); the fan 170 is electrically connected to the fan interface; the fan interface is a J30J connector.

In addition, the fan 170 and the fixed cover 150 are all detachably connected to the first plate wall 130; under appropriate conditions, the fan 170 and the fixed cover 150 can also be removed to reduce the overall thickness of the LRM module 120, thereby meeting the needs of various actual use places. In this embodiment, the thickness of the fan 170 is selected to be 25 mm, and the overall thickness of the fan 170 and the fixed cover 150 is 29 mm.

[0036] At the same time, if attached Figure 2 and attached Figure 3As shown, a first guide arm 430 is provided on a side of the first edge plate 340 facing the second edge plate 350; a second guide arm 440 is provided on a side of the second edge plate 350 facing the first edge plate 340; the first guide arm 430 and the second guide arm 440 are parallel to and directly opposite to each other; the LRM module 120 also includes a third plate wall 190 and a fourth plate wall 210 parallel to each other; the third plate wall 190 is provided with a first groove 220; the fourth plate wall 210 is provided with a second groove 230; the first guide arm 430 is used to slide into the first groove 220, and the outer wall of the first guide arm 430 is in sliding contact with the inner wall of the first groove 220; the second guide arm 440 is used to slide into the second groove 230, and the outer wall of the second guide arm 440 is in sliding contact with the inner wall of the second groove 230. Such an arrangement can make the position between the LRM module 120 and the chassis body 110 more accurate, thereby improving the stability of the LRM module 120 when connected and installed on the chassis body 110.

Through the above technical solution, when the connection plug 280 is fitted and embedded in the connection socket 290, the circular 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 of sealing and electromagnetic shielding.

[0038] In addition, the first plate wall 130 is also provided with a handle 560 and a heat sink fin 180; the fifth plate wall 240 is also 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 located on both sides of the circular 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 to fit in the first positioning hole 250; the second positioning pin 420 is used to fit in the second positioning hole 260. By providing positioning holes and positioning pins, the position accuracy between the LRM module 120 and the chassis body 110 is further improved, thereby improving the stability of the LRM module 120 when connected and installed on the chassis body 110.

[0039] At the same time, if attached Figure 4 and attached Figure 8As shown, the chassis based on the quick-detachable LRM module also includes a heat transfer component; the heat transfer component includes a first heat-conducting bar 580, a second heat-conducting bar 590, a cable 610, a heat-conducting plate 640, a second spring 630 and a wedge plate 650; the first heat-conducting bar 580 is connected to the heat-conducting plate 640; the number of the first heat-conducting bars 580 is multiple; each first heat-conducting bar 580 is parallel to each other and arranged at equal intervals; the second heat-conducting bar 590 is connected to the side plate 570; the number of the second heat-conducting bars 590 is multiple; each second heat-conducting bar 590 is parallel to each other and arranged at equal intervals; the number of the second heat-conducting bars 590 is one more than the number of the first heat-conducting bars 580; one first heat-conducting bar 580 is arranged between every two adjacent second heat-conducting bars 590; the side wall of the first heat-conducting bar 580 is in sliding contact with the side wall of the second heat-conducting bar 590; the cable 610 is a flexible cable 610; the cable 61 0 is consistent with the number of first thermally conductive strips 580; the cable 610 corresponds to the first thermally conductive strip 580 one by one; one end of the cable 610 is connected to the corresponding first thermally conductive strip 580, and the other end of the cable 610 is connected to the side plate 570, and the cable 610 is located between two adjacent second thermally conductive strips 590; the number of second springs 630 is multiple; one end of the second spring 630 is connected to the thermally conductive 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 thermally conductive plate 640 tend to move away from the side plate 570 and makes the cable 610 straight; the thermally conductive plate 640 is parallel to the side plate 570; a wedge plate 650 is connected to the side of the thermally conductive plate 640 away from the base plate 380 (to facilitate the installation of the LRM module 120); the thermally conductive plate 640 is used to fit against the second plate wall 140.

[0040] Through the above technical solution, when the LRM module 120 is installed on the chassis body 110, the heat conducting plate 640 is in contact with the second plate wall 140; the heat generated by the chassis body 110 during operation can be transferred to the first heat conducting bar 580 through the second heat conducting bar 590, and then transferred to the LRM module 120 through the heat conducting plate 640, and then dissipated through the fan 170 of the LRM module 120, that is, the chassis body 110 can dissipate heat with the help of the heat dissipation structure of the LRM module 120, further reducing the operating temperature of the chassis body 110, thereby ensuring the overall stability of the chassis body 110 and the LRM module 120 during operation.
