Since the position of the wrench shaft 211 remains unchanged, the second push-pull rod 23 moves relative to the guide rail 3, which can drive the wrench 21 to rotate, thereby facilitating the realization of the linkage effect.

[0067] Specifically, in a specific embodiment, the plug-in card base 1 and the wrench assembly 2 are pre-assembled parts; when the plug-in card 100 needs to be installed, the plug-in card base 1 and the partial structure of the wrench assembly 2 are first pushed into the guide rail 3, and at this time, the wrench 21 contacts the rear end of the long inclined groove, such as Figure 3The first push-pull rod 22 is then pulled to move in the direction of pulling out, and the first push-pull rod 22 pulls the second push-pull rod 23 to move in the direction of pulling out, until the wrench 21 contacts the front end of the long inclined groove, and the locking front jaws 241 are lifted up, no longer abutting against the guide rail rear end surface 326, but flush with the support surface 321 of the guide rail 3.

Since the supporting surface 321 and the rear jaws avoidance groove 322 limit the wrench 21, the wrench 21 will not rotate, and the relative position of the second push-pull rod 23 and the wrench 21 remains unchanged. The first push-pull rod 22 is continuously pushed until the locked rear jaws 242 of the wrench 21 moves to the end surface of the rear jaws avoidance groove 322 away from the rear end surface 326 of the guide rail, that is, the front end of the rear jaws avoidance groove 322. The front locking jaws 241 of the locking mechanism 242 are in the same position as the inner card slot, and the support surface 321 no longer limits the front locking jaws 241. As the first push-pull rod 22 continues to advance, the second push-pull rod 23 is no longer restricted and will be pushed in the direction of pulling in together with the first push-pull rod 22. The front locking jaws 241 will gradually fall into the inner card slot until the second push-pull rod 23 is locked with the inner card lock buckle 12. At this time, the front locking jaws 241 of the locking mechanism 242 are in the same position as the inner card slot, and the rear locking jaws 242 are in the same position as the inner card slot. 00 is pulled out of the slot and cooperates with the limit to complete the installation process of the plug-in card 100; when the plug-in card 100 needs to be removed, the first push-pull rod 22 is pulled in the opposite direction, and the first push-pull rod 22 first unlocks the plug-in card lock 12, and then drives the second push-pull rod 23 to move. When the second push-pull rod 23 moves to the front end of the long oblique slot and cooperates with the wrench 21, the front locking jaws 241 are lifted up again and disengaged from the plug-in card slot. Continue to pull the first push-pull rod 22, and the plug-in card base 1 can be pulled out, and the removal process of the plug-in card 100 is completed.

[0076] In some embodiments, please refer to Fig. 9 The folding arm assembly 4 includes an outer folding arm 41, which is hinged to the first push-pull rod 22. The outer folding arm 41 can be unfolded to an extension direction parallel to the guide rail 3, or folded to an extension direction perpendicular to the guide rail 3. The outer folding arm 41 is also provided with a folding arm lock 411 for locking or unlocking with the guide rail 3; by providing the folding arm lock 411 on the outer folding arm 41, the stability of the plug-in card 100 can be further guaranteed. When the plug-in card 100 needs to be removed, it is necessary to manually unlock the folding arm lock 411 first, and then unlock the second push-pull rod 23 through the first push-pull rod 22. With this arrangement, the locking and unlocking process of the second push-pull rod 23 can be transferred to the outer folding arm 41, and there is no need to extend into the chassis 300 for operation, which effectively improves efficiency and realizes the operation mode of installing the plug-in card 100 inside the chassis 300, saving space in the chassis 300 and facilitating layout.

[0077] In some embodiments, please refer to Fig.10 and Fig.11 The folding arm assembly 4 also includes an inner folding arm 43, which is hinged to the first push-pull rod 22, and the inner folding arm 43 is hinged to the outer folding arm 41.

Of course, the unlocking portion can also be partially extended to the outside of the unlocking slot, and unlocked with the help of other tools to avoid the risk of accidental touch; further, in order to achieve automatic locking of the folding arm lock 411, the folding arm lock 411 also includes an elastic component of the folding arm lock 411, such as a torsion spring. When the outer end folding arm 41 moves to the target position, the folding arm lock 411 and the folding arm locking portion 327 are automatically locked, and the operation is convenient.

[0079] In some embodiments, please refer to Figures 12 to 15 The guide rail 3 includes an upper guide rail 31 and a lower guide rail 32, the internal card base 1 is installed between the upper guide rail 31 and the lower guide rail 32, the internal card pull-in surface 323 and the internal card pull-out surface 324 are arranged on the surface of the lower guide rail 32; an avoidance groove is provided at the bottom of the limit member 11, and the locking jaws 24 can penetrate the avoidance groove and then cooperate with the lower guide rail 32. Specifically, the left and right sides of the inner wall of the chassis 300 are provided with an upper guide rail 31 and a lower guide rail 32 that cooperate with the internal card base 1. The length of the upper guide rail 31 is roughly the sum of the depths of the external card 200 + the internal card 100; the upper limit surface of the internal card base 1 and the left limit surface or the right limit surface of the folding wall assembly are designed below the upper guide rail 31; the length of the lower guide rail 32 is roughly the total length of the external card base + the internal card base 1; the upper surface of the lower guide rail 32 is a complete plane, which is the support surface 321 of the internal card base 1 and the external card base, and also provides a support surface for the external card base and the internal card base 1 The lower guide rail 32 is a sliding surface for plugging and unplugging back and forth in the chassis 300; the side surface of the lower guide rail 32 is a guiding plane of the external card base, which is also the left and right limit plane of the external card base; the lower guide rail 32 is provided with an external card 200 pull-in slot of the external card base, and the external card 200 pull-in slot is provided with an external card pull-in surface 325, and the lower guide rail 32 is also provided with an external card 200 pull-out slot of the external card base, and the external card 200 pull-out slot is provided with an external card pull-out surface; the lower guide rail 32 is also provided with a folding arm locking portion 327, an internal card pull-in slot and an internal card pull-in surface 323, and a rear tiger's mouth avoidance groove 322 is also opened on the lower guide rail 32.

[0080] In some embodiments, the upper surface of the upper guide rail 31 has the same structure as the upper surface of the lower guide rail 32, the lower surface of the lower guide rail 32 has the same structure as the lower surface of the upper guide rail 31, and the upper guide rail 31 and the lower guide rail 32 are both symmetrically distributed left and right in the chassis 300 to form a multi-layer structure in the chassis 300.

[0081] The card module can extend the operating length of the wrench 21 when unfolded and reduce the volume of the card module when folded, which is convenient for carrying and transporting the card module. The outer push-pull rod is set to integrate the unlocking of the inner card lock buckle 12, so that the whole operation is seamless and can be smoothly plugged and unplugged without the need for additional operation by the user. The wrench 21 with a large leverage ratio can solve the problem of pulling in and out the inner card base 1 itself, and can also cooperate with the inner card lock buckle 12 inside it to keep the position after the inner card base 1 is installed in place. The position remains unchanged and will not be pulled out by the external card 200; the internal card base 1 and the wrench assembly 2 are maintained by a pull-out method, so that when the internal card base 1 is in a deeper position in the chassis 300, it can be conveniently plugged and unplugged for maintenance, and the plugging and unplugging are smooth and natural, which conforms to ergonomics; the folding arm lock 411 that can be pinched and unlocked and is arranged on the inner side of the outer end folding arm 41 can solve the operation of accidentally pulling out the internal card 100 when the external card 200 is installed in place, and makes the unlocking and pulling out operation of the internal card 100 more convenient and natural when the external card 200 is not in place.

[0082] Specifically, in a specific embodiment, please refer to Figures 16 to 22 When the insert card 100 needs to be pulled in, that is, when the insert card 100 moves in the pulling direction, the pulling direction is as follows: Fig.16 As shown by the arrow in the middle, first, the folding arm assembly 4 is in a folded state, at which time a part of the structure of the inner card base 1 can be inserted into the chassis 300, as shown in FIG. Fig.16 , until the locking front jaw 241 of the wrench 21 is blocked by the rear end surface 326 of the guide rail of the lower guide rail 32 in the chassis 300, and then stops. Fig.17 At this time, the folding arm assembly 4 can be unfolded and pulled out to the bottom, such as Fig.18 At this time, the inner card lock buckle 12 will be unlocked by the first push-pull rod 22. Figure 7As shown, and under the action of the inner card unlocking portion 221, the unlocking state is always maintained. After the first push-pull rod 22 is pulled out to the bottom, that is, when the rear side of the long inclined groove of the second push-pull rod 23 contacts the wrench shaft 211, the first push-pull rod 22 is pulled out to the outermost position, and then the inner card front panel 13 is pushed, so that the locking front jaws 241 contact the supporting surface 321 of the lower guide rail 32; when the entrance space of the chassis 300 is small and the inner card front panel 13 cannot be pushed inward manually, the outer end folding arm 41 in the folding arm assembly 4 can be pushed at this time. It can be seen that at this time, the locking front jaws 241 contact the supporting surface 321 of the lower guide rail 32, and the locking rear jaws 242 just enter the rear jaws avoidance groove 322, as shown in FIG. Fig.19 and Fig. 20 As shown, in the process of continuing to push the outer folding arm 41, the locking front jaw 241 will always be against the supporting surface 321 of the lower guide rail 32, so that the lever of the wrench 21 will not rotate in advance, and the outer folding arm 41 can be pushed inward all the time without pushing the second push-pull rod 23 in advance. This is why the locking front jaw 241 and the locking rear jaw 242 are designed to be staggered, and each folding arm in the folding arm assembly 4 will sequentially enter the recessed grooves of the upper guide rail 31 and the lower guide rail 32 of the chassis 300, pushing the internal card base 1 into the deep of the chassis 300;

[0083] When the locking rear jaw 242 contacts the end surface of the rear jaw avoiding groove 322 away from the rear end surface 326 of the guide rail, that is, when the locking rear jaw 242 contacts the inner card pull-out surface 324, as shown in FIG. Fig.21 As shown, if the outer folding arm 41 is pushed continuously, the first push-pull rod 22 will drive the second push-pull rod 23 to move. At this time, the wrench 21 rotates, and its locking front jaws 241 will contact the inner card insertion surface 323 of the lower guide rail 32. The outer folding arm 41 is pushed continuously, and the inner card base 1 begins to be pulled into the chassis 300 under the lever force of the wrench 21. Fig. 22 Continue to push the end face of the outer folding arm 41 until the folding arm lock 411 is locked into the lower guide rail 32 of the chassis 300; at this time, the inner card lock 12 will also rebound and lock the second push-pull rod 23, so that when the outer card 200 is pulled out, the inner card 100 will not be brought out due to the friction of the connector.

[0084] When the internal card 100 needs to be pulled out, the reverse operation of the above-mentioned pulling-in process can be referred to; pinch the unlocking part on the outer folding arm 41 and unlock it, the outer folding arm 41 can be pulled outward, and the outer folding arm 41 pulls the first push-pull rod 22 outward, thereby unlocking the second push-pull rod 23 and the internal card lock 12, and then the first push-pull rod 22 can pull the second push-pull rod 23, and the wrench 21 rotates, thereby pulling the internal card 100 out of the chassis 300. For pulling in and pulling out the external card 200, the external card pulling-in surface 325 and the external card pulling-out surface set on the lower guide rail 32 are used to operate through the external wrench component 5.

[0085] The card module solves the problem of plugging and unplugging maintenance of the internal card 100 when there is an internal card 100 in the chassis 300; by designing the folding arm assembly 4 and the wrench assembly 2, the external card 200 that originally must be maintained from the front and rear panels of the chassis 300 can be placed inside the chassis 300 for maintenance, so that the card module does not need to occupy the panel space, thereby improving the panel space utilization of the chassis 300; the wrenches 21 used for the internal card 100 and the external card 200 have their own independent pulling positions, and their maintenance does not affect each other.

[0086] In the present application, the end actuator for pulling the inner card 100 in and out is arranged on the card body, so as to avoid the problem that the bus backplane connector cannot be pulled into place and cannot be plugged in tightly due to too many parts of the folding arm assembly 4 and the wrench assembly 2 and too large tolerance of the dimensional chain length. The extended folding arm assembly 4 and the wrench assembly 2 indirectly transmit the push and pull force applied by the hand to the wrench 21; by arranging the inner card lock buckle 12 in the sliding cavity, when the wrench 21 is pulled into place, the inner card base 1 can be locked, thereby avoiding the problem that the inner card 100 may be pulled out due to the friction of the connector when the external card 200 is pulled out; By setting the first push-pull rod 22, the first push-pull rod 22 integrates the function of indirectly pushing and pulling the internal end wrench 21 mechanism, and also has the function of remotely locking and unlocking the wrench 21 lock; by designing the locking jaws 24 to be staggered in the form of the front locking jaws 241 and the rear locking jaws 242, and then cooperating with the rear jaws avoidance groove 322 and the support surface 321 structure of the guide rail 3, the problem of preventing the pull rod from rotating prematurely when pushing the outer end folding arm 41 is solved, so that when the front panel 13 of the plug-in card cannot be pushed by hand, pushing the outer end folding arm 41 can also push the plug-in card base 1 into the deep of the chassis 300.

[0087] In addition to the above-mentioned card module, the present invention further provides a storage device including the above-mentioned card module. For the structure of other parts of the storage device, please refer to the relevant technology and will not be described in detail herein.
