[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a PACK module mechanical anti-theft cabinet, comprising a cabinet body, a lock body connecting frame, a lock bracket, an electromagnetic latch and a plurality of trays, wherein the cabinet body is open only at the front and is hinged with a cabinet door, the plurality of trays are fixed in the cabinet body at equal intervals along the vertical direction, and a cavity for inserting and storing the PACK module is formed between each two adjacent trays, the lock body connecting frame is fixed to the rear end face of the PACK module, the lock body connecting frame comprises an outer shell and a lock pin, the outer shell body is an H-shaped empty shell with four vertices open and a fifth lock point through groove is integrally extended downward at the middle position of its horizontal arm, the lock pin comprises a middle latch rod received in the fifth lock point through groove and two edge latch rods received in the two vertical arms of the outer shell, the middle latch rod is fixed to the rear end face of the PACK module, the lock body connecting frame comprises an outer shell and a lock pin, the outer shell body is an H-shaped empty shell with four vertices open and a fifth lock point through groove is integrally extended downward at the middle position of its horizontal arm, the lock pin comprises a middle latch rod received in the fifth lock point through groove and two edge latch rods received in the two vertical arms of the outer shell, The intermediate latch rod and the two edge latch rods are connected as a whole through a connecting beam. Two springs are arranged inside the horizontal arm of the shell to support the two sides of the bottom of the connecting beam so that the locking pin can be elastically retracted into the shell. The rear end of the tray corresponding to the bottom of the PACK module is fixed with a lock bracket. The lock bracket is located directly below the lock body connecting frame and is correspondingly provided with three keyhole grooves. Two electromagnetic latches are fixed to the rear end of the tray corresponding to the top of the PACK module. The two electromagnetic latches are normally closed when power is off, and in the power-off state, the plugs of the two electromagnetic latches are respectively extended and inserted into the top ends of the two vertical arms of the shell. At the same time, the plugs of the two electromagnetic latches push the locking pin downward to insert the intermediate latch rod and the two edge latch rods into the three keyhole grooves. The PACK module is controlled by the BMS arranged inside to provide unlocking signals for the two electromagnetic latches.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention fixes the lock body connecting frame on the rear end face of the PACK module, and its appearance structure is simple and ingenious. A lock pin is elastically retracted inside the shell. When the PACK module is inserted and stored between two adjacent trays in the cabinet, the plugs of the two electromagnetic locks are extended and inserted into the top ends of the two vertical arms of the shell in the power-off state to complete two-point locking, and the lock pin is pushed downward by the electromagnetic lock and inserted into the three keyhole grooves of the lock bracket to complete three-point locking. There are a total of five stable and reliable lock points. In addition to connecting the BMS with a computer device or a mobile phone device with a control instruction to power the electromagnetic lock and unlock it, the PACK module can only be removed by mechanical cutting and violent destruction. It is easy to install on the basis of the existing cabinet for retracting and releasing the PACK module, has strong anti-theft performance, and reduces loss costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0014] like Figure 1 to Figure 6 As shown, a PACK module mechanical anti-theft cabinet includes a cabinet body 1, a lock body connecting frame 4, a lock bracket 5, an electromagnetic latch 6 and a plurality of trays 2.

[0015] Combination Figure 1-2As shown, the cabinet 1 is only open at the front and is hinged with a cabinet door 1-1, and the multiple trays 2 are fixed in the cabinet 1 at equal intervals along the vertical direction, and a chamber for inserting and storing the PACK module 3 is formed between each two adjacent trays 2, wherein the movable end of the cabinet door 1-1 is preferably equipped with a lock 1-2 that can be locked and connected with the cabinet 1, which plays a preliminary and simple anti-theft effect. In addition, the cabinet 1 and the cabinet door 1-1 can be respectively provided with heat dissipation holes 1-3 to facilitate ventilation and heat dissipation of the internal PACK module 3, and handles 3-1 can be respectively provided on both sides of the front end surface of the PACK module 3 to facilitate the insertion and pulling out of the PACK module 3.

[0016] Combination Figure 3 to Figure 6 As shown, the rear end face of the PACK module 3 is fixed with a lock body connecting frame 4, and the lock body connecting frame 4 includes a shell 41 and a lock pin 42. The main body of the shell 41 is an H-shaped hollow shell with four open vertices, and the middle position of its horizontal arm also extends downward with a fifth lock point through groove 411. The lock pin 42 includes a middle latch rod 422 received in the fifth lock point through groove 411 and two edge latch rods 421 received in two vertical arms of the shell 41. The middle latch rod 422 and the two edge latch rods 421 are connected as a whole through a connecting beam 423. Two springs 43 are arranged inside the horizontal arm of the shell 41 to support the connecting beam. The two sides of the bottom of the beam 423 allow the lock pin 42 to be elastically retracted in the shell 41. The rear end of the tray 2 corresponding to the bottom of the PACK module 3 is fixed with a lock bracket 5, and the lock bracket 5 is located directly below the lock body connecting frame 4 and is correspondingly provided with three keyhole grooves 5-1. Two electromagnetic latches 6 are fixed to the rear end of the tray 2 corresponding to the top of the PACK module 3. The two electromagnetic latches 6 are of the normally closed type when the power is off, and in the power-off state, the plugs of the two electromagnetic latches 6 are respectively extended and inserted into the top ends of the two vertical arms of the shell 41. At the same time, the plugs of the two electromagnetic latches 6 push the lock pin 42 downward to insert the middle latch rod 422 and the two edge latch rods 421 into the three keyhole grooves 5-1. Specifically, the electromagnetic latch 6 is a prior art, and its principle is that the compression spring arranged inside supports the plug to extend in the power-off state, and the electromagnet arranged inside generates a magnetic force to overcome the elastic force of the compression spring and magnetically retract the plug to achieve unlocking in the power-on state. In order to facilitate the insertion of the PACK module 3 between the two trays 2, the plugs of the two electromagnetic latches 6 are inserted into the top ends of the two vertical arms of the shell 41, and the plug ends of the electromagnetic latches 6 can be processed with guide slopes. In order to achieve the plugs of the two electromagnetic latches 6 pushing the lock pin 42 downward, it is naturally required that the stiffness coefficient of the compression spring arranged inside the electromagnetic latch 6 is greater than the stiffness coefficient of the spring 43 in the lock body connecting frame 4.

[0017] Combination Figure 7As shown, the PACK module 3 is controlled by the internally arranged BMS to provide unlocking signals for the two electromagnetic locks 6. A BMS interface is reserved on the PACK module 3, wherein the connecting wires of the two electromagnetic locks 6 are connected to the PACK module 3 by quick plug connection, and the unlocking of the electromagnetic locks 6 is achieved by the BMS controlling the PACK module 3 to supply power to the electromagnetic locks 6. Preferably, the BMS provides instructions through an external computer device or mobile phone device, and then controls the PACK module 3 to supply power to the two electromagnetic locks 6 to achieve unlocking, so that only the computer device or mobile phone device with the instruction can control the BMS, thereby finally achieving efficient security and anti-theft effect.
