[0001] The utility model relates to the technical field of door locks, and in particular to a door panel locking structure for a liquid cooling box battery pack. Background Art

[0002] A battery liquid cooling box is an energy storage device that uses liquid cooling technology to dissipate heat. Liquid cooling boxes are usually used to store or cool key components that are sensitive to temperature. There are many considerations for installing a lock on its door:

[0003] Prevent accidental opening; the liquid cooling box may be subject to vibration, shock or other external forces;

[0004] Improved sealing; if one door lock fails or is damaged, the other door locks can still keep the box closed, which can reduce the risk of accidental opening of the box;

[0005] Improved durability: By spreading the load, multiple latches reduce wear and fatigue on individual latches, thereby extending overall service life.

[0006] Therefore, multiple door locks are often used on the door panels of liquid cooling boxes to ensure the safety, sealing and durability of the flat doors. However, multiple door locks are not convenient to open and close on the one hand, and on the other hand, due to the different distances between different areas of the door panel and the door frame, it is difficult for multiple door locks to achieve the effect of accurately locking the door at the same time. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-6 , the utility model provides a technical solution: a door panel locking structure for a liquid cooling box battery pack, comprising a door lock assembly 2, a plurality of transmission assemblies 3 and a plurality of bent baffles 1 matching the transmission assemblies 3;

[0035] Among them, the door lock assembly 2 is used to rotate after inserting an appropriate key, and drive the transmission assembly 3 closest to the door lock assembly 2 to move, so that the transmission assembly 3 abuts against the side wall of the bending baffle 1, thereby locking the flat door. At the same time, multiple transmission assemblies 3 produce the same movement effect through the continuous rod 33, so that multiple transmission assemblies 3 are respectively abutted and locked with multiple bending baffles 1 at the same time.

[0036] The door lock assembly 2 is rotatably connected with a rotating lock shaft 21, and a deflection rack 22 is provided on a side of the rotating lock shaft 21 close to the transmission assembly 3;

[0037] The transmission assembly 3 includes a vertical connecting rod 31 that can slide vertically and a rotatable rotating sleeve 32. A blocking ball 322 that cooperates with the bending baffle 1 is installed on the rotating sleeve 32. A double-sided rack 311 is arranged on the side wall of the vertical connecting rod 31. A gear shaft 321 that cooperates with the double-sided rack 311 for transmission is arranged in the rotating sleeve 32. The double-sided rack 311 is in transmission connection with the deflection rack 22.

[0038] After a suitable key is inserted into the keyhole disposed on the outer side of the door panel 5 in the door lock assembly 2, the key can be used to drive the rotary lock shaft 21 to rotate, so that the rotary lock shaft 21 drives the vertical connecting rod 31 to slide in the vertical direction through the deflection rack 22;

[0039] When the vertical link 31 slides in the vertical direction, the gear shaft 321 is driven to rotate, thereby driving the oblique link 324 and the blocking ball 322 to rotate around the central axis of the gear shaft 321, so that the blocking ball 322 abuts against the side wall of the bent baffle 1 to form a complete door lock mechanism.

[0040] Specifically, Figure 8 As shown, multiple transmission components 3 are evenly spaced along the vertical direction, and a continuous rod 33 is connected between the vertical connecting rods 31 on any two adjacent transmission components 3; multiple bending baffles 1 are respectively arranged in a one-to-one correspondence with the blocking balls 322 on the multiple transmission components 3, wherein the two ends of the multiple continuous rods 33 are respectively connected to the two ends of the two vertical connecting rods 31, so that the vertical connecting rods 31 of the multiple transmission components 3 all produce the same movement, thereby making the blocking balls 322 in the multiple transmission components 3 rotate synchronously and simultaneously abut against the multiple bending baffles 1 accordingly.

[0041] Specifically, Figure 4 As shown, one side of the double-sided rack 311 is meshed with the gear shaft 321, and the other side is meshed with the deflection rack 22; a side of the blocking ball 322 close to the rotating sleeve 32 is provided with an oblique connecting rod 324, the oblique connecting rod 324 abuts against the rotating sleeve 32, and a stud 323 is screwed and connected at the abutment, and the nut end of the stud 323 abuts and fixes against the oblique connecting rod 324;

[0042] The racks on both sides of the double-sided rack 311 are used to synchronously drive the rotation of the rotating lock shaft 21 and the rotation of the rotating sleeve 32, and the continuous rod 33 connected between the multiple vertical connecting rods 31 makes the multiple rotating sleeves 32 produce the same rotation, so that the multiple oblique connecting rods 324 drive the corresponding blocking balls 322 to abut against the corresponding bent baffles 1, so as to achieve the effect of locking and unlocking at multiple locations at the same time;

[0043] At the same time, the stud 323 is provided to connect and fix the oblique connecting rod 324 and the rotating sleeve 32 to each other, and the installation angle of the oblique connecting rod 324 and the rotating sleeve 32 can be adjusted to adapt to different distances between the door panel 5 and the door frame 4.
