[0002] Charging refers to the process of replenishing the power of equipment such as batteries. The principle is to let direct current pass in the opposite direction of discharge to restore the active substances in the battery. Now, it has extended meanings such as learning and working. The working process of a battery receiving electrical energy from an external circuit and converting it into chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be discharged again through charging, forming a charge-discharge cycle. It is generally charged with direct current (also useful for asymmetric alternating current or pulse current). Different charging methods are used in different situations, such as constant current charging, constant voltage charging, floating charging, trickle charging, rapid charging or a combination of these methods. In the process of using a mobile cold storage on a vehicle, it is generally directly connected to the vehicle power supply, but there are also some special cases where a specific charging device is required to charge with a lithium battery pack.

[0023] The present invention provides Figure 1-5 A vehicle-mounted charging device dedicated to a mobile cold storage is shown, comprising a storage box 1, a box cover 2 and a lithium battery block 3. The top of the storage box 1 is rotatably connected to the box cover 2 through a spring hinge. Multiple groups of lithium battery blocks 3 are arranged in the storage box 1. Multiple groups of slots arranged at equal intervals are opened in the vertical inner wall of the storage box 1, and the spacing between two adjacent groups of slots is the same as the thickness of the lithium battery block 3. The inner wall of the storage box 1 is bonded with a rubber plate by adhesive. The other two groups of symmetrically arranged vertical side surfaces of the storage box 1 are both provided with shock-absorbing plug-ins 4. Moving devices 5 are installed in the grooves dug in the two groups of symmetrically arranged vertical outer walls of the storage box 1. The two groups of vertical inner walls of the storage box 1 are both provided with locking devices 6, and the shock-absorbing plug-in 4 is arranged below the locking device 6;

[0024] The electrodes of one group of the lithium battery blocks 3 are connected to the electrode wires of the adjacent lithium battery blocks 3 through conductive wires (the wires are not shown), and a protective device 7 is also installed on the top of the lithium battery block 3.

[0025] Specifically, the shock-absorbing plug-in 4 includes a vertical plate 8, a pressure spring 9, a back plate 10 and a foam plate 11. The vertical plate 8 and the back plate 10 are fixedly connected by multiple groups of pressure springs 9 arranged in a rectangular array. The pressure spring 9 provides the main shock-absorbing and buffering effect. The side of the back plate 10 away from the vertical plate 8 is bonded with a foam plate 11 for shock absorption by adhesive. The foam plate 11 not only has an auxiliary shock-absorbing effect, but also protects the side of the lithium battery block 3.

[0026] Specifically, the protection device 7 includes a protection cover 12 and a pull rod 13. The protection cover 12 is configured as a hollow tube with a closed structure at the top. The top of the lithium battery 3 is provided with an annular channel for inserting the protection cover 12. The side of the protection cover 12 is also provided with a channel for the power line to pass through. A connecting ear is fixedly welded to the top of the protection cover 12, and the connecting ear is rotatably connected to the pull rod 13 through a rotating shaft. An arc rod is fixedly welded to the other side of the pull rod 13. The curvature of the arc rod is the same as the curvature of the curved surface of the protection cover 12. When the pull rod 13 moves to the vertical direction, the arc rod is held by hand to facilitate the insertion and removal of the protection cover 12.

[0027] Specifically, the wire locking device 6 includes an upper clamping plate 14 and a lower clamping plate 15, and a fixed ear is fixedly welded on the vertical inner wall of the storage box 1, and a rotating plate 16 is fixedly welded on the sides of the upper clamping plate 14 and the lower clamping plate 15.

The transverse threaded hole dug on the side of the storage box 1 is threadedly connected with a fixing bolt 19, and the fixing bolt 19 also passes through the transverse through hole dug on the rotating rod 17. A fixed threaded hole is also dug on the side of the storage box 1, and the fixed threaded hole is arranged directly below the rotating shaft of the hinged rotating rod 17. The transverse threaded hole and the fixed threaded hole can change the direction and position of the rotating rod 17, thereby changing the position of the universal wheel 18.

[0029] Specifically, two groups of symmetrically arranged side surfaces of the storage box 1 are each provided with a wire insertion hole 20, and the inner wall of the wire insertion hole 20 is glued with a rubber sleeve for protecting the wires to protect the wires.

The setting of the fixing plate 23 and the slot can prevent the protruding handles 24 from affecting the placement of the storage box 1. The two groups of handles 24 improve stability when carrying. The transverse section of the handle 24 is set to be U-shaped, and the rotating part of the handle 24 is hinged to the side wall of the slot of the fixing plate 23 through a rotating shaft.

[0032] Specifically, the vehicle-mounted charging device dedicated to the mobile cold storage opens the password lock 21 and the box cover 2, places a specific number of lithium battery blocks 3 in the storage box 1, and then selects the position of the slot where the vertical plate 8 is inserted according to the position of the lithium battery block 3.
