Lithium batteries have many advantages such as high energy density, high output power, long charge and discharge life, no pollution, wide operating range and low self-discharge. Lithium battery packs are usually composed of multiple lithium batteries connected in series or parallel to enhance the power supply performance of lithium batteries.

The contact area between the cooling fan and the air and the lithium battery pack is small, and the heat dissipation effect is limited, which cannot guarantee the heat dissipation effect well. At the same time, the fixing and protection of the lithium battery pack is not good enough, which may cause certain damage to the lithium battery pack during transportation and movement.

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a lithium battery pack device, including a mounting shell 1, a connecting socket 2 is fixedly installed on the left side of the mounting shell 1, a heat dissipation component 3 located in the mounting shell 1 is fixedly installed on the bottom of the mounting shell 1, a battery module 4 is movably installed on the inner side of the heat dissipation component 3, mounting holes 5 are opened at four corners of the top of the mounting shell 1, a fixing component 6 is movably installed on the top of the mounting shell 1, and fixing bolts 7 located in the mounting holes 5 are threadedly installed at the four corners of the top of the fixing component 6.

[0024] When the battery module 4 is installed and fixed by the heat dissipation component 3 arranged in the installation shell 1, the battery module 4 is independently separated and fixed. When in use, the heat dissipation component 3 is located on the side of the independent battery module 4 to conduct the generated heat and the heat is discharged from the bottom of the installation shell 1 through the heat dissipation component 3 and the vent 8. The heat dissipation effect of the battery module 4 is improved by heat conduction and heat dissipation of the independent battery module 4. At the same time, the independent battery module 4 is clamped by the fixing component 6 arranged on the top of the installation shell 1 through the fixing component 6 and the heat dissipation component 3, thereby preventing the battery module 4 from moving during movement and improving the fixing and protection effect of the battery module 4.

[0025] like Figure 3 and Figure 4 As shown, the heat dissipation assembly 3 includes a connecting base plate 31 and a limiting baffle 32. The connecting base plate 31 is fixedly installed at the bottom of the mounting shell 1, and the limiting baffle 32 is fixedly connected to the top of the connecting base plate 31. The top of the connecting base plate 31 is fixedly connected with a heat dissipation baffle 33, and the heat dissipation baffle 33 is equidistantly arranged on the inner side of the limiting baffle 32. The battery module 4 is movably connected to the top of the connecting base plate 31, and the battery module 4 is separated by the heat dissipation baffle 33. A heat dissipation cavity 34 is opened inside the connecting base plate 31, and a heat dissipation fan 35 is fixedly installed at the bottom of the connecting base plate 31.

[0026] The heat dissipation baffle 33 includes a plate frame 331 , an empty slot 332 , a heat conducting fin 333 and a clamping block 334 . The empty slot 332 is opened inside the plate frame 331 , the heat conducting fin 333 is fixedly connected in the empty slot 332 , and the clamping block 334 is fixedly connected to the top of the plate frame 331 .

[0027] The heat dissipation baffle 33 is clamped and fixed on the connecting base plate 31, and the battery module 4 is fixedly installed on the connecting base plate 31, and the battery module 4 is separated and fixed by the heat dissipation baffle 33 and the limit baffle 32. The plate frame 331 arranged at intervals on the side of the battery module 4 conducts heat to the heat-conducting fins 333 in the slots 332, and is connected with the heat dissipation cavity 34 through the slots 332, and the heat is discharged outwardly through the heat dissipation fan 35. While the heat is discharged through the heat dissipation fan 35, the air entering the installation shell 1 through the ventilation hole 8 also enters the inner side of the slots 332, and is discharged from the heat dissipation fan 35 after heat exchange between the air and the heat-conducting fins 333. The battery module 4 is separated and the air flow between each battery module 4 is increased, thereby improving the heat dissipation effect of the battery module 4.

[0028] like Figure 5 As shown, the fixing assembly 6 includes a top cover 61, a damping sleeve 62, a support spring 63, a clamping frame 64, an anti-skid pad 65 and a clamping hole 66. The top cover 61 is installed on the top of the mounting shell 1 by means of fixing bolts 7. Two symmetrically arranged damping sleeves 62 are fixedly installed on the bottom of the top cover 61. The outsides of the two damping sleeves 62 are movably sleeved with support springs 63. The bottoms of the two damping sleeves 62 are fixedly connected with a clamping frame 64. The inside of the clamping frame 64 is fixedly installed with an anti-skid pad 65. The insides of the clamping frame 64 and the anti-skid pad 65 are provided with clamping holes 66.

[0029] By installing the top cover 61 on the top of the mounting shell 1 using the fixing bolts 7, the clamping block 334 is clamped into the clamping hole 66, and the clamping frame 64 is clamped on the top and front and rear sides of the battery module 4 and the heat dissipation baffle 33. The battery module 4 is clamped and limited by the anti-slip pad 65 and the clamping frame 64, thereby ensuring that the battery module 4 is firmly installed during the movement process.

[0030] like Figure 3 As shown, the heat conducting fins 333 are equidistantly arranged in the empty slots 332 , and the empty slots 332 are communicated with the heat dissipation cavity 34 .

[0031] By equidistantly arranging the heat-conducting fins 333 , the air entering the empty slots 332 contacts the heat-conducting fins 333 and carries the heat into the heat-dissipating cavity 34 for discharge, thereby ensuring the heat dissipation effect.

[0032] like Figure 3 As shown, a heat dissipation hole corresponding to the position of the battery module 4 is opened on the top of the connecting bottom plate 31 .

[0033] The heat dissipation effect is improved by setting the heat dissipation holes.

[0034] like Figure 2 As shown, ventilation holes 8 corresponding to the positions of the heat dissipation baffles 33 are provided on both the front and rear sides of the mounting housing 1 .

[0035] The air intake through the vents 8 cooperates with the heat dissipation baffle 33 to increase the heat exchange efficiency of the battery module 4, thereby improving the heat dissipation effect.

[0036] like Figure 5 As shown, the card frame 64 is arranged in a "C" shape, and a rubber pad 9 is fixedly installed on the bottom of the mounting shell 1.

[0037] The "C"-shaped clamping frame 64 is clamped on the front and rear sides of the battery module 4, and the heat dissipation partition 33 is used to limit the battery module 4, thereby ensuring the stability of the installation of the battery module 4, and the rubber pad 9 can provide a shock-absorbing effect when moving.

[0038] The working principle of the lithium battery pack device is described in detail below.

[0039] like Figures 1 to 5As shown, by clamping and fixing the heat dissipation baffle 33 on the connecting bottom plate 31, and by fixing the battery module 4 on the connecting bottom plate 31, the battery module 4 is separated and fixed by the heat dissipation baffle 33 and the limit baffle 32, and is used by connecting the battery module 4 with the connecting socket 2, by installing the top cover 61 on the top of the mounting shell 1 using the fixing bolts 7, so that the clamping block 334 is clamped into the clamping hole 66, so that the clamping frame 64 is clamped on the top and the front and rear sides of the battery module 4 and the heat dissipation baffle 33, when in use, the battery module 4 generates a lot of heat, and the plate frame body 3 is arranged at intervals on the side of the battery module 4. The heat is transferred from the heat transfer housing 1 to the heat transfer fins 333 in the slots 332, and is connected to the heat dissipation cavity 34 through the slots 332, and is discharged outwardly through the heat dissipation fan 35. While the heat is discharged through the heat dissipation fan 35, the air in the mounting shell 1 through the vents 8 also enters the inner side of the slots 332, and is discharged from the heat dissipation fan 35 after heat exchange between the air and the heat transfer fins 333. When moving, the rubber pad 9 has elasticity, and the anti-skid pad 65 provided in the card frame 64 improves the stability effect, and cooperates with the heat dissipation partition 33 and the limit baffle 32 to stabilize the battery module 4 to prevent damage to the battery module 4.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
