All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] like Figure 1-4 As shown, this embodiment proposes a battery intelligent management device, including a housing 1, a battery cell 2 disposed on the inner wall surface of the housing 1, a cavity formed between the battery cell 2 and the housing 1 as an inner cavity 3, and a temperature control structure 4 connected to the inner wall of the housing 1. The temperature control structure 4 includes a blower assembly and an adjustment assembly. The blower assembly is used to blow out air to dissipate heat, and the adjustment assembly is used to adjust the size of the heat dissipation opening according to the heat inside the housing 1. A switch button 5 is provided on the outer surface of one end of the housing 1, and an indicator light 6 is provided on the outer surface of the housing 1. An inner bracket 7 is detachably connected between the inner wall surface of the housing 1 and the battery cell 2.

[0020] The blower assembly includes a heat dissipation hole 41 on the outer surface of the housing 1, a variable frequency motor 42 fixedly connected to the inner wall surface of the housing 1, a shaft 43 fixedly connected to the output end of the variable frequency motor 42, and blades 44 fixedly connected to the outer surface of the shaft 43; a fixing plate 45 fixedly connected to the inner wall surface of the housing 1, a push spring 46 connected to the outer surface of the fixing plate 45, a movable plate 47 movably connected to the inner side of the housing 1 corresponding to the heat dissipation hole 41, end plates 48 fixedly connected to both sides of the movable plate 47, a matching hole 49 opened on the outer surface of the movable plate 47, a trigger switch 410 fixedly connected to the inner wall surface of the housing 1 near the end plate 48, and a positioning member 411 fixedly connected to the inside of the trigger switch 410 near the end plate 48.

[0021] The heat dissipation holes 41 are arranged in several groups in a ring array. The variable frequency motor 42 is located on the inner side of the housing 1, corresponding to the center of the heat dissipation holes 41. The number of blades 44 is arranged in several groups in a ring array. The push spring 46 is arranged horizontally, and the elastic ends of the push spring 46 are fixedly connected to the fixed plate 45 and the end plate 48 respectively. The push spring 46 is a spring that expands when heated and contracts when cooled. The movable plate 47 is used to block the opening of the heat dissipation holes 41. The set of end plates 48 away from the push spring 46 is used to push the trigger switch 410 to open or close. The positioning member 411 is used to limit the range of left and right movement of the movable plate 47 and the end plate 48. The movement position of the movable plate 47 and the end plate 48 is adjusted by the expansion and contraction of the push spring 46. The size of the opening connecting the heat dissipation holes 41 with the inner and outer parts of the housing 1 is adjusted by the movement of the movable plate 47 and the end plate 48. The trigger switch 410 and the variable frequency motor 42 are electrically connected.

[0022] In this embodiment, during the use of the battery intelligent management device, the size of the heat dissipation opening can be freely adjusted according to the temperature of the battery cell 2 inside the casing 1 during actual use. At the same time, when the temperature exceeds the set range, air can be blown to dissipate heat inside the casing 1, preventing excessive internal heat. In addition, the internal temperature can be kept from escaping in cold environments, thereby effectively maintaining the battery's performance.

[0023] In summary, the working principle of this utility model is as follows: During use, the user can start or stop the battery using the switch button 5. In hotter environments, such as above 30°C, the push spring 46 will expand due to heat. The push spring 46 pushes the end plate 48, which in turn pushes the movable plate 47 to move. At this time, the opening of the heat dissipation hole 41 is exposed. The greater the heat, the larger the size of the exposed opening of the heat dissipation hole 41 becomes. The larger the opening, the better the heat dissipation effect on the battery cell 2. When the push spring 46 expands to the maximum distance limited by the positioning member 411, the other end plate 48 will push the trigger switch 410. At this time, the trigger switch 410 will be activated, and the trigger switch 410 will start the variable frequency motor 42. The variable frequency motor 42 drives the shaft 43 to rotate, and the shaft 43 drives the blades 44 to blow air, thereby achieving a high-efficiency heat dissipation effect. The variable frequency motor 42 can automatically adjust the air force blown out for heat dissipation as needed. In cold environments, such as below 10°C, the internal temperature of the outer casing 1 will not be much, and the top spring 46 will not expand when it contracts. At this time, the opening of the heat dissipation hole 41 on the surface of the outer casing 1 will not be connected to the inside of the outer casing 1. Therefore, the heat generated by the battery cell 2 during use will not be dissipated to the outside through the heat dissipation hole 41, and it can still maintain its performance in cold environments.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
