[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] This embodiment relates to a battery temperature reduction protection device, the overall structure of which is as follows: Figures 1 to 4 As shown, it includes a box body 1, and a cooling component 2, a placement component 3 and a battery module arranged in the box body 1. Among them, the placement component 3 includes a placement plate 321 arranged in the box body 1, and a heat dissipation hole 3210 arranged on the placement plate 321, and the battery module is arranged on the placement plate 321.

[0037] The cooling assembly 2 includes a mounting portion 21 disposed in the box body 1 and a cooling fan 22 disposed on the mounting portion 21. The mounting portion 21 is located below the placement plate 321, and the cooling fan 22 is located below the mounting portion 21 and is used to dissipate heat and cool the battery module.

[0038] It is worth mentioning that the battery module mentioned in this embodiment is preferably a lithium battery, and the bottom of the box body 1 of this embodiment may preferably be provided with a plurality of supporting feet 13 to improve the placement stability of the box body 1 and ensure the overall contact area of ​​the box body 1 with the external environment, thereby ensuring the heat dissipation effect.

[0039] Specifically, in this embodiment, as a preferred implementation form, see Figure 1 and Figure 2 As shown, the box body 1 includes a lower box body 11 and a box cover 12 hingedly mounted on the lower box body 11 , and a vent hole 10 is provided on at least one side of the box body 1 . Specifically, the vent holes 10 may be provided on the bottom of the lower box body 11 and the box cover 12 .

[0040] Here, by hingedly setting the box cover 12 on the lower box body 11, it is beneficial to ensure the convenience of opening and closing the box cover 12, and the air vents 10 are provided to ensure the smoothness of heat exchange between the box body 1 and the external environment, thereby facilitating the cooling fan 22 to transfer the heat generated by the battery module to the external environment.

[0041] Of course, in the specific implementation, in addition to the ventilation holes 10 provided on the bottom plate and the cover plate of the lower box body 11, the ventilation holes 10 may also be provided on the side walls of the lower box body 11 when necessary to increase the overall air permeability of the device.

[0042] Furthermore, as a preferred implementation form, the mounting portion 21 of this embodiment includes a mounting rod 211 disposed in the lower box body 11 , and a connecting member 212 disposed at the bottom of the mounting rod 211 , and the cooling fan 22 is disposed at the bottom of the connecting member 212 .

[0043] It can be understood that the mounting portion 21 is mainly composed of a mounting rod 211 and a connecting member 212, and the cooling fan 22 is arranged at the bottom of the connecting member 212, which can facilitate the arrangement and installation of the cooling fan 22, and make the structure simpler and easier to manufacture.

[0044] At the same time, in this embodiment, as a preferred implementation form, a plurality of cooling fans 22 are arranged between the mounting portion 21 and the lower box 11, so as to improve the cooling effect of the battery module. In the specific structure, the connecting member 212 can be a connecting rod, and the number and arrangement of the cooling fans 22 can be set and adjusted accordingly according to the actual cooling requirements. For example, the cooling fans 22 are set to four, and the four fans are distributed in a rectangular shape in the horizontal direction.

[0045] In addition, in this embodiment, as a preferred implementation form, see Figure 2 and Figure 3As shown, the placement component 3 includes a receiving portion arranged on the inner wall of the lower box body 11, and a support component 32 arranged on the receiving portion. The placement plate 321 is arranged on the support component 32 to form a first cavity 15 between the placement plate 321 and the cooling component 2, thereby increasing the heat dissipation space inside the box body 1, thereby allowing heat dissipation to a certain extent when the cooling fan 22 is not turned on.

[0046] Furthermore, as a preferred arrangement, the receiving portion of this embodiment includes side panels 31 disposed on each side wall in the lower box body 11. At the same time, the support assembly 32 includes support rods 322 disposed on each side panel 31, and each support rod 322 is supported below the placement plate 321.

[0047] In the specific implementation, in this embodiment, each side panel 31 is connected end to end to form a hollow portion in the middle. In this way, it can be understood that the receiving portion is mainly composed of multiple side panels 31, and a hollow portion is formed between each side panel 31, which can not only achieve cost reduction and lightweight design, but also ensure that the heat dissipation path of the heat dissipation fan 22 to the battery module is unobstructed.

[0048] When this embodiment is implemented, as a preferred implementation form, the number of support rods 322 can be specifically set to four and distributed at the four corners of the box body 1. Figure 2 and Figure 3 As shown, each support rod 322 has an extension section 3221 that penetrates upward from the top and extends out of the placement plate 321 , and a limiting space 3222 is enclosed between each extension section 3221 , and the limiting space 3222 is used to limit the horizontal movement of the battery module.

[0049] By setting the limiting space 3222, the installation stability of the battery module can be ensured, thereby helping to improve the protection effect of the battery module.

[0050] In addition, in this embodiment, as a preferred implementation form, still refer to Figure 2 As shown, the lower box body 11 includes a frame 111 and a breathable protective net 112 arranged at the bottom of the frame 111 , and the air holes 10 on the lower box body 11 are formed on the breathable protective net 112 .

[0051] By providing a breathable protective net 112, the air permeability of the box body 1 can be improved to ensure the overall heat dissipation effect of the device. At the same time, a second cavity 16 connected to the first cavity 15 can be formed between the breathable protective net 112 and the side plate 31, thereby increasing the heat dissipation space inside the box body 1, so as to improve the heat dissipation effect of the battery module when the cooling fan 22 is not turned on, or to facilitate the heat of the battery module to dissipate in the box body 1. When the cooling fan 22 is turned on, the heat in the box body 1 can be quickly dissipated.

[0052] Specifically, in this embodiment, as a preferred implementation form, refer again to Figure 1 and Figure 2 As shown, the box cover 12 is arranged on the top of the frame 111 through a hinge 14 assembly, and the hinge 14 assembly includes at least two hinges 14, and the hinge 14 can be a common hinge to ensure that the box cover 12 can be easily flipped open and closed.

[0053] At the same time, as a preferred implementation form, in this embodiment, a locking rod 121 is provided on the box cover 12, and a clamping groove 1111 is provided on the top of the frame 111, and the locking rod 121 is clamped in the clamping groove 1111. Here, the matching arrangement of the locking rod 121 and the clamping groove 1111 is simple in structure, which is conducive to locking and fixing the box cover 12.

[0054] In a specific implementation, a groove 122 can be set on the box cover 12, and the locking rod 121 can be set in the groove 122, and a boss compatible with the groove 122 can be set on the top of the frame 111, and the card slot 1111 is set on the boss, so that when the locking rod 121 is engaged in the card slot 1111, the box cover 12 and the lower box body 11 can have a good appearance after being closed.

[0055] Of course, the boss can be made of a plastic material with a certain elasticity commonly used by those skilled in the art to ensure the clamping stability of the locking rod 121 and the feasibility of repeated insertion and removal.

[0056] In addition, in this embodiment, as a preferred implementation form, see Figure 1 and Figure 4 As shown, the box body 1 is provided with a detection unit 4. The detection unit 4 includes a housing 41 and a temperature detection unit 44 disposed in the housing 41. The temperature detection unit 44 is used to detect the temperature in the box body 1. Thus, the cooling fan 22 can be turned on and off according to the need for temperature adjustment of the box body 1, which is beneficial to energy saving and consumption reduction.

[0057] Furthermore, in this embodiment, as a preferred implementation form, a control unit 45 connected to both the temperature detection unit 44 and the heat dissipation fan 22 is provided in the housing 41 .

[0058] The housing 41 is provided with a display screen 42 and an operation panel 43 connected to the control unit 45. The display screen 42 is used to display the temperature information detected by the temperature detection unit 44, and the operation panel 43 is used to input control information that can be recognized by the control unit 45 to control the opening and closing of the cooling fan 22.

[0059] It can be understood that the coordinated arrangement of the temperature detection unit 44 and the control unit 45 is conducive to realizing the automatic control of the battery cooling protection device, and the arrangement of the display screen 42 and the operation panel 43 can help improve the operator's operating convenience.

[0060] It should be noted that the components such as the temperature detection unit 44, the control unit 45, the display screen 42 and the operation panel 43 of this embodiment can all refer to related products or structures well known to those skilled in the art. For example, the temperature detection unit 44 uses a temperature sensor, and the operation panel 43 has a button connected to the control unit 45.

[0061] In this embodiment, first, the user can install the cooling assembly 2 by connecting the cooling fan 22 and the connecting member 212 through the coordination between the mounting rod 211 and the connecting member 212, and then install the mounting rod 211 inside the box body 1. When the temperature of the lithium battery rises, the cooling fan 22 can be used to directly cool the inside of the box body 1, thereby preventing the battery from overheating and prolonging the battery life.

[0062] Then, by installing the placement component 3, the support rod 322 and the placement plate 321 associated with it can be placed inside the box body 1 through the cooperation between the side plate 31 and the support rod 322. In this way, the battery and the box body 1 can be separated, and the heat dissipation holes 3210 also reduce the contact area between the battery and the placement plate 321, thereby enhancing the heat dissipation effect on the battery and facilitating the disassembly of the battery.

[0063] Furthermore, by installing the box cover 12 and setting air holes 10 on the cover, the air permeability of the box body 1 can be enhanced without affecting the overall heat dissipation performance of the device. Then, by installing a temperature sensor, the temperature inside the box body 1 can be monitored. When the temperature reaches the preset value, the control unit 45 will control the cooling component 2 to start, thereby reducing the energy consumption of the device and improving the practicability of the device.

[0064] The battery cooling protection device of this embodiment can help the battery module to dissipate heat and cool down through the setting of the cooling fan 22, so as to avoid overheating of the battery module and affect the safety of use, and improve its service life. At the same time, the setting of the placement component 3 is conducive to improving the placement stability of the battery module, so that the battery cooling protection device has good battery cooling and protection effects.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
