Description

Technical Field

[0001] This utility model relates to the field of BMS battery management system technology, specifically a heat dissipation device for BMS battery management system. Background Technology

[0002] Battery Management System (BMS), commonly known as a battery nanny or battery manager, is mainly used for intelligent management and maintenance of each battery cell, monitoring the battery status, preventing overcharging and over-discharging to extend battery life. BMS is the link between the battery and the user, responsible for monitoring, controlling and managing various battery performance aspects to ensure safe, stable and long-life operation of the battery.

[0003] For example, utility model application CN201921534268.8 discloses a heat dissipation device for a BMS battery management system. This heat dissipation device uses a motor to drive a fan blade to rotate, thereby accelerating the airflow inside the housing. The airflow enters the housing from the air inlet and, after cooling the BMS battery management system, is discharged from the exhaust port. This ensures that the BMS battery management system will not be affected by overheating during long-term operation, thus avoiding certain safety hazards. However, similar heat dissipation devices may allow foreign objects to enter the housing along with the airflow, potentially causing unnecessary damage to internal components. Furthermore, the entire device cannot be stably and securely stacked when used or stored in combination, requiring the use of a storage rack, which limits the ease of use of the structure.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a heat dissipation device for a BMS battery management system. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation device for a BMS battery management system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation device for a BMS battery management system, comprising a protective box and an upper buffer plate. The upper buffer plate is horizontally connected to the top of the protective box, and an upper shock-absorbing pad is attached to the top surface of the upper buffer plate. A lower buffer plate is horizontally connected to the bottom of the protective box, and a lower shock-absorbing pad is attached to the bottom surface of the lower buffer plate. A support column is vertically connected between the lower buffer plate and the upper buffer plate, and support piles are symmetrically installed on the bottom of the lower buffer plate. Cooling fans are installed on both the left and right sides of the protective box, and a first dustproof mesh plate is provided between the cooling fans and the protective box. A second dustproof mesh plate is installed on the rear side of the protective box. Connecting blocks are inserted on both the left and right sides of the upper buffer plate.

[0007] Furthermore, the protective box is fixedly connected to both the upper and lower buffer plates, and the support pile is fixedly connected to the lower buffer plate. The protective box is made of a material with good thermal conductivity.

[0008] Furthermore, the protective box has groove structures on both the left and right sides that match the surface structure of one side of the first dustproof mesh plate, and the protective box also has insertion structures on both the left and right sides that match the surface structure of one side of the cooling fan.

[0009] Furthermore, the support piles are vertically installed at the four opposite corners between the upper and lower buffer plates, and the upper end of the support piles vertically penetrates the four opposite corners of the upper buffer plate and extends out a section, while the bottom end of the support piles is installed at the four opposite corners of the lower buffer plate using a threaded connection structure.

[0010] Furthermore, the upper buffer plate and the upper shock-absorbing pad are provided with insertion holes at the four opposite corners of their tops, which are matched with the surface structure of the support pile. The lower buffer plate and the lower shock-absorbing pad are provided with insertion holes at the four opposite corners of their bottoms, which are matched with the surface structure of the upper end of the support column.

[0011] Furthermore, the cooling fan is installed on the left and right sides of the protective box using a plug-in structure, and the first dustproof mesh is installed on the left and right sides of the protective box using a magnetic structure.

[0012] Furthermore, the second dustproof mesh and the protective box are integrated into one structure, and the support piles are fixedly connected to the four opposite corners of the bottom of the lower buffer plate.

[0013] Furthermore, the upper buffer plate has symmetrically arranged insertion holes on its left and right sides that match the surface structure of the lower end of the connecting plug, and the lower buffer plate has symmetrically arranged insertion holes on its left and right sides that match the surface structure of the upper end of the connecting plug.

[0014] This utility model provides a heat dissipation device for a BMS (Battery Management System), which has the following beneficial effects:

[0015] 1. This utility model provides good structural protection and structural support for the BMS battery management system installed inside the protective box by connecting an upper buffer plate and a lower buffer plate to the upper and lower sides respectively, and vertically installing support columns at four opposite points between the upper and lower buffer plates. This ensures the service life and operational stability of the BMS battery management system inside the protective box. The upper and lower shock-absorbing pads can prevent excessive wear on the surfaces of the upper and lower buffer plates, and further improve the vibration absorption and buffering effect of the structure, thereby improving the protective effect of the structure.

[0016] 2. This utility model features an upper buffer plate covered with upper shock-absorbing pads, with four opposite corners having insertion holes matching the surface structure of the support piles. Simultaneously, a lower buffer plate covered with lower shock-absorbing pads has four opposite corners having insertion holes matching the upper surface structure of the support column. Therefore, by using these structures, the support piles at the bottom of the lower buffer plate can be inserted onto the top surface of the upper buffer plate, and the support columns extending from the four opposite corners of the upper buffer plate can be inserted into the bottom of the lower buffer plate. This allows for the creation of multiple stacked structures within the entire device, ensuring accurate splicing and preventing displacement. The use of connecting blocks further enhances the stability of the stacked assembly, facilitating combined use or storage.

[0017] 3. This utility model, through the use of a plug-in connection method, symmetrically arranges cooling fans on the left and right sides of the protective box. Utilizing the operation of the cooling fans, in conjunction with the second dustproof mesh plate structure on the rear side of the protective box, it can provide maximum structural heat dissipation and ventilation for the BMS battery management system inside the protective box. The first dustproof mesh plate, located between the protective box and the cooling fans, in conjunction with the structure of the second dustproof mesh plate, ensures that external foreign objects cannot easily enter the interior of the protective box without affecting ventilation and heat dissipation. Since the first dustproof mesh plate is installed on the left and right sides of the protective box using a magnetic structure, both the cooling fans and the first dustproof mesh plate have flexible structural disassembly and assembly capabilities, facilitating structural maintenance.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 4 As shown, a heat dissipation device for a BMS battery management system includes a protective box 1 and an upper buffer plate 2. The upper buffer plate 2 is horizontally connected to the top of the protective box 1, and an upper shock-absorbing pad 3 is attached to the top surface of the upper buffer plate 2. A lower buffer plate 4 is horizontally connected to the bottom of the protective box 1, and a lower shock-absorbing pad 5 is attached to the bottom surface of the lower buffer plate 4. A support column 6 is vertically connected between the lower buffer plate 4 and the upper buffer plate 2, and support piles 7 are symmetrically installed on the left and right sides of the bottom of the lower buffer plate 4. Cooling fans 8 are installed on both the left and right sides of the protective box 1, and a first dustproof mesh plate 9 is provided between the cooling fans 8 and the protective box 1. A second dustproof mesh plate 10 is installed on the rear side of the protective box 1. Connecting blocks 11 are inserted on both the left and right sides of the upper buffer plate 2. The protective box 1 is fixedly connected to the upper buffer plate 2 and the lower buffer plate 4. The support pile 7 is fixedly connected to the lower buffer plate 4. The protective box 1 is made of a good thermally conductive material. The upper buffer plate 2 and the lower buffer plate 4 are connected to the upper and lower sides of the protective box 1 respectively. At the same time, support columns 6 are vertically installed at four opposite points between the upper buffer plate 2 and the lower buffer plate 4. This can provide good structural protection and structural support for the BMS battery management system installed inside the protective box 1.

[0025] like Figures 1 to 4 As shown, the protective box 1 has grooves on both the left and right sides that match the surface structure of one side of the first dustproof mesh plate 9. The protective box 1 also has inserts on both the left and right sides that match the surface structure of one side of the cooling fan 8. Supports 7 are vertically positioned at the four opposite corners between the upper buffer plate 2 and the lower buffer plate 4. The upper end of the support 7 vertically penetrates the four opposite corners of the upper buffer plate 2 and extends outwards. The bottom end of the support 7 is threaded and installed at the four opposite corners of the lower buffer plate 4. The upper buffer plate 2 and the upper shock-absorbing pad 3 have insertion holes at the four opposite corners that match the surface structure of the support 7. The lower buffer plate 4 and the lower shock-absorbing pad 5 have insertion holes at the four opposite corners that match the surface structure of the upper end of the support column 6. This allows the support 7 at the bottom of the lower buffer plate 4 to be inserted onto the top surface of the upper buffer plate 2, and simultaneously the support columns 6 extending from the four opposite corners of the upper buffer plate 2 to be inserted into the bottom of the lower buffer plate 4, thus achieving a multi-layered stacked combination structure for the entire device.

[0026] like Figures 1 to 4As shown, the cooling fan 8 is installed on the left and right sides of the protective box 1 using a plug-in structure, and the first dustproof mesh plate 9 is installed on the left and right sides of the protective box 1 using a magnetic structure. The second dustproof mesh plate 10 and the protective box 1 are integrated into one structure. The support piles 7 are fixedly connected to the four diagonal points at the bottom of the lower buffer plate 4. The upper buffer plate 2 has symmetrically opened insertion holes on the left and right sides that match the lower surface structure of the connecting plug 11, and the lower buffer plate 4 has symmetrically opened insertion holes on the left and right sides that match the upper surface structure of the connecting plug 11. The first dustproof mesh plate 9, which is set between the protective box 1 and the cooling fan 8, together with the structure of the second dustproof mesh plate 10, can ensure that foreign objects do not easily enter the interior of the protective box 1 without affecting ventilation and heat dissipation. Since the first dustproof mesh plate 9 is installed on the left and right sides of the protective box 1 using a magnetic structure, both the cooling fan 8 and the first dustproof mesh plate 9 have flexible structural disassembly and assembly.

[0027] In summary, as Figures 1 to 4 As shown, when using the BMS battery management system heat dissipation device, first install each structural component of the BMS battery management system inside the protective box 1, ensuring the spacing between them and the stability after installation. Then, install two sets of first dustproof mesh plates 9 on the left and right sides of the protective box 1 respectively using a magnetic structure. Then, fix two sets of cooling fans 8 on the left and right sides of the protective box 1 through a plug-in structure, and place the first dustproof mesh plates 9 between the protective box 1 and the cooling fans 8.

[0028] Then the entire device can be placed stably on the platform using the four diagonal supports 7 at the bottom of the lower buffer plate 4, and electrically connected to the battery components that need to be managed. If multiple devices need to be stacked, one device can be placed on top of another device. During this process, the supports 7 at the bottom of one set of lower buffer plates 4 are inserted into the matching insertion holes on the top surface of the other set of upper buffer plates 2. At the same time, the tops of the support columns 6 extending from the four diagonal supports of one set of upper buffer plates 2 are inserted into the matching insertion holes at the bottom of the other set of lower buffer plates 4. This ensures the stability of the two devices after stacking. Meanwhile, the upper shock-absorbing pads 3 and lower shock-absorbing pads 5 that fit together between the two devices will provide structural buffering and shock absorption to a certain extent.

[0029] If it is necessary to ensure the firmness of the connection between the stacked devices, four sets of connecting blocks 11 can be arranged in the horizontal direction, with two sets on each of the left and right sides of the device, and inserted into the sides of the upper buffer plate 2 and lower buffer plate 4 of the two stacked devices, so as to play the role of structural locking and avoid unnecessary structural loosening.

Many modifications and variations will be apparent to those skilled in the art.
