Description
Technical Field
[0001] This application relates to the technical field of battery insulation equipment, and particularly relates to an insulation board for new energy batteries. Background Art
[0002] Batteries are commonly used in daily life. To reduce potential safety hazards during battery use, a safe environment needs to be provided during the battery installation process. Most of the time when installing batteries, an insulation board is installed between the battery and other components.

Most insulation boards, except for the connection holes, are usually a single whole board that isolates the battery, and there is no other structure to assist the battery in dissipating heat. The heat generated during battery use is not easily dissipated, resulting in relatively low performance of the insulation board. Utility Model Content

Detailed implementation mode
[0032] The following further elaborates on this application in conjunction with the attached Figures 1-6 drawings.
[0033] Embodiment:
[0034] An embodiment of this application discloses an insulating plate for a new energy battery. Referring to Figure 1 , it includes a bottom plate 1. The bottom plate 1 consists of a first connecting plate 11 and a second connecting plate 12. A third connecting plate 13 is fixedly connected between the first connecting plate 11 and the second connecting plate 12. Fourth connecting plates 14 are fixedly connected to one end of the first connecting plate 11 away from the third connecting plate 13 and one end of the second connecting plate 12 away from the third connecting plate 13. A heat dissipation structure 2 is provided on the third connecting plate 13.
[0035] Referring to Figure 2 , Figure 3 and Figure 4 , positioning posts 15 are provided on the first connecting plate 11, the second connecting plate 12 and the third connecting plate 13. Connecting grooves 151 are provided at the connection positions of each positioning post 15. The side where the positioning posts 15 are installed is connected to the rib member as the installation surface, and the back of the positioning posts 15 in contact with the battery is the insulating surface. On one side of the installation surface, the first connecting plate 11 and the second connecting plate 12 are on the same horizontal plane. The horizontal plane height of the third connecting plate 13 is lower than the horizontal plane height of the first connecting plate 11 and the second connecting plate 12. There is a first step 131 between the third connecting plate 13 and the first connecting plate 11 and the second connecting plate 12. The horizontal plane height of the fourth connecting plate 14 is higher than the horizontal plane height of the first connecting plate 11 and the second connecting plate 12. There is a second step 141 between the fourth connecting plate 14 and the first connecting plate 11 and the second connecting plate 12.
[0036] A first connection port 132 is formed on the third connection plate 13. The first connection ports 132 are arranged in a tic-tac-toe pattern between the first connection plate 11 and the second connection plate 12. The heat dissipation structure 2 includes a contact panel 21. The contact panel 21 is fixedly connected to the third connection plate 13. The contact panel 21 is arranged in a cross shape between the tic-tac-toe-shaped first connection ports 132. The height of the horizontal plane where the contact panel 21 is located is higher than the height of the horizontal planes where the first connection plate 11 and the second connection plate 12 are located. The top surface of the contact panel 21 is on the same horizontal plane as the top surface of the fourth connection plate 14. There is a third step 211 between the contact panel 21 and the third connection plate 13, and the height of the third step 211 is higher than the height of the first step 131. First avoidance plates 22 are fixedly connected to both ends of the contact panel 21 close to the first connection plate 11 and the second connection plate 12 respectively. The first avoidance plates 22 and the positioning posts 15 on the third connection plate 13 are arranged alternately. The height of the horizontal plane where the first avoidance plates 22 are located is higher than the height of the horizontal plane where the third connection plate 13 is located, and the height of the horizontal plane where the first avoidance plates 22 are located is lower than the height of the horizontal planes where the first connection plate 11 and the second connection plate 12 are located. There are fourth steps 221 between the first avoidance plates 22 and the first connection plate 11 and between the first avoidance plates 22 and the second connection plate 12 respectively. There is a fifth step 222 between the first avoidance plates 22 and the contact panel 21.
[0037] Fifth connection plates 23 are fixedly connected between the fourth connection plate 14 and the first connection plate 11 and between the fourth connection plate 14 and the second connection plate 12 respectively. The fifth connection plates 23 are on the same horizontal plane as the third connection plate 13. There are sixth steps 231 between the fifth connection plates 23 and the first connection plate 11 and between the fifth connection plates 23 and the second connection plate 12 respectively. Second connection ports 232 are formed on the fifth connection plates 23. Two second connection ports 232 are arranged in a Japanese character pattern as a group on the fifth connection plates 23. Second avoidance plates 24 are arranged between each group of second connection ports 232. The second avoidance plates 24 are fixedly connected to the fourth connection plate 14 and the first connection plate 11 at the same time. The second avoidance plates 24 are on the same horizontal plane as the first avoidance plates 22. There is a seventh step 241 between the second avoidance plates 24 and the fifth connection plates 23. There is an eighth step 243 between the second avoidance plates 24 and the fourth connection plate 14. There are ninth steps 244 between the second avoidance plates 24 and the corresponding first connection plate 11 and second connection plate 12 respectively. Positioning posts 15 are also installed on the fifth connection plates 23, and connection grooves 151 are arranged at the connection positions of each positioning post 15. The second avoidance plates 24 and the positioning posts 15 on the fifth connection plates 23 are arranged at intervals.
[0038] The sheet metal part is provided with positioning holes for installing the insulating plate. The insulating plate is quickly positioned and installed on the sheet metal part through the positioning posts 15. The battery is connected and fixed or connected for use with the outside through the first connection port 132. The contact panel 21 separates each group of first connection ports 132 through the third step 211 to prevent interference between each group of first connection ports 132. When the insulating plate is connected to the sheet metal part, the contact panel 21 and the fourth connection plate 14 are attached and pressed tightly against the sheet metal part. At this time, there are gaps between the first connection plate 11, the second connection plate 12, the third connection plate 13, and the fifth connection plate 23 and the sheet metal part. Therefore, the heat between the insulating plate and the sheet metal part can dissipate to both sides of the sheet metal part through the gaps, facilitating the cooling of the working environment of the battery.
[0039] Since there are fourth steps 221 between the first avoidance plate 22 and the second connection plate 12, and there is a fifth step 222 between the first avoidance plate 22 and the contact panel 21, there is a gap between the first avoidance plate 22 and the sheet metal part. The heat at the position of the first connection port 132 can communicate through the gap between the first avoidance plate 22 and the sheet metal part. The heat flows between the first connection ports 132 and quickly dissipates to both sides through the gap between the first avoidance plate 22 and the sheet metal part, enhancing the circulation performance between the positions of each group of first connection ports 132 and enhancing the heat dissipation effect. There are ninth steps 244 between the second avoidance plate 24 and the first connection plate 11 and the second connection plate 12, and there is an eighth step 243 between the second avoidance plate 24 and the fourth connection plate 14, making the gap between the second avoidance plate 24 and the sheet metal part increase. While the heat of the second connection port 232 flows to the first connection plate 11 and the second connection plate 12 and dissipates, it also facilitates the flow of heat between the second connection ports 232, strengthening the overall heat dissipation effect of the insulating plate and enhancing the service performance of the insulating plate.
[0040] Refer to Figure 5 and Figure 6 , on one side of the insulating surface, the first connection plate 11 and the second connection plate 12 are on the same horizontal plane. The height of the horizontal plane where the third connection plate 13 is located is higher than the height of the horizontal planes where the first connection plate 11 and the second connection plate 12 are located. The fifth connection plate 23 is on the same horizontal plane as the third connection plate 13. The fourth connection plate 14 is on the same horizontal plane as the contact panel 21. A first diversion groove 25 is provided at the rear side of the third connection plate 13 corresponding to the contact panel 21. A second diversion groove 26 is provided at the rear side of the third connection plate 13 corresponding to the first avoidance plate 22. The second diversion groove 26 communicates with the corresponding first connection plate 11 and the second connection plate 12. The second diversion groove 26 communicates with the first diversion groove 25. A third diversion groove 27 is provided at the rear side of the fifth connection plate 23 corresponding to the second avoidance plate 24. The third diversion groove 27 communicates with the corresponding first connection plate 11 and the second connection plate 12.
[0041] The positioning post 15 is provided with a hollow groove 152 on one side of the insulating surface. In this embodiment, after all the positioning posts 15 are installed into the positioning holes of the sheet metal parts, the positioning posts 15 will be heated and riveted. The positioning posts 15 are extruded and fitted onto the sheet metal parts, so that the insulating board is stuck on the sheet metal parts and is not easy to fall off. And through the setting of the connecting groove 151, it plays a role of buffering and error tolerance during the hot riveting of the positioning post 15, preventing the influence on the installation of the insulating board caused by the rib-like structure that is prone to appear at the root during the hot pressing and forming of the positioning post 15. The connecting groove 151 can thus allow small ribs to appear or allow slight incomplete forming, reducing the influence on the subsequent battery assembly connection. It provides a volume change space for the positioning post 15 when it expands due to heat, preventing the positioning post 15 from expanding in volume due to heat change and pushing out of the positioning hole on the sheet metal part, causing the insulating board to separate from the sheet metal part.
[0042] When the insulating board is connected to the battery, the battery is pressed against the third connecting plate 13 and the fifth connecting plate 23. There are gaps between the battery and the first connecting plate 11, the second connecting plate 12, the contact panel 21, the first avoidance plate 22, the second avoidance plate 24, and the fourth connecting plate 14. The heat generated at the position area where the battery is pressed against the third connecting plate 13 enters into the first diversion groove 25. The heat in the first diversion groove 25 is directly dissipated to both sides of the insulating board in the direction of the arrow m as shown Figure 6 or passes through the second diversion groove 26 in the direction of the arrow n and flows into the gap formed between the first connecting plate 11 or the second connecting plate 12 and the battery. The heat at the gap between the first connecting plate 11 and the second connecting plate 12 and the battery is dissipated in the direction indicated by the arrow p, or flows through the third diversion groove 27 and is dissipated after passing through the fourth connecting plate 14, enabling the heat at the position of the first connection port 132 and the heat at other parts between the battery and the insulating board to be dissipated in multiple directions, enhancing the heat circulation and accelerating the heat dissipation, and enhancing the performance of the insulating board.
[0043] The implementation principle of the embodiment of this application is as follows: The insulating board is installed on the sheet metal part through the rapid positioning of the positioning post 15, and gaps are formed between the side that fits and abuts against the sheet metal part and the first connecting plate 11, the second connecting plate 12, the third connecting plate 13, and the fifth connecting plate 23, enhancing the heat circulation performance between the sheet metal part and the insulating board; on the side where the battery contacts the insulating board, the battery is pressed against the third connecting plate 13 and the fifth connecting plate 23. There are gaps between the battery and the first connecting plate 11, the second connecting plate 12, the contact panel 21, the first avoidance plate 22, the second avoidance plate 24, and the fourth connecting plate 14. The heat flows and dissipates through the gaps communicated between the first diversion groove 25, the second diversion groove 26, and the third diversion groove 27, which can accelerate the heat dissipation of the insulating board and enhance the performance of the insulating board.
[0044] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
