Description

Technical Field

[0001] The utility model relates to the field of battery covers, in particular to a high temperature resistant blister cover for new energy power batteries. Background Art

[0002] Spontaneous combustion of batteries is essentially thermal runaway of the batteries. Thermal runaway generally means that for some reason, the battery temperature rises uncontrollably, breaking through the critical point, catching fire or even exploding. That is, the battery is in an overheated state, and the battery temperature is out of control. Several important reasons for thermal runaway are: During the driving of electric vehicles, a collision of the vehicle may cause foreign objects to invade the interior of the power battery, causing an internal short circuit in the battery. Heat accumulation in the internal short circuit will bring the risk of spontaneous combustion. During the charging process of electric vehicles, due to overcharging or failure of the cooling system, the internal temperature of the battery is too high, which brings the risk of spontaneous combustion.

[0003] In actual use, new energy batteries often need regular maintenance to ensure the safety of the batteries. During maintenance, traditional covers will make the disassembly work more cumbersome and require the removal of a large number of screws, resulting in low maintenance efficiency.

[0004] Therefore, it is necessary to propose a high temperature resistant blister cover for new energy power batteries to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-7 A high temperature resistant blister cover for a new energy power battery is shown, comprising a cover plate cover plate structure 1, the cover plate cover plate structure 1 is used to protect the new energy battery, and is sleeved on the outside of the battery, thereby reducing the possibility of the battery being damaged, and can also prevent rainwater and the like from entering the inside of the battery, the lower end of the cover plate cover plate structure 1 is sleeved with a cover plate fixing plate structure 2, the cover plate fixing plate structure 2 is used to install the device on an external mounting frame, the cover plate cover plate structure 1 comprises a cover plate side plate 3, the top end of the cover plate side plate 3 is integrally formed with a cover plate top plate 4, the cover plate side plate 3 comprises a side plate inner wall 31 and a side plate outer wall 32, the side plate inner wall 31 and the side plate outer wall 32 form The first cavity, a plurality of V-shaped connectors 33 are provided in the middle position of the side panel inner wall 31 and the side panel outer wall 32, and the two ends of the V-shaped connector 33 are respectively fixedly mounted on the side panel inner wall 31 and the side panel outer wall 32, and the V-shaped connector 33 has a plurality of inclined surfaces. When an object hits the side panel 3, the V-shaped connector 33 can play a buffering role. The plurality of V-shaped connectors 33 separate the first cavity into a plurality of second cavities 34, and the interior of the second cavity 34 is filled with a buffer 35. When an external object hits the side panel 3, extrusion is generated between the buffers 35 to reduce the impact force, thereby better protecting the internal battery.

[0026] Most traditional cover plates are made of plastic and are relatively thick and heavy, which makes them very cumbersome to disassemble. In addition, the thermal conductivity of the cover plate material is relatively poor, which can easily cause the battery temperature to be too high and cause danger. Therefore, by providing a V-shaped connector, the amount of material required for the entire cover plate can be reduced, and the overall strength of the cover plate can still be maintained. In addition, because the interior is divided into multiple cavities, the overall weight of the cover plate is reduced, making it easier to disassemble and maintain. The temperature of the battery surface can be quickly transferred to the outside of the cover plate, and the gaps between the buffers give the cover plate a certain buffering force.

[0027] The cover plate fixing plate structure 2 includes a U-shaped fixing plate 5, a disassembly fixing plate 6 is provided at the opening of the U-shaped fixing plate 5, symmetrical mounting plates 61 are fixedly installed at both ends of the disassembly fixing plate 6, a groove corresponding to the mounting plate 61 is opened at the open end of the U-shaped fixing plate 5, and the mounting plate 61 is slidably clamped in the inside of the groove, and the disassembly fixing plate 6 and the U-shaped fixing plate 5 surround a rectangular frame, and the rectangular frame is used to clamp the cover plate side plate 3, and a plurality of evenly distributed clamping plates 30 are fixedly installed at the bottom end of the outer circle of the cover plate side plate 3, sliding grooves 51 are opened on both sides of the U-shaped fixing plate 5 and on the inner side of the disassembly fixing plate 6, and the clamping plate 30 is slidably clamped in the corresponding sliding grooves 51, and a pin hole 62 is opened on the mounting plate 61, and a pin hole 62 is also opened at the corresponding position of the U-shaped fixing plate 5, and the inner clamping plate 62 of the pin hole 62 A fixed pin 7 is provided, a pull ring is fixedly installed on the top of the fixed pin 7, and a soft rod 71 is clamped on the bottom of the fixed pin 7. The soft rod 71 can prevent the fixed pin 7 from falling off due to bumps during the driving of the car, and the soft rod 71 will bend when subjected to a certain force, so that the fixed pin 7 can be taken out. A plurality of evenly distributed supporting cylinders 41 are fixedly installed inside the cover plate top plate 4. The supporting cylinders 41 make the strength of the cover plate top plate 4 higher, increasing 3. The protection of the battery, a plurality of screws are installed on the U-shaped fixing plate 5, and the screws are threadedly connected to the external mounting frame, and a plurality of evenly distributed card blocks 52 are fixedly installed on the top of the sliding groove 51, and a disassembly groove 53 is formed between the plurality of card blocks 52, and the width of the disassembly groove 53 is equal to the width of the card plate 30.

[0028] When the battery fails and burns, the fixing pin 7 is pulled out with force, and then the fixing plate 6 is removed and the side plate 3 of the cover plate is slid. At this time, the fixing plate 30 will slide out of the sliding groove 51 through the removal groove 53, and the side plate 3 of the cover plate can be quickly removed. Even without tools such as wrenches, the side plate 3 of the cover plate can be quickly removed. When repairing the traditional cover plate, it is cumbersome to remove all the screws on the cover plate before repairing it, which makes the workers spend time on disassembly. Therefore, by setting the disassembly fixing plate, when the battery fails and needs to be repaired, the side plate of the cover plate can be quickly removed, and then the cover plate cover plate can be removed to repair the battery. Even without tools, the cover plate can be quickly removed, which speeds up the repair speed. The cushioning material filled inside the cover plate makes the overall weight lighter and the disassembly easier, making the maintenance of new energy vehicles more convenient.
