Description

Technical Field

[0001] This invention relates to the field of new energy battery box technology, specifically a heat-insulating and flame-retardant new energy battery box. Background Technology

[0002] New energy battery boxes are one of the core components of new energy equipment such as electric vehicles and energy storage systems. They are mainly responsible for housing, protecting and managing battery packs to ensure their safe and efficient operation.

[0003] Currently, existing new energy battery boxes typically use a circulating water cooling plate below the battery mounting area for heat dissipation and insulation. Some new energy battery boxes used in environments with high temperatures will have heat sinks under the water cooling plate, using a combination of air cooling and water cooling. This setup makes it easy for dust to attract onto the heat sinks due to static electricity during air cooling. If not cleaned in time, it will affect the overall cooling efficiency of the liquid cooling system. Therefore, a new energy battery box is needed to solve this problem. Summary of the Invention

[0004] This invention provides a heat-insulating and flame-retardant new energy battery box, which facilitates the cleaning of heat sinks and enables sustainable heat dissipation through both air and water cooling. It addresses the problem mentioned in the background section where some new energy battery boxes used in high-temperature environments have heat sinks installed under a water-cooling plate, utilizing a combination of air and water cooling. This setup easily leads to dust accumulation on the heat sinks due to static electricity during air cooling, which, if not cleaned promptly, affects the overall liquid cooling system's efficiency. To achieve the above objective, this invention provides the following technical solution: A heat-insulating and flame-retardant new energy battery box, comprising a battery box body and a first sleeve. A second sleeve is slidably connected to the inner wall of the first sleeve. A transmission gear ring is rotatably mounted on the outer wall of the second sleeve.

A guide rod is fixedly connected to the outer wall of the second sleeve, and the guide rod is slidably connected to the inner wall of the spiral groove. A rotating plate is rotatably connected to one end of the second sleeve. A rotating ring is fixedly connected to the outer wall of the rotating plate, and multiple evenly distributed soft brushes are fixedly mounted on the outer wall of the rotating ring.

[0005] Preferably, an electric telescopic rod is fixedly installed on the outer wall of the battery box body, a movable frame is fixedly connected to the output end of the electric telescopic rod, a sliding groove is opened on the outer wall of the movable frame, a guide rod is fixedly connected to the inner wall of the sliding groove, and a sliding block is slidably connected to the outer wall of the guide rod.

[0006] Preferably, a return spring is fixedly connected to the outer wall of the sliding block, and the other end of the return spring is fixedly connected to the inner wall of the slide groove. The first sleeve is fixedly connected to the outer wall of the sliding block.

[0007] Preferably, a rubber turntable is fixedly connected to the outer wall of the third sleeve, and the outer wall of the rubber turntable abuts against the inner wall of the rotating ring.

[0008] Preferably, a supporting base plate is fixedly connected to the inner wall of the battery box body, and the outer wall of the supporting base plate is provided with a bending track groove and a straight track groove, which are interconnected.

[0009] Preferably, the inner wall of the bending trajectory groove is fixedly connected to a first transmission rack and a second transmission rack.

[0010] Preferably, multiple rotating shafts are rotatably mounted on the inner walls of the bending track groove and the straight track groove. One end of each rotating shaft is rotatably connected to a fixed plate. The outer wall of the fixed plate is fixed to the inner wall of the bending track groove. A torsion spring is sleeved on the outer wall of the rotating shaft. One end of the torsion spring is fixedly connected to the outer wall of the fixed plate. The other end of the torsion spring is fixedly connected to a baffle. The baffle is fixedly connected to the outer wall of the rotating shaft. Limiting blocks are also fixedly connected to the inner walls of the bending track groove and the straight track groove. The limiting blocks are configured with an arc-shaped contour.

[0011] Preferably, the transmission gear ring is slidably connected to the inner wall of the bending track groove, a heat dissipation support plate is fixedly installed on the inner wall of the battery box body, a cooling circulation bend is fixedly installed on the inner wall of the heat dissipation support plate, and a coolant inlet and a coolant outlet are fixedly installed on the outer wall of the battery box body, both of which are connected to the cooling circulation bend.

[0012] Preferably, a plurality of heat sinks are fixedly installed on the outer wall of the heat dissipation support plate, and the heat sinks are distributed between the bends of the bending track groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In this invention, the heat on the heat dissipation support plate is transferred to multiple heat sinks arranged below for distribution. The cooling fan transports the heat in the space between the support base plate and the support plate to the outside for discharge, thus completing the heat dissipation of the cooling circulation bend support plate and allowing the coolant in the cooling circulation bend to be recycled. Since the heat sinks are regularly arranged between the bends of the bending track groove, when the transmission gear ring moves, it will move the rotating ring and the soft brush synchronously. Due to the trajectory of the bending track groove, the soft brush can clean the floating dust on each surface of the outer wall of the heat sink.

[0016] 2. In this invention, when the transmission gear ring moves along the inner wall of the curved track groove, the soft brush can clean the outer wall of the heat sink horizontally while simultaneously moving up and down intermittently. This allows the soft brush to clean the gap at the right angle connecting the heat sink and the heat sink support plate, further increasing the coverage of the brushing on the outer wall of the heat sink.

[0017] 3. In this invention, the rotating ring will rotate along the end of the second sleeve with the rotating plate, so that the soft brush will also rotate intermittently during the sliding brushing process on the outer wall of the heat sink, and after rotating for a period of time, it will rotate in the opposite direction, so as to scrape off the old dust that is adhered to the outer wall of the heat sink to different degrees in different rotation directions. The soft brush rotates to further scrape off the old dust that is adhered to the outer wall of the heat sink. Attached Figure Description

[0028] Example 1: This example addresses the issue that some new energy battery boxes used in high-temperature environments have heat sinks 36 installed under the water-cooled plate, utilizing a combination of air and water cooling for heat dissipation. This setup makes it easy for dust to attract onto the heat sinks 36 due to static electricity during air cooling. If not cleaned promptly, this can affect the overall cooling efficiency of the liquid cooling system. Please refer to [link / reference needed]. Figure 1 - Figure 8 A heat-insulating and flame-retardant new energy battery box includes a battery box body 1 and a first sleeve 22. A second sleeve 23 is slidably connected to the inner wall of the first sleeve 22. A transmission gear ring 24 is rotatably installed on the outer wall of the second sleeve 23.

A plurality of evenly distributed soft brushes 31 are fixedly installed on the outer wall of the rotating ring 28.

[0029] An electric telescopic rod 5 is fixedly installed on the outer wall of the battery box body 1. A movable frame 11 is fixedly connected to the output end of the electric telescopic rod 5. A sliding groove 34 is opened on the outer wall of the movable frame 11. A guide rod 32 is fixedly connected to the inner wall of the sliding groove 34. A sliding block 21 is slidably connected to the outer wall of the guide rod 32.

[0030] A return spring 33 is fixedly connected to the outer wall of the sliding block 21. The other end of the return spring 33 is fixedly connected to the inner wall of the slide groove 34. The first sleeve 22 is fixedly connected to the outer wall of the sliding block 21.

[0031] A support base plate 12 is fixedly connected to the inner wall of the battery box body 1. The outer wall of the support base plate 12 is provided with a bending track groove 13 and a straight track groove 16, which are interconnected.

[0032] The inner wall of the bending track groove 13 is fixedly connected to the first transmission rack 14 and the second transmission rack 15.

[0033] Multiple rotating shafts 17 are rotatably mounted on the inner walls of the bending track groove 13 and the straight track groove 16. One end of the rotating shaft 17 is rotatably connected to a fixing plate 35. The outer wall of the fixing plate 35 is fixed to the inner wall of the bending track groove 13. A torsion spring 18 is sleeved on the outer wall of the rotating shaft 17. One end of the torsion spring 18 is fixedly connected to the outer wall of the fixing plate 35. The other end of the torsion spring 18 is fixedly connected to a baffle 19. The baffle 19 is fixedly connected to the outer wall of the rotating shaft 17. Limiting blocks 20 are also fixedly connected to the inner walls of the bending track groove 13 and the straight track groove 16. The limiting blocks 20 are set with an arc-shaped contour.

[0034] The transmission gear ring 24 is slidably connected to the inner wall of the bending track groove 13. A heat dissipation support plate 9 is fixedly installed on the inner wall of the battery box body 1. A cooling circulation bend 4 is fixedly installed on the inner wall of the heat dissipation support plate 9. A coolant inlet 2 and a coolant outlet 3 are fixedly installed on the outer wall of the battery box body 1. Both the coolant inlet 2 and the coolant outlet 3 are connected to the cooling circulation bend 4.

[0035] Multiple heat sinks 36 are fixedly installed on the outer wall of the heat dissipation support plate 9, and the heat sinks 36 are distributed between the bends of the bending track groove 13.

[0036] A heat insulation plate 6 is fixedly connected to the inner wall of the battery box body 1. An installation frame 10 is fixedly installed on the outer wall of the battery box body 1. An air duct 7 is fixedly installed on the outer wall of the battery box body 1. Multiple cooling fans 8 are fixedly installed on the outer wall of the air duct 7. The air duct 7 is connected to the interior of the battery box body 1.

[0037] In this embodiment: When using the new energy battery box, the new energy battery box can be installed in the working position by bolts through multiple mounting frames 10 set on the outside of the battery box body 1. The heat insulation plate 6 divides the space where the batteries are placed inside the battery box body 1 into six equal spaces. The batteries in the six spaces are separated by the heat insulation plate 6, and the heat insulation plate 6 plays a role in heat insulation.

[0038] An external water pump delivers coolant to the coolant inlet 2. After entering the coolant inlet 2, the coolant is delivered to the bent cooling circulation bend 4, which covers the entire battery placement area. As the coolant flows through the bent cooling circulation bend 4, it can carry away the heat dissipated by the battery above through heat exchange. When the coolant reaches the end of the cooling circulation bend 4, it flows out through the coolant outlet 3 at the end of the cooling circulation bend 4 and is then delivered back to the water pump and delivered back to the coolant inlet 2 for circulating cooling.

[0039] During the cooling process of the battery by the heat dissipation support plate 9 and the cooling circulation bend 4, since the heat dissipation support plate 9 is made of brass with good thermal conductivity, the heat on the heat dissipation support plate 9 will be transferred to the multiple heat sinks 36 set below for distribution. Then the cooling fan 8 is started, and the rotation of the multiple cooling fans 8 will transfer the heat in the space between the support base plate 12 and the heat dissipation support plate 9 to the outside for discharge, thus completing the heat dissipation of the cooling circulation bend 4 and the heat dissipation support plate 9. This allows the coolant in the cooling circulation bend 4 to be recycled, preventing the coolant from overheating and being unable to exchange heat.

[0040] After a period of use, the electric telescopic rod 5 is activated. Upon activation, the electric telescopic rod 5 moves the output end's moving frame 11 away from the electric telescopic rod 5. During this movement, the moving frame 11 carries the second sleeve 23 and the transmission gear ring 24, which slide along the inner wall of the bending track groove 13. Due to the bending of the track groove 13, the transmission gear ring 24 is guided along its trajectory. When the transmission gear ring 24 slides to the bend of the bending track groove 13, the electric telescopic rod 5 is activated in the opposite direction, causing the transmission gear ring 24 to move closer to the electric telescopic rod along the bend. The telescopic rod 5 moves in a certain direction to prevent the transmission gear ring 24 from jamming and being unable to move. A baffle 19 is provided in the bending track groove 13. When the transmission gear ring 24 slides against the baffle 19, the baffle 19 rotates the rotating shaft 17. At the same time, the rotation twists the torsion spring 18. When the transmission gear ring 24 passes the baffle 19, the torsion spring 18 twists and resets, and the baffle 19 resets. When the transmission gear ring 24 continues to move, the baffle 19 is blocked by the limiting block 20, so that the transmission gear ring 24 can only move unidirectionally along the track of the bending track groove 13, preventing the transmission gear ring 24 from moving back.

[0041] Since the heat sink 36 is regularly arranged between the bends of the bending track groove 13, when the transmission gear ring 24 moves, it will move the rotating ring 28 and the soft brush 31 synchronously, causing the soft brush 31 to brush the outer wall of the heat sink 36 when it passes through it. Due to the track of the bending track groove 13, the soft brush 31 can brush away the floating dust in all directions on the outer wall of the heat sink 36.

[0042] As the transmission gear ring 24 slides along the inner wall of the bending track groove 13, the movement trajectory of the transmission gear ring 24 will intermittently mesh with the first transmission rack 14 and the second transmission rack 15 on the inner wall of the bending track groove 13. When it meshes with the first transmission rack 14, it causes the transmission gear ring 24 to rotate. The rotation of the transmission gear ring 24 causes the third sleeve 25 to rotate synchronously. When the third sleeve 25 rotates, the guide rod 30 slides in the spiral groove 29 on the outer wall of the third sleeve 25. When the third sleeve 25 rotates, the guide rod 30 causes the second sleeve 23 to be moved upward by the force. At this time, the second sleeve 23 slides upward along the inner wall of the first sleeve 22. The second sleeve 23 carries the rotating plate 27 and the rotating ring 28 to move upward continuously.

[0043] When the transmission gear ring 24 meshes with the second transmission rack 15, the transmission gear ring 24 rotates in the opposite direction, causing the second sleeve 23 to move downward continuously with the rotating plate 27 and the rotating ring 28. In summary, when the transmission gear ring 24 moves along the inner wall of the bent track groove 13, the soft brush 31 can clean the outer wall of the heat sink 36 horizontally while simultaneously brushing the outer wall of the heat sink 36 intermittently up and down. This can cover the right angle where the heat sink 36 and the heat sink support plate 9 are connected, preventing dust accumulation at the right angle and further increasing the degree of cleaning of the outer wall of the heat sink 36.

[0044] Furthermore, when the transmission gear ring 24 slides to the end of the bent track groove 13, it will slide along the track of the bent track groove 13 into the straight track groove 16. A baffle 19 is also provided at the alternating position of the bent track groove 13 and the straight track groove 16. The baffle 19 prevents the transmission gear ring 24 from sliding into the bent track groove 13 after sliding into the straight track groove 16, ensuring that the transmission gear ring 24 can only slide in one direction. It should be noted that after the transmission gear ring 24 slides into the straight track groove 16, it will slide along the track of the bent track groove 13 into the bent track groove 16. During the process of sliding from the beginning to the end within the guide rod 32, the transmission gear ring 24, along with the first sleeve 22 and the sliding block 21, continuously slides and adapts to prevent the position from getting stuck. When the sliding block 21 slides, it compresses and tightens the return spring 33. When the transmission gear ring 24 slides into the straight track groove 16, the return spring 33 instantly resets, carrying the sliding block 21 to slide and reset along the slide groove 34. At this time, the transmission gear ring 24 also slides back into the starting position of the bent track groove 13 along the straight track groove 16, starting a new round of cleaning.

[0045] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 - Figure 8 A rubber turntable 26 is fixedly connected to the outer wall of the third sleeve 25, and the outer wall of the rubber turntable 26 abuts against the inner wall of the rotating ring 28.

[0046] In this embodiment: when the transmission gear ring 24 slides along the bending track groove 13, when the transmission gear ring 24 meshes with the first transmission rack 14 or the second transmission rack 15 and rotates, the rotation of the transmission gear ring 24 will cause the rubber turntable 26 to rotate synchronously. The rotation of the rubber turntable 26 will cause its outer wall to rub against the inner wall of the rotating ring 28. The friction causes the rotating ring 28 to be subjected to rotational force. The rotating ring 28 will then cause the rotating plate 27 to rotate along the end of the second sleeve 23, so that the soft brush 31 will also rotate during the sliding brushing process on the outer wall of the heat sink 36. Due to the arrangement of the first transmission rack 14 and the second transmission rack 15, the soft brush 31 will rotate in the opposite direction after rotating for a period of time. The rotation of the soft brush 31 will further scrape off the adhering dust on the outer wall of the heat sink 36.
