Description

Technical Field

[0001] This invention belongs to the field of high-voltage distribution box technology, specifically a universal high-voltage distribution box for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source, integrating advanced vehicle power control and drive technologies to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles often use charging stations for charging, and charging stations are equipped with universal high-voltage distribution boxes.

[0003] Patent CN221900377U discloses a sealing structure for a high-voltage power distribution box for new energy vehicles, including a box body and an inlet hole, and further including: a limiting ring disposed inside the inlet hole, the limiting ring having several limiting holes on its surface; a fixing frame fixedly connected to the bottom of the box body, a first fixing plate fixedly connected to the rear of the inner side of the fixing frame; and a torsion plate disposed on the left side of the surface of the fixing frame, a screw fixed to the back of the torsion plate, the other end of the screw being rotatably connected to the rear wall of the fixing frame; this patent, by setting a limiting ring inside the inlet hole, allows multiple cables to pass through the inside of the limiting hole, facilitating cable management, and can also drive the second fixing plate to one side of the first fixing plate, thereby facilitating cable fixation and sealing the inlet hole, thus being suitable for cables of different sizes.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: Distribution boxes typically house multiple electrical components. Since the internal space of a distribution box is fixed, it's difficult to allocate the space efficiently during installation. This can lead to situations where small components are placed in large spaces, resulting in wasted space, or large components are crammed into small spaces, causing installation difficulties and poor heat dissipation due to overcrowding. Secondly, the dense component layout makes it easy to accidentally touch surrounding equipment while maintaining specific components, increasing operational risks and difficulty, and affecting maintenance efficiency. Furthermore, if electrical components inside the distribution box accidentally catch fire due to overheating, and there are no personnel nearby, it's impossible to extinguish the fire in time, potentially causing serious equipment damage or even a safety accident.

[0016] The beneficial effects of this invention are as follows: 1. The universal high-voltage distribution box for new energy vehicles described in this invention utilizes adjustable component installation auxiliary components to achieve a reasonable allocation of the internal installation space of the box. This avoids space waste and prevents poor heat dissipation of components due to overcrowding. Furthermore, since each group of electrical components is isolated from each other, subsequent maintenance personnel are less likely to accidentally touch surrounding equipment, which helps improve maintenance efficiency.

[0017] 2. The universal high-voltage distribution box for new energy vehicles described in this invention utilizes a size-adaptive covered fire extinguishing assembly. When an electrical component inside the box accidentally catches fire, a smoke sensor detects smoke, opening a valve. Dry powder from the fire extinguisher is then sprayed out through a flexible hose and rigid pipe from a conical sleeve, effectively extinguishing the fire inside the box and preventing equipment damage and safety accidents. Furthermore, when a fire breaks out inside the box, a camera also activates simultaneously, aligning the conical sleeve with the area of ​​the fire based on its location. The size of the installation area is determined by using traction blocks to stretch the edge of the conical sleeve into rectangles of varying sizes, ensuring these rectangles fit the dimensions of the installation area. The conical sleeve is then driven close to the partition, covering the installation area. When dry powder is then sprayed from the conical sleeve, it only targets the fire zone, achieving precise fire suppression. This improves fire suppression efficiency and avoids powder waste. Furthermore, the conical sleeve's coverage prevents dry powder from drifting into unburned areas, protecting undisturbed electrical components from damage. Additionally, the fan blades can be rotated during powder spraying to accelerate powder diffusion, resulting in more even coverage of the fire zone and further enhancing the fire suppression effect.

[0018] 3. The universal high-voltage distribution box for new energy vehicles described in this invention utilizes an anti-adhesion component. During the spraying of dry powder through the conical sleeve, a striking rod is used to strike the four sides of the conical sleeve, causing the four sides of the striking rod to vibrate. This causes the dry powder adhering to the inner surface of the conical sleeve to fall off and drift towards the fire area again under the action of airflow, thereby improving the utilization rate of dry powder. At the same time, it also avoids the phenomenon of blockage caused by excessive accumulation of dry powder on the inner surface of the conical sleeve, thus ensuring the continuity and effectiveness of spraying.

One end of the lifting frame 5 is fixedly connected to a motor 8, and the output end of the motor 8 is fixedly connected to one end of the threaded rod 9. One end of the transverse plate 10 is fixedly connected to an electric push rod 11, and the piston end of the electric push rod 11 is fixedly connected to one side of the transverse frame 12.

[0028] One end of the transverse frame 12 is fixedly connected to the mounting frame 19, and both sides of the mounting frame 19 are slidably connected to the adjusting plate 17, and both sides of the adjusting plate 17 are slidably connected to the traction block 37.

[0031] Specifically, in existing technologies, distribution boxes typically require the installation of multiple electrical components. Since the internal space of a distribution box is fixed, it's difficult to allocate the installation space rationally during installation. This can easily lead to situations where small components are placed in large spaces, resulting in wasted space, or large components are crammed into small spaces, causing installation difficulties and poor heat dissipation due to overcrowding. Secondly, the dense component layout makes it easy to accidentally touch surrounding equipment when maintaining specific components, increasing operational risks and difficulty, and affecting maintenance efficiency. Furthermore, if electrical components inside the distribution box accidentally catch fire due to overheating, and there are no personnel nearby, it's impossible to extinguish the fire in time, potentially causing serious equipment damage or even a safety accident.

[0032] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When electrical components need to be installed inside the enclosure 1, according to the space occupied by each group of electrical components, insert the ends of an appropriate number of partitions 6 into the sliding grooves 41 on both sides, and move the partitions 6 up and down to a suitable height, aligning the insertion rods 30 with the insertion holes 29. Then, rotate the double-threaded rod 31 to move the insertion rods 30 and insert them into the corresponding insertion holes 29, thereby fixing the partitions 6. Subsequently, insert the bottom of an appropriate number of partitions 7 into the sliding grooves 42, and insert the insertion rods 32 into the corresponding insertion holes 33 under the action of the springs 35, thus fixing the partitions 7 in place. Furthermore, the upper end of the partitions 7 will abut against the upper partition 6 or the top of the inner cavity of the enclosure 1 under the action of the springs 36. By controlling the number and position of partitions 6 and 7, the interior of the enclosure 1 can be divided into multiple independent component installation areas with controllable space sizes. The size of each installation area matches the overall dimensions of each group of electrical components, thus achieving a rational allocation of the internal installation space of the enclosure 1. This avoids space waste and prevents poor heat dissipation due to overcrowding. Furthermore, because each group of electrical components is isolated, subsequent maintenance personnel are less likely to accidentally touch surrounding equipment, improving maintenance efficiency.

[0033] When the electrical components inside the enclosure 1 catch fire accidentally, the smoke sensor 26 will detect the smoke, and the valve 3 will open. The dry powder inside the fire extinguisher 2 will be sprayed out through the hose 4 and the rigid pipe 16 and then through the conical sleeve 15, thereby extinguishing the fire inside the enclosure 1 and preventing equipment damage and safety accidents.

[0034] While the above methods can extinguish fires inside enclosure 1, the coverage area of ​​the dry powder sprayed through the conical sleeve 15 is fixed. Since enclosure 1 is divided into multiple independent installation zones, if an electrical component in a particular zone catches fire, the dry powder may not cover that component, thus affecting the extinguishing effect. Furthermore, even if the coverage area is expanded by increasing the number of dry powder nozzles, the excessive coverage will cause dry powder to spray onto uncaught installation zones, wasting powder and potentially damaging uncaught electrical components. Therefore, to address this issue, after all electrical components are installed, camera 27 is activated to photograph the interior of enclosure 1, and image analysis technology is used to record the location and size of each installation zone. When an accidental fire occurs inside the housing 1, the camera 27 will also activate simultaneously. Based on the area of ​​the fire, motor 214 will drive threaded rod 213 to rotate, and motor 8 will drive threaded rod 9 to rotate, adjusting the lateral and longitudinal positions of the conical sleeve 15 so that it aligns with the installation area on fire. Furthermore, depending on the size of the installation area, motor 434 will drive bidirectional threaded rod 340 to rotate, adjusting the distance between the two adjusting plates 17. Motor 538 will drive bidirectional threaded rod 239 to rotate, adjusting the distance between the two adjacent traction blocks 37. Thus, the traction blocks 37 will move the edge of the conical sleeve 15 in this manner. Because the conical sleeve 15 has… Because of its elasticity, the conical sleeve 15 can be stretched into rectangles of different sizes using the traction block 37, ensuring that the rectangle matches the size of the installation area. Then, the electric actuator 11 moves the conical sleeve 15 closer to the partition 6 until the edge of the conical sleeve 15 is in contact with the partition 6. At this point, the installation area is covered by the conical sleeve 15. When dry powder is then sprayed from the conical sleeve 15, it only acts on the fire area, achieving precise fire extinguishing. This improves fire extinguishing efficiency and avoids waste of dry powder. Furthermore, due to the coverage of the conical sleeve 15, the dry powder will not drift towards unburned installation areas, preventing damage to unburned electrical components from the spray. Additionally, when the dry powder is sprayed, the motor 24 can drive the fan blades 43 to rotate, which intensifies the diffusion of the dry powder, allowing it to cover the fire area more evenly and further improving the fire extinguishing effect.

[0035] In this embodiment, as Figure 3 and Figure 8 As shown, it also includes anti-adhesion components; The anti-adhesion assembly includes multiple striking rods 18, which are distributed circumferentially and rotatably mounted on the rigid tube 16.

[0036] A transmission ring 21 is slidably connected to one side of the outer wall of the rigid tube 16. Multiple racks 22 are evenly distributed and fixedly connected to one end face of the transmission ring 21 along the circumference. A gear 23 is fixedly connected to one end of the striking rod 18. The gear 23 meshes with the racks 22. An electric push rod 20 is fixedly connected to one side of the outer wall of the rigid tube 16. The piston end of the electric push rod 20 is fixedly connected to one side of the transmission ring 21.

[0037] Specifically, in the above embodiments, although the spraying range of dry powder can be controlled by using the conical sleeve 15, since the conical sleeve 15 is elastic, when the dry powder is sprayed out through the conical sleeve 15, it is inevitable that some dry powder will adhere to the inner surface of the conical sleeve 15. This will not only affect the utilization rate of the dry powder, but may also cause blockage due to excessive accumulation of dry powder on the inner surface of the conical sleeve 15, thereby affecting the spraying effect of the dry powder.

[0038] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: During the spraying of dry powder through the conical sleeve 15, the electric actuator 20 drives the transmission ring 21 to slide back and forth. Under the transmission of gear 23 and rack 22, multiple striking rods 18 can rotate back and forth simultaneously. The striking rods 18 can then strike the four sides of the conical sleeve 15, causing the four sides of the striking rods 18 to vibrate. This causes the dry powder adhering to the inner surface of the conical sleeve 15 to fall off and drift back towards the fire area with the airflow, thereby improving the utilization rate of dry powder. At the same time, it also avoids the phenomenon of clogging caused by excessive accumulation of dry powder on the inner surface of the conical sleeve 15, thus ensuring the continuity and effectiveness of spraying.

[0039] Working principle: When electrical components need to be installed inside the enclosure 1, according to the space occupied by each group of electrical components, insert the ends of an appropriate number of partitions 6 into the sliding grooves 41 on both sides, and move the partitions 6 up and down to a suitable height, aligning the insertion rods 30 with the insertion holes 29. Then, rotate the double-threaded rod 31 to move the insertion rods 30 and insert them into the corresponding insertion holes 29, thereby fixing the partitions 6. Subsequently, insert the bottom of an appropriate number of partitions 7 into the sliding grooves 42, and insert the insertion rods 32 into the corresponding insertion holes 33 under the action of the springs 35, thus fixing the partitions 7. Furthermore, the upper end of the partitions 7 will abut against the upper partition 6 or the top of the inner cavity of the enclosure 1 under the action of the springs 36. By controlling the number and position of partitions 6 and 7, the interior of the enclosure 1 can be divided into multiple independent component installation areas with controllable space sizes. The size of each installation area matches the overall dimensions of each group of electrical components, thus achieving a rational allocation of the internal installation space of the enclosure 1. This avoids space waste and prevents poor heat dissipation due to overcrowding. Furthermore, since each group of electrical components is isolated, subsequent maintenance personnel are less likely to accidentally touch surrounding equipment, improving maintenance efficiency. If an electrical component inside the enclosure 1 accidentally catches fire, the smoke sensor 26 will detect smoke, causing valve 3 to open. The dry powder inside the fire extinguisher 2 will then be sprayed through the hose 4, rigid pipe 16, and finally from the conical sleeve 15, effectively extinguishing the fire inside the enclosure 1 and preventing equipment damage and safety accidents. While the above methods can extinguish fires inside enclosure 1, the coverage area of ​​the dry powder sprayed through the conical sleeve 15 is fixed. Since enclosure 1 is divided into multiple independent installation zones, if an electrical component in a particular zone catches fire, the dry powder may not cover that component, thus affecting the extinguishing effect. Furthermore, even if the coverage area is expanded by increasing the number of dry powder nozzles, the excessive coverage will cause dry powder to spray onto uncaught installation zones, wasting powder and potentially damaging uncaught electrical components. Therefore, to address this issue, after all electrical components are installed, camera 27 is activated to photograph the interior of enclosure 1, and image analysis technology is used to record the location and size of each installation zone.When an accidental fire occurs inside the housing 1, the camera 27 will also activate simultaneously. Based on the area of ​​the fire, motor 214 will drive threaded rod 213 to rotate, and motor 8 will drive threaded rod 9 to rotate, adjusting the lateral and longitudinal positions of the conical sleeve 15 so that it aligns with the installation area on fire. Furthermore, depending on the size of the installation area, motor 434 will drive bidirectional threaded rod 340 to rotate, adjusting the distance between the two adjusting plates 17. Motor 538 will drive bidirectional threaded rod 239 to rotate, adjusting the distance between the two adjacent traction blocks 37. Thus, the traction blocks 37 will move the edge of the conical sleeve 15 in this manner. Because the conical sleeve 15 has… Because of its elasticity, the conical sleeve 15 can be stretched into rectangles of different sizes using the traction block 37, ensuring that the rectangle matches the size of the installation area. Then, the electric actuator 11 moves the conical sleeve 15 closer to the partition 6 until the edge of the conical sleeve 15 is in contact with the partition 6. At this point, the installation area is covered by the conical sleeve 15. When dry powder is then sprayed from the conical sleeve 15, it only acts on the fire area, achieving precise fire extinguishing. This improves fire extinguishing efficiency and avoids waste of dry powder. Furthermore, due to the coverage of the conical sleeve 15, the dry powder will not drift towards unburned installation areas, preventing damage to unburned electrical components from the spray. Additionally, when the dry powder is sprayed, the motor 24 can drive the fan blades 43 to rotate, which intensifies the diffusion of the dry powder, allowing it to cover the fire area more evenly and further improving the fire extinguishing effect. During the spraying of dry powder through the conical sleeve 15, the electric actuator 20 drives the transmission ring 21 to slide back and forth. Under the transmission of gear 23 and rack 22, multiple striking rods 18 can rotate back and forth simultaneously. The striking rods 18 can then strike the four sides of the conical sleeve 15, causing the four sides of the striking rods 18 to vibrate. This causes the dry powder adhering to the inner surface of the conical sleeve 15 to fall off and drift back towards the fire area with the airflow, thereby improving the utilization rate of dry powder. At the same time, it also avoids the phenomenon of clogging caused by excessive accumulation of dry powder on the inner surface of the conical sleeve 15, thus ensuring the continuity and effectiveness of spraying.
