Description

Technical Field

[0001] This invention belongs to the field of vehicle battery swapping, specifically relating to an electrical box module that facilitates battery maintenance and replacement. Background Technology

[0002] In the existing technology, the battery box of heavy truck adopts an integrated design. When it is necessary to replace the battery pack inside the box, the cooling system and battery management system on the upper part of the box must be removed before the battery pack can be taken out. This is inconvenient for battery pack replacement and maintenance. When replacing the battery pack, the entire box usually needs to be transported to the repair shop, which greatly increases the transportation cost of battery pack replacement. The battery packs are separated by partitions, making it difficult for the heat generated by the battery pack inside the box to be dissipated, which reduces the cooling and heat dissipation effect of the battery pack itself and thus affects the normal performance of the battery pack.

[0015] According to one or more embodiments of the present invention, the mounting box, base and housing can be disassembled separately, which facilitates the individual maintenance of different functional areas. The battery pack is removed by clamping the fixing frame through the existing clamping mechanism, avoiding the direct clamping of the battery pack by the clamping mechanism and causing damage to the battery pack. When the battery pack is removed, the first fixing plate moves on the rotating sleeve, and the first fixing plate drives the rotating sleeve to rotate on the fixing rod. At the same time, the communication plug is pulled out from the communication port and the liquid guide tube is pulled out from the first connecting tube. Thus, the battery pack can be quickly removed for replacement or maintenance without disassembling any other parts.

[0016] Coolant is introduced into the cooling pipe through the second connecting pipe, and then cools the outside of the battery pack through the heat insulation box. The fan blows the cold air in the heat insulation box out through the air guide channel, and guides it to the front and rear of the battery pack through the arc-shaped guide plate. This allows the hot air on the front and rear of the battery pack to be discharged through the heat dissipation vents and the ventilation openings on the closed door, thereby further cooling the battery pack and ensuring that the battery pack is at the optimal temperature to fully utilize its performance. This avoids the problem that existing battery boxes only rely on the battery pack's own cooling mechanism for heat dissipation, while the heat in the battery box cannot be discharged, affecting the performance of the battery pack. At the same time, it can reduce the amount of external dust entering the casing through the heat dissipation vents and the ventilation openings on the closed door, playing a certain role in dust prevention.

[0017] When the mini vacuum cleaner is activated, it collects the blown-off dust into the mini vacuum cleaner through the suction tube, thus cleaning the corresponding area on the inner wall of the casing at the same time as removing the battery pack, preventing dust accumulation inside the casing from affecting the normal operation of the battery pack.

[0057] When the vehicle is in motion, the coolant in the cooling system is introduced into the conduit 201 through the outlet pipe 001, and then into a guide pipe 320 on the battery pack 303 through the first connecting pipe 202, thereby circulating the coolant in the cooling mechanism of the battery pack 303 to cool it down. The coolant is then led out through another guide pipe 320 on the battery pack 303 to the first connecting pipe 202 on another conduit 201, and then back into the cooling system inside the mounting box 3 through the other first connecting pipe 202. The guide pipe 320 and the first connecting pipe 202 are connected by a plug-in joint, allowing each battery pack 303 to be removed and replaced individually without disassembling the entire cooling system. Simultaneously, the coolant is introduced into the cooling pipe 414 through the second connecting pipe 203, and then into the heat insulation box 401 to cool the exterior of the battery pack 303. The cooling pipe 414 cools the air inside the heat insulation box 401. The fan 415 starts and blows the cold air inside the heat insulation box 401 out through the air guide 012. The air is then guided to the front and rear of the battery pack 303 through the arc-shaped guide plate 404. The hot air on the front and rear of the battery pack 303 is then discharged through the heat dissipation port 003 and the ventilation port on the closed door 101, thereby further cooling the battery pack 303 and ensuring that the battery pack 303 is at the optimal temperature. This fully utilizes the performance of the battery pack 303 and avoids the problem that the existing electrical box only dissipates heat through the cooling mechanism of the battery pack 303 itself, and the heat in the electrical box cannot be discharged, which affects the performance of the battery pack 303. At the same time, it can reduce the amount of external dust entering the housing 2 through the heat dissipation port 003 and the ventilation port on the closed door 101, which plays a certain role in dust prevention.

[0058] Because the existing battery box module adopts an integrated design, when the battery pack 303 inside the battery box needs to be replaced, the cooling system and battery management system on the upper layer of the battery box must be removed before the battery pack 303 can be taken out, which is inconvenient for battery pack 303 replacement and maintenance. When the vehicle is in motion, the rotating sleeve 302 is limited by the second limit rod 316, and the top block 104 abuts against the rectangular block 319 to prevent the first fixing plate 304 from moving, thereby ensuring the stability of the battery pack 303 during vehicle operation. The mounting box 3, base 1 and shell 2 can all be disassembled separately, which facilitates individual maintenance of different functional areas. When the battery pack 303 needs to be replaced, the smart lock 102 on the closed door 101 is opened. 02 When the electrical box module is in normal use, it serves to fix the closed door 101 and prevent theft. Then, the closed door 101 is removed from the side of the housing 2, so that the positioning rod 103 is pulled out from the positioning hole 008, and the top block 104 is pulled out from the rectangular through slot of the first fixing plate 304, thus no longer limiting the rectangular block 319. Before this, the elastic telescopic rod 314 and the second return spring 317 are in a compressed state. At this time, the elastic telescopic rod 314 releases its elastic force, so that the second fixing plate 313 drives the rectangular block 319 to slide in the first fixing plate 304, so that the first wedge block 315 separates from the second wedge block 318. Then, the second return spring 317 releases its elastic force, so that the second limiting rod 316 is in the first fixing plate 304. Sliding causes the second limiting rod 316 to separate from the rotating sleeve 302, allowing the battery pack 303 to be removed. At this time, the first limiting rod 310 and the round rod 311 are still located in the insertion hole 010 and the round groove 011, the first return spring 312 is in a compressed state, the round rod 311 is not directly aligned with the insertion hole 010, and the round rod 311 abuts against the inner wall of the round groove 011, thereby causing the fixing bracket 305 to lock and limit the battery pack 303, preventing the battery pack 303 from sliding directly out of the housing 2 after the closing door 101 is opened. This provides a double safety function when the vehicle is in motion, making it easy to remove the battery pack 303 while ensuring the stability of the battery pack 303 during operation. Then, a hexagonal screw is inserted into the hexagonal screw on the first limiting rod 310. Inside the screw hole, rotate the hexagonal screw to make the first limiting rod 310 drive the round rod 311 to rotate, so that the round rod 311 is aligned with the socket 010. Then, through the existing clamping mechanism, clamp the fixing frame 305 and take out the battery pack 303. This avoids the clamping mechanism directly clamping the battery pack 303 and causing damage to the battery pack 303. When the battery pack 303 is taken out, it drives the first fixing plate 304 to move on the rotating sleeve 302. The first fixing plate 304 drives the rotating sleeve 302 to rotate on the fixing rod 301. At the same time, the communication plug 009 is pulled out from the communication socket 004 and the liquid guide tube 320 is pulled out from the first connecting tube 202. Thus, the battery pack 303 can be quickly taken out for replacement or maintenance without disassembling any other parts.

[0059] As the battery pack 303 is removed, the electric push rod 408 retracts, causing the fourth fixing plate 409 to move the trapezoidal block 410, preventing the trapezoidal block 410 from pressing against the third wedge block 411. This causes the third return spring 413 to release its elasticity, causing the third fixing plate 407 to move the third limiting rod 412 and the second connecting rod 406, allowing the third limiting rod 412 to be pulled out of the limiting hole 007. This facilitates the removal of the heat dissipation assembly if maintenance is required. Simultaneously, the second connecting rod 406 moves the first connecting rod 405, the T-shaped slider 403, and the arc-shaped guide plate 404, causing the arc-shaped guide plate 404 to move towards the center of the heat insulation box 401. The arc-shaped guide plate 404 moves to the other side of the air guide channel 012. At this time, the air blown out through the air guide channel 012 is guided by the arc-shaped guide plate 404 to the inner wall of the housing 2, blowing off the dust on the inner wall of the housing 2. At the same time, the micro air pump 307 starts and sprays air through the jet pipe 308. The air is guided through the arc-shaped guide plate 404 to the inner wall of the housing 2, enhancing the cleaning effect on the dust on the inner wall of the housing 2. At the same time, the micro vacuum cleaner 306 starts and collects the blown-off dust into the micro vacuum cleaner 306 through the suction pipe 309. This achieves cleaning of the corresponding position on the inner wall of the housing 2 at the same time as removing the battery pack 303, preventing the accumulation of dust in the housing 2 from affecting the normal operation of the battery pack 303.
