[0028] In the present embodiment, the current heavy truck battery box is usually composed of a plurality of battery boxes and an external frame as a whole, and is usually located in the external frame and stacked for storage. However, most of the battery boxes use a whole flat plate as a bottom plate, resulting in weak strength of the battery box itself, so that the structural strength design is given to the external frame. However, the external frame is a sheet metal welding part, and the tolerance accuracy is insufficient, so that the battery box with insufficient strength often deforms with the deformation of the external frame. Therefore, in order to solve the above problems, the utility model provides a fusion battery box.

[0029] As shown in Figure 1 , Figure 2 , a fusion battery box can include a box assembly 01 and a battery assembly 02.

[0030] As shown in Figure 1 , Figure 3 ,Figure 4 As shown, the box assembly 01 can include a first plate 11, a second plate 12, a third plate 13 and a top cover 14. The first plate 11 can include a front plate 111, a front beam 112. The second plate 12 can include a rear plate 121, a rear beam 122. The third plate 13 can include a bottom plate 131, a middle beam 132, a first side beam 133, a second side beam 134. One side of the bottom plate 131 can be detachably connected or fixedly connected with the front plate 111. The rear plate 121 can be detachably connected or fixedly connected with the bottom plate 131 away from the side of the front plate 111. The front plate 111 and the rear plate 121 can extend towards the same side away from the bottom plate 131. The side of the front plate 111 close to the rear plate 121 can be detachably connected or fixedly connected with the front beam 112. The side of the rear plate 121 close to the front plate 111 can be detachably connected or fixedly connected with the rear beam 122. The middle beam 132 can be detachably connected or fixedly connected with the bottom plate 131. The front beam 112 can be detachably connected or fixedly connected with the bottom plate 131. The rear beam 122 can be detachably connected or fixedly connected with the bottom plate 131. The first side beam 133 can be detachably connected or fixedly connected with the bottom plate 131. The second side beam 134 can be detachably connected or fixedly connected with the bottom plate 131. One end of the first side beam 133 can be detachably connected or fixedly connected with one end of the front beam 112, and the other end can be detachably connected or fixedly connected with one end of the rear beam 122. One end of the second side beam 134 can be detachably connected or fixedly connected with the side of the front beam 112 away from the first side beam 133, and the other end can be detachably connected or fixedly connected with the side of the rear beam 122 away from the first side beam 133. One end of the first side beam 133 can be detachably connected or fixedly connected with one end of the front plate 111, and the other end can be detachably connected or fixedly connected with one end of the rear plate 121.

One end of the middle beam 132 can be detachably connected or fixedly connected with the first side beam 133, and the other end can be detachably connected or fixedly connected with the second side beam 134. The middle beam 132 can be located at the middle position of the bottom plate 131. The front plate 111, the rear plate 121, the bottom plate 131 and the top cover 14 can form a containing chamber. The front beam 112, the middle beam 132, the first side beam 133, the second side beam 134 and the rear beam 122 can be located in the containing chamber. In this way, the box assembly 01 is provided with the front beam 112, the rear beam 122, the middle beam 132, the first side beam 133 and the second side beam 134, so that the components of the box assembly 01 are connected with each other, and most of the connection positions are located at the connection corners, thereby increasing the strength of the box assembly 01. When the external frame of the containing hybrid battery box is deformed, the hybrid battery box can still ensure the normal operation of the battery assembly 02 by relying on its own strength, thereby avoiding the safety hazard caused by the deformation of the containing hybrid battery box.

[0031] As shown in Figure 2 , the battery assembly 02 can include a battery unit 21. The battery unit 21 can be detachably connected with the box assembly 01. The battery unit 21 can be located in the accommodation chamber. The battery unit 21 can store electric energy, and when an external electric device needs to use electricity, the battery unit 21 can provide electric energy for the electric device.

[0032] In the embodiment, as shown in Figure 3 , the third plate 13 can further include a plurality of fixing holes 135. Part of the bottom plate 131 can extend to the outer peripheral side of the accommodation chamber. The plurality of fixing holes 135 can pass through the bottom plate 131. The plurality of fixing holes 135 can be arranged at intervals along the peripheral side of the bottom plate 131. The plurality of fixing holes 135 can be located outside the accommodation chamber. At present, the fixing holes 135 are usually designed at the bottom center position of the bottom plate 131, and the box assembly 01 is multi-layered, so when the battery assembly 02 is damaged and needs to be repaired or replaced, the other box assemblies 01 below the box assembly 01 to be removed need to be removed to achieve replacement or repair. Therefore, the fixing holes 135 are designed on the peripheral side of the bottom plate 131, so that the single-layer box assembly 01 can be disassembled arbitrarily. Further, the time for repairing or replacing the battery assembly 02 can be reduced.

[0033] In the embodiment, as shown in Figure 3 , the box assembly 01 can further include a first sealing ring 15, a second sealing ring 16, a third sealing ring 17, and a fourth sealing ring 18. The first sealing ring 15 can be detachably connected with the side of the front plate 111 away from the bottom plate 131. The second sealing ring 16 can be detachably connected with the side of the rear plate 121 away from the bottom plate 131. The third sealing ring 17 can be detachably connected with the side of the first side beam 133 away from the second side beam 134. The fourth sealing ring 18 can be detachably connected with the side of the second side beam 134 away from the first side beam 133. The first sealing ring 15 can be located at the joint of the front plate 111 and the top cover 14. The second sealing ring 16 can be located at the joint of the rear plate 121 and the top cover 14. The third sealing ring 17 can be located at the joint of the first side beam 133 and the top cover 14. The first sealing ring 15 can be located at the joint of the second side beam 134 and the top cover 14. In this way, by arranging the first sealing ring 15, the second sealing ring 16, the third sealing ring 17, and the fourth sealing ring 18, the box assembly 01 can be assembled more firmly, and water and external foreign matter can be prevented from entering the accommodation chamber to affect the operation of the battery assembly 02.

[0034] In the embodiment, as shown in Figure 2 , Figure 5As shown, the battery unit 21 can include a battery pack 211, an integrated busbar 212, a first upper cover 213. The integrated busbar 212 can be detachably connected with the battery pack 211 at a side close to the top cover 14. The integrated busbar 212 can be electrically connected with the battery pack 211. The first upper cover 213 can be detachably connected with the integrated busbar 212 at a side close to the top cover 14. The first upper cover 213 can protect the battery pack 211 and the integrated busbar 212 from foreign matter contacting the circuit on the integrated busbar 212, causing short circuit or open circuit of the battery unit 21. The integrated busbar 212 can collect parameters of the battery pack 211, which can include voltage, current, temperature, etc. Thus, according to the parameters, it can be determined whether the battery pack 211 has the risk of out of control.

[0035] In the embodiment, as shown in Figure 5 , the battery assembly 02 can further include a second upper cover 24, shockproof cotton. The second upper cover 24 can be detachably connected with the shockproof cotton. The shockproof cotton can be detachably connected with the first upper cover 213, and the shockproof cotton can be located between the second upper cover 24 and the first upper cover 213. The second upper cover 24 can abut against the top cover 14. Since the battery unit 21 will vibrate during use, for example, during driving of the vehicle. Therefore, the shockproof cotton is added between the first upper cover 213 and the second upper cover 24, so as to reduce the influence of vibration on the battery unit 21, and avoid displacement of the battery unit 21, which can cause damage to the battery unit 21 due to collision.

[0036] In the embodiment, as shown in Figure 3 , Figure 6 , the battery assembly 02 can further include a vertical rod 23. The second upper cover 24 can further include a through hole. One end of the vertical rod 23 can be detachably connected with the middle beam 132, and the other end can abut against the through hole. The outer peripheral wall of the vertical rod 23 can abut against the inner peripheral wall of the through hole. The vertical rod 23 can be located in the accommodation cavity. Since the material of the second upper cover 24 is relatively soft, when the box assembly 01 and the battery unit 21 vibrate, the second upper cover 24 can be displaced. Therefore, the vertical rod 23 penetrates through the second upper cover 24 and abuts against each other, so as to reduce the vibration amplitude of the second upper cover 24, and thus the battery unit 21 can be better protected.

[0037] In the embodiment, as shown in Figure 5 , Figure 7As shown, the fusion battery box can further include a transmission assembly 03. The transmission assembly 03 can include a high-voltage connector 31, a communication connector 32, a first copper bus bar 33, and a second copper bus bar 34. The high-voltage connector 31 can be detachably connected with the front plate 111. The high-voltage connector 31 can be located on the side of the front plate 111 away from the battery assembly 02. The high-voltage connector 31 can achieve safe and efficient transmission of electric energy, ensuring that the battery unit 21 can provide power for the vehicle or other equipment and perform charging operations. The communication connector 32 can be detachably connected with the front plate 111. The communication connector 32 can be located on the side of the front plate 111 away from the battery assembly 02. The communication connector 32 can be electrically connected with the integrated busbar 212. The communication connector 32 can feed back the state of the battery unit 21 to the external battery management system, thereby ensuring the normal operating state of the battery. One end of the first copper bus bar 33 can be electrically connected with the battery assembly 02, and the other end can be electrically connected with the high-voltage connector 31. The battery assembly 02 can include a plurality of battery units 21. The plurality of battery units 21 can be electrically connected through the second copper bus bar 34. Since the first copper bus bar 33 and the second copper bus bar 34 have high conductivity and good heat dissipation performance, etc., the transmission of electric energy can be better guaranteed.

[0038] In the present embodiment, as Figure 5 , Figure 7As shown, the fusion battery box can further include a safety assembly 04. The safety assembly 04 can include an explosion-proof valve 42, a maintenance part 41. The first busbar 33 can include a plurality of first busbars 33. The explosion-proof valve 42 can be detachably connected to the side of the front plate 111 away from the battery assembly 02. The internal chamber of the explosion-proof valve 42 can be in communication with the containing chamber, and the explosion-proof valve 42 in the normal state can make the pressure in the containing chamber the same as the outside. When the battery unit 21 catches fire, the explosion-proof valve 42 can release the pressure in the containing chamber away from the battery unit 21, preventing the battery unit 21 from exploding. The maintenance part 41 can be detachably connected to the side of the front plate 111 away from the battery assembly 02. One end of a first busbar 33 can be detachably and electrically connected to the maintenance part 41, and the other end can be detachably and electrically connected to the high-voltage connector 31. One end of a first busbar 33 can be detachably and electrically connected to the maintenance part 41, and the other end can be detachably and electrically connected to the battery unit 21. The maintenance part 41, the battery unit 21, and the high-voltage connector 31 can be connected in series through the first busbar 33. When the maintenance part 41 is in a closed state, the high-voltage circuit is normally on, and the containing battery box can normally work to provide power for vehicles or other equipment or to charge the battery unit 21. When the maintenance part 41 is in an open state, the high-voltage circuit of the containing battery box is cut off, thereby facilitating the maintenance and inspection of the components in the containing chamber by the technician, i.e., the maintenance part 41 can ensure that the work is performed in a safe environment without high voltage, avoiding the risk of electric shock for the maintenance personnel. The maintenance part 41 also has a fuse, which automatically opens when the transmitted voltage is too large, preventing the fusion battery box from having a safety hazard.

[0039] In this embodiment, as shown in Figure 5 The battery assembly 02 can further include a monitoring part 22. The monitoring part 22 can be detachably connected to the center beam 132. The monitoring part 22 can be electrically connected to the integrated female bus 212. The monitoring part 22 can be electrically connected to the communication connector 32. The monitoring part 22 can monitor the battery unit 21 by collecting the corresponding state of the battery unit 21 through the integrated female bus, ensure the safe operation of the battery unit 21, and feed back the information to the battery management system outside through the communication connector 32.

[0040] In this embodiment, as shown in Figure 7As shown, the fusion battery box can further include a liquid cooling assembly 05. The liquid cooling assembly 05 can include a cooling chamber, a water inlet 51, and a water outlet 52. The cooling chamber can be arranged inside the bottom plate 131. The water inlet 51 can be detachably connected with the bottom plate 131. The water outlet 52 can be detachably connected with the bottom plate 131. The water inlet 51 can be in communication with the cooling chamber. The water outlet 52 can be in communication with the cooling chamber. In this way, the cooling liquid can be fed into the cooling chamber through the water inlet 51. When the cooling liquid is replaced, the cooling liquid can be taken out from the water outlet 52. In this way, the liquid cooling assembly 05 can guarantee the cooling of the battery units 21, prevent the battery from overheating, and prevent safety accidents.

[0041] Those skilled in the art can understand that the above-mentioned embodiments are specific cases for implementing the present disclosure, and in actual application, various changes can be made in form and details without departing from the scope of the present disclosure.
