The inner diameter of the bus passages 121 of the plurality of bus plates 120 may be the same size.

With continued reference to fig. 5-8, each bus plate 120 is provided with a plurality of bus channels 121 spaced apart from each other. The bus duct 121 extends in the second direction D2. The bus duct 121 penetrates the bus plate 120 in the second direction D2. In this way, a plurality of bus ports 191 are formed at the end of the bus plate 120 in the second direction D2. The bus ports 191 include a first bus port at one end of the bus plate 120 in the second direction D2, and a second bus port at the other end of the bus plate 120 in the second direction D2. The plurality of first bus ports and the plurality of second bus ports correspond to one another. The plurality of first bus ports and the plurality of bus channels 121 correspond one to one. The correspondingly arranged first and second confluence ports are both communicated with the same confluence channel 121. The bus channel 121 is connected to the corresponding first bus port. Therefore, the bus bar 120 has a simple structure and is convenient to process.

Preferably, the guide passage 131 extends in the first direction D1. The guide passage 131 penetrates the guide member 130 to form a guide port 132 at an end of the guide member 130 in the first direction D1. The battery pack tray also includes a sealing plug 140. A sealing plug 140 is connected to the end of the flow guide 130 for plugging the flow guide port 132 to seal the flow guide port 132 and prevent fluid leakage at the flow guide port 132. Therefore, the flow guide member 130 has a simple structure and is convenient to process.

An end surface of the flow guide 130 in the second direction D2 is attached to an end surface of the bus bar 120 in the second direction D2. Therefore, the structure of the battery pack chassis is simple.

As shown in fig. 8, the guide passage 131 of the first guide member communicates with the outlet passage 193. The guide passage 131 of the second guide member communicates with the inlet passage 192. The medium may be introduced into the third manifold plate 129 through the inlet port 125, and the medium enters the manifold channel 121 of the manifold plate 120 through the flow guide channel 131 of one flow guide member 130 (second flow guide member) from the third manifold plate 129 in a direction shown by a dotted arrow in fig. 8, then flows into the flow guide channel 131 of another flow guide member 130 (second flow guide member), and finally flows out of the third manifold plate 129 from the outlet port 126 after flowing into the outlet channel 193 of the third manifold plate 129. In this process, the battery pack chassis can regulate the temperature of the battery.

It should be noted that the first direction D1 and the second direction D2 are perpendicular to the height direction D3 of the battery pack. The height direction D3 of the battery pack is parallel to the height direction of the bus bar 120.

As shown in fig. 4 to 8, an end surface of the flow guide 130 in the second direction D2 is connected to an end surface of the bus bar 120 in the second direction D2 by adhesive bonding. Thereby, leakage of liquid at the connection of the flow guide 130 and the bus plate 120 may be prevented.

The guide port 133 communicates to the guide passage 131. When the flow guide member 130 is connected to the bus bar 120, the flow guide port 133 is communicated with the corresponding bus port 191. The inner diameter of the diversion opening 133 can be sized as desired to accommodate the battery assembly 170 placed thereon. For example, if the heat generation amount of the battery assembly 170 placed at a certain position of the bus bar 120 is large, the inner diameter of the diversion opening 133 communicated with the bus duct 121 at the certain position may be increased in size to increase the temperature regulation performance at the certain position.

The utility model also provides a battery package. As shown in fig. 1 to 4, the battery pack is used for a vehicle. The chassis of the vehicle includes a chassis end beam 150. The battery pack includes a battery pack side beam 110 and the aforementioned battery pack chassis.

In this embodiment, the battery pack includes the aforementioned battery pack chassis, and the battery pack chassis can be used to adjust the temperature; in addition, the battery pack chassis is adapted to be coupled to the battery pack side rail 110 such that the battery assembly 170 of the battery pack can be placed on the battery pack chassis such that the battery pack chassis supports the battery assembly 170; therefore, the battery pack chassis can adjust the temperature and also can be used as a stressed structural part of the battery pack, the stressed structural part and the temperature adjusting part are integrated into a whole, and the battery pack has the advantages of small number of parts, light weight, simple structure and low cost; in addition, the number of parts of the battery pack is small, so that the weight of the battery pack is small, and the battery pack is easy to install.

Preferably, as shown in fig. 4, the bottom end of the pack side member 110 is extended and projected toward the center of the battery pack in the second direction D2 to constitute a bottom bracket portion 111. The bus plate 120 and the guide member 130 are overlapped to the bottom bracket portion 111. This simplifies the connection between the battery pack chassis and the battery pack side member 110. The battery pack chassis and the battery pack side beam 110 do not need to be connected in a welding mode, and the battery pack is convenient to install.

With continued reference to fig. 4, a portion of the battery pack side member 110 extends and projects toward the center of the battery pack in the second direction D2 to form a barrier portion 112. The blocking wall part 112 is located above the bottom support part 111 in the height direction D3 of the battery pack, and is spaced apart from the bottom support part 111 by a support plate. The manifold plate 120 and the flow guides 130 are located within the pallet spacing. The baffle portion 112 is attached to the surface of the manifold plate 120 and the deflector 130 away from the shoe portion 111. In the second direction D2, the size of the bottom bracket portion 111 and the size of the blocking wall portion 112 are smaller than the size of the battery pack chassis. In this way, the battery pack chassis is coupled to the battery pack side beam 110. Accordingly, the battery pack chassis and the battery pack side member 110 are firmly connected, thereby improving reliability and safety of the battery pack.

Further preferably, the connection surface between the battery pack chassis and the battery pack side member 110 is provided with glue. This can further increase the connection strength between the battery pack chassis and the battery pack side member 110. In addition, liquid leakage in the battery pack chassis can be further avoided.

As shown in fig. 1 to 3, the battery pack further includes a battery pack end beam 160. The length direction of the battery pack end beam 160 extends in the second direction D2. The end of the pack end beam 160 is connected to the end of the pack side beam 110 to constitute a circumferentially closed ring structure. The battery pack end beam 160 is adapted to be removably coupled to the chassis end beam 150. Therefore, the battery pack is convenient to disassemble and assemble. In addition, the battery pack is fixedly coupled with the whole vehicle chassis, so that the strength of the whole vehicle chassis is ensured, and the stability and the reliability of the battery pack are also ensured.

The upper end of the battery pack end beam 160 extends and protrudes away from the center of the battery pack in the first direction D1 to constitute an end beam upper plate 161. The end rail upper plate 161 is adapted to be lapped to the chassis end rail 150. The end rail upper plate 161 may be removably attached to the chassis end rail 150 by fasteners (e.g., bolts). Thereby facilitating connection of the battery pack to the chassis end beam 150.

The lower end of the battery pack end beam 160 extends and protrudes away from the center of the battery pack in the first direction D1 to constitute an end beam lower plate 162. An end beam space is present between the end beam lower plate 162 and the end beam upper plate 161 in the height direction D3 of the battery pack. The chassis end beams 150 may be disposed within the end beam spaces. The end beam lower plate 162 may be removably attached to the chassis end beam 150 by fasteners (e.g., bolts). In this way, the end beam lower plate 162 supports the chassis end beam 150. Thus, the connection of the chassis end beam 150 and the battery pack end beam 160 is secure.

With continued reference to fig. 1 to 3, a detachment notch 163 is disposed at a substantially middle position of the end beam upper plate 161 along the second direction D2. The detachment notch 163 penetrates the end beam upper plate 161 in the height direction D3 of the battery pack. Thus, if it is desired to remove the battery pack, the fasteners connecting the chassis end beams 150 and 150 may be removed, the structure securing the later battery deck portion 180 to the chassis deck and the structure securing the battery pack side rail 110 to the chassis side rail may be removed, and then the battery pack may be moved in the second direction D2 such that the removal notch 163 is moved to a certain chassis end beam 150; the battery pack is then moved downwardly so that the chassis end beam 150 moves over the end beam upper plate 161. At this point, the battery pack is positioned below the chassis end beam 150, completing the removal of the battery pack. Therefore, the space of the chassis of the whole vehicle is skillfully utilized, and the battery pack can be simply and conveniently detached from the chassis by detaching the notch.

It will be appreciated that in embodiments not shown, the end beam lower plate may also be provided with a removal notch. At this time, if the battery pack needs to be disassembled, the fastener connecting the chassis end beam and the chassis end beam can be disassembled, the structure for fixing the later battery cover plate part to the chassis cover plate and the structure for fixing the side beam of the battery pack to the side beam of the chassis are disassembled, and then the battery pack is moved along the second direction D2, so that the disassembling notch is moved to a certain chassis end beam; the battery pack is then moved upwardly so that the chassis end beam moves below the lower plate of the end beam. At the moment, the battery pack is positioned above the end beam of the chassis, and the battery pack is disassembled.

As shown in fig. 3, the battery pack further includes a battery assembly 170. The battery assembly 170 is located in the area enclosed by the battery pack end beam 160 and the battery pack side beam 110. The battery assembly 170 is strapped to the battery pack chassis.
