In the embodiment of the present disclosure, the battery case 103 is used to house battery modules, and in particular, the battery case 103 of the embodiment of the present disclosure is configured to house split type battery modules, that is, the first battery module 102 and the second battery module 104 in fig. 1, which are connected in series and supply power together to new energy vehicles such as electric automobiles and electric motorcycles. In the embodiment of the disclosure, the first battery module 102 and the second battery module 104 are separated by a novel heat insulating material such as mica, so that only half of the batteries can be burned out during puncture combustion, and the driving safety is improved.
In addition, the battery case 103 may be provided in a case structure, for example, and both sides thereof are opened so that the first and second battery modules 102 and 104 are disposed inside the case-type battery case 103 from the side at the time of installation, and after the first and second battery modules 102 and 104 are disposed inside the battery case 103, the first and second battery side plates 101 and 105 may be respectively mounted on both sides of the battery case 103 so as to mount and fix the first and second battery modules 102 and 104 inside the battery case 103.
Next, the mechanisms of the respective components of the CTC power battery integrated chassis 100 are specifically described with reference to the drawings.
First, referring to fig. 2, a battery case 103 of an embodiment of the present disclosure is described, the battery case 103 of an embodiment of the present disclosure includes a case 201, which may be a rectangular parallelepiped-like structure integrally cast with an aluminum alloy; a connection structure 202 for connecting the tank 201 with other parts of the new energy vehicle, it should be understood that although only one connection structure 202 is shown in fig. 2, two or more connection structures may be included; reinforcing ribs 203 for reinforcing the strength of the case 201; the hollowed-out part 204 is a hole, a groove and other structures on the box 201, and is used for reducing the weight of the box 201.

In the embodiment of the present disclosure, the battery case 103 is partitioned into a first space and a second space by a heat insulating plate 301 (see fig. 3) described later, and the first space and the second space are used to accommodate the split first battery module 102 and second battery module 104, respectively. In the embodiment of the present disclosure, the heat insulating plate 301 may be disposed, for example, at the very center portion of the battery case 103 and along the advancing direction of the new energy vehicle, in which case the split first and second battery modules 102 and 104 are put into the battery case 103 from both sides of the battery case 103 and are insulated using the heat insulating plate 301, and the outside is sealed with the first and second battery side plates 101 and 105, which will be described later in detail.
As described above, the heat shield 301 is used to isolate the battery case 103 into the first space and the second space, so that only half of the battery modules are burned when the battery modules are burned, and the battery modules are sealed by the first battery side plate 101 and the second battery side plate 105 on both sides, so that foreign matters such as dust, muddy water and the like can be prevented from entering the battery modules, and the service life of the battery can be prolonged.
In addition, as shown in fig. 3, the heat shield 301 in the embodiment of the present disclosure includes a heat shield frame 3011, and the periphery of the heat shield frame 3011 may be fixedly connected to the battery case 103.
In addition, the heat shield 301 may further include connectors 3012, 3013, 3014 for connecting the entire CTC power battery integrated chassis with other parts of the new energy vehicle, in the case of the new energy vehicle being an electric motorcycle in the disclosed embodiment, the first connector 3012 is located at the top of the battery box 103 after being mounted in place and for connecting with a driver riding bracket; the second connector 3014 is located at the front side of the battery box 103 and is used for connecting with the whole vehicle steering system; the third connector 3013 is located at the rear side of the battery compartment 103 and is adapted to connect to a rear swing arm.
In addition, the first connecting piece 3012 and the driver riding bracket can be connected by adopting a screw and a nut, and the second connecting piece 3014 and the whole vehicle steering system can be connected by adopting a shaft; and the third link 3013 and the rear rocker arm may also be connected by a shaft.
In the disclosed embodiment, the heat shield 301 is integrally cast, that is, the heat shield 301 includes a first connector 3012, a second connector 3014, and a third connector 3013 extending beyond the housing of the battery case 103, wherein the first connector is located at the top of the battery case 103, the second connector 3014 is located at the front side of the battery case 103, and the third connector 3013 is located at the rear side of the battery case 103.
As shown in fig. 3, in the embodiment of the present disclosure, the second and third connection members 3014 and 3013 are connected by an extension, and the extension extends through the heat insulation board 301 and divides the heat insulation board 301 into a first region and a second region, wherein the first and second regions are filled with a heat insulation material.
That is, unlike the first connector 3012, the second connector 3014 and the third connector 3013 are not connected to one side of the heat shield frame 3011, but extend through the heat shield 301 via an extension, and the bottom of the extension (the side near the third connector 3013) is fixedly connected to one side of the heat shield frame 3011, and the extension thereof is also connected to the other side of the heat shield frame 3011 by a screw, so that the strength of the second connector 3014 and the third connector 3013 can be greatly improved, because the second connector 3014 is connected to the steering system and the third connector 3013 is connected to the rear swing arm in a state of being mounted in place, and thus by providing the second connector 3014 and the third connector 3013 to be connected via an extension extending through the heat shield 301 and being connected to a plurality of sides of the heat shield frame 3011, the strength thereof can be enhanced.
In this case, the extension extends through the heat shield 301 and divides the heat shield 301 into a first region and a second region, wherein the first and second regions are filled with a heat shield material, such as mica boards or the like. In addition, the heat shield 301 may also include a layer of heat shield material 3015, the layer of heat shield material 3015 may be, for example, a mica board, and may also be other heat shield material, and secured to the heat shield frame 3011 by screws or the like. Although in the above description, the heat shield 301 is provided with a mica heat shield material in between, it should be understood that other heat shields may be employed.
In addition, in the embodiment of the present disclosure, a guide structure 3016, which is a rectangular structure including a chamfer, may be further provided at the heat shield 301, wherein the chamfer structure is capable of guiding the battery module to be mounted in place along the chamfer structure. After the battery module is mounted in place, the battery module may be fastened to the heat insulation plate 301 via the mounting posts 3017 by screws or the like.
In a specific implementation manner, the chamfer is set to be of a three-section structure, the slope K1 of the first section is smaller, the slope K2 of the second section is larger, and the slope K3 of the third section is smaller, so that when the battery module is installed, the part of the first section, which is smaller in slope K1, is contacted first to prevent the battery module from being knocked, then the battery module is quickly fixed around a preset position through the second section, which is larger in slope K2, and finally the battery module is fixed in place through the third section, which is smaller in slope K3. Preferably, K2> K3> K1 is required so that the best positioning effect can be achieved because setting K3 to be larger than K1 can prevent the third-stage slope K3 from being too small, resulting in easy sliding of the battery module.
In the above, the arrangement of the battery case 103 and the heat insulating plate 301 is described, and next, with reference to fig. 4 and 5, the structures of the first battery side plate 101 and the second battery side plate 105 are described, wherein fig. 4 is the outside of the battery side plate, and fig. 5 is the inside of the battery side plate. It should be understood that the structures of the first battery side plate 101 and the second battery side plate 105 are symmetrical with respect to the battery case 103, and in the following description, the first battery side plate 101 is described as an example.
As shown in fig. 4 and 5, the first battery side plate 101 of the embodiment of the present disclosure includes a heat sink 1011, a seal ring 1012, a thermally conductive silicone 1013, and a mounting portion 1014.
The heat sink 1011 is provided outside the first battery side plate 101, and may have a plate-like structure in shape, and the heat sink 1011 is provided in a direction consistent with the moving direction, so that air flows along both sides of the heat sink 1011 when a new energy vehicle such as an electric motorcycle moves, and heat can be more removed.
In addition, the thermally conductive silica gel 1013 is provided inside the first battery side plate 101, and the direction of the thermally conductive silica gel 1013 is set to coincide with the direction of the heat radiating fins 1011. Specifically, the heat conductive silica gel 1013 may be arranged in a rectangular shape with intervals, and the long side direction of the rectangle is consistent with the direction of the heat dissipation sheet 1011, so that the overlapping area of the heat conductive silica gel 1013 and the root of the heat dissipation sheet 1011 is larger, and heat can be better taken away. It should be appreciated that in embodiments of the present disclosure, thermally conductive materials other than thermally conductive silicone 1013 may be employed, such as copper, silver, and the like.
In addition, in order to prevent the battery module from being contaminated by dust, muddy water, and the like, the inner side surfaces of the first battery side plate 101 and the second battery side plate 105 further include sealing grooves, and sealing rings 102 are provided in the sealing grooves, so that the battery module can be sealed together with the battery case 103.
As shown, the battery side plate of the embodiment of the present disclosure may be connected to the battery case 103, for example, by the mounting portions 1014 at four corners.
