[0032] Hereinafter, the plug-in assembly 10 of the embodiments of the present application is described.

[0033] Please refer to Figure 3 and Figure 4 , Figure 3 is a structural schematic view of an embodiment of the plug-in assembly of the present application, Figure 4 is Figure 3 a structural schematic view of the plug-in assembly shown in FIG. 1, in which the side wall of the base is omitted.

[0034] In an embodiment, the plug-in assembly 10 has a plug-in direction P. The plug-in assembly 10 comprises a base 11 for connecting a body of the vehicle. The plug-in assembly 10 further comprises a plug-in body 12 movably arranged in the base 11, the plug-in body 12 being configured to be able to be plugged with a battery pack 20 of the vehicle along the plug-in direction P. Specifically, the plug-in body 12 can be plugged with an interface assembly 21 of the battery pack 20. The plug-in assembly 10 further comprises a first buffer 13 arranged between the base 11 and the plug-in body 12, the first buffer 13 being configured to be able to buffer the plug-in body 12 along the plug-in direction P. The plug-in assembly 10 further comprises a second buffer 14 arranged between the base 11 and the plug-in body 12, the second buffer 14 being configured to be able to buffer the plug-in body 12 along a direction intersecting the plug-in direction P.

[0035] By the above manner, the first buffer 13 and the second buffer 14 of the embodiment buffer the plug-in body 12 from different directions, which can reduce the risk of damage of the plug-in assembly 10. The vehicle applying the plug-in assembly 10 of the embodiment can adopt the battery replacement scheme. The plug-in assembly 10 of the embodiment is provided with the first buffer 13 and the second buffer 14 to buffer the plug-in body 12 from different directions, which can avoid the damage of the plug-in assembly 10 caused by the relative position deviation of the plug-in assembly 10 and the external impact force in the battery replacement process as far as possible, and avoid the damage of the plug-in assembly 10 caused by the impact force in the road bumping process as far as possible.

[0036] Of course, in other embodiments of the present application, the plug-in assembly 10 can also be applied to vehicles that do not adopt the battery replacement scheme. The battery pack 20 of the vehicle remains plugged with the plug-in assembly 10. The plug-in assembly 10 is provided with the first buffer 13 and the second buffer 14 to buffer the plug-in body 12 from different directions, which can also reduce the risk of damage of the plug-in assembly 10, which is not limited herein.

[0037] In an embodiment, the first buffer 13 can be an elastic element such as a spring. The first buffer 13 is arranged between the base 11 and the plug-in body 12, and the first buffer 13 extends along the plug-in direction P, so that the first buffer 13 can buffer the plug-in body 12 along the plug-in direction P. It should be understood that the extension direction of the first buffer 13 is parallel to the plug-in direction P, or the extension direction of the first buffer 13 has a small angle with the plug-in direction P, for example, the angle is less than 10°, etc.

[0038] Similarly, the second buffer 14 can also be an elastic element such as a spring. The second buffer 14 is arranged between the base 11 and the plug-in body 12, and the second buffer 14 extends along a direction intersecting the plug-in direction P, so that the second buffer 14 can buffer the plug-in body 12 along the direction intersecting the plug-in direction P. It should be understood that the extension direction of the second buffer 14 is perpendicular to the plug-in direction P, or the extension direction of the second buffer 14 is nearly perpendicular to the plug-in direction P, for example, the angle between the extension direction of the second buffer 14 and the plug-in direction P is 80° to 90°, etc.

[0039] In an embodiment, the base 11 is provided with a relief opening 112, and the plug-in body 12 is arranged in the relief opening 112, so that the plug-in body 12 is movably arranged relative to the base 11. The cross-sectional area of the part of the plug-in body 12 at the relief opening 112 is smaller than the opening area of the relief opening 112, so as to allow the plug-in body 12 to move relative to the base 11 along the plug-in direction P and the direction intersecting the plug-in direction P. It should be understood that the cross section of the plug-in body 12 is the cross section of the plug-in body 12 intersecting the plug-in direction P.

[0040] In the above manner, the embodiment enables the plug-in body 12 to move relative to the base 11 along the plug-in direction P and a direction intersecting the plug-in direction P by providing the relief opening 112 in the base 11. When the plug-in body 12 is impacted in the plug-in direction P, the first buffer 13 can buffer the plug-in body 12 along the plug-in direction P. When the plug-in body 12 is impacted in a direction intersecting the plug-in direction P, the second buffer 14 can buffer the plug-in body 12 along the direction intersecting the plug-in direction P. In this way, the risk of damage to the plug-in assembly 10 can be reduced. In particular, the relative position deviation of the plug-in assembly 10 and external impact force during battery replacement can be avoided as much as possible, and the impact force caused by road bumps during driving can be avoided as much as possible.

[0041] Further, the plug-in assembly 10 further comprises a sleeve 15, which is sleeved on the outer periphery of the plug-in body 12 and connected with the base 11. The sleeve 15 can be an elastic body, and is configured to cooperate with the first buffer 13 and the second buffer 14 to buffer the plug-in body 12. With the movement of the plug-in body 12 relative to the base 11, the sleeve 15 can cooperate with the first buffer 13 and the second buffer 14 to buffer the plug-in body 12, further reducing the risk of damage to the plug-in assembly 10.

[0042] Of course, it can be understood that the sleeve 15 is also configured to shield the gap between the plug-in body 12 and the edge of the relief opening 112, which can prevent as much as possible the entry of dirt into the interior of the base 11 through the gap between the plug-in body 12 and the edge of the relief opening 112, and is conducive to ensuring the long-term stable and reliable operation of the plug-in assembly 10, and is conducive to prolonging the service life of the plug-in assembly 10.

[0043] Optionally, the sleeve 15 can be made of rubber, silicone or other elastic materials, which is not limited herein.

[0044] In an embodiment, the interior of the base 11 has a receiving cavity 111 in communication with the relief opening 112, and part of the plug-in body 12, the first buffer 13 and the second buffer 14 are all accommodated in the receiving cavity 111. In the receiving cavity 111, the first buffer 13 is connected with the plug-in body 12 and the base 11 respectively, so that the first buffer 13 can buffer the plug-in body 12 along the plug-in direction P, and the second buffer 14 is connected with the plug-in body 12 and the base 11 respectively, so that the second buffer 14 can buffer the plug-in body 12 along the direction intersecting the plug-in direction P.

[0045] Specifically, the base 11 has an inner top wall 113 arranged opposite to the escape opening 112 in the plugging direction P. The outer side wall of the part of the plug-in body 12 in the accommodating cavity 111 is provided with a connecting portion 121. One end of the first buffer 13 is connected to the connecting portion 121, and the other end is connected to the inner top wall 113. When the plug-in body 12 is impacted by a force in the plugging direction P, the plug-in body 12 is extruded against the first buffer 13 through the connecting portion 121 and the base 11, and the elastic recovery force provided by the first buffer 13 can buffer the plug-in body 12 in the plugging direction P.

[0046] The number of the second buffers 14 is multiple, and each second buffer 14 is distributed along the outer periphery of the plug-in body 12. When the plug-in body 12 is impacted by a force in a direction intersecting the plugging direction P, the elastic recovery force provided by each second buffer 14 cooperates to buffer the impact force in each direction intersecting the plugging direction P.

[0047] For example, please refer to Figure 5 , two first buffers 13 are arranged on one side of the plug-in body 12, and each first buffer 13 is connected to the connecting portion 121 of the plug-in body 12. The first buffers 13 can be arranged on different sides of the plug-in body 12. The number of the second buffers 14 is four, and each second buffer 14 is arranged at a corner position of the base 11, and each second buffer 14 is connected to the plug-in body 12. The four corner positions of the base 11 are connected to the vehicle body through fasteners such as bolts.

[0048] The battery pack 20 of the embodiments of the present application is described below.

[0049] In an embodiment, the battery pack 20 has a first direction Z and a second direction X intersecting each other. The first direction Z and the second direction X can be approximately perpendicular, for example, the included angle between the first direction Z and the second direction X can be 80° to 90°. Preferably, the first direction Z and the second direction X are perpendicular to each other.

[0050] For example, please refer to Figure 6 , the interface assembly 21 of the battery pack 20 includes at least two groups of interface modules 22 adjacent to each other, and each interface module 22 is configured to be plugged with the plug-in assembly 10 alternatively. In the at least two groups of interface modules 22, at least one group of interface modules 22 is configured to be plugged with the plug-in assembly 10 along the first direction Z, and at least one group of interface modules 22 is configured to be plugged with the plug-in assembly 10 along the second direction X.

[0051] By the above manner, compared with the case that the interface assembly 21 of the battery pack 20 only supports plugging with the plug-in assembly 10 on the vehicle body in one direction, the interface assembly 21 of the battery pack 20 in the embodiment is provided with at least two groups of interface modules 22, and the plug-in assembly 10 can be plugged with the corresponding interface module 22 from different directions, which can be compatible with the battery pack 20 replacement scheme of different models of vehicles.

[0052] It should be noted that, based on the example that the plug-in assembly 10 is provided with the first buffer 13 and the second buffer 14 as described above, when the plug-in assembly 10 is plugged with the corresponding interface module 22 along the first direction Z, the plug-in direction P of the plug-in assembly 10 is parallel to the first direction Z, the first buffer 13 can buffer the plug-in body 12 along the first direction Z, and the second buffer 14 can buffer the plug-in body 12 along the second direction X; as shown in Figure 1 When the plug-in assembly 10 is plugged with the corresponding interface module 22 along the second direction X, the plug-in direction P of the plug-in assembly 10 is parallel to the second direction X, the first buffer 13 can buffer the plug-in body 12 along the second direction X, and the second buffer 14 can buffer the plug-in body 12 along the first direction Z. Figure 7

[0053] In an embodiment, the battery pack 20 is provided with a first platform 231 and a second platform 232. The first platform 231 and the second platform 232 are arranged adjacent to each other. The first platform 231 is arranged towards the first direction Z, and the second platform 232 is arranged towards the second direction X. At least one group of interface modules 22 is arranged on the first platform 231, and the interface modules 22 on the first platform 231 are arranged towards the first direction Z, so that the interface modules 22 on the first platform 231 are plugged with the plug-in assembly 10 along the first direction Z. At least one group of interface modules 22 is arranged on the second platform 232, and the interface modules 22 on the second platform 232 are arranged towards the second direction X, so that the interface modules 22 on the second platform 232 are plugged with the plug-in assembly 10 along the second direction X.

[0054] ​In an embodiment, the interface module 22 comprises a first interface 221, a second interface 222 and a third interface 223, which are respectively plugged with the corresponding plug-in components in the plug-in assembly 10. The voltage level of the first interface 221 is greater than that of the second interface 222, that is, the first interface 221 is a high-voltage interface, and the second interface 222 is a low-voltage interface. The first interface 221 is connected to the monomer battery through the corresponding wire harness to provide a high-voltage power source for the whole vehicle. The second interface 222 is used to connect the BMS (Battery Management System) and other low-voltage electronic components. The battery pack 20 is internally provided with a heating element (not shown in the figure), and the third interface 223 is electrically connected with the heating element, and the third interface 223 is configured to control the heating element to heat the monomer battery.

[0055] In other words, the interface module 22 of the embodiment integrates the first interface 221, the second interface 222 and the third interface 223 in one, which can improve the degree of integration, improve the utilization rate of the layout space of the battery pack 20 of the whole vehicle, and can simplify the plugging process of the battery pack 20 and the plug-in assembly 10, and the assembly is convenient and fast, so as to save the time-consuming of battery replacement. The interface module 22 can also be provided with a guide structure for guiding the plugging of the plug-in assembly 10 and the interface module 22.

[0056] In summary, the application provides a plug-in assembly and a vehicle. The first buffer and the second buffer are arranged between the base of the plug-in assembly and the plug-in component body. The first buffer is configured to buffer the plug-in component body along the plugging direction, and the second buffer is configured to buffer the plug-in component body along the direction intersecting the plugging direction. In other words, the first buffer and the second buffer of the application buffer the plug-in component body from different directions, which can reduce the risk of damage to the plug-in assembly. In particular, it is possible to avoid damage to the plug-in assembly caused by the relative position deviation of the plug-in assembly and the external impact force during the battery replacement process, and it is possible to avoid damage to the plug-in assembly caused by the impact force generated by the road bumps during the driving process.
