[0087] In this embodiment, the electric vehicle includes two beams 300 arranged side by side and extending along the length direction of the vehicle, and the body bracket is connected to the beam 300, which is used for detachably installing a quick-change battery pack, including two quick-change battery packs, which are independently installed on both sides of the beam 300, and the connector frame 2 is arranged in the middle of the width direction W of the electric vehicle, and the two quick-change battery packs 200 are respectively arranged on both sides of the connector frame 2 in the width direction W of the electric vehicle. A battery-end connector is provided on the quick-change battery pack, and the vehicle-end connector and the battery-end connector are arranged oppositely. When the quick-change battery pack is installed on the body bracket, the vehicle-end connector and the battery-end connector are connected. In other alternative embodiments, according to the setting position of the quick-change battery pack 200 and the battery replacement method, the connector frame 2 can be correspondingly arranged, for example, in the middle of the length direction L of the electric vehicle, or at the end of the length direction L of the electric vehicle, etc.

[0088] The connector frame 2 is connected to the bracket body 1, avoiding the need to set up another connection structure with the connector frame 2 or the vehicle-end connector 3 on the beam 300 of the vehicle body, reducing the direct connection structure between the connector frame 2 or the vehicle-end connector 3 and the beam 300, reducing the connection accuracy requirements, and eliminating the need to make structural changes to the beam 300 to install the connector frame 2. When the vehicle-end connector 3 needs to be repaired, the connector frame 2 can be removed relative to the vehicle body bracket 100, so that the connector frame 2 and the vehicle-end connector 3 can be taken out as a whole, which facilitates the maintenance of the vehicle-end connector 3 and the vehicle body bracket 100.

[0089] As a preferred implementation, Figure 2 , Figure 3 and Figure 4 As shown, the bracket body 1 includes a connecting plate 4 , the connecting plate 4 is located above the beam 300 , and the connector frame 2 is located below the connecting plate 4 .

[0090] By setting the connecting plate 4, the connector frame 2 can be accurately installed through the flatness of the connecting plate 4, thereby reducing the parallelism and accuracy requirements of the bracket body 1 of the vehicle body bracket 100. The beam 300 and the electrical connector frame 2 are simultaneously connected through the connecting plate 4, simplifying the connection structure of different components and the beam 300, reducing the manufacturing cost of the vehicle body bracket 100, and facilitating the structural setting of the vehicle body bracket 100.

[0091] As a preferred implementation, Figure 5 As shown, the connector frame 2 includes two relatively arranged mounting plates 21, and the vehicle-end connector 3 includes an electrical connector. The mounting plates 21 are each provided with an electrical connector. The top of the mounting plate 21 is provided with a first flange 211 bent in a horizontal direction, and the first flange 211 is provided with a mounting hole, which is used for connecting and installing with the connecting plate 4.

[0092] In other alternative embodiments, two relatively arranged mounting plates can be used to simultaneously dock with the quick-change battery packs on both sides, thereby facilitating the installation of the vehicle-end connector and the integration of the two vehicle-end connectors.

[0093] The two quick-change battery packs 200 are connected to the electrical connectors from both sides of the connector frame 2. By setting the electrical connectors on the mounting plate 21, when the electrical connectors need to be repaired, the connector frame 2 can be removed relative to the vehicle body bracket 100, and the connector frame 2 and the electrical connectors can be taken out as a whole, which is convenient for the maintenance of the electrical connectors and the vehicle body bracket 100, avoids the connection between the electrical connectors and the vehicle body beam 300, and simplifies the structural setting of the vehicle body beam 300. The first flange 211 increases the connection area between the connector frame 2 and the connecting plate 4, which is beneficial to the connection reliability between the connector frame 2 and the connecting plate 4.

[0094] As a preferred implementation, Figure 4 , Figure 5 and Figure 6 As shown, a first connecting member 5 is provided on one side of the mounting plate 21 facing the battery pack 200. The first connecting member 5 includes a vertical mounting portion 51 and a horizontal mounting portion 52, which are respectively used to connect to the mounting plate 21 and the connecting plate 4. The vertical mounting portion 51 and the horizontal mounting portion 52 are vertically arranged.

[0095] The provision of the first connecting member 5 is beneficial to the connection reliability between the connector frame 2 and the connecting plate 4, is beneficial to reducing the swing amplitude of the connector frame 2 caused by impact in a direction perpendicular to the mounting plate 21, and is beneficial to the connection between the battery pack 200 and the vehicle-end connector 3.

[0096] As a preferred implementation, Figure 5 As shown, the horizontal mounting portion 52 and the first flange 211 are respectively located on both sides of the mounting plate 21. When the connector frame 2 is swung or deformed by an impact in a direction perpendicular to the mounting plate 21, the interaction between the horizontal mounting portion 52 of the first connector 5 and the first flange 211 is beneficial to the resetting of the mounting plate 21 of the connector frame 2, thereby facilitating the reliability of the vehicle body bracket 100 and the success rate of battery replacement.

[0097] As a preferred implementation, Figure 5 and Figure 6As shown, second flanges 53 are provided on both sides of the vertical mounting portion 51 .

[0098] The second flange 53 is provided to improve the overall strength of the first connecting member 5, reduce the risk of deformation of the first connecting member 5, and facilitate the connection between the first connecting member 5 and the connecting plate 4 and the connector frame 2, thereby improving the connection reliability between the connecting plate 4 and the connector frame 2.

[0099] As a preferred implementation, Figure 3 , Figure 4 and Figure 7 As shown, the vehicle body bracket 100 further includes a second connector, and third flanges 212 are provided on both sides of the mounting plate 21, and the two ends of the second connector 6 are respectively connected to the third flanges 212 and the edge of the connecting plate 4. Specifically, in this embodiment, in the width direction W of the electric vehicle, one end of the second connector 6 is connected to the middle of the edge of the connecting plate 4, and the other end is connected to the third flange 212, and the second connector, the connecting plate 4 and the third flange 212 form a triangular structure.

[0100] The third flange 212 improves the overall strength of the mounting plate 21 and reduces the risk of deformation of the mounting plate 21, which is beneficial to the connection reliability between the second connector 6 and the mounting plate 21. The second connector 6 is provided to reduce the swing amplitude of the connector frame 2 in the direction perpendicular to the mounting plate 21, which is beneficial to the connection between the battery pack 200 and the vehicle-end connector 3.

[0101] The top, side and connecting plate 4 of the connector frame 2 are connected to each other through the first flange 211 , the first connecting member 5 and the third flange 212 , thereby improving the connection strength between the connector frame 2 and the connecting plate 4 from multiple directions.

[0102] As a preferred implementation, Figure 7 As shown, the second connecting member 6 is bent into shape, and the second connecting member has a first bending surface 61 and a second bending surface 62. The first bending surface 61 is attached to the edge of the third flange 212 and the connecting plate 4, and is connected to the third flange and the connecting plate. The first bending surface 61 is perpendicular to the second bending surface 62.

[0103] The above arrangement is beneficial to the overall strength of the second connecting member, reduces the risk of deformation of the second connecting member, and is beneficial to the connection between the second connecting member 6 and the connecting plate 4 and the mounting plate 21, thereby improving the connection reliability between the connecting plate 4 and the mounting plate 21.

[0104] As a preferred implementation, Figure 3 and Figure 4As shown, a third connecting member 7 is provided at the bottom of the connecting plate 4 , and the third connecting member 7 is used to be connected to the beam 300 . The third connecting member 7 and the first connecting member 5 are respectively located on both sides of the beam 300 .

[0105] Through the above arrangement, there is a gap between the first connecting member 5 and the third connecting member 7, and the beam 300 passes through the gap. When the body bracket 100 and the beam 300 are connected, it does not interfere with other structures on the beam 300. The third connecting member 7 is arranged at the bottom of the connecting plate 4 to facilitate the connection between the connecting plate 4 and the beam 300; the connecting plate 4 is erected above the beam 300, and the beam 300 is conducive to the beam 300 carrying the body bracket 100 and the battery pack 200 connected to the body bracket 100, reducing the risk of bending of the beam 300, simplifying the connection between the body bracket 100 and the electric vehicle, and facilitating the connection reliability between the body bracket 100 and the vehicle and the battery pack 200.

[0106] As a preferred implementation, Fig. 9 As shown, the third connecting member 7 is bent and formed, and has a first connecting surface 71 and a second connecting surface 72 . The first connecting surface 71 is connected to the bottom of the connecting plate 4 , and the second connecting surface 72 is perpendicular to the first connecting surface 71 and is used to connect to the beam 300 .

[0107] The connection areas between the third connecting member 7 and the beam 300 and the connecting plate 4 are increased by the first connecting surface 71 and the second connecting surface 72 which are perpendicular to each other, which is beneficial to the connection reliability between the beam 300 and the vehicle body bracket 100 .

[0108] As a preferred implementation, Fig. 9 As shown, the third connecting member 7 includes a reinforcing rib 73 , which is perpendicular to the first connecting surface 71 and the second connecting surface 72 , and is connected to the first connecting surface 71 and the second connecting surface 72 .

[0109] By providing the reinforcing rib 73 , the overall strength of the third connecting member 7 is increased and the risk of deformation of the third connecting member 7 due to stress is reduced, which is beneficial to the connection reliability between the beam 300 and the body bracket 100 and the accurate installation of the body bracket 100 relative to the beam 300 .

[0110] As a preferred implementation, Figure 3 and Figure 4 As shown, the bottoms of the two mounting plates 21 are connected via a fourth connecting member 22 .

[0111] The fourth connecting member 22 supports the relative position of the two mounting plates 21, thereby improving the integrity of the connector frame 2 and the stability of the relative position of the two mounting plates 21, which is beneficial to reducing the swing amplitude of the connector frame 2 caused by impact in the direction perpendicular to the mounting plates 21, and is beneficial to the connection between the battery pack 200 and the vehicle-end connector 3.

[0112] In other alternative embodiments, a plurality of fourth connecting members 22 may be arranged at intervals in the height direction to reduce the risk of deformation of the mounting plate 21 of the connector frame 2 .

[0113] As a preferred embodiment, the fourth connecting member 22 extends from the bottom of the mounting plate 21 to the mounting plates 21 on both sides, which can reduce the risk of failure of the battery pack 200 or the vehicle-end connector 3 at the connection position due to splashing of mud and water.

[0114] As a preferred implementation, Figure 3 , Figure 4 and Figure 5 As shown, the mounting plate 21 is also provided with a heat dissipation port 23, and the heat dissipation port 23 is provided at the bottom of the connector frame 2. Specifically, the heat dissipation port 23 is provided as a honeycomb structure composed of a plurality of hexagons. In other alternative embodiments, the heat dissipation port 23 can also be provided in the shape of a long strip, a round hole, a triangular hole or a square hole.

[0115] The above arrangement prevents the beam 300 from interfering with the heat dissipation of the electrical connection components of the electric vehicle. Under the premise that the connector frame 2 is connected with the connecting plate 4, the length of the mounting plate 21 of the connector frame 2 may exceed the necessary installation length required for setting the vehicle-end connector 3, resulting in the connector frame 2 being too long and having useless space. By setting the heat dissipation port 23, the weight of the connector frame 2 can be reduced without affecting the setting of the connector frame 2 and the connecting plate 4.

[0116] As a preferred implementation, Figure 3 , Figure 4 and Figure 5 As shown, the vehicle-end connector 3 has an extension portion 31 extending outward from the mounting plate 21; the mounting plate 21 is also provided with a protective plate 24, the protective plate 24 and the extension portion 31 are located on the same side of the mounting plate 21, and the length of the protective plate 24 extending outward from the mounting plate 21 matches the length of the extension portion 31.

[0117] By providing a protection plate 24, the connection mechanism between the battery pack 200 and the vehicle-end connector 3 is protected, and the risk of failure of the battery pack 200 or the vehicle-end connector 3 at the connection position due to splashing of mud and water is reduced, which is beneficial to the safe use of the vehicle body bracket 100 and the battery pack 200.

[0118] Specifically, in this embodiment, two quick-change battery packs 200 are respectively arranged on both sides of the connector frame 2 in the width direction W of the electric vehicle; accordingly, the protective plate 24 is arranged on both sides of the mounting plate 21 in the length direction L of the electric vehicle, and the upper and lower ends of the protective plate 24 are bent in the direction close to the extension portion 31.

[0119] As a preferred implementation, Figure 2 and Figure 4 As shown, the vehicle body support 100 further includes a reinforcing beam 8 , which is arranged across the main beam 300 and connected to the connecting plate 4 .

[0120] Battery pack mounting assemblies are respectively provided on both sides of the beam 300, and the battery pack mounting assemblies include locking mechanisms for locking the battery packs on both sides. By arranging a reinforcing beam 8 above the beam 300, it is convenient to connect the battery pack mounting assemblies on both sides of the beam 300, so that the battery pack mounting assemblies on both sides form a whole, which is beneficial to the connection reliability between the connecting plate 4 and the battery pack 200 mounting assembly, and is beneficial to the overall strength of the vehicle body bracket 100.
