Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 6 As shown, a power battery aluminum tray comprises a tray 1 and a battery slot 2 arranged inside the tray 1 and extending to the top of the tray 1; a protective mechanism is arranged at the bottom of the tray 1, and a connecting mechanism connected to the protective mechanism is arranged inside and at the bottom of the tray 1, the protective mechanism comprises a metal pad 9 arranged at the bottom of the tray 1, a first buffer pad 3 is fixedly connected to the bottom of the metal pad 9 by gluing, a second buffer pad 4 is fixedly connected to the bottom of the first buffer pad 3 by gluing, the first buffer pad 3 is arranged to be made of copper foil rubber material, and the second buffer pad 4 is arranged to be made of thermal conductive silicone material;

[0026] During operation, after the first buffer pad 3 is bonded to the bottom of the metal pad 9 and the second buffer pad 4 is bonded to the bottom of the first buffer pad 3, the setting of the first buffer pad 3 can be thermally conductive through the metal pad 9, and the excellent electromagnetic shielding performance of the first buffer pad 3 itself can effectively prevent the interference of electromagnetic waves and improve the stability of the entire power battery system. The energy absorption capacity of the metal pad 9 itself can effectively alleviate the impact of gravel when the vehicle is driving. With the setting of the second buffer pad 4, a good buffer and fixing layer is formed at the bottom of the first buffer pad 3 to further improve the protection of the bottom of the tray 1, so as to avoid the chassis of the new energy vehicle frequently colliding with hard objects such as gravel on the road during long-term driving. The gravel directly contacts the tray 1 and is deformed or damaged, thereby reducing the protection performance of the power battery. In addition, copper foil rubber and thermal conductive silicone both have good thermal conductivity, which can further dissipate the heat of the battery in the working state to extend the service life of the battery.

[0027] Furthermore, the connecting mechanism includes a plug-in slot 14 opened inside the tray 1 and extending to the bottom of the tray 1, a connecting slot 17 is provided on one side of the plug-in slot 14, a mounting hole 13 is provided on the top of the connecting slot 17, a limiting slot 11 which is mutually interpenetrating with the connecting slot 17 is provided at one end of the connecting slot 17, a connecting rod 18 is provided inside the limiting slot 11, a connecting column 15 which is fixedly connected to the connecting rod 18 is provided inside the connecting slot 17, a spring 10 which extends to the inside of the connecting slot 17 is fixedly connected inside the mounting hole 13, and the limiting slot 11 and the plug-in slot 14 are connected to each other. A stopper 12 fixedly connected to the inside of the tray 1 is provided at the angle of the groove 14, a connecting block 5 is fixedly connected to the bottom of the connecting column 15, the connecting mechanism also includes a third docking interface 16 provided inside the metal pad 9, a first docking interface 6 is provided inside the first buffer pad 3, an arc groove 7 is provided inside the second buffer pad 4, a second docking interface 8 connected to the arc groove 7 is provided on one side of the arc groove 7, the connecting block 5 is located below the arc groove 7, and the connecting mechanism is provided with multiple groups, and the multiple groups of connecting mechanisms are rectangular as a whole and are respectively located at the four corners of the rectangle;

[0028] During operation, during regular inspection and maintenance of the vehicle, the connecting block 5 is pressed to drive the connecting column 15 to move upward, and the movement of the connecting column 15 drives the connecting rod 18 to move upward to squeeze the spring 10. After the top of the connecting rod 18 fits with the inner top of the limiting groove 11, the connecting block 5 is rotated to drive the connecting rod 18 to rotate with the connecting column 15 as the center, so as to align with the plug-in groove 14 through the top of the stopper 12, and then the connecting block 5 is moved downward to drive the connecting rod 18 to pass through the plug-in groove 14 and separate from the tray 1. Repeating the above operation can release the connection state between the metal pad 9 and the tray 1, so that the staff can inspect or replace the protective mechanism. After completing the inspection operation, the above steps are reversed to make the connecting rod 18 re-engaged in the inner bottom end of the limiting groove 11 under the resetting action of the mounting hole 13, so as to complete the connection operation between the metal pad 9 and the tray 1, and align the third pair of interfaces 16, the second pair of interfaces 8, and the first pair of interfaces 6 with each other, which can facilitate the installation operation.

[0029] Working principle: By setting up a protective structure, by bonding the first buffer pad 3 to the bottom of the metal pad 9, and bonding the second buffer pad 4 to the bottom of the first buffer pad 3, the setting of the first buffer pad 3 can be thermally conductive through the metal pad 9, and through the excellent electromagnetic shielding performance of the first buffer pad 3 itself, it can effectively prevent the interference of electromagnetic waves and improve the stability of the entire power battery system. Through the energy absorption capacity of the metal pad 9 itself, the impact of gravel can be effectively alleviated when the vehicle is driving. With the setting of the second buffer pad 4, a good buffer and fixing layer is formed at the bottom of the first buffer pad 3 to further improve the protection of the bottom of the tray 1, so as to avoid the chassis of the new energy vehicle often colliding with hard objects such as gravel on the road during long-term driving. The gravel directly contacts the tray 1 and is deformed or damaged, thereby reducing the protection performance of the power battery. In addition, copper foil rubber and thermal conductive silicone have good thermal conductivity, which can further dissipate the heat of the battery in the working state to extend the service life of the battery.

[0030] By setting up the protective structure, during the regular inspection and maintenance of the vehicle, the connecting block 5 is pressed to drive the connecting column 15 to move upward, and the movement of the connecting column 15 drives the connecting rod 18 to move upward to squeeze the spring 10. After the top of the connecting rod 18 fits with the inner top of the limiting groove 11, the connecting block 5 is rotated to drive the connecting rod 18 to rotate with the connecting column 15 as the center, so as to align with the plug-in groove 14 through the top of the stopper 12, and then the connecting block 5 is moved downward to drive the connecting rod 18 to pass through the plug-in groove 14 and separate from the tray 1. Repeating the above operation can release the connection state between the metal pad 9 and the tray 1, so that the staff can inspect or replace the protective mechanism. After completing the inspection operation, the above steps are reversed to make the connecting rod 18 re-clamped to the inner bottom end of the limiting groove 11 under the resetting action of the mounting hole 13, so as to complete the connection operation between the metal pad 9 and the tray 1, and align the third pair of interfaces 16, the second pair of interfaces 8, and the first pair of interfaces 6 with each other, which can facilitate the installation operation.
