[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] Embodiment 1, as Figure 1-Figure 4 As shown, a new energy vehicle power battery tray based on aluminum alloy can clamp the power line through the clamping assembly 11 on the partition 10 when the power battery tray body 1 is pre-assembled with batteries. The power line distribution is planned by clamping the clamping assembly 11. At the same time, a mounting frame 3 is installed at the bottom of the power battery tray body 1. The mounting frame 3 drives the protective net 4 to be installed to the bottom of the power battery tray body 1. The protective net 4 drives the connecting plate 5 to drive the blocking rod 6 and the limiting frame 7. The metal mounting sheet 8 passes through the limiting frame 7 and is limited by the limiting frame 7. After entering the limit frame 7, the notch of the metal mounting piece 8 passes through the baffle rod 6, and the metal mounting piece 8 drives the protective plate 9 to be tightly attached to the bottom of the connecting plate 5. The slide groove opened on the protective plate 9 is received in the limit frame 7 extending from the bottom of the connecting plate 5. Under the push of the protective plate 9, the notch of the metal mounting piece 8 is tightly attached to the bottom of the baffle rod 6, and one side of the baffle rod 6 is limited to one side of the notch opened by the metal mounting piece 8 to prevent the metal mounting piece 8 from sliding out of the limit frame 7, so that the metal mounting piece 8 tightens the protective plate 9 and fixes it to the bottom of the connecting plate 5, thereby completing the protection of the bottom of the protective net 4.

[0029] Embodiment 2, as Figure 2-Figure 4As shown, a new energy vehicle power battery tray based on aluminum alloy is used. At the bottom of the protective net 4, each connecting plate 5 is used in conjunction with the corresponding protective plate 9 as protection and integrated at the bottom of the protective net 4. A single connecting plate 5 and a protective plate 9 form a protection module, and a plurality of protection modules are combined as the bottom protection of the protective net 4. When a single protective plate 9 at the bottom of the protective net 4 is slightly scratched, the protective plate 9 transmits the force to the connecting plate 5 and then disperses it to the protective net 4 as a whole to reduce the scratch force on the single protective plate 9. When a single protective plate 9 at the bottom of the protective net 4 is seriously damaged, the metal mounting plate 8 is driven by pulling the damaged protective plate 9 to cut and separate the metal mounting plate 8 from the protective plate 9. After the metal mounting plate 8 is no longer limited by the protective plate 9, the old metal mounting plate 8 is removed, and a new protective plate 9 and a metal mounting plate 8 are replaced and installed at the bottom of the connecting plate 5, thereby completing the replacement of the seriously damaged protective plate 9.

[0030] Embodiment three, as Figure 5 and Figure 6 As shown, a new energy vehicle power battery tray based on aluminum alloy, when the power battery power line is clamped by the clamping assembly 11, the staff pulls the power line and places it on the second arc plate 16 in the arc block 12, and uses the power line to press on the second arc plate 16, pushes the movable plate 13 to drive the extension block 18 to stretch the elastic rubber column 19 in the groove opened in the arc block 12, and the movable plate 13 is rotated and pressed down in the groove opened in the arc block 12, and the power line is bound and stored in the second arc plate 16 on the inner side of the arc block 12 by the movable plate 13, and one end of the movable plate 13 is pressed on the stopper 21, and the movable plate 13 presses down the stopper 21 to compress the rubber block 20, and the stopper 21 squeezes the rubber block 20 and retreats into the storage groove opened in the arc block 12 The stopper 21 is moved back to its original position under the elastic force of the rubber block 20, and the bottom of the stopper 21 enters the limiting groove opened by the movable plate 13, and the upper part of the stopper 21 is limited by the top of the inner wall of the storage groove opened by the arc block 12, so that the stopper 21 cannot be folded upward, and the stopper 21 limits the movable plate 13 in the arc block 12, thereby limiting and restraining the power cord on the second arc plate 16 on the inner side of the arc block 12, and limiting and restraining the power cord through the clamping assembly 11 on the partition 10, so as to facilitate the staff to install the power cord in the power battery tray body 1.

[0031] When the movable panel 13 needs to be opened, the rubber block 20 is compressed by pushing the stopper 21, and the stopper 21 goes deep into the storage groove opened by the arc block 12. The stopper 21 no longer limits the movable panel 13, and the movable panel 13 rotates back to its original position in the groove opened by the arc block 12 driven by the elastic force of the elastic rubber column 19 itself, so that the movable panel 13 is opened, making it convenient for the staff to take out the power cord originally pressed under the movable panel 13 for adjustment.

[0032] It should be noted that the present invention is a new energy vehicle power battery tray based on aluminum alloy. When in use, the protective component 2 is used as additional protection for the bottom of the power battery tray main body 1. When a slight scratch occurs on the bottom of the car, the protective component 2 replaces the power battery tray main body 1, and the bottom of the power battery tray main body 1 will not be damaged by the slight scratch, thereby extending the service life of the power battery tray main body 1 and more effectively protecting the power battery inside the power battery tray main body 1. When the protective component 2 replaces the power battery tray main body 1 to be scratched, the protective net 4 installed in the mounting frame 3 included in the protective component 2 serves as an integrated net, and the bottom connecting plate 5 of the protective net 4 cooperates with the corresponding protective plate 9 modular combination. If a single protective plate 9 is damaged, the corresponding protective plate 9 is replaced, and the entire protective component 2 does not need to be replaced due to damage to the protective plate 9, thereby extending the overall service life of the protective component 2 and saving maintenance costs. The protective plate 9 is installed in the bottom limit frame 7 of the connecting plate 5 through the metal mounting plate 8. The installation is simple, which is convenient for staff to disassemble and replace, saving maintenance time.

[0033] When the second arc plate 16 in the arc block 12 cooperates with the movable plate 13 to limit and clamp the power line, the adjusting screw rod 17 can be raised and lowered on the arc block 12 through the thread by twisting the adjusting screw rod 17, and the adjusting screw rod 17 drives the first arc plate 14 to rise and fall in the arc block 12, and the first arc plate 14 drives the elastic rubber pad 15 to drive the second arc plate 16 to rise and fall in the arc block 12, thereby adjusting the clamping range between the second arc plate 16 and the movable plate 13, which is convenient for the staff to adjust the clamping range according to the specific number of power lines to be clamped. The size can be adjusted, the application scope is wider, and the practicality is stronger. After the height of the second arc plate 16 in the arc block 12 is adjusted by adjusting the screw rod 17 to rise and fall in the arc block 12, the power cord is pressed on the second arc plate 16, and the second arc plate 16 compresses the elastic rubber pad 15 on the first arc plate 14. Under the action of its own elastic force, the elastic rubber pad 15 pushes the second arc plate 16 based on the first arc plate 14 to clamp the power cord under the movable plate 13. The adjustment structure is simple and convenient for staff to operate.

[0034] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
