Description

Technical Field

[0001] This invention relates to the field of power battery tray technology, and in particular to a new energy vehicle power battery tray based on aluminum alloy. Background Technology

[0002] Based on their scope, new energy vehicles can be divided into broad and narrow definitions. Broadly defined, new energy vehicles, also known as alternative fuel vehicles, include pure electric vehicles and fuel cell electric vehicles that use all non-petroleum fuels, as well as hybrid electric vehicles and ethanol gasoline vehicles that partially use non-petroleum fuels. All existing new energy vehicles are included in this concept. Narrowly defined, new energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technologies, structures, and principles. Existing new energy vehicles use power batteries as their power source. The power batteries of new energy vehicles are usually installed at the bottom of the vehicle through a power battery tray. Currently, to balance lightweighting and sturdiness, the power battery trays of new energy vehicles are mostly made of aluminum alloy in one piece.

[0003] Existing aluminum alloy-based battery trays for new energy vehicles offer insufficient protection after installation on the bottom of the vehicle. Damage to the bottom of the battery tray reduces its protective capability for the internal battery, creating safety hazards. Furthermore, since these battery trays are typically manufactured as a single piece of aluminum alloy, repairs require a complete overhaul, resulting in a cumbersome and costly process. The internal structure of the battery tray also makes it difficult to secure power cables, negatively impacting user experience. To address these shortcomings, we propose an aluminum alloy-based battery tray for new energy vehicles. Summary of the Invention

[0004] The main objective of this invention is to provide a new energy vehicle power battery tray based on aluminum alloy, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A new energy vehicle power battery tray based on aluminum alloy includes a power battery tray body. A protective component is provided at the bottom of the power battery tray body. The protective component includes a mounting frame, the top of which is detachably mounted to the bottom of the power battery tray body. A protective net is detachably mounted inside the mounting frame. Multiple sets of connecting plates are evenly and detachably mounted at the bottom of the protective net. A square hole is opened at the top of each connecting plate, and a stop bar is symmetrically and detachably mounted inside the square hole. A limit frame is symmetrically and detachably mounted at the bottom of each connecting plate, and a metal safety device is slidably connected inside the limit frame. The mounting plate has a protective plate detachably mounted on one end. Multiple sets of partitions are detachably and evenly mounted inside the main body of the power battery tray. Two clamping assemblies are symmetrically arranged on the top of each partition. Each clamping assembly includes an arc-shaped block with a groove on one side of its top. A movable plate is rotatably connected inside the groove of the arc-shaped block. A first arc-shaped plate symmetrically abuts against the bottom inner side of the arc-shaped block. An elastic rubber pad is detachably mounted on the top of the first arc-shaped plate, and a second arc-shaped plate is detachably mounted on the top of the elastic rubber pad. Two adjusting screws symmetrically and movably pass through the top of the second arc-shaped plate.

[0007] Preferably, the bottom of the power battery tray body abuts against the top of the protective net, and one side of the bottom of the protective net abuts against the top of the baffle.

[0008] Preferably, the top of the protective plate is provided with a sliding groove, and the outer side of the limiting frame is slidably connected to the inside of the sliding groove of the protective plate.

[0009] Preferably, a notch is provided on one side of the metal mounting plate, and the inside of the notch abuts against the outside of the stop bar.

[0010] Preferably, the top side of the metal mounting plate abuts against the bottom side of the connecting plate, and the top side of the metal mounting plate abuts against the bottom of the protective net.

[0011] Preferably, the width of the partition is the same as the width of the arc-shaped block, and the top of the arc-shaped block is flush with the top of the partition.

[0012] Preferably, one end of the adjusting screw is threaded to the bottom inner side of the arc-shaped block, and the other end of the adjusting screw is rotatably connected to the bottom of the first arc-shaped plate.

[0013] Preferably, the adjusting screw passes through one end of the second arc-shaped plate and movably passes through the top of the elastic rubber pad. The width of the elastic rubber pad is the same as the width of the first arc-shaped plate, and the width of the elastic rubber pad is one-quarter of the width of the second arc-shaped plate.

[0014] Preferably, an extension block is detachably installed on one side of the movable plate, and an elastic rubber column is detachably installed at the bottom of the extension block. The bottom of the elastic rubber column is detachably installed to the bottom of the inner wall of the groove opened in the arc-shaped block.

[0015] Preferably, a storage groove is provided on one side of the inner wall of the arc-shaped block, and a rubber block is detachably installed inside the storage groove of the arc-shaped block. A stop block is detachably installed on one side of the top of the rubber block, and a limiting groove is provided at one end of the movable plate. The width of the stop block is the same as the width of the limiting groove of the movable plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, by setting up a protective component as additional protection for the bottom of the power battery tray body, when the bottom of the car is slightly scratched, the protective component acts as a substitute for the power battery tray body, and the bottom of the power battery tray body will not be damaged by the slight scratch, thus extending the service life of the power battery tray body and more effectively protecting the power battery inside the power battery tray body.

[0018] 2. In this invention, the connecting plate and the corresponding protective plate are modularly combined at the bottom of the protective net. If a single protective plate is damaged, the corresponding protective plate is replaced. The entire protective component will not be replaced due to the damage of a protective plate, thus extending the overall service life of the protective component and saving maintenance costs. The protective plate is installed in the bottom limiting frame of the connecting plate by a metal mounting plate. The installation is simple and convenient for workers to disassemble and replace, saving maintenance time.

[0019] 3. In this invention, the movable plate rotates and presses down within the groove of the arc-shaped block to bind and store the power cord inside the second arc-shaped plate on the inner side of the arc-shaped block. This makes it convenient for workers to install the power cord inside the power battery tray body. By turning the adjusting screw, the height of the second arc-shaped plate within the arc-shaped block can be adjusted, thereby adjusting the clamping range between the second arc-shaped plate and the movable plate. This allows workers to adjust the size according to the specific number of power cords to be clamped, making it more widely applicable and more practical. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1, as Figures 1-4 As shown, a new energy vehicle power battery tray based on aluminum alloy allows power cables to be clamped by clamping components 11 on the partition 10 during battery pre-assembly of the power battery tray body 1. The clamping components 11 are used to plan the distribution of the power cables. Simultaneously, an mounting frame 3 is installed at the bottom of the power battery tray body 1. The mounting frame 3 drives a protective net 4 to be installed at the bottom of the power battery tray body 1. The protective net 4 drives a connecting plate 5, a stop bar 6, and a limiting frame 7. The metal mounting piece 8, passing through the limiting frame 7, is constrained by the limiting frame 7. After entering the limiting frame 7, the notch of the metal mounting piece 8 passes through the stop bar 6, and the metal mounting piece 8 drives the protective plate 9 to stick tightly to the bottom of the connecting plate 5. The sliding groove opened in the protective plate 9 is housed in the limiting 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 sticks tightly to the bottom of the stop bar 6. One side of the stop bar 6 limits the notch opened in the metal mounting piece 8 to prevent the metal mounting piece 8 from sliding out of the limiting frame 7. Thus, the metal mounting piece 8 pulls the protective plate 9 to the bottom of the connecting plate 5 and completes the protection of the bottom of the protective net 4.

[0029] Example 2, as Figures 2-4As shown, a new energy vehicle power battery tray based on aluminum alloy integrates various connecting plates 5 with corresponding protective plates 9 at the bottom of the protective net 4. Each connecting plate 5 and protective plate 9 forms a protective module, and multiple protective modules are combined to protect the bottom 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 distributes it to the entire protective net 4, reducing the scratching force on the single protective plate 9. When a single protective plate 9 at the bottom of the protective net 4 is severely damaged, the damaged protective plate 9 is pulled to drive the metal mounting piece 8, cutting and separating the metal mounting piece 8 from the protective plate 9. After the metal mounting piece 8 is no longer limited by the protective plate 9, the old metal mounting piece 8 is removed, and a new protective plate 9 and metal mounting piece 8 are installed at the bottom of the connecting plate 5, thereby completing the replacement of the severely damaged protective plate 9.

[0030] Example 3, as Figure 5 and Figure 6 As shown, a new energy vehicle power battery tray based on aluminum alloy, when using the clamping assembly 11 to clamp the power battery power cable, the operator pulls the power cable and places it on the second arc plate 16 inside the arc block 12. The power cable presses against the second arc plate 16, pushing the movable plate 13 to cause the extension block 18 to stretch the elastic rubber column 19 within the groove of the arc block 12. The movable plate 13 rotates and presses down within the groove of the arc block 12, using the movable plate 13 to bind and store the power cable inside the second arc plate 16 on the inner side of the arc block 12. One end of the movable plate 13 presses against the stop block 21, and the movable plate 13 presses down on the stop block 21 to compress the rubber block 20. The stop block 21 squeezes the rubber block 20 back into the storage groove of the arc block 12. The movable plate 13 is fully inserted into the arc-shaped block 12. After the movable plate 13 is fully inserted into the arc-shaped block 12, it passes through the stop block 21. The stop block 21 is no longer subjected to the downward pressure of the movable plate 13. Under the elastic force of the rubber block 20, the stop block 21 returns to its original position. The bottom of the stop block 21 enters the limiting groove opened in the movable plate 13. The top of the stop block 21 is limited by the top of the inner wall of the storage groove opened in the arc-shaped block 12, so the stop block 21 cannot be folded upward. The stop block 21 limits the movable plate 13 within the arc-shaped block 12, thereby limiting and binding the power cord on the second arc-shaped plate 16 inside the arc-shaped block 12. The clamping component 11 on the partition 10 limits and binds the power cord, making it convenient for staff to install the power cord in the power battery tray body 1.

[0031] When it is necessary to open the movable plate 13, by pushing the stop 21 to compress the rubber block 20, the stop 21 goes deep into the storage groove opened in the arc block 12. The stop 21 no longer restricts the movable plate 13. Under the action of the elastic rubber column 19, the movable plate 13 rotates back to its original position in the groove opened in the arc block 12, thereby opening the movable plate 13, making it convenient for staff to take out the power cord that was originally pressed under the movable plate 13 for adjustment.

[0032] It should be noted that this invention is a new energy vehicle power battery tray based on aluminum alloy. In use, the protective component 2 serves as additional protection for the bottom of the power battery tray body 1. When the bottom of the car is slightly scratched, the protective component 2 acts as a replacement for the power battery tray body 1, preventing damage to the bottom of the power battery tray body 1 from minor scratches, thus extending the service life of the power battery tray body 1 and more effectively protecting the power battery inside the power battery tray body 1. While the protective component 2 replaces the power battery tray body 1 in the event of a scratch, the protective net 4 installed in the mounting frame 3 included in the protective component 2 acts as an integrated net. The bottom connecting plate 5 of the protective net 4 is modularly combined with the corresponding protective plate 9. If a single protective plate 9 is damaged, the corresponding protective plate 9 can be replaced, without replacing the entire protective component 2 due to the damage of a protective plate 9, thus extending the overall service life of the protective component 2 and saving maintenance costs. The protective plate 9 is installed in the bottom limiting frame 7 of the connecting plate 5 through a metal mounting piece 8, which is simple to install, convenient for workers to disassemble and replace, and saves maintenance time.

[0033] When using the second arc-shaped plate 16 within the arc-shaped block 12 in conjunction with the movable plate 13 to limit and clamp the power cord, the adjusting screw 17 can be adjusted up and down on the arc-shaped block 12 by turning the adjusting screw 17. The adjusting screw 17 drives the first arc-shaped plate 14 to rise and fall within the arc-shaped block 12, and the first arc-shaped plate 14 drives the elastic rubber pad 15 to rise and fall within the arc-shaped block 12, thereby adjusting the clamping range between the second arc-shaped plate 16 and the movable plate 13, which is convenient for the staff to adjust according to the specific number of power cords to be clamped. The size can be adjusted, making it more widely applicable and more practical. After adjusting the height of the second arc plate 16 within the arc block 12 by adjusting the screw 17, the power cord is pressed on the second arc plate 16. The second arc plate 16 compresses the elastic rubber pad 15 on the first arc plate 14. Under 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 operators.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
