When the battery's own gravity presses against the upper part of the bent part, the battery presses against the bent part to squeeze the spring, the spring contracts, the bent part approaches and fits the battery placement platform, and when the bent part moves downward, it drives the metal curved connecting rod to flip inward relative to the battery placement platform, and the electrode replacement column at the bottom of the power replacement interface pressure plate of the metal curved connecting rod moves downward to fit the corresponding battery charging and discharging electrode. In this way, the arrangement of the battery on the battery placement platform is realized, and the connection between the electrode replacement column and the battery is realized to ensure reliable operation of the battery.

DETAILED DESCRIPTION

[0021] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connection relationships of the components involved, the functions and working principles of the components, etc., by referring to the accompanying drawings:

[0022] As attached Figure 1 , Attachment Figure 2As shown, the utility model is a battery arrangement structure for electric vehicles, a battery placement platform 6 is arranged on the vehicle body 11, a battery arrangement device is arranged on the battery placement platform 6, one side of the battery placement platform 6 is movably connected to the lower part of the metal curved connecting rod 4, a bending part 8 is fixedly arranged at the lower part of the metal curved connecting rod 4, a spring 5 is connected between the bending part 8 and the battery placement platform 6, the upper part of the metal curved connecting rod 4 is connected to the power exchange interface pressure plate 7, and the lower part of the power exchange interface pressure plate 7 is provided with a power exchange electrode column 3. The above structure proposes an improved technical solution to the deficiencies in the prior art. When the structure is set up, a battery placement platform 6 is arranged at a corresponding position set on the vehicle body 11. The size of the battery placement platform 6 is slightly larger than the battery 1 to meet the placement requirements of the battery. One side of the battery placement platform 6 is movably connected to the lower part of the metal curved connecting rod 4. The metal curved connecting rod 4 can be flipped in different directions relative to the battery placement platform 6 (i.e., flipped outward and flipped inward), and a bending portion 8 is fixedly set at the lower part of the metal curved connecting rod 4. A spring 5 is connected between the bending portion 8 and the battery placement platform 6. In this way, under the elastic force of the spring 5, the normal state of the bending portion 8 is to be away from the battery placement platform 6. The upper part of the metal curved connecting rod 4 is connected to the battery replacement interface pressure plate 7, and the lower part of the battery replacement interface pressure plate 7 is provided with a battery replacement electrode column 3. When the battery replacement electrode column 3 is connected to the battery charging and discharging electrodes, the circuit is connected. In this way, when it is necessary to place a new battery 1 on the new energy vehicle 13, the battery 1 is placed on the battery placement platform 6. When the battery 1's own gravity presses against the upper part of the bent portion 8, the battery 1 presses against the bent portion 8 to squeeze the spring 5, the spring 5 contracts, the bent portion 8 approaches and fits the battery placement platform 6, and when the bent portion 8 moves downward, it drives the metal curved connecting rod 4 to flip inward relative to the battery placement platform 1, and the electrode replacement column 3 at the lower part of the power replacement interface pressure plate 7 of the metal curved connecting rod 4 moves downward to fit the corresponding battery charging and discharging electrode. In this way, the arrangement of the battery 1 on the battery placement platform 6 is realized, and the connection between the electrode replacement column 3 and the battery is realized, ensuring that the battery works reliably. When the battery 1 needs to be replaced, when the operator moves the battery 1 away from the battery placement platform 6, the external force applied by the battery disappears, and the spring 5 is reset. The force of the spring can push the bent portion 8 at the bottom of the metal curved connecting rod 4 to move upward, so that the metal curved connecting rod 4 flips outward relative to the battery placement platform 6, and the electrode replacement column 3 at the bottom of the battery replacement interface pressure plate 7 of the metal curved connecting rod 4 leaves the corresponding battery charging and discharging electrode. In this way, not only the electrode replacement column leaves the battery 1, but also the battery replacement interface pressure plate 7 leaves the battery 1, and will not form a constraint on the battery 1 from above, making it easy to move the battery 1. In summary, the electric vehicle battery layout structure described in the utility model has a simple structure. In the battery replacement operation of new energy vehicles, the battery replacement operation is simple, quick and labor-saving, and work efficiency is improved. The reliability of the battery circuit connection after the battery replacement is ensured, and the reliability and use requirements of the battery layout of electric vehicles are met.

[0023] A battery band 12 is provided on the other side of the battery placement platform 6. In this way, when the battery needs to be fixed, one side of the battery is fixed to the battery placement platform 6 by the battery arrangement device, and the battery band 12 on the other side of the battery placement platform 6 fixes the battery 1, so as to achieve reliable positioning of the battery. When the battery is fixed, the battery band is fixed after the battery arrangement device reliably fixes the battery. When taking away the battery, it is necessary to remove the battery band first, and then lift the battery to achieve taking away. When the battery is placed, on the one hand, the positive pole of the battery replacement electrode column 3 of the battery replacement interface pressure plate 7 of the battery arrangement device can be reliably pressed against the charging and discharging positive pole 2 position, and the negative pole of the battery replacement electrode column 3 of the battery replacement interface pressure plate 7 can be reliably pressed against the charging and discharging negative pole 9 position, so as to reliably achieve the connection between the battery and the power cord, and the battery replacement interface pressure plate 7 applies pressure on the battery from above to prevent the battery from moving.

[0024] The lower part of the metal curved connecting rod 4 is movably connected to one side of the battery placement platform 6 through a hinge, and the metal curved connecting rod 4 is set to be a C-shaped structure. With the above structure, the metal curved connecting rod 4 and the battery placement platform 6 can be flipped to meet the needs of putting in or taking out the battery.

[0025] A power line is arranged inside the metal curved connecting rod 4, one end of the power line is connected to the exchange electrode column 3 at the bottom of the exchange interface pressure plate 7, and the other end of the power line is connected to the power supply line. In the above structure, when the exchange electrode column 3 at the bottom of the electric interface pressure plate contacts the corresponding charge and discharge electrode column, the circuit is connected.

[0026] When the battery 1 leaves the battery placement platform 6, the spring 5 is configured to push the bent portion 8 at the bottom of the metal curved connecting rod 4 to move upward, the metal curved connecting rod 4 flips upward, and the exchange electrode column 3 at the bottom of the exchange interface pressure plate 7 of the metal curved connecting rod 4 leaves the corresponding battery charging and discharging electrode structure. The above structure facilitates the removal of the battery from the arrangement position.

[0027] When the battery 1 is placed on the battery placement platform 6 and pressed against the upper part of the bent portion 8, the battery 1 is configured to be able to press against the bent portion 8 to compress the spring 5 to contract. When the battery 1 is pressed against the bent portion 8 to compress the spring 5 to contract, the metal curved connecting rod 4 is configured to be able to flip inward, and the exchange electrode column 3 at the lower part of the exchange interface pressure plate 7 of the metal curved connecting rod 4 fits the structure of the corresponding battery charging and discharging electrode. The above structure facilitates the placement of the battery in the layout position.

[0028] The battery placement platform 6 is provided with a positioning hole 10 on the top and a positioning pin on the bottom of the battery 1. With the above structure, when the battery is placed on the battery placement platform, the positioning pin is inserted into the corresponding positioning hole to achieve horizontal positioning and prevent the battery 1 from moving relative to the battery placement platform 6.

[0029] The electric vehicle battery arrangement structure described in the utility model, when the structure is set, a battery placement platform 6 is arranged at a corresponding position set on the vehicle body 11, the size of the battery placement platform 6 is slightly larger than the battery 1, to meet the placement requirements of the battery, one side of the battery placement platform 6 is movably connected to the lower part of the metal curved connecting rod 4, the metal curved connecting rod 4 can be flipped in different directions relative to the battery placement platform 6 (i.e., flipped outward and flipped inward), and a bending portion 8 is fixedly arranged at the lower part of the metal curved connecting rod 4, a spring 5 is connected between the bending portion 8 and the battery placement platform 6, so that, under the elastic force of the spring 5, the normal state of the bending portion 8 is to be away from the battery placement platform 6, the upper part of the metal curved connecting rod 4 is connected to the battery replacement interface pressure plate 7, the lower part of the battery replacement interface pressure plate 7 is provided with a replacement electrode column 3, and the circuit is connected when the replacement electrode column 3 is connected to the battery charging and discharging electrodes. In this way, when it is necessary to place a new battery 1 on the new energy vehicle 13, the battery 1 is placed on the battery placement platform 6. When the battery 1's own gravity presses against the upper part of the bent portion 8, the battery 1 presses against the bent portion 8 to squeeze the spring 5, the spring 5 contracts, the bent portion 8 approaches and fits the battery placement platform 6, and when the bent portion 8 moves downward, it drives the metal curved connecting rod 4 to flip inward relative to the battery placement platform 1, and the electrode replacement column 3 at the lower part of the power replacement interface pressure plate 7 of the metal curved connecting rod 4 moves downward to fit the corresponding battery charging and discharging electrode. In this way, the arrangement of the battery 1 on the battery placement platform 6 is realized, and the connection between the electrode replacement column 3 and the battery is realized, ensuring that the battery works reliably. When the battery 1 needs to be replaced, when the operator moves the battery 1 away from the battery placement platform 6, the external force applied by the battery disappears, the spring 5 is reset, and the force of the spring can push the bent portion 8 at the bottom of the metal curved connecting rod 4 to move upward, so that the metal curved connecting rod 4 is flipped outward relative to the battery placement platform 6, and the electrode replacement column 3 at the bottom of the battery replacement interface pressure plate 7 of the metal curved connecting rod 4 leaves the corresponding battery charging and discharging electrode. In this way, not only the electrode replacement column leaves the battery 1, but also the battery replacement interface pressure plate 7 leaves the battery 1, which will not constrain the battery 1 from above, making it easier to move the battery 1. Therefore, the structure of the utility model effectively simplifies vehicle battery replacement.

It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
