Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a quick battery replacement mechanism for new energy vehicles includes a base plate 1. A ramp 2 is installed on one end of the top side of the base plate 1. Two vehicle rails 3 are symmetrically arranged on the top side of the ramp 2. One of the vehicle rails 3 has a rectangular groove 4 inside. A circular groove 5 is formed inside the ramp 2 on the bottom side of the rectangular groove 4. A movable rod 6 is movably installed inside the circular groove 5. A limit block 7 is installed at the bottom end of the movable rod 6. A spring 8 is fixed between the limit block 7 and the ramp 2. The spring 8 is sleeved on the outside of the movable rod 6. One end of the movable rod 6 is installed inside the rectangular groove 4. Mounting frame 9, with rotating rollers 10 mounted between its two sides via pins, electrode plate 11 mounted on the bottom side of mounting frame 9, electrode sheet 12 mounted on the inner wall of the bottom side of rectangular groove 4 directly below electrode plate 11, mounting frame 13 through the middle of base plate 1, top side of mounting frame 13 being on the same horizontal line as the highest point of ramp 2, one end of track 3 passing through the top side of mounting frame 13 and extending to one end of mounting frame 13, through groove 14 opening at the center of mounting frame 13, and light strip 15 mounted on the four side walls of through groove 14;

[0024] A fixing frame 26 is mounted on the top side of the mounting frame 13, and a warning light 27 is mounted on the top side of the fixing frame 26. A controller 28 is assembled at the top edge of the base plate 1. The controller 28 is electrically connected to the electrode plate 11, electrode sheet 12, light strip 15, and warning light 27, and is used for signal transmission to the electrode plate 11 and electrode sheet 12, as well as operation control of the light strip 15 and warning light 27. During operation, in practical applications, when the driver drives the vehicle into the battery replacement area, it is difficult to accurately align the battery in the vehicle body with the battery replacement position, which increases the time the vehicle spends in the replacement area and reduces the battery replacement speed. When the vehicle body drives into the mounting frame 13 area along the track 3 on the ramp 2, the wheels will contact the roller 10 inside the track 3. As the wheels continue to move forward, the vehicle... The wheel presses down on the rotating roller 10. Due to the pressure of the wheel, the mounting bracket 9 moves downward along the movable rod 6, which stretches the spring 8. At the same time, the electrode plate 11 gradually approaches and contacts the electrode piece 12, forming a closed circuit and generating an electrical signal. This electrical signal is transmitted to the controller 28. After receiving the electrical signal from the electrode plate 11 and the electrode piece 12, the controller 28 turns on the light strip 15 and the warning light 27. The light strip 15 illuminates to provide visual guidance for the driver, enabling him to accurately locate the battery in the vehicle body at the battery replacement position for quick battery replacement. The warning light 27 illuminates to indicate that the vehicle has entered the battery replacement preparation state. The contact between the electrode plate 11 and the electrode piece 12 is only responsible for the operation of turning on the light strip 15 and the warning light 27. The specific model of the controller 28 is eval-m1.

[0025] Please see Figure 1 , 2 As shown in Figure 5, a rotating shaft 16 is rotatably mounted inside the bottom side of the mounting frame 13, a support plate 17 is mounted on the top of the rotating shaft 16, two cylinders 18 are symmetrically mounted on the top side of the support plate 17, and a support plate 19 is mounted on the working end of the cylinder 18. One of the support plates 19 is located directly below the through groove 14, and a material inlet 20 is opened on one side of the mounting frame 13.

[0026] A driven gear 21 is installed at the middle end of the rotating shaft 16, a servo motor 22 is installed on the bottom inner wall of the mounting frame 13, and a driving gear 23 is installed at the output end of the servo motor 22. The driving gear 23 meshes with the driven gear 21, and the radius of the driven gear 21 is larger than the radius of the driving gear 23.

[0027] The mounting frame 13 has an arc-shaped groove 24 on its bottom inner wall, with an arc of 180 degrees. A sliding rod 25 is mounted on the bottom side of the driven gear 21, and the bottom end of the sliding rod 25 is slidably mounted inside the arc-shaped groove 24. During operation, in the field of new energy vehicles, with increased usage time and charging / discharging cycles, irreversible reactions occur in the chemical substances inside the battery, leading to a gradual decrease in battery capacity. Therefore, battery replacement is necessary to ensure normal vehicle operation. Thus, a quick battery replacement mechanism for new energy vehicles is required. After the vehicle stops, the cylinder 18 can adjust the height of the support plate 19 as needed to facilitate receiving the old battery and removing it from the vehicle body. Then, the actuating end of the cylinder 18 shortens, pulling the old battery back into the mounting frame 13. The servo motor 22 is started, and its output end drives the drive gear 23 to rotate. Because the drive gear 23... The driven gear 21 meshes with the driven gear 21, and the radius of the driven gear 21 is larger than the radius of the driving gear 23. The driven gear 21 will rotate at a slower speed, driving the rotating shaft 16 to rotate. The support plate 17 at the top of the rotating shaft 16 will rotate accordingly, and the tray 19 will also rotate. The tray 19 containing the new battery rotates to the bottom of the through slot 14. Then, the actuating end of the control cylinder 18 extends, pushing the new battery to the battery installation position in the vehicle body, completing the battery replacement operation. The replaced battery and the new battery go out and enter from the feed port 20 respectively. Since the arc of the arc slot 24 is 180 degrees, the slide bar 25 can only slide in the arc slot 24, ensuring that the driven gear 21 drives the support plate 17 to rotate 180 degrees, so that the two trays 19 can be accurately positioned directly below the through slot 14, avoiding the trays 19 from being offset from the battery installation position in the vehicle body, and ensuring the accuracy and efficiency of the battery replacement operation.

[0028] After a series of replacement operations are completed, the controller 28 will detect the corresponding status change and turn off the control light strip 15 and warning light 27. The vehicle owner can then drive the vehicle out of the replacement area to complete the entire quick battery replacement process.

[0029] Working principle: When the vehicle body enters the mounting frame 13 area along the track 3 on the ramp 2, the wheel will contact the rotating roller 10 inside the track 3. As the wheel continues to move forward, the wheel will press down on the rotating roller 10. Due to the pressure of the wheel, the mounting frame 9 will move down along the movable rod 6, which will stretch the spring 8. At the same time, the electrode plate 11 will gradually approach and contact the electrode piece 12, forming a closed circuit and generating an electrical signal. This electrical signal is transmitted to the controller 28. After receiving the electrical signal from the electrode plate 11 and the electrode piece 12, the controller 28 will turn on the light strip 15 and the warning light 27. The light strip 15 lights up to provide visual guidance for the driver, enabling him to accurately position the battery in the vehicle body at the battery replacement position for quick battery replacement. The warning light 27 lights up to indicate that the vehicle has entered the battery replacement preparation state. The contact between the electrode plate 11 and the electrode piece 12 is only responsible for the operation of turning on the light strip 15 and the warning light 27.

[0030] After the vehicle comes to a complete stop, cylinder 18 can adjust the height of tray 19 as needed to facilitate the receipt of old batteries. The old batteries are then removed from the vehicle body. Subsequently, the actuating end of cylinder 18 shortens, pulling the old batteries back into the mounting frame 13. The servo motor 22 is then activated, its output driving the drive gear 23. Since the drive gear 23 meshes with the driven gear 21, and the radius of the driven gear 21 is larger than that of the drive gear 23, the driven gear 21 rotates at a slower speed. The driven gear 21 drives the rotating shaft 16 to rotate, causing the support plate 17 at the top of the rotating shaft 16 to rotate accordingly. The tray 19 also rotates, holding the batteries. The tray 19 with the new battery rotates to be directly below the through slot 14. Then, the actuating end of the control cylinder 18 extends, pushing the new battery to the battery installation position inside the vehicle body, completing the battery replacement operation. The replaced battery and the new battery exit and enter through the feed port 20 respectively. Since the arc of the arc slot 24 is 180 degrees, the slide bar 25 can only slide within the arc slot 24, ensuring that the driven gear 21 drives the support plate 17 to rotate 180 degrees, so that the two trays 19 can be accurately positioned directly below the through slot 14, avoiding the trays 19 from being offset from the battery installation position in the vehicle body, and ensuring the accuracy and efficiency of the battery replacement operation.

[0031] After a series of replacement operations are completed, the controller 28 will detect the corresponding status change and turn off the control light strip 15 and warning light 27. The vehicle owner can then drive the vehicle out of the replacement area to complete the entire quick battery replacement process.
