[0019] Compared with the current practice of moving cars to charging piles for charging, the battery automatic charging system provided by the present invention can directly retrieve charged batteries for replacement in cars, thus saving charging time and improving the utilization rate of the car. It is particularly suitable for environments that require a large amount of charging, and the number of docking devices, charging mechanisms and traction devices can be configured according to needs, making the device more widely applicable.

The present invention uses a traction mechanism to pull the battery and move the battery on the conveyor belt, which can effectively meet the needs of taking and placing heavy batteries.

[0026] The present invention will be further described below in conjunction with the accompanying drawings:

[0027] like Figure 1 As shown, it is a structural schematic diagram of a battery automatic charging system.

[0028] The automatic battery charging system of the present invention includes a controller and a conveying mechanism 1, the conveying mechanism 1 includes a mounting frame 11, a conveyor belt 15 in a closed ring shape is arranged on the mounting frame 11, a traction mechanism 2 is installed on the inner side of the conveyor belt 15, the traction mechanism 2 includes a plurality of mutually parallel horizontal cylinders 24, a traction claw 25 is arranged on the output shaft of the horizontal cylinder 24, and a docking device 13 is arranged at a position opposite to the horizontal cylinder 24 on the outer side of the mounting frame 11.

[0029] A charging mechanism 3 is installed on the other side of the mounting frame 11 opposite to the docking device 13, and the charging mechanism 3 includes a charging pile 31 opposite to the horizontal cylinder 24; a detection mechanism 4 is provided on the mounting frame 11 at a position adjacent to the charging pile 31 and the docking device 13, and the detection mechanism 4 includes a limit switch 41 and a ball screw motor 42, and the detection mechanism 4, the charging mechanism 3 and the traction mechanism 2 are electrically connected to the controller respectively.

[0030] Optionally, the controller is an STM32 microcontroller. The controller is set to control the corresponding actions of each component.

[0031] Preferably, a pressure sensor is provided on the docking device 13 so as to trigger the operation of the corresponding horizontal cylinder 24 when it is detected that a battery 5 is placed on the docking device 13 .

[0032] Specifically, Figure 3 As shown, the conveying mechanism 1 includes a lifting cylinder 21 fixedly arranged on the side of the mounting frame 11, the output end of the lifting cylinder 21 is connected to the traction seat 22, and the horizontal cylinder 21 is fixedly arranged on the traction seat 22. A longitudinal slide rail 12 is arranged on the side of the mounting frame 11, and a longitudinal slider 23 is arranged at the position where the traction seat 22 and the mounting frame 11 are connected.

[0033] The output shaft directions of the horizontal cylinder 24 opposite to the docking device 13 and the horizontal cylinder 24 opposite to the charging mechanism 3 are opposite. The number of the horizontal cylinder 24, the docking device 13 and the charging mechanism 3 can be set according to actual needs to ensure the charging efficiency and the utilization rate of the device.

[0034] like Figure 2 As shown, a charging socket 33 is provided on the charging pile 31, and a horizontal slide rail 32 is provided on the charging mechanism 3 adjacent to the charging pile 31. A pressure sensor is provided on the charging pile 31 at the upper side of the charging socket 33, and the pressure sensor is electrically connected to the controller to detect whether the battery 5 is in place.

[0035] The detection mechanism 4 is located on the same side of the charging mechanism 3 and the docking device 13 relative to the running direction of the conveyor belt 15; the limit switch 41 is located between the ball screw motor 42 and the adjacent charging mechanism 3 and the docking device 13, so that after the limit switch 41 detects the battery 5, the controller drives the ball screw motor to work to block the battery 5, thereby limiting its position and facilitating the operation of the traction mechanism 2.

[0036] The automatic battery charging system also includes a battery 5, such as Figure 4 , which are schematic diagrams of the structure of the battery 5 at two angles. A tray 14 is provided below the battery 5 to hold the battery 5, so that its position is higher than the conveyor belt 15 and is at the same height as the bottom surface of the docking device 13 and the charging mechanism 3 to facilitate transportation.

[0037] A charging plug 51 that cooperates with the charging socket 33 is provided at one end of the battery 5 , and a connecting bent plate 52 that cooperates with the traction claw 25 is provided at the other end. Horizontal sliders 53 that cooperate with the horizontal slide rails 32 are provided at the lower parts of both sides of the battery 5 .

[0038] Preferably, the connecting bent plate 52 is L-shaped and the traction claw 25 is concave, so that the traction claw 25 is effectively connected to the connecting bent plate 52 to achieve both pulling and pushing actions.

[0039] The following is a description of the specific working principle of this solution:

[0040] When the battery power of the car is too low, the car is driven to the position of the docking device 13 of the system, so that the battery 5 is connected to the docking device 13, and the pressure sensor on the docking device 13 triggers the operation of the relative traction mechanism 2, and the traction seat 22 is driven to move up by the lifting cylinder 21, and then the horizontal cylinder 24 drives the traction claw 25 to extend to the set position, and then descends until the traction claw 25 cooperates with the connecting bent plate 52, so that the horizontal cylinder 24 is recovered, and the battery 5 is dragged to the tray 14 of the conveyor belt 15, and the conveyor belt 15 drives the battery 5 to move.

[0041] When the battery 5 moves to the corresponding position of the charging mechanism 3, the limit switch 41 is triggered first, and then the controller determines whether there is a battery 5 being charged on the charging mechanism 3 according to the detection result of the corresponding pressure sensor on the charging mechanism 3. If the pressure sensor detects the existence of pressure, it means that a battery 5 is being charged, and the battery 5 continues to move to the next charging mechanism 3 with the conveyor belt 15; if it is detected that there is no battery 5 on the charging mechanism 3, the controller drives the ball screw motor 42 to work, so that the ball screw is extended to block the battery 5, and the traction seat 22 on the traction mechanism 2 pushes the battery 5 forward, so that the horizontal slider 53 on the battery 5 cooperates with the horizontal slider 32 until the charging plug 51 cooperates with the charging socket 33, and triggers the monitoring of the pressure sensor to start charging. At this time, the traction mechanism 2 is separated from the battery 5 and returns to the original position.

[0042] When charging is completed, the traction mechanism 2 drags the battery 5 back to the tray 14 of the conveyor belt 15 until the docking device 13 is located. The limit switch 41 and the ball screw motor 42 at the docking device 13 limit the movement of the charged battery 5. The traction mechanism 2 pushes the charged battery 5 onto the docking device 13 so that it can be directly inserted into the car.

[0043] The above describes the specific embodiments of the present invention to facilitate those skilled in the art to understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations using the concept of the present invention are protected.
