The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

Please refer to FIG. 1 . An embodiment of the present invention provides a mobile system 30 . The mobile system 30 may include a charging device 10 and a self-moving device 20 . The charging device 10 may be electrically connected to the self-moving device 20 , so that the charging device 10 may charge the mobile device.

The self-moving device 20 may include a control component and a drive module, the control component may include components such as a circuit board, and the control component may control the movement of the drive module. For example, the drive module may include a drive wheel, and the number of the drive wheels may be multiple, and the multiple drive wheels may be arranged at the bottom of the self-moving device 20 to achieve the movement of the self-moving device 20. The drive module may also include a crawler track, and the crawler track may be arranged at the bottom of the self-moving device 20 to achieve the steering of the self-moving device 20.

The self-moving device 20 may also include an ultrasonic ranging sensor or a laser radar or an infrared ranging sensor or a visual sensor for identifying obstacles. The self-moving device 20 has a path planning function (i.e., obstacle handling capability). For small obstacles, the self-moving device 20 can automatically cross. For medium and large obstacles, the self-moving device 20 can avoid them in time and clear the snow around the obstacles to the maximum extent. For example, the transmitter of the ultrasonic ranging sensor of the self-moving device 20 emits an ultrasonic wave, and the ultrasonic wave meets and is reflected by the obstacle. The receiver of the ultrasonic ranging sensor can measure the distance from the obstacle to the self-moving device 20 based on the time difference of receiving the ultrasonic wave, so that the self-moving device 20 can make plans to avoid obstacles in advance, avoid collisions with obstacles, and effectively improve the safety performance of the self-moving device 20.

The self-moving device 20 can be equipped with devices such as a snow removal device, a leaf blowing device or a weeding device, so that the snow removal device, the leaf blowing device or the weeding device can operate in a preset area, thereby helping to improve the practicality of the self-moving device 20.

The self-moving device 20 may further include a battery, which may provide power for the self-moving device 20 .

Please refer to FIG. 2 and FIG. 3 . The self-mobile device 20 may further include a receiving-end electrode assembly 800 . The receiving-end electrode assembly 800 may be electrically connected to a battery and a charging device 10 , so that the charging device 10 may charge the battery in the self-mobile device 20 .

The receiving-end electrode assembly 800 may include a receiving-end electrode 810 , which may be electrically connected to a battery and a charging device 10 , so that the charging device 10 may charge the battery in the mobile device 20 .

The receiving-end electrode assembly 800 may further include a magnetic member 820. When the receiving-end electrode assembly 800 is normally connected to the charging device 10, the charging device 10 may identify the magnetic member 820, so that the charging device 10 may start charging the battery of the mobile device 20. There are many options for the magnetic member 820. For example, the magnetic member 820 may be a magnet ring or a magnet block; for another example, the magnetic member 820 may be a magnet ring or a magnet block composed of a plurality of magnet sheets.

The specific structure of the charging device 10 refers to the following embodiments. Since the mobile system 30 adopts all the technical solutions of all the following embodiments, it has at least all the beneficial effects brought by the technical solutions of the following embodiments, which will not be described one by one here.

1 , the present invention also provides a charging device 10, which can be applied to a mobile system 30. In the following embodiments, the application of the charging device 10 to the mobile system 30 is mainly used as an example for description, and other situations requiring the charging device 10 can be implemented with reference.

Please refer to Figures 1 to 7. The charging device 10 may include a transmitting end electrode assembly 100, an electric push rod 200 and a controller 300. The transmitting end electrode assembly 100 may include a transmitting end mounting component 110 and a magnetic sensor 120. The magnetic sensor 120 may be installed on the transmitting end mounting component 110. The magnetic sensor 120 may be used to sense the magnetic component 820 of the receiving end electrode assembly 800 of the self-moving device 20. The output shaft 210 of the electric push rod 200 is connected to the transmitting end mounting component 110 to drive the transmitting end electrode assembly 100 to move. The controller 300 may be electrically connected to the electric push rod 200 and the magnetic sensor 120. When the charging device 10 is positioned and connected with the self-moving device 20, the controller 300 can control the movement of the output shaft 210 of the electric push rod 200 according to the induction signal of the magnetic sensor 120 to the magnetic component.

In this way, the output shaft 210 of the electric push rod 200 can drive the transmitting end electrode assembly 100 to be electrically connected with the receiving end electrode assembly 800 of the self-moving device 20. After the positioning and connection between the charging device 10 and the self-moving device 20 are completed, the controller 300 can control the movement of the output shaft 210 of the electric push rod 200 according to the sensing signal of the magnetic sensor 120 to the magnetic part 820, so that the output shaft 210 of the electric push rod 200 can push the transmitting end electrode assembly 100 to a suitable position, thereby facilitating the precise control of the moving stroke of the output shaft 210 of the electric push rod 200, and further helping the transmitting end electrode assembly 100 to have good contact with the receiving end electrode assembly 800 of the self-moving device 20, so that the charging device 10 can stably charge the self-moving device 20.

In addition, the low temperature environment has less impact on the magnetic component 820 and the magnetic sensor 120. The magnetic sensor 120 can also have higher sensitivity and good anti-interference ability in the low temperature environment, so that the magnetic sensor 120 can work stably in the low temperature environment, thereby improving the reliability and stability of the mobile system 30.

It is understandable that the magnetic member 820 can be pre-set at a suitable position of the receiving-end electrode assembly 800 of the mobile device 20 so that the magnetic sensor 120 can sense the position of the magnetic member 820 .

In some embodiments, the receiving-end electrode assembly 800 may further include a receiving-end mounting component 830 , and the magnetic component 820 may be mounted on a surface of the receiving-end mounting component 830 , thereby facilitating the magnetic sensor 120 to quickly sense the magnetic component 820 .

In some embodiments, the receiving end electrode assembly 800 may further include a receiving end electrode, the receiving end electrode 810 may be mounted on the receiving end mounting component 830, and the magnetic member 820 may be disposed adjacent to the receiving end electrode 810. Specifically, the magnetic member 820 is disposed adjacent to the receiving end electrode 810, and when the magnetic sensor 120 senses the magnetic member 820, the transmitting end electrode assembly 100 may be connected to the receiving end electrode 810 quickly and correspondingly.

The self-moving device 20 and the charging device 10 can use the RTK positioning technology to make the self-moving device 20 stay next to the charging device 10 so that the charging device 10 can charge the self-moving device 20 more accurately.

When the self-moving device 20 needs to be charged, the self-moving device 20 and the charging device 10 use RTK positioning technology to make the self-moving device 20 stay next to the charging device 20, and the charging device 10 can establish a connection with the self-moving device 20 so that the controller 300 can confirm that the self-moving device 20 has been accurately moved to the side of the charging device 10.

Among them, the charging device 10 and the self-moving device 20 can achieve the connection between the two devices through radio waves, infrared rays, or magnetic induction technologies. For example, the charging device 10 can be connected to the self-moving device 20 through a magnetic induction magnetic field signal, such as a magnetic induction sensor is set on one of the self-moving device 20 and the charging device 10, and a positioning coil for the magnetic induction sensor to sense is set on the other of the charging device 10 and the self-moving device 20, so that the controller 300 can confirm that the self-moving device 20 has been accurately moved to the side of the charging device 10 after the positioning connection between the charging device 10 and the self-moving device 20 is completed; for example, the charging device 10 can be connected to the self-moving device 20 through infrared rays, and infrared sensors are set on both the self-moving device 20 and the charging device 10, and the infrared sensor in the self-moving device 20 can receive the infrared rays emitted by the infrared sensor in the charging device 10 to achieve positioning connection.

When the controller 300 has confirmed that the self-moving device 20 has accurately moved to the side of the charging device 10, the controller 300 can control the output shaft 210 of the electric push rod 200 to move, and at this time, the output shaft 210 of the electric push rod 200 of the charging device 10 can drive the transmitting end electrode assembly 100 to be electrically connected with the receiving end electrode assembly 800 of the self-moving device 20. Since the magnetic sensor 120 detects different parameters such as the magnetic field strength or magnetic flux of the magnetic part 820 in the process of following the movement of the electric push rod 200, for example, when the magnetic sensor 120 gradually approaches the magnetic part 820, the magnetic field strength of the magnetic part 820 detected by the magnetic sensor 120 gradually increases, so that when the magnetic sensor 120 is in different positions, the parameters such as the magnetic field strength or magnetic flux of the magnetic part 820 sensed by the magnetic sensor 120 are different. Therefore, the controller 300 can control the movement of the output shaft 210 of the electric push rod 200 according to the size of parameters such as the magnetic field strength or magnetic flux of the magnetic part 820 sensed by the magnetic sensor 120. For example, the controller 300 can compare the size of parameters such as the magnetic field strength or magnetic flux stored in advance with the size of parameters such as the magnetic field strength or magnetic flux of the magnetic part 820 sensed by the magnetic sensor 120, so that the controller 300 controls the movement of the output shaft 210 of the electric push rod 200 when the conditions are met, which helps to ensure good contact between the transmitting end electrode assembly 100 and the receiving end electrode assembly 800 of the self-moving device 20.

The controller 300 may be a central control unit; or the controller 300 may include a plurality of sub-control units. The controller 300 includes components such as a circuit board.

The magnetic sensor 120 can detect the magnetic field by utilizing the magnetic field sensitivity characteristics of magnetic sensitive materials (such as magnetoresistance, Hall elements, etc.). When the measured magnetic field of the magnetic component 820 acts on the magnetic sensor 120, it will cause changes in the physical quantity inside the magnetic sensitive material of the magnetic sensor 120, such as changes in resistance, voltage or current, and then convert it into a measurable electrical signal, that is, an induction signal. Among them, the magnetic sensor 120 can have a variety of options, for example, the magnetic sensor 120 can be a Hall effect sensor; for another example, the magnetic sensor 120 can be a magnetoresistive sensor; for another example, the magnetic sensor 120 can be a magnetic induction sensor.

Referring to FIG. 3 to FIG. 7 , in some embodiments, the transmitting end electrode assembly 100 may further include a transmitting end electrode 130, which may be mounted on the transmitting end mounting component 110. For example, the transmitting end electrode 130 may be fixed to the transmitting end mounting component 110 by plugging or threading. The transmitting end electrode 130 may be electrically connected to an external power source to provide power to the charging device 10, so that the charging device 10 may charge the self-moving device 20. When the transmitting end electrode assembly 100 is electrically connected to the receiving end electrode assembly 800 of the self-moving device 20, the transmitting end electrode 130 is electrically connected to the receiving end electrode 810.

Please refer to Figures 3 and 7. The magnetic sensor 120 can be set adjacent to the transmitting end electrode 130. When the transmitting end electrode 130 is in good contact with the receiving end electrode 810, the magnetic sensor 120 can quickly and accurately sense the magnetic member 820, so that the controller 300 can promptly control the output shaft 210 of the electric push rod 200 to stop moving, thereby helping to reduce the risk of the output shaft 210 of the electric push rod 200 continuing to move and damaging other components when the transmitting end electrode 130 is in good contact with the receiving end electrode 810.

Please refer to Figures 5 to 8. In some embodiments, the transmitting end electrode component 110 may also include a sensor mounting member 140 connected thereto. The sensor mounting member 140 may be provided with a mounting groove 141. The magnetic sensor 120 may be mounted in the mounting groove 141. For example, the magnetic sensor 120 may be bonded to the mounting groove 141 by an adhesive. For another example, the magnetic sensor 120 may be limited in the mounting groove 141 by a sheet metal part. In this way, the magnetic sensor 120 is mounted in the mounting groove 141, which may make the assembly of the transmitting end electrode assembly 100 more compact, and also facilitate the installation of the magnetic sensor 120, with a simple structure and convenient operation. In addition, when the electric push rod 200 drives the transmitting end electrode assembly 100 to move, it helps to reduce the risk of direct collision between the magnetic sensor 120 and other components, thereby facilitating the protection of the magnetic sensor 120.

Please refer to FIG. 1 and FIG. 4 . In some embodiments, the charging device 10 may further include a housing 400 . The electric push rod 200 may be installed in the housing 400 so as to protect the electric push rod 200 .

Please refer to FIG. 9 . The charging device 10 may further include a guide component 500. The guide component 500 may be located in the housing 400. The guide component 500 may include a guide sleeve 510 and a guide shaft 520 slidably located in the guide sleeve 510. The guide sleeve 510 may be connected to the housing 400. For example, the guide sleeve 510 may be fixedly connected to the housing 400 by welding. For another example, the guide sleeve 510 may be relatively fixed to the housing 400 by a flange. The end of the guide shaft 520 may be connected to the transmitting end mounting component 110. Specifically, one end of the guide shaft 520 extending from the guide sleeve 510 is connected to the transmitting end mounting component 110. The sliding direction of the guide shaft 520 is parallel to the moving direction of the output shaft 210 of the electric push rod 200. Since the end of the guide shaft 520 and the output shaft 210 of the electric push rod 200 are both connected to the transmitting end mounting component 110, when the output shaft 210 of the electric push rod 200 moves, the output shaft 210 of the electric push rod 200 can drive the guide shaft 520 to slide in the guide sleeve 510, thereby helping the guide component 500 to guide the moving direction of the output shaft 210 of the electric push rod 200, so that the output shaft 210 of the electric push rod 200 can be driven to move stably along a preset direction.

In some embodiments, there may be multiple guide components 500, for example, there may be two, three or four guide components 500. Multiple guide components 500 are more helpful in guiding the moving direction of the output shaft 210 of the electric push rod 200, so that the output shaft 210 of the electric push rod 200 can move more stably along the set direction.

Please refer to FIG. 4 and FIG. 9 . In some embodiments, the guide component 500 may further include a ball sleeve 530 . A plurality of balls are disposed on the outer circumference of the ball sleeve 530 . Two adjacent balls may be arranged at intervals.

The ball sleeve 530 can be sleeved on the outer circumference of the guide shaft 520, so that the ball sleeve 530 can be located between the guide sleeve 510 and the guide shaft 520. The ball sleeve 530 helps to reduce the friction between the guide sleeve 510 and the guide shaft 520, so that the guide shaft 520 can slide smoothly in the guide sleeve 510. In addition, the ball sleeve 530 is located between the guide sleeve 510 and the guide shaft 520, and the friction between the guide sleeve 510 and the guide shaft 520 is small, which helps to reduce the risk of the guide shaft 520 sliding in the guide sleeve 510 and getting stuck. Moreover, the friction between the guide sleeve 510 and the guide shaft 520 is small, which helps to extend the service life of the guide sleeve 510 and the guide shaft 520.

In some embodiments, the guide component 500 may further include a first stopper 540 and a second stopper 550. The first stopper 540 may be located at one end of the guide shaft 520 away from the transmitting end mounting component 110. The second stopper 550 may be provided with a mounting through hole 551 (see FIG. 10). The guide shaft 520 may be inserted through the mounting through hole 551. The ball bushing 530 may be located between the first stopper 540 and the second stopper 550. Specifically, the first stopper 540 may be a stopper plate or a stopper block. The first stopper 540 may be connected to the end of the guide shaft 520 away from the transmitting end mounting component 110, and the outer diameter of the first stopper 540 is greater than the outer diameter of the guide shaft 520. The second stopper 550 may be a silicone stopper sleeve or a rubber stopper sleeve. The second stopper 550 may be firmly sleeved on the guide shaft 520 and is not easy to move. In this way, the first stopper 540 and the second stopper 550 can limit the ball sleeve 530 on the guide shaft 520, thereby helping to reduce the risk of the ball sleeve 530 falling off the guide shaft 520. In addition, the first stopper 540 and the second stopper 550 can limit the ball sleeve 530 to the end of the guide shaft 520 away from the launch end mounting component 110. When the end of the guide shaft 520 away from the launch end mounting component 110 is located in the guide sleeve 510, the ball sleeve 530 can also reduce the friction between the guide shaft 520 located in the guide sleeve 510 and the guide sleeve 510, so that the guide shaft 520 can slide relatively smoothly in the guide sleeve 510.

Please refer to FIG. 4 , in some embodiments, the charging device 10 may further include a support plate 600 located in the housing 400, and the electric push rod 200 and the guide sleeve 510 are both mounted on the support plate 600. Specifically, the support plate 600 may be installed at a suitable position, for example, the support plate 600 may be located in the middle of the housing 400, so that when the center of gravity of the electric push rod 200 and the guide sleeve 510 changes, the support plate 600 may play a supporting role, so that the electric push rod 200 and the guide sleeve 510 may work stably.

Among them, corresponding snap-in notches can be provided at the connection between the support plate 600 and the electric push rod 200 and the guide sleeve 510, so that the support plate 600 can be snap-fitted with the electric push rod 200 and the guide sleeve 510 respectively, which helps to improve the stability and reliability of the connection between the support plate 600 and the electric push rod 200 and the guide sleeve 510.

In some embodiments, the charging device 10 may further include a housing 400, the housing 400 may be provided with a storage space 410, and the output shaft 210 of the electric push rod 200 is connected to the transmitting end mounting component 110 to drive the transmitting end electrode assembly 100 to be stored or extended in the storage space 410. Specifically, as shown in FIG1, when the transmitting end electrode assembly 100 of the charging device 10 is connected to the receiving end electrode assembly 800 of the self-moving device 20, the output shaft 210 of the electric push rod 200 can drive the transmitting end electrode assembly 100 to extend out of the storage space 410, so that the transmitting end electrode assembly 100 can be electrically connected to the receiving end electrode assembly 800; as shown in FIG9, when the transmitting end electrode assembly 100 of the charging device 10 is not connected to the receiving end electrode assembly 800 of the self-moving device 20, the output shaft 210 of the electric push rod 200 can drive the transmitting end electrode assembly 100 to be stored in the storage space 410, so as to protect the transmitting end electrode assembly 100.

Please refer to FIG. 1 , FIG. 2 , FIG. 4 and FIG. 11 . In some embodiments, the housing 400 is provided with a through hole 420, and the through hole 420 can be connected to the accommodating space 410. The charging device 10 can also include a shielding door 700, and the shielding door 700 can be movably connected to the housing 400 to shield or open the through hole 420. For example, the shielding door 700 can be rotatably connected to the housing 400 through a hinge or a latch, so that the shielding door 700 can shield or open the through hole 420; for another example, one of the shielding door 700 and the housing 400 can be provided with a slide rail, and the other of the shielding door 700 and the housing 400 can be provided with a slider, so that the shielding door 700 can shield or open the through hole 420.
