[0012] In a charging base station according to one embodiment of this application, the signal transmitting module includes an infrared transmitter and a first infrared lens, and the signal receiving module includes an infrared receiver and a second infrared lens.

The base station body is provided with a charging component for charging the self-moving device. The detection component is located on the base station body and is used to detect whether the self-moving device has moved to a preset position. When the self-moving device moves to the preset position, the charging component is in a powered-on state; when the self-moving device has not moved to the preset position, the charging component is in a powered-off state.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] like Figures 1 to 6As shown, this application provides a charging base station 100, including a base station body 10, a detection component 20, and a base for supporting a self-moving device 200. The detection component 20 is disposed on the base station body 10, and the base station body 10 is disposed on the base. A charging component 11 is disposed on the base station body 10. The charging component 11 is used to charge the self-moving device 200. The detection component 20 is used to detect whether the self-moving device 200 has moved to a preset position. When the self-moving device 200 moves to the preset position, the charging component 11 is in a powered-on state; when the self-moving device 200 has not moved to the preset position, the charging component 11 is in a powered-off state. This allows the detection component 20 to detect the positional relationship between the self-moving device 200 and the base station body 10. Charging is only performed after ensuring that the self-moving device 200 has moved into position and established an electrical connection with the charging component 11. This eliminates the risk of sparks caused by contact between the self-moving device 200 and the charging component 11 in a powered-on state, and improves the stability and safety of the self-moving device 200 and the charging base station 100 during charging.

[0038] By adopting the above technical solution, since this application first detects the position of the self-moving device 200 through the detection component 20, and then controls the charging component 11 to charge the self-moving device 200, the position detection of the self-moving device 200 takes precedence over the energization of the charging component 11 in the timing control. This effectively prevents sparks from occurring during the contact between the self-moving device 200 and the charging component 11, avoiding unstable charging due to poor contact, which could affect the charging efficiency of the device or even lead to safety accidents, such as the self-moving device 200 or the charging base station 100 being burned out. This makes the use of the self-moving device 200 and the charging base station 100 safer and extends their service life. In addition, since the charging component 11 is energized only when the self-moving device 200 moves to the preset position, it not only avoids the risk of the charging component 11 being exposed to electricity, but also reduces the risk of leakage in the charging base station 100, reducing the standby power consumption of the charging base station 100 and meeting the requirements of energy conservation and environmental protection.

[0039] It should be noted that the detection component 20 may be, but is not limited to, an infrared sensor, a photoelectric sensor, an ultrasonic sensor, an image sensor, and a Hall sensor, etc. Its main purpose is to detect whether the self-moving device 200 has moved to a preset position, and this application does not impose any restrictions.

[0040] In one alternative implementation, such as Figure 1 , Figure 4 and Figure 6As shown, the detection component 20 includes a signal transmitting module 22 and a signal receiving module 21 arranged opposite to each other. When the mobile device 200 does not move to the preset position, the signal transmitted by the signal transmitting module 22 is received by the signal receiving module 21, keeping the charging component 11 powered off. When the mobile device 200 moves to the preset position, the signal transmitted by the signal transmitting module 22 is blocked by the mobile device 200, triggering the charging component 11 to be powered on. This achieves precise control through non-contact signal detection. Compared with mechanical switches or contact sensors, the detection component 20 has no physical contact, which can avoid mechanical wear, improve the reliability of the detection component 20, extend its lifespan, and make it suitable for various harsh environments such as dust or humidity.

[0041] For example, the signal transmitting module 22 and the signal receiving module 21 are installed on opposite sides of the base station body 10 to form a stable signal transmission path. When the mobile device 200 enters the preset position, part of the structure of the mobile device 200 blocks the signal transmission between the signal transmitting module 22 and the signal receiving module 21, thereby triggering the charging component 11 to be powered on to charge the mobile device 200. This eliminates the risk of sparks caused by live contact by ensuring that the power is turned on only after the mobile device 200 has arrived in position, and solves the problems of arcing and short circuits caused by misaligned contact during the charging process of the existing mobile device 200. When there is no obstruction between the signal transmitting module 22 and the signal receiving module 21, the signal is continuously received. At this time, the charging component 11 is powered off, so that the charging base station 100 is powered off immediately when the mobile device 200 leaves the charging base station 100, avoiding the charging component 11 of the charging base station 100 from being powered on for a long time, thus preventing accidental contact and leakage, and reducing standby power consumption. Therefore, by adopting the above technical solution, not only can the risk of sparks occurring when the self-moving device 200 comes into contact with the charging component 11 which is in a powered state be avoided, but the automatic switching of the power on and off of the charging component 11 can also be realized, avoiding safety hazards and energy waste caused by long-term power supply.

[0042] In one alternative implementation, such as Figures 1 to 6As shown, the base station body 10 includes a first arm 12 and a second arm 13 arranged opposite to each other. One end of the first arm 12 and the second arm 13 forms an opening 14 for the mobile device 200 to move in. The signal transmitting module 22 and the signal receiving module 21 are respectively arranged on the first arm 12 and the second arm 13 to form a stable signal transmission path, so that the mobile device 200 can enter the physical guide channel formed by the first arm 12 and the second arm 13 from the opening 14, forcing the mobile device 200 to enter the charging area along a fixed path, ensuring the alignment accuracy of the charging contacts of the mobile device 200 and the base station charging component 11. When the mobile device 200 enters the physical guide channel and blocks the signal transmission path between the signal transmitting module 22 and the signal receiving module 21, the charging component 11 can be energized, so that the charging component 11 can charge the mobile device 200.

[0043] For example, the self-moving device 200 has a first charging contact 201, a second charging contact 202, and a signal blocking structure. The first charging contact 201 and the second charging contact 202 are located on both sides of the signal blocking structure. The spatial position of the signal blocking structure with the first charging contact 201 and the second charging contact 202 first satisfies the mechanical contact between the charging component 11 and the first charging contact 201 and the second charging contact 202, and then realizes the timing relationship of power-on. The first arm 12 and the second arm 13 form a physical guide channel with a V-shaped or U-shaped opening 14. The shape of the signal blocking structure is adapted to the shape of the physical guide channel. The signal transmitting module 22 and the signal receiving module 21 are respectively set on the first arm 12 and the second arm 13. The height of the optical axis center line of the signal transmitting module 22 and the signal receiving module 21 is not greater than the height of the signal blocking structure. This is so that when the self-moving device 200 enters the physical guide channel, the signal blocking structure can accurately block the signal, avoid premature or late triggering, and prevent the self-moving device 200 from excessively deviating through the mechanical limit of the physical guide channel. This can play a guiding role and ensure that the traveling direction of the self-moving device 200 is perpendicular to the axis of the signal hole.

[0044] In one alternative implementation, such as Figures 4 to 6 As shown, the first arm 12 is provided with a signal transmitting hole 131, and the second arm 13 is provided with a signal receiving hole 121. The signal transmitting hole 131 and the signal receiving hole 121 are used to constrain the divergence angle of the signal, avoid false triggering caused by signal scattering, realize optical-grade signal control, and achieve reliability comparable to high-end sensors at extremely low cost.

[0045] In an optional embodiment, both the signal transmitting aperture 131 and the signal receiving aperture 121 are narrow rectangular in shape. This prevents the transmission angle of the signal transmitting module 22 and / or the receiving angle of the signal receiving module 21 from being too large, thus failing to constrain the signal transmission path and affecting the signal judgment result of the charging base station 100. This utilizes shape engineering to transform a simple mechanical structure into a high-performance signal control system, combining low cost, high reliability, and easy mass production. Specifically, the signal transmitting module 22 transmits infrared signals to the signal receiving module 21, and the signal receiving module 21 receives the infrared signals emitted by the signal transmitting module 22. Due to light refraction and reflection, if the transmission and receiving angles are too large, the transmission and reception paths of the infrared signals may not be constrained to a straight line, thus affecting the signal judgment result of the charging base station 100.

[0046] In an optional embodiment, the signal transmitting module 22 includes an infrared transmitter 221 and a first infrared lens 222, and the signal receiving module 21 includes an infrared receiver 211 and a second infrared lens 212. The infrared signal emitted by the infrared transmitter 221 passes sequentially through the first infrared lens 222 and the second infrared lens 212 before being received by the infrared receiver 211. Both the first infrared lens 222 and the second infrared lens 212 have infrared-transmitting films, which not only achieve high transmittance of infrared signals but also reflect or absorb light of other wavelengths, preventing ambient light from affecting the data and improving the accuracy and reliability of signal detection.

[0047] In an optional embodiment, the charging assembly 11 includes a first charging terminal 111 and a second charging terminal 112. The first charging terminal 111 is disposed on the first support arm 12, and the second charging terminal 112 is disposed on the second support arm 13, so that when the mobile device 200 enters the physical guide channel formed by the first support arm 12 and the second support arm 13, optical alignment and electrical contact can be completed simultaneously to achieve precise timing matching and ensure charging safety and mechanical reliability.

[0048] In an optional embodiment, a first elastic member 15 is provided between the first charging terminal 111 and the first support arm 12, and the first charging terminal 111 can extend and retract relative to the first support arm 12. A second elastic member 16 is provided between the second charging terminal 112 and the second support arm 13, and the second charging terminal 112 can extend and retract relative to the second support arm 13. This allows the self-moving device 200 to maintain face-to-face contact with the first charging contact 201 and the second charging contact 202, thereby improving the reliability of the charging contact and the compatibility of the self-moving device 200.

[0049] In one optional embodiment, the base station body 10 includes a first side plate 10b, a second side plate 10c, and a base station body 10a mounted on a base. The base station body 10a has a first accommodating cavity and a second accommodating cavity formed on both sides. An infrared receiver 211 and a first elastic member 15 are installed in the accommodating cavity, and an infrared transmitter 221 and a second elastic member 16 are installed in the second accommodating cavity. The first side plate 10b covers the opening of the first accommodating cavity, and the second side plate 10c covers the opening of the second accommodating cavity.

[0050] In an optional embodiment, the signal transmitting module 22 and the first charging terminal 111 are sequentially arranged on the first support arm 12 from the end furthest from the opening 14 toward the end closest to the opening 14, and the signal receiving module 21 and the second charging terminal 112 are sequentially arranged on the second support arm 13. This ensures that when the self-moving device 200 enters the physical guide channel formed by the first support arm 12 and the second support arm 13, the first charging terminal 111 and the second charging terminal 112 first contact the first charging contact 201 and the second charging contact 202, and then block the signal transmission path between the signal transmitting module 22 and the signal receiving module 21, triggering an infrared signal, thereby enabling the self-moving device 200 to be charged.

[0051] In an alternative embodiment, the first arm 12 and the second arm 13 extend in a gradually expanding manner from the end away from the opening 14 toward the end closer to the opening 14, so as to improve the success rate and efficiency of automatic docking of the first charging contact 201 and the second charging contact 202 of the mobile device 200 with the first charging terminal 111 and the second charging terminal 112.

[0052] After adopting the above technical solutions, such as Figures 7 to 9As shown, the base station body 10 also includes a base station back 17, which is arranged opposite to the opening 14. The first arm 12 and the second arm 13 are connected to the two sides of the base station back 17. When the mobile device 200 enters the physical guide channel formed by the first arm 12 and the second arm 13 from the opening 14, and the distance between the mobile device 200 and the base station back 17 is greater than L1, the first charging contact 201 and the second charging contact 202 are separated from the first charging terminal 111 and the second charging terminal 112. The signal blocking structure is located on the side of the signal transmission path away from the base station back 17, that is, the infrared signal between the signal transmitting module 22 and the signal receiving module 21 is unblocked and the infrared signal is continuously received. At this time, the charging component 11 is powered off. When the distance between the mobile device 200 and the back of the base station 17 is L1 and L2, the first charging contact 201 and the second charging contact 202 are in contact with the first charging terminal 111 and the second charging terminal 112. The shielding structure is also located on the side of the signal transmission path away from the back of the base station 17, and the charging component 11 is in a power-off state. When the distance between the mobile device 200 and the back of the base station 17 is equal to L3, that is, when the mobile device 200 moves to the preset position, the blocking structure is located in the signal transmission path to block the signal transmission path between the signal transmitting module 22 and the signal receiving module 21. At this time, the charging component 11 is in the energized state, so that the spatial positions of the charging component 11 and the detection component 20 satisfy the time sequence relationship of mechanical contact first and then energization. This not only eliminates the risk of sparks caused by contact between the mobile device 200 and the charging component 11 in the energized state, but also improves the stability and safety of the mobile device 200 and the charging base station 100 during charging; it also enables precise control through non-contact signal detection. Compared with mechanical switches or contact sensors, the detection component 20 has no physical contact, which can avoid mechanical wear, improve the reliability of the detection component 20, and have a longer lifespan, making it suitable for various harsh environments such as dust or humidity.
