[0045] The applicant noted that during the charging process, the charger usually has a charging lock function to prevent motor or other safety problems caused by accidental power failure or unplugging the charger during the charging process. Usually, the lock can only be released when the electrical connection between the charger and the battery is disconnected. However, due to the large number of mobile devices among the existing types of electrical equipment, such as robot dogs, robots, sweepers, and electric vehicles, which can achieve autonomous movement, when charging such equipment, locking the charger with the charging device will cause problems such as dragging wires and causing damage to the plug or even battery failure. In particular, when the charger is plugged in and locked, but there is a power outage or it is fully charged, the presence of the charger cannot be detected through the charging current or the charging status detection of the charging chip, which can easily cause problems such as dragging wires and plug damage.

[0046] Based on the above considerations, a charging device is provided to improve the reliability of charger in-place detection. Figure 1 , Figure 2 and Figure 5 As shown, Figure 1 The structure diagram of the charging socket in one embodiment of the utility model is shown. Figure 2The figure shows a connection diagram of a charging socket and a charging plug in an embodiment of the utility model. The charging socket provided in an embodiment of the utility model includes a first body 10, a charging interface 102 and a detection component 104. The charging interface 102 is arranged on the first body 10, and the charging interface 102 is used to connect with a charging connector 204 (mentioned later); the detection component 104 is arranged on the first body 10 and is spaced apart from the charging interface 102. The detection component 104 is used to detect whether the plug connector 20 or the protective cover is in place. When the detection component 104 detects that it is triggered by the plug connector 20 or the protective cover, the detection component 104 detects that the plug connector 20 or the protective cover is in place.

[0047] Specifically, during charging, Figure 5 As shown, the charging interface 102 is plugged into the charging connector 204, and the power current charges the charging target via the charging connector 204. When the charging connector 204 is plugged into the charging interface 102, the trigger detection component 104 detects the in-place state of the plug connector 20. When the detection component 104 is triggered by the plug connector 20, the detection component 104 determines that the plug connector 20 is in the in-place state. The in-place state of the plug connector 20 is that the plug connector 20 and the charging socket are in a plug-in connection state.

[0048] For example, when the charging socket is applied to a mobile power-consuming device such as a robot dog, a sweeper, or an electric vehicle, the charging socket is set on the power-consuming device such as the robot dog. When charging, the charging connector is plugged into the charging socket, triggering the detection component 104 to detect the in-place state of the plug connector 20; when the charging device is detected to be in-place, the movement of the mobile power-consuming device such as the robot dog is restricted. When the power-consuming device is in a state where the charging current is almost zero, that is, when the power is off or the power-consuming device is fully charged, the charging device does not perform the charging action but is in-place, and the movement state of the power-consuming device is also restricted.

[0049] Optionally, the component that triggers the detection component 104 is a protective cover; a protective cover is provided on the charging socket, and the protective cover is also provided in an in-place state and an out-of-place state; wherein the in-place state of the protective cover is when the protective cover is open, and the out-of-place state of the protective cover is when the protective cover is closed. Before charging, the protective cover is in an out-of-place state, at which time the detection component 104 detects that the protective cover is in an out-of-place state, and does not restrict the movement of the electrical device; when charging is required, the protective cover on the charging socket is opened to expose the charging interface 102 provided on the first body 10, at which time the detection component 104 detects that the protective cover is in a in-place state, and restricts the movement of the electrical device.

[0050] The trigger detection component 104 can also be triggered by the plug connector and the protective cover. When either or both of the plug connector 20 and the protective cover are in the in-place state, the detection component 104 determines that they are in the in-place state and limits the movement of the electrical device.

[0051] When the plug connector 20 and the protective cover are in place, the detection component 104 restricts the movement of the electrical device. When the plug connector 20 and the protective cover are not in place, the detection component 104 keeps monitoring the state of the charging socket. The detection and judgment of the detection component 104 only judges the state of the plug connector or the protective cover, and is not affected by whether the charging socket is in a charging state; that is, it avoids misjudging that charging is not being performed when the plug connector is connected to the charging socket but no charging action is performed (power outage or full charge).

[0052] In this embodiment, the plug connector and the protective cover are detected by the detection component 104 to obtain the position status of the charging connector and the charging interface. In special circumstances such as power outages and full-charge charging, it can avoid misjudging that the charger is not plugged in, so that the charging status can be judged comprehensively and in multiple scenarios, thereby improving the reliability and compatibility of the detection of the charging connector and the charging interface in place. When it is detected that the charging connector and the charging interface are in place, the movement of the electrical device or the movement range of the limiter can be restricted to avoid dragging the wires to cause damage to the plug or even cause a safety accident, thereby improving the safety of the charging process.

[0053] Please continue reading Figure 1 Combined with Figure 3 , Figure 3 The schematic diagram of the structure of the detection component in an embodiment of the utility model is shown. In some embodiments, the detection component 104 includes a sensor 106 and a controller 108. The sensor 106 is spaced apart from the charging interface 102 and is used to sense whether the plug connector 20 or the protective cover is in place; the controller 108 is electrically connected to the sensor 106.

[0054] Exemplarily, the sensing element 106 is a micro switch, and the micro switch is spaced apart from the charging interface 102; when the plug connector 20 or the protective cover is in place, the micro switch is triggered by the plug connector 20 or the protective cover, and the first body 10 is in a plugged state; when the micro switch is in a disconnected state, the micro switch is separated from the plug connector 20 or the protective cover, and the first body 10 is in a separated state.

[0055] Among them, the micro switch is a contact mechanism with a small gap, which performs a switching action by a specified shape and a specified force.

[0056] In an optional embodiment, take the triggering of the micro switch by the plug connector 20 as an example: in the initial position, the charging interface 102 and the charging connector 204 are plugged into each other, and there is a gap between the plug connector 20 and the micro switch. Then, the plug connector 20 is plugged in with the charging connector 204 until it contacts the micro switch. At the beginning, the plug connector 20 will not trigger the micro switch until the charging connector 204 is in place and the charging current can pass through. The plug connector will trigger the micro switch to turn on both ends of the switch. The controller 108 is electrically connected to both ends of the micro switch. When the micro switch is not triggered by the plug connector 20, it is determined that the charging device is not plugged in. At this time, the mobile power device is in an uncharged state and can be moved; when the micro switch is triggered by the plug connector 20, the micro switch is closed and turned on, and it is determined that the charging device is plugged in, limiting the operation of the mobile power device or limiting the range of movement of the mobile power device.

[0057] In another optional embodiment, take the protective cover triggering the micro switch as an example: the corresponding protective cover is provided with two states: in place state and out of place state; wherein, the protective cover in place state is the protective cover opened, and the protective cover out of place state is the protective cover closed. In the initial position, the protective cover is covered on the micro switch, the micro switch is closed and turned on, and the protective cover is not in place. At this time, the mobile power device is in an uncharged state and can be moved; when charging is required, the operator separates the protective cover from the micro switch, and the micro switch will not be triggered. At this time, the protective cover is in place, and it is determined that the mobile power device will need to be charged. At this time, the operation of the mobile power device will be restricted or the range of movement of the mobile power device will be restricted.

[0058] In other optional embodiments, the protective cover triggering the micro switch can also be implemented in other forms, for example: the protective cover is rotatably mounted on the robot, the protective cover has a first position covering the charging socket and a second position snapped at the location of the micro switch, and the corresponding protective cover is provided with two states: in place state and out of place state; wherein, the protective cover in place state is the protective cover in the second position, and the protective cover out of place state is the first position. Specifically, when the robot or robot dog or other electrical device is in use, the protective cover is snapped in the first position, at which time the micro switch will not be triggered, and the mobile electrical device is in an uncharged state and can be moved; when the robot or robot dog or other electrical device needs to be charged, the protective cover will be snapped in the second position by the user, at which time the micro switch is triggered, and it is determined that the mobile electrical device will need to be charged, and at this time the operation of the mobile electrical device will be restricted or the range of movement of the mobile electrical device will be restricted.

[0059] In other optional implementations, the sensing element may also be a pin or a Hall element, and the specific implementation will be described later. Of course, the implementation of the sensing element and the plug connector / protective cover that are not mentioned in the text is also within the protection scope of this application, as long as the detection component can detect the way it is triggered by the plug connector or the protective cover.

[0060] In this embodiment, the sensing element is triggered by the plug connector or the protective cover, and the controller determines the state of the charging socket according to the state of the sensing element, thereby ensuring the accuracy of the judgment on the charging connector in place state; the charging socket is detected by triggering the detection component instead of the charging current, thereby avoiding misjudging that the charging connector and the charging interface 102 are not plugged in when the charging connector is in place but the charging current is 0, thereby causing the plug to be damaged by dragging the wire.

[0061] See also Figure 4 , Figure 4 A circuit diagram of a detection component in an embodiment of the utility model is shown. In some embodiments, when the plug connector or the protective cover is not in place, the port of the detection component is at a high level; when the plug connector or the protective cover is in place, the port of the detection component is at a low level.

[0062] Specifically, the detection component includes a first resistor and a second resistor. The first end of the controller 108 is electrically connected to the power supply end, and the second end of the controller 108 is electrically connected to the first end of the micro switch; the first end of the first resistor is electrically connected to the first end of the controller 108, and the second end of the first resistor is electrically connected to the second end of the controller 108; the first end of the second resistor is electrically connected to the second end of the micro switch, and the second end of the second resistor is grounded.

[0063] Optionally, the controller is an MCU (Microcontroller Unit) or an MPU (Microprocessor Unit).

[0064] Specifically, the second end of the micro switch is pulled down by a resistor, and the first end of the micro switch is pulled up and connected to the second end of the controller. When the micro switch is not triggered, the second end of the controller is at a high level; when the micro switch is closed, the second end of the controller is pulled down and divided into a low level, and the corresponding state is that the charger is plugged in. Among them, the second end of the controller is an IO port (Inpot Outpot, computer input and output interface).

[0065] Taking the plug connector triggering the micro switch as an example, when the charging interface 102 is plugged into the charging connector 204, the plug connector triggers the micro switch in the charging socket. After the micro switch is closed, the first end of the micro switch and the second end of the micro switch are connected, the second end of the controller is connected to the second resistor, and the second circuit pulls down the second end of the controller to generate an interrupt. The controller determines that the charging connector 204 and the charging interface 102 are plugged in place and are in a charging state, and limits the movement of the electrical device or the movement range of the limiter; when the charging connector 204 is unplugged from the charging socket, the micro switch rebounds, the first end of the micro switch and the second end of the micro switch are disconnected, the second end of the controller is disconnected from the second resistor, and the second end of the micro switch returns to a high level. The controller determines that the charging connector 204 is not plugged in and is not in a charging state, and the movement of the electrical device is not restricted.

[0066] In other optional solutions, the solution of triggering the micro switch with the plug connector can be adapted to obtain a solution of triggering the micro switch with the protective cover.

[0067] In this embodiment, the controller pulls up the voltage through the first resistor and pulls down the voltage through the second resistor, and quickly and conveniently senses the open and closed state of the micro switch according to the high and low levels, thereby reducing the judgment process and judgment parameters; the judgment process is not affected by the charging current, and the application range of the detection component is improved.

[0068] See also Figure 1 The utility model provides a robot. In some embodiments, the robot includes a charging socket and a protective cover of any one of the other embodiments. The protective cover can be snap-fittedly installed on the charging socket, and the in-place status of the protective cover is detected by a detection component; the first end of the protective cover is rotatably connected to the charging socket, and the second end of the protective cover is arranged on the charging socket by snapping or magnetic attraction.

[0069] Specifically, the charging socket is provided on the robot, and the protective cover is buckled on the charging socket. Before charging the robot, the protective cover is opened to expose the charging interface 102 on the robot. At this time, the protective cover triggers the sensing element 106, and the detection component determines that the protective cover is in place, and the detection component limits the movement of the electrical device. When the protective cover is buckled on the charging socket, when the protective cover is not in place, the detection component keeps monitoring the state of the charging socket. When the protective cover is in place, the movement of the robot is limited or the range of movement of the robot is limited.

[0070] In this embodiment, a protective cover is provided on the charging socket of the robot. The protective cover is opened before charging, and a detection component is triggered to detect the status of the protective cover. The controller judges the status of the charging socket according to the status of the sensing element, thereby ensuring the accuracy of the judgment of the status of the charging connector. The charging socket is detected by triggering the detection component to prevent the robot from moving during charging, which may cause damage to the plug due to dragging the charging cable, and also avoid damage to the charging components of the robot. On the other hand, the detection component is triggered by the protective cover to limit the movement of the robot before the charging connector is connected, thereby reducing the probability of misoperation during the connection between the charging plug and the charging socket, making the operation process smoother.

[0071] See also Figure 5 , Figure 5 The figure is a schematic diagram of the corresponding relationship between the charging socket and the charging plug in an embodiment of the utility model. The utility model provides a plug connector. In some embodiments, the plug connector 20 is used in conjunction with the charging socket. The plug connector 20 includes a charging connector 204 and a plug connector trigger. The charging connector 204 is arranged corresponding to the charging interface 102; the plug trigger 202 corresponds to the induction element 106 and is arranged at a distance from the charging connector 204, and is used to trigger the detection component.

[0072] Exemplarily, the plug trigger 202 is an abutment surface, which is spaced apart from the charging connector 204. The first bayonet 110 is provided on the charging socket corresponding to the abutment surface. When the charging connector 204 is plugged into the charging socket, the abutment surface is plugged into the first bayonet 110. The abutment surface is cylindrical, fixed to the surface of the charging connector 204 through the rubber package of the charging connector 204, and is provided adjacent to the charging connector 204; the charging connector is symmetrical about the central axis, and the central axis of the circular bottom surface of the abutment surface coincides with the central axis of the charging connector. The first bayonet 110 is provided on the charging socket corresponding to the abutment surface, the central axis of the first bayonet 110 coincides with the central axis of the charging socket, and the first bayonet 110 is provided adjacent to the second bayonet. The second bayonet is used to pass through the charging interface 102. When the charging connector is plugged into the charging socket, the charging connector is plugged into the second bayonet, and the abutment surface is correspondingly plugged into the first bayonet 110. When the charging connector is plugged into place, the abutment surface triggers the detection component in the charging socket to detect the in-place status of the charging device.

[0073] Optionally, the plug trigger 202 is a needle, and the needle includes two connected pins. When the charging plug and the charging socket are plugged in place, the needle is connected to the detection component. Specifically, the plug trigger 202 is a needle, and the needle includes two connected pins. The connected ends of the pins are set in the rubber package of the charging connector. When the plug connector 20 is plugged into the charging socket, the two needles are respectively plugged into the pins at the second end of the controller and the pins at the first end of the second resistor, so that the second end of the controller is connected to the first end of the second resistor, and the second port of the controller is pulled down and divided into a low level. At this time, the corresponding charging plug is inserted, which limits the movement of the movable electrical device. Further, the plug trigger 202 is a pin, and the two ends of the controller are needles, and the needle includes two connected pins.

[0074] In some optional embodiments, the plug trigger 202 is a needle, which is a conductor, and the two ends of the conductor can be plugged into the pins of the second end of the controller and the pins of the first end of the second resistor, so that the second end of the controller and the first end of the second resistor are connected. Of course, as long as the needle can be matched with the pin, the specific implementation scheme is not limited to the content listed in the embodiment, and multiple pins and needle matching triggering schemes can be used.

[0075] Optionally, the plug trigger 202 is a Hall element. When the plug trigger is a Hall element, it can be interchangeable with the sensor (Hall element) on the detection component.

[0076] In this embodiment, the plug trigger is set on the charging connector to realize the function of the plug trigger to trigger the detection component when the plug connector 20 is plugged in, so that the detection component can detect the plugging state of the charging connector and the charging interface; the plug trigger and the detection component are set independently, and the plugging state of the charging connector and the charging socket can be accurately judged according to the plugging state, avoiding the detection being affected by the charging current, thereby improving the accuracy of the detection. Setting the plug trigger as a pin can reduce the number of components such as the plug micro switch required for the charging device and increase the service life of the charging connector; setting the two needle ends in the rubber package of the charging connector can avoid abnormal detection caused by accidental touch, thereby improving the accuracy of the detection of the detection component.

[0077] Combination Figure 1 and Figure 4 , Figure 4The connection diagram of the charging socket and the plug connector 20 in one embodiment of the utility model is shown. In one embodiment, the charging socket includes a second bayonet, which is opened corresponding to the charging connector; the charging interface 102 is used to plug with the charging connector, one end of the charging interface 102 is fixed to the controller, and is arranged adjacent to the induction member 106, and the other end of the charging switch is connected to the second bayonet on the charging socket. Optionally, the controller is fixedly connected to the charging socket through the second bayonet, or the fixing plate is clamped in the second socket, and the charging interface 102 is aligned with the second bayonet, and the micro switch is aligned with the first bayonet 110.

[0078] Exemplarily, the charging socket is set on the robot dog, the charging interface 102 and the micro switch on the controller are set corresponding to the second bayonet and the first bayonet 110, the controller is snapped into the charging socket, and the charging interface 102 is aligned with the second bayonet, and the micro switch is aligned with the first bayonet 110. When the robot dog needs to be charged, the charging connector is plugged into the charging interface 102, and the plug trigger 202 is synchronously plugged into the first bayonet 110; at this time, the charging connector, the second bayonet and the charging interface 102 are aligned, and the plug trigger 202, the second bayonet and the micro switch are aligned. When the charging connector is plugged into place, the plug trigger 202 abuts the micro switch, so that the two ends of the micro switch are turned on, and the second end of the controller is pulled down to a low level. The controller determines that the charging device is in place and informs the robot dog application software to limit the movement of the robot dog.

[0079] In this embodiment, the charging connector, the second bayonet and the charging interface are aligned, and the plug trigger, the second bayonet and the micro switch are aligned to ensure that when the first body is plugged into place during the plugging process, the plug trigger can accurately trigger the sensing element to detect the plug connector in place, thereby ensuring the detection accuracy of the detection component and avoiding the influence of other factors such as the charging current.

[0080] Please continue reading Figure 5 In some embodiments, the abutment surface is disposed adjacent to the charging connector, and a raised height of the abutment surface is lower than a raised height of the charging connector. When plugging in, the charging connector is first plugged into the charging interface 102. Since the raised height of the abutment surface is lower than the raised height of the charging connector, after the charging connector is inserted for a certain stroke, the abutment surface is inserted into the first bayonet 110. As the charging connector is inserted into place, the abutment surface abuts against the micro switch and triggers the detection component.

[0081] Optionally, the height of the protrusion of the abutment surface can be set according to the height relationship between the charging connector and the micro switch. Since the charging connector often has problems such as improper insertion, virtual connection, and disconnection when plugging, the height of the abutment surface can help detect connection problems.

[0082] For example, the charging connector is loosely connected to the charging interface, and the charging current flows intermittently. However, since the charging connector is not plugged in properly, the contact with the table surface does not trigger the detection component. The application software can determine that the charging device is loosely connected at this time.

[0083] Exemplarily, the central axis of the abutment surface coincides with the central axis of the charging connector, and the abutment surface includes a first column and a second column, the first column is connected to the charging connector, and the second column is connected to the first column; the diameter of the first column is larger than the diameter of the second column, and the diameter of the second column is the same as the diameter of the first bayonet. When plugging, the second column is inserted with the charging connector and has a guiding function. The second column is engaged with the first bayonet to prevent the charging connector from falling off.

[0084] In this embodiment, by limiting the position and size of the abutment surface, the abutment surface can simultaneously detect various connection problems such as virtual connection and disconnection when the detection component is triggered, thereby improving the safety performance of the charging connector and avoiding the occurrence of safety accidents; on the other hand, the abutment surface is arranged adjacent to the charging connector, which can quickly determine the plugging direction of the plug, making it easier and more convenient to use.

[0085] In some embodiments, the present invention provides a charging cable, including a plug connector as in other embodiments.
