[0025] The embodiments of the present invention solve the technical problem of low charging safety during vehicle charging in the prior art by providing a vehicle charging socket assembly and a rechargeable vehicle.

[0026] The technical solution provided by the embodiment of the present invention is to solve the above technical problems, and the overall idea is as follows:

[0027] The charging controller monitors whether the power transmission device is in the preset position of the locking mechanism. When it is detected that the power transmission device is in the preset position of the locking mechanism, the locking mechanism is controlled to lock the power transmission device. When the locking is completed, the driving device is controlled to drive the input end of the power receiving device to establish an electrical connection with the power transmission device to charge the vehicle's battery.

[0028] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0030] In a first aspect, an embodiment of the present invention provides a vehicle charging socket assembly that can be applied to vehicles equipped with batteries, such as pure electric vehicles, plug-in hybrid vehicles, and emergency power supply vehicles.

[0031] See also Figure 1 As shown, the vehicle charging socket assembly includes: a charging controller 100, a driving device 200, a locking mechanism 300 and a power receiving device 400. The driving device 200, the locking mechanism 300 and the power receiving device 400 are all electrically connected to the charging controller 100, the locking mechanism 300 is fixed on the body of the vehicle, the driving device 200 is driven to connect with the power receiving device 400, and the output end of the power receiving device 400 is connected to the battery of the vehicle.

[0032] Specifically, the charging controller 100 is used to control the locking mechanism 300 to lock the power transmitting device when it detects that the power transmitting device is in the preset position of the locking mechanism 300; and when the locking is completed, control the driving device 200 to drive the input end of the power receiving device 400 to establish an electrical connection with the power transmitting device to charge the battery of the vehicle.

[0033] During the specific implementation process, a receiving NFC (NearField Communication) coil can be pre-set at a preset position of the locking mechanism 300, and the receiving NFC coil can be connected to the charging controller 100. Correspondingly, a transmitting NFC coil paired with the above-mentioned receiving NFC coil is also set on the power transmitting device. In this way, the charging controller 100 can determine whether the power transmitting device is at the preset position of the locking mechanism 300 by determining whether the receiving NFC coil and the transmitting NFC coil have established a communication connection.

[0034] Of course, in addition to setting a receiving NFC coil on the locking mechanism 300, a Hall sensor can also be set on the locking mechanism 300 and connected to the charging controller 100, and a magnetic object can be set on the power transmitting device. In this way, the charging controller 100 can detect the distance between the power transmitting device and the locking mechanism 300 through the Hall sensor, and then determine whether the power transmitting device is in the preset position of the locking mechanism 300.

[0035] In a specific implementation process, the user may place the power transmission device at a preset position of the locking mechanism 300 . Specifically, the preset position is a position where the locking mechanism 300 can lock the power transmission device under the control of the charging controller 100 .

[0036] Different from the above-mentioned embodiment, a pressure sensor can also be set at the preset position of the locking mechanism 300. The charging controller 100 can obtain the actual pressure signal at the preset position through the pressure sensor. When the power transmission device is in the preset position, the actual pressure signal will change. Therefore, the charging controller 100 can judge whether the power transmission device is in the preset position of the locking mechanism 300 by comparing the actual pressure signal with the preset signal threshold.

[0037] In a specific implementation, the locking mechanism 300 may include an electromagnet, and correspondingly, a circle of magnetizable metal, such as iron, cobalt, nickel, and alloys thereof, may be provided on the power transmission device. Thus, when the power transmission device is in a preset position of the locking mechanism 300, the charging controller 100 can lock the power transmission device by controlling the electromagnet to generate a magnetic field.

[0038] In a specific implementation, the driving device 200 may be a pair of electromagnets, specifically, one of the electromagnets may be disposed on the power receiving device 400, and the other electromagnet may be disposed on the locking mechanism 300 or on other fixed parts of the vehicle, such as a vehicle frame. In this way, the electrical connection between the input end of the power receiving device 400 and the power transmitting device may be established by controlling the pair of electromagnets to attract or repel each other.

[0039] For example, if one of the electromagnets is disposed on the locking mechanism 300 and the other electromagnet is disposed on the power receiving device 400, the pair of electromagnets can be controlled to attract each other. Thus, the power receiving device 400 can approach the locking mechanism 300 under the action of the magnetic attraction force, thereby establishing an electrical connection between the power receiving device 400 and the power transmitting device.

[0040] In a specific implementation process, the power receiving device 400 may be a charging socket paired with the power transmitting device.

[0041] Regarding the locking mechanism 300, in a specific implementation process, the locking mechanism 300 may include: a locking actuator (not shown) and a locking controller (not shown) connected to the locking actuator. When the charging controller 100 detects that the power transmission device is in the preset position of the locking mechanism 300, it sends a locking instruction to the locking controller; the locking controller responds to the locking instruction and controls the locking actuator to lock the power transmission device.

[0042] In some embodiments, the locking actuator may be a motor with a locking protrusion on the rotating shaft, and the locking controller may be a motor controller. Correspondingly, the power transmission device is provided with a locking groove that matches the locking protrusion. In this way, when the motor controller receives a locking instruction, it can control the motor to rotate a certain angle so that the locking protrusion matches the locking groove, thereby completing the locking of the power transmission device.

[0043] Different from the above embodiment, the locking actuator can also be an electromagnet, the locking controller can also be an electromagnetic relay, and correspondingly, a permanent magnet is provided on the power transmission device. In this way, when the electromagnetic relay receives the locking instruction, the current loop of the electromagnet is connected to make the electromagnet generate a magnetic field, and then the electromagnet and the permanent magnet are magnetically attracted to each other to complete the locking of the power transmission device.

[0044] With respect to the driving device 200, in a specific implementation process, the driving device 200 may include: a driving controller (not shown) and a driving actuator (not shown) connected to the driving controller, wherein the driving actuator is driven to connect with the power receiving device 400. When the charging controller 100 detects that the locking mechanism 300 has completed locking the power transmitting device, it sends a connection driving instruction to the driving controller; the driving controller responds to the connection driving instruction and controls the driving actuator to operate so that the input end of the power receiving device 400 is electrically connected to the power transmitting device.

[0045] In some embodiments, the driving actuator may be a hydraulic rod, one end of which is connected to the power receiving device 400, and the other end of which may be connected to the locking mechanism 300, or may be connected to other fixed parts of the vehicle, such as a frame or a body. Correspondingly, the driving controller may be an electronically controlled hydraulic pump. When the electronically controlled hydraulic pump receives a connection drive instruction, it operates and can establish an electrical connection between the power receiving device 400 and the power transmitting device by controlling the extension or contraction of the hydraulic rod.

[0046] Different from the above-mentioned embodiment, the driving actuator can also be composed of a reduction gear set and a driving motor, and a rack corresponding to the reduction gear set is provided on the power receiving device 400, and the driving controller can be a driving motor controller. In this way, when the driving motor controller receives the connection drive instruction, it controls the driving motor to drive the reduction gear set to rotate, so that the power receiving device 400 moves relative to the reduction gear, so that the input end of the power receiving device 400 is electrically connected to the power transmitting device.

[0047] With respect to the power receiving device 400, in a specific implementation process, the power receiving device 400 may include: a power receiving cable (not shown) and a power receiving switch (not shown) connected to the power receiving cable, the input end of the power receiving cable is connected to the power transmitting device, and the output end of the power receiving cable is connected to the battery. When the charging controller 100 detects that the power receiving device 400 is electrically connected to the power transmitting device, it sends a charging instruction to the power receiving switch; the power receiving switch responds to the charging instruction and closes the power receiving cable to charge the battery.

[0048] In the specific implementation process, in order to prevent the power receiving device 400 from being misaligned during the movement process, which results in the inability to establish an electrical connection with the power transmitting device, see Figures 2 to 4 As shown, the locking mechanism 300 may further include: a charging guide mechanism 301. Specifically, the power receiving device 400 is slidably assembled on the charging guide mechanism 301, and the charging guide mechanism 301 is used to guide the power receiving device 400 during the process of the driving device 200 driving the power receiving device 400, so that the input end of the power receiving device 400 is electrically connected to the power transmitting device, which effectively improves the reliability of the process of establishing the electrical connection.

[0049] It should be noted that, in the process of establishing an electrical connection between the input end of the power receiving device 400 and the power transmitting device, the power receiving device 400 slides on the charging guide mechanism 301 in a direction close to the locking mechanism 300 under the drive of the driving device 200; in the process of disconnecting the electrical connection between the input end of the power receiving device 400 and the power transmitting device, the power receiving device 400 slides on the charging guide mechanism 301 in a direction away from the locking mechanism 300 under the drive of the driving device 200. The above-mentioned battery is used to provide the driving device 200 with the electrical energy required for operation, and the battery can be a lead-acid battery or a lithium battery.

[0050] In some embodiments, see Figures 5-6 As shown, a spring 500 may be mounted on the charging guide mechanism 301 to reset the power receiving device 400 when there is no driving device 200. Figure 5 As shown, when the charging controller 100 detects that the locking mechanism 300 is not connected to the power transmitting device, the charging controller 100 controls the driving device 200 to operate, so that the power receiving device 400 slides on the charging guide mechanism 301 in a direction away from the locking mechanism 300. At this time, the spring 500 is in a compressed state; see Figure 6 As shown, when the charging controller 100 detects that the locking mechanism 300 is docked with the power transmitting device, the charging controller 100 controls the driving device 200 to operate, so that the power receiving device 400 slides on the charging guide mechanism 301 in a direction close to the locking mechanism 300, and the spring 500 is in a stretched state.

[0051] In some embodiments, the charging controller 100 is also used to control the operation of the driving device 200 when receiving a charging disconnection signal sent by the vehicle controller, so as to drive the input end of the power receiving device 400 to disconnect electrically from the power transmitting device, thereby ending the charging of the battery; and after disconnecting the electrical connection, control the locking mechanism 300 to unlock the power transmitting device.

[0052] In the specific implementation process, the charging controller 100 is also used to send a power-off instruction to the power receiving controller when receiving a charging disconnection signal; the power receiving controller disconnects in response to the power-off instruction, so that the power receiving cable is in a disconnected state to end charging of the battery.

[0053] In the specific implementation process, the charging controller 100 is also used to send a disconnect drive instruction to the drive controller when it is detected that the power receiving switch is disconnected; the drive controller responds to the disconnect drive instruction and controls the drive actuator to operate so that the input end of the power receiving device 400 is electrically disconnected from the power transmitting device.

[0054] In the specific implementation process, the charging controller 100 is also used to send an unlocking command to the locking controller when it detects that the input end of the power receiving device 400 is electrically disconnected from the power transmitting device; the locking controller responds to the unlocking command and controls the locking actuator to unlock the power transmitting device.

[0055] It should be noted that the charging controller 100 may be a PLC (Programmable Logic Controller) or a microcomputer; the power transmission device may be a charging gun connected to a charging pile or a vehicle charging plug.

[0056] In a second aspect, an embodiment of the present invention provides a rechargeable vehicle, see Figure 7 As shown, the vehicle includes a vehicle body 701, a power battery 702, a power motor 703, and any vehicle charging socket assembly 704 in the first aspect. The vehicle charging socket assembly 704 is electrically connected to the power battery 702, the power battery 702 is electrically connected to the power motor 703, and the power battery 702, the power motor 703, and the vehicle charging socket assembly 704 are all arranged on the vehicle body 701.

After locking, the input end of the power receiving device 400 is electrically connected to the power transmission device by controlling the driving device 200, thereby charging the battery. Therefore, the user does not need to manually connect the power transmission device to the input end of the power receiving device 400, thereby preventing the user from touching the power transmission device during the process of establishing the charging connection, thereby improving the safety and convenience of the charging process.

[0059] 2. Since the locking mechanism 300 also includes a charging guide mechanism 301, and the power receiving device 400 is slidably assembled on the charging guide mechanism 301, the charging guide mechanism 301 can guide the power receiving device 400 during the process of the driving device 200 driving the power receiving device 400, so that the input end of the power receiving device 400 establishes an electrical connection with the power transmitting device, thereby improving the reliability of the process of establishing an electrical connection between the power receiving device 400 and the power transmitting device.
