[0025] The following further describes the specific embodiments of this application with reference to the drawings.

[0026] It is easy to understand that, according to the technical solution of the present application, under the condition of not changing the essential spirit of the present application, there are various structural ways and implementation ways that can be mutually replaced by those of ordinary skill in the art. Therefore, the following specific embodiments and drawings are only illustrative descriptions of the technical solution of the present application, and should not be regarded as all of the present application or as a limitation or restriction on the technical solution of the application.

[0027] This embodiment provides a charging door integrated with an indicating component, as Figure 1 shown, which includes a first housing 1 and a second housing 3. The first housing 1 is used to be installed on the charging door base 2 of the vehicle body (the first housing 1 and the charging door base 2 can be substantially flush or protrude in a specific shape), and a first opening and closing member 11 is provided on its inner wall; the second housing 3 is pivotally connected to the first housing 1, and a second opening and closing member 31 and a non-contact sensor 4 are provided on its inner wall; the second opening and closing member 31 cooperates with the first opening and closing member 11 to realize the opening or closing of the second housing 3 and the first housing 1. As shown in the figure, the pivotal connection can be realized through a pivot shaft 6. As Figure 2 shown is a control module main board 5, and the control module main board 5 is arranged inside the first housing 1. Combining Figure 2 and Figure 3 shown, a position response module, an indicator light module and a signal transmission interface are integrated on the control module main board 5. The signal transmission interface includes a first interface 71, a second interface 72, a third interface 73 and a fourth interface 74; the position response module cooperates with the non-contact sensor 4 to detect the moving direction of the second housing 3 and its relative position with respect to the first housing 1, and the position response module transmits the detection result to the vehicle controller through the signal transmission interface. For example, when the second housing 3 approaches the first housing 1, a signal indicating the approach between the second housing 3 and the first housing 1 is sent to the vehicle controller, that is, the charging door is in the closing process state. When the second housing 3 is locked with the first housing 1, a signal indicating the locking between the second housing 3 and the first housing 1 is sent to the vehicle controller, that is, the charging door is closed. When the second housing 3 moves away from the first housing 1, a signal indicating the separation between the second housing 3 and the first housing 1 is sent to the vehicle controller, that is, the charging door is in the opening process state. When the second housing 3 is completely opened from the first housing 1, a signal indicating the opening of the charging door is sent to the vehicle controller. The indicator light module receives the vehicle signal sent by the vehicle controller through the signal transmission interface and controls the indicator light to work in a lighting state corresponding to the charging state in the vehicle signal. The vehicle signal sent by the vehicle controller includes a charging state, and the charging state includes standby, charging gun inserted, charging in progress, charging power, etc. The indicator light indicates different charging states through different lighting states.

[0028] In the above solution, the charging door includes a first housing 1 and a second housing 3, and the first housing 1 and the second housing 3 are pivotally connected. The first housing 1 is installed on the charging door base 2, and the second housing 3 approaches or moves away from the first housing 1 to close or open the charging door. The first opening and closing member 11 and the second opening and closing member 31 cooperate to close and open, so as to lock or unlock the second housing 3 and the first housing 1. A non-contact sensor 4 is provided on the inner wall of the second housing 3, and a control module main board 5 is arranged inside the first housing. A position response module, an indicator light module and a signal transmission interface are integrated on the control module main board 5. The position response module cooperates with the non-contact sensor 4 to detect the moving direction of the second housing 3 and its relative position with the first housing 1, and transmits the detection result to the vehicle controller through the signal transmission interface. The indicator light module receives the vehicle signal sent by the vehicle controller through the signal transmission interface and controls the indicator light to work in a light-emitting state corresponding to the charging state signal. In the above solution, the non-contact sensor and the position response module are used in cooperation to detect the position state of the charging door. The non-contact sensor is directly arranged inside the second housing, and the position response module is integrated on the control module main board, without occupying any additional space position at all. In addition, the charging state can be indicated by the indicator light, and the indicator light module is also integrated on the control module main board, without occupying additional space. The charging door of the present application integrates position detection and status indication in the charging door. The use of the non-contact sensor can reduce the occupied space, improve the compatibility and adaptability with other components. The position response module and the indicator light module are both arranged on the control module main board. The whole charging door has the advantages of high integration, low energy consumption and strong coordination.

[0029] In the above solution, the non-contact sensor 4 may include a laser sensor, an ultrasonic sensor, a Hall sensor, a radio frequency identification (RFID) sensor, etc. The laser sensor uses a laser beam to detect the position and distance of the second housing. It can measure the time for the laser to travel back and forth by emitting and receiving laser pulses, and calculate the distance from the first housing 1 and the second housing 3. The ultrasonic sensor utilizes the propagation characteristics of ultrasonic waves in the air to detect information such as the distance and position between the two housings by emitting and receiving ultrasonic signals. The principle of the Hall sensor is that when a magnetic field acts on the Hall element, a Hall voltage is generated. By detecting this voltage, the change in the magnetic field can be sensed, and then the position parameters of the object can be measured. Therefore, by setting a magnetic field element on the first housing 1, a Hall element and a sensing element for voltage detection of the Hall element in the position response module, when the distance between the second housing 3 and the first housing 1 changes, the distance between the magnetic field element and the Hall element changes, and the voltage generated by the Hall element changes. By presetting the mapping relationship between the Hall element voltage and the distance, the corresponding distance data can be found after detecting the Hall element voltage. The radio frequency identification (RFID) sensor consists of a reader and an electronic tag. The reader communicates with the electronic tag through radio frequency signals to realize the identification and information reading of the object attached to the tag. Therefore, the reader and the electronic tag can be respectively arranged in the first housing 1 and the second housing 3 to achieve distance measurement. The above description of the non-contact sensor 4 is only an example. In actual application, measurement elements with pairing functions can be selected and arranged in the first housing 1 and the second housing 3 respectively for distance measurement.

[0030] In the above solution of the present application, during the process of the second housing 3 approaching the first housing 1, if the position response module detects that the position of the non-contact sensor 4 reaches the set position, it is determined that the first housing 1 and the second housing 3 are in the closed state. This set position can be selected according to an empirical value, that is, after reaching this position, the first opening and closing member 11 and the second opening and closing member 31 are basically in contact, and as long as they are further approached, the first opening and closing member 11 and the second opening and closing member 31 can be locked. Correspondingly, during the process of the second housing 3 moving away from the first housing 1, if the position response module detects that the position of the non-contact sensor 4 reaches the set position, it is determined that the first housing 1 and the second housing 3 are in the open state. As mentioned above, the set position can be selected according to an empirical value, that is, after reaching this position, the first opening and closing member 11 and the second opening and closing member 31 are only in contact and not yet locked, and as long as they are further moved away, the first opening and closing member 11 and the second opening and closing member 31 can be fully unlocked to open the charging door.

[0031] Preferably, the position response module detects and records the distance between the non-contact sensor and the position response module at a set period; if the distance shows a decreasing trend, it is determined that the second housing 3 approaches the first housing 1, and if the distance shows an increasing trend, it is determined that the second housing 3 moves away from the first housing 1. The distance collected each time can be marked in a coordinate system, and as time changes, the distances collected continuously multiple times can be recorded in the coordinate system, and whether the distance trend is increasing or decreasing can be visually displayed, so that the position change of the second housing 3 can be obtained simply and accurately.

[0032] In some preferred solutions, in the indicator light module, when the indicator light is a single-color LED, the indicator light module adjusts the signal frequency and duty cycle according to the charging status adjustment signal in the vehicle signal sent by the vehicle controller to control the single-color LED to be in a constant-on, breathing or flashing light-emitting state. As shown in Figure 4 It can be seen that the operations of adjusting the signal frequency and duty cycle can be realized through an LED driving chip. By controlling the single-color LED to be in a constant-on, breathing or flashing light-emitting state, it can be used to indicate the charging status, and the charging status can include handshake with the charging pile, charging in progress, charging completed, reserved charging and charging failure, etc. Further, when the single-color LED is in a breathing or flashing light-emitting state, its breathing or flashing rate is controlled. In this solution, different light languages of the single-color LED can represent various states, but the volume of the charging door does not need to be increased, still meeting the requirements of miniaturization and integration of vehicle design. As another implementation method, in the indicator light module, when the indicator light is a multi-color LED, the indicator light module adjusts the signal frequency, duty cycle and light-emitting color according to the charging status adjustment signal in the vehicle signal sent by the vehicle controller to control the multi-color LED to be in a constant-on, breathing or flashing light-emitting state with a specific color light. That is, the multi-color LED can represent more states than the single-color LED. In specific implementation, the control circuit framework shown in Figure 4 can be adopted, and the resistors, triodes / MOS transistors therein can be realized by using existing electronic components. In the figure, V BAT represents the power supply of the vehicle, VICM represents the vehicle interface control module, and BCM represents the body control module, that is, VICM and BCM represent the vehicle controller. As shown in Figures 2 to 4As shown, it can be communicatively connected to the vehicle controller through the signal transmission interface. The main board of the control module receives the vehicle signals sent by the vehicle controller. The vehicle signals include the charging status signal. The lighting state of the indicator light is controlled through the indicator light module to prompt the charging status of the vehicle. Therefore, in the solution of this embodiment, the signal transmission interface sends the opening and closing states of the first housing 1 and the second housing 1 to the vehicle controller. The vehicle controller can send the charging status to the main board of the control module, and thus different charging statuses, vehicle statuses, etc. are represented by different states of the LED.

[0033] Further preferably, as Figure 5 shown, the position response module is also used to connect to the indicator light module. The position response module sends the detection result to the indicator light module, and the indicator light module controls the indicator light to work in a lighting state corresponding to the detection result. When the second housing 3 is opened, the indicator light can prompt that the second housing 3 is in the open state, and this state can prompt the operator to insert the charging gun to perform charging.

[0034] During specific connection, the first interface 71 can be connected to the power supply (i.e., the entire main board of the control module is powered through the first interface 71), the second interface 72 is connected to the signal line (such as the position response module feeds back the opening and closing states of the vehicle charging door through the second interface 72), the third interface 73 is connected to the ground, and the fourth interface 74 is connected to the vehicle LIN line (i.e., the vehicle signals sent by the vehicle controller can be received through the fourth interface 74). In specific implementation, the first opening and closing member 11, the second opening and closing member 31, the non-contact sensor 4, and the main board of the control module are all located at positions opposite to the pivot position, that is, at the distal end of the pivot axis. Such a setting can avoid the influence of the opening and closing process of the charging door on the detection of the position response.

[0035] The embodiment of the present application also provides a vehicle, and the vehicle includes the charging door integrating the indicating component described in the foregoing embodiment.

[0036] According to needs, the above technical solutions can be combined to achieve the best technical effect.

[0037] The above are only the principles and preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, based on the principles of the present application, several other modifications can also be made, which should also be regarded as the protection scope of the present application.
